DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0034] Embodiment 1: The present invention provides a welding device for processing a heat dissipation fan, such as Figures 1 to 9 As shown, it includes a bracket 1, a cylinder 2 is fixedly installed on the top of the bracket 1, an extrusion piece 3 is fixedly installed on the output end of the cylinder 2, a welding robot 4 is installed on the back edge of the bracket 1, a drive shaft 6 is installed inside the bracket 1 at one end of the extrusion piece 3, a support rod 7 is fixedly installed on the top of the drive shaft 6, a limit plate 8 is fixedly installed on the top of the support rod 7, and a blade placement component 9 is movably connected to the outer side of the drive shaft 6;

[0035] The blade placement assembly 9 includes a blade placement disk 91 movably connected to the outer side of the drive shaft 6, a fixed ring 92 is fixedly installed at the bottom end of the blade placement disk 91, and a movable ring 93 is rotatably connected to the bottom end of the inner wall of the fixed ring 92, an electric telescopic rod 94 is fixedly installed at the bottom end of the movable ring 93, and the fixed end of the electric telescopic rod 94 and the top end of the bracket 1 are fixedly connected, and a plurality of positioning sleeves 95 are equidistantly welded at the bottom end of the blade placement disk 91. The number of positioning sleeves 95 is set to four and is symmetrically distributed around the center point of the blade placement disk 91, so as to keep the blade placement disk 91 stable, and a piston 96 fixedly installed at the bottom end of the support rod 7 is movably connected inside the positioning sleeve 95, and a connecting pipe 99 is fixedly connected to the bottom end of the positioning sleeve 95, and the air outlet end of the connecting pipe 99 is located inside the blade placement disk 91.

[0036] like Figure 7 and Figure 8 As shown, a boss 97 is fixedly mounted on the top of the piston 96, a connecting plate 98 is welded on the top of the boss 97, and the connecting plate 98 is fixedly mounted on the outside of the drive shaft 6;

[0037] The connecting plate 98 is fixed by the action of the driving shaft 6, and the boss 97 is fixed by the action of the connecting plate 98. When the boss 97 is fixed, the piston 96 is fixed. When the positioning sleeve 95 rises, since the piston 96 is stationary, the internal gas of the positioning sleeve 95 is discharged outward, thereby loosening the fan blade fixing part and the blade placement disk 91. When the positioning sleeve 95 descends, since the piston 96 is stationary, the external gas is extracted from the positioning sleeve 95, so that the fan blade fixing part and the blade placement disk 91 are fixed, thereby increasing the stability of the fan blade fixing part when it is placed, preventing the fan blade fixing part from shaking during the processing of the blade, and thereby improving the accuracy of the fan blade after production.

[0038] like Figure 4 and Figure 7 As shown, a connector 910 is fixedly installed at the top of the connecting pipe 99 and the connector 910 is installed at the bottom of the blade placement plate 91. A gas flow channel 911 is opened inside the blade placement plate 91 at a position corresponding to the top of the connector 910. A suction cup 912 is fixedly installed at the top of the gas flow channel 911 at the top of the blade placement plate 91.

[0039] When the gas flows inside the positioning sleeve 95, the gas enters the gas flow channel 911 along the connector 910 of the connecting pipe 99, and enters the suction cup 912 along the gas flow channel 911. The suction cup 912 increases the stability between the fan blade fixing part and the blade placement plate 91, preventing the fan blade fixing part from shaking.

[0040] like Figure 4 and Figure 8 As shown, one end of the connecting pipe 99 and the bottom end of the positioning sleeve 95 penetrate each other, which can facilitate the flow of gas and change the difficulty of gas flow. The maximum outer diameter of the protruding column 97 is equal to the inner diameter of the connecting pipe 99, which can facilitate the positioning of the protruding column 97 and prevent the protruding column 97 from swinging.

[0041] like Figure 4 and Figure 8 As shown, six placement grooves are provided at the top edge of the blade placement plate 91, and the shape of the connector 910 is conical, and the top diameter of the connector 910 is larger than the bottom diameter;

[0042] The connection between the connecting pipe 99 and the gas flow channel 911 can be facilitated, and the connection can be sealed to prevent gas leakage, thereby increasing the stability of gas flow.

[0043] like Figure 2 and Fig. 9As shown, a positioning assembly 10 is installed inside the blade placement disk 91, and the positioning assembly 10 includes a lifting plate 1001 movably connected to the inside of the blade placement disk 91 up and down, and a limiting groove is provided inside the blade placement disk 91. The outer side of the lifting plate 1001 and the inner wall of the limiting groove fit each other, which can facilitate the movement of the lifting plate 1001 and limit the movement of the lifting plate 1001. A plurality of columns 1002 are welded at equal distances on the top of the lifting plate 1001, and a screw rod 1003 is welded on the top of the column 1002. The outer side of the screw rod 1003 is connected to a limiting head 1004 through a thread, and an inclined angle is provided at the top edge of the limiting head 1004. The limiting head 1004 passes through the blade placement disk 91, which is convenient for the connection between the fan blade fixing part and the limiting head 1004, and changes the difficulty of connection between the two.

[0044] By rotating the limit head 1004, the limit head 1004 rotates along the outside of the screw rod 1003, and at this time moves along the outside of the screw rod 1003, and then the positioning hole of the fan blade fixing part and the outside of the limit head 1004 are fitted together, so that the fan blade fixing part cannot rotate, thereby increasing the limiting effect of the fan blade fixing part.

