Description

Technical Field

[0001] This application relates to the field of vehicle manufacturing technology, and in particular to a coating device. Background Technology

[0002] Strip-shaped body components on a vehicle generally refer to bright strips, such as window bright strips, body bright strips, and door bright strips. As important components that affect the vehicle's sense of refinement, they usually need to be covered with a protective film to ensure the quality of the body components.

[0003] In related technologies, when applying a protective film to the surface of vehicle body components, manual application is often used to apply the protective film to the surface of the vehicle body components. However, manual application is not conducive to ensuring the quality of the protective film application and has low work efficiency. Utility Model Content

[0004] In view of this, the present application aims to provide a film-coating device that can improve the efficiency of protective film application and also help ensure the quality of protective film application.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows: A coating apparatus for applying a protective film to the surface of a strip-shaped vehicle body component, comprising a base, a jig platform and a coating head disposed on the base; the jig platform is provided with a contour block for supporting the vehicle body component and a clamping mechanism for clamping and fixing the vehicle body component. The laminating head has a frame, a drive mechanism for driving the frame to slide relative to the contour block, and a laminating mechanism disposed on the frame. The laminating mechanism includes a tape mounting base, laminating rollers driven to rise and fall by the drive unit, a cutting assembly, and a negative pressure adsorption assembly. The tape mounting base is used to unwind the protective film to be applied. When the film-applying roller descends, it can slide along the frame to apply the protective film. The cutting assembly is used to cut the protective film. The negative pressure adsorption assembly is used to adsorb the protective film during cutting.

[0006] Furthermore, the clamping mechanism includes clamping units respectively provided on both sides of the contour block, and each clamping unit on each side is a plurality of units arranged at intervals along the length direction of the contour block.

[0007] Furthermore, the driving unit adopts a driving cylinder mounted on the frame; and / or, the cutting assembly includes a cutting cylinder mounted on the frame and a cutting blade driven by the cutting cylinder; and / or, the negative pressure adsorption assembly includes an adsorption cylinder mounted on the frame and a negative pressure suction cup driven by the adsorption cylinder.

[0008] Furthermore, the contour blocks are multiple ones arranged side by side on the jig platform, and the coating mechanism on the frame is multiple ones arranged in one-to-one correspondence with each of the contour blocks.

[0009] Furthermore, there are two jig platforms mounted on the machine base. Each jig platform is equipped with the contour block and the clamping mechanism, and both jig platforms can switch between a film-coating station and a part-picking / placing station within the machine base. At the film-coating station, the vehicle body component carried on the jig platform can be covered with a protective film using the film-coating mechanism. At the part-picking / placing station, the vehicle body component to be film-coated can be placed on the jig platform, or the film-coated vehicle body component can be removed.

[0010] Furthermore, the machine base is provided with a coding and inspection station, which is located between the part picking and placing station and the film coating station, and the coding and inspection station is provided with a coding mechanism and a scanning mechanism; the coding mechanism is used to print identification codes on the vehicle body components, and the scanning mechanism is used to identify and obtain the identification codes.

[0011] Furthermore, the two tooling platforms share the same pick-and-place station, and the two tooling platforms can alternately switch between the coating station and the pick-and-place station.

[0012] Furthermore, the base is provided with a transfer mechanism corresponding to the two tooling platforms respectively, and each tooling platform is set on the corresponding transfer mechanism; each tooling platform can move between the film coating station and the part picking and placing station under the drive of the corresponding transfer mechanism, and one of the tooling platforms is vertically and vertically set on the corresponding transfer mechanism through a lifting part.

[0013] Furthermore, the transplanting mechanism includes first slide rails disposed on two opposite sides, transmission mechanisms disposed on each of the first slide rails, and a first rotary drive unit connected to each of the transmission mechanisms via a drive shaft. The jig platform is mounted between the two transmission mechanisms, and under the drive of the first rotary drive unit, each of the transmission mechanisms can slide along the first slide rails, thereby moving the jig platform between the coating station and the pick-and-place station.

