Description

Technical Field

[0001] This utility model relates to the field of battery separator technology, specifically to a battery cell separator feeding structure. Background Technology

[0002] The separator is mainly placed between the positive and negative electrodes inside the battery cell. It plays a role in blocking the transfer of electrons between the positive and negative electrodes, preventing short circuits, and allowing lithium ions to pass through and transfer between the positive and negative electrodes, so that the battery can work normally. During the battery production process, the separator is stored in rolls. When assembling the battery, the separator rolls need to be loaded onto the battery production equipment for unwinding.

[0003] As disclosed in the authorization announcement number CN206367182U, a blister film feeding structure includes a material rack and a feeding mechanism. The feeding mechanism includes a rotating shaft that is rotatably connected to the material rack. Two feeding plates are symmetrically arranged on the left and right sides of the front side of the rotating shaft. A cylinder is arranged on the rear side of the rotating shaft. The cylinder rod of the cylinder is connected to the feeding plate. Two feeding slots are symmetrically arranged on the left and right sides of the upper part of the material rack. A limiting mechanism is provided on the inner side of the feeding plate. The limiting mechanism includes a limiting cylinder and a limiting plate. The limiting plate is located on the inner side of the feeding plate. The limiting cylinder is fixed on the outer side of the feeding plate. The cylinder rod of the limiting cylinder passes through the feeding plate and is connected to the limiting plate. Two guide posts are symmetrically arranged on the front and rear sides of the cylinder rod. This utility model has a reasonable design and improves the feeding efficiency.

[0004] However, in the above scheme, whenever the diaphragm roll is used up, the empty diaphragm roll needs to be removed manually, and then the feeding structure is used to send the new diaphragm roll to the feeding trough. This cycle is repeated. However, in this feeding method, when the feeding trough is at a high position, it is not convenient to remove the empty diaphragm roll manually. Utility Model Content

[0005] The purpose of this invention is to provide a battery cell separator feeding structure to solve the technical problem in the prior art that an empty separator roll cannot be removed.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0007] A battery cell separator feeding structure includes a base plate, two parallel side plates are provided on the upper surface of the base plate, a plurality of support plates are arrayed on the top of each side plate, a temporary storage groove is provided on the top of each support plate, and a placement groove is provided on the top of each side plate.

[0008] The stepping structure includes a main plate, on the upper surface of which a plurality of drive slots are arrayed. Each drive slot has a groove on its top. One drive slot corresponds to the position of a placement slot, and the remaining drive slots correspond to the positions of corresponding temporary storage slots. The top of the base plate is provided with a drive structure that drives the main plate to perform circular motion.

[0009] As a further embodiment of this utility model: the driving structure includes linkage rods, two linkage rods are provided and arranged in an array, each linkage rod is rotatable on one side of the main plate via a rotating shaft, and a rotating rod is fixed to the end of each linkage rod away from the rotating shaft. A support frame for supporting the rotating rod is provided on the top of the base plate, and the rotating rod is rotatably connected to the support frame. A synchronous pulley is coaxially provided on the outer side of each rotating rod, and a synchronous belt is provided on the outer side of the two synchronous pulleys. A motor is fixedly provided on one of the support frames, and the output end of the motor is fixedly connected to the corresponding rotating rod.

[0010] As a further embodiment of this utility model: an upwardly inclined slant bar is provided at the top of the side plate away from the placement groove.

[0011] As a further embodiment of this utility model: a downwardly inclined sliding rod is provided at the top of the side plate near the placement groove, and the sliding rod is used to guide the empty reel.

[0012] As a further embodiment of this utility model: a collection box for collecting empty spools is provided at the bottom of the end of the sliding rod away from the side plate.

[0013] As a further embodiment of this utility model, a rubber pad is provided in the groove at the top of the drive slot.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model uses a drive structure to drive the main plate to make a circular motion. The drive groove at the top of the main plate lifts the membrane roll in the corresponding temporary storage groove and moves it to the next temporary storage groove or placement groove. The empty roll in the placement groove will be lifted and unloaded by the corresponding drive groove. The new membrane roll in the previous temporary storage groove will be loaded into the placement groove. This avoids the need to manually remove the empty membrane roll every time it is used up, thus improving the loading efficiency.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-3 As shown, a battery cell separator feeding structure includes a base plate 1 and a stepping structure. Two parallel side plates 2 are fixedly arranged on the upper surface of the base plate 1. Several support plates 4 are fixedly arranged in an array on the top of the side plates 2. Each support plate 4 has a temporary storage groove 5 on its top. The temporary storage grooves 5 on the top of the two side plates 2 correspond one-to-one. The two ends of the roller shaft with the rolled separator film are placed in the corresponding temporary storage grooves 5. The top of the side plate 2 is also provided with a placement groove 3.

