Description

Technical Field

[0001] The utility model belongs to the technical field of welding equipment, and particularly relates to a flux recovery device for a string welding machine. Background Art

[0002] With the rapid development of the electronics manufacturing industry, string soldering machines play a vital role in the production of electronic components. In traditional string soldering processes, flux is widely used to improve soldering quality and efficiency. However, the extensive use of flux during soldering produces harmful fumes, polluting the environment and increasing operating costs. Existing recycling methods suffer from low efficiency and complex operations, making them inadequate for production needs.

[0003] In order to improve recycling efficiency, a corresponding flux recovery device is generally provided. For example, the flux recovery box structure for a reflow soldering machine with application number: CN201921216941.3 is easy to maintain. The device is rationally designed and easy to operate. The filter facilitates the filtering of the flux. The scraper can be pulled down to scrape off the flux stuck on the filter. After scraping off, the scraper is retracted by the coil spring inside the roller shutter and revolved back to the rotating column for easy collection. After the filter is used multiple times, the nut is rotated on the threaded rod to pull out the threaded rod and replace the filter, thereby improving the filtration efficiency. After collection, the collection bin can be pulled out of the device body through the slider for recycling and replacement. The setting of the insulation layer prevents the influence of external heat on the internal part. The setting of the temperature sensor and controller can drive the suction fan to start working after the cooling port reaches a certain temperature through telecommunication transmission, which facilitates the continuity of work. Each processing room is independent, which is also convenient for subsequent maintenance and repair.

[0004] However, in actual application, this recycling system still has several shortcomings. Specifically:

[0005] 1. The system lacks a filtering function for the extracted gas, causing particulate impurities in the gas to mix with the flux during the subsequent recovery process, which in turn has a negative impact on the subsequent use of the flux;

[0006] Second, the height of the air inlet cannot be adjusted, and the height of the air inlet cannot be flexibly adjusted according to actual application requirements, making it difficult to ensure that the gas is completely inhaled.

[0036] Please see the attached Figure 1-4 As shown, the present invention provides a flux recovery device for a string welding machine, comprising a refrigeration box 1 and an exhaust head 2, an air supply pipe 3 is connected between the refrigeration box 1 and the exhaust head 2, and a collecting cylinder 5 is threadedly connected to the lower end of the refrigeration box 1;

[0037] The filter mechanism 4 is provided in the exhaust head 2 and is used to remove particulate matter impurities in the inhaled gas;

[0038] Purification component 6, purification component 6 is arranged on the refrigeration box 1;

[0039] Partition 7 is fixedly connected to the refrigeration box 1 and is used to separate the internal space of the refrigeration box 1. A cooling pipe 9 is provided in the refrigeration box 1, and the upper end of the cooling pipe 9 is connected to the air supply pipe 3. The lower end of the cooling pipe 9 is fixedly connected to the drain pipe 10, and the drain pipe 10 extends to the bottom of the partition 7;

[0040] The adjusting mechanism 8 is provided between the refrigeration box 1 and the exhaust head 2 and is used to adjust the height of the exhaust head 2 .

[0041] The function of the refrigeration box 1 is to cool the medium inside. The refrigeration box 1 uses a product currently available on the market. When selecting a model, the specifications and usage scenario should be suitable, and the specific model specifications should be selected to meet the requirements of this application. The specific model specifications are not limited here. The cooling medium in the refrigeration box 1 can be water or other coolant.

[0042] The air duct 3 is made of flexible material, which is convenient for installation and adjustment of the direction of the air duct 3. The inner wall of the air duct 3 is smooth to reduce the resistance and noise during gas flow. The collecting tube 5 is used to collect the liquid flux condensed from the refrigeration box 1. The upper end of the collecting tube 5 is threadedly connected to the lower end of the refrigeration box 1, which ensures sealing while also facilitating disassembly. The filtering mechanism 4 ensures that the inhaled gas meets a high purification standard. The purification component 6 is used to further purify organic volatiles and bacteria in the air. The purification component 6 can be replaced or regenerated regularly to maintain its purification effect. The partition 7 divides the internal space of the refrigeration box 1 into two parts, upper and lower; the design of the adjustment mechanism 8 is simple and reliable, which facilitates the operator to quickly adjust the height of the exhaust head 2 according to the different heights and positions of the stringer. Through the reasonable design of the above structure, this practical stringer flux recoverer can effectively recover and purify flux, reduce environmental pollution, and improve production efficiency.

