Description

Technical Field

[0001] The present invention relates to the technical field of industrial identification equipment, and in particular to a barcode scanning device. Background Art

[0002] At present, barcode scanning devices are widely used in supermarkets, logistics, industrial identification and other fields. The implementation of barcode scanning technology is generally based on digital image acquisition and processing. The barcode image of the identified object is acquired by a digital camera element, and after image processing and decoding, it is recognized as a digital signal that can be directly accepted by the computer.

[0003] Barcode scanning devices are generally divided into handheld barcode scanning devices (barcode scanning guns), fixed barcode scanning devices and mobile barcode scanning devices. Barcode scanning guns are relatively traditional barcode scanning devices. Barcode scanning guns are connected to the cash register on the cash register counter through a connecting line. The cashier holds the barcode scanning gun, aligns the gun head with the barcode on the product, presses the switch on the barcode scanning gun, and the barcode scanning gun can scan the barcode on the product, so that the name, weight, price and other information of the product will appear on the cash register.

[0004] With the rapid development of the big data industry, mobile barcode scanning devices based on intelligent communication devices have been more and more widely used in many industries. Generally, the barcode scanning engine is integrated with mobile communication devices such as smart phones, PDAs, tablet computers, etc. When the barcode scanning engine obtains barcode information, the data can be transmitted instantly. In most cases, mobile barcode scanning devices are used directly as portable devices, but in some cases, such as cashiering, inventory counting, material control, etc., continuous and frequent barcode scanning is required, because the triggering of the barcode scanning engine is generally set on the keyboard of the mobile device, or through the touch screen button, which is not particularly convenient to use. In such cases, it is often necessary to configure a handle for the mobile barcode scanning device, and configure the mobile barcode scanning device and the handle into a handheld barcode scanning device, which is much more convenient to use. However, in the case of long-term use, such as when a supermarket cashier scans the barcode for many customers continuously, or when a stocker scans the barcode for goods, long-term operation will cause the user's hands to be too tired or even numb.

Therefore, they cannot be understood as limitations on the present invention.

[0021] See also Figure 1-Figure 4 , Figure 1 It is a three-dimensional schematic diagram of a code scanning device according to an embodiment of the present invention; Figure 2 for Figure 1 A schematic diagram of the assembled code scanning device in FIG. Figure 3 for Figure 2 A schematic diagram of another angle of the code scanning device in FIG. Figure 4 for Figure 1 The present invention provides a code scanning device, which includes a code scanning device body 1 and a handle structure 2. A Hall sensor 11 is installed on the code scanning device body 1. The Hall sensor is a magnetic field sensor made according to the Hall effect.

[0022] Please also see Figure 5 and Figure 6 , Figure 5 It is a schematic diagram of the code scanning device of the present invention when it is not working; Figure 6 The handle structure 2 includes a mounting portion 3 and a gripping portion 4 connected to each other, wherein the mounting portion 3 is used to detachably mount and accommodate the barcode scanner body 1, and the gripping portion 4 is used to be held by a user, and the gripping portion has a cavity 41 therein, and a cantilever structure 5 is disposed in the cavity 41.

[0023] Specifically, the cantilever structure 5 includes a trigger button 51, a cantilever beam connecting rod 52, a magnet 53 and a magnet fixing rod 54. The trigger button 51 is arranged on the grip portion 4, and the first portion 511 of the trigger button 51 protrudes from the grip portion 4, and the second portion 512 of the trigger button 51 is located in the cavity 41. The first portion 511 of the trigger button 51 protrudes from the grip portion 4 to facilitate the user to manually press the trigger button 51. The cantilever beam connecting rod 52 is movably arranged in the cavity 41, and the second portion 512 of the trigger button 51 abuts against the cantilever beam connecting rod 52.

[0024] The magnet fixing rod 54 is used to fix the magnet 53 , and the magnet fixing rod 54 is fixedly connected to the connecting portion of the cantilever beam connecting rod 52 .

[0025] Among them, when the trigger button 51 is not pressed, the magnet 53 is away from the Hall sensor 11, at this time, the Hall sensor 11 of the code scanning device is turned off, and the code scanning device is in a non-working state; when the trigger button 51 is pressed, since the second part 512 of the trigger button 51 abuts against the cantilever beam connecting rod 52, the trigger button 51 will drive the connecting part of the cantilever beam connecting rod 52 to move in the first direction F1, and the connecting part of the cantilever beam connecting rod 52 will then drive the magnet fixing rod 52 to move in the first direction F1 to correspond to the Hall sensor 11 to activate the Hall sensor 11, and the code scanning device is in a working state.

[0026] For details, please refer to Figure 5 The cantilever beam connecting rod 52 has a first end 521 and a second end 522 opposite to each other, the first end 521 and the second end 522 are both movable free ends, the first end 521 abuts against the second portion 512 of the trigger button 51, and the second end 522 is fixedly connected to the magnet fixing rod 54. Moreover, in the present embodiment, the first end 521 and the second end 522 of the cantilever beam connecting rod 52 are both free ends, and a rotation axis 55 is provided in the area between the first end 521 and the second end 522 of the cantilever beam connecting rod 52, so that the cantilever beam connecting rod 52 can rotate around the rotation axis 55. When the trigger button 51 is pressed, the second portion 512 of the trigger button 51 abutting against the cantilever beam connecting rod 52 will squeeze and push the first end 521 of the cantilever beam connecting rod 52 to move in the second direction F2 (for example, to the right along the drawing), as shown in FIG. Figure 5 As described, the second end 522 (connecting portion) of the cantilever beam connecting rod 52 moves in the first direction F1 (for example, to the left along the drawing), that is, the cantilever beam connecting rod 52 rotates around the rotating shaft 55. During this process, the cantilever beam connecting rod drives the magnet fixing rod to move in the first direction F1 to correspond to the Hall sensor 11 to activate the Hall sensor.

