[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0029] This utility model proposes a dustproof handling robot, as detailed below. Figures 1 to 8 Please provide a detailed explanation.

[0030] A dustproof handling robot includes a robot body 1, a lifting shaft 11 on top of the robot body 1, a tray 2 fixedly mounted on top of the lifting shaft 11, a dustproof net 9 covering the outside of the lifting shaft 11, and multiple first pressure sensors 3 inside the tray 2. A placement plate 4 is fixedly connected to the side of the first pressure sensors 3 away from the tray 2. A longitudinal clamping component 5 and a transverse clamping component 6 are mounted on the placement plate 4. The clamping directions of the longitudinal clamping component 5 and the transverse clamping component 6 are arranged at right angles. The first pressure sensors 3, the longitudinal clamping component 5, and the transverse clamping component 6 are all electrically connected to the same controller.

[0031] This invention uses a first pressure sensor 3 to weigh the transported goods during transportation. By setting up a transverse clamping component 6 and a longitudinal clamping component 5, the goods transported by the robot can be clamped, thereby ensuring stable transportation and stable weighing of the goods during transportation. At the same time, the dustproof net 9 can cover the gap between the pallet 2 and the robot body 1, preventing dust or debris from directly entering the gap and affecting the life of electronic components.

[0032] In some embodiments, the dustproof net 9 includes an outer net cylinder and an inner net cylinder that are nested together and slidably connected. The outer net cylinder is fixedly connected to the surface of the robot body 1 facing the tray 2, and the inner net cylinder is fixedly connected to the tray 2 facing the robot body 1. Both the inner and outer net cylinders are provided with multiple filter holes to isolate dust or other debris in the air from the outside of the gap between the tray 2 and the robot body 1. The separate arrangement of the outer and inner net cylinders can accommodate the lifting shaft 11 driving the tray 2 to move up and down. When the tray 2 moves up and down, the total length of the outer and inner net cylinders will extend or shorten accordingly, thereby achieving isolation and protection of the internal gap during the up and down movement of the tray 2.

[0033] In some embodiments, a sliding groove is provided on the inner sidewall of the outer mesh cylinder along the lifting direction of the lifting shaft 11, and a sliding block is provided on the outer sidewall of the inner mesh cylinder corresponding to the sliding groove. The sliding groove and the sliding block are slidably connected. The slidable connection between the sliding groove and the sliding block enables the outer mesh cylinder and the inner mesh cylinder to slide together, defining the movement trajectory for the relative sliding of the outer mesh cylinder and the inner mesh cylinder, and avoiding frictional losses between the inner and outer mesh cylinders when they rotate.

[0034] In some embodiments, a limiting block is provided at one end of the sliding groove facing the tray 2 to prevent the sliding block from detaching from the sliding groove.

[0035] In some embodiments, the longitudinal clamping unit includes two opposing longitudinal fixing seats 51. Each of the two longitudinal fixing seats 51 has a first clamping plate on one side facing each other. A first telescopic member 53 is provided between the first clamping plate 52 and the longitudinal fixing seats 51, and the first telescopic member 53 is electrically connected to the controller. Under the control of the first telescopic member 53, the two opposing first clamping plates 52 can achieve longitudinal stable clamping of the transported goods. The controller electrically connects the two first telescopic members 53. When the first pressure sensor 3 detects a pressure value, goods are already loaded on the placement plate 4. At this time, after receiving the signal from the first pressure sensor 3, the controller controls the first telescopic member 53 to extend, causing the two first clamping plates 52 to move relative to each other, thereby achieving longitudinal clamping.

[0036] In some embodiments, the lateral clamping unit includes two opposing lateral fixing seats 61. Each of the two lateral fixing seats 61 has a second clamping plate on one side facing each other. A second telescopic member is provided between the second clamping plate 62 and the lateral fixing seats 61, and the second telescopic member is connected to a controller. Through the control of the second telescopic member, the two opposing second clamping plates 62 can achieve lateral stable clamping of the transported goods. The controller electrically connects the two second telescopic members. When the first pressure sensor 3 detects a pressure value, goods are already loaded on the placement plate 4. At this time, after receiving the signal from the first pressure sensor 3, the controller controls the second telescopic member to extend, causing the two second clamping plates 62 to move relative to each other, thereby achieving lateral clamping.

