Description

Technical Field

[0001] This application relates to the field of wooden pallet manufacturing technology, and in particular to a positioning fixture for wooden pallet assembly. Background Technology

[0002] Pallets are often an indispensable piece of equipment in the transportation of goods. During loading and unloading, goods are stacked on pallets, and forklifts are used to insert into the bottom of the pallets to transport the goods along with the pallets. Wooden pallets, due to their high structural strength, are a widely used technology in the transportation packaging industry. Wooden pallets are generally composed of multiple parallel bottom straps and a panel. During the manufacturing process of wooden pallets, the panel needs to be attached to the multiple bottom straps. Therefore, the stability of the positional relationship between each bottom strap and the panel has an important impact on the attachment effect. This application proposes a positioning fixture for attaching wooden pallets, which is suitable for fixing the position of the bottom straps and the panel of the wooden pallet during the attachment process. Summary of the Invention

[0003] In view of this, this application proposes a positioning fixture for wooden pallet ordering.

[0004] According to one aspect of this application, a positioning fixture for attaching wooden pallets is provided, characterized in that it includes: an mounting frame, a movable crossbeam, two first positioning devices and two or more second positioning devices; The movable crossbeam is movably installed inside the mounting frame and can move along the width of the mounting frame. Multiple bottom straps and panels suitable for placing wooden pallets are located between the mounting frame and the movable crossbeam. The two first positioning devices are respectively fixedly installed on the side walls of the moving crossbeam and the mounting frame facing each other. Two or more second positioning devices are movably mounted on the side walls of the moving beam and the mounting frame facing each other via a deceleration and moving mechanism. The movement direction of the two or more second positioning devices is parallel to the length direction of the moving beam so that the deceleration and moving mechanism drives the second positioning devices to move in the X-axis direction. The movable crossbeam is suitable for moving the first and second positioning devices on the movable crossbeam in the Y-axis direction so as to clamp the multiple bottom straps of the wooden pallet together with the first and second positioning devices on the mounting frame. Each of the first and second positioning devices includes: a lifting platform, a telescopic component, a gripper, and a fixed platform. The lifting platform is movably mounted on the fixed platform, the telescopic component is movably mounted on the top of the lifting platform, and the gripper is movably mounted on the top of the telescopic component. The movement directions of the telescopic component and the gripper are parallel to the movement direction of the moving crossbeam. The lifting platform is suitable for driving the gripper to move in the Z-axis direction to press or release the panel of the wooden pallet.

[0005] Beneficial effects: The mounting frame provides rigid support for the first positioning device, the second positioning device, and the moving crossbeam, integrating all core components; the moving crossbeam can move inside the mounting frame to simultaneously drive all the first and second positioning devices on the moving crossbeam to move in the Y-axis direction, so that the first positioning devices on the moving crossbeam can move in a direction away from or towards the first positioning device on the mounting frame; the two first positioning devices contact the two ends of the outermost bottom strip to clamp the bottom strip and keep it in its current position; the remaining bottom strips are clamped and fixed by the second positioning devices on the moving crossbeam and the second positioning devices on the mounting frame, and the distance between two adjacent second positioning devices can be adjusted to adapt to the distance between two adjacent bottom strips; the second positioning devices on the moving crossbeam are one-to-one with the upper second positioning devices on the mounting frame, ensuring that one second positioning device on the moving crossbeam and the upper second positioning device on the mounting frame jointly press against the two ends of the same bottom strip. The lifting platform can move the grippers up and down in the Z-axis direction, thereby pressing down on the panel of the wooden pallet to make the panel firmly contact the bottom belt. The simultaneous pressing action of multiple grippers can ensure the positional stability of the panel.

