[0002] With the rapid development of the new energy industry, cylindrical batteries, with their high energy density, excellent cycle performance, and strong structural stability, are seeing increasing demand in applications such as electric vehicles, energy storage devices, and portable electronic devices. As a core component of cylindrical batteries, the battery casing not only seals the electrolyte and protects the internal cells, but the quality of its welding also directly impacts the battery's safety, service life, and electrochemical performance.

[0017] By setting up the system, while the previous battery shell is being rotationally welded, the next battery shell has been grabbed by the electric gripper and is on standby at the welding position. That is, after the welding of the current shell is completed, the second turntable immediately rotates to send it to the next link, and the new battery shell enters the welding position at the same time. This "seamless connection" design method realizes the rapid welding of battery shells, is convenient for corresponding batch welding processing operations, has high process stability, solves the technical problem of low welding efficiency in traditional welding, and is easy to process and use.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] The specific implementation of the present invention is described in detail below with reference to specific embodiments. Example 1

[0032] See also Figures 1 to 10 An automated welding device for processing cylindrical battery casings includes a workbench 1, a connecting seat 3 is mounted on the workbench 1 via a support frame 2, a plurality of battery casings 36 to be processed are arranged on the workbench 1, a welding robot 48 for welding is arranged on one side of the workbench 1, and further includes: The feeding mechanism is installed on the workbench 1 and is used to arrange and transport the battery shells 36 one by one. The feeding mechanism includes a surrounding plate 23 and a limiting plate 49 for conveying. A first turntable 24 for rotating conveying is provided below the limiting plate 49. A conveyor belt 35 for linear conveying is provided below the surrounding plate 23. The conveyor belt 35 is driven for synchronous conveying by the rotation of the first turntable 24.

[0033] Furthermore, the feeding mechanism also includes a driving motor 28 for driving the first turntable 24 to rotate. The first turntable 24 is rotatably mounted on the workbench 1 through a first connecting shaft 25. A worm gear 26 is fixedly connected to the first connecting shaft 25. A worm 27 is meshedly connected to the worm gear 26. The worm 27 is fixedly connected to the output shaft of the driving motor 28. The driving motor 28 is fixedly mounted inside the workbench 1.

[0034] Furthermore, the feeding mechanism also includes a second connecting shaft 30 for driving the conveyor belt 35 for conveying. The worm 27 is rotatably connected to the second connecting shaft 30 through the bevel gear pair 29. The second connecting shaft 30 is rotatably installed inside the workbench 1 through the fixed block 31. The second connecting shaft 30 is rotatably connected to the active roller 33 through the synchronous belt 32. The conveyor belt 35 is transmission-connected to the active roller 33 and the driven roller 34. The driven roller 34 is rotatably installed on the workbench 1.

[0035] Preferably, when the battery housing 36 is welded, multiple battery housings 36 can be stacked in a disordered manner on the first turntable 24. At this time, the output shaft of the drive motor 28 drives the worm 27 to rotate, and the worm 27 and the worm wheel 26 are engaged and connected to drive the first turntable 24 on the first connecting shaft 25 to rotate. The specific direction of rotation can be seen in FIG. Figure 10 As shown, while the worm 27 rotates, it drives the second connecting shaft 30 to rotate under the connection relationship of the bevel gear pair 29, and the second connecting shaft 30 drives the active roller 33 to rotate under the synchronous driving action of the synchronous belt 32. At this time, the conveyor belt 35 is driven and transported under the transmission connection relationship between the active roller 33 and the driven roller 34, and under the limiting action of the limiting plate 49 and the enclosure 23, a plurality of disorderly arranged battery shells 36 are arranged in order on the conveyor belt 35 for transportation, thereby facilitating subsequent welding processing.

