Description

Technical Field

[0001] This invention relates to the field of winding machine technology, and more specifically to an automatic lead tip changing winding machine. Background Technology

[0002] A wire winding machine is a device that winds a wire-like object onto a specific workpiece, typically used for winding copper wire. Most electrical products require inductor coils made by winding enameled copper wire (or simply enameled wire), and a wire winding machine can complete this one or more processing steps. Examples include: various electric motors, coreless motors, rotors, stators, leaded inductors, surface mount inductors, transformers, solenoid valves, focusing coils, etc.

[0003] To improve the winding and laying effect, a guide nozzle is usually installed on the winding arm for guiding the winding. For example, invention patent publication number "CN217214460U", entitled "A Winding Machine", discloses a winding machine including: a moving mechanism and a processing mechanism; the processing mechanism is installed between the X-axis moving module and the tooling platform, the processing mechanism includes a winding assembly and a pressing core assembly, the pressing core assembly is on top of the winding assembly, a cap assembly is provided on one side of the pressing core assembly, a winding assembly is provided on one side of the winding assembly, the winding assembly includes at least a motor, a guide nozzle is installed on the side of the winding assembly near the winding assembly, a wire cutting assembly is installed on the top of the winding assembly, a lifting module is installed at the bottom of the winding assembly, a wire clamping assembly is provided on the same side of the cap assembly, the winding assembly includes a hooking mold, a fork is installed on the side of the hooking mold away from the guide nozzle, a scissor is installed at the bottom of the hooking mold, and a servo motor is connected to the bottom of the winding assembly via gears and a belt. Although it can achieve the purpose of winding, during the coil winding process, the diameter of the wire in the coil products varies. Therefore, it is necessary to manually change the wire nozzle with the corresponding aperture to adapt to the wire of different diameters, which is time-consuming, labor-intensive, and inefficient, thus affecting production efficiency. Summary of the Invention

[0004] To address the aforementioned shortcomings, the present invention aims to provide an automatic wire tip changing winding machine with a reasonable structural design that allows for convenient replacement of wire tips.

[0005] To achieve the above objectives, the technical solution provided by this invention is as follows:

[0006] An automatic lead tip changing winding machine includes a frame and a winding spindle, a winding arm, a moving mechanism, and at least two lead tip placement devices mounted on the frame. Each lead tip placement device is mounted on the frame and the number of lead tips to be replaced can be determined according to the number of lead tips to be replaced.

[0007] Each wire tip placement device is provided with a placement slot for placing the wire tip. The moving mechanism is mounted on the frame. The winding arm is provided with a wire tip clamp. The winding arm is mounted on the moving mechanism and is driven by the moving mechanism to move to the corresponding placement slot. The wire tip located in the placement slot is taken out through the wire tip clamp or the wire tip already located in the wire tip clamp is put back into the corresponding placement slot.

[0008] As a preferred embodiment of the present invention, the number of the moving mechanism and the winding arm is two sets, which can be distributed on both sides or the same side of the frame. The two winding arms work together to better meet the needs of complex working actions.

[0009] In a preferred embodiment of the present invention, the winding arm includes a bracket, a support arm, a rotary drive device, an eccentric block, and a clamping assembly. The rotary drive device is mounted on the bracket, the eccentric block is mounted on the rotation shaft of the rotary drive device, one end of the support arm is eccentrically mounted on the eccentric block, and the other end extends horizontally with the lead tip clamping opening at its end. The clamping assembly is located on the lead tip clamping opening. The clamping assembly can position the lead tip on the lead tip clamping opening, resulting in good stability.

[0010] As a preferred embodiment of the present invention, the clamping assembly includes a clamp, a linkage rod, and a linear drive device. The clamping end of the clamp is located on both sides of the wire nozzle clamping opening, and the linear drive device drives the clamp to perform clamping or releasing actions through the linkage rod.

