Description

Technical Field

[0001] This application relates to the field of materials processing, and in particular to a multi-head paint stripping device. Background Technology

[0002] In the modern lighting field, the paint stripping process for automotive headlights plays a crucial role. With the rapid development of the new energy vehicle industry, market demand for personalized and functional new energy vehicles is increasing. Headlights, as a vital component of new energy vehicles, play a key role in enhancing their attractiveness and recognizability through their unique lighting effects. By spraying a protective paint layer onto the headlight surface to form a protective film, and then peeling off this film according to a pre-designed pattern, diverse lighting designs can be achieved, satisfying consumers' pursuit of personalized vehicles.

[0003] In existing related technologies, paint stripping equipment typically includes a clamping and positioning mechanism, a dust removal mechanism, a top laser mechanism, and two side laser mechanisms working together to complete the paint stripping operation. Specifically, the operator places the vehicle headlight in the clamping and positioning mechanism according to a preset posture. This mechanism precisely clamps and positions the headlight, ensuring that the surface to be processed is fully exposed, preparing it for subsequent paint stripping. The top laser emission mechanism is positioned directly above the headlight, while the two side emission mechanisms are arranged on the sides of the three-dimensional headlight. To achieve effective paint stripping from different locations on the headlight, both the top laser emission mechanism and the two side emission mechanisms employ a three-axis motion system. This system allows the laser head to move flexibly along the X, Y, and Z axes, enabling precise stripping of paint from various parts of the headlight to achieve the desired preset pattern.

[0004] However, existing paint stripping equipment has significant drawbacks. Firstly, the use of three three-axis motion systems to complete the entire stripping process results in a complex structure, requiring precise coordination and cooperation between the various motion systems, leading to significantly increased maintenance costs and a larger equipment size that occupies more production space. Secondly, because the headlights have a V-shaped structure with a significant height difference, to avoid interference between the various laser mechanisms, the two side laser emitters typically only begin working simultaneously after the top laser emitter has finished its work and exited the working area. This sequential working method greatly prolongs the stripping time and reduces stripping efficiency. Summary of the Invention

[0005] To meet the design requirements of miniaturization and high efficiency of equipment, simplify the equipment structure, reduce the size of the equipment, and improve the paint stripping efficiency of vehicle lights, this application provides a multi-head paint stripping device.

[0006] This application provides a multi-head paint stripping device, including a frame, a support mechanism disposed on the frame, and a laser mechanism. The support mechanism includes a mounting base, a support platform, a clamping assembly, a flipping drive component, and a Y-axis linear drive module. The flipping drive component is fixedly disposed on the mounting base to drive the support platform to flip around a horizontal axis. The clamping assembly is fixedly disposed on the support platform to clamp a vehicle light. The Y-axis linear drive module drives the mounting base to reciprocate along the Y-axis direction. The laser mechanism includes an X-axis linear drive module, three Z-axis linear drive modules, and three laser heads. The three Z-axis linear drive modules are spaced apart from the X-axis linear drive module so that the three Z-axis linear drive modules can move to different positions along the same X-axis. The three laser heads are respectively disposed on the three Z-axis linear drive modules so that the three laser heads can be raised and lowered to different heights independently. The three laser heads are respectively used to process the left section, the bent section, and the right section of the vehicle light.

[0007] By adopting the above technical solution and using multi-area parallel processing, three laser heads can simultaneously peel paint off three areas of the headlight. The three laser heads are independently controlled on the Z-axis and share a common X-axis movement, simplifying the mechanical structure and motion control, making the movement smoother and more efficient. Specifically, since the headlight has a V-shaped three-dimensional structure, the support platform can be driven to rotate around the horizontal axis through the flip drive component of the support mechanism, which can easily adjust the angle of the headlight. This, combined with the laser mechanism, allows for a more comprehensive paint peeling operation on each section of the headlight, shortening the processing time. The Y-axis linear drive module drives the mounting base to move back and forth along the Y-axis, allowing the headlight to change position in the Y-axis direction, which is beneficial for the laser head to accurately process the paint in different locations. The laser mechanism's three Z-axis linear drive modules are spaced apart on the X-axis linear drive module, allowing them to move to different positions along the same X-axis and process paint peeling on different parts of the headlight along the X-axis. The three laser heads are each mounted on one of the three Z-axis linear drive modules and can be independently raised and lowered to different heights, adapting to varying height differences in different sections of the headlight. Each laser head is specifically designed to process the left, curved, and right sections of the headlight, allowing for simultaneous paint peeling on different sections. Compared to the sequential multi-axis drive control of existing laser technologies, this design significantly reduces peeling time and improves efficiency. Furthermore, it eliminates the need for multiple complex three-axis motion systems, simplifying the equipment structure, reducing maintenance costs, decreasing equipment size, and saving production space.