[0036] The first turntable 24 can accommodate a large number of disorderly stacked battery shells 36. There is no need for manual sorting and arrangement in advance. The initial dispersion and transportation of materials can be achieved only through the rotation of the first turntable 24, which greatly reduces the time cost of "manual plate arrangement". At the same time, the sequential arrangement of the conveyor belt 35 directly provides a good material state for subsequent processes, avoiding process interruptions caused by disordered shells, making the material flow rhythm of the entire production line more coherent, and indirectly improving the production capacity per unit time. Example 2

[0037] like Figures 1 to 6 As shown, this embodiment, based on embodiment 1, further includes a sequential loading mechanism, which is installed on the connecting seat 3, and is used to separate the conveyed battery shells 36 one by one and supply them in sequence. The sequential loading mechanism includes a first limiting fork rod 4 and a second limiting fork rod 5 for sequential loading. The first limiting fork rod 4 and the second limiting fork rod 5 are controlled by the movement of the second connecting plate 15 for sequential loading.

[0038] Furthermore, the sequential feeding mechanism also includes a pulley seat 8 and a guide pulley 9 for driving the first limiting fork rod 4 and the second limiting fork rod 5 to perform a limiting material connection. The first limiting fork rod 4 and the second limiting fork rod 5 are both slidably connected to the first connecting plate 6 through the first guide rod 7, and the first guide rod 7 is fixedly connected to the pulley seat 8. The guide pulley 9 is rotatably connected to the pulley seat 8. The pulley seat 8 is slidably connected to the first connecting plate 6 through the second guide rod 10. A return spring 11 is provided at the connection between the pulley seat 8 and the first connecting plate 6. The first connecting plate 6 is fixedly connected to the third connecting plate 18 through a fixing column 19. The first connecting plate 6 and the third connecting plate 18 are both fixedly installed inside the connecting seat 3.

[0039] Furthermore, the sequential feeding mechanism also includes a first drive plate 12 and a second drive plate 13 for driving the guide pulley 9 to be raised and lowered. The first drive plate 12 and the second drive plate 13 are both fixedly connected to the second connecting plate 15. The first drive plate 12 and the second drive plate 13 are both provided with a drive groove 14 that is adapted to be slidably connected to the guide pulley 9. The structures of the first drive plate 12 and the second drive plate 13 are mirror images, and the first drive plate 12 and the second drive plate 13 are arranged in parallel.

[0040] Furthermore, the sequential feeding mechanism also includes a first telescopic cylinder 21 for driving the second connecting plate 15 to perform movement control, the second connecting plate 15 is fixedly connected to a traction block 20, the traction block 20 is fixedly connected to the piston rod of the first telescopic cylinder 21, the first telescopic cylinder 21 is fixedly installed on the third connecting plate 18, the third connecting plate 18 is provided with a guide groove 22 for avoiding the traction block 20, and the second connecting plate 15 is fixedly connected to a slider 16, the slider 16 is limitedly slidably connected to the slide rail 17, and the slide rail 17 is fixedly installed on the third connecting plate 18.

[0041] Preferably, in this embodiment, when the battery shells 36 are transported one by one on the conveyor belt 35 in order, in order to ensure the smooth progress of the subsequent welding process, it can be seen that Figure 4 and Figure 5As shown, the first limiting fork rod 4 limits the front of the battery housing 36, and the second limiting fork rod 5 limits the rear of the battery housing 36. When the battery housings 36 need to be separated one by one and supplied to the welding operating table behind in sequence, the first telescopic cylinder 21 drives the second connecting plate 15 connected to the traction block 20 for movement control. Under the guidance of the slider 16 and the slide rail 17, the first driving plate 12 and the second driving plate 13 on the second connecting plate 15 are driven to move. Control, because the guide pulley 9 on the pulley seat 8 is adapted to be slidably connected in the driving groove 14, and is lifted and lowered under the elastic reset action of the return spring 11, the lifting and lowering control of the first limiting fork rod 4 and the second limiting fork rod 5 are completed according to the direction control of the first driving plate 12 and the second driving plate 13. At this time, the battery housings 36 can be separated one by one and supplied to the second turntable 37 behind in sequence for corresponding welding operations.

