Abstract
Description
Technical Field
[0001] This utility model belongs to the field of battery production technology, specifically relating to a welding and positioning mechanism for irregularly shaped batteries. Background Technology
[0002] Currently, some small wearable devices use steel-cased batteries with welded mounting brackets. These batteries can be directly installed inside the device, saving installation space. However, in some small wearable devices with irregular installation spaces (such as smartwatches), irregularly shaped steel-cased batteries are used to accommodate the space. Conventional steel-cased batteries are typically rectangular, with four straight sidewalls. The mounting bracket is usually welded to two of these opposite sidewalls. Irregularly shaped steel-cased batteries have a beveled sidewall at at least one corner, giving them a polygonal shape. One mounting bracket is then welded to this beveled sidewall. Before welding the mounting bracket to the beveled sidewall, a visual positioning component captures the reference edge position information of the beveled sidewall from directly above the battery. This information is then used to instruct the welding mechanism to weld the mounting bracket to the beveled sidewall. However, due to certain special production requirements, the top of the sloping sidewall of the steel-cased battery has an extension that extends outward in the horizontal direction. This extension will block the reference edge of the sloping sidewall, causing the visual positioning component to be unable to capture the position information of the reference edge of the sloping sidewall, thus making it impossible to achieve accurate positioning before welding.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.
[0035] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0036] Example 1
[0037] refer to Figures 1 to 5The irregular battery welding positioning mechanism provided in this embodiment includes a positioning and fixing component 1, an inclined surface reference positioning component 2 disposed on one side of the positioning and fixing component 1, and a visual positioning component 3 disposed above the positioning and fixing component 1. The positioning and fixing component 1 is used to position and fix the main body of the irregular battery, and the inclined surface reference positioning component 2 is used to cooperate with the visual positioning component 3 to complete the positioning of the inclined sidewall of the irregular battery.
[0038] The inclined plane reference positioning assembly 2 includes a positioning reference block 21, a first driving member 22 for driving the positioning reference block 21 to move horizontally, and a second driving member 23 for driving the positioning reference block 21 and the first driving member 22 to move vertically. Both the first driving member 22 and the second driving member 23 can be driving cylinders. A positioning reference portion 211 is formed on the positioning reference block 21. Under the driving action of the first driving member 22 and the second driving member 23, the positioning reference block 21 can approach the steel-cased battery and abut against the inclined sidewall of the steel-cased battery. The positioning reference portion 211 can serve as a positioning reference for the inclined sidewall of the steel-cased battery for visual capture by the vision positioning assembly 3. Understandably, since the sidewall of the positioning reference block 21 is completely attached to the inclined sidewall of the steel-shell battery, and the relative position of the positioning reference part 211 and the sidewall of the positioning reference block 21 is fixed, that is, the relative position of the positioning reference part 211 and the inclined sidewall of the steel-shell battery is fixed, the visual positioning component 3 can accurately calculate the position information of the inclined sidewall of the steel-shell battery by capturing the position information of the positioning reference part 211, thereby achieving precise positioning of the inclined sidewall of the steel-shell battery.
[0039] The bottom view of the irregularly shaped battery in this embodiment is as follows: Figure 4 As shown, the outer contour of the irregularly shaped battery is mainly formed by a first straight sidewall 100, a first inclined sidewall 200, a second straight sidewall 300, a second inclined sidewall 400, a third straight sidewall 500, and a fourth straight sidewall 600 connected in sequence. In this embodiment, the positioning reference block 21 is used to abut against the first inclined sidewall 200. It can be understood that when the irregularly shaped battery is loaded onto the positioning and fixing assembly 1, the first inclined sidewall 200 is located at the edge of the positioning and fixing assembly 1, thereby allowing the positioning reference block 21 to abut against it.
[0040] In one embodiment, the positioning reference part 211 is a raised strip structure formed at the top edge of the positioning reference block 21. The positioning reference part 211 includes a first sidewall 2111 and a second sidewall 2112 that are parallel to each other. The first sidewall 2111 is flush with the sidewall of the positioning reference block 21 near the steel-cased battery. The first sidewall 2111 is used to abut against the sloping sidewall of the irregularly shaped battery. The top edge of the second sidewall 2112 serves as the reference edge of the sloping sidewall for visual capture by the visual positioning component 3. Since the first sidewall 2111 and the second sidewall 2112 are parallel and the distance between them is fixed, the visual positioning component 3 can calculate the position information of the sloping sidewall of the irregularly shaped battery by capturing the position information of the top edge of the second sidewall 2112 and combining it with the distance parameter between the top edges of the first sidewall 2111 and the second sidewall 2112, thereby achieving accurate positioning of the sloping sidewall.
