Adjustable gap composite hot press roller assembly

Abstract

This utility model discloses an adjustable-gap composite hot press roller assembly, relating to the field of current collector technology. It includes a worktable, with a composite box positioned above the surface of the worktable. Both the composite box and the worktable have equidistantly arranged composite mechanisms in their middle sections. Each composite mechanism includes a thermodynamic roller, an adjusting frame, and a power clamp. The thermodynamic roller is rotatably connected to the worktable. A hot press roller is rotatably connected inside the adjusting frame, and an adjusting sleeve is fixedly connected to the surface of the adjusting frame. This adjustable-gap composite hot press roller assembly uses the hot press roller to thermally extrude and composite two metal foils together, improving the convenience and stability of metal foil composite. The adjusting sleeve allows the adjusting frame to move the hot press roller up and down, adjusting the height between the hot press roller and the thermodynamic roller. By gradually reducing the gap between the rollers, the metal foil is gradually hot-pressed, preventing over-pressing and subsequent damage to the metal foil, thus improving the stability of the metal foil composite.

Description

Technical Field

[0001] This utility model relates to the field of current collector technology, specifically to a composite hot press roller assembly with adjustable gap. Background Technology

[0002] A current collector, as the name suggests, refers to a structure or component that collects current. In lithium-ion batteries, this mainly refers to metal foil, such as copper foil or aluminum foil. More generally, it can also include electrode tabs. Its main function is to collect the current generated by the battery's active materials to form a larger current output. Therefore, the current collector should have sufficient contact with the active materials, and its internal resistance should be as low as possible.

[0003] In the process of current collector lamination, composite hot press rollers are used to thermally extrude aluminum foil and copper foil. However, most existing methods use a set of upper and lower composite hot press rollers to extrude the metal foil. During the lamination process, excessive pressure can easily cause damage to the metal foil, increasing the difficulty of current collector lamination. To address this issue, we provide a composite hot press roller set with adjustable gap. Utility Model Content

[0004] The purpose of this invention is to provide a composite hot press roller assembly with adjustable gap to solve the problems raised in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable gap composite hot press roller assembly, including a worktable, a composite box arranged above the surface of the worktable, and composite mechanisms arranged at equal intervals in the middle of both the composite box and the worktable. The composite mechanism includes a thermodynamic roller, an adjusting frame, and a power clamp. The thermodynamic roller is rotatably connected to the worktable, and the power clamp is movably connected to the composite box. The hot press roller is rotatably connected inside the adjusting frame, and an adjusting sleeve is fixedly connected to the surface of the adjusting frame, and the adjusting sleeve is slidably connected to the composite box.

[0006] Preferably, a fixed frame is fixedly connected to the surface of the workbench, and a lifting device for controlling the lifting and lowering of the composite box is fixedly connected inside the fixed frame. A limiting support rod for supporting the composite box is fixedly connected to the surface of the workbench. The limiting support rod supports and positions the composite box to prevent excessive compression of the composite box.

[0007] Preferably, one end of the thermodynamic roller is fixedly connected to a connecting sprocket, and the connecting sprockets are connected in pairs by a chain. The surface of the worktable is fixedly connected to a motor, and the output end of the motor is connected to the adjacent connecting sprockets by a chain. The motor controls the rotation of the connecting sprockets, and through the transmission of the chain and the connecting sprockets, the several thermodynamic rollers rotate synchronously.

[0008] Preferably, the adjusting sleeve is internally threaded with a helical rod, and a worm gear is fixedly connected to the top of the helical rod. The worm gear is rotatably connected to the composite box. The worm gear drives the helical rod to rotate, causing the adjusting sleeve to move the adjusting frame up and down, thus moving the adjusting frame to a suitable height.

[0009] Preferably, a support rod is fixedly connected inside the composite box, a worm gear is meshed with the worm wheel and rotatably connected to the support rod, and a connecting plate is fixedly connected to one end of the worm gear. The rotation of the worm gear controls the slow rotation of the worm wheel, thereby improving the accuracy of the worm wheel in controlling the lifting and lowering of the adjustment frame.

[0010] Preferably, a linkage lever is fixedly connected to the middle of the connecting plate, and the power clamp head is slidably connected to the linkage lever. A telescopic spring is sleeved on the outside of the linkage lever, and the two ends of the telescopic spring are fixedly connected to the connecting plate and the power clamp head respectively. The telescopic spring provides a thrust to the power clamp head, making the limit lever and the limit plate more tightly and stably engaged.

