Currently, many attachment and assembly processes are completed by attachment equipment. The attachment equipment in the prior art places the display screen product on the attachment platform, and then directly uses a robotic arm mechanism to grab the sheet material and attach it to the display screen product on the attachment platform.

The operator presses the adsorption switch corresponding to the flip conveyor mechanism. The flip conveyor mechanism adsorbs the display screen product. The operator then tears off the film.

Simultaneously, the attachment roller and the film-tearing adsorption mechanism move together with the lifting frame. When the film-tearing adsorption mechanism moves to the position where the sheet material is adsorbed, the attachment roller also moves to the starting position for rolling and adhering the sheet material, resulting in high work efficiency.

[0048] The terms "first" and "second" in the present invention are used for descriptive purposes only and should not be understood as indicating or implying relative importance, and should not be used as a limitation on the order of precedence.

[0049] In the present invention, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be understood broadly. For example, connection can be a detachable connection or an integral structural connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be internal communication between two components or an interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0050] The attaching equipment in the prior art has technical problems of poor attaching effect and low working efficiency.

[0051] The following is a preferred embodiment of a mesh cage attaching device for display screen products provided by the present invention that can solve the above technical problems.

[0052] Please refer to Figure 1 and Figure 2 In the figures, units with similar structures are represented by the same reference numerals.

[0053] This embodiment provides a mesh cage attaching device for display screen products, which includes: a base 11, a flipping and conveying mechanism 12, a mesh cage attaching mechanism 13, an air suction mechanism 18, an ion wind rod 14, an alignment adjustment platform 1A, a lower positioning camera group 17, and an upper positioning camera group 15.

[0054] The alignment adjustment platform 1A is lifted and lowered on the base 11. The alignment adjustment platform 1A can be a UVW adjustment platform commonly used in the prior art. The cage attaching mechanism 13 is set on the alignment adjustment platform 1A. The flipping conveying mechanism 12 is slidably set on the base 11. The flipping conveying mechanism 12 includes a flipping platform, such as Figure 2 The rotation axis of the middle flip platform is parallel to the sliding direction of the flip conveying mechanism 12 and is located in the middle of the flip platform. The flip platform is flipped by a flip driving module 121 (which may be a motor).

[0055] One side of the flipping platform serves as a receiving surface for the display screen product Y. The flipping conveyor mechanism 12 includes a receiving position and an attachment position along its sliding path. When in the attachment position, the flipping conveyor mechanism 12 is located above the mesh attachment mechanism 13, with the receiving surface facing the mesh attachment mechanism 13. The mesh attachment mechanism 13 then rises to allow sheet material attachment. When in the receiving position, the flipping conveyor mechanism 12 is offset from the mesh attachment mechanism 13. This allows the flipping conveyor mechanism 12 to rotate without interfering with the mesh attachment mechanism 13. The receiving surface faces upward, facilitating placement of the display screen product Y and film removal.

[0056] Lower positioning camera assembly 17 is located below the sliding track of flip conveyor mechanism 12, while upper positioning camera assembly 15 is located above cage attachment mechanism 13. Alignment adjustment platform 1A adjusts the position of cage attachment mechanism 13 based on the image data from lower and upper positioning camera assembly 17, 15, thereby achieving proper alignment between sheet material X and display product Y.

[0057] An ion wind bar 14 is provided on one side of the flip conveying mechanism 12 and the net box attaching mechanism 13. The ion wind bar 14 is used to blow air to clean and eliminate static electricity on the display screen product and the sheet material after the film is torn.

[0058] Please refer to Figure 3 The mesh box attaching mechanism 13 in this embodiment includes an attaching roller 132, a mesh box body 131, and a film tearing adsorption mechanism 133. The suction end of the suction mechanism 18 is connected to the inner cavity of the mesh box body 131. The top surface of the mesh box body 131 is an adsorption opening and a gauze is provided on the adsorption opening. The gauze is used to carry the sheet material X. The suction mechanism 18 vacuums the inner cavity of the mesh box body 131 and then adsorbs the sheet material X through the mesh holes of the gauze. The sheet material X can be a sheet product such as a polarizer, an OCA film, or a protective film.

