Description

Technical Field

[0001] This invention relates to the field of automatic testing equipment technology, and in particular to an automatic ECU feeding and testing device. Background Technology

[0002] ECU (electronic control unit, i.e. computer control module) is the core component of automotive electronic control system, and its core functions are real-time monitoring, decision-making and control.

[0003] In today's era of rapid advancements in automotive technology, as vehicles become increasingly intelligent, their functions are becoming more diverse and sophisticated. Against this backdrop, more and more car seats are being equipped with automatic massage devices. These devices cleverly simulate the pressing, kneading, and pounding motions of human hands, effectively relieving fatigue in the lower back and other areas of the driver and passengers during driving, thus enhancing driving comfort and experience.

[0004] The Electronic Control Unit (ECU), a key control component in automobiles, plays a crucial role in the operation of automatic massage devices. It is the core device controlling the pneumatic mounting system and is responsible for the precise regulation of the entire massage system. During operation, the ECU receives rich data from various sensors located in key areas of the seat, which can perceive the seat's status and the occupants' posture in real time. Upon receiving this data, the ECU quickly performs complex calculations and logical decisions, based on pre-set control strategies and algorithms, and after precise analysis and judgment, outputs corresponding control signals. These signals are precisely transmitted to the actuators, i.e., the specific massage actuators, driving them to perform corresponding actions to achieve the massage operation for the occupants, thereby relieving fatigue.

[0005] However, traditional testing methods mainly involve manually testing each function one by one. This manual testing method is not only time-consuming and labor-intensive, but also inefficient. Due to the intervention of human factors, the accuracy of the test results is difficult to guarantee, and errors and instability are prone to occur. It is impossible to comprehensively and accurately evaluate the performance and reliability of the ECU, and it is difficult to meet the requirements of the modern automotive industry for strict control over product quality and performance.

[0006] Therefore, those skilled in the art are dedicated to developing an automated ECU loading and testing device that facilitates the automatic and rapid testing of various ECU functions, thereby improving the testing efficiency and accuracy of ECUs. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide an automatic ECU loading and testing device, which facilitates automatic and rapid testing of various functions of ECUs and improves the testing efficiency and accuracy of ECUs.

[0024] The beneficial effects of adopting the above-mentioned further solution are: the first lifting cylinder and the second lifting cylinder are located on both sides of the feeding and conveying assembly, respectively. Through the lifting action of the lifting cylinder and the horizontal pushing action of the horizontal cylinder, the material can be accurately entered into the positioning cavity, ensuring that the material is in the correct position during the test, which is conducive to the subsequent clamping and moving assembly accurately clamping and moving to the designated position.

[0025] Furthermore, the clamping and moving assembly includes a first clamping member and a second clamping member, which are respectively installed on both sides of the double-headed cylinder.

[0027] Furthermore, the lifting assembly includes a vertical mounting plate and a vertical moving plate. The vertical moving plate and the horizontal mounting plate are vertically connected.

The vertical power assembly rotates to drive the vertical moving plate to move up and down. The vertical mounting plate is installed on the horizontal moving assembly.

[0028] The beneficial effects of adopting the above-mentioned further solution are: the rotation of the vertical power component drives the vertical lead screw to rotate, and through the cooperation of the lead screw and the lead screw bearing, the vertical moving plate can move up and down smoothly, thereby realizing the adjustment of the material in the height direction, ensuring that the material can accurately reach the height position required for testing, which is conducive to subsequent movement and avoids collisions.

The longitudinal lead screw bearing is connected to the longitudinal moving plate. The rotation of the longitudinal power component drives the longitudinal moving plate to move longitudinally.

[0032] The beneficial effect of adopting the above-mentioned further solution is that the longitudinal power component drives the longitudinal lead screw to rotate, and through the cooperation of the lead screw and the lead screw bearing, the longitudinal moving plate can move smoothly in the longitudinal direction, thereby enabling the clamped material to be precisely positioned in the longitudinal direction.

[0033] Furthermore, the testing component includes a testing platform, with a clamping cylinder installed at the upper end of the testing platform, and multiple testers for testing materials installed on the side wall of the testing platform.

