Description

Technical Field

[0001] This application relates to the field of fixture technology, and in particular to a reflux fixture based on vacuum adsorption and a reflux conveyor line. Background Technology

[0002] In existing battery cell production, after the battery cell is assembled, the side sealing edges need to be folded. The current production method is to place the assembled battery cell on a reflow fixture, and then use a magnetic levitation reflow line to transport the reflow fixture and battery cell to various stations of the folding device. The current reflow fixture is generally divided into an upper clamping plate and a lower clamping plate, and each reflow fixture is equipped with a clamping drive. The clamping drive is used to control the upper and lower clamping plates to clamp or release the battery cell, thereby ensuring the fixation of the battery cell. However, the clamping drive needs to be placed above the upper clamping plate, which increases the overall space occupied by the battery cell reflow fixture and increases the structural complexity of the battery cell reflow fixture. Utility Model Content

[0003] To address one of the aforementioned technical problems, this application provides a vacuum adsorption-based reflux fixture, comprising a fixed frame, a clamping assembly, and an adsorption structure. The adsorption structure is fixedly mounted on the fixed frame and used to adsorb material. The clamping assembly is slidably connected to the fixed frame, and moves closer to or further away from the adsorption structure to press down or release the material on the adsorption structure. This allows the clamping assembly to press down on the battery cell material on the adsorption structure, ensuring the battery cell is fixed without the need for an additional driver to push the clamping assembly down and fix the battery cell. This simplifies the structure of the battery cell fixture and saves space.

[0004] Preferably, the clamping assembly includes a lifting frame and a pressure plate. The lifting frame is slidably mounted on the fixed frame, and the pressure plate is located at the end of the lifting frame facing the adsorption structure. The battery cell is adsorbed by the adsorption structure, and simultaneously, the lifting frame and pressure plate move closer to the adsorption structure under their own weight, causing the pressure plate to press down on the upper surface of the battery cell, further fixing the battery cell to the adsorption structure.

[0005] Preferably, the clamping assembly includes an abutment post, which is disposed at the end of the lifting frame away from the adsorption structure. Furthermore, an opening clamping mechanism can be provided at the cell loading and unloading stations on the return conveyor line. This mechanism clamps the abutment post, thereby pulling up the lifting frame and moving the pressure plate away from the cells on the adsorption structure. This achieves cell loading and unloading without requiring a driver on each return fixture to operate the clamping assembly, thus simplifying the structure of the cell fixture.

[0006] Preferably, a sliding groove is formed within the fixed frame, and a bushing is fitted into the sliding groove. The lifting frame is provided with a guide post that slides into the bushing. Thus, through the sliding engagement between the guide post and the bushing, the lifting frame can move smoothly up and down.

[0007] Preferably, an elastic element is sleeved around the outer periphery of the guide post, one end of which abuts against the bushing, and the other end of which is connected to the end of the guide post. When the clamping assembly descends toward the adsorption structure under its own weight, the elastic element cushions the descent of the clamping assembly, thereby preventing the lifting frame and pressure plate from directly crushing the battery cell and improving safety.

[0008] Preferably, the adsorption structure is an adsorption plate, the adsorption plate has an internal air extraction channel, the bearing surface of the adsorption plate has adsorption holes communicating with the air extraction channel, and the fixing frame has an air extraction port communicating with the air extraction channel. This air extraction creates a negative pressure within the air extraction channel, thereby causing the adsorption holes to adsorb and fix the battery cell.

[0009] Preferably, the return clamp further includes a vacuum assembly connected to the vacuum port. This creates a vacuum in the vacuum channel, allowing the suction port to hold and fix the battery cell. In some embodiments, the vacuum assembly can be connected to the vacuum port via a pipe connector.

[0010] Preferably, the return fixture further includes a movable frame, on which the fixed frame is mounted, and the movable frame is provided with a plurality of sliders. The movable frame and the fixed frame are moved by the return line, thereby conveying the battery cells to various stations of the bending device for bending. Furthermore, the aforementioned air extraction assembly can also be mounted on the movable frame, thereby connecting the air extraction assembly with the air extraction port on the fixed frame.

