Description

Technical Field

[0001] This invention relates to the field of fan processing technology, specifically to a high-efficiency welding device for fan production and processing. Background Technology

[0002] A fan is an electrical appliance that uses an electric motor to drive blades to rotate, accelerating airflow. Cooling fans are core heat dissipation components in electronic devices such as laptops, removing internal heat through forced airflow exchange. With the performance upgrades of laptops and other electronic devices, the power consumption and heat generation of core components such as CPUs and GPUs continue to increase, especially in niche categories like thin and light laptops and gaming laptops, where the compact internal space leads to heat accumulation. Highly efficient cooling fans are needed to ensure stable operation. The mainstream design uses axial fans, which consist of blades, a motor, bearings (ball bearings or oil bearings), and a shroud. The fan blades are the most important component; they are usually welded to a rotor, which is mounted on the motor shaft to form a linkage. Factors such as the tilt angle between the blades and the rotor, the relative position of the blades, and the bending angle of the blades themselves directly affect the airflow generated by the fan, thus affecting the airflow efficiency. With the continued growth in demand for fans for laptop cooling, the market is increasingly demanding higher requirements for fan production efficiency, welding precision, and working environment. Currently, the general method for welding blades to the wheel is to place the wheel on a clamping fixture. After the welder finishes welding the upper surface of one blade, he waits for the welding point on the upper surface of the blade to cool down before welding the lower surface of the blade, until all blades are welded.

[0003] However, the clamping mechanisms of existing traditional devices are mostly rigid designs. For fan workpieces with different curvatures and diameters, it is necessary to frequently change special fixtures, which not only increases the cost of equipment investment, but also causes the disassembly and debugging of fixtures to occupy a lot of production time, seriously reducing the efficiency of mass production. On the other hand, some manually adjustable clamping devices rely on the operator's experience to control the clamping force, which is prone to uneven force and workpiece displacement. At the same time, the existing fixed dust collection hoods are in a fixed position and can only cover a limited welding area. When the workpiece adjusts its angle or welding position as the welding process progresses, it is easy to form a blind spot for adsorption, and a large amount of metal fume cannot be effectively captured, resulting in excessive dust concentration in the workshop. Moreover, independent mobile dust collection equipment needs to be manually pushed to the welding area by the operator, which is completely disconnected from the material fixing process. This not only increases the intensity of manual labor, but also makes it easy for the dust to spread due to the delay in operation.

[0004] To address the aforementioned issues, innovative designs are urgently needed based on existing approaches. Summary of the Invention

[0005] The purpose of this invention is to provide a high-efficiency welding device for fan manufacturing and processing, so as to solve the problems mentioned in the background art. The technical solution of this invention addresses the problem that the existing technical solutions are too simplistic and provides a solution that is significantly different from the existing technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency welding device for fan production and processing, comprising a welding machine base, a sliding rail fixedly installed on the welding machine base, welding parts installed on the sliding rail, a platform fixedly installed on the welding machine base, a rotating motor fixedly installed inside the platform, a friction wheel fixedly installed on the rotating motor, a shelf rotatably installed on the platform, a support block installed on the shelf, a limit block fixedly installed on the inner wall of the support block, a dust collection box slidably installed on the platform, and a vent installed on the dust collection box; A fixed support mechanism is mounted on a support block and is used to provide stable support for the welding material. A swing adjustment mechanism is installed inside the dust collection box and is used to adjust the swing amplitude of the air vent.

[0007] Preferably, the fixed support mechanism includes a movable rod, which is slidably installed inside the support block. The upper surface of the movable rod has a spiral groove, and the lower surface of the movable rod has symmetrical sliding grooves. The spiral groove cooperates with a limiting block on the inner wall of the support block.

[0008] Preferably, an abutment plate is slidably installed inside the support block at equal angles, the top of the abutment plate is arc-shaped when viewed from above, a receiving plate is fixedly installed at the upper end of the movable rod, a connecting block is fixedly installed on the abutment plate, an electric push rod is fixedly installed on the support block, and the top end of the electric push rod is slidably installed at the lower end of the receiving plate.

[0009] Preferably, the fixed support mechanism further includes a rotating disk, which is rotatably installed inside the support block. The rotating disk has arc-shaped track grooves at equal angles, and a connecting block is slidably installed in the track groove. A protrusion is fixedly installed on the inner wall of the rotating disk, and the protrusion is movably installed in the sliding groove.

