DETAILED DESCRIPTION

[0028] The core of the present invention is to provide a soldering flux replenishing device, which can realize automatic addition of soldering flux, has accurate control, low cost and good use effect.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Please refer to Figure 1 , Figure 1 This is a structural schematic diagram of a specific implementation of the flux replenishing device provided by the present invention.

[0031] In this embodiment, the flux replenishing device includes:

[0032] The coating tool 20 is used to carry the workpiece 1; that is, the workpiece 1 is placed on the coating tool 20, and the coating tool 20 can be placed on the supporting body;

[0033] The storage component 12 is used to store soldering flux and is sealed; the storage component 12 may be cylindrical, preferably a conical cylinder;

[0034] The movable assembly is used to support the storage component 12, and the storage component 12 can move longitudinally along with the movable assembly; the movable assembly changes the flux level inside the storage component 12 by pushing the storage component 12 upward, thereby facilitating material loading;

[0035] A connecting pipe 6, wherein a first end of the connecting pipe 6 is connected to the storage component 12 and a second end thereof is openable and closable, and the soldering flux can flow from the first end to the second end of the connecting pipe 6 according to the U-tube principle; specifically, the opening and closing of the second end of the connecting pipe 6 can be achieved by a valve;

[0036] The addition tube 2 and the flux addition valve 5 are connected at one end to the preset position of the connecting tube 6 via the flux addition valve 5, and the other end is suspended above the coating tool 20. After the flux addition valve 5 is opened, the flux in the connecting tube 6 can flow out of the flux addition valve 5 into the coating tool 20 under the action of gravity. Specifically, the volume of the connecting tube 6 between the preset position and the second end of the connecting tube 6 is equal to the volume of the single target addition amount of flux, which facilitates the control of the flux addition amount.

[0037] The controller is used to control the opening and closing of the flux adding valve 5 and the second end of the connecting pipe 6. Specifically, when it is detected that the workpiece 1 is placed in place, the flux adding valve 5 is controlled to open and the second end of the connecting pipe 6 is opened, while maintaining the airtightness of the storage component 12. At this time, the flux adding valve 5 and the second end of the connecting pipe 6 in the connecting pipe 6 are in a connected state, and the flux inside them will flow into the adding pipe 2 under the action of gravity, completing the discharge, that is, completing the flux replenishment process.

[0038] The flux replenishing device provided by the present invention utilizes the U-tube principle. As the storage component 12 moves upward, the flux can automatically flow to the second end of the connecting tube 6. Then, by opening the flux adding valve 5, the flux can automatically flow into the adding tube 2 under the action of gravity, and then flow onto the coating tooling 20, realizing the process of automatic loading and automatic discharging, with high control precision and convenient operation.

[0039] In some embodiments, a conducting valve 10 is further included. The conducting valve 10 is installed at the second end of the connecting pipe 6. The conducting valve 10 allows gas to enter along the second end of the connecting pipe 6 to facilitate discharge.

[0040] Preferably, the addition conduction valve 10 is a one-way valve, that is, only gas is allowed to enter the connecting pipe 6, and the gas or flux in the connecting pipe will not flow out of the addition conduction valve 10, ensuring reliability of use and low cost of the one-way valve.

[0041] In some embodiments, a support assembly is further included, and the storage unit 12 is mounted on the support assembly and is movable relative to the support assembly. Specifically, the support assembly includes a support rod 17, a slider 16, and a ball bearing 18 positioned between the support rod 17 and the slider 16. The storage unit 12 is fixed to the slider 16, and the slider 16 is movable along the extension direction of the support rod 17. Specifically, the movement between the slider 16 and the support rod 17 is facilitated by the ball bearing 18. The configuration of the support assembly can limit the movement direction of the storage unit 12 and provide a certain degree of support.

[0042] In some embodiments, an addition completion sensor 7 is further included. The installation height of the addition completion sensor 7 is the same as the installation height of the flux addition valve 5. The controller is also used to control the flux addition valve 5 to close after the addition completion sensor 7 senses that the addition of flux is complete. Specifically, the volume between the preset position in the connecting pipe 6 and the quantitative supply sensor 8 of the connecting pipe 6 is equal to the volume of the single target addition amount of the flux, thereby ensuring that the volume of the flux discharged each time is consistent. Preferably, the addition completion sensor 7 is a photoelectric switch, which determines whether there is still flux at the position of the addition completion sensor 7. When no flux is detected, that is, when the addition completion sensor 7 can receive a photoelectric signal, it means that the flux discharge is completed, and the controller can control the flux addition valve 5 to close.

[0043] In some embodiments, a workpiece sensor 3 is further included, and the workpiece sensor 3 is used to sense whether the workpiece 1 is placed on the coating tool 20; specifically, the workpiece sensor 3 can also be a photoelectric switch, or an in-position sensor.

