Problems solved by technology

However, due to the geometry of the scraping block 14, when the cleaning agent is sprayed on the scraping block 14, the cleaning agent will be lost rapidly and cannot fully clean the scraping block 14, thus leaving gel on the scraping block 14, resulting in poor scraping

Embodiment Construction

[0033] In order to have a further understanding and understanding of the structural features and the achieved effects of the present invention, a preferred embodiment and accompanying drawings will be described in detail, as follows:

[0034] The invention relates to a scraping structure of a nozzle scraping machine, which improves the scraping effect of scraping coating material and gel remaining on the outside of a nozzle through a scraping piece and a scraping block. Moreover, the invention reduces the abrasion caused by scraping off the gel by the scraper block through the scraper sheet, thereby prolonging the service life of the scraper block.

[0035] see Figure 3A and Figure 3B , which are respectively a perspective view and a front view of a scraping structure in a preferred embodiment of the present invention; as shown in the figure, the scraping structure 30 of the present invention includes a base 32, a scraping block 34 and a scraping sheet 36 . The base 32 is...

Abstract

The scraping structure of a nozzle scraper comprises a substrate, a scraping block and a scraping blade, with the scraping block inside the substrate and having a scraping slot, the scraping blade at the front of the scraping block to increase the scraping area of the gel left on the nozzle. It can effectively improve the scraping effect, avoiding the impact to processing quality due to left gel on the nozzle, to improve the production qualification rate, reduce consumption to the scraping block and extend the durability of the scraping block.

Description

technical field [0001] The invention relates to a nozzle scraper, in particular to a scraper structure of the nozzle scraper. Background technique [0002] Currently, most industrial productions have coating processes to coat a coating material on a substrate, such as mask processes in optical disk processing and semiconductor processing. The coating process is to use a coating machine to spray the coating material to the substrate through a nozzle, so as to coat the coating material on the substrate. Taking the masking process as an example, the photoresist is coated on the substrate through the nozzle of the coater to form a mask on the substrate. When the nozzle of the coater sprays the coating material onto the substrate, the coating material remains outside the nozzle outlet and gradually forms crystals, ie, gel, over time. Since the coating machine will generate force during the coating process, such as the force generated by the spraying of the coating material from...
