[0001] This application belongs to the field of photovoltaic module supporting tooling technology, and specifically relates to a coating mechanism and device. Background Technology

[0002] In the photovoltaic cell string processing technology, it is usually necessary to first connect and fix the welding ribbon to the cell using a polymer film to form a pre-fixed cell string, and then laminate to complete the bonding and electrical connection.

[0003] In this process, there is a problem of poor pre-fixation efficiency of battery strings. Summary of the Invention

[0005] In some embodiments, the coating assembly includes: A connector, movably connected to the mounting plate, is capable of moving relative to the mounting plate in the second direction; A coated component is connected to the connector and extends beyond the connector in the thickness direction of the mounting plate, the coated component surrounding and forming the receiving space.

[0006] In some embodiments, the coating assembly includes two connectors, which are spaced apart in the second direction; The coating component includes a first coating sub-component and a second coating sub-component. The first coating sub-component and the second coating sub-component are respectively connected to the two connecting members.

[0007] In some embodiments, the connector extends along the first direction; The coating assembly includes a plurality of coating components, each of which is detachably connected to the connector, and the coating components are arranged at intervals along the first direction.

[0008] In some embodiments, the coated member extends beyond the mounting plate in the thickness direction of the mounting plate, and the end of the coated member extending beyond the mounting plate forms a pressing surface.

[0009] In some embodiments, the coating member is movably connected to the connector, and the coating member is movable relative to the connector in the thickness direction of the mounting plate; wherein, the coating assembly further includes an elastic member, the two ends of which are in contact with the coating member and the connector, respectively; And / or, The pressing surface has a positioning groove that penetrates the coated part along the second direction.

[0010] In some embodiments, at least a portion of the inner wall of the receiving space extends at an angle to the thickness direction of the mounting plate.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] The specific technical features described in the various embodiments in the detailed implementation can be combined in various ways without contradiction. For example, different implementation methods can be formed by combining different specific technical features. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in this invention will not be described separately.

[0019] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0020] Additionally, it should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate any similarity or connection between them. It should be understood that the directional descriptions such as "above," "below," "inside," and "outside" refer to the orientation under normal use conditions.

[0021] Currently, the photovoltaic industry typically coats multiple battery strings one by one in sequence, resulting in low efficiency.

[0022] To solve the above technical problems, refer to Figure 1 In a first aspect, this application provides a coating mechanism, the coating mechanism comprising: Mounting plate 1 has a through groove 11, and the through groove 11 penetrates the mounting plate 1 in the thickness direction of the mounting plate 1; A coating assembly 2 is connected to the mounting plate 1 and extends along a first direction. There are multiple coating assemblies 2, and each coating assembly 2 is spaced apart in a second direction. Both the first direction and the second direction are perpendicular to the thickness direction of the mounting plate 1, and the first direction is perpendicular to the second direction. The coating component 2 surrounds and forms a receiving space that communicates with the through groove 11, and the receiving space has an opening 3. In the thickness direction, the opening 3 is located on the side of the coating component 2 away from the through groove 11.

[0023] The technical solution of this application provides a through groove 11 extending through the thickness direction on the mounting plate 1, and cooperates with multiple sets of coating components 2 extending in the first direction and spaced apart in the second direction. The multiple sets of coating components 2 and the mounting plate 1 together form a receiving space that communicates with the through groove 11 and has an opening 3 facing away from the through groove 11 in the thickness direction. The coating is placed into the receiving space through the through groove 11, and then the coating is simultaneously attached to multiple battery strings arranged in parallel through the opening 3 of the receiving space formed by the multiple sets of spaced coating components 2. This realizes the synchronous coating operation of the battery strings and improves mass production efficiency. At the same time, the multiple sets of coating components 2 share the same mounting plate 1 reference and the uniform medium environment formed by the same through groove 11, which can improve coating consistency and product yield.

