Description

Technical Field

[0001] This application relates to the field of film application technology, and in particular to a film application machine and battery production equipment. Background Technology

[0002] With the widespread use of electronic products, applying protective films to product surfaces is an effective way to protect products in their factory condition and is widely used across various industries. For example, in the manufacturing process of battery modules, protective films are usually applied to the surface of the battery modules to prevent scratches or contamination. Currently, the industry typically uses film-applying machines for automated film application. However, as these machines age, wear and tear on the application mechanism can lead to poor film application, resulting in bubbles and wrinkles, leading to high rework rates and increased production costs. Utility Model Content

[0003] In view of the above problems, this application provides a film applicator and battery production equipment, which aims to reduce the generation of film bubbles and wrinkles, improve the film applicator yield, and reduce the rework rate.

[0004] In a first aspect, this application provides a film applicator, which includes a machine base, a moving module, a workpiece positioning mechanism, and a film applicator. The workpiece positioning mechanism is disposed on the machine base and is used to position the workpiece; the film applicator is connected to the moving module, which is used to drive the film applicator to move between multiple preset stations on the machine base; the film applicator includes a film suction component and an elastic film pressing component, the film suction component is used to suction the protective film, and the elastic film pressing component is used to move along the surface of the workpiece to apply the protective film released by the film suction component to the surface of the workpiece.

[0005] The technical solution of this application involves setting a workpiece positioning mechanism on the machine base to position the workpiece (e.g., a battery module), ensuring the workpiece is in a suitable and fixed state for film application, thus preventing movement or tilting of the workpiece during subsequent film application and resulting in poor film application. A moving module drives the film application mechanism to move between multiple preset stations (e.g., film picking station and film application station) to achieve film picking and application operations. The film application mechanism includes a film suction component and an elastic film pressing component. When the film application mechanism is at the film picking station, the film suction component generates negative pressure to adsorb the protective film. Then, driven by the moving module, the film application mechanism moves to the film application station. At this point, the film application mechanism is above the workpiece positioning mechanism. The negative pressure of the film suction component is released to release the protective film onto the workpiece surface. The elastic film pressing component presses against one end of the protective film and reciprocates along the workpiece surface under the drive of the moving module to remove air bubbles and wrinkles between the protective film and the workpiece, allowing the protective film to adhere to the workpiece surface. Furthermore, the elastic pressure film assembly possesses a certain degree of elasticity, allowing for adaptive elastic floating adjustment during its pressing against the workpiece surface. This enables the laminating mechanism to self-compensate for minor wear, eliminating bubbles and wrinkles caused by dimensional tolerances. The elastic pressure film assembly also has a certain self-adjusting range, effectively preventing sagging and wrinkles caused by changes in film material, thus avoiding rework due to material variations. This enhances the flexibility and compatibility of the laminating machine, enabling rapid changeovers. The laminating machine using this solution reduces the generation of bubbles and wrinkles, improves laminating yield, reduces rework rates, and ultimately increases production efficiency and saves costs.

[0006] In some embodiments, the moving module includes an X-axis module mounted on the machine tool, a Y-axis module connected to the X-axis module, and a Z-axis module connected to the Y-axis module. The film-applying mechanism is connected to the Z-axis module. The X-axis module drives the film-applying mechanism to reciprocate along a first direction, the Y-axis module drives the film-applying mechanism to reciprocate along a second direction, and the Z-axis module drives the film-applying mechanism to reciprocate along a third direction, wherein the first, second, and third directions intersect each other. In this embodiment, the cooperation of the X-axis module, Y-axis module, and Z-axis module allows the film-applying mechanism to move freely in three dimensions: the X-axis, Y-axis, and Z-axis, resulting in a wider range of motion and more flexible movement. Furthermore, the moving module adopts a truss-structured three-axis module, enabling linear transport under heavy loads and providing higher motion accuracy, thereby improving film-applying accuracy.

[0007] In some embodiments, the elastic film-pressing assembly includes a film-pressing lifting drive, a mounting base, a scraper, and an elastic element. The film-pressing lifting drive is mounted on the film-suction assembly and is driven to connect to the mounting base. The scraper is rotatably mounted on the mounting base, and the elastic element is located at the connection between the mounting base and the scraper. When the moving module drives the film-applying mechanism to reciprocate along a first direction, the scraper is used to apply the protective film released by the film-suction assembly to the workpiece surface along the first direction, and can perform elastic floating adjustment under the action of the elastic element. In this embodiment, the use of a straight scraper in conjunction with the elastic element can achieve adaptive floating adjustment of the film application. By applying force to the elastic element, the scraper can be adjusted to a suitable position for adaptive compensation, allowing the scraper to better adhere to the surface of the workpiece. This effectively solves the problem of rollers not being able to reach certain areas, thereby effectively reducing film bubbles and wrinkles and improving the film application yield.

[0008] In some embodiments, the film suction assembly includes a first support, a second support, a vacuum suction plate, and a swing drive. The first support is connected to the movable module, the second support is hinged to the first support, the swing drive is fixed to the second support, and the drive end of the swing drive is hinged to the first support and can extend and retract. The vacuum suction plate is fixed to the bottom of the second support, and the elastic film pressing assembly is disposed on one side of the vacuum suction plate along a first direction. In this embodiment, by setting the film suction assembly as a hinged structure, when the drive end of the swing drive is in a retracted state, the end of the vacuum suction plate away from the elastic film pressing assembly is raised upward by a preset angle. This allows the end of the protective film near the elastic film pressing assembly to first adhere to the workpiece during the release of the protective film by the vacuum suction plate. Then, as the elastic film pressing assembly moves, the protective film gradually adheres to the workpiece surface towards the side where the vacuum suction plate is raised. This better simulates the manual film application method, allowing the protective film to be tilted and gradually adhere to the workpiece surface from one end to the other, thereby reducing the generation of bubbles and wrinkles during the film application process.

[0009] In some embodiments, the vacuum suction plate has a first region and a second region, each with a plurality of suction cups. The suction cups in the first region are connected to a vacuum generator via a first air path, and the suction cups in the second region are connected to the vacuum generator via a second air path. Both the first and second air paths are equipped with negative pressure detection devices. In this embodiment, by providing negative pressure detection devices in both the first and second air paths, the negative pressure in each air path is detected to ensure that the negative pressure meets requirements. This allows for monitoring of whether the protective film is properly adhered, thus ensuring the reliability of subsequent film application.

[0010] In some embodiments, the workpiece positioning mechanism includes a support module and a clamping and flipping module. The support module supports the workpiece, and the clamping and flipping module clamps the workpiece on the support module and drives the workpiece to flip. In this embodiment, the support module supports the workpiece to facilitate workpiece loading. The clamping and flipping module clamps and fixes the workpiece, preventing movement during the film application process and avoiding poor film application. After film application is complete, the clamping and flipping module drives the workpiece to flip so that the side with the protective film is facing down, facilitating the workpiece's entry into the next process and improving production efficiency.

[0011] In some embodiments, the support module is vertically and flexibly mounted on the machine base. The clamping and flipping module includes a first clamping and flipping component, a second clamping and flipping component, and a lateral movement drive. The first and second clamping and flipping components are located on opposite sides of the support module and cooperate with each other to clamp and flip the workpiece. The first clamping and flipping component is movably mounted on the machine base, and the lateral movement drive is used to drive the first clamping and flipping component to move closer to or away from the second clamping and flipping component. In this embodiment, the support module is vertically and flexibly mounted. When it is necessary to flip the workpiece, the support module lowers to a certain height, which can avoid interfering with the flipping action of the clamping and flipping module. By driving the first clamping and flipping component to move through the lateral movement drive, the distance between the first and second clamping and flipping components can be adjusted, thereby better adapting to the clamping of workpieces of different sizes.

[0012] In some embodiments, the laminating machine further includes a film supply mechanism, a film pulling mechanism, a film topping mechanism, and a film cutting mechanism disposed on the machine base. The film supply mechanism provides a protective film; the film pulling mechanism stretches the protective film provided by the film supply mechanism to a preset position along a first direction; the film topping mechanism cooperates with the laminating mechanism after the protective film is stretched to the preset position to clamp the film head of the protective film; the film cutting mechanism cuts off one end of the protective film away from the film topping mechanism, so that the laminating mechanism can absorb the cut protective film. In this embodiment, through the cooperation of the workpiece positioning mechanism, the film supply mechanism, the film pulling mechanism, the film topping mechanism, the film cutting mechanism, the laminating mechanism, and the moving module, workpiece positioning can be achieved, and a series of automated operations such as film supply, film pulling, film topping, film cutting, and film laminating can be realized, thereby achieving automated film laminating on the workpiece surface and improving production efficiency.

