Description

Technical Field

[0001] The utility model relates to the technical field of tool holders, in particular to a novel lithium battery pole piece cutting tool holder. Background Art

[0002] The lithium battery pole piece slitting knife holder is a special equipment used in the lithium battery manufacturing process. Its main function is to accurately cut the prepared lithium battery pole pieces to facilitate subsequent battery assembly. The lithium battery pole piece slitting knife holder is an indispensable equipment on the lithium battery production line and is of great significance for ensuring battery quality and production efficiency.

[0003] However, the existing cutting knife has multiple groups of holes on its surface for installing the cutting knife. When connecting it to the knife holder, it is inconvenient to align each hole with the mounting hole on the knife holder. Manual calibration is required when installing bolts in each hole, which is not convenient and the efficiency of installing or replacing the cutting knife is not high. Utility Model Content

[0004] The purpose of the utility model is to provide a novel lithium battery pole piece cutting knife holder to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a novel lithium battery electrode sheet cutting knife holder, comprising a frame, a mounting plate fixedly connected to the surface of the frame, and a control unit for positioning the cutting knife provided on the inner side of the frame, the control unit comprising:

[0006] An adjusting screw is provided, wherein the adjusting screw passes through the frame and is rotatably connected to the frame. A fixed block is fixedly connected to the inner side of the frame. The adjusting screw passes through the fixed block and is rotatably connected. The thread of the adjusting screw is symmetrically arranged with the center line of the fixed block as the axis of symmetry.

[0007] Preferably, a T-shaped block is passed through the inner side of the frame, and the T-shaped block is slidably connected to the inner side of the frame. The adjusting screw passes through the T-shaped block and is threadedly connected. When the adjusting screw is turned, the adjusting screw will be located on the inner side of the frame and rotate. At the same time, because the T-shaped block is located on the inner side of the frame and is slidably connected, and the T-shaped block is passed through and threadedly connected by the adjusting screw, the frame limits the T-shaped block.

[0008] Preferably, a pull rod passes through and is hinged to the surface of one end of the T-shaped block close to the fixed block, and a connecting block passes through and is hinged to the end of the pull rod away from the T-shaped block. After the adjusting screw is turned, the T-shaped block will slide on the inner side of the frame, causing the T-shaped block to gradually move away from the fixed block. When the T-shaped block slides, since the two ends of the pull rod are respectively hinged to the T-shaped block and the connecting block, the sliding of the T-shaped block will drive the pull rod to rotate to a certain extent, and the pull rod will pull the connecting block.

[0009] Preferably, the connecting block passes through the frame and is slidably connected, and the surface of the end of the connecting block away from the pull rod is fixedly connected to a mounting plate. When the connecting block is pulled, it will drive the mounting plate and the anti-slip plate on the inner side of the mounting plate to lock and fix the blade surface of the cutting knife. The side of the mounting plate close to the inner side of the frame is fixedly connected to the anti-slip plate.

[0010] Preferably, a hinged piece is passed through the inner side of the frame. Since the round rod on the surface of the movable sleeve is inserted into the movable groove, and the hinged piece is hinged to the frame, the hinged piece limits the movable sleeve through the round rod, forcing the adjusting screw to move with the movable sleeve when it rotates, and the movable sleeve will pull the hinged piece to rotate through the round rod. The bottom end of the hinged piece is fixedly connected to a side splint.

[0011] Preferably, a movable groove is provided on the inner side of the hinged piece, and the round rod is located in the movable groove, so that the round rod will not get stuck when the hinged piece is pulled to rotate, and when the hinged piece rotates, it will drive the side clamp to clamp the side of the cutting knife, and the adjusting screw passes through and is threadedly connected with a movable sleeve.

[0012] Preferably, a round rod is fixedly connected to the side of the movable sleeve, and the round rod is inserted into a movable groove provided on the inner side of the hinged piece. Mounting holes are provided on the surfaces of the mounting plate and the anti-slip plate.

[0013] Compared with the prior art, the present invention provides a new type of lithium battery pole piece cutting tool holder, which has the following beneficial effects:

[0014] 1. The new lithium battery pole piece slitting knife holder, when the connecting block is pulled, will drive the mounting plate and the anti-skid plate on the inner side of the mounting plate to lock and fix the blade surface of the cutting knife. At the same time, because the round rod on the surface of the movable sleeve is inserted into the movable groove, and the hinged piece is hinged to the frame body, the hinged piece limits the movable sleeve through the round rod, forcing the adjusting screw to move with the movable sleeve when it rotates. At the same time, the movable sleeve will pull the hinged piece to rotate through the round rod. At the same time, the round rod is located in the movable groove, so that the round rod will not get stuck when pulling the hinged piece to rotate, and when the hinged piece rotates, it will drive the side splint to clamp the side of the cutting knife. By fixing the side splint and the anti-skid plate at the same time, the cutting knife can be pre-fixed, so that the staff does not need to support the cutting knife, and can gradually fix the cutting knife through the mounting hole, thereby improving the installation efficiency of the cutting knife.

[0015] 2. This new lithium battery electrode cutting knife holder can prevent the two ends of the cutting knife from offsetting and affecting subsequent installation when the hinged piece rotates and drives the side clamps to clamp the two sides of the cutting knife, thereby improving the accuracy of the cutting knife installation position and reducing the time for manual alignment.

