Description

Technical Field

[0002] In today's era of vigorous development of new energy, lithium-ion batteries have become the core energy supply components of new energy electric vehicles due to their significant advantages such as high energy density, long cycle life, and low self-discharge rate. The demand in the market has shown explosive growth. With the continuous expansion of the production scale of 18650 lithium-ion batteries, the requirements for the efficiency and safety of its production process have become increasingly stringent. Among them, the transportation of lithium-ion battery finished products, as a key link in the production process, has a relatively important impact on the overall production efficiency and product quality.

[0003] After the production of lithium-ion batteries is completed, their internal electrolytes will undergo an in-situ polymerization reaction. This reaction can optimize the performance of lithium-ion batteries, but it is also accompanied by heat generation that cannot be ignored. Existing lithium-ion battery in-situ polymerization products are usually directly transported outward after processing. During the transportation process, there is a lack of active cooling structure for the lithium-ion battery products. It is difficult to effectively dissipate the continuous heat generated by the in-situ polymerization inside the lithium-ion battery products during transportation by relying solely on natural heat dissipation. As a result, during the subsequent transportation process, the temperature of the lithium-ion battery in-situ polymerization products may continue to rise, which is not only likely to affect other subsequent processing steps, but may even cause thermal runaway in severe cases, affecting production safety.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Embodiment: This embodiment provides a lithium-ion battery in-situ polymerization finished product conveying device, see Figure 1 - Figure 13 Specifically, it includes a first electric conveyor belt 1 which is arranged horizontally, a longitudinally arranged electric push rod 101 is installed on the front of the first electric conveyor belt 1, a straight tube 2 which is arranged directly behind the electric push rod 101 is installed behind the first electric conveyor belt 1, and a first spiral roller 201 and a second spiral roller 202 which are symmetrically arranged are rotatably installed at the lower position inside the straight tube 2, the spiral directions of the first spiral roller 201 and the second spiral roller 202 are opposite, and the first spiral roller 201 and the second spiral roller 202 rotate synchronously in opposite directions, a first gear 203 which is transmission-connected to the first spiral roller 201 is rotatably installed at the lower position inside the straight tube 2, a second gear 204 which meshes with the first gear 203 is fixedly installed on the second spiral roller 202, and a transmission rod 205 which is transmission-connected to the first spiral roller 201 is rotatably installed at the lower position outside the straight tube 2.

[0021] During the operation of the device, after the lithium-ion battery is processed and produced, the electrolyte in it is in-situ polymerized to form a lithium-ion battery finished product with higher quality. The in-situ polymerized lithium-ion battery finished products are arranged in sequence on the first electric conveyor belt 1 and conveyed to the right for the first-stage conveyance. The lithium-ion battery finished products are longitudinally placed flat on the first electric conveyor belt 1. When the lithium-ion battery finished products are conveyed to the position corresponding to the electric push rod 101, the electric push rod 101 is powered on and starts. The telescopic end of the electric push rod 101 moves backward quickly and then contracts and resets, pushing the longitudinally placed lithium-ion battery finished products on the first electric conveyor belt 1 onto the first spiral roller 201 and the second spiral roller 202 corresponding to the electric push rod 101, preparing for the second-stage conveyance.

[0022] When using the first spiral roller 201 in cooperation with the second spiral roller 202 for the second-stage conveyance, a motor is arranged on the outer side of the straight pipe 2. The drive shaft of the motor is in transmission connection with the transmission rod 205. By driving the transmission rod 205 to rotate by the motor, after the transmission rod 205 rotates, the rotational power is transmitted to the first spiral roller 201 through the transmission belt, driving the first spiral roller 201 to rotate. During the rotation of the first spiral roller 201, the rotational power is transmitted to the first gear 203 through another transmission belt, and then, by means of the meshing of the first gear 203 and the second gear 204 fixed on the second spiral roller 202, the rotational power is synchronously and reversely transmitted to the second spiral roller 202, so that the first spiral roller 201 and the second spiral roller 202 rotate synchronously and reversely. Since the spiral directions on the first spiral roller 201 and the second spiral roller 202 are opposite, during the rotation of the first spiral roller 201 and the second spiral roller 202, by means of the axial conveying force during the rotation of the first spiral roller 201 and the second spiral roller 202, and the friction force between the lithium-ion battery finished products mounted on the first spiral roller 201 and the second spiral roller 202 and them, the lithium-ion battery is driven to move backward stably and smoothly in the straight pipe 2.

