[0002] Flexible manufacturing line production refers to an automated production system line that can adapt to flexible production adjustments according to different rapid production needs. In order to cooperate with the normal operation of the production line, it is usually necessary to use a handling device to transport workpieces and materials. The most common handling machine is the automatic guided vehicle, that is, the AGV cart, which can automatically navigate in the factory and transport workpieces or materials.

[0003] The handling device for flexible manufacturing production lines in the prior art usually adopts AGV carts for handling during use, and during the handling process, multiple groups of workpieces and materials need to be stacked and stacked on the cart to provide a single handling total amount.

Detailed implementation manners

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] As Figures 1 to 10As shown in the figure, an embodiment of the present invention provides a handling device for a flexible manufacturing production line and a handling method thereof, including a vehicle body 1, a bracket 2 fixedly connected to the rear end of the vehicle body 1.

The connector 103 is fixedly connected to the elastic rope 102. The connection sleeve 104 is fixedly connected to the other end of the hose 101.

[0039] Embodiment 1: Stack the workpieces to be clamped on the top of the first carrier plate 6 above the bracket 2. After stacking is completed, start the hydraulic push rod 33 in the installation assembly 3 and drive the upper second carrier plate 7 to move downward, so that the second carrier plate 7 presses down on the upper part of the placed workpieces. Start the upper and lower two groups of hydraulic push assemblies 11. The electric push rods 113 in the two groups of hydraulic push assemblies 11 push the piston plate 112 to move in the storage sleeve 111 and compress the internal hydraulic oil, so that the hydraulic oil further flows into the side frame 114 and pushes the internal push rod 115 to move, and the spring 116 stretches, pushing the swing assembly 9 to swing. The two sides of each group of hydraulic push assemblies 11 move simultaneously and push the corresponding swing assembly 9, so that the swing plate 91 in the swing assembly 9 rotates around the middle shaft 92 in the preset opening 8, the torsion spring is compressed, and at the same time drives the upper and lower connected elastic limit assemblies 10 to swing and displace in space. With the simultaneous swing of the four groups of elastic limit assemblies 10, the elastic limit assemblies 10 wrap around and tighten the two sides of the workpiece from the outside, completing the top pressing, outer tightening and limiting of the workpiece. Start the vehicle body 1 to move and transport it to the destination. After reaching the destination, first start the lifting assembly 4 to lift the installation assembly 3 upward, driving the clamped and transported workpiece to reach the specified height. Then the hydraulic push assembly 11 starts to reset, releasing the outer tightening limit. The installation assembly 3 controls the second carrier plate 7 to move upward, completely releasing the limit, and the transported workpiece can be taken out.

[0040] First, by utilizing the cooperation of the hydraulic pushing component 11 and the swinging component 9, and the elastic limiting component 10 connected between the upper and lower corresponding swinging components 9, when handling workpieces, through applying downward pressure from the top to the placed materials and wrapping with four groups of elastic limiting components 10 on both sides, it adapts to the complex structural state of the workpieces, strengthens the limiting treatment for the independently placed or stacked workpieces, effectively copes with abnormal situations such as vibration during the handling process, maintains the stability of the handled workpieces, avoids the workpieces from tipping over, and the actual limiting protection operation is simple, can quickly achieve maintaining the limit, and has high handling reliability.

[0041] In addition, by once again utilizing the cooperation of the hydraulic pushing component 11 and the swinging component 9, and the elastic limiting component 10 connected between the upper and lower corresponding swinging components 9, and using the flexibility and elasticity effects of the elastic rope 102 and the hose 101, on the one hand, it adapts to the distance change between the first carrier plate 6 and the second carrier plate 7, realizes the adaptive clamping of workpieces stacked at different heights, and on the other hand, when dealing with workpieces with low structural strength, through the contact rather than the pressure fixing effect of the upper second carrier plate 7, and at the same time using the flexible wrapping and tightening on both sides, it adapts to flexible workpieces or workpieces with weak structural strength, avoids the pressure damage of the existing rigid limiting mechanism to the workpieces, greatly improves the handling adaptability, increases the types of workpieces that can be handled, and has a wider handling application range.

[0042] Embodiment 2: When loading before handling, as the workpieces are stacked and the swinging adjustment of the elastic limiting component 10 is carried out, the supporting air supply component 13 is synchronously started. The air pump 132 outputs pressure holes, and the pressurized air enters the elastic limiting component 10 through the connecting frame 133, the intermediate pipe 134, the intermediate hole 16, the internal cavity 15, the through hole 14, and the air pipe 12. And the pressurized air enters the hose 101 and blows out outward along the collar 105. As the hose 101 rotates and swings, it changes the orientation of the collar 105 and blows and cleans the outer sides of the stacked workpieces at different angles.

[0043] First, by once again utilizing the cooperation of the hydraulic pushing component 11 and the swinging component 9, and the elastic limiting component 10 connected between the upper and lower corresponding swinging components 9, and at the same time using the supporting air supply component 13 at the top, during the actual wrapping and tightening process, directly guide the pressurized air into the elastic limiting component 10, and use the hose 101 that swings in space to change the orientation of the collar 105, so as to achieve the comprehensive blowing and cleaning of both sides of the workpiece.

[0044] Among them, the installation component 3 includes an installation plate 31, a sleeve plate 32, a hydraulic push rod 33 and a connecting block 34.
