Description

Technical Field

[0001] This invention belongs to the field of combined machine tool technology, and in particular relates to a multi-station laser engraving device for processing patterns on the surface of carbonized building blocks. Background Technology

[0002] Carbonized building blocks are wooden blocks made from natural solid wood through a high-temperature, oxygen-free carbonization process. They are mainly used for children's toys, kindergarten teaching aids, and outdoor construction. After the carbonized building blocks are produced, patterns are usually carved onto their surface. The carving process involves a combination of block positioning, pattern carving, and pattern groove cleaning, which requires the use of multi-station combination machining centers for carving.

[0003] In existing technologies, traditional engraving machine tools maintain the engraving surface of carbonized building blocks facing upwards throughout the entire engraving process, relying solely on a suction device to collect dust during the engraving process. This lack of cleaning of the engraved grooves after the pattern is completed results in residual debris within these grooves, increasing the workload for subsequent cleaning and consequently impacting the overall engraving efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-station laser engraving device for processing patterns on the surface of carbonized building blocks. Through the specific structural design of the engraving mechanism, chip collection tube assembly, power transmission component, rotation component, limiting component, negative pressure positioning component, and belt conveyor system, it solves the problem that traditional engraving machine tools lack cleaning processing of pattern grooves after pattern engraving, resulting in residual debris in the pattern grooves of the carbonized building blocks after engraving, which in turn affects the engraving efficiency of carbonized building blocks.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: The present invention is a multi-station laser engraving equipment for processing patterns on the surface of carbonized building blocks, including a positioning station, an engraving station and a pattern cleaning station arranged in sequence. An engraving mechanism is installed at the engraving station, and a chip collection tube group is provided between the engraving station and the pattern cleaning station. The chip collection tube group is configured to collect the dust generated during the engraving and pattern cleaning processes.

[0006] The positioning station is equipped with a combined processing and transmission mechanism, which includes a transmission power component configured to reciprocate between the positioning station, the engraving station, and the pattern cleaning station. This mechanism includes a hollow, sealed enclosure with an arc-shaped structure; a rotating component located within the hollow enclosure with a limiting component mounted on its top, the limiting component being configured to support the carbonized building block at the bottom and limit its circumference; and a negative pressure positioning component located inside the rotating component, configured to adsorb the carbonized building block under negative pressure and position it within the limiting component. The rotating component at the pattern cleaning station rotates 180° to place the engraved carbonized building block within the hollow enclosure. The bottom outlet of the hollow enclosure is connected to a chip collection pipe assembly, which blows and sucks up the pattern on the surface of the carbonized building block.

[0007] The present invention is further configured to include a combined processing frame, a hydraulic cylinder being mounted on the rear side of the combined processing frame via a fixed bracket, a horizontal guide rail being fixedly provided on the front side of the combined processing frame, and a belt conveyor system located at the front end of the positioning station being mounted on the combined processing frame.

[0008] The present invention is further configured such that a guide assembly located above the belt conveyor system is installed on the top of the combined processing frame. The guide assembly includes a power unit and two oppositely arranged conveyor guide plates. The power unit is configured to adjust the horizontal distance between the two conveyor guide plates. The gap between the bottom of the conveyor guide plate and the top of the belt conveyor system is 2.0-3.0 mm.

[0009] The present invention is further configured such that a support frame is installed on the top of the combined processing frame, a mounting plate is connected to the cylinder output end installed on the top of the support frame, and a laser engraver is provided at the bottom of the mounting plate. The engraving mechanism consists of a support frame, a cylinder, a mounting plate and a laser engraver.

[0010] The invention is further configured such that an arc-shaped chip collection cover fixed to the bottom of a horizontal guide rail is provided at the pattern cleaning station, a ventilation main is connected to the bottom of the arc-shaped chip collection cover, a hollow collection ring is sleeved on the outside of the support frame, a suction port is provided on the inner wall of the hollow collection ring, and a ventilation branch pipe is connected between the hollow collection ring and the ventilation main. The chip collection pipe assembly consists of a hollow collection ring, a ventilation branch pipe, a ventilation main and an arc-shaped chip collection cover.