[0023] In the specific implementation process, such as Figure 3 , Figure 9 and Figure 12As shown, symmetrically arranged air pipes 206 are fixedly installed on the outer end walls on the left and right sides of the straight pipe 2. A first nozzle 207 communicating with the inside of the air pipe 206 is fixedly inlaid on the inner end wall of the straight pipe 2. The first nozzle 207 is horizontally arranged inside the air pipe 206, and the port of the first nozzle 207 communicating with the inner end wall of the straight pipe 2 is inclined backward. When the device operates, during the process of the finished lithium-ion battery being secondarily conveyed by the cooperation of the first spiral roller 201 and the second spiral roller 202 inside the straight pipe 2, after the air flow enters the inside of the air pipe 206, it will be ejected through the first nozzle 207 and then act on the finished lithium-ion battery conveyed inside the straight pipe 2. Through the high-speed flow of the air flow, the efficiency of heat dissipation from the inside of the straight pipe 2 to the outside can be effectively improved, and the heat dissipation efficiency of the finished lithium-ion battery inside the straight pipe 2 can be accelerated, so that after the finished lithium-ion battery is processed, the heat generated by the in-situ polymerization reaction can be quickly dissipated, which can effectively avoid the heat accumulation in the conveying channel due to direct conveying after in-situ polymerization, affecting the production and conveying safety of the finished lithium-ion battery, and to a certain extent, improving the stability and safety during the conveying process of the in-situ polymerized finished lithium-ion battery.

[0024] At the same time, by setting the ports of many first nozzles 207 close to the center position inside the straight pipe 2 to be inclined backward, when the air flow is ejected through the first nozzles 207 inside the straight pipe 2, the ejected air flow can act on the finished lithium-ion battery inside the straight pipe 2 obliquely. With the help of the air flow push, the smoothness of the finished lithium-ion battery during the secondary conveying inside the straight pipe 2 can be further improved, which is beneficial to improving the conveying efficiency.

[0025] In the specific implementation process, as Figure 2 、 Figure 4 、 Figure 8 and Figure 12 shown, the front ends of the first spiral roller 201 and the second spiral roller 202 are set to be conical structures. The rear ends of the first spiral roller 201 and the second spiral roller 202 protrude outside the straight pipe 2, and the lengths of the first spiral roller 201 and the second spiral roller 202 protruding outside the rear end of the straight pipe 2 are greater than the length of a single finished lithium-ion battery. A circular plate 3 is arranged behind the straight pipe 2, and a rotating cylinder 301 is rotatably installed at the center position of the circular plate 3. Four circumferentially distributed connecting pipes 302 are fixedly communicated with the outer end wall of the rotating cylinder 301, and a suction cup 303 is sleeved outside the connecting pipe 302. A horizontally arranged second electric conveyor belt 4 is installed directly below the circular plate 3.

[0026] During the operation of the device, the finished lithium-ion battery products that have completed the second-stage transportation are adsorbed and grabbed by the suction cup 303. Driven by the rotary drum 301, after rotating 270° clockwise, they are lowered in a vertical posture onto the second electric conveyor belt 4 for the third-stage transportation. By setting the front ends of the first spiral roller 201 and the second spiral roller 202 as conical structures, it makes it smoother for the lithium-ion battery to be pushed by the electric push rod 101 between the tops of the first spiral roller 201 and the second spiral roller 202 on the first electric conveyor belt 1. By setting the rear ends of the first spiral roller 201 and the second spiral roller 202 to protrude outside the straight pipe 2, when the suction cup 303 grabs the finished lithium-ion battery product and rotates counterclockwise, there will be no obstruction above the finished lithium-ion battery product, which is beneficial to ensuring the smooth stability when the finished lithium-ion battery product is transferred from the second-stage transportation to the third-stage transportation.

