Description

Technical Field

The utility model relates to the technical field of battery production equipment, in particular to a tape threading device, a pole piece coating oven and a battery production line.

Background

In some material belt processing devices, such as a battery pole piece coating oven, the condition of belt replacement or belt breakage occurs in the running process of the device, and at this time, the broken end on one side needs to pass through the device to be connected with the broken end on the other side, and then the processing is resumed. If the process adopts manual operation, the condition of hand cut and scald is easy to cause, and meanwhile, the channels of some material belt processing equipment are longer, so that broken ends cannot pass through manually.

To solve this problem, some ovens in the prior art are provided with a threading structure. For example, in the technical solution disclosed in chinese patent No. cn202021377901.X, the threading structure includes two reels respectively located at the front and rear sides of the device, and traction belts are provided on the two reels and are driven to move by rotation of the reels. When the broken ends are required to be connected, the broken ends on one side are connected to the traction belt, the traction belt moves to drive the broken ends to the other side of the equipment, and then an operator connects the two broken ends.

However, in the above scheme, since the threading structure is fixedly arranged, in order to make the traction belt not interfere with the belt processing, the threading structure needs to be arranged at the side part of the oven so as to avoid the processing channel in the middle part. And the threading structure needs to be provided with two groups, so that both sides of the material belt can be supported when the broken ends are moved. On the one hand, the structure is provided with two groups of threading structures, the cost is higher, and on the other hand, if the traction belts of the threading structures on the two sides are asynchronous or inconsistent in tension, the material belts can be damaged by tearing.

The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.

In addition, the technical features of the different embodiments of the present utility model described below may be combined with each other as long as they do not collide with each other.

As shown in fig. 1 to 5, an embodiment of the threading device according to the present utility model includes a traction belt device. The traction belt device comprises a first winding and unwinding mechanism 2, a second winding and unwinding mechanism 3 and a traction belt 30, wherein the first winding and unwinding mechanism 2 and the second winding and unwinding mechanism 3 are respectively and movably arranged on the front side and the rear side of the material belt processing equipment, and two ends of the traction belt 30 are respectively connected with the first winding and unwinding mechanism 2 and the second winding and unwinding mechanism 3 and penetrate through the oven body 1.

By the technical scheme of the embodiment, the traction belt 30 can move along the front-back direction of the material belt processing equipment under the drive of the first winding and unwinding mechanism 2 and the second winding and unwinding mechanism 3, and the first winding and unwinding mechanism 2 and the second winding and unwinding mechanism 3 can move, so that the traction belt 30 can be driven to move relative to the width direction of the material belt processing equipment. When the broken ends are required to be threaded, the first winding and unwinding mechanism 2 and the second winding and unwinding mechanism 3 move the traction belt 30 to the middle part of a processing channel of the material belt processing equipment, and the middle part of the material belt is connected to the traction belt 30. The first winding and unwinding mechanism 2 and the second winding and unwinding mechanism 3 move the traction belt 30 so as to move the broken end from one side of the belt processing apparatus to the other side. When the broken ends are not needed to be penetrated, the first winding and unwinding mechanism 2 and the second winding and unwinding mechanism 3 move the traction belt to the side part of the belt processing equipment, so that the transmission and the processing of the belt are not affected. Only one group of traction belt devices are arranged in the structure, so that the cost is low, and the situation of tearing the material belt can not occur. Therefore, the technical scheme of the embodiment solves the defects that the broken end and belt penetrating device of the material belt processing equipment in the prior art is high in cost and easy to cause material belt damage.

It should be noted that, in this embodiment, the application of the tape threading device to the pole piece coating oven in the battery production line is taken as an example, that is, the above-mentioned tape processing apparatus includes the oven body 1. However, it will be appreciated by those skilled in the art that any apparatus for processing a web may be used in the solution of this embodiment, for example, the web processing apparatus may be a web coating line. The solution of this example is therefore not limited to use in battery pole piece processing nor in pole piece coating ovens, and the following description is therefore not to be construed as limiting the application of the tape threading device of this embodiment.

