Description

Technical Field

[0001] This invention relates to the field of flux dispensing technology, and in particular to a flux dispensing device and dispensing method. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] Flux is typically a mixture with rosin as its main component. It is an auxiliary material that ensures smooth soldering. Flux is an auxiliary material used in electronic assembly soldering. Its main function is to remove oxides from the surface of the solder and the base material being soldered, preventing re-oxidation of the material surface during soldering, reducing the surface tension of the solder, and improving soldering performance. Flux is usually poured into a flux container on the bottom of some equipment. During soldering, the soldering rod or iron is first dipped in flux from the equipment's flux container before the soldering operation to ensure sufficient lubrication and protection of the soldering area. As the flux in the equipment's flux container is used, new flux needs to be added. The current method is usually to remove the equipment's flux container from the bottom, place a funnel at the opening of the flux container, and pour the flux from the flux container into the equipment's flux container through the funnel. However, the flux container is quite heavy, and one or two workers need to lift the heavy flux container to add flux, which is time-consuming, labor-intensive, and inefficient. Moreover, there is a risk of accidental flux leakage during the addition process. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a flux dispensing device that facilitates the addition of flux, has high dispensing efficiency, and effectively reduces flux waste.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: A flux dispensing device includes a connecting component that can be sealed to the top opening of a flux container. A first tube and a second tube pass through the connecting component and enter the flux container. The first tube is longer than the second tube. One end of the first tube extends to the bottom of the flux in the flux container, and the other end of the first tube can enter the flux container of the equipment. One end of the second tube is positioned above the flux in the flux container, and the other end of the second tube is connected to an air injection component. The air injection component injects gas into the flux container through the second tube, and the gas pushes the flux in the flux container through the first tube into the flux container of the equipment.

[0006] In the flux dispensing device described above, the sleeve component protrudes downward and outward toward the lower edge of the flux container to form a sealed connection with the top opening of the flux container, thus preventing air leakage.

[0007] In the flux dispensing device described above, the lower edge of the sleeve component facing the flux container has a corrugated structure, which facilitates the detachable connection of the sleeve component with the flux container.

[0008] As described above, in a flux dispensing device, the sleeve component is a sleeve cap, which is made of an elastic material so that the sleeve component can be fitted onto the opening of the flux container and provide a sealing function, and is also easy to remove. The socket component, the first tube, and the second tube are an integral structural component, or the first tube and the second tube are movable relative to the socket component.

[0009] As described above, in a flux dispensing device, the first tube has a circumferential protrusion on one side outside the flux container to engage with the opening of the equipment flux container, ensuring the reliability of the connection between the first tube and the equipment flux container and preventing the first tube from falling off the equipment flux container.

[0010] In another embodiment of the flux dispensing device described above, a snap-fit ​​plate is circumferentially arranged on one side of the first tube outside the flux container, with the snap-fit ​​plate spaced apart from the end of the first tube, and the snap-fit ​​plate can be detachably connected to a fixing rod on the side of the flux container opening of the device.

[0011] As described above, in a flux dispensing device, the first tube and the second tube are respectively equipped with flow meters, the flow meters are connected to a controller, the controller is connected to the air pumping component, and the controller controls the air pumping component to close based on the data transmitted by the flow meters.

[0012] The flux dispensing device described above further includes a movable vehicle body, which supports the flux container and a limiting part. The limiting part limits the flux container, and the movement of the movable vehicle body can move the flux container. When the volume of a single flux canister is small, the mobile vehicle is equipped with multiple support layers. By supporting the flux canister or the air-inflating component through the support layers or the mobile vehicle, the multiple flux canisters can be supported separately, and the multiple flux canisters can be supported uniformly.

[0013] In the flux dispensing device described above, the air pumping component is either a manual air pumping component or an automatic air pump.

[0014] Secondly, the present invention also provides a method for adding flux to equipment, including the aforementioned flux adding device, comprising the following: Move the flux bucket to the side of the equipment's flux container and open the top opening of the flux bucket; Open the equipment flux container; The fitting is placed over the top opening of the flux container, allowing the first and second tubes to enter the flux container. One end of the first tube extends to the bottom of the flux in the flux container, and the other end of the first tube enters the flux container of the equipment. One end of the second tube is positioned above the flux in the flux container, and the other end of the second tube is connected to the air-inflating component. The air-injection component injects gas into the flux tank through the second pipe, and the gas pushes the flux in the flux tank through the first pipe into the equipment's flux container.

