Description

Technical Field

[0001] This utility model relates to the field of clamping mechanism technology, specifically a clamping mechanism for a logistics delivery robot. Background Technology

[0002] The gripper mechanism of a logistics delivery robot is a gripping and fixing device designed specifically for the cargo transportation process. It is a key component for the robot to achieve stable delivery. It consists of a power unit, an adjustment structure and an adapter gripper, providing a reliable guarantee for the stability of the cargo during transportation.

[0003] Existing gripping mechanisms for logistics delivery robots mostly use a single gripping plate to fix goods. This structure has extremely poor adjustability and is difficult to adapt to the delivery of logistics goods in different states, which seriously restricts the robot's ability to adapt to complex logistics gripping. To address this, we propose a gripping mechanism for logistics delivery robots. Utility Model Content

[0004] The purpose of this invention is to provide a gripper mechanism for a logistics delivery robot to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A logistics delivery robot gripper mechanism includes a delivery robot body and a loading platform fixedly connected to the surface of the delivery robot body. A translation mechanism is provided on one side of the top surface of the loading platform, and an adjustment mechanism is provided on the surface of the translation mechanism.

[0007] The translation mechanism includes a limiting box fixedly connected to the top surface of the loading platform. The inner cavity of the limiting box has two mutually spaced wall plates that are rotatably connected to a first bidirectional lead screw. Both ends of the first bidirectional lead screw are threaded with sliding boxes, and sliders are slidably connected in both sliding boxes.

[0008] The adjustment mechanism includes two first L-shaped plates fixedly connected to two sliders respectively. A reinforcing rod is rotatably connected to the side wall of the first L-shaped plate away from the slider. A fixing plate is fixedly connected to the end of the reinforcing rod away from the first L-shaped plate. The upper and lower walls of the fixing plate are provided with a first sliding groove and a second sliding groove. A straight plate and an arc-shaped plate are slidably connected to the inner cavity of the first sliding groove and the second sliding groove respectively.

[0009] Preferably, a mounting base is fixedly connected to the top surface of the bottom plate of the first L-shaped plate, and a third rotating motor is fixedly installed on the top surface of the mounting base. The output end of the third rotating motor passes through the wall plate of the first L-shaped plate and is fixedly connected to one end of the reinforcing rod.

[0010] Preferably, a second bidirectional lead screw and a third bidirectional lead screw are rotatably connected to one side of the fixed plate. The two ends of the second bidirectional lead screw and the third bidirectional lead screw are respectively located in the first sliding groove and the second sliding groove. Two straight plates on the same fixed plate are respectively threaded to two oppositely rotating threads on the second bidirectional lead screw, and the two straight plates are symmetrically arranged about the middle of the second bidirectional lead screw. Two arc-shaped plates on the same fixed plate are respectively threaded to two oppositely rotating threads on the third bidirectional lead screw, and the two arc-shaped plates are symmetrically arranged about the middle of the third bidirectional lead screw.

[0011] Preferably, a second L-shaped plate and a third L-shaped plate are fixedly connected to one side of the top surface of the fixed plate. A fourth rotary motor and a fifth rotary motor are fixedly installed on the second L-shaped plate and the third L-shaped plate, respectively. The output ends of the fourth rotary motor and the fifth rotary motor are fixedly connected to the top ends of the second bidirectional lead screw and the third bidirectional lead screw, respectively.

[0012] Preferably, the translation mechanism further includes a first rotating motor fixedly installed on one side wall of the limiting box, and the output end of the first rotating motor passes through the wall of the limiting box and is fixedly connected to one end of the first bidirectional lead screw.

[0013] Preferably, a second rotating motor is fixedly installed on the top of the sliding box, and a lead screw is fixedly connected to the output end of the second rotating motor through the wall panel of the sliding box. The bottom end of the lead screw is rotatably connected to the bottom surface of the inner cavity of the sliding box, and the slider is threaded onto the lead screw.

[0014] The beneficial effects of this utility model are:

