[0002] At present, in the production process of membrane gas meters, writing the parameters of the circuit board is an important link. In the process of writing the parameters, after the assembled gas meter is transported to the parameter writing station by the conveyor belt, the conveyor motor stops, the conveyor belt is in a shutdown state, and the parameter writing device configures the parameters of the circuit board input data. After the circuit board parameters are written, the conveyor motor starts, and the conveyor belt transports the next gas meter to the parameter writing station, and repeats in sequence. Frequent starting and stopping of the conveyor motor will cause additional wear on the mechanical parts inside the conveyor motor, accelerate its aging and damage, and reduce the service life of the conveyor motor, so further improvement is needed. Summary of the invention

[0003] In order to reduce the possibility of frequent start and stop operations of the conveying motor and to increase the service life of the conveying motor, the present application provides a gas meter circuit board writing parameter conveying device.

[0004] The present application provides a gas meter circuit board parameter writing and transmission device that adopts the following technical solution:

[0005] The conveying device of a gas meter circuit board comprises a conveying frame, a conveying belt arranged on the conveying frame to convey the gas meter, and a writing parameter mechanism arranged on one side of the conveying frame. Both ends of the conveying frame are rotatably connected with conveying rollers, the conveying belt is wound around the two conveying rollers, the conveying frame is provided with a conveying motor that drives the conveying rollers to rotate. The conveying frame is slidably connected with a moving platform along the conveying direction of the conveying belt, the conveying belt protrudes and is fixedly connected with a push plate, the push plates are provided with multiple and are distributed at intervals along the length direction of the conveying belt, the moving platform is hinged with a limit plate parallel to the push plate, the free end of the limit plate is normally located on the moving path of the push plate so that the push plate abuts against the limit plate, thereby forcing the moving platform to move with the conveying belt, the moving platform or the conveying frame is provided with a limit driving assembly that drives the free end of the limit plate to swing up and down, the base is provided with a first elastic member that forces the moving platform to retreat, and the writing parameter mechanism is provided on the moving platform.

[0006] By adopting the above technical solution, under normal conditions, the free end of the limit plate swings downward so that the free end of the limit plate is located on the moving path of the push plate. When the conveying motor drives the conveying roller to rotate to rotate the conveyor belt, the conveyor belt moves and drives the push plate to move. During the movement of the push plate, the push plate abuts against the limit plate, thereby forcing the moving platform and the parameter writing mechanism to follow the movement of the conveyor belt. At this time, the first elastic member undergoes elastic deformation, and the parameter writing mechanism corresponds to the position of the gas meter on the conveyor belt. The parameter writing mechanism performs parameter writing on the circuit board. After the circuit board parameters are written, the limit driving component drives the free end of the limit plate to swing upward, so that the limit plate is separated from the push plate, and the first elastic member forces the moving platform to retreat and reset. During the retreat of the moving platform, the limit driving component drives the free end of the limit plate to swing downward and reset, so that the free end of the limit plate is located on the moving path of the next push plate to perform the parameter writing operation of the next circuit board, and reciprocates in sequence. In the process of parameter writing for multiple batches of circuit boards, the conveying motor does not need to be frequently started and stopped, thereby improving the service life of the conveying motor.

[0007] Preferably, the moving platform is fixedly connected with an articulated seat, the articulated seat is rotatably connected with a limited articulated shaft, the axial direction of the limited articulated shaft is parallel to the conveying direction of the conveyor belt, the limited articulated shaft is fixedly sleeved with a limit swing arm, the limit plate is fixedly connected to one end of the limit swing arm, and the limit drive assembly includes an unlocking rod fixedly connected to an end of the limit swing arm away from the limit plate, a trigger block fixedly connected to the conveying frame and a second elastic member, the trigger block is located on the moving path of the unlocking rod, the trigger block has a function for the unlocking rod to abut to force the free end of the unlocking rod to swing so that the limit plate swings upward and separates from the guide surface of the push plate, and the second elastic member is arranged between the moving platform and the limit swing arm so that the free end of the unlocking rod swings and resets to a position corresponding to the trigger block.

