It should be noted that, for those skilled in the art, several variations and improvements can be made without departing from the spirit of the present invention. These all fall within the scope of protection of the present invention. In the description of the embodiments of the present invention, it should be noted that the terms "first", "second", etc. in the specification and claims of the present invention are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0041] In order to solve the problem that the efficiency of the existing small-caliber ammunition bullet-binding device cannot meet the actual bullet demand and reduce the product defect rate, refer to Figure 1 , which is a schematic structural diagram of a modular flexible small-caliber ammunition binding device provided by an embodiment of the present invention, comprising a frame 1, a servo power unit 2, a warhead carrier plate 11, a cartridge case carrier plate 9, a ball screw transverse motion unit 10, a ball screw longitudinal motion unit 5, and a press-fitting unit 6, wherein: the frame 1 is used to provide support for the entire device; the servo power unit 2 is used to provide power for the entire device; the warhead carrier plate 11 is used to carry the warhead; the cartridge case carrier plate 9 is used to carry the cartridge case; the ball screw transverse motion unit 10 is used to respectively drive the warhead carrier plate 11 and the cartridge case carrier plate 9 to move along the length direction of the frame 1; the press-fitting unit 6 carries a plurality of press head units 7, and the press-fitting unit 6 is located above the warhead carrier plate 11 and the cartridge case carrier plate 9; the ball screw longitudinal motion unit 5 is used to drive the press-fitting unit 6 to move up and down along the height direction of the frame 1; the press head unit 7 includes a vacuum suction head 7.5, which is used to suck the warhead on the warhead carrier plate 11 and press-fit the cartridge case onto the cartridge case carrier plate 9.

[0042] The embodiment of the present invention uses a single press head for press-fitting, enabling more precise shaping and timely error detection. Each press head is equipped with a vacuum suction head 7.5, which can press-fit the cartridge case with the bullet. Dozens or even hundreds of single-head press-fitting mechanisms can be integrated to press-fit multiple bullets at a time, meeting production line cycle requirements and improving press-fitting efficiency. Furthermore, the press head unit 7 is traceable. If a defective product is found, the specific press head with the problem can be traced, allowing for rapid adjustments and reducing the equipment's defect rate.

[0043] Reference Figure 2-4In some specific embodiments, the pressure head unit 7 is mounted on a pressure plate 7.9. As a single-module press-fitting device, the pressure head unit 7 also includes a pressure rod 7.3 and a pressure sensor 7.2 for transmitting press-fitting pressure information in real time. The pressure sensor 7.2 is provided on the pressure rod 7.3. A vacuum suction head 7.5 is provided at one end of the pressure rod 7.3. The vacuum suction head 7.5 is connected to the pressure rod 7.3 via a connecting pipe assembly 7.4. The connecting pipe assembly 7.4 is also connected to a tracheal connector 7.6 for connecting to the trachea. Specifically, the hollow center of the pressure rod 7.3 connects the pressure sensor 7.2 and the connecting pipe assembly 7.4. The connecting pipe assembly 7.4 is connected to the vacuum suction head 7.5 and is connected to the trachea via the tracheal connector 7.6. Using the pressure sensor 7.2 as a pressure monitor for the entire press-fitting process is conducive to ensuring the controllability and reliability of the entire press-fitting process.

[0044] In other specific embodiments, the pressure head unit 7 further includes a stopper 7.1 and a sleeve 7.7. The stopper 7.1 is connected to one end of the pressure sensor 7.2 to limit and protect the pressure sensor 7.2. The sleeve 7.7 is mounted on the pressure rod 7.3 and located at the other end of the pressure sensor 7.2 to limit the positioning of the pressure sensor 7.2 and provide a sealing effect. Specifically, the pressure rod 7.3 has two cylindrical grooves on its surface, with a boss disposed between the two grooves. The upper cylindrical groove is used to accommodate the sleeve 7.7, and the boss is mounted on the surface of the spring 7.8. The lower cylindrical groove reserves space for the spring 7.8 to expand and contract.