[0015] This invention utilizes a fixed plate, a straight plate, and an arc-shaped plate. The output of a third rotating motor causes the fixed plate to flip, altering its clamping surface. This allows for the clamping and securing of square or cylindrical goods. Activating a fourth and fifth rotating motor, whose outputs drive a second and a third bidirectional lead screw, expands the straight and arc-shaped plates, thereby widening the clamping surface of the fixed plate. This enables the clamping and securing of goods of varying heights, improving the robot's adaptability to complex logistics clamping and enhancing the device's practicality.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4As shown, a logistics delivery robot gripper mechanism includes a delivery robot body 1 and a loading platform 2 fixedly connected to the surface of the delivery robot body 1. A translation mechanism 3 is provided on one side of the top surface of the loading platform 2, and an adjustment mechanism 4 is provided on the surface of the translation mechanism 3. The translation mechanism 3 includes a limiting box 31 fixedly connected to the top surface of the loading platform 2. Two mutually spaced inner walls of the limiting box 31 are rotatably connected to a first bidirectional lead screw 32. Both ends of the first bidirectional lead screw 32 are threaded with sliding boxes 33, and sliders 36 are slidably connected in both sliding boxes 33. The segment mechanism 4 includes two first L-shaped plates 41 respectively fixedly connected to two sliders 36. A reinforcing rod 44 is rotatably connected to the side wall of the first L-shaped plate 41 away from the sliders 36. A fixing plate 45 is fixedly connected to the end of the reinforcing rod 44 away from the first L-shaped plate 41. The upper and lower walls of the fixing plate 45 are each provided with a first sliding groove 46 and a second sliding groove 47. A straight plate 48 and an arc-shaped plate 49 are slidably connected to the inner cavities of the first sliding groove 46 and the second sliding groove 47 respectively. A mounting base 42 is fixedly connected to the top surface of the bottom plate of the first L-shaped plate 41, and a mounting surface is fixedly mounted on the top surface of the mounting base 42. The output end of the third rotating motor 43 passes through the wall of the first L-shaped plate 41 and is fixedly connected to one end of the reinforcing rod 44. A second bidirectional lead screw 401 and a third bidirectional lead screw 404 are rotatably connected to one side of the fixed plate 45. The two ends of the second bidirectional lead screw 401 and the third bidirectional lead screw 404 are respectively located in the first sliding groove 46 and the second sliding groove 47. Two straight plates 48 on the same fixed plate 45 are threadedly connected to the second bidirectional lead screw 401, and the two straight plates 48 are symmetrically arranged about the middle of the second bidirectional lead screw 401. The two arc-shaped plates 49 are threadedly connected to the third bidirectional lead screw 404, and the two arc-shaped plates 49 are symmetrically arranged about the middle of the third bidirectional lead screw 404. The second L-shaped plate 402 and the third L-shaped plate 405 are fixedly connected to one side of the top surface of the fixed plate 45. The fourth rotary motor 403 and the fifth rotary motor 406 are fixedly installed on the bottom surface of the top plate of the second L-shaped plate 402 and the third L-shaped plate 405, respectively. The output ends of the fourth rotary motor 403 and the fifth rotary motor 406 are fixedly connected to the top end of the second bidirectional lead screw 401 and the third bidirectional lead screw 404, respectively.

[0024] In practice, the output of the third rotary motor 43 drives the fixed plate 45 to flip, changing the clamping surface of the fixed plate 45, which can clamp and fix square or cylindrical goods. By starting the fourth rotary motor 403 and the fifth rotary motor 406, the output of the fourth rotary motor 403 and the fifth rotary motor 406 drives the second bidirectional lead screw 401 and the third bidirectional lead screw 404 to rotate, which can drive the straight plate 48 and the arc plate 49 to expand outward, thereby expanding the clamping surface of the fixed plate 45, which can clamp and fix goods of different heights, enhancing the practicality of the device.

[0025] As a technical optimization of this utility model, the translation mechanism 3 also includes a first rotating motor 34 fixedly installed on one side wall of the limiting box 31. The output end of the first rotating motor 34 passes through the wall of the limiting box 31 and is fixedly connected to one end of the first bidirectional lead screw 32. A second rotating motor 37 is fixedly installed on the top of the sliding box 33. The output end of the second rotating motor 37 passes through the wall of the sliding box 33 and is fixedly connected to a lead screw 35. The bottom end of the lead screw 35 is rotatably connected to the bottom surface of the inner cavity of the sliding box 33. The slider 36 is threadedly sleeved on the lead screw 35.

[0026] In practice, the first rotating motor 34 is started, and the output end of the first rotating motor 34 drives the first bidirectional lead screw 32 to rotate. The rotation of the first bidirectional lead screw 32 drives the two sliding boxes 33 to slide, thereby driving the two fixed plates 45 to move closer to each other to clamp and fix the logistics goods.

[0027] By starting the second rotary motor 37, the output end of the second rotary motor 37 drives the lead screw 35 to rotate, thereby driving the slider 36 to rise, which facilitates the lifting of the fixing plate 45 to a specified height to clamp and fix the goods. At the same time, the rise of the slider 36 drives the fixing plate 45 to rise, which facilitates the rotation and conversion of the clamping surface of the fixing plate 45.

[0028] In use, the logistics goods are placed on the loading platform 2. Based on the need for securing the materials, the output of the third rotary motor 43 drives the fixing plate 45 to flip, adjusting the clamping surface of the fixing plate 45 to the designated clamping surface. Then, the output of the fourth rotary motor 403 or the fifth rotary motor 406 drives the second bidirectional lead screw 401 or the third bidirectional lead screw 404 to rotate, expanding the straight plate 48 or the arc-shaped plate 49 outwards. The output of the second rotary motor 37 drives the lead screw 35 to rotate, thereby causing the slider 36 to rise and the fixing plate 45 to rise to the designated height. The output of the first rotary motor 34 drives the first bidirectional lead screw 32 to rotate, causing the two sliding boxes 33 to slide, thus bringing the two fixing plates 45 closer together to clamp and secure the logistics goods. This demonstrates how the delivery robot body 1 can be used to deliver materials.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
