Description

Technical Field

[0001] This utility model relates to the field of motor winding equipment, and in particular to a synchronous drive structure for the winding shaft and the workpiece shaft. Background Technology

[0002] An automatic winding machine is an industrial device that precisely winds threaded objects onto a specific workpiece. With the development of production, the demand for motors has also increased, including brushed motors and brushless motors.

[0003] The motor generally includes an iron core, which has outwardly extending coils. Enamelled wire is wound around the coils in sequence to form a predetermined electromagnetic direction.

[0004] Especially with the development of automated equipment (such as electric vehicles and home improvement equipment), the winding of motors has become a key factor in driving.

[0005] Existing winding equipment generally includes a positioning device for positioning the iron core, a guard plate assembly for guiding the enameled wire into the winding turn, and a winding device rotatably mounted on the guard plate assembly.

[0006] By shifting the winding device and the guard plate assembly forward and backward, single-layer or multi-layer winding of the wire turns can be achieved.

[0007] However, in the existing winding process of parallel enameled wires with an iron core, at least two enameled wires or flat enameled wires (where the flat enameled wire can be a single flat wire or two enameled wires combined to form a flat wire) are wound side by side. After a predetermined number of turns, the parallel wire groups will shift due to the rotation of the fork, resulting in twisting and affecting the stability of the winding. The current approach is generally to use low-density winding, that is, to increase the spacing between adjacent parallel wire groups to correct the shift, but the electromagnetic properties will also be affected accordingly.

[0008] Of course, there are other solutions, but when applied to the high-speed rotation of the motor, they still cannot solve the problem of parallel alignment. Of course, reducing the speed of the flying fork is also one of the solutions, but the efficiency will also decrease accordingly.

[0009] However, the two methods mentioned above still have significant limitations when dealing with more than two enameled wires, and the offset will be more noticeable.

[0010] Therefore, a synchronous rotating winding device was designed, but the key to the design is how to ensure that the iron core and the winding mechanism rotate synchronously and move along the turns. Utility Model Content

[0011] The main objective of this invention is to propose a synchronous drive structure for the winding shaft and the workpiece shaft, aiming to solve the aforementioned technical problems.

[0012] To achieve the above objectives, this utility model proposes a synchronous drive structure for the winding shaft and the workpiece shaft, comprising:

[0013] frame;

[0014] A positioning mechanism, comprising a first base disposed on a frame, a first rotating seat rotatably mounted on the first base, and a second base disposed at the front end of the first rotating seat;

[0015] The second base is equipped with a clamping device for mounting the iron core, and the clamping device is pivotally mounted on the second base;

[0016] A winding mechanism is located opposite to the clamping device. The winding mechanism includes a third base slidably mounted on the frame, a second rotating base pivotally mounted on the third base, and an upper protective mold and a lower protective mold slidably mounted on the front end of the second rotating base.

[0017] The third driving device is used to drive the first rotary table and the second rotary table to rotate synchronously.

[0018] Technical effects of this utility model's technical solution:

[0019] A third drive device is used to drive the first and second rotary seats. Through a reasonable positional layout, synchronous rotation is achieved, ensuring the consistency of their rotation, and also guaranteeing the precision of synchronous winding of the guard plate, upper template, and lower template.

[0020] At the same time, the second rotating seat can slide along the length direction, thereby realizing synchronous rotation between the wire coil and the winding mechanism. Attached Figure Description

[0061] like Figures 1 to 21 As shown, a synchronous drive structure for a winding shaft and a workpiece shaft includes:

[0062] Rack 1;

[0063] Positioning mechanism 2, the positioning mechanism 2 includes a first base 21 disposed on the frame 1, a first rotating seat 23 rotatably mounted on the first base 21, and a second base 22 disposed at the front end of the first rotating seat 23;

[0064] The second base 22 is equipped with a clamping device 4, which is used to install the iron core. The clamping device 4 is pivotally mounted on the second base 22.

