[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 5In an embodiment of the present invention, a piston resin surface automatic inspection device includes a feeding conveyor frame 2, a drying furnace conveyor belt 1 is rotatably mounted on the top of the feeding conveyor frame 2, a qualified product conveyor belt 7 is provided on one side of the drying furnace conveyor belt 1, and a defective product conveyor belt 8 is provided on the side of the qualified product conveyor belt 7 away from the drying furnace conveyor belt 1, a discharging conveyor frame 4 is spaced apart at one end of the drying furnace conveyor belt 1, a sintering furnace conveyor belt 5 is rotatably mounted on the top of the discharging conveyor frame 4, the conveying direction of the drying furnace conveyor belt 1 is toward the sintering furnace conveyor belt 5, and the conveying directions of the sintering furnace conveyor belt 5, the qualified product conveyor belt 7 and the defective product conveyor belt 8 are all consistent with the direction of the drying furnace conveyor belt 1; in actual production, since the proportion of defective products is much smaller than the proportion of qualified products, the conveying width of the defective product conveyor belt 8 is smaller than the conveying width of qualified products to ensure full utilization of the conveying space;

[0023] On both sides of the inspection box 15, an inspection moving-in mechanism and an inspection moving-out mechanism are fixedly installed. The inspection moving-in mechanism is used to move the piston 3 on the drying furnace conveyor belt 1 into the inspection box 15 for inspection, and the inspection moving-out mechanism is used to move the piston 3 that has completed the inspection out of the inspection box 15. A qualified product transfer mechanism is provided at one end of the qualified product conveyor belt 7 close to the sintering furnace conveyor belt 5;

[0024] The qualified product transfer mechanism includes a transfer guide rail 9, on the inner wall of which a transfer seat 12 is slidably mounted. A lifting cylinder 13 is fixedly mounted on one side of the transfer seat 12. The output end of the lifting cylinder 13 is fixedly connected to a clamping member for clamping the piston 3. The inspection moving-in mechanism and the inspection moving-out mechanism have the same structure as the qualified product transfer mechanism. The clamping members on the inspection moving-in mechanism and the inspection moving-out mechanism are mounted on the side close to each other. This ensures that the movement paths of the two clamping members can pass through the middle of the inspection box 15, thereby achieving the movement of the piston 3 on the support plate 17.

[0025] A detection mechanism is provided between the qualified product conveyor belt 7 and the drying furnace conveyor belt 1. The detection mechanism includes a detection box 15. A mounting plate 16 is fixedly connected to the inner wall of the detection box 15. CCD cameras 10 are fixedly mounted on both sides of the mounting plate 16. By providing the detection mechanism, the CCD camera 10 is used to take pictures of the piston 3, thereby improving the detection speed and detection accuracy. In conjunction with the detection moving-in mechanism and the detection moving-out mechanism, the piston 3 is automatically transferred. The entire detection process does not require manual participation, which reduces labor costs and also avoids the hidden dangers of damage caused by manual operation.

[0026] In order to improve the stability of the position of the piston 3 during detection, a number of limiting grooves are opened in the middle of the mounting plate 16;

[0027] The inner walls of several limit grooves are rotatably connected to supporting plates 17, the bottoms of several supporting plates 17 are fixedly connected to rotating rods, and the middle parts of several rotating rods are fixedly connected to driving gears 18. A rotating mechanism is provided inside the mounting plate 16, and the rotating mechanism includes a movable groove, the inner wall of the movable groove is slidably connected to a driving rack 19, and several driving gears 18 are meshed and connected with one side of the driving rack 19, and one end of the driving rack 19 is fixedly connected to the driving plate 20. A driving cavity is provided below the movable groove, and a driving cylinder is fixedly installed inside the driving cavity. The output end of the driving cylinder is fixedly connected to the driving plate 20. The movement stroke of the driving cylinder meets the requirements, which can drive the driving gear 18 to move so that the supporting plate 17 and the piston 3 rotate 90 degrees, and the several supporting plates 17 are driven to rotate by the rotating mechanism, and then the several pistons 3 are driven to rotate, and the CCD camera 10 is cooperated to take pictures twice to perform a more comprehensive and uniform detection of the piston 3, so as to avoid the detection error caused by the inability to accurately identify the edge part when only one shooting is performed;

[0028] The clamping member includes a docking plate 14, a plurality of docking grooves are provided at the bottom of the docking plate 14, and electric push rods 21 are embedded in the tops of the docking grooves. The output ends of the plurality of electric push rods 21 are fixedly connected to push plates 22. The push plates 22 are pushed down by the electric push rods 21 to realize the automatic unloading operation of the piston 3. The plurality of electric push rods 21 are controlled separately to realize the movement of unqualified products and qualified products respectively.

