Description

Technical Field

[0001] This invention relates to the field of coating technology, and in particular to a roll-up and unrolling clamping structure, a roll-up device, and a coating device. Background Technology

[0002] Coating refers to a method of applying a paste-like polymer, molten polymer, or polymer melt onto paper, cloth, or plastic film to produce a composite material (film). In battery coating scenarios, a roller-shaped roll structure is typically used to mount the film roll. One side of the roll structure usually has a clamping structure for holding the roller in place. This clamping structure is equipped with a drive mechanism that rotates the roll structure via the clamping structure. In actual production, workers mount the roll structure with the film roll onto the clamping structure, and then the drive mechanism rotates the roll structure, allowing the film roll to be conveyed downstream to the coating equipment. This enables the coating equipment to continuously coat the film roll.

[0003] like Figure 1 The existing chuck structure includes a mounting base 01, which is rotatably connected to a bushing 03 via two tapered roller bearings 02. Under the action of the tapered roller bearings, the bushing 03 can only rotate relative to the mounting base 01. A mandrel 04 is slidably connected to the inner cavity of the bushing 03. A keyway 05 is provided in the inner cavity of the bushing 03. The mandrel 04 is connected to a key unit 06, which can slide in the keyway 05. That is, the mandrel 04 is slidably connected to the bushing 03 via a key connection. At the same time, a chuck assembly 07 is connected to one end of the mandrel 04 that protrudes from the bushing 03. The chuck assembly 07 is used to clamp the coiled material roll 08.

[0004] The above-mentioned chuck structure has the following drawbacks: 1. During the sliding process of the chuck assembly 07, the load application point of the mandrel 04 changes continuously with the position of the chuck assembly 07, resulting in uneven load distribution. Therefore, the mandrel 04 requires high strength, which in turn increases the cost. 2. Since the size of the chuck assembly 07 is usually larger than the size of the mandrel 04, a concave area is formed between the chuck assembly 07 and the bushing 03. The width of this area changes with the movement of the mandrel 04, which poses a risk of hand pinching. That is, when installing the coil sleeve 08, the worker is easily pinched between the chuck assembly 07 and the mounting base 01, which is a safety hazard.

[0005] The existing clamping structure has the drawbacks of high cost and significant safety risks. Summary of the Invention

[0011] Optionally, a deep groove ball bearing and a tapered roller bearing are provided between the bushing portion and the clamping mandrel;

[0012] The inner ring of the deep groove ball bearing is fitted onto one end of the clamping mandrel, and the outer ring of the deep groove ball bearing is fitted into the bushing portion; the inner ring of the tapered roller bearing is fitted onto the other end of the clamping mandrel, and the outer ring of the tapered roller bearing is fitted into the bushing portion.

[0013] Optionally, a push connector is connected between the clamping mandrel and the drive end of the drive assembly;

[0014] The push connector includes an inner connecting part and an outer connecting part arranged from the inside to the outside. The inner connecting part is located on the side of the deep groove ball bearing away from the tapered roller bearing and is fixedly connected to the bushing part; the outer connecting part is fixedly connected to the drive assembly.

[0015] Optionally, the inner connecting part includes a clearance hole formed in the push connecting member, and the sleeve edge of the bushing part is provided with a threaded connection hole at the position corresponding to the clearance hole; the threaded connection hole is locked to the clearance hole by a bolt.

[0016] Optionally, the drive assembly includes a first translation assembly and a second translation assembly, and the bushing is disposed between the first translation assembly and the second translation assembly;

[0017] One end of the external connecting part is fixedly connected to the moving end of the first translation component, and the other end of the external connecting part is fixedly connected to the moving end of the second translation component. Both the fixed ends of the first translation component and the fixed ends of the second translation component are fixed to the clamping mounting part.

[0018] Optionally, the first translation component includes a cylinder unit fixedly connected to the clamping mounting portion, and the telescopic end of the cylinder unit is fixedly connected to one end of the external connecting portion.

[0019] A guide rail mounting plate is also connected to the fixed end of the cylinder unit, and a guide rail unit is mounted on the guide rail mounting plate. The external connecting part is slidably connected to the guide rail unit through a slider.

