Description

Technical Field

[0001] This invention relates to the field of enameled aluminum wire production technology, and in particular to a pretreatment device for high-quality aluminum electromagnetic wire. Background Technology

[0002] Enameled flat wire, as an important type of aluminum electromagnetic wire, is widely used in new energy vehicle drive motors, large power transformers, industrial motors, and special electromagnetic devices. Compared with round wire, flat wire has advantages such as high space utilization, good heat dissipation, and high power density. Enameling insulation is the core process in the manufacturing of enameled flat wire, and its quality directly determines the insulation strength, heat resistance, and reliability of this type of aluminum electromagnetic wire. In existing technologies, the inner core of the flat wire is usually an aluminum strip, and enameling is performed on the outside of the aluminum strip. Before enameling, the surface of the aluminum strip needs to be cleaned to avoid burrs affecting the final coating effect. Existing technologies typically add a burr-removing process before enameling to trim the aluminum strip before enameling. However, existing burr-removing processes lack an inspection process after burr removal, making the effectiveness of burr removal uncertain and potentially affecting the enameling effect. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a high-quality aluminum electromagnetic wire pretreatment device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A high-quality aluminum electromagnetic wire pretreatment device includes a base plate, a conveying roller mounted on the base plate for conveying aluminum strips, a burr grinding device on the base plate for grinding the burrs at the edges of the aluminum strips, and a detection device for the burr grinding results on both sides of the aluminum strips.

[0005] Preferably, two upright plates are fixedly connected to the base plate, and a crossbeam is fixedly connected between the two upright plates. A slider is slidably connected to the crossbeam, and a first hydraulic cylinder is mounted on the slider. The telescopic end of the first hydraulic cylinder is equipped with a conveying device, which is used to drive the aluminum strip to slide along the conveying roller.

[0006] Preferably, the conveying device includes an assembly frame, on which multiple rotating shafts are rotatably connected, and a motor is mounted on the assembly frame. The main shaft of the motor drives all the rotating shafts to rotate simultaneously through a transmission assembly.

[0007] Preferably, the upright plate is equipped with two guiding devices, which are symmetrically arranged around the aluminum strip. Each guiding device includes a second hydraulic cylinder, and the telescopic end of the second hydraulic cylinder is equipped with a guide roller. A guiding channel is formed between the guide rollers of the two guiding devices.

[0008] Preferably, there are two detection devices, which are symmetrically arranged around the aluminum strip. Each detection device includes a mounting plate, a sliding rod slidably connected to one side of the mounting plate, and two mounting posts at one end of the sliding rod. The angle between the two mounting posts is 30°-90°. Each mounting post has a mounting groove on one side, and each mounting groove contains a balloon. An inflation device is installed on one side of the mounting plate.

[0009] Preferably, the inflation device includes a third hydraulic cylinder, the telescopic end of which is fixedly connected to an inflation tank, and an inflation needle is provided on one side of the inflation tank.

[0010] Preferably, the detection device is provided with swing devices on both the upper and lower sides. The swing devices include a rotating roller with a pull rope wound around it, and one end of the pull rope is connected to the mounting column.

