[0040] Referring to Figures 1 to 3 An embodiment of the present application provides a curved surface fitting device comprising a mounting module 10 and a pressing module 300. Referring to Figures 3 to 5The mounting module 10 comprises a bearing mechanism 100 and a clamping mechanism 200. The bearing mechanism 100 has a bearing curved surface protruding towards a first direction, which is used to abut the concave side of the curved cover plate 500 and bear and fix the curved cover plate 500. The clamping mechanism 200 is used to clamp the display screen 600 transported to one side of the curved cover plate 500 along the first direction. Referring to Figures 1 to 4 The pressing module 300 is located at one side of the mounting module 10 along the first direction. The pressing module 300 comprises a pneumatic pressing head 310 and a pressing driving member 320 connected with each other. The pneumatic pressing head 310 can protrude towards a second direction in an inflated state. The pressing driving member 320 is used to drive the pneumatic pressing head 310 to move towards the second direction, so that the pneumatic pressing head 310 presses the display screen 600 to the curved cover plate 500 from the center to the edge in sequence. The first direction is parallel to the vertical direction, and the second direction is opposite to the first direction.

[0041] In the above embodiment, the bearing curved surface of the bearing mechanism 100 is also a convex surface, which can abut the concave side of the curved cover plate 500 and bear and fix the curved cover plate 500, so that the position of the curved cover plate 500 is fixed and it will not be displaced relative to the display screen 600 during the abutting process. The pressing module 300 is located at one side of the mounting module 10 along the first direction, and the pneumatic pressing head 310 protrudes towards the second direction in the inflated state, i.e. the pneumatic pressing head 310 protrudes towards the side where the display screen 600 and the curved cover plate 500 are located in the inflated state, i.e. the protruding direction of the pneumatic pressing head 310 is opposite to the protruding direction of the bearing curved surface and the curved cover plate 500. Therefore, when the pressing driving member 320 drives the pneumatic pressing head 310 to gradually approach the display screen 600, the pneumatic pressing head 310 can gradually transition from point contact to surface contact with the display screen 600 from a small area, so that the display screen 600 and the curved cover plate 500 also gradually transition from point contact to surface contact, thereby realizing the pressing of the display screen 600 to the curved cover plate 500 from the center to the edge in sequence. Compared with the prior art in which the bearing curved surface and the profiled silicone pressing head protrude in the same direction according to the profile of the curved cover plate 500, the design of the present application realizes the pressing of the display screen 600 to the curved cover plate 500 from the center to the edge in sequence, avoids the pressing of the entire surface of the display screen 600 to the curved cover plate 500 during the pressing process, and thus can gradually drive out the air bubbles during the gradual abutting process, improve the flatness after abutting, and reduce the product failure rate.

[0042] In the embodiment shown in the drawings, the first direction is a vertically upward direction, i.e., a direction from bottom to top; and the second direction is a vertically downward direction, i.e., a direction from top to bottom. In this way, the curved cover plate 500 can be directly placed on the bearing curved surface of the bearing mechanism 100 and positioned, without the need for additional fixing members to overcome the separation of the curved cover plate 500 from the bearing curved surface under the action of gravity. Of course, in other embodiments, the first direction can also be a vertically downward direction. At this time, additional fixing members are needed to fix the curved cover plate 500 to the bearing curved surface of the bearing mechanism 100 to overcome the falling of the curved cover plate 500 under the action of gravity. In subsequent embodiments, the direction of the embodiment shown in the drawings will be introduced.

[0043] Referring to Figures 1 to 4 In the embodiment shown in the drawings, the bearing mechanism 100 has a bearing curved surface that protrudes upward, which is used to fit with the concave side of the bottom end of the curved cover plate 500 and bear and fix the curved cover plate 500, and the clamping mechanism 200 is used to clamp the display screen 600 transported above the curved cover plate 500. The compression module 300 is located above the mounting module 10, and the air bag pressing head 310 can protrude downward in the inflated state, and the compression driving member 320 is used to drive the air bag pressing head 310 to move downward.

