Different thicknesses and materials of transparent plates require different amounts of radiant heat. However, the radiation intensity between the infrared heater and the transparent plate is not easy to adjust, which may result in the transparent plate not reaching the softening point or being over-softened, thus affecting the quality of the transparent plate processing.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides an infrared heating transparent plate preforming equipment, including a processing frame 1. A positioning mechanism 3 is installed on the top side of the processing frame 1, and a heating mechanism 2 is installed on the bottom side of the processing frame 1. The heating mechanism 2 includes an electric push rod 21, one end of which is fixedly connected to one side of the processing frame 1, and the other end of which is fixedly connected to a moving plate 22. A connecting rod 26 is fixedly connected to one side of the moving plate 22, and one end of the connecting rod 26 is fixedly connected to a first heat insulation cover 23. An infrared heater 2 is fixedly connected inside the first heat insulation cover 23. 7. A second insulation cover 28 is slidably sleeved on the inner side of the first insulation cover 23. One end of the second insulation cover 28 is fixedly connected to one side of the processing frame 1, and a forming lower mold 24 is fixedly connected to the other side of the processing frame 1. A support plate 25 is fixedly connected to one side of the processing frame 1, and the middle part of the support plate 25 is fixedly connected to the outside of the electric push rod 21. First guide rods 29 are slidably connected to the four corners of the heating mechanism 2. One end of the four first guide rods 29 is fixedly connected to one side of the processing frame 1, and the other end of the four first guide rods 29 is fixedly connected to one side of the support plate 25.

[0023] First, the transparent plate is placed on the lower forming mold 24. The electric push rod 21 drives the moving plate 22 to move. The moving plate 22 slides outside the first guide rod 29. The fixed moving plate 22 moves linearly. The movement of the moving plate 22 drives the connecting rod 26 and the infrared heater 27 to move in sequence. During the movement of the infrared heater 27, the first heat insulation cover 23 slides outside the second heat insulation cover 28, keeping the cavity between the first heat insulation cover 23 and the second heat insulation cover 28 isolated from the outside. At the same time, the first heat insulation cover 23 and the second heat insulation cover 28 are both made of heat insulation material, which can reduce the loss of heat from the infrared heater 27. By adjusting the position of the infrared heater 27, the distance between the infrared heater 27 and the transparent plate can be adjusted. By adjusting the distance, the heating speed of the transparent plate can be precisely controlled to reach the required forming temperature.

[0024] Example 2: Figure 1 and Figure 4 As shown, the positioning mechanism 3 includes a fixed plate 31, the outer side of which is fixedly connected to the inner side of the processing frame 1. A hydraulic cylinder 32 is fixedly connected to the top side of the fixed plate 31. One end of the hydraulic cylinder 32 passes through one side of the fixed plate 31 and is fixedly connected to an upper pressure mold 33. Second guide rods 34 are fixedly connected to the four corners of the fixed plate 31. One end of each of the four second guide rods 34 is fixedly connected to one side of the processing frame 1 at the four corners. The outer sides of the four second guide rods 34 are slidably connected to the four corners of the upper pressure mold 33. A telescopic rod 37 is fixedly connected to one side of the upper pressure mold 33. A positioning strip 36 is fixedly connected to one end of the telescopic rod 37. A positioning groove 35 is provided on one side of the forming lower mold 24. The outer side of the positioning strip 36 fits into the positioning groove 35. A compression spring 38 is sleeved on the outer side of the telescopic rod 37. The compression spring 38 is disposed between the upper pressure mold 33 and the positioning strip 36.

[0025] After the transparent plate is heated, the upper die 33 is moved by the operation of the hydraulic cylinder 32. The upper die 33 slides outside the second guide rod 34 and is fixed to make linear motion. During the movement of the upper die 33, the positioning strip 36 first contacts and inserts into the positioning groove 35. The telescopic rod 37 retracts and the compression spring 38 is compressed. The upper die 33 moves to extrude and preform the transparent plate placed on the second guide rod 34. This facilitates the positioning of the extrusion between the upper die 33 and the lower die 24 and prevents displacement from affecting the preforming effect of the transparent plate.

[0026] The method of use and working principle of this device: First, the transparent plate is placed on the lower forming mold 24. The electric push rod 21 drives the moving plate 22 to move, which in turn drives the connecting rod 26 and the infrared heater 27 to move. During the movement of the infrared heater 27, the first heat insulation cover 23 slides outside the second heat insulation cover 28, keeping the cavity between the first heat insulation cover 23 and the second heat insulation cover 28 isolated from the outside. By adjusting the position of the infrared heater 27, the distance between the infrared heater 27 and the transparent plate is adjusted to heat the transparent plate. Then, the hydraulic cylinder 32 drives the upper pressing mold 33 to move. The positioning strip 36 contacts and inserts into the positioning groove 35. The telescopic rod 37 retracts, the compression spring 38 compresses, and the upper pressing mold 33 moves to extrude and pre-form the transparent plate placed on the second guide rod 34.
