Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, and in particular to an automatic positioning spraying device and an automatic spraying system. Background Technology

[0002] In existing technologies, the spraying of complex cross-section profiles mainly employs two methods: robotic spraying and manual spraying. While robotic spraying equipment can achieve automated operation, it suffers from high investment costs, large footprint, high maintenance costs, and requires highly skilled operators. Manual spraying, although lower in cost, suffers from low efficiency, poor film uniformity, and uncontrollable coating quality. The closest existing technology is the F-rail contour spraying device, whose structure includes a contour rail, a spray gun, and a drive mechanism. This device guides the spray gun along the profile surface via the contour rail to achieve the spraying operation. However, this technology suffers from low paint utilization, difficulty in gun adjustment, and difficulty in film thickness control, affecting the spraying effect and operational efficiency. Furthermore, existing spraying devices have poor adaptability to profile cross-sectional shapes, making it difficult to handle complex and varied cross-sectional shapes, thus limiting their application scope.

[0003] Therefore, it is necessary to provide a new automatic positioning spraying device to solve the above-mentioned technical problems. Utility Model Content

[0024] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0025] This utility model proposes an automatic positioning spraying device and an automatic spraying system, aiming to solve the problems of low operating efficiency and poor adaptability of existing spraying equipment.

[0026] See Figure 1The automatic positioning spraying device includes a fixed gantry frame 1, a spraying mechanism 2, a lifting mechanism 3, and an adjusting mechanism 4. The fixed gantry frame 1 forms a working channel 1.1 for the profile to be sprayed to pass through. The spraying mechanism 2 is set in the working channel 1.1 and is used to spray the profile to be sprayed. The lifting mechanism 3 is slidably set on the fixed gantry frame 1 along the extension direction of the working channel 1.1, and is movably connected to the spraying mechanism 2. The lifting mechanism 3 can drive the spraying mechanism 2 to move up and down in the vertical direction. The adjusting mechanism is slidably set on the fixed gantry frame 1 along the extension direction of the working channel 1.1, and is set between the spraying mechanism 2 and the fixed gantry frame 1. The adjusting mechanism 4 can drive the spraying mechanism 2 to rotate and the lifting mechanism 3 and the adjusting mechanism 4 to move relative to the fixed gantry frame 1. In actual operation, the lifting mechanism 3 can adjust the setting height of the spraying mechanism 2, while the adjusting mechanism 4 can adjust the setting angle of the spraying mechanism 2 by rotating the spraying mechanism 2, and move the spraying mechanism 2 and the adjusting mechanism 4 along the direction of the extension of the operation channel 1.1 to adjust the distance between the spraying mechanism 2 and the profile to be sprayed. This enables the rapid adjustment of the spraying distance and spraying angle when spraying different profiles, effectively improving the efficiency of spraying operations and expanding the scope of application.

[0027] The spraying mechanism 2 includes a spraying adjustment frame 2.1, a circular track 2.2, and a spraying trolley 2.3. The center of the spraying adjustment frame 2.1 is movably connected to the lifting mechanism 3. The circular track 2.2 is coaxially arranged with the working channel 1.1 and is set on the spraying adjustment frame 2.1, forming a spraying area for the profile to be sprayed. The spraying trolley 2.3 is slidably set on the circular track 2.2 and can travel along the circular track 2.2, performing spraying operations on the profile in the spraying area. The spraying trolley 2.3 moves along the circular track 2.2, thereby achieving multi-angle spraying of the profile in the spraying area. The lifting mechanism 3 and the adjustment mechanism 4 can flexibly adjust the setting angle and position of the spraying adjustment frame 2.1, thereby enabling fine adjustment of the position of the spraying trolley 2.3 relative to the profile to be sprayed, thus adapting to the spraying operation of profiles with complex curved surfaces. The spraying adjustment frame 2.1 is fixed by a three-point connection and the top adopts a hanging fixing structure, which can quickly realize the left and right movement and angle adjustment of the adjustment and curvature control system, improving the convenience and flexibility of adjustment.

