Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum substrate processing technology, and in particular to a tooling for spraying conformal coating on aluminum substrates. Background Technology
[0002] Aluminum substrate is a metal-based copper-clad board with good heat dissipation function. It is usually divided into single-sided, double-sided and multi-layer boards. Aluminum substrate is widely used in daily life, such as lighting, automotive electronics, communication and office equipment. Due to the increasing demand, the production pressure is also increasing. Painting aluminum substrate is an essential process in the existing process. In the existing painting process, stickers need to be applied to the protective points on the aluminum substrate before painting to achieve the purpose of protection. However, due to the poor consistency of the protective measures and the long application time, the process is out of sync with the production line and the long waiting time makes it impossible to achieve synchronous production, thus reducing production efficiency. In view of this, there is an urgent need for a tooling for spraying conformal coating on aluminum substrates to solve the above problems. Utility Model Content
[0003] The purpose of this invention is to provide a tooling for spraying conformal coating on aluminum substrates to solve the above-mentioned problems.
[0004] To achieve the above objectives, this utility model adopts the following technical solution: a tooling for spraying conformal coating on aluminum substrates, comprising: The components include a worktable, connecting components, limiting components, a supporting base plate, an aluminum substrate bracket, at least two aluminum substrates, and at least two aluminum substrate protective covers. The supporting base plate is movably connected to the worktable via the connecting components. The limiting components are movably connected to both the worktable and the supporting base plate. The aluminum substrates are connected to the supporting base plate via the aluminum substrate bracket. The aluminum substrate protective covers are detachably connected to the aluminum substrates.
[0005] Preferably, the connecting assembly includes an outer flange, an inner flange, and multiple fastening bolts. The outer flange is fixedly connected to the workbench surface by the fastening bolts, and the inner flange is fixedly connected to the bottom of the support base plate by the fastening bolts. The inner flange is fitted inside the outer flange, and the inner flange and the outer flange are clearance-fitted.
[0006] Preferably, the limiting assembly includes a limiting bracket, at least two limiting plates, and at least two spring plungers. The at least two limiting plates are fixedly connected to the edge of the supporting base plate in symmetrical positions, and the end of the limiting plate away from the supporting base plate is provided with a first screw hole. The limiting bracket is Z-shaped, with one end fixedly connected to the worktable surface and the other end provided with a limiting hole that matches the position of the first screw hole. The lower end of one of the spring plungers passes through the first screw hole and is located in the limiting hole, and the spring plunger is threadedly connected to the first screw hole.
[0007] Preferably, the limiting bracket is fixedly connected to the end of the worktable away from the spray gun, and the lower end of the spring plunger is away from the limiting hole in the compressed state.
[0008] Preferably, the aluminum substrate support includes multiple vertical connecting rods, one end of which is detachably connected to the support base plate and the other end is detachably connected to the aluminum substrate, and each aluminum substrate is connected to at least three vertical connecting rods.
[0009] Preferably, the aluminum substrate protective cover includes an irregularly shaped cover, multiple inner connecting posts, and at least two outer locking plates. The irregularly shaped cover covers the aluminum substrate. The two ends of the multiple inner connecting posts are detachably connected to the irregularly shaped cover and the aluminum substrate, respectively. The outer locking plates are shaped such that the portion located outside the irregularly shaped cover is detachably connected to the aluminum substrate, and the portion of the outer locking plates that contacts the irregularly shaped cover is detachably connected to the top wall of the irregularly shaped cover.
[0010] Preferably, the irregularly shaped cover and the outer locking plate are provided with multiple locking holes that match each other in position, and the locking holes are provided with locking pins that match them.
[0011] Compared with the prior art, the beneficial effects of this utility model are: In this application, an aluminum substrate protective cover is made to cover the aluminum substrate to protect the protected area on the aluminum substrate. This method makes full use of the easy disassembly and assembly characteristics of the aluminum substrate protective cover and the aluminum substrate, which greatly speeds up the replacement efficiency of the aluminum substrate protective cover, reduces waiting time, and further improves work efficiency.
