Description

Technical Field

[0001] This application relates to the field of battery cell production, and more particularly to a battery cell hot pressing device and its production equipment. Background Technology

[0002] In the production process of square batteries, after the cells are manufactured, they need to undergo key steps such as adhesive bonding and preheating to ensure a tight bond between the electrodes and the separator and improve the overall performance of the cells. Currently, mainstream hot pressing devices generally adopt a double-layer structure, namely upper and lower hot pressing plates. The upper hot pressing plate uses a precision mechanical transmission system to move up and down and apply pressure.

[0003] However, in practice, the loading of battery cells mostly relies on the direct placement by a robotic arm. Because the space between the upper and lower hot press plates is designed to maximize production efficiency, the robotic arm is very prone to colliding with the hot press plates when placing and removing battery cells. Such collisions may not only damage the battery cells and hot press plates, but may also cause safety accidents. Utility Model Content

[0057] This application provides a battery cell hot pressing device and its production equipment. The battery cell hot pressing device includes a handling module 100, a clamping assembly 200, a transfer module 300, a first hot pressing plate 400, a pressing assembly 500, and a second hot pressing plate 600.

[0058] The clamping assembly 200 is fixedly installed on the moving end of the transport module 100. The clamping assembly 200 is used to clamp the battery cell. The loading position of the transfer module 300 is located on the moving path of the transport module 100. The first hot press plate 400 is located at the moving end of the transfer module 300. The transfer module 300 is used to drive the first hot press plate 400 to move. The pressing assembly 500 is located on the moving path of the first hot press plate 400. The second hot press plate 600 is located at the moving end of the pressing assembly 500.

[0059] See Figure 1As shown, in the initial state, the transfer module 300 moves the first hot press plate 400 to the unloading position of the clamping assembly 200. Then, the transport module 100 moves the clamping assembly 200 to place the battery cell clamped by the clamping assembly 200 onto the first hot press plate 400 at the unloading position. Next, the transfer module 300 transfers the battery cell located on the first hot press plate 400 to directly below the second hot press plate 600. Finally, the pressing assembly 500 moves the second hot press plate... The 600 moves downward to heat-press the battery cell located on the first hot press plate 400. The pressing component 500 drives the second hot press plate 600 upward to complete the heat pressing. Then, the transfer module 300 transfers the battery cell that has been heat-pressed on the first hot press plate 400 to the unloading position of the clamping component 200. The clamping component 200 clamps the heat-pressed battery cell again. Then, the transport module 100 transfers the heat-pressed battery cell clamped by the clamping component 200 to a preset position.

[0060] The conveying module 100 includes a first linear module 110, a second linear module 120 mounted on the moving end of the first linear module 110, a rotary drive 130 mounted on the moving end of the second linear module 120, and a clamping assembly 200 fixedly mounted on the rotary drive 130. The first linear module 110, the second linear module 120 and the rotary drive 130 are linked together to drive the clamping assembly 200 to move in a first preset direction, a second preset direction and a third preset direction.

[0061] See Figure 2 As shown, in this embodiment, the first preset direction is the horizontal or vertical direction on the horizontal plane. In practice, it can be designed and determined to be the horizontal or vertical direction as needed. There is no limitation here. The second preset direction is the height direction, and the third preset direction is the rotation direction.

[0062] Please continue reading. Figure 2 As shown, the clamping assembly 200 is fixedly installed on the rotating end of the rotary drive 130. Through the linkage of the first linear module 110, the second linear module 120 and the rotary drive 130, the clamping assembly 200 can be moved in the horizontal or vertical direction, the height direction and the rotation direction, thereby moving the clamping assembly 200 to a predetermined position.

[0063] In this embodiment, the first linear module 110 and the second linear module 120 are components of a module capable of linear movement. For example, the first linear module 110 and the second linear module 120 can be a motor lead screw linear module, a linear motor module, a synchronous belt linear module, etc., which can be selected according to the actual situation. The specific type is not limited here. The rotary drive component 130 can be a motor. Specifically, in order to accurately control the rotation angle, the rotary drive component 130 can be a servo motor.

[0064] The clamping assembly 200 includes a mounting plate 210. A first sliding plate 220 and a second sliding plate 230 are slidably mounted on the side of the mounting plate 210. A gripper 240 is fixedly mounted on both the first sliding plate 220 and the second sliding plate 230. A clamping drive 250 is fixedly mounted on the mounting plate 210. The clamping drive 250 can drive the first sliding plate 220 and the second sliding plate 230 to move closer to each other or move away from each other.

[0065] See Figure 3 As shown, in order to clamp the battery cell, the first sliding plate 220 and the second sliding plate 230 are slidably mounted on the mounting plate 210 using a guide rail slider. That is, the first sliding plate 220 and the second sliding plate 230 can slide on the mounting plate 210 in a preset direction. Each of the first sliding plate 220 and the second sliding plate 230 has a gripper 240 mounted on the side of the first sliding plate 220 and the second sliding plate 230 that are close to each other. The battery cell located between the two grippers 240 is clamped by the first sliding plate 220 and the second sliding plate 230 moving closer to each other or away from each other. Specifically, the clamping drive 250 has two drive ends. The first sliding plate 220 and the second sliding plate 230 are connected to the drive ends. The clamping drive 250 drives the first sliding plate 220 and the second sliding plate 230 to move closer to each other or away from each other, thereby realizing the clamping or unclamping state of the battery cell.

