For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] like Figure 1 As shown, an embodiment of the present invention relates to a capacitor testing system, comprising a conveying device 100, a posture correction device 200, a flipping device 300, a transition device 400, a handling device 500, a capacitor testing device 600 and a controller (not shown), wherein the conveying device 100, the posture correction device 200, the flipping device 300, the transition device 400, the handling device 500 and the capacitor testing device 600 are all electrically connected to the controller, and the controller is used to control the actions of the conveying device 100, the posture correction device 200, the flipping device 300, the transition device 400, the handling device 500 and the capacitor testing device 600.

[0052] like Figures 1 to 3 as well as Figure 7 As shown, the conveying device 100 is used to convey the capacitor 1000 to the waiting position 10; the posture correction device 200 is used to grab the capacitor 1000 from the waiting position 10 and correct the posture of the capacitor 1000; the flipping device 300 is used to flip the corrected capacitor 1000 and transfer it to the transition device 400; the transport device 500 is used to transport the capacitor 1000 on the transition device 400 to the capacitor testing device 600; the capacitor testing device 600 is used to test the capacitor 1000.

[0053] like Figure 1 , Figure 3 As shown, the conveying device 100 is a conveyor belt mechanism, and the conveying device 100 is arranged upstream of the posture correction device 200. The conveying device 100 is used to transport the capacitor 1000 to the waiting position 10, wherein the waiting position 10 is located at the end of the conveying device 100. When the previous capacitor 1000 located at the waiting position 10 is taken away, the next capacitor 1000 can be transported to the waiting position 10 under the action of the conveying device 100.

[0054] like Figure 2 , Figure 3 As shown, the posture correction device 200 includes a support table 210, a moving mechanism 220, a visual inspection mechanism 230, and a posture correction mechanism 240. The support table 210 is used to support the capacitor 1000 located at the visual inspection position 20 and the posture correction position 30, the moving mechanism 220 can move the capacitor 1000 from the waiting position 10 to the visual inspection position 20, the posture correction position 30, and the defective product rejection position 40 in sequence, the visual inspection mechanism 230 is used to obtain an image of the capacitor 1000 located at the visual inspection position 20, and the posture correction mechanism 240 is used to correct the posture of the capacitor 1000 located at the posture correction position 30.

[0055] like Figure 7 Specifically, the upper end of the capacitor 1000 located at the visual inspection position 20 has a positive terminal 1100 and a negative terminal 1200. Please continue to refer to Figure 2 and Figure 3 After the visual inspection mechanism 230 obtains the image of the capacitor 1000 located at the visual inspection position 20, the visual inspection mechanism 230 transmits the image to the controller, and the controller can obtain the deflection angle of the capacitor 1000 according to the positions of the positive terminal 1100 and the negative terminal 1200 of the capacitor 1000 in the image. After the capacitor 1000 located at the visual inspection position 20 is brought to the posture correction position 30 by the moving mechanism 220, the controller can control the posture correction mechanism 240 to correct the posture of the capacitor 1000 located at the posture correction position 30 according to the deflection angle of the capacitor 1000.

[0056] For example, Figure 8The capacitor 1000 on the left side of the figure is the capacitor 1000 to be corrected, and the capacitor 1000 on the right side is the capacitor 1000 that has been corrected. The deflection angle of the capacitor 1000 on the left side is α. After the visual detection mechanism 230 obtains the capacitor 1000 located at the visual detection position 20, the visual detection mechanism 230 transmits the image to the controller. The controller can know that the deflection angle of the capacitor 1000 is α according to the positions of the positive terminal 1100 and the negative terminal 1200 of the capacitor 1000 in the image. When the capacitor 1000 is brought to the posture correction position 30 by the moving mechanism 220, the controller can control the posture correction mechanism 240 to correct the posture of the capacitor 1000 located at the posture correction position 30, so that the capacitor 1000 is rotated by α degrees.

