Description

Technical Field

[0001] This invention relates to the fields of customized home furnishing production and processing, and panel carving technology, specifically to an automated carving machine for customized home furnishing panels. Background Technology

[0002] With the continuous development of technology and the improvement of people's living standards, the demand for customized home furnishing products is increasing due to their advantages in rational and efficient space utilization, as well as their aesthetic appeal and environmental friendliness. In the production process of customized home furnishing products, engraving patterns onto customized boards to create aesthetically pleasing and practical cabinet doors and panels is an essential step. However, current technology typically uses clamping tools and PLC-driven control to perform the engraving operation on customized boards.

[0003] However, traditional sheet metal clamping tools, while simple in structure, have poor clamping effect and can be roughly divided into three categories: The first category uses bilateral symmetrical top pressure clamping. This type of clamping tool is particularly common in actual sheet metal processing operations. Its structure is very simple, using a single air cylinder or hydraulic cylinder to achieve driving compression. However, this method can only position the sheet metal in the left and right directions, and cannot achieve vertical positioning—the top of the sheet metal (positioning in the bottom direction of the sheet metal is provided by the support surface). Of course, the conventional operation is to increase the pre-tightening force in the left and right directions of the sheet metal, but this method of increasing the pre-tightening force will disrupt the overall balance of the sheet metal. Excessive force will cause the sheet metal to "arch", resulting in product damage and reduced quality.

[0004] The second type uses a bilaterally symmetrical "C"-shaped fixture for positioning and fastening. The advantage of this method is that it provides positioning in all four directions of the board, and the pre-tightening force can be balanced. However, the disadvantage is also obvious: due to the positioning support of the bottom fixture, the bottom surface of the board lacks substantial support, forming a hollow structure. When the engraving machine carries the cutting tool to engrave patterns on the board, there is downward pressure on the board. Thicker boards are less affected by this downward pressure, but boards of average or less thickness, under the influence of this downward pressure and the continuous pressure from the pre-tightening force on both sides, tend to bulge outwards. This significantly reduces product quality and seriously affects the lifespan of custom-made furniture products assembled from custom boards.

[0005] The third type uses positioning on the upper or lower surface of the board (using negative pressure adsorption) combined with positioning assistance in the left and right directions. This method has significant advantages over the first and second types, as it ensures pre-tightening forces are applied to the board in all directions. However, this type of fixture is structurally complex, expensive, and not cost-effective, resulting in only average board clamping performance. In summary, traditional board clamping fixtures all suffer from poor clamping performance, especially in actual board pattern engraving operations where double-sided engraving is frequently encountered. Traditional fixtures still require unlocking the board's positioning and manual flipping, which is time-consuming and labor-intensive. They cannot achieve convenient and automated double-sided flipping engraving while maintaining good positioning and clamping performance, significantly reducing the efficiency of board engraving operations. Therefore, we need an automated engraving machine for custom-made home furnishing boards. Summary of the Invention

[0006] In order to address the shortcomings and deficiencies of existing custom panel carving and fastening fixtures, this invention provides an automated carving machine for custom home panels.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An automated engraving machine for custom-made home furnishing panels includes a mounting frame, an engraving device, and tooling fixtures;

[0009] The mounting frame includes a support plate, support pads, and a mounting plate; the support plate is distributed left and right, and there are multiple support pads, which are rotatably disposed at the lower end of the support plate; there are two mounting plates that are symmetrically distributed left and right and are disposed at both ends of the support plate front and back, and the mounting plates are hollow structures, with through grooves on opposite sides.

[0010] The engraving device includes a carrier and an engraving machine mounted on the carrier; the engraving machine is vertically distributed and carries an engraving knife at its output end; the carrier is also vertically distributed and is mounted on a mounting plate via a drive mechanism, so that the engraving machine can perform multi-dimensional movements in the left, right and forward and backward directions as well as lifting and lowering.

