Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a current collector correction mechanism. Background Technology

[0002] In the welding of current collectors for cylindrical batteries, the current collectors need to be assembled to the cell at a specific angle to ensure welding accuracy and quality. For example... Figure 12 As shown, a current collector 7 of a certain model has a generally circular shape. A circular groove 71 is concentrically arranged in the central area, and five raised ribs 72 are evenly distributed around the circumference of the groove 71. A shaped circular hole 73 is located at the center of the area between two adjacent raised ribs 72. When welding the current collector 7 to the battery cell, the weld seam must be within the area of ​​the raised ribs 72. Typically, to ensure that the current collector 7 is fed at a specific angle, the angle of the current collector 7 needs to be corrected before feeding.

[0003] In practice, a robotic arm typically picks up the collector plate 7 and places it on a fixture. A servo motor drives the fixture to rotate, and a laser rangefinder detects the position of the raised rib 72 during rotation. Once the laser rangefinder detects the raised rib 72, the servo motor stops driving. However, the raised rib 72 is formed by stamping, and its edges have a beveled structure, which can easily lead to inaccurate detection by the laser rangefinder, affecting the subsequent welding accuracy.

[0032] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0033] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] 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 be limiting of the invention.

[0035] Please refer to Figures 1 to 11 A collector plate correction mechanism includes a guide rail plate 1, a fixed shuttle assembly 2, a lifting shuttle assembly 3, a correction assembly 4, and a vision assembly 5. The guide rail plate 1 extends along a first direction A. The fixed shuttle assembly 2 and the lifting shuttle assembly 3 are both movably disposed on a first side of the guide rail plate 1 along the first direction A. The fixed shuttle assembly 2 includes a first clamp 21 for assembling the collector plate 7, and the lifting shuttle assembly 3 includes a second clamp 31 for assembling the collector plate 7. In the vertical direction, the fixed shuttle assembly 2 is located above the lifting shuttle assembly 3, and the second clamp 31 can move in the vertical direction to be lower than or at the same height as the first clamp 21. The correction assembly 4 is disposed on the first side of the guide rail plate 1 and is used to drive the first clamp 21 and the second clamp 31 to adjust the collector plate 7. The vision assembly 5 is located above the guide rail plate 1, and in the first direction A, both the fixed shuttle assembly 2 and the lifting shuttle assembly 3 can reciprocate between the vision assembly 5 and the correction assembly 4.

[0036] Optionally, the vision component 5 includes a CCD camera 53.

[0037] In use, after the collector plate 7 is fed onto the first clamp 21 on the fixed shuttle assembly 2, the fixed shuttle assembly 2 moves below the vision assembly 5. The vision assembly 5 takes a picture and identifies the collector plate 7 on the fixed shuttle assembly 2, stores the information of the collector plate 7 on the fixed shuttle assembly 2, and compares this information with the preset information of the collector plate 7, specifically the angle information of the protruding rib 72 on the collector plate 7. Then, the fixed shuttle assembly 2 moves from the vision assembly 5 to the correction assembly 4, and the correction assembly 4 drives the first clamp 21 to adjust the collector plate 7 on the first clamp 21 to the preset posture; Accordingly, the difference between the lifting shuttle assembly 3 and the fixed shuttle assembly 2 is that after the lifting shuttle assembly 3 loads the collection tray 7, it moves to below the vision assembly 5. At this time, the second clamp 31 moves upward to the same height as the first clamp 21 so that the vision assembly 5 can detect the collection tray 7 and record its information. Then, the second clamp 31 resets, and the lifting shuttle assembly 3 moves to the correction assembly 4. The second clamp 31 moves upward to the same height as the first clamp 21, and finally, the correction assembly 4 drives the second clamp 31 to adjust the collection tray 7 on the second clamp 31 to a preset posture. In this way, the fixed shuttle assembly 2 and the lifting shuttle assembly 3 can be used together to improve the correction efficiency of the collection tray 7. At the same time, the vision assembly 5 can effectively avoid the influence of the sloping structure of the rib 72 by identifying the collection tray 7, which is beneficial to improving the correction accuracy.

