[0060] As Figures 1 to 8 shown, this embodiment provides a display assembly production line, including a frame 1, a conveying mechanism 2, and a positioning mechanism 3, a first screw-locking mechanism 4, a second screw-locking mechanism 5, and a third screw-locking mechanism 6 all arranged around the conveying mechanism 2. The conveying mechanism 2 and the positioning mechanism 3 are respectively arranged on the frame 1. The conveying mechanism 2 is used to convey the display screen 7 to the first screw-locking mechanism 4, the second screw-locking mechanism 5, and the third screw-locking mechanism 6 for screw-locking after the external display screen 7 is loaded, and unload the display screen 7 after screw-locking. The positioning mechanism 3 is used to position the display screen 7 located on the conveying mechanism 2. The first screw-locking mechanism 4, the second screw-locking mechanism 5, and the third screw-locking mechanism 6 are respectively arranged on the frame 1 and are respectively used to screw-lock the display screen 7 located on the conveying mechanism 2 and positioned by the positioning mechanism 3.

[0061] Specifically, the conveying mechanism 2 includes a first conveying mechanism 21, a second conveying mechanism 22, and a third conveying mechanism 23 connected in sequence. The first conveying mechanism 21 is used to load the external display screen 7 and convey it to the second conveying mechanism 22. The positioning mechanism 3 is located on one side of the second conveying mechanism 22. The first screw-locking mechanism 4, the second screw-locking mechanism 5, and the third screw-locking mechanism 6 are all located above the second conveying mechanism 22. The second conveying mechanism 22 is used to convey the display screen 7 after screw-locking to the third conveying mechanism 23, and the third conveying mechanism 23 is used to unload the display screen 7 after screw-locking. In this embodiment, the first conveying mechanism 21, the second conveying mechanism 22, and the third conveying mechanism 23 are all belt conveying mechanisms. After the display screen 7 reaches the end of the first conveying mechanism 21, the second conveying mechanism 22 will automatically take out the display screen 7 from the first conveying mechanism 21, and the third conveying mechanism 23 is the same. Regarding how the first conveying mechanism 21, the second conveying mechanism 22, and the third conveying mechanism 23 convey the display screen 7 and how to control the start and stop, they are all conventional means in this field and will not be elaborated here.

[0062] Specifically, the positioning mechanism 3 includes a first ejecting mechanism 31 and a second ejecting mechanism 32. The first ejecting mechanism 31 is arranged on one side of the conveying mechanism 2, and the second ejecting mechanism 32 is arranged on the other side of the conveying mechanism 2. The first ejecting mechanism 31 is used to abut against one side edge of the display screen 7 located on the conveying mechanism 2, and the second ejecting mechanism 32 is used to abut against the other side edge of the display screen 7 located on the conveying mechanism 2. In this embodiment, when the display screen 7 is transported to the second conveying mechanism 22, the second conveying mechanism 22 will pause the conveying so that the display screen 7 stops below the first screw-locking mechanism 4, the second screw-locking mechanism 5 and the third screw-locking mechanism 6. After the display screen 7 stops, the first ejecting mechanism 31 abuts against one side edge of the display screen 7 and pushes the display screen 7 until the other side edge of the display screen 7 abuts against the side wall of the second conveying mechanism 22, thereby completing the positioning of the display screen 7 and increasing the accuracy of the first screw-locking mechanism 4, the second screw-locking mechanism 5 and the third screw-locking mechanism 6 for screwing the display screen 7. After the display screen 7 is screwed, the first ejecting mechanism 31 retracts, and the second ejecting mechanism 32 ejects so that the display screen 7 is separated from the side edge of the second conveying mechanism 22, avoiding scratching of the display screen 7 due to friction with the side edge of the conveying mechanism (2) during the conveying process. Then, the second conveying mechanism 22 is started to transport the display screen 7 to the third conveying mechanism 23 for blanking or the next process.

[0063] Specifically, the first ejecting mechanism 31 includes a plurality of ejecting components 311. The ejecting component 311 includes an ejecting fixed plate 312, an ejecting cylinder 313, a guiding column 314 and an ejecting member 315. The ejecting fixed plate 312 is fixedly arranged on one side of the conveying mechanism 2. The ejecting cylinder 313 is arranged on one end face of the ejecting fixed plate 312. The piston rod of the ejecting cylinder 313 penetrates through the ejecting fixed plate 312 and is connected to the ejecting member 315. The ejecting fixed plate 312 is further provided with a guiding flange 316. The guiding flange 316 accommodates a linear bearing 317. The linear bearing 317 is sleeved on the guiding column 314. One end of the guiding column 314 is connected to one end face of the ejecting fixed plate 312. In this embodiment, the ejecting cylinder 313 ejects the ejecting member 315, and then the guiding column 314 guides and limits the ejecting direction of the ejecting member 315, so as to ensure that the ejecting member 315 is always parallel to the side edge of the display screen 7. In addition, since the guiding column 314 needs to penetrate through the guiding flange 316 frequently, the linear bearing 317 is provided to reduce the friction coefficient between the guiding column 314 and the guiding flange 316 and increase the service life of the guiding column 314.