[0015] Figure 1 This diagram shows the main structure of a positioning fixture for attaching wooden pallets, according to an embodiment of this application. Figure 1As shown, this positioning fixture for wooden pallet assembly includes: a mounting frame 100, a movable crossbeam 200, two first positioning devices 300, and two or more second positioning devices 400; the movable crossbeam 200 is movably disposed inside the mounting frame 100 and can move along the width direction of the mounting frame 100; multiple bottom straps 910 and panels 900 for placing wooden pallets are located between the mounting frame 100 and the movable crossbeam 200; the two first positioning devices 300 are respectively fixedly installed on the side walls of the movable crossbeam 200 and the mounting frame 100 facing each other; the two or more second positioning devices 400... The 0 are respectively movably mounted on the side walls of the moving beam 200 and the mounting frame 100 facing each other via a deceleration moving mechanism, and the moving direction of two or more second positioning devices 400 is parallel to the length direction of the moving beam 200 so that the deceleration moving mechanism drives the second positioning devices 400 to move in the X-axis direction; the moving beam 200 is suitable for driving the first positioning device 300 and the second positioning device 400 on the moving beam 200 to move in the Y-axis direction so as to jointly clamp the multiple bottom straps 910 of the wooden pallet together with the first positioning device 300 and the second positioning device 400 on the mounting frame 100. Each of the first positioning device 300 and the second positioning device 400 includes: a lifting platform 320, a telescopic member 380, a gripper 370, and a fixed platform 310. The telescopic member 380 is movably disposed on the top of the lifting platform 320, and the gripper 370 is movably disposed on the top of the telescopic member 380. The movement directions of the telescopic member 380 and the gripper 370 are parallel to the movement direction of the moving crossbeam 200. The lifting platform 320 is suitable for driving the gripper 370 to move in the Z-axis direction to press or release the panel 900 of the wooden pallet.

[0016] Here, it should be noted that, as Figure 17As shown, the mounting frame 100 is suitable for providing rigid support for the first positioning device 300, the second positioning device 400, and the moving crossbeam 200, integrating all core components. The moving crossbeam 200 can move inside the mounting frame 100 to drive all the first positioning devices 300 and second positioning devices 400 on the moving crossbeam 200 to move simultaneously in the Y-axis direction, so that the first positioning devices 300 on the moving crossbeam 200 can move in a direction away from or towards the first positioning devices 300 on the mounting frame 100, so that the two first positioning devices 300 contact the two ends of the outermost bottom strip 910 to clamp the bottom strip 910 and keep it in its current position; the remaining bottom strips 910 are clamped and fixed by the second positioning devices 400 on the moving crossbeam 200 and the second positioning devices 400 on the mounting frame 100. Since the second positioning devices 400 on the moving crossbeam 200 can move along the length of the moving crossbeam 200... The upper second positioning device 400 of the mounting frame 100 can move along the length of the mounting frame 100 in the X-axis direction to move on the moving crossbeam 200. This allows adjustment of the distance between two adjacent second positioning devices 400 to match the distance between two adjacent bottom straps 910. If the distance between two adjacent bottom straps 910 is large, the distance between the first positioning device 300 and multiple second positioning devices 400 can be increased. If the distance between two adjacent bottom straps 910 is small, the distance between the first positioning device 300 and multiple second positioning devices 400 can be decreased. This ensures that the second positioning devices 400 on the moving crossbeam 200 and the upper second positioning devices 400 on the mounting frame 100 are aligned one-to-one, ensuring that one second positioning device 400 on the moving crossbeam 200 and the previous second positioning device 400 on the mounting frame 100 together press against both ends of the same bottom strap 910. Furthermore, each of the first positioning devices 300 and the second positioning device 400 has the same structure. Its lifting platform 320 can drive the grippers 370 to move up and down in the Z-axis direction, thereby causing the grippers 370 to press down on the panel 900 of the wooden pallet, ensuring that the panel 900 firmly contacts the bottom strap 910. The simultaneous pressing action of multiple grippers 370 ensures the positional stability of the panel 900. This application can clamp multiple bottom straps 910 of the wooden pallet during the pallet assembly process, pressing down on the panel 900 to maintain a stable relative positional relationship between the various structural components. This avoids external forces changing the position of the structural components during assembly, improving assembly efficiency while ensuring that the assembled wooden pallet meets specifications.

[0017] In one possible implementation, the main body of the mounting frame 100 is a rectangular frame structure, and mounting plates 110 are provided at the two top corners for mounting the first drive motor 720; the main body of the movable crossbeam 200 is a rod-shaped structure, and the movable crossbeam 200 is placed horizontally inside the mounting frame 100 and perpendicularly connected to both sides of the width of the mounting frame 100.

