In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In the present invention, unless otherwise specified, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the drawings; while "inside" and "outside" refer to the outline of the device.

[0052] The battery pole piece thermal composite process is to heat the thermal composite roller, and use the thermal composite roller to composite the positive pole piece, the diaphragm and the negative pole piece together to form a thermal composite pole piece assembly. In the related art, in continuous production, foreign matter such as the ceramic coating and composite glue on the diaphragm will adhere to the thermal composite roller, which will cause the thermal composite pole piece assembly to be delaminated or indented, and then cause serious quality problems in the core package formed by stacking the thermal composite pole piece assembly.

[0053] The embodiment of the present application provides a thermal composite roller device, such as Figure 1 As shown, the thermal laminating roller device 10 includes a thermal laminating mechanism 1 and a cleaning mechanism 2 .

[0054] The thermal composite mechanism 1 comprises a frame 11 , a thermal composite roller assembly 12 , and a thermal composite roller driving assembly 13 .

[0055] The frame 11 is provided with a receiving cavity, and the heat compound roller assembly 12 is rotatably installed in the receiving cavity. The frame 11 of the heat compound mechanism 1 includes a first side plate, a second side plate and a first end plate and a second end plate connected between the first side plate and the second side plate. The first side plate, the second side plate, the first end plate and the second end plate enclose a receiving cavity with two sides open, and the heat compound roller assembly 12 is installed in the receiving cavity.

[0056] The hot composite roller assembly 12 includes a first hot composite roller 121 and a second hot composite roller 122, and the first hot composite roller 121 and the second hot composite roller 122 are both rotatably installed in the accommodating cavity of the same frame 11 through a pivot device. The hot composite roller assembly 12 is used to composite the positive electrode sheet, the separator and the negative electrode sheet to be composited by hot composite. A gap is formed between the first hot composite roller 121 and the second hot composite roller 122, and the gap is configured to allow the positive electrode sheet, the separator and the negative electrode sheet to be composited to pass through.

[0057] The heat composite roller driving component 13 is installed on the frame 11. The heat composite roller driving component 13 includes a first heat composite roller driving component 131 and a second heat composite roller driving component 132. The first heat composite roller driving component 131 is connected to the first heat composite roller 121 and is used to drive the first heat composite roller 121 to rotate in a first direction. The second heat composite roller driving component 132 is connected to the second heat composite roller 122 and is used to drive the second heat composite roller 122 to rotate in a second direction, wherein the first direction and the second direction are opposite. The first heat composite roller driving component 131 or the second heat composite roller driving component 132 can be a motor, and the power of the motor is transmitted to the heat composite roller through a coupling as a transmission component. Alternatively, the first heat composite roller driving component 131 or the second heat composite roller driving component 132 can be a hydraulic driving device, and the hydraulic driving force provided by the hydraulic driving device further drives the heat composite roller. Alternatively, the first heat composite roller driving component 131 or the second heat composite roller driving component 132 can also be a pneumatic device, and the pneumatic device drives the heat composite roller to operate with the help of compressed air. Alternatively, the first heat composite roller driving member 131 or the second heat composite roller driving member 132 may also be a mechanical driving device, which drives the heat composite roller to operate through mechanical transmission methods such as gear transmission and belt transmission.

[0058] The cleaning mechanism 2 includes at least one scraper assembly 3 and a driving assembly 4 .

[0059] The scraper assembly 3 includes a scraper 31 , which is arranged to contact with the surface of the hot composite roller and move relative to the hot composite roller on the surface of the hot composite roller to clean foreign matter on the surface of the hot composite roller.

[0060] During the hot composite roller hot composite process, the scraper 31 contacts the surface of the hot composite roller and moves relative to the surface of the hot composite roller to clean the foreign matter on the surface of the hot composite roller, thereby effectively improving the quality problems of the core package formed by the stacked hot composite pole piece assembly formed by hot composite due to the adhesion of foreign matter on the surface of the hot composite roller. It is understandable that since the scraper assembly 3 is mobile cleaning, even if there is wear or damage to a part of the scraper 31, the scraper assembly 3 as a whole can fully clean the hot composite roller during the process of the scraper 31 moving and cleaning.

[0061] In some implementations, the cleaning mechanism 2 includes a scraper assembly 3 and a drive assembly 4, wherein the drive assembly 4 is connected to the scraper assembly 3 and is used to drive the scraper assembly 3 to move unidirectionally or bidirectionally on the surface of the hot composite roller along the axial direction of the hot composite roller relative to the hot composite roller. Figure 3In the X direction shown, the hot composite roller includes a top end face and a bottom end face that are opposite to each other along the axial direction X of the composite roller. The single-line movement of the scraper assembly 3 along the axial direction X of the hot composite roller is represented by the scraper assembly moving from the side close to the top end face to the side close to the bottom end face along the axial direction X of the hot composite roller, or the scraper assembly moving from the side close to the bottom end face to the side close to the top end face along the axial direction X of the hot composite roller. It should be noted that the hot composite roller rotates helically along the axial direction, and the scraper assembly 3 moves linearly relative to the hot composite roller along the axial direction of the hot composite roller.

