Description

Technical Field

[0001] This utility model relates to a film leveling device. Background Technology

[0002] In the production of photovoltaic modules, each layer of material needs to be leveled before lamination and encapsulation. During the encapsulation process, a polymer layer of encapsulating film is typically formed by covering the surface of the glass cover or composite backsheet. Since precise positioning of the cell array is required after lamination, deformation of the encapsulating film can affect the accuracy of this positioning; therefore, it is crucial to ensure the encapsulating film is as flat as possible. Currently, the leveling method involves using an air knife to blow air across the surface of the encapsulating film after it has been laid to eliminate wrinkles. However, this method only treats the surface of the encapsulating film and fails to address the adhesion between the encapsulating film and the glass cover or composite backsheet, resulting in limitations in the leveling effect. Utility Model Content

[0003] In view of this, the present invention provides a film leveling device, which can level the film covering the workpiece to be processed to the greatest extent, avoid deformation of the film, facilitate subsequent lamination operations, and ensure the normal production of photovoltaic modules.

[0004] To achieve the above objectives, according to one aspect of the present invention, a film leveling device is provided, comprising:

[0005] The system includes a conveying device, a supporting structure, at least one positioning and correction mechanism, and a smoothing module.

[0006] The conveying equipment conveys the parts to be processed, which are covered with a film.

[0007] The support structure is connected to the positioning and correction mechanism and is movably connected to the smoothing module, guiding the smoothing module to move.

[0008] The positioning and correction mechanism corrects the relative position of the adhesive film and the workpiece to be processed, and adsorbs the adhesive film, so that an accommodating space is formed between the adhesive film and the workpiece to be processed;

[0009] Supported and guided by the supporting structure, the smoothing module moves within the receiving space, and the smoothing module provides deionized air to the receiving space to smooth the adhesive film.

[0010] One embodiment of the above-described utility model has the following advantages or beneficial effects: The positioning and correction mechanism performs a positioning and correction operation on the adhesive film on the workpiece to eliminate positional errors between the adhesive film and the workpiece, facilitating subsequent hot-pressing lamination. After positioning and correction, a smoothing module can provide deionized air between the adhesive film and the workpiece to smooth the film, while also removing static electricity and impurities, thus ensuring the flatness of the adhesive film and avoiding the problem of reduced production yield caused by film wrinkles.

[0011] The further effects of the aforementioned unconventional alternative methods will be explained below in conjunction with specific implementation methods. Attached Figure Description

Detailed Implementation

[0021] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of the present invention, including various details to aid understanding. These details should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0022] The photovoltaic modules involved in this embodiment can be any type of photovoltaic module, such as double-glass modules, single-glass modules, etc. The solar cells used in the photovoltaic modules can be any type of solar cell without a main grid (such as silicon-based solar cells, perovskite solar cells, etc., where silicon-based solar cells can be of the cross-type, back-contact type, or type with electrodes on both sides, etc.) cut from.

[0023] Currently, during the production process of photovoltaic modules, static electricity and impurities are often generated when the encapsulant film comes into contact with the glass, which leads to wrinkles in the encapsulant film during subsequent hot-pressing lamination, resulting in substandard quality of the photovoltaic modules.

[0024] In view of the above-mentioned problems, this utility model uses a positioning and correction mechanism 13 installed on the support structure 12 to accurately position and correct the adhesive film covering the surface of the workpiece 15, effectively preventing the subsequent hot-pressing lamination process from being affected by the positional deviation of the adhesive film, thereby ensuring product quality. At the same time, the smoothing module 14, which is movably connected to the support structure 12, can move in the accommodation space between the adhesive film and the workpiece 15, and achieves a dual function by providing deionized air: on the one hand, smoothing the surface of the adhesive film and eliminating wrinkles; on the other hand, removing interface impurities, avoiding problems such as adhesive film deformation or poor adhesion caused by the presence of foreign objects, significantly improving the reliability of the encapsulation process and the product yield.

