Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of automobile painting and relates to an automatic glue feeding management system and method for unmanned vehicles. BACKGROUND

[0002] The present application patent relates to the field of automobile painting, in particular to a glue feeding system replacement operation in a sealing process. In the production and manufacturing process of a vehicle, weld sealing glue and bottom protection paint need to be sprayed on the vehicle bottom, and weld sealing glue and liquid damping material also need to be sprayed in the vehicle. The weld sealing glue plays a sealing and anti-corrosion role; the bottom protection paint plays a stone impact prevention effect; and the liquid damping material can avoid vehicle body resonance and play a noise reduction function. To achieve the above functions, at least four sets of glue feeding systems, including a vehicle bottom weld sealing system, a bottom protection system, a vehicle interior weld sealing system and a liquid damping system, need to be provided in the sealing section of the painting field. The function of the glue feeding system is to provide stable and reliable continuous sealing material for automatic stations and manual stations. Therefore, at least one set of glue feeding system glue pump needs to be provided with one set of standby glue pump to avoid production line downtime waiting caused by glue replacement, quality impact and economic loss.

[0003] The existing glue feeding system in the painting field is shown in Figure 1 When the glue barrel is replaced, the transportation mode of manual + forklift is adopted. Due to the obstruction of the line of sight and the restriction of the space between the glue replacement rooms, the forklift operator can only transport the glue barrel outside the glue feeding room, and the subsequent operations (such as replacing the glue barrel and emptying the air) are all completed by manual operation, which is labor-intensive. At the same time, if the material in the glue barrel is used up, the manual operation is not timely or not skilled, which may cause production line downtime or glue pump emptying (air enters the pipeline, causing poor spraying), thereby causing batch quality risk and economic loss. At the same time, only one person cannot realize the glue replacement requirement of multiple glue feeding systems. According to the production situation on site, a glue replacement team needs to be equipped for each production line, which causes waste of human resources. In addition, when multiple glue feeding pumps (the mainstream in the industry is pneumatic pump) are working, the noise generated by the pump body exceeds the human engineering bearing range.

[0004] In summary, the existing glue feeding system in the painting field has the disadvantages of high labor input, poor working environment and high quality risk. Therefore, it is necessary to invent a glue feeding system that can realize automatic glue replacement, thereby fundamentally solving the glue replacement problem in the painting field, which is also the development direction of the subsequent glue feeding system.

[0010] It should be noted that, in this document, relational terms such as first and second and the like can be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus.

[0011] To solve the above technical problems, the present application is realized by adopting the following technical scheme:

[0012] An unmanned vehicle automatic glue management system, comprising an automatic glue system stereoscopic warehouse storage area, an unmanned vehicle, and a central control system PLC;

[0013] The automatic glue system stereoscopic warehouse storage area is used for temporary storage or transfer of glue barrels.

[0014] The central control system PLC transmits signals to the unmanned vehicle.

[0015] The unmanned carrier vehicle can tow the rubber bucket to flow in the coating workshop.

[0016] Further, the rubber storage three-dimensional warehouse in the automatic rubber coating system is divided into four layers from 1 to 4, one layer has four storage positions, and there are 16 empty positions.

[0017] Further, the unmanned carrier vehicle is provided with electromagnetic or optical automatic guiding device, can travel according to the specified guiding path, and has safety protection and various transfer functions.

[0018] Further, the unmanned carrier vehicle is of a towing type.

[0019] An automatic rubber coating management method of the unmanned carrier vehicle comprises the following steps:

[0020] Firstly, new rubber is brought: the material manufacturer sends the rubber bucket to the designated position of the coating workshop logistics door by truck, installs a limiting tray at the designated position to temporarily store the incoming rubber bucket, and the unmanned carrier vehicle can tow the limiting tray to reciprocate in the logistics door and the rubber supply room.

[0021] Secondly, the rubber is stored: each empty position of the rubber storage three-dimensional warehouse is provided with an independent motor, the movement and start-stop of each empty position motor are controlled by the PLC of the central control system, and the turnover of the rubber bucket in the three-dimensional warehouse is ensured.

[0022] Thirdly, the rubber is replaced: the empty rubber bucket is transferred to the rubber storage three-dimensional warehouse, and when the online rubber bucket is empty, the empty rubber bucket is replaced with a full rubber bucket. The limiting switch on the rubber pump pressure plate triggers a signal input to the PLC of the central control system. The PLC of the central control system transmits a signal to the unmanned carrier vehicle, the unmanned carrier vehicle moves the rubber pump pressure plate, and the empty rubber bucket is towed back to the three-dimensional warehouse. The empty position motor is used to transport the empty rubber bucket to the elevator of the three-dimensional warehouse, and the empty rubber bucket is temporarily stored in the third and fourth layers of the three-dimensional warehouse, waiting for the material manufacturer to transport it.

