Description

Technical Field

[0001] The present invention belongs to the technical field of magnetic core processing control methods, and specifically relates to an inclined silver dipping control method for magnetic cores. Background Art

[0002] The function of silver dipping for magnetic cores is to enhance their electrical conductivity and improve welding quality. Currently, the methods of silver dipping for magnetic cores are mainly electroplating and spraying. These two methods are more suitable for larger magnetic cores and are easier to operate. For smaller magnetic cores, silver paste needs to be used. The magnetic cores are tilted towards the silver paste so that the silver paste adheres to the positions of two corners of the magnetic cores. For example, in the publicly known technical document "CN204632724U, Device for Silver Dipping of Electronic Devices", the specific usage process can be known from paragraph 0049 of the specification of the reference document. A rubber plate needs to be used in the actual production, and the rubber plate is a consumable and needs to be replaced, thus increasing the processing cost. Moreover, a commutator needs to be used, and the operation process is relatively complex. Summary of the Invention

[0003] The purpose of the present invention is to provide an inclined silver dipping control method for magnetic cores to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solutions:

[0005] An inclined silver dipping control method for magnetic cores includes a conveying device. A multi-axis moving device, a silver storage device, and a drying device are installed at the output end of the conveying device. A silver dipping mechanism is installed at the moving end of the multi-axis moving device. The specific steps are as follows:

[0006] In the first step, a plurality of channels are arranged side by side at the conveying device. A plurality of magnetic cores are input into the channels through the conveying device and are finally placed side by side at the output port of the channels.

[0007] In the second step, the multi-axis moving device drives the silver dipping mechanism to obtain all the magnetic cores located at the output port at one time. The silver dipping mechanism includes a rotating device. A linkage device for providing a fixing force is installed at the output end of the rotating device. A fixed area is arranged along a straight line outside the linkage device. The fixing force acts on the fixed area to fix a plurality of magnetic cores in a straight line at the fixed area. The fixing force is magnetic attraction or negative pressure adsorption.

[0008] In the third step, after the silver dipping mechanism obtains a plurality of magnetic cores, it moves towards the silver storage device under the drive of the multi-axis moving device, and the magnetic cores are perpendicular to the plane of the silver dipping device. The silver storage device includes a silver storage tray. A cover plate is arranged on the silver storage tray. A plurality of silver dipping holes are arranged on the cover plate. A scraping plate assembly is arranged above the cover plate. The scraping plate assembly is used to scrape the silver paste in the silver dipping holes flat. The scraping plate assembly and the fixed area always maintain a spaced arrangement.

[0009] The fourth step is to drive the linkage device to rotate 30°-60° forward through the rotating device, so that the magnetic core is in an inclined state, and one corner of the magnetic core is perpendicular to the silver dipping hole. Then the multi-axis moving device drives the silver dipping mechanism to move up and down, so that one corner of the magnetic core enters and exits the silver dipping hole, and the silver dipping operation at one place is completed. Then the linkage device is driven to reverse 60°-120° through the rotating device, so that the magnetic core is in an inclined state, and the other corner of the magnetic core is perpendicular to the silver dipping hole. Then the multi-axis moving device drives the silver dipping mechanism to move up and down, so that another corner of the magnetic core enters and exits the silver dipping hole, and the silver dipping operation at another place is completed.

[0010] In the fifth step, the drying device is located above the silver storage device. The rotating device drives the linkage device to rotate so that the fixed area faces upward and is aligned with the edge of the drying device. At this time, the silver-stained surface of the magnetic core faces upward and the fixed surface faces downward. Then the magnetic core on the fixed area is pushed toward the drying device through the push plate assembly.

[0011] A further technical solution is based on the first step, in which a straightening component is provided in the conveying device, the width of the channel is slightly larger than the width of the magnetic core, and the straightening component is used to push a plurality of magnetic cores to one side for straightening and alignment.

[0012] According to a further technical solution, the linkage device includes a rotating shaft and a fixed block, wherein the fixed block is mounted on the rotating shaft and extends along the rotating shaft direction, and a "triangular" strip boss is provided on the outer side of the fixed block, and the fixed area is formed at the end point of the strip boss.

[0016] According to a further technical solution, the cross beam is further provided with a spring-pressing member, to which a rolling member is connected. The rolling member is located behind the scraper and is used to apply silver paste to the silver-dipping holes of the cover plate.

