Description

Technical Field

[0001] The invention belongs to the technical field of aluminum part detection, and particularly relates to an aluminum part marking detection device. Background Art

[0002] With the development of modern industry, automated production lines are playing an increasingly important role in improving production efficiency, reducing production costs, and ensuring product quality. Aluminum parts, as a common industrial component in the manufacturing industry, are widely used in the automotive sector. However, the production of aluminum parts often presents a series of challenges, including how to efficiently conduct quality inspections to ensure product quality and how to improve production efficiency to meet market demand.

[0003] Traditional aluminum production lines often rely on manual operation or simple automated equipment, but this approach has several limitations. First, manual operation is associated with high labor costs, low efficiency, and susceptibility to human factors, hindering the continuous and stable operation of the production line. Second, traditional automated equipment often only performs simple production operations and struggles to meet complex production needs and quality requirements. Therefore, the design of an efficient and intelligent automated production line has become a pressing issue.

[0004] Against this backdrop, it's crucial to design an efficient automated production line for the inspection process in aluminum parts production, particularly for geometric tolerances, hardness testing, and the associated marking. This system must not only possess high-speed, high-precision inspection capabilities, but also intelligent operation and flexible production scheduling to accommodate the diverse specifications and requirements of aluminum parts.

[0028] (5) The hardness marking mechanism of the present invention can grab two batches of aluminum parts in one movement, thereby improving the efficiency of aluminum part transfer and thus improving the production efficiency of aluminum part marking. At the same time, a protective cover is provided around the pressure rod, and the pressure head of the pressure rod protrudes from the surface of the protective cover.

[0054] In order to deepen the understanding of the present invention, the present invention will be further described in detail with reference to the embodiments below. The following embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention. The mobile modules and other mechanisms mentioned in this application are all commonly used devices in the prior art, and their specific structures will not be repeated in this application.

[0055] like Figure 1-14 As shown, an aluminum part marking and detection device includes a feeding mechanism 1 and a discharging mechanism 2, and a form and position tolerance detection mechanism 3, a marking mechanism 4, a hardness meter dot marking mechanism 5 and a hardness detection mechanism 6 are sequentially arranged between the feeding mechanism 1 and the discharging mechanism 2. A first manipulator 8 is arranged between the form and position tolerance detection mechanism 3 and the marking mechanism 4, and the aluminum part 7 that has completed the form and position tolerance detection is grabbed from the form and position tolerance detection mechanism 3 to the marking mechanism 4. A second manipulator 9 is arranged between the marking mechanism 4 and the hardness meter dot marking mechanism 5, and the aluminum part 7 that has completed the marking is grabbed from the marking mechanism 4 to the hardness meter dot marking mechanism 5; the aluminum part 7 undergoes form and position tolerance detection, marking, marking detection, hardness meter dot marking, dot marking detection in sequence, and is finally discharged. One production line realizes comprehensive quality detection of the aluminum part 7, thereby improving the factory quality of the aluminum part 7.

[0056] A defective product discharging conveyor belt 101 is provided on one side of the form and position tolerance detection mechanism 3, the marking mechanism 4 and the hardness detection mechanism 6. The defective aluminum parts 7 detected are grabbed by a robot and put on the defective product discharging conveyor belt 101. The defective aluminum parts 7 detected by each mechanism are all transported out from the defective product discharging conveyor belt 101 and then recycled and reworked, which improves the utilization rate of defective products and saves production costs.

[0057] In some embodiments, the form and position tolerance detection mechanism 3 is equipped with an industrial computer 10 , the marking mechanism 4 is equipped with an industrial computer 10 , and the hardness meter marking mechanism 5 and the hardness detection mechanism 6 are equipped with an industrial computer 10 .

[0058] In the detection device of this embodiment, the form and position tolerance detection mechanism 3 and the marking mechanism 4 can be used as a separate device, so they are equipped with a separate industrial computer 10. When only form and position tolerance detection or marking operations are required, the form and position tolerance detection mechanism 3 or the marking mechanism 4 can be removed and used separately, which improves the flexibility of the detection device and saves production costs.

[0059] Please refer to Figure 16 、 17The feeding mechanism 1 includes a first conveyor belt 11, and an aluminum part selection mechanism is provided at the entrance of the first conveyor belt 11. The aluminum part selection mechanism includes a feeding platform 12, and a bracket 13 is provided on the feeding platform 12. A stopper 14 is detachably provided on the bracket 13. The lower edge of the stopper 14 is consistent with the shape of the upper surface of the aluminum part 7. A backrest 15 is provided on one side of the feeding platform 12, and an adjustment block 16 is slidably provided on the other side of the feeding platform 12. The adjustment block 16 cooperates with the backrest 15 to select the width of the aluminum part 7.

[0060] Specifically, since the upper surface of the aluminum part 7 in this embodiment is irregular, it is necessary to ensure that the aluminum part 7 is placed in the specified position for inspection. Therefore, the stop block 14 is set to a shape that fits the upper edge of the aluminum part 7. Only when the staff takes the correct aluminum part 7 and places it in the correct position can the aluminum part 7 pass through the stop block 14 and enter the subsequent inspection process, thereby improving the accuracy of the inspection process.

