To facilitate an understanding of the invention, the invention will now be described more fully hereinafter with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "inner", "outer", "left", "right" and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

An embodiment of a scanning device may be used to check material storage.

As shown in fig. 1, the scanning device 10 includes a mount 100, a rotating assembly 200, a swinging assembly 300, and an RFID reader 400. Among other things, the mounting base 100 can serve as a base of the scanning apparatus 10 to mount the scanning apparatus 10 to a building such as a wall, a ceiling, or the like. The rotating assembly 200 and the swinging assembly 300 are respectively used for driving the RFID reader 400 to rotate within a two-dimensional space range, so that the RFID reader 400 scans a space to be scanned. When the space to be scanned is a cylindrical space, the scanning device 10 can be installed in the middle of the cylindrical space by using the installation base 100, so as to meet the requirement of omni-directional scanning. In other embodiments, the scanning device 10 may also be mounted to a suitable position where scanning is required by using the mounting base 100 according to actual needs, which is not described herein.

Referring to fig. 2 and 3, the mounting base 100 has a first axis w1, the rotating assembly 200 includes a base 210 and a driving element 220, the base 210 is rotatably mounted on the mounting base 100, and the driving element 220 is disposed on the base 210 and is used for driving the base 210 to rotate around the first axis w1 relative to the mounting base 100.

The swing assembly 300 includes a driving gear 310, a transmission gear 320 and a swing arm 330, the swing arm 330 is rotatably connected to the base 210 and has a second axis w2, the transmission gear 320 is fixed on the swing arm 330, the driving gear 310 is mounted on the base 210 and is engaged with the transmission gear 320, and the driving gear 310 is used for driving the swing arm 330 to rotate around a second axis w2w2 relative to the base 210.

The RFID reader 400 is mounted on the swing arm 330 to face different directions by being driven by the swing arm 330.

In this embodiment, because the base 210 can rotate around the first axis w1 relative to the mounting base 100 under the driving of the driving element 220, the driving gear 310 can rotate around the second axis w2 relative to the base 210 by engaging the driving swing arm 330 through the driving gear 320, so that the swing arm 330 can drive the RFID reader-writer 400 to rotate around the first axis w1 relative to the mounting base 100 and simultaneously rotate around the second axis w2, so that the RFID reader-writer 400 can realize multi-angle reading and writing in different directions. The structure form of the meshing transmission is simple, and the assembly is convenient; meanwhile, the movement is stable, so that the space scanning posture of the RFID reader-writer 400 can be stably changed, the scanning effectiveness is ensured, and poor scanning reading-writing effect caused by the occurrence of a scanning blind area is avoided.

It should be noted that the first axis w1 and the second axis w2 form a certain included angle, that is, the first axis w1 and the second axis w2 are not parallel and collinear, and then the swing arm 330 rotates around the second axis w2 relative to the base 210 and rotates around the first axis w1 relative to the mount base 100 relative to the base 210, so that the orientation of the RFID reader-writer 400 can be arbitrarily adjusted in two dimensions, and the scanning range is increased. For example, in some embodiments, the first axis w1 and the second axis w2 are perpendicular to each other, so that the scanning range of the RFID reader-writer 400 is sufficiently large by combining the rotation of the base 210 around the first axis w1 and the rotation of the swing arm 330 relative to the base 210 around the second axis w2, that is, when the belt scanning space is constant, fewer RFID readers-writers 400 can be arranged in this way, thereby saving the cost.

In some embodiments, the holder body 210 is rotatably connected to the mounting seat 100 through a rotating shaft 230. The shaft 230 includes opposite first and second ends 231 and 232. The first end 231 is connected to the mounting base 100 along the first axis w1, that is, the longitudinal axis of the rotating shaft 230 coincides with the first axis w 1. In this embodiment, the second end 232 is connected to the housing 210. So that the rotational connection between the holder body 210 and the mounting seat 100 is realized by the rotation shaft 230.

It should be noted that the rotational connection between the base 210 and the mounting base 100 through the rotation shaft 230 can be in various forms. For example, in some embodiments, the mounting base 100 is provided with the connecting portion 120, the first end 231 of the rotating shaft 230 is fixedly connected to the connecting portion 120, and the second end 232 is rotatably connected to the base 210, so that the base 210 can rotate around the rotating shaft 230, and since the rotating shaft 230 is connected to the mounting base 100 along the first axis w1, the base 210 can rotate around the first axis w1 relative to the mounting base 100.

In another embodiment, the first end 231 of the rotating shaft 230 is rotatably connected to the connecting portion 120, and at this time, no matter whether the second end 232 of the rotating shaft 230 is rotatably connected or fixedly connected with the base 210, the relative movement between the base 210 and the mounting base 100 can be realized by the rotation between the rotating shaft 230 and the mounting base 100, so that the RFID reader 400 can rotate around the rotating shaft 230 along with the swing arm 330.

