As shown in Figure 1, present invention is disclosed a kind of laser detector, comprise substrate 2, be arranged at the rotating mechanism on substrate 2 and be placed in the testing agency of rotating mechanism outer ring.In order to better carry out standard to product after detection, the top of described rotating mechanism is also provided with a mark mechanism.
Concrete, described rotating mechanism comprises the rotary cylinder 1 be placed in below substrate 2, and is connected the product rack be placed on substrate 2 by cylinder axis 6.Described rack comprises a pedestal 4, and the cylinder axis 6 of described rotary cylinder 1 connects pedestal 4, and moving base 4 can be with to rotate.One is provided with for clamping the fixture 8 of product to be detected in described pedestal 4; In order to fix product to be detected further, described pedestal 4 is also fixed with a magnetic force block 10, the upper end of described magnetic force block 10 wears out fixture 7 center and is connected with the bottom magnetic force of product 5 to be detected.
Described testing agency comprises one and is placed in holder 8 on substrate 2, and described rack is around in center by described holder 8.Described holder 8 is embedded with relatively at least one group of laser head slide block 3, described laser head slide block 3 offers laser via.Conveniently change laser head slide block 3, described laser head slide block 3 is by connecting and fixing with the draw-in groove offered on holder 3.Meanwhile, in order to check fast, generally on holder 8, be relatively set with three groups of laser head slide blocks 3, group number can set according to actual needs.Described laser via is carried out upper, middle and lower and is uniformly distributed on laser slide block, and each described laser slide block is provided with 3 laser via.Because the hole 61 on product 5 to be detected has because abrasive material is in different positions, if single laser via is arranged on the same line, then can, owing to detecting the difference of position, cause detecting error.Therefore adopt upper, middle and lower to distribute, the accuracy detected can be guaranteed.Certainly, each laser via in relative upper, middle and lower line all needs to drop in the hole 61 of product 5 to be detected.
Hole 61 on described laser via and product to be detected 5 on the same axis, laser through laser via and the hole 61 penetrated on product 5 to be detected whether block with detect aperture.If can pass through smoothly, represent that hole 61 does not block.If not by, then represent hole 61 block.
Conveniently to after detection, whether qualified product carries out follow-up resolution, described mark mechanism is made up of a upper and lower air cylinders 11 and the inspection pen 9 that is connected with cylinder.Described inspection pen 9 drives it to move by the work of upper and lower air cylinders 11, thus product after sensing marks.
Described pick-up unit includes a PLC and alarm, and described PLC comprises counting module, and described PLC and testing agency are electrically connected.Described alarm and PLC are electrically connected.
Owing to testing different products, on product, the height in hole differs, now need the position regulating laser head slide block place, in order to adjusting position more quickly and easily, described laser head slide block is provided with one for accurately regulating the governor motion of its upper-lower position, described governor motion comprises turbine and worm screw, one end of described worm screw connects laser head slide block, wear in described turbine and fix a turning axle, rotate turning axle and drive turbine rotation, thus drive worm screw to move up and down, regulate the position of laser head slide block.
In order to further control the position of described laser head slide block, strengthen its accuracy controlled simultaneously and increase the robotization performance of this device, described rack is provided with gravity sensor, described gravity sensor and between described governor motion and PLC all by being electrically connected, the signal output part of described gravity sensor is connected with PLC signal input part, and the signal output part of described PLC is connected with the signal input part of governor motion.
The below process of lower its robotization adjustment of summary, the detection in the present invention relates to two kinds of different products, and different product qualities is different, and on the product of different quality, the position in hole is different.Such as, the A product related in the present invention and B product, the hole of A product is positioned at C position, and the hole of B product is positioned at D position, when A product is placed on rack, gravity sensor detects its weight, by Signal transmissions to PLC, after PLC receives signal, by analysis by Signal transmissions to governor motion, governor motion automatically adjusts after receiving signal, and laser head slide block is adjusted to cap slider position; In like manner, according to B product, then laser head slide block will be adjusted to lower position by adjustment structure.
In above embodiment, the upper and lower limit position of laser head slide block is just for above citing, and also can be upper limit position for B product, lower position is for A product.
Below the detection method of the lower laser detector of the present invention of summary, comprises the steps,
S1, pre-detection step, is positioned in the rack of rotating mechanism by product to be detected, carries out magnetic force fix by the magnetic force block of rack, and is fixed by the reinforcement that fixture carries out product to be detected;
S2, rotate detecting step, after S1 terminates, rotary cylinder band moving base rotates, simultaneously, laser enters into laser via on holder opposite side laser slide block detect through the laser via on the laser head slide block of holder side and hole on product to be detected successively, if can pass through smoothly, then represent that the hole on product to be detected does not block, if can not pass through smoothly, then represent the hole plug on product to be detected, the counter in PLC carries out the record of hole number on product to be detected;
S3, markers step, after rotating in S2 and detecting, product is qualified, then signal is sent to the upper and lower air cylinders above pedestal by PLC, and upper and lower air cylinders drives inspection pen down on product, to carry out qualified mark, if product is defective, then checks pen not mark; Meanwhile, signal is sent to alarm by PLC, reports to the police.
Certainly, the qualified and underproof mark of the step product in above S3 also can carry out on the contrary, namely qualified employing alarm equipment alarm, underproof employing inspection pen mark.
The present invention still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes formed, and all drops within protection scope of the present invention.
