Description

Technical Field

[0001] The invention relates to the technical field of vehicle control, and in particular to a Gagewood optical coupling fixed limit control device. Background Art

[0002] In the field of automation control, precise positioning and limit control are key technologies to ensure stable operation of equipment and prevent accidental damage. In particular, the role of the limit control board is particularly important in scenarios where precise control of the motion position is required, such as automated guided vehicles in three-dimensional warehousing and mobile platforms on automated production lines. Traditional limit control methods mostly use mechanical contacts or electronic sensors to achieve position detection and feedback, but these methods often have problems such as insufficient accuracy, low reliability or high cost.

[0003] Especially in applications such as lift trucks, due to space limitations and complex working environments, traditional limit control methods often fail to meet the requirements of high precision, high reliability and low cost. For example, mechanical contact limit switches are prone to poor contact due to wear and contamination, affecting positioning accuracy; while electronic sensors have high precision, they are also relatively expensive and may not work properly in certain extreme environments.

[0004] Traditional lift positioning systems usually rely on the encoder of the lift motor or the communication signal controlled by the microcontroller to achieve real-time feedback and adjustment of the position. However, this positioning method that relies on electronic signals may face challenges under certain conditions. When the encoder of the lift motor fails or a single failure such as the motor drive occurs, the accuracy of the positioning system will be greatly reduced, which may cause the lift to deviate from the predetermined path or even run beyond the limit position, thereby increasing the risk of damage to the body parts. This situation will not only cause downtime and maintenance costs for the equipment, but may also cause serious safety accidents.

[0005] The disclosure of the above background technology content is only used to assist in understanding the inventive concept and technical solution of the present invention. It does not necessarily belong to the prior art of this patent application, nor does it necessarily provide technical guidance. In the absence of clear evidence that the above content has been disclosed before the filing date of this patent application, the above background technology should not be used to evaluate the novelty and creativity of the present application. Summary of the invention

[0006] In order to solve the technical problems such as positioning errors caused by single faults of detection elements such as motor encoders or motor drives, and the inability to provide additional safety guarantees at the hardware level, resulting in the lift truck not running in place or exceeding the limit position, thereby causing equipment damage, the present invention proposes a Gegewu optical coupling fixed limit control device.

[0009] Wherein, in the height direction of the movable block, the position of the first block is higher than the position of the second block, so that when the movable block moves along the predetermined path, the first block can block the corresponding optical coupler before the second block.

[0010] The present invention proposes a Gegewu optical coupling fixed limit control device. This design can not only effectively avoid positioning errors caused by motor encoder detection or motor drive abnormalities, but also provide additional safety guarantees at the hardware level to prevent the lift from running out of position or exceeding the limit position, thereby greatly reducing equipment damage and safety risks. At the same time, the design has the significant advantages of low cost, high reliability and small space occupation, and can be used in automatic guided vehicles with narrow spaces.

[0011] As a preferred technical solution, the optocoupler includes: an upper limit optocoupler, a lower limit optocoupler, an upper positioning optocoupler and a lower positioning optocoupler. The upper limit optocoupler and the upper positioning optocoupler are connected to an edge position of the optocoupler board, and the lower limit optocoupler and the lower positioning optocoupler are connected to another corresponding edge position of the optocoupler board.

[0012] As a preferred technical solution, the optical coupler includes: a zero position optical coupler, the zero position optical coupler is used to determine a reference or starting position, and the zero position optical coupler is connected to the middle position of the optical coupling plate.

[0013] As a preferred technical solution, it includes: a servo motor, and the servo motor is connected to the movable stopper.

[0014] As a preferred technical solution, it includes: a single chip microcomputer, an encoder is provided on the servo motor, the encoder is electrically connected to the single chip microcomputer, and the single chip microcomputer is electrically connected to the movable block to control the movable block to move to the position corresponding to the optical coupler.

[0015] As a preferred technical solution, the upper positioning optocoupler and the lower positioning optocoupler are used to detect whether the movable block reaches a predetermined positioning position. The upper positioning optocoupler and the lower positioning optocoupler are electrically connected to the single-chip microcomputer, and the single-chip microcomputer is electrically connected to the servo motor to control the working state of the servo motor.

[0016] As a preferred technical solution, the position of the upper positioning optical coupler, the position of the zero position optical coupler and the position of the lower positioning optical coupler form a clear oblique line on the optical coupling plate;

[0017] The position of the upper position optical coupler, the position of the zero position optical coupler and the position of the lower position optical coupler form another clear oblique line on the optical coupling plate.

[0018] As a preferred technical solution, the upper limit optical coupler, the lower limit optical coupler, the upper positioning optical coupler, the lower positioning optical coupler and the zero position optical coupler are all provided with blocking grooves, and the blocking grooves are used for the first baffle or the second baffle to block the limit setting.

[0020] The other end of the second blocking piece extends to the other end of the blocking block body through an arc-shaped member, and the other end of the blocking block body extends to the other end of the first blocking piece.

[0021] As a preferred technical solution, the main viewing surface of the movable stopper is in an "S" shape.

