Detailed Implementation

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] like Figures 1-9 As shown, this embodiment provides a modular intelligent barcode scanning control system for logistics transmission lines, including a stand 10, a support component 20, a barcode scanning component 30, a supplementary lighting component 40, a sensor component 50, an electronic box component 60, and a human-machine interaction component 70.

[0020] The support 10 includes a base plate 11, a top plate 12 parallel to and spaced above the base plate 11, and side plates 13 fixed to the base plate 11 and supporting the top plate 12. The base plate 11, top plate 12, and side plates 13 cooperate to accommodate space.

[0021] To facilitate transfer, self-locking casters can be provided below the base plate 11. These can be conventionally designed in the art and will not be described in detail in this embodiment.

[0022] The support assembly 20 is fixed to the stand 10, and includes a support rod 21 and a first mounting member 22 and a second mounting member 23 mounted on the support rod 21.

[0023] The bottom end of the support rod 21 is fixed to the base plate 11, and the top end protrudes from the top plate 12. The support rod 20 is a telescopic rod structure. In this embodiment, the support rod 21 includes a lower rod 211 and an upper rod 212. The lower rod 211 is fixed to the base plate 11. The bottom of the upper rod 212 is inserted into and limited within the lower rod 211, and the top is suspended. The upper rod 212 can move up and down to adjust the overall height of the support rod 21.

[0024] The first mounting component 22 and the second mounting component 23 are both mounted on the upper rod 212. Adjusting the height of the support rod 21 can change the height of the first mounting component 22 and the second mounting component 23.

[0025] The first mounting component 22 and the second mounting component 23 have the same structure, both including a ring and a back claw. The ring is fitted onto the upper rod 212, and the back claw is fixed to the ring for mounting other components. The ring is movably connected to the upper rod 212, allowing for fine-tuning of the positions of the first mounting component 22 and the second mounting component 23 by adjusting the position of the ring up and down. Specifically, the ring can be fastened to the upper rod 212 with screws; loosening the screws allows for up-and-down adjustment of the ring's position.

[0026] The scanning component 30 is mounted on the support component 20 and includes a housing 31, a package scanning camera 32, a label scanning camera 33, and a barcode scanning camera 34.

[0027] The encapsulation housing 31 is fixed to the back claw of the first mounting member 22, and the encapsulation housing 31 forms a storage space, in which the package scanning camera 32, the tag scanning camera 33, and the barcode scanning camera 34 are all housed. It is understood that as the height of the support rod 21 is adjusted and / or the position of the loop of the first mounting member 22 is adjusted, the installation height of the barcode scanning component 30 will also change synchronously to meet the different height requirements of the barcode scanning component 30 in different scenarios.

[0028] To fulfill the shooting function, the encapsulation housing 31 also needs to be provided with a shooting window 310 so that the shooting ends of the package scanning camera 32, the label scanning camera 33 and the barcode scanning camera 34 are exposed.

[0029] The encapsulation housing 31 includes a bottom shell 311 and a front cover 312. The bottom shell 311 has an opening on the side facing the front cover 312, and the front cover 312 covers the opening of the bottom shell 311. The front cover 312 is detachably connected to the bottom shell 311 to facilitate the debugging and maintenance of the barcode scanner 32, bag scanner 33, and label scanner 34 installed in the receiving space. In this embodiment, the front cover 312 is a flip-top structure. Its bottom is connected to the bottom shell 311 by a hinge, and its top is connected to the bottom shell 311 by a snap fastener. To open the front cover 312, the snap fastener is pulled from the top to separate the top of the front cover 312 from the bottom shell 311, and then the front cover 312 can be opened by folding it around the hinge.

[0030] The bag scanning camera 32, the label scanning camera 33, and the barcode scanning camera 34 are all connected to the bottom shell 311, for example, they can be connected to the bottom wall or side wall of the bottom shell 311 via connectors; the shooting window 310 is located on the face cover 312, connecting the storage space to the outside. Light from the object to be photographed enters the storage space through the shooting window 310 and is captured by the barcode scanning camera 32, the bag scanning camera 33, and the label scanning camera 34. From the normal use position, the face cover 312 is located on the side of the packaging shell 31 facing away from the object to be photographed.