[0044] Referring to Figures 3 to 5 In the embodiment shown in the drawings, the bearing mechanism 100 includes a bearing jig 110 and a negative pressure suction accessory, and the bearing jig 110 has a bearing curved surface that protrudes upward, and the bearing curved surface is provided with suction holes that are communicated with the negative pressure suction accessory.

[0045] Specifically, the negative pressure suction accessory can be a vacuum pump or other component capable of providing suction force. The bearing mechanism 100 further includes a bearing seat 120 for supporting the bearing jig 110, and the bearing jig 110 is located on the top of the bearing seat 120. The top surface of the bearing jig 110 protrudes upward to form the bearing curved surface, i.e., the top surface of the bearing jig 110 is the bearing curved surface. The shape and size of the bearing curved surface are matched with the curved cover plate 500, so that when the curved cover plate 500 is placed on the bearing curved surface, the two can be completely fitted, having high positional stability, so that the curved cover plate 500 is not easy to shift. The bearing curved surface is provided with suction holes, and suction force is provided by the negative pressure suction accessory, so that the curved cover plate 500 can be suctioned and fixed on the bearing curved surface to inhibit shifting.

[0046] In some embodiments, a baffle or other component can also be provided at the edge of the bearing curved surface. When the curved cover plate 500 is placed on the bearing curved surface, the baffle can be quickly positioned to facilitate quick placement of the curved cover plate 500 in place.

[0047] Referring to Figures 1 to 4In some embodiments, the curved surface fitting device comprises a driving module 400 configured to drive the relative movement of the mounting module 10 and the pressing module 300, so that the projection of the convex top point of the air bag pressing head 310 and the convex top point of the curved surface cover plate 500 along the first direction coincide.

[0048] In the embodiment shown in the drawings, the driving module 400 is connected to the mounting module 10 and configured to drive the mounting module 10 to move along the third direction, so that the projection of the convex top point of the air bag pressing head 310 and the convex top point of the curved surface cover plate 500 along the first direction coincide, wherein the third direction is perpendicular to the first direction.

[0049] Further, the driving module 400 comprises a positioning driving member 410, a lead screw 420 extending along the third direction and connected to the power output end of the positioning driving member 410, and a nut member sleeved outside the lead screw 420 and threadedly connected thereto, and the nut member is further connected to the mounting module 10. The positioning driving member 410 is configured to drive the lead screw 420 to rotate around the third direction, so as to drive the nut member and the mounting module 10 to move along the third direction.

[0050] Specifically, the mounting module 10 comprises a lower cavity seat 11, and the nut member is fixedly connected to the lower cavity seat 11. The projection of the convex top point of the air bag pressing head 310 and the convex top point of the curved surface cover plate 500 along the first direction coincide, that is, the bottom end of the air bag pressing head 310 and the top end of the curved surface cover plate 500 coincide in projection on the horizontal plane, that is, the bottom end of the air bag pressing head 310 is just located directly above the top end of the curved surface cover plate 500. In this way, it can be ensured that the display screen 600 and the curved surface cover plate 500 gradually transition from point contact to surface contact when the air bag pressing head 310 is pressed down, and the display screen 600 is sequentially pressed and fitted to the curved surface cover plate 500 from the center to the edge.

[0051] The third direction is located in the horizontal plane, and the positioning driving member 410 is selected as a motor which can drive the mounting module 10 to move along the third direction in the horizontal plane to be located directly below the pressing module 300, so that the bottom end of the air bag pressing head 310 is just located directly above the top end of the curved surface cover plate 500.

[0052] Referring to Figures 1 to 4 In some embodiments, a first sliding block 12 is arranged on the lower cavity seat 11, and a first sliding rail 13 is connected to the frame of the entire curved surface fitting device, and the first sliding block 12 is slidingly installed on the first sliding rail 13 along the third direction, so as to improve the stability of the mounting module 10 during movement. In other embodiments, the positions of the first sliding block 12 and the first sliding rail 13 can be interchanged.

