Description

Technical Field

[0001] This utility model belongs to the technical field of temperature shock test chambers, and specifically relates to a split-type temperature shock test chamber. Background Technology

[0002] A temperature shock test chamber is a device used to test the performance and reliability of products under extreme temperature rapid alternation environments. By instantly switching between high and low temperature environments, it simulates harsh temperature change scenarios and tests the tolerance of materials, electronic components, or industrial products to thermal shock (such as cracking, aging, functional failure, etc.). It is widely used in electronics, automotive, aerospace and other fields.

[0003] The core feature of the split-type temperature shock test chamber is that the high-temperature zone and the low-temperature zone are designed as independent modules (split structure), and the temperature shock test of the sample is realized through a rapid switching system.

[0004] According to a temperature shock test chamber disclosed in Chinese Patent Publication No. CN222490095U, by using a transmission device to pull the second handle outward, the moving wheel at the bottom of the side plate will compress the limiting buckle set on the slide plate downward, so that the moving wheel can slide out and drive the flat plate to the outside. The staff can take out the test sample placed in the upper part of the flat plate from the outside, without the need for manual entry into the equipment to take out the test sample.

[0005] However, in the aforementioned devices and existing technologies, when removing the test sample from inside the equipment, it is necessary to open the corresponding hot and cold chambers inside the equipment and then pull the test sample out of the equipment along the guide rail. However, at the moment the hot and cold chambers are opened, the high-temperature (or low-temperature) medium accumulated inside will form a rapid outflow due to pressure changes. When the staff performs the extraction action by hand, the high-temperature heat wave or low-temperature cold flow can directly act on the extremities, causing instantaneous heat conduction damage (burns or frostbite). At the same time, the outflow of hot and cold air causes the surface temperature of the workpiece to fluctuate, making it impossible for the workpiece to reach the preset temperature impact conditions during the test, thus affecting the accuracy of the test results. Utility Model Content

[0006] In response to the problem in related technologies that the high-temperature (or low-temperature) medium accumulated inside the hot and cold chamber will form a rapid outflow due to pressure changes when the chamber is opened, causing instantaneous heat conduction damage when the operator performs the extraction action by hand, this utility model proposes a split-type temperature shock test chamber to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model is a split-type temperature shock test chamber, including a temperature shock test chamber body. The temperature shock test chamber body is provided with a high temperature zone, a material handling zone and a low temperature zone. The temperature shock test chamber body is provided with a lifting mechanism inside. The lifting end of the lifting mechanism is provided with an isolation mechanism. The isolation mechanism is provided with a picking mechanism inside. One end of the picking mechanism is provided with a rotating mechanism.

[0009] The workpiece is placed by the rotating end of the rotating mechanism, and the lifting end of the lifting mechanism is used to drive the isolation mechanism to move up and down, so that the isolation mechanism drives the workpiece in the rotating mechanism to switch between the high temperature zone, the material handling zone and the low temperature zone. The isolation end of the isolation mechanism is driven to separate the high temperature zone, the material handling zone and the low temperature zone. When the workpiece reaches the material handling zone, the picking mechanism is moved laterally to take the workpiece out of the material handling zone.

[0010] Furthermore, the lifting mechanism includes a motor, which is fixedly connected to the top of the temperature shock test chamber body. The output shaft of the motor is fixedly connected to a lead screw, which is rotatably connected inside the temperature shock test chamber body. A lifting frame is threaded onto the surface of the lead screw, and the lifting frame is slidably connected inside the temperature shock test chamber body.

[0011] Furthermore, the isolation mechanism includes an isolation frame, which is fixedly connected to one end of the lifting frame. An upper extension column is slidably connected to one end of the isolation frame, and an upper extension partition is fixedly connected to one end of the upper extension column. A lower extension column is slidably connected to the other end of the isolation frame, and a lower extension partition is fixedly connected to one end of the lower extension column. Multiple springs are fixedly connected to one end of both the upper and lower extension columns, and one end of each spring is fixedly connected inside the isolation frame.

[0012] Furthermore, sealing rings are fixedly installed below the upper extension partition and above the lower extension partition, respectively, and the upper extension partition and the lower extension partition are slidably connected inside the high temperature zone and the low temperature zone.

[0013] Furthermore, the taking mechanism includes a sliding plate, which is slidably connected inside the isolation frame. Two springs are fixedly connected to both sides of the sliding plate, and one end of each spring is fixedly connected inside the isolation frame.

[0014] Furthermore, the rotating mechanism includes a turntable, which is rotatably connected to the surface of a sliding plate. A gear is fixedly connected to one end of the turntable, and a rack meshes with the surface of the gear. The rack is slidably connected inside the isolation frame.

