[0002] Some longer workpieces (such as guide rails, steel pipes, and aluminum materials) may exhibit localized bending deformation, requiring straightening to meet usage requirements. To ensure these workpieces meet requirements, they are typically inspected first. Based on the inspection results, workpieces requiring straightening are sent for further processing, allowing defective workpieces to be used. To ensure the straightened workpieces are usable, they undergo another inspection. In practice, these longer workpieces are usually heavy and unsuitable for manual transport. Furthermore, they require multiple inspections, especially when there are many workpieces, as visually observing the degree of deformation to determine compliance with usage requirements is inconvenient.

[0023] Please refer to Figures 1 to 8 One embodiment of this utility model provides a straightening device that can be used for the detection and straightening of some long workpieces. For example, the workpiece to be detected and straightened can be a guide rail, a steel pipe, or an aluminum material.

[0024] In this embodiment, the orthopedic device includes: a first hoisting truss 11, a second hoisting truss 12, a first conveyor line L1, a second conveyor line L2, a third conveyor line L3, an oil removal device 20, a roller straightening device 30, and a visual inspection device 40.

[0025] The first hoisting truss 11 and the second hoisting truss 12 are arranged sequentially and at intervals along the first direction F1. The first and second hoisting trusses 11 and 12 are used to hoist the workpiece G. Specifically, each hoisting truss may include multiple material-grabbing units on both sides, arranged along the first direction F1 to accommodate the relatively long shape of the workpiece G. The material-grabbing units can grip the workpiece G under the drive of the lifting mechanism. Preferably, the material-grabbing units can be suction cups, grippers, or electromagnets. The first and second hoisting trusses 11 and 12 can also drive the workpiece G to translate, and the direction of translation when the workpiece G is hoisted is the second direction F2.

[0026] For reference Figure 4 and Figure 5 Along the second direction F2, the first conveyor line L1, the second conveyor line L2, and the third conveyor line L3 are arranged sequentially to transport the workpiece G between the first hoisting gantry 11 and the second hoisting gantry 12. Preferably, the first conveyor line L1, the second conveyor line L2, and the third conveyor line L3 are flow lines.

[0027] Preferably, a loading station is provided on the side of the first conveyor line L1 below the first hoisting truss 11 away from the second conveyor line L2. A material rack or material cart can be set here. The first hoisting truss 11 can hoist the workpiece G on the loading station to the first conveyor line L1.

[0028] For reference Figures 1-3 The degreasing device 20 and the roller straightening device 30 are located between the first hoisting truss 11 and the second hoisting truss 12. The degreasing device 20 can be set in the middle of the first conveyor line L1. The degreasing device 20 is equipped with an air knife. The workpiece G can be transported back and forth on the first conveyor line L1 and pass through the degreasing device 20 for degreasing. The degreasing process can prevent the oil stains attached to the workpiece G from coming into contact with other devices and causing pollution, so as to avoid affecting the straightening effect of the workpiece G.

[0029] For reference Figure 4 and Figure 5Multiple visual inspection devices 40 can be arranged along the first direction F1, and the visual inspection devices 40 can move back and forth to perform a more comprehensive inspection of the workpiece G. An inspection station P1 is provided between the second conveyor line L2 and the third conveyor line L3. The inspection station P1 is preferably located below the first hoisting truss 11. After the workpiece G has been degreased, it can be transferred to the inspection station P1. The multiple visual inspection devices 40 can inspect the workpiece G on the inspection station P1. The inspected workpiece G can be transferred to the third conveyor line L3. The third conveyor line L3 can transport the workpiece G from below the first hoisting truss 11 to below the second hoisting truss 12.

[0030] Preferably, a material unloading station is provided on the side of the first conveyor line L1 below the second hoisting truss 12 away from the second conveyor line L2. A material rack or material cart can be set here for unloading workpiece G.

[0031] When workpiece G is conveyed to the area below the second hoisting gantry 12, based on the inspection results, if workpiece G is qualified, the second hoisting gantry 12 can hoist workpiece G to the unloading station for unloading. If workpiece G is unqualified, the second hoisting gantry 12 can hoist workpiece G to the second conveyor line L2. The roller straightening device 30 can be set in the middle position of the second conveyor line L2. Workpiece G passes through the roller straightening device 30 on the second conveyor line L2 for roller straightening. The roller straightening device 30 can be equipped with multiple rollers for straightening workpiece G. The rollers form a straightening channel for workpiece G to pass through for straightening, and the spacing of the straightening channel is adjustable. After roller straightening, workpiece G will completely pass through the roller straightening device 30 and arrive below the first hoisting gantry 11, where it can be hoisted to the inspection station P1 for re-inspection.

[0032] In this embodiment, the workpiece G can be transferred in the second direction via the first hoisting gantry 11 and the second hoisting gantry 12, and transported in the first direction and its reverse direction via the first conveyor line L1, the second conveyor line L2 and the third conveyor line L3. The workpiece G can be degreased by the degreasing device 20 on the first conveyor line L1, by the roller straightening device 30 on the second conveyor line L2, and by the vision inspection device 40 at the inspection station P1. The whole process does not require manual transportation and inspection, has a high degree of automation, and is suitable for batch inspection and straightening of workpiece G.