[0025] Figure 1 The schematic diagram of the adhesive film leveling device according to this utility model is shown below. Figure 1 As shown, the film leveling device includes: a conveying device 11, a supporting structure 12, at least one positioning and correction mechanism 13, and a smoothing module 14, wherein,

[0026] Conveying equipment 11 conveys the parts to be processed 15 covered with adhesive film;

[0027] The support structure 12 is connected to the positioning and correction mechanism 13 and is movably connected to the smoothing module 14, guiding the smoothing module 14 to move.

[0028] The positioning and correction mechanism 13 corrects the relative position of the adhesive film and the workpiece 15 to be treated, and adsorbs the adhesive film, so that a receiving space is formed between the adhesive film and the workpiece 15 to be treated.

[0029] Supported and guided by the support structure 12, the smoothing module 14 moves within the receiving space and provides deionized air to the receiving space to smooth the adhesive film.

[0030] The conveying device 11 transports the workpiece 15 covered with adhesive film to a designated position, whereby the positioning and correction mechanism 13 and the smoothing module 14 perform correction and smoothing operations on the adhesive film and the workpiece 15. The conveying device 11 can transport the workpiece 15 via guide rails, slide rails, or other devices installed on its outer side.

[0031] The component 15 to be processed, covered with an adhesive film, is a glass cover plate in a photovoltaic module. For photovoltaic modules such as double-glass modules, the component 15 to be processed can also be a glass back sheet.

[0032] The support structure 12 is located around the conveying equipment 11 and supports the positioning and correction mechanism 13 and the smoothing module 14. The support structure 12 includes a vertical column and a horizontal beam, which are fixedly connected. The support structure 12 guides the smoothing module 14 to move horizontally within the space between the workpiece 15 and the adhesive film, thus smoothing the adhesive film. The smoothing module 14 is parallel to the surface of the workpiece 15 and perpendicular to its length (or width) or at a certain angle, ensuring that its displacement range covers the workpiece 15. The direction of displacement is not limited; the perpendicular orientation to the length (or width) of the workpiece 15 is merely a preferred embodiment.

[0033] The positioning and correction mechanism 13 is fixedly installed on the support structure 12. It identifies the position of the adhesive film and the workpiece 15 to be processed, determines whether correction is needed, and achieves positioning and correction of the adhesive film by adsorbing the adhesive film and adjusting its position and angle. After the positioning and correction operation is completed, the adsorption of the adhesive film creates a space between the adhesive film and the workpiece 15 to be processed, allowing the subsequent smoothing module 14 to smooth the adhesive film.

[0034] Guided by the support structure 12, the smoothing module 14 shifts within the space between the workpiece 15 and the adhesive film, smoothing the film by blowing deionized air into this space. This process simultaneously eliminates static electricity between the adhesive film and the glass and removes impurities, thereby improving the smoothing effect.

[0035] According to the adhesive film leveling device provided by this utility model, the positioning and correction mechanism 13 can perform positioning and correction operations on the adhesive film on the workpiece 15 to correct the positional error of the adhesive film relative to the workpiece 15, facilitating subsequent hot-pressing lamination. After the positioning and correction operation, the smoothing module 14 can provide deionized air blowing between the adhesive film and the workpiece 15 to smooth the adhesive film, while also removing static electricity and impurities, ensuring the flatness of the adhesive film and avoiding the problem of reduced productivity caused by adhesive film wrinkles.

[0036] In one embodiment, the support structure 12 includes two first linear modules 121; the two first linear modules 121 are distributed on opposite sides of the conveying device 11; the two first linear modules 121 are respectively connected to the smoothing module 14 and the positioning and correction mechanism 13, and the two first linear modules 121 are used to guide the smoothing module 14 to move along the extension direction of the first linear module 121.

