Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

For example, the term "upper" may also be used to represent a certain attachment relationship or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in the present application can be understood according to the specific situation.

[0050] In addition, the terms "install", "set", "provide", "connect", "link" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there is an internal connection between two devices, elements or components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific situation.

[0051] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components. The specific types and structures may be the same or different, and are not used to indicate or imply the relative importance and quantity of the indicated device, element or component. Unless otherwise specified, the meaning of "a plurality" is two or more.

[0052] As mentioned in the background art, in the related art, when the film to be coated is transferred between different workstations, especially at the critical moment of workstation switching, the position of the film to be coated on the fixture is likely to shift, resulting in a position deviation, which will seriously affect the quality and accuracy of film coating.

[0053] To solve the above problems, the present application provides a film coating device, which can avoid the situation that the film to be coated cannot be adsorbed and fixed on the fixture during the process of transferring the fixture from one workstation to another, resulting in the position shift of the film to be coated on the fixture. It can not only ensure the stable position of the film to be coated during the film coating process, but also improve the processing accuracy and quality.

[0054] The technical solution of the present application will be further described below in conjunction with specific embodiments and drawings.

[0055] See Figures 1 to 5 , this embodiment provides a film coating device 1, which includes: a frame 100, a fixture 200, a transfer structure 300, a first negative pressure assembly 400, and a second negative pressure assembly 500. A plurality of workstations 110 are arranged on the frame 100, and the plurality of workstations 110 are used for processing the film to be coated with different processes; the fixture 200 is movably arranged on the frame 100, the fixture 200 is used to carry the film to be coated, and an adsorption part 210 is arranged on the fixture 200; the transfer structure 300 is movably arranged on the frame 100, and the transfer structure 300 is used to transfer the fixture 200 to different workstations 110; there are a plurality of first negative pressure assemblies 400, and the plurality of first negative pressure assemblies 400 are arranged on the frame 100 and correspond to the plurality of workstations 110. When the fixture 200 stays at any workstation 110, the first negative pressure assembly 400 is communicated with the adsorption part 210; the second negative pressure assembly 500 is arranged on the transfer structure 300, and when the fixture 200 is transferred between different workstations 110, the second negative pressure assembly 500 is communicated with the adsorption part 210.

[0056] Among them, the film to be coated can be polyethylene terephthalate film, polyethylene film, oriented polypropylene film, polyvinyl chloride film, polyimide film, mylar film, etc. In this embodiment, the film to be coated is taken as an example of mylar film for illustration.

[0057] Thus, when the fixture 200 stays at any working station 110, the first negative pressure assembly 400 on the frame 100 communicates with the adsorption portion 210 on the fixture 200 to adsorb the film to be coated carried on the fixture 200 onto the fixture 200, thereby preventing the position of the film to be coated from shifting on the fixture 200 during the processing of the film to be coated by the film coating device 1. When it is necessary to transfer the fixture 200 from one working station 110 to another by means of the transfer structure 300, the second negative pressure assembly 500 on the transfer structure 300 communicates with the adsorption portion 210 on the fixture 200 to adsorb the film to be coated on the fixture 200 during the transfer of the fixture 200, thereby preventing the film to be coated from not being adsorbed and fixed on the fixture 200 and causing the position of the film to be coated to shift on the fixture 200 during the transfer of the fixture 200 from one working station 110 to another. Thus, this embodiment can not only ensure the stable position of the film to be coated during the film coating process, improve the processing accuracy and quality, but also prevent the film to be coated from shifting or falling off during the transfer process, thereby ensuring the coherence and stability of the entire production process and improving the consistency and qualification rate of the products.