[0057] like Figure 2 , Figure 3 As shown, the moving mechanism 220 includes a translation driving member 221, a first clamping assembly 222, a second clamping assembly 223 and a third clamping assembly 224. The translation driving member 221 is used to drive the first clamping assembly 222, the second clamping assembly 223 and the third clamping assembly 224 to move simultaneously, so that when the first clamping assembly 222 is located at a position capable of clamping the capacitor 1000 located at the waiting position 10, the second clamping assembly 223 is located at a position capable of clamping the capacitor 1000 located at the visual inspection position 20, and the third clamping assembly 224 is located at a position capable of clamping the capacitor 1000 located at the posture correction position 30. When the first clamping assembly 222 is located at a position capable of clamping the capacitor 1000 located at the visual inspection position 20, the second clamping assembly 223 is located at a position capable of clamping the capacitor 1000 located at the posture correction position 30, and the third clamping assembly 224 is located at a position capable of clamping the capacitor 1000 located at the defective product rejection position 40.

[0058] After the first capacitor located at the waiting position 10 is clamped by the first clamping assembly 222, the translation driving member 221 drives the first clamping assembly 222, the second clamping assembly 223 and the third clamping assembly 224 to move forward at the same time, so that the first clamping assembly 222 brings the first capacitor to the visual inspection position 20, so that the visual inspection mechanism 230 obtains an image of the first capacitor; then, the first clamping assembly 222 releases the first capacitor; then, the translation driving member 221 drives the first clamping assembly 222, the second clamping assembly 223 and the third clamping assembly 224 to move backward at the same time, so that the first clamping assembly 222 moves to a position where it can clamp the second capacitor located at the waiting position 10, and the second clamping assembly 223 moves to the third clamping assembly 224. Component 223 moves to a position where it can clamp the first capacitor located at the visual detection position 20; then, the first clamping component 222 clamps the second capacitor, and the second clamping component 223 clamps the first capacitor; then, the translation drive 221 drives the first clamping component 222, the second clamping component 223 and the third clamping component 224 to move forward at the same time, so that the second clamping component 223 brings the first capacitor to the posture correction position 30, and the first clamping component 222 brings the second capacitor to the visual detection position 20, so that the visual detection mechanism 230 obtains an image of the second capacitor; then, the first clamping component 222 releases the second capacitor, and the second clamping component 223 releases the first capacitor, and the posture correction The mechanism 240 then corrects the posture of the first capacitor; thereafter, the translation drive 221 drives the first clamping component 222, the second clamping component 223 and the third clamping component 224 to move backward at the same time, so that the first clamping component 222 moves to a position capable of clamping the third capacitor located at the waiting position 10, the second clamping component 223 moves to a position capable of clamping the second capacitor located at the visual detection position 20, and the third clamping component 224 moves to a position capable of clamping the first capacitor located at the posture correction position 30; thereafter, the first clamping component 222 clamps the third capacitor, the second clamping component 223 clamps the second capacitor, and the third clamping component 224 clamps the first capacitor; thereafter, the translation drive 221 drives the first clamping component 222, the second clamping component 223 and the third clamping component 224 to move backward simultaneously, so that the first clamping component 222 moves to a position capable of clamping the third capacitor located at the waiting position 10, the second clamping component 223 moves to a position capable of clamping the second capacitor located at the visual detection position 20, and the third clamping component 224 moves to a position capable of clamping the first capacitor located at the posture correction position 30; thereafter, the translation drive 221 drives the first clamping component 222, the second clamping component 223 and the third clamping component 224 to clamp the first capacitor; thereafter, the translation drive 221 drives the first clamping component 222, the second clamping component 223 and the third clamping component 224 to move backward simultaneously, so that the first clamping component 222 moves to a position capable of clamping the third capacitor located at the waiting position 10, the second clamping component 223 moves to a position capable of clamping the second capacitor located at the visual detection position 20, and the third clamping component 224 moves to a position capable of clamp The driving member 221 then drives the first clamping component 222, the second clamping component 223 and the third clamping component 224 to move forward at the same time, so that the third clamping component 224 brings the first capacitor to the defective product rejection position 40, the second clamping component 223 brings the second capacitor to the posture correction position 30, and the first clamping component 222 brings the third capacitor to the visual inspection position 20, so that the visual inspection mechanism 230 obtains an image of the third capacitor; thereafter, the first clamping component 222 releases the third capacitor, the second clamping component 223 releases the second capacitor, the posture correction mechanism 240 corrects the posture of the second capacitor located at the posture correction position 30, and the third clamping component 224 releases the first capacitor.

