Description

Technical Field

[0001] The present invention relates to the technical field of door manufacturing, and more particularly to an automated engraving line for door core plates. Background Art

[0002] In the process of door manufacturing, multiple processing steps are usually involved. Different processing steps are located at different workstations. Without the use of mechanical equipment, it is extremely inconvenient to manually transport door panels and door frames between workstations. Therefore, automated processing equipment is usually equipped. In current automated door manufacturing, there is a lack of continuity between different workstation processes. In most processing operations, manual assistance is still required to transfer workpieces between workstations. During flow production, the degree of automation is still relatively low, and the overall processing efficiency still needs to be improved. In some engraving processes for the door surface of door core plates, processes such as loading and unloading the door core plate, transportation, and flipping of the door surface are usually required, which is a cumbersome process. Especially when it comes to large-scale processing, undoubtedly, using a highly automated production line can greatly improve production efficiency and significantly save costs. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an automated engraving line for door core plates.

[0004] The purpose of the present invention is achieved through the following technical solutions:

[0005] An automated engraving line for door core plates, the engraving line includes at least one sub-processing line and at least one flipping mechanism. In the sub-processing line, an inlet conveyor, at least one positioning mechanism, at least one engraving main machine, and an outlet conveyor are arranged in sequence along the processing steps. The flipping mechanism is located between the engraving main machine and the outlet conveyor. The feeding directions of the inlet conveyor and the outlet conveyor are both perpendicular to the feeding directions of other processes in the sub-engraving line.

[0006] In this solution, through the orderly connection of the inlet conveyor, positioning mechanism, engraving main machine, flipping mechanism, and outlet conveyor, the automated engraving line realizes the complete automation of the steps from feeding to processing to discharging of the door core plate engraving process, greatly saving labor costs. At the same time, compared with ordinary flow processing, its processing efficiency is greatly improved. In addition, in the above solution, the automated engraving line includes at least one sub-processing line. Therefore, in actual processing, multiple sub-processing lines can be set according to needs. And since each sub-processing line is relatively independent and will not interfere with the overall system, it is extremely suitable for large-scale engraving processing of door core plates.

[0007] Preferably, a first positioning mechanism, a second positioning mechanism, a first engraving main machine, and a second engraving main machine are provided in the sub-processing line. The first positioning mechanism and the first engraving main machine are respectively arranged between the inlet conveyor line and the flipping mechanism in sequence according to the process; the second positioning mechanism and the second engraving main machine are respectively arranged between the flipping mechanism and the outlet conveyor line in sequence according to the process.

[0008] In this solution, by increasing the number of positioning mechanisms and engraving main machines in the sub-processing line, it adapts to the "preliminary positioning - engraving - flipping - preliminary positioning - engraving" required for the engraving processing of the door core board, increases the processing stations, so as to shorten the residence time of the door core board outside the processing stations, which helps to improve the processing efficiency. Compared with the situation where there is only a single positioning mechanism and engraving main machine in the sub-processing line, after one side of the door core board is engraved, it is flipped by the flipping mechanism, and then it still needs to bypass the engraving main machine to return the door core board to the positioning mechanism to complete the preliminary positioning work, and then pass through the engraving main machine to complete the engraving of the other side of the door core board. Obviously, its efficiency is lower than the above solution.

[0009] Preferably, a door panel conveying device is provided between the second engraving main machine and the outlet conveyor line. This device plays a buffering role. Since the discharging direction of the door core board on the engraving main machine is perpendicular to the direction of the outlet conveyor line, when the door core board is output from the engraving main machine, due to the transmission power of the outlet conveyor line, one end of the door panel will be driven, while the other end of the door panel will bump into the engraving main machine, and the door panel conveying device can assist in conveying the door core board to the outlet conveyor line. Specifically, after the door core board completely leaves the engraving main machine, the door panel conveying device will convey the door core board to the outlet conveyor line, avoiding the above defects.

[0010] Furthermore, a first pushing component for pushing the door core board towards the outlet conveyor line is provided on the door panel conveying device. The first pushing component includes a first air cylinder and a first pushing plate. The first air cylinder, the cylinder body of the first air cylinder is fixedly connected to both sides of the frame of the device. The first pushing plate is arranged perpendicular to the direction of material transportation. At both ends of the first pushing device, a first lifting component is connected, and the first lifting component is fixedly connected to the piston rod end of the first air cylinder.

