[0020] 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.

[0021] See also Figure 1-4 In this embodiment, a peripheral device anti-collision alarm protection device includes a mounting plate 1, a protection mechanism 2 and a master control system. The master control system includes a distance sensor, a controller, a dual-axis motor 202 and an alarm.

[0022] The distance sensor, controller, dual-axis motor 202 and alarm are electrically connected. The distance sensor is used to detect the distance between the robot and the peripheral equipment and provide distance information to the controller. The controller receives the signal from the sensor to trigger the protection mechanism 2 and the alarm to protect the robot from collision with the mounting plate 1. When a collision occurs, the alarm will also be triggered, thereby achieving the effect of anti-collision and alarm.

[0023] The protection mechanism 2 includes a accommodating cavity 201. The accommodating cavity 201 is opened inside the mounting plate 1. A dual-axis motor 202 is fixedly installed inside the accommodating cavity 201. Screw rods 203 are fixedly installed at the two output shafts of the dual-axis motor 202. The outer surfaces of the two screw rods 203 are threadedly connected with sleeves 204. Moving plates 205 are fixedly installed at the opposite ends of the two sleeves 204. Moving rods 206 are arranged on the opposite sides of the two moving plates 205. Pistons 207 are fixedly installed on the opposite ends of the two moving rods 206. Air cylinders 208 are arranged on the outer surfaces of the two pistons 207. An air inlet box 209 is fixedly installed between the opposite sides of the two air cylinders 208. An air bag 210 is arranged on the front side of the mounting plate 1.

[0024] Two slide grooves are provided on the inner top wall of the accommodating chamber 201, and sliders are fixedly installed on the tops of the two movable plates 205. The two sliders are slidably connected to the slide grooves. By setting the slide grooves and sliders, the stability of the two movable plates 205 during movement is improved, thereby driving the movable rod 206 and the piston 207 to move smoothly left and right.

[0025] Two support columns are fixedly mounted on the inner bottom wall of the accommodating chamber 201 . The support columns are provided to facilitate stable support of the two gas cylinders 208 .

[0026] The diameters of the two pistons 207 are equal to the inner diameter of the air cylinder 208 , and the two pistons 207 are slidably connected to the inner wall of the air cylinder 208 . The two pistons 207 are driven by two movable rods 206 to move relative to each other in the air cylinder 208 , so that the air pressure can be squeezed into the air inlet box 209 .

[0027] Mounting holes are provided at the four corners of the mounting plate 1, an opening is provided on the front side of the mounting plate 1, the front side of the air inlet box 209 passes through the opening and extends to the outside of the mounting plate 1, an air outlet is provided on the front side of the air inlet box 209, and a sealing plug is provided on the air outlet.

[0028] By providing the opening, the air inlet box 209 is exposed to the outside of the accommodating cavity 201 , thereby facilitating opening the sealing plug and allowing external gas to enter the air inlet box 209 .

[0029] Inlet pipes are provided between the two ends of the front side of the air intake box 209 and the airbag 210. Through the connection between the two air intake pipes and the airbag 210, the air pressure in the air intake box 209 can be squeezed into the airbag 210 to expand the airbag 210, forming an anti-collision protection barrier between the robot and the mounting plate 1.

[0030] The four corners of the mounting plate 1 are provided with mounting holes. By providing the mounting holes, it is convenient to install and fix the mounting plate 1 on the peripheral equipment to be protected, and connect the device with the peripheral equipment to perform anti-collision alarm protection.

[0031] When implementing, follow these steps:

[0032] 1) First, install and fix the device together with the peripheral equipment to be protected through the four mounting holes on the mounting plate 1;

[0033] 2) Then when the machine collides with the mounting plate 1, the distance sensor detects this signal and provides the signal to the controller, which starts the dual-axis motor 202 and the alarm;

[0034] 3) The dual-axis motor 202 drives the two screw rods 203 to rotate, the two screw rods 203 drive the two sleeves 204 to move left and right, the two sleeves 204 drive the two moving plates 205 to move left and right stably in the slide groove through the top slider, the two moving plates 205 drive the two moving rods 206 to move left and right, and the two moving rods 206 drive the two pistons 207 to move left and right in the air cylinder 208;

[0035] 4) Finally, the generated air pressure is squeezed into the air inlet box 209, and the air pressure in the air inlet box 209 enters the airbag 210 through two air inlet pipes, so that the airbag 210 expands, protecting the robot from collision with the mounting plate 1, and the alarm sounds an alarm.

[0036] To sum up, in the peripheral equipment anti-collision alarm protection device, when the robot collides with the mounting plate 1, the protection mechanism 2 is automatically started, which can make the dual-axis motor 202 enter the operating state, drive the two movable rods 206 and the piston 207 to move back and forth left and right, squeeze the gas into the air inlet box 209, and input the gas into the air bag 210 through the air inlet pipe, so that the air bag 210 expands, and a buffer layer is formed between the robot and the mounting plate 1, so as to protect the robot from collision with the mounting plate 1. When a collision occurs, the alarm will also be triggered, thereby achieving the effect of anti-collision and alarm.