[0062] The bidirectional movement of the scraper assembly 3 along the axial direction X of the hot composite roller is represented by the scraper assembly moving from the side close to the top end surface to the side close to the bottom end surface along the axial direction X of the hot composite roller, and then moving from the side close to the bottom end surface to the side close to the top end surface, so that the entire outer surface of the hot composite roller along the axial direction of the hot composite roller can be effectively cleaned. When the scraper 31 moves to the side close to the bottom end surface of the hot composite roller, the driving force of the driving assembly 4 is changed in the direction, so that the driving assembly 4 drives the scraper 31 from the side close to the bottom end surface to the side close to the top end surface.

[0063] In some embodiments, the drive assembly 4 includes a screw assembly, which includes at least one screw 41 and a screw driver 42. The scraper assembly 3 is fixed on the screw 41, and the screw driver 42 is configured to drive the screw 41 to move along the axial direction X of the hot composite roller.

[0064] The cleaning mechanism 2 further comprises a base, the base is provided with a receiving cavity 22, and the screw rod 41 is rotatably installed in the receiving cavity 22 of the base.

[0065] The screw drive 42 can be a motor, which transmits the power of the motor to the screw through a coupling and other transmission components. The surface of the screw 41 is provided with a threaded structure, and the scraper assembly 3 is fixed on the screw 41. The screw drive 42 drives the screw 41 to rotate and then drives the scraper assembly 3 to move along the axial direction of the screw 41, wherein the axial direction of the screw 41 is set parallel to the axial direction of the hot composite roller.

[0066] The screw drive member 42 is installed on a base, and the base is fixed on a frame 11 installed on the thermal bonding mechanism 1. The base includes a first fixing portion 211 and a second fixing portion 212 relative to each other. The first fixing portion 211 is fixed on a first side plate 111 of the frame 11, and the second fixing portion 212 is fixed on a second side plate 112 of the frame 11.

[0067] Continue to refer Figure 1As shown, the hot composite roller device 10 includes two cleaning mechanisms 2, which are respectively a first cleaning mechanism 201 and a second cleaning mechanism 202. The first cleaning mechanism 201 and the second cleaning mechanism 202 are arranged at intervals. The first cleaning mechanism 201 is arranged corresponding to the first hot composite roller 121 and is used to clean the surface of the first hot composite roller 121. The second cleaning mechanism 202 is arranged corresponding to the second hot composite roller 122 and is used to clean the surface of the second hot composite roller 122, so that both the first hot composite roller 121 and the second hot composite roller 122 are effectively cleaned.

[0068] refer to Figures 1 to 4 In one embodiment provided in the present application, the cleaning mechanism 2 includes two scraper assemblies 3, each of the two scraper assemblies 3 includes a scraper 31, the two scrapers 31 are staggered, and the two scrapers 31 are configured to clean the same hot composite roller. In a specific implementation, the first hot composite roller 121 is correspondingly provided with two scraper assemblies 3, and the second hot composite roller 122 is also correspondingly provided with two scraper assemblies 3.

[0069] The two scraper assemblies 3 for cleaning the same hot composite roller include a first scraper assembly 301 and a second scraper assembly 302, wherein the first scraper assembly 301 and the second scraper assembly 302 are fixed on the same driving assembly 4, and the driving assembly 4 is configured to synchronously drive the first scraper assembly 301 and the second scraper assembly 302 to move and make the moving direction of the first scraper assembly 301 opposite to the moving direction of the second scraper assembly 302, for example, the driving assembly 4 drives the first scraper assembly 301 to move rightward along the axial direction of the hot composite roller relative to the hot composite roller on the surface of the hot composite roller, and correspondingly, the driving assembly 4 drives the second scraper assembly 302 to move leftward along the axial direction of the hot composite roller relative to the hot composite roller on the surface of the hot composite roller, and by setting two scraper assemblies 3 to clean the surface of the same hot composite roller, it can be used to improve the cleaning efficiency of the cleaning mechanism and effectively clean the hot composite roller. The two scraper assemblies 3 are staggered on the surface of the hot composite roller, so that the scraper assembly 3 will not miss cleaning the hot composite roller during the rotation of the hot composite roller.

[0070] Continue to refer Figures 1 to 4 The driving assembly 4 includes two screw rods 41, and the two screw rods 41 include a first screw rod 411 and a second screw rod 412, wherein the thread directions of the first screw rod 411 and the second screw rod 412 are opposite, and the first screw rod 411 and the second screw rod 412 are arranged at an interval, the first scraper assembly 301 is fixed on the first screw rod 411, and the second scraper assembly 302 is fixed on the second screw rod 412, and the first screw rod 411 and the second screw rod 412 are configured to be driven by the same screw rod driving member 42, and the screw rod driving member 42 is configured to drive the first screw rod 411 and the second screw rod 412 to move in opposite directions.

