[0002] A CNC engraving machine is a type of CNC machine tool used for grinding, cutting, and other processing of products. A CNC engraving machine typically consists of a main body and a door, with the door slidingly mounted on the main body. Various cutting heads and fixtures are mounted on the main body. Currently, most CNC engraving machines on the market use manual or robotic arm material handling. Using a robotic arm requires consideration of the arm's movement radius and occupies a significant amount of space. Manual material handling poses safety hazards, and with the implementation of intelligent workshops, traditional manual material handling methods will be phased out in the future. Therefore, this paper proposes a highly adaptable and space-saving material handling device as an auxiliary structure for the CNC engraving machine. Utility Model Content

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

[0032] Example 1

[0033] like Figures 1 to 7 As shown, the loading and unloading device of the engraving machine in this embodiment includes:

[0034] Support frame 1 is mounted on engraving machine 10; support frame 1 serves as the base of the entire loading and unloading device by being mounted on engraving machine 10. Support frame 1 includes connecting block 11, which is fixedly mounted on engraving machine 10 by bolts. The setting of support frame 1 enables the device to be stably fixed next to engraving machine and provides the necessary support height.

[0035] A transverse frame 2, mounted on the support frame 1, is bolted to the upper part of the support frame 1 and is used to support the X-axis moving module. The structural design of the transverse frame 2 should ensure sufficient rigidity and stability to support the movement of subsequent moving parts. The X-axis moving module is used to realize the movement of the device in the horizontal X direction.

[0036] A transition frame 4 is slidably mounted on the X-axis moving module. The X-axis moving module includes a first slide rail 31, which is mounted on the transverse frame 2 and provides guidance for the X-axis movement of the transition frame 4. A first slider 41 is mounted on the transition frame 4, which slides in cooperation with the first slide rail 31. The cooperation between the first slider 41 and the first slide rail 31 ensures smooth and precise movement of the transition frame 4 in the X direction. A first rack 21 is mounted on the transverse frame 2, and a first drive gear 42 is mounted on the transition frame 4, which cooperates with the first rack 21. By driving the rotation of the first drive gear 42, the transition frame 4 can be moved along the first rack 21 in the X direction, achieving precise displacement control in the X direction.

[0037] The longitudinal frame 5 is equipped with a Y-axis movement module, which is slidably connected to the transition frame 4. The Y-axis movement module includes a second slide rail 61, which is mounted on the longitudinal frame 5 and provides guidance for the Y-axis movement of the transition frame 4. The transition frame 4 is equipped with a second slider 43 that slidably engages with the second slide rail 61. The engagement of the second slider 43 and the second slide rail 61 ensures smooth and precise movement of the transition frame 4 in the Y direction. The longitudinal frame 5 is equipped with a second rack 51, and the transition frame 4 is equipped with a second drive gear 44, which engages with the second rack 51. By driving the rotation of the second drive gear 44, the transition frame 4 can be moved along the second rack 51 in the Y direction, achieving precise displacement control in the Y direction.

[0038] The Z-axis moving module is mounted on the longitudinal frame 5. The Z-axis moving module includes a slide rail 71 and a third rack 72. A third slider 52, which slides and engages with the slide rail 71, is located at one end of the longitudinal frame 5. The engagement of the third slider 52 with the slide rail 71 ensures smooth and precise movement of the Z-axis moving module 7 in the Z direction. A third drive gear 53 is mounted on the longitudinal frame 5, engaging with the third rack 72. By rotating the third drive gear 53, the Z-axis moving module can be moved along the third rack 72 in the Z direction, achieving precise displacement control in the Z direction. The drive gears mentioned above all include a drive motor (which can be a motor structure with a reducer) and a gear meshing with the rack. The drive motor drives the gear to rotate. The gear and rack here adopt a helical tooth structure (the gear meshing module and number of teeth design here are conventional technologies in this field and can use existing commercial products).

[0039] The gripper mechanism is the part that directly contacts the workpiece and is responsible for gripping and releasing it. Through the lifting of the Z-axis moving module and the movement of the X-axis and Y-axis moving modules, the gripper mechanism can pick up the workpiece from the loading area and move it to the engraving machine's processing area, or remove the processed workpiece from the engraving machine and place it in the unloading area.

[0040] The X-axis, Y-axis, and Z-axis movement modules all include limit switches 8. Limit switches 8 can be installed at the end of the stroke of each axis or at specific positions to detect whether the moving parts have reached the preset position and send signals to the control system, thereby achieving precise stroke control and preventing overshoot, ensuring stable and reliable operation of the device. Limit switches 8 here include extreme limit switches; in actual use, they also include position sensing switches to sense the operating position of each module.

