Description

Technical Field

[0001] This utility model relates to the field of film removal equipment technology, and in particular to a film removal device for the surface insulating film of a square aluminum-cased battery. Background Technology

[0002] Square aluminum-cased batteries, as a key component widely used in the new energy field, are typically covered with an insulating film. This insulating film mainly serves to provide electrical insulation, prevent short circuits between battery casings, and provide a certain degree of mechanical protection, making it an important component for ensuring the safe use of batteries. However, during battery production or testing, some products inevitably need to be reworked due to damaged, dirty, or other defects in the insulating film. For these batteries requiring rework, the original insulating film must be completely removed and thoroughly cleaned before a new insulating film can be applied to ensure the quality and safety performance of the final product. Therefore, efficiently and thoroughly removing the insulating film from the surface of square aluminum-cased batteries is a crucial and essential step in the battery rework process.

[0003] Currently, the main method of handling this issue is manual operation. The process typically involves the operator first attempting to manually peel off the insulating film. However, because the untreated insulating film adheres very firmly to the surface of the battery's aluminum casing, direct removal is not only laborious, time-consuming, and inefficient, but also easily leaves a large amount of granular or blocky adhesive residue on the battery surface. Batteries with adhesive residue cannot be directly re-coated and must undergo subsequent cleaning steps. Operators need to use solvents such as alcohol to wipe away large pieces of adhesive residue, and finally, manual polishing with sandpaper or abrasive wool is required to completely remove the firmly adhered fine adhesive residue. The entire process is highly dependent on manual labor, labor-intensive, cumbersome, and slow. With the rapid expansion of production capacity in the new energy industry, the number of square aluminum-cased batteries requiring rework has surged. The traditional manual film peeling and adhesive removal process not only consumes a large amount of labor costs, but its efficiency is also far behind the rate at which defective products are produced by equipment, resulting in a large backlog of batteries awaiting rework in warehouses. Even more serious is that the insulating film of batteries stored for a long time will further solidify and bond more tightly with the battery casing, making it more difficult and time-consuming to remove the film manually, and the problem of residual adhesive will become more prominent, creating a vicious cycle.

[0004] Therefore, there is an urgent need to design a device for removing the insulating film from the surface of square aluminum-cased batteries to solve the problems of severe adhesive residue and low overall efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a device for removing the insulating film from the surface of a square aluminum-cased battery, which solves the problems of serious residual adhesive and low overall efficiency in existing manual film removal methods.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A device for removing the insulating film from the surface of a square aluminum-cased battery includes a frame, and a clamping mechanism, a carrier mechanism, and a laser film removal mechanism mounted on the frame. The clamping mechanism has a pair of clamping blocks, which are driven by a first linear drive source to move towards or away from each other to clamp or release the battery. The pair of clamping blocks are also driven by a rotary drive source to rotate around the line connecting the centers of the two clamping blocks. The carrier mechanism includes a battery carrier and a first drive assembly, which drives the battery carrier to move closer to or away from the battery located on the clamping mechanism. The laser film removal mechanism includes a laser head, which faces the battery located on the clamping mechanism during operation.

[0008] Furthermore, it also includes a control cabinet, which is connected to the first linear drive source, the rotary drive source, the first drive assembly, and the laser head signal.

[0009] Furthermore, the laser film removal mechanism also includes a second driving component, which is used to drive the laser head to approach or move away from the battery located on the clamping mechanism, and the second driving component is signal-connected to the control cabinet.

[0010] Furthermore, the first drive component includes a first X-axis linear module, a Y-axis linear module, and a first Z-axis linear module, which are used to drive the battery carrier to move along the X-axis, Y-axis, and Z-axis, respectively.

[0011] Furthermore, the Y-axis linear module includes a Y-axis guide rail fixed on the frame, a Y-axis slider slidably mounted on the Y-axis guide rail, and a second linear drive source for driving the Y-axis slider to move on the Y-axis guide rail.

[0012] The first X-axis linear module includes a first X-axis guide rail fixed on the Y-axis slider, a first X-axis slider slidably mounted on the first X-axis guide rail, and a third linear drive source that drives the first X-axis slider to move on the first X-axis guide rail.

[0013] The first Z-axis linear module includes a first Z-axis slide rail fixed to the first X-axis slider, a first Z-axis slide table that moves up and down along the first Z-axis slide rail, and a fourth linear drive source that drives the first Z-axis slide table to move up and down.

