Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery cell hot pressing technology, and in particular to a battery cell hot pressing machine that facilitates material feeding. Background Technology
[0002] After the winding process, the battery cell is in a loose state. Therefore, it needs to be compressed under specific temperature and pressure conditions to make the inside of the cell tightly bonded. After the cell is hot-pressed, the cell and the hot-press plate will stick together under high temperature and pressure. Therefore, a robotic arm is needed to close and clamp the cell, and then move the cell to separate it from the hot-press plate.
[0003] During the process of a robotic arm gripping a battery cell, excessive clamping force can easily deform the cell; conversely, insufficient clamping force will prevent the robotic arm from moving the cell and may even cause it to scratch it due to relative movement. Therefore, before the robotic arm can grip a battery cell, it needs to be repeatedly tested and optimized to minimize damage to the cell during operation, thus reducing the time required for debugging. Utility Model Content
[0004] To facilitate the movement of battery cells by robotic arms, reduce the risk of scratches on the cells, and shorten the debugging time of the robotic arms, this application provides a battery cell hot press that facilitates material unloading.
[0005] The hot pressing machine for battery cells that facilitates material unloading provided in this application adopts the following technical solution:
[0006] A hot pressing machine for easy material unloading of battery cells includes a base and a top seat. The top seat is located above the base. Several lower hydraulic cylinders are fixedly installed on the base. A hot pressing lower plate is commonly installed on the output shaft of the lower hydraulic cylinders. A push-down hole is opened through the hot pressing lower plate. A push-down plate is installed in the push-down hole. A push-down cylinder is installed between the push-down plate and the base. Several upper hydraulic cylinders are fixedly installed on the top seat. A hot pressing upper plate is commonly installed on the output shaft of the upper hydraulic cylinders. An push-up hole is opened through the hot pressing upper plate. An push-up plate is installed in the push-up hole. A push-up cylinder is installed between the push-up plate and the top seat. Heating wires are installed in the hot pressing upper plate, hot pressing lower plate, push-up plate, and push-down plate.
[0007] By adopting the above technical solution, during the hot pressing of the battery cell, the heating wire is energized and heats up. The top of the lower hot pressing plate and the top of the lower push plate are flush. The battery cell is placed on the top of the lower hot pressing plate and the top of the lower push plate. Then, the upper hydraulic cylinder and the upper push cylinder are activated. The upper hydraulic cylinder drives the upper hot pressing plate to descend, and the upper push cylinder drives the upper push plate to descend, so that the upper hot pressing plate and the upper push plate descend synchronously and the bottom of the upper hot pressing plate is flush with the bottom of the upper push plate. This causes the upper hot pressing plate and the lower hot pressing plate to press the battery cell, and the upper push plate and the lower push plate to press the battery cell, thus achieving the effect of hot pressing the battery cell. When the hot pressing of the battery cell is completed, the heating wire is de-energized, the upper push cylinder drives the upper push plate to reset, so that the upper push plate separates from the upper surface of the battery cell. Then, the upper hydraulic cylinder drives the upper hot pressing plate to move upward, and at the same time, the lower hydraulic cylinder drives the upper hot pressing plate to move upward, so that the hot pressing plate... The upper pressure plate and the hot-pressing plate clamp the battery cell and move them upwards synchronously, thereby separating the lower push plate from the lower surface of the battery cell. Then, the upper push cylinder drives the upper push plate to move downwards until it is in contact with the top of the battery cell, while the lower push cylinder drives the lower push plate to move upwards until it is in contact with the bottom of the battery cell. After the battery cell is clamped between the upper and lower push plates, the upper hydraulic cylinder drives the hot-pressing plate to reset, separating the bottom of the hot-pressing plate from the upper surface of the battery cell. The lower hydraulic cylinder drives the hot-pressing plate to reset, separating the top of the hot-pressing plate from the lower surface of the battery cell. At this time, the sides of the battery cell are suspended. After the robot arm is moved to the bottom of the battery cell, the upper and lower push plates reset, allowing the battery cell to be mounted on the robot arm. The robot arm lifts the battery cell and moves it, replacing the method of closing and clamping the battery cell, reducing the possibility of the robot arm scratching the battery cell and shortening the robot arm debugging time.
