Brief description
Fig. 1 is the structural representation of this device.
Specific embodiment
As shown in figure 1, present invention is disclosed a kind of laser detector, including substrate 2, being arranged at the rotation on substrate 2
Mechanism and the testing agency being placed in rotating mechanism outer ring.In order to preferably standard, described rotating mechanism be carried out to product after detection
Top be additionally provided with a mark mechanism.
Specifically, described rotating mechanism includes being placed in the rotary cylinder 1 of substrate 2 lower section, and is placed in by cylinder axis 6 connection
Product rack on substrate 2.Described rack includes a pedestal 4, and the cylinder axis 6 of described rotary cylinder 1 connect pedestal 4, and
Moving base 4 can be carried to rotate.It is provided with one for clamping the fixture 8 of product to be detected in described pedestal 4；In order to fixation is treated further
Detection product, described pedestal 4 is further fixed on a magnetic force block 10, the upper end of described magnetic force block 10 wears out fixture 7 center and treats
The bottom magnetic force of detection product 5 connects.
Described testing agency includes a fixed seat 8 being placed on substrate 2, and described rack is enclosed and is located at by described fixed seat 8
Center.Relatively it is embedded with least one set laser head slider 3 in described fixed seat 8, described laser head slider 3 offers laser and leads to
Hole.Change laser head slider 3 for convenience, described laser head slider 3 is by connecting and fixing with the draw-in groove that opens up in fixed seat 3.
Meanwhile, in order to quickly check, three groups of laser head sliders 3 are typically relatively set with fixed seat 8, group number can be according to actual need
Set.Described laser via carries out upper, middle and lower on laser slide block and is uniformly distributed, and each described laser slide block sets
It is equipped with 3 laser via.Because the hole 61 on product 5 to be detected has because abrasive material is in different positions, if single will swash
Light through hole is arranged on the same line, then can lead to detection error due to the difference of test position.Therefore carried out using upper, middle and lower
It is distributed the accuracy it can be ensured that detecting.Certainly, each laser via line of upper, middle and lower is required in product to be detected relatively
In the hole 61 of product 5.
On the same axis, laser through laser via and penetrates in hole 61 in described laser via and product 5 to be detected
Hole 61 on product 5 to be detected is to detect whether hole blocks.If can pass through, represent that hole 61 is unplugged.If can not pass through,
Then represent that hole 61 blocks.
To after detection, whether qualified product carries out follow-up resolution for convenience, and described mark mechanism is by upper and lower air cylinders
11 and the inspection pen 9 that is connected with cylinder form.Described inspection pen 9 drives it to be moved by the work of upper and lower air cylinders 11, from
And be labeled on product after sensing.
Described detection means includes a PLC and alarm, and described PLC includes counting module, described
PLC is electrically connected with testing agency.Described alarm is electrically connected with PLC.
Due to testing different products, on product, the height in hole differs, and now needs to adjust the position that laser head slider is located
Put, for more rapid convenient adjusting position, described laser head slider is provided with one for accurately adjusting its upper-lower position
Governor motion, described governor motion includes turbine and worm screw, and one end of described worm screw connects laser head slider, wears in described turbine
If fixing a rotary shaft, rotating rotary shaft and driving turbine rotation, thus driving worm screw to be moved up and down, adjusting laser head slider
Position.
In order to further control the position of described laser head slider, strengthen the accuracy of its control simultaneously and increase this
Automatization's performance of device, described rack is provided with gravity sensor, described gravity sensor and described governor motion with
All by being electrically connected between PLC, the signal output part of described gravity sensor is with PLC signal input part even
Connect, the signal output part of described PLC is connected with the signal input part of governor motion.
The process that its automatization lower described briefly below is adjusted, the detection in the present invention is related to two kinds of different products, different
Product quality different, and on the product of different quality hole position different.For example, the A product being related in the present invention and B produce
Product, in location of C, in D position, when A product is placed on rack, gravity sensor detects the hole position of B product the hole position of A product
To its weight, transmit a signal to PLC, after PLC receives signal, transmit a signal to regulation machine through analysis
Structure, governor motion automatically adjusts after receiving signal, and laser head slider is adjusted to cap slider position；In the same manner, if adopting
Use B product, then laser head slider will be adjusted to lower position by adjustment structure.
In above example, illustrate just for above in the upper and lower limit position of laser head slider, alternatively upper limit position pin
To B product, lower position is directed to A product.
The detection method of the laser detector of the lower present invention described briefly below, comprises the steps,
S1, pre-detection step, product to be detected is positioned in the rack of rotating mechanism, by the magnetic force block of rack
Carry out magnetic force to fix, and fixed by the reinforcement that fixture carries out product to be detected；
S2, rotates detecting step, after S1 terminates, rotary cylinder band moving base is rotated, and meanwhile, laser sequentially passes through
The hole in laser via and product to be detected on the laser head slider of fixed seat side simultaneously enters into fixed seat opposite side laser
On slide block, laser via is detected, if can pass through then it represents that the hole on product to be detected is unplugged, if can not smoothly lead to
Cross the hole plug then it represents that on product to be detected, the enumerator in PLC carries out the note of hole number on product to be detected
Record；
S3, markers step, after rotation detection in S2, product is qualified, then PLC transmits a signal to above pedestal
Upper and lower air cylinders, upper and lower air cylinders drive inspection pen down on product, carry out qualified mark, if product is unqualified, check pen
It is not labeled；Meanwhile, PLC sends a signal to alarm, is reported to the police.
Certainly, the step product in above S3 is qualified and underproof mark may be reversed and carries out, i.e. qualified employing
Alarm equipment alarm, underproof employing checks pen mark.
All technical sides that the present invention still has numerous embodiments, all employing equivalents or equivalent transformation and formed
Case, is within the scope of the present invention.
