Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of aluminum alloy surface treatment, in particular to a constant temperature and humidity operating table suitable for detection tests including scratching, cupping, bending and pencil hardness of aluminum alloy surface treatment samples. Background Art
[0002] According to the surface treatment testing standards 9286-2021, 9753-2007, 6742-2007, 6739-2002, etc., the test environment for cross-cutting, cupping, bending, pencil hardness and other tests must be carried out at a temperature of 23℃±2 and a humidity of 50%±5, which is a relatively harsh temperature and humidity environment. In the summer, the temperature and humidity in the laboratory are high, and in the winter, the temperature and humidity in the laboratory are low. If the test is to be carried out, the laboratory environment needs to be adjusted in advance through air conditioning and humidifier-dehumidifier.
[0003] The current method of laboratory temperature and humidity regulation has the following disadvantages:
[0004] 1. Low work efficiency and long time for temperature and humidity control: Even in a small laboratory, the laboratory space is large. It takes a long time to adjust the test environment in a large space through air conditioning and humidification condensers.
[0005] 2. Low precision of temperature and humidity control: The sealing effect between the laboratory and the outdoors is not good. The entry and exit of test personnel during the test will cause changes in temperature and humidity in the laboratory. The temperature and humidity of the test environment in the laboratory vary greatly, and the test accuracy has a certain impact on the test results.
[0006] 3. The test environment is demanding: The test environment must at least be well sealed, have a humidifier, and have air conditioning. Testing cannot be done directly on the production line or outdoors. This will make it impossible to monitor the quality of the product and provide timely feedback to production, which will indirectly increase the scrap rate. Utility Model Content

DETAILED DESCRIPTION
[0035] In order to better explain the present invention and facilitate understanding, the technical scheme and effects of the present invention are described in detail below through specific implementation modes in conjunction with the accompanying drawings.
[0036] like Figure 1-5 As shown, a constant temperature and humidity operating table includes an outermost test box 7, a test box door 1 with a herringbone shape on the top connected to the top of the test box 7 through a hinge 13, and the test box door 1 can be rotated and opened along the hinge 13; the test box door 1 is closed with the test box 7 by engaging the test box door switch buckle 5 on the test box 7 with the handle on it. The test box door 1 is provided with a glass window 2, and the operator can observe the test equipment and samples in the box through the glass window 2.
[0037] A foldable rubber baffle 3 is installed in the middle area of the glass window 2. The operator can flexibly move left and right along the edge of the test box 7 in the rubber baffle 3 area without affecting the operation. Two rubber tubes 14 are installed on the rubber baffle 3, and the tube bodies are installed side by side facing the inside of the test box 7. The operator's arm can enter the test box 7 through the rubber tube 14 to perform the operation test, and the rubber tube 14 fits tightly with the arm and will not affect the temperature and humidity in the test box. A rotating cap is set at the end of the rubber tube 14, and the rotating cap can be covered when not in operation.
[0038] The top of the test box 7 is in a herringbone shape. The test personnel need to stand on one side of the herringbone door when operating. The test personnel's arm needs to be inserted into the rubber baffle 3 on one side of the door. When the personnel operates, the arm will be at an angle of about 45° to the vertical direction. The test box door 1 is designed in a herringbone shape to facilitate the test personnel's operation.
[0039] like Figure 6 As shown, the foldable rubber baffle 3 is shaped like an accordion bellows, including wavy rubber folds, which increases the space for the arm to move left and right during operation; it presents a W-shaped wave shape parallel to the direction of the glass window 2, and the upper and lower areas of the W-shaped rubber baffle 3 are connected to a rubber baffle with a certain thickness, so there will be no sealing problems.
[0040] like Figure 7-8 As shown, the rotating cap is threadedly connected to the end of the rubber tube 14, and a handle is provided on the inner side of the rotating cap. The rotating cap can be easily installed and removed by rotating the handle.
[0041] A sealing rubber strip 19 is glued to the top of the test box 7. When the test box door handle 4 and the test box door switch buckle 5 are locked, the test box door 1 can fit tightly with the sealing rubber strip 19 on the upper side of the test box 7 to ensure the sealing of the test box.
[0042] The test box 7 is provided with a temperature air conditioner 26 and a humidity regulator 23 on the left and right sides of the lower part. The back of the temperature air conditioner 26 is connected to the air conditioning exhaust air inlet 9 provided on the test box 7, and the temperature inside the box is regulated by replacing the hot and cold air inside and outside. The humidity regulator 23 is a commercially available product, and is equipped with a sprayer and a condenser. The humidity inside the box can be regulated by increasing the ambient humidity through the sprayer and reducing the ambient humidity through the condenser. A temperature and humidity probe 22 is installed on the upper wall of the inner side of the test box 7, and the temperature and humidity of the area above the test bench 18 can be monitored through the temperature and humidity probe 22.
[0043] The test box 7 is provided with a controller (not shown in the figure), and the motor 25, the temperature and humidity probe 22, the temperature air conditioner 26 and the humidity regulator 23 are electrically connected to the controller. The front of the test box 7 is provided with a control panel 6 electrically connected to the controller, which can set the temperature and humidity in the box and control the start and stop of the motor 25. The temperature and humidity monitored by the temperature and humidity probe 22 are fed back to the controller in time, and the temperature air conditioner 26 and the humidity regulator 23 are controlled by the controller to adjust the temperature and humidity. A motor 25 is fixed at the center below the test box 7, and the output end of the motor 25 is connected to the test bench 18 through the rotating shaft 24, and the test bench 18 is provided with test equipment. The rotation of the motor 25 drives the test bench 18 to rotate, so that the test equipment to be done is rotated to the direction of the operating port, that is, the direction of the glass window 2.
[0044] A cupping device 15, a scratching device 16, a sample 17, a pencil hardness device 20, and a bending device 21 are placed above the test bench 18, respectively, for testing the surface treatment performance of the sample.
[0045] The test box 7 has a detachable water tank 10 at the back, which is connected to a humidification water inlet pipe 11 and a condensation water outlet pipe 12. The end of the humidification water inlet pipe 11 is connected to the sprayer of the humidity regulator 23. If the test box 7 needs to be humidified, the water in the water tank 10 is sprayed into the test box 7 along the humidification water inlet pipe 11; the end of the condensation water outlet pipe 12 is connected to the condenser of the humidity regulator 23 in the test box 7. If the test box 7 needs to be dehumidified, the water collected by the condenser in the humidity regulator 23 will flow back to the water tank 10 along the condensation water outlet pipe 12. In order to prevent the water in the water tank 10 from being contaminated by the test environment, the water in the water tank 10 needs to be replaced regularly.
[0046] Four pulleys 8 are installed at the lower side of the test box 7 to facilitate the position transfer of the test box 7.
