Description
Technical field
The invention belongs to field of vehicle detection, and in particular to the detection method and device of a kind of vehicle appearance.
Background technique
PDI detection is that a pre-sales detection proves, be new car friendship Chinese herbaceous peony must by inspection.Because new car is from production
Factory, which reaches, experienced thousands of kilometers of transport road and parks for a long time at dealer, in order to guarantee the safety of new car to customer
Property and genuine performance, PDI check it is essential.Wherein, a PDI index to be detected is exactly outer surface and the vehicle to vehicle
The detection of interior trim, detection process are usually to take pictures respectively to outside vehicle and inside, judge whether appearance deposits by photo
In defect.
Existing appearance detection usually transmits vehicle by conveyer belt, and vehicle is sent at camera, mechanical arm is passed through
Pull the handle of car door by car door opening, camera can photograph interior photo, but in the prior art, conveyer belt is passing
When sending vehicle, tend not to the handle of vehicle being accurately directed at mechanical arm, once deviating, mechanical arm during exercise can
The surface for arriving vehicle can be scraped.
Summary of the invention
The purpose of the present invention is to provide a kind of detection devices of vehicle appearance, to solve conveyer belt when transmitting vehicle,
Tend not to the problem of handle of vehicle is accurately directed at mechanical arm.
In order to achieve the above objectives, base case of the invention are as follows: the detection device of vehicle appearance, including for transmitting vehicle
Conveyer belt and mechanical arm for pulling open car door, conveyor belt two sides be equipped with camera, mechanical arm includes pedestal and setting
Picking unit and positioning unit on pedestal, picking unit includes sliding laterally the crawl bar being connected on pedestal, on pedestal
It is further fixed on the cylinder for driving crawl bar sliding, is slid laterally on crawl bar and is connected with slide bar, is fixed on slide bar vertical
Connecting rod, the upper and lower ends of connecting rod are hinged with clamping jaw, and clamping jaw is equipped with strip groove, and protrusion, protrusion insertion are fixed on pedestal
Into strip groove；Positioning unit includes the locating rod being hinged on pedestal, and torsional spring, locating rod are equipped between locating rod and pedestal
It is fixed with sponge block close to one end of conveyer belt, positioning boom end is equipped with strip-shaped hole, and slide bar end is fixed with convex block, convex block insertion
In strip-shaped hole；It is located between locating rod and crawl bar on pedestal and is fixed with limited block, the junction of locating rod and sponge block is fixed
There is pressure sensor, pressure sensor is electrically connected with the controller for controlling conveyer belt opening and closing.
The working principle and beneficial effect of this base case are:
The original state of sponge block can be affixed with vehicular sideview, due to the side convex at vehicle handle compared to vehicle
It rises, therefore when the handle of vehicle and sponge block contact, vehicle continues to move, and handle just will drive sponge block deflection, due to sea
Continuous block has the surplus of contraction, therefore will not cause scratch to handle.Sponge block drives locating rod to deflect, in locating rod deflection process
Band moving slide-bar slides on crawl bar, and slide bar drives rod slide, and connecting rod drives two clamping jaws close to each other.By the limit of limited block
System, when locating rod and limited block offset, since locating rod can not continue to deflect, handle is expressed to pressure sensor, and pressure passes
Signal is passed to controller, conveyer belt stop motion by sensor.At this point, two clamping jaws also can be just caught in handle, clamp
Handle.
The setting of the application, when after handle and sponge block are in contact and squeezing sponge block, so that conveyer belt stop motion,
Handle more can be accurately made to rest at clamping jaw.And locating rod just drives jaw action while positioned
Handle is clamped, working efficiency is higher.
Further, what two clamping jaws were opposite is equipped with flexible layer on one side.
The utility model has the advantages that clamping jaw is avoided to be expressed to vehicle handle and damage to vehicle handle.

It answers, connecting rod includes vertical bar and cross bar, and vertical bar is connected to conveyer belt side, and cross bar is scalable, and brake block is fixed on cross bar, is made
The power supply that the lower end of motion block is fixed with electromagnet and is powered for electromagnet.
The utility model has the advantages that being rotatablely connected bar after in vehicle driving to conveyer belt, connecting rod drives brake block state in a vertical shape,
The bottom of brake block and transmission belt surface are affixed, and start electromagnet, and electromagnet attracts magnetic patch, and magnetic patch drives brake block in conveyer belt
Surface sliding, cross bar elongation can avoid vehicle and skid on a moving belt very so that brake block slides into the rear portion of vehicle rear wheel
To moving backward.
Connecting rod is rotatably connected on the side of conveyer belt, and it is flat that connecting rod can drive brake block to turn to and transmit belt surface
Row, when not needing using brake block, connecting rod does not interfere with the operation of conveyer belt
Further, the both ends of conveyer belt are provided with inclined guide table.
Conveyer belt is left the utility model has the advantages that facilitating in vehicle driving to conveyer belt or travelling.
The present invention also provides a kind of detection methods of vehicle appearance, comprising the following steps:
A, vehicle to be detected is travelled by guide table to conveyer belt, is rotatablely connected bar, connecting rod drives brake block
State in a vertical shape starts electromagnet when the bottom of brake block and transmission belt surface are affixed；
B, conveyer belt haulage vehicle forward, when at vehicle transport to camera, camera takes pictures to vehicle, passes through
The appearance of photo detection vehicle whether there is defect；
C, when original state, locating rod is in a horizontal state, and sponge block can be affixed with vehicle side wall, when vehicle transport to sea
When continuous block is affixed, the handle of vehicle pushes sponge block, and sponge block drives locating rod deflection, when handle is expressed to pressure sensor
When, pressure sensor gives controller pressure signal transmission, and controller controls conveyer belt stop motion；
D, during sliding bar, jaw action is driven to clamp handle, starts cylinder, cylinder driving crawl bar is to far from vehicle
The movement of direction, car door opening；
E, camera carries out pan-shot to car, completes detection.
Using detection method of the invention, it can solve conveyer belt when transmitting vehicle, tend not to the handle of vehicle
Accurately the problem of alignment mechanical arm.
