It centralizes various scattered learning elements to form a system that allows students to participate in design, construction, and debugging, and enables more teachers to participate in research and development, design, and learning.

[0003] In the existing mechanical experimental platform, after students finish making parts and mark them, the products are immediately put into storage for display. Then, after the display on the display rack, the tutor measures each one by one and records the size information. This method consumes a lot of time of the tutor and is prone to measurement errors. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] An intelligent manufacturing machinery experimental platform, as Figures 1 - 4 shown, includes:

[0040] A blanking mechanism 1, which includes a blanking cylinder 5 for guiding the workpiece to fall and a pneumatic push arm 6 located below the blanking cylinder 5 and capable of telescopically pushing the workpiece close to the feeding mechanism 2; a feeding mechanism 2, which includes a belt conveyor 10 located at the end of the stroke of the pneumatic push arm 6 and a calibration detection mechanism for calibrating and measuring the workpiece; a grasping and conveying mechanism, which includes a conveying tray 4 for placing the workpiece and a robotic arm assembly 3 for grasping the workpiece to the conveying tray 4; several material distribution cylinders 19 for collecting and classifying the workpieces are provided below the conveying tray 4, and the calibration detection mechanism includes calibration rods 9, infrared ranging sensors and a marking device 12 capable of marking the workpiece numbers located on both sides of the belt conveyor 10.

[0041] Among them, the belt conveyor 10 is provided with guide plates, and guiding baffles 7 that symmetrically incline and guide the calibration detection mechanism intermediate area are provided at the input end of the calibration detection mechanism. A card slot 11 for blocking and limiting the workpiece is provided at the output end of the guide plate. The guiding baffle 7 guides the workpiece conveyed on the belt conveyor 10 close to the central area, so that the workpiece can be conveyed to the card slot 11 and be blocked and limited accordingly.

[0042] Among them, guiding and calibrating rods 9 and mounting platforms for lifting the coding device 12 are provided on both sides of the guide plate. The calibrating rod 9 is screwed into or out of the mounting platform through a hand crank 8. The coding device 12 can move up and down or left and right on the mounting platform. According to the size of the standard workpiece, the length of the calibrating rod 9 can be adjusted by driving the threaded connection between the hand crank 8 and the mounting platform to facilitate the size measurement by the infrared distance sensor. Students can pre-enter the workpiece identification information, and the coding device 12 can mark and record the workpiece. The infrared distance sensor records the measured size information and the mark in the terminal.

[0043] Among them, the robotic arm assembly 3 includes a rotating head, a pneumatic telescopic arm 13, and a pair of claws 14 hinged to the pneumatic telescopic arm 13. An electric push head 15 is provided at the center of the pneumatic telescopic arm 13. The two ends of the electric push head 15 are respectively hinged to the claws 14. And the pneumatic telescopic arm 13 is provided with an optical sensor that can identify the label. After the optical sensor identifies the mark, it grabs and classifies the workpiece according to the recorded size information.

[0044] Among them, the conveying tray 4 is provided with a number of stacking cylinders 16 for stacking workpieces. A hopper 17 for closing the passage below the stacking cylinder 16 is hinged below each stacking cylinder 16 of the conveying tray 4. The conveying tray 4 is provided with an opening and closing device for driving the hoppers 17 to open and close synchronously. The stacking cylinders 16 are used to stack workpieces of different sizes, which is convenient for teachers to classify and count the products produced by students.

[0045] Such as Figures 5 - 6 , the opening and closing device of the first embodiment includes a number of sliders 21 slidably connected to the conveying tray 4 and a connecting rod 20 installed on the sliders 21 and hinged to the hopper 17. An air-expandable telescopic sleeve 18 is installed between the sliders 21. The air-expandable telescopic sleeve 18 is sleeved on the conveying tray 4, and the conveying tray 4 can drive the air-expandable telescopic sleeve 18 to expand and deform. The conveying tray 4 drives the air-expandable telescopic sleeve 18 to expand or contract through an air pump, driving the sliders 21 to slide up or down, driving the connecting rod 20 to pull the hopper 17 to open and close synchronously.

[0046] Such as Figures 7 - 8 , the opening and closing device of the second embodiment includes a cam member 22 rotatably connected to the conveying tray 4 and a fixed rod 23 installed on the hopper 17. The end of the fixed rod 23 is provided with a roller 24. The cam member 22 is provided with a groove 25 for accommodating the roller 24 to guide the movement of the hopper 17. The conveying tray 4 drives the cam member 22 to rotate through a motor. The trajectory of the groove 25 is continuously spaced and undulating. The trajectory of the groove 25 fitted with the roller 24 connected to the fixed rod 23 of the hopper 17 is the same. The roller 24 drives the fixed rod 23 together with the hopper 17 to roll along the trajectory of the groove 25 of the cam member 22 to realize the synchronous opening and closing of the hopper 17.

[0047] Among them, the conveying tray 4 can drive the stacking cylinder 16 to lift. Lifting the stacking cylinder 16 can enlarge the opening of the passage between the hopper 17 and the conveying tray 4 to facilitate the falling of the workpiece.

[0048] Working process: The completed workpieces are successively placed above the blanking cylinder 5 and fall down to the pneumatic push arm 6 below. The pneumatic push arm 6 works to push the workpieces onto the belt conveyor 10. The workpieces are conveyed by the belt conveyor 10 and approach the input end of the calibration and detection mechanism. Guided by the inclined guiding baffle 7, they lean towards the center of the belt conveyor 10. And as they are conveyed by the belt conveyor 10 past the pre-adjusted calibration rod 9, the infrared distance sensor measures the distance between the workpiece and the calibration rod 9 and outputs and records the dimension information. The workpiece continues to be conveyed to the end of the belt conveyor 10 and is blocked and limited by the card slot 11. The coding device 12 marks the workpiece. At this time, the robotic arm assembly 3 works and approaches the workpiece. The electric push head 15 extends to drive the articulated claw 14 to open. After the workpiece penetrates deeply, the electric push head 15 shortens to pull the claw 14 to close and grab the workpiece. The optical sensor detects the mark and compares it with the recorded dimension information to classify and grab the workpiece and place it in the arranged stacking cylinder 16 for stacking.

[0049] Embodiment 1: When the number of workpieces in the stacking cylinder 16 reaches a certain amount, the air-expansion telescopic sleeve 18 is driven by the air pump of the conveying disc 4 to contract, driving all the sliders 21 on the conveying disc 4 to descend simultaneously. At the same time, the connecting rod 20 pulls the hopper 17 to open, driving the stacking cylinder 16 to lift, so that the channel opening between the hopper 17 and the conveying disc 4 becomes larger, and the workpieces then enter the distribution cylinder 19 one by one for collection and storage.

[0050] Embodiment 2: When the number of workpieces in the stacking cylinder 16 reaches a certain amount, the cam member 22 is driven by the motor of the conveying disc 4 to rotate. The roller 24 rolls along the groove 25 track of the cam member 22, driving the connected fixed rod 23 and the hopper 17 to descend and open synchronously. Driving the stacking cylinder 16 to lift makes the channel opening between the hopper 17 and the conveying disc 4 larger, and the workpieces then enter the distribution cylinder 19 one by one for collection and storage.
