[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] See also Figures 1 to 13 A method for selecting a needle for a glove machine according to an embodiment of the present invention comprises the following steps: Provided are a needle selector 1 and a needle plate assembly 2. The needle plate assembly 2 is arranged above the needle selector 1. The needle selector 1 is provided with a plurality of magnetic bar assemblies 11. The needle plate assembly 2 is provided with a plurality of spring needles 21 corresponding to the plurality of magnetic bar assemblies 11. The magnetic bar assembly 11 includes a magnetic member with one end being an N pole and the other end being an S pole, and an energized coil arranged on the magnetic member. The target spring pin 21 is adsorbed by the magnetic member, and the target spring pin 21 is adsorbed to the N end and the S end of the magnetic member at the same time, and a closed magnetic flux line is formed in the magnetic member and the target spring pin 21, so that the target spring pin 21 stops at the designated position; By energizing the energizing coil, the magnetic element is demagnetized, so that the magnetic element releases the adsorbed target spring pin 21, and the target spring pin 21 is reset under the action of its own elastic force.

[0021] In the needle selection method, a needle selector 1 and a needle plate assembly 2 are provided, and the needle plate assembly 2 is arranged above the needle selector 1. A plurality of magnetic bar assemblies 11 are arranged in the needle selector 1, and a plurality of spring needles 21 are arranged in the needle plate assembly 2, the number of the spring needles 21 is the same as the number of the magnetic bar assemblies 11, and the positions of the plurality of spring needles 21 correspond one to one with the positions of the plurality of magnetic bar assemblies 11.

[0022] In the needle selection method, a needle selector 1 is provided, and its magnetic bar assembly 11 includes a magnetic piece, one end of which is an N pole and the other end is an S pole. When selecting a needle, the target spring needle 21 is adsorbed by the magnetic attraction force generated by the magnetic piece, and the target spring needle 21 is adsorbed at the N pole and the S pole of the magnetic piece at the same time, so that the target spring needle 21 stops at a designated position. Due to the direction of the magnetic flux lines of the magnet, it is from the N pole to the S pole outside the magnet and from the S pole to the N pole inside the magnet. In the prior art, for a single spring needle 21, the magnetic bars of the needle selector 1 used are all of the same magnetic pole.

[0023] Therefore, outside the magnetic bar, the magnetic flux lines are propagated from the N pole to the S pole in the air, and the magnetic flux lines propagating in the air have a stray loop and a large energy loss, which can easily interfere with the magnetic field of the surrounding magnetic bars and reduce the adsorption force of the magnetic bar on the corresponding spring needle 21, which may lead to needle selection errors, resulting in weaving errors and affecting production efficiency.

[0024] In the present application, since one end of the magnetic member is an N pole and the other end is an S pole, the direction of the magnetic flux lines of the magnetic member is from the N pole to the S pole outside the magnetic member, that is, outside the magnetic member, the magnetic flux lines are transmitted from the N pole of the magnetic member to the S pole of the magnetic member in the air. When the magnetic member simultaneously adsorbs the target spring needle 21 to the N pole and the S pole of the magnetic member, the target spring needle 21 conducts the N pole and the S pole of the magnetic member, thereby forming a closed magnetic flux line in the magnetic member and the target spring needle 21.

[0025] In this embodiment, the spring pin 21 is made of soft magnetic material. Since air is a non-magnetic medium, its magnetic resistance is much greater than that of soft magnetic material, and similar to electric current, magnetic flux lines always take the path with the smallest magnetic resistance (maximum magnetic permeability), so outside the magnetic element, most of the magnetic flux lines are transmitted from the N pole to the S pole in the spring pin 21, thereby forming a closed magnetic flux line in the magnetic element and the target spring pin 21.

[0026] On the one hand, it can prevent the magnetic flux lines propagating outside the magnetic component from being scattered, thereby reducing the magnetic field interference with the surrounding magnetic components; on the other hand, since the magnetic resistance of the spring needle 21 is much smaller than the magnetic resistance of the air, the energy loss of the magnetic flux lines propagating in the spring needle 21 is small, thereby enhancing the adsorption force of the magnetic component on the target spring needle 21, thereby ensuring the accuracy of needle selection and improving production efficiency.

[0027] In the needle selection method, the needle selector 1 provided, the magnetic bar assembly 11 of which also includes a power-on coil. When the needle is selected, the power-on coil is energized, and the magnetic field formed in the power-on coil has a magnetic flux line direction opposite to the internal magnetic flux line direction of the magnetic member. Therefore, the magnetic field formed in the power-on coil and the magnetic field of the magnetic member cancel each other out, thereby reducing the magnetic field strength of the magnetic member and achieving demagnetization of the magnetic member.

[0028] When the magnetic attraction of the magnetic element to the target spring pin 21 is smaller than the elastic force of the target spring pin 21 to restore its own deformation, the magnetic element releases the attracted target spring pin 21, so that the target spring pin 21 is reset under the action of its own elastic force, thereby realizing the needle selection of the glove machine.

