DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Combine the following Figure 1-Figure 5 The utility model is described as a sliding component positioning and communication mechanism, including: a sliding member 100, which is used to be movably connected with a guide rail 101; an optical communication module 200, which is arranged on the sliding member 100; an energy storage module 300, which is arranged on the sliding member 100, and the energy storage module 300 is connected with the optical communication module 200 to supply power to the optical communication module 200; a communication circuit board fixing member 400, which is used to be connected with a machine body, and the communication circuit board fixing member 400 is provided with a first processing unit 410 and a plurality of first optical transceiver devices 420, the first processing unit 410 is connected with the first optical transceiver device 420, and the plurality of first optical transceiver devices 420 are arranged to form an optical device queue 421; the sliding member 100 moves along the guide rail 101 to drive the optical communication module 200 to move along the optical device queue 421, and the optical communication module 200 is used to transmit and receive optical signals toward the first optical transceiver device 420.

[0032] A plurality of first optical transceiver devices 420 are arranged on the communication circuit board fixing part 400 to form a structure of an optical device queue 421. When the sliding part 100 moves along the guide rail 101, the optical communication module 200 on the sliding part 100 also moves along the optical device queue 421. The optical communication module 200 can exchange optical signals with the corresponding first optical transceiver devices 420 at different positions. The first processing unit 410 can determine the position of the sliding part 100 according to the position of the first optical transceiver device 420 for optical signal exchange. At the same time, the first processing unit 410 can also perform optical communication with the optical communication module 200 through the first optical transceiver device 420. The first processing unit 410 can be connected to the controller so that the controller and the optical communication module 200 can communicate with each other.

[0033] refer to Figure 1 , Figure 4 and Figure 5 In actual use, the sliding member 100 is installed on the guide rail 101 of the machine tool, and the communication circuit board fixing member 400 is installed on the fixing machine. At the same time, the optical communication module 200 on the sliding member 100 corresponds to the first optical transceiver device 420 on the communication circuit board fixing member 400. The optical device queue 421 formed by multiple first optical transceiver devices 420 extends along the moving path of the sliding member 100 on the guide rail 101, that is, the optical communication module 200 can maintain optical communication with the optical device queue 421 as the sliding member 100 moves.

[0034] In this way, the optical communication module 200 uses optical communication to eliminate the need to connect communication cables to the sliding member 100. The energy storage module 300 supplies power to the optical communication module 200, so that the sliding member 100 does not need to be connected to power cables. The combination of the two achieves the purpose of eliminating the need to connect electrical cables to the sliding member 100. At the same time, the optical communication module 200 cooperates with the structure of the optical device queue 421 to achieve the effect of positioning the sliding member 100 and communicating. When the sliding member 100 is not connected to an electrical cable, the movement state of the sliding member 100 can be known and data can be collected from other devices on the sliding member 100 by optical communication, which is beneficial to avoid the impact of the sliding member 100 being connected to an electrical cable, improve reliability and reduce maintenance difficulty.

[0035] The optical device queue 421 formed by the plurality of first optical transceiver devices 420 may be in a straight line, a curve, etc., and the shape of the optical device queue 421 depends on the moving path of the optical communication module 200. In some embodiments of the present invention, the energy storage module 300 may be an implementation including a lithium-ion battery, a nickel-hydrogen battery, a lead-acid battery, etc.

[0036] refer to Figure 2 , Figure 4 and Figure 5In some embodiments of a sliding component positioning and communication mechanism provided by the present invention, a plurality of the first optical transceiver devices 420 are arranged equidistantly to form the optical device queue 421, and the area where the optical communication module 200 transmits the optical signal covers at least two adjacent first optical transceiver devices 420.

[0037] In order to maintain the stability of optical communication during the movement of the sliding member 100, the first optical transceiver devices 420 in the optical device queue 421 are arranged equidistantly, that is, the distance between two adjacent first optical transceiver devices 420 is equal, and at the same time, the area where the optical communication module 200 transmits the optical signal can cover at least two adjacent first optical transceiver devices 420, so that during the movement of the optical communication module 200, the area that transmits the optical signal in the direction of the communication circuit board fixing member 400 will at least completely cover at least one first optical transceiver device 420, that is, it is ensured that the optical signal emitted by the optical communication module 200 will not be lost and the first optical transceiver device 420 will continue to convert the optical signal into an electrical signal and transmit it to the first processing unit 410, thereby achieving the effect of ensuring stable communication between the optical communication module 200 and the first processing unit 410.

[0038] It is understandable that during the movement of the optical communication module 200, the area that transmits the optical signal toward the communication circuit board fixture 400 at least completely covers at least one first optical transceiver device 420. Since the optical path is reversible, the optical communication module 200 will also completely receive the optical signal transmitted by at least one first optical transceiver device 420. In some embodiments of the present utility model, each first optical transceiver device 420 in the same optical device array 421 transmits the same optical signal under the control of the first processing unit 410, so that the optical communication module 200 can receive continuous optical signals during the movement, and the optical communication module 200 and the first processing unit 410 can communicate bidirectionally.

[0039] refer to Figure 4 and Figure 5 In some embodiments of a sliding component positioning and communication mechanism provided by the utility model, the optical communication module 200 includes a second processing unit 210, a communication head 220 and a second optical transceiver device 230, the second processing unit 210 and the communication head 220 are arranged on the sliding member 100, the communication head 220 is provided with a cavity 240, the second optical transceiver device 230 is arranged in the cavity 240, the second optical transceiver device 230 is connected to the second processing unit 210, and the opening projection of the cavity 240 can cover at least two adjacent first optical transceiver devices 420.

