Users can use a stylus or digital pen to operate on the touch screen, replacing the traditional keyboard or mouse. During the production process of tablet computers, the touch screen needs to be bonded to the tablet computer body. Currently, in the process of screen bonding, most factories use traditional manual assembly to bond, which easily increases the labor burden of workers and reduces the bonding effect between the screen and the shell. There are also single automated assembly equipment for bonding, but it still requires manual assistance to complete the operation, and it cannot be combined with other production equipment into an automated production line, which easily reduces the production efficiency of tablet computers.

[0015] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0016] A tablet screen automated assembly device comprises an assembly box 1, a symmetrical drive box 11 detachably connected to the outside of the assembly box 1, and four symmetrical sets of rotating plates 12 rotatably connected to the inside of the assembly box 1. A fixed plate 13 is fixedly connected between the rotating plates 12 on the same side on the inside of the assembly box 1. Four symmetrical sets of rotating wheels 14 are rotatably connected to the inside of the rotating plates 12 on the same side at the corners of the assembly box 1. The rotating wheels 14 are engaged with the drive box 11. A No. 1 transmission medium 15 is sleeved on the outer circumference of the rotating wheels 14 on the same side. A receiving plate 2 is detachably connected to the surface of the No. 1 transmission medium 15 on the top of the assembly box 1. The rotating plates 12 on the same side are fixedly connected to the inside of the assembly box 1. A rotating mechanism 3 for rotating the receiving plate 2 inside the assembly box 1 is provided on the opposite side, and a bonding device 4 for pressing, defoaming and curing the shell and the screen is provided on the rear side of the assembly box 1. An integration mechanism 5 for conveying the shell and the screen to the inside of the bonding device 4 is provided below the receiving plate 2 at the bottom of the assembly box 1. A reversing mechanism 9 for exchanging the position of the workpiece on the receiving plate 2 and the workpiece on the integration mechanism is provided between the receiving plate 2 and the integration mechanism 5 on the front side of the assembly box 1. A shell conveying mechanism 6 for conveying the shell to the integration mechanism 5 is provided on the left side of the reversing mechanism 9 on the front side of the assembly box 1.

[0017] like Figure 1 and Figure 3-Figure 4As shown, two groups of rotating plates 12 are symmetrically installed on the left and right side walls of the assembled box body 1. There are four groups of rotating plates 12 inside the assembled box body 1, of which the same number of fixed plates 13 and rotating plates 12 are set. Two groups of fixed plates 13 are symmetrically fixedly connected to the left and right side walls of the assembled box body 1. The fixed plates 13 are located on the opposite surfaces between the rotating plates 12 on the same side. The bottoms of the ends of the opposite surfaces of the rotating plates 12 are in contact with the upper surfaces of the fixed plates 13. When stationary, the fixed plates 13 support the rotating plates 12. It should be noted that the rotating mechanism 3 does not contact the fixed plates 13 when it is in operation; the end of the rotating plate 12 away from the fixed plate 13 is rotatably connected to the side wall of the assembled box body 1; like Figure 3 As shown, four groups of rotating wheels 14 are rotatably connected to the four corners of the right side wall of the assembly box 1, and four groups of rotating wheels 14 are also provided on the left side wall of the assembly box 1. The rotating rods of the two groups of rotating wheels 14 on the top of the assembly box 1 pass through the rotating plate 12 and extend to the inside of the drive box 11. The motor in the drive box 11 can drive the rotating wheels 14 to rotate through the rotating rods. The two groups of rotating wheels 14 at the bottom of the assembly box 1 are equivalent to auxiliary wheels. The first transmission medium 15 is sleeved on the outer circumference of the rotating wheel 14 on the same side. The first transmission medium 15 can be a belt or a chain to assist the first transmission medium 15 to rotate inside the assembly box 1; like Figure 3 As shown, the receiving plate 2 is detachably connected to the surface of the No. 1 transmission medium 15. When the No. 1 transmission medium 15 rotates repeatedly, the receiving plate 2 will move back and forth on the top of the assembly box 1. It should be noted that the receiving plate 2 is provided with a placement groove on the top and bottom axis centers, and a plurality of air holes are provided on the