[0002] In the process of circuit board processing, aluminum substrates need to be subjected to high voltage detection to ensure their insulation performance. Currently, batch detection is usually adopted: a large-size substrate composed of multiple small aluminum substrates is manually fed into a test machine, the test machine is internally provided with multiple probes corresponding to the test points of each small substrate, and the detection of all units on the whole large substrate can be completed at the same time, thereby improving the test efficiency.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Example 1: A batch withstand voltage testing device for aluminum substrates, such as... Figures 1-9 As shown, it includes a workbench 1, a receiving plate 2, and a connecting plate 3; the receiving plate 2 is bolted to the workbench 1; the connecting plate 3 is fixed to the workbench 1; it also includes telescopic cylinders 4, a box body 5, probes 6, a cover plate 7, partitions 8, and a limiting assembly; two telescopic cylinders 4 are bolted to the connecting plate 3; the telescopic ends of all telescopic cylinders 4 are fixed to the box body 5; several probes 6 are fixed to the box body 5, and the probes 6 are made of alloy material; the cover plate 7 is detachably connected to the upper side of the box body 5; several partitions 8 are movably connected to the inner side of the box body 5; the width of the partitions 8 is arranged in an increasing order; a sandwich 91 is formed between each pair of corresponding partitions 8; the limiting assembly is connected to the box body 5.

[0017] The limiting assembly includes a locking block 201, a locking rod 202, and a locking block 203. The locking block 201 is connected to the box 5. The locking block 201 can be made of metal or plastic. Several locking rods 202 are bolted to the locking block 201. The locking block 203 is bolted to the locking block 201 and is bolted to the locking rods 202. Several grooves 92 are provided on the locking block 201, the locking rods 202, and the locking block 203. The wire passes through the grooves 92 and is limited by the grooves 92.

[0018] It also includes auxiliary components, including a connecting plate 204 and a support block 208; a connecting plate 204 is bolted to the left and right sides of the inner side of the box 5; a support block 208 is bolted to each connecting plate 204, and the support block 208 contacts the corresponding partition 8; each partition 8 is provided with two rotating shafts 93; the rotating shafts 93 of the partition 8 are rotatably connected to the connecting plate 204; each partition 8 is provided with a flange 94, and adjacent flanges 94 are in contact; each partition 8 is provided with several grooves 95, and the grooves 95 are aligned with the corresponding probes 6.

[0019] It also includes a combing assembly, which includes multi-stage telescopic rods 205 and L-shaped blocks 206; locking block 201 is in contact with the box body 5; four multi-stage telescopic rods 205 are fixedly connected to the box body 5, and the telescopic ends of the multi-stage telescopic rods 205 are fixedly connected to locking block 201; two L-shaped blocks 206 are slidably connected to the box body 5; two fixing holes are opened on locking block 201, and the ends of the L-shaped blocks 206 are inserted into the corresponding fixing holes to fix locking block 201.

[0020] During assembly and wiring, the cover plate 7 is manually removed to expose the partition plate 8, and then the locking rod 202 and locking block 203 are disassembled, as follows. Figure 6 and Figure 7As shown, the interlayer 91 is counted from bottom to top, the probes 6 are counted from the side closest to the support block 208, and the locking rod 202 is counted from bottom to top. The other partitions 8 above the first row of partitions 8 are flipped upwards, causing the partitions 8 to rotate around the pivot 93, thus exposing the first row of partitions 8. Then, a wire is manually connected to the probes 6, and the wire is laid on the upper side of the first row of partitions 8, passing through the groove 95 of the first row of partitions 8, and then through the groove 92 on the locking block 201. Finally, the locking rod 202 is inserted into the locking block 201. 1. The wire is then positioned in the groove 92. The second row of partitions 8 is then manually flipped back to its original position, so that the end of the second row of partitions 8 away from the pivot 93 rests on the flange 94 of the first row of partitions 8. At this time, a sandwich 91 is formed between the first row of partitions 8 and the second row of partitions 8, and the wire on the first row of probes 6 passes through this sandwich 91. Then, another wire is manually connected to the second row of probes 6, and the wire is then placed on the upper side of the second row of partitions 8 and passed through the groove 95 of the second row of partitions 8, and then through the groove 92 on the upper side of the first row of locking rods 202. Next, insert the second row of locking rods 202 onto the upper side of the first row of locking rods 202, positioning the wire in the corresponding groove 92. Then, manually flip the third row of partitions 8 back to its original position, so that the end of the third row of partitions 8 away from the pivot 93 rests on the flange 94 of the second row of partitions 8. At this time, a sandwich 91 is formed between the second row of partitions 8 and the third row of partitions 8, and the wire on the second row of probes 6 passes through this sandwich 91. Repeat this process to complete the wire installation operation. After installing the last row of wires, manually insert the second locking block 203 onto the upper side of the top locking rod 202. Then, the locking block 201, locking rod 202, and locking block 203 are fixed with bolts, and the cover plate 7 is installed back in its original position to complete the assembly and wiring operation. After that, all wire ends are connected to the external testing machine. During the test, the large-size substrate composed of multiple small aluminum substrates is placed on the receiving plate 2 by the operator. The telescopic cylinder 4 is activated, and the telescopic cylinder 4 drives the box 5 and its parts to move downward, so that the probe 6 moves downward to contact the test position of the aluminum substrate. At this time, the external testing machine discharges the aluminum substrate through the wires and the probe 6, thereby performing a batch withstand voltage test on the aluminum substrate.