[0061] Furthermore, the stopper 14 is detachably connected to the bracket 13 by screws, and different stoppers 14 can be replaced according to the different specifications of the aluminum parts 7. The backrest 15 is fixed to the edge of one side of the feeding platform 12. When loading the aluminum parts 7, the adjustment block 16 is first adjusted to the appropriate position to ensure that the distance between the adjustment block 16 and the backrest 15 is the width of the aluminum parts 7, and then the aluminum parts 7 are loaded.

[0062] Please refer to Figure 4-8 The form and position tolerance detection mechanism 3 includes a first detection platform 31, four side form and position tolerance detection devices 32 arranged on the four sides of the first detection platform 31, and a bottom form and position tolerance detection device 33 located below the first detection platform 31, which is used to perform form and position tolerance detection on the four sides and bottom of the aluminum part 7; the four side form and position tolerance detection devices 32 are cross-shaped and surround the first detection platform 31, and the bottom form and position tolerance detection device 33 is located directly below the first detection platform 31. A through hole is opened on the first detection platform 31 to facilitate the bottom form and position tolerance detection device 33 to detect the aluminum part 7.

[0063] A third manipulator 34 is provided on the form and position tolerance detection mechanism 3. The third manipulator 34 grabs the aluminum part 7 from the feeding mechanism 1 to the first detection table 31. The side form and position tolerance detection equipment 32 is arranged on the horizontal module, including two movable detection parts 36 arranged upper and lower. The upper detection part 36 is raised and lowered above the lower movable detection part 36. A first central axis detection part 321 is provided between the two movable detection parts 36. The movable detection part 36 includes a first screw module 361, and two symmetrical sliders 362 are provided on the screw of the first screw module 361. A detection probe 363 is provided on the slider 362. The screw on the first screw module 361 is bounded by the center of the screw, and the threads on both sides are set in opposite directions.

[0064] Specifically, the movable detection portion 36 is arranged with the screw threaded on both sides in opposite directions with the screw center as the boundary, so that the detection probe 363 on the slider 362 can move closer or farther away simultaneously, which can adapt to aluminum parts 7 of different widths. The first central axis detection portion 321 is fixed and is also equipped with a detection probe 363 for detecting the middle of the side of the aluminum part 7. Because the aluminum part 7 has different widths and heights, the upper movable detection portion 36 is raised and lowered by the lifting module, which can adapt to the detection of aluminum parts 7 of different heights, thereby improving the versatility of side form and position tolerance detection.

[0065] The bottom surface form and position tolerance detection device 33 is mounted on the lifting module and includes a movable detection unit 36. A second central axis detection unit 331 is positioned between two sliders 362 of the movable detection unit 36. The principle of the bottom surface form and position tolerance detection device 33 is the same as that of the side surface form and position tolerance detection device 32. Similarly, the screw on the movable detection unit 36 ​​is arranged with the threads on both sides of the screw center as the boundary, so that the detection probe 363 on the slider 362 can move closer or farther at the same time, which can accommodate aluminum parts 7 with different bottom widths.

[0066] Please refer to Figure 9 The marking equipment 41 includes a marking table 411 and a marking machine 412. The detection mechanism 42 includes a second detection table 421 and a detection camera 422. A vacuum cleaner 43 is provided on one side of the marking table 411, and two air blowers 44 are provided on the other side of the marking table 411. The two air blowers 44 are arranged facing the marking table 411.

[0067] Specifically, a fourth manipulator 413 is provided on one side of the marking table 411 and the marking machine 412. The fourth manipulator 413 grabs the marked aluminum part 7 onto the marking table 411. The aluminum part 7 to be marked is placed on the marking table 411. The marking machine 412 is driven by a three-axis mobile module and approaches the aluminum part 7 to accurately mark it. The marking head in this embodiment is a pneumatic pen. Of course, in other embodiments, laser marking can also be used based on cost investment. In this embodiment, visual inspection is used to detect the marking on the aluminum part 7. The CCD captures images to detect the position and content of the marking to ensure the quality of the marking.

[0068] In a preferred embodiment, two air blowers 44 are respectively arranged at the two corners on the other side of the marking table 411. The two air blowers 44 are arranged facing the marking table 411 and are placed at a 45-degree angle to the marking table 411, ensuring that the aluminum chips generated by marking can be blown to the vacuum cleaner 43, thereby ensuring the production environment.

[0069] Please refer to Figure 10-12The hardness marking mechanism 5 includes a hardness marking machine 51 and a gripping mechanism 52. The gripping mechanism 52 grabs the aluminum part 7 and places it into the hardness marking machine 51 for marking, and then takes out the aluminum part 7 after marking. Among them, there are several hardness marking machines 51, and a second conveyor belt 53 and a third conveyor belt 54 are provided on both sides of the hardness marking machine 51. The second conveyor belt 53 is used to transport the aluminum parts 7 after marking, and the third conveyor belt 54 is used to transport the aluminum parts 7 after marking. The gripping mechanism 52 includes a crossbeam 521 that is movably arranged above the second conveyor belt 53 and the third conveyor belt 54. A first clamping jaw group 522 and a second clamping jaw group 523 are symmetrically provided on both sides of the crossbeam 521. The first clamping jaw group 522 and the second clamping jaw group 523 are both provided with a first clamping jaw 55 with the same number as the hardness testing mechanism 51.

