Description

Technical Field

[0001] The invention relates to the technical field of winding machines, in particular to a casing wire threading and feeding mechanism. Background Art

[0002] A coil usually refers to a ring-shaped wire winding. The most common coils are motors, inductors, transformers, and ring antennas. For some special coils, in order to achieve certain special functions, such as shielding, wear resistance and other properties, a small section of casing will be passed through the coil. The casing is a very long piece wound on the wire storage wheel before cutting. Then the casing needs to be cut into sections by a cutting device, and then the wire is passed through the casing. In the existing technology, it is generally necessary to cut the casing into sections by a cutting device first, and then load it into the casing threading and feeding mechanism through a loading device, resulting in the need for multiple devices and difficulty in integration. At the same time, after the winding is completed, the wire will be cut to set the next casing. The existing casing threading and feeding mechanism is difficult to withdraw the wire and cannot return the wire to the position where the casing is inserted, which is not convenient for automated production. Summary of the Invention

[0003] In view of this, the present invention provides a casing threading and feeding mechanism to solve the above technical problems.

The sleeve threading and feeding mechanism includes a base plate, a threading mechanism disposed on the base plate, a sleeve cutting mechanism disposed on the base plate, and a sleeve conveying mechanism disposed on the base plate. The threading mechanism includes a screw moving device disposed on the base plate, a servo motor for driving the screw moving device, a sliding plate slidably disposed on the screw moving device, and a wire clamping cylinder disposed on the sliding plate. The wire clamping cylinder is used to clamp the wire and drive the wire to retract when the sliding plate moves. The sleeve cutting mechanism includes a mounting plate disposed on the base plate, a first cylinder disposed on the mounting plate, and a blade disposed on the first cylinder. One end of the mounting plate is connected to the base plate, and the other end is provided with a second sleeve porcelain eyelet. The first cylinder is located on the bottom surface of the mounting plate, and the cutting edge of the blade is in close contact with the opening at one end of the second sleeve porcelain eyelet. The sleeve conveying mechanism includes a first guide rail disposed on the base plate, a first slide slidably disposed on the first guide rail, a first driving cylinder for driving the first slide, an L-shaped plate disposed on the first slide, an opening and closing cylinder disposed on the L-shaped plate, and two clamping bars disposed at the output ends of the opening and closing cylinders. The opposing end surfaces of the clamping bars are provided with a semicircular groove extending through both ends of the clamping bars. The first driving cylinder drives the clamping bars to move below the threading mechanism or the sleeve cutting mechanism.

[0005] Furthermore, the threading mechanism further includes a wire stripper disposed on the sliding plate, a wire clamping cylinder disposed on the sliding plate, and a threading plate disposed on the base plate, wherein the direction of movement of the sliding plate driven by the screw moving device is parallel to the direction of gravity, and the threading plate is located at one end of the screw moving device. The threading plate is provided with a threading hole for threading the wire.

[0006] Furthermore, the cutting sleeve mechanism also includes a sleeve insertion plate arranged on the base plate, a first sleeve tube cylinder arranged on the sliding plate, a second sleeve tube cylinder arranged on the mounting plate, a U-shaped piece arranged on the mounting plate, and two adjusting bolts arranged on the U-shaped piece. The sleeve insertion plate is located at the top end of the base plate and is provided with a first sleeve insertion porcelain eye.

[0007] Furthermore, the first jacketed tube cylinder is located between the sleeve plate and the mounting plate, and a semicircular groove is provided on the opposite sides of two output ends of the first jacketed tube cylinder.

[0008] Furthermore, the second jacket tube cylinder is arranged on the top surface of the mounting plate and is located between the mounting plate and the first jacket tube cylinder.

[0010] Furthermore, the sleeve threading and feeding mechanism also includes a sleeve tube clamping mechanism arranged on the base plate, and the sleeve tube clamping mechanism includes a second guide rail arranged on the base plate, a second slide slidingly arranged on the second guide rail, a second driving cylinder driving the second slide to move, and a clamping cylinder arranged on the second slide.

[0011] Furthermore, the extension direction of the second guide rail is parallel to the moving direction of the screw moving device, and is located below the threading plate from the clamping position of the clamping cylinder.

[0012] Compared to the prior art, the present invention provides a sleeve threading and feeding mechanism with a semicircular groove extending through both ends of the clamping strips on the facing end surfaces thereof. The adjusting bolts are adjustably inserted on both sides of the U-shaped member, and the adjusting bolts abut against the side walls of the clamping strips, allowing the two clamping strips to open only slightly within the U-shaped member, allowing the sleeve to enter the two semicircular grooves without falling out.

[0018] The following is a further detailed description of specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.

