As shown in fig. 1 ~ 3, an embodiment of a jig for soldering a PCB board includes:

spacing portion, spacing portion are used for fixing a position product 1, and the product 1 is injectd in vertical downwards and horizontal plane at least, and in this example, spacing portion is for seting up constant head tank 2 on base 4, and the bottom of constant head tank 2 holds in the palm product 1 and the shape of its bottom agrees with the shape of product 1 bottom, can be more stable hold product 1. The inner wall of the positioning groove 2 is matched with the bottom and the outer wall of the product 1 in shape. In other examples, the positioning grooves 2 may be replaced by other mechanisms such as clamping jaws or the like capable of fixing the product 1.

The vertical plate 3 is fixed on the base 4 and comprises two vertical pillars 301, and a rotating shaft 5 is connected between the two pillars 301.

The pressing member 6, pressing member 6 contains ferromagnetic metal, such as iron, nickel, cobalt, which can be attracted by a magnet. The pressing member 6 includes a pressing plate 601 and a control plate 602 which are integrally formed, and a plate surface of the pressing plate 601 and a plate surface of the control plate 602 are perpendicular to each other. The pressing plate 601 is fixed on the rotating shaft 5, and the control plate 602 just passes between the two pillars 301 when the pressing member 6 rotates along with the rotating shaft 5.

Height limit board 7, height limit board 7 are fixed on base 4 and are in between riser 3 and constant head tank 2, and height limit board 7's top is horizontal terminal surface 701, has seted up the recess on the horizontal terminal surface 701, imbeds first magnet 8 in the recess, and first magnet 8 flushes with horizontal terminal surface 701. The height of the height-limiting plate 7, the height of the rotating shaft 5, the height of the vertical plate 3 and the thickness of the pressing plate 601 are set to ensure that: when the pressing plate 601 is in a horizontal state, the pressing plate 601 is just pressed on the horizontal end face 701 of the height limiting plate 7, and at the moment, the pressing plate 601 is attracted by the first magnet 8 to press the PCB on the product 1. The side face, opposite to the vertical plate 3, of the height limiting plate 7 is a vertical plane 702, a groove is also formed in the vertical plane 702, the second magnet 9 is embedded into the second groove, and the visible part of the second magnet 9 is flush with the vertical plane 702; the control plate 602 is pushed towards the height limiting plate 7, the pressing plate 601 is enabled to rotate to be far away from the PCB, the free end of the control plate 602 is provided with a binding face, the binding face is a plane, the binding face is bound with the vertical plane 702 after the pressing piece 6 is far away from the PCB to a certain degree, and the binding face is just attracted by the second magnet 9, so that the distance between the pressing plate 601 and the PCB is kept, and a worker replaces the product 1 by a manipulator. In order to realize that the attachment surface is attached to the vertical plane 702, the inclination angle between the attachment surface and the surface of the control board 602 may be determined, and then the length of the control board 602 may be set according to the distance between the height-limiting plate and the vertical plate, the width of the pressing plate 601, and the distance between the rotating shaft 5 and the control board 602. In other examples, the ferromagnetic metal is intensively arranged on the pressure plate 601 at a position contacting with the first magnet 8, the ferromagnetic metal may not be included elsewhere, and the attraction force may be enhanced by replacing the ferromagnetic metal with the magnet. The control board 602 may have a ferromagnetic metal disposed at the abutting surface, or the ferromagnetic metal may be replaced by a magnet to enhance the attraction force.

The casting die 6 adopts metal material in order to guarantee the durability, and the PCB board is relatively fragile part after all, and casting die 6 direct action may cause the damage to it on the PCB board, so in this example, the free end of clamp plate 601 has L shape breach, is fixed with rubber pad 10 in the L shape breach, and rubber pad 10 has certain elasticity, suitably increases the thickness of rubber pad 10, makes it slightly outstanding for the face of clamp plate 601, not only can not damage the PCB board, can provide reliable pressure for the PCB board moreover.
