Description

Technical Field

[0001] The invention belongs to the field of logistics automation, and in particular relates to an assembly production line logistics automation system. Background Art

[0002] The logistics system of the lean production line has the following characteristics: Work-in-progress in the lean production line needs to undergo multiple tests, a single millimeter wave product needs to undergo 5 performance tests during the entire production process, a single optical cabin product needs to undergo 2 (some need 3) infrared tests and laser tests during the entire production process, and work-in-progress needs to be frequently transferred between workshops. Production line employees need to participate in the process of work-in-progress, which affects their working hours. Building an AGV system connects the material flow nodes in various areas of the production line in series, realizes material flow through information and automation, reduces the distance of manual transfer by employees, and improves the efficiency of work-in-progress transfer. Summary of the invention

[0003] 1. Technical issues to be resolved

[0004] The technical problem to be solved by the present invention is how to provide an assembly production line logistics automation system to solve the problem of product accumulation in the past.

[0005] (II) Technical solution

[0006] In order to solve the above technical problems, the present invention proposes an assembly line logistics automation system, including: an AGV platform management system, an AGV vehicle body, a PCS scheduling system, and a ground navigation system;

[0007] The AGV platform management system is connected to the workshop production scheduling system, and generates control instructions based on the production process and real-time data information during the production process and sends them to the PCS scheduling system;

[0008] The PCS dispatching system generates the operation task dispatching instructions of the AGV body according to the control instructions, and controls multiple AGV bodies to work together to transport materials;

[0009] The AGV body is provided with an AGV trolley, which carries out material handling according to the dispatching instructions of the PCS dispatching system;

[0010] The ground navigation system is used to construct the operation area of ​​the AGV body and generate the operation path of the AGV body. The ground navigation system is provided with an infrared communication node. When the AGV car passes through or stops at the infrared communication node in the venue, the AGV body communicates with the PCS scheduling system through the infrared communication node and exchanges data with the PCS scheduling system;

[0011] When the AGV body receives the dispatch instruction from the PCS dispatch system, it goes to the designated location. Each infrared communication node on the ground navigation system communicates with the AGV body when it passes by. When the AGV body receives the same location as the dispatch instruction from the PCS dispatch system, it stops moving and moves the material boxes on the shelf to the body. After completing the material box picking operation, it feeds back to the PCS dispatch system and starts transporting materials. After arriving at the designated transportation point, it places the material boxes on the corresponding shelf, completes the pick-up and delivery task, feeds back the status to the PCS dispatch system, and stops waiting for the next instruction.

[0012] The AGV body includes: a frame, a pallet, a pull rope encoder, a charging plate, an infrared communication module, and an ultrasonic wave;

[0013] The frame is an L-shaped frame, a lifting bracket is provided on the front end of the vertical part of the frame, a pull rope is provided on the lifting bracket, a pull rope encoder is provided on the top, a support plate is provided at the bottom of the bracket, the support plate is configured to be movable in the horizontal and vertical directions, an ultrasonic material box detector is provided on one side of the support plate, and the infrared communication module and the charging module are fixed on the side panels of the frame.

[0014] Among them, when the AGV body receives the same point as the dispatching instruction of the PCS dispatching system, the ultrasonic material box detector performs ultrasonic material box detection. When it detects that the QR code on the material box is the same as the PCS dispatching system instruction, it starts to control the pallet to lift and retract, and move the material box on the shelf to the body to complete the pickup.

[0015] The assembly line logistics automation system is also provided with an AGV charging station for charging the AGV body.

[0016] Among them, when the AGV body power is less than the set value lower limit, a charging request is fed back to the PCS dispatching system. After receiving the request, the PCS dispatching sends the AGV charging station location information. The AGV body arrives at the AGV charging station based on the information. The AGV charging station sends a request to start charging to the PCS dispatching system. The PCS dispatching system issues a charging instruction, and the AGV starts charging. After reaching the set value upper limit, the charging ends and waits for transportation instructions.

[0017] The AGV platform management system and the PCS dispatching system are connected by wire and exchange data through an intermediate library or real-time messaging.

[0018] Among them, when the AGV body encounters an obstacle on the material transportation route, it stops and sends an alarm to the PCS scheduling system.

[0019] Among them, when the AGV body reaches the PCS command point and fails to identify the material box or an abnormal situation occurs during the pick-up and delivery process, an alarm will be fed back to the PCS dispatching system.

[0020] (III) Beneficial effects

[0021] The present invention proposes an assembly production line logistics automation system. In view of the previous problems of scattered layout and roundabout logistics, the production lines are integrated into the same floor through integrated layout and lean design, and the floor area is reduced from 1728 square meters to 1200 square meters, and the transportation distance is reduced from 2800 meters to 200 meters. The AGV vehicle with a liftable fork is used to replace manual handling, freeing up manpower and enabling on-demand transportation, thus solving the problem of work-in-progress accumulation in the past.

