Description

Technical Field

[0001] This utility model relates to the field of barcode scanner technology, and more specifically, to a handheld barcode scanner with multiple replaceable optical filters. Background Technology

[0002] The emergence of barcode scanners stemmed from people's need for fast and accurate data collection. With the development of industries such as logistics, retail, and manufacturing, the original method of manually recording data was not only inefficient, but also prone to deviations due to worker negligence, failing to meet enterprises' requirements for real-time and accurate information. Furthermore, with the development and maturity of laser and computer technology, people combined laser technology with mechanics to invent barcode scanners, which gradually replaced manual data recording. However, most existing barcode scanners can only scan a single type of barcode and cannot recognize different types of barcodes, thus limiting their capabilities.

[0003] A search revealed that publication number CN222167612U discloses a modular handheld barcode scanner, belonging to the field of barcode scanners. This modular handheld barcode scanner includes a handle, a scanner body and a battery compartment respectively disposed at both ends of the handle, and a connecting structure for fixing the scanner body and the battery compartment to the handle. The handle has a switch button. The connecting structure includes locking blocks fixedly installed on the top of the scanner body and the top of the battery compartment, slots at both ends of the handle that mate with the locking blocks, and locking structures at both ends of the handle for locking the locking blocks into the slots. This modular handheld barcode scanner, through its connecting structure, allows for the disassembly and assembly of the handle, scanner body, and battery compartment, avoiding the inconvenience of maintenance associated with a monolithic design and achieving modular assembly and replacement. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] Existing handheld barcode scanners can only scan a specific single type of barcode. In logistics warehouses, when printing barcodes for different types of items, staff need to print different types of barcodes for different items according to statistical needs, so as to facilitate classification. However, the filters on traditional handheld barcode scanners are fixedly installed on the scanning head, which are not easy to disassemble. Moreover, the filter is easily damaged during disassembly, which affects the normal use of the barcode scanner. Therefore, barcode scanners with fixed filter installation are not suitable for changing optical filters to scan different barcodes.

[0005] Therefore, a handheld barcode scanner with multiple replaceable optical filters is proposed to address the above problems. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a handheld barcode scanner with a variety of replaceable optical filters to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a handheld barcode scanner with multiple replaceable optical filters, comprising a filter assembly, a placement assembly, a main body assembly, and a power supply assembly. The main body assembly is mounted on the side of the filter assembly, and the placement assembly is mounted below the main body assembly. The power supply assembly is mounted on the side of the main body assembly away from the filter assembly.

[0008] Preferably, the filter assembly includes an optical filter, a connecting ring, and a permanent magnet, and the connecting ring is mounted on the side of the optical filter, and at least three sets of permanent magnets are equidistantly embedded on the outer diameter surface of the connecting ring, and the surface of the optical filter is coated with an oleophobic nano-coating.

[0009] Preferably, the placement component includes a threaded connecting post, a placement chamber, and a vacuum suction cup. The placement chamber is installed below the threaded connecting post, and the vacuum suction cup is installed below the placement chamber. The vacuum suction cup is made of corrugated soft rubber material, and its bottom surface is provided with a honeycomb micro-suction cup array.

[0010] Preferably, the main component includes a sweeping dock, a connecting iron column, and a connecting component, with the connecting iron column installed on the side of the sweeping dock and the connecting component installed on the side of the sweeping dock away from the connecting iron column.

[0011] Preferably, the power supply assembly includes a card slot block, a card plate, and a rechargeable battery, with the rechargeable battery placed on the upper inner wall of the card slot block and the card plate installed on the side of the card slot block.

[0012] Preferably, the connecting component includes an L-shaped connecting block, a handle, and a limiting strap, with the handle mounted below the L-shaped connecting block and the limiting strap mounted on the side of the handle.

[0013] Preferably, the main body of the grip is an arc-shaped cylindrical structure, and an arc-shaped transition area is cut out on the side of the main body of the grip, and the limiting band and the grip are connected by a ring buckle.

