[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0028] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0029] In one embodiment of the present invention, see Figures 1-2 An assembly device for a display screen 8 includes an outer frame 1, a support plate 101 inside the outer frame 1, a top box 103 for placing a plurality of outer shells 7 on the top of the outer frame 1, a flip cover 104 hinged to the top of the top box 103, an assembly component 5 corresponding to the outer shell 7 movably disposed above the support plate 101, a flip component 6 connected to the assembly component 5 on the back of the outer frame 1, a glue-spreading component 2 movably disposed on the support plate 101, a positioning component 3 for placing the display screen 8 on the glue-spreading component 2, the positioning component 3 fixing the position of the display screen 8 by cooperating with the glue-spreading component 2, and an injection component 4 movably contacting the positioning component 3 on the support plate 101, the injection component 4 being used to inject glue onto the top of the display screen 8.

[0030] In this embodiment, the display screen 8 is placed on the positioning component 3. The positioning component 3, in conjunction with the glue-spreading component 2, fixes the position of the display screen 8, facilitating the conformal vacuum positioning of the display screen 8 and achieving comprehensive and uniform support for the display screen 8. This avoids the problem of local pressure damage caused by excessive clamping of the surface of the display screen 8 by the existing clamping structure. The glue outlet position of the glue injection component 4 is aligned with the top opening of the display screen 8. The positioning component 3 drives the display screen 8 to rotate synchronously by driving the glue-spreading component 2 to rotate, which facilitates the glue injection component 4 to perform ring-shaped glue dispensing treatment on the top opening of the display screen 8. The assembly component 5 vacuum adsorbs the outer shell 7. The flipping component 6 adsorbs the outer shell 7 located at the bottom of the top box 103 and assembles it at the top opening of the display screen 8 by driving the assembly component 5 to flip up and down. This achieves orderly and automatic assembly of the outer shell 7 and the display screen 8, improves assembly efficiency, and has the advantages of comprehensive and uniform support, effective prevention of pressure damage, ring-shaped uniform glue dispensing, orderly and automatic assembly, reliable structure, convenient operation, and simplicity and practicality.

[0031] Furthermore, the outer frame 1 is symmetrically hinged with movable doors 102 corresponding to the support plate 101. The upper front of the outer frame 1 is provided with a controller 105 that is electrically connected to the electrical equipment inside the equipment. Through the controller 105, it is convenient for the staff to control the start and stop of the electrical equipment inside the equipment, so as to realize the automatic assembly of the outer shell 7.

[0032] It is worth noting that the inner bottom of the top box 103 may also be provided with an annular airbag that contacts the outer edge of the bottom outer shell 7. The annular airbag can effectively support several outer shells 7, which facilitates the orderly and safe adsorption of the bottom outer shell 7.

[0033] In one embodiment of the present invention, see Figures 1-4 The coating assembly 2 includes a turntable 201 rotatably mounted on a support plate 101. A bevel gear ring 202 is provided on the outer bottom edge of the turntable 201. A motor 204 is mounted on the bottom of the support plate 101. The output end of the motor 204 is connected to a bevel gear 203 that meshes with the bevel gear ring 202. A placement platform 205 is provided at the upper center of the turntable 201. Several longitudinal through holes 206 are provided on the placement platform 205. A piston is sealed and slidably mounted within each through hole 206. 207, the bottom of the piston 207 is connected to a lifting rod 208, and the ends of several lifting rods 208 away from the piston 207 are connected by a lifting plate 209. The bottom of the turntable 201 is provided with several uprights 210 that penetrate the lifting plate 209. The uprights 210 are connected to one end of the turntable 201 by a fixing plate 211. A second motor 212 is installed on the fixing plate 211, and the output end of the second motor 212 is connected to a screw 213 that is threadedly connected to the lifting plate 209.

[0034] The positioning component 3 includes a feeding frame 301 disposed above the turntable 201. The feeding frame 301 has a contoured cavity for placing the display screen 8. A sealing ring 303 is provided at the top of the feeding frame 301 to mate with the top of the display screen 8. A connecting sleeve 302, fitted onto the outside of the placement platform 205, is connected to the bottom of the feeding frame 301. The bottom of the connecting sleeve 302 has a bottom ring 304 corresponding to several guide posts 313 disposed on the turntable 201. A sliding plate 306 is symmetrically and slidably disposed on the turntable 201. On the side of the symmetrically disposed sliding plates 306 that are close to each other, an abutment plate 305 is provided that abuts against the bottom ring 304. A rotating part located on the turntable 201 is... A transmission gear 308 is provided between the sliding plates 306. The transmission gear 308 is equipped with a lever 309. Two side racks 307 are distributed on the turntable 201 about the center of the transmission gear 308. The side racks 307 are respectively connected to the corresponding sliding plates 306. The end of the side rack 307 away from the sliding plate 306 meshes with the transmission gear 308. A side groove 310 is provided on the side rack 307. A second sliding plate 312 is slidably arranged in the side groove 310. The end of the second sliding plate 312 away from the side groove 310 is connected to the end of the other side rack 307. A spring 311 is provided in the side groove 310 to grip the side rack 307 and the second sliding plate 312.