[0059] In the posture correction device 200 of the present invention, after the previous capacitor 1000 completes posture correction, the next capacitor 1000 can be immediately sent to the posture correction position 30, and the waiting time is short. Compared with the traditional solution, the manipulator first moves the capacitor 1000 from the waiting position 10 to the visual detection position 20 and the posture correction position 30 in sequence, and then the manipulator returns and then sends the next capacitor 1000 located at the waiting position 10 to the visual detection position 20 and the posture correction position 30 in sequence, which has higher detection efficiency.

[0060] like Figure 3 As shown, the moving mechanism 220 also includes a mounting seat (not shown) that is drivingly connected to the translation driving member 221, and the first clamping assembly 222, the second clamping assembly 223 and the third clamping assembly 224 are all arranged on the mounting seat. In this way, the translation driving member 221 can simultaneously drive the first clamping assembly 222, the second clamping assembly 223 and the third clamping assembly 224 to move.

[0061] The translation driving member 221 is a cylinder, and the first clamping assembly 222, the second clamping assembly 223 and / or the third clamping assembly 224 are all clamps capable of clamping or loosening the capacitor 1000. Figure 1 and Figure 3 The first clamping assembly 222 is located on a side of the second clamping assembly 223 close to the conveying device 100 , and the second clamping assembly 223 is located on a side of the third clamping assembly 224 close to the conveying device 100 .

[0062] like Figures 2 to 4 As shown, in one embodiment, the visual inspection mechanism 230 includes a camera 231 and an annular fill light. The camera 231 is disposed directly above the visual inspection position 20 , and the annular fill light is disposed between the camera 231 and the visual inspection position 20 .

[0063] Specifically, the camera 231 is a CCD (charge coupled device) camera, and the camera 231 is used to take a picture of the capacitor 1000 located at the visual detection position 20, so as to obtain a pattern of the capacitor 1000. The annular fill light is an annular light source, and the annular fill light can provide fill light, thereby improving the shooting quality.

[0064] like Figure 4 As shown, in one embodiment, the posture correction device 200 further includes a limiting unit 232, and the limiting unit 232 is used to limit the capacitor 1000 located at the visual detection position 20. In this way, the capacitor 1000 can be prevented from shaking and affecting the shooting effect.

[0065] Specifically, the limiting unit 232 is a clamp that can clamp or release the capacitor 1000. When the capacitor 1000 is located at the visual detection position 20, the limiting unit 232 can clamp the capacitor 1000. When the camera 231 completes shooting, the limiting unit 232 can release the capacitor 1000.

[0066] like Figure 4 As shown, in one embodiment, the posture correction mechanism 240 includes a rotating driving member 241 and a first clamp 242 drivingly connected to the rotating driving member 241, and the first clamp 242 is used to clamp the capacitor 1000 located at the posture correction position 30. After the first clamp 242 clamps the capacitor 1000, the rotating driving member 241 can drive the third clamping unit 6123 to rotate, thereby driving the capacitor 1000 to rotate, so that the posture of the capacitor 1000 is adjusted.

[0067] The rotating driving member 241 is a motor; the first clamp 242 can clamp or release the capacitor 1000 .