[0065] The rotation setting adjusts the angle of the iron core and positions the wire coil in the winding position. The drive clamping device 4 can be an external or internal structure.

[0066] The external structure, such as the clamping device 4 and the second base 22, is provided with a self-locking device, and its rotation is adjusted by the external drive structure.

[0067] The winding mechanism 5 is located opposite the clamping device 4. The winding mechanism 5 includes a third base 51 slidably mounted on the frame 1, a second rotating base 52 pivotally mounted on the third base 51, and an upper protective mold 53 and a lower protective mold 54 slidably mounted on the front end of the second rotating base 52.

[0068] The frame 1 is provided with a first drive device 581 that drives the third base 51 to switch between positions that are far apart or close to the clamping device 4;

[0069] The third base 51 is provided with a second driving device 582 for driving the upper protective mold 53 and the lower protective mold 54 to move relative to each other;

[0070] The third driving device 7 is used to drive the first rotary table 23 and / or the second rotary table 52 to rotate synchronously.

[0071] The wire feeding mechanism 8 is located at the position of the positioning mechanism 2 and the winding mechanism 5 (it can be above, below, or to the side (e.g., directly to the side or obliquely to the side), with the preferred option being above). The wire feeding mechanism 8 is provided with a moving mechanism, which is used to drive the wire feeding mechanism to move along a predetermined direction. The wire feeding mechanism is used to guide the arrangement of at least two enameled wires or flat enameled wires and to convey at least two enameled wires or flat enameled wires along the predetermined direction.

[0072] In the actual winding process:

[0073] Step 1: Install the iron core onto the clamping device 4;

[0074] Step 2: Select a predetermined number of enameled wires and thread them side-by-side through the transmission device;

[0075] Step 3: Secure the ends of at least two enameled wires or flat enameled wires to the winding post or coil by hand or with a robotic arm;

[0076] Step 4: The first telescopic device 28 drives the second through shaft 25 to move backward and makes the guard plate 31 fit against the front wall of the iron core. At the same time, the rocker plate 35 drives the clamping seat 32 to move forward and makes the non-wound wire turn (preferably the wire turn to be wound is arranged opposite to the wire turn) stuck in the clamping groove 321 of the clamping seat 32, thereby achieving precise positioning.

[0077] Step 5: The first driving device 581 drives the third base 51 to move, and causes the second rotating seat 52 to move toward the winding position of the wire turn, and causes the profile seat 57 to elastically fit against the end wall of the wire turn. At the same time, the upper protective mold 53 and the lower protective mold 54 fit against the upper and lower walls of the wire turn.

[0078] Step 6: The moving mechanism drives the transmission device to adjust its position. Therefore, in addition to adjusting the position, the moving device can also play a role in avoiding misalignment.

[0079] Step 7: The third drive device 7 is used to drive the first rotary table 23 and the second rotary table 52 to rotate synchronously;

[0080] At the same time, the second rotating base 52 and the lateral moving device 811 move forward or backward, adjusting according to the position of the wound wire ends, and causing multiple enameled wires to actively wind around the coil and along the length of the coil.

[0081] Step 8: After the first layer is wound, the second rotating seat 52 and the lateral moving device 811 wind the second layer in the opposite direction, and reciprocate the winding of the predetermined number of layers.

[0082] When the winding of the wire in step 8 is completed

[0083] Step 9: The first drive device 581 drives the third base 51 to move, and causes the second rotating base 52 to move away from the winding position of the wire turn.

[0084] The first telescopic device 28 drives the second through shaft 25 to move forward and drives the guard plates 31 on both sides to move forward. At the same time, the clamping seat 32 moves backward.

[0085] Step 10: The third rotating device 29 drives the first through shaft 24 to rotate, and drives the clamping device 4 to rotate by a predetermined angle through the linkage component.

[0086] Step 11: Repeat steps 1-10 until all the wire turns of the iron core are wound.

