Description

Technical Field

[0001] This utility model relates to the field of capacitance performance testing technology, specifically to a testing connection device. Background Technology

[0002] After static aging, capacitors typically require performance testing, such as leakage current testing, impedance testing, and withstand voltage testing. Traditionally, this involves manually charging the capacitor using charging and discharging equipment, followed by manually connecting it to testing equipment such as leakage current testing devices, impedance testing devices, and withstand voltage testing devices for performance testing. This manual method suffers from low automation, low production efficiency, and cannot achieve mass production.

[0003] While there are currently test connection devices that can automatically connect capacitors to charging / discharging equipment and testing equipment, these devices typically use a linear conveyor belt to drive racks and capacitors inserted into the racks through the charging / discharging equipment and testing equipment in sequence. During this process, the racks are electrically connected to the two pins of the capacitors, and the racks are in contact with the charging / discharging equipment and testing equipment to conduct electricity, thus connecting the capacitors to the charging / discharging equipment and testing equipment. However, the length of this linear conveyor belt is generally quite long, resulting in a long test connection device and consequently a long production workshop. Utility Model Content

[0025] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0026] Please refer to Figures 1 to 4 An embodiment of this utility model provides a test connection device, including an annular belt 11, a belt drive mechanism 12 for driving the annular belt 11 to rotate, several test fixtures 13, a first discharge track 14, a charging track 15, a test track 16, a second discharge track 17, a loading robot 21, a good product unloading robot 22, a defective product unloading robot, and a defective product box.

[0027] Several test fixtures 13 are spaced apart circumferentially on the outer circumferential surface of the annular belt 11. Rotation of the annular belt 11 causes the test fixtures 13 to move circumferentially along the belt. The number of test fixtures 13 can be adjusted according to actual conditions. A first discharge track 14, a charging track 15, a test track 16, and a second discharge track 17 are sequentially arranged on the outer side of the annular belt 11 along its rotation direction. In this embodiment, the annular belt 11 rotates counterclockwise. A first discharge conductive component is provided on the first discharge track 14, a charging conductive component is provided on the charging track 15, a test conductive component is provided on the test track 16, and a second discharge conductive component is provided on the second discharge track 17. The test fixtures 13 are used to hold and conduct electricity to the two pins 101 of the capacitor 100, i.e., to electrically connect to the two pins 101 of the capacitor 100, and to make contact with the first discharge conductive component, the charging conductive component, the test conductive component, and the second discharge conductive component. The first discharge conductive component, the charging conductive component, and the second discharge conductive component are all used for electrical connection to a charging / discharging device, and the test conductive component is used for electrical connection to a testing device. The number of the first discharge conductive component, the charging conductive component, and the second discharge conductive component can be set according to the actual situation. When the test fixture 13 and its capacitor 100 move to the position corresponding to the charging track 15, the test fixture 13 can contact and conduct electricity with the charging conductive component, thereby charging the capacitor 100 on the test fixture 13 through the charging and discharging equipment. When the test fixture 13 and its capacitor 100 move to the position corresponding to the test track 16, the test fixture 13 can contact and conduct electricity with the test conductive component, thereby performing performance testing on the capacitor 100 on the test fixture 13 through the testing equipment. When the test fixture 13 and its capacitor 100 move to the position corresponding to the first discharge track 14, the test fixture 13 can contact and conduct electricity with the first discharge conductive component, thereby discharging the capacitor 100 on the test fixture 13 through the charging and discharging equipment. When the test fixture 13 and its capacitor 100 move to the position corresponding to the second discharge track 17, the test fixture 13 can contact and conduct electricity with the second discharge conductive component, thereby discharging the capacitor 100 on the test fixture 13 through the charging and discharging equipment. Using a ring belt 11 to move the test fixture 13 can reduce the length of the test connection device, thereby reducing the length of the production workshop. The first discharge track 14, the charging track 15, the test track 16, and the second discharge track 17 are all insulating components.

