[0020] Example

[0021] To address the aforementioned technical problems, this embodiment provides an automatic bonding device for touchscreens and LCDs, such as... Figure 1-2 As shown, the system includes a machine base 10, a first conveyor line 20, a second conveyor line 30, and a third conveyor line 40 arranged side-by-side on the machine base 10. Several assembly platforms 50 are slidably mounted on the second conveyor line 30. A multi-axis drive module 70 is mounted on the machine base 10, and an adsorption component 60 is mounted on the drive end of the multi-axis drive module 70. The multi-axis drive module 70 drives the adsorption component 60 to move above the first conveyor line 20, the second conveyor line 30, and the third conveyor line 40. The first conveyor line 20 is used to load touchscreens, and LCD modules with adhesive tape are loaded onto the second conveyor line 40. The assembly platform 50 of line 30 then drives the adsorption component 60 through the multi-axis drive module 70 to pick up the touch screen on the first conveyor line 20 and place the touch screen on the LCD module, so that the LCD module and the touch screen are bonded. A detection component 80 is set on one side of the first conveyor line 20. The bonded LCD module and touch screen are transferred to the detection component 80 for visual inspection, and then the inspected LCD module and touch screen are transferred to the third conveyor line 40 for unloading. Automated feeding and bonding improve production efficiency and bonding quality, thereby meeting the increasing demand for production capacity.

[0022] Specifically, such as Figure 3-4As shown, the first conveyor line 20 includes several carrier platforms 21, limiting blocks 23 disposed on both sides of the carrier platforms 21, and a first driver 22 disposed below the machine base 10. The first driver 22 is used to drive the carrier platforms 21 to move. The first driver 22 can be a drive structure composed of a motor and a lead screw. The first driver 22 drives the carrier platforms 21 to move back and forth. After an external robotic arm loads a touchscreen onto the carrier platform 21 of the first conveyor line 20, the first driver 22 drives the carrier platform 21 to approach the multi-axis drive module 70. The multi-axis drive module 70 then drives the adsorption assembly 60 to move above the carrier platform 21, thereby picking up the touchscreen from the carrier platform 21 and transferring it to the assembly platform 50 for assembly. Positioning protrusions 211 are provided at the four corners of the carrier surface of the carrier platform 21. The four positioning protrusions 211 form a space for placing the touchscreen. After the external robotic arm loads the touchscreen onto the carrier platform 21, the positioning protrusions 211 limit the touchscreen, ensuring that the touchscreen does not shift position.

[0023] Furthermore, a lifting driver 25 is slidably disposed below the machine base 10. The lifting driver 25 is connected to the drive end of the first driver 22, and a lifting plate 24 is connected to the drive end of the lifting driver 25. Several support platforms 21 are disposed on the lifting plate 24. The lifting driver 25 can be a cylinder, which can drive the lifting plate 24 to move up and down, thereby driving the support platforms 21 to move up and down, so as to adjust the height position of the support platforms 21 according to the actual working conditions. The lifting driver 25 is slidably disposed below the machine base 10 through a slide rail and a slider, and the first driver 22 drives the lifting driver 25 to move horizontally, thereby driving the lifting plate 24 and the support platforms 21 to move back and forth horizontally.

[0024] Furthermore, baffles 26 are provided on both sides of the lifting plate 24. The two baffles 26 are connected by a connecting shaft 27. Limiting blocks 23 are installed on the baffles 26, and the distance between the baffles 26 can be adjusted by the connecting shaft 27, so that there is enough space between the baffles 26 for the support platform 21 to move. During the movement, the limiting blocks 23 on the baffles 26 further limit the touch screen.

[0025] Furthermore, the assembly platform 50 is slidably mounted on the machine base 10 via a slide rail and a slider. The second conveyor line 30 includes a linear drive module, which drives the assembly platform 50 to move back and forth along the slide rail. An adsorption platform 51 is provided on the assembly platform 50, with adsorption holes 53 on its surface. Positioning blocks 52 are arranged around the adsorption holes 53 on the adsorption platform 51. A loading robot then places an LCD module with adhesive tape on its surface onto the adsorption platform 51, and the LCD module is adsorbed and fixed through the adsorption holes 53. The second conveyor line 30 moves the assembly platform 50 below the multi-axis drive module 70. The multi-axis drive module 70 and the adsorption assembly 60 then work together to place the touchscreen onto the LCD module for bonding, thus completing the automatic loading and bonding process.

[0026] Furthermore, after the touchscreen and LCD module are bonded, it is necessary to check for positional deviations. Therefore, the bonded touchscreen and LCD module need to be transferred to the detection component 80 for inspection. The detection component 80 includes a placement stage 81, a detector 82 located above the placement stage 81, and a second driver 83 located below the multi-axis drive module 70. The drive end of the second driver 83 is connected to the detector 82, which can be a vision camera. The second driver 83 drives the detector 82 to adjust its position in the horizontal direction to acquire an image of the product. After the bonded touchscreen and LCD module are placed on the placement stage 81, the detector 82 takes a picture of the bonded touchscreen and LCD module for visual inspection to determine whether the bonding quality is qualified, thereby improving the bonding quality. A conveyor belt assembly 90 is also provided on one side of the detection component 80. The multi-axis drive module 70 and the adsorption component 60 transfer unqualified products to the conveyor belt assembly 90, which then conveys and unloads the unqualified products. Products that pass inspection are transferred to the third conveyor line 40. After reaching the end of the third conveyor line 40, a robotic arm transfers the bonded product to the next assembly process. The third conveyor line 40 is equipped with presence sensors 41 at both its beginning and end. When a bonded product reaches the beginning of the third conveyor line 40, the presence sensor 41 detects the product's arrival, the third conveyor line 40 starts, and transports the product to the end of the line. The robotic arm then transfers the product to the next process.

[0027] Furthermore, in the above scheme, the driving end of the second driver 83 is provided with a mounting plate, and the mounting plate is provided with an adjusting screw 84 arranged in the vertical direction. The adjusting screw 84 is threadedly connected to the detector 82, and the height position of the detector 82 can be adjusted by twisting the adjusting screw 84.

[0028] Furthermore, the multi-axis drive module 70 includes a first drive module 71, a second drive module 72 disposed at the drive end of the first drive module 71, and a third drive module 73 disposed at the drive end of the second drive module 72. The drive directions of the first drive module 71, the second drive module 72, and the second drive module 73 are perpendicular to each other, thereby enabling the adsorption assembly 60 to move in three axial directions. The first drive module 71, the second drive module 72, and the second drive module 73 can be linear drive structures composed of a motor and a lead screw.

[0029] In summary, the solution of this application automates the feeding and bonding process by arranging a first, second, and third conveyor line side by side on a machine. Several assembly platforms are slidably arranged on the second conveyor line. A multi-axis drive module is installed on the machine to drive the adsorption component to move above the first, second, and third conveyor lines. LCD modules with adhesive tape are fed onto the assembly platform of the second conveyor line. The adsorption component picks up the touch screen from the first conveyor line and places the touch screen on the LCD module, thus bonding the LCD module and the touch screen. The bonded LCD module and touch screen are then transferred to a detection component for visual inspection, and then transferred to the third conveyor line for unloading. This automated feeding and bonding process improves production efficiency and bonding quality, thereby meeting the increasing demand for production capacity.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the scope of protection of this technical solution.
