Detailed ways

In order to fully understand the purpose, features and effects of the present utility model, the utility model is described in detail through the following specific embodiments and accompanying drawings, as follows:

Please refer to FIG. 2A and FIG. 2B . FIG. 2A and FIG. 2B are a front view and a side view of a vertical etching mechanism according to an embodiment of the present invention. As shown in the figure, a vertical etching mechanism according to an embodiment of the present invention is used to etch a glass substrate 1, and includes an etching chamber 10, a motor 20, a plurality of driving rollers 30, and a plurality of first auxiliary guide wheels 40. A plurality of second auxiliary guide wheels 50, a plurality of first nozzles 60 and a plurality of second nozzles 70. The etching chamber 10 is used for accommodating the conveying device and the glass substrate 1 therein, and etching the glass substrate 1 . The motor 20 is disposed under the etching chamber 10 to provide power to transport the glass substrate 1 . The transmission roller 30 is connected with the motor 20 by a transmission rod 32, and the center of the transmission roller 30 has a recess 34 to accommodate the glass substrate 1, whereby when the motor 20 starts to drive When the driving roller 30 rotates, the glass substrate 1 accommodated in the recessed portion 34 is moved due to frictional force. The first auxiliary guide wheel 40 is vertically pivoted above the etching chamber 10 , on one side corresponding to the center of the driving roller 30 , and arranged at a fixed distance. The second auxiliary guide wheels 50 are vertically pivoted above the etching chamber 10 , corresponding to the other side of the center of the driving roller 30 , and are staggered relative to the first auxiliary guide wheels 40 at a fixed distance. configuration, whereby the first auxiliary guide wheel 40 and the second auxiliary guide wheel 50 can sandwich the glass substrate 1, and when the glass substrate 1 is driven by the driving roller 30, it can assist in guiding the glass substrate 1 .
