Description

Technical Field

[0001] The utility model relates to the technical field of paint spraying equipment, in particular to a paint rapid spraying device. Background Art

[0002] In the process of paint spraying, in order to ensure that the spraying operation is carried out quickly and evenly, the corresponding spraying machine is often used to replace manual spraying. The basic principle is that after the object to be sprayed is placed in the spraying machine and fixed, the spraying component of the spraying equipment moves evenly around the surface of the object to be sprayed and sprays the paint according to the pre-set program. Compared with manual spraying, the advantage of mechanical spraying is that it can accurately control the distance between the nozzle and the object to be sprayed, as well as the amount of material discharged during spraying. However, mechanical spraying still has the problem that the size of the object to be sprayed needs to match the range of the spraying machine's operating area, that is, the spraying machine has a better spraying effect for objects with specific sizes, such as objects with smooth surfaces, and for related special-shaped objects, such as objects or operating areas with irregular or curved surfaces, the spraying machine may be difficult to use. Even if it can be barely used, the irregular spraying surface will cause a significant decrease in spraying uniformity and rate. This is also one of the important reasons why manual spraying is still irreplaceable compared to mechanical spraying. Utility Model Content

[0016] The present invention will be further described in detail below in conjunction with the embodiments and drawings.

[0017] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

[0018] Example:

[0019] See also Figure 1 A paint rapid spraying device,

[0020] It includes a paint spray box 1, a base 2, a base linear motor 3, a lift 4, a linear motor 5, a paint spray head 6, a laser rangefinder 7, and a PLC controller 8. The rectangular base 2 is provided with a paint spray box 1 for pumping paint through an internal air pump 11 and base linear motors 3 arranged in pairs. The moving direction of the base linear motor 3 is perpendicular to the side of the base 2. Lifts 4 are arranged in pairs on the base linear motor 3. The movable part of the lift 4 is connected with a linear motor 5 whose moving direction is perpendicular to the base linear motor 3. The base linear motor 3 can drive the lift 4 to move on the base 2 under the control of the control station, and the lift 4 can drive the linear motor 5 to move up and down under the control of the control station. The linear motor 5 itself can move in the horizontal direction parallel to the moving direction of the base linear motor 3. It can be seen that the linear motor 5 can realize three-axis movement under the action of the control station.

[0021] The linear motor 5 is provided with a paint spray head 6 which is perpendicular to the moving direction of the linear motor 5 in the horizontal plane and whose nozzle points to the outside of the base 2. The laser rangefinder 7 is arranged on the linear motor 5 close to the paint spray head 6, and its probe is parallel to the nozzle of the paint spray head 6, so that the paint spray head 6 and the laser rangefinder 7 can also realize three-axis movement. The paint spray head 6 is connected to the paint spray joint 9 on the paint spray box 1 which is connected to the pumping pipeline. The paint spray head 6 is connected to the pumping pipeline inside the paint spray box 1 through the paint spray joint 9 pipeline. The working ports of the paint spray head 6 and the laser rangefinder 7 are both pointing to the outside of the base 2. When working, the overall position of the device is adjusted so that the paint spray head 6 and the laser rangefinder 7 point to the object to be painted. When painting, the laser rangefinder 7 will monitor in real time. The distance between the paint spray head 6 and the working surface will remain unchanged for objects with uniform working surfaces, but for objects to be painted with irregular working surfaces, such as a wind barrier with a C-shaped structure, after the laser rangefinder 7 detects that the distance between the paint spray head 6 and the working surface has changed during the movement of the paint spray head 6 for painting, the distance signal is sent to the control station, which analyzes the difference between the current distance between the paint spray head 6 and the working surface and the set working distance. The control station controls the base linear motor 3 to move a corresponding distance to compensate for the difference, and the laser rangefinder 7 feeds back a signal to the control station in real time to ensure that the paint spray head 6 always maintains a set distance from the working surface, thereby achieving uniform painting.

[0022] The PLC controller 8 is arranged outside the paint spray box 1, and is electrically connected to the base linear motor 3, the lift 4, the linear motor 5, the paint spray head 6, the laser rangefinder 7 and the air pump 11 respectively. The PLC controller 8 is the control station used in this embodiment. The program editing method in the prior art can be referred to. The editing program controls the lift 4 and the linear motor 5 to move at a certain speed and trajectory, and further makes the paint spray head 6 and the laser rangefinder 7 move evenly. The movement program is independent of the base linear motor 3. The base linear motor 3 is feedback-regulated by the laser rangefinder 7 and the PLC controller 8, thereby realizing the distance control between the paint spray head 6 and the working surface during the painting operation.

