Utility model content
Problem to be solved in the utility model is to provide a kind of test charging tray positioning device, and structure is simple, and registration is high, and greatly reduce manual operation error, operating efficiency significantly improves.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of test charging tray positioning device, comprises workbench; Described workbench is provided with the charging tray station of several rectangle; On workbench, corresponding each described charging tray station is provided with monitoring unit; A pair adjacent side of each described charging tray station is respectively arranged with one group of alignment pin, its another to adjacent side being arranged respectively one group of spring leaf.
Further, described charging tray station is 3 that are arranged side by side successively.
Further, described monitoring unit comprises horizon sensor, alarm and indicator light.
Further, described alignment pin comprise shank and be threaded in shank lower end tighten screw.
Further, described shank upper end is cone end.
Further, described often group alignment pin is 2.
Further, described spring leaf, in " L " type structure, comprises level fixed installation transverse sheet on the table and the vertical sheet be vertically connected on transverse sheet; Described transverse sheet is provided with fixing hole.
Further, described vertical sheet upper end is with towards the bending outside charging tray station.
Further, described often group spring leaf is 2.
The advantage that the utility model has and good effect are:
1) utilize the elastic force of spring to be against on alignment pin by charging tray, repeatable accuracy is high.
2) structure is simple, be adapted at compact Test handler in use.
3) only need shirtsleeve operation just can complete the replacing of Tray, under the prerequisite ensureing positioning precision, decrease the downtime of machine.
4) monitoring unit be provided with can monitor the frequency that Tray dish is changed, and whether the placement of Tray dish meets the requirements, and further increases stability and the reliability of whole Test handler.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of spring leaf in the utility model;
Fig. 3 is the structural representation of alignment pin in the utility model.
Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
A kind of test charging tray positioning device, as shown in Figure 1, comprises workbench 1; Workbench 1 is provided with the charging tray station 2 of several rectangle; On workbench 1, corresponding each described charging tray station 2 is provided with monitoring unit 4; A pair adjacent side of each described charging tray station 2 arranges one group of alignment pin 5 respectively, its another to adjacent side being arranged respectively one group of spring leaf 3.
It should be noted that, described charging tray station 2 matches with the Tray dish meeting JEDEC standard, can be have the concave station matched with Tray dish lower end, when placing charging tray, further defining charging tray position, locating more convenient.In addition, corner, workbench 1 lower end is provided with the pillar 6 of adjustment height, according to adjusting workbench 1 height easily, and by the adjustment to pillar 6, can ensure that workbench 1 is in the state of complete level.
Wherein, described charging tray station 2 is 3 that are arranged side by side successively, and once can place more product test, production efficiency is high.
Wherein, described monitoring unit 4 comprises horizon sensor, alarm and indicator light, can also arrange distance sensing device.
Wherein, as shown in Figure 3, what described alignment pin 5 comprised shank 51 and was threaded in shank 51 lower end tightens screw 52.It should be noted that, workbench 1 is reserved with the installing hole installing alignment pin 5, during installation, shank 51 is in workbench 1 upper surface, screw 52 will be tightened penetrate installing hole from workbench 1 lower surface and be threaded in shank 51, and tighten, shank 51 can be fixed.
Wherein, described shank 51 upper end is cone end 53.It should be noted that, scratch for preventing from producing operating personnel or product to be measured, the cone end 53 on alignment pin 5 shank 51 top has cut away the part at vertex of a cone tip, and upper surface and adjacent conical surface rounding off.
Wherein, described often group alignment pin 5 is 2, determines straight line at 2, one end of charging tray can be positioned on a limit of charging tray station 2 completely.
Wherein, as shown in Figure 2, described spring leaf 3, in " L " type structure, comprises the vertical sheet 32 that level is fixedly mounted on the transverse sheet 31 on workbench 1 and is vertically connected on transverse sheet 31; Described transverse sheet 31 is provided with fixing hole 33.It should be noted that, fixing hole 33 is two.By the screw being screwed into fixing hole 33, transverse sheet 31 is pressed on workbench 1, guarantees fixed.
Wherein, described vertical sheet 32 upper end is with towards the bending 34 outside charging tray station 2, and when placing charging tray, guide effect is played in bending 34, makes charging tray be pressed down into position smoothly.
Wherein, described often group spring leaf 3 is 2, determines straight line at 2, one end of charging tray can be positioned on a limit of charging tray station 2 completely.
When charging tray installs location, Tray dish only need be aligned charging tray station by operator, makes charging tray X, Y both sides prop up alignment pin 5, then downward compacting charging tray, and now, the spring leaf corresponding with X, Y-direction alignment pin 5 pushes down charging tray to each self-corresponding alignment pin 5 direction.It should be noted that, even if during initial placement charging tray, charging tray does not first prop up alignment pin 5, and so spring leaf also can push charging tray to the alignment pin 5 of its correspondence automatically, and pushes down closely, like this, ensure that the repeatable accuracy of each discharge plate completely.In addition, whether each sensor scan Tray dish in the monitoring unit arranged is installed in place, if Tray dish is not put well or Tray tilts, so alarm will send warning, and have warning lamp to light, so just further ensure that the repetition installation accuracy of charging tray.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
