Description

Technical Field

[0001] This invention belongs to the technical field of engraving and milling equipment, and relates to an engraving and milling machine. Background Technology

[0002] A CNC engraving and milling machine is a device that uses numerical control to engrave and process workpieces such as wood and stone. Compared with manual engraving, it has higher processing efficiency and precision, and therefore has been widely used, even replacing manual engraving technology. The emergence of CNC engraving and milling machines has laid the foundation for the mass production of products.

[0003] For example, a four-process wood carving machine disclosed in Chinese patent literature (application number CN201820600481.3; publication number CN208682483U) includes a support base, conveyor belt, processing table, first clamping plate, second clamping plate, carving knife, first electric push rod, and support plate. Symmetrical baffles are arranged on both sides of the processing table. During processing, the distance between the two baffles is adjusted to match the length of the wood. After adjustment, the baffles are locked using limit knobs. The wood is then placed on the conveyor belt and transported to below the carving knife. The electric push rod then lifts the support plate, which holds the wood in place. The carving knife then carves the wood. The two baffles in this machine allow the distance between them to be adjusted according to the length of the wood, ensuring the wood remains level and does not tilt forward or backward or vertically.

[0004] This engraving machine has several shortcomings during the engraving process: First, it uses a horizontal placement method for transporting wood. When the wood reaches the bottom of the processing platform, the conveyor belt stops, allowing the pallet to move upwards and lift the wood through the grooves on the pallet. However, at the instant the conveyor belt stops, the wood, due to its initial velocity, is difficult to stop immediately. Since workpieces of different materials or sizes have varying masses and inertia, they tend to continue moving forward unpredictably after the conveyor belt stops. This often results in the workpiece not aligning properly with the grooves on the pallet after the conveyor belt stops, and the workpiece may even tilt, causing the pallet to fail to lift the workpiece stably or at all, leading to automatic feeding failure. Secondly, while each pallet has two grooves, allowing for the simultaneous lifting and processing of two pieces of wood, improving efficiency, the distance between the two grooves on the pallet is constant. Therefore, when the pallet lifts two pieces of wood simultaneously, the distance between the two pieces on the conveyor belt must equal the distance between the two grooves. However, when wood is placed manually onto the conveyor belt by workers, it's difficult to ensure that every adjacent piece of wood on the conveyor belt is evenly spaced and equal to the distance between the two trays. This often leads to trays failing to lift the wood. Consequently, the structure of this engraving machine results in low stability and reliability of the automatic feeding process, making it practically impossible to meet the requirements for automatic workpiece feeding.

[0005] Currently, those skilled in the art mainly use the following technical means to solve the above problems:

[0006] 1. Install a carrier for positioning timber on the conveyor belt. In automated production equipment, using carriers on the conveyor belt to position workpieces is a very common technique. After installing a carrier on the conveyor belt, the carrier fixes the position of the workpiece relative to the conveyor belt. This ensures the positional accuracy of the workpiece after the conveyor belt stops, thus ensuring that the workpiece is aligned with the tray's groove and that the tray stably lifts the workpiece each time.

[0007] 2. Use a pallet with an adjustable lifting position. When there is a deviation between the stopping position of the wood and the lifting position of the pallet, adjust the lifting position of the pallet to ensure that the pallet can stably lift the wood each time.

[0008] 3. The conveyor system uses a side-by-side, close-to-each-other-woods-carrying method. The wood pieces are arranged side-by-side and close to each other on the conveyor belt, which solves the problem of tilting during wood transport. Summary of the Invention

[0009] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a milling and engraving machine that solves the problem of difficulty in achieving automatic material feeding in existing milling and engraving machines.

[0010] The objective of this invention can be achieved through the following technical solution: a milling machine, comprising a frame and a workpiece clamping mechanism disposed on the frame, wherein the frame is further provided with a conveying assembly capable of supporting horizontal conveying of workpieces and a transfer component capable of transferring workpieces from the conveying assembly to the workpiece clamping mechanism, characterized in that the frame is provided with a first guide component and a second guide component, wherein a narrow guide channel is formed between the first guide component and the second guide component and the guide channel extends along the conveying direction of the conveying assembly, and the frame is further provided with a drive structure capable of driving the first guide component and / or the second guide component to perform horizontal reciprocating translation along the conveying direction perpendicular to the conveying assembly.