[0008] Preferably, the flipping drive includes a flipping motor, which is fixedly connected to the mounting base. A horizontally arranged rotating shaft is fixedly connected to the bottom of the support platform. The rotating shaft rotates relative to the mounting base. The output end of the flipping motor is fixedly connected to the rotating shaft.

[0009] By adopting the above technical solution, the tilting motor is fixedly connected to the mounting base, and the rotating shaft at the bottom of the support platform rotates relative to the mounting base and is fixedly connected to the output end of the tilting motor. When the tilting motor starts, the rotation of its output end drives the rotating shaft to rotate. Since the rotating shaft is fixedly connected to the support platform, the support platform rotates around the horizontal axis. In this way, the posture of the car head held on the support platform can be flexibly adjusted, so that the paint at different positions of the car head can be better exposed within the processing range of the laser head. This avoids the problem of some paint being difficult to process due to the fixed posture of the car head, and improves the comprehensiveness and accuracy of paint stripping.

[0010] Preferably, the support platform is a U-shaped plate structure with a U-shaped groove. The clamping assembly is fixedly installed on the platform surface away from the U-shaped groove. A fixing hole is opened on the side wall of the support platform near the opening of the U-shaped groove. The rotating shaft is fixedly installed in the fixing hole. The mounting base has a through hole coaxially arranged with the fixing hole. The rotating shaft passes through the through hole and can rotate relative to the through hole.

[0011] By adopting the above technical solution, the support platform uses a U-shaped plate structure with a U-shaped groove. This structure reduces the weight of the support platform itself, decreases the driving force required by the flipping drive component to rotate the support platform around the horizontal axis, and reduces energy consumption. Furthermore, the U-shaped groove design makes the support platform's structure more rational and enhances its stability. A clamping assembly is fixedly installed on the platform surface away from the U-shaped groove, enabling convenient and stable clamping of the vehicle light. A fixing hole is made on the side wall of the support platform near the U-shaped groove opening, and a rotating shaft is fixed therein. Simultaneously, a through hole coaxial with the fixing hole is made on the mounting base, allowing the rotating shaft to pass through and rotate relative to it. This structural design provides stable rotational support for the rotation of the support platform around the horizontal axis, making the rotation process more stable and smooth.

[0012] Preferably, the clamping assembly includes at least two clamping members, each of which includes a fixed base, a clamping cylinder, and a pressing block. The fixed base is disposed on the table surface of the support platform, the clamping cylinder is fixedly disposed on the fixed base and its output end is perpendicular to the table surface of the support platform, and the output end of the clamping cylinder is fixedly connected to the pressing block.

[0013] By adopting the above technical solution, at least two such clamping components can clamp the headlight from different positions. The multiple clamping points allow the headlight to be subjected to a more even force, avoiding damage caused by uneven force at a single point. This improves the stability and reliability of the headlight clamping, ensuring that the headlight will not shake or shift during the paint stripping process, and guaranteeing that the paint stripping work can be carried out accurately and smoothly.

[0014] Preferably, there are two clamping components, which are spaced apart along the Y-axis, and each clamping component can clamp one vehicle light individually.

[0015] By adopting the above technical solution, and by setting up two clamping components spaced apart along the Y-axis, with each clamping component capable of clamping one headlight individually, the multi-head paint stripping device can simultaneously clamp and fix two headlights. Compared to devices that can only clamp a single headlight, more headlights can be processed in a single paint stripping operation, reducing the waiting time caused by loading and unloading headlights, thereby greatly improving the overall paint stripping efficiency.

[0016] Preferably, each laser head has two emission points spaced apart along the Y-axis, and the distance between the two emission points is adapted to the distance between the midpoints of the two vehicle lights.

