[0002] The automation of laser marking and scanning inspection of automotive parts is an inevitable choice for the development of the machinery manufacturing industry, especially the automotive industry. At present, the laser marking and scanning inspection of parts (such as parking gears) is generally carried out manually, and then the parts are transferred to the next set of processes for manual scanning inspection.

[0003] Current laser marking and barcode scanning detection methods have the following problems:

[0004] 1) Manual operation is inefficient;

[0005] 2) The process involves multiple steps, including marking and scanning.

[0006] 3) Manual operation, especially the barcode scanning and detection process, is difficult to control in terms of stability and is prone to missed detection and incorrect detection.

[0007] Therefore, it is necessary to develop an automatic loading and unloading laser marking and scanning detection device to solve the above-mentioned technical problems. Utility Model Content

[0008] The technical problem to be solved by this utility model is to provide an automatic loading and unloading laser marking and scanning detection device, which effectively overcomes the defects of the prior art.

The first rotary drive mechanism is mounted on the upper end of the loading platform, and the turntable is positioned above the first rotary drive mechanism. The first rotary drive mechanism is connected to the lower center of the turntable and is used to drive the turntable to rotate. Multiple storage racks are evenly spaced around the center of rotation on the turntable. Through holes are provided on the turntable corresponding to the position of each storage rack. Multiple ejector mechanisms are respectively mounted at each through hole at the lower end of the turntable. A top plate is provided inside each storage rack.

[0027] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0028] Example

[0029] like Figure 1 , 2 As shown in Figure 3, the automatic loading and unloading laser marking and scanning detection equipment of this embodiment includes a loading platform 1, an unloading platform 2, a worktable 3, an automatic loading and unloading mechanism 4, a scanning and detection device 5, a laser marking device 6, and a general loading fixture 7. The scanning and detection device 5 and the laser marking device 6 are respectively mounted at intervals above the worktable 3. The general loading fixture 7 is mounted on the loading platform 1. The automatic loading and unloading mechanism 4 is used to obtain the workpieces stored on the general loading fixture 7 and transfer them to the worktable 3. The automatic loading and unloading mechanism 4 is also used to obtain the marked and scanned workpieces on the worktable 3 and transfer them to the unloading platform 2.

[0030] In this embodiment, the automatic loading and unloading laser marking and scanning inspection equipment automatically places workpieces on the universal loading fixture 7. The automatic loading and unloading mechanism 4 then retrieves individual workpieces from the fixture 7 and transfers them to the worktable 3. The laser marking device 6 and the scanning and inspection device 5 above the worktable 3 perform laser marking and scanning operations on the workpieces, respectively. Afterward, the automatic loading and unloading mechanism 4 retrieves the processed workpieces from the worktable 3 and transfers them to the unloading platform 2 for stacking. The entire process automates loading, processing, and unloading, significantly improving operational efficiency compared to traditional technologies.

[0031] In a preferred embodiment, the automatic feeding and unloading mechanism 4 includes an industrial robot 41 and a suction cup assembly 42, wherein the end effector of the industrial robot 41 is connected to the suction cup assembly 42 via a rotating mechanism.

[0032] In the above implementation scheme, the industrial robot 41 is connected to a control system, which can autonomously complete the rotation, and adjust the position and height of the end effector according to the parameters set by the control system. This enables the suction cup assembly 42 to move to the general loading fixture 7, the worktable 3, and the unloading table 2 under the operation of the industrial robot 41. In addition, the suction cup assembly 42 can effectively pick up workpieces from above, or release them after the suction stops.

[0033] In this embodiment, the industrial robot 41 can be a six-axis robot of an appropriate model, and the end effector is a conventional component of the existing robot end effector, which will not be described in detail here.

[0034] The suction cup assembly 42 is adapted to the shape of the workpiece. Its shape generally includes a suction plate and multiple suction nozzles set at the bottom of the suction plate. The suction nozzles can be connected to the adapted negative pressure channel in the suction plate or directly connected to the negative pressure device through pipelines. This is a conventional technology and will not be described in detail here.

[0035] In this embodiment, a rotary motor (i.e., the aforementioned rotating mechanism) is installed on the end effector of the industrial robot 41. A rectangular base is connected to the lower part of the rotary motor, and a suction plate is provided at each end of the base. The purpose of this is twofold: first, to balance the rotation of the rotary motor at the end effector; and second, to allow switching between two different types of suction cup assemblies 42 to achieve the suction and transfer of various types of parts. However, it should be noted that only one set of suction cup assemblies 42 is used to adsorb the workpiece during a single operation.

