Description

Technical Field

[0001] This invention relates to a limiting device and a limiting method for battery production. Background Technology

[0002] Tubular batteries include a tubular casing. During the production process, such as when cutting the tubular casing, a limiting device is needed to restrict and position the tubular casing to facilitate cutting. However, the tubular casing is prone to rotation due to force during positioning, resulting in poor positioning effect. Summary of the Invention

[0003] Therefore, it is necessary to provide a limiting device and a limiting method for battery production.

[0004] In a first aspect, the present invention provides a limiting device for battery production, comprising a mounting plate, a limiting component, and two positioning components. The mounting plate is recessed with an arc-shaped positioning recess for receiving a tubular housing. The limiting component is disposed at one end of the mounting plate for blocking the end of the tubular housing. The two positioning components are disposed on the mounting plate and are respectively located on opposite sides of the arc-shaped positioning recess. Each positioning component includes a positioning cylinder and an arc-shaped positioning plate. The arc-shaped positioning plate is connected to the positioning cylinder and is used to abut against the tubular housing. The top edge of the arc-shaped positioning plate is provided with a plurality of arc-shaped ribs, each of which is used to engage with a plurality of annular grooves on the circumferential surface of the tubular housing.

[0005] In one embodiment, the tubular shell is cylindrical with helical ribs protruding from its circumference, the helical ribs forming multiple loops around it.

[0006] In one embodiment, an annular groove is formed between every two adjacent turns of the spiral ridge, and multiple annular grooves on the circumferential surface of the tubular housing are connected to form a spiral groove.

[0007] In one embodiment, the plurality of arc-shaped ribs are spaced apart from each other along the length direction of the arc-shaped positioning plate.

[0008] In one embodiment, the bottom surface of the arc-shaped rib is a concave arc surface, which matches the bottom surface of the annular groove.

[0009] In one embodiment, each of the positioning components further includes a drive shaft connected to the output shaft of the positioning cylinder, and the arc-shaped positioning plate is mounted on the drive shaft.

[0010] In one embodiment, the positioning cylinder is mounted on the end of the mounting plate away from the limiting component, and the length direction of the arc-shaped positioning plate is parallel to the length direction of the drive shaft.

[0011] In one embodiment, a wedge-shaped edge is formed on the top side of the arc-shaped positioning plate, and the plurality of arc-shaped ribs are disposed at the bottom of the wedge-shaped edge.

[0012] In one embodiment, the length direction of the arc-shaped rib is perpendicular to the length direction of the wedge-shaped edge, the thickness of the arc-shaped positioning plate is less than the diameter of the drive shaft, and the bottom surface of the mounting plate is a plane.

[0013] Secondly, the present invention also provides a limiting method for a limiting device used in battery production, wherein a tubular housing is conveyed to an arc-shaped positioning recess on the mounting plate, and the end of the tubular housing is abutted against the limiting component. The positioning cylinders of the two positioning components drive the corresponding arc-shaped positioning plates to cover the tubular housing. Multiple arc-shaped ribs on the arc-shaped positioning plates are engaged in multiple annular grooves on the tubular housing, thereby achieving the positioning of the tubular housing.

[0014] In use, the battery production limiting device transports the tubular housing to the arc-shaped positioning recess on the mounting plate, and the end of the tubular housing abuts against the limiting component to achieve positioning of the tubular housing. The positioning cylinders of the two positioning components drive corresponding arc-shaped positioning plates to cover the tubular housing. Multiple arc-shaped ribs on the arc-shaped positioning plates engage with multiple annular grooves on the tubular housing, thereby achieving positioning of the tubular housing and facilitating cutting of its end. Because the arc-shaped positioning plate has multiple arc-shaped ribs that engage with the multiple annular grooves on the tubular housing, the line contact between the arc-shaped positioning plate and the tubular housing is changed to multi-point contact by the multiple arc-shaped ribs. This prevents the tubular housing from rotating due to force, improves the positioning stability of the tubular housing, and results in a better positioning effect. Attached Figure Description

Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] This invention relates to a limiting device for battery production. For example, the limiting device includes a mounting plate, a limiting component, and two positioning components. The mounting plate has an arc-shaped positioning recess for receiving a tubular housing. For example, the limiting component is located at one end of the mounting plate to stop the end of the tubular housing. The two positioning components are both located on the mounting plate and on opposite sides of the arc-shaped positioning recess. For example, each positioning component includes a positioning cylinder and an arc-shaped positioning plate. The arc-shaped positioning plate is connected to the positioning cylinder and abuts against the tubular housing. The top edge of the arc-shaped positioning plate has multiple arc-shaped ribs. For example, each of the multiple arc-shaped ribs is used to engage with multiple annular grooves on the circumferential surface of the tubular housing.

[0022] Please see Figure 1 and Figure 2A limiting device 100 for battery production includes a mounting plate 10, a limiting component 20, and two positioning components 30. The mounting plate has an arc-shaped positioning recess 11 for receiving a tubular housing. The limiting component is disposed at one end of the mounting plate for blocking the end of the tubular housing. The two positioning components are disposed on the mounting plate and are respectively located on opposite sides of the arc-shaped positioning recess. Each positioning component includes a positioning cylinder 31 and an arc-shaped positioning plate 32. The arc-shaped positioning plate is connected to the positioning cylinder and is used to abut against the tubular housing. The top edge of the arc-shaped positioning plate has a plurality of arc-shaped ribs (not shown in the figure), which are respectively used to engage with a plurality of annular grooves on the circumferential surface of the tubular housing.

[0023] In use, the battery production limiting device transports the tubular housing to the arc-shaped positioning recess on the mounting plate, and the end of the tubular housing abuts against the limiting component to achieve positioning of the tubular housing. The positioning cylinders of the two positioning components drive corresponding arc-shaped positioning plates to cover the tubular housing. Multiple arc-shaped ribs on the arc-shaped positioning plates engage with multiple annular grooves on the tubular housing, thereby achieving positioning of the tubular housing and facilitating cutting of its end. Because the arc-shaped positioning plate has multiple arc-shaped ribs that engage with the multiple annular grooves on the tubular housing, the line contact between the arc-shaped positioning plate and the tubular housing is changed to multi-point contact by the multiple arc-shaped ribs. This prevents the tubular housing from rotating due to force, improves the positioning stability of the tubular housing, and results in a better positioning effect.

[0024] For example, to facilitate the rotation of the arc-shaped positioning plate, the tubular housing is cylindrical with helical ribs protruding from its circumference, forming multiple turns. An annular groove is formed between each pair of adjacent turns of the helical ribs, and the multiple annular grooves on the circumference of the tubular housing connect to form a helical groove. The multiple arc-shaped ribs are spaced apart along the length of the arc-shaped positioning plate. The bottom surface of each arc-shaped rib is concave, and the concave surface matches the bottom surface of the annular groove. Each positioning assembly also includes a drive shaft 33, which is connected to the output shaft of the positioning cylinder, and the arc-shaped positioning plate is mounted on the drive shaft. The positioning cylinder is mounted on the end of the mounting plate away from the limiting assembly, and the length direction of the arc-shaped positioning plate is parallel to the length direction of the drive shaft. A wedge-shaped edge 325 is formed on one side of the top of the arc-shaped positioning plate, and the multiple arc-shaped ribs are disposed at the bottom of the wedge-shaped edge. The length direction of the arc-shaped ribs is perpendicular to the length direction of the wedge-shaped edge. The thickness of the arc-shaped positioning plate is less than the diameter of the drive shaft, and the bottom surface of the mounting plate is flat. By incorporating the positioning cylinder, the drive shaft can be easily driven to rotate the arc-shaped positioning plate. Furthermore, by aligning the multiple arc-shaped ribs perpendicular to the wedge-shaped edge, the multiple arc-shaped ribs can easily engage with the multiple annular grooves, thereby improving the positioning effect on the tubular housing.

