Technical Field

[0002] In mechanical processing, the robot arm is a common mechanical equipment that can be used for processing, material transfer, etc. It can complete some dangerous and highly repetitive tasks and is widely used in the manufacturing industry. The robot arm usually uses one or more arms connected in sequence, each of which is equipped with a motor. The motor is used to achieve relative movement between the two arms, thereby achieving similar movements in various degrees of freedom.

[0003] During the installation and use of the robotic arm, it is necessary to fix the robotic arm to one side of the production line through a base so that the robotic arm can be applied. However, the existing robotic arm has a large range of motion during use, which can easily injure people around the robotic arm. Therefore, the robotic arm is generally protected during use. Most of the existing protective devices are guardrails placed on the ground during use. When workers lean against or are hit by vehicles pushing materials, they are prone to displacement, resulting in a smaller protection range or a collision after the guardrail overlaps with the working range of the robotic arm, damaging the robotic arm. The use of guardrails fixed to the ground makes it inconvenient to adjust the robotic arm and the working production line where the robotic arm is located. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the existing mobile robotic arm protection device cannot effectively prevent the movement of the protection device when in use, thereby posing a certain risk of collision to personnel and the robotic arm.

[0006] As an improvement, the bracket is composed of a mounting plate, a support rod and a connecting block, the two ends of the support rod are respectively connected to the mounting plate and the connecting block, and the support rod is arranged parallel to the ground. The top of the support rod is fixedly connected to the top of the mounting plate through a reinforcing rod, the mounting plate is fixedly connected to the back of the first guardrail, and the connecting block is slidably connected to the mounting slot.

[0007] As an improvement, the height of the connecting block is 1 / 2 of the installation slot, and positioning blocks are provided on both sides of the interior of the installation slot at the lower 1 / 2, corresponding positioning grooves are provided on both sides of the connecting block at the positioning blocks, and a filling plate is provided above the installation slot at the connecting block.

[0008] As an improvement, the interior of the first guardrail is a hollow structure, and a plurality of bracket plates are arranged inside the first guardrail, and the bracket plates are provided with through holes matching the shapes of the plurality of guide rods.

[0009] As an improvement, the plurality of limit slots on the guide rod are linearly and equidistantly arranged, and the depth of the plurality of limit slots is less than 1 / 2 of the diameter of the guide rod.

[0014] 1.