[0012] In this utility model, the support base plate and the worktable are connected by a connecting component, so that the support base plate can rotate freely relative to the worktable. On this basis, at least two aluminum substrates are installed on the support base plate. The advantage of this setting is that when one aluminum substrate is being painted, it does not affect the disassembly and assembly of the other aluminum substrates. Thus, the waiting time for painting in the original process is integrated with the time for replacing aluminum substrates, thereby improving work efficiency. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0016] Please see the appendix Figure 1-2 A tooling for spraying conformal coating on aluminum substrates, comprising: The worktable 1, connecting component 2, limiting component 3, supporting base plate 4, aluminum substrate bracket 5, at least two aluminum substrates 6, and at least two aluminum substrate protective covers 7 are provided. The supporting base plate 4 is movably connected to the worktable 1 through the connecting component 2. The limiting component 3 is movably connected to both the worktable 1 and the supporting base plate 4. The aluminum substrates 6 are connected to the supporting base plate 4 through the aluminum substrate bracket 5. The aluminum substrate protective covers 7 are detachably connected to the aluminum substrates 6. In practical use, the connecting component 2 is used to connect the workbench 1 and the support base plate 4, so that the support base plate 4 can rotate freely relative to the workbench 1. At the same time, considering that the aluminum substrate 6 on the support base plate 4 must be stationary during the painting process, a limiting component 3 is set to restrict the position of the support base plate 4 to ensure that it remains stationary during the painting process. In addition, in order to improve the overall work efficiency, an aluminum substrate protective cover 7 matching the aluminum substrate 6 is set to replace the traditional process of protecting it with stickers, thereby reducing the preparation time of the protection stage.
[0017] Specifically, the connecting assembly 2 includes an outer flange 20, an inner flange 21, and multiple fastening bolts 22. The outer flange 20 is fixedly connected to the workbench 1 by the fastening bolts 22, and the inner flange 21 is fixedly connected to the bottom of the support base plate 4 by the fastening bolts 22. The inner flange 21 is fitted inside the outer flange 20, and the inner flange 21 and the outer flange 20 are clearance-fitted. Considering that the connecting assembly 2 is needed to allow the support base plate 4 to rotate freely relative to the workbench 1, the inner flange 21 is fitted inside the outer flange 20. The rotation of the inner flange 21 relative to the outer flange 20 drives the rotation of the support base plate 4. At the same time, the use of the inner flange 21 and the outer flange 20 also facilitates their connection to the support base plate 4 and the workbench 1 respectively by the fastening bolts 22.
[0018] Specifically, the limiting component 3 includes a limiting bracket 30, at least two limiting plates 31, and at least two spring plungers 32. At least two of the limiting plates 31 are symmetrically fixed to the edge of the supporting base plate 4, and each limiting plate 31 has a first screw hole 310 at its end away from the supporting base plate 4. The limiting bracket 30 is Z-shaped, with one end fixed to the worktable 1 and the other end having a limiting hole 300 matching the position of the first screw hole 310. The lower end of one of the spring plungers 32 passes through the first screw hole 310 and is located within the limiting hole 300, and the spring plunger 32 is threadedly connected to the first screw hole 310. Considering the… To prevent uneven painting caused by rotation during the painting process of the aluminum substrate 6, the position of the support base plate 4 is limited. This is achieved by installing a limiting bracket 30 on the worktable 1 and a limiting plate 31 on the support base plate 4 that matches the position of the limiting bracket 30. For ease of disassembly and assembly, a spring plunger 32 is used for position locking. It should be noted that the number and position of the limiting plates 31 are related to the number of aluminum substrates 6. For example, if two aluminum substrates 6 are installed on the support base plate 4, then two limiting plates 31 are set. If three aluminum substrates 6 are installed on the support base plate 4, then three limiting plates 31 are set evenly distributed, and so on.