[0029] In one embodiment, initially, the power-on coil is energized, and the magnetic member does not adsorb the target spring needle 21, and the target spring needle 21 is in a non-working position; when selecting the needle, the power-on coil is de-energized, and the magnetic member adsorbs the target spring needle 21, so that the target spring needle 21 moves from the non-working position to the working position to perform the knitting operation, that is, in the above method, the target spring needle 21 stops at the designated position, and the designated position is the working position; after the work is completed, the power-on coil is energized again, and the magnetic member releases the target spring needle 21, so that the target spring needle 21 returns to the non-working position, waiting for the next knitting operation.

[0030] In another embodiment, initially, the energized coil is powered off, and the magnetic member absorbs the target spring needle 21. At this time, the target spring needle 21 is in a non-working position, that is, in the above method, the target spring needle 21 is stopped at a designated position, and the designated position is a non-working position; when selecting needles, the energized coil is energized, and the magnetic member releases the target spring needle 21, so that the target spring needle 21 moves from the non-working position to the working position to perform a knitting operation; after the work is completed, the energized coil is powered off again, and the magnetic member absorbs the target spring needle 21, so that the target spring needle 21 returns to the non-working position, waiting for the next knitting operation.

[0031] In this embodiment, the steps of providing a needle selector 1 include: A needle selector seat 12 is provided in the needle selector 1, and a plurality of magnetic bar assemblies 11 are arranged in at least two rows on the needle selector seat 12, and the magnetic bar assemblies 11 arranged in two adjacent rows are staggered.

[0032] In the present needle selection method, the provided needle selector 1 includes a needle selection seat 12, and a plurality of magnetic bar assemblies 11 are arranged in at least two rows on the needle selection seat 12, and the plurality of magnetic bar assemblies 11 arranged in two adjacent rows are staggered in sequence, so that the plurality of magnetic bar assemblies 11 can adsorb the corresponding spring needles 21, or release the corresponding spring needles 21, and in the process of the plurality of magnetic bar assemblies 11 adsorbing or releasing the corresponding spring needles 21, the movement trajectories of all the spring needles 21 do not overlap, thereby preventing mutual interference between the spring needles 21, thereby ensuring the accuracy of needle selection and improving production efficiency.

[0033] In this embodiment, the steps of providing a needle plate assembly 2 include: A first support plate 22 and a second support plate 23 are provided in the needle plate assembly 2, and a rotating shaft 24 is provided between the first support plate 22 and the second support plate 23. The two ends of the rotating shaft 24 are fixed by the first support plate 22 and the second support plate 23 respectively, and the rotating shaft 24 is mounted on one side of the needle selection seat 12, so that a plurality of spring needles 21 are arranged in sequence on the rotating shaft 24 and are rotatably connected to the rotating shaft 24.

[0034] In the present needle selection method, the provided needle plate assembly 2 includes a first support plate 22, a second support plate 23 and a rotating shaft 24. The first support plate 22 and the second support plate 23 are arranged relatively spaced apart, and the rotating shaft 24 is mounted between the first support plate 22 and the second support plate 23, so that the two ends of the rotating shaft 24 are respectively fixed by the first support plate 22 and the second support plate 23, thereby realizing the fixation of the rotating shaft 24.

[0035] A plurality of spring pins 21 are arranged side by side on the rotating shaft 24, so that the positions of the plurality of spring pins 21 are fixed by the rotating shaft 24. As described above, when the magnetic member attracts or releases the target spring pin 21, the target spring pin 21 is displaced, so that the target spring pin 21 is switched between the working position and the non-working position.

[0036] Therefore, in the present application, when a plurality of spring pins 21 are arranged side by side on the rotating shaft 24 , they are rotatably connected to the rotating shaft 24 , so that when the magnetic member adsorbs the target spring pin 21 , the target spring pin 21 rotates around the rotating shaft 24 and generates elastic deformation.

[0037] When the magnetic member releases the target spring needle 21, the target spring needle 21 rotates in the opposite direction around the rotating shaft 24 under the elastic force of restoring its own deformation, so that the target spring needle 21 returns to the initial position, and then the target spring needle 21 switches between the working position and the non-working position, thereby realizing the needle selection of the glove machine.

[0038] Specifically, in this embodiment, the spring needle 21 includes an adsorption portion 2111 and a deformation portion 2112. A rotating hole 2113 is provided at one end of the adsorption portion 2111 away from the needle selection seat 12. The rotating shaft 24 simultaneously penetrates the rotating holes 2113 of multiple adsorption portions 2111, so that the adsorption portions 2111 of multiple spring needles 21 are simultaneously rotatably connected to the rotating shaft 24, and the deformation portion 2112 is provided at the bottom of the adsorption portion 2111.

[0039] In this needle selection method, when the magnetic component adsorbs the target spring needle 21, the magnetic attraction force generated by the N extreme end and the S extreme end of the magnetic component adsorbs the end of the adsorption portion 2111 close to the needle selection seat 12 at the same time, so that the adsorption portion 2111 rotates around the rotating axis 24, and at the same time the deformation portion 2112 is compressed and deformed, so that the adsorption portion 2111 stops at the designated work position.