[0037] A first linear module 121 is installed on each of the opposite sides of the support structure 12. Each first linear module 121 is connected to a smoothing module 14 and a positioning and correction mechanism 13. The smoothing module 14 is guided to move along the extension direction of the first linear module 121 by the coupled motion between the two first linear modules 121. The first linear modules 121 can be installed on the crossbeams of the support structure 12.

[0038] In one embodiment, there is one positioning and correction mechanism 13, which is movably connected to two first linear modules 121; the two first linear modules 121 guide the positioning and correction mechanism 13 to shift in the width or length direction of the edge of the workpiece 15; or, there are at least two positioning and correction mechanisms 13; at least two positioning and correction mechanisms 13 are fixedly connected to two first linear modules 121.

[0039] like Figure 1 As shown, the adhesive film leveling device may include a movable positioning and correction mechanism 13, which can perform omnidirectional positioning and correction operations on the adhesive film through movement. The positioning and correction mechanism 13 is movably connected to the support structure 12 to ensure that the positioning and correction mechanism 13 can be moved. Specifically, the support structure 12 includes two first linear modules 121, used to guide the positioning and correction mechanism 13 and the smoothing module 14 to move along the direction of the first linear modules 121. After completing the positioning and correction operation at one end of the workpiece 15, the positioning and correction mechanism 13 moves along the direction of the first linear modules 121, i.e., the width or length direction of the workpiece 15, to the other end of the workpiece 15 to perform the positioning and correction operation.

[0040] Two first linear modules 121 are positioned on opposite and parallel sides of the conveying device 11, that is, on opposite sides of the conveying device 11 in either the length or width direction, or on opposite sides of the support structure 12. Since the support structure 12 is arranged around the outside of the conveying device 11, their length and width directions are corresponding for ease of operation. Each first linear module 121 includes two guide rails, which are used to guide the positioning and correction mechanism 13 and the smoothing module 14 to shift, respectively. The two guide rails in the two opposing first linear modules 121 correspond one-to-one. The two first linear modules 121 guide the positioning and correction mechanism 13 and the smoothing module 14 to shift along the direction of the first linear module 121 through mutual coupling.

[0041] According to the adhesive film leveling device provided by this utility model, the positioning and correction mechanism 13 and the smoothing module 14 can be moved by the first straight module 121 to complete the correction and smoothing of the entire adhesive film, which greatly improves the smoothing effect of the adhesive film and provides a guarantee for subsequent hot pressing and lamination.

[0042] Figure 2 This is a schematic diagram of another structure of the adhesive film leveling device according to this utility model, as shown below. Figure 2 As shown, the positioning and correction mechanism in the adhesive film leveling device can also be two fixed-position positioning and correction mechanisms 13, respectively set at both ends of the workpiece 15 to be processed. These mechanisms correct the position of the adhesive film by adsorbing the four corners of the adhesive film covering the workpiece 15. The fixed-position positioning and correction mechanism 13 is fixedly connected to the support structure 12. When the positioning and correction mechanism 13 is fixedly set, the first linear module 121 on the support structure 12 contains only one guide rail, used to guide the leveling module 14 to move along the direction of the guide rail, i.e., the width or length direction of the workpiece 15 to complete the overall leveling operation of the adhesive film. The fixed-position positioning and correction mechanism 13 can directly complete the positioning and correction operation of both ends of the adhesive film on the workpiece 15 in one operation, without the need for further displacement.

[0043] In one embodiment, the support structure 12 includes a main frame 122 and at least two clamping portions 123 distributed on the main frame 122; the clamping portions 123 are fixedly connected to the main frame 122; the clamping portions 123 are used to clamp the adhesive film and the edge of the workpiece 15 to be processed.