[0041] As a further optimization, since there may be certain deviations in the tilt angle of the inclined sidewalls between different shaped batteries, in order to enable the positioning reference block 21 to adapt to inclined sidewalls with different tilt angles, the inclined reference positioning assembly 2 also includes a connector 24 disposed at the driving end of the first driving member 22. The end of the connector 24 is provided with a rotating shaft 25, a first floating member 26 and a second floating member 27. The first floating member 26 and the second floating member 27 are respectively located on opposite sides of the rotating shaft 25. The positioning reference block 21 is rotatably connected to the connector 24 through the rotating shaft 25, and the two ends of the positioning reference block 21 are respectively connected to the first floating member 26 and the second floating member 27.
[0042] It is understood that the positioning reference block 21 can rotate and swing horizontally around the rotation axis 25. Since the left and right ends of the positioning reference block 21 are respectively connected to the connecting member 24 by the first floating member 26 and the second floating member 27, the first floating member 26 and the second floating member 27 can restrain the swinging behavior of the positioning reference block 21. When the positioning reference block 21 abuts against the inclined sidewall of the irregularly shaped battery, the positioning reference block 21 will swing slightly in accordance with the inclination angle of the inclined sidewall, and maintain a fixed swing angle under the restraint of the first floating member 26 and the second floating member 27. In this embodiment, the first floating member 26 and the second floating member 27 are both springs.
[0043] In some embodiments, the visual positioning component 3 includes a positioning CCD 31 and a supplementary light source 32. The supplementary light source 32 is disposed below the positioning CCD 31. The supplementary light source 32 can improve the visual brightness and clarity of the positioning CCD 31 to ensure that the positioning CCD 31 can accurately capture the position information of the positioning reference unit 211.
[0044] Example 2
[0045] As a further optimization of Example 1, in Figures 1 to 5Based on, refer to Figures 6 to 8 The positioning and fixing component 1 includes a positioning platform 11, a first pushing member 12 and a second pushing member 13. The inclined plane reference positioning component 2, the first pushing member 12 and the second pushing member 13 are all arranged on the outer periphery of the positioning platform 11. A first limiting block 14 and a second limiting block 15 are respectively arranged on the adjacent sides of the positioning platform 11. The first pushing member 12 is used to push the irregularly shaped battery to abut against the first limiting block 14, and the second pushing member 13 is used to push the irregularly shaped battery to abut against the second limiting block 15. The pushing direction of the first pushing member 12 is perpendicular to the pushing direction of the second pushing member 13.
[0046] Understandably, when the irregularly shaped battery is loaded onto the positioning platform 11, the fourth straight sidewall 600 is located on one side of the first limiting block 14, the first straight sidewall 100 is located on one side of the second limiting block 15, and the first inclined sidewall 200 is located on the side close to the inclined reference positioning component 2. Then, the first pushing member 12 will abut against the second straight sidewall 300 and push the irregularly shaped battery to move, so that the fourth straight sidewall 600 abuts against the first limiting block 14. Then, the second pushing member 13 will abut against the third straight sidewall 500 and push the irregularly shaped battery to move, so that the first straight sidewall 100 abuts against the second limiting block 15. This achieves the positioning and fixing of the main body of the irregularly shaped battery. Then, the inclined reference positioning component 2 and the visual positioning component 3 will position the first inclined sidewall 200.
[0047] In some embodiments, the irregularly shaped battery welding and positioning mechanism further includes a pressing and fixing assembly 4. The pressing and fixing assembly 4 includes a pressing member 41 and a third driving member 42 for driving the pressing member 41 to move vertically. The third driving member 42 can be a driving cylinder. The pressing member 41 is located above the positioning platform 11, and the third driving member 42 can be located above or below the positioning platform 11, preferably below it. By setting the pressing and fixing assembly 4 to further fix the irregularly shaped battery, the accuracy of positioning the inclined sidewall of the irregularly shaped battery is further improved.
[0048] Example 3
[0049] As a further optimization of Example 2, in Figures 1 to 8 Based on, refer to Figure 9 The irregular battery welding and positioning mechanism also includes a first driving component 5 for driving the positioning and fixing component 1 to move in the horizontal direction, thereby realizing the feeding or unloading of irregular batteries.
[0050] In some embodiments, the irregularly shaped battery welding and positioning mechanism further includes a mounting base 6 and a second driving component 7. The mounting base 6 is disposed at the driving end of the first driving component 5, and the fixed end of the second driving component 7 is connected to the mounting base 6. The driving end of the second driving component 7 is connected to the positioning and fixing component 1, and the second driving component 7 is used to drive the positioning and fixing component 1 to rotate in the horizontal direction. Under the driving action of the second driving component 7, the orientation of the positioning and fixing component 1 can be changed, thereby realizing the orientation change of the irregularly shaped battery located on the positioning and fixing component 1, thus adapting to different loading or unloading operation requirements.
[0051] In this embodiment, the first drive component 5 is a drive module, and the second drive component 7 is a drive motor.
