[0002] Automated storage and retrieval systems (AS / RS), also known as high-bay warehouses, are highly integrated warehousing systems. AS / RS utilizes racks that are several, dozens, or even hundreds of layers high to store goods. With the help of automated equipment and technologies such as stacker cranes, conveyors, control systems, and computer management systems, they can achieve automated storage and retrieval of goods, significantly improving space utilization.

[0003] Shuttle cars are used in automated warehouses (AS / RS). The shuttles transport containers across various platforms within the AS / RS via elevators. To prevent the shuttles from falling off the platform tracks, stoppers are installed at the track ends. To improve the stability of these stoppers, their activation must be tested to ensure they function properly within the AS / RS. Currently, manually assembling the stoppers and directly installing them at the AS / RS track ends makes it impossible to effectively determine their functionality. To prevent malfunctions during operation, effective testing of the stoppers before installation is necessary. Therefore, this invention provides a stopper testing device. Utility Model Content

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. The technical solutions provided by each embodiment of this utility model will be described in detail below with reference to the accompanying drawings.

[0032] To better understand the purpose of this utility model, it will be described in further detail below.

[0033] Please see Figures 1 to 7 This utility model discloses a blocker detection device for detecting blockers 3. The blocker detection device includes: a connecting frame 1, a support frame 2, a detection photoelectric device 4, a quick clamp 5, a push block 6, and a linear stepper motor 7.

[0034] One side of the connecting frame 1 is used to install the support frame 2 and the linear stepper motor 7, and the other side of the connecting frame 1 is used to connect to external devices. The top of the support frame 2 is provided with a first track 8 and a second track 9, which are used to install the stopper 3. The top of the support frame 2 is also provided with the quick clamp 5 and the push block 6.

[0035] The linear stepper motor 7 is used to push the push block 6 to reciprocate. The quick clamp 5 is used to press and fix the block 3 on the support frame 2. When the push block 6 is driven by the linear stepper motor 7, the push block 6 pushes the block 3 to move. The detection photoelectric device 4 is installed on the side wall of the support frame 2. The detection photoelectric device 4 is used to detect the state of the block 3.

[0036] The connecting frame 1 serves as the basic structure of the entire testing device. One end is used to mount the support frame 2 and the linear stepper motor 7, while the other end is used to connect to external equipment. It provides stable support and connection functions, allowing other components to be securely installed and work together.

[0037] The support frame 2 is mounted on the connecting frame 1, and the top is used to install the stopper 3, the detection photoelectric device 4, the quick clamp 5, and the push block 6.

[0038] The component being detected, blocker 3, is monitored by a photoelectric detection device 4, which typically detects the state of blocker 3 by detecting changes in the position of the flip block 302 on blocker 3. This real-time capture of the blocker's motion state provides a basis for subsequent data processing and state determination.

[0039] The quick clamp 5 presses and fixes the stopper 3 on the support frame 2 to prevent it from moving or shaking during the testing process.

[0040] Pusher 6 is driven by linear stepper motor 7, which pushes stopper 3 to reciprocate. This simulates the force conditions of the stopper in actual use and tests its performance under different motion states.

[0041] Linear stepper motor 7 provides the power source, driving pusher block 6 to reciprocate. The movement speed and stroke of the stopper are controlled to ensure the detection process proceeds according to predetermined parameters. After the detection device is started, quick clamp 5 presses and fixes the stopper 3 onto the support frame 2. Linear stepper motor 7 then starts working, driving pusher block 6 to reciprocate. Pusher block 6 pushes the stopper 3 to move, simulating the force conditions in actual use. Detection photoelectric device 4 detects the state changes of the stopper 3 in real time, especially the position changes of the flipping block. After multiple reciprocating movements, detection photoelectric device 4 collects sufficient data for subsequent analysis.

[0042] The detection photoelectric device 4 is connected to the control device or a remote host computer. The detection photoelectric device 4 transmits the collected data to the host computer or control system for processing. The data is analyzed using preset algorithms or logical rules to determine whether the performance of the blocker 3 meets the requirements. Based on the data analysis results, the detection device can provide feedback signals to the operator or generate a detection report, indicating whether the blocker is qualified.

[0043] This utility model discloses a barrier detection device that simulates the force and motion state of a barrier in actual use. It uses a photoelectric detection device to capture the changes in the barrier's state in real time, and combines it with components such as a linear stepper motor and a quick clamp to accurately evaluate the barrier's performance. This effectively solves the problem that it is impossible to effectively determine whether a barrier is qualified when it is directly installed at the end of the automated warehouse track after manual assembly, thus improving the reliability of the automated warehouse.

[0044] When the detection photoelectric device 4 detects the state of the blocker 3, it involves a series of data processing steps. The detection photoelectric device 4 needs to be initialized, including configuring the sensitivity, threshold parameters and data processing algorithms of the photoelectric sensor, to capture and identify the motion state of the blocker 3.

[0045] When the blocker 3 starts to move, the photoelectric detection device 4 continuously collects light signal data, reflecting the position change of the flip block 302 of the blocker 3. The photoelectric sensor converts the light signal into an electrical signal and generates raw data.

[0046] The raw data collected contains noise or outliers, so preprocessing is required. Preprocessing steps include filtering (such as low-pass filtering) to remove high-frequency noise and data smoothing to reduce random fluctuations.

[0047] In the preprocessed data, features related to the state of the blocker 3 are extracted. The position information of the flip block 302 is determined by detecting changes in the photoelectric signal; for example, when the flip block 302 moves from the inside to the outside, the intensity of the light signal received by the photoelectric sensor changes.

[0048] Based on the extracted features, a preset algorithm or logic rule is applied to determine the current state of the blocker 3. If the flipping block 302 is detected to change from a lying state to an upright state (or vice versa), it can be determined that the blocker 3 has completed one motion cycle.

[0049] The judgment result is recorded and can be transmitted to a host computer or control system via an interface (such as USB, Ethernet, etc.). Simultaneously, based on the judgment result, the photoelectric detection device 4 can also send a feedback signal to the control system to indicate whether the blocker 3 is functioning correctly.

[0050] The above steps are repeated multiple times to achieve a comprehensive test of the blocker 3. By summarizing and analyzing the results of multiple tests, the performance and stability of the blocker 3 can be evaluated more accurately.

[0051] It is important to note that the specific data processing steps will vary depending on the actual application scenario and testing requirements. The steps described above provide a basic framework, which needs to be adjusted and optimized according to specific circumstances in actual applications.