[0040] When the magnetic attraction generated by the N and S extreme ends of the magnetic element decreases or disappears, the magnetic element loosens the end of the adsorption portion 2111 close to the needle selection seat 12, and under the elastic force of the deformation portion 2112 to restore its own deformation, the adsorption portion 2111 rotates in the opposite direction around the rotating shaft 24 to reset, so that the adsorption portion 2111 of the target spring needle 21 is switched between the working position and the non-working position, thereby realizing the needle selection of the glove machine.

[0041] In this embodiment, the needle selector 12 includes a first seat body 121 and a second seat body 122 that are assembled with each other, a first half cavity is provided in the first seat body 121, and a second half cavity is provided in the second seat body 122. A plurality of magnetic bar assemblies 11 are arranged in at least two rows on the needle selector 12, and the magnetic bar assemblies 11 arranged in two adjacent rows are staggered, including: The plurality of magnetic bar assemblies 11 in the first row are arranged in the first half cavity, and the plurality of magnetic bar assemblies 11 in the second row are arranged in the second half cavity, so that the plurality of magnetic bar assemblies 11 in the first row and the plurality of magnetic bar assemblies 11 in the second row are arranged in a staggered manner.

[0042] In the needle selection method, the needle selection seat 12 is composed of a first seat body 121 and a second seat body 122. A first half cavity is provided in the first seat body 121, and a second half cavity is provided in the second seat body 122. When multiple magnetic bar assemblies 11 are arranged on the needle selection seat 12, the first row of magnetic bar assemblies 11 are arranged in the first half cavity, and the second row of magnetic bar assemblies 11 are arranged in the second half cavity, and the first row of magnetic bar assemblies 11 arranged in the first half cavity are staggered with the second row of magnetic bar assemblies 11 arranged in the second half cavity, so that when the first row of magnetic bar assemblies 11 and the second row of magnetic bar assemblies 11 adsorb or release the corresponding spring needles 21, there will be no mutual interference between the spring needles 21.

[0043] In the previous embodiment, it is mentioned that the plurality of magnetic bar assemblies 11 are arranged in at least two rows on the needle selection seat 12, and the plurality of magnetic bar assemblies 11 arranged in two adjacent rows are arranged alternately in sequence. Therefore, it can be foreseen that in actual implementation, the first half cavity of the first seat body 121 and the second half cavity of the second seat body 122 are not limited to being provided with one row of magnetic bar assemblies 11, but multiple rows of magnetic bar assemblies 11 can also be provided.

[0044] It is worth noting that: when multiple rows of magnetic bar assemblies 11 are set in the first half cavity and the second half cavity, the multiple rows of magnetic bar assemblies 11 in the first half cavity have the same dislocation direction, and when the first seat body 121 and the second seat body 122 are spliced, the two adjacent rows of magnetic bar assemblies 11 at the junction of the first half cavity and the second half cavity are also dislocated, and the dislocation direction is also consistent with the dislocation direction of the multiple rows of magnetic bar assemblies 11 in the first half cavity, and the remaining multiple rows of magnetic bar assemblies 11 in the second half cavity are all consistent with the dislocation direction of a row of magnetic bar assemblies 11 at the junction, thereby ensuring that the movement trajectories of all spring needles 21 do not overlap.

[0045] Furthermore, in the present application, a plurality of magnetic rod limiting grooves 1211 are provided at the bottom of the first half cavity and the second half cavity. When the first row of magnetic rod assemblies 11 are provided in the first half cavity, the plurality of magnetic rod limiting grooves 1211 at the bottom of the first half cavity respectively limit the bottom of the plurality of magnetic rod assemblies 11 in the first row; when the second row of magnetic rod assemblies 11 are provided in the second half cavity, the plurality of magnetic rod limiting grooves 1211 at the bottom of the second half cavity respectively limit the bottom of the plurality of magnetic rod assemblies 11 in the second row.

[0046] A plurality of magnetic rod extension openings 1212 are provided at the top of the first half cavity and the second half cavity. When the first row of magnetic rod assemblies 11 are arranged in the first half cavity, the tops of the plurality of magnetic rod assemblies 11 in the first row extend out through the plurality of magnetic rod extension openings 1212 respectively.

[0047] When the second row of magnetic bar assemblies 11 are arranged in the second half cavity, the tops of the plurality of magnetic bar assemblies 11 in the second row extend out through the plurality of magnetic bar extension openings 1212 respectively, so that the tops of the first row of magnetic bar assemblies 11 in the first half cavity and the tops of the second row of magnetic bar assemblies 11 in the second half cavity can both adsorb their corresponding spring pins 21 or release their corresponding spring pins 21, thereby realizing the needle selection of the glove machine.

[0048] In the present application, a plurality of magnetic bar limiting grooves 1211 arranged at the bottom of the first half cavity are staggered with a plurality of magnetic bar limiting grooves 1211 arranged at the bottom of the second half cavity; a plurality of magnetic bar extension openings 1212 arranged at the top of the first half cavity are staggered with a plurality of magnetic bar extension openings 1212 arranged at the top of the second half cavity, thereby making the first row of magnetic bar assemblies 11 arranged in the first half cavity staggered with the second row of magnetic bar assemblies 11 arranged in the second half cavity.