[0014] Furthermore, another transplanting mechanism includes second slide rails disposed on two opposite sides, a second rotary drive unit, and a transmission belt driven by the second rotary drive unit; the lifting part includes a connecting seat that slides along the second slide rails on both sides, and a lifting cylinder disposed on the connecting seat. The jig platform is connected to the lifting cylinder and is driven to lift by the lifting cylinder, and a guide mechanism is provided between the connecting seat and the jig platform.

[0015] Compared with related technologies, this application has the following advantages: (1) The coating device described in this application supports the vehicle body components through a jig platform with a contour block and a clamping mechanism, and through a frame driven by a drive mechanism and a coating mechanism set on the frame, the protective film can be applied to the surface of the vehicle body components by using coating rollers during the sliding of the coating head. This can realize the automation of the application of protective film on the surface of the vehicle body components, which helps to improve the application efficiency of protective film and is conducive to ensuring the application quality of protective film.

[0016] (2) Clamping units are provided on both sides of the contour block to ensure the clamping and fixing effect of the body components carried on the contour block. Furthermore, each clamping unit is arranged in multiple spaced intervals. The position of each clamping unit can be adjusted according to the shape of the body components, thereby improving the adaptability of the jig platform to different body components.

[0017] (3) The drive unit adopts a drive cylinder, and the cutting component adopts a cutting blade driven by the cutting cylinder. The negative pressure adsorption component adopts a negative pressure suction cup driven by the adsorption cylinder. The structure is simple, the technology is mature, and it is easy to design and implement. It is also easy to ensure the performance of the film coating mechanism.

[0018] (4) The contour blocks are arranged in a row, and the film covering mechanism is also set in a row corresponding to each contour block. Protective film can be applied to multiple body components at the same time, which helps to improve the working efficiency of the film covering device.

[0019] (5) The tooling platform is divided into two, and the two tooling platforms can switch alternately between the film coating station and the part picking and placing station. The alternating switching of the two tooling platforms between the two stations can realize the cyclic operation of applying protective film on the vehicle body components, which is conducive to improving the working efficiency of the film coating device.

[0020] (6) By setting up a marking mechanism and a scanning mechanism, it is possible to mark codes on the vehicle body components and read the printed identification codes. The marking operation on the vehicle body components can be completed before the protective film is applied, which helps to expand the function of the film covering device and improve the quality of use of the film covering device.

[0021] (7) This allows the two tooling platforms to share the same pick-and-place station, and thus allows the two tooling platforms to switch alternately between the coating station and the pick-and-place station, which can reduce the number of stations in the machine base, help reduce the overall space occupied by the coating device, and facilitate the arrangement of the device in the production site.

[0022] (8) By setting up a transfer mechanism for each tooling platform, each tooling platform can move between the film coating station and the pick-and-place station under the drive of the corresponding transfer mechanism. At the same time, one tooling platform can be raised and lowered on the corresponding transfer mechanism, which can realize the alternating switching of the two tooling platforms between the film coating station and the pick-and-place station, which helps to reduce the overall space occupied by the film coating device.

[0023] (9) The transplanting mechanism includes a first slide rail, a transmission mechanism set on the first slide rail, and a first rotary drive unit connected to each transmission mechanism via a transmission shaft. Under the drive of the first rotary drive unit, the tooling platform is moved by the transmission mechanism. This enables the tooling platform to move while the relatively arranged first slide rail provides better support for the tooling platform, which helps to improve the stability of the protective film application work.

[0024] (10) By setting a connecting seat and using a lifting cylinder to drive the jig platform to rise and fall, and by setting a guide mechanism between the jig platform and the connecting seat, the structure is simple and easy to design and implement, and the smoothness of the jig platform's lifting movement can also be guaranteed.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0031] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0032] The embodiments of this application provide a film coating device for applying a protective film 10 to the surface of a strip-shaped body component 9, such as a bright stripe, on a vehicle. The innovative design of this film coating device helps to improve the application efficiency of the protective film 10 and ensure the application quality of the protective film 10.