[0011] The invention is further configured such that a limiting seat and a support plate are fixed on the periphery of the hollow sealed cover, the limiting seat is slidably fitted inside the horizontal guide rail, the support plate is connected to the movable end of the hydraulic cylinder, an electric push rod is connected to one side of the hollow sealed cover through a mounting bracket, and a drive motor is connected to the other side of the hollow sealed cover through a mounting bracket.

[0012] The present invention is further configured such that the rotating component includes an arc-shaped mounting ring rotatably fitted on the inner wall of the hollow sealed cover, and a U-shaped frame connected to the output shaft of the drive motor is fixed inside the arc-shaped mounting ring. The U-shaped frame has guide channels composed of inclined grooves and straight grooves on its two inner side walls, and a moving channel is provided at the bottom of the U-shaped frame.

[0013] The present invention is further configured such that the limiting component includes a block carrier fixedly installed on the top of the arc-shaped mounting ring, the top of the block carrier is provided with a block limiting cavity, the bottom of the block carrier is provided with a negative pressure port communicating with the block limiting cavity, and a pressure sensor is installed inside the block limiting cavity.

[0014] The present invention is further configured such that the negative pressure positioning component includes a support one and a support two disposed on the inner and outer sides of the U-shaped frame. Support one passes through the moving channel and is fixedly connected to support two. Support one is rotatably connected to the movable end of the electric push rod through a bearing. A power supply and a negative pressure generator are respectively installed at the bottom of the inner side of support two. A negative pressure suction tube is installed on the negative pressure generator.

[0015] The present invention is further configured such that a lifting frame is longitudinally slidably provided on the support, and spherical guide rods that cooperate with the guide channel are fixed on both sides of the lifting frame. An air guide pipe is fixedly installed inside the lifting frame, and the air guide pipe is sealed and sleeved on the negative pressure suction pipe. A negative pressure suction cup is connected to the top of the air guide pipe.

[0016] The present invention has the following beneficial effects: 1. The present invention, through the sequential setting of a positioning station, an engraving station and a pattern cleaning station, allows carbonized building blocks to be positioned at the positioning station and then transferred to the engraving station. The engraving mechanism is used to engrave patterns on the carbonized building blocks. After the pattern engraving is completed, the carbonized building blocks are transferred to the pattern cleaning station, where the pattern grooves are cleaned through the chip collection tube assembly. By designing a combined processing machine tool consisting of a positioning station, an engraving station and a pattern cleaning station, the combined processing of carbonized building blocks is realized, thereby improving the combined processing efficiency of carbonized building blocks.

[0017] 2. This invention features a hollow collection ring fitted onto the outside of the support frame. The inner wall of the hollow collection ring has a suction port, and a ventilation branch pipe connects the hollow collection ring to the main ventilation pipe. The chip collection pipe assembly consists of the hollow collection ring, the ventilation branch pipe, the main ventilation pipe, and the arc-shaped chip collection hood. The chip collection pipe assembly not only collects dust at the carving station but also collects debris at the pattern cleaning station, avoiding the need for a separate pattern groove cleaning process, thereby improving the overall efficiency of carbonized building block pattern carving.

[0018] 3. In this invention, the carbonized building block is conveyed to the building block limiting cavity via a belt conveyor system. The electric push rod pushes the negative pressure positioning component to move towards the drive motor. During this process, the spherical guide rod slides along the inclined groove of the guide channel into the straight groove. At this time, the top of the negative pressure suction cup is just in contact with the bottom of the carbonized building block. The negative pressure generator controls the negative pressure suction cup to achieve the adsorption and fixation of the bottom of the carbonized building block. After the negative pressure suction cup adsorbs and fixes the carbonized building block, it drives it to move synchronously until the pressure sensor detects the set pressure value. The carbonized building block is completely and tightly fitted in the building block limiting cavity to complete the positioning, effectively avoiding the deviation of the carbonized building block during movement and carving, thereby ensuring the carving quality of the carbonized building block.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1, please refer to Figures 1-9 The present invention is a multi-station laser engraving device for processing patterns on the surface of carbonized building blocks, including a positioning station, an engraving station and a pattern cleaning station arranged in sequence. An engraving mechanism 1 is installed at the engraving station, and a chip collection tube group 2 is provided between the engraving station and the pattern cleaning station. The chip collection tube group 2 is configured to collect the dust generated during the engraving and pattern cleaning processes.

