Description

Technical Field

[0001] The present invention relates to the technical field of building board conveying, and in particular to a building board conveying device with a protective function. Background Art

[0002] Building panels mainly include solid wood boards, decorative boards, artificial boards, stone boards and glass boards. Among them, glass boards are usually used in glass curtain walls, interior partitions, skylights and other places due to their transparency and aesthetics. After the production of the panels is completed, the panels need to be transported to different workshops or different storage locations.

[0003] The existing glass plate handling device is only composed of a chassis, a moving wheel set and a fixed frame. When handling the glass plates, in order to ensure the handling efficiency, the operator will stack multiple glass plates together and place them on the chassis at an angle, and then fix the glass plates. However, since the glass plates are placed at an angle, most of the glass plates' own weight acts on the lower side of the glass plates, resulting in uneven force on the plates themselves and more concentrated force on the lower side. As a result, the plates are more likely to be broken on the lower side due to bumps or deviations during handling, thereby affecting the later use of the glass plates. Summary of the invention

The second plates 3 on the right are rotatably connected to the rotating shaft 7 through the connecting blocks. The rotating shaft 7 is fixedly connected to the blocking plate 8. The blocking plate 8 is used to intercept the right side of the glass to prevent the glass from sliding off. A torsion spring is connected between the rotating shaft 7 and the connecting block on the adjacent second plate 3. The torsion spring is used to drive the blocking plate 8 to reset. A moving mechanism for making adjacent equally spaced supporting plates 5 extend out is provided on the second plate 3. A trigger mechanism for controlling the movement of symmetrically distributed blocking plates 8 is provided on the transfer vehicle 1. A transfer mechanism for controlling the lifting of the plate is provided on the side of the transfer vehicle 1 away from the third plate 4.

[0039] Combination Figure 5 and Figure 6As shown, the moving mechanism includes a first frame 201, which is slidably connected to the lower side of the adjacent second plate 3, and a spring is connected between the first frame 201 and the adjacent second plate 3, and the spring is used to drive the adjacent first frame 201 to reset, and the first frame 201 is fixedly connected to the lowermost supporting plate 5 on the adjacent first plate 2, and the second plate 3 is slidably connected to four second frames 202 distributed at equal intervals, and the sum of the number of the equally distributed second frames 202 and the first frame 201 is equal to the number of the equally distributed supporting plates 5, and a spring is connected between the second frame 202 and the adjacent second plate 3, and the spring is used to drive the adjacent second frame 202 to reset, and the second frame 202 is fixedly connected to the adjacent supporting plate 5 on the adjacent first plate 2 (the supporting plate 5 does not include the lowermost supporting plate 5), and the first frame 201 is squeezed and matched with the adjacent second frame 202, and the first frame 201 moves vertically and squeezes the adjacent second frame 202, so that the adjacent second frame 202 moves laterally, and the two adjacent second frames 202 are squeezed and matched with each other.

[0040] Combination Figure 3 and Figure 7 As shown, the trigger mechanism includes two symmetrically distributed trigger telescopic rods 301, both of which are fixedly connected to the upper side of the transfer vehicle 1, and the trigger telescopic rods 301 are filled with hydraulic oil. The second plate 3 on the right is fixedly connected with an arc-shaped telescopic rod 302, and the arc-shaped telescopic rod 302 is filled with hydraulic oil. The arc-shaped telescopic rod 302 is connected with the adjacent trigger telescopic rod 301, and the two trigger telescopic rods 301 are located between the two arc-shaped telescopic rods 302. The telescopic ends of the arc-shaped telescopic rods 302 are fixedly connected with fixed blocks 303, and the fixed blocks 303 are fixedly connected to the adjacent blocking plate 8.