[0017] Further technical solution: The drying device is installed above the silver storage device. At the end of the Z-axis moving component facing the drying component, the Z-axis moving component includes a second motor and a second lead screw pair. A cross plate is installed on the second lead screw pair. Slide rails are provided at both ends of the cross plate. The slide rails are connected to sliders, and the sliders are fixedly arranged on external components. The rotating device is installed at both ends of the slide rails, and the two slide rails are respectively located on both sides of the drying device.

[0018] Further technical solution: The drying device includes a fixing frame. A conveyor belt, a dryer, and a placing plate are provided on the fixing frame. The placing plate is close to the conveyor belt and is flush with it. On the other side of the placing plate, there is a push plate assembly for pushing the magnetic cores on the fixing area onto the placing plate.

[0019] Further technical solution: At the output end of the conveying device, there is an aligning component for adjusting the position of the magnetic cores. The aligning component includes a first movable seat and a second movable seat distributed vertically.

Detailed implementation manners

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0039] Please refer to Figure 1-13 ;

[0040] The control method of the present invention can more conveniently perform the silver dipping operation on the magnetic core. The devices specifically required to be applied include a conveying device 6. A multi-axis moving device 3, a silver storage device 4, and a drying device 5 are installed at the output end of the conveying device 6. A silver dipping mechanism is installed at the moving end of the multi-axis moving device 3. The specific steps are as follows:

[0041] First step, a plurality of channels 611 are arranged side by side at the conveying device 6. A large number of magnetic cores are stored in the conveying device 6. Specifically, the magnetic cores can be output through a vibrating disk and enter the channels 611 in this way, and finally be placed side by side at the output port of the channels 611. Before outputting the magnetic cores, the range of the magnetic cores will be selected first to ensure that they can be output in the same orientation state. Currently, there are many ways to select the position of the magnetic cores in the prior art, which will not be elaborated here;

[0042] Second step, drive the silver dipping mechanism through the multi-axis moving device 3 to obtain all the magnetic cores located at the output port at one time; Refer to Figures 2-4, wherein the silver-dipping mechanism includes a rotating device 1. A linkage device 2 for providing a fixing force is installed at the output end of the rotating device 1. A fixing area 24 distributed along a straight line is provided outside the linkage device 2. The fixing force acts on the fixing area 24 to fix a number of magnetic cores in a straight line at the fixing area 24. The fixing force is magnetic attraction or negative pressure adsorption. It should be noted that there are many sizes of magnetic cores that can be obtained according to this structure. The smallest magnetic core in the shape of a "work" character has a length and width of 2.5mm X 1.5mm respectively. Of course, this is only an approximate value, indicating that the magnetic core is very small. At this time, the adsorption method or magnetic attraction method can be used to obtain it. If the size of the magnetic core is relatively large, the generated suction force is insufficient, and the magnetic attraction method can be selected for fixing. Of course, the magnetic attraction or negative pressure adsorption method is a choice between two, and structural adjustments are made according to specific situations;

[0043] In addition, the channel 611 is separated by a partition, so the obtained magnetic cores are naturally separated to avoid sticking to each other;

[0044] Furthermore, the force provided by the linkage device 2 has two methods. The first method is through magnetic attraction. For example, a magnetic conductive part is provided at the bottom of the fixing area 24. The magnetic conductive part is connected to a coil, and magnetic force is generated by energization to adsorb the magnetic core. When the power is cut off, the magnetic force disappears, and at this time the magnetic core can fall from the fixing area 24;

[0045] The second method is through vacuum adsorption. Adsorption belts or a number of adsorption holes are distributed along a straight line in the fixing area 24. The diameter of the adsorption holes does not exceed the area of the magnetic attraction end face. A negative pressure generator is provided in the linkage device 2 to provide a vacuum adsorption force to the adsorption holes, so as to fix the magnetic core at the fixing area 24. When the negative pressure generator is closed and the adsorption force disappears, the magnetic core falls from the fixing area 24.

[0046] However, the above is only an example for illustration, and there should be other implementation methods in actual production, so it should not be used as a limitation of the protection scope.

