Description

A high-temperature impregnation and formation integration device for lithium batteries with pin removal function

[0001] This application claims a Chinese utility model patent with application number "2024226660399", application date "November 1, 2024", and title "A high-temperature wetting and formation integrated device for lithium batteries with pin removal function". Technical Field

[0002] This application relates to the technical field of lithium battery production, and in particular to a high-temperature wetting and formation integration device for lithium batteries with pin removal function. Background Technology

[0003] High-temperature immersion and formation processes are indispensable parts of the lithium battery production process. Traditional layout methods often follow the process flow, where a tray carrying the battery cells enters the high-temperature immersion chamber, undergoes high-temperature immersion within a specified process time, is then removed by a stacker crane, and sent to the formation workshop via a conveyor line to complete the formation process. Before formation, the liquid injection pins on the surface of the battery cells need to be removed.

[0004] In some production lines with low output efficiency, the efficiency of a single stacker crane in and out of the warehouse is far greater than the efficiency required by the production line. In the traditional layout, the high-temperature wetting warehouse and the chemical formation equipment are two separate workshops. Therefore, stacker cranes need to be configured separately for high-temperature wetting and chemical formation, resulting in wasted space and increased equipment investment.

[0005] Utility Model Content

[0006] In view of the above-mentioned problems in existing production operations, the aim is to provide a high-temperature wetting and formation integrated device for lithium batteries with pin removal function that is simple in structure, highly efficient and low in cost.

[0007] The specific technical solution is as follows:

[0008] A high-temperature impregnation and formation integrated device for lithium batteries with nail removal function includes a feeding conveyor line, a discharging conveyor line, a formation device disposed on the feeding conveyor line and the discharging conveyor line, a high-temperature impregnation chamber disposed on the side of the formation device, and a stacking machine disposed between the high-temperature impregnation chamber and the formation device. The device includes a nail removal machine installed on the feeding conveyor line for removing the glue-filled nails on the surface of the lithium battery cells after high-temperature impregnation.

[0009] In some embodiments, a first blocking limit mechanism, a second blocking limit mechanism, and a third blocking limit mechanism are sequentially arranged along the conveying direction on the feeding conveyor line to block and limit the material tray carrying the battery cells on the feeding conveyor line, and the nail puller is located between the first blocking limit mechanism and the second blocking limit mechanism.

[0010] In some embodiments, the feeding conveyor line is further provided with a first lifting and transferring mechanism and a second lifting and transferring mechanism, wherein the first lifting and transferring mechanism is located on the side of the first blocking and limiting mechanism away from the nail puller, and the second lifting and transferring mechanism is located between the second blocking and limiting mechanism and the third blocking and limiting mechanism.

[0011] In some embodiments, a circulating conveyor line is provided on the side of the feeding conveyor line, and the circulating conveyor line is provided with a third lifting and transferring mechanism and a fourth lifting and transferring mechanism. The third lifting and transferring mechanism and the second lifting and transferring mechanism are distributed in the front-back direction, and the fourth lifting and transferring mechanism and the first lifting and transferring mechanism are distributed in the front-back direction.

[0012] In some embodiments, the feeding end of the unloading conveyor line is provided with a fifth lifting and transferring mechanism.

[0013] In some embodiments, the feeding conveyor line, the unloading conveyor line, and the circulating conveyor line are all roller conveyor lines.

[0014] In some embodiments, the first blocking and limiting mechanism, the second blocking and limiting mechanism, and the third blocking and limiting mechanism are all pneumatic blocking and limiting mechanisms.

[0015] In some embodiments, the highest position of the first lifting and transferring mechanism and the second lifting and transferring mechanism is higher than the horizontal height of the conveying surface of the feeding conveyor line, and the lowest position is the same as the horizontal height of the conveying surface of the feeding conveyor line.

[0016] In some embodiments, the highest position of the third lifting and transferring mechanism and the fourth lifting and transferring mechanism is higher than the horizontal height of the conveying surface of the circulating conveyor line, and the lowest position is the same as the horizontal height of the conveying surface of the circulating conveyor line.

[0017] In some embodiments, the highest position of the fifth lifting and transferring mechanism is higher than the horizontal height of the conveying surface of the unloading conveyor line, and the lowest position is the same as the horizontal height of the conveying surface of the unloading conveyor line.

[0018] The positive effects of the above technical solution compared with the existing technology are:

[0019] (1) This application integrates the high-temperature immersion chamber and the formation cabinet on both sides of the stacker crane aisle when the overall line efficiency requirement is not high. After the high-temperature immersion is completed, the nail is removed by the nail removal machine set on the feeding conveyor line and then enters the formation cabinet, which is more in line with the actual production application scenario.

