Description
Technical Field
[0001] This utility model relates to the technical field of lithium battery production, and in particular to a cell vacuum sealing device. Background Technology
[0002] The cell vacuum sealing device is a key piece of equipment used in the lithium battery production process, especially after the liquid injection process, where the battery needs to be sealed to ensure the internal sealing and performance of the battery. The device usually includes a vacuum chamber and a sealing device. During operation, the aluminum-plastic film is heated and pressurized by sealing and evacuating the vacuum chamber and heating and pressurizing the sealing device to achieve vacuum sealing of the cell, thereby preventing leakage of the lithium battery when it is put into the market.
[0003] Currently available battery cell vacuum sealing devices have the following problems: During the heating and pressurization process of the battery cell aluminum-plastic film, residues of aluminum-plastic film material, thermally conductive materials, scale, or electrolyte may remain in the device. These devices require timely maintenance and cleaning after a period of use to reduce the impact of residues on heat conduction and vacuuming functions. However, in current battery cell vacuum sealing devices, the vacuum chamber is typically open at the bottom. The vacuum chamber moves vertically to form a vacuum-sealed area with a horizontal tray supporting the battery cells before vacuuming and sealing. This design results in an overly compact structure between the vacuum chamber, the horizontal tray in the liquid injection production line, and the sealing device, making maintenance work difficult and requiring disassembly and reassembly of the vacuum chamber and sealing device for cleaning. This increases the workload for maintenance personnel and urgently needs to be addressed. Utility Model Content
[0004] To address the shortcomings of the prior art, this application provides a battery cell vacuum sealing device.
[0005] The above-mentioned inventive objective of this application is achieved through the following technical solutions:
[0006] A battery cell vacuum sealing device includes a frame, a first lifting cylinder, a vacuum sealing chamber, and a conveying plate. The first lifting cylinder is vertically mounted on the frame. The vacuum sealing chamber has an open bottom and its top is fixedly connected to the piston rod of the first lifting cylinder. The conveying plate is provided with a workstation for vertically placing the battery cells. The conveying plate circulates around the frame via a conveying device. There is a closed position on the moving path of the vacuum sealing chamber. When the vacuum sealing chamber is in the closed position and the conveying plate carries the battery cells directly below the vacuum sealing chamber, a closed cavity is formed between the vacuum sealing chamber and the conveying plate. The vacuum sealing chamber has an air extraction port connected to an air pump. The vacuum sealing chamber has a plurality of sealing modules for sealing the battery cells corresponding to the number of battery cells inside. The frame is provided with a flipping mechanism for driving the first lifting cylinder to rotate.
[0007] By adopting the above technical solution, during operation, the first lifting cylinder drives the piston rod to lift the vacuum sealing box, forming a closed cavity with the conveyor plate. This ensures the battery cell is in a stable and controlled environment. Then, an air pump evacuates the sealed cavity through the extraction port, followed by sealing the battery cell using a sealing module. When maintenance and cleaning are required, the tilting mechanism drives the first lifting cylinder to rotate the vacuum sealing box. By rotating the vacuum sealing box until its bottom opening faces horizontally, and with the first lifting cylinder driving the piston rod to move the vacuum sealing box horizontally, the vacuum sealing box and its internal sealing module can be removed from the compact space of the liquid injection production line. This allows maintenance personnel to perform maintenance and cleaning on a slightly farther working surface than the liquid injection production line, eliminating the need for disassembly and thus improving the convenience of maintenance work, increasing the efficiency of maintenance personnel, and reducing their workload.
[0008] In a preferred embodiment, the present application may be further configured such that: the flipping mechanism includes a flipping mounting plate and a servo motor, the flipping mounting plate is rotatably connected to the frame, the servo motor is fixedly mounted on the frame, the output shaft of the servo motor is fixedly connected to the flipping mounting plate, and the first lifting cylinder is fixedly mounted on the flipping mounting plate.
[0009] By adopting the above technical solution and setting a flip-mounting plate, a stable mounting position can be provided for the first lifting cylinder, and the output shaft of the servo motor can be directly connected to the flip-mounting plate so that the servo motor can directly control the flip-mounting plate to rotate, thereby realizing the joint rotation of the first lifting cylinder, the vacuum sealing box and its internal sealing module.
[0010] In a preferred embodiment, the present application may be further configured such that the flipping mechanism further includes a rotation limit seat and a guide rod, the rotation limit seat is fixedly installed on the frame and has an arc-shaped limit hole, one end of the guide rod is fixedly connected to the flipping mounting plate and the other end passes through the arc-shaped limit hole.
