Description

Technical Field

[0001] This invention relates to the field of aging testing technology, and in particular to an aging testing device for an industrial controller. Background Technology

[0002] Industrial controllers are core equipment in industrial automation systems, responsible for monitoring, controlling, and protecting the production process. Their reliability directly affects the stable operation of the entire production line. To ensure the long-term stability of industrial controllers under harsh operating conditions, they must undergo whole-machine aging tests before leaving the factory. This test simulates accelerated stress environments such as high and low temperature cycles and alternating damp heat to comprehensively screen the controller's circuit performance and assess its lifespan. Currently, commonly used whole-machine aging test equipment mainly consists of a constant temperature and humidity test chamber, test fixtures, and a conveyor line. Controllers to be tested are placed in batches inside the test chamber manually or by robotic arms, and then removed uniformly after completing the specified test cycle, achieving batch reliability verification.

[0003] For example, a testing device for anti-aging of a vehicle body controller disclosed in Chinese Patent Publication No. (CN119575039A) includes a testing body; the left side of the testing body houses a vehicle body controller test box for anti-aging testing, a data acquisition module, a power supply, and a load motor; the data acquisition module is connected to a wiring harness on the right side of the vehicle body controller test box for monitoring the voltage and current of the wiring harness; a lower main locking seat for clamping one end of the wiring harness is installed on the testing body to the right of the data acquisition module; and first clamping plates for adaptive automatic clamping of the vehicle body controller are symmetrically installed above the placement platform. This testing device for anti-aging of the vehicle body controller prevents one end of the wiring harness from detaching from the vehicle body controller, thus facilitating the entire testing device to perform anti-aging operations on the vehicle body controller effectively without affecting the testing operation or the accuracy of the test.

[0004] However, existing testing equipment has significant drawbacks in the loading and unloading process: the controller needs to keep the cabinet door open for an extended period when entering and exiting the test chamber, causing drastic exchanges between the internal temperature and humidity environment and the external environment. This not only disrupts the stability and uniformity of the testing environment, leading to data deviations and a surge in energy consumption, but more seriously, frequent temperature fluctuations can interfere with the aging process of sensitive components, reducing the accuracy and repeatability of test results. Furthermore, traditional manual or simple robotic loading and unloading methods cannot achieve precise synchronization with the opening and closing of the cabinet door, resulting in low operational efficiency and failing to meet the cycle time requirements of modern production lines for automated and continuous testing. Summary of the Invention

[0005] In view of the problems existing in the above or prior art, the present invention is proposed.

A docking block is slidably installed inside each of the two sets of adjustment ports. The back of each of the two sets of docking blocks is connected to the two sets of slide strips respectively.

[0010] In a preferred embodiment of the industrial controller aging test device of the present invention, the top of the suspension bracket is provided with an embedding groove, and the conveyor belt is embedded in the embedding groove.

[0011] In a preferred embodiment of the industrial controller aging test device of the present invention, the top of the test host is provided with an outlet corresponding to the position of the door panel, and a sealing strip is fixedly provided on the top of the door panel.

[0012] In a preferred embodiment of the industrial controller aging test device of the present invention, the lifting component includes partitions respectively fixedly disposed inside the two sets of vertical frames. A lead screw is rotatably disposed between the left partition and the side opposite to the left vertical frame. A sliding rod is fixedly disposed between the right partition and the side opposite to the right vertical frame. A lifting plate is threaded on the outer side of the lead screw. A first motor is fixedly disposed at the bottom of the left partition, and the output end of the first motor is connected to the lead screw.

[0013] As a preferred embodiment of the industrial controller whole machine aging test device of the present invention, the left side of the lifting plate is provided with a screw hole for threaded connection with the lead screw, and the right side of the lifting plate is provided with a sliding hole adapted to the size of the sliding rod.

[0014] As a preferred embodiment of the industrial controller whole machine aging test device of the present invention, the translation component includes two sets of connecting frames fixedly disposed on the top of the lifting plate. Two sets of rotating shafts are rotatably disposed inside the two sets of connecting frames. Pulleys are fixedly disposed on the outer side of each of the two sets of rotating shafts. A transmission belt is disposed on the outer side of each of the two sets of pulleys.

