Description

Technical Field

[0001] The present invention relates to the technical field of shell painting, and in particular to a shell painting device for processing smart door locks. Background Art

[0002] Painting the smart door lock shell is a key process to improve the product appearance and performance. The process covers four major links: pretreatment, primer spraying, topcoat spraying and curing. Among them, the topcoat spraying selects the color and glossiness according to the design requirements, and uses fine spraying technology to achieve a rich color and delicate texture. The protective effect of the paint film on the shell of the smart door lock extends the product life and enhances the corrosion resistance and wear resistance. In order to achieve efficient and precise spraying effects, a reciprocating sprayer is usually used to paint the smart door lock shell.

[0003] A reciprocating paint sprayer uses a motor to drive the nozzle to reciprocate along a specific track. The nozzle sprays paint evenly while moving, and the spraying speed and amount can be precisely adjusted. The reciprocating paint sprayer can adapt to flat or curved workpieces, and achieves full coverage spraying through reciprocating motion and angle adjustment. Existing paint sprayers cannot achieve consistency in spraying on the front and sides of the door lock shell, and the nozzle angle needs to be adjusted before spraying, which affects the painting efficiency.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See also Figures 1-12 The present invention provides a technical solution: a shell painting device for processing an intelligent door lock, comprising a paint spraying machine body 1, a crossbeam 11 is provided inside the paint spraying machine body 1, a sliding beam 12 is slidably connected to the periphery of the crossbeam 11, a sliding frame 13 is slidably connected below the sliding beam 12, and a spray head 14 is provided below the sliding frame 13;

[0035] The door lock housing 2 is located inside the paint spraying machine body 1 and below the spray head 14;

[0036] The rotating mechanism 3 is located between the nozzle 14 and the sliding frame 13. When the sliding frame 13 slides below the sliding beam 12, the rotating mechanism 3 can drive the nozzle 14 to rotate so that the nozzle 14 is always aligned with the door lock housing 2;

[0037] The adjusting mechanism 4 is located inside the nozzle 14 and is capable of adjusting the diameter of the nozzle 14 when the nozzle 14 is rotated by the rotating mechanism 3;

[0038] When the present invention is in use, the rotation mechanism 3 controls the rotation angle of the spray head 14 by the sliding position of the sliding frame 13. When the sliding frame 13 slides, the spray head 14 rotates toward the door lock housing 2. When the sliding frame 13 slides in the opposite direction, the spray head 14 slides in the opposite direction, so that the nozzle of the spray head 14 is always aligned with the door lock housing 2, avoiding manual adjustment of the spray head 14 and improving the consistency of the paint spraying of the spray head 14.

[0039] When the nozzle 14 rotates, the nozzle area of ​​the nozzle 14 is adjusted by the adjustment mechanism 4. When spraying the side of the door lock housing 2, the nozzle area of ​​the nozzle 14 is reduced so that the paint coverage area sprayed by the nozzle 14 is consistent with the side area of ​​the door lock housing 2, thereby reducing paint waste.

[0040] The rotating mechanism 3 includes a conductive sheet 31 fixedly connected to the upper end of the sliding frame 13, a conductive block 32 fixedly connected to the bottom of the sliding beam 12, and a motor 33 provided on the upper end of the nozzle 14. The motor 33 is circuit-connected to the conductive sheet 31 and the conductive block 32 respectively.

[0041] Among them, the lower end of the sliding frame 13 is fixedly connected to the bracket 34, the lower end of the bracket 34 is rotatably connected to the nozzle 14, the outer wall of the bracket 34 is fixedly connected to the support frame 35, the end of the support frame 35 away from the bracket 34 is fixedly connected to the motor 33, and the end of the motor 33 is fixedly connected to the upper end of the nozzle 14.

[0042] When the sliding beam 12 slides outside the cross beam 11, the door lock housing 2 can be sprayed back and forth through the nozzle 14, so that the surface of the door lock housing 2 is evenly sprayed with paint, which can improve the surface smoothness. The uniform paint film thickness can avoid defects such as sagging and orange peel, making the surface of the door lock housing 2 present a mirror or matte texture, meeting the high-end market's demand for visual quality; enhancing color consistency, and avoiding color spots or color differences due to uneven spraying.

[0043] When the sliding frame 13 slides under the sliding beam 12, the position of the nozzle 14 can be adjusted. When the conductive block 32 at the lower end of the sliding beam 12 contacts the conductive sheet 31, since the motor 33 is respectively connected to the conductive sheet 31 and the conductive block 32, the motor 33 is energized and drives the upper end of the nozzle 14 to rotate. At this time, the nozzle 14 and the support frame 35 rotate. The closer the conductive block 32 slides to the end of the conductive sheet 31, the greater the output power of the motor 33. Similarly, the closer the conductive block 32 is to the center of the sliding beam 12, the greater the output power of the motor 33. The smaller the output power of the motor 33, the more the nozzle direction of the nozzle head 14 is always aligned with the door lock housing 2. When the sliding frame 13 slides in the opposite direction, the motor 33 reverses, so that no matter what the sliding direction and position of the nozzle head 14 are, the nozzle position of the nozzle head 14 is always aligned with the door lock housing 2, reducing the idle stroke time of the nozzle head 14, improving the painting efficiency, and also adapting to the painting of complex housing structures. For curved surfaces, deep grooves or special-shaped workpieces, the nozzle of the nozzle head 14 is always aligned with the workpiece to be painted, which can ensure that all surfaces of the workpiece are uniformly covered.