[0013] In some embodiments, the film supply mechanism includes a base mounted on the machine platform, and a film preparation assembly and a film pulling assembly mounted on the base. The film preparation assembly provides a protective film and conveys it toward the film pulling mechanism; the film pulling assembly clamps the protective film and pulls it taut toward the side away from the film pulling mechanism after the film pulling mechanism stretches the protective film to a preset position, thereby tensioning the protective film to be cut. In this embodiment, the film pulling assembly can pull the end of the protective film away from the film head toward the side away from the film pulling mechanism, thus ensuring the accuracy of the protective film in the length direction. Furthermore, tensioning the protective film also facilitates subsequent cutting by the film cutting mechanism, ensuring the flatness of the cut.

[0014] In some embodiments, the film preparation assembly includes a material rack, a film winding roller, a release liner peeling roller, and a film feeding roller. The material rack is disposed on the base and is used to hold a roll of film, which is a double-layer film having a protective film and a release liner. Multiple film winding rollers are rotatably disposed on the base and are used to wind and convey the film material pulled from the roll of film in a predetermined direction. The release liner peeling roller is rotatably disposed on the base and is used to wind release liner to peel the release liner from the protective film of the film material conveyed by the film winding rollers. The film feeding roller is rotatably disposed on the base and is used to convey the protective film toward the film pulling mechanism in a first direction. In this embodiment, the material rack is used to hold the roll of film to provide support. The film material of the roll of film is pulled out to a certain length from one end of the film head and wound around multiple film winding rollers. The multiple film winding rollers tension the film material and convey it. After the film material is conveyed a certain distance, the release liner is wound around the release liner peeling roller. As the release liner peeling roller rotates continuously, the release liner can be peeled off from the protective film. The peeled release liner is then wound back onto the release liner peeling roller for recycling, while the protective film continues to be conveyed downstream via the film feeding roller. The film can be pre-fed towards the film pulling mechanism through the film winding roller and the film feeding roller, reducing the film pulling resistance.

[0015] In some embodiments, the film-pulling mechanism includes a film-pulling power component, a film-clamping component, and a transmission component. The film-clamping component is used to clamp or release the protective film. The film-pulling power component drives the film-clamping component to reciprocate along a first direction. The transmission component drives the film-pulling power component to the release paper peeling roller. The power output by the film-pulling power component is transmitted to the release paper peeling roller via the transmission component, causing the release paper peeling roller to rotate. In this embodiment, when the film-pulling mechanism is running, the power output by the film-pulling power component can be transmitted to the release paper peeling roller by the transmission component to drive the release paper peeling roller to rotate, thereby peeling the release paper from the protective film. In this way, the power of the film-pulling mechanism can drive the release paper peeling roller to rotate, eliminating the need for an additional power component to drive the release paper peeling roller, thus reducing costs and space requirements.

[0016] In some embodiments, the film-pulling assembly includes a film-pulling clamping module and a film-pulling drive component. The base is provided with a slide rail extending along a first direction. The film-pulling clamping module is slidably connected to the slide rail. The film-pulling clamping module is used to clamp or release the protective film. The film-pulling drive component drives the film-pulling clamping module to reciprocate along the slide rail. In this embodiment, the sliding cooperation between the film-pulling clamping module and the slide rail can improve the movement accuracy of the film-pulling clamping module in the first direction, thereby ensuring the accuracy of subsequent film cutting.

[0017] In some embodiments, the film supply mechanism further includes a film pushing assembly disposed on the base. The film pushing assembly has a retractable drive rod, which extends after the film cutting mechanism cuts the protective film to push the roll film open. In this embodiment, by providing the film pushing assembly, when the film cutting mechanism cuts the protective film, the drive rod of the film pushing assembly extends to push the roll film open, so that the roll film is completely separated from the cut protective film, thereby avoiding interference with the subsequent adsorption of the protective film.

[0018] In some embodiments, the film supply mechanism further includes a first material detection sensor disposed on the base, the first material detection sensor being used to detect whether the roll of film on the film preparation assembly is used up. In this embodiment, the first material detection sensor can detect whether the roll of film is used up, so that the operator can keep track of the status of the roll of film in a timely manner.

[0019] In some embodiments, the film supply mechanism further includes a second material detection sensor disposed on the base. The second material detection sensor is used to detect whether the release paper on the film preparation assembly is broken. In this embodiment, the second material detection sensor can detect whether the release paper is broken, so that the operator can promptly grasp the status of the release paper.

[0020] In some embodiments, the top film mechanism includes a transverse module disposed on the machine base, a top film drive unit drivenly connected to the transverse module, and a top film component drivenly connected to the top film drive unit. The transverse module is used to drive the top film drive unit and the top film component to reciprocate along a first direction, and the top film drive unit is used to drive the top film component to move up and down. In this embodiment, by cooperating with the transverse module and the top film drive unit, the transverse movement and vertical lifting of the top film component can be realized, making the position of the top film component more flexible and better suited for film application to different workpieces.

[0021] In some embodiments, the top membrane mechanism further includes a flexible cover, which at least partially covers the periphery of the transverse module and is capable of telescoping along a first direction. In this embodiment, the flexible cover provides protection for the transverse module, and its telescoping capability along the first direction does not interfere with the movement of the top membrane drive component on the transverse module.

[0022] In some embodiments, the film-cutting mechanism is disposed between the film-supplying mechanism and the top-film mechanism. The film-cutting mechanism includes a cutter holder, a cutter assembly, and a film-cutting drive member disposed on the cutter holder. The cutter assembly includes an upper cutter and a lower cutter that are movable relative to each other. The film-cutting drive member is drivenly connected to the cutter assembly and is used to drive the upper cutter and the lower cutter to move closer or further apart. In this embodiment, when film cutting is not required, the upper cutter and the lower cutter move further apart, and the protective film output by the film-supplying mechanism can pass between the upper cutter and the lower cutter and be conveyed forward normally. When film cutting is required, the film-cutting drive member drives the upper cutter and the lower cutter to move closer together to generate a shearing force on the protective film, thereby cutting the protective film.

[0023] In some embodiments, the film-cutting mechanism further includes a safety door equipped with a safety monitoring switch. The safety monitoring switch monitors the status of the safety door and sends a feedback signal to the control system. The control system prevents the film-cutting mechanism from operating when the safety door is open. Thus, the film-cutting mechanism cannot operate when the safety door is open, thereby improving its safety.

[0024] In some embodiments, the film cutting mechanism further includes a switching valve for opening or closing the power source of the film cutting drive. Thus, when the switching valve is closed, the power source of the film cutting drive cannot output power, preventing the film cutting drive from driving the cutter assembly and improving the safety of the film cutting mechanism.

[0025] In some embodiments, the film-cutting mechanism further includes a safety block having a first position located between the upper cutter and the lower cutter, and a second position moved out of the space between the upper cutter and the lower cutter. Thus, when maintenance of the cutter assembly is required, the safety block can be moved to the first position, allowing it to separate the upper and lower cutters, preventing them from closing and ensuring operator safety.

[0026] In this embodiment, by setting up a safety door, a switching valve, and a safety block equipped with a safety detection switch, the safety of the film cutting mechanism can be effectively improved, and the protection level for operators can be enhanced.

[0027] In some embodiments, two sets of film-pulling mechanisms are arranged opposite each other along a second direction. Each film-pulling mechanism has a corresponding film-supplying mechanism on one side along a first direction. A film-cutting mechanism is provided between each film-pulling mechanism and its corresponding film-supplying mechanism. A top-film mechanism is provided on the side of each film-pulling mechanism away from the other film-pulling mechanism. The workpiece positioning mechanism is located between the two film-pulling mechanisms, wherein the first direction intersects the second direction. In this embodiment, the film-supplying mechanism, film-pulling mechanism, top-film mechanism, and film-cutting mechanism are arranged side-by-side in two sets along the second direction, sharing a workpiece positioning mechanism, a moving module, and a film-applying mechanism. The overall layout is compact, with high space utilization, and can effectively improve production efficiency.

[0061] Currently, with the development of the market, the application scope of power batteries is becoming increasingly wide. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power, and solar power plants, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace, among other fields. As the application areas of power batteries continue to expand, the market demand is also constantly increasing.

