Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery production, and in particular to a soft-pack lithium battery packaging support robot. Background Art

[0002] Soft-pack lithium batteries are simply liquid lithium-ion batteries covered with a polymer shell and structurally packaged with aluminum-plastic film. In the event of a safety hazard, the soft-pack lithium battery will at most bulge and crack. The weight of a soft-pack lithium battery is 40% lighter than a steel-shell lithium battery of the same capacity and 20% lighter than an aluminum-shell battery. The capacity of a soft-pack lithium battery is 10% to 15% higher than a steel-shell battery of the same specification and size, and 5% to 10% higher than an aluminum-shell battery. The internal resistance of a soft-pack lithium battery is smaller than that of a lithium battery. At present, the internal resistance of domestic soft-pack lithium battery cells can be as low as 35mΩ or less, which greatly reduces the battery's self-consumption.

[0003] In the prior art, for example, Chinese patent number CN109256591B is a soft-pack lithium battery packaging support robot, comprising a supporting base plate, a clamping device and a positioning device, wherein the clamping device is installed on the top of the left end of the supporting base plate, and the positioning device is installed on the top of the right end of the supporting base plate; the clamping device comprises a clamping top plate, a clamping pillar, a clamping push rod, a first clamping mechanism, a clamping connecting plate, a clamping pillar, a correction mechanism and a supporting mechanism; the first clamping mechanism comprises a clamping support plate, a clamping block, a block push rod, a clamping vertical plate, a movable clamping plate and a clamping plate push rod. The invention can solve the problems existing in the secondary packaging of soft-pack lithium batteries, such as the difficulty in adjusting the position of the soft-pack battery, the inability to fully lock the soft-pack battery according to its structure, and the inability to stretch and tighten the aluminum-plastic film at one end of the soft-pack battery.

[0004] Although the above scheme has the advantages as mentioned above, the disadvantage of the above scheme is that although it can firmly fix the soft-pack lithium battery and straighten and tighten the aluminum-plastic film on the right end of the soft-pack battery, it has the advantages of easy position adjustment of the soft-pack battery, full-range locking of the soft-pack battery according to its structure, and the ability to stretch and tighten the aluminum-plastic film at one end of the soft-pack battery. However, it can only meet the function of position adjustment and fixation of the soft-pack lithium battery during the second sealing process, and cannot meet the requirement that the side of the soft-pack lithium battery needs to be packaged when the soft-pack lithium battery is top-sealed, and cannot adjust the orientation of the soft-pack lithium battery, resulting in low applicability of the device. After the second sealing of the soft-pack lithium battery is completed, in order to ensure that the width of the battery cell does not exceed the standard, the air bag of the soft-pack lithium battery needs to be trimmed. The manual processing method is time-consuming and labor-intensive, resulting in low efficiency in the production of soft-pack lithium batteries. Summary of the Invention

A guide groove 306 is opened at the top of the U-shaped frame 305, and the outer surface of the threaded block 309 is movably embedded in the inside of the guide groove 306. A motor 308 is fixedly installed on one side of the U-shaped frame 305, and the output end of the motor 308 is fixedly installed on the other end of the screw rod 307. The outer surfaces of the two connecting members 302 are both movably sleeved with springs 304, one end of the two springs 304 is respectively fixedly mounted on the opposite side of the two fixing bars 301, and the other end of the two springs 304 is respectively fixedly mounted on the opposite side of the two blocks 303.

[0034] In one embodiment, the connector 302 is fixedly mounted on one side of the fixing bar 301. The connector 302 uses a telescopic rod. After the second seal of the soft-pack lithium battery on the support plate 401 is completed, the block 303 is manually pulled to one side to extend the connector 302 and stretch the spring 304, so that the edge of the air bag of the soft-pack lithium battery is disposed between the U-shaped block 1 311 and the U-shaped block 2 313. Then, the screw 314 is manually rotated to cooperate with the thread of the U-shaped block 2 313 and guided by the guide rod 1 312. The U-shaped block 2 313 can be moved along the thread direction of the screw 314 toward the outer surface of the U-shaped block 1 311 to clamp the air bag. Note that the trimming knife 310 needs to be moved to one of the sets of U-shaped The second block 313 is in the groove of the U-shaped block 1 311, and then the block 303 is loosened, so that the air bag is pulled under the restoring force of the spring 304, so that the air bag is in a taut state. At this time, the motor 2 308 is started by the controller, so that its output shaft drives the screw rod 307 to rotate, and then under the action of the threaded cooperation between the screw rod 307 and the threaded block 309, and under the cooperation of the guide groove 306 on the limiting guide of the threaded block 309, the threaded block 309 can drive the trimming knife 310 to move to one side along the outer surface of the screw rod 307, and the trimming knife 310 is used to trim the air bag of the soft-pack lithium battery. In this way, there is no need to manually use a trimming tool to trim the air bag of the soft-pack lithium battery. This method saves time and effort, thereby improving the efficiency of soft-pack lithium battery production.

