[0031] See also Figure 1 - Fig.11In an embodiment of the present invention, a needle pressing processing device includes a device body 1, and a bending mechanism is arranged on one side of the top of the device body 1; preferably, a base 301 is arranged in the device body 1, and the end of the base 301 extends to the bottom of the bending mechanism, and a needle pressing groove 3 is arranged on the top of one end of the base 301 close to the bending mechanism. The needle pressing groove 3 is arranged in an array on the base 301 in multiple groups, so as to achieve the effect of placing multiple groups of needle pressing pins. When the needle pressing pin is bent, the end of the needle pressing pin is bent. After the end of the moving extension base 301 is stretched out, the bending mechanism can be started to bend the end of the pressing pin. A loading area 4 is provided on the side of the top of the base 301 away from the pressing pin groove 3. The side wall of the equipment body 1 is provided with material ports on both sides of the loading area 4. A pressing pin material box 2 is provided on the side of the material port away from the loading area 4. The pressing pin material box 2 is installed on the equipment body 1. The two sets of material ports are respectively the inlet and outlet for the pressing pin to enter and exit the loading area 4. Similarly, the pressing pin material box 2 provided at the inlet is for A feed box for conveying press needles is provided in the loading area 4, and the press needle material box 2 arranged at the outlet is a collection box for press needles. A feeding mechanism is arranged on both sides of the inner wall of the equipment body 1. When in use, press needles are conveyed into the loading area 4 through the feed port at the inlet, and the press needles cover the loading area 4 under the action of their own rolling. At this time, the feeding mechanism is at the end of the loading area 4 away from the base 301. When the press needles cover the bottom of the loading area 4, the feeding mechanism is started to push the press needles to move toward the base 301. At this time, the press needles on the loading area 4 Although the press pins are in a one-to-one correspondence with the press pin grooves 3, there are states where some of the press pin tips correspond to the press pin grooves 3 and some do not correspond to the press pin grooves 3. Therefore, at this time, the movement of the feeding mechanism will only push the press pins corresponding to the press pin grooves 3 into the press pin grooves 3 for subsequent processing. The press pins whose tips do not correspond to the press pin grooves 3 can enter the collection box through the outlet to complete the collection after the other press pins are completely pushed into the press pin grooves 3. This process can be repeated without placing the press pins one by one on the press pin grooves 3, thereby improving efficiency.

[0032] A cleaning assembly is provided below the bending mechanism and is provided on the inner wall of the equipment body 1. When the feeding mechanism moves in a direction away from the base 301, the feeding mechanism drives the cleaning assembly to move horizontally. When the feeding mechanism makes the end of the press pin extend out of the base 301 for a fixed distance, the bending mechanism is started to perform bending processing. After completion, the bending mechanism is reset and the feeding mechanism is started again to move in a direction away from the base 301, so that the processed press pin is transported out of the press pin slot 3. Subsequently, the cleaning assembly cleans the bending mechanism to avoid plastic deformation of the press pin under pressure during the bending process, especially near the bending point, when it is subjected to strong extrusion and shear force, resulting in debris particles falling off the surface layer due to the force and adhering to the bending mechanism.

[0033] It should be noted that: one end of the equipment body 1 corresponding to the bending mechanism is provided with a discharge port 12 for discharging the processed press pins, and a conveyor belt or a transfer and storage device for collecting and conveying the press pins after processing can be provided in the discharge port 12 corresponding to the position at the end of the base 301, and a sealing plate 5 is slidingly provided at the material port, and a lifting component for lifting the press pins is provided at the bottom of the press pin material box 2, and a driving component for controlling the extension and retraction of the sealing plate 5 in the material port can also be provided in the press pin material box 2. Specifically, when there is no press pin in the loading area 4, a group of press pins in the press pin material box 2 are firstly The driving component drives the sealing plate 5 of the inlet to retract in the pressing needle material box 2, so that the inlet is connected with the pressing needle material box 2, and then a group of lifting components in the pressing needle material box 2 is started to make the pressing needle in the pressing needle material box 2 move upward, and then under the action of its own rolling, it rolls into the loading area 4 through the pressing needle material box 2 and the material port, and then the driving component is used to make the sealing plate 5 seal the material port again. When the feeding mechanism completes the pressing needle loading port, the remaining pressing needles can be collected through another group of pressing needle material boxes 2, and the pressing needle material boxes 2 are all mounted on the equipment body 1 by snap-on connection, so as to achieve the effect of easy replacement and convenient use.

