Description

Technical Field

[0001] This utility model relates to the field of capacitor production technology, specifically to a transfer device for capacitor production. Background Technology

[0002] In the capacitor manufacturing process, the transfer stage is a crucial link connecting various processes. This is especially true for smaller capacitors, where the efficiency and integrity of transfer directly impact the accuracy of subsequent processing and product yield. Due to their small size and light weight, these capacitors are prone to scattering and disordered stacking during transfer. This not only increases manual handling costs but can also cause electrode damage or casing deformation due to collisions and friction, affecting product performance.

[0003] Currently, existing capacitors are generally picked up by a robotic arm during the transfer process and then transferred to a transmission assembly for further transport. The robotic arm picking process is generally divided into vacuum suction cups and mechanical grippers. However, since capacitors are square or cylindrical in shape, square capacitors are prone to shell deformation due to pressure from the mechanical grippers during the picking process, while cylindrical capacitors are prone to falling off due to differences in surface smoothness when adsorbed by vacuum suction cups. In view of this, a transfer device for capacitor production is proposed. Utility Model Content

[0004] The main objective of this invention is to provide a transfer device for capacitor production that can solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention proposes a transfer device for capacitor production, comprising a robotic arm, wherein the robotic arm is equipped with a gripping mechanism and a stepper motor, and the gripping mechanism includes:

[0006] A fixed chamber, wherein a lower cover plate is bolted to the side of the fixed chamber away from the stepper motor;

[0007] A rotation protection assembly, wherein the rotation protection assembly is disposed inside the fixed compartment;

[0008] A positioning component is disposed on the side of the fixed compartment away from the stepper motor.

[0009] Preferably, the positioning component includes a connecting plate through which a straight rod passes and is slidably connected. A fixing ring is fixedly connected to the outer wall of the straight rod. The fixing ring and the connecting plate are elastically connected by a return spring. A positioning plate is fixedly connected to the end of the straight rod away from the fixing ring, and a protruding rod is fixedly connected to the end of the straight rod near the fixing ring.

[0010] Preferably, a bracket is fixedly connected to the outer wall of the connecting plate, and a swing rod is rotatably connected to the bracket. Both ends of the swing rod are provided with straight slots, and the protruding rod slides in the straight slots.

[0011] Preferably, the connecting plate is penetrated by a crossbar and slidably connected to the crossbar. A second protruding rod is fixedly connected to the crossbar, and the second protruding rod slides in a straight groove. A positioning plate is hinged to the end of the crossbar away from the second protruding rod. During the positioning process of the capacitor, when the capacitor is cuboid, the positioning plate and the positioning plate work together to fix the capacitor. When the capacitor is cylindrical, during the positioning process, the return spring is stretched, the swing rod rotates, and the first and second protruding rods slide in the straight groove, so that the positioning plate and the outer wall of the cylinder abut against each other, thereby fixing the capacitor.

[0012] Preferably, the rotation protection assembly includes a rotating shaft, which is fixed to the output shaft of the stepper motor. A guide bar is fixedly connected to the outer wall of the rotating shaft, and the rotating shaft passes through the disk and is rotatably connected to the disk.

[0013] Preferably, the disc abuts against a friction ring, which is elastically connected to the disc via a compression spring. A hinge rod is hinged to the outer wall of the disc, and a slider is hinged to the end of the hinge rod away from the disc. The slider is fixed to a connecting plate. An electric telescopic rod is fixedly installed on the lower cover plate. A ball bearing is embedded in the telescopic end of the electric telescopic rod, and the ball bearing abuts against the disc. During the rotation of the rotating shaft driven by the output shaft of the stepper motor, the friction ring and the disc rotate under the action of the guide bar. Under the action of the compression spring, the friction between the friction ring and the disc is large, which allows the disc to be rotated, thereby driving the hinge rod to move, causing the slider to drive the connecting plate to move, and thus enabling the positioning plate one and positioning plate two to fix the capacitor.

