Description

Technical Field

[0001] This invention relates to the field of spray painting technology, and more specifically to a spray painting equipment and spray painting system. Background Technology

[0002] Spray painting is a process of applying a coating to the surface of an object. Current technology involves spray painting in a closed space, and most spraying is done using robotic arms for multi-angle adjustments. This type of spraying makes it difficult to control the amount of paint applied, so a recycling system is required. Furthermore, it's not convenient to apply different painting strategies to different objects, leading to excessive paint waste. Currently, spray painting requires a large area, often necessitating multiple processes forming an assembly line, which doesn't save labor or floor space, further increasing costs. Moreover, current technology doesn't allow for the establishment of a matching system for control, making it difficult to adapt different painting methods to different shapes. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the primary objective of this invention is to provide a painting device. Before an item enters the machine, a scanning painting unit performs a three-dimensional shape scan to obtain three-dimensional data parameters. Then, a station adjustment unit moves the item to a different position, simultaneously painting the bottom surface of the item. After painting, the three-dimensional data is acquired, and the remaining surfaces are painted using a full-coverage painting unit. The painting angle and position are adjusted based on the three-dimensional data, thus saving paint material and ensuring comprehensive painting, reducing missed areas. The station adjustment unit, in conjunction with an inspection unit, checks the completeness of the painting process. This allows painting to be completed within a single machine, reducing floor space requirements and solving labor cost issues.

[0004] The second objective is to provide a painting system that utilizes a data acquisition module, including a vision sensor, to acquire images of the transported item's shape. These images are then sent to an analysis module, which, upon receiving the images, sends signals for painting the bottom surface and scanning. An execution module then begins painting the bottom surface while simultaneously scanning the item's three-dimensional shape. Once the painting and scanning are complete, the analysis module converts the item's three-dimensional data into coordinates, sending a signal indicating the item is ready to enter the system, along with its coordinates. The execution module then begins painting the remaining surfaces of the item. Upon completion, an end signal is sent, and a re-inspection module checks the painted areas. If the painting is incomplete, a problem signal is sent to the analysis module, which then controls the execution module to return the item to the painting position for touch-up painting. Conversely, if the painting is incomplete, the execution module sends the item out, facilitating coordinated machine control for a painting operation.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a painting system, comprising a data acquisition module, an analysis module, an execution module, and a re-inspection module; the data acquisition module includes a vision sensor, which acquires an image of the object's shape after transportation and sends the image to the analysis module. Upon receiving the image, the analysis module sends a bottom surface painting signal and a scanning signal. The execution module begins bottom surface painting while simultaneously scanning the three-dimensional parameters of the object's shape. After the bottom surface painting signal and scanning are completed, the analysis module analyzes the object's three-dimensional data and converts it into coordinate positions, sending a signal indicating the object is ready to enter and its coordinate position information. The execution module then begins painting the remaining surfaces of the object. After painting is completed, an end signal is sent. The re-inspection module checks the painted positions on the object. If the painting is incomplete, a problem signal is sent to the analysis module, which then controls the execution module to return the object to the painting position for touch-up painting. Conversely, if the painting is incomplete, the execution module sends the object out, thus facilitating coordination with the machine to complete the painting operation.

The data acquisition module 101 includes a vision sensor that acquires an image of the object's shape after it has been transported and sends the image to the analysis module 102. Upon receiving the image, the analysis module 102 sends out a bottom surface painting signal and a scanning signal. The execution module 103 starts bottom surface painting while simultaneously scanning the three-dimensional parameters of the object's shape. After the bottom surface painting signal and scanning are completed, the analysis module 102 analyzes and converts the three-dimensional data of the object. The coordinates are converted into the position of the item, and a signal indicating that the item is ready to enter and its coordinate position information are sent. The execution module 103 begins to spray paint the remaining surface of the item. When the painting is finished, an end signal is sent. The re-inspection module 104 checks the painted position of the item. If the painting is incomplete, a problem signal is sent to the analysis module 102. The analysis module 102 controls the return execution module 103 to return the item to the painting position for repainting.

[0045] Working principle: such as Figure 1-10As shown, during use, the visual sensor collects images of the object's shape after transportation and sends the images to the analysis module (102). After receiving the images, the analysis module (102) sends out a bottom painting signal and a scanning signal. The execution module (103) sends out control commands to start the slide rail 31, causing the two moving blocks 32 to bring the two scanners 31 closer to the object. After the clamping cylinder 34 contacts the object, it pre-clamps the object. The receiving plate 21 is started, causing the object to be pushed upwards a certain distance to leave space for the object to be fully clamped. The servo motor 25 is started, causing the rotating shaft 22 to rotate, turning the painting plate 24 toward the object. Then, the rotating shaft 22 rotates to dry the painting surface with the drying plate 23. The bottom surface is painted simultaneously with the outer surface of the object. After the three-dimensional parameter scanning of the bottom surface is completed, the analysis module (102) analyzes the three-dimensional data of the item and converts it into coordinate position, sends out the signal for the item to enter and coordinate position information, and the execution module (103) starts to issue control commands. First, the turbine reducer 821 with its own power source is started, and then the pulley transmission group 82 drives the main shaft 822 to rotate, thereby starting the preparation for the item to enter. The station motor 85 is started, and then the threaded drive rod 83 rotates, driving the threaded sliding block 84 to slide out, thereby receiving the item, and then resetting. The hydraulic cylinder 42 is started, pushing the protective cover 41 to cover the item, and then the two drive motors 445 are started to adjust according to the obtained coordinate parameters, so that the nozzle 74 that was initially to be sprayed with paint is adjusted. Facing the top of the object, two driven motors 75 are activated simultaneously with the drive motor 43, causing the support frame 441 to rotate. This rotates the two paint adjustment structures 7, completing the side painting. During the painting process, the rack 73 is driven, causing the moving rod to move up and down. It also works in real time with the threaded shaft 443 to adjust the painting position. The telescopic cylinder 71 is used to complete minor detail painting adjustments. While the side is being painted, the active motor 5 is activated, causing the motor shaft 53 to rotate and drive the sliding block 51 to move for top surface painting. This painting is adjusted in real time based on three-dimensional data to conform to the shape of the object. The remaining surfaces of the object are then painted. When the painting is finished, an end signal is issued, activating the self-powered worm gear reducer 821, which then drives the pulley transmission assembly 8. 2 will drive the main shaft 822 to rotate, bringing the item under the accessory part 6. The rotating motor 64 will start, causing the drive gear 63 to drive the gear disk 65 to rotate, thus rotating the item. The telescopic rod 61 will drive the camera 62 to re-inspect the painted surface of the item. The re-inspection module (104) will check the painted position of the item. If the paint is incomplete, it will send a problem signal to the analysis module (102). The analysis module (102) will control the return execution module (103) to return the item to the painted position for repainting. That is, the self-powered turbine reducer 821 will be started. Then the pulley transmission group 82 will drive the main shaft 822 to rotate (reverse). Otherwise, the execution module (103) will send the item out and start the self-powered turbine reducer 821.Then, the belt drive assembly 82 drives the main shaft 822 to rotate, starting the workstation motor 85. The threaded drive rod 83 then rotates, driving the threaded sliding block 84 to slide out and receive the item, before resetting.
