Technical Field

[0001] This invention relates to the field of spraying equipment technology, specifically to an automatic spraying device and spraying method. Background Technology

[0002] Automatic spraying equipment is a core piece of equipment that replaces manual painting and achieves standardized and efficient surface treatment. It is widely used in automobiles, home appliances, furniture, 3C electronics, aerospace and other fields.

[0003] Patent publication number CN212309939U relates to an automatic spraying device for automatically spraying a conductive coating onto the surface of a developing roller. The automatic spraying device includes a spraying implementation component and a spraying positioning component. The spraying positioning component has a spraying station and a loading / unloading station. The spraying positioning component includes a position exchange component, and a first positioning component and a second positioning component for fixing the developing roller. The position exchange component exchanges the positions of the first positioning component and the second positioning component at the spraying station and the loading / unloading station. The spraying implementation component sprays the developing roller at the spraying station. This automatic spraying device can automatically complete the spraying process of the developing roller, with high production efficiency and reduced labor costs.

[0004] Although the automatic spraying device of this equipment can automatically complete the spraying process of the developing roller, it has high production efficiency and can save labor costs. However, the device is prone to clogging of the spray nozzle during spraying, which reduces the spraying efficiency of the equipment and causes blind spots in the spraying. At the same time, it is cumbersome to repeatedly adjust the data through the control panel during spraying, which can easily cause the equipment clamping to shift. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an automatic spraying device and spraying method, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: an automatic spraying device, including a spraying control console, an electric slide rail fixedly installed on the spraying control console, and a sliding mounting frame for position adjustment slidably installed at the moving end of the electric slide rail, characterized in that the automatic spraying device and spraying method further include a rotary cleaning mechanism installed on the sliding mounting frame and a multi-row fixing mechanism for sprayed parts installed on the spraying control console; The rotary cleaning mechanism includes a spray frame mounted on the sliding mounting bracket for reciprocating spraying, a rotary head mounted on the spray frame, a spray head mounted on the rotary head, an electric gear mounted on the rotary head, a gear ring I mounted on the rotary head, a rotary cylinder mounted on the gear ring I, and a cleaning rod mounted on the rotary cylinder. The electric gear meshes with the gear ring I and is driven by a built-in motor inside the rotary head. The rotary cylinder is rotatably connected to the outer wall of the spray head, and the cleaning rod contacts the spray nozzle of the spray head for rotating and cleaning the spray nozzle of the spray head.

[0007] The multi-row fixing mechanism for the sprayed parts includes a movable slide rail installed on the spraying control console, a movable platform installed on the movable end of the movable slide rail, a multi-row fixing plate installed on the movable platform, a limiting rod installed on the multi-row fixing plate, a cross rod installed on the limiting rod, and a threaded rod installed on the multi-row fixing plate, for fixing the sprayed parts in multiple rows.

[0008] The threaded rod has a threaded groove on its circumference, and the threaded rod is internally threaded to the cross rod. The outer wall of the limiting rod has an arc groove.

[0009] The automatic spraying device also includes an elastic fixing mechanism installed on the cross bar for elastic reinforcement of the sprayed parts; The elastic fixing mechanism includes a sliding column mounted on the cross rod, a ring mounted on the sliding column, a pressure plate mounted on the end of the ring away from the ring, and a spring mounted on the circumferential surface of the sliding column. The ring is in contact with the outer wall of the cross rod, the spring is in contact with the outer wall of the cross rod, and the end of the spring away from the cross rod is in contact with the pressure plate.

[0010] The automatic spraying device also includes a knocking and shaking mechanism installed on the cleaning rod, used to shake off impurities from the spray nozzle of the spray head; The knocking and shaking mechanism includes a positioning block mounted on the cleaning rod, a knocking rod mounted inside the positioning block, and an inclined plate mounted on the spray head.

[0011] The striking end of the striking rod contacts the spray head, the outer wall of the inclined plate has an inclined surface, and a torsion spring is provided between the striking rod and the positioning block.

