[0002] Truckless carriers are a new type of logistics and transportation organization model. They do not own vehicles, but instead integrate social resources to provide full-process logistics and transportation services from the starting point to the destination. Truckless carriers organize cargo sources and manage transportation through platforms, using Internet technology to improve logistics and transportation efficiency.

[0003] During the collection and distribution process, the goods waiting to be transported need to be transported to storage racks in different locations. However, due to the complex types of goods and the different sizes of goods, the existing cargo transport robots can only collect and transport goods of a single size, but are difficult to adapt to objects of different sizes. Moreover, the existing cargo transport robots can only transport goods to a designated ground, and subsequently need to use manual labor or other equipment to transfer the transported goods to the designated shelves, which greatly increases the process of cargo transportation.

The slide passes through the rotating plate and is slidably arranged with the rotating plate, and a second proximity switch is installed through the inside of the rotating plate and the slide in a horizontal position.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. When the item is placed on the carrier plate, the first motor rotates forward. Due to the first spring and the teeth on the grooved wheel, it will not drive the transmission gear to rotate. The first motor will only drive the first worm to rotate, and the first worm will drive the first worm wheel to rotate. The first worm wheel will drive the rotating gear to rotate through the connecting rod, and the rotating gear will drive the inner gear ring to rotate, thereby driving the carrier plate to rotate.

[0021] 2. The carrying plate rotates on the inner wall of the outer gear plate and the rotating ring, and the outer gear plate, the rotating ring and the surface of the robot base do not rotate. The top side of the connecting arm rotates inside the limiting groove through the slider. The rotation of the carrying plate will drive the protective box fixedly connected to the carrying plate to rotate. When the first electric telescopic rod arranged inside the protective box contracts and the clamping block on the connecting gear enters the clamping groove, the connecting gear engages with the tooth groove on the outer gear plate to drive the second worm to rotate. At this time, the first electric telescopic rod rotates inside the protective box, and the rotation of the second worm will drive the second worm gear inside the protective box to rotate. The rotation of the second worm gear drives the rotating plate arranged inside the carrying plate to stand up and clamp the items placed on the carrying plate.

[0022] 3. When the rotating plate is erected, the display stand will squeeze the items on the carrier plate through the conveyor belt, and the torsion springs installed on the upper and lower sides of the connecting platform will cause the display stand to rotate, causing the slide on the display stand to slide inside the rotating plate. When the protrusion on the back of the slide enters the rotating plate and approaches the rotating plate, an electrical signal will be generated. The communication unit will know that the item is in a clamped state and will not activate the second electric telescopic rod to retract and press down to clamp the item.

[0023] 4. When the protrusion on the slide is not close to the rotating plate, the control unit cannot receive the signal from the rotating plate and will control the second electric telescopic rod to retract and lower the side display rack and the clamping head. After the clamping head clamps the item, the electrical rod on the inner wall of the clamping head contacts the electrode inside the side display rack to generate an electrical signal to stop the second electric telescopic rod from descending. The second spring generates elastic force when the side display rack rises, making it convenient to return the clamping head to its original state when taking out the goods or not clamping the goods later.

[0024] 5. When it is necessary to rotate only the carrying plate to adjust the direction, the first electric telescopic rod rises and the connecting gear disengages the clamping block from the clamping groove on the second worm. At this time, the first motor rotates forward and drives the rotating gear through the first worm, the connecting rod, and the first worm gear, so that the rotating gear drives the inner gear ring to rotate, thereby driving the carrying plate to adjust the direction of the object.

[0025] 6. When rising, the first motor reverses and drives the teeth on the groove wheel to reverse. During the process of reversal, the teeth will be supported by the notches on the surface of the groove wheel. Then the teeth engage with the notches on the surface of the transmission gear and drive the transmission gear and the double-headed screw to rotate, thereby driving the connecting arm to lift the carrier plate by the docking blocks connected on the surface of the double-headed screw to approach each other. At this time, the outer gear plate and the rotating ring come out of the notch in the robot base, and the rotating gear also disengages from the inner gear ring. Before rising, the clamped items are loosened. After rising, it is convenient to start the second motor to drive the conveyor belt to rotate and transport the goods on the surface, or manually take the goods away from the surface of the carrier plate.

