Description

Technical Field

[0001] The utility model relates to the technical field of label scanning, and particularly relates to an RFID label positioning and scanning device. Background Technique

[0002] RFID label scanning mainly refers to the process of identifying RFID labels on the surfaces of various items through radio frequency scanning. At the same time, compared with traditional barcode recognition technology, RFID technology has better waterproof and anti-magnetic effects.

[0003] In the prior art, people often need to use a special scanning device to scan and pre-check RFID labels after their production and processing are completed.

[0004] However, in the actual scanning and pre-checking process, due to the fact that traditional conveying devices often generate a certain degree of vibration during operation, the RFID labels placed on the surface of the conveying device will also generate a certain degree of vibration accordingly. As a result, the scanning device cannot fully scan and identify them, thus affecting the pre-checking process. At the same time, during the pre-checking process, due to the different positions of different RFID labels, people often need to adjust the position of the scanning device. However, most traditional adjustment methods need to be achieved by repeatedly rotating bolts, so the adjustment process is relatively cumbersome. In view of this, we propose an RFID label positioning and scanning device. Content of the Utility Model

[0005] The main purpose of the utility model is to provide an RFID label positioning and scanning device, which solves the problems mentioned in the above background technique.

[0006] To achieve the above purposes, an RFID label positioning and scanning device proposed by the utility model includes a conveyor belt. Baffles are rotatably connected to both sides of the conveyor belt. An adjustable positioning device is arranged on the upper surface of the baffle, and an alignment device is arranged inside the baffle.

[0007] The adjustable positioning device includes a support plate. A sliding rod is fixedly connected to the center of the inner surface of the support plate. A slider is slidably connected to the outer surface of the sliding rod. A scanner is fixedly connected to the lower surface of the slider. A limiting rod is slidably connected to the inner surface of the slider, and a limiting block is fixedly connected to the outer surface of the limiting rod.

[0008] Preferably, the alignment device includes a button. An inner rod is fixedly connected to the lower surface of the button. The outer surface of the inner rod is slidably connected to an outer rod, and a spring piece is fixedly connected to the outer surface of the outer rod.

[0009] Preferably, two sets of conveying rollers are arranged inside the conveyor belt, and a through hole is formed in the center of the inner surface of the support plate.

[0010] Preferably, a plurality of arc-shaped grooves are formed on the upper surface of the sliding rod, and there are two support plates, and the two support plates are symmetrically distributed with the midline of the conveyor belt as the axis of symmetry.

[0011] Preferably, a through hole is formed at the center of the inner surface of the slider, and a through groove is formed at the upper end of the slider.

[0012] Preferably, a through hole is formed at the center of the inner surface of the limiting block, the upper surface of the limiting block is elastically connected to the slider through a spring, and the outer surface of the limiting block is slidably connected to the slider.

[0013] Preferably, a rectangular groove is formed at the position of the baffle plate close to the outer rod, a through hole is formed on the upper surface of the baffle plate, a plurality of arc-shaped grooves distributed in a circumferential array are formed on the upper surface of the baffle plate, and a cylindrical protrusion is arranged on the lower surface of the button.

[0014] Preferably, rectangular protrusions are arranged on both sides of the inner rod, a groove with the same cross-sectional shape as the inner rod is formed on the upper surface of the outer rod, the lower end of the inner rod is elastically connected to the outer rod through a spring, and the elastic sheet is arc-shaped.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] (1) When the RFID tag positioning and scanning device is in use, it is necessary to lift the limiting rod upward according to the actual shape and size of the RFID tag. At this time, the limiting rod will move away from the groove on the upper surface of the sliding rod, so that people can arbitrarily push the slider to slide on the outer surface of the sliding rod. When the slider slides, the scanner will also be driven by the slider to move, so that the actual scanning position of the device is adjustable. At the same time, after the adjustment is completed, it is necessary to loosen the limiting rod so that the spring can push the limiting block and the limiting rod downward to the groove on the upper surface of the sliding rod due to its own elastic force. At this time, the rapid positioning of the slider can be completed, and the overall operation process is relatively simple compared with repeatedly screwing the bolts.

