Description

Technical Field

[0001] This utility model relates to the field of silicon steel coil processing technology, and in particular to a surface treatment device for motor stators. Background Technology

[0002] Silicon steel sheets are a soft magnetic alloy of silicon and iron with extremely low carbon content. Adding silicon can increase the resistivity and maximum permeability of iron. They are mainly used to make rotors and stators of various electric motors.

[0003] After receiving silicon steel coils, the factory first uses a transformer silicon steel coil slitting production line to cut them into transformer cores. After cutting, the silicon steel sheets need to be cleaned and dried. However, burrs often appear on the surface of the cut silicon steel sheets. Therefore, it's necessary to first identify and remove these burrs before sending them for cleaning. Currently, factories often rely on visual inspection by personnel, directly observing the surface of the silicon steel coils to look for potential burrs. This results in burrs hidden inside the coils going undetected, leading to errors. Furthermore, manual polishing is inefficient, and polishing burrs from the inner rings of the coils is particularly difficult. In addition, manual inspection cannot be done in real time, resulting in significant time wasted before the silicon steel coils are sent for cleaning, leading to inefficiency and wasted manpower. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a surface treatment device for motor stator.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a surface treatment device for motor stator, the innovation of which is: including an unwinding roller, a detection structure, a deburring structure, a cleaning structure and a take-up roller arranged in sequence;

[0006] An unwinding roll on which a silicon steel coil is mounted;

[0007] A take-up roller, used for winding silicon steel sheets;

[0008] The detection structure includes an upper detection group and a lower detection group. The upper detection group is located on the top surface of the silicon steel sheet at the two sides of its width, and the lower detection group is located on the bottom surface of the silicon steel sheet at the two sides of its width.

[0009] The deburring structure includes a horizontally arranged deburring roller and a deburring roller. The length direction of both the deburring roller and the deburring roller is consistent with the width direction of the silicon steel sheet. The deburring roller is fixedly installed above the silicon steel sheet, and the deburring roller is vertically installed below the deburring roller. A deburring area is left between the deburring roller and the deburring roller to accommodate the silicon steel sheet passing through.

[0010] A cleaning structure is provided between the deburring structure and the receiving roller.

[0011] Furthermore, it also includes two supporting vertical plates, which are respectively fixedly installed on both sides of the width of the silicon steel sheet;

[0012] The upper detection group includes an upper fixed plate and two upper sensors. The upper fixed plate is horizontally fixed between the two supporting vertical plates and above the silicon steel sheet. The upper sensors are mounted on the upper fixed plate, and each upper sensor is set vertically downward.

[0013] The lower detection group includes a lower fixed plate and two lower sensors. The lower fixed plate is horizontally fixed between the two supporting vertical plates and located below the silicon steel sheet. The lower sensors are mounted on the lower fixed plate, and each lower sensor is vertically upward.

[0014] By installing sensors on both sides of the top and bottom widths of the silicon steel sheet, comprehensive detection coverage of the silicon steel sheet cut is achieved, resulting in high accuracy of the detection results.

[0015] Furthermore, a fixed seat is provided on the upper rear side of each of the two supporting vertical plates, and the deburring roller is installed on the fixed seat; a sliding groove is also provided on the rear side of the two supporting vertical plates below the fixed seat. The sliding groove is vertically arranged, and a movable seat is movably installed on the sliding groove by a slider. The deburring roller is installed on the movable seat, and the bottom of each of the two movable seats is connected to a lifting drive component.

[0016] When the detection structure detects burrs on the silicon steel sheet, the lifting drive is used to drive the lower burr roller to rise, which works in conjunction with the deburring roller to remove the burrs. When the detection structure detects that there are no burrs on the silicon steel sheet, the lifting drive is used to drive the lower burr roller to fall, so that the upper and lower burr rollers are separated from the silicon steel sheet.

[0017] Furthermore, the lifting drive component includes a U-shaped push rod, a micro motor, and a lead screw. A push block is fixed on both sides of the top of the U-shaped push rod. An inclined groove is provided at the center of the bottom of the same side of the two movable seats. The push block is disposed in the inclined groove, and the top of the push block is provided with an inclined surface with the same inclination as the inclined groove. The lead screw is rotatably disposed at the output end of the micro motor, and the U-shaped push rod is slidably disposed on the lead screw.