[0049] Further, in the present application, one end of the multiple magnetic bar extension openings 1212 arranged at the top of the first half cavity and the second half cavity is open, and one end of the multiple magnetic bar limiting grooves 1211 arranged at the bottom of the first half cavity and the second half cavity is open.

[0050] In the present needle selection method, when installing the first row of magnetic bar assemblies 11 in the first seat body 121 and the second row of magnetic bar assemblies 11 in the second seat body 122, the top of the magnetic bar assembly 11 is slidably inserted into the magnetic bar extension port 1212 through the opening of the magnetic bar extension port 1212, and at the same time, the bottom of the magnetic bar assembly 11 is slidably inserted into the magnetic bar limiting groove 1211 through the opening of the magnetic bar limiting groove 1211, thereby making the installation of the first row of magnetic bar assemblies 11 in the first seat body 121 and the installation of the second row of magnetic bar assemblies 11 in the second seat body 122 simpler and more convenient, thereby making the implementation of the present needle selection method simpler and more convenient.

[0051] Further, in this embodiment, the plurality of spring pins 21 include a plurality of long pins 211 and a plurality of short pins 212, and the plurality of long pins 211 and the plurality of short pins 212 are alternately arranged on the rotating shaft 24, and the target spring pin 21 is adsorbed by the magnetic member, including: The plurality of magnetic bar assemblies 11 in the first row adsorb the plurality of short needles 212 , and the plurality of magnetic bar assemblies 11 in the second row adsorb the plurality of long needles 211 , respectively.

[0052] According to the previous records, the end of the spring needle 21 away from the needle selection seat 12 is sleeved on the rotating shaft 24, so the rotating shaft 24 fixes the position of the end of the spring needle 21 away from the needle selection seat 12. In the present application, the needle selection seat 12 is composed of a first seat body 121 and a second seat body 122. Therefore, the rotating shaft 24 is arranged on one side of the first seat body 121 or the second seat body 122. The following description will be taken as an example in which the rotating shaft 24 is arranged on one side of the first seat body 121.

[0053] Since the end of the spring pin 21 away from the first seat body 121 is sleeved on the rotating shaft 24 through the rotating hole 2113, the spring pin 21 is rotatably connected to the rotating shaft 24, and the rotating shaft 24 fixes the position of the end of the spring pin 21 away from the first seat body 121.

[0054] In the present application, multiple magnetic bar assemblies 11 are arranged in at least two rows on the needle selection seat 12. Therefore, when the rotating shaft 24 is set on one side of the needle selection seat 12, there is a difference in the distance between it and each row of magnetic bar assemblies 11. If all spring needles 21 are set to the same length, it is possible that a row of magnetic bar assemblies 11 far away from the rotating shaft 24 cannot adsorb the corresponding spring needles 21.

[0055] An example is given in which two rows of magnetic bar assemblies 11 are arranged on the needle selection seat 12, wherein the first row of magnetic bar assemblies 11 are arranged in the first half cavity of the first seat body 121, and the second row of magnetic bar assemblies 11 are arranged in the second half cavity of the second seat body 122. In this embodiment, since the rotation axis 24 is arranged on one side of the first seat body 121, it can be foreseen that the distance between the second row of magnetic bar assemblies 11 and the rotation axis 24 is greater than the distance between the first row of magnetic bar assemblies 11 and the rotation axis 24.

[0056] Therefore, in the needle selection method, the multiple spring needles 21 include multiple short needles 212 and multiple long needles 211. When the rotating shaft 24 fixes one end of the multiple long needles 211 and the multiple short needles 212 away from the first base body 121, the multiple short needles 212 extend to the top of the first row of magnetic bar assemblies 11, and the multiple long needles 211 extend to the top of the second row of magnetic bar assemblies 11.

[0057] Since the first row of magnetic bar assemblies 11 and the second row of magnetic bar assemblies 11 are staggered, the multiple short needles 212 and the multiple long needles 211 are staggered, so that the multiple magnetic bar assemblies 11 in the first row can absorb or release the multiple short needles 212 respectively, and the multiple magnetic bar assemblies 11 in the second row can absorb or release the multiple long needles 211 respectively, thereby ensuring that the multiple magnetic bar assemblies 11 arranged on the needle selection seat 12 can absorb or release the corresponding spring needles 21, thereby realizing the needle selection of the glove machine.

[0058] In this embodiment, the magnetic member includes a first magnetic bar 111 and a second magnetic bar 112 which are arranged at intervals, and a permanent magnet 116 which is arranged between the first magnetic bar 111 and the second magnetic bar 112. The first magnetic bar 111 is aligned with the N pole of the permanent magnet 116, and the second magnetic bar 112 is aligned with the S pole of the permanent magnet 116. The target spring needle 21 is adsorbed by the magnetic bar assembly 11, and the target spring needle 21 is simultaneously adsorbed on the N pole and the S pole of the magnetic bar assembly 11, including: The first magnetic bar 111 and the second magnetic bar 112 are magnetized by the permanent magnet 116 , and magnetic attraction is generated at the top of the first magnetic bar 111 and the top of the second magnetic bar 112 , so that the top of the first magnetic bar 111 and the top of the second magnetic bar 112 simultaneously adsorb the target spring pin 21 .