[0023] The full rubber bucket is placed under the rubber pump, and when the elevator finishes transferring the empty bucket, the PLC of the central control system gives an input signal to the elevator and the three-dimensional warehouse roller bed to control the elevator to the corresponding rubber bucket. The rubber bucket is transferred to the first layer, and the unmanned carrier vehicle transfers the rubber bucket to the position below the rubber pump pressure plate to automatically place the full rubber bucket under the rubber pump pressure plate, completing the rubber coating.

[0024] Then, the empty bucket is returned: after the new rubber is delivered, the system defaults to return the empty bucket, the PLC of the central control system gives a signal to the conveyor and the three-dimensional warehouse roller bed to return the empty bucket to the first layer, and the unmanned carrier vehicle tows the empty rubber bucket to the incoming tray at the door of the coating workshop. The material manufacturer collects the empty rubber bucket and reuses it.

[0025] Further, the control of the central control system PLC includes the control of the roller bed motor of the stereoscopic warehouse, the control of the incoming barrel vision recognition system, the communication control of the unmanned carrier vehicle system and the stereoscopic warehouse, the communication control of the rubber pump pressure disc limiter, the control of various detection switches, the control of the stereoscopic warehouse elevator.

[0026] Further, the field operation box is arranged, and the field operation box is used for preventing errors in automatic control and is a substitute scheme when the rubber coating system cannot be automatically operated.

[0027] Further, the lifting operation of the rubber barrel is completed through the elevator, and the elevator is automatically controlled by the PLC electric control cabinet of the central control system.

[0028] Further, the field sensor is arranged, and the field sensor is used for detecting various types of signals in the field, including a position detection switch, a temperature detection switch and a vision recognition camera component.

[0029] Further, in the process of incoming new rubber, a two-dimensional code is pasted on the rubber barrel, which is used for identifying the type and quantity information of the incoming rubber, facilitating subsequent transportation and storage, and after the incoming rubber falls on the limiting tray, the unmanned carrier vehicle drags the rubber barrel to the stereoscopic warehouse for temporary storage.

[0039] The present application will be described in detail below in combination with the drawings:

[0040] The purpose of the present application is to solve the problems of high safety risk, high personnel investment, and high operation difficulty in the coating workshop, and to provide a solution for automatic glue changing of the unmanned delivery vehicle of the glue supply system in the automobile coating workshop. A new scheme for automatic glue changing of the glue supply system is given, which can run completely automatically, reducing the difficulty of personnel operation and safety risk; a new type of glue barrel storage scheme is proposed, i.e. three-dimensional storage of glue, which can maximize the storage of glue by reasonably configuring the space arrangement of empty barrels and full barrels, while taking into account the glue changing efficiency; the control scheme of the automatic glue changing system is disclosed, which can automatically control the system to run autonomously in the case of complete absence of people; the present application provides a new idea and solution for the storage and transportation of auxiliary materials in the automobile industry.

[0041] An automatic glue feeding management system of unmanned delivery vehicle, comprising an automatic glue feeding system three-dimensional storage area, an unmanned delivery vehicle, a central control system PLC, a limit switch on the glue pump pressure disc, an empty position motor, a three-dimensional library roller bed, a conveyor, a glue pump pressure disc, a main control cabinet, a field operation box, an actuator and a field sensor;

[0042] Figure 2The automatic glue feeding system three-dimensional storage area of the present application can be seen from the figure, which is divided into four layers from 1 to 4, one layer has four storage positions, and there are 16 empty positions in total. The lower first and second layers are used to store full glue barrels, and the upper third and fourth layers are used to store empty glue barrels.

[0043] The automatic glue feeding system three-dimensional storage area includes a limiting tray, a glue barrel, a three-dimensional warehouse, an elevator, and a material receiving tray.

[0044] The function of the elevator is to temporarily store or transfer the glue barrels through lifting.

[0045] Figure 3 The schematic diagram of the unmanned carrier vehicle can tow the glue barrel in the painting workshop. The unmanned carrier vehicle refers to a transport vehicle with automatic guiding devices such as electromagnetism or optics, which can travel along a specified guiding path, and has safety protection and various transfer functions. The unmanned carrier vehicle in the present application is of the towing type and is divided into two types according to the actual working field. One is a transfer unmanned carrier vehicle for transferring new glue and empty barrels in the factory building, and the other is a transfer unmanned carrier vehicle for feeding glue barrels and empty barrels in the glue feeding room. The two types of unmanned carrier vehicles have the same principle. During idle time, the unmanned carrier vehicle is stored in a charging parking space for charging.

[0046] Figure 4 The actual planning diagram of the automatic glue feeding system of the unmanned carrier vehicle in the painting workshop glue feeding room is shown. The glue feeding system includes a bottom protection system (3 glue barrels), a vehicle bottom weld seal system (3 glue barrels), a liquid damping system (2 glue barrels), and a fine sealing system (3 glue barrels). Except for the liquid damping system glue pump, which uses one for one backup, the remaining systems all use one for two backups.

[0047] The bottom protection system, the vehicle bottom weld seal system, and the liquid damping system are used for different parts of the sprayed vehicle body and different types of paint, and have similar structures, which are composed of glue barrels, glue pumps, pressure plates, circulating pipelines, etc.