[0014] The battery carrier is fixed on the first Z-axis slide;

[0015] The second, third, and fourth linear drive sources are connected to the control cabinet signal.

[0016] Furthermore, the second driving component includes a second X-axis linear module and a second Z-axis linear module, which are used to drive the laser head to move along the X-axis and Z-axis, respectively;

[0017] The laser head and the battery located on the clamping mechanism are in the same XZ plane.

[0018] Furthermore, the second X-axis linear module includes a second X-axis guide rail fixed on the frame, a second X-axis slider slidably mounted on the second X-axis guide rail, and a fifth linear drive source for driving the second X-axis slider to move on the second X-axis guide rail;

[0019] The second Z-axis linear module includes a second Z-axis slide rail fixed to the second X-axis slider, a second Z-axis slide table that moves up and down along the second Z-axis slide rail, and a sixth linear drive source that drives the second Z-axis slide table to move up and down.

[0020] The laser head is fixed on the second Z-axis slide;

[0021] The fifth and sixth linear drive sources are connected to the control cabinet via signal transmission.

[0022] Furthermore, the battery carrier is equipped with a sensor for detecting whether a battery is placed on it, and the sensor is connected to the control cabinet via a signal connection.

[0023] Furthermore, the battery carrier is provided with at least one limiting surface that abuts against the battery.

[0024] Furthermore, the frame is equipped with two sets of clamping mechanisms and carrier mechanisms.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] When using the square aluminum-shell battery surface insulating film removal device described in this invention to remove the insulating film from the surface of a square aluminum-shell battery, the laser film removal mechanism directly acts on the insulating film on the battery surface. Laser pretreatment significantly reduces the adhesion between the insulating film and the battery casing, making subsequent film removal operations extremely easy and greatly improving the film removal efficiency. This effectively avoids the problem of large amounts of granular residue generated by traditional film removal methods. Furthermore, the rotation function of the clamping mechanism enables continuous and automated laser film removal processing on multiple sides of the square battery. The coordinated action of the carrier mechanism and the clamping mechanism ensures accurate positioning and stable clamping of the battery at the clamping station, as well as timely avoidance and safe removal and placement of the carrier after processing.

[0027] This invention also includes a control cabinet. By coordinating the sequence, timing, and position parameters of actions in each stage—including the transfer and positioning of the carrier mechanism, the clamping, loosening, and rotation of the clamping mechanism, and the laser emission of the laser film removal mechanism—the control cabinet achieves automated operation of the entire film removal process, significantly reducing manual intervention and improving processing speed and consistency. Furthermore, sensors are installed on the battery carrier to detect whether batteries are placed on it. Only when the sensors confirm that the batteries are correctly placed on the carrier will the control cabinet initiate subsequent transfer and processing steps. This avoids ineffective equipment operation, positioning errors, and even collision risks caused by no-load or improper placement, ensuring the reliability and safety of the processing. Simultaneously, this also provides basic signals for cycle time control and process management of the automated production line. Attached Figure Description

