[0034] In order to make the purpose, technical solutions and advantages of the present application more clear, the following will combine the drawings in the present application to clearly and completely describe the technical solutions in the present application. Obviously, the described embodiments are some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0035] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "first"..."eighth" are numbering for the purpose of clearly identifying product components and do not represent any substantial difference. The terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this utility model according to the specific circumstances. Furthermore, "multiple" means two or more. In the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0036] The following is combined with Figures 1-3 This invention describes the temperature rise test chamber and temperature rise test system.

[0037] like Figure 1 As shown, the temperature rise test chamber provided in this embodiment of the present invention includes a chamber body, a thermal imaging device, and a robotic arm 3. The chamber body has a top wall 11, a bottom wall 12, and side walls. The side walls connect the top wall 11 and the bottom wall 12 to form an accommodating space for placing a sample under test. The thermal imaging device includes a first thermal imaging unit 21 and a second thermal imaging unit 22, which are respectively located on opposite sides of the side walls. The first thermal imaging unit 21 is used to capture a front thermal image of the sample under test, and the second thermal imaging unit 22 is used to capture a back thermal image of the sample under test. The robotic arm 3 and the first thermal imaging unit 21 are located on the same side of the chamber body. The robotic arm 3 can operate the sample under test according to control commands to switch the operating mode of the sample under test.

[0038] The chamber is equipped with a heating element to heat the air inside, providing a specific temperature testing environment for the sample under test.

[0039] In use, the top wall 11 is positioned above the bottom wall 12, and the side walls of the enclosure are vertical. For example... Figure 1 As shown, the first thermal imaging unit 21 and the robotic arm 3 are located on the right side inside the housing, and the second thermal imaging unit 22 is located on the left side inside the housing. The prototype under test is located in the middle of the housing, with its front facing the first thermal imaging unit 21 and the robotic arm 3, and its back facing the second thermal imaging unit 22. Typically, the operating interface of the prototype under test is located on its front. Placing the robotic arm 3 and the first thermal imaging unit 21 on the same side of the housing facilitates the robotic arm 3's operation of the prototype under test from the front.

[0040] Of course, there is also a case that the operation interface of the to-be-tested sample machine is located on the opposite side. In this case, the opposite side of the to-be-tested sample machine can face the first thermal imaging unit 21 and the mechanical arm 3, and the front side can face the second thermal imaging unit 22. In order to simplify the description, the front side and the opposite side in the embodiment only represent two opposite sides of the to-be-tested product, and do not mean that the to-be-tested product must have a specific front side and an opposite side, and must be constructed and operated in a specific orientation, and cannot be understood as a limitation on the embodiment.

[0041] During the test, the first thermal imaging unit 21, the second thermal imaging unit 22, and the mechanical arm 3 are respectively in communication connection with the upper computer. The first thermal imaging unit 21 and the second thermal imaging unit 22 transmit the front side thermal image and the opposite side thermal image captured to the upper computer, and the upper computer analyzes and judges the heating condition of the to-be-tested sample. After completing the test of one test scene, the upper computer sends a control instruction to the mechanical arm 3 to control the end of the mechanical arm 3 to operate the to-be-tested sample to switch the operation mode and enter the next test scene for testing.

[0042] Taking a mobile phone as the to-be-tested sample, the mobile phone can be arranged in a vertical direction in the box body, and the front side of the mobile phone faces the first thermal imaging unit 21 and the mechanical arm 3, and the opposite side faces the second thermal imaging unit 22. The end of the mechanical arm 3 is provided with a stylus, and the stylus is driven to perform touch operation on the screen of the mobile phone through the movement of the mechanical arm 3 to switch the operation mode of the mobile phone. For example, the operation mode of the mobile phone is switched to a high-definition video playing mode or a game mode.

[0043] The to-be-tested sample machine can be a static product or a dynamic product. When the to-be-tested sample machine is a dynamic product, the to-be-tested sample machine can be placed on the bottom wall 12, and the to-be-tested sample machine can move on the bottom wall 12. During the dynamic movement, the first thermal imaging unit 21 and the second thermal imaging unit 22 capture thermal images of the opposite sides of the to-be-tested sample machine. The mechanical arm 3 can also operate the dynamic to-be-tested sample machine to switch the operation mode.

