Description

Technical Field

[0001] This utility model belongs to the field of aluminum foil testing technology, specifically relating to an offline plate shape testing device. Background Technology

[0002] Battery foil is made of copper or aluminum and is one of the main raw materials used in the production of lithium batteries. The shape of the rolled sheet of battery foil is an important technical indicator that affects the quality of battery foil and the entire lithium battery product.

[0003] Currently, when offline shape measuring instruments perform shape detection on the surface of aluminum foil, the aluminum foil is usually wound around a guide roller, and then two tension control rollers are used to flatten the aluminum foil at the location to be tested for flatness detection. Depending on the different accuracy requirements, the distance between the two tension control rollers is usually 1m, 1.5m, or 2m. At present, the tension control rollers of offline shape measuring instruments are mostly fixed. By setting multiple tension control rollers, different accuracy detection requirements can be met. Therefore, when switching between different accuracy detection, it is necessary to cut the aluminum foil that has been tested, and then change the winding method of the unwound aluminum foil, so that the aluminum foil is wound between two tension control rollers with different distances to achieve different accuracy shape detection, which is quite troublesome. Summary of the Invention

[0004] This invention addresses the problem that existing offline flatness testing devices require cutting aluminum foil and changing the winding method of the aluminum foil to be tested when performing flatness tests of different precisions, which is very cumbersome. It provides an offline flatness testing device that, by setting a movable tension control roller, allows for direct adjustment of the tension control roller's position without changing the aluminum foil winding method when performing flatness tests of different precisions, thus making it easier to switch the effective testing distance.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: An offline sheet shape inspection device includes a frame and an inspection device, guide rollers, and two tension control rollers mounted on the frame. The inspection device is used to inspect and acquire sheet shape data. Tension control rollers are provided on both sides of the inspection device, and the positions of the tension control rollers on the frame are adjustable. Guide rollers are provided on the sides of the two tension control rollers that are far apart from each other. The two guide rollers are of the same height, and the two tension control rollers are of the same height. The height of the guide rollers is greater than the height of the tension control rollers. The movable tension control rollers avoid the problem of having to change the aluminum foil winding method when performing inspections with different accuracies.

[0006] Preferably, the offline sheet shape detection equipment further includes an unwinding device and a rewinding device, which are arranged opposite to each other at both ends of the frame for unwinding aluminum foil and rewinding aluminum foil after sheet shape detection.

[0007] Preferably, the detection device includes a support frame and a detection element that is slidably disposed on the support frame along the width direction of the frame, and the detection of different positions on the surface of the aluminum foil is achieved by driving the detection element to move.

[0008] Preferably, the detection component is a laser measuring instrument.

[0009] Preferably, each tension control roller is provided with an installation mechanism and a moving mechanism at both ends. The installation mechanism includes a bearing seat at the end of the tension control roller, and the tension control roller is connected to the bearing seat through a bearing. The moving mechanism includes a wheel frame and a wheel mounted on the wheel frame. The bearing seat is fixedly disposed above the wheel frame. Two parallel track grooves are opened on the upper side of the frame, and the lower part of the wheel is located in the corresponding track groove, which guides the movement direction of the wheel.

[0010] Preferably, the frame is provided with a limiting mechanism, which includes a driving mechanism, a connecting mechanism and multiple columns fixedly installed above the connecting mechanism, the driving mechanism being used to drive the connecting mechanism to rise and fall; each of the bottom of the track groove has a limiting hole that runs vertically through the frame, the width of the limiting hole along the extension direction of the track groove is smaller than the diameter of the wheel, and the upper end of each column is located in the corresponding limiting hole, so that the upper side of the multiple columns is flush with the bottom surface of the track groove by driving the multiple columns to rise and fall, so that the wheel can move.

