Description

Technical Field

[0001] The present invention relates to the technical field of testing equipment, and in particular to a high-temperature aging testing device and a testing method. Background Art

[0002] High-temperature aging testing is a reliability testing method that examines the performance of electronic components, new energy equipment, automotive parts, polymer materials and other products under high-temperature conditions. In particular, for core components such as circuit boards that are frequently used in high-end fields such as aerospace, new energy vehicles, and semiconductors, their performance degradation under extreme temperature conditions directly affects their service life and safety. Therefore, high-temperature aging testing, as a key means of simulating long-term operation of products under high-temperature conditions, has become an indispensable part of product research and development, quality control and standard certification.

[0003] The traditional high-temperature aging test method is to place the product in a sealed container and heat the inside of the container through a circulating high-temperature airflow, so that the product is in a high-temperature environment. After the product is placed for a specified time, it is taken out and tested to see if it can be used normally. When using this test method, the product is generally supported by a tray or several horizontal bars arranged side by side, that is, the product is generally in a stationary state. Since the high-temperature airflow in the equipment generally flows from bottom to top when circulating, when a tray is used, the high-temperature airflow cannot contact the bottom of the product, and the airflow cannot blow down to the upper surface of the product, resulting in uneven heating temperature of the product. When using the horizontal bar method, although the bottom of the product can be directly in contact with the airflow for heating, it still cannot heat the upper part of the product, which also causes uneven heating of the product and affects the test accuracy.

DETAILED DESCRIPTION

[0018] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0019] like Figures 1 to 8As shown, a high temperature aging test device of the present invention includes an outer box 100 and an inner liner 200 installed inside the outer box 100. The inner liner 200 has an opening for the product to enter and exit. A driving part 202 for driving the product to move is provided in the inner liner 200. The driving unit 202 includes a driving disc 203, a connecting shaft 204 coaxially mounted on the driving disc 203, and a crossbeam 205 mounted at the end of the connecting shaft 204. Two vertical beams 206 are disposed opposite each other on the crossbeam 205, and the two vertical beams 206 are located on either side of the axis of the driving disc 203. A plurality of clamping rollers 207 are rotatably mounted on each vertical beam 206. The driving disc 203 is used to drive the product to turn over, and the clamping rollers 207 on the two vertical beams 206 are used to clamp the product. In the present invention, the inner liner 200 is an independent container, which is installed inside the outer box 100. By opening the door 101 on the outer box 100, the product can be placed into the inner liner 200 through the opening on the inner liner 200, or the product in the inner liner 200 can be taken out. This independently arranged inner liner 200 can be designed to have a detachable structure with the outer box 100, which is convenient for cleaning, maintenance and replacement of the inner liner 200, and convenient for replacing inner liner 200 of different specifications, materials and heating methods according to different testing requirements. In addition, multifunctional modules such as humidity control and gas circulation can be integrated into the inner liner 200, and the outer box 100 can provide physical isolation, electromagnetic shielding and other anti-interference effects for the inner liner 200 during manufacturing. The driving disc 203 in the driving unit 202 is the main rotating component, which can drive the various structures on it to rotate, thereby driving the product to rotate. The product can rotate in any direction, such as vertically or horizontally, so that the product can come into contact with the high-temperature airflow flowing in the inner container 200 and achieve a comprehensive heating effect on the product. It should be noted that, since the high-temperature airflow in the inner container 200 can flow in any direction other than from bottom to top, such as horizontal flow, from top to bottom flow, or oblique flow, the axial direction of the driving disk 203 can be adjusted to meet different flow directions, so that the product's flipping axis is perpendicular to or at a certain angle to the flow direction of the airflow. The horizontal beam 205 and vertical beam 206 on the driving part 202 are mainly used to provide installation positions for the clamping rollers 207. The clamping rollers 207 can be divided into two groups to facilitate clamping of both sides of the product. When assembling the product, it can be directly inserted between the clamping rollers 207 on the two vertical beams 206. During use, the door 101 on the outer box 100 is opened, and the product is loaded between the clamping rollers 207 on the driving part 202 in the inner liner 200 through the opening on the inner liner 200. The clamping rollers 207 continue to clamp and fix the product. The door 101 is closed, and the high-temperature airflow circulating in the inner liner 200 can heat the product in the inner liner 200. At the same time, the rotation of the driving disk 203 drives the product to flip, so that different positions of the product can contact the airflow, achieving a uniform heating effect of the airflow on the product, thereby improving the accuracy of the test; By turning the product over during the high-temperature aging test, the high-temperature airflow in the device can contact different positions of the product, achieving a comprehensive and uniform heating effect on the product, and avoiding the impact of uneven heating on the product on the test accuracy. The combination of the outer box 100 and the inner liner 200 facilitates the cleaning, maintenance and replacement of the inner liner 200, and facilitates the replacement of inner liners 200 of different specifications, materials and heating methods according to different test requirements. In some embodiments, in order to make the driving part 202 move more dynamically, two driving parts 202 can be arranged opposite to each other in the inner container 200, such as Figure 4 As shown, the two ends of the clamping roller 207 are respectively connected to the vertical beams 206 on the two driving parts 202, thereby improving the structural strength and operation stability.

