[0039] The present invention provides an automatic veneer pasting device for a writing board, including a machine table 10, where the machine table 10 is used to carry each processing mechanism; a station moving mechanism 20 disposed at the center of the machine table, including a rotatable turntable 21, and a plurality of processing stations are provided on the turntable 21. The turntable 21 is preferably disposed in the middle of the machine table 10; a veneer feeding mechanism 30, an adhesive mechanism 40, a dust-proof paper tearing mechanism 50, and an assembly mechanism 60 are disposed around the turntable 21. The veneer feeding mechanism 30 includes a liftable carrier plate 31, and the carrier plate 31 is used to lift and feed the veneer; the adhesive mechanism 40 is used to cut off the tape and paste it onto the dust-proof paper of the veneer, and a part of the tape is left after pasting for clamping in subsequent steps; the dust-proof paper tearing mechanism 50 is used to pull the tape and tear off the dust-proof paper on the veneer through the tape. The dust-proof paper tearing mechanism 50 includes a movable chuck 51, and the chuck 51 is used to clamp the tape; the assembly mechanism 60 is located above the processing station and is used to bond the veneer to the writing board; wherein the veneer feeding mechanism 30, the adhesive mechanism 40, the dust-proof paper tearing mechanism 50, and the assembly mechanism 60 are sequentially disposed on the circumferential side of the turntable and are distributed around the circumference of the turntable. On one side of the machine table 10, a writing board transfer mechanism 70 for transferring the writing board is further provided, including a conveyor belt 71. The conveyor belt 71 is located on one side of the turntable 21, and a mechanical clamp 72 capable of multi-directional movement is provided at one end of the conveyor belt 71.

[0040] The working principle of this device is as follows. First, the surface sticker feeding mechanism 30 lifts the surface sticker to the processing position. Then, the turntable 21 rotates the processing position to transfer the surface sticker to the glue sticking mechanism 40. The segmental tape is stuck to the dust-proof paper of the surface sticker through the glue sticking mechanism 40. Subsequently, the turntable 21 continues to rotate, and the surface sticker with the tape is rotated to the glue tearing mechanism 50. The dust-proof paper is torn off by the chuck 51. Then, the turntable continues to rotate, and the surface sticker with the dust-proof paper torn off is transferred to the lower part of the assembly mechanism 60. During the processing of the surface sticker, the writing board transfer mechanism 70 transfers the writing board to be processed to the lower part of the assembly mechanism 60, and the surface sticker is placed on the writing board through the processing position. Thus, the pasting of the surface sticker is completed.

[0041] To achieve the effect of automatically cutting the tape and sticking it to the surface sticker, the glue sticking mechanism 40 includes a glue sticking main board 41. A displacement mechanism 42 is connected to the glue sticking main board 41. The displacement mechanism 42 can drive the glue sticking main board 41 to move horizontally and vertically. A tape placement board 43 is rotatably connected to the glue sticking main board 41. As Figure 4 shown, a control cylinder is connected below the glue sticking main board 41 to control the rotation of the tape placement board 43 through the control cylinder. A roller 44 is provided at one end of the tape placement board 43, and a tape is sleeved on the roller 44. A transfer board 45 is fixedly connected to the glue sticking main board 41. A liftable pressing roller 451 and a liftable cutter 452 are respectively provided on both sides of the transfer board 45. In this device, the lifting of the pressing roller 451 and the cutter 452 is realized through cylinders. The specific cylinder installation positions are as Figure 5 shown. The pressing roller is used to press the idle end of the tape onto the surface sticker. The tape is pulled out by changing the rotation of the glue sticking main board 41. Then, the tape is cut by the upward movement of the cutter 452. The pressing roller is driven to move by the horizontal displacement of the glue sticking main board 41, so as to press the cut tape onto the surface sticker.

