In order to ensure the safety of workers on both sides, protective devices such as safety gratings need to be installed on the production line, but the vehicle entering the workstation will trigger the grating, causing the production line to stop; without the grating, the workers may be injured when the vehicle returns to the workstation if they are not careful, and the production safety and personal safety of the workers cannot be guaranteed.
[0003] Therefore, it is necessary to design a safety protection mechanism suitable for the above production scenarios. Summary of the invention

DETAILED DESCRIPTION
[0023] In order to further disclose the content, features and effects of the present invention, the following examples are specifically cited and described in detail in conjunction with the accompanying drawings. In the description of the following embodiments, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing this patent and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this patent.
[0024] In the description of the following embodiments, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "set" should be understood in a broad sense, for example, it can be fixedly connected or set, or it can be detachably connected or set, or connected or set in one piece. For ordinary technicians in this field, the specific meanings of the above terms in this patent can be understood according to specific circumstances.
[0025] Example: See attached Figure 2-3 , a production line personnel safety protection mechanism, including a gantry 4 across both sides of the production line; the gantry 4 is arranged at the entrance side of the operating station 3, and the gantry 4 is provided with a fixed enclosure 5 installed parallel to the production line, and the fixed enclosure 5 is arranged in groups of two, respectively located on both sides of the production line and extending from the column 401 of the gantry 4 to the operating station 3, so as to protect the staff in the station. The gantry 4 also includes a swing door 6 installed perpendicular to the production line; a vehicle monitoring sensor 7 is provided on one side of the gantry 4, and a sensor signal reflection plate 8 is provided at a corresponding position on the other side; a door frame monitoring sensor 9 is installed above the swing door 6, and the door frame monitoring sensor 9 and the vehicle monitoring sensor 7 are both connected to the control system signal of the motion mechanism 2. The vehicle monitoring sensor 7 and the sensor signal reflection plate 8 form a safety grating, and when the vehicle 1 passes by, the grating is blocked to trigger the alarm 12 to alarm. The alarm 12 is fixedly installed at one end of the crossbeam 403 of the gantry 4 to promptly remind the staff of the vehicle's entry.
[0026] Both sides of the upright posts of the door frame 4 are fixed with horizontal mounting rods 402 which are perpendicular to the upright posts 401. The horizontal mounting rods 402 are fixed with vehicle monitoring sensors 7 or sensor signal reflecting plates 8. The horizontal mounting rods 402 are also fixed with the emitting end 901 of the door frame monitoring sensor 9 through a connecting frame. The connecting frame is fixed to the side of the emitting end 901 of the door frame monitoring sensor 9.
[0027] The receiving end 902 of the door frame monitoring sensor 9 is fixed to the top of the swing door 6 through a connecting seat. When the swing door 6 is in a normal position, the receiving end 902 is aligned with the sending end 901 and sends a pass signal to the control system. When the swing door 6 is open, the door frame monitoring sensor 9 recognizes it and sends an emergency stop signal. The vertical rod at the end of the swing door 6 is hinged to the vertical mounting column 11 through a hinge 10. The vertical mounting column 11 and the swing door 6 are both arranged on the side of the column 401 away from the operating station 3. The top surface height of the swing door 6 is lower than the bottom surface height of the vehicle 1. Under normal circumstances, the motion mechanism 2 will not touch the swing door 6 when transporting the vehicle 1.
[0028] Working principle: As the vehicle 1 enters the operating station 2, the four vehicle monitoring sensors 7 arranged along the moving direction of the moving mechanism 2 are triggered in sequence, and the signals disappear in this order after the vehicle 1 passes. When the swing door 6 is in the normal position and triggers the pass signal, the first and second vehicle monitoring sensors 7 are triggered in sequence, and the grating is shielded at this time, allowing the vehicle to pass; when the third and fourth vehicle monitoring sensors 7 are triggered in sequence, the grating is also shielded, and the vehicle 1 can pass smoothly.
[0029] When the swing door 6 is in the open state, it is considered that someone is entering or exiting the operating station 2, the door frame monitoring sensor 9 does not send a pass signal, and the production line stops running immediately.
[0030] The vehicle monitoring sensor 7 and the door frame monitoring sensor 9 are used to judge the state near the operating station 3 and control the motion mechanism 2, which has higher reliability. It adapts to the production equipment while ensuring production safety, has low transformation investment and a wide range of applications.
[0031] Although the preferred embodiments of the utility model are described above, the utility model is not limited to the above specific embodiments, which are merely illustrative and not restrictive. Under the enlightenment of the utility model, ordinary technicians in this field can make many forms without departing from the purpose of the utility model and the scope of protection of the claims. All of these belong to the protection scope of the utility model.
