Description
Technical field
The present invention particularly drives about a kind of two-part relevant for a kind of PC board checking device, to reach the PC board checking device of accurate detection PC plate purpose.
Background technology
In the production line of electronic product, the detection of PC plate is an important and necessary operating process.After the circuit on the PC plate is finished layout, must detect the phenomenon whether each electrical contact on it has short circuit, confirm just can carry out next procedure after errorless.
Please refer to Fig. 1, is a known PC board checking device surface structure synoptic diagram.PC board checking device 1 among Fig. 1 comprises a pedestal 11, a base plate 12, a upper plate 13, a lower plate 14, reaches a mechanical arm group 15.Upper plate 13 also comprises four pilot holes 131 and a plurality of probe 132, and lower plate 14 comprises four reference columns 141 and a plurality of probe 142, and wherein the position of reference column 141 is corresponding mutually with pilot hole 131.Comprise lead that aforementioned probe is electrically connected in the pedestal 11 and in order to the control element of control mechanical arm group 15, general control element is a pneumatic cylinder, in order to the down pressing of further drive upper plate 13, the relevant electric lead of base interior system see through base plate 12 further with upper and lower plate in probe carry out electrically connect.
When a PC plate is desired to detect, at first should place on the lower plate 14 by PC plate to be measured, this moment, a plurality of probes 142 touched the specific electrical contact of this PC plate one side surface to be measured; Then see through control element control mechanical arm group 15, further upper plate 13 down is pressure bonded to four pilot holes, 131 covers should till four reference columns 141; A plurality of probes 131 on the upper plate 13 also touch the specific electrical contact on the opposite side surface of this PC plate to be measured at this moment, then again by operating personnel or relative program software interpretation test result.
Yet the position that aforesaid PC board checking device 1 is put PC version to be measured needs artificial the placement, and PC plate to be measured moves in the pressing process easily, and then causes erroneous judgement, makes the rate of resurveying higher.In addition, pulling at PC to be measured under the perfect state is that electrical contact with both sides contacts with the probe of upper and lower plates, and if the PC plate is subjected to displacement in the pressing process, very likely cause probe impaired in the pressing process, and the curved problem of plate appears in the PC plate, phenomenons such as part (as BGA, high-speed figure terminal ball grid array) solder crack on the further influence PC plate to be measured or empty weldering.
Summary of the invention
The object of the present invention is to provide a kind of PC board checking device, see through two-part and drive, to reach accurate detection PC plate purpose.
Based on above-mentioned purpose, the present invention discloses a kind of PC board checking device, comprises a base, a base plate, once pallet, a top board, a top tray and a two-part drive unit.
Plate upper surface comprises several first probes; Following pallet is coupled to the base plate top, and comprises several first perforations, its corresponding first probe.Top board is coupled to base, and the top board lower surface comprises a plurality of second probes; Top tray system is coupled to the top board below, and comprises several second perforations, its corresponding second probe.
The two-part drive unit is in order to after placing following pallet at a PC plate to be measured, elder generation's drive pressure is closed down and top tray, then drive pressing top board and base plate again, make first probe by first perforation contact PC plate lower surface, and second probe is by second perforation contact PC plate upper surface.
According to PC board checking device of the present invention, following pallet is preferable to see through the top that the first mechanical arm group is coupled to base plate, and the preferable second mechanical arm group that sees through of top board is coupled to base, and the preferable three-mechanical arm group that sees through of top tray is coupled to top board.The two-part drive unit is after a PC plate to be measured places following pallet, drive the second mechanical arm group earlier with pallet under the pressing and top tray, to finish the location of this PC plate to be measured, then drive the first mechanical arm group and three-mechanical arm group pressing top board and base plate again, make the lower surface of first probe, and second probe is by the upper surface of second perforation contact PC plate by first perforation contact PC plate.
Aforesaid two-part drive unit sees through a control module, carries out two-part and drives operation.The PC board checking device can be a full-automatic device, or the artificial manual drives operation of carrying out, and also can be semi-automatic driving operation.When the PC board checking device is a full-automatic device, its control module is the relay of a control internal circuit and the operating knob that starts this relay; And work as the PC board checking device is a manually driving operation, and its control module then can be a manually operated mechanical linkage.
The surface area of the preferable pallet down of the surface area of aforementioned top tray is little.General PC plate detects the electrical contact that all focuses on center section and detects, and the space that PC plate outer peripheral areas normally keeps, in order in back-end process, to weld or to connect other electronic components; Less with the area design of top tray can avoid being pressed onto these outer peripheral areas in the pressing process, also further avoid in the known technology because of the curved problem of the plate that pressing easily caused.
According to PC board checking device of the present invention, compared to known technology, advantage is that its PC plate can not be subjected to displacement in the pressing process, therefore can not cause probe impaired in the pressing process, and the curved problem of plate appears in the PC plate, more can not cause phenomenons such as part solder crack on the PC plate to be measured or empty weldering.