[0017] By adopting the above technical solution, since each laser head has two emission points spaced along the Y-axis, and the distance between the two emission points is adapted to the distance between the midpoints of the two car lights, the two emission points of each laser head can be aligned with the two car lights simultaneously during one processing cycle. This avoids the tedious steps of processing each car light one by one in the traditional method, reduces the time for the laser head to switch positions between different car lights, and thus improves the paint stripping efficiency of the multi-head paint stripping equipment.

[0018] Preferably, the fixing seat is detachably installed on the platform of the support.

[0019] By adopting the above technical solution, the mounting base can be detachably installed on the support platform. When the clamping components need to be repaired, replaced, or the installation position adjusted according to different models of vehicle lights, the mounting base can be easily removed from the support platform without complicated operations on the entire support mechanism. This effectively reduces the time and workload required for maintenance and adjustment, and improves the ease of equipment maintenance.

[0020] Preferably, the laser mechanism further includes three controllers, each of which can control the movement trajectory of one of the laser heads.

[0021] By adopting the above technical solution, and by setting up three controllers to control the movement trajectory of each laser head, the movement of each laser head can be independently and precisely controlled. Compared with the complex coordination required by multiple laser mechanisms in existing technologies, this independent control method avoids mutual interference between laser heads, and since there is no overlap or duplication among the three areas, the three laser heads can work simultaneously. The movement trajectory of each laser head can be flexibly adjusted according to the paint stripping requirements of different sections of the vehicle headlight (left section, bend section, right section), thereby improving the accuracy and efficiency of paint stripping, while also reducing the difficulty and cost of equipment maintenance.

[0022] Preferably, the laser mechanism further includes three displacement sensors, which are configured one-to-one with the three Z-axis linear drive modules to monitor whether the displacement of the corresponding Z-axis linear drive module exceeds a preset area and to feed back to the respective controller.

[0023] By adopting the above technical solution, three displacement sensors are set up, each corresponding to one of the three Z-axis linear drive modules, allowing real-time monitoring of the displacement of each Z-axis linear drive module. During operation, the displacement sensors accurately capture displacement data and determine whether the displacement exceeds a preset area. If the displacement exceeds the preset area, the sensor quickly feeds this information back to its corresponding controller. Upon receiving the feedback, the controller promptly adjusts the movement of the Z-axis linear drive module to prevent it from exceeding the safe range. This ensures the stability and accuracy of the laser head during processing, reduces processing errors caused by abnormal displacement of the Z-axis linear drive modules, and improves the processing quality and reliability of the multi-head paint stripping equipment.

[0024] Preferably, it also includes a dust removal mechanism, which is disposed on the frame and includes a plurality of suction pipes, the air inlet of each suction pipe facing the position between the laser head and the workpiece.

[0025] By adopting the above technical solution, when the multi-head paint stripping equipment is working, the laser head generates paint debris and other contaminants during the paint stripping operation. Since the dust removal mechanism is located on the frame and the air inlets of its several suction pipes are all directed towards the area between the laser head and the workpiece, the suction pipes can promptly remove the contaminants generated during the paint stripping process when the equipment is running. This prevents contaminants from accumulating in the processing area, ensuring a clean processing environment, reducing the impact of contaminants on the laser head and workpiece, improving the quality of paint stripping, and also benefiting the health of operators by reducing the health risks caused by inhaling contaminants.

[0026] In summary, the beneficial technical effects of this application are as follows: Using one X-axis linear drive module and three Z-axis linear drive modules to control three laser heads, it is possible to simultaneously process the left, curved, and right sections of the vehicle headlight without interference. Simultaneously, the rotating drive component of the support mechanism can drive the support platform to rotate around the horizontal axis, and the Y-axis linear drive module can drive the mounting base to reciprocate along the Y-axis. Compared to the three three-axis motion systems in the prior art, this reduces the number of motion systems, simplifies the equipment structure, and lowers maintenance costs. It also makes the overall equipment more compact, reducing its size and thus minimizing production space occupation. Furthermore, it changes the sequential working method of the prior art, where the two side laser emission mechanisms only begin working simultaneously after the top laser emission mechanism has finished its work and exited the working area. This allows for simultaneous paint stripping of different parts of the vehicle headlight, and the synchronous operation of multiple parts greatly shortens the time required for paint stripping and improves stripping efficiency.

