DETAILED DESCRIPTION

[0029] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0030] like Figure 1 、 Figure 2 As shown, an embodiment of the present invention provides a compatible twist needle crimping device, which includes: a base 1, a needle sleeve loading mechanism 2, a twist needle loading mechanism 3, an identification and grabbing mechanism 4, and a crimping mechanism 5. The needle sleeve loading mechanism 2, the twist needle loading mechanism 3, the identification and grabbing mechanism 4, and the crimping mechanism 5 are fixed on the base 1. The needle sleeve loading mechanism 2 is used for needle sleeve loading. The identification and grabbing mechanism 4 is used to identify and grab the needle sleeve on the needle sleeve loading mechanism 2 and move it to the crimping mechanism 5. The twist needle loading mechanism 3 is used to transport the twist needle to the crimping mechanism 5. The crimping mechanism 5 is used to push the needle sleeve onto one end of the twist needle and crimp it.

[0031] Specifically, the base 1 has a flat fixed surface, to which the needle sheath loading mechanism 2, the twist needle loading mechanism 3, the identification and grasping mechanism 4, and the crimping mechanism 5 are fixed. The base 1 is equipped with power supply circuits and air and oil supply circuits, which are connected to the needle sheath loading mechanism 2, the twist needle loading mechanism 3, the identification and grasping mechanism 4, and the crimping mechanism 5 to ensure the normal operation of the needle sheath loading mechanism 2, the twist needle loading mechanism 3, the identification and grasping mechanism 4, and the crimping mechanism 5. The power supply circuits and air and oil supply circuits are conventional techniques in the art and can be reasonably adjusted by those skilled in the art according to actual conditions, so they are not described in detail here.

[0032] Specifically, the needle sheath loading mechanism 2 includes a needle sheath hopper 21, a needle sheath tray 22, and a shaking mechanism 23. The needle sheath tray 22 is fixed to the shaking mechanism 23, and the shaking mechanism 23 drives the needle sheath tray 22 to reciprocate in a horizontal plane to achieve a shaking effect. The needle sheath hopper 21 is located on top of the needle sheath tray 22, and the discharge end of the needle sheath hopper 21 is located above the needle sheath tray 22. During use, needle sheaths are poured into the needle sheath hopper 21, and the needle sheaths pass through the needle sheath hopper 21 and fall into the needle sheath tray 22. The shaking mechanism 23 drives the needle sheath tray 22 to reciprocate in a horizontal plane, so that the needle sheaths in the needle sheath tray 22 do not overlap, which facilitates the identification and grasping mechanism 4 to identify and grasp the twisted needles.

[0033] Furthermore, to prevent the needle sheath hopper 21 from obstructing the twisted needles in the needle sheath tray 22, the needle sheath loading mechanism 2 includes a hopper bracket 24 and an inclined slide 25. The hopper bracket 24 is fixed to one side of the upper shaking mechanism 23, and the inclined slide 25 is fixed to the hopper bracket 24 at an angle. The lower end of the inclined slide 25 is located above the needle sheath tray 22. The needle sheath hopper 21 is fixed to the hopper bracket 24 and is located above the higher end of the inclined slide 25. The needle sheath slides into the needle sheath tray 22 through the inclined slide 25.

[0034] Specifically, the twist needle feeding mechanism 3 includes a circular vibration disk 31, a vibrator and a feed pipe 32. The circular vibration disk 31 is fixed on the vibrator. A spiral track is provided on the circular vibration disk 31. One end of the feed pipe 32 is connected to the spiral track, and the other end is connected to the crimping mechanism 5. The vibrator can drive the circular vibration disk 31 to vibrate in the vertical direction and torsional vibration around its vertical axis, so that the twist needles in the circular vibration disk 31 rise along the spiral track and are fed into the feed pipe 32.

[0035] Specifically, the identification and grasping mechanism 4 includes a stand 41, an identification module 42, a six-axis robot 43 and a chuck 44. The stand 41 is fixed on the base 1, and the identification module 42 is fixed on the stand 41 and is located above the needle sleeve material tray 22. The identification module 42 is electrically connected to the six-axis robot 43, and the six-axis robot 43 is fixed on the base 1. The chuck 44 is fixed on the active end of the six-axis robot 43 and is electrically connected to the identification module 42. The active range of the six-axis robot 43 covers the needle sleeve material tray 22 and the crimping mechanism 5. The identification module 42 is used to identify and locate the needle sleeve in the needle sleeve material tray 22, and can drive the six-axis robot 43 to grab the needle sleeve that has been identified and located and send it into the crimping mechanism 5.

