Description

Technical Field

[0001] This utility model relates to the field of express delivery robot technology, specifically to an express delivery robot's express delivery storage and retrieval warehouse. Background Technology

[0002] Express delivery, also known as courier or freight, refers to a new type of transportation in which logistics companies (including freight forwarders) use their own independent networks or joint ventures (i.e., networked operations) to quickly and safely deliver documents or parcels entrusted by users from the sender to the recipient's door. Express delivery can be broadly or narrowly defined. In a broad sense, express delivery refers to any goods (including bulk shipments). In a narrower sense, express delivery refers specifically to the urgent delivery service of business documents and small packages. Express delivery is a new mode of transportation and an important link in the supply chain. To solve the last-mile delivery problem, express delivery robots have emerged. Existing express delivery robots consist of two parts: a package storage and retrieval compartment and an intelligent mobile chassis. Staff at the express station place the packages to be delivered into the storage and retrieval compartment in sequence and number them, then close the compartment door. The intelligent mobile chassis carries the package storage and retrieval compartment to different delivery locations. After the user inputs a command, the corresponding electronically controlled compartment door opens automatically, and the user can quickly retrieve the package. Traditional express delivery robots are integrated robots, with the package storage and retrieval compartment and the intelligent mobile chassis as one unit. After delivering one batch of packages, the robot needs to return to the express station to store the next batch of packages. During storage, different compartment doors need to be opened sequentially to place the packages in and number them, which is time-consuming, labor-intensive, and affects delivery efficiency. Packages may be bumped and shaken during transportation. Cylindrical packages are prone to rolling to the side of the compartment door. When the compartment door opens automatically, packages are prone to falling and being damaged. Small packages may even roll into the depths of the compartment, making it inconvenient for users to quickly retrieve them. Therefore, we propose an express delivery robot's package storage and retrieval compartment. Utility Model Content

The storage compartments are all slidably connected to the inside of the mounting frame. The front side of the inside of each storage compartment has a mounting groove. The limiting blocks are all slidably connected to the inside of the mounting groove. The limiting grooves are all located on the rear side of the inside of the limiting blocks. The locking posts are all slidably connected to the rear side of the inside of the mounting groove. The inner end of each locking post is installed by engaging with the inner wall of the vertically adjacent limiting groove through the limiting post. Each locking post is installed by engaging with the inner wall of the mounting frame through a locking hole. A spring is provided between the inner wall of the mounting groove and the middle of the limiting block. The spring is sleeved on the front end of the outer surface of the limiting block, providing a basis for fixing and releasing the storage compartment. It adopts a split design with a side door for storage, which can quickly store express packages and change storage and retrieval compartments, improving the conveying efficiency. The pull-out compartment can quickly retrieve express packages while preventing them from falling.

[0007] Furthermore, the storage compartments are symmetrically distributed from left to right, and each compartment has a partition in the middle, which can increase the storage capacity of express packages.

[0008] Furthermore, the access mechanism also includes an opening and closing assembly, which includes sliding columns, sliders, and electric push rods. The sliding columns are all located inside the front side of the housing, and a slider is located between two sliding columns. The electric push rods are respectively located on the left and right sides of the upper end of the slider. The input end of the electric push rod is electrically connected to the output end of the microcontroller, providing a basis for the opening and closing of the storage compartment.

[0009] Furthermore, the storage and retrieval mechanism also includes electromagnetic chucks, which are all located at the rear end of the telescopic end of the electric push rod. The input end of the electromagnetic chuck is electrically connected to the output end of the microcontroller, and the rear end of the electromagnetic chuck is installed in conjunction with the front end of the storage compartment on the same side, which can quickly fix and release the storage compartment.

[0010] Furthermore, the access mechanism also includes a drive assembly, which includes a lead screw, a motor, a worm gear, and a worm wheel.

The worm wheel is located at the lower end of the outer surface of the lead screw. The worm gear and the worm wheel are meshed and connected to provide a stable drive for the opening and closing of different storage compartments.

[0011] Furthermore, both the left and right sides of the housing are hinged with side doors via upper hinges, and each side door has a handle in the middle on the side away from the center of the housing, which allows for quick storage of packages.

