Description

Technical Field

[0001] The utility model relates to the technical field of main board test tooling equipment, and specifically relates to a test tooling for a TV main board. Background Technique

[0002] Currently, when testing and repairing the main board of a liquid crystal TV, a test or repair tooling platform converted from a whole TV set is used for testing and repairing. With the increasing popularity of liquid crystal TVs, the production volume and the number of units in use are getting larger and larger, and the models of the main boards and display screens of the TVs are also increasing. Correspondingly, the number and types of tooling platforms have also increased. In the prior art, there is no function to automatically convey the tooling after the test to the next detection point, and at the same time, it can only limit the main board of the TV in a single direction, lacking the function of fixing in multiple directions.

[0003] For example, a main board voltage stabilization plug-in test tooling disclosed in the authorized patent document with the application number CN202322821085.7 includes a base. A carrier is rotatably connected to the top of the base. Threaded holes are provided on both the front and rear sides of the top of the carrier. A U-shaped plate is fixedly provided at the bottom on the right side of the base, and a moving block is arranged inside the U-shaped plate. For this main board voltage stabilization plug-in test tooling, by starting the first driving motor to rotate the first lead screw, the moving block threadedly connected to the surface of the first lead screw is driven to move up or down, so as to adjust the height of the test assembly, so that the height of the profiling plug and the edge interface on the surface of the main board are in the same plane. Then, by starting the second driving motor to rotate the second lead screw, the mounting plate moves forward or backward on the left side of the moving block, so as to switch the profiling plug corresponding to the edge interface on the surface of the main board. The position of the profiling plug is adjustable, so as to facilitate the connection test of main board interfaces of different specifications, and thus improve the applicability of the test tooling.

[0004] The above patent does not have the function of automatically conveying the tooling after the test to the next detection point and lacks the function of fixing in multiple directions. Therefore, we need to provide a test tooling for a TV main board. Content of the Utility Model

[0032] Please refer to Figures 1 to 3 , the adjusting member 4 includes two double threaded rods 41 arranged on the front and back of the test frame 1, and fixing blocks 42 are rotatably installed at both ends of the two double threaded rods 41 to facilitate adjusting the position of the double threaded rod 41 relative to the fixing block 42. The fixing blocks 42 are fixedly installed on the surface of the test frame 1. The surfaces of the two double threaded rods 41 are threadedly installed inside the two limit frames 3 to facilitate the double threaded rod 41 to rotate relative to the limit frame 3 by means of threaded connection, and a driving member 40 for the two limit frames 3 to approach or move away synchronously is arranged on one side of the test frame 1.

[0033] Please refer to Figure 3, the driving member 40 includes a driving motor 401 embedded inside the test frame 1. A double-track wheel 402 is installed at the output end of the driving motor 401 and drives the double-track wheel 402 to rotate, so as to adjust the position of the double-track wheel 402 relative to the test frame 1. Guide wheels 403 are fixedly installed at one ends of the two double-threaded rods 41, so that the double-threaded rods 41 and the guide wheels 403 can rotate simultaneously. The double-track wheel 402 is connected to the two guide wheels 403 through a toothed belt 404, so that the double-track wheel 402 can drive the guide wheels 403 to rotate through the toothed belt 404 during rotation, thereby facilitating the guide wheels 403 to rotate through the driving motor 401, the double-track wheel 402, and the toothed belt 404, and further facilitating the guide wheels 403 to rotate as the double-track wheel 402 rotates.

[0034] In this embodiment, the driving motor 401 is started to drive the double-track wheel 402 to rotate. The surface of the double-track wheel 402 is connected to the two guide wheels 403 through two toothed belts 404. Double-threaded rods 41 are fixedly installed at the axles of the two guide wheels 403, thereby controlling the synchronous rotation of the two double-threaded rods 41. The rotation of the two double-threaded rods 41 can cause the two limit frames 3 to approach or move away from each other, achieving a clamping and fixing effect on the TV main board in the horizontal direction of different sizes. At the same time, the air cylinder 602 is started to push the pressing rod 62 to swing, so that the rubber layer ball 7 at one end of the pressing rod 62 presses on the top of the TV main board, providing a pressing force in the vertical direction and fixing the TV main board more firmly.
