[0020] By adopting the above technical solution, the slide rail of the second linear guide 103 slides laterally on the slider of the second linear guide 103, and the mesh plate swing drive device 107 drives the connecting plate 108 to move back and forth laterally, thereby driving the slide rail of the second linear guide 103 to move back and forth on the slider of the second linear guide 103. The first gear 106 meshes with the first rack 105 for transmission. In this embodiment, the mesh plate swing drive device 107 is preferably set as a cylinder.

[0021] Reference Figure 4-5 As shown, the mesh panel lifting drive mechanism 200 includes a mesh panel conveying support column 201, a third linear guide rail 203, a fourth linear guide rail 204, a lifting mounting frame 202, a reducer 206, a mesh panel lifting drive device (motor) 207, a second gear 208, and a second rack 205. The third linear guide rail 203 and the fourth linear guide rail 204 are longitudinally mounted on one side of the mesh panel conveying support column 201 and are arranged parallel to each other.

[0022] By adopting the above technical solution, the mesh conveying support column 201 is fixedly installed on the top of the first gear 106 and rotates with the first gear 106. The mesh lifting drive device 207 drives the lifting mounting frame 202 to slide up and down on the third linear guide rail 203 and the fourth linear guide rail 204 through the second gear 208 and the second rack 205. In this embodiment, the mesh lifting drive device 207 is preferably set as a servo motor 207.

[0023] Reference Figure 6-7 As shown, the mesh plate suction mechanism 300 includes a mesh plate swing frame 800, suction hanging horizontal plates 700 are respectively installed on the two ends of the mesh plate swing frame 800, and mesh plate suction components 310 are respectively installed on the two ends of the suction hanging horizontal plates 700. The mesh plate suction assembly 310 includes a guide rod mounting plate 301, two linear guide rod sleeve assemblies 303, a guide rod connecting plate 302, a rotating shaft 304, and a suction cup 305. The guide rod mounting plate 301 is horizontally mounted on the end of the suction mounting plate 700. The two linear guide rod sleeve assemblies 303 are vertically mounted on the two ends of the guide rod mounting plate 301. The guide rod connecting plate 302 is connected to the bottom of the guide rods of the two linear guide rod sleeve assemblies 303. The suction cup 305 is rotatably connected to the guide rod connecting plate 302 through the rotating shaft 304.

[0024] By adopting the above technical solution, the mesh plate swing frame 800 is installed on the lifting mounting frame 202. The mesh plate lifting drive mechanism 200 drives the suction cup 305 to move up and down. When the suction cup 305 is energized, it clamps the mesh plate 600. The suction cup 305 can swing around the guide rod connecting plate 302 via the rotating shaft 304. When individual suction cups 305 contact and press the mesh plate 600, the suction cup 305 is on the guide rod mounting plate via two linear guide rod guide sleeve assemblies 303. The height of 301 is increased to avoid the inability of some suction cups 305 to contact and pick up the mesh plate 600 due to uneven contact points between the suction cups 305 and the mesh plate 600. Based on the shape of the contact points between the mesh plate 600 and the suction cups 305, the suction cups 305 adjust their swing direction through adaptive swing to improve the fit between the suction cups 305 and the mesh plate 600, and maximize the use of the magnetic force of the suction cups 305 on the mesh plate 600, thereby improving the stability of the suction cups 305 in picking up the mesh plate 600.

[0025] Reference Figure 8-9As shown, the screen pushing mechanism 400 includes a pushing mounting plate 401, a pushing rod frame 402, a pushing rod frame tensioning drive device (cylinder) 404, a pushing rod frame clamping block 403, a first photoelectric sensor 406, and a sensor mounting base 405. The pushing rod frame 402 is slidably mounted on the pushing mounting plate 401. The pushing rod frame tensioning drive device 404 is mounted on the pushing mounting plate 401 and located on one side of the pushing rod frame 402. The pushing rod frame clamping block 403 is mounted on the output end of the pushing rod frame tensioning drive device 404. The sensor mounting base 405 is mounted on the pushing mounting plate 401 and located on the other side of the pushing rod frame 402. The first photoelectric sensor 406 is mounted on the sensor mounting base 405.

