Track paperboard for intelligent tracking trolley and manufacturing method of track paperboard

Abstract

The invention discloses a track paperboard for an intelligent tracking trolley and a manufacturing method of the track paperboard. The manufacturing method comprises the steps that copperplate body paper is adopted as a base layer of the track paperboard, white paint is painted on the copperplate body paper to form a white background layer, then black ink is printed on the white background layer in a printing mode, a layer of sub-film covering the white background layer and the black ink is arranged on the copperplate body paper, and the track paperboard which does not reflect or almost does not reflect infrared light can be obtained. The manufacturing method of the track paperboard is simple in manufacturing process and low in cost, and the track paperboard can well reduce or even eliminate mirror reflection of the surface of the track paperboard to infrared rays, so that the intelligent tracking trolley can more accurately judge whether a trolley body is on a track or not, and the situation of misjudgment of the trolley is reduced.

Description

technical field [0001] The invention relates to the technical field of cardboard processing, in particular to a track cardboard for an intelligent tracking car and a manufacturing method thereof. Background technique [0002] Smart tracking car is a car that can run along a specific track. It mainly uses two infrared sensors arranged side by side at the bottom of the car to set a black track in the plane where the car runs, and set the other areas of the black track to white. When the car is running, infrared light is continuously emitted to the ground. When the infrared light meets the white paper floor, diffuse reflection occurs, and the reflected light is received by the photosensitive transistor installed on the car. If it encounters a black track, the infrared light is absorbed. The phototransistor on the trolley cannot receive infrared light, and the single-chip microcomputer inside the trolley determines the position of the black track and the walking route of the tro...

Problems solved by technology

Although this method is simple, there were certain problems at the time: users needed to purchase additional black tape and white paper, and it took a long time to make track cardboard, which greatly affected beginners' DIY interest in smart tracking cars. Secondly, due to The surface of the tape is smooth and has a certain emission effect on infrared rays, which may easily lead to misjudgment of non-program design errors in the microcontroller, affecting the experience of beginners

[0004] Another way is to place infrared-absorbing paint on white cardboard. However, the preparation of the paint is complicated and the cost is high. As a result, it is neither economical nor convenient for mass production to use the paint to make the walking track of the trolley.
