When screws at different screw hole positions of a product are locked through the electric screwdriver, rotation adjustment of the angle of the cylindrical block is achieved through rotation of the motor A, meanwhile, the angle position sensor B moves along with the cylindrical block to detect the angle of the adjusted position, and the motor A drives the cylindrical block to rotate to the needed inclination angle position; therefore, the electric screwdriver in the mounting frame is adjusted to a corresponding inclination angle position to lock a screw of a product, and the inclination angle of the electric screwdriver can be adjusted according to different inclination angles of screw hole positions in the product. Therefore, the locking of the screws on the screw hole positions with various inclination angles can be completed at one time.

Description

Technical Field

[0002] During the assembly process of electronic products, chips often need to be connected to other devices with screws as fasteners. Therefore, during the assembly process of these products, picking up chips and screws and screwing them have become the most basic operations. In the traditional assembly process, manual methods are used to complete the picking up and screwing of chips and screws. This primary working method is inefficient and the product quality cannot be guaranteed. With the development of science and technology, electric screwdrivers have emerged, making batch and mechanized screwing work possible, and electric screwdrivers have been used on a large scale. However, electric screwdrivers still need to pick up screws manually, which restricts the speed of screwing, especially when facing screws with smaller diameters. The electric screwdriver cannot be manually operated to complete the tightening, and the screw locking will cause damage to the product surface.

[0003] To this end, a screw driving assembly of a multi-station composite chip locking machine with the announcement number "CN202411793U" includes a cylinder, an electric screwdriver, a slider, a support plate, a support column, a servo motor, and a lead screw. The cylinder provides power for the electric screwdriver, the servo motor drives the electric screwdriver to move along the lead screw, and the support plate and support column play a supporting role. It can be used in the assembly process of electrical products, children's toys, and electronic products.

[0004] However, for the screw driving assembly of the above-mentioned multi-station composite locking chip machine, although the cylinder, electric screwdriver and slider can realize automatic screw locking of the product and improve the production efficiency, there are still the following obvious defects during use: the above-mentioned large screw driving assembly can only lock the screws on the vertical plane of the electric screwdriver. Due to the shape of the product and the different angles of locking the screws in the set threaded holes, the screw driving assembly cannot complete the problem of screw locking of screw holes with different angles.

The angular rotation of the cylindrical block 7 causes the mounting frame 6 to rotate accordingly, and the electric screwdriver 24 adjusts the inclination angle. At the same time, the angle position sensor B25 is used to sense and limit the rotation position of the cylindrical block 7, so that the electric screwdriver 24 can be accurately adjusted to the position of screw holes at different angles for driving screws, thereby achieving locking of screws driven into screw holes at various inclination angles of the product. Subsequently, the push block 27 is pushed to move by the cylinder 26 and drives the vertical guide block 28 to slide vertically on the vertical guide rod 23 in a directional manner, which is beneficial for the electric screwdriver 24 to drive screws of various depths into screw holes of different depths of the product.
