[0050] See also Figure 1 The laser engraving detection equipment provided in this embodiment includes a transmission device 1, a laser engraving machine 2, and a visual detection device 3.

[0051] The transmission device 1 is used to transport the transport vehicle 100 loaded with electronic cigarettes. The laser engraving machine 2 is located at the upstream position of the transmission device 1 and is used to perform laser engraving operations on the electronic cigarettes in the transport vehicle 100.

[0052] See also Figure 2 The visual inspection device 3 is located downstream of the transmission device 1, and includes a CCD module 301 for visually inspecting laser-engraved images and texts on the electronic cigarette, an NG recovery storage rack 302 for recycling electronic cigarettes that fail laser engraving, a replenishment supply rack 303 for providing electronic cigarettes that have passed laser engraving, and a shifting robot 304 for shifting the electronic cigarette.

[0053] It should be noted that the laser engraving machine 2 used in this embodiment is an existing product on the market, and its specific structure and working principle are not the focus of the present utility model, so they are not described in detail.

[0054] In the laser engraving detection device provided in this embodiment, after the laser engraving machine 2 performs laser engraving on the electronic cigarette in the transport carrier 100, the transmission device 1 transports the transport carrier 100 to a position close to the CCD module 301, and the shifting manipulator 304 grabs the electronic cigarette in the transport carrier 100 and transfers it to the CCD module 301 for visual inspection:

[0055] If the inspection is qualified (for example, the laser engraved images and texts are complete and clear without any missing parts), the electronic cigarette is put back into the transport carrier 100, and then the next electronic cigarette is picked up for visual inspection;

[0056] If the inspection fails (for example, there is no laser engraved image or text, or the laser engraved image or text is unclear or missing), the electronic cigarette is placed in the NG recovery storage rack 302, and then an electronic cigarette is grabbed from the replenishment supply rack 303 and placed in the transport carrier 100; the significance of the replenishment operation is to ensure that the transport carrier 100 sent to the downstream is in a fully loaded state, so as to facilitate the standardized mechanical operation of the downstream equipment and avoid the electronic cigarettes sent by the transport carrier 100 actually affecting the automated production of the downstream equipment.

[0057] Therefore, the laser engraving detection equipment provided by the utility model can automatically inspect the electronic cigarette after laser engraving, thereby reducing labor costs and improving production efficiency.

[0058] In this embodiment, the transmission device 1 includes two conveyor belts 101 spaced apart from each other and a lifting mechanism located between the two conveyor belts 101 .

[0059] After the lifting mechanism lifts the transport carrier 100 upward, the shift robot 304 performs material picking and placing operations from the transport carrier 100, avoiding the conveyor belt 101 from being damaged by downward pressure during the picking and placing process, and also ensuring good support for the transport carrier 100.

[0060] See also Figure 3 Optionally, the CCD module 301 includes a workbench 3011 , a plurality of CCD cameras 3012 installed on the workbench 3011 , and a fill light 3013 located above each of the CCD cameras 3012 .

[0061] Optionally, the workbench 3011 includes a door-shaped bracket 3011a and a table top pad 3011c. The edge of the door-shaped bracket 3011a is provided with a column guide groove 3011b, and the table top pad 3011c is installed in the middle of the door-shaped bracket 3011a. Furthermore, the door-shaped bracket 3011a and the table top pad 3011c are fastened and connected by fastening bolts.

[0062] A vertical column 3016 is disposed on the top surface of the workbench 3011, and a lamp box mounting seat 3014 is disposed on the vertical column 3016. A lamp box rotating shaft 3015 is rotatably connected to the lamp box mounting seat 3014; wherein the fill light 3013 is mounted on the lamp box rotating shaft 3015. Optionally, the vertical column 3016 is fixedly mounted in the column guide groove 3011b in an adjustable manner.

[0063] By moving the vertical column 3016 forward and backward along the column guide groove 3011b, the position of the fill light 3013 can be adjusted forward and backward, and by rotating the light box shaft 3015, the light output angle of the fill light 3013 can be adjusted, thereby adjusting the fill light effect.

[0064] In this embodiment, the top surface of the table pad 3011c is also provided with a plurality of camera guide grooves 3011d which are arranged one by one corresponding to each CCD camera 3012 and are parallel to each column guide groove 3011b; each CCD camera 3012 is fixedly installed in the corresponding camera guide groove 3011d in an adjustable manner. By moving the CCD camera 3012 forward and backward along the camera guide groove 3011d, the position of the CCD camera 3012 can be adjusted forward and backward for manual focusing.

[0065] When it is necessary to replace a CCD camera 3012 of a different specification and size, it is only necessary to replace the table pad 3011c with the matching camera guide groove 3011d, and the door-type bracket 3011a can be reused.

[0066] Optionally, the table pad 3011c is provided with a plurality of pad magnetic parts, and the bottom of the CCD camera 3012 is provided with a camera magnetic part for magnetically positioning with each of the pad magnetic parts. For example, both the pad magnetic part and the camera magnetic part are magnets, or one of them is a magnet and the other is an iron block.

[0067] After sliding and adjusting the position of the CCD camera 3012 along the camera guide groove 3011d, the camera magnetic suction piece can be magnetically positioned with the pad magnetic suction piece at the corresponding position through the magnetic force, which is simple, convenient and efficient in positioning.

[0068] Optionally, it further includes a loading and unloading linear drive mechanism 305 that drives the NG recovery storage rack 302 and the replenishing feeding rack 303 to move closer to or farther from the shifting manipulator 304. When all the electronic cigarettes in the replenishing feeding rack 303 are taken out, the replenishing linear drive mechanism drives the replenishing feeding rack 303 to move outward so that new electronic cigarettes can be added manually or by a manipulator.

[0069] In summary, the laser engraving detection device provided in this embodiment has the following advantages:

[0070] ① After the laser engraving machine 2 performs laser engraving on the electronic cigarette in the transport carrier 100, the shifting robot 304 grabs the electronic cigarette in the transport carrier 100 and transfers it to the CCD module 301 for visual inspection, which can sort out defective products and replenish qualified products into the transport carrier 100 to avoid affecting the mechanized operation of the downstream process, thereby reducing labor costs and improving production efficiency;

[0071] ② The front and rear position and lighting angle of the fill light 3013 are adjustable, and the front and rear position of the CCD camera 3012 are adjustable, which is conducive to adapting to various detection working conditions;
