The second solenoid valve 342 is connected to the first single-axis cylinder 341 through several pipes. The system controls the flow of air, thereby enabling the suction cup 343 to start and stop, and to move vertically up and down. The vacuum generator 344 is connected to the suction cup 343 through several pipes.

[0075] In this embodiment, the ball screw drive module 441 and the motor screw drive module 442 are highly integrated products that are available on the market.

[0076] Specifically, the ball screw drive module 441 includes a rectangular mounting shell 4411, a screw (not shown), balls (not shown), and a nut (not shown).

The fourth solenoid valve 465 is connected to the second single-axis cylinder 464 through several pipes and is used to control the flow of air or change the direction of the airflow, thereby controlling the vertical movement of the third mounting plate 461C.

[0081] The second pusher 463 is fixedly connected to the third mounting plate 461C; the pneumatic finger 466 is fixedly mounted on the third mounting plate 461C.

[0082] Specifically, the pneumatic finger 466 includes a cylinder, a piston, a transmission mechanism, and a finger (not shown). The piston inside the cylinder moves under the pressure of air. The movement of the piston is converted into the opening and closing action of the finger through the transmission mechanism. The finger is fixedly connected to the gripping plate 467, thereby converting it into the opening and closing action of the gripping plate 467. The fifth solenoid valve 468 is connected to the pneumatic finger 466 through several pipes and is used to control the flow of air or change the direction of the airflow, thereby realizing the opening and closing action and the start and stop of the movement of the gripping plate 467.

When the L-shaped block 141 of the moving block 140 passes the fourth sensor module 470, the sensor will output a signal to the controller 400.

[0085] In this embodiment, both the eighth sensor 471 and the ninth sensor 472 are photoelectric sensors;

[0086] The fourth sensor module 470 also includes an in-situ sensor 473, which is set at the motion origin of the moving block 450;

[0087] Specifically, when the moving block 450 moves back and forth along the third linear guide rail 462, the barb 443A it is provided with will pass through the fourth sensor module 470. The fourth sensor module 470 will output a signal to the controller 600. The controller 600 receives the signal and outputs a command to the servo motor driver 431, thereby changing the action of the servo motor 430.

[0088] Furthermore, in order to detect whether the sorting material table 422 is filled with assembled materials, a tenth sensor 473 and an eleventh sensor 474 are also fixedly installed on the sorting material table 422 and below the sorting material trough 423; in this embodiment, the tenth sensor 473 and the eleventh sensor 474 are both micro-switch mechanical sensors.

[0089] In order to connect and secure the wires and cables in the feeding device, the assembly device also includes a fourth terminal block 480 and a cable chain 490 fixedly mounted on the third mounting base plate 411.

[0090] Furthermore, the present invention also includes a pneumatic distributor 700, which is fixedly mounted on the workbench 600 and is used to distribute compressed air to multiple pneumatic devices, such as several cylinders, vacuum generators, etc.

[0091] Furthermore, this utility model also includes a positioning device 800 disposed at the assembly position, comprising a cylinder fixing plate 810, a second dual-axis cylinder 820, a blocking block 830, and a sixth solenoid valve 840; the cylinder fixing plate 810 is fixedly connected to the transverse support member 112, and the second dual-axis cylinder 820 is fixedly disposed on the cylinder fixing plate 810 with the piston rod facing upward and perpendicular to the conveyor belt; the blocking block 830 is directly connected to the piston rod of the second dual-axis cylinder 820, and the side wall of the blocking block 830 conforms to the shape of the outer wall of the first material; the sixth solenoid valve 840 is connected to the second dual-axis cylinder 820 through several pipes, and is used to control the flow of air or change the direction of the airflow, thereby controlling the blocking block 830 to move up and down in the vertical direction.

[0092] When the switch is pressed, the controller 600 controls the conveying device 100 to start, and at the same time controls the first dual-axis cylinder 230 in the feeding device 200 to work, driving the first pusher 240 through the bottom through hole 221 of the material trough 220 to push out the first material located at the bottom of the material trough 220 and push the first material onto the conveyor belt 140 of the conveying device 100. At this time, the second dual-axis cylinder 820 in the positioning device 800 works at the same time to drive the blocking block 830 to move to the assembly position. When the first sensor 151 detects that the first material has been conveyed to the assembly position, it controls the conveying device 100 to stop working.

[0093] At this time, the assembly device 200 is activated. The stepper motor 320, through a pre-programmed sequence, precisely controls the rotation angle of the rotating arm 333. The stepper motor 320 causes the rotating arm 333 to rotate around the central axis 332. Once the rotating arm 333 reaches directly above the area where the second material is placed, the first single-axis cylinder 341 activates, causing the suction cup 343 to move downwards. When the suction cup 343 reaches the position where the second material is placed, the vacuum generator 344 activates, causing the suction cup 343 to pick up the second material. Subsequently, the first single-axis cylinder 341 activates, driving the suction cup 343 upwards. The motor 320 operates, causing the rotating arm 333 to move directly above the first material. The first single-axis cylinder 341 operates, causing the suction cup 343 to move downwards. When the suction cup 343 reaches the position where the first material is placed, it releases the second material, completing the assembly of the first and second materials. Subsequently, the second dual-axis cylinder 820 in the control positioning device 800 operates, causing the blocking block 830 to leave the assembly position, and the conveying device 100 continues to operate. After the second sensor 152 detects that the assembled material has arrived at the sorting position, the control conveying device 100 stops operating.

[0094] At this time, the sorting device 400 is started, and the servo motor 430 works to move the moving block 450 along with the gripping unit 460 mounted on it along the second linear guide rail 4411A. When the moving block 450 and the gripping unit 460 reach directly above the assembled material, the second single-axis cylinder 464 works to move the pneumatic finger 466 and the gripping plate 467 downward. When the gripping plate 467 is near the assembled material, the pneumatic finger 466 works to clamp the gripping plate 467, thus gripping the assembled material. Then the second single-axis cylinder 464 works to move the pneumatic finger 466 downward. 66 and gripping plate 467 move upward. After the pneumatic fingers 466 and gripping plate 467 return to their original positions, the servo motor 430 works to make the moving block 450 and the gripping unit 460 mounted on it move in the opposite direction. When the moving block 450 and the gripping unit 460 mounted on it reach above the sorting material table 422, the second single-axis cylinder 464 works to make the pneumatic fingers 466 and gripping plate 467 move downward. After the assembled material is placed on the sorting material table 422, the pneumatic fingers 466 work to release the gripping plate 467, thus realizing the sorting of the assembled material.

[0095] Compared with the prior art, the present invention has the following beneficial effects:

[0096] 1) By setting up a belt conveyor and installing the devices involved in each process module on the same side in sequence, this training platform can meet the teaching needs, reduce the volume of the training platform by optimizing the layout of each device, and accommodate more training platforms in the same area of ​​training space, thereby allowing more students to operate at the same time and increasing the "average training hours per student".

[0097] 2) By setting different drive modules in the conveying, feeding, assembly and sorting process, trainees can learn and master the control of variable frequency speed control motors, stepper motors and servo motors at the same time, which improves the learning efficiency of variable frequency speed control system, stepper drive system and servo drive system.

[0098] 3) By setting the drive motors in the conveying, feeding, assembly and sorting processes inside each device module or installing them in a folded manner, the large motors are hidden inside, at the bottom or side of each device on the training platform, further reducing the size of the functional modules and reducing manufacturing and maintenance costs.

[0099] 4) By setting each functional module in the conveying, feeding, assembly, and sorting process to be able to operate independently and be used as a separate functional module for teaching and training, the flexibility and efficiency of training for each functional module are improved.