[0012] The automatic spraying device also includes a rotary spraying mechanism installed on the multi-row fixed plate, used for rotary spraying of the multi-row spraying parts; The rotary spraying mechanism includes a toothed ring II mounted on the multi-row fixed discs and a rack mounted on the spraying control console, wherein the toothed ring II meshes with the rack.

[0013] The automatic spraying device also includes an anti-deviation mechanism installed on the cross bar to prevent the sprayed part from shifting when it is fixed. The anti-deviation mechanism includes a connecting plate mounted on the cross bar, a connecting rod mounted on the connecting plate, a spring mounted on the circumferential surface of the connecting rod, a movable housing mounted on the connecting rod, and a circular roller mounted inside the movable housing.

[0014] The second spring contacts the connecting plate, and the circumferential surface of the roller contacts the arc groove of the limiting rod.

[0015] An automated spraying method includes the following steps: Step 1: When spraying the circumferential surface of the can, the produced can needs to be placed into the equipment. At this time, the equipment will be started through the control panel. The control panel will start the electric slide rail. The electric slide rail will drive the sliding mounting bracket to adjust its position through the output end. This will cause the sliding mounting bracket to move the spraying frame to the corresponding position. The spraying frame will drive the rotating head to adjust its position. The rotating head will drive the spraying head to adjust its position. The spraying head will move to the corresponding position to prevent blind spots during spraying. Step 2: When spraying the parts, the internal motor of the rotating head is started. The internal motor drives the electric gear to rotate. The electric gear meshes with the gear ring. The rotation of the electric gear drives the gear ring to rotate through the teeth of the gear ring. The rotation of the electric gear drives the gear ring to rotate through the teeth. The gear ring drives the rotating cylinder to rotate. The rotation of the rotating cylinder drives the cleaning rod to rotate. The cleaning rod cleans the spray nozzle of the spray head. Step 3: Before spraying, start the moving slide rail through the control panel. The moving slide rail will drive the moving table through the output end. The moving table will move the multi-row fixed plate to the front. The multi-row fixed plate will drive the limit rod and threaded rod to the front of the equipment. When it reaches the front of the equipment, the operator will put the part to be sprayed into the corresponding position of the multi-row fixed plate. Step 4: At this point, the operator will manually rotate the threaded rod. The rotation of the threaded rod will cause the threaded groove on the circumferential surface to rotate. The threaded rod will drive the cross rod to move through the threaded groove on the circumferential surface. The movement of the cross rod will move along the direction of the limit rod. The downward movement of the cross rod will fix the part to be painted. After fixing, the moving slide rail will be started through the main control panel. The operation of the moving slide rail will drive the multiple rows of fixed plates to move through the output end. The multiple rows of fixed plates will drive the part to be painted to the corresponding position for painting.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, during spraying, the electric slide rail drives the sliding mounting bracket for adjustment, which in turn drives the rotating head for displacement adjustment. The rotating head moves the spray nozzle to the corresponding position, preventing blind spots during spraying. When spraying the parts, the internal motor of the rotating head drives the cleaning rod to rotate, which cleans the spray nozzle orifice, improving spraying quality and consistency. Real-time cleaning of the spray nozzle prevents paint from drying and clogging, ensuring stable liquid output, reducing downtime for maintenance, and extending nozzle life. Simultaneously, the reciprocating and clogging-clearing operations are linked, improving continuous spraying performance. It improves continuity and production efficiency, reduces scrap rates, and is more suitable for continuous, high-precision automated production. Before spraying, the moving table is moved by the moving slide rail. The moving table moves multiple rows of fixed plates to the front. The threaded rod is rotated manually, and the threaded rod moves the cross rod down to fix the sprayed parts, realizing quick clamping and positioning, improving the versatility of the device. After adjustment, it can be reliably locked to ensure that it does not shake or shift during spraying or operation, improves the accuracy of the spraying trajectory and product consistency, and at the same time reduces the replacement of special fixtures, shortens the debugging time, and enhances the adaptability of the device to multi-specification production.

