Technical Field

According to different principles, there are different types of touch screens, such as resistive, capacitive, surface acoustic wave, infrared, and optical imaging. It consists of a protective layer, a touch sensing layer, a display layer, a backlight layer, and a touch control circuit. During assembly, the touch screen needs to be bonded to the substrate of the display screen. The bonding method is glue, usually optical adhesive (OCA), UV glue or other glue.

[0003] The process of bonding the substrate and the touch screen requires that glue be evenly applied to the substrate, and then the touch screen and the substrate are bonded, the edges are aligned, and then they are placed in a vacuum chamber for negative pressure treatment to remove bubbles from the bonding surface. The above process adopts distributed operation. The processes of gluing, edge alignment and de-bubbling require the cooperation of a glue coating machine, an alignment mechanism, a negative pressure machine and a transfer equipment. A lot of equipment is required. During transfer, a certain amount of material needs to be accumulated before transfer.

[0031] Combined with Figure 3 , Attachment Figure 4 , Attachment Figure 5 and attached Figure 6 As shown, the base 2 includes a material trough 21 for placing a substrate, a sealing strip 1 211 and a sealing strip 212 are respectively provided at the bottom and the outer side of the material trough 21, a sealing groove 31 matched with the sealing strip 212 is provided on the sealing cover 3, an exhaust port 213 connected to the material trough 21 is provided on one side of the base 2, a motor 23 is provided at the four corners of the bottom of the base 2, a threaded rod 231 is provided at the output end of the motor 23, the threaded rod 231 passes through the through hole on the base 2, a threaded hole matched with the threaded rod 231 is provided on the sealing cover 3, the top of the sealing cover 3 is movably connected with the double-position support arm 53, the top of the threaded rod 231 is provided with a positioning head 232, the bottom of the base 2 is provided with a cylinder 24, the output end of the cylinder 24 A lifting plate 241 is provided, which passes through the through hole at the bottom of the material trough 21 and is located in the material trough 21. The four sides of the material trough 21 between the sealing strip 1 211 and the sealing strip 212 are provided with sliding grooves 214. A straightening push plate 221 is slidably provided in the sliding groove 214. A magnetic column 222 is provided at the rear end of the straightening push plate 221. An electromagnetic generator 22 is provided at the position of the magnetic column 222 on the outside of the base 2. A plurality of slot columns 32 are provided at the bottom of the inner side of the sealing cover 3. A pressure plate 1 33 is slidably provided at the bottom of the middle slot column 32. A pressure plate 2 34 is slidably provided at the bottom of the side slot column 32. The pressure plates 1 33 and 34 are connected to the slot column 32 through a spring 1 35. The bottom of the pressure plate 1 33 is lower than the bottom of the pressure plate 2 34.

