Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to an automatic screw machine. Background Art

[0002] Screws are one of the essential parts in the assembly process of mechanical equipment, electronic equipment, etc. A mechanical equipment or electronic equipment may have dozens or even hundreds of screws that need to be tightened. The traditional method of tightening screws is to manually tighten the screws on the products to be assembled. In order to reduce the labor intensity of manual labor and improve production efficiency, automatic screw driving devices have appeared on the market. However, during the process of screwing, this screw driving device needs to move to the position of the feeder to take the screws. Its screw locking efficiency is low and its versatility is poor. In addition, the existing screw driving machine is difficult to flexibly adjust the screw driving according to the height of the workpiece and the position of the screw hole, and its adaptability is poor.

[0003] In order to solve the deficiencies in the prior art, people have conducted long-term explorations and proposed a variety of solutions. For example, a Chinese patent document discloses an automatic screw-driving device [CN201911369474.2], which includes a feeding mechanism, a screw locking mechanism, and a suction nozzle for sucking screws. The feeding mechanism includes a feeding assembly, a blowing assembly, and a conveying member, and the conveying member is provided with a channel for conveying screws. The feeding assembly is provided with a discharge port, one end of the conveying member is provided at the discharge port, the channel of the conveying member is connected to the feeding assembly, and the blowing assembly is used to blow air into the channel to blow out the screws in the feeding assembly. After the screws are blown out, the suction nozzle sucks the screws at the feeding port, and locks the screws on the product to be assembled through the screw locking mechanism. The screws in the channel can be quickly blown out by the blowing assembly, so that the screw-driving device does not need to run to the feeding assembly to take the screws, thereby improving the efficiency of screw locking.

[0004] The above solution solves the problem of low efficiency of screw driving in the prior art to a certain extent, but the solution still has many shortcomings, such as: flexible adjustment of screw driving according to the height of the workpiece and the position of the screw hole, and poor adaptability.
