In the vehicle power industry, high-heat-generating inductor and transformer components are often used, which are usually placed in corresponding receiving boxes during installation and then integrated on a printed circuit board. In order to dissipate heat of the inductor and the transformer element, the accommodating box for accommodating the inductor and the transformer element is attached to a shell of the vehicle-mounted power supply, and a heat conduction material needs to be coated on the surface of the accommodating box attached to the shell in the installation process so as to conduct heat sufficiently. However, since the inductance and the transformer element are not of the same height, and the space limitation of the vehicle in which the vehicle-mounted power supply is located also limits the size of the product, this results in a non-uniform height of the housing box in which the inductance and the transformer element are placed. Because the accommodating boxes for accommodating the inductor and the transformer elements are not on the same horizontal plane, when the surface of the accommodating box attached to the shell is coated with the heat conduction material, the existing coating device can only coat the surface of one accommodating box at a time, and the simultaneous coating operation on the surfaces of two or more accommodating boxes cannot be realized, so that the coating is not uniform, and the coating efficiency is low.
The application hopes to provide a scheme that can solve above-mentioned technical problem, and it can solve current coating device and can only apply paint a coating face that holds the box at every turn, can't realize simultaneously two or more the operation is applied paint with a brush to the coating face that holds the box, has led to applying paint the inhomogeneous and lower scheduling problem of efficiency of applying paint with a brush. The details of which will be set forth in the examples that follow.
Please refer to fig. 1, which is a schematic structural diagram of a coating apparatus according to an embodiment of the present application. As shown in fig. 1, the present application provides a coating apparatus 100 for coating surfaces of a plurality of housing boxes (not shown) with a heat conductive material, wherein the coating surfaces of the plurality of housing boxes have at least two different heights, i.e., the plurality of housing boxes include at least two coating surfaces having a preset height difference. It can also be described that the plurality of accommodating boxes at least comprises a plurality of first accommodating boxes and a plurality of second accommodating boxes, and the coating surfaces of the plurality of first accommodating boxes are different from the coating surfaces of the plurality of second accommodating boxes in height, i.e. the coating surfaces are not on the same horizontal plane, i.e. a preset height difference exists between the coating surfaces. For example, the first type of containment box may be defined as a containment box for housing an inductor, having a height H1, and the second type of containment box may be defined as a containment box for housing a transformer element, having a height H2, wherein H1 is smaller than H2, i.e. the coated side of the first type of containment box and the coated side of the second type of containment box are not on a horizontal plane, with a predetermined height difference between the coated sides (H2-H1).
In the present embodiment, the coating apparatus 100 includes a base assembly 10, a squeegee assembly 20, a connecting assembly 30, and a blade 50. Wherein, the base component 10 is used for placing and fixing the accommodating box, the connecting component 30 is detachably connected with the base component 10 and the painting net component 20 at the same time, the painting net component 20 can be rotatably connected with respect to the base component 10 through the connecting component 30, namely, the painting net component 20 can be opened or closed with respect to the base component 10 through the connecting component 30. In the present embodiment, the applicator assembly 20 comprises at least two applicators having a predetermined height difference, each of the applicators covering the application surface of at least one of the receiving boxes having the same height. The scraper 50 comprises at least two scraping surfaces 52 with a preset height difference, the height difference between the scraping surfaces 52 is matched with the height difference between the brushing screens, and the scraping surfaces 52 are matched with the brushing screens to simultaneously coat the heat-conducting materials onto the scraping surfaces with different heights through the corresponding brushing screens.
In the embodiment of the present application, the housing box is a housing for housing high heat-generating inductance and transformer components. It will be appreciated that the height of the housing box in which the inductor and transformer elements are placed is not the same, since the overall height of the inductor and transformer elements themselves is not the same. Because the inductor and the transformer element generate heat in the using process, in order to dissipate heat for the inductor and the transformer element, the accommodating box for accommodating the inductor and the transformer element needs to be attached to the aluminum shell of the vehicle-mounted power supply as much as possible, that is, the surface attached to the aluminum shell of the vehicle-mounted power supply in the accommodating box is the coating surface. Moreover, in order to sufficiently conduct heat between the accommodating box and the aluminum shell of the vehicle-mounted power supply, the coating surface of the accommodating box needs to be coated with the heat conduction material.