[0042] The first limiting fork rod 4 and the second limiting fork rod 5 can effectively avoid the problems of "shell stacking" and "too close spacing" that may occur when the conveyor belt 35 is continuously conveying through the coordinated action of "alternating blocking-releasing". This "separation one by one" method can significantly improve the accuracy of the supply of battery shells 36, thereby facilitating subsequent welding operations. In addition, the limiting effect of the fork rod can further calibrate the posture of the battery shell 36 during the separation process (such as correcting a slight offset of the shell through the arc-shaped contact surface of the fork rod), so that the battery shell 36 can enter the welding operating table more accurately, which is convenient for subsequent grabbing and releasing. The welding process is well protected. In addition, the automatic separation and supply mechanism of the first limit fork rod 4 and the second limit fork rod 5 can realize the whole process of "from the conveyor belt to the welding operation table" without human intervention, which greatly reduces the amount of manual operation. At the same time, the running status of the fork rod can be monitored in real time by the sensor (such as detecting whether the fork rod is normally extended and retracted, which is not shown in detail in the article). If there is an abnormality such as jamming or misalignment, the system will immediately shut down and alarm to avoid "shell jamming causing equipment damage" or "disorderly supply causing welding accidents" due to mechanical failure, further improving the safety and stability of the production process. Example 3

[0043] like Figures 1 to 10 As shown, this embodiment, based on the above embodiment, further includes a welding and unloading mechanism, which is installed on the workbench 1 and is used for loading, welding and unloading the battery shells 36 that are transported one by one. The welding and unloading mechanism includes a second turntable 37 for rotation processing and an electric clamp 44 for grabbing loading and unloading. The second turntable 37 is provided with a number of positioning grooves 38 for positioning the battery shells 36.

[0044] Furthermore, the welding blanking mechanism also includes a first turntable 40 for driving the second turntable 37 to rotate. The second turntable 37 is installed on the first turntable 40 through a third connecting shaft 39. The first turntable 40 is fixedly installed inside the workbench 1, and the welding robot 48 is arranged near the second turntable 37.

[0045] Furthermore, the welding blanking mechanism also includes a second rotating table 41 and a second telescopic cylinder 42 for driving the electric clamp 44 to rotate, lift and adjust. The electric clamp 44 is fixedly mounted on the top plate 43, and the top plate 43 is fixedly connected to the piston rod of the second telescopic cylinder 42. The second telescopic cylinder 42 is fixedly mounted on the second rotating table 41, and the second rotating table 41 is fixedly mounted on the workbench 1.

[0046] Furthermore, the welding unloading mechanism further includes a conveying platform 45 for unloading materials. The conveying platform 45 is fixedly mounted on the workbench 1 . A first conveyor 46 and a second conveyor 47 for feeding materials are provided on the conveying platform 45 .

[0047] Preferably, in this embodiment, whenever the battery shells 36 are transported one by one to the side of the second turntable 37 in sequence, the second telescopic cylinder 42 drives the electric clamp 44 to move down and grab, and then the second turntable 41 is controlled to rotate, so as to facilitate the placement of the transported battery shells 36 in the positioning grooves 38 on the second turntable 37 for positioning. The positioning methods of the positioning grooves 38 for the battery shells 36 include but are not limited to suction cup positioning or clamp positioning, so that when the first turntable 40 controls the second turntable 37 to rotate to a certain angle, the welding robot 48 on the side can perform welding processing accordingly.

[0048] When the battery shell 36 after the welder is transported to the side close to the first conveyor 46, the second rotating table 41 drives the electric clamp 44 on the second telescopic cylinder 42 to move down and grab it, so as to facilitate the placement of the welded battery shell 36 on the first conveyor 46 for transportation. Then the first conveyor 46 is transported by the second conveyor 47 to facilitate the transportation of the welded battery shell 36.

[0049] While the previous battery shell 36 is being rotationally welded, the next battery shell 36 has been grabbed by the electric clamp 44 and is on standby at the welding position. That is, after the current shell is welded, the second turntable 37 immediately rotates to send it to the next link, and at the same time, the new battery shell 36 enters the welding position. This "seamless connection" design method realizes the rapid welding of the battery shell 36, is convenient for corresponding batch welding processing operations, has high process stability, solves the technical problem of low welding efficiency in traditional welding, and is convenient for processing and use.

[0050] It should be noted that how the electric gripper 44 controls the gripping is common knowledge to those skilled in the art and will not be elaborated in detail herein.

[0051] It should be noted that the components in this application are all universal standard parts or components well known to those skilled in the art, which effectively solve the technical problems raised in the background technology.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