[0028] In this embodiment, three conductive test components are used, arranged sequentially and at intervals along the rotation direction of the annular belt 11. Three testing devices are also used: a leakage current testing device, an impedance testing device, and a withstand voltage testing device. The first conductive test component is electrically connected to the leakage current testing device, the second to the impedance testing device, and the third to the withstand voltage testing device. The leakage current testing device is used to test the leakage current performance of capacitor 100, the impedance testing device is used to test the impedance performance of capacitor 100, and the withstand voltage testing device is used to test the withstand voltage performance of capacitor 100. Understandably, the number of conductive test components can be set according to actual conditions.

[0029] In this embodiment, the belt drive mechanism 12 includes a belt drive component 121, a drive gear 122, and three driven gears 123. The belt drive component 121 is a motor, which can also be, for example, a motor plus a reducer. An annular belt 11 is sleeved on the drive gear 122 and the three driven gears 123. The drive gear 122 and the three driven gears 123 are respectively located at the four corners on the inner side of the annular belt 11. The drive gear 122 and the driven gears 123 respectively mesh with the teeth 111 on the inner circumferential surface of the annular belt 11. The driving gear 122 is sleeved on the outer circumference of the driving shaft 1221. In practical applications, one end of the driving shaft 1221 is rotatably mounted on the top of the machine tool via a driving bearing seat. The driven gear 123 is sleeved on the outer circumference of the driven shaft 1231. In practical applications, one end of the driven shaft 1231 is rotatably mounted on the top of the machine tool via a driven bearing seat. The belt drive 121 is installed inside the machine tool, and its output end extends from the top of the machine tool. The output end of the belt drive 121 is connected to the driving gear 122 via a transmission gear assembly. The belt drive 121 drives the driving gear 122 to rotate via the transmission gear assembly. Under the meshing action of the teeth on the inner circumferential surface of the driving gear 122, driven gear 123, and annular belt 11, the annular belt 11 and the three driven gears 123 can be driven to rotate. In other embodiments, the number of driven gears 123 can also be other.

[0030] The transmission gear assembly includes a first transmission gear 124 and a second transmission gear 125. The first transmission gear 124 is sleeved on the outer periphery of the output end of the belt drive 121, and the first transmission gear 124 meshes with the second transmission gear 125. The second transmission gear 125 is sleeved on the outer periphery of the drive shaft 1221 and connected to the bottom end of the drive gear 122. The belt drive 121 drives the first transmission gear 124 to rotate, thereby driving the drive shaft and drive gear 122 to rotate via the second transmission gear 125.

[0031] The first discharge conductive component includes a first positive discharge conductive element 141 and a first negative discharge conductive element 142 arranged vertically at intervals, which are used for electrical connection with a charging and discharging device. The charging conductive component includes a positive charging conductive element 151 and a negative charging conductive element 152 arranged vertically at intervals, which are used for electrical connection with a charging and discharging device. The test conductive assembly includes a positive test conductive element and a negative test conductive element arranged vertically at intervals. The positive and negative test conductive elements of the first test conductive assembly are respectively a first positive test conductive element 161 and a first negative test conductive element 162, which are used for electrical connection with leakage current testing equipment. The positive and negative test conductive elements of the second test conductive assembly are respectively a second positive test conductive element 163 and a second negative test conductive element 164, which are used for electrical connection with impedance testing equipment.

The second discharge conductive component includes a second positive discharge conductive element 171 and a second negative discharge conductive element 172 arranged vertically at intervals. The second positive discharge conductive element 171 and the second negative discharge conductive element 172 are used for electrical connection with a charging and discharging device. The test fixture 13 is used to make contact and conduct electricity with the first positive discharge conductive element 141 and the first negative discharge conductive element 142, the positive charging conductive element 151 and the negative charging conductive element 152, the first positive test conductive element 161 and the first negative test conductive element 162, the second positive test conductive element 163 and the second negative test conductive element 164, the third positive test conductive element 165 and the third negative test conductive element 166, the second positive discharge conductive element 171 and the second negative discharge conductive element 172.

[0032] Combination Figure 5 As shown, the loading robot 21 is located on one side of the annular belt 11 and part of the loading robot 21 is located on the inner side of the annular belt 11. The loading robot 21 is used to pull the capacitor 100 out of the tray and insert the two pins 101 of the pulled-out capacitor 100 into the test fixture 13 so that the two pins 101 of the capacitor 100 can be held and turned on by the test fixture 13.

