[0039] Please refer to Figures 1 to 9 A logistics robot, including base 1, the front end of the lower surface of base 1 is provided with steering wheel 2, the middle of one side of the top of base 1 is rotatably connected with hydraulic rod 3, the outer surface of hydraulic rod 3 is provided with first gear 5, the output end of hydraulic rod 3 is fixedly connected with electric slide rail 7, one side of the top of base 1 is fixedly connected with drive motor 4, the output end of drive motor 4 is fixedly connected with second gear 6, the outer surface of electric slide rail 7 is slidably connected with clamping assembly 8.

[0040] As Figure 2 shown, clamping assembly 8 includes sliding frame 81 sliding on the outer surface of electric slide rail 7, the bottom of sliding frame 81 is fixedly connected with mounting plate 89, the inside of mounting plate 89 is provided with slot 86, the top of sliding frame 81 is fixedly connected with servo motor 810, the output end of servo motor 810 is fixedly connected with crown gear 82, both sides of sliding frame 81 are rotatably connected with first threaded rod 84, the outer surface of first threaded rod 84 is threadedly connected with clamping plate 85, one side of two first threaded rods 84 close to each other is fixedly connected with third gear 83, one side of clamping plate 85 is provided with dust removal assembly 87 for removing dust from the opposite surface of clamping plate 85.

[0041] One side of first threaded rod 84 extends to the inside of sliding frame 81, third gear 83 is located below crown gear 82, third gear 83 and crown gear 82 are engaged with each other, both sides of clamping plate 85 are recessed, clamping plate 85 slides in the inside of slot 86, one side of two clamping plates 85 close to each other is provided with anti-skid pad, the middle of the bottom of mounting plate 89 is provided with auxiliary adsorption assembly 88.

[0042] When the logistics robot grabs the package, drive motor 4 drives second gear 6 to rotate, second gear 6 drives hydraulic rod 3 to rotate in all directions through first gear 5, so that the package in any area can be grabbed, electric slide rail 7 can control linear movement of sliding frame 81, the package in the area swept by the rotation of electric slide rail 7 can be grabbed, when grabbing, sliding frame 81 is driven to the upper side of the package by electric slide rail 7, sliding frame 81 is driven to move downward by hydraulic rod 3, two clamping plates 85 are moved to the two sides of the package, at this time, crown gear 82 is driven to rotate by servo motor 810, first threaded rod 84 is driven to rotate by two crown gears 82, first threaded rod 84 drives clamping plate 85 to slide in slot 86, so that two clamping plates 85 approach the package and clamp, then the package is transported to the upper side of base 1 for stacking by the cooperation of electric slide rail 7 and hydraulic rod 3, so that the problem that the logistics robot in the prior art can only transport and transfer single can be solved, the functionality of the robot is improved, the labor of the staff carrying the package can be greatly reduced, and the efficiency of logistics work is greatly improved.

[0043] like Figures 3-5 As shown, the cleaning component 87 includes an air pump 871 fixed on one side of the clamping plate 85 and an L-shaped plate 874 fixed at the edge of one side of the clamping plate 85. The output end of the air pump 871 is fixedly connected to a rubber hose 872, one side of the L-shaped plate 874 is fixedly connected to a first spring 875, one side of the first spring 875 is fixedly connected to a guide frame 873, and one side of the guide frame 873 is provided with an air outlet 876.

[0044] One side of the rubber hose 872 is fixedly connected to the guide frame 873 , the interior of the rubber hose 872 is connected to the interior of the guide frame 873 , and the opening of the air outlet 876 is directed toward the clamping plate 85 .

[0045] The inner bottom of the guide frame 873 is fixedly connected to the guide plate 877, and the top of the guide plate 877 is fixedly connected to the inner top of the guide frame 873. The cross-sections of the guide frame 873 and the guide plate 877 are in the shape of a U-shaped arrow.

[0046] However, during long-term use, the clamping plate 85 will adhere to a large amount of dust due to the presence of dust and stains on the wrapped surface. The increased dust will reduce the friction of the clamping plate 85, causing the clamping plate 85 to slip when clamping an object. Therefore, each time the clamping plate 85 clamps an object, the air pump 871 is started in advance to convey air to the inside of the guide frame 873 through the rubber hose 872. The air enters the inside of the guide frame 873 and is guided by the guide plate 877 and ejected from the inside of the air outlet 876. The air ejected from the air outlet 876 cleans the dust on the surface of the clamping plate 85, thereby avoiding the reduction of friction caused by excessive dust on one side of the clamping plate 85 and improving the clamping stability of the clamping plate 85.

[0047] During clamping, the guide frame 873 first contacts the object. Driven by the reaction force, the guide frame 873 moves to one side of the clamping plate 85 and compresses the first spring 875 until the clamping plate 85 contacts the package. This ensures that the guide frame 873 does not hinder the normal operation of the clamping plate 85 during operation. However, when the clamping plate 85 drops the package, the guide frame 873 loses its compression of the package and returns to its original position under the action of the two first springs 875, ready for the next operation.

[0048] like Figure 6 As shown, the auxiliary adsorption assembly 88 includes three second springs 882 fixed to the bottom of the mounting plate 89 , the bottoms of the three second springs 882 are fixedly connected to a connecting plate 881 , and the bottom of the connecting plate 881 is fixedly connected to an electric suction cup 883 .

[0049] When the package is clamped, if the package is too heavy and the clamping force of the clamping plate 85 is insufficient, it is possible to cause the package to fall and easily cause the package to fall, causing the objects inside the package to be damaged. Therefore, when the clamping plate 85 moves downward to the two sides of the package, the electric suction cup 883 is in contact with the top of the package, and the mounting plate 89 continues to move downward, compressing the second spring 882, and the second spring 882 provides a pressing force for the electric suction cup 883. At this time, the electric suction cup 883 is powered on to adsorb the package, so as to improve the stability of the clamping plate 85 clamping the package, greatly prevent the package from falling, improve the upper limit of the weight of the object carried by the robot, and greatly improve the safety of the robot.

