Referring to fig. 1, in an embodiment of the present utility model, a tab welding system 10 is provided, where the tab welding system 10 can provide a location for welding a battery cell 12 and a tab 11, so as to ensure stability of the tab 11 during welding to the battery cell 12, and further improve welding accuracy of the tab 11, so as to improve yield.

In the present embodiment, referring to fig. 1 and 2 in combination, the interposer bonding system 10 includes a base 100, an air extraction mechanism 200, a pressure release mechanism 300, and an interposer positioning device 13. The adaptor positioning device 13, the air extraction mechanism 200 and the pressure release mechanism 300 are all disposed on the base 100, and the base 100 can provide a bearing function for the adaptor positioning device 13, the air extraction mechanism 200 and the pressure release mechanism 300.

In this embodiment, referring to fig. 3 and 4 in combination, the adaptor plate positioning device 13 includes a base 400, an extraction valve 500, a pressure release valve 600 and a holding cylinder 700. The upper surface of the base 400 is provided with an assembly groove 420 adapted to the adapter piece 11; in the case where the adapter plate 11 is placed on the base 400, the adapter plate is fitted into the fitting groove 420, and the fitting groove 420 can provide a restraining effect to the adapter plate 11 through its peripheral wall, preventing displacement of the adapter plate 11 during welding. A channel 410 for accessing the assembly groove 420 is formed in the base 400; the passage 410 forms a first outlet 411 and a second outlet 412 on both sides of the housing 400, respectively. The extraction valve 500 is disposed at the first outlet 411; the extraction valve 500 is used to open the first outlet 411 when the extraction connector 210 is connected, and also to close the first outlet 411 when the extraction connector 210 is disconnected. When the air extraction connector 210 of the air extraction mechanism 200 is connected to the air extraction valve 500, the air extraction connector 210 can prop up the closed structure of the air extraction valve 500, so as to achieve the purpose of being connected to the first outlet 411, and then air can be extracted from the channel 410, and negative pressure is formed in the channel 410; in the case that the suction connector 210 is separated from the suction valve 500, the closing structure of the suction valve 500 returns to the initial position to close the first outlet 411. The pressure release valve 600 is disposed at the second outlet 412; the pressure relief valve 600 is used to open the second outlet 412 when the pressure relief member 310 is engaged and also to close the second outlet 412 when the pressure relief member 310 is disengaged. Under the condition that the pressure release member 310 of the pressure release mechanism 300 is connected to the pressure release valve 600, the closed structure of the pressure release valve 600 can be pushed open by the pressure release member 310, so that the second outlet 412 is communicated with the outside, and the outside air can conveniently enter the channel 410, so that the air pressure in the channel 410 is the same as the atmospheric pressure, and the purpose of pressure release is achieved.

In addition, the holding cylinder 700 includes a cylinder body 710, a piston 720, and an elastic member 730; the cylinder 710 is connected to the base 400, and a cavity communicating with the channel 410 is provided inside the cylinder 710; the piston 720 is at least partially movably disposed in the cavity for reducing or increasing the volume of the cavity access channel 410 when moving relative to the cylinder 710; the cylinder 710 and the piston 720 are both connected to the elastic member 730, and when the piston 720 moves relative to the cylinder 710 to reduce the volume of the cavity access channel 410, the elastic member 730 is driven to elastically deform.

In the above, after the adaptor 11 is placed in the assembly groove 420, the suction connector 210 is connected to the suction valve 500 to form negative pressure in the channel 410, so that negative pressure can be formed in the assembly groove 420, the adsorption positioning of the adaptor 11 can be effectively completed, the positioning precision of the adaptor 11 is improved, and the stable and accurate welding of the adaptor 11 is ensured. Meanwhile, due to the arrangement of the holding cylinder 700, under the condition that the channel 410 forms negative pressure, the cavity in the cylinder 710 forms negative pressure at the same time, so that the piston 720 can be driven to move relative to the cylinder 710 to drive the elastic member 730 to elastically deform. After the suction connector 210 is separated from the suction valve 500, the elastic restoring action of the elastic member 730 can provide the force for increasing the volume of the cavity access channel 410 to the piston 720, so as to enable the channel 410 to maintain the negative pressure state, even if the channel 410 has a small amount of air leakage, the negative pressure state in the channel 410 can be maintained by the elastic action of the elastic member 730, so as to ensure that the rotating sheet 11 can be stably adsorbed in the assembly groove 420. Based on this, the purpose of improving the technical problem that the welding effect is affected due to the poor positioning effect of the switching piece 11 in the prior art can be achieved.

