[0001] This utility model relates to the field of product manufacturing environment testing technology, specifically to a constant temperature testing device. Background Technology

[0002] In fields such as electronics manufacturing, semiconductor packaging, new energy batteries, and precision components, product performance and reliability are highly dependent on their behavior under specific temperature conditions. Therefore, isothermal testing is an indispensable and critical step in the production process. This step requires placing the item under test in a preset constant temperature environment for a period of time to simulate actual usage conditions or accelerate aging in order to detect its electrical characteristics, functional stability, and potential defects.

[0003] Traditional testing methods often rely on manual operation, such as using a single large oven or freezer. The operator must manually place the product to be tested into the equipment, wait for the test to complete, and then manually remove it. This process is not only labor-intensive and prone to errors, but also causes drastic temperature fluctuations inside the testing chamber each time the door is opened to remove or place the product. It takes extra time for the temperature to return to the set value, resulting in a shortened effective testing time and inaccurate test results. Utility Model Content

[0033] Please see Figures 1 to 6 This embodiment provides a constant temperature testing device, including: a conveying assembly 1, a temperature measuring fixture 2, and a gantry gripping robot 3. The conveying assembly 1 is used to convey the items to be tested. The temperature measuring fixture 2 includes a test box 21, a slider 22, a slide rail 23, and a temperature measuring unit. The test box 21 is disposed on top of the slider 22, and the slider 22 is slidably disposed on the slide rail 23. The temperature measuring unit includes a lifting component 25, a lifting cover plate 251, and a probe 252. The lifting component 25 is disposed on one side of the slide rail 23. The lifting cover plate 251 is disposed above the slide rail 23, and the detection rod 252 is disposed below the lifting cover plate 251. One end of the detection rod 252 is connected to the lifting cover plate 251. The lifting cover plate 251 is movably connected to the lifting component 25, and the lifting cover plate 251 reciprocates in a direction perpendicular to the slide rail 23. The gantry gripping robot arm 3 is straddling the conveying component 1 and the temperature measuring fixture 2, and is used to transfer the test item on the conveying component 1 into the test box 21.

[0034] The conveying assembly 11 is a mechanism responsible for automatically conveying the items to be tested within the equipment. This assembly receives the items from the upstream production line and transports them to a position easily grasped by the gantry gripping robot 3, thus automating and continuousizing the testing process. The temperature measuring fixture 22 is the core functional unit of the constant temperature testing equipment, responsible for containing and testing the items to be tested. The test box 21, through the base 211 and baffle 212, forms a semi-enclosed chamber 213 to house the items to be tested, providing a separate testing space for each item. This facilitates precise control of the temperature within the space and prevents mutual interference when multiple products are in the same chamber. Disturbances or uneven temperatures; the slider 22 is installed below the test box 21 and is the carrier for its movement. The slide rail 23 is a track fixedly installed on the equipment base. The protrusion 221 on the slider 22 is nested or slidably connected to the slide rail 23. The slide rail 23 provides a precise and low-friction guide track for the movement of the slider 22, so that the test box 21 can move smoothly along the set trajectory; the gantry gripper 3 is a multi-degree-of-freedom automated mechanical device with a "gate" shaped structure. It is responsible for gripping the items to be tested from the conveyor assembly 1 and transferring them to the designated temperature measuring fixture 22, realizing the automatic, continuous and precise transfer of the items to be tested between the conveyor line and multiple test stations. Specifically, after the item to be tested is transported to the designated position by the conveying component 1, the gantry gripper 3 transfers it into the chamber 213 of the test box 21. The slider 22 moves along the slide rail 23, driving the test box 21 into the test area. After the test is completed, the test box 21 exits the test area, and the gantry gripper 3 grabs the item in the test box 21 and transfers it to the conveying component 1 to enter the next test cycle.

