DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example 1:

[0041] like Figures 1 to 6 As shown, an LCD loading machine includes a base plate 1, a loading tray 2 is rotatably provided on the left side of the top surface of the base plate 1, and the loading tray 2 is connected to a rotary drive mechanism. The top surface of the loading tray 2 is provided with a plurality of loading grooves 3 evenly distributed along the circumference, and an LCD component 4 is placed inside each loading groove 3. The loading tray 2 is driven to rotate by the rotary drive mechanism, so that the loading grooves 3 on the loading tray 2 can all move to the loading position. The rotary drive mechanism includes a first motor 21 and a belt 22. The first motor 21 is fixedly provided at the left front of the top surface of the base plate 1. The output end of the first motor 21 is vertically upwardly provided and concentrically fixed with a small-diameter pulley 23. A large-diameter pulley 24 is provided at the lower end of the loading tray 2. The large-diameter pulley 24 is coaxially provided with the loading tray 2 and relatively fixed. The small-diameter pulley 23 and the large-diameter pulley 24 are connected by a belt 22. Preferably, the first motor 21 is a stepper motor or a servo motor. A conveyor belt 5 is provided on the right side of the top surface of the bottom plate 1 along the front-to-back direction, and the LCD component 4 is transported to the next workstation via the conveyor belt 5 .

[0042] In order to transfer the LCD component 4 from the loading tray 2 to the conveyor belt 5, a T-shaped plate 11 is fixedly provided in the middle of the top surface of the bottom plate 1, and a first slide rail 12 is fixedly provided on the top of the front of the T-shaped plate 11. A sliding block 13 is provided on the first slide rail 12 for sliding in the horizontal direction, and a second slide rail 14 is provided on the sliding block 13 in the vertical direction. The second slide rail 14 is slidably connected to the sliding block 13, and an air pump 15 is fixedly provided at the bottom end of the second slide rail 14. A pair of suction cups are provided on the bottom surface of the air pump 15; when the bottom surface of the suction cup contacts the top surface of the LCD component 4, the air pump 15 is used to evacuate the suction cup to adsorb the LCD component.

[0043] In order to facilitate the control of the position of the second slide rail 14, a reciprocating shaft is rotatably inserted at the top of the T-shaped plate 11, and a reciprocating swing arm 16 is fixed to the front end of the reciprocating shaft. The outer end of the reciprocating swing arm 16 is hinged to the top end of the second slide rail 14, and the rear end of the reciprocating shaft is connected to the reciprocating drive assembly 6; the reciprocating shaft is driven to rotate by the reciprocating drive assembly 6, and then the reciprocating swing arm 16 is driven to rotate, and the outer end of the reciprocating swing arm 16 drives the upper end of the second slide rail 14 to move synchronously. Under the limiting action of the sliding block 13, the lower end of the second slide rail 14 moves from the upper end of the loading tray 2 to the upper end of the conveyor belt 5 to realize LCD loading.

[0044] In order to facilitate the reciprocating motion of the reciprocating shaft, the reciprocating drive assembly 6 includes a fixed turntable 61, a U-shaped connecting rod 62, a fixed rack 63 and a driven gear 64. A circular through hole is opened on the back of the T-shaped plate 11, and a third motor 65 with an output end facing outward is provided in the circular through hole. The fixed turntable 61 is concentrically fixed to the motor shaft of the third motor 65, and the fixed turntable 61 is driven to rotate by the third motor 65. A limit pin 66 is eccentrically provided on one side of the back of the fixed turntable 61. Two rectangular rings 67 are fixedly provided on the back of the T-shaped plate 11. Two rectangular rings 67 are respectively arranged on the left and right sides of the fixed turntable 61, and the U-shaped connecting rod 62 is slidably set on the two rectangular rings 67, and the U-shaped connecting rod 62 is guided by the two rectangular rings 67; an elliptical ring 68 is fixedly set in the middle of the U-shaped connecting rod 62, and the elliptical ring 68 is arranged in the vertical direction. The outer end of the limit pin 66 is slidably inserted in the elliptical ring 68. When the fixed turntable 61 rotates, the limit pin 66 is driven to rotate synchronously, and then the elliptical ring 68 and the U-shaped connecting rod 62 are driven to reciprocate in the horizontal direction.

[0045] The fixed rack 63 is fixedly arranged at the upper end of the U-shaped connecting rod 62 in the transverse direction, and the driven gear 64 is concentrically fixed to the rear end of the reciprocating shaft and meshes with the fixed rack 63. When the U-shaped connecting rod 62 reciprocates, it drives the fixed rack 63 to reciprocate, and then drives the driven gear 64 and the reciprocating shaft to reciprocate.

[0046] To facilitate the installation of the conveyor belt 5, two pairs of symmetrically distributed L-shaped brackets 51 are fixedly mounted on the right side of the base plate 1. A roller shaft is rotatably mounted between the tops of each pair of L-shaped brackets 51. A concentrically fixed roller 52 is mounted in the middle of each roller shaft. The two rollers 52 are connected by the conveyor belt 5. A second motor 53 is fixedly mounted on one of the L-shaped brackets 51. The end of the motor shaft of the second motor 53 is fixedly connected to the corresponding roller shaft. The second motor 53 drives the rollers 52 to rotate, thus realizing the operation of the conveyor belt 5.

[0047] Specifically, the working principle and operation method of the present invention are as follows:

[0048] Step 1: Place several LCD components 4 in the loading groove 3 of the loading tray 2 and start the third motor 65. The motor shaft of the third motor 65 drives the fixed turntable 61 to rotate synchronously. The limit pin and the elliptical ring 68 form a limit function, driving the U-shaped connecting rod 62 to slide back and forth along a pair of rectangular rings 67. The fixed rack 63 then engages and drives the driven gear 64, the reciprocating shaft, and the reciprocating swing arm 16 to swing back and forth.

