Description

Technical Field

[0001] This invention relates to the field of winding equipment technology, and more specifically to an automatic winding device. Background Technology

[0002] Plastic and nylon wires are often used as blades in lawnmowers. During production, processing and transportation, plastic wires need to be wound on a spool. Currently, the spool winding process has evolved from traditional manual operation to automation, but there are still many pain points in the existing technology that need to be addressed. In small to medium-sized production settings, lawnmower spool winding often relies on manual operation or simple semi-automatic equipment. When winding manually, operators must manually wind the mowing rope around the spool frame, which is not only labor-intensive and inefficient, but also relies entirely on experience to control the evenness of the winding, making it impossible to achieve a uniform standard. Even with semi-automatic winding equipment, manual assistance is still required for spool loading, rope end fixing, and unloading. Furthermore, the lack of precise control over the rope spacing often results in overlapping and crisscrossing of the coils, reducing the spool's rope capacity and increasing the risk of rope breakage during lawnmower operation.

[0003] The current winding process of lawnmower coils faces problems such as high dependence on manual labor, insufficient automation, and poor winding quality stability. Existing technologies are either limited to the built-in wire replenishment function of the equipment or are difficult to adapt to the special winding requirements of lawnmower coils, and cannot meet the production requirements of modern manufacturing industry for high efficiency, high precision, and full-process automation.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] like Figure 1-8 As shown, an automatic winding device includes a main support, a spool feeding mechanism, a spool orienting mechanism, a spool fixing mechanism, a winding mechanism, a wire clamping mechanism, a cutting mechanism, a wire feeding mechanism, a pushing and unloading mechanism, and a pushing mechanism. The wire reel feeding mechanism and the wire reel fixing mechanism are arranged opposite to each other; the wire reel orienting mechanism is located on one side of the wire reel fixing mechanism; the winding mechanism cooperates with the wire reel fixing mechanism and is arranged coaxially; the wire clamping mechanism and the wire feeding mechanism are arranged side by side; the cutting mechanism is located above one side of the wire feeding mechanism; the wire feeding mechanism and the winding mechanism are arranged opposite to each other; the pushing and unloading mechanism is located on one side of the wire reel fixing mechanism; the pushing mechanism is located between the winding mechanism and the wire feeding mechanism, and is used to evenly wind the plastic wire onto the wire reel.

[0020] The main support frame is used to fix the various mechanisms, including the base and the brackets for mounting the various mechanisms; The wire reel feeding mechanism includes a feeding track 30, a feeding push cylinder 1, and a wire reel pusher 2; wherein the feeding track 30 is inclined downward and automatically enters the wire reel pusher 2 by gravity. The wire reel pusher 2 is located at the end of the feeding track 30, and the feeding pusher cylinder 1 is fixedly connected to the wire reel pusher 2. Specifically, the wire reel pusher 2 includes a pusher plate 201, a clip 202 located on one side of the pusher plate 201, and a stop bar 203 located on the other side of the pusher plate 201. There are two clips 202 arranged in a V-shape, which can be used to position the cylindrical wire reel. The stop bar 203 is used to ensure that the wire reel in the feeding track 30 will not continue to slip when the wire reel pusher feeds the parts forward.

[0021] The reel orientation mechanism includes a top component assembly and a rotary orientation assembly; the top component assembly includes a top component cylinder and a top component rod 4 connected to the top component cylinder; the top component cylinder is used to drive the top component rod 4 to move horizontally, and during the rotation of the reel, it interferes with the positioning hole on the reel so that the positioning hole is positioned against the front end of the top component rod 4 to achieve reel orientation. The rotary orientation component is mounted on a bracket above the wire reel fixing mechanism. The rotary orientation component includes a rotary motor 5, a motor rotating seat (hinged to the bracket), a rotating wheel 13, and a wire-pulling motor 12. The rotary motor 5 is mounted on the motor rotating seat, the rotating wheel 13 is connected to the rotating shaft of the rotary motor 5, and the wire-pulling motor 12 is connected to the motor rotating seat via a wire. The wire-pulling motor 12 can drive the motor rotating seat to rotate, thereby controlling the contact relationship between the rotating wheel 13 and the wire reel 11. That is, when orientation is required, the rotating wheel 13 is controlled to contact the wire reel 11, and after orientation is completed, the rotating wheel 13 is controlled to disengage from the wire reel 11.

