Description

Technical Field

[0001] This utility model relates to the field of smoke detector fire alarm value calibration technology, and more specifically, to a smoke detector automatic calibration fire alarm value device. Background Technology

[0002] As a core device for fire early warning, the accurate calibration of the fire alarm threshold of a smoke detector directly affects its safety performance. A smoke detector needs to be assigned a fire alarm threshold at a certain smoke concentration. During use, when the external smoke concentration exceeds the fire alarm threshold, the smoke detector will trigger an alarm.

[0003] Currently, smoke detector fire alarm values ​​are calibrated manually or semi-automatically with mechanical assistance. During the calibration process, some products may be removed before calibration is completed, resulting in defective products and inconsistent calibration quality. Furthermore, operators who are exposed to smoke for extended periods may experience health risks. Utility Model Content

[0004] The technical problem to be solved by this utility model lies in the prior art. In view of the above-mentioned defects of the prior art, this utility model provides an automatic smoke detector calibration device for fire alarm values.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An automatic smoke detector calibration device for fire alarm values ​​includes a feeding component, an assembly component, and a calibration component;

[0007] The feeding assembly is used to transport the smoke detector to the assembly position. The feeding assembly includes a horizontally arranged conveyor belt, which is divided into a feeding area and a positioning area along the smoke detector's transmission direction. The positioning area is used to detect the material's arrival status.

[0008] The assembly assembly is used to assemble the upper and lower shells of the smoke detector. The assembly assembly includes an assembly table and a robotic arm. The assembly table serves as a workbench for assembling the smoke detector. The robotic arm is equipped with a vision positioning system.

[0009] The calibration component is used to calibrate the fire alarm threshold of the assembled smoke detector. The automatic calibration component includes a smoke chamber and a conveyor. The smoke chamber is used to set the fire alarm threshold, and the conveyor is used to convey the smoke detector into the smoke chamber.

[0010] By adopting the above technical solution, the feeding component transports the smoke detector to the assembly position via a conveyor belt, the assembly component assembles the upper and lower shells of the smoke detector, and the calibration component calibrates the fire alarm threshold of the assembled smoke detector. Through the division of labor and cooperation among the components, the process of smoke detector from transportation and assembly to fire alarm threshold calibration is automated. The beneficial effect is that, through modular design and automated operation, the efficiency and accuracy of smoke detector production are greatly improved, manual intervention is reduced, and production costs and the probability of errors are lowered.

[0011] Preferably, a reference optical fiber is provided on the side of the positioning area. The reference optical fibers are installed in pairs on the top of the brackets on both sides of the positioning area. The transmitting end and receiving end of the reference optical fiber are horizontally aligned. The distance between the transmitting end and receiving end of the positioning optical fiber covers the width of the transmission band.

[0012] By adopting the above technical solution and utilizing the optical signal transmission characteristics of the optical fiber, when the smoke detector reaches the positioning area and blocks the light, the receiving end cannot receive the signal, thereby detecting the material's arrival status. It can accurately determine whether the smoke detector has reached the designated position, providing an accurate trigger signal for subsequent assembly and calibration work, avoiding assembly errors or calibration failures caused by inaccurate material positions, and improving production stability and product qualification rate.

[0013] Preferably, the output end of the robotic arm is provided with a suction nozzle plate, which is a frustoconical shell. The inner wall of the suction nozzle plate is provided with a limiting protrusion, which is used to engage with the smoke detector shell. The suction nozzle plate is driven to rotate by a rotary cylinder, and the inside of the suction nozzle plate is coaxially threaded to the suction nozzle.

[0014] By adopting the above technical solution, the nozzle plate uses a limiting protrusion to engage with the smoke detector's outer shell, thus gripping the smoke detector. A rotary cylinder drives the nozzle plate to rotate, facilitating the adjustment of the smoke detector's posture and the assembly of the upper and lower shells. The threaded connection of the nozzle makes replacement and maintenance convenient. This system can stably grip the smoke detector, flexibly adjust its position and direction, improve assembly accuracy and efficiency, and simultaneously facilitate daily equipment maintenance and nozzle replacement, reducing equipment downtime and maintenance costs.

[0015] Preferably, the assembly table is a circular worktable, which is driven to rotate intermittently by a cam divider. The conveyor is mounted on the assembly table and has a loading position.

