Description

Technical Field

[0001] This utility model relates to the field of lithium battery production technology, and in particular to a material unloading device for lithium battery production. Background Technology

[0002] With the global energy and environmental situation becoming increasingly tense, batteries are gaining popularity as a power source. Lithium-ion batteries, due to their high energy density, small size, light weight, environmental friendliness, and lack of memory effect, are gradually becoming the preferred choice in the energy sector.

[0003] The electrodes of lithium batteries undergo repeated winding and unloading processes during coating, rolling, slitting, and winding. The existing unloading process is cumbersome, wastes manpower and resources, and has low production efficiency.

[0004] Extensive research revealed that existing technologies, such as the application number CN202021726977.9, which describes a coil unloading device for lithium battery production, can unload coils used in lithium battery production, reducing labor costs. However, this technical solution can only be used for battery coils of the same width and specifications, limiting its application scope. Therefore, further improvements are needed.

[0005] Therefore, it is necessary to provide unloading devices for lithium battery production to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model provides an unloading device for lithium battery production, which solves the problems in the background art.

[0007] To solve the above-mentioned technical problems, the present invention provides a lithium battery production unloading device, comprising a device body, a limiting groove formed on the surface of the device body, a bidirectional lead screw movably mounted inside the limiting groove, a first support plate and a second support plate helically connected to the surface of the bidirectional lead screw, threaded holes through the surfaces of the first and second support plates, a drive cylinder vertically mounted on the top surface of the first and second support plates, a top plate provided at the output end of the drive cylinder, and an arc-shaped support seat vertically mounted on the top surface of the top plate. The bidirectional lead screw is driven by a stepper motor. The device comprises a limiting groove, a first support plate, a second support plate, threaded holes, a bidirectional lead screw, and a drive cylinder. The combined use of the top plate and the arc-shaped support seat facilitates the lifting and unloading of lithium battery rolls of different lengths. During operation, the operator first determines the width of the lithium battery roll, then starts the stepper motor. The stepper motor then drives the bidirectional lead screw to rotate, which in turn moves the first and second support plates to adjust the distance between them. After adjustment, the arc-shaped support seat is moved to below the winding shafts at both ends of the lithium battery roll by moving the main body of the device. Finally, the top plate and the arc-shaped support seat are lifted by the drive cylinder, thus completing the unloading of the lithium battery roll. This method is simple to operate and greatly improves its flexibility.

[0008] Preferably, a support cylinder is vertically mounted on the top surface of the first and second support plates. A support rod is slidably inserted into the support cylinder. An adjustment hole is formed through the surface of the support rod, and a fixing hole is formed on the surface of the support cylinder. The support rod is fixedly connected to the support cylinder via a connecting rod. The top of the support rod is fixed to the bottom surface of the top plate. By using the support cylinder, support rod, adjustment hole, fixing hole, and connecting rod in combination, the support performance of the top plate is improved. When the drive cylinder moves the top plate and the arc-shaped support seat to support the lithium battery coil, the top plate moves the support rod upward. When the lithium battery coil is lifted and disengaged from the connecting shaft, a fine adjustment is made to align the fixing hole with the adjustment hole. Then, the connecting rod passes through the fixing hole and the adjustment hole to fix the support rod and the support cylinder. This method is simple to operate and facilitates the improvement of the overall support performance of the top plate.

[0009] Preferably, the first support plate and the second support plate are provided with limiting cylinders on their sides, and limiting rods are slidably inserted into the limiting cylinders. The other ends of the two limiting rods are respectively fixed to the sides of the first support plate and the second support plate on opposite sides. By using the limiting cylinders and limiting rods in combination, the stability of the first support plate and the second support plate when moving is facilitated.

[0010] Preferably, multiple adjustment holes are provided, and the multiple adjustment holes are equally spaced on the surface of the support rod. By providing multiple adjustment holes, it is convenient to adjust the position of the support rod in multiple positions, thereby improving its flexibility of use.

[0011] Preferably, the thickness of the first support plate and the second support plate is equal to the inner width of the limiting groove. By setting the thickness of the first support plate and the second support plate to be equal to the inner width of the limiting groove, it is easy to ensure that the first support plate and the second support plate can move left and right inside the limiting groove.

[0012] Preferably, a push handle is provided on the outer surface of the device body, a first pulley is provided at the bottom end of the device body, and a second pulley is provided on the bottom end surface of the first support plate and the second support plate. By using the push handle, the first pulley and the second pulley in combination, the movement of the device body is facilitated, thereby facilitating the operation of the lithium battery raw material roll.

[0013] Preferably, a controller is installed on the outer surface of the device body, which facilitates the control of the electrical components inside the device body.

