Description

Technical Field

[0001] The utility model relates to the field of loudspeaker assembly, in particular to a screw locking device for loudspeaker production. Background Art

[0002] In the manufacturing industry of loudspeakers, the tightening of traditional screws is mainly completed by hand. Manual screw tightening mainly includes two methods: pure manual tightening and tightening with an electric screwdriver or a pneumatic screwdriver. The latter generates rotational power through an electric or pneumatic method to replace the frequent manual tightening action, which reduces the working intensity of screw locking to a certain extent. However, since manually placing the screw and aligning the screw head still require a large amount of working time and energy, the overall efficiency improvement is still limited.

A loudspeaker fixture is arranged on the cross plate. A two-axis cross slide that can slide in the up-down direction and the left-right direction is also arranged on the operation platform. A connecting rod mounting base is arranged at the left end of the horizontal guide rail of the two-axis cross slide. A connecting rod is rotatably connected to the connecting rod mounting base. The connecting rod is driven by a driving motor to rotate along the axial direction of the mounting base. A vertically downward screw locking mechanism is arranged on the connecting rod. The screw locking mechanism is located above the loudspeaker fixture; the screw locking device for loudspeaker production further includes a screw feeding system. The screw feeding system is connected to the screw locking mechanism through a pipeline for conveying screws to the screw locking mechanism; the screw locking device for loudspeaker production further includes a control system. The control system is used to control the front-rear sliding of the one-dimensional double-rail slide, the up-down sliding and the horizontal sliding of the two-dimensional cross slide, the rotation of the connecting rod, the screw feeding of the screw feeding system, and the tightening of the screw by the screw locking mechanism.

[0007] Further, the speaker fixture includes a speaker base, and positioning posts are symmetrically arranged around the speaker base. A fixing block is hinged to the upper end of the positioning post, and the fixing block can rotate along the hinge axis. During use, place the speaker on the speaker base, and then rotate the fixing block to press the fixing block against the speaker, thereby fixing the speaker.

[0008] Further, there are two speaker fixtures, which are symmetrically arranged on the cross plate.

[0009] Further, the screw locking mechanism is an electric screwdriver.
