Description

PCB side spraying jig Technical Field The utility model relates to the technical field of PCB production, in particular to a PCB side spraying jig. Background The PCB needs to be sprayed with ink in the manufacturing process, such as circuit ink for transferring an electronic circuit pattern onto the PCB, solder resist ink for covering a precise electronic circuit to play a role in protection, character ink for making a surface mark of the PCB, and the like. After the PCB is fixed by the existing PCB spraying jig, ink is easily sprayed onto a functional area at the bottom of the PCB in the process of spraying ink to the side face of the PCB. Disclosure of utility model The utility model aims to solve the technical problem of providing the PCB side spraying jig which can prevent ink from being sprayed onto a PCB bottom functional area easily. In order to solve the technical problem, the technical scheme includes that the PCB side spraying jig comprises a main board, wherein the main board is provided with a working area for accommodating the PCB, the working area is matched with the PCB, a limiting structure for fixing the PCB on the working area is arranged on the working area, and an air blowing outlet is arranged on the side of the working area. Further, the main board is provided with an air flow groove and an air blowing hole, the air flow groove is communicated with the outer wall surface of the main board is provided with an opening for forming a blowing outlet, the air blowing hole is connected with the air flow groove. Further, the air flow groove is annular, and the air flow groove is arranged around the working area. Further, the width of the air blowing outlet is smaller than the maximum width of the cross section of the air flow groove. Furthermore, a guide channel is further formed in the main board, the guide channel is arranged on the inner side of the air flow groove and is communicated with the air flow groove, and the air blowing hole is communicated with the side face of the air flow groove through the guide channel. Further, the extending direction of the guide passage is inclined with respect to the normal direction at which the air flow groove communicates with the guide passage. Further, the guide passage communicates with the working area. Further, the limiting structure is a sucker, a claw, a clamping jaw or a movable pressing block. Further, at least one positioning hole is formed in the main board. Further, an avoidance structure for avoiding the functional area of the PCB is arranged on the working area. The PCB side spraying jig has the beneficial effects that the PCB is fixed on the working area of the main board by utilizing the limiting structure, and the air blowing outlet is utilized to blow air on the outer side of the PCB so as to change the movement track of part of ink, so that the ink is difficult to spray on the bottom functional area of the PCB. Drawings Fig. 1 is a top view of a PCB side spraying jig according to a first embodiment of the present utility model; Fig. 2 is a cross-sectional view of a PCB side painting jig according to a first embodiment of the present utility model. Description of the reference numerals: 1. a main board; 11, a working area, 12, a blowing outlet, 13, a positioning hole; 2. a limit structure; 3. A gas flow groove; 4. a blow hole; 5. And a guide channel. Detailed Description In order to describe the technical contents, the achieved objects and effects of the present utility model in detail, the following description will be made with reference to the embodiments in conjunction with the accompanying drawings. Referring to fig. 1 and 2, the side spraying jig for PCB includes a main board 1, the main board 1 has a working area 11 for placing PCB, the working area 11 is matched with the PCB, a limiting structure 2 for fixing the PCB on the working area 11 is disposed on the working area 11, and an air blowing outlet 12 is disposed outside the working area 11. As can be seen from the above description, the present PCB side painting jig has the advantages that the present PCB side painting jig fixes the PCB on the working area 11 of the main board 1 using the limiting structure 2, and blows air at the outside of the PCB using the blowing outlet 12 to change the movement trace of part of the ink, so that the ink is difficult to paint to the bottom functional area of the PCB. Further, the main board 1 is provided with an air flow groove 3 and an air blowing hole 4, the air flow groove 3 is communicated with an opening on the outer wall surface of the main board 1 to form an air blowing outlet 12, and the air blowing hole 4 is communicated with the air flow groove 3. As can be seen from the above description, the air flow blown out from the air blowing hole 4 is blown out from the air blowing outlet 12 of the air flow groove 3 to form a longer air wall, so as to increase the shielding range to the side of the PCB.