[0019] The beneficial effects of this invention are as follows: By setting up a door opening component and a lifting component in coordination, when the lifting component drives the translation component and the clamped controller to rise, the door opening component simultaneously pushes the test host cabinet door open, allowing the controller to be precisely translated to the test position. After clamping is completed, the lifting component descends, and the cabinet door automatically closes. This structure strictly limits the cabinet door opening time to within the necessary action cycle of the controller's pick-up and put-down, thereby avoiding the drastic exchange of temperature and humidity inside and outside the chamber caused by prolonged door opening in traditional methods. This ensures that the test environment remains stable and uniform over a long period of time, significantly reduces the interference of temperature fluctuations on the aging process of sensitive components, thereby improving the accuracy and repeatability of test data and effectively reducing energy consumption.

[0020] Another beneficial effect of this invention is that by modularly cooperating with the feeding assembly, suspension bracket, and conveyor belt, an automated transfer channel is constructed between the conveyor belt and the testing host. The crossbeam, vertical frame, lifting component, and translation component are sequentially connected to form a stable spatial displacement mechanism. With the help of electric push rods and pneumatic suction cups, the controller can achieve adaptive clamping. The entire transfer process can achieve continuous operation without manual intervention. This solves the problems of low efficiency and mismatched cycle time of traditional manual or simple robotic arms for loading and unloading. Furthermore, the orderly cooperation between the structures realizes the automation, continuous and cycle-based production of aging tests, significantly improving testing efficiency and capacity, and fully meeting the stringent requirements of modern production lines for the efficient and stable operation of testing equipment.

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1, referring to Figures 1-7This is the first embodiment of the present invention. This embodiment provides an industrial controller whole machine aging test device, which can realize the automated transfer between the conveyor belt 4 and the test host 1. Through the linkage of the lifting component 33 and the door opening component 35, the opening time of the cabinet door is strictly limited within the controller pick-up and put-down action cycle, effectively avoiding temperature and humidity fluctuations in the test environment. It includes the test host 1, a suspension bracket 2 set on the front of the test host 1, a feeding component 3 set inside the suspension bracket 2, and a conveyor belt 4 fixedly set on the top of the suspension bracket 2.

[0034] It should be noted that the test host 1 is an aging test chamber with a built-in temperature and humidity control system. Its top has an outlet corresponding to the position of the door panel 356. The interior is equipped with test stations and electrical connection interfaces for accelerating aging tests such as high and low temperature cycling and damp heat alternation on industrial controllers that enter the chamber.

[0035] Furthermore, the feeding assembly 3 includes a crossbeam 31 fixedly installed inside the suspension bracket 2. Two sets of vertical frames 32 are fixedly installed on the top of the crossbeam 31. Lifting components 33 are installed inside the two sets of vertical frames 32. A translation component 34 is installed on the top of the lifting component 33. Door opening components 35 are installed on the left and right sides of the lifting component 33.

[0036] Furthermore, the door opening component 35 includes connecting plates 351 fixedly installed on the left and right sides of the lifting component 33, and a top rod 352 fixedly installed on the top of each of the two sets of connecting plates 351. The test host 1 has a test cavity 353 inside, and sliding grooves 354 are opened on the inner walls of the left and right sides of the test cavity 353. Sliding strips 355 are slidably installed inside each of the two sets of sliding grooves 354. A door panel 356 is fixedly installed between the opposite sides of the two sets of sliding strips 355. The front of the test host 1 has adjustment ports 359 corresponding to the positions of the two sets of sliding grooves 354. A docking block 357 is slidably installed inside each of the two sets of adjustment ports 359. The back of the two sets of docking blocks 357 is connected to the two sets of sliding strips 355 respectively.

[0037] During use, after clamping the industrial controller, the lifting component 33 drives the lifting plate 334 to rise and reset. During this process, the top rod 352 of the door opening component 35 pushes the docking block 357 simultaneously, causing the door panel 356 to open upward along the slide bar 355. At this time, the second motor 348 drives the rotating shaft 342 and the drive gear 3412 to rotate, meshing with the rack 346 to drive the translation plate 347 to move the clamped controller horizontally along the limit groove, passing through the exit at the top of the test host 1 and entering the test chamber 353. After clamping is completed, the lifting component 33 descends and resets, the top rod 352 disengages from the docking block 357, and the door panel 356 closes under its own weight. The sealing strip 358 ensures the sealing performance.

