Description

Technical Field

[0001] This invention relates to the field of battery cell coating technology, specifically to a battery cell preparation system and its application method. Background Technology

[0002] The coating preparation of cylindrical battery cells is a key process in lithium battery manufacturing to achieve cell fixation, insulation, thermal conductivity and sealing. The core is to uniformly coat the outer wall, bottom, tab perimeter or module assembly surface of the cylindrical cell shell with special adhesives such as two-component thermally conductive silicone, structural adhesive, epoxy adhesive or UV adhesive using high-precision methods such as micro-concave roller coating, screw valve dispensing, spiral spraying.

[0003] However, existing technologies have problems such as inaccurate tolerances during cell processing, which cannot meet the precise clamping requirements of the glue application station, thus affecting the subsequent glue application effect. Furthermore, there are still issues where glue drips from the glue application head at the end of the glue application mechanism after it has just been closed. This can easily lead to glue waste and glue dripping onto the cell surface, affecting the glue application effect, as the cell loading and unloading is completed at a single station. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that the device cannot meet the precise clamping of the glue coating station due to the inaccurate error tolerance during cell processing, thus affecting the subsequent glue coating effect. In addition, there is still a problem that the glue injection head at the end of the glue injection mechanism after it is closed will drip some glue, which will easily cause glue waste and drip onto the surface of the cell and affect the glue coating effect when the cell is picked up and put in a single station. Therefore, a battery cell preparation system is proposed.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A battery cell manufacturing system is designed, including a column and a platform. The platform is fixedly connected to the lower outer wall of the column, and platform supports are fixedly connected to the four corners of the lower end of the platform. A lifting cylinder is fixedly connected to the left side of the upper outer wall of the column. A sleeve is fixedly connected to the end of the output shaft of the lifting cylinder. The inner wall of the sleeve is slidably connected to the column. A reciprocating assembly is installed at the upper end of the platform, and a rotating assembly is arranged above the sliding platform in the reciprocating assembly.

[0006] Preferably, the reciprocating assembly includes a transverse slide rail, a collecting cylinder, a bottom platform, a magnetic couple rodless cylinder, and a sliding platform; The magnetic coupler rodless cylinder is fixedly connected to the upper rear side of the platform. The output end of the magnetic coupler rodless cylinder is fixedly connected to a sliding platform. The lower ends of the sliding platform are slidably connected to transverse slide rails. The lower ends of the transverse slide rails are fixedly connected to the platform. The bottom platform is fixedly connected to the lower inner wall of the platform support. The inner walls on both sides of the bottom platform contain material collection cylinders. This design, through the use of a magnetic coupler rodless cylinder, a sliding platform, a collection cylinder, and a glue injection mechanism, allows the magnetic coupler rodless cylinder to move the sliding platform away from the left-side workstation. This ensures that the glue injection mechanism on the left is positioned directly below the collection cylinder on the left. The glue injection head at the end of the recently closed mechanism will drip some glue. This glue droplet will not affect the battery cell already glued and located on the right-side workstation; instead, it will pass directly through the corresponding notch on the platform into the collection cylinder for storage, thus protecting the battery cell and preventing glue waste.

[0007] Preferably, the platform above the collecting cylinder is machined with a corresponding notch, and a protective cover is fixed to the upper outer edge of the sliding platform. Preferably, a crossbeam is fixedly connected to the right side of the outer wall of the sleeve, and an adhesive injection mechanism is fixedly connected to both ends of the crossbeam. Preferably, the lower end of the glue injection mechanism is machined with a glue injection head, and the outer wall of the glue injection mechanism is equipped with a glue replenishing head.

[0008] This setup, through the design of the glue injection mechanism, servo motor, battery cell, and disc, allows the servo motor to be started before the glue injection mechanism is activated. The servo motor drives the disc, which in turn drives the battery cell to rotate at a constant speed. The glue injection mechanism then applies glue to the upper surface of the battery cell. The specific weight of the glue applied can be detected by the change in the value of the electronic balance.