[0058] In a possible embodiment, referring to Figure 1 and Figure 6 , a plurality of working stations 110 are arranged along a first direction; the transfer structure 300 is used to drive the fixture 200 to move along the first direction and can drive the fixture 200 to move along a second direction perpendicular to the first direction; a first air passage 220 and a second air passage 230 are provided on the fixture 200, and both the first air passage 220 and the second air passage 230 communicate with the adsorption portion 210; when the fixture 200 stays at any working station 110, the first negative pressure assembly 400 is docked with the first air passage 220 along the second direction, and when the transfer structure 300 drives the fixture 200 to move away from the frame 100 along the second direction, the first negative pressure assembly 400 is separated from the first air passage 220 along the second direction, and the second negative pressure assembly 500 is docked with the second air passage 230 along the second direction.

[0059] Wherein, the first direction is the direction indicated by the arrow X in Figure 1 and the second direction is the direction indicated by the arrow Y in Figure 1 .

[0060] When the jig 200 needs to be transferred from one workstation 110 to another workstation 110, the transfer structure 300 is first used to drive the jig 200 to move away from the frame 100 in the second direction. In the process of the jig 200 moving away from the frame 100, the first air channel 220 on the jig 200 also gradually moves away from the first negative pressure component 400 on the frame 100 until the first air channel 220 is separated from the first negative pressure component 400. At the same time, the second negative pressure component 500 on the transfer structure 300 will dock with the second air channel 230 on the jig 200 in the second direction, thereby realizing seamless switching from the first negative pressure component 400 to the second negative pressure component 500, avoiding adsorption interruption as much as possible, thereby avoiding problems such as the film to be coated falling off or position displacement caused by adsorption interruption during the movement of the jig 200 in the second direction.

[0061] In a possible embodiment, a first solenoid valve is provided on the first air duct 220, and a second solenoid valve is provided on the second air duct 230. When the first air duct 220 is connected to the first negative pressure component 400, the first solenoid valve is opened and the second solenoid valve is closed. When the second air duct 230 is connected to the second negative pressure component 500, the first solenoid valve is closed and the second solenoid valve is opened.

[0062] By setting a first solenoid valve on the first air channel 220 and a second solenoid valve on the second air channel 230, when the first air channel 220 is connected with the first negative pressure component 400, the first solenoid valve is opened and the second solenoid valve is closed. When the second air channel 230 is connected with the second negative pressure component 500, the first solenoid valve is closed and the second solenoid valve is opened, thereby accurately controlling the application and switching of the adsorption force, avoiding negative pressure leakage in the first air channel 220 when the first negative pressure component 400 and the first air channel 220 are in a separated state. Similarly, it can avoid negative pressure leakage in the second air channel 230 when the second negative pressure component 500 and the second air channel 230 are in a separated state, thereby ensuring that the adsorption force of the adsorption part 210 always exists, thereby improving the adsorption stability of the adsorption part 210 on the film to be coated, avoiding problems such as the film to be coated falling off and position displacement due to interruption of the adsorption force, ensuring the continuity and stability of the coating work, and improving production quality and efficiency.

[0063] In one possible embodiment, see Figure 7 and Figure 8 The second negative pressure assembly 500 includes a mounting seat 510 and a second docking portion 520 for docking with the second airway 230 . The second docking portion 520 is floatingly mounted on the mounting seat 510 along the second direction, and the mounting seat 510 is fixedly disposed on the transfer structure 300 .

[0064] Among them, the second docking portion 520 is floatingly mounted on the mounting seat 510 along the second direction, and it can be any form of floating mounting such as spring floating mounting, airbag floating mounting, hydraulic floating mounting, ball or roller floating mounting, etc., which is not limited here.

[0065] By floatingly mounting the second docking portion 520 on the mounting seat 510 along the second direction, when the second docking portion 520 is docked with the second air passage 230, it can adaptively adjust its position to compensate for possible manufacturing errors, installation deviations or slight displacements during the movement process, so as to ensure that the second docking portion 520 and the second air passage 230 can be accurately and reliably docked, improving the stability and reliability of the system. Moreover, during the docking process, if there are certain speed or position deviations, the floatingly mounted second docking portion 520 can play a buffering role, reducing hard impacts, reducing the risk of wear and damage to the second docking portion 520 and the fixture 200, and extending the service life of the second docking portion 520 and the fixture 200. In addition, the floating mounting structure has relatively low requirements for accuracy during the assembly process, reducing the assembly difficulty of the second negative pressure assembly 500, improving the assembly efficiency, and also reducing the cost increase caused by overly high assembly accuracy requirements.