[0041] Combination Figure 1 , Figure 2 , Figure 8 and Fig. 9As shown, the transfer mechanism includes two symmetrically distributed fixed plates 401, the two fixed plates 401 are fixedly connected to the right side of the transfer vehicle 1, and the two fixed plates 401 are jointly installed with a lifting frame 402, and the lifting frame 402 is an existing lifting device, including but not limited to a scissor-type lifting frame, and a supporting frame 403 is arranged on the upper side of the lifting frame 402, and the supporting frame 403 is slidably connected to a sliding frame 404, and a driving device is arranged on the supporting frame 403, and the driving device is used to drive the sliding frame 404 to slide, and the driving device includes a servo motor, a threaded rod, a pulley and a belt, wherein the supporting frame 403 is fixedly connected to the servo motor, the supporting frame 403 is rotatably connected to the threaded rod, and the threaded rod is screwed to the sliding frame 404. The output shaft of the servo motor is connected to the threaded rod through a pulley and a belt drive. Two symmetrically distributed first limit plates 405 and two symmetrically distributed second limit plates 406 are slidably connected on the sliding frame 404. Three groups of symmetrically distributed inclined surfaces are arranged on the lower side of the first limit plate 405, and three trapezoidal blocks are arranged on the upper side of the second limit plate 406. The inclined surface of the first limit plate 405 is squeezed and matched with the trapezoidal block of the adjacent second limit plate 406, and the second limit plate 406 is squeezed and matched with the third plate 4. The telescopic ends of the symmetrically distributed trigger telescopic rods 301 are squeezed and matched with the sliding frame 404, and the symmetrically distributed second limit plates 406 are squeezed and matched with the supporting frame 403.

[0042] Since the glass plate is placed at an angle, most of its own weight acts on the lower side of the glass plate, resulting in uneven force on the plate itself and concentrated force on the lower side. As a result, the lower side of the plate is more likely to break due to bumps or deviations during transportation, thus affecting the later use of the glass plate.

[0043] When transporting glass plates, the operator first moves the device to the place where the glass plates are stacked, and places the glass plates (hereinafter referred to as glass) on the upper side of the two first limit plates 405. At this time, the first limit plates 405 are supported by the adjacent second limit plates 406 and cannot move downward. After the glass is placed on the two first limit plates 405, the operator turns on the lifting frame 402, and the lifting frame 402 begins to lift upward. The lifting frame 402 drives the supporting frame 403 to move upward, and the supporting frame 403 drives the sliding frame 404 to move upward. The sliding frame 404 drives the two first limit plates 405 and the two second limit plates 406 thereon to move upward, and the two first limit plates 405 drive the glass placed thereon to move upward.

[0044] During the upward movement of the support frame 403, when the upper side of the sliding frame 404 is flush with the upper side of the two lowest supporting plates 5, the operator closes the lifting frame 402. At this time, the height of the glass is higher than the height of the upper side of the two lowest supporting plates 5. Then the operator controls the servo motor in the driving device. The output shaft of the servo motor rotates and drives the threaded rod to rotate through the pulley belt. The threaded rod rotates and drives the sliding frame 404 to move to the left. The sliding frame 404 drives the two first limit plates 405 and the two second limit plates 406 thereon to move to the left and drive the glass thereon into the frame for holding the glass. During the movement of the two second limit plates 406 to the left, when the two second limit plates 406 are in contact with the third plate 4, the two second limit plates 406 stop moving to the left and contact the sliding frame 404 and The two first limit plates 405 move relative to each other. During the relative movement of the second limit plate 406 and the adjacent first limit plate 405, the second limit plate 406 gradually loses support for the adjacent first limit plate 405. The first limit plate 405 moves downward along the inclined surface of the trapezoidal block on the adjacent second limit plate 406, and drives the glass to move downward. After losing contact with the inclined surface of the second limit plate 406, the glass falls to fit the rotating rollers 6 on the upper side surfaces of the two lowest support plates 5. In this way, the two first limit plates 405 lose support for the glass. During this process, the sliding frame 404 always moves to the left. After the sliding frame 404 also contacts the third plate 4, the operator controls the servo motor of the driving device to rotate in the opposite direction, and the sliding frame 404 moves to the right and returns to its original position. At this time, the placement of the first piece of glass has been completed.