[0062] In the manufacturing process of power battery modules, a protective film is typically applied to the surface of the battery module to prevent scratches or contamination. Currently, the industry commonly uses laminating machines for automated film application. However, as these machines age, wear and tear on the laminating mechanism can lead to poor film application. Due to dimensional tolerances, the worn areas can cause uneven stress on the film surface, resulting in bubbles and wrinkles, leading to high rework rates and increased production costs. Furthermore, changes in the film material can cause wrinkles and bubbles during application, resulting in low equipment compatibility.

[0063] Based on this, this application proposes a film applicator 100 and a battery production equipment.

[0064] The film applicator 100 can be used to apply flexible auxiliary materials to the surface of a workpiece 200, wherein the workpiece 200 can be a battery cell, battery module, mobile phone, tablet, or other product, and the flexible auxiliary material can be a protective film 301 or other flexible functional layer. For ease of explanation, the following embodiments use an example of the film applicator 100 applying a protective film 301 to a battery module. For clarity, in the following embodiments, the first direction is the length direction of the film applicator 100 (e.g., the X-axis direction), the second direction is the width direction of the film applicator 100 (e.g., the Y-axis direction), and the third direction is the height direction of the film applicator 100 (e.g., the Z-axis direction).

[0065] According to some embodiments of this application, refer to Figures 1 to 3 This application provides a film applicator 100. The film applicator 100 includes a machine base 10, a moving module 20, a workpiece positioning mechanism 30, and a film applicator 40. The workpiece positioning mechanism 30 is disposed on the machine base 10 and is used to position the workpiece 200; the film applicator 40 is connected to the moving module 20, and the moving module 20 is used to drive the film applicator 40 to move between multiple preset workstations on the machine base 10; the film applicator 40 includes a film suction assembly 41 and an elastic film pressing assembly 42. The film suction assembly 41 is used to suction the protective film 301, and the elastic film pressing assembly 42 is used to move along the surface of the workpiece 200 to adhere the protective film 301 released by the film suction assembly 41 to the surface of the workpiece 200.

[0066] The machine base 10 serves as the main support structure of the laminating machine 100, providing mounting positions for the moving module 20, the workpiece positioning mechanism 30, and other functional mechanisms. The machine base 10 can employ a metal frame structure to ensure strong rigidity and structural stability. The frame structure of the machine base 10 can house an electrical control system, a pneumatic system, etc., and the frame structure of the machine base 10 can be surrounded by a protective panel to safeguard the internal systems. To ensure the stability of the machine base 10 on the ground, the bottom of the machine base 10 is equipped with multiple support legs, each with an adjustable height to better adapt to uneven ground. Optionally, the support legs can be configured with rollers to facilitate movement of the entire machine.

[0067] A workpiece positioning mechanism 30 is mounted on the machine base 10 to position the workpiece 200 (e.g., a battery module), ensuring that the workpiece 200 is in a suitable state for film application and is fixed in place to prevent movement or tilting of the workpiece 200 during subsequent film application, which could lead to poor film application. Before film application, the workpiece 200 to be filmed can be placed on the workpiece positioning mechanism 30 manually or by a robot, with the side of the workpiece 200 to be filmed facing upwards, to facilitate subsequent film application. The workpiece positioning mechanism 30 includes, but is not limited to, using mechanical grippers, positioning grooves, or other structures to position the workpiece 200. For example, the workpiece positioning mechanism 30 may include a support module 31 and a clamping and flipping module 32. The support module 31 supports the workpiece 200, and the clamping and flipping module 32 clamps and fixes the workpiece 200. Furthermore, the clamping and flipping module 32 can also flip the workpiece 200 after film application so that the filmed side of the workpiece 200 faces downwards, facilitating the workpiece 200 to proceed to the next process.

[0068] The moving module 20 can be mounted on the machine base 10 or independently mounted next to the machine base 10. The moving module 20 is connected to the film application mechanism 40, and can drive the film application mechanism 40 to move between multiple preset stations on the machine base 10. For example, the moving module 20 can move the film application mechanism 40 to a film picking station suitable for film picking, and to a film application station located above the workpiece positioning mechanism 30. The moving module 20 includes, but is not limited to, a multi-axis module with a truss structure, or a robotic arm capable of free movement in three-dimensional space, as long as it can drive the film application mechanism 40 to move freely within the working area; no specific limitation is made here.

[0069] The film application mechanism 40 includes a film suction component 41 and an elastic film pressing component 42. The film suction component 41 can generate negative pressure through a vacuum generator to adsorb the protective film 301, and release the adsorbed protective film 301 when the air path of the vacuum generator is disconnected. The elastic film pressing component 42 is used to reciprocate along the surface of the workpiece 200 during the process of the film suction component 41 releasing the protective film 301 onto the surface of the workpiece 200, so as to remove air bubbles and wrinkles between the protective film 301 and the workpiece 200, so that the protective film 301 can adhere to the surface of the workpiece 200. Furthermore, the elastic film pressing component 42 has a certain degree of elasticity and can make adaptive elastic floating adjustment during its pressing onto the surface of the workpiece 200. This allows the film application mechanism 40 to adaptively compensate for minor wear through its own elasticity, thereby eliminating air bubbles and wrinkles caused by dimensional tolerances. In addition, the elastic film pressing component 42 has a certain self-adjustment space, which can also effectively avoid wrinkles caused by sagging due to changes in film material, and avoid rework caused by material changes.

[0070] The technical solution of this application involves setting a workpiece positioning mechanism 30 on the machine tool 10. The workpiece positioning mechanism 30 positions the workpiece 200 (e.g., a battery module) so that the workpiece 200 is kept in a suitable state for film application and is fixed, thereby preventing the workpiece 200 from moving or tilting during the subsequent film application process, which would lead to poor film application. The film application mechanism 40 is driven by the moving module 20 to move between multiple preset stations (e.g., film picking station and film application station) to realize film picking and film application operations. The film application mechanism 40 includes a film suction component 41 and an elastic film pressing component 42. When the film application mechanism 40 is in the film taking position, the film suction component 41 generates negative pressure to adsorb the protective film 301. Then, the film application mechanism 40 moves to the film application position under the drive of the moving module 20. At this time, the film application mechanism 40 is located above the workpiece positioning mechanism 30. The negative pressure of the film suction component 41 is removed to release the protective film 301 onto the surface of the workpiece 200. The elastic film pressing component 42 presses against one end of the protective film 301 and moves back and forth along the surface of the workpiece 200 under the drive of the moving module 20 to remove air bubbles and wrinkles between the protective film 301 and the workpiece 200, so that the protective film 301 can adhere to the surface of the workpiece 200. Furthermore, the elastic pressure film assembly 42 possesses a certain degree of elasticity, enabling adaptive elastic floating adjustment during its pressing against the surface of the workpiece 200. This allows for self-compensation when minor wear occurs in the film application mechanism 40, eliminating bubbles and wrinkles caused by dimensional tolerances. The elastic pressure film assembly 42 also has a certain self-adjusting space, effectively preventing wrinkles caused by sagging due to changes in film material, thus avoiding rework caused by material variations. This enhances the flexibility and compatibility of the film application machine 100, enabling rapid changeover. The film application machine 100 using this solution can reduce the generation of bubbles and wrinkles, improve film application yield, reduce rework rate, thereby increasing production efficiency and saving costs.

[0071] like Figure 1 As shown, in some embodiments, the moving module 20 includes an X-axis module 21 disposed on the machine base 10, a Y-axis module 22 connected to the X-axis module 21, and a Z-axis module 23 connected to the Y-axis module 22. The film application mechanism 40 is connected to the Z-axis module 23. The X-axis module 21 is used to drive the film application mechanism 40 to reciprocate along a first direction, the Y-axis module 22 is used to drive the film application mechanism 40 to reciprocate along a second direction, and the Z-axis module 23 is used to drive the film application mechanism 40 to reciprocate along a third direction. The first direction, the second direction, and the third direction intersect each other.

[0072] In this embodiment, the moving module 20 is a three-axis module, capable of linear motion in three dimensions: X-axis, Y-axis, and Z-axis. Specifically, the X-axis module 21 extends along a first direction (i.e., the X-axis direction) and drives the Y-axis module 22 to reciprocate along the first direction. The Y-axis module 22 extends along a second direction (i.e., the Y-axis direction) and drives the Z-axis module 23 to reciprocate along the second direction. The Z-axis module 23 extends along a third direction (i.e., the Z-axis direction) and drives the film-applying mechanism 40 to reciprocate along the third direction. Thus, through the cooperation of the X-axis module 21, Y-axis module 22, and Z-axis module 23, the film-applying mechanism 40 can move freely in the three dimensions of the X-axis, Y-axis, and Z-axis, resulting in a wider range of motion and more flexible movement. Furthermore, the moving module 20 adopts a truss structure for its three-axis design, enabling linear transport under heavy loads and providing higher motion accuracy, thereby improving film-applying precision. Among them, the X-axis module 21, Y-axis module 22 and Z-axis module 23 include, but are not limited to, using ball screws, belt drive mechanisms, gear rack mechanisms, linear motors and other means to achieve linear motion.

