Description

Technical Field

[0001] This application relates to the field of adhesive application equipment technology, and in particular to an adhesive application device for double-sided synchronous adhesive application and solid-state battery production equipment. Background Technology

[0002] In existing battery production, there is a process that requires welding tabs onto the battery. After welding the tabs onto the battery, adhesive needs to be applied to both sides of the welding area. The current adhesive application method involves one adhesive application mechanism first applying adhesive to the upper surface of the welding area, and then conveying it to another adhesive application mechanism to apply adhesive to the lower surface of the welding area. This separate adhesive application method is prone to inconsistent adhesive tape sizes when pulling the adhesive, resulting in poor consistency in battery adhesive application. Utility Model Content

[0003] To address one of the aforementioned technical problems, this application provides a double-sided synchronous adhesive application device, including a frame, a clamping assembly disposed on the frame for holding a battery, a tape feeding assembly disposed on one side of the frame near the clamping assembly, at least one synchronous adhesive application assembly disposed between the clamping assembly and the tape feeding assembly, and adhesive application assemblies disposed on both the upper and lower sides of the frame near the clamping assembly. The adhesive application assemblies are used to pick up the tape from the tape feeding assembly and apply it to both sides of the battery on the clamping assembly. By simultaneously pulling two tapes from the tape feeding assembly using the synchronous adhesive application assembly, consistent tape lengths are ensured. Then, the adhesive application assemblies pick up the tape from the tape feeding assembly and simultaneously apply it to both sides of the battery welding position on the clamping assembly, ensuring consistent adhesive application lengths, improving battery product consistency, and saving space occupied by the application device.

[0004] Preferably, the synchronous tape-pulling assembly includes a movable module mounted on the frame, at least two sets of clamping drive components disposed on the movable module, and grippers mounted on the driving ends of the clamping drive components. The clamping drive components are cylinders, which drive the grippers to clamp the tape, and the movable module drives the clamping drive components and grippers to move, thereby synchronously pulling out two tapes of equal length.

[0005] Preferably, the moving module includes a displacement drive component mounted on the frame and a moving plate slidably disposed on the frame. The driving end of the displacement drive component is connected to the moving plate, and the clamping drive component is mounted on the moving plate. The displacement drive component then drives the moving plate to move, causing the grippers to grasp the tape and pull it out.

[0006] Preferably, the tape feeding assembly includes a tape feeding assembly mounted on the frame, a pressure plate assembly and a tape cutting assembly disposed between the tape feeding assembly and the tape pulling assembly. After the tape pulling assembly pulls the tape to a certain length, the pressure plate assembly limits the tape, and then the tape cutting assembly cuts the tape, thus completing the tape cutting action.

[0007] Preferably, the tape-cutting assembly includes a first driver, a lifting frame disposed at the driving end of the first driver, and a cutter disposed on the lifting frame. After the tape-pulling assembly pulls the tape out to a certain length, it moves up and down via the first driver and the lifting frame, thereby causing the cutter to cut the tape.

[0008] Preferably, the pressure plate assembly includes a support platform disposed between the tape cutting assembly and the tape feeding assembly, a tape limiting plate slidably disposed on the frame, and a second driver for driving the tape limiting plate. The second driver drives the tape limiting plate closer to or further away from the tape, thereby effectively limiting the tape during transport and also limiting the tape when it is cut by the cutter.

[0009] Preferably, the tape feeding assembly includes a roll of tape mounted on the frame and a plurality of guide rollers, the guide rollers being used to guide the tape to the tape cutting assembly. The tape is continuously fed to the tape cutting assembly via the guide rollers, the tape pulling assembly pulls the tape out, and then the tape is cut by the tape cutting assembly.

[0010] Preferably, the adhesive application assembly includes a linear motion module and a lifting drive component disposed on the linear motion module. An adsorption plate is disposed at the driving end of the lifting drive component, and an adsorption port is provided at the end of the adsorption plate. Then, after the adhesive pulling assembly pulls out the adhesive tape, it adsorbs the tape through the adsorption port at the end of the adsorption plate. The adhesive cutting assembly then cuts the tape, and finally, the linear motion module drives the adsorption plate to move to the battery welding area for adhesive application.

[0011] Preferably, the clamping assembly includes a clamping driver disposed on the frame and a clamping block disposed on the driving end of the clamping driver. The clamping driver can be a cylinder, so that after the battery is moved into place, the clamping driver drives the clamping block to clamp and fix the battery, preventing the battery from shifting during the adhesive application process and improving the accuracy of the adhesive application position.

