Abstract
Description
Technical Field
[0001] This utility model relates to the field of cleaning machine technology, and in particular to a feed track for a deformation-resistant cleaning machine robotic arm. Background Technology
[0002] In ultrasonic cleaning machines, the design of the robotic arm and its movement system plays a crucial role in improving cleaning efficiency and process quality. The linear guide rail and slider system provides micron-level repeatability, ensuring that the robotic arm accurately places the workpiece into the cleaning tank via the lifting frame, avoiding uneven cleaning or collisions caused by misalignment.
[0003] The existing linear guides used for robot movement are circular linear guides, which have low movement accuracy. The circular linear guides involve point contact between the ball bearings and the circular track, resulting in local stress concentration, which can easily lead to deformation and decreased accuracy. This can cause the robot to collide with the frame during the movement of the lifting frame, affecting the cleaning quality. Utility Model Content
[0004] The purpose of this utility model is to provide a feed track for a robot arm of a deformation-resistant cleaning machine, so as to solve the problem that the hanging frame is prone to collision during the movement of the robot arm through the existing circular rail.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a feed track for a deformation-resistant cleaning machine robotic arm, comprising:
[0006] The drive module includes a mounting bracket and a linear rail. The linear rail is fixedly installed in the mounting bracket. The linear rail is a square linear rail and includes a track and a slider. The cross-section of the track is "I" shaped, and the slider is slidably connected to the track.
[0007] The robotic arm body includes a hanging rod, a frame, and a hook. The hanging rod is fixedly installed on the slider, the frame is fixedly installed at the bottom of the hanging rod, a first lateral reinforcing rib is provided between the frame and the hanging rod, and the hook is fixedly installed on the frame.
[0008] As a further description of the above technical solution:
[0009] On the frame with hook thread connection.
[0010] As a further description of the above technical solution:
[0011] A second reinforcing rib is provided on the suspension rod.
[0012] As a further description of the above technical solution:
[0013] The mounting bracket surface is provided with arc-shaped ribs arranged along its own length, and the ribs contact the frame.
[0014] As a further description of the above technical solution:
[0015] The arc-shaped ribs are inserted into the grooves on the surface of the mounting bracket.
[0016] As a further description of the above technical solution:
[0017] The mounting bracket contains two parallel linear guides.
[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0019] 1. In this utility model, the linear guide in the drive module is a square linear guide. The square linear guide adopts a ball bearing and track surface contact design, which increases the contact area and makes the load distribution more uniform.

[0020] 2. In this utility model, the robotic arm body is mounted on the slider to achieve reciprocating movement in the vertical direction, thereby driving the lifting frame to move up and down.
