Description

Technical Field

[0001] This utility model relates to a composite current collector heating roller device, belonging to the technical field of heating roller devices. Background Technology

[0002] Composite current collectors are functional materials with a metal-polymer-metal "sandwich" structure. Their preparation relies heavily on a continuous vacuum coating process, which requires the coordinated operation of a vacuum winding chamber and a vacuum coating chamber. The vacuum winding chamber, as a key component for continuous production and coating uniformity, integrates core components such as an unwinding / rewinding system, a tension control system, a flattening roller, a cooling roller, and plasma cleaning. The unwinding / rewinding system carries the raw material roll and the finished film roll; the tension control system maintains constant tension on the substrate to prevent wrinkling, stretching, or breakage; the flattening roller eliminates internal stress and wrinkles on the substrate; the cooling roller ensures dimensional stability of the substrate after heating and provides a uniform coating "base"; and plasma cleaning removes moisture and contaminants from the substrate surface, activates the surface, and improves coating adhesion.

[0003] In the actual manufacturing process of composite current collectors, wrinkles are a common and troublesome appearance defect. Their causes are complex, often resulting from the combined effects of multiple factors such as material quality and processing parameters. In existing technologies, the core method for eliminating wrinkles is to use a contact-type conductive heating roller. Heating causes the material to recover and recrystallize, releasing internal stress, improving ductility, and ensuring coordinated deformation during subsequent processing. However, this method has significant drawbacks: the composite current collector is directly attached to the surface of the heating roller. If foreign objects or stains are present, it will not only disrupt the heating and flattening effect, but hard particles may also scratch or even break the substrate or metal layer, leading to the scrapping of the entire roll of product. Existing cleaning methods rely on manual operation, requiring the heating roller to be stopped and cooled, which is time-consuming and affects production efficiency. Furthermore, cleaning requires manually pulling the composite current collector away from the heating roller, resulting in poor operational convenience. Utility Model Content

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A composite current collector heating roller device includes: a fixed frame, a connecting plate provided at the bottom of the fixed frame via a lifting assembly, a rotating shaft rotatably mounted at the middle of the connecting plate via a bearing, a rotating roller assembly provided at one end of the rotating shaft, a heating assembly provided inside the rotating roller assembly, a cleaning assembly for cleaning the rotating roller assembly provided on the connecting plate, and auxiliary mechanisms on both sides of the rotating roller assembly for moving the composite current collector away from the rotating roller assembly.

[0007] Preferably, the lifting assembly includes an electric cylinder, which is installed at the bottom of the fixed frame.

A limit telescopic rod is installed between the fixed frame and the connecting plate.

[0008] Preferably, the roller assembly includes two arc-shaped plates, both ends of which are detachably fitted with sealing caps, and one end of the sealing cap is fixedly installed at the center of the roller shaft.

[0009] Preferably, inserts are installed above one of the arc-shaped plates and below the other arc-shaped plate, and slots for inserting the inserts are provided below one of the arc-shaped plates and above the other arc-shaped plate.

[0010] Preferably, both ends of the arc-shaped plate are provided with arc-shaped threaded grooves that are threaded to the sealing cap.

[0011] Preferably, the heating assembly includes two sets of four heating rods, which are respectively installed on the inner walls of the two arc-shaped plates, and a temperature sensor is installed on the inner wall of one of the sealing covers.

[0012] Preferably, the cleaning assembly includes a multi-stage electric telescopic rod, which is installed below the connecting plate. The output end of the multi-stage electric telescopic rod is equipped with a movable ring concentric with the rotating shaft, and the inner wall of the movable ring is equipped with an annular cleaning cotton.

[0013] Preferably, the auxiliary mechanism includes two vertical slots, which are respectively opened on both sides of the connecting plate. A lead screw is rotatably installed on the vertical slot. An L-shaped lead screw seat is provided on the outer side wall of the lead screw through a thread. An auxiliary roller is rotatably installed on the L-shaped lead screw seat through an adjustment component.

[0014] Preferably, the adjustment assembly includes an electric push rod, which is installed on one side of the L-shaped wire seat. An adjustment block is installed at the output end of the electric push rod. A connecting shaft is rotatably installed at one end of the adjustment block.