[0044] The adjustment mechanism 4 includes an adjustment box 41 fixedly connected to the outer wall of the nozzle 14, a spring 42 fixedly connected to the inner wall of the adjustment box 41, and an adjustment plate 43 fixedly connected to the end of the spring 42 away from the inner wall of the adjustment box 41. The adjustment plate 43 is located inside the adjustment box 41 and is slidably connected to the adjustment box 41. A limiting member 5 is provided inside the adjustment box 41 to limit the adjustment plate 43.

[0045] Among them, the limiting component 5 includes a limiting rod 51 fixedly connected to the bottom of the adjusting plate 43, a limiting hole 52 is opened at the bottom of the adjusting box 41, the limiting rod 51 is located inside the limiting hole 52 and is slidably connected to the limiting hole 52, and the end of the limiting rod 51 away from the adjusting plate 43 is located outside the adjusting box 41.

[0046] The bottom of the bracket 34 is fixedly connected with an arc-shaped plate 44 , and the arc-shaped plate 44 is located above the adjustment plate 43 .

[0047] When the nozzle 14 rotates, since the arc plate 44 is fixedly connected to the bottom of the bracket 34, the arc plate 44 abuts the adjustment plate 43 and pushes the adjustment plate 43 to slide in the adjustment box 41. At this time, the adjustment plate 43 squeezes the spring 42, and the limiting rod 51 at the bottom of the adjustment plate 43 slides in the limiting hole 52 opened in the adjustment box 41. The vertical sliding of multiple limiting rods 51 can drive the adjustment plate 43 to slide vertically downward, avoiding the downward pressure on one side of the adjustment plate 43, which causes the nozzle of the nozzle 14 to shrink unevenly, and then causes the nozzle 14 to spray the door lock shell 2 unevenly.

[0048] When the adjustment plate 43 slides vertically downward, the adjustment plate 43 can adjust the nozzle area of ​​the nozzle 14 according to the degree to which the arc plate 44 squeezes the adjustment plate 43, and the squeezing degree of the arc plate 44 depends on the rotation angle of the nozzle 14. Therefore, the farther the sliding frame 13 slides, the greater the rotation angle of the nozzle 14, and the greater the force with which the arc plate 44 squeezes the adjustment plate 43, and the longer the sliding distance of the adjustment plate 43 inside the adjustment box 41, which paves the way for adjusting the nozzle area of ​​the nozzle 14.

[0049] A through hole 45 is defined at the bottom of the regulating box 41 , and an regulating slot 46 is defined on the side wall of the nozzle 14 . An regulating rod 47 is fixedly connected to the bottom of the regulating plate 43 . The end of the regulating rod 47 away from the regulating plate 43 is located inside the regulating slot 46 and is slidably connected to the regulating slot 46 .

[0050] The inner wall of the nozzle 14 is fixedly connected to a rotating rod 48 , and the outer periphery of the rotating rod 48 is rotatably connected to a rotating plate 49 . The rotating plate 49 is rotatably connected to the nozzle 14 , and the end of the adjustment rod 47 away from the adjustment plate 43 abuts against the rotating plate 49 .

[0051] When the adjustment plate 43 slides vertically downward, the adjustment rod 47 at the lower end of the adjustment plate 43 slides downward. At this time, the adjustment rod 47 passes through the through hole 45 opened at the bottom of the adjustment box 41. At the same time, the adjustment rod 47 passes through the adjustment slot 46 opened on the side wall of the nozzle 14 and abuts the rotating plate 49, so that the rotating plate 49 rotates around the rotating rod 48. The ends of the rotating plates 49 at both ends are close together to change the size of the nozzle area of ​​the nozzle 14, and the nozzle area of ​​the nozzle 14 is accurately adjusted to meet different painting requirements. Since the front area of ​​the door lock shell 2 is larger than the side area, the nozzle area of ​​the nozzle 14 becomes smaller to adapt to the door lock shell The area of ​​the body 2 enables the nozzle 14 to spray paint on the side of the door lock shell 2, ensuring the accuracy and effectiveness of the paint spraying, and the nozzle area of ​​the nozzle 14 is adjusted as the area of ​​the paint spraying part changes. When spraying a smaller area such as the side of the door lock shell 2, the smaller nozzle area can reduce excessive spraying of paint, effectively avoid paint waste, and reduce production costs. At the same time, precise nozzle area adjustment can make the paint more evenly sprayed on the surface of the door lock shell 2, reducing problems such as uneven paint spraying and sagging caused by excessively large or too small nozzles, thereby improving the paint spraying quality and making the door lock shell 2 more beautiful and durable in appearance.

