Description

Technical Field

[0001] This utility model relates to the field of reflow soldering equipment technology, and in particular to reflow soldering equipment with a separate anti-detachment component. Background Technology

[0002] Reflow soldering equipment, a key welding process in electronics manufacturing, works by heating the circuit board at high temperatures to melt and solidify solder paste, thereby achieving a reliable connection between electronic components and the circuit board. This high-temperature operation generates a large amount of hot air and welding fumes. To ensure a safe operating environment and stable welding process, the equipment typically requires a sophisticated ventilation system to effectively and promptly remove these hot air and fumes.

[0003] The exhaust system typically connects to the equipment body via branch pipes, which then connect to external exhaust ducts. Traditionally, these branch pipes are connected using clamps or other simple fastening methods. However, during prolonged operation, the ambient temperature of reflow soldering equipment rises significantly, causing thermal expansion and contraction of the connecting components. Simultaneously, mechanical vibrations from the equipment are inevitably transmitted to the exhaust duct connections.

[0004] Under the combined effects of high temperatures and continuous vibration, traditional clamp connections or simple fastening structures often struggle to maintain long-term stability and sealing. Connecting components may gradually loosen, potentially leading to the exhaust pipe detaching during operation, causing the leakage of high-temperature gases and harmful fumes, seriously threatening operator safety and the cleanliness of the production environment. Furthermore, loose connections can affect ventilation efficiency, negatively impacting the stability of the welding process and reducing product yield. Current technology lacks a reliable connection mechanism that can actively and continuously prevent the exhaust pipe from loosening or detaching under harsh operating conditions.

[0005] Therefore, this utility model proposes a reflow soldering equipment with a separate anti-detachment component to overcome the shortcomings of the prior art. Utility Model Content

[0008] The fixing assembly further includes a sleeve slidably connected between the first fixing block and the second fixing block; the fixing assembly also includes a fixing plate fixedly connected to the outer wall of the second fixing block, and a fixing groove is formed inside the fixing plate; the fixing assembly also includes a threaded rod rotatably housed inside the sleeve; the fixing assembly also includes a slider housed inside the sleeve and slidably connected to the sleeve, and the slider is threadedly connected to the threaded rod, and an oblique groove is formed on the upper surface of the slider; the fixing assembly also includes an L-shaped fixing post slidably fitted into the oblique groove, one end of the L-shaped fixing post being able to extend out of the sleeve and engage in the fixing groove. Through the ingenious combination of the above components, this utility model achieves stable and reliable pipe connection and double anti-detachment locking.

The elasticity of the spring can compensate for thermal expansion and contraction and vibration at the connection in a dynamic environment, maintaining continuous sealing.

[0012] Optionally, the upper surface of the slider has two oblique grooves, which are symmetrically distributed to guide the movement of the L-shaped fixed column more evenly.

[0030] Reference Figure 1 and Figure 2 One embodiment of this utility model is provided: Please refer to Figures 1 to 4 The utility model provides a reflow soldering equipment with a branch pipe anti-detachment component, which aims to solve the problem of insufficient reliability of the branch pipe connection of the exhaust system of the existing reflow soldering equipment, which is prone to loosening and detachment under high temperature and vibration environment.

[0031] like Figure 1 and Figure 2 As shown, the reflow soldering equipment with a branch-pipe anti-detachment assembly includes a reflow soldering body 2 and a reflow soldering cover 5 covering the reflow soldering body 2. The reflow soldering body 2 is used to support the heating and cooling zones for electronic component soldering operations, while the reflow soldering cover 5 is used for sealing and heat preservation. The reflow soldering body 2 is mounted on a bracket 1, which forms an integral mounting and support base for stably supporting the reflow soldering body 2. A control panel 3 is fixedly connected to the upper surface of the reflow soldering body 2. The control panel 3 is used to display the temperature distribution of each heating zone, the conveyor belt speed, and system operating status parameters in real time. Indicator lights 4 are also provided on the reflow soldering body 2 to visually display the equipment's operating status. A connecting pipe 6 is fixedly connected to the top of the reflow soldering cover 5, which is used to connect to an external exhaust system. The branch-pipe body 7 is reliably connected to the connecting pipe 6 through a sealing assembly 8, which ensures the sealing and stability of the exhaust path.

[0032] To prevent the main body 7 from loosening or falling off under the impact of high-temperature airflow or equipment vibration, a fixing component 9 is provided on the outside of the connection between the connecting pipe 6 and the main body 7. The fixing component 9 achieves mechanical locking and includes a clamp 901, a rubber ring 902, a first fixing block 903, a second fixing block 904, a threaded rod 905, a sleeve 906, a fixing plate 907, a slider 908, an inclined groove 909, an L-shaped fixing post 910, and a fixing groove 911.

[0033] A clamp 901 surrounds the outer wall of the connection between the connecting pipe 6 and the branch pipe body 7. A rubber ring 902 is provided on the inner wall of the clamp 901 to enhance the sealing and friction stability. A first fixing block 903 and a second fixing block 904 are fixedly connected to the outer wall of the clamp 901, forming an adjustable clamping structure. A sleeve 906 is fixedly connected between the first fixing block 903 and the second fixing block 904. A fixing plate 907 is fixedly connected to the outer wall of the second fixing block 904, and a fixing groove 911 is provided inside the fixing plate 907.

