DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Reference Figure 1-2 A device for removing spots on the surface of an enameled wire includes a workbench 1 and a frame 12 installed on the upper part of the workbench 1. A first liquid tank 2 and a second liquid tank 3 are respectively provided on the upper part of the workbench 1 from left to right. The second liquid tank 3 is separated from the first liquid tank 2 by a partition 4. A bubble generator body 8 is installed in the first liquid tank 2. A control box 9 is installed on the side wall of the workbench 1, and the control box 9 is electrically connected to the bubble generator body 8.

[0028] In the prior art, spots on the outer surface of the enameled wire are treated by applying chemical reagents or rubbing, but this method may cause damage to the substrate.

[0029] To this end, a first liquid tank 2 and a second liquid tank 3 are set on the upper part of the workbench 1. The interior of the first liquid tank 2 is filled with a cleaning liquid and a filler consisting of silicon carbide particles 5 and magnet balls 6. The interior of the second liquid tank 3 is filled with ionized water. A plurality of guide rods 7 are set inside the first liquid tank 2 and the second liquid tank 3. The enameled wire passes through the bottom of the plurality of guide rods 7. At this time, the bubble generator body 8, under the control of the control box 9, continuously transports bubbles to the interior of the first liquid tank 2. When the bubbles burst during the upward process, the burst bubbles generate energy, which will peel off a part of the spots on the outer surface of the enameled wire and at the same time drive the silicon carbide particles 5 to move in the cleaning liquid. During the activity, they come into contact and collide with the spots on the outside of the enameled wire. In this way, the outer surface of the enameled wire is treated.

[0030] Reference Figure 7 A filler is also placed at the bottom of the first liquid tank 2, and the enameled wire contacts the filler during transportation. The filler includes silicon carbide particles 5 and magnet balls 6. The outer surface of the magnet ball 6 is provided with a plurality of holes 21. The diameter of the silicon carbide particles 5 is 60 microns.

[0031] Since some enameled wires will form ferroferric oxide during the painting and baking process, and the ferroferric oxide adheres to the outer surface of the enameled wire, a magnetic ball 6 is added to the first liquid tank 2 to absorb the detached ferroferric oxide particles. The outer surface of the magnetic ball 6 is provided with holes 21, which can absorb and accommodate these ferroferric oxide particles and prevent the free ferroferric oxide particles from returning to the outer surface of the enameled wire.

[0032] A plurality of rotatable guide rods 7 are provided at the inner bottom of each of the first liquid tank 2 and the second liquid tank 3 , and the enameled wire is located at the lower end of the guide rods 7 and contacts the guide rods 7 during transportation.

[0033] When the enameled wire leaves the first liquid tank 2 and enters the inner side of the inclined surface 10 on the partition 4, the round rod 11 is located above the enameled wire at this time, which plays the role of blocking and limiting. The setting of the inclined surface 10 is to peel off the materials that have been cleaned and re-adhered to the enameled wire through contact with the inclined surface 10 during the process of the enameled wire moving forward, and also peel off the cleaning liquid adhered to the surface of the enameled wire. When the enameled wire enters the second liquid tank 3, the interior of the second liquid tank 3 is filled with ionized water, which can further clean the enameled wire.

[0034] refer to Figure 1-2 The partition 4 is conical and the upper part is arc-shaped. An inwardly concave slope 10 is dug in the middle of the partition 4. A plurality of round rods 11 are rotated along the short side direction of the slope 10 on the inner side of the slope 10, and the enameled wire contacts with the round rods 11 when it is conveyed in conjunction with the slope 10.

[0035] refer to Figure 3-6 A fixed rod 13 is provided on the upper part of the frame 12, and a connecting frame 16 is symmetrically installed on the fixed rod 13. An air flow control component 15 is provided between the two connecting frames 16. The air flow control component 15 includes a splint 151, a rotor 152, a slot 153, an air intake pipe 154, a first chamber 155, a circular tube 156 and a second chamber 157. The second chamber 157 is located on the inner side of the splint 151, the first chamber 155 is provided in the rotor 152, and a plurality of slots 153 are distributed in an annular array on the outside of the rotor 152. The rotor 152 is rotatably provided between the two splints 151 through the circular tube 156, and the first chamber 155 and the second chamber 157 are communicated with each other through the circular tube 156. An air intake pipe 154 is provided on one side of the second chamber 157.

[0036] After cleaning, refer to Figure 8As shown, the water is transported vertically upward, accelerating the speed at which water separates from the outer surface of the enameled wire, and contacts the rotor 152 between the two clamping plates 151, driving the rotor 152 to rotate. The rotor 152 plays a guiding role. At the same time, the air flow in the air pump enters the second chamber 157 through the air inlet pipe 154, then enters the first chamber 155 through the circular tube 156, and finally is discharged from the slot 153 on the rotor 152. In this way, the air flow coming out of the slot 153 and the first air outlet 19 below dries the enameled wire. More importantly, during the enameled wire transportation process, when some debris and dust appear between the enameled wire and the rotor 152, the friction will increase. The increased friction will cause wear on the enameled wire, and may form spots on the outer surface of the enameled wire. The air flow overflowing from the slot 153 can remove these impurities and dust. Compared with the external blowing method, the air flow overflowing from the rotor 152 blows away impurities, can accurately process some small particles of fine dust, and is more efficient.

[0037] A protective assembly 14 is provided on the upper part of the frame 12. The protective assembly 14 includes a fixed shaft 141, bristles 142 and a rotating drum 143. The rotating drum rotates in the middle position of the fixed shaft 141. The fixed shaft 141 is installed on the frame 12. The bristles 142 are installed on the outside of the rotating drum 143, and the bristles 142 are in contact with the outer surface of the rotor 152 when rotating.

