[0022] Specifically, the voice coil Z-axis electric cylinder 605 can be installed on the mounting base 602 through the mounting bracket 604 and the mounting plate 618. At this time, the voice coil Z-axis electric cylinder 605 is started to move the voice coil electric claw 606 downward, thereby moving the voice coil clamping claw 619 downward, so that the voice coil body 701 can be clamped and fixed.

[0023] Example 2

[0024] See Figure 2 and Figure 3 , and on the basis of Example 1, it is further obtained that the bottom end of the mounting base 602 is fixedly mounted with a horizontal electric cylinder bracket 617, a horizontal electric cylinder 603 is fixedly mounted on the horizontal electric cylinder bracket 617, a connecting bracket 616 is fixedly mounted on the telescopic end of the horizontal electric cylinder 603, a nylon rod pushing Z-direction electric cylinder 615 is fixedly mounted on the connecting bracket 616, a push rod connecting block 621 is fixedly mounted on the telescopic end of the push rod Z-direction electric cylinder 615, and the bottom end of the push rod connecting block 621 is symmetrically fixed. It is connected to a guide rod 608, and the bottom ends of the two guide rods 608 are fixedly connected to a nylon rod push block 607, the bottom end of the mounting base 1 602 is symmetrically slidably installed with a slider 613, the bottom ends of the two sliders 613 are fixedly installed with a mounting base 2 612, the bottom ends of the two mounting base 2 612 are fixedly connected to a connecting plate 611, the bottom end of the connecting plate 611 is fixedly installed with a nylon rod electric claw 609 through a plate, and the bottom end of the nylon rod electric claw 609 is fixedly installed with a nylon rod clamp 620.

[0025] Specifically, by pushing the nylon rod Z-direction electric cylinder 615, the push rod connecting block 621 can be pushed to move, and the guide rod 608 can be pushed to move, thereby pushing the nylon rod push block 607 to move, so that the nylon rod can be pushed into the installation groove, and the horizontal electric cylinder 1 603 can push the connecting bracket 616 to move, thereby pushing the nylon rod Z-direction electric cylinder 615 to move horizontally, so that the distance between the voice coil electric claw 606 and the nylon rod electric claw 609 can be adjusted. The voice coil Z-direction electric cylinder 605 is used to adjust the relative distance between the voice coil electric claw 606 and the nylon rod clamp 620 in the Z direction.

[0026] Example 3

[0027] See Figure 2 and Figure 3 On the basis of the first and second embodiments, it is further obtained that the bottom end of the board is symmetrically fixedly connected with linear bearings 610, and the two linear bearings 610 are both set on the outer wall of the guide rod 608.

[0028] Specifically, the guide column 608 is limited by the linear bearing 610, the voice coil electric claw 606 clamps the gauge body 704 from the inside, and at the same time the nylon rod claw 620 clamps the nylon rod, and the robot body 100 moves to the assembly station (the gauge hole is aligned with the speaker T iron, and the nylon rod is aligned with the nylon rod mounting slot), and then the robot body 100Z descends to the voice coil body 701 to install the T iron, and the nylon rod is now directly above the mounting slot.

[0029] During actual operation, after the robot body 100 moves to the material picking station, the voice coil electric claw 606 clamps the tone gauge from the inside, and at the same time the nylon rod claw 620 clamps the nylon rod, and the robot moves to the assembly station (the tone gauge hole is aligned with the speaker T iron, and the nylon rod is aligned with the nylon rod mounting slot), and then the robot body 100Z descends to the voice coil and the T iron is installed. At this time, the nylon rod is directly above the mounting slot, and then 615 pushes the nylon rod Z-direction electric cylinder to move, driving the 607 nylon rod push block to move downward to push the nylon rod into the mounting slot. The horizontal electric cylinder 603 is used to adjust the distance between the voice coil electric claw 606 and the nylon rod electric claw 609 (for different models of products, the distance between the nylon rod and the voice coil center will be different), and the 605 voice coil Z-direction electric cylinder is used to adjust the relative distance between the voice coil electric claw 606 and the nylon rod claw 620Z (the tone gauge height will be inconsistent for different products).
