A multi-station laser engraver and method of use

Abstract

This invention belongs to the field of laser engraving machine technology, and in particular to a multi-station laser engraving machine and its usage method. It includes a support platform and a conveying device. An engraving mechanism and an automatic feeding mechanism are fixedly mounted on the outer side of the support platform. A rotary motor on the rotary feeding mechanism drives the turntable to rotate 120 degrees each time, allowing for the rotary conveying of the workpiece to be engraved after transfer. When the workpiece is rotated and conveyed to the area below the engraving mechanism, multiple sets of laser engraving devices on the engraving mechanism can perform multi-station rapid engraving on the workpiece within the limiting groove. After engraving is completed, the rotary motor continues to drive the turntable to rotate 120 degrees. When the engraved workpiece rotates to the linkage protrusion, the linkage protrusion can lift the linkage demolding mechanism upwards, automatically completing the demolding. The entire process is continuous and highly automated, effectively solving the problems of low efficiency of manual feeding, inaccurate positioning leading to engraving deviations, and easy damage to the workpiece during transfer.

Description

Technical Field

[0001] This invention belongs to the field of laser engraving machine technology, specifically relating to a multi-station laser engraving machine and its usage method. Background Technology

[0002] In fields such as metal material processing, mold manufacturing, and complex parts forming, traditional single heat source processing methods often cannot simultaneously meet the comprehensive requirements of high efficiency, high quality, and complex geometric shape processing. Currently, laser processing and electric arc processing are two mainstream material processing technologies, each with certain limitations. Automatic and semi-automatic electric arc processing achieves high-efficiency, high-precision, and high-flexibility composite processing by combining the functions of electric arc processing and laser engraving, the collaborative layout of multiple workstations, and the integration of an automated control system.

[0003] Laser engraving technology, due to its advantages of high precision and non-contact processing, is widely used in fields such as sign making, craft decoration, and electronic components. Traditional laser engraving equipment generally adopts a single-station operation mode, requiring manual completion of processes such as loading, positioning, and unloading. This results in problems such as low efficiency, high labor intensity, and poor positioning consistency. Especially in mass production scenarios, frequent manual intervention not only prolongs the production cycle but also easily leads to engraving position deviation or workpiece damage due to operational errors, affecting the finished product qualification rate. Although existing automation improvement solutions have partially achieved mechanical loading, there are still significant bottlenecks. Moreover, the demolding process mostly relies on independent pneumatic or electric mechanisms, which are complex in structure and have poor synchronization, making it impossible to achieve efficient and seamless connection of the entire process from workpiece storage, positioning, engraving to demolding.

[0004] To address the aforementioned issues, this application proposes a multi-station laser engraving machine and its usage method. Summary of the Invention

[0005] This invention provides a multi-station laser engraving machine and its usage method, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-station laser engraving machine, comprising a support platform and a conveying device, wherein an engraving mechanism and an automatic feeding mechanism are fixedly arranged on the outer side of the support platform, an automatic feeding device is fixedly arranged on one side of the automatic feeding mechanism, an intelligent control terminal and a press-type sensing module are fixedly arranged on the automatic feeding device, a rotary feeding mechanism is fixedly arranged in the middle of the support platform, a linkage demolding mechanism is inserted through the rotary feeding mechanism, and a linkage protrusion is fixedly arranged on the top of the support platform; The automatic feeding mechanism includes a vertical plate, a drive motor is fixedly mounted on one side of the vertical plate, a first sprocket is fixedly mounted on the end of the output shaft of the drive motor, a second sprocket is rotatably mounted on one side of the vertical plate, a chain is provided between the second sprocket and the first sprocket, a first swing arm is rotatably mounted on one end of the second sprocket and one end of the first sprocket, a second swing arm is connected to one end of the first swing arm through a hinge, and an engraving adsorption mechanism is fixedly mounted on the bottom end of the second swing arm.

[0007] Preferably, the engraving adsorption mechanism includes a connecting plate fixedly disposed at the bottom end of the second swing arm, a pin inserted through the connecting plate, a mounting plate fixedly disposed at the bottom end of the pin, a buffer spring disposed between the mounting plate and the connecting plate, and negative pressure suction cups fixedly disposed at equal intervals at the bottom of the mounting plate.

[0008] Preferably, the engraving mechanism includes a frame fixedly installed on the outside of the support platform, a telescopic component fixedly installed at the top of the frame, a rectangular plate fixedly installed at the bottom of the telescopic component, and laser engraving devices fixedly installed at equal intervals at the bottom of the rectangular plate.

