Description

[0002] A QR code is a graphic identifier that is arranged according to certain coding rules to express a group of information. It is mainly used for product tracking, production control, and automatic identification. A barcode reader is a reading device used to read the information contained in a barcode. It uses optical principles to decode the content of a one-dimensional or two-dimensional barcode and transmits it to a computer or other processing equipment via a data cable or wireless communication. It is currently widely used in various commercial checkout, express logistics, warehousing and transportation, and intelligent manufacturing fields, becoming an important part of the Internet of Things ecosystem.

[0045] The working principle and use process of the present invention:

[0046] Step 1, fix the device on one side of the production line by fixing the base 1, start the first servo motor 22 to drive the screw rod 23 to rotate clockwise, the clockwise rotation of the screw rod 23 drives the threaded block 24 to move upward, the threaded block 24 drives the limit block 27 to move upward synchronously through the fixed rod 26, the movement of the limit block 27 is rotated by the cooperation of the rolling ball 29, the contact friction with the installation groove 21 is reduced, and the threaded block 24 is stably moved by the cooperation of the limit block 27, the movement of the threaded block 24 and the limit block 27 drives the support plate 211 to move upward through the first support block 25 and the second support block 210, and the upward movement of the support plate 211 drives the positioning block 3 to move upward through the cooperation of the third support block 212;

[0047] Step 2, when the height adjustment is completed, the piston rod of the small servo electric cylinder 314 is started to retract, and the support 313 is driven to move through the connecting block 315. The movement of the support 313 drives the limiting sleeve 311 to move, so that the connecting plug 312 on one of the limiting sleeves 311 is separated from the guide plug 35. At this time, the second servo motor 316 is started to drive the worm 317 to rotate clockwise. The rotation of the worm 317 drives the rotating rod 38 to rotate through the meshing worm wheel 310. The rotation of the rotating rod 38 is stabilized by the mounting seat 37. The rotation of the rotating rod 38 drives the two limiting sleeves 311 to rotate through the cooperation of the limiting strip 39, and the rotation of the other limiting sleeve 311 drives one of the driving sleeves 34 to rotate through the cooperation of the connecting plug block 312 and the guide plug block 35, and the rotation of one of the driving sleeves 34 drives the driving gear 36 to rotate, and the rotation of the driving gear 36 drives the installation box 33 to move through the meshing moving rack 32, and the movement of the installation box 33 drives the driving block 4 to move synchronously through the cooperation of the other driving sleeve 34;

[0048] Step 3: After the lateral adjustment is completed, the piston rod of the small servo electric cylinder 314 extends, so that it drives the support 313 to move in the opposite direction through the connecting block 315. At this time, the limiting sleeve 311 moves in the opposite direction, so that the connecting plug 312 on the other limiting sleeve 311 is separated from the guide plug 35, and the second servo motor 316 is started again to drive the worm 317 to rotate clockwise. The rotation of the worm 317 drives the rotating rod 38 to rotate through the meshing worm wheel 310, and the rotation of the rotating rod 38 brings The two limiting sleeves 311 are driven to rotate, and the rotation of one limiting sleeve 311 drives the other driving sleeve 34 to rotate through the cooperation of the connecting plug block 312 and the guide plug block 35, and the rotation of the other driving sleeve 34 drives the code reader body 414 to perform clockwise angle fine adjustment through the cooperation of the driving block 4, and vice versa, when the worm 317 rotates counterclockwise, it drives the code reader body 414 to perform counterclockwise angle fine adjustment, and the self-locking characteristics of the worm wheel 310 and the worm 317 improve the stability after adjustment;

[0049] Step 4: After the rotation adjustment is completed, the first drive motor 46 is started to drive the first transmission shaft 47 to rotate clockwise. The rotation of the first transmission shaft 47 drives the second gear 48 to rotate. The rotation of the second gear 48 drives the meshed first gear 44 to rotate. The rotation of the first gear 44 drives the arc block 45 to adjust the upper elevation angle through the driving rod 43, thereby driving the code reader body 414 to adjust the upper elevation angle. Conversely, when the first transmission shaft 47 is rotated counterclockwise, the code reader body 414 is driven to adjust the lower elevation angle.

[0050] Step five, after the elevation angle is adjusted, the second drive motor 416 can be started in real time according to the usage requirements. The second drive motor 416 drives the third gear 418 to rotate clockwise and counterclockwise through the second transmission shaft 417. When rotating clockwise, the movable seat 411 is driven to move through the meshing arc gear ring 412, thereby driving the code reader body 414 to perform arc movement adjustment, thereby changing the scanning angle. Conversely, when the third gear 418 is rotated counterclockwise, it drives the code reader body 414 to perform reverse arc movement adjustment.
