Problems solved by technology

[0003] The existing wave soldering does not have an automatic tin-adding device, which requires personnel to manually add tin, and the process of manually putting the tin bar into the tin bath is likely to cause liquid tin sputtering, causing burns to personnel, and has a certain installation In addition, manual tin addition requires workers to regularly observe the liquid level of the tin bath to determine whether to add tin, which increases labor costs. At the same time, the liquid level meets the requirements when observed, but the liquid level of the tin bath decreases when it is not observed, so that Productivity is affected, and the height of the tin surface cannot be guaranteed, which directly affects the effect of tin soldering on the circuit board

Embodiment 1

[0031] Embodiment one, as Figure 1 to Figure 4 As shown, a wave soldering automatic tinning machine for a PON / IPTV router PCB board includes a welding machine body 1 and an automatic tinning mechanism 2. A wave soldering tin tank 3 is provided under the welding machine body 1, and the automatic tinning mechanism 2 is used. To add tin bars to the wave soldering tin tank 3, the automatic tin adding mechanism 2 includes a conveyor belt 4, which is arranged obliquely, and is used to transfer the tin bars placed at a low place to a high place, that is, higher than the height of the wave soldering tin tank 3, and the conveyor belt 4 One side of the tin bar is provided with a tin bar guide conveying device 7, and the tin bar is turned and the conveying height of the tin bar is lowered by the tin bar guide transport device 7, so that the tin bar falls into the wave soldering tin tank 3 to realize the automatic tin adding process, and at the same time reduce the The added height of th...

Embodiment 2

[0034] Embodiment two, such as Figure 6 As shown, the top of the bar-shaped housing 16 is provided with a tin bar cutting mechanism 17, and the tin bar cutting mechanism 17 is located between the arc-shaped steering housing 15 and the hollow transmission cylinder 9, and the tin bar cutting mechanism 17 is used to cut the tin bar short The tin bar cutting mechanism 17 includes a cutter cylinder 18, a rotating shaft 19, a bar cam 20, a knife seat 21 and a blade 22, and the cutter cylinder 18 is fixedly installed on the top of the bar housing 16, and the cutter cylinder 18 can be installed on the bar through a bracket. On the shaped housing 16, a rotary shaft 19 is provided for rotation in the cutter cylinder 18, and one end of the rotary shaft 19 is connected with a motor, and the motor is installed on one end of the cutter cylinder 18, and the bar cam 20 is fixedly sleeved on the rotary shaft 19, and the knife seat 21 is arranged in the cutter barrel 18, the bottom of the cutt...

Embodiment 3

[0035] Embodiment three, such as Figure 7 As shown, the liquid level detection mechanism 12 includes a floating bar 26 and a floating ball 27. One end of the floating bar 26 is slidably connected with the inner wall of the wave soldering tin bath 3, and the floating bar 26 slides along the height direction of the tin liquid surface. The other end of the floating bar 26 One end is fixed with a floating ball 27, the floating ball 27 is provided with a probe 28, the wave soldering tank 3 is provided with a liquid level lower limit probe 29 and a liquid level upper limit probe 30, a liquid level lower limit probe 29 and a liquid level upper limit probe 30 are located on the moving path of the probe 28; the sliding direction of the floating ball 27 is controlled by the floating bar 26, so that the floating ball 27 drives the probe 28 to slide up and down. The tin mechanism starts to automatically add tin. When the probe 28 contacts the liquid level upper limit probe 30, the automa...

Abstract

The invention discloses a wave soldering automatic tin adding machine for a PON / IPTV router PCB, the wave soldering automatic tin adding machine comprises a soldering machine body and an automatic tin adding mechanism, a wave soldering tin groove is arranged below the soldering machine body, and the automatic tin adding mechanism is used for adding tin bars into the wave soldering tin groove; the automatic tin adding mechanism comprises a conveying belt, the conveying belt is obliquely arranged, a tin bar guiding and conveying device is arranged on one side of the conveying belt, a plurality of bearing cross rods are arranged on a belt of the conveying belt in the conveying direction of the belt, and the ends, close to the tin bar guiding and conveying device, of the bearing cross rods are obliquely arranged and are lower than the other ends. The tin bar guiding and conveying device comprises a guiding shell and a hollow conveying cylinder, a notch communicated with the interior of the guiding shell is formed in the portion, close to the guiding shell, of the machine frame of the conveying belt, a sliding way only allowing a single tin bar to pass through is arranged in the guiding shell, and the hollow conveying cylinder is arranged under the discharging end of the guiding shell. Tin bars can be automatically conveyed and conveyed into the wave soldering tin groove, manual tin adding is avoided, and the labor cost is reduced.

Description

technical field [0001] The invention relates to the technical field of wave soldering, in particular to a wave soldering automatic tinning machine for PON / IPTV router PCB boards. Background technique [0002] Before the PCB board in the PON / IPTV router is installed and used, the surface of the PCB board needs to be tinned. In the current industry, wave soldering machines are often used for tinning the PCB board. Wave soldering refers to the melting of solder The material is sprayed by an electric pump or an electromagnetic pump to form the solder wave peak required by the design, and it can also be formed by injecting nitrogen gas into the solder pool, so that the printed board pre-installed with components passes through the solder wave peak to realize the soldering of components or pins. Soldering of mechanical and electrical connections to printed board lands. At present, wave soldering liquid tin forms a wave-like phenomenon, allowing the soldering surface of the plug-i...