[0020] (2) The high-temperature immersion chamber and the formation cabinet are integrated in this application without increasing the ground space, which can use fewer stacker cranes and improve the working efficiency of the stacker cranes.

[0021] (3) The design of the circulating conveyor line for manual nail removal in this application is conducive to improving the efficiency of the entire line, reducing equipment waiting time due to nail removal failure, and improving processing efficiency. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0026] Figure 1 is a structural schematic diagram of a high-temperature wetting and formation integration device for lithium batteries with pin-removing function according to this application. As shown in Figure 1, an embodiment of a high-temperature wetting and formation integration device for lithium batteries with pin-removing function is illustrated. It includes a feeding conveyor line 1, a discharging conveyor line 5, a formation device 3 disposed on the feeding conveyor line 1 and the discharging conveyor line 5, a high-temperature wetting chamber 2 disposed on the side of the formation device 3, and a stacking machine 4 disposed between the high-temperature wetting chamber 2 and the formation device 3. The device includes a pin-removing machine 6 installed on the feeding conveyor line 1 for removing lithium batteries after high-temperature wetting. The glue-filled nails on the surface of the battery cells, and the pallet carrying the battery cells move forward through the feeding conveyor line 1. The stacker 4 forks the pallet and sends it into the corresponding storage location in the high-temperature wetting chamber 2 for storage. When the predetermined outbound time is reached, the stacker 4 forks the pallet in the high-temperature wetting chamber 2 and puts it into the feeding conveyor line 1 to continue to be conveyed forward. It passes through the nail removal machine 6 and removes the glue-filled nails on the outer surface of the battery cells on the pallet. The pallet carrying the battery cells continues to be conveyed forward through the feeding conveyor line 1 and is output to the nail removal machine 6. The stacker 4 forks the pallet again and puts it into the corresponding storage location in the formation cabinet for formation.

[0027] In this application, the high-temperature wetting chamber 2 and the formation cabinet are integrated on both sides of the stacker crane aisle when the overall line efficiency requirement is not high. After the high-temperature wetting is completed, the nail is removed by the nail remover 6 set on the feeding conveyor line 1 and then enters the formation cabinet, which is more in line with the actual production application scenario.

[0028] In this application, the high-temperature immersion chamber 2 and the formation cabinet are integrated and set up so that fewer stacker cranes can be used without increasing the floor space, which is conducive to improving the working efficiency of the stacker cranes.

[0029] Specifically, the nail puller 6, the feeding conveyor line 1, the unloading conveyor line 5, the chemical formation equipment 3, the high-temperature wetting chamber 2, and the stacker 4 are all existing mature equipment. The nail pulling control method of the nail puller 6 can be referred to Chinese invention patent CN116666767A, and the feeding conveyor line 1, the unloading conveyor line 5, the chemical formation equipment 3, the high-temperature wetting chamber 2, and the stacker 4 can be referred to Chinese utility model patent CN217822936U.

[0030] In one embodiment, a first blocking and limiting mechanism 9, a second blocking and limiting mechanism 10, and a third blocking and limiting mechanism 11 are sequentially arranged along the conveying direction on the feeding conveyor line 1 to block and limit the material trays carrying battery cells on the feeding conveyor line 1, and the nail removal machine 6 is located between the first blocking and limiting mechanism 9 and the second blocking and limiting mechanism 10; the first blocking and limiting mechanism 9 can block and limit the trays on the feeding conveyor line 1 that are to enter the high-temperature wetting chamber 2, the second blocking and limiting mechanism 10 can block and limit the trays on the feeding conveyor line 1 that are to be nailed, and the third blocking and limiting mechanism 11 can block and limit the trays on the feeding conveyor line 1 that are to be formed.

[0031] In one embodiment, the feeding conveyor line 1 is further provided with a first lifting and transferring mechanism 7 and a second lifting and transferring mechanism 8, and the first lifting and transferring mechanism 7 is located on the side of the first blocking and limiting mechanism 9 away from the nail puller 6, and the second lifting and transferring mechanism 8 is located between the second blocking and limiting mechanism 10 and the third blocking and limiting mechanism 11.

[0032] Specifically, when the first blocking mechanism blocks the limiting pallet, the first lifting and transferring mechanism 7 lifts the pallet upward and separates it from the feeding conveyor line 1. The stacker 4 forks the pallet and sends it into the corresponding storage location in the high-temperature soaking chamber 2 for storage. When the predetermined outbound time is reached, the stacker 4 forks the pallet in the high-temperature soaking chamber 2 and places it back on the first lifting and transferring mechanism 7. The first lifting and transferring mechanism 7 descends and resets, the first blocking mechanism releases its obstruction of the pallet, and the pallet continues to be conveyed into the nail puller 6.