[0019] like Figures 1 to 5, which is a schematic structural diagram of the casing threading and feeding mechanism provided by the present invention. The casing threading and feeding mechanism includes a base plate 10, a threading mechanism 20 disposed on the base plate 10, a casing cutting mechanism 30 disposed on the base plate 10, a casing conveying mechanism 40 disposed on the base plate 10, and a casing clamping mechanism 50 disposed on the base plate 10. It is conceivable that the casing threading and feeding mechanism also includes other functional modules, such as connection components, sensors, and installation components, etc., which are well known to those skilled in the art and will not be described in detail here.

[0020] The base plate 10 is vertically arranged and used to carry the above-mentioned functional modules. Therefore, the bed is provided with a variety of functional structures, such as screws, bolts, clamps, etc., to complete the installation and assembly of the above-mentioned functional modules. These structures can be set according to actual needs and will not be described in detail here. The casing threading and feeding mechanism can be set in multiple groups on the base plate 10 according to the number of axes of the winding machine to accommodate the simultaneous winding of multiple axes of the winding machine.

[0021] The threading mechanism 20 includes a screw moving device 21 arranged on the base plate 10, a servo motor 22 driving the screw moving device 21 to move, a sliding plate 23 slidingly arranged on the screw moving device 21, a wire stripping machine 24 arranged on the sliding plate 23, a wire clamping cylinder 25 arranged on the sliding plate 23, and a threading plate 26 arranged on the base plate 10.

[0022] The servo motor 22 can drive the screw moving device 21 to drive the sliding plate 23 to move back and forth in a straight line, thereby driving the wire stripping machine 24 and the wire clamping cylinder 25 set on the sliding plate 23 to move together to retract the wire after the winding is completed. The specific description will be explained below in conjunction with the threading. The moving direction of the sliding plate 23 driven by the screw moving device 21 is parallel to the direction of gravity. The wire stripping machine 24 is used to strip the paint on the outer surface of the passing wire to facilitate subsequent processing. The wire stripping machine 24 should be existing technology and will not be described here. The wire clamping cylinder 25 is located between the wire stripping machine 24 and the threading plate 26. The wire passing through the wire stripping machine 24 will pass through the wire clamping cylinder 25 and pass into the threading plate 26. The wire clamping cylinder 25 is used to clamp the wire to drive the wire to retract when the sliding plate 23 moves. The threading plate 26 is located at one end of the screw moving device 21. The threading plate 26 is provided with a threading hole 261 for threading a wire.

[0023] The sleeve cutting mechanism 30 includes a sleeve insertion plate 31 arranged on the base plate 10, a first sleeve clamping cylinder 32 arranged on the sliding plate 23, a mounting plate 33 arranged on the base plate 10, a second sleeve clamping cylinder 34 arranged on the mounting plate 33, a first cylinder 35 arranged on the mounting plate 33, a blade 36 arranged on the first cylinder 35, a U-shaped piece 37 arranged on the mounting plate 33, and two adjusting bolts 38 arranged on the U-shaped piece 37.

[0024] The sleeve insertion plate 31 is located at the top of the base plate 10 and is provided with a first sleeve insertion porcelain eye 311 . The uncut sleeve is output from the wire storage drum and passes through the first sleeve insertion porcelain eye 311 .

[0025] The first jacket tube cylinder 32 is located between the sleeve plate 31 and the mounting plate 33 . Two output ends of the first jacket tube cylinder 32 are provided with a semicircular groove on opposite sides, thereby forming a through hole for passing the sleeve when closed.

[0026] The mounting plate 33 is located between the first jacket tube cylinder 32 and the jacket tube conveying assembly 39 . One end of the mounting plate 33 is connected to the base plate 10 , and the other end is provided with a second jacket porcelain eye 331 .

[0027] The second jacket tube cylinder 34 is disposed on the top surface of the mounting plate 33 and is located between the mounting plate 33 and the first jacket tube cylinder 32. The structure of the output end of the second jacket tube cylinder 34 is the same as that of the output end of the first jacket tube cylinder 32. When closed, a through hole for the sleeve is formed. The sleeve extending from the first sleeve porcelain eye 311 passes through the first jacket tube cylinder 32, the second jacket tube cylinder 34, and the second sleeve porcelain eye 331 in sequence. The first jacket tube cylinder 32 and the second jacket tube cylinder 34 function to limit the sleeve. Since the sleeve has a certain degree of flexibility, the first jacket tube cylinder 32 and the second jacket tube cylinder 34 prevent it from bending during transportation.

[0028] The first cylinder 35 is located on the bottom surface of the mounting plate 33 and is used to drive the blade 36 to move back and forth. The cutting edge of the blade 36 is in close contact with the opening at one end of the second sleeve insertion eyelet 331. When the sleeve extends a certain distance from the second sleeve insertion eyelet 331, the first cylinder 35 drives the blade 36 to cut the sleeve, thereby achieving automatic sleeve cutting.

