Description

Technical Field

[0001] The utility model relates to the technical field of chip loading, in particular to a material tray moving device. Background Art

[0002] The existing test equipment for testing chips generally loads the materials through a loading mechanism. The chips are placed in a material tray. Then, by placing the material tray at the loading position, the test equipment clamps the chips in the material tray at the discharge position through its own clamping mechanism. Because the material tray has many placement slots, each placement slot has a chip placed in it. During the clamping process, the chips in the material tray can be clamped completely in sequence through the continuous movement of the clamping mechanism. However, the material tray at the loading position in the existing loading mechanism is not fixed. If the position of the material tray shifts during the clamping process and cannot be reset after the shift, the clamping mechanism will not be able to stably clamp the chips in the material tray, which will cause the chips in the material tray to be clamped too long or cannot be clamped completely. Therefore, a material tray moving device is specially proposed. Utility Model Content

In the present embodiment, the limit block 22 is rotatably installed in the installation cavity 25. When the material tray is placed at the upper material position 11, the side wall of the material tray will squeeze the bearing 23, so that the bearing 23 moves into the installation cavity 25, and the elastic member 24 will give the material tray a reaction force, fixing the material tray between the bearing 23 and the first limit plate 3, so that the two side walls of the material tray are in contact with the side walls of the bearing 23 and the first limit plate 3, and if the material tray moves to the upper material position 11 along the length direction of the frame 1, the setting mode of the rotatable limit block 22 and the rotatable bearing 23 is relative to the setting mode of the limit block 22 sliding along the width direction of the frame 1, and the pressure between the two is smaller when they are in contact, and the entry of the material tray is smoother.

Except for the lowest tray, the remaining trays are supported by the first support plate 92, and the lowest tray is supported by the second support plate 102 and continues to descend until the second support plate 102 descends to a position lower than the transport plate 63. At this time, the tray is placed on the transport plate 63, and then fixed by the stop plate 652 and the second clamping part 646, and then it can be transported, thereby realizing the transportation of the tray. It can be known that when the transport assembly is transported to the discharge position 12, the transport assembly is located between the two second support plates 102, and when it moves to the discharge position 12, the transport assembly is located between the two second limit assemblies 4, so that the transport assembly will not be interfered when it is transported along the length direction of the frame 1.

[0053] In addition, a lower material position 14 is also provided on the frame 1. The lower material position 14 is located on the two side walls of the frame 1 and a second support assembly 15 is provided. The second support assembly 15 includes a linear drive device and a third support plate. The linear drive device is used to drive the third support plate to move along a linear motion to support the material tray group. Similarly, two second lifting assemblies 16 with the same structure as the first lifting assembly 10 are provided in the frame 1. The second lifting assembly 16 cooperates with the second support assembly 15 to realize the stacking of the material trays at the lower material position 14. Specifically, after the conveying assembly conveys the material tray from the upper material position 11, the second lifting assembly 16 is actuated, and the support plate in the second lifting assembly 16 causes the material tray to rise above the third support plate, and the third support plate extends out. At the same time, the support plate in the second lifting assembly 16 descends until the material tray is placed on the third support plate, and then the support plate in the second lifting assembly 16 returns to its original position, and the cycle is repeated to stack the material trays at the lower material position 14.

Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