[0009] Preferably, the automatic feeding device includes an outer casing, and the outer casing has equidistant carving storage slots. The carving storage slots are equipped with a lifting component with sensing function and a carving component to be carved, and the lifting component with sensing function is located below the carving component.

[0010] Preferably, the press-type sensing module, the intelligent control terminal, and the lifting component with sensing function are electrically connected.

[0011] Preferably, the rotary feeding mechanism includes a rotary motor fixedly mounted at the bottom of the support platform, the rotary motor being fixedly connected to a turntable via a shaft, and the turntable having a limit groove.

[0012] Preferably, an expansion-type annular component is fixedly provided in the inner cavity of the limiting groove.

[0013] Preferably, the linkage demolding mechanism includes a lifting slide rod, a return spring is sleeved on the outside of the lifting slide rod, a top plate and a linkage plate are respectively provided at the upper and lower ends of the lifting slide rod, and a universal roller is provided at the bottom end of the linkage plate.

[0014] Preferably, the linkage protrusion is configured as a trapezoidal structure, and the linkage protrusion is located on the top of the support platform near the conveying device.

[0015] A method for using a multi-station laser engraving machine includes the following steps: S1. When using, first place the workpiece to be engraved neatly into the engraving storage slot on the automatic feeding device, and then turn on the drive motor on the automatic feeding mechanism. When the drive motor rotates in the forward and reverse directions, the first sprocket and the chain can drive the second sprocket to rotate synchronously in the forward and reverse directions. At this time, the first sprocket and the second sprocket can drive the engraving adsorption mechanism to swing back and forth left and right through the first swing arm and the second swing arm. The engraving adsorption mechanism swings back and forth left and right to quickly transfer the workpiece to be engraved stored in the automatic feeding device into the limit slot on the rotary feeding mechanism to automatically complete the feeding. S2. After automatic feeding is completed, the rotary feeding mechanism is opened. The rotary motor on the rotary feeding mechanism drives the turntable to rotate 120 degrees each time, which can rotate and transport the workpiece to be engraved after transfer. When the workpiece is rotated and transported to the bottom of the engraving mechanism, the multiple sets of laser engraving devices on the engraving mechanism can perform multi-station rapid engraving on the workpiece in the limiting groove. After engraving is completed, the rotary motor continues to drive the turntable to rotate 120 degrees. When the engraved workpiece rotates to the linkage protrusion, the linkage protrusion can push the linkage demolding mechanism upward. After being pushed upward, the linkage demolding mechanism can push the engraved workpiece out of the limiting groove to complete the demolding. Then, the workpiece is taken away and placed on the conveying device for transport to the next processing program. S3. The number of times the automatic feeding mechanism transfers the workpiece to be engraved can be counted through the press-type sensing module. Each time the workpiece to be engraved is transferred, the press-type sensing module is triggered once and the sensing signal is sent to the intelligent control terminal. The intelligent control terminal can automatically control the lifting component with sensing function to lift upward once, so that the workpiece to be engraved stored in the engraving workpiece storage tank is always at a certain height, so that the workpiece to be engraved can be adsorbed by the engraving workpiece adsorption mechanism at the bottom of the automatic feeding mechanism. When the workpiece to be engraved stored in the engraving workpiece storage tank has been transferred, the pressure sensor at the top of the lifting component with sensing function can no longer detect pressure. At this time, the intelligent control terminal will control the alarm system to sound an alarm to remind the staff to add workpieces to be engraved.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting up an automatic feeding mechanism, when the drive motor on the automatic feeding mechanism rotates in both directions, the first sprocket and the chain can drive the second sprocket to rotate synchronously in both directions. At this time, the first sprocket and the second sprocket can drive the engraving workpiece adsorption mechanism to swing back and forth left and right through the first swing arm and the second swing arm. The engraving workpiece adsorption mechanism, which swings back and forth left and right, can quickly transfer the workpiece to be engraved stored in the automatic feeding device to the limiting groove on the rotary feeding mechanism to automatically complete the feeding, saving time and effort. The limiting groove can accurately position the transferred workpiece to be engraved, which can avoid the workpiece to be engraved shaking during laser engraving and affect the engraving accuracy. By setting a buffer spring on the engraving workpiece adsorption mechanism, the buffering performance of the engraving workpiece adsorption mechanism can be effectively improved, which can avoid the damage caused by violent impact between the negative pressure suction cup and the workpiece to be engraved when transferring the workpiece.

