Description

Technical Field

[0001] This invention relates to the field of bottle cap detection device technology, and more particularly to a bottle cap QR code double-sided inspection and conveying device. Background Technology

[0002] QR codes have become the core information carrier for product traceability. Typically, QR codes are printed on both the inside and outside of the bottle cap. Accurate detection of the QR codes on the inside and outside of the bottle cap is a key step in ensuring the integrity and effectiveness of product traceability information.

[0003] Currently, most bottle cap inspection devices use a method of single-sided inspection followed by flipping the bottle cap for re-inspection. This not only requires the addition of a flipping mechanism, resulting in a complex overall structure and a high failure rate, but also presents a cumbersome inspection process. This makes it difficult to adapt to the high-efficiency inspection needs of large-scale production and fails to meet the actual requirements of high-precision inspection.

[0004] Therefore, there is an urgent need for a bottle cap QR code double-sided inspection and conveying device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a double-sided inspection and conveying device for bottle cap QR codes, which can simultaneously read and inspect the inner and outer QR codes on the bottle cap, thereby shortening the inspection time and improving production efficiency.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A bottle cap QR code double-sided inspection and conveying device includes a base, an inspection mechanism, and a feeding conveying mechanism and a carrying conveying mechanism arranged sequentially on the base along the X-axis. The feeding conveying mechanism is configured to convey the bottle cap to the carrying conveying mechanism along the X-axis. The base has a cutout at the carrying conveying mechanism.

[0008] The conveying mechanism includes a first drive assembly and two first conveyor belts. The two first conveyor belts extend along the X-axis and are symmetrically arranged at intervals along the Y-axis on both sides of the cutout. The two sides of the bottle cap can respectively overlap the two first conveyor belts. The first drive assembly is configured to drive the two first conveyor belts to move synchronously, thereby conveying the bottle cap along the X-axis.

[0009] The detection mechanism includes two cameras, which are suspended at intervals along the Z-axis on the upper and lower sides of the cutout and correspond to each other. They are configured to simultaneously detect the inner and outer QR codes of the bottle cap passing through the cutout. The X-axis, Y-axis and Z-axis are perpendicular to each other.

[0010] As an optional solution for a bottle cap QR code double-sided inspection and conveying device, the base is provided with multiple first air distribution holes evenly distributed on both sides of the hollow opening, and multiple second air distribution holes are evenly distributed on the two first conveyor belts; the bottle cap QR code double-sided inspection and conveying device also includes an adsorption component, which can output negative pressure gas. The negative pressure gas acts on the bottle cap overlapping the two first conveyor belts through the first air distribution holes and the second air distribution holes, so that the bottle cap is adsorbed on the two first conveyor belts to fix the bottle cap's posture.

[0011] As an optional solution for a bottle cap QR code double-sided inspection and conveying device, the adsorption assembly includes a control valve and two gas distribution blocks capable of conveying negative pressure gas. The two gas distribution blocks are respectively installed below the hollow opening on both sides of the base and are connected to the first gas distribution hole on the corresponding side. The control valve is configured to adjust the negative pressure gas pressure output by a single gas distribution block or both gas distribution blocks.

[0012] As an optional solution for a bottle cap QR code double-sided inspection conveying device, the bottle cap QR code double-sided inspection conveying device also includes a guide component. The guide component is disposed between the feeding conveying mechanism and the carrying conveying mechanism and is configured to guide the bottle cap to fine-tune its posture so that the bottle cap is conveyed along the X-axis direction to its two sides and respectively overlap the two first conveyor belts.

[0013] As an optional solution for a bottle cap QR code double-sided inspection conveying device, the guide assembly includes two positioning wheels, both of which extend along the Z-axis and are rotatably connected to the base, and are spaced apart along the Y-axis. The distance between the two positioning wheels is adapted to the width of a bottle cap, so as to limit only one bottle cap to passing through the interval area between the two positioning wheels at a time and being conveyed to the two first conveyor belts.

[0014] As an optional solution for a bottle cap QR code double-sided inspection conveying device, the feeding and conveying mechanism includes a second drive assembly and a second conveyor belt. The second conveyor belt can hold the bottle cap. The second drive assembly is configured to drive the second conveyor belt to move, thereby conveying the bottle cap on it along the X-axis direction.

[0015] As an optional solution for a bottle cap QR code double-sided inspection and conveying device, the inspection mechanism also includes a light source positioned corresponding to the cutout, which can provide uniform illumination to the two cameras to make the inner and outer QR codes of the bottle cap clear images.

