Description

Technical Field

[0001] The utility model belongs to the technical field of detection devices, and in particular relates to a clamped glass detection device. Background Art

[0002] Electronic glass generally refers to ultra-thin float glass, which is mainly a liquid crystal film with a switching function, which is laminated between two pieces of glass. By utilizing the characteristics of liquid crystal, the glass can be instantly switched between transparent and opaque by simply controlling the power supply. The detection device is mainly used to sense the measured information, and can transform the sensed information into electrical signals or other required forms of signal output according to a certain rule to meet the requirements of system transmission, processing, storage, display, recording and control. The existing detection device used in the electronic glass industry is a robot carrying the glass from top to bottom to sense the presence or absence of each layer of liquid crystal panel glass in the card clip.

[0003] The Chinese invention patent with publication number CN117518289A, a clamped glass detection device for the electronic glass industry, including a slewing mechanism and a glass detection mechanism, the slewing mechanism includes a rotating cylinder, a rotating shaft is arranged above the rotating cylinder, and a substrate is arranged on the side of the rotating shaft, and the glass detection mechanism includes a photoelectric mounting plate, and the photoelectric mounting plate is arranged on the side of the substrate. The clamped glass detection device for the electronic glass industry makes it more convenient and faster for the manipulator to take and put glass by setting a rotating cylinder and a photoelectric mounting plate, reducing the manipulator to detect the presence of each layer of glass in the clamp, while reducing the time for position determination and the risk of position deviation. The use of a rotating cylinder to achieve steering adjustment also ensures the accuracy and stability of the rotation detection, effectively improving the working rhythm, and the overall device structure is stable and compact, meeting the flexible production requirements, and can greatly improve the production efficiency.

[0004] However, the above device has the following technical problems when actually used:

[0005] 1. The above device fixes the substrate by installing a fixing seat on the substrate, and the fixing seat is fixed to the outside of the rotating shaft by bolts. However, when the substrate needs to be inspected and maintained, it needs to be manually disassembled from the rotating shaft, which will cause wear between the fixing seat and the outer wall of the rotating shaft. The fixing seat will be worn every time it is disassembled and assembled. After multiple disassemblies, the tightness between its inner hole and the outer wall of the rotating shaft is reduced. In addition, due to the lack of a supporting device for the fixing seat on the rotating shaft, the fixing seat cannot be stably locked and fixed to the outside of the rotating shaft, which causes problems such as unstable installation of the substrate and falling.

[0006] Second, the above device can only remove the optoelectronic mounting board from the slot by moving the paddle to drive the limiting column to disengage from the limiting groove provided on the optoelectronic mounting board. However, a plurality of optoelectronic mounting boards are arranged on the substrate at equal intervals along its height. The above method can only disassemble and assemble a single optoelectronic mounting board at a time, and cannot meet the requirements of loading and unloading multiple optoelectronic mounting boards at the same time, thus affecting the actual operation efficiency.

After multiple disassembly and assembly, the fixed seat will be worn, thereby affecting the tightness of the connection between it and the rotating shaft, causing the position of the substrate to fall and change after installation, affecting the actual assembly of the substrate. At the same time, the method of pulling the limiting column out of the limiting groove by turning the paddle in the above device can only be used to disassemble and assemble a single optoelectronic mounting board, and cannot meet the requirements of loading and unloading multiple optoelectronic mounting boards at the same time, affecting the actual operation efficiency.
