Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a laser engraving testing device. Background Technology

[0002] Laser engraving is a surface treatment process similar to screen printing and pad printing, both of which print words or patterns on products. During laser engraving, the laser head engraves along the outer surface contour of the product. The shape and structure of the surface of the product being engraved is an important factor affecting the laser engraving process. Therefore, it is inevitable that some products will fail the laser engraving process, which requires identification and detection equipment for sorting.

[0003] An existing magnetic laser engraving pattern detection device (Announcement No.: CN219003788U) has at least the following drawbacks:

[0004] In the aforementioned patent, the movement of the magnet with laser-engraved pattern on the loading platform is controlled by a moving module, moving the magnet with the laser-engraved pattern into the recognition range of the visual recognition device. This replaces manual intervention in moving the magnet with the laser-engraved pattern, improves the detection speed, and avoids missed detections. However, the magnet needs to be manually placed before and after detection, which requires machine downtime and occupies equipment working time. The detection efficiency needs to be further improved. Therefore, it is necessary to propose a laser engraving detection device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a laser engraving inspection device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A laser engraving inspection device includes an identification platform with two magnets on its top surface and a PLC controller fixedly mounted on one side of the platform. It also includes a storage component disposed on the top surface of the identification platform for storing the magnets. The storage component comprises a fixed frame and a conveyor belt, both fixedly mounted on the top surface of the identification platform. A cylinder is fixedly fitted inside the fixed frame, and a push plate is fixedly mounted at one end of the cylinder's telescopic shaft. A movable frame is provided on the bottom surface of the conveyor belt, and a support plate is fixedly mounted thereon. A drive motor is fixedly mounted inside the support plate, and a threaded post is fixedly mounted on the top surface of the drive shaft of the drive motor. A threaded hole is formed on the bottom surface of the movable frame, and the threaded post is threadedly connected to the threaded hole. A partition shelf is provided on the top surface of the support plate.

[0008] As a further embodiment of this utility model, the bottom surface of the movable frame is provided with two limiting holes, and a fixing column is movably sleeved on the inner circular wall surface of the limiting hole. The top and bottom surfaces of the fixing column are respectively fixedly installed with the bottom surface of the conveyor belt and the top surface of the support plate.

[0009] As a further embodiment of this utility model, a main screw slide is fixedly installed on one side of the recognition platform, a secondary screw slide is fixedly installed on one side of the sliding table of the main screw slide, and a visual recognition camera is fixedly installed on one side of the sliding table of the secondary screw slide. The visual recognition camera, the main screw slide, the secondary screw slide, and the drive motor are all electrically connected to the PLC controller.

[0010] As a further embodiment of this utility model, a support frame is fixedly installed on the top surface of the conveyor belt, and a photoelectric sensor is fixedly sleeved inside the support frame. The photoelectric sensor is electrically connected to the PLC controller.

[0011] As a further embodiment of this utility model, a reinforcing rib is fixedly installed on the top surface of the sliding table of the main screw slide, and the reinforcing rib is fixedly installed with the secondary screw slide.

[0012] As a further embodiment of this utility model, a baffle is fixedly installed on one side of the recognition platform.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. By using a combination of an identification platform, magnets, conveyor belt, cylinder, push plate, support frame, photoelectric sensor, and main screw slide, the device can temporarily store magnets. The photoelectric sensor identifies the magnet's position, and the cylinder and push plate push the magnet into the shelf of the divider. The drive motor, threaded column, and threaded hole work together to lower the divider, automatically collecting defective magnets without manual removal for rework. Simultaneously, while storing magnets, another magnet on the right can be identified and tested, and a new magnet can be placed. This equipment eliminates the need to stop the machine before and after testing to place magnets, reducing operating time and improving testing efficiency, making it highly practical.

[0015] 2. The baffle can limit the shelf and prevent it from tipping over. The drive motor drives the threaded column to rotate and limits and supports the moving shelf through the limit hole and the fixed column, thereby lowering the moving shelf. As a result, the shelf drops one compartment for each magnet stored, allowing for the continued storage of magnets. Attached Figure Description

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Reference Figures 1-5 A laser engraving inspection device includes an identification platform 1, with two magnets 2 mounted on its top surface. A PLC controller is fixedly installed on one side of the identification platform 1. The device also includes a storage component, located on the top surface of the identification platform 1, for storing the magnets 2. The storage component includes a fixed frame 20 and a conveyor belt 3, both fixedly installed on the top surface of the identification platform 1. A cylinder 4 is fixedly fitted inside the fixed frame 20, and a push plate 5 is fixedly installed at one end of the telescopic shaft of the cylinder 4. A movable frame 13 is provided on the bottom surface of the conveyor belt 3. A support plate 12 is fixedly installed on the bottom surface of the conveyor belt 3. A drive motor 17 is fixedly installed inside the support plate 12. A threaded post 16 is fixedly installed on the top surface of the drive shaft of the drive motor 17. A threaded hole 18 is opened on the bottom surface of the moving frame 13. The threaded post 16 is threadedly connected to the threaded hole 18. A partition frame 11 is provided on the top surface of the support plate 12. Two limiting holes 14 are opened on the bottom surface of the moving frame 13. A fixed post 15 is movably sleeved on the inner circular wall of the limiting hole 14. The top and bottom surfaces of the fixed post 15 are fixedly installed to the bottom surface of the conveyor belt 3 and the top surface of the support plate 12, respectively.