[0068] like Figure 5 As shown, in one embodiment, the capacitor testing system also includes a good product support device 700 electrically connected to the controller, and the good product support device 700 includes an extended state and a retracted state. When the good product support device 700 is in the extended state, it can support the capacitor 1000 located at the defective product rejection position 40, and when the good product support device 700 is in the retracted state, it avoids the capacitor 1000 located at the defective product rejection position 40.

[0069] Combination Figure 2 , Figure 3 and Figure 5When the capacitor 1000 is located at the visual inspection position 20, the visual inspection mechanism 230 can obtain an image of the capacitor 1000, and then transmit the image to the controller. The controller can determine whether the capacitor 1000 is a good product based on the image of the capacitor 1000. When the capacitor 1000 is a good product, the controller controls the good product support device 700 to switch to the extended state. In this way, when the moving mechanism 220 transports the capacitor 1000 to the defective product rejection position 40, the good product support device 700 can support the capacitor 1000 to prevent the capacitor 1000 from falling. After that, the controller controls the flipping device 300 to flip the capacitor 1000 supported by the good product support device 700 and transport it to the transition position 50. When the controller determines that the capacitor 1000 is a defective product, the controller controls the good product support device 700 to switch to the retracted state. In this way, when the moving mechanism 220 transports the capacitor 1000 to the defective product rejection position 40, the capacitor 1000 falls due to lack of support. In this way, the defective products can be rejected. Furthermore, the defective product rejection device of the present embodiment can automatically reject defective products without the need for manual rejection of defective products, thereby reducing the labor intensity of workers.

[0070] It should be noted that when the visual inspection mechanism 230 obtains an image of the capacitor 1000 and transmits the image to the controller, the controller can determine whether the positive terminal 1100 and / or the negative terminal 1200 of the capacitor 1000 are missing. When the positive terminal 1100 and / or the negative terminal 1200 of the capacitor 1000 are missing, the capacitor 1000 can be judged to be a defective product. When the positive terminal 1100 and the negative terminal 1200 of the capacitor 1000 are both normal, the capacitor 1000 can be judged to be a good product.

[0071] It should be further explained that after obtaining the image of capacitor 1000 through visual inspection mechanism 230, it is intended to determine whether the appearance of capacitor 1000 is complete. When the appearance of capacitor 1000 is complete, capacitor 1000 is preliminarily judged to be a good product. When the appearance of capacitor 1000 is missing, capacitor 1000 is preliminarily judged to be a defective product.

[0072] like Figure 5 As shown, in one embodiment, the good product support device 700 includes a telescopic driving member 710, and a support plate 720 drivingly connected to the telescopic driving member 710, the telescopic driving member 710 can drive the support plate 720 to move along a first direction so that the support plate 720 can support the capacitor 1000 located at the defective product rejection position 40, and the telescopic driving member 710 can also drive the support plate 720 to move along a second direction opposite to the first direction so that the support plate 720 avoids the capacitor 1000 located at the defective product rejection position 40.

[0073] Specifically, under the action of the telescopic driving member 710, the support plate 720 can move in a first direction or a second direction opposite to the first direction, so that the good product support device 700 switches between an extended state and a retracted state. When the support plate 720 moves to support the capacitor 1000 located at the defective product rejection position 40, the good product support device 700 is in an extended state, and when the support plate 720 moves to avoid the capacitor 1000 located at the defective product rejection position 40, the good product support device 700 is in a retracted state.

[0074] More specifically, the telescopic driving member 710 is a cylinder, which is used to drive the support plate 720 to move in the horizontal direction. In this way, when the support plate 720 is driven by the telescopic driving member 710 to move along the second direction, the support plate 720 can avoid the capacitor 1000 located at the defective product rejection position 40, so that the capacitor 1000 falls and is rejected.

[0075] like Figure 5 As shown, the flipping device 300 is used to flip the capacitor 1000 located at the defective product rejection position 40 and transport it to the transition position 50 , and the transition device 400 is used to support the capacitor 1000 located at the transition position 50 .

