Description

Floating clamping jaw and test system for memory bank test

Technical Field

The utility model belongs to the technical field of memory strip testing, and particularly relates to a floating clamping jaw and a testing system for memory strip testing.

Background

In the automatic memory bar test line, the memory bar clamping jaw is a device directly contacting the memory bar. The plugging accuracy of the clamping jaw and the fact that the clamping jaw cannot damage the memory bank in the clamping process are two most basic requirements of equipment, and are key two points which are required to be guaranteed.

In the conventional automatic test line for the memory bank, clamping jaws are generally arranged at two sides of the memory bank, and are respectively provided with a clamping jaw with a guide groove, so that certain guide is provided for products, and stable clamping force is provided. However, the clamping force is not too large, and the clamping force is too large to easily cause the deformation of the product by clamping. And meanwhile, the consistency of the memory strips is guaranteed to be very good, the memory strips cannot have structures such as burrs or uneven thickness, otherwise, the memory strips are easy to block and abrade products.

The existing memory bank clamping claw has low tolerance rate, and has higher requirements on positioning accuracy of the memory bank and the memory bank tester, but the tolerance rate is difficult to ensure in a conventional manual testing machine, wherein the tolerance rate is the capability of clamping the memory bank by the clamping claw when the memory bank is inclined relative to the clamping claw, and the larger the tolerance rate is, namely the larger the inclination angle of the memory bank relative to the clamping claw is. When the positions of the clamping jaws are slightly deviated, the clamping jaws can deviate from the clamping deviation or the cutting hardness deviation is corrected, and the memory strips can displace and mutually rub on the inner walls of the clamping jaws, so that the memory strips are damaged.

As shown in fig. 3, the test system is configured to insert and withdraw the memory bank 6 from the socket 7, specifically, when the memory bank 6 is inserted, the floating clamping jaw clamps the memory bank 6 and guides the memory bank 6 along the socket 7, and due to a positioning error between the manipulator and the socket 7, a situation that the memory bank 6 is inserted but not centered often occurs. When the memory bar 6 is slightly inserted from the center of the slot 7, the slot 7 can be hard extruded and the memory bar 6 can be caused to deviate no matter the memory bar is relatively deviated from the length direction of the slot 7 or the width direction of the slot 7, but the memory bar 6 drives the inner claw 2 to move relative to the outer claw 1 due to the existence of the floating clamping claw, and the floating gap and the elastic buffer structure 3 provide activity and protect the memory bar 6.

When the memory bar 6 is pulled out, the acting force required by pulling out the memory bar 6 is larger, the memory bar 6 is separated from the bottom of the slot 7 and generates larger vibration at the pulling moment, the memory bar 6 also oscillates in the clamping groove 201, at the moment, the memory bar 6 and the inner claw 2 move together, and the elastic buffer structure 3 stretches and absorbs impact accordingly, so that hard extrusion is avoided. At the moment when the memory bar 6 leaves the slot 7, oscillation can be generated as well, and at the moment, impact is buffered and absorbed through the elastic buffer structure 3 so as to play a role in protection.

The memory strip 6 is plugged from the floating clamping jaw to realize replacement of the memory strip 6, the plug-in process is similar to plugging the memory strip 6 from the slot 7, and at the moment, the floating clamping jaw can also effectively avoid hard extrusion. Based on the above, the test system for the memory strip test provides a floating space for the whole test process of the memory strip 6, improves the tolerance rate and greatly reduces the abrasion of the memory strip 6.

Finally, it should be noted that: the foregoing description is only of the preferred embodiments of the utility model and is not intended to limit the scope of the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
