Description

Technical Field

[0001] This invention relates to the field of electromagnetic coil terminal paint removal technology, and in particular to a fully automatic electromagnetic coil terminal paint removal machine and method. Background Technology

[0002] An electromagnetic coil is an electrical conductor, such as a wire, in the shape of a coil, helix, or spiral. Electromagnetic coils are used in electrical engineering, where current interacts with a magnetic field, in applications such as electric motors, generators, inductors, electromagnets, transformers, and sensor coils. Current flowing through the coil's wires generates a magnetic field, or conversely, an external time-varying magnetic field passing through the coil's interior induces a voltage in the conductor. Electromagnetic coils often have two symmetrically arranged terminals for easy connection.

[0003] Currently, the process of removing the paint from electromagnetic coil terminals often relies on manual operation, resulting in low paint removal efficiency, unstable paint removal quality, and high production costs. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a fully automatic electromagnetic coil terminal paint stripping machine and method.

The first connecting rod and the second connecting rod are rotatably connected to the side walls of two magnetic blocks, respectively. A first housing is fixedly connected to the other end of the first rotating shaft. A slider is elastically connected to the inner walls of both the first housing and the second housing via conductive springs. An electric push rod is fixedly connected to the bottom wall of both sliders. A polishing machine is fixedly connected to the movable end of one of the electric push rods, and a brush roller is fixedly connected to the movable end of the other electric push rod.

[0007] Furthermore, the inner wall of the brush roller is provided with multiple coating tubes, the bottom side wall of the brush roller is provided with an annular groove, the inner wall of the annular groove is fixedly connected with an annular airbag, the side wall of the annular airbag is fixedly connected with multiple receiving boxes, the inner wall of the slider fixedly connected to the polishing machine is fixedly connected with a support frame, the bottom wall of the support frame is fixedly connected with multiple air jets, and the inner side wall of the bottom frame is fixedly connected with multiple air jet pipes.

[0008] Furthermore, the inner wall of the top plate is provided with a cavity, a first sliding cavity, and a second sliding cavity. A first magnetic plug and a second magnetic plug are slidably connected in a sealed manner in the cavity. A first magnetic ring and a second magnetic ring are slidably connected in a sealed manner in the first sliding cavity. A first tube, a second tube, and a third tube are fixedly connected through the inner wall of the cavity. The first tube is fixedly connected to the coating tube, the second tube is fixedly connected to the jet head, and the third tube is fixedly connected to the jet pipe. A cooling chip is fixedly connected to the inner wall of the cavity. A one-way valve is provided in each of the first, second, and third tubes.

[0009] Furthermore, a servo motor is fixedly connected to the inner wall of the bottom of the base frame, and a mounting plate is fixedly connected to the output end of the servo motor.

[0010] Furthermore, clamping plates are symmetrically fixedly connected to the top wall of the mounting plate, and clamping airbags are fixedly connected to the inner wall of the clamping plates. The clamping airbags are fixedly connected to the inner walls of both ends of the first sliding cavity through air inlet pipes.

[0011] Furthermore, an exhaust pipe is fixedly connected through the inner wall of the annular airbag, and an open safety valve is provided inside the exhaust pipe. The annular airbag is fixedly connected to the inner wall of the second sliding cavity through a connecting pipe, and a one-way valve is provided inside the connecting pipe.

[0012] Furthermore, the two sliders are slidably connected to the inner walls of the first and second boxes, respectively, and the conductive spring is electrically connected to an external power source through a sliding rheostat.

[0013] A fully automatic method for stripping the coating from electromagnetic coil terminals as described in any one of claims 1 to 7 includes the following steps:

[0014] S1. Place the electromagnetic coil on the upper part of the mounting plate, with both terminals of the electromagnetic coil facing upwards;

[0015] S2. Turn on the motor so that the brush roller brushes and removes paint from one of the terminals. Control the height of the grinder and brush roller with the electric push rod. Then turn on the servo motor so that the electromagnetic coil rotates 180 degrees. Turn on the grinder and the grinding rod part of the grinder abuts against the side wall of one terminal to grind. The brush roller brushes and removes paint from the other terminal.

[0016] S3. Turn on the servo motor again to allow the grinder to grind and remove paint from the other terminal.

