Description

Technical Field

[0001] This utility model belongs to the field of robot manufacturing technology, and in particular relates to a dip coating equipment for robot manufacturing. Background Technology

[0002] Dip coating is a key surface treatment process in robot manufacturing. It involves completely immersing the workpiece in a coating bath, utilizing the coating's gravity and flowability to achieve uniform coverage. The core of this process lies in controlling the coating viscosity, immersion time, and workpiece removal speed to ensure consistent coating thickness and the absence of air bubbles. In robot production, dip coating is widely used for protective coatings on metal structural components, joint parts, or electronic components. For example, the aluminum alloy frame of a robotic arm often uses epoxy resin dip coating to enhance corrosion resistance, while circuit boards may be waterproofed and insulated using polyurethane coatings. Compared to spraying or brushing, dip coating offers advantages such as high material utilization (coating loss rate less than 10%) and the ability to fully cover complex structures, making it particularly suitable for mass production.

[0003] Comparing with Chinese Patent CN221157479U, a dip-coating fixture for robot production is disclosed, including a mounting plate, a stepper motor, a cover plate, bolts, and a housing. The stepper motor is fixedly mounted on the bottom surface of the mounting plate, and the cover plate is fixedly sleeved on the output shaft of the stepper motor. Bolts are threaded onto the cover plate, and hooks are threaded onto the cover plate via the bolts. A buckle is threaded onto the housing via bolts. Opening the stepper motor causes its output shaft to rotate the cover plate to a specified angle, thereby adjusting the clamping angle and facilitating dip-coating of robot parts. This expands the applicability and enhances the practicality of the dip-coating fixture. The buckle is pried open to separate the hooks, the cover plate is removed from the housing, the coupling is rotated to separate it from the cylinder and connecting shaft, the rotating shaft is rotated to separate it from the housing, and the corresponding threaded rod is unscrewed. This saves time and effort, improves maintenance efficiency, and enhances the convenience of maintenance and disassembly.

[0004] However, the aforementioned patented clamping robot for dip coating is prone to dead corners of paint coverage at the clamping point, and static dip coating is prone to uneven coating thickness. In addition, after dip coating is completed, other equipment needs to be used for clamping and subsequent processing to free up the workstation for the next robot dip coating operation, which seriously affects the efficiency of robot dip coating production. Therefore, a new device needs to be designed. Utility Model Content

[0005] The purpose of this invention is to provide a dip coating device for robot production, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A robot-based dip-coating device includes a tank assembly for holding paint liquid for dip-coating, and a walking assembly mounted on the tank assembly for movement. The walking assembly is equipped with a suspension assembly for suspending and lifting the robot. The tank assembly includes a fixed foundation with a tank body located in the center. Two limiting guide rails are symmetrically arranged on the fixed foundation. The walking assembly includes two symmetrically arranged support bases, each with two symmetrically mounted wheels. At least one wheel on each support base is equipped with a walking motor. A gantry frame is located between the tops of the two support bases. The suspension assembly includes a drive shaft with a servo motor at one end and a lifting mechanism mounted in the middle of the drive shaft.

[0008] Furthermore, control boxes and batteries are symmetrically installed on both sides of the gantry frame.

[0009] Furthermore: the gantry frame and the support base are welded together, and the traveling motor and the support base are bolted together.

[0010] Furthermore, the lifting mechanism includes a winding reel with a steel cable wound on it, and a suspension hook is installed at the bottom end of the steel cable.

[0011] Furthermore, there are two lifting mechanisms, symmetrically distributed along the axial direction of the transmission shaft and connected by a flat key.

[0012] Furthermore, the tank body is elongated and its depth is greater than the height of the gantry frame.

[0013] Furthermore: the limiting guide rail is made of 45 steel and is distributed parallel to both sides of the tank body, with both ends of the limiting guide rail protruding from both ends of the tank body.

[0014] Compared with existing technologies, the beneficial effects are:

[0015] 1. Through the linkage design of the gantry and the walking components, the robot can be dip-coated while moving, ensuring that the paint covers all corners without dead angles, avoiding the uneven thickness problem caused by traditional static dip-coating, and solving the problems of low efficiency and poor uniformity of traditional dip-coating equipment. It is especially suitable for the surface treatment needs of large or irregularly shaped robots.

[0016] 2. The dual lifting mechanisms are symmetrically distributed to balance the robot's suspension posture, ensuring stable rotation of the robot within the gantry and preventing coating deviations caused by tilting during coating. The modular lifting mechanism supports quick maintenance or load adjustment to adapt to robots of different sizes.

[0017] 3. The walking motor and servo motor work together to automatically complete the closed-loop operation of "positioning-lifting-dipping-removal", realizing full-process electrification of walking, lifting and dipping, reducing manual intervention and improving production efficiency.

Two limiting guide rails 103 are symmetrically arranged on the fixed base 101. The tank body 102 is a long tank with a depth greater than the height of the gantry frame 202. The limiting guide rails 103 are made of 45 steel and are distributed parallel to both sides of the tank body 102, with both ends of the limiting guide rails 103 protruding from both ends of the tank body 102. The rotating wheels 203 drive the gantry frame 202 to move on the fixed base 101 and move across the tank body 102 along the limiting guide rails 103, allowing the robot to be immersed in the paint liquid from one end of the tank body 102 for dipping and coating. The robot moves at the same time to ensure the comprehensiveness and uniformity of the dipping and coating. When the robot reaches the other end of the tank body 102, it is lifted up and suspended inside the gantry frame 202 for convenient subsequent operations.

[0028] In this embodiment: the walking assembly includes two symmetrically arranged support bases 201, each support base 201 has two symmetrically installed walking wheels 203, and at least one walking wheel 203 on each support base 201 is equipped with a walking motor 204. A gantry frame 202 is arranged between the tops of the two support bases 201; a control box 205 and a battery 206 are symmetrically installed on both sides of the gantry frame 202; the gantry frame 202 and the support bases 201 are welded together, and the walking motor 204 is bolted to the support bases 201; the control box 205 controls the battery 206 to supply power, and the support bases 201 support the walking motor 204 to drive the walking wheels 203 to rotate and drive the gantry frame 202 to move.

[0029] In this embodiment: the suspension assembly includes a drive shaft 301, one end of which is equipped with a servo motor 302, and a lifting mechanism is installed in the middle of the drive shaft 301; the lifting mechanism includes a winding wheel 303, on which a steel cable 304 is wound, and a suspension hook 305 is installed at the bottom end of the steel cable 304; there are two lifting mechanisms, symmetrically distributed along the axial direction of the drive shaft 301, and connected by a key; the servo motor 302 drives the drive shaft 301 to drive the winding wheel 303 to rotate in both directions, and the robot is lowered or lifted by the steel cable 304.

[0030] Working principle: The control box 205 controls the battery 206 to supply power. First, the support base 201 supports the walking motor 204, which drives the walking wheels 203 to rotate, moving the gantry 202 above the robot. Then, the servo motor 302 drives the drive shaft 301 to rotate the winding wheel 303, releasing the steel cable 304. The robot is then hooked by the suspension hook 305. Afterward, the servo motor 302 drives the drive shaft 301 to reverse the winding wheel 303, winding the steel cable 304. The robot is then lifted into the gantry 202 by the suspension hook 305.
