Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Refer to the attached Figure 1 - attached Figure 6 As shown in the figure, a mobile phone screen hot pressing device provided by the present invention includes a base 1. A plurality of fixed rods 2 are fixedly arranged at the top of the base 1. A top plate 3 is fixedly arranged at the tops of the plurality of fixed rods 2. A fixed plate 6 is fixedly arranged outside the plurality of fixed rods 2. A hot pressing platform 7 and two support plates 8 are respectively fixedly arranged at the top of the fixed plate 6. A cylinder 4 is arranged at the top of the top plate 3. The output end of the cylinder 4 is fixedly connected with a movable plate 5. A hot pressing device body 17 is fixedly arranged at the bottom of the movable plate 5. A driving mechanism is arranged at the bottom of the movable plate 5;

[0030] The driving mechanism includes two driving components. Each driving component includes a rack 9. The top of the rack 9 is fixedly connected with the bottom of the movable plate 5. A first gear 10 is arranged on one side of the rack 9. A transmission shaft 12 is arranged inside the first gear 10. A one-way bearing 11 is fixedly connected between the first gear 10 and the transmission shaft 12. Two synchronous pulleys 13 are fixedly sleeved outside the transmission shaft 12. Synchronous belts 14 are arranged at the tops of the two synchronous pulleys 13. A conveyor belt 15 is fixedly arranged at the tops of the two synchronous belts 14. A plurality of mobile phone screen bodies 16 are arranged at the top of the conveyor belt 15. Two positioning units are arranged at the top of the conveyor belt 15;

[0031] In this implementation, to achieve the purpose of automatically conveying the mobile phone screen body 16, the drive shaft 12 rotates to make the synchronous pulley 13 drive the synchronous belt 14 to move. The movement of the synchronous belt 14 drives the mobile phone screen body 16 to move through the conveyor belt 15, so that the mobile phone screen body 16 moves to the bottom of the hot pressing device body 17. At the same time, the positioning unit clamps the mobile phone screen body 16 moving to the top of the conveyor belt 15, facilitating the hot pressing device body 17 to quickly hot press the mobile phone screen body 16. After the hot pressing is completed, the output end of the cylinder 4 drives the movable plate 5 to move upward, causing the hot pressing device body 17 to reset, and at the same time driving the rack 9 to move upward. Due to the characteristic of the one-way bearing 11 rotating in one direction, at this time, when the first gear 10 rotates, it idles around the drive shaft 12 through the one-way bearing 11, preventing the drive shaft 12 from rotating, so that the conveyor belt 15 can only convey the mobile phone screen body 16 in one direction, thus forming an assembly line processing method and improving production efficiency;

[0032] Among them, to achieve the purpose of positioning the mobile phone screen body 16 moving to the bottom of the hot pressing device body 17, the following technical solution is adopted by this device: The positioning unit includes a second gear 18, and the second gear 18 meshes with the rack 9. A threaded rod 19 is fixedly inserted inside the second gear 18. One end of the threaded rod 19 is connected to one side wall of the fixed plate 6 through a bearing, and the other end of the threaded rod 19 is connected to the support plate 8 through a bearing. A threaded block 20 is sleeved outside the threaded rod 19, and the threaded rod 19 is threadedly connected to the threaded block 20. The threaded block 20 is arranged on the top of the fixed plate 6 and is slidably connected to the top of the fixed plate 6. One end of the threaded block 20 is fixedly provided with a clamping block 21. When the rack 9 moves downward, the second gear 18 rotates, the rotation of the second gear 18 drives the threaded rod 19 to rotate, and the rotation of the threaded rod 19 drives the threaded block 20 to move towards the center of the conveyor belt 15 through the thread. The movement of the threaded block 20 drives the clamping block 21 to clamp the mobile phone screen body 16 moving to the top of the conveyor belt 15;