[0011] In a preferred embodiment of the present invention, the support arm is provided with a sleeve clamping device, which includes a telescopic cylinder, a slider, a slide rail, and a gripping cylinder. The slide rail is disposed on the support arm, the slider is movably disposed on the slide rail, and the gripping cylinder is disposed on the slider at a position corresponding to the lower part of the wire nozzle clamp. The telescopic cylinder is disposed on the support arm and can drive the slider to reciprocate on the slide rail. The sleeve clamping device can clamp the sleeve to meet the production requirements of wire fitting with sleeve.

[0012] In a preferred embodiment of the present invention, the support arm is provided with a wire clamping device, which includes a wire clamping cylinder, a fixing block, and a clamping block. The clamping block is located on one side of the bottom surface of the wire nozzle clamp, and the wire clamping cylinder is located on the other side of the bottom surface of the wire nozzle clamp. The clamping block is located on the piston rod of the wire clamping cylinder and is driven by the wire clamping cylinder to move closer to or further away from the fixing block. The wire clamping device can clamp the wire end, meeting the needs of wire pulling.

[0013] As a preferred embodiment of the present invention, the support arm is provided with a wire-cutting device to achieve the purpose of wire cutting.

[0014] In a preferred embodiment of the present invention, the wire nozzle placement device includes a mounting base and a spring-loaded gripper or magnetic component disposed on the mounting base. The wire nozzle can be positioned using the clamping force of the spring-loaded gripper, or the wire nozzle can be attracted using the magnetic component, thus achieving the same positioning purpose.

[0015] The beneficial effects of this invention are as follows: The invention has a reasonable structural design. Based on the wire diameter to be wound on the coil frame, the moving mechanism drives the winding arm to move to the corresponding wire nozzle placement device, which then grips the wire nozzle and moves it to the threading position. This ensures that the aperture of the gripped wire nozzle matches the wire diameter to be wound, avoiding oversized or undersized wires. During winding, the moving mechanism drives the wire nozzle to move back and forth regularly on the winding part of the coil frame via the winding arm, ensuring the wire is neatly wound and arranged on the coil frame, resulting in good wire arrangement. When a different wire nozzle needs to be changed, the moving mechanism drives the winding arm to move to the initial position of the wire nozzle placement device, placing the wire nozzle on the wire nozzle clamp of the winding arm onto the initial placement device. Then, the moving mechanism drives the winding arm to move to another placement device position to grip the wire nozzle there, achieving automatic wire nozzle replacement. Furthermore, due to the presence of multiple wire nozzle placement devices, it can accommodate multiple wire nozzles of different diameters, meeting the diverse wire diameter requirements of coil products. The operation is simple and convenient, saving time and effort, effectively improving work efficiency, and facilitating widespread application.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0025] See Figures 1 to 7 This embodiment provides an automatic wire tip changing winding machine, which includes a frame 1, a winding arm 2, a moving mechanism 3, and a wire tip placement device 4.

[0026] For ease of installation, the main body of the frame 1 is a square frame, and the winding spindle 5 is installed at the bottom center of the square frame. Preferably, there are two sets of moving mechanisms 3 and winding arms, distributed on both sides of the square frame. Specifically, a winding arm 2 is provided on each of the left and right sides of the winding spindle 5 via a moving mechanism 3 to meet complex winding requirements. In other embodiments, there may be only one winding arm 2, or both winding arms 2 may be located on the same side. Of course, the frame 1 may also adopt other shapes.

[0027] Each wire guide nozzle placement device is located at the top of the square frame. In this embodiment, four sets of wire guide assemblies 6 are arranged side by side at the top of the square frame. In other embodiments, the number of wire guide nozzle placement devices can be determined according to the number of wire guide nozzles that need to be replaced. The wire guide assembly 6 includes a mounting plate 61 and a wire feeding assembly 62 disposed on the mounting plate 61. Preferably, a tension adjustment assembly or other components can be added to the mounting plate 61 or the frame 1 to improve the stability of wire feeding. Of course, depending on specific production needs, the wire feeding assembly 62 and the tension adjustment assembly can be omitted, and the wire can be pulled directly by the traction force when the winding spindle 5 winds the wire.