[0032] Working principle of the base 2 and the sealing cover 3: the substrate is moved from the conveyor belt to the top of the material trough 21 through the substrate clamping mechanism 6, and then the cylinder 24 pushes the lifting plate 241 to rise, the substrate clamping mechanism 6 places the substrate on the lifting plate 241, and the cylinder 24 drives the lifting plate 241 to reset. Before the substrate is placed at the bottom of the material trough 21, the electromagnetic generator 22 is energized to generate magnetism, and the magnetic force drives the magnetic column 222 to move, driving the alignment push plate 221 to slide in the slide groove 214. Under the joint push of the alignment push plates 221 at multiple positions, the substrate is aligned with the material trough 21, and then the lifting plate 241 falls into the groove, and the substrate is placed in the material trough 21, and then the surface of the substrate is evenly coated by the gluing mechanism 8. The glue is evenly applied, and then the screen board feeding mechanism 7 transfers the touch screen to the substrate. The feeding process of the touch screen is the same as that of the substrate, and both require the lifting plate 241 to rise and the squaring push plate 221 to push, so that the edge of the touch screen is aligned with the substrate and falls into the material slot 21. Then the sealing cover 3 moves to the top of the material slot 21. During the process of the sealing cover 3 descending with the double-position support arm 53, the positioning head 232 is inserted into the threaded hole on the side of the sealing cover 3. Since the top of the sealing cover 3 is movably connected with the double-position support arm 53, the sealing cover 3 has a certain lifting and rotating movement. The motor 23 drives the threaded rod 231 to rotate, so that the threaded rod 231 is screwed into the threaded hole on the side of the sealing cover 3, so that the sealing cover 3 is tightly fitted with the base 2; When the sealing cover 3 is tightly attached to the base 2, the pressing plate 1 33 first contacts the center of the touch screen, and then the pressing plate 2 34 contacts the side of the touch screen. Pressure is applied to the touch screen by the pressing plates 1 33 and 2 34 in turn, so that larger bubbles on the bonding surface of the touch screen and the substrate are discharged from the center to the outside. After the sealing cover 3 is tightly attached to the base 2, the sealing strip 1 211 is attached to the substrate, and the sealing strip 212 is attached to the sealing groove 31, so that the touch screen and the edge of the substrate are in a closed space. The negative pressure device forms a negative pressure in the cavity between the sealing strip 1 211 and the sealing strip 212 through the exhaust port 213, and all bubbles on the bonding surface of the touch screen and the substrate are discharged. When using UV glue, the material trough 21 and the lifting plate 241 are made of transparent material plates, and an ultraviolet generator is added under the material trough 21 to cure the UV glue.

[0033] Combined with Figure 1 , Attachment Figure 2 , Attachment Figure 7 and attached Figure 8As shown, the driving mechanism 4 includes a motor 2 41, a driving shaft 42 and a transmission swivel 46, a gear 1 411 is provided at the output end of the motor 2 41, a gear 2 421 meshing with the gear 1 411 is provided on the driving shaft 42, a worm wheel 44 and a gear 3 45 coaxially connected and rotatable are provided in the base 1, worms 43 meshing with the worm wheel 44 are provided at both ends of the driving shaft 42, and the tooth profiles of the two worms 43 are in opposite directions, a gear ring 461 meshing with the gear 3 45 is provided on the outer side of the transmission swivel 46, and a spline groove 462 is provided on the inner side of the transmission swivel 46, and the transposition structure 5 includes a cylinder 2 51 and a spline shaft 52, a turntable 511 is provided at the output end of the cylinder 2 51, the turntable 511 is rotatably matched with the bottom of the spline shaft 52, the spline shaft 52 is slidably matched with the spline groove 462, and the tops of the two spline shafts 52 are respectively connected to the double-position support arm 53 and the three-position support arm 54.

[0034] The working principle of the driving mechanism 4 and the transposition structure 5 is as follows: the motor 2 41 drives the gear 1 411 to rotate, and the gear 1 411 is meshed with the gear 2 421 to make the driving shaft 42 rotate, and the gear 3 45 is rotated through the meshing transmission of the worm wheel 44 and the worm 43, and the transmission ring 46 is rotated in the base 1 through the meshing transmission of the gear 3 45 and the gear ring 461, and the spline shaft 52 is driven to rotate through the spline groove 462, thereby driving the double-position support arm 53 and the three-position support arm 54 to rotate. Since the tooth profiles of the two worms 43 and the worm wheel 44 are in opposite directions, the two worms 43 and the worm wheel 44 are meshed with each other, so that ... The worm gears 44 rotate in opposite directions, so that the double-position support arm 53 and the three-position support arm 54 rotate synchronously and in opposite directions. At each rotation, the double-position support arm 53 and the three-position support arm 54 rotate by 60°, so that the substrate clamping mechanism 6 (feeding), the gluing mechanism 8, the screen plate feeding mechanism 7, the sealing cover 3 and the substrate clamping mechanism 6 (discharging) are moved to the position above the base 2 in sequence, and the spline shaft 52 is driven by the cylinder 2 51 to move up and down in the spline groove 462, so that the double-position support arm 53 and the three-position support arm 54 respectively drive the functional mechanisms at the ends to rise and fall to reach their respective working positions.