[0044] The temperature rise test box provided by the embodiment of the utility model, through setting first thermal imaging unit 21 and second thermal imaging unit 22 on the opposite sides of the side wall of the box body respectively, and setting mechanical arm 3, mechanical arm 3 and first thermal imaging unit 21 are located on the same side of the box body, make mechanical arm 3 can switch the operation mode of to-be-tested sample machine according to control instruction, this temperature rise test box in the process of continuously testing multiple test scenes, do not need to open and close operation to the box body, avoided the influence of the temperature change in the box body caused by the opening and closing of the box body to affect the test, improved the test efficiency and test accuracy, saved the test manpower, both can test static product, also can test dynamic product, expanded the test object.

[0045] Further, as Figure 1As shown in the embodiment of this utility model, the thermal imaging device further includes a third thermal imaging unit 23. The third thermal imaging unit 23 is disposed on the top wall 11, and the sample under test can be placed on the bottom wall 12. The third thermal imaging unit 23 is used to capture a thermal image of the top of the sample under test.

[0046] When conducting temperature rise tests on dynamic products, the sample under test is placed on the bottom wall 12 and can move on the bottom wall 12. The third thermal imaging unit 23 captures a thermal image of the top of the sample under test. For example, this is used for temperature rise testing of a robotic vacuum cleaner.

[0047] In this embodiment of the utility model, the side wall of the box includes a box cover (not shown in the figure), and a first side wall 131, a second side wall 132, and a third side wall 133 connected in sequence. The first side wall 131 and the third side wall 133 are arranged opposite to each other and surround the top wall 11 and the bottom wall 12 to form an opening, and the box cover is disposed at the opening.

[0048] Specifically, the lid is rotatably connected to either the first side wall 131 or the third side wall 133, and the lid is rotated to open and close the box. When the lid is closed, the lid and the second side wall 132 are in a relative state. The first side wall 131, the second side wall 132, the third side wall 133, and the lid constitute the side walls of the box.

[0049] Optionally, heating elements are provided on the first sidewall 131, the second sidewall 132, and the third sidewall 133. Heating the air inside the chamber via these three spatially positioned heating elements accelerates the temperature rise rate within the chamber, shortens the waiting time during testing, and improves testing efficiency. Furthermore, covering the first sidewall 131, the second sidewall 132, and the third sidewall 133 with heating elements further ensures a more uniform temperature distribution within the chamber.

[0050] like Figure 2 As shown, the temperature rise test chamber provided in this embodiment of the present invention further includes a first slide rail 41, a second slide rail 42, a first clamp 51, and a second clamp 52. The first slide rail 41 is horizontally disposed on the second side wall 132, and the second slide rail 42 is horizontally connected between the first side wall 131 and the third side wall 133 and located at the opening. The first clamp 51 is slidably disposed on the first slide rail 41, and the second clamp 52 is slidably disposed on the second slide rail 42, so that the sample to be tested can be clamped between the first clamp 51 and the second clamp 52.

[0051] Specifically, the first slide rail 41 and the second slide rail 42 extend along a horizontal direction and can be arranged in parallel. The first clamp 51 is capable of sliding along the first slide rail 41, and the second clamp 52 is capable of sliding along the second slide rail 42. By adjusting the position of the first clamp 51 on the first slide rail 41 and the position of the second clamp 52 on the second slide rail 42, the distance between the sample machine to be tested and the mechanical arm 3 can be adjusted to ensure that the mechanical arm 3 can operate on sample machines of different sizes.

[0052] Optionally, at least one of the first clamp 51 and the second clamp 52 has an elastic telescopic end, and the sample machine to be tested is clamped between the first clamp 51 and the second clamp 52 under the elastic force of the elastic telescopic end, which also facilitates the taking and placing of the sample machine to be tested.

[0053] Specifically, as shown in Figure 2 the first clamp 51 and the second clamp 52 each include a bearing portion 511 and a clamping portion 512. The bearing portion 511 of the first clamp 51 and the bearing portion 511 of the second clamp 52 extend relative to each other along a horizontal direction. The clamping portion 512 is arranged along a vertical direction, and the sample machine to be tested is clamped between the clamping portion 512 of the first clamp 51 and the clamping portion 512 of the second clamp 52.