[0017] 2. By setting up a press-type sensor module, the number of times the automatic feeding mechanism transfers the workpiece to be engraved can be counted. Each time the workpiece to be engraved is transferred, the press-type sensor module is triggered once and sends a sensing signal to the intelligent control terminal. The intelligent control terminal can automatically control the lifting component with sensing function to lift upward once, so that the workpiece to be engraved stored in the engraving workpiece storage tank is always at a certain height, so that the workpiece to be engraved can be adsorbed by the engraving workpiece adsorption mechanism at the bottom of the automatic feeding mechanism. When the workpiece to be engraved stored in the engraving workpiece storage tank has been transferred, the pressure sensor at the top of the lifting component with sensing function can no longer detect pressure. At this time, the intelligent control terminal will control the alarm system to sound an alarm to remind the staff to add workpieces to be engraved.

[0018] 3. By setting up a rotary feeding mechanism, the rotary motor on the rotary feeding mechanism drives the turntable to rotate 120 degrees each time, which can rotate and transport the workpiece to be engraved after transfer. When the workpiece is rotated and transported to the bottom of the engraving mechanism, the multiple sets of laser engraving devices set on the engraving mechanism can perform multi-station rapid engraving on the workpiece in the limiting groove. After engraving is completed, the rotary motor continues to drive the turntable to rotate 120 degrees. When the engraved workpiece rotates to the linkage protrusion, the linkage protrusion can lift the linkage demolding mechanism upward. After being lifted upward, the linkage demolding mechanism can push the engraved workpiece out of the limiting groove to complete the demolding. The whole process is continuous and highly automated, which can effectively solve the problems of low efficiency of manual feeding, engraving deviation caused by inaccurate positioning, and easy damage to the workpiece during the transfer process.

[0021] 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.

[0022] Examples, such as Figure 1-10 As shown, a multi-station laser engraving machine includes a support platform 1 and a conveying device 2. An engraving mechanism 3 and an automatic feeding mechanism 4 are fixedly mounted on the outside of the support platform 1. An automatic feeding device 5 is fixedly mounted on one side of the automatic feeding mechanism 4. An intelligent control terminal 6 and a press-type sensing module 7 are fixedly mounted on the automatic feeding device 5. The press-type sensing module 7 can count the number of times the automatic feeding mechanism 4 transfers the workpiece 504 to be engraved. Each transfer of the workpiece 504 triggers the press-type sensing module 7, sending a sensing signal to the intelligent control terminal 6. The intelligent control terminal 6 can automatically control the lifting component 503 with sensing function to lift upwards once, ensuring that the workpiece 504 stored in the engraving workpiece storage tank 502 is always at a certain height, facilitating the adsorption mechanism 408 at the bottom of the automatic feeding mechanism 4 to adsorb the workpiece 504. When all the workpieces 504 stored in the engraving workpiece storage tank 502 have been transferred, the pressure sensor at the top of the lifting component 503 with sensing function can no longer detect pressure. At this time, the intelligent control terminal 6 will control the alarm system to issue an alarm reminder. The operator adds the workpiece 504 to be engraved. A rotary feeding mechanism 8 is fixedly installed in the middle of the support platform 1. A linkage demolding mechanism 9 is inserted into the rotary feeding mechanism 8. A linkage protrusion 10 is fixedly installed on the top of the support platform 1. The rotary motor 801 on the rotary feeding mechanism 8 drives the turntable 802 to rotate 120 degrees each time, which can rotate and transport the workpiece 504 after it has been transferred. When the workpiece 504 is rotated and transported to the bottom of the engraving mechanism 3, the multiple sets of laser engraving devices 304 set on the engraving mechanism 3 engrave the workpiece 504 in the limiting groove 803. Multi-station rapid engraving is performed. After engraving is completed, the rotary motor 801 drives the turntable 802 to rotate 120 degrees. When the engraved workpiece 504 rotates to the linkage protrusion 10, the linkage protrusion 10 can push the linkage demolding mechanism 9 upward. After being pushed upward, the linkage demolding mechanism 9 can push the engraved workpiece 504 out of the limiting groove 803 to complete the demolding. Then, the workpiece 504 is taken away and placed on the conveying device 2 for conveying to the next processing program. The automatic feeding mechanism 4 includes a vertical plate 401. A drive motor 402 is fixedly mounted on one side of the vertical plate 401. A first sprocket 403 is fixedly mounted on the end of the output shaft of the drive motor 402. A second sprocket 404 is rotatably mounted on one side of the vertical plate 401. A chain 405 is provided between the second sprocket 404 and the first sprocket 403. A first swing arm 406 is rotatably mounted on one end of the second sprocket 404 and one end of the first sprocket 403. A second swing arm 407 is connected to one end of the first swing arm 406 via a hinge. A carving part suction device is fixedly mounted at the bottom end of the second swing arm 407. When the drive motor 402 rotates in both directions, the first sprocket 403 and the chain 405 can drive the second sprocket 404 to rotate synchronously in both directions. At this time, the first sprocket 403 and the second sprocket 404 can drive the engraving adsorption mechanism 408 to swing back and forth left and right through the first swing arm 406 and the second swing arm 407. The engraving adsorption mechanism 408 swings back and forth left and right to quickly transfer the engraved part 504 stored in the automatic feeding device 5 to the limiting groove 803 on the rotary feeding mechanism 8 to automatically complete the feeding.