[0034] A threaded rod 905 is housed and rotatably connected inside the sleeve 906. One end of the threaded rod 905 extends out of the sleeve 906 and has an operable knob or interface. A slider 908 is housed inside the sleeve 906 and slidably connected to the sleeve 906. The slider 908 is threadedly connected to the threaded rod 905. When the threaded rod 905 rotates, the slider 908 slides along the axial direction of the sleeve 906. The upper surface of the slider 908 has at least one oblique groove 909, usually two oblique grooves 909. The oblique grooves 909 are used to guide the radial movement of the L-shaped fixing post 910. The L-shaped fixing post 910 is slidably fitted in the oblique groove 909. One end of the L-shaped fixing post 910 can extend out of the sleeve 906 and engage in the fixing groove 911 inside the fixing plate 907 to achieve mechanical limit locking.

[0035] The sealing assembly 8 includes a first connecting block 801 fixedly connected to the outer wall of the connecting pipe 6 and a second connecting block 802 fixedly connected to the outer wall of the branch pipe body 7. The inner wall of the first connecting block 801 has a sealing groove 806, which is an annular groove for accommodating a spring 805 and a sealing ring 804. The spring 805 is disposed in the sealing groove 806, with one end connected to the inner wall of the first connecting block 801 and the other end connected to the sealing ring 804. The sealing ring 804 is made of a high-temperature resistant and corrosion-resistant elastic material. A washer 803 is fixedly connected to the lower surface of the second connecting block 802. The washer 803 is also an annular structure and is used to fit with the sealing ring 804 to form a sealing interface.

[0036] In the assembled state, when the first connecting block 801 and the second connecting block 802 are mated, the washer 803 presses against the sealing ring 804. At this time, the clamping action of the clamp 901 compresses the spring 805, thereby pushing the sealing ring 804 and the washer 803 to fit tightly together, achieving an airtight seal and preventing high-temperature hot gas from leaking from the connection. This dynamic sealing structure composed of the spring 805, the sealing ring 804 and the washer 803 ensures that the connecting pipe 6 and the branch pipe body 7 can still maintain a tight fit when subjected to vibration or thermal expansion, and can also automatically compensate for the gap caused by thermal deformation, thereby improving the overall sealing performance and long-term stability.

[0037] In a preferred embodiment, in order to enhance the friction between the clamp 901 and the connection and to assist in sealing, a rubber ring 902 is provided on the inner wall of the clamp 901, and the rubber ring 902 is tightly fitted to the inner surface of the clamp 901.

[0038] In another preferred embodiment, to make the elastic compensation structure in the sealing assembly 8 more complete, a sealing groove 806 is formed on the inner wall of the first connecting block 801. A spring 805 and a sealing ring 804 are disposed inside the sealing groove 806. One end of the spring 805 is fixedly connected to the inner wall of the sealing groove 806, and the other end is connected to the sealing ring 804. A washer 803 is fixedly connected to the lower surface of the second connecting block 802. The washer 803 fits against the sealing ring 804 to form a dynamic sealing interface.

[0039] In another preferred embodiment, in order to provide stable guidance during the locking process of the L-shaped fixed post 910, two oblique grooves 909 are provided on the upper surface of the slider 908, and the two oblique grooves 909 are symmetrically distributed.

[0040] In another preferred embodiment, in order to provide a foundation for the overall installation and support of the equipment, the reflow soldering body 2 is mounted on a bracket 1, which is located below the reflow soldering body 2.

[0041] As another preferred embodiment, in order to facilitate the operator to monitor and adjust the equipment, a control panel 3 is fixedly connected to the upper surface of the reflow soldering body 2.

[0042] As another preferred embodiment, an indicator light 4 is provided on the body of the reflow soldering body 2 to intuitively display the operating status of the equipment.

[0043] Working principle: When using reflow soldering equipment with anti-detachment components for branch pipes to solder electronic components, the exhaust duct is installed first. The operator aligns the branch pipe body 7 with the connecting pipe 6, so that the first connecting block 801 on the outer wall of the branch pipe body 7 aligns with the second connecting block 802 on the outer wall of the connecting pipe 6. Subsequently, the clamp 901 is wrapped around the outside of the first connecting block 801 and the second connecting block 802. Then, by rotating the clamping part of the sleeve 906 or the threaded rod 905 on the fixing assembly 9, the first fixing block 903 and the second fixing block 904 are brought closer to each other, thereby tightening the clamp 901 and firmly securing it at the connection. The radial clamping force of the clamp 901 acts on the sealing assembly 8, causing the spring 805 in the sealing assembly 8 to be compressed, thereby pushing the sealing ring 804 and the gasket 803 to fit tightly together, achieving a reliable airtight seal between the connecting pipe 6 and the branch pipe body 7, preventing high-temperature hot gas from leaking from the connection. After the basic clamping is completed, in order to prevent the clamp 901 from loosening or falling off during equipment operation due to high temperature, strong vibration or thermal expansion and contraction, an anti-fall-off locking operation is required. The operator continues to rotate the threaded rod 905 located inside the sleeve 906. The rotational movement of the threaded rod 905 drives the slider 908 to slide axially inside the sleeve 906 through the threaded transmission. As the slider 908 moves forward axially, the inclined groove 909 on its upper surface provides guidance, forcing the L-shaped fixing post 910, which is slidably fitted in the inclined groove 909, to slide out radially. Finally, the L-shaped fixing post 910 will accurately engage with the fixing groove 911 inside the fixing plate 907, achieving a robust mechanical limit lock. The interlocking of the L-shaped fixing post 910 and the fixing groove 911 forms a double anti-detachment structure. Even if the equipment operates under extreme conditions such as high temperature, strong vibration, or thermal expansion and contraction, the clamp 901 can still maintain a stable locking state, ensuring that the branch pipe body 7 will not loosen or fall off, thereby ensuring the sealing and safety reliability of the exhaust system. At the same time, the spring 805 in the sealing assembly 8 provides elastic preload, which can automatically compensate for the small gaps caused by vibration or thermal deformation during equipment operation, and continuously maintain a tight seal at the connection.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
