Description

Technical Field

[0001] The utility model relates to the field of bottle cap production, in particular to a device for detecting two-dimensional codes of bottle caps. Background Art

[0002] When bottle caps are produced, it is often necessary to print QR codes on the formed bottle caps. The functions of QR codes are usually multiple, such as: the QR code can contain a unique product serial number, consumers can verify the authenticity of the product by scanning, and prevent the circulation of counterfeit and inferior products; the QR code can be linked to the brand website or marketing event page, providing coupons, participation in lotteries, points redemption and other promotional activities to enhance interaction with consumers; the QR code can contain a unique product serial number, consumers can verify the authenticity of the product by scanning, and prevent the circulation of counterfeit and inferior products. It can be seen that the role of QR codes is relatively large.

[0003] However, when printing the QR code, the printing device may vibrate due to mechanical wear, unbalanced load, external interference, or the inherent frequency problem of the device itself. The vibration will cause the printing head to have a slight deviation when moving, causing the QR code pattern printed on the bottle cap to shake, resulting in blurred lines of the QR code. In order to ensure that the QR code on the bottle cap can be correctly scanned and recognized, the bottle cap needs to rely on the detection device to identify and detect the QR code after the QR code is printed. However, the placement of the bottle cap will directly affect whether the QR code is aligned with the detection device. If the bottle cap is offset, the QR code cannot be located in the center of the field of view of the detection device, causing the pattern to exceed the capture range of the camera and thus cannot be fully read.

For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections, or mutual communication; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0031] Reference Figure 1-Figure 5 In some specific embodiments, a device for detecting a QR code on a bottle cap includes a base 1, a support frame 2 is provided on the top of the base 1, an identification camera 25 is provided on one side of the support frame 2, a placement seat 5 is rotatably connected to the top of the base 1, and the placement seat 5 is used to place the bottle cap 8. An adjustment motor 3 is provided inside the base 1, and the adjustment motor 3 drives the placement seat 5 to rotate. A mounting seat 13 is provided on the top of the base 1, and a distance sensor 14 is provided on one side of the mounting seat 13. The identification end of the distance sensor 14 faces the top of the bottle cap 8, and a positioning column 10 is provided on the top of the bottle cap 8 near the QR code 9. The distance sensor 14 is used to identify the proximity of the positioning column 10. A controller 4 is provided inside the base 1, and the controller 4 is connected to the distance sensor 14 and the adjustment motor 3 by signal.

[0032] Through the above technical solution, when the bottle cap 8 is placed on the placement seat 5, the adjustment motor 3 is started, the adjustment motor 3 drives the placement seat 5 to rotate, and the distance sensor 14 starts to detect the position of the positioning column 10 of the bottle cap 8. When the distance sensor 14 detects that the positioning column 10 of the bottle cap 8 is approaching, the distance sensor 14 will send an approach signal to the controller 4. After receiving the approach signal, the controller 4 controls the adjustment motor 3 to turn off. Since the positioning column 10 is set close to the QR code 9, the recognition end of the distance sensor 14 is close to the detection end of the recognition camera 25, so that the QR code 9 of the bottle cap 8 is facing the recognition camera 25, and the placement position of the bottle cap 8 is calibrated, so that the QR code 9 of the bottle cap 8 is accurately placed in the field of view of the recognition camera 25, creating the best conditions for image capture by the recognition camera 25 and recognition of the QR code 9.

[0033] In addition, the distance sensor 14 generally adopts photoelectric, ultrasonic or other non-contact technologies, and can accurately measure the distance between the distance sensor 14 and the positioning post 10 .

[0034] Reference Figure 3-Figure 4 In some specific embodiments, clamping blocks 7 are provided on both sides of the placement seat 5 , and the clamping blocks 7 are elastic. The clamping blocks 7 on both sides of the placement seat 5 respectively contact the two sides of the inside of the bottle cap 8 .

[0035] Through the above technical solution, when the bottle cap 8 is placed on the placement seat 5, the elastic clamping block 7 can provide appropriate pressure, so that the clamping block 7 fixes the bottle cap 8 and prevents the bottle cap 8 from shifting during placement or rotation.

[0036] Reference Figure 3-Figure 4 In some specific embodiments, mounting grooves 6 are opened on both sides of the placement seat 5, the clamping block 7 matches the shape of the mounting groove 6, and the clamping block 7 is arranged inside the mounting groove 6 so that one end of the clamping block 7 protrudes outside the mounting groove 6.

[0037] Through the above technical solution, the shape of the clamping block 7 matches that of the mounting groove 6, ensuring that the clamping block 7 can be stably installed in the mounting groove 6 and will not become loose or shifted during the rotation of the placement seat 5.