[0059] The film-tearing suction mechanism 133 is disposed within the mesh box body 131, and the attachment roller 132 is slidably and elevatingly disposed within the mesh box body 131. The attachment roller 132 is parallel to the plane of the suction opening, and its sliding direction is parallel to the plane of the suction opening. The lifting and lowering directions of the film-tearing suction mechanism 133 and the attachment roller 132 intersect the plane of the suction opening. The attachment roller 132, through transverse movement and elevation, rolls and affixes the sheet X to the display product Y attached to the flipping and conveying mechanism 12. The film-tearing suction mechanism 133 is used to absorb the sheet X from the gauze to facilitate film tearing. The film-tearing suction mechanism 133 absorbs a corner of the sheet X and secures it. The operator begins tearing the film from the corner of the sheet X attached by the film-tearing suction mechanism 133, which prevents the sheet X from shifting, thereby improving the subsequent attachment effect and efficiency.

[0060] The moving position of the attaching roller 132 can be detected by providing a corresponding sensor.

[0061] In addition, a foreign object lamp 16 is provided on one side of the base 11. The foreign object lamp 16 is located on the upper side of the flip conveying mechanism 12. The foreign object lamp 16 shines light toward the material receiving surface of the flip conveying mechanism 12. After illumination, the operator can better observe whether there are foreign objects on the display screen product Y so as to wipe and clean the display screen product Y.

[0062] Please refer to Figure 3 and Figure 4 Specifically, the cage attachment mechanism 13 further includes a sliding frame 135, a lifting frame 136, a first linear drive module 134, and an attachment lifting cylinder 137. The first linear drive module 134 can be, but is not limited to, a motor screw mechanism, a linear motor, and the like.

[0063] The sliding frame 135 is connected to the output end of the first linear drive module 134, the lifting frame 136 is slidingly connected to the sliding frame 135, two attachment lifting cylinders 137 are respectively arranged at both ends of the sliding frame 135, the lifting frame 136 is connected to the output end of the attachment lifting cylinder 137, and the attachment roller 132 is arranged on the top of the lifting frame 136.

[0064] The film tearing adsorption mechanism 133 includes a film tearing lifting cylinder 1331 and a suction plate 1332 . The film tearing lifting cylinder 1331 is connected to one side of the lifting frame 136 , and the suction plate 1332 is connected to the output end at the top of the film tearing lifting cylinder 1331 .

[0065] Please refer to Figure 5 , wherein the lifting frame 136 includes a sliding plate 1361, a connecting plate 1362, a mounting plate 1363, a mounting block 13C1, a supporting screw 13C, a rotating shaft screw 13D, a mounting screw, and a screw fine-tuner 13F.

[0066] The sliding frame 135 includes a bottom plate and side plates vertically connected to the bottom plate ( Figure 4The number 135 in the middle refers to the side panel), and the sliding plate 1361 is slidably connected to one side of the side panel to enable the lifting frame 136 to slide and rise and fall. The pivot screw 13D passes through the middle of the connecting plate 1362 and is connected to the sliding plate 1361. The mounting block 13C1 is fixedly set on the side of the sliding plate 1361 close to the connecting plate 1362. The two mounting blocks 13C1 are symmetrically arranged on both sides of the pivot screw 13D. The support screw 13C passes through the mounting block 13C1 and forms a threaded connection. The support screw 13C contacts the bottom surface of the connecting plate 1362. A long hole 13E is provided on the connecting plate 1362. At least two long holes 13E are symmetrically arranged on both sides of the pivot screw 13D. The mounting screw passes through the long hole 13E and is threadedly connected to the sliding plate 1361. The mounting plate 1363 is connected to the top surface of the connecting plate 1362. The attachment roller 132 is arranged on the mounting plate 1363. The axial direction of the support screw 13C is perpendicular to the axial direction of the attachment roller 132.