[0034] The beneficial effects of adopting the above-mentioned further solution are: the clamping cylinder can press the material firmly onto the test bench, preventing displacement or shaking during the test, thus ensuring the accuracy of the test.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0051] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, an automatic ECU feeding and testing device includes...

[0052] Feeding and conveying assembly 1 is mounted on frame 2 for conveying materials;

[0053] The barcode scanning component 3 is installed on the feeding conveyor component 1;

[0054] Positioning component 4 is installed on the feeding conveyor component 1;

[0055] Clamping and moving assembly 5, which is mounted on the frame 2, is used to clamp and move materials onto the test assembly 6;

[0056] The discharge conveyor assembly 7 is installed on the frame 2 and is used to convey the tested and qualified materials to the designated location.

[0057] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the feeding conveying assembly 1 includes a feeding conveying bracket 8, with feeding conveying rollers 9 installed at both ends of the feeding conveying bracket 8. A feeding conveying belt 10 is fitted over the two feeding conveying rollers 9. The feeding conveying rollers 9 are also connected to a feeding power assembly 11, which is usually a motor. The motor drives the feeding conveying rollers 9 to rotate, thereby driving the feeding conveying belt 10 to circulate, so that the ECU material placed on the feeding conveying belt 10 can be smoothly conveyed forward along a preset path.

[0058] like Figure 1 , Figure 2 and Figure 3 As shown, in another embodiment, the barcode scanning component 3 includes a limiting cylinder 12 and a barcode scanner 14. The limiting cylinder 12 is mounted on a limiting frame 13, which is mounted on the frame 2. The output end of the limiting cylinder 12 is located on the upper side of the feeding conveyor component 1, so that when the limiting cylinder 12 extends, it blocks and limits the material in the ECU. The barcode scanner 14 is mounted on the limiting frame 13 for scanning the material code. The limiting frame 13 is also equipped with a photoelectric sensor for detecting the material position. Specifically, when the material moves with the feeding conveyor belt 10 to below the output end of the limiting cylinder 12, the limiting cylinder 12 receives a signal and actuates, extending its output end downward to limit the material, causing the material to temporarily stop moving forward and maintain a stable position. At this time, the barcode scanner 14 starts, scans the code on the material, and quickly and accurately reads the material's model, batch, and other identification information.

[0059] In one embodiment, the positioning component 4 includes a first positioning element 15 and a second positioning element 16. Positioning cavities that mate with the material are provided on the opposing surfaces of the first positioning element 15 and the second positioning element 16. The shape and size of the positioning cavities are adapted to the shape of the material in the ECU, ensuring that the material is in a precise predetermined position after entering the positioning cavity. A first lifting cylinder 17 is mounted on the lower side of the first positioning element 15. The first lifting cylinder 17 is mounted on the side wall of the feeding and conveying component 1 via a first positioning frame 18. A horizontal cylinder 19 is mounted on the side wall of the second positioning element 16. The horizontal cylinder 19 is mounted on the second positioning frame. A second lifting cylinder 20 is mounted on the lower side of the second positioning element 16. The first lifting cylinder 17 and the second lifting cylinder 20 are located on opposite sides of the feeding and conveying component 1. When the material after scanning continues to be conveyed forward to the positioning station, the first lifting cylinder 17 and the second lifting cylinder 20 move downwards simultaneously, limiting the first positioning element 15 and the second positioning element 16 from both sides of the feeding conveying assembly 1. At the same time, the horizontal cylinder 19 pushes the second positioning element 16 towards the first positioning element 15. The two work together to accurately push the material into the positioning cavity, completing precise positioning and facilitating the subsequent precise clamping of the clamping and moving assembly 5. In a specific embodiment, a dual-station clamping is adopted. When the first lifting cylinder 17 and the second lifting cylinder 20 move upwards, the material can smoothly pass to the next station.