[0017] The present invention has the following advantages:

[0018] 1. By setting up multiple connecting rods, rotating rods, and sliders, and by inputting different currents to the conductive springs, the movement trajectories of the grinding rod and the brush roller of the grinder are both circular. In this way, the grinding rod of the grinder can be closely attached to the side wall of the cylindrical terminal for grinding, and the bristles on the side wall of the brush roller brush against the side wall of the cylindrical terminal. Furthermore, the diameter of the circular trajectory can be adjusted, increasing the applicability of this device.

[0019] 2. By setting up multiple magnetic blocks, multiple magnetic plugs and coating tubes, when the first magnetic plug and the second magnetic plug slide backwards to seal on both sides, the first magnetic plug squeezes the paint remover in the left part of the cavity into the coating tube for outflow. Then the paint remover is applied to the bristles of the brush roller, and the bristles continuously brush one of the terminal side walls. Under the action of the paint remover, a chemical reaction occurs on the terminal side wall, and the paint is removed.

[0020] 3. Simultaneously, as the first magnetic plug slides to the right to seal and gradually approaches the second magnetic plug, the gas in the cavity will be squeezed to the jet nozzle and ejected, thereby blowing away the dust generated by the grinding rod part of the grinder during the grinding process; when the first and second magnetic plugs slide to the right to seal synchronously, the second magnetic plug squeezes the cold air inside the cavity, which has been cooled by the cooling plate, to the jet nozzle and ejects it, thereby dissipating heat and cooling the grinder and preventing abnormal high temperature from occurring during long-term continuous operation of the grinder.

[0021] 4. During the movement of the first magnetic plug, the first magnetic ring and the second magnetic ring will move synchronously, so that the first magnetic ring will continuously squeeze the gas in the first sliding cavity into the clamping air bag, and the clamping air bag will elongate in the horizontal direction, thereby clamping the electromagnetic coil.

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Reference Figure 1-6An automatic electromagnetic coil terminal paint stripping machine includes a base frame 1 and an electromagnetic coil 36.

[0031] The inner wall of the brush roller 19 is provided with multiple coating tubes 31. The bottom side wall of the brush roller 19 is provided with an annular groove 32. An annular airbag 33 is fixedly connected to the inner wall of the annular groove 32. Multiple receiving boxes 34 are fixedly connected to the side wall of the annular airbag 33. The inner wall of the slider 17, which is fixedly connected to the sander 18, is fixedly connected with a support frame 28. Multiple air nozzles 29 are fixedly connected to the bottom wall of the support frame 28. Multiple air pipes 35 are fixedly connected to the inner side wall of the bottom frame 1. After the annular airbag 33 is inflated, it only expands outward, thereby driving the multiple receiving boxes 34 to collect the small amount of paint remover left on the side wall of the brush roller 19. The bottom side wall of the brush roller 19 is provided with a guide groove, so that the paint remover sliding down the side wall of the brush roller 19 flows into the multiple receiving boxes 34 for collection, avoiding the paint remover from affecting the electromagnetic coil 36.

[0032] The inner wall of the top plate 3 has a cavity 42, a first sliding cavity 21, and a second sliding cavity 27. A first magnetic plug 22 and a second magnetic plug 23 are slidably connected within the cavity 42. A first magnetic ring 43 and a second magnetic ring 44 are slidably connected within the first sliding cavity 21. A first tube 24, a second tube 25, and a third tube 26 are fixedly connected through the inner wall of the cavity 42. The first tube 24 is fixedly connected to the coating tube 31, the second tube 25 is fixedly connected to the jet nozzle 29, and the third tube 26 is fixedly connected to the jet pipe 35. A cooling chip 46 is fixedly connected to the inner wall of the cavity 42. One-way valves are provided in the first tube 24, the second tube 25, and the third tube 26. The one-way valve in the first tube 24 only allows the paint remover in the cavity 42 to flow out from the coating tube 31, while the one-way valve in the second tube 25... The one-way valve only allows the gas in cavity 42 to be ejected from the jet head 29. The one-way valve in the third tube only allows the cold air in cavity 42 to be ejected from the jet pipe 35. The first magnetic plug 22 and the second magnetic plug 23 divide cavity 42 into three parts: left, middle and right. The first tube 24 is located in the left part of cavity 42, the second tube 25 is located in the middle part of cavity 42, and the third tube 26 is located in the right part of cavity 42. The cooling chip 46 is located in the right part of cavity 42. The inner walls of the left, middle and right parts of cavity 42 are all fixedly connected with one-way inlet pipes. The one-way inlet pipe in the left part of cavity 42 is fixedly connected to the paint remover box in the outside. The left part of cavity 42 is filled with paint remover. The one-way inlet pipes in the middle and right parts of cavity 42 only allow the outside gas to enter the interior of cavity 42.