[0023] As a further embodiment of the above invention: the engraving adsorption mechanism 408 includes a connecting plate 4081 fixedly disposed at the bottom end of the second swing arm 407, a pin 4082 inserted through the connecting plate 4081, a mounting plate 4083 fixedly disposed at the bottom end of the pin 4082, a buffer spring 4084 disposed between the mounting plate 4083 and the connecting plate 4081, and a negative pressure suction cup 4085 fixedly disposed at equal intervals at the bottom of the mounting plate 4083. By providing a buffer spring 4084 on the engraving adsorption mechanism 408, the buffering performance of the engraving adsorption mechanism 408 can be effectively improved, and damage caused by violent impact between the negative pressure suction cup 4085 and the engraved part 504 can be avoided when transferring the engraved part.

[0025] As a further embodiment of the above invention: the automatic feeding device 5 includes an outer housing 501, and an engraving part storage slot 502 is equidistantly provided inside the outer housing 501. The engraving part storage slot 502 is provided with a lifting component 503 with sensing function and a workpiece 504 to be engraved. The lifting component 503 with sensing function is located below the workpiece 504 to be engraved. Each time the workpiece 504 to be engraved is moved, the pressing sensor module 7 is triggered once and the sensing signal is sent to the intelligent control terminal 6. The intelligent control terminal 6 can automatically control the lifting component 503 with sensing function to lift upward once, so that the workpiece 504 to be engraved stored in the engraving part storage slot 502 is always at a certain height, so that the workpiece 504 to be engraved can be adsorbed by the engraving part adsorption mechanism 408 at the bottom of the automatic feeding mechanism 4.

[0026] As a further embodiment of the above invention: the press-type sensing module 7, the intelligent control terminal 6, and the lifting component 503 with sensing function are electrically connected.

Each time the workpiece 504 is transferred, the press-type sensing module 7 is triggered once and sends a sensing signal to the intelligent control terminal 6. The intelligent control terminal 6 can automatically control the lifting component 503 with sensing function to lift upward once.

[0027] As a further embodiment of the above invention: the rotary feeding mechanism 8 includes a rotary motor 801 fixedly installed at the bottom of the support platform 1. The rotary motor 801 is fixedly connected to a turntable 802 via a shaft. A limiting groove 803 is provided on the turntable 802. The rotary motor 801 on the rotary feeding mechanism 8 drives the turntable 802 to rotate 120 degrees each time, which can rotate and transport the workpiece 504 to be carved after transfer. When the workpiece 504 is rotated and transported to the bottom of the carving mechanism 3, the workpiece 504 in the limiting groove 803 is quickly carved in multiple positions by multiple sets of laser carving devices 304 provided on the carving mechanism 3. After carving is completed, the rotary motor 801 continues to drive the turntable 802 to rotate 120 degrees. When the carved workpiece 504 rotates to the linkage protrusion 10, the linkage protrusion 10 can push the linkage demolding mechanism 9 upward. After being pushed upward, the linkage demolding mechanism 9 can push the carved workpiece 504 in the limiting groove 803 out of the limiting groove 803 to complete the demolding.

[0028] As a further embodiment of the above invention: an expansion ring component 804 is fixedly provided in the inner cavity of the limiting groove 803. By inflating the expansion ring component 804, the size of the internal space of the limiting groove 803 can be adjusted, and different sizes of the workpiece 504 to be engraved can be positioned.

