Embodiment 1

[0033] ReferFigure 1-7 One planar flying needle test device includes a gantry 1 and a machining chamber 2 mounted thereon, and the front end of the processing chamber 2 is fixed having a baffle 3, and two cylinders 4, two cylinders are fixed. The end of the fourth pressure plate 5 is fixed, and the bottom portion of the lower pressure plate 5 is fixed, and both sides of the separator 6 are provided with a positioning mechanism, and the upper end of the gantry 1 is fixed with two upper motors 25, two The output shaft of the upper motor 25 is fixed to the upper wire 26, and the side walls of the two upper filament rods 26 are commonly threaded and connected to the binder 27, and the cartridge 27 is provided with an automatic clamping mechanism.

[0034] The positioning mechanism includes a lateral motor 7 fixed to the bottom of the lower pressure plate 5, and the output shaft of the transverse motor 7 is fixed to the lateral sidewall 8, and the lateral slider 9 is connected to the l...

Embodiment 2

[0044] Refer Figure 8 The difference from the first embodiment is that the buffer mechanism is different, the buffer mechanism includes a separation ring 58 fixed to the inner wall of the buffer 25, and the upper end of the sound ring 58 is opened, and the inner wall sealing of the expansion tank 59 is slid. The top ring 60, the upper end of the top ring 60 fixedly having a plate 56, and the upper end of the plate 56 is co-fixed with the top of the buffer barrel 24, and the bottom portion of the plate 56 is fixed, and the bottom fixing of the link 55 is fixed. There is a probe 48 through the bottom of the buffer cartridge 24, and the internal filling of the expansion tank 59 is filled with a current variable.

[0045] At the time of actual processing, the activation of the cylinder 4 will cause the current soot fluid in the inside of the expansion tank 59 to be electrically powered, and therefore, the current solenoid is expanded and restored, so that the top ring 60 can be pushed...

Embodiment 3

[0047] Refer Figure 9 The difference between the embodiment and the first embodiment is that the angular adjustment mechanism is different, and the angle adjustment mechanism includes the electromagnetic coil 51 and the separator 52 fixed to the inner wall of the propulsion box 41, and the upper end of the separator 52 runs through the sliding bar 54, inserted The sidewalls of the rod 54 are commonly connected to the separator 52, and the inner wall blocking the inner wall of the propulsion box 41 is slidably linked. The upper portion of the propulsion box 41 is filled with a current variable fluid, and the inner wall of the angle box 23 is open. The angle slot 49, both sides of the biased plate 39, respectively, by two equilibrium spring 50, respectively, inner walls of the two angular grooves 49;

[0048] At the time of processing, if the angle of the probe 48 is required, increase the power of the electromagnetic coil 51, control its magnetic field strength size, and control it...

Abstract

A planar flying probe testing device disclosed by the invention comprises a rack and a processing chamber installed on the rack. The front end of the processing chamber is fixedly provided with a baffle plate, the top of the processing chamber is fixedly provided with two cylinders, the end parts of the two cylinders are jointly fixedly provided with a lower pressing plate, the bottom of the lower pressing plate is fixedly provided with a partition plate, positioning mechanisms are arranged on the two sides of the partition plate, two feeding motors are fixed to the upper end of the rack, feeding lead screws are fixed to output shafts of the two feeding motors, and the side walls of the two feeding lead screws are jointly in threaded connection with a material box. The device has the advantages that the electromagnet and the capacitor are arranged, when each cylinder is started, the capacitor is charged at the machining moment, charging is rapidly completed, then power is cut off, and discharging is performed outwards so that when the cylinder drives the whole to press downwards, the probe temporarily shrinks, instant extrusion collision is avoided, and the probe slightly and slowly moves downwards to make contact with a plate after short time delay; and the impact on the plate can be reduced, and tin soldering on the surface of the plate is not damaged.

Description

Technical field [0001] The present invention relates to the field of flying needle test, and more particularly to a planar flying needle test device. Background technique [0002] The flying needle tests it uses a probe to replace the needle bed, using multiple motor-driven, able to quickly move the electrical probe pin to contact and conduct electrical measurement, is the latest solution for some major problems of electrical testing . [0003] The displacement position in the conventional flying needle test machine is achieved by the basic single screw mechanism, which is limited to the guides of the screw, etc., so that the overall positioning accuracy and positioning speed cannot be satisfied simultaneously, so the processing is increasing fulfil requirements, [0004] And the existing test probe is physically in contact with the welding of the through hole and the test pad, which will leave a small pit on the solder; for some products, these small pits may be considered a def...