[0049] Step 2: When the reciprocating swing arm 16 swings leftward, it drives the sliding block 13 to slide leftward along the first slide rail 12, and simultaneously drives the second slide rail 14 to slide downward along the sliding block 13, and drives the pair of suction cups to press against the corresponding LCD component 4. Then, the air pump 15 is controlled to suck air, and under the action of the air pump 15, the LCD component 4 is adsorbed by the pair of suction cups;

[0050] Step 3: The reciprocating swing arm 16 then swings rightward, driving the sliding block 13 to slide rightward along the first slide rail 12, and simultaneously driving the second slide rail 14 to slide upward and then downward along the sliding block 13, thereby driving the pair of suction cups and the LCD component 4 to fall onto the conveyor belt 5. The air pump 15 is then controlled to deflate, causing the pair of suction cups to release their grip on the LCD component 4.

[0051] Step 4: Start the first motor 21. The motor shaft of the first motor 21 drives the small-diameter pulley 23 to rotate synchronously. The small-diameter pulley 23 drives the large-diameter pulley 24, the fixed shaft, and the loading tray 2 to rotate synchronously via the belt 22, so that the other loading grooves 3 of the loading tray 2 and the LCD device 4 therein rotate a certain angle. Then, the first motor 21 is stopped. In this embodiment, the first motor 21 is a stepping motor.

[0052] Step 5: Start the second motor 53. The motor shaft of the second motor 53 drives the roller, roller 52 and conveyor belt 5 to transport forward, and drives the LCD component 4 to rotate forward to a suitable distance. Then stop the second motor 53 and control the third motor 65 to drive a pair of suction cups to carry out the next LCD component 4 loading process. Example 2:

[0053] like Figures 7 to 10 As shown, this embodiment, based on Example 1, increases the loading capacity of the loading tray 2 by vertically disposing multiple sets of layered structures within the loading groove 3. Each set of layered structures can accommodate an LCD component 4. Sliding holes are provided on both sides of the loading groove 3. Each set of layered structures includes pressing blocks 31 symmetrically positioned on either side of the loading groove 3. These pressing blocks 31 slide within their corresponding sliding holes, with springs 32 positioned between the inner ends of the pressing blocks 31 and the inner bottom surfaces of the sliding holes. Pressing blocks 31 on the same layer support the LCD components 4, while pressing blocks 31 on different layers separate different LCD components 4. The upper and lower outer ends of the pressing blocks 31 are smooth wedge-shaped or curved surfaces 33. This allows the LCD components 4 to move from the upper side of the pressing blocks 31 to the lower side, facilitating material discharge, or from the lower side of the pressing blocks 31 to the upper side, facilitating material removal, when subjected to vertical force.

[0054] To facilitate the gradual upward movement of the LCD component 4 below the loading groove 3, sliding grooves 34 are symmetrically provided on both sides of the loading groove 3. Control blocks 35 are slidably mounted within each of the sliding grooves 34. A wedge-shaped block 36 is fixedly mounted on the side of the control block 3 closest to the loading groove 3. Multiple wedge blocks 36 are vertically arranged, alternating with the pressing blocks 31. A central gear 37 is rotatably mounted on the underside of the loading tray 2. The control blocks 35 on either side of the loading groove 3 are connected to racks 38, which are positioned on either side of the central gear 37 and mesh with it. This rack-and-pinion mechanism enables the control blocks 35 on either side of the loading groove 3 to move synchronously in opposite directions. When the control blocks 35 move synchronously toward each other, the upper end surfaces of the wedge blocks 36 contact the lower side of the corresponding LCD component 4, pushing the LCD component 4 upward until it reaches the upper end of the upper pressing block 31, completing its initial upward movement. Repeat the above operation to transfer the LCD components 4 on the lower layer to the uppermost layer in turn, making it easier for the suction cup to take out the material.

[0055] Each loading groove 3 is provided with a countersunk hole 7 on one side, within which a control rod 71 is disposed. The control rod 71 slides horizontally within the countersunk hole 7. The lower end of the control rod 71 is fixed relative to one of the racks 38, and the upper end of the control rod 71 is fixedly connected to a wedge-shaped control block 72. When the wedge-shaped control block 72 is subjected to force, it drives the control rod 71 to move synchronously, thereby driving the rack 38 to move synchronously, and thus, the control block 35. A return spring 39 is connected to one of the racks 38. When the wedge-shaped control block 72 is free of force, the rack 38 returns to its original position under the action of the return spring 39. The lower end of the second slide rail 14 is fixedly connected to a mounting plate 73. A paddle 74 is hingedly connected to the underside of the mounting plate 73, which engages with the wedge-shaped control block 72. A stopper 75 is fixedly attached to the lower end of the mounting plate 73 to restrict the downward rotation of the paddle 74.

[0056] During the material picking stroke of the suction cup 24, when the second slide rail 14 drives the suction cup 24 to move downward, the lower end of the paddle 74 contacts the upper end of the wedge-shaped control block 72. Since the paddle 74 is hinged to the mounting plate 73, the paddle 74 can freely pass over the wedge-shaped control block 72; when the suction cup completes the adsorption, the second slide rail 14 drives the suction cup 24 to move upward, the paddle 74 pushes the wedge-shaped control block 72 to move away from the loading groove 3, and then drives the rack 38 and the control block 35 to move, thereby realizing the upward movement of the lower LCD component 4.

[0057] The present invention can automatically load the LCD components 4 continuously, greatly improving the production speed and efficiency, completing the loading process more quickly and accurately, saving labor and time costs, and improving the automation level of LCD component 4 loading.

[0058] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