[0008] By adopting the above technical solution, under normal conditions, the free end of the limit plate swings downward so that the free end of the limit plate is located on the moving path of the push plate, and the unlocking rod is in a vertical state, and the trigger block is located on the moving path of the unlocking rod. During the movement of the push plate, the push plate abuts against the limit plate, thereby forcing the moving platform and the parameter writing mechanism to move with the conveyor belt. At this time, the first elastic member undergoes elastic deformation and has elastic potential energy, and the parameter writing mechanism corresponds to the position of the gas meter on the conveyor belt. The parameter writing mechanism performs parameter writing on the circuit board. After the circuit board parameters are written, when the unlocking rod abuts against the guide surface of the trigger block, and the moving platform continues to move forward During the advancement, the guide surface of the trigger block forces the free end of the unlocking rod to swing outward and downward around the axis of the limit hinge shaft, thereby driving the limit plate to swing upward around the axis of the limit hinge shaft through the limit swing arm to separate the limit plate from the push plate. During this process, the second elastic member undergoes elastic deformation and has elastic potential energy. After the limit plate and the push plate are separated, the first elastic member immediately forces the moving platform to retreat and reset. After the moving platform retreats to separate the unlocking rod from the trigger block, the second elastic member immediately forces the limit swing arm to swing and reset, so that the free end of the limit plate is located on the moving path of the next push plate to perform the parameter writing operation of the next circuit board.

[0009] Preferably, the moving platform is fixedly connected with an articulated seat, the articulated seat is rotatably connected with a limited articulated shaft, the axial direction of the limited articulated shaft is parallel to the conveying direction of the conveyor belt, the limited articulated shaft is fixedly sleeved with a limit swing arm, the limit plate is fixedly connected to one end of the limit swing arm, the moving platform is fixedly connected with a guide transverse plate located above the limit plate, the upper end surface of the guide transverse plate close to the conveyor belt is provided with a first slide groove along the width direction of the conveyor belt, the plate surface of the push plate abutting against the limit plate is provided with a plug hole along the conveying direction of the conveyor belt, and the limit plate slides through a limit inserted in the plug hole The limit drive assembly includes a trigger block fixedly connected to the conveyor frame, a second elastic member arranged between the limit swing arm and the moving platform, an unlocking block slidably connected to the first slide groove, a connecting rope fixedly connected between the unlocking block and the limit plug rod, and a third elastic member arranged on the limit plate. The guide cross plate is located below the trigger block. The third elastic member normally forces the end of the limit plug rod to slide and protrude from the plate surface of the limit plate. The trigger block is normally located on the moving path of the unlocking block. The trigger block has a guide surface for the unlocking block to abut against to force the unlocking block to slide toward the outside.

[0010] By adopting the above technical solution, under normal conditions, the free end of the limit plate swings downward so that the free end of the limit plate is located on the moving path of the push plate, the trigger block is located on the moving path of the unlocking block, and the end of the limit plug rod slides and protrudes from the plate surface of the limit plate. During the movement of the push plate, the push plate abuts against the limit plate, and the limit plug rod is inserted in the insertion hole of the push plate, effectively preventing the limit plate from swinging and detaching during the limit plate process. The push plate pushes the moving platform and the parameter writing mechanism to follow the conveyor belt through the limit plate. At this time, the first elastic member undergoes elastic deformation and has elastic potential energy, and the parameter writing mechanism corresponds to the position of the gas meter on the conveyor belt. The parameter writing mechanism performs parameter writing on the circuit board. After the circuit board parameters are written, when the unlocking block abuts against the guide surface of the trigger block, and the moving platform continues to move forward During the sliding process, the guide surface of the trigger block forces the unlocking block to slide toward the side away from the conveyor belt. During the sliding process of the unlocking block, the limiting plug rod is first pulled by the connecting rope to slide, so that the limiting plug rod slides out of the socket of the push plate. After the fixation of the limiting plate is unlocked, the third elastic member is elastically deformed and has elastic potential energy. After the unlocking block continues to slide and the third elastic member reaches the elastic threshold, the limiting plate and the limiting swing arm are pulled by the connecting rope to swing upward around the limiting hinge axis, so that the limiting plate is separated from the push plate. In this process, the second elastic member is elastically deformed and has elastic potential energy. After the limiting plate and the push plate are separated, the first elastic member immediately forces the moving platform to retreat and reset. After the moving platform retreats to separate the unlocking block from the trigger block, the second elastic member immediately forces the limiting swing arm to swing and reset, and the third elastic member forces the limiting plug rod to slide and reset.