[0024] Understandably, the film enters the receiving space through the through groove 11 and is carried and contained by the receiving space during the positioning process of the film coating assembly 2, and at least partially contacts the external environment through the opening 3 of the receiving space. After that, when the film coating assembly 2 completes its positioning and contacts the workpiece to be coated, the film contacts the workpiece to be coated through the opening 3, and then the film is at least partially fixed to the surface of the workpiece to be coated by hot pressing. Then the film coating assembly 2 is displaced, so that the film passes through the receiving space through the opening 3, and the initial coating of the workpiece to be coated is completed.

[0025] In some implementations, refer to Figure 2 The coating component 2 includes: Connector 22 is movably connected to the mounting plate 1 and is capable of moving relative to the mounting plate 1 in the second direction; The film-coated part 23 is connected to the connector 22 and extends out of the connector 22 in the thickness direction of the mounting plate 1, and the film-coated part 23 surrounds and forms the receiving space.

[0026] The technical solution of this embodiment sets the coating assembly 2 to include a connector 22 that can move in the second direction and a coating component 23 connected to the connector 22, so that the coating component 23 can be adjusted in position in the second direction with the connector 22 to adapt to different sizes or positions of the workpiece to be coated.

[0027] It is understood that the connector 22 is a connection structure between the coating assembly 2 and the mounting plate 1, used to enable the coating assembly 2 to move relative to the mounting plate 1 in a second direction. The second direction can be set according to the actual coating requirements, for example, it can be a horizontal direction parallel to the plane of the mounting plate 1, or an inclined direction at a certain angle to the plane of the mounting plate 1. The movable connection method between the connector 22 and the mounting plate 1 can be selected according to the actual design requirements, such as sliding connection, rolling connection, etc. For example, a guide rail extending along the second direction can be set on the mounting plate 1, and a slider cooperating with the guide rail can be set on the connector 22, so that the sliding movement of the connector 22 in the second direction can be realized through the cooperation of the slider and the guide rail; or a groove extending along the second direction can be set on the mounting plate 1, and a roller cooperating with the groove can be set on the connector 22, so that the movement of the connector 22 can be realized through the rolling of the roller in the groove.

[0028] In some implementations, refer to Figure 2 The coating assembly 2 includes two connectors 22, which are arranged at intervals in the second direction; The coating component 23 includes a first coating sub-component 231 and a second coating sub-component 232. The first coating sub-component 231 and the second coating sub-component 232 are respectively connected to the two connecting members 22. The first coating sub-component 231 and the second coating sub-component 232 are arranged at intervals in the second direction, and the first coating sub-component 231 and the second coating sub-component 232 surround to form the receiving space.

[0029] The technical solution of this embodiment provides two connectors 22 arranged at intervals in the second direction within the coating assembly 2, and a first coating sub-component 231 and a second coating sub-component 232 are respectively connected to the two connectors 22, so that the two coating sub-components can move independently in the second direction with their respective connectors 22, thereby adjusting the distance between them and changing the size of the single-row accommodating space in the second direction, so as to accommodate workpieces of different lengths or widths in each single row.

[0030] It can be explained that the structures of the first coating sub-component 231 and the second coating sub-component 232 can be the same or different. When the structures of the first coating sub-component 231 and the second coating sub-component 232 are the same, they can be installed in a mirror-symmetric manner to form an accommodating space. At the same time, the accommodating space can also be formed by the first coating sub-component 231 and the second coating sub-component 232 with different structures.

[0031] In some implementations, refer to Figure 2 The connector 22 extends along the first direction; The coating assembly 2 includes a plurality of coating elements 23, each of which is detachably connected to the connector 22, and the coating elements 23 are arranged at intervals along the first direction.

[0032] The technical solution of this embodiment sets the connector 22 to extend along a first direction, and arranges multiple detachably connected coating elements 23 at intervals along the first direction on the connector 22. This allows the coating assembly 2 to form a multi-segment support and sealing structure in the first direction. By adjusting the number and spacing of the coating elements 23, the size and shape of the accommodating space in the first direction can be changed to adapt to workpieces of different lengths or contours. Simultaneously, the detachable connection design facilitates the replacement and maintenance of individual coating elements 23. When some coating elements 23 are worn or damaged, only the corresponding coating element 23 needs to be replaced, without replacing the entire coating assembly 2, thus reducing maintenance costs. Furthermore, coating elements 23 of different materials or structures can be replaced according to different coating process requirements, improving the versatility of the coating mechanism.

