Description

Technical Field

[0001] The utility model belongs to the field of screw machine positioning equipment, in particular to an injection molding positioning structure for a screw machine. Background Art

[0002] A screw machine, also known as an automatic screw locking machine, is an automated device primarily used for the automatic feeding and tightening of screws. It is widely used in the assembly lines of various electronic products, such as automobiles, computers, televisions, air conditioners, mobile phones, printers, circuit boards, batteries, instruments, and other industries that require screwing. Screw machines can significantly improve production efficiency, reduce production costs, and increase reliability. Injection molded parts require screws installed using screw machines during assembly.

[0003] According to Chinese patent application number: 202322269581.6, a product positioning structure for a screw machine is disclosed, including a base, a movable plate and a screw locking machine, a slide groove is provided on the upper end of the base, a slider is fixedly connected to the bottom end of the movable plate, the slider is slidably connected to the slide groove, a handle is fixedly connected to the upper end of the movable plate, and an installation box is fixedly connected to the upper end of the base. A plurality of electric screwdrivers are installed at the inner end of the screw locking machine, a rotating assembly is provided between the movable plate and the electric screwdriver, and a limiting assembly is provided between the base and the movable plate. The tooth plate drives the unloading table on which the product is placed to rotate, and the rotation angle, the number of rotations and the rotation interval time of the unloading table can be controlled by adjusting the rotation frequency of the servo motor. When there are multiple groups of holes on the product, and the number of holes in each group of holes is greater than two, this device can still meet the screw driving needs, and is simple to operate and highly practical.

[0004] The existing technology effectively solves the problem that due to the fixed rotation angle range of the discharge block, the adjustment device can only change the product angle once. For products with more than two holes in each group, it is necessary to frequently adjust the length of the two screws to change the rotation angle of the discharge block, which is inconvenient to use. It has the advantages of being able to meet the needs of screw driving, simple operation and strong practicality. However, this positioning device lacks positioning of the injection molded parts when in use, which makes it easy for the electric screwdriver to deviate when driving screws.
