Description

Technical Field

[0001] This utility model relates to the field of lithium battery processing technology, specifically a positioning device for processing lithium battery cells. Background Technology

[0002] Lithium metal is chemically extremely reactive, a characteristic that necessitates stringent environmental requirements during processing, storage, and use. With continuous technological advancements, lithium batteries have become the mainstream product. The battery cell, constructed by stacking lithium battery cells layer by layer, often requires specific fixtures to secure the size-matched cells during the conventional processing and positioning stages, ensuring the precision and stability of the manufacturing process.

[0003] Currently, most existing positioning devices for lithium battery cell processing lack flexible angle adjustment capabilities, making it difficult to quickly change the angle of the positioning structure to adapt to the processing needs of battery cells with different shapes and layouts. Moreover, the positioning components are often fixed structures, requiring a significant amount of time to reinstall and debug the positioning device when switching to processing different types of battery cells, which cannot achieve efficient and rapid conversion and results in low overall processing efficiency. In view of this, we propose a positioning device for lithium battery cell processing. Utility Model Content

[0004] The main objective of this invention is to provide a positioning device for processing lithium battery cells, which can solve the problems mentioned in the background art.

[0005] A positioning device for processing lithium battery cells includes a base plate, a slide rail fixedly connected to the top of the base plate, an electric cylinder base fixedly connected to the top of the base plate, a push block fixedly connected to the output end of the electric cylinder base, and a positioning structure fixedly connected to the top of the push block. The positioning structure includes:

[0006] A placement plate is fixedly connected to the top of the push block, and a fixed shaft is fixedly connected to the top of the placement plate;

[0007] A plug-in block is slidably connected to the top of the fixed shaft, and a synchronization plate is fixedly connected to the top of the plug-in block;

[0008] A pull rod is fixedly connected to the top of the synchronization plate, and a plug rod is fixedly connected to the bottom of the synchronization plate;

[0009] A placement seat is fitted onto the outer wall of the fixed shaft, and a placement bracket is fixedly connected to the outer wall of the placement seat.

[0010] Preferably, the top of the fixed shaft is provided with a square groove, the outer wall of the insertion block is slidably connected to the inner wall of the square groove, and the fixed shaft and the insertion block are elastically connected by a compression spring.

[0011] Preferably, the plug rod is provided in two sets, and the bottom of both sets of plug rods is inserted into the top of the placement base. The top of the placement base is provided with four sets of plug holes, which are distributed in a circle, and the plug rods can be inserted into the plug holes.

[0012] Preferably, the placement bracket is provided in four sets, and modular pressure blocks are detachably connected to the placement bracket. The modular pressure blocks have a U-shaped design, and the inner wall of the modular pressure block is snapped onto the outer wall of the placement bracket. The outer wall of the modular pressure block is fixedly connected with a notched push block. The number of notched push blocks on the outer wall of each set of modular pressure blocks is different, which is convenient to deal with the processing of different battery models.

[0013] Preferably, the placement bracket has a guide hole, a guide rod is slidably connected to the inner wall of the guide hole, a limit block is fixedly connected to the outer wall of the guide rod, the placement bracket has a movable groove, and the bottom of the limit block is slidably connected to the inner wall of the movable groove.

The outer wall of the toggle rod is slidably connected to the inner wall of the placement bracket. A toggle groove is provided on the top of the placement bracket. A toggle rod is slidably connected to the inner wall of the toggle groove.

[0015] This utility model provides a positioning device for processing lithium battery cells, which has the following advantages:

[0016] (1) Through the coordinated operation of the electric cylinder base, the push block, and the positioning structure, the placement seat can be adjusted by 90 degrees around the fixed axis, changing the position of the placement bracket to facilitate different processing needs. Furthermore, during the adjustment process, simply pull the lever upward to release the limit of the placement seat and then rotate it. Releasing the lever allows the compression spring to re-insert the insertion rod into the insertion hole for positioning. The operation is convenient and efficient, greatly improving the adaptability of the device to different processing conditions and its working efficiency.

[0017] (2) The modular pressure block on the insert is designed in a U-shape and is detachably connected.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0026] Please see Figures 1-4This utility model proposes a positioning device for processing lithium battery cells, including a base plate 1. A conveyor belt device is set in the middle of the base plate 1 to transport materials. This conveyor belt device is existing technology and will not be described in detail. A slide rail 2 is fixedly connected to the top of the base plate 1, and an electric cylinder seat 3 is fixedly connected to the top of the base plate 1. A push block 4 is fixedly connected to the output end of the electric cylinder seat 3. A sliding groove is opened at the bottom of the push block 4, and the inner wall of the sliding groove is slidably connected to the top of the slide rail 2. A positioning structure 5 is fixedly connected to the top of the push block 4. The slide rail 2, the electric cylinder seat 3, the push block 4, and the positioning structure 5 form a group, and two groups are provided in total.

