Description

Technical Field

[0001] The invention relates to the technical field of soft-pack battery core production, in particular to a special machine for defusing air bags. Background Art

[0002] The battery cell is an energy storage unit with a high energy density. It can store as much energy as possible to give electric vehicles a longer range. Damage to any battery cell will cause damage to the entire battery pack. With the vigorous development of new energy and the continuous expansion of the power battery industry, the production standards, quality and safety control of battery cells are becoming increasingly strict and mature. A standard battery cell appearance size that meets the requirements plays a great role in improving the speed and ensuring the quality of the entire battery cell production process.

[0003] The production process of soft-pack batteries involves multiple processes such as handling, testing, and formation. The handling process requires the robot to pick up the air bag of the soft-pack battery and place it in the corresponding slot of the test fixture. In the existing process, since the robot can carry multiple soft-pack lithium batteries at a time, the soft-pack lithium batteries need to be placed in a tray before handling. There are many placement slots arranged in the tray. After the soft-pack lithium battery is placed in the placement slot, it can be limited in the placement slot. At the same time, the air bag of the soft-pack battery core will be exposed outside the placement slot and clamped by the robot, so that the robot can clamp multiple soft-pack lithium batteries at a time.

[0004] However, in the production process of soft-pack batteries, the air bags of the soft-pack batteries loaded in the tray are crooked, tilted to both sides and irregular. Currently, manual means can only be used to straighten the air bags to enable the robot station in the next process to automatically grab the soft-pack batteries from the tray. However, this process is time-consuming and labor-intensive, and increases labor costs. Summary of the invention

[0059] like Figure 1-10As shown, an embodiment of the present invention provides a deflation bag machine, which is used for loading a plurality of soft-pack battery cells along the second direction of the tray 10 before the robot station grabs the soft-pack battery cell out of the tray 10, and the main body of the soft-pack battery cell is located in the tray (existing structure), and the air bag 11 is exposed from the tray 10, which is convenient for the robot to grab. The machine specifically includes a transport device 1, a tray positioning device 2 and a straightening device 3, wherein the transport device 1 is used to transport the tray 10 loaded with a plurality of soft-pack battery cells. In this embodiment, the transport device 1 is a roller transport The device is provided and transported along a first direction, wherein the first direction is parallel to the length direction of the air bags 11 of the soft-pack battery cells exposed above the pallet 10; the pallet positioning device 2 is installed on the mounting frame of the transport device 1, and is used to stop the pallet 10 transported on the transport device 1, and position the pallet 10 to the straightening area; the straightening device 3 is used to straighten the soft-pack battery cell air bags 11 exposed above the pallet 10 in the straightening area along the first direction, and the straightening device 3 contacts with multiple soft-pack battery cell air bags 11 at a time, so as to straighten them in batches. Through the cooperation of the three devices of the transport device 1, the pallet positioning device 2 and the straightening device 3, the soft-pack battery cell air bag 11 in the pallet 10 can be automatically straightened, and multiple soft-pack battery cells can be straightened in the pallet 10 at the same time, which can reduce labor costs and effectively improve the battery cell production efficiency and battery cell quality. After straightening, the robot can clamp stably, making the robot's clamping and grasping process accurate, and the air bag 11 will not be wrinkled due to grasping.

[0060] Specifically, Figure 3-6As shown, the straightening device 3 includes a first mounting frame 31, a first mounting plate 32, a second mounting plate 33, a first driving assembly 34, a second driving assembly 35, a third driving assembly 36 and a clamping assembly 37, wherein the first mounting plate 32 is located above the second mounting plate 33, and the first mounting plate 32 is arranged on the first mounting frame 31; specifically, the first driving assembly 34 is located on the first mounting plate 32, and the output end is vertically downward, and is connected to the second mounting plate 33, so that the second mounting plate 33 moves in the vertical direction; the lower end of the clamping assembly 37 is provided with a plurality of clamping openings 374, and the plurality of clamping openings 374 are distributed along the first direction, and the opening direction of the clamping openings 374 is The second direction is arranged along the second direction, wherein the second direction is parallel to the length direction of the air bag 11 of the soft-pack battery cell exposed above the tray 10, and the first direction is perpendicular to the second direction and is located on the same horizontal plane, so that multiple air bags 11 in the length direction can enter the multiple clamping openings 374 in the vertical direction; correspondingly, the second drive component 35 is arranged on the second mounting plate 33, wherein the second drive component 35, the clamping component 37 and the third drive component 36 are all arranged in two, and are distributed along the second direction, and the output ends of the two second drive components 35 are respectively connected to the two clamping components 37, so that the two clamping components 37 are close to or along the second direction. The two third drive components 36 respectively open or close the clamping openings 374 in the two clamping components 37 along the first direction, so that the second drive component 35, the clamping component 37 and the third drive component 36 form two groups to clamp and straighten the airbag 11. Specifically, under the action of the first drive component 34, the clamping component 37 moves downward, so that the airbag 11 of the same soft-pack battery cell enters the two clamping openings 374 of the two clamping components 37. Of course, initially driven by the two second drive components 35, the two clamping components 37 are close to each other so that the two clamping openings 374 in the two clamping components 37 are located in the middle of the same airbag 11. Then, under the action of the two third drive components 36, the clamping openings 374 in the two clamping components 37 are closed along the first direction to clamp the air bag 11. Then, driven by the two second drive components 35, the two clamping components 37 move away from each other along the second direction to straighten the air bag 11. After straightening, the third drive component 36 is actuated, the clamping openings 374 are opened, and then the two second drive components 35 drive the two clamping components 37 to approach each other. At the same time, the first drive component 34 drives the second mounting plate 33 to rise, so that the air bag 11 is separated from the clamping openings 374. After that, the pallet positioning device 2 no longer positions the pallet 10, and the transport device 1 continues to start and run. It can be imagined that after the air bag 11 is clamped, the two clamping components 37 move away from each other from the middle of the air bag 11 to the outside, and the two clamping openings 374 exert a pulling force on the air bag 11 between the two clamping openings 374, so that the air bag 11 passing through the clamping openings 374 will not be wrinkled or bent, and the straightening effect is better.

