Description

Technical Field

[0001] This utility model belongs to the field of carbon foil coating technology, specifically relating to a drying device after carbon foil coating production. Background Technology

[0002] Carbon foil coating, also known as carbon-coated aluminum foil, is a material that can extend the life of battery packs. Carbon-coated aluminum foil (conductive coating) comes in two types: water-based (aqueous system) and oil-based (organic solvent system). It can provide static conductivity, collect the micro-current of active materials, thereby significantly reducing the contact resistance between positive / negative electrode materials and current collectors, and improving the adhesion between them. It can reduce the amount of binder used. When spraying carbon foil coating onto workpieces, the workpieces need to be dried.

[0003] Existing drying equipment is inconvenient for multi-station drying operations, requiring drying, installation, and disassembly to be performed separately. This results in waiting times during the drying process and reduces drying efficiency. This issue is a problem that urgently needs to be addressed by those in the field. Utility Model Content

[0004] The purpose of this invention is to provide a drying device for carbon foil coating production, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a drying device for carbon foil coating production, comprising two support frames, a sealed box fixedly connected to the inner wall between the two support frames, two heaters symmetrically distributed around the horizontal plane on the surface of the sealed box, a drive motor fixedly connected to the side of the sealed box near one support frame, the output shaft of the drive motor fixedly connected to a drive shaft via a coupling, a movable disc fixedly connected to one end of the drive shaft, a limit block fixedly connected to the side of the movable disc away from the sealed box, a protruding rod eccentrically provided on the side of the movable disc near the limit block with a distance from the limit block, an opening structure provided on the side of the sealed box away from the two heaters, a support shaft movably connected to the inner wall of the opening structure of the sealed box, a movable block fixedly connected to the end of the support shaft near the movable disc, and a movable frame fixedly connected to the outer wall of the opening structure of the sealed box. The outer wall of the movable frame is provided with a first groove and a second groove. A fixed shaft is fixedly connected to the inner wall of the first groove, and a spiral spring is sleeved on the outer wall of the fixed shaft. A sealing plate is sleeved on the outer wall of the spiral spring. A lead screw is movably connected to the inner wall of the second groove, and a guide rod is fixedly connected to the inner wall of the second groove. Positioning blocks are movably connected to the outer walls of both the lead screw and the guide rod. This facilitates the rotation of the movable disc and the limiting block by the drive motor through the drive shaft. The movable disc drives the protrusion to rotate the movable block intermittently through the cooperation of the limiting block. This causes the movable block to rotate the movable frame intermittently by a certain angle through the support shaft. Subsequently, the movable frame drives several stations distributed at equal angles to enter the sealed box for drying work in turn, or slide out of the sealed box for disassembly and assembly in turn. This realizes the function of multi-station drying, which is beneficial to ensure that the installation and disassembly work is not affected during the drying process, thereby ensuring continuous drying and improving drying efficiency.

[0006] Preferably, the movable block is octagonal in shape when viewed from the front, and the four straight edges of the movable block are provided with connecting grooves. Specifically, the connecting grooves cooperate with the protruding rods, so that the protruding rods can effectively slide into the interior of the connecting grooves when rotating, thereby causing the protruding rods to drive the movable block to rotate intermittently at 90° through the connecting grooves.

[0007] Preferably, the four inclined sides of the movable block are distributed in an arc shape, and one arc-shaped structure of the movable block is located on the same axial center line as the limiting block. Specifically, an arc-shaped groove is provided on one side of the limiting block, and the arc-shaped groove cooperates with the four straight sides of the movable block. The arc-shaped groove and the protrusion are distributed at the same angle along the axial center line of the drive shaft, which facilitates the limitation of the movable block by the limiting block, so that the movable block will not rotate accidentally. When the protrusion slides into the connecting groove and drives the movable block to rotate, the limitation of the movable block can be released through the arc-shaped groove, thereby ensuring the effective rotation of the movable block.

[0008] Preferably, the movable frame consists of eight support rods distributed at equal intervals, and four first grooves and four second grooves are staggered on the eight support rods. Specifically, the distance of the first groove from the center of the support shaft is greater than the distance of the second groove from the center of the support shaft, thereby ensuring that the workpiece can be effectively slid into the interior of the sealed box for drying.