[0028] Specifically, in conjunction with see Figure 2The painting trolley 2.3 includes a body 2.3.1, magnetic wheels 2.3.2, a driving mechanism, a multi-stage adjustment connector 2.3.3, and a spray gun. The body 2.3.1 is slidably mounted on a circular track 2.2 via the magnetic wheels 2.3.2. The output shaft of the driving mechanism is connected to the magnetic wheels 2.3.2. The multi-stage adjustment connector 2.3.3 includes a primary drive valve A1, a primary adjustment arm A2, a secondary drive valve A3, and a secondary adjustment arm A4. The primary drive valve A1 is mounted on the body 2.3.1. The first end of the primary adjustment arm A2 is connected to the output end of the primary drive valve A1, and the primary drive valve A1 can drive the primary adjustment arm A2 to rotate around the primary drive valve A1. The secondary drive valve A3 is mounted on the second end of the primary adjustment arm A2, and the secondary adjustment arm A4 is connected to the output end of the secondary drive valve A3, and the secondary drive valve A3 can drive the secondary adjustment arm A4 to rotate around the secondary drive valve A3. The spray gun is mounted on the secondary adjustment arm A4. The magnetic rollers 2.3.2 are used for fixing and can move along the track corresponding to the elliptical fixing frame, which solves the problem of fixing the position of the spray gun in the spraying process of profiles with different cross-sectional shapes, and improves the adjustment flexibility and applicability and versatility to different profiles; the multi-level adjustment connector 2.3.3 adopts a "two-axis two-arm" structure design, which can help realize the two-dimensional adjustment of the spraying distance and angle of the profile, realize the angle and distance correction when spraying at different positions of the profile, and improve the uniformity of film formation.

[0029] Furthermore, the number of spray painting carriages 2.3 is one or more. Multiple spray painting carriages 2.3 are all set on the circular track 2.2, and the coordinated operation of multiple spray painting carriages 2.3 is conducive to improving the efficiency of spray painting operations.

[0030] Furthermore, the circular track 2.2 is an elliptical track. The elliptical track is better suited for spraying flat profiles, further expanding its applicability and reducing space requirements. In this embodiment, the addition of multiple elliptical tracks enables the staggered arrangement of the spray gun adjustment magnetic carriage and flexible adjustment of the spraying distance and angle. Simultaneously, it avoids paint mist interference during the spraying process of multiple coplanar spray guns, improving spraying quality and spray gun adjustment accuracy.

[0031] In this embodiment, see Figure 3The lifting mechanism 3 includes a telescopic drive component 3.1, a moving wheel 3.2, and a spherical hinge component 3.3. The first end of the telescopic drive component 3.1 is slidably mounted on the fixed gantry frame 1 via the moving wheel 3.2, and the second end of the telescopic drive component 3.1 is movably connected to the spraying adjustment frame 2.1 via the spherical hinge component 3.3. When the adjustment mechanism 4 drives the spraying adjustment frame 2.1 to rotate and move, the lifting mechanism 3 can adapt to the rotation of the spraying adjustment frame 2.1 via the spherical hinge component 3.3 and the movement of the spraying adjustment frame 2.1 via the moving wheel 3.2, thereby ensuring normal spraying operations. In this embodiment, the spraying adjustment frame 2.1 is provided with a base plate 3.6 and a clamping plate 3.5. The base plate 3.6 is provided with a movable groove that matches the spherical hinge component. The spherical support component rolls in contact with the movable groove. The clamping plate 3.5 confines the spherical hinge component 3.3 within the movable groove and is connected to the base plate 3.6 by bolts to realize the movable connection between the telescopic drive component 3.1 and the spraying adjustment frame 2.1. The device employs a wheeled structure connected to a track, with a spherical hinge at the bottom. The moving wheel 3.2 is hinged to the telescopic drive component 3.1 via a pin 3.4, allowing for vertical movement. The lifting mechanism 3 reduces lateral movement resistance by using rolling movement instead of sliding movement. Furthermore, the spherical hinge design at the bottom enables flexible rotation and adjustment of the device.