[0066] In this embodiment, the clamping drive 250 is a cylinder. Specifically, the clamping drive 250 is a double-acting cylinder that can simultaneously drive the first sliding plate 220 and the second sliding plate 230 to move closer to or further apart from each other.

[0067] The mobile end of the transfer module 300 is equipped with a carrier 700, and a first hot press plate 400 is located on the carrier 700. The carrier 700 includes a fixing plate 710, a guide post 720, a carrier plate 730, a load-bearing plate 740, and a first elastic element 750.

[0068] The fixed plate 710 is fixedly installed on the moving end of the transfer module 300. The guide post 720 is slidably installed on the fixed plate 710. The sliding direction of the guide post 720 is perpendicular to the surface of the fixed plate 710. The carrier plate 730 is set on the plane formed by the end of each guide post 720, and the carrier plate 730 is connected to the guide post 720. The first hot press plate 400 is fixedly installed on the carrier plate 730. The bearing plate 740 is located at the ends of two adjacent guide posts 720 on the same side away from the direction of the carrier plate 730. The first elastic element 750 is sleeved on the guide post 720. The guide post 720 is located between the fixed plate 710 and the carrier plate 730.

[0069] When the pressing component 500 drives the second hot pressing plate 600 to press down, if the first hot pressing plate 400 is directly installed on the power output end of the transfer module 300 due to excessive downward pressure, the downward pressure from the pressing component 500 will be completely applied to the transfer module 300, thereby crushing the transfer module 300. Therefore, the first hot pressing plate 400 is installed on the carrier 700, so that the downward pressure is transmitted to the base plate of the mounting bracket 510 through the carrier 700, thereby preventing the transfer module 300 from being crushed.

[0070] See Figure 4 and Figure 5 As shown, the movable end of the transfer module 300 is mounted with a fixing plate 710. Multiple guide posts 720 are slidably mounted on the fixing plate 710 in the height direction. The tops of the multiple guide posts 720 are connected to the same carrier plate 730. A first hot-pressing plate 400 is mounted on the carrier plate 730. A bearing plate 740 is connected at the bottom between the guide posts 720 on the same side. A first elastic element 750 is sleeved on the guide posts 720 and located between the fixing plate 710 and the carrier plate 730. Furthermore, when the battery cell needs to be hot-pressed, the first hot-pressing plate 400 will be pressed and will overcome the elastic force of the first elastic element 750 and move downward. This will also cause the guide posts 720 to slide downward, thereby making the bearing plate 740 contact the bottom plate of the mounting bracket 510. Therefore, the downward pressure will be transmitted to the bottom plate of the mounting bracket 510, so that it can withstand a large downward pressure and will not damage the transfer module 300 while meeting the downward pressure of the battery cell.

[0071] In this embodiment, there are four guide posts 720, which are respectively located at the four corners of the fixing plate 710.

[0072] In this embodiment, the first elastic element 750 is a compression spring.

[0073] In this embodiment, in order to prevent the temperature generated by the first hot press plate 400 from being transferred to other components, the carrier plate 730 can be made of heat-insulating material while meeting the downpressure requirements.

[0074] The carrier plate 730 is provided with a load-bearing telescopic structure 800, which includes a driven frame 810, a guide rod 820, a receiving groove 830, a support bar 840, and a second elastic element 850. The driven frame 810 is located between the fixed plate 710 and the carrier plate 730.

[0075] Multiple guide rods 820 are fixedly mounted on the driven frame 810, and multiple receiving slots 830 are formed on the surface of the first hot press plate 400. The guide rods 820 pass through the carrier plate 730 and the first hot press plate 400 to the inside of the receiving slots 830. Each receiving slot 830 has a support bar 840 fixedly mounted at its end, and the support bar 840 moves with the guide rods 820 and enters or leaves the receiving slot 830. The second elastic member 850 is fixedly mounted on the fixed plate 710, and the other end of the fixed plate 710 abuts against the driven frame 810.

[0076] Since the gripper 240 in the clamping assembly 200 clamps the battery cell in the vertical height direction, in order to prevent the clamped battery cell from colliding with the first hot plate 400 when it is placed on the first hot plate 400, the battery cell needs to be vacated in the initial state so that a clearance space is formed between the battery cell and the first hot plate 400, so that there is enough space to remove the gripper 240.

