Description

Technical Field

[0001] This utility model relates to the field of lithium battery PACK processing technology, specifically a cutting device for the cable tray of an epoxy board for lithium battery PACK. Background Technology

[0002] A lithium battery pack is a battery system that combines multiple individual lithium batteries through an integrated design. Its core components include individual battery cells, a BMS management system, structural components, electrical connectors, and thermal management components. In the lithium battery pack assembly process, the cells are assembled in series or parallel. In order to fix the battery and protection board and prevent short circuits between the battery pack and the external metal casing, insulating materials such as epoxy board are used to wrap the battery module. This is crucial to the performance and safety of the battery pack. Since different models of battery packs have different requirements for wiring methods, and each model requires slots to be cut on the epoxy board for arranging the positive and negative electrode lines, sampling lines and temperature control lines, the size and position of these slots directly affect the reliability and assembly efficiency of the wiring harness. Currently, the fabrication of wiring channels on epoxy boards typically employs either pre-processing or manual cutting. Each method has its advantages and disadvantages. Pre-processing requires detailed modeling and prototyping to plan the wiring routing of the battery pack and create fabrication drawings for the epoxy board with the wiring channels. This process is not only complex and time-consuming, but may also deviate from the actual wiring requirements in production, necessitating adjustments to the wiring layout later, leading to readjustments or the addition of wiring channels, thus increasing production and time costs. Manual cutting of wiring channels, on the other hand, easily results in non-standard channels, posing a risk of burrs scratching the wire harness, and also has relatively low production efficiency, making it difficult to meet the quality consistency requirements of mass production. Utility Model Content

[0003] The purpose of this invention is to provide a cutting device for the cable tray of an epoxy board in a lithium battery pack, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A lithium battery PACK epoxy board cable tray cutting device, comprising: A cutting stand has a first square through hole extending to the bottom at the top, and a cutting head is provided above the first square through hole. A V-shaped cut is provided at the bottom end of the cutting head. The feed inlet is located at the middle of the front and rear of the cutting seat, and the feed inlet is connected to the first square through hole; A lifting assembly for lifting the cutting head, the lifting assembly including a floating block connected to the cutting head; A fixing component for fixing the cutting seat, the fixing component including a fixing plate disposed at the bottom of the cutting seat.

[0005] Preferably, the cutting seat is fixed to the center of the fixing plate by bolts, and the fixing plate has a vertical through hole at the position corresponding to the first square through hole.

[0006] Preferably, the upper end of the fixing plate is provided with a vertical plate, which is fixed to the fixing plate by bolts, and there are two sets of vertical plates, which are symmetrically distributed with the cutting seat as the center.

[0007] Preferably, the lifting assembly includes a cylinder installed between the two sets of vertical plates, and a connecting bolt is connected to the cylinder shaft.

[0008] Preferably, a U-shaped through hole is provided at the upper end of the floating block corresponding to the position of the connecting bolt, and a second square through hole is provided at the lower end of the U-shaped through hole; Both the second square through hole and the U-shaped through hole penetrate the side wall of the floating block.

[0009] Preferably, the end of the connecting bolt away from the cylinder passes through the U-shaped through hole and is engaged inside the second square through hole.

[0012] Preferably, rubber feet are provided at all four corners of the lower end face of the positioning plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This utility model uses the cooperation of a cylinder, connecting bolts, and a floating block to drive the cutting head to move up and down in the first square through hole of the cutting seat. Under the shearing action of the V-shaped cutting edge on the cutting head and the intersection line of the feed port and the square through hole on the cutting seat, the epoxy board placed in the feed port is cut.

[0015] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0017] like Figures 1-6 As shown, this application provides a lithium battery PACK epoxy board cable tray cutting device, including a fixing plate 1. The fixing plate 1 is a hollow rectangular plate with a first through hole running vertically through it in the middle. Screw through holes for installing the cutting seat 2, the upright plate 7 and the positioning plate 8 are distributed sequentially on the outside of the first through hole.

