[0045] The embodiments of this application are described in detail below with reference to the accompanying drawings.

[0046] Reference Figure 1 , 2 As shown, in some embodiments of this application, a flipping and feeding mechanism is provided, including a flipping carrier 100, an adjusting component 200, and a driving component 300. The driving component 300 has a movable end 31. The flipping carrier 100 and the adjusting component 200 are mounted on the movable end 31. Specifically, the adjusting component 200 is located between the flipping carrier 100 and the driving component 300, and is used to adjust the position of the flipping carrier 100. The flipping carrier 100 includes a base 11, a loading platform 12, and a flipping motor 13. The flipping motor 13 is mounted on the base 11, and one side of the loading platform 12 is connected to the power output end of the flipping motor 13. The loading platform 12 has at least two loading sections, which are respectively located on two surfaces of the loading platform 12.

[0047] Combination Figure 3 As shown, the base 11 includes a base plate 111 and a side plate 112, with the side plate 112 erected on the base plate 111. A tilting motor 13 is mounted on the side plate 112 and connected to one side of the loading platform 12, while the other side of the loading platform 12 is rotatably connected to the side plate 112. The top of the tilting carrier 100 has an assembly station. Driven by the tilting motor 13, the loading platform 12 rotates, causing the loading parts on different surfaces of the loading platform 12 to tilt onto the assembly station. Since different loading parts can be tilted out at the same assembly station, different assembly steps can be performed at the same assembly station, reducing the use of functional equipment during assembly and effectively reducing the floor space of the production line. In addition, multiple assembly steps can be completed within the same equipment, effectively improving efficiency as workpieces do not need to be transferred between multiple machines. Compared to using a cleanroom, the cost of maintaining a clean environment within a single piece of equipment is lower.

[0048] In some embodiments of this application, reference is made to Figure 4 , 7As shown in FIG. 8, the loading platform 12 comprises an inner hollow shell 121. In the present application, the shell 121 is a cuboid, and has a plane upwardly arranged when the shell 121 is overturned. Preferably, the shell 121 is a cuboid, and two surfaces are the top surface 1211 and the bottom surface 1212 of the cuboid, respectively. The loading platform 12 is provided with a loading part on at least two surfaces adjacent to the side surfaces. The top surface 1211 and the bottom surface 1212 are surfaces adjacent to the side surface connected with the overturning motor 13. It can be understood that any one of the four surfaces adjacent to the side surface connected with the overturning motor 13 on the shell 121 can be used as the surface provided with the loading part. The shell 121 comprises but is not limited to a cuboid, and can also be a polygonal column.

[0049] The first loading part provided on the top surface 1211 comprises a stop unit and a suction cup 123, and the stop unit is used to limit the position of the first workpiece, wherein the first workpiece can be a display panel. The stop unit has at least four abutting surfaces in contact with the four surfaces of the first workpiece, and the relative position of the first workpiece is limited by the abutting surfaces in contact with the workpiece. The suction cup 123 is located within the range surrounded by the stop unit, and the suction cup 123 is used to adsorb the first workpiece and limit the separation of the first workpiece from the stop unit. For example, the stop unit comprises two L-shaped blocks, and each block can contact two adjacent surfaces of the first workpiece, and the four surfaces of the first workpiece are contacted by the two blocks.

[0050] Further, the shell 121 is provided with a jacking cylinder, the stop unit is connected with the jacking cylinder, and a clearance groove adapted to the stop unit is formed on the top surface 1211, and the stop unit is located in the clearance groove and moves relative to the outer shell of the loading platform 12. Under the pushing of the jacking cylinder, the stop unit moves relative to the top surface 1211, so that the stop unit is in a lifted state or a sunken state. When the stop unit is in the lifted state, the stop unit protrudes from the top surface 1211. In contrast, when the stop unit is in the sunken state, the stop unit is located in the loading platform 12, and more specifically, the top surface of the stop unit is not higher than the top surface 1211.

[0051] The jacking cylinder can push the stop unit to lift or sink according to the control, so that the top surface 1211 is flat when not working. When working, the lifted stop unit can effectively limit the position of the first workpiece on the top surface 1211.

[0052] Furthermore, the stop units are a first stop unit 124 and a second stop unit 125, and the lifting cylinder can independently control the movement of the first stop unit 124 and the second stop unit 125. In this design, the contour range S2 formed by the mating surface of the first stop unit 124 is located within the contour range S3 formed by the mating surface of the second stop unit 125, that is, the first workpiece size limited by the first stop unit 124 is smaller than the first workpiece size limited by the second stop unit 125. When the first stop unit 124 is in the raised state, the second stop unit 125 is in the lowered state. When the first stop unit 124 is in the lowered state, the second stop unit 125 is in the raised state.