bottom surface of the placement groove. The interior of the receiving plate 2 is provided with cavities on both sides. Vacuum pumps are installed on the rear of the top surface and the front of the bottom surface of the receiving plate 2. The air pipes of the vacuum pumps are connected to the corresponding cavities. The vacuum pumps can be divided into two parts to perform air suction by the vacuum pump to turn the receiving plate 2 into a vacuum adsorption plate, thereby reducing the shaking of the screen on the surface of the receiving plate 2. like Figure 3-Figure 5 As shown, the rotating mechanism 3 includes a turntable 31 rotatably connected to the side wall of the assembly box 1. Two groups of turntables 31 are provided. The two groups of turntables 31 are rotatably connected to the left side wall and the right side wall of the assembly box 1 respectively, and the turntables 31 are located between the rotating plates 12 on the same side. The rotating rod of the turntable 31 passes through the assembly box 1 and extends to the inside of the drive box 11. The drive box 11 has a corresponding motor inside to drive the turntable 31 to rotate. like Figure 4-Figure 5The cam 32 is connected to the cam 33 of the second gear 35 and the cam 33 of the third gear 36. like Figure 3-Figure 5 As shown, initially, the turntable 31 drives the mounting plate 32 to rotate toward the rear side of the assembly box body 1, and the second wheel 35 on the rear side of the mounting plate 32 is low to the bottom groove of the rotating plate 12, so that the rear rotating plate 12 rotates counterclockwise around the rear end until the mounting plate 32 rotates 90 degrees, so that the opening between the two sets of second wheels 35 is opposite to the opening on the rear side of the rotating plate 12 on the front side of the assembly box body 1, so that the first transmission medium 15 on the outer circumferential surface of the second wheel 35 on the top front side of the mounting plate 32 is changed from bent to horizontal; when the receiving plate 2 enters between the two sets of second wheels 35 from the inside of the rotating plate 12 on the front side of the assembly box body 1, and the middle top of the support frame 33 is against the rear side of the receiving plate 2, then the turntable 31 rotates 90 degrees clockwise, and the turntable 31 drives the support frame 33 from horizontal to vertical. At this time, the receiving plate 2 is still between the two sets of second wheels 35 , then the turntable 31 rotates clockwise by 90° again, so that the No. 1 transmission medium 15 on the outer circumferential surface of the No. 2 wheel 35 on the rear side of the top of the mounting plate 32 changes from being bent to being horizontal. At this time, the opening between the two sets of No. 2 wheels 35 is opposite to the opening on the front side of the rotating plate 12 on the rear side of the assembly box 1. The receiving plate 2 enters the interior of the rotating plate 12 on the rear side of the assembly box 1 from between the two sets of No. 2 wheels 35. At this time, the receiving plate 2 is inside the rotating plate 12 on the rear side of the assembly box 1. The turntable 31 drives the support frame 33 to rotate 90° counterclockwise. At this time, the support frame 33 returns to being vertical and the receiving plate 2 is no longer between the two sets of No. 2 wheels 35. At the same time, driven by the No. 1 transmission medium 15, the receiving plate 2 on the rear side can move from the rotating plate 12 on the rear side to the rotating plate 12 on the front side, so that both the front and back sides of the receiving plate 2 are in contact with the integration mechanism 5. like Figure 3 and Figure 7As shown, the integration mechanism 5 includes a pulley 51 rotatably connected to the outside of the rotating wheel 14. The rotating wheel 14 here refers to the rotating wheel 14 located at the bottom of the assembly box 1. One end of the pulley 51 rotating rod is sleeved on the outside of the rotating rod of the rotating wheel 14, so that the pulley 51 is rotatably connected to the rotating wheel 14. The other end of the pulley 51 rotating rod on the front side of the assembly box 1 is rotatably connected to the side wall of the assembly box 1. The pulley 51 rotating rod located on the rear side of the assembly box 1 passes through the assembly box 1 and extends to the outside. The other end of the pulley 51 rotating rod is detachably connected to a corresponding motor. Therefore, the pulley 51 and the rotating wheel 14 have different driving sources and rotate asynchronously, and can be divided into two parts. like Figure 7-Figure 8 As shown, a second transmission medium 52 is sleeved on the outer circumference of the pulley 51 between the pulleys 51 on the same side. The second transmission medium can also be a belt or a chain. The left and right sides of the support plate 53 