Description

Technical Field

[0001] The utility model relates to the technical field of three-axis mechanical arms, in particular to a three-axis mechanical arm with an intelligent sensor device. Background Art

[0002] A three-axis robotic arm is a robotic arm with three degrees of freedom that can move and operate flexibly in three-dimensional space. An intelligent sensor is a device that can sense and obtain environmental information. The two can be used in combination with each other. For example, on an industrial production line, a three-axis robotic arm can be equipped with an intelligent sensor to achieve autonomous operation and collaborative tasks by sensing the environment.

[0003] A Chinese patent discloses a sensor (authorization announcement number CN205482997U), including a box body, a rotary cover structure and an adjusting knob, wherein the adjusting knob is installed in the box body, and the adjusting part of the adjusting knob is exposed outside the box body. The rotary cover structure is installed on the box body and can rotate on the box body, and the adjusting knob can be covered or exposed by changing its position. The rotary cover structure installed on the box body covers the adjusting knob inside the rotary cover structure, so that the adjusting knob is not exposed to the air, and dust or water can be prevented from entering the box body through the adjusting knob to damage the circuit board. When the adjusting knob needs to be adjusted, the rotary cover structure only needs to be rotated to expose the adjusting knob.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when installing sensors on existing three-axis robotic arms, most of them are fixed with screws. When the sensor fails and needs repair, the staff needs to remove the screws to remove the sensor, which is time-consuming and labor-intensive, and affects the work efficiency of the staff. Utility Model Content

[0010] Preferably, the inner diameter of the limiting hole matches the outer diameter of the insertion rod.

[0011] The effect achieved by the above components is: by matching the inner diameter of the limiting hole with the outer diameter of the insertion rod, a stable limit is achieved when the insertion rod is inserted, preventing the insertion rod from loosening and causing the sensor to shake and cause feedback errors, thereby facilitating the stable operation of the sensor housing.

[0012] Preferably, slide grooves are provided on both sides of the mounting rail, a slider is slidably connected inside the slide groove, and one end of the slider close to the traction block is fixedly connected to the traction block.

[0013] The effect achieved by the above components is: through the provision of the slide groove and the slider, a stable limit is achieved when the traction block moves, preventing the traction block from slipping during installation, affecting the installation time of the workers, and facilitating the improvement of work efficiency.

[0016] Preferably, the sensor housing is installed with light-transmitting glass, and the light-transmitting glass is made of glass with a good inner light transmittance.

[0017] The effect achieved by the above components is: by setting the light-transmitting glass, the infrared rays can be emitted unimpeded, preventing the indoor light from affecting the normal operation of the sensor, thus facilitating the normal operation of the sensor.

[0026] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0027] Reference Figure 1 , Figure 2 and Figure 3 As shown, the utility model provides a technical solution: a three-axis robotic arm with an intelligent sensor device, comprising a chassis 1, comprising a chassis 1, the top of the chassis 1 is rotatably connected to a first rotating arm 2, the top of the first rotating arm 2 is rotatably connected to a second rotating arm 3, the front end of the second rotating arm 3 is slidably connected to an extension arm 4, the surface of the top of the extension arm 4 is slidably connected to a sliding plate 5, the top of the sliding plate 5 is fixedly connected to a sensor housing 6, both sides of the extension arm 4 are fixedly connected to connecting plates 7, the inside of the connecting plate 7 is slidably connected to an insertion rod 8, the end of the insertion rod 8 away from the extension arm 4 is fixedly connected to a pulling plate 9, both sides of the sliding plate 5 are provided with limiting holes 11, the top of the extension arm 4 is provided with a mounting rail 12, the inside of the mounting rail 12 is slidably connected to a traction block 13, and the top of the traction block 13 is fixedly connected to the bottom end of the sliding plate 5.

[0028] The following is a detailed description of the specific settings and functions of the sensor quick installation device.