[0034] See also Figure 1 - Figure 4 , Figure 6 , Fig. 9 Preferably, the feeding mechanism includes a support rod 7; a feeding plate 16 is slidably provided at the bottom of the support rod 7, and a plurality of groups of feeding plates 16 are arranged in an array, and the bottom end of the feeding plate 16 close to the base 301 is rounded, and square blocks are provided at both ends of the support rod 7. The inner wall of the equipment body 1 is symmetrically provided with guide rails 9 along the center, and the guide rails 9 are arranged in a runway shape. The support rod 7 is slidably connected to the guide rails 9 through square blocks. When the support rod 7 slides on the guide rails 9 and is at the end of the feeding area 4 away from the base 301, the support rod 7 remains parallel to the bottom of the feeding area 4, and the feeding plate 16 approaches the bottom of the feeding area 4 under the action of gravity. When the feeding area 4 is full of press pins, when the support rod 7 moves toward the press pin groove 3, under the action of the feeding plate 16, the press pins of some press pins corresponding to the press pin groove 3 will be pushed by the feeding plate 16, while on the contrary, the press pins whose needle tips correspond to the feeding plate 16, their corresponding loading plate 16 will move upward under the action of the curved surface of the needle tip, so that they cannot be pushed to move toward the press pin groove 3, and through the action of the feeding plate 16, the press pins entering the press pin groove 3 are always kept in an aligned state, thereby facilitating subsequent processing.

[0035] Furthermore, preferably, a tooth groove 902 is provided on the inner wall of the guide rail 9, and the end of the square block away from the support rod 7 is rotatably connected to a gear 901, and the gear 901 and the tooth groove 902 are transmission connected. It should be noted that: a motor for driving the gear 901 to rotate is provided on the support rod 7. When in use, the motor is started to drive the gear 901 to rotate. The rotation of the gear 901 will be under the action of the tooth groove 902 and the restriction of the support rod 7 by the square block, so that the support rod 7 can be remotely moved along the two sets of guide rails 9.

[0036] See also Figure 1 - Figure 3 , Fig. 9 Preferably, a pressure rod 6 is rotatably arranged in the device body 1, and the pressure rod 6 is arranged at a position close to the base 301 in the loading area 4, and the rotation connection between the pressure rod 6 and the device body 1 is arranged above the guide rail 9, and a torsion spring is arranged at the connection between the two, through which the pressure rod 6 automatically rotates to a state perpendicular to the loading area 4 when not restricted, and positioning grooves 602 are arranged at both ends of the bottom of the pressure rod 6, and a limiting rod 601 is elastically arranged in the side wall of the device body 1 through a spring, and the limiting rod 601 is arranged at a position corresponding to the loading area 4, and bosses are arranged at both ends of the limiting rod 601, a group of bosses close to the positioning groove 602 slide out of the side wall of the device body 1 and slide in cooperation with the positioning groove 602, and another group of bosses slide into the end of the guide rail 9 close to the loading area 4 away from the needle pressing groove 3 and slide in cooperation with the gear 901, when the support rod 7 moves toward the base 301, the support rod 7 drives the pressure rod 6 to rotate upward, so that a group of bosses cooperate with the positioning groove 602.

[0037] When in use, in the initial state where the pressing pins are spread all over the feeding area 4, the support rod 7 is at the end of the guide rail 9 away from the bending mechanism, and the pressure rod 6 is in a state of being parallel to the feeding area 4 under the action of the positioning groove 602 and a group of protrusions. At this time, the support rod 7 is started to move toward the pressing pin groove 3 on the guide rail 9, and then the gear 901 slides with the other group of protrusions and pushes the other group of protrusions to move away from the guide rail 9, and then the limit rod 601 separates a group of protrusions from the positioning groove 602, and then the pressure rod 6 rotates to the feeding area under the action of the torsion spring. 4 is in a vertical state, so that the bottom of the pressing rod 6 is in a state of being in contact with the top of one end of the pressing pin close to the pressing pin groove 3. In this way, when the loading plate 16 loads the pressing pin, the pressing pin whose needle tip corresponds to the loading plate 16 is prevented from tilting away from one end of the loading plate 16 under the action of the loading plate 16. When the support rod 7 moves to the position of the pressing rod 6, the support rod 7 will push the pressing rod 6 to rotate upward. When the pressing rod 6 rotates to the position of a group of convex columns, it will slide with the convex columns to complete the restriction on the pressing rod 6, thereby achieving the stability of the pressing pin during the loading process.

