Problems solved by technology

[0009] For this reason, the technical problem to be solved by the present invention is that the method for marking the position of the screw by using a laser marking machine in the prior art cannot display multiple light spots at the same time, and the bulky laser controller is not conducive to the installation and debugging on the equipment. The price is expensive and the cost performance is low, and the laser will cause certain harm to the operator's eyes

Embodiment Construction

[0044] Such as figure 1 As shown, a kind of projector-based instruction guidance method of the present invention comprises the following steps:

[0045] S1: Connect the PC to the projector, and set the extended interface of the PC, so that the PC itself displays the main interface, and the projector displays the extended interface. The system composition of the present invention is as figure 2 As shown, it includes a PC and a projector, and the PC and the projector are connected through HDMI.

[0046] S2: Set the projection background color, and set the projection background as the first color through program control. In this embodiment, the color of the projection background is set to be completely black.

[0047] S3: Establish the relationship between the projected coordinates of the screw and the actual coordinates of the screw. Such as image 3 As shown, the step S3 specifically includes the following steps:

[0048] S31: Clamp and fix the product on the carrier, an...

Abstract

The invention discloses an instruction guiding method based on a projector. According to the invention, a PC expansion interface is projected through the projector, the color of an interface background is set to be black, and then the positions of all screws are taught and saved in a projection interface. When the positions of unqualified screws are displayed, a color different from the background color is used for projecting light spots to the screws to facilitate an operator to complete different operations according to different instructions. According to the invention, the projection of the light spots is not limited, and simultaneously all positions and the colors and sizes of the light spots can be arbitrarily set, the light spots are harmless to the operator, and the projector is low in cost and convenient to maintain.

Description

Technical field: [0001] The invention belongs to the technical field of precise measurement, and in particular relates to a projector-based instruction guidance method. Background technique: [0002] In order to better control the assembly quality of the keyboard during the production process of the notebook computer, the most intuitive way to judge whether the screw fixing the keyboard is OK through the equipment is to shine a beam of light on the NG screw to guide the operator to work. [0003] To achieve the above functions in previous projects, laser marking machines were usually used to mark the screw positions. The disadvantages of this method are as follows: [0004] 1. The number of laser spots is limited by the frequency and cannot display multiple spots at the same time. If there are many NG screw positions on the product, they can only be displayed separately; [0005] 2. The bulky size of the laser controller is not conducive to the installation and debugging on...
