[0030] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0031] A puncture needle correction station, such as Figures 1-11 As shown, it includes a material base 1, a positioning component 3, a detection component 4 and a correction component 5. The material base 1 is used to support the clamp of the puncture needle 2. The positioning component 3 and the correction component 5 are located on one side of the material base 1, and the detection component 4 is located on the other side of the material base 1.

[0032] The positioning component 3 and the correction component 5 are both installed on the mounting frame 6, and the mounting frame 6 is slidably set on the base 7. The base 7 is provided with a driving component 8 for driving the mounting frame 6 to move, and the output end of the driving component 8 is connected to the mounting frame 6. In this embodiment, the driving component 8 adopts a cylinder. As other solutions, an oil cylinder or an electric cylinder can also be used. The mounting frame 6 is slidably set on the base 7 through the cooperation of the slider and the slide rail. Specifically, a slide rail is provided on the base 7, and a slider is provided on the mounting frame 6. The slider is slidably connected to the slide rail. It should be noted that the mounting frame 6 is driven to slide by the driving component 8, so that the positioning component 3 and the correction component 5 are close to or away from the puncture needle 2 on the material holder 1.

[0033] The detection component 4 and the correction component 5 are both connected to the control terminal. In this embodiment, the control terminal is a PLC control terminal.

[0034] The positioning assembly 3 is used to position the puncture needle 2 on the material holder 1. Specifically, in this embodiment, the positioning assembly 3 includes a finger cylinder 31 and at least two clamps 32. The output end of the finger cylinder 31 is connected to the two clamps 32. The two clamps 32 can cooperate to form a clamping port 9 for movably clamping the needle head of the puncture needle 2. A clamping groove 12 is provided on each of the two clamps 32. The two clamping grooves 12 can be spliced together to form the clamping port 9. Both clamping grooves 12 are V-shaped.

[0035] It should be noted that the two clamping jaws 32 are driven to move closer to or away from each other by the finger cylinder 31. The two clamping jaws 32 move closer to each other so that the two clamping grooves 12 are spliced together to form a clamping opening 9. The needle head of the puncture needle 2 is located in the clamping opening 9. The clamping opening 9 restricts the needle head of the puncture needle 2, thereby achieving concentric positioning of the puncture needle 2 in the vertical direction and ensuring the stability of the puncture needle 2.

[0036] It should be further explained that the two clamping grooves 12 are both V-shaped, so as to be adaptable to the needle heads of puncture needles 2 of different specifications and sizes. As another solution, the two clamping grooves 12 can also be U-shaped.

[0037] One of the jaws 32 is threadedly connected to a limiting member 13, and the end of the limiting member 13 abuts against the side wall of the other jaw 32. Preferably, the limiting member 13 adopts a limiting screw. The user can change the position of the limiting member 13 by rotating the limiting member 13, thereby effectively limiting the minimum opening distance between the two jaws 32, avoiding the opening distance between the two jaws 32 being too small, thereby avoiding damage to the needle head of the puncture needle 2 during clamping.

[0038] The detection component 4 is used to detect the blade position of the needle head of the puncture needle 2 and transmit it to the control terminal. In this embodiment, the detection component 4 includes a camera 41, which is used to collect the image of the puncture needle 2 on the material holder 1. The positioning component 3 is provided with a light source board 10 corresponding to the camera 41. Specifically, the light source board 10 is installed on one of the clamps 32. As the clamp 32 moves and approaches the puncture needle 2 on the material holder 1, the light source board 10 moves to the puncture needle and cooperates with the camera 41 to effectively complete the collection of the image of the puncture needle 2 on the material holder 1.

[0039] A fill light 14 is provided on the base 7 , and the fill light 14 corresponds to the light source board 10 . The fill light 14 cooperates with the light source board 10 to make the image of the blade surface of the puncture needle 2 captured by the camera 41 clearer.

[0040] The correction component 5 rotates the needle head of the puncture needle 2 according to the blade position of the needle head of the puncture needle 2 detected by the detection component 4.

[0041] Specifically, the correction component 5 includes a driving member 51, a swinging member 52 and a clamping member 53. The clamping member 53 is used to clamp the outer wall of the needle head of the puncture needle 2. The swinging member 52 is used to drive the clamping member 53 to swing so that it is close to or away from the needle head of the puncture needle 2. The driving member 51 is used to drive the clamping member 53 to move along the tangential direction of the needle head of the puncture needle 2, so that the clamping member 53 drives the needle head of the puncture needle 2 to rotate.

[0042] The clamping member 53 includes two mounting blocks 531 and two clamping blocks 532. The middle portions of the two mounting blocks 531 are rotatably mounted on the sides of the two slides 11. The two clamping blocks 532 are mounted on the two mounting blocks 531, respectively. Both clamping blocks 532 are capable of abutting against the outer side walls of the puncture needle 2 and are made of a flexible material. In this embodiment, the end surfaces of the two clamping blocks 532 that clamp the puncture needle 2 are provided with a layer of a flexible sheet such as rubber or silicone. The two clamping blocks 532 can be made of conventional plastic or metal to prevent damage to the puncture needle 2 when the clamping blocks 532 abut against the needle.

