Description

Technical Field

[0001] This utility model belongs to the field of automated production technology, and more specifically, it relates to an automatic adhesive applicator for empty material cylinders. Background Technology

[0002] In the electrode production process, the adhesive application process on empty coils of conventional rolled electrodes is crucial. Currently, this process is typically done manually. Specifically, operators manually apply single-sided adhesive tape to the empty coil before placing it at the winding station for electrode winding. However, this traditional manual method has significant drawbacks: after unwinding, tape residue often remains on the coil. This residue is difficult to clean and negatively impacts subsequent production efficiency and product quality. Currently, to address this issue, a reverse application method is commonly used, where the tape is applied backwards onto the electrode before being attached to the coil. However, this process is cumbersome and requires manual cleaning of residue and application, increasing labor intensity and production costs.

[0003] Therefore, there is an urgent need for a device that can automatically apply single-sided tape to empty material cylinders to replace traditional manual operation, improve production efficiency, reduce the difficulty of cleaning residual adhesive, and reduce the need for manual intervention.

[0046] Please refer to the following: Figures 1 to 3 The automatic adhesive applicator for empty material cylinders 8 provided by this utility model will now be described. The automatic adhesive applicator for empty material cylinders 8 includes a frame 1, a sliding assembly 2, a fixing assembly 3, a clamping assembly 4, an adhesive applicator 6, and a cutting assembly 5. The frame 1 has a through groove for accommodating the material cylinder 8, and an annular slide rail is provided on the frame 1, the slide rail being located around the through groove. The sliding assembly 2 includes a guide rail 201 slidably connected to the slide rail and a drive mechanism 202 fixed to the frame 1. The drive end of the drive mechanism 202 is connected to the frame 1 and is used to drive the guide rail 201 to move along the slide rail. The fixing assembly 3 includes a fixing bracket 301 connected to the guide rail 201 and a fixing bracket 301 connected to the fixing bracket 5. The tensioning mechanism 302 of the frame 301 is used to fix the tape roll 7 and to tension the unwinding section of the tape roll 7. The clamping assembly 4 includes a gripper mechanism 401 and a pressure roller mechanism 402 fixed to the frame 1. The gripper mechanism 401 is used to clamp the unwinding section of the tape roll 7 and the pressure roller mechanism 402 is used to make the unwinding section of the tape abut against the outer wall of the barrel 8. The bonding assembly 6 is connected to the frame 1 and is used to bond the tape wrapped around the outer circumference of the barrel 8. The cutting assembly 5 is connected to the frame 1 and is used to cut the unwinding end of the tape roll 7.

[0047] The automatic tape applicator for empty material cylinder 8 provided by this utility model, compared with the prior art, achieves automatic unwinding, tensioning, bonding, pasting, and cutting of tape through automated design, completely replacing the traditional manual tape application operation, significantly improving production efficiency, reducing the need for manual intervention, and lowering labor intensity and production costs. The sliding component 2 and the fixing component 3 work together to ensure that the tape is evenly distributed and appropriately tensioned during the application process, avoiding tape slack or deviation, and improving the accuracy and consistency of tape application. Furthermore, the design of the gripper mechanism 401 and the pressure roller mechanism 402 ensures that the tape is tightly bonded to the outer wall of the material cylinder 8, further enhancing the adhesion and reducing the possibility of tape detachment. The combined use of the pasting component 6 and the cutting component 5 ensures the firm connection of the tape ends and the accuracy of the tape length, avoiding the problems of tape waste and residual adhesive cleaning. This utility model not only improves the automation level of the tape application process but also significantly improves production efficiency and product quality, and has broad application prospects and economic benefits.