[0014] Preferably, both the friction ring and the circular ring are penetrated by the guide bar and are slidably connected to the guide bar.

[0015] This utility model provides a transfer device for capacitor production. It has the following advantages:

[0016] (1) The transfer equipment for capacitor production uses a clamping mechanism. The synergistic effect of positioning plate one and positioning plate two is used to clamp and fix the cuboid capacitor together. When it is a cylindrical capacitor, the positioning plate two adapts to fit the outer wall of the cylinder by means of the extension and retraction of the return spring and the rotation of the swing rod. This avoids the problem of shell deformation or vacuum suction cup adsorption and detachment caused by the pressure of traditional mechanical grippers, and ensures that capacitors of different shapes are stable and do not loosen during transfer.

[0017] (2) The transfer equipment for capacitor production uses a rotating protective component. The friction ring and the disc are kept in close contact under the action of the compression spring. During the clamping process of the capacitor, the disc can be driven to rotate, which in turn drives the hinge rod to move, causing the slider to drive the connecting plate to move. This allows the positioning plate one and positioning plate two to fix the capacitor. After the capacitor is fixed, the disc will not be driven to rotate, achieving flexible clamping, ensuring the deformation of the capacitor shell, and improving the yield of subsequent processing.

[0018] (3) The transfer equipment for capacitor production can adjust the position of the ring by using an electric telescopic rod, thereby adjusting the compression of the clamping spring and adjusting the friction between the friction ring and the disc. For capacitors with brittle materials or thin shells, the friction can be reduced to avoid damage caused by excessive clamping; for capacitors with heavy weight or smooth surface, the friction can be increased to ensure sufficient clamping force, prevent slippage during transfer, and improve the equipment's performance for capacitors of different materials and specifications.

[0028] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0029] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-6 This utility model proposes a transfer device for capacitor production, including a robotic arm 1. The robotic arm 1 is equipped with a gripping mechanism 2 and a stepper motor 3. The gripping mechanism 2 includes a fixed chamber 21, a rotation protection component 23 and a positioning component 24. A lower cover plate 22 is bolted to the side of the fixed chamber 21 away from the stepper motor 3. The rotation protection component 23 is located inside the fixed chamber 21, and the positioning component 24 is located on the side of the fixed chamber 21 away from the stepper motor 3.

[0031] In this embodiment of the utility model, in order to clamp a square or cylindrical capacitor, the clamping mechanism 2 specifically includes a positioning component 24 including a connecting plate 241. The connecting plate 241 is penetrated by a straight rod 242 and is slidably connected to the straight rod 242. A fixing ring 244 is fixedly connected to the outer wall of the straight rod 242. The fixing ring 244 and the connecting plate 241 are elastically connected by a return spring. A positioning plate 243 is fixedly connected to the end of the straight rod 242 away from the fixing ring 244. A protruding rod 245 is fixedly connected to the end of the straight rod 242 near the fixing ring 244. A bracket 247 is fixedly connected to the outer wall of the connecting plate 241. A swing rod 246 is rotatably connected to the bracket 247. Both ends of the swing rod 246 are provided with straight slots. The protruding rod 245 slides in the straight slots. The connecting plate 241 is penetrated by a horizontal rod 249 and is slidably connected to the horizontal rod 249. A second protruding rod 248 is fixedly connected and slides in a straight slot. A second positioning plate 2410 is hinged to the end of a crossbar 249 away from the second protruding rod 248. When the capacitor is cuboid, the two sets of positioning plates 243 and 2410 work together to fix the capacitor. When the capacitor is cylindrical, after the positioning plate 243 abuts against the capacitor, the return spring is stretched during the movement of the positioning plate 243 toward the capacitor, the swing rod 246 rotates, and the first protruding rod 245 and the second protruding rod 248 slide in the straight slot, so that the second positioning plate 2410 abuts against the outer wall of the capacitor, thereby fixing the capacitor. This avoids the problem of shell deformation or vacuum suction cup adsorption and detachment caused by the pressure of traditional mechanical grippers, and ensures that capacitors of different shapes are stable and do not loosen during transportation.