[0011] Preferably, a door panel transfer device is erected on the inlet conveyor line perpendicular to the direction of material transportation. Since the direction of the inlet conveyor line is perpendicular to the feeding direction of the door core board in the sub-processing line, it is necessary to complete the vertical transfer of the door panel on the inlet conveyor line to transport the door core board to the sub-processing line.

[0012] Further, the door panel transfer device includes a connecting frame, which is fixedly connected to the frame of the entrance conveyor line. A door panel interception component and a second pushing component are provided on the connecting frame. The door panel interception component includes a second cylinder and an interception plate. The cylinder body of the second cylinder is fixed on the connecting frame, and the interception plate is fixedly connected to the piston rod of the second cylinder. The second pushing component includes a second pushing plate and a transmission component connected to the second pushing plate. The transmission component is fixed on the connecting frame, and the second pushing plate is slidably connected to the connecting frame. When the door core plate on the entrance conveyor line is transported to the corresponding position, the interception plate blocks the door panel through the second cylinder to prevent it from continuing to be transported forward along the conveyor line. At the same time, the pushing plate in the second pushing component vertically pushes the door core plate from the entrance conveyor line into the sub-processing line under the action of the transmission device. After the door core plate completely leaves the entrance conveyor line, the door panel interception component and the second pushing component reset and wait for the next action.

[0013] Preferably, the flipping mechanism includes a base and two groups of parallel flipping wheels. The flipping wheels are rotatably matched with the base. A first roller group and a second roller group are fixedly connected to the flipping wheels. Both the first roller group and the second roller group include roller frames and belt transmission devices connected to the roller frames. A second lifting component for controlling the lifting and moving of the belt transmission device is provided on the first roller group or the second roller group. In the flipping wheel mechanism, the door core plate is clamped and flipped through the first roller group, the second roller group and the second lifting component in the flipping wheels. During this process, the belt transmission devices on the first roller group and the second roller group can realize the automatic feeding and feeding of the door core plate. Specifically, first, the door core plate is transported to the center of the first roller group and the second roller group through its belt transmission device, and then the second lifting component is controlled to make the first roller group and the second roller group press the door core plate. Then, the flipping wheels rotate 180°, completing the flipping of the door core plate. After that, the second lifting component controls to loosen the door core plate, and the belt transmission device outputs the door core plate to the next processing procedure.

[0014] Preferably, a sliding component is provided at the bottom of the flipping mechanism. The sliding component includes a guide rail and rollers adapted to the guide rail. The guide rail is fixed on the ground of the site. The flipping mechanism is slidably matched with the guide rail through the rollers, and the arrangement direction of the guide rail is parallel to the directions of the entrance conveyor line and the exit conveyor line. The flipping mechanism can move between multiple sub-processing lines through the guide rail, enabling a single flipping mechanism to flip and process the door core plates in multiple sub-processing lines. On the one hand, it can improve the utilization rate of the flipping mechanism, and on the other hand, it can reduce the setting of the flipping mechanism, further reducing the production line cost.

[0015] Further, the positioning mechanism includes a third pushing component, a reference plate, and a feeding stop component. The third pushing component and the reference plate are arranged in parallel on both sides of the machine frame along the feeding direction. The feeding stop component is installed at one end of the machine frame perpendicular to the feeding direction. The third pushing component includes a third air cylinder and a third pushing plate. The cylinder body of the third air cylinder is fixed to the machine frame, and the third pushing plate is fixedly connected to the end of the piston rod of the third air cylinder, and the third pushing plate is parallel to the reference plate. The feeding stop component includes a feeding stop plate and a third lifting component connected to the feeding stop plate. Specifically, when the door core plate reaches the corresponding position, the feeding stop component controls the door core plate to stop moving. Subsequently, the third pushing component pushes the door panel along the edge of the door core plate towards the reference plate. Taking the reference plate as the scale reference, the door core plate is initially positioned in a certain direction to complete the positioning work. Finally, the third pushing component and the feeding stop component reset, and the door core plate is conveyed to the next processing station.

