Today, China is becoming one of the most active regions in the world in the development of machine vision, and its application scope covers industries such as industry, agriculture, medicine, military, and aerospace. In the detection of network transformer modules, if manual detection is used, the detection module is too small, first, the detection efficiency is very low, second, the detection quality is not high, and third, the labor cost is high. Therefore, machine vision is used for detection. In the process of batch repetitive industrial production, the use of machine vision detection methods can greatly improve the efficiency and automation of production. The automatic coder designed in this way can well solve the problem of low efficiency of manual feeding.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] Examples, such as Figure 1 , Figure 2 , Figure 4 and Figure 8 As shown in the figure, the present invention is a network transformer module detection and encoding system based on machine vision, including a module feeding mechanism, a demolding mechanism, a clamping robot 6 and a machine vision detection mechanism; the module feeding mechanism conveys the network transformer module to the demolding mechanism station; the demolding mechanism is a pair of relatively arranged demolding robots 5, and the demolding robot 5 is driven to clamp and demold by a clamping claw cylinder 19 and a wide pneumatic finger cylinder 20; the clamping robot 6 clamps the detection module after demolding to the machine vision detection mechanism for detection, and clamps and classifies the detected detection module for output.

[0035] like Figure 3 As shown in the figure, the module feeding mechanism includes a feeding conveyor belt 1 and a pushing mechanism; the pushing mechanism includes a feeding pushing cylinder 2, a linear guide rail 3 and a slider 4; the feeding conveyor belt 1 is connected to the slider 4, and conveys the network transformer module to the slider 4; the slider 4 is slidably installed on the linear guide rail 3; the slider 4 is pushed by the feeding pushing cylinder 2 to make a linear motion along the linear guide rail 3, and the network transformer module is conveyed to the demolding mechanism station.

[0036] like Figure 7 As shown in , the machine vision detection mechanism is a CCD detection system; the CCD detection system includes a CCD camera 11 and a lower light source 12 arranged relatively up and down; the CCD camera 11 and the lower light source 12 are respectively mounted on a bracket 14 with adjustable height through a cross bar 13, and the distance between the lower light source 12 and the CCD camera 11 and the distance between the CCD camera 11 and the detection module are adjusted to better achieve the detection target. Both the CCD camera 11 and the light source are cantilevered, leaving enough working space for the clamping manipulator 6 and the rotating discharge.

[0037] like Figure 5 As shown in , the mold clamping manipulator 6 is driven to clamp and rotate by the rotating clamping finger cylinder 7; the mold clamping manipulator 6 and the rotating clamping finger cylinder 7 are simultaneously arranged on the rotating unloading mechanism. The rotating unloading mechanism is a rotating swing table cylinder 10.

[0038] like Figure 6 As shown in, it also includes a linear guide slide 8; the clamping robot 6 and the rotating clamping finger cylinder 7 are slidably installed on the linear guide slide 8; the linear guide slide 8 is driven to slide by the linear guide slide cylinder 9; the linear guide slide cylinder 9 is arranged on the rotating discharge mechanism.

[0039] like Figure 1 and Figure 2As shown in , it also includes an automatic encoding disk mechanism; the automatic encoding disk mechanism is arranged within the conveying range of the clamping robot 6; the automatic encoding disk mechanism includes a loading tray 15, a ball screw slide 16 and a pushing finger 17; the loading tray 15 is slidably installed on the ball screw slide 16; a pushing finger 17 is arranged on the side of the loading tray 15; the pushing finger 17 is driven by a pushing cylinder 18.

[0040] Operation process: First, the equipment is powered on, the control system performs an internal reset, and the mode is selected through the manual automatic switch: if the manual mode is selected, the debugging personnel can manually control the equipment; if the automatic mode is selected, the control system waits for the input of the start signal. The manual mode is generally used in the debugging stage, and the equipment is fully automatically controlled when it is working normally. The motor drives the feeding conveyor belt 1 to convey the network transformer module to the slider 4, and the feeding push cylinder 2 moves, driving the slider 4 to push the network transformer module to the demolding mechanism station. The clamping claw cylinder 19 drives the demolding manipulator 5 to clamp the outer molds on both sides of the network transformer module, the clamping mold manipulator 6 clamps the detection module, and the wide pneumatic finger cylinder 20 moves to both sides, driving the clamping claw cylinder 19 to demold the network transformer, and the outer mold is separated from the detection module. After the demolding is completed, the clamping mold manipulator 6 clamps the detection module and retracts it, and flips the detection module 90° counterclockwise. This position is exactly placed between the CCD camera 11 and the lower light source 12, and the light source is turned on for detection. After the inspection is completed, the rotating swing table cylinder 10 rotates 90° counterclockwise. If the inspection fails, the clamping claws on the mold clamping robot 6 are released, and the unqualified product falls into the unqualified product slot directly below the mold clamping robot 6; if the product is qualified, the linear guide slide cylinder 9 extends, and there is a grid slot with the width of the inspection module on the loading tray 15. The mold clamping robot 6 places the qualified inspection module on the loading tray, and the ball screw slide 16 drives the loading tray 15 to move to the left, aligning the qualified inspection module with the pushing finger 17. The pushing cylinder 18 drives the pushing finger to push the product into the grid slot and reset it. The ball screw slide 16 then moves right to the release position, thereby realizing automatic coding.

[0041] The control system is a programmable logic controller, which also includes travel switches, photoelectric switches, Hall elements and laser sensors; the control system controls the action process of each component. When the control signal of each component is fed back to the control system, the control system controls each motor and cylinder through the drive control circuit, relay, solenoid valve, etc.

[0042] The whole device is placed on the workbench, and the workbench is built with aluminum profiles for the bottom plate, which is conducive to reducing the weight of the structure; the Hall element at one end of the feeding conveyor belt 1 detects the position of the feeding push cylinder, so that the cylinder is in place to prevent the pushing network transformer module from deflecting. The rotating swing table cylinder 10 is placed on the base and can be adjusted to different heights. The rotating clamping finger cylinder 7 clamping manipulator 6 can be replaced to adapt to different detection elements, saving space and high efficiency. The claws on the manipulator are covered with soft pads to avoid scratching the product surface, effectively protecting the appearance and product quality of the network transformer.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
