Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production, in particular to a high-temperature infiltration and formation integrated device with a nail pulling function for lithium batteries. Background Art

[0002] The high-temperature soaking and formation processes in the lithium battery industry are indispensable links in the battery production process. The traditional layout method is often based on the process flow, that is, the pallets carrying the battery cells enter the high-temperature soaking warehouse, undergo high-temperature soaking within the specified process time, and are then taken out by the stacker and sent to the formation workshop via the conveyor line to complete the formation process. Before the battery cells are formed, the liquid injection glue pins on the surface of the battery cells need to be pulled out before the formation operation can be carried out.

[0003] 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 infiltration warehouse and the chemical formation equipment are two independent workshops, so separate stackers need to be configured for high-temperature infiltration and chemical formation, resulting in space waste and increased equipment investment. Utility Model Content

[0004] In view of the above problems existing in existing production operations, the present invention aims to provide a high-temperature infiltration and formation integrated device for lithium batteries with a nail removal function, which has a simple structure, high efficiency and low cost.

[0005] The specific technical solutions are as follows:

[0006] A high-temperature impregnation and formation integrated device for lithium batteries with a nail-pulling function comprises a loading conveyor line, a unloading conveyor line, formation equipment arranged on the loading conveyor line and the unloading conveyor line, a high-temperature impregnation warehouse arranged on the side of the formation equipment, and a stacking machine arranged between the high-temperature impregnation warehouse and the formation equipment. The device comprises: a nail-pulling machine installed on the loading conveyor line for pulling out glue-injected nails on the surface of lithium battery cells after high-temperature impregnation.

[0007] As a further improvement and optimization of this solution, a first blocking and limiting mechanism, a second blocking and limiting mechanism and a third blocking and limiting mechanism are sequentially arranged along the conveying direction on the loading conveyor line to block and limit the material tray carrying battery cells on the loading conveyor line, and the nail puller is arranged between the first blocking and limiting mechanism and the second blocking and limiting mechanism.

[0008] As a further improvement and optimization of this solution, a first lifting and transferring mechanism and a second lifting and transferring mechanism are also provided on the loading conveyor line, and the first lifting and transferring mechanism is provided on the side of the first blocking and limiting mechanism away from the nail pulling machine, and the second lifting and transferring mechanism is provided between the second blocking and limiting mechanism and the third blocking and limiting mechanism.

[0009] As a further improvement and optimization of this solution, a circulating conveyor line is set on the side of the loading conveyor line, and the circulating conveyor line is provided with a third jacking and transferring mechanism and a fourth jacking and transferring mechanism. The third jacking and transferring mechanism and the second jacking and transferring mechanism are distributed along the front-to-back direction, and the fourth jacking and transferring mechanism and the first jacking and transferring mechanism are distributed along the front-to-back direction.

[0010] As a further improvement and optimization of this solution, a fifth lifting and transferring mechanism is provided at the loading end of the unloading conveyor line.

[0011] As a further improvement and optimization of this solution, the loading conveyor line, the unloading conveyor line, and the circulating conveyor line are all roller conveyor lines.

[0012] As a further improvement and optimization of this solution, 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.

[0013] As a further improvement and optimization of this solution, the highest level of the first lifting and transferring mechanism and the second lifting and transferring mechanism is higher than the level of the conveying surface of the loading conveyor line, and the lowest level is consistent with the level of the conveying surface of the loading conveyor line.

[0014] As a further improvement and optimization of this solution, the highest level of the third lifting and transferring mechanism and the fourth lifting and transferring mechanism is higher than the level of the conveying surface of the circulating conveyor line, and the lowest level is consistent with the level of the conveying surface of the circulating conveyor line.

[0015] As a further improvement and optimization of this solution, the highest level of the fifth lifting and transferring mechanism is higher than the level of the conveying surface of the unloading conveyor line, and the lowest level is consistent with the level of the conveying surface of the unloading conveyor line.

[0016] Compared with the prior art, the above technical solution has the following positive effects:

[0017] (1) The utility model integrates the high-temperature infiltration warehouse and the chemical forming cabinet on both sides of the stacker lane when the efficiency requirement of the entire line is not high. After the high-temperature infiltration is completed, the nails are pulled out by a nail pulling machine arranged on the feeding conveyor line, and then enter the chemical forming cabinet, which is more in line with the application scenario in actual production.

