Description

A kind of pcb board multiple-station rotation detection device
Technical field
The utility model belongs to a kind of pcb board multiple-station rotation detection device.
Background technique
After producing pcb board, generally requires and pcb board is tested.For example, whether route connects, short circuit, disconnects, Whether each pin is connected, to judge whether pcb board produced meets product requirement and technical standard.
And current detection device is having the disadvantage that in use
First, current detection device can only realize that single product detects, and clamping and detection cannot carry out simultaneously, there is effect Rate is low, and detection cycle is long, is unfavorable for saving time and batch detection;
Second, current detection can only realize that single module detects, and for complicated pcb board, since there are multiple functions Module needs to be placed on different detection devices, is unable to fixed-point operation, and detection process is very troublesome.
Utility model content
In order to which in view of the one or more defects existed in the prior art in above-mentioned, the utility model provides a kind of PCB Plate multi-station rotary sensing device.
To achieve the above object, the utility model provides a kind of pcb board multiple-station rotation detection device, and feature exists In: including rack (1), turntable (2), protractor (3), decelerating motor (4), multiple pcb board detection stations (5);Turntable (2) water Above rack (1), which is rotatablely connected prosposition by shaft (6) and the rack (1), and the decelerating motor (4) is defeated Outlet is connect by the protractor (3) with the shaft (6) lower end;Each pcb board detection station (5) is mounted on turntable (2) it is circumferentially uniformly distributed on and along the turntable (2);The pcb board detection station (5) includes bakelite box (5-1), bracket (5- 2), support plate (5-3), pressure bar plate (5-4), pressure bar (5-5), lifting seat (5-6), cylinder (5-7) and vertical guide rod (5-8), the electricity Wooden box (5-1) is fixed on the turntable (2), and the bracket (5-2) and support plate (5-3) are each attached on bakelite box (5-1), The lifting seat (5-6) is slidably connected by vertical guide rod (5-8) with the bracket (5-2), cylinder (5-7) output end and this Lifting seat (5-6) connects and for driving the lifting seat (5-6) to go up and down, which is located at the support plate (5-3) Surface and detachable affixed with the lifting seat (5-6), is fixedly installed one or more on the downside pressure bar plate (5-4) The pressure bar (5-5).
Using the above scheme, which can be made by protractor (3) driving turntable (2) intermittently indexing rotation It the operating position of each pcb board detection station (5) can be in rotational direction by successively alternately simultaneously station changes.Pcb board detection The support plate (5-3) of station (5) is for carrying pcb board to be measured, and the pressure bar plate (5-4) and the pressure bar (5-5) are detection module, It is that integral replacing is done when test object difference according to corresponding pcb board matching setting to be measured.Wherein the pcb board detects work When the detection of position (5), which is placed on support plate (5-3), is restarted the cylinder (5-7), is driven the lifting seat (5-6) vertically guide rod (5-8) is oriented to downward movement, and synchronous drive pressure bar plate (5-4) and thereon under each pressure bar (5-5) Row movement, finally side pressure touches the pcb board to be measured and realizes detection under each pressure bar (5-5).
