Description

Technical Field

[0001] The present invention relates to the field of wireless radio frequency identification technology, and in particular to an RFID antenna fixing device for physical seal management and control equipment. Background Art

[0002] In daily management work, in order to improve the efficiency and quality of printing, automatic printing machines are used to print documents. Generally, different seals are required for different document materials. This requires the automatic printing machine to not only realize basic printing operations, but also to realize the conversion between different seals according to different needs. The existing technology basically adopts the traditional motor to rotate and drive the seal turntable to realize the seal changing operation. When the printing task volume is large, the seal conversion time required by the conversion mechanism is long, which affects the operating efficiency of the automatic printing machine. Using a robotic arm to grab the corresponding seal tube for printing can solve the problem of the disc-type seal changing. However, the robotic arm extracting the corresponding seal tube for printing involves grabbing the seal tube and moving the seal tube to the corresponding position of the seal storage. The moving position needs to be accurate and error-free so that the robotic arm can extract the seal tube next time. Therefore, there is an urgent need for a technology to solve the problem of inaccurate control of the placement of multiple seals in the seal control equipment. Summary of the Invention

[0049] The central control unit is located in the shell and is connected to the RFID unit and the printing unit respectively, and is used to determine whether the chapter tube has reached the corresponding position of the chapter library rack based on the data pushed by the RFID unit and, when it is determined that the chapter tube has not reached the corresponding position, adjust the running time of the robotic arm and the tension of the conveyor belt to corresponding values ​​based on the running speed, running trajectory and motor speed of the robotic arm to move the chapter tube to the corresponding position of the chapter library rack.

[0050] The present invention is provided with a shell, a printing unit, an RFID unit and a central control unit; the central control unit forms a signal response end and a signal processing end by the RFID tag on the side wall of the seal tube in the RFID unit and the RFID antenna and the RFID reader / writer arranged at the corresponding position of the seal library rack. The central control unit determines whether the seal tube has reached the corresponding position according to the strength of the signal and detects the relevant data for not reaching the corresponding position, which can avoid the problem that the seal tube has not moved to the corresponding position and affects the failure of the next mechanical arm to extract the corresponding seal tube, and can make targeted and precise adjustments to the situation where the seal tube has not reached the corresponding position, thereby improving the precise control of each seal and further improving the operating efficiency of the present invention for the documents to be printed.

[0051] Specifically, when the RFID reader / writer identifies the signal of the RFID tag corresponding to the back plate of each chapter tube through the RFID antenna, the central control unit extracts the signal data, marks each signal data and determines whether the corresponding chapter tube has returned to the corresponding position of the chapter rack.

[0052] After the RFID reader / writer of the present invention recognizes the signal of the RFID tag corresponding to the back plate of each chapter tube through the RFID antenna, the central control unit can mark the signal of each chapter tube, thereby avoiding signal confusion when recognizing multiple chapter tubes, improving the signal recognition accuracy between the RFID reader / writer and the RFID tag of each chapter tube, and further improving the accuracy of the central control unit in calculating the distance between the RFID reader / writer and the RFID tag of each chapter tube.

[0053] Specifically, the central control unit is provided with a preset standard distance S0 between the RFID reader and the RFID tag; when the robotic arm completes the use of the seal and moves the single chapter tube to the corresponding chapter rack, the signal processing end attempts to receive the signal from the signal response end to detect whether the RFID tag in the chapter tube is in the specified position. If the central control unit issues an alarm that the chapter tube has not returned to its position, the central control unit controls the distance measuring device to detect the distance S between the RFID tag and the RFID reader.

[0054] If S≤S0, the central control unit determines that the RFID tag is damaged or the RFID reader is faulty, and the central control unit issues a fault alarm;

[0055] If S>S0, the central control unit determines that the robotic arm has not moved the chapter tube to the corresponding position of the chapter rack. The central control unit controls the signal processing end to delay the detection of whether the robotic arm has moved the chapter tube to the corresponding position of the chapter rack. The central control unit calculates the difference △S between S and S0 to adjust the operating time of the robotic arm to the corresponding value, and sets △S=S-S0.

