[0022] Embodiment: An edge grinding device for OLED mobile phone touch screen production, as Figures 1 - 4As shown in the figure, it includes an installation cabinet 1, an adsorber 2, a support base 3, a lifting mechanism 4, a special-shaped rod 5, a cover plate 51, a load-bearing arm 6, a motor I 61, a lead screw 62, an installation bracket, a cylinder 8, a guide rail 81, a motor II 9, a connecting seat 10, a grinding wheel 11 and a pulley group 12. Cylindrical support legs are detachably provided around the bottom of the installation cabinet 1. There are two cabinet doors on the installation cabinet 1. The installation cabinet 1 is a cabinet with a partition in the middle inside, and the inside of the installation cabinet 1 is used to place the trimmed touch screen. The adsorber 2 is set at the middle front position on the top of the installation cabinet 1 by screws. A plurality of evenly distributed adsorption ports are opened on the suction cup of the adsorber 2. Since the touch screen is light in weight, when the adsorber 2 is started, the touch screen will be adsorbed and fixed on the adsorber 2. The support base 3 is welded at the middle rear position on the top of the installation cabinet 1. An installation groove is opened on the front side of the top of the support base 3, and a load-bearing bracket is provided at the rear of the support base 3. The lifting mechanism 4 is vertically installed on the installation groove opened in the middle of the top of the support base 3 by screws. The special-shaped rod 5 is slidably connected to the outside of the driving part of the lifting mechanism 4. The special-shaped rod 5 is in an L shape with the front end lower and the rear end higher. A rectangular mounting plate is provided at the front end of the special-shaped rod 5. The front end of the special-shaped rod 5 is higher than the top of the adsorber 2, and the front end of the special-shaped rod 5 is located at the center position of the top of the adsorber 2. When the driving part of the lifting mechanism 4 rotates counterclockwise, the special-shaped rod 5 is driven to slide downward. On the contrary, when the driving part of the lifting mechanism 4 rotates clockwise, the special-shaped rod 5 is driven to slide upward. The cover plate 51 is connected to the rectangular mounting plate at the front end of the special-shaped rod 5 by screws, and the outer contour of the cover plate 51 is smaller than the outer contour of the suction cup of the adsorber 2. When the adsorber 2 adsorbs the touch screen, and as the special-shaped rod 5 slides downward, the cover plate 51 presses the touch screen to further fix the touch screen on the adsorber 2, so as to more stably perform the subsequent grinding operation. There are two load-bearing arms 6 that are symmetric left and right. The two load-bearing arms 6 are both installed on the mounting bracket 7 of the support base 3 in a reverse manner by screws. The two load-bearing arms 6 are in a parallel state. There are two motors I 61 that are symmetric left and right. The two motors I 61 are installed at the ends of the two load-bearing arms 6 in a reverse manner by bolts. The two motors I 61 are in a parallel state, and the output ends of the two motors I 61 are opposite. There are two lead screws 62 that are symmetric left and right. The two lead screws 62 are respectively rotatably arranged at the rear sides of the adjacent two load-bearing arms 6 by the driving parts of the motors I 61 in a reverse manner, and the two lead screws 62 are in a parallel state. After the two lead screws 62 are started, they rotate in opposite motion states. There are two installation brackets 7 that are symmetric left and right. The two installation brackets 7 are respectively slidably connected to the outside of the two load-bearing arms 6 through the two lead screws 62. When the two motors I 61 are started and operated simultaneously, the motors I 61 drive the two lead screws 62 to rotate synchronously in opposite directions. While the two lead screws 62 are rotating, they will drive the two installation brackets 7 to slide inward or outward. The movement trajectories of the two installation brackets 7 are opposite. Installation plates are provided on the inner sides of the two installation brackets 7, and the front ends of the two installation brackets 7 extend to the front end of the installation cabinet 1. There are two cylinders 8 that are symmetric left and right. The two cylinders 8 are respectively installed on the installation plates of the two installation brackets 7.Moreover, the telescopic ends of the two cylinders 8 face forward. There are two symmetrically arranged guide rails 81 on the left and right. The two guide rails 81 are respectively arranged on the inner sides of the two mounting brackets 7 by screws. There are two symmetrically arranged motors II 9 on the left and right. The two motors II 9 are respectively slidably mounted on the two guide rails 81 through connecting sliders. The ends of the piston rods of the two cylinders 8 are respectively connected to the mounting sliders of the two motors II 9 by screws. The two cylinders 8 are slidably matched with the two motors II 9. The movement trajectories of the two cylinders 8 are the same. When the two cylinders 8 operate, they start synchronously. The telescopic distances of the piston rods of the two cylinders 8 are the same. There are two symmetrically arranged connecting seats 10 on the left and right. The two connecting seats 10 are composed of two adjacent discs. The discs on the outer sides of the two connecting seats 10 are respectively key-connected to the outer sides of the output shafts of the two motors II 9.

Grinding wheels 11 are rotatably connected to the tops of the discs on the inner sides of the two connecting seats 10 through rotating shafts. There are two symmetrically arranged pulley groups 12 on the left and right. The two pulley groups 12 are respectively key-connected to the bottoms of the two connecting seats 10. The driving wheels of the two pulley groups 12 are both connected to the output shafts of the two motors II 9. The driven wheels of the two pulley groups 12 are both connected to the two grinding wheels 11 through rotating shafts. When the motors II 9 are started to operate, the two pulley groups 12 will drive the two grinding wheels 11 to rotate synchronously.,

[0023] When it is necessary to grind the edges of the cut mobile phone touch screen, first place the mobile phone touch screen on the adsorber 2. After the adsorber 2 is started, it adsorbs and fixes the mobile phone touch screen on the adsorber 2. Then start the lifting mechanism 4. The lifting mechanism 4 drives the special-shaped rod 5 to drive the cover plate 51 to slide downward to further fix the mobile phone touch screen on the adsorber 2, improving the stability during the grinding process. Then start the two motors II 9 and the two motors I 61 to drive the two lead screws 62 to rotate. While the two lead screws 62 are rotating, they will drive the two mounting brackets 7 to slide inward, so that the grinding wheels 11 mounted on the two mounting brackets 7 approach the left and right edges of the mobile phone touch screen. At the same time, start the two cylinders 8 to drive the two motors II 9 to slide back and forth on the guide rails 81 so that the two grinding wheels 11 perform edge trimming and grinding on the left and right edges of the mobile phone touch screen. When the left and right edges of the mobile phone touch screen are ground, control the two motors I 61 to drive the two lead screws 62 to continue rotating, so that the two mounting brackets 7 slide inward and drive the grinding wheels 11 to continue approaching the mobile phone touch screen. At the same time, control the piston rods of the two cylinders 8 to shorten, so that the two grinding wheels 11 grind the rear edge of the mobile phone touch screen. Similarly, grind the front edge of the mobile phone touch screen. After the grinding is completed, turn off each motor and the cylinder 8, and then control the lifting mechanism 4 to drive the special-shaped rod 5 to drive the cover plate 51 to slide upward. Finally, turn off the adsorber 2 to remove the mobile phone touch screen and complete the operation.