[0035] By using an array of independently distributed temperature measuring fixtures 2, combined with a gantry gripping robot 3 and a conveying assembly 1 to form an automated material flow, the problem of manual operation intervention is avoided, significantly improving testing efficiency and ensuring the uniformity and stability of the test. At the same time, the modular design of the temperature measuring fixtures 2 greatly enhances the flexibility and ease of maintenance of the equipment, solving the core problems of low efficiency, insufficient automation and difficult maintenance of traditional constant temperature testing equipment.

[0036] Please see Figure 3 and Figure 4 In this embodiment, there are multiple temperature measuring fixtures 2, and the multiple temperature measuring fixtures 2 are arranged in an array on one side of the conveying component 1. The multiple temperature measuring fixtures 2 arranged in an array on one side of the conveying component 1 significantly improves the efficiency of the device, allowing multiple items to be tested to undergo constant temperature testing in parallel and independently in space. Each temperature measuring fixture 2 operates as an independent temperature control unit without interfering with each other, thereby multiplying the overall testing throughput of the device. At the same time, this tightly arranged array structure greatly saves the overall footprint of the device and improves space utilization.

[0037] Please see Figures 1 to 2 In this embodiment, the test box 21 includes a baffle 212 and a base 211. There are two baffles 212, which are disposed opposite to each other on the top of the base 211. The two baffles 212 and the base 211 enclose a cavity 213, which is used to accommodate the item to be tested. The test box 21 consists of a base 211 and baffles 212. Specifically, the base 211 forms the basic support platform at the bottom of the chamber 213. The baffles 212 are set vertically or at a specific angle on the top edge of the base 211. There are two baffles 212, which are arranged opposite each other. The chamber 213 formed between the baffles 212 is open on both sides, which facilitates the gantry gripper 3 to take out and put in the test items. Compared with the complex cavity of integral casting or welding, the combination of base 211 and baffles 212 is simple in structure, easy to process, and lower in cost. Moreover, the cooling airflow blown in by the fan can act more directly and effectively on the internal space of the chamber 213 and the surface of the test items, improving heat exchange efficiency and ensuring the uniformity and stability of the temperature field. At the same time, by adjusting the number, shape or position of the baffles 212, the chamber 213 can be flexibly adapted to test items of different sizes and specifications, expanding the application range of the equipment.

[0038] Please see Figures 1 to 2 In this embodiment, the slider 22 has a protrusion 221 at its bottom, and a groove at the bottom of the protrusion 221. The slide rail 23 is placed in the groove. The temperature measuring fixture 2 also includes a moving module, which is located on one side of the slide rail 23 and connected to the slider 22 to drive the slider 22 to move on the slide rail 23. Optionally, there are four protrusions 221, which are rectangularly distributed at the bottom of the slider 22. The bottom surface of the protrusion 221 (i.e., the side that contacts the slide rail 23) has a groove that extends along the direction in which the slider 22 needs to move. The top contour of the slide rail 23, which is fixed on the equipment base, is precisely embedded in and confined within the groove at the bottom of the protrusion 221. The enveloping constraint of the groove on the slide rail 23 effectively suppresses vibration, shaking, and noise during the sliding process, improving the stability and lifespan of the equipment.

[0039] Please see Figures 1 to 2 In this embodiment, the inner wall of the baffle 212 is provided with a fixing groove 2123, the upper part of the baffle 212 is provided with a break 2121, the fixing groove 2123 is provided on both sides of the break 2121, the periphery of the break 2121 is provided with a sealing groove 2122, and the bottom of the lifting cover 251 is provided with two sealing plates 2511 opposite to each other. When the lifting cover 251 covers the top of the test box 21, the sealing plate 2511 is accommodated in the sealing groove 2122, and the probe 252 is accommodated in the fixing groove 2123.