[0010] Preferably, a pressing block is slidably installed inside the shelf by a spring, and a movable rod is fixedly connected to the upper end of the pressing block. The pressing block is trapezoidal when viewed from the front. A movable plate is elastically slidably installed inside the shelf, and the inclined surface of the pressing block abuts against the movable plate.

[0011] Preferably, a connecting rod is fixedly installed at the right end of the movable plate, and the upper end of the connecting rod is fixedly installed on the lower slider of the dust collection box.

[0012] Preferably, the swing adjustment mechanism includes an oil cylinder, which is installed inside the platform, and the piston rod on the oil cylinder is fixedly connected to the lower slider of the dust collection box.

[0013] Preferably, the swing adjustment mechanism further includes a deflection block, which is installed inside the dust collection box, and the air vent is installed through the deflection block. A groove is provided at the lower end of the deflection block.

[0014] Preferably, a rotary motor is fixedly installed inside the dust collection box, a rotating wheel is fixedly installed at the output end of the rotary motor, and an oil cylinder two is fixedly installed inside the rotating wheel. The oil cylinder two and the oil cylinder one are interconnected through an infusion hose.

[0015] Preferably, an abutment rod is slidably mounted on the rotating wheel, the upper end of the abutment rod is slidably mounted in the bottom groove of the deflection block, and the abutment rod is connected to the piston rod of the second oil cylinder.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This device's fixed support mechanism breaks through the traditional single clamping mode, constructing a linkage system of "movable rod-rotating disk-abutment plate," achieving adaptive fixation through multiple structural combinations. The spiral groove on the movable rod forms a guiding engagement with the limiting block on the inner wall of the support block. When the movable rod is pressed down, the spiral groove is forcefully driven to rotate the movable rod synchronously. The sliding groove on the lower surface of the movable rod is linked with the protrusion on the inner wall of the rotating disk, driving the rotating disk to rotate synchronously. The arc-shaped track grooves opened at equal angles on the rotating disk slide in engagement with the connecting block of the abutment plate, ultimately driving multiple sets of abutment plates to synchronously contract or open at equal angles along the support block. At the same time, the top of the abutment plate adopts an arc-shaped design, which can fit tightly with the arc-shaped surface of the fan workpiece. It can adapt to different sizes of fan materials without changing special fixtures, avoiding material displacement caused by uneven force on a single abutment plate, significantly improving welding positioning accuracy, and reducing welding defects caused by material shaking. Secondly, the combination of the arc-shaped abutment plate and the adaptive adjustment structure greatly reduces the frequency of fixture replacement, shortens equipment debugging time, and improves the continuity and efficiency of fan production and processing, making it particularly suitable for batch production scenarios of multi-specification fans.

[0017] The adsorption angle is dynamically adjusted through hydraulic control. During the material fixing stage, the movable rod presses down, causing the extrusion block to move down synchronously. The trapezoidal extrusion block pushes the moving plate to slide laterally through the inclined surface. The moving plate, via the connecting rod, drives the dust collection box to adjust its distance from the welding area according to the weight of different materials, achieving automatic positioning of the adsorption position. The linkage design of fixing and dust collection allows the dust collection box to automatically adjust the distance between the dust collection mechanism and the welding point without manual operation. At the same time, the vent is adjusted by hydraulic and mechanical means to ensure that welding fumes are accurately captured, greatly improving the dust adsorption efficiency, improving the workshop working environment, and reducing the health risks to operators. In the swing adjustment mechanism, the deflection block is pushed to drive the vent to swing at multiple angles, improving the dynamic adaptability of the adsorption position and angle. This allows the vent to adjust in real time with the welding trajectory of the fan, avoiding the adsorption blind spots of traditional fixed dust collection ports, further improving the cleanliness of the welding environment, while reducing manual intervention and lowering the intensity of operation.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-7 The present invention provides a technical solution: a high-efficiency welding device for fan production and processing, including a welding machine base 1, a sliding rail 2 fixedly installed on the welding machine base 1, a welding part 3 installed on the sliding rail 2, a platform 4 fixedly installed on the welding machine base 1, a rotating motor 5 fixedly installed inside the platform 4, a friction wheel 6 fixedly installed on the rotating motor 5, a platform 7 rotatably installed on the platform 4, a support block 8 installed on the platform 7, a limit block 801 fixedly installed on the inner wall of the support block 8, a dust collection box 9 slidably installed on the platform 4, and a vent 10 installed on the dust collection box 9; A fixed support mechanism is installed on the support block 8 and is used to provide stable support for the welding materials. The swing adjustment mechanism is installed inside the dust collection box 9 and is used to adjust the swing amplitude of the air vent 10.

