1. the feeding Y-direction moving assembly 174 drives the lifting table 171 to move to the outside of the protective cover, a product is placed on the lifting table 171, the X-direction limiting driver 1773 drives the X-direction limiting rod 1771 to move towards the direction approaching the first baffle 175, when the X-direction pressure sensor senses that the pressure of the X-direction limiting rod 1771 reaches a first set pressure, the X-direction limiting rod 1771 stops approaching the first baffle 175, and therefore the X-direction limiting rod 1771 is used for transversely limiting the product; the Y-direction limiting driver 1782 drives the Y-direction limiting rod 1781 to move towards the direction approaching the second baffle 176, and when the Y-direction pressure sensor senses that the pressure of the Y-direction limiting rod 1781 reaches the second set pressure, the Y-direction limiting rod 1781 stops approaching the second baffle 176, so that the product is longitudinally limited by the Y-direction limiting rod 1781; the feeding Y-direction moving assembly 174 drives the lifting table 171 to move to the inside of the protective cover;

2. rotating the adjusting nut 2052 so that the head of the adjusting nut 2052 is far away from the positioning strip 204, moving the connecting strip 2051 to a proper position, and then reversely rotating the adjusting nut 2052 so that the head of the adjusting nut 2052 is abutted against the positioning strip 204, thereby fixing the connecting strip 2051 and enabling the interval between the two groups of feeding sucking discs 201 to be matched with a product;

3. the feeding Y-direction driver 202 drives the feeding sucker 201 to move downwards to suck up the product, then the feeding Y-direction driver 202 drives the feeding sucker 201 to move upwards, at the moment, other products can be adhered to the lower part of the product sucked up by the feeding sucker 201, and the lower part of the product can be brushed down through the brush 179; the feeding X-direction driver drives the feeding manipulator 20 to place the product on the conveying table 14;

4. the conveying Y-direction moving assembly 15 drives the two conveying tables 14 to move from the upper material level to the lower material level to the detection position sequentially, the positioning camera 12 determines the marking position, then the two conveying tables 14 move to the marking position sequentially, the laser 13 is used for marking products, then the two conveying tables 14 move to the overturning position sequentially, the clamp 161 clamps the products on the conveying tables 14, the rotary Z-direction driver 163 drives the clamp 161 to move upwards, the rotary driver 162 drives the clamp 161 to overturn by 180 degrees, the rotary Z-direction driver 163 drives the clamp 161 to move downwards, and the products are put back onto the conveying tables 14; then, the two conveying tables 14 are moved to marking positions in sequence, and the laser 13 marks the other surface of the product; finally, the two conveying tables 14 are moved to the upper and lower material levels in sequence;

5. the blanking manipulator 21 carries the qualified products after marking from the conveying table 14 to the discharging device 18, carries the problematic products to the NG platform, and carries the products with uncertainty whether the problematic products are to be carried to the manual detection platform.

This is the working process of the automatic detection laser marking machine of the preferred embodiment.

The automatic detection laser marking machine comprises two conveying tables, wherein the two conveying tables are sequentially positioned at the upper material level and the lower material level, the products are respectively fed, the two products are sequentially conveyed to a detection position and a marking position respectively, the marking position is determined through a positioning camera, the products are marked through a laser, and finally the two conveying tables sequentially return to the upper material level and the lower material level, the products are respectively fed, and the products are respectively fed again. According to the automatic detection laser marking machine, when one conveying table conveys a product to the position below a laser for marking, the other conveying table can be used for blanking and reloading, and after the product marking on the former conveying table is finished, the product on the other conveying table can be marked later, so that the production efficiency is effectively improved.
