Description

Technical Field

[0001] This utility model relates to the field of trace exploration technology, and in particular to an automatic marking device for firearms. Background Technology

[0002] Shell casings are often left at the scene of some shootings. Analyzing these casings can quickly identify the gun owner. For firearms like handguns and rifles, the serial number is usually recorded before issuance to the owner. A unique mark is then machined onto the firing pin, and this mark is linked to the serial number, which in turn is linked to the owner's identification information. However, this machining method is inefficient, requires removing the firing pin from the gun, is cumbersome, and is prone to confusion with the serial number. This mismatch between the marking on the firing pin and the serial number hinders the tracing of the firearm's origin. Utility Model Content

[0005] A clamping and positioning mechanism that can move horizontally is used to clamp and position a firearm with its muzzle pointing upwards.

[0006] A marking mechanism, located above the clamping and positioning mechanism, has a laser generator capable of generating laser light for laser marking on the firing pin inside the firearm;

[0007] A side scanning mechanism is provided on one side of the clamping and positioning mechanism. The side scanning mechanism has a horizontally fixed camera for scanning the gun serial number on the gun body. The laser mark corresponds to the gun serial number.

[0008] A visual recording mechanism is located above the clamping and positioning mechanism and is arranged in parallel with the marking mechanism. The visual recording mechanism has a vertically fixed camera for recognizing and recording the marks on the striking pin.

[0010] Preferably, the clamping and positioning mechanism includes two upright plates, a clamping cylinder and a first contouring mold respectively disposed on the two upright plates, and a second contouring mold connected to the output end of the clamping cylinder. The first contouring mold and the second contouring mold are disposed opposite to each other, and the opposite sides of the first contouring mold and the second contouring mold have contouring grooves adapted to the shape of the firearm. The clamping cylinder can control the second contouring mold to move closer to or away from the second contouring mold.

[0011] Preferably, the machine base is provided with a column, and the column is provided with a supplementary light, the light of which can illuminate the firing pin of the firearm.

[0017] In this invention, the firearm is positioned with its muzzle facing upwards and clamped and positioned by a clamping and positioning mechanism. A camera scans the firearm's serial number, and then the clamping and positioning mechanism moves to below the marking mechanism. The marking mechanism emits a laser through a laser generator, which passes through the muzzle and marks a unique laser mark on the firing pin.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] like Figures 1-3 As shown, a preferred embodiment of this utility model proposes an automatic firearm marking device. The device mainly includes a machine base 1, a clamping and positioning mechanism 2, a marking mechanism 3, a side scanning mechanism 4, and a visual recording mechanism 5. The firearm is clamped and fixed by the clamping and positioning mechanism 2, and then the side scanning mechanism 4 scans the firearm's serial number. Next, the marking mechanism 3 passes through the muzzle and applies a laser mark to the firing pin. Finally, the visual recording mechanism 5 records the mark and binds the mark to the firearm's serial number for subsequent tracking.

[0027] like Figure 4 As shown, a transverse movement module 8, a first base 9, a longitudinal movement module 10, and a second base 11 are provided on the machine base 1. The transverse movement module 8 is fixedly mounted on the machine base 1 and is a motor-screw module. Two guide rails are provided on the machine base 1, and the bottom of the first base 9 is slidably connected to the guide rails via a slider. The lead screw in the transverse movement module 8 is driven to the bottom of the first base 9, and the motor controls the rotation of the lead screw, thereby driving the first base 9 to slide.

[0028] The longitudinal movement module 10 is mounted and fixed on the base 9 and is perpendicular to the transverse movement module 8. The longitudinal movement module 10 also uses a motor-screw module, with the motor driving the screw to rotate. Two guide rails are also provided on the base 9, perpendicular to the two guide rails on the machine base 1. The bottom of the base 11 is slidably connected to these two guide rails via a slider. The screw of the longitudinal movement module 10 is drive-connected to the bottom of the base 11, and the motor controls the screw to rotate, thereby driving the base 11 to slide along the guide rails on the base 9.

[0029] The clamping and positioning mechanism 2 is installed and fixed on the base 11, and the position of the clamping and positioning mechanism 2 is adjusted by the horizontal moving module 8 and the vertical moving module 10.

[0030] like Figure 4 As shown, the clamping and positioning mechanism 2 mainly consists of a vertical plate 21, a clamping cylinder 22, a first contouring mold 23, and a second contouring mold 24. Two vertical plates 21 are provided, both vertically fixed. The clamping cylinder 22 is horizontally fixed to one of the vertical plates 21 via a cylinder fixing plate. The second contouring mold 24 is connected to the output end of the clamping cylinder 22. The first contouring mold 23 is located on the opposite side of the second contouring mold 24 and is fixedly installed on the other vertical plate 21.

[0031] Contouring grooves are provided on opposite sides of the first and second contouring molds 23 and 24, the shape of which is adapted to the shape of the firearm. The first and second contouring molds 23 and 24 can be replaced depending on the type of firearm. During clamping, the clamping cylinder 22 controls the second contouring mold 24 to move closer to the first contouring mold 23, clamping and positioning the firearm using the first and second contouring molds 23 and 24. During clamping, the muzzle of the firearm faces upwards to allow for marking of the firing pin.

