Abstract

A workbench for mounting an electrical function test unit includes: a mounting surface for mounting the electrical function test unit, wherein the mounting surface is provided with a connecting area, and a number of mounting through holes are arranged in the connecting area; and connectors detachably connected with the mounting through holes and configured to match with mounting screws of the electrical function test unit when the electrical function test unit is mounted on the workbench. The workbench has long service life, reduces the replacement difficulty of the electrical function test unit and shortens the downtime, thereby improving the detection efficiency of the display screen.

First claim

The invention claimed is:

1. A workbench for mounting an electrical function test unit, comprising:
a mounting surface for mounting the electrical function test unit, wherein the mounting surface is provided with a connecting area, and a plurality of mounting through holes are arranged in the connecting area; and
connectors detachably connected with the mounting through holes and configured to match with mounting screws of the electrical function test unit when the electrical function test unit is mounted on the workbench;
wherein each of the mounting through holes is provided with one of the connectors; and
wherein each connector is in clearance fit with each corresponding mounting through hole and an outer periphery of a radial cross section of each connector is in a regular hexagonal shape along an extending direction of the mounting surface, and a radial cross section of each corresponding mounting through hole is in a regular hexagonal shape corresponding to the shape of the outer periphery of the radial cross section of the connector.

2. The workbench according to claim 1 , wherein each connector is provided with external thread, and each connector is in threaded connection with each corresponding mounting through hole.

3. The workbench according to claim 2 , wherein each connector is provided with internal thread, the external thread and the internal thread having opposite helical directions.

4. The workbench according to claim 1 , wherein each connector is inserted into each corresponding mounting through hole.

5. The workbench according to claim 4 , wherein the outer periphery of the radial cross section of each connector forms an interference fit with each corresponding mounting through hole.

6. The workbench according to claim 4 , wherein each mounting through hole is provided with an internal thread, and when mounting, a tightening force between the internal thread of each mounting through hole and the external thread of each connector is greater than a tightening force between the internal thread of each connector and each mounting screw of the electrical function test unit.

7. The workbench according to claim 6 , wherein an end face of each connector facing the mounting surface does not extend beyond the mounting surface.

8. The workbench according to claim 7 , wherein an end face of each connector facing away from the mounting surface does not extend beyond a surface of the workbench facing away from the mounting surface.

9. The workbench according to claim 5 , wherein each connector is provided with an internal thread, and a static friction force of the interference fit between the outer periphery of the radial cross section of each connector and each mounting through hole is greater than a screwing force between each mounting screw and the internal thread of each connector.

10. An electrical function test machine comprising an electrical function test unit and a workbench for mounting the electrical function test unit, wherein the workbench comprises:
a mounting surface for mounting the electrical function test unit, wherein the mounting surface is provided with a connecting area, and a plurality of mounting through holes are arranged in the connecting area;
connectors detachably connected with the mounting through holes and configured to match with mounting screws of the electrical function test unit when the electrical function test unit is mounted on the workbench;
wherein each of the mounting through holes is provided with one of the connectors; and
wherein each connector is in clearance fit with each corresponding mounting through hole and an outer periphery of a radial cross section of each connector is in a regular hexagonal shape along an extending direction of the mounting surface, and a radial cross section of each corresponding mounting through hole is in a regular hexagonal shape corresponding to the shape of the outer periphery of the radial cross section of the connector.

11. The electrical function test machine according to claim 10 , wherein each connector is provided with an external thread, and each connector is in threaded connection with each corresponding mounting through hole.

12. The electrical function test machine according to claim 11 , wherein each connector is provided with an internal thread, and an external thread and the internal thread have opposite helical directions.

13. The electrical function test machine according to claim 10 , wherein each connector is inserted into each corresponding mounting through hole.

14. The electrical function test machine according to claim 13 , wherein each connector is in interference fit with each corresponding mounting through hole.

15. The electrical function test machine according to claim 12 , wherein each mounting through hole is provided with an internal thread, and a tightening force between the internal thread of each mounting through hole and the external thread of each connector is greater than a tightening force between the internal thread of each connector and each mounting screw of the electrical function test unit during mounting.

16. The electrical function test machine according to claim 14 , wherein each connector is provided with an internal thread, and a static friction force of the interference fit between the outer periphery of the radial cross section of each connector and each corresponding mounting through hole is greater than a screwing force between each mounting screw and the internal thread of each connector.