[0017] (2) When the RFID tag positioning and scanning device is in use, it is necessary to place the RFID tag waiting for conveyor pre-inspection on the upper surface of the conveyor belt. At this time, the conveyor belt can be started to convey it to the scanner. At the same time, during the conveying process, the elastic sheets on both sides will gradually contact the RFID tag and can push it toward the center of the conveyor belt due to their own elastic force. At the same time, when conveying RFID tags of different sizes, the button can be lifted and rotated, so that the inner rod and the outer rod rotate simultaneously. At this time, the outer rod will drive the elastic sheet to change the angle, so as to realize the adjustment of the initial angle of the elastic sheet. BRIEF DESCRIPTION OF THE DRAWINGS

When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0027] Please refer to Figures 1-4 , the present utility model provides a technical solution: an RFID tag positioning and scanning device, including a conveyor belt 1, baffles 4 rotatably connected to both sides of the conveyor belt 1, an adjustable positioning device 2 arranged on the upper surface of the baffles 4, and an alignment device 3 arranged inside the baffles 4;

[0028] The adjustable positioning device 2 includes a support plate 201, a slide bar 202 fixedly connected to the center of the inner surface of the support plate 201, a slider 203 slidably connected to the outer surface of the slide bar 202, a scanner 205 fixedly connected to the lower surface of the slider 203, a limiting rod 204 slidably connected to the inner surface of the slider 203, and a limiting block 206 fixedly connected to the outer surface of the limiting rod 204.

[0029] Specifically, two sets of conveyor rollers are arranged inside the conveyor belt 1, so that it can drive the conveyor belt 1 to rotate under the drive of an external motor. A through hole is opened at the center of the inner surface of the support plate 201, so that the slide bar 202 can be installed inside it. A plurality of arc-shaped grooves are opened on the upper surface of the slide bar 202, so that when the limiting rod 204 is inserted into the groove, the position of the slider 203 can be limited. Two sets of support plates 201 are provided, and the two sets of support plates 201 are symmetrically distributed with the midline of the conveyor belt 1 as the axis of symmetry. A through hole is opened at the center of the inner surface of the slider 203, so that it can slide on the outer surface of the slide bar 202. A through groove is opened at the upper end of the slider 203, so that the limiting rod 204 and the limiting block 206 can be accommodated to slide inside it. A through hole is opened at the center of the inner surface of the limiting block 206, and the upper surface of the limiting block 206 is elastically connected to the slider 203 through a spring. Therefore, when people release the limiting rod 204, the spring can push the limiting block 206 and the limiting rod 204 downward through its own elastic force, and the outer surface of the limiting block 206 is slidably connected to the slider 203.

[0030] In the embodiment of the present utility model, the alignment device 3 includes a button 301, an inner rod 302 fixedly connected to the lower surface of the button 301, the outer surface of the inner rod 302 is slidably connected to an outer rod 303, and a elastic piece 304 is fixedly connected to the outer surface of the outer rod 303.

[0031] Specifically, a rectangular groove is provided near the baffle 4 close to the outer rod 303, so that the elastic piece 304 can be accommodated to generate an angular offset inside it. A through hole is provided on the upper surface of the baffle 4, so that the inner rod 302 can be accommodated to rotate inside it. A plurality of arc-shaped grooves distributed in a circumferential array are provided on the upper surface of the baffle 4, so that when the protrusion on the lower surface of the button 301 is inserted into the groove, the angle of the button 301 can be limited. A cylindrical protrusion is provided on the lower surface of the button 301, and rectangular protrusions are provided on both sides of the inner rod 302, so that it can drive the outer rod 303 to rotate simultaneously during the rotation process. A groove having the same cross-sectional shape as the inner rod 302 is provided on the upper surface of the outer rod 303. The lower end of the inner rod 302 is elastically connected to the outer rod 303 through a spring. Therefore, when people release the inner rod 302, the spring can pull the inner rod 302 to move into the outer rod 303 due to its own elastic force. The elastic piece 304 is arranged in an arc shape.

[0032] During operation (or use), the RFID tags waiting for pre-conveyor inspection need to be placed on the upper surface of the conveyor belt 1. At this time, the conveyor belt 1 can be started to convey it to the scanner 205. At the same time, during its conveying process, the elastic pieces 304 on both sides will gradually contact the RFID tags and can push them towards the center of the conveyor belt 1 due to their own elastic force. At the same time, when conveying RFID tags of different sizes, the button 301 can be lifted upward and rotated, so that the inner rod 302 and the outer rod 303 rotate simultaneously. At this time, the outer rod 303 will drive the elastic piece 304 to generate an angular change, thereby realizing the adjustment of the initial angle of the elastic piece 304.

[0033] At the same time, before using this device, the limit rod 204 needs to be lifted upward according to the actual shape and size of the RFID tag. At this time, the limit rod 204 will move away from the groove on the upper surface of the slide rod 202, so that people can arbitrarily push the slider 203 to slide on the outer surface of the slide rod 202. When the slider 203 slides, the scanner 205 will also be driven by the slider 203 to move, so that the actual scanning position of this device can be adjusted. At the same time, after the adjustment is completed, the limit rod 204 needs to be released so that the spring can push the limit block 206 and the limit rod 204 downward to move into the groove on the upper surface of the slide rod 202. At this time, the rapid limit of the slider 203 can be completed, and the overall operation process is relatively simple compared to repeatedly screwing bolts.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
