[0032] The technical solution provided by the embodiments of the present application is described below in conjunction with the accompanying drawings.

[0033] See also Figure 1-Figure 3As shown, the present application provides a coating device 100, which includes a machine 110, a multi-axis module 120 and an adsorbent 130. The machine 110 has a bearing position (not shown in the figure) and a material taking position (not shown in the figure). The bearing position is used to carry the part to be coated (not shown in the figure), and the material taking position is used to carry a film (not shown in the figure). The multi-axis module 120 is movably arranged on the machine 110. The coating device 100 is used to attach a film to the surface of the part to be coated. For example, the multi-axis module 120 can reciprocate between the bearing position and the material taking position to take the film carried by the material taking position to the bearing position for coating the part to be coated. Among them, the part to be coated can be an LCM (LCD Module, LCD display module or liquid crystal module), a printed circuit board and other components. The present application does not limit the specific component type of the part to be coated. Preferably, the carrying position is a contoured cavity provided on the machine 110 to accommodate the carrying of the piece to be coated, and the material discharge position is also a contoured cavity provided on the machine 110 to accommodate the carrying of the film to be attached.

[0034] The adsorbent 130 is pivotally connected to the multi-axis module 120, that is, the adsorbent 130 is disposed on the multi-axis module 120, and the adsorbent 130 can rotate relative to the multi-axis module 120. The adsorbent 130 is used to adsorb the film. For example, in the process of coating the part to be coated, the adsorbent 130 can adsorb the film to the bearing position at the material taking position, and the adsorbent 130 can release the adsorption effect on the film to attach the film to the attachment surface of the part to be coated. The adsorbent 130 has a first end 131 and a second end 132 opposite to each other. The adsorbent 130 has an inclined surface 133 at a position close to the first end 131. The inclined surface 133 faces the bearing position, and the inclined surface 133 can cooperate with the attachment surface of the part to be coated.

[0035] The above-mentioned coating device 100, when it is necessary to coat the workpiece to be coated, first, the multi-axis module 120 drives the adsorption component 130 to move to the material taking position to adsorb the film and take the material; then, after the adsorption component 130 adsorbs the film, the multi-axis module 120 drives the adsorption component 130 to move toward a position close to the workpiece to be coated; then, the adsorption component 130 rotates relative to the multi-axis module 120, so that the inclined surface 133 is pre-attached to the attachment surface of the workpiece to be coated; finally, the multi-axis module 120 drives the adsorption component 130 to move from the first end 131 to the second end 132, and during the movement of the multi-axis module 120 from the first end 131 to the second end 132, the adsorption component 130 releases the adsorption effect on the film, and the attachment operation of the film on the workpiece to be coated is performed from the first end 131 to the second end 132. In the coating device 100 provided in the present application, during the lamination process of the film on the workpiece to be coated, the adsorption member 130 is in an inclined state, that is, the adsorption member 130 is in an inclined state with the first end 131 being low and the second end 132 being high. The bubbles generated between the film and the attachment surface of the workpiece to be coated are discharged from the first end 131 toward the second end 132, thereby reducing the bubbles generated in the workpiece to be coated during the lamination process and improving the lamination quality of the workpiece to be coated.

[0036] When the multi-axis module 120 drives the adsorption member 130 to move from the first end 131 to the second end 132 , the film can be smoothed manually or with auxiliary tools to discharge bubbles generated between the film and the surface of the film to be coated.

[0037] In order to discharge the bubbles generated between the film and the surface of the film-coated member, in one embodiment, refer to Figure 1-Figure 3 As shown, the coating device 100 also includes a rolling module 140. The rolling module 140 is arranged on the multi-axis module 120. In the process of attaching the film to the piece to be coated, the rolling module 140 can roll on the surface of the film away from the attachment surface of the piece to be coated. In this way, when the multi-axis module 120 moves from the first end 131 to the second end 132, the multi-axis module 120 can drive the rolling module 140 to move from the first end 131 to the second end 132. The rolling module 140 applies pressure to the surface of the film to discharge bubbles generated between the film and the attachment surface of the piece to be coated, and improve the attachment flatness of the film on the piece to be coated, thereby improving the coating quality of the film.