[0028] The AGV platform management system is connected to the workshop production scheduling system, and generates control instructions based on the production process and real-time data information during the production process and sends them to the PCS scheduling system;

[0029] The PCS dispatching system generates the operation task dispatching instructions of the AGV body according to the control instructions, and controls multiple AGV bodies to work together to transport materials;

[0030] The AGV body is provided with an AGV trolley, which carries out material handling according to the dispatching instructions of the PCS dispatching system;

[0031] The ground navigation system is used to construct the operation area of ​​the AGV body and generate the operation path of the AGV body. The ground navigation system is provided with an infrared communication node. When the AGV car passes through or stops at the infrared communication node in the venue, the AGV body communicates with the PCS scheduling system through the infrared communication node and exchanges data with the PCS scheduling system;

[0032] When the AGV body receives the dispatch instruction from the PCS dispatch system, it goes to the designated location. Each infrared communication node on the ground navigation system communicates with the AGV body when it passes by. When the AGV body receives the same location as the dispatch instruction from the PCS dispatch system, it stops moving and moves the material boxes on the shelf to the body. After completing the material box picking operation, it feeds back to the PCS dispatch system and starts transporting materials. After arriving at the designated transportation point, it places the material boxes on the corresponding shelf, completes the pick-up and delivery task, feeds back the status to the PCS dispatch system, and stops waiting for the next instruction.

[0033] The AGV body includes: a frame, a pallet, a pull rope encoder, a charging plate, an infrared communication module, and an ultrasonic wave;

[0034] The frame is an L-shaped frame, a lifting bracket is provided on the front end of the vertical part of the frame, a pull rope is provided on the lifting bracket, a pull rope encoder is provided on the top, a support plate is provided at the bottom of the bracket, the support plate is configured to be movable in the horizontal and vertical directions, an ultrasonic material box detector is provided on one side of the support plate, and the infrared communication module and the charging module are fixed on the side panels of the frame.

[0035] Among them, when the AGV body receives the same point as the dispatching instruction of the PCS dispatching system, the ultrasonic material box detector performs ultrasonic material box detection. When it detects that the QR code on the material box is the same as the PCS dispatching system instruction, it starts to control the pallet to lift and retract, and move the material box on the shelf to the body to complete the pickup.

[0036] The assembly line logistics automation system is also provided with an AGV charging station for charging the AGV body.

[0037] Among them, when the AGV body power is less than the set value lower limit, a charging request is fed back to the PCS dispatching system. After receiving the request, the PCS dispatching sends the AGV charging station location information. The AGV body arrives at the AGV charging station based on the information. The AGV charging station sends a request to start charging to the PCS dispatching system. The PCS dispatching system issues a charging instruction, and the AGV starts charging. After reaching the set value upper limit, the charging ends and waits for transportation instructions.

[0038] The AGV platform management system and the PCS dispatching system are connected by wire and exchange data through an intermediate library or real-time messaging.

[0039] Among them, when the AGV body encounters an obstacle on the material transportation route, it stops and sends an alarm to the PCS scheduling system.

[0040] Among them, when the AGV body reaches the PCS command point and fails to identify the material box or an abnormal situation occurs during the pick-up and delivery process, an alarm will be fed back to the PCS dispatching system.

[0041] Production equipment can be divided into three data interaction modes according to the different methods of exchanging data with the AGV platform management system: one is automatic information docking with production equipment, such as robots, automatic transmission lines, etc., which can communicate data with the PCS scheduling system in real time; the second is manual information docking, calling or releasing the AGV body through the call box (or handheld device) equipped at each workstation on site; the third is no response workstation, such as shelf storage location. This type of equipment does not need to interact with on-site equipment. After the AGV body completes the operation, it is considered that the data interaction with the production equipment is completed.

[0042] After the production task is issued, the PCS scheduling system breaks down the task into three types: automatic information docking with production equipment, manual information docking, and no response required workstation.

[0043] When the task is to automatically dock with production equipment, the PCS scheduling system exchanges data with the production equipment, and the PCS scheduling system informs the production equipment to prepare, and the production equipment returns ready for transportation; after receiving the instruction, the PCS scheduling system sends a transportation instruction to the AGV body through the infrared data communication module in a wired connection mode, starts feeding and transportation, and informs the production equipment of the transportation status; after the AGV body transportation is completed, it feedbacks the status to the PCS scheduling system and stops waiting for the next instruction; the PCS scheduling system notifies the production equipment that it can start production, and when the production is completed and needs to be transported to the next process, it informs the PCS scheduling system, and the PCS scheduling system exchanges data with the production equipment of the next process according to the process settings, repeats the process, and after the final process is completed, the PCS scheduling system reports the completion of the production task to the smart workshop production scheduling system.

[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
