[0026] Reference Figure 1-3 This utility model provides an industrial robot collision protection device, comprising:

[0027] The main unit 100 includes a base plate 101, on which a connecting base 102 is provided. The base plate 101 assists in the placement of the industrial robot, and the connecting base 102 facilitates the connection and operation with the industrial robot.

[0028] The protective unit 200 includes a base block 201, which is fixedly connected to the base plate 101. Horizontal plates 202 are fixedly connected to the four sides of the base block 201. Springs 203 are fitted on each of the four horizontal plates 202. Protective plates 204 are slidably connected to each of the four horizontal plates 202. Buffer strips 205 are fixedly connected to each of the four protective plates 204. A fixing component 206 is commonly provided on the four horizontal plates 202. The force of the springs 203 causes the protective plates 204 to protect the industrial robot, preventing obstacles from colliding with the industrial robot and causing malfunctions or damage. The buffer strips 205 also reduce the impact of collisions with the industrial robot, greatly improving the protective effect of the industrial robot.

[0029] The fixing component 206 includes four movable plates 206a, which are slidably connected to the corresponding horizontal plates 202. The base plate 101 has four movable openings 206b. Clamping plates 206c are fixedly connected to each of the four movable plates 206a, and multiple anti-slip blocks 206d are fixedly connected to each of the four clamping plates 206c. Through the force of the spring 203 on the other side, the movable plates 206a drive the clamping plates 206c to fix the connecting base 102, thereby realizing the quick and convenient installation of the industrial robot. The anti-slip blocks 206d prevent the industrial robot from loosening during fixing, thus strengthening the connection between the equipment.

[0030] Furthermore, the two ends of the four springs 203 are fixedly connected to the protective plate 204 and the movable plate 206a respectively. The four movable plates 206a are all movably set in the corresponding movable openings 206b. The multiple anti-slip blocks 206a are all in contact with the connecting base 102 and are fixed by the two ends of the springs 203 to prevent bending when compressed. They are also movable in the movable openings 206b through the movable plates 206a, which facilitates the guiding movement of the movable plates 206a and ensures the stable translation of the clamping plate 206c.

[0031] Furthermore, a circular plate 207 is fixedly connected to the side of the base block 201 away from the base plate 101. An electromagnetic coil 208 is fixedly connected to the outer ring of the circular plate 207. Magnetic blocks 209 are fixedly connected to each of the four movable plates 206a. The electromagnetic coil 208 generates a magnetic force that repels the magnetic blocks 209, making it easier for personnel to disassemble the industrial robot. Conversely, the electromagnetic coil 208 can be turned off, reducing the workload of personnel.

[0032] Furthermore, a cross plate 210 is fixedly connected to the side of the circular plate 207 away from the base plate 101. Multiple casters 211 are rotatably connected to the cross plate 210. The multiple casters 211 facilitate the movement and operation of the protective device, eliminating the need for manual handling of the entire device, thus saving time and effort.

[0033] Furthermore, the base plate 101 is threaded with two positioning plates 212. The bottom surface of both positioning plates 212 is provided with anti-slip texture. By rotating the positioning plates 212, they are brought into contact with the ground, which has the effect of positioning and fixing the equipment, avoiding secondary collisions caused by collisions.

[0034] During use, the protective plates 204 around the perimeter are unfolded by the force of the spring 203, forming an effective protective barrier for the industrial robot and preventing obstacles from contacting and colliding with the industrial robot. This effectively avoids the risk of malfunction and damage to the industrial robot caused by collisions. At the same time, the buffer strip 205 weakens the impact force on the robot, greatly improving the overall protective performance of the equipment. The reverse force generated by the spring 203 can push the movable plate 206a to move, thereby causing the clamping plate 206c to fit tightly against the connecting base 102, achieving rapid and stable installation of the industrial robot.

[0035] The electromagnetic coil 208 generates a magnetic force that repels the magnetic block 209, making it easier for personnel to disassemble the industrial robot. Conversely, the electromagnetic coil 208 is turned off to eliminate the magnetic force, reducing the workload of personnel. At the same time, multiple casters 211 facilitate the movement of the protective device without the need for manual handling, saving time and effort. By rotating the positioning plate 212, it is brought into contact with the ground, providing a positioning and fixing effect for the equipment and preventing secondary collisions caused by movement.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