[0011] Preferably, the interior of the composite box is fixedly connected to a limiting disk, and the surface of the power clamp head is fixedly connected to a circumferentially arranged limiting rod, which is engaged with the limiting disk. By engaging the limiting rod and the limiting disk together, the position of the power clamp head is limited, preventing the power clamp head from rotating arbitrarily and improving the stability of the device operation.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This application uses a rotating thermodynamic roller to transport the composite material, and a hot press roller to thermally extrude and bond two metal foils together, improving the convenience and stability of metal foil bonding. By adjusting the sleeve, the adjusting frame drives the hot press roller to move up and down, adjusting the height between the hot press roller and the thermodynamic roller. By controlling the distance between the rollers of the pressure roller group to gradually decrease, the metal foil is gradually hot-pressed, preventing excessive pressing at one time from causing damage to the aluminum and copper foils, and improving the stability of metal foil bonding.

[0014] 2. This application uses a limiting support rod to support and position the composite box, preventing excessive compression of the composite box and causing the hot pressure roller and the thermodynamic roller to come into contact. A fixed frame is used to fix and support the lifting device. The lifting device controls the up and down movement of the composite box, bringing the hot pressure roller and the thermodynamic roller closer together to extrude and thermally composite the metal foil. A motor controls the rotation of the connecting sprocket, and through the transmission of the chain and the connecting sprocket, several thermodynamic rollers rotate synchronously, improving the stability of the thermodynamic roller transmission rotation. A worm gear drives the screw rod to rotate, causing the adjusting sleeve to move the adjusting frame up and down, moving the adjusting frame to the appropriate height value.

[0015] 3. This application uses a support rod to support and fix the worm gear, and controls the slow rotation of the worm wheel by rotating the worm gear, thereby improving the accuracy of the worm wheel's control over the lifting and lowering of the adjusting frame. The rotation of the power chuck causes the connecting rod to drive the worm gear to rotate, improving the stability of the worm gear's rotation. The limit chuck and the limit plate are interlocked to limit the position of the power chuck, preventing the power chuck from rotating arbitrarily and improving the stability of the device's operation. The telescopic spring provides thrust to the power chuck, making the connection between the limit chuck and the limit plate tighter and more stable. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides a technical solution for a composite hot press roller assembly with adjustable gap.

[0023] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4It includes a workbench 1, and a composite box 4 is provided above the surface of the workbench 1. By bringing the workbench 1 and the composite box 4 close to each other, the composite rollers are brought close to each other to composite the metal foil, thereby improving the convenience of the metal foil.

[0024] Both the composite box 4 and the worktable 1 are provided with composite mechanisms 6 arranged at equal intervals in the middle. The composite mechanism 6 includes a thermodynamic roller 601, an adjusting frame 604 and a power clamp 612. The thermodynamic roller 601 is rotatably connected to the worktable 1 and the power clamp 612 is movably connected to the composite box 4. The composite material is transferred by rotating the thermodynamic roller 601, which improves the stability and convenience of material composite.

[0025] The adjusting frame 604 is internally rotatably connected to a hot pressing roller 603, and an adjusting sleeve 605 is fixedly connected to the surface of the adjusting frame 604. The adjusting sleeve 605 is slidably connected to the composite box 4. The hot pressing roller 603 is used to hot-press and composite the two metal foils together, improving the convenience and stability of metal foil composite. The adjusting sleeve 605 is used to move the adjusting frame 604 up and down to adjust the height between the hot pressing roller 603 and the thermal roller 601. By controlling the distance between the rollers of the pressure roller group to gradually decrease, the metal foil is gradually hot-pressed to prevent the aluminum foil and copper foil from being damaged due to excessive pressing at one time, thereby improving the stability of metal foil composite.

[0026] A fixed frame 2 is fixedly connected to the surface of the workbench 1. A lifting device 3 for controlling the lifting and lowering of the composite box 4 is fixedly connected inside the fixed frame 2. A limiting support rod 5 for supporting the composite box 4 is fixedly connected to the surface of the workbench 1. The limiting support rod 5 supports and positions the composite box 4 to prevent excessive compression of the composite box 4, which would cause the hot pressure roller 603 and the thermal power roller 601 to come into contact. The lifting device 3 is fixed and supported by the fixed frame 2. The lifting device 3 controls the up and down movement of the composite box 4, so that the hot pressure roller 603 and the thermal power roller 601 come closer to each other and extrude and thermally composite the metal foil.

