Description

Technical Field

[0002] Lithium batteries are widely used in electric vehicles. When producing lithium batteries, multiple tab foils need to be welded together using ultrasound. Since the tab foil is thin, in order to prevent the tab foil from being damaged and broken during welding, a protective sheet needs to be stacked with the tab foil. During welding, the energy, pressure, amplitude and other parameters of the tab foil will be more adaptable, thereby improving the welding effect and welding quality.

[0003] The existing protection sheet feeding device feeds the protection sheet through the material taking component, and the material taking component uses vacuum negative pressure to suck the protection sheet, and then transports the protection sheet to the tab welding station. The protection sheets are usually stacked on the storage mechanism, and the adjacent protection sheets are tightly attached. Since the protection sheets are light and thin, when the material taking component uses negative pressure to suck the protection sheets, multiple protection sheets of the stacked protection sheets will be sucked at the same time, resulting in sticking, sheet carrying and other phenomena, resulting in multiple protection sheets being transported to the tab welding station at the same time, affecting the welding quality.

DETAILED DESCRIPTION

[0028] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] A preferred embodiment of a feeding device of the present invention is as follows Figures 1 to 7 As shown, the feeding device is used to feed the protective sheet 400 during the tab welding operation, and the feeding device has a first direction X, a second direction Y and a third direction Z that intersect each other. In this embodiment, the first direction X, the second direction Y and the third direction Z are perpendicular to each other, wherein the first direction X is the left-right direction of the feeding device, the second direction Y is the front-back direction of the feeding device, and the third direction Z is the height direction of the feeding device.

[0030] The feeding device includes a feeding mechanism 100 and a detection mechanism 200. The feeding mechanism 100 is used to absorb and transfer the protection sheet 400 and separate the protection sheet 400 by vibration. The detection mechanism 200 is used to absorb and separate the protection sheet 400 that may still be sticky after vibration separation and automatically recover the protection sheet 400.

[0031] The material picking mechanism 100 includes a base 110, a suction cup 120, a vibrating member 130, a first driving member 140 and a second driving member 150. The first driving member 140 is connected to the base 110 in a transmission connection, the second fixing member is fixedly connected to the base 110, and the second driving member 150 is connected to the suction cup 120 in a transmission connection. The first driving member 140 can drive the base 110 to move along a first direction X, and the second driving member 150 can drive the suction cup 120 to reciprocate along a third direction Z.

[0032] In this embodiment, the first driving member 140 is a transverse movement module, and the first driving member 140 includes a transverse movement motor, a slide rail and a screw assembly, the screw assembly is transmission-connected between the transverse movement motor and the base 110, the slide rail extends along the first direction X, and the base 110 is slidably assembled on the slide rail along the first direction X. The transverse movement motor changes the rotation direction, which can change the moving direction of the base 110, so that the base 110 reciprocates along the first direction X. In this embodiment, the second driving member 150 is specifically a cylinder, which can drive the suction cup 120 to reciprocate along the third direction Z by changing the direction of air inlet and outlet.

[0033] The suction cup 120 can be connected to an external vacuum device. When the suction cup 120 moves along the third direction Z, the negative pressure can be used to fix the protective sheet 400. When the suction cup 120 moves along the first direction X, the adsorbed protective sheet 400 can be transferred to the position of the detection mechanism 200 to calibrate and detect the number of protective sheets 400. The suction cup 120 can also be moved to the tab welding station to assist in the tab welding operation.

[0034] The vibrating member 130 is fixedly connected to the suction cup 120, and the vibrating member 130 can drive the suction cup 120 to vibrate along the second direction Y. After the suction cup 120 absorbs the stacked protection sheets 400 by vacuum, some of the protection sheets 400 will stick to the tape sheet. The vibrating member 130 drives the suction cup 120 to vibrate along the second direction Y, and the excess protection sheets 400 can be shaken off by the vibration action, so that the suction cup 120 only absorbs one or two protection sheets 400.

[0035] The vacuum degree of the suction cup 120 is P1. In the present embodiment, P1 is specifically -90 KPa. Under this vacuum degree, the suction cup 120 can adsorb and fix the protective sheet 400 on the bottom of the suction cup 120. During the vibration of the vibrating member 130, at least one protective sheet 400 will not fall off, and the protective sheet 400 is stably adsorbed during the transfer along the first direction X and the second direction Y.

[0036] The detection mechanism 200 includes an adsorption block 210, a waste discharge groove 220 and a third driving member 230. The adsorption block 210 is used to adsorb and fix the protective sheet 400. The adsorption block 210 and the suction cup 120 are spaced apart along the first direction X. When the first driving member 140 drives the suction cup 120 to move along the first direction X, the suction cup 120 can move to the adsorption block 210, so that when two protective sheets 400 are stuck together, the adsorption block 210 can adsorb one of the two protective sheets 400 closer to the adsorption block 210.

