Description

Technical Field

[0001] This invention relates to the field of automotive window regulator assembly testing technology, specifically to an automotive window regulator assembly oiling load testing device. Background Technology

[0002] In the final inspection of automotive window regulators, comprehensive performance tests are required on various models and door configurations of the regulator assemblies, including stall force, operating current, speed, and stroke.

[0003] Current testing equipment generally suffers from rigid design and insufficient flexibility, mainly in the following aspects:

[0004] 1. Disjointed quality inspection and process flow: Defect detection, necessary processes (such as guide rail lubrication) and performance testing are often completed at different workstations by different equipment. The process is discrete, which increases work-in-process inventory, space occupation and quality control difficulty, and data is difficult to trace.

[0005] 2. To address the issue of lubrication status changes caused by process flow, an industry solution has emerged that integrates the oiling mechanism directly into the noise testing booth, completing the oiling and noise testing processes sequentially within the same booth. While this solution avoids product flow issues, it still suffers from insurmountable core drawbacks: First, the noise testing booth is a high-precision acoustic testing environment with extremely high requirements for controlling vibration sources, noise sources, and airflow disturbances within the testing space. The grease pump, drive motor, transmission module, and pipeline valve assembly associated with the oiling mechanism are themselves continuous sources of vibration and noise. The vibration and noise generated during their operation directly interfere with the signal acquisition of the acoustic testing equipment, resulting in test data that cannot accurately reflect the noise performance of the window lift assembly itself, severely reducing testing accuracy and the ability to identify product noise defects. Second, noise testing equipment is expensive and difficult to maintain; adding extra equipment within the booth would be prohibitively costly. Third, the existing noise test internal load only provides a static load with a fixed counterweight, without reference data before oiling, and does not collect dynamic load curves throughout the entire stroke. It only meets the basic working condition requirements of noise testing, cannot identify subtle load defects that affect product lifespan, and cannot determine the quality of the oiling process. Summary of the Invention

[0006] The purpose of this invention is to solve the above problems by providing an oiling load testing device for automotive window regulator assemblies.

[0007] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0008] A test device for oiling load of automotive window regulator assembly includes a frame, a central quick interface in the middle of the frame, a test load at the top of the frame, the test load can apply load to the glass bracket in the automotive window regulator assembly, and an oiling mechanism above the test load can apply lubricating oil to the slide plate.

[0009] The frame is equipped with an ejection mechanism, on which a switching fixture is installed. The switching fixture is designed according to the model of the automotive window regulator assembly. The switching fixture can hold the automotive window regulator assembly and read the data of the automotive window regulator assembly. The switching fixture is equipped with a quick-connect tray, which can be quickly connected to the central quick interface.

[0010] Furthermore, a touch display is provided on the outside of the rack, and the operator selects the corresponding product model and gear from the touch display.

[0011] Furthermore, the test load includes a guide linear slide rail module fixedly installed on the frame, a guide slide is installed on the guide linear slide rail module, a load arm is slidably connected to the guide slide, a load hydraulic cylinder is fixedly installed on the guide slide, the telescopic end of the load hydraulic cylinder is connected to the load arm, and the load arm can press on the glass bracket when it descends.

[0012] Furthermore, two sets of limiting linear slide rail modules are provided below the guide linear slide rail module, and each set of limiting linear slide rail modules is equipped with a stop bracket.

[0013] Furthermore, the oiling mechanism includes an oiling horizontal linear slide rail module fixedly installed on the frame, the oiling horizontal linear slide rail module being located above the guide linear slide rail module, an oiling vertical drive module being installed on the oiling horizontal linear slide rail module, an oiling brush head being installed on the oiling vertical drive module, and the oiling brush head being able to be inserted into the slide plate.

[0014] Furthermore, a double-headed cylinder is installed on the outer side of the oiling brush head. An outer guide is fixedly installed on the bidirectional telescopic end of the double-headed cylinder. When the two outer guides are brought together, they can be clamped on the outer side of the slide plate.

[0015] Furthermore, the ejection mechanism includes a lifting cylinder and a discharge bin. The discharge bin is fixedly installed on the front of the frame, and the lifting cylinder is fixedly installed inside the frame. A lifting head is fixedly installed on the top of the telescopic end of the lifting cylinder, and a lifting port is provided on the top of the lifting head.