[0073] Optionally, the moving module 20 includes two X-axis modules 21 disposed on opposite sides of the machine base 10 along the second direction. Each X-axis module 21 is connected to both ends of the Y-axis module 22 via a bracket, and the Z-axis module 23 is slidably mounted on the Y-axis module 22. In this way, the two X-axis modules 21 and the Y-axis module 22 combine to form a gantry structure, which has higher overall rigidity and a more stable structure, making it easier to withstand greater loads. This results in more stable and precise movement of the film-applying mechanism 40.

[0074] like Figure 3 As shown, in some embodiments, the elastic film pressing assembly 42 includes a film pressing lifting drive 421, a mounting base 422, a scraper 423, and an elastic element 424. The film pressing lifting drive 421 is mounted on the film suction assembly 41 and drives the mounting base 422. The scraper 423 is rotatably mounted on the mounting base 422. The elastic element 424 is located at the connection between the mounting base 422 and the scraper 423. When the moving module 20 drives the film application mechanism 40 to reciprocate along the first direction, the scraper 423 is used to apply the protective film 301 released by the film suction assembly 41 to the surface of the workpiece 200 along the first direction, and can be elastically floated and adjusted under the action of the elastic element 424.

[0075] In this embodiment, the film pressing and lifting drive 421 is used to drive the mounting base 422 to move up and down along a third direction (i.e., the Z-axis direction), thereby driving the scraper 423 to move up and down. The film pressing and lifting drive 421 may include, but is not limited to, a cylinder, a hydraulic cylinder, an electric push rod, or other linear drive mechanisms. Optionally, the film pressing and lifting drive 421 may be a cylinder, with the piston rod connected to the mounting base 422. The extension and retraction of the piston rod drives the mounting base 422 and the scraper 423 on the mounting base 422 to move up and down. The scraper 423 is generally rectangular, with its thickness direction parallel or substantially parallel to the first direction, its length direction parallel or substantially parallel to the second direction, and its width direction parallel or substantially parallel to the third direction. The scraper 423 can be rotatably connected to the mounting base 422 on both sides along its length via bearings or a rotating shaft. An elastic element 424 is provided at the connection between the scraper 423 and the mounting base 422, so that the scraper 423 has a certain degree of freedom of movement and can achieve elastic floating adjustment under the action of the elastic element 424.

[0076] At the film suction station, the scraper 423 is in a higher retracted position. At this time, the bottom side of the scraper 423 is flush with or higher than the bottom surface of the film suction assembly 41 to avoid interference with the film suction of the film suction assembly 41. When it moves to the film application position, the film pressing and lifting drive 421 drives the scraper 423 to extend downward, and the bottom surface of the scraper 423 protrudes from the bottom surface of the film suction assembly 41, which is beneficial for the scraper 423 to apply the film. During the film application process, one side of the scraper 423 in the width direction presses against the protective film 301. The moving module 20 drives the scraper 423 to move back and forth along the first direction on the surface of the workpiece 200 to attach the protective film 301 to the surface of the workpiece 200. During this process, the elastic element 424 allows the scraper 423 to make adaptive elastic floating adjustment to better fit the surface of the workpiece 200. The elastic element 424 includes, but is not limited to, springs, sheet springs, or other elastic structural components.

[0077] Traditional film application mechanisms typically use rollers for rolling film application. When the rollers wear down, they cannot fully adhere to the surface of the workpiece 200, resulting in areas the rollers cannot reach, leading to air bubbles and wrinkles in the film application. Compared to traditional roller-based film application mechanisms, the film application mechanism 40 of this application uses a straight scraper 423 in conjunction with an elastic element 424 to achieve adaptive floating adjustment of the film application. The elastic element 424, under pressure, can adjust the scraper 423 to a suitable position for adaptive compensation, allowing the scraper 423 to better adhere to the surface of the workpiece 200. This effectively solves the problem of incomplete rolling by rollers, thereby effectively reducing air bubbles and wrinkles in the film application and improving the film application yield.

[0078] Optionally, the scraper 423 can be a flexible scraper. For example, the scraper 423 can be made of flexible materials such as rubber or silicone, giving it a certain degree of flexibility so that it can better adhere to the surface of the workpiece 200, further reducing film bubbles and wrinkles, and improving the film application yield. Furthermore, the flexible contact between the scraper 423 and the protective film 301 prevents the scraper 423 from scratching or tearing the protective film 301.

[0079] like Figure 3 As shown, in some embodiments, the film suction assembly 41 includes a first support 411, a second support 412, a vacuum suction plate 413, and a swing drive 414. The first support 411 is connected to the movable module 20, the second support 412 is hinged to the first support 411, the swing drive 414 is fixed to the second support 412, the driving end of the swing drive 414 is hinged to the first support 411 and can extend and retract, the vacuum suction plate 413 is fixed to the bottom of the second support 412, and the elastic film pressing assembly 42 is disposed on one side of the vacuum suction plate 413 along the first direction.

[0080] The first support 411 and the second support 412 can be configured as plate-like structures arranged opposite each other along a first direction. The side of the first support 411 away from the second support 412 can be connected and fixed to the Z-axis module 23 of the moving module 20, and the other side of the first support 411 can be hinged to the second support 412 through a hinge structure. A swing drive member 414 is fixed to the side of the second support 412 away from the first support 411. The drive end of the swing drive member 414 is hinged to the first support 411 and can extend and retract. When the drive end of the swing drive member 414 extends, it can drive the second support 412 to swing away from the first support 411, thereby enabling the vacuum suction plate 413 fixed to the bottom of the second support 412 to switch between a horizontal state and an inclined state. The swing drive member 414 includes, but is not limited to, a drive structure with an extendable drive end, such as a cylinder, a hydraulic cylinder, or a linear push rod. Optionally, the swing drive member 414 is a cylinder, and the piston rod of the cylinder is hinged to the first support 411 through a hinge structure.

[0081] In this embodiment, at the film taking station, the second bracket 412 can be driven to swing by extending the driving end of the swing drive 414 so that the vacuum suction plate 413 is in a horizontal state, thereby better adsorbing the protective film 301. During the film application process, the driving end of the swing drive 414 retracts, causing the vacuum suction plate 413 to be tilted relative to the horizontal plane. At this time, the end of the vacuum suction plate 413 away from the elastic film pressing assembly 42 is raised at a preset angle. As the vacuum suction plate 413 releases the protective film 301, the end of the protective film 301 closest to the elastic film pressing assembly 42 first adheres to the workpiece 200. Then, as the elastic film pressing assembly 42 moves, the protective film 301 gradually adheres to the surface of the workpiece 200 towards the side where the vacuum suction plate 413 is raised. Compared with directly releasing the protective film 301 horizontally onto the surface of the workpiece 200 for film application, the film application method of this application can better simulate the manual film application method, allowing the protective film 301 to be tilted and gradually adhered to the surface of the workpiece 200 from one end to the other, which is more conducive to reducing the generation of bubbles and wrinkles during the film application process.

[0082] like Figure 3 As shown, in some embodiments, the vacuum suction plate 413 has a first region and a second region. The first region and the second region are respectively provided with a plurality of suction cups 4131. The plurality of suction cups 4131 located in the first region are connected to the vacuum generator through a first air passage, and the plurality of suction cups 4131 located in the second region are connected to the vacuum generator through a second air passage. The first air passage and the second air passage are respectively provided with negative pressure detection devices.