[0038] See also Figure 2 - Figure 3 , Figure 5 , Fig.10 - Fig.11 Preferably, the cleaning assembly includes a cleaning plate 19; the cleaning plate 19 is arranged below the bending mechanism, and the side wall of the cleaning plate 19 at one end away from the base 301 is rotatably cooperated with a reciprocating screw 20. When the reciprocating screw 20 rotates, the cleaning plate 19 performs horizontal reciprocating motion below the bending mechanism, and the cleaning plate 19 can wipe and clean the bending part of the bending mechanism, thereby avoiding the problem of metal debris attached thereto, which causes the surface of the pressing needle to be scratched during the next bending. The two ends of the reciprocating screw 20 are rotatably connected to the side walls of the equipment body 1. In addition, a fixing rod is also provided on the side wall of the cleaning plate 19 near the reciprocating screw 20 to ensure the stability of the movement of the cleaning plate 19 under the action of the reciprocating screw 20. The reciprocating screw 20 specifically includes two thread grooves with the same pitch and opposite rotation directions thereon, and smooth transition curves are provided at both ends of the thread grooves with different rotation directions to ensure the continuity and stability of the movement of the cleaning plate 19.

[0039] Further, preferably, ratchets are fixedly provided at both ends of the reciprocating screw 20, and a tooth plate 18 is meshed with the bottom of the ratchet. The tooth plate 18 is elastically slidably arranged in the side wall of the equipment body 1 by a spring, so that when there is no external force, the end of the tooth plate 18 close to the discharge port 12 is close to the cleaning plate 19, and the end of the tooth plate 18 away from the base 301 is slidably fitted with a connecting tube 10, and the end of the connecting tube 10 away from the tooth plate 18 extends to the end of the base 301 close to the loading area 4. When pushed toward the cleaning plate 19 by the connecting tube 10, the connecting tube 10 will push the tooth plate 18 to move in the direction away from the cleaning plate 19. At this time, The movement of the tooth plate 18 cannot drive the reciprocating screw 20 to rotate through the ratchet. When the connecting tube 10 is not subjected to force and restriction, the tooth plate 18 moves to the cleaning plate 19 and resets under the action of elasticity. At this time, the tooth plate 18 can drive the reciprocating screw 20 to rotate through the ratchet, and at the same time push the connecting tube 10 to move and reset. A stabilizing block 101 is provided on the outer periphery of one end of the connecting tube 10 close to the loading area 4, and a stabilizing groove 102 that slides with the stabilizing block 101 is provided on the side wall of the equipment body 1. The stabilizing block 101 and the stabilizing groove 102 are cooperated to ensure that the connecting tube 10 remains stable during the remote operation process, thereby better pushing the tooth plate 18 to move.

[0040] See also Figure 1 - Figure 4 , Figure 6 - Figure 8 , Fig.11Preferably, a groove is provided on the side of the support rod 7 away from the loading plate 16, and the inner wall of the groove is elastically slidably connected to the cross bar 801 through a spring, the interior of the cleaning block 8 is a hollow structure, and the bottom array of the cross bar 801 is provided with cleaning blocks 8, and the number and position of the cleaning blocks 8 are set one by one corresponding to the number and position of the press needle grooves 3. When the support rod 7 pushes the press needle onto the press needle groove 3 through the loading plate 16, the cleaning block 8 will move downward and fit with the side wall of the press needle groove 3, and then the inner wall of the press needle groove 3 will be scraped and cleaned during the movement of the support rod 7 to avoid the presence of metal debris or other particles thereon, thereby affecting the processing of the press needle, and when the cleaning block 8 moves to the bottom of the end of the guide rail 9 close to the base 301 when the support rod 7 moves, the cleaning block 8 will shrink in the groove under the action of the base 301, thereby avoiding the problem of the cleaning block 8 not moving and getting stuck.

[0041] Further, preferably, both ends of the cross bar 801 are connected with a hose 112, and one end of the hose 112 away from the cross bar 801 is fixedly connected with an inner tube 111, and the outer periphery of the inner tube 111 is slidably connected with an adapter tube 11, and both ends of the support rod 7 are fixedly provided with mounting plates for mounting the adapter tube 11, and the adapter tube 11 is rotatably connected to the mounting plate. The adapter tube 11 is installed on the top of the support rod 7 through the mounting plate, and a torsion spring is provided at the rotational connection between the adapter tube 11 and the mounting plate, so that when the adapter tube 11 is not subjected to external force, it is connected with the mounting plate. The connecting tube 10 maintains a parallel corresponding position, the adapter tube 11 and the opposite end of the connecting tube 10 are slidably matched, and a bellows 17 is fixedly provided on the side of the tooth plate 18 close to the connecting tube 10, the end of the connecting tube 10 away from the adapter tube 11 slides into the bellows 17, and the end of the bellows 17 away from the tooth plate 18 is fixed to the side wall of the equipment body 1, and the end of the bellows 17 away from the tooth plate 18 is arranged on the baffle, and the baffle is fixed to the side wall of the equipment body 1 by a clamp or bolts, and the connecting tube 10 seals and passes through the baffle into the bellows 17.

