[0001] The present invention relates to the technical field of engraving machines, and in particular to a high-precision engraving machine control device and system. Background Art

[0002] Engraving, in principle, is a combination of drilling and milling, and engraving machines offer a variety of data input modes to meet specific needs. Mechanical engraving machines are the most commonly used and widely applicable type of CNC engraving machine, primarily used for cutting, relief engraving, and embossing metals, jewelry, molds, parts, architectural models, small signs, and three-dimensional crafts. When processing certain molds, it's often necessary to use an engraving machine to carve a specific pattern onto the mold.

[0003] In traditional high-precision engraving operations, when dealing with the debris generated by engraving, the currently commonly used dust removal method mostly uses a single external dust collection device, which directly sucks away the generated dust through a connecting pipe and discharges it into the atmosphere.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] As described in the background technology, in traditional high-precision engraving operations, when dealing with the debris generated by the engraving, the currently commonly used dust removal method mostly uses a single external dust suction device, which directly sucks away the generated dust through a connecting pipe and discharges it into the atmosphere.

[0044] Through the above content, the negative pressure pump 201 generates a negative pressure suction effect through the dust suction pipe 202, and the dust suction hole with a conical structure can efficiently suck the debris generated by engraving into it, effectively preventing the debris from interfering with the normal operation of the engraving head 401. The inhaled debris enters the filter box 203 through the dust suction pipe 202, and will be effectively blocked when passing through the filter 2031. The filtered gas is transported to the air cylinder 303 through the recovery air pipe 204 and ejected. This unique dust removal method of blowing and sucking not only realizes the recycling and reuse of the dust suction gas.

[0046] Through the above content, the driving motor 4 drives the engraving head 401 to rotate, and through the engagement between the worm 402 and the worm wheel 404, the transmission rod 403 drives the two reciprocating screws 405 to rotate, so that the pin plate 406 located in the reciprocating groove of the two reciprocating screws 405 moves back and forth. At the same time, the limiting hole can limit the pin plate 406 to ensure its horizontal movement effect.

[0047] Reference Figure 1 、 Figure 2 and Figure 8 Preferably, the heat recovery control mechanism includes a control box 501 installed on the top of the bracket 5, a controller installed in the control box 501, and a heat dissipation fan 502 fixed on the control box 501.

[0048] Through the above content, the heat dissipation fan 502 can transport the heat generated by the operation of the controller to the preheating box 505 through the heat recovery pipe 504, thereby accelerating the preheating of the heating wire.

[0049] Reference Figure 4 , preferably, a lifting assembly for driving the lifting plate 3 to perform lifting operations; the lifting assembly includes a support plate 7 correspondingly arranged on the side of the lifting plate 3 close to the bracket 5, a lifting screw rod 701 rotatably arranged on the support plate 7, and two second auxiliary rods 702 fixed on the support plate 7 and symmetrically arranged with the lifting screw rod 701 as the center, a second screw sleeve 703 connected to the lifting plate 3 is screwed on the lifting screw rod 701, and a second auxiliary rod 702 is slidably provided with a second sliding sleeve connected to the lifting plate 3, and a lifting motor 704 connected to the lifting screw rod 701 is installed on the support plate 7;

[0050] Through the above content, due to the threaded relationship between the lifting screw rod 701 and the second screw sleeve 703, and the effective limiting effect of the second auxiliary rod 702 and the second sliding sleeve, the lifting screw rod 701 can drive the second screw sleeve 703 to move downward steadily in the vertical direction until the engraving head 401 comes into contact with the surface of the engraving workpiece, thereby achieving the effect of lifting and lowering the engraving head 401.

[0051] Reference Figure 4Preferably, a displacement assembly for driving the movement of the lifting assembly comprises a moving screw rod 601 rotatably arranged along the longitudinal direction of the bracket 5, a first screw sleeve screwed on the moving screw rod 601 and connected to the support plate 7, two first auxiliary rods 602 corresponding to both sides of the moving screw rod 601 and fixed on the bracket 5, a first sliding sleeve connected to the support plate 7 is provided on the first auxiliary rod 602, a moving motor 603 connected to the moving screw rod 601 and a base 6 installed on the bracket 5 to support the moving motor 603 are provided.