[0043] In a preferred embodiment, see Figure 2 The filtering mechanism 4 includes a negative pressure fan 401, which is installed in the exhaust head 2. A filter plate 402 is slidably inserted in the exhaust head 2. The exhaust head 2 is also rotatably connected to a rotating rod 403 by a bracket. A wind wheel 404 is installed at one end of the rotating rod 403, and a scraper 405 is connected to the other end of the rotating rod 403. The inner wall of the exhaust head 2 is fixedly connected to a guide seat 406, and a collection box 407 is provided at the lower end of the exhaust head 2.

[0044] In this embodiment, negative pressure blower 401 is activated, drawing gas into exhaust head 2. The gas then flows through filter plate 402 for filtration before entering air duct 3. During this process, filter plate 402 effectively blocks particulate matter and impurities in the gas, preventing them from mixing with the flux during subsequent recycling, thereby improving the quality of the flux. After being drawn in, the gas is blown along guide seat 406 toward impeller 404, driving impeller 404 to rotate. The rotation of impeller 404 further drives the rotation of rotating rod 403, which in turn drives scraper 405 to rotate, scraping away impurities intercepted by filter plate 402, preventing clogging of filter plate 402 and ensuring effective ventilation.

[0045] The air then flows along the air duct 3 into the cooling pipe 9, where it cools down through heat exchange, causing the flux to condense into a liquid state. The liquid flux then drips into the collection tube 5, while the remaining gas is discharged through the purification component 6.

[0046] In addition, it should be pointed out that a magnet block is installed on the sealing cover of the filter plate 402, and an iron block is set at the corresponding position of the sealing cover on the exhaust head 2. The two can be automatically adsorbed to ensure that the filter plate 402 is firmly installed to prevent it from loosening or falling off.

[0047] Next, please refer to Figure 3The purification component 6 includes an air outlet pipe, which is threadedly connected to the bottom of the side of the refrigeration box 1, and an activated carbon adsorption plate and a HEPA high-efficiency filter are arranged in the air outlet pipe.

[0048] In this embodiment, activated carbon adsorption plates are used to adsorb and remove volatile organic compounds (VOCs) from the exhaust gas. Furthermore, the system is equipped with a HEPA filter to further purify the exhaust gas to ensure compliance with national emission standards. The use of purification component 6 effectively reduces adverse environmental impacts.

[0049] Secondly, please refer to Figure 4 The adjustment mechanism 8 includes a sleeve plate 801, which is fixedly connected to the refrigeration box 1. The upper end of the sleeve plate 801 is plugged with an extension plate 802, and the upper end of the extension plate 802 is fixedly connected to the exhaust head 2. Lock holes 803 are distributed in an array on the extension plate 802. A support plate 804 is fixedly connected to the sleeve plate 801. A locking rod 805 is slidably plugged into the upper end of the support plate 804. A limiting ring 806 is fixedly sleeved on the outer wall of the locking rod 805, and a compression spring 807 is sleeved on one end of the locking rod 805.

[0050] In this embodiment, to adjust the height of the exhaust head 2, the user first pulls the locking rod 805 outward, compressing the compression spring 807 simultaneously to remove the locking rod 805 from the sleeve 801 and disengage the locking hole 803. At this point, the extension plate 802 is no longer restricted, and the user can adjust the height of the exhaust head 2 by pushing the extension plate 802 on the sleeve 801 to ensure more efficient air intake. After adjustment, the locking rod 805 is released, and the compression spring 807, under the action of the reset force, pushes the locking rod 805 back to its original position, inserting it into the corresponding locking hole 803, thereby securing the extension plate 802.

[0051] In a preferred embodiment, see Figure 3 The cooling pipe 9 is composed of a plurality of annularly distributed pipes, which is intended to increase the contact area between the pipe and the cooling water, thereby ensuring the cooling effect.

[0052] Next, please refer to Figure 1 The air duct 3 adopts a telescopic hose design, and a steel ring structure is added to the telescopic hose to ensure that it will not collapse when subjected to bending stress.

[0053] The working principle of this utility is:

[0054] During operation, exhaust head 2 draws in air containing flux vapor via negative pressure blower 401. The air first passes through filter plate 402 to remove large impurities. The air then flows along guide seat 406, driving impeller 404 to rotate. Impeller 404 then rotates rotating rod 403 and scraper 405, which removes impurities from filter plate 402 to prevent clogging. The purified air then flows through air duct 3 into cooling duct 9 within refrigeration box 1. There, the air is cooled, and the flux vapor condenses into liquid, dripping into collection tube 5. Purification assembly 6 further purifies the remaining air before it is discharged through the outlet pipe.

[0055] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this application shall be implemented in accordance with conventional means in the art unless otherwise specified or limited.
