Abstract
Description
Technical Field
[0001] The present application relates to the technical field of welding equipment, and in particular to a hand-immersion flat jet welding device. Background Art
[0002] A hand-immersion flat jet soldering system combines manual operation with jet soldering technology. It is primarily used to immerse a pre-populated PCB into a molten tin bath, where soldering is achieved through jet flow. The system heats the bath to melt the tin. The operator then holds the PCB in a handheld fixture and immerses it in the bath. During the immersion process, the molten tin, in the form of a jet, contacts the soldering surface of the PCB, forming a solder joint. After soldering is complete, the operator removes the PCB from the bath, cools it, and inspects it.
[0003] In the prior art, operators will become fatigued after working continuously for a period of time, resulting in uneven tin on the PCB board. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this application is to provide a hand-immersion flat jet soldering device to solve the technical problem that fatigue occurs during continuous manual operation in the existing technology, resulting in uneven soldering on the PCB board.
[0005] The above-mentioned purpose of the present application is achieved through the following technical solutions: a hand-immersion flat jet soldering device, comprising a storage container for holding tin water, a plurality of support frames for placing PCB boards are provided on the upper end of the storage container, and the support frames are L-shaped. A drive component that can be adjusted up and down is provided between the storage container and the support frames, and a stabilizing component for improving the stability of the PCB board is provided between the support frames.
[0006] By adopting the above technical solution, when the PCB board needs to be soldered, the PCB board is placed between the rectangular support frames, and then the support frames are driven downward by the driving component. When the bottom of the PCB board contacts the tin water, the PCB board is lifted by the driving component to complete the soldering. By adopting mechanical drive to drive manual drive, errors caused by manual operation are reduced.
[0007] Furthermore, the stabilization component includes a plug-in rod fixedly connected to each support frame, adjustment blocks are provided on both sides of the plug-in rod, the plug-in rod is plugged into the adjustment block, and clamping plates are fixedly provided at both ends of the rod surface of the plug-in rod, and an extrusion spring is sleeved on the plug-in rod, and the extrusion spring is provided between the clamping plate adjustment block.
[0008] By adopting the above technical solution, when the PCB board is placed on the support frame before soldering, the pressure of the extrusion spring will squeeze the support frame around the PCB board, thereby fixing it, ensuring that the PCB board is fixed during soldering.
[0009] Furthermore, an inclined surface is provided on one end of the upper end of the support frame facing the PCB board.
[0010] By adopting the above technical solution, when placing the PCB board, the support frame can be opened along the inclined surface by pressing the PCB board.
[0011] Furthermore, a slot is provided on the support frame on one side of the support frame where the inclined surface is provided.
[0012] By adopting the above technical solution, the pressed PCB board will enter the slot along the inclined surface, and the PCB board will be fixed due to the squeezing on all sides.
[0013] Furthermore, the driving assembly includes a movable bracket installed on the upper end of the storage container, a driving motor is fixedly provided on the upper end of the movable bracket, the output end of the driving motor faces upward and a driving gear is fixedly provided on the output end, a driving rod is provided around the driving motor, a driven gear is fixedly provided on one end of the driving rod close to the driving motor and is engaged with the driving gear, the driving rod is rotatably connected to the movable bracket, a traction rope is fixedly provided on the driving rod, and the other end of the traction rope is fixedly connected to the support frame.
[0014] By adopting the above technical solution, the drive motor is a motor that can be driven forward and reverse. The drive motor drives the drive rods around to rotate, driving the traction rope to be reeled or released, thereby pulling the support frame up and down.
[0015] Furthermore, the movable bracket is slidably connected to the storage container.
[0016] By adopting the above technical solution, after the PCB board is soldered, the movable bracket is lifted by the driving component, and then the movable bracket is slid so that the movable bracket is not at the upper end of the storage container, and then the staff can remove the PCB board to reduce the impact of high temperature on the staff.
[0017] Furthermore, an anti-scalding film is fixedly provided on the outer side of the movable bracket.
[0018] By adopting the above technical solution, the problem of burning hands due to high temperature can be avoided when the movable bracket is slid.
[0019] Furthermore, the anti-scalding film is made of polymer material.
[0020] In summary, the present application provides the following beneficial technical effects: By integrating mechanical drive, stabilizing components, and an adjustable support frame, precise control of the PCB soldering process is achieved. This not only significantly reduces manual operation errors, improves soldering accuracy and consistency, but also significantly enhances production efficiency. Furthermore, the use of mechanical drive eliminates the risk of direct contact between operators and hot molten solder, effectively ensuring operational safety. Furthermore, the device can flexibly adapt to PCBs of varying sizes and thicknesses, enhancing the versatility and applicability of the equipment and further optimizing the production process.

[0024] The present application is further described in detail below with reference to the accompanying drawings.
[0025] Example, see Figure 1 、 Figure 2 A hand-immersion flat jet soldering device includes a storage container 1 for holding molten tin. A plurality of support frames 26 for placing PCBs are provided on the upper end of the storage container 1. The support frames 26 are L-shaped. A drive component that can be adjusted up and down is provided between the storage container 1 and the support frames 26. A stabilizing component that improves the stability of the PCB is provided between the support frames 26. When soldering is required on the PCB, the PCB is placed between the support frames 26, and the support frames 26 are driven downward by the drive component. When the bottom of the PCB contacts the molten tin, the drive component lifts the PCB to complete the soldering. By adopting mechanical drive to drive manual drive, errors caused by manual operation are reduced.
