Description

Technical Field

[0001] This utility model relates to the field of capacitor processing technology, and in particular to a fully automatic capacitor capping machine. Background Technology

[0002] Capacitor processing refers to a series of manufacturing processes from raw materials to the final finished capacitor, covering core component preparation, assembly, performance control and quality inspection. The fully automatic capacitor cap-fitting machine is an automated equipment specifically used in the capacitor production process to automatically assemble the caps onto the capacitor shell. It is mainly used in the large-scale production of electrolytic capacitors, film capacitors, etc. By replacing manual operation, it achieves efficient and accurate assembly, greatly improving production efficiency and product consistency.

[0003] In the existing technology, during the capacitor processing, it is necessary to cover and assemble the cap onto the capacitor shell. In order to ensure the assembly quality of the cap, the cap feeding machine needs to use a cylinder to assist in the extrusion assembly. During processing, the cap needs to be installed on the end of the piston rod of the cylinder for subsequent processing, which is quite laborious. It is not possible to automatically feed the cap when the piston rod of the cylinder retracts, which affects the processing efficiency. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that existing glue cap feeding machines require the use of cylinders for assisted extrusion assembly to ensure the assembly quality of glue caps. However, during processing, the glue caps need to be installed onto the piston rod end of the cylinder for subsequent processing, which is laborious and cannot automatically feed the glue caps when the cylinder piston rod retracts, thus affecting processing efficiency. Therefore, a fully automatic capacitor glue cap feeding machine is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A fully automatic capacitor cap applicator includes a frame, a conveyor, and capacitors. The conveyor is located inside the frame, and the capacitors are placed on the conveyor belt. A placement slot is formed on the inner wall of the frame, and multiple caps are placed inside the placement slot. A first cylinder is fixedly connected to the side wall of the frame, and a pusher plate is fixedly connected to the piston rod end of the first cylinder, extending into the placement slot. A discharge port is formed on the bottom inner wall of the placement slot. A second cylinder is fixedly connected to the top inner wall of the frame, and a push rod is fixedly connected to the piston rod end of the second cylinder. A sleeve is fitted onto the rod wall of the push rod, and a storage rack is fixedly connected to the bottom of the sleeve. The bottom end of the push rod extends to the top inner wall of the storage rack and is fixedly connected to a pressure plate.

[0006] Preferably, the frame is threadedly connected to the inner wall of the top of the placement slot with a threaded end cap.

[0007] Preferably, the inner wall of the storage rack is fixedly connected with a rubber anti-slip pad.

[0008] Preferably, a fixed base is fixedly connected to the inner wall of the top of the frame, a pressure sensor is fixedly connected to the inner wall of the fixed base, and a controller is provided inside the frame, the controller being electrically connected to the pressure sensor.

[0009] Preferably, a fixing plate is fixedly connected to the inner wall of the sleeve, and a metal elastic strip is fixedly connected to the top of the fixing plate. The end of the metal elastic strip opposite to the fixing plate is fixedly connected to the end of the piston rod of the second cylinder.

[0010] Preferably, the inner wall of the sleeve is provided with a strip groove, and a guide block is fixedly connected to the end of the piston rod of the second cylinder, the guide block being slidably disposed on the inner wall of the strip groove.

[0011] Compared with the prior art, this utility model provides a fully automatic capacitor glue-filling cap machine, which has the following beneficial effects: 1. This fully automatic capacitor capping machine uses the extension of the piston rod of the second cylinder to drive the push rod, sleeve and storage rack to descend synchronously. The storage rack is first aligned with the top of the capacitor, and the cap inside is aligned with the position to be capped on the capacitor. The pressure plate at the bottom of the push rod then presses down to press the cap in the storage rack into the top of the capacitor, completing the capping action.

[0012] 2. This fully automatic capacitor cap feeding machine connects to a pusher plate via the piston rod of the first cylinder on the side wall of the frame. The pusher plate extends into the placement groove. When the storage rack below is empty, the first cylinder is activated, and the pusher plate pushes the cap at the bottom of the placement groove along the groove wall to the discharge port at the bottom of the placement groove. The cap falls from the discharge port into the storage rack, completing the precise feeding of a single cap.

[0013] 3. This fully automatic capacitor cap applicator uses a fixed plate on the inner wall of the sleeve and a metal elastic strip to form a buffer structure. One end of the metal elastic strip is connected to the fixed plate, and the other end is fixed to the end of the piston rod of the second cylinder. During pressing, it can absorb excess impact force through elastic deformation to avoid excessive pressure that could damage the capacitor or cap. The strip groove on the inner wall of the sleeve slides in conjunction with the guide block at the end of the piston rod of the second cylinder to ensure that the push rod and the storage rack move vertically during lifting and lowering, thus preventing tilting that could cause the cap to be installed off-center.

Detailed Implementation

[0016] 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.

