Description

Technical Field

[0001] This utility model relates to the field of detection device technology, specifically a robot collision detection device. Background Technology

[0002] Currently, transportation robots are being used more and more widely in logistics, warehousing and automated production. These robots are usually responsible for automatically navigating and transporting goods in specific areas, which greatly improves work efficiency. However, as the working environment of transportation robots becomes more complex, such as the increase in personnel flow and obstacles, the risk of collisions between robots and other objects or people also increases.

[0003] The authorized publication number "CN222308913U" describes "a robot collision detection device, comprising: a support assembly, which includes a base and two columns symmetrically arranged on the base, forming a sliding gap between the two columns; a detection assembly, which includes a slide table, a detection column, and a pressure plate, wherein the slide table is slidably disposed on the columns and located within the sliding gap, the detection column is a columnar structure, one end of the detection column is connected to the slide table, and the pressure plate is disposed at the other end of the detection column; and a buffer assembly, which includes a first spring and an infrared ranging head, wherein the first spring is sleeved on the detection column, and both ends of the first spring are respectively connected to the pressure plate and the slide table, and the infrared ranging head is disposed on the slide table and aligned with the pressure plate. This robot collision detection device can effectively acquire the collision force of the robot at various operating speeds, facilitating the setting of the operating speed at the factory and improving the safety of the robot during operation."

[0004] The aforementioned patent can effectively obtain the collision force of the robot at various operating speeds, which facilitates the setting of the operating rate at the factory and improves the safety of the robot during operation. However, the robot collision detection device has a single detection direction. During the experimental testing process, if the robot collision angle is incorrect, it is easy to cause uneven force distribution, thereby affecting the detection data. Utility Model Content

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please see Figure 1-3 This utility model provides a technical solution: a robot collision detection device, comprising:

[0023] Fixed column 1;

[0024] The collision structure is located inside the fixed column 1;

[0025] The collision structure includes a lifting rod 2, a collision frame 3, a compression ring plate 4, a lower fixing plate 5, an upper fixing plate 6, two fixing frames 7, and an inflatable rubber 8. The lower surface of the outer wall of the lifting rod 2 is slidably embedded in the fixing column 1. The inner wall of the lower fixing plate 5 is fixedly sleeved on the lifting rod 2. The bottom of the outer wall of the upper fixing plate 6 is fixedly sleeved on the lifting rod 2. The two fixing frames 7 are respectively fixed on the lower fixing plate 5 and the upper fixing plate 6 on opposite sides. The outer wall of the inflatable rubber 8 is embedded between the two fixing frames 7 and the lifting rod 2. The outer wall of the compression ring plate 4 is slidably embedded between the two fixing frames 7. The inner wall of the collision frame 3 is fixedly sleeved on the compression ring plate 4.

[0026] In this implementation scheme: the lifting rod 2 can be moved up and down stably by the fixed column 1. The lower fixed plate 5 and the upper fixed plate 6 are fixed on the lifting rod 2, so that the two fixed frames 7 are fixed. At the same time, the extrusion ring plate 4 can move between the two fixed frames 7. After the collision frame 3 receives the robot's collision, it will push the extrusion ring plate 4 to slide between the two fixed frames 7, thereby extruding it on the inflatable rubber 8 between the two fixed frames 7, so that the inflatable rubber 8 is compressed, thereby changing the air pressure inside the inflatable rubber 8.

[0027] Specifically, a pressure detector 9 is fixedly fitted onto the upper surface of the outer wall of the lifting rod 2.

[0028] In this embodiment, the pressure detector 9 can detect changes in the internal air pressure of the inflatable rubber 8, thereby calculating the impact force.

[0029] Specifically, a support plate 10 is fixedly provided at the bottom of the outer wall of the fixed column 1, and multiple mounting holes are provided at equal intervals along the circumferential surface of the outer wall of the support plate 10.

[0030] In this embodiment, the support plate 10 can stably support the fixed column 1, and multiple mounting holes are used for fixing.

[0031] Specifically, a control motor 11 is fixedly installed on the top of the outer wall of the support plate 10, and the outer wall of the control motor 11 is embedded in the fixed column 1.

[0032] In this embodiment: when the motor 11 is powered on, its output end can drive the threaded rod 12 to rotate.

[0033] Specifically, the output end of the control motor 11 is fixedly provided with a threaded rod 12, and the outer wall of the threaded rod 12 is threaded and embedded in the lifting rod 2.

[0034] In this embodiment, the threaded rod 12 will be threaded into the lifting rod 2 during rotation, thereby controlling the up and down movement of the lifting rod 2.

[0035] Specifically, the outer wall of the collision frame 3 is fixedly fitted with a collision soft sleeve 13.

[0036] In this embodiment, the collision soft sleeve 13 can prevent the robot from directly contacting the collision frame 3, thus protecting the robot and the collision frame 3.

[0037] In use, the support plate 10 can stably support the fixed column 1 and fix it with multiple mounting holes. The fixed column 1 can stably move the lifting rod 2 up and down. The lower fixed plate 5 and the upper fixed plate 6 are fixed on the lifting rod 2, fixing the two fixed frames 7. At the same time, the extrusion ring plate 4 can move between the two fixed frames 7. After the collision frame 3 receives the robot's collision, it will push the extrusion ring plate 4 to slide between the two fixed frames 7, thereby extruding it onto the inflatable rubber 8 between the two fixed frames 7, causing the inflatable rubber 8 to be compressed, thereby changing the air pressure inside the inflatable rubber 8. The pressure detector 9 can detect the change in the air pressure inside the inflatable rubber 8, thereby calculating the collision force. When the control motor 11 is powered on, the output end can drive the threaded rod 12 to rotate. During the rotation, the threaded rod 12 will be threaded into the lifting rod 2, thereby controlling the up and down movement of the lifting rod 2, thereby changing the collision height.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