[0032] See Figure 4 The adjustment mechanism 4 includes two adjustment components 4.1 respectively located on both sides of the spraying adjustment frame 2.1 along the extension direction of the working channel 1.1. The two adjustment components 4.1 are centrally symmetrically arranged. Each adjustment component 4.1 includes a movable base 4.1.1 and an adjustment drive component 4.1.2. The movable wheel 3.2 is detachably and slidably mounted on the fixed gantry frame 1 along the extension direction of the working channel 1.1. The adjustment drive component 4.1.2 is hinged between the spraying adjustment frame 2.1 and the movable base 4.1.1. The adjustment mechanism 4 is used to ensure that the spraying distance between the profile and the spraying material remains constant during the spraying process, and to adjust it to suit the spraying of profiles with different curvatures. The movable base 4.1.1 is provided with a hinge seat 4.1.3 for the adjustment drive component 4.1.2 to hinge onto. The two ends of the adjusting drive component 4.1.2 are respectively hinged to the hinge seat 4.1.3 and the mounting seat 1.4 on the fixed gantry frame 1 via connecting shaft 4.1.4. The synchronous extension and retraction of the two adjusting components 4.1 can drive the spraying adjusting frame 2.1 to rotate; when one adjusting component 4.1 extends and the other adjusting component 4.1 retracts, the spraying adjusting frame 2.1 can be moved along the fixed gantry frame 1 via the lifting mechanism 3, thus realizing the flexible adjustment of the spraying adjusting frame 2.1, which is beneficial for adapting to the spraying operations of different types and curvature profiles. The non-linear staggered arrangement of the two adjusting components 4.1 realizes the curvature fine adjustment of the non-linear profile spraying process by the ring track 2.2, avoiding the need to add a swing cylinder to achieve curvature adjustment, thus simplifying the structure.

[0033] See Figure 5 The fixed gantry frame 1 is also equipped with two height adjustment plates 1.2 corresponding to the adjustment component 4.1. The height adjustment plates 1.2 are detachably connected to the movable seat. The fixed gantry frame 1 is also equipped with left and right moving rails 1.3, which are set in the center of the fixed gantry frame 1 by bolts or welding, for the sliding setting of the lifting mechanism 3. The fixed gantry frame 1 reduces the space occupied in the profile spraying process, and by adopting a split layout design of front and rear transmission mechanisms, it realizes the spraying operation of various profiles without dead angles, while avoiding the deformation risk of traditional profile hanging spraying process. The height adjustment plate 1.2 has an adjustment groove 1.2.1 set in the vertical direction. The movable seat 4.1.1 is slidably set in the adjustment groove 1.2.1 by fasteners, so as to realize the quick adjustment of the height of the movable seat 4.1.1.

[0034] The automatic positioning spraying device also includes a control module, distance sensors 5, a hydraulic pump station 9, and control pipelines 6. The control module is electrically connected to the distance sensors 5 and the hydraulic pump station 9. The distance sensors 5 are located on the side of the circular track 2.2 facing the spraying area and are used to detect the distance between the surface of the profile to be sprayed and the circular track 2.2. The hydraulic pump station 9 controls the telescopic drive component 3.1 and the adjustment drive component 4.1.2 through the control pipelines 6. In this embodiment, there are 6 distance sensors 5, which are evenly arranged on the circular track 2.2. This improves the distance monitoring accuracy and enables real-time monitoring of the distance between the spraying adjustment frame 2.1 and the profile during the profile spraying process. Furthermore, the spraying positioning of the profile structural component can be achieved by setting only a fixed spraying distance parameter.

[0035] See also Figure 6This embodiment also provides an automatic spraying system, including an input device 7, an output device 8, and the automatic positioning spraying device described above. The input device 7 and the output device 8 are respectively located at both ends of the working channel 1.1. The input device 7 includes a bracket 7.1, rollers 7.2, a conveying drive component 7.3, a drive wheel 7.4, a driving wheel 7.5, and a transmission component 7.6. The bracket 7.1 is provided with a plurality of rollers 7.2 spaced apart along the extension direction of the working channel. The rollers 7.2 are in rolling contact with the profile to be sprayed. The conveying drive component 7.3 is provided with... The conveying drive 73 is mounted on the bracket 7.1, and its output shaft is connected to the drive wheel 7.4. The drive wheel 7.5 is mounted on the bracket 7.1 and makes rolling contact with the profile to be coated. The transmission component 7.6 is located between the drive wheel 7.4 and the drive wheel 7.5. The conveying drive can drive the drive wheel 7.5 to rotate through the drive wheel 7.4 and the transmission component 7.6, so that the drive wheel 7.5 moves the profile to be coated. The output device 8 has the same structure as the input device 7 and is arranged opposite to the input device 7. The input device 7 and the output device 8 are used for the front and rear transmission of the profile to be coated during the coating process, respectively. This realizes the suspended coating of each side of the profile in a non-suspended state, solves the problem of hanging and transmitting long profiles during coating, and avoids the risk of profile deformation caused by the coating process.