[0033] The positioning station is equipped with a combined processing and transmission mechanism 3, which includes a transmission power component 4, a rotation component 6, and a negative pressure positioning component 9. The transmission power component 4 is configured to reciprocate between the positioning station, the engraving station, and the pattern cleaning station. The transmission power component 4 includes a hollow sealed cover 5 with an arc-shaped structure. The rotation component 6 is located inside the hollow sealed cover 5 and a limit component 7 is installed on its top. The limit component 7 is configured to support the bottom and limit the circumference of the carbonized building block 8.

[0034] The negative pressure positioning component 9 is located inside the rotating component 6 and is configured to adsorb the carbonized building block 8 under negative pressure and achieve positioning within the limiting component 7; by rotating the rotating component 6 at the pattern cleaning station by 180°, the carbonized building block 8 that has been engraved is placed inside the hollow sealed cover 5. The bottom outlet of the hollow sealed cover 5 is connected to the chip collection pipe group 2, and the chip collection pipe group 2 blows and sucks the pattern on the surface of the carbonized building block 8.

[0035] In this embodiment of the invention, such as Figure 2 and Figure 3 As shown, the present invention also includes a combined processing frame 10. A hydraulic cylinder 11 is mounted on the rear side of the combined processing frame 10 via a fixed frame. A horizontal guide rail 12 is fixedly provided on the front side of the combined processing frame 10. A belt conveyor system 13 located at the front end of the positioning station is mounted on the combined processing frame 10. It should be noted that the belt conveyor system 13 is a commonly used conveyor belt system in the prior art, so it will not be described in detail.

[0036] Furthermore, a guide assembly 14 is installed on the top of the combined processing frame 10, located above the belt conveyor system 13. The guide assembly 14 includes a power unit and two oppositely arranged conveyor guide plates 15. The power unit is configured to adjust the horizontal distance between the two conveyor guide plates 15. The gap between the bottom of the conveyor guide plate 15 and the top of the belt conveyor system 13 is 2.0-3.0 mm. It should be noted that this power unit is a conventional setting in the prior art. For example, the two conveyor guide plates 15 are fitted between a slide rod and a lead screw. The slide rod limits the two conveyor guide plates 15 on it, and the lead screw is driven by a motor to make the two conveyor guide plates 15 move closer or further apart.

[0037] In this embodiment of the invention, such as Figure 3 As shown, a support frame 16 is mounted on the top of the combined processing frame 10. The output end of the cylinder 17 mounted on the top of the support frame 16 is connected to a mounting plate 18. A laser engraver is located at the bottom of the mounting plate 18. The engraving mechanism 1 consists of the support frame 16, the cylinder 17, the mounting plate 18, and the laser engraver. It should be noted that this laser engraver is a commonly used automatic laser engraving device in the prior art. The control process of its engraving pattern is set by the control system. Since this is prior art, the specific structure and operation mode of the laser engraver will not be described in detail. When the carbonized building block 8 is transported to the engraving station (i.e., directly below the laser engraver), the mounting plate 18 is controlled by the cylinder 17 to move the laser engraver downward to the set position. Then, the laser engraver is started to engrave the pattern on the top surface of the carbonized building block 8 according to the system setting program. After the pattern engraving is completed, the laser engraver is moved upward and reset by the cylinder 17 and the mounting plate 18.

[0038] Example 2, based on Example 1, such as Figure 2 and Figure 3As shown, an arc-shaped chip collection cover 19 is fixed to the bottom of a horizontal guide rail 12 at the pattern cleaning station. The horizontal guide rail 12 provides stable support for the arc-shaped chip collection cover 19. A ventilation main 20 is connected to the bottom of the arc-shaped chip collection cover 19 (this ventilation main 20 is connected to a U-shaped air pipe; one end of the U-shaped air pipe is connected to an exhaust fan, which is used to draw the fumes generated during the engraving process into the processing equipment; the other end of the U-shaped air pipe is connected to an air supply fan; solenoid valves are installed on both sides of the ventilation main 20 on the U-shaped air pipe, and only one of the two solenoid valves is opened at a time). The above structure is existing technology, therefore... (Not shown in the figure) A hollow collection ring 21 is fitted on the outer side of the support frame 16. The inner wall of the hollow collection ring 21 is provided with a suction port (not shown in the figure). A ventilation branch pipe 22 is provided between the hollow collection ring 21 and the ventilation main pipe 20. The chip collection pipe group 2 consists of the hollow collection ring 21, the ventilation branch pipe 22, the ventilation main pipe 20 and the arc-shaped chip collection cover 19. The chip collection pipe group 2 can not only collect the smoke and dust at the carving station, but also collect the debris at the pattern cleaning station, avoiding the need to add a separate pattern groove cleaning process later, thereby improving the overall efficiency of the carbonized building block 8 pattern carving process.

