Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

Fig. 1 is the structural schematic diagram of the present invention, fig. 2 is the structural schematic diagram of the PCB positioning plate of the present invention, and fig. 3 is the structural schematic diagram of the female carrier of the present invention.

The utility model provides a PCB board automated inspection tool, keeps away position groove 6 and constant head tank 7 including detecting faller 1, female microscope carrier 2, support stick 3, PCB locating plate 4, wire rod box 5, wire rod, detect faller 1 and pass through the guide arm sliding fit and connect on female microscope carrier 2, seted up the fluting on female microscope carrier 2, the fluting internal fixation of female microscope carrier 2 has more than one support stick 3, is fixed with PCB locating plate 4 and wire rod box 5 on female microscope carrier 2, and PCB locating plate 4 has seted up wire rod with wire rod box 5 adjacent one side and has kept away position groove 6, and wire rod keeps away position groove 6 and the trompil of wire rod box 5 curb plate and be linked together, has seted up constant head tank 7 on PCB locating plate 4. Foam for supporting the PCB is fixed in the slot of the mother carrying platform 2. A rod body is fixed on the PCB positioning plate 4, the rod body penetrates through the pressing block 8, and a spring is connected between the pressing block 8 and the rod body.

Referring to fig. 1, 2 and 3, the detection needle plate 1 is composed of a connecting plate and a probe, the probe is electrically connected with a detection device through an adapter, the probe is fixed on the connecting plate, the connecting plate is fixed at the moving end of an air cylinder or an electric cylinder to move up and down, and the probe is used for detecting a PCB. The probe can rapidly test and detect the abnormal states of short circuit, open circuit, wrong parts, missing parts, component value change and the like of the PCB and the components on the PCB through the input micro current.

Firstly, the PCB is placed in a positioning groove 7 of a PCB positioning plate 4, components on the PCB penetrate through the positioning groove 7, a supporting rod 3 in a groove of a female carrier 2 supports the bottom surface of the whole PCB, and wires connected on the PCB are in a wire avoiding groove 6 and enter a wire box 5 from an opening on the side wall of the wire box 5. Thus, when the detection needle plate 1 is pressed down, the wire can not be touched. And because the support of the support rod 3, the components on the PCB can not be directly stressed by contacting with the mother carrier, and the damage can be avoided. The foam can be used as a support for the PCB bottom surface element device, and the foam is elastic, so that the element device cannot be strongly extruded.

And briquetting 8 then can slide from top to bottom and rotate along the body of rod on PCB locating plate 4, and briquetting 8's pressure head is rotatory backward and breaks away from the top of constant head tank 7, can let the PCB board place in the constant head tank 7 like this, after putting, moves briquetting 8 up again and selects to PCB board top, releases briquetting 8, and briquetting 8 is driven down the removal at the spring rebound to with PCB board centre gripping on PCB locating plate 4.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