[0038] In summary, the controller's loading and unloading and the cabinet door's opening and closing are synchronized through mechanical linkage throughout the entire process, strictly limiting the door opening time to within the lifting and lateral movement cycle, thus avoiding fluctuations in the temperature and humidity of the test environment.

[0039] Example 2, refer to Figures 1-7 This is the second embodiment of the present invention, which differs from the first embodiment in that it also includes an automated loading and unloading test operation for the industrial controller. In the previous embodiment, the industrial controller aging test device includes a test host 1, a suspension bracket 2 disposed on the front of the test host 1, a feeding assembly 3 disposed inside the suspension bracket 2, and a conveyor belt 4 fixedly disposed on the top of the suspension bracket 2.

[0040] Furthermore, the feeding assembly 3 includes a crossbeam 31 fixedly installed inside the suspension bracket 2. Two sets of vertical frames 32 are fixedly installed on the top of the crossbeam 31. Lifting components 33 are installed inside the two sets of vertical frames 32. A translation component 34 is installed on the top of the lifting component 33. Door opening components 35 are installed on the left and right sides of the lifting component 33.

[0041] Furthermore, the door opening component 35 includes connecting plates 351 fixedly installed on the left and right sides of the lifting component 33, and a top rod 352 fixedly installed on the top of each of the two sets of connecting plates 351. The test host 1 has a test cavity 353 inside, and sliding grooves 354 are opened on the inner walls of the left and right sides of the test cavity 353. Sliding strips 355 are slidably installed inside each of the two sets of sliding grooves 354. A door panel 356 is fixedly installed between the opposite sides of the two sets of sliding strips 355. The front of the test host 1 has adjustment ports 359 corresponding to the positions of the two sets of sliding grooves 354. A docking block 357 is slidably installed inside each of the two sets of adjustment ports 359. The back of the two sets of docking blocks 357 is connected to the two sets of sliding strips 355 respectively.

[0042] Furthermore, the top of the suspension bracket 2 is provided with an embedding groove, and the conveyor belt 4 is embedded inside the embedding groove.

[0043] Furthermore, the top of the test host 1 is provided with an outlet corresponding to the position of the door panel 356, and a sealing strip 358 is fixedly installed on the top of the door panel 356.

[0044] Furthermore, the lifting component 33 includes partitions 331 that are fixedly installed inside the two sets of vertical frames 32 respectively. A lead screw 332 is rotatably installed between the left partition 331 and the side opposite to the left vertical frame 32. A slide rod 333 is fixedly installed between the right partition 331 and the side opposite to the right vertical frame 32. A lifting plate 334 is threaded on the outer side of the lead screw 332. A first motor 335 is fixedly installed at the bottom of the left partition 331. The output end of the first motor 335 is connected to the lead screw 332.

[0045] Furthermore, the left side of the lifting plate 334 is provided with a screw hole for threaded connection with the lead screw 332, and the right side of the lifting plate 334 is provided with a sliding hole that matches the size of the slide rod 333.

[0046] Specifically, after the industrial controller to be inspected is conveyed by the conveyor belt 4 to the embedded slot station at the top of the suspension bracket 2, the first motor 335 of the lifting component 33 drives the lead screw 332 to rotate, which drives the lifting plate 334 to descend vertically along the slide bar 333, so that the translation component 34 is adjusted as a whole to the clamping position that matches the height of the controller to be inspected.

[0047] Furthermore, the translation component 34 includes two sets of connecting frames 341 fixedly mounted on the top of the lifting plate 334. Two sets of rotating shafts 342 are rotatably mounted inside the two sets of connecting frames 341. Pulleys 343 are fixedly mounted on the outer side of each of the two sets of rotating shafts 342. A transmission belt 344 is mounted on the outer side of each of the two sets of pulleys 343. A drive gear 3412 is fixedly mounted on the outer side of each of the two sets of rotating shafts 342 and below the pulleys 343. A placement slot 345 is opened on the opposite side of each of the two sets of connecting frames 341. A rack 346 is slidably mounted inside each of the two sets of placement slots 345. A translation plate 347 is fixedly mounted on the side of each of the two sets of racks 346 that are close to each other.

[0048] Furthermore, the two sets of racks 346 are respectively meshed with the left and right drive gears 3412, and the top of the two sets of connecting frames 341 are fixedly equipped with a second motor 348, and the two sets of second motors 348 are respectively connected to the left and right rotating shafts 342.