[0033] In related technologies, a protective film 10 is typically applied to the surface of the vehicle body component 9 to effectively prevent surface damage and ensure the quality of the vehicle body component 9. However, applying the protective film 10 to the vehicle body component 9 is usually done manually, which results in low work efficiency. Furthermore, the application quality of the protective film 10 is easily affected by the worker's skill level and the application method, leading to inconsistencies and compromising the overall quality of the protective film 10 application.

[0034] In view of this, in order to overcome the shortcomings of the related technology, the coating device of this embodiment combines... Figures 1 to 10 As shown, the overall design includes a base 1, a jig platform 2 and a coating head 3 mounted on the base 1. The jig platform 2 is equipped with a contour block 201 for supporting the vehicle body component 9, and a clamping mechanism 202 for clamping and fixing the vehicle body component 9. Combined with... Figures 11 to 14 As shown, the laminating head 3 has a frame 301, a drive mechanism 302 for driving the frame 301 to slide relative to the contour block 201, and a laminating mechanism 303 provided on the frame 301. The laminating mechanism 303 includes a tape mounting base 3031, a laminating roller 3033 driven to rise and fall by the drive unit 3032, a cutting assembly 3034, and a negative pressure adsorption assembly 3035.

[0035] The tape mounting base 3031 is used to unload the protective film 10 to be applied, the film applying roller 3033 can slide and apply the protective film 10 along the frame 301 when it descends, the cutting component 3034 is used to cut the protective film 10, and the negative pressure adsorption component 3035 is used to adsorb the protective film 10 when cutting.

[0036] Thus, by setting up a jig platform 2 with a contour block 201 and a clamping mechanism 202 to support the body component 9, and by setting up a frame 301 that is driven to slide by a drive mechanism 302, and a film-coating mechanism 303 set on the frame 301, the protective film 10 can be applied to the surface of the body component 9 by using the film-coating roller 3033 during the sliding of the film-coating head 3.

[0037] Specifically, when applying the protective film 10 to the surface of the vehicle body component 9 using the film-coating roller 3033, firstly, the film-coating roller 3033 is driven by the drive unit 3032 to press against the surface of the vehicle body component 9. Secondly, the tape mounting seat 3031 unwinds the protective film 10. Simultaneously, the drive structure causes the film-coating mechanism 303 to slide along the length x direction of the vehicle body component 9 until the protective film 10 is applied to the surface of the vehicle body component 9. Then, the tape mounting seat 3031 stops unwinding the protective film 10, and the negative pressure adsorption assembly 3035 adsorbs the protective film 10. Finally, the cutting assembly 3034 cuts the protective film 10. This automates the application of the protective film 10 to the surface of the vehicle body component 9, improving the application efficiency and ensuring the application quality of the protective film 10.

[0038] Based on the above overview, it can be understood that the drive mechanism 302 causing the frame 301 to slide relative to the contour block 201 means that the drive mechanism 302 causes the frame 301 to move along the length direction x of the contour block 201, that is, along the length direction x of the body component 9. It is worth noting that in specific implementation, the drive mechanism 302 is located on the top of the base 1, and a through hole 101 is opened on the top of the frame 301 along the length direction x of the contour block 201. The frame 301 is connected to the movable end of the drive mechanism 302 via the mounting plate 8.

[0039] In detail, the drive mechanism 302 can be a cylinder, an electric push rod, or a screw and nut mechanism driven by a motor. When using the drive components described above as the drive mechanism 302, the specific specifications, style, and installation method of the drive mechanism 302 can be based on existing designs. In this embodiment, taking an electric push rod as the drive mechanism 302 as an example, during installation, the base of the electric push rod is fixed to the top of the base 1, and the push rod of the electric push rod is fixed to the mounting plate 8. Thus, with the extension and retraction of the push rod, the coating mechanism 303 can be driven to slide back and forth along the length x of the contour block 201.

