Abstract
The utility model relates to a tension measuring fixture, which comprises a support, a rotary wheel connected to the top of the support via a bearing, double-sided adhesive arranged on the face of the rotary wheel, and an insulating base of a flexible printed circuit board, wherein the insulating base is adhered onto the double-sided adhesive. One end of a copper foil on the insulating base is connected with a sample clamp vertically above the rotary wheel, the bottom of the support is disposed at the fixed end of a tension unit, and the sample clamp is connected to an upper traction end of the tension unit. The tension measuring fixture is specially designed for stripping test of the flexible printed circuit board, a fixture for a rigid circuit board cannot be used for stripping due to flexibility of the flexible printed circuit board, the flexible printed circuit board can be adhered onto the rotary wheel with the double-sided adhesive according to the flexibility, the insulating base cannot be pulled when the copper foil is pulled by the sample clamp, as the rotary wheel is flexibly rotatable, a stripping point is positioned vertically above the rotary wheel and a 90-degree included angle can be maintained between the copper foil and the base, and thereby requirements of the test can be thoroughly met.
Description
Technical field
The utility model relates to a kind of tension measurement anchor clamps that are used for tensile test.
Background technology
Tension tester can carry out various stretchings, compression test, but for many special tests, can't obtain operable anchor clamps, need be according to the specific anchor clamps of situation design of test features and puller system.
When flexible printed wiring board is carried out disbonded test,, when peeling off, can not use the anchor clamps of existing rigidity wiring board owing to the flexibility of flexible printed wiring board.Be to lack corresponding tension measurement anchor clamps in the prior art.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of simple in structure, be applicable to the tension measurement anchor clamps that flexible printed wiring board carried out disbonded test.
For solving the problems of the technologies described above, the utility model provides a kind of tension measurement anchor clamps, and it comprises: support, bearing are connected in the rotor wheel of a top of the trellis, the insulating substrate of being located at the double faced adhesive tape on the rotor wheel wheel face and being bonded in the flexible printed wiring board on this double faced adhesive tape; The specimen holder that one end and of the Copper Foil on the insulating substrate is in directly over the rotor wheel links to each other; The stiff end of puller system is located in the bottom of support, and specimen holder is connected the last tractive end of puller system.
Good effect of the present utility model: tension measurement anchor clamps of the present utility model are specially for flexible printed wiring board carries out disbonded test design, because the flexibility of flexible printed wiring board, can not use the anchor clamps of rigidity wiring board when peeling off.Flexibility according to it can be bonded in it on the rotor wheel with double faced adhesive tape, when specimen holder pulling Copper Foil, insulating substrate can not be pulled up, and owing to rotor wheel can rotate flexibly, directly over making that burble point is positioned at, make Copper Foil and base material can keep 90 ° angle, can satisfy the requirement of test so fully.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, below the specific embodiment and in conjunction with the accompanying drawings of basis, the utility model is described in further detail, wherein
Fig. 1 is the structural representation of the tension measurement anchor clamps among the embodiment.
Embodiment
See Fig. 1, the tension measurement anchor clamps of present embodiment comprise: support 1, bearing are connected in the rotor wheel 2 at support 1 top, the insulating substrate 3 of being located at the double faced adhesive tape on rotor wheel 2 wheel faces and being bonded in the flexible printed wiring board on this double faced adhesive tape; The specimen holder 5 that one end and of the Copper Foil 4 on the insulating substrate 3 is in directly over the rotor wheel 2 links to each other.
The stiff end 6 of puller system is located in the bottom of support 1, and specimen holder 5 is connected the last tractive end 7 of puller system.
During work, last tractive end 7 drives upwards tractive Copper Foil 4 of specimen holder 5, insulating substrate 3 can not be pulled up under the effect of double faced adhesive tape, and rotor wheel 2 can rotate flexibly simultaneously, make the burble point of insulating substrate 3 and Copper Foil 4 be positioned at rotor wheel 2 directly over, make Copper Foil 4 and insulating substrate 3 can keep 90 ° angle, can satisfy the requirement of test so fully.
The foregoing description only is for the utility model example clearly is described, and is not to be qualification to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all embodiments.