[0017] Reference Figure 1-3 The fully automatic capacitor cap applicator includes a frame 1, a conveyor 2, and capacitors 3. The conveyor 2 is located inside the frame 1, and the capacitors 3 are placed on the conveyor belt. The inner wall of the frame 1 has a placement groove, and multiple caps 4 are placed inside the placement groove. A first cylinder 6 is fixedly connected to the side wall of the frame 1. A pusher plate 7 is fixedly connected to the piston rod end of the first cylinder 6 and extends into the placement groove. A discharge port is located on the bottom inner wall of the frame 1 in the placement groove. A second cylinder 8 is fixedly connected to the top inner wall of the frame 1. A push rod 9 is fixedly connected to the piston rod end of the second cylinder 8. A sleeve 10 is fitted on the rod wall of the push rod 9. A storage rack 12 is fixedly connected to the bottom of the sleeve 10. The bottom rod wall of the push rod 9 extends to the top inner wall of the storage rack 12 and is fixedly connected to a pressure plate 11.

[0018] The inner wall of the top of the frame 1 is threaded with a threaded end cap 5. The inner wall of the storage rack 12 is fixedly connected with a rubber anti-slip pad 13. The inner wall of the top of the frame 1 is fixedly connected with a fixed seat 14. The inner wall of the fixed seat 14 is fixedly connected with a pressure sensor 15. The inside of the frame 1 is equipped with a controller 16, which is electrically connected to the pressure sensor 15.

[0019] The frame 1 serves as the equipment foundation and integrates capacitor conveying, cap supply and pressing mechanisms. The conveyor 2 is responsible for continuously conveying capacitors 3 to the processing position. The placement slot in the frame 1 stores caps 4. Through the linkage of the first cylinder 6 and the second cylinder 8, the automatic supply of caps and capacitor cap insertion are completed. The entire process requires no manual intervention and achieves fully automated production.

[0020] The placement slot of the frame 1 is used to stack and store multiple plastic caps 4. The threaded end cap 5 at the top can be unscrewed for easy periodic replenishment of plastic caps 4. The structure of the placement slot ensures that the plastic caps 4 are arranged in an orderly manner, providing a stable supply for subsequent pushing. The piston rod of the first cylinder 6 on the side wall of the frame 1 is connected to the pusher plate 7. The pusher plate 7 extends into the placement slot. When the storage rack 12 below is empty, the first cylinder 6 is activated, and the pusher plate 7 pushes the plastic cap at the bottom of the placement slot along the slot wall to the discharge port at the bottom of the placement slot. The plastic cap falls from the discharge port into the storage rack 12, completing the precise feeding of a single plastic cap.

[0021] The conveyor 2 carries the capacitor 3 and transports it to the processing position directly below the second cylinder 8 according to a preset rhythm. The second cylinder 8 at the top of the frame 1 is the power source for pressing the cap. Its piston rod is fixedly connected to the push rod 9. The sleeve 10 sleeved on the push rod 9 is fixed to the storage rack 12. The storage rack 12 temporarily stores the rubber cap 4 falling from the discharge port. The rubber anti-slip pad 13 on the inner wall increases the friction and prevents the rubber cap 4 from sliding or shifting during movement. When the capacitor 3 reaches the processing position, the piston rod of the second cylinder 8 extends, driving the push rod 9, sleeve 10 and storage rack 12 to descend synchronously. The storage rack 12 first aligns with the top of the capacitor 3, and the rubber cap 5 inside it aligns with the position to be capped on the capacitor. The pressure plate 11 at the bottom of the push rod 9 then presses down, pressing the rubber cap in the storage rack 12 into the top of the capacitor 3, completing the capping action. Subsequently, the piston rod of the second cylinder 8 retracts, which can pull the sleeve 10 and storage rack 12 to lift, facilitating the continuous assembly of the rubber cap 4.

[0022] To avoid damage to capacitor 3 or rubber cap 4 due to excessive pressure, such as Figure 1-3 As shown, a fixing plate 18 is fixedly connected to the inner wall of the sleeve 10, and a metal elastic strip 17 is fixedly connected to the top of the fixing plate 18. The end of the metal elastic strip 17 facing away from the fixing plate 18 is fixedly connected to the end of the piston rod of the second cylinder 8.

[0023] The inner wall of the sleeve 10 is provided with a strip groove, and the piston rod end of the second cylinder 8 is fixedly connected to a guide block 19, which is slidably disposed on the inner wall of the strip groove.

[0024] The fixing plate 18 on the inner wall of the sleeve 10 and the metal elastic strip 17 form a buffer structure. One end of the metal elastic strip 17 is connected to the fixing plate 18, and the other end is fixed to the end of the piston rod of the second cylinder 8. During pressing, it can absorb excess impact force through elastic deformation to avoid excessive pressure that could damage the capacitor 3 or the rubber cover 4. The strip groove on the inner wall of the sleeve 10 slides in cooperation with the guide block 19 at the end of the piston rod of the second cylinder 8 to ensure that the push rod 9 and the storage rack 12 move vertically during lifting and lowering, thus avoiding tilting that could cause the rubber cover to be installed off-center.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. 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.