[0022] The present invention provides a Gegewu optical coupling limit control device, which has the following beneficial effects:

[0023] 1) This design can not only effectively avoid positioning errors caused by motor encoder detection or motor drive abnormalities, but also provide additional safety protection at the hardware level to prevent the lift truck from running out of position or exceeding the limit position, thereby greatly reducing equipment damage and safety risks. At the same time, this design has the significant advantages of low cost, high reliability and small footprint, and can be used in automatic guided vehicles with narrow spaces;

[0024] 2) In the technical solution, a plurality of optical couplers are arranged on the optical coupling board, and the optical couplers are arranged along a predetermined path to detect the position of the block. The block is composed of a first block and a second block, and the two blocks are different in height direction, so that when the block moves, the first block can block the corresponding optical coupler before the second block;

[0025] When the block moves along a predetermined path, the first baffle and the second baffle on it will sequentially block the optical coupler on the path. Since the position of the first baffle is higher than that of the second baffle, when the movable block moves to a certain position, the first baffle will first block the corresponding positioning optical coupler and send out a signal indicating that the block has reached the position. At this time, the single-chip microcomputer will control the servo motor to stop working. If the single-chip microcomputer communication fails or the encoder of the servo motor fails, the movable block will continue to move upward until the second baffle also blocks its corresponding limit optical coupler. At this time, the servo motor will stop working through hardware to prevent the lift from running beyond the limit position and causing equipment damage or safety risks.

[0026] Optocoupler is a photoelectric device. Its working principle is to use light as a medium to transmit electrical signals. The input electrical signal drives the light-emitting diode (LED) to emit light of a certain wavelength. The light is received by the photosensitive element (such as a phototransistor) and converted into an electrical signal output, thereby realizing the electrical-optical-electrical conversion process. This conversion process makes the optocoupler have the characteristics of electrical isolation and strong anti-interference ability. The optocoupler can maintain a stable working state and provide accurate feedback signals.

[0027] In addition, due to the physical contact characteristics of the block and the optocoupler, this technical solution can also provide additional safety protection at the hardware level. Even if the control system fails or misjudges, the physical shielding effect of the block can prevent the lift from running beyond the limit position. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] like Figure 1-4 As shown, the present invention provides a Gegewu optical coupling fixed limit control device, comprising: an optical coupling plate 1, on which a movable block 2 and a plurality of optical couplers 3 are provided, the movable block 2 has a first block 4 and a second block 5, the first block 4 and the second block 5 are respectively used to block the plurality of optical couplers 3 arranged on a predetermined path, so as to realize feedback of a plurality of different positions;

[0035] Among them, in the height direction of the movable block 2, the position of the first block 4 is higher than the position of the second block 5, so that when the movable block 2 moves along the predetermined path, the first block 4 can block the corresponding optical coupler 3 before the second block 5.

[0036] The present invention proposes a Gegewu optical coupling fixed limit control device. This design can not only effectively avoid positioning errors caused by motor encoder detection or motor drive abnormalities, but also provide additional safety guarantees at the hardware level to prevent the lift from running out of position or exceeding the limit position, thereby greatly reducing equipment damage and safety risks. At the same time, the design has the significant advantages of low cost, high reliability and small space occupation, and can be used in automatic guided vehicles with narrow spaces.

[0037] Preferably, if Figure 1-4 As shown, the optical coupler includes: an upper limit optical coupler 6, a lower limit optical coupler 7, an upper positioning optical coupler 8 and a lower positioning optical coupler 9.

The upper limit optical coupler 6, the lower limit optical coupler 7, the upper positioning optical coupler 8 and the lower positioning optical coupler 9 are used in combination to achieve precise control of the movement range of the lifting vehicle, which helps to improve the stability and safety of the system and reduce damage and safety risks to the equipment.

[0038] Preferably, if Figure 1-4As shown, the optical coupler includes: a zero position optical coupler 10, the zero position optical coupler 10 is used to determine the reference or starting position, and the zero position optical coupler 10 is connected to the middle position of the optical coupling plate 1; the main function of the zero position optical coupler 10 is to provide a clear reference or starting position. When the lifting vehicle or related moving parts are started or reset for the first time, the movable block 2 will first block the zero position optical coupler 10. This action will trigger the control system to set the position of the encoder of the servo motor (not shown) to zero, so that it can recognize the current position as the reference position or starting point, thereby ensuring the motion trajectory and positioning accuracy of the lifting vehicle.

[0039] Preferably, if Figure 1-4 As shown, it includes: a servo motor (not shown) and a single-chip microcomputer (not shown), the servo motor (not shown) is connected to the movable block 2, the servo motor (not shown) is provided with an encoder (not shown), the encoder (not shown) is electrically connected to the single-chip microcomputer (not shown), the single-chip microcomputer (not shown) is electrically connected to the movable block 2 to control the movable block 2 to move to the position corresponding to the optical coupler 3; the upper positioning optical coupler 8 and the lower positioning optical coupler 9 are used to detect whether the movable block 2 reaches a predetermined positioning position, the upper positioning optical coupler 8 and the lower positioning optical coupler 9 are electrically connected to the single-chip microcomputer (not shown), the single-chip microcomputer (not shown) is electrically connected to the servo motor (not shown) to control the working state of the servo motor (not shown);

[0040] The single chip microcomputer (not shown) adjusts the movement of the servo motor (not shown) in real time according to the route length information preset by the encoder (not shown) to move to different optical couplers. The servo motor receives the control instruction and drives the movable block 2 to move according to the predetermined motion trajectory calculated according to the route length of the optical coupler 3, ensuring that the movable block 2 can accurately move to the target position of different optical couplers 3.