are detachably connected to the second transmission medium 52. A movable plate 54 is slidably connected to the middle of the support plate 53. Two symmetrical groups of telescopic cylinders 55 are installed on the bottom surface of the support plate 53. The first part of the piston rod of the telescopic cylinder 55 is detachably connected to the bottom surface of the movable plate 54. If the telescopic cylinder 55 is started, the telescopic cylinder 55 can push the movable plate 54 to move inside the middle of the support plate 53; when the second transmission medium 52 is detachably connected to the left and right sides of the support plate 53, the movable plate 54 is detachably connected to the middle of the support plate 53. When the dynamic medium 52 moves to the vicinity of the feed port of the bonding device 4 through the support plate 53, a shell and a screen are placed on the upper surface of the movable plate 54, and the telescopic cylinder 55 can push the movable plate 54 to move to the inside of the bonding device 4. The bonding device 4 is located on the rear side of the assembly box 1, and the rear surface of the assembly box 1 is provided with an operation screen and operation buttons for controlling the bonding device 4. The bonding device 4 is the same as the existing bonding technology, and can be vacuum defoamed, pre-pressed and UV cured; after the bonding is completed, it can be returned to the bottom of the receiving plate 2 through the movable plate 54 under the drive of the second transmission medium.

[0018] The shell is transported to the upper surface of the movable plate 54 by the shell conveying mechanism 6, and the screen on the back of the receiving plate 2 is transferred to the upper surface of the movable plate 54 by the reversing mechanism 9, so that the screen covers the upper surface of the shell; When the movable plate 54 moves toward the laminating device 4, the rotating plate 12 on the rear side of the assembly box 1 has rotated 90° clockwise. When the screen is processed and cut, the movable plate 54 moves toward the reversing mechanism 9. At this time, the receiving plate 2 has been turned over and the rotating mechanism 3 is in a vertical position. Therefore, the movable plate 54 moves and does not contact the turned-over receiving plate 2. like Figure 1 、 Figure 3 and Figure 7As shown, the shell conveying mechanism 6 includes a feed port 61 opened on the surface of the assembly box 1, and the feed port 61 is located on the left side of the support plate 53. The outer surface of the bracket 62 is fixedly connected to the inner side of the feed port 61. There are two symmetrical conveyor belt devices 63. The conveyor belt device 63 is composed of wheels and belts, and a protrusion is provided on the outer surface of the belt. The protrusion can be used to fix the position of the shell. The wheel is equipped with a corresponding motor, which can drive the shell to move toward the feed port 61 by rotating the belt; a positioning mechanism 7 is provided inside the bracket 62 and between the conveyor belt devices 63. The surface of the support plate 53 is A movable groove 64 is provided on the right side of the positioning mechanism 7. The right end of the movable groove 64 passes through the support plate 53 and extends to the middle of the movable plate 54. The entire movable groove 64 is not located on the left and right axis of the upper surface of the movable plate 54. The entire movable groove 64 is close to the front side of the upper surface of the movable plate 54, so that the movable plate portion with the screen and the shell placed thereon can be extended into the laminating device to facilitate the laminating process of the screen and the shell. When the shell moves to the top of the positioning mechanism 7, the positioning mechanism 7 can drive the shell to move along the movable groove 64 to the upper surface of the movable plate 54, so that the shell is in contact with the screen on the reverse side of the receiving plate 2; like Figure 3 and Figure 9 As shown, the positioning mechanism 7 includes a No. 1 plate 71, the left and right ends of which are fixedly connected to the left side wall of the bracket 62 and the right side wall of the assembly box 1 respectively, and a screw rod 74 is fixedly connected to the top surface of the No. 1 plate 71 through a plurality of mounting brackets 73. A column 75 is slidably connected to the surface of the screw rod 74, wherein the left side of the screw rod 74 is detachably connected to a corresponding motor, and a nut is provided at the connection between the column 75 and the screw rod 74; a No. 2 plate 76 is slidably connected to the left side of the column 75, and a positioning plate 77 is detachably connected to the top of the No. 2 plate 76. It should be noted that the positioning plate 77 is the same as the receiving plate 2, and the positioning plate 77 is also