Description

Technical Field

[0001] This application relates to the field of laser marking technology, and in particular to an automatic marking device. Background Technology

[0002] During production, marking machines are frequently used to mark the casing of workpieces to identify the manufacturer, specifications, and other information. Marking machine is a broad concept, mainly divided into three types: pneumatic, laser, and electro-etching. Pneumatic marking: computer-controlled, the printing needle performs high-frequency impact motion under the action of compressed air, thus printing a mark of a certain depth on the workpiece. Marking characteristics: relatively large depth. Laser marking machines use a laser beam to create permanent marks on the surface of various materials. The marking effect is achieved by evaporating the surface material to expose the deeper material, thereby engraving exquisite patterns, trademarks, and text. Electro-etching mainly prints fixed trademarks, like a stamp, but it is inconvenient to change the printed content.

[0003] Currently, laser marking machines mostly rely on manual loading and unloading. Workers place the workpiece to be marked under the marking head, hold it in place, start the machine, and then manually remove the workpiece. This method is inefficient and labor-intensive, and therefore needs improvement. Utility Model Content

[0004] To facilitate marking of workpieces and improve production efficiency, this application provides an automatic marking device.

[0005] The automatic marking device provided in this application adopts the following technical solution:

[0006] An automatic marking device includes a frame, a conveyor belt, a vibratory feeder, a limiting component, a marking machine, and a sensor. The conveyor belt is rotatably connected to the frame. The vibratory feeder is located on one side of the frame and is used to vibrate and feed workpieces. The output end of the vibratory feeder is located above the input end of the conveyor belt. The limiting component is located above the conveyor belt and is used to limit the workpieces on the conveyor belt. The marking machine is located on the conveying path of the conveyor belt and is used to mark the workpieces. The sensor is located on the limiting component and below the marking machine, and is used to detect the position of the workpieces on the conveyor belt.

[0007] By employing the above technical solution, a vibratory feeder feeds the workpieces using vibration, causing them to fall neatly onto the conveyor belt in a specific orientation. As the conveyor belt continues to transport the workpiece, when it moves directly beneath the marking machine, a sensor detects its presence and sends a signal back to the conveyor belt, causing it to pause. The marking machine then restarts to mark the workpiece. After marking, the conveyor belt resumes operation, allowing the marked workpiece to be unloaded. The entire process is highly automated, facilitating convenient workpiece marking, improving production efficiency, and reducing labor intensity.

[0008] Preferably, the limiting component includes a first limiting plate and a second limiting plate, the first limiting plate and the second limiting plate are arranged opposite to each other and form a limiting groove, the limiting groove is used to limit the workpiece, and the sensor is disposed on the second limiting plate.

[0009] By adopting the above technical solution, the workpiece is blocked by the first limiting plate and the second limiting plate during the conveying process, so that the workpiece moves in a straight line.

[0010] Preferably, the distance between the first limiting plate and the second limiting plate is adjustable, and the second limiting plate moves in a direction that is closer to or farther from the first limiting plate.

[0011] By adopting the above technical solution, the distance between the first limiting plate and the second limiting plate can be adjusted, which facilitates the limiting of workpieces of different sizes.

[0012] Preferably, the assembly further includes a fixing block, a connecting rod, and a fastener. The fixing block is mounted on the frame. One end of the connecting rod is connected to the second limiting plate, and the other end passes through the fixing block. The fixing block has an installation hole, and the fastener passes through the installation hole and locks the connecting rod onto the fixing block.

[0013] By adopting the above technical solution, when it is necessary to adjust the width of the limiting groove, the fasteners can be loosened first, and then an external force can be applied to the connecting rod to control the second limiting plate to move closer to or further away from the first limiting plate, thereby changing the spacing.

[0014] Preferably, the marking machine also includes a driving component and a positioning component. The driving component is located below the marking machine, and the positioning component is connected to the driving component and is used to press against the workpiece. The driving component is used to control the movement of the positioning component.