[0033] A servo motor 41 is fixedly connected to the inner wall of the bottom of the base frame 1. A mounting plate 40 is fixedly connected to the output end of the servo motor 41. The servo motor 41 rotates 180 degrees in a single rotation. Then, the two terminals 37 of the electromagnetic coil 36 are swapped 180 degrees through the mounting plate 40.

[0034] A clamping plate 38 is symmetrically fixedly connected to the top wall of the mounting plate 40. A clamping airbag 39 is fixedly connected to the inner wall of the clamping plate 38. The clamping airbag 39 is fixedly connected to the inner walls of both ends of the first sliding cavity 21 through an air inlet pipe. A one-way air inlet pipe is symmetrically opened on the inner wall of the first sliding cavity 21. A pressure relief pipe is provided on the inner wall of the clamping airbag 39. A pressure relief valve is provided in the pressure relief pipe. When the pressure inside the clamping airbag 39 is too high, some gas will be discharged from the clamping airbag 39 to ensure that the air pressure inside the clamping airbag 39 is stable.

[0035] An exhaust pipe is fixedly connected to the inner wall of the annular airbag 33. An open safety valve is installed in the exhaust pipe. The annular airbag 33 is fixedly connected to the inner wall of the second sliding cavity 27 through a connecting pipe. A one-way valve is installed in the connecting pipe. The one-way valve in the connecting pipe only allows gas in the second sliding cavity 27 to enter the annular airbag 33. A one-way air supply hole is opened in the inner wall of the second sliding cavity 27. When the air pressure inside the annular airbag 33 reaches a certain value, the open safety valve in the exhaust pipe will open quickly, so that the gas inside the annular airbag 33 will be discharged quickly. The annular airbag 33 will contract, driving the receiving box 34 to retract, so as to prevent the exposed receiving box 34 and the terminal 37 from contacting each other.

[0036] Two sliders 17 are slidably connected to the inner walls of the first box 15 and the second box 16 respectively. The conductive spring 45 is electrically connected to the external power supply through a sliding rheostat, and the current flowing through the conductive spring 45 is controlled by the sliding rheostat.

[0037] A fully automatic method for stripping the coating from electromagnetic coil terminals according to any one of the above-mentioned methods includes the following steps:

[0038] S1. Place the electromagnetic coil 36 on the upper part of the mounting plate 40, and place the two terminals 37 of the electromagnetic coil 36 facing upwards;

[0039] S2. Turn on motor 7 so that brush roller 19 brushes and removes paint from one of the terminals 37. The height of grinder 18 and brush roller 19 is controlled by electric push rod 20. Then turn on servo motor 41 so that electromagnetic coil 36 rotates 180 degrees and grinds grinder 18. The grinding rod part of grinder 18 grinds against the side wall of one terminal 37, and brush roller 19 brushes and removes paint from the other terminal 37.

[0040] S3. Turn on the servo motor 41 again so that the grinder 18 can grind and remove paint from the other terminal 37.

[0041] In this invention, an arc-shaped groove is provided in the mounting plate 40. The electromagnetic coil 36 is placed in the arc-shaped groove. When the motor 7 is turned on, the output end of the motor 7 drives the first rotating rod 8 to rotate, and then the first rotating rod 8 drives the second rotating rod 9 to rotate synchronously. The second rotating rod 9 drives the first connecting rod 11 and the second connecting rod 12 to move through the first rotating shaft. Since the first connecting rod 11 and the second connecting rod 12 are respectively rotatably connected to the side walls of the two magnetic blocks 5, and the side walls of the two magnetic blocks 5 are respectively rotatably connected to the third connecting rod 13 and the fourth connecting rod 14, with one end of the third connecting rod 13 and the fourth connecting rod 14 rotatably connected, the first connecting rod 11... Link 11, second link 12, third link 13, and fourth link 14 form a parallelogram structure. As the second rotating rod 9 rotates, the two magnetic blocks 5 will also move with the second rotating rod 9. The repeated sliding path of the two magnetic blocks 5 is as follows: when the first link 11 and the second link 12 are squeezed and move to the sides respectively, the two magnetic blocks 5 slide in opposite directions, and then slide to the left synchronously for a distance. Then the magnetic block 5 on the left side slides to the right quickly for a distance, but will not contact the magnetic block 5 on the right side. Finally, the two magnetic blocks 5 slide to the right synchronously for a distance, and the above process is repeated continuously.