[0061] Specifically, in order to realize the straightening of the air bag 11 by the two clamping assemblies 37, in this embodiment, Figure 7 As shown, the clamping assembly 37 includes a third mounting plate 371 and a fourth mounting plate 372 that are spaced apart along the second direction, wherein a side wall adjacent to the third mounting plate 371 and the fourth mounting plate 372 is provided with a plurality of clamping plates 373, the plurality of clamping plates 373 are distributed along the first direction, the plurality of clamping plates 373 on the third mounting plate 371 and the plurality of clamping plates 373 on the fourth mounting plate 372 are staggered to form a plurality of clamping openings 374, that is, the first clamping plate 373 of the third mounting plate 371 and the second clamping plate 373 of the fourth mounting plate 372 form a first clamping opening 374, and the third mounting plate 371 and the fourth mounting plate 372 form a first clamping opening 374. The second clamping plate 373 of the plate 371 and the second clamping plate 373 of the fourth mounting plate 372 form a second clamping opening 374, and so on, a plurality of clamping openings 374 are formed along the first direction to clamp the plurality of air bags 11 distributed along the first direction on the tray 10; correspondingly, the upper end of the third mounting plate 371 is slidably connected to the fourth mounting plate 372 along the first direction, and the third driving assembly 36 includes a third linear driving device 361 and a fourth linear driving device 362 installed at the output end of the second driving assembly 35, and the output end of the third linear driving device 361 is connected to the third mounting plate 371 The third mounting plate 371 is connected to the output end of the second driving assembly 35, and the third mounting plate 371 is slidably disposed at the output end of the second driving assembly 35, so that the third mounting plate 371 moves along the first direction. The output end of the fourth linear driving device 362 is connected to the fourth mounting plate 372, and the fourth mounting plate 372 is slidably disposed at the output end of the second driving assembly 35, so that the fourth mounting plate 372 moves along the first direction. The third linear driving device 361 and the fourth linear driving device 362 respectively drive the third mounting plate 371 and the fourth mounting plate 372, so that the two mounting plates move in opposite directions, so that the clamping plate 371 of the third mounting plate 371 is 73 and the clamping plate 373 on the mounting plate move closer to or farther away from each other, thereby opening or closing the clamping opening 374 to achieve the closing and opening of the clamping opening 374 and clamp and release the airbag 11. The two clamping plates 373 move closer to or farther away from each other, which can more quickly achieve the clamping and release of the airbag 11. Moreover, the two clamping plates 373 move closer to each other to achieve the closing of the clamping opening 374, making the alignment requirement between the clamping opening 374 and the airbag 11 more relaxed. It is only necessary for the airbag 11 to be located in the center of the clamping opening 374, and the airbag 11 can enter the clamping opening 374 more smoothly.

[0062] Specifically, Figure 5-6As shown, the second driving assembly 35 includes a second linear driving device 351, a first connecting plate, a second connecting plate and a third connecting plate, wherein the first connecting plate, the second connecting plate and the third connecting plate are distributed along the first direction. Specifically, the second linear driving device 351 is arranged on the upper end surface of the second mounting plate 33, and the upper end surface of the second mounting plate 33 is provided with a through hole.

The lower ends of the first connecting plate and the third connecting plate are correspondingly slidingly connected to the two end portions of the third mounting plate 371 along the first direction, so that the upper ends are slidingly arranged on the second mounting plate 33 along the second direction, so that under the drive of the second linear driving device 351, the clamping assembly 37 can move along the second direction, and the first connecting plate and the second connecting plate slide along the second direction, so that the two clamping assemblies 37 are close to or away from each other in the second direction.