[0018] (2) The integrated arrangement of the medium and high temperature infiltration warehouse and the chemical forming cabinet in the present invention allows the use of fewer stackers without increasing the floor space, which is beneficial to improving the working efficiency of the stackers.

[0019] (3) The design of the circulating conveyor line for manual nail pulling in the present invention is conducive to improving the efficiency of the entire line, reducing the equipment waiting time caused by nail pulling failure, and improving processing efficiency.

[0025] Figure 1This is a schematic diagram of the structure of a high-temperature infiltration and formation integrated device for lithium batteries with a nail removal function. Figure 1 As shown, a preferred embodiment of a high-temperature impregnation and formation integrated device for lithium batteries with a nail pulling function is shown, comprising a feeding conveyor line 1, a feeding conveyor line 5, a formation device 3 arranged on the feeding conveyor line 1 and the feeding conveyor line 5, a high-temperature impregnation warehouse 2 arranged on the side of the formation device 3, and a stacking machine 4 arranged between the high-temperature impregnation warehouse 2 and the formation device 3, including: a nail pulling machine 6 is installed on the feeding conveyor line 1, which is used to pull out the glue injection nails on the surface of the lithium battery cell after high-temperature impregnation, and the tray carrying the battery cell passes through The loading conveyor line 1 moves forward, and the stacking machine 4 forks the pallet and sends it to the corresponding storage location in the high-temperature infiltration warehouse 2 for storage. When the predetermined outbound time is reached, the stacking machine 4 forks the pallet in the high-temperature infiltration warehouse 2 and puts it into the loading conveyor line 1 and continues to transport it forward through the nail puller 6 and the nail puller 6 pulls out the glue injection nails on the outer surface of the battery cell on the pallet. The pallet carrying the battery cell continues to be transported forward through the loading conveyor line 1 and outputs the nail puller 6. The stacking machine 4 forks the pallet again and puts it into the corresponding storage location in the formation cabinet for formation.

[0026] In this application, when the efficiency requirements of the entire line are not high, the high-temperature infiltration warehouse 2 and the chemical forming cabinet are integrated on both sides of the stacker aisle, and after the high-temperature infiltration is completed, the nails are pulled out by the nail puller 6 arranged on the feeding conveyor line 1, and then enter the chemical forming cabinet, which is more in line with the application scenario in actual production.

[0027] In the present application, the high-temperature infiltration warehouse 2 and the formation cabinet are integrated so that fewer stackers can be used without increasing the floor space, which is beneficial to improving the working efficiency of the stackers.

[0028] Specifically, the nail pulling machine 6, the loading conveyor line 1, the unloading conveyor line 5, the forming equipment 3, the high-temperature infiltration warehouse 2 and the stacking machine 4 are all existing mature equipment. The nail pulling control method of the nail pulling machine 6 can refer to the Chinese invention patent CN116666767A, and the loading conveyor line 1, the unloading conveyor line 5, the forming equipment 3, the high-temperature infiltration warehouse 2 and the stacking machine 4 can refer to the Chinese utility model patent CN217822936U.

[0029] Furthermore, as a preferred 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 loading conveyor line 1, which are used to block the tray carrying battery cells on the loading conveyor line 1, and the nail pulling machine 6 is arranged 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 the tray on the loading conveyor line 1 waiting to enter the high-temperature infiltration warehouse 2, the second blocking and limiting mechanism 10 can block the tray on the loading conveyor line 1 waiting to be nailed out, and the third blocking and limiting mechanism 11 can block the tray on the loading conveyor line 1 waiting to be formed.

[0030] Furthermore, as a preferred embodiment, a first lifting and transferring mechanism 7 and a second lifting and transferring mechanism 8 are further provided on the feeding conveyor line 1, and the first lifting and transferring mechanism 7 is provided 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 provided between the second blocking and limiting mechanism 10 and the third blocking and limiting mechanism 11;

[0031] Specifically, when the first blocking mechanism blocks the limited pallet, the first lifting and transferring mechanism 7 lifts the pallet upward and separates it from the feeding conveyor line 1. The stacking machine 4 forks the pallet and sends it to the corresponding storage location in the high-temperature infiltration warehouse 2 for storage. When the predetermined outbound time is reached, the stacking machine 4 forks the pallet in the high-temperature infiltration warehouse 2 and places it on the first lifting and transferring mechanism 7 again. The first lifting and transferring mechanism 7 descends and resets, and the first blocking mechanism releases the obstruction on the pallet, and the pallet continues to be transported to the nail extractor 6.

