[0036] Before packaging, capacitors must undergo a withstand voltage test using a tester to evaluate their insulation performance and verify their ability to operate normally at rated voltage or higher without experiencing breakdown, leakage, or short circuit failures. This ensures the capacitors' safe and reliable operation during actual use. However, current testers are inefficient at performing withstand voltage tests on capacitors, making them difficult to meet customer needs.
[0037] To this end, the present invention proposes a high voltage insulation tester 1000, specifically referring to the accompanying drawings of the specification. Figures 1 to 8 shown.
[0038] Reference Figure 1 and Figure 2 As shown, a high voltage insulation tester 1000 according to an embodiment of the present invention is used to perform a withstand voltage test on a capacitor. The capacitor has a first external electrode and a second external electrode, and is mounted on a loading mechanism 2000. Figure 2 As shown, it should be noted that the loading mechanism 2000 includes a loading plate 2100 and a conductive base plate 2200. The loading plate 2100 is provided with a plurality of first through holes 2110, and the plurality of first through holes 2110 are arranged in a matrix, that is, the plurality of first through holes 2110 are arranged in a structure of multiple rows and multiple columns.
[0039] In addition, refer to Figure 3 and Figure 4 As shown, the carrier plate 2100 is fixed to the conductive bottom plate 2200 so that the opening on one side of the first through hole 2110 is closed by the conductive bottom plate 2200. In other words, the opening on the same side of the plurality of first through holes 2110 is closed by the conductive bottom plate 2200. In one embodiment, the carrier plate 2100 is fixed to the conductive bottom plate 2200 by screw connection. In one embodiment, the conductive bottom plate 2200 is a copper plate. Figure 3 and Figure 4 As shown, it should be noted that the capacitor is installed in the first through hole 2110 , and the first external electrode is in contact with the conductive bottom plate 2200 , and the second external electrode is located at the other side opening of the first through hole 2110 .
[0040] Reference Figure 1As shown, a high-voltage insulation tester 1000 according to an embodiment of the present invention includes a housing 100, a conveying mechanism 200, and a detection mechanism 300. The housing 100 is provided with a working plane 110. It should be noted that the working plane 110 can be a vertical plane, a horizontal plane, or an inclined plane, and is not specifically limited here.
[0041] Reference Figure 1 and Figure 3 As shown, it should be noted that the conveying mechanism 200 includes a clamp 210 and a first driving member 220. The clamp 210 is used to clamp the material loading mechanism 2000. Furthermore, the first driving member 220 is mounted on the housing 100 and is capable of driving the clamp 210 to clamp the material loading mechanism 2000 and translate along a first direction on the working plane 110. In one embodiment, the first direction is horizontal.
[0042] Reference Figure 1 and Figure 5 As shown, it should be noted that the detection mechanism 300 includes a mounting frame 310, a test assembly 320, a mounting plate 330, a second drive member 340, and a detector. The mounting frame 310 is mounted to the housing 100. In one embodiment, the mounting frame 310 is mounted to the working plane 110 of the housing 100 using screws. Furthermore, the mounting plate 330 is arranged along a second direction. It should be noted that the second direction is perpendicular to the first direction.
[0043] Reference Figure 5 and Figure 6 As shown, it should be noted that the test assembly 320 is composed of a common needle 321 and a test needle 322. The common needle 321 and the test needle 322 are both mounted on the mounting plate 330, and the common needle 321 and the test needle 322 are arranged along the second direction. In one embodiment, there are multiple common needles 321 and multiple test needles 322. The multiple common needles 321 are first arranged along the second direction, and the multiple test needles 322 are then arranged along the second direction. Figure 6 As shown, it should be noted that there are multiple test components 320, and the multiple test components 320 are arranged at intervals along the first direction.
[0044] Reference Figure 5As shown, the second driving member 340 is installed on the mounting frame 310 and is capable of driving the mounting plate 330, thereby driving the common pin 321 and the test pin 322 on the mounting plate 330 to move, so that the common pin 321 abuts against the conductive base plate 2200 and the test pin 322 abuts against the second outer electrode of the capacitor in the first through hole 2110. In one embodiment, there are multiple common pins 321 and multiple test pins 322. In this case, the multiple common pins 321 all abut against the conductive base plate 2200, and each test pin 322 abuts against the second outer electrode of the capacitor in the corresponding first through hole 2110. In one implementation, the second driving member 340 is a cylinder. It is understandable that the cylinder can stably drive the mounting plate 330 to move, ensuring that the test work is successfully completed.
