Description

Technical Field

[0001] The invention belongs to the technical field of shell maintenance and painting, and in particular relates to a paint spraying device for maintaining the shell of communication equipment. Background Art

[0002] Communication equipment is widely used in various fields of modern society. The maintenance of its casing is crucial to the normal operation, appearance and service life of the equipment. Painting, as a common and effective maintenance method, plays a key role in protecting the casing of communication equipment from corrosion and improving the appearance quality.

[0003] The shapes of communication equipment shells are diverse, including rectangular and cylindrical shapes, and the sizes and specifications are also different. Traditional painting equipment is difficult to flexibly and accurately adjust to these shells of different shapes and sizes, and thus cannot ensure a full and uniform painting effect. In particular, for special-shaped communication equipment shells, traditional painting equipment has great difficulties in controlling the position and angle of the spray gun, resulting in some areas not being painted properly. A more prominent problem is that when facing the maintenance of communication equipment shells, existing painting equipment can only perform relatively conventional spraying operations on the outer wall, and is unable to spray the inner wall of the shell. The internal structure of communication equipment is complex, and the inner wall of some equipment is irregular in shape. There are also obstructions formed by various mounting components. Existing painting equipment is difficult to penetrate into these small and complex spaces to achieve effective coverage of the inner wall by spraying. This makes the inner wall of the shell extremely susceptible to corrosion due to lack of effective protection during long-term use, thereby affecting the stability and service life of the entire communication equipment. Furthermore, when spraying the edges and corners of the inner wall and top surface of the box, existing spray painting equipment often produces hollow bubbles due to dust and cobwebs inside. When the hollow bubbles burst, they directly damage the paint surface and destroy the continuity of the paint surface, causing a large amount of paint to fall off. Therefore, a solution to the above problem is needed. Summary of the Invention

[0016] The beneficial effects of the present invention compared to the prior art are:

[0017] 1. The present invention can accurately adjust the height of the communication equipment casing through the cooperation of the fourth motor and the lifting screw, thereby improving the adaptation efficiency to casings of different heights, and thus realizing the function of adapting to the height differences of various types of communication equipment casings. Then, through the cooperation of the second motor and the rotating ring, the second motor drives the rotating ring to rotate, which is convenient for flexible adjustment of the angle of the casing, and improves the convenience of adjusting the angle of casings of different shapes, thereby realizing the function of providing multi-angle preparation for precise painting.

[0018] 2. The present invention cooperates with the third motor and the flip ring, and the third motor controls the flip ring to flip, so as to adjust the communication equipment casing that initially enters with the inner wall facing outward to have the outer wall facing outward, thereby improving the conversion efficiency of different painting stages, and thus realizing the function of comprehensive painting preparation of the outer wall of the communication equipment casing. Combined with the cooperation of the first electric push rod and the arc-shaped clamping plate, the first electric push rod drives the arc-shaped clamping plate to move, which is convenient for firmly clamping communication equipment casings of different shapes and sizes, and improves the clamping stability of casings of different specifications, thereby realizing the function of reliable positioning of various types of communication equipment casings. Through the cooperation of the boss on the conveyor belt and the outer wall of the communication equipment casing, the boss reduces the contact area with the outer wall of the communication equipment casing, which is convenient for reducing the risk of friction damage to the paint surface of the sprayed outer wall during the transmission process, and improves the protection effect of the paint surface of the sprayed outer wall.

