Description
Technical Field
[0001] The utility model relates to the technical field of lithium battery assembly, in particular to a shaping device for a busbar guide handle. Background Art
[0002] With the rapid development of the new energy industry, society's requirements for the energy density, safety performance, and fast charging performance of lithium-ion batteries have been further improved. As a highly recognized solution, large cylindrical batteries have ushered in a broad market space. Cylindrical batteries are mainly composed of a shell, a core, and a cover plate. Busbars are welded at both ends of the core. The busbars and the cover plate are usually connected by welding with a guide handle. During assembly, the guide handle needs to be bent, and the cover plate is covered on the end of the shell and connected by circumferential welding. At present, the test line mainly relies on manual bending, which may cause the shell cover to be misaligned, affecting the processing rhythm; at the same time, for some double-pass shells, the core assembly will slide to the other side during the bending of the guide handle, resulting in low yield and product consistency. Problems such as cannot be guaranteed. Although shaping equipment is used in large-scale production of the production line, the equipment is too large and occupies too many resources in the production area. Considering the overall cost and site layout, it is not suitable for installation and use of the test line. Utility Model Content
[0003] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by the present invention is: how to provide a shaping device with a relatively small structure, small occupation space, and conducive to improving the quality and processing rhythm of the guide handle bending process.
[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0005] A shaping device for a busbar guide handle, the guide handle having a first bending portion close to the busbar and a second bending portion close to the cover plate; characterized in that the shaping device comprises a positioning seat and a shaping bracket for vertically placing cylindrical batteries, the shaping bracket having an upper corner assembly and a lower corner assembly arranged obliquely opposite to each other, the upper corner assembly comprising a first linear telescopic mechanism arranged obliquely downward, a first bending handle for abutting the first bending portion is arranged on the telescopic end of the first linear telescopic mechanism, a limiting handle for blocking the cover plate is arranged at intervals and in parallel above the first bending handle, the spacing between the first bending handle and the limiting handle is greater than the distance between the first bending portion and the second bending portion, and less than the distance between the first bending portion and the center of the cover plate; the lower corner assembly comprises a second linear telescopic mechanism arranged obliquely upward, a second bending handle for abutting the second bending portion is arranged on the telescopic end of the second linear telescopic mechanism, and the projection of the second bending handle in the telescopic direction is located in the area between the first bending handle and the limiting handle.
[0006] With the above structure, during shaping, the cylindrical battery is placed vertically on the positioning seat, and the busbar and the cover plate are oriented toward the side where the lower corner assembly is located. The first bending handle and the limiting handle are first driven to move toward the busbar through the first linear telescopic mechanism. When the end of the first bending handle abuts against the first bending portion of the busbar, the second bending handle is driven to move toward the busbar through the second linear telescopic mechanism. At this time, the first bending portion is pressed by the first bending handle, and the second bending handle can push the busbar to fold upward along the first bending portion. Since the spacing between the first bending handle and the limiting handle is greater than the distance between the first bending portion and the second bending portion, and smaller than the distance between the first bending portion and the center of the cover plate, the cover plate will not be able to continue to fold upward when it hits the limiting handle. As the guide handle continues to fold upward under the push of the second bending handle, the cover plate is folded downward relative to the guide handle at the second bending portion of the guide handle, thereby completing the shaping of the guide handle. After that, after removing the first bending handle, the second bending handle and the limit handle, the cover plate only needs to be pressed down, so that the conductive handle can continue to be folded along the first bending part and the second bending part in the pre-bending state, so that the cover plate can be accurately covered on the shell. The above-mentioned shaping device has a relatively small structure and occupies a small space, which is conducive to improving the quality and processing rhythm of the guide handle bending process.
[0007] Furthermore, the bottom of the first bending handle and the top of the second bending handle both have horizontally arranged bending edges, the length of the bending edges is greater than the width of the guide handle; and the bending edges are perpendicular to the telescopic direction.