[0067] The screw fine adjuster 13F is fixedly connected to one side of the sliding plate 1361 . The screw fine adjuster 13F includes a fine adjustment screw in contact with the bottom surface of the mounting plate 1363 . The axial direction of the fine adjustment screw is parallel to the sliding direction of the lifting frame 136 .

[0068] When installing the lifting frame 136, first install the mounting block 13C1 and the supporting screw 13C, and then connect the connecting plate 1362 and the sliding plate 1361 through the mounting screws and the rotating shaft screw 13D. At this time, the mounting screws and the rotating shaft screw 13D do not need to be fully tightened, and the supporting screw 13C supports the connecting plate 1362. The connecting plate 1362 is squeezed by screwing the supporting screws 13C at both ends to perform leveling operation. After leveling, tighten the mounting screws and the rotating shaft screw 13D a little, and then screw the spiral fine-tuner 13F to perform more fine leveling on the connecting plate 1362. After leveling again, further tighten the mounting screws and the rotating shaft screw 13D completely, so that the installation accuracy of the attachment roller 132 is very high, the attachment roller 132 is very flat relative to the sheet, and the subsequent attachment effect is good.

[0069] Please refer to Figure 4 In this embodiment, the lifting frame 136 further includes a limit block 139 and a limit screw 13A. The limit block 139 is connected to the sliding plate. The limit block 139 extends through the side plate to the side away from the sliding plate. An extension plate 13B is provided on the top of the side plate. The limit screw 13A extends through the extension plate 13B and forms a threaded connection. The limit block 139 is located on the axial extension line of the limit screw 13A. The contact between the limit block 139 and the limit screw 13A limits the upward travel of the attachment roller 132, preventing the attachment roller 132 from rising too far and damaging the display product Y.

[0070] In addition, two support rollers 138 are provided between the mounting plate and the attaching roller 132. The support rollers 138 are parallel to the attaching roller 132 and are symmetrically in contact with both sides of the attaching roller 132. This can eliminate the installation gap of the attaching roller 132 and improve the attaching effect of the attaching roller 132.

[0071] Please refer to Figure 8 In this embodiment, when the sheet X is placed on the screen, the screen has exposed areas not covered by the sheet X. All four sides of the sheet X have exposed areas. The screen box attachment device for display products also includes adhesive tape 1B, which is attached to some of the exposed areas. This creates a balance between suction and air leakage, preventing the screen box body 131 from excessively sucking the sheet X and causing the screen to sag. This ensures smooth suction of the sheet and improves the attachment effect.

[0072] Optionally, suction ports connected to the suction ends of the suction mechanism 18 may be provided on opposite sides of the cage body 131. Each side of the cage body 131 is connected to a corresponding suction mechanism 18, or both sides of the cage body 131 are connected to the two suction ends of the same suction mechanism 18. This can improve the uniformity of vacuum suction of the sheet material within the cage body 131. The exposed area where the tape 1B is not attached is the leakage area 1B1. The area of the leakage area 1B1 gradually decreases from closer to the suction port toward farther away from the suction port, thereby improving the uniformity of sheet material suction.

[0073] Please refer to Figure 3 and Figure 6 In this embodiment, the mesh box attaching device for display screen products further includes a lifting mechanism 19 .

[0074] The lifting mechanism 19 includes a fixed frame 191, a lifting frame 192, a second linear drive module 193, a sliding seat 194, and a connecting block 195. The second linear drive module 193 can be, but is not limited to, a motor screw mechanism, a linear motor, or the like.

[0075] The two sides of the lifting frame 192 are slidably connected to the fixed frame 191, and corresponding slider rail structures 1911 are provided between the two sides of the lifting frame 192 and the fixed frame 191. The second linear drive module 193 and the sliding seat 194 are located between the lifting frame 192 and the fixed frame 191. The second linear drive module 193 is fixedly set on the fixed frame 191, and the sliding seat 194 is slidably set on the fixed frame 191. The sliding seat 194 is connected to the output end of the second linear drive module 193. The sliding seat 194 is provided with an inclined guide rail 196. The extension direction of the inclined guide rail 196 is inclined at an angle of 5°-30° with the sliding plane of the sliding seat 194. The connecting block 195 is fixedly connected to the lifting frame 192 and is slidably connected to the inclined guide rail 196.