As shown in fig. 1 to 5, the first winding and unwinding mechanism 2 includes a first base 10, and a belt feeding structure 11 and a first driving structure 12 are disposed on the first base 10. The first driving structure 12 is adapted to drive the belt feeding structure 11 to move on the first base 10 in a first direction. The second winding and unwinding mechanism 3 comprises a second base 20, the second base 20 is opposite to the first base 10 along a second direction, a winding structure 21 and a second driving structure 22 are arranged on the second base 20, and the second driving structure 22 is suitable for driving the winding structure 21 to move on the second base 20 along the first direction. Both ends of the traction belt 30 are respectively connected with the belt feeding structure 11 and the belt collecting structure 21.

As can be seen in connection with fig. 1, the first direction mentioned above refers to the front-rear direction along the oven body 1, i.e. along the length direction of the oven body 1 (along the direction of the transport stream of the pole piece strip). That is, one of the first chassis 10 and the second chassis 20 is disposed at the front side of the oven body 1, and the other is disposed at the rear side of the oven body 1.

As can be seen in connection with fig. 4 and 5, the second direction mentioned above refers to the left-right direction along the oven body 1, i.e. along the width direction of the oven body 1 (along the direction of transport flow perpendicular to the pole piece strip). That is, the first driving structure 12 can drive the belt feeding structure 11 to move along the width direction of the oven body 1, and the second driving structure 22 can drive the belt collecting structure 21 to move along the width direction of the oven body 1.

In this embodiment, the first base 10 is disposed at an upstream position of the oven body 1, the belt feeding structure 11 is used for feeding out the traction belt 30, the second base 20 is disposed at a downstream position of the oven body 1, and the belt retracting structure 21 is used for retracting the traction belt 30. Both ends of the traction belt 30 are respectively connected with the belt feeding structure 11 and the belt collecting structure 21 and pass through the oven body 1. When the belt feeding structure 11 and the belt collecting structure 21 operate, the traction belt 30 can be driven to move along the circulation direction of the pole piece material belt.

In the present embodiment, the belt feeding structure 11 and the belt collecting structure 21 move synchronously in the first direction, and since both ends of the traction belt 30 are connected to the belt feeding structure 11 and the belt collecting structure 21, the traction belt 30 as a whole can move in the first direction.

When the broken ends of the pole piece material belts are required to be worn, the first driving structure 12 drives the belt conveying structure 11 to move, and meanwhile, the second driving structure 22 drives the belt collecting structure 21 to move, so that the traction belt 30 integrally moves to the middle of the processing channel. The broken ends are connected (e.g., adhered, bound, etc.) to the traction belt 30 on the upstream side of the oven body 1, the belt feeding structure 11 and the belt collecting structure 21 are simultaneously activated, and the traction belt 30 moves in the second direction, thereby conveying the broken ends to the downstream side of the oven body 1. The operator connects the two breaks, thus resuming processing.

When the broken ends of the pole piece material belts do not need to be worn, the first driving structure 12 drives the belt conveying structure 11 to move, and meanwhile, the second driving structure 22 drives the belt collecting structure 21 to move, so that the traction belt 30 integrally moves to the side part of the oven body 1, and interference with a processing channel does not occur.

In the above structure, since the pole piece material belt is connected to only one traction belt 30, the situation that the pole piece material belt is pulled does not occur.

Preferably, the traction belt 30 is made of teflon, nylon, or the like.

Further, in this embodiment, the middle portion of the pole piece material belt in the width direction is connected to the traction belt 30. In order to support the broken end of the pole piece material belt, a supporting rod can be arranged on the traction belt 30, the supporting rod is vertically arranged with the traction belt 30, and the end of the pole piece material belt is connected with the supporting rod. Of course, it is also possible to provide the width of the traction belt 30 to be relatively wide, so that no support bar is necessary.

In the technical solution of this embodiment, the first direction and the second direction are vertically arranged. As described above, the first direction in the present embodiment is the width direction along the oven body 1, and the second direction is the length direction along the oven body 1.

As shown in fig. 2 and 3, in the technical solution of this example, the first driving structure 12 and the second driving structure 22 are both linear modules. Specifically, the linear module may be a linear motor, an electric cylinder, a screw nut mechanism, a belt mechanism, or the like, as long as the belt feeding structure 11 and the belt retracting structure 21 can be driven to move along a straight line.