[0040] In some of the exemplary implementations, combined with Figure 9 and Figure 10 As shown, the clamping mechanism 202 includes clamping units 2021 respectively provided on both sides of the contour block 201, and each clamping unit 2021 is a plurality of units arranged at intervals along the length x direction of the contour block 201.

[0041] Therefore, by providing clamping units 2021 on both sides of the contour block 201, the clamping and fixing effect of the body component 9 supported on the contour block 201 can be guaranteed. Furthermore, each side clamping unit 2021 is arranged in multiple spaced intervals, and the position of each clamping unit 2021 can be adjusted according to the shape adaptability of the body component 9, thereby improving the adaptability of the jig platform 2 to different body components 9.

[0042] It is worth noting that the clamping unit 2021 typically includes a clamping cylinder and a clamping block connected to the cylinder rod. The clamping cylinder can be fixed to the jig platform 2 by bolts. At the same time, multiple fixing points can be designed on the jig platform 2 to adjust the position of the clamping cylinder according to the shape of the body component 9.

[0043] In specific implementation, two parallel contouring grooves 2011 can be formed on the contouring block 201 along its length x, thus creating a protrusion 2012 between the two contouring grooves 2011. With this configuration, the bottom surface of the body component 9 can be placed within the contouring groove 2011, allowing the sidewall of the body component 9 to abut against the protrusion 2012. At this time, the clamping unit 2021 on one side of the contouring block 201 cooperates with the protrusion 2012 to clamp one body component 9. Therefore, two body components 9 can be placed on the same contouring block 201. Consequently, the coating mechanism 303 can simultaneously coat two body components 9 on one contouring block 201, further improving the efficiency of the protective film 10 application.

[0044] In some of the exemplary implementations, combined with Figure 2 and Figure 5 As shown, the drive unit 3032 adopts a drive cylinder 30321 mounted on the frame 301. The drive unit 3032 adopts a drive cylinder 30321, which has a simple structure, mature technology, is easy to design and implement, and also helps to ensure the performance of the coating mechanism 303.

[0045] It is worth noting that, in specific implementation, the cylinder body of the drive cylinder 30321 is connected to the frame 301, and a support plate 30322 is provided on the cylinder rod of the drive cylinder 30321. The connection between the coating roller 3033 and the drive unit 3032 is achieved through the support plate 30322. This arrangement facilitates the installation of the coating roller 3033 on the frame 301.

[0046] In some of the exemplary implementations, combined with Figure 11 and Figure 12 As shown, the cutting assembly 3034 includes a cutting cylinder 30341 mounted on the frame 301 and a cutting blade 30342 driven by the cutting cylinder 30341. The cutting assembly 3034 employs a cutting blade 30342 driven by the cutting cylinder 30341, resulting in a simple structure, mature technology, and ease of design and implementation.

[0047] It is understandable that, in order to facilitate the cutting of the protective film 10 by the cutting blade 30342, the cutting end of the cutting blade 30342 is set to be serrated in this embodiment. With this setting, when the cutting cylinder 30341 drives the cutting blade 30342 to contact the protective film 10, the cutting blade 30342 with the serrated cutting end can easily pierce the protective film 10, thereby facilitating the cutting of the protective film 10.

[0048] In some of the exemplary implementations, the combination continues Figure 11 and Figure 12As shown, the negative pressure adsorption assembly 3035 includes an adsorption cylinder 30351 mounted on a frame 301, and a negative pressure suction cup 30352 driven by the adsorption cylinder 30351. This results in a simple structure for the negative pressure adsorption assembly 3035, which is beneficial for design and implementation. In practice, the cylinder body of the adsorption cylinder 30351 can be fixed to the support plate 30322.

