[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] Embodiment 1, as Figure 1 As shown, an automatic welding device for producing a sweeping robot includes an operating table 1, a clamping mechanism 2 is slidably connected to the left side of the upper end of the operating table 1, a fixing mechanism 6 is slidably connected to the right side of the upper end of the operating table 1, a transmission mechanism 7 is fixedly connected to the right side of the upper end of the operating table 1, a welding mechanism 4 is fixedly connected to the middle part of the upper end of the operating table 1, a rotating mechanism 5 is rotatably connected to the middle part of the upper end of the operating table 1, and a traction mechanism 3 is commonly arranged between the clamping mechanism 2 and the welding mechanism 4.

[0033] During the specific implementation of the above-mentioned device, the body of the sweeping robot to be welded is placed above the clamping mechanism 2, and the battery compartment of the sweeping robot is placed above the fixing mechanism 6. Then, the traction mechanism 3 is driven by the welding mechanism 4 to make the clamping mechanism 2 clamp the body and move to the right to the welding position. Then, the transmission mechanism 7 is stimulated to make the fixing mechanism 6 clamp the battery compartment and move to the left. Then, the clamping mechanism 2 is cooperated to place the battery compartment at the position on the body to be welded and fixed, and then the welding mechanism 4 is cooperated to weld and fix it. When one side of the welding is completed, the welding mechanism 4, the rotating mechanism 5 and the clamping mechanism 2 cooperate to make the body and the battery compartment driven to rotate 90 degrees, and then continue welding. The above operation is repeated until the four sides of the body and the battery compartment are welded and fixed.

[0034] See also Figure 2 and Figure 3 The upper end of the operating table 1 is symmetrically fixedly connected with guide rails 11, and a rectangular groove 113 is opened on the side where the two guide rails 11 are close to each other. The bottom walls of the inner surfaces of the two rectangular grooves 113 are rotatably connected with arc-shaped stoppers 111, and the arc-shaped stoppers 111 are fixedly connected with the inner surface of the rectangular groove 113 on one side close to the inner surface of the rectangular groove 113 and a spring 112 is fixedly connected together with the inner surface of the rectangular groove 113. The arc-shaped guide block 12 is symmetrically fixedly connected to the right side of the upper end of the operating table 1, and a rectangular fixed block is fixedly connected to the middle part of the upper end of the operating table 1. A through hole is opened on the left side of the upper end of the operating table 1.

[0035] When the welding mechanism 4 drives the clamping mechanism 2 to clamp the fuselage to move to the right through the traction mechanism 3, the clamping mechanism 2 slides on the outer surfaces of the two guide rails 11. When the clamping mechanism 2 moves to contact the arc surfaces of the two arc-shaped stops 111, the clamping mechanism 2 continues to drive the fuselage to move to the right while squeezing the arc-shaped stops 111 to both sides. At the same time, the spring 112 is compressed. When the clamping mechanism 2 moves to the position to be welded, the spring 112 returns to its original state and pushes the arc-shaped stops 111 outward. At this time, the right ends of the two arc-shaped stops 111 are in close contact with the clamping mechanism 2, clamping The holding mechanism 2 is limited as a whole; at the same time, the left end of the rectangular fixed block is tightly attached to the right side of the clamping mechanism 2 to limit the clamping mechanism 2 as a whole. When the transmission mechanism 7 drives the fixing mechanism 6 to move to the left, the fixing mechanism 6 is close to the upper ends of the two arc-shaped guide blocks 12. At the same time, the two arc-shaped guide blocks 12 cooperate with the fixing mechanism 6 to make the battery compartment to be welded be lifted upward during the movement to the left. When the battery compartment is moved to the top of the fuselage, the upper left side of the arc-shaped guide block 12 cooperates with the fixing mechanism 6 to move the battery compartment downward to the position to be welded on the fuselage, and then welding is performed.