[0037] The third driving member 230 is in transmission connection with the adsorption block 210, and the third driving member 230 can drive the adsorption block 210 to flip over to the waste discharge trough 220. When the vacuum degree of the adsorption block 210 is zero, the adsorption force of the adsorption block 210 is zero. At this time, the protective sheet 400 on the adsorption block 210 can fall into the waste discharge trough 220 under the action of gravity, and the separated protective sheet 400 can be recycled to save materials. When the second driving member 150 drives the suction cup 120 to move along the third direction Z, the suction cup 120 can fit with the adsorption block 210. Along the third direction Z, the suction cup 120 and the adsorption block 210 are respectively located on both sides of the stacked protective sheet 400. In the present embodiment, the third driving member 230 is specifically a flip motor, and the flip shaft of the flip motor is fixedly connected to the adsorption block 210 to drive the adsorption block 210 to rotate.

[0038] The vacuum degree of the adsorption block 210 is P2, which satisfies: P1>P2. In this embodiment, P2 is specifically -30Kpa. Under this vacuum degree, the vacuum degree of the suction cup 120 is much greater than the vacuum degree of the adsorption block 210. After the second driving member 150 drives the suction cup 120 to fit with the adsorption block 210, if only one protective sheet 400 is adsorbed on the suction cup 120 at this time, the pressure difference between the suction cup 120 and the adsorption block 210 is greater than the gravity of the protective sheet 400, and the protective sheet 400 is still adsorbed on the suction cup 120, and can be moved with the suction cup 120 to the next process of the pole ear welding station; if two protective sheets 400 are adsorbed on the suction cup 120 at this time, the bonding force between the two protective sheets 400 is not large, and the vacuum adsorption force of the adsorption block 210 is greater than the bonding force, when the second driving member 150 drives the suction cup 120 to move away from the adsorption block 210 along the third direction Z, the two sticky protective sheets 400 are separated, and the suction cup 120 can adsorb a single protective sheet 400 and move to the pole ear welding station.

[0039] The first driving member 140 and the second driving member 150 of the material taking mechanism 100 of the feeding device can respectively drive the suction cup 120 to move along the first direction X and the third direction Z. When the suction cup 120 moves along the third direction Z, the negative pressure can be used to absorb the protective sheet 400. Then the vibrating member 130 vibrates the suction cup 120 along the second direction Y to vibrate and separate the sticky protective sheet 400, thereby reducing the number of sticky protective sheets 400. Then the first driving member 140 can drive the suction cup 120 to move along the first direction X to the adsorption block 210. Then the suction cup 120 moves along the third direction Z to fit with the adsorption block 210. Since the vacuum degree P1 of the suction cup 120 is greater than the vacuum degree P2 of the adsorption block 210, if the protective sheet 400 is not sticky at this time, , a single protective sheet 400 is still adsorbed on the suction cup 120; if there are two protective sheets 400 adhered to the suction cup 120 at this time, the bonding force between the two protective sheets 400 will not be very large, the adsorption force of the adsorption block 210 is greater than the bonding force, the adsorption block 210 can separate the two protective sheets 400, the suction cup 120 can adsorb a single protective sheet 400 and move it to the pole ear welding station, the third driving member 230 can flip the adsorption block 210 to the waste discharge trough 220, and the protective sheet 400 falls into the waste discharge trough 220 under the action of gravity, and the separated protective sheet 400 is recycled, thereby avoiding the sticking and carrying phenomenon of the protective sheet 400, ensuring the welding quality, and the separated protective sheet 400 can also be reused to save materials.

[0040] In some embodiments, the detection mechanism 200 also includes a vacuum head 240 and a fourth driving member 260 that is transmission-connected to the vacuum head 240, and the fourth driving member 260 can drive the vacuum head 240 to connect or disconnect with the adsorption block 210 along the third direction Z; the detection mechanism 200 also includes a fifth driving member 280 and a moving seat 270, the third driving member 230 is fixedly connected to the moving seat 270, the fifth driving member 280 is transmission-connected to the moving seat 270, the fifth driving member 280 can drive the moving seat 270 to reciprocate along the second direction Y, and the moving seat 270 can drive the adsorption block 210 to reciprocate between the vacuum head 240 and the waste discharge trough 220.