[0049] It is worth noting that, in order for the negative pressure adsorption component 3035 to adsorb the protective film 10, the negative pressure suction cup 30352 is connected to a negative pressure device, so that when the adsorption cylinder 30351 drives the negative pressure suction cup 30352 to come into contact with the protective film 10, the negative pressure suction cup 30352 can be adsorbed onto the protective film 10 under the action of the negative pressure device.

[0050] Based on the above overall introduction, in this embodiment, the negative pressure adsorption component 3035 is preferably located between the film coating roller 3033 and the cutting component 3034, and the film coating roller 3033, the negative pressure adsorption component 3035 and the cutting component 3034 are arranged sequentially along the film coating direction. With this arrangement, after the film coating is completed on the surface of the vehicle body component 9, the negative pressure adsorption component 3035 adsorbs the protective film 10, which makes it easier to tighten the protective film 10 between the negative pressure suction cup 30352 and the vehicle body component 9, thereby facilitating the cutting blade 30342 to cut the protective film 10.

[0051] In some of the exemplary implementations, combined with Figure 3 , Figure 6 and Figure 7 As shown, there are multiple contour blocks 201 arranged side by side on the tooling platform 2, and multiple coating mechanisms 303 on the frame 301 are arranged in a one-to-one correspondence with each contour block 201.

[0052] As a result, the contour blocks 201 are arranged in multiple rows, and the film covering mechanism 303 is also arranged in multiple ways corresponding to each contour block 201, so that protective film 10 can be applied to multiple body components 9 at the same time, which helps to improve the working efficiency of the film covering device.

[0053] It is worth noting that in this embodiment, two contour blocks 201 are arranged side by side on the jig platform 2, that is, two contour blocks 201 are arranged along the width direction of the jig platform 2. Correspondingly, two sets of film-coating mechanisms 303 are arranged on the frame 301, that is, two sets of tape mounting seats 3031, film-coating rollers 3033, cutting components 3034 and negative pressure adsorption components 3035 are respectively arranged on both sides of the frame 301. This arrangement makes it easier for the drive mechanism 302 to drive the frame 301 to move once, so as to apply the protective film 10 to the body component 9 on the two contour blocks 201, which is conducive to further improving the efficiency of the protective film 10 application work.

[0054] In some of the exemplary implementations, combined with Figures 6 to 8 As shown, there are two jig platforms 2 mounted on the machine base 1. Each jig platform 2 is equipped with a contour block 201 and a clamping mechanism 202, and both jig platforms 2 can switch between the film coating station S1 and the part pick-and-place station S2 in the machine base 1. At the film coating station S1, the car body component 9 carried on the jig platform 2 can be covered with a protective film 10 by the film coating mechanism 303; at the part pick-and-place station S2, the car body component 9 to be coated can be placed on the jig platform 2, or the coated car body component 9 can be removed.

[0055] Therefore, by having two jig platforms 2, and by enabling the two jig platforms 2 to alternately switch between the film coating station S1 and the part picking and placing station S2, the cyclical operation of applying the protective film 10 to the body component 9 can be achieved by using the alternating switching of the two jig platforms 2 between the two stations, which is beneficial to improving the working efficiency of the film coating device.

[0056] In some of the exemplary implementations, combined with Figures 4 to 8 As shown, the two jig platforms 2 share the same pick-and-place station S2, and the two jig platforms 2 can alternately switch between the coating station S1 and the pick-and-place station S2.

[0057] Therefore, by having the two jig platforms 2 share the same pick-and-place station S2, and thus allowing the two jig platforms 2 to alternately switch between the coating station S1 and the pick-and-place station S2, the number of stations in the machine base 1 can be reduced, which helps to reduce the overall space occupied by the coating device and facilitates the arrangement of the device in the production site.