[0015] Furthermore, a second motor is fixedly installed on one side of the isolation frame, and an eccentric disk is fixedly connected to the output shaft of the second motor. A reciprocating rod is rotatably connected to the eccentric end of the eccentric disk, and one end of the reciprocating rod is fixedly connected to one end of the rack.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model uses a rotating mechanism to carry the workpiece, and a lifting mechanism to drive the isolation mechanism to move vertically. This causes the workpiece on the surface of the rotating mechanism to switch between a high-temperature zone, a material handling zone, and a low-temperature zone according to a preset trajectory. The isolation mechanism achieves physical separation between the three zones through a dynamic airtight isolation end, reducing the leakage rate of the cavity during the switching process. When the workpiece is transferred to the material handling zone, the transverse picking mechanism takes the workpiece out of the material handling zone, ensuring that the temperature fluctuation throughout the process is within the range that does not affect the detection values. This forms a split-type multi-zone collaborative operation system of "closed transfer - precise separation - efficient picking and placing". At the same time, zoned detection and picking and placing will not cause burns or frostbite to the staff due to the leakage of hot and cold air.

[0018] 2. This utility model uses a motor to drive an eccentric disk to rotate, which in turn drives a reciprocating rod to slide. The reciprocating rod then drives a rack to move back and forth inside the isolation frame, causing the rack to drive a gear to rotate back and forth. This causes the gear to drive a turntable to rotate on the surface of a sliding plate, resulting in the turntable rotating slowly back and forth. This allows the workpiece located on the surface of the turntable to rotate slowly back and forth, ensuring that the workpiece can be heated or cooled evenly within the high-temperature and low-temperature zones, preventing the workpiece from experiencing excessively high or low temperatures in certain areas.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0031] Please see Figures 1-6 As shown, this utility model is a split-type temperature shock test chamber, including a temperature shock test chamber body 1. The temperature shock test chamber body 1 is provided with a high temperature zone 2, a material handling zone 3 and a low temperature zone 4. The temperature shock test chamber body 1 is provided with a lifting mechanism 5 inside. The lifting end of the lifting mechanism 5 is provided with an isolation mechanism 6. The isolation mechanism 6 is provided with a picking mechanism 7 inside. One end of the picking mechanism 7 is provided with a rotating mechanism 8.

[0032] The workpiece is placed by the rotating end of the rotating mechanism 8, and the lifting end of the lifting mechanism 5 is used to drive the isolation mechanism 6 to move up and down, so that the isolation mechanism 6 drives the workpiece in the rotating mechanism 8 to switch between the high temperature zone 2, the material handling zone 3 and the low temperature zone 4. The isolation end of the isolation mechanism 6 is driven to separate the high temperature zone 2, the material handling zone 3 and the low temperature zone 4. When the workpiece reaches the material handling zone 3, the workpiece is taken out of the material handling zone 3 by the transverse picking mechanism 7.

[0033] By opening the cabinet door of the material handling area 3 inside the temperature shock test chamber body 1, the picking mechanism 7 is moved laterally, causing the rotating end of the rotating mechanism 8 driven by the picking mechanism 7 to reach the outside of the temperature shock test chamber body 1. The workpiece is then placed on the surface of the rotating end of the rotating mechanism 8. The picking mechanism 7 is then reset, simultaneously moving the workpiece back to the material handling area 3. The cabinet door of the material handling area 3 inside the temperature shock test chamber body 1 is then closed. The temperature adjustment devices for the high-temperature zone 2 and low-temperature zone 4 inside the temperature shock test chamber body 1 are activated, causing the high-temperature zone 2 and low-temperature zone 4 to reach their corresponding temperatures. The lifting end of the lifting mechanism 5 drives the isolation mechanism 6 to move up and down, causing the isolation mechanism 6 to rotate. The workpiece within mechanism 8 switches between high-temperature zone 2 and low-temperature zone 4. The isolation end of the synchronous drive isolation mechanism 6 separates high-temperature zone 2, material handling zone 3, and low-temperature zone 4 to prevent temperature leakage between high-temperature zone 2 and low-temperature zone 4. Then, the workpiece's resistance to thermal shock is tested. After that, the workpiece is transported to material handling zone 3, the cabinet door of the corresponding material handling zone 3 is opened, and the workpiece is taken out of the material handling zone 3 by the transverse handling mechanism 7. The rotation mechanism 8 can drive the workpiece located on the rotating end surface to rotate, so that the workpiece can be heated or cooled evenly inside high-temperature zone 2 and low-temperature zone 4, preventing the local temperature of the workpiece from being too high or too low.