[0011] The tooling fixture consists of two sets arranged symmetrically on the left and right. Each set of the tooling fixture further includes a drive source, a connecting arm, a pressure plate, and a pre-tightening device. The drive source is located inside the mounting plate cavity, and its output shaft passes through the through slot and connects to the connecting arm, enabling the pre-tightening device to move along the mounting plate to a preset position and complete a 180-degree flipping motion. The connecting arms are distributed on the left and right sides and are located at the center of the pressure plate. The pressure plate is distributed front and back. The drive source can also drive the connecting arms and the pressure plate as a whole to move up and down and left and right.

[0012] The pre-tightening device further includes a fastening plate, a clamping plate, and a fastening component; the fastening plate has a T-shaped structure and a mounting hole extending vertically at its center, and a mounting groove on the side of the fastening plate near the pressure plate, which communicates with the mounting hole; there are two clamping plates, symmetrically distributed in the mounting hole; the center point of the clamping plate is not on the central axis of the mounting hole, and in the initial state, the side of the clamping plate near the plate is flush with the side of the fastening plate, and the central axis of the connecting arm coincides with the vertical center point of the fastening component; the fastening component is configured such that when the connecting arm moves down, the upper clamping plate moves up to a preset position and rotates 180 degrees to form a clamping operation on the plate.

[0013] As a preferred technical solution, the driving source includes a driving arm, a driving screw, a driving motor, and a tilting motor; a sliding groove is provided on one side of the mounting plate; the driving arm has a T-shaped structure and is adapted to be installed in the sliding groove, and the driving arm is also provided with a connecting hole that runs through the front and rear; the driving screw is rotatably and immovably mounted on the mounting plate, the driving screw is distributed front and rear and passes through the connecting hole so that the driving arm can move back and forth; the driving motor is located on the rear side wall of the mounting plate, and its output shaft is connected to the driving screw; the tilting motor is located on the driving arm, and its output shaft is distributed left and right.

[0015] A further preferred technical solution is that the fastening component includes an adjusting plate, an adjusting column, and an adjusting structure; the adjusting plate is horizontally arranged and distributed left and right, with one end connected to the pressure plate and the other end sleeved and installed on the adjusting column, maintaining its vertical movement along the mounting groove; the adjusting column is coaxially arranged in the mounting hole, and from the midpoint to the end, it consists of a threaded part, a connecting part, and a flipping part, with the outer diameters of the three parts gradually decreasing; in the initial state, the adjusting plate is at the midpoint of the adjusting column; the adjusting structure is used to drive the clamping plate to move up and down and flip.

[0016] In a further preferred embodiment, the adjustment structure comprises two symmetrically arranged sets, each set including a threaded sleeve and a flip sleeve. The threaded sleeve has a T-shaped cross-section and is centrally fitted onto the adjustment column. Its outer wall is rotatably connected to the side wall of the mounting hole via a thread. A washer is provided at the shoulder of the threaded portion and the connecting portion to allow the adjustment column to rotate but not move relative to it. The flip sleeve is movably disposed on the outside of the fastening plate and is coaxially arranged with the adjustment column. The outer edge of the flip sleeve is fastened to the clamping plate by bolts, forming an integral structure. The shoulder of the threaded sleeve is located inside the flip sleeve, and a first torsion spring is provided between them.

[0017] In a further preferred embodiment, a connecting block is provided at the shoulder of the connecting part and the flipping part. The connecting block is annular, and its outer side wall and the inner side wall of the screw sleeve are movable relative to each other but not rotate relative to each other. A second torsion spring is provided in the connecting block so that the adjusting column can rotate counterclockwise, thereby driving the screw sleeve to rotate and rise.

[0018] A further preferred technical solution is that a rotating sleeve with a shoulder is provided inside the flip sleeve. The rotating sleeve is fitted and installed on the flip part of the adjusting column and is located in the vertical outer direction of the connecting block. The outer end of the rotating sleeve is connected by an end cap and keeps the rotating sleeve rotating synchronously with the adjusting column. The outer side of the rotating sleeve maintains sliding contact with the inner side of the threaded sleeve.

[0019] A further preferred technical solution is that a flipping block and a third torsion spring are provided at the shoulder of the rotating sleeve; the third torsion spring is sleeved and installed on the rotating sleeve, with its inner end connected to the rotating sleeve and its outer end connected to the flipping block, and the flipping block and the flipping sleeve are kept in a state of relative sliding but not relative rotation.

