The general direct employing scraper of traditional application type solar cell backboard coating method applies, have following defective: scraper acts directly on basement membrane, easy scratch basement membrane, very difficult control basement membrane both sides scraping makes its surface leave scratch, affect the performance of solar cell backboard, and coating easily flows down from the bottom, causes certain waste; In addition, generally can only adopt ratio of viscosities low coating material, if viscosity is too high, can make crawling even.
In view of this, the inventor studies this, develops specially a kind of solar cell backboard process units coating mechanism, and this case produces thus.
The utility model content
The purpose of this utility model is to provide a kind of scratch basement membrane, saving coating and simple in structure, easy to operate solar cell backboard process units coating mechanism of being difficult for.
To achieve these goals, solution of the present utility model is:
A kind of solar cell backboard process units coating mechanism, comprise support, dancer rools, main steel rider, band material steel rider, band hopper and the doctor roll etc. of being coated with, wherein, main steel rider, band material steel rider and the doctor roll of being coated with is arranged in order the upper end that is arranged on support, be arranged on the below of band material steel rider with hopper, comma scraper is installed on doctor roll, and between band material steel rider and doctor roll, dancer rools is arranged on the top of support.
The master is coated with steel rider and is fixedly mounted on support, is used for controlling stability and the flatness of basement membrane transmitting procedure.
Band material steel rider is movably arranged on support, can regulate distance between itself and doctor roll by the cylinder of driving mechanism, and band material steel rider bottom is positioned at the band hopper, can be with pigment transfer to basement membrane.
Doctor roll is movably arranged on support, can regulate it and be with the distance of expecting between steel rider by the cylinder of driving mechanism, the comma scraper of doctor roll can parallelly scrape unnecessary coating on band material steel rider, guarantee the uniformity that band material steel rider is coated, the coating that scrapes simultaneously can be reused, and saves material.
Above-mentioned dancer rools, the main two ends that are coated with steel rider, band material steel rider are respectively equipped with gear, and are rack-mount by gear, and it can freely be rotated.
During above-mentioned solar cell backboard process units coating mechanism work, under the driving of solar cell backboard process units driving mechanism, dancer rools, master are coated with steel rider, band material steel rider begins synchronous rotation, basement membrane is exported from dancer rools, walk around main being coated with bottom steel rider, pass the main gap that is coated with between steel rider and band material steel rider, then walk around the top of band material steel rider, be transferred to next mechanism.When basement membrane was walked around band material steel rider, its lower surface contacted with band material steel rider, and the coating on band material steel rider is coated on basement membrane uniformly, and the parallel unnecessary coating that scrapes on band material steel rider of comma scraper on doctor roll, guarantee the uniformity that band material steel rider is coated simultaneously.In addition, can also by accommodation zone material steel rider and the main distance that is coated with between steel rider, doctor roll, control the thickness of basement membrane coat.Adopt above-mentioned solar cell backboard process units coating mechanism to compare with traditional coating method, scraper does not directly contact with basement membrane, can accurately control the width of the face of being coated with, and the glossiness that is coated with face is good, even thickness, can guarantee the planarization of basement membrane; The comma scraper of doctor roll can parallelly scrape unnecessary coating on band material steel rider, recycling, easy to operate and sanitation and hygiene; Employing band material steel rider to basement membrane, is suitable for the coating of different viscosities with pigment transfer, and the dope viscosity scope that can adopt is wide.
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
