Description

Technical Field

[0001] The invention relates to the technical field of laser processing, in particular to a laser engraving machine for stainless steel engraving. Background Art

[0002] Stainless steel is widely used in architectural decoration, machinery manufacturing, aerospace and other fields due to its excellent corrosion resistance, heat resistance and mechanical strength. Therefore, in the process of engraving stainless steel, a laser engraving machine is used to operate it, and this method can be widely used in the field of fine engraving of various non-metallic materials.

[0003] In the prior art, such as the Chinese patent application publication number: CN108480848A, a laser engraving machine for stainless steel engraving is provided, including a box body, a mounting seat is fixedly connected to one side of the inner bottom wall of the box body, a motor is fixedly connected to the top of the mounting seat, the output shaft of the motor is fixedly connected to the rotating shaft through a coupling, both ends of the outer surface of the rotating shaft are fixedly sleeved with a first bevel gear, both sides of the inner bottom wall of the box body are fixedly connected with a fixing rod, the middle part of the top of the fixing rod is inlaid with a first bearing, and the inner ring of the first bearing is interference-connected with a threaded rod. The present invention uses a controller to operate the motor to rotate the rotating shaft, drive the first bevel gear to rotate, and because the first bevel gear is meshed with the second bevel gear, the threaded rod rotates to drive the fixed plate on the threaded sleeve to move up and down, and the lifting block drives the workbench to move up and down, thereby realizing the adjustment of the height of the workbench.

[0004] Although the above equipment can use the thread method to adjust the height of the workbench, thereby improving the convenience of the engraving process, the equipment still has the following problems when in use, taking the use process as an example;

[0005] During the laser engraving process, the laser beam focuses on the surface of stainless steel with its high energy density, thus forming high-intensity energy on the surface of the material, keeping the material rapidly heated up locally until it reaches the melting point or even boiling point, so that the material is locally melted and vaporized. This operation is the basis for laser engraving technology to achieve material removal or morphological changes. However, the area irradiated by the laser will produce high temperature, which will diffuse around the material to form a heat-affected zone. Although the material in the heat-affected zone has not directly reached the degree of melting or vaporization, the temperature has also increased significantly, which is easy to cause changes in the material's microstructure, such as grain The growth of heat-affected zones and the occurrence of phase changes will directly lead to changes in the mechanical and physical properties of the material, such as reduced hardness and weakened toughness. On the other hand, the heat-affected zone will also cause a significant decrease in the clarity of the engraved edge, causing the engraved edge to become blurred, seriously affecting the fineness and overall beauty of the engraved piece. What's more serious is that if the heat-affected zone is too large or the material itself is sensitive to heat, high temperature can also cause the material to deform or crack. Deformation will cause the size and shape of the engraved piece to deviate from the design requirements, while cracking will directly destroy the integrity of the engraved piece, making it unable to be used normally. Summary of the invention

[0006] The purpose of the present invention is to provide a laser engraving machine for stainless steel engraving, so as to solve the problem that in the process of laser engraving mentioned in the above background technology, the high temperature generated will diffuse to the surrounding of the material to form a heat-affected zone, causing the material to deform or crack, and the deformation will cause the size and shape of the engraved part to deviate from the design requirements.

Obviously, the implementation rules described 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 creative work are within the scope of protection of the present invention.

[0040] Embodiment 1, refer to Figure 1-Figure 12 As shown: The present invention provides a laser engraving machine for stainless steel engraving, comprising: a main body mechanism 1, an engraving mechanism 2 is fixedly installed on the adjustment end of the main body mechanism 1, and an adjustment mechanism 3 is fixedly installed on the inner surface wall of the main body mechanism 1.

