Pcb board Chinese is known as printed circuit board, also known as printed circuit board, printed wiring board, is important electronic component, is The supporter of electronic component is the supplier of electronic component electrical connection.In the workshop of electronic product, pcb board is needed It could complete to produce by multiple tracks production processes such as welding electronic chip, welding leads.The welding of pcb board generally uses wave crest Welding.Wave soldering is that we produce process very crucial together in assembling process, and the quality of wave soldering quality is directly Affect the quality of complete product.Therefore, wave soldering process is always one of the critical process of priority control in production process.

Wave soldering is the main reason for generating PCB component defect, and defect caused by it is up in entire assembling process 50%.When PCB has thousands of a solder joints, welding must have very high success rate.It is substantially all during wave soldering It is to be carried out on PCB, thereby it is ensured that the stability of pcb board is extremely important.Currently, to guarantee that pcb board is fixed, lead to It is assisted frequently with pcb board welding fixture.Pcb board jig includes jig plate and the frame for being set to jig plate surrounding, but is passed The shortcomings that jig frame of system mostly uses solid profile to be made greatly, solid profile has: weight is big；It is hard when auger shell wire hole, quite Trouble；Intensity is low.

Utility model content

In view of the deficiencies of the prior art, the purpose of this utility model is to provide a kind of pcb board welding fixture, use is hollow Profile makes jig frame, saves material, mitigates weight, and directly punches on profile, more convenient, and intensity is high, uses Service life is long.

To achieve the above object, the utility model provides the following technical solutions: a kind of pcb board welding fixture, including jig Main body and jig frame, the jig main body are equipped at least one PCB type chamber, and for placing pcb board, the PCB type chamber is leaned on The side of nearly jig frame is equipped with PCB briquetting, and the PCB briquetting is rotatably arranged on the outside of PCB type chamber, the jig side Frame is arranged around jig main body surrounding, and the jig frame is made of hollow profile, and jig frame upper surface is drilled with Screw hole.

Preferably, the PCB briquetting is provided with multiple altogether, and surrounding that is uniform, being symmetrically distributed in PCB type chamber.

Preferably, the PCB briquetting includes fixing bolt, spring and fixed block, and the fixing bolt is arranged in jig master On body, on fixing bolt, the fixed block covers outside fixing bolt and spring the spring pocket.

Preferably, the bottom surface both side of the fixed block is provided with lug boss, for pushing down pcb board edge, plays fixed work With.

Preferably, the jig main body is square structure, and the jig frame is composed of four gear tin bars.

Preferably, multiple equally distributed screw holes are provided on each gear tin bar of the jig frame, for inserting Enter screw, jig main body is fixed.The quantity of screw hole can be selected according to the length of gear tin bar.

Preferably, the distance between two neighboring described screw hole 5 is 80mm.

Compared with prior art, the utility model has the beneficial effects that the pcb board welding fixture, jig frame is using empty Cardioid material is made, and has not only saved material, has mitigated weight, but also has facilitated drilling；Rotatable PCB briquetting is arranged in PCB type chamber surrounding, with Briquetting rotates compression or release, it can be achieved that PCB, facilitates operation, and briquetting is uniformly arranged, so that pcb board uniform stressed； In addition, pcb board can be fixed with screw, it is easy to operate, and the screw hole on jig frame is uniformly arranged, so that jig main body After fixation can uniform stressed, guarantee its planarization.
