Description

Technical Field

[0001] This utility model relates to the field of capacitance detection technology, and in particular to a high-current surge device for an aging sorting machine. Background Technology

[0002] Aluminum foil generates numerous burrs during the cutting process, and these transverse burrs can become longitudinal burrs during the stapled feeding process. Excessive longitudinal burrs can puncture the electrolytic paper, causing a short circuit between the positive and negative foils and resulting in defects. Although the stapled machine's output and the aging machine's input have short-circuit detection devices, they are ineffective for products on the verge of puncture. Therefore, an aging sorting machine is used to remove products with excessive burrs and those on the verge of puncturing the electrolytic paper using a high-current surge. Under normal circumstances, the clamping head is flat. If the product does not have a bottom bulge, the clamping head and the product's aluminum shell are insulated due to the presence of a rubber tube, and the machine classifies it as a good product. If the product has a bottom bulge, the clamping head and the product's aluminum shell make good contact, generating a signal, and the machine classifies it as a defective product with a bottom bulge.

[0003] During surge testing, existing aging sorting machines sometimes experience short-circuit explosions in defective products with excessive aluminum foil burrs under high-current impact. The electric arc generated by the short circuit melts the internal metal of the product, and the high temperature causes the electrolyte to vaporize, generating high pressure. Under high temperature and pressure, the molten material breaks through the explosion-proof grooves on the bottom of the product and is ejected at high speed onto the top pressure head of the sorting machine's clamp. Since the clamp pressure head is used as an electrode for bottom drum testing, if the metal deposits on the clamp pressure head are not cleaned in time, the aluminum shell will make good contact with the clamp pressure head, and even good products will be misjudged as defective. Every time the machine rotates, this clamp will generate one false bottom drum defect, and the misjudged product must be put back on the machine for another test, resulting in machine occupancy and wasted manpower. At the same time, the metal deposits on the clamp pressure head can only be removed with a file, and repeated filing will make the pressure head uneven, requiring periodic replacement of all clamps, increasing maintenance costs. Utility Model Content

This device is installed on the test bench of the aging sorting machine. When a product is transferred to this device, the grippers at the inlet / outlet station first remove the capacitor from the aging machine fixture. Then, a rotating assembly drives the grippers and capacitor to rotate 120 degrees. A high-current surge test is then performed using a surge tester. After the test, the product is discharged through a discharge circuit and then placed back onto the aging sorting machine fixture. This eliminates the need for the high-current surge test to be performed on the aging sorting machine fixture, thus solving the problem of misjudgment of the product's bottom due to damage to the sorting machine fixture.

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0019] As described in the background section, when existing aging sorting machines are performing surge tests, defective products may short-circuit and explode under the impact of high current. The molten material, under high temperature and pressure, breaks through the explosion-proof grooves on the bottom of the product and is ejected at high speed onto the top pressure head of the sorting machine's clamps. This causes a false defective product to be generated on the clamp every time the machine rotates. The falsely judged product must be put back on the machine for another test, resulting in machine occupation and waste of human resources. At the same time, the metal deposits on the top pressure head of the clamps can only be removed with a file. After many filings, the top pressure head will also become uneven, requiring all clamps to be replaced periodically, which increases maintenance costs.

[0020] To solve this technical problem, this utility model provides a high-current surge device for an aging sorting machine. Installed on the test bench of the aging sorting machine, when a product is transferred to this device, the gripper 7 at the inlet / outlet station 4 first removes the capacitor from the aging machine fixture. Then, the rotating assembly 3 drives the gripper 7 and the capacitor to rotate 120 degrees, and a high-current surge test is performed by the surge tester 1. After the test, the product is discharged through the discharge circuit 2 and then placed back onto the aging sorting machine fixture. This eliminates the need for the high-current surge test to be performed on the aging sorting machine fixture, solving the problem of misjudgment of the product's bottom due to damage to the sorting machine fixture.

[0021] For details, please refer to Figure 1-8 The high-current surge device for aging sorting machines specifically includes: Surge tester 1 and discharge circuit 2, the surge tester 1 is used to test the capacitor, and the discharge circuit 2 is used to discharge the capacitor under test; Rotating component 3, which is provided with feeding / discharging station 4, surge test station 5 and discharge station 6, and each feeding / discharging station 4, surge test station 5 and discharge station 6 is equipped with grippers 7.

When the gripper 7 is at the feeding / discharging station 4, it picks up and puts in the capacitor. When the gripper 7 is at the surge test station 5, it is electrically connected to the surge tester 1 through the carbon brush assembly 8. When the gripper 7 is at the discharge station 6, it is electrically connected to the discharge circuit 2 through the carbon brush assembly 8.

At this time, the gripper 7 is connected to the surge tester 1 through the carbon brush assembly 8, triggering the surge tester 1 to test the capacitor on the gripper 7. Then it rotates 120 degrees again, and at this time the gripper 7 is connected to the discharge circuit 2 through the carbon brush assembly 8 to discharge the capacitor on the gripper 7. Then it rotates 120 degrees again to put the capacitor on the gripper 7 back onto the aging sorting machine fixture.

At this time, the gripper 7 is connected to the surge tester 1 through the carbon brush assembly 8, triggering the surge tester 1 to test the capacitor on the gripper 7. Then it rotates 120 degrees again, and at this time the gripper 7 is connected to the discharge circuit 2 through the carbon brush assembly 8 to discharge the capacitor on the gripper 7. Then it rotates 120 degrees again to put the capacitor on the gripper 7 back onto the aging sorting machine fixture. Then the aging sorting machine fixture closes, the gripper 7 opens, and the rotation component 3 ends the cycle. The aging sorting machine fixture changes station to enter the next cycle.

[0028] Example 2 The high-current surge device for the aging sorting machine provided in Example 1 has been further optimized, specifically, as follows: Figure 2 As shown, the rotating assembly 3 includes a mounting plate 301, a servo motor 302, and a turntable 303.

At this time, the gripper 7 is connected to the surge tester 1 through the carbon brush assembly 8, triggering the surge tester 1 to test the capacitor on the gripper 7. Then it rotates 120 degrees again, and at this time the gripper 7 is connected to the discharge circuit 2 through the carbon brush assembly 8 to discharge the capacitor on the gripper 7. Then it rotates 120 degrees again to put the capacitor on the gripper 7 back onto the aging sorting machine fixture. Then the aging sorting machine fixture closes, and the gripper 7 opens.
