Description

Technical Field

[0001] The embodiments of the utility model relate to the field of battery manufacturing technology, in particular, to the field of lithium-ion battery cell manufacturing technology. Specifically, the application relates to a diaphragm transmission mechanism and a diaphragm processing device. Background Art

[0002] In the battery manufacturing process, the preparation method of the battery cell mainly adopts a "Z"-shaped stacking scheme, in which the diaphragm needs to be accurately guided to the stacking platform through transmission, and folded in a "Z" shape on the stacking platform and the positive and negative battery poles are alternately stacked on the diaphragm. The diaphragm needs to be guided and transmitted to the stacking platform by the diaphragm unwinding mechanism through the transmission roller, etc. However, when the diaphragm in a free state is transmitted between the stacking platform and the diaphragm unwinding mechanism, the state of the diaphragm in each section is inconsistent, so the tension is different, and the tension of adjacent sections is easy to interfere with each other, resulting in wrinkling, folding, deflection and other precision problems, affecting the production of the battery.

Based on this, the adsorption holes can be densely distributed on the roller surface of the rotating roller body. When the rotating roller body rotates to any angle, there are always adsorption holes in contact with the diaphragm, and an adsorption effect is formed through the adsorption holes and the connected first adsorption channels, thereby improving the adsorption effect of the diaphragm during the transmission of the diaphragm.

[0018] When driven by a driving motor, the rotation speed of the driving motor can be set to adjust the rotation speed of the rotating roller to meet different membrane conveying speed requirements.

[0019] Optionally, the driving connection part includes a driven wheel and a transmission belt, the driven wheel is installed at the second end of the rotating roller body, the driving end of the driving motor is provided with a driving wheel, the transmission belt is arranged in a ring shape, the two ends of the transmission belt are respectively sleeved on the driven wheel and the driving wheel, the transmission belt is respectively meshed with the driven wheel and the driving wheel, and the driving motor drives the driving wheel to rotate, thereby driving the driven wheel and the rotating roller body to rotate.

[0020] By adopting the mode of using a conveyor belt to drive the driving wheel and the driven wheel, the structure is simple, easy to implement and the cost is low.

[0021] A second aspect of the present application provides a membrane processing device, the membrane processing device is used to process and transport membranes, the membrane processing device comprises a frame and a first processing mechanism, a second processing mechanism and a membrane transport mechanism according to any one of the first aspects mounted on the frame, the membrane passes through the first processing mechanism, the membrane transport mechanism and the second processing mechanism in sequence;

[0023] The membrane transport mechanism is disposed between the first processing mechanism and the second processing mechanism, and the rotating roller body contacts and supports the membrane to guide and transport the membrane transported from the first processing mechanism to the second processing mechanism.

[0024] The diaphragm processing equipment provided in the present application is configured such that a rotating roller in a diaphragm transmission mechanism is disposed on the transmission path of the diaphragm and between a first processing mechanism and a second processing mechanism.

[0025] Optionally, the first processing mechanism includes a support roller, which is arranged on a track and is used to contact and support the diaphragm, and the support roller can be driven to slide back and forth on the track, and the reciprocating sliding can change the length of the diaphragm between the support roller and the rotating roller body of the diaphragm transmission mechanism.

[0026] The reciprocating sliding of the support roller can change the length of the diaphragm between the support roller and the rotating roller body of the diaphragm transmission mechanism, which can not only achieve stable support for the diaphragm, but also achieve recovery and adjustment of the diaphragm length. Moreover, since the diaphragm transmission mechanism blocks the tension, the tension fluctuation caused by the reciprocating sliding of the support roller will not be transmitted to the downstream.

[0037] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0038] Combination Figure 1 , Figure 2 ,as well as Figure 3 As shown, this embodiment provides a diaphragm transmission mechanism 1, wherein: Figure 1 It is a three-dimensional schematic diagram of a diaphragm transmission mechanism 1, comprising a support shaft 11, a connecting portion 12, and a rotating roller body 13; Figure 2 is a three-dimensional schematic diagram of a diaphragm transmission mechanism 1, the schematic structure includes a support shaft 11 and a connecting portion 12, Figure 3 It is a schematic structural diagram of the rotating roller body 13.