[0053] Referring to Figures 4 to 6In some embodiments, the clamping mechanism 200 includes two sets of clamping assemblies 210, which are respectively arranged on two sides of the bearing mechanism 100 along the fourth direction. Each set of clamping assemblies 210 includes a clamping jaw 212 and a base 211. The two sets of clamping jaws 212 are respectively used to clamp the display screen 600 at two ends along the fourth direction. In each set of clamping assemblies 210, the clamping jaw 212 is elastically connected to the base 211 along the fourth direction. The fourth direction is perpendicular to the first direction.

[0054] In the embodiment shown in the drawings, the fourth direction is also in the horizontal plane and is perpendicular to the third direction. In other embodiments, the fourth direction is parallel to the third direction, or the angle between the two directions is an acute angle / obtuse angle.

[0055] The display screen 600 is transported to above the curved cover plate 500 by a person or a mechanical arm, and the position of the display screen 600 relative to the curved cover plate 500 is adjusted. Then, the two sets of clamping jaws 212 are used to clamp and fix the display screen 600 at two ends along the fourth direction, so as to prepare for the subsequent bonding.

[0056] Meanwhile, referring to Figure 8 The display screen 600 includes a screen body 610 and a bearing film 620. The screen body 610 and the bearing film 620 are bonded together, and the outer end of the bearing film 620 extends to the outside of the screen body 610 along the fourth direction. The two sets of clamping jaws 212 clamp the bearing film 620 at two ends, so as to protect the screen body 610 from being damaged by being clamped.

[0057] Continuously referring to Figures 4 to 6 The two sets of clamping assemblies 210 are completely identical in structure and are symmetrically arranged on two sides of the bearing mechanism 100 along the fourth direction. In each set of clamping assemblies 210, the clamping jaw 212 is elastically connected to the base 211 along the fourth direction, that is, the clamping jaw 212 can elastically move along the fourth direction relative to the base 211. Understandably, when the display screen 600 is gradually pressed and bonded to the curved cover plate 500 by the air bag pressure head 310, the display screen 600 will be stretched and deformed to a certain extent along the fourth direction. In the above embodiment, since the clamping jaw 212 can elastically move along the fourth direction relative to the base 211, the stretching deformation of the display screen 600 along the fourth direction can be adapted, and the risk of the display screen 600 being torn is reduced.

[0058] Referring to Figures 4 to 6 In some embodiments, each set of clamping assemblies 210 includes a connecting frame 213 and a first elastic member 214 capable of elastically deforming along the fourth direction. The clamping jaw 212 is mounted on the corresponding connecting frame 213. The two ends of the first elastic member 214 are respectively connected to the corresponding connecting frame 213 and the base 211.

[0059] Specifically, the first elastic member 214 extends along the fourth direction, one end of which is hung on the first abutting seat 2131 in the connecting frame 213, and the other end of which is hung on the base 211. During the pressing process of the air bag pressure head 310, the edges of the display screen 600 will be deformed by being pulled towards the center, and the clamping jaw 212 and the connecting frame 213 connected thereto will move along the fourth direction towards the side close to the carrying fixture 110, and the first elastic member 214 will be continuously stretched to adapt to the tensile deformation of the display screen 600, thereby reducing the risk of the display screen 600 being torn.

[0060] Referring to Figures 4 to 6 In some embodiments, each set of clamping assemblies 210 includes a first adjusting member 215 which passes through the corresponding base 211 and abuts against the connecting frame 213, and the first adjusting member 215 is screw-connected to the corresponding base 211.