[0026] By adopting the above technical solution, the push-down mounting plate 401 is installed on the mesh swing frame 800.

The upper limit plate 408 is connected and installed on the upper end of the two push-down rods 407, and the lower push-down plate 409 is connected and installed on the lower end of the two push-down rods 407. The push-down rod frame 402 descends with the mesh suction mechanism 300. The push-down rod frame 402 descends onto the mesh 600 and is raised by the pressure of the mesh 600. When the first photoelectric sensor 406 detects the push-down rod frame 402, the push-down rod frame pushing drive device 404 drives the push-down rod frame to push down. The drop bar clamping block 403 clamps the drop bar frame 402, preventing the drop bar frame 402 from pushing the mesh plate 600 off the mesh plate suction mechanism 600 due to gravity. The mesh plate 600 is transferred to the mesh plate positioning mechanism 500. The suction cup 305 is de-energized, and the drop bar frame pushing drive device 404 drives the drop bar frame clamping block 403 to reset and release the clamping on the drop bar frame 402. Due to gravity, the drop bar frame 402 pushes the mesh plate 600 off the mesh plate suction mechanism 300 and onto the mesh plate positioning mechanism 500, preventing the suction cup 305 from sticking to the mesh plate 600 due to incomplete magnetic force dissipation. In this embodiment, the drop bar frame pushing drive device 404 is preferably set as a cylinder.

[0027] Reference Figure 10 As shown, the mesh plate stacking mechanism 900 includes a stacking base frame 901, several stacking limiting posts 902, two sensor brackets 905, and two through-beam photoelectric sensors 904; each of the several stacking limiting posts 902 has a stacking adjustment seat 903 on one end, and the several stacking limiting posts 902 are fixedly installed on the edge of the stacking base frame 901 through the stacking adjustment seats 903, and the several stacking limiting posts 902 provide lateral limiting for the mesh plate 600; Sensor brackets 905 are provided on both outer sides of the stacking base frame 901, and photoelectric sensors 904 are installed on the top of each sensor bracket 905.

[0028] By adopting the above technical solution, several stacking limiting posts 902 laterally limit the mesh plate 600, and the through-beam photoelectric sensor 904 detects whether the stacked mesh plate 600 has reached the predetermined height. When two through-beam photoelectric sensors 904 detect the mesh plate 600, the stacking of the next mesh plate 600 is immediately stopped.

[0029] Reference Figure 11 As shown, the mesh plate positioning mechanism 500 includes a mesh plate carrier plate 501, a second photoelectric sensor 509, a first mesh plate reference plate 508, a third photoelectric sensor 511, a second mesh plate reference plate 510, a first mesh plate clamping block 502, a first mesh plate pushing and driving device 503, a first mounting plate 504, a second mesh plate clamping block 505, a second mesh plate pushing and driving device 506, and a second mounting plate 507.

The second photoelectric sensor 509 is mounted on the first mesh plate reference plate 508, and the third photoelectric sensor 511 is mounted on the second mesh plate reference plate 510. The first mounting plate 504 and the second mounting plate 507 are respectively mounted on the other two adjacent ends of the mesh plate carrier plate 501.

The second mesh plate pushing drive device 506 is mounted on the second mounting plate 507. The second mesh plate pressing block 505 is mounted on the output end of the second mesh plate pushing drive device 506.

[0030] By adopting the above technical solution, the mesh plate 600 takes the first mesh plate reference plate 508 and the second mesh plate reference plate 510 as references. The first mesh plate pushing drive device 503 and the second mesh plate pushing drive device 506 respectively drive the first mesh plate pressing block 502 and the second mesh plate pressing block 505 to push the two adjacent side ends of the mesh plate 600 to limit and fix the mesh plate 600. The mesh plate 600 is accurately limited and has a good fixing effect. In this embodiment, the first mesh plate pushing drive device 503 and the second mesh plate pushing drive device 506 are preferably both set as cylinders.