[0036] In a preferred embodiment, the general-purpose loading fixture 7 includes a turntable 71, a first rotary drive mechanism 72, multiple storage racks 73, and multiple ejector mechanisms 74. The first rotary drive mechanism 72 is mounted on the upper end of the loading platform 1, and the turntable 71 is disposed above the first rotary drive mechanism 72. The first rotary drive mechanism 72 is connected to the lower middle part of the turntable 71 and is used to drive the turntable 71 to rotate. Multiple storage racks 73 are evenly spaced around the rotation center of the turntable 71. Through holes are provided on the turntable 71 at each position corresponding to every storage rack 73. The multiple ejector mechanisms 74 are respectively mounted one-to-one at each through hole at the lower end of the turntable 71. A top plate 7311 is provided inside the storage rack 73. The pushing end of the ejector mechanism 74 passes through the through hole and approaches or contacts the top plate 7311. Workpieces are stacked in the storage rack 73 and located on the upper end of the top plate 7311.

[0037] In the above embodiment, multiple workpieces are stacked vertically on any of the storage racks 73 or all of the storage racks 73 on the turntable 71. During operation, the first rotary drive mechanism 72 drives the turntable 71 to rotate, causing one of the storage racks 73 containing workpieces to rotate to a position close to the industrial robot 41 (i.e., the virtual loading station). The industrial robot 41 can then move its end effector and suction cup assembly 42 to above the storage rack 73 at this station, thereby using the suction cup assembly 42 to adsorb the uppermost workpiece of the storage rack 73. Then, the workpiece is transferred to the inspection position on the workbench 3 by the operation of the industrial robot 41. After each workpiece is removed, the lower ejector mechanism 74 drives its ejector end to move upward, lifting the top plate 7311 by the height of one workpiece. This causes the topmost workpiece to move upward by the height of one workpiece, waiting to be removed, until all the workpieces in the storage rack 73 are removed. Then, the turntable 71 is driven to rotate by the first rotation drive mechanism 72, causing the next storage rack 73 containing workpieces to move to the virtual loading station to wait for the workpieces to be removed one by one. Overall, continuous loading operation can be achieved, and the design is relatively reasonable.

[0038] In this embodiment, the top-loading mechanism 74 adopts an appropriate model of electric screw jack. The screw of the electric screw jack is vertically upward, and the upper end is connected to a push plate (a in the figure). On the upper end of the loading platform 1 below the turntable 71, near the periphery of the position where each electric screw jack is stopped, two photoelectric sensors (b and c in the figure) are arranged vertically and horizontally through a rod (h in the figure). The higher one is used to detect the lower limit height of the push plate's retraction. When the screw (d in the figure) descends, and the push plate descends to below the upper photoelectric sensor, the control system receives the signal from the photoelectric sensor and controls the electric screw jack to stop descending. When the screw rises, and the lower end of the screw rises to above the lower photoelectric sensor, the control system receives the signal from the photoelectric sensor and controls the electric screw jack to stop rising. The two photoelectric sensors can be used to define the upper and lower limit positions of the screw's vertical movement.

[0039] In a preferred embodiment, a vertical rod is provided above the center of the turntable 71, and a stacking detector (M in the figure) is provided at the upper end of the vertical rod. The stacking detector is used to detect whether the workpieces that have been adsorbed by the suction cup assembly 42 and moved to its upper part are stuck together.

[0040] In the above implementation scheme, each time the industrial robot 41 takes the top workpiece from the virtual loading station, it will move the picked-up workpiece to a specific height above the stacking detector. If two stacked workpieces are picked up at the same time, the height between the bottom surface of the workpiece and the stacking detector will decrease and be sensed by the stacking detector to determine whether "stacking" has occurred during the adsorption process.

[0041] It should be noted that in this embodiment, the stacking detector uses a compatible proximity switch. Throughout the entire processing operation, the end effector of the industrial robot 41 remains at a consistent height above the stacking detector. Therefore, if only one workpiece is picked up, the height between the bottom surface of the workpiece and the proximity switch is consistent and will not be detected. However, if two stacked workpieces are picked up, the distance between the bottom surface of the workpiece and the proximity switch decreases, or even touches the proximity switch, which will then be detected. This is used to determine whether a "stacking" phenomenon has occurred when picking up workpieces. If it occurs, the machine stops and waits until operator intervention restores normal operation.

[0042] In a preferred embodiment, the first rotary drive mechanism 72 is an electric rotary bearing or a DD motor. The turntable 71 has a hole in its center. The upright passes through the hole in the center of the turntable 71 and the hole in the center of the first rotary drive mechanism 72, and is connected and fixed to the loading platform 1.

[0043] In the above implementation scheme, the main purpose of this design is to ensure that the uprights do not rotate during the rotation of the turntable 71.

[0044] As a preferred implementation method, such as Figure 2 As shown, the industrial robot 41 is mounted on the loading platform 1. The edge of the turntable 71 near the industrial robot 41 is provided with a fixing rod that is fixed to the loading platform 1. A pair of first through-beam photoelectric sensors (f in the figure) and a pair of second through-beam photoelectric sensors (g in the figure) are provided on the upper part of the side of the fixing rod and the upright that are close to each other. The pair of first through-beam photoelectric sensors are set at the same height, and the pair of second through-beam photoelectric sensors are set at the same height, and the height of the first through-beam photoelectric sensors is higher than that of the second through-beam photoelectric sensors.

