Description

Technical Field

[0001] This utility model relates to the field of peeling device technology, and in particular to a peeling device for the bottom pad of an aluminum electrolytic capacitor. Background Technology

[0002] The base pad of an aluminum electrolytic capacitor is a key component used for insulation, fixation, or buffering at the bottom of the capacitor. Its design, materials, and processing technology directly affect the performance and production efficiency of the capacitor.

[0003] When recycling or repairing large aluminum electrolytic capacitors, the fiberglass base pads (insulating pads) need to be peeled off. In traditional manual operation, workers use cotton swabs dipped in isopropyl alcohol to apply along the edge of the capacitor base pad to dissolve the adhesive. After the adhesive softens, they gently pry up a corner of the capacitor with a knife to gradually separate the base pad. However, workers have to repeatedly apply isopropyl alcohol and repeatedly rotate the large aluminum electrolytic capacitor body to peel it off with a knife, resulting in low peeling efficiency.

[0004] To address the aforementioned problems, this utility model document proposes a peeling device for the bottom pad of an aluminum electrolytic capacitor. Utility Model Content

[0005] This invention provides a peeling device for the bottom pad of an aluminum electrolytic capacitor, which solves the problem of low peeling efficiency caused by the fact that workers have to repeatedly apply isopropyl alcohol and repeatedly rotate the large aluminum electrolytic capacitor body to peel it off with a knife.

[0006] This utility model provides the following technical solution:

[0007] A device for peeling off the base pad of an aluminum electrolytic capacitor, comprising:

[0008] The operating table has a transmission rod rotatably mounted on the top center of the operating table via a bearing. A turntable is fixedly mounted on the top of the transmission rod, and a U-shaped fixing frame is fixedly mounted on the top of the turntable. The bottom of the inner wall of the U-shaped fixing frame is provided with a fixing groove for initially fixing large aluminum electrolytic capacitors.

[0009] The reinforcement component, mounted on the U-shaped mounting bracket, is used to improve the securing effect on large aluminum electrolytic capacitors;

[0010] The spraying assembly, located on the operating table, is used for automatically spraying isopropanol solution.

[0011] In one possible design, a mounting bracket is welded to the bottom of the operating table, and a drive motor and a reducer are fixedly mounted on one side of the mounting bracket. The output shaft of the drive motor is fixedly connected to the input shaft of the reducer, and the output shaft of the reducer passes through the top of the operating table and is fixedly connected to the bottom of the transmission rod.

[0012] In one possible design, the reinforcement component includes two screws symmetrically arranged on a U-shaped fixing frame. The screws are threadedly connected to corresponding threaded holes on the U-shaped fixing frame. One end of the screw penetrates the inner wall of the U-shaped fixing frame and is rotatably mounted with a clamping plate via a bearing. The other end of the screw penetrates the outer wall of the U-shaped fixing frame and is fixedly mounted with a handle.

[0013] In one possible design, the spraying assembly includes a storage tank, a pump, and a vertical rod fixedly mounted on the top of the operating table. The input end of the pump is connected to the inner wall of the storage tank via a pumping pipe, and the output end of the pump is connected to a delivery pipe. The delivery pipe is fixed to the top of the vertical rod, and the other end of the delivery pipe is threadedly connected to a straight nozzle aligned with the peeling seam.

[0014] In one possible design, the top of the operating table is provided with an annular recovery tank for recovering isopropanol solution. The bottom of the inner wall of the annular recovery tank is connected to a recovery pipe. Below the recovery pipe is a recovery bucket. The other end of the recovery pipe is connected to the inner wall of the bucket lid that is snapped onto the top of the recovery bucket.

[0015] In one possible design, support legs are fixedly installed at the four corners of the bottom of the control panel, and casters are fixedly installed at the bottom of the support legs.

[0016] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0017] The working principle and usage process of this technical solution are as follows:

[0018] When using, place the large aluminum electrolytic capacitor into the fixing groove at the bottom of the inner wall of the U-shaped fixing frame to achieve initial fixation. Rotate the two handles respectively. The handles drive the screw to rotate. Since the screw is threadedly connected to the threaded hole on the U-shaped fixing frame, and a clamping plate is installed at one end of the screw through a bearing, the rotation of the screw will cause the clamping plate to move towards the capacitor, thereby clamping the capacitor and further improving the fixing effect of the capacitor, ensuring that the capacitor will not shake during subsequent operations.

[0019] After the drive motor is started, its output shaft is fixedly connected to the input shaft of the reducer. The reducer's output shaft passes through the top of the operating table and is fixedly connected to the bottom of the transmission rod. Through the reducer's deceleration action, the transmission rod is driven to rotate, which in turn drives the turntable and U-shaped fixing frame to rotate, facilitating subsequent spraying and stripping operations. Simultaneously, the liquid pump is started, drawing isopropanol solution from the storage tank through the liquid pumping pipe. The isopropanol solution enters the delivery pipe through the pump's output end and is then sprayed out from the direct nozzle at the other end of the delivery pipe. The direct nozzle is aligned with the power supply. The peeling seam of the capacitor base pad allows isopropyl alcohol solution to be evenly applied to the peeling seam, dissolving and softening the adhesive. During the spraying process, excess isopropyl alcohol solution flows into the annular recovery tank at the top of the workbench. The solution flows into the recovery bucket through the recovery pipe at the bottom of the inner wall of the annular recovery tank, realizing the recovery of isopropyl alcohol solution for later reuse. After the isopropyl alcohol solution softens the adhesive, a corner of the capacitor base pad can be gently pried up with a knife, and the capacitor and isopropyl alcohol spraying can continue to be rotated to ensure that the peeling operation is carried out smoothly. As the turntable rotates, the peeling of the base pad is gradually completed.