[0014] Compared with related technologies, the unloading device for lithium battery production provided by this utility model has the following advantages:

[0015] 1. Compared with existing technologies, the unloading device for lithium battery production, through the coordinated use of a limiting groove, a first support plate, a second support plate, threaded holes, a bidirectional lead screw, a drive cylinder, a top plate, and an arc-shaped support seat, facilitates the lifting and unloading of lithium battery coils of different lengths. During operation, the operator first determines the width of the lithium battery coil, then starts a stepper motor. The stepper motor then drives the bidirectional lead screw to rotate, thereby moving the first and second support plates to adjust the distance between them. After adjustment, the arc-shaped support seat is moved to below the winding shafts at both ends of the lithium battery coil by moving the device body. Then, the top plate and the arc-shaped support base are lifted by the drive cylinder, thus completing the unloading of the lithium battery coil. This method is simple to operate and greatly improves its flexibility. By setting up the support cylinder, support rod, adjustment hole, fixing hole and plug rod in cooperation, the support performance of the top plate is improved. When the drive cylinder drives the top plate and the arc-shaped support base to support the lithium battery coil, the top plate drives the support rod to move upward. When the lithium battery coil is lifted and disengaged from the connecting shaft, a fine adjustment is made to align the fixing hole and the adjustment hole. Then, the plug rod is inserted through the fixing hole and the adjustment hole to fix the support rod and the support cylinder. This method is simple to operate and improves the overall support performance of the top plate.

A bidirectional lead screw 16 is movably installed inside the limiting groove 12. A first support plate 4 and a second support plate 13 are helically connected to the surface of the bidirectional lead screw 16. Threaded holes are formed through the surfaces of the first support plate 4 and the second support plate 13. A drive cylinder 6 is vertically mounted on the top surface of the first support plate 4 and the second support plate 13. A top plate 7 is provided at the output end of the drive cylinder 6. An arc-shaped support seat 8 is vertically mounted on the top surface of the top plate 7. The bidirectional lead screw 16 is driven by a stepper motor 10. The device comprises the limiting groove 12, the first support plate 4, the second support plate 13, the threaded holes, the bidirectional lead screw 16, the drive cylinder 6, and the top plate. 7. The use of the arc-shaped support base 8 facilitates the lifting and unloading of lithium battery rolls of different lengths. During operation, the operator first determines the width of the lithium battery roll, then starts the stepper motor 10. The stepper motor 10 then drives the bidirectional lead screw 16 to rotate, thereby moving the first support plate 4 and the second support plate 13 to adjust the distance between them. After adjustment, the arc-shaped support base 8 is moved to below the winding shafts at both ends of the lithium battery roll by moving the device body 1. Finally, the top plate 7 and the arc-shaped support base 8 are lifted by the drive cylinder 6, thus completing the unloading of the lithium battery roll. This method is simple to operate and greatly improves its flexibility.

[0025] The working principle of the unloading device for lithium battery production provided by this utility model is as follows:

[0026] In the lithium battery production unloading device, the operator first starts the stepper motor 10 according to the width of the lithium battery roll. The stepper motor 10 then drives the bidirectional lead screw 16 to rotate, thereby moving the first support plate 4 and the second support plate 13 to adjust the distance between them. After adjustment, the arc-shaped support seat 8 is moved to below the winding shafts at both ends of the lithium battery roll by moving the device body 1. Finally, the top plate 7 and the arc-shaped support seat 8 are lifted by the drive cylinder 6, thus completing the unloading of the lithium battery roll. This method is simple to operate and greatly improves efficiency. To improve its flexibility of use, the support cylinder 5, support rod 19, adjustment hole 20, fixing hole 18, and plug rod 17 are used in combination to improve the support performance of the top plate 7. When the drive cylinder 6 drives the top plate 7 and the arc-shaped support seat 8 to support the lithium battery coil, the top plate 7 drives the support rod 19 to move upward. When the lithium battery coil is lifted and disengaged from the connecting shaft, a fine adjustment is made to align the fixing hole 18 with the adjustment hole 20. Then, the plug rod 17 passes through the fixing hole 18 and the adjustment hole 20 to fix the support rod 19 and the support cylinder 5. This method is simple to operate and facilitates the improvement of the overall support performance of the top plate 7.

[0027] Compared with related technologies, the unloading device for lithium battery production provided by this utility model has the following advantages:

[0028] The unloading device for lithium battery production, through the coordinated use of a limiting groove 12, a first support plate 4, a second support plate 13, a threaded hole, a bidirectional lead screw 16, a drive cylinder 6, a top plate 7, and an arc-shaped support seat 8, facilitates the lifting and unloading of lithium battery coils of different specifications and lengths. During operation, the operator first determines the width of the lithium battery coil, then starts the stepper motor 10. The stepper motor 10 then drives the bidirectional lead screw 16 to rotate, thereby moving the first support plate 4 and the second support plate 13 to adjust the distance between them. After adjustment, the arc-shaped support seat 8 is moved to below the winding shafts at both ends of the lithium battery coil by moving the device body 1. Finally, the drive cylinder 6... The top plate 7 and the arc-shaped support seat 8 are used to lift the lithium battery coil, thus completing the unloading of the lithium battery coil.

When the lithium battery coil is lifted and disengaged from the connecting shaft, a fine adjustment is made to align the fixing hole 18 with the adjustment hole 20. Then, the plug rod 17 passes through the fixing hole 18 and the adjustment hole 20 to fix the support rod 19 and the support cylinder 5. This method is simple to operate and improves the overall support performance of the top plate 7. Example