[0011] This engraving and milling machine is mainly used for processing strip-shaped workpieces. During processing, the workpiece is first placed in the guide channel, so that the length direction of the workpiece is consistent with the length direction of the guide channel. The workpiece is conveyed forward under the action of the conveying component. When the workpiece is conveyed to the picking position of the transfer component, the transfer component extends into the guide channel to move the workpiece to the workpiece clamping mechanism for positioning. Finally, the engraving component on the engraving and milling machine processes the workpiece.

[0012] Because a narrow guide channel is formed between the first and second guide members, and this channel extends along the conveying direction of the conveying assembly, the width of the elongated workpiece is limited as it moves within the guide channel. Simultaneously, the drive structure enables the first and / or second guide members to reciprocate horizontally along a direction perpendicular to the conveying assembly, allowing the width of the guide channel to be adjusted to be slightly larger than the workpiece's width. This reduces the frictional resistance between the first and second guide members and the workpiece, ensuring smooth forward transport. Furthermore, it effectively limits the workpiece's width-direction offset, providing better guidance for its movement. This ensures the workpiece moves along a preset trajectory, guaranteeing that each time the transfer member inserts between the first and second guide members, it accurately acts on the workpiece for transfer. Furthermore, when the workpiece reaches the pick-up position of the transfer component, it may come into contact with the first or second guide component. At this point, the drive structure can move the first and / or second guide components away from the workpiece to avoid the transfer component, allowing it to extend into the guide channel and transfer the workpiece. After the transfer component completes one transfer cycle and retracts, the first and / or second guide components are translated and reset under the action of the drive structure. This ensures that the first and / or second guide components return to their initial guiding state, guaranteeing that the next workpiece in the guide channel is well guided for stable transfer by the transfer component. Clearly, through the above structural design improvements, this engraving and milling machine significantly improves the stability and reliability of the automatic feeding process, thus meeting the automatic feeding requirements of automated production processes.

[0013] In the aforementioned engraving and milling machine, the material transfer component is a robotic arm, which can move up and down and is positioned below the guide channel. The material transfer component is located below the guide channel, while the workpiece is confined within the guide channel. This ensures that the material transfer component can effectively grip the workpiece after each ascent, guaranteeing the stability and reliability of the automatic feeding process of the engraving and milling machine. The robotic arm, when closed, can stably grip the workpiece, preventing it from shaking during transport and ensuring that the workpiece is positioned precisely after each ascent. This, in turn, guarantees the positioning accuracy of the workpiece on the workpiece clamping mechanism, resulting in high engraving precision for the engraving and milling machine.

[0014] In the aforementioned engraving and milling machine, the frame has a working platform, and the conveying assembly supports the horizontal conveying of workpieces along the longitudinal direction of the working platform. At least two sets of first and second guide components are arranged sequentially along the transverse direction of the working platform. A guide channel is formed between the first and second guide components in each set. Below each guide channel are at least two transfer components arranged at intervals along the longitudinal direction of the working platform. Preferably, two transfer components are respectively arranged below each guide channel, and these two transfer components can act on the two ends of the strip-shaped workpiece, making the workpiece conveying process more stable. By setting multiple sets of first and second guide components, the engraving and milling machine can process multiple workpieces each time, improving processing efficiency.

[0015] In the aforementioned engraving and milling machine, both the first and second guide components are straight strips and are positioned on the upper part of the conveying assembly. The length of both the first and second guide components extends along the conveying direction of the conveying assembly. The straight shape of both the first and second guide components minimizes frictional resistance between the workpiece and the first and second guide components as the workpiece is conveyed within the guide channel, allowing for smooth forward transport. Furthermore, the relatively small width of these first and second guide components reduces the required width of the work platform when multiple sets are installed, thus decreasing the overall size of the engraving and milling machine. The placement of the first and second guide components on the upper part of the conveying assembly prevents interference with the conveying assembly during movement, facilitating the movement of the first and / or second guide components on the work platform.

[0016] In the aforementioned engraving and milling machine, a front mounting beam is provided at the upper part of the front end of the working platform, and a rear mounting beam is provided at the upper part of the rear end of the working platform. The front ends of each first guide component and each second guide component are slidably connected to the front mounting beam, and the rear ends of each first guide component and each second guide component are slidably connected to the rear mounting beam. Because the working platform of the engraving and milling machine has a large longitudinal distance, the first and second guide components also require a relatively long length. Through the above design, both ends of each first and second guide component are supported, ensuring the levelness and stability of the first and second guide components, thereby better guiding the workpiece and improving the reliability and operational stability of the engraving and milling machine.

