[0034] The control member 30 comprises a driving motor 32 fixedly installed in the body 1, and the model of the driving motor 32 is preferably YYHS-40, and the output end of the driving motor 32 is coaxially fixedly connected with the bottom surface of the rotating column 27, and a reciprocating screw rod 33 is rotatably connected in the body 1, and the reciprocating screw rod 33 penetrates through the guide frame 19 and is threadedly connected with the guide frame 19, and the bottom surface of the rotating column 27 is coaxially fixedly connected with a bevel gear ring 34, and one end of the reciprocating screw rod 33 is coaxially fixedly connected with a bevel gear 35, and the bevel gear 35 is engaged with the bevel gear ring 34.

[0036] Working principle: the box body frame 40 is conveyed to the second conveying belt 6 through the first conveying belt 4, at this time, one end of the second conveying belt 6 is in fit with the end of the first conveying belt 4, so as to facilitate the stable conveying of the frame 40 on the first conveying belt 4 to the second conveying belt 6, after the frame 40 reaches the middle position on the upper side of the second conveying belt 6, the running state of the second conveying belt 6 is stopped, and the frame 40 and the side plate can be welded by the arc welding head 3 controlled by the mechanical arm 2, the side plate can be grabbed and installed on the frame 40 by the mechanical gripper, and the arc welding head 3 can weld the side plate around the frame 40 from the opening position on the side of the box door.

[0037] When welding is needed on the bottom surface position, the second conveying belt 6 is controlled to drive conveying, and the lifting platform 7 is controlled to move downward to a set position, so that the driving shaft 8 is below the second conveying belt 6, at this time the second conveying belt 6 conveys the frame 40 to the third conveying belt 9, which will make the frame 40 tilt and fall to the third conveying belt 9 first on the side close to the lower edge of the third conveying belt 9, and the inclination angle of the third conveying belt 9 in a stable state is 45°, when the frame 40 falls on the third conveying belt 9, it will make the third conveying belt 9 and the turnover plate 12 rotate around the driving shaft 8, compress the damping spring 15, and the rotating shaft 13 slides on the arc-shaped frame 11, at this time, due to the pressure of the frame 40, the angle between the third conveying belt 9 and the lifting platform 7 will be less than 45°, then the lifting platform 7 is slowly raised by the electric telescopic rod 39, so that the turnover plate 12 and the frame 40 as a whole keep a relatively stable state and move upward, until the driving shaft 8 is higher than the second conveying belt 6, then the driving shaft 8 is controlled to rotate, so that the third conveying belt 9 pushes the frame 40 to the second conveying belt 6 in the opposite direction, that is, the side surface close to the surface of the third conveying belt 9 is conveyed to the position close to the surface of the second conveying belt 6, and the bottom surface originally close to the second conveying belt 6 is turned to the side surface position at this time, so that the welding of the unwelded side surface can be completed by controlling the equipment to run again.

[0038] It is worth noting that: the overall operation of the turnover structure is relatively stable, the frame 40 does not need to be clamped, and the frame 40 will not be impacted and blocked during the turnover process, which reduces the damage probability of the frame 40 as a whole, after the turnover is completed, the lifting platform 7 is controlled to move downward again to reset to the set position, so that the driving shaft 8 is lower than the rotating table 5, then the rotating table 5 rotates without being blocked by the third conveying belt 9, and the driving motor 32 can drive the rotating column 27 and the rotating table 5 to make the box frame 40 on the second conveying belt 6 rotate horizontally to adjust the direction.

[0039] When the rotating column 27 rotates, it will drive the bevel gear ring 34 to drive the bevel gear 35 to rotate, the bevel gear 35 drives the reciprocating lead screw 33 to make the mounting frame 28 and the sliding frame 17 reciprocate in the horizontal direction, during the rotation of the rotating table 5 by 90°, the mounting frame 28 will complete a reciprocating movement along the reciprocating lead screw 33, and when the rotating table 5 rotates by 45°, the mounting frame 28 will move to the end of the reciprocating lead screw 33 away from the bevel gear 35 and start to slide in the opposite direction, so that when the rotating table 5 is at the position of 90°, the mounting frame 28 and the sliding frame 17 will drive the second driving roller 18 and the third driving roller 21 to move away from the rotating table 5 at the same time, avoiding the continuous wear of the outer wall of the first conveying belt 4 by the edge of the rotating table 5.

[0040] When the sliding frame 17 moves horizontally, the two ends of the third driving roller 21 will slide downward synchronously under the double guidance of the vertical sliding groove 20 and the inclined sliding groove 29, so that the distance between the first driving roller 16 and the second driving roller 18 is reduced, and the distance between the second driving roller 18, the first driving roller 16 and the third driving roller 21 is increased synchronously, so that the first conveying belt 4 is always in a taut state. When the second driving roller 18 slides horizontally, the second sliding rod 26 will slide to the side of the first sliding rod 25 synchronously. The top surfaces of the second sliding rod 26 and the first sliding rod 25 are flush, which can ensure that the inner wall of the first conveying belt 4 is always stably supported, and at the same time, the conveying of the objects on the first conveying belt 4 is not affected. Only a small section of the first conveying belt 4 around the second driving roller 18 is adjusted, which does not affect the transportation of the frame 40 on the first conveying belt 4 in the middle region between the first driving roller 16 and the second driving roller 18.

[0041] When the rotating table 5 rotates, the edge of the rotating table 5 will push the output table 37 to slide horizontally along the guide rail 36, and after the rotating table 5 is rotated, the extension spring 38 will pull the output table 37 to adhere to the edge of the rotating table 5 again. When it is needed to output the box on the second conveying belt 6, the output end of the second conveying belt 6 is rotated to the position adhering to the output table 37, and the second conveying belt 6 is started to output the box above to the output table 37, so as to complete the unloading operation.
