The components in the drawings are not necessarily to scale, and similar reference numerals are generally used to identify similar components.

The present invention will now be further described with reference to the accompanying drawings and detailed description.

Referring to fig. 1 to 5, the present embodiment provides an assembly mechanism of a shower head, including a mounting frame 10, and a screw assembly and a glass bead feeding assembly disposed on the mounting frame 10, where the screw assembly includes a first elevating driver 21 (specifically, a driving cylinder), a screw assembling machine 22, and a screw guide block 23, the screw guide block 23 has a vertical through hole 231 and an inclined guide hole 232 communicating with the vertical through hole 231, the first elevating driver 21 is connected to the screw assembling machine 22, a rotation shaft of the screw assembling machine 22 is inserted into the vertical through hole 231 of the screw guide block 23, and the inclined guide hole 232 is used for connecting a screw feeding mechanism.

The glass bead feeding assembly comprises a clamping seat and an ejection tube 31, the ejection tube 31 is used for being connected with a glass bead feeding mechanism, the tail end of the ejection tube 31 extends to the position below the screw guide block 23, and the clamping seat corresponds to the tail end of the ejection tube 31 and is used for clamping glass beads ejected by the ejection tube 31.

During operation, the ejection tube 31 ejects glass beads, and the clamping seat clamps and positions the glass beads ejected by the ejection tube 31, so that the glass beads can be accurately pre-fixed on the shower head valve body 1, and pre-assembly is realized; then the screw gets into vertical perforating hole 231 through the slope guiding hole 232 of screw guide block 23 to export by vertical perforating hole 231, can be accurate fall into on shower head valve body 1, realize the preassembly of screw. Finally, the first lifting driver 21 drives the screw assembling machine 22 to move downwards, and a rotating shaft of the screw assembling machine 22 penetrates through the vertical through hole 231 of the screw guide block 23, so that screws can be accurately butted and locked; thereby completing the assembly. The assembly mechanism of the spray header can well realize mechanical assembly when assembling glass beads, the preset positions of the glass beads and the screws are accurate, and the screw assembly machine 22 can also accurately butt the screws and realize locking; the method has the characteristics of high operation efficiency and high qualification rate.

Furthermore, in this embodiment, an abdicating window 11 is formed in the mounting bracket 10, the ejection tube 31 is fixed to the rear end of the mounting bracket 10, and the tail end of the ejection tube 31 passes through the abdicating window 11 and extends to the lower position of the screw guide block 23. So, place the fixed knot who launches pipe 31 in the rear that deviates from the station, save overall arrangement space for the mechanism is more compact.