[0027] In the specific implementation process, as Figure 2 、 Figure 4 and Figure 8 shown, the suction cup 303 located directly in front is behind the straight pipe 2. The suction cup 303 is slidably sleeved on the connecting pipe 302. A straight rod 304 parallel to the corresponding connecting pipe 302 is fixedly installed on the outer end wall of the rotary drum 301. The suction cup 303 is slidably connected to the corresponding straight rod 304. A tension spring 305 is movably sleeved on the outside of the connecting pipe 302, and one end of the tension spring 305 is fixedly connected to the outer end wall of the rotary drum 301, and the other end of the tension spring 305 is fixedly connected to the suction cup 303. An air vent hole 306 located inside the suction cup 303 is opened on the outer end wall of the connecting pipe 302. A ring plate 307 sleeved on the outside of the numerous suction cups 303 is fixedly installed on the circular plate 3, and the shortest distance between the inner end wall of the ring plate 307 and the corresponding suction cup 303 is equal to the length of a single finished lithium-ion battery product. An inlet 308 located behind the straight pipe 2 is opened on the ring plate 307, and an outlet 309 located directly above the second electric conveyor belt 4 is opened on the ring plate 307.

[0028] During the operation of the device, after the ends of the first spiral roller 201 and the second spiral roller 202 of the finished lithium-ion battery conveyor belt, their rear ends just fit with a suction cup 303 directly in front. There is an air flow suction in the rotating cylinder 301, and the outside air enters the connecting pipe 302 through the suction cup 303 and then enters the rotating cylinder 301. With the negative pressure adsorption formed by the air flow suction, the finished lithium-ion batteries mounted at the ends of the first spiral roller 201 and the second spiral roller 202 are firmly adsorbed and connected by the suction cup 303 directly in front. Then, the rotating cylinder 301 drives the suction cup 303 and the finished lithium-ion batteries adsorbed on the suction cup 303 to rotate clockwise by 90° each time. Every time it rotates 90°, a suction cup 303 will switch to the direct front to adsorb and grab the continuously conveyed finished lithium-ion batteries mounted at the ends of the first spiral roller 201 and the second spiral roller 202. After the suction cup 303 that was originally in the direct front holds the finished lithium-ion battery and rotates 270°, it will move to the position directly below.

[0029] During the rotation of the suction cup 303 carrying the finished lithium-ion battery, since a surrounding ring plate 307 is fixedly installed on the outside of the rotating cylinder 301, and the shortest distance between the suction cup 303 and the inner end wall of the ring plate 307 is the same as the length of a single finished lithium-ion battery. With the stop of the ring plate 307, the ring plate 307 will not move relative to the connecting pipe 302 due to the weight of the finished lithium-ion battery. When the suction cup 303 carrying the finished lithium-ion battery moves to the lowest position, due to the existence of the outlet 309, the bottom of the finished lithium-ion battery loses support at this time. Under the action of gravity, the finished lithium-ion battery drives the suction cup 303 to drop, and the suction cup 303 slides relative to the connecting pipe 302, so that the air leakage holes 306 on the connecting pipe 302 that were originally inside the suction cup 303 are exposed. As a result, the negative pressure adsorption formed by the air flow suction inside the suction cup 303 is released, and the suction cup 303 releases the adsorption connection with the finished lithium-ion battery. Thus, after the finished lithium-ion battery is transferred above the second electric conveyor belt 4, it will automatically fall, converting the flat state of the finished lithium-ion battery conveyed in the second section to an upright state, which is conducive to conveniently and efficiently automatically adjusting the placement state of the finished lithium-ion battery during the conveying process. After the finished lithium-ion battery is separated from the suction cup 303, the suction cup 303 loses the downward force provided by the finished lithium-ion battery. Under the elastic pull of the tension spring 305, the suction cup 303 automatically resets relative to the connecting pipe 302, so that the air leakage holes 306 are retracted into the suction cup 303 again, and the suction cup 303 regains the negative pressure adsorption formed by the air flow suction. After rotating to the direct front, it can continue to perform the adsorption connection operation on the subsequent finished lithium-ion batteries, with cyclic operation, which is convenient and efficient.

