Description

Technical Field

[0001] The utility model relates to the technical field of screen printing, in particular to a new photovoltaic cell screen printing device. Background Art

[0002] Screen printing refers to the process of using a screen as a base and making a screen printing plate with images and texts through a photosensitive plate-making method. Screen printing can adapt to various types of slurries, has a soft plate surface, can adapt to substrates of different hardness and softness, and is not limited by the surface shape and area size of the substrate. Therefore, it is widely used in electronic products, fabrics, plastics, metals, ceramics and glass products.

[0003] Most of the existing printing equipment is a single table, which can only print one battery substrate at a time. Multiple devices need to be used in series. This will increase the footprint of the device, which is not conducive to factory printing. At the same time, since the paint sprayed on the screen is generally more, it is convenient for printing, but too much paint is easily condensed on the placement board for a long time, resulting in waste of paint and increasing the cost of work. Therefore, in order to solve the above problems, we need to design a new photovoltaic cell screen printing equipment. Utility Model Content

The third gear 220d is fixedly connected to the rotating rod 210d, and the third gear 220d is rotatably connected to the tooth groove 220c.

[0036] Specifically, when the second motor 210a works, the rotating rod 210d rotates, and through the third gear 220d and the tooth groove 220c, the rotating plate 220a can drive the scraper 220b to rotate, so that when the battery substrate moves to the bottom of the placement plate 202, it can be printed. Furthermore, since the second motor 210a drives the rotating plate 220a to work continuously, it can drive the scraper 220b to rotate. When the paint is covered on the screen 202b for printing, the scraper 220b can bring the paint to the drain groove 202c and return the paint to the paint box, thereby avoiding the conveyor belt being placed on the placement plate 202, causing the paint to condense, affecting the printing work, and causing waste of paint.