[0056] Specifically, the central control unit is provided with a first preset distance difference △S1, a second preset distance difference △S2, a first preset robot arm operation time adjustment coefficient α1, and a second preset robot arm operation time adjustment coefficient α2, wherein △S1<△S2, 1<α1<α2; when the central control unit determines that the robot arm has not moved the chapter tube to the corresponding position of the chapter library rack, the central control unit calculates the difference △S between S and S0 to determine the robot arm operation time,

[0057] If ΔS≤ΔS1, the central control unit determines that the chapter tube is close to the corresponding position of the chapter tube on the chapter rack, and the central control unit uses α1 to adjust the operating time of the robotic arm;

[0058] If ΔS1<ΔS≤ΔS2, the central control unit determines that the chapter tube is close to the corresponding position of the chapter tube on the chapter rack, and the central control unit uses α2 to adjust the operating time of the robotic arm;

[0059] If ΔS>ΔS2, the central control unit determines that the chapter tube is far away from the corresponding position of the chapter tube on the chapter rack, and the central control unit detects the running speed V of the robot arm to determine whether the running speed of the robot arm reaches a preset value;

[0060] When the central control unit determines to use αi to adjust t, set i=1,2; the time the robotic arm runs again is recorded as △t, and set △t=t×(αi-1); the central control unit will compare the total operating time of the determined robotic arm with the maximum total operating time of the preset robotic arm to confirm the total operating time of the robotic arm.

[0061] Specifically, the central control unit is provided with a preset maximum total operation time tmax of the robot arm. When the central control unit adjusts the total operation time t' of the robot arm after the adjustment is completed, where t'=t×αi,

[0062] If t'>tmax, the central control unit determines that the total operating time of the robotic arm is tmax;

[0063] If t'≤Δtmax, the central control unit determines that the total operating time of the robotic arm is t'.

[0064] The present invention determines the distance between the seal rack and the seal tube by the central control unit to confirm whether to move the seal tube to the corresponding position of the seal rack. For the seal tube that has not reached the corresponding position, the central control unit calculates the difference between the actual distance and the preset distance, preliminarily determines the reason why the sliding sleeve has not reached the corresponding position, adjusts the operating time of the robot arm, and determines the adjusted time, thereby improving the efficiency of the robot arm in transporting the seal tube and further improving the precise control of each seal.

[0065] Specifically, the central control unit detects the motor speed of the robot arm and calculates the running speed V0 of the conveyor belt and the actual running speed V of the robot arm according to the motor speed.

[0066] If V<V0, the central control unit determines that the friction of the conveyor belt driven by the robotic arm is small during operation, and the central control unit detects the running trajectory of the robotic arm to determine the axial direction of the conveyor belt where the friction is small;

[0067] If V=V0, the central control unit determines that the operating speed of the robotic arm is the standard value, and the central control unit issues a robotic arm failure alarm.

[0068] The present invention detects the running speed of the robot arm through the central control unit to make a preliminary judgment on whether the friction of the conveyor belt driven by the robot arm motor is small during the rotation process. It can accurately determine the reason for the low running speed of the robot arm, thereby improving the operating efficiency of the robot arm during the operation process.

[0069] Specifically, the central control unit is provided with a total transverse distance Ba and a total longitudinal distance Bb of the robot arm; when the central control unit determines that the friction force of the conveyor belt of the robot arm is small during operation, the central control unit counts the transverse running distance Ba' and the longitudinal running distance Bb' of the robot arm to determine the conveyor belt axis with small friction force.

[0070] If Ba'<Ba, the central control unit determines that the friction of the transverse conveyor belt is small, and the central control unit calculates the ratio of the transverse running distance of the robot arm to the total transverse distance and uses the corresponding adjustment coefficient to adjust the tension of the transverse conveyor belt;

[0071] If Bb'<Bb, the central control unit determines that the friction of the longitudinal conveyor belt is small, and the central control unit calculates the ratio of the longitudinal running distance of the robot arm to the total longitudinal distance and uses the corresponding adjustment coefficient to adjust the tension of the longitudinal conveyor belt;

[0072] If Ba'=Ba and Bb'=Bb, the central control unit determines that the transverse and longitudinal conveyor belts are operating normally, and the central control unit determines that the robotic arm has a fault and issues a fault alarm;

[0073] If Ba'>Ba, the central control unit determines the conveyor belt motor, and the central control unit replans the running path of the robot arm and corrects the motor speed R of the conveyor belt running horizontally;

[0074] If Bb'>Bb, the central control unit determines that the conveyor belt motor speed failure occurs, and the central control unit replans the operation path of the robot arm and corrects the motor speed R of the conveyor belt running in the longitudinal direction.

[0075] Specifically, the central control unit is provided with a first conveyor belt tension adjustment coefficient γ1 and a second conveyor belt tension adjustment coefficient γ2, wherein 1<γ1<γ2; the central control unit determines whether the friction force of the transverse conveyor belt or the longitudinal conveyor belt is small during operation.