[0059] In the present application, the magnetic member includes a first magnetic bar 111, a second magnetic bar 112 and a permanent magnet 116. The first magnetic bar 111 and the second magnetic bar 112 are arranged at intervals, and the permanent magnet 116 is arranged between the first magnetic bar 111 and the second magnetic bar 112. Since the first magnetic bar 111 is aligned with the N pole of the permanent magnet 116, and the second magnetic bar 112 is aligned with the S pole of the permanent magnet 116, the first magnetic bar 111 and the second magnetic bar 112 are magnetized by magnetizing through the permanent magnet 116, and the top of the first magnetic bar 111 is the N pole, and the top of the second magnetic bar 112 is the S pole.

[0060] After the first magnetic bar 111 and the second magnetic bar 112 are magnetized by the permanent magnet 116, it is equivalent to that the first magnetic bar 111 extends the N pole of the permanent magnet 116, and the second magnetic bar 112 extends the S pole of the permanent magnet 116, that is, the magnetic piece forms an integral magnet through the first magnetic bar 111, the permanent magnet 116 and the second magnetic bar 112, the first magnetic bar 111 is the N pole of the magnetic piece, the top of the first magnetic bar 111 is the N end of the magnetic piece, the second magnetic bar 112 is the S pole of the magnetic piece, and the top of the second magnetic bar 112 is the S end of the magnetic piece.

[0061] In this needle selection method, the target spring needle 21 is adsorbed by the magnetic bar assembly 11, and the target spring needle 21 is simultaneously adsorbed on the N end and the S end of the magnetic bar assembly 11. The first magnetic bar 111 and the second magnetic bar 112 are magnetized by the permanent magnet 116, and a magnetic attraction force is generated at the top of the first magnetic bar 111 and the top of the second magnetic bar 112, so that the top of the first magnetic bar 111 and the top of the second magnetic bar 112 simultaneously adsorb the target spring needle 21.

[0062] Outside the magnetic member, the magnetic flux lines are propagated in the air from the top of the first magnetic bar 111 to the top of the second magnetic bar 112. When the top of the first magnetic bar 111 and the top of the second magnetic bar 112 simultaneously adsorb the target spring needle 21, the target spring needle 21 connects the top of the first magnetic bar 111 with the top of the second magnetic bar 112, thereby forming a closed magnetic flux line in the first magnetic bar 111, the target spring needle 21, the second magnetic bar 112 and the permanent magnet.

[0063] On the one hand, it can prevent the magnetic flux lines propagating outside the first magnetic bar 111 and the second magnetic bar 112 from being scattered, thereby reducing the magnetic field interference with the surrounding magnetic parts; on the other hand, the energy loss of the magnetic flux lines propagating in the target spring needle 21 is small, thereby enhancing the adsorption force of the first magnetic bar 111 and the second magnetic bar 112 on the target spring needle 21, thereby ensuring the accuracy of needle selection and improving production efficiency.

[0064] Furthermore, in this embodiment, the magnetic member further includes a magnetic bar base 115, the first magnetic bar 111 is aligned with the N pole of the permanent magnet 116, and the second magnetic bar 112 is aligned with the S pole of the permanent magnet 116, including: The bottom of the first magnetic bar 111 is inserted into the first fixed cavity 1151 of the magnetic bar base 115, the bottom of the second magnetic bar 112 is inserted into the second fixed cavity 1152 of the magnetic bar base 115, the permanent magnet 116 is arranged in the third fixed cavity 1153 of the magnetic bar base 115, the first fixed cavity 1151 and the second fixed cavity 1152 are arranged at intervals, the third fixed cavity 1153 is arranged between the first fixed cavity 1151 and the second fixed cavity 1152, and one end of the third fixed cavity 1153 is provided with a first opening connected to the first fixed cavity 1151, and the other end is provided with a second opening connected to the second fixed cavity 1152, so that the bottom end of the first magnetic bar 111 is in contact with the N pole of the magnet through the first opening, and the bottom end of the second magnetic bar 112 is in contact with the S pole of the permanent magnet 116 through the second opening.

[0065] In the present application, the magnetic member also includes a magnetic rod base 115, on which a first fixed cavity 1151, a second fixed cavity 1152 and a third fixed cavity 1153 are provided. The first fixed cavity 1151 and the second fixed cavity 1152 are spaced apart, and the third fixed cavity 1153 is provided between the first fixed cavity 1151 and the second fixed cavity 1152.

[0066] A first opening is provided at one end of the third fixed cavity 1153 , and the third fixed cavity 1153 is connected to the first fixed cavity 1151 through the first opening; a second opening is provided at the other end of the third fixed cavity 1153 , and the third fixed cavity 1153 is connected to the second fixed cavity 1152 through the second opening.

[0067] In the present needle selection method, when installing the first magnetic bar 111, the second magnetic bar 112 and the permanent magnet 116 on the magnetic bar base 115, the permanent magnet 116 is set in the third fixed cavity 1153, and then the bottom of the first magnetic bar 111 is inserted into the first fixed cavity 1151, and the bottom of the second magnetic bar 112 is inserted into the second fixed cavity 1152, so that the first magnetic bar 111 is fixed by the first fixed cavity 1151, the second magnetic bar 112 is fixed by the second fixed cavity 1152, and the permanent magnet 116 is fixed by the third fixed cavity 1153, so that the first magnetic bar 111 and the second magnetic bar 112 are spaced apart on the magnetic bar base 115, and the permanent magnet 116 is set between the first magnetic bar 111 and the second magnetic bar 112.