[0036] Furthermore, the recognition module 42 includes a camera and a processing module, and the processing module is electrically connected to the camera, the six-axis robot 43, and the chuck 44. The camera takes a picture of the needle sheath tray 22 and sends the generated image to the processing module. The processing module recognizes and locates the needle sheath based on the image, determines the position of the needle sheath, and drives the movable end of the six-axis robot 43 to move to the position of the needle sheath. The chuck 44, driven by the recognition module 42, then drives the movable end of the six-axis robot 43 to move to the crimping mechanism 5. The chuck 44 can release the needle sheath under the drive of the recognition module 42, allowing the needle sheath to be inserted into the crimping mechanism 5.

[0037] Specifically, such as Figure 3-Figure 7 As shown, the crimping mechanism 5 includes a needle sleeve placement platform 51, a translation docking component 52, a crimping component 53, a twist needle pushing component 54 and a needle sleeve pushing component 55. The needle sleeve placement platform 51 is arranged on the base 1 for placing twist needles. The crimping component 53 is arranged on one side of the needle sleeve placement platform 51, and the needle sleeve pushing component 55 is arranged on the other side of the needle sleeve placement platform 51. The needle sleeve pushing component 55 has a retractable movable end that can push the needle sleeve part located on the needle sleeve placement platform 51 into the crimping component 53. The translation docking component 52 has a translation block 521 that can translate relative to the crimping component 53. The translation block 52 1 is provided with a twist needle loading hole 522 for loading twist needles, and the translation block 521 has a twist needle loading state in which the twist needle loading hole 522 is docked with the discharge end of the twist needle feeding mechanism 3 and a twist needle insertion state in which the twist needle loading hole 522 is docked with the crimping component 53, and the twist needle insertion component 54 has a pushing end coaxial with the twist needle loading hole 522 in the twist needle insertion state, and the pushing end can move relative to the translation block 521 to push the twist needle in the twist needle loading hole 522 into the crimping component 53 and pass it through the needle sleeve, and the crimping component 53 is used to crimp the twist needle with the needle sleeve.

[0038] Furthermore, the needle sheath placement platform 51 is provided with a cross-shaped groove 511 for receiving the needle sheath. The cross-shaped groove 511 extends through the needle sheath placement platform 51 in a direction perpendicular to the crimping component 53. During use, the movable end of the needle sheath insertion component 55 can extend into the cross-shaped groove 511, pushing the needle sheath within the cross-shaped groove 511 toward the crimping component 53. The purpose of using the cross-shaped groove 511 is to accommodate needle sheaths of various shapes, such as straight, cross, L, T, etc. It should be noted that the various needle sheaths mentioned here differ only in shape; the diameter of their needle bodies is the same.

[0039] Furthermore, the cross-shaped groove 511 is formed by the intersection of a first groove body perpendicular to the crimping component 53 and a second groove body parallel to the crimping component 53. The inner diameter of the first groove body is the same as the diameter of the needle sleeve. The movable end of the needle sleeve pushing component 55 can extend into the first groove body to push the needle sleeve to move along the first groove body; the inner diameter of the second groove body is larger than the diameter of the needle sleeve. The purpose of this arrangement is to allow the needle sleeve portion located in the second groove body to have space to move along the first groove body, thereby facilitating the needle sleeve pushing component 55 to push the needle sleeve located in the cross-shaped groove 511 into the crimping component 53.

[0040] Specifically, the translation docking component 52 includes a translation block 521 and a translation driver. The translation driver is fixed on the base 1. The movable end of the translation driver is fixed to the translation block 521 and is used to push the translation block 521 to move. The twist needle loading hole 522 is opened on the translation block 521. When the movable end of the translation driver is extended to the maximum state, the twist needle loading hole 522 is docked with the twist needle feeding mechanism 3 and enters the twist needle loading state. When the movable end of the translation driver is contracted to the minimum state, the twist needle loading hole 522 is docked with the crimping component 53 and enters the twist needle insertion state.

[0041] Specifically, the crimping component 53 includes a fixed ring 531 and at least one crimping assembly 532. The crimping assembly 532 is fixed to the inner surface of the fixed ring 531 and has two relatively movable crimping surfaces. The crimping surfaces are symmetrical about the center of the fixed ring 531 and are capable of crimping a needle sleeve positioned at the center of the fixed ring 531. It should be noted that when the movable end of the translational actuator is retracted to its minimum position, the twist needle loading hole 522 is aligned with the center of the fixed ring 531.

