Description

TECHNICAL FIELD

[0001] The utility model relates to a paint removing technology field especially relates to a laser paint removing equipment. BACKGROUND

[0002] For manufacturing engineering, the jig is a metal support for supporting the product for spraying and preventing product thermal deformation during drying. With the continuous spraying of the workpiece, the coating will inevitably cover the jig, and finally form a layer of difficult-to-clean, solidified paint slag. This layer of paint slag will affect the placement accuracy and conductive state of the workpiece, thereby further affecting the coating quality and product size. Therefore, the application of the jig cleaning method is an important issue in the spraying engineering.

[0003] The current paint removing methods mainly include the following methods: 1. Direct incineration method: put the dirty jig directly into the incinerator for incineration, and make the paint slag powder by high temperature combustion. After incineration, cooling and washing are performed. The disadvantage is that the incineration of paint slag containing a large amount of VOC will cause a significant increase in the VOC content of the exhaust gas, which is difficult to apply in places with low environmental regulation limits. The jig will be deformed after incineration, and needs to be repaired and corrected after each cleaning. For jigs that need to be repeatedly used, the reliability is poor. 2. Chemical cold soaking method: put the jig into a water tank containing cold stripping chemicals, wait for the paint slag to fully react, and then take out the jig for washing. The disadvantage is that the cold stripping chemicals have high biological toxicity, which has high operation risk, and the cost of cold stripping chemicals is high, so the cleaning cost is also high. 3. Chemical hot stripping method: put the jig into a water tank containing hot stripping chemicals, wait for the paint slag to fully react, and then take out the jig for washing. The disadvantage is that the hot stripping chemicals have certain corrosive properties, which has high operation risk, and additional heating is required during cleaning, so the cleaning cost is high.

[0042] For manufacturing engineering, the jig is a metal support for supporting the product for spraying and preventing the product from being deformed during drying. As the workpiece is continuously sprayed, the jig will inevitably be covered with paint, and eventually a layer of hardened paint residue will be formed, which will affect the placement accuracy and conductivity of the workpiece, and further affect the coating quality and product size. Therefore, the application of the jig cleaning method is an important issue for the spraying engineering.

[0043] The current paint removal methods mainly include the following methods: 1. Direct incineration method: by directly putting the dirty jig into the incinerator for incineration, the paint residue is pulverized by high temperature combustion, and then cooled and washed after incineration. The disadvantage is that the paint residue containing a large amount of VOC is incinerated, which will cause the VOC content of the exhaust gas to rise sharply, and it is difficult to apply in places where environmental regulations are limited. The jig will be deformed after incineration, and needs to be repaired and corrected after each cleaning. For jigs that need to be used repeatedly, the reliability is poor. 2. Chemical cold soaking method: put the jig into a water tank containing cold stripping chemicals, wait for the paint residue to fully react, and then take out the jig for washing. The disadvantage is that the cold stripping chemicals have high biological toxicity, have high operation risk, and the cost of cold stripping chemicals is high, so the cleaning cost is high. 3. Chemical hot stripping method: put the jig into a water tank containing hot stripping chemicals, wait for the paint residue to fully react, and then take out the jig for washing. The disadvantage is that the hot stripping chemicals have certain corrosive properties, have high operation risk, and need to be heated during cleaning, so the cleaning cost is high.

[0044] Because the jig needs to be used repeatedly, the above-mentioned several paint removal methods have the problems of poor reliability and high cost.

[0045] The utility model provides a kind of laser paint removal equipment 100.

[0047] The utility model discloses a laser paint removal equipment 100, by adopting robot 3 drive laser device 4 moves, and through laser device 4 towards the jig output laser carries out paint removal, can effectively remove the paint layer on the jig, compared with using traditional paint removal mode, laser not only can not cause the deformation of jig, and reliability is good, and can carry out paint removal treatment to the local area of the paint layer on the jig, and laser device 4 can be repeatedly used, is suitable for long -term use, and the cost is lower.

[0048] And, by conveying device 2, the jig needing paint removal is placed on conveying device 2, is transported to machine room 1 by conveying device 2, carries out laser paint removal in machine room 1, avoids the influence of laser radiation risk produced in the working process of laser device 4 to the staff, and safety is more reliable, and still is equipped with exhaust device 5, and exhaust pipe 51 is communicated with machine room 1, and the one end of exhaust pipe 51 away from machine room 1 is connected with fan 52, and the gas in machine room 1 can be extracted to outside machine room 1 by fan 52, especially in the process of laser paint removal, will produce free dust, by the effect of fan 52, the dust in machine room 1 can also be extracted to outside machine room 1, keeps the environment in machine room 1 good, avoids the risk of dust explosion in machine room 1, and is more reliable.