[0038] An air collecting pipe 17 is provided in the middle position of the fixed rod 13, and a hose 18 is provided on the air collecting pipe 17, and is connected to the air pump through the hose 18. One end of the air inlet pipe 154 is connected to the air collecting pipe 17, and a first air outlet 19 is provided on the upper part of the air collecting pipe 17, and a second air outlet 20 is provided on the side of the air collecting pipe 17. The first air outlet 19 is located directly below the rotor 152, and the second air outlet 20 is directly opposite to the position of the side brush 142.

[0039] A protective assembly 14 consisting of a fixed shaft 141, bristles 142, and a rotating drum 143 is provided obliquely below the rotor 152. The outside of the enameled wire that has just come into contact with the rotor 152 contains some moisture. After this moisture comes into contact with dust, ordinary air blowing can only blow away part of it. Here, it is necessary to use the rotating bristles 142 to deal with these impurities. The bristles 142 cannot be driven by the slowly rotating rotor 152. Therefore, a second air outlet 20 is provided at the side of the air collecting pipe 17. The airflow blown out by the second air outlet 20 can drive the bristles 142 to rotate, and the direction of rotation is opposite to the direction of rotation of the rotor 152. In this way, the bristles 142 can cover the outer surface of the rotor 152 in all directions. Secondly, the airflow blown out by the second air outlet 20 and the first air outlet 19 can not only remove the impurities on the rotor 152, but also blow away the dust adhering to the bristles 142, thereby completing the removal, cleaning, drying and protection of the enameled wire spots.

[0040] The working principle of the device is: In the prior art, spots on the outer surface of the enameled wire are treated by applying chemical reagents or rubbing, but this method may cause damage to the substrate.

[0041] To this end, a first liquid tank 2 and a second liquid tank 3 are set on the upper part of the workbench 1. The interior of the first liquid tank 2 is filled with a cleaning liquid and a filler consisting of silicon carbide particles 5 and magnet balls 6. The interior of the second liquid tank 3 is filled with ionized water. A plurality of guide rods 7 are set inside the first liquid tank 2 and the second liquid tank 3. The enameled wire passes through the bottom of the plurality of guide rods 7. At this time, the bubble generator body 8, under the control of the control box 9, continuously transports bubbles to the interior of the first liquid tank 2. When the bubbles burst during the upward process, the burst bubbles generate energy, which will peel off a part of the spots on the outer surface of the enameled wire and at the same time drive the silicon carbide particles 5 to move in the cleaning liquid. During the activity, they come into contact and collide with the spots on the outside of the enameled wire. In this way, the outer surface of the enameled wire is treated.

[0042] Since some enameled wires will form ferroferric oxide during the painting and baking process, and the ferroferric oxide adheres to the outer surface of the enameled wire, a magnetic ball 6 is added to the first liquid tank 2 to absorb the detached ferroferric oxide particles. The outer surface of the magnetic ball 6 is provided with holes 21, which can absorb and accommodate these ferroferric oxide particles and prevent the free ferroferric oxide particles from returning to the outer surface of the enameled wire.

[0043] When the enameled wire leaves the first liquid tank 2 and enters the inner side of the inclined surface 10 on the partition 4, the round rod 11 is located above the enameled wire at this time, which plays the role of blocking and limiting. The setting of the inclined surface 10 is to peel off the materials that have been cleaned and re-adhered to the enameled wire through contact with the inclined surface 10 during the process of the enameled wire moving forward, and also peel off the cleaning liquid adhered to the surface of the enameled wire. When the enameled wire enters the second liquid tank 3, the interior of the second liquid tank 3 is filled with ionized water, which can further clean the enameled wire.

[0044] After cleaning, refer to Figure 8 As shown, the water is transported vertically upward, accelerating the speed at which water detaches from the outer surface of the enameled wire, and contacts the rotor 152 between the two clamping plates 151, driving the rotor 152 to rotate. The rotor 152 plays a guiding role. At the same time, the air flow in the air pump enters the second chamber 157 through the air inlet pipe 154, and then enters the first chamber 155 through the circular tube 156, and finally is discharged from the slot 153 on the rotor 152. In this way, the air flow coming out of the slot 153 and the first air outlet 19 below dries the enameled wire. More importantly, in the process of conveying the enameled wire, when some debris and dust appear between the enameled wire and the rotor 152, the friction will increase. The increased friction will cause wear on the enameled wire, and spots may form on the outer surface of the enameled wire. The air flow overflowing from the slot 153 can be used to remove these impurities and dust.

[0045] Secondly, a protective assembly 14 consisting of a fixed shaft 141, bristles 142, and a rotating drum 143 is provided obliquely below the rotor 152. The outside of the enameled wire that has just come into contact with the rotor 152 contains some moisture. After this moisture comes into contact with dust, ordinary blowing can only blow away part of it. Here, it is necessary to use the rotating bristles 142 to deal with these impurities, and the bristles 142 cannot be driven by the slowly rotating rotor 152. Therefore, a second air outlet 20 is provided at the side of the air collecting pipe 17. The airflow blown out by the second air outlet 20 can drive the bristles 142 to rotate, and the direction of rotation is opposite to the direction of rotation of the rotor 152, so that the bristles 142 can cover the outer surface of the rotor 152 in all directions. Secondly, the airflow blown out by the second air outlet 20 and the first air outlet 19 can not only remove the impurities on the rotor 152, but also blow away the dust adhering to the bristles 142, thereby completing the removal, cleaning, drying and protection of the enameled wire spots.

[0046] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