[0022] In one embodiment of the present invention, the fixed support mechanism includes a movable rod 11, which is slidably installed in the support block 8. The upper surface of the movable rod 11 is provided with a spiral groove 1101, and the lower surface of the movable rod 11 is provided with symmetrical sliding grooves 1102. The spiral groove 1101 is used in conjunction with the limiting block 801 on the inner wall of the support block 8.

[0023] In one embodiment of the present invention, an abutment plate 12 is slidably mounted inside the support block 8 at equal angles. The top of the abutment plate 12 is arc-shaped when viewed from above. A support plate 1103 is fixedly mounted on the upper end of the movable rod 11. A connecting block 13 is fixedly mounted on the abutment plate 12. An electric push rod 802 is fixedly mounted on the support block 8. The protruding end of the electric push rod 802 is slidably mounted on the lower end of the support plate 1103.

[0024] As one embodiment of the present invention, the fixed support mechanism further includes a rotating disk 14, which is rotatably installed inside the support block 8. An arc-shaped track groove 1401 is opened at equal angles on the rotating disk 14. A connecting block 13 is slidably installed in the track groove 1401. A protrusion 15 is fixedly installed on the inner wall of the rotating disk 14. The protrusion 15 is movably installed in the sliding groove 1102.

[0025] In one embodiment of the present invention, a pressing block 16 is slidably installed inside the shelf 4 by means of a spring. A movable rod 11 is fixedly connected to the upper end of the pressing block 16. The pressing block 16 is trapezoidal when viewed from the front. A movable plate 17 is elastically slidably installed inside the shelf 4. The inclined surface of the pressing block 16 abuts against the movable plate 17.

[0026] In one embodiment of the present invention, a connecting rod 18 is fixedly installed on the right end of the movable plate 17, and the upper end of the connecting rod 18 is fixedly installed on the lower end slider of the dust collection box 9.

[0027] The movable rod 11 presses down, causing the extrusion block 16 to move down synchronously. The trapezoidal extrusion block 16 pushes the moving plate 17 to slide laterally through the inclined surface. The moving plate 17 drives the dust collection box 9 to adjust the distance between it and the welding area along the platform 4 through the connecting rod 18, thereby realizing the automatic positioning of the adsorption position.

[0028] In one embodiment of the present invention, the swing adjustment mechanism includes an oil cylinder 19, which is installed inside the platform 4, and the piston rod 20 on the oil cylinder 19 is fixedly connected to the lower slider of the dust collection box 9.

[0029] As one embodiment of the present invention, the swing adjustment mechanism further includes a deflection block 21, which is installed inside the dust collection box 9. The air vent 10 is installed through the deflection block 21, and a groove 2101 is provided at the lower end of the deflection block 21.

[0030] In one embodiment of the present invention, a rotary motor 22 is fixedly installed inside the dust collection box 9, a rotating wheel 23 is fixedly installed at the output end of the rotary motor 22, and an oil cylinder 24 is fixedly installed inside the rotating wheel 23. The oil cylinder 24 and the oil cylinder 19 are interconnected through an infusion hose.

[0031] In one embodiment of the present invention, a contact rod 25 is slidably mounted on the rotating wheel 23. The upper end of the contact rod 25 is slidably mounted in the bottom groove 2101 of the deflection block 21. The contact rod 25 is connected to the piston rod 26 on the oil cylinder 24.

[0032] Working principle: First, place the fan workpiece to be welded on the support block 8. The bottom of the workpiece contacts the receiving plate 1103 at the upper end of the movable rod 11. Start the electric push rod 802 fixed on the support block 8. Its top end drives the receiving plate 1103 to move down and apply downward pressure, pushing the movable rod 11 to slide vertically down along the inside of the support block 8.