[0038] For example, while the collector plate 7 on the fixed shuttle assembly 2 is correcting its alignment at the correction assembly 4, the collector plate 7 on the lifting shuttle assembly 3 is photographed and detected at the vision assembly 5. Once the collector plate 7 on the fixed shuttle assembly 2 has completed its alignment, it can be unloaded. The fixed shuttle assembly 2 moves to the vision assembly 5 to load the material and take a picture for detection, while the lifting shuttle assembly 3 moves to the correction assembly 4 to correct its alignment and unload the corrected collector plate 7. This cycle can be repeated.

[0039] Preferably, in the first direction A, the fixed shuttle assembly 2 and the lifting shuttle assembly 3 are linked. In this way, the fixed shuttle assembly 2 and the lifting shuttle assembly 3 can be driven by a single drive mechanism.

[0040] Furthermore, both the fixed shuttle assembly 2 and the lifting shuttle assembly 3 are slidably connected to the guide rail plate 1. A first synchronous belt 6 is mounted on the guide rail plate 1, and the fixed shuttle assembly 2 and the lifting shuttle assembly 3 are linked together via the first synchronous belt 6. Specifically, as shown... Figure 3 As shown, the guide rail plate 1 includes a plate body 11, an upper extension plate 13, and a lower extension plate 12. The upper extension plate 13 and the lower extension plate 12 are parallel and both extend along a first direction A. The upper extension plate 13 and the lower extension plate 12 are fixedly installed on the plate body 11. In the vertical direction, the upper extension plate 13 is higher than the lower extension plate 12. The fixed shuttle assembly 2 is slidably installed on the upper extension plate 13, and the lifting shuttle assembly 3 is slidably installed on the lower extension plate 12. Two first synchronous belt 6 wheels are rotatably installed on the plate body 11, and both synchronous wheels 61 are... Located between the upper extension plate 13 and the lower extension plate 12, the two synchronous pulleys 61 are of the same specification, and the line connecting their center points is parallel to the first direction A. The first synchronous belt 6 links the two synchronous pulleys 61, one of which is the driving pulley and the other is the driven pulley. The fixed shuttle assembly 2 is fixed on the upper side of the first synchronous belt 6, and the lifting shuttle assembly 3 is fixed on the lower side of the first synchronous belt 6. Therefore, when the first synchronous belt 6 moves, the fixed shuttle assembly 2 and the lifting shuttle assembly 3 can move closer or further away synchronously along the first direction A.

[0041] like Figure 4 As shown, the fixed shuttle assembly 2 also includes a first support plate 22, which is slidably connected to the guide rail plate 1 via an upper extension plate 13. Multiple first clamps 21 are provided, spaced apart along a first direction A on the first support plate 22; the first clamps 21 are rotatably connected to the first support plate 22. In this embodiment, the first support plate is slidably connected to the upper extension plate 13 via a slide rail slider assembly. Optionally, there are ten first clamps 21. Thus, the fixed shuttle assembly 2 can achieve correction of ten collector plates 7 in a single operation.

[0042] like Figure 1As shown, the lifting shuttle assembly 3 also includes a second support plate 32 and a third support plate 33. The second support plate 32 is slidably connected to the guide rail plate 1. A first adjusting plate 34 is disposed on the side of the second support plate 32 away from the guide rail plate 1. The third support plate 33 is slidably mounted on the first adjusting plate 34 in the vertical direction. There are multiple second clamps 31, which are spaced apart on the third support plate 33 along the first direction A. The second clamps 31 are rotatably connected to the third support plate 33. Specifically, the second support plate 32 is slidably connected to the lower extension plate 12 through a slide rail slider assembly, that is, the second support plate 32 is slidably connected to the guide rail plate 1 through the lower extension plate 12. In this embodiment, there are two first adjusting plates 34, which are spaced apart along the first direction A. The third support plate 33 spans between the two first adjusting plates 34. Preferably, the third support plate 33 is slidably connected to the first adjusting plate 34 through a slide rail slider assembly.

