The terms are used solely to distinguish one component from another. For example, a first component could be referred to as a second component, and similarly, a second component could be referred to as a first component without departing from the teachings of the utility model. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0025] The terms used herein are for the purpose of describing various embodiments only and are not intended to be limiting. As used herein, the singular is intended to include the plural, unless the context clearly indicates otherwise. It will also be understood that the terms "comprising" and / or "having" when used in this specification specify the presence of a stated feature, number, step, operation, component, element, or combination thereof, and do not preclude the presence or addition of one or more other features, numbers, steps, operations, components, elements, or groups thereof.

[0026] refer to Figures 1 to 4 According to a preferred embodiment of the present invention, a PCB solder paste brushing baffle is provided. It should be noted that the structure of the PCB solder paste brushing baffle is shown in FIG. X and is provided on an external circuit board. Specifically, the present invention is used to be placed on the upper side of a PCB board and directly facing the PCB board 100 to facilitate brushing solder paste on the PCB board 100. Specifically, the baffle includes a housing 10 having an opening and a cavity 101. The opening is connected to the cavity 101, and the cavity 101 is also connected to the outside.

[0027] The center of the bottom wall forming the cavity 101 also has a plurality of spaced-apart tin brushing grooves 102, and the plurality of tin brushing grooves 102 all penetrate the housing 10. It should be understood by those skilled in the art that the area of ​​the PCB board that needs to be tinned needs to face the plurality of tin brushing grooves 102, and the PCB is also located on the bottom wall of the housing 10, that is, on the side away from the opening. In addition, solder paste is placed on the bottom wall forming the cavity 101 and squeezed toward the plurality of tin brushing grooves 102 through an external hanging plate, so that the solder paste can be guided to the area of ​​the PCB board that needs to be tinned through the plurality of tin brushing grooves 102. However, when the bottom thickness of the housing 10 is relatively thin, the wall surface of the bottom of the housing 10 is more likely to deform, making it difficult for the user to place the housing 10 horizontally. As a result, the plurality of tin brushing grooves 102 cannot effectively face the area that needs to be tinned. Moreover, since the PCB board is only placed on the bottom of the housing 10 and there is no positioning device, the position of the PCB board cannot be effectively defined, making it difficult for the user to locate the position of the PCB board. In view of the above problems, the present application effectively solves the problem of being unable to define the position of the PCB board.

[0028] That is, the PCB solder paste brushing baffle further includes a plurality of positioning components 20 , which are arranged in a rectangular array and are all located outside the plurality of solder brushing slots 102 .

[0029] Furthermore, the bottom wall forming the cavity 101 also has a plurality of evenly distributed first positioning holes 103, and the plurality of first positioning holes 103 all penetrate the shell 10, and the plurality of first positioning holes 103 are in a rectangular array and are all located on the outside of the plurality of tin brush troughs 102, and the plurality of positioning components 20 respectively cooperate with the plurality of first positioning holes 103.

[0030] Specifically, each positioning assembly 20 includes an insertion rod 21 having an insertion portion 211, a first connecting portion 212, a second connecting portion 213, and a rotating portion 214. One end of the rotating portion 214 is connected to one end of the second connecting portion 213, the other end of the second connecting portion 213 is connected to one end of the first connecting portion 212, and the other end of the first connecting portion 212 is connected to one end of the insertion portion 211. It should be noted that the PCB board has at least two second positioning holes 1001 for locating the position of the PCB board, and the end of the insertion portion 211 facing away from the first connecting portion 212 is configured to cooperate with the corresponding second positioning hole 1001, thereby defining the position of the PCB board.

[0031] Furthermore, the insertion portion 211, the first connection portion 212, the second connection portion 213, and the rotating portion 214 are integrally formed. The cross-sectional dimensions of the first connection portion 212 are consistent with those of the insertion portion 211, while the cross-sectional dimensions of the second connection portion 213 are larger than those of the first connection portion 212. Furthermore, the cross-sectional dimensions of the rotating portion 214 are larger than those of the second connection portion 213. Furthermore, the outer wall of the first connection portion 212 is provided with external threads, and the first positioning hole 103 is a threaded hole. Specifically, the insertion portion 211 passes through the first positioning hole 103 and moves a predetermined distance toward the bottom of the housing 10. Simultaneously, the first connection portion 212 is threadedly connected to the first positioning hole 103, and the side of the second connection portion 213 closest to the first connection portion 212 is separated by a predetermined distance from the bottom wall forming the cavity 101. In other words, the length of the external threads determines the movement distance of the insertion rod 21, and a user can rotate the insertion rod 21 by gripping the rotating portion 214.

[0032] Furthermore, the positioning assembly 20 also includes a connecting block 22, which is threadedly connected to the end of the insertion portion 211 that is away from the first connecting portion 212. Specifically, the end of the insertion portion 211 that is away from the first connecting portion 212 has a connecting hole, and one side of the connecting block 22 has a protrusion, which is threadedly connected to the connecting hole, so that the side of the connecting block 22 provided with the protrusion can fit the wall surface of the insertion portion 211 provided with the connecting hole. Specifically, when the user rotates the above-mentioned rotating part 214, the connecting block 22 will move downward a predetermined distance until it matches the second positioning hole 1001, thereby defining the position of the PCB board. In addition, the outer wall of the connecting block 22 also has an annular abutment 221, the size of which is larger than the size of the first positioning hole 103, thereby preventing the insertion rod 21 from disengaging from the first positioning hole 103.

[0033] Specifically, the positioning assembly 20 also includes an elastic member 23, which is sleeved on the second connecting portion 213, and one end of the elastic member 23 abuts on the rotating portion 214, and the other end abuts on the bottom wall forming the cavity 101, that is, when the user reverses the insertion rod 21, the first connecting portion 212 will disengage from the first positioning hole 103, and the elastic member 23 applies a force to the rotating portion 214 so that the insertion rod 21 will move upward, thereby causing the connecting block 22 to quickly leave the second positioning hole 1001, and the elastic member 23 can also prevent the connecting block 22 from moving downward due to gravity. At the same time, the above-mentioned annular abutment portion 221 also limits the upward movement distance of the insertion rod 21, so that the elastic member 23 will not cause the insertion rod 21 to disengage from the corresponding first positioning hole 103.

[0034] In summary, the PCB board brush solder paste baffle based on the embodiment of the present application is explained, which provides the PCB board brush solder paste baffle with advantages such as easy use, convenient PCB board positioning, and high practicality.

[0035] It is worth mentioning that in the embodiments of the present application, the PCB solder paste baffle has a simple structure, does not involve complex manufacturing processes and expensive materials, and is highly economical. Furthermore, for manufacturers, the PCB solder paste baffle provided in the present application is easy to produce and is low-cost, which is more conducive to controlling production costs and further promoting product promotion and use.