[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] This application provides a multi-head paint stripping device, referring to... Figure 1 It includes a frame 1, a support mechanism 2 set on the frame 1, a laser mechanism 3 and a dust removal mechanism 4. The support mechanism 2 and the laser mechanism 3 cooperate with each other. The support mechanism 2 is used to support and position the vehicle lights, and the laser mechanism 3 is used to perform paint stripping operations on the vehicle lights.

[0031] Reference Figure 1 and Figure 2Specifically, the support mechanism 2 in this embodiment includes a mounting base 21, a support platform 22, a clamping assembly 23, a flipping drive component 24, and a Y-axis linear drive module 25. The mounting base 21 serves to support and connect other components. The support platform 22 is used to place the vehicle light. The support platform 22 is a U-shaped plate structure with a U-shaped groove, which can better adapt to the shape of the vehicle light and provide stable support. The clamping assembly 23 is fixedly installed on the platform surface of the support platform 22 away from the U-shaped groove. The clamping assembly 23 is used to clamp the vehicle light to ensure that the vehicle light will not move during the paint peeling process.

[0032] The clamping assembly 23 includes three clamping components, each comprising a fixed base 231, a clamping cylinder 232, and a clamping block 233. The fixed base 231 is mounted on the surface of the support platform 22 and can be detachably installed on the platform, facilitating adjustment and replacement according to different headlight sizes and shapes. The clamping cylinder 232 is fixedly mounted on the fixed base 231 with its output end perpendicular to the platform of the support platform 22. The output end of the clamping cylinder 232 is fixedly connected to the clamping block 233. When the clamping cylinder 232 operates, it pushes the clamping block 233 towards the headlight, thereby clamping the headlight.

[0033] The number of clamping components 23 can be set according to actual processing requirements. In this embodiment, two clamping components 23 are set, and the two clamping components 23 are spaced apart along the Y-axis. Each clamping component 23 can clamp one car light individually, so that the paint stripping operation of two car lights can be performed at the same time, improving work efficiency.

[0034] The rotating drive component 24 is fixedly mounted on the mounting base 21 to drive the support platform 22 to rotate around a horizontal axis. The rotating drive component 24 is a rotating motor, which is fixedly connected to the mounting base 21. The bottom of the support platform 22 has a fixing hole, in which a horizontal rotating shaft 26 is fixedly mounted. The mounting base 21 has a through hole through which the rotating shaft 26 can rotate relative to the mounting base 21. The output end of the rotating motor is fixedly connected to the rotating shaft 26. When the rotating motor works, it drives the rotating shaft 26 to rotate, thereby causing the support platform 22 to rotate around the horizontal axis. This allows adjustment of the headlight angle, facilitating the laser mechanism 3 to peel off paint from different locations on the headlight. The rotating shaft 26 can be made of high-strength alloy steel to ensure it can withstand the weight of the support platform 22 and the headlight. The rotating shaft 26 and the mounting base 21 can be connected by bearings to reduce friction and improve rotational flexibility.

[0035] The Y-axis linear drive module 25 drives the mounting base 21 to reciprocate along the Y-axis direction. The Y-axis linear drive module 25 uses a lead screw and nut transmission to achieve linear motion. Driven by the Y-axis linear drive module 25, the mounting base 21 can move the support platform 22 and the headlight in the Y-axis direction, causing the headlight to reciprocate in the Y-axis direction, facilitating the laser mechanism 3 to peel off paint from different locations on the headlight. Simultaneously, the flip drive component 24 rotates the headlight, adjusting its angle so that the laser can better cover all areas of the headlight.

[0036] Reference Figure 3 and Figure 4 Specifically, the laser mechanism 3 in this embodiment includes an X-axis linear drive module 31, three Z-axis linear drive modules 32, three laser heads 33, three controllers 34, and three sensors 35. Since the headlight shape is roughly divided into three areas—left, curved, and right—three laser heads 33 are used to peel paint from each of these three areas separately. This parallel processing method allows operations that would normally require processing different areas sequentially to be performed simultaneously, greatly reducing waiting time caused by sequential processing and thus significantly shortening the overall processing time.

