Description

Technical Field

[0001] This utility model relates to the field of lithium battery adhesive technology, and in particular to cutting and adhesive application equipment for lithium battery processing. Background Technology

[0002] Lithium-ion batteries, as a type of rechargeable battery, have excellent charge and discharge characteristics and are widely used in daily life. During lithium-ion battery production, after the cell and tabs are welded together, blue adhesive is applied to both sides of the tabs to protect the welded areas. However, existing lithium-ion battery tab application mechanisms are mostly complex in structure, requiring two stations to complete the entire application process, which affects the efficiency of tab application. Furthermore, the transfer between tab stations can cause uneven application of adhesive on the upper and lower sides, thus affecting the quality of the processed battery. Therefore, it is necessary to design a new lithium-ion battery tab application mechanism that optimizes the existing structure to simultaneously apply adhesive to both sides of the tabs at a single station, ensuring uniform application while improving efficiency.

[0003] The utility model application CN202420206543.8 discloses a novel lithium battery tab adhesive application mechanism, including a base plate, a mounting plate, a cutting assembly, a guiding and fixing assembly, a clamping and stretching assembly, and an adsorption adhesive application assembly. The base plate has symmetrically arranged side plates on its top two sides, and a mounting plate is arranged on the top and bottom of one side of each side plate. The mounting plate is respectively equipped with the cutting assembly, the guiding and fixing assembly, the clamping and stretching assembly, and the adsorption adhesive application assembly. The cutting assembly consists of a cutting cylinder, a blade connecting plate, and a cutting blade. This utility model utilizes the symmetrically arranged mounting plates on the side plates to fix and support two sets of cutting assemblies, guiding and fixing assemblies, clamping and stretching assemblies, adsorption adhesive application assemblies, and cutting cylinders. During processing, adhesive application can be performed simultaneously on both the upper and lower surfaces of the tab at a single station, improving the efficiency of tab adhesive application and preventing the uniformity of adhesive application on both surfaces from being affected by the shifting of the tab application station, thus ensuring the quality of the processed battery.

[0004] Existing adhesive application equipment used in the lithium battery field often has some limitations. For example, the existing adhesive suction head is flat, which can cause air bubbles when delivering adhesive to the battery cell. Summary of the Invention

[0005] The purpose of this invention is to provide a cutting and gluing device for lithium battery processing, addressing the shortcomings of existing technologies.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A cutting and adhesive application device for lithium battery processing includes a cutting mechanism and an adhesive application mechanism located above the cutting mechanism. The adhesive application mechanism includes a longitudinally arranged adhesive application drive plate. The adhesive application drive plate is equipped with an adsorption component and a rolling component. The adsorption component includes an adsorption seat and an adsorption surface formed on the adsorption seat. The adsorption surface is arranged at an angle and has multiple adsorption holes. The rolling component includes guide rollers that can move longitudinally along the adhesive application drive plate.

[0008] Furthermore, the adhesive application mechanism also includes a moving drive component that drives the adhesive application drive plate to move in the Y-axis and Z-axis directions. The moving drive component includes a Y-axis linear module, and a longitudinally arranged Z-axis linear module is installed at the drive end of the Y-axis linear module. The adhesive application drive plate is installed at the drive end of the Z-axis linear module.

[0009] Furthermore: The drive end of the Z-axis linear module is equipped with a Z-axis moving base, and distance sensors are arranged at intervals along the Z-axis linear module. The Z-axis moving base is equipped with sensing plates that cooperate with the distance sensors.

[0010] Furthermore, the adsorption assembly also includes a drive block installed at the bottom of the adhesive drive plate, an adsorption seat installed at the bottom of the drive block, and an air pipe connector installed on the drive block, with the bottom of the air pipe connector connected to the adsorption seat.

[0011] Furthermore, the rolling assembly also includes a roller seat for mounting the guide roller, the bottom of which is formed with a roller groove, and the guide roller is rotatably mounted in the roller groove.

[0012] Furthermore: the adhesive application drive board is equipped with a rolling lifting seat connected to the roller seat, and a compression spring is connected between the rolling lifting seat and the roller seat.

[0013] Furthermore: there are two rolling lifting seats, and the two rolling lifting seats are arranged with a gap between them. The roller seat is longitudinally aligned with the rolling lifting seats and arranged with a gap between them. The top of the roller seat is formed with a guide block located between the two rolling lifting seats.

[0014] Furthermore, the rolling assembly also includes a rolling drive component that drives the rolling lifting seat to move longitudinally. The rolling drive component includes a rolling guide rail arranged longitudinally along the adhesive application drive plate, and the rolling lifting seat is slidably mounted on the rolling guide rail. The adhesive application drive plate is longitudinally arranged with a rolling telescopic cylinder, and the driving end of the rolling telescopic cylinder is connected to the rolling lifting seat.

