Description

Technical Field

[0001] The utility model relates to a movable barcode reader, belonging to the field of barcode readers. Background Art

[0002] With the continuous development of science and technology, barcode technology has been widely used in various fields such as retail, logistics, and manufacturing, becoming an important means of data collection and exchange.

However, some barcode readers have some obvious deficiencies in use, especially in terms of mobility and height adjustment. These deficiencies limit the application of barcode readers in complex scenarios. Most general barcode readers require handheld operation, which to a certain extent limits their scope of use. In large warehouses, production lines and other scenarios where long-term and large-scale barcode scanning is required, handheld operation not only increases the labor intensity of operators, but also easily leads to reduced scanning accuracy due to fatigue. In addition, these barcode readers often cannot be easily adjusted in height, so that when scanning barcodes at different heights, operators need to frequently adjust their posture or use external tools for assistance, thereby reducing work efficiency.

[0026] It should be noted that the two supports 2 are respectively fixedly connected to the left side and the right side of the inner bottom wall of the bracket 1 , and the upper surface of the support 2 is provided with a receiving opening adapted to the electric push rod 3 .

[0027] The left slider 5 is fixedly connected to the left side wall of the left connecting block 4, the upper and lower ends of the left slide bar 6 are bent to the left and fixedly connected to the inner left side wall of the bracket 1, the right slider 5 is fixedly connected to the right side wall of the right connecting block 4, the upper and lower ends of the right slide bar 6 are bent to the right and fixedly connected to the inner right side wall of the bracket 1.

[0028] One end of the back side of the transmission threaded rod 9 sequentially penetrates the front side of the frame 7, the center of the transmission wheel 10 and the thread groove of the corresponding threaded block 14 and is rotatably connected to the inner rear side wall of the frame 7; one end of the front side of the driven threaded rod 13 is rotatably connected to the inner front side wall of the frame 7; and one end of the back side of the driven threaded rod 13 sequentially penetrates the center of the driven wheel 12 and the thread groove of the corresponding threaded block 14 and is rotatably connected to the inner rear side wall of the frame 7.

[0032] The working principle of the above embodiment is:

[0033] When adjusting the height, the electric push rod 3 is started. When the movable rod of the electric push rod 3 is extended or retracted, the connecting block 4 and the front and rear adjustment components connected thereto are driven to move in the vertical direction. When the front and rear adjustment components move, the barcode reader body 22 is driven to move in the vertical direction, thereby adjusting the height of the barcode reader body 22.

[0034] When the barcode reader body 22 needs to move forward or backward, the servo motor 8 is started. When the servo motor 8 is started, the transmission threaded rod 9 is driven to rotate, and the transmission threaded rod 9 then drives the transmission wheel 10 to rotate. The transmission wheel 10 then drives the driven wheel 12 to rotate through the transmission belt 11. The driven wheel 12 drives the driven threaded rod 13 to rotate synchronously during the rotation. The outer sides of the transmission threaded rod 9 and the driven threaded rod 13 are both threadedly connected with thread blocks 14. When the transmission threaded rod 9 and the driven threaded rod 13 rotate, the two will respectively drive the corresponding thread blocks 14 to move. When the thread block 14 moves, it will drive the guide block 16 to move. The guide block 16 then drives the mounting block 18 to move. The mounting block 18 then drives the mounting frame 19 and the barcode reader body 22 inside the mounting frame 19 to move forward and backward.

[0035] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.
