Description

Technical Field

[0001] This utility model relates to the field of capacitor assembly processing technology, and in particular to a testing device for stand-up padding paper for aluminum electrolytic capacitor assemblies. Background Technology

[0002] When assembling and sealing aluminum electrolytic capacitors, paper needs to be placed at the bottom of the aluminum shell. This serves two main purposes. First, it acts as a buffer, reducing the impact between the internal components and the bottom of the aluminum shell when the capacitor is subjected to vibration or shock, thus protecting the internal structure. Second, it provides insulation, preventing the capacitor's electrodes from contacting the bottom of the aluminum shell and causing a short circuit, thereby ensuring the normal operation of the capacitor.

[0003] In large-scale production, automated equipment is generally used for paper padding. However, the following situations may lead to paper padding errors: 1. Paper jams in the paper conveying device, or problems with raw material supply such as paper running out and not being replenished in time. Mechanical failures or inaccurate positioning of the conveying device, or sensor malfunctions that fail to correctly detect whether the aluminum shell has been padded with paper, can all cause paper padding errors and thus affect product quality. Utility Model Content

[0004] The purpose of this invention is to solve the raw material supply problems of existing paper conveying devices, such as paper jams and failure to replenish paper in a timely manner after use. Mechanical failures, inaccurate positioning, or sensor malfunctions in the conveying device, which may prevent the correct detection of whether the aluminum shell has been padded with paper, can all lead to missing padding and thus affect product quality. Therefore, this invention proposes a padding paper inspection device for assembling aluminum electrolytic capacitors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for inspecting padding paper for assembling aluminum electrolytic capacitors includes a base, an aluminum shell, and a conveyor belt. The outer surface of the conveyor belt is provided with multiple clamping assemblies, each consisting of multiple elastic clamping plates. The bottom ends of the elastic clamping plates are fixed to the outer surface of the conveyor belt by bolts. The aluminum shell is clamped between the multiple elastic clamping plates. The conveyor belt has multiple through holes located below the aluminum shell. A support frame is fixedly connected to the top of the base. A light source emitter is fixedly connected to the inner wall of the top of the support frame. An electric telescopic rod is fixedly connected to the inner wall of the top of the support frame. A sliding plate is fixedly connected to the bottom end of the electric telescopic rod. A top rod is fixedly connected to the top of the sliding plate. A photoelectric receiver is embedded at the top of the top rod, which can pass through the through holes.

[0007] Furthermore, a groove is provided on one side of the inner wall of the support frame, and one end of the sliding plate slides in the groove.

[0008] Furthermore, a mounting plate is fixedly connected between the inner walls of each side of the base, and a rotating roller is rotatably inserted between the two mounting plates, with a conveyor belt driving connection between the two rotating rollers.

[0009] Furthermore, a motor is fixedly connected to one side of one of the mounting plates, and the output end of the motor is fixedly connected to one end of one of the rotating rollers.

[0010] Furthermore, a collection box is provided at one end of the conveyor belt.

[0011] Furthermore, a controller is fixedly connected to one side of the outer wall of the support frame, and the controller is electrically connected to the motor, the light source emitter, the photoelectric receiver and the electric telescopic rod.

[0012] Furthermore, the support frame is provided with wire grooves on the top inner wall and one side inner wall.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. When the aluminum shell is transported to the bottom of the light source emitter, the laser beam of the light source emitter shines on the aluminum shell. If the photodetector does not receive a signal, it means that there is padding paper at the bottom of the aluminum shell. If the photodetector receives a signal, it means that there is no padding paper at the bottom of the aluminum shell. This allows for the detection of whether there is padding paper at the bottom of the aluminum shell, thereby avoiding the situation of missing padding paper.

