The first catching means 620 can move downward to catch the bolts in the bolt rail 610, and then the first catching means 620 rises and moves toward the jig base 210 to bring the bolts into the bolt receiving portions 211, and finally the rotary plate 200 brings the workpiece 800 to move to the next process together with the bolts.
As shown in fig. 1, 2, and 3, on the basis of the above embodiment, the bolt assembly 700 further includes a bolt assembly 700, where the bolt assembly 700 includes a rotary cylinder 710, a finger cylinder 720, and a second grasping device 730, the rotary cylinder 710 is fixed on the fixing base 100, the finger cylinder 720 is rotatably connected to the rotary cylinder 710, the finger cylinder 720 is used to drive the bolt to turn, the second grasping device 730 is movably disposed on the fixing base 100, and the second grasping device 730 is used to drive the bolt to the workpiece 800.
In order to allow the bolt to be smoothly disposed in the bolt receiving portion 211, since the bolt grasping assembly 600 places the screw upward in the bolt receiving portion 211 when grasping the bolt, it is necessary to turn the bolt over so that the screw portion is downward when assembling the bolt.
In order to achieve the above purpose, a rotary cylinder 710 and a finger cylinder 720 are specially provided, the finger cylinder 720 clamps the bolt in the bolt accommodating part 211 and then turns over through the rotary cylinder 710, the second grabbing component is a mechanical grabbing hand which can move along the x, y and z axes, the second grabbing component grabs the bolt on the finger cylinder 720 and then brings the bolt into the bolt hole of the workpiece 800, and therefore the functions of automatic turning, clamping, moving and assembling of the bolt are achieved.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments, or alternatives may be employed, by those skilled in the art, without departing from the spirit or ambit of the invention as defined in the appended claims.