[0036] During the operation of this embodiment, the body and battery compartment of the sweeping robot are respectively moved to the welding position through the clamping mechanism 2 and the fixing mechanism 6, and the battery compartment is placed in the position to be welded at the upper end of the body through the cooperation of the two arc-shaped guide blocks 12 and the fixing mechanism 6. Subsequently, the body and the battery compartment are driven to rotate 90 degrees during the welding process through the cooperation of the welding mechanism 4 and the rotating mechanism 5, which is convenient for welding and fixing of different surfaces. Through the automated clamping and rotating device, the position and angle of the body and the battery compartment of the sweeping robot can be accurately controlled, thereby reducing welding defects and improving welding quality.

[0037] Embodiment 2: Based on Embodiment 1, this embodiment is to achieve the effect of rotating the fuselage and the battery compartment 90 degrees during the welding process.

[0038] See also Figure 2 The welding mechanism 4 includes a hydraulic cylinder 41 fixedly connected to the middle of the upper end of the operating table 1, the output end of the hydraulic cylinder 41 is fixedly connected to a fixed plate 42, the middle of the lower end of the fixed plate 42 is fixedly connected to a laser welding head 43, and the left end of the fixed plate 42 is fixedly connected to a rack 2 44.

[0039] Specifically, when the fuselage and the battery compartment are to be welded, the hydraulic cylinder 41 is activated, and its output end pushes the fixed plate 42 downward, and then the fixed plate 42 drives the laser welding head 43 and the second rack 44 to move downward at the same time.

[0040] The laser welding head 43 mentioned above is a conventional design in the prior art, and this solution will not elaborate on its working principle in detail. Moreover, during the operation, the laser welding head 43 can adjust the laser parameters according to the required welding materials, such as the welding between the body of the sweeping robot and the battery compartment, so as to perform welding.

[0041] See also Figure 8 The traction mechanism 3 includes a tension spring 31 fixedly connected to the rear side of the upper end of the fixed plate 42, a traction rope 32 fixedly connected to the upper end of the tension spring 31, and a plurality of pulleys 33 fixedly connected to the upper end of the operating platform 1, and the middle parts of the outer surfaces of the plurality of pulleys 33 are tightly attached to the outer surface of the traction rope 32.

[0042] Furthermore, when the fixing plate 42 is pushed downward, the tension spring 31 and one end of the traction rope 32 fixed to the upper end of the tension spring 31 are driven to move downward, and at the same time, through the cooperation of a plurality of pulleys 33, the other end of the traction rope 32 is pulled to the right.

[0043] See also Figure 4 , Figure 5 and Figure 6 The clamping mechanism 2 includes a slider 21 slidably connected to the outer surface of the guide rail 11, a rack 26 is slidably connected to the upper end of the slider 21, and the left end of the rack 26 is fixedly connected to one end of the traction rope 32. A rectangular slider 24 is symmetrically slidably connected to the left side of the upper end of the slider 21, and a round rod 25 is fixedly connected to the upper ends of the two rectangular sliders 24. Semicircular clamping blocks 23 are slidably connected to the upper parts of the outer surfaces of the two round rods 25. Gears 27 are meshed on the front and rear sides of the rack 26, and gears 28 are meshed on the sides of the two gears 27 away from each other. Arc-shaped blocks 29 are fixedly connected to the middle parts of the upper ends of the two gears 28, and springs 22 are symmetrically fixedly connected to the left end of the slider 21.