[0018] By using a micro motor to drive the lead screw to rotate, the U-shaped push rod is raised or lowered, which in turn raises and lowers the movable seat, ultimately achieving precise raising and lowering of the deburring roller. This avoids excessive movement of the deburring roller and prevents damage to the surface of the silicon steel sheet. It is suitable for precise deburring of silicon steel sheets of different thicknesses.

[0019] Furthermore, a dust suction hood is provided on the two support vertical plates between the deburring roller and the deburring roller, and the dust suction hood is set towards the deburring area. While deburring, the dust suction hood is used to pick up the removed burrs in real time, so as to prevent the removed burrs from falling on the ground and improve the cleanliness of the factory's internal processing.

[0020] The advantages of this utility model are:

[0021] In this patent, a detection structure is used to detect the presence of burrs on the surface of silicon steel sheets in real time. When burrs are detected, a deburring roller is driven to rise and work in conjunction with the deburring roller to remove the burrs from the silicon steel sheets. The sheets are then directly sent to the cleaning structure for subsequent cleaning operations. Compared with visual inspection, the detection accuracy is higher, avoiding the errors inherent in manual inspection. The deburring structure replaces manual grinding, improving grinding efficiency and avoiding the situation where it is impossible to accurately grind the inner ring burrs of silicon steel coils during manual grinding. This saves manpower and significantly improves both the processing efficiency and accuracy of the factory, ensuring the accuracy of subsequent motor stator manufacturing.

[0022] 2. By setting sensors on both sides of the top and bottom widths of the silicon steel sheet, comprehensive detection coverage of the silicon steel sheet cut is achieved, resulting in high accuracy of the detection results.

[0023] 3. When the detection structure detects burrs on the silicon steel sheet, the lifting drive is used to drive the lower burr roller to rise, which works in conjunction with the deburr removal roller to remove the burrs. When the detection structure detects that there are no burrs on the silicon steel sheet, the lifting drive is used to drive the lower burr roller to fall, so that the upper and lower burr rollers are separated from the silicon steel sheet.

[0024] 4. A micro motor drives the lead screw to rotate, which in turn moves the U-shaped push rod up or down, thereby raising and lowering the movable seat. This synchronizes the precise raising and lowering of the deburring roller, preventing excessive movement of the deburring roller and avoiding damage to the surface of the silicon steel sheet. This method is suitable for precise deburring of silicon steel sheets of different thicknesses.

[0025] 5. A dust suction hood is also provided on the two support vertical plates between the deburring roller and the deburring roller, and the dust suction hood is set towards the deburring area. The dust suction hood is used to pick up the removed burrs in real time, preventing the removed burrs from being scattered on the ground and improving the cleanliness of the factory's internal processing.

[0032] A silicon steel coil is mounted on the unwinding roller 1 for unwinding the silicon steel coil. The take-up roller 5 is used to take up the silicon steel sheet 7, and two support vertical plates 6 are fixedly installed on both sides of the width of the silicon steel sheet 7.

[0033] The detection structure 2 includes an upper detection group and a lower detection group. The upper detection group is located on the top surface of the silicon steel sheet 7 at the two sides of its width, and the lower detection group is located on the bottom surface of the silicon steel sheet 7 at the two sides of its width.

[0034] The upper detection group includes an upper fixed plate 21 and two upper sensors 22.

The upper sensors 22 are installed on the upper fixed plate 21, and each upper sensor 22 is set vertically downward.

[0035] The lower detection group includes a lower fixed plate and two lower sensors. The lower fixed plate is horizontally fixed between two supporting vertical plates 6 and below the silicon steel sheet 7. The lower sensors are installed on the lower fixed plate, and each lower sensor is set vertically upward.

[0036] In this embodiment, both the upper sensor 22 and the lower sensor are laser displacement sensors. By setting sensors on both sides of the width of the top surface and both sides of the width of the bottom surface of the silicon steel sheet 7, comprehensive detection coverage of the cut of the silicon steel sheet 7 is achieved, and the accuracy of the detection results is high.