[0027] In this utility model, the positioning structure 5 includes a placement plate 51. The bottom of the placement plate 51 is fixedly connected to the top of the push block 4. By starting the electric cylinder seat 3, the push block 4 can be moved on the slide rail 2, thereby moving the placement plate 51. The top of the push block 4 is fixedly connected to the placement plate 51. The top of the placement plate 51 is fixedly connected to the fixed shaft 52. The top of the fixed shaft 52 is slidably connected to the insertion block 53. The top of the fixed shaft 52 is provided with a square groove. The outer wall of the insertion block 53 is slidably connected to the inner wall of the square groove. The fixed shaft 52 and the insertion block 53 are elastically connected by a compression spring.

[0028] Furthermore, a synchronization plate 54 is fixedly connected to the top of the plug-in block 53, a pull rod 55 is fixedly connected to the top of the synchronization plate 54, and a plug-in rod 56 is fixedly connected to the bottom of the synchronization plate 54. A placement seat 57 is sleeved on the outer wall of the fixed shaft 52. The top of the placement seat 57 has four sets of plug-in holes arranged in a circumferential pattern. The plug-in rod 56 can be inserted into the plug-in holes. A placement bracket 58 is fixedly connected to the outer wall of the placement seat 57. Two sets of plug-in rods 56 are provided, and the bottom of both sets of plug-in rods 56 are inserted into the top of the placement seat 57. By pulling the pull rod 55 upward, the block can be driven... The synchronizing plate 54 moves upward, thereby driving the plug-in block 53 to move on the square groove. At the same time, the two sets of plug-in rods 56 will leave the plug-in hole. At this time, the limit of the placement seat 57 on the fixed shaft 52 is released. By rotating the placement seat 57, it can be rotated around the fixed shaft 52, thereby changing the angle of the placement seat 57. This device can perform 90-degree angle adjustment, which is convenient for changing the position of the placement bracket 58. Loosening the pull rod 55, the plug-in block 53 is reset by the reset of the compression spring, and the synchronizing plate 54 is reset at the same time. At this time, the two sets of plug-in rods 56 will be re-inserted into the plug-in hole.

[0029] Furthermore, the placement bracket 58 is provided with four sets, and modular pressure blocks 6 are detachably connected to the placement bracket 58. The modular pressure blocks 6 have a U-shaped design, and the inner wall of the modular pressure blocks 6 is snapped onto the outer wall of the placement bracket 58. The outer wall of the modular pressure blocks 6 is fixedly connected with notched push blocks. The number of notched push blocks on the outer wall of each set of modular pressure blocks 6 is different, which is convenient to deal with the processing of different battery models. For example, some models have two sets of batteries connected in parallel, and some have three sets of batteries connected in parallel.

[0030] Furthermore, the placement bracket 58 has a guide hole, and a guide rod 7 is slidably connected to the inner wall of the guide hole. A limit block 8 is fixedly connected to the outer wall of the guide rod 7. The placement bracket 58 has a movable groove, and the bottom of the limit block 8 is slidably connected to the inner wall of the movable groove. The guide rod 7 guides the movement of the limit block 8. The limit block 8 and the placement bracket 58 are elastically connected by a return spring. A toggle rod 9 is fixedly connected to the top of the limit block 8. The outer wall of the toggle rod 9 is slidably connected to the inner wall of the placement bracket 58. The top of the placement bracket 58 has a toggle groove, and the toggle rod 9 is slidably connected to the inner wall of the toggle groove. The return spring presses the limit block 8, so that part of the limit block 8 is located outside the placement bracket 58. At this time, the limit block 8 can limit the modular pressure block 6 that is stuck on the placement bracket 58, ensuring that the modular pressure block 6 is limited on the placement bracket 58.

[0031] In use, by activating the electric cylinder base 3, the push block 4 can be moved on the slide rail 2, which in turn moves the placement tray 51 closer to the conveyor belt device. The modular pressure block 6 on the placement bracket 58 facilitates the fixing of the product.

[0032] If other models of products need to be processed, by pulling the pull rod 55 upward, the synchronous plate 54 can be moved upward, which in turn moves the plug-in block 53 on the square groove. At the same time, the two sets of plug-in rods 56 will leave the plug-in hole. At this time, the limit of the placement seat 57 on the fixed shaft 52 is released. By rotating the placement seat 57, it can be rotated around the fixed shaft 52, thereby changing the angle of the placement seat 57 and moving the other set of modular pressure blocks 6 over. This facilitates the quick and easy completion of the device adjustment work and the processing of new products. Note that each modular pressure block 6 can correspond to one model.

[0033] By moving the lever 9, the limiting block 8 is slid. The guide rod 7 guides the movement of the limiting block 8. When the limiting block 8 is fully slid into the placement bracket 58, it is convenient and quick to replace the modular pressure block 6.

[0034] 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.
