[0020] Example like Figure 1-Figure 13As shown, the present invention provides a four-station motor stator semi-automatic winding device based on the inner winding method, including a chassis 7 and a spindle mechanism 1, a winding mechanism 2, a winding seat mechanism 3, an automatic opening and closing mechanism 4, a waste wire collection mechanism 5 and a tension mechanism 6 arranged above the chassis 7. The spindle mechanism 1 is arranged at the center of the chassis 7 and can move along three directions of X\Y\Z. The winding mechanism 2 is arranged above the winding seat mechanism 3 and is connected to the spindle mechanism 1. The winding mechanism 2 can move up and down and realize a 90° flip of the winding rod 24. The winding seat mechanism 3 can realize a 360-degree rotation, and cooperate with the winding mechanism 2 to realize precise winding of the stator; the automatic opening and closing mechanism 4 and the waste wire collection mechanism 5 are sequentially arranged on one side of the spindle mechanism 1 connected to the winding mechanism 2 and are connected to the winding seat mechanism 3, and the tension mechanism 6 is arranged above the spindle mechanism 1. The automatic opening and closing mechanism 4 opens the opening and closing clamp 34 through the cylinder at the beginning and end of winding to facilitate manual insertion and removal of the stator. The waste wire collection mechanism 5 automatically pulls the wire after the stator is wound, breaks the head and tail wire ends, and then blows the waste wire to the waste wire box 51 through the air pipe for collection. The tension mechanism 6 passes the copper wire through the tensioner 62, and the tensioner 62 applies the winding tension to tighten the wire to achieve the required tension during winding, thereby improving the yield rate. The above mechanisms jointly realize automatic winding, improve work efficiency and product yield rate, and realize simple, efficient and stable winding of stator coil products.

[0021] The spindle mechanism 1 includes a Y-axis moving unit, an X-axis moving unit and a Z-axis moving unit, wherein the Y-axis moving unit is fixedly mounted on the chassis 7 through a fixing plate, the X-axis moving unit is mounted on the Y-axis moving unit through a screw support, the Z-axis moving unit is mounted on the X-axis moving unit through a Z-axis weldment 19, and the Z-axis moving unit is connected to the winding mechanism 2.

[0022] The Z-axis moving unit includes a Z-axis motor 17, a Z-axis synchronous wheel 18 and a Z-axis weldment 19. The Z-axis motor 17 is connected to the Z-axis synchronous wheel 18 through a belt, thereby driving the vertical movement of the Z-axis weldment 19. The X-axis moving unit includes a screw support, an X-axis slide rail 13 fixed on both sides of the screw support, an X-axis screw 11 and an X-axis motor 12. The X-axis screw 11 is provided with an X-axis slider matched with the X-axis slide rail 13. The X-axis motor 12 drives the X-axis screw 11, thereby driving the horizontal movement of the X-axis. The Y-axis moving unit includes a fixed plate, a Y-axis slide rail 14 arranged on both sides of the fixed plate, a Y-axis screw 15 and a Y-axis motor 16. The Y-axis screw 15 is provided with a Y-axis slider matched with the Y-axis slide rail 14. The Y-axis motor 16 drives the Y-axis screw 15, thereby driving the horizontal movement of the Y-axis. Through this mechanism setting, the spindle mechanism 1 can realize movement in three directions and cooperate with the winding mechanism 2 and the winding seat mechanism 3 to achieve precise winding around the stator.

[0023] The winding mechanism 2 includes a fixing part 21 and a winding plate 22 connected to the fixing part 21. Four winding cylinders 23 and winding rods 24 are evenly arranged on the winding plate 22. The four winding cylinders extend and retract synchronously to drive the four winding rods 24 to flip 90 degrees synchronously. The winding nozzle 25 is installed on the winding rod 24 for inserting the copper wire to achieve the function of winding around the stator when winding.

[0024] The winding seat mechanism 3 includes a support plate 31, four indexing motors 32 arranged below the support plate 31, and four stator seats 33 correspondingly arranged above the support plate 31, and an opening and closing clamp 34 is arranged on the stator seat 33. The empty stator is manually placed in the stator seat 33, and the stator seat 33 is driven by the indexing motor 32 to rotate 360 ​​degrees, and cooperates with the spindle mechanism 1 and the winding mechanism 2 to achieve accurate winding of the stator.

[0025] The automatic opening and closing mechanism 4 includes two pressing plates 41 and two pressing rods 42 arranged in parallel between the two pressing plates 41. Four pairs of pressing heads 44 are evenly arranged on the pressing rods 42. A pressing cylinder 43 for driving the pressing heads 44 is arranged on the outer sides of the two pressing plates 41. When the stator needs to be taken out and put in, the cylinder is actuated to press the pressing heads 44 toward the opening and closing clamp 34 in the winding seat mechanism 3, so that the opening and closing clamp 34 is opened.

