[0002] Paint stripping is the process of removing old or unwanted paint from the surface of metal, wood or other materials. This process is often done to repair a damaged surface, refurbish an old item or prepare it for repainting.

[0003] In the prior art, sandblasting is a widely used paint removal method, which uses compressed air to spray abrasives (such as sand, glass beads or other abrasives) onto the surface of the workpiece at high speed, thereby effectively removing the paint layer and other dirt. However, when only one specific surface of the workpiece needs to be depainted, traditional sandblasting may bring additional problems. Because it is difficult to accurately control the direction and range of the abrasive during the sandblasting process, it is easy for the abrasive to splash onto other surfaces that do not need to be depainted, thereby causing unnecessary wear or damage to them.

DETAILED DESCRIPTION

[0015] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0016] like Figures 1 to 3 As shown, a laser paint removal device for a workpiece of the present invention comprises: a frame 1; a conveyor belt 2, which is movably arranged on the frame 1 and is used to transport the workpiece; a paint removal component 3, which has a paint removal part 4 located above the moving path of the workpiece, and the paint removal part 4 is used to remove paint on the surface of the workpiece; a dust suction component 5, which is arranged on the frame 1 and is used to clean the residue on the surface of the workpiece and the dust on the conveyor belt 2; a central control unit 6, which is arranged on the frame 1 and is electrically connected to the paint removal component 3 and the dust suction component 5, and is used to control the operation of the paint removal component 3 and the dust suction component 5.

[0017] In actual operation, the workpiece is first placed on the conveyor belt 2; as the conveyor belt 2 runs smoothly, the workpiece will be transported to the preset working position. When the workpiece reaches this preset position, the central control unit 6 will start and play a key role. It will accurately control the paint removal component 3, and the paint removal component 3 will drive the paint removal component 4 to move closer to the workpiece until the paint removal component 4 reaches the preset paint removal position. At this time, the paint removal component 4 starts to remove the paint from the workpiece, effectively removing the paint on the specified surface. During the entire paint removal process, the central control unit 6 is not only responsible for monitoring the action of the paint removal component 3, but also synchronously starting the dust suction component 5, which will continuously vacuum the workpiece and its conveyor belt 2 in time. Remove the residues and dust generated during the paint removal process to ensure a clean and safe working environment; this paint removal method only removes the paint on a specific surface of the workpiece, and will not have any impact on other surfaces of the workpiece that do not need to be processed, thereby ensuring the overall integrity of the workpiece and the quality of subsequent processing. In addition, by using a conveyor belt 2 to transport the workpiece, and combining with the central control unit 6, the paint removal part 4 automatically approaches the workpiece and performs the paint removal task under the drive of the paint removal component 3, the entire process is highly automated; this design not only improves production efficiency, but also reduces the need for manual intervention, and is very suitable for application in modern manufacturing production lines, especially those industries that pursue efficient and precise production.

[0018] Specifically, the paint removal component 4 is a laser head, which is used to perform laser paint removal on the workpiece. It can accurately control the emission and focusing of the laser beam. Due to the high concentration of laser energy, the paint removal process can be carried out in a very small range, thereby ensuring that only the designated workpiece surface is processed without affecting other parts that do not require paint removal.

[0019] Specifically, the paint removal component 3 also includes: a support base 7, which is arranged on the frame 1; a driving member 8, at least one driving member 8 is arranged on the support base 7; a connecting block 9, which is arranged at the output end of the driving member 8, and the laser head is connected to the connecting block 9, and the driving member 8 drives the laser head to rise and fall through the connecting block 9; when the conveyor belt 2 transports the workpiece to the preset position, the central control unit 6 accurately controls the driving member 8 to start, and the driving member 8 drives the laser head to descend to the preset paint removal position through the connecting block 9, and then starts the paint removal work. This working method greatly improves the automation level of the paint removal operation, wherein the driving member 8 can be a cylinder, a cylinder or a motor.

[0020] Specifically, the dust suction component 5 includes: a main body 10, which is provided on both sides of the conveyor belt 2; a dust suction port 11, which is provided on the main body 10, and the dust suction port 11 is arranged opposite to the conveyor belt 2, and is used to collect residues on the surface of the workpiece and dust on the conveyor belt 2. When the laser head removes paint from the workpiece, the central control unit 6 simultaneously controls the dust suction component 5 to work, so that the residues and dust generated during the paint removal process enter the main body 10 through the dust suction port 11, thereby ensuring the cleanliness and safety of the working environment.

[0021] In order to facilitate the operator to input control instructions to the central control unit 6, a set of input devices 12 is also arranged on the frame 1. Signal transmission is realized between the set of input devices 12 and the central control unit 6 through electrical connection, so that the operator can conveniently send instructions to the central control unit 6 through the input device 12, thereby realizing precise control of the entire system. In addition, the input device 12 can be a mouse and a keyboard.

[0022] In order to fix the input device 12, a fixing plate 13 is provided on the frame 1, and the input device 12 is connected to the fixing plate 13. Such a design not only improves the convenience of use for operators, but also ensures the safety of the input device 12 and the orderliness of the system layout, thereby improving the efficiency of the entire control system.

[0023] Specifically, a mounting groove 14 is provided on the side wall of the frame 1, and the fixing plate 13 is hinged on one side of the mounting groove 14 and can be moved on the mounting groove 14 to a closed or open position. The closed position can protect the input device 12 from external influences, while the open position is for facilitating the operation of the staff.