[0033] In a preferred embodiment, the straightening device further includes multiple lifting devices 50, which can lift and lower the workpiece G and translate it along the second direction F2. Both the lifting and translating actions can be achieved by a cylinder. Each lifting device 50 may be equipped with a movable sliding support, which supports and drives the workpiece G to translate. When the vision inspection device 40 is located below the first hoisting truss 11, to avoid interference between the vision inspection device 40 and the first hoisting truss 11, the workpiece G at the inspection station P1 can be transferred to the third conveyor line L3 via the lifting device 50 located at the bottom.

[0034] In a preferred embodiment, a temporary storage station P2 for storing workpieces G is provided between the inspection station P1 and the second station. When there are many workpieces G, the workpieces G can be temporarily stored in the temporary storage station P2. The workpieces G on the temporary storage station P2 can be transferred to the inspection station P1 by the lifting device 50.

[0035] In a preferred embodiment, to more comprehensively inspect and correct the workpiece G, the corrective device further includes a flipping mechanism 60 for flipping the workpiece G. The flipping mechanism 60 includes a gripping unit for gripping the workpiece G and a drive source for rotating the gripping unit around a first direction F1. By flipping the workpiece G, the flipping mechanism 60 enables the workpiece G to be more comprehensively inspected and corrected. Specifically, flipping mechanisms 60 are provided at both ends of the second conveyor line L2 and on the inspection station P1.

[0036] In a preferred embodiment, it can be combined with Figure 7 The straightening equipment also includes a straightening device 70, which is located on the side of the second hoisting truss 12 away from the first hoisting truss 11. The workpiece G can be transported to the vicinity of the straightening device 70 via the third conveyor line L3. The straightening device 70 includes a first row of clamps 711 and a second row of clamps 712. The first row of clamps 711 and the second row of clamps 712 are arranged facing each other and each is provided with multiple pressure heads. The pressure heads press against the workpiece G to straighten the workpiece G.

[0037] Preferably, multiple pressure heads are arranged in an array, and the pressure heads on the first row of clamps 711 and the second row of clamps 712 are staggered. Each pressure head can be equipped with a drive source to perform targeted pressure and straightening on the position that needs to be straightened. More preferably, the drive source for driving the pressure head is an electric cylinder, which includes a motor and a lead screw linked to the motor. The pressure head is controlled to press against the workpiece G through the lead screw transmission, which enables the pressure head to move more accurately. After reaching the specified distance, it can have good self-locking properties and remain in the current position. The first row of clamps 711 and the second row of clamps 712 can also be equipped with a drive source to adjust the distance between the first row of clamps 711 and the second row of clamps 712. More preferably, in order to adapt to the large volume and weight of the first row of clamps 711 and the second row of clamps 712, the drive source for driving the first row of clamps 711 and the second row of clamps 712 is preferably a hydraulic cylinder.

[0038] Preferably, the straightening device further includes a return conveyor line L4, which is preferably a flow bar. The return conveyor line L4 is located between the second conveyor line L2 and the inspection station P1, and can be used to return the workpiece G straightened by the straightening device 70 to the area below the first hoisting gantry 11. The straightening device also includes a straightening station P3 for straightening the straightening device 70. The straightening station P3 is located between the third conveyor line L3 and the return conveyor line L4. The workpiece G on the third conveyor line L3 can be transferred to the straightening station P3 and the return conveyor line L4 by the lifting device 50.

[0039] In a preferred embodiment, the straightening device further includes a torsion-correcting device 80 for correcting the torsion of the workpiece G. The torsion-correcting device 80 is located on both sides of the straightening device 70 in the first direction F1. The straightening device also includes a torsion-correcting station P4 for correcting the torsion of the torsion-correcting device 80. The torsion-correcting station P4 is located between the straightening station P3 and the return conveyor line L4. The workpiece G on the torsion-correcting station P4 can be transferred to the return conveyor line L4 by the lifting device 50. Preferably, the third conveyor line L3, the straightening station P3, and the torsion-correcting station P4 are located between the first row of clamps 711 and the second row of clamps 712. The third conveyor line L3 and the workpiece G on it are located below the pressure head to avoid interference with the pressure head. (See reference...) Figure 7 The three workpieces G marked on the drawing are located, from bottom to top, on the third conveyor line L3, the straightening station P3, and the torsion station P4.

[0040] For specific details, please refer to Figure 8 The torsion adjustment device 80 includes a clamping member 81, a first driving member 82, a rotating member 83, and a second driving member 84. The clamping member 81 and the rotating member 83 each have a clamping portion on the same side, used to clamp the workpiece G. The first driving member 82 can drive the clamping member 81 to move along a first direction F1 and its opposite direction to adjust the clamping position. The second driving member 84 can drive the rotating member 83 to rotate around the first direction F1 to adjust the torsion of the workpiece G.