[0076] Specifically, the flipping device 300 includes a flipping assembly 310, which includes a flipping drive 311 and a second clamp 312 driven and connected to the flipping drive 311. The flipping drive 311 is used to drive the second clamp 312 to flip, so that the second clamp 312 can drive the capacitor 1000 to flip from the defective product rejection position 40 and move to the transition position 50.

[0077] When the good products are transported to the bad product rejection position 40 , the second clamp 312 can clamp the good products, and under the action of the flip driving member 311 , the second clamp 312 drives the good products to flip and move the good products to the transition position 50 .

[0078] It should be noted that flipping the good product means flipping the good product 180°, that is, when the good product is at the defective product rejection position 40, the positive terminal 1100 and the negative terminal 1200 of the good product are facing upward, and when the good product is flipped and moved to the transition position 50, the positive terminal 1100 and the negative terminal 1200 of the good product are facing downward.

[0079] The flip driving member 311 is a motor, and the second clamp 312 can clamp or release the capacitor 1000. After the good product is transported to the bad product rejection position 40, the second clamp 312 can clamp the good product, and under the action of the flip driving member 311, the second clamp 312 drives the good product to flip and move the good product to the transition position 50. When the good product moves to the transition position 50, the second clamp 312 can release the good product, and then rotate in the opposite direction under the action of the flip driving member 311, so as to carry the next good product.

[0080] like Figure 5 As shown, in one embodiment, the flip device 300 further includes a lifting drive assembly 320, which is driven and connected to the flip assembly 310. In this way, the flip assembly 310 can realize the transportation of capacitors 1000 of different specifications. For example, the lifting drive assembly 320 can adjust the height of the flip assembly 310 according to the height of the capacitor 1000. The higher the height of the capacitor 1000, the higher the height of the flip assembly 310 needs to be adjusted accordingly.

[0081] The lifting drive assembly 320 may be a cylinder or an electric screw.

[0082] like Figure 5 , Figure 6 As shown, the transition device 400 is used to support the capacitor 1000 located at the transition position 50, and the transition device 400 includes a support member 410 and a third clamp 420 disposed on the support member 410. The support member 410 is used to support the capacitor 1000 located at the transition position 50, and the third clamp 420 can clamp and limit the capacitor 1000 located at the transition position 50 to prevent the capacitor 1000 from falling.

[0083] It should be noted that the support member 410 is provided with two slots for the positive terminal 1100 and the negative terminal 1200 of the capacitor 1000 to be inserted.

[0084] The third clamp 420 can clamp or release the capacitor 1000 .

[0085] like Figure 2 As shown, in one embodiment, a slide 810 is provided below the defective product rejection position 40, and a defective product collection box 820 is provided below the slide 810. Thus, when defective products move to the defective product rejection position 40, the defective products will first fall into the slide 810, and then enter the collection box under the guidance of the slide 810 for centralized processing.

[0086] like Fig. 9As shown, the transport device 500 is used to transport the capacitor 1000 located at the transition position 50 to the capacitor testing device 600 , so that the capacitor 1000 is tested by the capacitor testing device 600 .

[0087] like Fig. 9 , Fig.10 As shown, specifically, the transport device 500 includes a horizontal driving member 510, a vertical driving member 520 and a fourth clamp 530. The horizontal driving member 510 is used to drive the vertical driving member 520 and the fourth clamp 530 to move in the horizontal direction, and the vertical driving member 520 is used to drive the fourth clamp 530 to move in the vertical direction. When the capacitor 1000 is moved to the transition position 50, the vertical driving member 520 can drive the fourth clamp 530 to descend, clamp the capacitor 1000 with the fourth clamp 530, and then drive the fourth clamp 530 to rise. After that, the horizontal driving member 510 can simultaneously drive the vertical driving member 520 and the fourth clamp 530 to move in the horizontal direction, so that the capacitor 1000 is located above the capacitor testing device 600. Then, the vertical driving member 520 drives the fourth clamp 530 to descend again to insert the capacitor 1000 on the capacitor testing device 600.

