Description

A reel device

Technical Field

The utility model relates to the technical field of battery manufacturing, in particular to a winding device.

Background technique

The manufacturing process of lithium-ion batteries mainly consists of pulping, coating, roller slitting, laser cutting, lamination, assembly and formation. The winding method of the finished products of coating and roller slitting is usually to stick the finished products on a reel with double-sided tape and then rewind them.

There is a loading and splicing station when the coated finished roll is loaded on the roller slitting equipment and the roller slitting finished roll is loaded on the laser cutting equipment. Since the equipment needs a certain horizontal space to facilitate equipment maintenance, there is a distance of 2-5m between the loading end of the coated and roller slitting finished products collected on the roll and the splicing station. To ensure the smooth completion of the splicing, the operator often uses the finished product for traction, from the loading section to the splicing station.

When the next roll change and splicing operation is performed, the operator cuts and scraps the finished product from the splicing station to the feeding end, loads a new roll, and uses the new finished product to pull from the feeding end to the splicing station to complete the splicing. This method of using finished products with no quality problems for pulling causes waste of resources, resulting in a reduction in production efficiency, increased production costs, and reduced economic benefits. There is room for improvement.

For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

The embodiment of the utility model discloses a winding device which is applied in the battery manufacturing process.

Referring to Figure 1, in the embodiment of the utility model, the reel device includes a reel body 1, an elastic member 2 and a connecting belt 3. The interior of the reel body 1 has a accommodating space and one end of the accommodating space extends to the circumferential outer side of the reel body 1 to form an opening. The elastic member 2 is arranged in the accommodating space, and the connecting belt 3 is arranged in the accommodating space. The connecting belt 3 is connected to the elastic member 2 and the connecting belt 3 can be pulled out from the opening of the reel body 1.

The inventor of the utility model found that the existing tape splicing operation uses the finished product for traction, from the feeding section to the tape splicing station. When the next roll-changing tape splicing operation is performed, the finished product between the tape splicing station and the feeding end will be cut and scrapped, resulting in a waste of resources, a reduction in production efficiency, an increase in production costs, and a decrease in economic benefits. Based on this, in one embodiment of the utility model provided by the inventor, a accommodating space is provided in the reel body 1, and a connected elastic member 2 and a connecting belt 3 are provided in the accommodating space. The connecting belt 3 can be pulled out from the opening of the reel body 1, and the elastic member 2 has a reset pulling force on the connecting belt 3, which can pull the connecting belt 3 back to the inside of the reel body 1, similar to the structure of a tape measure.

During the production process, the finished product for coating, rolling and slitting can be connected to the connecting belt 3 to realize the winding operation of the finished product for coating, rolling and slitting.

When a new reel needs to be loaded with material and the connecting belt needs to be replaced, the pulling force is manually increased to pull the connecting belt 3, and the connecting belt 3 is passed from the loading end to the connecting station to complete the connecting operation; after the connecting operation is completed, the operator does not need to pull the connecting belt 3 anymore, and the elastic member 2 increases the pulling force to pull the connecting belt 3 back to the inside of the reel to complete the recovery of the connecting belt 3.

It should be noted that the specific operating principle is as follows: due to the operation of changing the reel and splicing the tape, there will be two reel devices. In order to better understand the operating process of the self-contained traction structure of the utility model, a new reel and an old reel are used as examples.

When the finished product on the old reel is unwound and the splicing belt needs to be replaced, the tail of the finished product on the old reel will be connected to the connecting belt 3. At this moment, the head of the finished product on the new reel can be connected to the connecting belt 3 of the old reel device. At this moment, the connecting belt 3 on the old reel can be manually pulled from the feeding end to the splicing station, and the finished product on the new reel will also be driven synchronously to complete the splicing operation. After the splicing operation is completed, the connecting belt 3 on the old reel can be pulled back to the inside of the reel through the reset elastic belt of the elastic member 2 to complete the recovery of the connecting belt 3.

It can be seen that the reel device has its own traction function and does not need to use finished products for traction, thus reducing unnecessary waste of resources and improving production efficiency and economic benefits.

In one embodiment, the elastic member 2 may be a spring, a tension spring or other workpiece with elastic return capability.

