At present, with the continuous expansion of the application field of power batteries, the market demand is continuously expanding, which also puts higher requirements on the assembly cycle and the assembly yield of the batteries.

The inventor notices that in the traditional steel belt process, when two side edges of the steel belt are stressed to generate elastic deformation, the unstressed side edge also generates structural deformation, so that the expanded size and the preset size have certain deviation more or less. If size after the deviation can't with electric core module 300 adaptation when, the blue membrane of electric core can seriously fish tail on at least one side of steel band, lead to the battery after the equipment can't satisfy the product control requirement, if light then the maintenance of doing over again, if heavy then directly scrap, seriously influence battery production efficiency and yield.

Based on the above consideration, in order to solve the problem that the blue film of the battery cell is easily scratched during assembly, the inventor conducted extensive research and designed a taping mechanism 100, please refer to fig. 1, wherein at least a reference 111, a first positioning member 112 and a second positioning member 113 are disposed during positioning, and the first positioning member 112 and the second positioning member 113 are disposed opposite to each other. Meanwhile, the first positioning member 112 and the second positioning member 113 are driven to move away from or towards each other by cooperating with the at least one driver 120, and the at least one lifter 130 is configured to drive the whole positioning structure 110 to move up and down.

In the strap mechanism 100 thus designed, at least three sides of the fastening strap 400 are effectively positioned when stretched; meanwhile, one side of the reference 111 is used as a positioning basis, so that the reference 111 is always used as the positioning basis when the fastening belt 400 is unfolded, the phenomenon that the blue film of the battery cell is easily scratched due to large deformation of the unstressed side of the fastening belt 400 is effectively avoided, the problem that the blue film of the battery cell is easily scratched during assembly is effectively solved, and the assembly yield and the assembly efficiency of the battery are improved.

The application discloses set of belting mechanism 100 is applicable to the steel band of electric core module 300 and cup joints, for example: the lower steel belt is automatically sleeved outside the battery cell module 300 through the belt sleeving mechanism 100, and the upper steel belt can also be automatically sleeved outside the battery cell module 300 and the like. Of course, the taping mechanism 100 disclosed in the present application is not limited to the above-described devices, and can also be applied to all devices requiring taping, such as: aluminum ingot binding equipment, carton packing equipment and the like.

The sleeve belt mechanism 100 disclosed in the embodiment of the present application can be used in cooperation with the battery extrusion mechanism 200, and can also be used in cooperation with other ejection mechanisms. If the taping mechanism 100 is used in conjunction with the extrusion mechanism 200, referring to fig. 1 and fig. 2, before the jacking device 130 drives the expanded fastening tape 400 to be sleeved outside the battery cell module 300, the battery cell module 300 can be extruded by the extrusion mechanism 200 to be compressed and deformed. When the jacking device 130 sleeves the expanded fastening belt 400 outside the battery cell module 300, the retraction and extrusion mechanism 200 releases force, so that the battery cell module 300 rebounds and is tensioned on the fastening belt 400. If the sleeve belt mechanism 100 is matched with the ejection mechanism, the jacking device 130 lifts the expanded fastening belt 400 to be sleeved outside the battery cell module 300. At this time, the fastening band 400 after being spread can be directly slid onto the battery cell module 300 through the ejection mechanism.

The present embodiment provides a battery assembling system using the strap mechanism 100 for automatic sleeving, please refer to fig. 2 and fig. 3, which includes the strap mechanism 100 and the pressing mechanism 200. In this embodiment, the structure of the pressing mechanism 200 has multiple designs, and it is only necessary to press the cell module 300 formed by combining at least two cells 310 arranged side by side, for example: the extruding mechanism 200 can be designed to be, but not limited to, a combination structure of a cylinder and a push block 240, a combination structure of an electric cylinder and a push block 240, a combination structure of a motor, a screw rod and a push block 240, and the like.

According to some embodiments of the present application, a strap mechanism 100 is provided. Referring to fig. 1 and 4, the strap threading mechanism 100 includes a positioning structure 110, a driver 120 and a lifter 130. The positioning structure 110 includes a base 111, and a first positioning element 112 and a second positioning element 113 disposed opposite to each other. The first positioning member 112 and the second positioning member 113 are used for positioning and matching with the first edge 410 and the second edge 420 of the fastening strip 400. The datum 111 is configured to be positioned in engagement with a third edge 430 of the fastening strip 400 that is connected between the first edge 410 and the second edge 420. The driver 120 is used for driving the first positioning element 112 and the second positioning element 113 to move away from or towards each other. The lifter 130 is configured to drive the positioning structure 110 to move up and down relative to the battery cell module 300.

