[0002] As a display device that outputs images, the display screen has been widely used in many fields in recent years. Display screens have numerous components, and corresponding assembly processes are also numerous, such as attaching sheet components like polarizers, OCA films, and protective films to semi-finished display screens. Currently, many attachment and assembly processes are completed by attachment equipment. Existing attachment equipment places the display screen product on an attachment platform and then uses a robotic arm to directly pick up the sheet and attach it to the display screen product on the attachment platform. Factors such as film peeling operations during the attachment process causing sheet misalignment, poor installation accuracy of the attachment rollers, and poor coordination between sheet adsorption and adhesion force all affect the attachment effect and work efficiency. Existing attachment equipment suffers from technical problems of poor attachment effect and low work efficiency.

[0045] Existing bonding equipment suffers from technical problems such as poor bonding effect and low work efficiency.

[0046] The following is a preferred embodiment of a wire mesh attachment device for display screen products, which can solve the above-mentioned technical problems.

[0047] Please refer to Figure 1 and Figure 2 In the diagram, units with similar structures are represented by the same labels.

[0048] This embodiment provides a mesh cage attachment device for display screen products, which includes: a base 11, a flipping conveyor mechanism 12, a mesh cage attachment mechanism 13, an air suction mechanism 18, an ion air bar 14, an alignment adjustment platform 1A, a lower positioning camera group 17, and an upper positioning camera group 15.

[0049] The alignment adjustment platform 1A is raised 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 attachment mechanism 13 is mounted on the alignment adjustment platform 1A. Please refer to... Figure 2The flipping conveyor mechanism 12 is slidably mounted on the base 11. The flipping conveyor mechanism 12 includes a flipping frame 122, a flipping platform 123, and a flipping drive module 121. The flipping frame 122 is slidably mounted on the base 11, and the flipping platform 123 is rotatably mounted on the flipping frame 122. The rotating shaft of the flipping platform 123 is parallel to the sliding direction of the flipping conveyor mechanism 12 and is located in the middle of the flipping platform 123. The flipping drive module 121 is located in the middle of one side of the flipping frame 122. The rotating shaft of the flipping platform 123 is connected to the output end of the flipping drive module 121 for transmission. The flipping platform is driven to flip by the flipping drive module 121 (which may be a motor).

[0050] One side of the flipping platform is the receiving surface for adsorbing the display screen product Y. The flipping conveyor 12 includes a receiving position and an attachment position on its sliding trajectory. When the flipping conveyor 12 is in the attachment position, it is located above the wire mesh attachment mechanism 13, with the receiving surface facing the wire mesh attachment mechanism 13. The wire mesh attachment mechanism 13 can then rise to perform the sheet attachment work. When the flipping conveyor 12 is in the receiving position, it is misaligned with the wire mesh attachment mechanism 13. This prevents the flipping conveyor 12 from interfering with the wire mesh attachment mechanism 13 during flipping, and the receiving surface faces upwards, facilitating the placement of the display screen product Y and the film peeling operation.

[0051] The lower positioning camera group 17 is located below the sliding track of the flipping conveyor mechanism 12, and the upper positioning camera group 15 is located above the wire mesh attachment mechanism 13. The alignment adjustment platform 1A can adjust the position of the wire mesh attachment mechanism 13 according to the photographic information of the lower positioning camera group 17 and the upper positioning camera group 15, so as to achieve the alignment of the sheet X and the display product Y.

[0052] Both the flipping conveyor mechanism 12 and the wire mesh attaching mechanism 13 are equipped with ion air bars 14 on one side. The ion air bars 14 are used to blow air to clean and destaticate the display screen products and sheets after the film has been peeled off.

[0053] Please refer to Figure 3 In this embodiment, the wire mesh attachment mechanism 13 includes an attachment roller 132, a wire mesh 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 wire mesh body 131. The top surface of the wire mesh body 131 is an adsorption opening and a mesh is provided on the adsorption opening. The mesh is used to support the sheet X. The suction mechanism 18 draws a vacuum into the inner cavity of the wire mesh body 131 and then adsorbs the sheet X through the mesh opening. The sheet X can be a polarizing film, OCA film, protective film, or other sheet products.