[0017] 2. In this invention, after the part to be coated is fixed, the cross bar drives the sliding column to move downward, and the sliding column drives the pressure plate for elastic reinforcement. This can adapt to differences in workpiece size and thickness, resulting in a tighter fit and less loosening. During operation, it buffers vibration and impact, keeping the coating or movement stable, improving the quality of the finished product, and reducing rigid collisions and wear. During the coating process, the rotation of the cleaning rod will drive the positioning block to rotate, which in turn will drive the striking rod to rotate along the trajectory of the inclined plate. The rotating striking rod will strike the spray nozzle of the spray head through the striking end, thereby shaking off impurities in the spray nozzle. The striking vibration can quickly shake off the dried paint and impurities in the spray nozzle, keeping the nozzle unobstructed and avoiding blockages that could lead to interrupted spraying, missed spraying, or uneven coating. No manual disassembly and cleaning is required, reducing downtime for maintenance and improving the quality of the coated surface and the yield rate of the finished product.

[0018] 3. In this invention, during spraying, multiple rows of fixed discs drive the toothed ring two to reset and move. The toothed ring two meshes with the rack, and the toothed ring two moves along the teeth of the rack, driving the multiple rows of fixed discs to rotate. The rotation of the multiple rows of fixed discs drives the tank to rotate and spray, thereby increasing the spraying area, ensuring that the paint in the tank is always evenly mixed, avoiding the sedimentation and stratification of pigments and fillers, ensuring consistent spraying concentration, and stable coating quality. Combined with the reciprocating spraying motion, the material output is more uniform and stable. During fixing, the cross rod drives the connecting plate to move, the connecting plate drives the connecting rod to move downward, the connecting rod drives the moving shell to move downward, and the moving shell drives the circular roller to move downward. The circular roller, in conjunction with the arc groove damping on the limit rod, provides stable resistance, making the reciprocating spraying motion more uniform and gentle, avoiding start-stop impact and vibration, ensuring uniform spraying trajectory, suppressing mechanism shaking and resonance, improving spraying accuracy, reducing uneven coating thickness, and improving operational reliability and continuous working stability.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1:

[0022] Please see Figures 1-4 An embodiment of the present invention is: an automatic spraying device, including a spraying control console 1, an electric slide rail 2 fixedly installed on the spraying control console 1, and a sliding mounting frame 3 for position adjustment slidably installed on the moving end of the electric slide rail 2. The automatic spraying device and spraying method further include a rotary cleaning mechanism installed on the sliding mounting frame 3 and a multi-row fixing mechanism for sprayed parts installed on the spraying control console 1. The rotary cleaning mechanism includes a spray frame 4 mounted on a sliding mounting frame 3 for reciprocating spraying, a rotary head 5 mounted on the spray frame 4, a spray head 10 mounted on the rotary head 5, an electric gear 6 mounted on the rotary head 5, a gear ring 7 mounted on the rotary head 5, a rotary cylinder 8 mounted on the gear ring 7, and a cleaning rod 9 mounted on the rotary cylinder 8. The electric gear 6 meshes with the gear ring 7 and is driven by a built-in motor inside the rotary head 5. The rotary cylinder 8 is rotatably connected to the outer wall of the spray head 10, and the cleaning rod 9 contacts the spray nozzle of the spray head 10 for rotary cleaning of the spray nozzle of the spray head 10.

[0023] The multi-row fixing mechanism for sprayed parts includes a movable slide rail 11 installed on the spraying control console 1, a movable table 12 installed at the moving end of the movable slide rail 11, a multi-row fixing plate 13 installed on the movable table 12, a limiting rod 16 installed on the multi-row fixing plate 13, a cross rod 15 installed on the limiting rod 16, and a threaded rod 14 installed on the multi-row fixing plate 13, for fixing the sprayed parts in multiple rows.