[0044] like Figure 1As shown, the support structure 12 mainly comprises two parts: a main frame 122 and clamping parts 123 on the main frame 122. The main frame 122 includes four columns surrounding the conveying device 11 and two crossbeams on opposite sides of the columns. At least two clamping parts 123 are fixedly connected to the columns of the main frame 122 for clamping and fixing the edge position of the workpiece 15 to be processed on the conveying device 11. Preferably, there are two or four clamping parts 123. When there are two clamping parts 123, they can be respectively set on two columns on opposite sides, and the two clamping parts 123 are located at the same end on the two columns. By clamping the edges of the workpiece 15 or the adhesive film and the opposite sides of the workpiece 15, the workpiece 15 or the adhesive film and one end of the workpiece 15 are fixed. When there are four clamping parts 123, they can be respectively set on four columns, and by clamping the corner edges of the workpiece 15 or the adhesive film and the corners of the workpiece 15, the four corners of the workpiece 15 or the adhesive film and the workpiece 15 are fixed.

[0045] The structure of the main frame 122 is not limited to a structure of four columns and two beams. It can also include other structures that can achieve the same support. For example, replacing the four columns with two opposing uprights can also achieve the technical effect of this utility model.

[0046] In one embodiment, the clamping part 123 includes a telescopic cylinder 1221 and a fixed gripper 1222. The telescopic cylinder 1221 is mounted on the main frame 122; the fixed gripper 1222 is mounted on the side of the telescopic cylinder 1221 facing the conveying device 11.

[0047] like Figure 3 As shown, the clamping part 123 may specifically include a telescopic cylinder 1221 for adjusting the clamping position and a fixed gripper 1222 for clamping the workpiece 15 or the film to be processed and the workpiece 15. The telescopic cylinder 1221 is fixed to the main frame 121, specifically to the column of the main frame 122, and is positioned from the column towards the conveying device 11. The fixed gripper 1222 is located at one end of the telescopic cylinder 1221, specifically on the side facing the conveying device 11. When the piston rod of the telescopic cylinder 1221 extends, the fixed gripper 1222 extends to the edge of the workpiece 15 on the conveying device 11 to fix the workpiece 15; when the piston rod of the telescopic cylinder 1221 retracts, the fixed gripper 1222 retracts, releasing the fixation of the workpiece 15. The fixing of the part to be treated 15 is carried out when the smoothing module 14 is moved to a certain distance from the positioning and correction mechanism 13 during the purging process, in order to avoid the film displacement caused by purging.

[0048] According to the adhesive film leveling device provided by this utility model, in the smoothing stage after the positioning and correction operation is completed, when the smoothing module 14 has shifted a certain distance, the device can fix the adhesive film and the smoothed end of the workpiece 15. This fixing effect can effectively avoid the error caused by the displacement of the adhesive film due to the smoothing module 14 during the blowing process, thereby ensuring that the subsequent hot pressing and laminating operation can be carried out smoothly.

[0049] In one embodiment, the positioning and correction mechanism 13 includes a correction support mechanism 131, two correction cameras 132, and two correction modules 133. The two ends of the correction support mechanism 131 are movably connected to two first linear modules 121, and under the action of a driving force, they shift along the extending direction of the first linear modules 121. The two correction cameras 132 and the two correction modules 133 are respectively mounted on the correction support mechanism 131, and the two correction modules 133 are located below the two correction cameras 132. The correction cameras 132 are used to take pictures of the corner area of ​​the workpiece 15 to be processed, and to identify the offset position between the adhesive film and the workpiece 15 based on the captured image. The correction modules 133 correct the position of the adhesive film by adsorption based on the identified offset position between the adhesive film and the workpiece 15. The correction cameras 132 can be CCD cameras or other camera types capable of image recognition.

