DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0026] Please refer to Figure 1-6 ;

[0027] The silver dipping mechanism described in the present invention is intended to provide a more convenient silver dipping method to improve work efficiency. In addition, the silver dipping mechanism is part of the silver dipping equipment. If the part is not mentioned, you can refer to the device of the prior art, which specifically includes a rotating device 1. The output end of the rotating device 1 is equipped with a linkage device 2 for providing a fixing force. The outer side of the linkage device 2 is provided with a fixed area 24 distributed along a straight line. In the initial state, the fixed area 24 corresponds to the conveying device of the magnetic core. The conveying device can be a combination of a vibration disk and several conveying channels. The output end of the conveying channel is distributed in a straight line corresponding to the fixed area 24. In addition, the placement position of the magnetic core is adjusted by the vibration disk to ensure that each magnetic core is facing the same position. Then the fixing force of the linkage device 2 acts on the fixed area 24, so that several magnetic cores are arranged in a straight line and fixed at the fixed area 24. It should be noted that since a partition is provided between several conveying channels to block two adjacent magnetic cores, the magnetic cores fixed at the fixed area 24 are also distributed in a straight line.

[0028] Then the silver dipping operation is carried out, specifically, silver dipping is required at two opposite angular positions of the ends of the magnetic core. The silver dipping process requires the magnetic core to be tilted and immersed in the silver paste. The rotating device 1 drives the linkage device 2 to rotate, and the fixed area 24 will also rotate with the linkage component, so that the tilted state of the magnetic core can be achieved. Then, the silver paste immersed at one angular position of the magnetic core is taken out to complete one step of the silver dipping operation. After that, the rotating device 1 drives the linkage device 2 to reverse, and the fixed area 24 will also follow the linkage device 2 to flip so that the position of the other corner of the magnetic core is in a tilted state, and is taken out after being immersed in the silver paste to complete the tilted silver dipping operation.

[0029] The utility model utilizes the rotating silver dipping method to easily realize the inclined silver dipping operation at the two angular positions of the magnetic core, which is more efficient and simplifies the silver dipping structure in the prior art. In this process, no consumables such as rubber plates are required, that is, no waste is generated, and production costs are effectively reduced.

[0030] The force provided by the linkage device 2 of the present invention can be provided in two ways. The first way is through magnetic attraction. For example, a magnetic conductive member is provided at the bottom of the fixing area 24. The magnetic conductive member is connected to the coil. When the power is turned on, the magnetic force is generated, thereby attracting the magnetic core. When the power is turned off, the magnetic force disappears, and the magnetic core can fall from the fixing area 24.

[0031] The second method is through vacuum adsorption. An adsorption belt or a plurality of adsorption holes are distributed in a straight line in the fixed area 24. The diameter of the adsorption hole does not exceed the area of ​​the magnetic end face. A negative pressure generator is provided in the linkage device 2 to provide vacuum adsorption force to the adsorption hole, thereby fixing the magnetic core in the fixed area 24. When the negative pressure generator is turned off and the adsorption force disappears, the magnetic core falls from the fixed area 24.

[0032] The above is merely an example, and there should be other implementation methods in actual production, so it should not be used as a limitation on the scope of protection.

[0033] One embodiment of the linkage device 2 of the present invention specifically includes a rotating shaft 21 and a fixed block 22. The fixed block 22 is installed on the rotating shaft 21 and extends along the direction of the rotating shaft 21. The necessary components for providing fixing force are installed inside the rotating shaft 21. Of course, these components involve air pipes or wires passing through the ends of the rotating shaft 21. In addition, the rotating device 1 will not rotate in the same direction infinitely, so there will be no knotting of the wires or air pipes; a "triangular" strip boss 23 is provided on the outside of the fixed block 22, and a fixing area 24 is formed at the end point of the strip boss 23. The above design can avoid contact between the linkage device 2 and the silver paste. Preferably, the width of the fixing area 24 is less than or equal to the length of the magnetic core.

[0034] The steps in the silver dipping process include obtaining the magnetic core, silver dipping operation, and drying the magnetic core. The obtaining the magnetic core and the silver dipping operation require the magnetic core to be driven, so a multi-axis moving device 3 is required. The multi-axis moving device 3 in this embodiment has at least two axial movement functions. The rotating device 1 is installed on the multi-axis moving device 3.

[0035] In this embodiment, the multi-axis moving device 3 has the ability to move in at least the X-axis and Z-axis directions. A silver storage device 4 is installed in the X-axis direction of the multi-axis moving device 3 for providing silver paste, and is provided with a plurality of silver dipping holes (not shown). The silver dipping holes correspond to the positions of the magnetic cores. The silver dipping holes are very small, and each silver dipping hole can only accommodate one magnetic core or only the part of the magnetic core that needs to be silver-dipped.

