Description

Technical Field

[0001] This utility model relates to the field of material handling robot technology, specifically to a material handling trolley. Background Technology

[0002] With the continuous development of mechanical automation, people are using automation in various parts of factories to improve work efficiency, thereby continuously improving production. In recent years, research on transport trolleys has received increasing attention, and a series of competitions have been launched both domestically and internationally. In practical applications, various mechanisms and sensors are installed on transport trolleys to give them different working capabilities. At the same time, transport trolleys are constantly developing towards intelligence and automation, making transport work more convenient and simpler.

[0003] A Chinese patent with publication number CN111872917A discloses an intelligent logistics handling vehicle, including a mobile chassis. A robotic arm is mounted on the top of the mobile chassis, and a set of material collection boxes are also mounted on the top of the mobile chassis. The robotic arm is equipped with a barcode scanning device, and the front of the mobile chassis is equipped with an infrared tracking device and an ultrasonic obstacle avoidance device. The barcode scanning device scans and identifies the materials, and the robotic arm grabs the materials and places them into the corresponding material collection boxes. After reaching the target location by tracking, the robotic arm grabs the materials from the material collection boxes on the vehicle body and places them in the corresponding positions. However, during the grabbing process, if the object is lower than the groove of the material collection box on the vehicle body or the object fills the groove, it is difficult for the robotic arm to reach into the groove to remove the object. Utility Model Content

[0004] The main purpose of this utility model is to overcome the defects of the above-mentioned background technology and provide a material handling trolley.

[0005] To achieve the above objectives, this utility model proposes a material handling trolley, in which the robotic arm and the storage basket are both mounted on the trolley body. The trolley body is provided with a lifting mechanism corresponding to the storage basket. The lifting mechanism includes a driving component, a turntable, a lifting rod, and a lifting block. The top surface of the trolley body has a through hole. The turntable is rotatably mounted on the top surface of the trolley body and covers the through hole. The driving component is mounted on the trolley body, and its output end is connected to the turntable. The storage basket is mounted on the top surface of the turntable, and a tray is movably connected to the bottom surface of the storage basket. One end of the lifting rod is connected to the bottom of the tray, and the other end of the lifting rod passes through the turntable and the through hole. The lifting block is located inside the trolley body and cooperates with the bottom end of the lifting rod. The lifting block is shaped like a wave crest. When the robotic arm needs to grip an object in the storage basket, the drive unit operates, causing the turntable to rotate. The push rod on the turntable rotates and moves synchronously to abut against the top block. The push rod continues to move upward along the crest of the top block to lift the tray, moving the object placed on the tray to the opening of the storage basket, making it easier for the robotic arm to grip the object.

[0006] To further optimize the technical solution, a mounting plate is provided inside the vehicle body, the drive component is mounted on the mounting plate, and the top block is mounted on the top surface of the mounting plate. This avoids the drive component being installed outside the vehicle body, which would affect the normal operation of the robotic arm and reduce the working space of the robotic arm. At the same time, installing the drive component internally can protect it from collisions.

[0007] The technical solution has been further optimized by incorporating a hollowed-out interior for the vehicle body. This hollowed-out structure facilitates heat dissipation from the drive components and other moving parts.

[0008] To further optimize the technical solution, a sleeve is provided at the bottom of the turntable to cooperate with the push rod. The cooperation between the push rod and the sleeve facilitates the smooth movement of the push rod.

[0009] The technical solution is further optimized so that the sleeve body mates with the wall of the through hole. The sleeve provides radial support for the output shaft of the drive component, facilitating stable rotation of the turntable.

[0010] To further optimize the technical solution, a guide plate is provided on the side of the top block. This prevents the top rod from slipping and deviating under force when the top block lifts the top rod.

[0011] To further optimize the technical solution, the top block is located at the end of the vehicle body away from the robotic arm. By rotating the turntable to change the position of the storage basket, the top block and top rod at the end of the vehicle body cooperate to lift the objects one by one, and then the robotic arm clamps them. This facilitates the control of the robotic arm's clamping position, reduces the rotation angle of the robotic arm's operation, and improves work efficiency.

[0012] To further optimize the technical solution, a collision-resistant baffle is provided at one end of the vehicle body. This baffle prevents the transport trolley from colliding with other items or hitting the storage platform during its movement, thus avoiding damage to components.

[0013] To further optimize the technical solution, a retaining ring is installed on the vehicle body. This retaining ring prevents items from accidentally slipping off the storage basket.

[0014] The technical solution has been further optimized, with the bottom of the push rod being spherical. This facilitates smooth movement of the push rod on the top block.

[0015] The beneficial effects of this utility model include: by setting up a lifting mechanism, when the robot needs to grip an object in the storage basket, the lifting mechanism can lift the object; the lifting mechanism drives the turntable to rotate through the drive component, and the top rod on the turntable rotates around the turntable axis and then abuts against the top block. The top rod continues to move upward along the crest of the top block to lift the tray, and moves the object placed on the tray to the opening of the storage basket, making it easier for the robot to grip the object.