[0042] It should be noted that: an absorption groove is provided at the bottom of the cleaning block 8, the top of the absorption groove is connected to the cross bar 801, and a spacer 802 is provided on the side of the cleaning block 8 close to the loading plate 16. When the cleaning block 8 moves downward and fits into the needle pressing groove 3, there is a gap between the spacer 802 and the needle pressing groove 3. A section of deformable material is provided at the connecting tube 10 away from the bellows 17 and close to the stabilizing block 101, and the stabilizing block 101 includes a ring and a slider. The ring is fixedly sleeved on the outer periphery of the connecting tube 10, the slider is slidably connected to the stabilizing groove 102, and the ring and the slider are rotationally connected, and a torsion spring is provided at the rotational connection between the ring and the slider to achieve that the end of the connecting tube 10 close to the adapter tube 11 always maintains a state corresponding to the adapter tube 11, and can also rotate to a certain extent. A notch is provided at the end of the connecting tube 10 extending into the bellows 17.

[0043] Furthermore, preferably, the side of the support rod 7 away from the loading plate 16 is elastically connected to the trigger rod 113 through an elastic column, the top of the trigger rod 113 is fixedly provided with a semicircular plate that slides with the end of the inner tube 111, and the bottom of the trigger rod 113 is fixedly provided with a triangular plate that slides with the cross bar 801, and the cleaning block 8 is at the end of the support rod 7 that is in the loading area 4 away from the base 301. When the loading plate 16 naturally hangs down, the bottom height of the cleaning block 8 is above the top height of the pressing pin.

[0044] During specific use, when the support rod 7 cooperates with the loading plate 16 to complete the loading of the press pin and the support rod 7 is at one end of the press pin groove 3 close to the loading area 4, the ends of the adapter tube 11 and the connecting tube 10 correspond, and the bellows 17 is in a contracted state. The triangular bag on the trigger rod 113 cooperates with the cross bar 801 to limit the cross bar 801 to the upper end in the groove, thereby making the bottom height of the cleaning block 8 higher than the top height of the press pin in the loading area 4; when the bending work of the end of the press pin is completed, the support rod 7 is started to continue to move under the guidance of the guide rail 9. When the adapter tube 11 moves forward, the end of the connecting tube 10 extends into the adapter tube 11. As the adapter tube 11 moves, the end of the connecting tube 10 pushes the inner tube 111 to move away from the adapter tube 11 and extends out of the adapter tube 11. When the inner tube 111 moves, it pushes the trigger rod 113 to move away from the adapter tube 11. The trigger rod 113 moves so that the bottom triangular plate thereof is separated from the cross bar 801. At this time, the cross bar 801 moves toward the pin pressing groove 3 under the action of elasticity, and makes the bottom of the cleaning block 8 slide and fit with the pin pressing groove 3. Then The support rod 7 moves to push the connecting tube 10 toward the bellows 17, so that the bellows 17 moves and expands toward the lower material port 12, thereby generating negative pressure in the bellows 17, pushing the connecting tube 10 and the inner tube 111, the hose 112, and the cross bar 801 to absorb external air from the absorption tank. In this process, if there are particles in the needle pressing groove 3, they will be sucked into the bellows 17. When the support rod 7 moves to the end of the guide rail 9 close to the lower material port 12 and moves downward, the adapter tube 11 and the connecting tube 10 will rotate relative to each other, so that as the support rod 7 moves to the end of the guide rail 9 close to the lower material port 12 and moves downward, the adapter tube 11 and the connecting tube 10 will rotate relative to each other, so that The continued movement of the support rod 7 realizes automatic separation, and then the adapter pipe 11 and the connecting pipe 10 automatically rotate and reset, and a one-way valve can be provided at the notch at one end of the connecting pipe 10 in the bellows 17, and a one-way valve is provided at the baffle, and a filter is provided at the one-way valve on the baffle, so that when the bellows 17 expands, the one-way valve at the notch opens and the one-way valve on the baffle closes, and when the bellows 17 contracts, the one-way valve at the notch closes, the one-way valve at the baffle opens, and the filter prevents particulate matter from being discharged with the air in the bellows 17 when the air is discharged.