[0087] After step 8 is completed, a winding device (which can move vertically and rotate) is also included, which is used to wind the enameled wire onto the winding rod.

[0088] Step 12: Remove the top cover of clamping device 4 and take out the wound iron core.

[0089] In step 5, the first drive device 581 drives the third base 51 to move. At the same time, the second drive wheel 73 slides with the third base 51, and the second synchronous belt moves and drives the second rotating seat 52 to rotate. That is, while rotating, it also needs to move back and forth, and make the parallel wires wound on the wire coil.

[0090] In step 2, including step 21, the enameled wire is inserted into the flat conductor groove 822 through the wire feeding device and at least two enameled wires or flat enameled wires are arranged side by side, and then wound into a wire coil. When the conductor groove rotates at a predetermined angle, the relative angle between it and the wire coil is adjusted. Of course, the arrangement does not have to be side by side, but can be arranged according to actual needs.

[0091] Of course, it has been verified that this equipment can be applied to winding single enameled wires, although its winding efficiency is lower than that of existing flying fork winding equipment.

[0092] In step 8, the longitudinal moving device 812 and the vertical moving device 813 adjust their relative spacing according to the tightness of the enameled wire.

[0093] Specifically, the second base 22 includes a vertical base 221 and a horizontal base 222 extending from the end of the vertical base 221, and the clamping device 4 is disposed on the horizontal base 222.

[0094] Specifically, the first rotary seat 23 has a first clearance channel 26 in the middle, and a first through shaft 24 is pivotally mounted in the first clearance channel 26.

[0095] The front end of the first through shaft 24 and the lower end of the clamping device 4 are connected by a linkage component.

[0096] The rear end of the first shaft 24 is provided with a third rotating device 29 for driving its rotation.

[0097] The third rotating device 29 is a rotary cylinder or a rotary motor.

[0098] The third rotating device 29 is connected to the rear end of the first rotating shaft 24 via a belt, wherein the rear end of the first rotating shaft 24 extends out of the first rotating seat 23.

[0099] Specifically, the linkage component is a ratchet assembly 291 (of course, it can also be an existing gear assembly or belt linkage structure).

[0100] For example, as shown in the figure, it includes a first ratchet portion disposed on the first through shaft 24, a second ratchet portion disposed at the bottom of the clamping shaft 41 of the clamping device 4, a first vertical shaft, and a second horizontal shaft, wherein the two ends of the first vertical shaft are respectively engaged with the first ratchet portion and the second horizontal shaft.

[0101] The other end of the second horizontal shaft engages with the second ratchet portion.

[0102] Therefore, the ratchet assembly 291 and the second base 22 rotate simultaneously.

[0103] Specifically, a one-way bearing is provided between the first through shaft 24 and the first clearance channel 26. When the first rotating seat 23 rotates, the first through shaft 24 rotates with the first rotating seat 23. The third rotating device rotates in the opposite direction to the first rotating seat 23. When the third rotating device 29 rotates, the third rotating device 29 drives the ratchet assembly 291 to rotate and drives the clamping device 4 to rotate by a predetermined angle.

[0104] The first through shaft 24 has a through-passage second clearance channel 27 in the middle, the second clearance channel 27 has a second through shaft 25 that slides along its length, and the rear end of the second through shaft 25 has a first telescopic device 28 for driving it.

[0105] The front end of the second through shaft 25 is used to drive the inner wall of the guard plate 31 to slide between a position that is in contact with or away from the front wall of the iron core, and the guard plate 31 is slidably mounted on the second base 22.

[0106] Specifically, a guard plate guide rail and a guard plate slider are provided to enable forward and backward movement;

[0107] The second shaft can rotate relative to the drive end of the first telescopic device 28.

[0108] This means that the second pivot 25 can rotate relative to the first telescopic device 28, which is unaffected. The first telescopic device 28 is mounted on the frame 1, and it drives the two guard plates 31 to move back and forth.

