A turntable motor for driving the turntable 301 to rotate is provided at the center of the back of the turntable 301, and the turntable motor drives the turntable 301 to rotate. The winding and winding changing actions are as follows:

[0041] The first step is to start the motor of the turntable 301. The turntable 301 rotates until the two wire roller shafts 302 are horizontal and stop. Install the empty winding roller 1 at the winding changing station on the right, start the turntable motor, rotate the turntable 301 180 degrees clockwise, and the empty winding roller 1 moves to the winding changing station.

[0042] The second step is to start the wire roller motor on the left side, and the wire roller 1 at the winding station is wound and wound. At the same time, the empty winding roller 1 is installed at the winding station on the right side in preparation.

[0043] In the third step, after the wire roller of the winding station is wound, the turntable motor is started, the turntable 301 rotates 180 degrees clockwise, and the full winding wire roller 1 of the winding station is exchanged with the empty winding wire roller 1 of the winding changing station. The wire connected to the full winding wire roller 1 is between the winding station and the winding changing station.

[0044] In the fourth step, the wire cutting mechanism 4 is pressed down to cut off the wire connected to the full winding roller 1, forming the wire tail of the full winding roller 1 and the wire head of the empty winding roller 1;

[0045] In the fifth step, the thread end fixing mechanism 5 fixes the thread tail of the full thread winding roller 1 to the full thread winding roller 1 , and fixes the thread head of the empty thread winding roller 1 to the empty thread winding roller 1 .

The piston rod of the scissor lifting cylinder 401 faces downward and is connected to a pneumatic scissors 402.

[0047] In the above embodiments, specifically, the downward-pressing wire-cutting mechanism 4 includes a scissors lifting cylinder 401 and a pneumatic scissors 402 installed on the piston rod of the scissors lifting cylinder 401. When the scissors lifting cylinder 401 of the downward-pressing wire-cutting mechanism 4 is started, the pneumatic scissors 402 moves downward to cut the wire connected to the full winding roller 1.

[0048] Further, refer to Figure 1 and Figure 5 The thread end fixing mechanism 5 includes a tape delivery component 501, a left tape pressure roller component 502 located just above the winding station and a right tape pressure roller component 503 located just above the roll changing station; the tape delivery component 501 includes a second frame 5011 located in front of the main frame 2, and a left tape machine 5012 and a right tape machine 5013 are relatively arranged on the second frame 5011; the left tape machine 5012 and the right tape machine 5013 can spit out a set length of tape 5014 and cut it; the tape delivery component 501 is used to receive the tape 5014 spit out by the left tape machine 5012 and the right tape machine 5013 and deliver the tape 5014 to the top of the line connecting the winding station and the roll changing station; the left tape pressure roller component 502 includes a left pressure roller component 503 and a right pressure roller component 504 ... The roller lifting cylinder 5021, the cylinder body of the left pressure roller lifting cylinder 5021 is fixedly connected to the main frame 2, the piston rod of the left pressure roller lifting cylinder 5021 is downward and a left pressure roller 5022 is provided; the right tape pressure roller assembly 503 includes a right pressure roller lifting cylinder 5031, the cylinder body of the right pressure roller lifting cylinder 5031 is fixedly connected to the main frame 2, the piston rod of the right pressure roller lifting cylinder 5031 is downward and a right pressure roller 5032 is provided; the left tape pressure roller assembly 502 is used to stick the beginning of the empty winding roller 1 with the tape 5014 pasted on it to the empty winding roller 1 of the winding station; the right tape pressure roller assembly 503 is used to stick the end of the full winding roller 1 with the tape 5014 pasted on it to the full coiled wire roller 1 of the winding changing station.

