Description

Technical Field

[0001] This utility model relates to the field of automation technology of powder metallurgy presses, specifically to a safety protection device for a powder metallurgy press robot arm. Background Technology

[0002] With the advancement of technology, industrial production has gradually become more reliant on automated equipment to replace manual operations. Among these, robotic arms have been widely used due to their flexibility and efficiency. However, in actual operation, safety issues have become an indispensable aspect.

[0003] Robot arm guardrails are safety protection facilities used around mechanical equipment. They serve as safety warnings and protections for robot operators, as well as to isolate and protect the machine and play a role in the rational planning of the area.

[0004] Currently, most guardrails on the market are ground-mounted, consisting of posts and a grid surface, and are fixed to the area around the equipment with expansion bolts. This results in a large footprint, lack of flexibility, and inconvenience for changing equipment models.

[0005] The press equipment is equipped with a safety door when it leaves the factory, but it loses its safety protection function when it is automated with a robotic arm, so an additional robotic arm safety device needs to be installed. Utility Model Content

[0006] The purpose of this utility model is to overcome the problems existing in the prior art and provide a safety protection device for the robot arm of a powder metallurgy press.

[0007] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0008] A safety protection device for a powder metallurgy press robot includes a pair of lateral isolation fences. One side of each lateral isolation fence is mounted on a guide block, which is slidably connected to a guide post. The guide post is used to fix the robot to a corresponding frame near the powder metallurgy press robot. A plurality of lateral isolation fences are connected between the other sides of the two lateral isolation fences to form a robot protection area.

[0009] Furthermore, one side of the lateral isolation fence is fixed to the guide block via a connecting plate.

[0010] Furthermore, the guide post has a hollow structure, within which a counterweight is slidably placed. The counterweight is suspended from the lateral and / or lateral isolation fences by corresponding ropes, facilitating counterweight balance when the guide post is installed vertically.

[0011] Furthermore, the lateral and lateral isolation fences are made by welding wire mesh and frame profiles.

[0012] Furthermore, the endo-directional isolation fence is a single unit, and the endo-directional isolation fence is vertically connected to the lateral isolation fence to form a rectangular protection area.

[0013] The beneficial effects of this utility model are:

[0014] After adopting the press robot protection device of this utility model, the equipment can continuously, stably and safely use the robot. Since the protection device completely encloses the entire operating area of ​​the robot, it has the advantages of high safety, good flexibility, low cost, simple operation and high practicality compared with the traditional ground-mounted guardrail.

[0016] Figure 2 This is a schematic diagram of the vertical installation state of this utility model.

[0017] The labels in the diagram are as follows: 1. Lateral isolation fence, 2. Guide block, 3. Guide post, 4. End isolation fence, 5. Connecting plate. Detailed Implementation

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] like Figure 1 As shown, a safety protection device for a powder metallurgy press robot includes a pair of lateral isolation fences 1. One side of each lateral isolation fence 1 is mounted on a guide block 2. The guide block 2 is slidably connected to a guide post 3. The guide post 3 is used to fix the robot to a corresponding frame near the powder metallurgy press robot. A plurality of lateral isolation fences 4 are connected between the other sides of the two lateral isolation fences 1 to form a robot protection area.

[0020] One side of the lateral isolation fence 1 is fixed to the guide block 2 by the connecting plate 5.

[0021] The guide post 3 is a hollow structure, within which a counterweight is slidably placed. The counterweight is suspended from the lateral isolation fence 1 and / or the lateral isolation fence 4 by corresponding ropes, facilitating counterweight balance during the vertical installation of the guide post 3. During installation, if... Figure 2As shown, the guide post 3 is vertically fixed on the corresponding frame near the robot arm of the powder metallurgy press. Upper and lower limit blocks can be set on the frame or guide post 3 to limit the vertical position of the isolation fence. In some commonly used stroke positions, pin holes and pin structures can be set on the guide post 3 to fix the vertical position. Under normal protection conditions, the isolation fence is suspended in the air. When the robot arm needs to be inspected or upgraded, the staff can pull out the pin. With the balance of the counterweight, the staff can easily push and pull the isolation fence along the guide post 3 vertically. For example, the isolation fence can be pushed upward to expose the robot arm area. Then, the staff can enter the area to perform product replacement, repair, maintenance, upgrade and other work. After the work is completed, the staff can walk out of the robot arm area, pull down the isolation fence and fix the position with the pin.

[0022] The lateral isolation fence 1 and the lateral isolation fence 4 are made of steel wire mesh and frame profiles welded together.

[0023] The endo-direction isolation fence 4 is a single unit, and the endo-direction isolation fence 4 is vertically connected to the lateral isolation fence 1 to form a rectangular protection area.

[0024] The following methods can be used during the actual production and installation:

[0025] 1. Determine the robot's operating area based on the type of robot arm that matches the press equipment's tonnage and its working path;

[0026] 2. The materials are lightweight alloy profiles, hollow tubes, and steel wire mesh, which are welded and processed, and then polished, rust-proofed, and painted. The paint surface can be a bright color such as yellow.

[0027] 3. Install the completed device on the corresponding press, and select the counterweight according to the weight of the isolation fence to ensure that the isolation fence moves up and down freely without jamming.

[0028] 4. The isolation fence can be moved up and down to facilitate safe entry and exit for operators, product changeover, maintenance, and other work.

[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
