[0046] This invention discloses a relay assembly production line, including a base 1 and a rotary transport rail 2 disposed on the base 1. The length direction of the rotary transport rail 2 is consistent with the length direction of the base 1. A plurality of assembly loading seats 21 are fixedly connected to the rotary transport rail 2, and the assembly loading seats 21 are evenly spaced along the circumference of the rotary transport rail 2. An operating table 11 is provided at one end of the base 1. During operation, the operator sits on the operating table 11 and places relay components onto the assembly loading seats 21.

[0047] The assembly loading base 21 includes a mounting base fixing plate 213 and a mounting base placement plate. The assembly loading base 21 is fixed on the rotary transport rail 2 by the mounting base fixing plate 213. A fixing plug 211 is fixedly connected to one end of the mounting base placement plate. The fixing plug 211 is arranged in a vertical direction. A fixing seat 212 is arranged on one side of the fixing plug 211. At least three fixing seats 212 are provided. In this embodiment, the number of fixing seats 212 is set to three. The three fixing seats 212 are arranged at intervals along the length direction of the assembly loading base 21. The three fixing seats 212 are arranged in sequence along the direction away from the fixing plug 211 as a shell fixing seat 2121 for placing the shell, a terminal fixing seat 2122 for placing the terminal assembly, and a spring fixing seat 2123 for the spring. When the operator places the component, he first puts the coil on the fixing plug 211, and then places the corresponding component on the corresponding fixing seat 212 in sequence. The shell opening is placed upward, and the terminal assembly and spring are placed downward, so that the terminal assembly and spring are partially embedded in the fixing seat 212.

[0048] Along the rotating transport rail 2, a spring assembly device 3, a coil assembly device 4, a housing assembly device 5, a position detection device 6, a height detection device 7, and a continuity testing device 8 are sequentially arranged at intervals. The spring assembly device 3 and the continuity testing device 8 are located on opposite sides of the operating platform 11. The spring assembly device 3, the coil assembly device 4, and the housing assembly device 5 constitute an assembly module for assembling relay components. After the relay components placed on the assembly loading seat 21 by the operator are assembled by the assembly module, a finished relay is obtained. The position detection device 6, the height detection device 7, and the continuity testing device 8 constitute a testing module for testing the finished relay.

A cylinder for controlling the coil gripper 44 is also provided on the coil lifting base 43. When the assembly loading base 21 with the relay components with the completed spring assembly passes the coil assembly device 4, the coil gripper 44 extends towards the coil fixing base 212 and clamps the coil component placed on the coil fixing base 212. Then, it moves along the coil assembly frame 41 to above the terminal fixing base 2122, and then descends to assemble the coil onto the terminal assembly, thus completing the second step of the relay assembly process.

[0054] The outer casing assembly device 5 includes an assembly bracket 511 and a pressing bracket 521 respectively disposed on both sides of the assembly loading base 21. Both the assembly bracket 511 and the pressing bracket 521 are fixedly connected to the base 1 and are arranged vertically. A cylinder is fixedly connected to one end of the assembly bracket 511.

Pressing bracket 521, pressing cylinder 522, pressing platform 523, and pressing block 524 constitute pressing structure 52 for pressing. When the assembly mounting seat 21 passes the housing assembly device 5, the terminal gripper 514 grabs the terminal component and rotates 180° under the drive of the flip motor 515, so that the terminal component faces the orientation. Then the terminal gripper 514 moves and puts the terminal component into the housing. After the initial assembly is completed, the pressing structure 52 is used to press it, thereby completing the relay assembly process.

[0061] The implementation principle of this embodiment is as follows: The operator places the four components of the relay onto the corresponding positions of the assembly loading seat 21 at the operating table 11. The assembly loading seat 21 moves circumferentially along the rotary transport rail 2. First, the spring and terminal assembly are assembled at the spring assembly device 3; then, the coil and terminal assembly are assembled at the coil assembly device 4; and finally, the housing and terminal assembly are assembled at the housing assembly device 5, thus initially obtaining a finished relay. After the assembly steps are completed, the assembly loading seat 21, carrying the relay, continues to pass through the position detection device 6, height detection device 7, and continuity testing device 8, thus obtaining the final good relay. When the assembly loading seat 21 carrying the good relay passes through the finished product discharge device 9, the finished product discharge device 9 removes the good relay. Then, the empty assembly loading seat 21 continues to move along the rotary transport rail 2 until it returns to the operating table 11, where the operator repositions the relay components. The solution disclosed in this application uses automated equipment for relay assembly, replacing traditional manual operation, improving production efficiency, and saving labor costs by reducing the number of required operators.

[0062] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