As shown in fig. 2 and 3, in the technical solution of the present embodiment, the belt feeding structure 11 includes a first reel 111 and a first motor 112, the first motor 112 is disposed on a driving end of the first driving structure 12, and the first reel 111 is connected to a motor shaft of the first motor 112. The winding structure 21 includes a second reel 211 and a second motor 212, the second motor 212 is disposed on a driving end of the second driving structure 22, and the second reel 211 is connected with a motor shaft of the second motor 212.

Specifically, the traction belt 30 is wound on the first reel 111 and the second reel 211 at both ends, the first motor 112 can drive the first reel 111 to rotate and pay out the traction belt 30, and the second motor 212 can drive the second reel 211 to rotate and retract the traction belt 30, so that the traction belt 30 moves along the second direction.

As will be appreciated by those skilled in the art in connection with fig. 1, in the actual working process, only the second motor 212 may be operated, so that the second reel 211 serves as a driving wheel, the first reel 111 serves as a driven wheel, and the effect of driving the traction belt 30 to move may also be achieved. That is, it is also possible to provide only the second motor 212, and in this embodiment, an elastic return structure such as a torsion spring may be provided on the first reel 111, and when the second motor 212 is turned over, the first reel 111 may be reversely rotated by the elastic force, thereby retracting the traction belt 30.

Preferably, the device for threading the broken end of the material tape further comprises a control device connected with the first driving structure 12 and the second driving structure 22 to control the synchronous movement of the tape feeding structure 11 and the tape collecting structure 21.

Specifically, the control device enables the first driving structure 12 and the second driving structure 22 to synchronously stretch and retract, so that the belt feeding structure 11 and the belt collecting structure 21 are always positioned at the same position in the width direction of the oven body 1, and the traction belt 30 is ensured to extend along the second direction.

As shown in fig. 1, 4 and 5, an embodiment of a pole piece coating oven according to the present utility model includes an oven body 1 and the aforementioned threading device, where a first winding and unwinding mechanism 2 and a second winding and unwinding mechanism 3 of the threading device are respectively located on front and rear sides of the oven body 1. The oven body 1 includes a cabinet 100, a first baking structure 200, and a second baking structure 300. Wherein an inlet 101 and an outlet 102 are provided on the housing 100, and the traction belt 30 passes through the housing 100 through the inlet 101 and the outlet 102. The first and second roasting structures 200 and 300 are disposed at intervals in the up-down direction, and a tape passing gap 400 through which the electrode sheet passes is formed between the first and second roasting structures 200 and 300. Further, the traction belt 30 has a threading position and a avoidance position in the first direction, when the traction belt 30 is in the threading position, the traction belt 30 is positioned in the belt passing gap 400, and when the traction belt 30 is in the avoidance position, the traction belt 30 is positioned at the side of the first grilling structure 200 and the second grilling structure 300.

Further, the above-mentioned passing belt gap 400 also forms a processing channel of the pole piece.

In this embodiment, when the broken ends of the pole piece material belt need to be threaded, the first driving structure 12 drives the belt feeding structure 11 to move, and the second driving structure 22 drives the belt collecting structure 21 to move, so that the traction belt 30 integrally moves to the middle part of the belt passing gap 400 in the horizontal direction, that is, the threading position shown in fig. 4. The broken ends are connected (e.g., adhered, bound, etc.) to the traction belt 30 on the upstream side of the oven body 1, the belt feeding structure 11 and the belt collecting structure 21 are simultaneously activated, and the traction belt 30 moves in the second direction, thereby conveying the broken ends to the downstream side of the oven body 1. The operator connects the two breaks, thus resuming processing.

When the broken ends of the pole piece material belt do not need to be worn, the first driving structure 12 drives the belt feeding structure 11 to move, and meanwhile, the second driving structure 22 drives the belt collecting structure 21 to move, so that the traction belt 30 integrally moves to the side parts of the first baking structure 200 and the second baking structure 300, namely, the avoiding position shown in fig. 5, and therefore interference with the pole piece being processed in the belt passing gap 400 does not occur.

The utility model also provides a battery production line, and an embodiment of the battery production line comprises the pole piece coating oven.

In addition, those skilled in the art will understand that other material belt processing devices with processing channels in the battery production line can use the above belt threading device to thread the broken ends of the pole piece material belt.

It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. While still being apparent from variations or modifications that may be made by those skilled in the art are within the scope of the utility model.