[0016] Further, position detection sensors for detecting the position of the door panel are provided in each process on the engraving line. By monitoring the real-time position of the door core plate in each process through the position detection sensors, the corresponding control center controls the start and stop of the mechanisms and components involved in the process to make them coordinate with each other, increasing the convenience and efficiency of the production line.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The automatic engraving line for door core plates provided by the present invention includes a door core plate positioning mechanism, a flipping mechanism, an engraving mechanism, and an automatic feeding and conveying line, which can realize the automatic engraving of door core plates and other auxiliary processes, with a high degree of automation. At the same time, it has multiple sub-processing lines, can meet the needs of batch processing, has high processing efficiency and low labor cost. Brief Description of the Drawings

Specific embodiments

[0027] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0028] Please refer to Figure 1 and Figure 2 , the present invention provides an automatic engraving line for door core boards. This automatic engraving line includes at least one sub - processing line and at least one flipping mechanism 4. In the sub - processing line, an entrance conveyor line 1, at least one positioning mechanism, at least one engraving main machine, and an exit conveyor line 8 are arranged in sequence along the processing procedures. And the flipping mechanism 4 is located between the engraving main machine and the exit conveyor line 8. The feeding directions of the entrance conveyor line 1 and the exit conveyor line 8 are both perpendicular to the feeding directions of other procedures in the sub - engraving line.

[0029] The mechanisms and technologies involved in the engraving main machine in this embodiment are existing, so they will not be elaborated here.

[0030] In this embodiment, through the orderly connection of the entrance conveyor line 1, the positioning mechanism, the engraving main machine, the flipping mechanism 4, and the exit conveyor line 8, this automatic engraving line realizes the complete automation of the steps from feeding to processing to discharging of the door core board engraving process, greatly saving labor costs. At the same time, compared with ordinary flow processing, its processing efficiency is greatly improved. In addition, in the above - mentioned solution, the automatic engraving line includes at least one sub - processing line. Therefore, in actual processing, multiple sub - processing lines can be set according to needs. And because each sub - processing line is relatively independent and will not interfere with the overall system, it is extremely suitable for large - batch engraving processing of door core boards.

[0031] In the sub - processing line, there are a first positioning mechanism 2, a second positioning mechanism 5, a first engraving main machine 3 and a second engraving main machine 6. The first positioning mechanism 2 and the first engraving main machine 3 are respectively arranged between the inlet conveyor line 1 and the flipping mechanism 4 in sequence according to the process; the second positioning mechanism 5 and the second engraving main machine 6 are respectively arranged between the flipping mechanism 4 and the outlet conveyor line 8 in sequence according to the process.

[0032] Compared with some embodiments in which there is only a single positioning mechanism and engraving main machine in the sub - processing line, after one side of the door core board is engraved, it is flipped by the flipping mechanism 4, and then it still needs to bypass the engraving main machine to return the door core board to the positioning mechanism to complete the initial positioning work, and then pass through the engraving main machine to complete the engraving of the other side of the door core board. Obviously, its efficiency is relatively low. In this embodiment, by increasing the number of positioning mechanisms and engraving main machines in the sub - processing line, it adapts to the steps of "initial positioning - engraving - flipping - initial positioning - engraving" required for the engraving processing of the door core board, increases the processing stations, so as to shorten the residence time of the door core board outside the processing stations, which helps to improve the processing efficiency.

[0033] At the same time, please refer to Figure 2 and Figure 7 , since the discharging direction of the door core board on the engraving main machine is perpendicular to the direction of the outlet conveyor line 8, when the door core board is output from the engraving main machine, because the outlet conveyor line 8 has transmission power, one end of the door panel will be driven, while the other end of the door panel will bump into the engraving main machine.

[0034] For this reason, please refer to Figure 2 and Figure 3 , in this embodiment, a door panel conveying device 7 is arranged between the second engraving main machine 6 and the outlet conveyor line 8. This device can play a buffering role. Specifically, after the door core board completely leaves the engraving main machine, the door panel conveying device 7 will convey the door core board onto the outlet conveyor line 8, which can avoid the above - mentioned problems. The door panel conveying device 7 is provided with a first pushing assembly for pushing the door core board towards the outlet conveyor line 8. The first pushing assembly includes a first air cylinder 9 and a first pushing plate 10. The first air cylinder 9, the cylinder body of the first air cylinder 9 is fixedly connected to both sides of the frame of the device. The first pushing plate 10 is arranged along the direction perpendicular to the material conveying. At both ends of the first pushing device 10, there are first lifting assemblies connected, and the first lifting assemblies are fixedly connected to the piston rod end of the first air cylinder. In the initial state, the first pushing plate 10 is located at one end of the frame of the door panel conveying device 7 close to the second engraving main machine 6.