[0064] Specifically, the second ejecting mechanism 32 includes an ejecting plate 321, an ejecting connecting member 322, and a plurality of ejecting units 323. The ejecting unit 323 is a rodless cylinder. One end of the ejecting connecting member 322 is connected to the sliding member of the rodless cylinder, and the other end of the ejecting connecting member 322 is connected to one end face of the ejecting plate 321. In this embodiment, both the number of ejecting units 323 and the number of ejecting connecting members 322 are two. The two ejecting units 323 are respectively arranged on one side of the first screw locking mechanism 4 and one side of the second screw locking mechanism 5, and the two ejecting connecting members 322 are respectively connected to both ends of the ejecting plate 321. Such an arrangement can make the forces at both ends of the ejecting plate 321 uniform, ensuring that the moving direction of the display screen 7 is always perpendicular to the second conveying mechanism 22 when the second ejecting mechanism 32 ejects the display screen 7; regarding the principle of how the rodless cylinder drives the sliding member to slide, it belongs to the prior art and will not be elaborated here.

The first screw supply box 41 and the first y-axis transverse movement mechanism 42 are both arranged on the frame 1. The first y-axis transverse movement mechanism 42 is used to drive the first x-axis transverse movement mechanism 43 to move transversely, and the driving direction of the first y-axis transverse movement mechanism 42 is perpendicular to the conveying direction of the conveying mechanism 2. A single first x-axis transverse movement mechanism 43 is used to drive a single first screw locking lifting mechanism 44 to move transversely, and the driving direction of the first x-axis transverse movement mechanism 43 is parallel to the conveying direction of the conveying mechanism 2. A single first screw locking lifting mechanism 44 is used to drive a single first screw locking device 45 to move up and down. The first screw locking device 45 is used to pick up screws from the first screw supply box 41 and to lock the screws into the display screen 7 located on the conveying mechanism 2. In this embodiment, the first screw supply box 41 contains a plurality of screws. The first screw locking device 45 adsorbs the screws in the first screw supply box 41 and locks the screws into the display screen 7. The first y-axis transverse movement mechanism 42, the first x-axis transverse movement mechanism 43, and the first screw locking lifting mechanism 44 are all driving mechanisms composed of a servo motor, a lead screw, and a lead screw nut. Regarding the principle of how the first y-axis transverse movement mechanism 42 drives the first x-axis transverse movement mechanism 43 to move transversely, how the first x-axis transverse movement mechanism 43 drives the first screw locking lifting mechanism 44 to move transversely, and how the first screw locking lifting mechanism 44 drives the first screw locking device 45 to move up and down, reference can be made to the prior art and will not be elaborated here again. In this embodiment, the number of the first x-axis transverse movement mechanisms 43, the first screw locking lifting mechanisms 44, and the first screw locking devices 45 are two respectively. During actual use, different numbers of the first x-axis transverse movement mechanisms 43, the first screw locking lifting mechanisms 44, and the first screw locking devices 45 can be assembled according to production requirements.

In this embodiment, by arranging the first x-axis side pushing mechanism 462, the first side pushing lifting mechanism 463 and the first side pushing member 464 on the second side pushing hanging frame 461, a certain installation space can be saved; the first x-axis side pushing mechanism 462 is a driving mechanism composed of a servo motor, a lead screw and a lead screw nut. Regarding the principle of how the first x-axis side pushing mechanism 462 drives the first side pushing lifting mechanism 463 to move in the x-axis direction, reference can be made to the prior art and will not be elaborated here again.

[0067] In addition, the first side pushing lifting mechanism 463 is a driving mechanism composed of a cylinder, a slide rail and a slider, and a top plate (not shown in the figure) is arranged in the extending direction of the piston rod of the cylinder, and a abutting member (not shown in the figure) for abutting against the top plate is arranged on the first side pushing member 464. When the piston rod of the cylinder extends, the first side pushing member 464 descends, the abutting member abuts against the top plate, the first side pushing member 464 stops moving, and then the first x-axis side pushing mechanism 462 pushes out the first side pushing lifting mechanism 463, so that the first rollers 465 on the first side pushing member 464 abut against the side of the display screen 7; after the display screen 7 is screwed, then control the piston rod of the cylinder to retract, and the first side pushing member 464 moves back to the initial position, so as to make way for the subsequent conveyed display screen 7.

[0068] Specifically, the second screw locking mechanism 5 includes a second screw supply box 51, a second y-axis transverse movement mechanism 52, a plurality of second x-axis transverse movement mechanisms 53, a plurality of second screw locking lifting mechanisms 54, and a plurality of second screw locking devices 55.

A single second screw locking lifting mechanism 54 is used to drive a single second screw locking device 55 to move up and down.

In this embodiment, the second screw supply box 51 contains a plurality of screws. The second screw locking device 55 adsorbs screws in the second screw supply box 51 and locks the screws into the display screen 7. The second y-axis transverse movement mechanism 52, the second x-axis transverse movement mechanism 53, and the second screw locking lifting mechanism 54 are all driving mechanisms composed of a servo motor, a lead screw, and a lead screw nut.

In this embodiment, the number of the second x-axis transverse movement mechanisms 53, the second screw locking lifting mechanisms 54, and the second screw locking devices 55 are two respectively. During actual use, different numbers of the second x-axis transverse movement mechanisms 53, the second screw locking lifting mechanisms 54, and the second screw locking devices 55 can be assembled according to production requirements.

When the display screen reaches the corresponding position, the piston rod of the cylinder extends, the second side pushing member 563 descends, and the first side pushing mechanism 46 abuts against the display screen and pushes the display screen towards the second side pushing mechanism 56, so that the second rollers 564 on the second side pushing member 563 abut against the other side edge of the display screen 7, making objects abut against all four side edges of the display screen, thereby further increasing the accuracy of the display screen 7 when locking screws; after the display screen 7 is locked with screws, then control the piston rod of the cylinder to retract, and the second side pushing member 563 moves back to the initial position, so as to convey the display screen 7 to the third conveying mechanism 23.