[0018] In one possible implementation, a beam drive mechanism is also included; both ends of the movable beam 200 are movably connected to the mounting frame 100 via the beam drive mechanism. The beam drive mechanism is suitable for realizing the automatic movement of the movable beam 200. Further, as... Figure 2 and Figure 3 As shown, the crossbeam drive mechanism includes: a first drive motor 720, a first lead screw 700, a first lead screw nut 730, and a crossbeam mounting plate 760. The first drive motor 720 is mounted on the mounting plate 110 at the top corner of the mounting frame 100. The first lead screw 700 is mounted on the outer wall of the mounting frame 100. The output shaft of the first drive motor 720 is connected to the first lead screw 700. The first lead screw nut 730 is sleeved on the first lead screw 700 and connected to the crossbeam mounting plate 760. The crossbeam mounting plate 760 is connected to the end of the movable crossbeam 200 so that when the first drive motor 720 drives the first lead screw 700 to rotate, the first lead screw nut 730 drives the movable crossbeam 200 to move. The two ends of the first lead screw 700 are connected to the outer wall of the mounting frame 100 through first mounting seats 710. The first mounting seats 710 are mounted on the outer wall of the mounting frame 100 by screws. The first lead screw 700 passes through one first mounting seat 710 and abuts against the other first mounting seat 710. The first lead screw nut 730 is sleeved on the first lead screw 700 and threadedly connected to the first lead screw 700. Therefore, when the first drive motor 720 drives the first lead screw 700 to rotate, the first lead screw nut 730 will move along the length of the first lead screw 700. The first connecting plate 740 is fixedly sleeved on the outside of the first lead screw nut 730. The crossbeam mounting plate 760 is fixedly mounted on the end face of the moving crossbeam 200. The side wall of the crossbeam mounting plate 760 is connected to the first connecting plate 740 through the second connecting plate 750. Therefore, when the first lead screw nut 730 makes a linear displacement, it will drive the moving crossbeam 200 to move through the first connecting plate 740, the second connecting plate 750, and the crossbeam mounting plate 760.

[0019] Preferably, the first drive motor 720 is a lead screw stepper motor, which has its own first lead screw 700.

[0020] Furthermore, such as Figure 3 As shown, a first slider 770 is provided on the side of the crossbeam mounting plate 760 away from the moving crossbeam 200. A first slide rail 780 is provided on the inner sidewalls on both sides of the width of the mounting frame 100. The first slide rail 780 is embedded in the through groove of the first slider 770. The first slider 770 can move on the first slide rail 780, thereby improving the moving stability of the moving crossbeam 200.

[0021] In one possible implementation, such as Figure 9As shown, it also includes two second lead screws 800; the two second lead screws 800 are respectively disposed on the side of the moving crossbeam 200 and the mounting frame 100 facing each other, and two or more second positioning devices 400 are respectively connected to the two second lead screws 800 through a deceleration moving mechanism. Further, both ends of the two second lead screws 800 are connected to the moving crossbeam 200 or the mounting frame 100 through a second mounting base 810. The second mounting base 810 is fixed to the moving crossbeam 200 or the mounting frame 100 by screws. A square hole is opened on the inner side of the second mounting base 810. A square block 801 protrudes from both ends of the two second lead screws 800. The square block 801 is inserted into the square hole to achieve stable installation of the two second lead screws 800 and ensure that the second lead screws 800 are not rotated by the second lead screw nut 851.

[0022] In one possible implementation, such as Figure 4 As shown, each of the first positioning device 300 and the second positioning device 400 includes: a lifting platform 320, a telescopic member 380, a gripper 370, and a fixed platform 310. The lifting platform 320 is movably mounted on the fixed platform 310, the telescopic member 380 is movably mounted on the top of the lifting platform 320, and the gripper 370 is movably mounted on the top of the telescopic member 380. It should be noted that the fixed platform 310 of the first positioning device 300 is directly connected to the moving crossbeam 200 or the mounting frame 100, and the fixed platform 310 of the second positioning device 400 is connected to the deceleration and movement mechanism. The lifting platform 320 is used to adjust the height of the gripper 370, and the telescopic member 380 is used to adjust the extension range of the gripper 370 to improve adaptability and facilitate the pressing of panels 900 of different thicknesses and sizes.

[0023] Furthermore, the fixing platform 310 includes a first fixing plate 311 and a second fixing plate 312 arranged perpendicularly to each other, wherein the first fixing plate 311 is arranged horizontally, as shown below. Figure 5 As shown, a through hole 3111 is provided in the middle for the lifting drive device 330 to pass through, and screw holes 3112 for connecting the drive device 330 are provided around the perimeter; the second fixing plate 312 is vertically arranged on one side of the first fixing plate 311, and the side of the second fixing plate 312 opposite to the first fixing plate 311 has screw holes for connecting the moving crossbeam 200, the mounting frame 100, or the deceleration moving mechanism, such as... Figure 4 As shown, the second fixing plate 312 has two second slide rails 360 perpendicular to the first fixing plate 311 on one side facing the second fixing plate 312.