[0009] Preferably, the rotating assembly includes an electronic balance, an arc plate, a cylinder, rollers, a vertical rod, a horizontal plate, a servo motor, a base, a bottom block, a double-headed cylinder, and a disc; The electronic balance is fixedly connected to the upper center of the sliding platform. The upper end of the electronic balance is fixedly connected to the servo motor via a base. A horizontal plate is fixedly connected to the end of the output shaft of the servo motor. The upper front and rear sides of the horizontal plate are fixedly connected to a disc. A double-headed cylinder is fixedly connected to the upper center of the horizontal plate. Vertical rods are fixedly connected to the ends of the output shafts on both sides of the double-headed cylinder. A bottom block is fixedly connected to the lower end of the vertical rod. The vertical rod and the bottom block are slidably connected to the horizontal plate. The upper part of the vertical rod is fixedly connected to a cylinder via bolts. Arc-shaped plates are fixedly connected to the upper and lower sides of the outer wall of the cylinder. Rollers are rotatably connected to the inner wall of the end of the arc-shaped plates. This setup, through the design of a double-headed cylinder, vertical rods, rollers, an arc-shaped plate, and the battery cell, allows the double-headed cylinder to drive the vertical rods on both sides to move inward synchronously. Consequently, the rollers on both sides move inward to complete the center positioning and clamping of the battery cell. Furthermore, due to the arc-shaped design of the arc-shaped plate and the design of the four rollers, it can be used for clamping and positioning battery cells of different sizes within a certain range.

[0010] Preferably, a battery cell is placed above the disk, and the outer wall of the battery cell is in contact with the outer wall of the roller. Preferably, a protective frame is fixed to the right side of the center of the outer wall of the column.

[0011] How to use the battery cell manufacturing system: S1. First, the user can assemble the overall structure. When in use, connect the external glue supply hose to the glue head to ensure that the glue injection mechanism is always in use. Then, control the magnetic coupler rodless cylinder to move the sliding platform to the left side, so that it is directly below the protective frame. Place the battery cell that needs to be glued on the top of the disc. Then, control the output shafts on both sides of the double-headed cylinder to retract, so that the double-headed cylinder can drive the vertical rods on both sides to move inward synchronously. In turn, the rollers on both sides move inward to complete the center positioning and clamping of the battery cell. Due to the arc design of the arc plate and the design of the four rollers, it can be used for clamping and positioning battery cells of different sizes within a certain range. This effectively avoids the problem that the accuracy of the glue application station cannot be met due to the inaccuracy of the error tolerance during battery cell processing, which would affect the subsequent glue application effect. S2. After clamping the battery cell, control the magnetic coupler rodless cylinder to move the sliding platform to directly below the glue injection mechanism on the left. At this time, control the lifting cylinder to move the glue injection mechanism downward so that the glue injection head is in contact with the glue injection position of the battery cell. Before opening the glue injection mechanism, control the servo motor to start so that the servo motor can drive the disc and then drive the battery cell to rotate at a constant speed. The glue injection mechanism will inject glue onto the upper surface of the battery cell. The specific glue weight can be detected by the change of the value of the electronic balance. S3. After the glue application is completed, close the glue injection mechanism. Simultaneously control the lifting cylinder to move the glue injection mechanism upward, and control the sliding platform to move directly below the glue injection mechanism on the right. At this time, the sliding platform clears the position of the left station, so that the bottom of the left glue injection mechanism is exactly aligned with the left collection cylinder. The glue injection head at the end of the glue injection mechanism that has just been closed will have some glue dripping down. At this time, the glue dripping will not affect the battery cell that has been glued and is located at the right station. Instead, it will directly pass through the corresponding notch on the platform and enter the collection cylinder for storage, thus protecting the battery cell and preventing glue waste. This effectively avoids the problem of glue waste and glue dripping onto the battery cell surface, which is easily caused by glue dripping from the glue injection head at the end of the glue injection mechanism that has just been closed when the battery cell is picked up and put down in a single station. Control the double-headed cylinder to move the vertical rods and rollers on both sides outward, and then take out the battery cell. The above operation can be repeated to complete the continuous battery cell glue preparation process.

