Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise. All directional indicators (such as up, down, left, right, front, and rear … …) in the embodiments of the present invention are only used to explain the relative position relationship between the components, the motion situation, and the like in a specific posture, and if the specific posture is changed, the directional indicator is changed accordingly.

The technical solution of the present invention is further described below by way of examples:

the utility model provides a core deviation detection tool of batch aspheric surface glass lens, as shown in FIG. 1, core deviation detection tool includes: the device comprises a substrate 1, a plurality of chucks 2 and a carrier 3, wherein the plurality of chucks 2 are positioned on the substrate 1, and the carrier 3 is detachably fixed with the plurality of chucks 2; as shown in fig. 2, the substrate 1 has a receiving hole 11, the collet 2 extends into the receiving hole 11, the carrier 3 is located in the receiving hole 11, and the upper surface and the lower surface of the substrate 1 both have three reference balls 12 which are not on the same straight line; as shown in fig. 4, the carrier 3 has a plurality of detection grooves 31, and the bottom of the detection grooves 31 has detection holes 32. When the aspheric glass lens is detected, a batch of lenses can be placed in the detection groove 31 of the carrier 3, then the carrier 3 is installed between the chucks 2 and is positioned in the accommodating hole 11, the detection equipment determines two reference surfaces through the six reference balls 12 on the two surfaces of the substrate 11, and then the lenses on the fixture 3 are detected one by one through the probe, so that the eccentricity of the lenses is obtained.