That is, negative pressure can be formed in the passage 410 by the air suction mechanism 200, so that the transfer sheet 11 in the assembly groove 420 can be sucked through the opening of the passage 410 into the assembly groove 420, thereby ensuring the assembly stability of the transfer sheet 11 in the assembly groove 420 and improving the positioning accuracy and the positioning stability of the transfer sheet 11. After the welding of the adapter piece 11 and the battery cell 12 is completed, the pressure release of the channel 410 is realized through the pressure release mechanism 300, so that the negative pressure in the channel 410 can be eliminated, and the absorption of the opening of the channel 410 connected to the assembly groove 420 to the adapter piece 11 is canceled, so that the battery cell 12 and the adapter piece 11 can be conveniently detached. Based on this, the object of improving the technical problem of the prior art that the welding effect is affected due to the poor positioning effect of the switching piece 11 can be achieved.

Optionally, in some embodiments of the present utility model, as shown in fig. 3 and 6, the extraction valve 500 includes an inner cavity 520, a resilient structure 530, a sealing bead 540, a sealing ring 550, and an outer cavity 510; the outer cavity 510 is provided with a cavity, a section of the outer cavity 510, which is inserted into the channel 410, is provided with a through hole, the inner cavity 520 is inserted into the outer cavity 510 from the other end of the outer cavity 510, and the sealing ring 550 is pressed between the inner cavity 520 and the outer cavity 510. A cavity is arranged in the inner cavity 520, and through holes are formed at two ends of the inner cavity 520; the elastic structure 530 and the sealing steel ball 540 are disposed in the cavity of the inner cavity 520, and the sealing steel ball 540 is abutted against one end of the inner cavity 520, which is close to the through hole on the outer cavity 510, under the elastic action of the elastic structure 530. When the air suction connector 210 is connected to the through hole outside the inner cavity 520 and air is sucked, negative pressure is formed in the cavity of the inner cavity 520 to overcome the elastic action of the elastic structure 530, so that the sealing steel ball 540 opens the through hole inside the inner cavity 520, and air in the channel 410 can be sucked, so that negative pressure is formed in the channel 410. When the suction connector 210 is separated, the sealing steel ball 540 is propped against the through hole on the inner side of the inner cavity 520 again under the action of the elastic structure 530 and seals the through hole, and meanwhile, due to the formation of negative pressure in the channel 410, the sealing steel ball 540 further seals the through hole, so that the purpose of sealing the first outlet 411 can be achieved.

In addition, the relief valve 600 may employ a valve. Of course, in other embodiments, other check valves may be used with the pressure relief valve 600.

In this embodiment, in order to facilitate the adsorption of the adaptor piece 11, the adaptor piece positioning device 13 further includes a suction nozzle 800, the suction nozzle 800 is disposed in the assembly slot 420, and the inner space of the suction nozzle 800 is connected to the channel 410; the suction end of the suction nozzle 800 is flush with the bottom wall of the fitting groove 420 for sucking the adapter plate 11. The suction nozzle 800 may be made of a flexible material, and in the case that negative pressure is formed in the channel 410, the suction nozzle 800 can conveniently and effectively adsorb the switching piece 11 through flexible deformation, so as to ensure that the switching piece 11 is stably adsorbed inside the assembly groove 420.