[0034] The workpiece is carried by the rotating end of the rotating mechanism 8. The lifting mechanism 5 adopts the vertical movement of the linear drive isolation mechanism 6, which drives the workpiece on the surface of the rotating mechanism 8 to switch between the high temperature zone 2, the material handling zone 3 and the low temperature zone 4 according to a preset trajectory. The isolation mechanism 6 realizes the physical separation of the three zones through the dynamic airtight isolation end, which reduces the leakage rate of the cavity during the switching process. When the workpiece is transferred to the material handling zone 3, the transverse picking mechanism 7 takes the workpiece out of the material handling zone 3, ensuring that the temperature fluctuation of the whole process is within the range that does not affect the detection value. This forms a split multi-zone collaborative operation system of "closed transfer - precise separation - efficient picking and placing". At the same time, the zoned detection and picking and placing will not cause burns or frostbite to the staff due to the leakage of hot and cold air.

[0035] Furthermore, in specific applications, the temperature shock test chamber body 1 is equipped with a high-temperature zone 2, a material handling zone 3, and a low-temperature zone 4. Each zone has a corresponding cabinet door. The material handling zone 3 is a normal temperature zone. The temperature shock test chamber body 1 simulates extreme temperature environments through independent high-temperature zone 2 and low-temperature zone 4, transferring the workpiece between the two chambers to trigger changes in material thermal stress. Its cascade refrigeration system and PID temperature control algorithm ensure that the temperature recovery time meets the standard. Combined with multi-layer magnetic fluid sealing technology and pressure difference balance system, it effectively suppresses the leakage of hot and cold air. The entire process is intelligently controlled by PLC, realizing multi-segment programming, real-time monitoring, and safety protection (emergency stop device), accurately verifying the reliability, durability, and failure threshold of electronic components, aerospace devices, etc. under severe temperature changes.

[0036] In one embodiment, the lifting mechanism 5 includes a motor 501, which is fixedly connected to the top of the temperature shock test chamber body 1. The output shaft of the motor 501 is fixedly connected to a lead screw 502, which is rotatably connected inside the temperature shock test chamber body 1. A lifting frame 503 is threadedly connected to the surface of the lead screw 502, and the lifting frame 503 is slidably connected inside the temperature shock test chamber body 1.

[0037] The motor 501 drives the lead screw 502 to rotate, which in turn drives the lifting frame 503 to move up and down within the temperature shock test chamber 1, allowing the lifting frame 503 to switch between the high temperature zone 2, the material handling zone 3, and the low temperature zone 4.

[0038] In one embodiment, the isolation mechanism 6 includes an isolation frame 601, which is fixedly connected to one end of the lifting frame 503. An upper extension column 602 is slidably connected to one end of the isolation frame 601, and an upper extension partition 603 is fixedly connected to one end of the upper extension column 602. A lower extension column 604 is slidably connected to the other end of the isolation frame 601, and a lower extension partition 605 is fixedly connected to one end of the lower extension column 604. A plurality of springs 606 are fixedly connected to one end of both the upper extension column 602 and the lower extension column 604. One end of each spring 606 is fixedly connected inside the isolation frame 601. Sealing rings 607 are fixedly installed below the upper extension partition 603 and above the lower extension partition 605, respectively. The upper extension partition 603 and the lower extension partition 605 are slidably connected inside the high-temperature zone 2 and the low-temperature zone 4.

[0039] When the isolation frame 601 is located in the material handling area 3, it isolates the material handling area 3 from the low-temperature area 4 and the high-temperature area 2. The lifting frame 503 drives the isolation frame 601 to switch between the high-temperature area 2, the material handling area 3, and the low-temperature area 4. When the isolation frame 601 moves to the high-temperature area 2, it isolates the high-temperature area 2 from the material handling area 3. The isolation frame 601 causes the lower extension partition 605 and the lower extension column 604 to compress the spring 606, causing the lower extension column 604 to retract into the isolation frame 601. The isolation frame 601 then causes the upper extension column 602 and the upper extension partition 603 to contact the area between the material handling area 3 and the low-temperature area 4. The sealing ring 607 below the upper extension partition 603 then controls the material handling... The material handling area 3 and the low-temperature area 4 are sealed and isolated. When the isolation frame 601 moves to the low-temperature area 4, the isolation frame 601 isolates the low-temperature area 4 from the material handling area 3. The isolation frame 601 drives the upper extension column 602 and the upper extension partition 603 to compress the spring 606, so that the upper extension column 602 retracts into the isolation frame 601. The isolation frame 601 drives the lower extension column 604 and the lower extension partition 605 to contact the material handling area 3 and the high-temperature area 2. The sealing ring 607 above the lower extension partition 605 seals and isolates the material handling area 3 and the high-temperature area 2, thus completing the sealing between the high-temperature area 2, the material handling area 3 and the low-temperature area 4 when the workpiece switches between the high-temperature area 2, the material handling area 3 and the low-temperature area 4.