[0020] As a preferred technical solution, the driving mechanism includes a first driving component and a second driving component; there are two first driving components, which are symmetrically distributed on the mounting plate; and the first driving component includes a first driving plate, a first lead screw, a first slider, a first slide rail, and a first servo motor; the first driving plate is disposed on the mounting plate; the first lead screw is disposed on the right side of the first driving plate, and its two ends are rotatably connected to the side wall of the first driving plate; the first slider is movably disposed on the first lead screw; the first slide rail is disposed on the left side of the first driving plate; and the output shaft of the first servo motor is connected to the first lead screw.

[0021] A further preferred technical solution includes a second driving component comprising a second driving plate, a second lead screw, a second slider, guide blocks, guide plates, and a hydraulic push rod. The second driving plate has a concave structure, and the bottom ends of its two side walls are slidably connected to the first slide rail. The second driving plate is also fixedly connected to the first slider. The second lead screw is rotatably mounted on the second driving plate, with one end connected to a second servo motor. The second slider is mounted on the carrier and fitted onto the second lead screw, moving with the rotation of the second lead screw. There are two guide blocks, both mounted on the carrier and located on the upper and lower sides of the second slider. There are two guide plates, rotatably mounted on the second driving plate and located on the upper and lower sides of the second lead screw. The guide blocks are slidably mounted on the guide plates. The hydraulic push rod is positioned between the carrier and the engraving machine to enable the engraving machine to perform lifting and lowering movements.

[0022] The advantages of this invention compared to existing technologies are: the overall structure of the engraving machine is more rationally designed. The drive mechanism enables the engraving machine to move in multiple directions (left, right, forward, backward), and uses a hydraulic push rod within the drive mechanism to raise and lower the engraving machine, completing the pattern engraving operation. Simultaneously, a special drive source component is used, which not only moves the pre-tightening device and the entire sheet material along the mounting plate to a preset position (outside the mounting frame) and completes a 180-degree rotation, but also moves the connecting arm and pressure plate vertically and horizontally. The horizontal movement is for clamping the sheet material and completing the positioning and pre-tightening; the vertical movement is for driving the pre-tightening device to complete the vertical positioning and clamping of the sheet material. This allows for rapid pattern engraving without detaching the sheet material, regardless of whether the pattern is being engraved on the top or bottom surface. In other words, the pre-tightening device performs a single-stage clamping operation on the sheet material, easily completing double-sided pattern engraving on customized sheets, greatly improving the efficiency of customized sheet engraving operations.

[0023] This further enables convenient and automated double-sided engraving of customized boards while ensuring good positioning and fastening, making it more practical. Attached Figure Description

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] It should be noted that, in specific embodiments of the present invention, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any actual relationship or order between these entities or operations. Furthermore, terms such as "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, the use of phrases such as "comprising a..." to define an element does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0045] In the description of this invention, unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," and "equipped" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0046] Example 1: As Figures 1-11 As shown:

[0047] An automated engraving machine for custom-made home furnishing panels includes a mounting frame 1, an engraving device 2, and a tooling fixture 3. The overall structure of this engraving machine is more rationally designed. Whether the pattern engraving is performed on the upper or lower surface of the panel, it can be completed quickly without detaching the panel from its fixed position, completely eliminating the need for disassembly and re-clamping.

[0048] Among them, such as Figure 1 As shown: Mounting frame 1 includes a support plate 11, support pads 12, and mounting plate 13. The support plate 11 is distributed left and right, and there are multiple support pads 12, which are rotatably set at the lower end of the support plate 11. The support pads are used to achieve the stability of the engraving machine by using screws and screw grooves. There are two mounting plates 13, which are symmetrically distributed left and right and are arranged front and back at both ends of the support plate 11. The mounting plate 13 has a hollow structure, and each side has a through groove 14; the through groove 14 communicates with the inner cavity of the mounting plate 13. The purpose of this arrangement is to facilitate the installation of the drive source component, make reasonable use of space, and enable subsequent engraving processing on the reverse side of the material. The process can continue without interruption, without manual operation, saving time and labor, and achieving a higher degree of automation.