[0024] The threaded rod 14 has a threaded groove on its circumferential surface. The threaded rod 14 is internally threaded to the cross rod 15. The limit rod 16 has an arc groove on its outer wall.

[0025] In this embodiment, during operation: When spraying the circumferential surface of the can, the produced can needs to be placed into the equipment. The equipment is then started via the control console. The control console activates the electric slide rail 2, which in turn drives the sliding mounting bracket 3 to adjust its position. This causes the sliding mounting bracket 3 to move the spraying frame 4 to the corresponding position. The spraying frame 4 then drives the rotating head 5 to adjust its position, which in turn drives the spraying head 10 to adjust its position, preventing blind spots during spraying. When spraying the part, the internal motor of the rotating head 5 is activated. The internal motor drives the electric gear 6 to rotate, and the electric gear 6 meshes with the gear ring 7. The electric gear 6 rotates along the teeth of the gear ring 7, which in turn drives the gear ring 7 to rotate. The gear ring 7 then drives the rotating cylinder 8 to rotate, which in turn drives the cleaning rod 9 to rotate. The cleaning rod 9 cleans the spray nozzle of the spray head 10. This automatic spraying device, which can reciprocate and adjust the spraying and simultaneously clean the spray nozzle, can ensure uniform coating thickness, no missed coating or material accumulation, and improve spraying quality and consistency. Real-time cleaning of the spray nozzle can prevent paint from drying and clogging, ensure stable liquid output, reduce downtime maintenance, and extend nozzle life. At the same time, the reciprocating and clogging-clearing linkage improves spraying continuity and production efficiency, reduces scrap rate, and is more suitable for continuous, high-precision automated production. Before spraying, the movable slide rail 11 is activated via the control console. The movable slide rail 11, through its output end, moves the movable table 12. The movable table 12 moves the multi-row fixed discs 13 to the front, which in turn moves the limit rod 16 and threaded rod 14 to the front of the equipment. Once at the front, the operator places the part to be sprayed into the corresponding position on the multi-row fixed discs 13. At this point, the operator manually rotates the threaded rod 14. This rotation rotates the threaded groove on the circumferential surface, which in turn moves the cross rod 15 along the threaded groove. The position lever 16 is displaced in the direction of the cross lever 15, which moves down to fix the part to be painted. After fixing, the moving slide rail 11 is started through the main control panel. The moving slide rail 11 will drive the multi-row fixed plate 13 to move through the output end. The multi-row fixed plate 13 will drive the part to be painted to the corresponding position for painting. It can adapt to workpieces or parts of different sizes and thicknesses, realize quick clamping and positioning, improve the versatility of the device, and reliably lock after adjustment. It can ensure that there is no shaking or displacement during the painting or working process, improve the accuracy of the painting trajectory and the consistency of the product, reduce the replacement of special fixtures, shorten the debugging time, and enhance the adaptability of the device to multi-specification production. Example 2:

[0026] Please see Figures 5-6Based on the above embodiments, in another embodiment of the present invention, the automatic spraying device further includes an elastic fixing mechanism 17 installed on the cross bar 15 for elastically reinforcing the sprayed parts; The elastic fixing mechanism 17 includes a sliding column 171 mounted on the cross bar 15, a ring 172 mounted on the sliding column 171, a pressure plate 173 mounted on the end of the ring 172 away from the ring 172, and a spring 174 mounted on the circumferential surface of the sliding column 171. The ring 172 is in contact with the outer wall of the cross bar 15, the spring 174 is in contact with the outer wall of the cross bar 15, and the end of the spring 174 away from the cross bar 15 is in contact with the pressure plate 173.

[0027] The automatic spraying device also includes a knocking and shaking mechanism mounted on the cleaning rod 9, which is used to shake off impurities from the spray nozzle of the spray head 10; The knocking and shaking mechanism includes a positioning block 175 mounted on the cleaning rod 9, a knocking rod 176 mounted inside the positioning block 175, and an inclined plate 177 mounted on the spray head 10.