[0033] The loading robot 21 includes a loading seat 211, a first loading drive mechanism 212, a second loading drive mechanism 213, a loading gripper drive mechanism 214, two oppositely arranged loading grippers 215, and a pressing assembly. In practical applications, the loading seat 211 is located at the top of the machine platform. The loading seat 211 is located on one side of the annular belt 11. The first loading drive mechanism 212 is mounted on the loading seat 211 and located above the annular belt 11. Part of the first loading drive mechanism 212 is located inside the annular belt 11. The second loading drive mechanism 213 is mounted on the first loading drive mechanism 212 and located above the annular belt 11. The loading gripper drive mechanism 214 is mounted on the second loading drive mechanism 213 via a connecting plate 2141. Two loading grippers 215 are located at the bottom of the loading gripper drive mechanism 214, with a portion of each gripper protruding from one side. The loading gripper drive mechanism 214 drives the two grippers 215 to move closer or further apart to clamp or release the capacitor 100. A pressing assembly is mounted on the loading gripper drive mechanism 214. The pressing assembly presses down on the capacitor 100 after its two leads 101 are inserted into the test fixture 13 to ensure that the capacitor 100 is fully inserted.

[0034] The pressing assembly includes a pressing drive 216 and a pressing block 217. The pressing drive 216 is located on one side of the feeding gripper drive mechanism 214. The pressing block 217 is located below the pressing drive 216 and above the two feeding grippers 215. The pressing block 217 is connected to the output end of the pressing drive 216. The pressing block 217 is used to press down the capacitor 100. The first feeding drive mechanism 212 is used to drive the second feeding drive mechanism 213 to move towards or away from the center of the annular belt 11, thereby driving the feeding gripper drive mechanism 214, the two feeding grippers 215, the pressing drive 216, and the pressing block 217 to move towards or away from the center of the annular belt 11. The second feeding drive mechanism 213 is used to drive the feeding gripper drive mechanism 214, the two feeding grippers 215, the pressing drive 216, and the pressing block 217 to move up and down. The pressing drive 216 is used to drive the pressing block 217 to move up and down. The second feeding drive mechanism 213 is located above the annular belt 11. Both the first feeding drive mechanism 212 and the second feeding drive mechanism 213 are existing linear screw modules; other types are also acceptable. The pressing drive component 216 is a standard cylinder; other types, such as a hydraulic cylinder, are also acceptable. The feeding gripper drive mechanism 214 is a gripper cylinder.

[0035] During operation, the first feeding drive mechanism 212 first drives two feeding grippers 215 to move away from the center of the annular belt 11, positioning them above one of the capacitors 100 on the tray. Then, the second feeding drive mechanism 213 drives the two feeding grippers 215 downwards, positioning one of the capacitors 100 between them. Next, the feeding gripper drive mechanism 214 drives the two feeding grippers 215 closer together to clamp the capacitor 100. Then, the second feeding drive mechanism 213 drives the two feeding grippers 215 and the capacitor 100 upwards to their initial position, thus removing one of the capacitors 100 from the tray. Then, the first feeding drive mechanism 212 drives the two feeding grippers 215 and the capacitor 100 to move closer to the center of the annular belt 11. Simultaneously, the belt drive mechanism drives the annular belt 11 and several test fixtures 13 to rotate, positioning one of the test fixtures 13 below the capacitor 100 on the feeding robot 21. Then, the second feeding drive mechanism 213 drives the two feeding jaws 215 and the capacitor 100 to move downwards, so as to insert the two pins 101 of the capacitor 100 into the test fixture 13. Then, the pressing drive 216 drives the pressing block 217 to move downwards and the feeding jaw drive mechanism 214 drives the two feeding jaws 215 to move away from each other to release the capacitor 100. Thus, the pressing block 217 can press down on the capacitor 100 so that the two pins 101 of the capacitor 100 are inserted into place. At this time, the part of the capacitor 100 above the two pins 101 (i.e., the capacitor body of the capacitor 100) contacts the top of the test fixture 13. In this way, the two pins 101 of the capacitor 100 are inserted into one of the test fixtures 13, and the two pins 101 of the capacitor 100 can be clamped and turned on by the test fixture 13. Then, the pressing block 217 is driven upward to the initial position by the pressing drive 216. Then, the loading gripper drive mechanism 214, the two loading grippers 215, the pressing drive 216 and the pressing block 217 are driven upward to the initial position by the second loading drive mechanism 213. Then, the two loading grippers 215 are driven to move away from the center of the annular belt 11 by the first loading drive mechanism 212, so that the two loading grippers 215 are above the next capacitor 100 on the tray. Then, the next capacitor 100 is pulled out from the tray in the aforementioned manner and the two pins 101 of the next capacitor 100 are inserted into the next test fixture 13.