[0022] The coil fixing mechanism includes a hollow piston cylinder 9, a push rod shaft 8, and a transmission retaining sleeve 3. The left end of the push rod shaft 8 is connected to the hollow piston cylinder 9, and the right end is tapered. Deformation notches 301 are evenly distributed on the circumference of the right side of the transmission retaining sleeve 3, forming several spring pieces. After the right end of the push rod shaft 8 passes through the transmission retaining sleeve 3, its right end cooperates with the deformation notch of the transmission retaining sleeve 3, so that the spring pieces on the right side of the transmission retaining sleeve 3 can be enlarged or reduced, thereby realizing the locking and unlocking of the coil 11.

[0023] The winding mechanism includes a drive wheel 7, a stepper motor, and a drive belt. The drive wheel 7 is fitted onto the drive sleeve 3, which is mounted on a bracket via double bearings. The stepper motor drives the drive wheel 7 to rotate via the drive wheel and the drive belt, which in turn drives the coil 11 to rotate via the drive sleeve 3, thus achieving the winding function.

[0024] The wire feeding mechanism includes a wire feeding motor 22, an upper rotating wheel 18, a lower rotating wheel 17, and a lower rotating wheel bracket 19. The wire feeding motor 22 is connected to the upper rotating wheel 18 via a transmission shaft 27. The lower rotating wheel 17 is mounted on the lower rotating wheel bracket 19, and the upper rotating wheel 18 and the lower rotating wheel 17 are vertically aligned and closely connected for transmission, thereby realizing the feeding of plastic wire. It also includes a wire feeder 25 and a wire feeding cylinder 23. The plastic wire is threaded through the wire feeder 25, and the wire feeding cylinder 23 is connected to the wire feeder 25. The wire feeder 25 is pushed by the wire feeding cylinder 23 so that the plastic wire is aligned with the positioning hole on the wire reel 11.

[0025] The wire clamping mechanism includes a mini clamp 21, a clamping drive cylinder 29, a wire clamping plate 16, and a wire clamping plate drive cylinder 28. The mini clamp 21 is located at the outlet of the wire feeder 25. The mini clamp 21 is tilted and connected to the clamping drive cylinder 29, so that the plastic wire forms a height difference under the action of the mini clamp 21. The mini clamp 21 can be tilted at 45°. After clamping the plastic wire from the middle, it is pulled back to form two plastic wires that cooperate with the wire clamping plate. The wire clamping piece 16 is positioned above the mini clamp 21 and connected to the wire clamping piece drive cylinder 28. After the plastic wire forms a height difference under the action of the mini clamp 21, the wire clamping piece 16 is driven by the wire clamping piece drive cylinder 28 to clamp the plastic wire into the slot of the wire reel 11.

[0026] In this embodiment, the mini clamp 21 adopts a V-shaped structure, and the wire clamping piece 16 adopts a W-shaped structure. The W-shaped structure can be used to fit the two plastic wires and clamp them into the two adjacent slots on the edge of the wire reel.

[0027] The cutting mechanism includes a pneumatic shear 14 and a pneumatic shear drive cylinder 32. The pneumatic shear 14 is positioned above the outlet of the wire feeder. The pneumatic shear drive cylinder 32 is connected to the pneumatic shear 14 and drives the pneumatic shear 14 to move up and down, enabling the pneumatic shear 14 to actively cut.