[0012] By adopting the above technical solution, the push plate abuts against the limit plate to force the movable platform and the parameter writing mechanism to move with the conveyor belt. At this time, the scanning piece corresponds to the label on the gas meter, and the data transmission piece is connected to the gas meter. The scanning piece scans and identifies the label on the gas meter. The industrial computer matches the circuit board parameters of the corresponding model and specifications according to the scanning information, and transmits the data through the data transmission piece to realize the writing of parameters.

[0013] Preferably, the support frame is vertically slidably connected to a lifting plate located above the gas meter, the support frame is provided with a lifting drive component for driving the lifting plate to rise and fall, the lifting plate is slidably connected to a correcting plate along the conveying direction of the conveyor belt, two correcting plates are provided and are spaced apart along the conveying direction of the conveyor belt, the two correcting plates are respectively abutted against the outer walls on both sides of the gas meter, and the lifting plate is provided with a correcting drive component for driving the correcting plate to slide.

[0014] By adopting the above technical scheme, under normal conditions, the deflection correction driving member drives the two deflection correction plates to slide in a direction away from each other so that the spacing between the two deflection correction plates is greater than the length of the gas meter, and the lifting driving member drives the lifting plate to move up so that the lower end surface of the deflection correction plate is located above the gas meter, thereby avoiding interference between the deflection correction plate and the gas meter. When the push plate abuts against the limit plate, the lifting driving member drives the lifting plate to move downward so that the two deflection correction plates are respectively located on both sides of the gas meter, and the two deflection correction plates are driven by the deflection correction driving member to slide in a direction close to each other so that the two deflection correction plates are respectively abutted against the outer walls of the two sides of the gas meter, thereby realizing the deflection correction, calibration and positioning of the gas meter, facilitating the connection of the data transmission component, and making the scanned component correspond to the label on the gas meter, thereby improving the success rate of parameter writing.

[0016] By adopting the above technical scheme, after the push plate abuts against the limit plate, the lifting drive member drives the lifting plate to move downward, and the spacing between the supporting cross plate and the lifting plate increases. The two sliders are pulled toward each other by the linkage rod, thereby driving the two correcting plates to slide toward each other so that the two correcting plates respectively abut against the outer walls on both sides of the gas meter, thereby realizing the correction and calibration positioning of the gas meter. When the parameter writing is completed, the lifting drive member drives the lifting plate to move up and reset, and the spacing between the supporting cross plate and the lifting plate increases. The two sliders are pushed toward each other by the linkage rod, thereby driving the two correcting plates to slide toward each other.

[0017] Preferably, the lifting plate is provided with a cleaning mechanism for cleaning the label surface / scanning piece on the gas meter.

[0018] By adopting the above technical solution and adding a cleaning mechanism, the possibility of dust interfering with the scanned document is reduced, thereby improving the success rate of the scanned document in scanning and identifying the label on the gas meter.

[0019] Preferably, the cleaning mechanism includes a cleaning support rod arranged on the lifting plate, an air blowing pipe arranged on the cleaning support rod, and an air supply assembly for supplying air to the air blowing pipe, the axial direction of the air blowing pipe is parallel to the conveying direction of the conveyor belt, the air blowing pipe is located between the scanning piece and the gas meter, and the outer peripheral wall of the air blowing pipe is provided with air holes for blowing and cleaning the label surface / scanning piece on the gas meter. During the parameter writing process, the air blowing pipe is located below the label.