[0052] Through the above content, the sliding limit mechanism between the first sleeve and the first auxiliary rod 602 is utilized to enable the movable screw 601 to push the lifting plate 3 to maintain horizontal and stable movement through the screwed first sleeve, thereby achieving comprehensive and detailed engraving processing of the engraving piece.

[0053] Reference Figure 4 Preferably, a pushing assembly installed on the workbench 1 for pushing the carrier 2 located at the lower part of the lifting assembly, the pushing assembly includes a pushing screw rod 8 rotatable along the length direction, a third screw sleeve 801 screwed on the pushing screw rod 8 and connected to the carrier 2, a third auxiliary rod 802 correspondingly arranged on both sides of the pushing screw rod 8 and a third sliding sleeve slidably sleeved on the third auxiliary rod 802 and connected to the carrier 2, and a pushing motor 803 connected to the pushing screw rod 8 is installed on the workbench 1 corresponding to the lower part of the bracket 5.

[0054] Through the above content, when the push screw 8 starts to rotate, with the help of the ingenious sliding limit design between the third sliding sleeve connected to the carrier 2 and the third auxiliary rod 802, and relying on the tight screw relationship between the third screw sleeve 801 and the push screw 8, it is ensured that the carrier 2 can maintain a horizontal state, move smoothly and accurately to the position directly below the engraving head 401 and then stop.

[0055] Reference Figure 1 and Figure 6 Preferably, a retractable fixed plate 902 for clamping the engraved piece is relatively provided on the carrier 2, and a plurality of support blocks 9 and an electric push rod 901 installed on the support blocks 9 and connected to the fixed plate 902 are symmetrically provided on the carrier 2.

[0056] Through the above content, the electric push rod 901 is used to drive the fixing plates 902 to move closer to or away from each other, so as to achieve the effect of clamping and fixing the workpiece to be engraved.

[0057] Reference Figure 9 and Figure 10Preferably, a system of a high-precision engraving machine control device as described above includes a control module 5010 connected to the controller, the control module 5010 is connected to a monitoring module 5012 for real-time photography of the engraving operation, a display module 5013 for displaying the image captured by the monitoring module 5012, a burr analysis module 5014 for identifying the image on the display module 5013, a power supply module 5011 for powering the controller, and an environment recording module 5015 for monitoring the engraving operation environment, the environment recording module 5015 is connected to a laser particle counting module 50150, the laser particle counting module 50150 includes a laser particle counter 50151 for detecting and quantifying suspended particulate matter in the air based on the principle of laser scattering.

[0058] Through the above content, the power module 5011 can provide power to the controller in real time, the monitoring module 5012 can shoot the engraving process in real time and display it through the display module 5013, and the burr analysis module 5014 in the controller can identify, analyze and record the captured images. When burrs on the engraved part are identified, the burr area can be engraved and trimmed again. The laser particle counter 50151 can use the laser scattering principle to detect and analyze the concentration, size distribution and number of suspended particulate matter in the air. When the laser beam irradiates the particles in the air, the particles will scatter the light, and the intensity of the scattered light is proportional to the particle diameter. After receiving these scattered signals, the laser particle counting sensor converts them into electrical pulses through the photoelectric converter, and finally the controller processes them to obtain the number and size distribution data of the particles, so as to facilitate the subsequent better processing of debris in the working environment and accurately control the cleanliness standard of the working environment.

[0059] The implementation principle of the high-precision engraving machine control device and system of the present application embodiment is as follows: when engraving is required, the engraving workpiece to be processed is first properly placed on the carrier 2. At this time, the controller takes effect, driving the electric push rod 901 to operate, which in turn drives the fixing plate 902 to slowly approach the engraving workpiece and accurately clamp it, thereby achieving a stable fixing effect.

[0060] Before the engraving operation officially begins, the controller performs a series of actions. First, it activates the negative pressure pump 201, then the propulsion motor 803, causing the propulsion screw 8 to begin rotating. Thanks to the ingenious sliding stop design between the third sleeve connected to the carrier 2 and the third auxiliary rod 802, and the tight threaded connection between the third sleeve 801 and the propulsion screw 8, the carrier 2 remains horizontal, moving smoothly and precisely to a position directly below the engraving head 401 before stopping.

