[0034] Cleaning room 1;

[0035] A moving mechanism 2, wherein the moving mechanism 2 is arranged in the cleaning room 1, and the moving mechanism 2 comprises a conveying mechanism for moving the workpiece 5 to be stripped of paint and a positioning mechanism for positioning the workpiece 5 to be stripped of paint, wherein the positioning mechanism is arranged at one end of the conveying mechanism close to the robot, and the other end of the conveying mechanism is arranged outside the cleaning room 1; the moving mechanism 2 is used to move the workpiece 5 to be stripped of paint to the corresponding stripping station;

[0036] A laser paint stripping device 3, wherein the laser paint stripping device 3 is arranged in the cleaning room 1, and the laser paint stripping device 3 comprises a robot body 31, a mechanical arm 32 and a laser generating module 33, wherein the mechanical arm 32 is arranged at the robot body 31, and the laser generating module 33 is arranged at one end of the mechanical arm 32, wherein the mechanical arm 32 is used to move the laser generating module 33 to a corresponding paint stripping position, and the laser generating module 33 is used to emit a laser to perform paint stripping on a workpiece 5 to be stripped of paint located at a paint stripping station;

[0037] A control module, wherein the control module is electrically connected to the robot body 31 , the moving mechanism 2 , the safety interlocking module and the laser generating module 33 .

[0038] The laser generating modules that can be used in the embodiments of the utility model include Nd:YAG laser, fiber laser, ultraviolet laser and pulse laser. Nd:YAG laser: The laser wavelength emitted by this laser is 1064nm, which is suitable for removing paint layers from certain metal surfaces. However, for metals with high reflectivity such as aluminum alloys, special attention should be paid to avoid laser damage to the substrate. Fiber lasers have high beam quality and stability and are suitable for precise paint stripping of various materials. In particular, fiber lasers with a wavelength of 1064nm are very suitable for removing paint coatings from the surfaces of metal substrates such as aluminum alloys. When carrying out specific implementation, a pulse laser can be selected, and its power is generally selected to be any value between 2000W and 3000W. The thickness of paint that can be removed is 0-8mm. Specifically, the cleaning depth can depend on the power.

[0039] In the scheme of the embodiment of the utility model, the workpiece 5 to be stripped of paint is mainly multi-layered paint and high-thickness paint in the automobile factory. For example: automobile surface, wheel hub surface, body spraying support fixture, fixture trolley, etc.; when carrying out the specific implementation;

[0040] The industrial robot or the assisting robot cooperates, the main control cabinet reads the product ID information, and the robot selects the corresponding program to cooperate with the laser cleaning machine through the signal to perform full intelligent and automatic varnish removal, thereby reducing labor costs and laser radiation damage to personnel. That is, the system also includes an identification module electrically connected to the control module, and the identification module is used to identify the product information of the workpiece 5 to be depainted, and match the corresponding laser signal according to the product information to achieve efficient automatic cleaning.

[0041] The solution of the utility model realizes the intelligent maintenance pop-up alarm of the laser cleaning machine (including all integrated components of this set of equipment) (when the set operation time is reached, the operator is reminded that a certain component needs to be inspected and maintained and the inspection and maintenance methods are provided), thereby avoiding abnormal damage to the equipment due to untimely maintenance.

[0042] More preferably, it also includes a dust absorption device electrically connected to the control module, wherein the dust absorption device is arranged above the positioning mechanism and is used to absorb the smoke generated after paint stripping.

[0043] More preferably, the dust absorption device includes a dust purification module 8, a purification pipe and a fan module, the dust purification module 8 and the fan are arranged at one end of the purification pipe, and the other end of the purification pipe is arranged above the positioning mechanism for absorbing the smoke generated after paint stripping; the dust purification module 8 is used to purify the air after entering the purification pipe, and the fan module is used to generate negative pressure at the other end of the purification pipe; the diameter of the purification pipe close to the positioning device is the largest.

[0044] The above scheme can effectively absorb the smoke generated during the paint stripping process by setting a dust absorption device, keep the working environment clean, reduce the risk of workers inhaling harmful substances, and also reduce the pollution and damage to the equipment caused by smoke. The dust purification module 8 purifies the air entering the purification pipe, which can effectively remove harmful substances in the air and reduce pollution to the environment. At the same time, by setting a fan module to generate negative pressure at the other end of the purification pipe, smoke can be absorbed more efficiently and energy consumption is reduced. The diameter of the purification pipe near the positioning device is set to the maximum, which can ensure that there is a greater dust absorption capacity in the main area where smoke is generated, that is, near the positioning device, so as to better absorb the smoke.

