Description

Technical Field

[0001] The utility model relates to the technical field of circuit board welding, and in particular mainly to a welding jig. Background Art

[0002] During the circuit design process, it is necessary to weld the experimental board according to the design ideas to verify whether the function of the designed circuit is normal. The welding at this stage is mainly completed by manual welding with a handheld soldering iron. The process is as follows: insert the components on the front of the circuit board, then turn the circuit board over, and solder and fix it on the back. During this process, when the plug-in circuit board is turned over, if there is any shaking, the components will become loose or fall off. In addition, since the soldering iron and solder wire need to be held, the circuit board can only be placed on the operating table without a fixed position after being turned over. A slight touch will cause the circuit board to shift, causing the position of the inserted components to change, affecting the welding effect. Therefore, a welding fixture is required.

[0003] At present, in the prior art, for example, a Chinese patent with announcement number CN214481553U discloses a circuit board welding jig, which is provided with a supporting device, wherein the supporting device is provided with a supporting column, one end of the supporting column is fixedly connected to the back of the supporting plate by screws through a fixing block and a fixing plate, and the other end is plastically connected to a connecting rod through a mold, and a card slot is provided at the upper end of the supporting column, and a worker can insert one end of a supporting wire into the card slot and support the workbench with the other end, and the worker can adjust the height of the workbench by inserting the supporting wire into the card slots at different positions. However, during use of the device, the circuit board needs to be turned over, the circuit board needs to be fixed, and then the circuit board needs to be welded, which reduces the work efficiency. In view of this, we propose a welding jig. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a welding jig.

[0005] The utility model discloses a welding fixture comprising a bottom plate, the bottom plate is hinged with a rotating plate, the inner surface of the rotating plate is rotatably connected with a support frame, a fixing component is magnetically attracted on the outer wall of the support frame, the inner surface of the support frame is slidably connected with a support component, a support frame is hinged on the outer wall of the rotating plate, a limit component is arranged in the rotating plate, and the limit component comprises:

[0006] A sliding block, wherein the sliding block is slidably connected in an inner groove of the supporting frame;

[0007] An insertion rod, the insertion rod is fixedly connected to the outer wall of the sliding block;

[0008] A pull rod, the pull rod being fixedly connected to the outer wall of the insertion rod;

[0009] and a compression spring, wherein the compression spring is fixedly connected to the outer wall of the sliding block.

[0010] Preferably, the fixing assembly comprises a magnetic block, a fixing plate is fixedly connected to the outer wall of the magnetic block, a bolt is threadedly connected to the fixing plate, and a clamping block is rotatably connected to the bottom of the bolt.

[0011] Preferably, the support assembly comprises a support bar, both ends of which are fixedly connected to limit blocks, and the support bar is penetrated by a push rod and is slidably connected to the push rod.

[0012] Preferably, the push rod is hinged with a hinge rod, and one end of the hinge rod away from the push rod is hinged with a slide plate, and the slide plate is slidably connected to the inner wall of the support bar.

[0013] Preferably, a fixing block is fixedly connected to the inner wall of the support bar, and the fixing block is elastically connected to the slide plate via a connecting spring.

[0014] Preferably, a cross bar is fixedly connected to the outer wall of the slide plate, and the cross bar passes through the limit block and is slidably connected to the limit block.

[0016] Preferably, a slide groove is provided on the inner surface of the support frame, and the slide groove is slidably connected to the limit block.

[0017] The beneficial effects of this application are:

[0018] (1) The welding fixture uses a limit assembly so that the worker needs to rotate the support frame. When the circuit board is turned over for welding, the worker pulls the pull rod to drive the sliding block to move the insertion rod out of the insertion hole on the outer wall of the support frame, thereby releasing the limit fixation of the support frame. After the support frame is turned over, the pull rod is released again. Under the reset action of the compression spring, the insertion rod is reinserted into the insertion hole on the outer wall of the support frame to complete the fixation of the support frame. The other side of the circuit board can be welded without fixing the circuit board, thereby improving work efficiency.

[0019] (2) The welding fixture can adjust the position of the support bar according to the different sizes of circuit boards by using the fixing component and the limiting component, and then fix the circuit boards of different sizes by moving the fixing component, thereby improving the application range of the device.
