Description

Technical Field

[0001] This utility model relates to the field of electrode feeding technology, specifically to an electrode lifting and feeding mechanism. Background Technology

[0002] In the automated production process of lithium batteries, the feeding of electrode sheets (positive electrode sheets and negative electrode sheets) is a key node connecting the electrode sheet cutting and winding / stacking processes. The electrode sheets stacked in the material box need to be stably lifted by the lifting feeding mechanism so that the subsequent robotic arm or gripping component can accurately pick up the materials and ensure the continuity of production.

[0003] Currently, most electrode lifting and feeding mechanisms in the industry use fixed-structure material boxes, meaning the size of the area inside the material box for placing the electrode is fixed and cannot be adjusted according to the electrode width. When production needs change to electrode widths, the entire material box set must be replaced with one that matches the new electrode width. This requires stopping the machine to disassemble, install, and calibrate the material box, resulting in low production efficiency. Utility Model Content

[0004] In view of the above-mentioned technical problems in the existing technology, this utility model provides an electrode lifting and feeding mechanism.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A electrode lifting and feeding mechanism is provided, comprising a support plate, a lifting device, a positioning device, and a material box.

The output end of the drive motor is provided with a drive pulley. The coupling is rotatably mounted on the base, and one end of the coupling is provided with a driven pulley. A belt is wound between the drive pulley and the driven pulley. The lifting assembly is located at the end of the coupling away from the driven pulley. The lifting assembly can move axially under the drive of the coupling to drive the electrode sheets in the material box placement area to move upward.

