Then, when the screwdriver 67 is pressed down, the nut of the screw 13 slides downward along the inclined groove 608 until the screw 13 passes through the blanking groove 603 and the blanking port 60. Finally, the screw 13 is connected to the nut 14 on the switch base to complete the assembly. The assembly accuracy of the screw 13 is high.

[0057] Here’s how it works: First, start several vibrating loading trays 21 to load the shell 1, terminal piece 11, terminal piece 2 12, screw 13 and nut 14 respectively, and load them onto each guide rod. The parts are arranged in order on the guide rod, and then moved to the lifting seat 28 through the shell 1. The cylinder 1 27 is used to control the active plate 25 to slide on the support seat 22, and the driven shaft 24 is located in the Z-shaped groove 26 to slide, thereby controlling the driven shaft 24 to move vertically in the vertical groove 23 to increase the height of the shell 1, and then the shell 1 is translated by the shifting claw 74 to move the shell 1 into the feed rod 29.

[0058] The housing 1 passes through assembly part 1 3, assembly part 2 4, assembly part 3 5 and assembly part 4 6 in sequence, and terminal part 1 11, terminal part 2 12, nut 14 and screw 13 are assembled in sequence. First, the two terminal parts 11 are inserted into the switch housing, and then the two terminal parts 2 12 are press-fitted into the switch housing. After the terminals inside the switch housing are press-fitted, the nut 14 is assembled. Before assembly, the switch housing is located at the rotating table, and the switch housing is rotated by using the rotating table to rotate the switch housing horizontally 180 degrees.

[0059] Then the switch housing is moved to assembly part three 5 and assembly part four 6, and the nut 14 is pressed. Then the screw 13 is stably conveyed to the top of the nut 14, and the screwdriver 67 is moved downward to press the screw 13 onto the nut 14. Then the screwdriver 67 is controlled to rotate by motor two 64, and the screw 13 is rotated to pass through the terminal piece one 11 and threadedly connected with the nut 14 to complete the assembly of the terminal parts of the switch housing. Then the switch housing moves horizontally along the feed rod 29 to discharge the material.