The connecting portion 120 may be formed with an opening to fit the shaft 230, for example, as shown in fig. 3, the connecting portion 120 has a shaft hole 121, and the first end 231 of the shaft 230 fits the shaft hole 121 along the first axis w1 to connect the shaft 200 to the mounting base 100.

In some embodiments, the mounting base 100 has a mounting portion 110, and the mounting base 100 can be mounted and fixed to a ceiling or the like by the mounting portion 110. In some embodiments, the driving member 220 drives the seat body 210 to rotate about the first axis w1 relative to the mounting seat 100 by means of meshing transmission.

The mounting base 100 is provided with an engaging portion 130, the driving member 220 includes a power source 221 and a transmission portion 222, the transmission portion 222 is engaged with the engaging portion 130, the power source 221 is disposed in the base 210 and is configured to drive the transmission portion 222 to move, so that the base 210 rotates relative to the mounting base 100. The power source 221 can be a motor or a link mechanism, as long as it is ensured that the transmission portion 222 can engage the transmission engagement portion 130 under the driving of the power source 221, so as to rotate the seat body 210 relative to the mounting seat 100. Through this kind of mode of setting, when pedestal 210 rotated relatively mount 100, just can drive RFID reader-writer 400 and rotate together, and then change the orientation of RFID reader-writer 400 in this dimension around first axis w1, realize multi-angle scanning.

As shown in fig. 2 and fig. 3, the engaging portion 130 includes a gear ring 131, and the center of the gear ring 131 is located on the first axis w1, so that when the transmission portion 222 engages the transmission engaging portion 130, the base 210 can rotate 360 ° around the first axis w1 relative to the mounting base 100, and the RFID reader 400 connected to the base 210 via the swing arm 330 can also rotate 360 ° adaptively, so as to implement omnidirectional scanning by matching the rotation of the swing arm 330.

One side of the mounting base 100 facing away from the mounting portion 110 is provided with a groove 101, the engaging portion 130 is disposed at the groove 101, and a part of the structure of the transmission portion 222 protrudes from the base 210 and is received in the groove 101.

In this embodiment, the groove 101 can fully utilize the installation space of the mounting base 100, so that the assembly between the base 210 and the mounting base 100 is more compact without a large gap affecting the overall structure of the scanning device 10.

In addition, since the transmission part 222 is protruded out of the base body 210 and is accommodated in the groove 101 to be engaged with the engaging part 130 located in the groove 101, the engaging structure of the transmission part 222 and the engaging part 130 is not exposed, so that the appearance is attractive, and meanwhile, the external object can be prevented from easily entering the engaging part of the transmission part 222 and the engaging part 130 to interfere with the engaging transmission effect of the transmission part 222 and the engaging part 130. This arrangement can improve the rotational stability of the base 210 with respect to the mounting base 100, and further enable the RFID reader 400 to perform scanning motion stably.

In other embodiments, the engaging portion 130 includes a circular-arc-shaped toothed disc, and the center of the circular-arc-shaped toothed disc is located on the longitudinal axis of the rotating shaft 230, in this way, the base 210 can also rotate relative to the mounting base 100 by the engagement transmission of the transmission portion 222 and the toothed disc. The fluted disc structure is arranged in a flat shape, so that the assembly gap between the base body 210 and the mounting base 100 can be reduced under the condition that the groove 101 is not arranged. Of course, in some embodiments, the toothed disc can also be disposed in the groove 101 of the mounting base 100, so that the fitting between the base body 210 and the mounting base 100 is tighter.

It should be noted that the transmission portion 222 is used as a mating member engaged with the engaging portion 130 to drive the seat body 210 to rotate relative to the mounting base 100, and the transmission portion 222 has teeth matched with the engaging portion 130 no matter whether the engaging portion 130 is a toothed ring 131 or a toothed disc. For example, in some embodiments, the transmission portion 222 may be a gear capable of engaging with the engaging portion 130, and the gear is disposed on a rotating member capable of rotating relative to the seat 210, so that as the rotating member rotates relative to the seat 210, the engagement between the gear and the engaging portion 130 causes the seat 210 to rotate relative to the mounting base 100 around the rotating shaft 230. When the power source 221 is a motor, the rotating member may be an output shaft of the motor, that is, the output shaft of the motor penetrates through the seat body 210 and is connected to the gear, so that when the output shaft of the motor rotates, the gear engages with the transmission engaging portion 130 to rotate the seat body 210 relative to the mounting seat 100. In other embodiments, when the power source 221 employs a link mechanism, the rotating member may be a pin rotatably connected to the seat 210, and a gear is disposed on the pin to rotate along with the pin relative to the seat 210, so that the gear engages with the transmission engaging portion 130 to rotate the seat 210 relative to the mounting seat 100. It should be noted that the link mechanism may be a rocker structure driven by a motor or an air cylinder, and the rocker is connected to the rotating member, so that when the rocker performs a crank-rocker motion, the rotating member rotates relative to the base 210.