[0019] Specifically, the limiting bracket 30 is fixedly connected to the end of the worktable 1 away from the spray gun; The lower end of the spring plunger 32 is away from the limiting hole 300 when compressed. Considering that the position of the worker disassembling and assembling the aluminum substrate 6 is away from the spray gun in the painting process, the limiting bracket 30 should also be fixedly connected to the workbench 1 away from the spray gun to facilitate the worker's disassembly and assembly of the aluminum substrate 6. At the same time, in order to facilitate the disassembly and assembly of the aluminum substrate 6, the application length of the spring plunger 32 also needs to be further limited. When the spring plunger 32 is in a compressed state, its lower end is away from the limiting hole 300 to facilitate the separation of the limiting bracket 30 and the limiting plate 31.
[0020] Specifically, the aluminum substrate support 5 includes multiple vertical connecting rods 50. One end of each vertical connecting rod 50 is detachably connected to the support base plate 4, and the other end is detachably connected to the aluminum substrate 6. Each aluminum substrate 6 is connected to at least three vertical connecting rods 50. The function of the aluminum substrate support 5 is to connect the aluminum substrate 6 and the support base 4. In this invention, multiple connecting rods 50 are used as the aluminum substrate support 5. Considering the balance of the aluminum substrate 6 and the convenience of disassembly and assembly, each aluminum substrate 6 uses three vertical connecting rods 50 to achieve the purpose of supporting the aluminum substrate 6. This setting not only fully considers the balance problem of the aluminum substrate 6, but also takes into account the time requirements for disassembly and assembly of the aluminum substrate 6, indirectly improving work efficiency. It should be noted that although multiple vertical connecting rods 50 are used as the aluminum substrate support 5 in this invention, it does not mean that this method can only be used. In practice, a frame structure can also be used to replace the structure of multiple vertical connecting rods 50.
[0021] Specifically, the aluminum substrate protective cover 7 includes an irregularly shaped cover 70, a plurality of inner connecting posts 71, and at least two outer locking plates 72. The irregularly shaped cover 70 covers the aluminum substrate 6. The two ends of the plurality of inner connecting posts 71 are detachably connected to the irregularly shaped cover 70 and the aluminum substrate 6, respectively. The outer locking plate 72 is shaped like a 7. Its outer portion is detachably connected to the aluminum substrate 6, and the contact portion between the outer locking plate 72 and the irregularly shaped cover 70 is detachably connected to the top wall of the irregularly shaped cover 70.
[0022] Specifically, the irregularly shaped cover 70 and the outer locking plate 72 are provided with a plurality of locking holes 700 that are matched in position, and the locking holes 700 are provided with locking pins 701 that match them. Considering the numerous drawbacks of the existing protective measures using stickers, a non-circular cover 70 with a fixed structure was adopted to replace the stickers. The non-circular cover 70 is fixed by the bottom and top of the inner connecting column 71 and the outer locking plate 72. Compared with the sticker method, this method provides stronger protection and also effectively improves work efficiency.
[0023] The implementation principle of the conformal coating spraying fixture for aluminum substrates in this utility model is as follows: In the use of the tooling, after one aluminum substrate 6 has been painted, the spring plunger 32 is pulled to disconnect the connection between the limiting bracket 30 and the limiting plate 31. The supporting base plate 4 is then rotated, causing the painted aluminum substrate 6 to rotate away from the spray gun. The spring plunger 32 then reconnects the limiting bracket 30 and the limiting plate 31, thus defining the position of the supporting base plate 4. At this point, the aluminum substrate 6 to be painted is within the working area of the spray gun, allowing the spray gun to paint the new aluminum substrate 6. During the painting process, the operator can remove the painted aluminum substrate 6 and replace it with a new one. This cycle can be repeated. Figure 1 The design adopts a method of setting two aluminum substrates 6 on a single support base plate 4. In practical applications, a structure with multiple aluminum substrates 6 can also be used, such as setting five aluminum substrates 6 on a single support base. In this case, the aluminum substrates 6 will not be removed immediately after the painting is completed. In this method, the conformal coating will be initially dried during the circulation process after the painting is completed.
[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