[0041] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0042] This embodiment provides a device for removing the insulating film from the surface of square aluminum-cased batteries. It efficiently processes square aluminum-cased batteries by using laser pretreatment to significantly reduce the adhesion of the insulating film, facilitating subsequent manual or mechanical film removal and reducing residual adhesive, thereby improving overall film removal efficiency. Combined with... Figure 1As shown, the square aluminum-cased battery surface insulating film removal device includes a frame 1, and a carrier mechanism 3, a clamping mechanism 2, a laser film removal mechanism 4, and a control cabinet 5 mounted on the frame 1. In this embodiment, the carrier mechanism 3 is used to carry the battery to be processed and transport it to the clamping station and remove it from the clamping station. The clamping mechanism 2 is used to firmly clamp the battery and drive it to rotate so that different processing surfaces are sequentially aligned with the laser head 41. The laser film removal mechanism 4 is used to emit a laser beam to scan the insulating film on the battery surface. The laser beam acts on the adhesive layer between the insulating film and the battery casing, and through the thermal effect of the laser, it breaks or modifies the adhesive molecular chains, thereby significantly weakening its adhesion performance, making the insulating film easy to peel off and less likely to produce large pieces of residual adhesive. Figure 2As shown, the clamping mechanism 2 is equipped with a pair of clamping blocks 21. The pair of clamping blocks 21 are driven by the first linear drive source 22 to move towards or away from each other to clamp or release the battery, ensuring that the battery is fixed in position during processing. A clamping station is formed in the middle of the pair of clamping blocks 21. The pair of clamping blocks 21 are driven by the rotary drive source 23 to rotate around the straight line connecting the centers of the two clamping blocks 21, so that the battery rotates around its central axis, thereby rotating the four sides of the battery sequentially to face the laser head 41 for film removal processing. The carrier machine Structure 3 includes a battery carrier 31 and a first driving component. The first driving component is used to drive the battery carrier 31 to move closer to or away from the battery located on the clamping mechanism 2, so as to realize the smooth transfer of the battery between the initial position of the battery carrier 31 and the clamping station, the timely avoidance of the battery carrier 31 after clamping, and the unloading of the battery after processing. The laser film removal mechanism 4 includes a laser head 41. When working, the laser head 41 is facing the battery located on the clamping mechanism 2 to ensure that the laser beam can act directly on the surface of the battery to be processed. The laser film removal mechanism 4 also includes a second driving component. The second driving component is used to drive the laser head 41 to move closer to or away from the battery located on the clamping mechanism 2. On the one hand, when the battery rotates to switch processing surfaces, the laser head 41 can be driven to move to avoid interference with the rotating clamping mechanism 2 or the battery, so as to ensure operational safety. On the other hand, by adjusting the position of the laser head 41 relative to the battery surface, it can adapt to the processing requirements of batteries of different sizes (such as height and width), so as to ensure that the laser beam can always act effectively and uniformly on the target area. The control cabinet 5 is signal-connected to the first linear drive source 22, the rotary drive source 23, the first drive assembly, the laser head 41, and the second drive assembly, coordinating and controlling the sequence, speed, and position of each mechanism's actions to achieve automated operation of the entire film removal process. In this embodiment, the control cabinet 5 is equipped with operation buttons and / or an operation screen for operators to start / stop equipment operation or perform basic control operations such as emergency stop, providing an intuitive and convenient human-machine interface. The operation screen can also display the equipment's operating status in real time (such as the current processing step, battery position information, and laser head status), key parameters (such as laser power settings and rotation angle settings), and provide a graphical interface for operators to perform more complex parameter settings (such as processing parameters for different battery models), realizing comprehensive visual monitoring and advanced control of the equipment's operating status. In this embodiment, the frame 1 is provided with two sets of clamping mechanisms 2 and carrier mechanisms 3. One set of laser film removal mechanism 4 works in conjunction with the two sets of clamping mechanisms 2 and carrier mechanisms 3. Since the carrier mechanism 3 and clamping mechanism 2 will have waiting intervals during loading, clamping, unloading and other operations, the other set of clamping mechanisms 2 and carrier mechanisms 3 can perform loading or unloading operations when one set is in the processing state (i.e., the laser film removal mechanism 4 is occupied), effectively staggering the operation gap period, maximizing the utilization rate of the laser film removal mechanism 4, and significantly improving the overall efficiency of the device.

[0043] Combination Figure 3 As shown, the first driving component includes a first X-axis linear module 32, a Y-axis linear module 33, and a first Z-axis linear module 34, which are used to drive the battery carrier 31 to move along the X, Y, and Z axes, respectively, to realize the positioning and motion trajectory control of the battery carrier 31 in three-dimensional space, to ensure that the battery is accurately transferred to the clamping position and safely descends to avoid obstacles after clamping. Specifically, in this embodiment, the Y-axis linear module 33 includes a Y-axis guide rail 331 fixed on the frame 1, a Y-axis slider 332 slidably mounted on the Y-axis guide rail 331, and a second linear drive source 333 that drives the Y-axis slider 332 to move on the Y-axis guide rail 331. The Y-axis linear module 33 is responsible for the movement of the battery carrier 31 along the front-rear direction (Y-axis) of the device. The first X-axis linear module 32 includes a first X-axis guide rail 321 fixed on the Y-axis slider 332, a first X-axis slider 322 slidably mounted on the first X-axis guide rail 321, and a third linear drive source 333 that drives the first X-axis slider 322 to move on the first X-axis guide rail 321. The power source 323 and the first X-axis linear module 32 are responsible for positioning the battery carrier 31 along the left-right direction (X-axis) of the equipment to ensure alignment with the clamping mechanism 2. The first Z-axis linear module 34 includes a first Z-axis slide rail 341 fixed to the first X-axis slider 322, a first Z-axis slide table 342 that moves up and down along the first Z-axis slide rail 341, and a fourth linear drive source 343 that drives the first Z-axis slide table 342 to move up and down. The battery carrier 31 is fixed on the first Z-axis slide table 342. The first Z-axis linear module 34 is responsible for the up-down direction (Z-axis) of the battery carrier 31 to achieve the lifting of the battery to the clamping height and the lowering and avoidance after processing. The second linear drive source 333, the third linear drive source 323, and the fourth linear drive source 343 are connected to the control cabinet 5 by signals, receive instructions from the control cabinet 5, and work together to complete the three-dimensional positioning and transfer of the battery carrier 31.

