[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Reference Figure 1-5 A high-speed rotating table includes a base shell 1 and a base frame 5 for supporting the base shell 1. The base frame 5 is provided with a first group of roller conveying components 2 for conveying products, a second group of roller conveying components 4, a bearing component 3 and a feeding positioning component 12 installed on the bearing component 3. A lifting component 10 for driving the bearing component 3 to move up and down is installed below the bearing component 3. The lifting component 10 includes a lifting plate 1002 and a fixed plate 1001 installed on the base frame 5. A rotating component 11 connected to the bearing component 3 is installed on the lifting plate 1002 for driving the bearing component 3 to rotate. The rotating component 11 includes a rotatable rotating ring 1105, a main gear 1103 and a third servo motor 1104 for driving the main gear 1103 to rotate.

[0026] Through the setting of the three groups of screw rods 1004 on the lifting component 10, the lifting speed of the supporting component 3 is fast, the lifting force is large, and the lifting position is accurate. Moreover, when the rotating component 11 drives the supporting component 3 to rotate, the setting of the feeding positioning component 12 can limit the tooling plate on the supporting frame 301 so that it will not be thrown out during the rotation operation, and has extremely high stability. Through this structural design, the production rhythm of the production line that needs to change the direction of the tooling plate can be greatly improved, and it has the characteristics of high-speed and stable product transportation.

[0027] The lifting plate 1002 is provided with a plurality of synchronous wheels 1008 , and the synchronous wheels 1008 are equipped with a synchronous belt 1007 . A tensioning wheel 1009 is provided on the outside of the synchronous belt 1007 for adjusting the tension of the synchronous belt 1007 .

[0028] Through the cooperation of the synchronous wheel 1008, the synchronous belt 1007 and the tensioning wheel 1009, the three sets of screw rods 1004 can be driven to perform lifting operations at the same time. This structural design has the characteristics of fast lifting speed, strong lifting force and accurate lifting position, which enables the tooling plate to be lifted and lowered at high speed and stably.

[0029] A screw rod 1004 is passed through the fixed plate 1001 , and a nut 1003 matching the external thread of the screw rod 1004 is installed at the connection between the screw rod 1004 and the fixed plate 1001 . The end of the screw rod 1004 passes through the lifting plate 1002 and is connected to the synchronous wheel 1008 .

[0030] Furthermore, there are at least three groups of screw rods 1004, so that the up and down movement of the lifting plate 1002 is high-speed and smooth. The screw rods 1004 and the lifting plate 1002 are connected by bearings, so that the screw rods 1004 can smoothly drive the lifting plate 1002 to complete the lifting operation, which has high practicality. Through the cooperation of the screw rods 1004 and the nut 1003, the screw rods 1004 can smoothly move up and down in the fixed nut 1003, and through the cooperation of the screw rods 1004 and the nut 1003, the lifting height control is more precise, so that after the workpiece is rotated, the bearing assembly 3 can be quickly placed in parallel with the first group of roller conveyor assemblies 2 and the second group of roller conveyor assemblies 4, and then the workpiece is output, so that the bearing assembly 3 receives the next group of tooling plates loaded with workpieces for rotation.

[0031] A second servo motor 1005 is installed at the bottom of the lifting plate 1002. The output end of the second servo motor 1005 is connected to one set of synchronous wheels 1008 through a reducer. A dust cover 1006 is installed outside the synchronous wheels 1008 and the synchronous belt 1007.

[0032] The dust cover 1006 can provide a dust-proof function for the synchronous wheel 1008 and the synchronous belt 1007, preventing impurities from entering the synchronous wheel 1008 and the synchronous belt 1007 and affecting their service life and efficiency. The synchronous wheel 1008 is driven by the second servo motor 1005 to transmit the synchronous wheel 1008 and the synchronous belt 1007, thereby performing the lifting operation of the lifting plate 1002.

[0033] The rotating assembly 11 further includes a fixed ring 1101 mounted on the lifting plate 1002 . A bearing ring 1102 is disposed outside the fixed ring 1101 . The outer wall of the bearing ring 1102 is connected to the inner wall of the rotating ring 1105 .

[0034] The rotating ring 1105 forms a rotating structure through the bearing ring 1102 and the fixed ring 1101, so that the rotating ring 1105 can rotate smoothly on the lifting plate 1002.

[0035] The outer wall of the rotating ring 1105 is provided with teeth and grooves, which mesh with the teeth and grooves on the outer side of the main gear 1103 .

[0036] After the main gear 1103 is driven to rotate by the third servo motor 1104 , it can smoothly drive the rotating ring 1105 to rotate, thereby driving the lifting plate 1002 to rotate, completing the rotation operation of the tooling plate.