[0041] The engraving mechanism 2 includes a cooling assembly 21, a set of fixed plates 23 and a movable plate 25;

[0042] The bottom of the refrigeration component 21 is fixedly connected to a group of one-way pumps 211, and the output ends of the group of one-way pumps 211 are fixedly connected to air pipes 212. The laser engraving machine body 22 is fixedly installed at the center of the bottom of the refrigeration component 21;

[0043] A set of fixed plates 23 are preset with driving grooves 231 inside, and one side of the outer wall of a set of fixed plates 23 is fixedly installed with the outer wall of the laser engraving machine body 22, the inner wall of a set of driving grooves 231 is rotatably connected with a driving rod 232, one side of the outer wall of a set of driving rods 232 is fixedly installed with a micro motor 233, the outer wall of a set of driving rods 232 is fixedly sleeved with an angle rotating plate 24, and a set of moving grooves 241 are preset inside;

[0044] A group of movable plates 25 are each provided with an inner storage tank 251 inside, and the outer walls of a group of movable plates 25 are slidably embedded in the movable groove 241 through sliders, a group of movable plates 25 are each fixedly connected to the bottom with a nozzle 252, a group of movable plates 25 are each fixedly installed with a temperature detector 253 at the bottom, a group of movable plates 25 are each fixedly connected to a one-way valve 26 on one side of the outer wall, and the input end of the one-way valve 26 is fixedly connected to the output end of the air pipe 212, a group of movable plates 25 are each fixedly connected to a compressor 27 on one side of the outer wall, a group of angle rotating plates 24 are each fixedly installed with a self-locking cylinder 28, and a group of telescopic ends of the self-locking cylinder 28 are respectively fixedly connected to the top of the movable plate 25.

[0045] In this embodiment, after the stainless steel is clamped on the top of the adjustment mechanism 3 and its position and angle are adjusted, it is necessary to perform laser engraving on the stainless steel. The laser engraving machine body 22 is started, and a laser beam is emitted from the output end of the laser engraving machine body 22. The laser beam is applied to the top of the stainless steel plate to heat it up, and a chemical or physical change occurs in the local area to achieve the purpose of engraving. During the engraving process, four groups of temperature detectors 253 arranged at the bottom will perform temperature detection on the periphery of the top of the stainless steel. The electrical signal converted by the temperature detector 253 is converted into a standard digital signal by the transmitter. At the same time, compensation wire and other technologies are used to ensure the accuracy of data transmission. The collected temperature data is sent to the processor for data processing, followed by comparison and judgment. The processor compares the current temperature with the preset temperature range to form a temperature zone. A control algorithm is used to calculate a control signal according to the temperature zone, and then the working state of the actuators such as the automatic micro motor 233, the nozzle 252, the compressor 27 and the one-way pump 211 is controlled according to the control signal to achieve precise temperature control.

[0046] During the automatic control process, first, the refrigeration component 21 is running. The refrigeration component 21 is formed by a refrigeration device and a bottom storage space. First, the refrigerant is compressed into a high-temperature and high-pressure gas. The temperature and pressure of the refrigerant will increase. When the high-temperature and high-pressure refrigerant gas passes through the condenser, it exchanges heat with the outside air and releases heat into the environment, thereby cooling and turning into a high-pressure liquid. The condenser is usually located on the back or side of the refrigerator, and dissipates heat into the air through heat sinks and heat pipes. When the high-pressure liquid refrigerant passes through the expansion valve, the pressure suddenly drops, causing the refrigerant to evaporate rapidly into a low-temperature and low-pressure liquid and gas mixture. In this process, the temperature of the refrigerant will also drop. After the low-temperature and low-pressure refrigerant enters the evaporator, it absorbs the heat inside the storage space and evaporates into a gas. Then, The temperature of the storage space is lowered, and under the transmission of the multiple groups of one-way pumps 211 at the bottom, the low-temperature gas can be transferred to the inside of the inner storage tank 251 through the air pipe 212 as a medium. Then the compressor 27 will pressurize the inside of the inner storage tank 251, and in this process, a cooler is installed at the outlet of the compressor 27 to neutralize the temperature increase caused by the compression process. After the treatment, a high-pressure state is formed inside the inner storage tank 251. At this time, the controller starts the nozzle 252 at the bottom, and the compressed gas is accelerated and forms a gas line to be sprayed out through the nozzle 252, keeping the low-temperature gas covering the high-temperature area, forming the neutralization of the high temperature after engraving, and four groups of such devices are set, which can maintain the process of laser engraving and complete the temperature neutralization process from different aspects;