[0068] Since the N pole and S pole of the permanent magnet 116 are respectively arranged at the two ends of the permanent magnet 116, the bottom of the first magnetic bar 111 is inserted into the first fixed cavity 1151, and the bottom of the second magnetic bar 112 is inserted into the second fixed cavity 1152. When the permanent magnet 116 is arranged in the third fixed cavity 1153, the N pole of the permanent magnet 116 is at one end of the third fixed cavity 1153, and fits with the bottom end of the first magnetic bar 111 through the first opening; the S pole of the permanent magnet 116 is at the other end of the third fixed cavity 1153, and fits with the bottom of the second magnetic bar 112 through the second opening, so that the magnetic piece forms a U-shaped magnet.

[0069] Therefore, when the target spring needle 21 is simultaneously adsorbed by the first magnetic bar 111 and the second magnetic bar 112, the target spring needle 21 conducts the N pole and the S pole of the U-shaped magnet, so that most of the magnetic flux lines are transmitted from the target spring needle 21, which can not only increase the adsorption force of the magnetic component on the target spring needle 21, but also reduce the magnetic field interference between multiple magnetic components, thereby ensuring the accuracy of needle selection and improving production efficiency.

[0070] Furthermore, in the present application, a first contact surface 1111 is provided at the top of the first magnetic bar 111, and a second contact surface 1121 is provided at the top of the second magnetic bar 112. Outside the U-shaped magnet formed by the permanent magnet 116, the first magnetic bar 111 and the second magnetic bar 112, magnetic lines of force propagate from the first contact surface 1111 to the second contact surface 1121 in the air.

[0071] When the first magnetic bar 111 and the second magnetic bar 112 adsorb the target spring pin 21, the first contact surface 1111 and the second contact surface 1121 contact the target spring pin 21 at the same time, so that the first contact surface 1111 and the second contact surface 1121 are connected through the target spring pin 21, so that the magnetic flux lines propagated from the first contact surface 1111 to the second contact surface 1121 propagate in the spring pin 21, thereby reducing the dispersion of the magnetic flux lines and the mutual interference with the surrounding magnetic field, and reducing the energy loss of the magnetic flux lines, thereby enhancing the adsorption force of the first magnetic bar 111 and the second magnetic bar 112 on the spring pin 21.

[0072] In the needle selection method, when the bottom of the first magnetic bar 111 is inserted into the first fixed cavity 1151 of the magnetic bar base 115, and the bottom of the second magnetic bar 112 is inserted into the second fixed cavity 1152 of the magnetic bar base 115, the first contact surface 1111 at the top of the first magnetic bar 111 and the second contact surface 1121 at the top of the second magnetic bar 112 are located on the same horizontal plane. As mentioned above, when the first magnetic bar 111 and the second magnetic bar 112 adsorb the target spring needle 21, the first contact surface 1111 and the second contact surface 1121 are in contact with the target spring needle 21 at the same time.

[0073] Therefore, in the present application, the first contact surface 1111 and the second contact surface 1121 are located on the same horizontal plane so that when the first magnetic bar 111 and the second magnetic bar 112 adsorb the target spring needle 21, the first contact surface 1111 and the second contact surface 1121 can better contact the target spring needle 21, so that the target spring needle 21 can better connect the first contact surface 1111 and the second contact surface 1121, further reduce the dispersion of magnetic flux lines, enhance the adsorption force of the first magnetic bar 111 and the second magnetic bar 112 on the target spring needle 21, thereby ensuring the accuracy of needle selection and improving production efficiency.

[0074] Furthermore, in the present application, a first limiting plate 1112 is provided on the first magnetic bar 111, and the first limiting plate 1112 is provided at one end of the first magnetic bar 111 close to the second magnetic bar 112; a second limiting plate 1122 is provided on the second magnetic bar 112, and the second limiting plate 1122 is provided at one end of the second magnetic bar 112 close to the first magnetic bar 111.

[0075] In this needle selection method, when the bottom of the first magnetic bar 111 is inserted into the first fixed cavity 1151 of the magnetic bar base 115, and the bottom of the second magnetic bar 112 is inserted into the second fixed cavity 1152 of the magnetic bar base 115, the first limiting plate 1112 and the second limiting plate 1122 are both abutted against the top of the permanent magnet 116, so that the permanent magnet 116 is limited by the first limiting plate 1112 and the second limiting plate 1122, and the permanent magnet 116 is fixed in the third fixed cavity 1153.

[0076] In addition, when the first magnetic bar 111, the second magnetic bar 112 and the permanent magnet 116 are installed on the magnetic bar base 115, at the N end of the permanent magnet 116, the first limiting plate 1112 abuts against the top of the permanent magnet 116, so that the contact area between the first magnetic bar 111 and the permanent magnet 116 can be increased; at the S end of the permanent magnet 116, the second limiting plate 1122 abuts against the top of the permanent magnet 116, so that the contact area between the second magnetic bar 112 and the permanent magnet 116 can be increased, thereby enhancing the magnetization effect of the first magnetic bar 111 and the second magnetic bar 112, and further enhancing the adsorption force of the first magnetic bar 111 and the second magnetic bar 112 on the spring needle 21, thereby ensuring the accuracy of needle selection.