[0045] In the above implementation scheme, a pair of first-beam photoelectric sensors are used to detect whether the topmost workpiece has been pushed into place after the top-mounting mechanism 74 pushes the stacked workpieces in the storage rack 73 upwards. Specifically, when the topmost workpiece in the storage rack 73 at the virtual loading station is removed, the pair of first-beam photoelectric sensors can normally emit and receive infrared light (the height at which the infrared light emitted by the pair of first-beam photoelectric sensors is exactly at the height when the topmost workpiece is pushed to the removal height), indicating that the pushing is in place, and will feed the signal back to the control system, which will then control the top-mounting mechanism 74 connected to it to stop operating; when the turntable 71 rotates, causing other storage racks to rotate, the topmost workpiece is pushed into place. When rack 73 is moved to the virtual loading station, if there is no workpiece inside, a pair of second through-beam photoelectric sensors will normally emit and receive infrared light. This signal will be fed back to the control system, which will determine that rack 73 is in control mode and control the first rotary drive mechanism 72 to continue rotating at a certain angle, so that the next rack 73 rotates to the virtual loading station. If rack 73 is also empty, the turntable 71 continues to rotate. If there is a workpiece, the infrared emission path of the pair of second through-beam photoelectric sensors is blocked. After receiving the signal, the control system will control the first rotary drive mechanism 72 to stop running, and the industrial robot 41 can pick up the material normally.

[0046] It should be noted that the storage rack 73 is a hollow frame, so the infrared rays of a pair of first through-beam photoelectric sensors and a pair of second through-beam photoelectric sensors can pass through the storage rack 73.

[0047] In a preferred embodiment, the storage rack 73 includes a base plate 731 and two outer frame side plates 732. The base plate 731 is mounted on the upper end of the turntable 71 and has a through hole for the pushing end of the top material mechanism 74 to pass through. The two outer frame side plates 732 are respectively fixed vertically and parallel to each other on the upper end of the base plate 731 and distributed on both sides of the through hole. The top plate 7311 is horizontally arranged between the two outer frame side plates 732, and the two ends of the top plate 7311 are slidably connected to the two outer frame side plates 732 respectively. The workpiece is embedded and stacked between the two outer frame side plates 732 and can be moved upward relative to the outer frame side plates 732 for removal.

[0048] In the above implementation, after each storage rack 73 rotates and stops at the virtual loading station, the two outer frame side plates 732 are distributed on both sides of the infrared path of a pair of second through-beam photoelectric sensors, which will not block the infrared light. Furthermore, the height of the pair of first through-beam photoelectric sensors and the pair of second through-beam photoelectric sensors is higher than the height of the upper surface of the base plate 731.

[0049] In a preferred embodiment, the upper end of the workbench 3 is equipped with a second rotary drive mechanism and a rotary platform 8. The second rotary drive mechanism is connected to the lower middle part of the rotary platform 8. Two workstations are provided at the upper parts of both ends of the rotary platform 8. The second rotary drive mechanism is used to drive the rotary platform 8 to rotate horizontally, and to move the two workstations to the bottom of the barcode scanning and detection device 5 and the laser marking device 6, respectively.

[0050] In the above implementation scheme, under normal conditions, the two stations of the rotating platform 8 are located below the barcode scanning and detection device 5 and the laser marking device 6, respectively. Each time the second rotating drive mechanism drives the rotating platform 8, it rotates 180°, so that the two stations are switched, ensuring that the stations are always below the barcode scanning and detection device 5 and the laser marking device 6 after the operation stops, thus ensuring the normal operation of laser marking and barcode scanning.

[0051] In this embodiment, the second rotary drive mechanism uses a motor of an appropriate model.

[0052] In this embodiment, a two-dimensional displacement adjustment mechanism is provided above the workbench 3. The two-dimensional displacement adjustment mechanism is connected to the laser marking device 6 and is used to adjust the height and horizontal displacement of the laser marking device 6. The main purpose of this design is to adjust the height between the laser marking device 6 and the workpiece on the lower station through the two-dimensional displacement adjustment mechanism, so as to ensure that the laser emission part of the laser marking device 6 is always directly above the lower station.

[0053] In a preferred embodiment, the two-dimensional displacement adjustment mechanism includes a vertically arranged height adjustment slide 31 and a horizontally arranged horizontal displacement adjustment slide 32. The horizontal displacement adjustment slide 32 is connected to the sliding component of the height adjustment slide 31. The laser marking device 6 is connected to the sliding component of the horizontal displacement adjustment slide 32. The barcode scanning detection device 5 is mounted above the workbench 3 via a height-adjustable bracket.

[0054] In the above implementation scheme, both the height adjustment slide 31 and the horizontal displacement adjustment slide 32 are commercially available manual adjustment slides, allowing for manual adjustment of the height and position of the laser marking device 6 before processing. The support includes a vertical fixed rod with a clamping block that can be adjusted vertically. A horizontal mounting rod is connected to the clamping block, and one end of the mounting rod is connected to the barcode scanning and detection device 5.

[0055] It should be noted that all electrical components in this embodiment are connected to the same control system to achieve automated and intelligent operation.