[0038] Reference Figure 3-Figure 4 In some specific embodiments, an adjustment frame 11 is provided on the top of the base 1, an adjustment cavity 34 is opened inside the adjustment frame 11, guide sliders 16 are provided on both sides of the mounting seat 13, and guide grooves 12 are opened on both sides of the adjustment cavity 34. The guide sliders 16 on both sides of the mounting seat 13 slide with the guide grooves 12 on both sides of the interior of the adjustment cavity 34 respectively.

[0039] Through the above technical solution, when the batch of bottle caps 8 to be detected changes, the height of the bottle caps 8 will also change, so it is necessary to adjust the position of the mounting base 13. When the mounting base 13 is adjusted, the guide sliders 16 on both sides of the mounting base 13 can be pushed or pulled to move along the guide grooves 12. The height of the mounting base 13 can be accurately adjusted so that the distance sensor 14 and the positioning column 10 of the bottle cap 8 are at the same horizontal plane.

[0040] Reference Figure 4 In some specific embodiments, a fixing plate 17 is provided on one side of the adjustment frame 11, and a plurality of first fixing holes 18 are opened inside the fixing plate 17. A second fixing hole 20 is opened inside the mounting seat 13. A fixing pin 19 is passed through any of the first fixing holes 18, and the insertion end of the fixing pin 19 is plugged into the second fixing hole 20.

[0041] Through the above technical solution, when it is necessary to fix the position of the mounting base 13, the operator can pass the fixing pin 19 through the first fixing hole 18 of the fixing plate 17, so that the insertion end of the fixing pin 19 is inserted into the second fixing hole 20 of the mounting base 13, thereby locking the mounting base 13 so that the mounting base 13 will not move due to external force or vibration.

[0042] Reference Figure 1-Figure 5 In some specific embodiments, a movable cavity 33 is opened inside the support frame 2, and a lifting screw rod 21 is rotatably connected inside the movable cavity 33. A lifting nut 22 is sleeved on the outside of the lifting screw rod 21, and a lifting seat 23 is provided on one side of the lifting nut 22. An identification seat 24 is provided at the bottom of the lifting seat 23, and an identification camera 25 is installed at the bottom of the identification seat 24.

[0043] Through the above technical solution, when the position of the identification camera 25 needs to be adjusted, the lifting nut 22 can be rotated to move the lifting nut 22 up and down along the lifting screw 21, thereby driving the lifting seat 23 and the identification seat 24 to move up and down, thereby achieving precise height adjustment of the identification camera 25 and ensuring that the identification camera 25 can always be aligned with the QR code 9 on the bottle cap 8 at the optimal angle.

[0044] Reference Figure 1-Figure 5 In some specific embodiments, the top of the support frame 2 is rotatably connected to an adjusting dial 28 , and the adjusting dial 28 is coaxially driven with the lifting screw 21 .

[0045] Through the above technical solution, when the operator rotates the adjusting dial 28, the rotation of the lifting screw 21 will cause the lifting nut 22 to move up and down along the lifting screw 21 through the action of the thread. The design of the adjusting dial 28 simplifies the complexity of the mechanism, reduces the energy loss during the transmission process, and improves the transmission efficiency.

[0046] Reference Figure 5 In some specific embodiments, a plurality of first adjustment holes 29 are opened inside the adjustment dial 28, and a second adjustment hole 30 is opened on the top of the support frame 2. An adjustment pin 31 is passed through any first adjustment hole 29, and the adjustment pin 31 is plugged into the second adjustment hole 30.

[0047] Through the above technical solution, the adjustment pin 31 is used to pass through the first adjustment hole 29 of the adjustment dial 28 and be plugged into the second adjustment hole 30 of the support frame 2, so that the position of the adjustment dial 28 is fixed. When the position of the adjustment dial 28 is fixed, the rotation of the lifting screw rod 21 also stops, thereby fixing the adjusted height of the identification camera 25.

[0048] Reference Figure 5 In some specific embodiments, lifting grooves 27 are opened on both sides of the movable cavity 33, and lifting sliders 26 are provided on both sides of the lifting seat 23. The lifting sliders 26 on both sides of the lifting seat 23 slide with the lifting grooves 27 on both sides of the movable cavity 33 respectively.

[0049] Through the above technical solution, the cooperation between the lifting slider 26 and the lifting slot 27 makes the movement of the lifting seat 23 in the movable cavity 33 stable, preventing the lifting seat 23 from deviating from the path due to vibration or external interference.

[0050] Reference Figure 1-Figure 5 In some specific implementations, the controller 4 is a PLC controller 4 .
