[0076] At the same time, the detection rod 582 extends into the terminal hole of the wiring terminal, on the one hand to locate the position of the base so that it is located below the pressure rod 521, and on the other hand to detect the terminal hole of the base.

[0077] The assembly seat 55 is fixed with a symmetrically distributed guide seat 57, and an L-shaped plate 571 is rotatably provided on the guide seat 57. One end of the L-shaped plate 571 is located in the guide seat 57, and the other end is located at the discharge end of the L-shaped groove 56. When the top cover is moved onto the assembly seat 55, the bottom of the top cover is fixed at the ends of the two L-shaped plates 571, and the top cover is supported by the L-shaped plates 571, which then facilitates the movement of the base and the positioning of the top cover. Finally, under the action of the pressure rod 521, the top cover moves down and is assembled with the base. During this process, the L-shaped plate 571 rotates, and the pressure rod 521 is reset after the assembly is completed, and the L-shaped plate 571 automatically resets to the position as shown in the figure. Figure 13 Status in.

[0078] A sink 564 is provided in the L-shaped groove 56. Figures 14-19 As shown, a detection part 7 is fixedly installed in the sink 564, a discharge plate 70 is fixedly provided in the mounting frame 51 and above the L-shaped groove 56, a cylinder thirteen 720 is fixedly provided on the detection part 7, and the output end of the cylinder thirteen 720 is fixedly connected to a U-shaped block 72, and both ends of the U-shaped block 72 support the top cover in the L-shaped groove 56 and support the bottom surface of the top cover.

[0079] A symmetrically distributed clamping rod 73 is rotatably provided in the U-shaped block 72, a clamping claw 732 is fixed at one end of the clamping rod 73, and an inclined plate 75 is fixed at the other end. A guide groove 731 is provided on one side of the clamping rod 73, and a trapezoidal block 76 is fixed in the guide groove 731. A return spring 74 is fixed on the other side of the clamping rod 73, and the return spring 74 is close to the inclined plate 75. A symmetrically distributed column 71 is fixed on the detection part 7, and one side of the column 71 is slidably connected to the side of the clamping rod 73.

[0080] When the clamping rod 73 moves up to disengage from the column 71, the return spring 74 pushes the clamping rod 73 to rotate until the clamping claws 732 contact the inner wall of the top cover, and the internal support of the top cover is fixed by the two clamping claws 732. A side frame 77 is fixed on the column 71, and a horizontal shaft 771 is fixed on the top of the side frame 77. When the lower end of the clamping rod 73 moves to the horizontal shaft 771, the horizontal shaft 771 presses down on the lower end of the clamping rod 73, causing the clamping rod 73 to rotate, so that the two clamping claws 732 are away from the inner wall of the top cover, thereby releasing the fixation of the top cover.

[0081] A rectangular rod 78 is slidably provided on a side frame 77, one end of the rectangular rod 78 is slidably connected to the guide groove 731, and the other end is provided with a V-shaped groove 782, and the V-shaped groove 782 is provided with an inclined groove 781. A vertical rod 791 is slidably provided in the V-shaped groove 782, and a support rod 79 is fixedly provided on the U-shaped block 72. The support rod 79 is used to support one end of the top cover, and one side of the support rod 79 is slidably connected to one end of the vertical rod 791. A support spring 792 is fixedly connected to the vertical rod 791, and the support spring 792 is fixedly connected to the support rod 79 to connect the vertical rod 791. A push rod 793 is fixedly provided on the top of the vertical rod 791, and a slanted sliding surface is provided at the bottom end.

[0082] A visual sensor 66 is also fixed inside the mounting frame 51 and above the L-shaped slot 56. When an error in the top cover feeding is detected, the cylinder thirteen 720 pushes the U-shaped block 72 upward, driving the clamping rod 73 and the vertical rod 791 upward until the bottom end of the clamping rod 73 is separated from the column 71. The reset spring 74 pushes the clamping rod 73 to rotate, allowing the clamping claw 732 to be supported and clamped on the inner wall of the top cover. During this process, one end of the rectangular rod 78 slides along the guide groove 731.

[0083] Then the rectangular rod 78 slides until it just touches the side of the trapezoidal block 76. At this time, the inclined sliding surface is on one side of the inclined groove 781, and the top cover is located at one end of the unloading plate 70. Then the U-shaped block 72 continues to move upward, and the clamping rod 73 contacts the horizontal shaft 771, prompting the clamping rod 73 to rotate to release the fixation of the top cover. At the same time, the rectangular rod 78 slides along the side of the trapezoidal block 76, so that the rectangular rod 78 moves horizontally toward the vertical rod 791. The inclined groove 781 on the rectangular rod 78 cooperates with the inclined sliding surface, and then lifts the vertical rod 791. The vertical rod 791 moves upward and pushes the top cover to tilt through the push rod 793, so that one end of the top cover slides from the support rod 79 to the unloading plate 70, and the top cover that appears in the opposite direction is rejected, thereby improving the quality rate and reducing production costs.

[0084] In this embodiment, each slide adopts the model MXS6-20.

[0085] The contact pieces and pressing pieces are positioned and assembled, and then assembled onto the base. The base is stably transported to the assembly seat 55. The position of the base is positioned and fixed, and the top cover is selected to ensure that the direction of the top cover assembly is correct. The top cover is then mounted on the end of the L-shaped plate 571. After the top cover is transported into place, the cylinder eight 52 can be started to control the pressure rod 521 to move downward, and the top cover and the base are pressed together to form a terminal. Finally, the terminal is driven by the ejector pin three 561 and pushed into the finished product bin 59 to complete the unloading and discharging.