[0015] Furthermore, the cutting mechanism includes a cutting blade capable of longitudinal movement and a guide structure for guiding the movement of the cutting blade.

[0016] Furthermore, the cutting mechanism also includes a mounting blade holder for mounting the cutting blade and a longitudinal drive component for driving the mounting blade holder to move longitudinally. The mounting blade holder includes a mounting base and a mounting piece connected to the mounting base. Between the mounting base and the mounting piece, the inner side of the mounting piece is formed with a mounting blade groove for the cutting blade to be embedded and mounted.

[0017] The beneficial effects of this utility model are as follows: Before the film is cut, the adsorption component descends and adsorbs the film through the adsorption holes on the adsorption surface. After cutting, the adhesive applicator transfers the film to the adhesive applicator station and applies it to the battery. During application, the adsorption surface of the adsorption seat contacts the battery wire, and the resulting inclined surface allows airflow to blow out, which is beneficial for the application of the film. Subsequently, the adsorption seat moves horizontally, and at the same time, the guide roller rolls and applies the tape, ensuring a firm application. The guide roller can automatically adjust its level according to the slight changes on the surface of the battery cell, thereby achieving precise application between the guide roller and the battery cell without increasing costs.

[0036] The present invention will now be described in detail with reference to the accompanying drawings.

[0037] like Figure 1-5 As shown, the lithium battery processing cutting and adhesive application equipment includes a cutting mechanism 4 and an adhesive application mechanism 1 located above the cutting mechanism 4. The adhesive application mechanism 1 includes a longitudinally arranged adhesive application drive plate 11. The adhesive application drive plate 11 is equipped with an adsorption component 2 and a rolling component 3. The adsorption component 2 includes an adsorption seat 21 and an adsorption surface 22 formed on the adsorption seat 21. The adsorption surface 22 is arranged at an angle and has a plurality of adsorption holes 23. The rolling component 3 includes a guide roller 33 that can move longitudinally along the adhesive application drive plate 11.

[0038] Before the film is cut, the adsorption component 2 descends and adsorbs the film through the adsorption holes 23 of the adsorption surface 22. After cutting, the adhesive applicator 1 transfers the film to the adhesive applicator station and applies it to the battery. During the application, the adsorption surface 22 of the adsorption seat 21 contacts the battery wire, and the resulting slope allows airflow to blow out, which is beneficial for the application of the film. Subsequently, the adsorption seat 21 moves horizontally, while the guide roller 33 rolls and applies the tape to ensure a firm application. The guide roller 33 can automatically adjust its level according to the slight changes in the surface of the battery cell, thereby achieving precise application between the guide roller 33 and the battery cell without increasing costs.

[0039] The cutting mechanism 4 includes a cutting blade 41 capable of longitudinal movement and a longitudinal drive member for longitudinally moving a blade holder 42. When it is necessary to cut the tape, the cutting blade 41 moves longitudinally under the drive of the longitudinal drive member.

[0040] Specifically, the cutting mechanism 4 also includes a mounting knife holder 42 for mounting the cutting knife 41 and a longitudinal drive member for driving the mounting knife holder 42 to move longitudinally. The mounting knife holder 42 includes a mounting base 43 and a mounting piece 44 connected to the mounting base 43. Between the mounting base 43 and the mounting piece 44, the inner side of the mounting piece 44 is formed with a mounting knife groove 45 for the cutting knife 41 to be embedded and mounted. The cutting knife 41 is mounted between the mounting base 43 and the mounting piece 44 through the mounting knife groove 45, thereby fixing the cutting knife 41. Under the drive of the longitudinal drive member, the mounting knife holder 42 can move up and down to cut the transversely arranged tape.

[0041] Specifically, the longitudinal drive component includes a longitudinally arranged longitudinal guide rail 46 and a longitudinal telescopic cylinder 47 arranged parallel to the longitudinal guide rail 46. A longitudinal moving plate 48 is slidably mounted on the longitudinal guide rail 46, and a blade holder 42 is mounted on the longitudinal moving plate 48. The drive end of the longitudinal telescopic cylinder 47 is connected to the longitudinal moving plate 48. Driven by the longitudinal telescopic cylinder 47, the longitudinal moving plate 48 moves up and down along the longitudinal guide rail 46, thereby driving the cutting blade 41 mounted on the mounting base 43 to move up and down to cut the transversely arranged tape.