[0036] In this embodiment, at the start of spraying, a straight profile with the same cross-section as the batch of profiles to be sprayed is taken and placed in the center of the input device 7. The conveying drive 7.3 of the input device 7 is activated, and the front transmission drive wheel 7.5 is rotated through the front transmission sprocket (drive wheel 7.4 and transmission component 7.6), causing the profile to be conveyed forward and pass through the spraying mechanism 2. When the profile is conveyed to the output device 8 and contacts the drive wheel 7.5 of the output device 8, the conveying drive 7.3 of the input device 7 is turned off, so that the profile stops at the left-right center position of the spraying mechanism 2. When the profile is not in the left-right center position of the spraying mechanism 2, the two adjusting components 4.1 are driven by the hydraulic pump station 9 to perform left-right extension and retraction movements, so that the profile is placed in the left-right center position in the spraying mechanism 2. After left-right centering, it is checked whether the spraying height of the profile is reasonable and whether it is in the vertical center position. When the profile spraying height is unsuitable or not centered vertically, loosen the connecting bolts of the movable base 4.1.1 used to fix the two adjustment mechanisms 4. Adjust the distance between the annular track 2.2 installed in the distance spraying mechanism 2 and the profile to be sprayed in the spraying area using the lifting mechanism 3. After the vertical adjustment is completed, tighten the connecting bolts to bring the profile to a suitable spraying height. After the profile position is fixed, measure the vertical, horizontal, and vertical distance parameters between the profile and the annular track 2.2 using four distance sensors 5 installed in the annular track 2.2, and record these distance parameters. Then, the position of the spraying carriage 2.3 is adjusted by motor drive or manually to achieve the best spraying effect on the profile. The adjustment process mainly involves pushing the carriage body 2.3.1 to move its magnetic rollers 2.3.2 along the elliptical track of the circular track 2.2 to initially adjust the spraying angle and distance. Then, by rotating the primary drive valve A1 and the secondary drive valve A3, the primary adjustment arm A2 and the secondary adjustment arm A4 are made to swing to obtain the angle suitable for spraying the profile. After the four spraying carriages 2.3 are adjusted, the secondary adjustment arm A4 fixes the spray gun to the spraying carriage 2.3 through the spray gun fixing seat A5. After the position of the spray gun and the profile is adjusted, the conveying drive component 7.3 of the input device 7 and the output device 8 is started simultaneously, driving the corresponding drive wheel 7.5 to rotate, and the profile begins to be transported. During the transport process, the spray gun is sprayed synchronously to complete the angle adjustment verification before batch spraying. After the profile has completed the test spraying, the coating quality such as film thickness and uniformity is inspected. After repeated tests are conducted to verify until the best spraying quality is obtained, the spray gun is permanently fixed.

[0037] After the optimal spraying angle is fixed, batch spraying can begin. Before spraying, the distance sensor 5 and the profile's left and right distance sensing parameters must be set according to the verification parameters. During spraying, the input device 7 and output device 8's conveying drive 7.3, driving the corresponding drive wheel 7.5 to rotate, causes the profile to move forward. When spraying a straight profile, if the profile's placement and transmission process are always parallel to the spraying adjustment frame 2.1 and centered on the left and right sides of the circular track 2.2, no action is required to complete the profile spraying. When the profile is parallel to the spraying adjustment frame 2.1 but not centered on the left and right sides of the circular track 2.2, if... Figure 1 and Figure 3 As shown, distance sensor 5 first detects that the left-right distance of the profile is inconsistent with the original set distance. When this inconsistency exists, hydraulic pump station 9 starts working, controlling the adjustment drive components 4.1.2 of the two adjustment mechanisms 4 to perform synchronous translational movement through control pipeline 6. This movement drives the spraying adjustment frame 2.1, spraying mechanism 2, and adjustment mechanism 4 to move as a whole, ensuring that the distance between the profile and the circular track 2.2 remains constant. This ensures a constant angle between the spray gun and the profile, guaranteeing coating quality. During this adjustment process, the main movements are the extension and retraction of the adjustment drive components 4.1.2 of the two adjustment mechanisms 4 and the left-right movement of the lifting mechanism 3 along the left-right moving track 1.3. When the profile is not parallel to the spraying adjustment frame 2.1 and is not centered on the left and right sides of the circular track 2.2, the distance sensor 5 first senses that the left and right distance of the profile is inconsistent with the original set distance. When there is an inconsistency in the left and right distance and missing vertical sensing data, the hydraulic pump station 9 starts to work. Through the control pipeline 6, it controls the adjustment drive components 4.1.2 of the two adjustment mechanisms 4 to first perform synchronous translational movement and then perform opposing movement to make the profile parallel to the circular track 2.2 and the distance consistent with the set value. In this adjustment process, the main components are the telescopic movement of the adjustment drive components 4.1.2 of the two adjustment mechanisms 4 and the rotational movement caused by the movement of the object, the left and right movement of the lifting mechanism 3 along the left and right moving track 1.3, and the rotational movement of the telescopic drive component 3.1 at the connection position with the spraying adjustment frame 2.1.