[0012] Preferably, a solid-state battery production equipment includes the aforementioned double-sided synchronous adhesive application device. Compared to the existing method of applying adhesive in two separate steps using two different application mechanisms, this adhesive application device saves equipment space and ensures consistent adhesive application length, thus improving the consistency of battery products.

[0013] Compared with the prior art, the beneficial effects of this application are as follows: This application provides a clamping assembly for holding the battery within a frame, a tape feeding assembly on one side of the frame located from the clamping assembly, and a synchronous tape pulling assembly between the clamping assembly and the tape feeding assembly. The synchronous tape pulling assembly simultaneously pulls two tapes from the tape feeding assembly, ensuring consistent tape lengths. Adhesive application assemblies are located above and below the clamping assembly on the frame. These adhesive application assemblies pick up the tape from the synchronous tape pulling assembly and simultaneously apply it to both sides of the battery welding position on the clamping assembly, ensuring consistent tape lengths, improving the consistency of solid-state battery products, and saving space occupied by the adhesive application device.

[0028] 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:

[0029] To address the aforementioned technical problems, this embodiment provides a double-sided synchronous adhesive application device, such as... Figure 1-3As shown, the device includes a frame 50, on which a clamping assembly 10 for holding the battery is provided. A tape feeding assembly 40 is located on one side of the frame 50 near the clamping assembly 10. A synchronous tape-pulling assembly 30 is positioned between the clamping assembly 10 and the tape feeding assembly 40, allowing two tapes to be pulled simultaneously from the tape feeding assembly 40, ensuring consistent tape lengths. Adhesive-applying assemblies 20 are located on both the upper and lower sides of the frame 50 near the clamping assembly 10. These assemblies pick up the tape from the synchronous tape-pulling assembly 30 and simultaneously apply it to both sides of the battery welding position on the clamping assembly 10, ensuring consistent tape lengths for fixing the battery, improving the consistency of solid-state battery adhesive application, and saving space occupied by the adhesive application device.

[0030] It should be noted that the double-sided synchronous adhesive application device of this application is suitable for solid-state batteries and is used to apply adhesive to both sides of the solid-state battery simultaneously to ensure the consistency of adhesive application.

[0031] Specifically, after the solid-state battery moves horizontally to the clamping assembly 10, the clamping assembly 10 clamps and fixes the battery. Simultaneously, the adhesive application assembly 30, positioned above and below the battery, pulls two adhesive tapes from the tape feeding assembly 40. The adhesive application assembly 20 then picks up the two tapes and simultaneously applies them to both sides of the solid-state battery. Furthermore, the clamping assembly 10 includes a clamping driver 11 mounted on the frame 50 and a clamping block 12 mounted on the driving end of the clamping driver 11. The clamping driver 11 can be a cylinder. After the solid-state battery is moved into position, the clamping driver 11 drives the clamping block 12 to clamp and fix the solid-state battery, preventing displacement during adhesive application and improving the accuracy of the adhesive application position.

[0032] Specifically, such as Figure 4 As shown, the synchronous tape-pulling assembly 30 includes a movable module 31 mounted on a frame 50, at least two sets of clamping drive members 32 disposed on the movable module 31, and grippers 33 mounted on the driving end of the clamping drive members 32. For example, the clamping drive members 32 are cylinders. The clamping drive members 32 drive the grippers 33 to clamp the tape, and the movable module 31 drives the clamping drive members 32 and the grippers 33 to move, thereby synchronously pulling out two tapes of equal length.

[0033] Furthermore, the mobile module 31 includes a displacement drive 311 mounted on the frame 50 and a movable plate 312 slidably mounted on the frame 50. The driving end of the displacement drive 311 is connected to the movable plate 312, and a clamping drive 32 is mounted on the movable plate 312. The displacement drive 311 drives the movable plate 312 to move, causing the grippers 33 to clamp the tape and pull it out. Specifically, by arranging two clamping drive 32 at intervals on the movable plate 312, and then using the displacement drive 311 to drive the movable plate 312 to move, the grippers 33 of the two clamping drive 32 pull the tape simultaneously, thereby achieving the function of synchronous tape pulling on both sides and ensuring the consistency of tape length, thus improving the consistency of solid-state battery adhesive application.

