Description
Technical field
The invention proposes a kind of multistation based on AGV to inspect and return automatically production scheme by random samples, belongs to equipment production field, special
Shi Yongyu there be the automobile power assembly producing line of production capacity beat requirement.
Background technique
During equipment is manufactured, size, the accuracy of form and position etc. of workpiece are required higher and higher.In order to right
Workpiece size, the accuracy of form and position carry out efficient, stable measurement and control, efficient, stable sampling observation and return production scheme and seem especially
It is important.The equipment production line of traditional manufacture application, what is generallyd use is to inspect and return by hand production scheme by random samples.It is this by hand sampling observation and
Return production scheme have it is adaptable, tentatively put into low advantage, but its there is also following deficiencies: first is that not can guarantee it is efficient, stablize
Sampling observation and return production efficiency；Two are detrimental to the statistics of workpiece sensing result information, conclude, and fault trace difficulty is larger；Third is that
Need to put into a large amount of human costs for a long time, and higher to technical staff's skill requirement.
After searching and discovering the prior art, the prior art 1, Chinese invention patent " a kind of Wire harness quality detection method "
(application publication number CN102514768A) discloses a kind of Wire harness quality detection method.A kind of harness quality inspection of the disclosure of the invention
Test: survey method after checking that the conduction of harness, wire harness conducting test are qualified by tester, prints bar-code label；Entirely
Inspection: determine that the full-scale and appearance of harness prints appearance qualification mark after the full-scale and appearance of harness is qualified by drawing
Label, and appearance qualified label is pasted on harness；Sampling observation: the appearance qualified label printed in scanner scanning step B, control
It is qualified label that device processed, which determines this appearance qualified label, starts the bar-code label and appearance qualified label of examining harness later,
After qualification, harness enters next step；Packaging: scanning packing case bar code with scanner first, then scans harness with scanner
On bar-code label, controller determine this label be qualified label, packed.This method the problem is that, this method

Specific embodiment
The present invention is described in detail combined with specific embodiments below.Following embodiment will be helpful to the technology of this field
Personnel further understand the present invention, but the invention is not limited in any way.It should be pointed out that the ordinary skill of this field
For personnel, without departing from the inventive concept of the premise, several variations can also be made and changed.
The present invention solves method used by technical problem, and production side is inspected and return automatically to a kind of multistation based on AGV by random samples
Case.The program belongs to equipment production field, especially suitable for having the automobile power assembly producing line of production capacity beat requirement, including manufacture
Enterprise production process execute system (MES system), logistics carrying/Transmission system, AGV, information data module, multi-axis robot,
Casual inspection device, pallet, handgrip library, fixture database and safe-guard system.The program sends sampling observation instruction, logistics by MES system
Carrying/Transmission system is by workpiece to be checked and is transported to sampling observation roller-way, and AGV transports workpiece to inspecting website by random samples.Pass through information data mould
Block identifies workpiece type, and workpiece information is fed back to MES system.According to workpiece information, multi-axis robot is quick from clamping jaw library
Corresponding clamping jaw is chosen, composite measurement equipment replaces corresponding fixture automatically from fixture database and calls corresponding detection program.It has detected
It will test result logging data chip after and be sent to MES system, decide whether to return production further according to testing result, to realize
Production is inspected and returned automatically to multistation based on AGV by random samples.Safe-guard system is set, ensures the interaction of robot and composite measurement equipment
Safety.
As shown in FIG. 1 to FIG. 2, the present invention is based on the methods that production was inspected and returned automatically to the multistation of AGV by random samples, including following step
It is rapid:
Step 1: pickup.
The test point of corresponding different station 1, what MES system sent preparatory typing includes accordingly station 1, beat, workpiece
The sampling observation of type is instructed to truss robot/sliding rail articulated robot, and truss robot/sliding rail articulated robot replaces workpiece pair
After the handgrip answered by instruction from producing line grabbing workpiece and be transported to sampling observation roller-way it is to be checked.
Step 2: inspection.
MES system sends picking request to AGV monitoring management computer.AGV monitoring management computer is according to request scheduling
The AGV trolley of distance recently, idle inspects roller-way by random samples to corresponding.AGV takes cargo pallet away, send the sampling observation station to where casual inspection device
Point completes the transfer conveying of workpiece to be checked.
Step 3: detection.
Workpiece to be checked is sent to sampling observation website, utilizes the workpiece information in RFID technique automatic identification data chip.According to
Workpiece information selects corresponding detection device.By taking composite measurement equipment as an example, according to workpiece information multi-axis robot from handgrip library
Middle fast selecting corresponds to handgrip, and composite measurement equipment replaces corresponding fixture automatically from fixture database and calls corresponding detection program,
Subsequent manipulator quickly exchanges the pallet on the pallet and AGV in composite measurement equipment, and workpiece is fixed on comprehensive survey
Measure equipment suitable position.After composite measurement equipment is completed to the detection of workpiece to be checked, testing result is recorded in data chip
And it is sent to MES system.
Step 4: returning production and alarm.
The qualified workpiece of detection returns production automatically.Detection finishes, and as a result meets processing request, and MES system is to AGV monitoring management
Computer sends picking and returns production request, and AGV monitoring management computer recently, has just unsnatched the AGV of goods according to request scheduling distance
Trolley is to corresponding picking platform, and the pallet that multi-axis robot quickly will test on pallet and AGV in equipment is exchanged, AGV
Workpiece is sent to defined return and produces picking platform.MES system autocommand truss robot grasps at workpiece from production picking platform is returned
And it is transported to corresponding producing line, that completes workpiece returns production automatically.
It detects underproof workpiece warning reminding and scraps.Detection finishes, and does not as a result meet processing request, detection device hair
It alarms out, MES system sends picking to AGV monitoring management computer and scraps request, and AGV monitoring management computer is according to request
The AGV trolley that scheduling distance recently, just unsnatches goods quickly will test the pallet in equipment to picking platform, multi-axis robot is corresponded to
It is exchanged with the pallet on AGV, AGV, which send workpiece to defined, scraps picking platform.MES system autocommand multi-axis machine
Scrap workpieces are unloaded and send the return conveying for completing scrap workpieces to alignment processing station by people.
Specific embodiments of the present invention are described above.It is to be appreciated that the invention is not limited to above-mentioned
Particular implementation, those skilled in the art can make a variety of changes or modify within the scope of the claims, this not shadow
Ring substantive content of the invention.In the absence of conflict, the feature in embodiments herein and embodiment can any phase
Mutually combination.
