Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production, and particularly discloses an unwinding automatic loading machine for lithium battery production. Background Art

[0002] With the development of lithium-ion batteries in the fields of electric vehicles, consumer electronics, and energy storage, higher requirements are put forward for the comprehensive performance of batteries. The safety issue of lithium-ion batteries is particularly important, especially the problem of internal short circuit of the battery. The separator is an indispensable component in lithium-ion batteries, and its function is to prevent the positive and negative electrodes from contacting and causing a short circuit, and to provide a channel for the migration of lithium ions in the electrolyte. In the production process of lithium batteries, the feeding, gluing, and winding of the separator roll are important and frequent processes. The traditional manual or semi-automatic feeding methods have problems such as low efficiency, insufficient accuracy, and high labor intensity, and are difficult to meet the requirements of modern production lines. Content of the Utility Model

[0003] In order to overcome the disadvantages and deficiencies existing in the prior art, the purpose of the utility model is to provide an unwinding automatic loading machine for lithium battery production.

[0004] To achieve the above purpose, an unwinding automatic loading machine for lithium battery production of the utility model includes a frame, a loading mechanism, a feeding mechanism, a double-sided tape gluing roller, and a winding assembly arranged on the frame; the feeding mechanism is slidably arranged on the frame, and the feeding mechanism is arranged in parallel with the loading mechanism, the double-sided tape gluing roller, and the winding assembly. The loading mechanism includes a manipulator, and the manipulator is slidably arranged on the frame. Clamping assemblies are arranged at both ends of the manipulator. When the feeding mechanism moves to a position flush with the loading mechanism, the clamping assemblies of the loading mechanism clamp both ends of the reel of the external roll placed on the feeding mechanism. The feeding mechanism moves towards the end away from the loading mechanism, and the external roll on the feeding mechanism is separated from the feeding mechanism to complete the loading.

[0005] The external roll is placed on the feeding cart of the feeding mechanism and fixed by a fixing frame and a rod. The feeding cart slides along the conveying slide rail to a position flush with the loading mechanism, and the control system issues an instruction to start the movement of the feeding mechanism. The clamping assemblies of the manipulator precisely clamp both ends of the reel of the external roll. The feeding mechanism continues to move in the direction away from the loading mechanism, so that the external roll is separated from the feeding cart and clamped by the manipulator to complete the loading. Through the above design and working process, the unwinding automatic loading machine of the utility model realizes the automatic, efficient, and precise loading of the external roll in the production of lithium batteries, improves the production efficiency, and reduces the manual labor intensity.

[0006] The feeding mechanism includes a conveying slide rail and a feeding trolley slidably arranged on the conveying slide rail. The feeding trolley includes a mobile base, a fixed frame arranged on the mobile base and multiple groups of first rod bodies. One end of the first rod body is fixedly arranged on the fixed frame, and the external coil passes through the first rod body and the other end away from the fixed frame is sleeved on the first rod body.

[0007] The smooth and stable transportation of external coils is achieved through the sliding cooperation of the conveyor slide rail and the feeding trolley. This helps to reduce the vibration and impact of the coils during movement and protect the coils from damage. The design of the feeding trolley enables the external coils to be accurately delivered to a position flush with the feeding mechanism, providing good conditions for the manipulator to clamp the coils. This helps to improve feeding accuracy and efficiency. The automated design of the feeding mechanism reduces the need for manual intervention, reducing the difficulty of operation and labor intensity. Workers only need to place the coils on the feeding trolley and start the equipment to complete the feeding process.

[0008] The frame also includes multiple sets of limit wheels arranged on the frame, and the multiple sets of limit wheels are arranged along the moving direction of the feeding cart. The limit wheels are used to contact the feeding cart to prevent the feeding cart from shifting during movement. Multiple sets of limit wheels are arranged on the frame along the moving direction of the feeding cart. The main purpose is to provide additional support and guidance during the sliding process of the feeding cart, to ensure that the feeding cart can move smoothly along the predetermined path, and prevent it from shifting or deviating from the track. The limit wheels contact parts such as the moving base or side panels of the feeding cart, and limit the moving trajectory of the feeding cart through physical resistance. By limiting the moving trajectory of the feeding cart, the limit wheels help ensure that the feeding cart can accurately reach a position flush with the feeding mechanism. This is crucial to improving feeding accuracy and efficiency, because any slight deviation may cause the robot to fail to properly clamp the coil.