[0041] In the process of the movable block 2 moving from the zero position optical coupler 10 to the upper positioning optical coupler 8 according to the predetermined motion trajectory, when the first baffle 4 of the movable block 2 blocks the upper positioning optical coupler 8, it will trigger the upper positioning optical coupler 8 to send an electrical signal, and the single chip microcomputer (not shown) receives the signal sent by the upper positioning optical coupler 8 to determine whether the movable block 2 has reached the predetermined positioning position. When the upper positioning optical coupler 8 detects that the movable block 2 has reached the predetermined upper positioning position, the single chip microcomputer (not shown) will issue an instruction to enable the servo motor (not shown) to perform the next step of operation; when the first baffle 4 of the movable block 2 blocks the upper positioning optical coupler 8, the upper positioning optical coupler 8 will be triggered to send an electrical signal, and the single chip microcomputer (not shown) will receive the signal sent by the upper positioning optical coupler 8 to determine whether the movable block 2 has reached the predetermined positioning position. When the upper positioning optical coupler 8 detects that the movable block 2 has reached the predetermined upper positioning position, the single chip microcomputer (not shown) will issue an instruction to enable the servo motor (not shown) to perform the next step of operation; when the first baffle 4 of the movable block 2 4. The upper positioning optical coupler 8 is not blocked, which triggers the upper positioning optical coupler 8 to send an electrical signal. The single chip microcomputer (not shown) receives the signal sent by the upper positioning optical coupler 8 and determines whether the movable block 2 has reached the predetermined positioning position. When the upper positioning optical coupler 8 detects that the movable block 2 has not reached the predetermined upper positioning position and fails to detect that it is not in place, the single chip microcomputer (not shown) will issue an instruction to refuse the device to continue to operate, the servo motor (not shown) stops working, and the Gegewu optical coupler limit control device stops working to prevent the lifting vehicle from running out of place, thereby greatly reducing equipment damage and safety risks;

[0042] In the process of the movable block 2 moving from the upper positioning optical coupler 8 to the lower positioning optical coupler 9 according to the predetermined motion trajectory, when the second baffle 5 of the movable block 2 blocks the lower positioning optical coupler 9, the lower positioning optical coupler 9 will be triggered to send an electrical signal, and the single-chip microcomputer (not shown) receives the signal sent by the lower positioning optical coupler 9 to determine whether the movable block 2 has reached the predetermined positioning position. When the lower positioning optical coupler 9 detects that the movable block 2 has reached the predetermined lower positioning position, the second baffle 5 of the movable block 2 blocks the lower positioning optical coupler 9, and the single-chip microcomputer (not shown) will issue a command to make the servo motor (not shown) perform the next step of operation; when the movable block 2 moves from the upper positioning optical coupler 8 to the lower positioning optical coupler 9 ... single-chip microcomputer (not shown) will issue a command to make the servo motor (not shown) perform the next step of operation; when the movable block 2 moves from the upper positioning optical coupler 8 to the lower positioning optical coupler 9, the single-chip microcomputer (not shown) will issue a command to make the servo motor (not shown) perform the next step of operation; when the movable block 2 moves from the upper positioning optical coupler 8 to the lower positioning optical coupler 9, the single-chip microcomputer (not shown) will issue a The second baffle 5 of the movable block 2 does not block the lower positioning optical coupler 9, which triggers the lower positioning optical coupler 9 to send an electrical signal. The single chip microcomputer (not shown) receives the signal sent by the lower positioning optical coupler 9 and determines whether the movable block 2 has reached the predetermined positioning position. When the lower positioning optical coupler 9 detects that the movable block 2 has not reached the predetermined lower positioning position and fails to detect the position, the single chip microcomputer (not shown) will issue an instruction to refuse the device to continue running, the servo motor (not shown) stops working, and the Gegewu optical coupler limit control device stops working, so as to prevent the problem of the lifting vehicle not running in place, thereby greatly reducing equipment damage and safety risks;

[0043] When the movable block 2 triggers the upper positioning optical coupler 8, if the encoder (not shown) detection or the servo motor (not shown) driving abnormality causes a positioning error, the movable block 2 will continue to move upward until the second baffle 5 also blocks its corresponding upper limit optical coupler 6, at which time the servo motor will stop working through hardware; when the movable block 2 triggers the lower positioning optical coupler 9, if the encoder (not shown) detection or the servo motor (not shown) driving abnormality causes a positioning error, the movable block 2 will continue to move downward until the first baffle 4 also blocks its corresponding lower limit optical coupler 7, at which time the servo motor (not shown) will stop working through hardware to prevent the lifting vehicle from running beyond the limit position, thereby greatly reducing equipment damage and safety risks.