[0024] like Figure 4As shown, the lifting platform 320 includes: a first lifting plate 325, a second lifting plate 322, a third lifting plate 323, a fourth lifting plate 324, and a fifth lifting plate 321; the first lifting plate 325 is horizontally arranged, with a through hole in the middle for the lifting drive device 330 to pass through, and screw holes around the through hole for connecting the third lead screw nut 340; the second lifting plate 322 is vertically arranged on the side of the first lifting plate 325 away from the second fixed plate 312, and the third lifting plate 323 is horizontally arranged on the second lifting plate 322. The top surface of the first lifting plate 325 is parallel to the top surface of the second fixed plate 312. The fourth lifting plate 324 is vertically arranged on the top surface of the third lifting plate 323 and is suitable for installing the telescopic component drive device 381. The fifth lifting plate 321 is arranged on the top surface of the first lifting plate 325 and is parallel to the second lifting plate 322. The fifth lifting plate 321 has two second sliders 350 on the side away from the second lifting plate 322. The two second slide rails 360 are respectively embedded in the through grooves of the two second sliders 350, and the second sliders 350 can move on the second slide rails 360.

[0025] In one possible implementation, the lifting drive device 330 adopts a lead screw stepper motor and further includes: a third lead screw nut 340, which is disposed on the top surface of the first lifting plate 325 and fixedly connected to the first lifting plate 325. The lifting drive device 330 is fixedly disposed on the bottom of the first fixed plate 311. The lead screw 331 of the lifting drive device 330 passes through the through hole 3111 of the first fixed plate 311 and the through hole of the first lifting plate 325. The third lead screw nut 340 is sleeved on the lead screw 331 of the lifting drive device 330 and threadedly connected to the lead screw 331. When the lead screw 331 of the lifting drive device 330 rotates, under the limiting action of the second slider 350 and the second slide rail 360, the third lead screw nut 340 moves up and down along the lead screw 331 of the lifting drive device 330 and drives the entire lifting platform 320 to move up and down.

[0026] In one possible implementation, it further includes: a telescopic component drive device 381, a third slider 383, and a third slide rail 384; such as Figure 6 As shown, the drive end of the telescopic component drive device 381 is connected to the telescopic component 380 to drive the telescopic component 380 to move. The third slider 383 is fixedly installed on the top surface of the third lifting plate 323 of the lifting platform 320. The third slide rail 384 is installed on the bottom surface of the telescopic component 380. The third slide rail 384 is embedded in the through groove of the third slider 383 and can move within the third slider 383.

[0027] Furthermore, such as Figure 7As shown, the main body of the telescopic component 380 is a rectangular block structure. The top of the telescopic component 380 is provided with a slider groove 385 for installing the fourth slider 374, and the bottom of the telescopic component 380 is provided with a slide rail groove 387 for installing the third slide rail 384. The end face of the telescopic component 380 is provided with a through hole 386 for the telescopic component driving device 381 to pass through, and the same end face is also provided with a screw hole 388 for connecting the telescopic plate 390.

[0028] In one possible implementation, the telescopic component drive device 381 employs a lead screw stepper motor, such as... Figure 6 As shown, the telescopic drive device 381 is fixedly mounted on the side wall of the fifth lifting plate 321, and the fourth lead screw nut 382 is mounted on the telescopic plate 390. A through hole 386 for the lead screw to pass through is provided on the axis of the telescopic component 380. The lead screw of the telescopic drive device 381 passes through the telescopic plate 390 and into the through hole 386 of the telescopic component 380. The fourth lead screw nut 382 is sleeved on the lead screw of the telescopic drive device 381 and is threadedly connected to the lead screw. At the same time, the fourth lead screw nut 382 is fixedly connected to the telescopic plate 390. Therefore, when the lead screw of the telescopic drive device 381 rotates, under the limiting action of the third slider 383 and the third slide rail 384, the fourth lead screw nut 382 moves along the lead screw of the telescopic drive device 381 and drives the telescopic component 380 and the gripper 370 to move in a telescopic manner.

