Description

Technical Field

[0001] The utility model belongs to the field of electrical technology and relates to a lifting mechanism control circuit board detection device, which is applied to the device for debugging and function detection of the lifting mechanism control circuit board during the assembly and adjustment process of batch production of photoelectric platform lifting systems. Background Art

[0002] The lifting mechanism control circuit board is the core component of the photoelectric platform lifting system. In the prior art, (1) during the electrical debugging of the lifting mechanism control circuit board, the circuit board is directly powered by a DC regulated power supply, and the circuit board detection points are measured manually using a multimeter. Due to the small detection space and dense pins, the positive and negative test leads are easy to short-circuit when measuring the voltage signal, causing the circuit board to work abnormally, and even damaging the circuit board in severe cases. Therefore, this debugging method has the risk of inaccurate measurement results, low test efficiency, and even damage to the circuit board; (2) For the functional detection of the lifting mechanism control circuit board, it can only be tested in the whole system after the lifting system is assembled. If the circuit board function is abnormal, it will cause the motor to lose control, the limit does not work, and other problems, affecting the service life of the motor and causing damage to the structural components of the whole system. This detection method is time-consuming and labor-intensive, and seriously affects the mass production efficiency and delivery progress of the photoelectric platform lifting system.

[0039] In order to make the purpose, content and advantages of the utility model clearer, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments.

[0040] This embodiment provides a lifting mechanism controlled circuit board detection device, such as Figure 1-Figure 5 As shown, the lifting mechanism control circuit board detection device includes a device housing 11, a power supply circuit 12, a motor enable module 13, a motor control module 14, an analog limit module 15, a voltage and current module 16 (divided into a total circuit voltage and current module 161, a limit control circuit voltage module 162 and a motor control circuit voltage module 163), a status display module 17 (divided into a motor enable indicator light 171, a motor control indicator light 172 and a limit control indicator light 173), an analog motor module 18, a control cable 19, a detection cable 20, a power cable 21, a microprocessor unit and system control software.

[0041] The device housing 11 is the main structure of the device and carries all components and circuits.

[0042] The power supply circuit 12 is composed of a power adapter module, which converts 220V AC power into 24V DC power to supply the lifting mechanism control circuit board and the detection device.

[0043] The motor enabling module 13 is composed of a jog switch and is used to control the working state of the simulated motor.

[0044] The motor control module 14 is composed of a jog switch, and when the motor is enabled, it controls the three states of the simulated motor: up, down and stop.

[0045] The simulation limit module 15 is composed of a jog switch. When the simulation motor is moving up or down, the upper and lower limit switches are switched to simulate the lifting mechanism touching the limit switch and changing from a moving state to a stopped state.

[0046] The voltage and current module 16 is composed of a voltage and current detection meter, which detects the voltage and current of the power supply circuit and the load circuit respectively, and determines whether each circuit works normally.

[0047] The status display module 17 is composed of status indicator lights, which respectively display the current working status of motor enable, motor control and limit control.

[0051] like Figure 6 As shown, the working process of the lifting mechanism control circuit board detection device is as follows: first, the lifting mechanism detection device is initialized to determine whether the motor is enabled. If not, continue to wait for the enable signal; if yes, determine the working state of the simulated motor according to the control instruction; if the motor control module sends a stop instruction, the simulated motor is in a stopped state; if the motor control module sends an uplink instruction, the simulated motor rotates forward; if the motor control module sends a downlink instruction, the simulated motor reverses; when the simulated motor is in a forward or reverse state and receives a limit instruction, the motor stops running; otherwise, the current operating state is maintained until the motor enable is turned off and the process ends.

[0052] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention.