[0020] By adopting the above technical solution, the lifting plate drives the cleaning support rod and the air blowing pipe to descend during the downward movement, and the air supply assembly supplies air to the air blowing pipe. The gas passes through the inner cavity of the air blowing pipe and is blown out through the air hole. When the air blowing pipe passes through the label and the scanned piece, the outer surface of the label and the optical components of the scanned piece are blown and cleaned, effectively reducing the possibility of dust adhering to the outer surface of the label and the outer surface of the optical components of the scanned piece. After the correction plate corrects the deviation, calibrates and positions the gas meter, the air blowing pipe is located below the label, reducing the possibility of the air blowing pipe obstructing and interfering with the scanning and recognition operation of the scanned piece.

[0021] Preferably, the air supply assembly includes an air supply box fixedly connected to the lifting plate, a piston plate sealingly and slidably connected to the inner cavity of the air supply box, a movable rod slidably penetrated through the end surface of the air supply box, and an air supply pipe connected to the inner cavity of the air supply box and the inner cavity of the air blowing pipe, two piston plates and two movable rods are provided, the air supply box is located between the two sliders, there is a gap between the movable rod and the end wall of the air supply box, one end of the movable rod is fixedly connected to the slider, and the other end of the movable rod is fixedly connected to the piston plate, and the connecting port of the air supply pipe and the air supply box is located between the two piston plates.

[0022] By adopting the above technical scheme, during the downward movement of the lifting plate, the two sliders are pulled by the linkage rod to slide in the direction of approaching each other, thereby driving the two correcting plates to slide in the direction of approaching each other so that the two correcting plates are respectively abutted against the outer walls of the two sides of the gas meter, thereby realizing the correction, calibration and positioning of the gas meter. During the sliding of the two sliders in the direction of approaching each other, the two piston plates are pushed by the movable rod to slide in the direction of approaching each other, so that the volume of the air cavity between the two piston plates becomes smaller, so that the gas between the two piston plates enters the air blowing pipe through the air supply pipe and is blown out from the air blowing hole of the air blowing pipe, and the outer surface of the label and the optical components of the scanned piece are blown and cleaned. When the parameter writing is completed, during the upward resetting process of the lifting plate, the two sliders slide in the direction of moving away from each other, and the two piston plates are pulled by the movable rod to slide in the direction of moving away from each other, so that the volume of the air cavity between the two piston plates is increased, and the air cavity between the two piston plates is in a negative pressure state, and the external gas enters the air blowing pipe, the air supply pipe and the air cavity between the two piston plates in sequence through the air blowing hole.

[0023] Preferably, the air blowing pipe is connected to the cleaning support rod by rotating around its own axis, a plurality of air blowing holes are provided and distributed circumferentially around the air blowing pipe, and the cleaning support rod is provided with a rotating component for driving the air blowing pipe to rotate.

[0024] By adopting the above technical solution, the air blowing pipe is rotatably connected to the cleaning support rod. When the lifting plate moves downward, the air blowing pipe keeps rotating to change the position of the air blowing hole, so that the air flow blown out of the air blowing hole forms a rotary cutting airflow, thereby improving the air blowing cleaning effect on labels and scanned parts.

[0026] 1. Under normal conditions, the free end of the limit plate swings downward so that the free end of the limit plate is located on the moving path of the push plate. When the conveying motor drives the conveying roller to rotate so that the conveyor belt rotates, the conveyor belt moves and drives the push plate to move. During the movement of the push plate, the push plate abuts against the limit plate, thereby forcing the moving platform and the parameter writing mechanism to follow the movement of the conveyor belt. At this time, the first elastic member undergoes elastic deformation, and the parameter writing mechanism corresponds to the position of the gas meter on the conveyor belt. The parameter writing mechanism performs parameter writing on the circuit board. After the circuit board parameters are written, the limit driving component drives the free end of the limit plate to swing upward, so that the limit plate is separated from the push plate, and the first elastic member forces the moving platform to retreat and reset. During the retreat of the moving platform, the limit driving component drives the free end of the limit plate to swing downward and reset, so that the free end of the limit plate is located on the moving path of the next push plate to perform the parameter writing operation of the next circuit board, and reciprocates in sequence.

In other embodiments, the deflection correction driving member can independently drive the deflection correction plate 38 to slide through a cylinder.

[0050] In the embodiment, manipulators are provided at both ends of the conveyor belt 2, and the gas meter 10 is grabbed by the manipulators to achieve loading / unloading.