[0041] The vacuum head 240 is in transmission connection with the fourth driving member 260, and the fourth driving member 260 can drive the vacuum head 240 to move along the third direction Z. When the vacuum head 240 moves toward the adsorption block 210 along the third direction Z, it can be connected with the adsorption block 210, and a vacuum is generated in the adsorption block 210, so that the adsorption block 210 adsorbs the protective sheet 400 through the vacuum negative pressure; when the vacuum head 240 moves away from the adsorption block 210 along the third direction Z, it is disconnected from the adsorption block 210, and there is no negative pressure in the adsorption block 210 at this time. After the third driving member 230 drives the adsorption block 210 to move to the waste discharge tank 220, the protective sheet 400 can fall into the waste discharge tank 220 under the action of gravity.

[0042] The fourth driving member 260 is set to drive the vacuum head 240 to move to connect or disconnect the adsorption block 210. Adjusting the position of the vacuum head 240 can control whether there is a vacuum in the adsorption block 210, which simplifies the actions of the adsorption block 210 adsorbing, transferring and removing the protective sheet 400, and is easy to use.

[0043] The third driving member 230 is fixedly connected to the moving seat 270, and the fifth driving member 280 can drive the moving seat 270 to reciprocate along the second direction Y, thereby adjusting the positions of the third driving member 230 fixed on the moving seat 270 and the adsorption block 210 connected to the third driving member 230 in the second direction Y, so that the adsorption block 210 can reciprocate between the vacuum head 240 and the waste discharge tank 220. When the adsorption block 210 moves to the vacuum head 240 along the second direction Y, the vacuum head 240 is connected to the adsorption block 210 along the third direction Z, and the adsorption block 210 can pass through the protective sheet 400 on the vacuum suction cup 120; after the vacuum head 240 is disconnected from the adsorption block 210 along the third direction Z, the fifth driving member 280 drives the adsorption block 210 to move to the upper side of the waste discharge tank 220 along the second direction Y, and the third driving member 230 can drive the adsorption block 210 to flip and transfer the protective sheet 400 to the waste discharge tank 220. In this embodiment, the fifth driving member 280 is specifically a cylinder.

[0044] In some embodiments, the detection mechanism 200 also includes a detection clamp 290, the detection clamp 290 has a slide groove 291 and a perforation 292, the slide groove 291 extends along the third direction Z, the vacuum head 240 is slidably arranged on the slide groove 291 along the third direction Z, the perforation 292 penetrates the detection clamp 290 along the second direction Y, the perforation 292 is connected to the slide groove 291, and the adsorption block 210 can penetrate the perforation 292 along the second direction Y; the fourth driving member 260 is fixedly connected to the detection clamp 290, the waste discharge trough 220 is fixedly connected to the detection clamp 290, and the waste discharge trough 220 and the slide groove 291 are spaced apart along the second direction Y.

[0045] The vacuum head 240 is slidably arranged in the slide groove 291 along the third direction Z. The slide groove 291 can be used to guide the movement of the vacuum head 240, so that the vacuum head 240 can only move back and forth along the third direction Z, ensuring that the vacuum head 240 can accurately dock with the adsorption block 210 to generate a vacuum in the adsorption block 210. The detection clamp 290 is provided with a perforation 292 for the adsorption block 210 to pass through along the second direction Y. The second perforation 292 can be used to limit the movement path of the adsorption block 210, and when the vacuum head 240 is connected or disconnected with the adsorption block 210, the hole wall of the perforation 292 can be used to provide pressure to the adsorption block 210, ensuring that the position of the adsorption block 210 is stable during the connection or disconnection process between the vacuum head 240 and the adsorption block 210.

[0046] In some embodiments, the fourth driving member 260 includes a vacuum lifting motor 261 fixedly connected to the detection clamp 290 and a push rod 262 transmission-connected to the vacuum lifting motor 261, the push rod 262 extends along the third direction Z, and the end of the push rod 262 away from the vacuum lifting motor 261 is fixedly connected to the vacuum head 240.

[0047] The fourth driving member 260 is formed by a vacuum lifting motor 261 and a push rod 262. The vacuum lifting motor 261 drives the vacuum head 240 to move along the third direction Z through the push rod 262. The vacuum lifting motor 261 and the push rod 262 are commonly used direct-acting mechanisms, which can simplify the structure of the fourth driving member 260, and are simple to arrange and maintain, and have low costs.

[0048] In some embodiments, the adsorption block 210 is rotatably mounted on the movable seat 270 about the second direction Y, the waste discharge tank 220 and the adsorption block 210 are arranged opposite to each other along the third direction Z, and the third driving member 230 can drive the adsorption block 210 to rotate about the second direction Y.

