Description

Technical Field

[0001] The utility model relates to the technical field of spraying robots, in particular to a protective cover for a spraying robot. Background Art

[0002] Spraying robots are industrial robots that can automatically spray paint or other coatings. They are widely used in automotive, instrumentation, electrical appliances, enamel and other process production departments. In order to prevent the spraying materials from splashing onto the surface and inside of the robot and causing damage, a protective cover is needed to wrap the robot. However, there are still some problems with the existing spraying robot protective covers.

[0003] The existing spraying robots use four-axis or six-axis rotation, which places extremely high requirements on the protective cover. If the protective cover is wrapped too tightly, it is easy to wear and tear when rotating horizontally and vertically at the same time. If the wrapping is loose, it is easy to get entangled and stuck in the rotating axis of the robot, which is very inconvenient to use. For this reason, we propose a protective cover for the spraying robot. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the utility model provides a protective cover for a spraying robot. A strong magnetic block is set to fix the rotating seat and the protective cover, and the protective cover is then fixed to the outer movable ring through a fixed ring. There are balls between the outer movable ring and the inner ring, which can rotate freely. When the rotating seat rotates, the protective cover can rotate together with the rotating seat, reducing the entanglement caused by rotation in one direction, avoiding the protective cover from being drawn into the rotating shaft during the multi-directional rotation of the robot, and greatly improving the service life of the protective cover.

[0005] To solve the above technical problems, the utility model provides the following technical solutions: a protective cover for a spraying robot, comprising a base, a rotating seat is rotatably connected to the top of the base, a protective cover is sleeved on the surface of the rotating seat, an inner ring is fixedly connected to the surface of the base, an outer movable ring is rotatably connected to the surface of the inner ring, a ball is arranged at the connection between the inner ring and the outer movable ring, a limiting groove is arranged on one side surface of the outer movable ring, a fixing ring is sleeved on the surface of the outer movable ring, a clamping groove is arranged on the inner wall of the fixing ring, a spring is arranged on the inner side of the clamping groove, a clamping block is arranged on one side of the spring, one end of the clamping block passes through the clamping groove and is located on the inner side of the limiting groove, the surface of the fixing ring is fixedly connected to the protective cover, a strong magnetic groove is arranged on the surface of the rotating seat, a strong magnetic block is arranged on the inner side of the strong magnetic groove, one end of the strong magnetic block passes through the strong magnetic groove and is located on the outer side of the rotating seat, and one end of the strong magnetic block is fixedly connected to the protective cover.

[0007] Preferably, the number of the elastic bands is three.

[0008] Preferably, there are two strong magnetic blocks, which are symmetrically distributed on both sides of the rotating base.

[0009] Preferably, a first ball groove is formed on the surface of the inner ring, and a second ball groove is formed on the inner wall of the outer movable ring.

[0010] Preferably, there are three clamping blocks in total, and the three clamping blocks are distributed in a ring-like shape and at equal distances on the inner side of the fixing ring.

[0021] In order to prevent the spraying material from splashing onto the surface and inside of the robot, it is necessary to use a protective cover 5 to wrap the robot. The existing spraying robot adopts four-axis or six-axis rotation, and the requirements for the protective cover 5 are extremely high. If the protective cover 5 is wrapped too tightly, it is easy to wear and tear when rotating horizontally and vertically at the same time. If the wrapping is loose, it is easy to be entangled and stuck in the rotating axis of the robot, which is very inconvenient to use. By setting up the protective cover 5, during installation, the protective cover 5 is put on the extension arm 4 and passes through the extension arm 4, the main arm 3, the rotating seat 2 and the base 1 in sequence, and then the fixing ring 9 wrapped by the protective cover 5 is held, and the fixing ring 9 is put on the surface of the outer movable ring 7. Under the compression of the outer wall of the outer movable ring 7, the block 11 gradually enters the inner side of the slot 13. At this time, the spring 10 is contracted under the force and continues to press down to fix. The fixing ring 9 is used until the fixing ring 9 completely contacts the outer movable ring 7, and the spring 10 pushes the block 11 into the inner side of the limiting groove 12 to complete the first step of fixing, and then the strong magnetic block 15 wrapped by the protective cover 5 is inserted into the inner side of the strong magnetic groove 14. Under the action of the magnetic force, the strong magnetic block 15 is firmly adsorbed on the inner side of the strong magnetic groove 14 to complete the installation; by setting the strong magnetic block 15, the rotating seat 2 and the protective cover 5 are fixed, and the protective cover 5 is fixed to the outer movable ring 7 through the fixing ring 9. There is a ball 8 between the outer movable ring 7 and the inner ring 6, which can rotate freely. When the rotating seat 2 rotates, it can rotate with the protective cover 5, reducing the winding phenomenon caused by rotation in one direction, avoiding the protective cover 5 from being drawn into the rotating shaft during the multi-directional rotation process of the robot, and greatly improving the service life of the protective cover 5.

[0022] In other embodiments, the present embodiment discloses, please Figure 1 and Figure 4 As shown, the top of the rotating seat 2 is rotatably connected to a main arm 3, and one side of the main arm 3 is rotatably connected to an extension arm 4. A fixing groove 16 is provided on the surface of the extension arm 4, and an elastic band 17 is provided inside the fixing groove 16. The surface of the elastic band 17 is fixedly connected to the inner wall of the protective cover 5;

[0023] During installation, slide the elastic band 17 into the inner side of the fixing groove 16, and the elastic band 17 tightens the protective cover 5 to fit tightly with the extension arm 4; by setting the elastic band 17, the elasticity of the elastic band 17 makes the protective cover 5 fit tightly with the extension arm 4, and the extension arm 4 is the component closest to the nozzle. Tightening the protective cover 5 improves the sealing performance, prevents the spraying material from entering the inner side of the extension arm 4, and avoids the spraying material from damaging the robot.

[0024] In other embodiments, the present embodiment discloses, please Figure 1 As shown, there are three elastic bands 17 in total. By setting the elastic bands 17 to three in total, the sealing performance is improved.

[0025] In other embodiments, the present embodiment discloses, please Figure 1As shown, there are two strong magnetic blocks 15, which are symmetrically distributed on both sides of the rotating base 2; by setting the number of strong magnetic blocks 15 to two, which are symmetrically distributed on both sides of the rotating base 2, the protective cover 5 is fixed to improve stability.

[0026] In other embodiments, the present embodiment discloses, please Figure 2 As shown, a first ball groove is provided on the surface of the inner ring 6, and a second ball groove is provided on the inner wall of the outer movable ring 7; by providing the first ball groove on the surface of the inner ring 6 and the second ball groove on the inner wall of the outer movable ring 7, the ball 8 can roll in the ball groove, so that the outer movable ring 7 can rotate freely around the inner ring 6.

[0027] In other embodiments, the present embodiment discloses, please Figure 1 and Figure 2 As shown, there are three blocks 11, which are distributed in a circular shape and equidistantly on the inner side of the fixed ring 9; by setting the number of blocks 11 to three, which are distributed in a circular shape and equidistantly on the inner side of the fixed ring 9, the fixed ring 9 can be stably fixed on the outer surface of the outer movable ring 7.