[0077] Furthermore, in the needle selection method, a spacer 117 is provided between the first magnetic bar 111 and the second magnetic bar 112. Specifically, the spacer 117 is provided at one end of the first magnetic bar 111 and the second magnetic bar 112 away from the permanent magnet 116, that is, the spacer 117 is provided at a position close to the top of the first magnetic bar 111 and the second magnetic bar 112, so that the spacer 117 isolates the first magnetic bar 111 and the second magnetic bar 112 from the end of the permanent magnet 116.

[0078] It is foreseeable that, in actual implementation, the isolation sheet 117 may be made of non-magnetic materials, such as copper, aluminum, stainless steel, etc., so that the isolation sheet 117 can isolate the first magnetic bar 111 from the second magnetic bar 112 .

[0079] In the present application, the reason why the first magnetic bar 111 and the second magnetic bar 112 are isolated at one end away from the permanent magnet 116 by the isolation sheet 117 is to prevent the first magnetic bar 111 and the second magnetic bar 112 from directly contacting each other at one end away from the permanent magnet 116, thereby preventing the magnetic flux lines from propagating from the position where the first magnetic bar 111 and the second magnetic bar 112 are in direct contact outside the overall magnet formed by the permanent magnet 116, the first magnetic bar 111 and the second magnetic bar 112 to the second magnetic bar 112, thereby reducing the magnetic flux lines propagating from the spring needle 21, and thereby enhancing the adsorption force of the first magnetic bar 111 and the second magnetic bar 112 on the spring needle 21.

[0080] In this embodiment, the energized coil includes a first coil 113 provided on the first magnetic rod 111, and a second coil 114 provided on the second magnetic rod 112. The flow directions of the first coil 113 and the second coil 114 are opposite. The energized coil is energized to demagnetize the magnetic member, so that the magnetic member releases the adsorbed target spring pin 21, and the target spring pin 21 is reset under the action of its own elastic force, including: The first coil 113 is energized to demagnetize the first magnetic bar 111, and the second coil 114 is energized to demagnetize the second magnetic bar 112, so that the first magnetic bar 111 and the second magnetic bar 112 release the target spring pin 21 that is attracted, and the target spring pin 21 is reset under the action of its own elastic force.

[0081] In the present application, the energized coil includes a first coil 113 and a second coil 114, wherein the first coil 113 is disposed on the first magnetic bar 111, and the second coil 114 is disposed on the second magnetic bar 112. Since the first magnetic bar 111 and the second magnetic bar 112 exhibit opposite polarities after being magnetized, in the present application, the current flow directions of the first coil 113 and the second coil 114 are opposite, so that when the first coil 113 is energized, the magnetic field formed in the first coil 113 has a magnetic flux line direction opposite to the internal magnetic flux line direction of the first magnetic bar 111 after magnetization, so that the magnetic field formed in the first coil 113 and the magnetic field of the first magnetic bar 111 after magnetization cancel each other, thereby reducing the magnetic field strength of the first magnetic bar 111 and achieving demagnetization of the first magnetic bar 111.

[0082] When the second coil 114 is energized, the magnetic field formed in the second coil 114 has a magnetic flux line direction opposite to the internal magnetic flux line direction of the second magnetic bar 112 after magnetization. Therefore, the magnetic field formed in the second coil 114 and the magnetic field of the second magnetic bar 112 after magnetization cancel each other out, thereby reducing the magnetic field strength of the second magnetic bar 112 and achieving demagnetization of the second magnetic bar 112.

[0083] Therefore, in the present needle selection method, the energized coil is energized to demagnetize the magnetic component, so that the magnetic component releases the adsorbed target spring needle 21, and the target spring needle 21 is reset under the action of its own elastic force. The first coil 113 is energized to demagnetize the first magnetic bar 111, and the second coil 114 is energized to demagnetize the second magnetic bar 112.

[0084] When the magnetic attraction of the first magnetic bar 111 and the second magnetic bar 112 to the target spring pin 21 is less than the elastic force of the target spring pin 21 to restore its own deformation, the first magnetic bar 111 and the second magnetic bar 112 will release the adsorbed target spring pin 21 to reset the target spring pin 21, so that the needle selection method can realize the adsorption or release of the target spring pin 21 by the first magnetic bar 111 and the second magnetic bar 112, so that the target spring pin 21 can be switched between the working position and the non-working position, thereby realizing needle selection.

[0085] In actual implementation, the first coil 113 and the second coil 114 can use the same set of power supply equipment for current flow, or they can use two sets of power supply equipment for current flow. In order to make the structure of the needle selector 1 more compact and reduce production costs, in this application, it is preferred that the first coil 113 and the second coil 114 use the same set of power supply equipment for current flow.

