Description

Technical Field

[0001] This utility model relates to the field of laser welding guns, and in particular to a laser welding gun structure with an embedded dustproof sealing ring. Background Technology

[0002] In modern manufacturing, laser welding guns, as core equipment for achieving efficient and precise welding, are widely used in various fields such as electronics, automobiles, and aerospace. Their operation relies on internal optical lenses to focus and transmit the laser beam. The cleanliness and stability of these optical lenses directly affect the laser energy transmission efficiency and welding quality; therefore, protecting the optical lenses is crucial.

[0003] Currently, most laser welding guns use a sealed outer shell to protect the optical lenses. A removable cover plate is installed on the top of the shell for routine maintenance and lens replacement. The cover plate is connected to the welding gun body by simple bolts or snap-fit ​​connections. A common gasket is placed between the cover plate and the lens, and a basic seal is achieved through mechanical pressure. This structure can, to a certain extent, prevent external impurities from entering and maintain the normal operation of the internal optical system.

[0004] However, due to the limited sealing performance of the connection structure between the cover plate and the laser welding gun body, dust in the air can easily enter the internal space through the tiny gaps between the two during equipment operation and adhere to the surface of the optical lens. As dust accumulates, it not only leads to increased laser energy loss and decreased welding precision, but in severe cases, it can also cause localized overheating of the lens, resulting in irreversible damage and greatly affecting the service life of the equipment and the welding effect. To address these issues, a laser welding gun structure with an embedded dustproof sealing ring is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a laser welding gun structure with an embedded dustproof sealing ring, which aims to improve the problem that dust in the air can easily adhere to the surface of the optical lens through the gap between the cover plate and the laser welding gun, affecting the use of the equipment.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-4 The present invention provides an embodiment of a laser welding gun structure with an embedded dustproof sealing ring, comprising a laser welding gun 1. When the laser welding gun 1 is used, a laser beam is first generated by a laser generator and transmitted to an optical lens 4 through an internal light guiding system. The optical lens 4 focuses the laser beam and concentrates the energy on the part to be welded. The high energy density laser beam instantly melts the metal material, causing it to fuse and form a welding point, thereby completing the welding task. This is prior art and will not be described in detail here. Multiple optical lenses 4 are slidably connected inside the laser welding gun 1. A cover plate 2 is provided on the top of the optical lens 4, and a sealing component is provided on one side of the cover plate 2.

[0035] The sealing assembly includes a sealing ring 3, the outer wall of which is fixedly connected to one side of the cover plate 2. The sealing ring 3 is used to tightly fit against the inner wall of the second slot 20 to prevent dust from entering the laser welding gun 1. Multiple slots 7 are provided inside the cover plate 2, which cooperate with the card plate 6 to fix the cover plate 2. A second slot 20 is provided inside the laser welding gun 1 to accommodate the sealing ring 3 and ensure a sealing effect. The sealing ring 3 fits against the inner wall of the second slot 20. Multiple fixing posts 11 are fixedly connected inside the laser welding gun 1. The fixing posts 11 support the connecting posts 10 and provide sliding guidance. A connecting post 10 is slidably connected to the inner wall of each fixing post 11. The connecting post 10 is used to drive the card plate 6 to move up and down. A limit ring 8 is rotatably connected inside each connecting post 10. The limit ring 8 is used to limit the rotation range of the connecting plate 9 to prevent excessive rotation. A connecting plate 9 is fixedly connected to the inner wall of each limit ring 8. The connecting plate 9 is used to connect the handle 1. 5 and limit ring 8 transmit rotational force. Each connecting plate 9 has a handle 1 5 fixedly connected to its top. The handle 1 5 is used by the operator to pull and rotate the plate 6. Each handle 1 5 has a plate 6 fixedly connected to its outer wall. The plate 6 is used to cooperate with the slot 1 7 to fix the position of the cover plate 2. Each plate 6 is in contact with the inner wall of the slot 1 7. Multiple plates 6 have a spring-loaded assembly on their outer walls. The spring-loaded assembly includes multiple springs 12. The springs 12 are used to provide a rebound force so that the plate 6 automatically engages with the slot 1 7. Each spring 12 is located at the bottom of the plate 6. Each spring 12 is located inside the fixing post 11. One end of each spring 12 is fixedly connected to the bottom of the inner wall of the fixing post 11. The top of each spring 12 is fixedly connected to the bottom of the connecting post 10. The cover plate 2 is rotatably connected to the outer wall of the laser welding gun 1. Each cover plate 2 has a handle 2 19 fixedly connected to its top. The handle 2 19 is used by the operator to rotate the cover plate 2. The outer wall of the laser welding gun 1 is equipped with a heat dissipation assembly.