Of course, in other embodiments of the present utility model, the arrangement of the suction nozzle 800 may be eliminated. In the case that negative pressure is formed in the passage 410, the transfer sheet 11 can be directly sucked through the opening of the passage 410 into the fitting groove 420.

In the present embodiment, the passage 410 penetrates the housing 400 along a straight line, and the first outlet 411 and the second outlet 412 are formed on opposite sides of the housing 400. Based on this, the air extraction mechanism 200 and the pressure release mechanism 300 can be respectively arranged at two opposite sides of the seat 400, so that the air extraction mechanism 200 can conveniently connect the air extraction joint 210 to the air extraction valve 500, the pressure release mechanism 300 can conveniently connect the pressure release member 310 to the pressure release valve 600, and further the mutual influence of the air extraction mechanism 200 and the pressure release mechanism 300 can be prevented.

In addition, it should be noted that, in the embodiment of the present utility model, when the base 400 is assembled to the base 100, the base 400 can move along a predetermined direction, and based on this, the air extraction mechanism 200 and the pressure release mechanism 300 are respectively disposed on two opposite sides of the base 400, so that the air extraction mechanism 200 and the pressure release mechanism 300 can be prevented from affecting the movement of the base 400.

In the case of fig. 4 as an example, the opening direction of the passage 410 is a penetrating direction along the width direction of the housing 400, and based on this, the first outlet 411 and the second outlet 412 are provided on both sides of the housing 400 in the width direction, respectively. It should be appreciated that in other embodiments of the present utility model, other path arrangements may be used for the path of opening of the channel 410. For example, the channel 410 opens onto the base 400 along a fold line path; for another example, the channel 410 may open along a curved path, etc.

Further, in the embodiment of the present utility model, as shown in fig. 5, two assembly grooves 420 are formed on the base 400, and the two assembly grooves 420 are arranged at intervals along the width direction of the base 400. In this way, the two fitting grooves 420 can be communicated with the passage 410 at the same time, and the adapter pieces 11 in the two fitting grooves 420 can be simultaneously adsorbed when negative pressure is formed in the passage 410. It can be seen that, the opening of the channel 410 along the straight path is convenient, so that the channel 410 can pass through the two assembly slots 420, and is convenient to be connected with both the two assembly slots 420, thereby facilitating the adsorption of the adaptor 11 in the two assembly slots 420.

It should be understood that in other embodiments of the present utility model, the opening path of the channel 410 may be adjusted according to the actual situation of the assembly slots 420, so that the channel 410 may communicate with two assembly slots 420 at the same time.

Of course, in other embodiments of the present utility model, two independent channels 410 may be formed for the two fitting grooves 420 to independently control the adsorption of the transfer sheet 11 in the two fitting grooves 420.

In the present embodiment, the cylinder body 710 is coupled to the passage 410 through the adapter tube 740, and the adapter tube 740 and the holding cylinder 700 are provided at the lower surface of the housing 400. By disposing both the holding cylinder 700 and the transfer tube 740 below the base 400, it is possible to prevent the transfer tube 740 and the holding cylinder 700 from affecting the welding operation of the upper surface of the base 400, ensuring that the welding operation is performed efficiently.

In this embodiment, the piston 720 has a rod portion extending out of the cylinder 710 and a plug portion disposed in the cylinder 710, wherein the plug portion is movably disposed in the cavity to reduce or increase the volume of the cavity access channel 410 when moving relative to the cylinder 710; the stem then follows the plug. The elastic member 730 is a spring, and the elastic member 730 is sleeved on the rod, and two ends of the elastic member 730 respectively support the cylinder 710 and the limiting structure on the end of the rod. In the case where the rod portion follows the plug portion, the limit structure may move relative to the cylinder 710; when the plug portion reduces the volume of the cavity access channel 410, the limiting structure and the cylinder 710 can jointly compress the elastic member 730, so that the elastic member 730 is elastically deformed; based on this, after the evacuation mechanism 200 is removed, the plug portion can have a tendency to increase the volume of the cavity access passage 410 by the elastic restoring action of the elastic member 730, and thus the negative pressure in the passage 410 can be maintained to stably adsorb the switching piece 11. In the case that the negative pressure of the channel 410 is released by the pressure release mechanism 300, the elastic member 730 drives the rod portion to move by the elastic restoring action, and the plug portion increases the volume of the cavity access channel 410.