[0028] The feeding mechanism includes a pusher rod 6, a feeding cylinder 33, and a feeding track 10. The pusher rod 6 is located on one side of the transmission clamp sleeve 3 and is connected to the feeding cylinder 33. The feeding track 10 is located below the end of the transmission clamp sleeve 3 and is used for feeding and conveying the wire reel 11. After the winding is cut, the wire reel fixing mechanism is activated, and the wire reel is released from the transmission clamp sleeve 3. The feeding cylinder 33 pushes the pusher rod 6 to detach the wire reel from the transmission clamp sleeve 3 and drop it into the feeding track 10. The feeding track 10 is inclined downwards, and the wire reel 11 is automatically conveyed to the next stage under the action of gravity.

[0029] The wire pushing mechanism includes a T-shaped wire pushing rod 34 and a wire pushing cylinder 26. The wire pushing cylinder 26 is connected to the T-shaped wire pushing rod 34, and during the winding process, the T-shaped wire pushing rod 34 is driven to reciprocate through the wire pushing cylinder 26.

[0030] The reel 11 is an I-shaped reel, including a reel body 1101, positioning holes 1102, winding grooves 1104, and wire clamping grooves 1103.

[0031] Working principle: Under the influence of gravity, the workpiece falls into the pusher plate along the track. The pusher plate moves forward under the action of the cylinder, sending the coil into the retracting transmission chuck sleeve.

[0032] When the wire spool is inserted into the transmission clip sleeve, the position of the positioning hole is uncertain. In order to put the wire spool in the right position, the top bar is extended forward to the position where the wire spool needs to stop. The wire pulling motor drives the motor rotating seat to rotate, so that the wheel contacts the wire spool. The rotary motor drives the wheel, which in turn drives the reel to rotate until the top bar aligns with the positioning hole. At the beginning, the spool stops rotating, and the wire pulling motor drives the motor rotating seat to rotate, causing the wheel to disengage from the spool; The pull motor pulls and lifts the wire reel, creating space for it to be inserted into the transmission clip sleeve. Under the influence of gravity, the H-beam reel slides into the reel pusher and moves forward under the push of the feeding cylinder, where it is fitted onto the transmission clasp. The hollow piston cylinder drives the push rod shaft to move forward inside the transmission retainer sleeve. At this time, the transmission retainer sleeve is in an open state, thereby locking the coil. The pull wire motor releases the pull wire, causing the rotary motor to fall (rotate), and the wheel in front of the rotary motor contacts the wire reel; The top bar moves forward to the set position, the rotary motor rotates, driving the wheel, which in turn drives the reel to rotate; After the reel rotates to a certain angle, the inner positioning hole and the top bar are firmly engaged, the rotary motor stops rotating, and the reel is now in the correct position. Next, we are ready to load the wire. The upper rotating wheel is driven by the rotation of the wire feeding motor, and the upper rotating wheel drives the lower rotating wheel to feed the wire forward a certain distance. Under the guidance of the wire feeder, the plastic wire is fed into the inner positioning hole of the small I-shaped wire reel. The stepper motor rotates, driving the transmission belt to rotate. At the same time, the pull motor pulls and lifts the top bar to prevent it from contacting the wire reel. During winding, the T-shaped push rod ensures the plastic thread is evenly distributed on the reel. The stepper motor stops rotating when the required number of turns is reached.

[0033] The mini clamp moves forward under the drive of the clamp drive cylinder. Under the action of the mini clamp, a small section of the plastic wire forms a certain bending angle (the mini clamp moves back after clamping the wire to form a "V" shape). At this time, the wire clamp drive cylinder drives the wire clamp to move forward, so that the plastic wire is clamped into the edge of the wire reel. The upper and lower rotating wheels mesh to lock the plastic wire in place and prevent it from coming off. Finally, the pneumatic shears cut the plastic line, and the hollow piston cylinder drives the push rod shaft to move backward inside the transmission retainer sleeve. At this time, the transmission retainer sleeve is in a retracted state. The push cylinder pushes the pusher bar, causing the wire reel to detach from the transmission retainer sleeve and fall into the feeding track.
