Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production, and in particular discloses an automatic feeding mechanism for lithium battery winding. Background Art

[0002] In the field of lithium battery production, traditional winding and loading methods usually rely on a lot of manual operations. In the unwinding, winding and loading links, workers are often required to manually carry the unwinding roller, install and fix it, and adjust the winding length. This method is not only labor-intensive, but also inefficient, prone to human errors, and affects product quality. For product quality control, the traditional method lacks effective correction devices and multi-dimensional robot drives, which can easily lead to undesirable phenomena such as uneven winding and wrinkles. At the same time, due to the imperfect mechanical drive design of each link, the stability of the production process is insufficient, and it is easily affected by external factors, further reducing product quality.

[0003] In terms of equipment adaptability, the various devices of traditional equipment are usually designed in a relatively fixed manner, making it difficult to adapt to the requirements of lithium battery winding of different specifications. The lack of adjustability and universal design requires a lot of transformation and adjustment of the equipment when facing different production tasks, which increases production costs and time costs. Moreover, due to the unreasonable mechanical drive design, the stability of the production process is poor, and vibration and shaking are prone to occur, which affects the service life and production efficiency of the equipment. For this reason, it is necessary to provide a lithium battery winding automatic feeding mechanism with a high degree of automation, high production efficiency, high product quality, and high adaptability and stability. Utility Model Content

[0004] In order to overcome the shortcomings and deficiencies in the prior art, the utility model aims to provide an automatic feeding mechanism for lithium battery winding.

[0005] To achieve the above-mentioned purpose, the utility model provides an automatic loading mechanism for lithium battery winding, comprising a frame, a feeding device, a reeling device and a reeling device arranged on the frame, the reeling device and the feeding device are below the reeling device, the feeding device has a feeding trolley, a supporting shaft is provided on the feeding trolley, an unwinding roller is sleeved on the supporting shaft, the unwinding device comprises a manipulator and a clamping assembly, the reeling device comprises a first rewinding assembly reciprocatingly arranged on the frame, a rewinding drive assembly driving the first rewinding assembly to move, and a second rewinding assembly, a rewinding roller is arranged between the first rewinding assembly and the second rewinding assembly, the feeding trolley sends the unwinding roller to a preset position, the manipulator drives the clamping assembly to clamp the unwinding roller for fixing, and the first rewinding assembly approaches / moves away from the second rewinding assembly to adjust the rewinding length of the rewinding roller.

[0006] The feeding vehicle can automatically deliver the unwinding roller to the preset position. The manipulator-driven clamping component can quickly clamp and fix the unwinding roller, which can improve the automation degree of the production process and also enhance the production efficiency. The clamping component can stably clamp the unwinding roller, avoiding shaking or displacement during the winding process, ensuring the neatness and precision of the lithium battery winding. The precise adjustment of the winding length can ensure the dimensional consistency of the lithium battery winding and improve the quality stability of the product.

[0007] Furthermore, a third support frame is provided at the end of the manipulator. The clamping component is connected to the third support frame. The number of clamping components is set to two and the structures of the two clamping components are the same. The clamping component includes a carrier frame arranged on the third support frame, a clamp reciprocatingly arranged on the carrier frame, and a clamping driver for driving the clamp to reciprocate. Two strip-shaped holes are formed on the third support frame for installing the two clamping components respectively, and the carrier frame is detachably connected to the third support frame; the clamp has a first clamping arm connected to the carrier frame and a second clamping arm detachably connected to the carrier frame. The two first clamping arms and the two second clamping arms cooperate to clamp the roller necks at both ends of the unwinding roller for fixation. A plurality of rolling elements are provided on the arc surface of the clamping arm for cooperating to clamp the roller neck, and the plurality of rolling elements are in rolling contact with the roller neck.