[0035] In this embodiment, in the initial state, the symmetrically arranged sliding plates 306 are close to each other, the spring 311 is located to the right of the original length lever 309 and the transmission gear 308, the piston 207 is located at the highest point and corresponds to the internal space of the feeding frame 301. At this time, the piston 207 is located above the placement platform 205, and the lifting plate 209 is located at the highest point.

[0036] Based on the required size of the display screen 8, select a suitable material placement frame 301, and push the lever 309 to rotate to the left around the axis of the transmission gear 308. The lever 309 drives the transmission gear 308 to rotate synchronously through its connection with the transmission gear 308 and the rotational engagement between the transmission gear 308 and the turntable 201. The transmission gear 308 drives the symmetrically arranged slide plates 306 to move away from each other through its meshing with the side rack 307 and the sliding engagement between the slide plate 306 and the turntable 201. The slide plates 306 drive the corresponding abutment plates 305 to move synchronously, thereby increasing the distance between the two placement platforms 205. At the same time, the side rack 307 drives the slide plate 312 connected to its end to move synchronously, thereby decreasing the distance between the two slide plates 312. The spring 311 is stressed and contracts.

[0037] The connecting sleeve 302 is fitted onto the outside of the placement platform 205, so that the bottom ring 304 corresponds to the guide post 313. The lever 309 is released, the spring 311 extends and returns to its original length, so that the distance between the two slide plates 312 increases. The slide plate 312 drives the slide plate 306 to reset by connecting with the side rack 307. The slide plate 306 drives the abutment plate 305 and the bottom ring 304 to abut by moving the abutment plate 305 synchronously, thereby fixing the position of the connecting sleeve 302 and the feeding frame 301. At the same time, the side rack 307 drives the lever 309 to rotate to the right side of the transmission gear 308 by meshing with the transmission gear 308 and connecting the transmission gear 308 and the lever 309, thereby resetting the lever 309.

[0038] The display screen 8 is placed inside the feeding frame 301, with its bottom contacting the top of the piston 207. When the position of the display screen 8 needs to be fixed, the motor 212 drives the screw 213 to rotate forward. The screw 213 moves the lifting plate 209 downward through a threaded connection with the lifting plate 209 and a sliding engagement between the lifting plate 209 and the upright 210. The lifting plate 209 moves the piston 207 downward synchronously through a connection with the lifting rod 208. During the downward movement of the piston 207, the display screen 8 moves downward under its own weight. When the piston 207 moves to the bottom of the top surface of the placement platform 205... Afterwards, the bottom of the display screen 8 contacts the inner bottom of the feeding frame 301. At this time, the display screen 8 stops moving down. As the piston 207 continues to move down, the space enclosed by the bottom of the display screen 8, the inner bottom of the feeding frame 301, the through hole 206, and the piston 207 gradually increases, while the air pressure gradually decreases. Under the action of external atmospheric pressure, the display screen 8 will be tightly fixed inside the feeding frame 301, achieving full and uniform support for the display screen 8. This avoids the problem of excessive clamping of the surface of the display screen 8 by the clamping mechanism, which could cause local pressure damage. This improves the stability and aesthetics of the fixation. At this time, the motor 212 stops working.

[0039] After the outer casing 7 and the display screen 8 are assembled, the second motor 212 drives the first screw 213 to rotate in the opposite direction. The first screw 213 drives the lifting plate 209 to move upward through a threaded connection with the lifting plate 209 and a sliding engagement between the lifting plate 209 and the upright 210. The lifting plate 209 drives the piston 207 to move upward synchronously through a connection with the lifting rod 208. The piston 207 pushes out the assembled display screen 8 by contacting the bottom of the display screen 8, which facilitates the removal of the assembled display screen 8 and the placement of a new display screen 8 to be assembled.

[0040] It is worth noting that when the bottom of the display screen 8 contacts the inner bottom of the feeding frame 301, the inner ring of the sealing ring 303 contacts the outer edge of the bottom of the display screen 8, thereby sealing the annular gap between the top of the feeding frame 301 and the bottom of the display screen 8, avoiding the problem of unstable vacuum positioning caused by subsequent poor sealing, and improving the positioning stability of the display screen 8.

