[0002] With the development of vehicle interiors, many high-end models use LEDs to display various auxiliary information in the center console area. As a result, the center console needs to use glass material technology, and various patterns on the glass are required to match the LED backlight display effect.

[0003] When the existing vehicle-mounted exposure machine exposes graphics on vehicle glass, it is necessary to measure the entire glass surface. The existing sensor is used to collect and calculate the distance from the lens to the surface of the object to be exposed. This measurement process takes a long time, and the measurement standards need to be reset for glass surfaces of different specifications and sizes, which leads to reduced measurement efficiency and low versatility. For this reason, we proposed a Z-axis curve motion training method for vehicle-mounted glass exposure. Summary of the invention

[0004] The purpose of the present invention is to provide a vehicle glass exposure Z-axis curve motion training method to solve the problems raised in the above background technology that lead to reduced measurement efficiency and low versatility.

[0011] Step 6: Measure the Z-axis degrees at the starting point and the center point, and calculate the Z-axis motion compensation data.

[0012] Preferably, the straight-line distance between the left and right ends of the workpiece to be measured is first measured to obtain the chord length of the workpiece to be measured, and the distance from the midpoint of the chord length to the top of the curved arc is measured to obtain the arch height. The arc length (actual width of the glass) and radius can be calculated from the chord length and the arch height.

[0013] Preferably, the measurement starting point and center point data are transmitted to the exposure device through the measuring device, and the exposure device performs motion compensation. After the setting is completed, the exposure device is used normally.

[0014] Preferably, the measuring equipment model is Renishaw PH10M+SP25.

[0015] Preferably, the Z-axis degree measured at the measurement starting point and the measurement center point is equal to the Z-axis degree measured at the measurement center point and the measurement end point.

[0016] Preferably, the measuring device can perform measurement from the measuring center point to the measuring starting point or from the measuring center point to the measuring end point with the Z axis as the axis.

[0017] Preferably, the measuring device comprises a distance measuring sensor and an infrared sensor, the distance measuring sensor is used to measure the degree of the workpiece, and the infrared sensor is used to measure the size of the workpiece.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: the vehicle-mounted glass exposure Z-axis curve motion training method measures the straight-line distance between the left and right ends of the workpiece to be measured by an infrared sensor to obtain the chord length of the workpiece to be measured, and then calculates the specific width and radius of the workpiece, and sets the measurement points according to the obtained dimensions, and the measuring device transmits the measured measurement starting point and measurement center point data to the exposure device, and the exposure device performs motion compensation.
