Description

Technical Field

[0001] This utility model relates to the field of battery assembly equipment technology, and in particular to an automatic feeding and positioning mechanism for cell pitch-changing modules. Background Technology

[0002] In the production and assembly process of new energy battery packs, multiple cells need to be arranged and assembled according to specific spacing requirements. The accuracy of the spacing between cells affects the heat dissipation performance and structural stability of the battery pack. Therefore, ensuring the positioning accuracy of cells during the assembly process is a crucial step in battery production.

[0003] However, in existing cell assembly technologies, the adjustment of the spacing between cells and subsequent loading and positioning operations rely on manual operation or simple fixed fixtures. Manual operation makes it difficult to ensure that the spacing between each cell is completely consistent. This inconsistency will lead to cumulative errors in subsequent welding and assembly steps. Furthermore, manual handling and positioning of cells is inefficient and can damage the cell surface. Although some automated equipment exists, most existing equipment cannot simultaneously achieve synchronous equidistant adjustment of multiple cells and integrated automatic loading and transfer. This functional fragmentation results in a cumbersome production process and low equipment integration.

[0004] Therefore, this utility model proposes an automatic feeding and positioning mechanism for battery cell pitch-changing modules to address the shortcomings of existing technologies. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] Example: Please refer to Figures 1 to 4 This utility model provides an automatic feeding and positioning mechanism for the cell pitch module, which aims to solve the problems of large errors and low efficiency in the manual spacing and feeding operations during the assembly of the cell block 4 in the prior art.

[0024] Please refer to Figure 1 The automatic feeding and positioning mechanism for the battery cell pitch-adjusting module includes a body 1, a pitch-adjusting mechanism 2 installed inside the body 1 for adjusting the spacing of the battery cell blocks 4, and a material-grabbing mechanism 3 installed on the rear side of the outer wall of the body 1 for automatically gripping and transferring the battery cell blocks 4. The body 1 serves as the basic support component of the whole and provides installation space for the pitch-adjusting mechanism 2 and the material-grabbing mechanism 3. The pitch-adjusting mechanism 2 realizes the automatic change of the spacing of the battery cell blocks 4 through mechanical transmission, and the material-grabbing mechanism 3 realizes the automated feeding operation of the battery cell blocks 4 through multi-axis linkage.

[0025] Please refer to Figure 2 and Figure 3 The adjusting mechanism 2 includes a motor 201 fixedly connected to the side wall of the body 1. The motor 201 serves as a power source to provide rotational driving force. A rotating shaft 202 is fixedly connected to the output end of the motor 201. The rotating shaft 202 rotates synchronously with the motor 201. A spiral or cam-shaped movable groove 203 is opened on the outer wall of the rotating shaft 202. A positioning member 210 is slidably connected to the inner wall of the movable groove 203. The positioning member 210 is restricted to moving only along the axial direction. A positioning disk 204 is fixedly connected to the top of the positioning member 210. Multiple sets of positioning disks 204 are arranged side by side along the length direction of the body 1. Slide rails 211 are fixedly connected to both the front and rear ends of the top of the body 1. A transmission rod 209 is fixedly connected to both the front and rear sides of the outer wall of the positioning disk 204. The end of the transmission rod 209 away from the positioning disk 204 is slidably engaged with the inner wall of the slide rail 211. The sliding of the transmission rod 209 in the slide rail 211 can assist the positioning disk 204 to move smoothly and prevent the positioning disk 204 from radially offset.

[0026] Please refer to Figure 2 and Figure 3The outer walls of adjacent positioning disks 204 are connected by a linkage assembly. The linkage assembly includes a second linkage 208 rotatably connected to the outer wall of the positioning disk 204 and a first linkage 206 rotatably connected to the outer wall of the adjacent positioning disk 204. The end of the first linkage 206 away from the positioning disk 204 and the end of the second linkage 208 away from the positioning disk 204 are rotatably connected by a joint button 207. The first linkage 206, the second linkage 208, and the joint button 207 together constitute a scissor-type telescopic mechanism. The joint button 207 allows the second linkage 208 and the first linkage 206 to rotate around the joint button 207 to change their angle, thereby realizing the extension and retraction of the linkage assembly as a whole. In the assembled state, the positioning disk 204, the first linkage 206, the second linkage 208, and the joint button 207 form a multi-stage linkage variable pitch structure. When the motor 201 drives the rotating shaft 202 to rotate, it drives the positioning component 210. During movement, the first positioning disk 204 moves under force. The first positioning disk 204 pulls the subsequent positioning disks 204 sequentially through the first connecting rod 206 and the second connecting rod 208, causing them to move in sequence. Since the first connecting rod 206 and the second connecting rod 208 are of equal length and symmetrically arranged, the spacing between all positioning disks 204 will remain consistent and change synchronously. The scissor-type multi-stage linkage structure ensures that the battery cell 4 can be placed at a large, easy-to-operate spacing, and can be quickly adjusted to a tight assembly spacing during assembly, effectively reducing the error caused by manual arrangement of the battery cell 4. Furthermore, the top of the positioning disk 204 is provided with placement slots 205 at equal intervals. The shape of the placement slots 205 is adapted to the shape of the battery cell 4. The placement slots 205 are used to stably accommodate and fix the battery cell 4 during the movement of the positioning disk 204, preventing the battery cell 4 from shaking or falling off.