[0020] Optionally, the second translation component includes a lead screw mounting block fixedly connected to the clamping mounting portion;

[0021] The lead screw mounting block is threadedly connected to a lead screw unit. One end of the lead screw unit is fixedly connected to the other end of the external connecting part. A motor unit is provided on one side of the lead screw unit. A lead screw lifting unit is fixedly connected to the rotating shaft end of the motor unit.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] The winding and unwinding clamping structure, winding equipment, and coating equipment provided by this invention can drive the clamping mandrel to move via a drive component, thereby driving the chuck assembly to move, thus completing the clamping action of the chuck assembly on the winding roll. In this process, on the one hand, the connection between the clamping mandrel and the bushing is a rotational connection; therefore, the bushing moves with the clamping mandrel. For the clamping mandrel, during sliding, the relative position between the clamping mandrel and the bushing remains unchanged, so the load point does not change, avoiding the problem of inconsistent load point, thereby reducing the strength requirements of the clamping mandrel. Simultaneously, Lateral movement is limited by the sliding connection between the bushing and the mounting hole, eliminating the need for key units or other connecting structures on the clamping mandrel and avoiding the strength reduction caused by keyways on the clamping mandrel. On the other hand, since the drive assembly moves the clamping mandrel synchronously by pushing the bushing, the relative position between the bushing and the clamping mandrel remains unchanged. Furthermore, the bushing is installed in the first mounting hole and is convex in shape, eliminating the risk of pinching fingers and thus improving safety. In summary, the unwinding and winding clamping structure, winding equipment, and coating equipment of the present invention have the advantages of high strength and high safety.

[0043] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0044] Please refer to Figures 2 to 7 , Figure 2 This is a cross-sectional schematic diagram of the winding and unwinding clamping structure provided in an embodiment of the present invention. Figure 3 for Figure 2 A magnified schematic diagram of the structure at point A. Figure 4 for Figure 2 A magnified view of the structure at point B. Figure 5 This is a cross-sectional structural diagram of the clamping mounting part according to an embodiment of the present invention. Figure 6 This is a partial cross-sectional view of the winding and unwinding clamping structure provided in an embodiment of the present invention. Figure 7 This is a schematic diagram of the structure of the roll forming equipment provided in an embodiment of the present invention.

[0045] Example 1

[0046] The winding and unwinding clamping structure provided in this embodiment is applied to winding material processing scenarios such as battery coating loading and unloading, and plastic film processing. It can clamp the winding drum 08 so that an external motor can drive the winding drum 08 to rotate, so that the winding material on the winding drum 08 can be transported to downstream equipment. In this embodiment, by improving the winding and unwinding clamping structure, the mandrel strength requirement is reduced, thereby reducing costs and improving safety.

[0047] like Figure 2As shown, the winding and unwinding clamping structure of this embodiment includes a drive assembly 300 and a clamping mounting portion 100 with a first mounting hole 111. A bushing portion 400 is slidably connected to the clamping mounting portion 100 in the first mounting hole 111, and a clamping mandrel 200 is rotatably connected to the inner ring of the bushing portion 400. One end of the clamping mandrel 200 protruding from the bushing portion 400 is used to connect to a chuck assembly 07, and the other end of the clamping mandrel 200 is fixedly connected to the drive end of the drive assembly 300. The drive assembly 300 is used to drive the clamping mandrel 200 to translate. The chuck assembly 07 can clamp the winding drum 08. The structure of the chuck assembly 07 is not specifically limited; it can be a pneumatic pusher that moves from the inside to the outside to clamp the inner wall of the winding drum 08, or it can be a pneumatic gripper that grips the winding drum 08 from the outside to the inside.

