DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] For example, see Figure 1-Figure 8 A drying device for processing a battery separator is used to dry a battery separator 100. The drying device for processing a battery separator comprises a workbench 200. A drying machine 300 is arranged in the middle of the workbench 200. The battery separator 100 is transmitted through the drying machine 300. Two first conveying mechanisms 400 are symmetrically arranged on the upper and lower sides of the workbench 200. The two first conveying mechanisms 400 are used to convey absorbent paper 500 into the dryer 300. The absorbent paper 500 is wrapped on both sides of the battery separator 100 to assist in drying. The first conveying mechanism 400 includes a winding drum 410, a first conveying roller 420 and a second conveying roller 430 rotatably disposed on the workbench 200, wherein the first conveying roller 420 and the second conveying roller 430 are respectively located on the left and right sides of the dryer 300, and the absorbent paper 500 is wound around the winding drum 410, and the absorbent paper 500 is transmission-connected to the first conveying roller 420 and the second conveying roller 430; The first conveying mechanism 400 further includes a third conveying roller 440, a fourth conveying roller 450 and a fifth conveying roller 460 rotatably disposed on the workbench 200, and the absorbent paper 500 is transmission-connected to the third conveying roller 440, the fourth conveying roller 450 and the fifth conveying roller 460; The third conveying roller 440 is located on the left side of the dryer 300, and the winding drum 410, the third conveying roller 440 and the first conveying roller 420 are arranged in an inclined V shape. The fourth conveying roller 450 and the fifth conveying roller 460 are respectively located on both sides of the absorbent paper 500, and the fourth conveying roller 450 and the fifth conveying roller 460 rotate in opposite directions to convey the absorbent paper 500.

[0032] In this embodiment: This device is a link in the battery separator 100 production line. At the upstream of the production line, the battery separator 100 is continuously transported to the right through the dryer 300. When the battery separator 100 enters the dryer 300, the upper and lower first conveying mechanisms 400 convey two layers of absorbent paper 500 into the dryer 300. The two layers of absorbent paper 500 are respectively wrapped on the upper and lower sides of the battery separator 100. The absorbent paper 500 absorbs moisture to assist drying, which can reduce the set drying temperature and drying time to a certain extent.

[0033] It should be supplemented that the absorbent paper 500 can be a film product of other absorbent materials and has the property of high temperature resistance. As the dryer 300 is a prior art, its specific structure and working principle are not described in detail.

[0034] Specifically, taking a group of first conveying mechanisms 400 located at the lower side as an example, the absorbent paper 500 is wound and installed on the winding drum 410. The winding drum 410 rotates clockwise so that the absorbent paper 500 passes through the third conveying roller 440, the first conveying roller 420 and the second conveying roller 430 in a clockwise direction. The function of the third conveying roller 440 is to tighten the absorbent paper 500 to maintain transmission balance.

[0035] After passing through the second conveying roller 430, the absorbent paper 500 passes through the fourth conveying roller 450 and the fifth conveying roller 460. The fourth conveying roller 450 rotates clockwise and the fifth conveying roller 460 rotates counterclockwise to convey the absorbent paper 500 downward. A storage device can be set at the lower side of the absorbent paper 500 for collection.

[0036] It should be supplemented that the winding drum 410 is detachably mounted on the workbench 200 and can be replaced after the absorbent paper 500 is used up.

[0037] Embodiment 2: This embodiment is an improvement on Embodiment 1. For details, please refer to Figure 1-Figure 9 The dryer 300 is provided with a second conveying mechanism 600, the second conveying mechanism 600 includes a plurality of conveying components 610, and the conveying components 610 include a sixth conveying roller 611 and a seventh conveying roller 612 rotatably disposed in the dryer 300; The absorbent paper 500 located at the lower side is connected to a plurality of sixth conveying rollers 611 by transmission, and the absorbent paper 500 located at the upper side is connected to a plurality of seventh conveying rollers 612 by transmission; The temperature in the dryer 300 decreases step by step from left to right, and a plurality of conveying components 610 are arranged in a V shape.

[0038] In this embodiment, in order to ensure that the battery separator 100 can be well supported in the dryer 300 and will not tear due to lack of support force due to a long transmission distance, a plurality of sixth conveying rollers 611 are provided to support the lower side of the absorbent paper 500 located at the lower side, and the plurality of sixth conveying rollers 611 also rotate clockwise. A plurality of seventh conveying rollers 612 are provided to support the upper side of the absorbent paper 500 located at the upper side, and the plurality of seventh conveying rollers 612 rotate counterclockwise.