[0037] The X-axis linear drive module 31 drives three Z-axis linear drive modules 32 to move along the same X-axis to different positions. The three Z-axis linear drive modules 32 are spaced apart from the X-axis linear drive module 31. The three laser heads 33 share a single X-axis movement, ensuring that the laser heads 33 can move collaboratively along the length of the headlight to cover the entire headlight surface, while reducing the complexity of the mechanical structure and the number of moving parts. Compared to each laser head 33 having an independent X-axis movement mechanism, this design reduces equipment costs and the difficulty of motion control, reduces coordination problems that may arise from multiple independent X-axis movements, and makes the movement of the laser heads 33 in the X-axis direction smoother and more efficient, helping to shorten processing time.

[0038] The three Z-axis linear drive modules 32 are used to drive the three laser heads 33 to rise and fall to different heights, respectively, since the three laser heads 33 correspond to the left, curved, and right sections of the headlight. The three laser heads 33 move along their independent Z-axis, allowing for independent and precise adjustment of the distance between the laser head 33 and the paint surface according to the specific shape and curvature of each area of ​​the headlight surface. This ensures that each laser head 33 is always at the optimal working distance, removing the paint surface with the most suitable energy and focus, avoiding the possibility of insufficient or excessive processing in some areas due to uniform Z-axis adjustment, thus improving the processing efficiency of each area and shortening the overall processing time. Each laser head 33 has two emission points spaced along the Y-axis, with the distance between the two emission points matching the distance between the midpoints of the two headlights. This allows for simultaneous paint stripping operations on two headlights, improving work efficiency.

[0039] The system includes three controllers 34, each capable of controlling the movement trajectory of a laser head 33. Under the control of the controllers 34, the laser head 33 can peel away the paint from the headlights according to a preset pattern. Each Z-axis linear drive module 32 is equipped with a sensor 35 to monitor whether the displacement of its corresponding Z-axis linear drive module 32 exceeds a preset area and to provide feedback to its respective controller 34. When the sensor 35 detects that the displacement of the Z-axis linear drive module 32 exceeds the preset area, it sends a signal to the corresponding controller 34, which then adjusts the movement trajectory of the laser head 33 to prevent interference between the laser head 33 and other components.

[0040] Specifically, in this embodiment, the dust removal mechanism 4 is installed on the frame 1. The dust removal mechanism 4 includes several suction pipes 41 and a suction pump. The air inlet of each suction pipe 41 faces the position between the laser head 33 and the workpiece. During the laser paint stripping process, a large amount of dust and smoke are generated. Turning on the suction pump of the dust removal mechanism 4 can remove this dust and smoke through the suction pipes 41, keeping the working environment clean and also helping to improve the quality of paint stripping.

[0041] The implementation principle of this embodiment is as follows: The multi-head paint stripping device in this embodiment achieves precise peeling of paint from different positions of the vehicle headlight through the cooperation of the support mechanism 2 and the laser mechanism 3. The clamping component 23 of the support mechanism 2 can stably clamp the vehicle headlight, and the flipping drive component 24 and the Y-axis linear drive module 25 can adjust the position and angle of the vehicle headlight, facilitating the paint stripping operation of the laser mechanism 3. The three laser heads 33 of the laser mechanism 3 can strip paint from the left, bent, and right sections of the vehicle headlight respectively. The parallel processing method reduces the waiting time of sequential processing. The movement of each laser head 33 along an independent Z-axis can accurately adjust the distance from the paint surface, and the shared X-axis movement reduces the complexity of the mechanical structure and the difficulty of motion control, greatly improving the paint stripping efficiency. In addition, the setting of the controller 34 and the sensor 35 can ensure the accuracy of the movement trajectory of the laser head 33 and avoid interference between the laser head 33 and other components. The setting of the dust removal mechanism 4 can maintain the cleanliness of the working environment and improve the paint stripping quality. Compared with the prior art, the device structure of this embodiment is simpler, the number of motion systems is reduced, maintenance costs and device size are reduced, and the parallel operation mode is adopted, which shortens the paint stripping time and improves the paint stripping efficiency.

[0042] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