[0033] When the tray is transported to the nail puller 6, the second blocking mechanism is activated and blocks and limits the tray. The nail puller 6 pulls out the glue nails on the outer surface of the battery cell on the tray. Then the second blocking mechanism is released from blocking and limiting the tray so that the tray can continue to be transported forward.

[0034] When the pallet is transported to the second lifting and transfer mechanism 8, the third blocking and limiting mechanism 11 works and blocks and limits the pallet. The second lifting and transfer mechanism 8 lifts the pallet upward and separates it from the feeding conveyor line 1. The stacker 4 forks the pallet and puts it into the corresponding storage position in the formation cabinet for formation.

[0035] Once the scheduled delivery time is reached, the pallet formed by the stacker's four forks is moved to the unloading conveyor line 5 for output.

[0036] In one embodiment, a circulating conveyor line 13 is provided on the side of the feeding conveyor line 1. The circulating conveyor line 13 is equipped with a third lifting and transferring mechanism 12 and a fourth lifting and transferring mechanism 14. The third lifting and transferring mechanism 12 is distributed along the front-back direction with the second lifting and transferring mechanism 8, and the fourth lifting and transferring mechanism 14 is distributed along the front-back direction with the first lifting and transferring mechanism 7. When the battery cell on the tray lifted upward by the second lifting and transferring mechanism 8 fails to be successfully removed, the third lifting and transferring mechanism 12 lifts upward to the same horizontal height as the second lifting and transferring mechanism 8. The pallet is moved to the third lifting and transferring mechanism 12 via the second lifting and transferring mechanism 8. The third lifting and transferring mechanism 12 descends to bring the pallet onto the circulating conveyor line 13 for manual nail removal. When the pallet after nail removal is moved to the fourth transferring mechanism, the fourth lifting and transferring mechanism 14 lifts the pallet upward and raises the first lifting and transferring mechanism 7 to the same horizontal height as the fourth lifting and transferring mechanism 14. The pallet is then moved back to the first lifting and transferring mechanism 7 via the fourth lifting and transferring mechanism 14. The stacker 4 forks the pallet and sends it into the chemical forming equipment 3 for chemical forming operations.

[0037] The design of the circulating conveyor line 13 for manual nail removal in this embodiment is beneficial to improving the efficiency of the entire line, reducing equipment waiting time due to nail removal failure, and improving processing efficiency.

[0038] In one embodiment, the loading end of the unloading conveyor line 5 is provided with a fifth lifting and transfer mechanism 15. When the pallet after the stacker 4 forks up the pallet after the forming operation is moved to the unloading conveyor line 5, the fifth lifting and transfer mechanism 15 is in a lifting state. The stacker 4 moves the pallet onto the fifth lifting and transfer mechanism 15, and uses the descent of the fifth lifting and transfer mechanism 15 to make the pallet fall onto the unloading conveyor line 5 for outward transport.

[0039] In one embodiment, the first lifting and transfer mechanism 7, the second lifting and transfer mechanism 8, the third lifting and transfer mechanism 12, the fourth lifting and transfer mechanism 14, and the fifth lifting and transfer mechanism 15 are existing mature equipment. In another embodiment, the lifting and transfer mechanism in Chinese invention patent CN116666767A can be selected.

[0040] In one embodiment, the feeding conveyor line 1, the unloading conveyor line 5, and the circulating conveyor line 13 are all roller conveyor lines.

[0041] In one embodiment, the first blocking limit mechanism 9, the second blocking limit mechanism 10, and the third blocking limit mechanism 11 are all pneumatic blocking limit mechanisms. In another embodiment, the pneumatic blocking limit mechanism may be a blocking cylinder.

[0042] In one embodiment, the highest position of the first lifting and transferring mechanism 7 and the second lifting and transferring mechanism 8 is higher than the horizontal height of the conveying surface of the feeding conveyor line 1, and the lowest position is the same as the horizontal height of the conveying surface of the feeding conveyor line 1.

[0043] In one embodiment, the highest position of the third lifting and transferring mechanism 12 and the fourth lifting and transferring mechanism 14 is higher than the horizontal height of the conveying surface of the circulating conveyor line 13, and the lowest position is the same as the horizontal height of the conveying surface of the circulating conveyor line 13.

[0044] In one embodiment, the highest position of the fifth lifting and transferring mechanism 15 is higher than the horizontal height of the conveying surface of the unloading conveyor line 5, and the lowest position is the same as the horizontal height of the conveying surface of the unloading conveyor line 5.

[0045] The above descriptions are merely some embodiments of this application and do not limit the implementation methods and protection scope of this application. Those skilled in the art should realize that any equivalent substitutions and obvious changes made using the description and illustrations of this application should be included within the protection scope of this application.
