Abstract
Description
Technical Field
[0001] This invention belongs to the field of detection technology, specifically relating to testing using optical means, and particularly to a detection device and method for metal plugs used in tractors. Background Technology
[0002] In the new energy industry, especially in battery module production, the top and bottom covers of cylindrical batteries are circular end pieces, and the diameter of the circular end pieces must be consistent during the production process.
[0003] In related technologies, to ensure the stability of the circular end piece supported by the tray, placement holes for limiting the circular end piece are usually made on the tray. The inner diameter of the placement hole is usually slightly larger than the diameter of the circular end piece (the gap is about 0.5-1mm). When the circular end piece is placed into the placement hole, it is easy for it to tilt due to contact with the inner wall of the placement hole.
[0004] When using a robotic arm to handle circular end pieces, insufficient contact between the negative pressure adsorption surface of the robotic arm and the surface of the circular end piece can lead to slippage during handling. When the robotic arm handles a tilted circular end piece to the detection probe, the tilted end piece cannot be accurately placed into the detection station, resulting in an increased error rate during detection and causing technical problems such as misjudgment.
[0005] Based on this, it is necessary to design a metal plug detection device and detection method for tractor vehicles.
[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore, the above description is not considered to constitute information related to the technology. Summary of the Invention
[0007] This disclosure provides at least one device and method for detecting metal plugs used in tractors.
[0008] In a first aspect, embodiments of this disclosure provide a metal plug detection device for tractor vehicles, comprising: A rotating platform, which is set to rotate on a worktable and has several inspection stations evenly distributed around its circumference; The detection component is located on one side of the rotating platform; The loading robot is located on the side of the rotating platform away from the detection components and is used for negative pressure handling of circular end pieces; A tray assembly, positioned on one side of the rotating platform, for holding circular end pieces, includes: The material tray is horizontally positioned and has several placement holes arranged in a matrix. The leveling module is radially slidably disposed within the placement hole; The driving component, whose lifting mechanism is located below the material tray, is linked to the leveling module; Among them, the driving component moves downward to drive the leveling module to slide radially outward so that the circular end piece falls into the placement hole; As the drive unit moves upward, the leveling module slides radially inward to correct the circular end piece so that it is placed horizontally. A loading robot uses negative pressure to transport circular end pieces to the inspection station, where the inspection component is adapted to check whether the dimensions of the circular end pieces are qualified.
[0009] In one optional embodiment, the tray has a plurality of receiving cavities, which are coaxially arranged with the placement hole and have an inner diameter larger than the placement hole; The leveling module includes: a slider, which is slidably disposed in the receiving cavity, and the inner wall is provided with an arc surface that matches the circular end piece; A tension spring, with its two ends respectively disposed on the inner wall of the receiving cavity and the outer wall of the slider; When the driving component moves upward, it pushes the slider to slide radially inward. When the drive component moves downward, the tension spring pulls the slider to slide radially outward.
[0010] In one optional embodiment, a first inclined surface is provided on the lower part of the outer wall of the slider, and the angle between the first inclined surface and the horizontal plane is 55°±2°.
[0011] In one optional embodiment, the driving component includes: a driving plate, which is disposed parallel to the bottom wall of the material tray and has a gap with the bottom wall of the material tray; Several oil draining platforms are mounted on the drive plate and are raised and lowered within the receiving cavity; The second inclined surface is located on the side wall of the oil draining platform and matches the first inclined surface; When the drive plate moves upward, the second inclined surface abuts against the first inclined surface to push each of the sliders to slide radially inward.
[0012] In one optional embodiment, an oil storage cavity is formed within the drive plate; The drive plate has several oil holes, which are connected to the oil storage cavity and are located below the slider. When the drive plate moves downward, the tension spring pulls the slider to slide radially outward to open the oil hole, and the oil on the oil draining platform flows into the oil storage chamber through the oil hole.
[0013] In one optional embodiment, a drive cylinder is provided on the worktable, and the piston rod end of the drive cylinder is fixed to the bottom wall of the drive plate.
[0014] In one optional embodiment, a liquid level sensor is provided in the oil storage chamber, which triggers an alarm when the accumulated oil exceeds a threshold. An oil pipe is provided on the side wall of the drive plate, and the oil pipe is connected to the oil storage cavity.
[0015] In one optional embodiment, the negative pressure suction cup of the loading robot is connected to a multi-stage buffer cylinder with a buffer stroke of 10-15mm, which is used to compensate for the placement height tolerance of the circular end piece.
[0016] In one optional implementation, the detection component includes: The testing bracket is vertically mounted on the worktable. Eddy current thickness gauge, which is fixed to the side wall of the testing bracket; An optical imaging unit is fixed to the side wall of the detection bracket and located above the eddy current thickness gauge. The rotating platform drives the circular end piece to move to the detection station. The eddy current thickness gauge and the optical imaging unit are used to measure the oil layer thickness and capture the surface coverage uniformity, respectively.