[0032] like Figure 5 As shown, the side scanning mechanism 4 is located on one side of the clamping and positioning mechanism 2 and is also fixedly mounted on the machine base 1. This side scanning mechanism 4 mainly consists of a stand 41, a mounting base 42, and a camera 43. The stand 41 is vertically fixed on the machine base 1, and the mounting base 42 is mounted on the stand 41. The stand 41 is made of profile material, and the mounting base 42 can be adjusted up and down relative to this profile. The camera 43 is horizontally fixed on the mounting base 42. The gun has a unique serial number on the outside of the firearm, which is bound to the firearm. Before marking, the camera 43 scans the serial number and records it in the system.

[0033] The marking mechanism 3 and the visual recording mechanism 5 are both located above the clamping and positioning mechanism 2.

[0034] like Figure 6 As shown, the marking mechanism 3 mainly consists of a support frame 31, a lifting module 32, a sliding seat 33, and a laser generator 34. The support frame 31 is fixedly mounted on the machine base 1. The lifting module 32 is vertically fixedly mounted on the support frame 31. The sliding seat 33 is mounted on the lifting module 32, and its vertical movement is controlled by the lifting module 32. The lifting module 32 uses a handwheel-screw drive system. The screw is connected to the sliding seat 33; rotating the handwheel rotates the screw, which in turn moves the sliding seat 33 up and down. The laser generator 34 is horizontally fixedly mounted on the sliding seat 33, with its laser emission end pointing vertically downwards.

[0035] refer to Figure 6 At the bottom of the laser generator 34, a connecting base 12 is also installed. A vertical moving module 13 is mounted on the connecting base 12, and a depth measuring mechanism 15 is mounted on the vertical moving module 13. This mechanism is used to measure the distance between the laser generator 34 and the firing pin of the gun below. The vertical moving module 13 uses a motor-screw module. The motor controls the rotation of the screw, thereby driving the depth measuring mechanism 15 to move up and down.

[0036] like Figure 6As shown, the depth measuring mechanism 15 mainly consists of a sliding block 14, a measuring rod 151, a guide rod 152, a connecting plate 153, a sliding rod 154, and a spring 155. One end of the sliding block 14 is slidably connected to the slide rail on the vertical moving module 13 and is also connected to a lead screw drive. The other end of the sliding block 14 is equipped with the measuring rod 151 and the guide rod 152, both of which are slidably connected to the sliding rod via bushings. The upper end of the measuring rod 151 is connected to the upper end of the guide rod 152 via the connecting plate 153, and the measuring rod 151 moves up and down together with the guide rod 152. The other end of the sliding rod 154 is slidably connected to the connecting plate 153, and the spring 155 is sleeved on the sliding rod 154 and connected to the connecting plate 153 and the sliding block 14. The lower end of the sliding rod 154 abuts against the sliding block 14.

[0037] Both the measuring rod 151 and the laser emitting end of the laser generator 34 are located directly above the moving path of the clamping and positioning mechanism 2. The clamping and positioning mechanism 2 is controlled by the lateral moving module 8 to move directly below the measuring rod 151, and the vertical moving module 13 controls the measuring rod 151 to move downward. The measuring rod 151 extends into the muzzle of the firearm and comes into contact with the firing pin, measuring the distance to the firing pin and simultaneously measuring the depth of the barrel. At this time, the spring 155 of the depth measuring mechanism 15 extends and stores force, acting as a buffer to prevent the measuring rod 151 from damaging the firing pin.

[0038] The downward movement of the measuring rod 151 is the required downward movement height of the laser generator 34, so as to ensure that the laser emitted by the laser generator 34 can mark the impact pin.

[0039] After the measuring rod 151 completes its measurement, the clamping and positioning mechanism 2 moves to directly below the laser emitting end of the laser generator 34 under the control of the lateral movement module 8. A unique mark is etched onto the firing pin using the laser. This ensures that every bullet fired by the firearm leaves a mark on the cartridge case, which is linked to the firearm's serial number. By analyzing this mark on the cartridge case, the firearm's serial number can be traced, allowing the identification of the firearm's owner.

[0040] After marking is completed, the clamping and positioning mechanism 2 will move to the direct below the visual recording mechanism 5 under the control of the lateral movement module 8.

[0041] like Figure 3As shown, the visual recording mechanism 5 mainly consists of a mounting plate and a camera 43. The camera 43 is vertically fixed on the mounting plate, which is typically mounted on a frame located on the machine base 1. The camera 43 takes pictures of the firing pin through the gun below, recording the markings on the firing pin. The captured images are uploaded to a host computer, which automatically analyzes and compares the images to determine if the markings on the firing pin are acceptable. If unacceptable, the markings need to be re-marked; if acceptable, the markings are associated with the gun's serial number.

[0042] like Figure 3 As shown, a column 7 is installed on the machine base 1, and a fill light 6 is installed on the top of the column 7. The angle of the fill light 6 is adjustable. When the camera 43 takes a picture of the firing pin, the light from the fill light 6 can illuminate the firing pin of the gun to provide supplementary lighting so that the camera 43 can clearly identify the markings on the firing pin.

[0043] The above technical solution only embodies the preferred technical solution of this utility model. Any changes that may be made by those skilled in the art to certain parts of it embody the principle of this utility model and fall within the protection scope of this utility model.
