Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The invention provides a drive device preassembling method and device, aiming at the problem that in the prior art, in a finished automobile assembly production line, drive device preassembling cannot realize automation and intellectualization.
As shown in fig. 1, an embodiment of the present invention provides a method for preassembling a driving apparatus, the driving apparatus being applied to an excavator, the method including:
s101: and determining the preassembly required time of the driving device according to the assembling required rhythm of the whole excavator.
The drive device is applied to an excavator. Taking 3 whole car assembly lines as an example, the takt time of each whole car assembly line is 18min, 18min and 45min, and under the condition that each car is provided with two driving devices, the production takt time of the assembly line is calculated to be 3.5 min.
S102: and controlling the pre-assembly processes of the driving device, such as loading, cleaning, drying, screwing in the bolt, torque operation and unloading, to be automatically performed in sequence on a pre-assembly production line within the required time, so as to complete the pre-assembly of the driving device.
It should be noted that, in the prior art, the cleaning process needs to be performed manually, and the cleaning area is separated from the pre-assembly area, so that the cleaning operation is environmentally poor, the labor intensity is high, in order to realize the automation of the whole pre-assembly production line, the cleaning and pre-assembly processes are centralized within the required time, and the streamline and automation of the cleaning and pre-assembly are realized.
The production process flow is as follows:
upper part → cleaning → drying → screwing in bolt → torque operation → part unloading.
The drive device at least comprises: a motor and a sprocket.
The process of automatically executing the pre-assembly of the driving device on the pre-assembly production line sequentially comprises the following steps of loading, cleaning, drying, screwing in bolts, torque operation and unloading:
conveying the motor and the chain wheel to a cleaning table by using a mechanical arm and a conveying belt, and simultaneously cleaning and drying the motor and the chain wheel on the cleaning table;
the cleaned motor is turned over according to a preset angle, the turned motor is conveyed to an assembly table by a truss servo mechanism for positioning, and then a vision system is adopted for positioning and assembling the chain wheel;
adopting automatic bolt arraying equipment, a robot and a bolt tightening device to tighten the motor and the chain wheel;
removing the tightened motor and sprocket from the mounting station.
It should be noted that, the preassembly production process mainly includes: 1. loading the motor and the chain wheel to a cleaning table by using a manipulator and a conveyor belt, and performing coarse positioning; 2. cleaning and drying the motor and the chain wheel on a cleaning table; 3. the motor is turned 180 degrees by using a truss servo mechanism, the turned motor is conveyed to an assembly table, the motor is clamped and positioned by using a hydraulic or servo electric cylinder, a chain wheel is grabbed, and the chain wheel is placed on the assembly table and is positioned and pre-assembled; 4. adopting automatic bolt arraying equipment, a robot and a bolt tightening device, tightening a motor and a chain wheel by using bolts, and completing torque operation; 5. unloading the screwed motor and the chain wheel from the assembly table by using a manipulator; 6. the tightened motor and sprocket are delivered to the entire Vehicle assembly line using an Automated Guided Vehicle (AGV).
Since the weight of the motor and the chain wheel are both between 100 and 600Kg, the cost of using the robot is increased, and the truss servo mechanism is selected to transport the motor and the chain wheel to the assembly station and to unload the tightened motor and the chain wheel from the assembly station in consideration of the simpler action and route.
In this embodiment, the manipulator used for assembling and disassembling the parts has five degrees of freedom, including: the functions of servo translation and positioning in the X/Y/Z three directions and rotation in the Y/Z two directions.
During the assembly of the sprocket with the motor, a visual communication system is used to align the holes and centers the sprocket in comparison to a reference.
When unloading, various universal trays are designed, and the traction part of the AGV is reserved.
The simultaneously washing and drying the motor and the sprocket on the washing table comprises:
cleaning the motor and the chain wheel at a medium pressure fixed point by using a cleaning agent;
rotating and cleaning the contact surface of the motor by adopting a clamping tool, brushing the threaded hole of the motor and rotating and cleaning the threaded hole at the same time;
cleaning two end faces of the chain wheel, and brushing and cleaning the middle through hole of the chain wheel;
and drying the cleaned motor and the cleaned chain wheel by using compressed air.