[0038] When spraying curved profiles with the same cross-section, the distance parameters obtained by the distance sensors 5 installed before and after the circular track 2.2 are compared with the original set distance. When the sensing distance at the front of the circular track 2.2 is inconsistent with the set distance, the hydraulic pump station 9 starts working. Through the control pipeline 6, it controls the adjustment drive components 4.1.2 of the two adjustment mechanisms 4 to perform synchronous translational movement so that the sensing distance is consistent with the set distance. When there is a difference in the sensing distance between the front and rear of the circular track 2.2, the hydraulic pump station 9 starts working. Through the control pipeline 6, it controls the adjustment drive components 4.1.2 of the two adjustment mechanisms 4 to first perform synchronous translational movement and then counter-movement to make the profile parallel to the circular track 2.2 and the distance consistent with the set value. In this adjustment process, the main components are the telescopic movement of the adjustment drive components 4.1.2 of the two adjustment mechanisms 4 and the rotational movement caused by the movement of the object, the left and right movement of the lifting mechanism 3 along the left and right moving track 1.3, and the rotational movement of the telescopic drive component 3.1 at the connection position with the spraying adjustment frame 2.1.

[0039] Operation flow of the automatic spraying and positioning device for complex fixed cross-section profiles: 1) Adjust the fixed position and angle of each painting trolley 2.3 on the elliptical track of the circular track 2.2 according to the straight cross-section profile, and obtain the distance parameters of the distance sensor 5.

[0040] 2) Through repeated experiments on the spraying of straight profiles with the same cross section, the optimal spraying distance sensing parameters of the optimal distance sensor 5 and the optimal fixed position of the spraying carriage 2.3 were obtained.

[0041] 3) Set the spray control system parameters to match the obtained optimal parameters and perform batch spray application.

[0042] 4) When spraying straight profiles, if the profile is always placed parallel to the spraying adjustment frame 2.1 and is centered on the left and right sides of the circular track 2.2, the device can complete the profile spraying without any other operation except for the movement of the input device 7 and the output device 8.

[0043] 5) When spraying straight profiles, if the profile is parallel to the spraying adjustment frame 2.1 but not in the center position of the circular track 2.2, the hydraulic pump station 9 starts to work. Through the control pipeline 6, it controls the adjustment drive 4.1.2 of the two adjustment mechanisms 4 to move synchronously, thereby driving the spraying adjustment frame 2.1, the spraying mechanism 2, and the adjustment mechanism 4 to move as a whole during the translation process, so that the distance between the profile and the circular track 2.2 is always a fixed value.

[0044] When the profile is not parallel to the spraying adjustment frame 2.1 and is not centered on the left or right side of the circular track 2.2, or when spraying curved profiles, the distance parameters obtained by the distance sensors 5 installed before and after the circular track 2.2 are compared with the original set distance. When the sensing distance at the front of the circular track 2.2 is inconsistent with the set distance, the hydraulic pump station 9 starts to work. Through the control pipeline 6, it controls the adjustment drive components 4.1.2 of the two adjustment mechanisms 4 to perform synchronous translational movement so that the sensing distance is consistent with the set distance. Then, through the opposing movement, the lifting mechanism 3 rotates, so that the profile is parallel to the circular track 2.2 and the distance is consistent with the set value. This ensures stable spraying operation for profiles with different curvatures.

[0045] Since the automatic spraying system includes the automatic positioning spraying device as described above, the automatic spraying system possesses all the beneficial effects of the automatic positioning spraying device, which will not be elaborated here.