[0047] In the third step, after the silver-dipping mechanism obtains a number of magnetic cores, it moves in the direction of the silver storage device 4 driven by the multi-axis moving device 3, and the magnetic cores are perpendicular to the plane of the silver-dipping device. Refer to Figures 4-6, the silver storage device 4 includes a silver storage tray 41 which contains silver paste. A cover plate 42 is provided on the silver storage tray 41, and a number of silver dipping holes are provided on the cover plate 42. A scraper assembly 43 is provided above the cover plate 42. Before silver dipping, the silver paste covering the silver dipping holes may have an uneven problem, which will affect the silver dipping effect. Moreover, in order to avoid the situation of dripping slurry, there will only be a very thin layer of slurry each time. Therefore, the scraper assembly 43 is used to scrape the silver paste in the silver dipping holes flat. In addition, since the rotation 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 and the fixed area 24 are always kept at an interval.

[0048] In the fourth step, specifically, silver dipping needs to be performed at two opposite corner positions of the end of the magnetic core. Then, in the process of silver dipping, the magnetic core needs to be tilted and immersed in the silver paste. The rotation device 1 drives the linkage device 2 to rotate forward by 30° - 60°, so that the magnetic core is in an inclined state, and one of its corners is perpendicular to the silver dipping hole. Then, the multi-axis moving device 3 drives the silver dipping mechanism to move up and down, so that one corner of the magnetic core enters and exits the silver dipping hole to complete the silver dipping operation at one place. Then, the rotation device 1 drives the linkage device 2 to rotate backward by 60° - 120°, so that the magnetic core is in an inclined state, and the other corner of it is perpendicular to the silver dipping hole. Then, the multi-axis moving device 3 drives the silver dipping mechanism to move up and down, so that the other corner of the magnetic core enters and exits the silver dipping hole to complete the silver dipping operation at the other place.

[0049] In the fifth step, after the silver dipping operation, one end of the magnetic core away from the fixed area 24 has silver paste. At this time, the silver paste has not dried yet. If the fixing force of the silver dipping mechanism is cancelled, the magnetic core will directly fall, and the silver paste will adhere to the drying device 5, resulting in the reduction of the silver on the magnetic core, which is a defective product. In this embodiment, the drying device 5 is located above the silver storage device 4. The rotation device 1 drives the linkage device 2 to rotate so that the fixed area 24 faces upward and aligns with the edge of the drying device 5. At this time, the silver dipping surface of the magnetic core faces upward and the fixing surface faces downward. Then, the magnetic core on the fixed area 24 is pushed towards the drying device 5 through the push plate assembly 55.

[0050] Further, referring to Figure 7 , the drying device 5 includes a fixing frame 51. A conveyor belt 52, a dryer 53 and a placement plate 54 are provided on the fixing frame 51. The placement plate 54 is close to the conveyor belt 52 and is flush with it. A push plate assembly 55 is provided on the other side of the placement plate 54 for pushing the magnetic core on the fixed area 24 onto the placement plate 54.

[0051] Specifically, the multi-axis moving device 3 is used to drive the silver-dipping mechanism to move upward, and the rotating device 1 drives the linkage device 2 to rotate, so that the fixed area 24 is close to the side of the placement plate 54 close to the push plate assembly 55, and the fixed area 24 is flush with the placement plate 54. Then the linkage device 2 cancels the fixing force, and then the push plate assembly 55 is used to push the magnetic core toward the placement plate 54, and the magnetic core is located on the placement plate 54, and the placement plate 54 is used as a transition to push it toward the conveyor belt 52. After the magnetic core enters the conveyor belt 52, the silver-dipping end face faces upward and does not contact the conveyor belt 52, and during the conveying process, it will pass through the dryer 53 to dry the silver paste, and finally be sent out of the conveyor belt 52.

[0052] The present invention utilizes a rotating silver dipping method to easily achieve inclined silver dipping operations on 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 sheets are required, i.e. no waste is generated, thereby effectively reducing production costs.

