DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: See Figure 1-4 The utility model provides a technical solution: an industrial robot steering position protection structure, including a bracket 1, a bracket 1, one end of the bracket 1 is connected to a connecting arm 2, one end of the connecting arm 2 is connected to a connecting block 3, one end of the connecting block 3 is connected to a rotating arm 4, a fixing block 10 is arranged on the top of the rotating arm 4, one end of the fixing block 10 is connected to a collar 11, an inner cavity of the collar 11 is sleeved with a CCD detector 12, one end of the CCD detector 12 is connected to a connecting ring 13, one end of the connecting ring 13 is connected to an arc plate 20, one end of the arc plate 20 is provided with a connecting frame 15, one end of the connecting frame 15 is provided with a mounting hole 16, the inner cavity of the mounting hole 16 is provided with a nozzle 17, and one end of the nozzle 17 is connected to a water pipe 18.

[0023] The connecting frame 15 is L-shaped, and the output end of the nozzle 17 is aligned with the detection end of the CCD detector 12 .

[0024] In this embodiment, the CCD detector 12 transmits the captured image to the processing center to avoid possible dangers that may occur when the rotating arm 4 moves, thereby improving the safety of the device.

[0025] When the image transmitted by the CCD detector 12 is blurred, or the detection becomes insensitive after being used for a certain period of time, the water pipe 18 inputs external cleaning liquid into the inner cavity of the nozzle 17, and then the nozzle 17 sprays the cleaning liquid on the lens position of the CCD detector 12, thereby cleaning the dust at the lens of the CCD detector 12 to prevent the dust from affecting the safe use of the device; and the automatic cleaning of dust by the nozzle 17 eliminates the need for manual dust removal by staff, which can improve the convenience of use of the device to a certain extent.

[0026] Reference Figure 4 The nozzle 17 is arranged at an end of the lower part of the connecting frame 15 in an inclined shape. After being arranged in this way, it can be ensured that the nozzle 15 can clean the lens of the CCD detector 12 without affecting the detection line of sight of the CCD detector 12.

[0027] A drainage hole 21 is formed through the bottom center of the arc-shaped plate 20 , and a drainage pipe 22 is provided in the inner cavity of the drainage hole 21 .

[0028] In this embodiment, when the CCD detector is cleaned, the cleaning liquid can be discharged into the drain pipe 22 through the drain hole 21 and then discharged into the external processing equipment through the drain pipe 22 to prevent the cleaning liquid from leaking and causing a difficult-to-process situation.

[0029] Reference Figure 4 The drainage hole 21 is located at the bottom of the arc plate 20, and under the influence of the arc plate 20, the cleaning liquid can flow along the surface of the arc plate 20 to the inner cavity of the drainage hole 21, so that the device can recover the cleaning liquid more completely and quickly.

[0030] A plurality of flow guide tubes 14 are disposed on the inner wall of the connecting ring 13 , an air duct 19 is disposed on the top of the connecting ring 13 , and the output end of the flow guide tube 14 is aligned with the detection end of the CCD detector 12 .

[0031] In this embodiment, after the CCD detector 12 is cleaned, the airflow is input into the air duct 19 through an external air pump, and the airflow is transported to the inner cavity of the guide tube 14 through the air duct 19. After the drainage of the guide tube 14, the airflow can blow on the lens of the CCD detector 12, thereby blowing away the water stains remaining on the surface of the CCD detector 12, so that the CCD detector 12 can quickly resume working condition, thereby making the use of the device more efficient and convenient.

[0032] Among them, installation grooves 5 are opened on both sides of the rotating arm 4, and the inner cavity of the installation groove 5 is provided with multiple telescopic rods 6. One end of the multiple telescopic rods 6 is commonly connected to a protective frame 8. A buffer pad 9 is arranged on the front of the protective frame 8, and the buffer pad 9 is made of rubber plate.

[0033] In this embodiment, when an external object collides with the rotating arm 4, since the protective frame 8 is located on the outside of the rotating arm 4, the collision force of the external object is first borne by the protective frame 8, thereby preventing the rotating arm 4 from being directly damaged, thereby further improving the safety of the device.

[0034] Since the surface of the protection frame 8 is provided with a rubber buffer pad 9 , when an external object contacts the protection frame 8 , the impact force generated will be absorbed by the buffer pad 9 , thereby reducing the impact of the impact force on the stable operation of the rotating arm 4 .

[0035] The outer ring of the telescopic rod 6 is provided with a buffer spring 7 .

[0036] In this embodiment, the buffer spring 7 is used to provide support force for the protective frame 8. When an external object collides with the protective frame 8, the protective frame 8 compresses the buffer spring 7. The buffer spring 7 rebounds under pressure and offsets part of the impact force, thereby further reducing the interference of external factors on the device and improving the stability of the device.