[0015] The beneficial effects of the present invention are as follows: 1) The socket component provided by the present invention can be sealed to the top opening of the flux tank. The socket component is provided with a first pipe and a second pipe. The second pipe is connected to an air-inflating component. The first pipe connects the flux tank and the equipment flux container. The air-inflating component introduces gas into the flux tank, increasing the gas pressure in the flux tank. As a result, liquid is injected into the equipment flux container through the second pipe. There is no need to use a funnel to assist in pouring the flux, nor is it necessary for multiple people to lift the flux tank. This saves time and effort and effectively avoids leakage problems during the flux filling process.

[0016] 2) The sleeve component in this invention is reasonably designed. The lower edge of the sleeve component protrudes downward and outward to wrap around the flux container from the outside, which can seal the connection with the flux container. It can also ensure that the sleeve component has a certain elasticity, making it easy to fit the sleeve component onto the wall of the opening of the flux container, and can also ensure the sealing and stability during the working process.

[0017] 3) In this invention, the first tube is snapped into the equipment flux container by the protrusion to ensure a reliable connection between the first tube and the equipment flux container, or the first tube is detachably connected to the fixing rod on the opening side of the flux container by the snap-fit ​​plate to ensure a stable and reliable connection between the first tube and the equipment flux container. During the flux injection process, the stability of the first tube is ensured, and there is no need for external manual pressing of the first tube.

[0018] 4) The present invention is provided with a mobile vehicle body that supports flux containers. The movement of the mobile vehicle body drives the movement of the flux containers, which facilitates the movement of flux containers on site. The mobile vehicle body is equipped with a bracket that can support flux containers of slightly smaller volume, as well as air-pressing components, which facilitates the operation of air-pressing components. Moreover, the mobile vehicle body can provide unified support for multiple flux containers, which also facilitates the storage and unified movement of flux containers. Attached Figure Description

[0027] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, unless otherwise expressly indicated by the invention, the singular form is also intended to include the plural form. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof. As described in the background section, existing technologies suffer from low flux filling efficiency and easy waste when adding flux to the flux container. To address these technical problems, this invention proposes a flux filling device.

[0029] Example 1 In a typical embodiment of the present invention, reference is made to Figure 1As shown, a flux dispensing device includes a sleeve component 1, which can be sealed to the top opening of a flux container. A first tube 2 and a second tube 3 pass through the sleeve component 1 and enter the flux container 5. The first tube 2 is longer than the second tube 3. One end of the first tube 2 extends to the bottom of the flux in the flux container 5, and the other end of the first tube 2 can enter the equipment flux container 6. One end of the second tube 3 is positioned above the flux in the flux container 5, and the other end of the second tube 3 is connected to an air injection component 4. The air injection component 4 injects gas into the flux container 5 through the second tube 3. The gas pushes the flux in the flux container 5 through the first tube 2 into the equipment flux container 6.

[0030] It should be noted that, considering that there is a threaded protrusion at the top opening of the flux container after the sealing cap is removed, the protrusion forms an opening, and the sleeve part 1 is set to protrude downward and outward toward the lower edge of the flux container 5. The sleeve part 1 can wrap around the outside of the protrusion of the flux container from the outside of the flux container 5, so as to seal the connection with the flux container 5. It can also ensure that the sleeve part 1 has a certain degree of elasticity, so as to facilitate the sleeve part 1 to be fitted onto the cylinder wall of the flux container opening, and also to ensure the sealing and stability during the operation.

[0031] Specifically, the socket component 1 is a socket cover with a set depth. The depth of the socket cover is adapted to the depth of the cylinder wall at the opening of the flux container. The socket cover is made of elastic material, specifically rubber material, so that the socket component 1 can be fitted onto the opening of the flux container and play a sealing role, and is also easy to remove. It is easy to understand that in some examples, the socket component 1, the first tube 2, and the second tube 3 are integrated structural components, which facilitates the movement of the entire device and allows for quick connection or disconnection of the whole device from the top opening of the flux container 5, while ensuring airtightness when the device is connected to the top opening of the flux container 5. In other examples, the first tube 2 and the second tube 3 are movable relative to the socket component 1, so that the position of the first tube or the second tube at the socket component can be moved relative to the socket component 1. The first tube 2 and the second tube 3 are both rubber tubes, which can also ensure a certain degree of sealing.

[0032] refer to Figure 2 As shown, the lower edge of the sleeve component 1 facing the flux container 5 is a corrugated structure 7. The corrugated structure 7 has a tightening section. This not only facilitates the detachable connection between the sleeve component 1 and the flux container 5, but also ensures the sealing of the sleeve component when it is fitted onto the top opening of the flux container, preventing air leakage from the joint when inflating. It also facilitates the rapid increase of air pressure inside the flux container 5 when inflating.

