Description

Technical Field

[0001] This application relates to the field of product testing technology, specifically to a temperature and humidity detection system and a test chamber. Background Technology

[0002] Currently, electronic products undergo reliability testing before leaving the factory. The most common and effective test is a temperature and humidity test that simulates environmental conditions. For example, the sample to be tested is placed in a temperature and humidity test chamber and tested according to a preset temperature and humidity profile. Throughout the operation, a temperature and humidity meter is typically positioned in a fixed location within the test chamber to sense simulated temperature and humidity parameters, thereby adjusting the temperature and humidity within the chamber to stabilize them at the required test values.

[0003] However, since there is a certain spatial distance between the sample actually located on the grid plate of the test chamber and the thermometer and hygrometer at the fixed position, errors will occur due to the influence of unrelated materials in the air conduction path of the simulated temperature and humidity. For example, the test chamber side wall or grid plate absorbs energy and causes loss, or the airflow loop causes the simulated temperature and humidity to flow to other positions outside the sample surface. Furthermore, since the number and position of the sample are dynamically changing each time, there will be a certain error in the detection of the temperature and humidity on the sample surface.

[0027] It should also be noted that the methods disclosed in the embodiments of this application or the methods shown in the flowcharts include one or more steps for implementing the method. Without departing from the scope of the claims, the execution order of multiple steps can be interchanged, and some steps can also be deleted.

[0028] Currently, electronic products undergo reliability testing before leaving the factory. The most common and effective test is a temperature and humidity test that simulates environmental conditions. For example, the sample to be tested is placed in a temperature and humidity test chamber and tested according to a preset temperature and humidity profile. Throughout the operation, a temperature and humidity meter is typically positioned in a fixed location within the test chamber to sense simulated temperature and humidity parameters, thereby adjusting the temperature and humidity within the chamber to stabilize them at the required test values.

[0029] However, since there is a certain spatial distance between the sample actually located on the grid plate of the test chamber and the thermometer and hygrometer at the fixed position, errors will occur due to the influence of unrelated materials in the air conduction path of the simulated temperature and humidity. For example, the test chamber side wall or grid plate absorbs energy and causes loss, or the airflow loop causes the simulated temperature and humidity to flow to other positions outside the sample surface. Furthermore, since the number and position of the sample are dynamically changing each time, there will be a certain error in the detection of the temperature and humidity on the sample surface.

[0030] This application provides a temperature and humidity detection system and a test chamber for improving the accuracy of obtaining temperature and humidity information of test samples.

[0031] Please refer to Figure 1 , Figure 1 This is a schematic block diagram of a temperature and humidity detection system for a test chamber, provided in an embodiment of this application. The temperature and humidity detection system 100 includes a position detection device 110, a distance detection device 120, a temperature and humidity detection device 130, and a controller 140. In this embodiment, the position detection device 110 is disposed on a grid plate inside the test chamber, and the position detection device 110 is used to acquire the position information of the planar sample placed on the grid plate.

[0032] The distance detection device 120 is located above the grid disk and is used to obtain the height information of the test sample inside the chamber.

[0033] The temperature and humidity detection device 130 is located above the grid plate and includes a first moving mechanism connected to the housing. The first moving mechanism is used to control the temperature and humidity detection device 130 to move to a preset height above the test sample after receiving a moving command.

[0034] In this embodiment, the controller 140 receives the position and height information of the planar sample, generates and outputs a temperature and humidity detection command based on the position information, and generates and outputs a movement command based on the height information. The temperature and humidity detection device 130, upon receiving the temperature and humidity detection command, detects the temperature and humidity information below the corresponding planar position and transmits the information to the controller 140.

[0035] It is understood that in the temperature and humidity detection system 100 of this solution, the position detection device 110 first acquires the planar sample position information of the test sample on the grid, that is, the planar position of the test sample. At the same time, the distance detection device 120 acquires the height information of the test sample, that is, the overall height of the test sample. The controller 140 controls the first moving mechanism to move the temperature and humidity detection device 130 to a preset height above the test sample according to the planar sample position information and the height information, and controls the temperature and humidity detection device 130 to collect the temperature and humidity information above the test sample, thereby improving the accuracy of acquiring the temperature and humidity information of the test sample.