[0086] Specifically, in this embodiment, the first magnetic bar 111 is demagnetized by energizing the first coil 113, and the second magnetic bar 112 is demagnetized by energizing the second coil 114, including: The head end of the first coil 113 is connected to the positive pole of the power supply circuit, the tail end of the first coil 113 is connected to the head end of the second coil 114, and the tail end of the second coil 114 is connected to the negative pole of the power supply circuit, so that the power supply circuit passes current to the first coil 113 and the second coil 114 at the same time.

[0087] In this needle selection method, the first coil 113 and the second coil 114 are connected in series by connecting the tail end of the first coil 113 to the head end of the second coil 114; and then a closed loop is formed by connecting the head end of the first coil 113 to the positive pole of the power supply circuit and the tail end of the second coil 114 to the negative pole of the power supply circuit, so that the power supply circuit can pass current to the first coil 113 and the second coil 114 at the same time, thereby making the structure of the needle selector 1 more compact and reducing the production cost.

[0088] Furthermore, in the needle selection method, the first coil 113 and the second coil 114 can be made of the same enameled wire. Specifically, the enameled wire is firstly wound in a spiral shape from bottom to top on the outer periphery of the first magnetic bar 111 to form the first coil 113; then, at the top of the first coil 113, the enameled wire is horizontally pulled to the second magnetic bar 112, and is wound in a spiral shape from top to bottom on the outer periphery of the second magnetic bar 112 to form the second coil 114, thereby realizing the series connection of the first coil 113 and the second coil 114; finally, the head end of the enameled wire is connected to the positive pole of the power supply circuit, and the tail end is connected to the negative pole of the power supply circuit, thereby forming a closed loop, so that the power supply circuit can simultaneously pass current to the first coil 113 and the second coil 114, thereby reducing production costs.

[0089] In the needle selection method, the first coil 113 is made by winding the enameled wire from bottom to top in a spiral shape around the outer periphery of the first magnetic bar 111; the second coil 114 is made by winding the enameled wire from bottom to top in a spiral shape around the outer periphery of the second magnetic bar 112. The first coil 113 and the second coil 114 are connected in series by pulling the enameled wire horizontally from the top of the first coil 113 to the second magnetic bar 112.

[0090] That is, the tail end of the first coil 113 is located at the top of the first coil 113, and the head end of the first coil 114 is located at the top of the second coil 114. Therefore, the enameled wire is at the top of the first coil 113 and the top of the second coil 114, and the first coil 113 and the second coil 114 are connected in series. This can not only reduce the use of enameled wire, thereby reducing production costs, but also make the series connection of the first coil 113 and the second coil 114 simpler, making the implementation of the needle selection method simple and convenient, and further improving production efficiency.

[0091] Furthermore, in the present needle selection method, the enameled wire is spirally wound around the outer circumference of the second magnetic bar 112 from top to bottom to form the second coil 114, and then the enameled wire is horizontally pulled to the first magnetic bar 111 at the bottom of the formed second coil 114, so that the tail end of the second coil 114 and the head end of the first coil 113 are located on the same side, and then the head end of the enameled wire is connected to the positive pole of the power supply circuit on the same side, and the tail end is connected to the negative pole of the power supply circuit, which can make the connection between the enameled wire and the power supply circuit simpler and more convenient, easy to implement, and the routing of the power supply circuit is more regular, thereby making the implementation of the present needle selection method simpler and more convenient, and further improving production efficiency.

[0092] Since the direction of the magnetic field lines of force formed in the energized coil is related to the winding direction of the current in the energized coil, it is worth noting that in actual implementation: when the first coil 113 is wound from bottom to top around the outer periphery of the first magnetic bar 111 and the second coil 114 is wound from top to bottom around the outer periphery of the second magnetic bar 112, it is necessary to design the connection direction of the current in the first coil 113 and the second coil 114 according to the right-hand screw rule, so that the direction of the magnetic field lines of force formed in the first coil 113 and the second coil 114 is the above-mentioned direction.

[0093] Furthermore, in the present needle selection method, a wiring groove 1154 is provided on one side of the magnetic rod base 115, so that the head end of the first coil 113 and the tail end of the second coil 114 are both routed through the wiring groove 1154, thereby limiting the head end of the first coil 113 and the tail end of the second coil 114 through the wiring groove 1154, so that the routing of the first coil 113 and the second coil 114 is more regular, further making the implementation of the present needle selection method simpler and more convenient, and improving production efficiency.

[0094] Furthermore, in the present application, a wiring hole 1213 is provided at the bottom of each magnetic bar limiting groove 1211, and the needle selector 1 further comprises a control board 13, which is provided at the bottom of the needle selector seat 12.

[0095] In the present application, the needle selector 1 further includes a housing 14, a cavity is provided in the housing 14, the needle selector seat 12 is provided at the top of the housing 14, and is fixedly connected to the housing 14, so that the needle selector seat 12 is fixed by the housing 14. Since the control board 13 is provided at the bottom of the needle selector seat 12, when the needle selector seat 12 is fixedly installed on the top of the housing 14, the control board 13 is located in the cavity of the housing 14, so that the control board 13 is protected by the housing 14 to prevent the control board 13 from being exposed, thereby enhancing the safety of the needle selector 1, and thus making the needle selection method more practical.
