Description

Technical Field

[0001] This invention relates to the field of magnetization, and more particularly to an automatic magnetization device and method for headphone cases. Background Technology

[0002] In daily life, over-ear headphones are widely used, and some are quite expensive. Therefore, many manufacturers have designed protective cases to store the headphones when not in use. These cases often use magnetic attachments at the connection points. To ensure stability, multiple connection points are needed, and each point is paired, requiring multiple magnets. During case production, for ease of manufacturing, non-magnetic magnets are often initially attached to the case. If the magnets become magnetic during production, they can attract the production equipment or other metals, hindering production. After attaching the non-magnetic magnets, they are then magnetized. However, current magnetizing machines magnetize each magnet individually, which is inefficient. Summary of the Invention

[0039] like Figure 1-3 As shown, the headphone case 100 includes a first part 101, two second parts 102, and two third parts 103. In the unfolded state, one end of each of the two second parts 102 is connected to one end of the first part 101. The first part 101 and the two second parts 102 form a herringbone structure. One side of the case 100 is smooth, and the other side is textured. In use, the textured side contacts the headphones. Two first magnets 104 are provided on the end of the first part 101 away from the second parts 102. A second magnet 105 is provided on each second part 102 near its free end, and two third magnets 106 are also provided on each second part 102 near its free end. In use, the second magnets 105 attract the corresponding first magnets 104, and the third magnets 106 attract the parts of the headphones that are in contact with each other.

[0040] One end of the third part 103 is connected to the end of the corresponding second part 102 that is close to the first part 101. A notch 1031 is provided on one third part 103, and a protrusion 1032 is provided on the end of the other third part 103 that is away from the second part 102.

[0041] like Figure 4-8As shown, an automatic magnetizing device for a headset case includes a frame 1, a first mounting plate 2 mounted on the frame 1, a second mounting plate 3 mounted on the first mounting plate 2, and a first magnetizing assembly mounted on the second mounting plate 3. The first magnetizing assembly is used to magnetize a second magnet 105 and a third magnet 106. The first magnetizing assembly includes a first mounting base 55, two first magnetizing coils 51, and four second magnetizing coils 52. First mounting slots 551 are provided on the left and right sides of the first mounting base 55. Each first mounting slot 551 contains one first magnetizing coil 51 and two second magnetizing coils 52. A first connecting slot 552 is provided between two first mounting slots 551 to connect the two first mounting slots 551 and to place wires connected to the first magnetizing coils 51 and the second magnetizing coils 52. A first support plate 41 is provided on the second mounting plate 3 and located behind the first mounting base 55. A positioning plate 42 is provided on the first mounting base 55 and the first support plate 41. A first positioning groove 43 is formed on the positioning plate 42, and the shape of the first positioning groove 43 is consistent with the shape of the leather sleeve 100. When the leather sleeve 100 is placed in the first positioning groove 43, the second magnet 105 corresponds to the corresponding first magnetizing coil 51, and the third magnet 106 corresponds to the corresponding second magnetizing coil 52.

[0042] Preferably, a second support plate 44 is provided on the first mounting plate 2 and located in front of the second mounting plate 3. The second support plate 44 is located in the middle of the first mounting plate 2 in the left-right direction. Two second positioning grooves 441 for positioning the end of the third part 103 are formed on the second support plate 44. The size of the second support plate 44 in the left-right direction is smaller than the size of the first mounting base 55, which can save materials and space.

[0043] A third mounting plate 6 is also provided directly above the first mounting base 55 and the first support plate 41. The third mounting plate 6 is movable vertically. A second magnetizing assembly is provided on the lower surface of the third mounting plate 6. The second magnetizing assembly includes a second mounting seat 56 disposed on the lower surface of the third mounting plate 6.

The fourth magnetizing coils 54 are aligned vertically with the second magnetizing coils 52. By simultaneously magnetizing the third magnet 106 with the second magnetizing coils 52 and the fourth magnetizing coils 54, the third magnet 106 can have a stronger magnetism to meet the magnetic force requirements. The second connecting slot 562 is used to place the wires connected to the fourth magnetizing coils 54.

[0044] The second magnetizing assembly also includes a third mounting base 57 disposed on the lower surface of the third mounting plate 6 and located behind the second mounting base 56. The third mounting base 57 is provided with a third mounting groove 571 with its opening facing downward. Two third magnetizing coils 53 are disposed in the third mounting groove 571. When the leather sleeve 100 is placed in the first positioning groove 43, the two third magnetizing coils 53 correspond to the two first magnets 104 respectively and are used to magnetize the first magnets 104.

[0045] A pressure plate 7 is provided on the third mounting plate 6 and located behind the second mounting base 56. The lower surface of the pressure plate 7 is on the same plane as the lower surfaces of the second mounting base 56 and the third mounting base 57. When viewed from above, the pressure plate 7 is U-shaped, with the opening of the U-shape facing away from the second mounting base 56. The third mounting base 57 is located inside the opening of the U-shape.

[0046] When magnetization is required, the leather sleeve 100 is placed in the first positioning groove 43 and the second positioning groove 441. Then, the third mounting plate 6 moves downward so that the pressure plate 7 contacts the positioning plate 42, and the magnetization controller is activated to control each magnetization coil to magnetize the corresponding magnet. After magnetization is completed, the third mounting plate 6 moves upward a certain distance to remove the magnetized leather sleeve 100, thus completing the magnetization.

[0047] The principle of each coil magnetizing the magnet uses existing technology.

[0048] Furthermore, a fourth mounting plate 8 is provided above the third mounting plate 6. The fourth mounting plate 8 is supported on the second mounting plate 3 by a plurality of support rods 81. The third mounting plate 6 is slidably mounted on the support rods 81. A drive cylinder 82 is provided on the fourth mounting plate 8. The cylinder body of the drive cylinder 82 is fixed on the fourth mounting plate 8. The free end of the cylinder rod of the drive cylinder 82 extends downward and is connected to the third mounting plate 6. The vertical extension and retraction of the cylinder rod of the drive cylinder 82 can drive the pressure plate 7 to move up and down.

[0049] An outer cover 9 is provided on the first mounting plate 2, which is covered by the second mounting plate 3, the first magnetizing component, the third mounting plate 6, the second magnetizing component, the fourth mounting plate 8, and the support rod 81. A portion of the drive cylinder 82 passes through the top of the outer cover 9. The outer cover 9 has only an opening on the front side, through which workers can easily put in or take out the leather case.

[0050] Furthermore, two switch buttons 10 are provided on the first mounting plate 2. These two switch buttons 10 are used to start the magnetization controller, and both switch buttons 10 must be pressed simultaneously to start the device. This ensures that the operator's hand can be removed from between the two magnetization components during startup. Meanwhile, sensors 101 are provided on the left and right sides of the front opening of the outer cover 9 to detect whether there are any objects, especially human hands, placed in the opening. When an object is detected, the device cannot start, thus providing a protective function.