[0049] The adsorption block 210 is assembled on the moving seat 270 to rotate around the second direction Y, and the third driving member 230 drives the adsorption block 210 to rotate around the second direction Y. The waste discharge tank 220 and the adsorption block 210 are arranged opposite to each other along the third direction Z. When the adsorption block 210 rotates 180 degrees, the vacuum suction hole on the adsorption block 210 is aligned with the waste discharge tank 220, and the protection sheet 400 can fall into the waste discharge tank 220 by itself under gravity, so that the protection sheet 400 is easy to recover.

[0050] In some embodiments, the vibrating member 130 includes a first vibrating cylinder 131 and a second vibrating cylinder 132 . The first vibrating cylinder 131 and the second vibrating cylinder 132 are spaced apart along the first direction X. The first vibrating cylinder 131 and the second vibrating cylinder 132 are disposed on both sides of the suction cup 120 .

[0051] The vibrating member 130 is formed by a first vibrating cylinder 131 and a second vibrating cylinder 132 which are symmetrically arranged. After the suction cup 120 adsorbs the protective sheet 400, the first vibrating cylinder 131 and the second vibrating cylinder 132 can work alternately to vibrate the two sides of the suction cup 120 respectively, thereby increasing the vibration amplitude of the suction cup 120, causing the multiple sticky protective sheets 400 to fall off due to the vibration, thereby improving the effect of the vibrating member 130 vibrating to separate the protective sheets 400.

[0052] In some embodiments, the suction cup 120 includes an assembly seat 121 and a suction nozzle 122 fixedly connected to the assembly seat 121, the second driving member 150 is fixedly connected to the assembly seat 121, the vibration member 130 is fixedly connected to the fixed seat, and along the second direction Y, the vibration member 130 and the suction nozzle 122 are located on both sides of the assembly seat 121.

[0053] The suction cup 120 is formed by the assembly seat 121 and the suction nozzle 122. After the second driving member 150 is fixedly connected to the assembly seat 121, it can drive the assembly seat 121 to reciprocate along the third direction Z, thereby driving the suction nozzle 122 to move synchronously, and using the suction nozzle 122 to suck the protective sheet 400. The vibration member 130 and the suction nozzle 122 are located on both sides of the assembly seat 121 along the second direction Y, and the assembly space on both sides of the assembly seat 121 can be reasonably used. The vibration member 130 can drive the suction nozzle 122 to vibrate by vibrating the assembly seat 121.

[0054] In some embodiments, the loading device also includes a storage mechanism 300, the storage mechanism 300 includes a material storage clamp 310, a push block 320 and a sixth driving member 330, the material storage clamp 310 has a storage cavity 311, the push block 320 is arranged in the storage cavity 311, the sixth driving member 330 is transmission-connected with the push block 320, and the sixth driving member 330 can push the push block 320 to slide along the third direction Z in the storage cavity 311.

[0055] The storage mechanism 300 is used to store the protection sheets 400, and multiple protection sheets 400 can be stacked and stored in the storage cavity 311 of the storage clip 310. The push block 320 is arranged in the storage cavity 311, and the sixth driving member 330 is in transmission connection with the push block 320 to drive the push block 320 to slide along the third direction Z. The push block 320 can change the height of the stacked protection sheets 400 in the process of moving along the third direction Z. After the suction cup 120 absorbs and transfers the protection sheets 400, the push block 320 can move upward, so that the top protection sheet 400 is always at the same height each time, which is convenient for the suction cup 120 to absorb.

[0056] In addition, after the suction cup 120 absorbs the protective sheet 400, the vibrating member 130 will vibrate the suction cup 120. At this time, the sixth driving member 330 can first drive the push block 320 to descend along the third direction Z to move away from the suction cup 120, so that a space is reserved between the protective sheet 400 on the suction cup 120 and the protective sheet 400 in the storage cavity 311. During vibration, the excess protective sheet 400 on the suction cup 120 can be vibrated off. In this embodiment, the specific structure of the sixth driving member 330 is the same as the specific structure of the fourth driving member 260.

[0057] In some embodiments, the material storage clamp 310 is further provided with a guide groove 312 extending along the third direction Z, and the push block 320 cooperates with the guide groove 312 to guide along the third direction Z.

[0058] A guide groove 312 is provided on the material storage clamp 310 , which guides the push block 320 to ensure that the push block 320 always moves along the third direction Z when moving in the storage cavity 311 , thereby preventing the push block 320 from deviating from the third direction Z and interfering with the inner wall of the material storage clamp 310 .

