Description

Detection method for transmission broken shaft of chain type equipment Technical Field The invention belongs to the technical field of photovoltaic cleaning equipment, and particularly relates to a detection method for a transmission broken shaft of chain equipment. Background In the cell link in the photovoltaic field, relate to a kind of chain type cleaning equipment which cleans the single face of the silicon chip, this apparatus adopts the structure of horizontal transport, transmit the silicon chip, the reason for transmitting the silicon chip in this way is that this kind of transmission can carry on the corrasion to the single face of the silicon chip, thus another face which does not need corrasion is protected. Since silicon wafers are transported in a plurality of batch processes, the transport structure system of the device is required to have reliable stability. Along with the continuous upgrading of the photovoltaic cell process, the precision requirement of the photovoltaic equipment is gradually improved, and the stability and the equipment reliability are required to be continuously enhanced. Because the driven shafts of the driving shaft belt are relatively more, the torque ratio of the driving shaft is relatively larger, the problems of breakage and slipping of the main transmission shaft and the problem of breakage of the connecting spacer between the main shafts are caused in the production process, the rollers in the equipment can be stopped, the silicon wafer feeding section is not provided with a signal for reminding, the silicon wafer is continuously put in the equipment, a large number of silicon wafers are all in the equipment, and great loss is caused. Disclosure of Invention Aiming at the defects of the prior art, the technical scheme adopted by the invention for solving the technical problems is that the detection method for the transmission broken shaft of the chain type equipment comprises the following steps: Recording initial data, and controlling the running speed of the whole transmission system by controlling the rotating speed of a servo motor, so as to record and set a torque value in normal running; Monitoring equipment operation, namely monitoring and controlling rotation torque by utilizing a servo motor, wherein once an emergency occurs, the torque of the servo motor can be changed; And thirdly, stopping the operation, wherein an alarm is given, a servo motor reads a torque value of a servo in normal operation, and when the torque changes, the torque value of a main transmission shaft is different from a set value, and the equipment gives an alarm and stops the operation. The transmission structure of the existing chain type cleaning equipment is characterized in that a servo motor drives a whole driving shaft to rotate, and then gears are meshed to drive all driven shafts to rotate, so that silicon wafers paved on the driven shafts are moved forward and transferred (as black blocks in fig. 2 represent silicon wafers), the whole driving shaft is relatively long, and therefore, the whole driving shaft is designed and manufactured in a segmented mode during design and production, and the joint of the main shafts is connected by a spacer bush; the problems of breakage and slipping of the main transmission shaft and breakage of the connecting spacer bush between the main shafts can be caused in the production process, and the rotation of the idler wheels in the equipment can be stopped, so that the torque value of the servo motor is changed, and the alarm is triggered to stop. Further, the normal operation in the first step refers to the situation that after the servo motor is started, the whole driving shaft drives all driven shafts to operate, and the torque value of the main driving shaft is recorded. Further, the emergency in the second step refers to the problem of breakage and slipping of the main transmission shaft and the problem of breakage of the connecting spacer between the main shafts, which all cause the rollers inside the device to stop rotating, so that the torque value changes. Further, when the torque force in the third step changes to stop the transmission, the feeding section also stops feeding.