[0045] It should be noted that the detector is electrically connected to the test assembly 320. It is understandable that the first driving member 220 drives the fixture 210 to drive the loading mechanism 2000 to translate. When the loading mechanism 2000 moves to the working area of the detection mechanism 300, the second driving member 340 drives the mounting plate 330 to make the common pin 321 of the test assembly 320 abut against the conductive base plate 2200 and the test pin 322 abut against the second external electrode, thereby transmitting the electrical signal to the detector to realize the detection of the capacitance. At the same time, since the test assembly 320 is provided with multiple test assemblies 320, the multiple test assemblies 320 are spaced apart along the first direction, and the multiple first through holes 2110 for mounting capacitors are arranged in a matrix, each test assembly 320 can test the capacitance in a column of the first through holes 2110, that is, the detection mechanism 300 can test the capacitance in multiple columns of the first through holes 2110 at a time, thereby improving the test efficiency and meeting customer needs.
[0046] Reference Figure 3 and Figure 7 As shown, in a high-voltage insulation testing machine 1000 according to an embodiment of the present invention, the first driving member 220 includes a motor 221, a lead screw 222 and a slider 223. The motor 221 is mounted on the housing 100 and is driven and connected to the lead screw 222. In one embodiment, the motor 221 is mounted on the housing 100 by a threaded connection. It should be noted that the lead screw 222 is arranged along the first direction. In addition, the lead screw 222 is driven and connected to the slider 223 to drive the slider 223 to translate along the first direction. At the same time, the slider 223 is connected to the fixture 210 to drive the fixture 210 to translate along the first direction. It can be understood that the motor 221 can convert the rotational driving force into the translational driving force through the lead screw 222, thereby driving the slider 223 to drive the fixture 210 to translate, thereby realizing the translation of the loading mechanism 2000 on the working plane 110.
[0047] Reference Figure 2 and Figure 4As shown, in a high-voltage insulation tester 1000 according to one embodiment of the present invention, the clamp 210 includes a support plate 211 and multiple spring plates 212. The support plate 211 is drivably connected to a first drive member 220, meaning that the first drive member 220 can drive the support plate 211 to translate in a first direction. Furthermore, the support plate 211 is provided with multiple support protrusions 2111 for supporting the loading mechanism 2000, and each spring plate 212 is mounted on a support protrusion 2111 to clamp the loading mechanism 2000. It will be appreciated that this arrangement enables a secure clamping of the loading mechanism 2000. In one embodiment, the edges of the conductive base plate 2200 abut against the multiple support protrusions 2111, and the multiple spring plates 212 abut against a surface of the conductive base plate 2200 to achieve clamping. It should be noted that the spring plates 212 can be mounted on the support protrusions 2111 by means of threaded connections, etc., which are not specifically limited herein.
[0048] Reference Figure 2 As shown, in one embodiment, the support plate 211 is provided with a positioning post 2112, and the loading mechanism 2000 is provided with a positioning slot 2220. It should be noted that the positioning post 2112 cooperates with the positioning slot 2220, so that the loading mechanism 2000 is positioned and placed on the support protrusion 2111 via the positioning slot 2220 and the positioning post 2112. It will be appreciated that this arrangement enables rapid placement of the loading mechanism 2000. In one embodiment, the positioning post 2112 is cylindrical. In another embodiment, the positioning slot 2220 is provided on the conductive base plate 2200.
[0049] Reference Figure 4 and Figure 5 As shown, in one embodiment, the working plane 110 is at an angle to the horizontal plane. That is to say, the working plane 110 is not a horizontal plane. It is understandable that the above-mentioned arrangement makes it more convenient for workers to place the loading mechanism 2000 on the conveying mechanism 200. In addition, the housing 100 is provided with a guide groove 150, and the upper groove wall of the guide groove 150 is provided with a through groove 151. It should be noted that the support plate 211 is slidably connected to the guide groove 150 and is provided with a connecting plate body 2113, which passes through the through groove 151 and is driven and connected to the first driving member 220. It is understandable that the guide groove 150 plays a guiding role for the support plate 211, and setting the through groove 151 on the upper groove wall can prevent the capacitor from accidentally falling off during transportation and being adjusted into the through groove 151. In one embodiment, the connecting plate body 2113 is connected to the slider 223. When the motor 221 and the lead screw 222 drive the slider 223 to translate, the slider 223 drives the support plate 211 to translate through the connecting plate body 2113, thereby realizing the translation of the loading mechanism 2000.