[0036] Meanwhile, the belt drive mechanism continues to drive the annular belt 11 to rotate, thereby driving several test fixtures 13 to continue moving. When the test fixture 13 and the capacitor 100 on it move to the position corresponding to the first discharge conductive component of the first discharge track 14 under the drive of the annular belt 11, the test fixture 13 will contact and conduct with the first positive discharge conductive component 141 and the first negative discharge conductive component 142 on the first discharge track 14, respectively. Thus, the two pins 101 of the capacitor 100 can be electrically connected to the charging and discharging equipment through the test fixture 13, the first positive discharge conductive component 141, and the first negative discharge conductive component 142. The charging and discharging equipment can discharge the capacitor 100 through the first positive discharge conductive component 141, the first negative discharge conductive component 142 on the first discharge track 14, and the test fixture 13.

[0037] When the test fixture 13 and the capacitor 100 on it move to the position corresponding to the charging conductive component of the charging track 15, the test fixture 13 will make contact with the positive charging conductive component 151 and the negative charging conductive component 152 on the charging track 15 respectively, so that the two pins 101 of the capacitor 100 can be electrically connected to the charging and discharging device through the test fixture 13, the positive charging conductive component 151, and the negative charging conductive component 152. The charging and discharging device can charge the capacitor 100 through the positive charging conductive component 151, the negative charging conductive component 152 on the charging track 15 and the test fixture 13.

[0038] When the test fixture 13 and the capacitor 100 on it move to the position corresponding to the first test conductive component of the test track 16, the test fixture 13 will make contact with the first positive test conductive component 161 and the first negative test conductive component 162 respectively, so that the two pins 101 of the capacitor 100 can be electrically connected to the leakage current testing device through the test fixture 13, the first positive test conductive component 161, and the first negative test conductive component 162. The leakage current performance of the capacitor 100 can be tested through the leakage current testing device via the first positive test conductive component 161, the first negative test conductive component 162, and the test fixture 13. When the test fixture 13 and the capacitor 100 on it move to the position corresponding to the second test conductive component of the test track 16, the test fixture 13 will make contact with the second positive test conductive component 163 and the second negative test conductive component 164 respectively, so that the two pins 101 of the capacitor 100 can be electrically connected to the impedance testing equipment through the test fixture 13, the second positive test conductive component 163, and the second negative test conductive component 164. The impedance performance of the capacitor 100 can be tested through the impedance testing equipment via the second positive test conductive component 163, the second negative test conductive component 164, and the test fixture 13. When the test fixture 13 and the capacitor 100 on it move to the position corresponding to the third test conductive component of the test track 16, the test fixture 13 will make contact with the third positive test conductive component 165 and the third negative test conductive component 166 respectively, so that the two pins 101 of the capacitor 100 can be electrically connected to the withstand voltage test equipment through the test fixture 13, the third positive test conductive component 165, and the third negative test conductive component 166. The withstand voltage performance of the capacitor 100 can be tested through the withstand voltage test equipment via the third positive test conductive component 165, the third negative test conductive component 166, and the test fixture 13.

[0039] When the test fixture 13 and the capacitor 100 on it move to the position corresponding to the second discharge track 17, the test fixture 13 will make contact with the second positive discharge conductor 171 and the second negative discharge conductor 172 on the second discharge track 17 respectively, so that the two pins 101 of the capacitor 100 can be electrically connected to the charging and discharging device through the test fixture 13, the second positive discharge conductor 171 and the second negative discharge conductor 172 on the second discharge track 17. The capacitor 100 can be discharged by the charging and discharging device through the second positive discharge conductor 171 and the second negative discharge conductor 172 on the second discharge track 17 and the test fixture 13, and the test is completed. In this embodiment, the lengths of the first positive discharge conductive element 141, the first negative discharge conductive element 142, the positive charging conductive element 151, the negative charging conductive element 152, the second positive discharge conductive element 171, and the second negative discharge conductive element 172 can span multiple test fixtures 13, thus enabling continuous discharge and charging of the capacitor 100 on the test fixture 13. Understandably, the lengths of the first positive discharge conductive element 141, the first negative discharge conductive element 142, the positive charging conductive element 151, the negative charging conductive element 152, the second positive discharge conductive element 171, and the second negative discharge conductive element 172 can be set according to actual conditions.