[0028] In this embodiment, a wire nozzle placement device 4 is provided on each side of each mounting plate 61, with one side higher than the other. That is, the total number of wire nozzle placement devices 4 is eight. In other embodiments, each mounting plate 61 may have only one or more wire nozzle placement devices 4. Of course, the wire nozzle placement devices 4 may also be placed on the frame 1 or other locations, but it must be ensured that the wire nozzle placement devices 4 are installed within the working range of the moving mechanism 3.

[0029] In this embodiment, the wire nozzle placement device 4 is provided with a placement slot for placing the wire nozzle 7. Specifically, the wire nozzle placement device 4 includes a mounting base 41 and elastic grippers 42 disposed on the mounting base 41. The wire nozzle 7 is cylindrical and has a slot 71 adapted to the elastic grippers 42. The wire nozzle is positioned by the clamping force of the two elastic grippers 42 engaging with the slot 71. The opening of the two elastic grippers 42 forms the placement slot. This placement slot can position the wire nozzle 7. In other embodiments, the elastic grippers 42 can also be replaced by a magnetic component. The magnetic component attracts the wire nozzle 7 to form the placement slot. The wire nozzle is attracted by the magnetic component, which can also achieve the purpose of positioning. In this way, the wire nozzle 7 does not need to have a slot 71. Figure 8 As shown.

[0030] The moving mechanism 3 includes an X-axis moving component 31, a Y-axis moving component 32, and a Z-axis moving component 33. The Z-axis moving component 33 is mounted on the frame 1, the Y-axis moving component 32 is mounted on the Z-axis moving component 33, and the X-axis moving component 31 is mounted on the Y-axis moving component 32. The winding arm 2 is mounted on the X-axis moving component 31. Through the cooperation of the X-axis moving component 31, the Y-axis moving component 32, and the Z-axis moving component 33, the winding arm 2 can be driven to move to the set placement and locking position.

[0031] See Figure 2 and Figure 3The winding arm 2 includes a bracket 21, a support arm 22, a rotary drive device 23, an eccentric block 24, and a clamping assembly 25. The rotary drive device 23 is mounted on the bracket 21, and the eccentric block 24 is mounted on the rotation axis of the rotary drive device 23. One end of the support arm 22 is eccentrically mounted on the eccentric block 24, and the other end extends horizontally with a wire tip clamp 221 at its end. The clamping assembly 25 is located on the wire tip clamp 221. The clamping assembly 25 can position the wire tip 7 on the wire tip clamp 221, resulting in good stability. Specifically, the clamping assembly 25 includes a clamp 251, a linkage rod 252, and a linear drive device 253. The clamping end of the clamp 251 is located on both sides of the wire nozzle clamping end 221. When the linear drive device 253 drives the clamp 251 to extend into the operating end of the clamp 251 via the linkage rod 252, the open end of the clamp 251 performs a clamping action. When the linear drive device 253 retracts from the operating end of the clamp 251 via the linkage rod 252, the open end of the clamp 251 releases based on its own torsion spring. When it is necessary to grasp the wire nozzle 7, the wire nozzle clamping end 221 is moved to directly below the wire nozzle 7, and then moved upward so that the wire nozzle 7 is inserted into the wire nozzle clamping end 221. At this time, the linear drive device 253 pushes out so that the open end of the clamp 251 performs a clamping action on the wire nozzle 7. Then the winding arm 2 moves in the forward direction so that the wire nozzle 7 leaves the placement position. In other embodiments, the clamping assembly 25 and the wire tip placement device 4 can also employ other clamping and positioning structures, as long as they can achieve the positioning and clamping of the wire tip 7. See also Figure 8 The clamping assembly 25 includes a pull rod chuck 254, a pull bracket 255, and a chuck cylinder 256. The pull rod chuck 254 is mounted on the wire nozzle clamp 221. The middle part of the pull bracket 255 is assembled and connected to the pulling component of the pull rod chuck 254. One end of the pull bracket 255 is hinged to the support arm 22. The chuck cylinder 256 is mounted on the other end of the pull bracket 255. When extended, the chuck cylinder 256 presses against the support arm 22. The pull bracket 255 drives the pulling component of the pull rod chuck 254 downward, causing the chuck of the pull rod chuck 254 to clamp the wire nozzle 7. When the chuck cylinder 256 retracts, the pull rod chuck 254 uses its own spring to release the wire nozzle 7, facilitating the replacement of the wire nozzle 7.

