The present invention will be described in detail with reference to the accompanying drawings 1 to 9 and examples.

Referring to fig. 1 to 9, the present embodiment provides an adjustable detection fixture for performing thickness detection on a reinforcing sheet 7 on an FPC6, including:

the device comprises a bottom plate 1 and guide plates 2, wherein a group of guide plates 2 capable of accommodating an FPC6 are arranged on the upper surface of the bottom plate 1;

the detection board 3 is arranged on the bottom plate 1, one ends of the two guide plates 2 are abutted to the detection board 3, and a detection channel for the FPC6 to pass through is formed between the detection board 3 and the bottom plate 1;

the detection device comprises a detection plate 3, and is characterized in that a mounting seat is arranged in the detection plate 3, a plurality of adjusting components 4 can be placed on the mounting seat, each adjusting component 4 comprises a bolt 41, a rod part and at least one adjusting gasket 44, two ends of each rod part penetrate through the mounting hole, the adjusting gaskets 44 are sleeved on the outer walls of the rod parts, the adjusting gaskets 44 are clamped between the top ends of the rod parts and the mounting holes, the height of each adjusting gasket 44 can be adjusted to the height of a detection channel, and the bolts 41 are connected with the mounting seat. The bolt 41 may be a socket head cap screw, which is a screw for fixing the relative position of the parts, and may be classified according to the groove type, and may be a socket head angle set screw, a socket head set screw, a straight groove set screw, a square head set screw without a groove type, and the like. The positioning pin of the stop screw has the same function, is generally used for connecting two parts to play a role in fixing, and the screw can be integrally screwed in, so that the appearance is smooth and attractive. When using the set screw, the screw is first screwed into the internally threaded hole of the part to be fixed and then the end of the screw is pressed against the surface of the other part (or a corresponding recess in the surface), even if the relative positions of the two parts are fixed.

Specifically, referring to fig. 5, in the present embodiment, the shaft includes a top 42 and a shaft 43, and a diameter of the top 42 is larger than a diameter of the shaft 43.

Specifically, referring to fig. 6, in the present embodiment, the mounting seat is provided with a first mounting hole 31 corresponding to the top portion 42 and a second mounting hole 32 corresponding to the rod body 43, and the first mounting hole 31 and the second mounting hole 32 form a step-shaped structure. The adjusting shim 44 is disposed in a space formed below the top portion 42 and the first mounting hole 31. The adjusting washer 44 has a diameter smaller than the diameter of the first mounting hole 31 and larger than the diameter of the second mounting hole 32. The adjusting gaskets 44 can be installed in a stacked mode, height adjustment of the detection channels is achieved through the adjusting gaskets 44 with different quantities, and qualified detection can be conducted according to different thicknesses of actual products.

Specifically, in this embodiment, two ends of the rod 43 penetrate through the second mounting hole 32.

Specifically, in this embodiment, the number of the adjusting assemblies 4 is at least one, and the adjusting assemblies 4 can be installed for product detection according to actual product detection requirements.

Specifically, in this embodiment, the height of the detection channel ranges from 0.1mm to 0.5mm. According to the actual thickness of the product, the height dimension of the detection channel can be adjusted by replacing the number of the adjusting gaskets 44 with corresponding precision.

When the jig detects the FPC6, the FPC6 slides on the surface of the base plate 1 along the guide plate 2 and passes through the detection channel, a detection position is formed between the bottom of the rod body 43 and the base plate, and the reinforcing sheets 7 with different thicknesses slide along the corresponding detection positions. Specifically, if the thickness of one of the reinforcing sheets 7 is too thick, the reinforcing sheet 7 causes the FPC6 not to pass through the detection channel smoothly, and thus, it is determined that the FPC6 is not qualified; on the contrary, if the FPC6 slides smoothly through the detection passage, the thickness of the reinforcing sheet 7 in a plurality of areas on the FPC6 is acceptable.

By means of the structure, the distance between the bottom of the rod body 43 and the bottom plate 1 is the height of the detection channel, and whether the reinforcing sheet on the FPC is attached again or not is detected by adjusting the quantity of the gaskets 44 and the height of the detection channel; referring to fig. 7 and 8, if the reinforcing sheet 7 on the FPC6 can pass through the detection channel smoothly, it is described that the reinforcing sheet 7 is normally attached and is in a qualified state; if the reinforcing sheet on the FPC is clamped by the bottom of the rod body 43, the thickness of the reinforcing sheet 7 cannot normally pass through the detection channel, and then the product is repeatedly attached and is regarded as a defective product. The height of the original detection jig mentioned in the background art is adjusted if needed, the height of the jig is increased by additionally installing a gap piece, or the height is reduced by adopting a grinding jig, the adjustment height can only be maintained by returning to the factory, the detection cost is increased, the adjustment assembly in the embodiment adjusts the detection height needed by an actual product by using an adjusting gasket, the repair cost of the detection jig can be reduced, the detection cost is reduced, the working time is reduced, the working efficiency is effectively improved, the original detection jig can only correspond to the product detection of one height, the adjustable detection jig in the embodiment can flexibly adjust the height of a detection channel, the multiple products can be flexibly adjusted to share one detection jig, and the development cost of the detection mold is reduced.