[0012] Furthermore, it also includes a microcontroller, which is located in the front center of the housing. The input terminal of the microcontroller is electrically connected to an external power source to provide control for the storage of express packages.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The parcel storage and retrieval compartment of this parcel robot has the following advantages:

[0014] 1. By opening and closing the side door, packages can be stored from the side, improving storage efficiency. The split design separates the storage compartment from the external mobile chassis, allowing new storage compartments to be prepared in advance. When transporting the next batch of packages, only the new storage compartment needs to be replaced, thus improving transport efficiency.

[0015] 2. The microcontroller controls the motor to run, and the meshing of the worm and worm wheel drives the lead screw to rotate, changing the position of the electric push rod, thereby quickly pushing out different storage compartments. At the same time, the electromagnetic chuck generates a magnetic field to move the limit block to fix and release the storage compartment, which can quickly retrieve the package. The U-shaped storage compartment can also prevent the package from falling. Attached Figure Description

[0023] Please see Figure 1-5This embodiment provides a technical solution: a parcel storage and retrieval compartment for a parcel robot, including a shell 1 and a storage and retrieval mechanism 4;

[0024] Housing 1: The rear side of the housing is provided with a mounting bracket 2, and also includes a microcontroller 5. The microcontroller 5 is located in the middle of the front end of the housing 1. The input terminal of the microcontroller 5 is electrically connected to an external power supply to provide control for the storage of express items.

[0025] Access mechanism 4 includes a storage compartment 41, a limiting block 42, a limiting groove 43, a locking pin 44, and a spring 45. The storage compartments 41 are slidably connected to the interior of the mounting frame 2. Each storage compartment 41 has a mounting groove 3 on its front interior side. The limiting blocks 42 are slidably connected to the interior of the mounting groove 3. The front end of each limiting block 42 is made of iron. The limiting grooves 43 are located on the rear interior side of each limiting block 42. The locking pins 44 are slidably connected to the rear interior side of each mounting groove 3. The inner ends of the locking pins 44 are fitted with the inner walls of the vertically adjacent limiting grooves 43 via the limiting pins. The limiting grooves 43 can press the locking pins 44 through the limiting pins, causing the locking pins 44 to shift. The locking pins 44 are fitted with the inner walls of the mounting frame 2 via locking holes. Bluetooth is used for... Locking pins 44 are inserted into and removed from locking holes to fix and release storage compartments 41. Springs 45 are provided between the inner wall of the mounting groove 3 and the middle of the limiting block 42. The springs 45 are all sleeved on the front end of the outer surface of the limiting block 42, providing a basis for fixing and releasing the storage compartments 41. The storage compartments 41 are symmetrically distributed left and right. Each storage compartment 41 has a partition in the middle, dividing it into front and rear cavities, which can increase the storage capacity of express items. The storage and retrieval mechanism 4 also includes an opening and closing assembly 46, which includes sliding pins 461, sliders 462, and electric push rods 463. The sliding pins 461 are all located on the front side of the inner side of the housing 1, and a slider 462 is provided between two sliding pins 461. The electric push rods 463 are respectively located on the sliders 462. On the upper left and right sides, the input end of the electric push rod 463 is electrically connected to the output end of the microcontroller 5, providing a basis for the opening and closing of the storage compartment 41. The storage and retrieval mechanism 4 also includes an electromagnetic chuck 47, which is located at the rear end of the telescopic end of the electric push rod 463. The input end of the electromagnetic chuck 47 is electrically connected to the output end of the microcontroller 5. The rear end of the electromagnetic chuck 47 is installed in conjunction with the front end of the storage compartment 41 on the same side, which can quickly fix and release the storage compartment 41. The storage and retrieval mechanism 4 also includes a drive assembly 48, which includes a lead screw 481, a motor 482, a worm gear 483, and a worm wheel 484. The lead screw 481 is rotatably connected to the middle of the front side of the inner side of the housing 1. The motor 482 is located at the middle of the front side of the bottom wall of the housing 1. The input of the motor 482 is... The output terminal of the microcontroller 5 is electrically connected. The worm gear 483 is located at the front end of the output shaft of the motor 482, and the worm wheel 484 is located at the lower end of the outer surface of the lead screw 481. The worm gear 483 and the worm wheel 484 are meshed and connected to provide a stable drive for the opening and closing of different storage compartments 41. The left and right sides of the housing 1 are hinged with side doors 49 through the upper hinge. Each side door 49 has a handle in the middle on the side away from the middle of the housing 1. Opening one side door 49 can fill all the storage compartments 41 on that side with packages, which can quickly store packages. The separate design with the side door 49 for storage can quickly store packages and change storage compartments, improving the conveying efficiency. The pull-out compartment can quickly retrieve packages while preventing them from falling.