[0020] Optimizing the above implementation, the clamping roller 207 reciprocates on the vertical beam 206, and the clamping roller 207 drives the product to reciprocate on the driving disk 203; When the clamping roller 207 contacts the product, it blocks part of the product, preventing the blocked portion from contacting the high-temperature airflow. This also causes uneven heating of the product. To solve this problem, the clamping roller 207 can be rotated on the vertical beam 206. The rotation of the clamping roller 207 allows the product to move along the radial direction of the driving disk 203 on the driving disk 203, thereby revealing the blocked portion of the product and facilitating comprehensive heating of the product by the high-temperature airflow. It should be noted that in order to keep the product on the clamping roller 207 at all times, the clamping roller 207 can be rotated in the forward direction for a specified number of turns and then rotated in the reverse direction, thereby causing the product to reciprocate on the driving disk 203.

[0021] During the assembly or disassembly process of the product, if the product is inserted into the gap between the clamping rollers 207 on two adjacent vertical beams 206, the installation direction of the product and the orientation of the vertical beams 206 need to be kept in the specified position, and the insertion or disassembly of the product will cause relative friction between it and the clamping rollers 207. Therefore, although the above method can achieve the clamping of the product, its effect is still not ideal. To solve this problem, the following method can be used: Figure 8 In the manner shown, one vertical beam 206 on the crossbeam 205 is fixedly connected to the crossbeam 205, and the other vertical beam 206 is detachably connected to the crossbeam 205 by bolts 208 or a clamping method; when it is necessary to clamp a product, it is only necessary to remove one vertical beam 206 on the crossbeam 205 to directly place the product on the crossbeam 205, and then reassemble the removed vertical beam 206 onto the crossbeam 205, thereby completing the clamping work of the clamping roller 207. This operation method is simpler and does not limit the position of the vertical beam 206 and the direction of the product.

[0022] Optimized on the above implementation, such as Figures 5 and 6 As shown, the inner container 200 further includes a pushing unit and a guiding unit. The pushing unit includes a screw 209 rotatably mounted on the inner wall of the inner container 200. A screw sleeve 210 is provided on the screw 209. The driving disk 203 is rotatably disposed on the screw sleeve 210. The guiding unit is used to guide the screw sleeve 210. Since the product testing position is located inside the inner liner 200, the staff need to put their hands deep into the inner liner 200 to operate when installing or removing the product. This can easily block the workers' line of sight, making their operation extremely inconvenient. If the driving part 202 is actively moved to the opening position of the inner liner 200, it will be convenient for the workers to operate. To achieve this goal, the external motor can be used to drive the rotating screw 209 so that the screw 209 pushes the sleeve 210 to move, and the sleeve 210 drives the driving disk 203 to move, thereby realizing the adjustment of the position of the vertical beam 206 and the clamping roller 207. The guide unit can guide the sleeve 210 to prevent it from rotating synchronously with the screw 209.

