Description

Technical Field

[0001] This utility model relates to the field of barcode scanner technology, specifically a positioning component for a barcode scanner. Background Technology

[0002] Barcode scanning devices are now widely used in supermarkets and stores to efficiently process products whose part numbers or prices are encoded using barcodes. However, existing barcode scanners, due to their fixed scanning window size, often struggle to adapt to barcodes of different sizes, shapes, or positions. If the barcode is too large or too small, the scanning window may not completely cover it. During scanning, operators need to precisely adjust the barcode's position and angle, aligning it with the scanning window and maintaining a certain distance to ensure accurate scanning. This not only reduces scanning efficiency but also increases human error and operational complexity.

[0003] The barcode scanning process requires a positioning component of the barcode scanner. A search revealed a patent document with publication number CN221281535U that discloses a positioning component for a barcode scanner, including a scanner host and a positioning cover. The positioning cover has a scanning window in the center, and the interior of the positioning cover is provided with a driving component, a sliding component, a first limiting component, and a second limiting component. The driving component and the sliding component are arranged parallel to each other on both sides of the positioning cover. The first limiting component and the second limiting component are arranged side by side between the driving component and the sliding component.

[0004] However, the positioning component of the barcode scanner has a complex opening and closing mechanism for the scanning window, which is inconvenient to operate. Furthermore, the barcode scanner does not have the function of automatically adjusting the scanning angle, making it difficult to meet the needs of different application scenarios. Therefore, a positioning component for a barcode scanner is proposed to solve the problems mentioned above. Utility Model Content

[0008] The angle adjustment mechanism includes a placement base disposed on the lower surface of the scanner host, a motor fixedly installed outside the placement base, a worm gear fixedly connected to the output shaft of the motor, a rotating shaft rotatably connected inside the placement base and extending to its outside, a worm wheel fixedly connected to one end of the rotating shaft, and a fixing frame fixedly connected to the outside of the rotating shaft.

[0009] Furthermore, the outer diameter of the ring gear is adapted to the inner diameter of the limiting ring, and the lever is oscillatingly connected to the upper surface of the mounting base.

[0010] Furthermore, the adjusting gear and the ring gear mesh with each other, and there are several adjusting gears, racks and baffles, with several baffles arranged in a ring shape on the upper surface of the limiting ring.

[0011] Furthermore, a slider extending into the interior of a limiting ring is fixedly connected to the bottom of the rack, and a sliding groove adapted to the slider is provided inside the limiting ring, and the slider and the sliding groove are slidably connected.

[0012] Furthermore, a limiting seat is fixedly installed inside the mounting base, and the limiting seat has a limiting groove adapted to the rack inside.

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.

[0025] Please see Figures 1 to 5 A positioning component for a barcode scanner in this embodiment includes a scanner host 1 and a positioning cover 2 fixedly installed on the upper surface of the scanner host 1. The upper surface of the positioning cover 2 is provided with an opening and closing structure, and the lower surface of the scanner host 1 is provided with an angle adjustment mechanism. The opening and closing structure includes a mounting base 3 fixedly connected to the upper surface of the positioning cover 2, a limiting ring 4 fixedly connected to the upper surface of the mounting base 3, a ring gear 5 rotatably connected to the inside of the limiting ring 4, a lever 6 fixedly connected to the outside of the ring gear 5, an adjusting gear 7 rotatably connected to the upper surface of the mounting base 3, a rack 8 meshing with the outside of the adjusting gear 7, and a baffle plate 9 fixedly connected to the upper surface of the rack 8.

[0026] The outer diameter of the ring gear 5 is matched with the inner diameter of the limiting ring 4, and the lever 6 is oscillatingly connected to the upper surface of the mounting base 3.

[0027] Specifically, the adjusting gear 7 and the ring gear 5 mesh with each other. There are several adjusting gears 7, racks 8, and baffles 9, arranged in a ring shape on the upper surface of the limiting ring 4. By manually rotating the lever 6, the rotation of the ring gear 5 can be precisely controlled, driving the adjusting gear 7. The rotation of the adjusting gear 7 drives the linear motion of the rack 8, which in turn moves the baffles 9, achieving precise position control of the baffles 9. This allows the opening and closing structure to adapt to various working conditions, thereby adjusting the size of the scanning area of ​​the scanning window, improving the versatility and applicability of the equipment, and achieving high scanning accuracy.

[0028] It should be noted that a slider extending into the limiting ring 4 is fixedly connected to the bottom of the rack 8. The limiting ring 4 has a groove 11 that matches the slider, and the slider and the groove 11 are slidably connected. A limiting seat 10 is fixedly installed inside the mounting base 3. The limiting seat 10 has a limiting groove that matches the rack 8.

[0029] In this embodiment, the angle adjustment mechanism includes a placement base 12 disposed on the lower surface of the scanner host 1, a motor 13 fixedly mounted outside the placement base 12, a worm gear 14 fixedly connected to the output shaft of the motor 13, a rotating shaft 15 rotatably connected inside the placement base 12 and extending to its outside, a worm wheel 16 fixedly connected to one end of the rotating shaft 15, and a fixing bracket 17 fixedly connected to the outside of the rotating shaft 15. By starting the motor 13 with the controller, the worm gear 14 is driven to rotate, thereby driving the worm wheel 16 and the rotating shaft 15 to rotate. This enables high-precision angle adjustment, ensuring that the scanner host 1 can adjust the angle in minute steps, meeting the user's needs for precise scanning angles.

[0030] The worm 14 and worm wheel 16 are meshed with each other, and the bearing adapted to the rotating shaft 15 is fixedly installed inside the mounting base 12.

[0031] Specifically, the mounting bracket 17 is in the shape of an inverted U-shape, and the scanner host 1 is fixedly installed on the upper surface of the mounting bracket 17 and rotatably connected to the upper surface of the placement base 12.

[0032] The working principle of the above embodiments is as follows:

[0033] In use, the angle adjustment mechanism is installed at the position where the barcode needs to be scanned. When scanning a barcode, the rotation of the manually driven lever 6 can precisely control the rotation of the ring gear 5, which in turn drives the adjusting gear 7. The rotation of the adjusting gear 7 drives the linear motion of the rack 8, which in turn moves the baffle 9, achieving precise position control of the baffle 9. This allows the opening and closing structure to adapt to various working conditions, thereby achieving the purpose of adjusting the size of the scanning area of ​​the scanning window. The controller starts the motor 13, which drives the worm gear 14 to rotate, thereby driving the worm wheel 16 and the rotating shaft 15 to rotate. This enables high-precision angle adjustment, ensuring that the scanner host 1 can adjust the angle in small steps to meet the user's needs for precise scanning angles.

[0034] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