[0009] The feeding mechanism includes a first slide rail, a second slide rail, a third slide rail and a support frame arranged on the frame, the first slide rail is arranged in parallel with the second slide rail, the two ends of the support frame are respectively arranged vertically on the first slide rail and the second slide rail, the third slide rail is arranged on the support frame along the length direction of the support frame, the manipulator is slidably arranged on the third slide rail, the manipulator is driven by a driving motor to move left and right along the length direction of the third slide rail and move forward and backward along the length direction of the first slide rail and the second slide rail to adjust the feeding position. The feeding mechanism also includes an up-and-down moving guide rail, the up-and-down moving guide rail is slidably arranged on the third slide rail, and the manipulator can move up and down to adjust the feeding position via the up-and-down moving guide rail.

[0010] The feeding mechanism realizes the free movement of the manipulator in three-dimensional space through the combination design of three slide rails (first slide rail, second slide rail and third slide rail) and upper and lower movable guide rails. This design enables the manipulator to flexibly adjust the feeding position. The full range of adjustment capabilities enables the feeding mechanism to cope with more diverse production scenarios and external coil specifications, enhancing the flexibility and adaptability of the equipment.

[0011] The manipulator includes a first support and two sets of clamping components respectively arranged at both ends of the first support. A gripper is provided at one end of the clamping component away from the first support, and the gripper is used to grab the reels protruding from both ends of the external coil material, so that the external coil material is separated from the feeding mechanism to complete the loading. The design of the gripper is specifically for grabbing the reels protruding from both ends of the external coil material. This design ensures that the manipulator can accurately position and grab the coil material, avoiding damage or deformation that may be caused by directly clamping the coil material body. At the same time, by grabbing the reels, the manipulator can more stably control the movement of the coil material and reduce the shaking during the transmission process.

[0012] The double-sided tape laminating roller is arranged above the manipulator and the winding component. The external coil material placed on the manipulator is laminated by the double-sided tape laminating roller and then wound onto the winding component. The external coil material can be a film material for lithium batteries. The manipulator first grabs the external coil material (specifically referring to the film material for lithium batteries) placed at the designated position. Subsequently, the film material is conveyed under the double-sided tape laminating roller, and through the rotation of the roller and the contact with the material, the uniform coating of the double-sided tape is realized. Finally, the film material after the laminating treatment is sent to the winding component for winding.

[0013] The winding component includes a winding frame body and a winding slide rail. The winding frame body includes a first column, a second column, and a telescopic winding roller connecting the first column and the second column. The first column is slidably arranged on the winding slide rail, and the telescopic winding roller realizes telescoping through the reciprocating sliding of the first column to adapt to external coil materials of different lengths. The telescopic winding roller is the core component of the winding component, and it can realize telescoping through the reciprocating sliding of the first column on the winding slide rail. This design allows the winding roller to be dynamically adjusted according to the actual length of the external coil material, ensuring that the coil material can be wound tightly and evenly on the roller. The design of the telescopic winding roller enables the winding component to easily handle external coil materials of different lengths. Whether it is a short test sample or an industrial-grade coil material several meters long, the stable and efficient winding can be achieved by adjusting the length of the winding roller.

[0014] The telescopic winding roller can be a sponge winding roller. If the film material has a certain hydrophilicity, it can adhere to the sponge more easily after getting wet. This characteristic helps to maintain the stability of the film material during the winding process.

[0015] Both ends of the first slide rail, the second slide rail, the third slide rail, and the up-and-down moving guide rail are provided with anti-collision parts, and the anti-collision parts are used to prevent the manipulator from hitting the guide rail system during reciprocating movement. By absorbing the impact energy and dispersing the impact force, the anti-collision parts can effectively protect the manipulator and the guide rail system from serious damage. This helps to extend the service life of the equipment and reduce the production delay and cost increase caused by equipment failures.

