Description

Technical Field

[0001] This utility model relates to a molding tool, specifically to an extrusion molding tool for an energy storage module. Background Technology

[0002] In the field of battery module forming and packaging, energy storage module forming tools are key equipment for extruding and fixing battery cell modules. Currently, existing energy storage module forming tools generally adopt a workbench model. The installation of these tools requires a large space and has a complex overall structure. Not only is the initial investment cost high, but the cost of repair and replacement is also relatively high if components are damaged during later use.

[0003] Meanwhile, due to limitations in their structure and installation methods, traditional workbench-style molding tools are difficult to move flexibly, operating only in fixed positions. They cannot freely adjust the work location according to production needs, making them highly dependent on available space and thus restricting production flexibility and efficiency to some extent. Furthermore, some traditional tools lack convenient pressure adjustment and monitoring functions, making it difficult to accurately control the extrusion pressure for battery cell modules with different string counts or specifications. This narrows their applicability and hinders improvements in the molding quality and production adaptability of energy storage modules.

[0004] Therefore, there is an urgent need for a molding tool that is simple in structure, low in cost, flexible and portable, and can meet the extrusion requirements of different battery cell modules, in order to solve the above-mentioned problems in the existing technology. Utility Model Content

Detailed Implementation

[0023] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0025] Referring to Figures 1, 2, and 3, this embodiment of the present invention provides an extrusion molding tool for energy storage modules, comprising:

[0026] The mounting frame includes two fixed end plates 7, four fixed screw rods 8, two battery cell support pieces 9, and a compression fixing plate 6;

[0027] Four fixing screws 8 are connected between the two fixed end plates 7; two battery cell support members 9 are connected between the two fixed end plates 7, and the battery cell support members 9 are provided with a notch for placing the bottom steel strip; the extrusion fixing plate 6 is connected to one of the fixed end plates 7.

[0028] Specifically, two fixed end plates 7 serve as the basic support structure, connected by four fixed lead screws 8 to form a stable frame structure, ensuring the overall rigidity and stability of the tool during extrusion and preventing deformation due to stress that could affect extrusion accuracy. Two cell support members 9 support the cell module; their notches allow for positioning of the bottom steel strip, facilitating the packing and securing of the cell module's bottom. The extrusion fixing plate 6 serves as a fixed reference surface during extrusion, providing support for one end of the cell module and working in conjunction with the subsequent extrusion moving components 4 to achieve the extrusion forming of the cell module.

[0029] An electrically controlled cylinder 3 is fixed to the fixed end plate 7. The movable push rod of the electrically controlled cylinder 3 is connected to the extrusion movable component 4. A space for accommodating the energy storage module is formed between the extrusion movable component 4 and the extrusion fixed plate 6.

[0030] Specifically, the electronically controlled cylinder 3 serves as the power source, and its stability during operation is ensured by fixing it to the fixed end plate 7.

[0031] The movable push rod is connected to the extrusion assembly 4, which transmits the power generated by the electronically controlled cylinder 3 to the extrusion assembly 4, causing the extrusion assembly 4 to move towards the extrusion fixed plate 6. The space formed between the two is used to place the energy storage module to be processed. The movement of the extrusion assembly 4 realizes the extrusion operation of the energy storage module in the space, thereby compactly combining the battery cells together.

[0032] The control box 1 is mounted on the electrically controlled cylinder 3 via the control box fixing component 2. The control box fixing component 2 securely mounts the control box 1 onto the electrically controlled cylinder 3, saving space and facilitating operation by the operator. The control box 1 integrates a control circuit, which can control the start and stop of the electrically controlled cylinder 3, realizing automated control of the extrusion process and improving the convenience and safety of operation.

[0033] In this embodiment, the mounting bracket further includes a side stop bar 10, which is connected between the two fixed end plates 7 to limit the placement position of the battery cell.

[0034] Specifically, the side baffle 10 is connected between the two fixed end plates 7, forming a limiting structure for the side of the battery cell module. When placing the battery cell module, the side baffle 10 can prevent the battery cell module from shifting to the sides, ensuring that the battery cell module can be accurately placed in the preset extrusion position, ensuring that all battery cells are in the same plane, and avoiding uneven extrusion force due to the misalignment of the battery cells, which would affect the molding quality of the energy storage module.