[0045] Preferably, the shape of the vacuum nozzle 7.5 matches the shape of the bullet to facilitate the suction of the bullet 11.1. The vacuum nozzle 7.5 is designed according to the shape of the bullet, and different types of vacuum nozzles 7.5 can be equipped with different bullet types, thereby meeting the flexibility requirements of the production line.

[0046] In the embodiment of the present invention, each bullet has a dedicated pressing head unit 7 for press-fitting. Each pressing head unit 7 is equipped with a pressure sensor 7.2 to monitor the pressure in real time. The bottom of each pressing head unit 7 has a vacuum suction head 7.5 that matches the shape of the bullet, forming a modular single-pressing head press-fitting device. According to the production line rhythm requirements, dozens, hundreds or even more single pressing head units 7 can be integrated; at the same time, different models of vacuum suction heads 7.5 can be equipped to meet the requirements of different types of bullets, thereby achieving a flexible production line production method.

[0047] In some specific embodiments, the shell carrier plate 9 and the bullet carrier plate 11 have the same structure, both including a download plate and an upper loading plate provided above the download plate, the upper loading plate and the download plate are connected by bolts, the download plate plays a supporting role, all mechanisms are provided on the download plate, and the upper loading plate is provided with holes and push rod slots, etc. Figure 5 As shown, Figure 6-8The structural diagram of the cartridge case carrier plate 9 is shown (the upper carrier plate is removed), which includes a carrier plate 9.2, a push rod 9.1, a wedge-shaped pressure block 9.3 and an elastic member 9.5; the push rod 9.1 includes a plurality of cross bars arranged in a row, the same end of the plurality of cross bars is connected to a vertical rod, and the other ends of the plurality of cross bars are respectively abutted on the elastic member 9.5. Preferably, the elastic member 9.5 is a spring, and a spring cover plate 9.6 for covering is further provided above it. A plurality of raised wedge blocks 9.7 are arranged at intervals on each cross bar. The wedge blocks 9.7 are raised blocks with a certain inclination. The wedge blocks 9.7 and the wedge pressure blocks 9.3 are connected by mortise and tenon joints through trapezoidal grooves and trapezoidal raised blocks. The wedge pressure block 9.3 is stuck in the groove of the upper carrier plate. The wedge pressure block 9.3 is used to clamp the cartridge case or bullet. Figure 6-8 The middle wedge-shaped pressure block 9.3 clamps the cartridge case 9.4, and the wedge-shaped pressure block 9.3 is inclined corresponding to the wedge-shaped block 9.7; when the two inclined protrusions move relative to each other, the wedge-shaped block 9.7 pushes the wedge-shaped pressure block 9.3 to move perpendicular to the length of the push rod, that is, converting the longitudinal movement into the transverse movement, thereby clamping or loosening the cartridge case 9.4; one end of the vertical rod of the push rod 9.1 is driven by an external cylinder to move in the push rod groove along the length direction of the cross bar; the push rod 9.1 drives the wedge-shaped pressure block 9.3 to move axially along the cross bar to compress the elastic member 9.5, so that the wedge-shaped pressure block 9.3 relaxes its grip on the cartridge case or bullet, and when the cartridge case or bullet is relaxed, it can be easily sucked away by the vacuum suction head 7.5, as shown in FIG. Figure 6-8 The middle wedge-shaped pressure block 9.3 loosens its grip on the cartridge case 9.4, allowing the cartridge case 9.4 to be easily removed by the vacuum suction head 7.5. Specifically, the push rod 9.1 is pushed along its length, and the protruding wedge-shaped block 9.7 on the push rod 9.1 moves along the length of the push rod 9.1, causing the wedge-shaped pressure block 9.3 to move normal to the push rod 9.1. As the wedge-shaped pressure block 9.3 moves normal to the push rod, the hole between the wedge-shaped pressure block 9.3 and the cartridge case on the upper loading plate expands and contracts, thereby completing the clamping and loosening of the cartridge case 9.4.

