Energy-saving and environment-friendly efficient tin brushing device for television mainboard

Abstract

The invention relates to the technical field of television production, and discloses an energy-saving and environment-friendly efficient tin brushing device for a television mainboard. The device comprises a turntable, the outer wall of the turntable is fixedly connected with a tin brushing bin, the interior of the tin brushing bin is movably connected with a driving disc, the outer wall of the driving disc is movably connected with a rack, and the outer wall of the rack is engaged with a transmission gear. According to the energy-saving and environment-friendly efficient tin brushing device for the television mainboard, a transmission disc coaxial with a tin coating gear rotates to drive a tin cleaning gear to rotate so as to drive a screw rod to rotate, the tin coating gear rolls tin mudinto tooth seams during rotation, and the tin mud is pulled down by the screw rod to fall into a tin storage groove when rotating to the meshing position of the tin coating gear and the screw rod; and the tin mud is uniformly dispersed on the outer wall and the inner wall of a tin brushing plate while the tin brushing plate slides, so that the situation of tin leakage during tin brushing of the television mainboard is avoided, the tin coating quality of the television mainboard is improved, the defective rate is reduced, and the television mainboard tin brushing device is more energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of TV production, in particular to an energy-saving and environment-friendly high-efficiency tin brushing device for TV main boards. Background technique [0002] Similar to movies, TV uses the visual residual effect of the human eye to display a frame-by-frame gradient still image to form a visually moving image. The sending end of the TV system converts each tiny part of the scene into an electrical signal according to brightness and chromaticity Sequential transmission, and then display the brightness and chromaticity of each tiny part according to the corresponding geometric position at the receiving end to reproduce the entire original image. [0003] In order to meet market demand and reduce production costs, the tinning process of TV main boards is also performed by machines instead of manual batch operations. The existing tinning devices on TV main boards have the following problems: 1. The tin mud h...
