[0015] The present invention will be described in more detail below in conjunction with the accompanying drawings. It should be noted that the description of the present invention with reference to the accompanying drawings is only illustrative and not restrictive. The various embodiments can be combined with each other to form other embodiments not shown in the following description.

[0016] See also Figures 1 to 4 The grinding and gluing device for the magnetic core and the cover plate comprises a first moving part 3, a second moving part 4, a grinding part 5, a cleaning and gluing part 6, and a liquid spraying part 7. The grinding and gluing device is suitable for Figure 4The magnetic core 1 and the cover plate 2 shown in the figure, specifically, the magnetic core 1 includes a first plate 11, a second plate 12, and a winding post 13. The first plate 11 and the second plate 12 are arranged in parallel with each other, and there is at least one winding post 13 between the first plate 11 and the second plate 12, and the two ends of the winding post 13 are respectively fixed to the first plate 11 and the second plate 12. The upper side surface of the cover plate 2 has a first polishing area 21 and a second polishing area 22 arranged at intervals. The first polishing area 21 is arranged in a vertical direction corresponding to the first plate 11, and the second polishing area 22 is arranged in a vertical direction corresponding to the second plate 12. Two protrusions 23 are also protruded between the first polishing area 21 and the second polishing area 22. When the magnetic core 1 is bonded to the cover plate 2, the protrusion 23 is located between the first plate 11 and the second plate 12, and the protrusion 23 can abut against the first plate 11 and the second plate 12. The polishing and gluing device can polish the lower side of the first plate 11 and the second plate 12, and can polish the first polishing area 21 and the second polishing area 22, and can also apply glue to the first polishing area 21 and the second polishing area 22, so as to achieve the bonding of the magnetic core 1 and the cover plate 2.

[0017] The first moving member 3 can move in the horizontal direction and the vertical direction, and a plurality of magnetic cores 1 are fixed on the first moving member 3 in the horizontal direction; the second moving member 4 is located at the lower side of the first moving member 3, the second moving member 4 can move in the horizontal direction and the vertical direction, and a plurality of cover plates 2 are fixed on the second moving member 4 in the horizontal direction; the grinding member 5 is located between the first moving member 3 and the second moving member 4, and the grinding member 5 includes a first grinding plate 51 and a second grinding plate 52 which are arranged at intervals, and the upper side surface of the first grinding plate 51 can abut against the first plate 11, and the first grinding plate 52 can be fixed to the first plate 11. The lower side surface of the grinding plate 51 can abut against the first grinding area 21, the upper side surface of the second grinding plate 52 can abut against the second plate 12, and the lower side surface of the second grinding plate 52 can abut against the second grinding area 22; the air outlet of the cleaning glue-coated part 6 is toward the magnetic core 1 and the cover plate 2, and the glue coating port of the cleaning glue-coated part 6 is toward the first grinding area 21 and the second grinding area 22; wherein, the first movable part 3 and the second movable part 4 are close to each other in the vertical direction, the first plate 11 is bonded to the first grinding area 21, and the second plate 12 is bonded to the second grinding area 22.

[0018] The grinding and gluing device for the magnetic core and the cover plate provided by the present invention fixes the magnetic core 1 to the first movable part 3, and the cover plate 2 to the second movable part 4. Therefore, the magnetic core 1 and the cover plate 2 can be abutted against the grinding part 5 by vertically moving the first movable part 3 and the second movable part 4, and the grinding of the magnetic core 1 and the cover plate 2 can be achieved by horizontally moving the first movable part 3 and the second movable part 4. Thereafter, the gluing part 6 can be cleaned by blowing and gluing, and then the magnetic core 1 and the cover plate 2 can be bonded by vertically moving the first movable part 3 and the second movable part 4, thereby greatly simplifying the process and increasing efficiency.