[0053] In the process of the first step of the present invention, the width of the channel 611 is slightly larger than the width of the magnetic core, so there may be a problem of inconsistent direction of the output of the magnetic core. Therefore, a straightening component 62 is provided in the conveying device 6, and the straightening component 62 is used to push the plurality of magnetic cores to one side for straightening and alignment. Figure 8 and Figure 9 ;

[0054] More specifically, it includes a conveying plate 61, on which a plurality of conveying channels 611 are arranged side by side, a vibration disk is provided at one end of the conveying channel 611, and a moving component is provided at the bottom of the vibration disk. The moving component drives the vibration disk to move along the arrangement direction of the plurality of channels 611, so that the output end of the vibration disk passes through each conveying channel 611 in turn, and a magnetic core is input into each conveying channel 611.

[0055] In order to make it easier for the magnetic cores to enter the conveying channel 611 , the width of the conveying channel 611 is greater than the width of the magnetic cores, thereby causing the magnetic cores to be arranged neatly. For this purpose, a straightening component 62 for adjusting the position of the magnetic cores is provided at the output end of the conveying device 6 .

[0056] The alignment assembly 62 includes a movable seat 1 621 and a movable seat 2 622 which are arranged in an upper and lower manner, wherein the movable seat 1 621 and the conveying plate 61 are movable, and the conveying plate 61 is movable, and a plurality of magnetic core placement positions 623 are arranged on the upper end surface of the movable seat 1 621, and the bottom of the movable seat 2 622 is connected to the external component through a sliding pair 625;

[0057] It should be noted that magnetic core placement positions 623 are provided at both side edge positions on the upper part of the movable seat 1. However, only the side close to the channel 611 is used during application. If one side is worn or damaged, the movable seat 1 621 can be turned around to use the magnetic core placement position 623 on the other side; The movable seat 1 621 and the movable seat 2 622 are movably connected through a longitudinally arranged guide post 624, and a laterally arranged sliding pair 625 is connected to the bottom of the movable seat 2 622;

[0058] A fixed plate 626 is provided on the front side of the movable seat. Longitudinally extending limiting hole 1 6271 and laterally extending limiting hole 2 6272 are respectively provided on the fixed plate 626. The midpoint connection line of the limiting hole 1 6271 and the limiting hole 2 6272 is horizontal. A bearing 1 6273 and a bearing 2 6274 are respectively provided in the limiting hole 1 6271 and the limiting hole 2 6272. The bearing 1 6273 and the bearing 2 6274 are connected with a movable block 1 6275 and a movable block 2 6276. The movable block 1 6275 and the movable block 2 6276 are eccentrically connected to the output shafts of the motor 3 6277 and the motor 4 6278 respectively. It should be noted that the motor 3 6277 and the motor 4 6278 are fixed in position through an external bracket.

[0059] During operation, the motor 3 6277 drives the movable block 1 6275 to rotate. Since the movable block 1 6275 is eccentrically arranged and the limiting hole 1 6271 limits its horizontal direction, it will drive the movable seat 1 621 and the movable seat 2 622 to slide horizontally. And because the limiting hole 2 6272 is horizontally arranged, the movable block 2 6276 and the bearing 2 6274 can slide horizontally in the limiting hole 2 6272 during horizontal movement; That is, it drives the movable seat 1 621 and the movable seat 2 622 to slide horizontally back and forth. During this process, the magnetic core will move closer to the side of the conveying channel 611;

[0060] After that, the motor 3 6277 stops working, and the motor 4 6278 drives the movable block 2 6276 to rotate. Since the movable block 2 6276 is eccentrically arranged and the limiting hole 2 6272 limits its vertical direction, it will drive the movable seat 1 621 to move vertically relative to the movable seat 2 622. And because the limiting hole 1 6271 is vertically arranged, the movable block 1 6275 and the bearing 1 6273 can slide vertically in the limiting hole 1 6271 during vertical movement, that is, it drives the movable seat 1 621 to slide vertically back and forth relative to the movable seat 2 622. During this process, some inclined magnetic cores can be straightened.

[0061] It should be noted that the above is only an illustration of one implementation method, and does not limit the action sequence of the motor 3 6277 and the motor 4 6278.

[0062] One embodiment of the linkage device 2 of the present invention is referred to Figure 3, specifically including a rotating shaft 21 and a fixing block 22. The fixing block 22 is installed on the rotating shaft 21 and extends along the direction of the rotating shaft 21. 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 end of the rotating shaft 21. Additionally, the rotating device 1 will not rotate infinitely in the same direction, so the situation of wire or air pipe knotting will not occur. A strip-shaped boss 23 in the shape of a "triangle" is provided outside the fixing block 22, and a fixing area 24 is formed at the end point of the strip-shaped boss 23. With the above design, the linkage device 2 can be prevented from contacting the silver paste. Preferably, the width of the fixing area 24 is less than or equal to the length of the magnetic core.

