Description
Technical Field
[0001] This invention relates to the field of logistics and transportation technology, specifically to a device for rapid barcode indication. Background Technology
[0002] A barcode scanner is a machine that reads barcode information. It uses an infrared light source to emit light, and then a chip decodes the reflected light to return the correct characters represented by the barcode. Barcode scanners are often used in cargo logistics to identify and track goods. However, since barcodes are usually affixed to the packaging, staff must search for the barcode on the packaging, which is time-consuming and prone to missed scans.
[0003] Existing technology, utility model patent CN215341091U, discloses an intelligent barcode scanning device based on barcode recognition technology, including a chassis. A control computer is installed at the bottom of the chassis's inner cavity. A support plate is welded to the inner wall of the chassis, and a power supply is installed on the top of the support plate. A cardboard box is welded inside the chassis. A camera is fixedly installed on the top of the chassis's inner cavity with screws, and a microcontroller control board is fixedly connected to the inner wall of the chassis with screws. The device uses the camera and microcontroller to scan and recognize barcodes, and transmits data to an LCD screen to provide feedback on the presence and correctness of barcodes for operator identification. Automatic scanning and recognition of information from a display panel, automatic data transmission, and automatic collection of information from the display panel improve work efficiency. However, this existing technology can only recognize barcodes pasted on one side of the packaging box, especially when the barcode is pasted facing downwards, in which case it cannot be recognized.

[0030] The working principle of the device for rapid barcode indication disclosed in this invention is as follows: First, the goods that need to be indicated by scanning the barcode are placed on the transparent plate 101 (with the barcode affixed). Then, the electromagnet 102 is activated, and the electromagnet 102 generates magnetic force to attract the iron plate 103 downward. At this time, the leaf spring 104 will be subjected to downward pressure and then swing along the connection point with the electromagnet 102. When the electromagnet 102 loses its magnetic force, the iron plate 103 will return to its original position under the elastic force of the leaf spring 104. The movement trajectory is also an arc shape. At this time, the goods on the transparent plate 101 will make the same movement (an upward parabola). Therefore, the goods move intermittently on the transparent plate 101 (the intermittent frequency is the same as the energizing and de-energizing frequency of the electromagnet 102). When the goods move to the center of the transparent plate 101 (the position where there is no obstruction below), the goods will move in an arc. Before this, the drive motor 201 needs to be continuously running. The output shaft of the drive motor 201 will drive the pulley 203 to rotate. The rotation of the pulley 203 will drive the toothed drive belt 202 to rotate. The rotation of the toothed drive belt 202 will intermittently drive the input gear 212 to rotate (the toothed drive belt 202 has incomplete tooth profiles). When the input gear 212 rotates, it will drive the winding reel 213 to rotate, the input shaft of the reducer 204 to rotate, and the winding reel 213 on another longitudinal sliding plate 208 to rotate via the lead screw 224. Figure 12As shown, the rotation of the reel 213 winds the belt 214 onto it, simultaneously pulling the pull block 232 upwards (and the scanning head support plate 222 and scanning head 3 also move accordingly). Due to the meshing relationship between the vertical rotating gear 234 and the vertical rack 230, the scanning head 3 rotates while moving, allowing it to scan barcodes at different pasting angles and heights. When the input gear 212 disengages from the toothed drive belt 202, the belt 214 wound on the reel 213 is unwound under the tension of the tension spring 231. Through the continuous engagement and disengagement of the input gear 212 with the toothed drive belt 202, the vertical movement and rotation of the scanning head 3 on the longitudinal sliding plate 208 are achieved. Simultaneously, the rotation of the lead screw 224 is also reciprocating, so the scanning head 3 on the nut block 225 also moves linearly back and forth, while simultaneously engaging with the rotating rack 223 and the rotating gear plate 227, thus also rotating. Because of the presence of the reducer 204, the reversal of the winding reel 213 is subject to resistance, and therefore proceeds slowly. The output shaft of the reducer 204 drives the air pump 205, which compresses air into the sealed housing 210. The gearbox 217 in the sealed housing 210 then moves as a piston under pressure, while excess air is discharged through the exhaust port 218. This discharged air drives the impeller 216 to rotate, which in turn drives the rotating shaft 229 to rotate via the gearbox 217. At this point, the scanning head 3, mounted on the three transverse sliding plates 207, rotates. Simultaneously, the piston movement of the gearbox 217 causes the scanning head 3 to rotate. When the toothed drive belt 202 and the input gear 212 disengage, the air pump 205 loses power (because the reducer 204 exists, the air pump 205 needs a high speed, and at this time the air pump 205 is in reverse, so it will no longer pressurize the sealed shell 210), while the gearbox 217 will be reset under the action of the spring 219, squeezing out the air in the sealed shell 210 and expelling it through the exhaust port 218, while driving the impeller 216 to rotate. Repeating this process can realize the reciprocating motion and rotation of the scanning head 3 on the transverse sliding plate 207.