[0049] In use, the worker places the jig to be stripped in the loading area 22, the conveying table 21 is operated to convey the jig to the working area 23, then the robot 3 near the working area 23 is actuated to adjust the position and orientation of the laser device 4 through the mechanical arm 31, so as to strip different positions on the jig; after the stripping of the jig is completed, the jig can also be conveyed from the working area 23 to the loading area 22 through the conveying device 2, and then the worker takes down the jig from the loading area 22.

[0050] It should be noted that in the present embodiment, the jig is taken as an example of a bumper jig, and in some other embodiments, the laser stripping device 100 can also be applied to process other product jigs.

[0051] Among them, the robot 3 can adopt an industrial robot 3 in the prior art, which has a flexible mechanical arm 31 to flexibly adjust the position of the laser device 4.

[0052] As shown in Figure 4 In an embodiment, two robots 3 are provided, and the two robots 3 are respectively arranged on opposite sides of the conveying table 21 along a second horizontal direction, the second horizontal direction being perpendicular to the first horizontal direction, and the mechanical arms 31 of the two robots 3 are respectively provided with laser devices 4, and the two laser devices 4 are respectively used to output laser to different areas on the jig located in the working area 23 for stripping.

[0053] It can be understood that by providing two robots 3 and arranging the two robots 3 on both sides of the working area 23, the mechanical arm 31 of each robot 3 is equipped with a laser device 4, so that different areas of the jig can be stripped at the same time. This way significantly improves the stripping speed and efficiency and reduces the processing time of a single jig; and since the two laser devices 4 can operate on different areas of the jig, it helps to ensure that the entire surface of the jig can be uniformly stripped, avoiding the problem of paint residue in some hard-to-reach areas of the jig, thereby improving the stripping quality.

[0054] Further, the position of the robot 3 is fixed relative to the conveying device 2 to ensure sufficient stability of the mechanical arm when in motion.

[0055] As shown in Figure 4 It should be noted that the first horizontal direction is the front-rear direction, and the second horizontal direction is the left-right direction.

[0056] As shown in Figure 4 and Figure 5As shown, in an embodiment, the conveying device 2 further comprises a mounting rack 25 supported on the conveying table 21, and a mounting position for mounting the jig is arranged on the top of the mounting rack 25; the conveying table 21 can drive the mounting rack 25 to move along the first horizontal direction, so as to drive the jig mounted on the mounting rack 25 to move to the working area 23.

[0057] It can be understood that, by arranging the mounting rack 25 on the conveying table 21 and arranging the mounting position for mounting the jig on the top of the mounting rack 25, the mounting and dismounting operation of the jig can be conveniently performed, the transfer process of the jig from the feeding area 22 to the working area 23 is stabilized, the jig is prevented from shaking and moving, the mounting rack 25 provides a stable support platform for the jig, and the problem of damage or uneven paint removal of the jig caused by vibration or movement during the movement of the jig is effectively prevented; at the same time, the stable support is also helpful to maintain the accuracy during the laser paint removal process; and the mounting rack 25 provides a fixed mounting position, so that the jig placed on the mounting position each time can maintain consistent position and posture, which is helpful to ensure that the laser device 4 of the robot 3 can accurately align different areas of the jig for paint removal treatment, thereby improving the paint removal accuracy and quality.

[0058] In an embodiment, the mounting rack 25 comprises a bottom plate 251, a support rod 252 and a mounting plate 253; the bottom plate 251 is supported on the top of the conveying table 21; the support rod 252 is arranged on the top of the bottom plate 251 in a vertical direction; and the mounting plate 253 is arranged on the top of the support rod 252, and the top of the mounting plate 253 is provided with the mounting position.

[0059] It can be understood that the bottom plate 251 is directly supported on the top of the conveying table 21, which provides a stable base for the entire mounting rack 25, and the support rod 252 is arranged on the bottom plate 251 in a vertical direction, which ensures the vertical stability between the bottom plate 251 and the mounting plate 253. This design makes the overall structure of the mounting rack 25 more stable, which can effectively bear the jig and reduce the unstable factors caused by vibration or movement; at the same time, the mounting rack 25 is supported at a certain height by the support rod 252, which ensures that the jig is supported at a certain height, avoiding the existence of the sticking position or dead angle between the jig and the conveying table 21 which is not conducive to laser irradiation.