The cleaning aims to clean oil stains, corrosion inhibitors, scrap iron and other substances on the surfaces of the motor and the chain wheel, and the moment attenuation of the bolt is avoided. In the cleaning process, the used cleaning agent can be a water-soluble cleaning agent or a solvent-type cleaning agent, and the water-soluble cleaning agent is more environment-friendly and has low cost. .
The motor mainly comprises two contact surfaces and two layers of threaded holes which need to be cleaned, and in order to clean thoroughly, the embodiment of the invention adopts a four-axis clamp or a mechanical arm to clean the contact surfaces, uses a brush for the threaded holes, and cleans the threaded holes in a manner of rotating and cleaning. The two end faces of the chain wheel are washed by the spray heads, the middle through hole is also washed by the brush in a rotating and cleaning mode. After cleaning, the fabric is dried by compressed air, and normal-temperature air or warm air can be used. Preferably, in the embodiment, the drying is carried out by using warm air at 30-40 ℃.
Before the motor and the chain wheel are screwed, the method further comprises the following steps:
determining the specification type of the mounting bolts and the use information of the use number produced on the day;
and determining the dimension and the beat of the automatic bolt alignment equipment according to the use information.
It should be noted that the number of bolts required to assemble different types of motors and sprockets varies from 12 to 36, and therefore the labor intensity of manually screwing and pre-screwing the bolts in takt time is very high. In order to realize the automatic arrangement of the bolts, the addition of gaskets, the smearing of bolt glue and the automatic screwing and screwing of the bolts, the automatic arrangement equipment of the bolts is adopted, and the automation of the bolt screwing is realized by combining a robot and a bolt screwing device. The automatic bolt arraying equipment can realize the sharing of bolts with multiple specifications. Before the bolts are screwed, the type of the bolts to be installed and the production and use number on the day need to be determined, the size specification of the automatic bolt arraying equipment can be determined according to the type of the bolts to be installed and the production and use number on the day, and the number of the bolts and the gaskets to be input before the start of daily work can be determined according to the type of the bolts to be installed and the production and use number on the day.
The kinds of mounting bolts and the number of production uses on the day are shown in table 1 below.
TABLE 1 bolt kinds and usage amount table
In order to avoid the wrong screwing of the bolt into the screw thread, a closed loop system needs to be established on three factors of screwing speed, distance and moment.
Since the manipulator is responsible for loading and unloading, the operation logic of the manipulator in the required time is arranged and distinguished, as shown in fig. 2, the logical time relationship of loading and unloading of the manipulator and the transportation of the AGV is as follows:
taking the required time as 3.5min as an example, the unloading is completed within the first 60 seconds, the loading of the motor and the chain wheel and the combined positioning work are completed within the time of 60 seconds to 210 seconds, the loading of the motor is started at 60 seconds, the loading of the chain wheel is started at 121 seconds, the combined positioning of the motor and the chain wheel is performed at 141 seconds, then the standby is performed at 171 seconds until the required time 210 seconds, the rotation of the rotary table is started, and the process is continuously circulated.
S103: and conveying the pre-assembled driving device to a whole vehicle assembly production line.
The assembled drive device is transported to a vehicle assembly line by an AGV vehicle.
The method further comprises the following steps:
automated export of pre-assembled production plans.
In order to realize the intelligentization of the production line, it is necessary to construct an intelligent production line for pre-assembly and to effectively interface the pre-assembly production line with the entire vehicle assembly production line.
Before the automated deriving of the pre-assembled production plan, the method further comprises:
determining the number of bits of the mounting process of the driving device on the whole vehicle assembly production line;
and according to the digit difference between the first procedure of the whole vehicle assembly production line and the digit of the installation procedure, the station beat time difference and the actual production input, formulating the pre-assembled production plan.
It should be noted that, for the single-line production mode, the production plan of the preassembly line is the lead of the assembly production plan of the whole vehicle, and automation is relatively easy to implement. However, in the actual production, there may be several complete vehicle assembly lines supplied from a pre-assembly line, which involves the time and amount of labor involved, and it is difficult to automatically arrange the production plan.