[0049] Furthermore, the top of the lifting plate 334 is provided with a limiting groove corresponding to the position of the two sets of translation plates 347, and the inside of the two sets of limiting grooves is slidably provided with limiting strips, and the two sets of limiting strips are respectively connected to the bottom of the two sets of translation plates 347.

[0050] Specifically, the translation component 34 adopts a segmented collaborative drive structure with dual drive gears 3412, which includes: two sets of connecting frames 341 respectively setting rotating shafts 342 and drive gears 3412, and two sets of second motors 348 independently driving the rotating shafts 342 and drive gears 3412 on the left and right sides; when the translation plate 347 is in the center position, its bottom two sets of racks 346 mesh with the drive gears 3412 on the front and rear sides simultaneously, forming a dual-point synchronous drive to ensure the smoothness of the initial translation movement; when the translation plate 347 moves forward, its rear rack 346 gradually disengages from the rear drive gear 3412, while the front rack... The rack 346 continues to mesh with the front drive gear 3412, and the front drive gear 3412 alone drives the translation plate 347 to continue moving forward to the designated test station. When translating backward and resetting, the driving logic is reversed. The translation plate 347 is first driven by the front drive gear 3412, and then the rear rack 346 re-meshes with the rear drive gear 3412 to achieve dual-drive relay transmission, and finally returns to the center position. This segmented drive design not only ensures full coverage of the translation stroke, but also reduces the load on a single set of drive gears 3412 through relay transmission, thereby improving the stability and positioning accuracy of the translation process.

[0051] Furthermore, the translation component 34 also includes electric push rods 349 that are fixedly installed on the opposite side of the two sets of translation plates 347. Each set of electric push rods 349 has a clamping plate 3410 fixedly installed at its output end. Each set of clamping plates 3410 has a number of pneumatic suction cups 3411 fixedly installed on the side of the two sets of clamping plates 3410 that are close to each other.

[0052] It should be noted that the pneumatic suction cup 3411 achieves non-destructive clamping of the industrial controller under inspection through negative pressure adsorption, ensuring that the controller maintains a stable posture during lifting and translation, avoiding surface damage or stress deformation caused by rigid clamping. The pneumatic suction cup 3411 is equipped with an independent pneumatic control system, including a vacuum generator, an electromagnetic reversing valve, a pressure sensor and connecting pipelines. This pneumatic control system is electrically connected to the central controller of the test host 1, and can automatically adjust the adsorption pressure according to the size and weight of the controller, and trigger an alarm signal when the clamping is abnormal.

[0053] Furthermore, the top rod 352 is L-shaped, and the bottom of the mating block 357 has a mating groove corresponding to the position of the top rod 352.

[0054] In use, after the industrial controller to be inspected is conveyed by the conveyor belt 4 to the embedded slot at the top of the suspension bracket 2, the first motor 335 of the lifting component 33 drives the lead screw 332 to rotate, causing the lifting plate 334 to descend vertically along the slide bar 333, so that the translation component 34 is adjusted to a clamping position that matches the height of the controller to be inspected; then the electric push rod 349 in the translation component 34 drives the clamping plate 3410 to extend, and the controller is attracted and fixed by the pneumatic suction cup 3411. After clamping is completed, the lifting component 33 drives the lifting plate 334 to rise and reset. During this process, the L-shaped top rod of the door opening component 35... 352 synchronously pushes the docking block 357, causing the door panel 356 to open upward along the slide bar 355; at this time, the second motor 348 drives the rotating shaft 342 and the drive gear 3412 to rotate, meshing with the rack 346 to drive the translation plate 347 to drive the clamped controller to move horizontally along the limit groove, passing through the exit at the top of the test host 1 and entering the test chamber 353; after clamping is completed, the lifting component 33 descends and resets, the push rod 352 disengages from the docking block 357, the door panel 356 closes under its own weight, the sealing strip 358 ensures sealing, and the test host 1 then starts the aging test program.

[0055] In summary, by modularly cooperating with the feeding component 3, the suspension bracket 2, and the conveyor belt 4, an automated transfer channel is constructed between the conveyor belt 4 and the test host 1. The crossbeam 31, vertical frame 32, lifting component 33, and translation component 34 are sequentially connected to form a stable spatial displacement mechanism. With the help of the electric push rod 349 and the pneumatic suction cup 3411, the controller can achieve adaptive clamping. The entire transfer process can achieve continuous operation without manual intervention.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