[0028] The striking end of the striking rod 176 contacts the spray head 10, the outer wall of the inclined plate 177 is provided with an inclined surface, and a torsion spring is provided between the striking rod 176 and the positioning block 175.

[0029] In this embodiment, when the part to be painted is fixed, the rotation of the threaded rod 14 will drive the cross rod 15 to move along the limiting rod 16 through the threaded groove. The downward movement of the cross rod 15 will drive the sliding column 171 to move downward. The sliding column 171 will drive the pressure plate 173 to move. The pressure plate 173 will move downward and contact the top of the part to be painted. The contact of the pressure plate 173 will drive the spring 174 to compress. At the same time as the spring 174 is compressed, the sliding column 171 will drive the ring 172 to move upward. The pressure plate 173, together with the spring 174, provides elastic reinforcement to the part to be painted. It can adapt to the differences in workpiece size and thickness, fit more tightly, and is not easy to loosen. During operation, it buffers vibration and impact, keeps the painting or movement stable, improves the quality of finished products, reduces rigid collisions and wear, protects parts, and extends service life. During the spraying process, the rotation of the electric gear 6 drives the cleaning rod 9 to clean the spray nozzle of the spray head 10. During cleaning, the rotation of the cleaning rod 9 drives the positioning block 175 to rotate, which in turn drives the striking rod 176 to rotate along the trajectory of the inclined plate 177. The rotating striking rod 176 contacts the inclined surface of the inclined plate 177 through its striking end. At this time, the striking rod 176 rotates along with the hinge point of the positioning block 175. The rotation of the striking rod 176 drives the internal torsion spring to rotate. When the striking rod 176 leaves the inclined plate 177... Afterwards, the striking rod 176 will be reset by the torsion spring between it and the positioning block 175. The reset of the striking rod 176 will knock the spray nozzle of the spray head 10 through the striking end, thereby shaking off the impurities in the spray nozzle. The knocking vibration can quickly shake off the dried paint and impurities in the spray nozzle, keep the nozzle unobstructed, avoid blockage that may cause interrupted spraying, missed spraying or uneven spraying, eliminate the need for manual disassembly and cleaning, reduce downtime maintenance time, ensure continuous spraying efficiency, prevent impurities from spraying out with the paint and causing coating defects, and improve the surface quality and finished product qualification rate. Example 3:

[0030] Please see Figures 7-8 Based on the above embodiments, in another embodiment of the present invention, the automatic spraying device further includes a rotary spraying mechanism 18 mounted on a multi-row fixed plate 13 for rotary spraying of multi-row spraying parts. The rotary spraying mechanism 18 includes a gear ring 181 mounted on a multi-row fixed plate 13 and a rack 182 mounted on the spraying control console 1, wherein the gear ring 181 meshes with the rack 182.

[0031] The automatic spraying device also includes an anti-deviation mechanism mounted on the cross bar 15 to prevent the sprayed part from shifting when it is fixed. The anti-deviation mechanism includes a connecting plate 183 mounted on the cross bar 15, a connecting rod 184 mounted on the connecting plate 183, a spring 185 mounted on the circumferential surface of the connecting rod 184, a movable housing 186 mounted on the connecting rod 184, and a roller 187 mounted inside the movable housing 186.

[0032] Spring 185 contacts the connecting plate 183, and the circumferential surface of the roller 187 contacts the arc groove of the limiting rod 16.

