Technical Field

[0001] This utility model belongs to the technical field of teaching and training devices, and particularly relates to a desktop mechatronics training device. Background Technology

[0002] In the teaching and practice of mechatronics technology, training equipment has always played a crucial role. Learning mechatronics technology requires students to comprehensively master fundamental knowledge in various fields, including machining technology, electrical and electronic technology, testing technology, hydraulics and pneumatics, electrical control technology, automated production line technology, and electromechanical equipment maintenance. Simultaneously, students must possess a series of key abilities such as operating, installing, debugging, and maintaining mechatronics equipment.

[0003] However, current mechatronics training equipment on the market has many drawbacks. On the one hand, these devices are complex and bulky, making it difficult for students to understand and learn the relevant technologies. The complex structure increases the difficulty of learning and hinders students' absorption and mastery of key knowledge points. On the other hand, their large footprint not only occupies a significant amount of space in the training room, making it impossible to place more training equipment in a limited space, but also makes it impossible to support multiple students learning together, greatly limiting the improvement of teaching efficiency and training scale.

[0004] With the rapid development of mechatronics technology, the industry's demand for talent is becoming increasingly urgent, and more stringent requirements are being placed on the integration, flexibility, and functionality of training devices. To adapt to this trend and meet the practical needs of teaching and practice, developing a compact, fully functional, and cost-effective desktop mechatronics training device has become a top priority. This new type of training device can effectively overcome the aforementioned shortcomings of traditional training equipment, providing a more efficient and practical platform for the teaching and practice of mechatronics technology, and powerfully meeting the urgent needs of the new era for cultivating mechatronics professionals.

[0047] In this embodiment, a linear conveying unit is also provided on the workbench to transport the material block 11 detected by the photoelectric switch 12 at the end of the conveyor belt 7 to several storage locations in the automated storage unit. The linear conveying unit is connected and fixed to the workbench 1 via a bottom mounting plate 16, which is fixed to the workbench 1 surface by several bolts. The end face of the bottom mounting plate 16 in the length direction is parallel to the end face of the workbench in the length direction. An aluminum profile base is provided below the horizontal linear module 17, and one end of the base is fixed to the bottom mounting plate 16 by several bolts. The horizontal linear module 17 includes a lead screw and a slide table 171. The lead screw is fixed to the aluminum profile base by several bearings and connecting plates. By rotating the lead screw, the slide table 171 can move horizontally in a straight line along the axis of the lead screw. The vertical linear module 23 is fixed to the slide table 171 via an L-shaped connector and can move with the slide table 171. The slide table 171 is fixed to the cable chain fixing component 19 by screws on one side. The cable chain fixing component 19 is fixed to the cable chain 18 on one side, allowing the cable chain 18 to move following the slide table 171.

[0050] In this embodiment, the workbench 1 is also equipped with a support 29, which is mainly assembled from aluminum profiles. The lower part of the support has two parallel longitudinal beams with flush end faces, and a transverse beam is provided between the longitudinal beams.

Through the detection of the photoelectric switch 28, the material block 11 held by the gripper of the mechanical finger 27 is aligned with the slot of the storage location 30 in the horizontal direction. The storage location 30 corresponds to the detection position of the photoelectric switch 28 connected to the vertical straight module 23 in the vertical direction. Through the detection of the photoelectric switch 28, the material block 11 held by the gripper of the mechanical finger 27 is aligned with the slot of the storage location 30 in the vertical direction.

[0051] In this embodiment, a servo driver 31 is installed on the workbench 1 to control the servo motor 20, achieving high-precision transmission and positioning of the servo motor. The servo driver 31 is fixed to the workbench 1 via a servo driver mounting plate. A stepper driver 32 is also installed on the workbench 1 to control the stepper motor 25, achieving high-precision transmission and positioning of the stepper motor. In addition, the workbench 1 is also equipped with control components such as a circuit breaker 34, a switching power supply 35, a PLC 36, a switch 37, a solenoid valve group 38, a pressure regulating valve 39, an industrial touch screen 14, and buttons 15. The circuit breaker 34 can protect the overall circuit; the switching power supply 35 mainly provides DC power to the control circuit; the PLC 36 is used to receive signals from various sensors and make feedback control. The switch 37 can be used for communication between the PLC 36 and the industrial touch screen 14; the solenoid valve group 38 and the pressure regulating valve 39 respectively control the pneumatic circuit and regulate the air pressure in the circuit. The industrial touch screen 14 is connected to the workbench 1 via a touch screen bracket 13. The screen of the industrial touch screen 14 forms a 50-degree angle with the plane of the workbench 1 for easy operation. Buttons 15 are also provided on the touch screen bracket 13, including an emergency stop button, a start button, and a stop button, which enable manual operation of the equipment.

[0052] The working principle of this scheme is as follows: Before operation, several material blocks 11 are placed into the storage cylinder 51. The circuit breaker 34 and the start button 15 are closed. The material block 11 at the bottom of the storage cylinder 51 falls into the lower cavity. The proximity switch 6 detects the material block 11, and the pushing mechanism 4 starts to operate. The piston rod of the pushing cylinder retracts, pushing the material block 11 to the conveyor belt 7. When the material block 11 moves to the lower side of the proximity switch 10, the proximity switch 10 detects and sends a signal to the PLC 36. The linear conveying unit starts to operate, causing the mechanical finger 27 to move above the end baffle of the conveyor belt 7. At the same time, the material block 11 is transported to the end baffle along the conveyor belt 7. The photoelectric switch 12 detects that the material block 11 has been transported to the position. The PLC 36 controls the vertical linear module 23 slide to descend, so that the mechanical finger 27 gripper reaches the same height as the material block 11 and controls it to complete the clamping action. The PLC36 controls the linear module slides to move in the reverse direction. When the horizontal linear module 17 or the vertical linear module 23 slides move to the photoelectric switch 28 corresponding to the set storage location 30, the photoelectric switch 28 detects the sensor on the slide, and the corresponding horizontal linear module 17 or vertical linear module 23 slides stop moving in that direction. After both slides 171 and 231 have reached their positions, the rotary cylinder 26 rotates the rotary table 180 degrees, placing the material block 11 clamped by the mechanical finger 27 above the U-shaped slot of the set storage location 30. The mechanical finger 27 releases its gripper, and the material block 11 falls into the slot, completing the transport. The proximity switch 6 continues to detect the material block 11, and the pushing mechanism 6 and the conveyor belt 7 transport the material block 11 to the baffle according to the above process. The photoelectric switch 12 detects the material block 11. After the linear transport unit completes the previous round of operation, it will continue to transport the material block 11 that has been transported to the position according to the above process until all the material blocks 11 have been transported to the corresponding storage location 30.