[0011] By adopting the above technical solution, when the servo motor drives the flip mounting plate to rotate, the rotation limit seat, together with its arc-shaped limit hole and guide rod, can provide guidance and limit for the flip mounting plate, thereby improving the stability of the flip mounting plate driving the first lifting cylinder, the vacuum sealing box and its internal sealing module to rotate together.
[0012] In a preferred embodiment, the sealing module may be further configured as follows: the sealing module includes a second lifting cylinder, a lifting and hot-pressing linkage assembly, and two hot-pressing sealing blocks arranged opposite each other. The second lifting cylinder is vertically installed and extends through the top of the vacuum sealing box. Both hot-pressing sealing blocks are connected to the second lifting cylinder and have heating elements inside. The heating elements are used to heat the hot-pressing sealing blocks. The lifting and hot-pressing linkage assembly is connected to the second lifting cylinder and drives the two hot-pressing sealing blocks to move towards or away from each other when the second lifting cylinder drives the piston rod to move the two hot-pressing sealing blocks downward or upward.
[0013] By adopting the above technical solution, after the vacuum sealing box forms a closed cavity and completes the vacuuming process, the second lifting cylinder drives two opposing hot-press sealing blocks to move downwards towards the battery cell bag on the workstation seat. At the same time, the lifting hot-press linkage component drives the two hot-press sealing blocks to move towards each other until the two hot-press sealing blocks abut against the opposite sides of the battery cell bag. Then, the hot-press sealing blocks are heated by the heating element to complete the hot-press sealing operation of the battery cell bag. By setting the lifting hot-press linkage component, the two opposing hot-press sealing blocks can perform dual-axis movement synchronously, which can improve the sealing efficiency of the battery cell bag.
[0014] In a preferred embodiment, the present application may be further configured as follows: the lifting and hot-pressing linkage assembly includes a lifting moving frame and a connecting plate, both of which are fixedly connected to the piston rod of the second lifting cylinder. The connecting plate has two symmetrical and inclined strip-shaped sliding holes, and a slider is slidably disposed in the strip-shaped sliding holes. The two hot-pressing sealing blocks are respectively fixedly connected to the two sliders and are slidably connected to the lifting moving frame.
[0015] By adopting the above technical solution, when the piston rod driven by the second lifting cylinder moves downward, it will drive the lifting moving frame and the connecting plate to move downward synchronously. At this time, the connecting plate abuts against the slider located in the strip sliding hole. Since the strip sliding hole is inclined, the slider will generate horizontal displacement synchronously during the downward movement, so as to drive the hot-press sealing block fixedly connected to it to generate horizontal displacement synchronously on the lifting moving frame, thereby realizing the synchronous lifting and horizontal movement of the hot-press sealing block and improving the sealing efficiency of the battery cell.
[0016] In a preferred embodiment, this application can be further configured such that: the lifting and moving frame is provided with a guide rail, and both of the hot-press sealing blocks are slidably connected to the guide rail.
[0017] By adopting the above technical solution and setting guide rails, the hot-press sealing block can be guided and its sliding stability can be improved.
[0018] In summary, this application includes at least one of the following beneficial technical effects:
[0019] 1. During operation, the first lifting cylinder drives the piston rod to raise and lower the vacuum sealing box, forming a closed cavity with the conveyor plate. This ensures the battery cell is in a stable and controlled environment. A vacuum is then created in the sealed cavity through the air extraction port using an air pump. The battery cell is then sealed using a sealing module, completing the vacuum sealing process. When maintenance and cleaning are required, the tilting mechanism drives the first lifting cylinder to rotate the vacuum sealing box. The box is rotated until its bottom opening faces horizontally. At this point, the first lifting cylinder drives the piston rod to move the vacuum sealing box horizontally, allowing it and its internal sealing module to be removed from the compact space of the liquid injection production line. This allows maintenance personnel to perform maintenance and cleaning on a slightly farther surface than the production line, eliminating the need for disassembly and thus improving the convenience of maintenance work, increasing the efficiency of maintenance personnel, and reducing their workload.
[0020] 2. By setting a flip mounting plate, a stable mounting position can be provided for the first lifting cylinder, and the output shaft of the servo motor can be directly connected to the flip mounting plate so that the servo motor can directly control the rotation of the flip mounting plate, thereby realizing the joint rotation of the first lifting cylinder, the vacuum sealing box and its internal sealing module.
[0021] 3. After the vacuum sealing chamber forms a closed cavity and the vacuuming process is completed, the second lifting cylinder drives two opposing hot-press sealing blocks to move downwards towards the battery cell bag on the workstation. At the same time, the lifting hot-press linkage component drives the two hot-press sealing blocks to move towards each other until the two hot-press sealing blocks abut against the opposite sides of the battery cell bag. Then, the hot-press sealing blocks are heated by the heating element to complete the hot-press sealing operation of the battery cell bag. By setting the lifting hot-press linkage component, the two opposing hot-press sealing blocks can perform dual-axis movement synchronously, which can improve the sealing efficiency of the battery cell bag.