[0035] In another embodiment, the connecting piece 302 is movably embedded in one side of the fixing bar 301. The connecting piece 302 is a round rod. After the soft-pack lithium battery on the support plate 401 is sealed, the block 303 is manually pulled to one side to slide the connecting piece 302 to the side, so that the spring 304 is stretched, so that the edge of the air bag of the soft-pack lithium battery is disposed between the U-shaped block 1 311 and the U-shaped block 2 313. Then, the screw 314 is manually rotated to cooperate with the thread of the U-shaped block 2 313, and under the guidance of the guide rod 1 312, the U-shaped block 2 313 can be moved along the thread direction of the screw 314 toward the outer surface of the U-shaped block 1 311 to clamp the air bag. Note that the trimming knife 310 needs to be moved to one of the groups of U The second U-shaped block 313 and the first U-shaped block 311 are then released, and the block 303 is then released, so that the air bag is pulled under the restoring force of the spring 304, so that the air bag is in a taut state. At this time, the motor 2 308 is started by the controller, so that its output shaft drives the screw rod 307 to rotate, and then under the action of the threaded cooperation between the screw rod 307 and the threaded block 309, and under the cooperation of the guide groove 306 on the limiting guide of the threaded block 309, the threaded block 309 can drive the trimming knife 310 to move to one side along the outer surface of the screw rod 307, and the trimming knife 310 is used to trim the air bag of the soft-pack lithium battery. In this way, there is no need to manually use a trimming tool to trim the air bag of the soft-pack lithium battery. This method saves time and labor, thereby improving the efficiency of soft-pack lithium battery production.

[0036] Working principle: When in use, first place the soft-pack lithium battery to be encapsulated on the elastic sponge plate 408, support the soft-pack lithium battery through the support plate 401, and then control the telescopic part 404 to start through the controller to shrink, driving the L-shaped slide plate 403 to slide along the outer surface of the guide rod 2 407 toward the soft-pack lithium battery, and simultaneously drive the push plate 405 and the elastic sponge plate 2 409 to move toward the soft-pack lithium battery, pushing the soft-pack lithium battery to move toward the center of the support plate 401, positioning the soft-pack lithium battery so that the soft-pack lithium battery is in the center position, and with the cooperation of the elastic sponge plate 2 409, damage to the soft-pack lithium battery can be avoided, so that the positioning of the soft-pack lithium battery can be easily completed, thereby facilitating subsequent positioning of the soft-pack lithium battery. The packaging of the battery and the trimming of the air bag, when the centering positioning of the soft-pack lithium battery is completed, the controller controls the telescopic member 1 404 to stretch, which can make the push plate 405 and the elastic sponge plate 2 409 move in the opposite direction, so that the push plate 405 and the elastic sponge plate 2 409 gradually move away from the soft-pack lithium battery, and then the controller controls the telescopic member 2 502 to start and stretch it, so that it drives the pressing plate 503 and the elastic sponge plate 3 504 to move downward, and squeezes the soft-pack lithium battery above the support plate 401 to a certain extent, so that the soft-pack lithium battery is fixed, and with the cooperation of the elastic sponge plate 1 408 and the elastic sponge plate 3 504, damage to the soft-pack lithium battery can be avoided, and the guide rod 3 505 is simultaneously made to slide downward, and the packaging equipment can be used for the packaging of the battery. The soft-pack lithium battery is top-sealed. When the top-sealing is completed and the soft-pack lithium battery needs to be side-sealed, the controller controls the motor 1 202 to start, so that its output shaft drives the rotating shaft 203 to rotate, and synchronously drives the gear 1 204 to rotate. Then, under the action of the meshing of the gear 1 204 and the gear 2 205, the rotating rod 1 102 can be driven to rotate. Then, under the interaction of one of the pulleys 1 103, the belt strip 1 104 and the pulley 2 105, the rotating rod 2 106 can be driven to rotate, and the pressing mechanism 5 can be driven to rotate. Synchronously, under the interaction of the other pulley 1 103, the belt strip 2 107 and the pulley 3 109, the rotating rod 3 111 can be driven to rotate, and the supporting positioning mechanism 4 can be driven to rotate, so that ... The soft-pack lithium battery between the pressing plates 503 is rotated to change the orientation of the soft-pack lithium battery, so that one of the side edges of the soft-pack lithium battery moves to the position of the trimming mechanism 3. This can not only meet the function of adjusting and fixing the position of the soft-pack lithium battery during the second sealing process, but also meet the need for the side edges of the soft-pack lithium battery to be packaged when the soft-pack lithium battery is top-sealed, thereby improving the applicability of this device. After the soft-pack lithium battery on the support plate 401 completes the second sealing, the block 303 is manually pulled to one side to extend the connector 302 and stretch the spring 304, so that the edge of the air bag of the soft-pack lithium battery is disposed between the U-shaped block 1 311 and the U-shaped block 2 313, and then the screw 314 is manually rotated to cooperate with the thread of the U-shaped block 2 313.Under the guidance of the guide rod 1 312, the U-shaped block 2 313 can be moved along the thread direction of the screw 314 toward the outer surface of the U-shaped block 1 311 to clamp the air bag. Note that the trimming knife 310 needs to be moved into the groove of one set of U-shaped blocks 2 313 and U-shaped block 1 311. Then, the block 303 is released, so that the air bag is pulled under the reset force of the spring 304, so that the air bag is in a taut state. At this time, the controller controls the motor 2 308 to start and output The shaft drives the screw rod 307 to rotate. Then, under the action of the threaded cooperation between the screw rod 307 and the threaded block 309, and with the cooperation of the guide groove 306 to limit and guide the threaded block 309, the threaded block 309 can drive the trimming knife 310 to move sideways along the outer surface of the screw rod 307. The trimming knife 310 trims the air bag of the soft-pack lithium battery. This eliminates the need for manual trimming tools to trim the air bag of the soft-pack lithium battery. This method saves time and labor, thereby improving the efficiency of soft-pack lithium battery production.