[0033] Understandably, the connector 22 extends along the first direction to form an elongated mounting base, providing continuous mounting positions for multiple coated components 23. The multiple coated components 23 are spaced apart on the connector 22 along the first direction, and each coated component 23 can be independently installed at a different position on the connector 22. By adjusting the spacing between adjacent coated components 23, the effective length of the accommodating space in the first direction or the spacing between two accommodating spaces in the first direction can be changed, thereby adapting to different coating requirements.

[0034] In some implementations, refer to Figure 2 In the thickness direction of the mounting plate 1, the film-coated member 23 extends out of the mounting plate 1, and the end of the film-coated member 23 extending out of the mounting plate 1 forms a pressing surface 4.

[0035] The technical solution of this embodiment sets the coating component 23 to extend out of the mounting plate 1 in the thickness direction and forms a pressing surface 4 at the extended end. During the coating operation, the coating component 23 forms an extension to create a safe gap between the mounting plate 1 surface and the workpiece to be coated, thereby protecting the workpiece. On the other hand, the pressing surface 4 can form a surface contact with the workpiece to be coated or the surface of the coating material, and uniformly transmit pressure to the contact area, thereby improving the contact stability of the coating component 23 with the workpiece to be coated and improving the processing yield.

[0036] In some implementations, refer to Figure 2The coating component 23 is movably connected to the connector 22, and the coating component 23 is movable relative to the connector 22 in the thickness direction of the mounting plate 1; wherein, the coating assembly 2 further includes an elastic component 5, and the two ends of the elastic component 5 are in contact with the coating component 23 and the connector 22 respectively; And / or, The pressing surface 4 has a positioning groove 6, which penetrates the film-coated part 23 along the second direction.

[0037] The technical solution of this embodiment uses a coating component 23 that can move in the thickness direction of the mounting plate 1, along with an elastic component 5. This allows the coating component 23 to adaptively displace during the pressing process via the elastic component 5, compensating for thickness and surface flatness errors in the workpiece to be coated. This ensures uniform contact pressure between the pressing surface 4 and the workpiece surface, thereby increasing the positioning error tolerance of the coating component 23 for the workpiece and protecting the surface of the workpiece during the coating process. The type of elastic component 5 can be selected according to actual needs, such as a compression spring, rubber pad, silicone pad, or disc spring. For example, a cylindrical compression spring can be used, fitted onto a guide post, with one end in contact with the connector 22 and the other end in contact with the coating component 23. When the coating component 23 moves towards the connector 22, the compression spring is compressed, generating a reverse elastic force. Furthermore, this technical solution also improves the accuracy of the coating action by providing a positioning groove 6 penetrating along the second direction on the pressing surface 4 to position the welding strip or other feature structures of the workpiece to be coated, further increasing the product yield. The two technical features can be implemented individually or in combination. When implemented in combination, they can further improve the adaptability of the coating mechanism and the coating quality.

[0038] It is understandable that when both technical features are implemented simultaneously—that is, when the coating part 23 floats due to the elastic element 5 and the pressure surface 4 is provided with a positioning groove 6—a better coating effect can be achieved. During the positioning process, the floating function of the coating part 23 allows the protruding portion of the workpiece to contact the contact surface of the coating part 23 first upon initial contact. During this process, the coating part 23 adaptively avoids the protruding portion through its floating function, thus maintaining uniform pressure on the protruding portion and protecting the structural integrity of the coating part 23 during positioning. Afterward, the coating part 23 displaces to accommodate the protruding portion of the workpiece into the positioning groove 6, forming a locking and engagement, thus achieving the positioning of the workpiece. During this process, the elastic element 5 adaptively deforms to achieve self-locking of the positioning groove 6 of the coating part 23 with the workpiece, improving the accuracy and stability of the positioning.

[0039] In some implementations, refer to Figure 2The extension direction of at least a portion of the inner wall of the accommodating space forms an angle with the thickness direction of the mounting plate 1.

