[0046] Embodiment 1:

[0047] See also Figure 1-4 The present invention provides a technical solution: an automatic feeding, detection, bonding and positioning device for a gasket for a display screen bracket, comprising:

[0048] A gasket feeding mechanism 1 is provided with an unwinding disc 11 and a rewinding frame 12, and a plurality of guide roller assemblies are arranged between the unwinding disc 11 and the rewinding frame 12;

[0049] The film-tearing mechanism 2 comprises a slide 21 driven to slide on a guide rail 22, a second support plate 23 and a film-tearing guide roller 24 are respectively arranged at the upper and lower ends of the slide 21, an auxiliary guide roller 25 is arranged below the film-tearing guide roller 24 on the guide rail 22, a material belt 100 extends downward from the rear end of the second support plate 23 and is wound in an S shape on the film-tearing guide roller 24 and the auxiliary guide roller 25, and its ends are wound on the guide roller assembly and are respectively wound and positioned on the unwinding disk 11 and the winding frame 12; wherein, according to Figure 1 As shown, the left side is the front end of the device, and the right side is the rear end of the device;

[0050] A mechanical arm mechanism 3, on which an adjustment mechanism 4 is arranged so as to be able to rise and fall and rotate;

[0051] A grabbing mechanism 5, which is docked with the bottom of the adjusting mechanism 4, and is used to grab the gasket 110 on the material strip 100 and press it onto the bracket plate;

[0052] A detection mechanism 6, which is used to detect the gasket 110;

[0053] An assembly turntable 7 is rotatably arranged on a workbench, and is provided with a plurality of workstations for positioning the support plate.

[0054] The assembly device of the gasket on the display screen bracket uses the gasket feeding mechanism to reel in and out the material tape, and the unrolled material tape is wound around the guide roller assembly and the film tearing mechanism. When the gasket on it is demoulded, the mechanical arm mechanism and the adjustment mechanism drive the grasping mechanism to move to the second support plate to grasp the non-sticky surface of the gasket. After that, the slide moves forward first, so that the film tearing guide roller drives the rear end of the material tape to move forward, so that the part of the material tape bonded to the gasket at the front end is gradually separated from the gasket, so as to achieve non-destructive film tearing of the sticky surface of the gasket. After that, the slide moves backward and resets, and the gasket feeding mechanism conveys the material tape, so that the next batch of gaskets moves to the rear end edge of the second support plate, so as to facilitate the next round of gasket film tearing and loading. The device has a simple structure and the film tearing operation is simple and fast. The gasket is moved to the detection mechanism by the grasping mechanism for gasket appearance and quality inspection. The unqualified ones are conveyed to the defective product collection area, and the qualified ones are conveyed to the assembly turntable, and are pressed onto the display screen bracket plate by the grasping mechanism to achieve the bonding positioning of the gasket.

The pre-tightening sleeve 19 can realize elastic tensioning of the material tape 100, and shave and clean the non-sticky surface of the material tape 100 when the material tape 100 is conveyed, so as to ensure the grasping stability of the subsequent grasping mechanism 5.

[0056] The guide rail 22 is provided with a first support plate 14 at the front end of the slide 21, and a pressure plate 16 is provided on the top of the first support plate 14 which is raised and lowered by a first driving device 15, so that when the film tearing mechanism 2 tears the gasket 110 on the material strip 100, the front end of the material strip 100 is clamped and positioned so that the part between the pressure plate 16 and the second support plate 23 remains horizontal, thereby cooperating with the horizontal sliding of the slide 21 to realize efficient gasket 110 film tearing.

[0057] A guide surface 26 extending toward the film tearing guide roller 24 is provided at the bottom of the rear end of the second support plate 23. The guide surface 26 is a wedge-shaped surface or an arc-shaped surface. When the film tearing guide roller 24 pulls the rear end of the material strip 100, the guide surface 26 can guide the torn material strip 100 partially, thereby further improving the film tearing efficiency of the gasket 110.

[0058] The mechanical arm mechanism 3 includes a base, a first swing arm 31 driven to rotate on the base, and a second swing arm 32 driven to rotate on the first swing arm 31, and the adjustment mechanism 4 is arranged on the second swing arm 32. In this way, the flexibility of the mechanical arm mechanism 3 is ensured, and the convenience and efficiency of the rough adjustment of the position of the grasping mechanism 5 are achieved.

[0059] The detection mechanism 6 includes a lampshade, a searchlight 61 arranged in the lampshade, and a sensing device positioned in a groove on the top surface of the workbench. When in use, the gasket 110 is moved between the two lampshades by the grasping mechanism 5, the searchlight 61 illuminates the gasket 110, and the sensing device detects and identifies its surface to ensure that the quality of the assembled gasket 110 meets the standard.

When the gasket 110 thereon is demolded, the mechanical arm mechanism 3 and the adjustment mechanism 4 drive the grasping mechanism 5 to move to the second support plate 23, wherein the mechanical arm mechanism 3 and the adjustment mechanism 4 respectively perform coarse and fine adjustment on the position of the grasping mechanism 5 to grasp the non-sticky surface of the gasket 110, and then the sliding The seat 21 moves forward first, so that the film tearing guide roller 24 drives the rear end of the material belt 100 to move forward, so that the part of the front end of the material belt 100 that is bonded to the gasket 110 gradually separates from the gasket 110, and the non-destructive film tearing of the adhesive surface of the gasket 110 is achieved. Then the slide seat 21 moves backward and resets, and the gasket feeding mechanism 1 conveys the material belt 100, so that the next batch of gaskets 110 moves to the rear end edge of the second support plate 23, so as to facilitate the next round of gaskets 110 to tear the film and load the material. The device structure is simple, and the film tearing operation is simple and fast. The device structure changes in this process are as follows Figure 2-4 As shown; the gasket 110 is moved to the inspection mechanism 6 by the grasping mechanism 5, and the appearance and quality inspection of the gasket 110 are carried out. The unqualified ones are transported to the defective product collection area, and the qualified ones are transported to the assembly turntable 7, and are pressed onto the display screen bracket plate by the grasping mechanism 5 to achieve the bonding and positioning of the gasket 110. The display screen bracket plate assembled with the gasket 110 is transported to the outside of the workbench driven by the rotating assembly turntable 7 to facilitate unloading, and the unassembled display screen bracket plate is transported to the corresponding position for the next round of gasket 110 assembly. The above processes all adopt continuous and integrated automatic control. The structural adjustment of the mechanical arm mechanism 3 and the adjustment mechanism 4 relies on the precise control programming of the moving angle and distance, and is combined with the position sensing equipment to perform real-time position sensing and position correction of the grasping mechanism 5 to ensure refined operation.
