Description

Technical Field

[0002] Currently, the application of composite panels in vehicle transportation and construction is increasing. With the continuous changes in market demand, the application of composite panels is no longer limited to the original assembly methods such as interlocking and gluing, but requires precise cutting, carving, and countersunk hole carving of the panel materials.

[0003] Current engraving machines operate in a single-point mode, with the main engraving steps being feeding, engraving, and unloading. Due to differences in the size of the engraved holes and the specifications of the engraving tools, the machine needs to be stopped to change tools during production, resulting in very low engraving efficiency. Furthermore, the tool changing action can easily lead to tool wear and engraving defects. Each engraving operation also requires position alignment, and manual alignment errors can easily lead to engraving mistakes. In addition, the inspection of the position and size of the engraved holes after engraving relies on manual labor, which can easily cause batch quality losses due to missed inspections.

[0004] Therefore, there is a need to provide a plate engraving device to at least partially solve the above problems. Utility Model Content

[0030] Reference Figures 1 to 5This utility model provides a plate 100 engraving equipment. The plate 100 engraving equipment includes a frame 10, a conveying mechanism 20, a feeding mechanism 30, a plate positioning device 40, an engraving support device 50, an engraving mechanism 60, and a unloading mechanism 70.

[0031] The frame 10, serving as the load-bearing foundation of the entire equipment, is typically constructed from welded or bolted steel sections, providing sufficient rigidity and stability. The conveying mechanism 20 is installed on the upper part of the frame 10, extending from the feed end to the discharge end of the equipment. The loading mechanism 30, located at the feed end of the conveying mechanism 20, is used to transport the sheet metal 100 to be processed onto the conveying mechanism 20. Along the conveying direction of the conveying mechanism 20, a sheet metal positioning device 40 is first installed, positioned upstream of the engraving station. The engraving support device 50 is directly positioned below the engraving station, its top perpendicularly corresponding to the conveying surface of the conveying mechanism 20. The engraving mechanism 60 spans above the conveying mechanism 20 via its own support frame 62, meaning its structure spans both sides of the conveying mechanism 20 and is fixed to the frame 10, allowing the engraving blade 61 to cover the engraving station on the conveying mechanism 20 below. Finally, an unloading mechanism 70 is installed at the end of the conveying mechanism 20 to remove the engraved and inspected sheet metal 100. Optionally, a carving inspection system 90 is installed downstream of the carving station. The carving inspection system 90 is mounted above the conveyor mechanism 20 via a bracket and is used to inspect the passing carved boards 100. This solution constructs a complete automated production line of "feeding-conveying-positioning-carving-inspection-discharging". The frame 10 provides a stable structural foundation. The conveyor mechanism 20 is responsible for the continuous conveying of the boards 100. The loading mechanism 30 achieves automated loading, reducing manual labor. The board positioning device 40 ensures the accurate positioning of the board 100 before carving. The carving support device 50 lifts the board 100 during carving, detaching it from the conveyor mechanism 20 and providing stable support, greatly improving carving accuracy and stability. The carving mechanism 60 is installed across the board, with a reasonable layout that saves space. The optional carving inspection system 90 enables online quality monitoring, promptly detecting defective products. The unloading mechanism 70 completes automated material collection. This layout ultimately achieves continuous and automated production processes, significantly improving production efficiency and product quality.

[0032] The frame 10 includes two sets of reference frames 11 arranged opposite to each other.

[0033] Optionally, the reference frame 11 includes a horizontally extending main body 12 and a vertically extending support portion 13. The main body 12 is an elongated guide and limiting component. The main bodies 12 of the two sets of reference frames 11 are parallel to each other and oppositely arranged on both sides of the width direction DW of the frame 10, together forming the conveying channel of the plate 100. The reference frame 11 is slidably connected to the slide rail 14 via the support portion 13. Specifically, the support portion 13 is provided with a groove, and the support portion 13 is engaged with the slide rail 14 through the groove, allowing the support portion 13 to drive the entire reference frame 11 to move linearly along the slide rail 14 with low friction and high precision. The support portion 13 is also threadedly connected to the lead screw 16 to convert the rotational motion of the lead screw 16 into the linear motion of the reference frame 11.