[0049] In this embodiment, as Figure 1 As shown: The engraving device 2 includes a carrier 21 and an engraving machine 22 mounted on the carrier 21. The engraving machine 22 is vertically positioned and carries an engraving blade at its output end, facilitating pattern processing. The carrier 21 is also vertically positioned and is mounted on the mounting plate 13 via a drive mechanism 23, enabling the engraving machine 22 to perform multi-dimensional movements in left-right, forward-backward, and vertical directions, as well as lifting movements. The drive mechanism can employ a combination of existing technologies such as servo motors, cylinders, hydraulic cylinders, and electric lifting rods. The specific structure of the drive mechanism 23 will not be described in detail here.

[0050] like Figure 2 As shown: The tooling fixtures 3 are arranged in two symmetrical sets, each set including a drive source 31, a connecting arm 32, a pressure plate 33, and a pre-tightening device 34. The drive source 31 is located inside the mounting plate 13, and its output shaft passes through the through slot 14 and connects to the connecting arm 32, enabling it to move the pre-tightening device 34 along the mounting plate 13 to a preset position and complete a 180-degree rotation. The connecting arms 32 are distributed left and right, and are located at the center of the pressure plate 33, which is distributed front and back. The drive source 31 can also drive the connecting arms 32 and the pressure plate 33 to move up and down and left and right as a whole.

[0051] In this embodiment, as Figure 11As shown: The drive source 31 includes a drive arm 41, a drive screw 42, a drive motor 44, and a tilting motor 45. An axially distributed groove 46 is provided on one side of the mounting plate 13. The drive arm 41 has a T-shaped structure and is fitted into the groove 46. A connecting hole 43, passing through the front and rear of the drive arm 41, is also provided on the drive arm 41. The drive screw 42 is rotatably but immovably mounted on the front and rear side walls of the mounting plate 13. The drive screw 42 is distributed front to back and passes through the connecting hole 43, and the two are threaded together, so that the rotation of the drive screw drives the drive arm 41 to move back and forth. The purpose of this arrangement is to move the material to the outside first, and then flip it over to perform pattern engraving on the other side of the material. The drive motor 44 is located on the rear side wall of the mounting plate 13, and its output shaft is connected to the drive screw 42. The tilting motor 45 is located on the drive arm 41, and its output shaft is distributed left to right.

[0052] like Figure 11 As shown: In this embodiment, the drive source 31 further includes a first hydraulic cylinder 47, a second hydraulic cylinder 48, and an auxiliary frame 49. The first hydraulic cylinder 47 is located at the lower end of the drive arm 41, and its lower output shaft is connected to a motor sleeve 410 via a fastening bolt. The tilting motor 45 is mounted inside the motor sleeve 410 via a bracket. The output shaft of the second hydraulic cylinder 48 is connected to the connecting arm 32, and its other side is connected to the output shaft of the tilting motor 45. The motor sleeve 410 also has an annular groove 411 on one side near the plate. The auxiliary frame 49 consists of three auxiliary rods, which are L-shaped. One end of each rod is fixedly connected to the second hydraulic cylinder 48, and the other end can rotate along the annular groove 411. The purpose of this arrangement is to facilitate the tilting operation of the plate while ensuring stability, based on the pre-tightening of the pressure plate driven by the second hydraulic cylinder itself.

[0053] In this embodiment, as Figure 3 As shown: The pre-tightening device 34 also includes a fastening plate 341, a clamping plate 342, and a fastening element 343. For example... Figure 8 As shown: The horizontal cross-section of the fastening plate 341 is T-shaped, and a through-hole 344 is provided at the center. The fastening plate 341 also has a mounting groove 345 on the side near the pressure plate 33, which communicates with the mounting hole 344. Two clamping plates 342 are symmetrically distributed at both ends of the mounting hole 344. The center point of the clamping plate 342 is not on the central axis of the mounting hole 344, i.e., it is eccentrically positioned. Initially, the side of the clamping plate 342 near the plate is flush with the side of the fastening plate 341, and the central axis of the connecting arm 32 coincides with the vertical center point of the fastening member 343. This ensures a good fastening effect. When the fastening member 343 is configured such that the connecting arm 32 moves downward, the upper clamping plate 342 moves upward to a preset position and rotates 180 degrees to clamp the plate.