[0032] When the pallet is transported to the nail puller 6, the second blocking mechanism is activated and blocks the pallet. The nail puller 6 pulls out the glue injection nails on the outer surface of the battery cell on the pallet. Then the second blocking mechanism releases the blocking limit on the pallet, so that the pallet can continue to be transported forward.

[0033] When the pallet is transported to the second lifting and transferring mechanism 8, the third blocking and limiting mechanism 11 works and blocks the limited pallet. The second lifting and transferring mechanism 8 lifts the pallet upward and separates it from the feeding conveyor line 1. The stacking machine 4 forks the pallet and places it in the corresponding storage position in the forming cabinet for forming.

[0034] When the scheduled delivery time is reached, the stacking machine 4 picks up the formed pallet and moves it to the unloading conveyor line 5 for delivery.

[0035] Furthermore, as a preferred embodiment, a circulating conveyor line 13 is set on the side of the feeding conveyor line 1, and the circulating conveyor line 13 is provided with a third lifting and transferring mechanism 12 and a fourth lifting and transferring mechanism 14. The third lifting and transferring mechanism 12 and the second lifting and transferring mechanism 8 are distributed along the front-to-back direction, and the fourth lifting and transferring mechanism 14 and the first lifting and transferring mechanism 7 are distributed along the front-to-back direction. When the battery cell on the tray lifted up by the second lifting and transferring mechanism 8 fails to be nailed out, the third lifting and transferring mechanism 12 lifts the battery cell at the same level as the second lifting and transferring mechanism 8 upwards. The pallet is moved to the third lifting and transferring mechanism 12 through the second lifting and transferring mechanism 8, and the third lifting and transferring mechanism 12 is lowered so that the pallet will be moved to 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 makes the first lifting and transferring mechanism 7 rise to the same horizontal height as the fourth lifting and transferring mechanism 14. The pallet is moved to the first lifting and transferring mechanism 7 again through the fourth lifting and transferring mechanism 14, and the stacker 4 forks the pallet and sends it to the forming equipment 3 for forming operation.

[0036] The design of the circulating conveyor line 13 for manual nail pulling in this embodiment is conducive to improving the efficiency of the entire line, reducing the equipment waiting time caused by nail pulling failure, and improving processing efficiency.

[0037] Furthermore, as a preferred embodiment, a fifth lifting and transferring mechanism 15 is provided at the loading end of the unloading conveyor line 5. When the stacking machine 4 forks the pallet after the formation operation and moves it to the unloading conveyor line 5, the fifth lifting and transferring mechanism 15 is in a lifting state, and the stacking machine 4 moves the pallet to the top of the fifth lifting and transferring mechanism 15, and uses the descent of the fifth lifting and transferring mechanism 15 to make the pallet fall onto the unloading conveyor line 5 for outward transportation.

[0038] Preferably, the first lifting and transferring mechanism 7, the second lifting and transferring mechanism 8, the third lifting and transferring mechanism 12, the fourth lifting and transferring mechanism 14, and the fifth lifting and transferring mechanism 15 are existing mature equipment. In one embodiment, the lifting and transferring mechanism in Chinese invention patent CN116666767A can be selected.

[0039] Furthermore, as a preferred embodiment, the loading conveyor line 1, the unloading conveyor line 5, and the circulating conveyor line 13 are all roller conveyor lines.

[0040] Furthermore, as a preferred embodiment, the first blocking and limiting mechanism 9, the second blocking and limiting mechanism 10, and the third blocking and limiting mechanism 11 are all pneumatic blocking and limiting mechanisms. In one embodiment, the pneumatic blocking and limiting mechanism can be a blocking cylinder.

[0041] Furthermore, as a preferred embodiment, the highest level of the first lifting and transferring mechanism 7 and the second lifting and transferring mechanism 8 is higher than the level of the conveying surface of the loading conveyor line 1, and the lowest level is consistent with the level of the conveying surface of the loading conveyor line 1.

[0042] Furthermore, as a preferred embodiment, the highest level of the third lifting and transferring mechanism 12 and the fourth lifting and transferring mechanism 14 is higher than the level of the conveying surface of the circulating conveyor line 13, and the lowest level is consistent with the level of the conveying surface of the circulating conveyor line 13.
