BRIEF DESCRIPTION OF THE DRAWINGS
[0015] Figure 1 It is a schematic diagram of the external structure of a programmable constant temperature and humidity testing machine.
[0016] Figure 2 It is a structural diagram of a programmable constant temperature and humidity testing machine. DETAILED DESCRIPTION
[0017] The present invention is further described in detail below in conjunction with specific implementation methods.
[0018] The programmable constant temperature and humidity test machine of this embodiment is shown in FIG. Figure 1 , including a cabinet 1, a controller and a display device 21. The cabinet 1 is provided with a closed door 2. The display device 21 is installed on the closed door 2 on the outer side of the cabinet. The display device 21 is connected to the controller for communication. The cabinet 1 is provided with a plurality of test boxes for placing a plurality of devices to be tested. Figure 2 Position detectors 51 are provided on the inner wall of the test box 5 at positions corresponding to the placement areas of the devices to be tested. The position detectors 51 are connected to the controller in communication. The position detector 1 is used to send an occupation signal to the controller when the placement area of the devices to be tested is occupied. The controller is used to control the display device 21 to display the occupation status of the placement area of the devices to be tested according to the received occupation signal, so that the staff can accurately identify the placement status of the devices to be tested.
[0019] Five position detectors 51 are arranged horizontally and equidistantly on the inner wall of the test box 5. The distance between each two adjacent position detectors 51 can accommodate a device to be tested. A temperature sensor 52 is provided at the edge of the inner wall of the test box 5. The position detector 51 is specifically a pair of infrared transmitting-receiving sensors arranged on two opposite inner walls of the test box 5. If the infrared transmitting-receiving sensors are blocked, the signal between the two is interrupted, and a signal that the device to be tested is detected is sent to the controller. A test interface for connecting the temperature sensor and all position detectors is provided on the outside of the test box. When the test box is installed in the cabinet, the test interface is used to connect the power supply and the controller of the programmable constant temperature and humidity tester, so as to power the temperature sensor and the position detector and receive their detection data. When the programmable constant temperature and humidity tester is in the starting state, before the test work is performed, all the position detectors 51 in the test box 5 are started. If the detection result is that the device to be tested is placed in the placement area, the controller controls the display device 21 to display the placement area as a green light. If the detection result is that no device to be tested is placed in the placement area, the controller controls the display device 21 to display the placement area as a red light. At the same time, the temperature sensor 52 in the test box 5 is activated to measure the temperature of the test box 5 , and the measured temperature in the test box 5 is displayed on the display device 21 .
[0020] Among them, a drainage hole 3 is opened on the side of the cabinet 1, and the drainage hole 3 leads to the outside of the cabinet 1 through a water pipe. During the low-temperature test, the moisture in the air condenses into liquid water and drips down to the bottom of the cabinet 1 cavity, and then is discharged to the outside of the cabinet 1 through the water pipe in the drainage hole 3 to avoid affecting the test.
[0021] The test box 5 includes a heat-insulating interlayer 6 arranged on the side wall and a heating element 7 arranged on both ends. The heat-insulating interlayer 6 includes two layers of asbestos cloth and a ceramic heat-insulating board sandwiched between the two layers of asbestos cloth, forming a multi-layer heat-insulating structure in which two layers of asbestos cloth wrap the ceramic heat-insulating board, so that the ceramic heat-insulating board is not easy to break and can play a good heat-insulating effect.
[0022] The cabinet 1 is provided with a closed door 2, which is buckled to the cabinet 1 through a card-type bumper 3, so as to achieve a good closing effect. The card-type bumper 3 includes a bumper seat and a buckle that are buckled together, the bumper seat is installed on the cabinet 1, and the buckle is installed on the closed door 2.
[0023] Among them, a moving component 4 is arranged at the bottom of the cabinet 1, and the moving component 4 includes an elastic pad installed at the bottom of the cabinet and casters installed at the bottom of the elastic pad, the casters are provided with brakes, and the elastic pad includes stacked multiple layers of insulating films, which is convenient for moving and parking the cabinet and has good thermal insulation effect.
[0024] The above is only an implementation method of the utility model, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the utility model, which still fall within the scope of patent protection.