[0036] In some embodiments, such as Figure 2 As shown, the test chamber 10 contains, from bottom to top, the aforementioned position detection device 110, distance detection device 120, and temperature and humidity detection device 130. The position detection device 110 is located below the grid plate 11 of the test chamber 10, the distance detection device 120 is located above the grid plate, and the temperature and humidity detection device 130 is located above the grid plate. The first moving mechanism of the temperature and humidity detection device 130 can be located on an inner side wall of the test chamber 10.

[0037] Among them, such as Figure 2As shown, a display panel can also be provided on one outer side wall of the test chamber 10. The display panel is connected to the controller 140 and is used to display the information output by the controller 140. For example, it can output the temperature and humidity information obtained by the controller 140 in real time through the temperature and humidity detection system 100. In some embodiments, the display panel is a touch display panel, and parameters such as the corresponding sampling frequency and the preset height of the test sample can also be input through the touch display panel.

[0038] In this embodiment, in response to the position detection device 110 determining that the test sample is placed on the grid and the door of the test chamber 10 is closed, the controller 140 can control the distance detection device 120 to detect the height of the test sample to obtain the height information of the test sample, and then control the temperature and humidity detection device 130 to move to a preset height above the test sample using the height information.

[0039] Please refer to Figure 3 , Figure 3 This is a schematic block diagram of a distance detection device provided in an embodiment of this application. The distance detection device 120 includes a light source emitter 121, a light source receiver 122, a second moving mechanism 123, and a third moving mechanism 124.

[0040] In this embodiment, the light source emitter 121 is disposed on the second moving mechanism 123, and the light source receiver 122 is disposed on the third moving mechanism 124. The second moving mechanism 123 and the third moving mechanism 124 are disposed opposite to each other in the housing and are parallel. The controller 140 is also used to control the second moving mechanism 123 and the third moving mechanism 124 to move the light source emitter 121 and the light source receiver 122 upward from the horizontal plane of the grid disk. The height information is determined by detecting the number of beams emitted by the light source emitter 121 and the number of beams received by the light source receiver 122.

[0041] In some embodiments, height information is determined when it is detected that the number of beams emitted by the light source emitter 121 is consistent with the number of beams received by the light source receiver 122.

[0042] The controller 140 is also used to control the second moving mechanism 123 and the third moving mechanism 124 in response to the position detection device 110 determining that the test sample is placed on the grid, so that the light source emitter 121 and the light source receiver 122 move to the horizontal plane of the grid.

[0043] It is understandable that after determining that a test sample is placed in the grid, the controller 140 can first control the second moving mechanism 123 and the third moving mechanism 124 to move the light source emitter 121 and the light source receiver 122 to the horizontal plane of the grid, and then reset the light source emitter 121 and the light source receiver 122 before controlling them to move from bottom to top. It is also understandable that during the movement, if the number of emitted beams is inconsistent with the number of received beams, it indicates that a test sample is obstructing the movement; when the number of emitted beams and the number of received beams are exactly the same, it indicates that the highest point of the test sample has been reached, thus determining the height information of the test sample.

[0044] In some embodiments, a first reset point can be set at the horizontal position of the grid disk, and a second reset point can be set above the test chamber. For example, the second reset point can be the top layer of the chamber or the highest point of that layer in the chamber. The distance X1 from the first reset point to the second reset point can be pre-recorded in the controller 140. When detecting the height of the test specimen, the distance detection device 120 can be reset to the first reset point, and the temperature and humidity detection device 130 can be reset to the second reset point. The height of the test specimen is obtained as X2 through the distance detection device 120. Then, according to the preset height X3, the controller 140 can calculate the distance that the temperature and humidity detection device 130 moves downward from the second reset point as X1-X2-X3.

