Description

Technical Field

[0001] This utility model relates to the field of laser marking machine technology, and in particular to a laser marking machine. Background Technology

[0002] Laser marking machines are devices that use laser beams to permanently mark the surface of materials. By evaporating the surface material to expose the deeper material, they can achieve fine engraving of patterns, text, or trademarks. They are widely used in high-precision fields such as electronic components, hardware products, and medical devices.

[0003] Chinese utility model patent CN222588411U discloses a laser marking machine for producing power supply switches. This device transports the power supply switch to be laser-marked to a laser marking mechanism via a conveyor belt. A stop block blocks the power supply switch, and two push plates simultaneously rise to lift the switch off the conveyor belt. The laser marking mechanism then starts to laser-mark the power supply switch. Simultaneously, a dust filtration mechanism collects and filters the dust generated during the laser marking process. Regarding the aforementioned technology, the inventors believe the following defects exist:

[0004] In actual use, this device makes it difficult to ensure the accuracy of the product's position when it is placed on the surface of the conveyor belt. This can cause the product to deviate in position when it moves under the laser marking machine, which can affect the normal marking of the product and reduce processing efficiency. Therefore, we provide a laser marking machine. Utility Model Content

[0005] To address the issue in the aforementioned background technology where the precise placement of the product to be marked is difficult to guarantee, thus affecting the normal marking process, this utility model provides a laser marking machine.

[0006] This utility model is achieved using the following technical solution: a laser marking machine, including a base and a pushing assembly. A column is fixedly connected to the base, an infrared sensor is installed on the column, a frame is installed on the column, a laser marking device is fixedly connected to the frame, a conveyor is fixedly connected to the base, a dust collection box is also fixedly connected to the base, an exhaust pipe is fixedly connected to one side of the dust collection box, an exhaust fan is fixedly connected inside the exhaust pipe, a filter is fixedly connected inside the dust collection box, and dust suction hoods are fixedly connected to both sides of the laser marking device. A connecting hose is fixedly connected between the dust suction hoods and the dust collection box.

[0007] The pushing assembly includes two sets of push plates movably disposed on one side of the top of the conveyor. A bracket is fixedly connected to the top of the machine base, and a motor is fixedly connected to the bracket. A turntable is coaxially fixedly connected to the end of the rotor of the motor. A column is disposed outside the turntable, and a rectangular frame is movably disposed outside the column. A connecting rod is fixedly connected to the bottom of the rectangular frame, and a connecting rod is hinged to the push plate through a hinge.

[0008] As a further improvement to the above solution, two sets of striking balls are symmetrically arranged on one side of the filter screen. A crossbar is fixedly connected to the striking ball, and the end of the crossbar extends movably to the outside of the dust collection box. The ends of the two sets of crossbars are fixedly connected to the same iron connecting plate. A spring is sleeved on the outside of the crossbar. A fixing rod is fixedly connected to one side of the push plate. Two sets of stop bars are fixedly connected to the bottom of the fixing rod. A stop block is fixedly connected to the top of the iron connecting plate. A magnet is fixedly connected to the top of the machine base through a fixing frame.

[0009] As a further improvement to the above solution, a slide rail is fixedly connected to the column, and an electric slide table is slidably connected to the outside of the slide rail and the electric slide table is fixedly connected to the frame.

[0010] As a further improvement to the above solution, two sets of guide rods are fixedly connected to one side of the top of the conveyor, and two sets of guide blocks are symmetrically fixedly connected to the top of the push plate, with the guide blocks slidably connected to the guide rods on the same side.

[0011] As a further improvement to the above solution, the column is fixedly connected to the outside of the turntable near the edge, and a limit plate is fixedly connected to the end of the column.

[0012] As a further improvement to the above solution, a guide frame is fixedly connected to the bracket, and the guide frame is slidably connected to the connecting rod.

[0013] As a further improvement to the above solution, the two ends of the spring are fixedly connected to the dust collection box and the iron connecting plate, respectively.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model uses a motor to drive a turntable to rotate, which in turn drives the column rod to make a circular motion. Utilizing the movable cooperation between the column rod and the rectangular frame, and the sliding cooperation between the connecting rod and the guide frame, the connecting rod can be driven to move vertically. With the sliding cooperation between the guide block and the guide rod, and the hinged cooperation between the connecting rod and the push plate and the connecting rod, two sets of push plates can be driven to move simultaneously and regularly towards and away from each other. This automatically pushes the product on the conveyor surface towards the center position, thus preventing positional deviation when the product moves to the area below the laser marking device. It is highly practical.

[0016] 2. In this invention, as the push plate moves towards the center of the conveyor surface, it also drives the fixed rod to move together. Utilizing the blocking effect of the stop block on the outer stop rod, and the sliding cooperation between the crossbar and the dust collection box, the fixed rod pulls the iron connecting plate along with it, causing the striking ball to move away from the filter screen. At this time, the spring is stretched. When the push plate moves to its maximum distance, the iron connecting plate will be attracted to the magnet. When the push plate moves outward from the center of the conveyor surface, it pushes the fixed rod to move together. When the inner stop rod contacts the stop block, as the fixed rod continues to move, the iron connecting plate separates from the magnet. Utilizing the spring's own rebound effect, the striking ball automatically resets and impacts the stainless steel filter screen. The filter screen vibrates, shaking off the attached particles to prevent clogging, thus ensuring a good suction effect for smoke and dust, further improving the practicality of the device.