[0014] Preferably, the optical filter and the connecting ring are interference fit, and the optical filter is a standard circular flat plate that conforms to the symmetry characteristics of optical elements, and the center thickness of the optical filter is slightly greater than the edge thickness.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] Compared with existing technologies, this handheld barcode scanner with multiple replaceable optical filters features a magnetic connection between the filter assembly and the main body assembly for easy installation and disassembly. This allows for quick replacement of the optical filters, and the connecting ring protects the filters from damage during long-term use. This allows staff in logistics warehouses to scan different types of barcodes without needing to replace the entire scanner; simply changing the optical filter is sufficient. This saves staff time searching for the correct type of scanner and reduces the cost of purchasing multiple barcode scanners for item sorting.

[0017] Compared with existing technologies, this handheld barcode scanner with multiple replaceable optical filters places different types of optical filters needed for sorting items in the placement component. This eliminates the need for staff to search for specific filter components when sorting and scanning items with different types of barcodes. They can simply remove the filter components from the placement compartment by turning the threaded connecting post and the connection point between the placement compartment and the barcode scanner. This saves time searching for filter components and also makes it less likely for the filter components to be lost when the barcode scanner is not in use. Attached Figure Description

[0023] 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. Example 1

[0024] As attached Figures 1 to 4 The handheld barcode scanner shown includes a filter assembly 1, a placement assembly 2, a main body assembly 3, and a power supply assembly 4. The main body assembly 3 is mounted on the side of the filter assembly 1, the placement assembly 2 is mounted below the main body assembly 3, and the power supply assembly 4 is mounted on the side of the main body assembly 3 away from the filter assembly 1.

[0025] Specifically: When staff in a logistics warehouse use a barcode scanner to scan the barcode on a package to quickly identify the package's destination, tracking number, and other information, thus automating the sorting of the package, they need to remove the filter assembly 1 from the placement assembly 2 and magnetically connect it to the main assembly 3 through the magnetic attraction of the outer diameter surface of the filter assembly 1. Then, by pressing the barcode scanner switch on the main assembly 3, they check whether the power supply assembly 4 is properly connected. If the barcode scanner can be used normally, the staff can hold the main assembly 3 to sort the packages. Example 2

[0026] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0027] In a preferred embodiment, the filter assembly 1 includes an optical filter 5, a connecting ring 6, and a permanent magnet 7. The connecting ring 6 is mounted on the side of the optical filter 5, and at least three sets of permanent magnets 7 are equidistantly embedded on the outer diameter surface of the connecting ring 6. The surface of the optical filter 5 is coated with an oleophobic nano-coating. When the operator installs the filter assembly 1 onto the main body assembly 3, they need to first check whether the connection between the optical filter 5 and the connecting ring 6 is secure to prevent the optical filter 5 from falling off the connecting ring 6 during use. After the check is completed, the operator needs to connect the optical filter 5 and the main body assembly 3 magnetically using the permanent magnets 7.

[0028] In a preferred embodiment, the placement assembly 2 includes a threaded connecting post 8, a placement chamber 9, and a vacuum suction cup 10. The placement chamber 9 is installed below the threaded connecting post 8, and the vacuum suction cup 10 is adhered to the bottom of the placement chamber 9. The vacuum suction cup 10 is made of corrugated soft rubber material, and its bottom surface is provided with a honeycomb micro-suction cup array. When the worker needs to take out the filter assembly 1 from the placement assembly 2 and install it on the main assembly 3 for use, he / she needs to take out the barcode scanner that is adsorbed in the barcode scanner placement chamber by the vacuum suction cup 10, and then open the placement chamber 9 by twisting the connection between the threaded connecting post 8 and the placement chamber 9, and take out the filter assembly 1 from the placement chamber 9.

[0029] In a preferred embodiment, the main body component 3 includes a scanning dock 11, a connecting iron column 12, and a connecting component 13. The connecting iron column 12 is welded to the side of the scanning dock 11, and the connecting component 13 is welded to the side of the scanning dock 11 away from the connecting iron column 12. When the operator needs to install the filter component 1 onto the main body component 3, they need to align the outer diameter surface of the filter component 1 with the connecting iron column 12, and then connect the two by magnetic attraction, so that the filter component 1 is fixed to the outside of the scanning dock 11. When the operator needs to use the main body component 3 to scan the barcode on the object, they need to hold the connecting component 13 by hand to scan the barcode.