[0040] Since capacitor 100 has undergone charging and discharging in the static aging process, it must be discharged first and then charged. This ensures the accuracy of the performance test of capacitor 100. After the performance test is completed, capacitor 100 is discharged again to prevent it from being charged and to facilitate the unloading of capacitor 100.

[0041] Combination Figure 6 As shown, the good product unloading robot 22 corresponds to one end of the annular belt 11. The first discharge track 14, the charging track 15, the testing track 16, and the second discharge track 17 are sequentially arranged between the loading robot 21 and the good product unloading robot 22 along the rotation direction of the annular belt 11. The good product unloading robot 22 is used to remove the tested and qualified capacitors 100 from the testing fixture 13.

[0042] The good product unloading robot 22 includes a good product unloading base 221, a first good product drive mechanism 222, a second good product drive mechanism 223, a good product gripper drive mechanism 224, and two good product grippers 225 arranged opposite each other. In practical applications, the good product unloading base 221 is located at the top of the machine. An annular belt 11 passes through the good product unloading base 221. The first good product drive mechanism 222 is located on the good product unloading base 221 and above the annular belt 11. The second good product drive mechanism 223 is located on the first good product drive mechanism 222 and above the annular belt 11. The good product gripper drive mechanism 224 is mounted on the second good product drive mechanism 223 via a good product mounting plate 2241. Both good product grippers 225 are located at the bottom of the good product gripper drive mechanism 224 and above the annular belt 11. The good product gripper drive mechanism 224 is used to drive the two good product grippers 225 to move closer or further apart to grip or release the capacitor 100. The first good-quality drive mechanism 222 drives the second good-quality drive mechanism 223 to move closer to or further away from the center of the annular belt 11, thereby driving the good-quality gripper drive mechanism 224 and the two good-quality grippers 225 to move closer to or further away from the center of the annular belt 11. The second good-quality drive mechanism 223 drives the good-quality gripper drive mechanism 224 and the two good-quality grippers 225 to move up and down. The first good-quality drive mechanism 222 and the second good-quality drive mechanism 223 are both existing linear screw modules, but can also be other types. The good-quality gripper drive mechanism 224 is a gripper cylinder. The first good-quality drive mechanism 222, the second good-quality drive mechanism 223, the good-quality gripper drive mechanism 224, and the two good-quality grippers 225 are located above the annular belt 11.

[0043] After the performance test of capacitor 100 is passed, when the test fixture 13 and the capacitor 100 on it move to the position corresponding to the good product unloading robot 22 under the drive of the annular belt 11, the two good product grippers 225 are driven to move by the first good product drive mechanism 222 and the second good product drive mechanism 223 so that the tested and qualified capacitor 100 is located between the two good product grippers 225. Then, the two good product grippers 225 are driven to move closer to each other by the good product gripper drive mechanism 224 to clamp the capacitor 100. Then, the two good product grippers 225 and the capacitor 100 are driven to move upward by the second good product drive mechanism 223. The capacitor 100 is pulled off the test fixture 13. Then, the first good product drive mechanism 222 drives the two good product grippers 225 and the capacitor 100 to move away from the center of the annular belt 11 to a predetermined position. Then, the second good product drive mechanism 223 drives the two good product grippers 225 and the capacitor 100 to move downward to a predetermined position. Then, the good product gripper drive mechanism 224 drives the two good product grippers 225 to move away from each other to release the capacitor 100, thereby realizing the unloading of the capacitor 100. In this way, the good product unloading robot 22 can remove the tested and qualified capacitor 100 from the test fixture 13.

