[0027] Example

[0028] In order to solve the problem that the shaft in the current technology cannot improve the efficiency of laser engraving, information code detection and appearance inspection after assembly, refer to Figure 1-Figure 3As shown, the present application discloses a laser engraving and detection line, including a belt conveyor 10 for conveying a turntable 20, a laser engraving mechanism 30 for performing laser engraving on the surface of a product, a code scanning detection mechanism 40 for detecting the laser engraved information code, and an appearance detection mechanism 50 for detecting the appearance of the product. The laser engraving mechanism 30, the code scanning detection mechanism 40 and the appearance detection mechanism 50 are sequentially arranged above the belt conveyor 10 along the conveying direction of the belt conveyor 10. The conveying end of the belt conveyor 10 is provided with a turntable recovery basket 60 for recovering the turntable 20. In a specific implementation, the turntable recovery basket 60 of the present application is tilted at the conveying end of the belt conveyor 10. During the specific operation, the operator places the turntable 20 equipped with several rotating shafts on the belt conveyor 10, and under the transportation of the belt conveyor 10, the rotating shafts in the transfer box are sequentially passed through the laser engraving mechanism 30 for information code laser engraving, passed through the code scanning and detection mechanism 40 for information code scanning and detection, and passed through the appearance detection mechanism 50 for appearance detection. After the rotating shaft has passed the appearance inspection, the operator or the designed robot can unload and package the product, and the turntable 20 will automatically fall into the turntable recovery basket 60 for automatic recycling.

[0029] refer to Figure 3 As shown, the surface of the central turntable 20 involved in the present application is provided with a plurality of slots 21 for placing the rotating shafts at equal intervals, and the side of the central turntable 20 is provided with a plurality of through holes 22 corresponding to the slots 21 at equal intervals.

[0030] In this embodiment, two first positioning blocks 70 are provided on both sides of the conveying starting end of the belt conveyor 10, two second positioning blocks 80 are provided on both sides of the belt conveyor 10 close to the code scanning detection mechanism 40, and two third positioning blocks 90 are provided on both sides of the conveying end of the belt conveyor 10. By arranging two first positioning blocks 70, two second positioning blocks 80 and two third positioning blocks 90 on both sides of the belt conveyor 10, the belt conveyor 10 can drive the turntable 20 to move along the set trajectory to avoid offset, thereby ensuring that the laser engraving mechanism 30, the code scanning detection mechanism 40 and the appearance detection mechanism 50 can accurately perform information code laser engraving, information code scanning detection and appearance detection, thereby improving the working accuracy of the entire process and having high use value.

[0031] Based on the previous embodiment, a first clamping cylinder 100 is provided in one of the first positioning blocks 70 of the present application. When the belt conveyor 10 drives the turntable 20 to move, the first clamping cylinder 100 will drive its piston rod to reciprocate and extend (as for how to ensure that the piston rod can be inserted into the through hole 22 every time, it is necessary for personnel in this technical field to control the running speed of the belt conveyor 10 and control the extension and retraction interval time of the piston rod of the first clamping cylinder 100 during specific implementation). When the piston rod of the first clamping cylinder 100 is inserted into each through hole 22 of the turntable 20, the turntable 20 will stay under the laser engraving mechanism 30. In this way, the laser engraving mechanism 30 can perform information code laser engraving on the rotating shaft in the corresponding slot 21.

[0032] Also based on the previous embodiment, the present application provides a group of opposing photoelectric sensors a110 on the two second positioning blocks 80. When the light emitted by the light emitter of a group of opposing photoelectric sensors a110 (known technology) passes through each through hole 22 of the turntable 20 and is received by the light receiver, it indicates that a slot 21 has reached the corresponding position. At this time, the code scanning detection mechanism 40 will scan and detect the information code on the rotating shaft of the slot 21.

[0033] Also based on the previous embodiment, the present application provides a group of opposing photoelectric sensors b120 on two third positioning blocks 90, wherein one of the third positioning blocks 90 is provided with a second clamping cylinder 130 on the front side of a group of opposing photoelectric sensors b120, and a clamping plate 140 is connected to the piston rod of the second clamping cylinder 130. When the light emitted by the light emitter of a group of opposing photoelectric sensors b120 (known technology) passes through the first through hole 22 of the turntable 20 and is received by the light receiver, the second clamping cylinder 130 will drive the clamping plate 140 to extend to clamp the turntable 20 until the rotating shafts in all the slots 21 are removed and reset again.

[0034] In order to realize the installation of the laser engraving mechanism 30, the code scanning detection mechanism 40 and the appearance detection mechanism 50, the laser engraving mechanism 30 of the present application includes a first bracket 31 and a laser engraving head 32. The first bracket 31 is arranged outside the belt conveyor 10 near the first positioning block 70, and the laser engraving head 32 is fixed on the first bracket 31 above the belt conveyor 10. When the rotating shaft in the middle turntable 20 is under the laser engraving head 32, the laser engraving mechanism 30 will laser engrave the information code on the rotating shaft.

[0035] The code scanning detection mechanism 40 includes a second bracket 41 and a code scanner 42. The second bracket 41 is located outside the belt conveyor 10 near the second positioning block 80. The code scanner 42 is fixed to the second bracket 41 above the belt conveyor 10. When the rotating shaft in the middle turntable 20 reaches below the code scanner 42, the code scanner 42 will scan and detect the information code engraved on the rotating shaft.

[0036] The appearance detection mechanism 50 includes a third bracket 51 and a CCD visual detection camera 52. The rear side of the second positioning block 80 of the third bracket 51 is arranged on the outside of the belt conveyor 10. The CCD visual detection camera 52 is fixed on the third bracket 51 above the belt conveyor 10. When the rotating shaft in the turntable 20 is below the CCD visual detection camera 52, the CCD visual detection camera 52 performs an appearance inspection on the rotating shaft. It should be noted here that the CCD visual camera of this application needs to take pictures continuously.