A bracket is fixedly connected to the top of the base 1, and a motor is fixedly connected to the bracket. A turntable 102 is coaxially fixedly connected to the end of the motor rotor. A column 103 is provided outside the turntable 102, and a rectangular frame 104 is movably mounted outside the column 103. A connecting rod 105 is fixedly connected to the bottom of the rectangular frame 104. A connecting rod 105 is hinged to the push plate 101 via a hinge. 06. Two sets of guide rods 10 are fixedly connected to one side of the top of the conveyor 5. Two sets of guide blocks are symmetrically fixedly connected to the top of the push plate 101, and the guide blocks are slidably connected to the guide rods 10 on the same side, which can play a certain guiding role in the movement of the push plate 101. The column rod 103 is fixedly connected to the outside of the turntable 102 near the edge. The end of the column rod 103 is fixedly connected to the limit plate. The bracket is fixedly connected to the guide frame, and the guide frame is slidably connected to the connecting rod 105, which can play a certain guiding role in the vertical movement of the connecting rod 105.

[0027] Two sets of striking balls 201 are symmetrically arranged on one side of the filter screen 8. A crossbar 202 is fixedly connected to the striking ball 201, and the end of the crossbar 202 extends movably to the outside of the dust collection box 6. A sealing ring is provided at the movable connection between the crossbar 202 and the dust collection box 6 to ensure sealing. The ends of the two sets of crossbars 202 are fixedly connected to the same iron connecting plate 203. A spring 204 is sleeved on the outside of the crossbar 202. The two ends of the spring 204 are fixedly connected to the dust collection box 6 and the iron connecting plate 203, respectively. A fixing rod 205 is fixedly connected to the push plate 101 on one side. Two sets of stop bars 206 are fixedly connected to the bottom of the fixing rod 205. A stop block 207 is fixedly connected to the top of the iron connecting plate 203. A magnet 208 is fixedly connected to the top of the base 1 through a fixing frame.

[0028] The implementation principle of a laser marking machine in this application embodiment is as follows: The product to be marked is placed on the conveyor surface of the conveyor 5. The motor and the conveyor 5 are started. The motor drives the turntable 102 to rotate, so that the turntable 102 can drive the column rod 103 to make a circular motion. Utilizing the movable cooperation between the column rod 103 and the rectangular frame 104, and the sliding cooperation between the connecting rod 105 and the guide frame, the connecting rod 105 can be driven to move vertically. Under the sliding cooperation between the guide block and the guide rod 10, and the hinged cooperation between the connecting rod 105 and the push plate 101 and the connecting rod 106, the two sets of push plates 101 can be driven to move simultaneously and regularly towards and away from each other, thereby... The conveyor 5 can automatically push the product on its conveyor surface to the center position, thus preventing positional deviation when it moves below the laser marking device 4. The distance the pusher 101 moves is matched to the product size, so it will not cause excessive compression to the product. The conveyor 5 can transport the product. When the product after position correction passes the infrared sensor, the conveyor 5 will automatically stop transporting for a period of time. At this time, the laser marking device 4 can mark the product. Then the conveyor 5 continues to operate and transport the marked product. The working principle of the infrared sensor is consistent with that in the comparison document, so it will not be elaborated on here. During the process, the air inside the dust collection box 6 is exhausted by the exhaust fan to create negative pressure, allowing the fumes generated during the marking process to be sucked in through the dust suction hood 9. This prevents fumes from polluting the working environment and harming the health of the workers. The particles in the fumes are intercepted by the filter screen 8 and collected in the dust collection box 6. As the push plate 101 moves towards the center of the conveyor surface of the conveyor 5, it also moves the fixed rod 205. The blocking effect of the stop block 207 on the outer stop rod 206 and the sliding cooperation between the crossbar 202 and the dust collection box 6 allow the fixed rod 205 to pull the iron connecting plate 203 to move together when it moves, thereby moving the striking ball 201 away from the filter screen 8. At this time, the spring 204 will be stretched. When the push plate 101 moves to the maximum distance, the iron connecting plate 203 will be attracted to the magnet 208. When the push plate 101 moves outward from the center of the conveyor surface of the conveyor 5, it can push the fixed rod 205 to move together. When the inner stop rod 206 contacts the stop block 207, as the fixed rod 205 continues to move, the iron connecting plate 203 will separate from the magnet block 208. Utilizing the rebound effect of the spring 204, the striking ball 201 will automatically reset and strike the stainless steel filter screen 8. At this time, the filter screen 8 will vibrate to shake off the attached particles to prevent clogging of the filter screen 8, thereby ensuring a good suction effect for smoke and dust.