[0041] In one embodiment of the present invention, see Figures 1-5 The glue injection assembly 4 includes a gear platform 408 rotatably mounted on a support plate 101 and a sliding rack 409 slidably mounted on the support plate 101. The sliding rack 409 meshes with the gear platform 408. An electric cylinder 410 connected to the sliding rack 409 is mounted on the support plate 101. A support base 407 is mounted on the gear platform 408. A crossbar 402 is slidably mounted through the support base 407. One end of the crossbar 402 is connected to a screw valve assembly 401. The screw valve assembly 401 is connected to the glue tank through a conduit. The 02 is provided with a retaining ring 405 located between the screw valve assembly 401 and the support base 407. A spring 406 sleeved on the outside of the crossbar 402 is connected between the retaining ring 405 and the support base 407. A vertical rod 403 is installed on the crossbar 402 between the screw valve assembly 401 and the retaining ring 405. An abutment roller 404 is rotatably provided on the vertical rod 403 and moves to abut against the outer wall of the feeding frame 301. A laser sensor 412 is provided on the turntable 201. A laser emitter 411 corresponding to the movement of the laser sensor 412 is provided on the support base 407.

[0042] In this embodiment, in the initial state, the screw valve assembly 401 does not correspond to the top opening of the display screen 8, the abutment roller 404 does not contact the outer wall of the feeding frame 301, the second spring 406 is at its original length, and the electric cylinder 410 is at its original length.

[0043] When it is necessary to apply adhesive to the top opening of the display screen 8, the electric cylinder 410 extends and pushes the sliding rack 409 forward a certain distance. The sliding rack 409 drives the support base 407 to rotate by meshing with the gear table 408 and rotating the gear table 408 and the support plate 101. The support base 407 drives the crossbar 402 to rotate synchronously by slidingly engaging with the crossbar 402. The crossbar 402 drives the abutting roller 404 to rotate synchronously by connecting with the vertical bar 403 and rotating the vertical bar 403 and the abutting roller 404. During the rotation of the abutting roller 404, the side wall of the abutting roller 404 begins to contact the outer wall of the feeding frame 301. As the sliding rack 409 continues to move, the crossbar 402 and the abutting roller 404 continue to rotate.

[0044] Meanwhile, since the position of the feeding frame 301 is fixed at this time, the abutment roller 404 pushes the crossbar 402 and the first retaining ring 405 away from the feeding frame 301 by continuous contact with the side wall of the feeding frame 301 and by the sliding engagement of the crossbar 402 and the support seat 407. The gap between the first retaining ring 405 and the support seat 407 decreases, the second spring 406 is stressed and contracts. When the axis of the crossbar 402 is perpendicular to the direction of movement of the sliding rack 409, the electric cylinder 410 stops extending. At this time, the laser emitter 411 and the laser sensor 412 correspond, and the glue outlet of the screw valve assembly 401 is aligned with the top of the display screen 8. Corresponding to the opening, the laser emitter 411 is powered on and emits a laser. The laser sensor 412 receives the laser and transmits the signal to the controller 105. The controller 105 controls the motor 204 to work. The motor 204 drives the bevel gear 203 to rotate. The bevel gear 203 drives the positioning component 3 and the display screen 8 to rotate synchronously by meshing with the bevel gear ring 202 and by the rotation cooperation of the turntable 201 and the support plate 101. Through the screw valve group 401, the top opening of the display screen 8 can be fully and evenly glued, avoiding the problems of glue overflow or poor adhesion caused by too much or too little glue, thus improving the efficiency of assembly.

[0045] When the laser sensor 412 detects the signal emitted by the laser emitter 411 again, that is, the turntable 201 has rotated one revolution, the top opening of the display screen 8 has been treated with ring-shaped glue, the motor 204 stops working, the electric cylinder 410 retracts and drives the sliding rack 409 to move synchronously. The sliding rack 409 drives the support base 407, the horizontal bar 402, the vertical bar 403 and the abutment roller 404 to rotate synchronously by meshing with the gear table 408 and the rotational cooperation between the gear table 408 and the support plate 101. The spring 406 returns to its original length, realizing the reset of the screw valve group 401.

[0046] It is worth noting that the distance between the abutment roller 404 and the glue outlet of the screw valve assembly 401 is the distance between the outer wall of the feeding frame 301 and the top opening of the display screen 8, which facilitates precise glue dispensing.

[0047] In one embodiment of the present invention, see Figures 1-2 , Figures 6-8 The assembly component 5 includes a mounting plate 501 movably disposed between the support plate 101 and the top box 103.