[0054] In this embodiment, as Figure 5As shown: The fastening component 343 includes an adjusting plate 51, an adjusting column 52, and an adjusting structure 53. The adjusting plate 51 is horizontally arranged and distributed left and right. One end is connected to the pressure plate 33, and the other end is sleeved and installed on the adjusting column 52. Rotation of the adjusting column 52 will cause the adjusting plate to move up and down along the mounting groove 345. The adjusting column 52 is coaxially arranged in the mounting hole 344. The adjusting column consists of two symmetrical parts; and from the midpoint to the end, the parts are arranged in sequence as a threaded part 521, a connecting part 522, and a flipping part 523, with the outer diameter of the three parts gradually decreasing. In the initial state, the adjusting plate 51 is at the midpoint of the adjusting column 52, as shown... Figure 5 .

[0055] like Figure 5 As shown: Adjustment structure 53 is used to drive the clamping plate 342 to move up and down and flip. In this embodiment, the adjustment structure 53 consists of two sets arranged symmetrically up and down. Each set of adjustment structure 53 also includes a threaded sleeve 61 and a flipping sleeve 62. The threaded sleeve 61 has a T-shaped cross-section and is centrally fitted onto the adjustment column 52. Its outer wall is rotatably connected to the side wall of the mounting hole 344 via a thread. A washer 63 is also provided at the shoulder of the threaded part 521 and the connecting part 522 to allow the adjustment column 52 to rotate but not move relative to it. The flipping sleeve 62 is movably disposed on the outside of the fastening plate 341 and is coaxially disposed with the adjustment column 52. The outer edge of the flipping sleeve 62 is fastened to the clamping plate 342 by bolts, and the two form an integral structure; as shown Figure 6 As shown. The shoulder of the threaded sleeve 61 is located inside the flip sleeve 62, and a first torsion spring 64 is provided between the two. The first torsion spring 64 can store force to provide power for the flipping action after the card is unlocked.

[0056] In this embodiment, as Figure 7 As shown: A connecting block 65 is also provided at the shoulder of the connecting part 522 and the flipping part 523. The connecting block 65 is annular, and its outer wall is movable relative to the inner wall of the threaded sleeve 61 but not rotatable relative to it. Specifically, it can be achieved by setting a key shaft in the connecting block and a keyway in the inner wall of the threaded sleeve. A second torsion spring 66 is provided inside the connecting block 65 so that when the adjusting column 52 rotates counterclockwise, it can drive the threaded sleeve 61 to rotate and rise. Figure 9 As shown. The purpose of this design is to facilitate the up-and-down movement of the screw sleeve while providing a reasonable buffer time so that the adjusting column rotates first, and then drives the screw sleeve from zero speed to match the speed of the adjusting column, thereby ensuring smooth subsequent flipping action.

[0057] Among them, such as Figure 9As shown: A rotating sleeve 67 with a shoulder is also provided inside the flip sleeve 62. The rotating sleeve 67 is fitted and installed on the flip part 523 of the adjusting column 52, and is located in the vertical outer direction of the connecting block 65. The outer end of the rotating sleeve 67 is connected by an end cap 68, which keeps the rotating sleeve 67 rotating synchronously with the adjusting column 52. The outer surface of the rotating sleeve 67 maintains sliding contact with the inner surface of the threaded sleeve 61. The rotating sleeve and the adjusting column are integrated, which facilitates the smooth placement and positioning of the unit during the assembly stage.