[0016] Furthermore, the switching fixture includes a fixture frame and a motor assembly fixture. The bottom of the fixture frame is equipped with a lifting connector that can be inserted into a lifting socket. The top of the fixture frame is equipped with a guide ramp that guides the automotive window regulator assembly to the material drop chamber. The motor assembly fixture is bolted to the frame. A cylinder is vertically mounted inside the motor assembly fixture. A clamping rod is mounted on the top of the telescopic end of cylinder one, clamping the motor assembly of the automotive window regulator assembly onto the motor assembly fixture. A cylinder is horizontally mounted at the bottom of the motor assembly fixture. A test sensor is mounted on the telescopic end of cylinder two, and the test sensor can be plugged into the sensor interface of the motor assembly. Two sets of foot molds are mounted on the top of the motor assembly fixture. A cylinder is mounted on the outside of the foot molds. A foot clamping plate is fixedly mounted on the telescopic end of cylinder three, clamping the foot of the automotive window regulator assembly onto the foot mold.

[0017] Furthermore, clamping cylinders are fixedly installed on both the left and right sides of the frame, and the two sets of clamping cylinders clamp the left and right ends of the slide plate.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. This invention applies a downward pressure load to the glass bracket through a test load. The motor assembly drives the glass bracket to slide along the slide plate from left to right. When the glass bracket reaches the middle, the oiling mechanism applies oil from the left end to the slide plate. When the glass bracket moves to the far right, the lubricant is applied to the middle of the slide plate. Then, the glass bracket slides along the slide plate from right to left. When the glass bracket reaches the middle, the oiling mechanism applies oil from the right end to the slide plate. When the glass bracket moves to the far left, the lubricant is applied to the middle of the slide plate. This allows the oiling to be performed within the test cycle window, and the testing and oiling are carried out simultaneously, resulting in high overall process efficiency.

[0020] 2. This invention combines the oiling process with the testing process, eliminating the need for an oiling mechanism in the subsequent noise testing shed. Separating oiling from noise testing reduces the impact of mechanism operation on noise testing, resulting in lower costs. Simultaneously, it enables the acquisition of dynamic load curves throughout the entire stroke, including baseline testing before oiling and retesting after oiling. This accurately identifies jamming points, load peaks, and fluctuation amplitudes throughout the entire stroke, directly quantifying the oiling lubrication effect through the difference between the pre- and post-oiling data. The accuracy can cover process-level control requirements. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0032] Example 1, as Figures 1-9 As shown, an oiling load testing device for an automotive window regulator assembly includes a frame 1, a central quick interface 3 in the middle of the frame 1, a test load 4 on the top of the frame 1, the test load 4 can apply a load to the glass bracket 84 in the automotive window regulator assembly 8, and an oiling mechanism 5 is provided above the test load 4, the oiling mechanism 5 can apply lubricating oil to the slide plate 81.

[0033] The frame 1 is equipped with an ejection mechanism 6, and a switching fixture 7 is installed on the ejection mechanism 6. The switching fixture 7 is designed according to the model of the automotive window regulator assembly 8. The switching fixture 7 can hold the automotive window regulator assembly 8 and can read the data of the automotive window regulator assembly 8. The switching fixture 7 is equipped with a quick-connect tray 74, which can be quickly connected to the central quick interface 3.

[0034] A touch screen 2 is provided on the outside of the rack 1, and the operator selects the corresponding product model and gear from the touch screen 2.

[0035] Clamping cylinders 9 are fixedly installed on both the left and right sides of the frame 1. The two sets of clamping cylinders 9 clamp the left and right ends of the slide plate 81.

[0036] Step 1: (1) The production plan is issued with testing tasks that include the product model (e.g., “Model A - Right Front Door”).

[0037] (2) The operator takes out the corresponding special tooling module from the tooling storage rack and moves it to the host.

[0038] (3) Install the corresponding switching fixture 7 on the frame 1. Figure 6 For the right front door tooling, Figure 7 (For the left rear door tooling), the quick-connect plate 74 is quickly connected to the central quick interface 3, and the operator selects the corresponding product model gear from the touch display 2.

[0039] Step 2: (1) Workpiece loading and interlock detection: The operator puts the car window lifter assembly 8 into the workpiece and switches the dedicated detection mechanism integrated in the tooling 7. If it passes the test, the test will begin.

[0040] (2) Adaptive performance test: The host executes the test program for this model to measure its unique parameters.

[0041] (3) Parallel lubrication: During the test cycle window, the lubrication mechanism 5 performs precise lubrication for the arc of the slide plate 81 of this model.