[0016] A plurality of positioning sensors are also provided at the bottom of the frame. The positioning sensors are arranged along the moving direction of the feeding mechanism. When the feeding mechanism moves to the feeding position, the positioning sensors send signals to the control system to trigger the manipulator to clamp the external coil material. Through the precise positioning and triggering mechanism, it can ensure that the manipulator performs the clamping action at the correct time and position, thus avoiding production delays and waste caused by inaccurate positions, which helps to improve the overall efficiency of the production line.

[0017] Advantages of the utility model: The utility model realizes the full-automatic processing of the laminating material in the production of lithium batteries through the feeding mechanism, the feeding mechanism, the double-sided tape gluing roller and the winding assembly. When the feeding mechanism moves to a position flush with the feeding mechanism, the clamping assembly of the feeding mechanism clamps both ends of the reel of the external coil material placed on the feeding mechanism, and the feeding mechanism moves towards one end away from the feeding mechanism, and the external coil material on the feeding mechanism is separated from the feeding mechanism to complete the feeding. The external laminating material is conveyed under the double-sided tape gluing roller, and through the rotation of the roller and the contact with the material, the uniform coating of the double-sided tape is realized. Finally, the laminated material after the gluing treatment is sent to the winding assembly for winding, which not only greatly improves the production efficiency, but also significantly reduces the complexity and labor intensity of manual operation.

Detailed Embodiments

[0024] For the convenience of those skilled in the art, the present utility model will be further described below in conjunction with embodiments and the accompanying drawings. The content mentioned in the embodiments does not limit the present utility model.

[0025] Please refer to Figures 1 to 4 As shown, an unwinding automatic loading machine for lithium battery production of the present utility model includes a frame 1, a loading mechanism 2, a feeding mechanism 3, a double-sided tape laminating roller 4, and a winding assembly 5 provided on the frame 1; the feeding mechanism 3 is slidably arranged on the frame 1, and the feeding mechanism 3 is arranged in parallel with the loading mechanism 2, the double-sided tape laminating roller 4, and the winding assembly 5. The loading mechanism 2 includes a manipulator 6, and the manipulator 6 is slidably arranged on the frame 1. Clamping assemblies 7 are provided at both ends of the manipulator 6. When the feeding mechanism 3 moves to a position flush with the loading mechanism 2, the clamping assemblies 7 of the loading mechanism 2 clamp both ends of the reel of the external coil placed on the feeding mechanism 3. The feeding mechanism 3 moves away from the loading mechanism 2, and the external coil on the feeding mechanism 3 is separated from the feeding mechanism 3 to complete the loading.

[0026] The external coil is placed on the feeding cart 9 of the feeding mechanism 3 and fixed by a fixing frame 12 and a rod body. The feeding cart 9 slides along the conveying slide rail 8 to a position flush with the loading mechanism 2, and the control system issues an instruction to start the movement of the feeding mechanism 3. The clamping assemblies 7 of the manipulator 6 precisely clamp both ends of the reel of the external coil. The feeding mechanism 3 continues to move away from the loading mechanism 2, so that the external coil is separated from the feeding cart 9 and clamped by the manipulator 6 to complete the loading. Through the above design and working process, the unwinding automatic loading machine of the present utility model realizes the automatic, efficient, and precise loading of the external coil in lithium battery production, improves the production efficiency, and reduces the labor intensity of workers.

[0027] The feeding mechanism 3 includes a conveying slide rail 8 and a feeding cart 9 slidably arranged on the conveying slide rail 8. The feeding cart 9 includes a moving base 11, a fixing frame 12 provided on the moving base 11, and multiple groups of first rod bodies 13. One end of the first rod body 13 is fixedly arranged on the fixing frame 12, and the external coil passes through the other end of the first rod body 13 away from the fixing frame 12 and is sleeved on the first rod body 13.