[0039] Specifically, the diaphragm transmission mechanism 1 includes a support shaft 11, a connecting part 12 and a rotating roller body 13 with adsorption holes 131 formed on the surface. One end of the support shaft 11 is fixedly connected to the support structure of the battery cell processing equipment. The support structure mainly plays the role of fixing the diaphragm transmission mechanism 1. The other end of the support shaft 11 is fixedly connected to the connecting part 12; the rotating roller body 13 is sleeved on the support shaft 11 and can rotate with the support shaft 11 to be used for conveying the diaphragm (not shown in the drawings).

[0040] For example, the rotating roller 13 can be sleeved on the support shaft 11 through a bearing. Specifically, a bearing is sleeved on the support shaft 11, and the rotating roller 13 is sleeved outside the bearing, so that the rotating roller 13 rotates around the support shaft 11, wherein the rotating roller 13 can adopt a hollow cylindrical structure, the inside of which is hollow and sleeved on the bearing on the support shaft 11, and the outside is used for contacting and conveying the diaphragm. In addition, the bearing can be set at both ends of the support shaft 11, or it can be set in the middle of the support shaft 11. In this embodiment, the bearing is set on one end of the support shaft 11 close to the connecting portion 12.

[0041] like Figure 3 As shown, as described above, the rotating roller body 13 adopts a hollow cylindrical structure and is sleeved on the support shaft 11, and a plurality of adsorption holes 131 are formed on the rotating roller body 13, and the adsorption holes 131 extend from the outer surface of the rotating roller body 13 to the inner surface, wherein the adsorption holes 131 are arranged in an array along the circumferential direction of the rotating roller body 13 on the surface of the rotating roller body 13, and are also arranged in an array along the length direction of the rotating roller body 13, thereby forming a plurality of rows of adsorption holes 131 in an array on the outer surface of the rotating roller body 13; by arranging a plurality of adsorption holes 131 in an array in both the circumferential direction and the length direction of the rotating roller body 13, the adsorption holes can be distributed more densely, so that when the rotating roller body rotates to any angle, there are always adsorption holes in contact with the diaphragm, and an adsorption effect is formed through the adsorption holes and the first adsorption channel connected, therefore, this arrangement can improve the adsorption force of the outer surface of the rotating roller body 13 on the diaphragm.

[0042] In addition, a plurality of first adsorption channels 132 are formed on the first end surface of the rotating roller body 13 near the connecting portion 12, and each first adsorption channel 132 extends along the length direction of the rotating roller body 13. Each first adsorption channel 132 is connected to at least one row of adsorption holes 131 arranged along the length direction of the rotating roller body. Based on this connection, the adsorption force is transmitted to adsorb the diaphragm in contact with the surface of the rotating roller body 13.

[0043] like Figure 2As shown, the connecting portion 12 can be coaxially fixedly connected to the support shaft 11, and the connecting portion 12 fits the first end face of the rotating roller body 13, the connecting portion 12 has a second end face facing the aforementioned first end face, and a second adsorption channel 121 is formed on the second end face of the connecting portion 12, one end of the second adsorption channel 121 is connected to a plurality of first adsorption channels 132 located on the first end face, and the other end of the second adsorption channel 121 is connected to a vacuum generator (not shown in the drawings), so that the negative pressure generated by the vacuum generator is transferred through the second adsorption channel 121, the first adsorption channel 132, and the adsorption hole 131 in sequence to adsorb the diaphragm located on the surface of the rotating roller body 13.

[0044] The diaphragm transmission mechanism 1 provided in the present application has adsorption holes 131 formed on the surface of the rotating roller body 13 which are connected to the vacuum generator. Therefore, in the area where the rotating roller body 13 contacts the diaphragm, an adsorption effect can be generated through the adsorption holes 131. This adsorption effect can isolate and disconnect the tension on the diaphragm to avoid interference with the diaphragm transmission.

