Description

Technical Field

[0001] The utility model relates to a positioning fixture, and more specifically to a secondary positioning fixture used for a lens loading and unloading machine. Background Art

[0002] The production of optical lenses requires multiple processes. The current processing requires manual loading, which is simple, highly repetitive, labor-intensive, and easy for workers to get tired. In addition, manual hands touching the lenses can easily damage the surface quality of the product, resulting in a high defect rate. Therefore, automatic lens loading and unloading machines have appeared on the market to solve the various problems caused by manual operation. Therefore, loading and unloading mechanisms are indispensable in optical lens production lines and can improve the overall production efficiency. However, there is no structure for secondary positioning of lenses in the current loading and unloading machines, making it difficult to ensure that the lenses are accurately grasped in subsequent processes.

[0005] Each of the side guide blocks is provided with two elliptical guide holes, and the elliptical guide holes are provided with bolts fixed to the fixture bottom plate.

[0006] The adjusting assembly comprises an adjusting block fixed on the fixture bottom plate and an adjusting screw laterally screwed on the adjusting block, and the tail of the adjusting screw is connected to the side guide block.

[0007] The tail of the adjusting screw is provided with an annular groove, and the side guide block is provided with a clamping groove for the annular groove to be clamped into.

[0008] The side guide block comprises a bottom block and a positioning block fixed on the left side of the bottom block.

[0009] The left and right sides of the jig bottom plate are both provided with recesses for the bottom block of the side guide block to be embedded.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0015] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0016] like Figure 1 to Figure 2The figure shows a secondary positioning jig for a lens loading and unloading machine, comprising a support block 10, a jig pad 20 fixed on the top of the support block 10, at least one jig base plate 30 fixed on the jig pad 20, two side guide blocks 40 that are movable and symmetrically installed on the left and right sides of the jig base plate 30, a bottom guide block 50 fixed on the lower side of the jig base plate 30, and two adjustment components 60 that are fixed and symmetrically installed on the left and right sides of the jig base plate 30 for pushing the corresponding lateral guide blocks 40 to move. In this embodiment, the jig pad 20 is fixed to the support block 10 by bolts, and the jig base plate 30 is fixed to the jig pad 20 by bolts. The lens A is positioned by the two side guide blocks 40 and the bottom guide block 50 to achieve the effect of secondary positioning of the lens A, which is convenient for the subsequent robot to grasp and perform subsequent processes, and plays a role of transition.