[0011] Preferably, the bottom of the track groove is provided with a plurality of first through holes that penetrate the frame vertically. Each limiting hole has a first through hole symmetrically arranged on both sides. A horizontal plate is fixedly arranged on both sides of the wheel frame. A second through hole is provided on the horizontal plate. A pin is inserted into the second through hole. The lower end of the pin passes through the corresponding first through hole. The wheel is fixed by the pin, thereby fixing the position of the corresponding tension control roller.

[0012] Preferably, the column includes an upper column and a lower column. The upper column matches the limiting hole, and the length of the lower column is greater than the length of the limiting hole. The lower column limits the upward stroke of the upper column.

[0013] The beneficial effects of this utility model through the above technical solution are as follows: 1. This utility model uses adjustable tension control rollers on the frame. After performing aluminum foil shape detection with a certain accuracy and completing the required length detection, when another accuracy plate shape detection is required, the positions of the two tension control rollers (the distance between the two tension control rollers) can be directly adjusted, and the length of the completed detection part can be recorded. This is convenient and quick, and there is no need to rewind the aluminum foil after cutting.

[0014] 2. This utility model achieves movement within the track groove by rotating wheels, thereby driving the corresponding tension control roller to move. When it moves to the designated position, the tension control roller can be fixed simply by inserting a pin into the corresponding second or first through hole. When the tension control roller needs to be moved, the pin can be pulled out, which is convenient, quick and effective, further improving adjustment efficiency.

[0015] 3. This utility model sets a limiting hole. When the wheel moves to the position of the limiting hole, the bottom of the wheel falls into the limiting hole. The limiting hole limits the movement of the wheel, thereby ensuring that the corresponding second through hole is vertically aligned with the first through hole below it. This avoids the first through hole and the second through hole being misaligned, which would require frequent adjustments and affect work efficiency. When the wheel needs to move, multiple columns are driven to rise, and the upper side of the columns pushes the wheel out of the corresponding limiting hole. Attached Figure Description

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-4 As shown, this embodiment provides an offline plate shape inspection device, including a frame 1 and an inspection device 2, a guide roller 3, and two tension control rollers 4 disposed on the frame 1. The inspection device 2 is used to detect and acquire plate shape data. The inspection device 2 includes a support frame and an inspection component that is slidably disposed on the support frame along the width direction of the frame. The inspection component is a laser measuring instrument, that is, the flatness and other plate shape data of aluminum foil are detected by the laser measuring instrument to ensure product accuracy.

[0026] Tension control rollers 4 are provided on both sides of the detection device 2. The position of the tension control rollers 4 on the frame 1 is adjustable. By adjusting the position of the two tension control rollers 4, the flatness of the aluminum foil surface can be detected with different precision. Specifically, for example, the distance between the two tension control rollers 4 can be adjusted to 1m, 1.5m, 2m, etc.

[0027] Guide rollers 3 are provided on the opposite sides of the two tension control rollers 4. The two guide rollers 3 are at the same height, and the two tension control rollers 4 are at the same height. The height of the guide roller 3 is greater than the height of the tension control roller 4. The aluminum foil is wound over one of the guide rollers, then under both tension control rollers 4, and then over the other guide roller 3. The effective detection distance is the distance between the two tension control rollers 4.

[0028] The offline plate shape detection equipment also includes an unwinding device 5 and a winding device 6. The unwinding device 5 and the winding device 6 are arranged opposite each other at both ends of the frame 1. The unwinding device 5 and the winding device 6 can both adopt existing technologies, and their specific structures will not be described in detail in this utility model.

[0029] Each tension control roller 4 is provided with an installation mechanism and a moving mechanism at both ends. The installation mechanism includes a bearing seat 7 at the end of the tension control roller 4. The tension control roller 4 is connected to the bearing seat 7 through a bearing, thereby realizing the rotational installation of the tension control roller 4. The moving mechanism includes a wheel frame 8 and a wheel 9 mounted on the wheel frame 8. The bearing seat 7 is fixedly set above the wheel frame 8, and the wheel frame 8 supports and fixes the bearing seat 7. Two parallel track grooves 10 are opened on the upper side of the frame 1. The lower part of the wheel 9 is located in the corresponding track groove 10, and the movement of the wheel 9 is guided and limited by the track groove 10.