[0041] In a specific embodiment, a placement platform can be set below the inspection station P1, and multiple support frames can be set below the temporary storage station P2. The two sides of the support frames can limit the workpiece G, and the temporary storage station P2 can stack and store multiple workpieces G, preferably 2 or 3. Multiple support frames can also be set at the bottom of the straightening station P3.

[0042] In a preferred embodiment, the straightening device further includes a blocking mechanism 100, which is disposed on the third conveyor line L3. The blocking mechanism 100 includes a driving part and a blocking part. The driving part can drive the blocking part to extend to prevent the workpiece G from continuing to move along the first direction F1 on the third conveyor line L3. The blocking mechanism 100 is located between the second hoisting truss 12 and the straightening device 70. If the workpiece G needs to be straightened on the second conveyor line L2, when the workpiece G is transported to below the second hoisting truss 12, the blocking part of the blocking mechanism 100 can extend to block it.

[0043] The blocking portion can be configured to extend horizontally, extend from above, or extend from below. Preferably, the driving portion of the blocking mechanism 100 is located at the bottom of the third conveyor line L3, and the bottom of the third conveyor line L3 is provided with a through portion. When blocking is required, the blocking portion can pass through the through portion to block the workpiece G. The through portion can be a through hole, or the third conveyor can be a segmented structure, with the through portion being the interval between two adjacent segments.

[0044] In a preferred embodiment, since both the third conveyor line L3 and the return conveyor line L4 extend to the vicinity of the straightening device 70 and are relatively long, both the third conveyor line L3 and the return conveyor line L4 are preferably segmented structures, that is, a drive mechanism 90 is provided between adjacent segments, as can be seen from [reference needed]. Figure 6 The drive mechanism 90 includes an active roller 91 and a driven roller 92. The active roller 91 and the driven roller 92 cooperate to drive the workpiece G to move along the first direction F1. This design can avoid the third conveyor line L3 and the return conveyor line L4 being too long, which would cause inconvenience in maintenance if a fault occurs. In addition, multiple drive mechanisms 90 can provide power and can transport the workpiece G more smoothly.

[0045] In a specific implementation of the operation process, the first hoisting gantry 11 can hoist the workpiece G from the loading station to the first conveyor line L1. The workpiece G is transported back and forth on the first conveyor line L1 and is degreased by the degreasing device 20. After degreasing, the first hoisting gantry 11 can hoist the workpiece G to the temporary storage station P2. The workpiece G at the temporary storage station P2 can be transferred to the inspection station P1 by a set of lifting devices 50. Then, the vision inspection device 40 can inspect the workpiece G at the inspection station P1. After the vision inspection device 40 has inspected one side, the flipping mechanism 60 can flip the workpiece G so that the vision inspection device 40 can inspect the other sides of the workpiece G. After all sides of the workpiece G have been inspected, another set of lifting devices 50 can transfer the workpiece G to the third conveyor line L3. The third conveyor line L3 can transport the workpiece G to the area below the second hoisting gantry 12. At this time, according to the inspection results, the workpiece G can be sent to multiple transportation paths, as follows: According to the test results, if workpiece G needs to be straightened, the blocking mechanism 100 can block workpiece G to prevent it from continuing to be transported on the third conveyor line L3. Then, the second hoisting gantry 12 can hoist workpiece G to the second conveyor line L2 for straightening. After straightening, workpiece G will be transported to the bottom of the first hoisting gantry 11 under the drive of the second conveyor line L2, and then hoisted to the temporary storage station P2 by the first hoisting gantry 11. Then, the lifting device 50 will transfer workpiece G to the inspection station P1 for inspection. The lifting device 50 will then transfer the inspected workpiece G to the third conveyor line L3 for transport.

[0046] According to the test results, if the workpiece G meets the usage requirements, the blocking mechanism 100 can block the workpiece G to prevent it from continuing to be transported on the third conveyor line L3. Then the second hoisting gantry 12 can hoist the workpiece G to the unloading station.

[0047] According to the test results, if workpiece G needs to be straightened and / or twisted, the blocking mechanism 100 can allow workpiece G to pass through. When workpiece G is conveyed to the vicinity of the straightening device 70, the lifting device 50 can transfer workpiece G to the straightening station P3 for straightening and / or to the twisting station P4 for twisting. After straightening and / or twisting, workpiece G can be transferred by the lifting device 50 to the return conveyor line L4 and sent back to the bottom of the first hoisting truss 11 under the conveying of the return conveyor line L4. The first hoisting truss 11 and the lifting device 50 transfer workpiece G to the inspection station P1 for re-inspection. Then the lifting device 50 transfers workpiece G to the inspection station P1 again for inspection. The lifting device 50 then transfers the inspected workpiece G to the third conveyor line L3 for conveying.

[0048] In this embodiment, the equipment uses two hoisting gantry, multiple conveyor lines and multiple lifting devices to transfer and transport workpieces. Based on the test results, it can specifically combine roller straightening devices, straightening devices and / or torsion correction devices to straighten the workpieces, resulting in better and more comprehensive straightening effects.

[0049] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