[0040] The technical solution of this embodiment defines an angle between the extension direction of at least a portion of the inner wall of the accommodating space and the thickness direction of the mounting plate 1, thereby forming a cross-sectional structure in the accommodating space that bends and supports the film, thus reducing the lateral dimension of the accommodating space and making the device more compact. Secondly, the thickness direction of the mounting plate 1 is usually also the direction in which the film coating assembly 2 moves away from the workpiece after the initial film coating is completed. In this process, the angled inner wall of the accommodating space bends the planar film into a shape that extends at least partially along the thickness direction of the mounting plate 1, thereby facilitating the process of the film detaching from the accommodating space and improving processing efficiency and yield.

[0041] Specifically, the inner wall of the receiving space includes a bottom surface and side walls. The side walls have an angle relative to the bottom surface, which can be any angle, such as between 30 and 75 degrees. The bottom surface of the receiving space is used to support the coating film. It can be flat or irregularly shaped. The receiving space has an opening 3 on the bottom surface. The coating film contacts the workpiece through the opening 3, so that when the coating film is supported in the receiving space, part of it contacts the bottom surface, while part of it bends and extends along the side walls, thereby reducing the size of the bottom surface and further reducing the lateral size of the receiving space.

[0042] As the coating assembly 2 moves away from the workpiece after completing the initial coating, the thickness direction of the mounting plate 1 becomes the direction of movement of the coating assembly 2. At this time, the angled inner wall within the accommodating space bends the planar coating into a shape that extends at least partially along the thickness direction of the mounting plate 1. This shape reduces the resistance to separation between the coating and the inner wall. Specifically, when the coating material adheres to the inclined sidewall, it forms an inclined curved section with the same angle as the sidewall. When the coating assembly 2 moves upward along the thickness direction of the mounting plate 1, the contact direction between the coating material in the inclined curved section and the sidewall forms an acute angle with the direction of movement. This contact state allows the coating material to gradually slide off along the inclined direction of the sidewall, rather than generating a jamming force perpendicular to the direction of movement like a right-angle structure. This makes the force on the coating material more uniform during the separation process, reducing the possibility of jamming and stretching during the separation process.

[0043] In addition, the inclined sidewalls can also guide the coating material during the coating removal process, allowing the coating material to gradually detach along the inclined direction of the sidewalls, maintaining the flatness and integrity of the coating layer, and improving the processing efficiency of the coating operation and the product qualification rate.

[0044] In some implementations, refer to Figure 2 The inner wall of the accommodating space is a curved surface.

[0045] The technical solution of this embodiment defines the inner wall of the accommodating space as an arc-shaped curved surface to form a continuous transition surface on the inner wall of the accommodating space. More specifically, an arc-shaped transition surface is formed at the corner of the inner wall sidewall portion with an included angle to the bottom portion. This guides the process of the coating assembly 2 moving away from the workpiece along the thickness direction of the mounting plate 1, providing a smooth transition path for the coating material. This guides the coating contained in the accommodating space when the coating assembly 2 detaches from the workpiece, reducing the possibility of the coating getting stuck or being stretched at the corner.

[0046] Specifically, the inner wall of the accommodating space includes a bottom surface and a side wall surface at a certain angle to the bottom surface. An arc-shaped curved surface is set at the corner where the side wall surface and the bottom surface meet. One end of the arc-shaped curved surface is tangent to one side wall surface, and the other end is tangent to the bottom surface. When the coating material is attached to the inner wall of the accommodating space, a curved transition surface matching the arc-shaped curved surface will be formed at the corner. When the coating assembly 2 moves upward away from the workpiece along the thickness direction of the mounting plate 1, the coating material at the opening 3 is fixed to the workpiece by means of hot stamping, etc. The coating material will move relative to the coating assembly 2 along the arc-shaped curved surface, gradually separating from the inner wall of the accommodating space from the bottom surface, and sliding towards the opening 3 along the tangent direction of the arc-shaped curved surface. During this process, the arc-shaped transition surface guides the relative movement trajectory of the coating material, so that the part of the coating that is bent and extended on the side wall surface smoothly transitions from a bent state to a flat state, thereby improving the reliability of the coating movement state during this process.