[0021] When a short circuit or open circuit occurs in the wire, assuming the wire on the third row of probes 6 is faulty, the cover plate 7 is opened manually, and then the other partitions 8 above the third row of partitions 8 are flipped upwards to expose the third row of partitions 8, thereby exposing the third row of probes 6 and the wires on them. At this time, the corresponding wire end is detached from the probe 6, and then the other end of the wire is pulled to pull the wire out of groove 2 95 and groove 1 92. The wire is then removed, and the new wire end is connected to the external testing machine. At this time, it is not necessary to disassemble locking block 1 201, locking rod 202, and locking block 2 203; the wire can be directly connected. The other end passes through the corresponding groove 92 and then through the corresponding groove 95, moving it to the upper side of the third row of partitions 8. The wire is then connected to the corresponding probe 6. The other partitions 8 above the third row of partitions 8 are flipped back to their original positions, and the cover plate 7 is installed back to its original position, completing the wire replacement operation. In use, the wires are separated by the partitions 8 with increasing widths. When a wire fails, the location of the faulty wire can be quickly determined and removed by the operator. This avoids the difficulty in locating and replacing faulty wires caused by the complex wiring harnesses of existing equipment, thus improving the convenience of manual operation.

[0022] During the inspection, the telescopic cylinder 4 drives the box 5 to move up and down reciprocally. Even with the groove 92 limiting each wire, the wires on the outside of the box 5 may still cross and overlap due to long-term shaking. When replacing the wires, the manual needs to flip the partition 8 upwards. At this time, the partition 8 will move the wires together, thereby pulling the wires on the outside of the box 5 inwards. If the wires on the outside of the box 5 are cross-over, the resistance when pulling the wires will be greatly increased, making it difficult for the partition 8 to open normally. Therefore, before replacing the wires, the manual moves the L-shaped block 206 away from the locking block 201, so that the L-shaped block 206 stops fixing the locking block 201. Then, the manual pulls the locking block 201 away from the box 5. The locking block 201 drives the locking rod 202 and the second locking block 203 to move simultaneously, and stretches the multi-stage telescopic rod 205, thereby passing through the locking block. Locking blocks 201, 202, and 203 work together to allow groove 92 to disperse the crossed wires. Then, lock blocks 201, 202, and 203 are pushed back to their original positions, and L-shaped block 206 is used to re-fix lock block 201. After that, the wire replacement operation is performed. When the partition 8 is manually flipped, the partition 8 moves the dispersed wires towards the inside of the box 5 without jamming. After the replacement is completed, when the partition 8 is manually flipped back to its original position, the wires are pulled outwards to ensure that the wires distributed inside the box 5 are straight. In use, lock blocks 201, 202, and 203, which are used to limit the wires, can also disperse the wires outside the box 5, so that when the partition 8 is flipped, the partition 8 can move the dispersed wires towards the inside of the box 5 without jamming.

[0023] Example 2, based on Example 1, such as Figure 9 and Figure 10 As shown, it also includes rubber blocks 207; each partition 8 has several grooves 96, which are aligned with the corresponding probes 6; each partition 8 has several rubber blocks 207 fixedly attached to it, and the rubber blocks 207 are located inside the corresponding grooves 96, so that the wires are fixed by the rubber blocks 207.

[0024] Each groove 96 has several beveled surfaces 97 on both sides of the opening. The beveled surfaces 97 guide the wire, making it easier for the wire to be inserted into the rubber block 207.

[0025] The cover plate 7 is equipped with a handle, which makes it easier to open the cover plate 7 manually by applying force.

[0026] During the replacement process, the partition 8, during its flipping motion, applies friction to the wires on it. This friction acts at the connection point between the wires and probe 6, potentially interfering with the stability of the connection and thus disrupting subsequent testing. Therefore, a rubber block 207 is installed on the partition 8. When installing the wires, the ends are fixed to the probe 6, then the wires are inserted into the rubber block 207, and finally, the wires are placed on the upper side of the partition 8. At this point, the rubber block 207, through its elastic deformation, presses the wires firmly and reliably. During the flipping process of the partition 8, because the wires are effectively fixed at the rubber block 207, the friction generated by the partition 8 on the wires mainly acts on the pressing area of ​​the rubber block 207, rather than being directly transmitted to the connection point between the wires and probe 6. The effect of the friction is absorbed and dispersed by the rubber block 207, thus preventing the connection point from being loosened due to direct force.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
