Abstract
Description
Technical Field
[0001] This utility model relates to the field of PCB manufacturing technology, specifically to a dehumidification board placement mechanism and a dehumidifier. Background Technology
[0002] PCB dehumidification is a process of removing moisture from the surface of a PCB board. Especially after the electroplating process, in order to prevent the electrolytic solution after electroplating from adhering to the PCB surface and dripping during PCB transportation, the PCB board often needs to be dehumidified before transportation to facilitate the transfer of the PCB board.
[0003] In existing technologies, the mechanisms used to store PCB boards in dehumidification devices are generally designed for horizontal or vertical placement of the PCB boards, which often suffer from the following drawbacks:
[0004] 1. Mechanisms used for horizontal placement of PCB boards make it difficult to drain the electroplating electrolyte solution adhering to the PCB board after it is stored. During the dehumidification process, due to the large amount of solution adhering to the PCB board surface, it often requires a large amount of power or a long time to achieve dehumidification of the PCB board, thus affecting the overall production efficiency of the PCB board.
[0005] 2. Mechanisms used for vertical placement of PCBs often cause deformation of the PCBs due to gravity after they are stored, which in turn affects the overall quality of PCB production.
[0006] 3. Since PCBs are generally manufactured as a single board with a large overall area, if a vertical placement mechanism is used for storage, there are often significant limitations on the height of the mechanism. Otherwise, the PCB board may be difficult to place due to the height of the mechanism. Utility Model Content
[0007] To address the shortcomings of the existing technology, this utility model provides a dehumidification board placement mechanism, a board placement assembly for placing PCBs, which consists of multiple parallel board placement units arranged at different heights and at a certain angle to the horizontal plane.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.
[0043] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0044] Example 1:
[0045] Please see the appendix Figure 1-2 The dehumidification plate placement mechanism 10 of this utility model embodiment includes a plate placement frame 100 for overall support of the mechanism, and a plate placement assembly 200 disposed on the plate placement frame 100 for layered placement and storage of multiple PCB boards; wherein, the plate placement assembly 200 includes at least 5 plate placement units 210 arranged in parallel at different heights on the plate placement frame 100, and the plane P formed by the plate placement units 210 forms an angle α with the horizontal plane L, 15°≤α≤60°.
[0046] In this embodiment, the dehumidification board placement mechanism 10 and board placement assembly 200 can not only simultaneously place and store multiple PCB boards, effectively ensuring the quantity of PCB boards placed and stored; but also, multiple board placement units 210 arranged at different heights on the board placement frame 100 can form an inclined structure at an angle α to the horizontal plane L. Compared with the mechanism for horizontally placing PCB boards, the inclined board placement mechanism can not only effectively facilitate the drainage of liquid adhering to the surface of the stored PCB boards, thereby reducing the dehumidification time and improving the dehumidification efficiency of the PCB boards, but also prevent the stored PCB boards from moving, effectively ensuring the stability of the mechanism in placing and storing the PCB boards; and compared with the mechanism for vertically placing PCB boards, it can not only effectively reduce the probability of PCB board deformation during storage, thereby effectively ensuring the quality of PCB board dehumidification and overall production, but also effectively facilitate the storage of large-area PCB boards.
[0047] Please refer to the appendix for further details. Figure 3 In some embodiments, the plate holder 100 is a vertical plate holder structure, which specifically includes multiple support columns 110 for supporting the plate holder 100 as a whole, and a limiting plate 120 connected between two adjacent support columns 110 for fixing the plate holder 100 as a whole; preferably, the limiting plate 120 is provided at the top and bottom of the support columns 110.
[0048] Please refer to the appendix for further details. Figure 4 In some embodiments, the board placement unit 210 includes a first guide groove 211 and a second guide groove 212 parallel to the two inclined sides of the plane P and disposed on two opposite sides of the board placement unit 210, and a limiting strip 213 parallel to the bottom edge of the plane P and disposed on the board placement unit 210; wherein, the first guide groove 211 and the second guide groove 212 are used to realize the placement and height limitation of the PCB board; the limiting strip 213 is used to realize the complete limitation of the PCB board. When placing the PCB board, simply push the PCB board along the first guide groove 211 and the second guide groove 212 onto the limiting strip 213 to realize the placement and complete limitation of the PCB board.
[0049] Furthermore, the first guide groove 211 and the second guide groove 212 are L-shaped guide groove structures with an "L"-shaped cross-section, or flat guide groove structures with an "I"-shaped cross-section; the specific selection and design can be made according to actual needs, as long as it can achieve the limiting and guiding of the PCB board. However, in order to further prevent the PCB board from falling from the first guide groove 211 or the second guide groove 212 to the outside of the mechanism, preferably, the first guide groove 211 and the second guide groove 212 are L-shaped guide groove structures with an "L"-shaped cross-section, and the openings of the L-shaped guide groove structures are opposite each other and face the middle of the board holder 100. Furthermore, the limiting strip 213 is an L-shaped plate structure with an "L"-shaped cross section, and the opening of the L-shaped plate structure faces the first guide groove 211 and the second guide groove 212. When placing the PCB board, the PCB board can be pushed along the openings of the two opposing L-shaped guide groove structures to the opening of the L-shaped plate structure, so that the side of the PCB board abuts against the opening of the L-shaped guide groove structure and the L-shaped plate structure, thereby realizing the overall placement and limiting of the PCB board.
