Description

Technical Field

[0001] This utility model belongs to the field of welding cabinet technology, specifically, it relates to a water-cooled laser integrated welding cabinet. Background Technology

[0002] The water-cooled laser welding cabinet is an industrial device that integrates a laser welding host with a water-cooling system. It uses circulating coolant to efficiently dissipate heat and ensures stable operation of the laser.

[0003] The prior art discloses a laser welding machine cabinet with a water-cooling channel (CN116174952A), which includes a lower cabinet. A storage cabinet is fixedly connected to the top surface of the lower cabinet. An internal groove is opened on the inner side of the lower cabinet. The top surface of the storage cabinet is open. Cabinet doors are rotatably connected to the front end of the lower cabinet and the top surface of the storage cabinet. A through hole is opened through the storage cabinet and the internal groove. A partition is fixedly connected to the inner side of the internal groove near the top. A water-cooling pipe is located above the partition. The water chiller is placed below the partition and connected to the water-cooling pipe. The welding gun and connecting pipe are placed in the storage cabinet and coiled up. The connecting pipe of the welding gun passes through the through hole and connects to the laser. When the welding gun is used, the water chiller injects water into the water-cooling pipe. The water-cooling pipe is attached to the outer surface of the laser, which can effectively cool the laser during operation. Compared with traditional wind-powered cooling, the heat dissipation effect is better.

[0004] Research revealed that existing technologies use fixed water cooling channels for heat dissipation. However, the contact area and pressure of fixed-specification water cooling channels cannot be dynamically adjusted according to the laser's operating conditions. Under high-power conditions, the contact thermal resistance increases, which can easily lead to local overheating. Furthermore, the high-frequency vibrations of the laser during operation can be transmitted to the water tank or cabinet frame through the rigid water cooling channels. Over time, this can easily lead to water channel deformation, sealing failure, or component loosening.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

The water tank is fixedly installed on the top surface of the cabinet. A cabinet door is hinged to the top of the water tank and the front side of the cabinet. A back panel is fixedly installed on the back side of the cabinet by bolts. The retractable heat dissipation assembly has a set of retractable heat dissipation assemblies on each of the two sides of the cabinet. The two retractable heat dissipation assemblies are connected by the same water-cooling plate. The retractable heat dissipation assembly includes a circulation sleeve, a retractable circulation pipe, a mounting plate, and a fixing plate. The fixing plate is fixedly installed inside the cabinet. The circulation sleeve is fixedly installed on the side of the fixing plate away from the cabinet. The retractable circulation pipe is fixedly installed on the side of the mounting plate. The retractable circulation pipe slides inside the circulation sleeve.

[0007] In a preferred embodiment of this utility model, the water-cooled plate has a water-cooling channel inside, and two water inlets are symmetrically opened on one side of the bottom of the water-cooled plate. The water-cooled plate is connected to two telescopic heat dissipation components through the water inlets on both sides.

[0008] In a preferred embodiment of this utility model, a water pump is fixedly installed in one corner of the interior of the water tank. The pump's pumping end is connected to one corner of the top of the water-cooling plate, and the pump's outlet end is connected to an outlet pipe.

[0009] In a preferred embodiment of this utility model, heat dissipation fins are fixedly provided on the back side of the water-cooled plate, and three sets of electric fans are arranged in an array between the back side of the water-cooled plate and the heat dissipation fins. Three ventilation plates are arranged in an array on the back plate, and the electric fans are arranged corresponding to the ventilation plates.

[0010] In a preferred embodiment of this utility model, water supply pipes are fixedly provided at both outlet ends of the circulation sleeve, one of which is connected to the inlet, and the other is connected to the inside of the water tank.

[0014] 2.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0019] A water-cooled laser integrated welding cabinet, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, including The cabinet 10 and the water tank 11 are fixedly installed on the top surface of the cabinet 10. A cabinet door 15 is hinged above the water tank 11 and on the front side of the cabinet 10. The cabinet door 15 is made of double-layer hollow tempered glass, which has both observation and heat insulation functions. A back panel 12 is fixedly installed on the back side of the cabinet 10 by bolts. The retractable heat dissipation assembly has a set of retractable heat dissipation assemblies on each of the two sides inside the cabinet 10. The two retractable heat dissipation assemblies are connected by the same water-cooled plate 16. The retractable heat dissipation assembly includes a circulation sleeve 17, a retractable circulation pipe 19, a mounting plate 24, and a fixing plate 28. The fixing plate 28 of each assembly is fixed to the inner side wall of the cabinet 10 by four sets of expansion bolts. The circulation sleeve 17 is fixed to the side of the fixing plate 28 away from the cabinet 10 by argon arc welding. The retractable circulation pipe 19 is fixed to the side of the mounting plate 24. The retractable circulation pipe 19 slides inside the circulation sleeve 17. Both the circulation sleeve 17 and the retractable circulation pipe 19 are serpentine circulation structures. The gap between the circulation sleeve 17 and the retractable circulation pipe 19 is sealed by a sealant.