[0050] Reference Figure 1 and Figure 8As shown, a high voltage insulation tester 1000 according to an embodiment of the present invention further includes a bin separation mechanism 400. The bin separation mechanism 400 includes a qualified bin 410, an unqualified bin 420, a recovery bin 430 and an air blow hole plate 440. The qualified bin 410, the unqualified bin 420, the recovery bin 430 and the air blow hole plate 440 are all installed on the housing 100. It should be noted that the qualified bin 410, the unqualified bin 420 and the recovery bin 430 are arranged along the first direction. Figure 4 As shown, the conductive bottom plate 2200 is provided with a plurality of second through holes 2210 , and the plurality of second through holes 2210 are connected to the plurality of first through holes 2110 in a one-to-one correspondence.
[0051] It should be noted that the air blowing plate 440 can blow air toward the second through hole 2210 to blow the capacitor in the first through hole 2110 to the qualified bin 410 or the unqualified bin 420 or the recovery bin 430. It should be noted that after the detector tests the capacitor, the air blowing plate 440 blows air in a targeted manner to blow the qualified capacitor to the qualified bin 410, the unqualified capacitor to the unqualified bin 420, and finally the unblown capacitor to the recovery bin 430. It should be noted that the capacitor in the recovery bin 430 needs to be reinstalled in the loading mechanism 2000 and then undergo a withstand voltage test. It can be understood that through the above-mentioned arrangement, the classification of capacitors can be achieved during blanking, simplifying subsequent processes.
[0052] Continue to refer to Figure 1 and Figure 8 As shown, the qualified warehouse 410 includes a first guide warehouse channel 411 and a first warehouse body 412. Among them, the first guide warehouse channel 411 is fixed to the shell 100, and plays a guiding role in the blown-out capacitors. In addition, the first warehouse body 412 is communicated with the first guide warehouse channel 411 and can be detachably installed on the first guide warehouse channel 411. It can be understood that the first warehouse body 412 plays the role of storing capacitors. Qualified capacitors are blown out and enter the first warehouse body 412 under the guidance of the first guide warehouse channel 411. After all the qualified capacitors are blown out, the first warehouse body 412 can be disassembled and taken out to complete the unloading of qualified capacitors.

In addition, the second warehouse body 422 is communicated with the second guide warehouse channel 421 and can be detachably installed on the second guide warehouse channel 421. It can be understood that the second warehouse body 422 plays the role of storing capacitors. The unqualified capacitors are blown out and enter the second warehouse body 422 under the guidance of the second guide warehouse channel 421. After all the unqualified capacitors are blown out, the second warehouse body 422 can be disassembled and taken out to complete the unloading of the unqualified capacitors.
[0055] Reference Figure 8 As shown, in one embodiment, the second guide channel 421 is provided with a third chute 4211, and the housing 100 is provided with a fourth chute 130 parallel to the third chute 4211. It should be noted that one end of the second bin body 422 is slidably connected to the third chute 4211, and the other end, facing away from the second bin body 422, is slidably connected to the fourth chute 130. It will be appreciated that, through this arrangement, the second bin body 422 can slide out quickly during disassembly, thereby increasing the unloading speed of unqualified capacitors.
[0056] Continue to refer to Figure 1 and Figure 8 As shown, the recycling bin 430 includes a third guide bin channel 431 and a third bin body 432. The third guide bin channel 431 is fixed to the shell 100 and guides the blown-out capacitors. In addition, the third bin body 432 is connected to the third guide bin channel 431 and can be detachably mounted on the third guide bin channel 431. It can be understood that the third bin body 432 serves to store capacitors. The capacitors to be recycled are blown out and enter the third bin body 432 under the guidance of the third guide bin channel 431. After all the capacitors to be recycled are blown out, the third bin body 432 can be disassembled and the unloading of the capacitors to be recycled is completed.
[0057] Reference Figure 8 As shown, in one embodiment, the third guide channel 431 is provided with a fifth chute 4311, and the housing 100 is provided with a sixth chute 140 parallel to the fifth chute 4311. It should be noted that one end of the third bin body 432 is slidably connected to the fifth chute 4311, and the other end, facing away from the third bin body 432, is slidably connected to the sixth chute 140. It will be appreciated that this arrangement allows the third bin body 432 to slide out quickly during disassembly, thereby increasing the unloading speed of the capacitors to be recycled.