[0061] Specifically, the first adjusting member 215 is directly selected as a screw, one end of which abuts against the first abutting seat 2131 in the connecting frame 213 to inhibit the connecting frame 213 from moving along the fourth direction away from the carrying fixture 110 under the resilience of the first elastic member 214. After the two sets of clamping jaws 212 are clamped and fixed to the two ends of the display screen 600 along the fourth direction, the first adjusting member 215 can be rotated to adjust the position of the connecting frame 213 and the clamping jaw 212 along the fourth direction, thereby providing a more appropriate clamping tensile force to the display screen 600. For example, when the curvature of the curved cover plate 500 is large, the display screen 600 will produce a large deformation during the pressing process, and therefore the first adjusting member 215 can be rotated to reduce the distance between the two sets of clamping jaws 212 along the fourth direction, thereby reducing the clamping tensile force on the display screen 600, making it easy to deform during the pressing process, thereby reducing the risk of breakage.

[0062] Referring to Figures 4 to 6 In some embodiments, each set of clamping assemblies 210 includes a second elastic member 216 which can elastically deform along the first direction, two ends of the second elastic member 216 being connected to the corresponding clamping jaw 212 and the connecting frame 213, respectively.

[0063] Specifically, the clamping jaw 212 comprises an upper clamping part 2121 and a lower clamping part 2122 arranged along the first direction, and at least one of the two is connected to a clamping driving member 2123. The clamping driving member 2123 is used to drive the upper clamping part 2121 and the lower clamping part 2122 to fold or separate, and when the two are folded, the clamping and fixing of the display screen 600 can be realized. The second elastic member 216 extends along the first direction, one end of which is hung on the second abutting seat 2124 connected to the clamping driving member 2123, and the other end is hung on the connecting frame 213. When the display screen 600 is gradually pressed and attached to the curved cover plate 500 by the air bag pressing head 310, the display screen 600 will also produce a certain degree of tensile deformation along the first direction. In the above embodiment, because the second elastic member 216 is provided, during the pressing process of the air bag pressing head 310, the clamping jaw 212, the clamping driving member 2123 and the second abutting seat 2124 move downward, and the second elastic member 216 is continuously stretched to adapt to the tensile deformation of the display screen 600, thereby reducing the risk of the display screen 600 being torn.

[0064] Referring to Figures 4 to 6 In some embodiments, each set of clamping assemblies 210 comprises a second adjusting member 217, which passes through the corresponding connecting frame 213 and abuts against the clamping jaw 212, and the second adjusting member 217 is screw-connected to the corresponding connecting frame 213.

[0065] Specifically, the second adjusting member 217 is directly selected as a screw, one end of which abuts against the second abutting seat 2124 to inhibit the upward movement of the clamping jaw 212 and the clamping driving member 2123 under the elastic force of the second elastic member 216. After the two sets of clamping jaws 212 are respectively clamped and fixed to the display screen 600 at both ends along the fourth direction, the second adjusting member 217 can be rotated to adjust the height of the clamping jaw 212 and the display screen 600, so as to adapt to the curved cover plate 500 with different curvatures and reduce the risk of the display screen 600 being broken.

[0066] Referring to Figures 4 to 6 In some embodiments, the connecting frame 213 is slidingly fitted in the corresponding base 211 along the fourth direction, and the clamping jaw 212 is slidingly fitted in the corresponding connecting frame 213 along the first direction. In this way, the stability of the movement of the clamping jaw 212 along the first direction and the fourth direction during the stretching deformation of the display screen 600 during the pressing process can be improved.

[0067] Specifically, the connecting frame 213 is connected to a second sliding block 2132, the base 211 is connected to a second sliding rail 2111 extending in the fourth direction, and the second sliding block 2132 is slidingly installed on the second sliding rail 2111. The second abutting seat 2124 is connected to a third sliding block 2125, the connecting frame 213 is connected to a third sliding rail 2133 extending in the first direction, and the third sliding block 2125 is slidingly installed on the third sliding rail 2133. In other embodiments, the positions of the second sliding block 2132 and the second sliding rail 2111 can be interchanged, and the positions of the third sliding block 2125 and the third sliding rail 2133 can also be interchanged.