[0031] Specifically, in this embodiment, the package scanning camera 32 and the label scanning camera 33 are connected to the bottom shell 311 via a first fixing member 35; the barcode scanning camera 34 is connected to the bottom shell 311 via a second fixing member 36. The barcode scanning camera 34 is located on the central axis of the packaging shell 31, and the package scanning camera 32 and the label scanning camera 33 are located above the barcode scanning camera 34 and are symmetrically arranged about the central axis of the packaging shell 31. The above installation position avoids occupying space in one direction, allowing the packaging shell 31 to be designed with a smaller structure, which is beneficial for controlling production costs.

[0032] Furthermore, the scanning component 30 also includes an adjustment device 37, which is used to adjust the horizontal orientation of the package scanning camera 32 and the tag scanning camera 33.

[0033] The adjusting device 37 includes a driven gear 371, a driving gear 372, an adjusting nut 373, and a spring 374.

[0034] There are two driven gears 371, which are fixed one-to-one with the package scanning camera 32 and the label scanning camera 33. The two driven gears 371 are horizontally spaced to form an assembly gap 375. The driving gear 372 is suspended above the assembly gap 375. The adjusting nut 373 includes a head 3731 and a rod 3732 connected to each other. The head 3731 is exposed outside the packaging housing 31. One end of the rod 3732 is fixed to the head 3731, and the other end passes through the packaging housing 31 and connects to the driving gear 372. 72 is fixed; the adjusting nut 373 is used to drive the driving gear 372 into the assembly gap 375 and mesh with the two driven gears 371. Rotating the adjusting nut 373 drives the two driven gears 371 to rotate. The package scanning camera 32 and the label scanning camera 33 are each movably connected to the first fixing member 35 through a first pin. The rotation of the driven gears 371 drives the package scanning camera 32 and the label scanning camera 33 to rotate around their respective first pins, changing the horizontal orientation of the package scanning camera 32 and the label scanning camera 33. Since the package scanning camera 32 and the label scanning camera 33 are controlled by the same driving gear 371, the package scanning camera 32 and the label scanning camera 33 can be adjusted synchronously, reducing the operation steps, and their movement directions are consistent.

[0035] The spring 374 is clamped between the head 3731 and the packaging housing 31. During the pressing down of the adjusting nut 373, the spring 374 is compressed. After the downward pressure on the adjusting nut 373 is removed, the spring 374 returns to its original position, driving the adjusting nut 373 back to its initial position. This causes the drive gear 372 to disengage from the assembly gap 375, preventing accidental operation of the adjusting nut 373. The package scanning camera 35 and the label scanning camera 36 maintain their current orientation. To adjust again, simply repeat the above adjustment process.

[0036] The supplementary lighting component 40 is mounted on the barcode scanning component 30 and includes a supplementary lighting bracket 41 and a flicker-free lamp 42.

[0037] The supplementary lighting bracket 41 is mounted above the encapsulation housing 31 and is used to mount the flicker-free lamp 42. Specifically, the supplementary lighting bracket 41 has a U-shaped structure, including a fixed base plate 411 fixed to the encapsulation housing 31 and two cantilever arms 412 disposed at both ends of the fixed base plate 411 and extending upward. The two ends of the flicker-free lamp 42 are respectively hinged to the two cantilever arms 412 by second pins, so that the flicker-free lamp 42 can rotate around the hinge point to change the pitch angle of the flicker-free lamp 42. In order to achieve the purpose of position holding, the second pin can be used with an interference fit with the cantilever arm 412, or an additional damping structure can be added. These are existing technologies in the art, and will not be described in detail in this embodiment.