[0033] In this embodiment, during spraying, the moving slide rail 11 is activated. The moving slide rail 11 drives the moving platform 12 to reset and move via the moving end. The moving platform 12 drives the multi-row fixed disks 13 to reciprocate. The multi-row fixed disks 13 drive the tank to reciprocate for spraying. At this time, the reciprocating movement of the multi-row fixed disks 13 drives the toothed ring 181 to reset and move. The toothed ring 181 meshes with the rack 182. The reciprocating movement of the toothed ring 181 moves along the teeth of the rack 182. The movement of the toothed ring 181 along the teeth of the rack 182 drives the multi-row fixed disks 13 to rotate. The rotation of the multi-row fixed disks 13 drives the tank to rotate for spraying, thereby increasing the spraying area, ensuring that the paint in the tank is always evenly mixed, avoiding the sedimentation and stratification of pigments and fillers, ensuring consistent spraying concentration, and stable coating quality. Combined with the reciprocating spraying motion, the material output is more uniform and stable, improving the spraying atomization effect, increasing surface smoothness, expanding the applicability of the device, and reducing manual stirring and auxiliary operations. When fixed, the cross bar 15 drives the connecting plate 183 to move. The movement of the connecting plate 183 will drive the connecting rod 184 to move downward. The connecting rod 184 will drive the moving shell 186 to move downward. The moving shell 186 will drive the roller 187 to move downward. The roller 187 moves and slides along the limiting rod 16. When the roller 187 slides along the limiting rod 16, it will drive the moving shell 186 to move backward. The moving shell 186 will drive the connecting rod 184 to move backward. The backward movement of the connecting rod 184 will compress the spring. When the roller 187 enters the arc of the limiting rod 16... After the groove, the circular roller 187 will be elastically reset by the spring on the connecting rod 184. The circular roller 187 cooperates with the arc groove damping on the limiting rod 16. At this time, the circular roller 187 and the arc groove on the limiting rod 16 will prevent the cross rod 15 from loosening, provide stable resistance, make the reciprocating spraying motion more uniform and smooth, avoid start-stop impact and vibration, ensure uniform spraying trajectory, suppress mechanism shaking and resonance, improve spraying accuracy, reduce uneven coating thickness, and make the movement stable and controllable. It does not require frequent adjustment and improves the reliability of operation and the stability of continuous operation. Example 4:

[0034] Based on Examples 1, 2, and 3, this example provides an automatic spraying method, which includes the following steps: Step 1: When spraying the circumferential surface of the can, the produced can needs to be placed into the equipment. At this time, the equipment will be started through the control panel. The control panel will start the electric slide rail 2. The operation of the electric slide rail 2 will drive the sliding mounting bracket 3 to adjust its displacement through the output end. This will cause the sliding mounting bracket 3 to move the spraying frame 4 to the corresponding position. The spraying frame 4 will drive the rotating head 5 to adjust its displacement. The rotating head 5 will drive the spraying head 10 to adjust its displacement. The spraying head 10 will move to the corresponding position to prevent blind spots during spraying. Step 2: When spraying the parts, the internal motor of the rotating head 5 is started. The internal motor drives the electric gear 6 to rotate. The electric gear 6 meshes with the gear ring 7. The rotation of the electric gear 6 drives the gear ring 7 to rotate through the teeth. The gear ring 7 drives the rotating cylinder 8 to rotate. The rotation of the rotating cylinder 8 drives the cleaning rod 9 to rotate. The cleaning rod 9 cleans the spray nozzle of the spray head 10. Step 3: Before spraying, start the moving slide rail 11 through the control panel. The moving slide rail 11 will drive the moving table 12 to move through the output end. The moving table 12 will drive the multi-row fixed plate 13 to the front. The multi-row fixed plate 13 will drive the limit rod 16 and the threaded rod 14 to the front of the equipment. When it reaches the front of the equipment, the operator will put the part to be sprayed into the corresponding position of the multi-row fixed plate 13. Step 4: At this time, the operator will manually rotate the threaded rod 14. The rotation of the threaded rod 14 will drive the threaded groove on the circumferential surface to rotate. The threaded rod 14 will drive the cross rod 15 to move through the threaded groove on the circumferential surface. The cross rod 15 will move along the direction of the limit rod 16. The downward movement of the cross rod 15 will fix the part to be painted. After the fixation is completed, the moving slide rail 11 will be started through the main control panel. The operation of the moving slide rail 11 will drive the multi-row fixed plate 13 to move through the output end. The multi-row fixed plate 13 will drive the part to be painted to the corresponding position for painting.