[0023] See also Figure 2 In this embodiment, a paint spray box door 13 is provided on the surface of the paint spray box 1, and an air pump 11 and a paint tank 12 are respectively provided inside the paint spray box 1. The paint tank 12 is detachably arranged inside the paint spray box, and is connected to the air pump 11 and the paint spray joint 9 pipeline in sequence. The air pump 11 is controlled by the PLC controller 8 to continuously and evenly transport the paint in the paint tank 12 along the pipeline where the paint spray joint 9 is located to the paint spray head 6 for spraying. The paint tank 12 is a detachable structure, which is convenient for opening the paint spray box door 13 for replacement after the paint is exhausted.

[0024] In this embodiment, universal wheels 10 are provided on the base 2 for supporting and moving the base 2, so that the device as a whole can be moved. During real-time painting operations, the device can be moved to an appropriate distance from the paint head 6 and the laser rangefinder 7 facing the work surface to start the operation.

[0025] In this embodiment, the two contact ends of the linear motor 5 and the lifter 4 are respectively hinged with retractable positioning rods 14, and the retractable mode of the positioning rod 14 is damped retractable. On the horizontal plane, the positioning rod 14 can rotate between a position perpendicular to the moving direction of the linear motor 5 and a position parallel to the moving direction of the linear motor 5. When in use, the positioning rod 14 is rotated to Figure 1 In the direction perpendicular to the movement of the linear motor 5, the function of the positioning rod 14 is to facilitate the determination of the distance between the device and the working surface. In the vertical state, its damping extends to contact the working surface, and the distance between the paint head 6 and the working surface can be quickly obtained by measuring the length of the positioning rod 14 at this time; on the other hand, the positioning rod 14 can be used to locate the painting range of longer objects: when the device stops at a certain position to spray paint the object, the painting range in the direction of movement of the linear motor 5 is the distance between the two sets of positioning rods 14 in this direction. After that, the device is moved as a whole so that the positioning rod 14 moves to a position that just corresponds to the edge of the painting range, and the range that can be newly operated at this time can be obtained, and the painting operation can be performed on the block. Through this positioning block operation method, the working area can be sprayed only once, avoiding repeated spraying of the adjacent areas between the two blocks to affect the uniformity of the spraying.

[0026] When using, Figure 1 The device shown is moved to the fixed object to be painted, so that the paint head 6 and the laser rangefinder 7 are aligned with the object. At the same time, a positioning rod 14 rotated to a vertical position is used to assist in measuring the horizontal distance between the paint head 6 and the laser rangefinder 7 and the surface of the object. According to the optimal distance for painting, the horizontal distance between the entire device and the object is adjusted, and the program is edited in the PLC controller 8 to obtain the measurement limit of the laser rangefinder 7. When the measured value is not equal to the limit, the PLC controller 8 can move the base linear motor 3 accordingly according to the size of the actual measured value to ensure that the distance between the paint head 6, the laser rangefinder 7 and the projection point on the object is always equal to the measurement limit.

[0027] Then, according to the size of the object, the corresponding program is edited in the PLC controller 8, and the continuous moving range of the elevator 4 and the linear motor 5 is set, that is, the working range of the paint spray head 6. The PLC controller 8 controls the air pump 11 to output paint and perform the painting operation.

[0028] There are two types of painting operations. One is continuous operation, which is suitable for special-shaped objects with limited length and relatively regular curved surfaces. That is, the elevator 4 and the linear motor 5 maintain the continuous moving state set by the program, and the paint head 6 sprays paint continuously to complete the painting of the entire object. During this process, when the laser rangefinder 7 detects that the measured value is equal to the measurement limit, the PLC controller 8 adjusts the distance between the paint head 6 and the object to remain unchanged, ensuring the painting effect. It can be used for painting special-shaped plates with limited length and uniform curved surfaces such as wind barriers, and has a faster painting rate. If continuous operation is used to paint longer objects, the driving device as a whole needs to move along the object at a certain rate.

[0029] When another range operation mode is adopted, the device is moved as a whole to the object, and the block between the two groups of positioning rods 14 is painted. During the painting process, the distance between the paint head 6 and the object is controlled in the same way as above. After the painting is completed, the painting process is paused, and the device is moved as a whole to the position where the positioning rod 14 is at the boundary of the painted block, and the block between the two groups of positioning rods 14 at this time is used as a new block for painting again, and the painting operation of the entire object is completed by splicing adjacent blocks. Compared with continuous operation, range operation has a better painting effect due to a longer stay time at one position.

Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the embodiment of the utility model should be included in the protection scope of the utility model.