[0045] In some embodiments, after determining that a test sample is placed in the grid, the controller 140 can also control the second moving mechanism 123 and the third moving mechanism 124 to move the light source emitter 121 and the light source receiver 122 to a target height above the grid, and then control the light source emitter 121 and the light source receiver 122 to move downwards. It can be understood that during the movement, when the number of emitted beams matches the number of received beams, it indicates that there is no test sample obstructing the view; when the number of emitted beams and the number of received beams are exactly different, it indicates that the highest point of the test sample has been reached, thereby determining the height information of the test sample.

[0046] In this embodiment, the light source emitter 121 is a heat-free light source, such as an LED light source.

[0047] Please refer to Figure 4 , Figure 4 This is a schematic block diagram of a temperature and humidity detection device provided in an embodiment of this application. The temperature and humidity detection device 130 includes a mesh sampling pipe 131, a wind compressor 132, and a temperature and humidity detector 133.

[0048] In this embodiment, the air compressor 132 is connected to the mesh sampling pipe 131 and the temperature and humidity detector 133, respectively. The mesh sampling pipe 131 is provided with multiple sampling holes. The controller is also used to control the air compressor 132 to extract gas above the test sample from the mesh sampling pipe 131 and transmit it to the temperature and humidity detector 133 to obtain the temperature and humidity information of the temperature and humidity detector 133.

[0049] The mesh sampling pipe 131 includes multiple wavy sub-pipes that bend at an angle around the positive Z-axis, thereby increasing the number of sampling holes per unit area and thus increasing sampling efficiency.

[0050] In some embodiments, the pipe nodes of the mesh sampling pipe 131 are equipped with electronic valves 1311. The controller is also used to control the electronic valves 1311 above the test specimen to open according to the planar sample position information, so as to control the sampling holes above the test specimen to collect gas, thereby obtaining the temperature and humidity analog information of the gas above the test specimen, thereby further improving the accuracy of collecting the temperature and humidity information of the test specimen.

[0051] In some embodiments, the temperature and humidity detection device 130 further includes a circulation pipe 134. The circulation pipe 134 is connected to the cavity of the temperature and humidity detector 133 and is used to discharge the gas detected by the temperature and humidity detector 133 back into the test chamber.

[0052] Please refer to Figure 5 , Figure 5 This is a schematic block diagram of a position detection device provided in an embodiment of this application. The position detection device 110 includes a pressure sensor array 111.

[0053] In this embodiment, the controller 140 is further configured to receive pressure array information from the pressure sensor array 111 and determine the planar sample position information based on the pressure array information. The pressure sensor array 111 includes multiple uniformly distributed pressure sensors, and the position information of each pressure sensor is pre-stored in a preset storage space. After acquiring the pressure sensor data, the controller 140 compares the pressure sensor data with the position information in the preset storage space to obtain the planar sample position information of the test specimen.

[0054] Please refer to Figure 6 , Figure 6 This is a schematic block diagram of a test chamber provided in an embodiment of this application. The test chamber 600 includes a temperature and humidity control system 610 and a temperature and humidity detection system 620 from any of the above embodiments.

[0055] In this embodiment, the temperature and humidity control system 610 is used to receive the temperature and humidity information output by the temperature and humidity detection system 620 and control the temperature and humidity values ​​inside the test chamber 600 to remain within a preset range.

[0056] In some embodiments, such as Figure 7 As shown, the test chamber 600 also includes a sample placement system 630, which includes an image acquisition device 631, a robotic arm 632, and a robotic arm controller 633. The image acquisition device 631 is disposed above the grid or on the cavity wall inside the test chamber, and is used to acquire images of the sample being placed, and transmit these images to the robotic arm controller 633. The robotic arm controller 633 receives the images and, based on the images and a preset motion trajectory, controls the robotic arm 632 to place the sample onto the grid.