[0050] As shown in Figures 7-8 The base 1 upper surface two side edges are provided with a switching assembly 9, the switching assembly 9 includes a fixed seat 91 fixed on both sides of the top of the base 1 and a jacking assembly 98 fixed on one end of the base 1, one side of the fixed seat 91 is rotatably connected with a rotating plate 92, one side of the rotating plate 92 is provided with a rubber drive wheel 93 and a hard drive wheel 94 respectively, and two insertion holes 95 are formed in the inside of the rotating plate 92. The inside of the fixed seat 91 is slidably connected with an insertion rod 96, and the outer surface of the insertion rod 96 is sleeved with a third spring 97.

[0051] The outer surface of the insertion rod 96 is provided with a limiting ring, and the third spring 97 is located between the fixed seat 91 and the limiting ring. The insertion rod 96 and the insertion hole 95 are matched with each other.

[0052] When the robot works, the ground of its working environment may encounter a relatively smooth ground and may encounter a rough cement ground. The selection of wheels is very important in different areas. Improper selection may cause the robot to slip on smooth ground or cause accelerated wear of the wheels on the cement ground. When on smooth ground, the rubber drive wheel 93 needs to be rotated, and when on cement ground, the hard drive wheel 94 needs to be selected. When switching, the insertion rod 96 is pulled out from the inside of the insertion hole 95, the rotating plate 92 is rotated to exchange the rubber drive wheel 93 and the hard drive wheel 94, and then the insertion rod 96 is inserted into the inside of the insertion hole 95 to fix the rotating plate 92. Thus, the adaptability of the robot can be improved, the robot can be prevented from slipping on smooth ground when using the hard drive wheel 94, and the surface of the rubber drive wheel 93 can be prevented from being worn when used on the cement ground.

[0053] As shown in Figure 9 The jacking assembly 98 includes a side plate 981 fixed on one end of the base 1, an inner threaded rod 986 rotatably connected in the inside of the side plate 981, a second threaded rod 982 threadedly connected in the inside of the inner threaded rod 986, a supporting plate 987 fixedly connected to the bottom of the second threaded rod 982, a handle 983 rotatably connected to the top of the side plate 981, a drive gear 984 fixedly connected to the outer surface of the handle 983, and a driven gear 985 fixedly connected to the outer surface of the inner threaded rod 986.

[0054] The drive gear 984 is located between two driven gears 985, and the drive gear 984 is in mesh with the driven gears 985.

[0055] But when switching the rubber drive wheel 93 and the hard drive wheel 94, it is necessary to manually lift one end of the logistics robot for replacement, which is inconvenient in operation. Therefore, the handle 983 is rotated to drive the drive gear 984 to rotate, the drive gear 984 drives the inner threaded rod 986 to rotate through the driven gears 985, and the second threaded rod 982 is driven to move downward through the threaded action, the supporting plate 987 is in contact with the ground, and one end of the base 1 is lifted to make the hard drive wheel 94 or the rubber drive wheel 93 suspended, so that the switching can be quickly performed.

[0056] Method for use: when the logistics robot grabs the package, the air pump 871 is started, and the air flow is sent to the inside of the flow guide frame 873 through the rubber hose 872, the air flow enters the inside of the flow guide frame 873 and is sprayed from the inside of the air outlet 876 through the guide of the flow guide plate 877, and the air flow sprayed from the air outlet 876 cleans the surface dust of the clamping plate 85;

[0057] The second gear 6 is driven to rotate by the driving motor 4, the first gear 5 drives the hydraulic rod 3 to rotate in all directions, and any area of the package can be grabbed. The electric sliding rail 7 can control the linear movement of the sliding frame 81, and the package in the area swept by the rotation of the electric sliding rail 7 can be grabbed. When grabbing, the sliding frame 81 is driven to the upper side of the package by the electric sliding rail 7, the sliding frame 81 is driven to move downward by the hydraulic rod 3, and the two clamping plates 85 are moved to the two sides of the package. At this time, the crown gear 82 is driven to rotate by the servo motor 810, the first threaded rod 84 is driven to rotate by the two crown gears 82, the clamping plate 85 is driven to slide in the slot 86, so that the two clamping plates 85 are close to the package and clamped, and then the package is transported to the upper side of the base 1 by the cooperation of the electric sliding rail 7 and the hydraulic rod 3;

[0058] When grabbing, the electric suction cup 883 is in contact with the top of the package, the mounting plate 89 continues to move downward, the second spring 882 is compressed, and the second spring 882 provides extrusion force for the electric suction cup 883. At this time, the electric suction cup 883 is electrified to adsorb the package, so as to improve the stability of the clamping plate 85 clamping the package;

[0059] Rotating the rotating handle 983 drives the driving gear 984 to rotate, the driving gear 984 drives the inner threaded rod 986 to rotate through the driven gear 985, and the second threaded rod 982 is driven to move downward through the threaded action, the supporting plate 987 is in contact with the ground, and one end of the base 1 is lifted to make the hard driving wheel 94 or the rubber driving wheel 93 suspended, the inserting rod 96 is pulled out from the inside of the insertion hole 95, the rotating plate 92 is rotated to exchange the rubber driving wheel 93 and the hard driving wheel 94, the inserting rod 96 is inserted into the inside of the insertion hole 95 to complete the fixation of the rotating plate 92, and the appropriate rubber driving wheel 93 and hard driving wheel 94 are selected according to different ground.