[0044] Combination Figure 4As shown, the second driving assembly includes a second X-axis linear module 42 and a second Z-axis linear module 43, which are used to drive the laser head 41 to move along the X and Z axes, respectively, to adjust the working position of the laser head 41. The laser head 41 and the battery located on the clamping mechanism 2 are on the same XZ plane, ensuring that the laser beam can always be perpendicular to the surface of the battery to be processed for scanning. Specifically, in this embodiment, the second X-axis linear module 42 includes a second X-axis guide rail 421 fixed on the frame 1, a second X-axis slider 422 slidably mounted on the second X-axis guide rail 421, and a fifth linear drive source 423 that drives the second X-axis slider 422 to move on the second X-axis guide rail 421. The second X-axis linear module 42 is used to fine-tune the position of the laser head 41 in the X direction. The second Z-axis linear module 43 includes a second Z-axis slide rail 431 fixed on the second X-axis slider 422, a second Z-axis slide table 432 that moves up and down along the second Z-axis slide rail 431, and a sixth linear drive source 433 that drives the second Z-axis slide table 432 to move up and down. The laser head 41 is fixed on the second Z-axis slide table 432. The second X-axis guide rail 421 and the second Z-axis linear module 43 are used to adjust the position of the laser head 41 in the X and Z directions, respectively, to cope with different situations, such as adapting to batteries of different widths and heights to ensure that the laser beam can cover the entire surface to be processed; adjusting the height of the laser head 41 in the Z direction according to the focal length required for laser processing to obtain the best spot effect; during the process of switching the processing surface by rotating the battery around its axis, driving the laser head 41 to move in the X or Z direction to safely avoid the rotation path and prevent collisions; and when a set of laser film removal mechanisms 4 needs to work in conjunction with two sets of clamping mechanisms 2 and carrier mechanisms 3, the laser head 41 can be quickly and accurately positioned above the predetermined working position above the other set of clamping mechanisms 2 currently being processed by the linkage adjustment of the X and Z directions, so as to achieve efficient multi-station alternating processing.

[0045] In this embodiment, the first linear drive source 22, the second linear drive source 333, the third linear drive source 323, the fourth linear drive source 343, the fifth linear drive source 423, and the sixth linear drive source 433 are one of the following: ball screw pair, synchronous belt drive group, linear motor, hydraulic transmission group, and pneumatic transmission group. Their purpose is to drive the target component to move linearly in a specific direction, providing a power basis for the movement of various parts of the device. In this embodiment, the rotary drive source 23 is one of the following: motor and rotary cylinder. Its purpose is to provide controllable rotational power to drive the clamping mechanism 2, together with the clamped battery, to rotate around its central axis at a preset angle, ensuring that the different processed surfaces of the battery can be accurately aligned with the laser head 41 in sequence.

[0046] In this embodiment, the battery carrier 31 is equipped with a sensor for detecting whether a battery is placed on it. The sensor is connected to the control cabinet 5 and provides a battery placement status signal to the control cabinet 5. The control cabinet 5 can determine whether the processing start conditions are met. Only when it is confirmed that the battery has been correctly placed will the subsequent transfer and laser processing processes be allowed or automatically started. This effectively avoids the risk of the equipment running dry, mispositioning, or even mechanical collisions due to the operator forgetting to place the battery (empty load) or the battery being seriously misplaced. This significantly improves the safety and reliability of the equipment operation and reduces equipment damage caused by misoperation. The sensor in this embodiment can be one of a weighing sensor, a pressure film sensor, or a photoelectric sensor. Of course, other sensors that can detect whether the battery carrier 31 has a battery can also be used in this embodiment. Their core function is to confirm that the battery to be processed has been correctly placed on the carrier, preventing empty load operation or mispositioning. The battery carrier 31 is provided with at least one limiting surface that abuts the battery for initial positioning of the placed battery, facilitating subsequent transfer and clamping alignment. In this embodiment, casters are also provided below the frame 1 and control cabinet 5, enabling the entire square aluminum-cased battery surface insulation film removal device to have convenient mobility and position adjustment capabilities. Operators can easily move the equipment between different locations within the workshop, for example, deploying it next to different rework lines or moving it to the maintenance area according to production needs.