[0038] Specifically, see Figure 1-Figure 3As shown, the rolling module 140 includes a first driving member 141 and a roller 142. The first driving member 141 is disposed on the multi-axis module 120 through a bracket, and the first driving member 141 is in transmission connection with the roller 142. For example, the roller 142 is disposed at the output end of the first driving member 141, and the first driving member 141 is used to adjust the position of the roller 142 so that the roller 142 can roll on the surface of the film. As in the present embodiment, when the multi-axis module 120 drives the adsorption component 130 and the roller 142 module to move to a position close to the piece to be coated, the first driving component 141 outputs power to the roller 142 so that the roller 142 is pressed against the surface of the film, and when the multi-axis module 120 drives the adsorption component 130 and the roller 142 module to move along the direction from the first end 131 to the second end 132, the roller 142 moves along the direction from the first end 131 to the second end 132 on the surface of the film so as to discharge the bubbles generated between the film and the attachment surface of the piece to be coated from the first end 131 toward the second end 132, thereby reducing the bubbles generated during the coating process of the piece to be coated and improving the coating quality of the piece to be coated.

[0039] The first driving member 141 may be a driving motor, a driving cylinder or other element capable of outputting power. The present application does not impose any limitation on the specific element type of the first driving member 141 .

[0040] In one embodiment, refer to Figure 1-Figure 3 As shown, the coating device 100 further includes a second driving member 150. The second driving member 150 is disposed on the multi-axis module 120 through a bracket, and the second driving member 150 is close to the first end 131. The second driving member 150 can apply a force to the first end 131 to make the inclined surface 133 fit the attachment surface of the coating member. As in the present embodiment, when the multi-axis module 120 drives the adsorption member 130 and the second driving member 150 to move to a position close to the piece to be coated, the second driving member 150 outputs power and abuts against the first end 131. Since the adsorption member 130 is pivotally connected to the multi-axis module 120, the adsorption member 130 rotates relative to the multi-axis module 120, the first end 131 moves toward the direction close to the piece to be coated, and the second end 132 moves toward the direction away from the piece to be coated. The adsorption member 130 presents a state in which the first end 131 is low and the second end 132 is high. The film adsorbed by the first end 131 is first attached to the piece to be coated, and the film adsorbed by the second end 132 is later attached to the piece to be coated, that is, the attachment operation of the film on the piece to be coated is performed from the first end 131 to the second end 132, and the bubbles generated between the film and the attachment surface of the piece to be coated are discharged from the first end 131 to the second end 132, thereby reducing the bubbles generated by the piece to be coated during the coating process and improving the coating quality of the piece to be coated.

[0041] Further, see Figure 3As shown, the adsorption member 130 has a connection portion 134, and the first end 131 and the second end 132 are respectively located at the two ends of the connection portion 134. The connection portion 134 is rotatably connected to the multi-axis module 120 through the pin shaft 135, and the second driving member 150 outputs power and abuts against the first end 131. The connection portion 134 rotates relative to the pin shaft 135, and the first end 131 moves toward the direction close to the object to be coated, and the second end 132 moves toward the direction away from the object to be coated. The film adsorbed by the first end 131 is first attached to the object to be coated, and the film adsorbed by the second end 132 is then attached to the object to be coated, that is, the film attaching operation on the object to be coated is performed from the first end 131 to the second end 132.

[0042] The second driving member 150 may be a driving motor, a driving cylinder or other element capable of outputting power. The present application does not impose any limitation on the specific element type of the second driving member 150 .

[0043] In order to complete the film lamination operation on the film-coated part, in one embodiment, refer to Figure 1-Figure 3 As shown, the multi-axis module 120 includes an X-axis module 121, a Y-axis module 122, a Z-axis module 123 and a rotation module 124. The X-axis module 121, the Y-axis module 122, the Z-axis module 123 and the rotation module 124 are all connected to the adsorption member 130 in a transmission manner. The X-axis module 121 and the Y-axis module 122 are used to adjust the position of the adsorption member 130 in the horizontal direction, and the Z-axis module 123 is used to adjust the position of the adsorption member 130 in the vertical direction, that is, the X-axis module 121, the Y-axis module 122 and the Z-axis module 123 can drive the adsorption member 130 to move in a three-dimensional space, so that the adsorption member 130 can move toward a position close to the part to be coated, and when the film needs to be attached to the part to be coated, the multi-axis module 120 drives the adsorption member 130 to move in the direction from the first end 131 to the second end 132, so that the film is attached to the part to be coated from the first end 131 to the second end 132, and the film coating operation of the film on the part to be coated is completed. Furthermore, the rotating module 124 is used to adjust the angle of the adsorption member 130 so that the film is attached to the object to be coated according to a preset direction and angle.