[0015] By adopting the above technical solution, when the workpiece moves directly below the marking machine, the driving component can be activated. The driving component controls the positioning component to press against the workpiece to fix it in place, so that the marking machine can accurately mark on the workpiece.

[0016] Preferably, it also includes a collection box, which has an opening and is located below the output end of the conveyor belt. The collection box is used to receive the marked workpiece.

[0017] By adopting the above technical solution, the marked workpieces can fall into the collection box for centralized storage.

[0018] Preferably, it also includes a noise-proof box, the vibrating plate is disposed inside the noise-proof box, and the inner wall of the noise-proof box is provided with sound-absorbing cotton.

[0019] By adopting the above technical solution, the vibratory feeder will generate a lot of noise during operation. The noise reduction box can isolate a certain amount of noise and reduce the impact of noise on the surrounding staff.

[0020] Preferably, the noise-proof box has an opening, and a cover plate is rotatably connected to the opening of the noise-proof box, the cover plate being used to seal the opening.

[0021] By adopting the above technical solution, the cover plate is placed on the noise-proof box to achieve the sealing of the noise-proof box. After all the workpieces on the vibratory feeder are loaded, the workers open the cover plate and add more workpieces to the vibratory feeder.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] (1) By setting up a conveyor belt, vibratory feeder, limit components, marking machine, and sensors, the vibratory feeder vibrates and feeds the workpiece, which is then conveyed by the conveyor belt. When the workpiece moves directly under the marking machine, the sensor detects its presence and sends a signal back to the conveyor belt, causing it to pause conveying. Then, the marking machine starts to mark the workpiece. The entire process is highly automated, making it convenient to mark workpieces, improving production efficiency, and reducing the labor intensity of personnel.

[0024] (2) By setting fixed blocks, connecting rods and fasteners, it is convenient to limit the workpieces of different sizes and improve the practicality.

[0025] (3) By setting up noise-proof boxes, noise-proof boxes can isolate a certain amount of noise, reduce the impact of noise on surrounding staff, and protect the health of workers. Attached Figure Description

[0034] This application discloses an automatic marking device. (Refer to...) Figure 1 and Figure 2The automatic marking device includes a frame 1, a conveyor belt 2, a vibratory feeder 3, a limiting assembly 4, a marking machine 5, and a sensor 6. The frame 1 serves as a carrier, and the conveyor belt 2 is rotatably connected to the frame 1. The vibratory feeder 3 is located on one side of the frame 1 and is used to vibrate and feed workpieces. The output end of the vibratory feeder 3 is located above the input end of the conveyor belt 2, and the conveyor belt 2 is used to transport the workpieces output from the vibratory feeder 3. The limiting assembly 4 is installed above the conveyor belt 2 and is used to limit the workpieces on the conveyor belt 2. The marking machine 5 is located on the conveying path of the conveyor belt 2 and is used to mark the workpieces. In this embodiment, the marking machine 5 is a laser marking machine. The sensor 6 is installed on the limiting assembly 4 and is located below the marking machine 5. In this embodiment, the sensor 6 is a positioning sensor 6, which is used to detect the position of the workpieces on the conveyor belt 2.

[0035] During production, the vibratory feeder 3 vibrates and feeds the workpieces, which then fall neatly onto the conveyor belt 2 in a specific orientation. As the conveyor belt 2 continues to transport the workpiece, when it moves directly below the marking machine 5, the sensor 6 detects its presence and sends a signal back to the conveyor belt 2, causing it to pause. The marking machine 5 then starts to mark the workpiece. After marking, the conveyor belt 2 resumes operation, allowing the marked workpiece to be unloaded. The entire process is highly automated, facilitating convenient workpiece marking, improving production efficiency, and reducing labor intensity.

