[0044] Please refer to Figures 1 to 2 This utility model provides a non-metallic thin plate flattening device, including a heating table 1, a temperature control device 2, and a pressure cover 3.
[0045] The heating table 1 has a table surface 101 for supporting the workpiece; the temperature control device 2 is used to heat the heating table 1 and control the temperature of the heating table 1; the pressure cover 3 is used to press the workpiece onto the table surface 101 so that the workpiece fits the table surface 101.
[0046] Specifically, the workpiece is first placed on the table 101, then the pressure cap 3 flattens the workpiece on the table 101. The temperature control device 2 heats the heating table to anneal the non-metallic sheet, thereby eliminating the internal residual stress of the non-metallic sheet. The non-metallic sheet flattening device in this embodiment can effectively eliminate the internal residual stress of the non-metallic sheet, maintain the flatness of the non-metallic sheet for a longer period, and improve the production qualification rate of the non-metallic sheet. It should also be noted that annealing involves slowly heating the non-metallic sheet to a certain temperature and holding it for a period of time, then cooling it at an appropriate rate. The annealing temperature is adjusted accordingly for different non-metallic sheet materials.
[0047] Optionally, the pressure cap 3 includes a pressure plate portion 31 and a handle 32 mounted on the pressure plate portion 31; an annular protective protrusion 33 is provided on the outer periphery of the pressure plate portion 31.
[0048] Specifically, during the annealing process of the non-metallic sheet, the annular protective protrusion 33 surrounds the outer periphery of the non-metallic sheet, preventing it from colliding with other mechanical components. Furthermore, the annular protective protrusion 33 ensures that the non-metallic sheet is positioned more effectively on the table 101, resulting in more uniform heating of the sheet.
[0049] Optionally, such as Figure 3 The pressure cap 3 includes a cover body 301 and a heat-conducting plate 302 installed on one side of the bottom of the cover body 301. The heat-conducting plate 302 includes an upper plate body 321, a lower plate body 322, and a heat-conducting pipe assembly 323, which is arranged in an array between the upper plate body 321 and the lower plate body 322. The upper plate body 321 and the lower plate body 322 are fixedly connected, and the space between the upper plate body 321 and the lower plate body 322 is filled with thermal grease 324. A sealed cavity is formed between the upper plate body 321 and the lower plate body 322, and the heat-conducting pipe assembly 323 passes through the sealed cavity.
[0050] Specifically, the structure of the heat-conducting plate 302 allows for better heat transfer, resulting in a more uniform surface temperature of the non-metallic sheet and improving the annealing effect. It should also be noted that the heat pipe assembly 323 is used to change the temperature of the heat-conducting plate 302, thereby annealing the non-metallic sheet.
[0051] It should also be noted that the heat-conducting plate 302 can heat the non-metallic sheet synchronously with the heating stage 1, and maintain the temperature consistency between the upper and lower parts of the non-metallic sheet, which is beneficial to improving the annealing effect.
[0052] Optionally, the lower plate 322 is a metal plate, and the upper plate 321 is a heat-insulating plate. The lower plate 322 has a better thermal conductivity, which is beneficial to improving temperature uniformity. The upper plate 321 is a heat-insulating plate, which helps to prevent burns to workers.
[0053] Optionally, the non-metallic sheet leveling device further includes a temperature control unit for connecting the heat pipe assembly 323 to supply coolant to the heat pipe assembly 323; the temperature of the coolant flowing into the heat pipes is adjustable. The temperature control unit heats or cools the non-metallic sheet by controlling the temperature of the coolant.
[0054] Optionally, the temperature control device 2 further includes a connecting pipe 21 and a constant temperature heating device 22; the constant temperature heating device 22 is connected to the heating platform 1 through the connecting pipe 21, and a heating chamber 201 is formed in the heating platform 1. The constant temperature heating device 22 is used to input a constant temperature liquid into the heating chamber 201 through the connecting pipe 21. It should be specifically noted that the temperature of the constant temperature liquid output by the constant temperature heating device is different for different stages of annealing.
[0055] Optionally, the temperature control device 2 is a heating wire assembly installed in the heating platform 1.
[0056] Optionally, the temperature range of the countertop 101 is 50°-200°.
[0057] Optionally, such as Figure 4 The pressure cap 3 includes a frame 3001 rotatably connected to the heating table 1 and a pressure plate 3002 slidably mounted on the frame 3001. In this embodiment, the position of the pressure plate 3002 can be changed by rotating the frame 3001, thereby loosening or tightening the non-metallic sheet. Preferably, a sliding column is provided on the frame 3001, the pressure plate 3002 is slidably mounted on the sliding column, and a telescopic device is provided on the frame 3001 for driving the pressure plate 3002 to slide along the sliding column.
[0058] Optionally, the cap 3 is a one-piece structure.
[0059] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
