Embodiment 1

[0066]A kind of solder removal equipment for cleaning and recycling PCB boards, such as figure 1 As shown, it includes a bottom plate 1, a fixed frame 2, a hot blowing mechanism 4 and a flushing mechanism 5, the upper part of the bottom plate 1 is provided with a fixed frame 2, the front side of the bottom plate 1 is provided with a hot blowing mechanism 4, and the left side of the bottom plate 1 is provided with a flushing mechanism 5 .

[0067] When people need to remove the solder on the PCB board, they can use this solder removal equipment for cleaning and recycling the PCB board. First, people wear protective gloves, hold the PCB board with their hands at the center position above the base plate 1, and then manually push the heat sink backwards. The blowing mechanism 4 makes the hot blowing mechanism 4 melt the tin on the PCB board below, and letting go makes the hot blowing mechanism 4 reset forward, thereby driving the flushing mechanism 5 to move to the right to rinse ...

Embodiment 2

[0069] On the basis of Example 1, such as figure 2 and image 3 As shown, the hot blowing mechanism 4 includes a first guide sleeve 41, a heating and blowing assembly 42 and a first compression spring 43. The assembly 42 , a first compression spring 43 is connected between the heating and blowing assembly 42 and the first guide sleeve 41 , and the first compression spring 43 is wound on the heating and blowing assembly 42 .

[0070] People manually move the heating and blowing assembly 42 backwards, and the first compression spring 43 is compressed, which realizes the effect that the heating and blowing assembly 42 melts the solder on the PCB board. After the solder is melted, people let go of the first compression spring 43 Drive the heating and blowing assembly 42 to reset.

[0071] The flushing mechanism 5 includes a water tank 51, a second guide sleeve 52, a flushing nozzle assembly 53, a second compression spring 54, a third guide sleeve 55, a first elastic moving bloc...

Embodiment 3

[0074] On the basis of Example 2, such as Figure 4-7 As shown, a clamping mechanism 6 is also included, and the clamping mechanism 6 includes a cylinder 3, a support plate 61, a clamping block 62 and a third compression spring 63, the middle part of the bottom plate 1 is equipped with a cylinder 3, and the telescopic rod of the cylinder 3 is provided with The supporting plate 61 is provided with a sliding and symmetrical clamping block 62 on the supporting plate 61 , and a third compression spring 63 is connected between the clamping block 62 and the supporting plate 61 .

[0075] People manually move the clamping block 62 to the outside, the third compression spring 63 is compressed, and people put the PCB board on the clamping block 62, which realizes the effect of clamping the PCB board, and then starts the cylinder 3, and the telescopic rod of the cylinder 3 The support plate 61 is driven to reciprocate up and down, so that the clamping block 62 drives the PCB board to re...

Abstract

The invention relates to removing equipment, in particular to tin soldering removing equipment for PCB cleaning and recycling. According to the tin soldering removing equipment for PCB cleaning and recycling, the two hands are liberated, and the working efficiency is improved. The tin soldering removing device for PCB cleaning and recycling comprises a fixing frame, a hot air blowing mechanism and a flushing mechanism, and the fixing frame is arranged on the upper portion of a bottom plate; the hot air blowing mechanism is arranged on the bottom plate; and the flushing mechanism is arranged on the bottom plate. According to the tin soldering removing equipment, a heating and blowing assembly is manually moved backwards by people, a first compression spring is compressed, and the effect that tin soldering on a PCB is melted through the heating and blowing assembly is achieved; and clamping blocks are manually moved towards the outer side, third compression springs are compressed, people place the PCB on the clamping blocks, and the effect of clamping the PCB is achieved.

Description

technical field [0001] The invention relates to a cleaning device, in particular to a solder cleaning device for cleaning and recycling PCB boards. Background technique [0002] The Chinese name of PCB is printed circuit board, also known as printed circuit board. It is an important electronic component, a support for electronic components, and a carrier for electrical connections of electronic components. PCB circuit boards will be recycled after use. Utilization, the current recycling method for waste PCB circuit boards is to refurbish the reusable PCB circuit boards, and then put them on the market as refurbished parts for reuse. Electronic components that cannot be reused are installed with new electronic components. The existing cleaning methods mostly use manual tin furnaces to clean the solder on the waste PCB circuit board. This method needs to be cleaned back and forth many times, which belongs to Manual labor consumes people's precious time, and people need to man...