[0029] In one possible implementation, it further includes: a gripper drive device 371, a fourth slider 374, and a fourth slide rail 373; such as Figure 5 As shown, the driving end of the gripper drive device 371 is connected to the gripper 370 to drive the gripper 370 to move. The fourth slider 374 is fixedly installed on the top surface of the telescopic member 380. The fourth slide rail 373 is installed on the bottom surface of the gripper 370. The fourth slide rail 373 is embedded in the through groove of the fourth slider 374 and can move within the fourth slider 374.

[0030] Furthermore, such as Figure 8 As shown, the main body of the gripper 370 is a rectangular block structure. The bottom of the gripper 370 is provided with a slide rail groove 376 suitable for installing the fourth slide rail 373. The gripper 370 is provided with a through hole 377 for the gripper drive device 371 to pass through. The same end face is also provided with a screw hole 378 suitable for connecting the telescopic plate 390.

[0031] In one possible implementation, the bottom surface of the end of the gripper 370 is provided with a pressure block 372, which is suitable for pressing down on the panel 900 of the wooden pallet. Preferably, the pressure block 372 is made of a soft material such as rubber.

[0032] In one possible implementation, such as Figure 4 and Figure 5As shown, the gripper drive device 371 adopts a lead screw stepper motor. The gripper drive device 371 is fixedly mounted on the side wall of the telescopic plate 390. The fifth lead screw nut 375 is fixedly mounted on the end face of the gripper 370. A through hole 377 for the lead screw to pass through is also provided on the axis of the gripper 370. The lead screw of the gripper drive device 371 passes through the telescopic plate 390 and enters the through hole 377 of the gripper 370. The fifth lead screw nut 375 is sleeved on the lead screw of the gripper drive device 371 and is threadedly connected to the lead screw. When the lead screw of the gripper drive device 371 rotates, under the limiting action of the fourth slider 374 and the fourth slide rail 373, the fifth lead screw nut 375 moves along the lead screw of the gripper drive device 371 and drives the gripper 370 to move in a telescopic manner.

[0033] Furthermore, both the gripper drive device 371 and the telescopic component drive device 381 adopt a lead screw stepper motor.

[0034] In one possible implementation, such as Figure 11 As shown, the deceleration and movement mechanism includes: a mounting frame 850, a second drive motor 860, a deceleration assembly, and a second lead screw nut 851; the second drive motor 860 and the fixed platform 310 are respectively arranged on opposite sides of the mounting frame 850, and the second drive motor 860 is connected to the second lead screw nut 851 through the deceleration assembly to drive the second lead screw nut 851 to rotate, the second lead screw nut 851 is sleeved on the second lead screw 800 and the second lead screw nut 851 is connected to the mounting frame 850.

[0035] Further such as Figure 11 As shown, the mounting bracket 850 has a "Π" shaped cross-section. The reduction gear assembly is located inside the "Π" shaped structure. The second drive motor 860 is mounted on the outer wall of the mounting bracket 850, and the output shaft of the second drive motor 860 passes through the mounting bracket 850 and extends into the inner side of the mounting bracket 850. Figure 13 As shown, the second fixing plate 312 of the fixing platform 310 is fixedly connected to one side of the third fixing plate 840, and one end of the third fixing plate 840 is fixedly connected to the side wall of the mounting bracket 850. The connection between the mounting bracket 850 and the fixing platform 310 is achieved through the connecting action of the third fixing plate 840. Figure 12 As shown, a connecting ring 852 is provided at the bottom of the side where the mounting bracket 850 is connected to the third fixing plate 840. The connecting ring 852 is sleeved on the second lead screw nut 851. When the second lead screw nut 851 moves linearly on the second lead screw 800, it synchronously drives the mounting bracket 850, the second drive motor 860, the third fixing plate 840, and the fixing platform 310 to move.

[0036] In one possible implementation, such as Figure 12As shown, a bearing 853 is provided between the connecting ring 852 of the mounting bracket 850 and the second lead screw nut 851 to provide lubrication and anti-wear function, and to prevent the mounting bracket 510 from rotating.