[0044] Specifically, for example, the X-axis module 121 is arranged on the machine platform 110 by welding, screwing, etc., and the Y-axis module 122 is arranged along the Figure 1 The X-axis module 121 is arranged to slide along the X direction, and the Z-axis module 123 is arranged to slide along the X direction. Figure 1 The Y-axis module 122 is slidably arranged in the Y direction, and the Y-axis module 122 indirectly arranges the Z-axis module 123 on the X-axis module 121, and the rotation module 124 is arranged along the Figure 1 The Z-axis module 123 is slideably disposed in the Z-axis direction, and the Z-axis module 123 indirectly disposes the rotation module 124 on the X-axis module 121 and the Y-axis module 122. Figure 1The rotation in the θ direction is set in the rotating module 124. For example, during the laminating operation of the film on the piece to be coated, the X-axis module 121, the Y-axis module 122 and the Z-axis module 123 are used to adjust the position of the adsorbent 130 in the X, Y and Z directions, and drive the adsorbent 130 to move in three-dimensional space, so that the adsorbent 130 can move toward a position close to the piece to be coated, and after the inclined surface 133 is attached to the attachment surface of the piece to be coated, the multi-axis module 120 drives the adsorbent 130 to move from the first end 131 to the second end 132, so that the film is attached to the piece to be coated from the first end 131 to the second end 132.

[0045] Among them, in this embodiment, the X-axis module 121, the Y-axis module 122 and the Z-axis module 123 can be a slide rail and slider module, a screw module or a gear rack, etc. The application does not limit the specific component types of the X-axis module 121, the Y-axis module 122 and the Z-axis module 123. In addition, the rotation module 124 can be a turntable module, a turntable module, etc. The application does not limit the specific component types of the rotation module 124.

[0046] In one embodiment, refer to Figure 2 and Figure 3 As shown, the adsorption member 130 is a plate structure, and the adsorption member 130 is provided with a plurality of adsorption holes (not shown) on the side facing the bearing position. Through the negative pressure adsorption effect of the adsorption holes, the adsorption operation of the adsorption member 130 on the film can be realized. Preferably, the plurality of adsorption holes are evenly arranged on the adsorption member 130 to improve the adsorption reliability and adsorption flatness of the adsorption member 130 on the film.

[0047] Further, see Figure 2 and Figure 3 As shown, the film coating device 100 further includes a ventilation module (not shown in the figure), which is used to introduce gas into the adsorption hole. Exemplarily, when the adsorbent 130 needs to move to the material taking position to perform the adsorption and material taking operation of the film, the ventilation module introduces negative pressure gas into the adsorption hole, and the adsorption operation of the film by the adsorbent 130 is realized through the negative pressure adsorption effect of the adsorption hole; and when the adsorbent 130 needs to attach the film to the part to be coated, the ventilation module introduces positive pressure gas into the adsorption hole to release the adsorption effect of the adsorbent 130 on the film, so as to realize the attachment operation of the film to the part to be coated.

[0048] In one embodiment, refer to Figure 1 and Figure 2As shown, the film coating device 100 further includes a camera module 160. The camera module 160 is arranged on the multi-axis module 120 through a bracket, and the camera module 160 is used to obtain the position information of the film at the material taking position. Since the film is generally conveyed to the material taking position by means of a conveyor belt, a conveyor chain, etc., the position of the film at the material taking position may be offset. By obtaining the position information of the film at the material taking position by the camera module 160, the position of the film can be located. When the position of the film at the material taking position is offset, the position of the film can be adjusted in time to ensure the position accuracy of the film adsorbed by the adsorbent 130.

[0049] Also, see Figure 1-Figure 3 As shown, the present application further provides a detection line (not shown in the figure). The detection line includes a coating device 100 as described above, and the detection line is used to attach a film to the surface of a piece to be coated.

[0050] In the above-mentioned coating device 100, during the bonding process of the film to the workpiece to be coated, the adsorption member 130 is in an inclined state, that is, the adsorption member 130 is in an inclined state with the first end 131 being low and the second end 132 being high. The bubbles generated between the film and the bonding surface of the workpiece to be coated are discharged from the first end 131 toward the second end 132, thereby reducing the bubbles generated in the workpiece to be coated during the coating process and improving the coating quality of the workpiece to be coated.

[0051] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