[0050] like Figure 4 As shown, the positioning and correction mechanism 13 may include a correction support mechanism 131, a correction camera 132, and a correction module 133. The correction support mechanism 131 is fixedly mounted with the correction camera 132 and the correction module 133, which work together to correct the position of the adhesive film covering the workpiece 15. Figure 4In the frame structure shown, both the correction camera 132 and the correction module 133 are fixed on the correction support mechanism 131. The correction support mechanism 131 is movably connected at both ends to two first linear modules 121. Through the coupled operation of the two first linear modules 121, the correction support mechanism 131 is moved along the extension direction of the first linear modules 121, thereby achieving multi-position correction of the adhesive film covering the workpiece 15. The two correction cameras 132 and the two correction modules 133 are respectively installed on both sides of the correction support mechanism 131, with the correction module 133 installed below the correction camera 132. The correction camera 132 is used to capture the edge position of the workpiece 15 below the camera, specifically the corner area of ​​the workpiece 15, and controls the correction module 133 to perform correction based on the positional error between the adhesive film covering the workpiece 15 and the workpiece 15. Specifically, the correction camera 132 identifies the positional offset between the adhesive film and the workpiece 15 by taking a photo of the corner area of ​​the workpiece 15 to be processed, and controls the correction module 133 to adjust the position of the adhesive film by adsorption, and finally completes the correction operation.

[0051] According to the adhesive film leveling device provided by this utility model, the adhesive film and the workpiece 15 to be processed can be photographed by a set camera to identify the positional error between the two, and the position of the adhesive film can be adjusted according to the identified positional error, which greatly reduces the probability of photovoltaic module quality failure due to adhesive film positional deviation.

[0052] In one embodiment, the correction module 133 includes a moving module 1331, a correction motor 1332, and a correction suction cup 1333; the moving module 1331 is connected to the correction motor 1332, and the moving module 1331 causes the correction motor 1332 to shift in the horizontal and / or vertical directions through mechanical structural changes; the correction suction cup 1333 is fixedly installed below the correction motor 1332, and adjusts the position of the corresponding adhesive film under the drive of the correction motor 1332.

[0053] The correction module 133 includes a moving module 1331 for guiding the correction motor 1332 to move, thereby achieving correction operations on different positions of the adhesive film. The correction motor 1332 drives the lower correction suction cup 1333 to adsorb the adhesive film, and adjusts the position of the adhesive film through operations such as rotation angle and displacement.

[0054] In one embodiment, the moving module 1331 includes a second linear module 13311 arranged horizontally and a third linear module 13312 arranged vertically; the second linear module 13311 is fixed on the correction support mechanism 131; the second linear module 13311 and the third linear module 13312 are movably connected; the correction motor 1332 is movably connected to the third linear module 13312; the third linear module 13312 moves horizontally along the second linear module 13311, driving the correction motor 1332 to move horizontally, and the third linear module 13312 controls the correction motor 1332 to move vertically; wherein, the second linear module 13311 and the third linear module 13312 are perpendicular to each other.

[0055] like Figure 5 As shown, each correction module 133 includes a moving module 1331, a correction motor 1332, and a correction suction cup 1333. The moving module 1331 includes a second linear module 13311 and a third linear module 13312 that are perpendicular to each other. These two linear modules in different directions can guide the correction motor 1332 and the correction suction cup 1333 to move in two directions to correct the adhesive film. Specifically, the second linear module 13311 is a horizontal linear module, fixed on the correction support mechanism 131, used to guide the correction motor 1332 and the correction suction cup 1333 to move horizontally; the third linear module 13312 is a vertical linear module, movably connected to the second linear module 13311 and also movably connected to the correction motor 1332, with the correction suction cup 1333 fixed below the correction motor 1332. Guided by the third linear module 13312, the correction motor 1332 and the correction suction cup 1333 move vertically. Driven by the correction motor 1332, the correction suction cup 1333 completes the position correction of the adhesive film by adsorbing the film and performing rotation and displacement actions.

[0056] In addition to the above embodiments, the moving module 1331 may also include a fourth linear module in the vertical direction and a fifth linear module in the horizontal direction. The fourth linear module is fixedly connected to the correction support mechanism 131 and is used to guide the correction motor 1332 and the correction suction cup 1333 to move in the vertical direction; the fifth linear module is movably connected to the fourth linear module and is used to guide the correction motor 1332 and the correction suction cup 1333 to move in the horizontal direction.