[0008] In this way, the first bending handle and the second bending handle abut against the guide handle through the bending edges, so that the guide handle can be accurately bent through the first bending portion and the second bending portion, thereby improving the bending accuracy.
[0009] Furthermore, the bottom of the first bending handle has a horizontally arranged lower pressing surface and a vertically arranged lower shaping surface, and the lower shaping surface is located on the side of the first bending handle facing the lower corner component and intersects with the lower pressing surface to form the bending edge.
[0010] In this way, the lower pressing surface and the lower shaping surface are arranged perpendicularly to each other, and an edge is formed at the junction of the two, which facilitates the bending of the guide handle along the edge. At the same time, through the vertically arranged lower shaping surface, the guide handle can be turned upward to a position perpendicular to the busbar.
[0011] Furthermore, the vertical spacing between the first bending handle and the limiting handle is equal to the distance between the first bending portion and the second bending portion; the top of the second bending handle has a horizontally arranged upper pressing surface and a vertically arranged upper shaping surface, and the upper shaping surface is located on the side of the second bending handle facing the upper corner component, and intersects with the upper pressing surface to form the bending edge.
[0012] In this way, the upper shaping surface and the upper pressing surface of the second bending handle can make the cover plate be in a horizontal state when the guide handle is in a vertical state.
[0013] Furthermore, the shaping bracket also has a horizontally arranged third linear telescopic mechanism, and the third linear telescopic mechanism is located above the lower corner assembly. The telescopic end of the third linear telescopic mechanism is connected to a horizontally arranged positioning plate, and the positioning plate is higher than the height of the top of the cylindrical battery to be assembled, and the height difference between the two is less than the distance between the first bending portion and the second bending portion.
[0014] In this way, the third linear telescopic mechanism drives the positioning plate toward the initially bent guide handle, so that the guide handle can be further bent toward the winding core to facilitate the subsequent closing of the cover plate.
[0015] Furthermore, the first linear telescopic mechanism, the second linear telescopic mechanism and the third linear telescopic mechanism are all telescopic cylinders.
[0016] Furthermore, the first bending handle, the limiting handle, the second bending handle and the end of the positioning plate facing the cylindrical battery to be assembled are all coated with PET insulating material.
[0017] Furthermore, the shaping bracket includes a vertically arranged upright plate, and the upper corner assembly and / or the lower corner assembly can be mounted on the upright plate in an adjustable manner up and down.
[0018] For cylindrical batteries of different diameters, the distances between the first bend and the second bend on the conductive handle are also different. By adjusting the height position of the upper corner assembly and / or the lower corner assembly, the distance between the two can be adjusted to be suitable for cylindrical batteries of different diameters or heights.
[0019] Furthermore, the vertical plate has mounting holes equidistantly arranged in the vertical direction, and the upper corner assembly and / or the lower corner assembly are mounted on the vertical plate by bolts.
[0020] Furthermore, the shaping bracket includes a horizontally arranged linear moving mechanism, the moving direction of the linear moving mechanism is perpendicular to the telescopic direction of the first linear telescopic mechanism and the second linear telescopic mechanism; the vertical plate is vertically arranged on the moving part of the linear moving mechanism.
[0021] In summary, the utility model has the advantages of relatively compact structure, small space occupation, and is beneficial to improving the quality and processing rhythm of the guide handle bending process. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The utility model is further described in detail below in conjunction with the embodiments.