Referring to Fig. 1, in one embodiment of the utility model, the connecting belt 3 is provided with an adhesive member for adhering the finished product. In this way, the finished product for coating, rolling and slitting can be adhered to the connecting belt 3 through the adhesive member to facilitate the winding operation or other battery manufacturing operations.

In one embodiment, the bonding member may be a tape, an adhesive or other workpiece with an adhesion effect, such as a double-sided tape.

Referring to Fig. 1, in one embodiment of the utility model, a baffle plate 4 is provided on the circumferential outer side of the reel body 1 at the opening, a gap is reserved between the baffle plate 4 and the opening for the connecting belt 3 to be pulled out, and the connecting belt 3 is provided with a clamping member 5 for clamping with the gap. In this way, when the elastic member 2 pulls back the connecting belt 3, the clamping member 5 will be clamped in the gap between the baffle plate 4 and the circumferential outer side of the reel body 1, thereby preventing the connecting belt 3 from being completely brought back to the inside of the reel body 1, so as to facilitate the subsequent pulling of the connecting belt 3 and improve the convenience of operation.

Referring to Fig. 1, in one embodiment of the utility model, the clamping member 5 is arranged at one end of the connecting belt 3 away from the elastic member 2 and the end is set as the head. In this way, when the elastic member 2 pulls back the connecting belt 3, the clamping member 5 will be stuck in the gap between the baffle 4 and the circumferential outer side of the reel body 1, which can not only prevent the connecting belt 3 from being completely brought back to the inside of the reel body 1, but also prevent the connecting belt 3 from being exposed to the circumferential outer side of the reel body 1 too much, which can effectively prevent the connecting belt 3 from being damaged during transportation or operation, and better protect the connecting belt 3.

Referring to Fig. 1, in one embodiment of the utility model, two clamping parts 5 are provided, and the two clamping parts 5 are provided one by one at both sides of the square of the head of the connecting belt 3 along its width. In this way, the middle area of the connecting belt 3 can be kept as empty as possible, so that the middle area of the connecting belt 3 can be used to adhere the finished product for coating, rolling and slitting, so as to prevent the clamping parts 5 from affecting the finished product for coating, rolling and slitting.

Referring to Fig. 1, in an embodiment of the utility model, two baffles 4 are provided, and the two baffles 4 are provided one by one on both sides of the reel body 1 along its width direction; two gaps are reserved one by one between the two baffles 4 and the opening, and two clamping members 5 are clamped one by one. In this way, the two sides of the connecting belt 3 are clamped on the two baffles 4 through the two clamping members 5, respectively, to form a stable clamping state, and will not tilt to any side, so as to prevent the finished product connected to the connecting belt 3 from tilting.

In one embodiment, the clamping member 5 is a clamping bead which is spherical and can reduce the wear on the circumferential outer side of the reel body 1 and better protect the reel body 1 .

In one embodiment, the diameter of the bead is greater than the spacing between the baffle plate 4 and the opening. In this way, the bead can be stuck in the gap between the baffle plate 4 and the opening to prevent the connecting belt 3 from being completely brought back to the inside of the reel body 1.

Referring to Fig. 1, in one embodiment of the utility model, two elastic members 2 are provided, and the two elastic members 2 are provided one by one on both sides of the connecting belt 3 along its own width direction. In this way, when the elastic member 2 pulls back the connecting belt 3, it will simultaneously pull both sides of the connecting belt 3 along its own direction, so as to prevent the connecting belt 3 from tilting during the pulling, and to prevent the finished product connected to the connecting belt 3 from tilting as well.

In one embodiment of the present invention, the thickness d of the connecting belt 3 itself is in the range of 10 μm ≤ d ≤ 25 μm. This arrangement can ensure that the connecting belt 3 itself has sufficient structural strength and will not be damaged when being pulled, and can also avoid protruding too much from the circumferential outer side of the reel body 1, ensuring that the finished product can be rolled up normally.

In some embodiments, the thickness d of the connecting tape 3 itself can be 10 μm, 12 μm, 14 μm, 16 μm, 18 μm, 20 μm, 22 μm, 24 μm or 25 μm. Of course, in other embodiments, the thickness d of the connecting tape 3 itself can also be other values within the range of 10 μm≤d≤25 μm.

The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