[0044] When one end of the traction rope 32 fixedly connected to the rack 1 26 is driven to move to the right, it will drive the rack 1 26 to slide to the right, and then the two gears 1 27 respectively meshing with the front and rear sides of the rack 1 26 will rotate and drive the two gears 28 to rotate, and then drive the two arc-shaped blocks 29 to rotate around the axis of the gear 2 28;

[0045] For further information, see Figure 6 When the two gears 27 are driven to rotate, the rack 3 matched with the gear 27 moves toward one side close to each other through meshing, so that the two rectangular sliders 24 are driven by the rack 3 to move toward one side close to each other, and the rectangular slider 24 moves while driving the round rod 25 and the semicircular clamping block 23 on the same side to move in the same direction, clamping the body of the sweeping robot placed above the two semicircular clamping blocks 23, and when the rack 26 is continuously pulled to be flush with the right end of the slider 21, the rack 26 no longer slides, and at this time, the two semicircular clamping blocks 23 are close to each other and contact to form a complete circle, and at this time, the two arc-shaped blocks 29 are in a parallel state, and when the traction rope 32 continues to pull the rack 26 to move to the right, the rack 26 will drive the slider 21 to move to the right as a whole, and at the same time, the two springs 22 are stretched.

[0046] See also Figure 5 and Figure 6 A rectangular guide rail 211 is fixedly connected to the middle part of the upper end of the slider 21, and a square guide rail 212 is fixedly connected to the left side of the upper end of the slider 21. The outer surface of the rectangular guide rail 211 is slidably connected to the lower end of the rack 26. The lower ends of the two rectangular sliders 24 are slidably connected to the outer surface of the square guide rail 212. The two rectangular sliders 24 are symmetrically fixedly connected to the ends away from each other with springs three 241, and the other ends of the two springs three 241 on the same side are jointly fixedly connected to the upper end of the slider 21. A semicircular gear 231 is fixedly connected to the outer surface of the semicircular clamping block 23, and an arc groove 232 is fixedly connected to the lower end of the semicircular clamping block 23. The inner surface of the arc groove 232 is slidably connected to the upper part of the outer surface of the round rod 25. The two springs 22 are fixedly connected to the fixed blocks 221, and the lower ends of the two fixed blocks 221 are jointly fixedly connected to the upper end of the operating table 1. The lower right ends of the two rectangular sliders 24 are fixedly connected to the rack three.

[0047] When the right end of rack 1 26 is driven to move right by traction rope 32, rack 1 26 slides to the right along the surface of rectangular guide rail 211, thereby driving two gears 1 27 to rotate. At the same time, two gears 1 27 cooperate with two racks 3 to make the two racks 3 move toward each other, so that rectangular slider 24 drives round rod 25 and semicircular clamp 23 to move in the same direction. At this time, two semicircular gears 231 are tightly attached to form a circular gear, and two arc grooves 232 are tightly attached to form a circular guide groove. At the same time, during the movement of two rectangular sliders 24, two springs 3 241 on the same side are stretched.

[0048] When the slider 21 moves to the right and contacts the two arc-shaped blocks 111 on one side, the slider 21 is pulled to the right and pushes the arc-shaped blocks 111 toward the inner surface of the rectangular groove 113, and the spring 112 is compressed at the same time. When the slider 21 moves to the right and contacts the left end of the rectangular fixed block, the slider 21 stops moving. At this time, the two arc-shaped blocks 111 are no longer squeezed by the slider 21, and the arc-shaped blocks 111 are restored to their original state by the spring 112. Subsequently, the right ends of the two arc-shaped blocks 111 are pressed against the left end of the slider 21, so as to limit the slider 21.

[0049] Furthermore, the fixing plate 42 continues to move downward, at which time the traction rope 32 stops moving, and the tension spring 31 is stretched and deformed.

[0050] See also Figure 2 The transmission mechanism 7 includes a motor 71 fixedly connected to the upper end of the operating platform 1, and a threaded rod 72 is fixedly connected to the output end of the motor 71.

[0051] When the traction rope 32 drives the rack 26 and the slider 21 to move to the right at the same time, the motor 71 is stimulated, so that the output end of the motor 71 drives the threaded rod 72 to rotate.

