[0049] An insulating tape wrapping device for a transformer, comprising a tape conveying module 1, a tape wrapping module 2 and a tape cutting module 3;

[0050] The tape conveying module 1 includes a tape unwinder 11 and a tape stretching assembly 12; the tape unwinder 11 is provided with a tape outlet 130; the tape stretching assembly 12 includes a tape clamp 121; the tape wrapping module 2 includes a driving assembly 21, a pushing assembly 24, two mounting plates 22 and two rotating shafts 23; the tape cutting module 3 includes a blade 33;

[0051] The tape unwinding machine 11, the tape stretching assembly 12 and the tape cutting module 3 are respectively installed on the top surface of the frame; the tape clamp 121 can reciprocate along the X direction, and the clamping opening of the tape clamp 121 is horizontally oriented toward the tape outlet 130;

[0052] The two rotating shafts 23 are mounted on the two mounting plates 22 respectively; the two mounting plates 22 are located between the tape clamp 121 and the tape outlet 130; the two rotating shafts 23 extend along the Y direction, one end of the two rotating shafts 23 is arranged at a distance, and the other end of the two rotating shafts 23 is respectively connected to the output end of the driving assembly 21;

[0053] The two mounting plates 22 are respectively connected to the output ends of the pushing assembly 24; the tape clamp 121 is located between the two rotating shafts 23 and below the two rotating shafts 23;

[0054] The tape cutting module 3 is mounted between the rotating shaft 23 and the tape outlet 130 . The blade 33 can reciprocate along the Y direction, and the cutting edge of the blade 33 faces the tape outlet 130 .

[0055] like Figure 1 and Figure 2 As shown, when the insulating tape wrapping device for the transformer of the utility model is in operation, the output end of the insulating tape 431 is output from the tape output port 130 through the tape unwinding machine 11, and the tape clamp 121 moves to the tape output port 130 along the X direction. The tape clamp 121 clamps the output end of the insulating tape 431 and then retracts to its original position, so that the unfolded insulating tape 431 is located between the two rotating shafts 23, and then the magnetic core original 430 that needs to be wrapped with the insulating tape is placed on the insulating tape 431 between the two rotating shafts 23 by the manipulator, and then the pushing assembly 24 pushes the two mounting plates 2 2 are brought closer together, so that the two rotating shafts 23 clamp the two ends of the magnetic core original 430, and then the blade 33 moves along the Y direction and cuts the insulating tape 431 at the tape outlet 130, and the blade 33 moves in the reverse direction along the Y direction and resets, and then the driving component 21 drives the two rotating shafts 23 to rotate half a circle in the forward direction and then rotate half a circle in the reverse direction, so that the insulating tape 431 is wrapped around the outer peripheral surface of the magnetic core original 430, and finally the magnetic core original 430 wrapped with the insulating tape 431 is taken away by the robot, and the pushing component 24 drives the two mounting plates 22 to reset, that is, one operation cycle of wrapping the insulating tape is completed.

[0056] Furthermore, the tape wrapping module 2 further includes a support assembly 26; the support assembly 26 includes a support seat 261, a roller 263, a roller mounting frame 264 and two support rods 262;

[0057] The support base 261 is vertically movably mounted between the two mounting plates 22; the two support rods 262 are erected.

[0058] The bottom ends of the two support rods 262 are fixed to the top surface of the support base 261, and the top ends of the support rods 262 are close to the bottom surface of the rotary shaft 23; the two support rods 262 are arranged at intervals in the X direction between the two mounting plates 22.

[0059] Both sides of the roller mounting frame 264 are fixed to the middle parts of the two support rods 262; the roller 263 is rotatably mounted on the top of the roller mounting frame 264; the top surface of the roller 263 is close to the bottom surface of the rotary shaft 23, and the central axis of the roller 263 and the central axes of the two rotary shafts 23 are located in the same vertical plane.

[0060] As Figure 4 shown, during the process of the tape clip 121 retracting to its original position after clamping the output end of the insulating tape 431, when the tape clip 121 passes through the gap between the two rotary shafts 23, the support base 261 rises, the top surface of the roller 263 contacts the insulating tape 431, and the insulating tape 431 is flattened.

[0061] After that, the manipulator places the magnetic core component 430 that needs to be wrapped with the insulating tape above the insulating tape 431. The bottom surface of the insulating tape 431 and the top surface of the roller 263 pressed by the gravity of the magnetic core component 430 contact the top ends of the two support rods 262, so that the insulating tape 431 adheres to the bottom surface of the magnetic core component 430. Then the support base 261 descends to prevent the roller 263 and the two support rods 262 from blocking the rotation of the magnetic core component 430. Subsequently, the blade 33 moves along the Y direction to cut the insulating tape 431, and then the remaining steps of wrapping the insulating tape are continued.

[0062] Through the cooperation of the roller 263 and the two support rods 262 with the magnetic core component 430 placed above the insulating tape 431, the insulating tape 431 can adhere to the bottom surface of the magnetic core component 430, improving the flatness of the insulating tape 431 wrapped around the magnetic core component 430, and thus improving the assembly quality of the transformer.