In the embodiment of the present application, the heat conductive material may be heat conductive silicone grease, heat conductive gel, or heat dissipating paste.
In other embodiments of the present application, a plurality of the accommodation boxes are mounted on a substrate 70 (see fig. 2), and the substrate 70 is fixedly mounted to the base assembly 10, that is, a plurality of the accommodation boxes are fixedly mounted to the base assembly 10 through the substrate 70. Specifically, the substrate 70 may be a Printed Circuit Board (PCB), which provides support for the accommodating box and also provides electrical connection between the inductor and the electronic components such as the transformer element. It is understood that the height of the coating face of the housing box refers to the distance between the coating face of the housing box with respect to the substrate 70. Since the heights of the housing boxes in which the inductor and the transformer element are placed are not uniform, the heights of the coated surfaces of the housing boxes are not uniform, and accordingly, there is a difference in height between the coated surface of the housing box in which the inductor is placed and the coated surface of the housing box in which the transformer element is placed.
It can be understood that, according to the actual needs of the product, the number of the painting nets may be two, and a preset height difference exists between the two painting nets, and each painting net covers the painting surface of at least one accommodating box with the same height. The number of said painting nets may also be three, three painting nets possibly being two of them coplanar, the other one not coplanar, or possibly three coplanar with each other, each of said painting nets covering at least one painting face of said containing box having the same height.
To sum up, the coating device 100 of this application is through apply paint the at least two of net subassembly 20 setting with a brush that has the difference in height of predetermineeing and apply paint the net with a brush and have, apply paint the net with a brush and can match not co-altitude and hold the box, every apply paint the net with a brush and cover at least one that has the same height hold the coating face of box, and through with a brush net assorted scraper 50 will the heat conduction material sees through the corresponding net with a brush and coats simultaneously to co-altitude and on the coating face of co-altitude, thereby has realized simultaneously to two or more the operation is applied paint with a brush to the coating face that holds the box, promotes the work efficiency in the production greatly. Moreover, the coating device 100 can also ensure the coating uniformity of the heat conducting material, avoid the hidden danger of incomplete coating and achieve better heat dissipation effect.

The support posts 13 are used to provide support for the substrate 70 to prevent the substrate 70 from deforming under the action of gravity. Specifically, the height between the supporting posts 13 and the bottom plate 11 is substantially equal to the height between the positioning block 12 and the bottom plate 11, and when the substrate 70 is mounted to the positioning block 12, since the accommodating box, and the electronic components such as the inductance and transformer elements are mounted on the substrate 70, if the supporting posts 13 are not supported and kept horizontal at other positions corresponding to the positioning block 12, the substrate 70 may be deformed by the gravity of the electronic components when only the positioning block 12 supports the two opposite sides of the substrate 70.
In the embodiment of the present application, as shown in fig. 2, the base assembly 10 further includes a supporting plate 14, and the supporting plate 14 may be a plate body integrally and fixedly installed at one end edge of the bottom plate 11. The support plate 14 is detachably connected to the connecting assembly 30, specifically, one side of the support plate 14 is fixedly installed at an edge of one end of the bottom plate 11, and the other side of the support plate 14 opposite to the connecting assembly 30 is detachably connected to the other side. It is understood that the connection manner between the supporting plate 14 and the bottom plate 11 may be a bolt connection, a snap connection, a rivet connection, etc., and the present application is not limited thereto.