[0008] The two clamping components act on the roller necks at both ends of the unwinding roller simultaneously, which can apply force evenly from both ends, ensuring that the unwinding roller is more stable during the clamping process and will not tilt or shake, improving the stability and precision of clamping. The plurality of rolling elements are in rolling contact with the roller neck, reducing the frictional resistance between the clamping arm and the roller neck, making the clamping and releasing processes smoother, and at the same time reducing the wear on the roller neck, ensuring the surface quality and precision of the unwinding roller. The carrier frame is detachably connected to the third support frame, which is convenient for replacement and adjustment according to different sizes and shapes of the unwinding roller, improving the adaptability of the equipment. The second clamping arm is detachably connected to the carrier frame, and the two strip-shaped holes on the third support frame are used for installing the clamping components, enabling the position of the clamping components to be adjusted within a certain range to adapt to unwinding rollers of different lengths, enhancing the flexibility of the equipment. The clamping and releasing actions can be quickly achieved, improving the working efficiency. At the same time, the automated clamping process reduces the time and error of manual operation, improving the consistency and reliability of production.

[0009] Furthermore, the first winding component has a first mounting seat reciprocatingly arranged on the frame. A winding driver is provided on the first mounting seat. A first conical rotating member is provided on the output shaft of the winding driver. The inner circumference of the first conical rotating member is connected to a second winding roller, and the outer circumference is connected to a first winding roller. The length of the first winding roller is less than the length of the second winding roller. The first winding roller is set as a sponge roller, and a water tank cooperating with the sponge roller is provided on the first mounting seat.

[0010] Through the reciprocating motion of the first mounting seat on the frame, the positions of the first winding roller and the second winding roller relative to other components can be changed, thereby achieving flexible adjustment of the overall length of the winding rollers. This enables the mechanism to adapt to the winding requirements of lithium batteries with different length specifications, improving the versatility and adaptability of the equipment. The combined use of the first winding roller and the second winding roller allows for the selection of winding rollers with different lengths for operation according to actual needs. The water tank supplies water to the sponge roller. Before the winding operation starts, the free end of the diaphragm coil material gets wet and can be evenly attached to the sponge roller without easily spreading, which can provide quality assurance for the subsequent winding work.

[0011] Furthermore, the manipulator includes a first support frame reciprocatingly arranged on the frame, a first driver for driving the first support frame, a second support frame reciprocatingly arranged on the first support frame, a second driver for driving the second support frame, a third support frame reciprocatingly arranged on the second support frame, and a third driver for driving the third support frame. The third support frame is connected to the clamping assembly.

[0012] The combination of multiple support frames and their respective corresponding drivers enables the manipulator to perform precise reciprocating motions in multiple directions. This multi-dimensional motion ability allows the manipulator to adapt to unwinding rollers in different positions and postures, improving the flexibility and adaptability of the equipment and enabling it to handle various complex working scenarios. Each driver can quickly drive the corresponding support frame to move as needed, thereby quickly moving the manipulator to the target position, reducing the operation time, and improving the work efficiency. The independent control of multiple drivers can achieve precise adjustment of each part of the manipulator, thereby accurately positioning the clamping assembly at the neck position of the unwinding roller to ensure the accuracy and stability of clamping.

[0013] Furthermore, the automatic feeding mechanism for lithium battery winding further includes a deviation rectifying device arranged on an external bearing plane. The deviation rectifying device has a first support seat and a second support seat. A deviation rectifying motor is provided on the first support seat. Two synchronous wheels rotatably connected to the support seats are arranged in parallel on the first support seat and the second support seat.

A second mounting seat is provided on the second support seat. A reciprocating deviation rectifying sensor and a second deviation rectifying driver for driving the sensor are provided on the second mounting seat.

[0014] The cooperation between the photodiode and the deviation rectifying sensor can detect the position deviation of the unwinding roller or the winding roller in real time. When a deviation occurs, the deviation rectifying device can make timely adjustments to ensure that the lithium battery remains in the correct position during the winding process, improving the winding accuracy and quality. The deviation rectifying motor drives the first mounting plate to move through the synchronous pulley and the synchronous belt, realizing the position adjustment of the photodiode and the precise control of the deviation rectifying driver over the photodiode and the deviation rectifying sensor. The entire deviation rectifying process has a high degree of automation and does not require manual intervention. The first deviation rectifying driver and the second deviation rectifying driver can respectively adjust the positions of the photodiode and the deviation rectifying sensor, enabling them to adapt to unwinding rollers and winding rollers of different sizes, as well as different winding speeds and tension requirements.

