Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

The embodiment discloses a flexible printed circuit board (FPC) fixing tool, which comprises a box body 1, an air pipe 2 and a vacuum pump, wherein a cavity is formed inside the box body 1, an opening is formed at the upper end of the box body 1, and the cavity in the box body 1 is communicated with the outside; meanwhile, the upper end of the box body 1 is also provided with a groove 3 around the opening on the box body 1, and a tooling plate 4 is embedded in the groove 3; the tool plate 4 is embedded into the groove 3, so that the cavity can be sealed; the tool plate 4 is provided with a plurality of through holes 5 communicated with the cavity; the box body 1 is further provided with a vent hole 6, one end of the air pipe 2 is hermetically connected with the vent hole 6, and the other end of the air pipe 2 is connected with a vacuum pump. The tooling plate 4 is embedded into the groove 3 on the box body 1 and sealed to cover the cavity, and the FPC soft board 10 is placed on the tooling plate 4 and sealed to cover the through hole 5 on the tooling plate 4; the vacuum pump is opened, air in the cavity is pumped out through the air pipe 2, then a certain vacuum degree is formed in the cavity of the box body 1, negative pressure is generated, under the action of the negative pressure, the FPC hose is tightly attached to the tooling plate 4 and blocks the through hole 5, and then the FPC soft board 10 is attached to and positioned on the tooling plate 4 all the time. The tool is simple in structure, enables the FPC soft board 10 to be positioned more simply and rapidly, does not need to be in direct contact with the FPC soft board 10 through a press fitting machine, and can play a good role in protecting the FPC soft board 10. The through hole 5 in the tooling plate 4 is not likely to have an excessively large diameter, and preferably, the diameter of the through hole 5 is 1 to 2 mm. Therefore, when the aperture of the through hole 5 is large, the FPC soft board 10 can be prevented from sinking along the through hole 5 to the inner cavity direction of the box body 1 to damage the through hole.

In the above-described embodiment, preferably, the bottom center portion of the case 1 is provided with a vent hole 6. Therefore, stress on each part of the FPC soft board 10 is more uniform, and deformation of the FPC soft board 10 due to nonuniform stress is avoided. Furthermore, the through holes 5 are uniformly distributed on the tooling plate 4 in a matrix form, so that each part of the FPC soft board 10 can be uniformly stressed. Meanwhile, a sealing ring 7 is fixed at the bottom of the tooling plate 4, and after the tooling plate 4 is embedded into the groove 3, the sealing ring 7 is abutted against the bottom of the groove 3; therefore, the tightness between the tooling plate 4 and the box body 1 can be increased, and the fixing and the positioning of the FPC soft board 10 are prevented from being influenced by air leakage.

In addition, an opening is formed on one side of the groove 3, and a handle is arranged on one side, corresponding to the opening, of the tooling plate 4. So, conveniently dismantle frock board 4 or install in recess 3 on box 1. The edge of the tooling plate 4 is also provided with a frame 8 which is arranged around the tooling plate 4 and is used for supporting and protecting the tooling plate 4; meanwhile, the middle part of the lower end of the frame 8 is also fixed with a beam 9 for supporting the tooling plate 4. Thus, the overall strength of the frame 8 can be increased, and the frame can be better used for supporting the tooling plate 4.

In the present invention, it should be understood that the terms "upper" and "lower" indicate the orientation or the position relationship based on the orientation or the position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and therefore, the present invention is not limited thereto.