[0036] One embodiment of the silver storage device 4 specifically includes a silver storage tray 41, which contains silver paste. A cover plate 42 is provided on the silver storage tray 41, and a plurality of silver dipping holes are provided on the cover plate 42. A scraper assembly 43 is located above the cover plate 42. Before silver dipping, the silver paste covering the silver dipping holes may be uneven, which will affect the silver dipping effect. Therefore, the scraper assembly 43 is needed to flatten the silver paste on the silver dipping holes. In addition, since the rotating device 1 drives the magnetic core to rotate with a relatively large amplitude, in order to avoid touching the scraper assembly 43 and causing the magnetic core to fall, the scraper assembly 43 is always kept at a distance from the fixed area 24.

[0037] Furthermore, the scraper assembly 43 is installed on the X-axis moving end of the multi-axis moving device 3, and a Z-axis moving assembly is also installed on the moving end of the X-axis, and the rotating device 1 is installed on the Z-axis moving assembly. That is to say, when the X-axis moves, the scraper assembly 43 and the rotating device 1 will translate at the same time, that is, the scraper assembly 43 and the rotating device 1 remain relatively still in the horizontal plane, so that the interval setting can be always maintained, and there is no need to set up multiple sets of power components to drive the two devices to move separately, which can save costs.

[0038] One embodiment of the multi-axis moving device 3 of the present invention specifically includes a base plate 33, a silver storage device 4 is installed on the base plate 33, an X-axis moving assembly is installed at the bottom of the base plate 33, and specifically can be a combination of a motor 1 and a screw pair 1, a connecting base 431 is installed on the screw pair 1, and a Z-axis moving device and a scraper assembly 43 are installed on the connecting base 431, and a rotating device 1 is installed on the Z-axis moving assembly. It can be seen that the scraper assembly 43 and the rotating device 1 remain relatively stationary. When the X-axis moving device moves, the scraper assembly 43 and the Z-axis moving assembly move synchronously;

[0039] The Z-axis moving assembly in the present invention is relatively special, specifically comprising a second motor 321 and a second screw assembly 322. A horizontal plate 323 is mounted on the second screw assembly 322. Slide rails 324 are provided at both ends of the horizontal plate 323. Slide blocks 325 are fixed on both sides of the bottom plate 33. The rotating device 1 is mounted on both ends of the slide rails 324. The slide rails 324 are slidably connected to the slide blocks 325. In a conventional approach, the slide rails 324 are fixed, while the movable device is mounted on the slide blocks 325. The movable device is pushed to slide by the driving assembly. If this approach is used in the present application, additional push rods need to be provided at both ends of the horizontal plate 323 to connect with the rotating device 1, which is redundant.

[0040] In the present invention, the slider 325 is used to fix the slide rail 324 to move, thereby cleverly pushing the rotating device 1 to move longitudinally and simplifying the overall structure.

[0041] One embodiment of the scraper assembly 43 of the present invention includes a connecting base 431, both ends of the connecting base 431 extend to both sides of the silver storage tray 41, and mounting columns 432 are provided at both ends of the connecting base 431. Cylinders 433 are provided on the two mounting columns 432. A crossbeam 434 is connected between the two cylinders 433, and the crossbeam 434 is connected to a scraper body 435. The crossbeam 434 is driven to rise or fall by the two cylinders 433, so that the scraper body 435 contacts and separates from the cover plate 42, and at the same time, it is driven by the X-axis moving assembly to achieve horizontal movement to achieve the purpose of scraping.

[0042] The present invention also provides a silvering method, specifically, a spring-pressing part 436 is provided on the crossbeam 434, and a rolling part 437 is connected to the spring-pressing part 436. The rolling part 437 is located behind the scraper. The rolling part 437 can specifically be a roller adsorbed with silver paste. A slot is provided on the cover plate 42, and the slot stores silver paste. Under the action of the spring-pressing part 436, the rolling part 437 can go deep into the slot to pick up the silver paste, that is, the rolling part 437 and the scraper can be misaligned. After the rolling part 437 picks up the silver paste from the silver storage tray 41, the rolling component is driven by the X-axis moving component to be tightly attached to the surface of the cover plate 42 and pass through the silver dipping hole. It should be noted that the silver dipping hole has a accommodating space and can store a small amount of silver paste. It will be consumed after each silver dipping operation, so the rolling part 437 is needed to replenish the silver paste, and then the overflowed silver paste is scraped flat by the scraper body 435.

[0043] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0044] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.