[0039] See also Figure 1-11 , a vehicle-free carrier dispatching robot, comprising a robot base 1 and a carrying plate 6 for placing items, the front and rear ends of the robot base 1 are both equipped with protective components, a pair of moving wheels 4 are rotatably installed at the bottom end of the robot base 1, and the two moving wheels 4 are both equipped with a drive motor 401 on the side close to each other, a group of universal wheels 402 are installed on the lower surface of the robot base 1 away from the moving wheel 4, a carrying platform is provided on the top of the robot base 1, and lateral clamping mechanisms are provided on the left and right sides of the carrying platform, the carrying platform is composed of an outer gear disk 505 and a carrying plate 6, the inner surface of the outer gear disk 505 is equipped with a rotating ring 504, the rotating ring 504 and the outer gear disk 505 are placed in matching annular grooves opened on the upper surface of the robot base 1, an inner carrying cavity 8 is opened at the top of the robot base 1 just below the carrying plate 6, the interior of the inner carrying cavity 8 is equipped with a lifting component for lifting the carrying plate 6 and a rotating member for rotating the outer gear disk 505 and the carrying plate 6, and a transport component is also provided on the lateral clamping mechanism.

[0040] When the item is placed on the carrying plate 6, the first motor 5 rotates forward. Due to the setting of the first spring 5021 and the teeth 5022 on the groove wheel 502, it will not drive the transmission gear 605 to rotate. The first motor 5 will only drive the first worm 501 to rotate, and the first worm 501 drives the first worm wheel 507 to rotate. The first worm wheel 507 drives the rotating gear 607 to rotate through the connecting rod 506, and the rotating gear 607 drives the inner gear ring 503 to rotate, thereby driving the carrying plate 6 to rotate. At this time, the carrying plate 6 rotates on the inner wall of the outer gear plate 505 and the rotating ring 504, and the outer gear plate 505, the rotating ring 504 and the surface of the robot base 1 do not rotate. The top side of the connecting arm 602 rotates inside the limiting groove 606 through the slider. The rotation of the carrying plate 6 will drive the protective box 7 fixedly connected to the carrying plate 6 to rotate. When the first electric telescopic rod 7012 arranged inside the protective box 7 is contracted, the clamping block 7014 on the connecting gear 701 enters the clamping groove 701 After the first electric telescopic rod 701 is engaged with the teeth on the outer gear plate 505, it drives the second worm gear 7011 to rotate. At this time, the first electric telescopic rod 7012 rotates inside the protective box 7. The rotation of the second worm gear 7011 drives the second worm gear 712 inside the protective box 7 to rotate. The rotation of the second worm gear 712 drives the rotating plate 711 inside the carrying plate 6 to stand up and clamp the items placed on the carrying plate 6. When the rotating plate 711 is raised, the display rack 705 squeezes the items on the carrying plate 6. The torsion springs 706 installed on the upper and lower sides of the connecting platform 704 cause the display rack 705 to rotate, causing the slide plate 709 on the display rack 705 to slide inside the rotating plate 711. When the protrusion on the back of the slide plate 709 enters the rotating plate 711 and approaches the rotating plate 711, an electrical signal is generated. The communication unit detects that the item is clamped and stops activating the second electric telescopic rod 703 to retract and press down to clamp the item, allowing the robot base 1 to transport it.

[0041] Specifically, the front detection unit 2 and the rear detection unit 3 are both equipped with a visual camera unit and a millimeter-wave radar unit. The front detection unit 2 is also equipped with a communication unit and a control unit. The visual camera unit can grasp the environmental picture in real time, and the millimeter-wave radar unit can detect obstacles in the moving area to avoid the robot base 1 from colliding with obstacles during movement. The configured communication unit sends the status of the robot base 1 or other electrical signals generated by operations to the background server to facilitate operation, maintenance, management and control through the background server. The control unit can integrate the visual camera unit and the millimeter-wave radar unit to regulate the moving speed and transportation route of the robot base 1, and at the same time control and process other operations and functions of the robot.