[0058] It is understandable that, in addition to having the two jig platforms 2 share a single pick-and-place station S2, it is also possible to set up separate pick-and-place stations S2 for each jig platform 2. When setting up two pick-and-place stations S2, the two pick-and-place stations S2 can be located on both sides of the machine base 1, which means that the two pick-and-place stations S2 are located on both sides of the coating machine head 3.

[0059] In some of the exemplary implementations, combined with Figure 1 and Figure 4 As shown, the machine base 1 is equipped with a coding and inspection station S3, which is located between the part picking and placing station S2 and the film coating station S1. The coding and inspection station S3 is equipped with a coding mechanism 4 and a barcode scanning mechanism 5. The coding mechanism 4 is used to print identification codes on the body component 9, and the barcode scanning mechanism 5 is used to identify and obtain the identification codes.

[0060] Therefore, by setting up a marking mechanism and a barcode scanning mechanism 5, it is possible to mark codes on the vehicle body component 9 and read the printed identification codes. The marking operation on the vehicle body component 9 can be completed before the protective film 10 is applied, which helps to expand the function of the film covering device and improve the quality of use of the film covering device.

[0061] It is worth noting that the coding mechanism 4 can use existing laser coding equipment, and the scanning mechanism 5 can use existing scanning equipment. Furthermore, the coding mechanism 4 and the scanning mechanism 5 can be fixedly installed on the top of the base 1 so that the coding mechanism 4 and the scanning mechanism 5 do not affect the operation of the jig platform 2 and the coating mechanism 303.

[0062] In some of the exemplary implementations, combined with Figures 6 to 8 As shown, the base 1 is provided with transfer mechanisms 6 corresponding to the two tooling platforms 2 respectively, and each tooling platform 2 is set on the corresponding transfer mechanism 6. Under the drive of the corresponding transfer mechanism 6, each tooling platform 2 can move between the film coating station S1 and the part picking and placing station S2, and one of the tooling platforms 2 can be raised and lowered on the corresponding transfer mechanism 6 via the lifting part 7.

[0063] Therefore, by setting transfer mechanisms 6 for each tooling platform 2, each tooling platform 2 can move between the film coating station S1 and the part picking and placing station S2 under the drive of the corresponding transfer mechanism 6, so as to effectively improve the working continuity of the film coating mechanism 303 and thus effectively improve the film coating efficiency of the protective film 10.

[0064] At the same time, it allows one of the tooling platforms 2 to be raised and lowered on the corresponding transfer mechanism 6, enabling the two tooling platforms 2 to alternate between the coating station S1 and the pick-and-place station S2, which helps to reduce the floor space occupied by the coating device, thereby helping to reduce the overall space occupied by the coating device.

[0065] In some exemplary embodiments, one transfer mechanism 6 includes first slide rails 601a disposed on two opposite sides, transmission mechanisms 602 disposed on each of the first slide rails 601a, and a first rotary drive unit 604a connected to each of the transmission mechanisms 602 via a drive shaft 603. A fixture platform 2 is mounted between the two transmission mechanisms 602, and driven by the first rotary drive unit 604a, the transmission mechanisms 602 can slide along the first slide rails 601a, moving the fixture platform 2 between the coating station S1 and the pick-and-place station S2. Another transfer mechanism includes second slide rails 601b disposed on two opposite sides, a second rotary drive unit 604b, and a transmission belt 605 driven by the second rotary drive unit 604b.

[0066] Thus, by including a first slide rail 601a, a transmission mechanism 602 mounted on the first slide rail 601a, and a first rotary drive unit 604a connected to the transmission mechanism 602 via a transmission shaft 603, and by driving the first rotary drive unit 604a, the tooling platform 2 is moved via the transmission mechanism 602, thereby enabling the tooling platform 2 to move.

[0067] Meanwhile, the relatively arranged first slide rail 601a can provide better support for the jig platform 2, which helps to improve the stability of the protective film 10 application.