[0027] One end of the thermodynamic roller 601 is fixedly connected to a connecting sprocket 602, and the connecting sprockets 602 are connected in pairs via a chain. A motor 7 is fixedly connected to the surface of the worktable 1, and the output end of the motor 7 is connected to the adjacent connecting sprocket 602 via a chain. The motor 7 controls the rotation of the connecting sprocket 602. Through the transmission of the chain and the connecting sprocket 602, several thermodynamic rollers 601 rotate synchronously, improving the stability of the rotation of the thermodynamic roller 601.

[0028] The adjusting sleeve 605 is internally threaded with a spiral rod 606. The top end of the spiral rod 606 is fixedly connected with a worm gear 607, which is rotatably connected to the composite box 4. The worm gear 607 drives the spiral rod 606 to rotate, causing the adjusting sleeve 605 to drive the adjusting frame 604 to move up and down, moving the adjusting frame 604 to a suitable height.

[0029] The composite box 4 is internally fixedly connected to a support rod 609, and a worm gear 607 is meshed with a worm 608. The worm 608 is rotatably connected to the support rod 609. The support rod 609 supports and fixes the worm 608. The rotation of the worm 608 controls the slow rotation of the worm gear 607, thereby improving the accuracy of the worm gear 607 in controlling the lifting and lowering of the adjusting frame 604.

[0030] One end of the worm gear 608 is fixedly connected to a connecting plate 610, and a connecting rod 611 is fixedly connected to the middle of the connecting plate 610. The power clamp 612 is slidably connected to the connecting rod 611. By rotating the power clamp 612, the connecting rod 611 drives the worm gear 608 to rotate, thereby improving the stability of the rotation of the worm gear 608.

[0031] The interior of the composite box 4 is fixedly connected to a limiting disk 615. The surface of the power clamp 612 is fixedly connected to a circumferentially arranged limiting rod 614, and the limiting rod 614 is engaged with the limiting disk 615. By engaging the limiting rod 614 with the limiting disk 615, the position of the power clamp 612 is limited, preventing the power clamp 612 from rotating arbitrarily and improving the stability of the device operation.

[0032] The linkage lever 611 is fitted with a telescopic spring 613, and the two ends of the telescopic spring 613 are fixedly connected to the connecting plate 610 and the power clamp head 612 respectively. The telescopic spring 613 provides a thrust to the power clamp head 612, so that the limit lever 614 and the limit plate 615 are more tightly and stably engaged.

[0033] The lifting device 3, the electric motor 7, the hot pressing roller 603 and the thermal power roller 601 are existing devices. This application will not go into detail about their detailed parameters and models. The metal foil is a metal foil such as aluminum foil or copper foil.

[0034] The structural diagrams of the components shown in the attached figures are exemplary. The specific implementation should be adapted and optimized by considering the functional requirements, assembly conditions and process limitations in the actual application scenario, and adjusting the structural parameters, size specifications and connection methods accordingly.

[0035] In use, this utility model works as follows: First, the power wrench is used to press the power clamp 612, causing the limiting clamp 614 to disengage from the limiting plate 615. Then, the power wrench is used to rotate the power clamp 612, causing the connecting clamp 611 to drive the worm gear 608 to rotate. The rotation of the worm gear 608 controls the slow rotation of the worm wheel 607, which in turn drives the spiral rod 606 to rotate. This causes the adjusting sleeve 605 to move the adjusting frame 604 up and down, moving the adjusting frame 604 to a suitable height. The lifting device 3 controls the composite box 4 to move downward, causing the composite box 4 to contact the limiting support rod 5. The motor 7 controls the rotation of the connecting sprocket 602. Through the transmission of the chain and the connecting sprocket 602, several thermodynamic rollers 601 rotate synchronously to transfer the two sets of metal foils. By controlling the distance between the rollers of the pressure roller group to gradually decrease, the metal foils are gradually heat-pressed, preventing excessive pressing at one time from causing damage to the aluminum and copper foils and improving the stability of the metal foil composite.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
