[0002] Bullets are weapons fired from firearms. They are one of the simplest tools used to kill enemies or destroy supplies during war. The basic structure of a bullet consists of four parts: the projectile, cartridge (casing), propellant, and primer (primer). The lethality of a bullet is mainly determined by its penetration and stopping power. Penetration refers to the ability of a bullet to drill into or penetrate an object, while stopping power refers to the effectiveness of the bullet in making the target immobile after it hits the target.

[0003] The cartridge case is an important component of the bullet. After the cartridge case is produced and processed, it needs to be inspected to ensure that the bullet has qualified quality. The existing inspection methods are mostly manual inspection, which has the problems of low efficiency, high error rate and high labor cost. Moreover, since the cartridge case is cylindrical, it needs to be manually turned over by staff for a comprehensive inspection. Therefore, we need to propose a chain-type inspection device with a flipping function. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-3 , the utility model provides a technical solution:

[0028] A chain 4-type detection device with a flipping function, comprising:

[0029] The main structure includes a bracket 1 and a table 8, the bracket 1 is used to support the table 8, the table 8 is provided with pillars 2 on both sides, and a support plate 3 is provided between the pillars 2 on both sides;

[0030] Conveying mechanism; the conveying mechanism includes two rows of chains 4 and conveying rollers 5. The chains 4 make a circular motion between the two groups of support plates 3. The conveying rollers 5 are rotatably installed between the two groups of chains 4. The chains 4 are driven by a motor 7. The support plates 3 are provided with enclosures 6 on both sides of the chains 4. Sprockets for driving the chains 4 are rotatably installed on the pillars 2 on both sides of the table 8. The two groups of sprockets on the same side are connected together by an axle rod. A motor 7 is installed on one side of the table 8. The output end of the motor 7 is connected to the axle rod on one of the groups of sprockets for transmission.

[0031] Detection mechanism: The detection mechanism includes a first detection camera 9 and a second detection camera 11. Two groups of first detection cameras 9 are provided. The two groups of first detection cameras 9 are respectively installed on one side of the two groups of support plates 3 for detecting the two end faces of the product. The second detection camera 11 is installed just above the table 8 for detecting the surface of the product. The table 8 is provided with a first fixing frame 12 on one side of the two groups of support plates 3. The two groups of first detection cameras 9 are respectively installed on the two groups of first fixing frames 12. The table 8 is provided with a second fixing frame 13, and the second detection camera 11 is installed on the upper end of the second fixing frame 13.

[0032] Flipping structure; the flipping structure includes a rubber strip 18 and a transverse plate 17 for fixing the rubber strip 18, two groups of transverse plates 17 are symmetrically arranged between the two groups of support plates 3, and the transverse plates 17 are located directly below the conveying roller 5, the rubber strip 18 is arranged between the two groups of transverse plates 17, and the rubber strip 18 is in contact with the bottom surface of the conveying roller 5.

[0033] A conveying mechanism including a chain 4 and a conveying roller 5 is provided for conveying cartridge cases, a detection mechanism including a first detection camera 9 and a second detection camera 11 is provided for detecting the end face and surface of the cartridge cases, and a flipping structure including a rubber strip 18 and a cross plate 17 is provided for flipping the cartridge cases during the detection process. In actual use, after the production and processing is completed, the cartridge cases fall onto the conveying roller 5 on the chain 4 through a feeding pipe 20 on one side of the equipment, and the motor 7 works to convey the cartridge cases to the detection mechanism. When the cartridge cases pass through the two groups of first detection cameras 9, since the two groups of first detection cameras 9 are respectively installed on both sides of the table 8, the first detection camera 9 can capture images of both ends of the cartridge cases for detection. Since the second detection camera is located directly above the table 8, the lens of the second detection camera 11 is directly facing the cartridge cases conveyed below, so the second detection camera 11 can capture images of the movement on the surface of the cartridge cases for detection.

[0034] During the inspection process, since the rubber strip 18 is attached to the conveying roller 5 between the chains 4, during the movement of the chain 4, the friction between the rubber strip 18 and the conveying roller 5 causes the conveying roller 5 to rotate, and friction is also generated between the conveying roller 5 and the cartridge case, causing the cartridge case itself to flip over, so that the second inspection camera 11 can perform comprehensive image capture and inspection of the cartridge case surface.

[0035] A side light source 10 is also provided on one side of the first detection camera 9 for providing good lighting conditions when detecting the cartridge case, thereby making the detection image clearer and the detection result more accurate.

[0036] Specifically, the present application generally adopts machine vision technology, and the appearance of the cartridge case is converted into an image signal by the first detection camera 9 and the second detection camera 11 for image capture (the first detection camera 9 and the second detection camera 11 can be set as CMOS or CCD cameras) and transmitted to a computer with an image processing system, and then these signals are processed and analyzed by a dedicated image processing system to detect defects and flaws on the surface of the cartridge case, and the traces on the bottom of the cartridge case, the bottom groove of the cartridge case, and the cylindrical surface of the bullet head can be unfolded and analyzed to quickly and accurately display the characteristics of the traces and their relative positional relationship. The image of the trace can be input into the computer for comparative analysis, so as to more accurately judge the appearance quality of the cartridge case.

[0037] In general, the device has a simple structure and is easy to use. It improves the efficiency of shell detection and reduces the error rate through automated detection. At the same time, during the detection process, the shell can be automatically turned over to conduct a comprehensive detection of the shell surface, avoiding the mixing of defective products and ensuring that the product has qualified quality.

[0038] Furthermore, after the cartridge case is inspected, it is necessary to classify and unload the cartridge case according to the inspection results, so the present application also includes the following designs:

[0039] See also Figure 1-3 , and also includes a material discharge mechanism, which includes three groups of blowing valves 14 and three groups of material discharge pipes 15. The three groups of blowing valves 14 are installed next to the enclosure 6 on one side of the table 8, and the three groups of material discharge pipes 15 are installed next to the enclosure 6 on the other side of the table 8, and the blowing valves 14 and the material discharge pipes 15 correspond to each other. Three groups of third fixing frames 16 are installed on one side of the table 8, and the blowing valves 14 are installed on the third fixing frames 16. Notches 19 corresponding to the three groups of blowing valves 14 and the three groups of material discharge pipes 15 are opened on both groups of enclosures 6.

[0040] By setting multiple groups of air blowing valves 14 and material discharge pipes 15, the air blowing valves 14 and the material discharge pipes 15 correspond to each other and are respectively set on both sides of the equipment, and a corresponding notch 19 is opened on the enclosure 6 on the chain 4. After the shell detection is completed, when the shell passes through the air blowing valve 14, the air blowing valve 14 works to blow the shell to the corresponding material discharge pipe 15.

[0041] Among them, the blowing valve 14 and the unloading pipe 15 can be set to the corresponding positions 1-3 through programming. The computer in the detection mechanism determines and classifies the shells into qualified products, slight defects and defective products according to the detection results. The unloading pipes are set according to the corresponding shell products. For example, qualified products correspond to the No. 1 position, slight defects correspond to the No. 2 position, and defective products correspond to the No. 3 position. After the shell detection is completed, it is transported to the unloading mechanism. According to the judgment result, the corresponding blowing valve 14 works, and the shells are blown down to the corresponding unloading pipe 15 to complete the classification, unloading and collection of the shells.

[0042] Among them, the control method of the present application is to control the computer built-in controller in the detection mechanism. The control circuit of the controller can be realized by simple programming by technical personnel in this field, which is common knowledge in this field, and this application document is mainly used to protect mechanical devices, so this application document no longer explains the control method and circuit connection in detail.

[0043] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
