Abstract

Disclosed herein is a head fixture for adhesively bonding a part of a golf club head to a body of the golf club head. The head fixture includes a bottom portion, including a body retainer, and a top portion, selectively attachable to the bottom portion and including pressure applicators spaced apart about the top portion. Each one of the pressure applicators comprises a ratcheting mechanism and a ribbed shaft engaged with the ratcheting mechanism such that, when the top portion is selectively attached to the bottom portion, the ribbed shaft is movable away from the body retainer into a position, associated with a pressure applied to the part of the golf club head by the ribbed shaft, and the ribbed shaft is non-movably fixable, relative to the body retainer, in the position.

First claim

What is claimed is:

1. A method of adhesively bonding a part of a golf club head to a body of the golf club head, the method comprising steps of:
positioning a golf club head assembly, comprising the part and the body, onto a bottom portion of a head fixture;
attaching a top portion of the head fixture to the bottom portion of the head fixture when the golf club head assembly is retained by the bottom portion of the head fixture;
when attaching the top portion of the head fixture to the bottom portion of the head fixture, biasing pressure applicators of the top portion of the head fixture into contact with the part of the golf club head, such that a pressure is applied onto the part of the golf club head;
locking the pressure applicators, such that the pressure applied onto the part of the golf club head is maintained; and
when the pressure applicators are locked, unbiasing the pressure applicators.

2. The method according to claim 1 , wherein the part comprises a strike plate.

3. The method according to claim 1 , wherein the part comprises a crown insert.

4. The method according to claim 1 , further comprising steps of:
moving the head fixture, when the pressure applicators are locked and the pressure applied onto the part is maintained, into a curing apparatus; and
curing an adhesive between the part and the body when the head fixture is in the curing apparatus.

5. The method according to claim 1 , further comprising steps of:
applying adhesive onto the body and the part of the golf club head;
attaching the part of the golf club head to the body of the golf club head to form the golf club assembly; and
electronically scanning the part and the body of the golf club head, to determine a position and orientation of the part and the body of the golf club head, after applying the adhesive onto the body and the part of the golf club head and before attaching the part of the golf club head to the body of the golf club head.

6. The method according to claim 1 , further comprising unlocking the pressure applicators when the pressure applicators are biased into contact with the part of the golf club head, wherein:
locking the pressure applicators comprises inserting a detent ball within a gap defined between adjacent ribs of a ribbed shaft and a housing surrounding the ribbed shaft, of each one of the pressure applicators, so that the ribbed shaft is not movable relative to the housing of each one of the pressure applicators; and
unlocking the pressure applicators comprises moving the detent ball out of the gap so that the ribbed shaft is movable relative to the housing of each one of the pressure applicators.

7. The method according to claim 6 1 , wherein:
locking the pressure applicators comprises moving the housings of the pressure applicators, relative to the detent ball, in a first direction; and
unlocking the pressure applicators comprises moving the housings of the pressure applicators, relative to the detent ball, in a second direction that is opposite the first direction.

8. The method according to claim 7 , wherein moving the housings of the pressure applicators in the first direction comprises translationally moving the housings towards or away from the bottom portion of the head fixture.

9. The method according to claim 7 , further comprising biasing the housings into a locked position associated with locking of the pressure applicators.

10. The method according to claim 6 , wherein the step of biasing the pressure applicators into contact with the part of the golf club head comprises biasing padded tips of the ribbed shafts of the pressure applicators into contact with the part of the golf club head.

11. The method according to claim 1 , wherein the step of locking the pressure applicators comprises locking each pressure applicator of the pressure applicators by engaging a ratcheting mechanism of the pressure application with a ribbed shaft of the pressure applicator.

12. The method according to claim 1 , wherein the steps of biasing, locking, and unbiasing the pressure applicators comprises biasing, locking, and unbiasing between, and inclusive of, three and thirteen pressure applicators.

13. The method according to claim 12 , wherein the steps of biasing, locking, and unbiasing the pressure applicators comprises biasing, locking, and unbiasing between, and inclusive of, five and eight pressure applicators.

14. The method according to claim 1 , wherein the step of biasing the pressure applicators comprises biasing the pressure applicators into contact with the part of the golf club head at corresponding locations on the golf club head, and wherein the corresponding locations form a non-symmetrical pattern.

15. The method according to claim 1 , wherein the step of biasing the pressure applicators comprises biasing at least two of the pressure applicators into contact with the part of the golf club head at corresponding locations proximate a forward portion of the golf club head, biasing at least two of the pressure applicators into contact with the part of the golf club head at corresponding locations proximate a middle portion of the golf club head, and biasing at least two of the pressure applicators into contact with the part of the golf club head at corresponding locations proximate a rearward portion of the golf club head.

16. The method according to claim 1 , wherein the step of attaching the top portion to the bottom portion comprises clamping together the top portion and the bottom portion.

17. The method according to claim 1 , wherein the step of positioning the golf club head assembly onto the bottom portion of the fixture comprises nestably receiving the body of the golf club head assembly in a recess of a body retainer of the bottom portion.

18. The method according to claim 1 , further comprising detaching the top portion of the head fixture from the bottom portion of the head fixture via a fixture-setting device before the step of positioning the golf club head assembly onto the bottom portion of the head fixture.

19. The method according to claim 18 , further comprising, before positioning the golf club head assembly onto the bottom portion of the head fixture, moving the bottom portion of the head fixture away from the fixture-setting device and onto a platform, positioning the part on the platform, and positioning just the body onto the bottom portion of the head fixture via at least one robot.

20. The method according to claim 19 , wherein the step of positioning the golf club head assembly onto the bottom portion of the head fixture comprises attaching the part to the body via the at least one robot after the body is positioned onto the bottom portion of the head fixture.

21. The method according to claim 19 , wherein the top portion of the head fixture is attached to the bottom portion of the head fixture via the fixture-setting device.

22. The method according to claim 19 , further comprising applying an adhesive onto the body and the part via the at least one robot before the part is attached to the body.

23. The method according to claim 22 , further comprising flipping over the part after the adhesive is applied onto the part and before the part is attached to the body.

24. The method according to claim 22 , wherein:
the bottom portion of the head fixture is moved away from the fixture-setting device and onto the platform, and the part is attached to the body, via a first robotic arm;
the part i
