[0023] Example 1: Reference Figure 1-3 A mobile phone touch screen hot pressing mechanism shown in the figure comprises a hot press machine 1 for assembling the mobile phone touch screen and a cooling machine 2 for cooling the mobile phone touch screen after assembly. The hot press machine 1 is provided with a hot press plate driven by a cylinder for hot pressing the mobile phone touch screen, and the cooling machine 2 is provided with a water cooling plate driven by a cylinder for cooling the mobile phone touch screen after hot pressing. The cylinder, the hot press plate and the water cooling plate are all prior art. A conveying unit for conveying the mobile phone touch screen is provided between the hot press machine 1 and the cooling machine 2. The conveying unit comprises a heat press plate fixedly connected to the hot press machine 1 and the cooling machine 2. The mounting seat 3 between the machines 2 is provided with a pair of interconnected slide grooves 4, and the pair of slide grooves 4 are slidably connected with a limit plate 9 for conveying the mobile phone touch screen. When in use, the hot press machine 1 is used to perform hot pressing processing on the mobile phone touch screen through the limit plate 9, and then the hot pressed mobile phone touch screen on the limit plate 9 is driven by the slide groove 4 to move to the cooling machine 2 for cooling, and at the same time, the new mobile phone touch screen to be hot pressed is moved to the hot press machine 1 for continued hot pressing, and this cycle is repeated to achieve continuous hot pressing and cooling work, replacing the existing hot pressing cooling structure, improving the hot pressing effect, and having high practicality.

[0024] The transmission unit also includes a motor 5 installed at the bottom of the mounting base 3, and the output end of the motor 5 is rotatably connected to the first gear 6. A pair of racks 7 are slidably connected at the position of the bottom end of the mounting base 3 corresponding to the slide groove 4, and the two sides of the first gear 6 are respectively meshed with a pair of racks 7. The slide groove 4 is a through setting, and a first sliding shaft 8 is slidably connected in the slide groove 4, and the bottom end of the first sliding shaft 8 is fixedly connected to the rack 7, and a limit plate 9 is installed on the top of the first sliding shaft 8. When in use, the first gear 6 is driven to rotate by the motor 5, and the two racks 7 are driven to slide by the first gear 6, thereby driving the two limit plates 9 to move in opposite directions. One of the mobile phone touch screens to be hot pressed is moved to the hot press 1 for hot pressing processing, and the other mobile phone touch screen after hot pressing is synchronously moved to the cooler 2 for cooling. In this way, continuous hot pressing and cooling work is achieved, replacing the existing cooling structure and further improving work efficiency.

[0025] A reversing unit for driving the limiting plate 9 to move and reverse is arranged between the first sliding shaft 8 and the limiting plate 9. The reversing unit includes a second gear 10 fixedly connected to the top end of the first sliding shaft 8. A tooth groove 11 is provided at the middle position of the slide groove 4, and the second gear 10 is meshed with the tooth groove 11. A connecting rod 12 is fixedly connected to the second gear 10.

The limiting plate 9 is fixedly connected to the rotating rod 13. A torsion spring is arranged between the connecting rod 12 and the rotating rod 13.

[0026] When the motor 5 drives the limit plate 9 on the first sliding shaft 8 to move toward the hot press machine 1 or the cooling machine 2, first, the first sliding shaft 8 and the second sliding shaft 14 both slide in the sliding groove 4. As the second sliding shaft 14 moves to the arc groove section of the sliding groove 4, the rotating rod 13 is driven to rotate, thereby driving the limit plate 9 to move to the hot pressing position on the hot press machine 1. After the hot pressing is completed, the second sliding shaft 14 returns from the arc groove section to the straight groove section. As the mobile phone touch screen moves toward the cooling machine 2 after hot pressing, first the second gear 10 moves to engage with the tooth groove 11. At this time, the second sliding shaft 14 is aligned with the semi-annular groove 15. As it continues to move, it drives the second gear 10 to rotate, thereby driving the second sliding shaft 14 to slide in the semi-annular groove 15, so that the connecting rod 12 rotates, thereby driving the limit plate 9 on the rotating rod 13 to rotate, realizing reversal, and then continues to move until the limit plate 9 moves to the cooling position on the cooling machine 2, thereby realizing accurate cold zone processing, simple structure, high movement accuracy, and improved practicality.