[0044] In some embodiments, the moving assembly includes a power-assisting elastic component 13 and a power-assisting restraining component 15. The power-assisting elastic component 13 is a pre-compressed elastic component that pushes the storage component 12 upward. Once the storage component 12 is in place, the power-assisting restraining component 15 locks the power-assisting elastic component 13. Specifically, the pre-compression of the power-assisting elastic component 13 can be achieved by the weight of the storage component 12. This arrangement, by using the pre-compressed elastic component to push the storage component 12 upward, completes the automatic loading process, achieving unpowered drive and automatic flux replenishment, effectively simplifying the equipment and reducing costs.

[0045] The power-assist elastic component 13 is preferably a spring, and the power-assist restraint component 15 is a cylinder, which locks or unlocks the elastic component by extending or retracting the cylinder, or the power-assist restraint component 15 includes a push rod and a power-assist locking motor. After receiving the locking signal, the power-assist locking motor controls the push rod to move to engage with the elastic component to prevent the elastic component from continuing to move.

[0046] In some embodiments, a level-equalizing valve 9 and a quantitative replenishment sensor 8 are further included. The level-equalizing valve 9 is installed at the second end of the connecting pipe 6. The controller is also used to control the level-equalizing valve 9 to close after the quantitative replenishment sensor 8 senses that the flux loading is completed. For ease of control, the level-equalizing valve 9 is preferably an electrically controlled valve, such as a solenoid valve or an air-controlled valve. Preferably, the quantitative replenishment sensor 8 is a photoelectric switch to determine whether there is flux at the position of the quantitative replenishment sensor 8. When the quantitative replenishment sensor 8 detects the flux, that is, when the addition completion sensor 7 cannot receive the photoelectric signal, it means that the flux loading is completed, and the controller can control the level-equalizing valve 9 to close. Furthermore, the function of the addition conduction valve 10 can also be achieved with the help of the level-equalizing valve 9, that is, there is no need to set the addition conduction valve 10, but the discharge is achieved by opening and closing the level-equalizing valve 9.

[0047] Specifically, the storage component 12 is moved into position when the flux in the connecting tube 6 flows to the position of the quantitative replenishment sensor 8. The storage component 12 is then considered to be in position. Of course, the storage component 12 can also be controlled by controlling the fixed distance of upward movement. For example, each upward movement of the storage component 12 to a height H can be considered to be in position. When this method is used, the moving component can be a pneumatic cylinder or an electric cylinder, which directly drives the storage component 12 upward. The upward movement height H should not be too large, which will cause the flux to flow too quickly and hinder the detection of the quantitative replenishment sensor 8. It should be noted that any method that can assist the flux in flowing to the second end of the connecting tube 6 is not limited to the determination method given in this embodiment.

[0048] In some embodiments, a sealing cover 19 is further included, which is used to seal the storage component 12 to ensure the sealing of the storage component 12.

[0049] In some embodiments, a ventilation valve 11 is further included, which is installed on the top of the storage component 12; the controller is also used to control the ventilation valve 11 to open when loading is required. At this time, the liquid level valve 9 is also in the open state, and after the quantitative supply sensor 8 senses that the flux loading is completed, the ventilation valve 11 is controlled to close.

[0050] In a specific embodiment, the flux is stored in the storage component 12. When flux is added to the storage component 12, the assist elastic component 13 is compressed due to the action of gravity, and the storage component 12 is fixed on the slider 16. The slider 16 is connected to the support rod 17 through the ball 18, and the sealing cover 19 seals the storage component 12; when discharging is required, that is, when flux replenishment is required, the workpiece 1 is placed on the coating tool 20, and the workpiece sensor 3 senses that the workpiece 1 is in place, the flux adding valve 5 and the adding conduction valve 10 are opened, and the flux on the upper part of the flux adding valve 5 flows along the adding pipe 2 to the workpiece 1. When the addition is completed, the sensor 7 senses that there is no flux flowing, the flux adding valve 5 is closed, and the adding conduction valve 10 is closed. When loading is required, the ventilation valve 11 is opened, the level valve 9 is opened, the power-assisted locking motor is running, and the power-assisted restraint is popped open. Since one addition is completed, the weight of the flux becomes smaller, the power-assisted elastic component 13 stretches and moves, and the liquid level of the flux in the storage component 12 rises relatively. The storage component 12 and the connecting pipe 6 form the same liquid level due to the connecting principle. When the quantitative supply sensor 8 senses the flux, the level valve 9 is closed, the ventilation valve 11 is closed, the power-assisted locking motor stops running, the power-assisted restraint is reset, and it is again engaged with the power-assisted elastic component 13. For example, the end of the cylinder can be brought into contact with one end of the reset elastic component to constrain the power-assisted elastic component 13 to stop running, and the storage component 12 no longer moves up. Specifically, the workpiece sensor 3 and the flux adding valve 5 are fixed on the fixed column 4 to ensure stability.