[0068] Based on the above overview, combined with Figures 6 to 8 As shown, for ease of explanation, each jig platform 2 can move between the coating station S1 and the pick-and-place station S2 under the action of its corresponding transfer mechanism 6. In this embodiment, the two jig platforms 2 are respectively referred to as the first jig platform 2a and the second jig platform 2b, and the two transfer mechanisms 6 are referred to as the first transfer mechanism 6a and the second transfer mechanism 6b. The first transfer mechanism 6a is set to correspond to the first jig platform 2a and is used to drive the first jig platform 2a to move between the coating station S1 and the pick-and-place station S2. The second transfer mechanism 6b is set to correspond to the second jig platform 2b and is used to drive the second jig platform 2b to move between the coating station S1 and the pick-and-place station S2.

[0069] Furthermore, the second jig platform 2b is connected to the lifting unit 7, so that the second jig platform 2b is mounted on the second transfer mechanism 6b in a height-adjustable manner. This arrangement allows the second jig platform 2b to exchange positions with the first jig platform 2a after it descends, and also allows the second jig platform 2b to rise and approach the film-coating head 3, facilitating the film-coating head 3 to apply film to the vehicle body component 9.

[0070] It is worth noting that, in order to enable the second tooling platform 2b to exchange positions with the first tooling platform 2a under the action of the second transfer mechanism 6b after it descends, in this embodiment, the length of the second tooling platform 2b is set to be less than the length of the first tooling platform 2a. That is, when the lifting part 7 drives the second tooling platform 2b to descend, it can pass under the first tooling platform 2a under the action of the second transfer mechanism 6b, thereby realizing the exchange of positions between the two tooling platforms 2.

[0071] It is understood that, specifically, the first transfer mechanism 6a includes the first slide rail 601a, the transmission mechanism 602, the transmission shaft 603, and the first rotary drive unit 604a as described above. The transmission mechanism 602 of the first transfer mechanism 6a can, for example, adopt a ball screw structure 6021 mounted on the first slide rail 601a. ​​The nut slider 6022 on the ball screw structure 6021 is connected to the first jig platform 2a to drive the jig platform 2 to move linearly and between the film coating station S1 and the part picking and placing station S2.

[0072] It is worth noting that, for the convenience of arranging the first transplanting mechanism 6a, the drive shaft 603 is set perpendicular to the first slide rail 601a. ​​In this case, one end of the ball screw in the ball screw structure 6021 can be connected to the drive shaft 603 through bevel gear meshing to realize the conversion of the power transmission direction. The first rotary drive unit 604a can be a motor, and the specific type and installation method of the motor can refer to the existing settings.

[0073] Based on the above description, in detail, the second transplanting mechanism 6b includes the second slide rail 601b, the second rotary drive unit 604b, and the transmission belt 605, as described above. Similar to the first rotary drive unit 604a, the second rotary drive unit 604b is also configured as a motor. The second transplanting mechanism 6b also includes a drive shaft seat 6051, which is mounted on the base 1 so that the transmission belt 605 can be fitted onto the drive shaft seat 6051 and the output end of the second rotary drive unit 604b, thereby driving the second rotary drive unit 604b to rotate the transmission belt 605.

[0074] Furthermore, the conveying direction of the transmission belt 605 is set parallel to the second slide rail 601b, that is, the transmission belt 605 is set perpendicular to the second tooling platform 2b. By connecting the transmission belt 605 to the lifting part 7, the lifting part 7 can be driven to move along the length direction x of the second slide rail 601b, thereby enabling the second tooling platform 2b to move along the direction of the second slide rail 601b, so as to realize the movement between the film coating station S1 and the part picking and placing station S2.

[0075] In some of the exemplary implementations, combined with Figure 8 As shown, the lifting unit 7 includes a connecting seat 701 that slides along the second slide rails 601b on both sides, and a lifting cylinder 702 disposed on the connecting seat 701. The jig platform 2 is connected to the lifting cylinder 702 and is driven to lift by the lifting cylinder 702, and a guide mechanism 703 is provided between the connecting seat 701 and the jig platform 2.