[0047] Secondly, this application also provides a coating device, referring to Figure 1 and Figure 3 ,include: The coating mechanism as described in any one of the first aspects; The carrier plate 7 is movable relative to the coating assembly 2 in the thickness direction of the mounting plate 1; The carrier plate 7 has a first positioning structure 8, and the mounting plate 1 has a second positioning structure 9. During the movement of the carrier plate 7 in the thickness direction of the mounting plate 1, the first positioning structure 8 and the second positioning structure 9 can come into contact.

[0048] The technical solution of this embodiment provides a first positioning structure 8 on the carrier plate 7 and a second positioning structure 9 on the mounting plate 1, and enables the two to contact each other during the movement of the carrier plate 7 along the thickness direction of the mounting plate 1. This allows the carrier plate 7 to be positioned by contact between the two positioning structures when it moves to a preset position, thereby optimizing the consistency of the coating process and improving the coating quality.

[0049] It can be explained that the coating mechanism refers to the working unit used to complete the coating operation. It includes a mounting plate 1 and a coating assembly 2. The mounting plate 1 provides a mounting base for the coating assembly 2, and the coating assembly 2 is used to cover the surface of the workpiece to be coated with film.

[0050] It can be explained that the carrier plate 7 is a structural component used to support the workpiece to be coated. The workpiece is placed on the carrier plate 7 and moves with the carrier plate 7 to the coating position. After the coating operation is completed, it moves with the carrier plate 7 to the material picking position.

[0051] It can be explained that the relative movement between the mounting plate 1 and the carrier plate 7 can be achieved by the movement of one of them, or by the synchronous relative movement of the two.

[0052] It can be explained that the first positioning structure 8 and the second positioning structure 9 are respectively set on the mounting plate 1 and the carrier plate 7, and can achieve physical contact and positioning connection during the relative displacement of the two in the first direction. For example, it can be the cooperation between a protrusion and a plane, the cooperation between a protrusion and a groove, or the cooperation between a pin and a pin hole, etc.

[0053] In some implementations, refer to Figure 3 and Figure 4 The carrier plate 7 has a transport groove 10; The coating device further includes a transmission mechanism 101, which is capable of moving in the thickness direction of the mounting plate 1 and can move through the transport groove 10 to the space between the carrier plate 7 and the coating mechanism.

[0054] The technical solution of this embodiment provides a transport groove 10 on the carrier plate 7 and a transmission mechanism 101 that can move along the thickness direction of the mounting plate 1 and pass through the transport groove 10. After the workpiece on the carrier plate 7 completes the coating process, the transmission mechanism 101 passes through the transport groove 10 and contacts the coated component 2 on the carrier plate 7, and transports the coated component 2 from the carrier plate 7 to the next station. This allows the component unloading to be completed in place on the carrier plate 7, reducing the travel distance of the carrier plate 7 during component transfer and thus improving the production efficiency of the equipment.

[0055] It can be noted that the transport trough 10 refers to a through-type trough structure formed on the carrier plate 7, which penetrates the carrier plate 7 along the thickness direction of the carrier plate 7. The size, quantity and arrangement of the transport trough 10 must be compatible with the structure of the transmission mechanism 101 to ensure that the transmission mechanism 101 can pass through the transport trough 10 without interference.

[0056] It can be explained that the transfer mechanism 101 refers to a transfer unit used to transport the workpiece to be coated to a designated position on the carrier plate 7, and to output the coated workpiece from the carrier plate 7. The movement direction of the transfer mechanism 101 is limited to the thickness direction of the mounting plate 1, which is consistent with the movement direction of the carrier plate 7. This allows the transfer mechanism 101 to adjust its own height position in a direction perpendicular to the plane of the carrier plate 7, and the transfer direction of the transfer mechanism 101 is away from the carrier plate 7, so as to transfer the coated workpiece to the next station. For example, the transfer mechanism 101 can adopt various transfer forms such as belt type, roller type, chain type, etc.

