It is worth noting that the following embodiments are only used to explain the present application and do not constitute a limitation on the present application.
[0027] Embodiment 1:
[0028] like Figure 1-3 As shown, a precision reference device for size detection used for safe placement of brittle workpieces comprises: a plane reference 1, a lifting support 2, a lifting mechanism, and a driving mechanism. The plane reference 1 is annular, used for placing workpieces, and is mounted on a base 6. The base 6 is also annular and is mounted on a mounting plate 5. The lifting support 2 is arranged in the inner cavity of the plane reference 1. The lifting mechanism is connected to the lifting support 2. The starting mechanism is used to drive the lifting mechanism to perform an ascending or descending movement.
[0029] The plane reference 1 is made of hard material, and is provided with a plurality of limit grooves. The upper part of the lifting support 2 is provided with a plurality of outwardly facing flanged support blocks, and the flanged support blocks are correspondingly arranged in the limit grooves. The upper part of the plane reference 1 is all on the same horizontal plane, and the shape of the limit grooves matches the shape of the flanged support blocks, and the flanged support blocks can slide up and down in the limit grooves. This structure is arranged to facilitate smoother picking and placing of workpieces.
[0030] A soft protective layer is provided on the upper part of the flange support block, which is used to achieve soft contact when placing brittle workpieces, and can play a protective role for the workpieces.
[0031] The lifting mechanism includes a lifting plate 9, a guide sleeve 7, a guide shaft, and a lifting screw mechanism 8. The guide shaft is provided with 4 groups and is arranged around the lifting plate 9. The guide sleeve 7 is slidably arranged on the guide shaft. The four top corners of the lifting plate 9 are respectively connected to the guide sleeve 7; the lifting plate 9 is connected to the top of the lifting screw mechanism 8, and the lifting screw mechanism 8 is connected to the driving mechanism through a horizontal screw; the lifting screw mechanism 8 can include a vertical screw, the upper and lower ends of the vertical screw are both located in the sliding sleeve, and the top of the vertical screw is connected to the lifting plate 9, and the lower part of the vertical screw is meshed with the horizontal screw. The vertical screw is driven to rise or fall by the rotation of the horizontal screw, and the horizontal screw can be driven by the motor 3 through the meshing of a set of bevel gears. The driving mechanism includes a motor 3 and a reducer 10.
[0032] In some embodiments, the limiting grooves are arranged at equal intervals, and the flange support blocks are arranged at equal intervals. The equal intervals between the two can make the flange support blocks bear force evenly, and the up and down sliding in the limiting grooves is more stable.
[0033] In some embodiments, a position sensor 4 is further included, and the position sensor 4 is used to detect the height of the lifting plate 9, and the position sensor 4 is connected to the driving mechanism.

[0035] 1) Turn on the motor, the motor drives the lifting mechanism to lift the lifting support, and the brittle workpiece is reliably placed on the lifting support, and the plane of the workpiece coincides with the flange support block on the upper end surface of the lifting support;
[0036] 2) The lifting support slowly descends until the workpiece plane contacts the plane reference, and the upper end surface of the lifting support is kept parallel to the plane reference during the descent;
[0037] 3) The lifting support continues to descend until the upper end surface of its flange support block is lower than the plane reference, so that the workpiece falls completely onto the plane reference, and the inspection starts and completes;
[0038] 4) The lifting support is slowly raised until the upper end surface contacts the plane of the workpiece, and the upper end surface of the lifting support is kept parallel to the plane reference during the rise; the brittle workpiece is ensured to be safely separated from the plane reference by slowly rising.
[0039] 5) The lifting support continues to rise until the upper end surface is higher than the plane reference, so that the workpiece is completely separated from the plane reference and the workpiece is removed.
[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
