[0040] For manufacturing engineering, jigs are metal supports that support products for spraying and prevent thermal deformation of products during drying. As the workpiece is sprayed, the jig will inevitably be covered with paint, eventually forming a layer of hard-to-clean, solidified paint residue, which will affect the placement accuracy and conductivity of the workpiece, further affecting the coating quality and product size of the product. Therefore, the application of jig cleaning methods is an important topic in spraying engineering.
[0041] The current paint removal methods mainly include incineration paint removal, chemical paint removal and laser paint removal. Among them, incineration paint removal and chemical paint removal are mostly used for overall paint removal, while laser paint removal can be used for local paint removal. However, the current method of paint removal for fixtures relies on manually controlled robot movement to remove paint from designated areas on the fixture. Since the areas that need to be painted are different on each fixture, the robot needs to be moved repeatedly in the scene, which is time-consuming and inefficient.
[0042] The present invention provides a paint removal device 100 for a bumper fixture.
[0043] See also Figure 1-Figure 2 In one embodiment of the present invention, the paint removal equipment 100 includes a conveying device 2, a positioning mechanism, a robot 3 and a laser device 4. The conveying device 2 includes a conveying platform 21. The conveying platform 21 is provided with a loading area 22, a first paint removal area 231 and a second paint removal area 232 in sequence along a first horizontal direction. The conveying platform 21 is used to drive the fixture located in the loading area 22 to move to the first paint removal area 231 and the second paint removal area 232 in sequence, wherein the second paint removal area 232 is located at the top of the end of the conveying platform 21 away from the loading area 22, and the first paint removal area 231 is located between the second paint removal area 232 and the loading area 22; the positioning mechanism includes a stopper assembly 26 and a baffle 27, and the stopper assembly 26 is arranged at the conveying platform 21. The baffle 27 is disposed on the conveying platform 21 and is located at a position where the first paint removal area 231 is close to the second paint removal area 232. The baffle 27 is disposed at an end of the conveying platform 21 close to one end of the second paint removal area 232. The stop assembly 26 is used to block the jig on the conveying platform 21 in the first paint removal area 231. The baffle 27 is used to block the jig in the second paint removal area 232. The robot 3 is disposed on one side of the conveying platform 21 along the second horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction. The laser device 4 is disposed on the robot arm 31 of the robot 3, and the robot arm 31 can drive the laser device 4 to move, and output laser through the laser device 4 toward the jig moved to the first paint removal area 231 or the second paint removal area 232 to remove paint from the jig.
[0044] The paint removal device 100 of the present invention uses a conveying device 2 to convey the jig to be removed from the paint to the position of the first paint removal area 231 or the second paint removal area 232, and drives the laser device 4 to move through the robot 3, and outputs a laser toward the jig through the laser device 4 to remove the paint, so that the paint layer on the jig can be effectively removed, and by dividing the working area 23 into the first paint removal area 231 and the second paint removal area 232, the jig can be processed in stages and areas, so that different paint removal tasks can be assigned according to actual needs or different parts of the jig, thereby improving the efficiency and pertinence of the paint removal process; and the jig in the first paint removal area 231 and the second paint removal area 232 can be placed in a plurality of positions. Paint removal is performed between the robot 32, which can ensure that the robot arm 31 can accurately remove paint from different areas on the fixture. For example, when the laser cannot irradiate a certain area of the fixture on the first paint removal area 231, the fixture can be moved to the second paint removal area 232 for paint removal, thereby ensuring a better paint removal effect and avoiding dead corners that cannot be cleaned, thereby increasing flexibility and achieving a better paint removal effect. There is no need to repeatedly move the robot 3, and the fixture can be adjusted between the first paint removal area 231 and the second paint removal area 232 through the conveying device 2, so that the robot 3 can easily adjust the robot arm 31 so that the laser device 4 is aimed at different areas on the fixture for paint removal, and the paint removal efficiency is higher.
[0045] Furthermore, by setting a positioning mechanism, a stop assembly 26 is provided near the first paint removal area 231. The stop assembly 26 can timely block the jig to prevent the jig from moving out of the first paint removal area 231 due to inertia, thereby ensuring the accuracy and stability of the position of the jig and ensuring the paint removal effect. In addition, a baffle 27 is provided at the position corresponding to the second paint removal area 232, which helps to block the jig in the second paint removal area 232 and prevent the jig from falling off the conveyor platform 21.