[0034] Optionally, the reference frame 11 has a plurality of rotatable rolling elements 17 on its inner sidewall facing the plate 100, with a portion of the rolling elements 17 protruding from the surface of the inner sidewall. The rolling elements 17 are preferably balls or rollers, mounted in pre-set slots in the inner sidewall of the reference frame 11 via bearings or pins, with their outer circumferential surfaces protruding from the inner sidewall plane. When the plate 100 contacts the inner side of the reference frame 11 during transport, the rolling elements 17 convert sliding friction into rolling friction. This effectively reduces the frictional resistance between the side of the plate 100 and the reference frame 11, preventing scratches on the surface of the plate 100, while ensuring smooth fine-tuning and centering of the plate 100 in the width direction DW, thus improving positioning accuracy and product yield.

[0035] The frame 10 is equipped with a slide rail 14 and a width adjustment mechanism 15. The slide rail 14 extends along the width direction DW. The slide rail 14 provides a reference and guide for the width adjustment movement. When the width adjustment mechanism 15 is working, it drives the reference frames 11 on both sides to move synchronously towards or away from each other along the slide rail 14 along the width direction DW, thereby changing the distance between the two sets of reference frames 11. Optionally, the width adjustment mechanism 15 includes a width adjustment drive device and a lead screw 16. The width adjustment drive device is a servo motor or a stepper motor, which is firmly fixed to the frame 10 by a motor mounting plate. The lead screw 16 is connected to the output shaft of the width adjustment drive device. The lead screw 16 is threadedly connected to the reference frame 11. When the lead screw 16 is driven to rotate, it can adjust its relative position with the reference frame 11, thereby adjusting the distance between the two sets of reference frames 11. The axis of the lead screw 16 is parallel to the slide rail 14 and extends along the width direction DW of the frame 10.

[0036] The conveying mechanism 20 is mounted between two sets of reference frames 11. The conveying mechanism 20 includes a drive unit 21 and a belt 22. The drive unit 21 is connected to the belt 22 via a chain 23 to drive the belt 22 to rotate. The two ends of the conveying mechanism 20 along its width direction DW are respectively supported or connected to the reference frames 11 on both sides, used to carry and convey the sheet metal 100. As described above, the distance between the two sets of reference frames 11 is adjustable, and since the conveying mechanism 20 is mounted on the reference frames 11, its effective conveying width also changes accordingly. This solution enables rapid and accurate width adaptation, enhances the versatility and production efficiency of the equipment, and reduces equipment investment and changeover time.

[0037] The loading mechanism 30 is located at the feed end of the conveying mechanism 20. The loading mechanism 30 includes a loading and handling device 31. The loading and handling device 31 can be, but is not limited to, a suction cup-type robot, whose base is fixedly mounted on the frame 10 or the ground, located on one side or above the feed end of the conveying mechanism 20. The loading and handling device 31 is capable of transporting and placing the sheet material 100 onto the conveying mechanism 20. The suction cup-type robot is equipped with vacuum suction cups, which use a vacuum generator to generate negative pressure to adsorb the sheet material 100.

[0038] The plate positioning device 40 is typically fixedly mounted on the frame 10 via a bracket, and its installation position is downstream of the engraving station. The plate positioning device 40 includes a liftable positioning baffle 41 and a position sensor 42 for detecting the arrival of the plate 100. The liftable positioning baffle 41 is driven by a cylinder or electric push rod and can move vertically up and down relative to the conveying surface of the conveying mechanism 20. The position sensor 42 can be, but is not limited to, an infrared sensor or a photoelectric sensor, and is installed near or upstream of the engraving station, with its detection beam or detection area pointing towards the conveying channel. When the plate 100 is transported to the engraving station by the conveying mechanism 20, the position sensor 42 is triggered first. The sensor signal causes the control unit to control the positioning baffle 41 to rise, preventing the plate 100 from continuing to move forward and stopping it precisely at the preset engraving station. The positioning baffle 41 ensures that the plate 100 stops accurately at the preset engraving station, guaranteeing the accuracy of subsequent engraving operations.

[0039] A carving support device 50 is vertically and flexibly positioned below the conveyor mechanism 20 at the carving station to lift and support the plate 100 during carving. Specifically, the carving support device 50 is located directly below the carving station. The carving support device 50 is vertically and flexibly connected to the frame 10. Exemplarily, the carving support device 50 includes a support table 51 and a lifting device 52. The support table 51 is a rigid table, and the lifting device 52 can be, but is not limited to, a hydraulic cylinder or a pneumatic cylinder. There can be one or more lifting devices 52. In the non-working state, the top surface of the support table 51 is lower than the bearing surface of the conveyor mechanism 20, ensuring normal conveying of the plate 100. During operation, the lifting device 52 pushes the support table 51 upward, passing through the gaps in the conveyor mechanism 20 (e.g., the gaps between belts 22) or lifting the plate 100, causing it to disengage from the belt 22 and press against the support table 51. When the support table 51 is raised and supports the plate 100, it provides a solid and stable processing platform for the carving mechanism 60, reducing large vibrations during the carving process and improving carving quality.