[0045] After the first piece of glass is placed, the glass squeezes the two lowermost supporting plates 5, the two supporting plates 5 squeeze the adjacent first frame 201, the first frame 201 moves downward and compresses the adjacent spring, the first frame 201 squeezes the second frame 202 adjacent to its upper side (taking the parts on the first plate 2 on the front side and the second plate 3 on the right front side as examples), the second frame 202 moves backward under pressure and squeezes the adjacent spring, the second frame 202 drives the adjacent supporting plate 5 to move backward, the supporting plate 5 protrudes out of the adjacent first plate 2, and the working principles of the rear first plate 2 and all the parts thereon are the same as described above.

[0046] After the two supporting plates 5 of the second layer are extended, the operator repeats the above process of transferring glass and places the second piece of glass on the two supporting plates 5 of the second layer. After placing the second piece of glass, the second piece of glass squeezes the two supporting plates 5 of the second layer to move downward, and the two supporting plates 5 of the second layer drive the adjacent second frames 202 to move downward and squeeze the adjacent springs. The second frames 202 squeeze the adjacent second frames 202 to move the adjacent second frames 202 backward, thereby making the two supporting plates 5 of the third layer extend out, and repeat this process until the two supporting plates 5 of each layer are placed with glass.

[0047] After the glass is placed on the two uppermost supporting plates 5, the operator controls the driving device to restore the sliding frame 404 to its original position, and then controls the lifting frame 402, which drives the supporting frame 403 to move upward. When the sliding frame 404 is aligned with the telescopic ends of the two trigger telescopic rods 301, the lifting frame 402 is stopped and the driving device is controlled to drive the sliding frame 404 to move leftward and squeeze the telescopic ends of the two trigger telescopic rods 301, so that the telescopic ends of the trigger telescopic rods 301 contract and the hydraulic oil inside them enters the adjacent arc-shaped telescopic rods 302, and the telescopic ends of the arc-shaped telescopic rods 302 drive the adjacent fixed blocks 303 to move, and the fixed blocks 303 squeeze the adjacent blocking plates 8, and the blocking plates 8 rotate around the adjacent rotating shafts 7 and twist the adjacent torsion springs. The two blocking plates 8 rotate relative to each other and contact the glass, so as to fix the right side of the glass to prevent the glass from sliding out from the right side. In this way, the glass is fixed. By placing the glass horizontally, the contact area between the glass and the handling device is increased, so that the force on the glass is more dispersed, and the glass is prevented from being damaged by concentrated force.

[0048] After the glass is fixed, the operator pushes the transfer vehicle 1 to move to the left and drives the glass on it to move to the target position. The operator controls the driving device to move the sliding frame 404 to the right and loses the squeezing of the two trigger telescopic rods 301. The rotating shaft 7 drives the adjacent blocking plate 8 to return to its original position under the action of the adjacent torsion spring, that is, the blocking of the glass is lost. Then the operator controls the lifting frame 402 to restore the supporting frame 403 to its original position and remove the glass.

[0049] After the glass is removed, the operator controls the driving device to move the sliding frame 404 to the right and return to its original position. During the movement of the sliding frame 404 to the right, the sliding frame 404 drives the two first limit plates 405 and the two second limit plates 406 thereon to move to the right. After the second limit plates 406 contact and squeeze the supporting frame 403, the second limit plates 406 stop moving and produce relative movement with the adjacent first limit plates 405. During this process, the first limit plates 405 move upward along the inclined surface of the upper trapezoidal block of the adjacent second limit plates 406 until the sliding frame 404 returns to its original position. At this time, the two first limit plates 405 also return to their original positions. The subsequent operator repeats the above process and places the glass on the two first limit plates 405 to transport the glass again.

