Description

Technical Field

[0001] This utility model discloses a stretching device for producing composite current collectors, belonging to the field of current collector production technology. Background Technology

[0002] Composite current collectors are composite materials made by depositing copper / aluminum molecules on both sides of plastic films such as PET / PI / PP through processes such as vacuum coating. Compared with traditional current collectors, composite current collectors have advantages such as high safety, high energy density, low cost, long life and strong compatibility.

[0003] Currently, in the production process of composite current collectors, they need to be stretched to improve their tensile strength and elongation. During the stretching process, the composite current collector is usually heated to different temperatures and stretched multiple times. However, existing stretching devices can only process the same part of the composite current collector at the same time, and the same part needs to be processed multiple times, which results in slow processing and low production efficiency.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] The purpose of this invention is to provide a stretching device for producing composite current collectors in order to solve the above-mentioned problems, which has the effect of simultaneously stretching the composite current collector in multiple segments.

[0006] This utility model achieves the above-mentioned objectives through the following technical solution: It includes a housing, with an inlet and an outlet at its left and right ends respectively; guide roller sets are provided on the inner side of the housing corresponding to the inlet and outlet positions; a plurality of stretching rollers are provided in the middle of the inner side of the housing, with the stretching rollers arranged at equal intervals and staggered vertically; guide wheels are provided on the left and right sides of the stretching rollers on the inner side of the housing; clamping mechanisms are provided between the guide wheels and the guide roller sets on the housing; a plurality of stretching guide rails are provided at the front and rear ends of the inner side of the housing corresponding to the stretching roller positions; the front and rear ends of the stretching rollers are respectively mounted on the stretching guide rails; the housing is provided with a first drive source group for driving the stretching rollers to move up and down on the stretching guide rails; and heating coils are provided inside each of the stretching rollers.

[0007] By adopting the above technical solution, the composite current collector enters the inner side of the housing from the feed port on the left side of the housing. Guided by the guide roller group at the feed port, it passes through the center of the left clamping mechanism and extends to the left guide wheel. Guided by the left guide wheel, it alternately passes around several stretching rollers, and then passes through the center of the right clamping mechanism under the guidance of the right guide wheel. It extends to the guide roller group at the discharge port and is finally transported to the outside of the housing. The heating coil can heat the stretching rollers to different temperatures, thereby heating the composite current collector wound on the stretching rollers. The setting of the first drive source group and the stretching guide rail allows the composite current collector to be stretched in multiple segments and at multiple temperatures after being clamped and fixed by the two clamping mechanisms on both sides. This is achieved by heating the composite current collector on both sides simultaneously by the stretching rollers and then moving it up and down, effectively improving the processing efficiency.

[0008] Preferably, the housing is provided with baffles between two adjacent stretching rollers on the same horizontal line.

[0009] By adopting the above technical solution and setting the baffle, temperature conduction between two adjacent stretching rollers after heating can be avoided, thus ensuring the accuracy and stability of the heating temperature between several stretching rollers.

[0010] Preferably, both clamping mechanisms include two clamping blocks and two clamping guide rails. The two clamping guide rails are located at the rear end of the inner side of the housing and are horizontally mirrored. The two clamping blocks are respectively disposed on the two clamping guide rails and can move up and down on the two clamping guide rails respectively. The housing is provided with a second drive source group for driving the clamping blocks to move.

[0011] By adopting the above technical solution, when it is necessary to use the clamping mechanism to clamp and fix the left and right ends of the composite current collector, the second drive source group drives the two clamping blocks to move towards each other, which can fix the composite current collector passing between the two clamping blocks. To release the fixation, the two clamping blocks can be separated.

[0012] Preferably, the opposite ends of the two clamping blocks are covered with nitrile rubber.

[0013] By adopting the above technical solution, nitrile rubber has a high coefficient of friction, which can ensure the stability of clamping, while avoiding metal contact damage to copper foil and aluminum foil layers.

[0014] Preferably, a ventilation fan is provided at the upper end of the housing.

[0015] By adopting the above technical solutions, the ventilation fan can promptly remove volatile substances generated during the heating process or regulate the temperature inside the chamber, maintaining a stable processing environment and extending the service life of the equipment.

[0016] Preferably, both the first drive source group and the second drive source group consist of several servo motors.

[0017] By adopting the above technical solution, using servo motors as the power source for the first and second drive source groups, precise motion control of the stretching roller and clamping mechanism is achieved, reducing manual intervention, lowering operational errors, and improving production continuity and efficiency.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] Firstly, by setting up heating coils, stretching guides and clamping mechanisms, the device can simultaneously perform multi-temperature and multi-segment stretching processing on composite current collectors, which not only improves the processing efficiency of composite current collectors but also ensures the stretching quality, making the performance of composite current collectors more uniform and consistent.

[0020] Secondly, the clamping mechanism uses a movable clamping block, which, together with the nitrile rubber-coated surface, can not only firmly fix the end of the material, but also avoid scratching or damaging the material surface during the clamping process. It is especially suitable for high-precision or surface-sensitive composite current collectors.

