At this time, the camera needs to be physically protected from collision, and the lens needs to be isolated from foreign objects attached to the air.

[0003] Most of the existing industrial camera protection devices have no self-locking function at all; most of the existing industrial camera protection devices with self-locking function adopt a three-point self-locking structure, which has a poor self-locking effect and can easily cause one side to fail to lock, resulting in contamination of the camera lens;

[0004] The existing self-locking protection device of industrial cameras adopts a card slot type pull-out end cover, which is not tightly sealed, gaseous foreign matter can enter the camera cavity, and the friction pull-out life is short;

[0005] The existing industrial cameras use flip-cover protection that easily blocks the camera's field of view and is not tightly sealed. When the camera moves with the robot, condensate will flow back and contaminate the camera. Summary of the invention

[0006] The present invention aims to at least solve the technical problems of the protective device having a loose structure and a short service life in the prior art.

[0049] The lower part of the housing 100 is provided with an opening for the industrial camera to collect images, and an end cover opening and closing motion unit is provided below the opening;

[0050] The end cover opening and closing motion unit includes a driving device 200, a slider connecting rod mechanism 300 connected to the output end of the driving device, and an end cover 400 connected to the slider connecting rod mechanism 300 and close to the opening side;

[0051] A limiting block 600 is provided on one side of the opening away from the extending direction of the driving device 200;

[0052] A sealing strip 401 is disposed on one side of the end cover 400 close to the opening.

[0053] like Figure 1 , Figure 2 and Figure 3As shown, the driving device 200 moves laterally and drives the end cover 400 to move toward the opening in a direction parallel to the opening through the slider-link mechanism 300, and then the end cover 400 interferes with the limit block 600. Due to the interference and limiting effect of the limit block 600, when the driving device 200 drives the slider-link mechanism 300 to continue to move laterally, the end cover 400 stops moving laterally, and the end cover 400 moves toward the opening in a direction perpendicular to the opening under the support force of the connecting rod 302 of the slider-link mechanism 300, so that the end cover 400 moves upward toward the opening to achieve self-locking.

[0054] When the opening needs to be opened, the output shaft of the driving device 200 drives the slider linkage 300 to move laterally away from the opening, and the end cover 400 moves away from the opening in a direction perpendicular to the opening, and then the end cover 400 is freed from the restriction of the limit block 600 and returns to the initial state and initial position driven by the driving device 200. Figure 1 shown.

[0055] The self-locking protection device of the present invention adopts a two-point self-locking support, the support surface has no lever mechanism, the self-locking pressure is uniform, the end cover 400 is sealed consistently on all sides, there is no sealing protection dead point, the camera space is effectively sealed, and a closed environment is formed during non-photographing, which can achieve the isolation of industrial cameras from foreign objects in the three states of gas, liquid, and solid, and ensure the accuracy of photo recognition. The shell 100 can achieve collision protection for industrial cameras; after the end cover 400 interferes with the limit block 600, the end cover 400 moves along the axial direction of the camera, and the end cover 400 and the opening edge of the shell 100 are pressed in a pressure-touch manner, without obvious sliding friction, less wear on the sealing strip, better sealing effect, and longer service life.

[0061] A sealing strip 401 is disposed on one side of the end cover 400 close to the opening.

[0062] like Figure 1 , Figure 2 and Figure 3 As shown, the driving device 200 moves laterally and drives the end cover 400 to move toward the opening in a direction parallel to the opening through the slider-link mechanism 300, and then the end cover 400 interferes with the limit block 600. Due to the interference and limiting effect of the limit block 600, when the driving device 200 drives the slider-link mechanism 300 to continue to move laterally, the end cover 400 stops moving laterally, and the end cover 400 moves toward the opening in a direction perpendicular to the opening under the support force of the connecting rod 302 of the slider-link mechanism 300, so that the end cover 400 moves upward toward the opening to achieve self-locking.

[0063] When the opening needs to be opened, the output shaft of the driving device 200 drives the slider linkage 300 to move laterally away from the opening, and the end cover 400 moves away from the opening in a direction perpendicular to the opening, and then the end cover 400 is freed from the restriction of the limit block 600 and returns to the initial state and initial position driven by the driving device 200.