[0043] like Figure 7 As shown, the second support plate 32 is further provided with a drive frame 35, and the drive frame 35 is provided with a second drive member 36. The second drive member 36 acts on the third support plate 33 so that it can move vertically relative to the first adjusting plate 34. Optionally, the second drive member 36 is a cylinder.

[0044] In the lifting shuttle assembly 3, the structure composed of the second support plate 32, the first adjustment plate 34 and the third support plate 33 can move along the first direction A. The third support plate 33 can move in the vertical direction relative to the first adjustment plate 34. In this way, the attitude adjustment of the lifting shuttle assembly 3 can be realized, and it can be used in conjunction with the fixed shuttle assembly 2 without interference.

[0045] like Figures 4 to 6 As shown, the first clamp 21 includes a rotating shaft 211, a three-jaw cylinder 212, and a gripping finger block 213. The rotating shaft 211 passes through the first support plate 22 and is rotatably connected to it. The three-jaw cylinder 212 is located at the upper end of the rotating shaft 211 and is coaxial with the rotating shaft 211. An air guide channel 2111 is provided inside the rotating shaft 211. A rotary pneumatic connector 2112 is provided at the air inlet of the air guide channel 2111, and a conventional pneumatic connector 2113 is provided at the air outlet of the air guide channel 2111. 113, the rotary pneumatic connector 2112 is connected to a compressed air source (not shown in the figure), and the conventional pneumatic connector 2113 is connected to a three-jaw cylinder 212; there are three gripping finger blocks 213, which are assembled one-to-one on the three jaw bodies 2121 of the three-jaw cylinder 212. The gripping finger blocks 213 are provided with vertical limiting surfaces 2131 and horizontal limiting surfaces 2132. The collector plate 7 overlaps with the vertical limiting surface 2131 and is located within the space enclosed by the horizontal limiting surfaces 2132 of the three gripping finger blocks 213. Specifically, as shown... Figure 6As shown, the rotating shaft 211 is rotatably connected to the first support plate 22 via bearings. The air inlet of the air guide channel 2111 is located near the lower end of the rotating shaft 211, and the air outlet of the air guide channel 2111 is located near the upper end of the rotating shaft 211. The rotary pneumatic connector 2112 is connected to the compressed air source through the first air pipe (not shown in the figure), which can prevent the first air pipe from getting tangled during the rotation of the shaft. The conventional pneumatic connector 2113 is connected to the three-jaw cylinder 212 through the second air pipe (not shown in the figure). The driving gas comes from the compressed air source, is introduced into the air guide channel 2111 through the first air pipe and the rotary pneumatic connector 2112, and flows to the three-jaw cylinder 212 through the conventional pneumatic connector 2113 and the second air pipe, where it acts on the three-jaw cylinder 212. During use, the collector plate 7 is fed to the vertical limiting surface 2131. It is important to emphasize that the vertical limiting surfaces 2131 on the three gripping finger blocks 213 are all planes parallel to the horizontal plane, and the vertical limiting surfaces 2131 on the three gripping finger blocks 213 are at the same height. This ensures that after the collector plate 7 is fed and overlaps the three vertical limiting surfaces 2131, it is in a horizontal position. When the three-jaw cylinder 212 is activated, the three gripping finger blocks 213 tighten inwards, and under the action of the horizontal limiting surface 2132, the collector plate 7 is positioned coaxially with the three-jaw cylinder 212. Specifically, as shown... Figure 8 As shown, this allows the collector plate 7 to rotate synchronously with the three-jaw cylinder 212, so as to facilitate the adjustment and correction of the collector plate 7.