[0011] Preferably, a return conveyor line includes the aforementioned vacuum-adsorption-based return fixture and a magnetically levitated return line, wherein the magnetically levitated return line drives the return fixture to move. A slider on the moving frame is slidably connected to a slide rail on the magnetically levitated return line, thereby driving the return fixture to move via the magnetically levitated return line, enabling the battery cells to be conveyed to various stations of the folding device.

[0012] Preferably, the recirculation conveyor line further includes an opening clamping mechanism disposed on the moving path of the recirculation fixture. The opening clamping mechanism is used to drive the clamping assembly away from the adsorption structure. When the recirculation conveyor line drives the recirculation fixture to the cell loading or unloading station, the opening clamping mechanism clamps the abutment column on the lifting frame, thereby pulling the lifting frame up and causing the pressure plate to move away from the cell on the adsorption structure. This achieves cell loading or unloading without the need to set a driver on each recirculation fixture to drive the clamping assembly, thus simplifying the structure of the cell fixture.

[0013] Compared with the prior art, the beneficial effects of this application are as follows: This application sets an adsorption structure for adsorbing materials on a fixed frame, and a pressing component is slidably connected to the fixed frame. The pressing component moves closer to or away from the adsorption structure, thereby forming a space for accommodating the battery cell material between the adsorption structure and the pressing component. After the battery cell material is placed on the adsorption structure, the pressing component adsorbs and fixes the battery cell. The pressing component moves closer to the adsorption structure under its own weight, thereby pressing down on the battery cell material on the adsorption structure. Thus, while ensuring that the battery cell is fixed, there is no need to add an additional driver to drive the pressing component to press down and fix the battery cell, thereby simplifying the structure of the battery cell clamp and achieving the purpose of saving the space occupied by the return clamp.

They are merely used to distinguish components or operations described using the same technical terms and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.

[0026] To further understand the content, features, and effects of this application, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0027] To address the aforementioned technical problems, this embodiment provides a reflux fixture based on vacuum adsorption, such as... Figure 1 As shown, the device includes a fixed frame 10, a pressing component 20, and an adsorption structure 30. The adsorption structure 30 is fixedly mounted on the fixed frame 10 and is used to adsorb materials. The pressing component 20 is slidably connected to the fixed frame 10. The pressing component 20 moves closer to or away from the adsorption structure 30, thereby creating a space for accommodating the battery cell material between the adsorption structure 30 and the pressing component 20. After the battery cell material is placed on the adsorption structure 30, the pressing component 20 adsorbs and fixes the battery cell. The pressing component 20 moves closer to the adsorption structure 30 under its own weight, thereby pressing down on the battery cell material on the adsorption structure 30. This ensures that the battery cell is fixed without the need for an additional driver to drive the pressing component 20 to press down and fix the battery cell, thus simplifying the structure of the battery cell clamp and saving space occupied by the return clamp.

[0028] Specifically, such as Figure 2As shown, the clamping assembly 20 includes a lifting frame 21 and a pressure plate 22. The lifting frame 21 is slidably mounted on the fixed frame 10, and the pressure plate 22 is located at the end of the lifting frame 21 facing the adsorption structure 30. After the battery cell material is placed on the adsorption structure 30, the adsorption structure 30 adsorbs the battery cell. Simultaneously, the lifting frame 21 and the pressure plate 22 move closer to the adsorption structure 30 under their own weight, causing the pressure plate 22 to press down on the upper surface of the battery cell, further fixing the battery cell to the adsorption structure 30.

[0029] In the above scheme, the clamping assembly 20 also includes an abutment post 23. The abutment post 23 is located at the end of the lifting frame 21 away from the adsorption structure 30. Then, an opening clamping mechanism can be set at the battery cell loading and unloading station on the return conveyor line. The opening clamping mechanism clamps the abutment post 23, thereby pulling up the lifting frame 21 and making the pressure plate 22 away from the battery cell on the adsorption structure 30. This realizes the loading and unloading of battery cells. It is not necessary to set a driver on each return fixture to drive the clamping assembly 20, thus simplifying the structure of the battery cell fixture.

[0030] Furthermore, in order to improve the stability of the lifting frame 21 in lifting and moving, a sliding groove is provided in the fixed frame 10, and a bushing 42 is installed in the sliding groove. The lifting frame 21 is provided with a guide post 41 that slides and engages with the bushing 42. Thus, through the sliding engagement between the guide post 41 and the bushing 42, the lifting frame 21 can move up and down smoothly.