[0076] The alignment adjustment platform 1A is connected between the cage attaching mechanism 13 and the lifting frame 192 , and the fixed frame 191 is connected to the base 11 .

[0077] In this way, the second linear drive module 193 drives the sliding seat 194 to move, thereby pushing the lifting frame 192 up and down. The lifting mechanism 19 has a strong carrying capacity and can stably carry the alignment adjustment platform 1A and the net box attachment mechanism 13. The lifting drive is more stable and can also improve the sheet attachment effect.

[0078] Please refer to Figure 2 and Figure 7 In this embodiment, the air suction mechanism 18 includes a fan 181, an air suction pipe 182, an on-off control valve 183, a pressure relief valve 184, and an exhaust pipe 185.

[0079] The switch control valve 183 is connected to the suction end of the fan 181, the suction pipe 182 and the pressure relief valve 184 are respectively connected to different ports of the switch control valve 183, the suction pipe 182 is connected to the inner cavity of the cage body 131, and the exhaust end of the fan 181 is connected to the external space of the cage body 131 through the exhaust pipe 185.

[0080] It takes a long time for the fan 181 to start up and reach a stable output. In this embodiment, the net box body 131's suction of the sheet material is turned on or off by the on-off control valve 183, without stopping the fan 181, thereby improving work efficiency. Furthermore, by providing a pressure relief valve 184, when the on-off control valve 183 closes the suction pipe 182, the pressure is released through the pressure relief valve 184. This prevents the suction end of the fan 181 from being completely blocked by the closure of the on-off control valve 183, thus preventing the fan 181 from overheating and damaging.

[0081] The fan 181 may be provided with a frequency converter, and the frequency converter may be used to control the fan 181 to output wind forces of different magnitudes.

[0082] In addition, a filter 186 is connected between the fan 181 and the suction pipe 182, which makes it cleaner and prevents the inside of the fan from being easily dirty or damaged.

[0084] The first transverse frame 153 is connected to the output end of the first X-direction moving module 171 , the first lower positioning camera 174 and the first Y-direction moving module 172 are set on the first transverse frame 153 , and the second lower positioning camera 175 is connected to the output end of the first Y-direction moving module 172 .

[0085] In this way, the first lower positioning camera 174 can move along the X direction, and the second lower positioning camera 175 can move along the X direction and the Y direction, so that the lower positioning camera group 17 can take pictures of the four corners of display screen products of different sizes.

[0086] The upper positioning camera assembly 15 includes a second X-direction moving module 151 , a second Y-direction moving module 152 , a second transverse moving frame 173 , a first upper positioning camera 154 and a second upper positioning camera 155 .

The first upper positioning camera 154 and the second Y-direction moving module 152 are arranged on the second transverse frame 173 . The second upper positioning camera 155 is connected to the output end of the second Y-direction moving module 152 .

[0088] In this way, the first upper positioning camera 154 can move along the X direction, and the second upper positioning camera 155 can move along the X direction and the Y direction, so that the upper positioning camera group 15 can take pictures of the four corners of sheets of different sizes.

[0089] Please refer to Figure 9 The present invention also includes a method for attaching a sheet material X to a display screen product Y using the above-mentioned mesh box attaching device, the attaching method comprising the following steps:

[0090] Step S11: With the flip conveyor mechanism 12 positioned at the receiving position, the operator places the display screen product Y onto the receiving surface of the flip conveyor mechanism 12, which is provided with suction holes for adsorbing the display screen product Y. The operator presses the corresponding suction switch on the flip conveyor mechanism 12, causing the flip conveyor mechanism 12 to absorb the display screen product Y. The operator then removes the film from the display screen product Y. After removal, the ion air bar 14 blows air to clean and eliminate static electricity from the removed display screen product Y.