[0083] In this embodiment, the bottom surface of the vacuum suction plate 413 is provided with multiple suction cups 4131, which are connected to a vacuum generator. When the air path of the vacuum generator is opened, the suction cups 4131 generate negative pressure, thereby adsorbing the protective film 301. When the air path of the vacuum generator is disconnected, the negative pressure of the suction cups 4131 is removed, thereby releasing the protective film 301. Optionally, the multiple suction cups 4131 are evenly arranged in a multi-row, multi-column array structure, making the force on the protective film 301 more uniform, thereby enabling more stable adsorption of the protective film 301. The vacuum suction plate 413 has a first region and a second region, and the first region and the second region are respectively provided with multiple suction cups 4131. The multiple suction cups 4131 located in the first region are connected to the vacuum generator through a first air path, and the multiple suction cups 4131 located in the second region are connected to the vacuum generator through a second air path. The first air path and the second air path are respectively provided with negative pressure detection devices. Thus, by using negative pressure detection devices in the first and second air paths to check whether the negative pressure in each path meets the requirements, the adhesion of the protective film 301 can be monitored to ensure its reliability during subsequent film application. Only when the negative pressure in both air paths meets the requirements does it indicate that the protective film 301 has been properly adhered. If the negative pressure in one or both air paths fails to meet the requirements, it indicates that the protective film 301 has not been properly adhered. The negative pressure detection devices include, but are not limited to, mechanical negative pressure gauges and electronic pressure sensors.

[0084] Please refer to Figure 1 and Figure 2 In some embodiments, the workpiece positioning mechanism 30 includes a support module 31 and a clamping and flipping module 32. The support module 31 is used to support the workpiece 200, and the clamping and flipping module 32 is used to clamp the workpiece 200 on the support module 31 and drive the workpiece 200 to flip.

[0085] In this embodiment, before applying the protective film, the workpiece 200 can be placed on the support module 31 for easy loading. When the film needs to be applied, the clamping and flipping module 32 clamps and fixes the workpiece 200 to prevent it from moving during the application process and causing poor application. After the film is applied, the clamping and flipping assembly can drive the workpiece 200 to flip so that the side of the workpiece 200 with the protective film 301 is facing down, so that the workpiece 200 can enter the next process and improve production efficiency.

[0086] like Figure 2As shown, in some embodiments, the support module 31 is movably mounted on the machine base 10, and the clamping and flipping module 32 includes a first clamping and flipping component 321a, a second clamping and flipping component 321b, and a transverse drive component 322. The first clamping and flipping component 321a and the second clamping and flipping component 321b are located on opposite sides of the support module 31. The first clamping and flipping component 321a and the second clamping and flipping component 321b cooperate with each other to clamp and flip the workpiece 200. The first clamping and flipping component 321a is movably mounted on the machine base 10, and the transverse drive component 322 is used to drive the first clamping and flipping component 321a to move closer to or away from the second clamping and flipping component 321b.

[0087] In this embodiment, the first clamping and flipping component 321a and the second clamping and flipping component 321b are arranged opposite to each other along a first direction, and the support module 31 is located between the first clamping and flipping component 321a and the second clamping and flipping component 321b. The support module 31 is used to support the workpiece 200. The first clamping and flipping component 321a can be used to clamp one end of the workpiece 200, and the second clamping and flipping component 321b can be used to clamp the other end of the workpiece 200. The workpiece 200 can be clamped and fixed by their cooperation. When it is necessary to flip the workpiece 200, the support module 31 lowers a certain height to avoid interfering with the flipping action of the clamping and flipping module 321b. The first clamping and flipping component 321a and the second clamping and flipping component 321b can perform flipping actions simultaneously to drive the workpiece 200 to flip. Exemplarily, both the first clamping and flipping assembly 321a and the second clamping and flipping assembly 321b include a support base 3211, a flipping drive member 3212 disposed on the support base 3211, and a gripper 3213 drivenly connected to the flipping drive member 3212. The gripper 3213 is used to clamp or release the workpiece 200, and the flipping drive member 3212 is used to drive the gripper 3213 to flip the workpiece 200. The flipping drive member 3212 includes, but is not limited to, an electric motor, a rotary cylinder, or other drive members capable of outputting rotational power.

[0088] The first clamping and flipping assembly 321a is movably mounted on the machine base 10 along a first direction. The transverse drive 322 is fixed to the machine base 10 and drivenly connected to the first clamping and flipping assembly 321a. The transverse drive 322 drives the first clamping and flipping assembly 321a to move along the first direction, so that the first clamping and flipping assembly 321a moves closer to or further away from the second clamping and flipping assembly 321b. In this way, the distance between the first clamping and flipping assembly 321a and the second clamping and flipping assembly 321b is adjustable, thereby better adapting to the clamping of workpieces 200 of different sizes. To improve the movement stability of the first clamping and flipping assembly 321a, the clamping and flipping module 32 optionally includes a guide rail 323 disposed on the machine base 10. The support base 3211 of the first clamping and flipping assembly 321a is slidably disposed on the guide rail 323, and the guide rail 323 can guide the movement of the first clamping and flipping assembly 321a.

[0089] like Figure 1 As shown, in some embodiments, the film applicator 100 further includes a film supply mechanism 50, a film pulling mechanism 60, a top film mechanism 70, and a film cutting mechanism 80 disposed on the machine base 10. The film supply mechanism 50 is used to provide a protective film 301; the film pulling mechanism 60 is used to stretch the protective film 301 provided by the film supply mechanism 50 along a first direction to a preset position; the top film mechanism 70 is used to cooperate with the film applicator 40 after the protective film 301 is stretched to the preset position to clamp the film head of the protective film 301; the film cutting mechanism 80 is used to cut off one end of the protective film 301 away from the top film mechanism 70, so that the film applicator 40 can absorb the cut protective film 301.

[0090] The film supply mechanism 50 is used to provide the protective film 301 required during film application, so that the protective film 301 can be continuously supplied, thereby improving production efficiency. In order to maximize the film supply, the roll film 300 is usually placed on the film supply mechanism 50 as raw material. The roll film 300 is generally a double-layer film consisting of a protective film 301 and a release paper 302. The film supply mechanism 50 can also automatically separate the protective film 301 from the release paper 302, and then convey the separated protective film 301 to the film stretching mechanism 60 for film stretching.

[0091] A film-stretching mechanism 60 is located on one side of the film-supplying mechanism 50 along the first direction. The film-stretching mechanism 60 clamps the film head of the protective film 301 supplied by the film-supplying mechanism 50 and stretches it to a preset position along the first direction. The length of the protective film 301 stretched by the film-stretching mechanism 60 can be adjusted according to the length of the workpiece 200 so that the surface of the workpiece 200 can be fully covered by the protective film 301. The film-stretching mechanism 60 may include a film-clamping assembly 62 and a film-stretching power assembly 61. The film-clamping assembly 62 is used to clamp or release the protective film 301, and the film-stretching power assembly 61 is used to drive the film-clamping assembly 62 to reciprocate along the first direction.

[0092] The top film mechanism 70 is located on the movement path of the film pulling mechanism 60. After the film pulling mechanism 60 stretches the protective film 301 to a preset position, the top film mechanism 70 is pushed out and can abut against the bottom side of the film head of the protective film 301. At this time, the film applying mechanism 40 can move above the top film mechanism 70 under the drive of the moving module 20. The top film mechanism 70 and the film applying mechanism 40 cooperate to clamp the film head, so as to facilitate the subsequent film cutting operation. The top film mechanism 70 may include a top film driving component 72 and a top film component 73. The top film driving component 72 is used to drive the top film component 73 to move up and down, and the top film component 73 is used to cooperate with the film applying mechanism 40 to clamp the film head.

[0093] The film cutting mechanism 80 is located between the film supply mechanism 50 and the top film mechanism 70. After the top film mechanism 70 and the film application mechanism 40 clamp the film head together, the film cutting mechanism 80 can cut off the end of the protective film 301 away from the top film mechanism 70, thereby obtaining a protective film 301 of the required length, so that the film application mechanism 40 can absorb the cut protective film 301 and perform subsequent film application operations. The film cutting mechanism 80 may include a film cutting drive 83 and a cutter assembly 82 drivenly connected to the film cutting drive 83. The film cutting mechanism 80 is used to drive the cutter assembly 82 to move in order to cut the film.

[0094] Understandably, the laminating machine 100 also includes a control system. The workpiece positioning mechanism 30, the moving module 20, the laminating mechanism 40, the film supply mechanism 50, the film pulling mechanism 60, the film topping mechanism 70, and the film cutting mechanism 80 are electrically connected to the control system. The laminating machine 100, through the control system, can control the workpiece positioning mechanism 30, the film supply mechanism 50, the film pulling mechanism 60, the film topping mechanism 70, the film cutting mechanism 80, the laminating mechanism 40, and the moving module 20 to complete corresponding operations according to a preset program, thereby achieving workpiece 200 positioning and a series of automated processes such as film supply, film pulling, film topping, film cutting, and film laminating to complete the laminating operation. The control system may include a power supply section, a PLC controller, a touch screen, and I / O control components.

