During this process, in order to improve soldering efficiency and quality, some high-temperature flux is usually added to the solder paste. However, the flux in the solder paste will volatilize due to the high temperature in the furnace. During the long-term use of the reflow soldering equipment, the gaseous flux in the furnace chamber is likely to condense to form oily substances or flocs. The condensed matter drips onto the product board, greatly affecting its quality. Therefore, it is usually equipped with a flux cooling and recovery device.

The first recycling box 14 is in an inclined state, and multiple discharge scrapers 52 rotate, so as to facilitate pushing the flux toward a position close to the connection box 13.

[0032] like Figures 1 to 8As shown, the filter recovery assembly 6 includes a mounting shaft 61, and a first disc 611 and a second disc 612 are coaxially mounted on both ends of the mounting shaft 61. The first disc 611 is composed of two first solid plates 6111 with a central angle of 90 degrees and two first filter plates 6112 with a central angle of 90 degrees. The first solid plate 6111 and the first filter plate 6112 are spaced apart. The second disc 612 is composed of two second solid plates 6121 with a central angle of 90 degrees and two second filter plates 6122 with a central angle of 90 degrees. The second filter plate 6122 is composed of two second filter plates 6121 and the second filter plate 6122. The second solid plate 6121 corresponds to the first filter plate 6112. The second filter plate 6122 corresponds to the first solid plate 6111. Two first blocking plates 62 are coaxially mounted on the first disc 611. The two first blocking plates 62 are 90 degrees apart. Two second blocking plates 63 are coaxially mounted on the second disc 612. The two second blocking plates 63 are spaced 90 degrees apart. 90 degrees, and the second blocking plate 63 is opposite to the first blocking plate 62, a support frame 64 is fixedly installed on the connection box 13, a driving dial 641 and a driven groove wheel 642 are rotatably installed on the support frame 64, the round pin on the driving dial 641 is slidably installed in the radial groove of the driven groove wheel 642, a power shaft 65 is rotatably installed on the support frame 64, a first driven bevel gear 652 is coaxially installed on the top of the power shaft 65, and the first driving bevel gear 65 is coaxially installed on the reciprocating screw 74 1. The first driving bevel gear 651 meshes with the first driven bevel gear 652. A second driving bevel gear 653 is coaxially provided on the power shaft 65. A second driven bevel gear 66 is coaxially mounted on the driving dial 641. The second driven bevel gear 66 meshes with the second driving bevel gear 653. A third driving bevel gear 67 is coaxially mounted on the driven sheave 642. A third driven bevel gear 68 is coaxially mounted on the mounting shaft 61. The third driving bevel gear 67 meshes with the third driven bevel gear 68.When in use, the reciprocating screw 74 will drive the first driving bevel gear 651 to rotate synchronously during its rotation, and the power shaft 65 will be driven to rotate synchronously during its rotation. The power shaft 65 will drive the second driving bevel gear 653 to rotate during its rotation, and the second driving bevel gear 653 will drive the second driven bevel gear 66 to rotate during its rotation. The second driven bevel gear 66 will drive the driving dial 641 to rotate during its rotation, and the driven groove wheel 642 will be driven to rotate intermittently during its rotation. The driven groove wheel 642 will drive the third driving bevel gear 67 to rotate during its rotation, and the third driving bevel gear 67 will drive the third driven bevel gear 68 to rotate during its rotation. This will drive the mounting shaft 61 to rotate, and during this rotation, the first and second blocking plates 62 and 63 will be driven to rotate synchronously. When the first blocking plate 62 rotates to the first filter plate 6112, the second blocking plate 63 will rotate to the second solid plate 6121. When the first blocking plate 62 moves from the first filter plate 6112 toward the first solid plate 6111, the second blocking plate 63 will move toward a position close to the second filter plate 6122, thereby increasing the time the flux vapor stays in the first and second recovery boxes 14 and 15, and increasing the time the flux vapor stays between the first and second discs 611 and 612, so that as much flux vapor as possible condenses in the recovery boxes, improving the recovery effect.

[0033] like Figures 1 to 8 As shown, the first recovery plate 411, the second recovery plate 412, the third recovery plate 421 and the fourth recovery plate 422 have the same structure. The interior of the first recovery plate 411 is hollow. A condenser tube 8 is installed inside the first recovery plate 411. The condenser tube 8 is serpentine-shaped and wound around the interior of the first recovery plate 411. Both ends of the condenser tube 8 are respectively connected to the air heat exchanger. The air heat exchanger is a prior art fin type. Therefore, in this embodiment, the specific composition of the air heat exchanger is not described in detail. A cooling medium is introduced into the condenser tube 8 to improve the cooling effect of the first recovery plate 411 on the flux vapor. In this embodiment, the cooling medium adopts a cold Cooling water or refrigerant can be used. In order to increase the flow rate of the cooling medium, a booster pump can also be installed; the condenser 8 will be able to quickly reduce the temperature of the first recovery plate 411, the second recovery plate 412, the third recovery plate 421 and the fourth recovery plate 422, thereby improving the cooling efficiency of the flux vapor condensed on the surface of the first recovery plate 411, the second recovery plate 412, the third recovery plate 421 and the fourth recovery plate 422, and to a certain extent avoid the situation where the first recovery plate 411, the second recovery plate 412, the third recovery plate 421 and the fourth recovery plate 422 cannot condense the flux well due to their own high temperature after working for a long time.

