When the workpiece is positioned by the device During processing, the workpiece is placed on the upper side of the rotating disk 4, and then the pushing component 501 is started. The pushing component 501 pushes the fitting component 502 to fit the surface of the workpiece, and pushes the element to the grabbing position of the flipping component 2. At this time, the flipping component 2 is started to lift the workpiece, and the flipping component 2 and the rotating disk 4 flip the workpiece. The assembly component 3 is started to process the workpiece. At this time, when the flipping component 2 grabs, it can be grabbed accurately and is not prone to skew. The flipping component 2 and the assembly component 3 have the same structure as the flipping mechanism and the assembly mechanism with a lifting motor in the comparative document, and no further elaboration is made here. The rotating disk 4 includes a mounting disk and a rotating motor. For those skilled in the art, the rotating disk 4 is prior art and no further elaboration is made here.

[0024] like Figure 3 and Figure 4As shown, the pushing component 501 includes a rotating seat 5012 fixedly connected to the inner wall of the rotating disk 4, the inner wall of the rotating seat 5012 is rotatably connected to a bidirectional lead screw 5013, the inner wall of the rotating disk 4 is fixedly connected to a driving motor 5016, one end of the bidirectional lead screw 5013 is fixedly connected to the output end of the driving motor 5016, the surface of the bidirectional lead screw 5013 is threadedly connected to two pushing nuts 5014, the upper ends of the two pushing nuts 5014 are fixedly connected to a pushing plate 5015, when it is necessary to push the workpiece to facilitate the clamping and flipping of the flipping component 2, the driving motor 5016 can be manually started at this time, and the driving motor 5016 drives the bidirectional lead screw 5013 to rotate, the surface of the bidirectional lead screw 5013 has two threads in opposite directions, when the bidirectional lead screw 5013 rotates When the two push nuts 5014 are moved closer to or away from each other, the two push nuts 5014 push the two push plates 5015 to move and push the workpiece to the center of the rotating disk 4.

Two limiting blocks 5018 are slidably connected to the inner wall of the limiting groove 5017. The two limiting blocks 5018 are fixedly connected to the two push nuts 5014 respectively. When the bidirectional lead screw 5013 rotates to drive the push nuts 5014 to move, the push nuts 5014 can easily follow the bidirectional lead screw 5013. The lever 5013 rotates at the same time, and at this time, the limit block 5018 is driven to slide on the inner wall of the limit groove 5017 by pushing the nut 5014 to move, so that the push nut 5014 is not easy to rotate when moving, and it is more stable. The inner walls on both sides of the rotating disk 4 that are parallel to each other are fixedly connected with stabilizing seats 5011, and the two-way lead screw 5013 is rotatably connected to the inner walls of the two stabilizing seats 5011. When the two-way lead screw 5013 rotates, the edge of the two-way lead screw 5013 is prone to swing. At this time, the rotation of the two-way lead screw 5013 is limited by the stabilizing seat 5011, so that the two-way lead screw 5013 is more stable and not easy to swing when rotating. The fitting component 502 is provided with two groups, and the two fitting components 502 both include a fixed connection to the pushing plate 501 5, one end of the pushing spring 5021 is fixedly connected with the bonding plate 5022. When the pushing plate 5015 is pushed close to the workpiece, the pushing plate 5015 will drive the pushing spring 5021 and the bonding plate 5022 to move. The elastic force of the pushing spring 5021 can increase the bonding effect on the workpiece. The side end of the pushing plate 5015 is fixedly connected with a telescopic rod 5023. One end of the telescopic rod 5023 is fixedly connected with the bonding plate 5022. The pushing spring 5021 is sleeved on the circumferential surface of the telescopic rod 5023. When the pushing spring 5021 pushes the bonding plate 5022 to fit the surface of the workpiece, the pushing spring 5021 is prone to lateral elastic deformation and damage. At this time, the pushing spring 5021 is supported by the telescopic rod 5023.This makes the push spring 5021 less likely to undergo lateral elastic deformation and more stable.

In the process of pushing the positioning and flipping component 2 to grab, it is damaged by contact and squeezing with the placement positioning mechanism 5. A positioning groove 603 is provided on the upper end of the rotating disk 4, and a positioning rod 601 is fixedly connected to one end of the shielding cloth 602. The positioning rod 601 slides and fits the inner wall of the positioning groove 603. The positioning rod 601 can be removed by cooperating with the positioning groove 603 to expose the gap on the inner wall of the rotating disk 4 for easy cleaning.

[0026] When the utility model is in use, when the workpiece is processed by the device, the workpiece is placed on the upper side of the rotating disk 4, and then the driving motor 5016 is manually started, and the driving motor 5016 drives the bidirectional lead screw 5013 to rotate. At this time, the two pushing nuts 5014 push the two pushing plates 5015 to move, and the pushing plates 5015 drive the pushing springs 5021 and the bonding plates 5022 to move. The elastic force of the pushing springs 5021 is used to increase the bonding effect on the workpiece. At this time, the flip assembly 2 is started to lift the workpiece, and the flip assembly 2 is turned over. Part 2 and rotating disk 4 flip the workpiece, start assembling component 3 to process the workpiece, at this time, when flipping component 2 grabs, it can grab accurately and is not prone to skew, when pushing nut 5014 to move, it will drive rotating rod 604 to move, at this time one end of shielding cloth 602 is fixed, rotating rod 604 rotates to release shielding cloth 602, shielding cloth 602 blocks the inner wall of rotating disk 4 to prevent the workpiece to be processed from falling in, and in the process of pushing positioning and flipping component 2 to grab, it contacts and squeezes with the placement positioning mechanism 5 and is damaged.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