[0057] In one embodiment, the correction module 133 further includes a first smoothing air knife 1334; the first smoothing air knife 1334 is installed on the side of the correction suction cup 1333 away from the conveying device 11, and is used to smooth the corner area of ​​the adhesive film.

[0058] To further smooth the adhesive film, a smoothing air knife can be added to the web guiding module 133. For example... Figure 5As shown, the first smoothing air knife 1334 is installed on one side of the alignment suction cup 1333, specifically on the side away from the conveying device 11. After the positioning and alignment operation of the adhesive film is completed, as the moving module 1331 guides the alignment suction cup 1333 to move horizontally away from the conveying device 11, the first smoothing air knife 1334 moves in the same direction and blows and smooths the corner areas of the adhesive film. Similarly, the four corner areas of the adhesive film are blown and smoothed.

[0059] According to the adhesive film leveling device provided by this utility model, the corner area of ​​the adhesive film can be swept and leveled by the first smoothing air knife 1334 installed on the correction suction cup 1333, which further improves the smoothing effect of the adhesive film and improves the yield of subsequent hot pressing and laminating processes.

[0060] In one embodiment, the smoothing module 14 includes a connecting mechanism 141 and a second smoothing air knife 142; the two connecting mechanisms 141 are respectively movably connected to two first linear modules 121 and move along the extension direction of the first linear modules 121; the two ends of the second smoothing air knife 142 are respectively mounted on the two connecting mechanisms 141.

[0061] like Figure 6 As shown, in addition to the first smoothing air knife 1334 for smoothing the corner areas of the adhesive film, the adhesive film leveling device may also include a second smoothing air knife 142 for smoothing the entire area of ​​the adhesive film. Figure 6 As shown, the smoothing module 14 includes a connecting mechanism 141 and a second smoothing air knife 142, used to smooth the entire adhesive film. Specifically, two connecting mechanisms 141 are installed at both ends of the second smoothing air knife 142, for movably connecting to the first linear module 121 respectively. When the connecting mechanism 141 and the positioning and correction mechanism 13 are connected to the first linear module 121, they are respectively connected to the two guide rails of the first linear module 121. After the positioning and correction operation is completed, the connecting mechanism 141 moves along the extension direction of the first linear module 121, and drives the second smoothing air knife 142 to move.

[0062] In one embodiment, the conveying device 11 includes a transport support mechanism 111 and a transport guide rail 112. The transport support mechanism 111 is installed between two support structures 12 for supporting the workpiece 15 covered with adhesive film. The transport guide rail 112 is installed above the transport support mechanism 111 for transporting the workpiece 15 covered with adhesive film. To facilitate the operation of the workpiece 15, the transport guide rail 112 is installed above the transport support mechanism 111, and the transport support mechanism 111 is installed between the two support structures 12, so that the positioning and correction mechanism 13 and the smoothing module 14 can operate above the transport support mechanism 111.

[0063] In one embodiment, the conveying device 11 further includes a proximity switch and a limit cylinder mounted on the transport guide rail 112, the proximity switch and the limit cylinder being used to position the workpiece 15 on the transport guide rail 112.

[0064] The conveying equipment 11 further includes a proximity switch and a limit cylinder, both mounted on the transport guide rail 112. These are used to position the workpiece 15 to be processed on the transport guide rail 112, ensuring it stops within the operating range of the positioning and correction mechanism 13 and the smoothing module 14. Specifically, when the workpiece 15 is transported to the proximity switch, the transport guide rail 112 is stopped, and the position of the workpiece 15 is adjusted by the limit cylinder, ensuring that all transported workpieces 15 stop at the same position for processing.

[0065] According to the adhesive film leveling device provided by this utility model, the proximity switch and limit cylinder installed on the transport guide rail 112 of the conveying equipment 11 can complete the initial positioning of the workpiece 15 to be processed, so that all transported workpieces 15 to be processed can stay in the same position for positioning correction and adhesive film leveling operations.

