[0043] In the present application, unless otherwise specified, the orientation words such as "up, down, top, bottom" are generally directed to the direction shown in the drawings, or are directed to the vertical, perpendicular or gravity direction of the components themselves; similarly, for the convenience of understanding and description, "inner, outer" refers to the inner and outer of the contour of each component itself, but the above orientation words are not used to limit the present application. EMBODIMENT

[0044] Referring to Figs. 1-3 The laser scribing device shown in the drawings includes a rack 1, a moving unit, a laser module 7, a suction dust removal unit, etc., and each part of the assembly cooperates to efficiently and accurately complete the scribing operation on the workpiece to be processed.

[0045] The rack 1 is the main support structure of the device, which has good stability and load-bearing capacity. A grid-shaped bearing table 2 is provided thereon, and a suction table 3 is arranged on the bearing table 2. The upper surface of the suction table 3 is a plane, which can ensure that the workpiece to be processed is placed stably, and provides good conditions for subsequent scribing operation.

[0046] The carrying table 2 in this embodiment is constructed by welding square tubes, which are tightly connected by welding process to form a stable grid structure. The carrying table composed of square tubes not only has sufficient strength and rigidity to support the adsorption table 3 and the workpiece to be processed, but also has good ventilation, which helps heat dissipation and airflow circulation of the equipment, ensuring stable operation of the equipment.

[0047] The moving unit is the key part of the equipment to realize precise positioning and marking. The moving unit includes X-axis linear motor module 4, Y-axis linear motor module 5 and Z-axis linear motor module 6. The X-axis linear motor module 4 is symmetrical arranged on both sides of the adsorption table 3, and the first slider of the two X-axis linear motor modules 4 is provided with a cross beam, and the Y-axis linear motor module 5 is arranged on the cross beam, and the second slider of the Y-axis linear motor module 5 is provided with a vertical load plate, and the Z-axis linear motor module 6 is arranged on the vertical load plate. Through the cooperative work of the X, Y and Z linear motor modules, the precise positioning of the laser module 7 in the three-dimensional space can be realized, so as to meet the marking requirements of different positions and angles.

[0048] The laser module 7 as the core processing component is arranged on the third slider of the Z-axis linear motor module 6 through the conversion plate. The laser beam emitted by it has the characteristics of high energy density and high precision, and can perform accurate marking operation on the workpiece to be processed.

[0049] The adsorption and dust removal unit plays an important role in the operation of the equipment. The suction backpack 8 is fixedly arranged on the rack 1 on one side of the X-axis linear motor module 4, and the suction cavity in the suction backpack 8 provides a negative pressure environment for dust removal. The long strip-shaped adsorption body 9 arranged on the cross beam of the Y-axis linear motor module 5 is uniformly provided with a plurality of dust suction ports 91 facing the side of the laser module 7. The suction backpack 8 and the adsorption body 9 are connected by a plurality of telescopic air pipes, so that the dust suction ports 91 are communicated with the suction cavity. When the vacuumizing equipment is working, the suction backpack 8 is connected with the vacuumizing equipment through the air pipe adapter 10, a negative pressure is formed in the suction cavity, so that the dust and waste gas generated in the marking process are sucked into the dust suction ports 91 and discharged through the telescopic air pipe and the air pipe adapter 10, effectively ensuring the cleanliness of the working environment and the normal operation of the equipment.

[0050] In this embodiment, the upper and lower edges of the dust suction port 91 are respectively provided with an upper baffle 92 and a lower baffle 93, which are locked on the adsorption body 9 by screws. Specifically, the upper baffle 92 adopts a downward inclined bending design, and the lower baffle 93 adopts an upward inclined bending design. This structural layout naturally encloses an auxiliary cavity in the outer side area of the dust suction port 91. The existence of the auxiliary cavity can effectively intercept and block the dust particles that are not completely sucked in during the dust removal operation, preventing them from directly falling into the working environment, thereby significantly reducing the secondary pollution problem caused by dust scattering.

[0051] In addition, the laser scribing device is also equipped with a control system, a power supply system, a gas supply system, a vacuum pumping system, etc., and through unified interface and operation instructions, the collaborative work of each link is realized, thereby providing a strong guarantee for the automatic production of the device.