[0061] Next, the controller activates the lifting motor 704. Driven by the lifting motor 704, its output shaft drives the lifting screw 701 to rotate in an orderly manner. Due to the threaded connection between the lifting screw 701 and the second screw sleeve 703, and the effective limiting effect of the second auxiliary rod 702 and the second sliding sleeve, the lifting screw 701 can drive the second screw sleeve 703 to move steadily downward in the vertical direction until the engraving head 401 contacts the surface of the engraving workpiece.

[0062] After completing the above preparations, the controller issues another command to start the drive motor 4. The output shaft of the drive motor 4 drives the movable screw 601 to rotate. The sliding limit mechanism between the first sleeve and the first auxiliary rod 602 is used to enable the movable screw 601 to push the lifting plate 3 to maintain horizontal and stable movement through the screwed first sleeve, thereby achieving comprehensive and detailed engraving of the engraved object. During the engraving process, the power module 5011 can provide real-time power to the controller, the monitoring module 5012 can capture the engraving process in real time and display it on the display module 5013. At the same time, the burr analysis module 5014 in the controller can identify, analyze and record the captured images. When burrs are identified on the engraved object, the burr area can be engraved and trimmed again. The laser particle counter 50151 can use the principle of laser scattering to detect and analyze the concentration, size distribution and number of suspended particulate matter in the air. When the laser beam irradiates particles in the air, the particles scatter the light, and the intensity of the scattered light is proportional to the particle diameter. After receiving these scattered signals, the laser particle counting sensor converts them into electrical pulses through a photoelectric converter, which is finally processed by the controller to obtain the number and size distribution data of the particles, so as to better handle the debris in the working environment and accurately control the cleanliness standards of the working environment.

[0063] During the entire engraving process, debris is inevitably generated. For this reason, the system is specially equipped with a negative pressure dust removal device. The negative pressure pump 201 generates a negative pressure suction effect through the dust suction pipe 202, and the dust suction hole with a conical structure can efficiently suck the debris generated by the engraving into it, effectively preventing the debris from interfering with the normal operation of the engraving head 401. The inhaled debris enters the filter box 203 through the dust suction pipe 202 and is effectively blocked when passing through the filter 2031. The filtered gas is transported to the air cylinder 303 through the recovery air pipe 204 and ejected. This unique dust removal method of blowing and sucking not only realizes the recycling and reuse of the dust suction gas, but also significantly improves the dust removal efficiency.

[0064] It is worth mentioning that when the engraving head 401 rotates, the precise meshing transmission between the worm 402 and the worm wheel 404 achieves a deceleration effect, and drives the transmission rod 403 to rotate synchronously. The transmission rod 403 further drives the two reciprocating screws 405 to rotate, so that the two pin plates 406 connected thereto can move back and forth regularly along the reciprocating grooves on the reciprocating screws 405. The limiting holes play a precise limiting role in the movement of the pin plates 406, ensuring the stability of their horizontal movement. The pin plate 406 drives the two air cylinders 303 to move closer to or away from each other through the moving plate 302, thereby more efficiently "stirring" the dust and guiding it to the negative pressure area formed by the dust suction hole, greatly reducing the sedimentation and adhesion of debris on the surface of the engraving.

[0065] In addition, considering that the controller will generate heat during long-term operation, the system is also equipped with an intelligent heat dissipation and heat recovery device. When the controller generates heat, the heat dissipation fan 502 intervenes in time and transfers the heat to the preheating box 505 through the heat recovery pipe 504. At the same time, the heating wire in the preheating box 505 starts heating synchronously, and the temperature sensor monitors the temperature changes in the preheating box 505 in real time. The heat entering the preheating box 505 can be quickly and effectively utilized. The hot air generated in the preheating box 505 can be transported to the blowpipe 303 through the heat supply pipe 506 and blown evenly toward the engraving area by the blowpipe 303. This design can achieve controlled heating of the engraving area locally or as a whole, significantly reducing the viscous resistance of the material (such as plastic deformation in the molten state, relaxation of molecular chains, etc.), allowing the engraving head 401 to cut into the material surface more easily, effectively reducing problems such as excessive cutting force and increased tool wear caused by viscosity, and further improving the efficiency and quality of the engraving operation.