[0051] The implementation principle of the embodiment of the present application is as follows: under normal conditions, the limit swing arm 133 is in a horizontal state, so that the free end of the limit plate 16 is located on the moving path of the push plate 21, and the unlocking rod 41 is in a vertical state, and the trigger block 43 is located on the moving path of the unlocking rod 41. During the process of the conveyor belt 2 conveying the gas meter 10, the push plate 21 abuts against the limit plate 16, thereby forcing the moving platform 13 to move with the conveyor belt 2. At this time, the first tension spring undergoes elastic deformation and has elastic potential energy. At the same time, the gas meter 10 is located below the lifting plate 35, and the piston rod of the lifting cylinder 36 extends to drive the lifting plate 35 to move downward, and the distance between the supporting cross plate 322 and the lifting plate 35 increases, and through The linkage rod 37 pulls the two sliders 351 to slide towards each other, thereby driving the two correcting plates 38 to slide towards each other so that the two correcting plates 38 respectively abut against the upper outer walls on both sides of the gas meter 10, thereby realizing the correction calibration and clamping of the gas meter 10, so that the scanned piece and the label 101 on the gas meter 10 correspond, and the data transmission hole 102 of the gas meter 10 and the plug connector of the data transmission line are aligned. Then, the piston rod of the horizontal cylinder 324 is extended to drive the movable seat 323 to slide towards the gas meter 10, so that the plug connector of the data transmission line is inserted into the data transmission hole 102, electrically connected to the circuit board and energized.

[0052] Parameter writing: The scanner scans and identifies the label 101 on the gas meter 10, and the industrial computer 31 matches the circuit board parameters of the corresponding model and specifications according to the scan information, and writes the parameters to the circuit board through the data transmission line. When the parameter writing is completed, the piston rods of the horizontal cylinder 324 and the lifting cylinder 36 are retracted and reset, the plug connector of the data transmission line is pulled out, and the lower end surface of the correction plate 38 is located above the gas meter 10.

[0053] After the parameter writing is completed, the mobile platform continues to move forward. When the unlocking rod 41 abuts against the guide surface of the trigger block 43, and during the continuous movement of the mobile platform 13, the guide surface 431 of the trigger block 43 forces the free end of the unlocking rod 41 to swing outward and downward around the axis of the limit hinge shaft 132, thereby driving the limit plate 16 to swing upward around the axis of the limit hinge shaft 132 through the limit swing arm 133, so that the limit plate 16 is separated from the push plate 21. In this process, the second tension spring undergoes elastic deformation with elastic potential energy, and the limit plate After 16 and the push plate 21 are disengaged, the first tension spring immediately forces the moving platform 13 to retreat and reset. After the moving platform 13 retreats to separate the unlocking rod 41 from the trigger block 43, the second tension spring immediately forces the limit swing arm 133 to swing and reset, so that the limit plate 16 is located on the moving path of the next push plate 21 to perform the parameter writing operation of the next gas meter, and the process is repeated in sequence. In the process of writing parameters to multiple batches of gas meters, the conveying motor 12 does not need to be frequently started and stopped, thereby increasing the service life of the conveying motor 12.

[0056] When the lifting plate 35 moves downward, the distance between the supporting cross plate 322 and the lifting plate 35 increases, and the two sliders 351 are pulled toward each other through the linkage rod 37, thereby driving the two correcting plates 38 to slide toward each other so that the two correcting plates 38 are respectively in contact with the outer walls on both sides of the gas meter 10, thereby realizing the correction calibration and clamping of the gas meter 10, so that the scanning gun 33 and the label 101 on the gas meter 10 correspond, and the infrared transmitter and the infrared receiver on the circuit board are aligned. During the parameter writing process: the scanning gun 33 scans and identifies the label 101 on the gas meter 10, the industrial computer 31 matches the circuit board parameters of the corresponding model and specifications according to the scanning information, and transmits infrared rays through the external infrared receiver to transmit data, and the infrared receiver transmits the received data to the single-chip microcomputer of the circuit board, thereby realizing wireless writing of the circuit board parameters.
