[0034] Working principle: During use, start the conversion motor 506. The conversion motor 506 rotates forward, and the conversion motor 506 drives the conversion driven bevel gear 505 through the conversion driving bevel gear 507 to make the conversion driving shaft 504 rotate. The conversion driving shaft 504 drives the synchronous belt 516 through the synchronous pulley 509 to make the synchronous block 515 slide away from the lifting and bearing platform 104, thereby driving the conversion plate 512 to be completely withdrawn from above the lifting and bearing platform 104; Then start the cylinder 204. The cylinder 204 contracts to pull the synchronous arm 205 upward. The synchronous arm 205 drives the docking sleeve 207 and the gear position ring 208 through the push-pull column 206 to make the lifting and bearing platform 104 rise until the limit sliding pin 105 reaches the upper position end. At this time, the upper surface of the lifting and bearing platform 104 is flush with the upper surface of the first positioning side strip 107. At the same time, the pressing frame plate 301 also rises and unfolds to the position end; Then start the conveying motor 409. The conveying motor 409 rotates forward, and the conveying motor 409 drives the conveying driven bevel gear 408 through the conveying driving bevel gear 410 to make the conveying driving shaft 406 rotate. The conversion driving shaft 504 drives the conveyor belt 411 to move through the transmission wheel 407, so that the conveyor belt 411 moves forward; First, place the back panel on the conveyor belt 411 with the installation surface facing up. As the conveyor belt 411 moves, the back panel is driven into the surface of the lifting and bearing platform 104 and is guided by the guiding strip 402 during movement. Then start the cylinder 204. The cylinder 204 extends to push the synchronous arm 205 downward. The synchronous arm 205 drives the docking sleeve 207 and the gear position ring 208 through the push-pull column 206 to make the lifting and bearing platform 104 descend until the limit sliding pin 105 reaches the lower position end. At this time, the lifting and bearing platform 104 drives the back panel to be received inside the enclosing and positioning frame 106 and positioned and aligned. At the same time, the lifting and bearing platform 104 also descends to the position end. At this time, stop the cylinder 204; Then start the conversion motor 506. The conversion motor 506 rotates in reverse, so as to drive the conversion plate 512 to return in the original direction in reverse, so that the conversion plate 512 extends into and completely covers the lifting and bearing platform 104 from above. At this time, the end of the conversion plate 512 abuts against the first positioning side strip 107; Then place the front screen frame on the conveyor belt 411 with the installation surface facing down. As the conveyor belt 411 moves, the front screen frame is guided by the guiding strip 402 during movement. Most of the front screen frame is driven into the surface of the sinking groove 513, and a small part is placed on the conveyor belt 411; Then, the conversion motor 506 is started, and the conversion motor 506 rotates forward, so as to drive the conversion plate 512 to be pulled out from above the lifting platform 104. When being pulled out, the conversion plate 512 will drive the front frame of the screen to be just above the lifting platform 104. When the conversion plate 512 is pulled out, the front frame of the screen is blocked by the second positioning side strip 108. Therefore, after the conversion plate 512 is completely pulled out, the front frame of the screen will directly fall into the enclosed positioning frame 106 for positioning, thereby covering the back panel. Then the cylinder 204 is started, and the cylinder 204 extends to push the synchronous arm 205 to continue to descend, thereby driving the frame pressing plate 301 to descend. After the frame pressing plate 301 descends, it squeezes the front frame of the screen to make it snap into the guide plate, so as to achieve installation; Then the cylinder 204 is started, and the cylinder 204 contracts to pull the synchronous arm 205 upward, so that the lifting platform 104 rises to the upper end, and the lower surface of the installed back plate is flush with the upper surface of the first positioning side strip 107; Then the conveying motor 409 is started, and the conveying motor 409 is reversed, so that the conveyor belt 411 moves in the reverse direction; Then start the conversion motor 506, and the conversion motor 506 is reversed, so that the conversion plate 512 is driven to return in the opposite direction of the original direction, so that the conversion plate 512 extends into the clearance gap above the lifting load platform 104 until the conversion plate 512 abuts against the first positioning side strip 107. Since the width of the sinking groove 513 is smaller than the width of the lifting load platform 104, when the conversion plate 512 abuts against the first positioning side strip 107, the inner side wall of the sinking groove 513 will push the back plate to the surface of the conveyor belt 411, and then be taken out by the conveyor belt 411, thereby realizing unloading.