[0017] Secondly, this disclosure also provides a detection method for a metal plug detection device for tractor vehicles, the detection method comprising: The driving component moves downwards, causing the leveling module to slide radially outwards, so that the circular end piece falls into the placement hole; As the drive unit moves upward, the leveling module slides radially inward to correct the circular end piece so that it is placed horizontally. A loading robot uses negative pressure to transport the circular end piece to the inspection station. A rotating platform drives the circular end piece to rotate to the inspection station. The inspection component is suitable for detecting whether the size of the circular end piece is qualified.
[0018] The beneficial effects of this invention are that it provides a metal plug detection device and method for tractor vehicles. Through the cooperation of a tray assembly, a loading robot, and a detection component, before detection, the leveling module and a driving component work together. The driving component moves upward, driving the leveling module to move radially inward, achieving automatic correction of the horizontality of the circular end piece, completely solving the problem of the circular end piece tilting due to the gap in the placement hole. The horizontal circular end piece not only improves the stability of the negative pressure adsorption of the loading robot but also ensures the detection accuracy of the detection probe.

[0029] Research has revealed that in related technologies, to ensure the stability of the circular end piece supported by the tray, placement holes for limiting the circular end piece are typically made on the tray. The inner diameter of the placement hole is usually slightly larger than the diameter of the circular end piece (the gap is approximately 0.5-1mm). (If the inner diameter of the placement hole is too large, although it can prevent the circular end piece from tilting after being placed in, it cannot ensure that the axis of the circular end piece is nearly coincident with the axis of the placement hole. This affects the positioning accuracy of the circular end piece when it is placed at the processing station after the robot arm has applied negative pressure to it.) When the circular end piece is placed into the placement hole, it is prone to tilting due to contact with the inner wall of the placement hole, resulting in insufficient contact between the negative pressure adsorption surface of the robot arm and the surface of the circular end piece, leading to slippage during handling. The tilted circular end piece cannot be accurately placed into the inspection station by the robot (because the outer wall of the circular end piece is limited by the inner wall of the placement hole, causing its axis to be misaligned with the axis of the robot's negative pressure suction cup. Therefore, when the circular end piece is placed with the axis of the negative pressure suction cup as the reference point, the circular end piece cannot accurately detect the axis of the inspection station), which increases the error rate during inspection and causes technical problems of misjudgment.
[0030] In related technologies, existing solutions (such as directional arrangement of vibratory discs) cannot adapt to the deformation characteristics of thin-walled circular end pieces, and positioning is time-consuming in high-speed detection scenarios, resulting in low efficiency.
[0031] Based on this, it is necessary to design a metal plug detection device and detection method for tractor vehicles.
[0032] The defects in the above solutions and the reasons for their occurrence are the results of the inventors' practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventors' contributions to this disclosure.
[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0034] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0035] like Figures 1 to 7 As shown, at least one embodiment provides a metal plug detection device for tractor vehicles, comprising: A rotating platform 1 is rotatably mounted on a workbench 5 and has several inspection stations 10 evenly distributed around its circumference. The rotating platform 1 is fixed to the workbench 5 by a servo motor. The rotating platform 1 has at least 6 inspection stations 10 evenly distributed around its circumference, with a station spacing accuracy of ±0.05mm.
[0036] Reference Appendix Figure 7 The detection component 2 is disposed on one side of the rotating platform 1. The detection component 2 includes: a detection bracket 21, which is vertically disposed on the worktable 5; an eddy current thickness gauge 22, which is fixed to the side wall of the detection bracket 21, the eddy current thickness gauge 22 having an accuracy of ±0.55μm, and the distance between the eddy current thickness gauge 22 and the workpiece is 3mm when the circular end piece moves to the detection station; and an optical imaging unit 23, which is fixed to the side wall of the detection bracket 21 and located above the eddy current thickness gauge 22. The optical imaging unit 23 is a 5-megapixel CCD and a strobe light source. The rotating platform 1 drives the circular end piece to move to the detection station. The eddy current thickness gauge 22 and the optical imaging unit 23 are used to measure the oil layer thickness and capture the surface coverage uniformity, respectively.
[0037] Reference Appendix Figure 6 A loading robot 3 is positioned on the side of the rotating platform 1 away from the detection component 2, and is used for negative pressure handling of circular end pieces. The negative pressure suction cup 31 of the loading robot 3 is connected to a multi-stage buffer cylinder 32, with a buffer stroke of 10-15mm, used to compensate for the placement height tolerance of the circular end pieces. The negative pressure suction cup 31 is connected to a three-stage buffer cylinder 32 with a vacuum pressure of -80kPa.
[0038] Reference Appendix Figure 3 The tray assembly 4, located on one side of the rotating platform 1, is used to hold circular end pieces and includes: a material tray 41, horizontally positioned with a matrix of placement holes 410; a leveling module 42, radially slidable within the placement holes 410; and a driving component 43, vertically positioned below the material tray 41 and linked with the leveling module 42. When the driving component 43 moves downward, it drives the leveling module 42 to slide radially outward, causing the circular end pieces to fall into the placement holes 410. When the driving component 43 moves upward, the leveling module 42 slides radially inward to correct the circular end pieces, ensuring they are placed horizontally. A loading robot 3 uses negative pressure to transport the circular end pieces to the inspection station 10. The inspection component 2 is suitable for inspecting whether the dimensions of the circular end pieces are within acceptable limits. In this embodiment, the circular end pieces are the raw material for cylindrical batteries. During storage, the circular end pieces often require oiling to prevent rusting.