[0052] In the embodiment, the front surface of the adsorption table 3 is uniformly distributed with a plurality of adsorption holes, which are regularly arranged to ensure uniform and stable adsorption of the workpiece to be processed. The bottom of the adsorption table 3 is provided with an air exhaust port, which is connected in communication with an external air exhaust device. An adsorption cavity is arranged in the adsorption table 3, which is connected in communication with the air exhaust port and each adsorption hole. When the air exhaust device is working, a negative pressure is formed in the adsorption cavity, so that the workpiece to be processed is firmly adsorbed on the front surface of the adsorption table 3 under the action of atmospheric pressure, thereby providing a stable basis for subsequent laser scribing operation.

[0053] In the embodiment, the X-axis linear motor module 4 includes a first linear motor extending along the X-axis direction and two first linear guides matched with the first linear motor. The two first linear guides are symmetrically distributed on the two sides of the first linear motor, thereby providing stable guiding for the module. The first linear motor itself is composed of a first stator and a first mover, wherein the first mover is fixedly connected with a first sliding block, and the first sliding block is slidingly connected with the first linear guide. This connection mode ensures that when the first linear motor operates, the first mover can drive the first sliding block to slide along the first linear guide accurately, thereby realizing position adjustment in the X-axis direction.

[0054] In the Y-axis direction, the Y-axis linear motor module 5 undertakes the corresponding movement task. The module includes a second linear motor arranged on the cross beam and extending along the Y-axis direction, and two second linear guides. Similar to the X-axis module, the two second linear guides are respectively located on the upper and lower sides of the second linear motor, thereby providing stable guiding for movement in the Y-axis direction. The second linear motor is composed of a second stator and a second mover, wherein the second mover is fixedly connected with a second sliding block, and the second sliding block is slidingly connected with the second linear guide. When the second linear motor starts, the second mover drives the second sliding block to slide along the second linear guide, thereby realizing accurate position control in the Y-axis direction.

[0055] As for the Z-axis linear motor module 6, it is responsible for height adjustment in the Z-axis direction. The module includes a third linear motor arranged on the vertical loading plate and extending along the Z-axis direction. The third linear motor is composed of a third stator and a third mover, wherein the third mover is fixedly connected with a third sliding block. When the third linear motor operates, the third mover drives the third sliding block to move in the Z-axis direction, thereby accurately adjusting the height position of the laser module 7, and ensuring that the laser beam can be accurately focused on the material to be cut.

[0056] The laser module 7 in this embodiment includes a laser and an altimeter. The laser is used to emit a laser beam to cut the material to be cut, and the altimeter is used to measure the distance between the laser module 7 and the material to be cut in real time, and transmit the measurement data to the control system, so that the control system adjusts the Z-axis position of the laser module 7 according to the distance information, ensures that the focal point of the laser beam always accurately falls on the material to be cut, and improves the cutting precision and quality.

[0057] The rack 1 is the basic support structure of the whole device, and the outer shell 11 is arranged thereon, which is made of high-strength and corrosion-resistant metal material, not only beautiful and generous, but also more importantly, can comprehensively cover and protect the internal mobile unit and the core components such as the laser module 7, effectively prevent dust, moisture, foreign matters and the like in the external environment from invading, and ensure the long-term stable operation of the device.

[0058] The design of the outer shell 11 fully considers the convenience of operation and maintenance, and the switch door 12 and the maintenance door 13 are specially arranged thereon. The switch door 12 is used for daily operation and control, and is convenient for users to quickly access the device to make necessary operation adjustment, and the maintenance door 13 is specially designed for maintenance and repair of the device, and when the device needs internal inspection or component replacement, the maintenance door 13 can be easily opened to provide sufficient operation space for the technicians.

[0059] In order to operate safely, sensors for monitoring whether the switch door 12 and the maintenance door 13 are in an open state are arranged in the outer shell 11. These sensors are electrically connected with the control system, and once it is detected that the door body is abnormally opened, an alarm or an automatic shutdown mechanism will be triggered immediately, effectively preventing safety accidents caused by misoperation or unauthorized access.

[0060] In addition, considering the transportation and installation requirements of the device, a plurality of lifting rings 14 are specially designed on the top of the outer shell 11, which are made of high-strength alloy material and can bear the overall weight of the device, and ensure the stability and safety during hoisting, and provide strong support for the rapid deployment and flexible movement of the device.

[0061] The utility model discloses a linear motor module is used to move the laser module, and this design is compared to the traditional screw module, and the response speed is fast, and the positioning precision is high. The adsorption main part 9 can move along with the laser module 7 and carry out dust collection processing to the dust generated by the laser module 7 marking operation in real time, to avoid its pollution working environment.