[0035] In this embodiment, the electronically controlled cylinder 3 is equipped with a pressure regulating valve and a pressure display.

[0036] Specifically, the pressure regulating valve can adjust the output pressure of the electronically controlled cylinder 3 according to the extrusion pressure requirements of battery cell modules of different specifications and series numbers. This ensures that the extrusion pressure is sufficient to compactly form the battery cell modules without damaging the cells due to excessive pressure. The pressure display can show the current extrusion pressure value in real time, allowing operators to intuitively understand the extrusion situation and make precise adjustments according to actual needs, ensuring the controllability and consistency of the extrusion process.

[0037] In this embodiment, the control box 1 is provided with two start buttons and an emergency stop button. The two start buttons are used to start the molding tool when pressed simultaneously; the emergency stop button is used to stop the molding tool in an emergency.

[0038] Specifically, the system features two start buttons that must be pressed simultaneously to activate the equipment. This prevents accidental start-up due to a single button press, improving operational safety and preventing personal injury or equipment damage caused by misoperation. The emergency stop button quickly cuts off the power supply to the equipment in case of abnormal conditions (such as incorrect battery cell placement or unusual noises), immediately halting operation and allowing operators to address the issue promptly, thus reducing the risk of accidents.

[0039] In this embodiment, the extrusion movable assembly 4 includes an extrusion movable plate 41 and an extrusion guide rod 42. The extrusion movable plate 41 is connected to the movable push rod of the electronically controlled cylinder 3, and the extrusion guide rod 42 is connected between the extrusion movable plate 41 and a fixed end plate 7.

[0040] Specifically, the extrusion plate 41 is connected to the movable push rod of the electronically controlled cylinder 3, directly contacting the energy storage module and transmitting extrusion force. Its flat surface ensures uniform extrusion of the battery cell module. The extrusion guide rod 42 plays a guiding role during the movement of the extrusion plate 41, limiting the movement direction of the extrusion plate 41 and ensuring that it can only move along a preset straight line. This prevents the extrusion plate 41 from shifting or tilting during the extrusion process, ensuring the verticality and accuracy of the extrusion, and thus ensuring that the forming dimensions of the energy storage module meet the requirements.

[0041] In this embodiment, a protective plate 5 is also included. The protective plate 5 is installed on the outside of the fixed end plate 7 corresponding to the cell extrusion operation area. The protective plate 5 is made of insulating material.

[0042] Specifically, the protective plate 5 is installed in the area corresponding to the cell extrusion operation. It can block potentially flying debris during the extrusion process or prevent operators from accidentally contacting the extrusion components, thus providing physical protection. Made of insulating material, it can effectively prevent electric shock accidents to operators due to equipment leakage or charged cells during operation, further improving the safety of tool use.

[0043] The usage process of this utility model is as follows: First, preliminary preparation: first place the bottom steel strip into the notches at both ends of the cell support component 9, and then place the end plate and the cell with the insulation board attached in sequence in the space between the extrusion fixing component and the extrusion moving component 4 to ensure that the cell is placed neatly.

[0044] Second, equipment start-up: The operator presses the start button on the control box 1 at the same time. The control box 1 then controls the electric cylinder 3 to start. The movable push rod of the electric cylinder 3 will push the extrusion movable component 4 to move towards the extrusion fixed plate 6 to extrude the battery cell module.

[0045] Third, pressure control: During the extrusion process, the extrusion pressure can be adjusted by the pressure regulating valve configured in the electronically controlled cylinder 3. At the same time, the current extrusion pressure value can be observed in real time with the help of the pressure display to ensure that the extrusion pressure meets the requirements of the cell module forming.

[0046] Fourth, packaging operation: After the battery cell module is squeezed to the required size, manually put the upper and lower steel strips on the battery cell module to complete the initial packaging operation.

[0047] Fifth, stop the extrusion: Press the emergency stop button, the movable push rod of the electronically controlled cylinder 3 drives the extrusion movable component 4 to reset, the extrusion pressure is released, and the extrusion and packaging process of the battery cell module is completed.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