[0021] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a new lithium battery electrode cutting knife frame, including a frame 1, a mounting plate 3 is fixedly connected to the surface of the frame 1, and a control unit 2 for positioning the cutting knife is provided on the inner side of the frame 1. The control unit 2 includes:

[0022] The adjusting screw 21 passes through the frame 1 and is rotatably connected to the frame 1. A fixed block 213 is fixedly connected to the inner side of the frame 1. The adjusting screw 21 passes through the fixed block 213 and is rotatably connected. The threads of the adjusting screw 21 are symmetrically arranged with the center line of the fixed block 213 as the symmetry axis. A T-shaped block 22 passes through the inner side of the frame 1 and is slidably connected to the inner side of the frame 1. The adjusting screw 21 passes through the T-shaped block 22 and is threadedly connected. When the adjusting screw 21 is turned, the adjusting screw 21 will rotate on the inner side of the frame 1. At the same time, because the T-shaped block 22 is located on the inner side of the frame 1 and is slidably connected, and the T-shaped block 22 is passed through and threadedly connected by the adjusting screw 21, the frame 1 limits the position of the T-shaped block 22. A pull rod 23 is inserted through and hingedly connected to the end surface of the T-shaped block 22 near the fixed block 213. A connecting block 24 is inserted through and hingedly connected to the end of the pull rod 23 away from the T-shaped block 22. When the adjusting screw 21 is turned, the T-shaped block 22 slides inside the frame 1, gradually moving the T-shaped block 22 away from the fixed block 213. As the T-shaped block 22 slides, the pull rod 23 is hingedly connected to the T-shaped block 22 and the connecting block 24 at both ends. As the T-shaped block 22 slides, the pull rod 23 rotates to a certain extent, causing the pull rod 23 to pull the connecting block 24. The connecting block 24 penetrates the frame 1 and is slidably connected. A mounting plate 25 is fixedly connected to the end surface of the connecting block 24 away from the pull rod 23. When the connecting block 24 is pulled, it drives the mounting plate 25 and the anti-skid plate 26 inside the mounting plate 25 to lock and secure the cutting edge of the cutting knife. The anti-skid plate 26 is fixedly connected to the side of the mounting plate 25 near the inside of the frame 1. A hinged piece 27 is inserted through the inner side of the frame 1. Because the round rod 211 on the surface of the movable sleeve 210 is inserted into the movable groove 29, and the hinged piece 27 is hinged to the frame 1, the hinged piece 27 limits the movable sleeve 210 through the round rod 211, forcing the adjusting screw 21 to move the movable sleeve 210 when it rotates. At the same time, the movable sleeve 210 pulls the hinged piece 27 to rotate through the round rod 211. The bottom end of the hinged piece 27 is fixedly connected to the side clamp 28. A movable groove 29 is opened on the inner side of the hinged piece 27. The round rod 211 is located in the movable groove 29, so that the round rod 211 will not get stuck when the hinged piece 27 is pulled to rotate. When the hinged piece 27 rotates, it drives the side clamp 28 to clamp the side of the cutting knife. The adjusting screw 21 passes through and is threadedly connected to the movable sleeve 210. A round rod 211 is fixedly connected to the side of the movable sleeve 210 . The round rod 211 is inserted into the movable groove 29 provided on the inner side of the hinge piece 27 . Mounting holes 212 are provided on the surfaces of the mounting plate 25 and the anti-slide plate 26 .

[0023] Based on the above embodiment, when the knife holder fixes the cutting knife for cutting the new lithium battery pole piece, the cutting knife is first selected, and then the frame 1 is turned upside down and placed flat on the workbench, and then the cutting knife is inserted into the inner side of the frame 1, and then the adjusting screw 21 is screwed. The adjusting screw 21 will be located on the inner side of the frame 1 and rotated. At the same time, because the T-shaped block 22 is located on the inner side of the frame 1 and is slidably connected, the T-shaped block 22 is penetrated and threaded by the adjusting screw 21, so that the frame 1 limits the T-shaped block 22. After the adjusting screw 21 is screwed, the T-shaped block 22 will be located on the inner side of the frame 1 and slide, so that the T-shaped block 22 gradually moves away from the fixed block 213. When the T-shaped block 22 slides, since the two ends of the pull rod 23 are respectively hinged to the T-shaped block 22 and the connecting block 24, the sliding of the T-shaped block 22 will drive the pull rod 23 to rotate to a certain extent, and the pull rod 23 pulls the connecting block 24. When the connecting block 24 is pulled When the adjusting screw 21 is rotated, the movable sleeve 210 is limited by the round rod 211, and the movable sleeve 210 is forced to move. At the same time, the movable sleeve 210 is forced to move by the round rod 211, and the movable sleeve 210 is forced to move by the round rod 211. At the same time, the round rod 211 is located in the movable groove 29, so that the round rod 211 will not get stuck when pulling the hinge piece 27 to rotate. When the hinge piece 27 rotates, it drives the side clamping plate 28 to clamp the side of the cutting knife. By fixing the side clamping plate 28 and the anti-skid plate 26 at the same time, the cutting knife can be pre-fixed, so that the staff does not need to support the cutting knife, and can gradually fix the cutting knife through the mounting hole 212, thereby improving the installation efficiency of the cutting knife.

[0024] At the same time, when the hinged piece 27 rotates and drives the side clamping plates 28 to clamp the two sides of the cutting knife, it can also prevent the two ends of the cutting knife from offsetting and affecting subsequent installation, thereby improving the accuracy of the cutting knife installation position and reducing the time of manual alignment.

[0025] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