[0053] Meanwhile, the suction cup 123 is located within the contour range S2 formed by the contact surface of the first stop unit 124. The suction cup 123 can be compatible with adsorbing various types of first workpieces of different sizes. For example, there are four suction cups 123, and the contour range S1 formed by the four suction cups 123 is located within the contour range S2 formed by the contact surface of the first stop unit.

[0054] In some embodiments of this application, reference is made to Figure 5 , 6 As shown, the surface of the loading platform 12 includes a bottom surface 1212, and the loading section includes a second loading section 122 mounted on the bottom surface 1212. The second loading section 122 is a loading tray, on which a second workpiece is loaded. The second workpiece can be a rubber ring, which includes an annular ring and centrifugal paper, with the centrifugal paper attached to the annular ring.

[0055] The second material-carrying section 122 has several material-carrying grooves and positioning posts 1225, with the positioning posts 1225 located within the contour area formed by the material-carrying grooves. An annular ring is provided corresponding to the material-carrying grooves, and positioning holes are provided on the centrifugal paper, which are adapted to the positioning posts 1225. The positioning posts 1225 are inserted into the positioning holes to position the second workpiece.

[0056] To prevent the second workpiece from separating from the positioning post 1225, an adsorption tank is also provided on the loading tray 122. The loading platform 12 has a built-in negative pressure pipeline and air holes are formed on the bottom surface 1212. The adsorption tank is connected to the air holes, so that negative pressure is generated in the adsorption tank to adsorb the second workpiece.

[0057] Further, the first stop unit 124 and the second stop unit 125 are arranged on the top surface 1211 to accommodate first workpieces of different sizes. To match the first stop unit 124 and the second stop unit 125, the carrier grooves are the first carrier groove 1221 and the second carrier groove 1223. The adsorption grooves are the first adsorption groove 1222 and the second adsorption groove 1224 corresponding to the first carrier groove 1221 and the second carrier groove 1223. The negative pressure pipeline includes the first negative pressure pipeline 126 and the second negative pressure pipeline 127, the first negative pressure pipeline 126 is arranged corresponding to the first adsorption groove 1222, and the second negative pressure pipeline 127 is arranged corresponding to the second adsorption groove 1224.

[0058] Specifically, the second carrier groove 1223 is located within the contour formed by the first carrier groove 1221, the second carrier groove 1223 is limited by the positioning column 1225 to accommodate a second workpiece of a small size, and the first carrier groove 1221 is limited by the positioning column 1225 to accommodate a second workpiece of a large size. The first adsorption groove 1222 is located between the contour formed by the second carrier groove 1223 and the contour formed by the first carrier groove 1221, and the first adsorption groove 1222 adsorbs a second workpiece of a large size. The second adsorption groove 1224 is located within the contour formed by the second carrier groove 1223, and the second adsorption groove 1224 can adsorb a second workpiece of a large size or a small size. For example, the first adsorption groove 1222 and the second adsorption groove 1224 work simultaneously to adsorb a second workpiece of a large size.

[0059] In some embodiments of the present application, the present application also provides an assembly device, which includes the turnover feeding mechanism and the pressing mechanism (not shown) provided by the above-mentioned embodiments. The pressing mechanism is loaded with a third workpiece, which can be a back plate. In this scheme, the pressing mechanism is first pressed on the carrier disc to press a second workpiece on the third workpiece (for example, a rubber ring is attached to the back plate). Then the carrier platform 12 is turned over, the pressing mechanism is pressed on the top surface 1211 to press a first workpiece on the third workpiece (for example, a display panel and a back plate are assembled), so that the second workpiece is located between the first workpiece and the third workpiece.

[0060] Further, the base 11 further includes a pressure sensor 113 arranged between the side plate 112 and the bottom plate 111. When the pressing mechanism is pressed on the workpiece of the carrier platform, the pressure can be conducted along the side plate 112 to the pressure sensor 113, so as to accurately obtain the pressing force of the two workpieces during assembly, to ensure the assembly quality and avoid damage to the workpiece.

[0061] Further, as shown in FIG. 1, the carrier platform 12 is arranged on the base 11, and the carrier platform 12 includes a top surface 1211, a bottom surface 1212, a side surface 1213, a first carrier groove 1221 and a second carrier groove 1223. Figure 1 、 2As shown, the assembly apparatus further comprises a positioning assembly 400 for positioning the workpiece on the press mechanism and / or the workpiece on the carrier platform 12. The positioning by the positioning assembly 400 can ensure the accuracy of the workpiece during assembly. For example, the positioning assembly 400 comprises a first positioner 41 and a second positioner 42, which are respectively arranged on the two sides of the driving assembly 300, and the carrier platform 12 passes above the first positioner 41 and / or the second positioner 42 during the movement of the turnover carrier 100. At the same time, the press mechanism can also be transferred to above the first positioner 41 and / or the second positioner 42.

[0062] The above embodiments are used to further illustrate the present application, but the present application is not limited to these specific embodiments.
