[0027] Step 1: Insert the motor lead sleeve sheet: The motor lead sleeve sheet is inserted into the guide groove formed by the Z-shaped pressure plate on the left and the horizontal support seat, and then the pull rod is pulled upward to drive the slide plate to move upward, thereby driving the pressure roller to move upward and increase the gap between the pressure roller and the driving roller, and the motor lead sleeve sheet passes through the gap, and then release the pull rod;

[0028] Step 2, loosening the material: first start the third cylinder to drive the first pressing plate to move downward and press the motor lead sleeve sheet, then start the second cylinder to drive the second pressing plate to move downward, the second pressing plate presses the straightened motor lead sleeve sheet into a curved arc state, then the third cylinder and the second cylinder are reset;

[0029] Step 3, receiving and feeding: start the fifth cylinder to extend, drive the sixth cylinder and the guide plate to move to the right, the guide plate moves to the right end to abut against the horizontal support seat, and receives the motor lead sleeve sheet conveyed by the fixed-length conveying assembly;

[0030] Before the end of the motor lead sleeve sheet material is exposed from the left end of the guide plate, the fifth cylinder is started to contract and the sixth cylinder is started to extend, and the guide plate moves leftward until the left end abuts against the slot, and then the end of the motor lead sleeve sheet material is directly inserted into the slot;

[0032] Step 4, start winding: start the first motor to drive the rotating roller to rotate, and wind the motor lead sleeve sheet. As the number of winding turns of the motor lead sleeve sheet increases, the thickness becomes thicker, and the elastic plate presses against the winding tube, driving the elastic plate to gradually move upward, and the elastic plate drives the elastic plate limiter to move up along the horizontal plate;

[0033] Step 5, fixed-length cutting: When the two ultrasonic position sensors know that the length of the motor lead sleeve sheet has reached the set length, the controller controls the second motor to stop and the first cylinder to start, and the first cylinder drives the cutter to move downward to cut the motor lead sleeve sheet, and then the first cylinder is reset; the motor lead sleeve sheet is continuously wound by the rotating roller until it is completely wound, and then the controller controls the first motor to stop, and at this time the slot of the rotating roller faces the transverse guide groove;

[0034] Step 6: Start the upper cylinder and the lower cylinder to drive the upper cylinder and the lower electrode to move toward each other, perform end welding on the motor lead sleeve, and then reset the upper cylinder and the lower cylinder;

[0035] Step seven, start the fourth cylinder, the fourth cylinder drives the push ring to move forward by connecting the inclined plate, and the push ring pushes the motor lead sleeve forward to achieve material unloading; then the fourth cylinder resets.

[0036] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention can realize that after cutting and before the end of the motor lead sleeve sheet is exposed, the guide plate moves to the right to the right end and abuts against the horizontal support seat, and receives the motor lead sleeve sheet conveyed by the fixed-length conveying component to avoid curling and warping of the end. At the same time, before the end of the motor lead sleeve sheet is exposed at the left end of the guide plate, the guide plate moves to the left to the left end and abuts against the slot, and subsequently guides the end of the motor lead sleeve sheet to be directly inserted into the slot, and has good contact with the winding structure to avoid curling and displacement of the end, so that the two ends of the motor lead sleeve after winding are flat, and the subsequent ends are not easy to explode after welding, thereby ensuring the yield rate.

[0088] Embodiment 2: In some embodiments, Figure 1 , Figure 3 and Figure 5 As shown, as a preferred embodiment of the present invention, a method for using a motor lead sleeve welding device comprises the following steps:

[0089] Step 1: Insert the motor lead sleeve sheet: The motor lead sleeve sheet is inserted into the guide groove formed by the Z-shaped pressing plate 65 and the horizontal support seat 66 on the left, and then the pull rod 67 is pulled upward to drive the slide plate 64 to move upward, thereby driving the pressure roller 62 to move upward and increase the gap between the pressure roller 62 and the driving roller 68, and the motor lead sleeve sheet passes through the gap, and then the pull rod 67 is released;

[0090] Step 2, loosening the material: first start the third cylinder 73 to drive the first pressing plate 74 to move downward and press the motor lead sleeve sheet, then start the second cylinder 71 to drive the second pressing plate 75 to move downward, and the second pressing plate 75 presses the stretched motor lead sleeve sheet into a curved arc state to loosen the material, and then the third cylinder 73 and the second cylinder 71 are reset;

[0091] Step 3, receiving and feeding: start the fifth cylinder 311 to extend, drive the sixth cylinder 312 and the guide plate 34 to move rightward, the guide plate 34 moves rightward to the right end and abuts against the horizontal support seat 66, and receives the motor lead sleeve sheet conveyed by the fixed-length conveying assembly 6; before the end of the motor lead sleeve sheet is exposed from the left end of the guide plate 34, start the fifth cylinder 311 to contract and the sixth cylinder 312 to extend, the guide plate 34 moves leftward to the left end and abuts against the slot 37, and subsequently guides the end of the motor lead sleeve sheet to be directly inserted into the slot 37; then start the sixth cylinder 312 to contract, the guide plate 34 is located between the rotating roller 38 and the horizontal support seat 66, and plays a receiving role;

[0092] Step 4, start winding: start the first motor 35 to drive the rotating roller 38 to rotate, and wind the motor lead sleeve sheet. As the number of winding turns of the motor lead sleeve sheet increases, the thickness becomes thicker, and the elastic plate 31 presses on the winding tube, driving the elastic plate 31 to gradually move up. The elastic plate 31 drives the elastic plate limiter 310 to move up along the horizontal plate 39 to ensure that the winding tube is always pressed but the pressing force is moderate. At the same time, for motor lead sleeves of different thicknesses, the fixing piece 314 can be removed to adjust the position of the cross bar 32 in the horizontal movable groove 313 to achieve adaptive adjustment;

[0093] Step 5, fixed-length cutting: When the two ultrasonic position sensors 55 learn that the length of the motor lead sleeve sheet has reached the set length, the controller controls the second motor 63 to stop and the first cylinder 51 to start, and the first cylinder 51 drives the cutter 53 to move downward to cut the motor lead sleeve sheet, thereby achieving a fixed-length cutting effect on the motor lead sleeve sheet; then the first cylinder 51 is reset; the rotating roller 38 continues to rewind until the motor lead sleeve sheet is completely rewound, and the controller controls the first motor 35 to stop, at which time the slot 37 of the rotating roller 38 faces the transverse guide groove 36;

[0094] When the second motor 63 stops, the next loosening process (step 2) can be completed synchronously.

[0095] Step 6: Start the upper cylinder 44 and the lower cylinder 46 to drive the upper cylinder 44 and the lower electrode 45 to move toward each other, and perform end welding on the motor lead sleeve. At this time, the upper cylinder 44 and the lower electrode 45 are located in front of the rotating roller 38; then the upper cylinder 44 and the lower cylinder 46 are reset;

[0096] Step 7, start the fourth cylinder 91, the fourth cylinder 91 drives the push ring 93 to move forward through the connecting inclined plate 92, and the push ring 93 pushes the motor lead sleeve to move forward to achieve material unloading; then the fourth cylinder 91 is reset;

[0097] During the process of completing step 6 and step 7, the next receiving and feeding process (step 3) can be carried out synchronously. In this process, before the left end of the guide plate 34 abuts against the slot 37, the fourth cylinder 91 has completed the reset process in advance.