[0042] The movement of the glue sticking main board 41 mainly includes horizontal and vertical movements. The displacement mechanism 42 includes a horizontal moving board 421. The horizontal moving board 421 can move horizontally relative to the machine table 10. A lead screw transmission mechanism is provided between the horizontal moving board 421 and the machine table 10 to control the horizontal movement of the horizontal moving board 421. The glue sticking main board 41 is slidably connected to the horizontal moving board 421. A moving cylinder 411 is provided at the end of the glue sticking main board 41. The moving cylinder 411 is fixed on the horizontal moving board 421. The output shaft of the moving cylinder 411 is fixedly connected to the glue sticking main board 41. The lifting of the glue sticking main board 41 is controlled by the moving cylinder 411. Through the comprehensive utilization of the above displacement mechanism 42, the expected movement effect of the glue sticking main board 41 is achieved.

[0043] When the tape tearing mechanism 50 tears the tape, it is necessary to control the chuck 51 to move horizontally. For this purpose, a chuck 51 moving mechanism is connected below the chuck 51. The chuck 51 moving mechanism includes a vertical plate 521 and a bottom plate 522. The chuck 51 is fixed to the end of the vertical plate 521. A chuck 51 moving cylinder 411 is fixed on the bottom plate 522. The vertical plate 521 is fixed on the output shaft of the chuck 51 moving cylinder 411. The lifting of the vertical plate 521 is controlled by the chuck 51 moving cylinder 411. The bottom plate 522 can move horizontally relative to the machine table 10. A same lead screw transmission mechanism is provided between the bottom plate 522 and the machine table 10. The rotation of the lead screw is controlled by a motor, so as to drive the sliding of the lead screw nut on the lead screw. The bottom plate 522 is fixed on the lead screw nut, so as to realize the control of the horizontal movement of the bottom plate 522.

[0044] In this equipment, the processing position is a T-shaped plate 22. The surface sticker is adsorbed on the lower surface of the T-shaped plate 22 during the processing and transportation. The tail end of the T-shaped plate 22 is fixed on the turntable 21. An annular groove 221 is provided on the lower surface of the T-shaped plate 22. The surface sticker is located in the annular groove 221. A relief notch 222 is provided at one corner of the annular groove 221. Most of the idle end of the tape on the surface sticker is located in the relief notch 222. The chuck 51 on the tape tearing mechanism 50 enters from the relief notch 222 and clamps the tape. A plurality of through holes are provided on the T-shaped plate 22. The through holes communicate with the annular groove 221. A vacuum suction head 223 is connected to the through holes. A pumping device is connected behind the vacuum suction head 223. A vacuum is formed in the annular groove 221 through the vacuum suction head 223, so as to adsorb the surface sticker in the annular groove 221.

[0045] To increase the feeding efficiency of the surface sticker feeding mechanism 30 in this equipment, a rotating rod 32 is fixed at the center of the carrier plate 31. A rotating motor is connected to the end of the rotating rod 32. The rotating motor can control the rotation of the carrier plate 31. Two arc-shaped positioning grooves 311 are symmetrically provided on the carrier plate 31. A positioning rod 33 is provided on the machine table 10. During the rotation of the carrier plate 31, the positioning effect is achieved through the engagement of the positioning rod 33 and the arc-shaped positioning grooves 311. At the same time, a plurality of vertical rods 312 are provided on the carrier plate 31. The vertical rods 312 enclose to form a storage bin. The surface stickers are placed in the storage bin. As Figure 2 shown, storage bins are respectively provided at both ends of the carrier plate 31, so as to increase the load capacity on the carrier plate 31. The two storage bins can be alternately fed, so as to avoid the problem of equipment downtime for feeding.

