Description

Technical Field

[0001] This utility model relates to the field of battery technology, specifically to a current collector feeding mechanism and a current collector welding device. Background Technology

[0002] In the production process of lithium batteries, it is necessary to weld the current collectors and wrap the circumference of the battery electrodes. The former is to connect the electrodes of the entire cell to form a whole, while the latter is to ensure the insulation of the electrodes inside the battery and prevent them from contacting the steel shell. Both of these processes are indispensable parts of lithium battery production.

[0003] Currently, before welding, the current collector needs to be placed in a designated position, and then the current collector to be processed is attracted by the welding adsorption plate. Then, the current collector is welded to the battery cell by laser. However, the current current collector feeding is relatively slow. Sometimes, due to the layout of the site, the location of the current collector storage component is too far from the location of the current collector welding component, resulting in slow feeding. Some even need to be placed manually one by one, resulting in low production efficiency. Utility Model Content

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0023] Please see Figure 1 One embodiment of this utility model provides a collector tray feeding mechanism, including: a collector tray handling component 10, a collector tray storage component 20, a collector tray transfer seat 30, and a collector tray positioning seat 40.

[0024] The collector plate transfer seat 30 is arranged between the collector plate storage component 20 and the collector plate positioning seat 40. The collector plate transport component 10 is used to transport the collector plates on the collector plate storage component 20 to the collector plate transfer seat 30 and the collector plate positioning seat 40 in sequence.

[0025] The current collector transport assembly 10 includes a two-axis transport module 11, a movable seat 12, several adsorption heads 13, and several welding adsorption plates 14. The two-axis transport module 11 is driven to the movable seat 12. The adsorption heads 13 and welding adsorption plates 14 are all mounted on the movable seat 12. The movable seat 12 can move to a first transport position and a second transport position in the direction from the current collector storage assembly 20 to the current collector positioning seat 40 under the drive of the two-axis transport module 11, and can also be raised and lowered under the drive of the two-axis transport module 11. The adsorption heads 13 and several welding adsorption plates 14 are all connected to a negative pressure generating device. After the negative pressure generating device is activated, a negative pressure is formed at the adsorption heads 13 and several welding adsorption plates 14 to adsorb the current collector to be processed. The welding assembly welds the current collector to be processed on the current collector positioning seat 40 to the electrodes of the battery cell to be processed.

[0026] When the movable seat 12 is in the first transport position, the adsorption head 13 is located at the collection plate storage component 20, and the welding adsorption plate 14 is located at the collection plate transfer seat 30.

[0027] When the movable seat 12 is in the second transport position, the adsorption head 13 is located at the transfer seat 30 of the collector plate, and the welding adsorption plate 14 is located at the positioning seat 40 of the collector plate.

[0028] The working principle of the feeder mechanism of the collector plate according to one embodiment of this utility model is described below: The two-axis transport module 11 drives the movable seat 12 to move to the first transport position, and then drives the movable seat 12 to descend, so that the adsorption head 13 adsorbs the collector plate to be processed on the collector plate storage assembly 20, and the welding adsorption plate 14 adsorbs the collector plate to be processed on the collector plate transfer seat 30.

[0029] Subsequently, the two-axis transport module 11 drives the movable seat 12 to rise, then drives the movable seat 12 to move to the second transport position, and then drives the movable seat 12 to fall. Then, the suction head 13 releases its suction from the collector plate to be processed, so that the collector plate to be processed on the suction head 13 is placed on the collector plate transfer seat 30, and the welding suction plate 14 releases its suction from the collector plate to be processed, so that the collector plate to be processed on the welding suction plate 14 is placed on the collector plate positioning seat 40. This cycle is repeated, so that the collector plates to be processed on the collector plate storage component 20 can be continuously transported to the collector plate positioning seat 40.

[0030] The design of the transfer seat 30 in the collector tray reduces the distance that the movable seat 12 moves each time, effectively speeding up the production cycle.

