Description

Technical Field

[0001] The present invention relates to the technical field of data acquisition, and particularly to an RFID multi-directional acquisition device. Background Art

[0002] Data acquisition refers to automatically collecting non-electric or electric signals from analog and digital measured units such as sensors and other devices to be measured, and sending them to a host computer for analysis and processing. A data acquisition system is a flexible and user-defined measurement system realized by combining measurement software and hardware products based on a computer or other dedicated test platforms. The data to be collected are various physical quantities that have been converted into electrical signals, such as temperature, water level, wind speed, pressure, etc., which can be analog or digital. The acquisition is generally in a sampling manner, that is, the same point data is repeatedly collected at regular intervals. Most of the collected data are instantaneous values, or can also be a characteristic value within a certain period of time. Accurate data measurement is the basis of data acquisition. The data measurement methods include contact type and non-contact type, and there are various detection elements. The RFID data acquisition solution is a non-contact automatic identification technology. It automatically identifies target objects through radio frequency signals and obtains relevant data. The identification work does not require manual intervention and can work in various harsh environments, not afraid of harsh environments such as oil stains and dust pollution. It can replace barcodes in such environments. The RFID data acquisition solution can identify high-speed moving objects and can simultaneously identify multiple tags, with fast and convenient operation. The RFID data acquisition solution mainly consists of a front-end data acquisition device, a transmission device, a system server, and relevant data acquisition software, system software, and a database. The RFID data acquisition solution directly reads the parameters of devices such as PLCs through an industrial bus, and at the same time collects data of various operating devices, operating processes, and operating environments in the industrial field through deployed sensing devices and RFID devices, and then transmits these data to a data acquisition server (SCADA) through the industrial bus, optical fiber, or wireless network, and stores them in a database server. After the collected data passes through a publishing server, it can be used to monitor the industrial field in real time in a central control room. Dispatching and management personnel can remotely log in to the publishing server through a browser to monitor the industrial field in real time within their authorized scope or obtain operation data;

[0003] Most of the existing RFID-based data acquisition devices are handheld devices. During use, when collecting RFID data for multiple items, workers need to hold the data acquisition device and sequentially collect RFID data for multiple items, which takes a relatively long time and results in low efficiency. At the same time, since the data acquisition device needs to work in the factory, most workers will set up a protective case and a scanning window outside the data acquisition camera. However, there is a lot of dust inside the factory, which will cause a lot of dust to accumulate on the scanning window, thus affecting the scanning effect of the camera. To solve the above problems, the inventor proposes an RFID multi-directional acquisition device to solve the above problems. Summary of the Invention

[0029] Embodiment: As Figures 1-8As shown in the figure, the present invention provides a technical solution: an RFID multi-directional acquisition device, including a conveying mechanism 1. Symmetrically fixed to the center near both side ends of the conveying mechanism 1 are vertical plates 101. Between the tops of the two vertical plates 101 is fixedly connected a lifting assembly 2. Near the center of the bottom of one side of one of the vertical plates 101 is fixedly connected a controller 102. Between the two vertical plates 101 and below the lifting assembly 2 is provided an acquisition assembly 3. On the side of the two vertical plates 101 away from the lifting assembly 2 and near the center of the bottom are symmetrically provided bottom grooves. Threadedly rotatably connected to the side of the vertical plate 101 at the bottom groove are two groups of bolts. The reason for providing the bottom groove on the side of the vertical plate 101 is to install two groups of symmetrically distributed bolts for fixing the vertical plate 101 on the conveying mechanism 1, thereby realizing the convenient disassembly of the two vertical plates 101 and facilitating installation on different conveying mechanisms 1. For the working conveying mechanism 1, the articles are moved. When the articles move below the top plate 201, they can be stopped. Then, the acquisition scanning head body 311 can be activated to acquire and scan the information of the articles below. The first support plate 204 is lifted and lowered under the action of the two guiding telescopic rods 203 to adjust the distance between the acquisition scanning head body 311 and the articles. By turning on the auxiliary lamp 307, it is convenient to improve the scanning accuracy of the acquisition scanning head body 311.