[0016] As an optional solution for a bottle cap QR code double-sided inspection and conveying device, the first drive assembly includes:

[0017] The drive motor, the first gear, the second gear, and the transmission shaft are connected to the first gear. The transmission shaft passes through the second gear and is fixedly connected to the second gear. The first gear and the second gear mesh with each other.

[0018] Two first pulleys and two second pulleys, the two first pulleys are respectively fixed at both ends of the drive shaft, the two second pulleys are respectively located on the same side of their corresponding first pulleys, and the two first conveyor belts are respectively sleeved on the corresponding first pulleys and second pulleys and tensioned;

[0019] The drive motor can drive the first gear to rotate, which in turn drives the second gear meshing with it to rotate synchronously, thereby driving the transmission shaft and the first pulleys at both ends to rotate, which in turn drives the two first conveyor belts and the two second pulleys to move, so as to transport the bottle caps attached to the two first conveyor belts along the X-axis direction.

[0020] As an optional solution for a bottle cap QR code double-sided inspection conveying device, the bottle cap QR code double-sided inspection conveying device also includes two baffles. The two baffles extend along the X-axis and Z-axis directions and are spaced apart along the Y-axis direction. They are respectively set on both sides of the base and cover the conveying paths of the feeding conveying mechanism and the carrying conveying mechanism, thus preventing the bottle cap from detaching from both sides of the base during the conveying process.

[0021] As an optional solution for a bottle cap QR code double-sided inspection and conveying device, the base is made of metal.

[0022] The beneficial effects of this invention are:

[0023] This invention provides a bottle cap QR code double-sided inspection and conveying device. When using this device, the feeding conveyor transports the bottle cap along the X-axis to the carrying conveyor, so that both sides of the bottle cap overlap on two first conveyor belts of the carrying conveyor. A first driving component drives the two first conveyor belts to move synchronously, moving the bottle cap along the X-axis and passing through a cutout on the base. When the bottle cap is at the cutout, two cameras suspended above and below the cutout, corresponding to each other, simultaneously detect the inner and outer QR codes on the bottle cap, achieving double-sided QR code inspection. This bottle cap QR code double-sided inspection and conveying device stably carries and transports the bottle cap through symmetrically arranged first conveyor belts, and the two cameras suspended above and below the cutout simultaneously detect the QR codes. Double-sided inspection can be completed without flipping the bottle cap, simplifying the inspection process, improving inspection efficiency and accuracy, and ensuring that the QR code information of each bottle cap can be reliably identified.

[0036] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] like Figures 1-2 As shown, this embodiment provides a bottle cap QR code double-sided inspection and conveying device. The device includes a base 1, an inspection mechanism 2, and a feeding conveying mechanism 3 and a carrying conveying mechanism 4 sequentially arranged on the base 1 along the X-axis. The feeding conveying mechanism 3 transports the bottle cap 100 to the carrying conveying mechanism 4 along the X-axis. The base 1 has a cutout 11 at the carrying conveying mechanism 4. The carrying conveying mechanism 4 includes a first driving assembly and two first conveyor belts 41, both extending along the X-axis and along the Y-axis. The two sides of the cutout 11 are symmetrically arranged at intervals. The two sides of the bottle cap 100 can be respectively attached to the two first conveyor belts 41. The first driving component is used to drive the two first conveyor belts 41 to move synchronously and drive the bottle cap 100 to be transported along the X-axis direction. The detection mechanism 2 includes two cameras 21, which are suspended at intervals on the upper and lower sides of the cutout 11 along the Z-axis direction and correspond to each other. They are used to simultaneously detect the inner and outer QR codes of the bottle cap 100 passing through the cutout 11. The X-axis direction, Y-axis direction and Z-axis direction are perpendicular to each other.

[0038] When using the bottle cap QR code double-sided inspection conveying device, the feeding conveying mechanism 3 conveys the bottle cap 100 along the X-axis to the carrying conveying mechanism 4, so that the two sides of the bottle cap 100 overlap the two first conveyor belts 41 of the carrying conveying mechanism 4 respectively. The first driving component drives the two first conveyor belts 41 to move synchronously, driving the bottle cap 100 to be conveyed along the X-axis and through the cutout 11 of the base 1. When the bottle cap 100 is at the cutout 11, two cameras 21 suspended on the upper and lower sides of the cutout 11 and corresponding to each other simultaneously detect the inner and outer QR codes of the bottle cap 100, realizing double-sided inspection of the QR codes. This bottle cap QR code double-sided inspection conveying device stably carries and conveys the bottle cap 100 through symmetrically arranged first conveyor belts 41, and the two cameras 21 suspended above and below the cutout 11 detect synchronously. Double-sided inspection can be completed without flipping the bottle cap 100, simplifying the inspection process, improving inspection efficiency and accuracy, and ensuring that the QR code information of each bottle cap 100 can be reliably identified.

