Description

Technical Field

[0001] The utility model relates to the field of photovoltaic material processing, in particular to a glass integrity detection and rear plate dropping device. Background Art

[0002] Photovoltaic glass is one of the important packaging materials for photovoltaic modules. In order to ensure better detection of the integrity of photovoltaic glass and remove waste during the production process, the design of the glass drop device is crucial. However, the traditional photovoltaic glass drop device mainly uses roller conveyor and relies on manual unloading of glass waste, which has low safety and production efficiency.

[0003] CN117602375A discloses a plate dropping device, which is provided with a plate dropping roller and an opening and closing mechanism on a frame. Glass is transported through a roller transmission system. When the plate dropping operation is required, the cylinder on the frame is lifted up to drive the rotating shaft at the end of the roller to rotate, and the plate dropping roller flips inward and downward to realize plate dropping. Although the device can realize automatic plate dropping, when a certain amount of waste is accumulated in the storage container, it will affect the normal flipping and dropping of the plate dropping roller. Utility Model Content

[0004] The utility model aims to provide a glass integrity detection rear plate dropping device.

[0005] When the drop plate device of the utility model is working, the opening and closing mechanism moves above the drop material cavity and has nothing to do with the space of the lower drop material cavity, thereby preventing the situation that the plate cannot be opened and closed due to the accumulation of waste materials, and there is no need to stop the machine.

[0006] In order to achieve the above-mentioned purpose of the utility model, the technical solution of the utility model is: a glass integrity detection rear plate dropping device, including a base, a conveying assembly is provided on the base, the conveying assembly includes a drop section and a transport section, and is characterized in that two annular conveying mechanisms are provided at the drop section, an opening and closing mechanism for bringing the two annular conveying mechanisms closer or apart is provided on the base, the opening and closing mechanism includes a linear guide rail fixed on the base and a cylinder for pushing the two annular conveying mechanisms closer or apart, the drop section is provided with a drop chamber, and a photoelectric sensor for detecting glass integrity is provided at the transport section. Adding an opening and closing mechanism for bringing the two annular conveying mechanisms closer or apart makes the drop process more convenient; adding a linear guide rail and a cylinder makes the operation response of the opening and closing mechanism faster and improves the drop efficiency.

[0007] Furthermore, the base is provided with a screw mechanism for adjusting the distance between the two opening and closing mechanisms, and the linear guide rail is fixed on the screw mechanism. The screw mechanism for adjusting the distance between the opening and closing mechanisms is added so that the drop plate device can adapt to glass of different widths.

[0008] Furthermore, the two annular conveying mechanisms at the blanking section are in an eight-shaped shape, with a small opening near the head of the blanking section and a large opening near the tail of the blanking section. The annular conveying mechanism is at an angle of 0 to 5 degrees with the glass transmission direction, and the annular conveying mechanism is an annular belt conveying mechanism. The opening arrangement of the annular conveying mechanism is increased to improve the stability of glass blanking.

[0009] Furthermore, a material box is provided in the material-dropping cavity, a suction plate is provided in the material-dropping box to separate the material-dropping box from top to bottom into a material-dropping area and a suction area, a plurality of suction holes are provided on the suction plate, and a suction mechanism is provided on one side of the suction area. The suction mechanism is added so that waste residues are sucked into the suction area through the suction holes, thereby preventing small glass from splashing and causing subsequent glass breakage.

[0010] Furthermore, the suction plate is made of stainless steel. Adding a suction plate made of stainless steel allows the wear resistance of stainless steel to be utilized during the waste suction process, enabling long-term stable operation and reducing maintenance costs.

[0011] Furthermore, the material dropping area is provided with a material dropping trough, the bottom of the material dropping trough is provided with a through hole matching the suction hole, the suction area is provided with a suction trough, one end of the suction trough is provided with an opening connected to the suction mechanism, and the ends of the material dropping trough and the suction trough are both provided with handles. Adding handles at the ends of the material dropping trough and the suction trough makes it more convenient for workers to replace components.

[0012] The beneficial effects of the utility model are:

[0013] 1. When the photoelectric sensor in the utility model detects that the glass is not complete, the opening and closing mechanism adjusts the opening of the two annular conveying mechanisms so that the waste glass falls accurately into the drop chamber; by adjusting the screw mechanism for adjusting the distance between the opening and closing mechanisms, the adjustment range of the distance between the opening and closing mechanisms is further increased, which can adapt to glasses of different widths.

[0014] 2. In the utility model, a suction mechanism is provided in the blanking area, which effectively collects waste residues to prevent the accumulation and splashing of waste residues in the production area and affect subsequent glass breakage; handles are provided at the ends of the blanking trough and the suction trough to facilitate workers to replace components.

[0015] 3. The transmission component of the utility model adopts a segmented design, and the control transmission and plate dropping functions are relatively independent, which can more accurately adjust the plate dropping position and speed; the annular conveying mechanism and the glass conveying direction are designed in an eight-shaped shape to improve the stability of glass dropping.