[0037] The carrying assembly 3 includes a carrying frame 301 and a conveying roller 302 arranged in the carrying frame 301. A first sprocket 303 is installed at the connection between the outer end of the conveying roller 302 and the carrying frame 301. The feeding positioning assembly 12 is distributed at the four corners outside the carrying frame 301.

[0038] Furthermore, the feed positioning assembly 12 includes a rotating shaft mounted on the supporting frame 301 , a limit plate is movably mounted on the other end of the rotating shaft, and a weight block that can press down the limit plate is mounted on the end of the limit plate away from the supporting frame 301 .

[0039] Specifically, the four groups of feed positioning components 12 are arranged clockwise and / or counterclockwise at the four corners of the supporting frame 301, and one group of feed positioning components 12 will be lifted up by the spaced side plates when it descends on the side of the feed end, so that the feed positioning components 12 at this position will be in a parallel state with the supporting frame 301 as a whole, so that the tooling plate can smoothly enter the supporting frame 301, and the feed positioning components 12 at other positions will be pressed down by the weight block, so that the feed positioning components 12 will be in an inclined state as a whole, thereby limiting the tooling plate, so that the tooling plate will not be thrown out during rotation, which has high practicality; the conveying roller 302 is parallel to the second sprocket 9 on the second group of roller conveying components 4, so that when the conveying roller 302 is not rising, it shares a transmission chain 8 with the second sprocket 9 to realize the transmission function, so that it can assist the tooling plate in feeding / discharging operations, which is beneficial to improving the production efficiency of the production line.

[0040] A rotating rod 13 is installed on the base frame 5 along the conveying direction. A first servo motor 6 is installed on one side below the rotating rod 13. A second sprocket 9 is installed on the rotating rod 13. A driving sprocket 7 is installed on the output end of the first servo motor 6.

[0041] The rotating rod 13 and the base frame 5 are movably installed, so that the second sprocket 9 and the driving sprocket 7 on the rotating rod 13 can smoothly perform transmission operations, thereby allowing the rollers of the first group of roller conveying assemblies 2 and the second group of roller conveying assemblies 4 to rotate smoothly and transport and / or output the tooling plates.

[0042] A matching transmission chain 8 is arranged between the second sprocket 9 and the first group of roller conveying components 2, the first sprocket 303 on the second group of roller conveying components 4, and the first sprocket 303 on the bearing component 3. A transmission chain 8 is matched with the driving sprocket 7 on the output end of the first servo motor 6 and one of the second sprockets 9 on the rotating rod 13.

[0043] Furthermore, a tensioning sprocket is arranged on the transmission chain 8 that cooperates with the first sprocket 303 on the second group of roller conveying components 4, so that when the first sprocket 303 parallel to the second group of roller conveying components 4 descends, it can smoothly cooperate with the transmission chain 8 to perform transmission operations and assist the tooling plate in input / output work.

[0044] The working principle and use process of the present invention are as follows: through the cooperation of one of the second roller conveying assemblies 4 and the first roller conveying assemblies 2, the tooling plate loaded with the workpiece is transported to the carrying assembly 3, and the tooling plate is limited by the feed positioning assembly 12 provided on the carrying assembly 3. Then, the second servo motor 1005 on the lifting assembly 10 works to make the three sets of screw rods 1004 cooperate with the nuts 1003 on the fixed plate 1001 to push the lifting plate 1002 to complete the lifting action. The lifting speed of this structure is fast, the lifting force is large, and the lifting position is accurate. Again, the main gear 1103 is driven to rotate by the third servo motor 1104 and the reducer on the rotating assembly 11, so that the main gear 1103 drives the rotating ring 110 meshing with it. 5 performs high-speed rotation operation. At the same time, due to the function of the feeding positioning component 12, the tooling plate is not thrown out during high-speed rotation, thereby improving the production safety of the workpiece. Then, the carrying component 3 is driven down by the lifting component 10 to be parallel to the first group of roller conveying components 2 and the second group of roller conveying components 4, so that the first sprocket 303 on the conveying roller 302 on the carrying component 3 contacts and cooperates with the transmission chain 8 at the corresponding position, driving the conveying roller 302 to transmit, and conveying the tooling plate on the carrying component 3 to the other group of the second group of roller conveying components 4, and the tooling plate loaded with the workpiece is output, so that the carrying component 3 can receive the next group of tooling plates loaded with workpieces for rotation operation, and this cycle is repeated, thereby helping to improve the production rhythm speed of the air-conditioning outdoor unit production line.

[0045] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