[0039] like Figure 1As shown, the base 1 has multiple first air distribution holes evenly distributed along both sides of the hollow opening 11, and the two first conveyor belts 41 have multiple second air distribution holes 411 evenly distributed. The bottle cap QR code double-sided inspection conveying device also includes an adsorption component, which can output negative pressure gas. The negative pressure gas passes through the first and second air distribution holes 411 and acts on the bottle cap 100 overlapping the two first conveyor belts 41, causing the bottle cap 100 to be adsorbed onto the two first conveyor belts 41 to fix the bottle cap 100's posture. The negative pressure gas output by the adsorption component firmly adsorbs and fixes the bottle cap 100 overlapping the two first conveyor belts 41 through the first and second air distribution holes 411, ensuring the stability of the bottle cap 100's posture, effectively preventing the bottle cap 100 from shifting or shaking during conveying and inspection, ensuring the accurate recognition of the QR code by the upper and lower cameras 21, and further improving the accuracy and reliability of double-sided inspection.

[0040] In this embodiment, the adsorption assembly includes a control valve and two gas distribution blocks capable of conveying negative pressure gas. The two gas distribution blocks are respectively installed below the hollow opening 11 on both sides of the base 1 and are connected to the first gas distribution hole on the corresponding side. The control valve is used to adjust the negative pressure gas output of a single gas distribution block or both gas distribution blocks, which can adapt to the adsorption requirements of bottle caps 100 of different specifications. The adsorption assembly can flexibly adjust the negative pressure output pressure of a single or two gas distribution blocks through the control valve, which can accurately adapt to the adsorption requirements of bottle caps 100 of different specifications, avoid deformation of bottle caps 100 due to excessive negative pressure or deviation of bottle cap 100 due to insufficient negative pressure, and ensure that bottle caps 100 of various specifications can maintain a stable posture during transportation and inspection, thereby improving the applicability of the bottle cap QR code double-sided inspection and transportation device.

[0041] like Figure 1 As shown, the bottle cap QR code double-sided inspection conveying device also includes a guide component 5. The guide component 5 is located between the feeding conveying mechanism 3 and the carrying conveying mechanism 4, and is used to guide the bottle cap 100 to fine-tune its posture, so that the bottle cap 100 is conveyed along the X-axis direction to its two sides overlap with the two first conveyor belts 41 respectively. The guide component 5 can precisely fine-tune the posture of the bottle cap 100 during the transfer from the feeding conveying mechanism 3 to the carrying conveying mechanism 4, ensuring that the two sides of the bottle cap 100 can stably overlap with the two first conveyor belts 41, effectively avoiding conveying jams or subsequent camera 21 misalignment caused by the posture deviation of the bottle cap 100, and ensuring the continuity of the double-sided inspection process and the stability of the inspection results.

[0042] like Figure 1As shown, the guide assembly 5 includes two positioning wheels 51. Both positioning wheels 51 extend along the Z-axis and are rotatably connected to the base 1, and are spaced apart along the Y-axis. The spacing between the two positioning wheels 51 is adapted to the width of a bottle cap 100, so as to limit only one bottle cap 100 to pass through the interval area between the two positioning wheels 51 at a time and be conveyed onto the two first conveyor belts 41. The two positioning wheels 51 of the guide assembly 5 are arranged at a spacing adapted to the bottle caps 100, which can not only allow one bottle cap 100 to pass through sequentially, but also prevent multiple bottle caps 100 from being conveyed side by side onto the first conveyor belt 41, causing jamming or offset problems. At the same time, the rotation of the two positioning wheels 51 can accurately guide and calibrate the posture of the bottle caps 100, ensuring that the two sides of the bottle caps 100 are stably attached to the two first conveyor belts 41, laying the foundation for accurate alignment in subsequent inspection processes.