[0046] like Figure 4 and Figure 6 As shown, the rotating shaft 211 includes a shaft portion 211a and a shoulder portion 211b. The shoulder portion 211b is disposed on the shaft portion 211a and is located on the upper side of the first support plate 22. A wear-resistant washer 221 is disposed on the first support plate 22 and is coaxially sleeved on the outside of the shaft portion 211a. A positioning ball 2114 corresponding to the wear-resistant washer 221 is disposed on the shoulder portion 211b, and the positioning ball 2114 abuts against the wear-resistant washer 221. Preferably, the wear-resistant washer 221 is a steel washer. There are three positioning balls 2114, which are evenly distributed along the circumference of the rotating shaft 211. Under normal conditions, the positioning balls 2114, in conjunction with the wear-resistant washer 221, rely on the static friction between the two to keep the rotating shaft 211 and the first support plate 22 relatively stationary, thereby maintaining the stability of the collector plate 7 on the first clamp 21. When the collector plate 7 needs adjustment, the alignment component 4 drives the rotating shaft 211 to rotate. During this process, the positioning ball 2114 moves with the shaft shoulder 211b relative to the wear-resistant washer 221 to achieve attitude adjustment of the collector plate 7 on the first clamp 21. The positioning ball 2114, together with the wear-resistant washer 221, can achieve circumferential self-locking of the first clamp 21 without affecting its circumferential adjustment.

[0047] like Figure 9 and Figure 10As shown, the correction assembly 4 includes a first frame 41, an adapter plate 42, and a mounting plate 43. The adapter plate 42 is movably mounted on the first frame 41 along a first direction A, and the mounting plate 43 is slidably mounted on the adapter plate 42. The mounting plate 43 can move closer to or further away from the guide rail plate 1. A correction module 44 is disposed on the mounting plate 43, and the correction module 44 includes friction wheels 441 for driving the first clamp 21 and the second clamp 31. Specifically, the adapter plate 42 is movably mounted on the first frame 41 via a linear module. That is, the first frame 41 is equipped with a linear module, the adapter plate 42 is mounted on the linear module, and is driven by the linear module to move along the first direction A. The mounting plate 43 and the adapter plate 42 are slidably connected by a slide rail slider assembly. In this embodiment, a cylinder is disposed on the adapter plate 42, which is used to drive the mounting plate 43 to move relative to the adapter plate 42, so that the friction wheels 441 on the mounting plate 43 can move closer to or further away from the guide rail plate 1. More specifically, when a correction operation is required, the friction wheel 441 approaches the guide rail plate 1 to act on the first clamp 21 or the second clamp 31; after the correction operation is completed, the friction wheel 441 moves away from the guide rail plate 1 to avoid interference with the fixed shuttle assembly 2 and the lifting shuttle assembly 3.

[0048] Furthermore, such as Figure 10 As shown, the correction module 44 also includes a first limiting block 442, a second limiting block 443, a second adjusting plate 444, a first mounting bracket 446, and a second mounting bracket 447. The first limiting block 442 and the second limiting block 443 are both disposed on the mounting plate 43. The first limiting block 442 is disposed closer to the guide rail plate 1 than the second limiting block 443. The second adjusting plate 444 is slidably mounted on the mounting plate 43 via a slide rail slider assembly. A buffer spring 445 is disposed between the second limiting block 443 and the second adjusting plate 444. The buffer spring 445 acts on the second adjusting plate 444 so that the second adjusting plate 444 has a tendency to move toward the guide rail plate 1. The first limiting block 442 is used to limit the second adjusting plate 444.

