Description

Technical Field

[0001] This utility model belongs to the field of robotic arm technology, specifically, it relates to a waterproof structure for a robotic arm mounting plate. Background Technology

[0002] In practical applications of robotic arms, moisture intrusion into the equipment is a pressing issue. Moisture entry can cause short circuits in internal electronic components and corrosion of metal parts, thus affecting normal operation, shortening equipment lifespan, and increasing maintenance costs. Current waterproofing solutions, such as using sealing gaskets at the interface between the robotic arm and other components, only provide waterproofing to specific joints with limited effectiveness. Another method, using a double-layered pot, is costly and unsuitable for waterproofing robotic arm mounting plates. Furthermore, some robotic arm waterproofing structures struggle to maintain a proper seal during robotic arm movement, failing to effectively prevent moisture intrusion. Therefore, developing an efficient, reliable, and cost-effective waterproofing structure for robotic arm mounting plates is of significant practical importance. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the purpose of this invention is to provide a waterproof structure for a robotic arm mounting plate.

[0004] According to the present invention, a waterproof structure for a robotic arm mounting plate includes a mounting plate, a drive device, and a waterproof cover. The mounting plate is fixedly mounted on the top of the drive device, the drive device is disposed inside a housing, and the waterproof cover is mounted on the mounting plate.

[0005] The waterproof cover includes a waterproof outer cover and a waterproof inner cover, which are nested and interlocked to form a double-layered sealed structure that isolates moisture.

[0006] In a preferred embodiment: the waterproof cover is disposed on the top of the housing, and the waterproof cover isolates the space above the mounting plate from the working area.

[0007] In a preferred embodiment: both the mounting plate and the waterproof cover are provided with mounting holes, through which the robotic arm is fixed above the mounting plate.

[0008] In a preferred embodiment: the edge of the waterproof inner cover extends toward the mounting plate, and the edge of the waterproof outer cover extends toward the housing.

[0009] In a preferred embodiment: both the waterproof outer cover and the waterproof inner cover are made of stainless steel or engineering plastic, and have corrosion resistance and wear resistance.

[0010] In a preferred embodiment: the lower surface of the waterproof outer cover and the inner circumference of the waterproof inner cover are coated with an elastic rubber material, and the slight gaps generated when the mounting plate moves will be compensated by the deformation of the elastic material.

[0011] In a preferred embodiment: as the waterproof outer cover moves synchronously with the mounting plate, the waterproof outer cover always remains in contact with or overlaps with the waterproof inner cover.

[0012] In a preferred embodiment, the length of the overlapping area between the waterproof outer cover and the waterproof inner cover is greater than the lifting stroke of the drive device.

[0013] In a preferred embodiment: the waterproof inner cover and the waterproof outer cover respectively cover the outer area of ​​the drive device.

[0014] In a preferred embodiment: the waterproof inner cover and the box body, and the waterproof outer cover and the mounting plate are all fixedly connected by bolts, and the gaps are filled with sealant.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] When in use, this utility model forms a multi-layered sealing barrier through the overlapping design of the waterproof inner and outer covers. It fits tightly when static and maintains continuous contact when dynamic, effectively preventing moisture from entering the equipment. It is suitable for humid environments and improves the reliability of the equipment.

[0017] When this utility model is in use, the waterproof cover rises and falls synchronously with the mounting plate, and the length of the overlapping area is greater than the stroke, ensuring that the seal is not interrupted during the lifting and lowering of the robotic arm, solving the problem of failure of traditional static seals in motion scenarios, and ensuring long-term stable operation of the equipment.

[0025] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0026] like Figure 1-3 As shown, this utility model discloses a waterproof structure for a robotic arm mounting plate, including a mounting plate 1, a drive device 3, and a waterproof cover 2. The mounting plate 1 is fixedly installed on the top of the drive device 3, which is located inside the housing 12. The waterproof cover 2 is installed on the mounting plate 1 and is located on the top of the housing 12. The waterproof cover 2 is used to isolate the robotic arm 11 from the humid environment of the working area. Both the mounting plate 1 and the waterproof cover 2 have mounting holes, through which the robotic arm 11 is fixed above the mounting plate 1.

[0027] The waterproof cover 2 includes a waterproof outer cover 15 and a waterproof inner cover 16. The edge of the waterproof inner cover 16 extends towards the mounting plate 1, and the edge of the waterproof outer cover 15 extends towards the housing 12. The waterproof outer cover 15 and the waterproof inner cover 16 are nested and staggered to form a double-layer sealed structure that isolates moisture. Both the waterproof outer cover 15 and the waterproof inner cover 16 are made of stainless steel or engineering plastic, which has corrosion resistance and wear resistance. The lower surface of the waterproof outer cover 15 and the inner ring surface of the waterproof inner cover 16 are coated with elastic rubber material. When the mounting plate 1 moves, the small gaps will be compensated by the deformation of the elastic material. As the waterproof outer cover 15 moves synchronously with the mounting plate 1, the extension of the waterproof outer cover 15 and the waterproof inner cover 16 are always in contact and sealed. The waterproof inner cover 16 and the waterproof outer cover 15 respectively cover the outer area of ​​the drive device 3. The waterproof inner cover 16 and the housing 12, and the waterproof outer cover 15 and the mounting plate 1 are all fixedly connected by bolts and sealed with sealant.

[0028] Working principle

[0029] In use, the waterproof inner cover 16 is fixed to the housing 12, and the waterproof outer cover 15 is fixed to the mounting plate 1. The two are designed to be interlocked. When the housing 1 is stationary, the interlocking area of ​​the waterproof outer cover 15 and the waterproof inner cover 16 forms a static seal to prevent water intrusion. When the mounting plate 1 is driven by the drive device 3 to raise and lower the robotic arm 11, the waterproof outer cover 15 moves synchronously with the mounting plate 1, always maintaining contact or overlap with the waterproof inner cover 16, and the length of the overlap area is greater than the lifting stroke, ensuring that the seal is not interrupted during dynamic processes. The waterproof cover 2 is made of corrosion-resistant material, in which the coated elastic material can compensate for small gaps, and the rigid material maintains the seal through structural design, achieving a statically reliable and dynamically continuous waterproof effect. It is suitable for scenarios where the robotic arm 11 frequently raises and lowers, effectively protecting the inside of the equipment from water intrusion.