[0045] More preferably, the dust purification module 8 is an activated carbon filter. When the dust purification module 8 uses an activated carbon filter, the purification effect of the dust absorption device can be significantly improved.

[0046] More preferably, it also includes a smoke sensor electrically connected to the control module, wherein the smoke sensor is arranged in the cleaning space, and the smoke sensor is used to detect the smoke signal in the corresponding space and transmit the smoke signal to the control module so that the control module controls the working state of the dust absorption device.

[0047] The scheme of this embodiment is based on the signal of the smoke sensor, and the control module can intelligently control the working state of the dust absorption device. When the smoke concentration increases, the control module can automatically start or increase the operating power of the dust absorption device to promptly handle the generated smoke and keep the environment clean and safe. The introduction of the smoke sensor improves the safety and reliability of the system. Before a fire occurs or before air pollution exceeds the standard, the system can issue an early warning through the detected abnormal smoke signal, so as to take measures to prevent accidents or mitigate the consequences of accidents. Through intelligent control, the dust absorption device only operates when needed, avoiding unnecessary energy consumption, while also reducing equipment wear and extending its service life. The linkage between the smoke sensor and the control module improves the automation level of the entire paint stripping system, reduces the need for manual intervention, and improves work efficiency.

Flushing with the water mist cooling module can not only reduce the temperature of the workpiece, but also remove the paint stripper or other chemicals remaining on the surface of the workpiece, thereby ensuring the quality and cleanliness of the workpiece.

[0050] The intelligent air curtain machine can quickly dry the workpieces that have been stripped of paint, reduce the time required for the workpieces to dry naturally, and improve production efficiency. At the same time, through intelligent control, the air curtain machine can be started at the appropriate time and temperature to ensure that the workpieces are dried in the best condition and avoid problems such as water stains or rust. Through electrical connection with the control module, the water mist cooling module and the intelligent air curtain machine can be automatically controlled, and automatically start or shut down according to parameters such as the paint stripping progress and temperature of the workpiece, which greatly improves the intelligence level of the production line and reduces the complexity and error rate of manual operation. Both the intelligent air curtain machine and the water mist cooling module can be precisely controlled by the control module to avoid unnecessary energy consumption. At the same time, the water mist cooling module can use a circulating water system to reduce the waste of water resources.

[0052] The conveying mechanism includes a first conveying mechanism and a second conveying mechanism.

The second conveying mechanism is used to convey the movable plate 4 to the first conveying mechanism. The positioning mechanism includes a first positioning column 24 and a second positioning column.

[0053] By providing a storage table 43 on the movable plate 4, and a fixing clamp 431 on the storage table 43, the workpiece 5 to be stripped of paint can be tightened and fixed more effectively. This design not only ensures that the workpiece remains stable during the conveying and stripping process, reduces the risk of the paint stripping effect being affected by the movement or shaking of the workpiece, but also improves the accuracy and safety of the overall operation. By providing a first conveying mechanism and a second conveying mechanism, a smooth and efficient conveyance of the workpiece from the outside to the inside of the cleaning room 1 is achieved. The second conveying mechanism is responsible for conveying the movable plate 4 with the workpiece from the outside to the first conveying mechanism in the cleaning room 1, and then the first conveying mechanism accurately conveys the workpiece to the paint stripping station. This segmented conveying design improves the conveying efficiency and accuracy of the workpiece.

[0054] The positioning mechanism of the first positioning column 24 and the second positioning column can ensure that the movable plate 4 and the workpiece thereon can be accurately aligned with the paint stripping station. This dual positioning design further enhances the accuracy and repeatability of the paint stripping process, which is of great significance for improving the overall paint stripping quality and efficiency.

[0055] The design of the embodiment of the utility model allows the system to flexibly handle workpieces of different sizes and weights, just by adjusting the storage table 43 and the fixing clamp 431. At the same time, if the system needs to be expanded or adjusted in the future, this modular design is also easier to transform and upgrade, providing more plasticity.

[0056] The optimized design of the mobile mechanism 2 of this embodiment can reduce manual intervention and make the overall paint stripping process smoother and more efficient.

[0061] The first baffle 23 is arranged between the two first transmission chains 22, and plays the role of aligning the movable plate 4 to ensure that the movable plate 4 does not deviate from the track or tilt during the transmission process.

This design greatly improves the positioning accuracy and consistency of the paint stripping process. The number of positioning columns here is not fixed, it can be one, it can be two, or even three.
