Students often separate the operation of mechatronics equipment from control programming, failing to integrate control programming with practical training. Consequently, their programming skills are unclear and they lack proficiency, hindering their deep understanding of mechatronics knowledge. Utility Model Content

A metal origin positioning block 63 is provided at the bottom of the turntable 62, and an inductive proximity switch 11 is provided on the corresponding assembly table 1. The turntable 62 is positioned by the cooperation of the inductive proximity switch 11 and the metal origin positioning block 63. A stepper motor drives a turntable 62 to rotate counterclockwise.

The fixed station 61 is a fixed ring.

[0046] The first feeding mechanism 2 includes a first storage cylinder 21, a first feeding device 22, a first conveyor belt 23, and a first handling device 24. The first storage cylinder 21 is used to place the first workpiece 12. The first feeding device 22 feeds the first workpiece 12 from the first storage cylinder 21 into the front end of the first conveyor belt 23. The first conveyor belt 23 drives the first workpiece 12 to move. The first handling device 24 moves the first workpiece 12 to the fixed station 61 of the rotary table 6.

[0047] A first fixed seat 25 is provided on one side of the front end of the first conveyor belt 23. The first storage cylinder 21 is fixed on the first fixed seat 25. The top surface of the first storage cylinder 21 is provided with a first discharge port 26.

[0050] In this embodiment, black and white first workpieces 12 are randomly placed and stacked in the first storage cylinder 21. The first feeding device 22 pushes the bottom layer of first workpieces 12 onto the first conveyor belt 23, while the fiber optic sensor 290 detects the color of the first workpiece 12. If a black first workpiece 12 is assembled, the white first workpiece 12 conveyed by the first sorting pusher cylinder 291 on the first conveyor belt 23 is pushed out of the first conveyor belt 23 into the first receiving bin 292, leaving only the black first workpiece 12 on the first conveyor belt 23. Alternatively, if a white first workpiece 12 is assembled, the black first workpiece 12 conveyed by the first sorting pusher cylinder 291 on the first conveyor belt 23 is pushed out of the first conveyor belt 23 into the first receiving bin 292, leaving only the white first workpiece 12 on the first conveyor belt 23. When the first workpiece 12 moves to the rear end of the first conveyor belt 23, the first handling device 24 uses the first gripper 247 to grab the first workpiece 12 and place it on the initial fixed position 61 of the rotary table 6.

The second conveyor belt 33 drives the second workpiece 13 to move. The second handling device 34 moves the second workpiece 13 to the rotary table 6 and assembles it with the first workpiece 12 at the fixed station 61 to form a finished product.

[0052] A second fixed seat 35 is provided on one side of the front end of the second conveyor belt 33. The second storage cylinder 31 is fixed on the second fixed seat 35.

A second clearance port 38 is provided on the bottom side of the second storage cylinder 31 away from the second conveyor belt 33. The second feeding device 32 is a push rod cylinder. The second feeding device 32 is fixed on the second fixed seat 35. The telescopic end of the second feeding device 32 enters through the second clearance port 38 and pushes the second workpiece 13 in the second storage cylinder 31 from the second discharge port 37 onto the second conveyor belt 33.

[0053] The second conveyor belt 33 is equipped with a second sorting device 39. The second sorting device 39 includes a fiber optic sensor 290 for color recognition, at least two second sorting pusher cylinders 391, and a second receiving bin 392. The fiber optic sensor 290 is located on one side of the second conveyor belt 33 opposite to the second discharge port 36. The second sorting pusher cylinders 391 and the second receiving bin 392 are respectively located on both sides of the second conveyor belt 33. The second sorting pusher cylinders 391 are used to push the second workpiece 13 off the second conveyor belt 33 and into the second receiving bin 392.

The second mounting base 341 is fixed on the assembly table 1, between the second conveyor belt 33 and the rotary table 6. The two second guide columns 343 are horizontally and vertically parallel on the top of the second mounting base 341. The second horizontal cylinder 342 drives the second horizontal slide 344 to slide horizontally on the two second guide columns 343. The second vertical cylinder 345 drives the second vertical slide 346 to move vertically on the second horizontal slide 344. The adsorption device 347 is disposed on the second vertical slide 346. The adsorption device 347 adsorbs the second workpiece 13 by negative pressure.

[0055] In this embodiment, black and white second workpieces 13 are randomly placed and stacked in the second storage cylinder 31. The second feeding device 32 pushes the bottom layer of second workpieces 13 onto the second conveyor belt 33, while the fiber optic sensor 290 detects the color of the second workpiece 13. If a black second workpiece 13 is assembled, the white second workpiece 13 conveyed by the second sorting pusher cylinder 391 on the second conveyor belt 33 is pushed out of the second conveyor belt 33 into the second receiving bin 392, leaving only the black second workpiece 13 on the second conveyor belt 33. Alternatively, if a white second workpiece 13 is assembled, the black second workpiece 13 conveyed by the second sorting pusher cylinder 391 on the second conveyor belt 33 is pushed out of the second conveyor belt 33 into the second receiving bin 392, leaving only the white second workpiece 13 on the second conveyor belt 33. The rotary table 6 rotates the initial station where the first workpiece 12 is mounted to the second feeding mechanism 3. When the second workpiece 13 moves to the rear end of the second conveyor belt 33, the second handling device 34 uses the adsorption device 347 to adsorb the second workpiece 13 and place it into the mounting hole of the first workpiece 12 at the initial fixed station 61. The fiber optic sensor 290 is prior art and will not be described in detail in this embodiment.

[0056] The assembly inspection mechanism 5 includes an assembly mounting base 51 and a height detection cylinder 52. The assembly mounting base 51 is inverted L-shaped. The bottom of the assembly mounting base 51 is fixed on the assembly table 1. The height detection cylinder 52 is fixed on the top of the assembly mounting base 51 and placed above the fixed station 61. The height detection cylinder 52 is used to detect whether the second workpiece 13 and the first workpiece 12 are assembled in place.

[0057] The rotary table 6 rotates the initial fixed station 61 after the first workpiece 12 and the second workpiece 13 are assembled to a position below the height detection cylinder 52. The height detection cylinder 52 detects the height of the top surface of the second workpiece 13. If the height detection cylinder 52 is touched before reaching the predetermined height or is not touched after reaching the predetermined height, the second workpiece 13 and the first workpiece 12 are not assembled properly, and the finished product is a defective product. If the height detection cylinder 52 is touched by the top surface of the second workpiece 13 only after reaching the predetermined height, the finished product is a good product.