[0038] The flicker-free lamp 42 is used for supplemental lighting to ensure that the package scanning camera 32, the tag scanning camera 33, and the barcode scanning camera 34 can capture clear and bright images when operating at high frame rate and low shutter speed.

[0039] The sensor assembly 50 is mounted on the barcode scanning assembly 30 and includes a sensor bracket 51, a trigger sensor 52, and a laser pointer 53.

[0040] The sensor bracket 51 is mounted above the encapsulation housing 31 and in front of the supplementary lighting bracket 41, and is used to mount the trigger sensor 52. Specifically, the sensor bracket 51 includes a fixed base plate 511 mounted on the encapsulation housing 31, a fixed top plate 512 parallel to and spaced from the fixed base plate 511, and two fixed side plates 513 disposed at both ends of the fixed base plate 511 and connecting the fixed base plate 511 and the fixed top plate 512. The two ends of the trigger sensor 52 are respectively hinged to the two fixed side plates 513 by two third pins, so that the trigger sensor 52 can rotate around the hinge point to change the pitch angle of the trigger sensor 52. In order to achieve the purpose of position holding, the third pins can be used with an interference fit with the fixed side plates 513, or a damping structure can be added. These are existing technologies in the art, and will not be described in detail in this embodiment.

[0041] To facilitate the adjustment of the pitch angle of the trigger sensor 52, a knob 514 can be provided. Any of the third pins passes through the fixed side plate 513 and is fixed to the knob 514. By rotating the knob 514, the rotation of the trigger sensor 52 can be driven, thereby achieving fine adjustment.

[0042] The laser pointer 53 is fixed to the trigger sensor 52, ensuring that their motion states remain consistent. The head plane of the laser pointer 53 is flush with the head plane of the trigger sensor 52. The relative positions of the laser pointer 53 and the trigger sensor 52 remain fixed. The laser pointer 53 emits a laser beam, and the projection position of the laser point reflects the sensing direction of the trigger sensor 52, which can effectively assist the trigger sensor 52 in positioning its sensing direction.

[0043] Furthermore, a fourth pin can be provided below the fixed base plate 511. The fourth pin is movably connected to the encapsulation housing 31. By manually rotating the sensor bracket 51, the fourth pin can be driven to rotate, changing the overall horizontal orientation of the sensor assembly 50, thereby adjusting the horizontal orientation of the trigger sensor 52 and the laser pointer 53.

[0044] The package scanning camera 32 is used to identify the cigarette pack 90, the label scanning camera 33 is used to identify the label 91 on the cigarette pack 90, and the barcode scanning camera 34 is used to identify the QR code 911 on the label 91. All three identification processes described above belong to existing image recognition technologies in this field, and will not be elaborated upon in this embodiment.

[0045] The label 91 is sewn onto the center of the short side of the cigarette pack 90 by hemp rope. The label 91 has two holes for the hemp rope to pass through, located at both ends of the label 91, so that both ends of the label 91 can be fixed by the hemp rope, which facilitates the flat unfolding of the label 91 for easy scanning of the label and QR code.

[0046] The electrical enclosure assembly 60 is disposed within the receiving space and fixed to the support assembly 20, allowing the electrical enclosure assembly 60 to be well concealed within the stand 10. The electrical enclosure assembly 60 includes a housing and a circuit board. The circuit board is installed within the housing and integrates electrical components such as a processor, communication module, and power module, used to supply power to and control the operation of the barcode scanning assembly 30, the supplementary lighting assembly 40, and the sensor assembly 50. The main control principle is as follows: Before use, the flickerless light 42 is turned on to provide supplementary lighting. After the trigger sensor 52 detects the cigarette pack, it triggers a scanning signal and sends it back to the processor. The processor then controls the pack scanning camera 32, the tag scanning camera 33, and the barcode scanning camera 34 to start scanning. The information obtained from the scanning is fed back to the processor, and the scanning result is generated after being processed by the image processing algorithm built into the processor.

