[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figures 1 to 6As shown, an automatic test device for automobile controllers includes: a frame 2 and a mounting platform 3, two test lines 4 for testing automobile controllers are arranged in parallel on the frame 2, the mounting platform 3 is fixed on the frame 2, and the two test lines 4 are separated by a metal partition plate 5; the test line 4 includes a conveying device 41, a test station and a water blowing station, a plurality of test trays 6 are arranged on the conveying device 41, and the test trays 6 are used to place and position the automobile controller; a test device 42 used in conjunction with the test trays 6 and for testing the automobile controller is arranged on the test station; a water blowing device 43 used in conjunction with the test trays 6 and for testing the automobile controller is arranged on the water blowing station.

[0028] In the present application, the core of the vehicle controller automatic test device is to support the entire test system through a frame 2 and a mounting platform 3, which includes two parallel test lines 4. The two lines are independent of each other through a metal partition plate 5, so that two test tasks can be processed at the same time to improve the test efficiency. Each test line 4 is composed of a conveying device 41, a test station and a water blowing station.

[0029] A plurality of test trays 6 are mounted on the conveying device 41 for placing and positioning the automobile controller. Through the automated conveying system, the controller can be smoothly moved from one station to another. At the inspection station, the inspection device 42 used in conjunction with the test tray 6 will perform necessary inspections on the automobile controller placed on the tray. These inspections may include circuit function tests, signal response tests, etc. After the inspection is completed, the automobile controller will be moved to the water blowing station. The water blowing device 43 here is also used in conjunction with the test tray 6 to remove dust or moisture that may exist on the surface of the controller, ensure the cleanliness and dryness of the equipment, and prevent performance problems caused by contamination.

[0030] By setting up two detection lines 4 in parallel, the device can process the tests of two controllers at the same time, which greatly improves the production efficiency compared to single-line operation. Through reasonable design, such as the use of metal partitions 5, vertical and horizontal spaces are effectively utilized, so that the equipment can achieve high-efficiency operation in a relatively small space. The automated conveying device 41 and testing process reduce manual operations, reduce error rates and operating costs, and improve production continuity and stability.

[0031] Specifically, a plurality of support columns 61 are fixed on the test tray 6 , and a positioning pin 611 is provided at the end of the support column 61 . The positioning pin 611 is used for mounting the automobile controller and positioning and fixing the automobile controller. A plurality of positioning holes 62 are opened on the test tray 6 .

[0032] The design of the positioning pin 611 allows the vehicle controller to be accurately mounted and positioned, ensuring the position stability of the controller during the test process. This precise positioning is critical to the reliability and repeatability of the test results.

[0033] Specifically, the detection device 42 includes an upper detection plate 421 and a first lifting and positioning mechanism 422. A plurality of first mounting columns 31 are fixed on the mounting platform 3. The upper detection plate 421 is detachably mounted on the top of the first mounting column 31. A plurality of detection connectors 4211 are mounted on the upper detection plate 421. A first pressure pin 4212 corresponding to the positioning pin 611 is fixed on the upper detection plate 421. The first pressure pin 4212 can be abutted against the upper end of the positioning pin 611 to limit the automobile controller from falling off the positioning pin 611. The first lifting and positioning mechanism 422 is mounted on the mounting platform 3, and the first lifting and positioning mechanism 422 is used to move the test tray 6 upward.

[0034] The upper detection plate 421 is detachably mounted on the top of the first mounting column 31. This design allows the upper detection plate 421 to be easily replaced or maintained as needed to adapt to different test requirements or perform equipment maintenance. A number of detection connectors 4211 are installed on the upper detection plate 421, which are used to connect to the corresponding test points on the controller for functional testing. The first pressure pin 4212 is designed to align with and abut against the upper end of the positioning pin 611, so that the car controller can be restricted from falling off or moving from the positioning pin 611 during the test, ensuring the accuracy and safety of the test. The main function of the first lifting and positioning mechanism 422 is to move the test tray 6 upward so that the car controller on the test tray 6 is properly docked with the detection connector 4211 and the first pressure pin 4212 on the upper detection plate 421. By precisely controlling the position of the test tray 6, the consistency and accuracy of each test can be ensured.

[0035] Specifically, a first fan 32 is fixed on the mounting platform 3 , and a second fan 4213 is fixed on the upper detection plate 421 .

[0036] The configuration of the first fan 32 and the second fan 4213 allows cooling air to be more evenly and efficiently distributed throughout the device, particularly in the detection and electronic component areas where heat may be concentrated during the detection process of the detection device 42. This helps prevent overheating, ensures that the electronic equipment operates at an optimal temperature, and prolongs the life of the equipment. When testing electronic components, temperature fluctuations may affect the accuracy of the test results. By using two fans, the temperature of the test environment can be more effectively controlled, thereby improving the reliability and consistency of the test data.

