Technical Field

[0001] The invention relates to the technical field of photovoltaic glass manufacturing equipment, in particular to a high-precision positioning photovoltaic glass automatic punching machine. Background Art

[0002] Solar photovoltaic glass is a special glass used to cover solar cells, protect them and transmit light. Its main function is to allow as much sunlight as possible to pass through, while protecting the cells from external erosion such as moisture, dust, acid and alkali substances, etc., to ensure that solar cells can stably and efficiently convert solar energy into electrical energy.

[0003] Solar photovoltaic glass is a special glass that can generate electricity using solar radiation by laminating solar cells and has related current extraction devices and cables. With the continuous development of science and technology, people's demand for industrial automation is getting higher and higher, and the requirements for glass processing equipment are also getting higher and higher. Since glass is fragile, drilling holes in glass generally uses diamond or other cutting processes to process and drill holes in the entire piece of glass. Since drilling holes in photovoltaic glass is usually done manually, drilling holes is a key process in the production of photovoltaic glass.

[0004] Traditional drilling methods mainly rely on manual operation or simple mechanical drilling equipment. Manual drilling is not only inefficient, but also difficult to ensure the accuracy and consistency of drilling due to human factors. For example, in terms of hole position accuracy, manual operation may result in deviations of several millimeters or even greater, which is unacceptable for photovoltaic modules with increasingly high requirements. Moreover, manual repeated drilling operations are prone to fatigue, further increasing the risk of unstable product quality and affecting work efficiency. Summary of the invention

A threaded hole is provided on the side wall of the frame away from the motor, and a screw is threadedly connected to the threaded hole. One end of the screw is rotatably connected to a push plate, and a rectangular opening is provided on the side wall of the push plate near the conveyor belt, and the side wall of the push plate near the rectangular opening is rotatably connected to an auxiliary plate through a torsion shaft.

[0007] Preferably, a side wall of the frame close to the motor is respectively fixedly connected with a first limit block and a second limit block, the push rod slides through the side wall of the first limit block, and the moving rod slides through the side wall of the second limit block.

[0008] Preferably, the lever mechanism further comprises, A rotating shaft, a side wall at one end of the rotating shaft is rotatably connected to the side wall of the frame, and the rotating rod is fixedly sleeved on the rotating shaft.

[0009] Preferably, a rectangular groove is formed on a side wall of the L-shaped baffle plate close to the push rod.

[0010] Preferably, the side walls of the first limiting block and the second limiting block are both provided with sliding grooves, and the notches of the sliding grooves are respectively larger than the rod diameters of the push rod and the moving rod.

[0011] Preferably, a sleeve is fixedly connected to a side wall of the push plate close to the screw rod, and the screw rod is rotatably connected to an inner side wall of the sleeve.

[0012] Preferably, the side wall of one end of the auxiliary plate close to the push plate is provided with an inclined surface, and the side wall at the rectangular opening provided in the side wall of the push plate is provided with an inclined surface matching the inclination thereof.

[0013] Preferably, one end of the screw rod away from the push plate is fixedly connected with a handle.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention is provided with components such as a screw, a push plate, an auxiliary plate, a motor, a first roller and a second roller. When it is necessary to punch a hole in the photovoltaic glass, the handle is turned, and the handle drives the screw to rotate, so that the screw pushes the push plate to move. The distance between the push plate and the L-shaped baffle is adjusted according to the size of the photovoltaic glass, so as to facilitate the limiting effect on photovoltaic glasses of different sizes. 2. The present invention starts the motor to drive the half-tooth gear to rotate, and the first roller meshing with the half-tooth gear rotates accordingly, thereby driving the rotation of the conveyor belt. Due to the setting of the half-tooth gear, the movement of the conveyor belt is intermittent, so that the photovoltaic glass on the conveyor belt pauses for a certain period of time, which is convenient for punching holes in it; due to the setting of the auxiliary plate that is rotatably connected to the side wall of the push plate through the torsion shaft, the photovoltaic glass at the end of the conveyor belt can be well guided.

The present invention arranges components such as a motor, a crank, a push rod, a rotating rod, a moving rod, a first limit block and a second limit block. When the motor rotates, it will drive the crank fixedly connected to its output end to rotate, and the push rod rotationally connected to the crank side wall will move up and down in the first limit block. Since the other end of the push rod is rotationally connected to the rotating rod, when the push rod moves, it will push the rotating rod to rotate around the rotating shaft, so that the moving rod rotationally connected to the other end of the rotating rod slides along the sliding groove opened on the side wall of the second limit block, so that the drill bit fixedly connected to the bottom side wall of the moving rod can move toward the direction of the conveyor belt. Since the crank is an intermittent structure, when the conveyor belt stops conveying the photovoltaic glass, it is convenient for the drill bit to drill holes in the photovoltaic glass.