[0049] Friction wheel 441 is rotatably mounted on first mounting bracket 446. Second mounting bracket 447 is equipped with a first driving member 4471 for driving the friction wheel 441 to rotate. The first driving member 4471 is driveably connected to the friction wheel 441. Optionally, the first driving member 4471 is a motor. The first driving member 4471 and the friction wheel 441 are driveably connected via a second synchronous belt 4472. In use, a buffer spring 445 acts on the second adjusting plate 444, allowing the friction wheel 441 to press against the first clamp 21 and the second clamp 31 to ensure friction, but without causing excessive pressure or damage between them.

[0050] In this embodiment, the first clamp 21 and the second clamp 31 have the same structure. In use, the friction wheel 441 acts on the shoulder 211b to drive the rotating shaft 211 to rotate.

[0051] In this embodiment, there are five correction modules 44, and ten first clamps 21 and ten second clamps 31. That is, one correction module 44 corresponds to two first clamps 21 and two second clamps 31. The adapter plate 42 moves relative to the first frame 41 in the first direction A to realize the switching position of the correction module 44 between the two clamps it corresponds to.

[0052] like Figure 11 As shown, the vision component 5 includes a second frame 51, a third adjustment plate 52, and a CCD camera 53. The third adjustment plate 52 is assembled to the second frame 51 via a linear module and can be driven by the linear module to move along the first direction A. The CCD camera 53 is correspondingly arranged with the first clamp 21 and the second clamp 31. There can be one, two, or more CCD cameras 53, as long as they can capture images of the collector plate 7 located below them.

[0053] This embodiment also provides a collector plate correction method, applied to the aforementioned collector plate correction mechanism, including the following steps:

[0054] Step S1: Establish a rectangular coordinate system with the center point of the outer circle contour of the collector plate 7 as the origin, and record the first angle data of the collector plate 7 under ideal conditions through the vision component 5;

[0055] Step S2: Record the second angle data of the collector disk 7 in the disordered state through the vision component 5;

[0056] Step S3: Drive the first clamp 21 and the second clamp 31 to rotate through the correction component 4 so that the second angle data coincides with the first angle data.

[0057] like Figure 13 The image shows the ideal orientation of the current collector 7. In this embodiment, the current collector 7 in its disordered state needs to be corrected to achieve the desired orientation. Figure 13 The state shown is illustrated. A reference line 74 is constructed by connecting the center point of the shaped circular hole 73 and the center point of the outer circular contour of the collector disk 7. In this embodiment, the ideal state of the collector disk 7 is described by taking the alignment of the reference line 74 with the Y-axis as an example, that is, the first angle data is that the angle between the reference line 74 and the Y-axis is 0°. Figure 14 As shown, in the Cartesian coordinate system XOY, since there are five shaped circular holes 73, there are theoretically five reference lines 74. The angle between any two adjacent reference lines 74 is 72°. Therefore, in a disordered state, the collector disk 7 must have at least one reference line 74 or shaped circular hole 73 located in the first quadrant. Thus, after photographing the disordered collector disk 7 using the vision component 5, the reference line 74 closest to the Y-axis in the first quadrant is selected, and the angle between this reference line 74 and the Y-axis is obtained, which is the aforementioned second angle data. Figure 14As shown, after rotating the collector plate 7 counterclockwise until the reference line 74 coincides with the Y-axis, the second angle data coincides with the first angle data, thus achieving the correction operation. It should be noted that after taking a picture, the vision component 5 outputs relevant data information to the correction component 4, which then drives the corresponding first clamp 21 and second clamp 31 to rotate by a specific angle. It should also be noted that in some embodiments, the design holes 73 are not limited to those in the first quadrant. For example, when there are three design holes 73, the design holes 73 in the disordered state of the collector plate 7 may not necessarily fall into the first quadrant. In principle, any design hole 73 can be selected. However, the closer the design hole 73 is to the Y-axis, the smaller the second angle data obtained, and the smaller the adjustment angle of the corresponding collector plate 7, which is beneficial to improving efficiency. This collector plate 7 correction method can achieve efficient and high-precision correction of the collector plate 7.