[0017] In the aforementioned engraving and milling machine, the conveying assembly includes several feeding rollers arranged longitudinally and at intervals along the working platform. The length direction of each feeding roller is transversely arranged along the working platform. Below each guide channel, a movable front support is provided. The front support is located in front of the foremost transfer component within the corresponding guide channel. All feeding rollers are set at the same height, and after the transfer component and the front support move downwards, their top surfaces are lower than or flush with the upper edge of the feeding rollers. By setting the front support, the forward conveying stroke of the workpiece can be limited, and each time the workpiece is conveyed above the transfer component, it can be precisely positioned at a preset clamping position, ensuring that the transfer component acts on the workpiece at the same position each time and achieves stable workpiece clamping. After processing, the transfer component places the finished workpiece onto the conveying assembly. At this point, the transfer component and the front support move downwards, ensuring that their top surfaces are below or flush with the upper edge of the feeding rollers. This guarantees that the finished workpiece can continue to be conveyed forward to the unloading station or the next processing station. Preferably, the work platform is equipped with a drive mechanism that can drive each feeding roller to rotate synchronously. Alternatively, some feeding rollers can rotate actively, while the remaining rollers rotate passively without the power to do so.

[0018] In the aforementioned engraving and milling machine, the conveying assembly includes at least three conveyor belts arranged longitudinally along the working platform. The two sides of each conveyor belt are located at the two sides of the working platform, and the material transfer components are positioned within the intervals between adjacent conveyor belts. Preferably, there are three conveyor belts, with two material transfer components positioned below each guide channel. One material transfer component is located within the interval between the front conveyor belt and the middle conveyor belt, and the other material transfer component is located within the interval between the rear conveyor belt and the middle conveyor belt.

[0019] In the aforementioned engraving and milling machine, the drive structure includes a first linkage bar connected to each first guide member and a second linkage bar connected to each second guide member. The frame is also equipped with a drive source one capable of driving the first linkage bar to move horizontally laterally and a drive source two capable of driving the second linkage bar to move horizontally laterally. This design allows for adjustment of the positions of both the first and second guide members. After adjustment, a gap is maintained between both the first and second guide members and the workpiece, facilitating the robotic arm to grip the workpiece from the bottom and improving the stability of workpiece transfer.

[0020] In the aforementioned engraving and milling machine, a first linkage bar and a second linkage bar are slidably mounted on both the front and rear mounting beams. Each first linkage bar is connected to the aforementioned drive source one, and each second linkage bar is connected to the aforementioned drive source two. The front end of each first guide component is connected to the first linkage bar on the front mounting beam, and the front end of each second guide component is connected to the second linkage bar on the front mounting beam. The rear end of each first guide component is connected to the first linkage bar on the rear mounting beam, and the rear end of each second guide component is connected to the second linkage bar on the rear mounting beam. Because the first and second guide components are relatively long, this design allows both ends of the first and second guide components to move under the action of either drive source one or drive source two. This results in smoother movement of the first and second guide components, reducing the likelihood of tilting or bending, and thus providing better guidance for the workpiece.

[0021] In the aforementioned engraving and milling machine, a front mounting beam is provided at the upper part of the front end of the working platform, and a rear mounting beam is provided at the upper part of the rear end of the working platform. The drive structure includes four racks, which are slidably arranged in pairs on the front and rear mounting beams. The front end of the first guide component is connected to one of the racks on the front mounting beam, the front end of the second guide component is connected to the other rack on the front mounting beam, the rear end of the first guide component is connected to one of the racks on the rear mounting beam, and the rear end of the second guide component is connected to the other rack on the rear mounting beam. Each rack is connected to a motor gear mechanism that can drive the rack to move horizontally along the working platform.

[0022] In the aforementioned engraving and milling machine, each guide channel is equipped with a guide rail extending longitudinally along the work platform. Each material transfer component below each guide channel is slidably connected to the guide rail via a sliding seat. Each pair of adjacent feeding rollers on the upper part of the guide rail has a gap sufficient for the material transfer component to pass through. Preferably, each guide rail has two material transfer components. By setting the guide rails, the distance between the two material transfer components can be adjusted according to workpieces of different lengths, allowing the two components to act on the workpiece at an optimal position, improving the stability of the workpiece transfer process, and thus making the automatic feeding process of the engraving and milling machine stable and reliable.

