Description

Technical Field

[0001] The invention relates to the field of glass manufacturing, in particular to an adjustable glass printing screen inspection frame. Background Art

[0002] The screen is an auxiliary tool used for glass printing, which is divided into ink printing screen and silver paste printing screen. It is used to print black lace, trademarks and heating wires on glass.

[0003] The quality of glass printing determines the appearance and performance of the product. Therefore, the inspection of glass printing screen is particularly important. If the screen defects cannot be detected, it will lead to poor product appearance, broken heating wires and other defects, which will greatly affect the performance of the glass, causing the glass to be scrapped and unusable, and reduce the product yield. Therefore, the role of the screen inspection rack is particularly important.

[0004] Compared with this inspection table, the disadvantages of the original inspection stand are: when inspecting the bottom edge of the screen, the employee needs to bend down to inspect, and the top edge of the large screen cannot be inspected because it is too high and not at the same level as the human eye. In addition, the beam supporting the screen is a fixed beam, and the overlap between the screen pattern and the fixed beam blocks the inspection light, which is easy to cause missed inspection. Therefore, it is necessary to design an adjustable glass printing screen inspection stand. Summary of the invention

[0055] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right" and the like are used in the embodiments to illustrate the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "on" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0056] Furthermore, relational terms such as “first” and “second” and the like are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any such actual relationship or order between these components.

[0057] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
