Description

Technical Field

[0001] The invention belongs to the technical field of panel transport and transfer, and in particular relates to a structure and a method for reducing the tilt amount of a slider guide rail lifting device. Background Art

[0002] At present, when using lifting and handling equipment to carry heavy objects, the telescopic pick-and-place device of the equipment is in a cantilever beam state when it is extended to pick up and place the heavy objects, and the cantilever distance is long. The heavy objects are heavy (tons), and the linear guide rails are subjected to a large eccentric load moment. This will generate an eccentric load moment on the linear guide rail under the action of gravity, causing the lifting and placing device to tilt beyond the industry specified range when picking and placing, affecting the safe operation of the equipment, and seriously causing damage to the transported goods. The telescopic pick-and-place device of the equipment is connected to the lifting frame assembly by bolts, and the lifting frame assembly is connected to the equipment walking frame through two pairs of symmetrically arranged single-slider linear guides on the left and right. Since there is a certain gap between the inner side of the slider and the side of the guide rail, and in the entire equipment, it is affected by many factors such as the rigidity of the structural parts, the rigidity of the slider itself, the material of the ball in the slider, and the reverse load of the slider preload, the calculation of the tilt of the device is relatively complicated. Through practical verification, it is known that the main reason for the excessive tilt is related to the gap between the slider and the guide rail, the material of the ball in the slider, and the gap between the block and the slide rail installation.

[0003] Therefore, a structure and method for reducing the inclination of the slider guide lifting device are needed to solve the problem in the prior art that the guide rail is subjected to a large eccentric load torque, causing the lifting and placing device to tilt beyond the industry prescribed range during picking and placing, affecting the safe operation of the equipment and even causing damage to the transported goods. Summary of the invention

[0004] The object of the present invention is to provide a structure for reducing the tilt of a slider guide rail lifting device to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solutions: In a first aspect, the present invention provides a structure for reducing the tilting amount of a slider guide lifting device, comprising a walking frame, wherein two racks are respectively arranged on opposite sides of the inner side wall of the walking frame; A lifting frame assembly is arranged in the middle of the walking frame, and four side panels are respectively fixed to two opposite side surfaces of the outer side wall of the lifting frame assembly; A limiting hole is provided on a side surface of the side plate, an inner ring is movably connected in the limiting hole, a fixed shaft is fixed between two inner rings, a gear is fixed on an outer side wall of the fixed shaft, and the gear is meshed with the rack; A rotating shaft, fixed to one end of the two fixed shafts close to each other; The sliding assembly is arranged between the walking frame and the lifting frame assembly.

[0006] Furthermore, the sliding assembly includes four guide rails, two of which are respectively fixed on both sides of one side of the inner wall of the walking frame, and the other two guide rails are respectively fixed on both sides of the other side of the inner wall of the walking frame. Two sliders are respectively fixed on the opposite sides of the outer wall of the lifting frame assembly, and the sliders are correspondingly and movably engaged on the guide rails.

[0007] Furthermore, two limiting grooves are respectively provided on two opposite side surfaces of the inner side wall of the walking frame, and racks are movably engaged in the limiting grooves.

[0008] Furthermore, two positioning blocks are fixed to two opposite side surfaces of the inner wall of the walking frame, the positioning blocks correspond to the rack, a bolt is threadedly connected to one side of the positioning block, and one side of the bolt is threadedly connected to one end of the rack.

[0009] Furthermore, the limiting groove is a rectangular groove.

[0010] Furthermore, the positioning block is a rectangular structure.

[0011] Furthermore, the rotating shaft is a cylindrical structure.

[0012] Furthermore, the inner ring is a circular ring structure.

[0013] Furthermore, the fixed shaft is a cylindrical structure.

[0014] In a second aspect, the present invention provides an operating method for reducing the tilt of a slider guide lifting device, comprising the following steps: S1, start the handling device, move the handling device to a position close to the heavy object, then start the telescopic pick-and-place device, move the storage box to the heavy object position, place the heavy object in the storage box, reset the telescopic pick-and-place device, and then operate the handling device to move to the corresponding position; S2, start the servo motor to rotate the screw rod, which drives the lifting frame assembly to rise, and then drives the heavy object to rise. After the heavy object is raised to a specified distance, the heavy object in the storage box is processed; S3. When the center of gravity of the heavy object placed on the storage box does not coincide with the center of gravity of the storage box and the lifting frame assembly as a whole, the slider on the side where the center of gravity of the heavy object is located moves downward, and the other side moves upward. At this time, the slider on the side where the center of gravity of the heavy object is located is affected by the gravity G and the force F of the guide rail on the slider when the slider is tilted. At this time, the force F of the guide rail on the slider can be limited and blocked by the meshing of the gear and the rack to prevent the force F from causing the slider to tilt.