[0008] Preferably, an anti-stick layer is provided at the bottom of the upper hot press plate, the top of the lower hot press plate, the bottom of the upper push plate, and the top of the lower push plate.
[0009] By adopting the above technical solution, the anti-sticking layer comes into contact with the battery cell during the hot pressing process, making it less likely for the battery cell to stick together.
[0010] Preferably, a frame is fixedly arranged between the top seat and the base, a guide groove is opened on the frame, a guide block is slidably arranged in the guide groove, and the guide block is fixedly connected to the hot press plate.
[0011] By adopting the above technical solution, the guide block moves along the guide groove during the movement of the hot press plate, which improves the stability of the hot press plate movement and makes the hot press plate less prone to tilting.
[0012] Preferably, the top seat has several guide holes, and a guide rod is inserted into the guide holes. The bottom of the guide rod is fixedly connected to the top of the upper push plate.
[0013] By adopting the above technical solution, the guide rod moves along the guide hole during the movement of the upper push plate, which improves the stability of the upper push plate movement and makes the upper push plate less prone to tilting.
[0014] Preferably, a support frame is fixedly installed on the base, and the top of the support frame is used to abut against the bottom of the hot press plate and the bottom of the push plate.
[0015] By adopting the above technical solution, when the battery cell is hot-pressed, the lower hot-pressing plate is mounted on the support frame, and the lower push plate is mounted on the support frame. When the upper hot-pressing plate presses the lower hot-pressing plate, the stability of the lower hot-pressing plate is improved, and the failure of the lower hydraulic cylinder due to excessive pressure is reduced. When the upper push plate presses the lower push plate, the stability of the lower push plate is improved, and the failure of the lower push cylinder due to excessive pressure is reduced.
[0016] Preferably, the bottom of the push plate has a second positioning hole for the output shaft of the push cylinder to be inserted.
[0017] By adopting the above technical solution, when the battery cell is hot-pressed, the lower push plate is mounted on the support frame, and the output shaft of the lower push cylinder does not abut against the inner wall of the second positioning hole. When the upper push plate presses the lower push plate, the stability of the lower push plate is improved, and the situation of the lower push cylinder malfunctioning due to excessive pressure is reduced.
[0018] Preferably, a first push plate is fixedly mounted on the output shaft of the lower hydraulic cylinder. A through hole is opened on the first push plate for the output shaft of the lower push cylinder to move. Several first push rods are fixedly mounted on the top of the first push plate and pass through the support frame. Several first positioning holes are opened at the bottom of the hot-pressing lower plate for the first push rods to be inserted.
[0019] By adopting the above technical solution, when the battery cell is hot-pressed, the lower hot-press plate is mounted on the support frame, and the output shaft of the first push rod does not abut against the inner wall of the first positioning hole. When the upper hot-press plate presses the lower hot-press plate, the stability of the lower hot-press plate is improved, and the situation of failure due to excessive pressure on the lower hydraulic cylinder is reduced.
[0020] Preferably, the inner wall of the second positioning hole is in contact with the side wall of the output shaft of the push cylinder, and the inner wall of the first positioning hole is in contact with the side wall of the first push rod.
[0021] By adopting the above technical solution, the lower push plate is less prone to swaying left and right due to the restriction of the lower push cylinder output shaft, and the hot press lower plate is less prone to swaying due to the restriction of the first push rod, thereby improving the stability of the hot press lower plate and the lower push plate.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. By setting up a base, top seat, lower hydraulic cylinder, hot-pressing lower plate, lower push hole, lower push plate, lower push cylinder, upper hydraulic cylinder, hot-pressing upper plate, upper push hole, upper push cylinder and heating wire, the battery cell is mounted on the robotic arm.

[0033] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.