[0088] It should be noted that after the posture of the capacitor 1000 is corrected by using the posture correction device 200 and the capacitor 1000 is flipped 180° by the flipping device 300 , the transport device 500 can smoothly insert the capacitor 1000 into the capacitor testing device 600 .

[0089] The transverse driving member 510 and / or the vertical driving member 520 may be a linear motor, an electric lead screw or a cylinder.

[0090] like Fig.11 As shown, in one embodiment, the capacitor testing device 600 includes a capacitor holder 610 and a clamping fixture 620, wherein the capacitor holder 610 is used for inserting the capacitor 1000, and the clamping fixture 620 is used for releasing the capacitor 1000 from the capacitor holder 610 so as to remove the capacitor 1000.

[0091] like Fig.12 , Fig.13 As shown, the capacitor holder 610 includes a housing 611 , a clamping module 612 and a conductive unit.

[0092] An accommodating chamber 61101 is provided inside the shell 611 , and an avoidance opening 61102 communicating with the accommodating chamber 61101 is provided on the top of the shell 611 , and an opening 61103 communicating with the accommodating chamber 61101 is provided on the side of the shell 611 .

[0093] Specifically, the shell 611 includes a base 6111 and an upper cover 6112 arranged on the base 6111 , the base 6111 and the upper cover 6112 cooperate to form a accommodating cavity 61101 , the avoidance port 61102 is opened in the upper cover 6112 , and the opening 61103 is opened in the base 6111 .

[0094] like Figure 12 to Figure 14 As shown, the clamping module 612 is disposed in the accommodating cavity 61101 , and the clamping module 612 includes two conductive clamps 612 a , and the two conductive clamps 612 a are both disposed toward the avoidance opening 61102 .

[0095] Specifically, the clamping module 612 is used to clamp the capacitor 1000, wherein the capacitor 1000 has two electrode terminals (i.e., a positive terminal 1100 and a negative terminal 1200). When the transport device 500 inserts the capacitor 1000 into the capacitor holder 610, the two conductive clamps 612a of the clamping module 612 clamp the two electrode terminals of the capacitor 1000 in a one-to-one correspondence. In addition, since the conductive clamp 612a is conductive, when the conductive clamp 612a is connected to the electrode terminal of the capacitor 1000, the conductive clamp 612a can be conductively connected to the capacitor 1000. By setting the conductive clamps 612a toward the avoidance opening 61102, it is easy to insert the capacitor 1000 into the conductive clamp 612a.

[0096] It is understandable that the conductive clamp 612a can be made of conductive materials such as gold, silver, copper, iron, tin or aluminum.

[0097] The conductive unit includes two conductive members 613 , which are electrically matched with two conductive clamps 612 a in a one-to-one correspondence, and at least a portion of each conductive member 613 is exposed outside the accommodating cavity 61101 .

[0098] Specifically, the two conductive members 613 are in contact with the two conductive clamps 612a respectively, and the conductive members 613 in contact with each other are conductively connected to the conductive clamps 612a. By making the conductive members 613 conductively connected to the conductive clamps 612a and making at least part of each conductive member 613 exposed outside the accommodating cavity 61101, it is convenient to connect the charge and discharge test mechanism, thereby performing charge and discharge tests on the capacitor 1000.

[0099] It should be noted that the charge and discharge test mechanism includes a power supply, which can realize the charge test of the capacitor 1000, and the charge and discharge test mechanism also has a capacitor 1000 discharge device, which can realize the discharge test of the capacitor 1000.

[0100] like Figures 12 to 15As shown, further, the clamping jig 620 can extend into the accommodating cavity 61101 through the opening 61103 to drive the two conductive clamps 612a to perform a loosening action. The conductive clamps 612a can clamp the electrode terminals of the capacitor 1000, and the clamping jig 620 can be used to make the conductive clamps 612a loosen the electrode terminals of the capacitor 1000, thereby facilitating the removal of the capacitor 1000.