[0019] 3. The present invention facilitates fine adjustment of the angle of the spray gun through the cooperation of the seventh motor with the worm gear and the worm, thereby improving the control accuracy of the paint spraying angle on the surface of the complex-shaped communication equipment casing, and thus can realize the function of adapting to the angle of the casing surface of different shapes to spray paint. The contraction of the second electric push rod and the cooperation with the first connecting plate and the second connecting plate facilitate precise fine-tuning of the position of the spray gun, thereby improving the accuracy of the spray gun position adjustment in narrow and complex areas, and thus can realize the function of precise paint spraying in narrow and complex areas inside the communication equipment casing. Through the cooperation of the ninth motor and the spray gun, the ninth motor drives the spray gun to rotate, which facilitates flexible adjustment of the angle and range of the paint spraying, improves the coverage effect of the paint spraying, and thus can realize the function of uniformly spraying paint on the communication equipment casing in all directions. Ultimately, it solves the problem that traditional equipment is difficult to flexibly and accurately adjust to the communication equipment casing of different shapes and sizes, and cannot effectively spray paint the inner and outer walls in sequence, especially the problem that the paint effect is poor on special-shaped casings and complex areas on the inner wall, and improves the integrity and uniformity of the paint spraying effect.

[0020] 4. The present invention cooperates with the tenth motor, the turntable, and the dust removal air pipe. The tenth motor drives the turntable to rotate, driving the dust removal air pipe to rotate around the spray gun, making it easy to use high-speed airflow to comprehensively clean dust, spider webs and other impurities at the corners of the top surface of the inner wall of the communication equipment housing, thereby improving the comprehensiveness of the inner wall cleaning and achieving the function of cleaning the surface. Then, through the cooperation of the third electric push rod, the cleaning air pipe, and the electronically controlled three-way valve, the high-pressure airflow can be concentrated and efficiently flushed at the spray gun muzzle. This cooperation can timely and effectively remove the paint liquid attached to the spray gun muzzle, ensuring that the spray gun always maintains a good working condition, effectively improving the stability of paint atomization and spraying during the painting process, greatly reducing paint surface defects caused by paint liquid accumulation at the spray gun muzzle, and ensuring the uniformity and aesthetics of the paint surface; ultimately solving the problem of nozzle blockage and the resulting paint surface defects of existing equipment, and solving the problem of paint surface damage caused by hollowing, bubbling and breaking due to impurities at the corner of the upper inner wall of the box.

The small gear is coaxially fixedly connected to the tenth motor 47 installed on one side of the top surface of the mounting plate, and the other side of the top surface of the mounting plate is connected to a first The air pipe 48 is connected to and fixedly connected to one side of the turntable 46 with a dust-removing air pipe 49, and the bottom end of the dust-removing air pipe 49 is in the shape of a cone; a third electric push rod 50 is hinged at the upper end of the dust-removing air pipe 49 on the opposite surface of the spray gun 43, and a cleaning air pipe 51 is hinged on the output shaft of the third electric push rod 50, one end of the cleaning air pipe 51 is connected to the dust-removing air pipe 49, and the cleaning air pipe 51 is provided with a sleeve at the connection between the outer wall of the dust-removing air pipe 49, and the sleeve is hinged to the dust-removing air pipe 49, and a storage groove for accommodating the cleaning air pipe 51 and the third electric push rod 50 is provided on the dust-removing air pipe 49. A three-way valve 52 is provided at the clean air pipe 51 on the outer wall of the dust-removing air pipe 49, and one end of the first air pipe 48 is connected to a hair dryer 53 installed on one side of the screw box.