[0047] In this process, the nozzle 252 and the movable plate 25 are connected by an angle adjuster to control the nozzle 252, and the output end of the self-locking cylinder 28 can push the movable plate 25 downward when it is extended and retracted, keeping the bottom nozzle 252 close to the laser engraving area.

[0048] Embodiment 2, according to Figure 1 , Figure 2 , Figure 8 , Fig. 9 , Fig.10 as well as Fig.11 As shown, the adjustment mechanism 3 includes a crossbeam plate 31, a second linkage rod 331 and a disc 37;

[0049] The outer wall of the crossbeam plate 31 is fixedly connected with a support plate 311, and two triangular rectangular plates 32 are fixedly installed on the top of the support plate 311. A first linkage rod 321 is fixedly inserted into the interior of one of the two triangular rectangular plates 32 through a bearing, and a first gear 322 is fixedly sleeved on the outer wall of the first linkage rod 321. A threaded transmission rod 323 is transmission-connected to the outer wall of the first gear 322, and a linear motor 324 is fixedly connected to one side of the outer wall of the threaded transmission rod 323. A side plate 325 is fixedly sleeved with a bearing near the edge of the outer wall of the threaded transmission rod 323, and one side of the outer wall of the side plate 325 is fixedly connected to one side of the outer wall of one of the two triangular rectangular plates 32.

[0050] A second linkage rod 331 is fixedly inserted into the interior of the other of the two triangular rectangular plates 32 through a bearing, a placement plate 36 is fixedly sleeved between the outer walls of the first linkage rod 321 and the second linkage rod 331, a linkage plate 332 is fixedly installed on one side of the outer wall of the first linkage rod 321, a main rod 333 is fixedly inserted into the interior of the linkage plate 332 through a bearing, a driven gear 334 is fixedly sleeved on the outer wall of the main rod 333, a chain 335 is meshed and transmitted on the outer wall of the driven gear 334, and the inner wall of the chain 335 is fixedly sleeved with the outer wall of the driven gear 334. The driving gear 336 is meshed with the main rod 333, and a short rod 337 is fixedly inserted inside the driving gear 336, and the outer wall of the short rod 337 is fixedly inserted inside the linkage plate 332 through a bearing, and a stepper motor 338 is fixedly connected to one side of the outer wall of the driving gear 336, and one side of the outer wall of the stepper motor 338 is fixedly connected to one side of the outer wall of the linkage plate 332, and the outer wall of the main rod 333 is movably supported by two receiving plates 339 through a bearing, and the tops of the two receiving plates 339 are fixedly connected to the bottom of the placement plate 36;

[0051] A first bevel gear 34 is fixedly connected to one side of the outer wall of the main rod 333, and a second bevel gear 35 is meshed and transmitted on the outer wall of the first bevel gear 34. A straight rod 351 is fixedly connected to the top of the second bevel gear 35, and the outer wall of the straight rod 351 is fixedly supported on the inside of the placement plate 36 through a bearing, and a disc 37 is fixedly installed on the top of the straight rod 351. A plurality of groups of embedded grooves 371 are preset inside the disc 37, and the inner walls of the plurality of groups of embedded grooves 371 are all slidably embedded with embedded seats 372, and the tops of the plurality of groups of embedded seats 372 are fixedly connected with extension plates 373, and one side of the outer wall of the plurality of groups of extension plates 373 is fixedly connected with a clamping plate 374, and a plurality of double-axis cylinders 38 are fixedly connected to the outer wall of the disc 37, and the telescopic ends of the plurality of double-axis cylinders 38 are respectively fixedly connected to one side of the outer wall of the extension plate 373.