[0050] In the present embodiment, the symmetrically distributed first plates 2 are all fixedly connected to the transfer vehicle 1 . In the next embodiment, the symmetrically distributed first plates 2 are rotatably connected to the transfer vehicle 1 via the support rods 503 .

[0051] Example 2: Based on Example 1, Fig.10 and Fig.11As shown, it also includes a swing mechanism, which is arranged on the transfer vehicle 1. The swing mechanism is used to drive the symmetrically distributed first plate 2 to deflect, and the swing mechanism includes two symmetrically distributed fixed seats 501, and the symmetrically distributed fixed seats 501 are respectively fixed to the upper sides of adjacent first plates 2. Sliding blocks 502 are arranged on the upper sides of the two fixed seats 501, and the two sliding blocks 502 are commonly fixed to a support rod 503. The support rod 503 is rotatably connected to the transfer vehicle 1, and an adjustment component for controlling the deflection angle of the symmetrically distributed first plate 2 is arranged on the upper side of the transfer vehicle 1. By rotatably connecting the support rod 503 to the transfer vehicle 1, the symmetrically distributed first plate 2 is kept vertical to the horizontal plane under the action of its own gravity.

[0052] Combination Figure 11-13 As shown, the adjustment component includes a U-shaped frame 504, which is fixed to the upper side of the transfer vehicle 1. The U-shaped frame 504 is fixed with two symmetrically distributed arc sleeves 505, and the arc sleeves 505 are filled with hydraulic oil. Two symmetrically distributed arc rods 506 are slidably connected in the arc sleeves 505, and the lower sides of the symmetrically distributed arc rods 506 are fixed to the adjacent sliding blocks 502. The upper sides of the symmetrically distributed arc rods 506 are commonly fixed with a first sliding frame 5061, and the first sliding frame 5061 is slidably connected to the adjacent arc sleeves 505. The first sliding frame 5061 is rotatably connected with the first inner rotating shell 5062, and a torsion spring is connected between the two, which is used to drive the adjacent first inner rotating shell 5062 to reset, and the first sliding frame 5061 and the first inner rotating shell 5062 are both provided with oval through holes, and the through holes of the two adjacent ones are connected The U-shaped frame 504 is well matched, and two symmetrically distributed first columns 507 are fixedly connected to the lower side of the U-shaped frame 504, and a heavy ball 508 is slidably connected to the upper side of the sliding block 502. A first outer skin 509 is fixedly connected between the first column 507 and the adjacent arc rod 506, and a first inner pull rope 5091 is fixedly connected between the heavy ball 508 and the adjacent first inner rotating shell 5062. The first inner pull rope 5091 is located in the adjacent first outer skin 509 and slides. A round rod is arranged in the first sliding frame 5061, and the first inner pull rope 5091 passes around the round rod. The first outer skin 509 and the adjacent first inner pull rope 5091 are similar to the existing brake line structure, and a symmetrically distributed arc limit plate 5021 is fixedly connected to the upper side of the first plate 2. The arc limit plate 5021 is in contact with the adjacent heavy ball 508, and the height of the symmetrically distributed arc limit plate 5021 gradually decreases from both sides to the middle.

[0053] During the movement of the transport device loaded with glass, when the transport device moves on an inclined road or a slope, for example, the left side of the transport device is higher than the right side, so that the glass on it tends to slide to the right, and the glass moves to the right and squeezes the inner wall of the transport device, causing the right side of the glass to be concentratedly stressed. The glass may be broken due to uneven or excessive stress. Therefore, the angles of the two first plates 2 are adjusted so that the two first plates 2 are always perpendicular to the horizontal plane to avoid the glass thereon from shifting. The specific operation is as follows:

[0054] In the initial state, the through hole on the first sliding frame 5061 and the through hole on the first inner rotating shell 5062 are in a blocked state, so that the first sliding frame 5061 cannot slide in the adjacent arc sleeve 505. When the left side of the transfer vehicle 1 is higher than the right side, taking all the parts on the front first plate 2 as an example, the transfer vehicle 1 drives all the parts thereon to deflect synchronously, and the first plate 2 drives the fixed seat 501 thereon to deflect through the support rod 503, and the fixed seat 501 drives the sliding block 502 thereon to deflect, and the front heavy ball 508 moves to the right under the action of gravity and stretches the adjacent first inner pull rope 5091, and the first inner pull rope 5091 slides in the adjacent first outer shell 509, and the first inner pull rope 5091 on the front side pulls the adjacent The first inner rotating shell 5062 rotates and twists the torsion spring thereon. At the same time, the first inner rotating shell 5062 drives the through hole thereon to rotate so that the through hole thereon is connected with the through hole of the adjacent first sliding frame 5061. At this time, the two first plates 2 and all parts thereon are deflected through the support rod 503 under the action of gravity and remain perpendicular to the horizontal plane. During the deflection of the first plate 2, the first plate 2 drives the fixed seat 501 thereon to deflect through the support rod 503, and the fixed seat 501 drives the adjacent sliding block 502 to deflect. The sliding block 502 drives the two arc rods 506 thereon to deflect, and the two arc rods 506 drive the adjacent first sliding frames 5061 to slide along the adjacent arc sleeves 505.

[0055] After the two first plates 2 are perpendicular to the horizontal plane, the heavy ball 508 slides to the initial position along the adjacent arc-shaped limit plates 5021 under the action of gravity. At this time, the first inner pull rope 5091 is in a relaxed state, and the first inner rotating shell 5062 rotates in the opposite direction and resets under the action of the adjacent torsion spring, and at the same time stretches the first inner pull rope 5091 to restore it to its initial state. The first inner rotating shell 5062 and the adjacent first sliding frame 5061 are restored to a blocked state. The two first plates 2 cannot rotate and remain perpendicular to the horizontal plane. By making the two first plates 2 perpendicular to the horizontal plane, the glass inside them is horizontal to the horizontal plane, thereby preventing the glass from being offset and causing force concentration on the glass, thereby causing damage to the glass.

[0056] In this embodiment, the fixed seat 501 and the adjacent sliding block 502 are fixedly connected. In the following embodiments, the fixed seat 501 and the adjacent sliding block 502 are slidably connected.

The sliding rod 602 on the left is fixedly connected to the adjacent fixed seat 501. The left and right sides of the second sliding frame 6021 are connected with springs between the adjacent straight sleeve 601, and the spring is used to drive the adjacent second sliding frame 6021 to reset. The fixed seat 501 is slidably connected to the adjacent sliding block 502. The second sliding frame 6021 is provided with an oval through hole, and the second sliding frame 6021 is provided with a control component for controlling its movement.

[0058] Combination Fig.15 and Fig.16 As shown, the control component includes a second inner rotating shell 6022, which is rotatably connected to the adjacent second sliding frame 6021. The second inner rotating shell 6022 is provided with an oval through hole, which is communicated and matched with the through hole of the adjacent second sliding frame 6021. The second plate 3 close to the adjacent straight sleeve 601 is fixedly connected with a second column 603, and the second plate 3 on the right side is slidably connected with a trigger frame 604, and a spring is connected between the two. The trigger frame 604 is squeezed and matched with the adjacent fixed block 303, and a second outer shell 605 is fixedly connected between the second column 603 and the adjacent sliding rod 602. A second inner pull rope 606 is fixedly connected between the second inner rotating shell 6022 and the adjacent trigger frame 604. The second inner pull rope 606 is located in the adjacent second outer shell 605 and slides. A cylinder is fixedly connected to the inside of the second sliding frame 6021, and the second inner pull rope 606 bypasses the adjacent cylinder. The second inner pull rope 606 and the adjacent second outer shell 605 are similar to the existing brake line structure.

