Description

Technical Field

[0001] The invention relates to the technical field of alignment, in particular to a product manual feeding alignment device and an alignment and debugging method. Background Art

[0002] At present, the main alignment methods in the market are manual alignment (mechanical edge alignment) and automatic alignment (CCD) image-guided alignment). Automatic alignment is generally CCD image-guided + platform correction. This method has high equipment integration and requires an automatic adjustment structure configured by the mechanism, and is matched with a visual industrial computer, etc. It is mostly used in automation equipment, but its cost is high. Manual alignment generally uses mechanical alignment, and sets an XY alignment edge on the fixture platform. It is mostly used in semi-automatic machines. Although the cost is low, it is only suitable for loading workpieces with flat surfaces. However, if the product has a special-shaped curved surface, it is necessary to ensure the XY position and the θ angle deviation of the product when loading. The general manual mechanical positioning cannot meet the requirements. To ensure accurate loading in the market, R&D personnel usually design contoured loading jigs, transport jigs and working jigs to accurately place the product for processing. However, these three usually have reference deviation problems during use, resulting in unqualified product processing. The existing means to solve this problem are usually to set corresponding scale lines on the corresponding bases where the jigs are installed. As long as the jigs are aligned with the scale lines, they are aligned; but after long-term use, the bases are inevitably offset to a certain extent, which will result in the situation that even if they are aligned, the positioning bases of the three cannot be adjusted to be consistent, and users need to explore and debug based on experience; and it may also happen that the scale lines are covered by oil, dust, etc. and cannot be seen clearly.

A centering and debugging method for a manual product feeding and positioning device according to any one of claims 1 to 9, characterized in that: Follow these steps to debug: Step S1, installing the centering shaft on the working base, so that the centering shaft cooperates with the sixth positioning portion of the working base to achieve planar alignment, and so that the first positioning portion of the centering shaft cooperates with the second positioning portion of the working base to align, so as to achieve positioning alignment of the centering shaft and the working base in the circumferential direction; Step S2, moving the transport arm to drive the mounting seat to move closer to the centering shaft, and then fine-tuning the mounting seat along the radial direction of the centering shaft so that the sixth positioning of the mounting seat is aligned with the centering shaft in the radial direction; Step S3, adjust the mounting seat to rotate around the axis of the centering shaft body, so that the second positioning portion of the mounting seat is aligned with the first positioning portion at the other end of the centering shaft body, so that the centering shaft body and the mounting seat of the transport arm are positioned in the circumferential direction, and the centering of the mounting seat and the working base is completed, and then the centering shaft body can be separated from the working base; Step S4, ensure the connection between the centering shaft and the mounting seat, move the mounting seat by the transport arm, move the centering shaft to the loading base, and make fine adjustments to align the centering shaft with the sixth positioning portion of the loading base, then rotate the loading base to rotate around the centering shaft, so that the second positioning portion of the loading base and the first positioning portion of the centering shaft are aligned, so that the loading base and the mounting seat can be aligned, and the centering shaft is removed; Step S5, installing the loading jig on the loading base so that the third fixed portion is aligned and fixed with the second positioning portion of the loading base; Install the transport jig on the mounting seat so that the fourth positioning portion of the transport jig is aligned and fixed with the second positioning portion of the mounting seat; install the working jig on the working base so that the fifth positioning portion of the working jig is aligned and fixed with the second positioning portion of the working base.
