Two pairs of ears are arranged on the short sides of the bracket 1021, respectively, and the ears are connected to the lifting hydraulic cylinder 103. The bracket 1021 is covered with a plurality of strip panels 1022 at intervals. A component fine-tuning device 104 is set in the middle of the transport frame 101 where the strip panel 1022 is not covered. The component fine-tuning device 104 includes symmetrically arranged U-shaped steel plates 1041 and elastic levers 1042 on the U-shaped steel plates 1041. The U-shaped steel plates 1041 are connected to the transport frame 101 through slide rails. A hydraulic rod is set between the symmetrically arranged U-shaped steel plates 1041, which can push the U-shaped steel plates 1041 to open or close synchronously to both sides. A spring is set at the front end of the elastic lever 1042 and is fixedly set at the U-shaped opening of the U-shaped steel plate 1041. An anchor device 4 is set on the side of the transport frame 101, and the anchor device 4 includes a hydraulic cylinder connected to the side of the transport frame 101 and an anchor rod 401 connected to the hydraulic cylinder. An anchor hole 402 is set on the ground corresponding to the anchor rod 401. When the transport frame 101 runs into place and needs to be fixed, the anchor rod 401 is pushed down by the hydraulic cylinder and inserted into the anchor hole 402 on the ground. The front end of the anchor rod 401 is conical. When falling into the anchor hole 402, even if there is a slight error, it can be calibrated through the conical structure to achieve the effect of fixing the feeding and conveying mechanism 1.

[0036] like Figure 3 , Figure 6 and Fig.10As shown, the pick-and-place mechanism 2 includes a base 201, a rectangular frame 202 and a gripping device 203, wherein the base 201 is fixedly arranged on both sides of the track, and a lifting rod 2011 and a telescopic lever 2012 are respectively arranged in the base 201 on both sides, and the lifting rod 2011 and the telescopic lever 2012 are driven by a hydraulic cylinder.

A spring is arranged at the bare rod, and the threads are fastened by a nut. When grabbing components, the spring structure at the front end can buffer the downward force and protect the suction cup 2033 and the components.

[0037] like Figure 4 , Figure 7 and Figure 8 As shown, the stacking and conveying mechanism 3 includes a transport frame 301 and a stacking device 302, wherein a motor is arranged at the bottom of the transport frame 301 to drive the stacking and conveying mechanism 3 to run through gear transmission, and an anchor device 4 is arranged on one side of the transport frame 301, and the anchor device 4 includes a hydraulic cylinder connected to the side of the transport frame 301 and an anchor rod 401 connected to the hydraulic cylinder, and an anchor hole 402 is arranged on the ground corresponding to the anchor rod 401. When the transport frame 301 is in place and needs to be fixed, the anchor rod 401 is pushed down by the hydraulic cylinder and inserted into the anchor hole 402 on the ground. The front end of the anchor rod 401 is conical. When it falls into the anchor hole 402, even if there is a slight error, it can be calibrated through the conical structure to achieve the effect of fixing the stacking and conveying mechanism 3, and a towing plate 3011 is arranged on the other side of the transport frame 301, and the stacking device 302 is arranged on the transport frame 301. The palletizing device 302 includes a palletizing platform 3022 , a platform base 3023 and a palletizing slot 3024 on the palletizing platform 3022 . A rotating cylinder is arranged inside the platform base 3023 , and the rotating cylinder controls the rotation of the palletizing platform 3022 via a rotating shaft.

[0038] The working method is:

[0039] In the initial state, the loading and conveying mechanism 1 stacks the components on the transport pallet 102 through the front-end equipment. The components on the transport pallet 102 are not neat. If the components are transported to the bottom of the pick-up and placement mechanism 2 at this stage, the suction cup 2033 cannot complete the grasping work corresponding to the scattered components. At this time, by adjusting the height of the lifting hydraulic cylinder 103, the transport pallet 102 is lowered to lift the elastic lever 1042 on the component fine-tuning device 104 from the uncovered area in the middle of the strip panel 1022. A spring is set at the front end of the elastic lever 1042. The spring can prevent the elastic lever from rigidly contacting the components and causing damage. At this time, the U-shaped steel plate 1041 can be lifted by the hydraulic rod between the U-shaped steel plates 1041 is pushed open, driving the elastic lever 1042 to push the components to both sides of the transport pallet 102. At this time, the transport pallet 102 is lifted by the lifting hydraulic cylinder 103, and the loading and conveying mechanism 1 starts to run towards the pick-up and placement mechanism 2. At this time, the telescopic levers 2012 on both sides of the base 201 below the pick-up and placement mechanism 2 are pushed out, parallel to the components on the loading and conveying mechanism 1. As the loading and conveying mechanism 1 runs deeper, the telescopic levers 2012 align the components from the front to the back. At this time, the components on the loading and conveying mechanism 1 are in a neat state and can be grabbed. At this time, the anchor device 4 on one side of the loading and conveying mechanism 1 pushes the anchor rod 401 into the anchor hole 402 through the hydraulic cylinder to complete the fixation.

[0040] When the gripping device 203 of the picking and placing mechanism 2 is in the initial state, it is lifted to the highest point. When the loading and conveying mechanism 1 is completed, the lifting rod 2011 on the base 201 pulls the hinged lifting frame 2031 down to a suitable height, and the two-way hydraulic cylinder 2034 on the push-pull frame 2032 adjusts the position of the push-pull frame 2032 to correspond to the component on the loading and conveying mechanism 1. At this time, the lifting frame 2031 descends, so that the suction cup 2033 completes contact with the component. When in contact, the spring on the suction cup completes the buffering to protect the safety of the suction cup 2033 and the component, and the air in the suction cup is emptied through the air hole in the middle of the suction cup 2033 to achieve a vacuum adsorption state. At this time, the suction cup 2033 has firmly grasped the component, and the lifting frame 2031 is pushed up by the lifting rod 2011. At this time, the loading and conveying mechanism 1 is withdrawn from under the picking and placing mechanism 2, and the stacking conveying mechanism 3 is operated to under the picking and placing mechanism 2.

[0041] The stacking conveying mechanism 3 is away from the pick-up and placement mechanism 2 in the initial state. When the feeding conveying mechanism 1 is finished working, the stacking conveying mechanism 3 runs to the bottom of the pick-up and placement mechanism 2. After it is in place, the anchor rod 401 of the anchoring device 4 is directly lowered into the anchor hole 402 by the hydraulic cylinder to complete the fixation. Then the pick-up and placement mechanism 2 completes the docking of the component with the stacking slot 3024 by adjusting the position of the lifting frame 2031 and the push-pull frame 2032. It should be noted that when the short component is grabbed, one stacking slot 3024 can place one component. At this time, when the first layer is stacked, the stacking platform 3022 rotates 90 degrees to stack the next layer. The components are stacked crosswise, which is both flat and stable. When the component becomes a long component, the stacking platform 3022 does not rotate. When the stacking conveying mechanism 3 is fully loaded, the pick-up and placement mechanism 2 is returned to the initial state, and the anchoring device 4 of the stacking conveying mechanism 3 is lifted. The stacking conveying mechanism 3 can transport the component to the next device. At this time, the stacking cycle of the small component is completed and the next cycle of work can be carried out.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