In the present embodiment, referring to fig. 3 and 5 in combination, a plurality of positioning blocks 440 are further protruded on the upper surface of the base 400, and the plurality of positioning blocks 440 enclose a positioning space 441 for placing the power supply core 12; the fitting groove 420 is disposed outside the positioning space 441. The assembly groove 420 is disposed adjacent to the positioning space 441, so that, when the battery cell 12 is placed in the positioning space 441, a position on the battery cell 12 matching with the switching piece 11 can extend out of the positioning space 441 to correspond to the switching piece 11, so as to facilitate welding of the switching piece 11 to the battery cell 12. The plurality of positioning blocks 440 can provide a limiting function for the battery cells 12, so as to ensure that the battery cells 12 can be kept stable in the welding process, and improve the welding yield.

Alternatively, in the embodiment of the present utility model, the plurality of positioning blocks 440 enclose two positioning spaces 441 on the upper surface of the seat body 400, and the assembly groove 420 is disposed between the two positioning spaces 441. Thus, two cells 12 may be simultaneously placed on the socket body 400 to simultaneously complete the welding of the two cells 12. At the same time, the fitting grooves 420 are provided in the two positioning spaces 441, so that the soldering of the tab 11 to the cell 12 can be facilitated.

Of course, in other embodiments of the present utility model, the number of positioning spaces 441 may be one.

In order to further improve the stability of the battery core 12 placed in the positioning space 441, the base 400 is further provided with an adsorption hole 430, and the adsorption hole 430 is communicated with the positioning space 441. The suction holes 430 may generate negative pressure to suck the cells 12 to ensure the stability of the cells 12. It should be noted that, since the mass of the battery cell 12 is larger than that of the adaptor 11, the suction hole 430 may use an independent negative pressure generating mechanism to suck the battery cell 12. Of course, in some embodiments of the present utility model, the adsorption hole 430 may be connected to the passage 410.

In the present embodiment, referring to fig. 1 and 2, a slide rail 110 is disposed on a base 100, and at least an adsorption station, a welding station and a disassembling station are formed along an extending path of the slide rail 110. The base 400 is slidably connected to the slide rail 110, so that the base 400 sequentially passes through an adsorption station, a welding station and a detaching station. The base 400 is slidably mounted to the slide rail 110 through a mounting table and a slide table. The air extraction mechanism 200 is disposed at the suction station, and is used for driving the air extraction connector 210 of the air extraction mechanism 200 to be connected to the air extraction valve 500 when the seat 400 moves to the suction station, and driving the air extraction connector 210 to be separated from the air extraction valve 500 after air extraction is completed. The pressure release mechanism 300 is disposed at the disassembling station, and is used for driving the pressure release member 310 of the pressure release mechanism 300 to access the pressure release valve 600 when the seat 400 moves to the disassembling station, and driving the pressure release member 310 to release from the pressure release valve 600 after the pressure release is completed.

Based on this, during the adsorption station, the suction connector 210 can be driven by the suction mechanism 200 to be connected to the suction valve 500, so that the negative pressure is formed in the channel 410 by the gas in the suction channel 410, and the adaptor 11 in the assembly groove 420 can be adsorbed by the suction cup. After the extraction joint 210 is removed, the piston 720 has a tendency to extract the gas in the channel 410 due to the elastic restoring action of the elastic member 730 in the holding cylinder 700, so that the negative pressure state is continuously maintained in the channel 410, and the stability of the adsorption adapter 11 can be ensured. When in a welding station, the switching piece 11 and the battery cell 12 can be welded, and the switching piece 11 can be accurately welded to the battery cell 12 due to the fact that the switching piece 11 is stably adsorbed in the assembly groove 420, so that the welding yield of the switching piece 11 is improved. When the station is disassembled, the pressure release mechanism 300 can drive the pressure release member 310 to be connected to the pressure release valve 600, the pressure release valve 600 opens the second outlet 412 to enable the channel 410 to be communicated with the external atmosphere, so that the negative pressure in the channel 410 can be eliminated, the adsorption force to the adapter 11 can be eliminated, and the adapter 11 can be conveniently disassembled.