[0018] Specifically, such as Figures 2-3 As shown, the cutting seat 2 installed on the fixed plate 1 is a cuboid, and a first square through hole 2-1 extending to the bottom is provided at the center of its upper part. The size and position of the first square through hole 2-1 match the first through hole vertically penetrating on the fixed plate 1. The cutting seat 2 is processed with a horizontally penetrating "匚"-shaped feeding port 2-2 at the front-back middle position, making it look like a "工" shape when viewed from the side. This feeding port intersects with the square through-hole penetrating from top to bottom, forming a right-angle edge.

[0019] Specifically, as Figures 4-5 shown, a cutting head 3 is arranged above the cutting seat 2. The outline and dimensions of its top view are exactly matched with the first square through-hole 2-1 on the cutting seat 2. Thus, the cutting head 3 can be smoothly inserted into the first square through-hole 2-1 of the cutting seat 2 and can move up and down along the first square through-hole 2-1. A V-shaped notch 3-1 penetrating in the front-back direction is provided at the bottom end of the cutting head 3. When the cutting head 3 moves up and down, this notch can interact with the right-angle edge of the cutting seat 2 to form a shearing structure similar to scissors.

[0020] Specifically, as Figures 1-2 and Figure 4 shown, above the cutting head 3 is a floating block 4. A second square through-hole 4-1 is opened on one side of the upper end of the floating block 4, and a U-shaped through-hole 4-2 is opened at the top end inside the second square through-hole 4-1. The screw part of the connecting bolt 5 is inserted from the opening position of the U-shaped through-hole 4-2, and the bolt head is placed in the second square through-hole 4-1 with a certain gap, so that the connecting bolt 5 has a certain offset in the second square through-hole 4-1. [[ID=!15]]

[0021] The screw part of the connecting bolt 5 is installed on the cylinder shaft of the cylinder 6, and the cylinder 6 is installed on the fixed plate 1 through two left-right vertical plates 7, forming an externally enclosed whole. When the cylinder shaft extends, the connecting bolt 5 moves downward, pressing against the cutting head 3, causing the cutting head 3, the floating block 4, and the connecting bolt 5 to move downward together along the first square through-hole 2-1 of the cutting seat 2. When the cylinder shaft retracts, the connecting bolt 5 moves upward, and the whole moves upward together.

[0022] Specifically, as Figure 1 and Figure 6 shown, the lower part of the vertical plate 7 is provided with a notch matching the feeding port 2-2, making it easy to put the epoxy board into the feeding port 2-2 and fit it to the vertical surface of the feeding port 2-2. When the cutting head 3 moves downward along the square through-hole of the cutting seat 2, the edge of the V-shaped notch 3-1 and the right-angle edge of the cutting seat 2 form a shearing structure, and the epoxy board is cut under the action of the cylinder 6. When the cutting head 3 continues to move downward to reach the bottom surface of the cutting seat 2, the cut epoxy board waste is pushed out of the first square through-hole 2-1. <L

[0023] The second through hole in the middle of the positioning plate 8 fits the main component in the middle and is installed by screws. The upper surface of the positioning plate 8 is flush with the lower surface of the matching notch of the feed port 2-2 and the vertical plate 7. The positioning plate 8 is provided with two horizontal grooves and a scale 9 is installed thereon. The upper surface of the scale 9 is flush with the upper surface of the positioning plate 8. The epoxy board is smoothly inserted into the feed port 2-2 and fits against the vertical surface of the feed port 2-2 to achieve front and back positioning. Then it is placed on the upper surface of the positioning plate 8. The left and right positions of the epoxy board are adjusted by observing the scale to achieve left and right positioning.

[0024] In addition, rubber feet 10 are installed at the four corners of the positioning plate 8 to raise the device and make a sufficient gap between the fixing plate 1 and the tabletop, so that the cut epoxy board waste can be discharged from the device through the first through hole.

[0025] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary; within the framework of this invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this invention as described above, which are not provided in the details for the sake of brevity.

[0026] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