[0052] See also Figure 7 The fixing mechanism 6 includes a slider 61 threadedly connected to the outer surface of the threaded rod 72, a guide block 611 is fixedly connected to the left side of the upper end of the slider 61, a square slider 62 is symmetrically slidably connected to the outer surface of the guide block 611, the upper ends of the two square sliders 62 are fixedly connected to telescopic rods 63, the upper ends of the two telescopic rods 63 are fixedly connected to Z-shaped rods 64, the upper ends of the two Z-shaped rods 64 are fixedly connected to clamping grooves 65, the two square sliders 62 are fixedly connected to a spring 4 66 on one side close to each other, and the outer surfaces of the two telescopic rods 63 are fixedly connected to a smooth rod 631 on the side away from each other.

[0053] The two clamping grooves 65 are distributed in mirror symmetry. Before the device is operated, the battery compartment to be welded is placed above the two clamping grooves 65 so that the battery compartment is automatically clamped.

[0054] Specifically, when the threaded rod 72 rotates, the slider 61 moves to the left along the surface of the guide rail 11, thereby driving the square slider 62, the telescopic rod 63, the Z-shaped rod 64, the clamping groove 65 and the battery compartment to be welded to move to the left. When the surface of the smooth rod 631 contacts the upper end of the arc-shaped guide block 12, the smooth rod 631 drives the telescopic rod 63 to move upward during the forward movement due to the shape of the arc-shaped guide block 12, and at the same time drives the Z-shaped rod 64, the clamping groove 65 and the battery to move upward.

[0055] When the slider 2 61 moves to the point where the outer surfaces of the two telescopic rods 63 are in contact with the arc-shaped surfaces of the two arc-shaped blocks 29 respectively, due to the guiding effect of the arc-shaped blocks 29 on the telescopic rods 63, the two telescopic rods 63 move forward while driving the square slider 62 to move away from each other along the arc-shaped surfaces of the arc-shaped blocks 29. At this time, the two square sliders 62 slide along the surface of the guide block 611 to the side away from each other, and at the same time, the spring 4 66 is stretched, and at the same time, the Z-shaped rod 64 and the clamping groove 65 on the same side are driven by the telescopic rod 63 to move in the same direction;

[0056] When the smooth rod 631 moves to the right side of the upper end of the arc-shaped guide block 12, it drives the clamping groove 65 and the battery compartment to move downward. At this time, the two arc-shaped blocks 29 cooperate to separate the two clamping grooves 65, so that the battery compartment to be welded falls exactly into the position of the fuselage to be welded, and then the motor 71 is reversed to move the slider 2 61 to the right.

[0057] See also Fig. 9 and Fig.10The rotating mechanism 5 includes a gear three 52 that can mesh with the rack two 44, a round roller 51 is fixedly connected to the inner surface of the gear three 52, a bevel gear one 53 is fixedly connected to the outer surface of the front end of the round roller 51, a bevel gear two 57 is meshed with the lower part of the outer surface of the bevel gear one 53, an arc gear 56 is rotatably connected to the inner surface of the bevel gear two 57, a fixed roller 55 is fixedly connected to the middle part of the upper end of the arc gear 56, and a gear four 54 is fixedly connected to the upper part of the outer surface of the fixed roller 55.

[0058] When the battery compartment is placed in the fuselage by the two clamping grooves 65 and is ready for welding, the outer surface of the semicircular gear 231 is just meshed with the outer surface of gear four 54. When the output end of the hydraulic cylinder 41 continues to push the fixed plate 42 downward, the right end of the rack two 44 is meshed with the left end of the outer surface of the gear three 52. When the rack two 44 continues to be driven by the fixed plate 42 to move downward, the surface of the rack two 44 is tightly attached to the inner surface of the through hole. The rack two 44 will drive the gear three 52 to rotate, and the round roller 51 will rotate, which will drive the bevel gear one 53 to rotate, and the bevel gear two 57 will rotate through meshing.

[0059] See also Fig.10 The inner surface of the second bevel gear 57 is symmetrically connected to a check block 571 for rotation, and the two check blocks 571 are close to each other and are in close contact with the outer surface of the arc gear 56.

