[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a PCBA performance testing device, comprising a base 1, which provides basic support for the device and supports all upper components; a connecting column 2 is fixedly connected to the top of the base 1, connecting the base 1 and a top plate 3 to ensure overall structural stability; a top plate 3 is fixedly connected to the top of the connecting column 2, providing an mounting carrier for a fixing mechanism 4; a fixing mechanism 4 is fixedly connected to the bottom of the top plate 3, the fixing mechanism 4 including a cylinder 41, which provides linear driving force; the top of the cylinder 41 is fixedly connected to the bottom of the top plate 3, and a protective cylinder 42 is slidably connected to the bottom of the cylinder 41; a fixing ring 43 is fixedly connected to the bottom of the protective cylinder 42, the fixing ring 43 being used to install a clamping assembly 44; a clamping assembly 44 is fixedly connected to the rear side of the fixing ring 43. The device includes two limiting posts 441, which provide a pivot point for the connecting rod 442. The outer walls of both limiting posts 441 are rotatably connected to the connecting rod 442, which can drive the second limiting post 443 to adjust its position. The outer wall of the connecting rod 442 is rotatably connected to the second limiting post 443, which connects the connecting rod 442 to the connector 444. The rear side of the second limiting post 443 is fixedly connected to the connector 444, which is used to fix the clamp 445. The bottom of the connector 444 is fixedly connected to the clamp 445, which clamps the PCBA through a clamping groove 446. The outer wall of the clamp 445 has a clamping groove 446, which is adapted to the PCBA size. A rubber damping strip is attached to the outer wall of the clamping groove 446 to increase friction and prevent damage to the PCBA during clamping.

[0025] Specifically, the base 1, connecting column 2, and top plate 3 form a stable frame. After startup, the cylinder 41 in the fixing mechanism 4 first provides linear thrust, driving the fixing ring 43 to adjust to the height of the PCBA. Finally, the clamping component 44 on the back of the fixing ring 43 completes the stable clamping according to the PCBA size, avoiding displacement during testing and ensuring that the PCBA performance test data is accurate and reliable.

[0026] Reference Figure 1 , Figure 3 , Figure 4 A detection mechanism 6 is fixed to the front of the connecting column 2. The detection mechanism 6 is used for PCBA performance testing, realizing signal transmission and data acquisition. The bottom of the detection mechanism 6 is fixed to the top of the base 1, which provides support to ensure stable testing. The detection mechanism 6 includes a sliding component 61, which provides sliding tracks for the upper detection plate 62 and the lower detection plate 63. The front of the sliding component 61 is fixed to the rear of the connecting column 2, which ensures its stable installation. The sliding component 61 is slidably connected to the upper detection plate 62, which can move up and down to adapt to the testing. The front of the sliding component 61 is slidably connected to the lower detection plate 63, which is connected to the upper detection plate 62. 2. To achieve synchronous detection of the PCBA top and bottom and improve efficiency, the sliding component 61 includes two symmetrical connecting rods 611 for connecting the fixed plate 612 to the external structure and enhancing strength. The fixed plate 612 is fixed to the rear side of the connecting rods 611, and the fixed plate 612 provides the mounting base for the sliding groove 615 and the sliding column 613. The sliding column 613 is slidably connected to the inner wall of the fixed plate 612, and the sliding column 613 can slide to adjust the position of the detection plate. The inner wall of the fixed plate 612 is provided with a sliding groove 615 to limit the sliding direction of the sliding column 613. The outer wall of the sliding column 613 is fixed with a slider 614, which is embedded in the sliding groove 615 to ensure that the sliding column 613 slides stably and does not detach.

[0027] Specifically, the base 1 supports the testing mechanism 6, and the connecting column 2 fixes the sliding component 61 to ensure stability. In the sliding component 61, the sliding column 613 slides along the sliding groove 615 of the fixed plate 612, driving the upper testing plate 62 and the lower testing plate 63 to adjust up and down to the position suitable for the PCBA. Then, the two testing plates cooperate to synchronously test the upper and lower sides of the PCBA to realize signal transmission and data acquisition and complete the performance test.

[0028] Reference Figure 1 , Figure 3 , Figure 4The PCBA performance testing equipment has a PCBA board 5 slidably connected to the outer wall of the fixing mechanism 4. The PCBA board 5 is the printed circuit board to be tested. When it slides along the outer wall of the fixing mechanism 4, it can be quickly and accurately positioned to the test area, avoiding manual alignment deviation. At the same time, the outer wall of the fixing mechanism 4 provides sliding guidance for the PCBA board 5, ensuring that its movement is stable and does not deviate or bump. Multiple detection contacts 7 are fixedly connected to the adjacent side of the lower detection plate 63 and the upper detection plate 62. The multiple detection contacts 7 are made of metal with excellent conductivity, which can stably transmit detection signals. Moreover, the multiple detection contacts 7 are aligned with the electronic components on the printed circuit board, ensuring that each contact can accurately contact the corresponding electronic component during testing, realizing the synchronous detection of the performance of each component on the PCBA board 5, avoiding missed detections or incorrect detections, and improving the accuracy and efficiency of testing.

[0029] Specifically, the PCBA board 5 slides along the outer wall of the fixing mechanism 4 and is precisely positioned in the test area with the help of the fixing mechanism 4; then the upper detection board 62 and the lower detection board 63 adjust their positions so that the multiple detection contacts 7 on the near side of the two boards are precisely aligned and in contact with the electronic components on the PCBA board 5; the conductive detection contacts 7 stably transmit detection signals and simultaneously collect the performance data of each electronic component to complete the performance test of the PCBA board 5, avoiding alignment deviation and missed detection problems.

[0030] Working principle: During loading, the operator moves the PCBA board 5 to the bottom of the fixing mechanism 4 so that it corresponds with the clamp 445 of the clamping assembly 44. The base 1 supports the equipment, the frame formed by the connecting column 2 and the top plate 3 is stable, and the detection mechanism 6 is ready.

[0031] When the fixing mechanism 4 is activated, the cylinder 41 connected to the top plate 3 drives the bottom clamping assembly 44 to move down. The connecting rod 442 on the outer wall of the first limiting post 441 in the clamping assembly 44 rotates, driving the second limiting post 443 to move. The connecting piece 444 on the rear side of the second limiting post 443 drives the bottom clamp 445 to approach the PCBA board 5, so that the PCBA board 5 is embedded in the clamping groove 446 of the clamp 445. The rubber damping strip on the outer wall of the clamping groove 446 plays an anti-slip and buffering role, thus completing the fixing of the PCBA board 5 and placing it on the outer wall of the fixing mechanism 4.

[0032] The detection mechanism 6, which is connected to the front of the connecting column 2 and the bottom of the base 1, is activated. The sliding component 61 in the detection mechanism 6 is working. The fixed plate 612 behind the connecting rod 611 of the sliding component 61 is stable. The sliding column 613 on the inner wall of the fixed plate 612 and the sliding block 614 on the outer wall slide in the sliding groove 615, which drives the upper detection plate 62 and the lower detection plate 63 to approach each other. The detection contact 7 on the side of the two are close to the electronic components on the PCBA board 5 to achieve detection.

[0033] The sliding component 61 drives the upper detection plate 62 and the lower detection plate 63 to reset, the clamping component 44 releases the PCBA board 5, and the operator takes out the PCBA board 5 to complete the test.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