[0026] The waste wire collecting mechanism 5 includes a waste wire box 51, a flow channel plate 52, an adjustable cylinder 53, an external air pipe 54 and four wire winding assemblies 58. The wire winding assembly 58 is arranged on the guide rod 55 of the adjustable cylinder 53, the flow channel plate 52 is arranged above the wire winding assembly 58, and the waste wire box 51 is arranged below the flow channel plate 52; when the winding mechanism 2 winds the wire head or wire tail on the wire winding assembly 58, the adjustable cylinder 53 of the waste wire collecting mechanism 5 is actuated to tear off the wire head or wire tail, and then the waste wire is blown toward the flow channel plate 52 and flows toward the waste wire box 51 through the external air pipe.

[0027] The winding assembly 58 includes a winding post 56 and a winding cylinder driving the winding post 56. When winding is required, the cylinder moves to extend the winding post 56, so as to facilitate winding by the winding mechanism 2. When the adjustable cylinder 53 in the waste wire collection mechanism 5 moves to tear off the wire head or tail, the winding cylinder 57 of the winding assembly 58 moves to retract, and after the torn wire head or tail falls off, the external air pipe 54 blows the waste wire to the flow channel plate 52 and flows into the waste wire box 51.

[0028] The tension mechanism 6 includes a fixed rod 61 and four sets of tensioners 62 arranged on the fixed rod 61, and the tensioner 62 is fixed on the Z-axis weldment 19 through a fixed plate. Four sets of wire assemblies are also arranged at the front and rear ends of the tensioner 62. The wire assembly mainly guides the copper wire. The rear end wire assembly mainly guides the lead-out copper wire to the wire inlet of the tensioner 62, and the front end wire assembly mainly guides the wire led out from the tensioner 62 to the wire inlet of the winding nozzle 25 of the winding mechanism 2. The tensioner 62 gives the winding tension to tighten the wire to achieve the required tension during winding, and the wire assembly can effectively prevent the wire from bending. The wire assembly includes two wire rods 63 respectively arranged at the front and rear ends of the tensioner 62, and the wire rod 63 is connected to the fixed rod 61 through a wire fixing seat 65. Four sets of wire wheels 64 are arranged on the wire rods 63.

[0029] The above mechanisms are all installed on the chassis 7. The chassis 7 is welded as a whole and then painted. It is neat and beautiful. When the machine is running at high speed, the whole machine is still stable and does not shake. An aluminum profile frame 8 is set above the chassis 7 and connected to the chassis 7 by screws. Acrylic windows and sheet metal doors are set around the chassis 7 respectively. After opening, the machine operation status can be clearly seen. It is closed during normal operation to protect the operator.

[0030] When starting to work, the cylinder of the automatic opening and closing mechanism 4 moves to extend and open the opening and closing clamp 34 on the winding seat device, and put the unwound stator into the stator seat 33 in the winding seat mechanism 3, and the cylinder moves to retract and close the opening and closing clamp 34 on the winding seat mechanism 3. The spindle mechanism 1 drives the winding mechanism 2 to the top of the winding column 56 of the automatic opening and closing mechanism 4, and the cylinder in the winding mechanism 2 moves to extend, and the winding rod 24 equipped with the winding nozzle 25 is turned 90 degrees to a horizontal state, and then the copper wire led out from the winding nozzle 25 is manually pulled, so that the winding device can wind the copper wire on the winding column 56. Then the cylinder in the winding mechanism 2 retracts, and the cylinder in the winding mechanism 2 retracts, and the winding rod 24 is flipped 90 degrees again. After it becomes vertical, the spindle mechanism 1 drives the winding mechanism 2 to move above the stator seat 33, and the Z-axis motor 17 in the spindle mechanism 1 drives the winding mechanism 2 to realize up and down reciprocating motion and cooperates with the indexing motor 32 in the winding seat mechanism 3 to reciprocate to realize the winding of the first slot in the stator. This reciprocating motion can complete the winding of the stator. When the winding of the first slot is completed, the cylinder in the mechanism moves at the same time to tear off the copper wire on the winding column 56. When the stator winding is completed, the spindle mechanism 1 drives the winding mechanism 2 to the top of the winding column 56 of the automatic opening and closing mechanism 4, and at the same time, the cylinder on the winding mechanism 2 extends to make the winding rod 24 horizontal, and the winding is carried out around the winding column 56. After the winding is completed, the cylinder of the winding mechanism in the automatic opening and closing mechanism 4 retracts, the copper wire falls off, and the external air pipe 54 blows air to blow the torn copper wire toward the flow channel plate 52 and flows to the waste wire box 51.

[0031] Therefore, the present invention adopts the above-mentioned four-station motor stator semi-automatic winding device based on the inner winding method, which saves labor costs and improves work efficiency, and realizes simple, efficient and stable winding of the stator coil.