[0066] In a possible embodiment, refer to Figure 9 , the second docking portion 520 is floatingly mounted on the mounting seat 510 through an elastic member 530.

[0067] Thus, when there are installation errors, manufacturing tolerances or minor displacements during operation, the elasticity of the elastic member 530 enables the second docking portion 520 to adaptively adjust its position to ensure the accurate docking of the second docking portion 520 and the second air passage 230. For example, due to long-term use, the positions of the mounting seat 510 or the second air passage 230 are slightly deviated, and the elastic member 530 can automatically compensate for this deviation of the docking portion to maintain a good docking effect. Moreover, compared with other complex floating mounting methods, the structure of the elastic member 530 is relatively simple, easy to install and maintain, reducing costs and maintenance difficulties.

[0068] Among them, the above-mentioned elastic member 530 can be a spring, a rubber pad, a gas spring, an elastic polyurethane member, etc. In a preferred embodiment, the above-mentioned elastic member 530 is a spring.

[0069] In a possible embodiment, along the second direction, the first negative pressure assembly 400 is movably arranged on the frame 100.

[0070] By movably arranging the first negative pressure assembly 400 on the frame 100, during the process that the transfer structure 300 drives the jig 200 to move away from the frame 100 in the second direction, the first negative pressure assembly 400 can also move away from the frame 100 along with the jig 200 in the second direction until it is determined that the second negative pressure assembly 500 is completely docked and communicated with the second air passage 230. When the transfer structure 300 starts to drive the jig 200 to move in the first direction, the first negative pressure assembly 400 separates from the first air passage 220 along the second direction and resets, thus ensuring the continuity of negative pressure adsorption, avoiding the sudden interruption of negative pressure adsorption, and ensuring the stability and reliability of adsorption.

[0071] Among them, the movement of the first negative pressure assembly 400 in the second direction can be driven by any driving member such as a driving cylinder, an electric motor, a stepping motor, a servo motor, a linear motor, etc., which is not limited herein.

[0072] In a possible embodiment, referring to Figure 5 , the first negative pressure assembly 400 includes a first docking portion 410 and a first negative pressure member. The first docking portion 410 and the first negative pressure member are connected by a first one-way valve, and the first one-way valve is configured to be communicated from the first docking portion 410 to the first negative pressure member and not communicated from the first negative pressure member to the first docking portion 410;

[0073] The second negative pressure assembly 500 further includes a second negative pressure member. The second docking portion 520 and the second negative pressure member are connected by a second one-way valve, and the second one-way valve is configured to be communicated from the second docking portion 520 to the second negative pressure member and not communicated from the second negative pressure member to the second docking portion 520.

[0074] Among them, the negative pressure member can be a micro vacuum pump, a negative pressure aspirator, etc., and the one-way valve can be a spring-type one-way valve, a pneumatic one-way valve, etc., which is not limited herein.

[0075] Through the arrangement of the first one-way valve and the second one-way valve, it can effectively prevent the negative pressure from flowing back from the first negative pressure member to the first docking portion 410 and from the second negative pressure member to the second docking portion 520, ensuring the stability and reliability of the negative pressure, avoiding negative pressure loss, and thus ensuring the continuity and stability of the adsorption effect. For example, when the coating device 1 suddenly stops or there is a pressure fluctuation, the one-way valve can prevent the negative pressure from flowing back, maintain the adsorption state, and prevent the film to be coated from falling.

[0076] In a possible embodiment, the materials of the first docking portion 410 and the second docking portion 520 are both polyurethane. Polyurethane has excellent elasticity and can closely fit the surface of the adsorbed object during vacuum adsorption, filling in tiny unevenness, thereby forming a good seal, reducing the possibility of air leakage. Moreover, polyurethane has low air permeability and can better maintain the vacuum degree. In addition, polyurethane can withstand frequent adsorption and release operations, is not prone to fatigue deformation or rupture, and ensures reliable adsorption for a long time.

