[0002] The anti-counterfeiting printing detection device for packaging boxes relies on technologies such as visual sensors and optical sensing. It is a specialized detection device adapted to the production and distribution of packaging boxes. Its core function is to ensure the effectiveness and standardization of anti-counterfeiting printing, while screening out unqualified products and protecting the interests of brands and consumers.
[0003] The existing anti-counterfeiting printing detection device for packaging boxes consists of a base, a conveying mechanism, a mounting frame, and a vision sensor. The output mechanism conveys the packaging box to the bottom of the vision sensor, which then detects the printing on the packaging box. However, when the surface temperature of the vision sensor lens is lower than the dew point of the ambient air, the lens surface of the vision sensor will fog up, which will cause the image detected by the vision sensor to be blurry, resulting in low detection efficiency.
[0004] Therefore, we have made improvements to this and proposed an anti-counterfeiting printing detection device for packaging boxes. Summary of the Invention

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.
[0019] As described in the background art, when the surface temperature of the vision sensor lens is lower than the dew point of the ambient air, the lens surface of the vision sensor will fog up, which will blur the image detected by the vision sensor and result in low detection efficiency.
[0020] To address this technical problem, the present invention provides an anti-counterfeiting printing detection device for packaging boxes, which is applied to sensor detection.
[0021] For details, please refer to Figure 1 - Figure 10 As shown, the anti-counterfeiting printing detection device for packaging boxes specifically includes: a base 1, a conveying mechanism 101 disposed on the base 1, a mounting frame 102 disposed on the base 1, a sensor 103 disposed on the mounting frame 102, and a synchronous adjustment mechanism 2 disposed on the mounting frame 102. In the prior art, the sensor 103 is an existing vision sensor 103, and the conveying mechanism 101 is used to convey the packaging box to the working area of the sensor 103. The synchronous adjustment mechanism 2 includes a conveying chamber 201 mounted on the mounting frame 102, a vacuum pump 202 mounted on the mounting frame 102, a connecting pipe 203 mounted on the vacuum pump 202, a hollow seat 1 204 mounted on the mounting frame 102, a hollow seat 205 rotatably mounted on the hollow seat 1 204, a wedge-shaped part 206 mounted on the hollow seat 205, an air outlet 207 mounted on the wedge-shaped part 206, and a discharge pipe 208 fixedly passing through the conveying chamber 201 and the hollow seat 1 204.
[0022] The anti-counterfeiting printing detection device for packaging boxes provided by this invention addresses the problem in the prior art where fogging occurs on the lens surface of the vision sensor 103 when the surface temperature is lower than the dew point of the ambient air, resulting in blurred images and low detection efficiency. This application utilizes a synchronous adjustment mechanism 2 to heat the lens of the sensor 103 with hot air discharged from the synchronous adjustment mechanism 2, thereby raising the surface temperature of the sensor 103 lens above the dew point of the ambient air, reducing blurring during detection, and improving detection efficiency. By using the synchronous adjustment mechanism 2, air is blown onto the lens of sensor 103 from multiple angles, thus achieving multi-angle dust removal and reducing dust adhesion to the lens of sensor 103. This solves the problem of dust adhesion to the lens of sensor 103 affecting detection in the prior art. By using the synchronous adjustment mechanism 2, the fixed plate 214 rotates and protects the sensor 103, preventing the misaligned packaging box from contacting the sensor 103 and avoiding physical damage to the sensor 103. This solves the problem of physical collisions damaging the sensor 103 in the prior art.