[0060] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, the clamping and moving assembly 5 includes a first clamping member 21 and a second clamping member 22. The first clamping member 21 and the second clamping member 22 are respectively mounted on both sides of the double-headed cylinder 23. The double-headed cylinder 23 is mounted on the lifting assembly via a horizontal mounting plate 24. The lifting assembly is mounted on the transverse moving assembly, and the transverse moving assembly is mounted on the longitudinal moving assembly. After the material is positioned, the longitudinal moving assembly, the transverse moving assembly, and the lifting and moving assembly work together to move the horizontal mounting plate 24 to a designated position. The double-headed cylinder 23 is activated upon receiving a signal, and its piston rods on both sides drive the first clamping member 21 and the second clamping member 22 to move towards each other, thereby tightly clamping the material located between them. Afterward, the lifting assembly, the transverse moving assembly, and the longitudinal moving assembly operate again, and according to the preset program and test requirements, accurately move the clamped material to the designated position of the test assembly 6, realizing the three-dimensional spatial position adjustment of the material and ensuring that the material can be accurately aligned with the various test interfaces of the test equipment.

[0061] In a specific embodiment, the lifting assembly includes a vertical mounting plate 25 and a vertical moving plate 26. The vertical moving plate 26 and the horizontal mounting plate 24 are vertically connected. A vertical power assembly 27 is installed at the end of the vertical mounting plate 25. A vertical lead screw is connected to the output end of the vertical power assembly 27. A vertical lead screw bearing is sleeved on the vertical lead screw. The vertical lead screw bearing is connected to the vertical moving plate 26. The rotation of the vertical power assembly 27 drives the vertical lead screw to rotate. By means of the transmission principle of the lead screw and the lead screw bearing, the rotational motion is converted into the vertical linear motion of the vertical moving plate 26, thereby driving the horizontal mounting plate 24 and the clamping moving assembly 5 installed on it to adjust their height in the vertical direction, so that the material can accurately reach the specific height position required for testing. The vertical mounting plate 25 is installed on the horizontal moving assembly.

[0062] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, the lateral movement assembly includes a lateral movement plate and a lateral mounting plate 28. The lateral movement plate is connected to the vertical mounting plate 25. A lateral power assembly 29 is installed at the end of the lateral mounting plate 28. A lateral lead screw is connected to the output end of the lateral power assembly 29. A lateral lead screw bearing is sleeved on the lateral lead screw. The lateral lead screw bearing is connected to the lateral movement plate. The rotation of the lateral power assembly 29 drives the lateral lead screw to rotate. Based on the transmission cooperation between the lead screw and the lead screw bearing, the lateral movement plate, together with the vertical mounting plate 25 on it and the entire clamping and moving system, are driven to move smoothly in the lateral direction, realizing the precise adjustment of the material in the horizontal lateral position. The lateral movement plate is installed on the longitudinal movement assembly, which provides the basic support and power transmission path for its longitudinal position movement.

[0063] In this embodiment, the longitudinal moving component includes a longitudinal moving plate 30 and a longitudinal mounting plate 31. The longitudinal moving plate 30 is connected to the transverse mounting plate 28. A longitudinal power component 32 is installed at the end of the longitudinal mounting plate 31. A longitudinal lead screw is connected to the output end of the longitudinal power component 32. A longitudinal lead screw bearing is sleeved on the longitudinal lead screw. The longitudinal lead screw bearing is connected to the longitudinal moving plate 30. The rotation of the longitudinal power component 32 drives the longitudinal lead screw to rotate, thereby driving the longitudinal moving plate 30, together with the transverse mounting plate 28 on it and the entire front-end clamping moving system, to move a long distance in the longitudinal direction. The longitudinal moving component is generally installed on the bottom guide rail of the frame 2 and moves along the extension direction of the guide rail. It is used to move the material from the feeding end conveying station to each test station and the final discharge station in sequence, so as to realize the large-range position control of the entire equipment on the material transmission path and ensure that the material can pass through each working point in a predetermined order.

[0064] like Figure 1 , Figure 2 and Figure 5As shown, in this embodiment, the test assembly 6 includes a test platform 33. A clamping cylinder 34 is installed on the upper end of the test platform 33, and multiple testers 35 for testing materials are installed on the side wall of the test platform 33. When the clamping and moving assembly 5 transports the material to the top of the test platform 33 and aligns it precisely, the clamping cylinder 34 actuates, and its piston rod extends downward to firmly press the material onto the surface of the test platform 33, preventing any form of displacement or shaking of the material during the test and ensuring the stability of the test process. Multiple testers 35 of different types and functions are installed around the material on the side wall of the test platform 33. These testers 35 can simultaneously perform comprehensive testing on multiple key indicators such as the electrical performance, signal transmission, and logic function of the ECU material. Each tester 35 is connected to the control host through wires and transmits test data to the host for analysis and processing in real time. Once any abnormal parameter is detected, the system can immediately determine that the material is unqualified and move it to the defective product box by clamping and moving assembly 5, while qualified materials are moved to the discharge conveyor assembly 7 by clamping and moving assembly 5.