[0033] It should be noted that, for reference Figure 3As shown, the first tube 2 is provided with a circumferential protrusion 8 on one side outside the flux container 5 to engage with the opening of the equipment flux container. The protrusion 8 is an annular protrusion. The outer diameter of the first tube 2 is smaller than the inner diameter of the opening of the equipment flux container. The outer diameter of the annular protrusion is adapted to the inner diameter of the opening of the equipment flux container. The first tube 2 is engaged with the opening of the equipment flux container through the protrusion 8, which ensures the reliability of the connection between the first tube and the equipment flux container 6 and prevents the first tube 2 from falling off the equipment flux container 6.

[0034] In another embodiment, a fixing rod is provided on one side of the opening of the flux container, with the fixing rod spaced apart from the opening of the flux container. A snap-fit ​​plate 9 is circumferentially provided on the side of the first tube 2 located outside the flux tank 5. The snap-fit ​​plate 9 is fixed to the circumference of the first tube 2, with a spaced distance between the snap-fit ​​plate 9 and the end of the first tube 2. The snap-fit ​​plate 9 can be detachably connected to the fixing rod on the side of the opening of the flux container. (See reference) Figure 4 As shown, a slot 10 is provided on one side of the snap-fit ​​plate 9 so that the snap-fit ​​plate 9 can be connected to the fixing rod. After the two are connected, during the process of injecting flux into the first tube 2, the stability of the first tube 2 can be guaranteed without external manual pressing. In this way, the flux can be effectively prevented from falling out of the opening of the equipment flux container during the process of flux flowing to the equipment flux container.

[0035] It is easy to understand that the air pumping component 4 is either a manual air pumping component or an automatic air pump, and the automatic air pump is an existing automatic air pump.

[0036] In this embodiment, flow meters are respectively installed in the first pipe 2 and the second pipe 3. The flow meters are connected to the controller, and the controller is connected to the air pump component, such as an automatic air pump. The controller is a PLC controller or other type of controller. The controller controls the closing of the air pump component based on the data transmitted by the flow meters, so that the flow rate in the first pipe and the flow rate in the second pipe are within a suitable range.

[0037] Additionally, it should be noted that the device also includes a mobile vehicle 11, see reference. Figure 5 As shown, the mobile vehicle body 11 may include a flat plate, and a plurality of wheels 12 are provided at the bottom of the flat plate. The wheels 12 are lockable wheels. The mobile vehicle body 11 supports the flux barrel 5. A limiting part 13 is provided on the surface of the mobile vehicle body 11. The limiting part 13 may be a limiting block to prevent the flux barrel 5 from falling off the mobile vehicle body 11. The limiting part 13 limits the flux barrel 5. The movement of the mobile vehicle body 11 can drive the flux barrel 5 to move. Considering that some flux cans are small in size, the mobile vehicle body 11 is equipped with multi-layer supports 14. The supports are rigid supports, and the supports 14 can be L-shaped plates. One end of the supports 14 is fixed to the flat plate or the next layer of supports. By supporting the flux cans 5 or the air inflator 4 through the supports 14 or the mobile vehicle body, the multiple layers of flux cans 5 can be supported separately, and multiple flux cans 5 can be supported uniformly. Of course, the flux cans 5 can also be directly stacked on the mobile vehicle body 11, but considering the stability of the flux can support, it is more common to choose to support the flux cans 5 by setting up supports. The distance between the horizontal section of the support and the mobile vehicle body or the horizontal section of two adjacent supports is adapted to the height of the flux cans. Multiple flux cans 5 can be supported simultaneously through the lower flux cans 5 and the supports 14.

[0038] The sleeve component 1 provided in this embodiment can be sealed to the top opening of the flux tank 5. The sleeve component 1 is provided with a first pipe 2 and a second pipe 3. The second pipe 3 is connected to the air injection component 4. The first pipe 2 connects the flux tank 5 and the equipment flux container 6. The air injection component 4 introduces gas into the flux tank 5, increasing the gas pressure in the flux tank 5. As a result, liquid is injected into the equipment flux container 6 through the second pipe 3. There is no need to use a funnel to assist in adding flux, nor is it necessary for multiple people to lift the flux tank 5, saving time and effort.

[0039] Example 2 This embodiment provides a method for adding flux to a device, including the flux adding device described in Embodiment 1, and includes the following: Move the flux container 5 to one side of the equipment flux container 6 and open the top opening of the flux container; Open the equipment flux container 6; Fit the fitting 1 onto the top opening of the flux tank, so that the first tube 2 and the second tube 3 enter the flux tank 5. One end of the first tube 2 extends to the bottom of the flux in the flux tank 5, and the other end of the first tube enters the equipment flux container. One end of the second tube 3 is placed above the flux in the flux tank 5, and the other end of the second tube 3 is connected to the air-pressing component 4. The air-injection component 4 injects gas into the flux tank 5 through the second pipe 3. The gas pushes the flux in the flux tank 5 through the first pipe 2 into the equipment flux container 6.

Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