[0023] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0024] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0026] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, an anti-counterfeiting printing detection device for packaging boxes has a connecting pipe 203 fixedly inserted through the conveying chamber 201, an exhaust pipe 208 set on the mounting frame 102, and an air outlet 207 adapted to the sensor 103. In use, the air pump 202 is started, drawing outside air into the connecting pipe 203, and then transferring the air to the delivery chamber 201 through the connecting pipe 203. Figure 7As shown, sensor 103 is located inside conveying chamber 201. Air enters discharge pipe 208 from conveying chamber 201, and then enters hollow seat 1 204 and hollow seat 2 205 from discharge pipe 208, finally exiting from air outlet 207. Sensor 103 generates heat during prolonged operation. The air flowing within conveying chamber 201 provides air cooling for sensor 103, thus reducing the risk of sensor 103 failure due to high temperatures and extending its service life. When the air in conveying chamber 201 comes into contact with sensor 103 and heats up... The air inside the hollow base 204 and the hollow base 205 is hot air. The hot air discharged through the air outlet 207 heats the lens of the sensor 103, making the surface temperature of the sensor 103 lens higher than the dew point of the ambient air. If the lens of the sensor 103 is fogged up, the hot air can accelerate the evaporation of water vapor from the lens of the sensor 103. This reduces the blurring of the sensor 103 during detection and improves the detection efficiency. The wedge-shaped part 206 causes the air outlet 207 to tilt and blow onto the lens of the sensor 103, thus preventing dust from sticking to the lens of the sensor 103. Furthermore, a motor 209 is provided on the mounting bracket 102, a drive shaft 210 is provided at the output end of the motor 209, a drive gear 211 is provided on the drive shaft 210, and a transmission gear 212 is provided on the hollow seat 205. The drive gear 211 and the transmission gear 212 are compatible. By starting the motor 209, the motor 209 drives the drive shaft 210 to rotate, the drive shaft 210 drives the drive gear 211 to rotate, the drive gear 211 drives the transmission gear 212 to rotate, and the transmission gear 212 drives the hollow base 205 to rotate synchronously. At this time, when the air outlet 207 blows air onto the lens of the sensor 103, the air outlet 207 and the hollow base 205 rotate synchronously. By rotating and blowing air onto the lens of the sensor 103, dust removal from multiple angles is achieved, reducing the situation of dust sticking to the lens. At the same time, by heating the lens from multiple angles, uneven heating of the lens is avoided. Furthermore, a protective cover 213 is provided on the mounting bracket 102, and a fixing plate 214 is provided on the hollow base 205; The drive gear 211 and transmission gear 212 are protected by the protective cover 213 to prevent the equipment from jamming. When the hollow seat 205 rotates, the fixing plate 214 on the hollow seat 205 rotates synchronously. When the packaging box conveyed by the conveying mechanism 101 is not aligned and comes into contact with the fixing plate 214, the rotating fixing plate 214 squeezes the unequal packaging box, causing the unequal packaging box to move to a position that does not interfere with the normal operation of the sensor 103. In this way, the unequal packaging box is avoided from coming into contact with the sensor 103, thus avoiding physical damage to the sensor 103. The hot air discharged by the synchronous adjustment mechanism 2 heats the lens of the sensor 103, making the surface temperature of the sensor 103 lens higher than the dew point of the ambient air. This reduces blurring during detection by the sensor 103 and improves detection efficiency. By blowing air onto the lens of the sensor 103 from multiple angles, dust removal is achieved from multiple angles, reducing the amount of dust adhering to the lens of the sensor 103. The rotation of the fixing plate 214 protects the sensor 103 and prevents contact between the improperly positioned packaging box and the sensor 103, thus avoiding physical damage to the sensor 103.
