Description

Technical Field

[0001] This application relates to the field of automated equipment, and more particularly to a device for coating bullets. Background Technology

[0002] A bullet is a weapon fired from a firearm; in war, it is one of the simplest tools for killing the enemy, a product of physics, chemistry, materials science, aerodynamics, and technology. It is both a product of civilization and a weapon that can destroy it.

[0003] A conventional bullet consists of four parts: the projectile (bullet), the cartridge case, the propellant, and the primer. The projectile is used to penetrate the target by flying at high speed; the cartridge case connects the projectile and protects the propellant and seals the propellant gases; the propellant gives the projectile a high initial velocity through combustion; the primer consists of a ignition port, an anvil, and firing agent, and its function is to generate a flame upon firing, quickly and reliably igniting the propellant. During firing, the firing agent is ignited by the impact of the firing pin and the anvil, and the flame ignites the propellant through the ignition port.

[0004] When fired, the firing pin ignites the primer, which rapidly burns and ignites the propellant inside the cartridge case. The propellant undergoes a momentary combustion, generating high temperature and pressure, which forces the projectile (projectile) out of the cartridge case. Under the pressure generated by the propellant, the projectile moves forward, is squeezed by the rifling, and rotates before finally being ejected from the chamber.

[0005] However, conventional bullets need to meet strict quality requirements during the manufacturing process. Among them, the assembly and sealing between the bullet and the cartridge case is particularly important, as it will directly affect the quality of the bullet and its effective storage period.

[0006] The original process challenges were as follows: The outer coating (sealant) is transparent. The original manual process involved applying the coating using a syringe or spray valve, and then using the human eye to identify whether it was applied by reflecting light from multiple angles. While this was functionally feasible, the amount of coating needed was too small, which could lead to needle blockage and the leakage of uncoated products during actual production. Furthermore, due to the special nature of bullet products, fluorescent components could not be added during the process, and even if a CCD was added at the back end, it would not be able to identify them. This made it difficult to identify the coating through automatic detection, which was not conducive to automated production. Summary of the Invention

[0007] The purpose of this application is to design a gun bullet external coating device that can improve the sealing performance of the coating position on the workpiece to be coated.

[0008] To achieve the above objectives, this application provides the following technical solution:

[0009] A bullet coating device, comprising:

[0010] The main body of the equipment includes a support plate for holding the workpiece to be coated with adhesive;

[0011] A glue-containing tank is provided on the main body of the equipment, forming an upward-opening cavity for containing glue and paint;

[0012] The adhesive application claw is movably connected to the main body of the equipment. The adhesive application claw has an adhesive application head. The adhesive application head includes a notch section, an arc-shaped notch is formed on the notch section, and an adhesive receiving groove is formed in the arc-shaped notch.

[0013] The adhesive application claw has a first state in which the adhesive application head descends into the adhesive pool and the arc-shaped notch is submerged in the adhesive in the adhesive pool.

[0014] The adhesive application claw has a second state in which at least a portion of the adhesive application head rises above the horizontal plane of the adhesive in the adhesive pool, wherein the arc-shaped notch is located above the horizontal plane of the adhesive and the arc-shaped notch carries the workpiece to be coated.

[0015] The drive mechanism drives the adhesive-applying claw to rise or fall.

[0016] Furthermore, the adhesive application claw is L-shaped in general, and the adhesive application head is formed by extending upward from one end of the adhesive application claw.

[0017] Furthermore, auxiliary sections are formed on both sides of the notch section of the glue applicator, and a glue filling groove is formed on each of the auxiliary sections. The glue filling groove is connected to the glue receiving groove, and the auxiliary section does not contact the workpiece to be glued.

[0018] Furthermore, the adhesive application claw is located below the support plate, and a through hole is formed on the support plate corresponding to the position of the adhesive application head of the adhesive application claw. When the adhesive application claw is in the second state, the adhesive application head is inserted into the through hole from bottom to top and protrudes from the top of the through hole.

[0019] Furthermore, the support plate forms a positioning structure for the workpiece to be coated with adhesive at a position adjacent to the through hole.

[0020] Furthermore, it includes: a rotating rod located above the adhesive tank, with both ends rotatably connected to the main body of the equipment, and the driving mechanism drives the rotating rod to rotate;

[0021] A claw fixing component is used to fix the adhesive application claw to the rotating rod, and the adhesive application claw is formed as a cantilever extending from the rotating rod.