[0057] It can be explained that the ability of the transmission mechanism 101 to move along the thickness direction of the mounting plate 1 and to pass through the transport groove 10 to reach the space between the carrier plate 7 and the coating mechanism means that the initial position of the transmission mechanism 101 can be located on the side of the carrier plate 7 away from the coating mechanism. When loading and unloading operations are required, the transmission mechanism 101 moves towards the coating mechanism along the thickness direction of the mounting plate 1, passes through the transport groove 10 on the carrier plate 7, and reaches the space between the carrier plate 7 and the coating mechanism. After the workpiece transfer is completed, the transmission mechanism 101 moves in the opposite direction, passes through the transport groove 10 again, and returns to the initial position, so that the loading and unloading operations can be completed without the carrier plate 7 leaving the coating station. In traditional coating devices, the carrier plate 7 needs to move back and forth between the coating station and the loading and unloading station, which increases the ineffective movement stroke, and the overall layout of the equipment needs to reserve space for the movement of the carrier plate 7, resulting in a large equipment footprint. The technical solution in this embodiment completes the loading and unloading by having the transmission mechanism 101 pass through the carrier plate 7, so that the coating station and the loading and unloading station coincide, reducing the movement stroke of the carrier plate 7 and compressing the overall layout space of the equipment.

[0058] It is understood that the transport trough 10 and the transmission mechanism 101 can have various structural forms. For example, the transport trough 10 can be designed as multiple parallel elongated through troughs 11, and the transmission mechanism 101 can be designed as multiple sets of parallel lifting transmission belts; or the transport trough 10 can be designed as a rectangular through trough 11, and the transmission mechanism 101 can be designed as an integral lifting roller assembly.

[0059] In some implementations, refer to Figure 5 and Figure 6 The coating device also includes a welding strip transport assembly 12, which includes a welding strip transport clamp 121. The welding strip transport clamp 121 is capable of displacement along a first direction, and the welding strip transport clamp 121 is collinear with the two positioning grooves 6 of the coating device.

[0060] The technical solution of this embodiment integrates the welding strip installation process into the coating process by adding a welding strip transport clamp 121 that can be displaced along the first direction and making the welding strip transport clamp 121 collinear with the two positioning grooves 6 of the coating device. This allows the two processes to be completed in the same station, eliminating the time for workpiece transfer between the two processes, thereby shortening the connection time between welding strip assembly and coating operations and optimizing the overall work process.

[0061] It should be noted that the welding strip handling clamp 121 refers to a structural component used for clamping and handling welding strips. Its clamping end can be designed to be adapted to the external dimensions of the welding strip, for example, including two rods or two plates that can be close to or far apart from each other.

[0062] It can be explained that the first direction refers to the preset direction of the welding strip transfer, which is also usually the direction of movement of the coating component 2. The welding strip transport clamp 121 can be displaced along the first direction, so that the welding strip is transferred from the material picking position to the positioning groove 6 position, thereby realizing the positioning of the welding strip.

[0063] It can be explained that the solder strip transport clamp 121 is collinear with the two positioning grooves 6 of the coating device. This means that the movement trajectory of the solder strip transport clamp 121 along the first direction coincides with the center line connecting the two positioning grooves 6 on the coating device, or is collinear with the reference line of the two positioning grooves 6. This allows the two ends of the solder strip to be directly aligned with the two positioning grooves 6 when the solder strip transport clamp 121 clamps the solder strip and moves it to the preset position along the first direction, thereby reducing the workload caused by additional adjustments to the solder strip.

[0064] In some implementations, refer to Figure 2 The coating device also includes a hot-pressing part (not shown in the figure), which is movably connected to the coating assembly 2 and can extend out of the receiving space from the opening 3.

[0065] The technical solution of this embodiment connects the hot stamping part to the coating assembly 2 and allows the hot stamping part to pass through the opening 3 of the coating assembly 2 into the receiving space, thereby realizing the integrated operation of local hot stamping and fixing in the coating process. During the coating process, the hot stamping part can be selectively driven to pass through the receiving space according to the operation requirements to perform hot stamping treatment on local positions of the film material and the workpiece to be coated, thereby facilitating the subsequent separation of the coating from the coating assembly 2, reducing the connection time between the hot stamping process and the overall coating process, and thus improving processing efficiency.