[0023] In the above-mentioned engraving and milling machine, a guide rail extending longitudinally along the working platform is provided below the conveying component. Two support beams are slidably connected on the guide rail. The two support beams are spaced apart longitudinally along the working platform. A linkage plate is slidably provided on each support beam. A screw guide rail structure that can drive the linkage plate to slide horizontally back and forth along the working platform is provided between the linkage plate and the corresponding support beam. Each linkage plate is provided with the above-mentioned material transfer components that are equal in number and correspond one-to-one with the number of material guide channels.

[0024] In the aforementioned engraving and milling machine, the material transfer component includes a movable chuck and a fixed chuck. The fixed chuck includes a main body with a horizontal top surface and a clamping part connected to one end of the main body. The movable chuck is slidably connected to the main body. The fixed chuck is also equipped with a drive source three that can drive the movable chuck to move laterally back and forth along the work platform. When the drive source three drives the movable chuck toward the fixed chuck, the robot arm closes, thereby clamping the workpiece. The horizontal top surface of the main body of the fixed chuck provides stable support for the workpiece, improving the stability of the robot arm when clamping the workpiece. At the same time, the support surface ensures that the position of the workpiece on the robot arm is fixed. Thus, when the robot arm transfers the workpiece to the workpiece clamping mechanism, it ensures a high degree of concentricity between the workpiece and the center and turntable of the workpiece clamping mechanism, thereby ensuring the processing accuracy of the engraving and milling machine.

[0025] In the aforementioned engraving and milling machine, the workpiece clamping mechanism includes a fixed crossbeam fixed to the work platform and a movable crossbeam slidably connected to the work platform along its longitudinal direction. Both the fixed and movable crossbeams are located on the upper part of the work platform and are arranged opposite each other along its longitudinal direction. A center is provided above each guide channel on the fixed crossbeam, and a turntable is provided above each guide channel on the movable crossbeam. The movable crossbeam and the conveying assembly form the workpiece input port, and the fixed crossbeam and the conveying assembly form the workpiece output port. Under the action of the material transfer component, the workpiece can be lifted between the fixed and movable crossbeams and clamped by the center and turntable on the same axial direction, achieving stable workpiece clamping. Because the movable crossbeam is slidably connected to the work platform along its longitudinal direction, its position can be adjusted according to the length of different workpieces, enabling the engraving and milling machine to process workpieces of different lengths and possessing strong versatility. A set of center and turntable is provided above each guide channel, allowing the engraving and milling machine to process multiple workpieces at a time, improving processing efficiency.

[0026] Compared with existing technologies, this engraving and milling machine has the following advantages:

[0027] 1. Relying on the drive structure, the first guide component and the second guide component are moved laterally along the working platform respectively. The width of the guide channel can be adjusted, so that this engraving and milling machine can be used for workpieces of different widths and sizes, and has strong versatility.

[0028] 2. This engraving and milling machine is equipped with multiple sets of first and second guide components on the working platform, and has multiple processing stations, which gives the engraving and milling machine the advantage of high processing efficiency.

[0029] 3. Since each guide channel has a front support, when the workpiece is conveyed forward in each guide channel, it can be positioned in the preset position by relying on each front support. Therefore, there are no special requirements for the placement time and sequence of the workpiece, making the engraving and milling machine flexible and convenient to use.

[0044] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments.

[0045] Example 1

[0046] like Figure 1 As shown, this engraving and milling machine includes a frame 1 with a working platform 1a and a workpiece clamping mechanism set on the working platform 1a of the frame 1. The frame 1 is provided with an engraving component 19 that can engrave the workpiece on the workpiece clamping mechanism. The working platform 1a of the frame 1 is also provided with a conveying component that can support the workpiece. The conveying component drives the workpiece to be horizontally conveyed along the longitudinal direction of the working platform 1a.