Specifically, one surface of each reinforcing plate 15 is attached to and fixedly connected with the bottom plate 11, and the other adjacent surface is attached to and fixedly connected with the supporting plate 14. Also, when the reinforcing plate 15 is provided in plural number, the plural reinforcing plates 15 are simultaneously connected to the bottom plate 11 and the support plate 14 while being spaced apart from each other. For example, when the number of the reinforcing plates 15 is 2, one of the reinforcing plates 15 is detachably attached to one end of the supporting plate 14, and the other reinforcing plate 15 is detachably attached to the other end of the supporting plate 15. When the number of the reinforcing plates 15 is 3, two of the reinforcing plates 15 are detachably attached to opposite ends of the supporting plate 14, respectively, and the other reinforcing plate 15 is detachably attached to an intermediate position of the supporting plate 15.
Referring to fig. 4 and 5, fig. 4 is a schematic structural view of the magnetic support base shown in fig. 2, and fig. 5 is an exploded structural view of the magnetic support base shown in fig. 4. In the embodiment, the base assembly 10 further includes a magnetic bearing 16, and the magnetic bearing 16 is connected between the bottom plate 11 and the brush screen assembly 20 for keeping the brush screen assembly 20 in a stable state when the heat conductive material is coated. Specifically, in the embodiment of the present application, the magnetic bearing 16 includes two bearing seats 161, a fixing element 163 and a magnetic connecting element 165, where the two bearing seats 161 are detachably mounted on the bottom plate 11, specifically, each bearing seat 161 may be a plate body, and the two bearing seats 161 are arranged in parallel at intervals and detachably mounted on the other end of the bottom plate 11 opposite to the supporting plate 14. It is understood that the connection manner between the two supporting seats 161 and the bottom plate 11 may be a bolt connection, a snap connection, a rivet connection, etc., and the application is not limited thereto.
The fixing member 163 may be a plate body, which is detachably mounted on the two support seats 161, and a magnet is embedded in the fixing member 163. The magnetic connector 165 may be a plate that is detachably mounted to the frame 21 of the squeegee assembly 20. The magnetic attachment 165 is aligned with the position of the fixing 163. A magnet is embedded in the magnetic connector 165, and a magnetic attraction force is generated between the magnetic connector and the fixing member 163, so as to keep the brush net assembly 20 in a stable state when the heat conductive material is coated. Because the brushing net is required to be tightly attached to the coating surface of the corresponding accommodating box in order to control the coating thickness in the process of coating the heat conducting material, the magnet attraction force is used for replacing the manual pressing force, and the operation is convenient.
In other embodiments of the present invention, the two supporting seats 161 and the fixing element 163 may be integrally formed, and a formed part thereof is directly mounted and fixed on the bottom plate 11, and a magnet is embedded in the formed part for directly attracting the magnetic connecting element 165 mounted on the frame 21 of the brush net assembly 20, which is not particularly limited in this application.

The support bar 18 is used to support the squeegee assembly 20 to prevent the squeegee assembly 20 from rotating and falling when opened or closed. Specifically, because the squeegee assembly 20 is rotatable by the connection assembly 30, the squeegee assembly 20 may rotate and fall off due to gravity or operator error during opening or closing if not supported by external forces. Due to the supporting effect of the support bar 18 on the squeegee assembly 20, the squeegee assembly 20 is prevented from rotating and falling when opened or closed relative to the base assembly 10 during opening or closing of the squeegee assembly 20.
In the embodiment of the present application, the support rod 18 may be a hydraulic support rod, or may be a foldable support rod.

Specifically, as shown in fig. 6, the squeegee assembly 20 includes a frame 21, a spacer 22, a first squeegee mesh 23, and a second squeegee mesh 25. The frame 21 is a hollow frame structure, and may be made of an aluminum alloy material. The spacing bars 22 are installed in the hollow frame 21 to divide the frame 21 into two accommodating spaces with the same or different sizes. It is understood that the frame 21 and the spacer 22 may be formed by integral molding.
