Description

Intelligent row drilling processing production line

technical field

The invention relates to the technology in the field of sheet metal processing machinery, in particular to an intelligent row drilling processing production line.

Background technique

At present, with the promotion of Industry 4.0, the production mode of furniture factories has also ushered in a change. More and more large furniture factories are using automated production lines. The production of panel furniture is inseparable from drilling equipment, such as mass production. The production line of plate, drilling equipment is indispensable.

In the process of automatic connection production, in order to obtain various production requirements, the plate will undergo a series of processing and manufacturing, such as conveying, polishing, drilling, etc. The conveying and drilling of the plate are usually carried out by conveying tables and drilling equipment. , the drilling equipment drills the plate through the arranged drilling device; but the existing conveying table usually adopts a driving mechanism, and the conveying speed of the front and rear sections of the conveying table is the same; thus, the drilling equipment cannot be well connected , resulting in an increase in the product defect rate;

In addition, traditional in-line drilling equipment has always been a shortcoming of the entire line, and its efficiency is much lower than that of edge banding equipment, which reduces the production capacity of the entire line. The power of the traditional row drill is driven by a cylinder. This driving method has the disadvantages of inaccurate control of the displacement size of the row drill, long adjustment time, and inability to realize the flexible and controllable stroke, which affects the efficiency, and the displacement driving mechanism. The unreasonable structural layout of the drill will affect the layout of the overall structure; in addition, the production line can be continuously processed without interruption, which puts forward higher requirements for the reliability of equipment accuracy. If the drill bit deviates from the target position during the drilling process , it will result in the batch scrapping of the board, and the loss will be very large. The drilling equipment drills the plate through the set drill row device, and the drill row of the drill row device needs to move in translation. For this reason, it is necessary to set the translation drive screw to ensure the translation of the row drill, and the translation drive shaft is used for batch drilling. In the process, although there is an air lock, the angle deviation may still occur due to long-term vibration, but the current drilling device does not have an angle deflection monitoring structure, so it is impossible to dynamically monitor the angle deflection of the drive screw in real time, resulting in possible When the angle of the drive screw is deflected, the plate continues to be processed, resulting in the scrapping of the plate in batches.

In addition, in the process of automatic production line, the plates from the edge banding machine are transferred to the drilling equipment through the conveying table for processing. At this time, there will be a problem. The length and width of the plates flowing through the conveying table cannot be judged. Whether the direction corresponds to the processing direction of the equipment, there will be two consequences. First, it may cause the plate to be punched incorrectly in batches. Second, the plate may not flow through the equipment. In order to reduce the failure rate of automatic connection equipment, it is necessary to check whether the feeding direction of the board is correct before the board enters the equipment. The foreign connection equipment generally adopts laser measurement, but the cost is very high, and it is affected by factors such as floating and sinking. influences.

Therefore, it is necessary to develop a new technology to solve the above problems.