[0045] like Figure 3 As shown, in one embodiment, there are multiple first adsorption channels 132, and the multiple first adsorption channels 132 are all arranged on the side wall of the first end surface of the rotating roller body 13, and extend on the rotating roller body 13 in a direction away from the first end surface, and the multiple first adsorption channels 132 are arranged in the circumferential direction of the first end surface, and each first adsorption channel 132 is connected with at least one row of adsorption holes 131. By arranging multiple first adsorption channels 132 in the circumferential direction (circumferential direction) of the first end surface, the number of first adsorption channels 132 is increased, and each first adsorption channel 132 is connected with at least one row of adsorption holes 131, so that when the rotating roller body 13 rotates at any angle, the area in contact with the diaphragm has adsorption holes 131 that generate adsorption force on the diaphragm through the first adsorption channels 132, thereby improving the adsorption effect on the diaphragm on the surface of the rotating roller body 13.

[0046] like Figure 2 As shown, in one embodiment, a plurality of second adsorption channels 121 are also provided, and the plurality of second adsorption channels 121 are arranged circumferentially on the side wall (i.e., the second end face) of the connecting portion 12, so as to increase the number of second adsorption channels 121 connected to the first adsorption channel 132, and through the vacuum generator connected to the other end of the second adsorption channel 121, the adsorption effect on the diaphragm on the surface of the rotating roller body 13 is improved.

[0047] Continue as Figure 2As shown, when the second adsorption channel 121 is provided along the circumferential direction on the second end face of the connecting portion 12 (the second end face is attached to the rotating roller body 13), the area where the second adsorption channel 121 is located does not exceed half of the circumferential direction of the second end face. It can be understood that the diaphragm is located on the surface of the rotating roller body 13 and rolls with the rotating roller body 13, and the contact area between the diaphragm and the surface of the rotating roller body 13 is small. In this way, by providing the second adsorption channel 121 at the side end corresponding to the contact area of ​​the diaphragm, effective adsorption of the diaphragm can be ensured.

[0048] Continue as Figure 2 As shown, in one embodiment, the connecting portion 12 is cylindrical, and the cylindrical connecting portion 12 has the same central axis as the rotating roller body 13 and the supporting shaft 11. When a plurality of second adsorption channels 121 are provided on the second end surface of the connecting portion 12, the channel openings of the second adsorption channels 121 are arranged circumferentially along the second end surface. The channel openings of the second adsorption channels 121 can be in various shapes such as circular holes and arc-shaped waist holes. Correspondingly, the channel openings of the first adsorption channels 132 are set to be circular, arc-shaped or other shapes.

[0049] Exemplarily, when the shape of the channel opening of the second adsorption channel 121 is a circular hole, the circular diameter of the channel opening of the first adsorption channel 132 is smaller than the circular diameter of the channel opening of the second adsorption channel 121; when the shape of the channel opening of the second adsorption channel 121 is an arc-shaped waist hole, the channel opening of the first adsorption channel 132 is set to be a circle with a diameter the same as the width of the channel opening of the second adsorption channel 121; the shape of the channel opening may not be limited to the aforementioned situation, ensuring that the channel opening size of the second adsorption channel 121 is larger than the channel opening size of the first adsorption channel 132, and the channel opening of this size of the second adsorption channel 121 covers the channel opening of the first adsorption channel 132, which helps to improve the adsorption effect on the diaphragm 16 on the surface of the rotating roller body 13.

[0050] Combination Figure 1 and Figure 2 As shown, in one embodiment, the diaphragm transmission mechanism 1 further includes a driving motor 14 and a driving connection portion 15, and the driving motor 14 drives the rotating roller body 13 to rotate around the support shaft 11 through the driving connection portion 15. Specifically, the driving connection portion 15 is formed at one end of the rotating roller body 13 away from the connection portion 12, and the driving connection portion 15 is connected to the driving motor 14, and the driving motor 14 drives the connection portion 15 to rotate so that the rotating roller body 13 rotates on the support shaft 11.

[0051] In a specific implementation, the drive connection part 15 can be a rotating shaft, which is fixedly connected to the rotating roller body 13, and the motor drives the rotating shaft to rotate so that the rotating roller body 13 rotates on the support shaft 11. The drive connection part 15 can also be a gear structure, which is fixedly connected to the rotating roller body 13, and the motor drives the gear structure to rotate so that the rotating roller body 13 rotates on the support shaft 11. The drive connection part 15 can also be fixedly connected to the rotating roller body 13 using other rotating structures, and the drive motor 14 drives the drive connection part 15 to rotate so that the rotating roller body 13 rotates on the support shaft 11.