[0048] Reference Figure 9In some specific embodiments, the frame 1 is further provided with a push plate device 3, which includes a fixed seat 3.4, a push plate clamp connecting plate 3.6, a push plate clamp 3.5, a cylinder 3.1 and a push plate push rod 3.2; wherein: the fixed seat 3.4 is fixed to the frame 1, and the push plate clamp 3.5 is provided on the push plate clamp connecting plate 3.6, and is used to clamp and push the cartridge case carrier plate 9 and the bullet carrier plate 11. Preferably, the two push plate clamps 3.5 are symmetrically provided on the push plate clamp connecting plate 3.6 to achieve For a better clamping and pushing effect, the push plate push rod 3.2 is used to support and connect the push plate clamp connecting plate 3.6 to one side of the fixed seat 3.4. The push plate push rod 3.2 passes through the fixed seat 3.4 and is connected to the other side of the fixed seat 3.4 through the connecting flange 3.3. Preferably, the two push plate push rods 3.2 are symmetrically arranged at both ends of the fixed seat 3.4; the other side of the fixed seat 3.4 is equipped with a cylinder 3.1, which is used to provide power support for the push plate push rod 3.2. Specifically, refer to Figure 10 When the cylinder extends, the wedge-shaped pressure block 9.3 moves downward, releasing the cartridge case and compressing the spring. When the cylinder retracts, the wedge-shaped pressure block 9.3 moves upward, clamping the cartridge case and causing the spring to rebound. The push plate device 3 mainly performs two functions: first, it pushes the cartridge case carrier plate 9 to the positioning stop cylinder 8 for rough positioning; second, it pushes the empty carrier plate after press-fitting to the next process.

[0049] Prior art ammunition press-fitting equipment primarily includes traditional mechanical, hydraulic, and servo motor press-fitting units. These differing drive systems result in varying speed and pressure control. Mechanical press-fitting units suffer from unstable loading, long transmission chains, inadequate transmission precision, and uncontrollable operating speed and pressure. Hydraulic press-fitting units are complex, operate at a slower speed, and are relatively expensive. Existing servo press-fitting units typically only fit a limited number of items at a time, failing to meet cycle requirements. If defective products are produced due to insufficient press-fitting, the source of the problem cannot be promptly traced. In the embodiments of the present invention, the servo power unit is directly driven by an AC servo motor, eliminating the need for a flywheel, clutch, or brake. This results in a simpler structure, higher transmission precision, and controllable operating speed and pressure, offering increased flexibility. A servo motor coupled with a worm gear reducer is used as the press-fitting power source for the ball screw longitudinal motion unit 5. The servo power unit 2 is controlled by a frequency converter and offers variable speed, resulting in high precision and guaranteed press force and depth during the press-fitting process. Moreover, as long as the servo motor ensures sufficient output force, the modular pressing mechanism in the embodiment of the present invention can be configured with 100, 200 or even more single-module pressing head units according to the beat requirements; since each single-module pressing head unit is equipped with a pressure sensor, the pressing force can be fed back to the control system to facilitate the later tracing of unqualified pressing heads.

[0050] In some specific embodiments, the device further includes a positioning and blocking cylinder 8 provided at the pressing position, and the positioning and blocking cylinder 8 is used to roughly position the transported cartridge case carrier plate 9 and warhead carrier plate 11 in the length direction and width direction of the frame 1 respectively.

[0051] Furthermore, a positioning pin 6.1 is provided at the bottom of the press-fitting unit 6, and positioning pin holes cooperating with the positioning pin 6.1 are provided on the cartridge case carrier plate 9 and the bullet carrier plate 11. Figure 6 The positioning pin hole 9.8 on the cartridge case carrier plate 9 is inserted; the pressing unit 6 carries a plurality of pressing head units 7, and moves the plurality of pressing head units 7 to the designated position for precise positioning with the cartridge case carrier plate 11 or the cartridge case carrier plate 9.