The first brushing screen 23 and the second brushing screen 25 are installed in the frame 21 and are respectively located at two opposite sides of the spacing bar 22. Moreover, the first brushing net 23 and the second brushing net 25 are respectively and fixedly connected with two opposite sides of the spacing bar 22, a preset height difference is formed between the first brushing net 23 and the second brushing net 25, and the first brushing net 23 and the second brushing net 25 respectively cover the coating surfaces of the accommodating boxes with the same preset height difference. That is, the two opposite ends of the spacer 22 are respectively connected to the two opposite sides of the frame 21, so as to partition the hollow frame 21 into two accommodating spaces, the sizes of the two accommodating spaces are respectively matched with the sizes of the first brushing net 23 and the second brushing net 25, and the first brushing net 23 and the second brushing net 25 are respectively installed in the two accommodating spaces and are respectively located at the two opposite sides of the spacer 22. At this time, a preset height difference exists between the first brushing screen 23 and the second brushing screen 25, that is, the screen surface of the first brushing screen 23 and the screen surface of the second brushing screen 25 are not on the same horizontal plane, and a stepped arrangement is formed between the two.
Referring back to fig. 1, in the embodiment of the present application, the connecting assembly 30 includes a first fixing plate 31, a second fixing plate 32, and at least one connecting member 34 connecting the first fixing plate 31 and the second fixing plate 32. The first fixing plate 31 is detachably connected to a side of the supporting plate 14 away from the bottom plate 11, specifically, one side of the supporting plate 14 is fixed to an end edge of the bottom plate 11, and the other side of the supporting plate 14 opposite to the first fixing plate 31 is detachably connected.
The second fixing plate 32 is detachably connected to the frame 21, wherein the second fixing plate 32 and the magnetic connecting member 165 are respectively located on different sides of the frame 21. Each of the connectors 34 is connected to the first fixing plate 31 and the second fixing plate 32 at the same time, and the second fixing plate 32 is rotatable relative to the first fixing plate 31 via the connector 34, so that the squeegee assembly 20 is rotatably connected to the base assembly 10 via the connecting assembly 30, that is, the squeegee assembly 20 is openable or closable relative to the base assembly 10 via the connecting assembly 30.
Referring to fig. 1 and 2, in the embodiment of the present application, for convenience of description, the doctor blade 50 includes two doctor surfaces 52 having a predetermined height difference, and the number of the squeegee webs of the squeegee assembly 20 is matched. It is understood that the number of the scraping surfaces 52 can be three, four, or other numbers, which is not specifically limited in this application.
Specifically, as shown in fig. 2 and 6, the scraper 50 includes a main body 51, two scraping surfaces 52 with a preset height difference, and a gap 54 between the two scraping surfaces 52, wherein the two scraping surfaces 52 are both located at one end of the main body 51 and are respectively located at two sides of the gap 54. A predetermined height difference is formed between the two brushing surfaces 52, that is, a stepped arrangement corresponding to the first brushing web 23 and the second brushing web 25 is also formed between the two brushing surfaces 52. The position of the notch 54 corresponds to the position of the spacer 22 and is in sliding fit with the spacer 22, i.e. the notch 54 is slidable relative to the spacer 22. Since the notches 54 are slidably engaged with the spacer 22, the spacer 22 functions as a guide rail, which not only guides the movement direction of the scraper 50, but also prevents the scraper 50 from shifting when scraping the heat conductive material on the first and second brushing nets 23 and 25. The height difference between the two coating surfaces 52 is matched to the height difference between the first and second brushing meshes 23, 25, for coating the heat-conducting material onto the coating surfaces of different heights simultaneously through the first and second brushing meshes 23, 25. When the scraper 50 is used to coat the heat-conducting material, the two scraping surfaces 52 are aligned with the first brushing web 23 and the second brushing web 25, respectively, the notch 54 is located on the spacer bar 22 and can slide along the spacer bar 22, and the scraping surfaces 52 start scraping the first brushing web 23 and the second brushing web 25 to coat the heat-conducting material onto the coating surfaces with different heights through the corresponding brushing webs simultaneously.
The coating apparatus 100 further includes a blade holder 60, and the blade holder 60 is fixedly mounted to the second fixing plate 32, for example, at one end position of the second fixing plate 32. The blade seat 60 is used for placing and fixing the blade 50.