[0058] In this embodiment, as Figure 10 As shown: A flipping block 69 and a third torsion spring 610 are also provided at the shoulder of the rotating sleeve 67. The third torsion spring 610 is sleeved and installed on the rotating sleeve 67, with its inner end connected to the rotating sleeve 67 and its outer end connected to the flipping block 69. The flipping block 69 and the flipping sleeve 62 are allowed to slide relative to each other but cannot rotate relative to each other. Specifically, this can be achieved by setting a key shaft in the flipping block and a keyway in the inner wall of the flipping sleeve. The third torsion spring can store force, and when the clamping plate rises and moves to a state without resistance, it instantly unlocks and clamps the plate. The preload of the third torsion spring 610 and the second torsion spring 66 are both greater than the maximum elastic force that the first torsion spring 64 can achieve during the entire working process, ensuring normal operation.

[0059] The working principle of an automated engraving machine for custom-made home furnishing panels:

[0060] First, during the preparation stage of the engraving machine 22, the operator uses external auxiliary equipment to place the customized material to be processed onto the upper surface of the support plate 11. Initially, the side of the clamping plate 342 closest to the material is flush with the side of the fastening plate 341. The central axis of the connecting arm 32 coincides with the vertical center point of the fastening component 343. Figure 5 As shown.

[0061] The operator starts the drive motor 44, which is a servo motor. The advantages of a servo motor include: excellent speed control characteristics, smooth control across the entire speed range with virtually no oscillation, high efficiency (over 90%), no heat generation, high-speed control, and high-precision position control. The rotation of the drive motor 44 drives the drive screw 42 to rotate synchronously, which in turn moves the drive arm 41 on the drive screw 42 until multiple fasteners 343 on the pressure plate 33 are positioned on the side of the plate. Then, the operator activates the second hydraulic cylinder 48, which extends its hydraulic arm, causing the connecting arm 32, pressure plate 33, and fasteners 343 to move towards the plate. This continues until the sides of the fasteners 341 and clamping plates 342 are pressed against the plate with a preset pre-tension force. At this point, all the fasteners 341 distributed on the pressure plate 33 remain in contact with the plate; the state of each individual fastener 343 is as follows: Figure 4As shown. The plate has been positioned and secured in the left and right directions, and is supported by the support plate 11 in the vertical-down direction.

[0062] Then, the operator activates the first hydraulic cylinder 47, which extends the hydraulic arm, causing the second hydraulic cylinder 48, pressure plate 33, and adjusting plate 51 mounted on pressure plate 33 to move downwards. The downward movement of adjusting plate 51 causes adjusting column 52 to rotate counterclockwise. This rotation of adjusting column 52 causes the second torsion spring 66 to change position, transmitting force. Consequently, connecting block 65, connected to the second torsion spring 66, also rotates synchronously with adjusting column 52. The relationship between connecting block 65 and threaded sleeve 61 is one of relative movement but not relative rotation. Therefore, connecting block 65 causes threaded sleeve 61 to rotate, and the rotation of threaded sleeve 61 causes it to move upwards relative to fixing plate 341, specifically as follows... Figure 9 As shown. Meanwhile, the threaded sleeve 61 and the flip sleeve 62 are connected by the first torsion spring 64. However, at this time, the integrated structure of the flip sleeve 62 and the clamping plate 342 is still blocked by the plate on the right side, therefore... Figure 9 As shown, the locking plate 342 is not unlocked. At this time, due to the rotation of the screw sleeve 61, on the one hand, it will drive the flip sleeve 62 to move upward, and on the other hand, the flip sleeve 62 will remain stationary, causing the first torsion spring 64 to continue to store force.

[0063] Meanwhile, since the rotating sleeve 67 and the adjusting column 52 are integrated, they rotate synchronously. Furthermore, because the flip sleeve 62 remains stationary when blocked by the clamping plate 342, the flip sleeve 62 and the flip block 69 maintain a relative movable but non-rotatable relationship. Therefore, the rotation of the rotating sleeve 67 causes the third torsion spring 610 to continuously store force until the threaded sleeve 61 moves upward to the preset position, such as... Figure 10 As shown. At this time, the clamping plate 342 is no longer blocked by the plate on the right, and the clamping plate 342 will rotate 180 degrees instantly (this can be achieved by controlling the downward pressing distance of the adjusting plate 51 and coordinating the preset number of rotations of the adjusting column 52). In this way, the clamping plate 342 can be unlocked, and the vertical positioning and clamping of the plate can be completed. Therefore, the tooling fixture 3 of the engraving machine 22 has completed the positioning and fastening of the plate in four directions: left, right, up, and down. During this process, the lower clamping plate is blocked by the side plate and pressed by the bottom support plate, so the lower adjustment structure does not shift or deflect, and the torsion spring only stores force.

