[0002] A winding machine is a device that winds linear objects around specific workpieces, usually used for winding copper wires. Currently, there are few winding machines using opening and closing guide needles in the market. For example, Chinese Patent CN201922074212.5 discloses a guide needle table of a sleeve winding machine, which includes a flat plate. Two guide rails are arranged in parallel on both sides above the flat plate. A horizontal driving device is arranged between the two guide rails and is fixed on the flat plate through a fixing seat. A horizontal moving table is arranged on the horizontal driving device. A rotating motor is arranged below the flat plate. The output shaft of the rotating motor faces the flat plate and is connected with a transmission gear system. One end of the transmission gear system is provided with a rotating central shaft. The top end of the rotating central shaft is connected with a rotating table. A clamping cylinder and an opening and closing guide needle cylinder are arranged on the rotating table. The output end of the clamping cylinder is provided with a clamping clip and a wire cutting knife. The output end of the opening and closing guide needle cylinder is provided with two opening and closing guide needles. This winding machine reduces the number of wire passing guide needles through the opening and closing guide needles. However, when the opening and closing guide needles are closed, the situation of clamping the wire unevenly or obliquely may occur, thus reducing the winding accuracy. Summary of the Utility Model

Arc grooves are respectively opened on one side of the two semi-guide needles facing each other. A number of grooves and convex blocks are arranged on one side of the two semi-guide needles close to the opening and closing cylinder facing each other. The convex block on one semi-guide needle protrudes towards the groove on the other corresponding semi-guide needle. The convex block is located on one side of the arc groove close to the opening and closing cylinder, and one side of the convex block abuts against the edge of the arc groove.

[0015] The following further details the specific embodiments of the present utility model. It should be understood that the description of the embodiments of the present utility model herein does not limit the protection scope of the present utility model.

[0016] As Figure 1 shown, it is a schematic structural view of a high-precision wire-pulling and wire-clamping mechanism with tension provided by the present utility model. The high-precision wire-pulling and wire-clamping mechanism with tension includes a bracket 10, a single-axis moving component 20 disposed on the bracket 10, a wire-clamping component 30 disposed at the output end of the single-axis moving component 20, and a wire-winding component 40 disposed on the bracket 10 and on one side of the single-axis moving component 20. It can be conceived that the high-precision wire-pulling and wire-clamping mechanism with tension further includes some other functional modules, such as a power supply module, a wire guiding module, etc., which are well-known technologies to those skilled in the art and will not be elaborated herein one by one.

[0017] The bracket 10 is used to carry each component, so that various cooperations can be generated between them, thereby completing the wire-winding operation on the wire.

[0018] The single-axis moving component 20 can drive the wire-clamping component 30 to move reciprocally, so as to achieve the function of pulling the wire. The single-axis moving component 20 itself is a prior art and will not be elaborated herein.

[0019] Please refer to Figures 2 to 4 together. The wire-clamping component 30 includes a support plate 31, at least one slide rail 32 disposed on the support plate 31, at least four sliders 33 slidably disposed on the slide rail 32, at least four clamping cylinders 34 respectively disposed on the sliders 33, at least four first stoppers 35 respectively disposed on one side of the sliders 33, at least four springs 36 respectively disposed on one side of the four sliders 32, a limit cylinder 37 disposed on the support plate 31, a guide rod 38 disposed at the output end of the limit cylinder 37, and at least four second stoppers 39 respectively disposed on one side of the four sliders 33.

[0020] The support plate 31 is arranged at the output end of the single-axis moving assembly 20. Thus, by driving the single-axis moving assembly 20, the clamping cylinder 34 on the support plate 31 generates a displacement, thereby completing the wire pulling operation to tighten the wire. The output direction of the single-axis moving assembly 20 is parallel to the length direction of the slide rail 32. Thus, when performing the wire pulling operation, the clamping cylinder 34 clamps the wire, and the clamping cylinder 34 is displaced on the slide rail 32 through the slider 33 to cooperate with the spring 36 to apply a certain tension to the wire. The specific cooperation situation will be described below.

[0021] A wire clamping jaw is arranged at the output end of the clamping cylinder 34. The wire clamping jaw can be closed under the drive of the clamping cylinder 34, thereby clamping the starting wire of the wire, and further fixing the starting wire of the wire to facilitate the subsequent wire winding operation.