[0027] As a preferred embodiment, in order to enable the battery cell 4 to be automatically picked up and transferred to the designated position after the pitch change is completed, please refer to... Figure 4 The material handling mechanism 3 includes a support frame 301 fixedly connected to the rear side of the body 1. A rotating groove 305 is provided at the top center of the support frame 301. A servo motor 302 is fixedly installed on the support frame 301. The servo motor 302 serves as a rotation drive source. An output shaft 303 is fixedly connected to the output end of the servo motor 302. A rotating arm 304 is fixedly connected to the middle of the outer wall of the output shaft 303. The rear end of the rotating arm 304 is fitted with the internal space of the rotating groove 305. Driven by the output shaft 303, the rotating arm 304 can perform large-scale reciprocating rotation within the space provided by the rotating groove 305, thereby covering the working range of the material handling mechanism 3 above the distance adjustment mechanism 2 and the predetermined assembly area.

[0028] As another preferred embodiment, in order to adapt to the grasping requirements at different heights and to achieve the adsorption of the battery cell 4, a telescopic arm 308 is rotatably installed on the front outer wall of the rotating arm 304. A tray 309 is fixedly connected to the extended end of the telescopic arm 308. The telescopic arm 308 is configured to drive the tray 309 to make linear reciprocating motion along the length direction of the telescopic arm 308, thereby moving the tray 309 to the top of the body 1. Suction grooves 307 are equally spaced on the bottom of the tray 309. The number of suction grooves 307 is the same as the number of positioning disks 204 and their positions correspond one-to-one. A micro air pump 310 is fixedly installed on the top of the inner wall of the suction groove 307. The micro air pump 310 is configured to generate negative pressure in the suction groove 307 to adsorb the battery cell 4.

[0029] As a further preferred embodiment, in order to facilitate the detachment and loading of the battery cell 4 after transfer, a second servo motor 306 is also fixedly installed on the front outer wall of the rotating arm 304. The output end of the second servo motor 306 is connected to the side wall of the telescopic arm 308. The second servo motor 306 is configured to drive the telescopic arm 308 to rotate around the output end of the second servo motor 306 as the axis, thereby causing the tray 309 and the battery cell 4 adsorbed on the tray 309 to rotate to a suitable detachment angle. With the help of the micro air pump 310 stopping work or blowing air in the opposite direction, the battery cell 4 is automatically unloaded.

[0030] Working principle: When assembling the battery cell 4, the motor 201 is first started. The rotation of the output end of the motor 201 causes the rotating shaft 202 fixed to the left side of the output end of the motor 201 to rotate synchronously. During the rotation of the rotating shaft 202, the movable groove 203 also rotates. The rotation of the movable groove 203 causes the positioning component 210 set on the inner wall of the movable groove 203 to move. When the positioning component 210 moves, it drives the positioning disk 204 fixed on the top of the positioning component 210 to move. As the positioning disk 204 on the left moves, the outer wall of the positioning disk 204 is rotatably connected to the connecting rod 208. The right side of the connecting rod 208 is rotatably connected to the connecting rod 206 via the joint button 207. The joint button 207 allows the connecting rod 208 and the connecting rod 206 to close and open, completing the positioning disks 204. The positioning disk 204 moves synchronously, driven by the positioning disk 204 with the positioning component 210 fixed at the bottom. During the movement of the positioning disk 204, the transmission rod 209 is fixedly connected to the left and right sides of the outer wall of the positioning disk 204. The transmission rod 209 moves along the inner wall of the slide rail 211 fixed at the front and rear ends of the top of the machine body 1, which assists the movement of the positioning disk 204 and prevents the movement path of the positioning disk 204 from being displaced. When the positioning disk 204 opens to the working position, the battery cell 4 is placed into the placement slot 205 that is equidistantly opened on the top of the positioning disk 204. Then the motor 201 is started to reverse, closing the positioning disk 204 so that the battery cell 4 is adjusted. Thus, the battery cell 4 is assembled at a fixed distance by adjusting the distance through the adjusting mechanism 2, reducing the error of manual assembly. After the adjusting mechanism 2 completes the positioning of the battery cell 4, a support frame 301 is set on the rear side of the outer wall of the body 1. The support frame 301 supports the servo motor 302 fixed at the bottom left and right ends of the support frame 301. An output shaft 303 is fixedly connected to the output end of the servo motor 302. Since a rotating arm 304 is fixedly connected to the middle of the outer wall of the output shaft 303, when the output end of the servo motor 302 rotates, it drives the output shaft 303 to rotate, thereby driving the rotating arm 304 to rotate. Because a rotating groove 305 is opened in the middle of the top of the support frame 301, the rotating arm 304 can rotate a large range. When the rotating arm 304 rotates to the working area, the telescopic arm 308 installed on the front side of the outer wall of the rotating arm 304 is extended. The tray 309 fixed to the extended end of the telescopic arm 308 is displaced by the telescopic arm 308. The cooperation between tray 309 and 08 allows tray 309 to move to the top of the body 1, so that the suction grooves 307 at equal intervals on the bottom of tray 309 fit together with the battery cell 4. At this time, the micro air pump 310 fixed to the top of the inner wall of suction groove 307 is activated. The micro air pump 310 applies negative pressure to suction the battery cell 4, so that the battery cell 4 is stably suctioned in suction groove 307. Then, the tray 309 is moved to the assembly area by servo motor 1 302 and telescopic arm 308. Finally, the output end of servo motor 2 306 fixed to the front of rotating arm 304 is rotated. The output end of servo motor 2 306 adjusts the angle of telescopic arm 308, flipping tray 309 so that the battery cell 4 can stably fall off the inner wall of suction groove 307. The feeding mechanism 3 enables the battery cell 4 to be stably fed, reducing errors caused by unnecessary manual operation and improving product quality.