[0040] The communication head 220 is provided with a cavity 240 and the second optical transceiver device 230 is arranged in the cavity 240, so that the optical signal transmitted and received by the second optical transceiver device 230 needs to pass through the opening of the cavity 240, so that the size of the opening of the cavity 240 can be controlled to achieve the purpose of controlling the size of the optical signal coverage area. The opening projection of the cavity 240 covers at least two adjacent first optical transceivers 420 to ensure stable communication during movement. The second processing unit 210 communicates with the first processing unit 410 through the second optical transceiver device 230 and the first optical transceiver device 420.

[0041] In some embodiments of the present invention, the first processing unit 410 and the second processing unit 210 may be devices including single chip microcomputers, FPGAs, embedded chips, etc., which have control processing functions, and the types of devices included in the first processing unit 410 and the second processing unit 210 may be the same or different. The first optical transceiver device 420 and the second optical transceiver device 230 may be implementations including devices such as photodiodes and light emitting diodes, and realize the functions of converting electrical signals into optical signals and converting optical signals into electrical signals.

[0042] refer to Figure 2 In some embodiments of a sliding component positioning and communication mechanism provided by the utility model, it also includes a first communication bus 500 and a second communication bus 600, there are at least two communication circuit board fixing parts 400, and the communication circuit board fixing parts 400 are connected to each other so that the optical device queues 421 on each of the communication circuit board fixing parts 400 are spliced ​​end to end, and one of the first processing units 410 on two adjacent communication circuit board fixing parts 400 is connected to the first communication bus 500, and the other is connected to the second communication bus 600.

[0043] When the sliding member 100 moves a long distance, multiple communication circuit board fixtures 400 need to be spliced, so that the optical device array 421 on each communication circuit board fixture 400 is also spliced, and the entire optical device array 421 is extended to meet the moving distance requirement. At the same time, considering that each communication circuit board fixture 400 has a first processing unit 410, when the communication head 220 moves to the junction of adjacent communication circuit board fixtures 400, it may communicate with two first processing units 410 at the same time. In this regard, by setting up a first communication bus 500 and a second communication bus 600, one of the two adjacent first processing units 410 is connected to the first communication bus 500, and the other is connected to the second communication bus 600. The first processing units 410 with odd numbers can be connected to the first communication bus 500, and the first processing units 410 with even numbers can be connected to the second communication bus 600. When the second processing unit 210 communicates with two adjacent first processing units 410 at the same time, data signals are uploaded through the first communication bus 500 and the second communication bus 600 respectively, which can avoid conflicts between the signals generated by the two adjacent first processing units 410 and improve the reliability of communication.

[0044] It is understandable that, when the moving distance of the sliding member 100 is short, only one communication circuit board fixing member 400 may be used for implementation.

[0045] In actual applications, such as when used on a machine tool, a controller such as a PLC controller is usually provided. The second processing unit 210 needs to be connected to the controller to realize communication and upload data signals. The first processing units 410 arranged in odd numbers are connected to the controller via a first communication bus 500, and the second processing units 210 arranged in even numbers are connected to the controller via a second communication bus 600.

[0047] The specific structure of the communication head 220 includes a bracket 221, a telescopic rod 222 and a mounting seat 223. The bracket 221 is used to connect with the sliding member 100 to achieve a fixing effect. The telescopic rod 222 can adjust the position of the mounting seat 223. The mounting seat 223 is provided with the above-mentioned concave cavity 240, and the second optical transceiver 230 is installed in the concave cavity 240 of the mounting seat 223. The telescopic rod 222 is telescoped to adjust the distance between the opening of the concave cavity 240 on the mounting seat 223 and the first optical transceiver 420, so as to adapt to different application environments.

[0048] refer to Figure 4 and Figure 5 In some embodiments of a sliding component positioning and communication mechanism provided by the utility model, a cleaning comb 250 is provided on the opening wall surface of the cavity 240 formed by the mounting seat 223, and the cleaning comb 250 is used to contact the communication circuit board fixing part 400 to clean the first optical transceiver device 420.

[0049] A cleaning comb 250 is arranged on the opening wall surface of the cavity 240 formed by the mounting seat 223. When the sliding member 100 moves along the guide rail 101, the cleaning comb 250 contacts the communication circuit board fixing member 400, so as to remove dust and impurities on the communication circuit board fixing member 400 and the first optical transceiver device 420, thereby preventing dust from affecting the reception and transmission of optical signals by the first optical transceiver device 420, improving the reliability of optical signal interaction between the first optical transceiver device 420 and the optical communication module 200, i.e., the second optical transceiver device 230, and improving the stability of communication between the first processing unit 410 and the second processing unit 210.

The second processing unit 210 controls the start and stop of the driving module 700 to achieve the effect of controlling the sliding member 100 to move or stop along the guide rail 101.

[0052] In some embodiments of the present invention, the driving module 700 may be an implementation including a motor and a roller, the roller abuts against the guide rail 101, and the motor is connected to the roller to drive the roller to rotate forward, rotate backward or stop, thereby driving the sliding member 100 to move or stop along the guide rail 101.

[0054] The sensor module 800 is set on the sliding member 100, and can perform detection as the sliding member 100 moves. The detection signal generated by the sensor module 800 is transmitted to the optical communication module 200, which is actually transmitted to the second processing unit 210. The second processing unit 210 controls the second optical transceiver device 230 to transmit the detection signal to the first processing unit 410 through optical communication. Then the first processing unit 410 uploads the detection signal to the controller, thereby achieving data signal collection without the need for cable connection.

The tension sensor 810 generates a corresponding tension signal according to the magnitude of the tension received, and the angle sensor 820 generates a corresponding angle signal according to the angle change. The optical communication module 200 obtains the tension signal and the angle signal, and transmits the tension signal and the angle signal to the first processing unit 410 via optical communication, and then the first processing unit 410 uploads the tension signal and the angle signal.