provided as an adsorption plate; like Figure 9As shown, the bottom of the second plate 76 is fixedly connected to the first rod 78, the rear surface of the first plate 71 is provided with a return groove 72, the front end of the first rod 78 is fixedly connected to the second rod 79, the tail of the second rod 79 is provided with a convex rod, the front end of the convex rod is set to a rectangle, the rectangular part is made of magnetic material, and at the same time, magnetic pieces 84 are respectively provided at the corners of the bottom of the return groove 72, wherein the magnetic piece 84 at the right corner of the bottom of the return groove 72 is opposite to the magnetic surface of the rectangular part of the convex rod, and the magnetic piece 84 at the left corner of the bottom of the return groove 72 is the same as the magnetic surface of the rectangular part of the convex rod; the screw rod 74 drives the column 75 toward the movable plate 5 4 movement, the column 75 drives the second rod 79 to move inside the return groove 72 through the first rod 78. When the front end of the protruding rod is located at the left corner of the return groove 72, the magnetic piece 84 and the opposite surface of the protruding rod have the same magnetic properties, so the second rod 79 drives the second plate 76 to slide on the left side of the column 75 through the first rod 78, and under the traction of the screw rod 74, the tail of the second rod 79 slides on the top of the return groove 72. Conversely, when the front end of the protruding rod is located at the right corner of the return groove 72, the magnetic piece 84 and the opposite surface of the protruding rod have opposite magnetic properties, and the tail of the second rod 79 slides on the bottom of the return groove 72, thereby realizing the up and down movement of the positioning plate 77; During operation, the shell is moved to the top of the positioning plate 77 under the push of the conveyor belt device 63. At this time, the tail of the No. 2 rod 79 has not reached the left corner of the return groove 72. The motor can rotate forward and reverse. First, reverse the screw rod 74 to move the tail of the No. 2 rod 79 to the left corner, so that the positioning plate 77 lifts the shell and the shell is separated from the conveyor belt device 63. Wait until the tail of the No. 2 rod 79 moves to the right corner of the return groove 72, the positioning plate 77 is reset to the initial height and the shell is placed on the upper surface of the movable plate 54, thereby completing the operation of transporting the shell to the movable plate 54.

[0019] A rotatable connecting ball can also be attached to the front end surface of the convex rod to reduce the friction between the front end surface of the convex rod and the surface of the return groove 72 through the ball, which is beneficial to the smooth movement of the convex rod in the return groove 72.

[0020] like Figure 7 As shown, due to the provision of the movable groove 64, the No. 2 transmission medium 52 on the left side of the assembly box 1 has a break. The two breaks of the No. 2 transmission medium 52 are respectively connected to the front and rear sides of the support plate 53 on the left side of the assembly box 1 through the fixing member 8, so as to ensure the normal operation of the support plate 53. At the same time, the upper surface of the fixing member 8 is fixedly connected to the limit rod 81, and the top of the limit rod 81 is fixedly connected to the guide rod 82 inside the assembly box 1. The front and rear ends of the guide rod 82 are respectively fixedly connected to the front and rear side walls of the assembly box 1. The bottom surface of the guide rod 82 is provided with a limit groove 83, and the top of the limit rod 81 is slidably connected inside the limit groove 83 to support the movement of the No. 2 transmission medium 52 and is conducive to improving the stability of the movement of the support plate 53. like Figure 5-Figure 6As shown, the reversing mechanism 9 includes a support column 91 rotatably connected to the inner wall of the front side of the assembly box 1, and a rotating motor 92 is detachably connected to the front surface of the support column 91. The rotating motor 92 can drive the support column 91 to rotate on the inner wall of the front side of the assembly box 1, and a frame 93 is detachably connected to the rear surface of the support column 91. The rear surface of the frame 93 is slidably connected to two symmetrical groups of inclined blocks 94. The inclined blocks 94 are triangular in shape, and an L-shaped plate 95 is fixedly connected to the rear surface of the inclined blocks 94. The L-shaped plate 95 is connected to the reversing plate 97. The reversing plate 97 is configured in the same manner as the positioning plate 77 and the receiving plate 2. The reversing plate 97 is configured as an