Description

Technical Field

[0001] This utility model relates to the field of spraying technology, specifically to a vehicle painting device based on an RGV vehicle. Background Technology

[0002] In the vehicle manufacturing and repair industry, marking and painting vehicles is a crucial step. With continuous technological advancements, the requirements for the accuracy, efficiency, and adaptability of marking and painting processes are becoming increasingly stringent. Traditional marking and painting methods typically employ mechanical transmission mechanisms to move and position the painting equipment.

[0003] However, in actual production, traditional servo motor rack and pinion mechanisms have gradually revealed many problems. On the one hand, their installation process is relatively complex, requiring high technical requirements and precision. If the mechanism protrudes from the ground, it will seriously affect the normal operation of forklifts and personnel, increasing safety hazards. On the other hand, if the mechanism is buried in the ground, it will create grooves that easily accumulate debris, not only affecting the normal operation of the equipment but also causing great inconvenience to subsequent maintenance work, increasing maintenance costs and time. Alternatively, AGVs can be used to drive 6-axis robots for automatic marking and spraying. However, this method has many problems. First, it requires excessively high ground flatness; even slight undulations in the ground can cause the robot's spray head to fluctuate, affecting the spraying quality. Second, the ground-based auxiliary facilities on which the AGV moves are easily damaged by the working environment, posing operational risks. Third, the sidewall clearance of open wagons is small, requiring high X-axis positioning accuracy, which the AGV's X-axis accuracy cannot meet, easily leading to interference between the spray head and auxiliary facilities. Finally, it is difficult to achieve end-wall marking and spraying by AGVs across tracks.

[0004] Currently, the main solutions to these problems are:

[0005] Optimizing ground flatness is necessary to meet the operational requirements of AGVs and robots. However, this requires large-scale modifications to the existing site, which is costly and disrupts normal production.

[0006] Strengthen the protection and maintenance of ground-based auxiliary facilities. However, in actual operating environments, it is difficult to completely avoid damage to these facilities.

[0007] Optimizing ground flatness fundamentally solves the stability problem of AGV operation, but its disadvantages include high cost, long construction period, and significant impact on production. Strengthening the protection and maintenance of auxiliary facilities is relatively simple and easy to implement, but it cannot fundamentally solve the problem of the vulnerability of auxiliary facilities to damage.

[0008] Taking into account various factors and actual production needs, the RGV trolley and track solution was finally adopted. This solution effectively solved the installation problem of the servo motor gear rack mechanism, avoiding the problems of the mechanism protruding from the ground and affecting operation or being buried in the ground and accumulating debris and causing inconvenience in maintenance. Utility Model Content

[0009] In view of the shortcomings of the existing technology, the technical problem solved by this utility model is to provide a whole vehicle painting device based on RGV trolley, which effectively solves the problem of accurate positioning during painting, avoids the track protruding from the ground, and avoids affecting the passage of forklifts and the normal operation of workers.

[0010] To solve the above problems, the technical solution adopted by this utility model is: a vehicle painting device based on an RGV trolley, characterized in that it includes a worktable with a groove, multiple tracks arranged in the groove, the height of the tracks in the groove not exceeding the horizontal plane of the worktable, and the edge of the groove having an arc-shaped structure; an RGV trolley is arranged on the track, and a robotic arm is arranged on the RGV trolley, the robotic arm being equipped with a painting device and a spraying device; a filter cable is arranged at the lower end of the track, and the RGV trolley is connected for communication through the filter cable.

[0011] The principle of this solution is as follows: The workbench provides a stable working surface. A groove on the workbench accommodates the track, which is lower than the workbench's horizontal plane. This reduces interference with the workspace and lowers the risk of collisions between the track and operators or other objects. The arc-shaped design at the edge of the groove helps to prevent scratches and injuries to objects or personnel, while also facilitating cleaning between the track and the workbench. The RGV trolley runs on the track, moving along it. A filter cable at the bottom of the track provides a stable communication signal for the RGV trolley, enabling it to accurately receive instructions and feedback information, thus precisely reaching the designated position. The sliding mechanism on the RGV trolley increases the range of motion and flexibility of the robotic arm, allowing it to operate at different angles and positions. Driven by the painting and coating devices on the robotic arm, it can perform all-around, multi-angle painting and coating operations on objects on the workbench.

