Description

Technical Field

[0001] This utility model relates to the field of testing device technology, and more specifically to a PCBA testing device. Background Technology

[0002] With industrial development, integration is increasing, and products are becoming smaller and more modular, placing higher demands on the reliability of each module. Therefore, PCBA boards undergo rigorous and comprehensive reliability testing before assembly and shipment to meet product quality requirements.

[0003] Common PCBA testing equipment is used to test the function of PCBA. The working process is as follows: First, turn on the PCBA testing equipment, then place the PCBA board to be tested on the testing table, clamp it with the fixture, and move the PCBA testing equipment downward through the lifting mechanism so that the probes used for testing come into contact with the PCBA board, thereby testing the PCBA board.

[0004] In existing technologies, the fixtures used for clamping and fixing can only position PCBA boards of one shape. When the production line needs to switch to other types of PCBA boards, the fixtures need to be changed. This increases production line downtime, reduces production efficiency, and requires the storage and management of a large number of specialized fixtures, which occupies additional production space. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a PCBA testing device to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a PCBA testing device, including a workbench, a testing platform installed in the middle of the top of the workbench, a testing device installed on the back of the top of the workbench, clamping cylinders installed on both sides of the top of the workbench, a moving component installed on the piston end of the clamping cylinder, and clamping fixtures installed around the outer perimeter of the moving component. The moving component includes a fixed frame, and a mounting post is movably sleeved on the top of the inner side of the fixed frame. The clamping fixture includes a fixed block fixedly connected to the top of the outer side of the mounting post. A pressure sensor is installed on the surface of the fixed block, and a mounting block is installed on the other end of the pressure sensor. A mounting frame is installed on the end of the mounting block away from the pressure sensor, and a clamping element is fixedly connected to the surface of the mounting frame away from the mounting block.

[0007] Furthermore, the top of the fixed frame is provided with an installation groove, and the inner side of the installation groove is provided with fixing grooves on all four sides.

[0008] Furthermore, a T-shaped block is fixedly connected to the bottom of the fixed frame, and sliding grooves are provided on both sides of the top of the workbench, with the sliding grooves slidably connected to the T-shaped block.

[0009] Furthermore, a first movable hole is provided on the side of the mounting column, a first spring is fixedly connected to the middle of the inner side of the first movable hole, and a first pin is fixedly connected to both ends of the first spring. Movable grooves are provided on both sides of the top of the inner wall of the first movable hole, and a control rod is fixedly connected to the top of the first pin.

[0010] Furthermore, a positioning block is fixedly connected to the inner wall of the mounting frame, and a fixing hole is provided on the outer side of the mounting frame.

[0011] Furthermore, a positioning groove is provided on the outer side of the mounting block, a second movable hole is provided on the inner side of the mounting block, a connecting groove is provided on the top of the inner wall of the second movable hole, a second spring is fixedly connected to the middle of the inner side of the positioning groove, a second pin is fixedly connected to both ends of the second spring, and a control block is fixedly connected to the top of the second pin.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model, by providing a fixed frame and mounting posts, allows for the rotation of the mounting post when different types of PCBA boards are required. Pressing the control lever inward causes the first pin to retract into the inner side of the first movable hole, thereby separating the first pin from the inner side of the fixed groove. Four clamping fixtures are provided on the outer side of the moving assembly, allowing the corresponding clamping fixture to rotate towards the inspection table. Releasing the control lever causes the first pin to extend into the corresponding fixed groove under the elastic force of the first spring, thus fixing the mounting post and adjusting the clamping fixtures to match the shape of the PCBA board to be inspected.

[0014] 2. This utility model, by providing a clamping fixture, presses the control block in a direction that brings them closer together, causing the second pin to retract into the inner side of the second movable hole. Then, the second pin separates from the inner side of the fixed hole. The mounting frame is then moved vertically upwards to remove the original clamping component. The new mounting frame is then placed vertically downwards on the outer side of the mounting block. The inclined surface of the second pin is squeezed into the inner side of the second movable hole by the mounting frame. After the mounting frame is in place, under the action of the second spring, the second pin inserts into the interior of the fixed hole, completing the installation of the new mounting frame and clamping component.

[0025] In this embodiment, after the PCBA board is placed on top of the testing table 101, the clamping cylinder 2 pushes the moving assembly 3 to move towards each other, so that the clamping member 405 can clamp and fix the PCBA board. When different types of PCBA boards are needed, the control rod 335 is pressed inward, thereby driving the first pin rod 333 to retract into the inner side of the first movable hole 331, and then the first pin rod 333 separates from the inner side of the fixing groove 311, so that the mounting post 303 can be rotated. Four clamping fixtures 4 are provided on the outer side of the moving assembly 3, which can rotate the corresponding clamping fixture 4 to face the testing table 101.

Then, the new mounting frame 404 is vertically placed on the outer side of the mounting block 403. The inclined surface of the second pin rod 435 is squeezed into the inner side of the second movable hole 433 by the mounting frame 404. After the mounting frame 404 is installed in place, under the action of the second spring 434, the second pin rod 435 is inserted into the interior of the fixing hole 441, completing the installation of the new mounting frame 404 and the clamping parts 405.