[0029] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in this embodiment: when the staff needs to install the sensor housing 6 on the extending arm 4, the traction block 13 is aligned with the mounting rail 12 and slid into the position of the limiting hole 11, and the pull plate 9 is pushed in to drive the insertion rod 8 to be inserted into the limiting hole 11 to form a limit, thereby achieving rapid installation of the sensor, and the surface of the insertion rod 8 is slidably connected with an elastic spring 10, and the end of the elastic spring 10 close to the connecting plate 7 is fixedly connected to the surface of the connecting plate 7, and the end of the elastic spring 10 away from the connecting plate 7 is fixedly connected to the surface of the pull plate 9. When the staff needs to remove the sensor housing 6, the pull plate 9 is pulled out, and the elastic spring The elastic force stored in 10 is released to make the rod 8 pop out quickly, so that the sensor housing 6 is released from the limit, thereby achieving the rapid disassembly of the sensor housing 6. The inner diameter of the limit hole 11 is matched with the outer diameter of the rod 8. When the staff needs to fix the sensor housing 6, the pull plate 9 is pushed in to drive the rod 8 to be inserted into the limit hole 11. Because the inner diameter of the limit hole 11 is matched with the outer diameter of the rod 8, when the rod 8 is inserted into the limit hole 11, the sensor housing 6 forms a stable limit, thereby achieving the stable limit of the sensor housing 6. Both sides of the mounting rail 12 are provided with a slide groove 14, and the inner sliding connection of the slide groove 14 is The end of the slider 15 close to the traction block 13 is fixedly connected to the surfaces on both sides of the traction block 13. When the staff installs the sensor housing 6, the traction block 13 is slid into the mounting rail 12. Because the end of the slider 15 close to the traction block 13 is fixedly connected to the traction block 13, when the traction block 13 moves, the slider 15 and the slide groove 14 form a stable limit, so as to achieve a stable installation of the sensor housing 6. The front end of the mounting rail 12 is fixedly connected with a buffer spring 16, and the rear end of the buffer spring 16 is fixedly connected to the front end of the buffer plate 17. When the staff slides the sensor housing 6 into the installation, it may be used Excessive force causes the sensor housing 6 to hit the surface of the extended arm 4. At this time, the buffer plate 17 is hit and drives the buffer spring 16 to store force. At the same time, the stored elastic force is offset by the impact force, so that the impact force on the extended arm 4 is reduced, thereby achieving impact protection for the extended arm 4. The sensor housing 6 is installed with a translucent glass 18. The material of the translucent glass 18 is an inner layer of glass with good light transmittance. When the sensor emits infrared sensing, the translucent glass 18 can make the infrared emitted by the sensor emit unimpeded. At the same time, the translucent glass 18 has the function of reflecting most of the indoor light, which can ensure that the sensor is not disturbed by external light and works normally.

[0030] The practical working principle of the present invention is that when the staff needs to install the sensor housing 6 on the extending arm 4, the traction block 13 is aligned with the mounting rail 12 and slid in. When it reaches the position of the limiting hole 11, the pull plate 9 is pushed in to drive the insertion rod 8 to be inserted into the limiting hole 11 to form a limit, thereby achieving rapid installation of the sensor housing 6. When the staff needs to remove the sensor housing 6, the pull plate 9 is pulled out. At this time, the elastic force stored in the elastic spring 10 is released to make the insertion rod 8 pop out quickly, so that the sensor housing 6 is released from the limit, thereby achieving rapid disassembly of the sensor housing 6. When the staff needs to fix the sensor housing 6, the pull plate 9 is pushed in to drive the insertion rod 8 to be inserted into the limiting hole 11. Because the inner diameter of the limiting hole 11 is matched with the outer diameter of the insertion rod 8, when the insertion rod 8 is inserted into the limiting hole 11, the sensor housing 6 forms a stable limit, thereby achieving a stable limit of the sensor housing 6. When the sensor housing 6 is installed, the traction block 13 is slid into the mounting rail 12. Because the end of the slider 15 close to the traction block 13 is fixedly connected to the surfaces on both sides of the traction block 13, the slider 15 and the slide groove 14 form a stable limit when the traction block 13 moves, thereby achieving a stable installation of the sensor housing 6. When the staff slides the sensor housing 6 into the installation, excessive force may be applied, causing the sensor housing 6 to hit the surface of the extension arm 4. At this time, the buffer plate 17 is hit and drives the buffer spring 16 to store force. At the same time, the stored elastic force and the impact force are offset, so that the impact force on the extension arm 4 is reduced, thereby achieving impact protection for the extension arm 4. When the sensor emits infrared sensing, the light-transmitting glass 18 can make the infrared emitted by the sensor emit unimpeded. At the same time, the light-transmitting glass 18 has the function of reflecting most of the indoor light, which can ensure that the sensor is not disturbed by external light and works normally.
