Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of dust removal, in particular to a dust removal device and a conveying device comprising the same. BACKGROUND
[0002] The solar cell copper electroplating production line process includes incoming yellow film cell piece-coating-printing-developing-edge wrapping-electroplating and the like. The role of the printing process is to change the properties of the photosensitive glue on the surface of the cell piece with the photosensitive glue film after coating through light source irradiation. The printing process uses exposure, collimated light transmits through the mask plate and uniformly irradiates the surface of the coated photosensitive glue substrate, the photosensitive area absorbs light to cause cross-linking reaction of the photoinitiator and monomer with the acrylic resin, thereby being insoluble in the developing solution. At the same time, the MASK plate with patterns is used to shield the light source, and the non-photosensitive area of the shielding part is dissolved in the developing solution after development, thereby forming the patterns required for subsequent electroplating. When the light source transmits through the MASK to expose the underlying cell piece, the pattern area on the MASK can prevent the light source from irradiating the surface of the cell piece, and the photosensitive glue in the non-shading area will change its properties after being irradiated by the light source. In the subsequent development process, the photosensitive glue that has not undergone cross-linking reaction will be washed away, and the copper film at the bottom layer will be exposed, thereby achieving the purpose of slotting, and the copper grid line can be grown in the subsequent recess.
[0003] However, in the actual production process, due to the poor cleanliness of the workshop, the cell piece conveyed after coating will carry some dust particles on the surface when transported to the printing process, which will cause the dust particles on the surface of the cell piece to easily stick to the MASK plate during the printing process, thereby interfering with the irradiation of the printing light source and causing subsequent batch printing contamination.

[0031] In the conventional technology, before the battery piece is printed and fed, the cleanliness of the battery piece in the flower basket needs to be checked manually, and the battery piece is blown by using an air gun to remove the dust on the surface of the battery piece. Not only is dust likely to remain during the blowing process, but also the battery piece and the flower basket are likely to collide during the blowing and dust removal process, thereby causing damage to the battery piece and causing printing defects, which affects the performance of the battery piece.
[0032] Based on this, the first aspect of the present application provides a dust removal device, as shown in Figure 1 The dust removal device 100 includes a slide rack 110 and a dust removal mechanism.
[0033] The slide rack 110 is used to stack the slide bodies at intervals; the dust removal mechanism includes a baffle 120 arranged on the side surface of the slide rack 110, a driver 130 and a gas source, as shown in Figure 2As shown, the baffle 120 is provided with a plurality of air holes 121, and the driver 130 is connected with the baffle 120, and the driver 130 is used to drive the baffle 120 to move towards the slide in the slide rack 110, and the baffle 120 is used to limit the slide in the slide rack 110, and the plurality of air holes 121 are respectively connected with the gas source to blow air to the slide in the slide rack 110.
[0034] The baffle 120 in the dust removal mechanism is used to limit the slide in the slide rack 110, and the air holes 121 provided on the baffle 120 are used to blow air to the slide, which can not only remove the dust particles on the surface of the slide, but also limit the slide to avoid damage caused by the collision between the slide and the slide rack 110 during the blowing and dust removal process. The dust removal device 100 improves the surface cleanliness of the slide.
[0035] It can be understood that the opening position of the air hole 121 can be adjusted according to the placement position of the slide. In some embodiments, the opening position of the air hole 121 corresponds to the position of the slide in the slide rack 110, and the air hole 121 is used to blow air to the cross section of the slide.