[0063] Furthermore, the tape unwinder 11 includes a vertically mounted plate 110, an unwinding roller 111, a guiding roller 112, a turning roller 113, and a conveying roller 114.

[0064] The vertical mounting plate 110 is vertically arranged on the top surface of the frame; the unwinding roller 111 is installed at the top of the vertical mounting plate 110, and the unwinding roller 111 is installed near the bottom of the vertical mounting plate 110; the turning roller 113 and the conveying roller 114 are installed in the middle of the vertical mounting plate 110 and are arranged at intervals in the X direction; the unwinding roller 111, the guiding roller 112, the turning roller 113 and the conveying roller 114 extend along the Y-axis direction respectively.

[0065] As Figure 3 shown, the dotted line in the figure represents the running track of the insulating tape 431, and the arrow on the dotted line represents the conveying direction of the insulating tape 431.

[0066] Install the insulating tape roll on the unwinding roller 111, draw out the end of the insulating tape 431 from the insulating tape roll, and along Figure 3 the running track of the insulating tape 431 in make the insulating tape 431 bypass the guiding roller 112, the turning roller 113 and the conveying roller 114 in sequence, and then convey it to the tape outlet 130.

[0067] Furthermore, the tape unwinding machine 11 further includes a tensioning roller 116;

[0068] The tensioning roller 116 is installed on the vertical mounting plate 110 in a liftable manner. The tensioning roller 116 extends along the Y-axis direction, and the tensioning roller 116 is located between the turning roller 113 and the conveying roller 114.

[0069] As Figure 3 shown, if the output insulating tape 431 is in a slack state, the blade 33 cannot cut the insulating tape 431 neatly. At this time, the tensioning roller 116 can press the insulating tape 431 between the turning roller 113 and the conveying roller 114 from top to bottom, so that the insulating tape 431 becomes a taut state, and the phenomenon that the cutting port of the insulating tape 431 is not neat can be avoided.

[0070] Furthermore, the tape unwinding machine 11 further includes a force value sensor 115;

[0071] The force value sensor 115 is mounted on the vertical mounting plate 110. The force value sensor 115 is located between the unwinding roller 111 and the guiding roller 112; the sensing end of the force value sensor 115 faces the tensioning roller 116. The force value sensor 115 is used for signal connection with the driver that drives the tensioning roller 116 to lift and lower, and the sensing end of the force value sensor 115 is used for contacting the insulating tape 431 passing by the side of the force value sensor 115.

[0072] As Figure 3As shown, the sensing end of the force value sensor 115 contacts the passing insulating tape 431. By detecting the force value on the sensing end of the force value sensor 115, it can be confirmed whether the insulating tape 431 is in a relaxed state or a taut state.

[0073] When the force value sensor 115 detects and confirms that the insulating tape 431 is in a relaxed state, the force value sensor 115 sends a signal to the driver of the driving tensioning roller 116. The driver starts and drives the tensioning roller 116 to move downward from top to bottom to press the insulating tape 431 located between the turning roller 113 and the conveying roller 114, making the insulating tape 431 become taut; during the downward movement of the tensioning roller 116, when the force value sensor 115 detects and confirms that the insulating tape 431 becomes taut, the force value sensor 115 sends a signal to the driver of the driving tensioning roller 116 again, and the driver shuts down, causing the tensioning roller 116 to stop moving downward.

[0074] Furthermore, the tape conveying module 1 further includes a tape pressing assembly 13;

[0075] The tape pressing assembly 13 includes a pressing head member 131 and a pressing groove member 132;

[0076] The pressing head member 131 and the pressing groove member 132 are installed on the vertically installed plate 110 in an up-and-down opposite manner, and the pressing head member 131 can move up and down;

[0077] The pressing head member 131 and the pressing groove member 132 are located on one side of the conveying roller 114 facing the rotating shaft 23, and the conveying roller 114 is located between the pressing head member 131 and the pressing groove member 132;

[0078] The bottom of the pressing head member 131 is provided with a downward protruding pressing head 1311, and the top surface of the pressing groove member 132 is provided with a downward concave pressing groove 1321. The pressing head 1311 and the pressing groove 1321 are vertically aligned. The pressing head 1311 is used to insert into the pressing groove 1321, and the pressing head 1311 and the pressing groove 1321 are in clearance fit;

[0079] When the pressing head 1311 and the pressing groove 1321 are pressed together, the gap between the pressing head member 131 and the pressing groove member 132 facing the rotating shaft 23 is the tape outlet 130.

[0080] As Figure 1 and Figure 3As shown, before the blade 33 moves in the Y direction and cuts the insulating tape 431, after the tape clip 121 retracts to its original position after clamping the output end of the insulating tape 431 and the insulating tape 431 is in a taut state, the indenter 131 is driven by a driver to move downward, so that the indenter 1311 presses the lower insulating tape 431 tightly in the indentation groove 1321, and then the blade 33 moves in the Y direction to cut the insulating tape 431. In this way, not only can the cut of the insulating tape 431 by the blade 33 be ensured to be neat, but also the output end of the insulating tape 431 can be retained at the tape outlet 130; when the insulating tape 431 needs to be stretched between the two rotating shafts 23 subsequently, as long as the tape clip 121 is moved to the tape outlet 130, the output end of the insulating tape 431 can be clamped, thus improving the operation efficiency of wrapping the insulating tape.