[0054] The film-peeling adsorption mechanism 133 is lowered and installed inside the mesh box body 131. The attaching roller 132 is slidably and vertically installed inside the mesh box body 131. The attaching roller 132 is parallel to the plane of the adsorption opening, and the sliding direction of the attaching roller 132 is parallel to the plane of the adsorption opening. The vertical direction of the film-peeling adsorption mechanism 133 and the attaching roller 132 intersects the plane of the adsorption opening. The attaching roller 132 rolls and attaches the sheet X to the display screen product Y adsorbed by the flipping conveyor mechanism 12 through horizontal movement and vertical movement. The film-peeling adsorption mechanism 133 is used to adsorb the sheet X on the mesh for film peeling. The film-peeling adsorption mechanism 133 adsorbs one corner of the sheet X and adheres it firmly. The operator starts peeling the film from the corner of the sheet X adsorbed by the film-peeling adsorption mechanism 133. The sheet X is less likely to be misaligned, which can improve the subsequent adhesion effect and efficiency.

[0055] The movement position of the attaching roller 132 can be detected by setting a corresponding sensor.

[0056] In addition, a foreign object lamp 16 is provided on one side of the base 11. The foreign object lamp 16 is located above the flip conveyor 12 and shines light on the receiving surface of the flip conveyor 12. After shining the light, the operator can better observe whether there are foreign objects on the display screen product Y so that the display screen product Y can be wiped and cleaned.

[0057] Please refer to Figure 3 and Figure 4 Specifically, the cage attachment mechanism 13 also 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 may be, but is not limited to, a motor screw mechanism, a linear motor, etc.

[0058] The sliding frame 135 is connected to the output end of the first linear drive module 134, the lifting frame 136 is slidably connected to the sliding frame 135, two attachment lifting cylinders 137 are respectively disposed 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 disposed at the top of the lifting frame 136.

[0059] 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 of the top of the film-tearing lifting cylinder 1331.

[0060] Please refer to Figure 5 The lifting frame 136 includes a sliding plate 1361, a connecting plate 1362, a mounting plate 1363, a mounting block 13C1, a support screw 13C, a pivot screw 13D, a mounting screw, and a screw fine adjuster 13F.

[0061] The sliding frame 135 includes a base plate and side plates perpendicularly connected to the base plate. Figure 4 The reference numeral 135 also refers to the side plate. The sliding plate 1361 is slidably connected to one side of the side plate so that the lifting frame 136 can slide up and down. A pivot screw 13D passes through the middle of the connecting plate 1362 and connects to the sliding plate 1361. A mounting block 13C1 is fixedly installed on the side of the sliding plate 1361 near the connecting plate 1362. Two mounting blocks 13C1 are symmetrically arranged on both sides of the pivot screw 13D. A 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. The connecting plate 1362 is provided with an elongated hole 13E. At least two elongated holes 13E are symmetrically arranged on both sides of the pivot screw 13D. The mounting screw passes through the elongated 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 installed on the mounting plate 1363. The axial direction of the support screw 13C is perpendicular to the axial direction of the attachment roller 132.

[0062] 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 that contacts 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.

[0063] When installing the lifting frame 136, first install the mounting block 13C1 and the support screw 13C. Then, connect the connecting plate 1362 and the sliding plate 1361 using the mounting screw and the pivot screw 13D. At this time, the mounting screw and the pivot screw 13D do not need to be fully tightened, and the support screw 13C supports the connecting plate 1362. Level the connecting plate 1362 by tightening the support screws 13C at both ends. After leveling, tighten the mounting screw and the pivot screw 13D a little. Then, tighten the screw adjuster 13F to perform a finer leveling of the connecting plate 1362. After leveling again, further tighten the mounting screw and the pivot screw 13D completely to ensure high installation accuracy of the attaching roller 132. The attaching roller 132 is very flat relative to the sheet, resulting in good subsequent attaching effect.

[0064] Please refer to Figure 4 In this embodiment, the lifting frame 136 further includes a limiting block 139 and a limiting screw 13A. The limiting block 139 is connected to the sliding plate. The limiting block 139 extends through the side plate to the side away from the sliding plate. An extension plate 13B is provided at the top of the side plate. The limiting screw 13A passes through the extension plate 13B and forms a threaded connection. The limiting block 139 is located on the axial extension line of the limiting screw 13A. The contact between the limiting block 139 and the limiting screw 13A limits the upward stroke of the attachment roller 132, preventing the attachment roller 132 from rising excessively and damaging the display screen product Y.

[0065] 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 the two support rollers 138 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.

[0066] Please refer to Figure 8 In this embodiment, when the sheet X is placed on the mesh, the mesh has exposed areas not covered by the sheet X, and all four sides of the sheet X have exposed areas. The mesh box attachment device for the display screen product also includes adhesive tape 1B, which is attached to some of the exposed areas. This creates a balance between adsorption and leakage, preventing the mesh box body 131 from excessively adsorbing the sheet X and causing the mesh to sag, thus ensuring the flatness of the sheet adsorption and improving the attachment effect.