[0059] When the transport device drives the glass on it to move, if the transport device suddenly encounters an obstacle and needs emergency braking, the glass will continue to slide in the moving direction due to inertia. At this time, the sliding glass will collide with the inner wall of the transport device. Due to the sudden concentrated force, the glass will shatter. To prevent the glass from colliding with the vehicle body due to inertia, the specific operations are as follows:

[0060] When loading glass onto each supporting plate 5, the two blocking plates 8 are in an open state and squeeze the adjacent trigger frame 604, the adjacent springs are in a compressed state, and at the same time, the through hole of the second sliding frame 6021 is not connected to the through hole of the adjacent second inner rotating shell 6022, so the second sliding frame 6021 cannot slide in the adjacent straight sleeve 601, and the sliding rod 602 cannot slide in the adjacent straight sleeve 601. At this time, the fixed seat 501 and the adjacent sliding block 502 are in a relatively static state, and the transfer vehicle 1 and the first plate 2 are also in a relatively static state. After the glass is loaded, the two blocking plates 8 are in a relatively static state. When moving, the two blocking plates 8 lose the squeezing of the adjacent trigger frame 604 respectively, and the trigger frame 604 moves to the right under the action of the adjacent spring, and the trigger frame 604 pulls the adjacent second inner pull rope 606, and the second inner pull rope 606 pulls the adjacent second inner rotating shell 6022, and the second inner rotating shell 6022 rotates and twists the adjacent torsion spring. After the second inner rotating shell 6022 rotates, the through hole on the second inner rotating shell 6022 is connected with the through hole on the adjacent second sliding frame 6021. At this time, the second sliding frame 6021 and the two adjacent sliding rods 602 can slide in the adjacent straight sleeve 601.

[0061] When the transfer vehicle 1 moves to the left, the fixed seat 501 and the adjacent sliding block 502 can slide relative to each other, and the transfer vehicle 1 and the first plate 2 can also slide relative to each other. When the transfer vehicle 1 suddenly stops moving, the two first plates 2 continue to slide to the left under the action of inertia, and the first plate 2 drives the fixed seat 501 thereon to move to the left. The fixed seat 501 squeezes the adjacent buffer telescopic rod 6011, and the spring inside the buffer telescopic rod 6011 is compressed to buffer the movement of the fixed seat 501. The fixed seat 501 pulls the left sliding rod 60 2 moves to the left, the sliding bar 602 on the left drives the adjacent second sliding frame 6021 and the adjacent sliding bar 602 on the right to move to the left synchronously. During the movement of the second sliding frame 6021, the hydraulic oil in the straight sleeve 601 passes through the through hole thereon and the through hole of the adjacent second inner rotating shell 6022, so as to buffer the movement of the second sliding frame 6021, and further buffer the movement of the fixing seat 501, so as to prevent the glass on the two first plates 2 from sliding and colliding with the inner wall of the transfer vehicle 1, resulting in glass shattering.

[0062] When the transfer vehicle 1 drives the glass thereon to move, the through hole of the second sliding frame 6021 and the through hole of the adjacent second inner rotating shell 6022 are always in a connected state, so that the two first plates 2 and the transfer vehicle 1 can always slide against each other. After the glass is moved to the target position, after the two blocking plates 8 are opened, the two blocking plates 8 squeeze the adjacent trigger frame 604 respectively, and the trigger frame 604 moves to the left and compresses the spring. At this time, the second inner pull rope 606 is in a relaxed state, and the second inner rotating shell 6022 returns to its initial position under the action of the torsion spring thereon (the second inner rotating shell 6022 and the adjacent second sliding frame 6021 are in a blocked state), and the second inner rotating shell 6022 stretches the second inner pull rope 606 to restore the second inner pull rope 606 to its initial state. At this time, the fixed seat 501 and the adjacent sliding block 502 are in a relatively static state, and the transfer vehicle 1 and the first plate 2 are also in a relatively static state. Subsequently, the operator repeats the above operation to remove the glass, and the use of this device is terminated.