[0060] Furthermore, when rack 2 44 drives gear 3 52, bevel gear 1 53 and bevel gear 2 57 to rotate downward, the two check blocks 571 slide along the surface of the arc gear 56 and will not drive the arc gear 56 to rotate. At this time, the arc gear 56, the fixed roller 55 and the gear 4 54 are not driven to rotate.

[0061] When the laser welding head 43 finishes welding one side of the fuselage and the battery compartment, the output end of the hydraulic cylinder 41 drives the laser welding head 43 and the rack 2 44 to move upward for a distance. At this time, the rack 2 44 drives the gear 3 52, the bevel gear 1 53 and the bevel gear 2 57 to rotate through meshing. At this time, the two check blocks 571 are located between the arc teeth of the arc gear 56. When the bevel gear 2 57 is driven to rotate in the opposite direction, the two check blocks 571 cooperate with the arc gear 56 to make the arc gear 56 and the bevel gear 2 57 rotate in the same direction, so that the fixed roller 55 and the gear 4 54 rotate in the same direction, and then the gear 4 54 and the semicircular gear 231 are meshed, so that the two semicircular gears 231 rotate 90 degrees in coordination.

[0062] When the semicircular gear 231 is driven to rotate by the gear 454, the two semicircular clamping blocks 23 clamp the fuselage and the battery compartment are driven to rotate in the same direction by the two semicircular gears 231. At this time, the outer surfaces of the two round rods 25 slide on the inner surfaces of the two arc grooves 232 respectively.

[0063] After the laser welding head 43 and rack 2 44 are driven up a certain distance by the fixed plate 42, the fixed plate 42 continues to drive the laser welding head 43 to descend. At this time, the two check blocks 571 cooperate with the arc gear 56 to prevent the arc gear 56, the fixed roller 55 and the gear 4 54 from rotating during the descent of the rack 2 44. Then the laser welding head 43 welds the unwelded battery compartment and the body, and then repeats the above operation. The body and the battery compartment are rotated 90 degrees through the rotation and cooperation of the two semicircular gears 231, and then welding is performed.

[0064] When all welding is completed, the output end of the hydraulic cylinder 41 drives the fixed plate 42, the laser welding head 43 and the rack 2 44 to move upward and reset. At this time, the tension spring 31 is no longer stretched, and the traction rope 32 is in a stress-free state. Then, the two arc-shaped blocks 111 are pressed and the spring 1 12 is squeezed at the same time. At this time, the two stretched springs 22 cooperate with the fixed block 221 to pull the slider 1 21 to the left. At the same time, the two springs 3 241 on the same side pull the rectangular slider 24 to move away from each other. Then the two semicircular clamps 23, the semicircular gear 231 and the arc groove 232 are separated. At this time, the fuselage and the battery compartment are no longer clamped. Remove the welded workpiece, and after all are reset, place the fuselage to be welded on the two semicircular clamps 23 again for welding.

[0065] Therefore, in this solution, the smooth rod 631 cooperates with the arc-shaped guide block 12 to make the two clamping grooves 65 move upward during the movement of the battery compartment, and at the same time, the two arc-shaped blocks 29 cooperate to separate the two telescopic rods 63 so that the battery compartment clamped by the two clamping grooves 65 falls into the part of the fuselage to be welded. The position and movement trajectory of the battery compartment can be accurately controlled to ensure that the battery compartment can be accurately placed in the designated position of the sweeping robot body, thereby improving the installation efficiency and reducing the welding problems caused by position deviation. At the same time, during the welding process, the semicircular gear 231 is used to rotate the fuselage and the battery compartment as a whole 90 degrees to ensure accurate positioning, avoid position deviation caused by human operation, and reduce the risk of accidents caused by improper human operation.

[0066] It should be noted that the specific installation method of the motor 71, the circuit connection method and the control method used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.