[0012] The beneficial effects of this plan are:

[0013] The worktable is equipped with grooves to accommodate the rails, and the rails are positioned below the horizontal plane of the worktable. This prevents the rails from protruding from the worktable surface, effectively saving workspace and avoiding interference with surrounding operations. At the same time, the rails being lower than the worktable surface better protect them from external damage, reducing the possibility of collisions and debris accumulation, thereby extending the service life of the rails. The RGV carriage on the rails, combined with a sliding mechanism and a robotic arm, greatly enhances the flexibility and operability of the coating device. Furthermore, coating by sliding on the rails allows for better control of the spraying distance and direction.

[0014] Furthermore, a sliding mechanism is provided on the upper surface of the RGV trolley between the robotic arm and the RGV trolley. This sliding mechanism is a horizontal sliding mechanism and is set perpendicular to the sliding direction of the RGV trolley. The sliding mechanism can drive the robotic arm to slide horizontally in a direction perpendicular to the track, thereby increasing the spraying range of the robotic arm and improving the spraying efficiency.

[0015] Furthermore, the spraying device is equipped with multiple spray nozzles arranged in an array. Each spray nozzle is equipped with a solenoid valve, which is electrically connected to a controller located on one side of the spraying device. Each solenoid valve can independently control its corresponding spray nozzle, thereby precisely adjusting the amount of paint sprayed from each nozzle. This achieves fine control over the spraying effect, meeting different spraying needs. The controller can control the opening of different solenoid valves to form different shapes and numbers, and various spraying patterns and fonts can be combined, increasing the diversity and flexibility of spraying.

[0016] Furthermore, a paint spraying device is provided on one side of the spraying device. The nozzles on the paint spraying device and the paint spraying nozzle are on the same plane, and the paint spraying device and the paint spraying device are electrically connected to the controller. According to different work requirements, the controller can easily and flexibly switch between paint spraying and paint spraying without additional manual adjustment, thereby improving work efficiency.

[0017] Furthermore, a distance measuring device and a scanning identifier are respectively installed at both ends of the spraying device. The scanning identifier and the distance measuring device are electrically connected to the controller. The distance measuring device can measure the distance between the spraying device and the surface to be sprayed in real time. The controller can accurately adjust the position of the spraying device and the spraying parameters according to the distance information to ensure the accuracy and uniformity of the spraying. The scanning identifier can identify the spraying surface to avoid mis-spraying.

[0018] Furthermore, charging piles are installed at both ends of the track to charge the RGV trolley. The RGV trolley does not need to return to a specific centralized charging area, saving the time spent on round-trip charging and enabling it to start working more quickly, thereby improving overall production efficiency. The fact that it can be charged at both ends allows the RGV trolley to replenish its power in time when it is low, reducing downtime caused by power depletion and increasing the effective operating time of the equipment.

[0019] Furthermore, a reader is installed on one side of the track. The reader is electrically connected to the controller. The reader can obtain the location information of the carriage that needs to be painted in real time. Based on this, the controller can accurately control the running speed and stopping position of the trolley to ensure that the trolley runs accurately according to the predetermined trajectory and journey.

[0020] Furthermore, the identifier is an AEI identifier, which is set at the position where the carriage enters the workbench. It can obtain relevant information about the carriage, such as the model and number, before the carriage enters the workbench, which facilitates advance preparation and planning for painting, improves work efficiency, and the information obtained at the entrance can be integrated with the data in the subsequent painting process to form a complete painting record, which is convenient for quality traceability and management.

[0021] Furthermore, the cable is a filtered cable, which includes a sheath, an inner conductor, an outer conductor, slots, and an insulator. The inner conductor is covered by the insulator, and the outer conductor is set on the insulator. Multiple slots are set on the outer conductor. The inner conductor being covered by the insulator can effectively reduce signal loss and interference during transmission, ensuring signal strength and purity. The outer conductor can further shield external electromagnetic interference, reduce the impact of external noise on the internal signal transmission of the cable, and improve the stability and reliability of signal transmission.

[0028] The reference numerals in the accompanying drawings include: workbench 1, track 2, RGV trolley 3, sliding mechanism 4, robotic arm 5, charging pile 6, filter cable 7, identifier 8, carriage 9, spraying device 10, controller 11, ranging device 12, spray nozzle 13, painting device 14, solenoid valve 15, scanning identifier 16, outer conductor 17, slot 18, insulator 19, inner conductor 20, groove 21, sheath 22, nozzle 23.

