Description
Technical Field
[0001] The utility model relates to the technical field of chip testing equipment, and more particularly, to a position calibration device and a translational testing and sorting machine. Background Art
[0002] With the increasing integration of semiconductor chips, their product sizes are getting smaller and smaller. For translational loading machines or translational testing and sorting machines, such translational devices with small chip sizes and high simultaneous testing numbers require higher motor precision and higher picking and placing precision of the picking and placing device. Generally, the minimum chip size for which a translational device can ensure picking and placing precision is 2mm x 2mm. Currently, translational testing and sorting machines or taping machines generally use trays for feeding. For trays, when designing their sizes, it is necessary to consider both minimizing the wobbling of the chips after being placed in the trays and having a large enough deviation when the chips are placed in the trays to avoid warping of the chips when placed in the trays. Therefore, generally, trays will have a certain positive size tolerance. At this time, before the translational device picks up the chips from the tray and places them into the test fixture, a position calibrator capable of calibrating the chip position needs to be provided at the suction head position. Generally, translational devices will have 8 or more suction heads capable of simultaneously picking and placing chips. Currently, most equipment manufacturers use position calibrators with fixed positions. First, the equipment places the chips into the position calibrator, and then the chips slide or are scraped through the chamfer of the position calibrator and are moved into the tray, and then are sucked onto the suction head to complete position calibration. Such fixed-position position calibrators have many alarms, especially when the chip size is less than 2mm x 2mm, the equipment alarms particularly frequently, and it is basically impossible to ensure the stable operation of the equipment. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a position calibration device and a translational testing and sorting machine, which can calibrate the actual position of the chips, thereby significantly improving the matching precision of the relative positions between the chips and the suction heads in subsequent processes, and further avoiding the situation where the equipment cannot operate stably due to frequent alarms.

[0028] Please refer toFigures 1 to 3 , an embodiment of the present application provides a position calibration device 100, which includes a bracket 10 and a jig 20 slidably disposed in the bracket 10. A plurality of material placing openings 121 are provided on the top surface of the bracket 10, and a plurality of limiting members 21 are provided on the top surface of the jig 20. The limiting members 21 are received in the material placing openings 121. The jig 20 is driven to move relative to the bracket 10, driving the limiting members 21 to move relative to the material placing openings 121 to adjust the caliber of the material placing openings 121. The position calibration device 100 can calibrate the actual position of the chip, thereby significantly improving the matching accuracy of the relative position between the chip and the suction head in the subsequent process, and further avoiding the equipment from being unable to operate smoothly due to frequent alarms.
[0029] It should be noted that, as Figures 1 to 3 shown, the position calibration device 100 includes a bracket 10 and a jig 20. Among them, a sliding cavity is provided in the bracket 10, and the jig 20 is slidably disposed in the sliding cavity so that the jig 20 can slide relative to the bracket 10 along the inner wall of the sliding cavity, thereby changing the relative position between the jig 20 and the bracket 10. As Figure 1 and Figure 3 shown, a plurality of material placing openings 121 are provided on the top surface of the bracket 10, and the designed caliber of the material placing openings 121 is larger than the actual size of the chip to facilitate the equipment to place the chip in the material placing openings 121. In order to calibrate the actual position of the chip after the chip is placed in the material placing openings 121, as Figure 1 and Figure 2 shown, a plurality of limiting members 21 are provided on the top surface of the jig 20. Among them, the plurality of limiting members 21 are respectively received in the plurality of material placing openings 121 so that the actual position of the chip in the material placing opening 121 where the limiting member 21 is located can be calibrated through the limiting member 21.
[0030] Specifically, in the actual use process, when the jig 20 is driven by an external force to move relative to the bracket 10 along the inner wall of the sliding cavity, since the limiting member 21 is fixedly disposed on the top surface of the jig 20, the jig 20 can drive the limiting member 21 to move synchronously relative to the bracket 10, thereby changing the relative position between the limiting member 21 and the material placing opening 121. In this way, the designed caliber of the material placing opening 121 can be designed to be larger to ensure that it is easier for the equipment to place the chip in the material placing opening 121. After the chip has been placed in the material placing opening 121, only by driving the jig 20 to move relative to the bracket 10 by an external force, the limiting member 21 can be driven to move synchronously relative to the material placing opening 121, so that the limiting member 21 abuts against the chip, and then drives the chip to move in the material placing opening 121 until the outer edge of the chip is simultaneously abutted by the inner wall of the material placing opening 121 and the inner wall of the limiting member 21.
[0031] Compared with the fixed position calibrator in the prior art, the position calibration device 100 provided in the present application can drive the fixture 20 to move relative to the bracket 10, drive the limiter 21 to move relative to the discharge port 121, and then push the chip to move relative to the discharge port 121, and finally achieve the effect that the outer edge of the chip is simultaneously supported by the inner wall of the discharge port 121 and the inner wall of the limiter 21. Therefore, through the above-mentioned position calibration operation, the actual diameter of the discharge port 121 can be changed so that the actual diameter of the discharge port 121 can be adjusted according to actual needs, for example, from the original larger design diameter to match the smaller actual size of the chip. In summary, the position calibration device 100 can calibrate the actual position of the chip in the discharge port 121, and then when the device sucks and releases the chip through the suction head, it can significantly improve the matching accuracy of the relative position between the chip and the suction head.