[0032] Preferably, a sleeve clamping device 26 can be provided on the support arm 22. The sleeve clamping device 26 includes a telescopic cylinder 261, a slider 262, a slide rail 263, and a gripping cylinder 264. The slide rail 263 is disposed on the support arm 22, the slider 262 is movably disposed on the slide rail 263, and the gripping cylinder 264 is disposed on the slider 262 at a position corresponding to the lower position of the wire nozzle clamp 221. The telescopic cylinder 261 is disposed on the support arm 22 and can drive the slider 262 to reciprocate on the slide rail 263. The sleeve clamping device 26 can clamp the sleeve to meet the production requirements of wire fitting with sleeve. The sleeve clamping device 26 can be set to be provided or not according to the production requirements.

[0033] See Figure 4 and Figure 5 The support arm 22 may also be equipped with a wire clamping device 27 and a wire cutting device 28. The wire clamping device 27 is positioned on the bottom surface of the support arm 22, corresponding to the position of the wire nozzle clamp 221. The wire clamping device 27 includes a wire clamping cylinder 271, a fixing block 272, and a clamping block 273. The clamping block 273 is located on one side of the bottom surface of the wire nozzle clamp 221, and the wire clamping cylinder 271 is located on the other side of the bottom surface of the wire nozzle clamp 221. The clamping block 273 is located on the piston rod of the wire clamping cylinder 271 and is driven by the wire clamping cylinder 271 to move closer to or further away from the fixing block 272. The wire clamping device 27 can clamp the wire end, meeting the needs of wire pulling.

[0034] The wire cutting device 28 is disposed on the side wall of the support arm 22. The wire cutting device 28 includes a cylinder gripper and a blade disposed on the cylinder gripper. The cylinder gripper controls the closing and opening of the blade to achieve the purpose of cutting the wire.

[0035] During operation, the coil bobbin is mounted on the winding spindle 5. Based on the wire diameter to be wound on the coil bobbin, the moving mechanism 3 drives the winding arm 2 to the corresponding position of the wire guide nozzle device 4. The wire guide nozzle clamp 221 of the winding arm 2 grips the wire guide nozzle 7 on the wire guide nozzle device 4 and then moves it to the threading position. It is ensured that the aperture of the gripped wire guide nozzle 7 matches the wire diameter to be wound, avoiding oversized or undersized issues. Next, the wire is fed through the wire guide nozzle 7 located at the threading position by the cooperation of the wire guide wheel, tension adjustment assembly, and wire feeding assembly 62. Then, the end of the wire can be manually gripped and guided to the coil bobbin on the winding spindle 5 for positioning and fixation. Of course, if... Figure 1 and Figure 4As shown, automatic wire leading can also be achieved by cooperating with the winding arm 2 on the left. Specifically, the winding arm 2 on the left also picks up a wire nozzle 7 with a corresponding aperture from another wire nozzle placement device 4 and moves it below the winding arm 2 on the right, so that the two wire nozzles 7 in the upper and lower positions are aligned. The end of the wire can pass through the two wire nozzles 7 in sequence and extend to the position of the wire clamping device 27. The wire clamping device 27 clamps and fixes the end of the wire, and the winding arm 2 on the left leads the wire to the coil frame for positioning and fixing, thus achieving the purpose of automatic wire leading. During winding, the moving mechanism 3 drives the wire nozzle 7 to move back and forth regularly on one side of the winding part of the coil frame through the winding arm 2, so that the wire is neatly wound and arranged on the coil frame, resulting in good wire arrangement.

[0036] When it is necessary to change to a different lead tip 7, the moving mechanism 3 drives the winding arm 2 to move to the lead tip placement device 4 at the initial position, so that the lead tip 7 on the lead tip clamp 221 of the winding arm 2 is placed on the lead tip placement device 4 at the initial position. Then, the moving mechanism 3 drives the winding arm 2 to move to another lead tip placement device 4 position to grab the lead tip 7 thereon, thereby achieving the purpose of automatic lead tip replacement.