[0049] In the above embodiment, the cut wire forms the tail of the full wire roll 1 and the head of the empty wire roll 1. The tail of the full wire roll 1 needs to be fixed, and the head of the empty wire roll 1 needs to be fixed on the empty wire roll 1. In this embodiment, preferably, the wire head fixing mechanism 5 includes a tape delivery component 501, a left tape pressing roller component 502 located above the winding station, and a right tape pressing roller component 503 located above the reeling station. After the wire rolls 1 of the reeling station and the reeling station are interchanged, the tape delivery component 501 delivers two sections of tape 5014 to the top of the wire connected to the full wire roll 1, and the downward pressing wire cutting mechanism 4 is started to cut the wire, and at the same time, the two sections of tape 5014 are respectively pasted to the tail end of the wire of the full wire roll 1 and the head of the wire of the empty wire roll 1. At this time, the motor of the wire roller 1 of the reel changing station is started, so that the wire roller 1 of the reel changing station rotates 90 degrees clockwise, and the pressure roller of the right pressure roller 5032 assembly squeezes the right pressure roller 5032 so that the tape 5014 fixes the wire tail of the full wire roller 1. At the same time, the empty wire roller 1 of the winding station is fixing the wire head of the empty wire roller 1. The first step is to start the wire roller motor of the winding station and rotate the wire roller 1 of the winding station counterclockwise by 90 degrees. Since the left pressure roller 5022 of the left pressure roller 5022 assembly squeezes the wire material on the empty wire roller 1, the counterclockwise rotation makes the wire tail of the empty wire roller 1 with the tape 5014 attached to it adhere and fix it on the surface of the wire roller 1; the second step is to start the wire roller motor of the winding station and make the wire roller 1 of the winding station rotate clockwise and rewind normally.

[0050] Further, refer to Figure 4 The left pressure roller 5022 and the right pressure roller 5032 are both horizontally arranged pairs of rollers.

[0051] In the above embodiment, in order to make the tape 5014 fixed more firmly, the left pressure roller 5022 and the right pressure roller 5032 use a pair of rollers to prevent the wire from falling off or moving away from the specified position when the tape 5014 is pasted, so as to make the pasting more secure.

[0052] Further, refer to Figure 5 The tape delivery component 501 also includes a tape pallet lifting cylinder 5015, a pressure head lifting cylinder 5016, and a longitudinal feeding cylinder 5017; the cylinder body of the tape pallet lifting cylinder 5015 is fixedly connected to the second frame 5011, the piston rod of the tape pallet lifting cylinder 5015 is upward and connected to the cylinder body of the longitudinal feeding cylinder 5017, the piston rod of the longitudinal feeding cylinder 5017 is toward the turntable 301 and is connected to the tape pallet 5018; the cylinder body of the pressure head lifting cylinder 5016 is fixedly connected to the second frame 5011, the piston rod of the pressure head lifting cylinder 5016 is downward and connected to the tape pressure head 5019 corresponding to the tape pallet 5018.

[0053] In the above embodiment, specifically, the tape delivery assembly 501 includes a tape support plate 5018, a longitudinal feeding cylinder 5017 and a tape support plate lifting cylinder 5015. The tape support plate 5018 is located below the tape outlets of the left tape machine 5012 and the right tape machine 5013. The tape support plate 5018 supports the tape 5014 spit out from the left tape machine 5012 and the right tape machine 5013. The longitudinal displacement is adjusted by the longitudinal feeding cylinder 5017, and the vertical displacement is adjusted by the tape support plate lifting cylinder 5015. The linear motion in two dimensions can realize that the tape 5014 is delivered to the top of the wire material at the roll changing station and the winding station. In order to make the adhesive tape 5014 ejected from the left adhesive tape machine 5012 and the right adhesive tape machine 5013 reliably adhere to the adhesive tape support plate 5018, a pressure head lifting cylinder 5016 is fixedly connected to the second frame 5011, and a tape pressure head 5019 is installed on the piston rod head of the pressure head lifting cylinder 5016; the tape pressure head 5019 is located above the adhesive tape outlets of the left adhesive tape machine 5012 and the right adhesive tape machine 5013. When the adhesive tape support plate 5018 is below the adhesive tape 5014, the pressure head lifting cylinder 5016 moves downward to press the adhesive tape 5014 onto the adhesive tape support plate 5018. The adhesive tape 5014 does not need to be completely adhered to the adhesive tape support plate 5018, so the front end surface of the adhesive tape support plate 5018 can be located at one-fourth of the adhesive tape 5014, which is also convenient for separating the adhesive tape 5014 from the adhesive tape support plate 5018.