[0042] Specifically, the protection component is composed of a pair of anti-collision frames 101 fixedly installed at the front end of the robot base 1 and a pair of anti-collision frames 102 fixedly installed at the rear end of the robot base 1. The anti-collision frames 101 and 102 can provide effective protection when the robot base 1 collides.

[0043] Specifically, the lifting assembly includes a power part and a telescopic part. The power part includes a first motor 5. A first worm 501 is installed at the output end of the first motor 5. A groove wheel 502 is installed at one end of the first worm 501. A first spring 5021 is installed in the groove on the surface of the groove wheel 502. The top of the first spring 5021 is connected to a tooth 5022.

[0044] Specifically, the first motor 5 is fixedly mounted on the inner wall of the inner bearing cavity 8 , and the sheave 502 is rotatably connected to the inner wall of the inner bearing cavity 8 .

[0045] Specifically, the telescopic part includes a transmission gear 605, the tooth grooves on the surface of the transmission gear 605 are matched with the teeth 5022, the surface of the transmission gear 605 is installed with a double-headed screw 604, the front and back of the double-headed screw 604 are connected to the docking block 603, the surface of the docking block 603 is connected to the connecting arm 602, the four connecting arms 602 are hinged at the head and tail, the bottom wall of the supporting plate 6 is provided with a limiting groove 606, the top side of the connecting arm 602 is connected to a slider through a connecting shaft, and the slider is slidably arranged in the limiting groove 606.

[0046] When rising, the first motor 5 reverses and drives the teeth 5022 on the groove wheel 502 to reverse. During the reversal of the teeth 5022, they will be supported by the notches opened on the surface of the groove wheel 502. Then the teeth 5022 engage with the notches on the surface of the transmission gear 605 to drive the transmission gear 605 and the double-headed screw 604 to rotate, thereby driving the connecting arm 602 to lift the supporting plate 6 to rise through the docking blocks 603 connected to the surface of the double-headed screw 604. At this time, the outer gear plate 505 and the rotating ring 504 come out of the notches in the robot base 1, and the rotating gear 607 also disengages from the inner gear ring 503. Before rising, the clamped items are loosened. After rising, it is convenient to start the second motor 708 to drive the conveyor belt 707 to rotate to transport the goods on the surface, or manually take the goods away from the surface of the supporting plate 6.

[0047] Specifically, the rotating part includes a connecting rod 506, a first worm gear 507 is installed on the surface of the connecting rod 506, the first worm gear 507 is meshingly connected with the first worm 501, the connecting rod 506 is rotatably arranged on the bottom wall surface of the inner bearing cavity 8, a rotating gear 607 is installed on the top side of the connecting rod 506, the surface of the rotating gear 607 is meshingly connected with the inner gear ring 503, and the inner gear ring 503 is fixedly installed with the bearing plate 6.

[0048] When it is necessary to rotate only the carrying plate 6 to adjust the direction, the first electric telescopic rod 7012 rises and connects the gear 701 to disengage the clamping block 7014 from the clamping groove 7013 on the second worm 7011. At this time, the first motor 5 rotates forward. Due to the setting of the first spring 5021 and the teeth 5022 on the groove wheel 502, it will not drive the transmission gear 605 to rotate. The first motor 5 will only drive the first worm 501 to rotate, and the first worm 501 drives the first worm gear 507 to rotate. The first worm gear 507 drives the rotating gear 607 to rotate through the connecting rod 506, and the rotating gear 607 drives the inner gear ring 503 to rotate, thereby driving the carrying plate 6 to rotate. At this time, the carrying plate 6 rotates on the inner wall of the outer gear plate 505 and the rotating ring 504, and the outer gear plate 505, the rotating ring 504 and the surface of the robot base 1 do not rotate. The top side of the connecting arm 602 rotates inside the limiting groove 606 through the slider. The rotation of the carrying plate 6 can adjust the orientation position of the object.

[0049] Specifically, the lateral clamping mechanism includes a protective box 7, which is fixedly installed on the side of the supporting plate 6. The interior of the protective box 7 is rotatably connected to the first electric telescopic rod 7012, and the outer surface of the first electric telescopic rod 7012 is rotatably connected to the second worm 7011. The top side of the first electric telescopic rod 7012 is installed with a connecting gear 701, and the bottom side of the connecting gear 701 is installed with a clamping block 7014. The top side of the second worm 7011 is provided with a clamping groove 7013, and the clamping groove 7013 and the clamping block 7014 are arranged in a cross shape. The connecting gear 701 is meshed with the surface of the outer gear plate 505.