[0033] Among them, to achieve the purpose that the movable plate 5 can move longitudinally, the following technical solution is adopted by this device: The cylinder 4 is fixedly arranged on the top of the top plate 3, the output end of the cylinder 4 penetrates through the top of the top plate 3, the movable plate 5 is sleeved outside a plurality of fixed rods 2 and is slidably connected to the plurality of fixed rods 2. When the cylinder 4 is started, the output end of the cylinder 4 moves longitudinally to drive the movable plate 5 to move longitudinally. The longitudinal movement of the movable plate 5 is restricted by the fixed rods 2 to prevent the movable plate 5 from tilting when moving;

[0034] Among them, in order to prevent interference between the first gear 10, the synchronous pulley 13, and the second gear 18 and the fixed plate 6 during rotation, the following technical solutions are adopted in this device: Two rectangular obstacle avoidance grooves and two arc-shaped obstacle avoidance grooves are respectively provided inside the fixed plate 6. The rack 9 meshes with the first gear 10. The rack 9 penetrates through the rectangular obstacle avoidance groove and is slidably connected to the rectangular obstacle avoidance groove. The transmission shaft 12 penetrates through the base 1 and is connected to the base 1 through a bearing. The synchronous pulley 13 meshes with the synchronous belt 14. The synchronous pulley 13 penetrates through the arc-shaped obstacle avoidance groove. The conveyor belt 15 is arranged on the top of the hot pressing platform 7 and is slidably connected to the top of the hot pressing platform 7. The rack 9 penetrates through the rectangular obstacle avoidance groove to drive the first gear 10 and the second gear 18, and the synchronous pulley 13 penetrates through the arc-shaped obstacle avoidance groove to drive the synchronous belt 14.

[0035] The usage process of this utility model is as follows: When using this utility model, the cylinder 4 is connected to a pneumatic device to provide a power source for the start of the cylinder 4. When it is necessary to hot press the mobile phone screen body 16, the cylinder 4 is started. The output end of the cylinder 4 moves downward, causing the movable plate 5 to drive the rack 9 and the hot pressing device body 17 to move downward. When the rack 9 moves downward, the first gear 10 and the second gear 18 rotate. The rotation of the first gear 10 drives the transmission shaft 12 to rotate through the characteristic of a large resistance in one-way rotation of the one-way bearing 11 (A one-way bearing can rotate freely in one direction and is locked in the other direction. A one-way bearing is also called an overrunning clutch, which is named according to different industries and functions. Inside the metal shell of the one-way bearing, there are many rollers, needle rollers or ball bearings, and the shape of its rolling seat (hole) makes it only roll in one direction and generate a large resistance in the other direction). The rotation of the transmission shaft 12 causes the synchronous belt 14 to move through the synchronous pulley 13. The movement of the synchronous belt 14 drives the mobile phone screen body 16 to move through the conveyor belt 15, so that the mobile phone screen body 16 moves to the bottom of the hot pressing device body 17. At the same time, the rotation of the second gear 18 drives the threaded rod 19 to rotate. The rotation of the threaded rod 19 drives the threaded block 20 to move towards the center of the conveyor belt 15 through the thread. The movement of the threaded block 20 drives the clamping block 21 to clamp the mobile phone screen body 16 that has moved to the top of the conveyor belt 15, facilitating the hot pressing device body 17 to quickly hot press the mobile phone screen body 16. When the hot pressing is completed, the output end of the cylinder 4 drives the movable plate 5 to move upward, causing the hot pressing device body 17 to reset, and at the same time driving the rack 9 to move upward, so that the clamping block 21 resets to release the clamping of the mobile phone screen body 16. At the same time, due to the characteristic of one-way rotation of the one-way bearing 11, at this time, when the first gear 10 rotates, it idles around the transmission shaft 12 through the one-way bearing 11, preventing the transmission shaft 12 from rotating, and thus enabling the conveyor belt 15 to only convey the mobile phone screen body 16 in one direction, thereby forming an assembly line processing method and improving production efficiency.

[0036] The above are only the preferred embodiments of the present utility model. Any person skilled in the art may modify the present utility model by using the technical solutions described above or modify it into equivalent technical solutions. Therefore, any simple modification or equivalent replacement made according to the technical solutions of the present utility model falls within the scope of protection required by the present utility model.