[0034] like Figures 1 to 8 As shown, the filter assembly 2 includes a filter cone 21, a collection tank 22 and a first drive motor 23. The filter cone 21 is hollow and has a plurality of filter holes evenly opened on it. One end of the filter cone 21 is fixedly mounted on the collection cover 1. In this embodiment, the end with a larger diameter of the filter cone 21 is connected to the collection cover 1, and the collection tank 22 is threadedly mounted on the bottom of the filter cone 21, that is, the collection tank 22 and the filter cone 21 are detachably connected. The first drive motor 23 is mounted inside the filter cone 21, and a scraper 24 is mounted on the output shaft of the first drive motor 23. The scraper 24 is in contact with the inner wall of the filter cone 21 and is located on the collection cover 1 and inside the filter cone 21. A second fan 16 is installed on the inside; when in use, the second fan 16 is started, and the second fan 16 is an axial flow fan, so as to improve the effect of pumping the flux into the first recovery box 14, and the filtering cone 21 is used to filter the air to prevent other particles except the flux vapor from entering the first recovery box 14; when the flux passes through the filtering cone 21, part of the flux vapor may condense on the filtering cone 21, and the first drive motor 23 is started. During the rotation of the first drive motor 23, the scraper 24 is driven to move, and the scraper 24 will scrape the flux on the filtering cone 21, so that the flux vapor can pass smoothly and enter the interior of the first recovery box 14, so as to facilitate the recovery of the flux vapor.

[0035] like Figures 1 to 8 As shown, the heating assembly 3 includes a heating wire 31 and an insulation sleeve 32. The heating wire 31 is wound around the outer wall of the delivery pipe 11, and the insulation sleeve 32 is coaxially sleeved on the outer wall of the delivery pipe 11; during welding, the flux volatilizes, and then enters the collection cover 1 and passes through the delivery pipe 11 into the first recovery box 14 for recycling. Since the delivery pipe 11 has a certain length, during use, the flux may solidify on the inner wall of the delivery pipe 11 due to the temperature drop, thereby affecting the recovery of the flux. Therefore, when in use, the heating wire 31 is energized. The energized heating wire 31 will emit heat, thereby heating the delivery pipe 11, so that the flux is not easy to condense at the position of the delivery pipe 11. The insulation sleeve 32 can slow down the loss of heat and play an energy-saving role. When in use, a temperature sensor is installed on the wall of the delivery pipe 11. When the temperature reaches the specified temperature, the continued power to the heating wire 31 is cut off.

[0036] like Figures 1 to 8As shown, two crushing rollers 9 are rotatably installed at the bottom of the connecting box 13, and the two crushing rollers 9 are meshed with each other. A fourth driven bevel gear 92 is coaxially installed at one end of one of the crushing rollers 9, and a fourth driving bevel gear 91 is coaxially installed on the power shaft 65, and the fourth driven bevel gear 92 is meshed with the fourth driving bevel gear 91; when in use, the flux collected and condensed by the recovery self-cleaning component 4 and the filter recovery component 6 will fall into the connecting box 13, and the rotation of the power shaft 65 will drive the fourth driving bevel gear 91 to rotate synchronously, and the rotation of the fourth driving bevel gear 91 will drive the fourth driven bevel gear 92 to rotate, and the rotation of the fourth driven bevel gear 92 will drive the crushing roller 9 to rotate, and the rotation of the crushing roller 9 will drive the other crushing roller 9 to rotate through the transmission gear 53. The two crushing rollers 9 will crush the recovered flux during their rotation, thereby facilitating the subsequent recycling of the flux.

[0037] like Figures 1 to 8 As shown, a collecting box 131 for collecting the flux in the first recycling box 14 and the second recycling box 15 is slidably installed at the bottom of the connecting box 13, and a handle 132 is fixedly installed on the collecting box 131; when in use, when a large amount of recycled flux is loaded inside the collecting box 131, the staff holds the handle 132 and then pulls it, thereby facilitating the separation of the collecting box 131 from the connecting box 13, thereby facilitating the unified treatment of the recycled flux.

[0038] The implementation principle of this embodiment is: start the first fan 12, and the air in the second recovery box 15 is discharged during the rotation of the first fan 12, so that the air mixed with flux enters the first recovery box 14 through the collection cover 1, and the recovery self-cleaning component 4 can condense and recover the flux vapor and then scrape off the condensed flux, thereby maintaining its own recovery effect. The flux recovered and cleaned by the recovery self-cleaning component 4 will move along the inclined surface of the first recovery box 14 toward the position close to the connecting box 13, thereby facilitating the collection of the flux. The filtering recovery component 6 located at the position of the connecting box 13 will improve the recovery effect of the flux vapor, and can slow down the flow speed of the flux vapor in the first recovery box 14 and the second recovery box 15, and increase its residence time in the first recovery box 14 and the second recovery box 15, so that it can be condensed and recovered as much as possible.