[0052] A rotating groove 410 is provided inside the rotating plate 49 , and an impact force sensor 411 is provided inside the rotating groove 410 . The impact force sensor 411 is connected to a paint pump circuit that controls the spraying of the nozzle 14 . The paint pump is not shown in the figure.

[0053] When the rotating plate 49 rotates around the rotating rod 48, the nozzle area of ​​the nozzle 14 is changed. At this time, a part of the atomized paint inside the nozzle 14 is sprayed onto the surface of the rotating plate 49. At this time, the paint causes a certain impact force on the rotating plate 49. When the power of the paint pump for painting is inconvenient, reducing the spray diameter of the nozzle 14 will increase the pressure of the paint sprayed by the nozzle 14. By arranging an impact force sensor 411 inside the rotating groove 410, the pressure of the paint sprayed by the nozzle 14 can be monitored in real time. When the pressure increases due to reducing the spray diameter of the nozzle 14, the sensor can promptly feedback the signal to the paint pump, automatically adjust the power of the pump, and ensure that the paint spraying pressure is stable within the optimal range. This dynamic adjustment mechanism effectively avoids the problem of uneven spraying caused by pressure fluctuations, significantly improves the quality of painting, and adjusts the paint pump power in real time. The function of the rate realizes the automatic control of the painting process and reduces the dependence on the operator's skills. This level of automation not only improves production efficiency, but also reduces the spraying quality problems caused by human factors. At the same time, when the power of the paint pump remains unchanged, reducing the diameter of the nozzle 14 will increase the injection pressure, but by adjusting the power of the pump in real time, the pressure can be kept matched with the paint flow rate to avoid excessive atomization or splashing of paint due to excessive pressure. This not only reduces paint waste, but also reduces the environmental burden during the painting process. In addition, the rotating plate 49 is subjected to the impact force of the paint during the painting process. If the pressure is too high, it may cause wear or deformation. By adjusting the power of the paint pump in real time, the impact force can be effectively controlled, reducing damage to key components such as the rotating plate 49, extending the service life of the equipment, and reducing maintenance and replacement costs.

[0054] The working principle and use process of the present invention are as follows: when the sliding frame 13 slides under the sliding beam 12, the position of the nozzle 14 can be adjusted. When the conductive block 32 at the lower end of the sliding beam 12 contacts the conductive sheet 31, since the motor 33 is respectively connected to the conductive sheet 31 and the conductive block 32, the motor 33 is energized at this time, and the motor 33 drives the upper end of the nozzle 14 to rotate. At this time, the nozzle 14 and the support frame 35 rotate. The closer the conductive block 32 slides to the end of the conductive sheet 31, the greater the output power of the motor 33. Conversely, the closer the conductive block 32 is to the center of the sliding beam 12, the greater the output power of the motor 33. The smaller the output power, the nozzle direction of the nozzle head 14 is always aligned with the door lock housing 2. When the sliding bracket 13 slides in the opposite direction, the motor 33 is reversed at this time, so that no matter what the sliding direction and position of the nozzle head 14 are, the nozzle position of the nozzle head 14 is always aligned with the door lock housing 2. When the nozzle head 14 rotates, since the bottom of the bracket 34 is fixedly connected with the curved plate 44, the curved plate 44 abuts the adjustment plate 43 and pushes the adjustment plate 43 to slide in the adjustment box 41. At this time, the adjustment plate 43 squeezes the spring 42, and the limit rod 51 at the bottom of the adjustment plate 43 is located at the limit opened in the adjustment box 41. The adjusting plate 43 slides in the positioning hole 52, and the vertical sliding of the plurality of limit rods 51 can drive the adjusting plate 43 to slide vertically downward. When the adjusting plate 43 slides vertically downward, the adjusting rod 47 at the lower end of the adjusting plate 43 slides downward. At this time, the adjusting rod 47 passes through the through hole 45 opened at the bottom of the adjusting box 41. At the same time, the adjusting rod 47 passes through the adjusting slot 46 opened on the side wall of the nozzle 14 and abuts the rotating plate 49, so that the rotating plate 49 rotates around the rotating rod 48. The ends of the rotating plates 49 at both ends are brought together to change the size of the nozzle area of ​​the nozzle 14. When the rotating plate 49 rotates around the rotating rod 48 , changing the nozzle area of ​​the nozzle 14. At this time, a part of the atomized paint inside the nozzle 14 is sprayed onto the surface of the rotating plate 49. At this time, the paint causes a certain impact force on the rotating plate 49. When the power of the paint pump for spraying paint is inconvenient, reducing the nozzle 14 spray diameter will increase the pressure of the paint sprayed by the nozzle 14. By arranging an impact force sensor 411 inside the rotating groove 410, the pressure of the paint sprayed by the nozzle 14 can be monitored in real time. When the pressure increases due to reducing the nozzle 14 spray diameter, the sensor can timely feedback the signal to the paint pump to automatically adjust the pump power.