[0077] Of course, the materials of the first docking portion 410 and the second docking portion 520 are not limited to polyurethane. The materials of the first docking portion 410 and the second docking portion 520 can also be rubber or silicone, which should be known to those skilled in the art.

[0078] In a possible embodiment, referring to Figure 10 , a plug-in portion 310 is provided on the transfer structure 300, and a plug-in end 240 is provided on the jig 200. The plug-in portion 310 and the plug-in end 240 are plugged and matched along the second direction to position the jig 200 on the transfer structure 300.

[0079] By providing the plug-in portion 310 on the transfer structure 300 and the plug-in end 240 on the jig 200, the precise positioning of the jig 200 on the transfer structure 300 along the second direction is achieved through the cooperation of the plug-in portion 310 and the plug-in end 240, ensuring that the position of the jig 200 is accurate during movement and operation, improving the accuracy of processing or operation. Moreover, the plugging and matching method facilitates the docking and separation of the jig 200 and the transfer structure 300 in the second direction, improving the production efficiency of the film wrapping device 1.

[0080] In a possible embodiment, referring to Figure 10 , a rolling component 3101 is provided on the plug-in portion 310. The rolling component 3101 includes at least two rolling elements. When the plug-in portion 310 and the plug-in end 240 are plugged and matched, at least two rolling elements are respectively in contact with two opposite sides of the plug-in portion 310 along the first direction.

[0081] Thus, when the insertion part 310 is inserted and mated with the insertion end 240, the rolling elements contact two opposite sides of the insertion part 310 along the first direction, converting the sliding friction between the insertion part 310 and the insertion end 240 into rolling friction, reducing the friction force between the insertion part 310 and the insertion end 240, thereby reducing the wear of the insertion part 310 and the insertion end 240 during the mating process, extending the service life of the jig 200 and the transfer structure 300. Moreover, the rolling elements reduce the insertion resistance, making the insertion and mating of the insertion part 310 and the insertion end 240 smoother and easier, improving the operation efficiency. In addition, the supporting and guiding functions of the rolling elements help to maintain the relative position accuracy of the insertion part 310 and the insertion end 240 in the first direction, avoiding position deviation caused by side friction, thereby improving the accuracy and stability of the insertion and mating.

[0082] In a possible embodiment, referring to Figure 11 , the transfer structure 300 includes a fork rod 320, a plurality of forks, and a driving member connected to the fork rod 320. The plurality of forks are arranged on the fork rod 320 and extend toward the jig 200 to form the insertion part 310. The plurality of forks correspond to the plurality of workstations 110 one by one, and the driving member is used to drive the fork rod 320 to move along the arrangement direction of the plurality of workstations 110.

[0083] Among them, the driving member can be any driving member such as a driving cylinder, an electric motor, a stepping motor, a servo motor, a linear motor, etc., which is not limited herein.

[0084] By making the plurality of forks correspond to the plurality of workstations 110 one by one, accurate positioning and transfer of the jig 200 can be achieved. The driving member drives the fork rod 320 to move along the arrangement direction of the workstations 110, ensuring that the jig 200 can accurately reach the preset workstation 110, improving the accuracy and efficiency of the transfer. Moreover, the plurality of forks are simultaneously arranged on the fork rod 320 and driven by the same driving member, ensuring the synchronization and consistency of the actions of each fork. This enables the jigs 200 on the plurality of workstations 110 to be transferred simultaneously, improving the overall rhythm and coordination of the film wrapping. For example, in multiple film wrapping processes, it can ensure that each jig 200 completes the conversion between workstations 110 at the same time, ensuring the smoothness of the production process. In addition, this centralized design of the fork rod 320 and the driving member simplifies the complexity of the transfer structure 300, reduces the number and types of components, lowers the manufacturing and maintenance costs, and the layout of the fork rod 320 and the forks is compact, occupying a small space, enabling the transfer of the jigs 200 between the plurality of workstations 110 within a limited working space, and improving the space utilization rate of the production site.

