[0033] The laser marking device 4 includes a marking positioning conveyor line 48, a support frame 43 for support is arranged in front of the marking positioning conveyor line 48, and a laser marking machine 41 is fixedly arranged at the center of the top surface of the support frame 43, a pre-clamping cylinder 44 is arranged in front of the support frame 43, a smoking pipe 42 is arranged near the side of the lower end surface of the support frame 43, and three groups of marking blocking cylinders 47 are equidistantly arranged at the rear of the lower wall of the support frame 43 opposite to the laser marking machine 41, two groups of opposite second positioning clamping cylinders 45 are arranged between the pre-clamping cylinder 44 and the marking blocking cylinder 47, and three groups of second incoming material sensors 46 are equidistantly arranged between the second positioning clamping cylinder 45 and the marking blocking cylinder 47.

[0034] The three groups of industrial cameras 22, the material dividing and blocking cylinder 24, the first incoming material sensor 25 and the incoming material blocking cylinder 29 are all located on the same straight line, which can effectively improve the accuracy of subsequent material monitoring and the stability of guidance.

[0035] The rear opening of the qualified product slide 51 is directly opposite to the rear of the visual positioning conveyor line 27, which can effectively improve the accuracy of the subsequent export of the inspected materials.

[0036] The docking slide 55 is slidably engaged with the interior of the waste transition box 54, which can facilitate the subsequent lifting of the fixed base 52 by the guide cylinder 53, so that the docking slide 55 is directly opposite to the visual positioning conveyor line 27, which is convenient for the subsequent export of materials that have not passed the inspection.

[0037] Working principle: When marking the reagent plate, the external feeding module can position the reagent plate to the upper part of the loading and positioning conveyor line 3. When feeding the reagent plate, the incoming materials on the upper part of the loading and positioning conveyor line 3 are arranged in sequence, and at the same time, the three material channels of the loading and positioning conveyor line 3 are all in a state of having materials;

[0038] When the reagent plate to be marked is delivered to the laser marking device 4, the three groups of marking blocking cylinders 47 are in the blocking position by default. When the second incoming material sensor 46 senses the material, the second positioning clamping cylinder 45 clamps the product, and the pre-clamping cylinder 44 clamps the rear product to prevent the subsequent product from affecting the product being marked. Then marking begins. When marking is completed, the marking blocking cylinder 47 rises, the second positioning clamping cylinder 45 is released, the product flows away, and the smoke generated by marking is sucked away by the external dust collector through the smoking pipe 42;

[0039] When the real-time marked product flows away, and the second incoming sensor 46 cannot detect the product, the marking blocking cylinder 47 descends, and the pre-clamping cylinder 44 is released, and the rear product comes in, and an action cycle ends;

[0040] Since the above-mentioned marking materials are transmitted by the loading positioning conveyor line 3 and the marking positioning conveyor line 48, the three lanes must have materials at the same time. When marking, the first lane is used as the starting point of the cycle. After marking the product code of the first lane, the second lane product code is started. After marking the product code of the second lane, the third lane code is marked. The marking of three products is considered a cycle. In the above-mentioned marking steps, when the product code of each lane is marked, the lane is immediately released, and the laser codes the next lane. The released lane is ready for the next cycle of coding products, that is, the laser coding is continuous and does not stop.

[0041] When the material feeding detection is performed, the conveying speed of the marking positioning conveyor line 48 is slow, while the conveying speed of the visual positioning conveyor line 27 is fast. The incoming materials are divided by using the speed difference between the belts. The gaps caused by the speed difference are blocked by the descending material dividing and blocking cylinder 24. As long as the material feeding sensor 210 cannot detect the material, the material dividing and blocking cylinder 24 descends to the blocking position.

[0042] By default, the incoming material blocking cylinder 29 is in the descending blocking position. When the first incoming material sensor 25 senses the material, the first positioning clamping cylinder 26 clamps the product, and the industrial camera 22 starts to detect. When the detection is completed, the incoming material blocking cylinder 29 rises, and the first positioning clamping cylinder 26 releases. When the first incoming material sensor 25 cannot detect the material, the incoming material blocking cylinder 29 descends;

[0043] At the same time, when testing, the clamping and testing mechanisms of the three lanes are independent of each other, that is, when the material is coming in, the test will not affect each other. At the same time, the industrial camera 22 saves and records the test data for subsequent query;

[0044] When unloading, if the visual inspection device 2 detects qualified, the material falls directly into the material conveying belt through the qualified product slide 51. If the visual inspection device 2 detects unqualified, the guide cylinder 53 rises directly, and the material falls directly through the fixed holder 52 and the waste transition box 54 for collection. When the photoelectric switch 28 detects the material delay, the guide cylinder 53 descends. At the same time, during the inspection, the three guide cylinders 53 of the three material channels are independent of each other and do not affect each other, so qualified products are distinguished from unqualified products.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