[0034] This application discloses a hot pressing machine for battery cells that facilitates material unloading. (Refer to...) Figures 1 to 6The system includes a frame 1, with a top seat 12 welded to the top and a base 11 welded to the bottom. The top seat 12 is located above the base 11. Several lower hydraulic cylinders 21 are mounted on the base 11, and a hot-pressing lower plate 2 is mounted on the output shaft of each lower hydraulic cylinder 21. A push-down hole 32 is formed through the hot-pressing lower plate 2, and a push-down plate 3 is installed inside the push-down hole 32, with the side wall of the push-down plate 3 fitting against the inner wall of the push-down hole 32. A push-down cylinder 31 is mounted on the base 11, and its output shaft is connected to the bottom of the push-down plate 3. Several upper hydraulic cylinders 41 are mounted on the top seat 12, and a hot-pressing upper plate 4 is bolted to the output shaft of each upper hydraulic cylinder 41. A push-up hole 52 is formed through the hot-pressing upper plate 4, and a push-up plate 5 is installed inside the push-up hole 52, with its outer wall fitting against the inner wall of the push-up hole 52. An push-up cylinder 51 is mounted on the top seat 12, and its output shaft is connected to the top of the push-up plate 5. Heating wires 6 are arranged inside the upper hot-pressing plate 4, the lower hot-pressing plate 2, the upper push plate 5, and the lower push plate 3. When the battery cell 7 is hot-pressed, the heating wires 6 are energized and generate heat. After the battery cell 7 is hot-pressed, the heating wires 6 are de-energized. Step 1: Loading the battery cell 7. The output shafts of the upper hydraulic cylinder 41, the upper push cylinder 51, the lower hydraulic cylinder 21, and the lower push cylinder 31 are all fully retracted. At this time, the top of the lower hot-pressing plate 2 and the top of the lower push plate 3 are flush, thus placing the battery cell 7 on the top of the lower hot-pressing plate 2 and the top of the lower push plate 3. Step 2: Hot-pressing the battery cell 7. The upper hydraulic cylinder 41 and the upper push cylinder 51 are activated. The upper hydraulic cylinder 41 drives the upper hot-pressing plate 4 to descend, and the upper push cylinder 51 drives the upper push plate 5 to descend. Step 3: Separate the upper push plate 4 from the battery cell 7. The upper push plate 4 and the upper push plate 5 are lowered synchronously, keeping their bottoms flush. This applies a downward force to the battery cell 7, while the lower push plate 2 and the lower push plate 3 apply an upward force, achieving the effect of hot pressing the battery cell 7. Step 4: Separate the lower push plate 3 from the battery cell 7. The upper push plate 4 and the upper push plate 5 clamp the battery cell 7 and remain stationary. The upper push cylinder 51 drives the upper push plate 5 to reset, causing relative movement between the upper push plate 5 and the battery cell 7, thus separating the upper push plate 5 from the upper surface of the battery cell 7. Step 5: Separate the lower push plate 3 from the battery cell 7. The upper hydraulic cylinder 41 moves the upper push plate 4 upward, and the lower hydraulic cylinder 21 moves the upper push plate 4 upward simultaneously, causing the upper push plate 4 and the battery cell 7 to move upward synchronously. The lower push plate 3 remains stationary, causing relative movement between the lower push plate 3 and the battery cell 7, thus separating the lower push plate 3 from the surface of the battery cell 7. Step 5: The upper push plate 5 and the lower push plate 3 clamp the battery cell 7. The upper push cylinder 51 moves the upper push plate 5 down to fit against the top of the battery cell 7, while the lower push cylinder 31 moves the lower push plate 3 up to fit against the bottom of the battery cell 7, thus confining the battery cell 7 between the upper push plate 5 and the lower push plate 3. Step 6: Separate the hot-pressing upper plate 4 from the battery cell 7; separate the hot-pressing lower plate 2 from the battery cell 7. The upper hydraulic cylinder 41 moves the hot-pressing upper plate 4 back to its original position, and the lower hydraulic cylinder 21 moves the hot-pressing lower plate 2 back to its original position. This separates the bottom of the hot-pressing upper plate 4 from the upper surface of the battery cell 7, and separates the top of the hot-pressing lower plate 2 from the lower surface of the battery cell 7. Step 7: Unload the battery cell 7.At this point, the battery cell 7 is suspended on both sides. After the robotic arm is moved to the bottom of the battery cell 7, the upper push plate 5 and the lower push plate 3 reset, allowing the battery cell 7 to be mounted on the robotic arm. The robotic arm then lifts the battery cell 7 and moves it. This method replaces the previous method of using the robotic arm to close and clamp the battery cell 7, reducing the possibility of the robotic arm scratching the battery cell 7 and shortening the robotic arm's debugging time.
