Description

Technical Field

[0001] This invention relates to the field of coating equipment technology, specifically a rotating system for a vertical coating machine for a blower housing. Background Technology

[0002] Currently, the coating process for hair dryer housings mostly employs vertical spray coating equipment for surface treatment. This type of equipment typically consists of a fixed spray coating chamber, a rotating fixture mechanism, and a spray coating nozzle. Its working principle is generally as follows: the hair dryer housing is fixed to the fixture clamp, the fixture is rotated by a motor, and simultaneously, the nozzle sprays coating onto the workpiece surface. However, in practical use, existing vertical coating machines still have significant shortcomings in terms of fixture posture switching, spray coating alignment, and coating uniformity.

[0003] Firstly, regarding the attitude transition between tooling and spraying, existing structures mostly rely on single-axis flipping or manual handling. Tooling attitude switching depends on robotic arms or manual adjustments, making it impossible to achieve automatic switching between horizontal clamping and vertical spraying. This not only leads to low loading and unloading efficiency but also easily causes alignment errors or surface contamination due to workpiece shaking, affecting spraying quality and safety.

[0004] In terms of workpiece deflection and spraying alignment control, most equipment adopts a rigid connection structure. The bearing can only achieve a fixed angle of rotation and cannot automatically fine-tune the opposing nozzle according to the spraying position. During the spraying process, the workpiece posture is fixed, resulting in spraying dead angles and local occlusion, especially on the outer periphery and side wall areas of the blower housing, where the coating thickness distribution is uneven, affecting the product appearance and film adhesion.

[0005] Regarding rotary coating and film consistency, traditional rotary structures are mostly driven by a single motor, and the clamping mechanism uses a simple claw structure, which makes it difficult to ensure the coaxiality and balance of the workpiece. Due to the eccentricity of the rotation center or loose clamping, centrifugal deviation is easily generated during the spray coating process, resulting in problems such as uneven film thickness, over-coating at the edges, or under-coating in the center. At the same time, the nozzle arrangement of existing spray coating machines is mostly single-plane spraying, which makes it difficult to ensure the coating quality of the workpiece's sidewalls.

[0006] In view of this, we have studied and improved the existing problems and provided a rotating system for a vertical coating machine for a hair dryer housing to solve the current problems. Summary of the Invention

[0007] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0008] Therefore, the technical solution adopted in this invention is as follows: a rotating system for a vertical coating machine for a blower housing, comprising: a coating box, with a base and a coating device respectively provided on its upper and lower surfaces; a bearing assembly, including a bearing shaft, a servo motor, a tooling chuck, and a ball-head guide rod, wherein the bearing shaft is rotatably connected to the base via a wing plate seat, and the servo motor is fixed on a crank to drive the tooling chuck to rotate; and a drive assembly, including a drive rod and a connecting rod group, wherein both ends of the drive rod are movably connected to the base and the bearing shaft via a first crank and a second crank, respectively, and one end of the connecting rod group is connected to the second crank, and the other end is rotatably sleeved on the bearing shaft via a lug. The system achieves rapid switching between the tooling state and the coating processing state by extending and retracting the drive rod to drive the connecting rod group and the bearing shaft to rotate; during coating, the servo motor drives the tooling chuck to rotate, and the atomizing nozzle of the coating device sprays in alignment to form a uniform coating. Specifically, the above structure forms a composite actuator of "rotation + rotation", which ensures smooth attitude switching, accurate coating alignment, and high coating consistency.

[0009] In a preferred embodiment, the configuration is further as follows: a base and a sprayer are respectively provided on the upper and lower surfaces of the spraying box; the bearing assembly includes a bearing rod, a servo motor, a tooling chuck, and a ball-head guide rod movably connected to one end of the bearing rod; a wing plate seat is provided on the surface of the bearing rod and rotatably connected to the base; a crank is fixed to the output end of the bearing rod, and a servo motor is fixed on the crank to drive the tooling chuck to rotate; the drive assembly includes a drive rod and a connecting rod group; the two ends of the drive rod are rotatably connected to the base and the bearing rod respectively through a first crank and a second crank; one end of the connecting rod group is connected to the second crank, and the other end is rotatably sleeved onto the bearing rod through a lug, forming a stable double-link flipping mechanism; the extension and retraction of the drive rod can drive the bearing rod to flip smoothly, ensuring synchronous attitude switching and high repeatability.