[0052] In this embodiment, when the equipment is in use, the stainless steel material to be processed is placed on the top of the disc 37. When the multiple double-axis cylinders 38 are powered on, their output ends are retractable, pushing the front extension plate 373 to move forward. Because the extension plate 373 is in a fixed connection state with the embedded seat 372 at the bottom, and the embedded seat 372 is slidably limited in the embedded groove 371, through this adjustment method, the clamping plates 374 fixed on one side of the outer wall of the multiple extension plates 373 converge inward. After the multiple clamping plates 374 come into contact with the stainless steel material, an extrusion sensor is set at the contact end of the clamping plate 374. When the pressure value reaches a certain value, the external control system stops the multiple double-axis cylinders 38, thereby maintaining the stabilizing effect on the stainless steel.

[0053] When stainless steel needs to be laser engraved and the stainless steel needs to be kept in position, direction and angle, the linear motor 324 is powered on first, and its output end starts to rotate. Under the support of the side plate 325, the threaded transmission rod 323 rotates on its own. During the rotation of the threaded transmission rod 323, it can achieve meshing transmission with the first gear 322. Because the first gear 322 and the first linkage rod 321 are fixed to each other, and the first linkage rod 321, the placement plate 36 and the second linkage rod 331 are also fixedly installed, when the first gear 322 rotates, the placement plate 36 can be kept adjusted to provide the angle adjustment requirement for laser engraving.

[0054] In the other direction, when the stepper motor 338 is energized and its output end starts to rotate, the short rod 337 is in a fixed state with the driving gear 336, thereby driving the short rod 337 to rotate inside the linkage plate 332. Because the driving gear 336, the chain 335 and the driven gear 334 are in a meshing transmission state, the main rod 333 fixed on one side of the outer wall of the driven gear 334 is rotatably connected to the inside of the linkage plate 332. Under the transmission between each other, the rotation of the main rod 333 drives the first bevel gear 34 fixed on the other side to rotate. The first bevel gear 34 and the second bevel gear 35 are in meshing transmission, thereby keeping the straight rod 351 rotating. The disk 37 is fixed on the top of the straight rod 351. This adjustment can keep the disk 37 rotating and adjust the direction of the stainless steel clamped on the top of the disk 37.

When the first movable frame 12 is limited by the outer walls of the two first limit rods 112, the first movable frame 12 and the components fixed thereto move horizontally. When the second external motor 123 is powered on, its output end drives the second threaded rod 121 to rotate, so that the second threaded rod 121 and the inside of the second movable frame 13 are threadedly transmitted. The movable frame 13 slides in cooperation with the two second limit rods 122, and the second movable frame 13 and the components fixed thereto are adjusted to move horizontally. Finally, when the servo motor 14 is powered on, its output end drives the third threaded rod 141 to rotate, and the third threaded rod 141 and the inner part of the adjusting frame 15 generate threaded transmission. When the adjusting frame 15 slides and is limited in cooperation with the outer walls of the two third limit rods 142, the adjusting frame 15 and the engraving mechanism 2 fixed thereto are adjusted up and down, so as to adjust the position and depth of the engraving mechanism 2 during the engraving process.