[0035] After the door core board is engraved by the second engraving main machine 6, the door core board is output to the door panel conveying device 7. During this process, the discharging direction of the engraving main machine is the same as the feeding direction of the door panel conveying device 7. Therefore, there will be no situation where the door panel bumps into the engraving main machine. After the center of gravity of the door core board moves onto the door panel conveying device 7, the first air cylinder 9 located on the frame of the device controls the first lifting assembly and the first pushing plate 10 to move towards the second engraving main machine 6. After reaching the corresponding position (when the first pushing plate 10 is between the end of the door core board and the second engraving main machine 6), the first lifting assembly controls the first pushing plate 10 to move vertically downward to the end of the door core board. Subsequently, the first air cylinder 9 returns, and its piston rod controls the first pushing plate 10 to "pull" the door core board towards the outlet conveying line 8. When the first air cylinder 9 completes its return movement, one end of the door core board has reached the outlet conveying line 8, and the center of gravity of the door core board has also shifted to the outlet conveying line 8. After the door core board detaches from the first pushing plate 10, the first lifting assembly controls the first pushing plate 10 to lift, waiting for the next door core board to be pushed. Under the transportation of the outlet conveying line 8, the door core board finally completely detaches from the door panel conveying device 7 to achieve discharging and offline. During this process, due to the non-parallel transportation directions of the door panel conveying device 7 and the outlet conveying line 8, the door core board tilts and rotates. However, at this time, the door core board has moved away from the second engraving main machine 6, so it will not cause bump damage to the second engraving main machine 6. At the same time, since the feeding speeds of the door panel conveying device 7 and the outlet conveying line 8 are relatively slow and stable, the door core board will not be damaged by bumping due to tilting and rotating.

[0036] In this embodiment, the first lifting assembly can be selected as an air cylinder with characteristics such as stable stroke and precise action.

[0037] In addition, please refer to Figure 2 and Figure 4 , in this embodiment, a door panel transfer device is installed on the entrance conveying line 1 along the direction perpendicular to the material conveying. Since the direction of the entrance conveying line 1 is perpendicular to the feeding direction of the door core board in the sub-processing line, the vertical transfer of the door panel needs to be completed on the entrance conveying line 1 to transport the door core board to the sub-processing line.

[0038] The door panel transfer device includes a connecting frame 11 fixedly connected to the entrance conveyor line 1. The connecting frame 11 is erected on both sides of the frame of the entrance conveyor line 1 and is parallel to the feeding direction of the entrance conveyor line 1. A door panel interception assembly for intercepting the door core panel on the entrance conveyor line and a second pushing assembly for pushing the door core panel in the vertical direction are provided on the connecting frame 11. Specifically, the door panel interception assembly includes an interception plate 13 and second cylinders 12 connected to both ends of the interception plate 13. The interception plate 13 is fixedly connected to the piston rod of the second cylinder 12, and the cylinder body of the second cylinder 12 is fixed to the connecting frame 11, so that the interception plate 13 can move up and down in the vertical direction under the control of the second cylinder 12, thereby realizing the interception of the door core panel.

[0039] The second pushing assembly includes a second pushing plate 14 and a transmission component 15 connected to the second pushing plate 14 and providing driving force. The transmission component 15 is fixed to the connecting frame 11, and the second pushing plate 14 is slidably connected to the connecting frame 11. Correspondingly, a slide rail adapted to the second pushing plate 14 is provided on the connecting frame 11. The slide rail is parallel to the horizontal plane, and the second pushing plate 14 is slidably connected to the slide rail through some connecting pieces. In this embodiment, the transmission component 15 includes a motor and an actuator for power transmission. The actuator adopts a chain drive form of power transmission, which specifically includes a driving sprocket, a driven sprocket and a chain. The driving sprocket and the driven sprocket are fixed relative to the connecting frame 11 and are located at both ends of the connecting frame 11. The chain is fixedly connected to the second pushing plate 14. Thus, through the chain, the power of the motor is transmitted to the second pushing plate 14 and the torque is converted into horizontal movement on the slide rail. Therefore, by controlling the forward and reverse rotation of the motor in the door panel transfer device, the second pushing plate 14 is controlled to reciprocate horizontally.