In the existing production, the installation of the pre-assembled driving device is generally set to be carried out in 4/5 th procedure of a whole vehicle assembly production line, so that the pre-assembled production plan can be made according to the policy, the first procedure of the assembly, the procedure number difference between the procedure of the installation of the driving device and the actual production input, and the accuracy of the pre-assembled production plan can be ensured.
As shown in fig. 3, the tact time of the entire vehicle assembly line is 18min, and the installation of the pre-assembled driving device is set to be performed in the 4 th step of the entire vehicle assembly line, so the pre-assembled production plan is analyzed as follows:
the takt time of the whole vehicle assembly line is 18min, the installation of the pre-assembled driving device is set to be carried out in the 4 th procedure of the whole vehicle assembly line, the middle pre-assembly available time is 4 × 18 to 72min, the pre-assembly cycle takt time is 3.5min, and 8 procedures in total can be calculated, the pre-assembly time is 3.5min × 8 to 28min, the time difference between the two is 44min, namely the time for forklift spare parts, driving device hoisting, pre-assembling in-process and AGV vehicle transportation, and the pre-assembling can be realized in the actual production operation.
If special conditions are met, the takt time of the pre-assembly production line is 3.5min, the takt time except the time for transporting the forklift spare parts and the AGV car within 44min can be reflected on the workload, the workload can be overstocked, at the moment, a time variable x can be added to the whole vehicle assembly production input time t, and the pre-assembly available time can be shortened by 72 min. Wherein the time variable x is related to the actual operating situation.
In the spare part process, whether the input product is consistent with the production plan or not is confirmed, and if so, the preassembly production line starts to produce.
After the pre-assembly production plan is made, a step of confirming whether the input product matches the production plan or not is added to the forklift spare part process which is the first process, and the step may be confirmed by an operator, by scanning a component identification code, by comparing the shape of the component with a database, or the like.
Acquiring relevant production information in the pre-assembly process of loading, cleaning, drying, screwing in bolts, torque operation and unloading, and transmitting the production information to a corresponding process of the pre-assembly production line.

the automatic guided vehicle AGV comprises external dimension information and hole number information of a cleaning workpiece in the cleaning process, workpiece external dimension information and grabbing point information which are acquired by a truss servo mechanism, and unloading information which is transmitted to the automatic guided vehicle AGV in the unloading process.
It should be noted that, along with the intelligentization of the production line, the production information related to the pre-assembled loading, cleaning, drying, screwing in the bolt, torque operation and unloading process is transmitted to each process along with the production, wherein the production information may be the external dimension information and the hole number information of the cleaned workpiece in the cleaning process, or the external dimension information and the grabbing point information of the workpiece acquired by the servo mechanism, and the unloading information transmitted to the automatic guided vehicle AGV in the unloading process.
The method further comprises the following steps:
controlling the whole vehicle production processes in the whole vehicle assembly production line to transmit information in an information sharing and pulling mode;
wherein, whole car production flow includes: spare part flow, product input flow, preassembly flow, finished product in-process flow and finished vehicle assembly flow.
It should be noted that, the production process of the whole vehicle assembly also needs to realize the information transmission of the whole process, that is, the information transmission is performed from the material preparation of the forklift to the pre-assembly, and the information transmission is performed on the requirement information of the finished product of the driving device on the production line of the whole vehicle assembly, at this time, the information transmission can be performed in the manner of information sharing and pulling, and the information sharing and pulling of the whole process are performed, so that a plurality of systems and hardware can be used, most commonly, a safety light system and a vehicle-mounted navigation device are used, and in the subsequent production process, the resource integration of the safety light system or the vehicle-mounted navigation device and other parts can be performed, so as to realize the function of one system or one device.
By adopting the embodiment, the automation of the pre-assembly production process can be realized by 75% at most, the time of the whole vehicle assembly production line is reduced by 20min, the beat limiting procedure is eliminated, the fund is saved, and the labor intensity of operators is reduced.
