Description

Technical Field

[0001] The utility model relates to the technical field of large-scale equipment with tracks, and more specifically, the utility model relates to a bar code positioning device. Background Art

[0002] Existing barcode positioning equipment generally includes a reader and a code strip, in which the reader is fixed on a mobile device and is used for navigation and control needs of the vehicle. The reader has a built-in industrial camera and lighting unit, which can scan and process specified colors and QR codes. The position data is printed on the position code strip in the form of a Data Matrix QR code. Each Data Matrix contains unique position data. The industrial camera in the reader captures the QR code on the code strip through visual imaging, thereby outputting the position data, obtaining the moving position of the large equipment, and then transmitting the position to the PLC control system for closed-loop control to achieve unmanned control.

[0003] After searching, the Chinese patent with announcement number CN217477781U discloses a positioning device for the fitting position of a tire barcode label. The position adjustment block moves along the slide groove to fit with the tire mouth, and the butterfly nut is tightened to fix the position adjustment block. The fitting position of the barcode label is determined by a measuring ruler. The device has a simple structure, is easy to operate, has accurate positioning, and is highly efficient, ensuring that the barcode label is fitted to the specified position.

[0004] When the above positioning device is in use, the screw is perpendicular to the length direction of the measuring rod and is detachably connected to the position adjustment block, so that the surveyor can ensure accurate readings. However, manual reading is required, which is prone to certain errors. At the same time, the labor intensity of the surveyor is high. When measuring through the barcode positioning equipment, when the dock is subjected to external forces (such as collision, extrusion, pulling, etc.), the equipment structure is deformed, and it is inconvenient to adjust the position of the barcode positioning equipment, thereby affecting the positioning accuracy of large equipment. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a barcode positioning device, aiming to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bar code positioning device, comprising a reader, which is equipped with a PLC control system, three joints are fixedly installed on one side of the reader, a mounting frame is movably provided at the bottom of the reader, a connecting plate is movably provided between the mounting frame and the reader, an adjustment component is provided on the connecting plate, and the adjustment component includes a screw rod and a slider, the top and bottom ends of the screw rod are movably connected to the mounting frame through bearings, the slider is movably sleeved on the screw rod, and the rear side of the slider is fixedly connected to the connecting plate.

[0007] Furthermore, a handle is movably provided on the top of the sliding block, and the handle is fixedly sleeved on the screw rod.

[0008] It can be seen that in the above technical solution, it is convenient to drive the screw rod to rotate.

[0009] Furthermore, two limiting plates are fixedly connected to the front side of the connecting plate, and the front sides of the two limiting plates extend into the mounting frame.

[0010] Furthermore, side plates are fixedly connected to both sides of the reader, and a fixing component is provided between the two side plates, and the fixing component includes two springs, two sliding sleeves, two sliding cylinders, two vertical plates, two plug blocks and two cross bars.

[0011] Furthermore, one ends of the two springs and the two cross bars are fixedly connected to the connecting plate, the other ends of the two springs are fixedly connected to the two sliding sleeves, and the other ends of the two cross bars pass through the two sliding cylinders, respectively. The opposite sides of the two sliding sleeves are fixedly connected to the two sliding cylinders, respectively. The opposite ends of the two sliding cylinders and the two plug blocks are fixedly connected to the two vertical plates, respectively, and the two plug blocks are located in the two side plates, respectively.

[0012] Furthermore, the bottom ends of the two sliding sleeves are fixedly connected to side plates, and the bottom ends of the two side plates extend into the connecting plate.

[0013] It can be seen that in the above technical solution, the two side plates can prevent the two sliding sleeves from deflecting when moving horizontally.

[0014] Furthermore, the mounting frame is provided with a plurality of jacks.

[0015] It can be seen that in the above technical solution, the bolts are inserted into the insert block, and the mounting frame is fixed by the bolts.

[0016] Technical effects and advantages of the utility model:

[0017] 1. The utility model drives the screw to rotate by rotating the handle. Since the slider is threadedly connected to the screw, the two limit plates and the mounting bracket cooperate to limit the rotation of the slider, so the screw can drive the slider to move upward, thereby driving the connecting plate to move upward, and then driving the reader to move upward. The position of the reader is adjusted according to demand, so that the reader and the barcode on the code tape are on the same horizontal line, and alignment adjustment is achieved, which solves the problem of low accuracy after long-term use. The operation is simple, and the parameters are not prone to errors, which effectively reduces the labor intensity of the user and effectively improves the accuracy of large equipment with tracks in movement;

[0018] 2. The utility model drives the two springs to stretch by moving the two sliding sleeves away from each other. At the same time, the two sliding sleeves can drive the two sliding cylinders to move away from each other, and then drive the two vertical plates to move away from each other. Then the reader is placed on the connecting plate, the two sliding sleeves are loosened, and the two springs rebound and drive the two sliding sleeves to move toward each other, so that the two plug-ins move toward each other into the two side plates, and then the connecting plate and the reader are fixed. Similarly, the reader can be disassembled and repaired. The structure is simple and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