[0023] Optimized on the above implementation, such as Figures 5 and 6As shown, the guide unit includes a guide post 212 coaxially arranged in the liner 200 with the screw 209, a guide sleeve 213 is slidably provided on the guide post 212, and a connecting portion 211 is provided on the guide sleeve 213, and the screw sleeve 210 passes through the connecting portion 211 and is connected to each other; the connecting portion 211 can connect the guide sleeve 213 and the screw sleeve 210, so that when the screw sleeve 210 moves, it can drive the guide sleeve 213 to slide on the guide post 212 through the connecting portion 211, thereby achieving the guiding work of the screw sleeve 210; since the relative position between the screw 209 and the guide post 212 is fixed, the guide sleeve 213 and the connecting portion 211 can be rotatably connected or directly fixedly connected, which can achieve the purpose of guiding; the specific structure of the connecting portion 211 can include two ear plates on the upper side, a vertical plate in the middle and a barrel on the lower side, the ear plates are connected to the guide sleeve 213, the vertical plate connects the ear plates and the barrel, and the barrel is sleeved on the outer wall of the screw sleeve 210.

[0024] Optimized on the above implementation, such as Figure 6 As shown, a plurality of sliding grooves parallel to the axis of the guide column 212 are provided on the outer wall of the guide column 212, and a plurality of sliding edges cooperating with the sliding grooves are provided in the guide sleeve 213; The guide post 212 rotates in the inner container 200, and the guide sleeve 213 rotates on the connecting portion 211. The connecting portion 211 is provided with a transmission structure for transmitting the rotation of the guide sleeve 213 to the driving disk 203; The sliding groove on the guide column 212 and the sliding edge in the guide sleeve 213 can ensure that the guide sleeve 213 slides smoothly in the axial direction of the guide column 212, and when the guide column 212 rotates, it will drive the guide sleeve 213 to rotate synchronously, thereby achieving the purpose of guidance and the purpose of driving the guide sleeve 213 to rotate. The rotation and transmission structure of the guide sleeve 213 can be used to transmit power to the drive disk 203, thereby driving the drive disk 203 to rotate.

[0025] Optimized to the above implementation, such as Figure 6 and Figure 10 As shown, the transmission structure includes a bevel gear 214 provided on a guide sleeve 213 and a bevel gear column 215 that meshes with the bevel gear 214 for transmission. The bevel gear column 215 is rotatably mounted on the connecting portion 211. A transmission wheel 216 is provided at the end of the bevel gear column 215, and the transmission wheel 216 is in transmission connection with the drive disc 203. A movable plate 221 is provided between the two vertical beams 206. The side walls of the movable plate 221 are transmission-connected to the clamping rollers 207. A slider 220 is provided on the movable plate 221 and is slidably connected to the crossbeam 205. A second ring 219 is sleeved on the outer side of the connecting shaft 204. The second ring 219 is connected to the slider 220. A first ring 218 is rotatably sleeved on the second ring 219. The first ring 218 is eccentrically connected to the transmission wheel 216 via a rod 217. In the present invention, the rotation of the guide sleeve 213 can be transmitted to the transmission wheel 216 through the bevel gear 1 214 and the bevel gear column 215, thereby causing the transmission wheel 216 to directly drive the drive plate 203 to rotate. The rotation of the transmission wheel 216 drives the ring body 1 218 to reciprocate through the eccentrically arranged rod body 217, thereby driving the slider 220 to reciprocate on the beam 205 through the ring body 219. The slider 220 drives each clamping roller 207 to reciprocate through the movable plate 221. In this way, the dual motion effect of product flipping and reciprocating motion is achieved by utilizing the single rotational motion of the guide column 212. Since the driving disk 203 needs to rotate, the driving disk 203 drives the slider 220 and the second ring body 219 to rotate, thereby causing the second ring body 219 and the first ring body 218 to perform relative rotational motion.