[0046] When in use, the staff places the jig to be depainted in the loading area 22, and the conveyor table 21 operates to convey the jig to the first paint removal area 231 first. Then, the robotic arm 31 of the robot 3 moves to adjust the position and orientation of the laser device 4, so as to depaint a part of the area on the jig in the first paint removal target; then, the jig is conveyed from the first paint removal area 231 to the second paint removal area 232 by the conveying device 2, and the robotic arm 31 of the robot 3 continues to move to adjust the orientation of the laser device 4, so as to depaint other areas on the jig, thereby completing the paint removal process of the entire jig.
[0047] The robot 3 may be an industrial robot 3 in the prior art, which has a flexible mechanical arm 31 so as to flexibly adjust the position of the laser device 4 .
[0048] like Figure 1 As shown, it should be noted that the first horizontal direction is the front-to-back direction, and the second horizontal direction is the left-to-right direction.
[0049] In one embodiment, two robots 3 are provided, and the two robots 3 are respectively arranged on opposite sides of the conveying platform 21 along the second horizontal direction. A laser device 4 is provided on the mechanical arms 31 of the two robots 3. The two laser devices 4 are respectively used to output lasers toward different areas on the jig moved to the first paint removal area 231 or the second paint removal area 232 for paint removal.
[0050] It can be understood that by setting up two robots 3, and the two robots 3 are respectively set on both sides of the working area 23, each robot 3 is equipped with a laser device 4 on the robotic arm 31, and paint removal treatment can be performed on different areas of the fixture at the same time. This method significantly improves the speed and efficiency of paint removal and reduces the processing time of a single fixture; and because the two laser devices 4 can operate on different areas on the fixture respectively, this helps to ensure that the entire surface of the fixture can be evenly depainted, avoiding the problem of paint residue residue in some difficult-to-reach areas on the fixture, thereby improving the quality of paint removal.
[0051] In one embodiment, the conveying device 2 also includes a mounting frame 25, which is supported on the conveying platform 21. A mounting position is provided on the top of the mounting frame 25, and the mounting position is used to install a jig. The conveying platform 21 can drive the mounting frame 25 to move along the first horizontal direction to drive the jig installed on the mounting frame 25 to move to the first paint removal area 231 or the second paint removal area 232.
[0052] It can be understood that by arranging a mounting frame 25 on the conveyor table 21 and arranging a mounting position for mounting a jig on the top of the mounting frame 25, the loading and unloading operations of the jig can be conveniently performed, and the jig can be stabilized during the transfer process from the loading area 22 to the working area 23 to prevent the jig from shaking and shifting. The mounting frame 25 provides a stable support platform for the jig, which effectively prevents damage to the jig or uneven paint removal due to vibration or displacement during the movement of the jig; at the same time, the stable support also helps to maintain the accuracy of the laser paint removal process; and the mounting frame 25 provides a fixed mounting position, so that the jig placed on the mounting position can maintain a consistent position and posture each time, which helps to ensure that the robot 3 laser device 4 can accurately align with different areas of the jig for paint removal, thereby improving the paint removal accuracy and quality.
[0053] In one embodiment, the mounting frame 25 includes a base plate 251, a support rod 252 and a mounting plate 253; the base plate 251 is supported on the top of the conveying platform 21; the support rod 252 is vertically arranged on the top of the base plate 251; the mounting plate 253 is arranged on the top of the support rod 252, and a mounting position is arranged on the top of the mounting plate 253.
[0054] It can be understood that the bottom plate 251 is directly supported on the top of the conveyor platform 21, providing a stable base for the entire mounting frame 25, and the support rod 252 is vertically arranged on the bottom plate 251 to ensure the vertical stability from the bottom plate 251 to the mounting plate 253. This design makes the overall structure of the mounting frame 25 more solid, can effectively carry the jig, and reduce the instability caused by vibration or movement; at the same time, the mounting frame 25 is supported at a certain height by the support rod 252, ensuring that the jig is supported at a certain height, avoiding the fitting position or dead angle between the jig and the conveyor platform 21 that is not conducive to laser irradiation.