[0040] In addition, the upper extension partition 603, extension partition 605 and isolation frame 601 are all heat and cold insulation materials, which facilitates the separation between the high temperature zone 2, the material handling zone 3 and the low temperature zone 4. The isolation frame 601 is slidably connected between the high temperature zone 2, the material handling zone 3 and the low temperature zone 4, and one side is slidably connected to the surface of the lead screw 502.

[0041] In one embodiment, the above-mentioned picking mechanism 7 includes a sliding plate 701, which is slidably connected inside the isolation frame 601. Springs 702 are fixedly connected to both sides of the sliding plate 701, and one end of the springs 702 is fixedly connected inside the isolation frame 601.

[0042] Pull one end of the sliding plate 701 to compress the second spring 702, causing the sliding plate 701 to slide inside the isolation frame 601. Place the workpiece on the surface of the rotating mechanism 8 above the sliding plate 701, and then reset the sliding plate 701. The second spring 702 drives the sliding plate 701 to be limited.

[0043] In one embodiment, the rotating mechanism 8 includes a turntable 801, which is rotatably connected to the surface of a sliding plate 701. A gear 802 is fixedly connected to one end of the turntable 801, and a rack 803 meshes with the surface of the gear 802. The rack 803 is slidably connected inside the isolation frame 601. A second motor 804 is fixedly installed on one side of the isolation frame 601. An eccentric disk 805 is fixedly connected to the output shaft of the second motor 804. A reciprocating rod 806 is rotatably connected to the eccentric end of the eccentric disk 805, and one end of the reciprocating rod 806 is fixedly connected to one end of the rack 803.

[0044] The eccentric disk 805 is driven to rotate by the motor 804, which in turn drives the reciprocating rod 806 to slide. The reciprocating rod 806 drives the rack 803 to reciprocate inside the isolation frame 601. The rack 803 drives the gear 802 to rotate back and forth, which in turn drives the turntable 801 to rotate on the surface of the sliding plate 701. The turntable 801 rotates slowly back and forth, causing the workpiece located on the surface of the turntable 801 to rotate slowly back and forth. This allows the workpiece to be heated or cooled evenly within the high-temperature zone 2 and the low-temperature zone 4, preventing the local temperature of the workpiece from being too high or too low.

[0045] In addition, the sliding plate 701 is limited by the second spring 702, so that the sliding plate 701 drives the gear 802 to keep in contact with the surface of the rack 803.

[0046] Through the above technical solution, 1. By pulling one end of the sliding plate 701, the sliding plate 701 compresses the second spring 702, causing the sliding plate 701 to slide inside the isolation frame 601, placing the workpiece on the surface of the turntable 801, and then resetting the sliding plate 701. The second spring 702 drives the sliding plate 701 to be limited. When the isolation frame 601 is located in the material handling area 3, the isolation frame 601 isolates the material handling area 3 from the low temperature area 4 and the high temperature area 2. The motor 501 drives the lead screw 502 to rotate, causing the lead screw 502 to drive the lifting frame 503 to rise and fall within the temperature shock test chamber body 1. The lifting frame 503 drives the isolation frame 601 to switch between the high temperature area 2, the material handling area 3, and the low temperature area 4. When the isolation frame 601 moves to the high temperature area 2, the isolation frame 601... The high-temperature zone 2 is isolated from the material handling zone 3. The upper extension column 602 and the upper extension partition 603 are driven by the isolation frame 601 to contact the material handling zone 3 and the low-temperature zone 4. When the isolation frame 601 moves to the low-temperature zone 4, it isolates the low-temperature zone 4 from the material handling zone 3. The lower extension column 604 and the lower extension partition 605 are driven by the isolation frame 601 to contact the material handling zone 3 and the high-temperature zone 2. This completes the sealing between the high-temperature zone 2, the material handling zone 3 and the low-temperature zone 4 when the workpiece is switched between the high-temperature zone 2, the material handling zone 3 and the low-temperature zone 4. After completion, the workpiece is moved to the material handling zone 3, and one end of the sliding plate 701 is pulled to compress the second spring 702, so that the sliding plate 701 slides inside the isolation frame 601 and the workpiece can be taken out.

[0047] 2. The eccentric disk 805 is driven to rotate by the motor 804, which in turn drives the reciprocating rod 806 to slide. The reciprocating rod 806 drives the rack 803 to reciprocate inside the isolation frame 601. The rack 803 drives the gear 802 to rotate back and forth, which in turn drives the turntable 801 to rotate on the surface of the sliding plate 701. The turntable 801 rotates slowly back and forth, causing the workpiece located on the surface of the turntable 801 to rotate slowly back and forth. This allows the workpiece to be heated or cooled evenly within the high-temperature zone 2 and the low-temperature zone 4, preventing the local temperature of the workpiece from being too high or too low.