[0071] Two screw fixing holes are provided on the first fixing part 211 and the second fixing part 212 of the base of the cleaning mechanism 2, and the two ends of the first screw rod 411 are respectively connected to one of the screw fixing holes of the first fixing part 211 and one of the screw fixing holes of the second fixing part 212 through pivot rotation, and the two ends of the second screw rod 412 are respectively connected to the other screw fixing hole of the first fixing part 211 and the other screw fixing hole of the second fixing part 212 through pivot rotation.

[0072] The screw drive 42 is fixedly mounted on the first fixed portion 211 or the second fixed portion 212. The screw drive 42 is connected to one end of the first screw 411 and one end of the second screw 412 through a transmission assembly 43. The transmission assembly 43 includes a synchronous belt 431 and two synchronous wheels 432, wherein one synchronous wheel 432 is fixed to one end of the first screw 411, and the other synchronous wheel 432 is fixed to one end of the second screw 412. The synchronous belt 431 is wound around the two synchronous wheels 432. The screw drive 42 drives the two synchronous wheels 432 to rotate, thereby driving the first screw 411 and the second screw 412 to rotate in a spiral manner. The synchronous belt 431 wound around the two synchronous wheels 432 enables the two synchronous wheels 432 to have the same operating frequency. When the screw drive 42 drives the two synchronous wheels 432 to rotate, the two synchronous wheels 432 synchronously drive the first screw 411 and the second screw 412 to rotate. Since the thread directions of the first screw 411 and the second screw 412 are opposite, the first screw 411 drives the first scraper assembly 301 to move to the left along the axial direction of the composite roller, and the second screw 412 drives the second scraper assembly 302 to move to the right along the axial direction of the composite roller.

[0073] The base of the cleaning mechanism 2 also includes a slide rail 23, which is connected between the first fixed portion 211 and the second fixed portion 212 of the base. The scraper assembly 3 includes a scraper 31 and a scraper fixing seat 32. The scraper fixing seat 32 includes a slide groove 321, and the slide groove 321 is configured to slide on the slide rail 23. The scraper fixing seat 32 also includes a screw through hole 322, and the scraper fixing seat 32 is connected to the screw through the screw through hole 322.

[0074] refer to Figure 5 and Figure 6 In one embodiment of the present application, the scraper assembly 3 includes a scraper 31, a scraper fixing seat 32, and a pressing drive assembly 33. The scraper 31 is configured in a sheet shape, and the scraper 31 and the hot composite roller are configured to be in line contact, and the plane where the scraper 31 is located is set at an angle to the axial direction of the hot composite roller. The scraper 31 is rotatably connected to the scraper fixing seat 32 through a pivot structure, and the pressing drive assembly 33 is connected to the scraper 31 and drives the scraper 31 to abut against the surface of the hot composite roller.

[0075] In some embodiments, the pressing drive assembly 33 includes a lifting drive member 331 and a lifting linkage member 332. The lifting drive member 331, the lifting linkage member 332 and the scraper 31 are provided with a lever linkage structure. The lifting drive member 331 is provided to provide a pressing driving force. The lifting linkage member 332 is connected between the scraper 31 and the lifting drive member 331. When the lifting drive member 331 moves upward, the lifting linkage member 332 is driven to move, and the lifting linkage member 332 drives the scraper 31 downward to abut against the surface of the hot composite roller. When the lifting drive member 331 moves downward, the lifting linkage member 332 is driven to move, and the lifting linkage member 332 drives the scraper 31 to bounce upward and leave the surface of the hot composite roller.

[0076] Continue to refer Figure 5 and Figure 6 The lifting linkage member 332 includes a first connecting section 333 and a second connecting section 334 which are bent and connected. One end of the first connecting section 333 is rotatably connected to the lifting driving member 331, and the other end of the first connecting section 333 is connected to one end of the second connecting section 334. The other end of the second connecting section 334 is bent and connected to the scraper 31. The lifting driving member 331 includes a lifting cylinder.

[0078] By arranging the lifting drive member 331, the lifting linkage member 332 and the scraper 31 as a lever connection structure, the lifting drive member 331 provides a smaller driving force to drive the scraper 31 to move toward or away from the surface of the hot composite roller.

[0079] The second connecting section 334 includes a second connecting section first portion 335 and a second connecting section second portion 336, and the second connecting section first portion 335 and the second connecting section second portion 336 are arranged at an acute angle. By arranging the second connecting section 334 at an angle, it is beneficial for the second connecting section 334 to adjust the contact angle between the scraper 31 and the hot composite roller, so that the scraper 31 forms a stable contact with the hot composite roller.

[0080] Continue to refer Figure 3The scraper assembly 3 also includes a dust box 5, which is arranged on one side or both sides of the scraper 31. The dust box 5 is provided with a dust suction port. When the scraper 31 is cleaning the hot composite roller, the foreign matter scraped by the scraper 31 is collected into the dust box 5 through the dust suction port. The dust box 5 is fixedly connected to the scraper fixing seat 32. The dust box 5 includes a receiving portion and a fixing portion, and the receiving portion and the fixing portion are arranged at an angle, so that the receiving portion is located directly below the scraper 31, and the fixing portion is located below the scraper fixing seat 32.