[0039] Reference Appendix Figure 4The tray 41 has several receiving cavities 411, which are coaxially arranged with the placement hole 410 and have an inner diameter larger than that of the placement hole 410. The diameter of the receiving cavity 411 is 5-10 mm larger than that of the placement hole 410. The leveling module 42 includes a slider 421, which is slidably disposed in the receiving cavity 411. The inner wall of the slider 421 is provided with an arc surface that matches the curvature of the circular end piece. A limiting block 424, which is T-shaped, is provided on the top wall of the slider 421. Several sliding grooves adapted to the limiting block 424 are radially formed on the inner top wall of the receiving cavity 411. One limiting block 424 corresponds to one sliding groove. The extension direction of the sliding groove is consistent with the extension direction of the tension spring 422. The engagement of the limiting block 424 and the sliding groove ensures that the slider 421 can only move horizontally within the receiving cavity 411. When the drive plate 431 moves downward, the engagement of the limiting block 424 and the sliding groove prevents the slider 421 from moving downward. A first inclined surface 423 is provided on the lower part of the outer wall of the slider 421, and the angle between the first inclined surface 423 and the horizontal plane is 55°±2°. Figure 5 In this context, 'a' represents the angle between the first inclined plane 423 and the horizontal plane. A tension spring 422 has its two ends respectively disposed on the inner wall of the receiving cavity 411 and the outer wall of the slider 421; the tension spring 422 has a stiffness coefficient of 1.2 N / mm and a preload of 5 N. When the driving member 43 moves upward, it pushes the slider 421 to slide radially inward; when the driving member 43 moves downward, the tension spring 422 pulls the slider 421 to slide radially outward.
[0040] Continue to refer to the appendix Figure 4 The driving component 43 includes: a driving plate 431, which is parallel to the bottom wall of the material tray 41 and has a gap with the bottom wall of the material tray 41; a driving cylinder 44 adapted to drive the driving plate 431 to move up and down relative to the material tray 41. A plurality of oil draining tables 432 are disposed on the driving plate 431 and are vertically and vertically disposed within the receiving cavity 411; a second inclined surface 433 is located on the side wall of the oil draining table 432 and matches the first inclined surface 423. (See attached diagram) Figure 5 When the drive plate 431 moves upward, the second inclined surface 433 abuts against the first inclined surface 423, pushing each of the sliders 421 to slide radially inward. When the drive plate 431 moves downward, Figure 5 F1 in the figure represents the force that drives the plate 431 to move downward; the second inclined surface 433 disengages from the first inclined surface 423, and the tension spring 422 pulls the slider 421 to slide radially outward to open the oil hole 435. Figure 5F2 represents the outward sliding force on slider 421. An oil storage cavity 434 is formed within the drive plate 431; several oil holes 435 are formed on the drive plate 431, communicating with the oil storage cavity 434 and located below slider 421; when the drive plate 431 moves downward, the tension spring 422 pulls slider 421 radially outward to open the oil holes 435, allowing oil on the oil draining platform 432 to flow into the oil storage cavity 434 through the oil holes 435. The drive cylinder 44 pushes the drive plate 431 upward, causing the second inclined surface 433 of the oil draining platform 432 to contact the first inclined surface 423 of slider 421, thereby generating a radial thrust to cause each slider 421 to slide radially inward. This inward sliding of slider 421 is suitable for correcting the circular end piece, thereby improving the levelness of the circular end piece.
[0041] Please refer to the appendix again. Figure 4 The oil storage chamber 434 is equipped with a liquid level sensor, which triggers an alarm when the accumulated oil exceeds a threshold. An oil drain pipe is provided on the side wall of the drive plate 431, and the oil drain pipe is connected to the oil storage chamber 434. The oil drain pipe is connected to a negative pressure recovery device. When the liquid level sensor detects that the accumulated oil exceeds the threshold, the negative pressure recovery device draws the oil from the oil storage chamber 434 under negative pressure.
[0042] Reference Appendix Figure 2 A drive cylinder 44 is provided on the worktable 5, and the piston rod end of the drive cylinder 44 is fixed to the bottom wall of the drive plate 431. The drive cylinder 44 is used to drive the drive plate 431 to move up and down.
[0043] At least one embodiment provides a detection method for a metal plug detection device for tractor vehicles, the detection method comprising: The driving component 43 moves downward and drives the leveling module 42 to slide radially outward so that the circular end piece falls into the placement hole 410; When the drive unit 43 moves upward, the leveling module 42 slides radially inward to correct the circular end piece so that it is placed horizontally; The loading robot 3 uses negative pressure to transport the circular end piece to the inspection station 10. The rotating platform 1 drives the circular end piece to rotate to the inspection station. The inspection component 2 is suitable for detecting whether the size of the circular end piece is qualified.
