TECHNICAL FIELD

[0001] Embodiments of the present disclosure relate to the technical field of uncoiling device, in particular to an uncoiling device for stator core production. BACKGROUND

[0002] The stator core is the main structure of the stator part of the motor, which is usually composed of multiple layers of silicon steel sheets. Silicon steel sheets are used because they have good electromagnetic properties, which can effectively conduct and concentrate the magnetic field during motor operation, reducing energy loss and improving motor efficiency and performance.

[0003] Silicon steel sheets are usually packaged in rolls for easy transportation and storage when they leave the factory. During the use and production of stator cores, an uncoiling device is used to unroll the silicon steel sheets into continuous strips or sheets, so that subsequent processes such as punching and stamping can be performed.

[0004] However, during the uncoiling of silicon steel sheets, the installation level or verticality of the uncoiler may deviate, or the surface of the roll may wear out after prolonged use, resulting in uneven friction between the silicon steel sheets and the roll, which may cause the silicon steel sheets to shift or "run off" during uncoiling.

[0033] As shown, Figure 2 It also includes a push assembly, a correction ring one 4, an adjusting assembly, a correction ring two 5 and a positioning assembly, the push assembly is provided with two, the two push assemblies are arranged on the bottom plate 3, the correction ring one 4 is arranged on the push assembly, the push assembly is used to push the correction ring one 4 to adhere to the silicon steel sheet, thereby correcting the silicon steel sheet, the adjusting assembly is arranged on the side of the bottom plate 3, the correction ring two 5 is arranged on the adjusting assembly, the adjusting assembly is used to adjust the position of the correction ring two 5, during feeding, the correction ring two 5 is away from the reel 2, during correcting the silicon steel sheet, the correction ring two 5 adheres to the silicon steel sheet, the positioning assembly is arranged on the bottom plate 3, used to accurately move the correction ring two 5 to the side of the reel 2 when moving the correction ring two 5.

[0034] As shown, Figure 4 The bodies of the correction ring one 4 and the correction ring two 5 are both provided with a plurality of baffles, and the plurality of baffles are connected through the bent rod, and the middle part is hollow, thereby when installing the correction ring one 4, the reel 2 can pass through the middle part of the correction ring one 4, thereby moving the correction ring one 4 to the other end of the reel 2 for subsequent correction.

[0035] After installing the correction ring one 4, then adjust the correction ring two 5 through the positioning assembly and the adjusting assembly, as shown, Figure 3 The adjusting assembly comprises a support cover 9, a reciprocating lead screw 10, a motor two 11, a lead screw nut 12 and a forward moving assembly, the support cover 9 is fixedly installed on the side of the bottom plate 3, the reciprocating lead screw 10 is rotatably installed in the support cover 9, the motor two 11 is installed on the side of the support cover 9, and the motor two 11 is coaxially connected with the reciprocating lead screw 10, the lead screw nut 12 is installed on the reciprocating lead screw 10, the forward moving assembly is arranged on the lead screw nut 12, used to push the correction ring two 5 to move forward, the forward moving assembly comprises a support plate 13, an electric cylinder two 14 and a pushing frame 15, the support plate 13 is fixedly installed on the lead screw nut 12, the electric cylinder two 14 is installed on the support plate 13, the pushing frame 15 is fixedly installed on the output end of the electric cylinder two 14, and the side of the pushing frame 15 is fixedly connected with the side of the correction ring two 5, the positioning assembly comprises a positioning block 16 and a positioning rod 17, the positioning block 16 is fixedly installed on the side of the pushing frame 15, and the side of the positioning block 16 is provided with a positioning groove, the positioning rod 17 is fixedly installed on the bottom plate 3, and the side of the positioning rod 17 is matched with the positioning groove of the positioning block 16.

[0036] Specifically, starting motor 11 causes the output of motor 11 to drive the reciprocating screw 10 to rotate within the support cover 9. It should be noted that the screw nut 12 and the reciprocating screw 10 are connected by a rolling thread transmission. Figure 5 As shown, the inner bottom wall of the support cover 9 is provided with a sliding groove, and the lead screw nut 12 is slidably installed in the sliding groove through the slider. The lead screw nut 12 can move left and right on the reciprocating lead screw 10, thereby driving the push assembly and the second correction ring 5 to move to the positioning groove of the positioning block 16 to contact the positioning rod 17. When the positioning rod 17 is inserted into the positioning groove of the positioning block 16, the center of the second correction ring 5 and the center of the drum 2 are at the same horizontal position. When the mounting plate 6 is installed on the base plate 3, the center of the first correction ring 4 and the center of the drum 2 are at the same horizontal position. At this time, the first correction ring 4, the second correction ring 5 and the drum 2 are at the same horizontal position. When unwinding, the first correction ring 4 and the second correction ring 5 can block both sides of the silicon steel sheet. If the silicon steel sheet deviates, it will be blocked by the first correction ring 4 and the second correction ring 5 to prevent it from deviating out of the drum 2.

[0037] If there is a deviation, the adjusting component of the pushing assembly drives the first correction ring 4 and the second correction ring 5 to squeeze the silicon steel sheet, thus correcting it. The pushing assembly includes a mounting plate 6, an electric cylinder 7, and a connecting plate 8. The mounting plate 6 is detachably mounted on the base plate 3, the electric cylinder 7 is mounted on the mounting plate 6, and the connecting plate 8 is fixedly mounted on the side of the first correction ring 4, with the side of the connecting plate 8 fixedly connected to the output end of the electric cylinder 7. Specifically, when the electric cylinder 7 is activated, its output end pushes the first correction ring 4 forward, and simultaneously, the second electric cylinder 5 is activated. 4. The output end of the electric cylinder 14 drives the push frame 15 to move forward, and the push frame 15 drives the correction ring 5 to move forward. Because the two ends of the positioning groove of the positioning block 16 are open, the side of the positioning rod 17 can slide in the positioning groove of the positioning block 16 when moving forward, thereby avoiding the positioning rod 17 from blocking the correction ring 5 from moving forward. Furthermore, the push frame 15 is set in a U-shape. The correction ring 5 is connected to the electric cylinder 14 through the U-shaped push frame 15, which can drive the correction ring 5 to move forward and also avoid the push frame 15 being blocked by the drum 2 when moving.

[0038] Working principle: when preventing the deviation of the silicon steel sheet from being unwound, first, install the installation plate 6 on the bottom plate 3, so as to install the correction ring one 4 on the side of the winding drum 2, then start the motor two 11, the output end of the motor two 11 drives the reciprocating lead screw 10 to rotate in the support cover 9, drives the lead screw nut 12 and the support plate 13 to move left and right, and then drives the correction ring two 5 to translate, the translation is to the contact positioning of the positioning block 16 on the pusher 15 Positioning rod 17, then when unwinding, the correction ring one 4 and the correction ring two 5 block the two sides of the silicon steel sheet, if the unwinding process is unwound, stop unwinding, start the electric cylinder one 7 and the electric cylinder two 14, the output end of the electric cylinder one 7 and the electric cylinder two 14 drives the correction ring one 4 and the correction ring two 5 to move relatively, so as to extrude the two sides of the silicon steel sheet, and then correct the deviated silicon steel sheet.