[0033] During the downward movement of the movable rod 11, the spiral groove 1101 on its surface forms a guiding fit with the limiting block 801 on the inner wall of the support block 8. The spiral groove 1101, under force, causes the movable rod 11 to rotate while sliding down. The symmetrical sliding groove 1102 on the lower surface of the movable rod 11 is movably connected to the protrusion 15 on the inner wall of the rotating disk 14. The rotation of the movable rod 11 drives the rotating disk 14 to rotate synchronously inside the support block 8. The connecting block 13 on the abutment plate 12 is slidably installed in the arc-shaped track groove 1401 with equal angles on the rotating disk 14. The rotation of the rotating disk 14, through the guiding effect of the track groove 1401 on the connecting block 13, pushes multiple sets of abutment plates 12 to expand synchronously outward along the equal-angle limiting slide rail inside the support block 8. Since the top of the abutment plate 12 is arc-shaped when viewed from above, it can fit tightly with the arc-shaped outer wall of the fan workpiece, ultimately achieving adaptive clamping of fan materials of different sizes and completing the positioning before welding. After the material is fixed, the workpiece angle can be adjusted by rotating the placement plate 7 according to welding requirements, improving welding flexibility. The rotating motor 5 fixed inside the placement table 4 is started, and its output drives the friction wheel 6 to rotate at high speed. The friction wheel 6 is in close contact with the bottom edge of the placement plate 7, driving the placement plate 7 to rotate around the rotation center of the placement table 4 through friction. The support block 8 installed on the placement plate 7 and the clamped fan workpiece rotate synchronously with the placement plate 7 until the workpiece is adjusted to the target welding angle, at which point the rotating motor 5 is turned off. Simultaneously, the welded part 3 can move horizontally along the sliding rail 2 on the welding machine base 1. Combined with the rotation angle of the workpiece, welding operations at different positions of the fan can be achieved, allowing for multi-directional welding without disassembling the material. Furthermore, while the movable rod 11 presses down to clamp the material, its lower end is fixedly connected to the extrusion block 16 inside the platform 4, causing the extrusion block 16 to slide down synchronously along the spring slide rail. The extrusion block 16 is trapezoidal when viewed from the front, and its inclined surface abuts against the elastically sliding moving plate 17 inside the platform 4. The downward movement of the extrusion block 16 pushes the moving plate 17 to move through the pressure of the inclined surface. At the same time, the connecting rod 18 at the right end of the moving plate 17 is fixedly connected to the lower slider of the dust collection box 9. The sliding of the moving plate 17 causes the dust collection box 9 to automatically adjust the distance between itself and the fan workpieces of different sizes along the slide rail of the platform 4, so that the vent 10 and the platform 4 always maintain a suitable distance. Furthermore, the movement of the dust collection box 9 causes the piston rod 20 of the oil cylinder 19, which is fixedly connected to its slider, to extend and retract. The oil cylinder 19 is connected to the oil cylinder 24 inside the dust collection box 9 through a tubing. The movement of the piston rod 20 causes the oil to flow between the two cylinders, driving the piston rod 26 of the oil cylinder 24 to slide the abutment rod 25 along the rotating wheel 23, activating the rotary motor 22 inside the dust collection box 9. Its output end drives the rotating wheel 23 to rotate, and the upper end of the abutment rod 25 slides into the groove 2101 at the bottom of the deflection block 21. The extension and retraction of the abutment rod 25 cooperates with the rotation of the rotating wheel 23, pushing the deflection block 21 to drive the vent 10 to swing at multiple angles inside the dust collection box 9. The swing angle of the vent 10 is matched in real time with the sliding trajectory of the welded part 3 and the rotation angle of the shelf 7, ensuring that the fumes generated during the welding process are always within the adsorption range of the vent 10, achieving efficient fume collection. After the welding operation is completed, the electric push rod 802 returns to its original position and retracts to its ejector end. The spring connected to the extrusion block 16 inside the platform 4 releases its elastic force, pushing the extrusion block 16 to drive the movable rod 11 to move vertically upward. During the upward movement of the movable rod 11, the cooperation between the spiral groove 1101 and the limit block 801 causes the movable rod 11 to rotate in the opposite direction. This, through the protrusion 15, drives the rotating disk 14 to rotate in the opposite direction, thereby pushing the abutment plate 12 to retract and release the pressure on the workpiece. The ejected movable rod 11 makes it easier for the staff to remove the welded fan workpiece.