[0022] Furthermore, the claw fixing member includes a first fixing block, a second fixing block, and a movable block;

[0023] The movable block is mounted on the rotating rod and can rotate about the rotating rod as a pivot, and the glue-applying claw is fixed to the movable block;

[0024] The first fixing block is fixed to the rotating rod and cannot rotate relative to the rotating rod;

[0025] The second fixing block is fixed to or integral with the first fixing block, and the second fixing block abuts against the movable block to limit the excessive rotation of the rotating rod.

[0026] Furthermore, each end of the movable block along the axial direction of the rotating rod is provided with a first fixing block, and the second fixing block is fixed to the two first fixing blocks respectively by bolts.

[0027] Furthermore, a compression spring is embedded between the second fixed block and the movable block.

[0028] Furthermore, the drive mechanism includes:

[0029] A linear drive component, wherein the linear drive component is a cylinder or a linear motor;

[0030] The rack and pinion assembly is driven by the linear drive assembly;

The connecting gear drives the rotating rod to rotate together, and the rotating rod drives the first fixed block and the second fixed block to rotate together. The second fixed block pushes the movable block to swing, thereby realizing the raising or lowering of the glue-applying claw.

[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0043] Please refer to Figures 1 to 8 The image shows a bullet coating device 100 disclosed in this application, which is mainly used to apply adhesive to specific locations on a workpiece 200 (such as a semi-finished bullet). The bullet coating device 100 mainly includes a device body 1, an adhesive reservoir 2 disposed on the device body 1, a rotating rod 5 rotatably coupled to the device body 1 and located above the adhesive reservoir 2, a claw fixing member 6 fixed to the rotating rod 5, an adhesive application functional claw 3 rotatably coupled to the rotating rod 5 and cooperating with the claw fixing member 6, and a drive mechanism 4 for driving the rotating rod 5 to rotate.

[0044] The main body 1 of the device primarily serves as a frame and support, and is the main part of the bullet coating device 100 of this application. The adhesive reservoir 2 is box-shaped with an upward opening, and forms an adhesive cavity 20 with an upward opening for accommodating adhesive (such as waterproof sealant). The rotating rod 5 is a long, cylindrical rod located directly above the adhesive reservoir 2, and its two ends are rotatably connected to the main body 1 of the device.

[0045] Please refer to Figures 3 to 7 As shown, the adhesive application claw 3 is generally L-shaped, including a main body (not labeled) and an adhesive application head 30 extending upward from one end of the main body. The adhesive application head 30 is plate-shaped, including a notched section 311 located in the middle and two auxiliary sections 312 located on both sides of the notched section 311. The upper edge of the notched section 311 forms an arc-shaped notch 301, which matches the outer peripheral surface of the workpiece 200 to be adhesiveed and is mainly used to support the workpiece 200 to be adhesiveed. An adhesive receiving groove 3111 is recessed in the arc-shaped notch 301. A straight adhesive filling groove 3121 is recessed on the upper surface of each of the auxiliary sections 312, and the straight adhesive filling groove 3121 communicates with the adhesive receiving groove 3111. It should be noted that, in this application, the preferred embodiment of the straight adhesive filling groove 3121 is a straight groove extending in the horizontal direction; of course, it can also be designed as a straight groove that is slightly inclined towards the arc-shaped notch 301, that is, it forms a small angle with the horizontal direction.

[0046] Please refer to Figures 3 to 5 As shown, the claw fixing member 6 includes a movable block 63, two first fixing blocks 61 that clamp the movable block 63 within the rotating rod 5 along the axial direction, and a second fixing block 62. The movable block 63 passes through the rotating rod 5 and is rotatable about the rotating rod 5. The adhesive-applying claw 3 is fixed to the movable block 63 and forms a cantilever extending from the movable block 63 (or, as can be described, the adhesive-applying claw 3 is formed as a cantilever extending from the rotating rod 5). The two first fixing blocks 61 pass through the rotating rod 5 and clamp the movable block 63 within it. The two first fixing blocks 61 are fixedly disposed with the rotating rod 5, meaning that the first fixing blocks 61 cannot rotate relative to the rotating rod 5. The second fixing blocks 62 are correspondingly locked onto the two first fixing blocks 61, and the second fixing blocks 62 abut against the end of the movable block 63 away from the adhesive-applying claw 3 in the circumferential direction of rotation, thereby limiting excessive rotation of the rotating rod 5. Of course, in other embodiments, the second fixing block 62 and the two first fixing blocks 61 may also be designed as a single piece.