[0040] The engraving mechanism 60 is positioned above the conveyor mechanism 20. Optionally, the engraving mechanism 60 typically includes a frame 62 spanning the conveyor mechanism 20, an engraving blade 61 mounted on the frame 62, and a drive unit. The drive unit includes an X-axis drive unit 66 for driving the entire engraving blade 61 assembly or the gantry beam to move along the length direction DL (X-axis) of the frame 10, a Y-axis drive unit 66 for driving the engraving blade 61 to move along the width direction DW (Y-axis) of the frame 10, and a Z-axis drive unit 66 for driving the engraving blade 61 to move along the height direction DH (Z-axis) of the frame 10. Optionally, the drive unit can be, but is not limited to, a servo motor or a stepper motor. In this engraving mechanism 60, the engraving blade 61 can reach any point on the plane of the plate 100 for processing. Optionally, a dust cover 63 is provided around the engraving blade 61. The dust cover 63 is a shell surrounding the engraving blade 61 and is connected to the external dust cover 63 via a flexible hose.

[0041] The unloading mechanism 70 is located at the discharge end of the conveying mechanism 20. The unloading mechanism 70 includes an unloading and conveying device 71 for removing the engraved sheet metal 100. Similar to the loading and conveying device 31, the unloading and conveying device 71 has its base fixed near the discharge end. It is used to grab the sheet metal 100 that has completed all processes from the end of the conveying mechanism 20 and transport it to a designated stacking area or the next process equipment. The unloading mechanism 70 automates the end-of-line operation, forming a complete "unmanned" production loop, further reducing labor costs and improving overall line efficiency. Optionally, the unloading and conveying device 71, similar to the loading and conveying device 31, can be, but is not limited to, a suction cup-type robotic arm; details will not be elaborated here.

[0042] Reference Figure 6In some embodiments, the device is equipped with multiple engraving units 110, each of which is a fully functional independent engraving module. Each engraving unit 110 includes an engraving station, an engraving support device 50, and an engraving mechanism 60. Multiple engraving units 110 are arranged sequentially along the conveying direction. That is, on the conveyor line, from the inlet to the outlet, two or more sets of engraving units 110 are arranged sequentially. While one engraving unit 110 is engraving a piece of material 100, a subsequent engraving unit 110 can simultaneously perform the next process on a piece of material 100 that has already completed the previous step, or the system can perform preparatory work such as loading and positioning. In this embodiment, the material 100 to be engraved enters from a single loading mechanism 30 and is placed on the conveying mechanism 20. Subsequently, the material 100 passes sequentially through the first engraving unit 110, the second engraving unit 110, and so on until the last engraving unit 110. After all processes are completed, the material 100 is conveyed to a single unloading mechanism 70.

[0043] Reference Figure 7 and Figure 8 In other embodiments, the device is provided with multiple engraving units 110. These engraving units 110 are arranged side-by-side in the width direction DW, enabling them to process different sheet materials 100 simultaneously. The parallel engraving units 110 can operate independently to process different sheet materials 100 simultaneously. For example, while one sheet material 100 is being engraved in the left unit, another sheet material 100 can be conveyed to the right unit and engraved. This layout fully utilizes the width space of the device, increasing productivity. Sheet materials 100 enter from a single loading mechanism 30. The control unit, according to preset logic, controls the conveying mechanism 20 and the positioning device to alternately or systematically convey the sheet materials 100 to different parallel engraving units 110. The parallel engraving units 110 process different sheet materials 100 simultaneously. After processing, the two sheet materials 100 converge onto the main conveyor line and are sent to a single unloading mechanism 70; or the two sheet materials 100 are each conveyed to a single unloading mechanism 70.

[0044] Reference Figures 6 to 8 Optionally, the above embodiments can be implemented simultaneously, that is, the multiple engraving units 110 set in the equipment adopt a series layout arranged sequentially along the conveying direction and a parallel layout arranged side by side in the width direction DW, together forming a hybrid production line.

