Technical Field

[0001] This utility model relates to the technical field of lithium battery production, and specifically to a lithium battery separator docking and conveying device. Background Technology

[0002] The performance of the separator determines the battery's interface structure, internal resistance, etc., and directly affects the battery's capacity, cycle life, and safety performance. A high-performance separator plays an important role in improving the overall performance of the battery. The main function of the separator is to separate the positive and negative electrodes of the battery to prevent the two electrodes from contacting and short-circuiting.

[0003] Existing lithium battery separator processing equipment does not have the function of tension adjustment. Because lithium battery separators are long, it is difficult to adjust the tension of the separators, resulting in inconsistent quality of the separators. Furthermore, the unloading and replacement of separator rollers requires the assistance of multiple people, increasing the time and labor required for replacement. Utility Model Content

[0004] The purpose of this invention is to provide a lithium battery separator docking and conveying device to solve the above-mentioned defects caused by the prior art.

Flanges are provided on both sides of the separator roller. An unloading mechanism is provided directly below the separator roller. The unloading mechanism lifts the bottom of the separator roller by raising and lowering itself, thereby saving the time required for unloading the separator roller. A conveying mechanism is provided on one side of the separator roller. The conveying mechanism dynamically adjusts its own height according to the height of the separator roller, thereby ensuring the tension of the separator during conveying and preventing the membrane from loosening.

[0006] Preferably, the conveying mechanism includes a guide groove, a side roller bracket, a first conveying roller, a second conveying roller, a motor, and an adjusting block. The guide groove is symmetrically opened on both sides of the base. An adjusting block is connected to the outer side of the guide groove.

[0023] like Figures 1 to 4 As shown, a lithium battery separator docking and conveying device includes a base 1, a side roller support 6, a lifting seat 4, and a motor 9. A flange 3 is connected to the outer symmetrical axis of the base 1. Flanges 3 are provided on both sides of the separator roller 2. A roller unloading mechanism 15 is provided directly below the separator roller 2. The roller unloading mechanism 15 lifts the bottom end of the separator roller 2 by raising and lowering itself, thereby saving the time required for unloading the separator roller 2. A conveying mechanism 10 is provided on one side of the separator roller 2. The height of the conveying mechanism 10 is dynamically adjusted according to the height of the separator roller 2, thereby meeting the tension requirements during the conveying of the separator and preventing the membrane from becoming loose.

[0024] In this embodiment, the conveying mechanism 10 includes a guide groove 5, a side roller support 6, a first conveying roller 7, a second conveying roller 8, a motor 9, and an adjusting block 16. The guide groove 5 is symmetrically opened on both sides of the base 1. The adjusting block 16 is connected to the outer side of the guide groove 5. The side roller support 6 is connected to the outer side of the adjusting block 16. The motor 9 is connected to the outer side of the side roller support 6. The output end of the motor 9 is connected to one end of the first conveying roller 7. The other end of the first conveying roller 7 is connected to the side roller support 6. The two sides of the second conveying roller 8 are connected to the outer side of the side roller support 6. The side roller support 6 is symmetrically arranged on both sides of the base 1. Multiple sets of positioning holes 18 are equally spaced on the outer side of the guide groove 5. The inner end of one set of positioning holes 18 is connected to a fastener 17. The adjusting block 16 and the guide groove 5 are positioned by inserting the fastener 17 into the through positioning hole 18. As a specific embodiment of the fastener 17 of this utility model, the fastener 17 can be a bolt.

[0025] In this embodiment, the base 1 is connected to the outer side of the adjusting block 16 through the guide groove 5 symmetrically arranged on the outer side. The height of the side roller support 6 and the first and second conveying rollers 7 and 8 are adjusted by the displacement of the adjusting block 16 on the outer side of the guide groove 5.

[0026] In this embodiment, the unloading roller mechanism 15 includes a lifting seat 4, a roller frame 11, a slot 12, a cylinder 13, and a second flange 14. The lifting seat 4 is located directly above the base 1. The cylinder 13 is connected to the outer side of the base 1. The roller frame 11 is located directly above the base 1. The second flange 14 is symmetrically arranged on both sides of the base 1. One side of the second flange 14 is connected to a first flange 3. The output end bearing of the cylinder 13 is connected to the lifting seat 4. Another set of diaphragm rollers 2 is arranged on the outer side of the roller frame 11.

[0027] In this embodiment, the cylinder 13 is connected to the lifting seat 4 at its output end and contacts the outer side of the diaphragm roller 2. The lifting seat 4 is used to lift the bottom end of the diaphragm roller 2, thereby facilitating the lifting and lowering of the diaphragm roller 2 and unloading of the diaphragm roller 2.

[0028] In this embodiment, the base 1 is connected to the bottom end of the roller frame 11 through symmetrical slots 12 at the top. The bottom end of the roller frame 11 is engaged and assembled through the slots 12, which facilitates quick disassembly and replacement of the roller frame 11 and another set of diaphragm rollers 2.

[0029] In practical applications, this lithium battery separator docking and conveying device includes the following tasks:

[0030] Step 1: During the diaphragm transport process, the motor 9 drives the first conveyor roller 7 to rotate. The first conveyor roller 7 and the second conveyor roller 8 are used to transport the diaphragm. The support and downward pressure of the contact surfaces of the first conveyor roller 7 and the second conveyor roller 8 prevent the diaphragm from wrinkling and ensure the smoothness of the transport. After the transport of one set of diaphragm rollers 2 is completed, the height of the side roller support 6 is adjusted to facilitate the adjustment of the height of the first conveyor roller 7 and the second conveyor roller 8.

[0031] Step 2: The operator pulls the side roller brackets 6 on both sides, causing the adjusting block 16 on the outer side of the side roller bracket 6 to slide on the outer side of the guide groove 5, thereby adjusting the height of the side roller bracket 6. Then, the adjusting block 16, the guide groove 5, and the positioning holes 18 on the outer side of the side roller bracket 6 are connected to the fastener 17 through the fastener. (Multiple sets of positioning holes 18 are equally spaced on the outer side of the guide groove 5, which can adjust the positioning height of the side roller bracket 6 according to the usage requirements.) Then, another set of diaphragms is inserted between the first conveyor roller 7 and the second conveyor roller 8 to complete the tension adjustment.

[0032] Step 3: Subsequently, the operator opens cylinder 13, which drives the lifting seat 4 to move vertically upward. The lifting seat 4 lifts the bottom end of the diaphragm roller 2. Then, the operator loosens the bolts between flange 2 14 and flange 1 3, so that the diaphragm roller 2 is separated from the base 1. Cylinder 13 drives the lifting seat 4 to move vertically downward. The lifting seat 4 drives the diaphragm roller 2 to move downward. Then, by rotating the lifting seat 4, the diaphragm roller 2 is rotated, which makes it easier to move the diaphragm roller 2 out.

[0033] Step 4: Then place the new diaphragm and diaphragm roller 2 on the outside of the support seat 4, and then rotate the support seat 4 and diaphragm roller 2 laterally so that the flange 3 and flange 14 on the outside of the diaphragm roller 2 come into contact and lock. When the roller frame 11 separates from the outside of the slot 12, the diaphragm roller 2 installed on the roller frame 11 is replaced without affecting the processing efficiency.

[0034] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