[0095] The following describes the working process of the film applicator 100 in some embodiments.

[0096] Before applying the film, the workpiece 200 (such as a battery module) to be filmed can be placed on the workpiece positioning mechanism 30 manually or by a loading robot. The workpiece positioning mechanism 30 positions the workpiece 200 to maintain it in a horizontal position suitable for film application. Optionally, the film application machine 100 also includes a material detection module, which detects whether a workpiece 200 is placed on the workpiece positioning mechanism 30. When the material detection module detects that there is no workpiece 200 on the workpiece positioning mechanism 30, the loading robot can grab the workpiece 200, take a picture, and send it into the workpiece positioning mechanism 30. Then, the loading robot returns to its initial position.

[0097] After the feeding robot returns to its initial position, it sends a film preparation signal to the film supply mechanism 50. The film pulling mechanism 60, the film applying mechanism 40, and the moving module 20 are already waiting at the film receiving position. Upon receiving the film preparation signal, the film supply mechanism 50 delivers the protective film 301 to the film pulling mechanism 60. The film pulling mechanism 60 clamps the film head of the protective film 301 delivered by the film supply mechanism 50 and stretches it to a preset position along the first direction. Then, the film applying mechanism 40, driven by the moving module 20, moves to the first station above the top film mechanism 70. The top film mechanism 70 pushes out to cooperate with the film applying mechanism 40 to clamp the film head. Then, the film pulling mechanism 60 releases the film head and moves back to the starting position. Next, the film applying mechanism 40 continues to move downward to the second station. The film suction component 41 of the film applying mechanism 40 generates negative pressure to adsorb the protective film 301. Then, the film cutting mechanism 80 moves to move the protective film 301 away from the top film mechanism 70. After the end is cut, the film cutting mechanism 80 immediately returns to its initial state after the action is completed; after the protective film 301 is cut, the top film mechanism 70 retracts; after the moving module 20 receives the signal that it can enter the film application position, the moving module 20 drives the film application mechanism 40 to move to the third working position above the workpiece positioning mechanism 30. At this time, the film suction assembly 41 can be located about 2 mm above the workpiece 200. The negative pressure of the film suction assembly 41 is released to release the protective film 301 onto the surface of the workpiece 200. The elastic film pressing assembly 42 presses against one end of the protective film 301 and moves back and forth along the first direction on the surface of the workpiece 200 under the drive of the moving module 20, so that the protective film 301 can adhere to the surface of the workpiece 200.

[0098] After the film is applied, the workpiece 200 can be removed from the workpiece positioning mechanism 30 by manual labor or by a material handling robot, and then the workpiece 200 can be transferred to the next work station for subsequent operations.

[0099] The technical solution of this application, through the cooperation of the workpiece positioning mechanism 30, the film supply mechanism 50, the film pulling mechanism 60, the film lifting mechanism 70, the film cutting mechanism 80, the film applying mechanism 40, and the moving module 20, can achieve workpiece 200 positioning and realize a series of automated operations such as film supply, film pulling, film lifting, film cutting, and film applying, thereby achieving automated film application to the surface of workpiece 200. Furthermore, because the elastic film pressing component 42 has a certain degree of elasticity, it can adaptively adjust its elastic floating during the pressing process onto the surface of workpiece 200. Thus, even if the film applying mechanism 40 wears, it can adaptively compensate through its own elasticity, thereby eliminating bubbles and wrinkles caused by dimensional tolerances. The film applying machine 100 of this solution can achieve automated film application, reduce the generation of film bubbles and wrinkles, improve film yield, reduce rework rate, and thus improve production efficiency and save costs.

[0100] like Figure 4 and Figure 5As shown, in some embodiments, the film supply mechanism 50 includes a base 51 disposed on the machine base 10, and a film preparation assembly 52 and a film pulling assembly 53 disposed on the base 51. The film preparation assembly 52 is used to provide a protective film 301 and convey it toward the film pulling mechanism 60; the film pulling assembly 53 is used to clamp the protective film 301 and pull it toward the side away from the film pulling mechanism 60 after the film pulling mechanism 60 stretches the protective film 301 to a preset position, so as to tension the protective film 301 to be cut.

[0101] In this embodiment, the film supply mechanism 50 can be mounted on the machine base 10 via the base 51. When a film preparation signal is received, the film preparation assembly 52 delivers the protective film 301 to the film pulling mechanism 60. The film pulling mechanism 60 stretches the protective film 301 along the first direction to a preset position. Then, the top film mechanism 70 and the film application mechanism 40 cooperate to clamp the film head of the protective film 301. The film suction assembly 41 of the film application mechanism 40 generates negative pressure to adsorb the protective film 301. Next, the film pulling assembly 53 can pull the end of the protective film 301 away from the film head towards the side away from the film pulling mechanism 60, so that the protective film 301 is taut, which can ensure the accuracy of the protective film 301 in the length direction. Furthermore, the taut protective film 301 is also more conducive to the subsequent film cutting mechanism 80 cutting the protective film 301 to ensure the flatness of the cut. Through the cooperation of the above-mentioned multiple mechanisms, the protective film 301 can achieve vertical, horizontal, front and back positioning and shaping, giving the protective film 301 high dimensional accuracy, which helps to improve the accuracy of film application and further reduce the generation of bubbles and wrinkles in the film application.

[0102] like Figure 5 As shown, in some embodiments, the film preparation assembly 52 includes a material rack 521, a film winding roller 522, a release liner peeling roller 523, and a film feeding roller 524. The material rack 521 is disposed on the base 51 and is used to hold the roll film 300, which is a double-layer film having a protective film 301 and a release liner 302. A plurality of film winding rollers 522 are rotatably disposed on the base 51 and are used to wind the film material pulled from the roll film 300 and convey it in a predetermined direction. The release liner peeling roller 523 is rotatably disposed on the base 51 and is used to wind the release liner 302 to peel the release liner 302 from the protective film 301 of the film material conveyed by the film winding roller 522; the film feeding roller 524 is rotatably disposed on the base 51 and is used to convey the protective film 301 toward the film pulling mechanism 60 in a first direction.

[0103] In this embodiment, the material rack 521 is used to hold the roll film 300 and provide support for it. For example, the material rack 521 may include a roller for mounting the roll film 300 and limiting plates at both ends of the roller. The axial displacement of the roll film 300 can be limited by the limiting plates on both sides. Optionally, the distance between the two limiting plates is adjustable to accommodate roll films 300 of different widths. Optionally, one end of the roller is connected to a power component, which drives the roller to rotate to realize the unwinding and rewinding of the roll film 300. The film material of the roll film 300 is pulled out to a certain length from one end of the film head and wound around multiple winding rollers 522. The multiple winding rollers 522 tension the film material and convey it. After the film material is conveyed a certain distance, the release paper 302 is wound around the release paper peeling roller 523. As the release paper peeling roller 523 rotates continuously, the release paper 302 can be peeled off from the protective film 301. The peeled release paper 302 is then wound back onto the release paper peeling roller 523 for recycling, while the protective film 301 continues to be conveyed downstream via the film feeding roller 524. The film can be pre-fed towards the film pulling mechanism 60 via the film winding roller 522 and the film feeding roller 524, reducing the film pulling resistance.

[0104] like Figure 1 and Figure 6 As shown, in some embodiments, the film-pulling mechanism 60 includes a film-pulling power assembly 61, a film-clamping assembly 62, and a transmission assembly 63. The film-clamping assembly 62 is used to clamp or release the protective film 301. The film-pulling power assembly 61 is used to drive the film-clamping assembly 62 to reciprocate along a first direction. The transmission assembly 63 drives the film-pulling power assembly 61 to the release paper peeling roller 523. The power output by the film-pulling power assembly 61 is transmitted to the release paper peeling roller 523 via the transmission assembly 63 to make the release paper peeling roller 523 rotate.