[0063] Moreover, the upper end of the first connecting plate is slidably connected to the fourth mounting plate 372 along the first direction, the upper end of the third connecting plate is slidably connected to the fourth mounting plate 372 along the first direction, and the lower ends of the first connecting plate, the second connecting plate and the third connecting plate are all slidably connected to the third mounting plate 371 along the first direction, and the third linear drive device 361 is installed on the second connecting plate, and the fourth linear drive device 362 is installed on the third connecting plate, so that the third linear drive device 361 drives the third mounting plate 371 to move in the first direction, and the fourth linear drive device 362 drives the fourth mounting plate 372 to move in the first direction. In this embodiment, the first connecting plate, the second connecting plate and the third connecting plate can all serve as the output end of the second drive assembly 35.

[0064] Specifically, in this embodiment, if Figure 5-6As shown, the first connecting plate includes a first horizontal plate 353 and a first vertical plate 352, the lower end of the first vertical plate 352 is slidably connected to the third mounting plate 371, and the upper end is connected to the first horizontal plate 353, the first horizontal plate 353 is slidably connected to the upper end surface of the second mounting plate 33 along the second direction, and a fourth horizontal plate 375 is provided at the upper end of the fourth mounting plate 372, the fourth horizontal plate 375 is located below the first horizontal plate 353, and the two are slidably connected along the first direction; the second connecting plate includes a second horizontal plate 355 and a second vertical plate 354, the lower end of the second vertical plate 354 is slidably connected to the third mounting plate 371, and the upper end is connected to the second horizontal plate 355, and the second The horizontal plate 355 is connected to the driving end of the second linear drive device 351, and the third linear drive device 361 is installed on the second vertical plate 354; the third connecting plate includes a third horizontal plate 357 and a third vertical plate 356, the lower end of the third vertical plate 356 is slidably connected to the third mounting plate 371, and the upper end is connected to the third horizontal plate 357, the third horizontal plate 357 is slidably connected to the upper end surface of the second mounting plate 33 along the second direction, the third linear drive device 361 is installed on the third horizontal plate 357, and the upper end of the fourth mounting plate 372 is provided with a fifth horizontal plate 376, the fifth horizontal plate 376 is located below the third horizontal plate 357, and the two are slidably connected along the first direction.

[0065] Specifically, the above-mentioned sliding connection is realized by a combination of sliders and slide rails. For example, the outer wall of the third mounting plate 371 is installed with a first slide rail 4 along the first direction, and correspondingly, the lower inner wall of the first vertical plate 352, the second vertical plate 354 and the third vertical plate 356 is installed with a first slider 7, and the first slider 7 is installed on the first slide rail 4, so that the third mounting plate 371 moves along the first direction; for example, the lower end surface of the first horizontal plate 353 and the third horizontal plate 357 is installed with a second slide rail 5, and the upper end surface of the fourth horizontal plate 375 and the fifth horizontal plate 376 is installed with a second slider 8, and the second slide rail 5 is connected with the second slider 8 to realize that both the fourth mounting plate 372 and the third mounting plate 371 can move along the first direction; for example, the third slider 9 is provided on the lower end surface of the first horizontal plate 353 and the third horizontal plate 357, and two third slide rails 6 are provided on the second mounting plate 33 along the second direction, and the two third slide rails 6 are distributed at both ends along the first direction.

Specifically, the second linear driving device 351, the third linear driving device 361 and the fourth linear driving device 362 are all rodless cylinders.

[0066] Specifically, the edge of the lower end of the clamping plate 373 is chamfered to provide a larger space for the air bag 11 to initially enter the clamping opening 374 , making it easier for the air bag 11 to enter the clamping opening 374 .

[0067] Of course, in another embodiment, the difference from the present embodiment lies in that: the lower ends of the first vertical plate 352, the second vertical plate 354 and the third vertical plate 356 are fixedly connected to the third mounting plate 371, and the third drive assembly 36 does not include the third linear drive device 361, so that under the drive of the fourth linear drive device 362, only the fourth mounting plate 372 moves along the first direction, so that the clamping mouth 374 opens and closes; of course, in another embodiment, the difference from the present embodiment lies in that: the first horizontal plate 353 and the third horizontal plate 357 are fixedly connected to the fourth horizontal plate 375 and the fifth horizontal plate 376, respectively, and the third drive assembly 36 does not include the fourth linear drive device 362, so that under the drive of the third linear drive device 361, only the third mounting plate 371 moves along the first direction, so that the clamping mouth 374 opens and closes.

The lower end of the guide shaft 342 is installed on a shaft seat provided on the second mounting plate 33, and the upper end passes through the linear bearing 344 and is located above it. Specifically, there are four guide shafts 342, which are evenly distributed on the outer peripheral side of the first linear drive device 341, and the upper ends of the four guide shafts 342 are all connected to the fixed plate 343 to increase the connection strength.

[0069] Specifically, the pallet positioning device 2 includes a positioning component and a blocking component, wherein the blocking component is used to stop the pallet 10 transported on the transport device 1. In the present embodiment, the blocking component includes a fifth drive device 21 and a baffle 22. The fifth drive device 21 may be a cylinder fixed on the cross bar of the mounting frame under the roller. The baffle 22 is vertically arranged upward and is located between the two rollers and is connected to the output end of the fifth drive device 21.