[0009] Preferably, the sealing plate is rotatably connected to the fixed shaft via a spiral spring, and one end of the sealing plate is convex. Specifically, the fixed shaft and the sealing plate are connected through each other, and the distance between the sealing plate and the inner wall of the first groove is greater than the distance between the inner wall of the sealing box and the inner wall of the first groove. This ensures that the sealing plate can be reset and rotated by the spiral spring, thereby facilitating the sealing of the opening of the sealing box by the sealing plate.

[0010] Preferably, both ends of the lead screw are provided with threads, and the threads at both ends of the lead screw are distributed in opposite directions. Specifically, the positioning blocks are symmetrically distributed at both ends of the lead screw, which facilitates the sliding of the positioning blocks at both ends in opposite directions when the lead screw rotates, thereby facilitating the positioning and clamping of the workpiece.

[0011] Preferably, the inner wall of the positioning block is fixedly connected with a nut and a linear bearing, and the positioning block is threadedly connected to the lead screw through the nut, and slidably connected to the guide rod through the linear bearing, thereby facilitating the guiding of the positioning block by the guide rod and ensuring the effective sliding of the positioning block.

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

[0013] By incorporating a support frame, sealing box, heater, drive motor, drive shaft, movable disc, limit block, protruding rod, support shaft, movable block, movable frame, fixed shaft, spiral spring, sealing plate, lead screw, guide rod, and positioning block, the system facilitates the sequential entry of workpieces positioned at different angles into the sealing box for drying. The dried workpieces then slide out of the sealing box for disassembly, thus achieving multi-station drying functionality. This ensures that the drying process does not interfere with installation and disassembly, guaranteeing continuous drying and improving drying efficiency. Attached Figure Description

[0019] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-3This utility model provides a technical solution: a drying device for carbon foil coating production, comprising two support frames 1, a sealed box 2 fixedly connected to the inner wall between the two support frames 1, two heaters 3 symmetrically distributed around the horizontal plane on the surface of the sealed box 2, a drive motor 4 fixedly connected to the side of the sealed box 2 near one of the support frames 1, the output shaft of the drive motor 4 fixedly connected to a drive shaft 5 via a coupling, a movable disc 6 fixedly connected to one end of the drive shaft 5, a limit block 7 fixedly connected to the side of the movable disc 6 away from the sealed box 2, a protruding rod 8 eccentrically provided on the side of the movable disc 6 near the limit block 7 with a distance from the limit block 7, an opening structure on the side of the sealed box 2 away from the two heaters 3, a support shaft 9 movably connected to the inner wall of the opening structure of the sealed box 2, a movable block 10 fixedly connected to the end of the support shaft 9 near the movable disc 6, and a movable frame 11 fixedly connected to the outer wall of the opening structure of the sealed box 2, the outer wall of the movable frame 11 having a first The first groove has a fixed shaft 12 fixedly connected to its inner wall, a spiral spring 13 sleeved on the outer wall of the fixed shaft 12, and a sealing plate 14 sleeved on the outer wall of the spiral spring 13. The second groove has a lead screw 15 movably connected to its inner wall, and a guide rod 16 fixedly connected to its inner wall. Both the lead screw 15 and the guide rod 16 have positioning blocks 17 movably connected to their outer walls. This allows the drive motor 4 to rotate the movable disc 6 and the limiting block 7 via the drive shaft 5, causing the movable disc 6 to drive the protruding rod 8 to rotate the movable block 10 intermittently through the limiting block 7. This causes the movable block 10 to drive the movable frame 11 to rotate intermittently by a certain angle via the support shaft 9. Consequently, the movable frame 11 drives several equally angled workstations to enter the sealed box 2 for drying work in turn, or to slide out of the sealed box 2 for disassembly and assembly in turn. This achieves the function of multi-workstation drying, which is beneficial because the drying process does not affect the installation and disassembly work, thus ensuring continuous drying and improving drying efficiency.