[0035] Reference Figures 1 to 6 The bottom of the upper hot-pressing plate 4, the top of the lower hot-pressing plate 2, the bottom of the upper push plate 5, and the top of the lower push plate 3 are all coated with a ceramic anti-stick layer 61. During the hot-pressing process of the battery cell 7, the anti-stick layer 61 comes into contact with the battery cell 7, making it less likely for the battery cell 7 to stick together.
[0036] To ensure stable movement of the hot press plate 4 and the upper push plate 5, refer to... Figures 1 to 6 A guide groove 42 is formed on the frame 1, and a guide block 43 is slidably disposed within the guide groove 42. The side wall of the guide block 43 is in contact with the inner wall of the guide groove 42, and the guide block 43 is integrally formed with the hot press plate 4. During the movement of the hot press plate 4, the guide block 43 moves along the guide groove 42, improving the stability of the movement of the hot press plate 4 and making it less prone to tilting. Several guide holes 54 are formed on the top seat 12, and guide rods 53 are inserted into the guide holes 54. The outer wall of the guide rod 53 is in contact with the inner wall of the guide hole 54, and the bottom of the guide rod 53 is integrally formed with the top of the upper push plate 5. During the movement of the upper push plate 5, the guide rod 53 moves along the guide hole 54, improving the stability of the movement of the upper push plate 5 and making it less prone to tilting.
[0037] To ensure stable movement of the lower hot press plate 2 and the lower push plate 3, refer to Figures 1 to 6A support frame 8 is welded onto the base 11. The top of the support frame 8 is used to abut against the bottom of the hot-pressing lower plate 2 and the bottom of the lower push plate 3. A second positioning hole 822 is started at the bottom of the lower push plate 3. The second positioning hole 822 is used for the insertion of the output shaft of the lower push cylinder 31. The inner wall of the second positioning hole 822 is in contact with the side wall of the output shaft of the lower push cylinder 31. A first push plate 81 is welded together with the output shaft of the lower hydraulic cylinder 21. A through hole 813 is opened through the first push plate 81, and the through hole 813 is used for the movement of the output shaft of the lower push cylinder 31. Several first push rods 811 are welded to the top of the first push plate 81. The first push rods 811 pass through the support frame 8. Several first positioning holes 812 are started at the bottom of the hot-pressing lower plate 2. The first positioning holes 812 are used for the insertion of the first push rods 811, and the inner wall of the first positioning holes 812 is in contact with the side wall of the first push rods 811. When the battery cell 7 is hot-pressed, the lower hot-press plate 2 is mounted on the support frame 8, and the first push rod 811 does not abut against the inner wall of the first positioning hole 812. When the upper hot-press plate 4 presses against the lower hot-press plate 2, the support seat replaces the lower hydraulic cylinder 21 to provide support for the lower hot-press plate 2, reducing the possibility of the lower hydraulic cylinder 21 malfunctioning due to excessive pressure. When the lower hydraulic cylinder 21 pushes the lower hot-press plate 2 to move, the lower hot-press plate 2 is less prone to shaking due to the restriction of the first push rod 811, thereby improving the stability of the lower hot-press plate 2. When the battery cell 7 is hot-pressed, the lower push plate 3 is mounted on the support frame 8, and the output shaft of the lower push cylinder 31 does not abut against the inner wall of the second positioning hole 822. When the upper push plate 5 presses against the lower push plate 3, the support seat replaces the lower push cylinder 31 to provide support for the lower push plate 3, reducing the possibility of the lower push cylinder 31 malfunctioning due to excessive pressure. When the lower pusher cylinder 31 pushes the lower pusher plate 3 to move, the lower pusher plate 3 is restricted by the output shaft of the lower pusher cylinder 31 and is not prone to swaying left and right, thus improving the stability of the lower pusher plate 3.
