[0004] The objective of this invention can be achieved through the following technical solutions:

[0005] An automatic winding device for transformer production includes a base plate, on which a winding mechanism, a drive mechanism, and a linkage mechanism are provided.

[0006] The winding mechanism includes a mounting plate that is slidably connected to the base plate, a rotating shaft that is rotatably connected to the mounting plate, a baffle that is fixed to one end of the rotating shaft, a winding rod that is coaxial with the rotating shaft that is fixed to the baffle, and an iron core that can be sleeved and fixed on the winding rod.

[0008] Furthermore, a wire threading seat is provided on the upper end of the base plate, and a cutting mechanism is provided on one side of the wire threading seat. The cutting mechanism includes a fixing frame fixed to the upper end of the base plate, a cylinder fixed on the fixing frame, a connecting plate fixed to the lower end of the drive shaft of the cylinder, and a cutter fixed to the lower end of the connecting plate. A clearance groove is provided on the wire threading seat, and the cutter can reach the clearance groove under the drive of the cylinder and cut the copper wire.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] like Figure 1-3 As shown, an automatic winding device for transformer production includes a base plate 1. A winding mechanism 2 is disposed on the upper end of the base plate 1. The winding mechanism 2 includes a mounting plate 21 slidably connected to the base plate 1. A winding rod assembly 22 is mounted on the mounting plate 21. The winding rod assembly 22 includes a rotating shaft 221 rotatably connected to the mounting plate 21. A baffle 222 is disposed at one end of the rotating shaft 221. A winding rod 223 is fixed on the side of the baffle 222 facing away from the rotating shaft 221. The winding rod 223 is connected to the rotating shaft 221. Shaft 221 is coaxial; a screw 224 is provided at the end of the winding rod 223 away from the baffle 222, and a fixing plate 23 is threaded onto the screw 224. The transformer core can be sleeved on the winding rod 223, and by screwing the fixing plate 23 onto the screw 224, the transformer core can be pressed tightly onto the baffle 222; at this time, by rotating the winding rod assembly 22, and simultaneously controlling the mounting plate 21 to slide along the axial direction of the winding rod assembly 22, the winding action of the transformer can be realized;

[0028] A drive mechanism 3 is provided at the upper end of the base plate 1. The drive mechanism 3 is used to drive the mounting plate 21 to slide along the axial direction of the winding assembly 22; for example Figure 4As shown, the drive mechanism 3 includes a motor 31 fixed to the upper end of the base plate 1. A first connecting rod 32 is fixed on the drive shaft of the motor 31. A connecting seat 211 is provided on the mounting plate 21. A second connecting rod 33 is hinged to the connecting seat 211. The second connecting rod 33 and the second connecting rod 32 are rotatably connected by a connecting pin 34. By controlling the rotation of the motor 31, the mounting plate 21 can slide along the axial direction of the winding rod assembly 22. In this embodiment, when the mounting plate 21 slides to the farthest end, the winding work ends. During the retraction process, the mounting plate 21 does not perform winding action (after the winding is completed, the coil is cut off or the iron core is removed).

[0029] The mounting plate 21 is provided with a linkage mechanism 4. The linkage mechanism 4 is used to realize the linkage between the sliding of the mounting plate 21 and the rotation of the winding rod assembly 22, so that during the winding process, the iron core moves along the axial direction of the winding rod assembly 22 to ensure the tightness of the winding and the consistency of the coil winding.

[0030] like Figure 5 As shown, the winding mechanism 4 includes a first bevel gear 41 fixed on the rotating shaft 221, a first fixed plate 212 provided on the mounting plate 21, a rotating rod 42 rotatably connected to the first fixed plate 212, a second bevel gear 43 fixed on the rotating rod 42, and the second bevel gear 43 meshing with the first bevel gear 41; a rack 45 fixed at the upper end of the base plate 1, and a first gear 44 fixed on the rotating rod 42, the first gear 44 meshing with the rack 45; thereby achieving the following: when the driving mechanism 3 drives the mounting plate 21 to slide, the winding rod assembly 22 rotates synchronously to drive the iron core to rotate, thus completing the winding.