[0026] In use, when a magnet fails inspection and needs to be recycled into the shelf 11 for secondary processing, the conveyor belt 3 is started to move the magnet 2. The displacement position of the magnet 2 is detected by the photoelectric sensor 7. After the magnet 2 moves beyond the detection range of the photoelectric sensor 7, the conveyor belt 3 is stopped, and the cylinder 4 is started to drive the push plate 5 to push the magnet 2 into the top surface of the shelf 11, thereby recycling the unqualified magnet 2. Conversely, if the magnet 2 is qualified, it can be placed into the shelf 11 for processing. If the magnet 2 is qualified, it is transported to the next process by the conveyor belt 3. The drive motor 17 is started to drive the threaded column 16 to rotate. The rotating threaded column 16 and the threaded hole 18 convert the rotational motion into linear motion. The moving frame 13 is limited and supported by the limiting hole 14 and the fixed column 15, which in turn lowers the moving frame 13. This causes the shelf 11 to descend one level for each magnet 2 stored, allowing for the continued storage of magnet 2.

[0027] In this embodiment, a main screw slide 8 is fixedly installed on one side of the recognition platform 1, a secondary screw slide 9 is fixedly installed on one side of the slide of the main screw slide 8, and a visual recognition camera 10 is fixedly installed on one side of the slide of the secondary screw slide 9. The visual recognition camera 10 is the same as that in the reference document. The visual recognition camera 10, the main screw slide 8, the secondary screw slide 9 and the drive motor 17 are all electrically connected to the PLC controller. A support frame 6 is fixedly installed on the top surface of the conveyor belt 3. A photoelectric sensor 7 is fixedly sleeved inside the support frame 6. The photoelectric sensor 7 is electrically connected to the PLC controller. A reinforcing rib 21 is fixedly installed on the top surface of the slide of the main screw slide 8. The reinforcing rib 21 is fixedly installed to the secondary screw slide 9. A baffle 19 is fixedly installed on one side of the recognition platform 1.

[0028] In use, when the user needs to inspect the magnet 2 via the identification platform 1, the magnet 2 is placed on the top left side of the conveyor belt 3, and then the visual recognition camera 10 inspects the magnet 2. The inspection method is the same as in the reference document. At the same time, the main screw slide 8 and the secondary screw slide 9 are used. The main screw slide 8 is started to drive the secondary screw slide 9 and the visual recognition camera 10 to move laterally, and the secondary screw slide 9 is started to drive the visual recognition camera 10 to move back and forth. Thus, the visual recognition camera 10 moves back and forth to inspect the magnet 2, ensuring the imaging and inspection effect of the magnet 2.

[0029] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0030] When a user needs to inspect magnet 2 using the designated recognition station 1, magnet 2 is placed on the top left side of conveyor belt 3. The magnet 2 is then inspected by the designated visual recognition camera 10, which operates in the same manner as in the reference document. Simultaneously, the main screw slide 8 and secondary screw slide 9 are activated. The main screw slide 8 moves the secondary screw slide 9 and the visual recognition camera 10 laterally, while the secondary screw slide 9 moves the visual recognition camera 10 back and forth. This back-and-forth movement of the visual recognition camera 10 allows it to inspect magnet 2. The measurement ensures the effectiveness of the imaging inspection of magnet 2. Then, when magnet 2 fails the inspection and needs to be recycled back into the shelf 11 for secondary processing, the conveyor belt 3 is started to move magnet 2. The photoelectric sensor 7 detects the displacement of magnet 2. Once magnet 2 moves beyond the detection range of the photoelectric sensor 7, the conveyor belt 3 stops, and the cylinder 4 drives the push plate 5 to move magnet 2 into the top surface of the shelf in the shelf 11, thus recycling the unqualified magnet 2. Conversely, qualified magnet 2 can be placed inside the shelf 11 as needed for convenient recycling. Magnet 2 is processed. If magnet 2 passes inspection, it is conveyed to the next process via conveyor belt 3. Simultaneously, drive motor 17 is activated to rotate threaded column 16. The rotating threaded column 16 and threaded hole 18 convert rotational motion into linear motion. Limiting holes 14 and fixing columns 15 provide limiting support for the moving frame 13, which in turn lowers the moving frame 13. This causes the shelf 11 to descend one level for each magnet 2 stored, allowing for continued storage of magnet 2. This achieves the combined effect of temporarily storing magnet 2, through photoelectric... Sensor 7 identifies the position of magnet 2 and pushes magnet 2 into the shelf of shelf 11 via cylinder 4 and push plate 5. Drive motor 17, threaded column 16, threaded hole 18, etc., lower shelf 11 to automatically collect unqualified magnet 2 without manual picking out for recycling and rework. At the same time, while storing magnet 2, another magnet 2 on the right can be identified and detected, and a new magnet 2 can be placed. This equipment does not need to stop to place magnets before and after detection, reducing the equipment working time and improving detection efficiency, making it quite practical.
