A third guide part 45 is arranged between the fifth fixing plate 42 and the second bracket 41, the third guide part 45 is a guide pillar, and the third guide part 45 plays a role in guiding and sliding.
The working principle of the assembly mechanism 2 is that a feeding plate 20 of a feeding mechanism I48 places nuts in order and in a uniform direction into the assembly mechanism 2, after the glue injection mechanism 3 finishes glue injection, a feeding mechanism II 49 sends a product hub 59 with glue injected into the assembly mechanism 2 and is positioned below the feeding plate 20, a cylinder IV 50 works, a fixing plate IV 42 integrally moves downwards, a thimble II 43 arranged on the fixing plate IV 42 integrally moves downwards, a cylinder IV 44 works, the thimble II 43 is driven to be inserted into a through hole II 29 of the feeding plate 20, the nuts in the through hole II 29 are pressed into mounting holes with the glue injected into the hub 59 to finish assembly, the cylinder IV 44 is reset, the cylinder IV 50 is reset, a driving part II 24 works the feeding plate 20 to return to the lower part of a discharging disc 4, a driving part III 40 works a fixing seat 38 to return to the lower part of the glue injection mechanism 3, and the hub 59 which finishes processing is taken out.
In the initial position, the proximity switch 8 is opposite to the detection bracket 7, the vibration plate and the linear feeder convey nuts into the first groove body 5 of the discharge plate 4, the first magnet in the second groove body 6 adsorbs the driving part 16 to drive the discharge plate 4 to rotate, the first groove body 5 without the nuts is aligned with the linear feeder, feeding is repeated until the proximity switch 8 is opposite to the detection bracket 7, the nuts are placed in the first groove body 5, the first air cylinder 18 works, the ejector pin 17 pushes down the nuts downwards through the first groove body 5, the nuts enter the second through hole 29 in the attachment plate 27 through the first through hole 28 in the guide plate 26, the nuts are adsorbed in the second through hole 29 through the magnet in the fourth groove body 30, the second driving part 24 works, the feeding plate 20 is integrally moved into the assembly mechanism, meanwhile, the hub 59 is fixed on the fixing seat 38 through the positioning rod, the fixing seat 38 is positioned in the glue injection mechanism 3, the glue injection opening 36 of the glue injection tube 31 is aligned with the mounting hole of the hub 59, the third air cylinder 34 pushes down the first ejector pin 17, the nuts move the fourth ejector pin 40 to the fifth through the second through hole 28 in the guide plate 26, the fifth air cylinder 43 pushes down the fifth ejector pin 42 to fix the fifth ejector pin 43 in the fifth hole 43, and the fifth ejector pin 43 moves the fourth ejector pin to the fifth ejector pin 43.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the embodiments described above, and it will be apparent to those skilled in the art that various modifications and improvements can be made therein without departing from the scope of the invention.