[0010] In a preferred example, the configuration is further as follows: the spraying box is a sealed box structure and equipped with a dustproof curtain; the sprayer is fixed above the spraying box, and its surface is evenly distributed with several atomizing nozzles for spraying coating onto the blower housing mounted on the tooling clamp. The sealed and dustproof design significantly reduces impurity interference; the multi-nozzle array makes the spray coverage area large and the atomization uniform, improving the coating quality and consistency.

[0011] In a preferred embodiment, the bearing rod is further configured to have two postures under the control of the drive rod: a tooling state and a spraying state. In the tooling state, the bearing rod is parallel to the base, facilitating loading and unloading. In the spraying state, the bearing rod is perpendicular to the base, and the atomizing nozzle of the sprayer is perpendicular to the end face of the tooling clamp and distributed circumferentially thereafter, forming a comprehensive spray coating on the outer periphery and sides of the blower housing. This achieves process separation of "safe clamping and machining alignment," smooth flipping, and avoids uneven coating caused by vibration.

[0012] In a preferred embodiment, the configuration is further as follows: the two side flange seats of the bearing rod are rotatably mounted on the base surface and coaxially connected to the first crank shaft; one end of the connecting rod assembly is coaxial with the second crank shaft and rotatably connected to the base; both the first and second crank shafts are pin structures with eccentric lugs on their surfaces for movable connection to both ends of the drive rod. The eccentric lugs introduce nonlinear transmission characteristics, which make it easy to start with torque increase in the initial stage and stabilize the position with deceleration in the final stage, resulting in more precise rollover control and less impact.

[0013] In a preferred example, the drive rod is further configured as follows: the drive rod is an electric telescopic rod structure or a hydraulic rod structure, used to drive the first crankshaft and the second crankshaft to deflect, thereby realizing the linkage and rotation of the bearing rod and the connecting rod group. The electric type has fast response, is easy to program, and the angle can be finely adjusted; the hydraulic type has large output force and strong load resistance, and is suitable for heavy-duty tooling. Both can ensure reliable attitude switching.

[0014] In a preferred example, the linkage assembly is further configured as follows: the linkage assembly is a double-section linkage structure, with the two sections hinged together by a pivot; the two sections of the linkage are movably connected to the surface of the second crankshaft and the surface of the lug, respectively; one end of the linkage assembly is provided with a fork block connected to the second crankshaft, so that the linkage assembly can rotate freely axially; the double-section linkage improves the effective stroke and angle coverage; and the lug sleeve connecting to the bearing rod makes the movement smooth, with less wear and good centering.

[0015] In a preferred embodiment, the configuration is further as follows: a torsion spring is provided on the base surface for driving the rotation of the control ear; one end of the ball head guide rod is connected to the ball head of the control ear, and the other end is rotatably connected to the bottom end of the bearing rod; a sleeve is provided at the wing plate seat to fit the bearing rod, which, in conjunction with the traction of the ball head guide rod, allows the bearing rod to deflect at a small angle in a vertical state, providing automatic reset and micro-angle compensation, so that the tooling chuck and its clamped housing are always facing the atomizing nozzle, resulting in more complete coating coverage and more uniform thickness.

[0016] In a preferred example, the servo motor is configured as follows: the output shaft is fixedly connected to the tooling chuck to drive its rotation; the tooling chuck uses an internal expansion mechanism to cooperate with the inner wall of the blower housing to achieve positioning and clamping; the servo motor provides uniform rotation and angle control; the expansion clamping prevents eccentricity and loosening, ensuring the stability of the spraying process and the consistency of the coating.