[0015] Preferably, a timing pulley is installed at the bottom of the lead screw, and the two timing pulleys are driven by a timing belt.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. By setting up a cleaning component consisting of a multi-stage electric telescopic rod, a moving ring, and a ring-shaped cleaning cotton, automatic cleaning of the roller assembly can be achieved without cooling, which greatly shortens the cleaning time and improves production efficiency.

[0018] 2. The roller assembly consists of two arc-shaped plates connected by inserts and slots, with both ends sealed by sealing caps. The arc-shaped threaded grooves at both ends of the arc-shaped plates facilitate the installation and removal of the sealing caps.

The arc-shaped plates are heated by the heating assembly, and the heating rods are arranged at equal intervals along the circumference of the roller, which can ensure temperature control in all areas of the roller surface. This avoids melting of the polymer base film of the composite current collector due to local overheating, or incomplete wrinkle removal due to insufficient local heating, thus ensuring the wrinkle removal effect.

Detailed Implementation

[0026] 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.

[0027] Please see Figure 1-2 This utility model provides a technical solution:

[0028] A composite current collector heating roller device includes: a fixed frame 1, a connecting plate 3 provided at the bottom of the fixed frame 1 via a lifting component 2, a rotating shaft 4 rotatably mounted at the middle of the connecting plate 3 via a bearing, a rotating roller assembly 5 provided at one end of the rotating shaft 4, a heating component 6 provided on the rotating roller assembly 5, a cleaning component 7 for cleaning the rotating roller assembly 5 provided on the connecting plate 3, and auxiliary mechanisms 8 on both sides of the rotating roller assembly 5 for moving the composite current collector away from the rotating roller assembly 5.

[0029] Furthermore, a conductive slip ring is installed at the end of the rotating shaft 4 away from the rotating roller assembly 5, which enables the heating assembly 6 to work normally and avoids wire tangling.

[0030] Please see Figure 1 In this embodiment: the lifting assembly 2 includes an electric cylinder 201, which is installed at the bottom of the fixed frame 1. The output end of the electric cylinder 201 is connected to the top middle of the connecting plate 3 through a pressure sensor 202. A limit telescopic rod 203 is installed between the fixed frame 1 and the connecting plate 3.

[0031] Furthermore, in the lifting assembly 2, the electric cylinder 201 serves as the core driving component. It can drive the connecting plate 3 to move precisely in the vertical direction through the extension and retraction of the output end, thereby adjusting the contact pressure between the roller assembly 5 and the composite current collector. Excessive pressure can easily cause the material to stretch and deform, while insufficient pressure will reduce the heating conduction efficiency and affect the wrinkle removal effect. The pressure sensor 202 can collect the pressure data at the output end of the electric cylinder 201 in real time and feed the data back to the control system.

[0032] Please see Figure 3 In this embodiment: the roller assembly 5 includes two arc-shaped plates 501, and both ends of the two arc-shaped plates 501 are detachably equipped with sealing covers 502. One end of the sealing cover 502 is fixedly installed at the center of the circle and one end of the rotating shaft 4.

[0033] Furthermore, the two arc-shaped plates 501 are spliced ​​together to form the cylindrical body of the roller assembly 5. Compared with the traditional one-piece molded roller, the core advantage of the spliced ​​design is that it can be disassembled for maintenance. When the internal heating component 6 or temperature sensor 602 fails, it is not necessary to disassemble the entire roller. Only the arc-shaped plate 501 needs to be disassembled to expose the internal components, which greatly reduces the difficulty of maintenance.

[0034] Please see Figure 3 In this embodiment: insert strips 503 are installed above one arc plate 501 and below another arc plate 501, and slots 504 for inserting into the insert strips 503 are opened below one arc plate 501 and above another arc plate 501.

[0035] Furthermore, the insert 503 and the slot 504 adopt a precise design with a concave-convex fit. The cross-sectional dimensions of the insert 503 and the slot dimensions of the slot 504 are perfectly matched. During splicing, the two arc plates 501 can be quickly positioned to avoid circumferential misalignment after splicing and ensure the curvature of the roller surface.

[0036] Please see Figure 3 In this embodiment: both ends of the arc plate 501 are provided with arc-shaped threaded grooves 505.