[0043] The swinging member 52 includes two driving cylinders 521 and two joints 522. The two driving cylinders 521 are rotatably arranged on the two slides 11 respectively. The output ends of the two driving cylinders 521 are respectively connected to the two joints 522, and the two joints 522 are respectively rotatably connected to the two mounting seats 531. The driving cylinder 521 is used to drive the joint 522 to move so that the mounting seat 531 and the clamping block 532 swing. The driving cylinder 521 drives the joint 522 to move, and the joint 522 drives the mounting seat 531 to swing at its transition point with the slide 11. The mounting seat 531 drives the clamping block 532 to swing, so that the clamping block 532 approaches or moves away from the needle head of the puncture needle 2, so that the clamping block 532 can abut against the outer wall of the needle head of the puncture needle 2.

[0044] The driving member 51 includes a rotation driving source 511 and a linkage block 512. The output end of the rotation driving source 511 is connected to the linkage block 512. The two ends of the linkage block 512 are respectively connected to the two slides 11. Specifically, bolt needle bearings are provided at both ends of the linkage block 512. The two bolt needle bearings are connected to the two slides 11. The two slides 11 are slidably arranged on the mounting frame 6 through corresponding slide rails and sliders. Specifically, the slide rail is arranged on the mounting frame 6, and the slider is arranged on the slider 11. The slider is slidably connected to the slide rail. The rotation driving source 511 is preferably a motor. As another solution, other driving sources with a rotation function can also be used. The output end of the rotation driving source 511 rotates to drive the linkage block 512 to rotate. The two ends of the linkage block 512 respectively drive the two slides 11 to move in opposite directions. The two slides 11 drive the corresponding mounting seat 531 and the clamping block 532 to move along the tangential direction of the needle head of the puncture needle 2. The friction between the clamping block 532 and the needle head of the puncture needle 2 drives the needle head of the puncture needle 2 to rotate.

[0045] A driving cylinder 2 15 and a driving cylinder 3 16 are provided on the base 7. The output end of the driving cylinder 2 15 is connected to the clamping seat 17. The driving cylinder 2 15 and the clamping seat 1 17 are located on one side of the material base 1. The driving cylinder 2 15 is used to drive the clamping seat 17 to move closer to or away from the material base 1. The output end of the driving cylinder 3 16 is connected to the clamping seat 2 18. The driving cylinder 3 16 and the clamping seat 2 18 are located on the other side of the material base 1. The driving cylinder 3 16 is used to drive the clamping seat 2 18 to move closer to or away from the material base 1.

[0046] At least one positioning groove 20 is provided on the material holder 1. Preferably, there are several positioning grooves 20 and they are distributed along the length direction of the material holder 1. A positioning block 19 is provided on the clamping seat 17. The positioning block 19 can extend into the positioning groove 20. The clamping seat 17 is driven by the driving cylinder 2 15 to approach the material holder 1, so that the positioning block 19 extends into the positioning groove 20. The positioning block 19 cooperates with the positioning groove 20 to achieve the positioning of the material holder 1, ensuring that the position of the material holder 1 can remain stable during the process of detecting and correcting the needle head of the puncture needle 2. After completing the detection and correction of the needle head of the puncture needle 2, the driving cylinder 2 15 drives the clamping seat 17 away from the material holder 1, and the positioning block 19 disengages from the positioning groove 20.

[0047] The clamping seat 17 can cooperate with the clamping seat 2 18 to clamp the needle seat of the puncture needle 2. It should be noted that before detecting and correcting the needle head of the puncture needle 2, the clamping seat 17 is driven to approach the material seat 1 by driving the cylinder 2 15, and the clamping seat 2 18 is driven to approach the material seat 1 by driving the cylinder 3 16, so that the clamping seat 17 cooperates with the clamping seat 2 18 to clamp the needle seat of the puncture needle 2, thereby further ensuring the stability of the puncture needle 2.

[0048] The working principle of this utility model is as follows:

[0049] First, the cylinder 2 15 is driven to drive the clamping seat 1 17 close to the material seat 1, so that the positioning block 19 extends into the positioning groove 20, and the cylinder 3 16 is driven to drive the clamping seat 2 18 close to the material seat 1. The clamping seat 17 cooperates with the clamping seat 2 18 to clamp the needle seat of the puncture needle 2. Then the driving component 8 drives the mounting frame 6 to slide, so that the positioning component 3 and the correction component 5 are close to the puncture needle 2 on the material seat 1. At this time, the finger cylinder 31 drives the two clamping claws 32 to approach each other so that the needle head of the puncture needle 2 is clamped in the clamping port 9. At the same time, the camera 41 collects the image of the puncture needle 2 on the material seat 1 and transmits it to the control terminal to detect the needle of the puncture needle 2. The blade position of the head, and then the two driving cylinders 521 drive the corresponding joints 522 to move respectively, and the joints 522 drive the corresponding mounting seat 531 and the clamping block 532 to swing, so that the two clamping blocks 532 are both against the outer wall of the needle head of the puncture needle 2. Finally, according to the blade position of the needle head of the puncture needle 2, the rotating driving source 511 drives the linkage block 512 to rotate forward or reverse, and the linkage block 512 drives the two slides 11 and the corresponding mounting seat 531 and the clamping block 532 to move along the tangential direction of the needle head of the puncture needle 2, and the clamping block 532 drives the puncture needle 2 to rotate forward or reverse, thereby adjusting the blade position of the needle head of the puncture needle 2.

[0050] It should be noted that in the process of positioning the puncture needle 2 and correcting the position of the blade of the needle head of the puncture needle 2, all components avoid the blade of the needle head of the puncture needle 2 and do not need to directly contact the needle head of the puncture needle 2, thereby avoiding damage such as barbs, burrs, and bluntness on the blade of the needle head of the puncture needle 2, thereby avoiding affecting the sharpness and puncture force of the blade of the puncture needle 2.
