The specific implementation mode is as follows:
the technical idea of the application is that a detachable tray is arranged on a test tool to realize rapid up-and-down of a piece to be tested; through the probe on the floating plate cooperation fixed support plate and to and the structure comprehensive characteristics of tray, realize the accurate location of the piece that awaits measuring, promote the measuring accuracy.
The present application is illustrated with the scheme shown in fig. 1 as example 1:
as shown in the figure, the structure of the application comprises a tray 1 and a floating plate 2; the floating plate is supported by the elastic piece and floats on the carrier plate 3; the carrier plate is a component connected with the module testing tool, and a probe used for being in contact with the module contact is arranged on the carrier plate.
The detachable tray is arranged in a positioning groove 21 on the floating plate; the bottom of the positioning groove is hollowed out, and the positioning groove has the function that the probe penetrates out from the lower part to contact the module contact on the tray.
Be provided with the module standing groove on the tray, its shape and size conform to with the module, are used for fixing a position the module. Usually, a plurality of modules, in this embodiment, 10pin modules, are placed in one module placing slot.
The floating plate is supported on the carrier plate through the guide posts 4 at four corners and the springs and can move up and down. The floating plate is used for being matched with a pressing plate of the test tool. During testing, the tray loaded with the piece to be tested 5 is placed on the floating plate, the pressing plate is pressed downwards to enable the tray and the floating plate to sink, and the probes on the carrier plate oppositely penetrate out from the lower part and contact the contacts of the piece to be tested to conduct testing.
Furthermore, the hollow-out of the bottom of the positioning groove of the floating plate is a long groove-shaped through hole. In this embodiment, put 10pin modules in every module standing groove, every module both ends respectively need two probes, then 10pin modules need two rows, and every row 20 probes test. The slot-shaped through hole has the function of enabling a row of probes to penetrate out of the slot-shaped through hole. In this embodiment, 3 module placing grooves are arranged on the tray, and 6 long groove-shaped through holes are correspondingly formed in the tray.
The positioning groove is a sinking groove with an opening at the front end; chamfers are arranged on two sides of the opening at the front end of the positioning groove, so that the opening end is trumpet-shaped. The position of the lateral wall location horizontal direction of tray through the constant head tank, the probe of being convenient for accurately contacts with the contact, and loudspeaker form opening plays the guide effect for installing the tray, has the clamp plate because of the top, so the tray generally inserts in the test fixture from the place ahead. The front end of the tray is provided with a handle to avoid hand sliding, and the tray is convenient to take and place.
For sinking or fretwork in the middle of the module standing groove on the tray for give the part of moulding plastics on the module and give way the space, both sides respectively have one row of probe hole, are every row of 20 holes in this embodiment. The position of the probe hole corresponds to the contact of the bridge wire end/foot wire end of the module. When the tray is arranged in the positioning groove, the probe hole corresponds to the long groove-shaped through hole at the bottom of the positioning groove.
And a plurality of groups of module placing grooves are arranged on the tray. In this embodiment, each tray is provided with 3 module placing grooves, and 3 10pin modules can be placed and tested simultaneously. The standing groove is transversely arranged.
The structure shown in fig. 6 is taken as an embodiment 2 to explain a technical scheme of a module testing tool:
as shown in the figure, the quick change device of embodiment 1 is included in this embodiment, and a base 6 is further included below the carrier plate. The base is provided with a probe 8 and a data interface connected with the probe;
be provided with the clamp plate in the top of kickboard, vertical motion about guiding mechanism can be followed to the clamp plate, and the elbow that the clamp plate passes through the top presss from both sides the drive and can lock and die, and in fact, only need make the clamp plate can remove and lock the function that can realize this application, and a lot of current structures can all be used to this application, no longer give unnecessary details here.
The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
