Description

Technical Field

[0001] The utility model relates to the technical field of tire production, in particular to a tire contact detection device for a robot. Background Art

[0002] At present, the tire contactor of the tire unloading arm of the Huagong Baichuan vulcanizer used in the factory production is in the form of an articulated paddle. The tire contact paddle is designed to be too long and has poor rigidity. When vulcanizing small-sized tires, the tire contact stroke of the paddle is short and cannot drive the armature at the root of the paddle to be effectively detected by the detection photoelectric detection, resulting in the robot arm having no tire grabbing signal and being unable to realize the tire grabbing action;

[0003] In addition, since the paddle is long, long-term tilted arrangement will cause deformation and affect the detection sensitivity. If the paddle is shortened, it will be impossible to identify because of the small rotation angle after touching the tire. Therefore, the inventor wants to replace the structure of the tire touching device. Summary of the invention

[0004] The purpose of the utility model is to provide a tire touch detection device for a robot arm in view of the defects in the prior art, which has the advantages of compact structure, short stroke and stable and reliable detection.

[0005] The technical solution of the utility model is: a tire contact detection device for a robot, comprising an inverted L-shaped bracket, wherein a vertical sliding sleeve is provided at a longitudinal end of the inverted L-shaped bracket;

[0006] A slider is slidably connected in the sliding sleeve, a vertical sliding groove is provided on the top of the sliding sleeve, a limit pin is slidably connected in the sliding groove, and the limit pin is connected to the slider;

[0007] A horizontally arranged proximity switch is provided on one side of the sliding sleeve, a tire contact plate is provided at the bottom of the sliding block, and a vertical plate matched with the detection end face of the proximity switch is provided at the upper end of the tire contact plate.

[0008] Preferably, a mounting plate is provided on one side of the sliding sleeve, an assembly hole is provided on the mounting plate, and the proximity switch is mounted on the assembly hole.

[0009] Preferably, a bolt mounting hole is provided at the lateral end of the inverted L-shaped bracket.

[0010] Preferably, the vertical plate and the tire contact plate are integrally formed.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] The utility model has a simple and reasonable structure, and realizes the capture of position signals through vertical sliding and the cooperation of the vertical plate and the proximity switch. It has the advantages of compact structure, short stroke and stable and reliable detection, and especially solves the problem of small turning angle and low sensitivity caused by the current structure using swinging paddles.

[0017] The utility model is further described below with reference to the accompanying drawings and embodiments. Example 1

[0018] As shown in Figures 1 to 3, a tire contact detection device for a robot includes an inverted L-shaped bracket 1. The inverted L-shaped bracket 1 is divided into a transverse end and a longitudinal end. The transverse end of the inverted L-shaped bracket 1 is provided with a bolt installation hole 9.

[0019] A vertical sliding sleeve 2 is provided at the longitudinal end of the inverted L-shaped bracket 1, and a sliding block 3 is slidably connected inside the sliding sleeve 2.

[0020] A vertical slide groove 10 is provided on the top of the sliding sleeve 2 , and a limit pin 4 is slidably connected in the slide groove 10 , and the limit pin 4 is connected to the sliding block 3 .

[0021] A mounting plate 5 is provided on one side of the sliding sleeve 2. An assembly hole 11 is provided on the mounting plate 5. A horizontally arranged proximity switch 6 is installed on the assembly hole 11.

[0022] A tire contact plate 8 is provided at the bottom of the slider 3, and a vertical plate 7 is provided at the upper end of the tire contact plate 8 to match the detection end face of the proximity switch 6. The vertical plate 7 and the tire contact plate 8 adopt an integrally formed structure, and the structural strength is stronger.

[0023] When in use, the device is hoisted on the frame through the bolt mounting holes 9. When the tire rises, the tire contact plate 8 is pushed up, and the vertical plate 7 on the tire contact plate 8 rises accordingly. When the vertical plate 7 blocks the detection end face of the proximity switch 6, the position signal is recognized.

[0024] The utility model has a simple and reasonable structure, realizes the recognition of position signals by means of vertical sliding and the cooperation of the vertical plate 7 and the proximity switch 6, has the advantages of compact structure, short stroke and stable and reliable detection, and especially solves the problems of small turning angle and low sensitivity caused by the current structure using the swinging paddle.

[0025] The present invention is not limited to the above-mentioned implementation modes. Within the knowledge scope of those skilled in the art, various changes can be made without departing from the purpose of the present invention. The changed contents still belong to the protection scope of the present invention.