[0045] See also Figure 1 - Fig.11Preferably, the bending mechanism includes a bending plate 13; a telescopic cylinder is provided on the top of the bending plate 13, and the telescopic cylinder is installed on the top of the equipment body 1; a synchronous plate 15 is fixedly provided on one side of the bending plate 13 close to the base 301; the bottom of the synchronous plate 15 is elastically connected to the fixed plate 14 through a spring; the bending plate 13, the fixed plate 14, and the synchronous plate 15 are slidably provided in the equipment body 1, and a telescopic rod is fixedly provided between the fixed plate 14 and the inner wall of the equipment body 1; the cleaning plate 19 is slidably matched with the bottom of the bending plate 13 The bottom of the bending plate 13 corresponds to the end of the base 301 away from the loading area 4, and the fixed plate 14 corresponds to the top of the press pin groove 3. At the same time, the bottom of the fixed plate 14 is provided with a fixed groove corresponding to the press pin groove 3 one by one. The bottom height of the fixed plate 14 is lower than the bottom height of the bending plate 13. In this way, when the bending plate 13 moves downward, the fixed plate 14 first contacts with the press pin, so that when the bending plate 13 is bent, the press pin is fixed, and the reciprocating screw rod 20 and the cleaning plate 19 will not affect the movement of the bending plate 13 and the fixed plate 14.

[0046] During specific use, when the feeding of the press pin on the press pin slot 3 is completed through the feeding mechanism, the bending plate 13 and the fixed plate 14 are both retracted in the side wall of the equipment body 1 and are above the guide rail 9. At this time, the cleaning plate 19 is in a state of fitting the inner wall of one side of the equipment body 1; when the press pin is bent, the telescopic cylinder is started to push the bending plate 13 to move downward, and the bending plate 13 moves downward and pushes the fixed plate 14 to move downward through the action of the synchronization plate 15 and the spring, and the telescopic movement can provide stability for the movement of the fixed plate 14. The downward movement of the fixed plate 14 will contact the press pin on the press pin slot 3 before the bending plate 13 and complete the pressing of the press pin before the bending plate 13 contacts the press pin. Fixed, and when the processing of the pressing pin is completed, the bending plate 13 and the fixed plate 14 are moved and reset to the initial state through the telescopic cylinder, and then the support rod 7 is started to move to push the pressing pin to the unloading port 12 to complete the unloading. In this process, the support rod 7 pushes the tooth plate 18 to move toward the unloading port 12 through the cooperation of the adapter tube 11, the connecting tube 10, and the bellows 17. When the adapter tube 11 and the connecting tube 10 are separated, the tooth plate 18 moves and resets and drives the reciprocating screw 20 to rotate through the ratchet. The rotation of the reciprocating screw 20 drives the cleaning plate 19 to move from one side of the inner wall of the equipment body 1 to the other side. In this process, the cleaning plate 19 completes the cleaning work on the bottom of the bending plate 13.

[0047] See also Figure 1-Figure 12 Preferably, a spherical press needle processed by the above-mentioned press needle processing equipment includes a press needle body, wherein the two ends of the press needle body are respectively provided with a needle tip and a needle tail, and a sphere is provided on the needle tail, and the diameter of the sphere is larger than the diameter of the press needle body, and the sphere is formed at the needle tail of the press needle body by high-temperature balling.

[0048] Specifically, when in use, the pressing needle body is loaded into the pressing needle groove 3 through the loading mechanism and then bent. When the pressing needle completes the bending work, the bent part of the pressing needle body will become the needle tail in the subsequent high-temperature balling, making it convenient for the pressing needle body to be loaded while maintaining good stability. During high-temperature balling, the bent part of the pressing needle body is melted and then balled, ensuring that the ball size of the needle tail is the same, avoiding high-temperature balling without bending the pressing needle body. The problem of different ball sizes at the needle tail or different sizes of the pressing needle body may occur during high-temperature balling due to inconsistent placement of the pressing needle body or insufficient margin for balling.

[0049] In addition, the tail of the press-pin needle body can be formed into a ball by dispensing or injection molding, and the bent portion of the press-pin needle body can support the formed ball, making it difficult for the two to fall off.