[0031] A wire threading seat 5 is provided at the upper end of the base plate 1. The copper wire passes through the wire threading seat 5 and can be wound around the iron core. A cutting mechanism 6 is provided on one side of the wire threading seat 5. The cutting mechanism 6 is used to cut the copper wire on the wire threading seat 5 to end the winding work of a coil.

[0032] like Figure 6-7 As shown, the shearing mechanism 6 includes a fixed frame 61 fixed to the upper end of the base plate 1, a cylinder 62 fixed on the fixed frame 61, a connecting plate 63 fixed to the lower end of the drive shaft of the cylinder 62, a cutter 64 fixed to the lower end of the connecting plate 63, and a relief groove 51 opened on the wire threading seat 5. The cutter 64 can reach the relief groove 51 under the drive of the cylinder 62 and cut the copper wire.

[0033] A second fixing plate 213 is provided on the upper end of the mounting plate 21, and a second gear 24 is fixed on the rotating shaft 221. A limit mechanism 7 is provided on the mounting plate 21. The limit mechanism 7 can engage with the second gear 24 to limit the rotation of the rotating shaft 221. Due to the existence of the linkage mechanism 4, the limit mechanism 7 can limit the rotation of the winding rod 223 and also limit the sliding of the mounting plate 21, so as to avoid damage near the copper wire cut when the shearing mechanism 6 is working, due to the rotation or sliding of the iron core.

[0034] like Figure 8 As shown, the limiting mechanism 7 includes a lifting rod 71 that can be raised and lowered. A locking rod 72 is slidably connected to the lower end of the lifting rod 71. The locking rod 72 passes through the second fixing plate 213 in the vertical direction and is slidably connected to the second fixing plate 213. A spring 73 is installed between the locking rod 72 and the lifting rod 71, thereby realizing an elastic connection between the locking rod 72 and the lifting rod 71. When the lifting rod 71 descends, it can drive the lower end of the locking rod 72 to engage with the two adjacent teeth of the second gear 24, thereby restricting the rotation of the rotating shaft 221. Furthermore, after the lower end of the locking rod 72 engages with the two adjacent teeth of the second gear 24, the lifting rod 71 can continue to descend due to the connecting action of the spring 73.

[0035] The limiting mechanism 7 also includes a fixed rod 74 fixed on one side of the connecting plate 63. A T-shaped groove is provided on the fixed rod 74. A connecting rod 75 is fixed on one side of the lifting rod 71. One end of the connecting rod 75 cooperates with and slides with the T-shaped groove on the fixed rod 74. The sliding direction is the axial direction of the winding rod assembly 22.

[0036] Furthermore, when the connecting plate 63 is at its highest position (the cutter is away from the copper wire), the locking lever 72 just moves away from the second gear 24 in the vertical direction; when the connecting plate 63 is lowered to cut the copper wire, the locking lever 72 engages with the two adjacent teeth of the second gear 24; thus, before the cutter 64 acts on the copper wire, the rotation and sliding of the iron core are restricted by the mechanical mechanism, preventing the cutter 64 from causing damage to the area near the copper wire cut.

[0037] Working principle:

[0038] By setting a winding mechanism 2 on the base plate 1 and a driving mechanism 3 on one side of the winding mechanism 2 to drive the movement of the iron core, and by setting a linkage mechanism 4 on the mounting plate 21 to achieve simultaneous movement and rotation of the iron core, the automatic winding action of the iron core is realized. Compared with the manual winding in the prior art, the production efficiency is greatly improved. By setting a shearing mechanism 6 on one side of the wire threading seat 5 and setting a limiting mechanism 7 to control the timing of shearing, the movement and sliding of the iron core are restricted by the mechanical mechanism before the cutter 64 acts on the copper wire, preventing the cutter 64 from causing damage to the area near the copper wire cut.