[0024] The stepping structure includes a main plate 7. Several drive slots 8 are fixedly arranged in an array on the upper surface of the main plate 7. Each drive slot 8 has a groove on its top for temporarily storing the roller. One drive slot 8 corresponds to the position of the placement slot 3, and the other drive slots 8 correspond to the positions of the corresponding temporary storage slots 5. The top of the base plate 1 is provided with a drive structure that drives the main plate 7 to perform circular motion. When the drive slot 8 lifts the roller and moves half a circle, the drive slot 8 lifts the film roll in the corresponding temporary storage slot 5 and steps it into the next temporary storage slot 5 or the placement slot 3. Then, the empty roll in the placement slot 3 will be lifted and unloaded by the corresponding drive slot 8. The new film roll in the previous temporary storage slot 5 will be loaded into the placement slot 3. This avoids the need to manually remove the empty diaphragm roll every time it is used up, thus improving the loading efficiency.

[0025] In some specific implementation plans, such as Figure 2 or Figure 3As shown, to facilitate the circular motion of the main plate 7, the drive structure includes two linkage rods 9 arranged in an array. Each linkage rod 9 rotates on one side of the main plate 7 via a rotating shaft. A rotating rod 10 is fixedly connected to the end of each linkage rod 9 away from the rotating shaft. A support frame 14 is provided on the top of the base plate 1 to support the rotating rod 10. The rotating rod 10 is rotatably connected to the support frame 14. A synchronous pulley 11 is coaxially provided on the outer side of each rotating rod 10. A synchronous belt 12 is provided on the outer side of the two synchronous pulleys 11. A motor 13 is fixedly provided on one of the support frames 14. The output end of the motor 13 is fixedly connected to the corresponding rotating rod 10. When the motor 13 is started, it drives the corresponding rotating rod 10 to rotate. The rotating rod 10 drives the outer synchronous pulley 11 to rotate synchronously. Since the synchronous belt 12 is provided on the outer side of the two synchronous pulleys 11, the two rotating rods 10 drive the corresponding linkage rod 9 to rotate, thereby causing the main plate 7 connected to the other end of the linkage rod 9 to perform circular motion, which causes the main plate 7 to drive the drive groove 8 to perform stepping motion on the scroll.

[0026] In some specific implementation plans, such as Figure 1 As shown, in order to facilitate the storage of multiple isolation film rolls, an upwardly inclined bar 6 is provided at the top of the side plate 2 away from the placement groove 3.

[0027] In some specific implementation plans, such as Figure 1 As shown, in order to facilitate the collection of empty spools after use, a downwardly inclined sliding rod 15 is fixedly installed on the top of the side plate 2 near the placement slot 3. The sliding rod 15 is used to guide the empty spools. A collection box 16 for collecting empty spools is provided at the bottom of the end of the sliding rod 15 away from the side plate 2. The collection box 16 collects the empty spools that roll off the sliding rod 15, which facilitates the unified processing of the empty spools in the collection box 16 later.

[0028] In some specific implementations, to prevent the isolation membrane from being scratched during transportation, a rubber pad 17 is fixedly installed in the groove at the top of the drive slot 8.

[0029] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios:

[0030] The start motor 13 drives the corresponding rotating rod 10 to rotate, and the rotating rod 10 drives the outer synchronous wheel 11 to rotate synchronously. Since the two synchronous wheels 11 are equipped with synchronous belts 12, the two rotating rods 10 drive the corresponding linkage rod 9 to rotate, thereby causing the main plate 7 connected to the other end of the linkage rod 9 to perform circumferential motion. When the main plate 7 performs circumferential motion, when the drive groove 8 lifts the roller shaft and moves half a circle, the drive groove 8 at the top of the main plate 7 lifts the film roll in the corresponding temporary storage groove 5 to step into the next temporary storage groove 5 or the placement groove 3. Then, the empty roll in the placement groove 3 will be lifted and unloaded by the corresponding drive groove 8, and the new film roll in the previous temporary storage groove 5 will be loaded into the placement groove 3. This avoids the need to manually remove the empty diaphragm roll every time it is used up, thus improving the loading efficiency.

[0031] The foregoing has described several embodiments of this utility model in detail, but these embodiments are not limited thereto and should not be considered as limiting the scope of this utility model. All equivalent changes and improvements made within the scope of the claims of this utility model should still fall within the patent coverage of this utility model.