[0009] Preferably, the lifting assembly includes a lead screw, a threaded sleeve, a lifting rod, and a top plate.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0023] This embodiment provides an electrode lifting and feeding mechanism, such as... Figure 1 As shown, it includes a support plate 1, a lifting device 2, a positioning device 3, and a material box 4. The lifting device 2 is located below the support plate 1, the positioning device 3 is located above the support plate 1, and the material box 4 is located above the positioning device 3. The positioning device 3 can fix the material box 4. The output end of the lifting device 2 can pass through the support plate 1 and the positioning device 3 and extend into the material box 4 to drive the electrode sheet in the material box 4 to move upward. Combination Figures 2 to 4 As shown, the lifting device 2 includes a base 20, a power assembly 21, a coupling 22, and a lifting assembly 23. The power assembly 21 and the coupling 22 are respectively mounted on the base 20. The output end of the power assembly 21 is connected to one end of the coupling 22, and the lifting assembly 23 is connected to the other end of the coupling 22. When the power assembly 21 drives the coupling 22 to rotate, the coupling 22 can transmit power to the lifting assembly 23, so that the lifting assembly 23 can move up and down. The power assembly 21 includes a drive motor 210, which is fixedly mounted on the base 20. The output end of the drive motor 210 is fixedly connected to a drive pulley 211. The coupling 22 is rotatably mounted on the base 20. One end of the coupling 22 is provided with a driven pulley 220. A belt is wound between the drive pulley 211 and the driven pulley 220 so that the power of the drive motor 210 can be transmitted to the coupling 22 through the belt, causing the coupling 22 to rotate. The lifting assembly 23 includes a lead screw 230, a threaded sleeve 231, a lifting rod 232, and a top plate 233. The lead screw 230 is connected to the end of the coupling 22 away from the driven pulley 220. The threaded sleeve 231 is sleeved on the lead screw 230 and threadedly connected to it. The lifting rod 232 is fixedly mounted on the top of the threaded sleeve 231, and the top plate 233 is fixedly connected to the top of the lifting rod 232. In use, when the power assembly 21 drives the coupling 22 to rotate, the coupling 22 can drive the lead screw 230 to rotate. The rotation of the lead screw 230 can cause the threaded sleeve 231 to move axially (i.e., move up and down) along the lead screw 230. The axial movement of the threaded sleeve 231 along the lead screw 230 can cause the top plate 233 to lift the electrode in the material box 4. It should be noted that during the operation of the lifting device 2, after the robotic arm removes the topmost electrode sheet in the material box 4, the lifting device 2 will immediately respond and move upward a preset distance. This distance can be set in advance according to the electrode sheet thickness and the gripping range of the robotic arm, ultimately ensuring that the remaining electrode sheets in the material box 4 are always within the gripping range of the robotic arm. A diffuse reflection photoelectric sensor 234 is installed on the top of the top plate 233. The diffuse reflection photoelectric sensor 234 is embedded in the embedding groove 2330 on the top of the top plate 233, and the top of the top plate 233 is recessed to form the embedding groove 2330. By setting the diffuse reflection photoelectric sensor 234, the presence of electrode sheets above the top plate 233 can be detected in real time. Specifically, when the electrode sheet is lifted and located above the top plate 233, the light emitted by the diffuse reflection photoelectric sensor 234 is reflected by the electrode sheet, and the external receiver can detect the reflected signal, indicating that there is still material in the material box 4. When all the electrode sheets in the material box 4 have been removed, the light emitted by the diffuse reflection photoelectric sensor 234 is unobstructed or the reflected signal disappears. At this time, the diffuse reflection photoelectric sensor 234 outputs an "out of material" signal. When the external receiver receives the "out of material" signal, it can remind the user to replenish the electrode sheets in time through a prompting device (such as a buzzer or indicator light) to avoid the equipment running empty. like Figure 5As shown, the positioning device 3 includes a positioning plate 30 and a driving component. The positioning plate 30 is located on the top of the support plate 1, and the driving component is located on the bottom of the support plate 1. The output end of the driving component passes through the support plate 1 and is fixedly connected to the bottom of the positioning plate 30. A positioning block 300 is fixedly provided on the top of the positioning plate 30. The positioning block 300 can be inserted into the material box 4 under the drive of the driving component to fix the material box 4. The driving component is a lifting cylinder 31, and the lifting plate in the lifting device 2 can pass through the positioning plate 30. There are multiple types of positioning blocks 300. One type of positioning block 300 is conical and distributed around the top of the positioning plate 30. Another type of positioning block 300 is L-shaped and located in the middle of multiple conical positioning blocks 300. The conical positioning blocks 300 can provide guidance when the material box 4 is inserted, while the L-shaped positioning blocks 300 can fit against the side wall of the material box 4 after insertion to restrict the horizontal movement of the material box 4. The positioning device 3 also includes a guide component 32, which is located at the bottom of the positioning plate 30. The guide component 32 includes a guide sleeve 320 and a guide rod 321. The guide sleeve 320 is fixed to the support plate 1, and the guide rod 321 passes through the guide sleeve 320. The top of the guide rod 321 is fixedly connected to the bottom of the positioning plate 30. Combination Figure 6 and Figure 7 As shown, the material box 4 includes a base plate 40 and a vertical plate 41. The base plate 40 has multiple positioning holes 400, which correspond one-to-one with the positioning blocks 300 on the positioning plate 30. A through hole 401 is provided in the middle of the base plate 40, through which the lifting plate in the lifting device 2 can penetrate the base plate 40. Two vertical plates 41 are respectively disposed on both sides of the perforation 401, and a placement area for placing the electrode sheet is formed between the two vertical plates 41. The two vertical plates 41 are slidably disposed on the base plate 40. The two vertical plates 41 can move closer to each other or further away from each other. With this design, when the width of the electrode sheet to be fed changes, the distance between the two vertical plates 41 can be adjusted to accommodate electrode sheets of different widths. On the inner side of each vertical plate 41 (on the opposite side of two vertical plates 41), there are guide blocks 42 arranged at intervals. The guide blocks 42 are arranged vertically, and the inner side of each guide block 42 is formed with a guide groove 420. In use, the four corners of the electrode are respectively located in the guide groove 420. When the electrode is pushed upward by the top plate 233, the guide groove 420 provides guidance for the electrode when it moves upward. A guide plate 43 is provided between the two vertical plates 41. The guide plate 43 is slidably engaged with the outer side of the two vertical plates 41. The outer side of each of the two vertical plates 41 is formed with a groove 410 for engaging the guide plate 43. By providing the guide plate 43, when the two vertical plates 41 move closer or further apart, the guide plate 43 can guide the vertical plates 41 and prevent them from tipping over when sliding.
