Detailed Implementation

[0028] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0030] A vehicle control board testing device, such as Figures 1-6 As shown, the device includes a main body 1 of the testing device, a fixing component 6 inside the main body 1, a detection component 7 on top of the main body 1, and a control module. The fixing component 6 includes a screw 12. Slide grooves are provided on both sides of the upper part of the main body 1. The screw 12 is rotatably mounted in the slide grooves via bearing seats. Two sections of threads with opposite directions are provided on the screw 12. A square detection groove is provided at the top center of the main body 1. Several servo motors 8 are bolted to the back of the main body 1. The servo motors 8 are electrically connected to the control module. The output end of the servo motors 8 is connected to the screw 12. A translation slide 13 is slidably mounted on the two sections of threads with opposite directions on the screw 12. Slide grooves are provided on both sides of the translation slide 13.

[0031] This device is further configured as follows: Figure 5 As shown, the fixing component 6 also includes a double-headed pneumatic telescopic rod 14, which is installed in the middle of the translation slide 13. The double-headed pneumatic telescopic rod 14 is electrically connected to the control module. Fixing seats 15 are bolted to the output ends on both sides of the double-headed pneumatic telescopic rod 14. The top of the fixing seat 15 is provided with a right-angled edge, and a buffer pad 16 is provided on the right-angled edge.

[0032] When the control board is placed in the test slot, the servo motor 8 is driven by the control module to rotate the screw 12 in the forward direction, so that the two translation slides 13 move closer to each other in opposite directions. The control module drives the double-headed pneumatic telescopic rod 14 to fix the four corners of the control board with the fixed seat 15, which is convenient for subsequent testing. The buffer pad 16 can be set to prevent damage to the control board.

[0033] After the test is completed, the control module first drives the double-headed pneumatic telescopic rod 14 to loosen the four corners of the control board by the fixed seat 15. Then, the control module drives the servo motor 8 to rotate the screw 12 in the opposite direction, so that the two translation slides 13 move away from each other in opposite directions.

[0034] Furthermore, there are two servo motors 8; there are two screws 12, which are respectively fixedly connected to the drive shafts of the two servo motors 8.

[0035] The threads of the two screws 12 that are close to each other have opposite directions, and the two servo motors 8 drive the two screws 12 to rotate in opposite directions at the same time.

[0036] In some embodiments, two screws 12 are provided, each controlled by a servo motor 8.

[0037] In one scenario, the threads of the two screws 12 that are close to each other have the same direction, and the two servo motors 8 rotate in the same direction simultaneously to control the rotation of the two screws 12 respectively.

[0038] In another case, refer to Figure 4 The threads of the two screws 12, which are close to each other, turn in opposite directions. The two servo motors 8 rotate simultaneously in opposite directions to control the rotation of the two screws 12 respectively. This method can make the overall stress inside the fixing component 6 zero, reducing the probability of mechanical failure and ensuring more stable clamping of the control board.

[0039] This device is further configured as follows: Figure 1 , Figure 3 As shown, the testing device also includes a first telescopic cylinder 11.

A top plate is bolted to the output end of the first telescopic cylinder 11. The first telescopic cylinder 11 is electrically connected to the control module.

[0040] After the test is completed, the control module drives the first telescopic cylinder 11, causing the top plate on the first telescopic cylinder 11 to push out the control board, making it easier for staff to replace the board and improving the efficiency of the test.

[0041] This device is further configured as follows: Figure 6As shown, the testing device also includes a mounting frame 17, which is mounted on the top of the main body 1 of the testing device by fixing bolts. Several support plates 18 are provided at the corners of the mounting frame 17 to improve the support strength of the mounting frame 17 by utilizing the stability of triangles.

[0042] This device is further configured as follows: Figure 6 As shown, the detection component 7 includes a second telescopic cylinder 19, which is mounted on the top of the mounting frame 17. The mounting frame 17 has a hole through which the output end of the second telescopic cylinder 19 passes. A connecting plate 20 is provided at the output end of the second telescopic cylinder 19, and a mounting hole is provided on the connecting plate 20.

A detection plate 21 is installed at the bottom of the connecting plate 20 by bolts. The detection plate 21 and the detector 23 are connected by a telescopic tube 24. A data transmission line is provided inside the detector 23, and several detection heads 22 are provided at the bottom of the detection plate 21.

[0044] The control module drives the second telescopic cylinder 19 to raise and lower the detection head 22 to contact the electronic components on the control board. The control module then drives the detector 23 to perform an ICT test on the control board to check whether the control board is working properly.

[0045] This device is further configured as follows: Figure 2 As shown, the testing device also includes a connector 9, which is installed on the side of the main body 1 of the testing device and is connected to the detector 23 via a data cable 10.

[0048] Working principle: The circuit board to be tested is placed in the test slot of the main body 1 of the testing device. Then, the control module drives the servo motor 8 and the double-headed pneumatic telescopic rod 14 to fix the circuit board in place by the fixing seat 15. Then, the control module drives the second telescopic cylinder 19 to press the connecting plate 20 tightly against the surface of the circuit board. Then, the control module drives the detector 23 to make the detection head 22 perform an ICT test on the circuit board to check whether the circuit board can work normally. After the test is completed, the control module drives the second telescopic cylinder 19 to raise the detection head 22.