[0039] In this embodiment of the invention, such as Figure 4 and Figure 5 As shown, the hollow sealed cover 5 has a limiting seat 23 and a support plate 24 fixed on its surrounding sides. The limiting seat 23 is slidably fitted inside the horizontal guide rail 12, and the support plate 24 is connected to the movable end of the hydraulic cylinder 11. The above structural design can realize the horizontal reciprocating motion of the entire combined processing and transmission mechanism 3. One side of the hollow sealed cover 5 is connected to an electric push rod 25 through a mounting bracket, and the other side of the hollow sealed cover 5 is connected to a drive motor 26 through a mounting bracket. During the engraving process, the power supply method of the electric push rod 25 and the drive motor 26 is a conventional setting in the prior art. For example, the wires connected to the electric push rod 25 and the drive motor 26 can be set to a certain length to ensure stable power supply and electrical control during the movement of the combined processing and transmission mechanism 3. Of course, it is also possible to install a power supply unit on the hollow sealed cover 5. The specific power supply and control method depends on the specific situation.

[0040] In this embodiment of the invention, such as Figure 8 As shown, the rotating assembly 6 includes an arc-shaped mounting ring 27 that is rotatably fitted on the inner wall of the hollow sealed cover 5. A U-shaped frame 28 connected to the output shaft of the drive motor 26 is fixed inside the arc-shaped mounting ring 27. The U-shaped frame 28 has guide channels 29 composed of inclined grooves and straight grooves on its two inner side walls. The bottom of the U-shaped frame 28 has a moving channel 30.

[0041] Furthermore, the limiting component 7 includes a block carrier 31 fixedly installed on the top of the arc-shaped mounting ring 27. The block carrier 31 is detachably installed on the top of the arc-shaped mounting ring 27 using fasteners, so as to replace the corresponding model of the limiting component 7 according to production needs. The top of the block carrier 31 is provided with a block limiting cavity 32, and the bottom of the block carrier 31 is provided with a negative pressure port 33 communicating with the block limiting cavity 32. A pressure sensor 34 is installed inside the block limiting cavity 32.

[0042] Example 3, based on Examples 1 and 2, as follows: Figure 7 and Figure 9 As shown, the negative pressure positioning assembly 9 includes a first support 35 and a second support 36 located on the inner and outer sides of the U-shaped frame 28. The first support 35 passes through the moving channel 30 and is fixedly connected to the second support 36. The first support 35 is rotatably connected to the movable end of the electric push rod 25 through a bearing. A power supply 37 and a negative pressure generator 38 are respectively installed at the bottom of the second support 36 (both the power supply 37 and the negative pressure generator 38 are existing technologies, so they will not be described in detail here). A negative pressure suction tube 39 is installed on the negative pressure generator 38, and the pressure sensor 34 is powered by the power supply 37.

[0043] Furthermore, a lifting frame 40 is longitudinally slidably provided on the support 35. Specifically, a limiting sleeve is provided on the back of the lifting frame 40, and a vertically arranged T-shaped guide seat is fixed on the surface of the support 35. The limiting sleeve is slidably fitted on the T-shaped guide seat. Spherical guide rods 41 that cooperate with the guide channel 29 are fixed on both sides of the lifting frame 40. Lubricant is coated on the inner surface of the guide channel 29. An air guide pipe 42 is fixedly installed inside the lifting frame 40. The air guide pipe 42 is sealed on the negative pressure suction pipe 39, and a negative pressure suction cup 43 is connected to the top of the air guide pipe 42.