[0034] In the above scheme, the tape feeding assembly 40 includes a tape feeding assembly 42 mounted on the frame 50, a pressure plate assembly 43 and a tape cutting assembly 41 positioned between the tape feeding assembly 42 and the synchronous tape pulling assembly 30. The tape feeding assembly 42 feeds the tape to the pressure plate assembly 43 and the tape cutting assembly 41. After the synchronous tape pulling assembly 30 pulls the tape out to a certain length, the pressure plate assembly 43 limits the tape, and then the tape cutting assembly 41 cuts the tape, thus completing the tape picking action. Since the synchronous tape pulling assembly 30 pulls out two tapes simultaneously, two sets of the tape applicator 20, the pressure plate assembly 43, and the tape cutting assembly 41 are each provided, and are symmetrically arranged on both sides of the solid-state battery.

[0035] Specifically, such as Figure 5 As shown, the tape cutting assembly 41 includes a first driver 413, a lifting frame 412 disposed at the driving end of the first driver 413, and a cutter 411 disposed on the lifting frame 412. For example, the first driver 413 is a cylinder. After the synchronous tape pulling assembly 30 pulls the tape out to a certain length, the lifting frame 412 of the first driver 413 moves up and down, thereby causing the cutter 411 to cut the tape.

[0036] Furthermore, such as Figure 6-7 As shown, the pressure plate assembly 43 includes a support platform 431 disposed between the tape cutting assembly 41 and the tape feeding assembly 42, a tape limiting plate 432 slidably disposed on the frame 50, and a second driver 433 for driving the tape limiting plate 432. For example, the second driver 433 is a cylinder. The second driver 433 drives the tape limiting plate 432 to move closer to or away from the tape, thereby effectively limiting the tape during the tape transfer process and also limiting the tape when the cutter 411 cuts the tape.

[0037] Furthermore, the tape feeding assembly 42 includes a tape feeding 421 mounted on the frame 50 and several guide rollers 422. The guide rollers 422 are used to guide the tape to the tape cutting assembly 41. The tape is continuously fed to the tape cutting assembly 41 through the guide rollers 422. The tape is then pulled out by the synchronous tape pulling assembly 30 and cut by the tape cutting assembly 41.

[0038] In the above solution, in order to attach the tape to both sides of the solid-state battery, such as... Figure 8 As shown, the adhesive application assembly 20 includes a linear motion module 21 and a lifting drive component 23 mounted on the linear motion module 21. An adsorption plate 22 is mounted at the driving end of the lifting drive component 23, and an adsorption port 24 is provided at the end of the adsorption plate 22. For example, the lifting drive component 23 is a cylinder. The lifting drive component 23 drives the adsorption plate 22 to move up and down, causing the end of the adsorption plate 22 to move towards the synchronous adhesive application assembly 30. The synchronous adhesive application assembly 30 then pulls out the adhesive tape, which is then adsorbed through the adsorption port 24 at the end of the adsorption plate 22. The adhesive tape is then cut by the adhesive cutting assembly 41. The linear motion module 21 then drives the adsorption plate 22 to move towards the solid-state battery, and the lifting drive component 23 drives the adsorption plate 22 towards the solid-state battery, thus applying the adhesive tape to the surface of the solid-state battery. Two sets of adhesive application assemblies 20 are mounted on the frame 50, allowing both sets of adhesive application assemblies 20 to simultaneously pick up two pieces of adhesive tape and apply them to both sides of the solid-state battery, improving the adhesive application efficiency.

[0039] On the other hand, this solution provides a solid-state battery production equipment, including the aforementioned double-sided synchronous adhesive application device. This device applies adhesive to both sides of the solid-state battery simultaneously. Compared to the existing method of applying adhesive twice separately using two different adhesive application mechanisms, this device saves space and ensures consistent adhesive application length. This not only improves the consistency of adhesive application but also prevents fatigue fracture at the solder joints. Specifically, the adhesive tape at both ends distributes stress, reducing fatigue at the solder joints and increasing the mechanical fixing strength between the tabs and the cell, thus preventing tab detachment and further improving the reliability and yield of the solid-state battery.

[0040] In summary, in one or more embodiments of this application, the solution includes a clamping assembly for holding the battery on a frame, a tape feeding assembly on one side of the frame near the clamping assembly, and a synchronous tape pulling assembly between the clamping assembly and the tape feeding assembly. The synchronous tape pulling assembly simultaneously pulls two tapes from the tape feeding assembly, ensuring consistent tape lengths. Adhesive application assemblies are located above and below the clamping assembly on the frame. These adhesive application assemblies pick up the tape from the synchronous tape pulling assembly and simultaneously apply it to both sides of the battery welding position on the clamping assembly, ensuring solid-state bonding.

[0041] Consistent adhesive tape lengths improve the uniformity of solid-state battery products while saving space occupied by the tape application device.

[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.