[0019] It can be imagined that the first movable member 3 and the second movable member 4 can realize horizontal and vertical movement in a variety of ways. For example, the vertical movement can be realized by a combination of a cylinder, an oil cylinder, a motor and a gear, and the horizontal movement can be realized by a combination of a motor and a pulley. This embodiment does not limit the above scheme.

[0020] It is conceivable that during the grinding process of the magnetic core 1, the cover plate 2 and the grinding piece 5, debris will be generated, and the temperature of the magnetic core 1 and the cover plate 2 will be increased. In order to prevent the debris and the excessively high temperature of the magnetic core 1 and the cover plate 2 from affecting the subsequent bonding, it is necessary to clean and cool the magnetic core 1 and the cover plate 2 by cleaning the glue coating piece 6. Specifically, the cleaning glue coating piece 6 may include a shell, and the shell may include a separated first space and a second space. A fan may be provided in the first space, and an air outlet connected to the fan is provided on the upper and lower sides of the shell. The air outlet located on the upper side can blow air to the magnetic core 1, thereby cleaning and cooling the magnetic core 1, and the air outlet located on the lower side can blow air to the cover plate 2, thereby cleaning and cooling the cover plate 2.

[0021] In addition, adhesives, glue coating machines, etc. can be placed in the second space, and a glue coating port can be provided on the lower side of the shell, through which the glue coating machine can spray the adhesive to the first polishing area 21 and the second polishing area 22 .

[0022] It can be imagined that when the first movable member 3 and the second movable member 4 move in the vertical direction, the magnetic core 1 and the cover plate 2 can abut against the polishing member 5, and the pressure between the magnetic core 1, the cover plate 2 and the polishing member 5 directly affects the polishing effect of the magnetic core 1 and the cover plate 2, so it is particularly important to control the pressure between the magnetic core 1, the cover plate 2 and the polishing member 5. In this embodiment, the polishing and gluing device also includes two first pressure sensors and a second pressure sensor. The first pressure sensor can be arranged in the first movable member 3, and the first pressure sensor detects the pressure between the magnetic core 1 and the polishing member 5. The second pressure sensor can be arranged in the second movable member 4, and the second pressure sensor detects the pressure between the cover plate 2 and the polishing member 5.

[0023] It is very important that during long-term use, the grinding member 5 will wear and tear, and the vertical height of the grinding member 5 will decrease after wear and tear. Therefore, if the first moving member 3 and the second moving member 4 are set to move a fixed distance in the vertical direction, that is, the first moving member 3 and the second moving member 4 move the same distance in the vertical direction each time, then at the beginning, the magnetic core 1 and the cover plate 2 can be well polished with the grinding member 5, but after a period of time, due to the wear of the grinding member 5, the grinding effect of the magnetic core 1 and the cover plate 2 will become worse and worse. In this embodiment, the pressure detected by the pressure sensor is used to control the distance moved by the first moving member 3 and the second moving member 4 in the vertical direction, that is, the pressure between the magnetic core 1, the cover plate 2 and the grinding member 5 is moderate, and then the first moving member 3 and the second moving member 4 stop moving.

[0024] In addition, the fixing method of the first moving member 3 and the magnetic core 1, and the fixing method of the second moving member 4 and the cover plate 2 can be achieved by negative pressure adsorption, and of course, can also be achieved by clamping, bonding, etc., which is not limited in this embodiment.

[0025] It can be imagined that in order to improve the grinding effect of the magnetic core 1, the cover plate 2 and the grinding piece 5, in this embodiment, the grinding and gluing device further includes a liquid spraying member 7, the liquid spraying member 7 is located on one side or both sides of the grinding piece 5, and the liquid spraying port of the liquid spraying member 7 is arranged toward the grinding piece 5. The liquid spraying member 7 can spray at least one of the cutting fluid and the coolant on the magnetic core 1, the cover plate 2 and the grinding piece 5.