[0048] Specifically, this winding and unwinding clamping structure uses a drive assembly 300 to move the clamping mandrel 200, which in turn moves the chuck assembly 07 to clamp the winding drum 08. During this process, the clamping mandrel 200 and the bushing 400 are rotatably connected. Therefore, the bushing 400 moves with the clamping mandrel 200. During this sliding process, the relative position of the clamping mandrel 200 and the bushing 400 remains unchanged, thus the load point does not change, avoiding the problem of an unstable load point. This reduces the strength requirements of the clamping mandrel 200 and consequently lowers its cost, achieving the desired balance while maintaining strength. The strength requirements of the clamping mandrel 200 are reduced. Simultaneously, the lateral movement is limited by the sliding connection between the bushing portion 400 and the first mounting hole 111, eliminating the need for key units or other connecting structures on the clamping mandrel 200 and avoiding the strength reduction caused by keyways on the clamping mandrel 200. Furthermore, since the drive assembly 300 moves the clamping mandrel 200 synchronously by pushing the bushing portion 400, the relative position of the bushing portion 400 and the clamping mandrel 200 remains unchanged. Since the bushing portion 400 is installed in the first mounting hole 111 and has a convex shape, the risk of pinching is eliminated, thereby improving safety. In summary, the winding and unwinding clamping structure of this embodiment has the advantages of high strength and high safety.

[0049] Furthermore, such as Figure 2 and Figure 6As shown, a deep groove ball bearing 510 and a tapered roller bearing 02 are disposed between the bushing portion 400 and the clamping mandrel 200. The inner ring of the deep groove ball bearing 510 is fitted onto one end of the clamping mandrel 200, and the outer ring of the deep groove ball bearing 510 is fitted into the bushing portion 400. The inner ring of the tapered roller bearing 02 is fitted onto the other end of the clamping mandrel 200, and the outer ring of the tapered roller bearing 02 is fitted into the bushing portion 400. In this embodiment, the tapered roller bearing 02 is a double-row tapered roller bearing. The combination of the deep groove ball bearing 510 and the double-row tapered roller bearing improves the load-bearing capacity of the winding and unwinding clamping structure.

[0050] Furthermore, such as Figure 2 and Figure 3 As shown, a push connector 600 connects the clamping mandrel 200 and the drive end of the drive assembly 300. The push connector 600 is sleeved on one end of the clamping mandrel 200. The push connector 600 includes an inner connecting part 601 and an outer connecting part 602 arranged from the inside to the outside. The inner connecting part 601 is located on the side of the deep groove ball bearing 510 away from the tapered roller bearing 02 and is fixedly connected to the bushing part 400. The outer connecting part 602 is fixedly connected to the drive assembly 300. The inner connecting part 601 is circular, and the outer connecting part 602 is rectangular and extends outward from the inner connecting part 601. Figure 1 As shown, in the conventional scheme, a push block 09 is sleeved on the mandrel 04 via a tapered roller bearing 02. Due to the influence of machining and assembly errors, the centerline of the push block 09 and the bushing 03 is difficult to coincide, which leads to the push block 09 applying radial load to the bushing 03. In this embodiment, the push connector 600 is directly connected to the bushing part 400, and the bushing part 400 can directly drive the clamping mandrel 200 to move. On the one hand, this avoids the clamping mandrel 200 from directly receiving radial load from the push connector 600, improving the overall rotational performance. On the other hand, this structure facilitates assembly and reduces the assembly requirements between the push connector 600, the bushing part 400, and the clamping mandrel 200.

[0051] In one specific implementation, such as Figure 3 As shown, the inner connecting part 601 includes a clearance hole formed in the push connector 600, and the sleeve part 400 has a threaded connection hole 401 at the position corresponding to the clearance hole on the edge of the sleeve opening; the threaded connection hole 401 is locked to the clearance hole by a bolt. In other optional embodiments, a positioning pin can be inserted at the edge of the sleeve part 400, and then the positioning hole of the inner connecting part 601 can be interference-fitted onto the positioning pin to complete the installation.

[0052] Furthermore, such as Figures 2 to 4As shown, the drive assembly 300 includes a first translation assembly 310 and a second translation assembly 320. A bushing portion 400 is disposed between the first translation assembly 310 and the second translation assembly 320. One end of the external connecting portion 602 is fixedly connected to the moving end of the first translation assembly 310, and the other end of the external connecting portion 602 is fixedly connected to the moving end of the second translation assembly 320. The fixed ends of both the first translation assembly 310 and the second translation assembly 320 are fixed to the clamping mounting portion 100. The arrangement of the two translation assemblies makes the movement of the bushing portion 400 smoother and more stable. Furthermore, in this embodiment, the translation assemblies, bushing portion 400, and clamping mandrel 200 are all mounted on the clamping mounting portion 100, thus improving overall stability and installation accuracy.

