Detailed Description

To facilitate an understanding of the utility model, the utility model will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

As shown in fig. 1 and fig. 2, in a preferred embodiment, the fixture for forming a printed circuit board without positioning holes of the present invention mainly comprises a fixture body 1, wherein the fixture body 1 is made of metal or plastic, and is formed into a rectangle with four rounded corners, and the thickness is preferably 4mm to 6 mm. Being equipped with constant head tank 2 on the tool body 1, the overall dimension of constant head tank 2 and the circuit board main part phase-match of treating processing, it should be understood that, in order to improve the production efficiency and the reduction in production cost of circuit board, the circuit board main part is formed by a plurality of cell boards concatenation usually, can effectively fix the circuit board main part through constant head tank 2, avoids the circuit board main part to rock man-hour production. In this embodiment, the depth of the positioning groove 2 is preferably 2.5mm to match the thickness of most circuit boards on the market.

The both ends of the width direction of constant head tank 2 are equipped with respectively that first support is followed 3 and the second supports along 4, and first support is followed 3 and the second and is supported along 4 length direction extensions along tool plate body 1 for the flange edge of support circuit board main part. A plurality of supporting units 5 which are arranged in an array mode are arranged between the first supporting edge 3 and the second supporting edge, and the supporting units 5 are used for supporting and fixing the unit plates so as to guarantee the position accuracy of the unit plates.

The supporting unit 5 comprises a supporting plate 6, wherein the two sides of the supporting plate 6 in the width direction are provided with routing holes 7, and four corners of the supporting plate 6 are provided with positioning columns 9. Specifically, a plurality of reinforcing ribs 8 extending along the width direction of the positioning groove 2 are arranged in the positioning groove 2, the width between every two adjacent reinforcing ribs 8 is equal, the supporting plate 6 is arranged between every two adjacent reinforcing ribs 8, and the positioning columns 9 are arranged on two sides of the reinforcing ribs 8.