[0044] Combination Figure 7 As shown, the defective product unloading robot is used to remove the unqualified capacitors 100 from the test fixture 13 and place them into the defective product box for storage. In this embodiment, there are two defective product unloading robots, namely the first defective product unloading robot 23a and the second defective product unloading robot 23b. The first defective product unloading robot 23a corresponds to the other end of the annular belt 11, and the second defective product unloading robot 23b corresponds to the side of the annular belt 11 away from the loading robot 21. The first defective product unloading robot 23a is located between the loading robot 21 and the first discharge track 14, and the first discharge track 14 is located between the first defective product unloading robot 23a and the second defective product unloading robot 23b. It can be understood that the number and position of the defective product unloading robots can be set according to the actual situation. The number of defective product boxes corresponds to the number of defective product unloading robots, which is also two, namely the first defective product box 24a and the second defective product box 24b. The first defective product box 24a is located at the other end of the annular belt 11 and corresponds to the first defective product unloading robot 23a. The second defective product box 24b is located on the other side of the annular belt 11 and corresponds to the second defective product unloading robot 23b.

[0045] Both the first defective product unloading robot 23a and the second defective product unloading robot 23b include a defective product unloading seat 231, a first defective product drive mechanism 232, a second defective product drive mechanism 233, a T-shaped gripper connecting seat 234, a defective product gripper drive mechanism 235, and two oppositely arranged defective product grippers 236. In practical applications, the defective product unloading seat 231 is located at the top of the machine platform. The defective product unloading seat 231 of the first defective product unloading robot 23a is located inside the annular belt 11, and the annular belt 11 passes through the defective product unloading seat 231 of the second defective product unloading robot 23b.

[0046] The first defective product drive mechanism 232 is mounted on the defective product unloading seat 231. The first defective product unloading robot 23a, consisting of the first defective product drive mechanism 232, the second defective product drive mechanism 233, the gripper connecting seat 234, the defective product gripper drive mechanism 235, and two defective product grippers 236, is located above the annular belt 11 and the first defective product box 24a. The second defective product unloading robot 23b, consisting of the first defective product drive mechanism 232, the second defective product drive mechanism 233, the gripper connecting seat 234, the defective product gripper drive mechanism 235, and two defective product grippers 236, is located above the annular belt 11 and the second defective product box 24b. The second defective product drive mechanism 233 is mounted on the first defective product drive mechanism 232. The gripper connecting seat 234 is mounted on the second defective product drive mechanism 233. The defective product gripper drive mechanism 235 is located at the bottom end of the gripper connecting seat 234, and both defective product grippers 236 are located at the bottom end of the defective product gripper drive mechanism 235. The defective product gripper drive mechanism 235 is used to drive the two defective product grippers 236 to move closer or further apart to grip or release the capacitor 100. The first defective product drive mechanism 232 is used to drive the corresponding second defective product drive mechanism 233 to move closer to or further away from the center of the annular belt 11, thereby causing the corresponding gripper connecting seat 234, the defective product gripper drive mechanism 235, and the two defective product grippers 236 to move closer to or further away from the center of the annular belt 11. The second defective product drive mechanism 233 is used to drive the gripper connecting seat 234, the defective product gripper drive mechanism 235, and the two defective product grippers 236 to move up and down. The first defective product drive mechanism 232 and the second defective product drive mechanism 233 are both existing linear screw modules; understandably, they could also be other types. The defective product gripper drive mechanism 235 is a gripper cylinder.

[0047] After the performance test of capacitor 100 fails, when the test fixture 13 and the capacitor 100 on it move to the position corresponding to the first defective product unloading robot 23a under the drive of the annular belt 11, the first defective product drive mechanism 232 and the second defective product drive mechanism 233 of the first defective product unloading robot 23a drive the two corresponding defective product grippers 236 to move so that the capacitor 100 is located between the two defective product grippers 236. Then, the defective product gripper drive mechanism 235 of the first defective product unloading robot 23a drives the two defective product grippers 236 to move closer to each other to clamp the capacitor 100. Then, the second defective product drive mechanism 233 of the first defective product unloading robot 23a drives the two defective product grippers 236 and the capacitor 100 to move upward to pull the capacitor 100 off the test fixture 13. The first defective product drive mechanism 232 of the defective product unloading robot 23a drives the two defective product grippers 236 and the capacitor 100 to move away from the center of the annular belt 11, so that the capacitor 100 is above the first defective product box 24a. Then, the second defective product drive mechanism 233 of the first defective product unloading robot 23a drives the two defective product grippers 236 and the capacitor 100 to move downward. Then, the defective product gripper drive mechanism 235 of the first defective product unloading robot 23a drives the two defective product grippers 236 to move away from each other to release the capacitor 100. In this way, the capacitor 100 can fall into the first defective product box 24a. Thus, the first defective product unloading robot 23a removes the unqualified capacitor 100 from the test fixture 13 and puts the removed capacitor 100 into the first defective product box 24a for storage.