[0032] As an implementation method, Figure 1 and Figure 2 As shown, the position calibration device 100 further includes a driving member 30, which is in transmission connection with the fixture 20 and is used to drive the fixture 20 to move relative to the bracket 10. For example, Figure 1 and Figure 2 As shown, the driving member 30 can be fixedly connected to the bracket 10 through the connecting member 32, and a through hole is provided on the bracket 10 so that the driving member 30 can extend into the bracket 10 through the through hole to connect with the fixture 20.
[0033] Considering that the cross-sectional shape of a general chip is mostly rectangular, as an implementation method, Figure 1 and Figure 3 As shown, the cross-sectional shape of the discharge port 121 is a rectangle. Figure 1 and Figure 2 As shown, the cross-sectional shape of the stopper 21 is L-shaped, and the two sides of the L-shape are arranged correspondingly to the two adjacent sides of the rectangle. In this way, when the stopper 21 moves relative to the discharge port 121, the two sides of the L-shape can cooperate with the other two sides of the rectangle (which are arranged diagonally to the two sides of the L-shape) to support the four sides of the chip.
[0034] Of course, in other embodiments, the cross-sectional shape of the discharge port 121 and the cross-sectional shape of the stopper 21 can also be other shapes, as long as the cross-sectional shape of the discharge port 121 and the cross-sectional shape of the stopper 21 are adapted to the cross-sectional shape of the chip, and no specific limitation is made here. For example, when the cross-sectional shape of the chip is circular, the cross-sectional shape of the discharge port 121 is circular and the cross-sectional shape of the stopper 21 is arc-shaped to match it, so that the outer edge of the chip can be simultaneously supported by the inner wall of the discharge port 121 and the inner wall of the stopper 21.
[0035] As an implementation method,Figure 1 and Figure 2 As shown in Figure 2 , the number of driving members 30 is one, and the telescopic direction of the driving member 30 is parallel to the diagonal direction of the rectangle. Or rather, the driving member 30 can perform telescopic movement along the diagonal direction of the rectangle, so that the jig 20 is driven to move relative to the bracket 10 along the diagonal direction of the rectangle. The advantage of such a design is that the jig 20 only needs to move along the diagonal direction of the rectangle once, so that the outer edge of the chip can be simultaneously abutted by the inner wall of the feeding port 121 and the inner wall of the limiting member 21.
[0036] Of course, in other embodiments, as an implementable manner, the number of the driving members 30 can also be two, and the telescopic directions of the two driving members 30 are respectively parallel to the two side directions of the L shape. The jig 20 is driven to move relative to the bracket 10 along the two side directions of the L shape in sequence. That is to say, during actual use, the driving member 30 can first perform telescopic movement along one of the side directions of the L shape to calibrate the actual position of the chip in this direction, and then perform telescopic movement along the other side direction of the L shape to calibrate the actual position of the chip in this direction, so as to finally achieve the purpose of position calibration through two movements in different directions (the front and rear side directions are perpendicular to each other).
[0037] As an implementable manner, as shown in Figure 1 and Figure 3 As shown in Figure 3 , an avoidance groove 13 is provided on the bracket 10 for making way for the telescopic shaft 31 of the driving member 30. Among them, the actual shape of the avoidance groove 13 should match the movement stroke of the driving member 30 and the telescopic shaft 31 of the driving member 30, and the shape shown in the drawings does not play a restrictive role.
[0038] As an implementable manner, the above-mentioned driving member 30 can be a pneumatic cylinder, a hydraulic cylinder or a linear motor, as long as the driving member 30 can drive the jig 20 to perform a linear motion. Those skilled in the art should be able to make a reasonable selection and design according to the actual situation, and no specific limitation is made here.
[0039] As an implementable manner, as shown in Figures 1 to 3 As shown in Figures 1 to 3 , the bracket 10 includes a base 11 and a cover plate 12. The base 11 has a receiving groove, and the jig 20 is slidably disposed in the receiving groove (i.e., the above-mentioned sliding cavity). The cover plate 12 is detachably covered on the base 11 to close the top notch of the receiving groove. Exemplarily, the base 11 and the cover plate 12 can be fixedly connected through mounting holes and fasteners (not shown in the figure) provided around. When the base 11 and the cover plate 12 are also fixedly connected through the mounting holes and fasteners provided at the middle position of the bracket 10, the mounting holes and fasteners provided at the middle position of the bracket 10 need to make way for the movement of the jig 20 relative to the bracket 10.
[0040] As an implementable mode, as Figure 1 shown, a plurality of material discharge openings 121 are arranged in an array, and a plurality of limiting members 21 are respectively accommodated in the plurality of material discharge openings 121, which can significantly improve the processing efficiency of the equipment.
[0041] The embodiment of the present application further provides a translational test and sorting machine, including the above-mentioned position calibration device 100. Since the structure and beneficial effects of the position calibration device 100 have been described in detail in the foregoing embodiments, they will not be repeated here.
[0042] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
[0043] In addition, it should be noted that, in the above specific embodiments, the various specific technical features described can be combined in any suitable manner without conflict. To avoid unnecessary repetition, the present utility model will not separately describe various possible combination methods.
