Description

Technical Field

[0001] The utility model relates to the technical field of laser radar window printing, and in particular to a laser radar window positioning printing device. Background Art

[0002] In order to make the surface of some laser radar windows on the market have a certain conductive function, conductive silver paste is often printed at a designated position on the surface to meet the directional performance requirements of the product. However, since the printing surface is usually not a conventional printing plane, it often has a certain curvature. Especially when there is an interference structure around the printed pattern, the printing head will cause a lot of deformation when taking ink and pressing down for printing, thus affecting the final printing effect, causing dimensional deviation, and even deformation and distortion.

[0003] When two kinds of logos are to be printed on the curved surface of the laser radar window, two sets of tooling are often used to print the logo patterns on both sides of the product. In the actual printing process of this printing method, the logo patterns on both sides of the product need to switch the printing tooling and the corresponding rubber head positions back and forth due to the different printing positions, which wastes the machine adjustment time, is inefficient, and has poor printing effect on the product. Utility Model Content

[0004] The utility model aims to provide a printing device for a laser radar window.

[0005] The utility model provides the following technical solutions:

[0006] The utility model proposes a laser radar window positioning printing device, comprising a pad printing machine, a connecting plate fixed on the pad printing machine, a slide fixed on the connecting plate, a printing tool for placing the radar window fixed on the movable end of the slide, the lower end surface of the printing rubber head of the pad printing machine has an arc portion that can fit with the upper surface of the radar window, and the printing rubber head is provided with a groove for avoiding the printing tool.

[0007] Furthermore, sensors are fixed on both sides of the front of the slide.

[0008] Furthermore, grooves that match the laser radar windows are provided on both left and right sides of the upper surface of the printing tool.

[0009] Furthermore, a connecting opening is provided between the grooves for facilitating taking out the laser radar window.

[0010] Furthermore, a hand-holding opening communicating with the groove is provided on the edge of the printing tool, and the hand-holding opening corresponds to the communicating opening.

[0011] Furthermore, a field-shaped adsorption port is provided on the printing tool under the groove, and an adsorption hole is provided in front of the printing tool. The field-shaped adsorption port is connected to the adsorption hole through an adsorption channel provided in the printing tool.

[0012] Compared with the prior art, the utility model realizes the left and right movement of the printing tooling through a slide table, and senses the position of the printing tooling through a sensor, thereby solving the problem of the prior art that printing a laser radar window requires separate process debugging of logos on both sides, and realizes the requirement of high-precision printing of logo patterns on both sides of the laser radar window printing surface. At the same time, it also avoids the problem of needing to re-adjust and switch the position of the tooling and the rubber head when printing two logo patterns on the laser radar window, thereby reducing the machine adjustment and debugging time.
