Description

Technical Field

[0001] The utility model belongs to the technical field of scheduling equipment, and particularly relates to a multi-objective flow shop scheduling equipment. Background Art

[0002] Flow shop scheduling (also known as pipeline scheduling) refers to the process of effectively arranging and coordinating production resources (such as equipment, personnel, materials) in a manufacturing environment, especially in an environment involving multi-stage continuous production. The goal is to optimize the production process, improve efficiency, reduce waiting time, balance the workload, and ensure the timely completion of production tasks. In modern manufacturing, efficient flow shop scheduling is an important part of realizing lean production, agile manufacturing, and intelligent manufacturing.

[0003] For example, a multi-objective flow shop scheduling equipment with the publication number CN216761829U includes a bottom plate. One side of the bottom plate is fixedly installed with a bracket. One side of the bracket is fixedly installed with a plurality of cross plates. A second sensor is installed on one side of the cross plate. A chute is opened at the top of the cross plate. A material placement plate is slidably connected to the top of the cross plate. A slider is fixedly installed at the bottom of the material placement plate. The slider is slidably connected to the chute. A third sensor is installed on the top of the material placement plate. A buffer block is arranged inside the chute and on one side of the slider. The beneficial effect of the utility model is that by installing a servo motor to drive the rotating column to rotate, the telescopic rod and the fixture at its top can be used to clamp the material with the fixture and place it on the material rack during material scheduling in loading, thus saving the physical strength of employees and avoiding the consumption of a large amount of physical strength by employees during material scheduling, which affects work efficiency during work.

[0004] This scheduling equipment needs human assistance during use. When the workload in the workshop is too large, it is impossible to provide manpower to control the scheduling equipment. At the same time, in the prior art, robots are used for workshop scheduling. When the workload in the workshop is small, the robots do not need to work and will occupy a large area. To solve the above problems, a multi-objective flow shop scheduling equipment is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a multi-objective flow shop scheduling equipment to solve the above problems, including:

[0006] A mobile shelf, at the lower end of the front side of which there is a storage bin. An electric telescopic rod is fixedly installed at the top inside the storage bin. The end of the output shaft of the electric telescopic rod is fixedly installed with a first electromagnet.

[0007] The mobile robot has a traction chain fixedly installed on the outer wall of its rear side. One side of the traction chain away from the mobile robot is fixedly installed on the outer wall of the front side of the mobile rack. A rotating seat is fixedly installed on the upper surface of the mobile robot. A second electromagnet is magnetically connected to the upper surface of the rotating seat. A four-axis robotic arm is fixedly installed on the upper surface of the second electromagnet. A mechanical clamp is fixedly installed at the end of the four-axis robotic arm.

[0008] Through the above technical solution, when the workload in the workshop is high, the mobile robot drives the mobile rack to move inside the workshop, and the four-axis robotic arm cooperates with the mechanical clamp to transfer goods in the workshop, greatly reducing the manpower requirement and the workload in the workshop. When the workload in the workshop is low, the mobile robot enters the storage bin. The electric telescopic rod extends, and the first battery iron at its end magnetically attracts the mobile robot to fix it inside the storage bin. At this time, the mobile rack can be fixed to act as a shelf, providing a function even when not working.

[0009] In a preferred embodiment, universal wheels are fixedly installed at the four corners of the bottom of the mobile rack.

[0010] In a preferred embodiment, a push handle is fixedly installed on one side of the upper end of the mobile rack.

[0011] Through the above technical solution, when the load on the vehicle frame is low, the staff can push the mobile rack through the push handle.

[0012] In a preferred embodiment, two clamping rods are arranged on the outer wall of the front side of the mechanical clamp. A fixed seat is fixedly installed on one side outer wall of the clamping rod. A climbing wheel is rotatably connected to one side of the fixed seat. A motor is fixedly installed on the outer wall of the fixed seat. The output shaft of the motor is fixedly connected to one side of the climbing wheel.

[0013] Through the above technical solution, when the goods are at a high place, first cut off the power supply of the second electromagnet. At this time, the four-axis robotic arm can move out from the upper surface of the mobile robot. Then, the mechanical clamp clamps the two clamping rods on the column of the rack. At this time, the motor works to drive the climbing wheel to rotate, so as to drive the four-axis robotic arm and the mechanical clamp to move up along the column of the rack. When it moves to the required height, the four-axis robotic arm drives the second electromagnet at its lower end to closely adhere to the outer wall of the rack column and makes it energized and magnetically attracted, so as to move the robotic arm to a high place of the rack, facilitating the transfer operation of the goods at a high place.

[0014] In a preferred embodiment, electric Mecanum wheel sets are fixedly installed at the four corners of the bottom of the mobile robot.

[0015] In a preferred embodiment, a plurality of partitions are fixedly installed on the upper end of the mobile rack.

[0016] Through the above technical solution, by setting the partition board, the mobile rack can be divided into multiple different storage areas.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effect of the present utility model is: The present utility model provides a multi-objective flow shop scheduling device.

[0018] When the workload in the workshop is high, the mobile robot drives the mobile rack to move inside the workshop, and the four-axis robotic arm cooperates with the mechanical fixture to transfer the goods in the workshop, etc., greatly reducing the manpower requirement and the workload in the workshop. When the workload in the workshop is low, the mobile robot enters the storage bin, and the electric telescopic rod extends to make the first electromagnet at its end magnetize the mobile robot, fixing it inside the storage bin. At this time, the mobile rack can be fixed to serve as a shelf, providing a function even when not working. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] An electric telescopic rod 3 is fixedly installed at the inner top of the storage bin 2. A first electromagnet 4 is fixedly installed at the end of the output shaft of the electric telescopic rod 3. When the workshop workload is relatively low, the mobile robot 5 enters the interior of the storage bin 2. The electric telescopic rod 3 extends to magnetically attract the mobile robot 5 with the first battery iron 4 at its end, fixing it inside the storage bin 2. At this time, the mobile rack 1 can be fixedly used as the function of a shelf, enabling it to provide a role even when not working;

[0029] A mobile robot 5, with a traction chain 6 fixedly installed on the outer wall of its rear side.