[0026] Optimized to the above implementation, such as Figure 6 As shown, a moving body 222 that moves along the axis of the lead screw 209 is provided on the connecting portion 211, and the driving disk 203 is rotatably mounted on the moving body 222; The rod 217 is a structure with elastic expansion and contraction function; When the driving disc 203 moves toward the opening of the inner liner 200, since the screw sleeve 210 can only move to the end of the lead screw 209, the driving disc 203 and the product thereon can only remain in the inner liner 200 and cannot pass through the opening of the inner liner 200. This causes the worker to reach into the inner liner 200 to operate. By providing the movable body 222, when the screw sleeve 210 moves to the end of its stroke, the movable body 222 can be pushed to move on the connecting portion 211, so that the movable body 222 drives the product to pass through the opening of the inner liner 200, thereby further increasing the movable range of the driving portion 202 and facilitating the operation of the worker. The lever 217 is in a position perpendicular to the lever 216 and the lever 218 is in a position perpendicular to the lever 216. ... and the lever 218 is in a position perpendicular to the lever 216 and the lever 218 is in a position perpendicular to the lever 216 and the lever 218 is in a position perpendicular to the lever 21 In order to ensure that the driving disc 203 can still transmit power to the transmission wheel 216 when the driving disc 203 returns to its initial position, the transmission wheel 216 and the driving disc 203 can both be configured as gear structures to improve transmission stability.

[0027] Optimized on the above implementation, such as Figure 6 and Figure 9 As shown, the screw sleeve 210 is rotatably connected to the connecting portion 211. A circular groove is provided on the outer wall of the screw sleeve 210. The circular groove is located inside the connecting portion 211. A torsion spring 224 for connecting the screw sleeve 210 and the connecting portion 211 is provided in the circular groove. A second helical gear 223 is provided on the outer wall of the screw sleeve 210, and a helical gear area for use with the second helical gear 223 is provided on the side wall of the moving body 222; In the present invention, the setting of the torsion spring 224 can keep the screw sleeve 210 and the connecting part 211 in a relatively stable state. When the screw sleeve 210 moves to the end position of the screw 209, the continuous rotation of the screw 209 will drive the screw sleeve 210 to rotate synchronously. At this time, the screw sleeve 210 rotates relative to the connecting part 211, and the screw sleeve 210 drives the upper bevel gear 223 to rotate. Since the bevel gear 223 and the moving body 222 are engaged with the bevel teeth, the bevel gear 223 can push the moving body 222 to move horizontally on the connecting part 211, thereby providing power for the movement of the moving body 222.

[0028] A high-temperature aging test method, using the above-mentioned high-temperature aging test device, includes the following steps: Move the driving unit 202 to the opening position of the inner container 200; Open the door 101 on the outer box 100 and install the product on the driving part 202 through the opening of the inner container 200; Move the driving unit 202 to the inner side of the inner container 200 and close the door 101 to block the opening on the outer side of the outer box 100; The heating structure 102 on the outer box 100 is used to heat the inner space of the inner container 200 to achieve high temperature aging test of the product; After the product test is completed, the product is moved back into the opening of the outer box 100 by the driving unit 202; The open end of the inner side of the inner liner 200 is sealed to separate the inner liner 200 from the product; Open the door 101, remove the product from the driving part 202 at the opening position and reinstall the next product on the driving part 202; Close the door 101 and seal the opening on the outside of the outer box 100; Stop blocking the open end of the inner side of the inner liner 200 and move the inner liner 200 to the initial position; The product is repeatedly tested using the original high temperature environment in the inner tank 200.

[0029] In the above method, since both ends of the opening of the liner 200 are closed, a channel 201 can be set on the opening so that the product can be temporarily stored in the channel 201; for the blocking work of one end of the opening in the liner 200, the following method can be used: Figure 3 The shields 300 and cylinders 301 are shown. The cylinders 301 drive the shields 300 to move and connect with each other, thereby achieving the blocking work. By using the above-mentioned testing method, the inner tank 200 can always be kept at a high temperature, thereby avoiding energy loss caused by temperature loss, improving energy utilization, and eliminating the need to wait for the inner tank 200 to cool to room temperature before taking the product out, thus avoiding wasting waiting time.

[0030] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