adsorption plate, and the vacuum air pumps of the two groups of reversing plates 97 can be divided into two groups. like Figure 5 As shown, the trapezoidal block 98 is slidably connected between the inclined blocks 94, and the inclined surface of the inclined block 94 is opposite to the inclined surface of the trapezoidal block 98, wherein the inclined surface of the inclined block 94 is provided with a groove, and the inclined surface of the trapezoidal block 98 is fixedly connected with a protrusion, which fits into the groove. The front surface of the trapezoidal block 98 is detachably connected to the piston rod of the movable cylinder 99, and the movable cylinder 99 is fixedly connected to the inside of the frame 93. When the piston of the movable cylinder 99 moves toward the rear side of the assembly box 1, the trapezoidal block 98 pushes the two groups of inclined blocks 94 to move upward and downward respectively, so that the two groups of reversing plates 97 are respectively in contact with the receiving plate 2 and the movable plate 54. Conversely, when the piston of the movable cylinder 99 moves toward the front side of the assembly box 1, the trapezoidal block 98 drives the two groups of inclined blocks 94 toward the axis direction of the trapezoidal block 98, so that the two groups of reversing plates 97 are respectively separated from the receiving plate 2 and the movable plate 54. During operation, the trapezoidal block 98 drives the two groups of reversing plates 97 to contact the receiving plate 2 and the movable plate 54 respectively through the inclined block 94. The vacuum pumps on the receiving plate 2 and the movable plate 54 are turned off, and the vacuum pump on the reversing plate 97 is turned on, so that the top reversing plate 97 adsorbs the screen. The screen and the shell have been bonded together and are called finished parts. The bottom reversing plate 97 adsorbs the finished parts. Then the trapezoidal block 98 drives the two groups of reversing plates 97 to separate from the receiving plate and the movable plate 54 respectively, and starts the rotating motor 92. The rotating motor 92 drives the frame 93 to rotate through the support column 91, so that the reversing plate 97 originally at the top moves to the bottom. Similarly, the reversing plate 97 originally at the bottom moves to the top. The finished part is flipped to the upper surface of the receiving plate 2 through the rotating mechanism 3 and transported to other equipment through the existing robotic arm. The screen moves to the top of the movable plate 54. At this time, a new shell has been placed on the upper surface of the movable plate 54, and the next screen and shell bonding operation is carried out.

[0021] It should be noted that the present invention is an automated assembly device for tablet computer screens, such as Figures 1-9 As shown, when in use, the screen is first placed on the upper surface of the receiving plate 2 by the existing mechanical arm. The rotating mechanism 3 rotates the receiving plate 2 180 degrees and returns it to the initial position under the push of the first transmission medium 15. At this time, the screen is located on the lower surface of the receiving plate 2, and there is no screen on the upper surface of the receiving plate 2. Then the whole assembly equipment starts to operate, the existing robot arm places the new screen on the upper surface of the receiving plate 2, and at the same time the shell transport device transports the shell to the upper surface of the movable plate 54 through the positioning mechanism 7, and the reversing device moves the screen on the lower surface to the movable plate 54. In the process of the receiving plate 2 moving from the rotating plate 12 on the front side of the assembly box 1 to between the two sets of second wheels 35, the support plate 53 drives the movable plate 54 to move to the bonding device 4, and pushes the movable plate 54 into the bonding device 4. After the movable plate 54 is pushed out of the bonding device 4, the receiving plate 2 is located above the movable plate 54, and the rotating machine The structure 3 is in a vertical state, and then the receiving plate 2 and the movable plate 54 move to the top and bottom of the reversing mechanism 9 together. At this time, the new screen is located on the lower surface of the receiving plate 2. A reversing plate 97 of the reversing mechanism 9 moves the new screen to the top of the movable plate 54, and the other reversing plate 97 moves the finished part to the bottom of the receiving plate 2. When the new shell moves to the movable plate 54, the new screen is placed on the movable plate 54, and the finished part is flipped to the upper surface of the receiving plate 2 by the rotating mechanism 3, and transported to other equipment by the existing robotic arm, so that multiple screens and multiple shells are assembled in a cycle.