[0025] Please refer to the following: Figure 3 The wedge-shaped edge of the arc-shaped positioning plate is located on the side away from the drive shaft. A flexible positioning strip (not shown) is formed on the side of the wedge-shaped edge away from the drive shaft. The bottom surface of the flexible positioning strip is provided with adhesive for removable bonding to the helical ribs of the tubular housing to improve the positioning effect. For example, to further prevent the rotation of the tubular housing, each positioning component also includes a flexible plate 35. One side of the flexible plate is connected to the edge of the arc-shaped positioning recess, and the other side of the flexible plate is connected to the wedge-shaped edge and located at the end of the plurality of arc-shaped ribs away from the flexible positioning strip. The side of the flexible plate opposite to the drive shaft is provided with a plurality of removable adhesive layers. When positioning the tubular housing, the two drive cylinders respectively drive the two arc-shaped positioning plates to move towards each other to close onto the tubular housing. The wedge-shaped edges of the two arc-shaped positioning plates abut against the top of the tubular shell, while the two flexible plates are tightly attached to the opposite sides of the tubular shell and held open by the tubular shell, thus achieving a tight fit. The removable adhesive layer of the flexible plates adheres to the periphery of the tubular shell, thereby preventing the tubular shell from rotating. After cutting and releasing the tubular shell, if one of the removable adhesive layers on the surface becomes contaminated, the surface removable adhesive layer can be peeled off to allow a new removable adhesive layer to adhere to the next tubular shell.

[0026] For example, to facilitate guiding the tubular housing, a retaining groove 15 is recessed at the end of the mounting plate away from the limiting component, and the extending direction of the retaining groove is perpendicular to the length direction of the mounting plate. The arc-shaped positioning recess is located in the middle of the retaining groove. Each positioning component also includes a guide plate 36, which includes a rigid plate 361, a pivot 362, and an elastic plate 363. The pivot is disposed on one side of the arc-shaped positioning recess and fixed to the mounting plate. The rigid plate and the elastic plate are respectively connected to opposite sides of the pivot. The side of the elastic plate away from the pivot is connected to one end of the flexible plate. A retaining portion protrudes from the bottom of the rigid plate, and the retaining portion is slidably engaged in the retaining groove. The distance between the guide plates of the two positioning components gradually increases in the direction away from the limiting component, for guiding the tubular housing. The distance between the two pivots is equal to the outer diameter of the tubular housing. The two guide plates are used to guide the tubular housing into the space between the two flexible plates.

[0027] Each positioning component has a gear section 338 at the end of its drive shaft away from the positioning cylinder. A positioning frame 339 is mounted on the gear section, and a positioning groove 3395 is provided on the positioning frame. The two gear sections rotate under the drive shaft, causing the positioning frames on them to engage with each other, so that the two positioning grooves abut against each other, allowing the cutting blade to move downwards from the two positioning grooves for cutting. The limiting component includes two transmission gears 21, two limiting gears 22, and two limiting frames 23. The two transmission gears are mounted on the end of the mounting plate, located between the two gear sections, and mesh with each other. The outer diameter of the transmission gears is larger than the outer diameter of the gear sections. The two limiting gears are located on opposite sides of the arc-shaped positioning recess, between the two transmission gears, and mesh with each other. The two limiting frames are respectively located at the ends of the two limiting gears. The limiting bracket is located at the end furthest from the positioning bracket. When the drive shaft drives the gear section to rotate, forcing the two positioning brackets to cooperate for positioning and cutting, the two transmission gears are driven by the two gear sections to rotate, which in turn drives the two limiting gears to rotate. The two limiting gears drive the two limiting brackets to move towards each other and abut against each other, thereby using the two limiting brackets to limit the end of the tubular shell. When the two positioning cylinders drive the two drive shafts to rotate in opposite directions, the two arc-shaped positioning plates move away from each other to release the tubular shell and cause the two flexible positioning strips and the two flexible plates to move away from the tubular shell. At this time, the two limiting brackets and the two limiting brackets are also moving away from each other to facilitate the passage of the tubular shell. Through the above arrangement, the positioning of the tubular shell is more convenient. The two guide plates can guide the tubular shell into the arc-shaped positioning recess. The two elastic plates can elastically deform relative to the pivot to tightly clamp the tubular shell and improve the clamping and positioning effect.

[0028] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0029] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
