Abstract
Description
Technical Field
[0001] This utility model relates to a PCB board clamp. Background Technology
[0002] A printed circuit board (PCB) is an important electronic component. It serves as the support for electronic components and provides electrical connections between them. A PCB includes pads, vias, solder mask, and silkscreen printing.
[0003] Because PCB surfaces and vias are often not thoroughly cleaned, poor soldering or even scrapping of PCBs can easily occur. Therefore, PCBs that are not properly cleaned need to be rewashed, typically resulting in a rewash rate of 1% to 1.5%. During rewashing, the PCB is clamped in a specialized fixture and immersed in a dedicated rewashing tank. Traditional fixtures used for PCB rewashing have inadequate structural designs, leading to incomplete cleaning, high PCB defect rates, and increased PCB production costs. Furthermore, existing fixtures can only clamp a single product at a time.
[0004] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a new type of PCB board clamp with greater industrial application value. Utility Model Content

[0029] Example
[0030] like Figure 1 and Figure 2As shown, a PCB board clamp can fix different products, including a fixing frame 1. A fixing mounting plate 2 is connected to the frame of the fixing frame 1. The fixing mounting plate 2 has several parallel and equidistant placement holes 3. The inner wall of the placement holes 3 has a sliding groove 4. A slider 5 is connected in the sliding groove 4. An upper clamping plate 6 is connected to the slider 5 in the placement hole 3. A clamping hole 7 is opened at the central axis of the upper clamping plate 6. An upper clamping assembly 8 is connected to the upper clamping plate 6 located on the side of the clamping hole 7. A liftable guide rod 9 passes through the upper clamping plate 6. A lower clamping plate 10 opposite to the upper clamping plate 6 is connected to the bottom end of the guide rod 9. A positioning groove 11 opposite to the clamping hole is opened on the lower clamping plate 10. A lower clamping assembly 12 is connected to the lower clamping plate 10 located on the side of the positioning groove 11. The placement holes 3 and the clamping holes 7 are both rectangular.
[0031] The fixed frame 1 described in this utility model is connected to a handle 13 at its upper end, which can facilitate the operation of the operator and make it easier for the operator to grasp.
[0032] Furthermore, the product can be completely protruded from the fixed mounting plate, allowing for thorough cleaning. A locking hole 14 is provided on the side of the placement hole 3, and a locking bolt 15 connected to the upper clamping plate 6 is connected inside the locking hole 14.
[0033] Specifically, the upper clamping plate is locked in place by locking bolts. When the upper clamping plate is moved down to the bottom by the locking bolts, the product is in its most protruding state, which is convenient for cleaning. When it is at the top, it is convenient for installation.
[0034] like Figure 5 and Figure 6 As shown, further, in conjunction with the clamping of the upper clamping assembly, the lower clamping assembly 12 includes a lower left clamping block 121 and a lower right clamping block 122. The left and right sides of the lower clamping plate 10 are respectively provided with a left recess 123 and a right recess 124. The left recess 123 and the right recess 124 are respectively connected to a left rotating shaft 125 and a right rotating shaft 126. The lower left clamping block 121 and the lower right clamping block 122 are respectively connected to the left rotating shaft 125 and the right rotating shaft 126. The lower clamping plate 10 located on the side of the positioning groove is provided with a fixing hole 128 for connecting and fixing the lower left and right clamping blocks. The lower left clamping block 121 and the lower right clamping block 122 are each connected with a fixing post 127 that engages with the fixing post.
[0035] In actual operation, the product is inserted into the lower clamping plate through the clamping hole and positioned by the positioning groove. Then, the lower left clamping block 121 and the lower right clamping block 122 fix the lower end of the product. Then, the operator lowers the product under the action of the guide rod so that the upper end of the product is submerged in the clamping hole, and waits for the upper clamping assembly to clamp.
[0036] For fixing different products, several fixing holes 128 are provided, which are equidistant from each other and arranged on the same axis. At the same time, the lower left clamping block 121 and the lower right clamping block 122 are both connected to their respective rotating shafts via telescopic rods. By adjusting the positions of the lower left clamping block 121 and the lower right clamping block 122 at different intervals using fixing holes with different spacing and telescopic rods, products of different sizes can be fixed.
[0037] Simultaneously, in addition to securing the product, the lower left clamping block 121 and lower right clamping block 122, which come into contact with the product, both have grooves, and a retaining spring 129 is connected inside each groove. This structure achieves secondary fixation of the product, improving the stability of the fixation.
[0038] like Figure 3 and Figure 4 As shown, further, to achieve the fixation of the upper end of the product, after the lower clamping assembly is used for fixation, the upper end is further fixed. The upper clamping assembly 8 includes an upper left clamping slider 81 and an upper right clamping slider 82 that slide in the clamping hole. A slot is provided at the central axis of the clamping hole. The upper left clamping slider 81 and the upper right clamping slider 82 are connected to a locking block 83 that engages with the slot by a spring. The upper left clamping slider 81 and the upper right clamping slider 82 that are in contact with the product have an inclined structure.
[0039] In specific operation, after the lower end of the product is fixed, the upper end of the product is fixed by sliding the upper left clamping slider 81 and the upper right clamping slider 82. During the sliding process, pressure is applied to the product through the tilting structure, thereby achieving the fixation of the upper and lower parts.
[0040] The working principle of this utility model is as follows:
[0041] In actual operation, after the product enters through the clamping hole, the lower end of the product contacts the lower clamping plate and is fixed by the lower clamping assembly. Then, the product is protruded from the bottom of the fixed frame by the guide rod, and the upper end of the product is fixed by the upper clamping assembly. After both the upper and lower ends are fixed, the upper clamping plate is also protruded from the fixed frame by the locking bolt, thereby achieving complete protrusion of the product and facilitating comprehensive cleaning of the product.
[0042] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0043] In the description of this application, it should be noted that the terms "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0044] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or vertical, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0045] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