[0026] In this embodiment, the stabilizing assembly includes a plug-in rod 27 fixedly connected to each support frame 26, and adjustment blocks 30 are provided on both sides of the plug-in rod 27. The plug-in rod 27 is plugged into the adjustment blocks 30, and clamping plates 29 are fixedly provided at both ends of the rod surface of the plug-in rod 27. An extrusion spring 28 is sleeved on the plug-in rod 27, and the extrusion spring 28 is provided between the clamping plates 29 and the adjustment blocks 30.
[0027] When the PCB is placed on the support frame 26 before soldering, the pressure of the squeezing spring 28 squeezes the support frame 26 around the PCB, thereby fixing it and ensuring that the PCB is fixed during soldering.
[0028] In this embodiment, an inclined surface is provided on the upper end of the support frame 26 toward one end of the PCB board. When the PCB board is placed, the support frame 26 can be opened along the inclined surface by pressing the PCB board.
[0029] In this embodiment, a slot is provided on the support frame 26 on one side of the inclined surface. The PCB board pressed down will enter the slot along the inclined surface, and the PCB board will be fixed due to the squeezing of the surroundings.
[0030] In this embodiment, the driving assembly includes a movable bracket 2 installed on the upper end of the storage container 1, and a driving motor 21 is fixedly provided on the upper end of the movable bracket 2. The output end of the driving motor 21 faces upward and a driving gear 22 is fixedly provided on the output end. A driving rod 23 is provided around the driving motor 21. A driven gear 24 is fixedly provided on one end of the driving rod 23 close to the driving motor 21 and engages with the driving gear 22. The driving rod 23 is rotatably connected to the movable bracket 2, and a traction rope 25 is fixedly provided on the driving rod 23. The other end of the traction rope 25 is fixedly connected to the support frame 26.
[0031] The driving motor 21 is a motor that can be driven forward and reversely. The driving motor 21 drives the driving rods 23 around to rotate, driving the traction rope 25 to be wound or released, thereby pulling the support frame 26 up and down.
[0032] In this embodiment, the movable bracket 2 is slidably connected to the storage container 1. After the PCB board is soldered, the movable bracket 2 is lifted by the driving component, and then the movable bracket 2 is slid so that the movable bracket 2 is not on the upper end of the storage container 1. Then the staff can remove the PCB board to reduce the impact of high temperature on the staff.
[0033] In this embodiment, an anti-scalding film is fixedly provided on the outer side of the movable bracket 2 .
[0034] When sliding the movable bracket 2, avoid the problem of burning your hands due to high temperature.
[0035] In this embodiment, the anti-scalding film is made of polymer material.
[0036] The specific implementation process: First, the PCB to be soldered is precisely placed between the support frames 26. These support frames 26 are designed in an L-shape, with a sloped surface on the upper end facing the PCB to facilitate easy placement and positioning of the PCB. Next, the stabilization assembly, comprising the plug-in rod 27, adjustment block 30, clamping plate 29, and compression spring 28, works together to securely fix the PCB, ensuring that the PCB will not move or tilt due to external forces during the soldering process, thus ensuring precise and consistent soldering.
[0037] Subsequently, the drive assembly is started. The assembly consists of key components such as the movable bracket 2, the drive motor 21, the drive gears 22, the drive rod 23, and the traction rope 25. The drive motor 21 can be driven forward and reverse, and through its drive, the drive rods 23 on all sides rotate accordingly. The driven gears 24 on the drive rod 23 are tightly engaged with the drive gears 22. When the drive rod 23 rotates, it drives the traction rope 25 to reel in or release, thereby achieving the function of pulling the support frame 26 and the PCB board up and down. At this time, the drive motor 21 is started, and the drive assembly drives the support frame 26 and the PCB board to move steadily downward until the bottom of the PCB board is fully in contact with the tin water, and the soldering operation is carried out.
[0038] During the soldering process, the stabilizing assembly continues to function, ensuring that the PCB remains fixed and prevents any possible movement or tilting, thereby ensuring the accuracy and quality of the soldering. After soldering is completed, the drive motor 21 is restarted, and the drive assembly lifts the support frame 26 and the PCB upward and away from the solder liquid.
[0039] At this point, the movable bracket 2 is slid to the side of the storage container 1, allowing the staff to remove the soldered PCB in a safe environment, avoiding possible injuries caused by high temperatures. It is worth noting that the anti-scalding film (made of polymer material) fixed on the outside of the movable bracket 2 can effectively prevent burns caused by high temperatures during the sliding process, further improving the safety of the operation.
[0040] Finally, the movable bracket 2 is reset to its initial position, preparing for the next PCB soldering operation. Simultaneously, the status of the stabilizing and driving components is thoroughly inspected and adjusted to ensure the device's continued stable operation, providing strong support for subsequent soldering operations. Through this series of precisely designed steps and processes, this hand-immersion flat jet soldering device achieves efficient, precise, and safe control of the PCB soldering process.
[0041] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