[0028] Through the sliding cooperation of the conveying slide rail 8 and the feeding cart 9, the stable and steady transportation of the external coil is realized. This helps to reduce the vibration and impact of the coil during movement and protects the coil from damage. The design of the feeding cart 9 enables the external coil to be accurately delivered to a position flush with the loading mechanism 2, providing good conditions for the manipulator 6 to clamp the coil. This helps to improve the loading accuracy and efficiency. The automated design of the feeding mechanism 3 reduces the need for manual intervention, reduces the operation difficulty and labor intensity. Workers only need to place the coil on the feeding cart 9 and start the equipment to complete the feeding process.

[0029] The rack 1 further includes multiple groups of limiting wheels 14 provided on the rack 1. The multiple groups of limiting wheels 14 are arranged along the moving direction of the feeding cart 9. The limiting wheels 14 are used to abut against the feeding cart 9 to prevent it from shifting during movement. The multiple groups of limiting wheels 14 are arranged on the rack 1 along the moving direction of the feeding cart 9. The main purpose is to provide additional support and guidance during the sliding process of the feeding cart 9, ensuring that the feeding cart 9 can move smoothly along the predetermined path and preventing it from shifting or deviating from the track. The limiting wheels 14 contact parts such as the moving base 11 or the side plate of the feeding cart 9, and limit the moving trajectory of the feeding cart 9 through physical abutment. By restricting the moving trajectory of the feeding cart 9, the limiting wheels 14 help ensure that the feeding cart 9 can accurately reach the position flush with the feeding mechanism 2. This is crucial for improving the feeding accuracy and efficiency, because any slight deviation may cause the manipulator 6 to be unable to correctly grip the coil material.

[0030] The feeding mechanism 2 includes a first slide rail 15, a second slide rail 16, a third slide rail 17 and a support frame 18 provided on the rack 1.

The third slide rail 17 is arranged on the support frame 18 along the length direction of the support frame 18. The manipulator 6 is slidably arranged on the third slide rail 17. The manipulator 6 is driven by a driving motor to move left and right along the length direction of the third slide rail 17 and move forward and backward along the length direction of the first slide rail 15 and the second slide rail 16 to adjust the feeding position. The feeding mechanism 2 further includes an up-and-down moving guide rail 19. The up-and-down moving guide rail 19 is slidably arranged on the third slide rail 17. The manipulator 6 can move up and down through the up-and-down moving guide rail 19 to adjust the feeding position.

[0031] Through the combined design of three slide rails (the first slide rail 15, the second slide rail 16 and the third slide rail 17) and the up-and-down moving guide rail 19, the feeding mechanism 2 realizes the free movement of the manipulator 6 in three-dimensional space. This design enables the manipulator 6 to flexibly adjust the feeding position. The all-round adjustment ability enables the feeding mechanism 2 to cope with more diverse production scenarios and external coil material specifications, enhancing the flexibility and adaptability of the equipment.

[0032] The manipulator 6 includes a first bracket 21 and two groups of clamping assemblies 7 respectively arranged at both ends of the first bracket 21. A gripper is provided at one end of the clamping assembly 7 away from the first bracket 21. The gripper is used to grab the reels protruding from both ends of the external coil material to separate the external coil material from the feeding mechanism 3 and complete the feeding. The design of the gripper is specifically for grabbing the reels protruding from both ends of the external coil material. This design ensures that the manipulator 6 can accurately position and grab the coil material, avoiding damage or deformation that may be caused by directly clamping the coil material body. At the same time, by grabbing the reels, the manipulator 6 can more stably control the movement of the coil material and reduce the shaking during the transmission process.

[0033] The double-sided tape laminating roller 4 is arranged above the manipulator 6 and the winding assembly 5. The external coil material placed on the manipulator 6 is laminated by the double-sided tape laminating roller 4 and then wound onto the winding assembly 5.

Subsequently, the laminating material is conveyed below the double-sided tape laminating roller 4, and through the rotation of the roller and contact with the material, uniform coating of the double-sided tape is achieved. Finally, the laminated material after the laminating process is sent to the winding assembly 5 for winding.

[0034] The winding assembly 5 includes a winding frame body 23 and a winding slide rail 24.
