Description

Technical Field

[0001] This application relates to the field of battery welding technology, and in particular to an integrated device for tab sheet feeding and welding, and solid-state battery production equipment. Background Technology

[0002] In the existing battery production process, there is a welding process between the battery and the tab sheet. The existing welding method is to transfer the battery to the welding station, and then use a transfer mechanism to load the tab sheet from another loading station to the welding station. The welding station then welds the battery and the tab sheet together. That is, the tab sheet loading and welding are separated into two stations, which results in a large space occupation of the equipment, increased process time, and low production efficiency. Utility Model Content

[0003] To address one of the aforementioned technical problems, this application provides an integrated tab sheet loading and welding device and a solid-state battery production equipment. The device includes a frame, a tab sheet storage assembly disposed on one side of the frame, and a tab sheet transfer assembly and a welding assembly disposed on the frame. A tab sheet transfer assembly is disposed on the frame between the tab sheet storage assembly and the tab sheet transfer assembly. The tab sheet transfer assembly transfers tab sheets from the tab sheet storage assembly to the tab sheet transfer assembly, and the tab sheet transfer assembly transfers tab sheets to the welding assembly. This allows the tab sheet loading operation to be completed simultaneously with the cell's movement to the welding station, ensuring that the cell and tab sheet arrive at the welding station synchronously. The welding assembly then performs ultrasonic welding on the cell and tab sheet, thus achieving an integrated production process for tab sheet loading and welding. This eliminates the need for an additional tab sheet loading station, avoiding the problems of long transportation times and low production efficiency caused by separating tab sheet loading and welding into two separate stations, while also reducing the space occupied by the device.

[0004] Preferably, the tab storage assembly includes a first linear module and a storage rack disposed at the drive end of the first linear module. For example, the second linear module may employ a motor and lead screw structure, and the storage rack forms an accommodating space for placing tabs. Multiple tabs are stacked within the storage rack, and the first linear module moves the storage rack to the tab transfer assembly.

[0005] Preferably, the assembly also includes a transfer station, which is disposed between the tab sheet transfer assembly and the tab sheet conveying assembly. The tab sheet transfer assembly first picks up tab sheets from the storage rack and transfers them to the transfer station, then the tab sheet conveying assembly transfers the tab sheets to the welding assembly, whereby the welding assembly performs ultrasonic welding on the battery cells and electrodes.

[0006] Preferably, the tab sheet transfer assembly includes a mounting frame, a movable plate slidably mounted on the mounting frame, and a second linear module mounted on the mounting frame and connected to the movable plate. At least one set of adsorption components is provided on the movable plate. The movable plate is slidably mounted on the mounting frame via a slide rail. The second linear module drives the movable plate to move, causing the adsorption components to move above the tab sheet storage assembly, thereby adsorbing tab sheets from the storage rack.

[0007] Preferably, the adsorption assembly includes a first driver mounted on the movable plate and an adsorption element disposed at the drive end of the first driver. The first driver is a cylinder, which drives the adsorption element to move up and down, thereby causing the adsorption element to extend into the storage rack to pick up tabs.

[0008] Preferably, the transfer station includes a placement rack and a placement platform disposed on the placement rack, with an adjuster disposed on one side of the placement platform on the placement rack. After the adsorption assembly transfers the tabs from the tab storage assembly to the placement platform, it uses the adjuster to push the tabs on the placement platform for positioning, thereby ensuring that the subsequent adsorption assembly can accurately transfer the tabs to the solid-state battery's soldering area.

[0009] Preferably, the tab transfer assembly includes a third linear module, a mounting base disposed at the moving end of the third linear module, a second driver disposed on the mounting base, and a clamping assembly disposed on the driving end of the second driver. When the tab transfer assembly transfers tabs from the transfer platform to the tab transfer assembly, the clamping assembly clamps the tabs, and then the third linear module drives the mounting base to move, causing the clamping assembly to move the tabs to the solid-state battery welding area of ​​the welding assembly.

[0010] Preferably, the clamping assembly includes a third driver disposed on the driving end of the second driver, and grippers disposed on the driving end of the third driver. The second driver is a bidirectional cylinder, which drives the two grippers to clamp or open towards each other, thereby completing the clamping and releasing action of the tab.

[0011] Preferably, the welding assembly includes a support platform and a welder mounted on the frame, with a pressure plate positioned above the support platform on the frame. After the battery is placed on the support platform, it is fixed in place by the pressure plate. After the tab sheet is loaded onto the battery welding area, the tab sheet and the battery are ultrasonically welded together by the welder.

[0012] Preferably, a solid-state battery production equipment includes the aforementioned integrated tab sheet loading and welding device. This integrated device loads the tab sheets simultaneously with the movement of the battery cells to the welding station, ensuring that the cells and tab sheets arrive at the welding station synchronously. Welding is then performed using welding components, eliminating the need for an additional tab sheet loading station, shortening the process time, and thus improving production efficiency. Furthermore, it also increases the space utilization of the solid-state battery production equipment.