[0036] Specifically, the limiting component 4 includes a first limiting plate 41 and a second limiting plate 42. The first limiting plate 41 and the second limiting plate 42 are parallel to each other and are arranged along the conveying direction of the conveyor belt 2. The first limiting plate 41 and the second limiting plate 42 are arranged opposite to each other and form a limiting groove 16. The limiting groove 16 is used to limit the workpiece on the conveyor belt 2 so that the workpiece moves in a straight line. The sensor 6 is installed on the second limiting plate 42.

[0037] In this embodiment, the horizontal distance between the first limiting plate 41 and the second limiting plate 42 is adjustable. The second limiting plate 42 moves towards or away from the first limiting plate 41 to limit workpieces of different sizes, improving practicality. A fixing block 7 is fixedly connected to the frame 1, and a connecting rod 8 is fixedly connected to the second limiting plate 42. The connecting rod 8 is horizontally positioned, with one end of the connecting rod 8 away from the second limiting plate 42 passing through the fixing block 7. A mounting hole is provided through the fixing block 7, and the connecting rod 8 is locked to the fixing block 7 by a fastener 9. The fastener 9 is a fastening bolt or a fastening stud, screwed into the mounting hole, with its end abutting against the connecting rod 8. As shown in the figure, in this embodiment, there are three connecting rods 8 on the second limiting plate 42, and each connecting rod 8 is parallel to the others.

[0038] When it is necessary to adjust the width of the limiting groove 16, the fastener 9 can be loosened first, and then an external force can be applied to the connecting rod 8 to control the second limiting plate 42 to move closer to or further away from the first limiting plate 41, thereby changing the spacing. When the position is adjusted to a suitable position, the fastener 9 can be tightened onto the connecting rod 8 to fix the position of the connecting rod 8.

[0039] In some embodiments, a drive unit 10 and a positioning unit 11 are also mounted on the frame 1. The drive unit 10 is located below the marking machine 5, and the positioning unit 11 is connected to the drive unit 10 and used to press against the workpiece. The drive unit 10 controls the linear movement of the positioning unit 11. The drive unit 10 is a linear cylinder or an electric push rod, and the positioning unit 11 is plate-shaped or block-shaped, and is fixedly connected to the piston rod of the linear cylinder. When the workpiece moves directly below the marking machine 5, the drive unit 10 can be activated, and the drive unit 10 controls the positioning unit 11 to press against the workpiece to fix the workpiece, so that the marking machine 5 can accurately mark on the workpiece.

[0040] A noise-damping box 12 is installed next to the frame 1. The noise-damping box 12 has an opening and an internal cavity. Sound-absorbing cotton 13 is fixedly connected inside the noise-damping box 12, and the vibrating plate 3 is placed inside the noise-damping box 12. A cover plate 14 is rotatably connected to the opening of the noise-damping box 12, which is used to seal the opening of the noise-damping box 12, thus achieving the closure of the noise-damping box 12. Since the vibrating plate 3 will generate considerable noise during operation, by adding the noise-damping box 12, the noise-damping box 12 can absorb and isolate a certain amount of noise, reducing the impact of noise on surrounding workers.

[0041] In addition, a collection box 15 is placed below the output end of the conveyor belt 2. The collection box 15 is rectangular and has an opening. The collection box 15 is used to collect the marked workpieces, realize the centralized storage of workpieces, and facilitate the subsequent processing of workpieces.

[0042] The implementation principle of the automatic marking device in this embodiment is as follows: A vibratory feeder 3 vibrates and feeds the workpiece, which then falls neatly onto the conveyor belt 2 in a specific orientation. As the conveyor belt 2 continues to transport the workpiece, when it moves directly below the marking machine 5, the sensor 6 detects its presence and sends a signal back to the conveyor belt 2, causing it to pause. Then, the drive unit 10 is activated, controlling the positioning unit 11 to press firmly onto the workpiece. The marking machine 5 is then started to mark the workpiece. After marking, the conveyor belt 2 continues to run, causing the workpiece to fall into the collection box 15, completing the unloading process. The entire process is highly automated, facilitating workpiece marking, improving production efficiency, and reducing labor intensity.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
