Description
Technical Field
[0001] This utility model relates to the field of lithium battery processing technology, and in particular to a high-efficiency grinding device for lithium battery processing. Background Technology
[0002] Currently, lithium batteries are secondary batteries that use lithium metal or lithium compounds as electrode materials. With their high energy density, long cycle life, and low self-discharge rate, they have become the core technology of modern energy storage. Their working principle is based on the process of lithium ions intercalating / deintercalating between the positive and negative electrodes (such as the lithium cobalt oxide-graphite system) to realize the mutual conversion of electrical energy and chemical energy. In order to assemble and use the various components of a lithium battery, a corresponding injection-molded battery casing is used to support and house the various components. After injection molding, the outer edge of the battery casing will have a lot of burrs. In order to avoid the burrs affecting the assembly stability, a corresponding grinding mechanism is used to grind and remove the burrs at the edge of the casing.
[0003] However, when using grinding mechanisms to remove burrs from the edges of lithium battery casings, due to the small size of some battery casings, the operator often holds the casing by hand and presses the edge to be ground against the outer wall of the grinding belt to remove the burrs. This method requires the operator to hold the battery casing repeatedly for extended periods, which can easily lead to insufficient stability during the holding process, resulting in insufficient contact between the casing and the outer wall of the grinding belt, thus affecting the grinding quality and efficiency. Therefore, we propose a high-efficiency grinding device for lithium battery processing. Utility Model Content
[0004] The main objective of this invention is to provide a high-efficiency grinding device for lithium battery processing, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A high-efficiency grinding device for lithium battery processing, wherein a drive frame is fixedly installed on the top side of the mounting base, a grinding belt is rotatably arranged inside the drive frame, an electric slide rail is fixedly installed on the bottom side of the mounting base, and a sliding plate is slidably installed on the top side of the mounting base, and the side of the drive shaft of the electric slide rail and the bottom of the sliding plate are fixedly connected.
[0007] A mounting frame is slidably mounted on the top of the sliding plate, and a fixing frame is vertically fixedly mounted on the middle of the side of the mounting frame. A two-way clamping mechanism is provided on the side of the fixing frame.
[0008] A support plate is vertically fixedly installed on the top side of the sliding plate. Hollow tubes are fixedly installed on both sides of the support plate. A pushing mechanism is provided inside each hollow tube, and the pushing mechanism is connected to the outside of the mounting frame.
[0009] As an optional solution to the technical solution of this application, the bidirectional clamping mechanism includes a bidirectional lead screw. The bidirectional lead screw is vertically rotatably mounted inside the fixed frame via bearings. Lifting sleeves are threadedly connected to both sides of the bidirectional lead screw. A transmission rod is horizontally fixedly mounted at the middle of the outer side of each lifting sleeve. The top edge of the transmission rod is slidably mounted inside the mounting frame and the side of the fixed frame. Adhesive plates are slidably mounted at both ends of the inner side of the mounting frame. The top edge of the transmission rod is fixedly connected to the outer side of the adhesive plate. Limiting grooves are vertically formed at the middle of the side of the mounting frame and the side of the fixed frame. The transmission rod is slidably inserted into the limiting groove. A servo motor is fixedly mounted at the top of the outer side of the fixed frame. The bottom of the servo motor drive shaft is fixedly connected to the top of the bidirectional lead screw via a coupling.
[0010] By adopting the above technical solution, the lifting sleeve and its external bonding plate can be moved vertically synchronously by the rotational transmission action of the bidirectional lead screw, and the spacing between the bonding plates can be adjusted to ensure that the bonding plates can be fully attached to the outer wall of the lithium battery for clamping and fixing.
[0011] As an optional solution to the technical solution of this application, the pushing mechanism includes a pushing spring, a transmission plate is slidably installed inside each hollow tube, a connecting rod is horizontally fixedly installed at the middle of the side of each transmission plate, and the top of the side of the connecting rod is fixedly connected to the outer wall of the fixed frame. The pushing spring is movably arranged inside the hollow tube, and the two ends of the pushing spring are respectively movably attached to the outer wall of the transmission plate and the inner wall of the hollow tube. Movable grooves are opened inside both ends of the side of the support plate, and the connecting rod is slidably inserted into the movable groove.
[0012] By adopting the above technical solution, the transmission plate can be provided with a corresponding horizontal pushing force under the action of the pushing spring structure, so that the transmission plate can drive the fixed frame to move horizontally, thereby ensuring that the lithium battery shell clamped and fixed inside the mounting frame can be synchronously attached to the outer wall of the grinding belt, and ensuring that the grinding belt can fully attach to the outer wall of the lithium battery shell for grinding and deburring.
[0013] As an optional solution to the technical solution of this application, a guide slider is fixedly installed at the bottom middle of the fixed frame, and a guide groove is opened laterally at the top middle of the sliding plate, and the guide slider is slidably inserted into the guide groove.
[0014] By adopting the above technical solution, under the guiding sliding action of the guide slide groove on the guide slider, it can be ensured that when the fixed frame is pushed, the fixed frame can only drive the lithium battery shell to move horizontally, thus ensuring that the side edge of the lithium battery shell is fully in contact with the outer wall of the grinding belt.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. The present application discloses a high-efficiency grinding device for lithium battery processing. This device comprises a mounting frame and a fixing frame on the surface of a sliding plate, with a bidirectional lead screw inside the fixing frame. The bidirectional lead screw, driven by the rotation of the lifting sleeves, rotates within the fixing frame, simultaneously causing the lifting sleeves at its outer ends to move vertically in opposite directions. This adjusts the distance between the two sets of bonding plates, allowing them to adhere to the outer walls of lithium battery casings of different sizes. The lithium battery casing is then securely mounted in the center of the mounting frame, ensuring stable contact between the outer edge of the battery casing and the outer wall of the grinding belt. This reduces the operator's labor required to hold the battery casing for extended periods and improves the efficiency of removing burrs from the battery casing edges.