[0031] The following is a reference appendix. Figure 1 To be continued Figure 5 This application describes a battery cell vacuum sealing device.
[0032] like Figure 1 , Figure 2 and Figure 3As shown, the battery cell vacuum sealing device includes a frame 1, a first lifting cylinder 2, a vacuum sealing chamber 3, and a conveying plate 4. The first lifting cylinder 2 is vertically mounted on the frame 1. The vacuum sealing chamber 3 has an open bottom and is fixedly connected to the piston rod of the first lifting cylinder 2 at the top. The conveying plate 4 is provided with a workstation 6 for vertically placing the battery cell 5. The conveying plate 4 circulates around the frame 1 via a conveying device 7. There is a closed position on the moving path of the vacuum sealing chamber 3. When the vacuum sealing chamber 3 is in the closed position and the conveying plate 4 carries the battery cell 5 to directly below the vacuum sealing chamber 3, a closed cavity is formed between the vacuum sealing chamber 3 and the conveying plate 4. The vacuum sealing chamber 3 has an air extraction port 8 connected to an air pump. The vacuum sealing chamber 3 is provided with several sealing modules 9 for sealing the battery cells 5, corresponding to the number of battery cells 5. The frame 1 is provided with a flipping mechanism 10, which drives the first lifting cylinder 2 to rotate. During operation, the first lifting cylinder 2 is controlled to drive the piston rod of the first lifting cylinder 2 to rotate. The piston rod drives the vacuum sealing chamber 3 to rise and fall, forming a closed cavity with the conveyor plate 4, so that the battery cell 5 can be in a stable and controlled environment. Then, the air pump is used to evacuate the closed cavity through the air extraction port 8, and then the sealing module 9 seals the battery cell 5 to complete the vacuum sealing process. When maintenance and cleaning are required, the flipping mechanism 10 can drive the first lifting cylinder 2 to rotate the vacuum sealing chamber 3. By rotating the vacuum sealing chamber 3 until its bottom opening faces the horizontal direction, the first lifting cylinder 2 can drive the piston rod to move the vacuum sealing chamber 3 horizontally, so that the vacuum sealing chamber 3 and its internal sealing module 9 can be removed from the compact space of the liquid injection production line. This makes it easier for maintenance personnel to maintain and clean the vacuum sealing chamber 3 and its internal sealing module 9 from a working surface slightly away from the liquid injection production line without disassembly, thereby improving the convenience of maintenance work, improving the work efficiency of maintenance personnel and reducing their workload.
[0033] Specifically, in actual operation, the first lifting cylinder 2 plays a dual role: when the first lifting cylinder 2 is in a vertical state, it can drive the piston rod to lift the vacuum sealing box 3 to cooperate with the conveyor plate 4 to form a closed cavity, so that the battery cell 5 can be in a stable and controlled environment, which is convenient for vacuuming and sealing. When the first lifting cylinder 2 is in a horizontal state, it can drive the piston rod to move the vacuum sealing box 3 in the horizontal direction, so that the vacuum sealing box 3 and its internal sealing module 9 can be removed from the compact space of the liquid injection production line, which is convenient for maintenance personnel to maintain and clean the vacuum sealing box 3 and its internal sealing module 9 from a working surface slightly away from the liquid injection production line.
[0034] It should be noted that the conveying device 7 can be a conventional conveying equipment on the market, such as an electric track module or a belt conveyor module. In addition, the conveying device 7 can also be equipped with other devices required for other processes on the liquid injection production line, such as a flaring device or a liquid injection device, so as to realize the cyclic movement and conveying of the conveying plate 4 on the liquid injection production line. The air pump can be a conventional vacuum pump on the market, which will not be elaborated here.
[0035] Specifically, such as Figure 2 and Figure 4 As shown, the flipping mechanism 10 includes a flipping mounting plate 101 and a servo motor 102. The flipping mounting plate 101 is rotatably connected to the frame 1, and the servo motor 102 is fixedly mounted on the frame 1. Specifically, the output shaft of the servo motor 102 is fixedly connected to the flipping mounting plate 101, and the first lifting cylinder 2 is fixedly mounted on the flipping mounting plate 101. By setting the flipping mounting plate 101, a stable mounting position can be provided for the first lifting cylinder 2, and the output shaft of the servo motor 102 is directly connected to the flipping mounting plate 101 so that the servo motor 102 directly controls the flipping mounting plate 101 to rotate, thereby realizing the joint rotation of the first lifting cylinder 2, the vacuum sealing box and the sealing module 9 inside it.