[0076] Therefore, by setting a connecting seat 701 between the two second slide rails 601b, and using a lifting cylinder 702 to drive the jig platform 2 to rise and fall, and by setting a guide mechanism 703 between the jig platform 2 and the connecting seat 701, the structure is simple, easy to design and implement, and can also ensure the smoothness of the jig platform 2's lifting movement.

[0077] In a specific implementation, the connecting seat 701 is set below the second tooling platform 2b and slidably connected to the second slide rails 601b on both sides, so that the transmission belt 605 is connected to the connecting seat 701, so that the connecting seat 701 can rotate with the second rotary drive unit 604b to drive the transmission belt 605 to move along the length x direction of the second slide rail 601b.

[0078] It is worth noting that the guide mechanism 703 can be configured as a guide rod, with one end fixed to the lower surface of the second jig platform 2b and the other end slidably passing through the connecting seat 701, and capable of relative sliding with the connecting seat 701 along its axial direction. In this embodiment, preferably, two guide rods are provided on both sides of the same lifting cylinder 702 along the width direction of the second jig platform 2b.

[0079] It is worth noting that, regarding the coating device of this embodiment, based on the above exemplary embodiments, in specific implementation, as a preferred embodiment, it still consists of... Figures 1 to 14 As shown, it may include, for example, a base 1, a jig platform 2 and a laminating head 3 mounted on the base 1. The jig platform 2 is provided with a contour block 201 for supporting the vehicle body component 9 and a clamping mechanism 202 for clamping and fixing the vehicle body component 9. The laminating head 3 has a frame 301, a drive mechanism 302 for driving the frame 301 to slide relative to the contour block 201, and a laminating mechanism 303 mounted on the frame 301. The laminating mechanism 303 includes a tape mounting seat 3031, a laminating roller 3033 driven to rise and fall by a drive unit 3032, a cutting assembly 3034, and a negative pressure adsorption assembly 3035.

[0080] The fixture platform 2 consists of two units mounted on the base 1. Each fixture platform 2 is equipped with a contour block 201 and a clamping mechanism 202. Both fixture platforms 2 can switch between a film-coating station S1 and a parts-picking / placing station S2 within the base 1. At the film-coating station S1, the vehicle body component 9 carried on the fixture platform 2 can be covered with a protective film 10 via the film-coating mechanism 303. At the parts-picking / placing station S2, the vehicle body component 9 to be coated can be placed on the fixture platform 2, or the coated vehicle body component 9 can be removed.

[0081] Furthermore, the base 1 is equipped with transfer mechanisms 6 corresponding to the two tooling platforms 2, and each tooling platform 2 is mounted on its corresponding transfer mechanism 6. Driven by its corresponding transfer mechanism 6, each tooling platform 2 can move between the film coating station S1 and the part picking and placing station S2, and one of the tooling platforms 2 can be raised and lowered on its corresponding transfer mechanism 6 via a lifting part 7.

[0082] In the preferred embodiment of the above-mentioned coating device, the specific settings and arrangements of the jig platform 2, the coating head 3, the transplanting mechanism 6, etc. can still be referred to the descriptions in the above-mentioned exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the jig platform 2, the coating head 3, and the transplanting mechanism 6, etc., can also be referred to the descriptions in the above-mentioned exemplary embodiments.

[0083] The coating device of this embodiment adopts the above design. The jig platform 2 with the contour block 201 and the clamping mechanism 202 supports the body component 9. The frame 301 driven by the drive mechanism 302 slides, and the coating mechanism 303 is set on the frame 301. During the sliding of the coating head 3, the coating roller 3033 can be used to apply the protective film 10 to the surface of the body component 9. This can realize the automation of the application of the protective film 10 to the surface of the body component 9, which helps to improve the application efficiency of the protective film 10 and ensure the application quality of the protective film 10.