[0043] The third electric push rod 50 adopts a small electric push rod with precise telescopic control ability, which can push the cleaning air pipe 51 out of the storage slot. The cleaning air pipe 51 is made of flexible stainless steel, has good flexibility, and can flexibly adjust the angle. When it is necessary to clean the residual paint liquid at the nozzle of the spray gun 43, the compressed air generated by the blower 53 flows into the dust removal air pipe 49 through the first air pipe 48, and then switches the air flow direction through the electric three-way valve 52 to guide the compressed air to the cleaning air pipe 51 to spray and clean the nozzle of the spray gun 43, effectively solving the problem of nozzle clogging of the spray gun 43 after long-term use of the existing equipment. Problem: After cleaning is completed, the electric three-way valve 52 automatically closes the air inlet of the cleaning air pipe 51 to avoid wasting compressed air. The storage slot is cleverly designed so that the cleaning components can be completely embedded in the dust removal air pipe 49 when not in use, avoiding interference with normal spraying operations, ensuring the orderly operation of various functions of the equipment, and comprehensively improving the spraying quality and efficiency. The hair dryer 53 selected here is the GF-120 centrifugal fan, which can provide a stable and sufficient air source to meet the equipment cleaning and dust removal needs; the electric three-way valve 52 model is 2W-200-25, and its automatic control performance is reliable, and it can accurately realize the switching of airflow direction. The selected tenth motor 47 is a micro servo motor with high-precision speed control characteristics. It can stably drive the turntable 46 to rotate, and drive the dust removal air pipe 49 to rotate around the spray gun 43 at a uniform speed. The dust removal air pipe 49 is made of lightweight aluminum alloy, and its bottom end is aerodynamically optimized into a cone shape. Combined with the compressed air introduced by the first air pipe 48, it can efficiently spray high-speed spiral airflow, effectively removing dust, cobwebs and other impurities from the edges and corners of the top surface of the inner wall of the communication equipment casing, and effectively solve the problem of hollowing and bubbling caused by incomplete cleaning before spraying. The mounting plate and turntable 46 are made of engineering plastic (ABS), which takes into account both strength and corrosion resistance, extends the service life of components, and ensures that the paint surface has good adhesion and integrity.

[0044] In this embodiment, a method for using a paint spraying device for maintaining a communication device housing includes the following steps:

[0045] Step one: first place the communication equipment casing on the conveyor belt 4, and rely on the multiple bosses 11 evenly distributed on the conveyor belt 4 to reduce the contact area with the communication equipment casing, so as to avoid damage to the painted outer wall during the transmission process. Start the first motor 5 to drive the conveyor belt 4 to smoothly send the communication equipment casing into the painting area in the cabinet 1. At the same time, turn on the first exhaust fan 12 and the second exhaust fan 14 in the exhaust assembly. They cooperate with the exhaust hood 13 to quickly and effectively exhaust the original air in the painting area, create a good air circulation environment, and create a healthy and environmentally friendly space for subsequent painting operations.

[0046] In step 2, the conveyor belt 4 transports the opening of the communication equipment shell upward to the first group of paint spraying components; and makes the first group of paint spraying components descend to the inside of the communication equipment shell. Before painting, the inner wall of the communication equipment shell is cleaned first; the tenth motor 47 is started, driving the turntable 46 to rotate, so that the dust removal air pipe 49 rotates around the spray gun 43; the first air pipe 48 introduces the compressed air generated by the blower 53, and the compressed air is ejected into a high-speed airflow through the cone-shaped dust removal air pipe 49 to comprehensively clean the dust, cobwebs and other impurities on the top corners of the inner wall of the communication equipment shell; if some narrow gaps and special areas need to be deeply cleaned, the third electric push rod 50 pushes the cleaning air pipe 51 out of the storage slot, and the electric-controlled three-way valve 52 switches the airflow direction, directing the compressed air to the cleaning air pipe 51, and directionally sweeping these areas to ensure that there is no impurity residue on the inner wall, providing a good foundation for subsequent painting; after cleaning is completed, the inner wall painting operation begins; the paint spraying component is started, and the fifth motor drives the second screw rod 26 to rotate, prompting the first slider to move along the screw rod The outer sleeve 27 and the inner sleeve 28 are moved to precisely adjust the horizontal position of the outer sleeve 27 and the inner sleeve 28 so that the spray gun 43 is accurately aligned with the inner wall of the shell; then the sixth motor drives the second driving gear 30 to rotate, which engages with the rack 29 on the outer wall of the inner sleeve 28, driving the inner sleeve 28 to move up and down, and precisely adjusting the vertical height of the spray gun 43; then, the seventh motor drives the worm 33 to rotate, so that the worm wheel 32 and the second rotating shaft 31 rotate, and finely adjust the angle of the spray gun 43 to adapt to the complex shape of the inner wall; the self-locking motor 35 controls the articulated seat 3 4 rotates to further adjust the tilt angle of the spray gun 43; the second electric push rod 36 contracts, pushing the first connecting plate and the second connecting plate 37 to move, and accurately fine-tuning the position of the spray gun 43; the eighth motor 38 engages with the second driven gear 40 through the third driving gear 39 to adjust the direction of the third connecting plate 41 and the spray gun 43; finally, the ninth motor 42 drives the spray gun 43 to rotate, and the paint is transported from the paint tank 15 to the spray gun 43 through the telescopic hose, and the inner wall is evenly sprayed with paint to ensure that all parts of the inner wall are evenly covered with paint.