[0037] In some embodiments, the first telescopic member 53 and the second telescopic member have the same structure, both including a micro motor 531. A constant force spring 532, also known as a spring, is fixedly connected to the output shaft of the micro motor 531. A limiting groove 533 for the constant force spring 532 to move is provided on the placement plate 4. The end of the constant force spring 532 is fixedly connected to the first support plate 52 or the second support plate 62. The micro motor 531 is fixedly connected to the longitudinal fixed seat 51 or the transverse fixed seat 61. When the first telescopic member 53 or the second telescopic member needs to extend, the micro motor 531 drives the constant force spring 532 to rotate. The constant force spring 532 moves linearly in the limiting groove 533, and the end of the constant force spring 532 away from the micro motor 531 is fixedly connected to the first support plate 52 or the second support plate 62, thereby driving the first support plate 52 or the second support plate 62 to move linearly, thus completing the support action. When the clamping action needs to be withdrawn, the micro motor 531 will drive the constant force spring 532 to rotate in the opposite direction, performing a winding action on the constant force spring 532. The constant force spring 532 will drive the first clamping plate 52 or the second clamping plate 62 to move linearly along the limiting groove 533, thereby completing the withdrawal action.

[0038] In some embodiments, both the longitudinal fixing seat 51 and the transverse fixing seat 61 are provided with receiving cavities 534, in which the micro motor 531 and the constant force spring 532 are disposed. The receiving cavity 534 can protect the micro motor 531 and the constant force spring 532, and at the same time ensure that the first supporting plate 52 and the longitudinal supporting seat, and the second supporting plate 62 and the transverse fixing seat 61 can fit completely together, providing more placement space for the transported goods.

[0039] In some embodiments, a buffer plate 8 is provided on the first support plate 52 and the second support plate 62 toward the center of the placement plate 4, and a buffer spring 81 is provided between the buffer plate 8 and the first support plate 52 or the second support plate 62. The buffer spring 81 and the buffer plate 8 can protect the goods and prevent damage to some fragile goods when the first support plate 52 and the second support plate 62 act directly on the surface of the goods.

[0040] In some embodiments, a second pressure sensor 521 is provided on one side of the first support plate 52 and the second support plate 62 facing the center of the placement plate 4. The second pressure sensor 521 is electrically connected to the controller. When the second pressure sensor 521 detects pressure, it indicates that the goods have come into contact. A threshold can be set for the second pressure sensor 521 in the controller. When the pressure value detected by the second pressure sensor 521 reaches the threshold, the second pressure sensor 521 sends a stop support signal to the controller. The controller then controls the first telescopic member 53 or the second telescopic member to stop its extension action, thereby preventing the pressure from continuously increasing and causing pressure damage to the goods.

[0041] In some embodiments, a buffer plate 8 and a buffer spring 81 are provided in front of the first support plate 52 or the second support plate 62, and a second pressure sensor 521 is also provided on the first support plate 52 or the second support plate 62. In this case, the buffer spring 81 is placed between the second pressure sensor 521 and the buffer plate 8. When the buffer spring 81 is compressed, the buffer spring 81 will apply elastic force to the second pressure sensor 521. At this time, the second pressure sensor 521 can work normally and is used to detect the support pressure on the goods.

[0042] In some embodiments, a plurality of first pressure sensors 3 are arranged in an array above the pallet 2. The array arrangement of the plurality of first pressure sensors 3 can perform balanced positive pressure measurement of the goods, thereby avoiding inaccurate pressure measurement due to uneven gravity distribution.

[0043] In some embodiments, a display screen 7 is provided on the side wall of the pallet 2, and the display screen 7 is electrically connected to the controller. The display screen 7 is configured to clearly display the total weight of the goods being transported at this time.
