[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] The following is combined with Figure 1-5 This application is described in further detail.
[0024] A lens laser engraving effect detection device comprises a body 3 of a laser engraving machine and a manipulator 1, the manipulator 1 is arranged on the body 3, a detection device 2 is arranged on the body 3, the detection device 2 comprises a support column 5, a sensor 8 and a fixing plate 9, the support column 5 is fixedly arranged on the body 3, the fixing plate 9 is fixedly arranged on the body 3, a mounting hole 14 is opened on the fixing plate 9, a light-transmitting plate 13 is fixedly arranged in the mounting hole 14, a placement groove is formed between the light-transmitting plate 13 and the mounting hole 14, and the lens with detection is placed in the placement groove.
[0025] A first cylinder 7 is fixedly provided on the support column 5, a fixed block 6 is fixedly provided on the telescopic shaft of the first cylinder 7, the fixed block 6 is pressed against the fixed plate 9, a fixing hole 15 is opened in the fixed block 6, a sensor 8 is fixedly provided in the fixing hole 15, the sensor 8 is below the mounting hole 14, and the sensing head of the sensor 8 faces the mounting hole 14.
[0026] A moving device is provided on the support column 5, and the moving device includes a second cylinder 17 and a third cylinder 11. The second cylinder 17 is fixedly arranged on the support column 5, and the third cylinder 11 is fixedly connected to the telescopic axis of the second cylinder 17. The second cylinder 17 is horizontally arranged on the support column 5, and the third cylinder 11 and the second cylinder 17 are perpendicular to each other.
[0027] The telescopic shaft of the third cylinder 11 is fixedly connected with a positioning block 10, which is pressed against the fixing plate 9, and the fixing plate 9 is between the positioning block 10 and the fixing block 6. A mounting groove 16 is provided on one side of the positioning block 10 close to the fixing plate 9, and a lighting lamp 12 is fixedly arranged in the mounting groove 16, and the lighting lamp 12 is directly opposite to the mounting hole 14, and the light-transmitting plate 13 is between the lighting lamp 12 and the sensor 8.
[0028] The area of the positioning block 10 is larger than the area of the mounting hole 14, and the area of the fixing block 6 is larger than the area of the mounting hole 14. When the robot 1 transports the lens to the light-transmitting plate 13, the positioning block 10 and the fixing block 6 are respectively pressed against the fixing plate 9, and the lighting lamp 12 emits light to illuminate the lens. Under the action of the positioning block 10 and the fixing block 6, the lens is detected in a closed environment and the light will not be radiated out.
[0029] An alarm indicator light 4 is fixedly provided on the support column 5, and the alarm indicator light 4 is electrically connected to the sensor 8. When the sensor 8 senses that the lens laser engraving is unqualified, the alarm indicator light 4 emits a red light warning to warn the staff to deal with the unqualified lens.
[0030] The fixing plate 9 is made of a light-proof material so that the light of the illuminating lamp 12 does not leak to the outside, thus ensuring the detection effect of the lens. A tightening layer 18 is fixedly provided on one side of the positioning block 10 close to the fixing plate 9. When the lens is placed in the light-transmitting plate 13, the positioning block 10 moves down, the tightening block presses against the fixing plate 9, and the tightening layer 18 presses against the lens, so that the lens is placed more closely on the light-transmitting plate 13 for easy detection.
[0031] The implementation principle of this embodiment is: when the laser engraving of the lens is completed, the robot 1 transports the lens to the top of the fixed plate 9, the robot 1 places the lens on the light-transmitting plate 13, and starts the second cylinder 17. The third cylinder 11 and the positioning block 10 move to the top of the lens under the use of the second cylinder 17, and the third cylinder 11 is started. The positioning block 10 approaches the lens and the positioning block 10 is pressed against the fixed plate 9. The lens is fixed between the light-transmitting plate 13 and the positioning block 10, and the first cylinder 7 is started. The fixed block 6 approaches the fixed plate 9 and the fixed block 6 is pressed against the fixed plate 9. The lighting lamp 12 is turned on, and the lighting lamp 12 emits light to illuminate the lens. When the light emitted by the lighting lamp 12 can pass through the lens through the light-transmitting plate 13 to act on the sensor 8, the sensor 8 senses the light, which means that the laser engraving effect of the lens is qualified. Otherwise, the laser engraving effect of the lens is unqualified, thereby achieving the effect of detecting the laser engraving effect of the lens.