[0063] Embodiment 4: Based on Embodiment 3, Figure 4 , Figure 5 and Fig.17 As shown, it also includes two symmetrically distributed fixing mechanisms, which are used to further fix the glass plate. The fixing mechanisms are arranged on five adjacent supporting plates 5 with equal spacing. The fixing mechanisms include five groups of adsorption plates 701 with equal spacing, and each group includes four evenly distributed adsorption plates 701, wherein the four groups of adsorption plates 701 are all fixedly connected to the adjacent supporting plates 5 (except the lowermost supporting plate 5). The adjacent second plates 3 on the same first plate 2 are slidably connected to four sliding rods 702 with equal spacing, and the four groups of adsorption plates 701 are respectively connected to the adjacent sliding rods 702. The movable rod 702 is slidably connected, and the first plate 2 is slidably connected with a trigger block 703, the trigger block 703 is squeezed and matched with the adjacent sliding frame 404, and the upper side of the first plate 2 is fixed with a fixed frame 704 and a support plate 705, the fixed frame 704 and the support plate 705 are both located on the upper side of the adjacent uppermost supporting plate 5, the trigger block 703 is squeezed and matched with the adjacent support plate 705, the fixed frame 704 is slidably connected with the adjacent support plate 705, and a group of adsorption plates 701 are also installed on the support plate 705, and the group of adsorption plates 701 are all slidably connected with the adjacent fixed frame 704.

[0064] During the process of extending the two supporting plates 5 of the second layer, the supporting plates 5 drive all the adsorption plates 701 thereon to move synchronously, and all the adsorption plates 701 on the same side and on the same layer drive the adjacent sliding rods 702 to slide. At this time, the adsorption plate 701 is located on the upper side of the lowermost glass (the lower side of the adsorption plate 701 is in contact with the upper side of the lowermost glass, and at this time, the length and size of the adsorption plate 701 can be changed according to the actual thickness and area of ​​the glass). Then, the operator places the glass on the two supporting plates 5 of the second layer, and the two supporting plates 5 move downward and drive all the adsorption plates 701 thereon to move synchronously. The adsorption plates 701 squeeze the lower glass, and the sliding rod 702 of the second layer does not move downward. Therefore, the sliding rod 702 of the second layer moves relative to the adjacent adsorption plates 701. At this time, the cavity space formed by the sliding rod 702, the adsorption plate 701 and the glass increases, and a negative pressure state is formed inside it.

[0065] After placing the glass on the two uppermost supporting plates 5, the operator controls the lifting frame 402 to align the sliding frame 404 with the adjacent trigger block 703, and controls the driving device to drive the sliding frame 404 to move to the left and squeeze the adjacent trigger block 703, the trigger block 703 moves and squeezes the support plate 705, the support plate 705 moves downward and makes the adsorption disk 701 thereon contact and squeeze the glass on the lower side, and at the same time, the adsorption disk 701 on the support plate 705 slides relative to the fixed frame 704, so that the volume of the cavity composed of the adsorption disk 701 on the support plate 705, the fixed frame 704 and the glass increases, and a negative pressure state is also formed inside the cavity, and the glass on the lower side is negatively adsorbed and fixed by the adsorption disk 701, so as to further improve the fixation degree of the glass and ensure the stability during the transportation of the glass.

[0066] After the glass is transported to the target position by this device, the operator controls the driving device and the lifting frame 402 to restore the supporting frame 403 and the sliding frame 404 to their original positions, and the supporting plate 705 loses the squeeze and returns to its original position, causing the uppermost suction plate 701 to lose its fixation to the uppermost glass, and the uppermost glass is removed. After the uppermost glass is removed, the two uppermost supporting plates 5 lose the squeeze, and the second uppermost frame 202 moves upward and returns to its original position under the action of adjacent springs. At the same time, the two uppermost supporting plates 5 drive the suction plates 701 thereon to move upward and lose their fixation to the lower glass, and this is repeated until all the glass is removed.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