[0048] Work process:

[0049] Insert the material cylinder 8 into the through slot, and install the tape roll 7 on the fixing frame 301. The unwinding section of the tape roll 7 passes around the tensioning mechanism 302, and the gripper mechanism 401 extends and clamps the unwinding section of the tape roll 7. Subsequently, the gripper mechanism 401 rotates, causing the tape to be stretched during rotation, and the tensioning mechanism 302 tensions the tape, ensuring that the tape remains flat and taut in subsequent operations. After the tape is tensioned, the pressure roller mechanism 402 extends and presses down, pressing the starting end of the tape roll 7 against the outer wall of the material cylinder 8, ensuring that the tape is tightly adhered to the material cylinder 8. After pressing, the gripper mechanism 401 releases the tape and retracts, while rotating back to the initial position, preparing for the next operation. After the tape is fixed, the drive mechanism 202 drives the guide rail 201 to rotate clockwise one revolution along the annular slide, so that the tape is evenly wrapped around the outer circumference of the material cylinder 8. After the guide rail 201 rotates one revolution, the adhesive bonding component 6 presses down, pressing the overlapping portion of the tape end and the starting end together to ensure a firm connection between the tape ends, forming a complete ring-shaped adhesive bonding structure. After bonding, the cutting component 5 cuts off the unwinding end of the tape, ensuring accurate tape length and avoiding waste. After cutting, the cutting component 5 resets. Finally, the material cylinder 8 rotates counterclockwise and re-attaches with the adhesive bonding component 6, pressing and bonding the remaining tape portion after cutting to ensure the tape is completely fixed and prevents loosening or falling off. Through the above steps, this device achieves fully automated operation from tape clamping, tensioning, winding, bonding to cutting, significantly improving bonding efficiency and quality, reducing manual intervention and the difficulty of residual adhesive cleaning, and is suitable for the bonding process of empty material cylinder 8 in electrode production.

[0050] Optionally, the frame 1 has an opening that connects radially to the through groove, through which the material cylinder 8 enters and exits the through groove, making it more convenient to load and unload the material cylinder 8.

[0051] In some embodiments, please refer to Figures 1 to 3 The guide rail 201 is an arc-shaped or annular component, and the outer wall of the guide rail 201 is provided with driving teeth. The driving mechanism 202 includes a sliding driver 2021 and a transmission gear 2022. The sliding driver 2021 is mounted on the frame 1. The transmission gear 2022 is connected to the driving end of the sliding driver 2021 and meshes with the driving teeth. The sliding driver 2021 is used to drive the transmission gear 2022 to rotate around its own axis.

[0052] The arc or ring structure of the guide rail 201 allows it to perfectly match the slide rail on the frame 1, ensuring the sliding component 2 remains stable during movement, reducing vibration and offset, and thus improving the accuracy of adhesive application. The meshing transmission method between the drive teeth on the outer wall of the guide rail 201 and the transmission gear 2022 not only achieves high efficiency and reliability in power transmission but also precisely controls the moving speed and position of the guide rail 201, meeting the adhesive application requirements of different sized cartridges 8. The reasonable installation position of the sliding actuator 2021, by driving the transmission gear 2022 to rotate around its own axis, further optimizes the stability and continuity of power output. This design not only reduces the operating noise and maintenance costs of the equipment but also extends its service life. This embodiment, through the innovative design of the guide rail 201 and drive mechanism 202, significantly improves the automation level, adhesive application accuracy, and production efficiency of the device, making it suitable for high-precision, high-requirement industrial production environments.

[0053] Optionally, the slide driver 2021 is a motor.

The driving end of the rotating drive 4012 rotates about the first path as the axis of rotation. The clamp 4011 is connected to the rotating drive 4012 or the moving drive 4013, and the clamp 4011 is used to clamp the unwinding section of the tape roll 7.

[0055] The gripper mechanism 401 employs a combination design of a moving drive 4013 and a rotary drive 4012. The moving drive 4013 extends and retracts along a first path parallel to the through-slot path, ensuring that the gripper 4011 can accurately approach or move away from the material cylinder 8, thus adapting to the placement requirements of material cylinders 8 and tape rolls 7 of different sizes. The introduction of the rotary drive 4012 allows the gripper 4011 to rotate around the first path as its axis, further enhancing the multi-angle adjustment capability of the gripper mechanism 401 and ensuring that the unwinding section of the tape roll 7 can be gripped and positioned at the optimal angle. The gripper 4011 is directly connected to the rotary drive 4012 or the moving drive 4013, featuring a compact structure and rapid response, enabling quick and secure gripping of the tape and preventing tape shifting or loosening during application. This design not only improves the accuracy and consistency of application but also significantly reduces the need for manual intervention, increasing production efficiency. Furthermore, the high flexibility and high precision of the gripper mechanism 401 allow it to adapt to complex application tasks and meet diverse production needs.