[0040] Each baffle 212 has a break 2121, with two breaks 2121 facing each other and roughly U-shaped. Each baffle 212 has two fixing grooves 2123, located on both sides of the break 2121 on the baffle. The fixing grooves 2123 are longitudinal grooves. The sealing groove 2122 is a groove machined around the edge of the break 2121. The lifting component 25 is located on one side of the slide rail, and the lifting cover plate 251 on the lifting component 25 is located above the slide rail. The lifting cover plate 251 can move in a direction perpendicular to the slide rail. The probe 252 is adapted to the sealing plate 2511. The probe 252 is set between the two sealing plates 2511, and its axis is perpendicular to the lifting cover plate 251. The number of probes 252 is the same as the number of fixing slots 2123. The lifting cover plate 251 moves down to cover the top of the test box 21. At this time, the probe 252 is inserted into the fixing slot 2123 to perform real-time temperature detection. The sealing plate 2511 is housed in the sealing slot 2122. The chamber 213 inside the test box 21 is a chamber with one side open, which accelerates the convection effect of the cooling airflow and avoids local overheating inside the test box 21, which would affect the accuracy of the test results.

[0041] Please see Figure 3 and Figure 5 In this embodiment, the conveying assembly 1 includes an infeed speed line 11, an outfeed speed line 12, and a conveyor 13. The outfeed speed line 12 is arranged parallel above the infeed speed line 11, and the conveyor 13 is movably connected to the outfeed speed line 12 and the infeed speed line 11. The outfeed speed line 12 is stacked above the infeed speed line 11, forming a compact vertical layout. The test items produced upstream are conveyed into the equipment through the infeed speed line 11. The conveyor 13 is movably connected to the outfeed speed line 12 and the infeed speed line 11, vertically transferring the test items on the infeed speed line 11 to the outfeed speed line 12. The outfeed speed line 12 conveys the test items to the gripping area of ​​the gantry gripper 3, where the gantry gripper 3 transfers the test items to the temperature measuring fixture 22 for constant temperature testing. This structure greatly saves equipment floor space, automates and continues the testing process, eliminates manual handling, significantly improves efficiency, reduces human error, and ensures the orderly and efficient flow of items to be tested.

[0042] Please see Figure 3 , Figure 4 and Figure 6In this embodiment, the gantry gripping robot 3 includes a moving beam 31 and a moving track 32. There are two moving tracks 32, which are arranged opposite to each other. The moving beam 31 is mounted on the two moving tracks 32 and moves back and forth along the extension direction of the moving track 31. The gantry gripping robot 3 also includes a robot body 33, which is mounted on the moving beam 31 and moves back and forth along the extension direction of the moving beam 31. One end of the robot body 33 is provided with two grippers 331, which move vertically. The moving track 32 is a rack and pinion track. The moving crossbeam 31 is also equipped with a transmission rod, with gears fixed at both ends. The surface of the rack and pinion track 32 is equipped with a rack structure. The gears on the transmission rod mesh with the rack. The motor on the moving crossbeam 31 drives the transmission rod to rotate, thereby enabling the moving crossbeam 31 to move in the direction of extending the rack and pinion track 32. The robot arm body 33 is equipped with a gear and rack transmission device to enable the gripper 331 to move in the vertical direction. At the same time, the robot arm body 33 can move on the moving crossbeam 31, allowing the gripper 331 to move freely inside the equipment, enabling fast and accurate gripping and placement of the test items, and improving the working efficiency of the equipment.

[0043] Please see Figure 5 In this embodiment, the testing equipment also includes a housing 4, within which the conveying assembly, temperature measuring fixture, and gantry gripper are all housed. The bottom of the housing has multiple pulleys and multiple support legs, while the top of the housing has multiple lifting rings. The housing 4 integrates the conveying assembly 1, temperature measuring fixture 2, and gantry gripper 3 into a closed space, physically isolating them from external airflow disturbances and mechanical vibrations, ensuring the stability of the temperature field inside the test chamber. The pulleys and lifting rings on the housing allow for flexible position adjustment of the equipment within a certain range. The support legs provide rigid support to the equipment upon contact with the ground; simultaneously, the height of the support legs is adjustable, eliminating the influence of uneven ground and ensuring stable placement of the equipment.