[0017] (3) By setting bolts on the positioning block, the position of the rack can be adjusted to reduce the return clearance of the gear rack. When the gear rack is not worn very seriously, the vertical position of the rack can be adjusted by rotating the bolts to make it mesh closely with the gear again, thus saving the time of replacing the gear rack and further improving the stable operation time of the equipment.

[0023] A specific embodiment of the present invention, embodiment 1: Figure 1-Figure 11 As shown, a structure for reducing the tilt of a slider guide rail lifting device is disclosed, comprising a walking frame 100, wherein two racks 300 are respectively arranged on opposite sides of the inner side wall of the walking frame 100; The lifting frame assembly 200 is arranged in the middle of the walking frame 100, and four side panels 201 are fixed to two opposite side surfaces of the outer side wall of the lifting frame assembly 200; A limiting hole is provided on a side surface of the side plate 201, an inner ring 204 is movably connected in the limiting hole, a fixed shaft 202 is fixed between two inner rings 204, a gear 203 is fixed on the outer wall of the fixed shaft 202, and the gear 203 is meshed with the rack 300; The rotating shaft 205 is fixed to one end of the two fixed shafts 202 close to each other; The sliding assembly is disposed between the walking frame 100 and the lifting frame assembly 200 .

[0024] As a further solution of the present invention, the sliding assembly includes four guide rails 101, two of which are respectively fixed on both sides of one side of the inner wall of the walking frame 100, and the other two guide rails 101 are respectively fixed on both sides of the other side of the inner wall of the walking frame 100, and two sliders 102 are respectively fixed on the opposite sides of the outer wall of the lifting frame assembly 200, and the sliders 102 are correspondingly and movably engaged on the guide rails 101.

[0025] By setting the guide rail 101 and the slider 102, the lifting frame assembly 200 can be movably connected to the walking frame 100, wherein the guide rail 101 and the walking frame 100 are connected by bolts, and the slider 102 and the lifting frame assembly 200 are connected by bolts. The slider 102 and the guide rail 101 can be replaced according to the use requirements of different heavy objects to adapt to different usage scenarios.

[0026] This solution has the following working process: when carrying heavy objects, start the carrying equipment and move the carrying equipment to a position close to the heavy object. Then start the telescopic picking and placing device to move the storage box to the position of the heavy object. Place the heavy object in the storage box to reset the telescopic picking and placing device. Then, after operating the carrying equipment to move to the corresponding position, start the servo motor to rotate the screw rod. The screw rod drives the lifting frame assembly 200 to rise, and then drives the heavy object to rise. After the heavy object is raised a certain distance, the heavy object in the storage box can be processed.

[0027] When the center of gravity of the heavy object placed on the storage box does not coincide with the center of gravity of the storage box and the lifting frame assembly 200 as a whole, the slider 102 on the side where the center of gravity of the heavy object is located moves downward and the other side moves upward. At this time, the slider 102 on the side where the center of gravity of the heavy object is located is subjected to the gravity G and the force F exerted on the slider 102 by the guide rail 101 when the slider 102 is tilted. At this time, the force F exerted on the slider 102 by the guide rail 101 can be limited and blocked by the engagement of the gear 203 and the rack 300 to prevent the force F from causing the slider 102 to tilt.

[0028] According to the above working process, it can be known that by setting the gear 203 and the rack 300, the inclination of the guide rail 101 can be reduced when the telescopic pick-up and placement device picks up and places heavy objects, ensuring the normal pick-up and placement of goods. Compared with the slider 102 guide rail 101 and the lifting frame assembly 200 without the gear 203 rack 300 structure, the use of the gear 203 rack 300 previously affected the gap between the inner side of the slider 102 and the guide rail 101, the installation gap of the guide rail 101, etc., which caused the telescopic pick-up and placement device to produce a large inclination when telescopically picking up and placing heavy objects, resulting in the two sliders 102 not being at the same level, and the slider 102 close to the center of the heavy object being lower than the slider 102 far from the center of the heavy object. As the equipment runs longer, the slider 102 wears more, which may further increase the inclination of the lifting frame assembly 200, and may seriously cause the goods being transported to fall and be damaged. Adding two pairs of gears 203 and racks 300 beside the two parallel vertical guide rails 101 can effectively reduce the tilting amount of the telescopic pick-and-place device when it is extended, and prevent the lack of precision in heavy object handling due to excessive tilting, and prevent economic losses caused by damage to the transported goods due to excessive tilting. In addition, the added gears 203 and racks 300 also improve the carrying capacity of the equipment.