[0030] The frame 1 is provided with a limiting mechanism, which includes a driving mechanism 11, a connecting mechanism 12 and multiple columns 13 fixedly installed above the connecting mechanism 12. The driving mechanism 11 is used to drive the connecting mechanism 12 to rise and fall. The connecting mechanism 12 can adopt a plate structure or a bracket structure to ensure that the lower ends of multiple columns 13 are fixed at the same time, so as to drive multiple columns 13 to rise and fall synchronously.

[0031] In one possible implementation, the drive mechanism 11 includes a motor and a screw. The motor is fixedly mounted on the ground, and its output end is fixedly connected to the screw. The screw thread passes through the connecting mechanism 12. The motor drives the screw to rotate, thereby causing the connecting mechanism 12 to rise and fall.

[0032] The bottom of each track groove 10 is provided with a limiting hole 14 that penetrates the frame 1 vertically. The width of the limiting hole 14 along the extension direction of the track groove 10 is smaller than the diameter of the wheel 9. When the wheel 9 moves above the corresponding limiting hole 14, the bottom of the wheel 9 sinks into the corresponding limiting hole 14. Then, the wheel frame 8 is fixed to fix the position of the corresponding tension control roller 4. The upper end of each column 13 is located in the corresponding limiting hole 14. When the wheel 9 needs to move, the column 13 is driven to move and push the wheel 9 out of the corresponding limiting hole 14.

[0033] The bottom of the track groove 10 has multiple first through holes 15 that penetrate the frame 1 vertically. Each limiting hole 14 has a first through hole 15 symmetrically arranged on both sides. The wheel frame 8 has a horizontal plate 16 fixed on both sides. The horizontal plate 16 has a second through hole 17. A pin is inserted into the second through hole 17. The lower end of the pin passes through the corresponding first through hole 15. By aligning the corresponding first through hole 15 with the second through hole 17 vertically, the pin is inserted into the second through hole 17 and its lower end passes through the first through hole 15, thereby fixing the relative position of the wheel frame 8 and the frame 1.

[0034] The column 13 includes an upper column 131 and a lower column 132. The upper column 131 matches the limiting hole 14. The length of the lower column 132 is greater than the length of the limiting hole 14. When the column 13 is driven to move upward, when the upper end of the lower column 132 abuts against the lower side of the frame 1, the upper side of the upper column 131 is flush with the bottom surface of the inner side of the track groove 10. The lower column 132 limits the stroke of the column 13 as it rises.

[0035] When in use, first perform a certain precision aluminum foil shape detection (for example, the distance between the two tension control rollers 4 is 1.5m at this time). After the required length of aluminum foil has been detected, simply move the two tension control rollers 4 to perform another precision shape detection (for example, adjust the distance between the two tension control rollers 4 to 2m). The specific adjustment method is as follows: Start the drive mechanism 11, drive the connecting mechanism 12 and multiple columns 13 to move upward, so that the upper side of the upper column 131 is flush with the inner bottom surface of the track groove 10. Pull out the pin in the second through hole 17, move the tension control roller 4 directly to the upper part of the corresponding limit hole 14, start the drive mechanism 11 again, drive the connecting mechanism 12 and multiple columns 13 to move downward, so that the wheel 9 falls into the corresponding limit hole 14. Under the action of the limit hole 14, the second through hole 17 corresponds vertically to the first through holes 15 on both sides of the limit hole 14. Insert the pin into the second through hole 17 again, and under the action of gravity, the lower part of the pin enters the lower first through hole 15, thereby fixing the position of the tension control roller 4. Then, perform plate shape detection again.

[0036] As one possible implementation, the pin can be a bolt, with its lower end passing through the corresponding first through hole 15 and extending out below the frame 1, and then threadedly connected to a nut to further enhance the fixing effect.

Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
