Service HotlineScrew, some people call it screw [Screw] (screw), screw (screw rod). In fact, the screw is a general term, and the screw and the screw rod are different from each other. Screws are generally called wood screws to fasten wooden and plastic parts. The screw rod is a machine screw (machine screw), which is the kind of flat head at the front end. The pitch is small and uniform. It is generally used to fasten metal and machine parts. With the development of society, the materials for making screws are also various, and the functions of screws are becoming more and more diverse.
In the prior art, the screw suction device can be implemented in the following two ways. One is to use a magnet to magnetize the electric bit head, and the electric bit head is used to approach the screw, and the screw is stuck by the electric bit head, so that the function of picking up the screw can be realized; The vacuum generator is used to form a negative pressure in the screw guide groove, and the screw is sucked into the tube to realize the screw pickup. The disadvantage of this solution is that in the process of picking up the screws, the grooves of the screws cannot be aligned, which leads to the deviation or leakage of the screws. The disadvantage of this solution is that the screw with an aspect ratio of less than 1.5 is prone to suction and skew, and the stability is not high. It can be seen that the existing technology still needs to be improved and developed.
At present, the industry uses the pure manual installation method to install the elastic cylindrical pin, that is, the staff first holds the tool holder; then, manually puts the elastic cylindrical pin into the elastic cylindrical pin hole of the tool holder; then, use the body to align the tool holder For positioning, use a hammer to knock the elastic cylindrical pin into the tool holder. This installation method requires manual operation throughout the entire process, and the work efficiency is low. Moreover, when the hammer is knocked, the staff needs to use the body to position the tool holder, there is a risk of smashing and injuring people, and there is a potential safety hazard. In addition, hammering will cause deformation of the elastic cylindrical pin, and the qualification rate of assembly is low.
In order to effectively improve the working efficiency of bearing installation when the equipment or device is being installed with flat pads, it is necessary to arrange the positions of the front and back of the flat pad.エ Time-consuming, labor-intensive, low production efficiency, high processing cost defects, at the same time, there is a shortage of unstable product quality, so the development of a flat pad front identification feeding mechanism has become a hot spot of industry research.
At present, with the continuous improvement of microwave plasma chemical vapor deposition technology, researchers hope to obtain more excellent products by increasing the microwave power. During the use of the three screws, it is necessary to continuously adjust the length of the pins extending into the rectangular waveguide to make the reflected power of the system reach the minimum value and improve the stability of the system. Since the length of the three screws extending into the waveguide needs to be continuously adjusted with the change of the input power, and the adjustment state of the three screws cannot be recorded after the adjustment is completed, repeated adjustment is still required in the subsequent work, resulting in a time-consuming adjustment process. long and low work efficiency. Especially under high power conditions, the traditional three-screw dispenser has a high risk of microwave leakage. When manually adjusting, the human body is exposed to microwaves for a long time, which has certain potential safety hazards.
