[0002] A smoke alarm is a safety device that can detect smoke and sound an alarm. Its basic principle is to sense smoke particles, convert the optical changes caused by smoke particles into electrical signals, and then process the signals and compare them with known fire standard data to determine whether a fire has occurred, and then send out an alarm signal to remind people to take timely countermeasures.

[0003] At present, smoke alarms using analog chips are still widely used because of their stable performance, strong anti-interference ability, low cost, etc. However, the sensitivity of such alarms is limited, and the potentiometer on the circuit board inside the alarm needs to be manually adjusted to calibrate the alarm threshold. In addition, when calibrating the sensitivity, the smoke sensing room is simulated by increasing the power of the transmitting tube to simulate the entry of smoke, and the sensitivity is not selected in a real smoke environment, resulting in a large discreteness of the calibrated sensitivity and poor accuracy.

[0004] In addition, workers need to confirm repeatedly when operating the debugging fixture and adjusting the potentiometer, which requires a lot of operating hours. Usually, several people are needed to operate together to improve production efficiency.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, in the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0025] In one embodiment, Figure 1 As shown, a control method for a smoke alarm automatic calibration machine is provided, and the method is applied to a controller as an example for explanation, and includes the following steps:

[0026] Step 101, controlling a workpiece conveying device to convey a circuit board of a smoke alarm into a smoke chamber.

[0027] The workpiece conveying device is used to convey the circuit board of the smoke alarm into or out of the smoke chamber, and can adopt a track conveying device or a manipulator conveying device, etc. The smoke chamber is arranged inside the chassis of the automatic calibration machine of the smoke alarm;

[0028] Specifically, the controller can control the track conveying device or other conveying devices to convey the circuit board of the smoke alarm into the smoke chamber.

[0029] Step 102: Control the smoke generating device to provide smoke of a preset calibration concentration to the smoke chamber.

[0030] The smoke generating device is connected to the smoke chamber to provide smoke into the smoke chamber; the smoke generating device includes a smoke generator and a smoke concentration control component, and the smoke concentration control component can evenly dilute the smoke generated by the smoke generator and input it into the smoke chamber, thereby obtaining smoke of a preset calibration concentration, and the preset calibration concentration is also the alarm threshold to be written into the smoke alarm;

[0031] Specifically, the controller can perform real-time detection of the smoke concentration in the smoke chamber by means of a first smoke concentration detection device arranged in the smoke chamber, and control the operation of the smoke generating device according to the detected smoke concentration until the smoke concentration in the smoke chamber reaches a preset calibration concentration; the first smoke concentration detection device includes an infrared transmitting end and an infrared receiving end relatively arranged on two sides of the chassis, and a filter is provided in front of the infrared receiving end to filter out interference from other visible light, thereby improving detection accuracy.

[0032] Step 103 , when the smoke concentration in the smoke chamber reaches a preset calibration concentration, the manipulator is controlled to adjust the potentiometer on the circuit board to calibrate the smoke alarm.

[0033] Specifically, when the smoke concentration detected by the first smoke concentration detection device is a preset calibration concentration, the controller can control the manipulator to adjust the potentiometer on the circuit board to calibrate the smoke alarm.

[0034] The principle of sensitivity calibration of smoke alarm is as follows: the analog smoke sensor chip has an output control port. When the smoke concentration detected by the alarm exceeds the calibrated threshold, this port will output a high level. Using this function, the manipulator in this embodiment will first adjust the potentiometer on the circuit board to be calibrated to the lowest sensitivity end. When the smoke concentration in the smoke chamber is at the preset calibration concentration, the manipulator will gradually adjust the potentiometer slowly toward the high end of the alarm sensitivity. Once the circuit board alarm is triggered and the output control port of the smoke sensor chip has a high level output, the manipulator will immediately stop adjusting. At this point, the smoke sensitivity adjustment is completed, and the calibration of the smoke alarm circuit board is also completed.