[0109] The guard plate 31 rotates relative to the second base 22.

[0110] The second base 22 is provided with a clamping seat 32 that mates with the first through shaft 24. The clamping seat 32 is provided with a clamping groove 321, which is adapted to the width of the wire turn.

[0111] The second through shaft 25 is used to drive the clamping seat 32 to move back and forth.

[0112] The function of the clamping seat 32 is to clamp the iron core, and at the same time, it can accurately ensure that the wire turns to be wound are precisely located in the clamping position, thereby reducing the winding deviation, ensuring the winding accuracy, and reducing the offset generated during rotation, thus improving the winding accuracy.

[0113] The second through shaft 25 includes a first linkage part 33 disposed in the middle and second linkage parts 34 disposed on both sides of the first linkage part 33.

[0114] The first linkage part 33 is used to drive the clamping seat 32, and the second linkage part 34 is used to drive the guard plate 31.

[0115] A rocker plate 35 is provided between the first linkage part 33 and the clamping seat 32. The middle part of the rocker plate 35 is pivotally mounted on the second base 22. The upper end of the rocker plate 35 is connected to the front end of the bottom wall of the clamping seat 32, and the lower end of the rocker plate 35 is pivotally connected to the first linkage part 33.

[0116] This can be understood as follows: when the second pivot 25 moves forward, the clamping seat 32 moves backward via the rocker 35; when the second pivot 25 moves backward, the clamping seat 32 moves forward.

[0117] When the second guide shaft 25 moves forward, it drives the guard plate 31 to move backward and the clamping seat 32 to move forward. Therefore, the adjustable angles of the guard plate 31, the clamping seat 32, and the clamping device 4, as well as the relative rotation of the first rotating seat 23, are integrated into one structure, which can effectively simplify production. At the same time, the structure is more stable and the linkage and adjustment are easier, especially for small-diameter precision enameled wires.

[0118] Specifically, the axis of the second base 22 is tangent to the axis of the first rotating base 23.

[0119] Specifically, the clamping device 4 includes a clamping shaft 41 and a cover plate 42 detachably mounted on the upper end of the clamping shaft 41. The cover plate 42 extends outward and abuts against the top wall of the iron core, thereby ensuring that the first rotating seat 23 can clamp the iron core stably while rotating.

[0120] Specifically, the clamping shaft 41 is provided with at least two winding rods for enameled wire or flat wire extending upwards. The detachable method is screws or buckles, which means that the upper and lower ends of the iron core are limited by the cooperation of the clamping shaft 41 and the cover plate 42.

[0121] Specifically, the maximum radius of the first base 21 is greater than the maximum rotation radius of the second base 22, thus playing a protective role. Specifically, it can be understood that the diagonal length of the second base 22 is less than the width of the two sides of the first base 21, thus protecting the staff.

[0122] Specifically, the first driving device 581 includes a first guide rail, a first slider slidably mounted on the first guide rail, and a first lead screw assembly that drives the first slider to move. The first lead screw assembly includes a first rotating device, a first ball screw connected to the first rotating device, and a first lead screw nut that cooperates with the first ball screw. The first lead screw nut is disposed on the first slider, and the third base 51 is disposed on the first slider.

[0123] When the third base 51 moves back and forth, the upper protective mold 53 and the lower protective mold 54 also move back and forth, thereby guiding the enameled wire.

[0124] Specifically, the second driving device 582 includes a second guide rail disposed on the second rotary seat 52, two sets of second sliders slidably mounted on the second guide rail, and a mold protection driving device for driving the two second sliders to move relative to each other.

[0125] The upper protective mold 53 and the lower protective mold 54 are respectively installed on the second slider, thereby realizing that the upper protective mold 53 and the lower protective mold 54 rotate with the second rotating shaft, and at the same time realize the relative movement between the two.