[0021] Preferably, the movable block 10 is arranged in an octagonal shape when viewed from the front, and the four straight edges of the movable block 10 are provided with connecting grooves. Specifically, the connecting grooves cooperate with the protruding rod 8, so that the protruding rod 8 can effectively slide into the interior of the connecting groove when rotating, thereby causing the protruding rod 8 to drive the movable block 10 to rotate intermittently at 90° through the connecting groove.

[0022] Preferably, the four inclined sides of the movable block 10 are distributed in an arc shape, and one arc structure of the movable block 10 is located on the same axial center line as the limiting block 7. Specifically, an arc groove is provided on one side of the limiting block 7, and the arc groove cooperates with the four straight sides of the movable block 10. The arc groove and the protruding rod 8 are distributed at the same angle along the axial center line of the drive shaft 5, which facilitates the restriction of the movable block 10 by the limiting block 7, so that the movable block 10 will not rotate accidentally. When the protruding rod 8 slides into the connecting groove and drives the movable block 10 to rotate, the limiting of the movable block 10 can be released through the arc groove, thereby ensuring the effective rotation of the movable block 10.

[0023] Preferably, the movable frame 11 consists of eight support rods that are evenly spaced, and the first groove and the second groove are respectively distributed in four staggered positions on the eight support rods. Specifically, the distance of the first groove from the center of the support shaft 9 is greater than the distance of the second groove from the center of the support shaft 9, thereby ensuring that the workpiece can be effectively slid into the interior of the sealed box 2 for drying.

[0024] Preferably, the sealing plate 14 is rotatably connected to the fixed shaft 12 via a spiral spring 13, and one end of the sealing plate 14 is convex. Specifically, the fixed shaft 12 and the sealing plate 14 are connected through each other, and the distance between the sealing plate 14 and the inner wall of the first groove is greater than the distance between the inner wall of the sealing box 2 and the inner wall of the first groove. This ensures that the sealing plate 14 can be reset and rotated by the spiral spring 13, thereby facilitating the sealing of the opening of the sealing box 2 by the sealing plate 14.

[0025] Preferably, both ends of the lead screw 15 are provided with threads, and the threads at both ends of the lead screw 15 are distributed in opposite directions. Specifically, the positioning blocks 17 are symmetrically distributed at both ends of the lead screw 15, which facilitates the sliding of the positioning blocks 17 at both ends in opposite directions when the lead screw 15 rotates, thereby facilitating the positioning and clamping of the workpiece.

[0026] Preferably, the inner wall of the positioning block 17 is fixedly connected with a nut and a linear bearing, and the positioning block 17 is threadedly connected to the lead screw 15 through the nut, and the positioning block 17 is slidably connected to the guide rod 16 through the linear bearing, thereby facilitating the guiding of the positioning block 17 by the guide rod 16 and ensuring the effective sliding of the positioning block 17.

[0027] In use, first start the drive motor 4, which drives the drive shaft 5 to rotate. The drive shaft 5 then drives the movable disc 6 and the limiting block 7 to rotate. The movable disc 6 drives the convex rod 8 to rotate, causing the convex rod 8 to slide into the connecting groove and drive the movable block 10 to rotate. As the limiting block 7 rotates, its arc-shaped groove gradually contacts the straight edge of the movable block 10, thus ensuring the effective rotation of the movable block 10. This achieves intermittent rotation of the movable block 10 at 90°. At this time, since the eight support rods of the movable frame 11 have four first grooves and two second grooves distributed at equal angles, the... The positioning block 17 inside the second groove can be used to press the workpiece in conjunction with the lead screw 15 and the guide rod 16. The sealing box 2 can be sealed by the elastic rotation of the sealing plate 14 driven by the spiral spring 13 inside the first groove. Then, when the movable block 10 drives the movable frame 11 to rotate intermittently through the support shaft 9, it can drive the workpieces at different angle positions to slide into the interior of the sealing box 2 for drying. It can also install and remove workpieces at positions that are not yet dried or have been dried, so that there is no need to wait during the drying process, which effectively improves the drying efficiency.