[0091] In addition, the display screen product Y is illuminated by the foreign object lamp 16, and the operator can observe and wipe the display screen product Y to clean it.

[0092] Step S12: The conveyor mechanism 12 is flipped 180°, and the lower positioning camera assembly 17 takes photos of the display screen product Y. Specifically, under a preset program, the first lower positioning camera 174 moves along the X direction, and the second lower positioning camera 175 moves along the X and Y directions, so that the lower positioning camera assembly 17 takes photos of the four corners of the display screen product.

[0093] Step S13: The operator applies adhesive tape 1B to the exposed area of the gauze according to the size specifications of the sheet X. The operator then places the sheet X onto the gauze of the mesh box body 131. The operator presses the corresponding suction switch on the mesh box body 131, causing the suction mechanism 18 to activate and communicate with the inner cavity of the mesh box body 131, allowing the mesh box body 131 to absorb the sheet X. The operator does not need to reapply adhesive tape 1B for subsequent attachment of sheets of the same size. The operator simply controls the opening and closing of the on / off control valve 183 to turn the mesh box body 131's suction on the sheet X on and off, while the fan 181 continues to operate, improving work efficiency.

[0094] The attaching roller 132 and the film tearing adsorption mechanism 133 move to the set position, the film tearing adsorption mechanism 133 rises to attract the sheet X, and then the operator tears the film from the sheet X. After the film is torn, the ion wind bar 14 blows air to clean and eliminate static electricity on the torn sheet X.

[0095] Step S14: The operator presses the attachment switch, and the upper positioning camera group 15 takes a picture of the sheet X for positioning. The alignment adjustment platform 1A adjusts the position of the cage body 131 according to the picture information of the lower positioning camera group 17 and the upper positioning camera group 15, thereby achieving the alignment of the sheet X and the display product Y.

[0096] Step S15: The flipping conveyor mechanism 12 moves to the attachment position, the mesh cage attachment mechanism 13 rises a set distance and then stops, the film tearing and adsorption mechanism 133 descends, and the attachment roller 132 rises. The attachment roller 132 moves to roll and adhere the sheet X to the display product Y adsorbed by the flipping conveyor mechanism 12. As the attachment roller 132 moves and rolls the sheet X, the speed of the attachment roller 132 gradually increases to prevent the initial speed of the attachment roller 132 from being too high, which could cause the sheet to be attached out of position. Specifically, the attachment roller 132 may move at a constant speed for a set distance and then decelerate once until the sheet is fully attached.

[0097] The net cage body 131 gradually reduces its suction force on the sheet X until it is completely shut off. This prevents excessive suction force from affecting the adhesion process. Specifically, the fan 181 can be controlled by a frequency converter to output varying wind speeds, thereby varying the suction force of the net cage body 131. The suction mechanism 18 continues operating, and then the suction force of the net cage body 131 is shut off by controlling the on / off control valve 183.

[0098] Step S16: the sheet material X is attached to the display screen product Y, the mesh box attaching mechanism 13 descends, the flipping and conveying mechanism 12 moves and flips to reach the material receiving position, and the operator takes away the attached product.

[0099] Then the sheet attachment work of the next display product can be carried out again in a cycle.

[0100] The mesh cage attachment device of this embodiment incorporates a film-tearing suction mechanism that works alongside the mesh cage body to absorb the sheet material. This ensures stable sheet absorption, preventing the sheet material from shifting due to the film-tearing operation, thereby improving subsequent attachment effectiveness and efficiency. The attachment roller and the film-tearing suction mechanism simultaneously move with the lifting frame. When the film-tearing suction mechanism reaches the sheet absorption position, the attachment roller also moves to the starting position for rolling and attaching the sheet material, resulting in high operational efficiency. Furthermore, the suction mechanism uses a switch control valve to open and close the mesh cage body's absorption of the sheet material, while the fan continues to operate, thereby improving operational efficiency.

[0101] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