[0050] Please refer to the appendix for further details. Figure 4 In some embodiments, the limiting strip 213 is provided with multiple drainage holes 214 for draining accumulated liquid, thereby promoting the drainage of electroplating electrolyte solution. This effectively prevents the electroplating electrolyte solution flowing along the PCB board to the limiting strip 213 from accumulating on the limiting strip 213, which would not only easily cause uneven dehumidification efficiency in different parts of the PCB board, but also easily corrode the limiting strip 213. Furthermore, the drainage holes 214 are circular holes, elliptical holes, or square holes located at the bottom of the limiting strip 213; that is, the drainage holes 214 are circular holes, elliptical holes, or square holes located on the bottom sidewall of the limiting strip 213 of the L-shaped plate structure, and the specific selection and design can be made according to actual needs.
[0051] Please refer to the appendix for further details. Figure 4 In some embodiments, the placement unit 210 further includes a PCB board separator 215 disposed between the first guide groove 211 and the second guide groove 212 for placing the PCB board. The design of the PCB board separator 215 not only supports the placed PCB board to prevent deformation during placement and storage, but also allows the placement unit 210 with the PCB board separator 215 to effectively accommodate the placement of PCB boards of different sizes. In particular, when the size of the PCB board is smaller than the distance between the first guide groove 211 and the second guide groove 212, the PCB board can be placed and stored simply by placing it on the PCB board separator 215, without the need to use the first guide groove 211 and the second guide groove 212 for limiting and guiding.
[0052] Please refer to the appendix for further details. Figure 5In some embodiments, the PCB board separator 215 is a partition 2151 erected between the first guide groove 211 and the second guide groove 212, and the partition 2151 is provided with a plurality of filter holes 2152 for draining liquid adhering to the PCB board; or the PCB board separator 215 is a mesh 2153 erected between the first guide groove 211 and the second guide groove 212, as shown in the attached... Figure 4 As shown. The design of the partition plate 2151 and the mesh 2153 with the filter hole 2152 not only supports and places the PCB board, but also effectively facilitates the discharge of liquid adhering to the PCB board, and facilitates the dehumidification of the PCB board by the dehumidifying hot air or dehumidifying air volume in the dehumidifier, thereby improving the overall dehumidification efficiency of the PCB board; at the same time, the design of the filter hole 2152 and the mesh 2153 can also prevent the liquid from being trapped between the PCB board and the PCB board separator 215 and thus unable to be dehumidified.
[0053] Please see the appendix Figure 1 and 2 In some embodiments, the dehumidification plate holder mechanism 10 further includes a liquid collection tank 216 disposed at the bottom of the plate holder frame 100, for the centralized collection of liquid adhering to the PCB board, to prevent liquid from dripping directly from the PCB board onto the ground during the process of conveying to the dehumidifier and contaminating the production space. Preferably, the liquid collection tank 216 can be disposed on the plate holder frame 100, located below the plate holder assembly 200, or directly disposed at the bottom of the plate holder frame 100; as long as centralized collection of liquid can be achieved, the specific structure can be selected and designed according to the implementation requirements.
[0054] Example 2:
[0055] Please see the appendix Figure 6 The dehumidifier in this embodiment includes a dehumidifier body 20 for dehumidifying PCB boards, and a dehumidification plate placement mechanism 10, as described in Embodiment 1, disposed inside the dehumidifier body 20 for placing and storing the PCB boards to be dehumidified. The dehumidifier body 20 can be any existing device capable of dehumidification, and can be selected as a heating dehumidification device or a blowing dehumidification device according to actual needs. The structure of the dehumidifier body 20 is not the main inventive point of this technical solution, and therefore will not be described in detail here.
[0056] In this embodiment, the dehumidifier uses the dehumidification plate placement mechanism 10 of Embodiment 1 to place and store the PCB to be dehumidified. This not only effectively improves the overall dehumidification efficiency of the device, but also effectively ensures the quality of PCB dehumidification and the overall production of the PCB.
[0057] As can be seen from the technical solutions of the above embodiments, this utility model provides a dehumidification plate placement mechanism, which not only effectively facilitates the drainage of liquid adhering to the surface of the collected PCB board, thereby reducing the dehumidification time and improving the dehumidification efficiency of the PCB board, but also effectively reduces the probability of PCB board deformation during storage, thus effectively ensuring the quality of PCB board dehumidification and overall production. This utility model also provides a dehumidifier that uses the above-mentioned dehumidification plate placement mechanism to place and store the PCB to be dehumidified, which not only effectively improves the overall dehumidification efficiency of the device, but also effectively ensures the quality of PCB board dehumidification and overall PCB board production.