[0047] The human-computer interaction component 70 includes a display 71, an alarm light 72, and an alarm horn 73. All three components are electrically connected to the processor. The display 71 shows the scanning result, and the alarm light 72 and alarm horn 73 output color and voice prompts based on the scanning result. The display 71 is mounted on the support component 20, specifically, it is fixed to the back claw of the second mounting member 23. It is understood that as the height of the support rod 21 is adjusted and / or the position of the loop of the second mounting member 23 is adjusted, the mounting height of the display 71 will also change synchronously to meet the different height requirements of the display 71 in different scenarios.

[0048] In addition, the human-computer interaction component 70 may also include external input or output devices such as a mouse, keyboard, gamepad, or handwriting screen to input control commands to the processor or output operating data. Conventional techniques in the field can be used, and this embodiment will not elaborate on them.

[0049] During the circuit layout process, the support rod 21 can be selected as a hollow pipe. The cable enters the hollow area of ​​the support rod 21 directly from the electrical box assembly 60, and exits after reaching the location of the barcode scanning assembly 30. Using the hollow area of ​​the support rod 21 as the wiring path can reduce the exposure of the cable, maintain the aesthetic appearance, protect the cable, and extend the service life of the cable.

[0050] The workflow of the modular intelligent barcode scanning control system for logistics transmission lines provided by this utility model is as follows: (1) Before the cigarette pack 90 is put into or taken out of the warehouse, the double-hole label 91 is sewn onto the center of the short side of the cigarette pack 90 using hemp rope. During the sewing process, the label 91 is kept flat and unfolded. (2) Unlock the casters, push the entire device to a suitable position on one side of the cigarette pack logistics conveyor line, and then lock the casters to restrict the movement of the device; (3) Adjust the height of the support rod 21 so that the optical axis of the barcode camera 34 is aligned with the center of the cigarette pack on the logistics conveyor line, and the height of the display 71 is convenient for human eyes to observe. (4) Power on the device and observe the imaging of the package scanning camera 32, the label scanning camera 33, and the barcode scanning camera 34 on the display 71. Adjust the focal length and aperture of the barcode scanning camera 34 automatically through the software, and manually adjust the focal length and aperture of the package scanning camera 32 and the label scanning camera 33 until a clear and bright image is displayed on the display 71. (5) Adjust the scanning camera 32 and the tag scanning camera 33 to rotate 15° toward the direction of the incoming package, and adjust the trigger sensor 52 to rotate 20° toward the direction of the incoming package. Adjust the pitch angle of the trigger sensor 52 according to the laser point indication so that the laser point hits the center position of the cigarette pack 90 on the logistics conveyor line. (6) The logistics conveyor line is started and runs at a speed of 0.6 m / s. When the cigarette pack 90 passes the laser point projected by the laser pointer 53, the sensor is triggered to detect that a cigarette pack has passed by. The alarm horn announces "pack" and triggers the package scanning camera 32, the tag scanning camera 33, and the barcode scanning camera 34 to take pictures. (7) When the decoding calculation is successful, the alarm horn will announce "passed"; when the label scanning camera 33 detects the label and the decoding calculation fails, the alarm horn will announce "code abnormal". At this time, the processor controls the frequency converter on the logistics conveyor to slow down the logistics conveyor to 0.3m / s. The worker uses a handheld barcode scanner to scan the code. After the scan is completed, the worker presses the "confirm" button on the remote control and the logistics conveyor resumes its running speed of 0.6m / s; when the package scanning camera 32 detects the cigarette pack and the label scanning camera 33 does not detect the label, the alarm horn will announce "code lost". At this time, the processor controls the frequency converter to slow down the logistics conveyor to 0.1m / s. The worker manually hangs the label on the cigarette pack and scans the code with a handheld barcode scanner. After the scan is completed, the worker presses the "confirm" button on the remote control and the logistics conveyor resumes its running speed of 0.6m / s.

[0051] The embodiments of the present utility model have been described above with reference to the accompanying drawings. However, the present utility model is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present utility model without departing from its spirit, and all of these forms are within the protection scope of the present utility model.
