[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example: Figure 1-5 As shown, this utility model provides a box label detection device, which includes a frame 1, a photoelectric sensor 2, a scanning camera 3, a PLC controller 4, and a signal light 5. The photoelectric sensor 2, the scanning camera 3, and the signal light 5 are connected to the PLC controller 4. When the outer box of the finished product moves to the position of the photoelectric sensor 2, it triggers the switch of the photoelectric sensor 2 to output a corresponding signal to the PLC controller 4. The PLC controller 4, based on the current state, triggers the scanning camera 3 to take a picture of the outer box in position and read the QR code on the outer box. The scanning camera 3 analyzes the data of the read QR code. If the QR code is successfully decoded, it outputs an OK signal and then transmits it to the PLC controller 4. The PLC controller 4 performs different signal output processing based on the received signal, turning on the signal light 5 (green light) and storing and recording the data. If the QR code is not decoded, the scanning camera 3 outputs an NG signal and then transmits it to the PLC controller 4. The PLC controller 4 performs different signal output processing based on the received signal, turning on the signal light 5 (red light) and storing and recording the data, thus completing the entire data acquisition, judgment, and output processing.

[0030] The photoelectric sensor 2 and the scanning camera 3 are mounted on one side of the equipment frame 1. The bottom of the equipment frame 1 is fixedly connected to the base 11, and the base 11 has a number of evenly distributed mounting holes 12. By setting the base 11 and the mounting holes 12, it is convenient for the operators to assemble the equipment frame 1 on the finished product outer box assembly line, so that the photoelectric sensor 2 and the scanning camera 3 face the finished product outer box. The equipment frame 1 is provided with a mounting component 6. By setting the mounting component 6, it is convenient for the operators to install and remove the photoelectric sensor 2 and the scanning camera 3. The equipment frame 1 is provided with an adjustment component 8. By setting the adjustment component 8, it is convenient for the operators to adjust the height of the installed photoelectric sensor 2 and the scanning camera 3.

[0031] Mounting assembly 6 includes a mounting sleeve 61. Two mounting slots 611 are provided on one side of the mounting sleeve 61, allowing the signal cables of the photoelectric sensor 2 and scanning camera 3 to extend out of the mounting sleeve 61 and connect to the PLC controller 4. A partition plate 62 is fixedly installed in the middle of the mounting sleeve 61, dividing the inner wall of the mounting sleeve 61 into two cavities, allowing the photoelectric sensor 2 and scanning camera 3 to be placed in the mounting sleeve 61. First elastic pads 63 are fixedly installed on both the upper and lower surfaces of the partition plate 62, protecting the photoelectric sensor 2 and scanning camera 3. The photoelectric sensor 2 and scanning camera 3 are detachably mounted on the inner wall of the mounting sleeve 61. Two clamping plates 64 are provided inside the mounting sleeve 61, with a second elastic pad 65 fixedly installed on one side of each clamping plate 64. By using the clamping plates 64 and the second elastic pads 65, when the clamping plates 64 face... When the photoelectric sensor 2 or the scanning camera 3 moves, the photoelectric sensor 2 or the scanning camera 3 can be pressed into the mounting sleeve 61 by the second elastic pad 65. The inner wall of the mounting sleeve 61 is provided with four evenly distributed guide grooves 66. Two guide blocks 67 are fixedly provided on each of the two clamping plates 64. The guide blocks 67 are slidably disposed in the guide grooves 66. By setting the guide grooves 66 and the guide blocks 67, the guide blocks 67 can slide vertically along the inner wall of the guide grooves 66, thereby guiding the clamping plates 64 vertically and keeping the clamping plates 64 moving vertically. Threaded rods 68 are threadedly mounted on both the upper and lower surfaces of the mounting sleeve 61. One end of one of the threaded rods 68 is rotatably connected to one side of a clamping plate 64. The other end of both threaded rods 68 is fixedly provided with a rotating handle 69. By manually rotating the rotating handle 69, the rotating handle 69 can rotate the threaded rod 68, and the threaded rod 68 can drive the clamping plate 64 to move vertically within the mounting sleeve 61.