[0042] In this embodiment, the crimping component 53 has two crimping assemblies 532, and the axes of the two crimping assemblies 532 are perpendicular to each other. The two crimping assemblies 532 can crimp the twist pins at the center of the fixing ring 531 from four directions.

[0043] Furthermore, the crimping assembly 532 includes a first crimping block 532a, a second crimping block 532b, a first driver 532c, and a second driver 532d. The first driver 532c and the second driver 532d are relatively fixed on the inner wall of the fixed ring 531. The first crimping block 532a is fixed to the movable end of the first driver 532c, and the second driver 532d is fixed to the movable end of the second driver 532d. The movable end of the first driver 532c and the movable end of the second driver 532d can drive the first crimping block 532a and the second crimping block 532b to move toward or away from each other.

[0044] Specifically, the twist needle pushing component 54 includes a twist needle pushing drive component, a telescopic component 541, and an ejector pin 542. The twist needle pushing drive component is fixed to the telescopic component 541, and can drive the telescopic component 541 to move in a direction perpendicular to the crimping component 53. The ejector pin 542 is fixed on the telescopic component 541, is coaxial with the twist needle loading hole 522 in the twist needle pushing state, and is located on the side of the translation block 521 away from the crimping component 53. The telescopic component 541 moves, driving the ejector pin 542 to push the twist needle in the twist needle loading hole 522 into the crimping component 53.

[0045] Specifically, the needle sheath insertion component 55 includes a needle sheath insertion driver, an elastic insertion member 551, and a push block 552. The movable end of the needle sheath insertion driver is elastically connected to the elastic insertion member 551, capable of driving the elastic insertion member 551 to move in a direction perpendicular to the crimping member 53. The push block 552 is fixed to the elastic insertion member 551, coaxial with the twist needle loading hole 522 in the twist needle insertion state, and located on the side of the needle sheath placement platform 51 away from the crimping member 53. The elastic insertion member 551 moves, driving the push block 552 to push the needle sheath in the needle sheath placement platform 51 into the crimping member 53. The push block 552 and the elastic insertion member 551 are designed to be replaceable, and different shapes of push blocks 552 can be replaced according to the shape of the needle sheath to accommodate needle sheaths of different shapes.

[0046] In addition, to facilitate the recovery of crimped twist needles, the crimping mechanism 5 also includes a recovery box 56, located below the needle sleeve insertion component 55. The recovery box 56 is an open-top box with a storage space formed within it. After crimping is completed, the elastic insertion member 551 retracts, and the twist needle insertion drive member drives the telescopic member 541 to further extend. The ejector pin 542 ejects the crimped twist needles from the crimping component 53 and pushes them off the needle sleeve placement platform 51 into the recovery box 56, facilitating centralized recovery by staff.

[0047] When in use, the needle sleeve feeding mechanism 2 feeds the needle sleeve into the cross-shaped groove 511, and the twist needle feeding mechanism 3 feeds the twist needle into the twist needle loading hole 522 in the twist needle loading state. The movable end of the translation driver shrinks to the minimum state, and the twist needle loading hole 522 is aligned with the center position of the fixed ring 531. The needle sleeve pushing-in driving member drives the elastic pushing-in member 551 to move, and pushes the needle sleeve in the needle sleeve placement platform 51 into the crimping component 53. Then, the twist needle pushing-in driving member drives the telescopic The part 541 moves, and the ejector pin 542 pushes the twist needle in the twist needle loading hole 522 into the crimping component 53, and the needle sleeve is sleeved on the twist needle. The crimping surfaces of the crimping assembly 532 move toward each other to crimp the twist needle with the needle sleeve. After the crimping is completed, the elastic ejector pin 551 retracts, and the twist needle ejection driving member drives the telescopic part 541 to further extend. The ejector pin 542 ejects the crimped twist needle from the crimping component 53, and the crimped twist needle is recovered by the staff.

[0048] The present invention has the following beneficial effects: It provides a compatible twist needle crimping device, wherein the needle sleeve placement table is provided with a cross-shaped groove for placing the needle sleeve and a replaceable top block, so that the device can adapt to needle sleeves of various shapes, such as straight, cross, L, T, etc., so that the entire twist needle crimping device can crimp needle sleeves of various shapes with twist needles, making it more compatible.