[0055] In one embodiment, the conveying device 2 includes a frame 24 and a rotating driving member 25 disposed on the frame 24. A plurality of rollers 211 are arranged at intervals along a first horizontal direction on the top of the frame 24. The plurality of rollers 211 form a conveying platform 21. The plurality of rollers 211 are arranged for transmission. The rotating driving member 25 is used to drive a roller 211 to rotate, so as to drive the jig to move to the first paint removal area 231 or the second paint removal area 232.
[0056] It can be understood that the conveying platform 21 is formed by multiple rollers 211, and the transmission setting between the multiple rollers 211 can ensure that the various rollers 211 run synchronously and at the same speed, ensuring that the fixture remains stable during the conveying process, and all the rollers 211 can be driven to rotate by a rotating drive member 25 to drive any one of the rollers 211 to rotate.
[0057] Specifically, the rotary driving member 25 may be a driving motor in the prior art.
[0058] Furthermore, the stop assembly 26 is disposed in the gap between two adjacent rollers 211, and the stop assembly 26 includes a lifting mechanism and a stop block 261. The stop block 261 is disposed at the top of the lifting mechanism. The lifting mechanism is used to drive the stop block 261 to rise and fall relative to the roller 211 so as to protrude from the top of the roller 211 to block the jig on the conveying platform 21 in the first paint removal area 231.
[0059] It can be understood that the stop assembly 26 drives the stop block 261 to rise and fall relative to the roller 211 through the lifting mechanism, and can lift the stop block 261 and protrude from the top of the roller 211 when needed, effectively blocking the jig from continuing to move forward, thereby accurately positioning it in the first paint removal area 231. This design can ensure the consistency of the position of the jig during each operation, thereby improving the accuracy of the paint removal operation; and when it is necessary to move the jig to the second paint removal area 232, the lifting mechanism drives the stop block 261 to descend, so that the jig can continue to move with the conveyor table 21 to the second paint removal area 232, and the control is simple and convenient; and the stop assembly 26 is arranged in the gap between two adjacent rollers 211, utilizing the spatial layout of the conveyor table 21 itself, without occupying the additional working area 23, making the entire equipment structure more compact and reasonable, and improving space utilization.
[0060] It should be noted that there is a gap between any adjacent rollers 211, and the stop assembly 26 is arranged in the gap close to the first paint removal zone 231; or it can also be understood that the area on one side of the stop assembly 26 away from the second paint removal zone 232 is the first paint removal zone 231.
[0061] See also Figure 3-Figure 5 In one embodiment, the paint removal equipment 100 also includes a machine room 1, and an entrance 11 is provided on one side of the machine room 1. One end of the conveying platform 21 along the first horizontal direction extends into the machine room 1 from the entrance 11, wherein the loading area 22 is located outside the machine room 1, and the first paint removal area 231 and the second paint removal area 232 are located in the machine room 1.
[0062] It can be understood that by setting the first paint removal area 231 and the second paint removal area 232 in the machine room 1, and the robot 3 is also set in the machine room 1, laser paint removal is performed in the machine room 1, which avoids the risk of laser radiation generated during the operation of the laser device 4 to affect the staff, making it safer and more reliable, and also prevents dust from flying around during the paint removal process.
[0063] In one embodiment, the conveying platform 21 includes two sections that are disconnected and spaced apart from each other, one section is located inside the machine room 1, and the other section is located outside the machine room 1, and the two sections are spaced apart; the machine room 1 is provided with a lifting door at the entrance, and the lifting door can pass through the gap between the two sections vertically. Through the lifting door, the closedness of the machine room 1 can be maintained during the paint removal work, ensuring that the area around the machine room 1 is safer and preventing dust leakage.
[0064] Furthermore, a protective enclosure 13 is provided outside the machine room 1 at a position corresponding to the entrance 11, and the protective enclosure 13 encloses a protective space, and the loading area 22 is located in the protective space. By providing the protective enclosure 13, it is possible to prevent laser radiation and the like from affecting the workers during the paint removal process, prevent irrelevant personnel from entering the operation area, and reduce the occurrence of accidents.