[0052] In some specific embodiments, the ball screw longitudinal motion unit 5 is connected to the press-fitting unit 6 via a screw nut, driving the press-fitting unit 6 to move up and down. The ball screw transverse motion unit 10 transports the loaded bullet carrier 11 to the press-fitting position, and after the vacuum suction head 7.5 removes the bullet, the empty carrier is transported back to the loading position.

[0053] In some specific embodiments, the cartridge case carrier plate 9 is transported to the press-fitting position by a belt conveyor unit 4. The belt conveyor device plays a role in transporting the cartridge case carrier plate 9, and transports the cartridge case carrier plate 9 to the press-fitting position.

[0054] A high-efficiency modular flexible bullet-binding device capable of press-loading multiple bullets at a time in a preferred embodiment of the present invention operates as follows:

[0055] After the warhead carrier 11 is loaded from the warhead feeding unit, it is transported to the pressing position by the ball screw transverse motion unit 10. At this time, the positioning blocking cylinder 8 performs rough positioning on the warhead carrier 11 in two directions, and the servo power unit 2 drives the ball screw longitudinal motion unit 5 to rotate, and the screw nut drives the pressing unit 6 to move downward. The positioning pin 6.1 in the pressing unit 6 performs fine positioning on the warhead carrier 11, and the 100 pressure head units 7 on the pressing unit 6 are moved and positioned on the warhead carrier 11. The vacuum suction head 7.5 on the pressure head unit 7 inhales air, and at the same time, the external cylinder pushes the push rod 9.1 on the warhead carrier 11 to relax the wedge-shaped pressure block 9.3 on the warhead, so that the vacuum suction head 7.5 successfully absorbs the warhead, and the empty warhead carrier 11 is transported back to the warhead feeding unit by the ball screw transverse motion unit 10, and the pressing unit 6 that absorbs the warhead is moved by the ball screw longitudinal motion unit 5 rises a distance, and then the cartridge case carrier plate 9 is transported to the pressing position by the belt conveyor unit 4. It is also roughly positioned by the positioning blocking cylinder 8. The pressing unit 6 that sucks the bullet moves downward through the ball screw longitudinal unit 5. After fine positioning by the positioning pin 6.1, the vacuum suction head 7.5 of the pressing head unit 7 sucks the bullet to the cartridge case for press-fitting. After the press-fitting is completed, air is blown in the opposite direction to leave the completed bullet in the cartridge case carrier plate 9. At the same time, the external cylinder retracts, the spring 9.5 in the cartridge case carrier plate 9 rebounds, and the wedge-shaped pressure block 9.3 clamps the bullet. After the press-fitting is completed, the pressing unit 6 moves upward through the ball screw longitudinal movement unit 5. The piston rod of the cylinder 3.1 in the push plate device 3 extends, and the two push plate push rods 3.2 push the push plate clamp connecting plate 3.6 together. The push plate clamp 3.5 on the push plate clamp connecting plate 3.6 clamps the empty cartridge case carrier plate 9 and enters the next blanking process.

[0056] The modular, flexible, small-caliber ammunition binding device in the above-mentioned embodiment of the present invention utilizes a modular press head assembly method. Depending on the production line's cycle time requirements, it can press dozens or even hundreds of items at a time, improving assembly efficiency. The press head unit is traceable; if there are defective products, the specific press head with the problem can be traced, allowing for rapid adjustments and reducing the equipment's defect rate. Furthermore, the use of customized vacuum suction heads allows a single device to be equipped with multiple models of vacuum suction heads, thereby meeting the assembly requirements of different types of bullets and making the device more flexible. Furthermore, the servo power unit in the embodiment of the present invention can control speed and movement speed with high precision, ensuring the assembly force and depth during the assembly process. Therefore, the modular, flexible, small-caliber ammunition binding device in the above-mentioned embodiment of the present invention can improve the efficiency of small-caliber ammunition binding devices and reduce product defect rates.

[0057] The above describes specific embodiments of the present invention. It should be understood that the present invention is not limited to the specific embodiments described above, and those skilled in the art may make various modifications or variations within the scope of the claims without affecting the essence of the present invention. The above preferred features may be used in any combination as long as they do not conflict with each other.