[0029] By replacing the worn gear 203 or rack 300 to extend its service life, the stable operation time of the equipment is effectively extended; in addition, by changing the center distance of the gear 203 and the rack 300 and reducing the meshing clearance of the gear 203 and the rack 300, the pick-and-place accuracy is increased, the inclination caused by the offset load is reduced, the normal pick-and-place of the equipment is ensured, and the safety of the equipment operation is improved.

[0030] By setting bolts on the positioning block, the position of the rack 300 can be adjusted to reduce the return clearance of the rack 300 of the gear 203. When the wear of the rack 300 of the gear 203 is not very serious, the vertical position of the rack 300 can be adjusted by rotating the bolts to make it mesh closely with the gear 203 again, thereby saving the time of replacing the gear 203 rack 300 and further improving the stable operation time of the equipment.

[0031] Among them, the upward or downward movement distance of the lifting frame assembly 200 is 300mm. Therefore, when the gap between the rack 300 and the gear 203 exceeds 0.15mm-0.4mm, the rack 300 can be moved down 0.2mm-0.3mm by rotating the bolt, so that the gear 203 is meshed with the non-worn position on the rack 300, so that the gear 203 and the rack 300 can achieve a tight meshing effect again.

[0032] As a further solution of the present invention, two limiting grooves 400 are respectively formed on two opposite side surfaces of the inner wall of the walking frame 100 , and a rack 300 is movably engaged in the limiting groove 400 .

[0033] By setting the limiting groove 400, the position of the rack 300 can be limited to prevent the rack 300 from moving left and right.

[0034] As a further solution of the present invention, two positioning blocks are fixed to the inner walls of the walking frame 100 on opposite sides, respectively, and the positioning blocks correspond to the rack 300. A bolt is threadedly connected to one side of the positioning block, and one side of the bolt is threadedly connected to one end of the rack 300.

[0035] The position of the rack 300 can be fixed by the provided positioning blocks and bolts, and the vertical position of the rack 300 can be adjusted by rotating the bolts to meet actual usage requirements.

[0036] As a further solution of the present invention, the limiting groove 400 is a rectangular groove.

[0037] By setting the limiting groove 400 structure as a rectangular groove, the rack 300 can be engaged in the limiting groove 400, so as to facilitate limiting the position of the rack 300.

[0038] As a further solution of the present invention, the positioning block is a rectangular structure.

[0039] The positioning block is provided so that the bolt can be easily connected to the rack 300 .

[0040] As a further solution of the present invention, the rotating shaft 205 is a cylindrical structure.

[0041] The gears 203 on both sides can be connected together by setting the rotating shaft 205. As a further solution of the present invention, the inner ring 204 is a circular ring structure.

[0042] The inner ring is provided to facilitate the rotation of the fixed shaft 202 .

[0043] As a further solution of the present invention, the fixed shaft 202 is a cylindrical structure.

[0044] The fixed shaft 202 is provided so that the gear 203 can rotate.

[0045] The lifting frame assembly 200 of the present invention is connected to the side of the handling equipment, a telescopic pick-up and placement device is fixed in the middle of the lifting frame assembly 200, and a storage box is fixed at the output end of the telescopic pick-up and placement device for storing heavy objects.

[0046] A threaded sleeve is fixed to the lifting frame assembly 200 near one side of the walking frame 100, and two fixed blocks are fixed to one side of the walking frame 100. A lead screw is movably connected between the two fixed blocks near one side of each other. A servo motor is fixed on the walking frame, and the output end of the servo motor is fixed to one end of the lead screw. The threaded sleeve is movably connected to the outer wall of the lead screw. The lead screw is driven to rotate by starting the motor to move the lifting frame assembly 200.

