[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] The utility model provides a full-automatic detection device for shrapnel production and manufacturing, which includes a material arrangement structure, a material conveying structure, a detection structure and a screening structure. The material conveying structure includes a support frame 14. Both ends of the support frame 14 are movably connected with conveying rollers. The two conveying rollers are connected by a material conveyor belt 16. One end of the support frame 14 is fixed with a servo motor. The end of the output shaft of the servo motor is fixedly connected with the end of one conveying roller. When the servo motor rotates, the servo motor can drive the connected conveying roller to rotate. When the conveying roller rotates, the conveying roller can drive the material conveyor belt 16 to rotate.

[0023] A partition plate 15 is fixedly connected to the top of the support frame 14. The bottom of the partition plate 15 is in contact with the top of the material conveyor belt 16. And two grooves adapted to the shrapnel 6 are provided at the bottom of the partition plate 15. A detection opening is provided at the top of the groove. When the device is in use, two groups of shrapnel 6 can be transported simultaneously.

[0024] There are two groups of material arrangement structures. The material arrangement structure includes a material tray 4 and a guide rail 12 adapted to the discharge port of the material tray 4. When the device is in use, the staff places the shrapnel 6 to be detected in the material tray 4. The material tray 4 arranges the shrapnel 6. Through the vibration of the material tray 4, the shrapnel 6 lies flat and enters the guide rail 12. One end of the guide rail 12 away from the material tray 4 extends into the inner cavity of the groove. The shrapnel 6 can be moved onto the material conveyor belt 16 under the action of an external force. The material conveyor belt 16 can convey the material.

[0025] Above the end of the guide rail 12 away from the material tray 4, there are a selection needle 13 and a baffle 7. The selection needle 13 is located on the side of the baffle 7 close to the material tray 4. Both the selection needle 13 and the baffle 7 are connected to the guide rail 12 through a lifting and translation structure. The lifting and translation structure is a translation cylinder 11. The end of the output shaft of the translation cylinder 11 is fixedly connected with a cross bar. Both the top of the selection needle 13 and the baffle 7 are fixed with a lifting cylinder 17. The other end of the lifting cylinder 17 is connected to the cross bar. Through the setting of the lifting and translation structure, the telescopic movement of the translation cylinder 11 can change the position of the selection needle 13. The selection needle 13 can push the shrapnel 6 to move, so that the shrapnel 6 is pushed onto the material conveyor belt 16. The telescopic movement of the lifting cylinder 17 can change the position of the baffle 7 or the selection needle 13 fixedly connected thereto.

[0026] Through the above description, it can be known that when the device is in use, the material conveyor belt 16 can transport two groups of shrapnel 6 simultaneously, improving the detection efficiency of the shrapnel 6. And the material arrangement structure can only transport one shrapnel 6 forward each time. After the shrapnel 6 is detected, another shrapnel 6 is transferred onto the material conveyor belt 6, improving the stability of the material conveyor belt 6.

[0027] The detection structure is located above the support frame 14. The detection structure includes two CCD cameras 5 and a processor 1. A CCD camera 5 is arranged above the detection opening. When the shrapnel 6 moves to the lower part of the CCD camera 5, the CCD camera takes a picture of the shrapnel 6 and sends image information to the processor 1. The processor 1 makes a judgment based on the received image information to see if the shrapnel 6 is qualified. The detection structure is located on one side of the support frame 14 close to the guide rail 12, shortening the distance between the loading position and the detection position of the shrapnel 6, reducing the influence of the operation of the material conveyor belt 16 on the position of the shrapnel 6, and thus improving the reliability of the shrapnel 6 detection.

[0028] The screening structure includes a sensor 8 and a gas generating device. The gas outlet port of the gas generating device is provided with two groups of gas pipelines. The gas outlet ends of the gas pipelines face the groove, and a sensor 8 is arranged on the gas pipelines. When the processor 1 determines that the quality of the shrapnel 6 is qualified, the shrapnel 6 continues to move along with the material conveyor belt 16. When the quality of the shrapnel 6 is unqualified, the processor 1 controls the sensor 8 and the gas generating device to work. The gas pipeline connected to the sensor 8 can eject gas, and the gas ejected from the gas pipeline blows away the defective products, realizing the screening of the products. In some embodiments of the present application, the gas generating device can be an air compressor. The gas pipeline connected to the air outlet end of the air compressor can eject compressed air, and the compressed air is sprayed onto the shrapnel 6, which can blow away the shrapnel 6. This device uses the purging method to remove the defective products, reducing the influence on the material conveyor belt 16 when removing the defective products, and the material conveyor belt 16 can remain stable.