"the driver 120 drives the first positioning element 112 and the second positioning element 113 to move away from or towards each other" should be understood as: when the first positioning element 112 and the second positioning element 113 are driven to move, they may share one driver 120, or may be driven by one driver 120. When the first positioning member 112 and the second positioning member 113 share one actuator 120, the actuator 120 can be designed as, but not limited to, a motor and screw assembly, a telescopic device, two hinged stay bar assemblies, and the like. The telescopic device can be, but not limited to, an air cylinder, a hydraulic cylinder, an electric cylinder, and the like. For example: when the driver 120 is a combined structure of a motor and a screw rod, the first positioning element 112 and the second positioning element 113 are both screwed on the screw rod, and the screw threads of the first positioning element 112 and the second positioning element 113 are opposite in rotation direction, and when the motor drives the screw rod to rotate, the first positioning element 112 and the second positioning element 113 are away from each other or move towards each other under the screw thread transmission.

The term "positioning fit" means that when the first edge 410, the second edge 420 and the third edge 430 of the fastening strip 400 respectively act on the first positioning member 112, the second positioning member 113 and the reference 111, the first edge 410 and the first positioning member 112, the second edge 420 and the second positioning member 113, and the third edge 430 and the reference 111 are respectively tightly combined during the unfolding process of the fastening strip 400, and no relative movement is generated. For example: the first positioning piece 112, the second positioning piece 113 and the datum 111 are provided with grooves for clamping the edges of the fastening belt 400; alternatively, protrusions are provided on the first positioning member 112, the second positioning member 113 and the reference 111 to hook the inner sides of the respective bands of the fastening band 400, respectively; further alternatively, fixing members such as: magnetic equipment, buckle structure, locating pin etc.. In addition, when positioning, a manual mode can be adopted, and an automatic mode can also be adopted, such as: the fastening band 400 is positioned on the positioning structure 110 by a robot. Wherein the first side 410 is opposite to the second side 420, and the third side 430 is opposite to the fourth side 440.

The fastening belt 400 is not limited to a steel belt, but may be a belt made of other materials, that is, the fastening belt 400 capable of fastening the battery cell module 300 can perform automatic belt sleeving operation by using the belt sleeving mechanism 100 of the embodiment. In addition, the fourth side 440 of the fastening strip 400 may be positioned during taping as well as not. When the fourth side 440 of the fastening band 400 is not positioned, the positioning structure 110 is not provided with a corresponding structure at a position corresponding to the fourth side 440, so that the fourth side 440 of the fastening band 400 is in a free state, which enables the fastening band 400 to be compatible with a plurality of lengths, and the application range of the fastening band 400 is expanded.

Positioning the third side 430 of the fastening band 400 on the datum 111 during the battery assembly process as the datum 111 end where the fastening band 400 is positioned; and then the first edge 410 and the second edge 420 which are oppositely arranged on the fastening belt 400 are respectively and correspondingly positioned on the first positioning part 112 and the second positioning part 113, so that at least three edges of the fastening belt 400 are effectively positioned, and the fastening belt 400 is ensured to be accurately positioned. When the at least one driver 120 drives the first positioning element 112 and the second positioning element 113 to move away from each other, the first edge 410 and the second edge 420 are respectively forced to move away from each other to be elastically deformed, so that the interior of the fastening band 400 is expanded; after the battery cell module 300 is unfolded, the positioning structure 110 is driven to integrally ascend through the at least one jacking device 130, so that the unfolded fastening belt 400 is sleeved outside the battery cell module 300. Because the fastening belt 400 always takes the reference 111 as a positioning basis when being unfolded, the phenomenon that the blue film of the battery cell is easily scratched due to large deformation of the unstressed side of the fastening belt 400 can be effectively avoided when the fastening belt is unfolded, so that accurate and stable strap covering is realized, and the assembly yield and efficiency of the battery are improved.

Similarly, the number of the second drivers 122 and the second positioning elements 113 may be configured to correspond to each other one by one; a one-to-many configuration is also possible. The first actuator 121 and the second actuator 122 may be, but not limited to, an air cylinder, an electric cylinder, a hydraulic cylinder, etc.

The driver 120 is divided into at least a first driver 121 and a second driver 122 so that the first positioning member 112 and the second positioning member 113 are driven individually by the first driver 121 and the second driver 122, respectively. So design for first setting element 112 and second setting element 113's motion is steady, thereby guarantees fastening area 400 struts the action more stable, is favorable to promoting the assembly quality of battery.

According to some embodiments of the present application, optionally, referring to fig. 1 and 5, the positioning structure 110 further includes a first beam 140 with a first driver 121, and a second beam 150 with a second driver 122.