[0047] The lifting frame assembly 200 is used for transporting heavy objects, and the size of the gear 203 and the rack 300 can be flexibly designed according to the size of the different transported goods.

[0048] The gear 203 and the rack 300 can be flexibly selected according to the size of the lifting frame assembly 200, the size of the installation space, and the load-bearing capacity; The slider 102 and the guide rail 101 can be flexibly selected according to the movement stroke and load size of the lifting frame assembly 200; Among them, Figure 1 In order to simplify the model, only a partial structure of the lifting frame assembly 200 on one side is shown. The lifting frame assembly 200 and the walking frame 100 are both circular structures.

[0049] Working condition description when rack 300 is not added: Figure 7 Shown Taking the handling method of this equipment as an example, the process is explained. When the gear 203 and the rack 300 are not installed: the center distance between the two sliders 102 is 704mm. The actual measurement shows that the left slider 102 rises 2.5mm and the right slider 102 falls 2.5mm. Figure 7 The distance of 1450 mm between the reflector and the center of the two sliders 102 is shown in FIG. 1. Theoretically, when the telescopic device is in the cantilever state, the tilt is 12.80 mm, which is substantially consistent with the actually measured offset of 12.5 mm.

[0050] Working condition description when adding rack 300: as shown in the attached Figure 8 Shown Taking the handling method of this equipment as an example, the process is explained. When the gear 203 and the rack 300 are installed: the center distance between the two sliders 102 is still 704mm. The actual measurement shows that the left slider 102 rises 0.5mm and the right slider 102 falls 0.5mm. Figure 8 The distance of 1450 mm between the reflector and the center of the two sliders 102 is shown in FIG. 1. Theoretically, when the telescopic device is in the cantilever state, the tilt is 2.58 mm, which is substantially consistent with the actually measured offset of 2.5 mm.

[0051] Therefore, it can be seen that when the rack 300 is installed, the tilt is reduced from 12.80mm to 2.58mm, a reduction of about 80%. Therefore, the design of the gear 203 rack 300 structure can solve the problem of excessive tilt when the single slider 102 guide rail 101 is used vertically. At the same time, according to different installation space sizes and different slider 102 guide rail 101 layout structures, we can match different numbers and layouts of gears 203 racks 300 to reduce the excessive displacement of the slider 102 after being stressed in different engineering applications.

[0052] According to the working conditions, the selection of gear 203 rack 300 is calculated: the spacing of the rack 300 on the same side is 404mm, the left and right spacing is 1906mm, the load is 600kg and the load eccentricity is 1300mm.

[0053] 1. Since the space couple can be moved in parallel, when it moves from one plane to another parallel plane of the rigid body, it does not affect its effect on the rigid body; therefore, according to the principle of equilibrium of the plane couple system: the algebraic sum of the moments of the couples in the couple system is zero, that is, ; Substituting the above formula into the data: Assume that the torque generated on the gear 203 rack 300 is M2=F2x0.404 and the torque generated by the eccentric weight is M1=600x9.8x13. 2F2x0.404=600x9.8x1.3, and F2=9460.4N, that is, the normal force acting on a single tooth surface is 9460.4N, that is, Fn=9460.4N. (at the pitch circle) 2. For this lifting and handling equipment, the gear 203 rack 300 is mainly subjected to the eccentric load of heavy objects during handling. Therefore, according to the physical meaning of the gear 203 module and the Misumi gear 203 selection manual, the module m=3 and the number of teeth z=40 can be initially selected. From the Misumi gear 203 selection table, it is known that the gear 203 with m=3, z=40, b (tooth width)=30 can withstand an allowable transmission force bending strength of 420.10Nm. Then, according to the maximum tolerable bending moment of the selected gear 203, it is verified whether the actual load borne by the gear 203 rack 300 on this equipment exceeds the maximum tolerable bending moment of the selected gear 203 rack 300. The calculation process is as follows: 1) Determine the actual maximum bending moment that the gear 203 rack 300 can withstand. According to the Misumi standard gear 203 selection manual, the gear 203 with m=3, z=40, b (tooth width)=30 can withstand a maximum bending strength moment of 420.10Nm. However, in the actual design, in order to further increase the bending strength of the gear 203, the tooth width b is designed to be 60, and the bending strength can be increased by 50% (influenced by factors such as tooth direction error), and the actual maximum bending moment that the gear 203 can withstand is: Ti=420.10x(1+50%)=630.15Nm 2) From 1., we know that the normal force acting on a single tooth surface is Fn=9460.4N, and m=3, z=40, the pitch circle pressure angle is the standard a=20°, the pitch circle size is d=120mm, the radius r=60mm, then the actual bending moment of gear 203 is ; Substituting the data, we get: ; Through the above calculation, it is known that the actual bending moment 533.39 Nm borne by the gear 203 is less than the maximum bending moment 630.15 Nm that the gear 203 rack 300 can withstand.