[0050] Specifically, the surface of the second worm 7011 is meshed with the second worm gear 712, and a rotating rod 713 is installed inside the second worm gear 712. The surfaces at both ends of the rotating rod 713 extend to the inside of the carrying disk 6 and are connected to the rotating plate 711. The rear surface of one side of the carrying disk 6 is installed with the first proximity switch 601. The top side of the rotating plate 711 is installed with the second electric telescopic rod 703, the output end of the second electric telescopic rod 703 is installed with the side display frame 702, the bottom side of the side display frame 702 is installed with a clamping head 710, the inside of the side display frame 702 is installed with an electrode 7022, and second springs 7021 are installed on both sides of the electrode 7022. The inner wall of the connecting gear 701 is installed with an electric rod 7023.

[0051] When the first electric telescopic rod 7012 provided inside the protective box 7 is contracted to make the clamping block 7014 on the connecting gear 701 enter the clamping groove 7013, the connecting gear 701 is engaged with the tooth groove on the outer gear plate 505 to drive the second worm 7011 to rotate. At this time, the first electric telescopic rod 7012 rotates inside the protective box 7, and the rotation of the second worm 7011 will drive the second worm gear 712 inside the protective box 7 to rotate. The rotation of the second worm gear 712 drives the rotating plate 711 provided inside the carrying disk 6 to stand up and clamp the items placed on the carrying disk 6. When the rotating plate 711 is set up, the display rack 705 will squeeze the items on the carrying disk 6 through the conveyor belt 707, and the torsion springs 706 installed on the upper and lower sides of the connecting platform 704 will cause the display rack 705 to rotate, so that the slide plate on the display rack 705 709 slides inside the rotating plate 711. When the protrusion on the back of the slide 709 enters the rotating plate 711 and approaches the rotating plate 711, an electrical signal is generated, and the communication unit will know that the item is in a clamped state. When the protrusion on the slide 709 is not close to the rotating plate 711, the rotating plate 711 contacts the first proximity switch 601 to generate an electrical signal, which causes the control unit to control the second electric telescopic rod 703 to retract and lower the side display rack 702 and the clamping head 710. After the clamping head 710 clamps the item, the electrical rod 7023 on the inner wall of the clamping head 710 contacts the electrode 7022 inside the side display rack 702, generating an electrical signal to stop the second electric telescopic rod 703 from descending. The second spring 7021 generates elastic force when the side display rack 702 rises, so that the clamping head 710 can return to its original state when the goods are taken out later.

[0052] Specifically, the transport assembly includes a connecting platform 704, which is fixedly mounted to a rotating plate 711. An exhibition stand 705 is rotatably connected to the upper and lower sides of the connecting platform 704. A torsion spring 706 is installed between the exhibition stand 705 and the connecting platform 704. A second motor 708 is installed on the top side of the exhibition stand 705. The output end of the second motor 708 is connected to a conveyor belt 707 via a connecting shaft. A rotating shaft is connected to the inside of the other side of the conveyor belt 707. The rotating shaft is rotatably connected to the exhibition stand 705. A slide 709 is installed on the top side of the exhibition stand 705. The other end of the slide 709 is provided with a protrusion. The slide 709 passes through the rotating plate 711 and slides with the rotating plate 711. A second proximity switch 714 is installed through the interior of the rotating plate 711 and the slide 709 at a horizontal position.

[0053] When the rotating plate 711 is erected, the display rack 705 squeezes the articles on the carrying plate 6 through the conveyor belt 707. The torsion springs 706 installed on the upper and lower sides of the connecting platform 704 cause the display rack 705 to rotate, causing the slide plate 709 on the display rack 705 to slide inside the rotating plate 711. When the protrusion on the back of the slide plate 709 enters the rotating plate 711 and approaches the rotating plate 711, an electrical signal is generated. The communication unit will know that the articles are in a clamped state, and the second electric telescopic rod 703 will not be activated to retract and clamp the articles. When the articles on the carrying plate 6 need to be transported, the second motor 708 is activated to drive the conveyor belt 707 to rotate and transport the goods on the surface.