[0037] Furthermore, the curvature of the arc-shaped threaded groove 505 is completely consistent with the curvature of the outer wall of the arc-shaped plate 501. Its inner wall is machined with high-precision threads, which can be precisely matched and threadedly connected with the threads on the edge of the sealing cover 502. When the sealing cover 502 is screwed into the arc-shaped threaded groove 505, it can apply pressure evenly along the arc direction of the arc-shaped plate 501, so that the sealing cover 502 and the two ends of the arc-shaped plate 501 fit tightly together, avoiding poor sealing due to uneven force.

[0038] Please see Figure 3In this embodiment: the heating assembly 6 includes two heating rods 601, which are respectively installed on the inner walls of two arc-shaped plates 501, and a temperature sensor 602 is installed on the inner wall of a sealing cover 502.

[0039] Furthermore, the four heating rods 601 in the heating assembly 6 are uniformly distributed. Two heating rods 601 are installed on the inner walls of the two arc-shaped plates 501, and the four heating rods 601 are arranged at equal intervals along the circumference of the roller. This ensures that the temperature difference between different areas on the surface of the roller is controlled within ±2℃, avoiding the melting of the polymer base film of the composite current collector due to local overheating, or incomplete wrinkle removal due to insufficient local heating. The temperature sensor 602 is installed at the center of the inner wall of the sealing cover 502. It can collect the average temperature inside the roller in real time and transmit the data to the temperature control system. When the temperature exceeds the set range, the system automatically adjusts the power of the heating rods 601 to achieve constant temperature heating.

[0040] Please see Figure 4 In this embodiment: the cleaning component 7 includes a multi-stage electric telescopic rod 701, which is installed below the connecting plate 3. The output end of the multi-stage electric telescopic rod 701 is equipped with a moving ring 702 concentric with the rotating shaft 4, and an annular cleaning cotton 703 is installed on the inner wall of the moving ring 702.

[0041] Furthermore, the multi-stage electric telescopic rod 701 in the cleaning component 7 adopts a telescopic segmented structure, and its maximum telescopic length matches the axial length of the roller assembly 5. It can drive the moving ring 702 to completely cover the roller surface along the roller axis, avoiding cleaning dead corners. The concentric design of the moving ring 702 and the rotating shaft 4 can ensure that the contact pressure between the ring cleaning cotton 703 and the roller surface is uniform, preventing excessive local pressure from wearing the roller surface or insufficient pressure from causing incomplete cleaning. The ring cleaning cotton 703 is made of high-temperature resistant and highly absorbent composite fiber material, which can not only adapt to the working temperature of the roller, but also effectively absorb dust, metal particles and other foreign objects on the surface. The cleaning cotton 703 is connected to the moving ring 702 by Velcro, which can be disassembled and replaced regularly to avoid the accumulation of foreign objects affecting the cleaning effect.

[0042] Please see Figure 1 In this embodiment: the auxiliary mechanism 8 includes two vertical grooves 801, which are respectively opened on both sides of the connecting plate 3. A lead screw 802 is rotatably installed on the vertical groove 801. An L-shaped lead screw seat 803 is provided on the outer side wall of the lead screw 802 through a thread. An auxiliary roller 805 is rotatably installed on the L-shaped lead screw seat 803 through an adjusting component 804.

[0043] Furthermore, during the heating stage, two flattening rollers are installed on both sides above the arc plate 501, rotating and mounted on the side walls of the vacuum winding chamber. After the lifting assembly 2 drives the rotating roller assembly 5 to descend, the current collector is conveyed in a "V" shape. During the cleaning stage, the auxiliary roller 805 descends to press down on the composite current collector, while the lifting assembly 2 drives the rotating roller assembly 5 to rise. Finally, the auxiliary roller 805 moves to the bottom of the rotating roller assembly 5 to provide tension for the composite current collector, and the composite current collector detaches from the bottom of the rotating roller assembly 5 to form a cleaning gap.

[0044] Please see Figure 5 In this embodiment: the adjusting assembly 804 includes an electric push rod 8041, which is installed on one side of the L-shaped wire seat 803. An adjusting block 8042 is installed at the output end of the electric push rod 8041. A connecting shaft 8043 is rotatably installed at one end of the adjusting block 8042. One end of the connecting shaft 8043 and one end of the auxiliary roller 805 are fixedly installed. A slide rod 8044, which is fixedly installed with the adjusting block 8042, is slidably installed on the L-shaped wire seat 803.