[0037] Specifically, the first lifting and positioning mechanism 422 includes a first fixed frame 4221, a first cylinder 4222, and a first lifting plate 4223. The first fixed frame 4221 is fixed under the mounting table 3, the first cylinder 4222 is fixed on the first fixed frame 4221, the first lifting plate 4223 is fixed on the end of the piston rod of the first cylinder 4222, and a plurality of first positioning columns 42231 are fixed on the first lifting plate 4223. The first positioning columns 42231 can be inserted into the positioning holes 62 to limit the movement of the test tray 6.

[0038] In the present application, the first cylinder 4222 is fixed on the first fixed frame 4221, and the rising and falling of the first lifting plate 4223 is realized by controlling the piston movement of the cylinder. The first lifting plate 4223 is fixed to the end of the piston rod of the first cylinder 4222, and a plurality of first positioning columns 42231 are fixed on it. When the cylinder is operated to raise the lifting plate, these positioning columns will be inserted into the positioning holes 62 on the test tray 6 to limit the movement of the test tray 6 and ensure the stability and precise position of the test tray 6 during the test process.

[0039] By using the first positioning column 42231 in conjunction with the positioning hole 62 , the test tray 6 can be restricted and positioned with high precision to prevent movement during the test, thereby ensuring the accuracy and repeatability of the test.

[0040] Specifically, the water blowing device 43 includes a pressure plate 431 and a second lifting and positioning mechanism 432. A plurality of second mounting columns 33 are fixed on the mounting platform 3. The pressure plate 431 is detachably mounted on the top of the second mounting column 33. A plurality of second pressing pins 4311 are fixed on the pressure plate 431. The second pressing pins 4311 can abut against the upper end of the positioning pin 611 to limit the automobile controller from falling off the positioning pin 611. The second lifting and positioning mechanism 432 is installed on the mounting platform 3, and the second lifting and positioning mechanism 432 is used to move the test tray 6 upward.

[0041] The pressing plate 431 is detachably mounted on the top of the second mounting column 33, which is convenient for maintenance or replacement. A plurality of second pressing pins 4311 are fixed on the pressing plate 431. The second pressing pins 4311 are designed to abut against the upper end of the positioning pin 611. When the test tray 6 moves up to the bottom of the pressing plate 431, the second pressing pins 4311 can effectively limit the car controller from coming off the positioning pin 611, ensuring the stability of the controller during the water blowing process. The second lifting and positioning mechanism 432 is similar to the first lifting and positioning mechanism 422, and is installed on the mounting platform 3, and is used to control the upward movement of the test tray 6, so that the controller of the test tray 6 is aligned with the second pressing pins 4311 on the pressing plate 431 to stabilize the position of the controller.

[0042] By precisely controlling the position of the test tray 6 and stabilizing the controller, the controller can be positioned accurately during the water blowing process, thereby improving the cleaning efficiency and effect. The design of the second pressure needle 4311 can effectively prevent the controller from shifting or falling off during the high-pressure water blowing operation, protecting the controller from damage.

[0043] Specifically, the second lifting and positioning machine 432 includes a second fixed frame 4321, a second cylinder 4322, and a second lifting plate 4323. The second fixed frame 4321 is fixed below the mounting platform 3, the second cylinder 4322 is fixed on the second fixed frame 4321, the second lifting plate 4323 is fixed to the end of the piston rod of the second cylinder 4322, and a plurality of second positioning columns 43231 are fixed on the second lifting plate 4323. The second positioning columns 43231 can be inserted into the positioning holes 62 to limit the movement of the test tray 6; at least one first air blowing pipe 43232 is fixed on the second lifting plate 4323; and at least one second air blowing pipe 4312 is fixed on the pressing plate 431.

[0044] The second cylinder 4322 is fixed on the second fixing frame 4321 and is responsible for controlling the lifting and lowering of the second lifting plate 4323. The second lifting plate 4323 is fixed on the piston rod end of the second cylinder 4322 and is provided with a plurality of second positioning columns 43231, which are used to be inserted into the positioning holes 62 on the test tray 6, so as to stabilize the test tray 6 and prevent it from moving during the water blowing process. The first air blowing pipe 43232 is fixed on the second lifting plate 4323 and is used to blow compressed air to the controller to remove dust and moisture on the surface of the controller. The second air blowing pipe 4312 is fixed on the pressing plate 431 and cooperates with the first air blowing pipe 43232 to blow air to the controller from two directions to ensure the comprehensive cleaning of the controller. The first air blowing pipe 43232 and the second air blowing pipe 4312 correspond to the front and back sides of the automobile controller respectively.

[0045] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative position relationship and movement status of the components in a certain specific posture, as shown in the accompanying drawings.