[0039] In addition, the dryer 300 can be set with a temperature gradient that gradually decreases from left to right. Accordingly, a plurality of conveying components 610 are set in a V shape, so that in the high temperature area on the left, the battery separator 100 and the two layers of absorbent paper 500 are tilted toward the lower right corner, and the water released by the battery separator 100 is mainly concentrated on the absorbent paper 500 on the lower side and will not flow back. After reaching the relatively low temperature area in the middle and right side, the battery separator 100 and the two layers of absorbent paper 500 are tilted and transported to the upper right corner.

[0040] Embodiment 3: This embodiment is an improvement made on the basis of Embodiment 2. For details, please refer to Figure 1-Figure 9 The conveying assembly 610 further includes a slide 613 and a first spring 614, the slide 613 is slidably connected to the workbench 200, the seventh conveying roller 612 is rotatably connected to the slide 613, and the slide 613 is elastically connected to the workbench 200 through the first spring 614; The second conveying mechanism 600 further includes a gradual pressing assembly 620, which is used to push the plurality of seventh conveying rollers 612 downward from left to right in sequence, so that the absorbent paper 500 located on the upper side is gradually pressed against the upper side of the battery separator 100 from left to right; The gradual pressing assembly 620 includes a V-shaped rod 621, and the left and right ends of the V-shaped rod 621 are respectively provided with a first rotating shaft 622 and a guide rod 623, the first rotating shaft 622 is rotatably connected to the workbench 200, and an arc groove 624 is provided on the workbench 200, and the guide rod 623 is slidably connected in the arc groove 624, and the center of the arc groove 624 is coaxial with the first rotating shaft 622; The gradual pressing assembly 620 further includes a cylinder 625, and a second rotating shaft 626 and a third rotating shaft 627 are respectively disposed at both ends of the cylinder 625, the second rotating shaft 626 is rotatably connected to the workbench 200, and the third rotating shaft 627 is rotatably connected to the V-shaped rod 621; A slide bar 628 is slidably disposed in the slide seat 613 , and the slide bar 628 is elastically connected to the slide seat 613 via a second spring 629 .

[0041] In this embodiment, the sixth conveying roller 611 is fixed in position, and the seventh conveying roller 612 can slide perpendicularly to its corresponding sixth conveying roller 611 .

[0042] During the installation of the battery separator 100, from left to right, the battery separator 100 is first inserted between two layers of absorbent paper 500 manually or mechanically, and then the battery separator 100 passes through the first sixth conveyor roller 611. At this time, the first seventh conveyor roller 612 is supported by the elastic force of the first spring 614 and is not pressed against the battery separator 100, so that the battery separator 100 can pass through easily.

[0043] After the battery separator 100 passes through the first conveying assembly 610, the first seventh conveying roller 612 presses against the battery separator 100 again, so that the upper layer of absorbent paper 500 is pressed against the upper side of the battery separator 100. At this time, the first sixth conveying roller 611 and the seventh conveying roller 612 form a stable support for the battery separator 100 and the two layers of absorbent paper 500.

[0044] The first sixth conveying roller 611 on the lower side actively rotates clockwise, and the seventh conveying roller 612 on the upper side passively rotates counterclockwise, so that the battery separator 100 continues to be conveyed to the right. Similarly, several seventh conveying rollers 612 press the battery separator 100 from left to right in sequence, so that the battery separator 100 can pass through the dryer 300 smoothly.

[0045] Specifically, when the plurality of seventh conveying rollers 612 are driven to move downward in sequence, the cylinder 625 is extended to push the V-shaped rod 621 to move downward along the track of the arc groove 624 based on the first rotating shaft 622 and contact the plurality of sliding rods 628 in sequence from left to right.

[0046] Under the elastic support of the second spring 629, the slide bar 628 first drives the slide seat 613 and the seventh conveying roller 612 to move downward together, until the slide seat 613 reaches the point where the absorbent paper 500 is pressed against the battery separator 100, and the grooves provided on the workbench 200 and the dryer 300 restrict the seventh conveying roller 612 and the slide seat 613 from moving further downward. At this time, the V-shaped rod 621 further pushes the slide bar 628 downward, so that the slide bar 628 moves downward relative to the slide seat 613, compressing the second spring 629.

[0047] It should be supplemented that the driving speed of the cylinder 625 is not fixed, so that the plurality of seventh conveying rollers 612 move downward at a uniform speed.
