[0032] All terms used in this application have the same meaning as those understood by those of ordinary skill in the art to which this application belongs, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries, such as general dictionaries, should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined herein.

[0033] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0034] like Figures 1 to 6As shown, the exposure, development and spraying jig disclosed in the embodiment of the present application includes a first jig component 10 and a second jig component 20, the first jig component 10 includes a first profiling surface 11 and a hollow structure 12, the first profiling surface 11 is consistent with the shape of the first side surface of the glass to be sprayed, the hollow structure 12 is arranged on the first profiling surface 11, the hollow structure 12 is arranged corresponding to the area to be sprayed, and the area to be sprayed is located on the first side surface of the glass to be sprayed, the second jig component 20 is rotatably connected to the first jig component 10, the second jig component 20 has a second profiling surface 21, and the second profiling surface 21 is consistent with the shape of the second side surface of the glass to be sprayed, and the first jig component 10 has a spraying state close to the second jig component 20 and a state to be sprayed away from the second jig component 20.

[0035] By applying the technical solution of the embodiment of the present application, the glass to be sprayed is placed on the second fixture assembly 20, the second side surface of the glass is fitted with the second profiling surface 21, the first fixture assembly 10 is rotated to fit the first profiling surface 11 with the first side surface of the glass, at this time, the hollow structure 12 is set corresponding to the area of ​​the glass to be sprayed, and the glass is sprayed with ink, and the ink passes through the hollow structure 12 and contacts the glass, and will not splash to the non-spraying area on the glass. The technical solution of the embodiment of the present application effectively solves the problem of poor product quality caused by ink splashing to the non-spraying area during the exposure, development and spraying process in the prior art.

[0036] like Figure 2 and Figure 3 As shown, in the technical solution of the embodiment of the present application, the hollow structure 12 includes a guide section 121 and a profiling section 122, the profiling section 122 is connected to the first profiling surface 11, the guide section 121 is connected to the profiling section 122 and is arranged away from the first profiling surface 11, and the cross-sectional shape of the profiling section 122 is consistent with the shape of the area to be sprayed. After the ink enters the profiling section 122, it is distributed on the glass according to the cross-sectional shape of the profiling section 122. The profiling section 122 blocks the ink and prevents the ink from flowing to the area on the glass that does not need to be sprayed. The setting of the guide section 121 increases the opening area of ​​the hollow structure 12 away from the glass, which facilitates the ink to enter the profiling section 122.

[0037] like Figure 2 and Figure 3 As shown, in the technical solution of the embodiment of the present application, the cross-sectional area of ​​the guide section 121 increases continuously in the direction from approaching to away from the contour section 122. This avoids ink accumulation in the guide section 121 and facilitates the ink to flow into the contour section under the action of gravity.

[0038] like Figure 3As shown, in the technical solution of the embodiment of the present application, the first jig assembly 10 further includes a third profiling surface 13, the third profiling surface 13 is consistent with the shape of the second side surface of the glass to be sprayed, and the third profiling surface 13 is arranged on the side of the first jig assembly 10 away from the second jig assembly 20. Processing the side of the first jig assembly 10 away from the glass into a profiling surface effectively reduces consumables, saves costs, and reduces the quality of the first jig assembly 10, which is convenient for staff to operate.

[0039] like Figure 5 As shown, in the technical solution of the embodiment of the present application, the second fixture assembly 20 also includes a limiting portion 22, which is arranged corresponding to the second profiling surface 21, and the height of the upper surface of the limiting portion 22 in the vertical direction is higher than the height of the second profiling surface 21 in the vertical direction. The setting of the limiting portion 22 facilitates the staff to position and place the glass to be sprayed. After the glass is placed on the second profiling surface 21, the glass is moved until the side wall of the glass abuts against the side wall of the limiting portion 22, and the positioning of the glass is completed, thereby avoiding the problem of inaccurate ink spraying position due to position deviation when the glass is placed.

[0040] like Figure 5 As shown, in the technical solution of the embodiment of the present application, the height difference between the upper surface of the limiting portion 22 and the second profiling surface 21 in the vertical direction is greater than the thickness of the glass to be sprayed. The first fixture component 10 has a limiting groove that is consistent with the shape of the limiting portion 22. When the first fixture component 10 and the second fixture component 20 are matched, the sum of the depth of the limiting groove and the thickness of the glass to be processed in part of the limiting groove of the limiting portion 22 is equal to the height difference between the upper surface of the limiting portion 22 and the second profiling surface 21 in the vertical direction. At this time, when the first fixture component 10 and the second fixture component 20 are matched, the first profiling surface 11 is in contact with the upper surface of the glass and no indentation is generated on the glass surface. Figure 5 As shown, in the technical solution of the embodiment of the present application, the side of the limiting portion 22 close to the second profiling surface 21 is consistent with the side shape of the glass to be sprayed. The limiting portion 22 includes a first profiling segment and a second profiling segment, and the side walls of the first profiling segment and the second profiling segment are processed according to the shape of the adjacent two side walls of the glass to be sprayed, so that the above-mentioned two side walls are fitted with the limiting portion 22 to ensure the positioning accuracy of the glass and avoid the problem of poor product quality after spraying due to inaccurate position of the glass when it is placed.

[0041] like Figure 5As shown, in the technical solution of the embodiment of the present application, there is a second groove between the limiter 22 and the second profiling surface 21, and the height of the bottom of the second groove in the vertical direction is lower than the height of the second profiling surface 21 in the vertical direction. The second groove is arranged to avoid the contact between the edge of the glass and the angle between the limiter 22 and the second profiling surface 21, and effectively protects the edge of the glass from being damaged. The width of the second groove is 5mm to 30mm. When the width of the second groove is less than 5mm, the groove width is small and difficult to process; when the groove width is greater than 30mm, the glass exceeds the second profiling surface 21 by a large size, and under the action of gravity, the contact position between the glass and the edge of the second profiling surface 21 is prone to indentation, affecting the surface quality of the glass.