[0013] Compared with the prior art, the beneficial effects of this application are as follows: This application sets a tab sheet storage assembly on one side of the frame, sets a tab sheet transfer assembly and a welding assembly on the frame, and sets a tab sheet transfer assembly on the frame between the tab sheet storage assembly and the tab sheet transfer assembly. After the battery cell is loaded to the welding assembly, the tab sheet on the tab sheet storage assembly is transferred to the tab sheet transfer assembly through the tab sheet transfer assembly, and then the tab sheet is transferred to the battery cell of the welding assembly through the tab sheet transfer assembly. Thus, the tab sheet loading operation is completed at the same time as the battery cell moves to the welding station, so that the battery cell and the tab sheet arrive at the welding station synchronously. Then, the battery cell and the tab sheet are ultrasonically welded by the welding assembly. This realizes the integrated production process of tab sheet loading and welding, without the need to add an additional tab sheet loading station. It avoids the problems of long transportation time and low production efficiency caused by separating tab sheet loading and welding into two separate stations, and at the same time reduces the space occupied by the equipment.

[0023] The following drawings disclose several embodiments of this application. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this application. That is, in some embodiments of this application, these practical details are not essential.

[0024] It should be noted that all directional indications in the embodiments of this application, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

[0025] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit this application. 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. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[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 an integrated device for tab sheet feeding and welding, such as... Figure 1-2 As shown, the assembly includes a frame 10, a tab sheet storage assembly 20 disposed on one side of the frame 10, and a tab sheet transfer assembly 30 and a welding assembly 50 disposed on the frame 10. A tab sheet transfer assembly 40 is disposed on the frame 10 between the tab sheet storage assembly 20 and the tab sheet transfer assembly 30. After the battery cell is loaded onto the welding assembly 50, the tab sheets on the tab sheet storage assembly 20 are transferred to the tab sheet transfer assembly 40 via the tab sheet transfer assembly 30, and then transferred to the welding assembly 50 via the tab sheet transfer assembly 50. Between 0 and 0, the tab sheet is transferred to the battery of the welding assembly 50. Thus, the tab loading operation is completed at the same time as the battery cell moves to the welding station, so that the battery and the tab sheet arrive at the welding station at the same time. Then, the battery cell and the tab sheet are ultrasonically welded by the welding assembly 50. This realizes the integrated production process of tab sheet loading and welding, without the need to add an additional tab sheet loading station. This avoids the problems of long transportation time and low production efficiency caused by separating tab sheet loading and welding into two separate stations, and at the same time reduces the space occupied by the equipment.

[0028] It should be noted that since solid-state battery production requires a confined space, and the integrated tab loading and welding device of this application is suitable for solid-state battery production lines, integrating tab loading and welding into the same station within a limited space can reduce process time, improve production efficiency, and increase space utilization. Furthermore, the ultrasonic welding used in the integrated tab loading and welding device offers higher safety compared to laser welding, preventing hydrogen sulfide from being ignited by the laser beam, further enhancing the safety of solid-state battery production lines.

[0029] Specifically, such as Figure 3 As shown, the tab storage assembly 20 includes a first linear module 21 and a storage rack 22 disposed at the drive end of the first linear module 21. For example, the second linear module 33 can adopt a structure of a motor and a lead screw. The storage rack 22 forms a receiving space for placing tabs, and multiple tabs are stacked within the storage rack 22. An anti-stacking brush 23 is provided at the top outlet of the storage rack 22. The second linear module 33 moves the storage rack 22 to the tab transfer assembly 30. When the tab transfer assembly 30 picks up a tab, the anti-stacking brush 23 prevents multiple tabs from being simultaneously picked up and transferred, ensuring that the tab transfer assembly 30 picks up a single tab.

[0030] In the above scheme, an NG sorting box 24 is also provided on one side of the storage rack 22, and a barcode scanner 70 is also provided on one side of the tab sheet storage component 20. When the tab sheet transfer component 30 picks up the tab sheets for feeding, it scans and registers the tab sheets with the barcode scanner 70. When an unqualified tab sheet is identified, the tab sheet is transferred to the NG sorting box 24.

[0031] Furthermore, the integrated device in this embodiment also includes a transfer station 60, such as... Figure 6 As shown, the transfer station 60 is set between the tab sheet transfer assembly 30 and the tab sheet transfer assembly 40. The tab sheet transfer assembly 30 first grabs the tab sheet from the storage rack 22 and transfers it to the transfer station 60. Then, the tab sheet transfer assembly 40 transfers the tab sheet to the welding assembly 50. The welding assembly 50 then performs ultrasonic welding on the battery cell and the electrode.

[0032] Specifically, in order to achieve the transfer of tabs within the tab storage assembly 20, such as... Figure 4 As shown, the tab sheet transfer assembly 30 includes a mounting frame 31, a movable plate 32 slidably mounted on the mounting frame 31, and a second linear module 33 mounted on the mounting frame 31 and connected to the movable plate 32. At least one set of adsorption components 34 is mounted on the movable plate 32. For example, the second linear module 33 employs a motor and lead screw structure, and the movable plate 32 is slidably mounted on the mounting frame 31 via a slide rail. The second linear module 33 drives the movable plate 32 to move, causing the adsorption components 34 to move above the tab sheet storage assembly 20, thereby adsorbing tab sheets from the storage rack 22.