[0015] Furthermore, the automatic loading mechanism for lithium battery winding further includes a limiting device arranged on the frame and used in cooperation with the feeding device. The limiting device includes a plurality of first limiting wheels and a plurality of second limiting wheels that are arranged in parallel on both sides of the frame and rotatably connected to the frame. The rotation axes of the plurality of first limiting wheels are parallel to each other, and the rotation axes of the plurality of second limiting wheels are parallel to each other. The rotation axis of the first limiting wheel and the rotation axis of the second limiting wheel are perpendicular to each other; the first limiting wheels and the second limiting wheels cooperate to abut against the free ends on both sides and the bottom of the feeding cart.

[0016] The plurality of first limiting wheels and the second limiting wheels limit the feeding cart from different directions, which can effectively prevent the feeding cart from shifting, shaking, etc. during the movement, ensuring that the feeding cart can accurately deliver the unwinding roller to the preset position and improving the feeding accuracy. Abutting and limiting the free end at the bottom of the feeding cart can also prevent the feeding cart from tilting or overturning when carrying the unwinding roller, further ensuring the safety of the operation. The limiting wheels are rotatably connected to the frame. When the feeding cart moves, the limiting wheels can rotate along with the movement of the cart, reducing the frictional resistance and making the feeding process smoother. At the same time, this rotatable connection method also reduces the wear of the feeding cart and the limiting wheels, improving the service life and stability of the equipment.

[0017] Furthermore, the automatic loading mechanism for lithium battery winding further includes a glue pasting device arranged on the frame. The glue pasting device is above the unwinding roller and the winding assembly. The glue pasting device includes a connecting rod that reciprocates on the frame, a glue pasting roller rotatably arranged on the connecting rod, and a glue pasting driver that drives the connecting rod to move.

[0018] The glue - sticking driver drives the connecting rod to move, which can quickly move the glue - sticking roller to the position where glue - sticking is required, realizing automated glue - sticking operation and improving the efficiency of glue - sticking. The rotatably - arranged glue - sticking roller can ensure that the tape is evenly attached to the lithium - battery winding, avoiding poor glue - sticking phenomena such as wrinkles and bubbles, and improving the quality of glue - sticking. The position and pressure of the glue - sticking roller can be precisely controlled through the connecting rod and the glue - sticking driver, ensuring a tight fit between the tape and the winding material, and enhancing the stability and reliability of glue - sticking. The size and material of the glue - sticking roller can be selected and replaced according to different tape types, improving the versatility and adaptability of the equipment.

[0019] Further, the second winding assembly has a second mounting plate arranged on the frame. A winding guide rail is provided on the second mounting plate. A winding slider is provided on the winding guide rail. A third mounting seat is provided on the winding slider. A winding spring is provided on the third mounting seat. The winding spring is between the second mounting plate and the third mounting seat, and both ends of the winding spring are connected to the third mounting seat. A second conical rotating member is rotatably provided on the third mounting seat.

[0020] The elastic buffering effect can make the winding process smoother. When the first winding assembly reciprocates on the frame, the first and second winding rollers may collide with the second conical rotating member. The presence of the winding spring can reduce the collision and ensure the position accuracy of the second conical rotating member, enhancing the stability of the winding process. The cooperation of the winding guide rail and the winding slider can ensure that the third mounting seat moves smoothly within a certain range, thus ensuring the position accuracy of the second conical rotating member. This helps to improve the winding accuracy of the lithium - battery winding, making the wound product neater and more beautiful. Precise position control can reduce the deviation during the winding process and improve the quality stability of the product.

[0021] Further, a handle for pushing and pulling the feeding cart is provided on the feeding cart. Support columns are provided at the bottom of the feeding cart. A roller and a rotating shaft are rotatably provided on the support column. A stop member is provided on the rotating shaft, and the stop member rotates and abuts against the roller to stop the roller from rolling.

[0022] The setting of the handle facilitates the operator to push and pull the feeding cart. The co - existence of manual and automated settings can better cope with different working conditions. The rotation of the roller and the control of the stop member can make the movement and stop of the feeding cart more stable and reliable, reducing the vibration and impact of the equipment, and improving the service life and stability of the equipment.

[0023] Further, the driver has a driving motor. A lead screw is provided on the output shaft of the driving motor. A driving slider is screwed on the lead screw. Two anti - collision members for preventing the driving slider from colliding with other components are respectively provided at both ends of the lead screw.

