Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, and in particular to a pressure formation device. Background Technology

[0002] During battery manufacturing, charging and discharging are used to activate the active materials within the battery and to produce a solid electrolyte interphase (SEI) film on the electrode surface. This process is called battery formation. Gases are generated during battery formation, and these gases can affect the quality of the formed film, which in turn affects the battery's performance and safety.

[0003] Currently, the general process for battery formation involves first clamping each battery individually into a restraint tray, then placing the restraint tray into a pressure formation apparatus, which applies pressure to the batteries. The restraint trays are heavy and bulky, and the pressure formation apparatus incorporates numerous load-bearing structures to ensure uniform and stable pressure application. This makes it difficult to move the restraint trays into and out of the apparatus, resulting in significant handling challenges and reduced formation efficiency.

[0004] Therefore, there is an urgent need for a pressure formation device to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a pressure formation device that is easy to use and has high formation efficiency.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] Pressure formation equipment, including:

[0008] A pressurizing device, wherein the pressurizing device is configured with a first station and a second station;

[0009] A pallet device, which is adjustablely positioned between the first workstation and the second workstation;

[0010] A mobile device extends from the first workstation and the second workstation and is tractively connected to the pallet device.

[0011] The beneficial effects of this pressure formation equipment are as follows: Since the fixing and separation of the restraint tray occurs at a second station, it is not affected by the complex structure of the pressurizing device. Various tooling can be used to achieve labor-saving transportation of the restraint tray, thus greatly reducing the difficulty of handling. During operation, there is no need to fix the restraint tray multiple times; only fixing and separation between the restraint tray and the tray device are required, ensuring formation efficiency. Simultaneously, since both fixing and separation occur at the second station, the risk of collision and damage between the restraint tray and the pressurizing device during handling is avoided, improving safety during the formation process.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0031] The following is based on the appendix Figure 1 To be continued Figure 8 This invention introduces the pressure formation equipment provided by this utility model.

[0032] like Figure 1 , Figure 2 As shown, in this embodiment, the pressure formation equipment mainly includes a pressurizing device 2, a tray device 3, and a moving device 4. The pressurizing device 2 is configured with a first station 100 and a second station 200, and includes a pressurizing drive 21. When the restraint tray 5 carrying the battery is located in the first station 100, the pressurizing drive 21 can apply pressure to the battery on the restraint tray 5, thereby promoting gas discharge during the formation process. The second station 200 is located laterally to the first station 100, and relative to the first station 100, the second station 200 has convenient handling conditions for placing and removing the restraint tray 5. The tray device 3 is adjustablely positioned between the first station 100 and the second station 200. The tray device 3 includes a mounting assembly that can limit the installation of the restraint tray 5, thereby fixing the restraint tray 5 and the tray device 3 relatively. The moving device 4 is set at the first station 100 and the second station 200 and is connected to the pallet device 3 by transmission. It can facilitate the movement of the pallet device 3 between the first station 100 and the second station 200, or drive the pallet device 3 to move between the first station 100 and the second station 200.

[0033] When using, refer to Figure 2 , Figure 3 As shown, the tray device 3 is first moved to the second station 200, providing convenient handling conditions for placing the restraint tray 5 and preventing interference from structures such as the pressurizing device 2 on the installation of the restraint tray 5. Then, the restraint tray 5 carrying the battery is placed on the tray device 3, and the restraint tray 5 and the tray device 3 are fixed relative to each other using the mounting components. Next, using the moving device 4, the tray device 3 and the pressurizing device 2 are moved together to the first station 100 to complete the preparatory work before pressurization. The battery can then be pressurized and formed using the pressurizing device 2.

[0034] After formation is complete, the pressure on the battery is first released by the pressurizing drive 21, allowing the tray device 3 to move. Then, the moving device 4 is used to move the tray device 3 to the second station 200. At this point, the operator can easily remove the restraint tray 5, avoiding the difficulty in removing the restraint tray 5 due to interference from the pressurizing device 2 and other structures. Understandably, since the second station 200 is not affected by the complex structure of the pressurizing device 2, the operator can use various tooling to achieve labor-saving transportation of the restraint tray 5, thus greatly reducing the difficulty of handling. During operation, there is no need to repeatedly fix the restraint tray 5; only fixing and separating it from the tray device 3 is required, ensuring formation efficiency. Both fixing and separating occur at the second station 200, avoiding the risk of collision and damage between the restraint tray 5 and the pressurizing device 2 during handling, thus improving safety during the formation process.