[0031] By adopting the above technical solution, guiding telescopic rods 203 are symmetrically arranged near the center of the bottom end of the top plate 201 to facilitate the electric cylinder 202 to drive the first support plate 204 to lift and lower. When the electric cylinder 202 operates, the first support plate 204 can be lifted and lowered under the action of the two guiding telescopic rods 203, thereby realizing the function of adjusting the distance between the acquisition scanning head body 311 and the articles.

[0032] At the center of the top end of the second support plate 205 is fixedly connected a square platform 207. At the center of the top end of the square platform 207 is rotatably connected a rotating frame 208. At the center of the bottom end of the first support plate 204 is fixedly connected a first motor 206. The output end of the first motor 206 is fixedly connected to the rotating frame 208. Fixedly connected to the side of the rotating frame 208 is a rotating frame 209.

[0033] By adopting the above technical solution, the motor one 206 is operated, so that the fixedly connected rotating frame 208 drives the rotating frame 209 to move under the action of the auxiliary wheel 213, realizing the effect of moving the acquisition scanning head body 311. The rotating frame 208 drives the rotating frame 209 to move along a rectangular trajectory under the action of the spring 211, the slider 210 and the auxiliary wheel 213, thereby realizing the effect of moving the acquisition scanning head body 311 along a rectangular trajectory, which is convenient for improving the accuracy of item acquisition work.

[0034] A slider 210 is slidably connected between the side walls of the rotating frame 209. A spring 211 is fixedly connected to the side end of the slider 210, and the other end of the spring 211 is fixedly connected to the inner wall of the rotating frame 209.

A second connecting shaft 214 is slidably connected inside the square groove 215 opened near the center inside the second support plate 205, and the top end of the second connecting shaft 214 is fixedly connected to the rotating frame 209.

[0035] By adopting the above technical solution, the auxiliary wheel 213 is provided to cooperate with the slider 210, the spring 211 and the first connecting shaft 212 to realize the effect of the auxiliary rotating frame 208 driving the second connecting shaft 214 to move, which is convenient for improving the accuracy of item acquisition work.

[0036] The acquisition component 3 includes a third support plate 301, and the top end of the third support plate 301 is fixedly connected to the second connecting shaft 214. A side plate 302 is fixedly connected to the bottom end of the third support plate 301 near one side. A fourth support plate 304 is fixedly connected below the side plate 302. A rotating shaft 308 is rotatably connected to the bottom end of the side plate 302 near the center of one side. A motor two 303 is fixedly connected to the top end of the third support plate 301 near the center of one side. The output end of the motor two 303 penetrates through the side plate 302 and is fixedly connected to the rotating shaft 308.

[0037] By adopting the above technical solution, the motor two 303 is operated, so that the fixedly connected rotating shaft 308 rotates, thereby enabling the fixedly connected L-shaped frame 306 to drive the auxiliary lamp 307 to move under the action of the annular groove 305, realizing the effect of adjusting the position of the auxiliary lamp 307, which is convenient for the acquisition scanning head body 311 to work.

[0038] An annular groove 305 is opened inside the fourth support plate 304. An L-shaped frame 306 is slidably connected inside the annular groove 305, and the top end of the L-shaped frame 306 is fixedly connected to the rotating shaft 308.

A protection box 309 is fixedly connected to the bottom end of the third support plate 301 near the other side.

[0039] By adopting the above technical solution, an annular groove 305 is provided inside the support plate four 304 so that the L-shaped frame 306 can cooperate with the rotating shaft 308 to drive the auxiliary lamp 307 to adjust the angle. The motor two 303 is operated, so that the fixedly connected rotating shaft 308 drives the L-shaped frame 306 to move inside the annular groove 305, thereby achieving the effect of adjusting the angle of the auxiliary lamp 307 and facilitating the auxiliary lamp 307 to provide the best lighting angle.

[0040] At the top end of the inside of the protection box 309 and near the center of one side, a mounting seat 310 is fixedly connected. At the bottom end of the mounting seat 310, a collection and scanning head body 311 is fixedly connected. At the bottom end of the protection box 309 near the center, a mounting groove 312 is provided. Inside the mounting groove 312 at the bottom end of the protection box 309, an observation window 313 is fixedly connected. At the bottom end of the protection box 309 and near the center of one side, a turntable 314 is rotatably connected. At the bottom end of the turntable 314 and near the outer ring, a short shaft one 315 is fixedly connected.