[0036] Furthermore, the flipping mechanism 10 also includes a rotation limit seat 103 and a guide rod 104. The rotation limit seat 103 is fixedly installed on the frame 1 and has an arc-shaped limit hole 105. One end of the guide rod 104 is fixedly connected to the flipping mounting plate 101 and the other end passes through the arc-shaped limit hole 105. When the servo motor 102 drives the flipping mounting plate 101 to rotate, the rotation limit seat 103, together with its arc-shaped limit hole 105 and the guide rod 104, can provide guidance and limit for the flipping mounting plate 101, thereby improving the stability of the flipping mounting plate 101 driving the first lifting cylinder 2, the vacuum sealing box and its internal sealing module 9 to rotate together.
[0037] In addition, such as Figure 4 and Figure 5As shown, in one embodiment, the sealing module 9 includes a second lifting cylinder 91, a lifting and hot-pressing linkage assembly 92, and two hot-pressing sealing blocks 93 arranged opposite each other. The second lifting cylinder 91 is vertically installed and extends through the top of the vacuum sealing box 3. Both hot-pressing sealing blocks 93 are connected to the second lifting cylinder 91 and are equipped with heating elements (not shown in the figure) inside. The heating elements are used to heat the hot-pressing sealing blocks 93. The heating elements can be heating elements such as heating wires or heating rods. The lifting and hot-pressing linkage assembly 92 is connected to the second lifting cylinder 91. When the second lifting cylinder 91 drives the piston rod to move the two hot-pressing sealing blocks 93 downward or upward, it drives the two hot-pressing sealing blocks 93 to move towards each other or towards each other. In the back-movement process, after the vacuum sealing chamber 3 forms a closed cavity and completes the vacuuming process, the second lifting cylinder 91 drives two opposing hot-press sealing blocks 93 to move downwards towards the battery cell 5 bag on the workstation seat 6. At the same time, the lifting hot-press linkage component 92 drives the two hot-press sealing blocks 93 to move towards each other until the two hot-press sealing blocks 93 respectively abut against the opposite sides of the battery cell 5 bag. Then, the hot-press sealing blocks 93 are heated by the heating element to complete the hot-press sealing operation of the battery cell 5 bag. By setting the lifting hot-press linkage component 92, the two opposing hot-press sealing blocks 93 can perform dual-axis movement operations synchronously, which can improve the sealing efficiency of the battery cell 5 bag.
[0038] Specifically, the lifting and hot-pressing linkage assembly 92 includes a lifting moving frame 921 and a connecting plate 922. Both the lifting moving frame 921 and the connecting plate 922 are fixedly connected to the piston rod of the second lifting cylinder 91. The connecting plate 922 has two symmetrically arranged and inclined strip-shaped sliding holes 923. A slider 924 is slidably arranged in the strip-shaped sliding holes 923. Two hot-pressing sealing blocks 93 are respectively fixedly connected to the two sliders 924 and are slidably connected to the lifting moving frame 921. The piston rod is driven by the second lifting cylinder 91. When moving downwards, the lifting frame 921 and the connecting plate 922 will move downwards synchronously. At this time, the connecting plate 922 abuts against the slider 924 located in the strip sliding hole 923. Since the strip sliding hole 923 is inclined, the slider 924 will generate horizontal displacement synchronously during the downward movement, so as to drive the hot-press sealing block 93 fixedly connected to it to generate horizontal displacement synchronously on the lifting frame 921, thereby realizing the synchronous lifting and horizontal movement of the hot-press sealing block 93, improving the sealing efficiency of the battery cell 5.
[0039] Furthermore, the lifting and moving frame 921 is provided with a guide rail 11, and both hot-press sealing blocks 93 are slidably connected to the guide rail 11. By providing the guide rail 11, the hot-press sealing blocks 93 can be guided and their sliding stability can be improved.
[0040] The implementation principle of the battery cell vacuum sealing device in this application embodiment is as follows: When maintenance and cleaning are required, the servo motor 102 is started to control the flip mounting plate 101 to drive the first lifting cylinder 2, the vacuum sealing box and its internal sealing module 9 to rotate together, so that the vacuum sealing box 3 rotates to the bottom opening facing the horizontal direction. Then, the piston rod driven by the first lifting cylinder 2 drives the vacuum sealing box 3 to move horizontally, so that the vacuum sealing box 3 and its internal sealing module 9 can be separated from the compact space of the liquid injection production line. This makes it convenient for maintenance personnel to perform maintenance and cleaning on the vacuum sealing box 3 and its internal sealing module 9 on the working surface slightly away from the liquid injection production line without disassembly and assembly, thereby improving the convenience of maintenance work, thereby improving the work efficiency of maintenance personnel and reducing the workload of maintenance personnel.
[0041] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