[0041] A gripper mechanism is located at one end of the Z-axis moving module. The gripper mechanism is a vacuum suction cup structure. The number and distribution of suction cups in the vacuum suction cup structure are set according to the product to be processed; a diagram of the suction cup structure is not shown here. Adjusting the negative pressure suction of the vacuum suction cup structure is a conventional technique in this field; the appropriate suction force can be adjusted according to the size and weight of the material (the arrangement of the vacuum pump and piping is a conventional technique and is not detailed here). The vacuum suction cup is a conventional sheet material feeding mechanism, and the vacuum suction cup structure has the following advantages:

[0042] No damage to workpieces: Vacuum suction cups adsorb workpiece surfaces through negative pressure, without causing mechanical damage or scratches to the workpieces, making them particularly suitable for precision-machined parts or workpieces with high surface requirements.

[0043] Wide adaptability: Vacuum suction cups can adsorb workpieces of various shapes, sizes and materials, as long as the workpiece surface is relatively flat and airtight, making them highly versatile.

[0044] Stable gripping: Once a vacuum is formed, the suction cup can firmly adhere to the workpiece and is not easy to fall off during movement, ensuring the stability of loading and unloading.

[0045] Simple operation: The adsorption and release of the vacuum suction cup is usually achieved by controlling the start and stop of the vacuum pump, which is simple to control and responds quickly.

[0046] In use, the vacuum suction cup descends to contact the workpiece surface, and the vacuum pump is activated to generate negative pressure, adsorbing the workpiece. Then, the Z-axis moving module 7 rises, lifting the workpiece, and the X and Y-axis moving modules transport the workpiece to the target position. After reaching the target position, the Z-axis moving module 7 descends, placing the workpiece in place, stopping the vacuum pump or applying positive pressure to release the workpiece. This configuration of the vacuum suction cup further enhances the automation level and adaptability to different workpieces of the loading and unloading device of this invention. Under the coordinated action of the X, Y, and Z-axis moving modules, the gripper mechanism moves to the loading area to grab the workpiece to be processed; then it moves to the processing area of ​​the engraving machine 10 and places the workpiece in place; after the engraving machine finishes processing, the gripper mechanism moves back to the processing area to grab the processed workpiece; finally, the workpiece is moved to the unloading area and released. In this way, the loading and unloading of workpieces for the engraving machine is automated, significantly improving production efficiency and automation level. To ensure smooth movement, drag chains or other structures should be installed at corresponding positions.

[0047] It should be noted that this utility model also includes a placement platform with several placement positions, and a lifting mechanism at the bottom of the platform. This lifting mechanism is used to raise the placement positions, always keeping the top surface of the product at the current placement position at the same height to facilitate the use of the vacuum suction cup structure. This lifting mechanism can be one of a lead screw, hydraulic cylinder, or pneumatic cylinder. Maintaining the same height is achieved with the assistance of a position sensor (photoelectric sensor, proximity switch, etc.). When the position is reached, the lifting mechanism stops lifting. Multiple materials to be processed are placed on the placement positions (stacked). After the suction cup structure picks up the upper layer of product, the lifting mechanism lifts the lower layer of product upwards, so that the top surface of the lower layer of product is located at the suction position of the vacuum suction cup. The vacuum suction cup actually has a lifting function; the use of a lifting mechanism here reduces the positioning and adjustment of the vacuum suction cup, which is beneficial to improving efficiency.

[0048] Example 2

[0049] like Figure 8 As shown, the support frame 1 includes a connecting block 11, a fixed pipe 12, a movable pipe 13, and a telescopic drive mechanism. The fixed pipe 12 is fixedly connected to the connecting block 11, and the movable pipe 13 is slidably connected to the fixed pipe 12 (this sliding connection can be achieved using guide grooves and guide keys or slider rails; the sliding mainly restricts rotation, so two pipe structures of different dimensions and directions are sufficient to meet the requirements). One end of the telescopic drive mechanism is connected to the fixed pipe 12, and the other end is connected to the movable pipe 13. The extension length of the movable pipe 13 is adjusted through the telescopic drive mechanism. The upper end of the movable pipe 13 is connected to the transverse frame 2. The telescopic drive mechanism can be a combination of a screw motor, a hydraulic cylinder, or a pneumatic cylinder to adjust the extension length of the movable pipe 13. This design allows the height of the entire loading and unloading device to be flexibly adjusted according to the actual working height of the engraving machine 10 or the size of the workpiece, enhancing the versatility and adaptability of the device. Here, a lead screw assembly 14 is used. The lead screw assembly 14 is driven by hand or motor. The end of the lead screw is connected to a worm gear structure. By driving the worm to rotate, the worm gear rotates. The moving tube 13 is provided with a threaded sleeve that is threaded with the lead screw. The worm gear and the lead screw are coaxially and fixedly connected. When the worm drives the worm gear to rotate, it drives the lead screw to rotate synchronously. The moving tube 13 is driven to rise and fall through the threaded sleeve. The worm gear has self-locking property. After the transmission stops, the power cannot be transmitted downward, thus achieving position locking.

[0050] The above description is merely an embodiment of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