[0042] The first housing 15 and the second housing 16 are both arranged parallel to the second rotating rod 9. Under the action of the first and second rotating shafts, different currents are passed through the sliding rheostat to the two conductive springs 45, which in turn cause the conductive springs 45 to contract to different degrees. This causes the two sliders 17 to jointly drive the corresponding grinder 18 and brush roller 19 to slide the same distance. Then, under the action of multiple connecting rods and magnetic blocks 5, the movement trajectory of the grinding rod part of the grinder 18 and the brush roller 19 is a circular trajectory. The grinding rod part of the grinder 18 can be closely attached to the side wall of the cylindrical terminal 37 for grinding, and the bristles on the side wall of the brush roller 19 brush against the side wall of the cylindrical terminal 37. The diameter of the circular trajectory can be adjusted to increase the applicability of this device.

[0043] During the sliding process of the two magnetic blocks 5, the side wall of one magnetic block 5 and the side wall of the first magnetic plug 22 are facing each other, and their polarities are opposite and they are magnetically attracted to each other. The side wall of the other magnetic block 5 and the side wall of the second magnetic plug 23 are facing each other, and their polarities are opposite and they are magnetically attracted to each other. There is no interference between the first magnetic plug 22 and the second magnetic plug 23. Then the two magnetic blocks 5 will drive the corresponding magnetic plugs to move synchronously.

[0044] When the first magnetic plug 22 and the second magnetic plug 23 slide to seal and slide to both sides respectively, the first magnetic plug 22 squeezes the paint remover in the left part of the cavity 42 into the coating tube 31 for flow out. Then the paint remover is applied to the brush bristles of the brush roller 19. The brush bristles continuously brush the side wall of one of the terminals 37. Under the action of the paint remover, a chemical reaction occurs on the side wall of the terminal 37, and the paint is removed.

[0045] Simultaneously, as the first magnetic plug 22 slides to the right to seal and gradually approaches the second magnetic plug 23, paint remover is drawn into the left side of the cavity 42, and the gas in the middle of the cavity 42 is squeezed to the jet nozzle 29 and ejected, thereby blowing away the dust generated by the grinding rod part of the grinder 18 during the grinding process; when the first magnetic plug 22 and the second magnetic plug 23 slide to the right to seal simultaneously, the second magnetic plug 23 squeezes the cold air inside the cavity 42, which has been cooled by the cooling plate 46, to the jet pipe 35 and ejects it. The jet pipe 35 is directly facing the grinder 18, thereby dissipating heat and cooling the grinder 18, and preventing the grinder 18 from generating abnormal high temperature during long-term continuous operation.

[0046] Since the first magnetic plug 22 and the first magnetic ring 43 and the second magnetic ring 44 have opposite polarities and attract each other magnetically, and the first magnetic ring 43 and the second magnetic ring 44 are far away from the magnetic block 5, the first magnetic plug 22 will drive the first magnetic ring 43 and the second magnetic ring 44 to move synchronously during its movement. This causes the first magnetic ring 43 to continuously squeeze the gas in the first sliding cavity 21 into the clamping airbag 39, causing the clamping airbag 39 to elongate in the horizontal direction, thereby clamping the electromagnetic coil 36.

[0047] Simultaneously, the second magnetic ring 44 compresses the gas in the second sliding cavity 27 into the annular airbag 33. After the annular airbag 33 is inflated, it only expands outward, thereby driving multiple receiving boxes 34 to collect the small amount of paint remover left on the side wall of the brush roller 19. The bottom side wall of the brush roller 19 is provided with a guide groove, so that the paint remover sliding down the side wall of the brush roller 19 flows into the multiple receiving boxes 34 for collection, avoiding the paint remover from affecting the electromagnetic coil 36. The open safety valve in the exhaust pipe inside the annular airbag 33 will quickly open after the air pressure inside the annular airbag 33 reaches a certain value, so that the gas inside the annular airbag 33 is quickly discharged. The annular airbag 33 contracts, driving the receiving box 34 to retract, avoiding the exposed receiving box 34 and terminal 37 from coming into contact with each other when the paint remover is applied, thus preventing poor contact between the brush bristles and terminal 37.

[0048] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