[0029] Defective product channels 9 are fixed on both sides of the support frame 14. The inlet ends of the defective product channels 9 are located inside the cavity of the groove. The gas outlet ends of the gas pipelines face the inlet ends of the defective product channels 9. The blown-away shrapnel 6 can be directly blown into the cavity of the defective product channels 9. A defective product box 3 is arranged below the defective product channels 9. The defective products slide down along the defective product channels 9 and can slide into the defective product box 3.

[0030] Exhaust holes are evenly arranged on the outer side wall of the cavity of the defective product channels 9, facilitating the discharge of the excess gas in the defective product channels 9. The defective product channels 9 are arc-shaped structures protruding outwards, facilitating the defective products to slide into the defective product box 3.

[0031] A guide plate 10 is fixedly connected to one end of the support frame 14 far from the material tray 4. A good product box 2 is arranged below the guide plate 10. The guide plate 10 is inclined. The qualified shrapnel 6 can fall onto the guide plate 10 under the conveyance of the material conveyor belt 16. The guide plate 10 guides the shrapnel 6, enabling the qualified shrapnel 6 to enter the good product box 2.

[0032] All the electrical components involved in this application are prior arts. Those skilled in the art are aware of their connection methods. Through those skilled in the art, all the electrical components in this application are connected to their adapted power supplies through wires, and a suitable controller is selected according to the actual situation to meet the control requirements. For the specific connection and control sequence, refer to the following description. The electrical connection is completed in the order of the sequence of work of each electrical component. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and no further description of electrical control will be given.

[0033] In summary, when the fully automatic detection device for manufacturing the elastic piece 6 is in use, the staff places the elastic piece 6 to be detected in the material tray 4. After the vibration of the material tray 4, the elastic piece 6 lies flat and enters the guide rail 12. The baffle 7 blocks the front end of the elastic piece 6. Under the prompt of the detection system, the translation cylinder 11 extends. When the translation cylinder 11 moves, it drives both the baffle 7 and the selection needle 13 to move. The selection needle 13 pushes the elastic piece 6 until the front end of the elastic piece 6 moves onto the material conveyor belt 16. The lifting cylinder 17 connected to the baffle 7 drives the baffle 7 to move upward until the baffle 7 moves above the elastic piece 6 and contacts the material conveyor belt 16. The elastic piece 6 in contact with the material conveyor belt 16 can move along with the material conveyor belt 16. When the elastic piece 6 moves below the CCD camera 5, the CCD camera 5 takes a photo of the elastic piece and uploads the captured image to the processor 1. The processor 1 determines whether the elastic piece is qualified according to the captured image. If the elastic piece is qualified, the elastic piece continues to move along with the material conveyor belt 16 until the elastic piece separates from the material conveyor belt 16, and the elastic piece slides down along the guide plate 10 into the good product box 2. If the elastic piece 6 is unqualified, the processor 1 controls the gas generating device and the inductor 8 to work. The high-pressure gas is ejected from the air outlet pipeline to blow the unqualified elastic piece into the inner cavity of the defective product channel 9, and the defective product slides down along the defective product channel 9 into the defective product box 3, realizing the screening of the elastic piece 6. And after the elastic piece 6 moves to the side of the baffle 7 away from the selection needle 13, the baffle 7 resets. Another lifting cylinder 17 connected to the selection needle 13 drives the selection needle 13 to move upward until the selection needle 13 moves above the elastic piece 6. The translation cylinder 11 contracts, and the translation cylinder 11 drives the baffle 7 and the selection needle 13 to move until the baffle 7 contacts the elastic piece 6 again. At this time, the selection needle 13 moves between two adjacent elastic pieces close to the baffle 7. Another lifting cylinder 17 drives the selection needle 13 to reset. The selection needle 13 is inserted between the two elastic pieces 6 to limit the elastic piece 6 away from the baffle 7. At this time, there is only one elastic piece 6 between the selection needle 13 and the baffle 7, so that the device only conveys one elastic piece 6 forward each time, and the device quantitatively detects the elastic piece 6 to ensure the accuracy of elastic piece detection.
