Description

  The present invention relates to a circuit board test system, a circuit board test method, and a circuit board mounting apparatus.

  In order to check the conductive state of a circuit on a printed circuit board (abbreviated as a circuit board), it is common to use a test device to perform a test by contacting the inspection probe with a contact on the printed board. During the test, the circuit board may be fixed to a stage inside the test apparatus. The inspection probe then extends downward to the circuit board and contacts the circuit board contacts, thereby checking for electrical conductivity.

For example, when the flexible circuit board is inspected, drooping due to gravity may occur in the central portion of the flexible circuit board, which makes it impossible to keep the flat state for a long time. For this reason, when such a flexible circuit board is inspected by the test apparatus, the inspection probe may not reliably contact the contact of the flexible circuit board. As a result, when a precise inspection probe having high positioning accuracy is arranged in the test apparatus, this precise inspection probe is likely to be broken beyond its actual tolerance value depending on the degree of distortion or deformation of the flexible circuit board.

  Please refer to FIG. 8, FIG. 9A and FIG. 10A together. The fixing member 162a3 includes a fixing block 162a31 and a roller 162a32. The fixed block 162a31 is connected to the second end 162a22. The roller 162a32 is pivotally attached to the fixed block 162a31, and is arranged so as to press the corresponding clamping head 132c. As a result, even if the elevating bottom plate 132d moves along the first direction A1 according to the interlocking plate 132b23 within the period in which the roller 162a32 presses the elevating bottom plate 132d, the roller 162a32 is caused to have a frictional force with the elevating bottom plate 132d. Can be removed.

  According to the above-described structure arrangement, when the circuit board is to be mounted, the lock release structure 162 releases the lock on the holding structure 132, and the holding head 132c is separated from the holding bottom plate 132b25. Specifically, the cylinder module 163 can be driven to extend the cylinder rod 163a and move it to the clamping structure 132, and the pressing assembly 162a presses the clamping head 132c (presses the lifting bottom plate 132d). The first pressing block 162b presses the first displacement substrate 132b1 and moves in the first direction A1 against the first base 131 by moving the holding head 132c away from the holding bottom plate 132b25. The second pressing block 162c presses the second displacement substrate 132b2 and moves inward along the second direction A2 with respect to the first base 131. Then, the third pressing block 162d presses the interlocking plate 132b23 so as to be opposed to the first base 131. When interlocked to move outwards Te along the first direction A1, a clamping structure 132 can be in the unlocked state as shown in FIGS. 10A and 10B. In this case, the user can sandwich a part of the circuit board between the sandwiching head 132c and the sandwiching bottom plate 132b25.

  Next, the pressing assembly 162a, the first pressing block 162b, the second pressing block 162c, and the second pressing block 162c are driven within the period in which the cylinder module 163 drives the cylinder rod 163a to return and move away from the clamping structure 132. By setting the third pressing block 162d to an appropriate length, the third pressing block 162d is first released from the interlocking plate 132b23, and then the pressing assembly 162a is released from the elevating bottom plate 132d to hold the clamping head 132c. When the first pressing block 162b and the second pressing block 162c are separated from the first displacement substrate 132b1 and the second displacement substrate 132b2, respectively, the sandwiching structure 132 is shown in FIG. 9A and 9B are held. Door can be.

  Specifically, the third pressing block 162d is first separated from the interlocking plate 132b23 within a period in which the cylinder rod 163a is driven by the cylinder module 163 to move back and move away from the holding structure 132. The interlocking plate 132b23 is moved inward along the first direction A1 with respect to the first base 131, and the clamping head 132c is further moved to a position approaching the center of the first base 131. In order for the roller 162a32 to continuously press the elevating bottom plate 132d by the spring 162a4 provided between the movable substrate 162a1 and the fixed member 162a3, the third pressing block 162d has a time for the holding head 132c to further descend. It can be delayed after being detached from the interlocking plate 132b23. When the sandwiching head 132c is lowered so that the circuit board is sandwiched by the sandwiching bottom plate 132b25, the first pressing block 162b and the second pressing block 162c are respectively moved to the first displacement substrate 132b1 by the cylinder rod 163a that is continuously lowered. Then, the first displacement substrate 132b1 and the second displacement substrate 132b2 are moved outward with respect to the first base 131. In this case, since the clamping head 132c that sandwiches the circuit board also moves outward with respect to the first base 131, the circuit board can be unfolded and the circuit board can be held in a flat state, thereby improving the test accuracy. Can do.

  According to the embodiment, since the circuit board mounting apparatus completes the mounting and unlocking of the circuit board by a simple mechanical method, complicated wiring can be omitted, and the circuit board according to the embodiment It will be appreciated that it can be used in conjunction with test system 100 and circuit board test methods.

  In some embodiments, the clamping structure 132 is abbreviated to the displacement assembly 132b, and the corresponding unlocking structure 162 is abbreviated to the first pressing block 162b and the second pressing block 162c, and roughly the embodiment. Based on this principle, the unlocking and clamping process may be performed. Such a clamping structure 132 does not mainly unfold the circuit board during clamping of the circuit board, for example, like the lower left clamping structure 132 in FIG. Other details of such a clamping structure 132 and the corresponding unlocking structure 162 will not be described in detail here.

  In some embodiments, the clamping structure 132 may align the first displacement substrate 132b1 and the second displacement substrate 132b2 in the displacement assembly 132b to a single displacement substrate. The corresponding unlocking structure 162 abbreviates the second pressing block 162c, and may perform the unlocking and clamping process based on the principle of the above-mentioned embodiment. Such a clamping structure 132 allows the circuit board to be developed in only one direction while the circuit board is being clamped. For example, the upper left clamping structure 132 in FIG. 5 allows the circuit board to be developed along the first direction A1. The lower right holding structure 132 in 5 expands the circuit board along the second direction A2. Other details of such a clamping structure 132 and the corresponding unlocking structure 162 will not be described in detail here.