[0029] As a further embodiment of the above invention: the linkage demolding mechanism 9 includes a lifting slide rod 901, a return spring 902 is sleeved on the outside of the lifting slide rod 901, and a top plate 903 and a linkage plate 904 are respectively provided at the upper and lower ends of the lifting slide rod 901. The bottom end of the linkage plate 904 is provided with a universal roller 905. When the carved workpiece 504 rotates to the linkage protrusion 10, the linkage protrusion 10 can push the linkage demolding mechanism 9 upward. After being pushed upward, the linkage demolding mechanism 9 can push the carved workpiece 504 in the limiting groove 803 out of the limiting groove 803 to complete the demolding.

[0030] As a further embodiment of the above invention: the linkage protrusion 10 is configured as a trapezoidal structure, and the linkage protrusion 10 is located at the top of the support platform 1 near the conveying device 2.

[0031] A method for using a multi-station laser engraving machine includes the following steps: S1. When using, first place the workpiece 504 to be engraved neatly into the engraving workpiece storage slot 502 on the automatic feeding device 5, and then turn on the drive motor 402 on the automatic feeding mechanism 4. When the drive motor 402 rotates in the forward and reverse directions, the first sprocket 403 and the chain 405 can drive the second sprocket 404 to rotate synchronously in the forward and reverse directions. At this time, the first sprocket 403 and the second sprocket 404 can drive the engraving workpiece adsorption mechanism 408 to swing back and forth left and right through the first swing arm 406 and the second swing arm 407. The engraving workpiece adsorption mechanism 408 swings back and forth left and right to quickly transfer the workpiece 504 stored in the automatic feeding device 5 to the limiting slot 803 on the rotary feeding mechanism 8 to automatically complete the feeding. S2. After automatic feeding is completed, the rotary feeding mechanism 8 is opened. The rotary motor 801 on the rotary feeding mechanism 8 drives the turntable 802 to rotate 120 degrees each time, which can rotate and transport the transferred workpiece 504. When the workpiece 504 is rotated and transported to the bottom of the engraving mechanism 3, the multiple sets of laser engraving devices 304 set on the engraving mechanism 3 perform multi-station rapid engraving on the workpiece 504 in the limiting groove 803. After engraving is completed, the rotary motor 801 continues to drive the turntable 802 to rotate 120 degrees. When the engraved workpiece 504 rotates to the linkage protrusion 10, the linkage protrusion 10 can push the linkage demolding mechanism 9 upward. After being pushed upward, the linkage demolding mechanism 9 can push the engraved workpiece 504 in the limiting groove 803 out of the limiting groove 803 to complete the demolding. Then the workpiece 504 is taken away and placed on the conveying device 2 for transport to the next processing program. S3. The number of times the automatic feeding mechanism 4 transfers the workpiece 504 to be engraved can be counted by the press-type sensing module 7. Each time the workpiece 504 to be engraved is transferred, the press-type sensing module 7 is triggered once and the sensing signal is sent to the intelligent control terminal 6. The intelligent control terminal 6 can automatically control the lifting component 503 with sensing function to lift upward once, so that the workpiece 504 stored in the engraving storage tank 502 is always at a certain height, so that the workpiece 504 to be engraved can be adsorbed by the engraving adsorption mechanism 408 at the bottom of the automatic feeding mechanism 4. When the workpiece 504 stored in the engraving storage tank 502 has been transferred, the pressure sensor at the top of the lifting component 503 with sensing function can no longer detect pressure. At this time, the intelligent control terminal 6 will control the alarm system to sound an alarm to remind the staff to add the workpiece 504 to be engraved.