[0012] The battery cell manufacturing system and its usage method proposed in this invention have the following advantages: Through the coordination of a magnetic coupler rodless cylinder, a sliding platform, a protective shield, vertical rods, a double-headed cylinder, an arc plate, and rollers, the magnetic coupler rodless cylinder is controlled to move the sliding platform to the left, placing it directly below the protective frame. The battery cell to be coated is then placed above the disc. Subsequently, the output shafts on both sides of the double-headed cylinder are retracted, allowing the double-headed cylinder to drive the vertical rods on both sides to move inward synchronously. Consequently, the rollers on both sides move inward to complete the center positioning and clamping of the battery cell. Furthermore, due to the arc design of the arc plate and the design of the four rollers, it can be used for clamping and positioning battery cells of different sizes within a certain range. This effectively avoids the problem that the inaccurate tolerance during battery cell processing cannot meet the precise clamping requirements of the coating station, thus affecting the subsequent coating effect. Through the coordination of the glue injection mechanism, the magnetic coupler rodless cylinder, the collection cylinder, the glue injection head, the battery cell, and the sliding platform, after the glue application is completed and the glue injection mechanism is closed, the lifting cylinder is simultaneously controlled to move the glue injection mechanism upwards, and the magnetic coupler rodless cylinder controls the sliding platform to move directly below the glue injection mechanism on the right. At this time, the sliding platform clears the position of the left station, so that the bottom of the left glue injection mechanism is exactly aligned with the left collection cylinder. The glue injection head at the end of the glue injection mechanism that has just been closed will have some glue dripping down. At this time, the glue dripping will not affect the battery cell that has been glued and is located at the right station. Instead, it will directly pass through the corresponding notch on the platform and enter the collection cylinder for storage. This protects the battery cell and prevents glue waste. In this way, the problem of glue dripping from the glue injection head at the end of the glue injection mechanism that has just been closed and is used for battery cell loading and unloading at a single station is avoided, which can easily lead to glue waste and dripping onto the battery cell surface, affecting the glue application effect.

[0015] The present invention will be further described below with reference to the accompanying drawings: See attached document Figure 1-8 In this embodiment, a battery cell manufacturing system includes a column 1 and a platform 2. The platform 2 is fixedly connected to the lower outer wall of the column 1, and platform brackets 13 are fixedly connected to the four corners of the lower end of the platform 2.

A sleeve 8 is fixedly connected to the end of the output shaft of the lifting cylinder 7.

The injection mechanism 10 can squeeze external glue from the injection head 11. A glue replenishing head 14 is installed on the outer wall of the injection mechanism 10. A protective frame 6 is fixedly connected to the right side of the center of the outer wall of the column 1. See attached document Figure 1-8 In this embodiment, the reciprocating component 3 includes a transverse slide rail 301, a collecting cylinder 302, a bottom platform 303, a magnetic couple rodless cylinder 304, and a sliding platform 305. The magnetic coupler rodless cylinder 304 is fixedly connected to the upper rear side of the platform 2. The output end of the magnetic coupler rodless cylinder 304 is fixedly connected to the sliding platform 305. The model of the magnetic coupler rodless cylinder 304 can be determined according to the specific application. The lower ends of the sliding platform 305 are slidably connected to the two sides of the transverse slide rail 301.

[0017] The sliding platform 305 can move left and right on the outer wall of the transverse slide rail 301. The lower end of the transverse slide rail 301 is fixedly connected to the platform 2. The bottom platform 303 is fixedly connected to the lower inner wall of the platform support 13. The inner walls on both sides of the bottom platform 303 store the collection cylinder 302. The platform 2 above the collection cylinder 302 has a corresponding notch. The upper outer edge of the sliding platform 305 is fixedly connected to a protective cover 5. The protective cover 5 can protect the electronic balance 401 and other structures from damage when the battery cell 12 is placed in. See attached document Figure 1-8 In this embodiment, the rotating assembly 4 includes an electronic balance 401, an arc plate 402, a cylinder 403, a roller 404, a vertical rod 405, a horizontal plate 406, a servo motor 407, a base 408, a bottom block 409, a double-headed cylinder 410, and a disc 411. An electronic balance 401 is fixedly connected to the upper center of the sliding platform 305. The model of the electronic balance 401 can be determined according to the specific application. The upper end of the electronic balance 401 is fixedly connected to the servo motor 407 via the base 408. The model of the servo motor 407 can be determined according to the specific application. A horizontal plate 406 is fixedly connected to the end of the output shaft of the servo motor 407. The front and rear sides of the upper end of the horizontal plate 406 are fixedly connected to the disc 11. A double-headed cylinder 410 is fixedly connected to the upper center of the horizontal plate 406. The model of the double-headed cylinder 410 can be determined according to the specific application.