[0076] If Ba' / Ba>1 / 4, the central control unit determines to use γ1 to adjust the tension Z of the tension wheel of the transverse conveyor belt;

[0077] If Bb' / Bb>1 / 4, the central control unit determines to use γ1 to adjust the tension Z of the tensioning wheel of the longitudinal conveyor belt;

[0078] If 1 / 4<Ba' / Ba≤1 / 3, the central control unit determines to use γ2 to adjust the tension Z of the tensioning wheel of the transverse conveyor belt;

[0079] If 1 / 4<Bb' / Bb≤1 / 3, the central control unit determines to use γ2 to adjust the tension Z of the tensioning wheel of the longitudinal conveyor belt;

[0080] If Ba' / Ba>1 / 3, the central control unit determines that the transverse conveyor belt is aging and issues a prompt to replace the transverse conveyor belt;

[0081] Or Bb' / Bb>1 / 3, the central control unit determines that the longitudinal conveyor belt is aging and issues a prompt to replace the longitudinal conveyor belt;

[0082] When the central control unit determines to use γk to adjust the tension Z, k is set to 1, 2; the adjusted tension is recorded as Z', and Z' is set to Z×γk; after adjusting the tension of the corresponding conveyor belt, the central control unit controls the robot arm to move the corresponding chapter tube again and re-identify it through the RFID unit, and the central control unit determines whether the chapter tube has moved to the corresponding position of the chapter rack.

[0083] The present invention uses the central control unit to make a preliminary judgment on the movement trajectory of the robotic arm of the sliding sleeve that has not reached the corresponding position to determine whether the horizontal or vertical conveyor belt friction is small, and determines the adjustment coefficient of the conveyor belt tensioning wheel tensioning according to the ratio of the movement distance of the robotic arm to the horizontal and vertical distances, and adjusts it. It can automatically and accurately adjust the friction of the conveyor belt to be small when the conveyor belt is running, which can improve the repair efficiency of the robotic arm when it fails, and further improve the operating efficiency of the robotic arm during operation.

[0084] Specifically, the central control unit is provided with the standard motor speed R1 of the manipulator when it is running horizontally, the standard motor speed R2 of the manipulator when it is running vertically, the first speed difference △R1, the first speed difference △R2, the first transfer speed adjustment coefficient β1 and the first transfer speed adjustment coefficient β2, wherein △R1 < △R2, β1 < β2 < 1; when the central control unit determines that the horizontal or vertical conveyor belt motor has a fault, the central control unit detects the motor speed Rx of the manipulator when it is running horizontally and the motor speed Ry in the vertical direction,

[0085] If Rx is less than R1, the central control unit determines that the motor of the robotic arm is faulty and issues a fault alarm to prompt the staff to repair it;

[0086] If Rx>R1, the central control unit determines that the motor speed of the manipulator arm is too fast, and the central control unit calculates the difference △R between Rx and R1; if △R≤△R1, the central control unit determines to use β1 to adjust Rx to the corresponding value; if △R1≤△R≤△R2, the central control unit determines to use β2 to adjust Rx to the corresponding value; if △R>△R2, the central control unit determines that the motor of the manipulator arm is faulty and issues a fault alarm to prompt the staff to repair it;

[0087] If Ry<R2, the central control unit determines that the motor of the robotic arm is faulty and issues a fault alarm to prompt the staff to repair it;

[0088] If Ry>R2, the central control unit determines that the motor speed of the manipulator arm is too fast, and the central control unit calculates the difference △R' between Ry and R2; if △R'≤△R1, the central control unit determines to use β1 to adjust Ry to the corresponding value; if △R1≤△R'≤△R2, the central control unit determines to use β2 to adjust Ry to the corresponding value; if △R'>△R2, the central control unit determines that the motor of the manipulator arm is faulty and issues a fault alarm to prompt the staff to repair it;

[0089] When the central control unit determines to use βj to adjust the speed of the corresponding motor, j is set to 1, 2, the adjusted speed is recorded as r, and r is set to Ra×βj, where a=x, y. After the central control unit adjusts the corresponding motor speed, the central control unit controls the robot arm to move the corresponding chapter tube again and re-identify it through the RFID unit. The central control unit determines whether the chapter tube has moved to the corresponding position of the chapter rack.

[0090] The present invention detects the motor speed of the corresponding axis and adjusts the corresponding motor speed to the corresponding value according to the detection result. It can accurately adjust the situation where there is a problem with the operation path of the robot arm so that the robot arm can run the chapter tube to the corresponding position of the chapter library rack, and can accurately judge the problem with the motor.

The transverse conveyor belt and the longitudinal conveyor belt are also provided with corresponding axial tensioning wheels to adjust the friction of the conveyor belt accordingly.