[0060] In an embodiment, the working area 23 comprises a first paint removal area 231 and a second paint removal area 232 arranged adjacent to each other along the first horizontal direction, the second paint removal area 232 is located at the top of the conveying table 21 at the end away from the feeding area 22, and the first paint removal area 231 is located between the second paint removal area 232 and the feeding area 22; the conveying table 21 is provided with a stop component 26, and the stop component 26 is located at the side of the first paint removal area 231 close to the second paint removal area 232, and the stop component 26 is used to block the jig on the conveying table 21 in the first paint removal area 231; the end of the conveying table 21 close to the second paint removal area 232 is provided with a baffle 27, and the baffle 27 is used to block the jig in the second paint removal area 232.

[0061] It can be understood that 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 regions, which can allocate different paint removal tasks according to actual needs or different parts of the jig, thereby improving the efficiency and pertinence of the paint removal process; and the jig is painted in the first paint removal area 231 and the second paint removal area 232, which can ensure that the mechanical arm 31 can accurately paint different regions of the jig, such as when the laser cannot irradiate a certain region of the jig in the first paint removal area 231, the jig can be moved to the second paint removal area 232 for paint removal, thereby ensuring better paint removal effect and avoiding dead angles that cannot be cleaned, increasing flexibility and improving paint removal effect.

[0062] In addition, the stop component 26 is arranged at the position close to the first paint removal area 231, which can timely block the mounting frame 25 and prevent the mounting frame 25 from moving out of the first paint removal area 231 under the action of inertia, thereby ensuring the accuracy of the position of the jig on the mounting frame 25 and ensuring the paint removal effect; in addition, the baffle 27 is arranged corresponding to the position of the second paint removal area 232, which helps to block the jig in the second paint removal area 232 and prevents the jig from falling off the conveying table 21.

[0063] In an embodiment, the conveying device 2 comprises a rack 24 and a rotating drive 25 arranged on the rack 24, the top of the rack 24 is spaced apart along the first horizontal direction and provided with a plurality of rollers 211, the plurality of rollers 211 form a conveying table 21, and the plurality of rollers 211 are transmissionally arranged, the rotating drive 25 is used to drive one roller 211 to rotate to move the jig to the working area 23.

[0064] It can be understood that the plurality of rollers 211 form the conveying table 21, and the plurality of rollers 211 are transmissionally arranged, which can ensure that each roller 211 runs synchronously and at the same speed, and the jig can be kept stable during conveying, and driving any one roller 211 to rotate by the rotating drive 25 can drive all rollers 211 to rotate.

[0065] Specifically, the rotary drive 25 may be a drive motor as used in the prior art.

[0066] Furthermore, the stop assembly 26 is disposed in the gap between two adjacent rollers 211. The stop assembly 26 includes a lifting mechanism and a stop block 261. The stop block 261 is disposed on 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, so as to block the fixture on the conveyor table 21 in the first paint removal area 231.

[0067] Understandably, the stop assembly 26, through a lifting mechanism, drives the stop block 261 to rise and fall relative to the roller shaft 211. When needed, the stop block 261 can be raised and protrude above the top of the roller shaft 211, effectively blocking the fixture from moving forward and thus accurately positioning it in the first paint removal zone 231. This design ensures the consistency of the fixture's position during each operation, improving the accuracy of the paint removal operation. When it is necessary to move the fixture to the second paint removal zone 232, the lifting mechanism drives the stop block 261 to fall, allowing the fixture to continue moving with the conveyor table 21 to the second paint removal zone 232. The control is simple and convenient. Furthermore, the stop assembly 26 is set in the gap between two adjacent roller shafts 211, utilizing the space layout of the conveyor table 21 itself, without occupying the work area 23, making the entire equipment structure more compact and reasonable, and improving space utilization.

[0068] Specifically, there is a gap between any two adjacent rollers 211, and the stop assembly 26 is set in the gap near the first paint removal zone 231; or it can be understood that the area of ​​the stop assembly 26 away from the second paint removal zone 232 is the first paint removal zone 231.