[0047] Combination Figure 2 , Figure 3 and Figure 4As shown, the frame 1 is also equipped with a transfer component 2 that can transfer workpieces from the conveying assembly to the workpiece clamping mechanism. The transfer component 2 is a robotic arm that can move up and down. Of course, the transfer component 2 can also be a pallet structure. Four sets of first guide components 3 and second guide components 4 are arranged in sequence along the transverse direction on the working platform 1a. The first guide components 3 and second guide components 4 are both straight strips and are both located on the upper part of the conveying assembly. The length direction of the first guide components 3 and second guide components 4 extends along the conveying direction of the conveying assembly. A narrow guide channel 5 located on the upper part of the conveying assembly is formed between the first guide components 3 and second guide components 4 in each set. The guide channel 5 also extends along the conveying direction of the conveying assembly. Below each guide channel 5, there are two transfer components 2 arranged at intervals along the longitudinal direction of the working platform 1a. The frame 1 is also equipped with a drive structure that can drive the first guide 3 and the second guide 4 to move horizontally back and forth along the conveying direction perpendicular to the conveying assembly. After the transfer member 2 moves upward, it can extend between the first guide 3 and the second guide 4. After the transfer member 2 retracts downward, the first guide 3 and the second guide 4 are reset under the action of the drive structure.

[0048] Combination Figure 2 and Figure 5 As shown, each guide channel 5 is also equipped with a movable front support 7 below it. The front support 7 is moved up and down by a cylinder. Of course, a hydraulic cylinder, a motor screw mechanism, a gear and rack mechanism, or a belt drive mechanism can also be used to drive the front support 7 to rise and fall. The front support 7 is located in front of the transfer member 2 at the foremost end of the corresponding guide channel 5. All feeding rollers 6 are set at the same height, and after the transfer member 2 and the front support 7 move downward, the top surfaces of the transfer member 2 and the front support 7 are lower than or flush with the upper edge of the feeding roller 6. By setting the front support 7, the forward travel of the workpiece can be limited, and each time the workpiece is conveyed above the transfer member 2, it can be accurately positioned in the preset position, ensuring that the transfer member 2 can act on the workpiece in the same position each time, thereby improving the processing accuracy. Below each material guide channel 5 is a guide rail 13 extending longitudinally along the working platform 1a. Two material transfer components 2 below each material guide channel 5 are slidably connected to the guide rail 13 via sliding seats 14. Between each pair of adjacent feeding rollers 6 located above the guide rail 13, there is a gap allowing the material transfer component 2 to pass upwards. By setting the guide rail 13, the distance between the two material transfer components 2 can be adjusted according to workpieces of different lengths, allowing the two material transfer components 2 to act on the workpiece in an optimal position, improving the stability of the workpiece transfer process, and thus making the automatic feeding process of the engraving and milling machine stable and reliable.

[0049] like Figure 2As shown, the conveying assembly includes several feeding rollers 6 arranged longitudinally and at intervals along the working platform 1a. The length direction of each feeding roller 6 is arranged laterally along the working platform 1a. A drive mechanism is provided on the working platform 1a to drive each feeding roller 6 to rotate synchronously. Alternatively, some of the feeding rollers 6 can rotate actively, while the remaining feeding rollers 6 do not have the power to rotate actively and only rotate passively. The workpiece clamping mechanism includes a fixed crossbeam 15 fixed on the working platform 1a and a movable crossbeam 16 slidably connected to the working platform 1a along its longitudinal direction. Both the fixed crossbeam 15 and the movable crossbeam 16 are located on the upper part of the working platform 1a and are arranged opposite each other along its longitudinal direction. A center point 17 is provided on the fixed crossbeam 15 above each guide channel 5, and a turntable 27 is provided on the movable crossbeam 16 above each guide channel 5. The movable crossbeam 16 and the conveying assembly form the workpiece input port, and the fixed crossbeam 15 and the conveying assembly form the workpiece output port. To increase the stability of the movement of the movable crossbeam 16, the movable crossbeam 16 is slidably mounted on the work platform 1a via guide rails. Alternatively, the movable crossbeam 16 can be slidably connected to the work platform 1a via a sliding block structure. In this way, the position of the movable crossbeam 16 can be manually adjusted, and after adjustment, it can be fixed using positioning components such as bolts and pins to maintain the adjusted position.