[0015] 2. By retracting the electric telescopic rod, the sliding plate moves upward, causing the top rod to pass through the perforation and push the aluminum shell upward. This causes the aluminum shell to detach from the middle of multiple elastic plates and fall onto the conveyor belt. The conveyor belt transports the aluminum shell without padding paper to the collection box, making it convenient and quick to collect. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-4 A paper-supporting inspection device for assembling aluminum electrolytic capacitors includes a base 1, an aluminum shell 7, and a conveyor belt 4. The outer surface of the conveyor belt 4 is provided with multiple clamping assemblies, each consisting of multiple elastic clamping plates 6. The bottom ends of the elastic clamping plates 6 are fixed to the outer surface of the conveyor belt 4 by bolts. The aluminum shell 7 is clamped between the multiple elastic clamping plates 6. The conveyor belt 4 has multiple through holes 15 located below the aluminum shell 7. A support frame 8 is bolted to the top of the base 1. A light source emitter 9 is bolted to the inner wall of the top of the support frame 8. An electric telescopic rod 11 is bolted to the inner wall of the top of the support frame 8. A sliding plate 13 is bolted to the bottom end of the electric telescopic rod 11. A top rod 14 is bolted to the top of the sliding plate 13. When the electric telescopic rod 11 retracts, it drives the sliding plate 13 to move upward, thereby driving the top rod 14 to move upward. This causes the top rod 14 to pass through the through hole 15 and push the aluminum shell 7 upward, thus pushing the aluminum shell 7 out from between multiple elastic clamping plates 6 and onto the conveyor belt 4. A photoelectric receiver 10 is embedded at the top of the top rod 14. When the aluminum shell 7 is transported to the bottom of the light source emitter 9, the laser beam of the light source emitter 9 shines on the aluminum shell 7. If the photoelectric receiver 10 does not receive a signal, it means that there is padding paper at the bottom of the aluminum shell 7. If the photoelectric receiver 10 receives a signal, it means that there is no padding paper at the bottom of the aluminum shell 7, and the top rod 14 can pass through the through hole 15.

[0023] A groove 12 is provided on one inner wall of the support frame 8. One end of the sliding plate 13 slides in the groove 12, thereby guiding the movement of the sliding plate 13 and enhancing the lifting effect of the aluminum shell 7. Mounting plates 2 are bolted between the inner walls of each side of the base 1. A rotating roller 3 is rotatably connected between the two mounting plates 2. A conveyor belt 4 is driven between the two rotating rollers 3. A motor 5 is bolted to one side of one of the mounting plates 2. The output end of the motor 5 is fixedly connected to one end of one of the rotating rollers 3. Driven by the motor 5, the rotating roller 3 rotates, thereby driving the conveyor belt 4 to rotate, thus lifting the aluminum shell 7. The aluminum shell 7 is conveyed, and a collection box 16 is provided at one end of the conveyor belt 4. Under the conveying action of the conveyor belt 4, the aluminum shell 7 without the padding paper is conveyed into the collection box 16. A controller 18 is fixed to one side of the outer wall of the support frame 8 by bolts. The controller 18 is electrically connected to the motor 5, the light source emitter 9, the photoelectric receiver 10 and the electric telescopic rod 11. The model of the controller 18 is DATA-7311, the model of the light source emitter 9 is E18-LAS / 92, and the model of the photoelectric receiver 10 is EV18-LAS / 32 / 92. The inner wall of the top and one side of the inner wall of the support frame 8 are provided with wire grooves 17.

[0024] The working principle of this embodiment is as follows: First, the photoelectric testing equipment, namely the light source emitter 9 and the photoelectric receiver 10, is debugged and calibrated. The sensor sensitivity and detection threshold are adjusted by placing aluminum shells 7 with and without padding paper (samples with and without padding paper). Then, the aluminum shells 7 with padding paper are clamped between multiple elastic clamps 6. Next, the motor 5 is started, and the rotating roller 3 rotates under the drive of the motor 5, thereby driving the conveyor belt 4 to rotate, thus conveying the aluminum shells 7. When the aluminum shells 7 are conveyed to the area below the light source emitter 9, the laser beam from the light source emitter 9 is directed towards the aluminum shells 7. If the photoelectric receiver 10 does not receive a signal, it indicates that padding paper is placed at the bottom of the aluminum shells 7, and the padding paper affects the light source. If the photoelectric receiver 10 receives a signal after the shielding is applied, it means that there is no padding paper at the bottom of the aluminum shell 7. The light source will pass through the perforation at the bottom of the aluminum shell 7 and be received by the photoelectric receiver 10. The signal will be transmitted to the controller 18 for processing. Then, the controller 18 controls the electric telescopic rod 11 to work. Under the contraction of the electric telescopic rod 11, the sliding plate 13 moves upward, thereby driving the top rod 14 to move upward. This causes the top rod 14 to pass through the perforation 15 and push the aluminum shell 7 upward, thereby pushing the aluminum shell 7 out from between the multiple elastic plates 6 and onto the conveyor belt 4. Under the conveying action of the conveyor belt 4, the aluminum shell 7 without padding paper is transported to the collection box 16, while the aluminum shell 7 with padding paper is transported away for further processing.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
