Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1 to 3 , a safety protection door for a production line in an embodiment of the present utility model is arranged between the numerical control equipment 4 and the conveyor line 3, and by using the combined design method of the movable protection door and the fixed protection door 2, when a certain device in the production line fails, the movable protection door can change its position to cut off the connection between the numerical control equipment 4 and the conveyor line 3, thereby preventing the loading and unloading operation of the numerical control equipment 4.

[0029] Specifically, in the safety protection door of the preferred embodiment of the present utility model, it includes a movable protection door and at least two fixed protection doors 2; wherein, the at least two fixed protection doors 2 are arranged at intervals along the X-axis direction, and a conveying channel for workpiece loading and unloading is left between the two fixed protection doors 2; the movable protection door is arranged in this conveying channel, and the movable protection door includes a first door frame 102 and at least one second door frame 103, and the first door frame 102 is arranged between the two fixed protection doors 2; one side of the at least one second door frame 103 is connected to the first door frame 102, and a rotating door 101 is hinged vertically in the second door frame 103, and the size and shape of the rotating door 101 correspond to the size and shape of the conveying channel.

[0030] During the actual use process, if the numerical control device 4 breaks down or the numerical control device 4 is not needed, by adjusting the position of the rotating door 101, the rotating door 101 can close the conveying channel after rotation, and at this time the rotating door 101 is flush with the fixed protection door 2; when the numerical control device 4 is in normal use, the rotating door 101 is arranged at a certain angle with the fixed protection door 2, so that the conveying channel can be loaded and unloaded normally. Preferably, the angle between the rotating door 101 and the fixed protection door 2 is ninety degrees.

[0031] More specifically, as Figure 1 shown, a protection net 108 is arranged at the bottom of the first door frame 102, which is used to close the lower part of the conveying channel, so that when the articulated robot 5 performs loading and unloading operations on the numerical control lathe, it can avoid the pedal of the numerical control device 4 and the movement space of the articulated robot 5 in terms of height, which is convenient for the articulated robot 5 to be linked with the numerical control device 4 for loading and unloading.

So that after adjusting the positions of the two rotating doors 101, they can fit together to close the conveying channel between the numerical control device 4 and the articulated robot 5.

[0033] Of course, during the actual design process, if it is necessary to leave a sufficiently large gap between the numerical control device 4 and the protection door, the width of the rotating door 101 can also be set to be the same as the width of the first door frame 102. At this time, only one rotating door 101 needs to be designed. In the preferred embodiment of the present utility model, an opposed-door design is adopted, so that the width of each rotating door 101 is just enough for one person to pass through, thereby reducing the distance between the numerical control device 4 and the articulated robot 5 and optimizing the overall space layout of the production line.