[0077] Please see Figure 5 , Figure 6 and Figure 7 As shown, multiple guide rods 820 are slidably mounted on the carrier plate 730. A driven frame 810 is mounted on the bottom of the guide rod 820. A sliding hole (not shown) adapted to the guide rod 820 is also provided on the first hot press plate 400. The guide rod 820 can be inserted into the receiving groove 830, and the end of the guide rod 820 away from the driven frame 810 can be located above the first hot press plate 400. A support bar 840 is mounted on the end of the guide rod 820 away from the driven frame 810. The shape of the support bar 840 is adapted to the shape of the receiving groove 830. A second elastic member 850 is installed at the bottom of the driven frame 810. In the initial state, under the elastic force of the second elastic member 850, the support bar 840 is located above the first hot press plate 400 through the transmission of the driven frame 810 and the guide rod 820. At least a space is formed between the first hot press plate 400 and the support bar 840 to accommodate the gripper 240, so as to facilitate the removal of the gripper 240.

[0078] Furthermore, during the handling of the battery cell, the battery cell is first placed on the plane formed by multiple support bars 840. When hot pressing is required, the downward pressure from the second hot pressing plate 600 first overcomes the elastic force of the second elastic element 850, causing the support bars 840 to enter the receiving groove 830. After the support bars 840 are fully inserted into the receiving groove 830, the battery cell contacts the surface of the first hot pressing plate 400. Then, as the downward pressure continues, the downward pressure will be applied to the first hot pressing plate 400, thereby achieving hot pressing.

[0079] In this embodiment, the second elastic element 850 is a compression spring.

[0080] The first hot press plate 400 includes a plate body 410, a mounting hole 420 and an air blowing hole 430. The mounting hole 420 is opened inside the plate body 410, and an electric heating element is installed in the plate body 410. The air blowing hole 430 is opened on the surface of the plate body 410.

[0081] Please see Figure 6 As shown, in order to meet the temperature requirements of hot pressing, mounting holes 420 are made inside the board 410, and heating elements are installed in the mounting holes 420. The heating elements heat up, causing the temperature of the board 410 to rise and meet the hot pressing requirements. After hot pressing is completed, in order to prevent the battery cell from sticking to the surface of the board 410, multiple air blowing holes 430 are made on the board 410. The air blowing holes 430 are connected to external pneumatic equipment, thereby providing air to the air blowing holes 430. That is, after hot pressing is completed, air is blown towards the battery cell through the air blowing holes 430, thereby preventing the battery cell from sticking to the board 410.

[0082] In this embodiment, the second hot press plate 600 has the same structure as the first hot press plate 400, that is, the second hot press plate 600 also has mounting holes 420, heating elements and air blowing holes 430, etc. Furthermore, the heating elements can be heating rods or other heat-generating components.

[0083] The pressing assembly 500 includes a mounting bracket 510, a driven plate 520, a transmission component 530, and a pressing drive component 540.

[0084] The mounting bracket 510 forms an installation space inside, and the driven plate 520 is slidably installed inside the installation space. The second hot press plate 600 is disposed on the side of the driven plate 520 near the transfer module 300. The transmission component 530 is disposed on the side of the driven plate 520 away from the second hot press plate 600. The pressing drive component 540 is fixedly installed on the mounting bracket 510. The driving end of the pressing drive component 540 is connected to the transmission component 530. The pressing drive component 540 is used to drive the driven plate 520 to move through the transmission component 530.

[0085] See Figure 8 As shown, the mounting bracket 510 consists of a base plate, two side plates and a top plate. The two side plates are used to connect the base plate and the top plate. The base plate, the two side plates and the top plate define the mounting space.

[0086] Please continue reading. Figure 8 The pressing drive 540 is mounted on the top plate, the transfer module 300 is mounted on the bottom plate, and the driven plate 520 is mounted on the two side plates via guide rail sliders. Specifically, when pressing down, the pressing drive 540 transmits power to the driven plate 520 through the transmission component 530, thereby driving the second hot press plate 600 on the driven plate 520 to move up and down, so that the second hot press plate 600 moves closer to or away from the first hot press plate 400.

[0087] A heat insulation plate 550 is fixedly installed on the driven plate 520. The heat insulation plate 550 is located between the driven plate 520 and the second hot press plate 600. The second hot press plate 600 is installed with the driven plate 520 through the heat insulation plate 550.

[0088] Please continue reading. Figure 8 In order to prevent heat loss from the second hot plate 600, a heat insulation plate 550 is provided between the driven plate 520 and the second hot plate 600. That is, the heat insulation plate 550 blocks the heat on the second hot plate 600 and prevents the heat from spreading to the driven plate 520.

[0089] For example, the downward driving component 540 can be an electric cylinder, a hydraulic cylinder, or any linear drive component or structure that can meet the downward pressure requirement. In this embodiment, the downward driving component 540 is an electric cylinder.

[0090] A pressure sensor 560 is installed on the drive end of the pressure drive 540.

[0091] Please continue reading. Figure 8 As shown, in order to accurately control the downward pressure acting on the battery cell, a pressure sensor 560 is installed on the drive end of the downward pressure drive 540. The pressure sensor 560 monitors the downward pressure in real time to prevent the battery cell hot pressing process from failing due to insufficient or excessive pressure.

[0092] This application also provides a battery cell manufacturing apparatus, including the battery cell hot pressing device described in any of the above claims.