[0041] By adopting the above technical solution, the mounting seat 310 is provided inside the protection box 309 to mount and fix the collection and scanning head body 311, and the collection and scanning head body 311 is installed obliquely to facilitate the completion of the collection and scanning work.

[0042] At the bottom end of the protection box 309 and near one side of the observation window 313, a sliding groove 316 is provided, and the sliding groove 316 is at the same horizontal level as the turntable 314. Inside the sliding groove 316, a pushing plate 317 is slidably connected.

[0043] By adopting the above technical solution, after the turntable 314 rotates, with the mutual cooperation among the short shaft one 315, the short shaft two 319 and the connecting rod 320, the pushing plate 317 can drive the cleaning brush 318 to move back and forth, achieving the effect of cleaning the observation window 313.

[0044] A cleaning brush 318 is fixedly connected to the side end of the pushing plate 317, and the cleaning brush 318 is in contact with the observation window 313. At the bottom end of the pushing plate 317 and near one side, a short shaft two 319 is fixedly connected. A connecting rod 320 is rotatably connected between the outer circles of the short shaft two 319 and the short shaft one 315.

[0045] By adopting the above technical solution, the pushing plate 317 drives the cleaning brush 318 to move back and forth, achieving the effect of cleaning the observation window 313, thereby realizing the work of removing dust from the surface of the observation window 313.

[0046] At the bottom end of the inside of the protection box 309 and near the center of one side, a motor three 321 is fixedly connected. The output end of the motor three 321 penetrates the protection box 309 and is fixedly connected to the turntable 314. At the side end of the protection box 309 and near the motor three 321, a heat dissipation port 322 is provided.

[0047] By adopting the above technical solution, it is possible to prevent the collection and scanning head body 311 from being unable to accurately perform the scanning and collection work due to dust. By providing the heat dissipation port 322, it is convenient to dissipate the heat generated by the motor three 321.

[0048] Working principle: When the present invention is in use, first place the item to be collected on the conveying mechanism 1, and then operate the conveying mechanism 1 to move the item. Stop when the item moves below the top plate 201. Then, the collection and scanning head body 311 can be turned on to collect and scan the information of the item below. By operating the electric cylinder 202, the first support plate 204 fixedly connected thereto can be lifted and lowered under the action of the two guiding telescopic rods 203 to adjust the distance between the collection and scanning head body 311 and the item. By operating the first motor 206, the rotating frame 208 can drive the rotating frame 209 to move in a rectangular trajectory under the action of the spring 211, the slider 210 and the auxiliary wheel 213, thereby achieving the effect of the collection and scanning head body 311 moving in a rectangular trajectory, which is convenient for improving the accuracy of item collection. When the collection is inaccurate due to poor visibility, turning on the auxiliary lamp 307 can facilitate improving the scanning accuracy of the collection and scanning head body 311. By the second motor 303, the fixedly connected rotating shaft 308 can drive the L-shaped frame 306 to move inside the annular groove 305, thereby achieving the effect of adjusting the angle of the auxiliary lamp 307, facilitating the auxiliary lamp 307 to provide the best lighting angle, and further solving the problem that most existing RFID-based data collection devices are handheld devices. During use, when collecting RFID data for multiple items, the staff needs to hold the data collection device and collect RFID data for multiple items in sequence, which takes a long time.

[0049] The collection and scanning head body 311 needs to complete the scanning work through the observation window 313. However, dust will accumulate on the observation window 313 after long-term work in the workshop or factory. By operating the third motor 321, the fixedly connected turntable 314 can be rotated. Then, under the mutual cooperation of the first short shaft 315, the second short shaft 319 and the connecting rod 320, the pushing plate 317 can move horizontally back and forth inside the sliding groove 316, thereby driving the fixedly connected cleaning brush 318 to move back and forth on the surface of the observation window 313, thereby achieving the work of removing dust from the surface of the observation window 313, preventing the collection and scanning head body 311 from being unable to accurately perform the scanning and collection work due to dust, and further solving the problem that the data collection device needs to work in the factory, so that most staff will set a protective shell and a scanning window outside the data collection camera. However, there is a lot of dust inside the factory, which will cause a lot of dust to accumulate on the scanning window, ultimately affecting the scanning effect of the camera.

[0050] Obviously, those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these modifications and variations.