[0067] Optionally, suction ports communicating with the suction ends of suction mechanisms 18 can be provided on both opposite sides of the mesh box body 131. Each side of the mesh box body 131 can be connected to a corresponding suction mechanism 18, or both sides of the mesh box body 131 can be connected to two suction ends of the same suction mechanism 18. This improves the uniformity of vacuum adsorption of the sheet material within the mesh box body 131. The exposed area without adhesive tape 1B is the leakage area 1B1. The area of ​​the leakage area 1B1 gradually decreases from the direction closest to the suction port to the direction furthest away from the suction port, thus improving the uniformity of sheet material adsorption.

[0068] Please refer to Figure 3 and Figure 6 In this embodiment, the mesh cage attachment device for the display screen product also includes a lifting mechanism 19.

[0069] 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 may be, but is not limited to, a motor screw mechanism, a linear motor, etc.

[0070] The lifting frame 192 is slidably connected to the fixed frame 191 on both sides, and a corresponding slider rail structure 1911 is provided between 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 mounted on the fixed frame 191, and the sliding seat 194 is slidably mounted on the fixed frame 191. The sliding seat 194 is connected to the output end of the second linear drive module 193. An inclined guide rail 196 is provided on the sliding seat 194, and the extension direction of the inclined guide rail 196 forms an inclination 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 the connecting block 195 is slidably connected to the inclined guide rail 196.

[0071] The alignment adjustment platform 1A is connected between the cage attachment mechanism 13 and the lifting frame 192, and the fixed frame 191 is connected to the base 11.

[0072] In this way, the lifting frame 192 can be raised or lowered by moving the sliding seat 194 through the second linear drive module 193. The lifting mechanism 19 has a strong load-bearing capacity and can stably support the alignment adjustment platform 1A and the wire mesh attachment mechanism 13. The lifting drive is more stable and can also improve the sheet attachment effect.

[0073] Please refer to Figure 2 and Figure 7 In this embodiment, the air intake mechanism 18 includes a fan 181, an air intake pipe 182, a switch control valve 183, a pressure relief valve 184, and an exhaust pipe 185.

[0074] 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. The exhaust end of the fan 181 is connected to the external space of the cage body 131 through the exhaust pipe 185.

[0075] The fan 181 requires a relatively long time to start up and reach stable output. In this embodiment, the adsorption of the sheet material by the mesh box body 131 is opened or closed by the switch control valve 183, and the fan 181 does not need to be stopped, thereby improving work efficiency. On the other hand, by setting a pressure relief valve 184, when the switch control valve 183 closes the suction pipe 182, pressure can be released through the pressure relief valve 184. The suction end of the fan 181 will not be completely blocked due to the closure of the switch control valve 183, thus avoiding overheating and damage to the fan 181.

[0076] Among them, the fan 181 can be equipped with a frequency converter, which can control the output of different wind forces of the fan 181.

[0077] In addition, a filter 186 is connected between the fan 181 and the suction pipe 182, which makes it cleaner and can prevent the inside of the fan from getting dirty and damaged.

[0078] Please refer to Figure 2 In this embodiment, the lower positioning camera group 17 includes a first X-axis moving module 171, a first Y-axis moving module 172, a first transverse moving frame 153, a first lower positioning camera 174, and a second lower positioning camera 175.

[0079] The first transverse frame 153 is connected to the output end of the first X-axis moving module 171. The first lower positioning camera 174 and the first Y-axis moving module 172 are mounted on the first transverse frame 153. The second lower positioning camera 175 is connected to the output end of the first Y-axis moving module 172.

[0080] In this way, the first positioning camera 174 can move along the X direction, and the second positioning camera 175 can move along both the X and Y directions, thereby enabling the positioning camera group 17 to take pictures of the four corners of display screen products of different sizes and specifications.

[0081] The upper positioning camera group 15 includes a second X-axis moving module 151, a second Y-axis moving module 152, a second transverse moving frame 173, a first upper positioning camera 154, and a second upper positioning camera 155.

[0082] The second transverse frame 173 is connected to the output end of the second X-axis moving module 151. The first upper positioning camera 154 and the second Y-axis moving module 152 are mounted on the second transverse frame 173. The second upper positioning camera 155 is connected to the output end of the second Y-axis moving module 152.