[0027] In another embodiment, the cantilever beam connecting rod 52 may not adopt a rotating structure. For example, a slide groove is provided in the cavity 41, and the cantilever beam connecting rod 52 is slidably provided in the slide groove, and the sliding direction of the slide groove is consistent with the first direction. In this way, the purpose of triggering the Hall sensor can also be achieved by installing a magnet on the magnet fixing rod and then bringing the magnet close to the Hall sensor. However, it should be noted that although Figure 5 and Figure 6In the figure, the Hall sensor 11 in the scanner body 1 is arranged on the left side of the magnet 53 (with the figure as a reference), but in fact it can be arranged according to actual needs.

[0028] In addition, in order to facilitate the combination and disassembly of the barcode scanner body 1 and the mounting portion 3, a first fixing member 12 is also provided on the barcode scanner body 1, and correspondingly, a second fixing member is provided on the mounting portion 3, and the first fixing member 12 and the second fixing member are detachably connected. In this embodiment, the first fixing member 12 is provided on the bottom 14 of the barcode scanner body 1, and the second fixing member is provided on the mounting surface 32 (bottom surface) of the mounting portion 3. After the first fixing member 12 is combined with the second fixing member, the first fixing member 12 protrudes from the side of the mounting portion 3 facing away from the barcode scanner body 1, so that it is easy to unlock the combination of the first fixing member 12 and the second fixing member, thereby performing disassembly between the barcode scanner body 1 and the mounting portion 3.

[0029] In another embodiment, the first fixing member 12 may also be disposed on the side 13 of the barcode scanner body 1 , and the second fixing member is correspondingly disposed on the side 31 of the mounting portion 3 , and the first fixing member 12 protrudes from the side 32 of the mounting portion 3 .

[0030] In addition, please continue to see Figure 5 and Figure 6 The cantilever structure 5 also includes a cantilever beam 6, and the cantilever beam arm 6 is used to realize the return of the trigger button 51, the cantilever beam arm connecting rod 52 and the magnet fixing rod 54. Specifically, the cantilever beam 6 is an elastic element, one end of the cantilever beam 6 is fixedly connected to the cantilever beam connecting rod 52, and the other end of the cantilever beam 6 abuts against the inside of the grip 4. In actual use, according to actual conditions, the trigger button 51 may be pressed, the trigger button 51 pushes the cantilever beam connecting rod 52 to move, and the cantilever beam connecting rod squeezes the cantilever beam 6 (elastic element), so that the elastic element is in a compressed state. When the force applied to the trigger button 51 is released, the elastic element will recover from the compressed state to the natural state, thereby driving the trigger button 51, the cantilever beam connecting rod 52 and the magnet fixing rod 54 to realize the return. Alternatively, the trigger button 51 is pressed, and the trigger button 51 pushes the cantilever beam connecting rod 52 to move, and the cantilever beam connecting rod 52 stretches the cantilever beam 6 (elastic element), so that the elastic element is in a stretched state. When the force applied to the trigger button 51 is released, the elastic element will recover from the stretched state to the natural state, thereby driving the trigger button 51, the cantilever arm connecting rod 52 and the magnet fixing rod 54 to return to their original position.

[0031] In addition, the handle portion 4 is further provided with a pressing portion 34, which is located above the magnet connecting rod 54 and abuts against the magnet connecting rod 54 to ensure that the magnet 53 on the magnet fixing rod 54 moves stably toward the Hall sensor 11. Preferably, the pressing portion 34 may be formed by providing a pressing block 35 on a beam, the pressing block 35 abuts against the magnet fixing rod 54, and when the magnet fixing rod 54 moves in the first direction F1 driven by the cantilever beam connecting rod 52, the pressing block 35 can slide relatively on the magnet fixing rod 54, thereby ensuring that the magnet 53 on the magnet fixing rod 54 moves stably toward the Hall sensor 11.

[0032] Moreover, preferably, in order to ensure comfort when using the code scanning device, the shape design of the handle structure is consistent with the shape of a human hand holding it.

[0033] As mentioned above, the specific implementation of the present invention is specifically: (1) Install (sleeve) the scanner body directly on the mounting part of the handle structure; (2) Pressing the trigger button drives the cantilever beam connecting rod to rotate along the rotating shaft on the cantilever beam connecting rod. The rotation of the cantilever beam connecting rod drives the magnet fixing part to translate. The magnet fixing rod is equipped with a magnet. The magnet approaches the Hall sensor and triggers the Hall sensor. (3) Release the trigger button. Under the elastic force of the cantilever beam, the trigger button, cantilever beam connecting rod and magnet fixing rod return to their original positions, so that the magnet moves away from the Hall sensor, thereby disconnecting the Hall sensor.

[0034] Moreover, the handle structure of the present invention is suitable for installing various code scanning PDA products.

[0035] In summary, the present invention combines the scanner body with the handle in a detachable connection, which is flexible to assemble and disassemble. In addition, the handle structure is designed with an internal structure and equipped with a magnet, and the Hall sensor on the scanner body is activated by the magnet in the handle structure to realize the operation of the scanner. In other words, when the user actually operates, a long-term operation can be easily achieved by operating only one trigger button.

In addition, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other. It must be pointed out that the disclosed embodiments do not limit the scope of the present invention. On the contrary, changes and modifications made without departing from the spirit and scope of the present invention are all within the scope of patent protection of the present invention.