[0031] The specific structure of the two-axis conveying module 11 can be designed according to actual needs. For example, in one embodiment, the two-axis conveying module 11 includes a lateral translation module and a vertical translation module. The lateral translation module is driven to connect with the vertical translation module, and the vertical translation module is driven to connect with the movable seat 12. The lateral translation module drives the vertical translation module and the movable seat 12 to move back and forth together in the direction from the collector storage assembly 20 to the collector positioning seat 40. The lateral translation module drives the movable seat 12 to rise and fall. The lateral translation module and the vertical translation module can be a lead screw drive assembly, a rotary motor translation drive assembly, a belt translation drive assembly, a cylinder translation drive assembly, or a linear motor translation drive assembly, etc.

[0032] In some optional embodiments, the collector plate transport assembly 10 includes multiple adsorption heads 13 and multiple welding adsorption plates 14. The multiple adsorption heads 13 are arranged side by side. The collector plate transport assembly 10 can simultaneously adsorb multiple collector plates to be processed through the multiple adsorption heads 13 and the multiple welding adsorption plates 14. The movable seat 12 can transport multiple collector plates to be processed at the same time with a single movement, which improves the transport efficiency.

[0033] Please see Figure 2 In some optional embodiments, the collector plate transfer base 30 is provided with a plurality of transfer positioning grooves 31 for positioning and cooperating with the collector plate to be processed. The collector plate to be processed is positioned by the transfer positioning grooves 31. It should be noted that the transfer positioning grooves 31 need to be adapted to the structure of the adsorption head 13 and the welding adsorption plate 14, so that the adsorption head 13 can place the collector plate to be processed in the transfer positioning groove 31 and the welding adsorption plate 14 can adsorb the collector plate to be processed in the transfer positioning groove 31. When the collector plate transport assembly 10 includes multiple adsorption heads 13 and multiple welding adsorption plates 14, multiple transfer positioning grooves 31 are arranged side by side on the collector plate transfer base 30.

[0034] Please see Figure 3 and Figure 4In some optional embodiments, the collector tray transport assembly 10 includes a support 21 and a collector tray lifting module 22. The support 21 is provided with a plurality of collector tray storage channels 211. The top and bottom of the collector tray storage channels 211 are respectively formed with a top port and a bottom port. The collector tray lifting module 22 is located below the collector tray storage channels 211. A part of the collector tray lifting module 22 extends into the collector tray storage channel 211 from the bottom port. When the movable seat 12 is in the first transport position, the suction head 13 is located at the top port of the collector tray storage channel 211. Multiple collector disks to be processed can be stored in the collector disk storage channel 211. The multiple collector disks to be processed in the collector disk storage channel 211 are stacked sequentially from top to bottom. The suction head 13 can be stopped above the top port, or stopped at the top port, or extended into the collector disk storage channel 211 from the top port. Then, the collector disk lifting module 22 drives the collector disks to be processed in the collector disk storage channel 211 to rise, so that the collector disk to be processed at the highest point in the collector disk storage channel 211 can contact the suction head 13.

[0035] It should be noted that since the welding of the manifolds is all done by laser, the structure of the welding adsorption plate 14 needs to be designed to avoid the laser. However, due to structural limitations, the welding adsorption plate 14 cannot adsorb the manifolds on the manifold storage component 20. Usually, an adsorption head 13 corresponding to the manifold storage component 20 is needed to adsorb the manifolds on the manifold storage component 20. Through the design of the manifold transfer seat 30, after the adsorption head 13 adsorbs and moves the manifolds on the manifold storage component 20 to the manifold transfer seat 30, the welding adsorption plate 14 can adsorb the manifolds from the manifold transfer seat 30. Therefore, it effectively avoids the situation where the welding adsorption plate 14 cannot adsorb the manifolds due to structural incompatibility between the welding adsorption plate 14 and the manifold storage component 20. Especially when the adsorption head 13 needs to extend into the manifold storage channel 211 to pick up the manifolds to be processed, the welding adsorption plate 14 cannot extend into the manifold storage channel 211 due to structural limitations.

[0036] In some optional embodiments, the collector tray transport assembly 10 further includes an adsorption lifting module 15, which is driven to connect with the adsorption head 13. The adsorption head 13 can be raised and lowered under the drive of the adsorption lifting module 15. When the movable seat 12 is in the first transport position, after the movable seat 12 is lowered, the welding adsorption plate 14 adsorbs the collector tray to be processed on the collector tray transfer seat 30. At this time, the adsorption lifting module 15 needs to drive the adsorption head 13 to a suitable position so that the adsorption head 13 can contact the collector tray to be processed in the collector tray storage channel 211. After the adsorption head 13 adsorbs the collector tray to be processed, the adsorption lifting module 15 drives the adsorption head 13 to rise to a suitable position so that the collector tray to be processed can be placed on the collector tray transfer seat 30 in the future.

