Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of sensor testing equipment, and in particular relates to a temperature and humidity sensor module testing device. Background Technology
[0002] Temperature and humidity sensor module testing refers to a series of verification and evaluation processes performed on temperature and humidity sensor modules to ensure that their performance, such as measurement accuracy, stability, response speed, and environmental adaptability, meets the design or application requirements.
[0003] In the testing of temperature and humidity sensors, constant temperature and humidity chambers are the foundation for testing accuracy, response time, and stability, and are used to accurately and stably control and maintain the required temperature and humidity environment.
[0004] Testing temperature and humidity sensors needs to be conducted in different environments. When switching environments, the door needs to be opened to place the sensor. However, after opening the door, the constant temperature and humidity inside the chamber will change, which will affect the accuracy of the test data and require waiting for the temperature and humidity to return to the predetermined values, taking up too much time.
[0005] To address the aforementioned issues, this application proposes a temperature and humidity sensor module testing device. Utility Model Content
[0006] The purpose of this invention is to provide a temperature and humidity sensor module testing device, which solves the problems mentioned in the background art.
[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0008] This utility model is a temperature and humidity sensor module testing device, including a constant temperature and humidity chamber;
[0009] The constant temperature and humidity chamber has a horizontal partition installed inside. The edge of the partition is connected to the inner wall of the constant temperature and humidity chamber, and one edge abuts against the inner wall of the chamber door. A vacuum unit is installed inside the cavity of the partition.
[0010] An opening is provided on the side of the constant temperature and humidity chamber away from the hinge of the chamber door, corresponding to the test space inside the constant temperature and humidity chamber. A fixed frame extends into the interior of the constant temperature and humidity chamber from the opening. A rotating sealing plate is rotatably installed above one end of the fixed frame inside the constant temperature and humidity chamber. When the movable end of the rotating sealing plate is vertically downward, it blocks the opening of the fixed frame.
[0011] The constant temperature and humidity chamber has a pull-out box that is slidably installed through an opening. The lower end of the pull-out box has an integral base for installing a temperature and humidity sensor. The upper end of the base has a test unit that is fixedly installed for electrical connection between the temperature and humidity sensor and the test element.
[0012] Preferably, a card plate is vertically slidably installed on the upper end of the fixing frame, and an elastic reset part connected to the top extension plate of the card plate is fixedly installed on the upper end of the fixing frame.
[0013] Preferably, the lower ends of the card plate have inclined guide edges on both sides.
[0014] Preferably, the upper end of the base is provided with a sealing frame that moves laterally, and the upper end of the sealing frame is provided with a guide edge engaging groove.
[0015] Preferably, a sealing folding curtain is fixedly connected between the sealing frame and the pull-out box.
[0016] Preferably, the bottom of both the sealing frame and the sealing folding curtain are slidably attached to the upper surface of the base, and when the end face of the sealing frame is attached to the plate extending upward from one end of the base, a sealing box is formed between the pull-out box and the base, the sealing frame and the sealing folding curtain.
[0017] Preferably, the fixing frame extends into the interior of the constant temperature and humidity chamber to support the base.
[0018] This utility model has the following beneficial effects:
[0019] 1. The temperature and humidity sensor is removed and placed by pulling it out from the side of the constant temperature and humidity chamber. Combined with the timely sealing treatment of the fixed frame by the rotating sealing plate, the sensor can be removed and placed without opening the chamber door. This helps to keep the temperature and humidity in the test space stable, which not only improves the accuracy of the test, but also saves the waiting time for the predetermined temperature and humidity to recover.
[0020] 2. By dividing the test space inside the constant temperature and humidity chamber with partitions and vacuuming adjacent test spaces, different temperature and humidity test environments exist simultaneously in a single device. This helps the temperature and humidity sensors switch environments, facilitates test operations, and saves on equipment investment costs and space.
[0021] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] In the description of this utility model, it should be understood that the terms "opening", "top and bottom", "thickness", "top", "middle", "length", "inner" and "around" indicate the orientation or positional relationship only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0037] A temperature and humidity sensor module testing device is provided to assist temperature and humidity sensors in testing under different temperature and humidity environments. The temperature and humidity sensor is taken out from the side of the constant temperature and humidity chamber 1 by pulling out a box 3 and placed in different test spaces inside the constant temperature and humidity chamber 1. This can improve the accuracy of test data after the temperature and humidity sensor changes environment and avoid the problem of temperature and humidity imbalance in the test space due to sensor switching.
[0038] In some embodiments, the specific structure of the temperature and humidity sensor module testing device is as follows: Figure 1-3 As shown, it includes a constant temperature and humidity chamber 1, a partition 2, a pull-out box 3, and a sealing mechanism;
[0039] The partition 2 is located in the middle layer area of the test space of the constant temperature and humidity chamber 1. It is a double-layer plate structure with an internal cavity. A pull-out box 3 is installed in the cavity to evacuate the cavity into a vacuum area to prevent the temperature and humidity of different test spaces from affecting each other.