[0029] The central axis of the second sleeve porcelain eye 331 is located in the opening of the U-shaped part 37, and the adjusting bolt 38 is adjustably inserted on both sides of the U-shaped part 37, which is used to limit the sleeve conveying assembly 39. The specific description will be explained below in conjunction with the sleeve conveying mechanism 40.

[0030] The sleeve conveying mechanism 40 includes a first guide rail 41 arranged on the base plate 10, a first slide 42 slidably arranged on the first guide rail 41, a first driving cylinder 43 driving the first slide 42, an L-shaped plate 44 arranged on the first slide 42, an opening and closing cylinder 45 arranged on the L-shaped plate 44, and two clamping strips 46 respectively arranged on the output ends of the opening and closing cylinder 45.

[0031] The extension direction of the first guide rail 41 and the movement direction of the first drive cylinder 43 are perpendicular to the movement direction of the screw moving device 21, thereby driving the clamping bar 46 to move below the threading mechanism 20 or the sleeve cutting mechanism 30. The opening and closing cylinder 45 is used to drive the two clamping bars 46 toward or away from each other. The facing end surfaces of the clamping bars 46 are provided with a semicircular groove 461 extending through both ends of the clamping bar 46. The two semicircular grooves 461 are used to accommodate the sleeves to prevent the wire from being flattened after clamping.

[0032] The adjusting bolt 38 abuts against the side wall of the clamping strip 46. Since the cylinder has only two positions, the adjusting bolt 38 allows the two clamping strips 46 to be slightly opened to facilitate the sleeve to enter the two semicircular grooves 461 without falling.

[0033] After the complete cannula exits the second insertion hole 331, the two clamping strips 46 are slightly opened to allow the cannula to pass into the two semicircular grooves 461. Once the cannula has extended to the desired length, the two clamping strips 46 tighten, while the first cylinder 35 drives the blade 36 to cut the cannula, achieving automatic cannula cutting. The first slide 42 then moves, driving the clamping strips 46 to move below the threading mechanism 20, aligning the clamped cannula with the threading hole 261, thereby completing cannula delivery. The wire then passes through the threading mechanism 20 and into the clamped cannula. An external guide pin delivers the cannulated wire to the cannula, achieving automatic cannula threading. Since the wire cutting position is relatively low on the coil frame and the casing needs to be threaded again for the next winding, after the winding of the coil frame is completed, the wire clamping cylinder 25 will clamp the wire, and then the screw moving device 21 drives the sliding plate 23 to move upward, thereby clamping the wire and moving it upward, so that the wire returns to the threading plate 26, and the actions of cutting the casing and conveying the casing are repeated to realize automatic threading and threading of the casing.

[0034] The sleeve tube mechanism 50 includes a second guide rail 51 arranged on the base plate 10, a second slide 52 slidably arranged on the second guide rail 51, a second driving cylinder 53 driving the second slide 52 to move, and a clamping cylinder 54 arranged on the second slide 52.

[0035] The second guide rail 51 extends in a direction parallel to the direction of movement of the screw moving device 21, thereby driving the clamping cylinder 54 to move vertically. The clamping point of the clamping cylinder 54 is located below the threading plate 26. After threading is completed, the clamping bar 46 opens to release the sleeve. At this time, the sleeve will automatically fall down if it is not stuck. However, if the wire is bent, the sleeve will become stuck. In this case, the clamping cylinder 54 can clamp the sleeve and move it vertically to prevent it from getting stuck, thereby ensuring threading efficiency.

[0036] Compared with the prior art, the sleeve threading and feeding mechanism provided by the present invention has a semicircular groove 461 running through both ends of the clamping strip 46 on the facing end faces thereof, and the adjusting bolt 38 is adjustably inserted on both sides of the U-shaped member 37. The adjusting bolt 38 abuts against the side wall of the clamping strip 46, so that the two clamping strips 46 can only be slightly opened in the U-shaped member 37 to facilitate the sleeve to enter the two semicircular grooves 461 without falling. The first driving cylinder 43 can drive the clamping strip 46 to move to the bottom of the threading mechanism 20 or the sleeve cutting mechanism 30, thereby transporting the sleeve that has been cut. The wire clamping cylinder 25 is located between the wire stripping machine 24 and the threading plate 26. The wire passing through the wire stripping machine 24 will pass through the wire clamping cylinder 25 and pass into the threading plate 26. After the winding of the coil frame is completed, the wire clamping cylinder 25 clamps the wire, and then the screw moving device 21 drives the sliding plate 23 to move upward, thereby clamping the wire and moving it upward, so that the wire is retracted to facilitate the next sleeve insertion.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements or improvements within the spirit of the present invention are included in the scope of the claims of the present invention.