[0047] When using the aforementioned square aluminum-cased battery surface insulating film removal device to remove the insulating film from the surface of a square aluminum-cased battery, the battery to be processed is first placed in the designated position on the battery carrier 31, and the sensor on the battery carrier 31 detects the battery positioning signal. After the operator presses the start button, the control cabinet 5 first controls the first drive assembly (the Y-axis linear module 33 and the first X-axis linear module 32 work together) to move the battery carrier 31 carrying the battery to below the clamping station. Then, the first Z-axis linear module 34 in the first drive assembly is activated to lift the battery carrier 31 so that the battery reaches the predetermined clamping height. Subsequently, the clamping mechanism... The first linear drive source 22 of the laser removal mechanism 2 drives the paired clamping blocks 21 to move towards each other (i.e., both clamping blocks 21 move towards the center simultaneously, or one is fixed and the other movable clamping block 21 moves towards the fixed clamping block 21), firmly clamping the battery; after clamping is completed, the first Z-axis linear module 34 in the first drive assembly drives the battery carrier 31 to descend and detach from the battery, avoiding interference with subsequent processing and battery rotation; immediately afterward, the rotation drive source 23 drives the clamping mechanism 2, together with the battery, to rotate around its central axis, aligning the first surface to be processed with the laser head 41; the second drive assembly (second X-axis linear module 4) of the laser removal mechanism 4... 2. The second Z-axis linear module 43) adjusts the position and focal length of the laser head 41 according to a preset program; after adjustment, the laser head 41 emits a laser beam to scan the insulating film on the current battery surface; after processing one surface, the rotation drive source 23 drives the battery to rotate 90° or other predetermined angles, rotating the next surface to be processed to the position of the laser head 41, repeating the laser film removal process until all surfaces of the battery that need to be processed are processed; the other predetermined angles are for some specially designed batteries, such as those with windows on a specific surface and some areas without insulating film coverage, in which case adjustments can be made according to actual needs. The surface distribution is optimized, and the rotation angle can be flexibly set to process only the surface that needs to be de-coated, skipping the surface without coating. After processing, the control cabinet 5 controls the clamping mechanism 2 to release the battery. The first drive component drives the battery carrier 31 to rise to the clamping height to receive the battery, then descends and moves out of the clamping station, returning to the initial loading position. The operator removes the laser-treated battery. At this time, the adhesion of the insulating film on the battery surface has been significantly weakened by the laser. The operator can easily peel off the insulating film manually, or connect to the subsequent automated film peeling equipment to complete the film peeling. After peeling, there are basically no large pieces of residual adhesive on the battery surface, and the cleanliness is significantly improved.

[0048] When using the square aluminum-shell battery surface insulating film removal device described in this invention to remove the insulating film from the surface of a square aluminum-shell battery, the laser film removal mechanism 4 directly acts on the insulating film on the battery surface. Laser pretreatment significantly reduces the adhesion between the insulating film and the battery casing, making subsequent film removal operations extremely easy and greatly improving the film removal efficiency. This effectively avoids the problem of large amounts of granular residue generated by traditional film removal methods. Furthermore, the rotation function of the clamping mechanism 2 enables continuous automated laser film removal processing on multiple sides of the square battery. The coordinated action of the carrier mechanism 3 and the clamping mechanism 2 ensures accurate positioning and stable clamping of the battery at the clamping station, as well as timely avoidance and safe removal and placement of the carrier after processing.

[0049] This invention also includes a control cabinet 5. The control cabinet 5 coordinates the sequence, timing, and position parameters of various actions, such as the transfer and positioning of the carrier mechanism 3, the clamping, loosening, and rotation of the clamping mechanism 2, and the laser emission of the laser film removal mechanism 4. This achieves automated operation of the entire film removal process, significantly reducing manual intervention and improving processing speed and consistency. Furthermore, the battery carrier 31 is equipped with a sensor to detect whether a battery is placed on it. Only when the sensor confirms that the battery is correctly placed on the carrier will the control cabinet 5 initiate the subsequent transfer and processing steps. This avoids ineffective equipment operation, positioning errors, or even collision risks due to no-load or improper placement, ensuring the reliability and safety of the processing. Simultaneously, this also provides basic signals for cycle time control and process management of the automated production line.