[0050] like Figure 6 and Figure 7As shown, a front mounting beam 1b is provided on the upper part of the front end of the working platform 1a, and a rear mounting beam 1c is provided on the upper part of the rear end of the working platform 1a. The front ends of each first guide member 3 and each second guide member 4 are slidably connected to the front mounting beam 1b, and the rear ends of each first guide member 3 and each second guide member 4 are slidably connected to the rear mounting beam 1c. The drive structure includes a first linkage bar 9 connected to each first guide member 3 and a second linkage bar 10 connected to each second guide member 4. The frame 1 is also provided with a drive source 11 that can drive the first linkage bar 9 to move horizontally and a drive source 2 12 that can drive the second linkage bar 10 to move horizontally and laterally. Both drive source 11 and drive source 2 12 are motors, and a lead screw is connected to the shaft of the motor. Screw sleeves that are threadedly connected to the corresponding lead screw are respectively provided on the first linkage bar 9 and the second linkage bar 10. Of course, the drive source 11 and drive source 22 can also use hydraulic cylinders, pneumatic cylinders, gear and rack mechanisms or belt drives to drive the first linkage bar 9 and the second linkage bar 10 to move. Specifically, a first linkage bar 9 and a second linkage bar 10 are slidably arranged on the front mounting beam 1b and the rear mounting beam 1c. Each first linkage bar 9 is connected to drive source 11 and each second linkage bar 10 is connected to drive source 2 12. The front end of each first guide member 3 is connected to the first linkage bar 9 on the front mounting beam 1b, the front end of each second guide member 4 is connected to the second linkage bar 10 on the front mounting beam 1b, the rear end of each first guide member 3 is connected to the first linkage bar 9 on the rear mounting beam 1c, and the rear end of each second guide member 4 is connected to the second linkage bar 10 on the rear mounting beam 1c. Because the first guide component 3 and the second guide component 4 are relatively long, the design allows both ends of the first guide component 3 and the second guide component 4 to move under the action of the drive source 11, making it less likely for the first guide component 3 and the second guide component 4 to tilt or bend during movement, thus providing better guidance for the workpiece.

[0051] like Figure 8As shown, the material handling component 2 includes a mounting plate 21, a movable chuck 23, and a fixed chuck 22 fixed to the upper end of the mounting plate 21. The mounting plate 21 has a vertically arranged slide rail, and a sliding block 14 is provided with a slider that cooperates with the slide rail. A drive source 20 is connected to the slider. The drive source 20 is a cylinder, and the piston rod of the cylinder is fixedly connected to the mounting plate 21 or the fixed chuck 22. The fixed chuck 22 includes a main body 221 with a horizontal top surface and a clamping part 222 connected to one end of the main body 221. The movable chuck 23 is slidably connected to the main body 221. The fixed chuck 22 is also provided with a drive source 24 that can drive the movable chuck 23 to move back and forth laterally along the working platform 1a. When the drive source 24 drives the movable chuck 23 to move toward the fixed chuck 22, the robot closes, thereby clamping the workpiece. The top surface of the main body 221 of the fixed chuck 22 is horizontal, which allows the top surface of the main body 221 to provide stable support for the workpiece, improving the stability of the robot arm when holding the workpiece and ensuring the machining accuracy of the engraving and milling machine. Of course, the drive source 4 20 and drive source 3 24 can also be hydraulic cylinders, gear rack mechanisms, or motor screw mechanisms, etc.

[0052] The working principle of this engraving and milling machine is briefly described below: This engraving and milling machine is mainly used for processing strip-shaped workpieces. During processing, the workpiece is first placed in the guide channel 5, so that the length direction of the workpiece is consistent with the length direction of the guide channel 5. The workpiece is conveyed forward under the action of the conveying component. When the workpiece passes through the workpiece input port and reaches the top of the transfer component 2, the front end of the workpiece is blocked by the front support 7, and the workpiece stops. Then, the drive structure drives the first guide component 3 and the second guide component 4 to move away from the workpiece, so that the distance between the first guide component 3 and the second guide component 4 increases, thus avoiding the transfer component 2. Then, the transfer component 2 moves upward and clamps the workpiece in the feed channel. After clamping, the transfer component 2 continues to drive the workpiece upward until the two end faces of the workpiece are opposite the center 17 and the turntable 27 on the same axis. The center 17 and the turntable 27 are brought close together to clamp the workpiece. Finally, the engraving component 19 of the CNC engraving machine processes the workpiece. Simultaneously, the transfer component 2 retracts downwards to its original position. After the transfer component 2 retracts, the first guide component 3 and the second guide component 4 also reset under the action of the drive structure, completing one loading process. After the workpiece is processed, the unloading process begins. The unloading process can be achieved by the transfer component 2 moving the workpiece downwards from between the center point 17 and the turntable 27 onto the conveying component. Alternatively, the workpiece can be released from between the center point 17 and the turntable 27, allowing it to fall directly onto the conveying component. After the workpiece is unloaded onto the conveying component, the conveying component drives the workpiece out of its output port.