[0035] Among them, the manipulator includes a base and a fixed base which can move up and down along the base, a rotatable calibration rod is provided under the fixed base, the calibration rod is driven to rotate by a motor, and a calibration rod head for docking with a potentiometer is provided at the bottom end, and the potentiometer on the circuit board can be adjusted by the calibration rod head to calibrate the smoke alarm; specifically, the fixed base moves downward to make the calibration rod head dock with the potentiometer, and then the motor drives the calibration rod to rotate so that the calibration rod head adjusts the potentiometer to realize the calibration of the smoke alarm circuit board.

[0036] In the control method of the above-mentioned automatic calibration machine for smoke alarms, by controlling the smoke generating device, the smoke concentration in the smoke chamber can be accurately regulated, so that the circuit board to be calibrated can be calibrated in a real smoke environment, and the potentiometer is adjusted by an automated manipulator, which can effectively avoid errors caused by human negligence, thereby ensuring the sensitivity and accuracy of the calibration, which is beneficial to the improvement of the quality of the smoke alarm; at the same time, an automated workpiece conveying device is adopted, and the potentiometer is adjusted in conjunction with an automated manipulator, so that the potentiometers on one or more circuit boards can be adjusted at the same time to calibrate the sensitivity threshold, thereby greatly improving the production efficiency and helping to improve the production capacity of the alarm; therefore, the control method and system of the above-mentioned automatic calibration machine for smoke alarms can improve the production efficiency and product quality of smoke alarms.

[0037] In this embodiment, the smoke generating device includes a smoke generator, a smoke storage box and a fan unit arranged in the smoke chamber; Figure 2 As shown, step 102 includes:

[0038] Step 1021, controlling the smoke generator to generate smoke particles, and transporting the smoke particles to the smoke storage box through the pipeline.

[0039] Wherein, a smoke inlet fan, a smoke volume detection device and a second smoke concentration detection device are arranged in the smoke storage box.

[0040] Step 1022: Detect the smoke concentration in the smoke storage box by using the second smoke concentration detection device, and detect the smoke volume in the smoke storage box by using the smoke volume detection device.

[0041] Step 1023, when the smoke concentration in the smoke storage box reaches a preset smoke storage value, the smoke inlet fan is controlled to transport the smoke in the smoke storage box to the smoke chamber.

[0042] Step 1024, controlling the fan unit to operate until the mixed smoke reaches a preset calibration concentration.

[0043] When the fan unit is working, the smoke chamber inhales air through the air inlet and evenly mixes the air and smoke entering the smoke chamber. A filtering device is provided on the air inlet of the smoke chamber.

[0045] During the specific implementation process, the smoke generated by the smoke generator first enters the smoke storage box through the pipeline, and after reaching a stable concentration in the smoke storage box, it is discharged from the smoke storage box into the smoke chamber, and then circulates in the smoke chamber under the action of the fan unit; the first smoke concentration detection device can detect the smoke concentration in the smoke chamber in real time, and send the detection value to the controller; in order to provide a stable smoke output, the smoke inlet fan, the second smoke concentration detection device and the smoke volume detection device arranged in the smoke storage box can, under the control of the controller, reduce or increase the amount of smoke output to the smoke chamber according to the detected smoke concentration in the smoke chamber, so that it can automatically adjust to a preset smoke concentration range.

[0049] Specifically, each fan in the fan unit can be individually controlled to start and stop, and the speed of each fan can be individually controlled according to the fan control instruction input by the user, the real-time smoke concentration in the smoke chamber and the fan speed data.

[0050] In the above embodiment, the speed of each fan can be controlled individually, which can make the smoke more uniform and the control more precise.

[0051] In this embodiment, the workpiece conveying device includes a conveying track and a bearing platform slidably arranged on the conveying track, and one or more clamps are arranged on the bearing platform;

[0052] Step 101 includes:
