[0002] In the processing of glass frames, the positioning of mounting holes is a crucial link. However, traditional positioning methods often rely on workers' experience and manual operations, which is not only inefficient but also prone to errors, affecting product quality and precision.

[0003] For example, the application number CN202121468821.X discloses a side window glass frame mounting hole positioning device, including: a positioning frame, which is respectively aligned with a car window frame with a plurality of mounting holes and a side window glass frame without holes; a plurality of drill sleeve assemblies, each of which is connected to the positioning frame and is used to mark the hole positions of the mounting holes to position the mounting holes of the side window glass frame. The utility model can align the positioning frame with the car window frame, and mark the hole positions of the mounting holes on the car window frame through the drill sleeve assembly, and then align the positioning frame with the side glass frame without holes, so that the mounting holes of the side window glass frame can be positioned according to the hole positions of the mounting holes marked by the drill sleeve assembly, which effectively improves the positioning accuracy and positioning efficiency of the mounting holes of the side window glass frame, thereby improving the replacement efficiency and installation quality of the side-mounted glass.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that although the above equipment can solve the problem of marking the hole positions of the assembly holes on the car window frame by the drill sleeve assembly, and then aligning the positioning frame with the undrilled side glass frame, the mounting holes of the side window glass frame can be positioned according to the hole positions of the assembly holes marked by the drill sleeve assembly, which effectively improves the positioning accuracy and positioning efficiency of the mounting holes of the side window glass frame. However, during use, when the mounting holes of the glass frame are positioned, the mounting holes are positioned and installed by the drill sleeve assembly. When the positioning device is disassembled, since the drill sleeve assembly has many parts, multiple parts need to be disassembled, making this positioning device inconvenient to disassemble, thereby reducing work efficiency.