[0027] Example 2 further optimizes the anti-counterfeiting printing detection device for packaging boxes provided in Example 1, specifically, as follows: Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, a sliding cylinder 215 is slidably disposed on the mounting bracket 102, and an inlet / outlet hole 216 is provided on the sliding cylinder 215, and a filter screen 217 is provided on the inlet / outlet hole 216. like Figure 5 and Figure 9 As shown, the filter 217 is located on one side of the connecting pipe 203, so that the outside air enters the output chamber from the connecting pipe 203. The conveying chamber 201 is divided into two chambers by the sliding cylinder 215 and the filter 217. The air in the conveying chamber 201 is filtered by the filter 217, and the filtered air then contacts the sensor 103. This prevents the outside dust from entering the conveying chamber 201, and thus prevents the outside dust from being discharged from the air outlet 207 and coming into contact with the lens of the sensor 103. Furthermore, a fixing ring 218 is provided on the mounting bracket 102, and an inlet / outlet hole 219 is provided on the fixing ring 218. The sliding cylinder 215 is slidably disposed on the fixing ring 218. The inlet / outlet hole 216 and the inlet / outlet hole 219 are adapted to each other. A handle 220 is provided on the sliding cylinder 215. By sliding the handle 220, the handle 220 and the sliding cylinder 215 are disengaged from the fixing ring 218, at which point the sensor 103 is exposed, making it convenient for staff to replace or maintain the sensor 103, and to clean the filter screen 217. By rotating the handle 220, the sliding cylinder 215 rotates along the fixing ring 218, and the sliding cylinder 215 blocks the inlet and outlet holes 219, thereby adjusting the air flow rate discharged from the outlet hole 207. Furthermore, a sliding groove 221 is provided on the sliding cylinder 215, a top moving post 222 is slidably provided on the sliding groove 221, a spring 223 is provided on the corresponding surface of the top moving post 222 and the sliding groove 221, and a semi-circular groove 224 is provided on the fixing ring 218. Furthermore, a ball bearing 225 is rotatably mounted on the push column 222, and the ball bearing 225 is adapted to the semi-circular groove 224; The engagement of the ball bearing 225 and the semi-circular groove 224 positions the sliding cylinder 215 on the fixed ring 218, preventing displacement of the sliding cylinder 215 when air enters the conveying chamber 201. When the handle 220 is turned, the sliding cylinder 215 rotates synchronously, and the ball bearing 225 and the semi-circular groove 224 are in a state of disengagement and engagement. When the ball bearing 225 and the semi-circular groove 224 are disengaged, the push pin 222 and the ball bearing 225 slide synchronously along the sliding groove 221, and the spring 223 is compressed. When the ball bearing 225 and the semi-circular groove 224 are engaged, the elasticity of the spring 223 drives the ball bearing 225 and the semi-circular groove 224 to engage. The usage process of the anti-counterfeiting printing detection device for packaging boxes provided by this invention is as follows: In use, the air pump 202 is started, drawing outside air into the connecting pipe 203. The air is then transferred to the delivery chamber 201 via the connecting pipe 203. The filter 217 filters the air in the delivery chamber 201. The filtered air comes into contact with the sensor 103, and the air flowing through the delivery chamber 201 provides air cooling to the sensor 103. The sensor 103's own heat heats the air. The heated air enters the discharge pipe 208 from the delivery chamber 201, and then enters the hollow base 1 204 and hollow base 2 205 from the discharge pipe 208, finally exiting through the air outlet 207. The hot air exiting through the air outlet 207 heats the lens of the sensor 103, making the surface temperature of the sensor 103 lens higher than that of the ambient air. When the dew point is reached, the motor 209 is started, which drives the drive shaft 210 to rotate. The drive shaft 210 drives the drive gear 211 to rotate, the drive gear 211 drives the transmission gear 212 to rotate, and the transmission gear 212 drives the hollow seat 205 to rotate synchronously. The hollow seat 205 drives the fixed plate 214 to rotate synchronously. At this time, when the air outlet 207 blows air onto the lens of the sensor 103, the air outlet 207 and the hollow seat 205 rotate synchronously. By rotating and blowing air onto the lens of the sensor 103, multi-angle dust removal is achieved. When the packaging box conveyed by the conveying mechanism 101 is not aligned and comes into contact with the fixed plate 214, the rotating fixed plate 214 squeezes the unequal packaging box, causing the unequal packaging box to move to a position that does not interfere with the normal operation of the sensor 103.
