Smoke removal device of reflow soldering machine

Abstract

The invention provides a smoke removal device of a reflow soldering machine. The smoke removal device comprises a baffle plate which is arranged in an exhaust pipe and a gear shift device which is arranged outside the exhaust pipe, wherein the gear shift device comprises a fan-shaped gear device and a spring clamp matched with the fan-shaped gear device; a clamping groove is formed in the upper part of the fan-shaped gear device; a lower clamp of the spring clamp is connected with the baffle plate in the exhaust pipe through a fixed rod; an upper clamp of the spring clamp is connected with a gear rod and extends into the clamping groove of the fan-shaped gear device through a through hole in the lower clamp; when the spring clamp is pressed, the upper clamp drives the gear rod to exit from the clamping groove, and through rotatably screwing the spring clamp, the spring clamp drives, through the fixed rod, the baffle plate in the exhaust pipe to rotate, so as to change the exhaust area in the exhaust pipe and realize the aims of adjusting exhaustion and removing smoke; and when the spring clamp is loosed, the upper clamp pushes the gear rod to extend in the clamping groove to be clamped and positioned. The smoke removal device has the beneficial effect of realizing the adjustment of exhaustion amount during SMT smoke removal through connecting the gear shift device with the baffle plate in the exhaust pipe, and is reasonable in structure and convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of SMT production lines, and in particular relates to a smoke and dust removal device of a reflow soldering machine. Background technique [0002] SMT (Surface Mount Technology) is a circuit assembly technology that mounts non-lead or short-lead surface mount components on the surface of a printed circuit board or other substrate surface, and then solders and assembles them. The SMT production line includes printing machines, connecting stations, reflow soldering, etc. arranged in sequence. A large amount of smoke and dust will be generated during the reflow soldering process. Usually, a smoke exhaust device is installed above the reflow soldering equipment. This design plays a better role. Smoke and dust removal effect, but because the outlet of the reflow soldering machine is set on its end face, part of the smoke flows along the outlet to the production workshop during the production process, which affect...

Problems solved by technology

The SMT production line includes printing machines, connecting tables, reflow soldering, etc. arranged in sequence. A large amount of smoke and dust will be generated during the reflow soldering process. Usually, a smoke exhaust device is installed above the reflow soldering equipment. This design plays a better role. Smoke and dust removal effect, however, because the outlet of the reflow soldering machine is set on its end face, during the production process, part of the smoke flows along the outlet to the production workshop, which affects the quality of the product while polluting the production workshop and affecting the health of the operator healthy