[0033] Furthermore, in the above solution, the adsorption assembly 34 includes a first driver 341 mounted on the movable plate 32 and an adsorption element 342 disposed at the driving end of the first driver 341. For example, the first driver 341 is a cylinder, which drives the adsorption element 342 to move up and down, thereby causing the adsorption element 342 to extend into the storage rack 22 to pick up the tabs.

[0034] In the above scheme, two sets of adsorption components 34 are provided on the moving plate 32, and the transfer platform 60 is located between the tab sheet storage component 20 and the tab sheet transfer component 40. Then, one set of adsorption components 34 transfers the tab sheets in the tab sheet storage component 20 to the transfer platform 60. At this time, the other set of adsorption components 34 transfers the transfer platform 60 to the tab sheet transfer component 40. The two sets of adsorption components 34 move synchronously. The transfer platform 60 is used to position the tab sheets.

[0035] Specifically, the transfer station 60 includes a placement rack 62 and a placement platform 61 disposed on the placement rack 62. An adjuster 63 is disposed on the placement rack 62 on one side of the placement platform 61. For example, the adjuster 63 includes an adjusting cylinder and a positioning block connected to the driving end of the adjusting cylinder. After the adsorption assembly 34 transfers the tabs from the tab storage assembly 20 to the placement platform 61, the adjuster 63 pushes the tabs on the placement platform 61 to perform positioning, thereby ensuring that the subsequent adsorption assembly 34 can accurately transfer the tabs to the solid-state battery's soldering area.

[0036] Furthermore, such as Figure 5 As shown, the Tab sheet transfer assembly 40 includes a third linear module 41, a mounting base 42 disposed at the moving end of the third linear module 41, a second driver 43 disposed on the mounting base 42, and a clamping assembly 44 disposed on the driving end of the second driver 43. For example, the third linear module 41 adopts a structure of a motor and a lead screw. When the Tab sheet transfer assembly 30 transfers the Tab sheet from the transfer table 60 to the Tab sheet transfer assembly 40, the clamping assembly 44 clamps the Tab sheet, and then the third linear module 41 drives the mounting base 42 to move, causing the clamping assembly 44 to move the Tab sheet to the solid-state battery welding area of ​​the welding assembly 50.

[0037] Specifically, the clamping assembly 44 includes a third driver 442 disposed on the driving end of the second driver 43, and a gripper 441 disposed on the driving end of the third driver 442. For example, the second driver 43 is a bidirectional cylinder, which drives the two grippers 441 to clamp or open towards each other, thereby completing the clamping and releasing action of the tab.

[0038] Furthermore, after the tab sheet moves to the welding assembly 50, the solid-state battery and the tab sheet are ultrasonically welded by the welding assembly 50. For this purpose, the welding assembly 50 includes a support platform 51 and a welder 52 mounted on the frame 10. A pressure plate 53 is mounted on the frame 10 above the support platform 51. After the solid-state battery is placed on the support platform 51, it is pressed down and fixed by the pressure plate 53. After the tab sheet is fed into the area to be welded by the solid-state battery, the welder 52 performs ultrasonic welding on the tab sheet and the solid-state battery. A pressure cylinder 54 is mounted on the frame 10, which drives the pressure plate 53 to press down or release the solid-state battery.

[0039] In the above scheme, a dust removal chamber is provided on the bearing platform 51. The dust removal chamber is connected to the air extraction device through the dust removal channel 55 to remove dust from the solid-state battery during the welding process.

[0040] On the other hand, this embodiment also provides a solid-state battery production equipment, including the aforementioned integrated tab sheet loading and welding device. The integrated device loads the tab sheets simultaneously as the solid-state battery moves to the welding station, ensuring that the solid-state battery and tab sheets arrive at the welding station synchronously. Welding is then performed by the welding assembly, eliminating the need for an additional tab sheet loading station, shortening the process time, and thus improving production efficiency. It also increases the space utilization of the solid-state battery production equipment.

[0041] In summary, in one or more embodiments of this application, this application provides a Tab sheet storage assembly on one side of the frame, a Tab sheet transfer assembly and a welding assembly on the frame 10, and a Tab sheet transfer assembly on the frame between the Tab sheet storage assembly and the Tab sheet transfer assembly. After the battery cell is loaded onto the welding assembly, the Tab sheet on the Tab sheet storage assembly is transferred to the Tab sheet transfer assembly via the Tab sheet transfer assembly, and then transferred to the battery cell on the welding assembly via the Tab sheet transfer assembly. Thus, the Tab sheet loading operation is completed simultaneously with the battery cell moving to the welding station, allowing the battery cell and Tab sheet to arrive at the welding station synchronously. The welding assembly then performs ultrasonic welding on the battery cell and Tab sheet, thereby achieving an integrated production process of Tab sheet loading and welding. This eliminates the need for an additional Tab sheet loading station, avoiding the problems of long transportation time and low production efficiency caused by separating Tab sheet loading and welding into two separate stations, while also improving the space utilization of solid-state battery production equipment.

[0042] 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.