[0065] like Figure 1 , Figure 2 and Figure 6 As shown, in some embodiments, the discharge conveying assembly 7 includes a discharge conveying bracket 36, with discharge conveying rollers 37 mounted at both ends of the discharge conveying bracket 36. A discharge conveying belt 38 is fitted over the discharge conveying rollers 37, and the discharge conveying rollers 37 are also connected to a discharge power assembly 39. After the material completes testing, the clamping and moving assembly 5 releases the material from the testing platform 33 and clamps and moves it onto the discharge conveying belt 38, driving the discharge conveying rollers 37 to rotate and causing the discharge conveying belt 38 to circulate, smoothly conveying the qualified material to the downstream packaging or storage area, ensuring the continuity and efficiency of the entire production testing process.

[0066] like Figure 7 and Figure 8 As shown in other embodiments, since the scanning end of the barcode scanner 14 is exposed to the air for a long time, after a period of use, dust will cover the scanning end of the barcode scanner 14 under the action of electrostatic force, causing the lens to become blurry and unable to scan quickly. At this time, the operator needs to manually clean the dust on the lens surface, which reduces the detection efficiency of the testing equipment.

[0067] In this embodiment, a sliding plate 40 is provided on the lower side of the limiting frame 13. The two ends of the sliding plate 40 are installed on the lower side of the limiting frame 13 through sliding brackets. The sliding plate 40 is provided with a through hole 41 that cooperates with the scanning end of the barcode scanner 14. One end of the sliding plate 40 is connected to a fixing plate 49 through a compression spring 42. The other end of the sliding plate 40 is connected to a wedge block 43 through a connecting bracket. A limiting baffle 44 is installed at the output end of the limiting cylinder 12. An abutment wheel 45 for cooperating with the inclined surface of the wedge block 43 is installed on the limiting baffle 44.

[0068] like Figure 8 As shown, when the limiting cylinder 12 retracts, the upper end of the wedge block 43 abuts against the abutting wheel 45, and the sliding plate 40 moves towards the limiting cylinder 12 under the action of the compression spring 42, so that the through hole 41 is misaligned with the scanning end of the barcode scanner 14, and the sliding plate 40 blocks the scanning end of the barcode scanner 14, reducing dust adhesion to the scanning end of the barcode scanner 14.

[0069] like Figure 7 As shown, when the limiting cylinder 12 extends, the limiting baffle 44 blocks the material, the lower end of the wedge block 43 abuts against the abutting wheel 45, the sliding plate 40 compresses the compression spring 42 and moves away from the limiting cylinder 12, so that the through hole 41 is directly opposite the scanning end of the barcode scanner 14. At this time, the material is blocked by the limiting baffle 44, and the scanning end of the barcode scanner 14 can scan the information on the material.

[0070] Furthermore, the lower end of the limiting frame 13 is connected to an air cylinder 46. A piston inside the air cylinder 46 is connected to a wedge block 43 via a connecting rod 47. A hose 48 is connected to the air outlet of the air cylinder 46, and the other end of the hose 48 is installed on the side wall of the through hole 41 and faces the scanning end of the barcode scanner 14. When the limiting cylinder 12 extends and retracts, pushing the wedge block 43 and the sliding plate 40 to move away from the limiting cylinder 12, the wedge block 43 drives the connecting rod 47 and the piston to compress the gas inside the air cylinder 46. The compressed gas is discharged from the hose 48 and blown towards the scanning end of the barcode scanner 14, thereby reducing the adhesion of ash to the scanning end of the barcode scanner 14. A valve can also be installed inside the hose 48. The valve opens only when the compressed gas reaches a certain pressure value, allowing the compressed gas to purge the scanning end of the barcode scanner 14.