[0037] The deburring structure 3 includes a horizontally arranged upper deburring roller 31 and lower deburring roller 32. The length direction of both the upper deburring roller 31 and the lower deburring roller 32 is consistent with the width direction of the silicon steel sheet 7. The upper deburring roller 31 is fixedly installed above the silicon steel sheet 7, and the lower deburring roller 32 can be raised and lowered and installed below the upper deburring roller 31. A deburring area is left between the lower deburring roller 32 and the upper deburring roller 31 to accommodate the silicon steel sheet 7 passing through.

[0038] Cleaning structure 4 is set between deburring structure 3 and receiving roller 5.

[0039] Each of the two supporting vertical plates 6 has a fixed seat 33 on its upper rear side, and the deburring roller 31 is mounted on the fixed seat 33. The two supporting vertical plates 6 also have a sliding groove below the fixed seat 33 on their rear side. The sliding groove is vertically set, and a movable seat 34 is movably mounted on the sliding groove by a slider. The deburring roller 32 is mounted on the movable seat 34, and the bottom of each of the two movable seats 34 is connected to a lifting drive component 35.

[0040] The lower drive motor is installed on the outside of the movable seat 34, and the output end of the lower drive motor is connected to the deburring roller 32. The upper drive motor is installed on the outside of the fixed seat 33, and the output end of the upper drive motor is connected to the deburring roller 31.

[0041] When the detection structure 2 detects burrs on the silicon steel sheet 7, the lifting drive 35 drives the lower burr roller 32 to rise, which works in conjunction with the deburr roller 31 to remove the burrs. When the detection structure 2 detects that there are no burrs on the silicon steel sheet 7, the lifting drive 35 drives the lower burr roller 32 to fall, so that the upper and lower burr rollers 32 are separated from the silicon steel sheet 7.

[0042] The lifting drive component 35 includes a U-shaped push rod 351, a micro motor 352, and a lead screw 353. A push block 354 is fixed on both sides of the top of the U-shaped push rod 351. An inclined groove 355 is provided in the center of the bottom of the same side of the two movable seats 34. The push block 354 is set in the inclined groove 355, and the top of the push block 354 is provided with an inclined surface with the same inclination as the inclined groove 355.

The lead screw 353 is horizontally set between the two vertical plates, and a bearing is also provided between the lead screw 353 and the vertical plate. The U-shaped push rod 351 is slidably set on the lead screw 353.

[0043] The micro motor 352 drives the lead screw 353 to rotate, which in turn drives the U-shaped push rod 351 to rise or fall, thereby raising and lowering the movable seat 34. Finally, the deburring roller 32 is raised and lowered in sync, avoiding excessive movement of the deburring roller 32 and preventing damage to the surface of the silicon steel sheet 7. This method is suitable for the precise deburring of silicon steel sheets 7 of different thicknesses.

[0044] A dust suction hood is also provided on the two supporting vertical plates 6 between the deburring roller 31 and the deburring roller 32. The dust suction hood is set towards the deburring area. The dust suction hood is connected to the vacuum cleaner. While deburring, the dust suction hood is used to pick up the removed burrs in real time, so as to prevent the removed burrs from falling on the ground and improve the cleanliness of the factory's internal processing.

[0045] The working principle of this patent:

[0046] In this patent, the detection structure 2 is used to detect in real time whether there are burrs on the surface of the silicon steel sheet 7. When the detection structure 2 detects that there are burrs on the silicon steel sheet 7, the lifting drive 35 drives the deburring roller 32 to rise, which works in conjunction with the deburring roller 31 to remove the burrs. When the detection structure 2 detects that there are no burrs on the silicon steel sheet 7, the lifting drive 35 drives the deburring roller 32 to fall, so that the upper and lower deburring rollers 32 are separated from the silicon steel sheet 7. Then the silicon steel sheet 7 is sent to the cleaning structure 4 for subsequent cleaning operations. Compared with visual inspection, the detection accuracy is high, avoiding the errors that exist in manual visual inspection. The deburring structure 3 replaces manual grinding, improving grinding efficiency and avoiding the situation that cannot accurately grind the inner ring burrs of silicon steel coils during manual grinding. It saves manpower and significantly improves the efficiency and accuracy of motor processing in the factory.