[0017] The beneficial effects achieved by this invention are as follows:

[0018] 1. In this invention, the system has two typical working states: tooling state and spray plating state. In the tooling state, the bearing rod is arranged horizontally for clamping and disassembling the blower housing; in the spray plating state, the bearing rod is arranged vertically for vertical spray plating of the workpiece. Through automatic switching between the two working states, a clear division of labor between clamping and spray plating is achieved, resulting in a highly efficient and structurally stable overall assembly process. This avoids manual flipping and improves operational safety and production efficiency.

[0019] 2. In this invention, the drive rod, under the linkage of the first and second crank shafts and guided by the ball-head guide rod, drives the bearing rod to achieve posture flipping and axial deflection. This allows the blower housing held by the tooling chuck to smoothly deflect into the spray coating box and automatically align with the atomizing nozzle of the spray coating device during the spray coating process, achieving full coverage spraying of the outer periphery and sides of the blower housing. This structure features coordinated movement and precise angle conversion, ensuring accurate spray coating alignment and consistent film coverage.

[0020] 3. In this invention, a servo motor drives the tooling chuck to rotate, and the tooling chuck achieves coaxial clamping of the blower housing through an expansion internal support. This, combined with multiple sets of atomizing nozzles arranged on the end face and side of the plating machine for synchronous spraying, ensures uniform coating distribution on the outer periphery and side walls of the blower housing, significantly reducing thickness error, thereby reducing rework and improving product yield and coating consistency.

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0034] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0035] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a rotating system for a vertical coating machine for a hair dryer housing.

[0036] Combination Figures 1-8 As shown, the present invention provides a rotating system for a vertical coating machine for a hair dryer housing, including a coating box 100, a bearing assembly 200, and a drive assembly 300.

[0037] The upper and lower surfaces of the plating chamber 100 are respectively provided with a base 120 and a plating sprayer 130. The base 120 is the mounting base of the system, used to support the bearing assembly 200 and the drive assembly 300, ensuring the stability of the overall structure. The plating sprayer 130 is installed above the plating chamber 100 and is used to achieve coating spraying.

[0038] The bearing assembly 200 includes a bearing rod 210, a servo motor 220, a tooling chuck 230, and a ball-end guide rod 240. The bearing rod 210 is rotatably connected to the surface of the base 120 via a wing plate seat, used to drive the tooling chuck 230 to rotate, achieving a change in the orientation of the blower housing from horizontal to vertical. A sleeve is provided on the surface of the wing plate seat that fits onto the surface of the bearing rod 210, allowing the bearing rod 210 to rotate relative to the wing plate seat. Furthermore, under the traction of the ball-end guide rod 240, the bearing rod 210 can perform a certain angle of deflection when it reaches a vertical position. The servo motor 220 is fixedly mounted on the crank lug 211 and used to drive the tooling chuck 230 to rotate, causing the held blower housing to rotate during the spraying process.

[0039] The drive assembly 300 includes a drive rod 310 and a connecting rod assembly 320. The two ends of the drive rod 310 are movably connected to the base 120 and the bearing rod 210 via a first crank 311 and a second crank 312. One end of the connecting rod assembly 320 is connected to the second crank 312, and the other end is rotatably sleeved with the bearing rod 210 via an ear sleeve 330.

[0040] This structure forms a stable double-link flipping mechanism. The drive rod 310 drives the bearing rod 210 to flip smoothly through extension and retraction, realizing the rapid switching of the hair dryer shell between different postures and ensuring the synchronization and repeatability of the movement.

[0041] In this embodiment, the plating box 100 is a sealed box structure, and its outer surface is provided with a dustproof curtain 110 to prevent external dust from entering and to ensure the cleanliness of the internal plating environment. The plating device 130 is fixedly installed on the top of the plating box 100, and its surface is evenly distributed with several atomizing nozzles 131 for spraying plating material.

[0042] The combination of a sealed enclosure and a dustproof curtain 110 effectively seals the plating environment, reducing interference from airborne impurities and improving the surface quality of the plating layer. Multiple atomizing nozzles 131 spray simultaneously, ensuring uniform plating distribution, making it suitable for full-coverage plating of cylindrical parts such as hair dryer housings.