[0026] The working principle of the parcel storage and retrieval compartment of the parcel delivery robot provided by this utility model is as follows: When using the parcel delivery robot to deliver parcels, open the side doors 49 on both sides, and place the parcels to be delivered into different cavities from the side of the storage compartment 41 in sequence. The parcels delivered first are placed in the rear cavity, and the parcels delivered later are placed in the front cavity. Then close the side doors 49, install the storage and retrieval compartment on the external intelligent mobile chassis, and form the parcel delivery robot. The intelligent mobile chassis moves the storage and retrieval compartment to the delivery location. After the user inputs the command, the microcontroller 5 controls the motor 482 to run. The output shaft of the motor 482 drives the worm gear 483 to rotate. Because the worm gear 483 is meshed with the worm wheel 484, the worm wheel 484 also rotates synchronously, driving the lead screw 481 to rotate as well. When the lead screw 481 rotates clockwise, the slider 462 moves upward; when the lead screw 481 rotates counterclockwise, the slider 462 moves downward. This continues until the slider 462 reaches the appropriate position, and the electric push rod 463 aligns with the corresponding storage compartment 41. The microcontroller 5 controls the electric push rod 463 to operate, extending its telescopic end backward. The electromagnetic chuck 47 also moves backward. When the electromagnetic chuck 47 is about to contact the front end of the corresponding storage compartment 41, the microcontroller 5 controls the electromagnetic chuck 47 to be energized. The electromagnetic chuck 47 contacts the front end of the storage compartment 41. At this time, the storage compartment 41 is still in a fixed state. The electromagnetic chuck 47 generates a magnetic field, which attracts the iron limiting block 42. The limiting block 42 moves forward, compressing the spring 45 until the front end of the limiting block 42 is attracted to the electromagnetic chuck 462. At the rear end of 7, as the limiting block 42 moves, the limiting groove 43 squeezes the locking pin 44 through the limiting post, causing the locking pin 44 to move inward synchronously until the outer end of the locking pin 44 is completely out of the locking hole. At this time, the storage compartment 41 is released, and the telescopic end of the electric push rod 463 continues to extend. The electromagnetic chuck 47 can be firmly fixed to the front end of the storage compartment 41 through the limiting block 42, pushing the storage compartment 41 out of the mounting bracket 2 until the partition is aligned with the right end of the mounting bracket 2. At this time, the rear cavity is fully exposed, and the user can quickly take out the package from the rear cavity. When it is necessary to take out the package from the front cavity, simply extend the telescopic end of the electric push rod 463 to expose the front cavity out of the mounting bracket 2. After the package is taken out, the microcontroller... 5. The electric push rod 463 is controlled to operate. The telescopic end of the electric push rod 463 retracts forward, and the storage compartment 41 moves forward accordingly. When the storage compartment 41 moves to the point where the locking pin 44 aligns with the locking hole, the microcontroller 5 controls the electromagnetic chuck 47 to be de-energized. The magnetic field of the electromagnetic chuck 47 disappears, the spring 45 expands without force, and the limit block 42 returns to its original position. The limit groove 43 presses against the locking pin 44, causing the outer end of the locking pin 44 to insert into the locking hole, and the storage compartment 41 is fixed. Then, the next package is transported. After a batch of packages is transported, the robot moves to the express station to transport the next batch of packages. At this time, it is only necessary to remove the previous storage compartment and then install the new storage compartment with the pre-stored packages on the intelligent mobile chassis to form the express robot.This allows for the rapid delivery of the next batch of packages, improving delivery efficiency.

[0027] It is worth noting that the microcontroller 5 disclosed in the above embodiments is an S7-200 microcontroller, the electric actuator 463 is a TYSC95 electric actuator, the electromagnetic chuck 47 is a DC12V electromagnetic chuck, and the motor 482 is a UIM242 motor. The microcontroller 5 controls the operation of the electric actuator 463, the electromagnetic chuck 47, and the motor 482 using methods commonly used in the prior art.