[0030] In a preferred embodiment, the power supply assembly 4 includes a slot block 14, a card plate 15, and a rechargeable battery 16. The rechargeable battery 16 is placed on the upper inner wall of the slot block 14, and the card plate 15 is installed on the side of the slot block 14. When the rechargeable battery 16 of the power supply assembly 4 is out of power, the operator needs to push the card plate 15 out from under the slot block 14, then remove the rechargeable battery 16 from the slot block 14, charge it with a charging device, and then remove a spare rechargeable battery 16 and reinstall it into the slot block 14, so as not to delay the operator's work time.

[0031] In a preferred embodiment, the connecting component 13 includes an L-shaped connecting block 17, a handle 18, and a limiting strap 19. The handle 18 is installed below the L-shaped connecting block 17, and the limiting strap 19 is installed on the side of the handle 18. When a worker needs to hold the handle 18 of the connecting component 13 to scan and sort barcodes on objects, he / she needs to hold the curved transition area at the front end of the handle 18 with his / her fingers and pass the limiting strap 19 through his / her palm to prevent the worker from relaxing his / her hand due to work fatigue and not holding the barcode scanner firmly, which could cause it to fall onto hard objects and be damaged. The L-shaped connecting block 17 can connect the handle 18 of the connecting component 13 to other parts of the main component 3.

[0032] As a preferred embodiment, the main body of the grip 18 is an arc-shaped cylindrical structure. An arc-shaped transition area is cut out on the side of the main body of the grip 18, and a layer of silicone coating is bonded to the outer layer of the arc-shaped transition area to reduce the discomfort such as friction and heat experienced by the staff when holding the grip 18 for a long time. The limiting strap 19 and the grip 18 are connected by a ring buckle. The limiting strap 19 is made of nylon, which has good breathability. In order to prevent the staff from feeling too narrow and uncomfortable or too wide and stuffy during long-term use, the inner side of the limiting strap 19 is designed as an arc surface, and the width also conforms to the ergonomic standard.

[0033] In a preferred embodiment, the optical filter 5 and the connecting ring 6 are interference fit. The optical filter 5 is a standard circular flat plate that conforms to the symmetry characteristics of optical elements. The center thickness of the optical filter 5 is slightly greater than the edge thickness. The inner diameter surface of the connecting ring 6 is drilled with a shallow groove, so that the optical filter 5 can be more firmly fixed to the inner side of the connecting ring 6.

[0034] The working process of this utility model is as follows: First, in the logistics warehouse, when the staff uses a barcode scanner to scan the barcode on the package to quickly identify the package's destination, tracking number, and other information, and to achieve automated sorting of the package, they need to take out the barcode scanner that is adsorbed in the barcode scanner placement cavity by the vacuum suction cup 10. Then, by turning the threaded connecting post 8 of the placement component 2 and the connection between the placement chamber 9 and the placement chamber 9, the placement chamber 9 is opened, and the filter component 1 in the placement chamber 9 is taken out. Then, the filter component 1 is installed on the scanning post 11 of the main component 3. Before installation, the staff needs to check whether the optical filter 5 and the connecting ring 6 are securely connected to prevent the optical filter 5 from falling out of the connecting ring 6 during use. After the check is completed, the staff needs to use the permanent magnet 7 to connect the optical filter 5 and the connecting iron post 12 of the main component 3 by magnetic attraction. Then, by pressing the barcode scanner switch on the main component 3, the staff checks whether the connection between the rechargeable battery 16 of the power component 4 and the internal parts of the barcode scanner is good.

[0035] If the barcode scanner cannot scan the barcode on the object when the scanner switch is turned on, the operator needs to push the card plate 15 out from under the card slot block 14, and then remove the rechargeable battery 16 from the card slot block 14. Observe whether the rechargeable battery 16 is damaged. If it is not damaged, the operator needs to charge it with a charging device and take out the spare rechargeable battery 16 and reinstall it into the card slot block 14 to observe whether the barcode scanner can work normally. If it can scan the barcode normally, the operator can hold the handle 18 of the connecting component 13 and use the other hand to assist by passing the limiting strap 19 through their palm to prevent the operator from relaxing their hand due to work fatigue and not holding the barcode scanner firmly, which could cause it to fall onto a hard object and cause damage. The L-shaped connecting block 17 can connect the handle 18 of the connecting component 13 to other parts of the main component 3. The above is the working principle of this handheld barcode scanner with multiple replaceable optical filters.