[0032] Furthermore, to prevent deformation of the capacitor casing during clamping, the rotation protection assembly 23 specifically includes a rotating shaft 231, which is fixed to the output shaft of the stepper motor 3. A guide bar 232 is fixedly connected to the outer wall of the rotating shaft 231. The rotating shaft 231 passes through the disc 233 and is rotatably connected to the disc 233. The disc 233 abuts against a friction ring 234, which is elastically connected to the ring 235 via a compression spring. A hinge rod 236 is hinged to the outer wall of the disc 233. A slider is hinged to the end of the disc 233 away from the disc 233, and the slider is fixed to the connecting plate 241. An electric telescopic rod 237 is fixedly installed on the lower cover plate 22. A ball bearing is embedded in the telescopic end of the electric telescopic rod 237, and the ball bearing abuts against the disc 233. Both the friction ring 234 and the circular ring 235 are penetrated by the guide bar 232 and are slidably connected to the guide bar 232. During the process of the stepper motor 3 driving the rotating shaft 231 to rotate, the friction ring 234 and the circular ring 235 rotate under the action of the guide bar 232, and... Under the action of the compression spring, the friction between the friction ring 234 and the disc 233 is relatively large, which allows the disc 233 to be driven to rotate, thereby driving the hinge rod 236 to move, causing the slider to drive the connecting plate 241 to move, and thus allowing the positioning plate 1 243 and positioning plate 2410 to fix the capacitor. After the capacitor is fixed, the disc 233 overcomes the friction force, and the rotating shaft 231 rotates relative to the disc 233. The disc 233 will not be driven to rotate, achieving flexible clamping, ensuring the deformation of the capacitor shell, and improving the yield of subsequent processing. Furthermore, by using the electric telescopic rod 237, the position of the ring 235 can be adjusted, thereby adjusting the compression of the compression spring, and adjusting the friction force between the friction ring 234 and the disc 233. For capacitors with brittle materials or thin shells, the friction force can be reduced to avoid damage caused by over-clamping; for capacitors with heavy weight or smooth surfaces, the friction force can be increased to ensure sufficient clamping force, prevent slippage during transportation, and improve the equipment's performance for capacitors of different materials and specifications.

[0033] The friction force between the friction ring 234 and the disk 233 is calculated based on the pressure value of the compression spring multiplied by its elastic coefficient and the friction coefficient between the friction ring 234 and the disk 233.

[0034] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all general standard parts or components known to those skilled in the art. Their structure and principle can be known by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here.

[0035] In use, the stepper motor 3 drives the rotating shaft 231 to rotate. Under the action of the guide bar 232, the friction ring 234 and the circular ring 235 rotate. Under the action of the compression spring, the friction between the friction ring 234 and the disc 233 is large, which allows the disc 233 to be driven to rotate, thereby driving the hinge rod 236 to move. This causes the slider to drive the connecting plate 241 to move, causing the positioning plate 1 243 and the positioning plate 2410 to move towards the capacitor. When the capacitor is a cuboid, the two sets of positioning plates 1 243 and 2410 move towards the capacitor. During the fixing process, positioning plate 1 243 and positioning plate 2410 work together to fix the capacitor. When the capacitor is cylindrical, after positioning plate 1 243 comes into contact with the capacitor, during the movement of positioning plate 1 243 toward the capacitor, the return spring is stretched, the swing rod 246 rotates, and protrusion rod 1 245 and protrusion rod 248 slide in the straight groove, so that positioning plate 2410 comes into contact with the outer wall of the capacitor, thereby fixing the capacitor. After the capacitor is fixed, it is placed on the conveyor belt and finally sorted.

[0036] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