[0031] In the above scheme, an elastic element 43 is also sleeved on the outer periphery of the guide post 41. One end of the elastic element 43 abuts against the bushing 42, and the other end of the elastic element 43 is connected to the end of the guide post 41. When the pressing assembly 20 moves downward toward the adsorption structure 30 under its own weight, the elastic element 43 plays a buffering role in the fall of the pressing assembly, thereby preventing the lifting frame 21 and the pressure plate 22 from falling directly and damaging the battery cell, thus improving safety.

[0032] Furthermore, in order to achieve the carrying and fixing of battery cells, for example, such as Figure 3-4 As shown, the adsorption structure 30 is an adsorption plate with an air extraction channel inside. Adsorption holes 31, connected to the air extraction channel, are formed on the bearing surface of the adsorption plate. An air extraction port 32, connected to the air extraction channel, is formed on the fixing frame 10. By extracting air, a negative pressure is created within the air extraction channel, causing the adsorption holes 31 to adsorb and fix the battery cell.

[0033] In the above scheme, the return fixture of this embodiment also includes a vacuum assembly, which can be a vacuum device. The vacuum assembly is connected to the vacuum port 32, and the vacuum port 32 is connected to the adsorption hole 31 through a vacuum channel. The vacuum assembly creates a vacuum negative pressure in the vacuum channel, thereby allowing the adsorption hole 31 to adsorb and fix the battery cell. In some embodiments, the vacuum assembly can be connected to the vacuum port 32 through a pipe connector.

[0034] Furthermore, such as Figure 5 As shown, the reflow fixture also includes a movable frame 50, with a fixed frame 10 mounted on the movable frame 50. The movable frame 50 is equipped with several sliders 51, which are slidably connected to the slide rails on the reflow line via the sliders 51. The reflow line drives the movable frame 50 and the fixed frame 10 to move, thereby transporting the battery cells to various stations of the bending device for bending. Furthermore, the aforementioned air extraction assembly can also be mounted on the movable frame 50, and the air extraction assembly is connected to the air extraction port 32 on the fixed frame 10.

[0035] On the other hand, this embodiment also provides a return conveyor line, such as Figure 6 As shown, the device includes the aforementioned return fixture and the magnetic levitation return line 60. The slider 51 on the moving frame 50 is slidably connected to the slide rail on the magnetic levitation return line 60, thereby driving the return fixture to move through the magnetic levitation return line 60, so that the battery cells can be transported to each station of the folding device.

[0036] In the above solution, the recirculation conveyor line of this embodiment also includes an opening clamping mechanism disposed on the moving path of the recirculation fixture. The opening clamping mechanism can be composed of a cylinder and a clamping structure. The opening clamping mechanism is used to drive the pressing assembly 20 away from the adsorption structure 30. For example, the opening clamping mechanism is disposed at the battery cell loading and unloading station. When the recirculation conveyor line drives the recirculation fixture to the battery cell loading or unloading station, the opening clamping mechanism clamps the abutment post 23 on the lifting frame 21, thereby pulling up the lifting frame 21 and causing the pressure plate 22 to move away from the battery cell on the adsorption structure 30, thereby realizing the loading or unloading of the battery cell. It is not necessary to set a driver on each recirculation fixture to drive the pressing assembly 20, thereby simplifying the structure of the battery cell fixture.

[0037] In summary, in one or more embodiments of this application, an adsorption structure for adsorbing materials is provided on a fixed frame, and a pressing component is slidably connected to the fixed frame. The pressing component moves closer to or away from the adsorption structure, thereby forming a space for accommodating the battery cell material between the adsorption structure and the pressing component. After the battery cell material is placed on the adsorption structure, the pressing component adsorbs and fixes the battery cell. The pressing component moves closer to the adsorption structure under its own weight, thereby pressing down on the battery cell material on the adsorption structure. Thus, while ensuring that the battery cell is fixed, there is no need to add an additional driver to drive the pressing component to press down and fix the battery cell, thereby simplifying the structure of the battery cell clamp and saving the space occupied by the return clamp.

[0038] The embodiments described above do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the scope of protection of this technical solution.