[0024] The rotation of the roller and the control of the stopper can make the movement and stop of the feeding vehicle more stable and reliable, reduce the vibration and impact of the equipment, and improve the service life and stability of the equipment. The driving motor drives the lead screw to rotate through the output shaft. Since the driving slider is screwed to the lead screw, the rotational motion of the lead screw can be converted into the linear motion of the driving slider. This transmission method can achieve precise position control to ensure that the fixture or other moving parts can accurately reach the predetermined position.

Two strip holes 324 are formed on the third support frame 315 for installing the two clamping components 32 respectively. The carrier 321 is detachably connected to the third support frame 315. The clamp 322 has a first clamping arm 3221 connected to the carrier 321 and a second clamping arm 3222 detachably connected to the carrier 321.

A plurality of rolling elements 3223 are provided on the arc surface of the clamping arm for cooperating to clamp the roller neck, and the plurality of rolling elements 3223 are in rolling contact with the roller neck.

[0042] During actual use, the two clamping components 32 act on the roller necks at both ends of the unwinding roller 23 simultaneously, capable of applying forces evenly from both ends, ensuring that the unwinding roller 23 is more stable during the clamping process, without tilting or shaking, improving the stability and precision of clamping. Multiple rolling elements 3223 are in rolling contact with the roller necks, reducing the frictional resistance between the clamping arms and the roller necks, making the clamping and releasing processes smoother, and at the same time reducing the wear on the roller necks, ensuring the surface quality and precision of the unwinding roller 23. The carrier 321 is detachably connected to the third support frame 315, facilitating replacement and adjustment according to the sizes and shapes of different unwinding rollers 23, improving the adaptability of the equipment.

A second conical rotating member 436 is rotatably provided on the third mounting seat 434.

[0054] During actual use, the elastic buffering effect can make the winding process more stable. When the first winding assembly 41 reciprocates on the frame 1, the first and second winding rollers 415 may collide with the second conical rotating member 436. The presence of the winding spring 435 can reduce the collision and ensure the position accuracy of the second conical rotating member 436, improving the stability of the winding process. The cooperation of the winding guide rail 432 and the winding slider 433 can ensure that the third mounting seat 434 moves smoothly within a certain range, thereby ensuring the position accuracy of the second conical rotating member 436. This helps to improve the winding accuracy of the lithium - battery, making the wound product neater and more beautiful. Precise position control can reduce the deviation during the winding process and improve the quality stability of the product.

[0055] Specifically, a handle 211 for pushing and pulling the feeding cart 21 is provided on the feeding cart 21. Support columns 212 are provided at the bottom of the feeding cart 21. A roller 213 and a rotating shaft 214 are rotatably provided on the support columns 212. A stopper 215 is provided on the rotating shaft 214. The stopper 215 rotates and abuts against the roller 213 to stop the roller 213 from rolling.

[0056] During actual use, the setting of the handle 211 facilitates the operator to push and pull the feeding cart 21. The co - existence of manual and automated settings can better cope with different working conditions. The rotation of the roller 213 and the control of the stopper 215 can make the movement and stop of the feeding cart 21 more stable and reliable, reducing the vibration and impact of the equipment, and improving the service life and stability of the equipment.

[0057] Specifically, the driver has a driving motor 3121. A lead screw 3122 is provided on the output shaft of the driving motor 3121. A driving slider 3123 is screwed onto the lead screw 3122. Two anti-collision members 3124 for preventing the driving slider 3123 from colliding with other components are respectively provided at both ends of the lead screw 3122.

[0058] During actual use, the rotation of the roller 213 and the control of the stopper 215 can make the movement and stop of the feeding vehicle 21 more stable and reliable, reduce the vibration and impact of the equipment, and improve the service life and stability of the equipment. The driving motor 3121 drives the lead screw 3122 to rotate through the output shaft. Since the driving slider 3123 is screwed onto the lead screw 3122, the rotational motion of the lead screw 3122 can be converted into the linear motion of the driving slider 3123. This transmission method can achieve precise position control, ensuring that the fixture 322 or other moving components can accurately reach the predetermined position.