[0052] In addition, when the driving motor 14 is used for driving, the rotation speed of the driving motor 14 can be set so as to adjust the diaphragm transmission speed so as to meet different diaphragm transmission speed requirements.

[0053] Combination Figure 1 , Figure 2 as well as Figure 3 As shown, in one embodiment, the driving of the rotating roller body 13 by the electrode is realized by using a conveyor belt 152 to drive the driving wheel 151 and the driven wheel 133. Specifically, the driving connection part 15 includes a driven wheel 133 and a transmission belt 152, the driven wheel 133 is installed at the second end of the rotating roller body 13, the driving wheel 151 is installed at the driving end of the driving motor 14, and the two ends of the transmission belt 152 are respectively sleeved on the driven wheel 133 and the driving wheel 151, and meshed with the driven wheel 133 and the driving wheel 151, and the driving motor 14 drives the driving wheel 151 to rotate, so as to drive the driven wheel 133 and the rotating roller body 13 to rotate. For example, the transmission belt 152 is set in a ring shape and sleeved on the driving wheel 151 and the driven wheel 133. By using the conveyor belt 152 to drive the driving wheel 151 and the driven wheel 133, the structure is simple, easy to implement, and the cost is low.

[0054] like Figure 4 As shown, based on the same application concept, the embodiment of the present application further provides a diaphragm processing device, wherein the diaphragm processing device is used to process and transport the diaphragm 16, and the diaphragm processing device includes a frame 4 and a first processing mechanism 2, a second processing mechanism 3 and a diaphragm transport mechanism 1 according to any of the above embodiments installed on the frame 4. The frame 4 is a structural member arranged according to the diaphragm processing device and the stacking platform, which is used to fix the first processing mechanism 2, the second processing mechanism 3 and the diaphragm transport mechanism 1, and its specific size and structure can be determined according to requirements.

[0055] In the diaphragm processing equipment, the diaphragm 16 passes through the first processing mechanism 2, the diaphragm transmission mechanism 1, and the second processing mechanism 3 in sequence; the first processing mechanism 2 and the second processing mechanism 3 respectively process and control the diaphragm 16, for example, at least one of tension control, buffering, stroke correction, and guided transmission is implemented, and the tension, position, stroke, etc. of the processed diaphragm 16 are ensured to meet the subsequent process flow requirements through the first processing mechanism 2 and the second processing mechanism 3. Among them, the distance between the first processing mechanism 2 and the second processing mechanism 3 is relatively far, and the diaphragm transmission mechanism 1 is set between the first processing mechanism 2 and the second processing mechanism 3, and the diaphragm 16 is supported by the rotating roller body 13 to guide and transport the diaphragm 16 transmitted from the first processing mechanism 2 to the second processing mechanism 3.

[0056] The diaphragm processing equipment provided in the present application is configured such that the diaphragm transmission mechanism 1 is disposed on the transmission path of the diaphragm 16 and between the first processing mechanism 2 and the second processing mechanism 3. The adsorption holes 131 formed on the surface of the rotating roller body 13 in the diaphragm transmission mechanism 1 are connected to the vacuum generator, so that an adsorption effect can be generated when contacting the diaphragm 16. This adsorption effect can isolate and disconnect the tension of the diaphragm 16 of the first processing mechanism 2, thereby avoiding interference with the transmission and processing of the diaphragm 16 of the downstream second processing mechanism 3.

[0057] like Figure 4 As shown, in one embodiment, the first processing mechanism 2 includes a support roller 21 and a track 22, the support roller 21 is slidably arranged on the track 22, and the support roller 21 is on the transmission path of the diaphragm 16 and contacts the support diaphragm 16. The support roller 21 can be driven to slide back and forth on the track 22, and the length of the diaphragm 16 between the support roller 21 and the rotating roller body 13 of the diaphragm transmission mechanism 1 can be changed by the reciprocating sliding, so as to realize the recovery of the diaphragm 16 transmitted by the second processing mechanism 3.

[0058] like Figure 4 As shown, in one embodiment, the second handling mechanism 3 is used to guide the membrane 16 to be transported to a lamination platform (not shown in the drawings).