[0021] Third, by setting baffles between different stretching rollers, temperature insulation can be achieved between adjacent stretching rollers, effectively avoiding temperature interference between stretching rollers and improving the dimensional accuracy and mechanical properties of the product.

[0022] Fourth, through the ventilation fan and the sealed design of the housing, the temperature and humidity of the processing environment and the emission of pollutants are effectively managed, which meets environmental protection requirements and reduces the impact of the external environment on the high-precision processing.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the present utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0027] A stretching device for producing composite current collectors, such as Figures 1-2 As shown, the device includes a housing 1, with an inlet 2 and an outlet 3 at its left and right ends, respectively. Guide roller sets 4 are installed on the inner side of the housing 1 corresponding to the inlet 2 and outlet 3. Several stretching rollers 5 are arranged in the middle of the inner side of the housing 1, with the stretching rollers 5 staggered and evenly spaced. Guide wheels 6 are installed on the left and right sides of the stretching rollers 5 on the inner side of the housing 1. Clamping mechanisms are installed between the guide wheels 6 and the guide roller sets 4. The composite current collector enters the inner side of the housing 1 from the inlet 2 on the left side. Guided by the guide roller sets 4 at the inlet 2, it passes through the center of the left clamping mechanism and extends towards the left guide wheel 6. Guided by the left guide wheel 6, it alternately passes around the stretching rollers 5, and then, guided by the right guide wheel 6, passes through the center of the right clamping mechanism and extends towards the guide roller sets 4 at the outlet 3. The material is then transferred to the outside of the housing 1. Several stretching guide rails 7 are installed at the front and rear ends of the inner side of the housing 1, corresponding to the positions of several stretching rollers 5. The stretching rollers 5 are respectively positioned on the stretching guide rails 7 at their front and rear ends. The housing 1 is equipped with a first drive source group that drives the stretching rollers 5 to move up and down on the stretching guide rails 7. Each stretching roller 5 has a heating coil inside, which heats the rollers 5 to different temperatures, thereby heating the composite current collector wound on the rollers 5. The arrangement of the first drive source group and the stretching guide rails 7 allows the composite current collector to be stretched in multiple segments at multiple temperatures after being clamped and fixed by two clamping mechanisms, and then moved up and down by the simultaneous heating of the stretching rollers 5. This effectively improves processing efficiency.

[0028] The housing 1 is equipped with baffles 8 between two adjacent stretching rollers 5 on the same horizontal line. The baffles 8 prevent heat conduction between the two adjacent stretching rollers 5 after heating, ensuring the accuracy and stability of the heating temperature between the stretching rollers 5. Both clamping mechanisms include two clamping blocks 9 and two clamping guide rails 10. The two clamping guide rails 10 are located at the rear end of the inner side of the housing 1 and are horizontally mirrored. The two clamping blocks 9 are respectively set on the two clamping guide rails 10. The two clamping blocks 9 can move up and down on the two clamping guide rails 10 respectively. The housing 1 is equipped with a second drive source group to drive the clamping blocks 9 to move. When it is necessary to use the clamping mechanism to clamp and fix the left and right ends of the composite current collector, the second drive source group drives the two clamping blocks 9 to move towards each other, thereby fixing the composite current collector passing between the two clamping blocks 9. To release the fixation, the two clamping blocks 9 are driven to separate.

[0029] Both clamping blocks 9 have their opposing ends covered with nitrile rubber. The nitrile rubber has a high coefficient of friction, which ensures the stability of the clamping and avoids metal-to-metal contact damage to the copper and aluminum foil layers. A ventilation fan 11 is installed at the top of the housing 1. The ventilation fan 11 can promptly remove volatile substances generated during the heating process or regulate the temperature inside the housing, maintain a stable processing environment, and extend the service life of the equipment. The first and second drive source groups are both composed of several servo motors. Using servo motors as the power source for the first and second drive source groups enables precise motion control of the stretching roller 5 and the clamping mechanism, reduces manual intervention, lowers operational errors, and improves production continuity and efficiency.

[0030] When performing multi-segment stretching processing on composite current collectors, the composite current collector to be processed is transferred from the feed port 2 on the left side of the housing 1 to the inside of the housing 1. After passing around the guide roller group 4 on the left side and passing through the clamping mechanism, it passes around the guide wheel 6 on the left side and is alternately wound on several stretching rollers 5. Then, it passes around the guide wheel 6 on the right side and passes through the clamping mechanism on the right side. Finally, it is transferred outward from the discharge port 3 under the guidance of the guide roller group 4 on the discharge port 3. Then, the second drive source group drives the clamping block 9 to fix the composite current collector. After the heating coil heats the stretching rollers 5, it controls several stretching rollers 5 to move under the drive of the first drive source to stretch the composite current collector. After the stretching is completed, the clamping mechanism releases the fixation of the composite current collector, and the composite current collector moves while several stretching rollers 5 are gradually reset. Then, the composite current collector at the next position is stretched. This device effectively improves the processing efficiency of composite current collector stretching processing.