[0018] Vertical rods 405 are fixed to the ends of the output shafts on both sides of the double-headed cylinder 410. A base block 409 is fixed to the lower end of the vertical rod 405. The vertical rod 405 and the base block 409 are slidably connected to the horizontal plate 406. The upper part of the vertical rod 405 is fixedly connected to the cylinder 403 by bolts. The cylinder 403, the arc plate 402 and the roller 404 can be installed or disassembled on the vertical rod 405 according to the bolts. Arc plates 402 are fixed to both the upper and lower sides of the outer wall of the cylinder 403. The inner wall of the end of the arc plate 402 is rotatably connected to the roller 404. A battery cell 12 is placed on the top of the disc 411. The battery cell 12 is cylindrical in shape. The outer wall of the battery cell 12 is in contact with the outer wall of the roller 404. The magnetic couple rodless cylinder 304, the lifting cylinder 7 and the double-headed cylinder 410 are all self-locking cylinders. How to use the battery cell manufacturing system: S1. When this battery cell preparation system is needed, the user can first assemble the overall structure. During use, connect the external glue supply hose to the glue filling head 14 so that the glue injection mechanism 10 is always in a glue-filled state. Then, control the magnetic couple rodless cylinder 304 to move the sliding platform 305 to the left side, so that it is directly below the protective frame 6. Place the battery cell 12 that needs to be glued on above the disc 411. Then control the output shafts on both sides of the double-headed cylinder 410 to retract, so that the double-headed cylinder 410 can drive the vertical rods 405 on both sides to move inward synchronously. Then, the rollers 404 on both sides move inward to complete the center positioning and clamping of the battery cell 12. Due to the arc design of the arc plate 402 and the design of the four rollers 404, it can be used to clamp and position battery cells 12 of different sizes within a certain range. This effectively avoids the problem that the inaccurate tolerance of the battery cell processing cannot meet the precise clamping of the glue application station, thus affecting the subsequent glue application effect.

[0019] S2. After clamping the battery cell 12, control the magnetic couple rodless cylinder 304 to move the sliding platform 305 to directly below the glue injection mechanism 10 on the left. At this time, control the lifting cylinder 7 to drive the glue injection mechanism 10 to move downward, so that the glue injection head 11 is attached to the glue injection position of the battery cell 12. Before opening the glue injection mechanism 10, control the servo motor 407 to start, so that the servo motor 407 can drive the disc 411 and thus drive the battery cell 12 to rotate at a uniform speed. The glue injection mechanism 10 injects glue onto the upper surface of the battery cell 12. The specific glue weight can be detected by the change in the value of the electronic balance 401.

[0020] S3. After the glue application is completed, the glue injection mechanism 10 is closed. Simultaneously, the lifting cylinder 7 is controlled to move the glue injection mechanism 10 upward, and the magnetic coupler rodless cylinder 304 controls the sliding platform 305 to move directly below the glue injection mechanism 10 on the right. At this time, the sliding platform 305 clears the position of the left station, so that the bottom of the glue injection mechanism 10 on the left corresponds to the left collection cylinder 302 (the corresponding position of the platform 2 has a notch). The glue injection head 11 at the end of the glue injection mechanism 10, which has just been closed, will have some glue dripping down. At this time, the glue dripping will not affect the battery cell 12 that has been glued and is located in the right station, but will directly pass through the platform. The material enters the collection cylinder 302 through the corresponding notch of the plate 2 for storage (the collection cylinder 302 is equipped with an induction heating component to prevent the glue from solidifying). This protects the battery cell 12 and prevents glue waste. In this way, it can effectively avoid the problem that the glue injection head 11 at the end of the glue injection mechanism 10, which has just been closed, will drip some glue. It is easy to cause glue waste and drip onto the surface of the battery cell when the battery cell is picked up and put down in a single station. The double-headed cylinder 410 is controlled to drive the vertical rods 405 on both sides and the roller 404 to move outward. After the battery cell 12 is taken out, the above operation can be repeated to complete the continuous battery cell glue preparation process.

[0021] S4. Finally, the control process in this case can be controlled by a PLC controller, which may include structures such as a magnetic coupler rodless cylinder 304, an electronic balance 401, a servo motor 407, a lifting cylinder 7, a double-headed cylinder 410, and a glue injection mechanism 10. The control content may include specific data control such as control, self-locking, linkage, and stroke.

At this time, the glue dripping will not affect the battery cell that has been glued and is located at the right station. Instead, it will directly pass through the corresponding notch on the platform and enter the collection cylinder for storage, thus protecting the battery cell and preventing glue waste.
