Description

Technical Field

[0001] This utility model relates to the field of product packaging technology, specifically a barcode reader for product packaging. Background Technology

[0002] Barcode readers can automatically and quickly scan barcodes or QR codes on product packaging without requiring manual input of information, greatly saving time, improving packaging and inspection speed on the production line, avoiding errors that may occur with manual barcode reading, such as misreading or mis-entering information, and ensuring the accuracy and consistency of product information reading.

[0003] A relevant reference is Chinese utility model patent CN222927049U, which discloses a box-shaped barcode reader device. This device includes a first transport line and a second transport line arranged sequentially on a barcode reader support; two guide plates and multiple non-standard products located at the starting point of the first transport line; an arrangement assembly located above the first transport line; and a barcode reader located above the second transport line. The two guide plates are slidably connected to the barcode reader support and abut against the multiple non-standard products. The arrangement assembly is used to sequentially arrange the multiple non-standard products on the first transport line for transport. The first transport line sequentially transports individual non-standard products to the second transport line. The barcode reader is used to read the QR codes on the non-standard products transported on the second transport line. This utility model solves the problem of time-consuming and labor-intensive QR code detection and input for non-standard products.

[0004] The aforementioned barcode reading device lacks a guiding structure, which can lead to situations where the printed code on the packaging is not on the same side as the lens of the reading device, resulting in the inability to recognize the printed code. Additionally, the angle deviation can cause the gap between the barcode graphics captured by the lens to be too small, leading to recognition errors. Furthermore, the aforementioned barcode reading device lacks a supplementary lighting component, which can cause recognition errors due to insufficient light during the barcode reading process. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a barcode reader for product packaging, which solves the problems of recognition effect affected by the deviation between the coding surface and the camera's pointing direction, as well as the problem of recognition being affected by excessively low light.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A barcode reader for product packaging includes a conveyor belt, and a barcode reading mechanism is disposed above the conveyor belt.

[0007] The identification component includes a fixed frame disposed above a conveyor belt, a pressure bearing fixedly mounted above the fixed frame, a transmission tube fixedly mounted above the pressure bearing, a movable frame fixedly mounted at the lower end of the transmission tube, connecting frames fixedly mounted at both ends of the movable frame, and a camera module fixedly mounted inside the connecting frame.

[0008] The drive component, located above the recognition component, is used to drive the transmission tube to rotate and adjust the position of the camera module;

[0009] The supplementary lighting components are located on both sides of the recognition components to enhance the brightness of the packaging surface.

[0010] Preferably, the top of the fixing frame is provided with an opening structure, the top of the transmission tube is provided with an annular protrusion structure, and the bottom of the protrusion structure is fixedly connected to the top of the pressure bearing.

[0011] Preferably, the transmission tube passes through the top of the fixed frame and forms a rotatable connection with the fixed frame. The movable frame is fixedly installed on the outside of the bottom end of the transmission tube. The camera module is mirror-symmetrically installed on the left and right ends of the movable frame through the connecting frame. The camera module is also fixedly installed on the bottom center of the support frame.

[0012] Preferably, the drive assembly includes a limiting frame fixedly installed on the top of the fixed frame, a drive motor fixedly installed below the limiting frame, a gear fixedly installed at the bottom end of the drive motor shaft, and a gear ring fixedly installed on the top of the transmission tube.

[0013] Preferably, the limiting frame is located on the left side of the center of the fixed frame, the drive motor is fixed to the left front of the transmission tube through the limiting frame, and the gear and the gear ring mesh with each other.

[0014] Preferably, the supplementary lighting component includes lamp panels fixedly installed on both sides of the fixed frame, a diffuser fixedly installed on the front side of the lamp panels, a light shield fixedly installed on one side of the connecting frame, a diffuser fixedly installed at the four corners of the light shield, and a reflector fixedly installed at the bottom of the movable frame.

[0015] Beneficial effects

[0016] This utility model provides a barcode reader for product packaging. Compared with the prior art, it has the following advantages:

[0017] (1) The barcode reader for product packaging uses a transmission tube to drive a gear to rotate via a drive motor. The gear drives the gear ring to rotate. The gear ring is fixed to the top of the transmission tube. When the gear ring rotates, it can drive the transmission tube to rotate and drive the bottom movable frame to rotate to adjust the position of the camera module. The camera module is also fixedly installed at the bottom center of the support frame. This method allows the camera module to move around the product by adjusting its position. After recognizing the barcode, the drive motor reverses to reset the camera module, thereby reading the barcode on the outer facade of the product and preventing the product from tilting and affecting the recognition effect.

[0018] (2) The barcode reader for product packaging, through the setting of the light panel, can emit light. The soft light cover can soften the light through scattering and diffuse reflection to prevent the packaging surface from reflecting light, thereby supplementing the product surface on the left and right sides. The light shield can prevent the light emitted by the soft light from affecting the imaging of the camera module. The soft light is fixed to one side of the connecting frame through the light shield and can move with the connecting frame to supplement the light in the direction pointed by the camera module. The reflector can reflect the light to the top of the product to supplement the light of the camera module at the bottom of the support frame. This method can improve the brightness of the outer side of the packaging to improve the recognition of the barcode by the camera module. Attached Figure Description

[0025] 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.

[0026] Please see Figure 1-5 This utility model provides a technical solution: a barcode reader for product packaging includes a conveyor belt 1, and a barcode reading mechanism 2 is arranged above the conveyor belt 1.