[0053] In this embodiment, as Figure 3 As shown, the first translation component 310 includes a cylinder unit 311 fixedly connected to the clamping mounting part 100. The telescopic end of the cylinder unit 311 is fixedly connected to one end of the external connecting part 602. A guide rail mounting plate 312 is also connected to the fixed end of the cylinder unit 311. A guide rail unit 313 is mounted on the guide rail mounting plate 312. The external connecting part 602 is slidably connected to the guide rail unit 313 through a slider.

[0054] like Figure 4 As shown, the second translation component 320 includes a lead screw mounting block 321 fixedly connected to the clamping mounting part 100; the lead screw mounting block 321 is threadedly connected to a lead screw unit 322, one end of the lead screw unit 322 is fixedly connected to the other end of the external connecting part 602, a motor unit 323 is provided on one side of the lead screw unit 322, and a lead screw lifting unit 324 is fixedly connected to the rotating shaft end of the motor unit 323. The lead screw lifting unit 324 is sleeved on the outside of the lead screw unit 322 and is used to drive the lead screw unit 322 to move. The lead screw lifting unit 324 can be a lead screw nut. When the motor unit 323 drives the lead screw lifting unit 324 to rotate, the lead screw unit 322 is restricted by the lead screw lifting unit 324 and performs a coupled rotational and translational movement; at the same time, a protective cover can be fitted onto the end of the lead screw unit 322 that protrudes from the clamping mounting part 100.

[0055] It should be noted that one of the translation components is powered by a cylinder, and the other is powered by a servo motor equipped with a lead screw. On the one hand, the cylinder can ensure sufficient axial force on the bushing 400, and on the other hand, the servo motor can ensure the motion accuracy of the bushing 400. At the same time, when the cylinder is returning, the servo motor can also increase its return speed.

[0056] In this embodiment, as Figure 5As shown, the clamping mounting part 100 includes a flip mounting base 110 and a flip support plate 120. The flip support plate 120 has a second mounting hole 121. The flip mounting base 110 passes through the second mounting hole 121, and the first mounting hole 111 is opened in the flip mounting base 110. The flip mounting base 110 has a keyway 112 at the hole wall of the first mounting hole 111. The bushing part 400 is fixedly connected to the flat key part 410, and the flat key part 410 is slidably connected to the keyway 112.

[0057] In summary, the winding and unwinding clamping structure of this embodiment has the advantages of high strength and high safety, as well as high precision and high stability.

[0058] Example 2

[0059] like Figure 7 As shown, the roll material equipment of this embodiment includes a take-up and untake-up clamping structure as in Embodiment 1. A roll material drum 08 is detachably mounted on the take-up and untake-up clamping structure. Specifically, the roll material drum 08 is mounted on the chuck assembly 07. The roll material equipment also includes a rotary drive structure connected to the clamping mandrel 200 to drive the roll material drum 08 to rotate, thereby conveying the roll material downstream. Embodiment 1 describes the specific structure and technical effects of the take-up and untake-up clamping structure, and the roll material equipment of this embodiment also possesses its technical effects.

[0060] In summary, the roll-to-roll equipment of this embodiment has the advantages of high strength and high safety, as well as high precision and high stability.

[0061] Example 3

[0062] The coating apparatus of this embodiment includes a coating section, one end of which is equipped with a roll-to-roll device as described in Embodiment 2. The coating section is a device capable of applying a coating to the portion of the rolled material after it has been unrolled. Embodiment 2 describes the specific structure and technical effects of the roll-to-roll device; the coating apparatus of this embodiment uses that structure and also possesses its technical effects.

[0063] In summary, the coating equipment of this embodiment has the advantages of high strength and high safety, as well as high precision and high stability.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
