Description

Technical Field

[0001] The utility model relates to the technical field of lens processing, in particular to an automatic thickness measuring mechanism of a core taking machine. Background Art

[0002] When an existing core extraction machine processes a lens, it is necessary to measure the thickness of the lens before processing to distinguish lenses that do not meet the thickness requirements. The existing method is to measure manually, which is inefficient and costly. In addition, when the lens is manually installed in the processing area of ​​the core extraction machine, the positioning accuracy of the lens is poor. Therefore, an automatic thickness measurement mechanism for a core extraction machine is proposed. Utility Model Content

[0003] In order to solve at least one of the above-mentioned technical shortcomings, the utility model provides an automatic thickness measurement mechanism for a core extractor, including a micrometer fixed on the front outer wall of the core extractor, the micrometer display of the micrometer is fixed directly above the PLC controller of the core extractor, a manipulator is provided directly above the processing area of ​​the core extractor, and a measuring component fixed on the processing axis of the core extractor is provided at the end of the pin of the micrometer.

[0004] Furthermore, the measuring assembly includes a fixing rod fixed on the processing shaft of the core extractor, a connecting block is provided at the outer end of the fixing rod, a measuring block is connected to the top of the connecting block through a threaded hole and a bolt, and the measuring block is located at the end of the thimble of the micrometer. Beneficial Effects

[0005] When processing the lens, the robot takes and puts the material, and sends the lens to the processing area through the robot. As the processing progresses, the measuring component follows the movement of the processing axis of the core-taking machine, so that the measuring component is close to the ejector pin of the micrometer. The measuring component contacts the ejector pin of the micrometer, and judges whether the lens is a qualified product through the data measured by the micrometer. When the thickness data measured by the micrometer is consistent with the thickness data of the qualified lens, the PLC controller controls the core-taking machine to start processing. When the thickness measured by the micrometer does not meet the standard, it is a defective product. The PLC controller controls the robot to take the lens and place it in the placement box for defective products, realizing automatic measurement and automatic processing, thereby improving production efficiency.

[0006] The realization of the purpose, functional features and advantages of the present invention will be further described in conjunction with embodiments and with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0010] Please refer to Figure 1 to Figure 2 ;

[0011] This embodiment provides a core extraction machine automatic thickness measurement mechanism, refer to Figure 1 , including a dial gauge 4 fixed on the front outer wall of the core extractor 1, a dial gauge display 401 of the dial gauge 4 is fixed directly above the PLC controller 3 of the core extractor 1, a manipulator 2 is provided directly above the processing area of ​​the core extractor 1, and a measuring component 5 fixed on the processing axis of the core extractor 1 is provided at the end of the ejector pin of the dial gauge 4;

[0012] In specific implementation, when processing the lens, the robot 2 takes and puts the material, and the lens is sent to the processing area by the robot 2. As the processing proceeds, the measuring component 5 moves with the processing axis of the core extractor 1, so that the measuring component 5 is close to the ejector pin of the micrometer 4, and the measuring component 5 contacts the ejector pin of the micrometer 4. Through the data measured by the micrometer 4, it is judged whether the lens is a qualified product. When the thickness data measured by the micrometer 4 meets the thickness data of the qualified lens, the PLC controller 3 controls the core extractor 1 to start processing. When the thickness measured by the micrometer 4 does not meet the standard, it is a defective product. The PLC controller 3 controls the robot 2 to take the lens and put it into the placement box of defective products, so as to realize automatic measurement and automatic processing, thereby improving production efficiency.

[0013] Among them, the lens is picked up and put down by the robot 2, which improves the processing accuracy, facilitates the center positioning of the lens, and facilitates processing.

[0014] For further reference, Figure 2 The measuring assembly 5 includes a fixing rod 503 fixed on the processing shaft of the core extractor 1, a connecting block 502 is provided at the outer end of the fixing rod 503, a measuring block 501 is connected to the top of the connecting block 502 through a threaded hole and a bolt, and the measuring block 501 is located at the end of the ejector pin of the micrometer 4;

[0015] In specific implementation, when measuring, the fixed rod 503 moves with the processing axis of the core extractor 1, and the fixed rod 503 drives the measuring block 501 to move parallel to the processing axis of the core extractor 1 through the connecting block 502, so that the movement distance of the processing axis of the core extractor 1 is equal to the distance of the measuring block 501. When measuring the thickness of the lens, the measuring block 501 is close to the ejector pin of the micrometer 4, so that the ejector pin is squeezed, and the micrometer 4 determines whether the lens is a good product based on the measured data;

[0016] If the lens is good, the PLC controller 3 controls the core extraction machine 1 to process the lens;

[0017] If there is no defective product, the PLC controller 3 controls the robot 2 to take the lens away and put it into an external defective product placement box.