[0027] The identification component 21 includes a fixed frame 211 disposed above the conveyor belt 1. A pressure bearing 212 is fixedly installed above the fixed frame 211. A transmission pipe 213 is fixedly installed above the pressure bearing 212. A movable frame 214 is fixedly installed at the lower end of the transmission pipe 213. A connecting frame 215 is fixedly installed at both ends of the movable frame 214. A camera module 216 is fixedly installed inside the connecting frame 215. The top of the fixed frame 211 is provided with an opening structure. The top of the transmission pipe 213 is provided with an annular protrusion structure, and the bottom of the protrusion structure is fixedly connected to the top of the pressure bearing 212. The transmission pipe 213 passes through the top of the fixed frame 211 and forms a rotatable connection with the fixed frame 211. The movable frame 214 is fixedly installed on the outside of the bottom end of the transmission pipe 213. The camera module 216 is mirror-symmetrically installed on the left and right ends of the movable frame 214 through the connecting frame 215. The camera module 216 is also fixedly installed at the center bottom end of the support frame 217.

[0028] Specifically, the conveyor belt 1 can transport the product to the area below the barcode reading mechanism 2. The fixed frame 211 can restrict the position of the transmission tube 213. The annular protrusion at the top of the transmission tube 213 prevents the transmission tube 213 from slipping. A pressure bearing 212 is provided between the annular protrusion structure of the transmission tube 213 and the contact surface of the fixed frame 211 to reduce the friction between the transmission tube 213 and the fixed frame 211 when rotating. The movable frame 214 can position the camera module 216 on both sides of the conveyor belt 1 to prevent the camera module 216 from blocking the product movement. The connecting frame 215 has a circular opening structure at the center to fix the camera module 216 while avoiding obstructing the camera module 216 from recognizing the barcode.

[0029] The drive assembly 22 is positioned above the recognition assembly 21 to drive the transmission tube 213 to rotate and adjust the position of the camera module 216. The drive assembly 22 includes a limiting frame 221 fixedly installed on the top of the fixing frame 211. A drive motor 222 is fixedly installed below the limiting frame 221. A gear 223 is fixedly installed at the bottom of the shaft of the drive motor 222. The drive assembly 22 also includes a gear ring 224 fixedly installed on the top of the transmission tube 213. The limiting frame 221 is located on the left side of the center of the fixing frame 211. The drive motor 222 is fixed to the left front of the transmission tube 213 through the limiting frame 221. The gear 223 and the gear ring 224 mesh with each other.

[0030] Specifically, the limiting frame 221 can limit the position of the drive motor 222. The drive motor 222 drives the gear 223 to rotate, which in turn drives the gear ring 224 to rotate. The gear ring 224 is fixed to the top of the transmission tube 213. When the gear ring 224 rotates, it can drive the transmission tube 213 to rotate, and drive the bottom movable frame 214 to rotate to adjust the position of the camera module 216.

[0031] The supplementary lighting components 23 are disposed on both sides of the recognition component 21 to enhance the brightness of the packaging surface.

[0032] The supplementary lighting assembly 23 includes a lamp plate 231 fixedly installed on both sides of the mounting frame 211, a diffuser 232 fixedly installed on the front side of the lamp plate 231, a light shield 233 fixedly installed on one side of the connecting frame 215, a diffuser 234 fixedly installed at the four corners of the light shield 233, and a reflector 235 fixedly installed at the bottom of the movable frame 214.

[0033] Specifically, the light panel 231 can emit light, the diffuser 232 can soften the light through scattering and diffuse reflection to prevent reflection on the packaging surface, the light shield 233 can prevent the light emitted by the soft light 234 from affecting the imaging of the camera module 216, the soft light 234 is fixed to one side of the connecting frame 215 through the light shield 233 and can move with the connecting frame 215 to provide supplementary light to the direction pointed by the camera module 216, and the reflector 235 can reflect light to the top of the product to provide supplementary light to the camera module 216 at the bottom of the support frame 217.

[0034] Specifically, the camera module 216 is model FCB-4K, the drive motor 222 is model HSS0604A, and the soft light 234 is model JH-120WWW14G40-Z1. In addition, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] During operation, the drive motor 222 drives the gear 223 to rotate, which in turn drives the gear ring 224 to rotate. The gear ring 224 is fixed to the top of the transmission tube 213. When the gear ring 224 rotates, it drives the transmission tube 213 to rotate, which in turn drives the bottom movable frame 214 to rotate, thereby adjusting the position of the camera module 216. The camera module 216 is also fixedly installed at the bottom center of the support frame 217. This method allows the camera module 216 to move around the product by adjusting its position. After recognizing the barcode, the drive motor 222 reverses to reset the camera module 216, thus reading the barcode on the outer facade of the product and preventing the product from tilting and affecting the recognition effect. Plate 231 emits light, and diffuser 232 softens the light through scattering and diffuse reflection to prevent glare on the packaging surface, thereby providing supplementary lighting to the product surface on both sides. Light shield 233 prevents the light emitted by soft light 234 from affecting the imaging of camera module 216. Soft light 234 is fixed to one side of connecting frame 215 through light shield 233 and can move with connecting frame 215 to provide supplementary lighting to the direction pointed by camera module 216. Reflector 235 reflects light to the top of the product to provide supplementary lighting to camera module 216 at the bottom of support frame 217. This method can increase the brightness of the outer side of the packaging to improve the recognition of barcode by camera module 216.