[0085] Of course, the transfer structure 300 is not limited to the above form. The transfer structure 300 can also be a conveyor belt type transfer structure 300, a robotic arm type transfer structure 300, a track type transfer structure 300, a telescopic type transfer structure 300, and so on.

[0086] In a possible embodiment, referring to Figure 11 , the shift fork rod 320 includes a first shift fork rod 3201 and a second shift fork rod 3202 that are floatingly connected along the arrangement direction of the plurality of workstations 110. Shift forks are provided on both the first shift fork rod 3201 and the second shift fork rod 3202.

[0087] By floatingly connecting the first shift fork rod 3201 and the second shift fork rod 3202 along the arrangement direction of the workstations 110, it is possible to adaptively compensate for manufacturing errors, assembly deviations, or small displacements generated during operation, which helps to ensure the accurate cooperation between the shift fork and the jig 200, and improve the reliability and stability during the transfer process of the jig 200. In addition, this design of floating connection can reduce the production precision requirements of the shift fork rod 320 to a certain extent. Since the floating connection allows position adjustment and deviation compensation within a certain range, during the manufacturing process, there is no need to pursue extremely high dimensional accuracy and position accuracy. Some small manufacturing errors or assembly deviations can be self-adjusted and adapted through the floating connection. For example, if there are certain errors in the lengths or installation positions of the first shift fork rod 3201 and the second shift fork rod 3202 during the production process, due to their floating connection, they can still achieve good cooperation with the jig 200 and the transfer operation between the workstations 110 during actual work.

[0088] In a possible embodiment, referring to Figure 11 , the first shift fork rod 3201 and the second shift fork rod 3202 are connected by a connecting rod 3203. One end of the connecting rod 3203 is floatingly connected to the first shift fork rod 3201, and the other end is fixedly connected to the second shift fork rod 3202, or one end of the connecting rod 3203 is floatingly connected to the first shift fork rod 3201, and the other end is floatingly connected to the second shift fork rod 3202.

[0089] If one end of the connecting rod 3203 is floatingly connected to the first fork rod 3201 and the other end is fixedly connected to the second fork rod 3202, it can keep the second fork rod 3202 in a relatively fixed position and posture during movement, thereby providing a certain degree of stability and support for the entire transfer structure 300. At the same time, the floating connection of the first fork rod 3201 can adapt to certain deviations and changes, which helps to achieve a certain degree of self-adjustment when the force is uneven, making the overall force more balanced. For example, when a larger resistance is applied to one side of the fork, through the floating adaptation of the first fork rod 3201 and the fixed support of the second fork rod 3202, the deformation and vibration of the entire transfer structure 300 can be reduced. In addition, the fixedly connected part can enhance the connection strength between the connecting rod 3203 and the second fork rod 3202, reducing looseness and failures that may occur under heavy load or high-speed movement conditions.

[0090] If one end of the connecting rod 3203 is floatingly connected to the first fork rod 3201 and the other end is floatingly connected to the second fork rod 3202, then both ends are floating connections, enabling both the first fork rod 3201 and the second fork rod 3202 to more flexibly adapt to various complex working conditions and external interferences. Whether it is a slight change in the spacing of the workstations 110, the irregular shape of the fixture 200, or the impact and vibration during the movement process, this double floating connection can provide better self-adaptive adjustment capabilities. Moreover, the double floating connection helps to more evenly distribute the force between the first fork rod 3201 and the second fork rod 3202, avoiding stress concentration caused by a fixed connection at a certain point. In addition, since both ends of the connecting rod 3203 have a certain floating margin, the precision requirements for installation and debugging are relatively low, reducing the manufacturing and assembly difficulty of the transfer structure 300 and improving the production efficiency of the film wrapping device 1.
