Dynamic state correcting mechanism of photovoltaic module sealing film/backboard cutting machine

Abstract

The invention provides a dynamic state correcting mechanism of a photovoltaic module sealing film/backboard cutting machine. The dynamic state correcting mechanism of the photovoltaic module sealing film/backboard cutting machine is mainly composed of a servo motor, a precision roller, two bearings, two bearing blocks, two pressure sensors and a rack, wherein the precision roller is mounted on the rack through the bearings and the bearing blocks, the rack is provided with a slot, the bearing blocks are mounted in the slot and can move up and down in the slot, the pressure sensors are mounted in the rack below the bearing blocks, the servo motor is connected with one end of the rack on which the bearing block is mounted, the rack connected with the servo motor is movable, when two pressure sensor have different measurement values, the servo motor acts to adjust the height of one end of the roller so as to enable the pressure at both ends to be the same. The mechanism provided by the invention has simple structure, can achieve real-time dynamic adjustment under the control of program, and is rapid in response and accurate in adjustment.

[0002] At this stage, my country's photovoltaic module production industry has a low level of equipment automation and urgently needs industrial upgrading and transformation. Therefore, a large number of semi-automated and automated photovoltaic equipment have emerged in the photovoltaic equipment R&D and manufacturing industry. Photovoltaic module cutting machine is one of them, but The degree of automation of photovoltaic module cutting machines on the market is uneven. Some equipment can automatically correct deviation, automatic feeding, automatic cutting, and automatic receiving, and some only have one or two functions.

Due to the late start of the domestic photovoltaic equipment manufacturing industry, low investment, and weak technical force, photovoltaic module cutting machine products have complex structures with high precision, and poor precision with simple structures. There are no products with both excellent structure and precision, and the quality is not high. , the workmanship is rough, and the quality of the products produced by these cutting machines is also low

Whether there is deviation correction in the cutting process has an important impact on the cutting accuracy. Without a dynamic deviation correction mechanism, it is difficult to improve the cutting accuracy of the cutting machine.

Most of the existing deviation correction mechanisms are sensed by photoelectric sensors to control the lateral position of the material roll to achieve the purpose of deviation correction, which makes the mechanism complex and controls the lateral position of the material roll. The inertia of the whole mechanism is large and it is difficult to control