[0047] Please refer to Figures 2 to 5As shown, the main body 1 of the device includes a support plate 11 for supporting the workpiece 200 to be coated with adhesive. The support plate 11 is located directly above the adhesive reservoir 2. The adhesive application claw 3 is located below the support plate 11. A through hole 110 is formed on the support plate 11 corresponding to the position of the adhesive application head 30 of the adhesive application claw 3. When the rotating rod 5 rotates and drives the adhesive application claw 3 to swing, the adhesive application head 30 is inserted into the through hole 110 from bottom to top and protrudes from above the through hole 110. The support plate 11 has a workpiece positioning structure 111 near the through hole 110, which can be an inwardly recessed groove structure, used to position the workpiece 200 to be coated with adhesive and prevent the workpiece 200 to be coated from rolling.

[0048] Please refer to Figures 4 to 6 As shown, the drive mechanism 4 includes a linear drive component 41, a rack component 42, and a connecting gear 43. The linear drive component 41 can be a cylinder or a linear motor. In one embodiment, the linear drive component 41 is assembled and fixed to the device body 1. The connecting gear 43 is integrally mounted on or sleeved on the rotating rod 5. The rack component 42 is slidably connected to the device body 1 via a slide rail component 421. One end of the rack component 42 is integrally mounted on or fixed to the linear drive component 41; the other end of the rack component 42 meshes with the connecting gear 43.

[0049] Please refer to Figure 5 and combined Figure 4 As shown, a rotation limiting block 422 is integrally formed or fixedly provided at one end of the rotating rod 5 adjacent to the connecting gear 43. The rotation limiting block 422 rotates synchronously with the rotating rod 5. A stop block 423 is integrally formed or fixedly provided on the main body of the equipment adjacent to the rotation limiting block 422. When the rotation limiting block 422 rotates synchronously with the rotating rod 5 at a certain angle, the stop block 423 touches the stop block 423 to achieve rotation stop (at this time, the glue applicator 30 is in the highest position).

[0050] The linear drive component 41 drives the rotating rod 5 to rotate. Specifically, the linear motion generated by the linear drive component 41 is transmitted through the rack component 42 and drives the connecting gear 43 to rotate. The connecting gear 43 drives the rotating rod 5 to rotate together. The rotating rod 5 drives the first fixed block 61 and the second fixed block 62 to rotate together. The second fixed block 62 pushes the movable block 63 to swing, thereby realizing the raising or lowering of the glue-applying claw 3.

[0051] The adhesive application claw 3 has a first state in which the adhesive application head 30 descends into the adhesive reservoir 2 and the arc-shaped notch 301 is submerged in the adhesive paint (not shown) in the adhesive reservoir 2, so that the straight adhesive filling groove 3121 and the adhesive reservoir 3111 are filled with adhesive paint (not shown).

[0052] The adhesive application claw 3 also has a second state, in which at least a portion of the adhesive application head 30 rises above the horizontal surface of the adhesive in the adhesive pool 2 (specifically, after the adhesive application claw 3 swings, the adhesive application head 30 is inserted into the through hole 110 from bottom to top and protrudes from above the through hole 110). The arc-shaped notch 301 is located above the horizontal surface of the adhesive. Since the adhesive has a certain viscosity, the straight glue filling groove 3121 and the adhesive pool 3111 are coated with adhesive. The adhesive pool 3111 is placed against the underside of the workpiece 200 to be coated, which is placed in the through hole 110 of the support plate 11. Since the design of the arc-shaped notch 301 can better wrap around the lower part of the outer circumference of the workpiece 200 to be coated, the adhesive can be applied and penetrated into the gap of the workpiece 200 to be coated more quickly and accurately. In this process, the design can also be improved to make the workpiece 200 to be coated rotate, so that the time for the adhesive to be applied and penetrated is shorter. In addition, during the application and penetration process, the linear glue-replenishing groove 3121 can replenish the glue in the glue-retaining groove 3111.

[0053] In a preferred embodiment, a compression spring 7 is embedded between the second fixed block 62 and the movable block 63, which allows the adhesive applicator 30 to adhere better upwards to the workpiece 200 to be coated. This avoids incomplete adhesive application due to various tolerances.

[0054] Please refer to Figures 1 to 5 As shown, the gun and ammunition coating device 100 of this application is also provided with a glue replenishing tank 101. When the glue in the glue tank 2 is lower than the set amount, the glue replenishing tank 101 adds glue to the glue tank 2.

[0055] The bullet coating device 100 of this invention enables automatic glue application to specific locations on the workpiece 200 to be coated (such as the seam between the bullet tip and cartridge case of a semi-finished bullet). It offers advantages such as high production efficiency, high yield, and good equipment stability.