[0042] The adhesive application mechanism 1 also includes a moving drive component 12 that drives the adhesive application drive plate 11 to move in the Y-axis and Z-axis directions. The moving drive component 12 includes a Y-axis linear module 13, and a longitudinally arranged Z-axis linear module 14 is mounted on the drive end of the Y-axis linear module 13. The adhesive application drive plate 11 is mounted on the drive end of the Z-axis linear module 14. Driven by the Y-axis linear module 13 and the Z-axis linear module 14, the adhesive application drive plate 11 can move in the Y-axis and Z-axis directions to achieve positional adhesive application, or it can be precisely moved above the cutting mechanism 4 to be coaxially aligned with the film to be cut.

[0043] Furthermore, a Z-axis moving base 15 is installed at the drive end of the Z-axis linear module 14. Distance sensors 16 are arranged at intervals along the Z-axis linear module 14. A sensing plate 17 that senses and cooperates with the distance sensors 16 is installed on the Z-axis moving base 15. When the Z-axis moving base 15 moves up and down in the length direction of the Z-axis linear module 14, the sensing plate 17 of the Z-axis moving base 15 will move between the two distance sensors 16. The distance sensor 16 has a limiting function. After moving into position, the distance sensor 16 and the sensing plate 17 sense and cooperate with each other and will send a pulse signal to the Z-axis linear module 14. At this time, the Z-axis linear module 14 will not continue to move in the same direction to prevent the movement from exceeding the stroke.

[0044] Furthermore, the adsorption assembly 2 also includes a drive block 24 installed at the bottom of the adhesive drive plate 11, an adsorption seat 21 installed at the bottom of the drive block 24, and an air pipe connector 25 installed on the drive block 24. The bottom of the air pipe connector 25 is connected to the adsorption seat 21. The top of the air pipe connector 25 is connected to the air pipe, so that the gas from the air pipe can be introduced into the air pipe connector 25. An air cavity 26 is formed inside the adsorption seat 21. The air cavity 26 is connected to the adsorption hole 23, thereby forming a negative pressure, which can adsorb the film and prevent the film from falling off.

[0045] Furthermore, the rolling assembly 3 also includes a roller seat 31 for mounting the guide roller 33. The bottom of the roller seat 31 is formed with a roller groove 32, and the guide roller 33 is rotatably mounted in the roller groove 32. The two ends of the guide roller 33 are rotatably connected to the roller groove 32 through shaft holes, allowing the guide roller 33 to rotate in the roller groove 32. After the adsorption seat 21 contacts the adhesive tape with the battery cell body wire, the adsorption seat 21 moves laterally, while the guide roller 33 rolls and adheres the adhesive tape, ensuring a firm adhesion. The guide roller 33 is designed as a follow-up structure, allowing it to automatically adjust its level according to minute changes in the surface of the battery cell body, thereby achieving precise adhesion between the guide roller 33 and the battery cell without increasing costs.

[0046] Preferably, the adhesive application drive plate 11 is provided with a rolling lifting seat 35 connected to the roller seat 31, and a compression spring 34 is connected between the rolling lifting seat 35 and the roller seat 31. Under the elastic drive of the compression spring 34, when the guide roller 33 is in contact with the battery cell, it has a buffering effect to prevent excessive impact from damaging the battery cell.

[0047] Preferably, there are two rolling lifting seats 35, which are spaced apart. The roller seat 31 is longitudinally aligned with and spaced apart from the rolling lifting seats 35. A guide block 36 is formed on the top of the roller seat 31 between the two rolling lifting seats 35. During rolling, the guide roller 33 installed on the roller seat 31 contacts the battery cell and is then continuously pressed down. The guide block 36 formed on the top of the roller seat 31 slides through the gap between the two rolling lifting seats 35 to guide the roller seat 31, ensuring that the roller seat 31 moves vertically and ensuring the stability of the movement.

[0048] Preferably, the rolling assembly 3 further includes a rolling drive component that drives the rolling lifting seat 35 to move longitudinally. The rolling drive component includes a rolling guide rail 37 arranged longitudinally along the adhesive application drive plate 11, and the rolling lifting seat 35 is slidably mounted on the rolling guide rail 37. A rolling telescopic cylinder 38 is arranged longitudinally on the adhesive application drive plate 11, and the driving end of the rolling telescopic cylinder 38 is connected to the rolling lifting seat 35. When rolling is required, the rolling telescopic cylinder 38 mounted on the adhesive application drive plate 11 drives the rolling lifting seat 35 to press down, and then the guide roller 33 is bonded to the battery cell. The guide block 36 formed on the top of the roller seat 31 slides and guides the gap between the two rolling lifting seats 35, ensuring that the roller seat 31 moves in the vertical direction and ensuring the stability of the movement.

[0049] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0050] The above description is only a preferred embodiment of this utility model.

The content of this specification should not be construed as a limitation of this utility model.