[0064] After the pattern engraving operation is completed on the upper surface of the customized board with the cooperation of the drive mechanism 23 and the PLC controller, and the board needs to be flipped to process the other side, the first hydraulic cylinder 47 begins to retract, which in turn drives the adjusting plate 51 to move upward. At this time, the adjusting column 52 will rotate clockwise. This will then drive the flipping block 69 to rotate synchronously, and the flipping block 69 will drive the flipping sleeve 62 and the clamping plate 342 to rotate and reset. The first hydraulic cylinder 47 continues to retract, and the adjusting plate 51 continues to move upward to the initial state until the fastener 343 is completely reset. Then the operator starts the drive motor 44, which drives the drive arm 41 to move outward until it moves the tooling fixture 3 and the board to the preset position.

[0065] The rotating motor 45 is then activated, causing the tooling fixture 3 and the entire board to rotate 180 degrees. The operator then activates the drive motor 44 in reverse, moving the drive arm 41 inward to its initial position. Repeating this process completes the positioning and clamping of the board's "upper surface" (the original lower surface). This achieves convenient and automated double-sided rotating engraving on customized boards while ensuring good positioning and securing, making it more practical and significantly improving the board processing efficiency of the automated engraving machine 22; it also ensures the quality of the engraved pattern on the board.

[0066] Example 2: Figure 12 As shown: Based on Embodiment 1, an automated engraving machine for custom-made home furnishing panels preferably employs a drive mechanism comprising a first drive component 71 and a second drive component 72. There are two first drive components 71, symmetrically distributed on the mounting plate. Each first drive component 71 includes a first drive plate 711, a first lead screw 712, a first slider 713, a first slide rail 714, and a first servo motor 715. The first drive plate 711 is mounted on the mounting plate. The first lead screw is located on the right side of the first drive plate 711, and its two ends are rotatably connected to the sidewalls of the first drive plate 711. The first slider 713 is movably mounted on the first lead screw 712.

[0067] The first slide rail 714 is located on the left side of the first drive plate 711; the output shaft of the first servo motor 715 is connected to the first lead screw 712. With this configuration, the rotation of the first servo motor can drive the lead screw to rotate, thereby driving the first slider to move back and forth. The first slider is connected to the second drive plate, which is integrated with the carrier and the engraving machine. Therefore, it will drive the engraving tool to move in the back and forth direction.

[0068] In this embodiment, the second driving component 72 includes a second driving plate 721, a second lead screw 722, a second slider 723, a guide block 724, a guide plate 725, and a hydraulic push rod 726. The second driving plate 721 has a concave structure, and the bottom ends of its two side walls are slidably connected to the first slide rail 714. The second driving plate 721 is also fixedly connected to the first slider 713. The second lead screw 722 is rotatably disposed on the second driving plate 721, and one end of the second lead screw 722 is connected to a second servo motor 727. The second slider 723 is disposed on the carrier 21 and sleeved on the second lead screw 722, moving with the rotation of the second lead screw 722.

[0069] Two guide blocks 724 are disposed on the carrier 21, located on the upper and lower sides of the second slider 723. Two guide plates 725 are disposed on the second drive plate 721, located on the upper and lower sides of the second lead screw 722, and the guide blocks 724 are slidably disposed on the guide plates 725. With this configuration, the rotation of the second servo motor causes the second lead screw to rotate synchronously, thereby driving the second slider to move in the left and right directions. The hydraulic push rod 726 is an electro-hydraulic push rod, disposed between the carrier and the engraving machine, enabling the engraving machine to perform lifting and lowering movements. The hydraulic push rod, the second servo motor, and the third servo motor are connected to an external PLC controller. The PLC controller can be controlled by inputting commands through simple program programming; this is existing technology for those skilled in the art and will not be described in detail here.

[0070] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
