Scribing machine

Abstract

The invention provides a scribing machine. The scribing machine comprises a machine table, a scribing knife shifting device and a scribing knife device, wherein the scribing knife shifting device is fixed to the surface of the machine table, the scribing knife device is connected with the scribing knife shifting device and is used for scribing on the surface of a test sample. The scribing knife shifting device comprises an X-direction horizontal sliding device, a Y-direction horizontal sliding device and a Z-direction vertical sliding device. The scribing knife device is fixedly arranged at the position of the Z-direction vertical sliding device, and an object stage is further arranged on the surface of the machine table and used for supporting and fixing the test sample. The scribing machine can realize full-automatic scribing on the surface of the test sample, and the grid-scribing speed is high and the entire process is uniform in force.

Description

technical field [0001] The invention relates to a test device for a cross-cut test, in particular to a marking machine for a cross-cut test used for testing the adhesion of decorative coatings on the surface of test samples such as glass panels, touch screens, and display panels. Background technique [0002] With the development of science and technology, electronic glass products such as glass panels, touch screens or display panels are more and more commonly used in electronic products such as mobile phones and tablet computers; The surface of the product is usually equipped with a decorative coating structure. In order to prevent the decorative coating structure from falling off during the use of this type of product, the performance of the coating and the materials used to make the coating is usually evaluated, that is, the cross-cut method is used to evaluate the material. To evaluate the adhesion of the coating; in the cross-cut test of the coating, the commonly used ...

Problems solved by technology

[0003] The traditional 100-grid test is to manually hold the 100-grid knife to scratch the surface of the test sample. When manually operating the 100-grid knife, the human hand is easy to swing from side to side, and it is impossible to ensure that the entire scribing process is evenly applied. The line spacing error is large, and there are errors such as slanting lines and different depths of scribing lines, which directly lead to inaccurate evaluation results of adhesion and distorted performance evaluation results of coating materials

[0004] In order to solve the shortcomings of the traditional 100-grid test using a manually-operated 100-grid knife with relatively large errors, Chinese patent number ZL201720599326.X, named as a scribing machine, discloses a scribing machine structure, which includes a bracket, a load platform and adjustment assembly and scratcher; a first sliding structure is provided on the surface of the support, and a second sliding structure is provided on the surface of the loading table adjacent to the support, and the second sliding structure is connected to the first sliding structure. A sliding structure is slidably matched so that the object table slides relative to the first sliding structure; and the adjustment assembly includes a mounting rod, a rotating shaft, a rotating arm and a weight, and the rotating arm is provided with a mounting position, so The weight is detachably arranged on the installation position; when marking the surface of the test sample, the test sample is first fixed on the stage, the weight is installed on the installation rod, and the position is rotated The scratching knife at the end of the arm contacts the surface of the test sample on the stage, so that the stage moves along the direct direction, draws a straight line on the surface of the test sample, and then removes the test sample from the stage and rotates 90 degrees After that, it is fixed again and the scribing action is repeated; then the scribing knife is drawn on the surface of the test sample to draw a grid; the scribing action is completed; although the scribing equipment solves the problem caused by uneven application of force during manual scribing to a certain extent There are technical defects such as a large error in the distance between the scribing lines, inclined scribing lines, and different depths of the scribing lines; When the line is drawn, it is necessary to adjust the position of the test sample at least twice to complete the operation of marking the grid. The process of marking the line is cumbersome and inefficient; Machine structure is further improved