[0035] Combined with Figure 2 , Attachment Fig. 9 and attached Fig.10 As shown, the substrate clamping mechanism 6 also includes a cylinder three 61 and a fixed platform 62. The cylinder three 61 and the fixed platform 62 are both fixed at the end of the three-position support arm 54.

Transverse platforms 632 are arranged on both sides of the transverse platform. A transverse groove 621 slidably matched with the transverse platform 632 is arranged on the inner side of the fixed platform 62. A clamping sheet 633 is arranged on the outer side of the transverse platform 631, and a soft pad 634 is arranged on the inner side of the clamping sheet 633.

[0036] Working principle of substrate clamping mechanism 6: After substrate clamping mechanism 6 moves to the working position of conveyor belt, three-position support arm 54 drives substrate clamping mechanism 6 to descend, and then cylinder three 61 drives lifting platform 611 to rise, and is hinged with lifting platform 611 and transverse moving platform 631 of clamping claw 63 through two ends of transmission rod 64, and transverse moving platform 632 and transverse groove 621 slide and cooperate, so that transverse moving platform 631 moves transversely toward the axis of lifting platform 611, so that multiple clamping pieces 633 are synchronously close to the edge of substrate, and the substrate is clamped by soft pad 634, and the substrate is dropped onto lifting plate 241 through rotation and lifting of three-position support arm 54, and after the substrate and touch screen are bonded and cured, another substrate clamping mechanism 6 is used to clamp the substrate and touch screen on lifting plate 241 and transfer them to conveyor belt.

[0038] Working principle of screen feeding mechanism 7: after screen feeding mechanism 7 moves to the working position of conveyor belt, three-position support arm 54 drives screen feeding mechanism 7 to descend, after suction cup 74 falls on touch screen, external air pump forms negative pressure on suction cup 74, so that suction cup 74 adsorbs touch screen, then screen feeding mechanism 7 moves to above material slot 21 driven by three-position support arm 54, then screen feeding mechanism 7 descends with three-position support arm 54, stops at a certain distance from substrate, then touch screen is pre-aligned by aligning push plate 221, then aligning push plate 221 is reset, then touch screen falls on substrate, after suction cup 74 is separated from touch screen, screen feeding mechanism 7 rises, aligning push plate 221 pushes touch screen again, so that touch screen is aligned with edge of substrate; The swinging member 72 enables the floating plate 73 to rotate, rise and fall at multiple angles and move, so as to cooperate with the aligning push plate 221 to align the touch screen with the edge of the substrate. Fig.12The four swinging members 72 are evenly distributed between the top plate 71 and the floating plate 73. The upper ball table 721 and the lower ball table 724 cooperate with the ball groove column 1 711 and the ball groove column 2 731 respectively, so that the floating plate 73 has a certain lateral rotation space. The pipe column 722 and the sliding column 723 slide together, so that the floating plate 73 has a certain lifting space, and at the same time, the floating plate 73 can move and rotate at multiple angles, so that when the push plate 221 pushes the touch screen, the touch screen will not be damaged. The spring 2 725 mounted on the pipe column 722 prevents the touch screen from being crushed when the screen feeding mechanism 7 moves downward excessively.

Under the drive of the driving mechanism 4, the double-position support arm 53 and the three-position support arm 54 of the transposition structure 5 are synchronously rotated in opposite directions, each time rotating 60°, so that the substrate clamping mechanism 6 (feeding), the gluing mechanism 8, the screen plate feeding mechanism 7, the sealing cover 3 and the substrate clamping mechanism 6 (discharging) are sequentially moved to the position above the base 2, the substrate clamping mechanism 6 sends the substrate to the base 2, and the glue is evenly applied to the upper surface of the substrate through the gluing mechanism 8. Then the screen plate feeding mechanism 7 puts the touch screen on the substrate, and then the sealing cover 3 is pressed onto the base 2 to form a negative pressure cavity, and then another substrate clamping mechanism 6 puts the bonded touch screen and substrate back on the conveyor belt.