[0058] The working principle of the whole mechanism is as follows: when using the device, the stainless steel material to be processed must first be placed on the top of the disc 37. Subsequently, when the multiple double-axis cylinders 38 are powered on, their output ends telescope to push the front extension plate 373 forward. Since the extension plate 373 is fixedly connected to the embedded seat 372 at the bottom, and the embedded seat 372 is slidably limited in the embedded groove 371, this adjustment method will cause the clamping plates 374 fixed on one side of the outer wall of the multiple extension plates 373 to converge inward. When the clamping plates 374 come into contact with the stainless steel material and trigger the extrusion sensor to reach a preset pressure value, the external control system will stop the operation of the double-axis cylinders 38 and lock itself, thereby firmly clamping the stainless steel. If the stainless steel material needs to be laser engraved and its position, direction or angle needs to be adjusted, the linear motor 324 can be powered on first to make its output end start to rotate. With the cooperation of the side plate 325, the threaded transmission rod 323 starts to rotate and meshes with the first gear 322. Since the first gear 322 is fixedly connected to the first linkage rod 321, and the first linkage rod 321, the placement plate 36 and the second linkage rod 331 are also fixedly installed, the rotation of the first gear 322 will drive the placement plate 36 to rotate and adjust to meet the angle adjustment requirements of laser engraving. On the other hand, after the stepper motor 338 is powered on, its output end starts to rotate, driving the short rod 337 fixed to the driving gear 336 The linkage plate 332 rotates inside, and a meshing transmission is formed between the driving gear 336, the chain 335 and the driven gear 334, and the main rod 333 fixed on one side of the outer wall of the driven gear 334 also rotates inside the linkage plate 332. This transmission method allows the main rod 333 to rotate and drive the first bevel gear 34 fixed on the other side to rotate, and then mesh with the second bevel gear 35 to cause the straight rod 351 to rotate. Since the disk 37 is fixed on the top of the straight rod 351, this adjustment method can realize the rotation of the disk 37, and then adjust the direction of the stainless steel material clamped on the top of the disk 37. When the stainless steel material is clamped on the top of the adjustment mechanism 3, its position, direction and angle are adjusted. The laser engraving machine body 22 is started to engrave. The output end of the laser engraving machine body 22 emits a laser beam, which acts on the top of the stainless steel material, causing it to heat up and undergo chemical or physical changes to achieve the purpose of engraving. During the engraving process, the four sets of temperature detectors 253 arranged at the bottom will monitor the temperature around the top of the stainless steel material. During the laser engraving process, the first external motor 113, the second external motor 123 and the servo motor 14 are powered on and rotated, respectively through the cooperation of the threaded transmission and the limit rod, to achieve the lateral and longitudinal movement of the first moving frame 12, the second moving frame 13 and the adjustment frame 15, thereby adjusting the position, direction and depth of the engraving mechanism 2 during the engraving process;

[0059] The temperature detector 253 converts the detected engraving area temperature into an electrical signal, which is converted into a standard digital signal by a transmitter, and the accuracy of data transmission is ensured by technologies such as compensation wires. The collected temperature data is sent to the processor for data processing and comparison and judgment. The processor compares the current temperature with the preset temperature range to form a temperature zone, and calculates a control signal according to the control algorithm. Then, the working state of the actuators such as the automatic micro motor 233, the nozzle 252, the compressor 27 and the one-way pump 211 is automatically adjusted according to the control signal to achieve precise temperature control;

[0060] In the automatic control process, the refrigeration component 21 is operated first, and the refrigerant is compressed into a high-temperature and high-pressure gas under compression, and heat is exchanged with the outside air through the condenser, releasing heat and cooling into a high-pressure liquid. The pressure of the high-pressure liquid refrigerant decreases when passing through the expansion valve, and it quickly evaporates into a low-temperature and low-pressure liquid and gas mixture, and absorbs the heat inside the storage space. Subsequently, the low-temperature and low-pressure refrigerant enters the evaporator to continue evaporating, reducing the temperature of the storage space. Under the transmission of multiple groups of one-way pumps 211 at the bottom, the low-temperature gas is transmitted to the inside of the inner storage tank 251 through the air pipe 212. The compressor 27 pressurizes the inside of the inner storage tank 251, and a cooler is installed at the outlet to neutralize the temperature increase caused by the compression process. After processing, a high-pressure state is formed inside the inner storage tank 251. At this time, the controller starts the nozzle 252 at the bottom to accelerate the compressed gas and form a gas line to spray out, covering the high-temperature area to neutralize the high temperature after engraving. The device is set with four groups, which can complete the temperature neutralization process of the engraving area from different aspects and improve the comprehensiveness of the processing.