[0035] Specifically, such as Figure 1 , Figure 2 As shown, the pressure formation equipment also includes a mounting base plate 1, and the pressurizing device 2 includes a pressurizing frame 22. Both the pressurizing frame 22 and the pressurizing drive unit 21 are fixedly mounted on the mounting base plate 1. The first station 100 is located inside the pressurizing frame 22, and the second station 200 is located outside the pressurizing frame 22, allowing the second station 200 to be unaffected by the pressurizing frame 22, thus providing better handling conditions compared to the first station 100. The aforementioned tray inlet / outlet is defined between the pressurizing frame 22 and the mounting base plate 1, and the tray inlet / outlet is arranged along a horizontal first direction (as shown by the X-axis in the figure). The tray device 3 can move between the first station 100 and the second station 200 via the tray inlet / outlet. When the tray device 3 is at the second station 200, it can avoid interference from structures such as the pressurizing frame 22, providing convenient handling conditions for placing and removing the tray 5. When the tray device 3 carries the restraint tray 5 into the pressurizing device 2, the pressurizing drive 21 can apply pressure to the battery in the restraint tray 5 along the second horizontal direction (as shown by the Y-axis in the figure), which is perpendicular to the first horizontal direction.

[0036] Of course, in some embodiments, the pressure frame 22 can be designed to avoid obstacles, thereby forming the aforementioned second workstation 200 on the inner side of the pressure frame 22 or at other locations, and providing convenient handling conditions for placing and removing the restraint tray 5 at the second workstation 200. Therefore, the specific location of the second workstation 200 and the specific shape of the pressure frame 22 are not limited in this utility model, as long as they facilitate the placement and removal of the restraint tray 5.

[0037] like Figures 2 to 4 As shown, in this embodiment, the moving device 4 includes a guide rail 41, a first slider, and a first driving member 42. The guide rail 41 is fixedly mounted on the mounting base plate 1 along a horizontal first direction, with one end extending to a first station 100 and the other end extending to a second station 200. The first slider is slidably mounted on the guide rail 41 and fixedly connected to the bottom of the tray device 3, thereby slidably mounting the tray device 3 on the mounting base plate 1, allowing the tray device 3 to move along the guide rail 41 between the first station 100 and the second station 200. The first driving member 42 is a motor, driven and connected to the tray device 3, providing power for the movement of the tray device 3 and precisely controlling the position of the tray device 3, thereby carrying the restraint tray 5 between the first station 100 and the second station 200.

[0038] Specifically, in this embodiment, the moving device 4 further includes a lead screw 43 and a second slider. A first driving member 42 is connected to the lead screw 43 via a coupling 44, and the axis of the lead screw 43 is arranged along a horizontal first direction. A lead screw nut is threaded onto the lead screw 43, and the lead screw nut and the second slider are fixedly connected, with the second slider also fixedly connected to the bottom of the tray device 3. When the first driving member 42 drives the lead screw 43 to rotate, the tray device 3 can move along the horizontal first direction. By driving the lead screw 43 to rotate in different directions, the tray device 3 can move towards the first workstation 100 or towards the second workstation 200.

[0039] Preferably, the moving device 4 includes two guide rails 41 arranged in parallel. Each guide rail 41 is provided with at least two first sliders. The multiple first sliders simultaneously support different positions of the pallet device 3, thereby enabling the pallet device 3 to be stably and evenly supported by the multiple first sliders. A lead screw 43 is disposed between the two guide rails 41, and the two guide rails 41 are symmetrically arranged about the lead screw 43, so that under the action of the first driving member 42, the pallet device 3 can move smoothly along the guide rails 41, reducing the phenomenon of jamming or jamming.

[0040] Optionally, in some embodiments, a combination of drive belt and pulley, drive chain and sprocket, etc., can be used to transmit power. Therefore, the present invention does not limit how the first drive member 42 drives the pallet device 3. As long as it can provide power for the movement of the pallet device 3, it falls within the scope of protection of the present invention.