[0042] Specific testing steps: The automotive window regulator assembly 8 uses a motor assembly 82 to first drive the glass bracket 84 to slide along the slide plate 81 from right to left. Then, a test load 4 is applied to the glass bracket 84, providing a downward load. The motor assembly 82 drives the glass bracket 84 to slide along the slide plate 81 from left to right. When it reaches the middle, the oiling mechanism 5 applies oil from the left end to the slide plate 81. When the glass bracket 84 moves to the far right, the lubricant is applied to the middle of the slide plate 81. Then, the glass bracket 84 slides along the slide plate 81 from right to left. When it reaches the middle, the oiling mechanism 5 applies oil from the right end to the slide plate 81. When the glass bracket 84 moves to the far left, the lubricant is applied to the middle of the slide plate 81, achieving oiling within the test cycle window. This allows for the acquisition of dynamic load curves throughout the entire stroke, including baseline testing before oiling and retesting after oiling. It accurately identifies jamming points, load peaks, and fluctuation amplitudes throughout the entire stroke, directly quantifying the oiling lubrication effect through the difference between the pre- and post-oiling data. The accuracy can cover process-level control requirements.

[0043] Step 3: (1) After the test and oiling are completed, the ejection mechanism 6 will automatically eject the product and let it slide down.

[0044] If the next testing task involves a different model, the operator only needs to change the switching fixture 7. The corresponding product model is selected on the touch display 2, and all test parameters and processes are automatically switched without any manual adjustment or calibration.

[0045] Includes the following system: Standardized host platform (the fixed part on rack 1).

[0046] Universal power and measurement base: integrates a universal motor drive power supply, a high-precision fixed force sensor, a current / voltage acquisition module, a data acquisition host computer, and a main control PLC (all mounted on rack 1, with no specific location restrictions). All measurement sensors and execution cores are fixed to the main unit and are not affected by the product model.

[0047] Central Quick Interface 3: This is a high-performance industrial quick-change panel, serving as the sole standardized interface for mechanical, electrical, pneumatic, and signal connections between the main unit and all variable tooling modules.

[0048] A series of interchangeable tooling modules (variable parts, covering the product family).

[0049] Core design concept: Design and manufacture independent dedicated tooling modules (switching tooling 7) for each different vehicle type or model of single-rail rope wheel lift. All tooling follows the same interface standard, but carries different product adaptation functions.

[0050] Intelligent control system and process database (this refers to the equipment software program, which is only briefly described and not specifically limited).

[0051] Tooling identification and management: The currently installed tooling model can be called through a visual touch screen, and the corresponding test program, parameters and oiling trajectory can be automatically called.

[0052] Flexible process control: The PLC dynamically coordinates the timing and logic of testing, parallel oiling, and product ejection based on the product model.

[0053] Centralized process database: Stores test levels, acceptable ranges, and oiling paths for all programmed product models, supporting rapid import of data for new vehicle models, achieving ultimate flexibility of "changing tools and changing products." The host computer can archive all test data for easy traceability.

[0054] Example 2, as Figures 2-3 As shown, a test load 4 structure is provided;

[0055] The test load 4 includes a guide linear slide rail module 41 fixedly installed on the frame 1. A guide slide 42 is installed on the guide linear slide rail module 41. A load arm 43 is slidably connected to the guide slide 42. A load hydraulic cylinder 44 is fixedly installed on the guide slide 42. The telescopic end of the load hydraulic cylinder 44 is connected to the load arm 43. When the load arm 43 descends, it can press on the glass bracket 84.

[0056] Below the guide linear slide rail module 41 are two sets of limiting linear slide rail modules 45, and each set of limiting linear slide rail modules 45 is equipped with a stop bracket 46.

[0057] By controlling the operation of the load hydraulic cylinder 44, the load hydraulic cylinder 44 drives the load arm 43 to descend and press against the glass bracket 84, applying downward pressure to the glass bracket 84 and providing a load perpendicular to the slide plate 81. The guide linear slide rail module 41 provides guidance for the load arm 43. By adjusting the position of the stop bracket 46, the extreme positions of the left and right sliding of the guide slide 42 are limited, and the initial position of the glass bracket 84 when loaded can be accurately found, improving the positioning accuracy.

