Technical Field

Background
The screen printer is a machine using a screen plate Shi Yin, and belongs to a printing machine. Screen printers are machines that print text and images, and are a generic term for machines or equipment used to produce printed matter. The silk screen printer belongs to a representative printing device in the stencil printer, and the silk screen can be made of nylon wires, copper wires, steel wires or stainless steel wires besides silk. The screen printing machine can be classified into a flat screen printing machine, a curved screen printing machine, a rotary screen printing machine, and the like.
In the photovoltaic industry, screen printing is mainly applied to electrode forming of batteries, and printing is performed by utilizing the basic principle that a part of mesh of a screen pattern is permeable to slurry and a part of mesh of a non-image-text is impermeable to slurry. The paste is poured into one end of the screen during printing, and a certain pressure is applied to the paste part of the screen by a scraper, and the screen moves towards the other end of the screen. The slurry is pressed from the mesh of the pattern portion onto the substrate by the squeegee while being moved. The scraper is always in line contact with the screen printing plate and the printing stock in the printing process, the contact line moves along with the movement of the scraper, and other parts of the screen are in a separation state with the printing stock, so that the printing dimensional accuracy is ensured, and the smearing of the printing stock is avoided. When the scraper scrapes the whole printing area, the screen is lifted, the screen is separated from the substrate, the ink is scraped back to the initial position by the ink returning knife, and the workbench returns to the feeding position, so that a complete printing stroke is achieved.
The existing screen printer is used for transferring and placing the silicon wafer into an independent drying box after the printing ink is printed on the silicon wafer, so that the printing ink is dried by the heat emitted by an infrared lamp, the independent drying box is used for drying the silicon wafer after the electrode is printed, the printing processing steps of the silicon wafer with the battery electrode are increased, and the overall processing efficiency of the battery electrode is lower. Therefore, we propose a solar photovoltaic screen printer drying tool to solve the above technical problems.

In actual operation, the electric heating pipe 25 of the drying assembly can dry the printed silicon wafer conveyed by the conveying mechanism 2, so as to promote the oil film printed on the electrode silicon wafer to be dried quickly.
Referring to fig. 2-3, in this embodiment, each sealing assembly 18 includes a set of screw rods 1804, a set of shaft sleeves 1805, a set of stepping motors 1801, a set of lifting blocks 1802 and a sealing door 1803, the two shaft sleeves 1805 are symmetrically and fixedly installed at two sides of the inlet 20 or the outlet 21, the two stepping motors 1801 are symmetrically installed right above the two shaft sleeves 1805, a screw rod 1804 is respectively and rotatably connected in the two shaft sleeves 1805, the top end of each screw rod 1804 is respectively connected with the output end at the bottom of the corresponding side stepping motor 1801, the two lifting blocks 1802 are respectively and threadedly connected to the periphery of the corresponding side screw rod 1804, and two ends at the top of the sealing door 1803 are respectively and fixedly connected with the two lifting blocks 1802 through a hanging block.

In the actual working process, the sealing assembly 18 at the back side of the working box 3 defaults to an initial state of sealing the outlet 21, the printed silicon wafer is pushed to the front end of the conveying mechanism 2 by the discharging mechanism of the screen printer, after that, when the conveying mechanism 2 conveys the printed silicon wafer to the inlet 20 at the front side of the working box 3, the two photoelectric switches 1806 at the inlet 20 sense the silicon wafer simultaneously and convey signals to the controller 32 to control the sealing assembly 18 at the front side of the working box 3 to work, at the moment, the group of stepping motors 1801 of the sealing assembly 18 at the front side drive the group of screw rods 1804 to rotate forward to drive the group of lifting blocks 1802 to drive the sealing doors 1803 to move upwards, and then the ascending sealing doors 1803 are far away from the inlet 20 at the front side of the working box 3, so that the inlet 20 is in an open state, so that the conveying mechanism 2 conveys the printed silicon wafer into the working box 3, after a period of time (for example, after 2 s), the controller 32 controls the sealing assembly 18 on the front side of the working box 3 to work again, at this time, a group of stepping motors 1801 of the front sealing assembly 18 drive a group of screw rods 1804 to rotate reversely so as to drive a group of lifting blocks 1802 to drive the sealing doors 1803 to move downwards, and then the descending sealing doors 1803 cover the front side of the inlet 20, so that the whole working box 3 is in a relatively closed state, and the conveying mechanism 2 stops conveying the electrode silicon wafer at this time (so as to maintain the electrode silicon wafer in the working box 3 in the drying process), so that the drying assembly dries an oil film on the surface of the electrode silicon wafer, and because the working box 3 is in a closed state, waste gas is prevented from overflowing from the inlet 20 and the outlet 21 of the working box 3;
after a period of time (for example, the drying time of the electrode silicon wafer is 30 s), the controller 32 controls the sealing assembly 18 at the rear side of the working box 3 to work, at this time, the sealing assembly 18 at the rear side drives the group of screw rods 1804 to rotate forward to drive the group of lifting blocks 1802 to drive the sealing door 1803 to move upwards, and then the ascending sealing door 1803 is far away from the outlet 21 at the front side of the working box 3, so that the outlet 21 is in an opened state, so that the conveying mechanism 2 can convey the silicon wafer after drying ink in the working box 3 to the tail end of the silicon wafer, and a processing staff can take the silicon wafer for subsequent processing;
when two photoelectric switches 1806 at the rear side of the working box 3 sense the silicon wafers output backwards at the same time, signals are transmitted to the controller 32 to control the sealing assembly 18 at the rear side of the working box 3 to work, at this time, a group of stepping motors 1801 of the sealing assembly 18 at the rear side drive a group of screw rods 1804 to reversely rotate to drive a group of lifting blocks 1802 to drive the sealing doors 1803 to move downwards, and then the descending sealing doors 1803 cover the front side of the outlet 21, so that the sealing assembly 18 at the rear side of the working box 3 is restored to the initial state, and the next electrode silicon wafer drying operation is facilitated.