[0063] In this embodiment, referring to Figure 4 and Figure 5 , the multi-axis moving device 3 has at least the ability to move in 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 a number of silver-dipping holes (not shown) are provided. 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 dipped in silver. The silver-dipping mechanism is installed on the moving end of the Z-axis. Preferably, a drying device 5 is installed above the silver storage device 4, at the end of the Z-axis moving component facing the drying component.

[0064] Furthermore, a scraper assembly 43 is installed on the X-axis moving end of the multi-axis moving device 3. A Z-axis moving component is also installed on the X-axis moving end. The rotating device 1 is installed on the Z-axis moving component. That is to say, when the X-axis moves, the scraper assembly 43 and the rotating device 1 will move horizontally at the same time, that is, the relative static state in the horizontal plane is maintained between the scraper assembly 43 and the rotating device 1. In this way, it can be ensured that the interval is always maintained, and there is no need to set multiple sets of power components to drive the two devices to act respectively, which can save costs.

[0065] One embodiment of the present invention regarding the scraper assembly 43 includes a connecting base 431. The two ends of the connecting base 431 extend to both sides of the silver storage tray 41. Mounting columns 432 are provided at both ends of the connecting base 431. Cylinders 433 are provided on both mounting columns 432. A cross beam 434 is connected between the two cylinders 433. The cross beam 434 is connected to a scraper body 435. By driving the cross beam 434 to rise or fall by the two cylinders 433, the scraper body 435 is brought into contact with and separated from the cover plate 42, and at the same time, horizontal movement is realized under the drive of the X-axis moving component to achieve the purpose of scraping flat.

[0066] The present invention also provides a silver application method. Specifically, a spring pressing member 436 is provided on the cross beam 434, and a rolling member 437 is connected to the spring pressing member 436. The rolling member 437 is located behind the squeegee. The rolling member 437 may 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 member 436, the rolling member 437 can penetrate into the slot to pick up the silver paste, that is, the rolling member 437 and the squeegee can be misaligned. After the rolling member 437 picks up the silver paste in the silver storage tray 41, under the drive of the X-axis moving component, the rolling component is closely attached to the surface of the cover plate 42 and passes through the silver application hole. It should be noted that the silver application hole has an accommodating space and can store a small amount of silver paste, which will be consumed after each silver application operation. Therefore, the rolling member 437 needs to replenish the silver paste, and then the overflowing silver paste is scraped flat by the squeegee body 435.

[0067] One embodiment of the multi-axis moving device 3 of the present invention specifically includes a bottom plate 33. The silver storage device 4 is installed on the bottom plate 33. An X-axis moving component is installed at the bottom of the bottom plate 33, which may specifically be a combination of a first motor and a first lead screw pair. A connection base 431 is installed on the first lead screw pair. A Z-axis moving device and a squeegee assembly 43 are installed on the connection base 431. The rotating device 1 is installed on the X-axis moving component. It can be seen that the squeegee assembly 43 and the rotating device 1 remain relatively stationary. When the X-axis moving device moves, the squeegee assembly 43 and the Z-axis moving component move synchronously.

[0068] The Z-axis moving component in the present invention is quite special. Refer to Figure 5 , specifically including a second motor 321 and a second lead screw pair 322. A cross plate 323 is installed on the second lead screw pair 322. Slide rails 324 are provided at both ends of the cross plate 323. Sliders 325 are fixedly provided on both sides of the bottom plate 33. The rotating device 1 is installed at both ends of the slide rails 324, and the slide rails 324 are slidably connected to the sliders 325. The traditional method is that the slide rails 324 are fixed and the moving device is installed on the sliders 325, and the moving device is pushed to slide by a driving component. If this method is applied to this application, it is necessary to additionally provide push rods at both ends of the cross plate 323 to connect with the rotating device 1, which is unnecessary.

[0069] In the present invention, by adopting the method of fixing the sliders 325 and moving the slide rails 324, the rotating device 1 is cleverly pushed to move longitudinally, and the overall structure is also simplified.