[0070] Specifically, in this embodiment, there are 6 hardness marking mechanisms 5 equidistantly arranged with an interval of 280 mm, and 6 first clamps 55 are also provided on the first clamp group 522 and the second clamp group 523. When in use, the aluminum parts 7 to be marked are placed in the second conveyor belt 53 in turn. In this embodiment, 6 aluminum parts 7 can be marked in turn, and 6 aluminum parts 7 are placed in turn. After all aluminum parts 7 are moved to the designated position, the first start-up, the first clamp group 522 first clamps the aluminum parts 7 to be marked and puts them into the hardness marking mechanism 5 for marking. The second conveyor belt 53 continues to feed, and the first clamp group 522 moves to the top of the second conveyor belt 53 to clamp the next batch of aluminum parts 7. At the same time, the second clamp group 523 moves down to clamp the aluminum parts 7 that have been marked. After both the first clamping group 522 and the second clamping group 523 have successfully clamped, the crossbeam 521 moves, and the first clamping group 522 is located above the hardness marking mechanism 5, and the next batch of aluminum parts 7 are placed into the hardness marking mechanism 5 for marking. The second clamping group 523 is located above the third conveyor belt 54, and the aluminum parts 7 that have been marked are placed on the third conveyor belt 54 for transmission to the subsequent inspection process, and the cycle continues.

[0071] Furthermore, in this embodiment, the second conveyor belt 53 and the third conveyor belt 54 are driven by a servo motor and a planetary reducer, and the moving accuracy of the conveyor belts is improved. At the same time, 6 position sensors are provided on both sides of the second conveyor belt 53 and the third conveyor belt 54 at a fixed distance of 280 mm, which can ensure the precise positioning of the aluminum part 7. The grasping mechanism 52 successfully clamps the aluminum part 7, thereby improving the marking efficiency.

[0072] As another embodiment of further optimization, the hardness dotting machine 51 includes a box body 511, a slide rail and a slider are provided on the box body 511, a dotting platform 512 is provided on the slider, a pressure cylinder 513 is provided on one side of the dotting platform 512, and a pressure rod 514 is provided on the other side of the dotting platform 512. A protective cover 515 is provided around the pressure rod 514, and the pressure head of the pressure rod 514 protrudes from the surface of the protective cover 515.

[0073] Specifically, the aluminum part 7 is placed on the dotting platform 512, with the dotting surface facing the pressure rod 514. The pressure cylinder 513 is then activated to push the dotting platform 512, thereby squeezing the aluminum part 7 toward the pressure rod 514, completing the dotting process. The dotting diameter is then measured to determine whether the hardness of the aluminum part 7 meets the requirements. The protective cover 515 protects the pressure rod 514, preventing excessive intrusion of the aluminum part 7 and improving the safety of the dotting process.

[0074] Please refer to Figure 13-15 The hardness detection mechanism 6 includes a dislocation mechanism 61 and a third detection platform 62. The dislocation mechanism 61 grabs the aluminum part 7 that has been dotted and places it on the third detection platform 62. A visual detection device 63 is provided on one side of the third detection platform 62 for detecting the concave spots on the aluminum part 7. The diameter of the concave spots is detected to determine whether the hardness of the aluminum part 7 meets the standard, with high accuracy.

[0075] The dislocation mechanism 61 includes a second clamp 611 and a third clamp 612 which are arranged in parallel and lifted on the horizontal module. When the second clamp 611 grabs the aluminum part 7 that has been dotted and puts it on the third inspection platform 62, the third clamp 612 grabs the aluminum part 7 that has been inspected and puts it on the discharging mechanism 2, thereby realizing the dislocation grabbing of the aluminum part 7 and improving the inspection efficiency.

[0076] Furthermore, a horizontal moving mechanism 613 is provided on the third clamp 612, which can drive the third clamp 612 to move in a moving direction perpendicular to the dislocation mechanism 61. When a defective aluminum part 7 is detected, the third clamp 612 can grab the aluminum part 7 and place it on the defective product discharge conveyor belt 101 under the drive of the horizontal moving mechanism 613. The discharge of defective products can be completed without the need for an additional robot.

[0077] Furthermore, a cross workbench 64 is provided under the visual inspection device 63. In actual use, the operator can accurately adjust the inspection position of the visual inspection device 63 according to the different specifications of the aluminum parts 7 or the hardness inspection points at different positions, thereby further improving the accuracy of the hardness inspection.

[0078] The device of the present invention is also provided with a number of sensors, such as position sensors, proximity switches and other devices for realizing automatic operation of the device. The settings of these sensor devices are conventional technologies in this field and will not be described in detail in this application.