[0066] In one embodiment, the second smoothing air knife 142 is a deionized smoothing air knife, and the blowing port of the second smoothing air knife 142 is oriented in the direction of movement of the second smoothing air knife 142.

[0067] The second smoothing air knife 142 is a deionized air knife, capable of providing deionized air to blow between the adhesive film and the workpiece 15, removing static electricity and impurities between the adhesive film and the workpiece 15, and also smoothing the adhesive film to prevent wrinkles. The blowing direction of the second smoothing air knife 142 is the same as the moving direction of the second smoothing air knife 142 during blowing.

[0068] In one embodiment, the length of the second smoothing air knife 142 is longer than the width of the adhesive film and the air vents of the second smoothing air knife 142 are evenly distributed. The second smoothing air knife 142 extends along a first direction in which the width or length of the conveying device 11 is located, and moves along a second direction perpendicular to the first direction to blow away the workpiece 15 covered with the adhesive film.

[0069] To ensure that the second smoothing air knife 142 can effectively clean the adhesive film and all parts of the workpiece 15, the length of the second smoothing air knife 142 is longer than the width of the adhesive film, and the second smoothing air knife 142 extends along a first direction containing the width or length of the conveying device 11. When the second smoothing air knife 142 moves in a second direction perpendicular to the first direction, it can move from one side of the adhesive film to the other side between the adhesive film and the workpiece 15, cleaning the entire adhesive film and workpiece 15. Simultaneously, to ensure the cleaning effect, the air ports on the second smoothing air knife 142 are evenly distributed, maximizing the cleaning effect.

[0070] According to the adhesive film leveling device provided by this utility model, the positioning and correction mechanism 13 can take pictures of the position of the adhesive film covering the workpiece 15 and identify the position error, so as to correct the position of the adhesive film based on the position error and avoid the position error affecting the subsequent hot pressing and laminating process; the second smoothing air knife 142 can also blow between the adhesive film and the workpiece 15, which can smooth the adhesive film and remove the charge and impurities on the surface of both, so as to avoid the unevenness of the adhesive film caused by static electricity or impurities, which would affect the subsequent hot pressing and laminating operation, and greatly improve the product qualification rate in the subsequent production process.

[0071] The adhesive film leveling process of this utility model is as follows: After the conveying device 11 conveys the workpiece 15 covered with adhesive film to the preset position via the transport guide rail 112, a proximity switch is triggered, the transport guide rail 112 stops, the limit cylinder rises and limits the workpiece 15, and after completion, the limit cylinder descends. The positioning and correction mechanism 13 moves along the first linear module 121 to the initial photographing position (the initial position of the positioning and correction mechanism 13 can be set as the initial photographing position), the correction camera 132 takes a picture of the workpiece 15 and identifies the relative position of the adhesive film and the workpiece 15. According to the identification result, the guide correction module 133 moves along the second linear module 13311 and the third linear module 13312, and the adhesive film is adsorbed by the correction suction cup 1333 to perform the positioning and correction of the adhesive film. After positioning and correction are completed, the correction suction cup 1333 is kept at the correction position. The second smoothing air knife 142 is moved to the first linear module 121 via two connecting mechanisms 141, wherein the correction position is higher than the position of the second smoothing air knife 142. The second smoothing air knife 142 blows between the adhesive film and the workpiece 15. After the second smoothing air knife 142 moves a certain distance away from the initial position, the correction suction cup 1333 descends to release the adhesive film. At the same time, the device fixes one end of the blowing of the adhesive film and the workpiece 15 through the clamping part 123 to prevent the adhesive film from shifting during the blowing process. After fixing, the correction suction cup 1333 rises to the safety position (the safety position is not lower than the height of the correction position). After the blowing is completed, the positioning and correction mechanism 13 moves to the termination imaging position for secondary detection. If there is an error between the adhesive film and the workpiece 15, the correction motor 1332 is used again to drive the positioning and correction operation.