[0022] The first stop block 35 is fixedly arranged on the support plate 31 and is located on one side of the slider 33. One end of the spring 36 is hooked on the first stop block 35, and the other end is hooked on the slider 33. Thus, under the action of the spring 36, the slider 33 and the first stop block 35 are in mutual contact. The length direction of the spring 36 is parallel to the length direction of the slide rail 32. Thus, when performing the wire winding operation, when the wire is too tight, the slider 33 moves away from the first stop block 35 to relax the wire, the spring 36 is stretched, and a certain tension is applied to the wire to make it in a state of neither relaxation nor tightness for the wire winding operation.

[0023] The output direction of the limiting cylinder 37 is parallel to the length direction of the slide rail 32, the length direction of the guide rod 38 is parallel to the length direction of the slide rail 32, at least four second stop blocks 39 are fixedly arranged on the guide rod 38, and at least four second stop blocks 39 are respectively located on one side of the corresponding four sliders 33 away from the first stop block 35. The limiting cylinder 37 can drive the guide rod 38 to perform a reciprocating motion, thereby changing and controlling the distance between the second stop block 39 and the slider 33 to control the maximum sliding distance of the slider 33 and prevent the wire from being overly loose.

[0024] The wire winding assembly 40 includes at least four lifting cylinders 41 arranged on the bracket 10, at least four opening and closing cylinders 42 respectively arranged at the output ends of the at least four lifting cylinders 41, and at least eight fingers 43 respectively arranged at the output ends of the four opening and closing cylinders 42.

[0025] The output direction of the lifting cylinder 41 is perpendicular to the output direction of the single-axis moving assembly 20. The lifting cylinder 41 can drive the opening and closing cylinder 42 to perform a lifting operation, thereby performing a wire winding operation on the wire.

[0026] The opening and closing cylinder 42 can drive the two finger clips 43 to perform opening or closing operations. A semiconductor pin 44 is respectively arranged on each of the two corresponding finger clips 43 along the length direction of the wire. An arc groove 45 is respectively formed on one side of the two semiconductor pins 44 facing each other. In this way, when the two finger clips 43 are in a closed state, the two semiconductor pins 44 are combined with each other, and the two arc grooves 45 form a channel for the wire to pass through, so as to guide the wire.

[0027] A number of grooves 46 and protrusions 47 are arranged on one side of the two semiconductor pins 44 facing each other close to the opening and closing cylinder 42, and the protrusion 47 on one semiconductor pin 44 protrudes towards the groove 46 on the other corresponding semiconductor pin 44, so that the protrusion 47 can be clamped in the groove 46. The protrusion 47 is located on one side of the arc groove 45 close to the opening and closing cylinder 42, and one side of the protrusion 47 abuts against the edge of the arc groove 45. In this way, when the two finger clips 43 are in an open state, the wire is located between the two arc grooves 45. The lifting cylinder 41 drives the opening and closing cylinder 42 to press down the wire, so that the wire is tightly attached to the protrusion 47, and then the closing operation is performed. In this way, it is ensured that the wire can be completely accommodated in the channel formed by the two arc grooves 46, and when the opening and closing cylinder 42 drives the two finger clips 43 to close, the wire is prevented from being clamped or deflected, and the wire winding accuracy is improved.

[0028] Compared with the prior art, the high-precision wire taking and clamping mechanism with tension provided by the present utility model clamps the starting wire of the wire by the clamping cylinder 34 arranged on the slider 33. When the wire is too tight, the slider is pulled to relax the wire, the spring 36 is stretched, and a certain tension is applied to the wire, so that the wire winding operation is carried out in a state of neither relaxation nor tightness. The protrusion 47 on the two semiconductor pins 44 can make the wire tightly attached to the protrusion 47 when the two finger clips 43 are in an open state, ensuring that the wire can be completely accommodated in the channel formed by the two arc grooves 46, and preventing the wire from being clamped or deflected when the opening and closing cylinder 42 drives the two finger clips 43 to close, and improving the wire winding accuracy.

[0029] The above is only the preferred embodiment of the present utility model, and is not used to limit the protection scope of the present utility model. Any modification, equivalent replacement or improvement within the spirit of the present utility model is covered by the claims of the present utility model.