[0046] The assembly mechanism 60 includes a number of stop blocks 61, a first lifting block 62, a second lifting block 63 and a top block 64. The top block 64 is fixed in a vertical displacement relationship with the machine table 10. The stop blocks 61 are fixed to the upper surface of the T-shaped plate 22. A number of downwardly extending guide shafts 621 are fixed to the first lifting block 62. The guide shafts 621 penetrate through the stop blocks 61 and the T-shaped plate 22. For the convenience of arranging the guide shafts 621, through holes are provided on both the stop blocks 61 and the T-shaped plate 22, and the guide shafts 621 are slidably connected to the through holes. A guide rod 65 is provided between the T-shaped plate 22 and the second lifting block 63, and the first lifting block 62 is slidably connected to the guide rod 65. A lifting mechanism 66 is provided on the top block 64, and the first lifting block 62 is fixed to the end of the lifting mechanism 66. The lifting of the first lifting block 62 is controlled by the lifting mechanism 66, and then the lifting of the guide shafts 621 is controlled. Before the turntable 21 rotates, the guide shafts 621 need to be disengaged from the contact with the stop blocks 61 and the T-shaped plate 22, so that the turntable 21 can rotate freely. The plurality of guide shafts 621 surround and form a blanking bin that conforms to the outer shape of the surface sticker. When the guide circumference is in full contact with the placement surface of the writing board, the vacuum suction head 223 releases the vacuum suction force, and the surface sticker descends along the blanking bin onto the writing board. The blanking bin can not only guide but also play a positioning role, ensuring that the surface sticker can fall to the designated position, thereby ensuring the fitting effect between the surface sticker and the display screen.

[0047] Specifically, the lifting mechanism 66 includes a lifting motor 661 and a number of lifting cylinders 662. As Figure 8 shown, the lifting cylinders 662 are distributed on both sides of the lifting motor 661. A number of upwardly extending guide posts 622 are provided on the first lifting block 62. The guide posts 622 penetrate through the second lifting block 63, and the second lifting block 63 can freely lift along the guide posts 622. A transmission block 631 is fixed to the second lifting block 63. A transmission gear is provided inside the transmission block 631. An external tooth is provided at the end of one of the guide posts 622. A rack 663 is fixed to the end of the lifting motor 661. The transmission gear meshes with the rack 663 and the external tooth respectively. The lifting of the guide post 622 provided with the external tooth is controlled by the pulling of the rack 663. At the same time, a return spring 67 is sleeved on the guide post 622. Referring to Figure 8 it can be seen that the return spring 67 on the guide post 622 provided with the external tooth is arranged between the first lifting block 62 and the T-shaped plate 22, and the remaining return springs 67 are arranged between the second lifting block 63 and the top block 64. The return spring 67 is mainly used to ensure the stable return effect of the first lifting block 62 and the second lifting block 63.

[0048] In addition, in this device, a rotating shaft 11 is provided at the center of the turntable 21, and a fixed disk 12 is provided at the top of the rotating shaft 11. The fixed disk 12 is fixed in position relative to the machine table 10, and the top plate is fixed to the fixed disk 12. To ensure complete adhesion between the surface mount, the touch screen, and the writing board, a cross frame 13 is provided on the fixed disk 12, and a connecting frame 14 is slidably connected to the cross frame 13. The movement of the connecting frame 14 is also achieved through a lead screw drive mechanism. At the same time, a flattening roller 15 is provided at the bottom of the connecting frame 14. The movement of the connecting frame 14 drives the flattening roller to move horizontally. As Figure 3 can be seen, the flattening roller is preferably arranged above the placement position of the writing board.

[0049] In this device, the conveyance of the writing board is mainly achieved through the conveyor belt 71. The conveyor belt 71 includes a loading conveyor belt 711 and an unloading conveyor belt 71271. There is a vacant position between the loading conveyor belt 711 and the unloading conveyor belt 71271. A rotatable material tray 73 is provided in the vacant position. A motor is provided below the material tray 73 to control the rotation of the material tray 73. Placement positions are formed on the material tray 73 through convex shafts. The placement positions are in two groups and are located on both sides of the material tray 73 respectively. The writing board is placed in the placement positions. The mechanical clamp 72 is provided above the conveyor belt 71. A cylinder for controlling the lifting is connected to the mechanical clamp 72. The lifting of the mechanical clamp 72 is used to grab the writing board from the loading conveyor belt 711 onto the material tray 73. A lead screw drive mechanism for controlling the horizontal movement of the mechanical clamp 72 is also provided thereon. The horizontal movement of the mechanical clamp 72 is used to transfer the writing board from the material tray 73 to the unloading conveyor belt 71271, thereby completing the process of loading and unloading the writing board.