The top block 44 is located inside the vehicle body 1 and corresponds to the bottom end of the top rod 43. The top block 44 is shaped like a crest. In this embodiment, when the robot arm 2 needs to grip the object in the basket 3, it first drives the turntable 42 to rotate through the drive component 41. The top rod 43 on the turntable 42 rotates and moves synchronously to abut against the top block 44. The top rod 43 continues to move into the crest section of the top block 44, lifting the tray 31 and causing the object placed on the tray 31 to rise and move to the opening of the basket 3, making it easier for the robot arm 2 to grip the object.

[0026] In a preferred embodiment, a mounting plate 12 is fixedly installed inside the vehicle body 1, a drive component 41 is fixedly installed on the mounting plate 12, and a top block 44 is fixedly installed on the top surface of the mounting plate 12; this avoids installing the drive component 41 on the top surface of the vehicle body 1, thus reducing the working space of the robotic arm 2, while installing the drive component 41 inside can protect the drive component 41 from collisions.

[0027] In a preferred embodiment, the interior of the vehicle body 1 is hollowed out; the hollowed-out structure facilitates heat dissipation from the drive component 41 and other moving parts.

[0028] In a preferred embodiment, the bottom of the turntable 42 is provided with a sleeve 5 that cooperates with the push rod 43; the cooperation between the push rod 43 and the sleeve 5 facilitates the smooth movement of the push rod 43.

[0029] In a preferred embodiment, the cylinder bodies of multiple sleeves 5 are fitted with the wall of the through hole 11; the sleeves 5 provide radial support for the output shaft of the drive member 41, so that the turntable 42 can rotate stably.

[0030] In a preferred embodiment, a guide plate 6 is provided on the side of the top block 44 to prevent the top rod 43 from slipping and deviating under force when the top block 44 lifts the top rod 43.

[0031] In a preferred embodiment, the top block 44 is located at the end of the vehicle body 1 away from the robot arm 2; the position of the storage basket 3 is changed by rotating the turntable 42, so that the storage basket 3 is rotated to the end away from the robot arm 2, and the top block 44 and the top rod 43 cooperate to lift the object, and the robot arm 2 clamps it, which facilitates the control of the clamping position of the robot arm 2, while reducing the rotation angle of the robot arm 2 and improving work efficiency.

[0032] In a preferred embodiment, the end of the vehicle body 1 with the storage basket 3 is provided with a collision protection plate 7; the collision protection plate 7 is preferably made of PE resin material, and the collision protection plate 7 prevents the vehicle body 1 from colliding with other items during the movement of the transport trolley, impacting the storage basket 3 and the turntable 42, and causing damage to the components.

[0033] In a preferred embodiment, a retaining ring 8 is provided on the vehicle body 1; the retaining ring 8 is installed outwardly around the turntable 42, and the retaining ring 8 is preferably made of PE resin. The retaining ring 8 prevents items from accidentally slipping off the storage basket 3 after the lifting mechanism 4 lifts the tray 31 during the transportation process.

[0034] In a preferred embodiment, the bottom of the push rod 43 is spherical, which facilitates the smooth movement of the push rod 43 on the top block 44.

[0035] Working principle: During the transport process, the trolley moves along the storage basket 3, carrying the items to the designated location. The drive unit 41 on the mounting plate 12 is activated, driving the turntable 42 to rotate. The turntable 42 drives the storage basket 3 to rotate, and the sleeve 5 slides along the wall of the through hole 11 of the trolley body 1 under the influence of the turntable 42. When one of the storage baskets 3 rotates to a position on the trolley body 1 away from the robot arm 2, the turntable 42 simultaneously drives the push rod 43 to rotate and move, abutting against the top block 44. The push rod 43 moves upward along the crest section of the top block 44 between the two guide plates 6, lifting the tray 31 and moving the items placed on the tray 31 to the opening of the storage basket 3. The drive unit 41 then stops. During operation, the robotic arm 2 clamps and moves the object. After the moving action, the drive unit 41 continues to operate, rotating the next storage basket 3 to a position on the vehicle body 1 away from the robotic arm 2, preparing for the next moving operation. After the storage basket 3 has completed the moving operation, it leaves the position on the vehicle body 1 away from the robotic arm 2, and the top rod 43 leaves the top block 44. The top rod 43 and the tray 31 slide downward under gravity, and the tray 31 lands at the bottom of the storage basket 3. In the event of an accidental collision, the impact at the rear first contacts the anti-collision baffle 7 to prevent the storage basket 3 and the turntable 42 from being impacted. When the object is being moved, if the object accidentally rolls off, it is blocked by the retaining ring 8 to prevent the object from falling out of the vehicle body 1.