[0029] Example 1 is basically as shown in the appendix. Figure 1-6 As shown: The whole vehicle painting device based on the RGV trolley includes a workbench 1, which provides a stable operating plane for the entire painting operation. The workbench 1 is provided with a groove 21 to accommodate the track 2. The height of the track 2 embedded in the groove 21 is lower than the horizontal plane of the workbench 1, which effectively saves working space and avoids interference with surrounding operations. At the same time, the track 2, which is lower than the table surface, can better avoid damage from external factors, thereby extending the service life of the track 2. Moreover, the edge of the groove 21 is set with an arc structure. Since the RGV trolley 3 is set on the track 2, the roller of the RGV trolley 3 is provided with an edge protrusion between it and the track 2, which can restrict the RGV trolley and prevent it from derailing. Therefore, the RGV trolley 3 can be installed without obstructing the moving objects pushed on the ground. By changing the groove 21 to an arc shape, it is not only convenient for the RGV trolley to move in coordination with the track, but also avoids scratching damage to objects or personnel, and is also easy to clean.

[0030] An RGV trolley 3 is installed on track 2. The RGV trolley 3 can run stably along track 2. A sliding mechanism 4 is installed between the RGV trolley 3 and the robotic arm 5. The sliding mechanism 4 is a sliding mechanism that slides in the direction perpendicular to track 2. The sliding mechanism 4 increases the range of motion of the robotic arm. The sliding mechanism 4 is an electric guide rail. The robotic arm 5 is moved in the direction perpendicular to track 2 through the electric guide rail, thereby increasing the spraying range.

[0031] The robotic arm is equipped with a painting device 14 and a spraying device 10. The spraying device 10 has multiple spray nozzles 13 arranged in a linear array on the spraying device 14. Each spray nozzle 13 is equipped with a solenoid valve 15, which is electrically connected to a controller 11 located on one side of the spraying device 10. This allows the controller 11 to independently and precisely control the amount of paint sprayed from each spray nozzle 13, thereby achieving fine control over the spraying effect and meeting different spraying needs. By controlling the opening of different solenoid valves 15, various spraying patterns and fonts can be created, increasing the diversity and flexibility of the spraying process.

[0032] A painting device 14 is provided on one side of the spraying device 10. The spray nozzle 23 and the spraying nozzle 13 on the painting device 14 are on the same plane. Both the painting device 14 and the spraying device 10 are electrically connected to the controller 11. According to different work requirements, the controller 11 can easily switch between painting and spraying without additional manual adjustment, which significantly improves work efficiency.

[0033] The spraying device 10 is equipped with a distance measuring device 12 and a scanning recognition device 16 at both ends. The scanning recognition device 16 and the distance measuring device 12 are electrically connected to the controller 11. The distance measuring device 12 can measure the distance between the spraying device 10 and the surface to be sprayed in real time. The controller 11 can accurately adjust the position and spraying parameters of the spraying device 10 according to the distance information to ensure the accuracy and uniformity of the spraying. The scanning recognition device 16 can accurately scan and recognize the spraying surface on the vehicle. When the scanning recognition device 16 detects an unsprayed part or a completely sprayed part during scanning and recognition, the scanning recognition device will send a signal back to the spraying device to spray again. The scanning recognition device can be a camera or other paint scanning recognition device.

[0034] Charging piles 6 are installed at both ends of track 2. The charging piles 6 are used to charge the RGV trolley 3, so that the RGV trolley 3 does not need to return to a specific centralized charging area, saving the time of round trip charging, and can be put into work more quickly, improving the overall production efficiency. Moreover, it can be charged at both ends, so when the RGV trolley 3 is low on power, it can be replenished in time, reducing downtime caused by power depletion and increasing the effective operating time of the equipment.

[0035] A reader 8 is installed on one side of track 2. The reader 8 is electrically connected to the controller 11 and is an AEI reader 8. It is set at the position where the carriage 9 enters the workbench 1. Before the carriage 9 enters the workbench 1, it can obtain relevant information such as the carriage model and number, which is convenient for making painting preparation and planning in advance and improving work efficiency. At the same time, the data signal of the carriage that needs to be scanned by the AEI reader 8 is fed back to the controller 11 to form a complete painting record, which is convenient for quality traceability and management.

[0036] In addition, a filter cable 7 is used for communication connection. The filter cable 7 includes a sheath 22, an inner conductor 20, an outer conductor 17, slots 18, and an insulator 19. The inner conductor 20 is covered by the insulator 19, which effectively reduces signal loss and interference during transmission and ensures signal strength and purity. The outer conductor 17 further shields against external electromagnetic interference, reduces the impact of external noise on the internal signal transmission of the cable, and improves the stability and reliability of signal transmission. The multiple slots 18 on the outer conductor 17 play a filtering role and optimize the signal transmission quality.

[0037] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings. However, this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