[0043] In this embodiment, the bearing rod 210 forms two typical states under the control of the drive rod 310: the first state is the tooling loading and unloading stage: the bearing rod 210 is parallel to the base 120;

[0044] The second state is the spray plating process stage: the bearing rod 210 is perpendicular to the base 120.

[0045] In the spray coating process, the atomizing nozzles 131 on the surface of the spray coating machine 130 are vertically and circumferentially distributed on the surface of the tooling clamp 230, so as to achieve uniform spray coating on the outer peripheral surface and side of the blower housing.

[0046] The switchable structure with two states separates the clamping and plating processes, ensuring clamping safety while improving plating efficiency. The flipping action is smooth and reliable, avoiding uneven plating thickness caused by workpiece vibration.

[0047] In this embodiment, the two side flange seats of the bearing rod 210 are rotatably mounted on the surface of the base 120 and coaxially connected to the first crank shaft 311; one end of the connecting rod assembly 320 is coaxially connected to the second crank shaft 312 and rotatably connected to the surface of the base 120. Both the first crank shaft 311 and the second crank shaft 312 are pin structures, and their surfaces are provided with eccentrically arranged lugs for movably connecting to both ends of the drive rod 310.

[0048] By using the design of the eccentric lug, the drive rod 310 can form a non-linear transmission effect during the extension and retraction process, so that the first crank shaft 311 and the second crank shaft 312 can be deflected and driven, improving the starting force of the initial stage of the flip and the braking accuracy of the final stage, and achieving more precise angle control of the bearing rod 210 and smoother mechanical response.

[0049] In this embodiment, the drive rod 310 is an electric telescopic rod or a hydraulic rod structure, used to drive the first crank shaft 311 and the second crank shaft 312 to deflect, so as to realize the linkage and flipping of the bearing rod 210 and the connecting rod group 320.

[0050] The electric telescopic rod offers fast response and high control precision, enabling precise adjustment of the bearing rod angle up to 210 degrees to meet the angle requirements of different plating processes. The hydraulic drive provides higher output force and is suitable for heavy-duty tilting of large-sized tooling.

[0051] In this embodiment, the connecting rod assembly 320 adopts a double-section connecting rod structure. The two sections of the connecting rod are hinged together by a pivot. One end is connected to the second crank shaft 312, and the other end is movably connected to the bearing rod 210 through an ear sleeve 330. The ear sleeve 330 is fitted onto the outer surface of the bearing rod 210, allowing it to rotate around the bearing rod.

[0052] In this embodiment, the base 120 surface is provided with a torsion spring for driving the control ear 241 to rotate, one end of the ball head guide rod 240 is connected to the ball head of the control ear 241, and the other end is rotatably connected to the bottom end of the bearing rod 210.

[0053] This structure provides automatic reset and angle compensation functions. When the bearing rod 210 flips, the ball head guide rod 240 provides support and minor correction. Under the traction of the ball head guide rod 240, the bearing rod 210 can rotate to a certain angle in a vertical state, so that the tooling clamp 230 and the fan housing of the tooling on its surface face the atomizing nozzle 131. The atomizing nozzles 131 located on the bottom and side surfaces of the sprayer 130 face the outer periphery and side surfaces of the fan housing, respectively.

[0054] In this embodiment, the servo motor 220 is a motor-driven structure, and its output shaft is fixedly connected to the tooling chuck 230 to drive the tooling chuck 230 to rotate. The tooling chuck 230 achieves positioning and fixation of the inner wall of the blower housing through an internal tensioning mechanism.

[0055] The servo motor 220 enables precise rotation control, ensuring the blower housing rotates at a uniform speed during the spraying process, thus improving coating uniformity. The expansion clamping structure prevents workpiece loosening or eccentricity, guaranteeing the stability of the spraying process.