[0045] like Figure 2 and Fig. 9 As shown, a plurality of spring rods 1005 are symmetrically embedded and installed at the top of the lifting plate 1001, and the top of the spring rods 1005 is fixedly installed inside the blade placement plate 91, and a threaded sleeve 1006 is fixedly installed at the top edge of the lifting plate 1001, and a threaded rod 1007 is connected to the threaded sleeve 1006 through a thread.

[0046] By rotating the threaded rod 1007, the position of the threaded rod 1007 inside the threaded sleeve 1006 is changed. At this time, the length of the threaded rod 1007 and the threaded sleeve 1006 are adjusted. Since the length between the threaded rod 1007 and the threaded sleeve 1006 is increased, the distance between the lifting plate 1001 and the bottom end becomes smaller, thereby driving the distance between the limit head 1004 and the ground, which can change the distance between the limit head 1004 and the ground, reducing the difficulty of changing the distance between the limit head 1004 and the ground, and further adjusting the depth of the limit head 1004 inside the fan blade fixing part.

[0047] Working principle: During the actual use of the device, the user rotates the threaded rod 1007 to change the position of the threaded rod 1007 inside the threaded sleeve 1006. At this time, the length of the threaded rod 1007 and the threaded sleeve 1006 is adjusted. Since the length between the threaded rod 1007 and the threaded sleeve 1006 is increased, the distance between the lifting plate 1001 and the bottom end becomes smaller. Then the user places the fan blade fixing piece along the outer side of the limit plate 8 between the blade placing components 9. At this time, the gravity of the fan blade fixing piece presses the limit head 1004, and the limit head After 1004 is pressed together, the lifting plate 1001 is driven to move under the action of the screw rod 1003 and the column 1002. When the lifting plate 1001 moves, the spring rod 1005 is stretched, and then the fan blade fixing part is rotated. After the fan blade fixing part rotates, the limit head 1004 is driven to reset under the action of the reset force of the spring rod 1005, so that the limit head 1004 enters the circular hole of the fan blade fixing part, so that the fan blade fixing part is rotated for positioning, which increases the stability of the fan blade fixing part after installation and prevents the fan blade fixing part from self-rotating after installation.

[0048] Then the personnel drives the electric telescopic rod 94, and the electric telescopic rod 94 drives the movable ring 93 to move when it is running. When the movable ring 93 moves, it drives the blade placement plate 91 to descend through the fixed ring 92. At this time, the connecting plate 98 is fixed by the action of the driving shaft 6, and the protruding column 97 is fixed under the action of the connecting plate 98. When the protruding column 97 is fixed, the piston 96 is fixed. When the positioning sleeve 95 descends, since the piston 96 does not move, the external gas is extracted from the positioning sleeve 95. When the positioning sleeve 95 extracts gas, the gas fan blade fixing piece and the blade placement plate 91 enter into the space between the gas fan blade fixing piece and the blade placement plate 91. The suction cup 912 enters into the gas flow channel 911, and enters into the connector 910 along the gas flow channel 911, and finally enters into the connecting pipe 99 along the connecting pipe 99, and then enters into the positioning sleeve 95 along the connecting pipe 99, so that the fan blade fixing part and the blade placement plate 91 are adsorbed and fixed, and the problem of shaking between the fan blade fixing part and the blade placement plate 91 is prevented, thereby indirectly improving the welding accuracy between the fan blade fixing part and the blade, and the automation and gas adsorption technology reduce the interference of human operation, and improve the consistency and quality stability of the product;

[0049] Then, the blade is placed in the blade placement disk 91, and then the cylinder 2 is started. When the cylinder 2 is running, it drives the extrusion piece 3 to move. When the extrusion piece 3 moves, it squeezes the blade so that the blade and the blade placement disk 91 fit together. Then, the welding robot 4 is used for welding. Then, the personnel weld multiple blades in turn. After the welding is completed, the cylinder 2 is reset. In this process, the driving motor 5 drives the driving shaft 6 to rotate when it is running. When the driving shaft 6 rotates, it drives the support rod 7 and the limit plate 8 to rotate synchronously. At this time, the driving shaft 6 drives the connecting plate 98 to rotate. When the connecting plate 98 rotates, it drives the positioning sleeve 95 to rotate. When the positioning sleeve 95 rotates, it drives the blade placement disk 91 to rotate. When the blade placement disk 91 rotates, it drives the fixed ring 92 to rotate outside the movable ring 93, so that the position of the blade is adjusted. Then, the cylinder 2 is started again. The cylinder 2 drives the extrusion piece 3 to extrude the second blade, and then it is carried out in sequence, so that the fan blade is welded and formed;

[0050] Then, the electric telescopic rod 94 is started. When the electric telescopic rod 94 is in operation, it drives the blade placement component 9 to rise. When the blade placement component 9 rises, it drives the fan blades to rise and separate from the inner wall of the limit plate 8. At the same time, when the positioning sleeve 95 rises, since the piston 96 does not move, the gas inside the positioning sleeve 95 is discharged outward. When the gas inside the positioning sleeve 95 flows, the gas enters the gas flow channel 911 along the connector 910 of the connecting pipe 99, and enters the suction cup 912 along the gas flow channel 911, and blows from the suction cup 912 to between the fan blade fixing part and the blade placement plate 91, thereby loosening the fan blade fixing part and the blade placement plate 91, and then facilitating the removal of the welded fan blades, which greatly reduces the need for manual intervention and improves the efficiency of the operation. Since the automated operation reduces the risk of direct contact between human hands and high-temperature components, safety issues such as burns caused by high temperature are avoided, and the cooling is accelerated, which is convenient for subsequent personnel to take. It can also ensure the consistency of the strength and process of each removal, thereby avoiding product damage or quality problems caused by improper human operation.

[0051] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