[0040] Thus, when the door core panel on the entrance conveyor line 1 is transported to the corresponding position along its feeding direction, the second cylinder 12 on the connecting frame 11 controls the interception plate 13 to descend vertically, intercepting the door core panel and blocking its continued forward transmission. The door core panel slides relative to the entrance conveyor line 1. At the same time, under the action of the transmission component 15, the second pushing plate 14 in the second pushing assembly pushes the door core panel from the side of the entrance conveyor line 1 along the direction perpendicular to the feeding direction of the entrance conveyor line 1 into the sub-processing line. After the door core panel completely leaves the entrance conveyor line 1, the transmission component 15 controls the second pushing plate 14 to reset, and at the same time, the second cylinder 12 controls the interception plate 13 to lift and return to its original position. Wait for the next transfer of the door core panel.

[0041] Please refer to Figure 5, in this embodiment, the flipping mechanism 4 includes a base and two sets of parallel flipping wheels 16. Moreover, the two sets of flipping wheels 16 are both perpendicular to the horizontal plane, and the flipping wheels 16 are rotatably engaged with the base. Correspondingly, components adapted for the rotational connection of the flipping wheels 16 are provided on the base. Specifically, these components include supports and pulleys symmetrically arranged on both sides of the flipping wheels 16. The supports are fixedly connected to the base, and the pulleys are rotatably connected to the supports. The flipping wheels 16 are connected to the base through the pulleys. A chute adapted for the pulleys is provided on the outer circumference of the flipping wheels 16, and through this chute, the flipping wheels 16 achieve rotation relative to the base.

[0042] Of course, an actuator for driving the rotation of the two sets of flipping wheels 16 is provided on the base, and the actuator provides driving force for the rotation of the flipping wheels 16. In this embodiment, the actuator can select the transmission form of chain drive, and the flipping wheels 16 are connected to the motor in the actuator through a transmission chain. In some other embodiments, the actuator can also adopt the form of gear drive. Specifically, the above-mentioned pulleys should be replaced with gears accordingly, and teeth adapted for the gears also need to be machined in the chute on the outer circumference of the flipping wheels 16. In this way, the flipping wheels 16 are rotationally connected to the base in the form of gear meshing. Its advantage is that, compared with the above-mentioned chain drive form, the control of the rotation angle is more precise. However, its disadvantages are also obvious. The processing cost of the gears and teeth is relatively higher, and at the same time, since the size difference between the used gears and the flipping wheels is large, the transmission ratio is very small, so the rotation speed of the flipping wheels 16 will be relatively slow.

[0043] A first roller group 17 and a second roller group 18 are fixedly connected to the flipping wheels 16. Moreover, both the first roller group 17 and the second roller group 18 include roller frames and belt drive devices connected to the roller frames. A second lifting component for controlling the lifting and moving of the belt drive devices in the first roller group 17 or the second roller group 18 is provided on the first roller group 17 or the second roller group 18. Specifically, in this embodiment, the second lifting component can be provided on the roller frame of the first roller group 17 to control the lifting and moving of the belt drive device located on the first roller group 17, or can be provided on the roller frame of the second roller group 18 to control the lifting and moving of the belt drive device located on the second roller group 18, so as to realize the cooperation of the first roller group 17 and the second roller group 18 to clamp the door frame or the door panel. In the flipping wheel 16 mechanism, through the first roller group 17 and the second roller group 18 and the second lifting component in the flipping wheels 16, the door core board is clamped and flipped. During this process, the belt drive devices located on the first roller group 17 and the second roller group 18 can realize the automatic feeding and feeding of the door core board.