[0056] Working principle and usage process of this invention:

[0057] The present invention relates to a rotating system for a vertical coating machine for a hair dryer housing. It is mainly composed of a spray coating box 100, a bearing assembly 200, and a drive assembly 300. Through the linkage of the linkage mechanism and the precise control of the servo motor 220, the automatic switching of the hair dryer housing between two working states is realized, namely the tooling state and the spray coating processing state.

[0058] The plating box 100 is a sealed box structure with a base 120 at the bottom and a plating device 130 mounted on the top. The surface of the plating device 130 is evenly distributed with several atomizing nozzles 131 for omnidirectional plating of the blower housing. The bearing assembly 200 is rotatably connected to the base 120 via a bearing rod 210. The upper end of the bearing rod 210 is fixed with a servo motor 220 and a tooling clamp 230. The tooling clamp 230 is used to clamp the inner wall of the blower housing to achieve rotary plating.

[0059] The drive assembly 300 consists of a drive rod 310, a first crank shaft 311, a second crank shaft 312, a connecting rod assembly 320, and an ear sleeve 330. The drive rod 310 is movably connected to the base 120 and the bearing rod 210 via the crank shafts at both ends. The connecting rod assembly 320 connects the bearing rod 210 and the second crank shaft 312, forming a complete linkage transmission mechanism. Through the extension and retraction of the drive rod 310, the bearing rod 210 can be driven to rotate around the base 120, thereby achieving posture adjustment at different angles.

[0060] Based on operational requirements, the system of this invention has two typical working states: tooling state and spray coating processing state.

[0061] 1. Tooling and workpiece loading / unloading stage:

[0062] In the tooling state, the drive rod 310 is in a retracted state, the connecting rod assembly 320 is folded, and the bearing rod 210 and the surface of the base 120 are arranged in an approximately horizontal relationship.

[0063] In this state, the tooling chuck 230 faces upward and is located outside the spraying box 100, facilitating the installation or removal of the blower housing by the operator or robotic arm. The ball head guide rod 240 and the control ear 241 are in an initial equilibrium position under the reset action of the torsion spring, providing support for the next angle conversion.

[0064] In this state:

[0065] Servo motor 220 is in standby mode, and tooling chuck 230 remains stationary;

[0066] After the workpiece is clamped, the blower housing is fixed to the fixture chuck 230 by an air expansion mechanism or mechanical locking device; all atomizing nozzles 131 are closed, and the airflow circulation system inside the plating box 100 is in standby mode. This structural design ensures the stability and safety of the fixture clamping process, preventing the workpiece from shaking or slipping during loading and unloading.

[0067] 2. Spray coating process, spin coating stage:

[0068] When entering the spray plating stage, the drive rod 310 begins to extend. Through the eccentric linkage of the first crankshaft 311 and the second crankshaft 312, it drives the connecting rod group 320 and the ear sleeve 330 to work together, so that the bearing rod 210 gradually flips from the horizontal position to the vertical state, perpendicular to the surface of the base 120.

[0069] at this time:

[0070] The bearing rod 210 drives the servo motor 220 and the tooling chuck 230 to rotate to a vertical position and enter the spraying box 100; the servo motor 220 starts, driving the tooling chuck 230 to rotate, thereby driving the blower housing to rotate.

[0071] The atomizing nozzle 131 on the sprayer 130 is turned on simultaneously to spray coating material and form a uniform coating along the outer peripheral surface of the blower housing.

[0072] During the spraying process, the ball head guide rod 240 and the control ear 241 generate micro-angle compensation, causing the bearing rod 210 to rotate to a vertical angle. The bearing rod 210 can rotate and deflect at a certain angle, so that the tooling clamp 230 and the fan housing of the tooling on its surface face the atomizing nozzle 131. The atomizing nozzles 131 located on the bottom and side surfaces of the sprayer 130 face the outer periphery and side surfaces of the fan housing, respectively.

[0073] After the spraying is completed, the servo motor 220 stops rotating, the drive rod 310 retracts in the opposite direction, and the bearing rod 210 returns to the horizontal position under the traction of the connecting rod group 320. The system returns to the tooling state and waits for the next cycle of operation.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