[0041] like Figure 4 , Figure 5 As shown, in this embodiment, the moving device 4 further includes a first limiting component and a second limiting component. The first limiting component, the first station 100, the second station 200, and the second limiting component are arranged sequentially along a horizontal first direction. The first limiting component includes at least one first abutment 45, which is disposed at the edge of the first station 100 away from the second station 200. When the tray device 3 moves from the second station 200 to the first station 100, the first abutment 45 abuts against the tray device 3, preventing further movement of the tray device 3. This allows the tray device 3 to accurately remain stationary within the first station 100, thereby ensuring that pressure is stably and accurately applied to the battery within the restraint tray 5 during formation. Figure 4 As shown, in this embodiment, the first limiting component includes two first abutting members 45, which are fixedly installed on the mounting base plate 1. Optionally, the side of the first abutting member 45 facing the tray device 3 is also provided with an abutting buffer layer, which can be made of materials such as rubber or wood pads, and can play a buffering and protective role.

[0042] Similar to the first limiting component, the second limiting component also includes at least one second abutment 46, which is disposed at the edge of the second station 200 away from the first station 100. When the pallet device 3 moves from the first station 100 to the second station 200, the second abutment 46 abuts against the pallet device 3, thus preventing the pallet device 3 from moving further. This allows the pallet device 3 to remain accurately stationary within the second station 200, ensuring that the pallet device 3 is in a fixed and identical position relative to the mounting base plate 1 each time the restraint pallet 5 is handled, thereby facilitating the insertion and removal of the restraint pallet 5. Figure 5 As shown, the second limiting component includes two second abutment members 46, which are fixedly installed on the mounting base plate 1. The side of the second abutment member 46 facing the tray device 3 is also provided with an abutment buffer layer to avoid collision between the tray device 3 and the second abutment member 46 and cause damage.

[0043] like Figure 6 , Figure 7 As shown, the pallet device 3 includes a pallet frame 31 and mounting components. The pallet frame 31 is made of square steel or similar materials, possessing good load-bearing capacity and capable of stably supporting heavy restraint pallets 5. The mounting components include a first blocking member 32, a clamping member 33, and a second driving member 34. The first blocking member 32 and the second driving member 34 are fixedly mounted to the pallet frame 31. The clamping member 33 is throttledly connected to the second driving member 34 and can approach or move away from the first blocking member 32 under the action of the second driving member 34, thereby making the distance between the clamping member 33 and the first blocking member 32 adjustable. Optionally, in this embodiment, the second driving member 34 is a cylinder.

[0044] Before placing the restraint tray 5 onto the tray device 3, the second drive member 34 moves the clamping member 33 away from the first blocking member 32 until the distance between the first blocking member 32 and the clamping member 33 is sufficient for the insertion of the restraint tray 5. Then, the restraint tray 5 is placed between the first blocking member 32 and the clamping member 33, with one side of the restraint tray 5 abutting against the first blocking member 32. Next, the second drive member 34 moves the clamping member 33 in a direction close to the first blocking member 32 until the clamping member 33 abuts against the restraint tray 5. At this point, the restraint tray 5 is clamped and fixed by the first blocking member 32 and the clamping member 33, thereby ensuring that the restraint tray 5 and the tray device 3 remain relatively fixed during the movement of the tray device 3.

[0045] Preferably, the tray device 3 further includes a plurality of omnidirectional balls 35, which are rotatably mounted on the tray frame 31 and can support the restraint tray 5 from bottom to top, thereby reducing the resistance when the restraint tray 5 is adjusted in position on the tray device 3. After the omnidirectional balls 35 are provided, the restraint tray 5 can be easily pushed toward the first blocking member 32 by the second driving member 34 and the clamping member 33 until the restraint tray 5 is clamped between the first blocking member 32 and the clamping member 33.