[0020] This utility model has the following beneficial effects:

[0021] This invention uses a drive motor to rotate a turntable, causing the capacitor to rotate automatically. At the same time, the spraying component can automatically spray isopropyl alcohol solution, avoiding the tedious process of workers repeatedly applying isopropyl alcohol and rotating the capacitor in traditional manual operations, and greatly improving the peeling efficiency of the aluminum electrolytic capacitor base.

[0022] The reinforcement components in this invention can improve the fixing effect on large aluminum electrolytic capacitors, ensure the stability of the capacitors during the peeling process, and reduce the difficulty of peeling or damage to the capacitors caused by capacitor shaking.

[0023] The design of the annular recovery tank and recovery pipe in this invention can recover isopropanol solution, realize the recycling of solution, reduce costs, and also reduce environmental pollution. Attached Figure Description

[0031] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0032] Example 1

[0033] Please refer to Figure 1-4 A stripping device, comprising:

[0034] The operating table 1 has an anti-static epoxy resin coating on its surface to meet the operation requirements of electronic components. The operating table 1 is the basic support structure of the entire device. A 0Cr alloy steel transmission rod 4 is rotatably mounted on the top center of the operating table 1 through an angular contact ball bearing (model 7206AC). A turntable 5 is fixed on the top of the transmission rod 4. A U-shaped fixing frame 6 is fixed on the top of the turntable 5. The bottom of the inner wall of the U-shaped fixing frame 6 is provided with a fixing groove 7 for initially fixing large aluminum electrolytic capacitors. A silicone buffer pad is pasted in the groove. A reinforcement component is set on the U-shaped fixing frame 6 to improve the fixing effect. A liquid spraying component is set on the operating table 1 for automatically spraying isopropanol solution.

[0035] Support legs 2 are fixedly installed at the four corners of the bottom of the operating platform 1. Casters 3 are fixedly installed at the bottom of the support legs 2 to facilitate the movement of the device. A mounting frame 8 is welded to the bottom of the operating platform 1. A drive motor 9 and a reducer 10 are fixedly installed on one side of the mounting frame 8. The drive motor 9 is a three-phase asynchronous motor (model Y80M2-4) equipped with a worm gear reducer (reduction ratio 1:40) with an output torque ≥20N·m. The output shaft of the motor is connected to the reducer through a flexible coupling (model LM-50) to compensate for axial deviation. The output shaft of the reducer 10 passes through the top of the operating platform 1 and is fixedly connected to the bottom of the transmission rod 4. Through the cooperation of the drive motor 9 and the reducer 10, the transmission rod 4 can be driven to rotate, thereby driving the turntable 5 and the U-shaped fixed frame 6 to rotate, which facilitates multi-angle operation of large aluminum electrolytic capacitors.

[0036] The reinforcement component includes two screws 12 symmetrically arranged on the U-shaped fixing frame 6. The U-shaped fixing frame 6 has corresponding threaded holes 11, and the screws 12 are threaded to the threaded holes 11. One end of the screw 12 passes through the inner wall of the U-shaped fixing frame 6 and is rotatably mounted with a clamping plate 13 through a bearing. The clamping plate 13 is made of bakelite and has anti-slip rubber strips embedded on the contact surface. It is connected to the screw 12 through a deep groove ball bearing (model 6000). The other end of the screw 12 passes through the outer wall of the U-shaped fixing frame 6 and is fixedly mounted with a handle 14. After a large aluminum electrolytic capacitor is placed into the fixing slot 7 for initial fixation, the screw 12 can be rotated by rotating the handle 14, causing the clamping plate 13 to move toward the capacitor, thereby further clamping the capacitor and improving the fixing effect of the capacitor.

[0037] The spraying assembly includes a liquid storage tank 15, a pump 16, and a vertical rod 18, all fixedly mounted on the top of the operating table 1. The liquid storage tank 15 is made of transparent PC plastic. The pump 16 is a diaphragm pump (model DP-25). The input end of the pump 16 is connected to the inner wall of the liquid storage tank 15 via a pumping pipe 17. The output end of the pump 16 is connected to a delivery pipe 19, which is a 304 stainless steel corrugated pipe. The delivery pipe 19 is fixed to the top of the vertical rod 18. The other end of the delivery pipe 19 is threadedly connected to a direct spray head 20 aligned with the peeling seam. The direct spray head 20 uses laser micro-... The nozzle is 0.8mm in diameter and the spray particle diameter is ≤50μm. It can be controlled by an integrated PLC controller (model FX3U-32MR) with three preset working modes (fast spraying / intermittent spraying / fixed-point spraying). The liquid tank 15 stores isopropyl alcohol solution. When isopropyl alcohol needs to be sprayed, the pump 16 is started to extract the isopropyl alcohol solution from the liquid tank 15 through the pump pipe 17 and deliver it to the direct spray head 20 through the delivery pipe 19. The direct spray head 20 is then sprayed onto the peel seam of the capacitor pad, realizing the function of automatically spraying isopropyl alcohol solution.

[0038] This application may also be applied to other fields.

The bottom of the inner wall of the annular recovery tank 21 is connected to a recovery pipe 22. Below the recovery pipe 22 is a recovery bucket 23 with an activated carbon filter layer inside. The other end of the recovery pipe 22 is connected to the inner wall of the bucket lid 24 that is snapped onto the top of the recovery bucket 23. During the spraying of isopropanol solution, excess solution will flow into the annular recovery tank 21 and then into the recovery bucket 23 through the recovery pipe 22, thus realizing the recovery and reuse of isopropanol solution.