[0038] The implementation principle of a hot pressing machine for easy unloading of battery cells 7 according to an embodiment of this application is as follows: Step 1: Loading battery cells 7. The output shafts of the upper hydraulic cylinder 41, the upper push cylinder 51, the lower hydraulic cylinder 21, and the lower push cylinder 31 are all in a fully retracted state. At this time, the top of the lower hot pressing plate 2 and the top of the lower push plate 3 are flush, thus placing the battery cells 7 on the top of the lower hot pressing plate 2 and the top of the lower push plate 3. Step 2: The heating wire 6 is energized, and the battery cells 7 are hot-pressed. The upper hydraulic cylinder 41 and the upper push cylinder 51 are activated. The upper hydraulic cylinder 41 drives the upper hot pressing plate 4 to descend, and the upper push cylinder 51 drives the upper push plate 5 to descend. The bottom of the upper hot pressing plate 4 and the bottom of the upper push plate 5 are kept flush and descend synchronously, so that the upper hot pressing plate 4 and the upper push plate 5 apply a downward force to the battery cells 7, and the lower hot pressing plate 2 and the lower push plate 3 apply an upward force to the battery cells 7, thereby achieving the effect of hot pressing the battery cells 7. Step 3: De-energize heating wire 6, separating the upper push plate 5 from the battery cell 7. The hot-pressing upper plate 4 clamps the battery cell 7 and remains stationary. The upper push cylinder 51 drives the upper push plate 5 to reset, causing relative movement between the upper push plate 5 and the battery cell 7, thereby separating the upper push plate 5 from the upper surface of the battery cell 7. Step 4: De-energize heating wire 6, separating the lower push plate 3 from the battery cell 7. The upper hydraulic cylinder 41 drives the hot-pressing upper plate 4 upward, while the lower hydraulic cylinder 21 simultaneously drives the hot-pressing upper plate 4 upward, causing the hot-pressing upper plate 4 and the battery cell 7 clamped by the hot-pressing upper plate 4 to move upward synchronously. The lower push plate 3 remains stationary, causing relative movement between the lower push plate 3 and the battery cell 7, thereby separating the lower push plate 3 from the surface of the battery cell 7. Step 5: De-energize heating wire 6, and the upper push plate 5 and the lower push plate 3 clamp the battery cell 7. The upward-pushing cylinder 51 moves the upward-pushing plate 5 downward to fit against the top of the battery cell 7, while the downward-pushing cylinder 31 moves the downward-pushing plate 3 upward to fit against the bottom of the battery cell 7, thus confining the battery cell 7 between the upward-pushing plate 5 and the downward-pushing plate 3. Step Six: The heating wire 6 is de-energized, separating the upper hot-pressing plate 4 from the battery cell 7; separating the lower hot-pressing plate 2 from the battery cell 7. The upper hydraulic cylinder 41 resets the upper hot-pressing plate 4, and the lower hydraulic cylinder 21 resets the lower hot-pressing plate 2. This separates the bottom of the upper hot-pressing plate 4 from the upper surface of the battery cell 7, and the top of the lower hot-pressing plate 2 from the lower surface of the battery cell 7. Step Seven: The heating wire 6 is de-energized, and the battery cell 7 is unloaded. At this time, the sides of the battery cell 7 are suspended. After the robotic arm is moved to the bottom of the battery cell 7, the upper push plate 5 and the lower push plate 3 reset, allowing the battery cell 7 to be mounted on the robotic arm, which then lifts and moves the battery cell 7. Instead of using a robotic arm to close and clamp the battery cell 7, this method reduces the chance of the robotic arm scratching the battery cell 7 and shortens the robotic arm's debugging time.
[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
