Description

Technical Field

[0001] This utility model relates to a pressing equipment for lithium battery production, belonging to the field of lithium battery processing technology. Background Technology

[0002] Battery electrodes are made by bonding various metal foils one by one with a conductive slurry. Different conductive requirements necessitate different metal foils for lithium battery electrodes. During the manufacturing process, the metal foils need to be cut into square blocks, coated with the conductive slurry, and then bonded together. The resulting electrode pre-finished product cannot be used directly; it needs to be heated and compacted to ensure that the metal foils can be stably bonded together and exhibit good conductivity. Therefore, electrode pressing equipment is required for the pressing operation. Existing pressing equipment mainly consists of a hydraulic press and a heating mold. The pre-finished product is placed in the heating mold, and the top rod of the hydraulic press is moved down. The pressure plate at the bottom of the top rod presses down on the pre-finished product in the heating mold. Under the action of heating and pressure, the metal foils bond more tightly together, and the conductive slurry can effectively bond the metal foils together.

[0003] In existing lithium battery production pressing equipment, workers need to control the lifting and lowering of the hydraulic press, and only one pressing sheet can be placed into the heating mold at a time, resulting in low processing efficiency and low operational safety.

[0004] This utility model proposes a new solution to the above problems. Utility Model Content

[0005] The main purpose of this utility model is to solve the problems of low processing efficiency and low operational safety caused by the need for workers to control the lifting and lowering of hydraulic presses, and the fact that only one sheet can be placed into the heating mold at a time. Therefore, this utility model provides a sheet pressing device for lithium battery production.

[0006] The objective of this utility model can be achieved by adopting the following technical solution:

[0007] A lithium battery pressing device includes a heating table, a rotating seat on the upper surface of the heating table, a limit frame fixedly connected to the upper surface of the rotating seat, a discharge hole on the upper surface of the rotating seat, a transmission box fixedly connected to the upper surface of the heating table, a drive motor fixedly connected to the lower surface of the transmission box, a gear rotatably connected to the inner wall of the transmission box, and a transmission tooth groove provided on the inner wall of the rotating seat.

[0008] Preferably, the rotating seat has a circular hole at its center, and the surface of the rotating seat is provided with a wear-resistant layer.

[0009] Preferably, the limiting frame is arranged in a circular array on the upper surface of the rotating seat, and the lower surface of the heating platform is fixedly connected with a support leg.

[0010] Preferably, the discharge hole is located below the limiting frame, and the shape of the discharge hole is adapted to the limiting frame.

[0011] Preferably, the output end of the drive motor passes through the transmission box and is fixedly connected to the gear, and the gear is connected to the transmission tooth groove.

[0012] Preferably, an outer limiting ring is fixedly connected to the upper surface of the heating platform, and the inner wall of the outer limiting ring is slidably connected to the rotating seat.

[0013] Preferably, an inner limiting ring is fixedly connected to the upper surface of the heating platform, and the surface of the inner limiting ring is slidably connected to the rotating seat.

[0014] Preferably, the inner limiting ring has a notch, and the surface of the transmission box is fixedly connected to the notch of the inner limiting ring.

[0015] Preferably, the upper surface of the heating table is provided with a material discharge groove, and the position of the material discharge groove is adapted to the limiting frame.

[0016] Preferably, the heating table has a mounting groove at its center, a connecting frame is fixedly connected to the inner wall of the mounting groove, a hydraulic rod is fixedly connected to the surface of the connecting frame, and a pressure plate is fixedly connected to the output end of the hydraulic rod.

[0017] The beneficial technical effects of this utility model are as follows: By placing the raw material inside the limiting frame, the drive motor drives the gear to rotate, and the gear and transmission tooth groove transmit power, thereby driving the rotating seat to rotate. The raw material moves under the restriction of the limiting frame and the discharge hole, and moves the raw material to the pressurizing position for pressurization. The placement of the raw material and the pressing of the raw material can be carried out simultaneously, improving the tableting efficiency of the raw material. The placement position and the pressurizing position are staggered, and when the raw material is pressurized, the operator stays away from the pressure plate, improving the safety of the device.