[0105] In this embodiment, when film preparation is required, the film head of the protective film 301 is clamped by the film clamping assembly 62, and then the film pulling power assembly 61 drives the film clamping assembly 62 to move away from the film supply mechanism 50 along the first direction, thereby stretching the protective film 301 to a preset position. Next, after the top film mechanism 70 and the film application mechanism 40 cooperate to clamp the film head of the protective film 301, the film clamping assembly 62 can release the film head, and then the film pulling power assembly 61 drives the film clamping assembly 62 to move towards the side closer to the film supply mechanism 50 to the starting position. Since the film pulling power assembly 61 and the release paper peeling roller 523 are connected by a transmission assembly 63, when the film pulling mechanism 60 is running, the power output by the film pulling power assembly 61 can be transmitted to the release paper peeling roller 523 by the transmission assembly 63 to drive the release paper peeling roller 523 to rotate, thereby peeling the release paper 302 from the protective film 301 through the release paper peeling roller 523. In this way, the power of the film pulling mechanism 60 can drive the release paper peeling roller 523 to rotate, eliminating the need for an additional power component to drive the release paper peeling roller 523, thus reducing costs and space requirements.

[0106] The specific structure of the film-pulling power assembly 61 can vary, including but not limited to using a nut and screw mechanism, a gear and rack mechanism, a linear motor, etc., as long as it can achieve linear drive of the film clamping assembly 62. The specific structure of the transmission assembly 63 can also vary, including but not limited to using a synchronous belt drive mechanism, a sprocket drive mechanism, a gear set drive mechanism, etc., as long as it can transmit the power output from the film-pulling power assembly 61 to the release paper peeling roller 523 to drive the release paper peeling roller 523 to rotate.

[0107] like Figure 4 and Figure 5 As shown, in some embodiments, the film-pulling assembly 53 includes a film-pulling clamping module 531 and a film-pulling drive 532. The base 51 is provided with a slide rail 511 extending along a first direction. The film-pulling clamping module 531 is slidably connected to the slide rail 511. The film-pulling clamping module 531 is used to clamp or release the protective film 301. The film-pulling drive 532 drives the film-pulling clamping module 531 to reciprocate along the slide rail 511.

[0108] In this embodiment, a slide rail 511 extending along a first direction is provided on the base 51. The sliding cooperation between the film-pulling clamping module 531 and the slide rail 511 improves the movement accuracy of the film-pulling clamping module 531 in the first direction, thereby ensuring the accuracy of subsequent film cutting. After the top film mechanism 70 and the film-applying mechanism 40 clamp the film head of the protective film 301, the film-pulling clamping module 531 clamps the end of the protective film 301 away from the top film mechanism 70. Then, the film-pulling drive component 532 drives the film-pulling clamping module 531 to pull it along the first direction away from the film-pulling mechanism 60, thereby tensioning the protective film 301 to ensure the accuracy of the protective film 301 in the length direction and to facilitate film cutting by the film-cutting mechanism 80. After film cutting is completed, the film-pulling clamping module 531 releases the protective film 301 so that the protective film 301 can continue to be conveyed forward. The film-pulling drive component 532 includes, but is not limited to, cylinders, hydraulic cylinders, electric push rods, or other linear drive mechanisms. Optionally, the film-pulling drive 532 is a cylinder, and the piston rod of the cylinder is connected to the film-pulling clamping module 531. The piston rod extends and retracts to drive the film-pulling clamping module 531 to reciprocate along the first direction.

[0109] For example, such as Figure 4 As shown, in some embodiments, the film-pulling clamping module 531 includes a support frame 5311, a base plate 5312, a pressure plate 5313, and a film-pulling lifting drive 5314. The support frame 5311 is slidably mounted on the base 51 along a first direction. The base plate 5312 and the film-pulling lifting drive 5314 are both mounted on the support frame 5311. The pressure plate 5313 is vertically and vertically positioned above the base plate 5312. The film-pulling lifting drive 5314 drives and connects to the pressure plate 5313. A film feeding channel for the protective film 301 to pass through is formed between the pressure plate 5313 and the base plate 5312. The film-pulling drive 532 is driven and connected to the support frame 5311 to drive the support frame 5311 to reciprocate along the first direction.

[0110] In this embodiment, when the film-pulling mechanism 60 pulls the film, a film-feeding channel is formed between the pressure plate 5313 and the bottom plate 5312, which does not affect the normal delivery of the protective film 301. After the film is pulled into place, the top film mechanism 70 and the film-applying mechanism 40 clamp the film head, and the film-pulling lifting drive 5314 drives the pressure plate 5313 to press down. The pressure plate 5313 and the bottom plate 5312 cooperate to clamp the end of the protective film 301 away from the film head. Then, the film-pulling drive 532 can drive the support frame 5311 to move away from the film-pulling mechanism 60, thereby realizing the film-pulling action. The film-pulling lifting drive 5314 includes, but is not limited to, using a cylinder, a hydraulic cylinder, an electric push rod, or other linear drive mechanisms. Optionally, the film-pulling lifting drive 5314 uses a cylinder, and the piston rod of the cylinder is connected to the pressure plate 5313. The extension and retraction of the piston rod drives the pressure plate 5313 to move up and down.

[0111] like Figure 5 As shown, in some embodiments, the film supply mechanism 50 further includes a film pushing assembly 54 disposed on the base 51. The film pushing assembly 54 has a retractable drive rod, which is used to extend after the film cutting mechanism 80 cuts the protective film 301 to push open the roll film 300.

[0112] In this embodiment, the film pushing assembly 54 includes, but is not limited to, an electric push rod, a cylinder, or other mechanisms with a retractable drive rod. After the film cutting mechanism 80 cuts the protective film 301, the drive rod of the film pushing assembly 54 extends to push the roll film 300 open, completely separating the roll film 300 from the cut protective film 301 to avoid interference with the subsequent adsorption of the protective film 301. Once the roll film 300 is pushed open, the drive rod of the film pushing assembly 54 immediately retracts to its original position, preparing for the next operation.

[0113] like Figure 5 As shown, in some embodiments, the film supply mechanism 50 further includes a first material detection sensor 55 disposed on the base 51, the first material detection sensor 55 being used to detect whether the roll film 300 on the film preparation assembly 52 is used up.

[0114] In this embodiment, the first material detection sensor 55 is positioned close to the film winding roller 522. The sensor detects whether film material pulled from the roll film 300 is wound on the film winding roller 522 to determine if the roll film 300 is used up. Upon receiving a signal from the first material detection sensor 55 indicating that the roll film 300 is used up, the control system of the laminator 100 can control an alarm device to issue an alarm signal, reminding the operator to replenish the roll film 300 in a timely manner. The first material detection sensor 55 may include, but is not limited to, photoelectric sensors, mechanical microswitches, etc.

[0115] like Figure 5 As shown, in some embodiments, the film supply mechanism 50 further includes a second material detection sensor 56 disposed on the base 51, which is used to detect whether the release paper 302 on the film preparation assembly 52 is broken.

[0116] In this embodiment, the second material detection sensor 56 is positioned close to the release paper peeling roller 523 to detect whether the release paper 302 on the release paper peeling roller 523 is broken. Upon receiving a release paper 302 breakage signal from the second material detection sensor 56, the control system of the laminating machine 100 can control an alarm device to issue an alarm signal to remind the operator to perform timely maintenance. The second material detection sensor 56 may include, but is not limited to, photoelectric sensors, mechanical microswitches, etc.

[0117] like Figure 1 and Figure 7As shown, in some embodiments, the top film mechanism 70 includes a transverse module 71 disposed on the machine base 10, a top film drive member 72 drivenly connected to the transverse module 71, and a top film member 73 drivenly connected to the top film drive member 72. The transverse module 71 is used to drive the top film drive member 72 and the top film member 73 to reciprocate along a first direction, and the top film drive member 72 is used to drive the top film member 73 to rise and fall.

[0118] In this embodiment, the top film drive component 72 and the top film component 73 are driven to move along the first direction by the transverse module 71, making their positions adjustable in the first direction. In practical applications, the film stretching mechanism 60 can stretch the protective film 301 to a suitable position along the first direction according to the required film length for the actual workpiece 200. Correspondingly, the transverse module 71 can drive the top film drive component 72 and the top film component 73 to move along the first direction to a position compatible with the film stretching mechanism 60 for film application. This makes the positions of the top film drive component 72 and the top film component 73 more flexible in the first direction, thus better adapting to the film application of different workpieces 200 and broadening the application range. The transverse module 71 includes, but is not limited to, using a nut screw mechanism, gear rack mechanism, synchronous belt mechanism, or other linear drive mechanism to drive the top film drive component 72 to perform reciprocating linear motion along the first direction. The top film drive component 72 is used to drive the top film component 73 to adjust its height along a third direction. For example, when the top film is not needed, the top film member 73 is in a low position to avoid interfering with the film pulling mechanism 60. When the film is pulled into place, the top film drive member 72 drives the top film member 73 to push upwards, so that the top film member 73 abuts against the bottom side of the protective film 301. The film head of the protective film 301 can be clamped by the cooperation of the top film member 73 and the film application mechanism 40. The top film drive member 72 includes, but is not limited to, using a cylinder, electric push rod or other linear drive mechanism to drive the top film member 73 to rise and fall.