[0032] The mounting sleeve 61 has two push plates 7 inside. Four Z-shaped elastic elements 71 are fixedly installed on the side wall of the mounting sleeve 61. One side of two adjacent Z-shaped elastic elements 71 and one side of a push plate 7 are fixedly connected. By setting the Z-shaped elastic elements 71 and the push plates 7, when the photoelectric sensor 2 or the scanning camera 3 is pushed into the interior of the mounting sleeve 61, the photoelectric sensor 2 or the scanning camera 3 can move the push plate 7. The push plate 7 causes the Z-shaped elastic elements 71 to contract. When the clamping plate 64 releases the clamping force of the photoelectric sensor 2 or the scanning camera 3, the Z-shaped elastic elements 71 reset. The push plate 7 pushes the photoelectric sensor 2 or the scanning camera 3 to move horizontally away from the mounting sleeve 61, so that the operator can easily remove the photoelectric sensor 2 or the scanning camera 3 from the mounting sleeve 61.

[0033] The adjustment assembly 8 includes a slider 81. A slide groove 82 is provided on the equipment frame 1. The slider 81 is slidably disposed at one end of the slide groove 82. Two connecting plates 83 are fixedly disposed on one side of the slider 81. One end of each connecting plate 83 is fixedly connected to one side of the mounting sleeve 61. By driving the slider 81 to slide vertically within the slide groove 82, the slider 81 can vertically raise and lower the mounting sleeve 61 via the connecting plates 83, thereby synchronously raising and lowering the photoelectric sensor 2 and the scanning camera 3, achieving height adjustment of the installed photoelectric sensor 2 and scanning camera 3. A lead screw 84 is rotatably mounted on the equipment frame 1, passing through the slide groove 82 and connecting with the slide... Block 81 is threaded and rotated. It drives the lead screw 84 to rotate, and the lead screw 84 can drive the slider 81 to slide vertically in the slide groove 82. A motor 85 is fixedly installed at the top of the equipment frame 1. An L-shaped support frame 86 is fixedly installed at the fixed end of the motor 85. One end of the L-shaped support frame 86 is fixedly connected to the top of the equipment frame 1. A worm 87 is fixedly installed at the drive output end of the motor 85. A worm wheel 88 is fixedly installed at one end of the lead screw 84. The worm 87 and the worm wheel 88 are meshed and connected. When the motor 85 is turned on, the drive shaft of the motor 85 can rotate the worm wheel 88 through the worm 87. The worm wheel 88 can then rotate the lead screw 84.

[0034] Working principle: When it is necessary to install the photoelectric sensor 2 and the scanning camera 3, the operator first pushes the photoelectric sensor 2 and the scanning camera 3 into the mounting sleeve 61 respectively. The photoelectric sensor 2 and the scanning camera 3 enter the mounting sleeve 61 and push the two push plates 7 to move. The two push plates 7 cause the Z-shaped elastic element 71 to contract.

[0035] Subsequently, the operator rotates the two rotating handles 69, which causes the two threaded rods 68 to rotate. The two threaded rods 68 cause the two clamping plates 64 to move toward the photoelectric sensor 2 and the scanning camera 3. The two clamping plates 64 press the photoelectric sensor 2 and the scanning camera 3 into the mounting sleeve 61 through the corresponding second elastic pads 65, thus facilitating the quick installation of the photoelectric sensor 2 and the scanning camera 3. The reverse operation can be used to disassemble the photoelectric sensor 2 and the scanning camera 3, thereby effectively improving the convenience of installing and disassembling the photoelectric sensor 2 and the scanning camera 3.

[0036] When the height of the installed photoelectric sensor 2 and scanning camera 3 needs to be adjusted, the operator turns on the motor 85. The drive shaft of the motor 85 causes the worm gear 87 to rotate, which in turn drives the worm wheel 88 to rotate. The worm wheel 88 then causes the lead screw 84 to rotate, which in turn drives the slider 81 to slide vertically within the slide groove 82. The slider 81, through two connecting plates 83 and the mounting sleeve 61, causes the photoelectric sensor 2 and scanning camera 3 to rise and fall vertically, so that the height of the photoelectric sensor 2 and scanning camera 3 is adapted to the height of the box label on the outer casing of the finished product (for the scanning camera 3 to scan the box label). This facilitates the height adjustment of the installed photoelectric sensor 2 and scanning camera 3, thereby effectively improving the convenience of height adjustment.

[0037] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