[0037] In one possible implementation, such as Figure 11 As shown, the reduction gear assembly includes: a small synchronous pulley 870, a large synchronous pulley 880, and a belt 890. The small synchronous pulley 870 is located inside the mounting bracket 850. The output shaft of the second drive motor 860 passes through the mounting bracket 850 and is inserted into the flat slot in the center of the small synchronous pulley 870. The small synchronous pulley 870 is connected to the large synchronous pulley 880 via the belt 890. The large synchronous pulley 880 is fitted with a second lead screw nut 851 and is fixedly connected to it. Under the transmission action of the reduction gear assembly, the second lead screw nut 851 is rotated at reduced speed.

[0038] In one possible implementation, such as Figure 9 and Figure 13 As shown, each third fixing plate 840 has a fifth slider 830 on the side opposite to the second fixing plate 312. Two fifth slide rails 820 are respectively fixedly installed on the sides of the moving beam 200 and the mounting frame 100 facing each other. The length direction of the fifth slide rail 820 is parallel to the length direction of the moving beam 200. The fifth slide rail 820 is embedded in the through groove of the fifth slider 830, and the fifth slider 830 can move on the fifth slide rail 820. Under the limiting action of the fifth slider 830 and the fifth slide rail 820, the translational stability of all second positioning devices 400 can be improved.

[0039] In one possible implementation, the two second positioning devices 400 located at the ends are further provided with limiting plates 500. The limiting plates 500 are movably connected to the base plate 540 via a pushing mechanism. The base plate 540 is disposed on the side wall of the fixed platform 310. The limiting plates 500 are suitable for limiting the position of the outermost bottom strip 910. Figure 14 As shown, the driving mechanism includes: a base plate 540, a folding plate 530, a gear drive motor 550, a gear 510, and a rack 520; the main body of the base plate 540 has a rectangular plate structure, and the base plate 540 is fixedly connected to the first fixed plate 311 of the fixed platform 310, as shown. Figure 15As shown, one side of the folding plate 530 is fixedly connected to the back of the base plate 540. The gear drive motor 550 is located on the side of the folding plate 530 away from the base plate 540. The drive end of the gear drive motor 550 passes through the folding plate 530 and is connected to the gear 510 to drive the gear 510 to rotate. One end of each of the two racks 520 passes through the other side of the folding plate 530 and extends into the through hole on the side wall of the base plate 540. The other ends of the two racks 520 are fixedly connected to the limiting plate 500. One of the racks 520 is meshed with the gear 510 so that the rack 520 can be moved when the gear 510 rotates. The rack 520 drives the limiting plate 500 at its end to move.

[0040] Furthermore, such as Figure 15 As shown, two fixing rings 560 are fixedly provided on the side of the folding plate 530 facing the limiting plate 500, and the rack 520 passes through the two fixing rings 560 respectively to achieve a stable installation of the rack 520.

[0041] like Figure 14 As shown, the base plate 540 has a circular clearance hole 531, and the gear is located inside the clearance hole 531.

[0042] In one possible implementation, such as Figure 1 As shown, it also includes a third positioning device 600, which is located on adjacent sides of the mounting frame 100 to contact the sidewall of the outermost bottom strip 910, along with the first positioning device 300. The third positioning device 600, the second positioning device 400, and the first positioning device 300 have the same structure and are all connected to the mounting frame 100 or the moving crossbeam 200 via a fixed platform 310; as shown... Figure 16 As shown, the fixing platform 310 of the third positioning device 600 is fixedly installed on one side of the width of the mounting frame 100 and close to the two first positioning devices 300.

[0043] It should be noted that, since the second positioning device 400 has a deceleration mechanism on the side facing the mounting frame 100 or the moving crossbeam 200, while the third positioning device 600 and the two first positioning devices 300 do not have deceleration mechanisms and are directly connected to the mounting frame 100 or the moving crossbeam 200, in order for the third positioning device 600 and the two first positioning devices 300 to be at the same height as the second positioning device 400, such as Figure 18 As shown, a pad 930 can be provided between the two first positioning devices 300, the third positioning device 600 and their respective connected mounting frames 100 or movable crossbeams 200.

[0044] like Figure 17As shown, this is a schematic diagram of the operation of this application. The lifting platforms 320 of the two first positioning devices 300 and the third positioning device 600 respectively contact the three side walls of the outermost bottom strip 910, and simultaneously clamp the outermost bottom strip 910 to ensure its positional stability. The lifting platform 320 of the second positioning device 400 contacts the two ends of the other bottom strips 910. The grippers 380 of the third positioning device 600, all the second positioning devices 400 and the two first positioning devices 300 are pressed against the top surface of the panel 900.
