Abstract

An attaching apparatus is provided and includes: a base and a cover pivotally connected to the base. The base includes a to-be-attached object positioning portion for positioning and fixing the to-be-attached object. The cover includes an adhesive positioning portion for positioning and fixing the adhesive. The cover is rotatable relative to the base between an opening position and a closing position where the adhesive in the adhesive positioning portion is pressed against the to-be-attached object in the to-be-attached object positioning portion.

First claim

What is claimed is:

1. An attaching apparatus for attaching adhesive to a to-be-attached object, comprising:
a base; and
a cover pivotally connected to the base;
wherein the base includes a to-be-attached object positioning portion configured to position and fix the to-be-attached object; and the cover includes an adhesive positioning portion configured to position and fix the adhesive; and
wherein the cover is rotatable relative to the base between an opening position and a closing position where the adhesive in the adhesive positioning portion is pressed on the to-be-attached object in the to-be-attached object positioning portion.

2. The attaching apparatus of claim 1 , wherein the adhesive positioning portion includes:
an adsorption plate configured to fix the adhesive by means of adsorption; and
a positioning frame around an outer periphery of the adsorption plate and configured to position the adhesive;
wherein the adsorption plate is movable back and forth relative to the positioning frame in a direction perpendicular to an adsorption surface of the adsorption plate, thereby enabling the positioning frame to protrude from the adsorption plate to position the adhesive when the cover is at the opening position, and enabling the adsorption plate to push the adhesive out of the positioning frame and to press the adhesive on the to-be-attached object when the cover is at the closing position.

3. The attaching apparatus of claim 2 , wherein the positioning frame includes at least two positioning bars that are perpendicular to each other and are configured to position one corner of the adhesive.

4. The attaching apparatus of claim 2 , wherein the cover further includes: an annular protruding prismoid at a periphery of the adsorption surface of the adsorption plate.

5. The attaching apparatus of claim 2 , wherein the cover further includes a driving mechanism; and the driving mechanism includes a driving cylinder configured to drive the adsorption plate to move, and a guiding member configured to guide a movement direction of the adsorption plate.

6. The attaching apparatus of claim 5 , wherein the guiding member includes a linear bearing on the adsorption plate and a positioning pin that engages with the linear bearing.

7. The attaching apparatus of claim 2 , wherein the base further includes an adsorption control switch that controls on or off of an adsorption function of the adsorption plate;
wherein the adsorption control switch is at such a position that the cover contacts the adsorption control switch when the cover is at the closing position, thereby enabling the cover to trigger the adsorption control switch when the cover is at the closing position and then controlling the adsorption plate to turn off the adsorption function.

8. The attaching apparatus of claim 1 , wherein the base further includes supporting poles configured to support the cover; and the supporting poles are movable up and down in a direction perpendicular to a fixing surface of the to-be-attached object positioning portion.

9. The attaching apparatus of claim 1 , wherein the cover includes a first magnetic member, and the base includes a second magnetic member; and
wherein the second magnetic member is at such a position that when the cover is at the closing position, the second magnetic member attracts and fixes the first magnetic member, thereby fixing the cover.

10. The attaching apparatus of claim 9 , wherein at least one of the first magnetic member and the second magnetic member is an electromagnet.

11. The attaching apparatus of claim 10 , further comprising a control switch that serves as both of a control switch for the electromagnet and a movement control switch for the adsorption plate.

12. The attaching apparatus of claim 1 , wherein the base further includes a position adjustment mechanism configured to adjust a position of the to-be-attached object positioning portion.

13. The attaching apparatus of claim 12 , wherein the position adjustment mechanism includes a micrometer.

14. The attaching apparatus of claim 1 , wherein the base further includes an installation plate with a supporting platform configured to support the cover when the cover is at the opening position.

15. The attaching apparatus of claim 14 , wherein the supporting platform has an inclined supporting surface, and the inclined supporting surface is inclined with respect to a top surface of the base.

16. The attaching apparatus of claim 15 , wherein an angle between the inclined supporting surface and the top surface of the base is equal to an angle between the cover at the opening position and the top surface of the base.

17. An attaching method for attaching adhesive to a to-be-attached object with the attaching apparatus of claim 1 , the method comprises:
rotating the cover to the opening position, fixing a release film of the frame sealant to the adhesive positioning portion and fixing the to-be-attached object to the to-be-attached object positioning portion; and
rotating the cover towards the base until the cover reaches the closing position where the adhesive in the adhesive positioning portion is pressed on the to-be-attached object in the to-be-attached object positioning portion.

18. The attaching method of claim 17 , wherein the adhesive positioning portion includes: an adsorption plate configured to fix the adhesive by means of adsorption and a positioning frame around an outer periphery of the adsorption plate and configured to position the adhesive;
the base further includes an adsorption control switch that controls on or off of an adsorption function of the adsorption plate;
the cover further includes a driving mechanism; and the driving mechanism includes a driving cylinder configured to drive the adsorption plate to move, and a guiding member configured to guide a movement direction of the adsorption plate;
the fixing a release film of the frame sealant to the adhesive positioning portion, includes: placing the release film of the frame sealant into the positioning frame, and fixing the release film of the frame sealant to the adhesive positioning portion by the adsorption plate by means of adsorption;
the rotating the cover towards the base until the cover reaches the closing position where the adhesive in the adhesive positioning portion is pressed on the to-be-attached object in the to-be-attached object positioning portion, includes:
pressing, by the cover when the cover is rotated to the closing position, the adsorption control switch and a movement control switch for the adsorption plate, thereby enabling the adsorption plate to turn off the adsorption function and enabling the driving cylinder to push the adsorption plate to move downward under guidance of the guiding member until a protruding prismoid on the adsorption plate presses an effective region of a sealant body of the frame sealant to the to-be-attached object in the to-be-attached object positioning portion.

19. The attaching method of claim 17 , further comprising:
releasing the movement control switch for the adsorption plate, thereby enabling the driving cylinder to drive the adsorption plate to move upwardly to return back.