[0046] For example, such as Figure 6 , Figure 7 As shown, the tray frame 31 is provided with a plurality of omnidirectional balls 35, which are arranged in an array to evenly support the restraint tray 5 and reduce the movement resistance of the restraint tray 5 relative to the tray frame 31. Along the first horizontal direction, one edge of the tray frame 31 is provided with the aforementioned first blocking member 32, and the other edge is provided with the aforementioned second driving member 34 and clamping member 33. Preferably, the tray frame 31 is provided with two second driving members 34 and two corresponding clamping members 33, which are spaced apart along the second horizontal direction to avoid the restraint tray 5 from tilting or rotating when pushed.

[0047] Furthermore, such as Figure 6 , Figure 7 As shown, a third limiting component is also provided at the edge where the second driving member 34 is located. The third limiting component includes at least one third abutment 36, which is fixedly installed on the tray frame and located on the same side as the clamping member 33 and the first blocking member 32. The third abutment 36 is positioned closer to the first blocking member 32 than the second driving member 34, and can prevent the restraint tray 5 from impacting the second driving member 34 when the second driving member 34 fails, especially during the movement of the tray device 3 from the first station 100 to the second station 200. Optionally, in this embodiment, both the first blocking member 32 and the third abutment 36 are plate-shaped and their length direction is arranged along the second horizontal direction, thereby providing a good blocking effect on the restraint tray 5. Furthermore, both the first blocking member 32 and the third abutment 36 have abutment buffer layer on the side facing the restraint tray 5 to avoid collision damage.

[0048] Preferably, in this embodiment, the pallet device 3 further includes a fourth limiting component, which includes at least one fourth abutment member 37, and the fourth abutment member 37 is fixedly disposed at one end of the pallet device 3 along the second horizontal direction. Figure 6 , Figure 7As shown, along the second horizontal direction, one end of the pallet device 3 is provided with three fourth abutment members 37. The fourth abutment members 37, the pallet frame 31, the first blocking member 32, and the third abutment members 36 define a receiving space. An operator can place the restraint pallet 5 into the receiving space from the other end of the pallet device 3 along the second horizontal direction and push the restraint pallet 5 until it abuts against the fourth abutment members 37, thereby achieving the positioning of the restraint pallet 5 along the second horizontal direction. Similarly, the side of the fourth abutment member 37 facing the restraint pallet 5 is also provided with an abutment buffer layer to prevent collision damage.

[0049] Optionally, such as Figure 6 As shown, the end plates of the first blocking member 32 and the third abutting member 36, which are far from the fourth abutting member 37, are also provided with guide arc surfaces. The guide arc surfaces can guide the restraint tray 5 when it enters the receiving space, thereby facilitating the operator to transport the restraint tray 5.

[0050] like Figure 8 As shown, the tray device 3 also includes a fifth limiting component, which includes at least one fifth abutment 38. Along the second horizontal direction, the fifth abutment 38 and the fourth abutment 37 are spaced apart, and the fifth abutment 38 is movably positioned along the vertical direction (as shown by the Z-axis in the figure). The fifth abutment 38 has a first state protruding from the tray frame 31 and a second state not higher than the tray frame 31. In this embodiment, the fifth limiting component includes multiple fifth abutments 38 and multiple lifting drive components 39. The lifting drive components 39 can be cylinders or motors, capable of driving the fifth abutments 38 to rise and fall, thereby switching the fifth abutment 38 between the first and second states. During the process of the operator placing the restraint tray 5 into the receiving space, the fifth abutments 38 are always in the second state to avoid obstructing the movement of the restraint tray 5. When the restraint tray 5 simultaneously abuts against the first blocking member 32, the clamping member 33, and the fourth abutment 37 within the receiving space, the fifth abutments 38 will rise until they are in the first state. At this time, along the second horizontal direction, the fifth abutment 38 and the fourth abutment 37 will limit and fix the restraint tray 5, thereby achieving the effect of clamping and fixing the restraint tray 5.

[0051] Preferably, the fifth limiting component further includes a sensor capable of detecting the state of the fifth abutment 38 by detecting the movement distance or the position. For example, when the restraint tray 5 is within the receiving space and not abutting the fourth abutment 37, the fifth abutment 38 cannot be transformed to the first state under the drive of the lifting drive 39. The sensor can detect an abnormal state of the fifth abutment 38, thereby reflecting an abnormal position of the restraint tray 5.