[0044] Specifically, on the production line, when it comes to the process of flipping the door core board, the door core board is transported from the first engraving main machine 3 to the flipping mechanism 4. During this process, the belt drive device in the second roller group 18 in the flipping mechanism 4 is started. Under the action of the conveyor belt of the door core board's own weight, the door core board gradually moves to the exact center of the second roller group 17 in the flipping mechanism 4. Subsequently, this belt drive device stops working. And the second lifting assembly located on the roller racks of the first roller group 17 or the second roller group 18 controls the first roller group 17 and the second roller group 18 to complete the fitting and clamping of the door core board. Then, the actuator for driving the flipping wheel 16 to rotate located on the base is started. The flipping wheel 16 rotates 180° clockwise or counterclockwise driven by the transmission chain and then stops and locks. At this time, the first roller group 17 and the second roller group 18 complete the position exchange, that is, the second roller group 18 is above the first roller group 17. After that, the second lifting assembly controls the first roller group 17 or the second roller group 18 to lift and lower to release the clamping of the door core board. At this time, the weight of the door core board is borne by the first roller group 17. The belt drive device in the first roller group 17 is started, and the door core board that has completed the flipping leaves the flipping mechanism 4 under the action of the conveyor belt and enters the second positioning mechanism 5 to complete the subsequent processing procedures. After the door core board completely leaves the flipping mechanism 4, the belt drive device on the first roller group 17 stops working, and then the entire flipping mechanism 4 can maintain this state to wait for the next flipping work of the door core board. Correspondingly, when starting the second flipping of the door core board, the flipping action is opposite to the action sequence of the above process. Specifically, the belt drive device in the first roller group 17 transports the door core board onto the flipping mechanism 4. Subsequently, the motor in the actuator rotates in the reverse direction, and then the flipping wheel 16 rotates 180° in the reverse direction to achieve the flipping of the door core board. Finally, the belt drive device in the second roller group 18 sends out the door core board that has been turned over.

[0045] A sliding assembly is provided at the bottom of the flipping mechanism 4. The sliding assembly includes a guide rail 20 and rollers 19 adapted to the guide rail 20. The guide rail 20 is fixed to the ground of the site. The flipping mechanism 4 is slidably engaged with the guide rail 20 through the rollers 19, and the arrangement direction of the guide rail 20 is parallel to the directions of the inlet conveyor line 1 and the outlet conveyor line 8. The flipping mechanism 4 can move between multiple sub-processing lines through the guide rail 20, enabling one flipping mechanism 4 to participate in the flipping processing of the door core board in multiple sub-processing lines. On the one hand, it can improve the utilization rate of the flipping mechanism 4, and on the other hand, it can reduce the setting of the flipping mechanism 4, which can further reduce the production line cost.

[0046] The second lifting assembly in this embodiment can adopt a cylinder with stable stroke and precise action.

[0047] Please refer to Figure 6, the positioning mechanism includes a third pushing component, a reference plate 21 and a feeding stop component. The third pushing component and the reference plate 21 are arranged in parallel on both sides of the frame along the feeding direction. The feeding stop component is installed at one end of the frame perpendicular to the feeding direction. The third pushing component includes a third cylinder 22 and a third pushing plate 23. The cylinder body of the third cylinder 22 is fixed on the frame. The third pushing plate 23 is fixedly connected to the end of the piston rod of the third cylinder 22, and the third pushing plate 23 is parallel to the reference plate 21. The feeding stop component includes a feeding stop plate 24 and a third lifting component 25 connected to the feeding stop plate 24. The third lifting component 25 in this embodiment can also be a cylinder or a hydraulic cylinder.

[0048] Specifically, when the door core board reaches the corresponding position, the feeding stop plate 24 moves downward under the control of the third lifting component 25 to intercept the door core board and prevent it from continuing to move. Subsequently, the third pushing component pushes the door core board along the edge of the door core board towards the direction of the reference plate 21 and docks it along the reference plate 21. Taking the reference plate 21 parallel to the feeding direction as the positioning reference, the door core board completes the initial positioning work in this direction. Then, the third pushing plate 23 returns to the initial position, and the third lifting component controls the feeding stop plate 24 to lift and reset, "releasing" the door core board, and the door core board then continues to move along the feeding direction and is transported to the next processing station.

[0049] In this embodiment, corresponding point detection sensors for detecting the position of the door core board are provided in each process on the engraving line. The real-time position of the door core board in each process is monitored by the point detection sensors, and the corresponding control center controls the start and stop of the mechanisms and components involved in the process to make them coordinate with each other, increasing the convenience and efficiency of the production line.

[0050] The automatic engraving line for door core boards provided by the present invention includes a door core board positioning mechanism, a flipping mechanism, an engraving mechanism, and an automatic feeding and feeding line, which can realize the automatic engraving of door core boards and other auxiliary processes, with a high degree of automation. At the same time, it has multiple sub-processing lines and can meet the needs of batch processing, with high processing efficiency and low labor cost.

[0051] The above is only the preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications, and environments, and can be changed within the scope of the concept described herein through the above teachings or the technology or knowledge in related fields.