With continued reference to fig. 3 and 4, the mounting base 100 is provided with a baffle ring 140, the baffle ring 140 is disposed around the first axis w1, the engaging portion 130 is located outside the baffle ring 140, and the baffle ring 140 and the base 210 define an annular cavity 141. The mounting base 100 is provided with a first wire passing hole 102 communicated with the annular cavity 141, the base body 210 is provided with a second wire passing hole 212 communicated with the annular cavity 141, and a wire can enter from the outside and pass through the first wire passing hole 102 and the second wire passing hole 212 to be connected with electrical components such as a motor on the base body 210.

In this embodiment, since the first wire hole 102 and the second wire hole 212 are located in the annular cavity 141 surrounded by the baffle ring 140, and the engaging portion 130 is located outside the baffle ring 140, the wire connected to the motor 310 is blocked by the baffle ring 140, so that the wire is prevented from entering the engaging portion 130 and interfering with the engaging transmission between the transmission portion 222 and the engaging portion 130, the working stability of the rotating assembly 200 is improved, and the wire is prevented from being damaged.

In some embodiments, the first wire passing hole 102 penetrates from the side of the mounting portion 110 to the annular cavity 141, so that the wire can enter the annular cavity 141 through the side of the mounting portion 110, and pass through the base 210 through the second wire passing hole 212 to be connected with corresponding electrical components such as a motor.

As shown in fig. 1 and fig. 4 to fig. 6, a power source such as a motor 340 may be used to drive the driving gear 310 to engage with the transmission gear 320, so that the transmission gear 320 drives the swing arm 330 connected thereto to rotate about the second axis w 2. As in some embodiments, the drive gear 310 is coupled to an output shaft of the motor 340.

In some embodiments, the swing arm 330 has opposite rotating end 331 and swinging end 332, wherein the rotating end 331 is rotatably connected to the base 210, and the swing arm 330 is provided with a transmission gear 320 capable of being engaged with the driving gear 320 near the rotating end 331. The motor 310 is disposed in the base 210, and an output shaft of the motor 310 is connected to the driving gear 320, and when the motor 310 drives the driving gear 320 to rotate, the driving gear 320 is engaged with the transmission gear 320, so that the swing arm 330 rotates relative to the base 210. The RFID reader 400 is connected to the swing end 332 and driven by the swing arm 330 to face different directions. Thus, under the action of the swing assembly 300, the RFID reader 400 can rotate around the rotation end 331 to realize a scanning motion within 2 dimensions in cooperation with the rotation of the base 210 relative to the mount 100 around the first axis w 1. Taking the mounting base 100 mounted on the ceiling as an example, assuming that the mounting base 100 is substantially vertically mounted on the ceiling with the first axis w1, when the base 210 rotates around the first axis w1, the swing arm 330 can drive the RFID reader 400 to rotate in the horizontal plane. When the swing arm 330 rotates up and down, the RFID reader 400 can perform a pitching motion. That is to say, the RFID reader 400 can rotate horizontally and also move in a pitching manner under the action of the rotating component 200 and the swinging component 300, so that the RFID reader 400 can perform all-directional scanning on a space to be scanned, and the scanning space of the RFID reader 400 can be effectively extended.

Referring to fig. 2, 4 and 5, the base 210 includes two opposite support frames 211, the swing arm 330 has a rotating shaft 333, and the swing arm 330 is rotatably connected between the two support frames 211 through the rotating shaft 333, that is, the swing arm 330 can rotate between the two support frames 211 around the rotating shaft 333. It can be understood that the longitudinal axis of the rotating shaft 333 coincides with the second axis w2 because the two supporting frames 211 are located at two sides of the swing arm 330, so that the swing arm 330 is not biased to one side when rotating, and the swing arm 330 can stably drive the RFID reader-writer 400 to rotate, thereby meeting the scanning requirements of the RFID reader-writer 400.

As shown in fig. 6, the periphery of the transmission gear 320 is provided with a meshing tooth 321 meshed with the driving tooth 320, and the center of circle of the transmission gear 320 is located on the rotation axis of the rotation shaft 333, that is, the center of circle of the transmission gear 320 is located on the second axis w2, so that when the driving tooth 320 is driven by the motor 310 to rotate, the transmission gear 320 can be meshed to rotate around the second axis w2, and the swing arm 330 rotates around the second axis w2 relative to the seat body 210.

