Abstract
The utility model discloses an imaging device provided with a flexible circuit board, which comprises a CCD (Charge Coupled Device) and a quartz table for placing the flexile circuit board, and is characterized in that the CCD is arranged below the quartz table, and a light source is arranged at a position above the quartz table which is opposite to the CCD. The LED (light-emitting diode) light source emitting light downwards from above the flexible circuit board is arranged, so that the light can transmit the flexible circuit board and the quartz table to image directly so as to avoid influencing the imaging effect by reflection; and the intensity of the light source can be adjusted automatically, so that the imaging effect is better. The device is simple in structure, and is convenient and feasible.
Description
Technical field
The utility model relates to a kind of flexible circuit board imaging device.
Background technology
For welding chip on flexible circuit board accurately, all on the substrate of flexible circuit board, do the gauge point of a copper usually, be called MARK (mark), the telltale mark with this during as welding chip.During welding chip, at first need find the MARK of welding position on flexible circuit board, chips welding is carried out in the accurate position of determining by MARK then, and welding process is to carry out on the quartzy platform on the machine.Therefore, determine that accurately the position of MARK becomes the key of accurate welding chip.At present, the position of determining MARK is to realize by the flexible circuit board imaging device, existing flexible circuit board imaging device is the CCD (imageing sensor) that optical signalling can be converted to digital electric signal that establishes the band light source of a white and black displays below quartzy platform as shown in Figure 1.During work, light source is opened, and the quartzy platform that sees through the top is recorded as picture with the MARK on the flexible circuit board.Utilize light source to see through flexible circuit board when looking for MARK exactly, Tong Chu is different with the light source transmitance at no copper place establishing, and therefore can form the black and white contrast imaging, thereby determines MARK, finds the accurate welding position of flexible circuit board.
But there is following drawback in present flexible circuit board imaging device: flexible circuit board is above quartzy platform, the CCD automatic light source that is located at quartzy platform below must see through quartzy platform and shine on the flexible circuit board, with the MARK imaging, but for black-white CCD, because its light source that carries is strong inadequately, can cause the MARK contrast of imaging not enough; On the other hand, light source irradiation is on flexible circuit board the time, also can some be reflective, and therefore, cause image blur even can't discern, influence the accurate location of MARK, reduced work efficiency, influenced follow-up welding quality.
The utility model content
It is better that technical problem to be solved in the utility model provides a kind of imaging effect, can accurately locate the flexible circuit board imaging device of flexible circuit board MARK, simple in structure, easy to operate.
For solving the problems of the technologies described above, the utility model provides a kind of flexible circuit board imaging device, comprises CCD, is used to place the quartzy platform of flexible circuit board, it is characterized in that, described CCD is located at described quartzy platform below, with described CCD relative position place one light source is set above described quartzy platform.
Described light source is a led light source.
Described light source comprises the adjusting knob that can regulate the intensity of light source.
Described CCD is not for the CCD of light source.
The beneficial effect that the utility model reached: by a led light source that shines from the flexible circuit board top is set, make light pass flexible circuit board and quartzy platform downwards, reflective cause influence imaging effect is avoided in direct imaging; The intensity of light source can be regulated voluntarily, and imaging effect is better.Apparatus structure is simple, and is convenient feasible.
Description of drawings
Fig. 1 is existing flexible circuit board imaging device synoptic diagram;
Fig. 2 is a flexible circuit board imaging device synoptic diagram of the present utility model.
Among the figure, 1, quartzy platform; 2, CCD; 3, led light source; 4, flexible circuit board; 5, flexible circuit board support plate.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.Following examples only are used for technical scheme of the present invention more clearly is described, and can not limit protection scope of the present invention with this.
Fig. 2 be the utility model flexible circuit board imaging device preferred embodiment, place the flexible circuit board 4 that has flexible circuit board support plate 5 on the quartzy platform 1, quartzy platform 1 below is provided with CCD2, quartzy platform 1 top and CCD2 correspondence position are provided with led light source 3, the light that led light source 3 sends shines from the top down, pass flexible circuit board support plate 5 and shine on the flexible circuit board 4, CCD2 is with the imaging of MARK station acquisition, thereby weld the definite welding position of chip on flexible circuit board 4.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model know-why; can also make some improvement and distortion, these improvement and distortion also should be considered as protection domain of the present utility model.