[0042] like Figure 1 and Figure 2 As shown, in the technical solution of the embodiment of the present application, the first fixture assembly 10 has a first connection portion 14, which is arranged on the circumferential outer side of the first profiling surface 11, and the second fixture assembly 20 has a second connection portion 23, which is arranged on the circumferential outer side of the second profiling surface 21. The first connection portion 14 and the second connection portion 23 are arranged correspondingly, and the first connection portion 14 has a spraying state of being sleeved on the second profiling surface 21 and a state to be sprayed away from the second profiling surface 21. When the first fixture assembly 10 and the second fixture assembly 20 are matched, the first connection portion 14 and the second connection portion 23 are arranged in a close fit, and the first connection portion 14 is sleeved on the second profiling surface 21 and the outer side of the glass. The inner side wall of the first connection portion 14 limits the glass, preventing the glass from shifting during the spraying process, and further ensuring the accuracy of the spraying position.

[0043] like Figure 1 and Figure 2 As shown, in the technical solution of the embodiment of the present application, a groove 231 is provided on the second connecting portion 23, and the groove 231 is located on the side of the second fixture assembly 20 away from the connection between the second fixture assembly 20 and the first fixture assembly 10. The setting of the groove 231 allows a gap to exist between the first connecting portion 14 and the second connecting portion 23 when the first connecting portion 14 is sleeved on the outside of the second contoured surface 21, so that the staff can lift the first connecting portion 14 to take out the glass. The exposure, development and spraying fixture also includes a driving component, and the driving component uses a pneumatic rod, the first end of the pneumatic rod is rotatably connected to the first fixture assembly 10, and the second end of the pneumatic rod is rotatably connected to the second fixture assembly 20. The pneumatic rod itself has a telescopic structure, and the setting of the pneumatic rod can reduce the force required by the staff to open and close the first fixture assembly 10, thereby reducing the difficulty of operation.

[0044] In order to further fix the position of the glass on the second profiling surface 21, the second profiling surface 21 is provided with a first negative pressure groove, a second negative pressure groove and a negative pressure hole. The negative pressure hole is arranged at the center of the second profiling surface 21. The first negative pressure groove includes a plurality of first negative pressure grooves, which are distributed in a ring shape with the negative pressure hole as the center. The second negative pressure groove includes a plurality of second negative pressure grooves, the first ends of which are connected to the negative pressure hole. The second negative pressure groove runs through the plurality of first negative pressure grooves and the second ends are connected to the first negative pressure grooves of the outermost circle. The angles between the plurality of second negative pressure grooves are the same. In the direction from approaching to away from the negative pressure hole, the spacing between adjacent first negative pressure grooves is continuously reduced. The above structure ensures that the adsorption force on the glass is uniform, and avoids local stress on the glass, which affects the product quality. A sealing groove is provided on the side of the profiling section 122 away from the guide section 121. A rubber sealing ring is provided in the sealing groove. The inner wall shape of the sealing ring is consistent with the shape of the area to be sprayed, which avoids the ink flowing from the profiling section 122 and the glass to the non-spraying area of ​​the glass when the glass is adsorbed by negative pressure, which affects the spraying effect.

[0045] like Figure 6 As shown, according to another aspect of the present application, an ink sprayer is provided, the ink sprayer adopts the above-mentioned exposure and development spraying jig, the ink sprayer includes a frame, and the second jig assembly 20 is connected to the frame. After the glass is placed, the exposure and development spraying jig is placed on the frame of the ink sprayer for spraying, and after the spraying is completed, it undergoes curing, cleaning, exposure and development and other processes to complete the glass processing.

[0046] In summary, the yellow light spraying jig (exposure and development spraying jig) of the present application is composed of two parts: a base (a second jig assembly 20) and a flip cover (a first jig assembly 10). It is mainly used in the yellow light process of 3D cover glass production, and can also be used in products of other products of yellow light process. The base is designed according to the 3D glass cover produced, and the base contact surface (the second profiling surface 21) is closely attached to the glass and wraps part of the edge of the cover glass to facilitate positioning. The inner surface of the flip cover (the first profiling surface 11) is designed according to the inner contour of the glass cover, and can completely wrap the glass after being combined with the base. A hollow groove (hollow structure 12) is provided on the flip cover, and the size and position of the groove correspond to the size and position of the ink sprayed on the cover glass. The flip cover is connected to the base through a hinge, and the flip cover can move freely according to the axis of the hinge after the two are combined. Furthermore, a groove (groove 231) is provided on the base to facilitate the lifting of the flip cover. The base and the flip plate are designed with gas pressure rods to reduce the force used when flipping. After the two are combined, they are placed on the spray rack (rack) and sprayed in the water curtain cabinet. When processing the flip cover, the upper surface of the 3D cover glass is profiled, and the parts that need to be sprayed with ink locally are opened according to the patterns, positioning lines and other parts required by the customer's drawings. The base is profiled according to the 3D cover glass and the side avoidance grooves are opened. It can be selected whether to add vacuum adsorption according to the actual situation. When the fixture is used, first lift the flip cover, place the glass on the base, and use the profiling edge (limiting part 22) to put the glass in place. Then close the flip cover and use the holes opened on the flip cover to spray specific areas of the glass to avoid ink splashing to areas that do not need exposure and development. Through the use of yellow light spraying fixtures, the purpose of reducing ink consumption, improving product yield and reducing production costs can be achieved.