[0026] It is conceivable that the grinding piece 5 will be worn out during long-term operation. In order to increase the service life of the grinding piece 5, in this embodiment, the grinding piece 5 is H-shaped, and there is a gap between the first grinding plate 51 and the second grinding plate 52.

[0027] Specifically, the parts of the magnetic core 1 that need to be polished are the lower sides of the first plate 11 and the second plate 12, and the parts of the cover plate 2 that need to be polished are the first polishing area 21 and the second polishing area 22, that is, the magnetic core 1 and the cover plate 2 only need to be polished in part, and the present embodiment uses the first polishing plate 51 and the second polishing plate 52 that are arranged at intervals to achieve precise polishing, and the gap between the first polishing plate 51 and the second polishing plate 52 can reduce the overall mass of the polished piece 5, thereby reducing costs. Secondly, even if the first polishing plate 51 and the second polishing plate 52 that are arranged at intervals are worn, as long as the moving distance of the first movable member 3 and the second movable member 4 in the vertical direction is increased, the magnetic core 1 and the cover plate 2 can still be brought into contact with the polished piece 5, thereby not affecting the polishing of the magnetic core 1 and the cover plate 2. If the grinding piece 5 is in a rectangular shape, the grinding area with the magnetic core 1 and the cover plate 2 will gradually sink during a long grinding process, and the middle part will bulge. If the bulged middle part abuts against the middle part of the magnetic core 1 and the cover plate 2, the grinding area of ​​the magnetic core 1 and the cover plate 2 cannot abut against the grinding piece 5 normally, and thus cannot be polished normally. The H-shaped grinding piece 5 of this embodiment can solve the above problem, thereby greatly improving the service life of the grinding piece 5.

[0028] In addition, the first movable part 3 and the second movable part 4 may be provided with a first temperature sensor and a second temperature sensor respectively. The first temperature sensor can detect the temperature of the magnetic core 1 and the second temperature sensor can detect the temperature of the cover plate 2 to prevent the temperature abnormalities of the magnetic core 1 and the cover plate 2 from affecting the bonding between the two.

[0029] In addition, according to actual needs, the material of the grinding piece 5 is not limited. For example, the grinding piece 5 can be made of different materials such as corundum and silicon carbide.

[0030] This embodiment also provides a grinding and gluing process for a magnetic core and a cover plate, including: S1, along the horizontal direction, multiple magnetic cores 1 are fixed to the first moving member 3, and multiple cover plates 2 are fixed to the second moving member 4; S2, the first moving member 3 moves downward along the vertical direction until the magnetic core 1 abuts against the polishing member 5, and the second moving member 4 moves upward along the vertical direction until the cover plate 2 abuts against the polishing member 5; S3, the first moving member 3 and the second moving member 4 move in the horizontal direction until the magnetic core 1, the cover plate 2 and the polishing member 5 are separated; S4, cleaning the glue-coated member 6, first blowing air on the magnetic core 1 and the cover plate 2, until the surfaces of the magnetic core 1 and the cover plate 2 are free of impurities and the temperature is moderate, cleaning the glue-coated member 6, and then applying glue to the first polishing area 21 and the second polishing area 22 of the cover plate 2; S5 , the first moving member 3 moves downward in the vertical direction, and the second moving member 4 moves upward in the vertical direction, until the first plate 11 is bonded to the first grinding area 21 , and the second plate 12 is bonded to the second grinding area 22 .

[0031] In step S2 , the first pressure sensor detects the pressure between the magnetic core 1 and the polishing piece 5 , and the second pressure sensor detects the pressure between the cover plate 2 and the polishing piece 5 .

[0032] In step S3 , the liquid spraying component 7 sprays at least one of a cutting fluid and a cooling fluid on the magnetic core 1 , the cover plate 2 , and the polishing component 5 .

[0033] In step S4 , before cleaning and gluing the glue-coated member 6 , the first temperature sensor detects the temperature of the magnetic core 1 , and the second temperature sensor detects the temperature of the cover plate 2 .

[0034] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