[0017] 2. A high-efficiency grinding device for lithium battery processing according to the technical solution of this application, by providing a support plate on the top side of the sliding plate and hollow tubes on the side rails of the support plate, combined with the pushing spring located inside the hollow tube and its abutting action on the transmission plate, after the burrs on the edge of the battery shell are removed by the grinding belt, the pushing spring can provide a corresponding horizontal pushing force to the mounting frame, so that the mounting frame can drive the lithium battery shell clamped and fixed inside to move horizontally, ensuring that the edge of the lithium battery shell can fully fit against the outer wall of the grinding belt, so that the grinding belt can fully remove and clean the burrs on the outer wall of the battery shell.

[0023] like Figure 1-4 As shown, this utility model provides a technical solution: a high-efficiency grinding device for lithium battery processing. A mounting frame 2 is slidably mounted on the top of a sliding plate 14. A fixing frame 21 is vertically fixed to the middle of the side of the mounting frame 2. A bidirectional lead screw 22 is vertically rotatably mounted inside the fixing frame 21 via bearings. Lifting sleeves 23 are threadedly connected to both sides of the bidirectional lead screw 22. A transmission rod 24 is horizontally fixed to the middle of the outer side of each lifting sleeve 23, and the top of the transmission rod 24 passes through the sliding mounting frame. The mounting frame 2 and the fixed frame 21 are installed inside the side. The two ends of the inner side of the mounting frame 2 are slidably installed with the bonding plate 25, and the top of the side of the transmission rod 24 is fixedly connected to the outer side of the bonding plate 25. The middle of the side of the mounting frame 2 and the side of the fixed frame 21 are vertically opened with the limiting groove 27, and the transmission rod 24 is slidably inserted into the limiting groove 27. The top of the outer side of the fixed frame 21 is fixedly installed with the servo motor 28, and the bottom of the transmission shaft of the servo motor 28 is fixedly connected to the top of the double-acting screw 22 through the coupling.
[0024] In this technical solution (through Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown), a transmission plate 32 is slidably installed inside each hollow tube 31. A connecting rod 34 is horizontally fixedly installed at the middle of the side of each transmission plate 32, and the top of the side of the connecting rod 34 is fixedly connected to the outer wall of the fixed frame 21. A push spring 33 is movably installed inside the hollow tube 31, and the two ends of the push spring 33 are respectively movably attached to the outer wall of the transmission plate 32 and the inner wall of the hollow tube 31. Movable grooves 35 are opened inside both ends of the side of the support plate 3, and the connecting rod 34 is slidably inserted into the movable groove 35.
[0025] In this technical solution (through Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a guide slider 4 is fixedly installed at the bottom center of the fixed frame 21, and a guide groove 41 is horizontally opened at the top center of the sliding plate 14, and the guide slider 4 is slidably inserted into the guide groove 41.
[0026] In this technical solution (through Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a drive frame 11 is fixedly installed on the top side of the mounting base 1. A grinding belt 12 is rotatably installed inside the drive frame 11. A drive motor is installed inside the drive frame 11, and rotating rollers connected to the drive motor are installed on both sides of the grinding belt 12. During the operation of the drive motor, the rotating rollers and the grinding belt 12 can be driven to rotate, thereby grinding and removing the burrs on the edge of the lithium battery shell that is attached to the outside of the grinding belt 12. An electric slide rail 13 is fixedly installed on the bottom side of the mounting base 1, and a sliding plate 14 is slidably installed on the top side of the mounting base 1. The drive shaft side of the electric slide rail 13 is fixedly connected to the bottom of the sliding plate 14.
[0027] During operation, when burrs on the edges of the lithium battery casing need to be polished and removed, the servo motor 28 is turned on by an external control switch, causing it to rotate synchronously within the fixed frame 21 along with the bidirectional lead screw 22. Combined with the guiding and limiting effect of the limiting slide groove 27 on the transmission rod 24, this causes the two sets of lifting sleeves 23 to move synchronously vertically in opposite directions. Then, through the connecting transmission action of the transmission rod 24, the bonding plate 25 moves synchronously vertically, allowing it to adhere to the outer side walls of the two sets of lithium battery casings. The edge of the lithium battery casing to be polished is then attached to the outside of the polishing belt 12. Finally, the electric slide rail 13 is activated, causing it to rotate and drive the sliding plate 14 and the lithium battery casings clamped and fixed inside it. As the battery casing moves horizontally, the drive motor inside the drive frame 11 starts operating synchronously, which drives the grinding belt 12 to rotate, thus grinding and removing burrs from the edges of the horizontally moving lithium battery casing. At the same time, as the burrs are reduced, the reverse push of the push spring 33 allows the transmission plate 32 to move horizontally inside the hollow tube 31. Combined with the connecting rod 34, this provides a horizontal moving force to the fixed frame 21 and the bonding plate 25, allowing the fixed frame 21 to drive the lithium battery casing clamped inside to move horizontally. This ensures that the side edges of the lithium battery casing can fully fit against the outer wall of the grinding belt 12, thereby achieving thorough grinding and removal of burrs from the edges of the lithium battery casing.