[0048] The bottom protection system, the vehicle bottom weld seal system, and the liquid damping system are composed of the automatic glue feeding system three-dimensional storage area, the unmanned carrier vehicle, the central control system PLC, the limiting switch on the glue pump pressure plate, the empty position motor, the three-dimensional warehouse roller bed, the conveyor, the pressure plate, the main control cabinet, the field operation box, the actuator, and the field sensor, which are in an inclusive relationship.

[0049] The automatic glue feeding system working logic implementation can be divided into the following steps:

[0050] Firstly, the new glue is delivered by the material manufacturer through a truck to the designated position of the logistics door of the painting workshop, a limiting tray is installed at the designated position, and the limiting tray is used for temporarily storing the incoming glue barrel. Meanwhile, the unmanned carrier vehicle can tow the limiting tray to reciprocate in the logistics door and the glue supply room. A two-dimensional code is pasted on the glue barrel to identify the type and quantity information of the incoming glue, facilitating subsequent transportation and storage. After the incoming material falls on the limiting tray, the unmanned carrier vehicle pulls the glue barrel to the temporary storage of the vertical warehouse.

[0051] Secondly, the glue storage (buffer area) adopts the form of a vertical warehouse. The vertical warehouse has four layers, and each layer has four spaces. Considering the rationality of the strength distribution of the vertical warehouse, the first and second layers are used to store incoming glue barrels (full barrels), and the third and fourth layers are used to store used glue barrels (empty barrels). Each space of the vertical warehouse is equipped with an independent motor, and the movement and start-stop of each space motor are controlled by a PLC, thereby ensuring the turnover of the glue barrels in the vertical warehouse. The lifting operation of the glue barrel is completed by a lift, which is automatically controlled by a central control system electric control cabinet. The present application considers the actual situation of a factory, and the bottom two layers of each layer are used to store glue barrels of fixed glue types, and two vertical warehouses are built, which correspond to the four types of glue produced at present.

[0052] Thirdly, the process of replacing the glue. Step one is to transfer the empty glue barrel to the vertical warehouse. When the glue barrel on the online glue supply system is empty, the empty glue barrel needs to be replaced with a full glue barrel. The limit switch on the glue pump pressure plate triggers a signal input to the PLC of the central control system. The PLC transmits the signal to the unmanned carrier vehicle, which moves the glue pump pressure plate and pulls the empty glue barrel back to the vertical warehouse. Before the empty glue barrel is pulled back to the vertical warehouse, it is transported to the lift of the vertical warehouse by the space motor and temporarily stored in the third and fourth layers of the vertical warehouse, waiting for the material manufacturer to transfer it. Step two is to place the full glue barrel under the glue pump. After the lift transfers the empty barrel, the PLC gives an input signal to the lift and the vertical warehouse roller bed to control the lift to the corresponding glue barrel. The glue barrel is transferred to the first layer, and the unmanned carrier vehicle transfers the glue barrel to the position below the glue pump pressure plate to automatically place the full glue barrel under the glue pump pressure plate, completing the glue feeding.

[0053] Returning the empty barrel: after the new glue is delivered each time, the system defaults to return the empty barrel. The PLC gives a signal to the conveyor and the vertical warehouse roller bed to return the empty barrel to the first layer. The unmanned carrier vehicle pulls the empty glue barrel to the incoming tray at the door of the painting workshop, and the material manufacturer collects the empty glue barrel for reuse.

[0054] In addition to the components analyzed above, the unmanned carrier vehicle automatic gluing system further comprises a main control cabinet (MCP), an on-site operation box (OPB), an actuator (OP), and on-site sensors (SENSOR), and the like. The main control cabinet (MCP) is the control core of the unmanned carrier vehicle automatic gluing system, and contains the control of the roll bed motor of the stereoscopic warehouse, the control of the incoming and returned barrel visual recognition system, the communication control of the unmanned carrier vehicle system and the stereoscopic warehouse, the pressure disc limiter of the glue pump, and the control of various detection switches, the control of the stereoscopic warehouse elevator, and the like. The main control cabinet is the brain of the entire gluing system. The function of the on-site operation box (OPB) is to prevent errors in automatic control, and to provide a substitute solution when the gluing system cannot automatically run. The on-site operation box can manually control the automatic gluing system. The actuator (OP) is used to execute various operation commands of the main control cabinet, and the roll bed motor, the stereoscopic lifting motor, the position locking electromagnetic valve, and the position detection sensor all belong to the actuator. The on-site sensors (SENSOR) are used to detect various types of signals on site, and contain position detection switches, temperature detection switches, visual recognition cameras, and the like.

[0055] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any modification, equivalent replacement, and improvement within the technical range disclosed by the present application, and within the spirit and principles of the present application, should be covered within the protection scope of the present application. Meanwhile, the contents not described in detail in the specification all belong to the prior art known to those skilled in the art.
