Description

Technical Field

[0001] This utility model relates to a status detection device, and more particularly to a status detection device for removing and adding a lid based on photoelectric sensor technology. Background Technology

[0002] In daily production and laboratory settings, various containers frequently require sealing, capping, and sample loading / uncapping. Traditional container capping and uncapping methods often lack effective detection methods, making it difficult to determine whether the capping / uncapping device is functioning properly and to promptly ascertain whether the cap has been successfully removed or replaced. Failure to detect capping / uncapping anomalies in a timely manner can lead to errors in subsequent production processes, sample contamination, or inaccurate experimental data, impacting production efficiency and work quality, and increasing manual inspection costs and error risks. While some detection methods exist, they suffer from low accuracy, slow response times, and complex structures, failing to meet the needs of actual production and work. Therefore, there is a strong need to design a capping / uncapping status detection device that is simple in structure, accurate in detection, and has a rapid response time. Summary of the Invention

[0003] This invention provides a cap-removing / applying status detection device based on a photoelectric sensor, solving the problem in existing technologies where the working status of the cap-removing / applying device and whether the cap has been successfully removed or placed are inaccurately determined, thus achieving rapid and accurate detection of the cap-removing / applying operation status. The cap-removing / applying status detection device based on photoelectric sensor technology includes a fixed bracket, a photoelectric sensor, a controller, and an alarm device. The fixed bracket is fixed behind the cap-removing / applying device and can move synchronously with it. The photoelectric sensor is mounted on the fixed bracket, with its emitting end facing the cap-removing / applying device. The photoelectric sensor is electrically connected to the controller and integrates light emission and reception functions. After the cap-removing or applying operation is completed and the cap-removing / applying device rises, the sensor emits infrared light and simultaneously receives the reflected light, converting the light intensity into an electrical signal. The alarm device is electrically connected to the controller and receives control signals from the controller to provide an alarm prompt. The controller presets a light intensity threshold and a judgment program. When it receives a signal transmitted from the signal processing module, it compares the corresponding light reflection intensity with the preset threshold. After the cap removal operation, if the intensity of the reflected light is greater than a preset threshold, it indicates that the infrared light is blocked and reflected by the cap within a certain distance, the cap is removed normally, and the controller determines that the cap removal operation is normal; if the intensity of the reflected light is less than the preset threshold, it indicates that the cap was not removed, and the controller determines that the cap removal operation is abnormal. After the cap addition operation, if the intensity of the reflected light is greater than the preset threshold, it indicates that the cap was not properly placed, and the controller determines that the cap addition operation is abnormal; if the intensity of the reflected light is less than the preset threshold, it indicates that the cap was successfully placed, and the controller determines that the cap addition operation is normal. Simultaneously, the controller activates the alarm device based on the determination results. Furthermore, the alarm device is an audible and visual alarm, which alerts the operator to malfunction by emitting sound and flashing lights. Compared with existing devices, this novel experimental device has a simple structural design, requires no complex mechanical structure or expensive testing equipment, reduces production and maintenance costs, and facilitates large-scale promotion and application.

[0007] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. The present invention is not limited to the specific embodiments disclosed below.

[0008] Please see Figure 1 In this invention, a cap removal and cap application status detection device based on a photoelectric sensor is provided, comprising: a cap removal and cap application device 1, a fixed bracket 2, a photoelectric sensor 3, a controller 4, an alarm device 5, a bottle cap 6, and a container bottle 7.

[0009] In this embodiment, the cap removal and cap application device 1 employs an electromagnet mechanism. The fixed bracket 2 is positioned directly behind the cap removal and cap application device 1 and can rise and fall synchronously with it. The photoelectric sensor 3 is mounted on the fixed bracket 2, with its emitting end facing the cap removal and cap application device 1. During installation, it is ensured that the light emitted by the sensor is not blocked by the cap removal and cap application device 1, and that when the cap application device 1 adsorbs the cap 6, the light is precisely blocked by the cap 6, thus achieving the detection function. During the cap removal operation, the cap removal device 1 adsorbs and raises the cap 6 of the container bottle 7. After the cap removal device 1 rises to a certain height and stabilizes, the photoelectric sensor 3 emits infrared light. If the cap 6 is properly removed, the infrared light will illuminate the surface of the cap 6 and reflect back to the photoelectric sensor 3. The photoelectric sensor 3 converts the intensity of the reflected light into an electrical signal, which is amplified and filtered by the signal processing module before being transmitted to the controller 4. The controller 4 compares the intensity of the reflected light corresponding to the received signal with a preset threshold cd. If the intensity is greater than the preset threshold cd, the controller determines that the bottle cap 6 has been properly removed and does not trigger the alarm device 5. If the bottle cap 6 has not been properly removed, the infrared light will shine on a distant obstruction and reflect back to the photoelectric sensor 3 for processing. The controller 4 compares the intensity of the reflected light corresponding to the received signal with a preset threshold cd. If the intensity is less than the preset threshold cd, the controller determines that the bottle cap 6 has not been removed and immediately controls the alarm device 5 to issue an audible and visual alarm to remind the operator to check.

[0010] During the capping operation, after the capping device 1 places the cap 6 onto the volumetric flask 7 and rises away, the photoelectric sensor 3 emits infrared light again. If the cap 6 is not correctly placed and remains attached to the cap removal device 1, the infrared light will be blocked and reflected by the cap 6. The photoelectric sensor 3 receives the reflected light and transmits the processed signal to the controller 4. The controller 4 determines that the capping operation is abnormal and triggers the alarm device 5 if the light reflection intensity is greater than the preset threshold cd. If the cap 6 is successfully placed, the infrared light will illuminate a distant obstruction, resulting in a weaker reflected light intensity. The controller receives the signal from the controller, and the light reflection intensity corresponding to this signal is less than the preset threshold cd, thus determining that the capping operation is normal, and the alarm device 5 does not sound.

[0011] Please see Figure 2 In this experiment, we place a barrier made of the same material as the bottle cap 6 at a horizontal straight-line distance of 3L from the photoelectric sensor 3. The distance sensor 3 emits infrared light that shines onto the surface of the barrier and is reflected back to the photoelectric sensor 3. The intensity of the light received by the photoelectric sensor 3 at this time, cd, is set as the threshold. When the horizontal straight-line distance between the photoelectric sensor 3 and the barrier is less than L, the intensity of the reflected light received by the distance sensor 3 will be greater than cd. When the horizontal straight-line distance between the photoelectric sensor 3 and the barrier is greater than L, the intensity of the reflected light received by the distance sensor 3 will be less than cd.