[0030] In the specific implementation process, such as Figure 4 、 Figure 8 and Figure 13As shown in the figure, clamping rods 310 symmetrically arranged on both sides of the suction cup 303 are fixedly installed on the outer end wall of the rotary drum 301, and the width of the clamping rods 310 is less than the distance between the first spiral roller 201 and the second spiral roller 202. One end of the clamping rod 310 close to the ring plate 307 is arranged as an outwardly inclined structure. A plurality of uniformly distributed rollers 311 are rotatably installed on the lower end wall at the rear of the ring plate 307. During the operation of the device, by installing the clamping rods 310 on both sides of the suction cup 303, after the finished lithium-ion battery is held and grabbed by the suction cup 303, it will enter between the corresponding two clamping rods 310. Then, during the rotation of the rotary drum 301 driving the suction cup 303, with the clamping of the two clamping rods 310, it can be avoided that the finished lithium-ion battery skews during the rotation and swing process, and the stability of the lithium-ion battery during the rotation and swing to adjust the posture can be effectively guaranteed. By setting one end of the ring plate 307 close to the clamping rod 310 as an outwardly inclined structure, the ends of the two paired ring plates 307 together form an outwardly expanding V-shaped structure, which can guide the finished lithium-ion battery during the entry process, and is beneficial to improving the smooth stability of the finished lithium-ion battery entering between the two symmetrically arranged ring plates 307.

[0031] Meanwhile, by rotatably installing a plurality of rollers 311 on the lower end wall at the rear of the ring plate 307, after the finished lithium-ion battery is held by the suction cup 303 and rotates clockwise backward by more than 180°, the finished lithium-ion battery slides downward under the action of gravity, and its end will contact the inner end wall of the ring plate 307. A large number of rotatably installed first nozzles 207 can convert the original sliding friction into rolling friction, greatly reducing the frictional resistance received at the end of the finished lithium-ion battery, and can improve the smoothness of the finished lithium-ion battery during the clockwise swing adjustment to a certain extent.

[0032] In the specific implementation process, as Figure 10 and Figure 12 shown, a transmission pipe 312 is rotatably installed at the inner center position of the circular plate 3, and the transmission pipe 312 is fixedly inserted into the inner center position of the rotary drum 301. A servo motor 313 is installed on the outer side of the circular plate 3, and the drive shaft of the servo motor 313 is in transmission connection with the transmission pipe 312. A vacuum generator 314 is installed on the outer side of the circular plate 3, and an insertion pipe 315 movably inserted into the transmission pipe 312 is connected to the negative pressure air extraction port of the vacuum generator 314. Matching butting ports are provided on the transmission pipe 312 and the insertion pipe 315. During the operation of the device, the servo motor 313 is powered on and started, and drives the transmission pipe 312 to rotate through transmission, and then drives the rotary drum 301 fixedly connected to the transmission pipe 312 to rotate, driving the suction cup 303 to adsorb the finished lithium-ion battery to rotate and adjust the posture clockwise.

[0033] When using the suction cup 303 to adsorb and connect the finished lithium-ion battery, the air inlet of the vacuum generator 314 is connected to an air pump, and the high-speed flowing air enters through the air inlet of the vacuum generator 314 and then sprays out through the air outlet of the vacuum generator 314. During this process, a negative-pressure suction air flow is formed at the negative-pressure air extraction port of the vacuum generator 314. Through the connection of the intubation 315 and the rotational connection between the intubation 315 and the transmission pipe 312, and in cooperation with the connection between the transmission pipe 312 and the inside of the rotating cylinder 301, the suction air flow can act on the inside of the suction cup 303 through the connecting pipe 302, forming a negative-pressure suction force at the suction cup 303 to stably hold and connect the finished lithium-ion battery in contact with the suction cup 303. A plurality of straight pipes 2 and corresponding circular plates 3 can be arranged side by side. The plurality of rotating cylinders 301 are fixedly connected through the transmission pipe 312 for unified driving, and unified air flow suction is carried out through the intubation 315, which is convenient to operate and can effectively improve the transfer efficiency of the finished lithium-ion battery from the first electric conveyor belt 1 to the second electric conveyor belt 4.

[0034] In the specific implementation process, as Figure 1 、 Figure 8 and Figure 12 shown, a refrigeration box 5 is connected between the air outlet of the vacuum generator 314 and the air pipe 206. The outer sides of the front and rear ends of the straight pipe 2 are fixedly installed with annular pipes 501 arranged in a surrounding manner. The second nozzles 502 arranged in a surrounding manner are fixedly embedded in the front and rear side ports of the straight pipe 2, and the second nozzles 502 are communicated with the annular pipes 501 at the corresponding positions. A suction pump 503 is installed on the outer side of the straight pipe 2, and the air inlet and air outlet of the suction pump 503 are respectively communicated with the front and rear annular pipes 501. During the operation of the device, the air flow sprayed out from the air outlet of the vacuum generator 314 enters the air pipe 206 after passing through the refrigeration box 5, and then is sprayed into the straight pipe 2 through the first nozzle 207. Since the air flow passes through the refrigeration box 5 before entering the air pipe 206, the air flow will be cooled by the refrigeration box 5, making the air flow sprayed into the straight pipe 2 in a low-temperature state. Thus, it can effectively improve the heat dissipation and cooling efficiency of the device during the transportation of the in-situ polymerized finished lithium-ion battery conveyed in the straight pipe 2 through the cold air jet, enabling the length of the second section of transportation to be greatly reduced and facilitating the increase of the speed of the finished lithium-ion battery during the second section of transportation.