[0057] Please refer to Figure 8 , Figure 8 A control method for a temperature and humidity detection system of a test chamber provided in this application embodiment, applied to the test chamber in any of the above embodiments, specifically includes the following steps: Step S81: In response to the selection of the preset connected placement route, acquire the image inside the test chamber, and control the robotic arm to place the test sample on the grid plate according to the connected placement route based on the image.

[0058] In this embodiment, the aforementioned connected placement route is a pre-set route for placing the test specimens on the grid. The connected placement route ensures that the test specimens are placed on a single route, so that the positions of each test specimen on the grid are closer together, thereby making the temperature and humidity control of each test specimen in the test chamber more accurate. Furthermore, since the route is connected, when the target pipe node is opened, the sampling space can be connected as a whole and flow to the temperature and humidity detection device, thereby obtaining more accurate sampled analog quantities.

[0059] Step S82: Reset the distance detection device to the first reset point, reset the temperature and humidity detection device to the second reset point, obtain the height of the test sample as X2 through the distance detection device, and calculate the distance that the temperature and humidity detection device moves downward from the second reset point as X1-X2-X3 based on the preset height X3 of the test sample.

[0060] Step S83: Control the temperature and humidity detection device to move down from the second reset point X1-X2-X3.

[0061] Step S84: Receive the pressure array information of the pressure sensor array, determine the planar sample position information of the test specimen based on the pressure array information, and use the planar sample position information to perform coincidence mapping with the position of the pipe nodes of the mesh sampling pipe to obtain the target pipe node set.

[0062] Step S85: Control the opening of the electronic valves of the target pipeline nodes according to the target pipeline node set.

[0063] Step S86: Receive the input sampling frequency, control the air compressor to extract the gas above the test sample from the mesh sampling pipe and transmit it to the temperature and humidity detector, and control the temperature and humidity detector to detect the gas temperature and humidity according to the corresponding sampling frequency.

[0064] Step S87: Display the detected temperature and humidity in real time on the test chamber's display interface, and adjust the internal environment of the test chamber based on the detected temperature and humidity and the target temperature and humidity.

[0065] In some embodiments, such as Figure 9 As shown, step S81 above may further include the following steps: Step S811: Display the preset connected placement route on the display interface of the test chamber.

[0066] Step S812: In response to the opening of the test chamber door and the selection of the preset connected placement route, control the image acquisition device to acquire the image inside the test chamber, and identify the junction of the grid and the door as the initial placement side based on the image recognition.

[0067] Step S813: Detect the border position of the previous test specimen based on the image. Based on the border position of the previous test specimen and the preset distance, control the robotic arm to move the current test specimen from the initial placement side into the test chamber and place it on the connected placement path of the grid disk.

[0068] In some embodiments, in scenarios where the test chamber is not equipped with a robotic arm for placing test samples, after the test chamber's display interface shows a preset connected placement route, the user can also manually place the test sample into the test chamber from the initial placement side according to the connected placement route, which is not limited here.

[0069] In some embodiments, such as Figure 10 As shown, step S84 above may further include the following steps: Step S841: Perform planar coordinate mapping based on the pressure array information to obtain the planar position area coordinates of the test sample on the grid disk.

[0070] Step S842: Divide the plane of the mesh sampling pipeline into regions based on the pipeline nodes to obtain multiple sampling areas.

[0071] Step S843: Traverse all sampling areas, filter out target sampling areas that intersect with the coordinates of the planar position area, and obtain the pipe nodes within the target sampling area as target pipe nodes.

[0072] In some embodiments, such as Figure 11 As shown, step S85 above may further include the following steps: Step S851: Determine the connected area for temperature and humidity sampling based on the connected placement route and the target pipe node.

[0073] Step S852: Obtain the target pipe node at the edge of the connected region as the edge pipe node, and determine the opening direction of the electronic valve of the edge pipe node according to the direction of the edge of the connected region.

[0074] Step S853: Control the opening of the electronic valves at the edge pipe nodes according to the opening direction of the electronic valves, and control the electronic valves of the remaining target pipe nodes within the connected area to open in all directions.