[0081] Further, the pushing assembly 24 includes a pusher 241, a pusher mounting bracket 242, and a plurality of guide rods 243;

[0082] The pusher 241 is mounted on the pusher mounting bracket 242; the output end of the pusher 241 extends in the Y direction, and the output end of the pusher 241 is connected to the plate surface of the adjacent mounting plate 22; both ends of the guide rod 243 are respectively connected to the plate surfaces of the two mounting plates 22 corresponding to the opposite sides of the pusher 241.

[0083] As Figure 4 shown, by pushing the mounting plate 22 to slide along the guide rod 243 by the pusher 241, the moving stability of the two rotating shafts 23 can be improved, and the alignment accuracy of the two rotating shafts 23 can be ensured, thereby improving the rotational stability of the magnetic core element 430 between the two rotating shafts 23 and the wrapping quality of the insulating tape 431.

[0084] Figure 4 The scheme shown adopts two pushers 241, and each mounting plate 22 is correspondingly provided with a pusher 241.

[0085] The scheme of fixedly arranging one of the mounting plates 22 can also be adopted. By pushing the other mounting plate 22 to slide along the guide rod 243 by one pusher 241, the two mounting plates 22 are brought closer. The pusher 241 can preferably use a cylinder.

[0086] Further, the driving assembly 21 includes a driving motor 211, a transmission rod 212, two transmission belts 214, and a plurality of transmission wheels 213;

[0087] The driving motor 211 is installed at the bottom of one of the pusher mounting brackets 242; the transmission rod 212 extends in the Y direction, one end of the transmission rod 212 is connected to the output end of the driving motor 211, and the other end of the transmission rod 212 sequentially passes through the plate surfaces of the two mounting plates 22; two transmission wheels 213 are sleeved at both ends of the transmission rod 212; the other end of the rotating shaft 23 passes through the corresponding mounting plate 22, and the other ends of the two rotating shafts 23 are respectively sleeved with two other transmission wheels 213;

[0088] Two transmission wheels 213 that are close to the plate surface of the same mounting plate 22 are vertically opposite to each other. The transmission belt 214 is sleeved on the outer peripheral surfaces of the two vertically opposite transmission wheels 213, and the transmission belt 214 meshes with the outer peripheral surfaces of the corresponding two transmission wheels 213.

[0089] As Figure 4 shown, the driving motor 211 drives the transmission rod 212, the two transmission belts 214 and the multiple transmission wheels 213 to rotate synchronously, so that the two rotating shafts 23 can be driven to rotate synchronously by the corresponding two transmission wheels 213.

[0090] Further, the driving assembly 21 further includes at least one travel sensor 215;

[0091] The travel sensor 215 is installed on the side surface of the mounting plate 22. The travel sensor 215 is a wheel-type travel sensor, and the wheel surface of the measuring wheel of the travel sensor 215 is in frictional contact with the outer peripheral surface of the adjacent transmission belt 214;

[0092] The travel sensor 215 is signal-connected to the driving motor 211.

[0093] As Figure 4 shown, when the driving motor 211 starts and drives the transmission belt 214 to rotate, the measuring wheel rotates with the corresponding transmission belt 214 and triggers the travel sensor 215. The travel sensor 215 detects and calculates the running distance of the transmission belt 214 through the measuring wheel. When the travel sensor 215 confirms that the transmission wheel 213 has rotated half a turn, the travel sensor 215 sends a signal to the driving motor 211. After receiving the signal, the driving motor 211 switches the rotation direction and drives the transmission belt 214 to rotate in the reverse direction. The travel sensor 215 detects and calculates the reverse running distance of the transmission belt 214 through the measuring wheel. When the travel sensor 215 confirms that the transmission wheel 213 has rotated half a turn in the reverse direction, the travel sensor 215 sends a signal to the driving motor 211 again. After receiving the signal again, the driving motor 211 stops running.

[0094] Further, the tape cutting module 3 further includes a pneumatic assembly 32 with a telescopic end and a cutting module mounting bracket 31;

[0095] The top end of the blade 33 extends obliquely upward, and the bottom end of the blade 33 is mounted on the telescopic end of the pneumatic component 32 . The pneumatic component 32 is mounted on the top of the cutting module mounting frame 31 .

[0096] like Figure 5 In the illustrated embodiment, the pneumatic assembly 32 drives the blade 33 to move, which can improve the operating stability of the blade 33 and thus the uniformity of the incision of the insulating tape.

[0097] Preferably, the tape stretching assembly 12 is a two-finger clamp equipped with the tape clamp 121, and the tape clamp 121 is a flexible clamp.

[0098] Preferred embodiments, such as Figure 1 As shown, it also includes a magnetic core placement rack 5, which is mounted above the tape cutting module 3.