[0035] Meanwhile, during the process of using a cold air flow to blow and reduce the temperature of the in-situ polymerization product of the lithium-ion battery during its transportation in the straight pipe 2, the pumping unit 503 is powered on and started. Since the air inlet and outlet of the pumping unit 503 are respectively connected to the annular pipes 501 arranged around the front and rear ends of the straight pipe 2 on the outside, the air flow in the straight pipe 2 can be drawn out through the second nozzles 502 distributed around one end and ejected through the second nozzles 502 distributed around the other end. A large number of second nozzles 502 are distributed around the port of the straight pipe 2. During the air flow process, an air curtain can be formed, reducing the efficiency of the cold air flow in the straight pipe 2 from escaping outward, which is conducive to ensuring the stability of the in-situ polymerization product of the lithium-ion battery in cooling and dissipating heat in the straight pipe 2.

[0036] Specifically, the working principle and operation method of the present invention are as follows: The just-processed in-situ polymerization product of the lithium-ion battery is longitudinally placed flat on the first electric conveyor belt 1 and is conveyed from left to right by the first electric conveyor belt 1. Then, through the rapid push of the telescopic end of the electric push rod 101, the in-situ polymerization product of the lithium-ion battery is pushed into the straight pipe 2 from the front end, so that the lithium-ion battery product is erected on the first spiral roller 201 and the second spiral roller 202. The external motor is powered on and started to drive the rotating rod 205 to rotate. Through transmission connection, the first spiral roller 201 is driven to rotate. Then, by means of the meshing of the first gear 203 and the second gear 204, the second spiral roller 202 is driven to rotate in the opposite direction relative to the first spiral roller 201. The axial conveying force when the first spiral roller 201 and the second spiral roller 202 rotate relatively, in cooperation with the contact friction force between the first spiral roller 201, the second spiral roller 202 and the lithium-ion battery product, drives the lithium-ion battery product to be stably conveyed backward in the straight pipe 2. During this process, the air flow is supplied into the air supply pipe 206 through the refrigeration box 5, so that the cold air flow is sprayed backward obliquely in the straight pipe 2 through the first nozzle 207. Through the blowing of the cold air flow, the in-situ polymerization product of the lithium-ion battery is rapidly cooled during its transportation in the straight pipe 2. Synchronously, the air flow forms an air curtain at the front and rear ends of the straight pipe 2 through the cooperation of the annular pipe 501, the second nozzle 502 and the pumping unit 503, ensuring the low-temperature stability in the straight pipe 2; After the finished lithium-ion battery is conveyed to the ends of the first spiral roller 201 and the second spiral roller 202, the vacuum generator 314 provides air flow suction into the rotating cylinder 301 through the connection of the insertion tube 315. Under the communication of the connecting pipe 302, negative pressure adsorption is formed in the suction cup 303 through air flow suction, and the finished lithium-ion battery is adsorbed and connected by the suction cup 303. Then, the servo motor 313 drives the transmission pipe 312 to drive the rotating cylinder 301 to rotate, so that the rotating cylinder 301 drives the finished lithium-ion battery adsorbed and connected on the suction cup 303 to rotate 270° clockwise backward. The originally longitudinally placed finished lithium-ion battery is converted into an upright state. Under the action of gravity, the suction cup 303 at the lowermost position moves downward driven by the falling of the finished lithium-ion battery, so that the air leakage hole 306 is exposed from the suction cup 303, and the negative pressure suction in the suction cup 303 is released, so that the lithium-ion battery falls vertically onto the second electric conveyor belt 4 below, and then is continuously conveyed to the right in an upright state for subsequent other processing.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