[0020] like Figure 4 and Figure 5 As shown, the water-cooled plate 16 has water-cooling channels 27 milled inside. The water-cooling channels 27 are distributed in a serpentine shape to ensure that the coolant flows fully inside the water-cooled plate 16. Two water inlets 26 are symmetrically opened on one side of the bottom of the water-cooled plate 16. The water-cooled plate 16 is connected to two telescopic heat dissipation components through the water inlets 26 on both sides. Each water inlet 26 is connected to a set of water supply pipes 25 by threads. The other end of the water supply pipes 25 is sealed to the flange of one end of the circulation sleeve 17 with a nitrile rubber sealing ring. like Figure 1 , Figure 2 and Figure 4 As shown, a water pump 20 is fixedly mounted on a bracket at one corner of the interior of the water tank 11. The pumping end of the water pump 20 is connected to the top corner of the water-cooled plate 16 via a flexible hose. The outlet end of the water pump 20 is connected to an outlet pipe 21, and the other end of the outlet pipe 21 is connected to the interior of the water tank 11, forming a complete water circulation path from the water tank 11 to the drain hole 14, to the water supply pipe 25, to the telescopic circulation pipe 19, to the circulation sleeve 17, to the water-cooled plate 16, to the flexible hose, to the water pump 20, and back to the water tank 11. Figure 1 and Figure 5 As shown, flanges are integrally formed on both outer sides of the circulation sleeve 17 for connecting water supply pipes 25. Water supply pipes 25 are fixedly installed at both outlet ends of the circulation sleeve 17. One water supply pipe 25 is connected to the inlet 26, and the other water supply pipe 25 passes through and connects to the inside of the water tank 11. like Figure 1 , Figure 2 and Figure 5 As shown, two drain holes 14 are symmetrically opened inside the water tank 11. The two drain holes 14 correspond to the water supply pipes 25 of the two telescopic heat dissipation components respectively. The flange at the other end of the circulation sleeve 17 is connected to another set of water supply pipes 25. The water supply pipes 25 pass through the top surface of the cabinet 10 and are sealed and connected to the drain holes 14 opened inside the water tank 11. The two drain holes 14 are symmetrically distributed inside the water tank 11 to ensure that the water flow of the telescopic heat dissipation components on both sides is balanced. like Figure 2and Figure 5 As shown, four sets of dampers 18 are provided between the mounting plate 24 and the fixed plate 28. The mounting plate 24 is elastically connected to the fixed plate 28 through the dampers 18. The dampers 18 are hydraulic dampers, and their two ends are respectively hinged to the mounting plate 24 and the fixed plate 28 through pins to ensure that the dampers 18 can extend and retract synchronously and provide buffer force when the telescopic circulation tube 19 slides. The telescopic circulation tube 19 is embedded and slides in the circulation sleeve 17. The telescopic circulation tube 19 is snapped in the circulation sleeve 17 and slides and retracts along the direction of the circulation sleeve 17 towards the laser.

[0021] The workflow is as follows: After the equipment is started, the water pump 20 begins to work. The coolant in the water tank 11 falls by gravity, enters the water supply pipes 25 on both sides through the drain hole 14, and then enters the circulation sleeves 17 and telescopic circulation pipes 19 on both sides. The coolant circulates through the circulation sleeves 17 and enters the inlet 26 through the water supply pipe 25 at the other end. Then, it flows into the water cooling channel 27 of the water cooling plate 16 through the inlet 26. The coolant is then pumped out by the water pump 20 through the hose and exits through the outlet pipe 21. The coolant is re-drained into the water tank 11. During this process, as the coolant flows through the circulation sleeves 17 and the telescopic circulation pipes 19 on both sides, it absorbs the heat generated by the laser in the laser welding equipment and is carried back into the water tank 11 to complete the circulation. In this process, the damper 18 provides elastic support, allowing the mounting plate 2 to adaptively adjust its position and contact pressure according to the shape and vibration of the laser. When the laser vibrates, the damper 18 absorbs the vibration energy and prevents the vibration from being transmitted to the cabinet 10 frame and the water tank 11 system through the rigid connection.

[0022] like Figure 1 and Figure 3 As shown, heat dissipation fins 23 are fixedly attached to the back side of the water-cooled plate 16 by applying thermally conductive silicone grease. Three sets of electric fans 22 are arranged in an array between the back side of the water-cooled plate 16 and the heat dissipation fins 23. The electric fans 22 are fixed to the back side of the water-cooled plate 16 by brackets, and their air outlets face the heat dissipation fins 23. Three ventilation plates 13 are arranged in an array on the back plate 12. Each ventilation plate 13 is fitted with a dustproof mesh to prevent welding dust from entering the cabinet. The electric fans 22 are arranged corresponding to the ventilation plates 13. The central axis of each electric fan 22 is aligned with the central axis of the ventilation plate 13 on the back plate 12 to ensure that the airflow blown by the fan can efficiently pass through the heat dissipation fins 23 and be discharged from the cabinet through the ventilation plate 13.

[0023] The working principle is as follows: After the coolant absorbs the heat generated by the laser through the telescopic heat dissipation components on both sides, the coolant carrying the heat enters the water cooling channel 27 of the water cooling plate 16. At this time, the water cooling plate 16 transfers part of the heat absorbed by the coolant to the heat dissipation fins 23 through thermal grease. The large surface area of ​​the heat dissipation fins 23 can quickly diffuse the heat to the fin surface. At this time, three electric fans 22 start simultaneously, and the generated airflow passes through the heat dissipation fins 23. The airflow and the fin surface undergo forced convection heat exchange, which carries away the heat from the fin surface. The hot air is discharged from the cabinet through the ventilation plate 13 of the back plate 12. At this time, part of the heat in the coolant is dissipated. At the same time, the coolant after dissipating part of the heat is pumped out of the water cooling channel 27 by the water pump 20, and then flows back to the water tank 11 through the water outlet pipe 21 to complete the circulation.