[0037] The specific structure of the adsorption lifting module 15 can be designed according to actual needs. For example, the adsorption lifting module 15 can be a screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module.

[0038] The specific structure of the collector plate lifting module 22 can be designed according to actual needs. For example, in some optional embodiments, the collector plate lifting module 22 includes several push rods 221 and a push rod 221 driving module. The push rods 221 are located below the collector plate storage channel 211. The push rod 221 driving module is driven to the push rods 221. The push rods 221 can extend into the bottom port under the drive of the push rod 221 driving module. The push rods 221 can stably push the collector plate to be processed in the collector plate storage channel 211 to rise.

[0039] The specific structure of the push rod 221 drive module can be designed according to actual needs. For example, the push rod 221 drive module can be a lead screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module.

[0040] In some alternative embodiments, the support 21 has multiple collector tray storage channels 211 arranged side by side to accommodate more collector trays to be processed. When the collector tray handling assembly 10 includes multiple adsorption heads 13 and multiple welding adsorption trays 14, the adsorption heads 13 can adsorb the collector trays to be processed in the collector tray storage channels 211.

[0041] In some optional embodiments, the support 21 is provided with a first storage seat 212, a second storage seat 213 and a moving drive module 214. The first storage seat 212 and the second storage seat 213 are movably disposed on the support 21. Both the first storage seat 212 and the second storage seat 213 are provided with a collection tray storage channel 211. The moving drive module 214 is drivenly connected to the first storage seat 212 and the second storage seat 213. Under the drive of the moving drive module 214, when the movable seat 12 is in the first transport position, the first storage seat 212 or the second storage seat 213 is correspondingly located below the suction head 13. In this embodiment, both the first storage base 212 and the second storage base 213 are provided with the same number of collector tray storage channels 211 as the suction head 13. When the movable base 12 is in the first transport position, the first storage base 212 is initially positioned below the suction head 13. The suction head 13 picks up the collector trays to be processed from the collector tray storage channels 211 on the first storage base 212. After all the collector trays to be processed from the collector tray storage channels 211 on the first storage base 212 have been transported away, the motion drive module 214 moves the first storage base 212 away and moves the second storage base... 213 moves to the position corresponding to the position below the suction head 13, and then the suction head 13 picks up the unprocessed collection tray in the collection tray storage channel 211 on the second storage seat 213. At this time, the collection tray storage channel 211 of the first storage seat 212 can be filled with the unprocessed collection tray, so that after all the unprocessed collection trays in the collection tray storage channel 211 on the second storage seat 213 are removed, the first storage seat 212 is moved back to the position corresponding to the position below the suction head 13. In this way, there is no need to stop the production operation to fill the processing collection tray, ensuring continuous production.

[0042] The specific structure of the moving drive module 214 can be designed according to actual needs. For example, the moving drive module 214 can be a lead screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc. In this case, the moving drive module 214 drives the first storage seat 212 and the second storage seat 213 to translate. Of course, the moving drive module 214 can also achieve position switching by driving the first storage seat 212 and the second storage seat 213 to rotate. For example, in this embodiment, the moving drive module 214 is a geared motor, which is driven and connected to the first storage seat 212 and the second storage seat 213 to drive the first storage seat 212 and the second storage seat 213 to rotate around the geared motor; in addition, the geared motor can be driven and connected to a turntable, and the first storage seat 212 and the second storage seat 213 are arranged on the turntable.

[0043] Please see Figure 5In some optional embodiments, the top of the collector plate positioning seat 40 is provided with a plurality of positioning through slots 41. The positioning through slots 41 are used to position and cooperate with the collector plate to be processed, so that the welding adsorption plate 14 places the collector plate to be processed in the positioning through slots 41, thereby making the collector plate to be processed stably positioned to facilitate the subsequent welding process.

[0044] The aforementioned manifold feeding mechanism can be applied to a manifold welding device, which includes the aforementioned manifold feeding mechanism.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