[0054] In summary, the design of the gear 203 and the rack 300 meets the design requirements.

[0055] Embodiment 2: A method for reducing the tilt of a slider guide lifting device is proposed, comprising the following steps: S1, start the handling device, move the handling device to a position close to the heavy object, then start the telescopic pick-and-place device, move the storage box to the heavy object position, place the heavy object in the storage box, reset the telescopic pick-and-place device, and then operate the handling device to move to the corresponding position; S2, start the servo motor to rotate the screw rod, which drives the lifting frame assembly 200 to rise, and then drives the heavy object to rise. After the heavy object is raised to a specified distance, the heavy object in the storage box is processed; S3. When the center of gravity of the heavy object placed on the storage box does not coincide with the center of gravity of the storage box and the lifting frame assembly 200 as a whole, the slider 102 on the side where the center of gravity of the heavy object is located moves downward and the other side moves upward. At this time, the slider 102 on the side where the center of gravity of the heavy object is located is affected by the gravity G and the force F exerted on the slider 102 by the guide rail 101 when the slider 102 is tilted. At this time, the force F exerted on the slider 102 by the guide rail 101 can be limited and blocked by the engagement of the gear 203 and the rack 300 to prevent the force F from causing the slider 102 to tilt.

[0056] Principle: When carrying heavy objects, start the carrying equipment and move it to a position close to the heavy objects. Then start the telescopic pick-and-place device to move the storage box to the position of the heavy objects. Place the heavy objects in the storage box to reset the telescopic pick-and-place device. Then, operate the carrying equipment to move to the corresponding position and start the servo motor to rotate the screw rod. The screw rod drives the lifting frame assembly 200 to rise, and then drives the heavy objects to rise. After the heavy objects are lifted a certain distance, the heavy objects in the storage box can be processed.

[0057] When the center of gravity of the heavy object placed on the storage box does not coincide with the center of gravity of the storage box and the lifting frame assembly 200 as a whole, the slider 102 on the side where the center of gravity of the heavy object is located moves downward and the other side moves upward. At this time, the slider 102 on the side where the center of gravity of the heavy object is located is subjected to the gravity G and the force F exerted on the slider 102 by the guide rail 101 when the slider 102 is tilted. At this time, the force F exerted on the slider 102 by the guide rail 101 can be limited and blocked by the engagement of the gear 203 and the rack 300 to prevent the force F from causing the slider 102 to tilt.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

8. A structure for reducing the tilt of a slider guide rail lifting device according to claim 7, characterized in that: The inner ring (204) is a circular ring structure.

9. A structure for reducing the tilt of a slider guide rail lifting device according to claim 8, characterized in that: The fixed shaft (202) is a cylindrical structure.

10. An operating method for reducing the tilt of a slider guide lifting device, characterized in that: The following steps are involved: S1, start the handling device, move the handling device to a position close to the heavy object, then start the telescopic pick-and-place device, move the storage box to the heavy object position, place the heavy object in the storage box, reset the telescopic pick-and-place device, and then operate the handling device to move to the corresponding position; S2, starting the servo motor to rotate the screw rod, which drives the lifting frame assembly (200) to rise, thereby driving the heavy object to rise, and after the heavy object is raised to a specified distance, the heavy object in the storage box is processed; S3. When the center of gravity of the heavy object placed on the storage box does not coincide with the center of gravity of the storage box and the lifting frame assembly (200) as a whole, the slider (102) on the side where the center of gravity of the heavy object is located moves downward, and the other side moves upward. At this time, the slider (102) on the side where the center of gravity of the heavy object is located is subjected to the gravity G and the force F exerted on the slider (102) by the guide rail (101) when the slider (102) is tilted. At this time, the force F exerted on the slider (102) by the guide rail (101) can be limited and blocked by the meshing of the gear (203) and the rack (300), thereby preventing the force F from causing the slider (102) to tilt.