[0048] After the performance test of capacitor 100 fails, when the test fixture 13 and the capacitor 100 on it move to the position corresponding to the second defective product unloading robot 23b under the drive of the annular belt 11, the first defective product drive mechanism 232 and the second defective product drive mechanism 233 of the second defective product unloading robot 23b drive the two corresponding defective product grippers 236 to move so that the capacitor 100 is located between the two defective product grippers 236. Then, the defective product gripper drive mechanism 235 of the second defective product unloading robot 23b drives the two defective product grippers 236 to move closer to each other to clamp the capacitor 100. Then, the second defective product drive mechanism 233 of the second defective product unloading robot 23b drives the two defective product grippers 236 and the capacitor 100 to move upward to pull the capacitor 100 off the test fixture 13. The first defective product drive mechanism 232 of the defective product unloading robot 23b drives the two defective product grippers 236 and the capacitor 100 to move away from the center of the annular belt 11, so that the capacitor 100 is above the second defective product box 24b. Then, the second defective product drive mechanism 233 of the second defective product unloading robot 23b drives the two defective product grippers 236 and the capacitor 100 to move downward. Then, the defective product gripper drive mechanism 235 of the second defective product unloading robot 23b drives the two defective product grippers 236 to move away from each other to release the capacitor 100. In this way, the capacitor 100 can fall into the second defective product box 24b. Thus, the second defective product unloading robot 23b removes the unqualified capacitor 100 from the test fixture 13 and puts the removed capacitor 100 into the second defective product box 24b for storage.

[0049] In this embodiment, there are multiple defective product gripper drive mechanisms 235, which are spaced apart along the length of the gripper connecting seat 234. The number of defective product boxes and the number of defective product grippers 236 correspond to the number of defective product gripper drive mechanisms 235. For example, the first defective product unloading robot 23a has four defective product gripper drive mechanisms 235 and eight defective product grippers 236, and four first defective product boxes 24a, which are arranged side by side on the first box support 241. The second defective product unloading robot 23b has two defective product gripper drive mechanisms 235 and four defective product grippers 236, and two second defective product boxes 24b, which are arranged side by side on the second box support 242. It can be understood that the number of defective product gripper drive mechanisms 235, defective product grippers 236, and defective product boxes can be set according to the actual situation.

[0050] In this embodiment, the defective product box is detachable, making it easy to remove the defective product box and capacitor 100 together from the machine.

[0051] This utility model, through the arrangement of an annular belt 11, a belt drive mechanism 12 for driving the rotation of the annular belt 11, several test fixtures 13, a charging track 15, and a test track 16, wherein the charging track 15 is equipped with a charging conductive component and the test track 16 is equipped with a test conductive component, can realize the automatic connection of the capacitor 100 to the charging and discharging equipment and the testing equipment. Compared with the prior art, it has a high degree of automation, improves production efficiency, and can realize mass production. Moreover, the use of an annular belt 11 can reduce the length of the test connection device, thereby reducing the length of the production workshop. Meanwhile, the loading robot 21 can remove the capacitor 100 from the tray and insert the two pins 101 of the removed capacitor 100 into the test fixture 13. The good product unloading robot 22 can remove the qualified capacitor 100 from the test fixture 13. The defective product unloading robot can remove the unqualified capacitor 100 from the test fixture 13 and put the removed capacitor 100 into the defective product box for storage. Thus, the automatic loading, unloading and unloading of the qualified capacitor 100 and the unqualified capacitor 100 can be realized, which further improves the production efficiency.