[0024] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0025] like Figures 1-5 As shown in the figure, this embodiment provides a lithium battery production pressing equipment, including a heating table 1. A rotating seat 2 is provided on the upper surface of the heating table 1. A limiting frame 4 is fixedly connected to the upper surface of the rotating seat 2. When the raw material is pressurized, the limiting frame 4 restricts the position of the raw material, making it less likely to shift. A discharge hole 5 is opened on the upper surface of the rotating seat 2, which is connected to the top of the heating table 1. Therefore, the bottom of the raw material is supported by the heating table 1, and the heating table 1 can directly heat the raw material. A transmission box 6 is fixedly connected to the upper surface of the heating table 1. A drive motor 7 is fixedly connected to the lower surface of the transmission box 6. A gear 8 is rotatably connected to the inner wall of the transmission box 6. The output end of the drive motor 7 passes through the transmission box 6 and is fixedly connected to the gear 8. The gear 8 is connected to the transmission tooth groove 9. The inner wall of the rotating seat 2 is provided with the transmission tooth groove 9. A circular hole 3 is provided in the center of the rotating seat 2. A wear-resistant layer is provided on the surface of the rotating seat 2. The wear-resistant layer improves the wear resistance of the rotating seat 2 and helps to extend the service life of the rotating seat 2. The limiting frame 4 is distributed in a circular array on the upper surface of the rotating seat 2. The raw material can be placed and the raw material can be pressed into tablets at the same time, which improves the tableting efficiency of the raw material. The lower surface of the heating table 1 is fixedly connected to the support leg 16. The discharge hole 5 is located below the limiting frame 4, and the shape of the discharge hole 5 is adapted to the limiting frame 4. First, the heating table 1 is turned on to preheat the rotating seat 2 and the limiting frame 4. Then, the raw material is put into the limiting frame 4. The drive motor 7 drives the gear 8 to rotate. The gear 8 and the transmission tooth groove 9 transmit power, thereby driving the rotating seat 2 to rotate. The raw material moves first under the restriction of the limiting frame 4 and the discharge hole 5. The raw material is moved to the pressurization position and pressurized.

[0026] In this embodiment, as Figure 1 , Figure 3and Figure 4 As shown, an outer limiting ring 10 is fixedly connected to the upper surface of the heating platform 1. The inner wall of the outer limiting ring 10 is slidably connected to the rotating seat 2. An inner limiting ring 11 is fixedly connected to the upper surface of the heating platform 1. The surface of the inner limiting ring 11 is slidably connected to the rotating seat 2. The outer limiting ring 10 and the inner limiting ring 11 restrict the position of the rotating seat 2, making it difficult for the transmission tooth groove 9 on the rotating seat 2 to disengage from the gear 8. The rotating seat 2 is more stable when rotating. A notch is provided on the inner limiting ring 11. The surface of the transmission box 6 is fixedly connected to the notch of the inner limiting ring 11.

[0027] In this embodiment, as Figure 1 and Figure 4 As shown, a material discharge groove 12 is provided on the upper surface of the heating table 1. The size of the material discharge groove 12 is larger than that of the discharge hole 5. The position of the material discharge groove 12 is adapted to the limiting frame 4. When the raw material that has been pressed into tablets is moved to the material discharge groove 12 by the rotating seat 2, the raw material that has been pressed into tablets falls from the material discharge groove 12, which facilitates unloading.

[0028] In this embodiment, as Figure 1 and Figure 5 As shown, a mounting groove 17 is provided at the center of the heating table 1. A connecting frame 13 is fixedly connected to the inner wall of the mounting groove 17. A hydraulic rod 14 is fixedly connected to the surface of the connecting frame 13. A pressure plate 15 is fixedly connected to the output end of the hydraulic rod 14. The lower part of the pressure plate 15 is the pressure application position. When the raw material is in the pressure application position, the hydraulic rod 14 is activated, and the hydraulic rod 14 drives the pressure plate 15 to move down, so that the pressure plate 15 and the raw material are mutually pressurized.

[0029] In this embodiment, as Figures 1-5 As shown in this embodiment, the working principle of a lithium battery production pressing device is as follows:

[0030] Step 1: Turn on heating platform 1 to preheat;

[0031] Step 2: Place the raw material inside the limiting frame 4. It should be noted that the material placement position is staggered from the pressurization position. When pressurizing the raw material, the staff should stay away from the pressure plate 15 to improve the safety of the device.

[0032] Step 3: The drive motor 7 drives the gear 8 to rotate. The gear 8 and the transmission tooth groove 9 transmit power, thereby driving the rotating seat 2 to rotate. The raw material moves first under the restriction of the limiting frame 4 and the discharge hole 5, and then moves the raw material to the pressurization position.

[0033] Step 4: The hydraulic rod 14 drives the pressure plate 15 to move downward, and the pressure plate 15 and the raw material are pressurized together.

[0034] Step 5: When the tableted raw material is moved to the discharge trough 12 by the rotating seat 2, the tableted raw material falls from the discharge trough 12 for easy unloading.

[0035] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
