FIG. 1 is a theoretical block diagram of an automatic RFID-based flush character engraving system in an embodiment.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, the automatic carving system for the flush joint character based on the RFID provided in this embodiment includes a first detection device, a second detection device, an RFID device, an industrial personal computer, and a laser machine, where the first detection device, the second detection device, the RFID device, and the laser machine are all in communication connection with the industrial personal computer.
The first detection means are used to detect whether a product with an RFID tag enters the identification zone and the second detection means are used to detect whether a product enters the engraving zone. Photoelectric sensors are preferably adopted by the first detection device and the second detection device, the detection accuracy of the photoelectric sensors is high, and errors are avoided. The photoelectric sensor comprises a transmitter and a receiver, when the product enters the identification area or the carving area, the product can block the optical signal transmitted by the transmitter, and then the optical signal cannot be received by the receiver.
After the first detection device detects that the product enters the identification area, a trigger signal is sent to the industrial personal computer, the industrial personal computer immediately sends a tag reading instruction to the RFID equipment, and the RFID equipment starts to read data in the RFID tag carried by the product after receiving the tag reading instruction. The RFID label data contains the neat seam characters to be carved, the RFID equipment transmits the neat seam characters to the industrial personal computer after collecting the neat seam characters, and the industrial personal computer transmits the neat seam characters to the laser machine.
The RFID device is a device for identifying the RFID label, preferably a dual-frequency RFID device, and can identify the ultrahigh frequency RFID label and the high frequency RFID label, so that the applicability is enhanced.
After the second detection device detects that the product enters the carving area, the trigger signal is sent to the industrial personal computer, and the industrial personal computer sends a carving instruction to the laser machine. And after receiving the engraving instruction, the laser machine executes engraving operation, namely engraving the flush characters in the RFID label on the product.
It will be readily appreciated that in the arrangement of the apparatus, with the direction of advance of the products on the conveyor being the positive direction, the first detection means is rearwardmost, the RFID device is in front of the first detection means, the second detection means is in front of the RFID device and the laser machine is in front of the second detection means. It should also be noted that the front and rear herein do not necessarily refer to absolute front and rear in physical position, but to a logical mutual order of execution.
In the traditional method, characters are stored in a laser machine in advance, and once the transportation sequence of products is wrong or a certain product is repeatedly engraved, the characters of all the products are wrong. The invention stores the characters in the RFID label, and the label is arranged on the product, namely the product and the characters are in one-to-one correspondence, so that the phenomena of repeated codes, missing codes and wrong codes can be avoided, full-automatic carving can be realized, and the efficiency is improved.
As shown in FIG. 1, the system may further include an alarm device in communication connection with the industrial personal computer, and when the RFID device fails to recognize the RFID tag, an alarm signal may be sent out. The alarm device can adopt an acousto-optic alarm lamp. By arranging the alarm device, the industrial personal computer controls the alarm device to send out an alarm signal when the identification fails so as to inform workers of timely processing.
As shown in FIG. 1, the system can also comprise a removing device in communication connection with the industrial personal computer. When the RFID equipment fails to recognize the RFID label, a trigger signal is sent to the industrial personal computer, the industrial personal computer sends a rejection instruction to the rejection device, and the rejection device rejects the product after receiving the rejection instruction. Through setting up the removing devices, remove this product when discerning the failure to this ensures that every qualified product has carved with corresponding concatenation character. The removing device can be a deflector rod removing device or a mechanical arm, and when a removing instruction is received, the product is removed from the conveying belt.
Since each device in the system is an existing product that can be purchased directly from the market, a specific structure of each device is not given in this embodiment. For example, the photoelectric sensor can be selected from a Panasonic EX-10 series product, the laser machine can be selected from a Kenzhi MD-X series product, the industrial personal computer can be selected from a Yinghonong 720 series product, the alarm device can be selected from an alarm lamp, such as a BJ100 alarm lamp of Phoenix lighting company, and the removing device can be a deflector rod removing device (such as a deflector rod removing device in a Kaxon electronic AEC500C series product), a manipulator and the like.
Based on the system implementation, it can also be considered that the present embodiment also provides an automatic carving method for a flush-joint character based on RFID, where the method specifically includes the following steps:
step 1, detecting whether a product with an RFID label enters an identification area, if not, continuing to detect, and if so, reading data in the RFID label and transmitting a flush joint character in the data to a laser machine.
More specifically, when the fact that a product enters the identification area is detected, the photoelectric sensor sends a trigger signal to the industrial personal computer, the industrial personal computer triggers the RFID equipment to read data in the RFID label, and the laser machine is transmitted to the flush joint characters in the data.
When the RFID equipment fails to identify the RFID label (namely data in the RFID label is not identified), an alarm trigger signal can be sent to the alarm device, so that the alarm device sends an alarm signal, such as an audible and visual alarm signal.
When the RFID equipment fails to identify the RFID label, a rejecting instruction can be sent to a rejecting device so as to reject the product which fails to be identified.
And 2, detecting whether the product enters the carving area or not, if not, continuing to detect, and if so, sending a carving instruction to the laser machine.
More specifically, when a product enters a carving area, the photoelectric sensor sends a trigger signal to a PLC of the industrial personal computer, and the industrial personal computer sends a carving instruction to the laser machine.
And 3, executing the engraving operation after the laser machine receives the engraving instruction, and engraving the received flush characters on the product.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention.