[0043] like Figures 1-2 As shown, the feeding and conveying mechanism 3 includes a second drive assembly and a second conveyor belt 31. The second conveyor belt 31 can hold bottle caps 100. The second drive assembly drives the second conveyor belt 31 to move, causing the bottle caps 100 on it to be conveyed along the X-axis. The feeding and conveying mechanism 3 drives the second conveyor belt 31 through the second drive assembly to stably convey the bottle caps 100 to the guide assembly 5, providing a stable material supply. After the bottle caps 100 are adjusted in posture by the guide assembly 5, they are conveyed to the two first conveyor belts 41, realizing continuous feeding of bottle caps 100 and improving the overall operation efficiency of double-sided inspection.

[0044] In this embodiment, the second drive component includes a servo motor and two pulleys. The second conveyor belt 31 is fitted onto the two pulleys and tensioned. The output end of the servo motor is connected to either pulley for transmission. The servo motor can drive the pulley to rotate, thereby driving the second conveyor belt 31 and the other pulley to move, and thus driving the bottle cap 100 on the second conveyor belt 31 to be conveyed along the X-axis. The running speed and start / stop timing of the second conveyor belt 31 can be precisely controlled. The transmission response is fast and the running stability is high, thereby precisely controlling the conveying speed of the bottle cap 100 along the X-axis.

[0045] like Figures 1-2 As shown, the detection mechanism 2 also includes a light source 22, which is positioned corresponding to the cutout 11. This light source provides uniform illumination to the two cameras 21, ensuring clear imaging of the inner and outer QR codes on the bottle cap 100. The uniform illumination provided by the light source 22, corresponding to the cutout 11, effectively optimizes the imaging environment of the inner and outer QR codes on the bottle cap 100, eliminating interference factors such as reflections and shadows. This ensures that the QR code images captured by the two cameras 21 are clear and complete, significantly improving QR code recognition accuracy and guaranteeing the reliability of the two-way inspection results.

[0046] In this embodiment, there are two light sources 22, which are configured one-to-one with two cameras 21 to provide uniform illumination for the two cameras 21, significantly improving the accuracy of QR code recognition and ensuring the reliability of the two-way inspection results. In other embodiments, the number of light sources 22 may be three, four, five, etc., and no specific limitation is made here.

[0047] In this embodiment, the first driving assembly includes a drive motor, a first gear, a second gear, a transmission shaft, two first pulleys, and two second pulleys. The output end of the drive motor is connected to the first gear, and the transmission shaft passes through and is fixedly connected to the second gear. The first gear and the second gear mesh with each other. The two first pulleys are respectively fixed at both ends of the transmission shaft, and the two second pulleys are respectively located on the same side of their corresponding first pulleys. The two first conveyor belts 41 are respectively sleeved on the corresponding first pulleys and second pulleys and tensioned. The drive motor can drive the first gear to rotate, thereby driving the second gear meshing with it to rotate synchronously, and then driving the transmission shaft and the first pulleys at both ends to rotate, driving the two first conveyor belts 41 and the two second pulleys to move, so as to drive the bottle caps 100 attached to the two first conveyor belts 41 to be conveyed along the X-axis direction. The drive motor is used in conjunction with gear meshing transmission to drive the transmission shaft and the first pulleys at both ends to rotate synchronously, driving the two first conveyor belts 41 to transport synchronously, ensuring that the bottle caps 100 overlapping the two first conveyor belts 41 are transported smoothly and accurately along the X-axis. The transmission structure is compact and the power transmission is efficient, which greatly improves the stability of the bottle caps 100 transport.

[0048] In this embodiment, the bottle cap QR code double-sided inspection conveying device also includes two baffles. Both baffles extend along the X-axis and Z-axis directions and are spaced apart along the Y-axis. They are respectively positioned on both sides of the base 1 and cover the conveying paths of the feeding conveying mechanism 3 and the carrying conveying mechanism 4, preventing the bottle cap 100 from detaching from both sides of the base 1 during conveying. The two baffles cover both sides of the feeding conveying mechanism 3 and the carrying conveying mechanism 4 along the entire conveying path, effectively limiting the bottle cap 100 from shifting to either side or detaching during conveying. This ensures the bottle cap 100 stably switches between the feeding area, the posture adjustment area, and the inspection area, further improving the continuity and stability of the bottle cap QR code double-sided inspection conveying device.

[0049] In this embodiment, the base 1 is made of metal. Metal has excellent structural strength and rigidity, which can stably support the feeding conveyor mechanism 3 and the supporting conveyor mechanism 4, effectively avoiding deformation problems during long-term operation; at the same time, metal is wear-resistant and corrosion-resistant, extending the overall service life of the bottle cap QR code double-sided inspection conveyor device and adapting to the high-intensity operation requirements of large-scale production.
