[0026] The present invention is further described in detail below with reference to specific embodiments.

[0027] like Figure 1-7 As shown, a large magnetic ring inductor enameled wire pin stripping knife 10 includes a knife seat 1, a knife rod 2 and a stripping knife member 3. The stripping knife member 3 includes a mounting portion 31 and a knife head 32. The knife head 32 has a stripping knife opening 321 with an opening opposite to the pin. The stripping knife opening 321 is provided with a blade 322 that contacts the pin axially in parallel during operation. The knife head 32 has an outer end face 33 that can contact the inductor base, and the blade 322 extends to the outer end face 33. The outer end face 33 of the knife head 32 can contact the base at the root of the pin during operation, and the blade 322 extends to the outer end face 33. When stripping paint, the paint at the root of the pin can be stripped, and the blade 322 strips the paint on the peripheral surface of the pin along the axial direction of the pin, and cooperates with the limiting structure 21 of the knife seat 1 for the knife rod 2 to achieve radial and axial double precision paint stripping, thereby improving the pin quality of the large magnetic ring inductor pin after paint stripping.

[0028] Furthermore, there are three blade rods 2 and three stripping blade members 3, and each stripping blade member 3 has two blades 322. When stripping the paint of each pin, six blades 322 are working, and the paint stripping speed is faster.

[0029] Preferably, the stripping blade 321 is V-shaped, and the blades 322 are located at both sides of the V-shaped stripping blade opening. The stripping blade 321 gradually shrinks inward from the opening, which can effectively prevent pin jumpers and ensure the smoothness of automatic paint stripping.

[0030] In a preferred embodiment of the present invention, the stripping blade member 3 is integrally formed, and the blade head 32 thereof is formed by bending the free end of the mounting portion 31 toward the center.

[0031] A paint stripping machine using the above-mentioned large magnetic ring inductor enameled wire pin stripping knife 10 includes a loading unit, a paint stripping unit, a burr grinding unit, a material unloading unit and a material transfer unit arranged on a frame 900. The paint stripping unit includes a paint stripping frame 11, and the paint stripping frame 11 is provided with a stripping knife 10 and a stripping knife drive 12 driving the stripping knife 10 to work. The burr grinding unit includes an abrasive bin 4 arranged on the frame 900, and an abrasive component 41 and an abrasive drive 42 are arranged in the abrasive bin 4. A dust cover 43 is arranged on the outer periphery of the abrasive component 41. The material transfer unit includes a material transfer manipulator 5 and a material transfer drive 6 driving the material transfer manipulator 5 to move. The material transfer unit automatically takes the material, clamps the large magnetic ring 100 to the stripping knife 10 for paint stripping, and then transfers the material to the burr grinding unit for automatic burr grinding, and then sends it to the material unloading unit for unloading, so as to realize automatic and precise paint stripping.

[0032] Preferably, the paint stripping frame 11 is provided with at least two sets of stripping knives 10 and stripping knife drives 12, and the paint stripping frame 11 is provided with a first drive 13 for driving the stripping knives 10 and the stripping knife drive 12 to move. Different stripping knives can meet the paint stripping requirements of different wire diameters, improve the stripping automation efficiency and the universal adaptability of the paint stripping machine.

[0033] In order to collect the paint residue after paint stripping in time, a waste hopper 14 is provided below the paint stripping end of the stripping knife 10 to collect the paint residue and prevent the machine and environment from being polluted. The waste hopper 14 can be arranged on the paint stripping frame 11 or on the frame 900.

[0034] In order to grind burrs better without damaging the large magnetic ring 100, an alignment plate 40 is provided on the abrasive bin 4. The alignment plate 40 is provided with pin holes 401 corresponding to the inductor pins and a clearance clamping hole 402. The abrasive bin 4 is provided with a second drive 44 for driving the abrasive member 41 and its abrasive drive 42 to move. The abrasive drive 42 includes a telescopic drive for driving the abrasive member 41 to extend and retract and a rotation drive for driving the abrasive member 41 to rotate. The second drive 44 is a translation drive.

[0035] Preferably, the material transfer drive 6 is a two-dimensional moving drive, and the material transfer robot 5 has two clamping parts 51 that can be opened and closed. The material transfer robot 5 can rotate to keep the clamped large magnetic ring 100 horizontally clamped, and then rotate to make the pins of the large magnetic ring 100 face the stripping knife 10. This is more conducive to the layout of each working unit of the entire automatic paint stripping machine.

[0036] When grinding burrs, the clamping piece 51 of the material transfer robot 5 clamps the large magnetic ring 100 to the alignment plate 40. When the clamping piece 51 aligns to make way for the clamping hole 402, the pin of the large magnetic ring 100 passes through the pin hole 401, and the second drive 44 moves the abrasive piece 41 and the abrasive drive 42 to the pin hole 401. The telescopic drive makes the abrasive piece 41 rise and contact with the pin, and then the rotation drive makes the abrasive piece 41 rotate to grind the burrs on the pin wire end.

[0037] Preferably, the end surface of the abrasive piece 41 is a plane or an annular surface, which can be opposite to all the pins at one time, and the burrs on the end surfaces of all the pins can be quickly and accurately ground off.

[0038] The dust cover 43 prevents the burrs from flying around the abrasive piece 41. In order to discharge the burrs and dust in time, the dust cover 43 is preferably provided with a dust exhaust channel 431 connected to its inner cavity. Furthermore, a negative pressure device can be connected to the outlet of the dust exhaust channel 431 to quickly discharge the dust.

[0039] In one embodiment of the present invention, the loading unit and the unloading unit respectively include a loading platform 7 and a second drive 8 for driving the loading platform 7 to move. The second drive 8 can be a rotation drive or a combination of rotation and translation drive, which is convenient for receiving and feeding materials from the previous process to the next process. Specifically, the loading unit is close to the paint stripping unit, and the unloading unit is close to the burr grinding unit, and the layout is reasonable. Of course, the positioning and detection mechanisms are set in the loading unit and the unloading unit to improve automation.

[0040] When the paint stripping machine of the present invention is working, the large magnetic ring 100 is sent to the loading platform 7 of the loading unit by the previous process, the control system is started, the manipulator 5 is driven by the material transfer drive 6 to move to the loading unit to pick up the material, and send it to the paint stripping unit, the large magnetic ring 100 is flipped so that its pin is opposite to the stripping knife 10, and then the stripping knife 10 is driven to move to the pin, and the stripping knife 10 is driven to work to strip the paint. After one pin is stripped, the large magnetic ring 100 is moved so that all the pins are stripped in turn, the material transfer manipulator 5 moves the large magnetic ring 100 again and flips it so that its pin points to the alignment plate 40 on the grinding bin 4, and after the pin of the large magnetic ring 100 is inserted into the pin hole 401, the burr grinding unit works to grind off the burrs on the end face of the pin, and then the large magnetic ring 100 is transferred to the loading platform 7 of the unloading unit, and the paint stripping of a large magnetic ring is completed.