In some embodiments, the transmission gear 320 has a hollowed-out portion 322, thereby reducing weight, enabling a greater torque to be obtained by the swing arm 330. The transmission gear 320 can be arranged on the swing arm 330 in an integrated forming mode, so that the structural strength is high, and the transmission gear 320 cannot be loosened to influence the meshing transmission effect.

It should be noted that the outer circumference of the transmission gear 320 may be a semicircular arc, or may be an arc with a central angle of 60 ° to 135 °, that is, the central angle of the outer circumference of the transmission gear 320 is 60 ° to 135 °. Therefore, the RFID reader-writer can rotate at a proper angle under the meshing of the driving teeth 320, so that the swing arm 330 drives the RFID reader-writer 400 to rotate within a reasonable range, and the problems that the scanning area cannot be fully utilized due to too large meshing transmission swing amplitude, the circulating scanning stroke is wasted, and the effective scanning efficiency is influenced are avoided. Specifically, the swing amplitude of the swing arm 330 is limited to a certain extent by the arrangement of the transmission gear 320, and the swing arm 330 only scans the area where the articles to be detected are stored under the limitation of the meshing stroke of the transmission gear 320, so that the scanning read-write efficiency of the RFID reader-writer 400 is effectively improved. In some embodiments, the outer circumference of the drive gear 320 corresponds to a central angle of 90 °.

As shown in fig. 2 and fig. 7, a cover 240 is connected to a side of the base 210 facing away from the mounting base 100, and a receiving cavity 241 is defined between the cover 240 and the base 210. The housing 240 is provided with a slot 242 communicated with the accommodating cavity 241, and the driving element 220 and the driving gear 310 are located in the accommodating cavity 241, so that the housing 240 is utilized to prevent the internal structure from being exposed, the appearance is attractive, and meanwhile, foreign objects are prevented from entering the seat body 210 to influence the effective work of the driving element 220 and the driving gear 310. In this embodiment, the swing arm 330 is movably disposed through the slot 242, so that the swing arm 330 can adjust the spatial posture of the RFID reader-writer 400, i.e., the orientation of the RFID reader-writer 400, so that the RFID reader-writer 400 can perform scanning movement, thereby increasing the identification reading area.

As shown in fig. 8 and 9, a side of the cover 240 facing away from the base 210 is raised outward to form a raised portion 243, and the rotating shaft 333 is received in the raised portion 243. In this embodiment, the protrusion 243 accommodates the rotating end 331, so that the housing 240 can be made smaller at other places, and the overall structure is more compact and occupies a smaller space. It should be noted that the notch 242 is formed on the protruding portion 243, so that when the transmission gear 320 drives the swing arm 330 to rotate around the rotating shaft 333, the transmission gear 320 can move at the notch 242, and the notch 242 provides a good clearance effect, so as to avoid interference with the movement of the swing arm 330 and the transmission gear 320.

Correspondingly, as shown in fig. 10, the present application further provides a scanning method, where the scanning method includes the steps of:

step S102 provides the above-mentioned scanning device 10.

Step S104, the RFID reader 400 is turned on, so that the RFID reader 400 performs radio frequency information identification reading and writing.

Specifically, the RFID (Radio Frequency Identification) technology is also called an electronic tag technology, and is a non-contact automatic Identification technology, and the basic working principle of the technology is to utilize Radio Frequency signals and inductance or electromagnetic space coupling transmission characteristics to realize automatic Identification of an identified object. RFID systems generally consist of three parts: RFID electronic tags (Tag), readers (Reader) and computer application systems.

The basic workflow of the RFID system is as follows: the electronic tag reader-writer sends a radio frequency signal with a specific working frequency through a radio frequency transmitting antenna, when the electronic tag enters a working coverage area of the reader-writer transmitting antenna, the antenna of the electronic tag reader-writer generates induced current through inductance or electromagnetic space coupling, and a passive tag is activated (for an active tag, the passive tag does not need to be activated and is always in a working state); one part of energy obtained by the label is rectified into a direct current power supply to be supplied to an electronic circuit in the label for working, and the other part of energy is modulated by data information stored in the label and then reflected to a label reader-writer through a label antenna; the tag reader receives the carrier signal reflected from the electronic tag through the receiving antenna, demodulates and decodes the received signal to obtain the identification data information stored in the electronic tag, and sends the identification data information to the computer application system through the communication interface for processing.

In step S106, the driving member 220 drives the seat 210 to rotate relative to the mounting seat 100, and the seat 210 drives the RFID reader 400 to rotate around the first axis w1 via the swing arm 330.