[0083] 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 and Y directions, thereby enabling the upper positioning camera group 15 to take pictures of the four corners of sheets of different sizes and specifications.

[0084] The working principle of this utility model is as follows: First, the flipping conveyor mechanism 12 is located at the receiving position. The operator places the display screen product Y onto the receiving surface of the flipping conveyor mechanism 12, which is provided with suction holes for adsorbing the display screen product Y. The operator presses the corresponding suction switch of the flipping conveyor mechanism 12, and the flipping conveyor mechanism 12 picks up the display screen product Y. Then, the operator peels off the film from the display screen product Y. After peeling off the film, the ion air bar 14 blows air to clean and destaticate the display screen product Y after peeling off the film.

[0085] In addition, under the illumination of the foreign object lamp 16, the operator can observe and wipe the display product Y.

[0086] The flipping conveyor mechanism 12 flips 180°, and the lower positioning camera group 17 takes pictures of the display screen product Y for positioning. Specifically, under the preset program, the first lower positioning camera 174 moves along the X direction, and the second lower positioning camera 175 moves along both the X and Y directions, so that the lower positioning camera group 17 takes pictures of the four corners of the display screen product.

[0087] According to the size specifications of sheet X, the operator applies adhesive tape 1B to the exposed area of ​​the mesh screen and places sheet X onto the mesh screen of the mesh box body 131. The operator presses the corresponding suction switch on the mesh box body 131, activating the suction mechanism 18 and connecting it to the inner cavity of the mesh box body 131, allowing the mesh box body 131 to hold sheet X. In subsequent applications of the same batch of sheets, it is not necessary to reapply adhesive tape 1B. Furthermore, the operator only needs to control the opening and closing of the switch control valve 183 to turn the mesh box body 131's suction on or off, while the fan 181 continues to operate, improving work efficiency.

[0088] The attaching roller 132 and the film-peeling adsorption mechanism 133 move to the set position, the film-peeling adsorption mechanism 133 rises and adsorbs the sheet X, and then the operator peels the film off the sheet X. After peeling, the ion air bar 14 blows air to clean and destaticate the peeled sheet X.

[0089] The operator presses the attachment switch, and the upper positioning camera group 15 takes pictures 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, so as to achieve the alignment of the sheet X and the display product Y.

[0090] The flipping conveyor 12 moves to the attachment position, the wire mesh attachment mechanism 13 rises a set distance and then stops, the film-peeling adsorption mechanism 133 descends, and the attachment roller 132 rises. The attachment roller 132 moves to roll and attach the sheet X onto the display product Y adsorbed by the flipping conveyor 12. During the process of the attachment roller 132 moving and rolling the sheet X, the moving speed of the attachment roller 132 gradually increases to avoid excessive initial speed of the attachment roller 132 causing sheet misalignment. Specifically, the attachment roller 132 can move at a constant speed for a certain distance and then decelerate once until the sheet is completely attached.

[0091] The adsorption force of the mesh cage body 131 on the sheet X gradually decreases until the adsorption force of the mesh cage body 131 is shut off, to avoid excessive adsorption force of the mesh cage body 131 affecting the adhesion effect during the bonding process. Specifically, the frequency converter can control the fan 181 to output different wind speeds, thereby changing the adsorption force of the mesh cage body 131. The suction mechanism 18 continues to work, and then the adsorption force of the mesh cage body 131 is shut off by controlling the switch control valve 183.

[0092] Sheet X is attached to display product Y. The wire mesh attachment mechanism 13 descends, and the flipping conveyor mechanism 12 moves and flips to reach the receiving position. The operator then removes the attached product.

[0093] Then the process can be repeated to attach the sheet material for the next display product.

[0094] The wire mesh cage attaching equipment in this embodiment is equipped with a film-peeling and adsorption mechanism that adsorbs the sheet material together with the wire mesh cage body. This ensures stable adsorption of the sheet material and prevents misalignment due to the film-peeling operation, thereby improving the subsequent attaching effect and efficiency. Simultaneously, the attaching roller and the film-peeling and adsorption mechanism move together with the lifting frame. When the film-peeling and adsorption mechanism reaches the position for adsorbing the sheet material, the attaching roller moves together to the starting position for rolling and attaching the sheet material, resulting in high work efficiency. Furthermore, the suction mechanism uses a switch control valve to open or close the wire mesh cage body's adsorption of the sheet material, without stopping the fan, thus improving work efficiency.

[0095] In summary, although the present invention has been disclosed above with reference to the above embodiments, the above embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