[0011] The beneficial effects of this invention are: the burr removal device trims the edges of aluminum strips before enameling, preventing burrs on the aluminum strips from affecting the subsequent enameling process. At the same time, this invention is suitable for aluminum strips of different widths and thicknesses. In addition, the detection device can check the polishing results of the polished aluminum strips to ensure that the burrs are polished clean. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0019] like Figures 1-6As shown, this embodiment of a high-quality aluminum electromagnetic wire pretreatment device includes a base plate 1, on which two conveying rollers 11 are mounted. The conveying rollers 11 are used to convey aluminum strips 100. Two upright plates 3 are fixedly connected to the base plate 1, and a crossbeam 32 is fixedly connected between the two upright plates 3. The crossbeam 32 is provided with a guide groove 33, and a slider 34 is slidably connected in the guide groove 33. The slider 34 has a self-locking function, that is, after moving to a designated position, it locks itself in the guide groove 33. A first hydraulic cylinder 35 is mounted on the slider 34, and a conveying device 4 is mounted on the telescopic end of the first hydraulic cylinder 35. The conveying device 4 is used to drive the aluminum strips 100 to slide along the conveying rollers 11. The conveying device 4 includes an assembly frame 41, which is fixed to the telescopic end of the first hydraulic cylinder 35. Multiple rotating shafts 42 are rotatably connected to the assembly frame 41, and a motor 44 is mounted on the assembly frame 41. The main shaft of the motor 44 drives all the rotating shafts 42 to rotate simultaneously through a transmission assembly. The transmission assembly adopts a chain and sprocket structure, which is existing technology and will not be described in detail here. During the conveying process, the position of the conveying device 4 is adjusted by changing the position of the slider 34. The first hydraulic cylinder 35 pushes the conveying device 4 downward, so that the rotating shaft 42 presses the aluminum strip 100. Then, the motor 44 drives the rotating shaft 42 to rotate, and under the action of friction, the aluminum strip 100 moves forward along the conveying roller 11.

[0020] To accommodate aluminum strips 100 of varying widths, a through groove 31 is provided on the upright plate 3. The aluminum strip 100 passes through the through groove 31. Two guiding devices are mounted on the upright plate 3, located on opposite sides of the through groove 31 and symmetrically arranged with the aluminum strip 100 as the center. Each guiding device includes a second hydraulic cylinder 51, with a guide roller 5 mounted on its telescopic end. A guiding channel is formed between the guide rollers 5 of the two guiding devices. The second hydraulic cylinder 51 moves the guide rollers 5, changing their position and thus the size of the guiding channel. The guiding channel guides the forward direction of the aluminum strip 100. The guide rollers 5 are existing technology and will not be described further here.

[0021] The base plate 1 is equipped with a burr grinding device 2, which is located between the two conveying rollers 11. The burr grinding device 2 is used to grind the burrs at the edges of the aluminum strip 100 clean. The burr grinding device 2 is existing technology, and how it removes burrs is also existing technology, which will not be described in detail here.

[0022] On both sides of the aluminum strip 100, there are also detection devices 6 for the results of burr grinding. After the burr grinding device 2 grinds the burr, the detection device 6 can detect the results of the burr grinding, thereby improving the reliability of the finishing of the aluminum strip before enameling.

[0023] Two detection devices 6 are arranged symmetrically around the aluminum strip 100. Each detection device 6 includes a mounting plate 61, with a sliding rod 62 slidably connected to one side of the mounting plate 61. Two mounting posts 63 are mounted on one end of the sliding rod 62, with an angle between the two mounting posts 63 ranging from 30° to 90°, preferably 45° in this embodiment. Each mounting post 63 has a mounting groove on one side, and each mounting groove contains a balloon 64. During use, the balloon 64 comes into contact with the edges of the aluminum strip 100. If there are burrs on the edges of the aluminum strip 100 that have not been properly polished, the contact between the burrs and the balloon 64 will cause the balloon 64 to burst.

[0024] To facilitate control of the air pressure of balloon 64, an inflation device is installed on one side of the mounting plate 61. The inflation device includes a third hydraulic cylinder 68, the telescopic end of which is fixedly connected to an inflation tank 69. An inflation needle 610 is provided on one side of the inflation tank 69. The inflation needle 610 corresponds to the inflation hole 67 of balloon 64. By pushing the inflation tank 69 horizontally through the third hydraulic cylinder 68, the inflation needle 610 can be inserted into the inflation hole 67 for inflation.

[0025] The detection device 6 is equipped with swing devices on both its upper and lower sides. Each swing device includes a rotating roller 65 with a pull rope 66 wound around it. One end of the pull rope 66 is connected to the mounting post 63. The continuous reciprocating rotation of the two rotating rollers 65 causes the mounting post 63 and the balloon 64 to swing, resulting in different displacements of the balloon 64 and the edges of the aluminum strip 100. This allows the balloon 64 to make more thorough contact with the edges of the aluminum strip 100, further improving the inspection effect on the burr removal results.
