Before the preparation work, the electric transmission equipment 2 is used for carrying out the pipeline transmission operation on the light guide plate 3, meanwhile, staff is required to place the light guide plate 4 on the two placing frames 404, after the placement is completed, when the electric transmission equipment 2 is used for transporting the light guide plate 3 between the two light guide plates 4 according to the numerical control center, the electric transmission equipment 2 stops working, meanwhile, during the transmission process of the light guide plate 3, the position of the light guide plate 3 possibly deviates, namely, the light guide plate 3 is not parallel to the two positioning frames 205, therefore, in order to ensure that the two light guide plates 4 are precisely pressed on the front side and the rear side of the light guide plate 3, the light guide plate 3 is required to be adjusted in a normal position, the light guide plate 3 is parallel to the two positioning frames 205, after the electric transmission equipment 2 stops working, the electric sliding rail 201 is controlled to start working, the two sliding blocks 202 are driven to slide in opposite directions through the electric sliding rail 201, even if the two fixing plates 203 slide in opposite directions, the four first driving members 204 are driven to move, and the two positioning frames 205 are synchronously driven to move in opposite directions, when the two positioning frames 205 move in opposite directions and are contacted with the front and rear sides of the light guide plate 3, if the light guide plate 3 is in a parallel state with the two positioning frames 205, that is, no adjustment is needed, if the light guide plate 3 is not in a parallel state with the two positioning frames 205, the two positioning frames 205 are contacted with the front and rear sides of the light guide plate 3, and at the same time, the two sides of the positioning frames 205 are arranged in a bent shape, so that the light guide plate 3 is adjusted to be parallel to the two positioning frames 205, then the four first driving members 204 are synchronously controlled to start working, the two positioning frames 205 are driven to move through the four first driving members 204, so that the two positioning frames 205 are separated from the light guide plate 3, and because the first driving piece 204 and the adjacent positioning frames 205 are obliquely arranged, when the two positioning frames 205 are separated from the light guide plate 3, no external force is applied to the two positioning frames, and any influence is caused, so that the fixed position of the positioned light guide plate 3 is ensured, and the offset is not generated again.
When the two fixing plates 203 move in opposite directions, the two connecting frames 401, the two second rotating rods 405 and the two L-shaped plates 408 are synchronously driven to move, so that the two placing frames 404 are driven to move in opposite directions, and the two fixing plates have the same functions and a plurality of groups of parts, wherein only one group of parts is described, in the process that the placing frames 404 move close to the light guide plate 3, that is, the lamp tube 4 moves close to the light guide plate 3, because the lamp tube 4 is formed by combining the lamp tube cover and the two LCD lamps, in the pressing process, the lamp tube cover needs to be pressed to the front side and the rear side of the light guide plate 3, in order to enable the lamp tube cover to be smoothly pressed to the front side and the rear side of the light guide plate 3, the lamp tube cover is prevented from being deformed and being unable to be pressed to the front side and the rear side of the light guide plate 3, therefore, when the lamp tube 4 contacts the expanding plate 307, the upper side of the lamp tube cover is expanded through the expanding plate 307, then the first rack 301 is synchronously meshed with the first flat gear 303, when the fixed plate 203 continues to move towards the light guide plate 3, the first rack 301 synchronously drives the first flat gear 303 to rotate, then drives the first transmission shaft 302 to rotate through the first flat gear 303, then drives the second transmission wheel 306 to rotate through the first transmission shaft 302, further drives the second transmission shaft 305 to rotate through the second transmission wheel 306, namely drives the expanding plate 307 to rotate through the second transmission shaft 305, so that the expanding plate 307 is separated from the light tube 4, and rotates to a position which does not prevent the light tube 4 from continuously moving towards the light guide plate 3, then the slider 202 continues to drive the light tube 4 to move towards the light guide plate 3, and the left side of the light tube 4 is pressed onto the light guide plate 3 first, so that the problem that dislocation can exist when the light tube 4 is pressed onto the light guide plate 3 in parallel is effectively solved, the lamp tube 4 forced to be pressed onto the light guide plate 3 is crushed or the deformation degree of the tube cover is large, the lamp tube 4 cannot be effectively spread and supported, the lamp tube 4 is damaged due to the fact that forced pressing is not carried out on the lamp tube 4, after the left side of the lamp tube 4 is pressed onto the light guide plate 3, the electric sliding rail 201 is stopped, then the second driving piece 403 is controlled to start working, the right side of the placing frame 404 is pushed by the second driving piece 403, the placing frame 404 rotates around the second rotating rod 405, the placing frame 404 is gradually rotated to be parallel to the light guide plate 3, namely, the lamp tube 4 is gradually rotated to be parallel to the light guide plate 3, the position of the placing frame 404 after rotation is positioned by the positioning plate 406, when the placing frame 404 rotates to be in contact with the positioning plate 406, the lamp tube 4 is rotated to be parallel to the light guide plate 3, then the second driving piece 403 is controlled to stop working, meanwhile, the electric sliding rail 201 is controlled to start working again, and the sliding block 202 is controlled to continuously drive the lamp tube 4 to move close to the light guide plate 3, and the lamp tube 3 is gradually pressed to the front side and the rear side of the light guide plate 3.
Further, when the two fixing plates 203 move in opposite directions, the two air bars 5013 are synchronously driven to compress the air inside the two hollow tubes 501, so that the inside of the two hollow tubes 501 is in a high pressure state, in the process that the lamp tube 4 is gradually pressed onto the light guide plate 3, the second rack 5014 is synchronously meshed with the second flat gear 5011, and the second flat gear 5011 is driven to rotate, that is, the second flat gear 5011 drives the third rotating rod 5010 to rotate, and then the third rotating rod 5010 drives the separating disc 5012 to rotate, so that the inside of the two hollow tubes 501 is in a communicating state, and then the air pressure inside the four hollow plates 503 is synchronously increased, and then under the action of the air pressure, the four pushing plates 506 gradually slide out from the four hollow plates 503, and then the two first attaching plates 508 and the two second attaching plates 509 are driven to move towards the upper surface and the lower surface close to the tube cover of the lamp tube 4, and the upper surface and the lower surface of the tube cover of the lamp tube 4 are synchronously extruded, so that the tube cover of the lamp tube 4 is tightly attached to the light guide plate 3, meanwhile, in order to prevent the two first attaching plates 508 and the two second attaching plates 509 from excessively pressing the light guide plate 3 to damage the light guide plate 3, therefore, the two first attaching plates 508 and the two second attaching plates 509 are movably connected with the adjacent connecting plates 507 by adopting torsion springs, a certain buffering effect is achieved, after the pressing is finished, the two sliding blocks 202 are controlled to bring relevant parts back to the original position, then the electric transmission equipment 2 continues to transmit the next light guide plate 3 to the appointed position, and the lamp tube 4 is manually placed on the two placing frames 404 again, so that the flow production is realized, the efficiency is improved, and the burden of workers is lightened.