[0069] In one embodiment, the conveyor 21 includes two sections that are disconnected from each other and spaced apart, one section being located inside the machine room 1 and the other section being located outside the machine room 1, with the two sections spaced apart; the machine room 1 is provided with a lifting door at the entrance, which can pass vertically through the gap between the two sections. Through the lifting door, the machine room 1 can be kept closed during paint removal work, ensuring greater safety around the machine room 1 and preventing dust leakage.

[0070] like Figure 3 As shown, in one embodiment, an exhaust port 12 is provided on the top of the computer room 1 at the position corresponding to the work area 23, and an exhaust pipe 51 is connected to the exhaust port 12; the exhaust device 5 also includes a filter mechanism 53, which is located outside the computer room 1, and the exhaust end of the fan 52 is connected to the filter mechanism 53. The fan 52 is used to draw the gas in the computer room 1 into the filter mechanism 53 so that the filter mechanism 53 can filter the gas.

[0071] It can be understood that by opening the exhaust port 12 at the top of the machine room 1 corresponding to the position of the working area 23, and connecting the exhaust pipe 51 thereto, the dust and other free particulate matter generated during the laser paint removal process can be quickly and effectively discharged. This helps to maintain the environmental quality inside the machine room 1, and also avoids dust interfering with the normal operation of the robot 3 and the laser device 4. Moreover, by filtering the gas extracted from the machine room 1 through the filtering mechanism 53, the dust filtered out can be collected in the filtering mechanism 53, avoiding the direct discharge of dust into the external environment to affect the environment.

[0072] Further, in order to improve the dust removal efficiency of the exhaust, two exhaust ports 12 are opened at the top of the machine room 1, both of which are connected to the fan 52 through an exhaust pipe 51, improving the gas extraction efficiency and helping to maintain a good environment inside the machine room 1 during the filtering process.

[0073] Please continue to refer to Figure 2 In an embodiment, a protective enclosure 13 is also provided outside the machine room 1 corresponding to the position of the inlet 11, and the protective enclosure 13 encloses a protective space, and the loading area 22 is located in the protective space. It can be understood that by providing the protective enclosure 13, the influence of laser radiation during paint removal on the workers can be avoided, and unrelated personnel can be prevented from entering the operating area, reducing the occurrence of accidents.

[0074] In an embodiment, an explosion vent is also provided on the side of the machine room 1 away from the inlet 11, and a flameless explosion venting device 14 is provided outside the machine room 1 corresponding to the position of the explosion vent.

[0075] It can be understood that the explosion vent is designed to provide a way to quickly release pressure when a dust explosion occurs inside the machine room 1, preventing larger-scale damage or equipment damage caused by pressure accumulation. This design can effectively reduce the damage caused by dust explosion to the structure of the machine room 1 and the internal equipment, and the flameless explosion venting device 14 can suppress the spread of flames while discharging high-pressure gas, preventing the spread of fire caused by explosion to other areas, thereby preventing possible secondary disasters and improving the overall safety of the equipment.

[0076] As Figure 6 shown, in an embodiment, the laser device 4 includes a laser emitter 41, a transmission optical fiber, and a vibration lens group 42, the laser emitter 41 is arranged at the end of the mechanical arm 31, the vibration lens group 42 is arranged at the end of the laser emitter 41 away from the mechanical arm 31, the laser emitted by the laser emitter 41 is transmitted to the vibration lens group 42 through the transmission optical fiber, and the laser is output through the vibration lens group 42.

[0077] The laser transmitter 41 is arranged at the end of the mechanical arm 31, so that the laser device 4 can reach any position on the jig through the flexible movement of the mechanical arm 31. This design greatly improves the flexibility and accuracy of operation, especially suitable for complex-shaped or large bumper jigs. The vibration lens group 42 is located at the end of the laser transmitter 41 away from the mechanical arm 31, responsible for focusing and direction adjustment of the incoming laser beam. This ensures that the laser can form a very small and concentrated spot on the jig surface, thereby achieving a fine and efficient paint removal process. In addition, by adjusting the vibration lens group 42, the working parameters of the laser such as focal length and spot size can be easily changed to adapt to different paint removal needs, with good reliability.

[0078] The above is only an exemplary embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation or direct / indirect application in other related technical fields within the technical concept of the present application, as described in the present application and the attached drawings, is included in the patent protection scope of the present application.