[0066] It can be explained that the hot-pressing part refers to the component used to apply high-temperature hot-pressing to a local area of ​​the film material and the workpiece to be coated, so as to achieve local bonding and fixation between the two.

[0067] It can be explained that the hot stamping part is movably connected to the film-coating assembly 2, meaning that the hot stamping part and the film-coating assembly 2 are connected in a way that allows relative movement, enabling the hot stamping part to move in a preset direction and achieve the action of passing through or retracting into the receiving space. The method of movable connection can be selected according to actual design requirements, such as sliding connection, hinge, telescopic connection, etc.

[0068] It can be explained that the ability of the hot stamping part to extend out of the receiving space from the opening 3 means that the hot stamping part, driven by the drive mechanism, can move in a preset direction, which usually points towards the workpiece to be coated, typically the direction of the opening 3 of the receiving space. The hot stamping part can pass through the opening 3 on the coating assembly 2, extending from inside the receiving space to outside the receiving space until it contacts a local area of ​​the film material and the workpiece to be coated, completing the hot stamping operation; after the hot stamping is completed, the hot stamping part can move in the opposite direction, retracting from the opening 3 back into the receiving space, leaving working space for other operations of the coating assembly 2.

[0069] Understandably, the structure, stroke, and heating temperature of the hot-pressing part can be flexibly designed according to the film material and workpiece characteristics. For example, the hot-pressing part can be designed as a telescopic electric heating head, which is driven by a cylinder to achieve telescopic movement, and after passing through the opening 3, it heats the contact point between the film material and the workpiece.

[0070] In some implementations, refer to Figure 7 The coating device also includes a vacuum chamber 13, in which a lifting mechanism 14 is provided. The lifting mechanism 14 can contact the mounting plate 1 and cause the mounting plate 1 to move away from the carrier plate 7 in a first direction.

[0071] The technical solution of this embodiment sets up a vacuum chamber 13 and configures a lifting mechanism 14 that can contact the mounting plate 1 in the vacuum chamber 13 to realize the displacement adjustment of the mounting plate 1 away from the carrier plate 7 in the first direction. In a vacuum negative pressure environment, by lifting the mounting plate 1, the coating gradually adsorbs and adheres to the workpiece, thereby improving the uniformity of coating through the vacuuming capacity of the vacuum chamber 13.

[0072] It can be explained that vacuum chamber 13 refers to a cavity structure used to provide a closed, vacuum-evacuum environment. It adopts a sealed design as a whole, and the internal air can be extracted by vacuum pumps and other equipment to form a preset vacuum degree. The vacuum negative pressure is used to make the film material adhere to the surface of the workpiece, thereby improving the uniformity of film coating.

[0073] It can be explained that the lifting mechanism 14 refers to a structural component installed in the vacuum chamber 13 for driving the mounting plate 1 to move along the first direction. It is installed at the bottom or side wall of the vacuum chamber 13, with its output end facing the mounting plate 1, and can form contact with the surface of the mounting plate 1, thereby driving the mounting plate 1 to move by applying force.

[0074] It can be explained that the first direction refers to the preset displacement direction of the mounting plate 1. Under normal circumstances, this direction is away from the carrier plate 7 and is consistent with the thickness direction of the mounting plate 1.

[0075] It can be explained that the lifting mechanism 14 can contact the mounting plate 1 and cause the mounting plate 1 to move away from the carrier plate 7 in the first direction. This means that during the coating operation, the vacuum chamber 13 first extracts the internal air to form a preset negative pressure environment. Then, under the drive of the driving component, the output end of the lifting mechanism 14 moves toward the mounting plate 1 and contacts the mounting plate 1, causing the mounting plate 1 to move in the first direction, so that the mounting plate 1 moves away from the carrier plate 7. As a result, under the adsorption effect of the vacuum negative pressure, the film material gradually adheres to the surface of the workpiece to be coated on the carrier plate 7 as the mounting plate 1 is lifted until the overall adhesion is completed.

[0076] It is understandable that the specific structural form of the lifting mechanism 14 can be designed according to specific needs. For example, the lifting mechanism 14 can adopt multiple sets of symmetrically arranged lead screws, or adopt a structure of cylinders and guide rods.