[0065] Furthermore, an explosion vent is provided on the side of the machine room 1 away from the entrance 11, and a flameless explosion vent 14 is provided outside the machine room 1 at a position corresponding to the explosion vent. The explosion vent is designed to provide a way to quickly release pressure when a dust explosion occurs inside the machine room 1, to prevent larger-scale damage or equipment damage caused by pressure accumulation. This design can effectively reduce the degree of damage caused by dust explosions to the structure and internal equipment of the machine room 1. The flameless explosion vent 14 can suppress the spread of flames while discharging high-pressure gas, preventing the fire caused by the explosion from spreading to other areas, thereby preventing possible secondary disasters and improving the overall safety of the equipment.
[0066] In one embodiment, the paint removal equipment 100 also includes an exhaust device 5, which includes an exhaust pipe 51 and a fan 52. The fan 52 is arranged outside the machine room 1. The two ends of the exhaust pipe 51 are respectively connected to the air inlet end of the fan 52 and the machine room 1. The fan 52 is used to draw the gas in the machine room 1 to the outside of the machine room 1.
[0067] By setting up the exhaust device 5, it is connected with the machine room 1 through the exhaust pipe 51. The end of the exhaust pipe 51 away from the machine room 1 is connected with a fan 52. The fan 52 draws air, so that the gas in the machine room 1 can be drawn out of the machine room 1. In particular, during the laser paint removal process, free dust will be generated. Through the exhaust effect of the fan 52, the dust in the machine room 1 can be drawn out of the machine room 1, so as to keep the environment in the machine room 1 good, avoid the risk of dust explosion in the machine room 1, and be more reliable.
[0068] In one embodiment, an exhaust port 12 is provided at the top of the machine room 1, and an exhaust pipe 51 is connected to the exhaust port 12; the exhaust device 5 also includes a filtering mechanism 53, and the filtering mechanism 53 is arranged outside the machine room 1. The air outlet end of the fan 52 is connected to the filtering mechanism 53, and the fan 52 is used to draw the gas in the machine room 1 into the filtering mechanism 53 so that the filtering mechanism 53 can filter the gas.
[0069] By opening an exhaust port 12 at a position corresponding to the working area 23 on the top of the machine room 1 and connecting the exhaust pipe 51 thereto, free particles such as dust generated during the laser paint removal process can be quickly and effectively discharged. This helps maintain the environmental quality in the machine room 1 and also prevents dust from interfering with the normal operation of the robot 3 and the laser device 4. In addition, the gas extracted from the machine room 1 can be filtered through the filter mechanism 53, and the dust obtained by filtering is collected in the filter mechanism 53, so as to prevent the dust from being directly discharged into the external environment and affecting the environment.
[0070] Furthermore, in order to improve the exhaust and dust removal efficiency, two exhaust ports 12 are opened on the top of the machine room 1. Both exhaust ports 12 are connected to the fan 52 through an exhaust pipe 51, which improves the gas extraction efficiency and helps to maintain a good environment in the machine room 1 during the filtration process.
[0071] In one embodiment, a dust monitor for monitoring the dust concentration in the machine room 1 is provided in the machine room 1. By providing the dust monitor, the dust concentration in the machine room 1 is monitored in real time, so that the operation of the exhaust device 5 can be adjusted and controlled in time to avoid dust explosion in the machine room 1. Specifically, the dust monitor can monitor the dust concentration by infrared scattering.
[0072] See also Figure 6 In one embodiment, the laser device 4 includes a laser emitter 41, a transmission optical fiber, and a vibrating lens group 42. The laser emitter 41 is arranged at the end of the robotic arm 31, and the vibrating lens group 42 is arranged at the end of the laser emitter 41 away from the robotic arm 31. The laser emitted by the laser emitter 41 is transmitted to the vibrating lens group 42 through the transmission optical fiber, and the laser is output through the vibrating lens group 42.
[0073] The laser emitter 41 is arranged at the end of the robot arm 31, so that the laser device 4 can reach any position on the fixture through the flexible movement of the robot arm 31. This design greatly improves the flexibility and accuracy of the operation, and is particularly suitable for bumper fixtures with complex shapes or large sizes. The vibrating lens group 42 is located at the end of the laser emitter 41 away from the robot arm 31, and is responsible for focusing and adjusting the direction of the incoming laser beam. This ensures that the laser can form a very small and concentrated spot on the surface of the fixture, thereby realizing a fine and efficient paint removal process. In addition, by adjusting the vibrating lens group 42, the working parameters of the laser, such as focal length and spot size, can be easily changed to meet different paint removal requirements, and the reliability is good.