[0032] In this implementation plan: When in use, the workpiece 504 to be engraved is first neatly placed into the engraving workpiece storage slot 502 on the automatic feeding device 5. Then, the drive motor 402 on the automatic feeding mechanism 4 is turned on. When the drive motor 402 rotates in both directions, the first sprocket 403 and the chain 405 can drive the second sprocket 404 to rotate synchronously in both directions. At this time, the first sprocket 403 and the second sprocket 404 can drive the engraving workpiece adsorption mechanism 408 to swing back and forth left and right through the first swing arm 406 and the second swing arm 407. The engraving workpiece adsorption mechanism 408 swings back and forth left and right to quickly transfer the workpiece 504 stored in the automatic feeding device 5 to the limiting slot 803 on the rotary feeding mechanism 8 to automatically complete the feeding. The press-type sensing module 7 can count the number of times the automatic feeding mechanism 4 transfers the workpiece 504 to be engraved. Each time the workpiece 504 is transferred, the press-type sensing module 7 is triggered once and sends a sensing signal to the intelligent control terminal 6. The intelligent control terminal 6 can automatically control the lifting component 503 with sensing function to lift upward once, so that the workpiece 504 stored in the engraving storage tank 502 is always at a certain height, so that the workpiece adsorption mechanism 408 at the bottom of the automatic feeding mechanism 4 can adsorb the workpiece 504 to be engraved. When all the workpieces 504 stored in the engraving storage tank 502 have been transferred, the pressure sensor at the top of the lifting component 503 with sensing function can no longer detect pressure. At this time, the intelligent control terminal 6 will control the alarm system to sound an alarm to remind the staff to add workpieces 504 to be engraved. After automatic feeding is completed, the rotary feeding mechanism 8 is opened. The rotary motor 801 on the rotary feeding mechanism 8 drives the turntable 802 to rotate 120 degrees each time, which can rotate and transport the transferred workpiece 504. When the workpiece 504 is rotated and transported to the bottom of the engraving mechanism 3, the multiple sets of laser engraving devices 304 set on the engraving mechanism 3 perform multi-station rapid engraving on the workpiece 504 in the limiting groove 803. After engraving is completed, the rotary motor 801 continues to drive the turntable 802 to rotate 120 degrees. When the engraved workpiece 504 rotates to the linkage protrusion 10, the linkage protrusion 10 can push the linkage demolding mechanism 9 upward. After being pushed upward, the linkage demolding mechanism 9 can push the engraved workpiece 504 out of the limiting groove 803 to complete the demolding. Then the workpiece 504 is taken away and placed on the conveying device 2 for transport to the next processing program.

10. A method of using a multi-station laser engraving machine, applied to a multi-station laser engraving machine as described in any one of claims 1-9, characterized in that: Includes the following steps: S1. When using, first place the workpiece to be engraved (504) neatly into the engraving storage slot (502) on the automatic feeding device (5), and then turn on the drive motor (402) on the automatic feeding mechanism (4). When the drive motor (402) rotates in the forward and reverse directions, the first sprocket (403) and the chain (405) can drive the second sprocket (404) to rotate in the forward and reverse directions synchronously. At this time, the first sprocket (403) and the second sprocket (404) can drive the engraving adsorption mechanism (408) to swing back and forth through the first swing arm (406) and the second swing arm (407). The engraving adsorption mechanism (408) swings back and forth to quickly transfer the workpiece to be engraved (504) stored in the automatic feeding device (5) to the limiting slot (803) on the rotary feeding mechanism (8) to automatically complete the feeding. S2. After automatic feeding is completed, the rotary feeding mechanism (8) is opened. The rotary motor (801) on the rotary feeding mechanism (8) drives the turntable (802) to rotate 120 degrees each time, which can rotate and transport the workpiece (504) after transfer. When the workpiece (504) is rotated and transported to the bottom of the engraving mechanism (3), the workpiece (504) in the limit groove (803) is quickly engraved by multiple laser engraving devices (304) set on the engraving mechanism (3). After engraving is completed, the rotary motor (801) continues to carry out the engraving. The turntable (802) is rotated 120 degrees. When the carved workpiece (504) rotates to the linkage protrusion (10), the linkage protrusion (10) can push the linkage demolding mechanism (9) upward. After being pushed upward, the linkage demolding mechanism (9) can push the carved workpiece (504) out of the limiting groove (803) to complete the demolding. Then the workpiece (504) is taken away and placed on the conveying device (2) for conveying to the next processing program. S3. The number of times the automatic feeding mechanism (4) transfers the workpiece (504) to be carved can be counted by the press-type sensing module (7). Each time the workpiece (504) to be carved is transferred, the press-type sensing module (7) is triggered once and the sensing signal is sent to the intelligent control terminal (6). The intelligent control terminal (6) can automatically control the lifting component (503) with sensing function to lift upward once, so that the workpiece (504) stored in the carving storage tank (502) is always at a certain height, so that the workpiece (504) to be carved can be adsorbed by the carving adsorption mechanism (408) at the bottom of the automatic feeding mechanism (4). When the workpiece (504) to be carved stored in the carving storage tank (502) is transferred, the pressure sensor at the top of the lifting component (503) with sensing function cannot detect the pressure. At this time, the intelligent control terminal (6) will control the alarm system to remind the staff to add the workpiece (504).