[0045] Furthermore, during the heating stage, the electric push rod 8041 pushes the auxiliary roller 805 closer to the rotating roller assembly 5 to prevent the auxiliary roller 805 from contacting the composite current collector, thereby reducing the contact area between the composite current collector and the rotating roller and ensuring the heating effect. When cleaning the surface of the arc plate 501, the electric push rod 8041 drives the auxiliary roller 805 to retract, moving the auxiliary roller 805 away from the arc plate 501. At the same time, the auxiliary roller 805 descends, and the lifting assembly 2 rises synchronously, moving the composite current collector away from both sides of the arc plate 501. In this way, the descent of the auxiliary roller 805 can expand the lateral distance between the composite current collector on both sides of the arc plate 501 and the arc plate 501, avoiding contact between the moving ring 702 and the composite current collector on both sides of the arc plate 501, so that the cleaning operation can proceed smoothly.

[0046] Please see Figure 1 In this embodiment: a synchronous pulley 806 is installed at the bottom of the lead screw 802, and the two synchronous pulleys 806 are driven by a synchronous belt 807.

[0047] Furthermore, the synchronous pulley 806 is made of high-strength aluminum alloy, and its teeth precisely mesh with the tooth grooves of the synchronous belt 807. The top of a lead screw 802 is connected to a servo motor, which is mounted on the top of the connecting plate 3.

[0048] The workflow of this embodiment is as follows: The fixing frame 1 is installed on the side wall of the vacuum winding chamber. Before winding, the composite current collector passes through the bottom of the arc plate 501. After the heating rod 601 heats the arc plate 501, the arc plate 501 can heat the composite current collector and remove wrinkles. A conductive slip ring is installed at the end of the rotating shaft 4 away from the arc plate 501. The heating rod 601 and the conductive slip ring are electrically connected. The rotation of the arc plate 501 drives the rotation of the heating rod 601. The conductive slip ring can prevent the wire from tangling. Two flattening rollers are mounted on the upper sides of plate 501, rotating with the side walls of the vacuum winding chamber. This causes the current collector to be conveyed in a "V" shape. After passing the top of one flattening roller, the current collector passes the bottom of the curved plate 501, and then the top of the other flattening roller. The flattening roller on one side is for the first pre-flattening of the composite current collector film before it enters the curved plate 501, reducing wrinkles on the film surface and allowing the film surface to be as flat as possible before entering the curved plate 501 for heating. The function of the other flattening roller is... The process involves a secondary flattening of the recrystallized substrate after heating to maintain its optimal recrystallized state. During the heating phase, the electric push rod 8041 pushes the auxiliary roller 805 closer to the rotating roller assembly 5, preventing the auxiliary roller 805 from contacting the composite current collector and thus reducing the contact area between the composite current collector and the rotating roller, ensuring heating efficiency. When cleaning the surface of the curved plate 501, the electric push rod 8041 drives the auxiliary roller 805 to retract, moving the auxiliary roller 805 away from the curved plate 501. Simultaneously, the auxiliary roller 805 descends, and the lifting assembly... 2. The rollers rise synchronously, moving the composite current collector away from the sides of the arc plate 501. This allows the auxiliary roller 805 to descend, increasing the lateral distance between the composite current collector and the arc plate 501, preventing the moving ring 702 from contacting the composite current collector on both sides of the arc plate 501, thus ensuring smooth cleaning operations. Then, the multi-stage electric telescopic rod 701 extends the moving ring 702, allowing the annular cleaning cotton 703 to contact the arc plate 501 and wipe the surface of the arc plate 501. The electric cylinder 201 drives the connecting plate 3 to rise and fall, adjusting the tension of the composite current collector. The tension value can be adjusted via the pressure sensor 202. When maintenance of the heating rod 601 is required, the sealing cover 502 can be rotated to separate it from the arc plate 501, thus separating the two arc plates 501 and exposing the heating rod 601 and temperature sensor 602 for easy maintenance.