[0059] The working process of the present invention is as follows: when loading materials, the first driving member 140 drives the base 110 and the suction cup 120 thereon to move to the upper side of the material storage clamp 310 of the storage mechanism 300 along the first direction X, and the second driving member 150 drives the suction cup 120 to extend into the storage cavity 311 of the material storage clamp 310 along the third direction Z, and the suction nozzle 122 uses vacuum to absorb the protection sheet 400; the sixth driving member 330 drives the push block 320 to move downward along the third direction Z, so that the protection sheet 400 in the storage cavity 311 moves downward, and there is a gap between the protection sheet 400 in the storage cavity 311 and the protection sheet 400 on the suction nozzle 122, and the first The vibrating cylinder 131 and the second vibrating cylinder 132 vibrate the assembly seat 121 alternately along the second direction Y, and the assembly seat 121 drives the suction nozzle 122 to vibrate, so that the excess protective sheet 400 falls into the storage cavity 311 of the material storage clamp 310; after the vibration is completed, the first driving member 140 drives the suction cup 120 to move along the first direction X to the upper side of the detection clamp 290, at this time, the fifth driving member 280 drives the adsorption block 210 to pass through the through hole 292 along the second direction Y into the detection clamp 290, and the vacuum lifting motor 261 drives the push rod 262 to move along the third direction Z, driving the vacuum head 240 to connect with the adsorption block 210 along the third direction Z. The second driving member 150 drives the suction cup 120 to move downward along the third direction Z, and the suction nozzle 122 of the suction cup 120 fits with the adsorption block 210. Since the vacuum degree of the suction cup 120 is greater than the vacuum degree of the adsorption block 210, the adsorption force of the suction cup 120 on the protection sheet 400 is greater than the adsorption force of the adsorption block 210 on the protection sheet 400. At the same time, the adsorption force of the suction cup 120 on the protection sheet 400 is greater than the bonding force between the two adhered protection sheets 400. If the protection sheet 400 is not adhered at this time, a single protection sheet 400 is still adsorbed on the suction cup 120. If there are two protection sheets 400 adhered to the suction cup 120 at this time, the second driving member 150 drives the suction cup 120 to move downward along the third direction Z, and the suction nozzle 122 of the suction cup 120 fits with the adsorption block 210. Since the vacuum degree of the suction cup 120 is greater than the vacuum degree of the adsorption block 210, the adsorption force of the suction cup 120 on the protection sheet 400 is greater than the bonding force between the two adhered protection sheets 400. When the moving member 150 drives the suction cup 120 to move upward along the third direction Z, the adsorption block 210 can separate the two protection sheets 400, and the suction cup 120 can adsorb a single protection sheet 400 and move it to the tab welding station; the fourth driving member 260 drives the vacuum head 240 to move downward along the third direction Z, disconnecting the connection between the vacuum head 240 and the adsorption block 210, and the fifth driving member 280 drives the adsorption block 210 to move along the second direction Y to the upper side of the waste discharge trough 220, and the third driving member 230 can drive the adsorption block 210 to flip over and transfer the recovered protection sheet 400 to the waste discharge trough 220, thereby completing the recycling of the protection sheet 400.

[0060] The present invention also provides a preferred embodiment of a battery production line, including a loading device, the specific structure of the loading device is the same as the specific structure of the loading device in any of the above embodiments, and will not be repeated here.

[0061] In summary, the embodiments of the present invention provide a feeding device and a battery production line, wherein the first driving member and the second driving member of the material picking mechanism can respectively drive the suction cup to move along the first direction and the third direction, and the suction cup can use negative pressure to absorb the protective sheet when it moves along the third direction, and then the vibrating member vibrates the suction cup along the second direction to vibrate and separate the sticky protective sheet, thereby reducing the number of sticky protective sheets; then the first driving member can drive the suction cup to move along the first direction to the adsorption block, and then the suction cup moves along the third direction to fit with the adsorption block. Since the vacuum degree P1 of the suction cup is greater than the vacuum degree P2 of the adsorption block, if the vacuum degree P2 of the adsorption block is The protective sheet is not sticky, and a single protective sheet is still adsorbed on the suction cup; if there are two protective sheets stuck to the suction cup at this time, the bonding force between the two protective sheets will not be very large, the adsorption force of the adsorption block is greater than the bonding force, the adsorption block can separate the two protective sheets, the suction cup can adsorb a single protective sheet and move it to the pole ear welding station, the third driving member can move the adsorption block to the waste discharge trough, and the protective sheet falls into the waste discharge trough under the action of gravity, and the separated protective sheets are recycled, thereby avoiding the stickiness and carrying of the protective sheets, ensuring the welding quality, and the separated protective sheets can also be reused to save materials.

[0062] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