[0036] Reference Figure 1 and Figure 5 The heat dissipation assembly includes multiple small fans 14, which generate airflow to accelerate heat dissipation. The multiple small fans 14 are located outside the laser welding gun 1. A fixing block 13 is fixedly connected to the outer wall of the laser welding gun 1 to fix the position of the small fans 14. The outer walls of the small fans 14 on both sides are fixedly connected to the inner wall of the fixing block 13. Metal heat sinks 16 are fixedly connected to both sides of the laser welding gun 1. The metal heat sinks 16 absorb and dissipate the heat of the laser welding gun 1. Multiple connecting plates 15 are fixedly connected to one side of each metal heat sink 16. The connecting plates 15 support the rotating wheels 17 and the ventilation holes 18. Multiple rotating wheels 17 are rotatably connected between two adjacent connecting plates 15. The rotating wheels 17 guide the airflow and enhance the heat dissipation effect. Multiple ventilation holes 18 are opened inside each connecting plate 15 to allow airflow and further reduce the surface temperature of the laser welding gun 1.

[0037] Working principle: During the sealing process of the top of the optical lens 4, the cover plate 2 is rotated so that one side of the cover plate 2 is in contact with the top of the laser welding gun 1. At this time, the sealing ring 3 will move to the inner wall of the sealing ring 3, and the sealing ring 3 will seal the connection between the cover plate 2 and the laser welding gun 1. Then, the handle 5 is pulled upward so that the connecting post 10 slides on the inner wall of the fixed post 11, and the spring 12 is stretched. When the retaining plate 6 on the outer wall of the handle 5 moves to the top of the cover plate 2, the retaining plate 6 on the outer wall of the handle 5 is rotated 90 degrees so that the limiting ring 8 on the outer wall of the connecting plate 9 is inside the connecting post 10. Rotate to prevent the rotational force of the clamping plate 6 from affecting the connecting column 10. Then release the pulling force on the handle 5 and use the rebound force of the spring 12 to push the clamping plate 6 into engagement with the inner wall of the slot 7, blocking the top of the cover plate 2 and fixing the position of the cover plate 2. This ensures that the sealing ring 3 is always fully in contact with the inner wall of the slot 20, achieving a sealing effect on the top of the optical lens 4. This solves the problem that dust in the air can easily adhere to the surface of the optical lens 4 through the gap between the cover plate 2 and the laser welding gun 1, affecting the use of the equipment, and enhances the dustproof effect of the surface of the optical lens 4.

[0038] During the heat dissipation process on the surface of the laser welding gun 1, a small fan 14 is activated to blow air onto the surfaces of the metal heat sink 16 and the rotating wheel 17. The airflow dissipates the heat radiating from the surface of the metal heat sink 16. As the rotating wheel 17 rotates, it guides more airflow onto the surface of the metal heat sink 16. The rotating wheel 17 also generates airflow as it rotates. This airflow flows through the ventilation holes 18 on the outer wall of the laser welding gun 1, ultimately achieving heat dissipation on the surface of the laser welding gun 1. This solves the problem that traditional equipment usually relies on natural wind for heat dissipation, which can easily lead to untimely heat dissipation and equipment damage when the equipment is running at high speed or in high-temperature environments. This improves the heat dissipation efficiency of the equipment.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