[0025] When implementing: Figure 1 to Figure 3 As shown, a shaping device for a busbar guide handle is provided, the guide handle has a first bending portion close to the busbar and a second bending portion close to the cover plate; the shaping device comprises a positioning seat 1 for vertically placing cylindrical batteries and a shaping bracket 2, the shaping bracket 2 has an upper corner component 3 and a lower corner component 4 arranged obliquely opposite to each other, the upper corner component 3 comprises a first linear telescopic mechanism 31 arranged obliquely downward, a first bending handle 32 for abutting the first bending portion is provided on the telescopic end of the first linear telescopic mechanism 31, a limiting handle 33 for blocking the cover plate is provided above the first bending handle 32 in parallel and at intervals, the first bending handle 32 and the limiting handle 33 are arranged The spacing of the handles 33 is greater than the distance between the first bending portion and the second bending portion, and less than the distance between the first bending portion and the center of the cover plate; the lower corner assembly 4 includes a second linear telescopic mechanism 41 inclined upward, and a second bending handle 42 for abutting the second bending portion is provided on the telescopic end of the second linear telescopic mechanism 41, and the bottom of the first bending handle 32 and the top of the second bending handle 42 both have horizontally arranged bending edges, and the length of the bending edges is greater than the width of the guide handle; the bending edges are perpendicular to the telescopic direction; the projection of the second bending handle 42 in the telescopic direction is located in the area between the first bending handle 32 and the limiting handle 33.
[0026] In this embodiment, the bottom of the first bending handle 32 has a horizontally arranged lower pressing surface and a vertically arranged lower shaping surface, the lower shaping surface is located on the side of the first bending handle 32 facing the lower corner component 4, and intersects with the lower pressing surface to form the bending edge. The vertical spacing between the first bending handle 32 and the limiting handle 33 is equal to the distance between the first bending portion and the second bending portion; the top of the second bending handle 42 has a horizontally arranged upper pressing surface and a vertically arranged upper shaping surface, the upper shaping surface is located on the side of the second bending handle 42 facing the upper corner component 3, and intersects with the upper pressing surface to form the bending edge.
[0027] The shaping bracket 2 also has a third linear telescopic mechanism 51 arranged horizontally, and the third linear telescopic mechanism 51 is located above the lower corner assembly 4. The telescopic end of the third linear telescopic mechanism 51 is connected to a horizontally arranged positioning plate 52, and the positioning plate 52 is higher than the height of the top of the cylindrical battery to be assembled, and the height difference between the two is less than the distance between the first bending portion and the second bending portion. The first linear telescopic mechanism 31, the second linear telescopic mechanism 41 and the third linear telescopic mechanism 51 are all telescopic cylinders. The first bending handle 32, the limit handle 33, the second bending handle 42 and the positioning plate 52 are all coated with PET insulating material at one end facing the cylindrical battery to be assembled.
[0028] During shaping, the cylindrical battery is placed vertically on the positioning seat, and the busbar and the cover plate are facing the side where the lower corner assembly is located. The first bending handle and the limiting handle are driven to move toward the busbar through the first linear telescopic mechanism. When the end of the first bending handle abuts against the first bending portion of the busbar, the second bending handle is driven to move toward the busbar through the second linear telescopic mechanism. At this time, the first bending portion is pressed by the first bending handle, and the second bending handle can push the busbar to fold upward along the first bending portion. Since the spacing between the first bending handle and the limiting handle is greater than the distance between the first bending portion and the second bending portion, and smaller than the distance between the first bending portion and the center of the cover plate, the cover plate will not be able to continue to fold upward when it hits the limiting handle. As the guide handle continues to fold upward under the push of the second bending handle, the cover plate folds downward relative to the guide handle at the second bending portion of the guide handle, thereby completing the shaping of the guide handle. Figure 2 After the initial bending is completed, the first bending handle, the second bending handle and the limit handle are removed, and the positioning plate is driven toward the initially bent guide handle by the third linear telescopic mechanism, so that the guide handle can be further bent toward the winding core to facilitate the subsequent closing of the cover plate, as shown in FIG. Figure 3 After that, the cover plate only needs to be pressed down, so that the conductive handle can continue to be folded along the first bending portion and the second bending portion in the pre-bending state, so that the cover plate can be accurately covered on the shell. The above-mentioned shaping device has a relatively small structure and occupies a small space, which is conducive to improving the quality and processing rhythm of the bending process of the guide handle.

For cylindrical batteries of different diameters, the distance between the first bend and the second bend on the conductive handle is also different. By adjusting the height position of the upper corner assembly and / or the lower corner assembly, the distance between the two can be adjusted, so as to be suitable for cylindrical batteries of different diameters or heights.