[0045] Optionally, the multiple engraving stations include at least two engraving mechanisms 60 configured to perform different engraving programs, wherein at least one engraving station is used for rough engraving and at least another engraving station is used for fine engraving. For example, the engraving mechanism 60 of the first station invokes the rough engraving program, using a larger diameter tool for rapid material removal; the engraving mechanism 60 of the second station invokes the fine engraving program, using a smaller diameter tool for detail finishing and polishing.

[0046] Optionally, the parallel engraving units 110 are configured to perform the same engraving program or different engraving programs. Performing the same engraving program means that the parallel engraving units 110 perform exactly the same engraving operation on the respective processed sheet metal 100, which can be used for mass production of single products. Performing different engraving programs means that the parallel engraving units 110 can simultaneously engrave different patterns, models, or perform different processing, which can be used for multi-variety production.

[0047] The equipment also includes a control unit, which is connected to the conveying mechanism 20, the engraving mechanism 60, and the engraving support device 50. This control unit coordinates the conveying, positioning, and engraving operations of the sheet metal 100 between multiple engraving stations to achieve continuous production. The control unit is the brain of the equipment. It connects to the sensors (such as position sensors 42) and drive devices (such as motors and solenoid valves of hydraulic cylinders) of each mechanism via input / output modules and communication buses. According to a preset logic program, the control unit uniformly commands and coordinates the actions of all mechanisms, resolving the problems of complex and conflicting actions in multi-station equipment, ensuring the efficient, reliable, and orderly automatic operation of the entire production line, and achieving intelligent continuous production.

[0048] Optionally, the engraving equipment for the sheet metal 100 also includes a loading visual recognition device 80. The loading visual recognition device 80 can be, but is not limited to, an industrial camera, typically installed above or to the side of the loading station, with its field of view covering the stacking area of ​​the sheet metal 100 to be loaded. The loading visual recognition device 80 is signal-connected to the loading and handling device 31 to guide the loading and handling device 31 in loading. The signal connection means that the loading visual recognition device 80 is connected to the control unit via a wired or wireless means, and the control unit is then connected to the loading and handling device 31 via a wired or wireless means. The loading visual recognition device 80 captures an image of the sheet metal 100 to be loaded, and through image processing, identifies the outline, size, model, and specific position coordinates of the sheet metal 100 in the stack. This information is transmitted to the control unit via the signal connection, and the control unit then generates control commands to guide the loading and handling device 31 to accurately move to the target position for gripping, and to place the sheet metal 100 onto the conveyor mechanism 20 in the correct posture and position. This solution solves the problems of inaccurate positioning and low efficiency of manual material feeding, realizes intelligent material feeding, improves the accuracy and automation of material feeding, and lays the foundation for subsequent precise positioning and engraving.

[0049] Optionally, the engraving equipment for the sheet metal 100 also includes an engraving inspection system 90, which is located downstream of the engraving station and is used to perform quality inspection on the engraved sheet metal 100. The engraving inspection system 90 can be, but is not limited to, an industrial camera, whose field of view covers the entire width of the conveyor mechanism 20 to ensure comprehensive imaging of the engraved sheet metal 100. The engraving inspection system 90 is signal-connected to the equipment's control unit. Based on the inspection results from the engraving inspection system 90, the control unit can issue control commands to downstream actuators (such as alarms, shutdown devices, sorting devices, etc.).

[0050] The workflow of the engraving inspection system 90 is as follows: When the conveyor mechanism 20 carrying the engraved sheet 100 passes the inspection station, the industrial camera acquires a high-definition image of the sheet 100. The image processing unit preprocesses the acquired image and then compares and analyzes it with pre-stored standard design drawings or qualified sample images to automatically identify whether there are engraving defects, such as missing patterns, out-of-tolerance engraving line dimensions, broken tool marks, surface scratches, and the presence of foreign objects. The inspection result information is transmitted to the control unit in real time via a signal connection. If the inspection result is "qualified," the control unit controls the conveyor mechanism 20 to continue conveying the sheet 100 to the unloading station; if the inspection result is "unqualified," the control unit can immediately trigger an audible and visual alarm to issue a warning, and can selectively control the production line to suspend operation, or control the subsequent sorting mechanism to reject defective products.

The terminology used herein is for descriptive purposes only and is not intended to limit the scope of the invention.