[0054] Specifically, the bearing portion 511 and the clamping portion 512 are connected to form an L-shaped clamp. The bearing portion 511 of the first clamp 51 and the bearing portion 511 of the second clamp 52 extend along a horizontal direction, i.e., the bearing portion 511 of the first clamp 51 extends horizontally from the clamping portion 512 of the first clamp 51 towards the opening, and the bearing portion 511 of the second clamp 52 extends horizontally from the clamping portion 512 of the second clamp 52 towards the second side wall 132.

[0055] When the sample machine to be tested is clamped between the first clamp 51 and the second clamp 52, the bottom of the sample machine to be tested is respectively borne on the bearing portion 511 of the first clamp 51 and the bearing portion 511 of the second clamp 52, and the two sides of the sample machine to be tested are respectively clamped between the clamping portion 512 of the first clamp 51 and the clamping portion 512 of the second clamp 52. In this way, the clamps can avoid shielding the test area of the sample machine to be tested, ensuring the accuracy of the test.

[0056] The first clamp 51 and the second clamp 52 each further include a connecting piece, and the clamping portion 512 is connected to the connecting piece by an elastic member to form an elastic telescopic end. The connecting piece of the first clamp 51 is slidingly arranged on the first slide rail 41, and the connecting piece of the second clamp 52 is slidingly arranged on the second slide rail 42.

[0057] As Figure 2As shown, the temperature rise test box provided by the embodiment of the utility model further includes first telescopic part 61 and / or second telescopic part 62. First telescopic part 61 is slidably arranged on first slide rail 41 and has a telescopic end that is telescopic towards the opening, and first clamp 51 is fixed on the telescopic end of first telescopic part. Second telescopic part 62 is slidably arranged on second slide rail 42 and has a telescopic end that is telescopic towards second side wall 132, and second clamp 52 is fixed on the telescopic end of second telescopic part 62.

[0058] In the above embodiment, the connecting part of first clamp 51 can be first telescopic part 61, and the connecting part of second clamp 52 can be second telescopic part 62. First telescopic part 61 and second telescopic part 62 can have the same structure and can both be electric push rods or telescopic sleeves.

[0059] On the one hand, the position of first clamp 51 on first slide rail 41 and the position of second clamp 52 on second slide rail 42 can be adjusted, and on the other hand, the distance between first clamp 51 and second clamp 52 can be adjusted by first telescopic part 61 and / or second telescopic part 62, so that the adjustment of the three-dimensional space of the clamping area can be realized to meet the clamping and fixing of the sample machine to be tested and the operation requirement of mechanical arm 3.

[0060] As shown, Figure 2 As shown, the temperature rise test box provided by the embodiment of the utility model further includes fifth slide rail 45, sixth slide rail 46, seventh slide rail 47 and eighth slide rail 48.

[0061] Specifically, fifth slide rail 45, sixth slide rail 46, seventh slide rail 47 and eighth slide rail 48 are arranged at the four corners of the side walls of the box body respectively, and are all provided with sliding grooves extending along the vertical direction. The four slide rails are all provided with a plurality of positioning holes along the vertical direction, and both ends of first slide rail 41 and second slide rail 42 are both provided with connecting holes corresponding to the positioning holes.

[0062] Both ends of first slide rail 41 are slidably arranged in the sliding grooves of fifth slide rail 45 and seventh slide rail 47, and the connecting holes at both ends correspond to the positioning holes on fifth slide rail 45 and seventh slide rail 47 respectively. Both ends of first slide rail 41 are positioned by bolts inserted into the connecting holes and the corresponding positioning holes.

[0063] The two ends of the second sliding rail 42 are slidingly arranged in the sliding grooves of the sixth sliding rail 46 and the eighth sliding rail 48, and the connecting holes at the two ends correspond to the positioning holes on the sixth sliding rail 46 and the eighth sliding rail 48 respectively.