The pressure driver 4022 controls the pressure roller 4021 to switch between a pressing state and a separating state. In the pressing state, the pressure roller 4021 presses the unwinding section of the tape roll 7 against the outer wall of the barrel 8. In the separating state, the pressure roller 4021 separates from the unwinding section of the tape roll 7.

[0060] The pressure roller mechanism 402 consists of a pressure driver 4022 and a pressure roller 4021. The pressure driver 4022 is connected to the frame 1 and can precisely control the pressure roller 4021 to switch between the pressing and unpressing states. In the pressing state, the pressure roller 4021 tightly presses the unwinding section of the tape roll 7 against the outer wall of the barrel 8, ensuring full contact between the tape and the surface of the barrel 8, avoiding the generation of air bubbles or wrinkles, thereby improving the adhesion and aesthetics of the adhesive. In the unpressing state, the pressure roller 4021 separates from the unwinding section of the tape roll 7, facilitating tape adjustment or replacement, further enhancing operational flexibility and convenience. The precise control function of the pressure driver 4022 makes the pressure of the pressure roller 4021 adjustable, adapting to tapes of different materials and thicknesses, ensuring consistency and reliability in the adhesive application process. In addition, the pressure roller mechanism 402 has a simple structure and is easy to maintain, reducing the operating cost and ease of use of the equipment.

[0066] The adhesive assembly 6 consists of an adhesive driver 603 and an adhesive piece. The adhesive driver 603 is connected to the frame 1 and can precisely control the switching of the adhesive piece between the adhesive and standby states. In the adhesive state, the adhesive piece abuts against the unwinding section of the tape roll 7, ensuring that the beginning and end of the tape are quickly and firmly bonded. This avoids problems such as weak adhesion or positional deviation that may occur in traditional manual operations, thereby improving the quality and consistency of adhesive application. In the standby state, the adhesive piece separates from the unwinding section of the tape roll 7, facilitating tape adjustment or replacement and further enhancing operational flexibility and convenience.

[0069] The adhesive applicator consists of a support member 601 and a roller 602. The support member 601 is connected to the adhesive driver 603, accurately transmitting the driver's power. The roller 602 is rotatably connected to the support member 601 around a first axis parallel to the axis of the slide, ensuring that the movement direction of the roller 602 is consistent with the axes of the slide and the material cylinder 8. This design allows the roller 602 to roll evenly and smoothly during the adhesive application process, avoiding problems such as tape misalignment, wrinkling, or air bubbles, thereby improving the adhesion and aesthetics of the adhesive.

Simultaneously, the buffering effect of the elastic element 6013 allows the roller 602 to adapt to different sizes of cartridges 8 and tapes, ensuring uniform pressure distribution during the adhesive application process, further improving the adhesion and consistency of the adhesive. Furthermore, the modular design of the support component 601 simplifies the equipment structure, facilitates installation, maintenance, and replacement, and reduces the operating costs and ease of use of the equipment.

[0072] Optionally, the elastic element 6013 is a spring.

[0073] In some embodiments, please refer to Figures 1 to 3 The tensioning mechanism 302 includes multiple tensioning rollers spaced apart and parallel to each other. The multiple tensioning rollers are used to tension the unwinding section of the tape roll 7.

[0074] The tensioning mechanism 302 employs multiple spaced and parallel tension rollers. These rollers evenly distribute the tension across the unwinding section of the tape roll 7, preventing issues such as slackness, misalignment, or twisting of the tape during unwinding. The synergistic effect of the multiple tension rollers ensures that the tape remains taut throughout the entire application process, thereby improving the smoothness and consistency of the application and reducing defects such as bubbles and wrinkles.