[0126] The mold protection drive device includes a tension spring disposed between the two second sliders, the tension spring being used to apply a spring force to the upper mold protection 53 and the lower mold protection 54 to bring them closer together.

[0127] The second rotary seat 52 is provided with a third clearance channel 55, and the third clearance channel 55 is provided with a telescopic shaft 56, which is connected to the second telescopic device 583.

[0128] The rear ends of the two second sliders are respectively provided with mutually cooperating drive seats, and there is a driving inclined surface opposite to each other between the two drive seats.

[0129] An active seat 62 is provided between the two driving inclined surfaces, and the active seat 62 is provided with an ejector inclined surface that cooperates with the driving inclined surfaces.

[0130] The active seat 62 is connected to the second telescopic device 583.

[0131] The upper mold 53 and the lower mold 54 are close together to fit against the upper and lower end walls of the coil, thereby guiding and pressing the enameled wire so that the enameled wire is arranged along the length of the coil.

[0132] The rear end of the second rotary seat 52 is provided with a follower seat (fixed setting), and the follower seat is provided with a first slot for installing the active seat 62 (that is, the active seat 62 rotates synchronously with the second rotary seat 52).

[0133] The first slot has follower slots at both the upper and lower ends, and the drive seat is slidably installed in the follower slots. Similarly, the drive seat rotates synchronously.

[0134] The drive end of the second telescopic device 583 is pivotally connected to the active seat 62.

[0135] Specifically, when the active seat 62 rotates, the drive end of the second telescopic device 583 remains stationary. The second telescopic device is only responsible for the horizontal movement of the active seat 62, which can be understood as forward and backward movement.

[0136] Specifically, the front end of the second rotary seat 52 is provided with a profile seat 57 that slides along its length.

[0137] The guide rail and slider are provided between the copying seat 57 and the second rotating seat 52, and an ejection spring is provided to make the copying seat 57 move towards the clamping device 4, thereby achieving contact with the iron core, and allowing the upper mold 53 and the lower mold 54 to move back and forth, ensuring the guidance of the enameled wire.

[0138] Specifically, the profile holder 57 has a recessed fitting groove on the wall of the clamping device 4, which is used for the end face of the wire turn to extend into, thereby playing a protective and guiding role. The two sides of the wire turn are generally provided with edges.

[0139] Specifically, the molding base 57 is provided with guide grooves in the horizontal direction at both ends of its height. The upper mold 53 and the lower mold 54 are slidably installed in the two guide grooves, wherein the guide grooves mainly serve to limit and guide them, and the upper mold 53 and the lower mold 54 can also slide along the height direction.

[0140] Specifically, the third driving device 7 includes two synchronous servo motors or synchronous servo cylinders, which are used to drive the first rotary table 23 and the second rotary table 52 to rotate synchronously, that is, a dual-drive structure is adopted, thereby ensuring the synchronous rotation of the first rotary table 23 and the second rotary table 52.

[0141] Specifically, the bottom of the third base 51 and the frame 1 are provided with clearance grooves, the rear end of the second rotating base 52 is provided with a second driven wheel 74, and the bottom wall of the frame 1 is provided with the third driving device 7.

[0142] The third base 51 is provided with a receiving seat extending into the clearance groove. The receiving seat is provided with a pivotally mounted second driving wheel 73 (equivalent to the second driving wheel 73 being mounted on the receiving seat and sliding with it). The third driving device 7 is a third rotating device 29.

[0143] The third rotating device 29 is provided with a third drive shaft 70.

[0144] The second driving pulley 73 and the second driven pulley 74 are connected by a timing belt.

[0145] When the third base 51 slides horizontally, the second drive wheel 73 can slide along the length direction of the third drive shaft 70.

[0146] The third base 51, the receiving seat, the second rotating seat 52, the second driving pulley 73, the second driven pulley 74, and the timing belt are essentially a single unit that can move as a whole.