[0064] Further, as shown in the utility model embodiment, the temperature rise test box further comprises a third sliding rail 43 and a fourth sliding rail 44. Figure 2 The first thermal imaging unit 21 is slidingly arranged on the third sliding rail 43, and the two ends of the third sliding rail 43 are slidingly arranged on a fifth sliding rail 45 and a sixth sliding rail 46 respectively.

[0065] The third sliding rail 43 and the fourth sliding rail 44 extend along the horizontal direction and can be arranged in parallel.

[0066] The connecting holes at the two ends of the third sliding rail 43 correspond to the positioning holes on the fifth sliding rail 45 and the sixth sliding rail 46 respectively, and the two ends of the third sliding rail 43 are positioned by inserting bolts into the connecting holes and the corresponding positioning holes.

[0067] The connecting holes at the two ends of the fourth sliding rail 44 correspond to the positioning holes on the seventh sliding rail 47 and the eighth sliding rail 48 respectively, and the two ends of the fourth sliding rail 44 are positioned by inserting bolts into the connecting holes and the corresponding positioning holes.

[0068] The two ends of the third sliding rail 43 are slidingly arranged in the sliding grooves of the fifth sliding rail 45 and the sixth sliding rail 46, and the two ends of the fourth sliding rail 44 are slidingly arranged in the sliding grooves of the seventh sliding rail 47 and the eighth sliding rail 48.

[0069] The utility model further provides a temperature rise test system, which comprises a host computer, a power supply and the temperature rise test box in any of the above embodiments.

[0070] The host computer is configured to control the power supply to charge the sample machine to be tested after determining that the power of the sample machine to be tested is lower than the set power, and determine the temperature of the sample machine to be tested to be reduced to the set temperature according to the thermal image captured by the thermal imaging device; and is further configured to determine the test area based on the thermal image after determining that the temperature is reduced to the set temperature; and is further configured to control the test to end after determining that the temperature of the sample machine to be tested is increased by no more than the set value within the set time period.

[0071] The power supply can be a program-controlled power supply. The power supply charges the sample machine to be tested according to the control instruction of the host computer. The heating element in the box is also in communication connection with the host computer.

[0072] As shown in Figure 3 Before starting the temperature rise test of the sample machine to be tested, the sample machine to be tested is placed in the box or clamped on the clamp. The host computer automatically detects the power of the sample machine to be tested. If the power is higher than the set power, such as 10% or 5%, the sample machine to be tested is controlled to discharge; if the power is lower than the set power, the host computer controls the thermal imaging device to capture the sample machine to be tested.

[0073] The host computer determines the temperature of the sample machine to be tested according to the thermal image captured by the thermal imaging device. After determining that the temperature of the sample machine to be tested is reduced to the set temperature, such as being reduced to the ambient temperature, the test area is determined by inputting the test point through the host computer.

[0074] The test personnel can perform three-point positioning through the front thermal image or the top thermal image on the host computer, frame the test area of the sample machine to be tested, or customize the frame of the test area of the sample machine to be tested. By three-point positioning, manual framing of the test area by the hand is avoided, and the error is reduced. After the test area is framed through the front thermal image, the test area can be synchronized to the second thermal imaging unit 22 through the host computer. After the test area is determined, the start test is clicked on the host computer.

[0075] During the test, the host computer controls the mechanical arm 3 to operate the sample machine to be tested to switch the test scene. The thermal imaging device performs temperature monitoring at a set time interval, such as every 1 second, based on the framed test area, determines the highest temperature point, and feeds back the temperature test data to the host computer. The host computer generates a chart according to the feedback test data and retains real-time data. The data can be set to be saved once every set time, such as ten minutes, to prevent data loss.

[0076] According to the test requirement of the actual product, the test end condition can be set through the host computer. In the embodiment, when the temperature of the tested sample machine does not increase by more than the set value within the set time period, the host computer determines that the test is ended. For example, if the temperature change is not more than 0.5 degrees within ten minutes, the temperature increase test is stopped, and the temperature increase stop is broadcasted. After determining that the test is ended, the host computer outputs the test report, controls the heating sheet of the temperature increase test box to stop heating, and controls the power supply to stop charging the tested sample machine.

[0077] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