The air extraction mechanism 200 may include a driving cylinder and an air extraction connector 210, where the driving cylinder may drive the air extraction connector 210 to move, so as to facilitate the air extraction connector 210 to be connected to or disconnected from the air extraction valve 500; the suction connector 210 may be connected to a negative pressure device, so that the suction connector 210 can conveniently suck the gas in the channel 410 when connected to the suction valve 500, so as to form a negative pressure in the channel 410. In addition, the pressure release mechanism 300 may include a driving cylinder and a thimble, where the driving cylinder may drive the thimble to move to access or release the pressure release valve 600.

Further, in the present embodiment, the sliding rail 110 extends along a circumferential path. That is, the base 400 can slide on the slide rail 110 along a circumferential path, so that the receiving, welding and removing of the transferring pieces 11 are repeatedly performed through the adsorbing station, the welding station and the removing station, and the welding operation of a large number of transferring pieces 11 can be sequentially completed, thereby improving the throughput.

In addition, the patch welding system 10 includes a plurality of patch positioning devices 13, and a plurality of sockets 400 are movably connected to the sliding rail 110. By adopting the arrangement mode of the plurality of transfer sheet positioning devices 13, the adsorption station, the welding station and the disassembly station can be simultaneously put into use, when one transfer sheet 11 executes adsorption operation, the other transfer sheet 11 executes welding operation at the welding station, and meanwhile, the other transfer sheet 11 executes disassembly operation at the disassembly station, and of course, more stations can be arranged to synchronously execute more processing operations; multiple preparation stations may also be provided to facilitate preparation operations and the like.

In summary, in the patch positioning device 13 and the patch welding system 10 provided in the embodiments of the present utility model, after the patch 11 is placed in the assembly groove 420, the suction connector 210 is connected to the suction valve 500 to form negative pressure in the channel 410, so that negative pressure can be formed in the assembly groove 420, thereby effectively completing the adsorption positioning of the patch 11, improving the positioning accuracy of the patch 11, and ensuring stable and accurate welding of the patch 11. Meanwhile, due to the arrangement of the holding cylinder 700, under the condition that the channel 410 forms negative pressure, the cavity in the cylinder 710 forms negative pressure at the same time, so that the piston 720 can be driven to move relative to the cylinder 710 to drive the elastic member 730 to elastically deform. After the suction connector 210 is separated from the suction valve 500, the elastic restoring action of the elastic member 730 can provide the force for increasing the volume of the cavity access channel 410 to the piston 720, so as to enable the channel 410 to maintain the negative pressure state, even if the channel 410 has a small amount of air leakage, the negative pressure state in the channel 410 can be maintained by the elastic action of the elastic member 730, so as to ensure that the rotating sheet 11 can be stably adsorbed in the assembly groove 420. Based on this, the purpose of improving the technical problem that the welding effect is affected due to the poor positioning effect of the switching piece 11 in the prior art can be achieved. The plurality of transfer sheet positioning devices 13 are slidably arranged on the sliding rail 110, so that the plurality of transfer sheets 11 sequentially pass through the adsorption station, the welding station and the disassembly station one by one, each station is simultaneously put into operation, the welding efficiency of the transfer sheets 11 is improved, and the yield can be improved. And the sliding rail 110 is set to be a circumferential path, so that the plurality of rotating sheet positioning devices 13 can circularly run on the sliding rail 110, the continuous proceeding of a welding process can be facilitated, and the working efficiency is improved.

The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the scope of the present utility model should be included in the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
