Abstract

The invention discloses a high-flexibility production line multi-vehicle detection system. The high-flexibility production line multi-vehicle detection system is characterized by being provided with locating pins and a detection unit. The locating pins are distributed on the periphery of a windmill change unit change flange in an evenly-spaced mode, and any locating pin can be changed on a work position over the change flange through rotation of the change flange. Each locating pin is provided with a laser recognition separation blade, a laser displacement sensor is arranged on a sensor support, and the laser recognition separation blades and the laser displacement sensor form the detection unit. Different relative distances capable of being recognized by the laser displacement sensor are arranged between the laser recognition separation blades placed on different locating pins and the same laser displacement sensor. A non-contact method is adopted to recognize positions of clamp systems on vehicles at present, and then types of white vehicle bodies can be determined.

A kind of high flexibility production line multi-vehicle-type detection system

Technical field

The present invention relates to a kind of high flexibility production line to the detection recognition system of multi-vehicle-type, more particularly is the system that is applied on the automobile body-in-white high speed roller bed flexible trolley pipeline for a kind of detection and Identification of current production vehicle.

Background technology

Fast development along with automobile industry, it has been more and more automakers' active demand that any swinging cross of multi-platform multi-vehicle-type is produced, and wherein the high speed roller bed flexible trolley induction system of high beat, high flexibility is a kind of significant transportation mode that satisfies this demand.In high flexibility chassis induction system, carry out the chucking appliance system that vehicle switches and be mounted on the chassis, play a part to support fixedly body in white and along with the chassis conveying.Because chassis moves, so how identify the position of the chucking appliance system on the current chassis and then confirm that the body in white model is a critical technical matters by discontiguous mode, there is not at present the open report of correlation technique.

Summary of the invention

The present invention is for avoiding the existing weak point of above-mentioned prior art, a kind of high flexibility production line multi-vehicle-type detection system being provided, to realize adopting discontiguous mode to identify position and then the affirmation body in white model of the chucking appliance system on the current chassis.

The present invention is that the technical solution problem adopts following technical scheme:

The design feature of high flexibility production line multi-vehicle-type detection system of the present invention is:

Each register pin that setting is promoted by cylinder, described each register pin switches the periphery of flange at the windmill switch unit to be spacedly distributed, described switching flange can be around the revolution of its axis, arbitrary register pin by the rotation of switching flange can switch in be in switch flange directly over working position on;

Detecting unit is set, and is that laser identification catch is set respectively on described each register pin, at sensor stand laser displacement sensor is set, and consists of the laser detection unit with described laser identification catch and laser displacement sensor; Be in and have the different relative distance that to be identified by described laser displacement sensor between laser identification catch and the same laser displacement sensor on the different register pins.

The design feature of high flexibility production line multi-vehicle-type detection system of the present invention also is: described laser identification catch is set divides to be in corresponding to the clamped condition of workholder and open mode and clamp the position and open on the position, described clampings position is on the different height and positions with opening; Corresponding to described clamping position with open the residing differing heights in position, described laser displacement sensor is set to respectively clamp the position laser displacement sensor and opens a laser displacement sensor, consist of the clamped condition detecting unit to be in the laser identification catch that clamps on the position and to clamp the position laser displacement sensor, consist of an open mode detecting unit to be in the laser identification catch of opening on the position and to open a laser displacement sensor.

Compared with the prior art, beneficial effect of the present invention is embodied in:

1, the present invention utilizes laser displacement sensor to pass through each register pin place station is judged in the detection of different distance, judge each vehicle, be to identify the position of the chucking appliance system on the current chassis and then confirm the body in white model by discontiguous mode, it is simple in structure, practical, stability is high, cost is low.

2, the present invention utilizes laser identification catch to judge workholder status position on the position at various height corresponding to clamped condition and the open mode office of workholder, and mode is simple and reliable.

3, the present invention separates topworks with signal recognition system, has solved the difficult problem of signal wire winding when switch unit carries out the vehicle switching.

Description of drawings

Fig. 1 is structural representation of the present invention;

Fig. 2 is another view of the present invention;

Number in the figure: 1 first register pin, 2 second register pins, 3 the 3rd register pins, 4 the 4th register pins, 1a the first catch, 2a the second catch, 3a the 3rd catch, 4a the 4th catch, 10 switching flanges, 11 sensor stands, 12a clamp a position laser displacement sensor, 12b opens a laser displacement sensor.

Embodiment

Referring to Fig. 1 and Fig. 2, the version of high flexibility production line multi-vehicle-type detection system is in the present embodiment:

Each register pin that setting is promoted by cylinder, each register pin switches the periphery of flange 10 at the windmill switch unit to be spacedly distributed, switching flange 10 can be around its axis revolution, arbitrary register pin by the rotation of switching flange 10 can switch in be in switch flange 10 directly over working position on.

Detecting unit is set, and is that laser identification catch is set respectively on each register pin, at sensor stand 11 laser displacement sensor is set, and consists of the laser detection unit with laser identification catch and laser displacement sensor; Be in and have the different relative distance that to be identified by laser displacement sensor between laser identification catch and the same laser displacement sensor on the different register pins.

As depicted in figs. 1 and 2, laser identification catch is set divides to be in corresponding to the clamped condition of workholder and open mode and clamp the position and open on the position, clamp the position and open and be on the different height and positions; Corresponding to clamping the position and opening the residing differing heights in position, laser displacement sensor is set to respectively clamp position laser displacement sensor 12a and opens a laser displacement sensor 12b, consist of the clamped condition detecting unit to be in the laser identification catch that clamps on the position and to clamp position laser displacement sensor 12b, consist of an open mode detecting unit to be in the laser identification catch of opening on the position and to open a laser displacement sensor 12a.

As depicted in figs. 1 and 2, by 90 ° of intervals four register pins being set in the present embodiment on switching flange 10, is respectively the first register pin 1, the second register pin 2, the 3rd register pin 3 and the 4th register pin 4; The laser identification catch that correspondence is arranged on each register pin is respectively the first catch 1a, the second catch 2a, the 3rd catch 3a and the 4th catch 4a; To be set to different discernible distances in order making between each laser identification catch and the same laser displacement sensor, each laser to be set to identify the difformity that catch is.
