[0051] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0052] Existing glass manufacturers typically use hot air preheating devices, which use forced-air heating to blow hot air onto the glass surface for heat conduction. However, these devices suffer from low heating efficiency and large footprint. Therefore, not only is ample operating space required for the preheating device, but the device itself must also be preheated in advance, increasing space rental costs and time investment.

[0053] Based on this, please refer to Figures 1 to 5 A glass preheating fixture is proposed, comprising a glass support 1 and preheating devices 2 symmetrically arranged on both sides of the glass support 1. The preheating device 2 includes a support frame 21, a triaxial displacement assembly 22 and a heating device 23. The heating device 23 is connected to the support frame 21 through the triaxial displacement assembly 22. The heating device 23 is arranged on the movable part of the triaxial displacement assembly 22, and the heating end of the heating device 23 is arranged opposite to the support surface of the glass support 1.

[0054] Specifically, the heating device 23 of this utility model is preferably an infrared heater.

[0055] Understandably, the glass preheating fixture of this invention utilizes the high efficiency of infrared heating to generate high efficiency in a short time, thereby penetrating and heating the glass, providing structural support for rapid glass preheating. Combined with the triaxial displacement component 22, it can move the heating device 23 relative to the support surface of the glass support 1, thus enabling full-range heating of the glass surface and improving overall preheating efficiency. Compared with traditional glass preheating fixtures, not only is the heating efficiency significantly improved, but it also solves the problem of large space occupation caused by the need for piping. Furthermore, traditional glass preheating fixtures require preheating of the equipment itself before normal production, and adjusting the heating position requires manually bending the universal joint, which is prone to loosening over time and often requires ropes for fixation, posing a significant safety hazard. The glass preheating device 2 of this invention, however, eliminates the need for heating piping, thus completely avoiding these risks.

[0056] In some embodiments, the triaxial displacement assembly 22 includes a lifting drive 221 and a horizontal drive 222; the heating device 23 is connected to the movable part of the lifting drive 221 via the horizontal drive 222; the moving direction of the lifting drive 221 is parallel to the Z-axis direction; the horizontal drive 222 includes a first drive 2221 and a second drive 2222; the first drive 2221 is connected to the movable part of the lifting drive 221; the second drive 2222 is connected to the movable part of the first drive 2221; the heating device 23 is connected to the movable part of the second drive 2222; the movable part of the first drive 2221 is parallel to the Y-axis direction; the movable part of the second drive 2222 is parallel to the X-axis direction. Specifically, the lifting drive 221, the first drive 2221, and the second drive 2222 are any commercially available device capable of driving an object to reciprocate along a straight line, such as a lead screw 4. The design makes specific modifications to the composition structure of the triaxial displacement component 22. Through the combined movement between the lifting drive component 221, the first drive component 2221 and the second drive component 2222, the heating device 23 can be moved to any position of the product to be heated, ensuring that the surface of the product to be heated can be heated evenly.

[0057] In some embodiments, the lifting drive 221, the first drive 2221, and the second drive 2222 each include a handwheel 3 and a lead screw 4; the handwheel 3 and the lead screw 4 are connected in a transmission manner; the movable parts of the lifting drive 221, the first drive 2221, and the second drive 2222 are respectively connected in a transmission manner to the corresponding lead screw 4; a scale 31 is provided on the outer circumference of the handwheel 3; the lifting drive 221, the first drive 2221, and the second drive 2222 are also provided with an indicator 5; the indicator 5 and the scale 31 are arranged opposite to each other. Specifically, the operator can rotate the lead screw 4 by the handwheel 3 to move the movable parts of the corresponding lifting drive 221, the first drive 2221, and the second drive 2222. This design provides a specific three-axis displacement component 22, enabling workers to adjust the position of the heating device 23 according to the actual structure of the product to be heated. With the help of the scale 31 and the indicator 5, the position of the heating device 23 after adjustment can be recorded. This allows for quick and accurate adjustment of the preheating position of the heating device 23 when preheating the same product next time, saving preparation time and improving work efficiency.

[0058] In some embodiments, the lifting drive 221, the first drive 2221, and the second drive 2222 are all further provided with a locking mechanism 6; the locking end of the locking mechanism 6 and the outer circular surface of the corresponding lead screw 4 are arranged opposite to each other; when the locking mechanism 6 and the corresponding lead screw 4 are locked, the locking end of the locking mechanism 6 and the outer circular surface of the corresponding lead screw 4 abut against each other. By providing the locking mechanism 6, the stability of the triaxial displacement assembly 22 during preheating can be improved, and the handwheel 3 can be prevented from driving the lead screw 4 and the heating device 23 to move when subjected to external force, thereby causing the heating position of the heating device 23 to shift, which in turn affects the heating effect of the product to be heated.

[0059] In some embodiments, the heating device 23 includes a linear guide, a slider, and a carbon crystal tube 231; the linear guide is connected to the movable part of the second drive member 2222; the extension direction of the linear guide is parallel to the Y-axis direction; the carbon crystal tube 231 is slidably connected to the linear guide. Specifically, the carbon crystal tube 231 can also be any commercially available device capable of infrared heating after being powered on, such as a carbon fiber tube; and the coiling shape of the carbon crystal tube 231 can be S-shaped, U-shaped, or spirally coiled. This design makes specific improvements to the structural composition of the heating device 23. By setting the linear guide and using the slider to slidably connect the carbon crystal tube 231 to the linear guide, the movement range of the heating device 23 in the Y-axis direction can be increased, thereby ensuring that the glass preheating fixture of this invention can be adapted to products of any size, thus improving the applicability of the glass preheating fixture of this invention; and during heating, only the carbon crystal tube 231 needs to be electrically connected to the external power supply device to provide structural support for the heating device 23 to generate infrared rays.

[0060] In some embodiments, the glass preheating fixture described above further includes a controller; the heating device 23 further includes a temperature sensor 232; the temperature sensor 232 is electrically connected to the carbon crystal tube 231 via the controller; during preheating, the sensing end of the temperature sensor 232 and the heating area projected by the heating device 23 onto the surface of the product are positioned opposite each other; the temperature sensor 232 is hinged to the carbon crystal tube 231; the temperature sensor 232 can rotate relative to the carbon crystal tube 231 around the Y-axis. This design can monitor the temperature of the glass surface in real time during the glass preheating process, so that when the temperature is lower than the set temperature, the heating signal is transmitted to the carbon crystal tube 231 via the controller to reheat to the set temperature, thereby ensuring that the glass is in a constant temperature preheating state and ensuring that the preheating effect meets the design requirements; at the same time, hinged connection of the temperature sensor 232 to the carbon crystal tube 231 can further improve the flexibility of the temperature sensor 232, allowing the operator to adjust the angle of the temperature sensor 232 according to the distance between the carbon crystal tube 231 and the product to be heated, providing structural support for the temperature sensor 232 to always detect the temperature of the heating area projected by the heating device 23 onto the surface of the product.

[0061] In some embodiments, the number of carbon crystal tubes 231 is at least two. This design further optimizes the number of carbon crystal tubes 231, and by increasing the number of carbon crystal tubes 231, the heating range of the heating device 23 can be effectively expanded, thereby saving time during glass preheating.