[0029] A clamping washer 23 is fixedly connected to the middle of the inner wall of each of the docking grooves. The clamping washer 23 is made of a flexible rubber material, and its inner diameter is slightly smaller than the diameter of the piston 3, thereby achieving a tight stop on the piston 3 and improving the stability of the piston 3 during movement;

[0030] Air inlet cavities are formed on both sides of the docking plate 14. Adjustment motors 24 are fixedly mounted at the bottoms of the two air inlet cavities. Wind shields 25 are fixedly connected to the output ends of the two adjustment motors 24. Air inlet pipes are fixedly connected to one side of the two air inlet cavities. Both air inlet pipes are connected to the output ends of external air supply equipment. Several docking slots are connected via air guide cavities. The two docking slots at the ends are connected to the two air inlet cavities via two connecting cavities. Air is supplied to the air inlet cavities by the external air supply equipment and then into the several docking slots to clean accumulated debris and dust. Simultaneously, the airflow from the bottoms of the two air inlet cavities and several docking slots, in conjunction with the transfer guide rails 9, drives the clamping member to move, blowing and cleaning the belt surfaces of each conveyor belt.

[0031] A material receiving mechanism is fixedly installed on one side of the defective product conveyor belt 8, and the material receiving mechanism includes a material receiving guide rail 26. A receiving box 27 is slidably installed on the inner wall of the material receiving guide rail 26. The inner wall of the receiving box 27 is provided with several receiving cavities, and both sides of the inner walls of the several receiving cavities are fixedly connected with guide inclined plates 28, so as to collect defective products and facilitate subsequent centralized processing.

[0032] The working principle of the present invention is as follows: the piston 3 that has completed drying is transported by the drying furnace conveyor belt 1. When the piston 3 is transported to the position where the conveying mechanism is moved in, the transfer guide rail 9 drives the transfer seat 12 to move, thereby driving the clamping piece to move above the drying furnace conveyor belt 1, and aligning the several docking grooves on the docking plate 14 with the piston 3, and then the lifting cylinder 13 is pressed down, so that the several pistons 3 enter the several docking grooves, and then the lifting cylinder 13 is lifted, and the transfer guide rail 9 drives the clamping piece to move above the detection box 15, and makes the several docking grooves correspond to the tops of the several supporting plates 17, and then the several electric push rods 21 are started, driving the push plate 22 to press down, pushing the piston 3 in the docking groove out, making it fall into the supporting plate 17, and then the clamping piece is removed;

[0033] The CCD cameras 10 on both sides take pictures of the pistons 3 and send the data to the external data processing device for processing and analysis. The driving cylinder then drives the driving plate 20 to move and then drives the driving rack 19 and the driving gear 18 to rotate, so that the several supporting plates 17 and the pistons 3 thereon rotate 90 degrees. Then the CCD camera 10 takes pictures again for detection. After the detection is completed, the pistons 3 in the detection box 15 are moved to the top of the qualified product conveyor belt 7 by the removal conveying mechanism. The electric push rod 21 in the corresponding docking groove that has passed the inspection is started to push the qualified pistons 3 out and place them on the qualified product conveyor belt 7. Then the removal conveying mechanism moves the clamping part to the unqualified product conveyor belt 8 here, and the electric push rod 21 pushes out the unqualified pistons 3. The unqualified pistons 3 are conveyed to the receiving box 27 and received by the receiving cavity. After one receiving cavity is full, the receiving guide rail 26 drives the receiving box 27 to move a distance, and the receiving cavity performs the receiving operation.

[0034] After a period of use, air can be supplied to the air inlet cavity through an external air supply device, and then enters several docking grooves through the guidance of the air inlet cavity and the air guide cavity to clean the debris and dust accumulated inside. At the same time, the airflow sent out from the bottom of the two air inlet cavities and the bottom of several docking grooves, in conjunction with the transfer guide rail 9, drives the clamping parts to move, and blows and cleans the belt surface of each conveyor belt; two adjustment motors 24 drive the wind shield 25 to move, and adjust the wind direction to obtain a larger cleaning range.

[0035] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