[0044] like Figure 1As shown in (A1), the initial combined processing and transmission mechanism 3 is in the positioning station, with the limiting component 7 facing upwards. The carbonized building block 8 to be carved is placed on the belt conveyor system 13 between the conveyor guide plates 15. The belt conveyor system 13 transports the carbonized building block 8 to the building block limiting cavity 32 (during the conveyor system 13 transports the carbonized building block 8, the conveyor guide plates 15 on both sides ensure that the carbonized building block 8 accurately enters the building block limiting cavity 32). Then, the electric push rod 25 pushes the negative pressure positioning component 9 to the drive motor 2. The movement is 6-way (the negative pressure generator 38 is activated simultaneously during the movement). During this process, the spherical guide rod 41 slides along the inclined groove of the guide channel 29 into the straight groove. At this time, the top of the negative pressure suction cup 43 is just attached to the bottom of the carbonized building block 8. The negative pressure generator 38 controls the negative pressure suction cup 43 to achieve the adsorption and fixation of the bottom of the carbonized building block 8. After the negative pressure suction cup 43 adsorbs and fixes the carbonized building block 8, it drives it to move synchronously until the pressure sensor 34 detects the set pressure value. At this time, the carbonized building block 8 is completely and tightly fitted in the building block limiting cavity 32 to complete the positioning.

[0045] Next, the hydraulic cylinder 11 controls the entire assembly processing and transmission mechanism 3 to move the positioned carbonized building block 8 from the positioning station to the engraving station, as shown below. Figure 1 As shown in (A2), the carbonized building block 8, once positioned, is directly below the laser engraver. The laser engraver then performs pattern engraving on the top surface of the carbonized building block 8. During the engraving process, the exhaust fan, U-shaped air pipe, main ventilation pipe 20, branch ventilation pipe 22, hollow collection ring 21, and suction port are used to extract the dust generated during engraving into the processing equipment for purification. After the pattern engraving on the carbonized building block 8 is completed by the laser engraver, the hydraulic cylinder 11 controls the entire combined processing and transmission mechanism 3 to move the engraved carbonized building block 8 from the engraving station to the pattern cleaning station. Figure 1 As shown in (A3), at this time, the arc-shaped chip collection cover 19 is just attached to the outer wall of the hollow sealed cover 5, and the flow port at the bottom of the hollow sealed cover 5 is located in the inner cavity of the arc-shaped chip collection cover 19.

[0046] Subsequently, the rotating component 6 is controlled to rotate 180° by the drive motor 26. The rotating component 6 drives the limiting component 7 and the carbonized building block 8 to rotate 180°. At this time, the carbonized building block 8, which has been carved, enters the inner cavity of the hollow sealed cover 5 with the top opening of the hollow sealed cover 5 blocked by the arc-shaped mounting ring 27. Then, airflow is first delivered into the arc-shaped chip collection cover 19 through the air supply fan, U-shaped air pipe, main ventilation pipe 20 and arc-shaped chip collection cover 19. Since the bottom of the hollow sealed cover 5 is provided with several flow ports, the arc-shaped chip collection cover 19 is filled with airflow. Airflow enters the hollow sealed hood 5 through various vents to clean the grooves and patterns on the surface of the downward-facing carbonized building block 8. After the air supply fan is turned off, the suction fan is restarted. The debris generated by the air supply fan, U-shaped air pipe, main ventilation pipe 20, arc-shaped chip collection hood 19, and vents is extracted from the hollow sealed hood 5 and sent to the processing equipment for purification. This achieves deep cleaning of the carbonized building block 8 after carving, avoiding the need for additional cleaning processes and thus improving the overall carving efficiency of the carbonized building block.

[0047] After cleaning the grooved patterns on the surface of the carbonized building block 8 after carving, the rotating component 6 is rotated 180° in the opposite direction by the drive motor 26. This causes the rotating component 6 to drive the limiting component 7 and the carbonized building block 8 to reset (i.e., the carbonized building block 8 is rearranged to face upwards again). Then, the hydraulic cylinder 11 controls the entire combined processing and transmission mechanism 3 to carry the carbonized building block 8, which has completed multiple processing steps, back to its original position. Figure 1 At the position shown in (A1), after the carbonized building block 8 is released from adsorption and fixation by the negative pressure generator 38 and the negative pressure suction cup 43, the negative pressure positioning component 9 is moved by the electric push rod 25 to complete the reset. During this process, the spherical guide rod 41 slides along the straight groove of the guide channel 29 to the initial position in the inclined groove. At this time, the carbonized building block 8 that has been engraved can be removed and the engraving of the next carbonized building block 8 can be carried out.