[0119] like Figure 7 As shown, in some embodiments, the top membrane mechanism 70 further includes a flexible cover 74, which at least partially covers the periphery of the transverse module 71 and is capable of telescoping along a first direction. The flexible cover 74 provides protection for the transverse module 71, and its telescoping capability along the first direction does not interfere with the movement of the top membrane drive member 72 on the transverse module 71. The flexible cover 74 may be made of a flexible material such as rubber or silicone. The flexible cover 74 may have multiple pleats arranged along the first direction for better telescoping effect.

[0120] For example, the transverse module 71 may include a transverse drive motor, a lead screw driven by the transverse drive motor, and a nut seat sleeved on the lead screw. The top film drive component 72 is connected to the nut seat. The flexible cover 74 may include a first cover and a second cover, which are located on both sides of the nut seat and cover the periphery of the lead screw. When the transverse drive motor drives the lead screw to rotate, it can drive the nut seat and the top film drive component 72 to move along the lead screw. At the same time, the first cover and the second cover can extend or contract with the movement of the nut seat without interfering with the movement of the nut seat along the lead screw, thus preventing interference with the movement of the top film drive component 72 on the transverse module 71. Furthermore, the flexible cover 74 can also prevent dust and water from entering the lead screw, thereby extending the service life of the transverse module 71.

[0121] like Figure 1 and Figure 8 As shown, in some embodiments, the film cutting mechanism 80 includes a cutter holder 81, a cutter assembly 82 and a film cutting drive 83 disposed on the cutter holder 81. The cutter assembly 82 includes an upper cutter 821 and a lower cutter 822 that are movable relative to each other; the film cutting drive 83 is drivenly connected to the cutter assembly 82 and is used to drive the upper cutter 821 and the lower cutter 822 to move closer to or further away from each other.

[0122] In this embodiment, when film cutting is not required, the upper cutter 821 and the lower cutter 822 are far apart, and the protective film 301 output by the film supply mechanism 50 can pass between the upper cutter 821 and the lower cutter 822 and be conveyed forward normally. When film cutting is required, the film cutting drive 83 drives the upper cutter 821 and the lower cutter 822 to move closer together to generate a shearing force on the protective film 301, thereby cutting the protective film 301.

[0123] The film-cutting drive unit 83 is driven to connect with the cutter assembly 82, and is used to drive the upper cutter 821 and the lower cutter 822 to move closer or further apart. This can be understood as requiring at least one of the upper cutter 821 and the lower cutter 822 to be driven to connect with the film-cutting drive unit 83. For example, the film-cutting drive unit 83 can drive the upper cutter 821 to move up and down, while the lower cutter 822 remains stationary. Alternatively, the film-cutting drive unit 83 can drive the lower cutter 822 to move up and down, while the upper cutter 821 remains stationary. Yet another example is that the film-cutting drive unit 83 can drive both the upper cutter 821 and the lower cutter 822 simultaneously, allowing both the upper and lower cutters 821 to move up and down.

[0124] For example, such as Figure 8As shown, the upper cutter 821 and the lower cutter 822 are slidably mounted on the cutter holder 81. The film cutting drive unit 83 includes an upper cutter drive unit 831 and a lower cutter drive unit 832. The upper cutter drive unit 831 is driven to the upper cutter 821, and the lower cutter drive unit 832 is driven to the lower cutter 822. The upper cutter drive unit 831 is used to drive the upper cutter 821 to move up and down, and the lower cutter drive unit 832 is used to drive the lower cutter 822 to move up and down.

[0125] To enhance the safety of the film cutting mechanism 80, in some embodiments, the film cutting mechanism 80 further includes a safety door (not shown). The safety door is equipped with a safety monitoring switch, which is used to monitor the status of the safety door and send a feedback signal to the control system. The control system is used to prevent the film cutting mechanism 80 from operating when the safety door is in the open state.

[0126] In this embodiment, a safety monitoring switch is used to monitor the opening and closing status of the safety door in real time. When the safety monitoring switch detects that the safety door is in the open state, it sends a signal to the control system of the laminating machine 100. After receiving the signal, the control system can control the disconnection of the power supply to the film cutting mechanism 80, so that the film cutting mechanism 80 cannot operate. The safety monitoring switch includes, but is not limited to, limit switches, micro switches, etc.

[0127] To enhance the safety of the film cutting mechanism 80, in some embodiments, the film cutting mechanism 80 further includes a switching valve (not shown), which is used to turn on or off the power source of the film cutting drive 83.

[0128] In this embodiment, the switching valve can be a mechanical valve or a solenoid valve. When the switching valve is open, the power source of the film-cutting drive 83 outputs power normally, enabling the film-cutting drive 83 to drive the cutter assembly 82 to operate normally. When the switching valve is closed, the power source of the film-cutting drive 83 cannot output power, preventing the film-cutting drive 83 from driving the cutter assembly 82 to operate. For example, the film-cutting drive 83 can be a cylinder connected to an air circuit. Gas is supplied to the cylinder through the air circuit as a power source to drive the cylinder to operate. The switching valve is used to open or close the air circuit of the film-cutting drive 83. When maintenance of the cutter assembly 82 is required, the air circuit can be disconnected through the switching valve, preventing the cutter assembly 82 from operating and ensuring the safety of the operator.

[0129] To improve the safety of the film cutting mechanism 80, such as Figure 8 As shown, in some embodiments, the film cutting mechanism further includes a safety block 84 having a first position located between the upper cutter 821 and the lower cutter 822, and a second position moved out from between the upper cutter 821 and the lower cutter 822.

[0130] In this embodiment, the safety block 84 can move between a first position and a second position. For example, when maintenance of the cutter assembly 82 is required, the safety block 84 can be moved to the first position, allowing it to separate the upper cutter 821 and the lower cutter 822, preventing them from closing and ensuring operator safety. After maintenance of the cutter assembly 82 is completed, the safety block 84 can be moved to the second position, allowing the upper cutter 821 and the lower cutter 822 to close normally for film cutting operations. Optionally, the safety block 84 is rotatably or slidably connected to the base 51, allowing it to rotate or slide between the first and second positions.

[0131] To further enhance the safety of the film cutting mechanism 80, optionally, the film cutting mechanism 80 includes at least two of the following: a safety door equipped with a safety monitoring switch, a switching valve, and a safety block 84, to achieve at least two layers of protection. Optionally, the film cutting mechanism 80 simultaneously includes a safety door equipped with a safety monitoring switch, a switching valve, and a safety block 84, which can achieve three layers of protection, greatly improving the safety of the film cutting mechanism 80 and significantly enhancing the protection level for operators.

[0132] like Figure 1 As shown, in some embodiments, two sets of film-pulling mechanisms 60 are arranged opposite each other along the second direction. Each film-pulling mechanism 60 has a corresponding film-supplying mechanism 50 on one side along the first direction. A film-cutting mechanism 80 is provided between each film-pulling mechanism 60 and the corresponding film-supplying mechanism 50. A top film mechanism 70 is provided on the side of each film-pulling mechanism 60 away from the other film-pulling mechanism 60. A workpiece positioning mechanism 30 is provided between the two film-pulling mechanisms 60. The first direction intersects with the second direction.

[0133] In this embodiment, the film supply mechanism 50, film pulling mechanism 60, film topping mechanism 70, and film cutting mechanism 80 are arranged in two groups side by side along the second direction, sharing the workpiece positioning mechanism 30, the moving module 20, and the film application mechanism 40. The overall layout is compact and has high space utilization. Furthermore, while the film application mechanism 40 cooperates with the first group of film supply mechanism 50, film pulling mechanism 60, film topping mechanism 70, and film cutting mechanism 80 to perform film application, the second group of film supply mechanism 50 and film pulling mechanism 60 can simultaneously perform film preparation. After the moving module 20 drives the film application mechanism 40 to complete the film application of the previous workpiece 200, the moving module 20 can drive the film application mechanism 40 to move along the second direction to cooperate with the second group of film topping mechanism 70 and film cutting mechanism 80 to perform the film application of the next workpiece 200, thereby effectively improving production efficiency.

[0134] This application also proposes a battery production equipment, which includes a film applicator 100. The specific structure of the film applicator 100 is as described in the above embodiments. Since this battery production equipment adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