[0054] Working principle: When the item is placed on the carrying plate 6, the first motor 5 rotates forward. Due to the setting of the first spring 5021 and the teeth 5022 on the groove wheel 502, it will not drive the transmission gear 605 to rotate. The first motor 5 will only drive the first worm 501 to rotate, and the first worm 501 drives the first worm wheel 507 to rotate. The first worm wheel 507 drives the rotating gear 607 to rotate through the connecting rod 506, and the rotating gear 607 drives the inner gear ring 503 to rotate, thereby driving the carrying plate 6 to rotate. At this time, the carrying plate 6 rotates on the inner wall of the outer gear plate 505 and the rotating ring 504, and the outer gear plate 505, the rotating ring 504 and the surface of the robot base 1 do not rotate. The top side of the connecting arm 602 rotates inside the limiting groove 606 through the slider, and the carrying plate 6 rotates It will drive the protection box 7 fixedly connected to the carrying plate 6 to rotate. When the first electric telescopic rod 7012 arranged inside the protection box 7 contracts to make the clamping block 7014 on the connecting gear 701 enter the clamping groove 7013, the connecting gear 701 engages with the tooth groove on the outer gear plate 505 to drive the second worm 7011 to rotate. At this time, the first electric telescopic rod 7012 rotates inside the protection box 7. The rotation of the second worm 7011 will drive the second worm gear 712 inside the protection box 7 to rotate. The rotation of the second worm gear 712 drives the rotating plate 711 arranged inside the carrying plate 6 to stand up and clamp the items placed on the carrying plate 6. When the rotating plate 711 is set up, the conveyor belt 707 inside the display rack 705 will squeeze the items on the carrying plate 6. The torsion springs 706 installed on the upper and lower sides of the connecting platform 704 cause the display rack 705 to rotate, causing the slide plate 709 on the display rack 705 to slide inside the rotating plate 711. When the protrusion on the back of the slide plate 709 enters the rotating plate 711 and approaches the rotating plate 711, an electrical signal is generated. The communication unit will know that the item is in a clamped state and will not start the second electric telescopic rod 703 to retract and press down to clamp the item so that the robot base 1 can transport it. When the protrusion on the slide plate 709 does not approach the rotating plate 711, the rotating plate 711 contacts the first proximity switch 601 to generate an electrical signal, which will control the control unit to control the second electric telescopic rod 703 to retract and lower the side display rack 702 and the clamping head 710. After the clamping head 710 clamps the item, the electric signal on the inner wall of the clamping head 710 is generated. The contact between the electric rod 7023 and the electrode 7022 inside the side display frame 702 generates an electrical signal to stop the second electric telescopic rod 703 from descending. The second spring 7021 generates elastic force when the side display frame 702 rises, which is convenient for taking out the goods later or returning the clamping head 710 to its original state when the goods are not clamped. When it is necessary to rotate only the carrying plate 6 to adjust the direction, the first electric telescopic rod 7012 rises and connects the gear 701 to disengage the clamping block 7014 from the clamping groove 7013 on the second worm 7011. At this time, the direction of the article can be adjusted. When rising, the first motor 5 reverses and drives the teeth 5022 on the groove wheel 502 to reverse. During the reversal of the teeth 5022, they are supported by the notches on the surface of the groove wheel 502.The teeth 5022 then mesh with the notches on the surface of the transmission gear 605, driving the transmission gear 605 and the double-headed screw 604 to rotate. This, in turn, causes the docking block 603 connected to the surface of the double-headed screw 604 to approach each other, driving the connecting arm 602 to lift the carrier plate 6 upward. At this point, the outer gear plate 505 and the rotating ring 504 emerge from the notches in the robot base 1, and the rotating gear 607 also disengages from the inner gear ring 503. Before the lift is lifted, the clamped items are released. After the lift is lifted, it is easy to activate the second motor 708 to drive the conveyor belt 707 to rotate and transport the goods on the surface, or to manually remove the goods from the surface of the carrier plate 6.