[0058] Example 3, as Figure 4 As shown, an oiling mechanism 5 structure is provided;

[0059] The oiling mechanism 5 includes an oiling horizontal linear slide rail module 51 fixedly installed on the frame 1. The oiling horizontal linear slide rail module 51 is located above the guide linear slide rail module 41. An oiling vertical drive module 52 is installed on the oiling horizontal linear slide rail module 51. An oiling brush head 53 is installed on the oiling vertical drive module 52. The oiling brush head 53 can be inserted into the slide plate 81.

[0060] A double-headed cylinder 54 is installed on the outside of the oiling brush head 53. An outer guide 55 is fixedly installed on the bidirectional telescopic end of the double-headed cylinder 54. When the two outer guides 55 are closed together, they can be clamped on the outside of the slide plate 81.

[0061] During oiling, the vertical drive module 52 is controlled to operate so that the oiling brush head 53 is inserted into the slide plate 81. Then, the double-headed cylinder 54 operates so that the two outer guide members 55 come together and clamp on the outside of the slide plate 81, allowing it to slide along the outside of the slide plate 81. This not only improves the stability of oiling, but also detects the width of the slide plate 81 by clamping. By adjusting the insertion depth of the oiling brush head 53, the bristles expand outward when squeezed, so that the bristles can completely cover the slide plate 81. Then, the horizontal linear slide rail module 51 drives the oiling brush head 53 to slide along the slide plate 81 to perform oiling.

[0062] The oiling mechanism 5 integrates a servo drive module, a quantitative valve oil supply system, and an adaptive brush head. Its motion program can be called according to the product model.

[0063] Example 4, as Figures 5-9 As shown, a structure of ejection mechanism 6 and switching fixture 7 is provided;

[0064] The ejection mechanism 6 includes a lifting cylinder 62 and a discharge bin 61. The discharge bin 61 is fixedly installed on the front of the frame 1, and the lifting cylinder 62 is fixedly installed inside the frame 1. A lifting head 63 is fixedly installed on the top of the telescopic end of the lifting cylinder 62, and a lifting port 64 is opened on the top of the lifting head 63.

[0065] The switching fixture 7 includes a fixture frame 71 and a motor assembly fixture 75. The bottom of the fixture frame 71 is equipped with a lifting connector 72, which can be inserted into a lifting socket 64. The top of the fixture frame 71 is equipped with a guide ramp 73, which guides the automotive window regulator assembly 8 to the unloading bin 61. The motor assembly fixture 75 is bolted to the frame 1. A cylinder 76 is vertically mounted inside the motor assembly fixture 75. A clamping rod 77 is mounted on the top of the telescopic end of the cylinder 76, which controls the electric motor of the automotive window regulator assembly 8. The motor assembly 82 is clamped on the motor assembly fixture 75. A second cylinder 78 is horizontally mounted on the bottom of the motor assembly fixture 75. A test sensor 79 is mounted on the telescopic end of the second cylinder 78. The test sensor 79 can be plugged into the sensor interface of the motor assembly 82. Two sets of foot molds 710 are provided on the top of the motor assembly fixture 75. A third cylinder 711 is provided on the outside of the foot mold 710. A foot clamping plate 712 is fixedly installed on the telescopic end of the third cylinder 711. The foot clamping plate 712 can clamp the foot 83 of the automotive window regulator assembly 8 on the foot mold 710.

[0066] The test sensor 79 can be integrated as needed, such as for screw missing detection (proximity sensor), electrical connectors, etc.

[0067] Assembly: Insert the corresponding lifting connector 72 into the lifting socket 64, and then fix the motor assembly fixture 75 onto the frame 1 with bolts.

[0068] Usage steps: Place the base 83 of the skateboard 81 into the base mold 710, and place the motor assembly 82 on the motor assembly fixture 75. Then, cylinder 1 76 runs, driving the clamping rod 77 to descend. The clamping rod 77 clamps the motor assembly 82 onto the motor assembly fixture 75. Cylinder 2 78 runs, driving the test sensor 79 to connect with the interface in the motor assembly 82. Cylinder 3 711 runs, driving the base clamping plate 712 to clamp the base 83 onto the base mold 710, thus completing the overall fixation of the car window regulator assembly 8.

[0069] After the test is completed, the automotive window regulator assembly 8 is released, and the lifting cylinder 62 drives the tooling frame 71 to rise through the lifting head 63. The tooling frame 71 drives the automotive window regulator assembly 8 to rise as a whole through the guide ramp 73. Under the action of gravity, the automotive window regulator assembly 8 slides down along the guide ramp 73 into the drop chamber 61.