[0040] The pull-out box 3, with a sealed plate structure, is installed at the side opening of the constant temperature and humidity chamber 1.
[0041] Among them, the pull-out box 3 has a base 31 extending into the constant temperature and humidity chamber 1 for placing temperature and humidity sensors. The upper end of the base 31 is equipped with a test unit 32, which contains the components required for testing. The test unit 32 is connected to the temperature and humidity sensors through the interface on the side.
[0042] The sealing mechanism is mainly a fixed frame 41, which extends into the interior of the constant temperature and humidity chamber 1 from the side opening. A rotating sealing plate 42 is rotatably installed on the upper end of the fixed frame 41, driven by a micro rotary motor, and is used to seal the opening of the fixed frame 41 located on one side inside the constant temperature and humidity chamber 1.
[0043] It is understandable that after the temperature and humidity sensor is installed on the base 31, it is inserted into the interior of the fixing frame 41 through the side opening of the constant temperature and humidity chamber 1, so as to realize the side removal and placement of the temperature and humidity sensor.
[0044] It is also understandable that when the base 31 is inside the constant temperature and humidity chamber 1, the movable end of the rotating sealing plate 42 is in a vertically upward state. After the base 31 is pulled out, the movable end of the rotating sealing plate 42 rotates to a vertically downward state, blocking the opening area of the fixing frame 41.
[0045] like Figure 4 As shown, the fixed frame 41 is adjacent to one end of the rotating sealing plate 42, and a sliding clamping plate 43 is inserted inside its upper end. The upper end of the clamping plate 43 extends laterally away from the rotating sealing plate 42 from the support plate.
[0046] Furthermore, an elastic reset part 44 is installed at the upper end of the fixing frame 41, and its upper end is connected to the lower surface of the support plate for applying a downward pulling force to the clamping plate 43.
[0047] In addition, the lower ends of the card plate 43 have inclined guide edges 431 on both sides. When the elastic reset part 44 is in normal state, the guide edges 431 enter the internal space of the fixing frame 41, and the upper edge is at the same height as the upper surface inside the fixing frame 41.
[0048] like Figure 5-6 As shown, a sealing frame 33 is movably installed on the inner side of the pull-out box 3, which can slide laterally along the side edge of the base 31.
[0049] Among them, a sealing folding curtain 331 is fixedly connected between the pull-out box 3 and the base 31 to seal the gap between the sealing frame 33 and the pull-out box 3 when the sealing frame 33 slides away from the pull-out box 3.
[0050] Furthermore, the upper end of the sealing frame 33 is provided with a slot 332 for engaging the lower end of the card plate 43 that extends out of the plate body. During the pushing and pulling process of the pull-out box 3, the opening edge of the slot 332 comes into contact with the guide edge 431.
[0051] The specific usage methods of temperature and humidity sensor module testing devices, as disclosed in some publications, are as follows:
[0052] S1: First, push the sealing frame 33 to one side of the pull-out box 3 to open the space above the base 31. Then, place the temperature and humidity sensor above the base 31 and connect it to the test element built into the test unit 32 through the connector on the side of the test unit 32.
[0053] S2: After the temperature and humidity sensor is installed, push the sealing frame 33 to the other end of the base 31 to seal the temperature and humidity sensor inside. Then push the base 31 into the interior of the constant temperature and humidity chamber 1 from the opening where the fixing bracket 41 is located. At this time, the movable end of the rotating sealing plate 42 is vertically upward.
[0054] S3: During the process of the base 31 entering the fixed frame 41, the edge of the sealing frame 33 first abuts against the edge of the guide edge 431, and moves it upward with the help of the pushing force. At this time, the elastic reset part 44 is stretched, thereby forming a downward pulling force on the card plate 43.
[0055] S4: When the slot 332 moves to below the guide edge 431, the pulling force of the elastic reset part 44 on the plate 43 causes the guide edge 431 to enter the interior of the slot 332, blocking the movement of the sealing frame 33.
[0056] S5: After the sealing frame 33 is blocked, the sealing folding curtain 331 is compressed as the base 31 goes deeper, so that the temperature and humidity sensor is placed in the test space of the constant temperature and humidity chamber 1.
[0057] S6: When it is necessary to switch the test environment of the temperature and humidity sensor, pull out the pull-out box 3. At this time, the compressed sealing folding curtain 331 will extend and open to keep the temperature and humidity sensor sealed and prevent external air from entering.
[0058] S7: When the sealed folding curtain 331 is extended to its longest state, it exerts a pulling force on the sealing frame 33. Based on the same principle in S3, the card plate 43 is pushed upward, releasing the obstruction on the sealing frame 33. At this time, the base 31 can be completely removed.
[0059] S8: When the end of the base 31 away from the pull-out box 3 enters the interior of the fixing frame 41, the rotating sealing plate 42 rotates downward to block the opening of the fixing frame 41 inside the constant temperature and humidity chamber 1. Finally, repeat the above steps to place the temperature and humidity sensor in another test space inside the constant temperature and humidity chamber 1.