[0047] Step three, after the inner wall painting operation is completed, the conveyor belt 4 continues to operate, and transports the communication equipment casing forward to the clamping and flipping assembly, and starts the fourth motor in the clamping and flipping assembly. The fourth motor drives the lifting screw 16 to rotate, driving the lifting platform 18 and related connecting components to accurately lift and lower, and adjust the communication equipment casing to a suitable height. Then, the second motor 23 runs, driving the rotating ring 20 to rotate, and flexibly adjusting the casing angle. Subsequently, the third motor comes into play, controlling the flip ring 24 to flip, and converting the communication equipment casing from the inner wall facing outward to the outer wall facing outward. At this time, the first electric push rod 25 pushes the arc-shaped clamping plate 45 to move, and uses the anti-slip rubber ridges 44 on the surface of the arc-shaped clamping plate 45 to firmly clamp the edges of the communication equipment casing, preparing for the outer wall painting operation.

[0048] Step 4: After the communication equipment casing is flipped and adjusted, it continues to be conveyed forward with the conveyor belt 4 to the second set of paint spraying components, and the operation process of the paint spraying components in step 2 is repeated. The fifth motor drives the second screw 26 to rotate again, driving the first slider to move, and accurately adjusts the horizontal position of the outer sleeve 27 and the inner sleeve 28, so that the spray gun 43 is accurately aligned with the outer wall of the communication equipment casing. The sixth motor adjusts the vertical height of the inner sleeve 28 through the engagement of the second driving gear 30 with the rack 29, further accurately positioning the spray gun 43. The seventh motor drives the worm 33 to rotate, driving the worm gear 32 and the second rotating shaft 31 to rotate, and finely adjusts the angle of the spray gun 43 to fit the shape of the outer wall, and then controls the articulated seat through the self-locking motor 35. 34 rotates to accurately adjust the inclination angle of the spray gun 43; the second electric push rod 36 contracts to push the first connecting plate and the second connecting plate 37 to move, and accurately fine-tune the position of the spray gun 43. The eighth motor 38 adjusts the direction of the third connecting plate 41 and the spray gun 43 through the engagement of the third driving gear 39 and the second driven gear 40. Finally, the ninth motor 42 drives the spray gun 43 to rotate, and the outer wall of the communication equipment casing is sprayed with paint to achieve uniform spraying of the outer wall; similarly, at this stage, after the spray gun 43 has worked for a period of time, the cleaning device will be started in accordance with the above step 2 to clean the residual paint liquid at the nozzle of the spray gun 43 to ensure that the spray gun 43 always maintains a good painting state and guarantees the quality of the outer wall painting.

[0049] Step 5. After the outer wall painting operation is completed, the conveyor belt 4 sends the communication equipment casing out of the cabinet 1 through the side without the rubber curtain 7. At the same time, turn off the motors, electric push rods, exhaust components and other equipment, open the hinged cabinet door 9 on the outer wall of the cabinet 1, and pull out the collection box 8 inserted in the collection trough. The paint dripped and collected during the painting process is subsequently processed. The interior of the cabinet 1 can also be inspected and maintained through the inspection glass door 2.