The end of the screw 605 is connected to a motor 604 disposed on the horizontal plate 603. A threaded plate 609 that slides with the outer wall of the outer frame 1 is threaded to the outer side of the screw 605. The end of the connecting post 601 away from the mounting plate 501 passes through the threaded plate 609 and rotatably engages with it. A transmission gear 608 is connected to the end of the connecting post 601 near the threaded plate 609. A fixed toothed plate 607 is installed in the middle of the part, which is movably meshed with the second transmission gear 608. A guide plate 606 is connected between two horizontal plates 603. A guide rail is provided on the side of the guide plate 606 near the second transmission gear 608. A fixed seat 610 is installed on the threaded plate 609. An abutment rod 612 that contacts the guide rail is slidably provided on the fixed seat 610. A limiting toothed plate 611 that is movably meshed with the second transmission gear 608 is connected to the end of the abutment rod 612 away from the guide plate 606. A retaining ring 613 located between the guide plate 606 and the fixed seat 610 is provided on the abutment rod 612. A spring 614 sleeved on the outside of the abutment rod 612 is connected between the retaining ring 613 and the fixed seat 610.

[0049] In this embodiment, the guide rail includes an upper flat section, an upper slope section, a concave flat section, a lower slope section, and a lower flat section. The guide rail facilitates the flipping of the assembly component 5.

[0050] In the initial state, the threaded plate 609 is at its highest point, the limiting toothed plate 611 meshes with the transmission gear 608, and the suction cup module 503 contacts the outer shell 7 located at the bottom inside the top box 103, and vacuum adsorbs the outer shell 7 located at the bottom inside the top box 103. At this time, the angle of the transmission gear 608 is fixed, and the spring 614 is in a compressed state.

[0051] When the adsorbed outer shell 7 needs to be assembled into the top opening of the already glued display screen 8, the motor 3 604 drives the screw 2 605 to rotate in the forward direction. The screw 2 605 drives the screw plate 609 to move downward through the threaded connection with the threaded plate 609 and the sliding engagement between the threaded plate 609 and the outer wall of the outer frame 1. The threaded plate 609 drives the connecting column 601 to move downward synchronously through the rotational engagement with the connecting column 601 and the meshing of the transmission gear 2 608 and the limiting tooth plate 611. The connecting column 601 drives the adsorbed outer shell 7 to move downward synchronously through the connection with the mounting plate 501. During this process, the abutment rod 612 abuts against the upper flat section, and the spring 3 614 is in a compressed state.

[0052] As the threaded plate 609 continues to move downward, when the abutting rod 612 begins to contact the uphill section, the spring 614 extends and drives the abutting rod 612 to move synchronously by pushing the retaining ring 613 to the left. The abutting rod 612 begins to disengage between the limiting tooth plate 611 and the transmission gear 608 by driving the limiting tooth plate 611 to move synchronously.

[0053] As the threaded plate 609 continues to move downward, when the abutting rod 612 begins to contact the concave section, the spring 614 returns to its original length, and the abutting rod 612 moves to the farthest distance to the left. The abutting rod 612 drives the limiting tooth plate 611 to move synchronously, so that the limiting tooth plate 611 moves to the farthest distance to the left, which can completely disengage the meshing between the limiting tooth plate 611 and the transmission gear 608. At this time, the transmission gear 608 begins to mesh with the fixed tooth plate 607.

[0054] The threaded plate 609 then moves downward. When the abutting rod 612 slides with the concave section, the transmission gear 608 drives the connecting column 601 to rotate downward by 180 degrees through meshing with the fixed toothed plate 607 and the rotational cooperation between the connecting column 601 and the threaded plate 609. The connecting column 601 drives the outer shell 7 to rotate synchronously through connection with the assembly component 5, thereby realizing the flipping of the outer shell 7.

[0055] As the threaded plate 609 continues to move downward, when the abutment rod 612 begins to contact the downhill section, the teeth of the transmission gear 608 leave the lowest tooth of the fixed gear plate 607. The downhill section pushes the abutment rod 612 to the right, and the spring 614 is stressed and retracts. The abutment rod 612 drives the limiting gear plate 611 to the right through its connection with the limiting gear plate 611 and the sliding engagement between the abutment rod 612 and the fixed seat 610. The limiting gear plate 611 begins to mesh with the transmission gear 608.

[0056] As the threaded plate 609 continues to move downward, when the abutment rod 612 contacts the lower flat section, the limiting toothed plate 611 fully meshes with the transmission gear 608, which can fix the angle of the transmission gear 608. The threaded plate 609 moves the outer shell 7 downward by engaging with the connecting column 601 and connecting the connecting column 601 with the assembly component 5, so that the outer shell 7 corresponds to the top opening of the display screen 8, thus realizing the assembly of the outer shell 7 and the display screen 8.

[0057] It is worth noting that the suction cup module 503 uses commercially available suction cup components, including a vacuum generator, solenoid valve, pressure regulating valve, throttle valve, suction cup, vacuum pressure sensor and material detection sensor, which facilitates subsequent maintenance and replacement.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