[0016] By adopting the above technical solution, the cam divider drives the assembly table to rotate intermittently according to a set program, allowing the smoke detectors to pass through different workstations in sequence. The conveyor accurately transports the smoke detectors to the loading position on the assembly table. The beneficial effect of this design is that it realizes the orderly flow of smoke detectors during the assembly process, enabling each assembly process to proceed in an orderly manner, improving assembly efficiency and the stability of the production cycle, while ensuring the positional accuracy of the smoke detectors during the assembly process.

[0017] Preferably, the conveying component includes a conveying plate, a drive rod, and a drive rail; the conveying plate is slidably connected to the drive rail via the drive rod, and the drive rod is driven by a cylinder.

[0018] By adopting the above technical solution, a cylinder drives a drive rod, which in turn moves a conveyor plate to slide on a drive guide rail, thereby realizing the transfer of smoke detectors between the assembly table and the calibration components. The structure is simple and reliable, capable of accurately and stably transferring smoke detectors. Furthermore, the cylinder drive allows for easy control of the transfer speed and position, ensuring the safety and accuracy of the smoke detectors during transfer and meeting the automated transfer requirements of the production process.

[0019] Preferably, a feed inlet is provided on the side wall of the tobacco chamber, and the feed inlet is set at the same horizontal height as the conveyor; a feed baffle is provided at the feed inlet, the feed baffle is slidably connected to the feed inlet, the feed baffle is driven by a cylinder, and a marker is provided inside the tobacco chamber, the marker corresponding one-to-one with the feeding position.

[0020] By adopting the above technical solution, when the conveyor delivers the smoke detector to the feed inlet, the cylinder drives the feed baffle to open, allowing the smoke detector to enter the calibration position in the smoke chamber. The beneficial effect of this design is that it ensures the smoke detector can smoothly and accurately enter the smoke chamber for fire alarm threshold calibration. Controlling the feed baffle prevents the smoke detector from entering the smoke chamber outside of calibration times, ensuring the accuracy and stability of the calibration process. Simultaneously, the correspondence between the calibration position and the feeding position ensures the consistency and traceability of the smoke detector calibration.

[0021] Preferably, the smoke chamber is divided into a smoke gathering chamber and a smoke dispersing chamber by a partition, and a smoke generating box is provided below the smoke chamber; the smoke generating box is connected to the top of the smoke gathering chamber by a pipe, and a solenoid valve is provided in the pipe to control the smoke flow; the smoke dispersing chamber is provided with a partition, and the partition divides the smoke dispersing chamber into two compartments.

[0022] By adopting the above technical solution, the smoke generating chamber produces smoke, which is controlled by a solenoid valve to enter the smoke gathering chamber. The smoke in the smoke gathering chamber is then evenly dispersed into the smoke distribution chamber through the smoke distribution holes, thus calibrating the fire alarm threshold of the smoke detector. This structure can provide a uniform and stable smoke environment for the smoke detector calibration, ensuring that the smoke detector can be calibrated under the same conditions, improving the accuracy and consistency of the calibration results. At the same time, the solenoid valve controls the smoke flow, making it easy to adjust the smoke concentration and calibration time, meeting the calibration requirements of different types of smoke detectors.

[0023] Preferably, a sorting component is provided on the side of the assembly component. The sorting component is used to transfer and unload the calibrated smoke detectors. The sorting component includes a first conveyor belt and a second conveyor belt, which are located on both sides of the unloading station of the turntable, respectively.

[0024] By adopting the above technical solution, the calibrated smoke detectors are transported to the first or second conveyor belt according to the set sorting rules at the rotary unloading station, realizing the classified transfer and unloading of smoke detectors. This enables rapid and accurate classification of calibrated smoke detectors, improving the continuity and efficiency of the production process, facilitating further processing or packaging of smoke detectors in different states or quality grades, and optimizing production management and product quality control.

[0025] The beneficial effects of this invention are as follows: By comparing the smoke-detecting material on the feed conveyor belt with the optical fiber, a collaborative robot arm equipped with a vision system is triggered to locate the product and use a suction cup to pick it up, placing it on the loading position of the assembly table. A rotary cylinder drives the suction cup to rotate, causing the product spring to contact the base spring. After the material is full, the cam divider drives the turntable to the calibration position, and the conveyor pushes the product into the smoke chamber. After the smoke chamber door closes, the fire alarm threshold is calibrated. During the calibration process, the robot arm simultaneously completes the unloading and loading. After calibration, the turntable rotates to complete the cycle. Its advantages are that it can be connected to an automatic line or assembly line to achieve automatic calibration of smoke alarm values, avoid damage to personnel from long-term exposure to smoke, ensure product calibration consistency, and improve production efficiency and quality stability.