[0101] When the capacitor holder 610 is in use, the handling device 500 can insert the two electrode terminals of the capacitor 1000 into the two conductive clamps 612a respectively to fix the capacitor 1000. When the capacitor 1000 is fixed, the electrode terminals of the capacitor 1000, the conductive clamps 612a and the conductive member 613 are electrically matched. When the two conductive members 613 are connected to the charge and discharge test mechanism, the charge and discharge test of the capacitor 1000 can be realized. In the capacitor holder 610, on the one hand, the capacitor 1000 can be fixed. When the capacitor 1000 is fixed, the capacitor holder 610 uses the two conductive clamps 612a to clamp the two electrode terminals of the capacitor 1000 respectively, and no scratches will be left on the body of the capacitor 1000. On the other hand, after the capacitor 1000 is fixed, it is only necessary to electrically connect the conductive member 613 and the charge and discharge test mechanism together to realize the electrical connection between the capacitor 1000 and the charge and discharge test mechanism, which is easy to operate.

[0102] like Fig.13 , Fig.14 As shown, in one embodiment, the conductive clamp 612a includes a limit frame 6121, a reset member 6122 and a clamping unit 6123.

[0103] Specifically, the clamping unit 6123 is used to clamp the electrode terminal of the capacitor 1000. Under the action of the reset member 6122, the clamping unit 6123 maintains a clamped state, and the electrode terminal of the capacitor 1000 can be inserted into the clamping unit 6123, thereby fixing the capacitor 1000.

[0104] More specifically, the clamping unit 6123 includes a first clamping piece 61231 and a second clamping piece 61232. The clamping end of the first clamping piece 61231 cooperates with the clamping end of the second clamping piece 61232 to form a clamping structure. The reset member 6122 is used to drive the clamping end of the first clamping piece 61231 and the clamping end of the second clamping piece 61232 to approach each other. The clamping fixture 620 can drive the clamping end of the first clamping piece 61231 and the clamping end of the second clamping piece 61232 to separate from each other. The clamping end of the first clamping piece 61231 and the clamping end of the second clamping piece 61232 approach each other to clamp the electrode terminal of the capacitor 1000. The clamping end of the first clamping piece 61231 and the clamping end of the second clamping piece 61232 are separated from each other to release the electrode terminal of the capacitor 1000.

[0105] It is understandable that the first clamping piece 61231 and the second clamping piece 61232 can be made of conductive materials such as gold, silver, copper, iron, tin or aluminum.

[0106] Specifically, when fixing the capacitor 1000, the electrode terminal of the capacitor 1000 can be inserted between the clamping end of the first clamping piece 61231 and the clamping end of the second clamping piece 61232. Under the action of the reset member 6122, the electrode terminal of the capacitor 1000 can be clamped by the clamping end of the first clamping piece 61231 and the clamping end of the second clamping piece 61232. When the capacitor 1000 needs to be removed, the clamping fixture 620 can be used to drive the first clamping piece 61231 and the second clamping piece 61232 to separate from each other, thereby loosening the electrode terminal of the capacitor 1000.

[0107] The reset member 6122 is an elastic component, and is disposed between the first clamping piece 61231 and the second clamping piece 61232 .

[0108] Specifically, the reset member 6122 is a spring.

[0109] In one embodiment, the limit frame 6121 includes a left limit plate 61211, a right limit plate 61212 spaced apart from the left limit plate 61211, and an upper limit plate 61213 connecting the left limit plate 61211 and the right limit plate 61212, the upper limit plate 61213 is provided with a limit opening 61214, the first clamping piece 61231 is passed through the limit opening 61214, and the first clamping piece 61231 is abutted against the bottom of the left limit plate 61211, the second clamping piece 61232 is passed through the limit opening 61214, and the second clamping piece 61232 is abutted against the bottom of the right limit plate 61212.

[0110] The left limiting plate 61211 and the right limiting plate 61212 respectively limit the first clamping plate 61231 and the second clamping plate 61232 to prevent the first clamping plate 61231 and the second clamping plate 61232 from being separated under the action of the reset member 6122, and make the clamping end of the first clamping plate 61231 and the clamping end of the second clamping plate 61232 move closer to each other under the action of the reset member 6122.

[0111] In one embodiment, two opposite side walls of the housing 611 are provided with mounting openings 61104 , and two conductive members 613 are respectively inserted through the mounting openings 61104 of the two opposite side walls of the housing 611 .

[0112] Specifically, the conductive member 613 is a copper block, which is installed in the installation opening 61104 , and one end of the copper block is in contact with the conductive clamp 612 a , while the other end of the copper block is exposed from the accommodating cavity 61101 .

[0114] like Figures 13 to 16 As shown, specifically, two openings 61103 are provided on the shell 611, and the two openings 61103 are located on the opposite side walls of the shell 611, the first opening clamp 6221 can extend into the accommodating cavity 61101 from one of the openings 61103, and the second opening clamp 6222 can extend into the accommodating cavity 61101 from the other opening 61103, and when the opening clamp driving source 621 drives the first opening clamp 6221 and the second opening clamp 6222 to move closer to each other, the first opening clamp 6221 and the second opening clamp 6222 can respectively squeeze the first clamping piece 61231 and the second clamping piece 61232, so that the clamping end of the first clamping piece 61231 and the clamping end of the second clamping piece 61232 are separated from each other.

[0115] Further, the clamping assembly 622 includes a first connecting member 6223 connected to the first clamping member 6221, a second connecting member 6224 connected to the second clamping member 6222, and a transmission member connected between the first connecting member 6223 and the second connecting member 6224, and the clamping drive source 621 is drivingly connected to the first clamping member 6221. The clamping drive source 621 is used to drive the first clamping member 6221 to move, thereby driving the second clamping member 6222 to move through the transmission member.

[0116] Specifically, a first rack is provided on the first connecting member 6223, a second rack is provided on the second connecting member 6224, and the transmission member is a gear 6225, which is meshed with the first rack and the second rack respectively.

[0117] More specifically, the clamping drive source 621 is a cylinder. When driving the first clamping member 6221 to move, the clamping drive source 621 can drive the gear 6225 to rotate through the first connecting member 6223, thereby driving the second connecting member 6224 to move through the gear 6225, thereby driving the second clamping member 6222 to move.

[0118] Furthermore, the clamping assembly 622 also includes an installation frame 6226, which is provided with a limiting groove 62261, and the first connecting member 6223 and the second connecting member 6224 are respectively abutted against the upper and lower groove walls of the limiting groove 62261, and the limiting groove 62261 can provide a guiding function for the first connecting member 6223 and the second connecting member 6224.

[0119] like Fig.11 As shown, further, the capacitor testing device 600 also includes a conveyor belt 640 and a conveyor belt driving mechanism 630 for driving the conveyor belt 640 to operate. The capacitor holder 610 is arranged on the conveyor belt 640, and the conveyor belt 640 can drive the capacitor holder 610 to operate.

[0120] Specifically, the conveyor belt driving mechanism 630 is a motor.

[0121] More specifically, the conveyor belt 640 is arranged on a mounting frame, the capacitor holder 610 is arranged on the conveyor belt 640, and the capacitor holder 610 can move under the drive of the conveyor belt 640. The clamping fixture 620 is arranged on the mounting frame, and the clamping fixture 620 is spaced apart from the conveyor belt 640. When the capacitor holder 610 is driven by the conveyor belt 640 so that the two openings 61103 of the capacitor holder 610 can be respectively penetrated by the first clamping piece 6221 and the second clamping piece 6222 of the clamping fixture 620, the clamping driving source 621 can drive the first clamping piece 6221 to move, thereby driving the second clamping piece 6222 to move through the transmission member, thereby realizing the clamping action.
