AI Technical Summary
Technical Problem
In existing tunnel-type nitrogen-filled lead-free wave soldering machines, electronic boards are easily damaged during transmission due to contact with gaps in the transmission chain.
Method used
An anti-fall component was designed, including a guide rail, a slider, a fixing rod, a support rod, a placement plate, and a sensor. The sensor senses the electronic board and drives the slider to move on the guide rail, causing the placement plate to move along with the electronic board to prevent it from falling.
Benefits of technology
This effectively prevents electronic boards from falling out of gaps in the transmission chain during transmission, avoiding damage and improving the safety and reliability of the equipment.

Abstract
The utility model discloses a tunnel type lead-free crest welder capable of charging nitrogen in the whole process, which comprises a welder assembly comprising a welder body, a fixing plate and a transmission chain. The anti-falling assembly comprises a guide rail, a sliding block, a fixing rod, a supporting rod, a placing plate and a sensor; the fixed rod is fixed between the opposite ends of the sliding blocks; the supporting rods are fixed on the two sides of the top end of the fixed rod; the placing plate is inserted into the top end of the supporting rod; and the sensor is embedded in the center of the top end of the placing plate. According to the conveying device, the anti-falling assembly is arranged, auxiliary protection can be carried out on the electronic board in the conveying process, meanwhile, due to the fact that the size of the containing plate is larger than that of the electronic board, the electronic board can rotate on the containing plate when being impacted, and therefore the electronic board is prevented from falling from a neutral position between conveying chains, and the electronic board is prevented from being damaged.
