Technical Field

[0002] The front wheel steering motor is a key component in the steer-by-wire system, used to achieve precise control of the front wheel angle. Depending on the different layouts, the front wheel steering motor can be in the form of a single motor or a dual motor. The single motor front wheel steering has a simple structure and is easy to arrange, but does not have fault redundancy; the dual motor front wheel steering has higher redundancy and safety, but the cost is higher. In addition, the front wheel steering motor is usually used in conjunction with the steering actuator, receiving instructions from the main controller through the motor controller to complete the steering operation.

[0003] The steering motor needs to be assembled during processing. After assembly, the motor will undergo electrical testing and performance testing to ensure its reliability and safety in actual use. This includes testing the motor's power, speed, temperature rise and other parameters to ensure that they meet the design requirements. The power test verifies whether the motor meets the design requirements by measuring the output power of the motor under a specific load. The speed test checks whether the motor's speed is stable under no-load and load conditions and whether it is within the specified range. The temperature rise test measures the temperature rise of each component of the motor after the motor has been running continuously for a period of time to evaluate the motor's heat dissipation performance and heat resistance.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are 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.

[0030] Embodiment 1:

[0031] Combine the following Figure 1-Figure 10 The present invention describes an assembly test system for a front wheel steering motor.

[0032] like Figure 1-Figure 2 As shown, an embodiment of the present invention provides a front wheel steering motor assembly and testing system, which is used to assemble and test the steering motor. It includes:

[0033] The motor zeroing module 1 is used to zero the motor output shaft position on the steering motor. The main function of the motor zeroing module 1 is to accurately zero the motor output shaft position on the steering motor. Through calibration, it can ensure that the position of the motor output shaft is completely consistent with the preset zero point position, thereby improving the accuracy and stability of the steering system.

[0034] The motor zeroing module 1 includes an upper test head 10 and a lower test head 11. The upper test head 10 is used to connect the motor plug of the steering motor. The upper test head 10 is used to energize the steering motor to rotate the rotating motor. The lower test head 11 is used to connect the motor output shaft and zero the position of the motor output shaft. After the rotating motor rotates, the axial deviation from the center may occur, making the steering motor unstable. The lower test head 11 can make the shaft of the steering motor with axial deviation return to the zero point, thereby achieving the purpose of motor zeroing.

[0035] The first temperature test module 2, the first temperature refers to normal temperature, and is used to perform a first temperature power-on test on the steering motor after the motor is processed by the zero module 1 at normal temperature. The first temperature test module 2 can effectively evaluate the performance of the steering motor under normal working temperature through the first temperature power-on test.

[0036] like Figure 3-Figure 5 As shown, the second temperature module 3, the second temperature refers to a high temperature, which is used to increase the temperature of the steering motor. By heating the steering motor, the temperature requirement of the steering motor test in the next process is met.

[0037] The second temperature module 3 includes a curing furnace loading component 30, a unloading component 31, and a curing furnace 32. The curing furnace loading component 30 is used to place the steering motor into the curing furnace 32. The curing furnace 32 is used to heat the steering motor. The unloading component 31 is used to transport the heated steering motor to the line body 7. When the tray on the line body 7 reaches the preset position of the second temperature module 3, the tray lifting mechanism 9 will make the tray and the steering motor on the tray rise to the limit position. Then the barcode scanner reads the RFID on the steering motor to identify the information of the steering motor, including batch information. Then the curing furnace loading component 30 grabs the steering motor and puts the steering motor into the curing furnace fixture so that the steering motor is heated to the preset temperature in the curing furnace 32. The steering motor may appear in two states, OK and NG, during the heating process, that is, normal and abnormal at high temperature. Then the unloading component 31 grabs the steering motor that has reached the threshold and is OK and puts it into the tray. The NG steering motor is grabbed onto the carrier to repair or re-produce it.

[0038] The curing furnace loading assembly 30 includes a clamp 300, a lifting unit 301, a rotating cylinder 302, a clamp cylinder 303, a lifting cylinder 304 and a fixed bracket 305. The clamp cylinder 303 is used to drive the clamp 300 to clamp. The rotating cylinder 302 is used to drive the clamp cylinder 303 and the clamp 300 to rotate. The lifting cylinder 304 is fixedly connected to the fixed bracket 305 and is used to control the lifting unit 301 to lift. The clamp cylinder 303 pushes the clamp 300 through the pneumatic propulsion assembly so that the end of its claw can clamp the steering motor. Then, the lifting unit 301 drives the clamp cylinder 303 and the clamp 300 to rise under the action of the lifting cylinder 304, and puts the steering motor into the fixture in the curing furnace.

[0039] The second temperature test module 4 is used to perform high temperature test on the steering motor. It is mainly used to simulate the performance, stability and durability of the steering motor in an extremely high temperature environment. Through high temperature testing, potential problems can be discovered in time to improve the quality and reliability of the steering motor.

[0040] The second temperature test module 4 includes a temperature sensor 40 and a heating module 41. The temperature sensor 40 is used to detect the temperature of the steering motor. The temperature information of the steering motor is transmitted to the heating module 41. If the temperature of the steering motor drops below 80°C, the heating module 41 is used to compensate the temperature of the steering motor and output a high-temperature motor, so that the temperature of the steering motor can meet the test requirements.

[0041] like Figure 6-Figure 8 As shown, the cooling module 5 is used to cool down the steering motor after being tested by the second temperature test module 4. The cooling module 5 cools down the steering motor tested by the second temperature test module 4, so that the temperature of the steering motor drops to a normal temperature state, so as to better cope with the test of the next process.

[0042] The cooling module 5 includes at least one cooling unit 50. The cooling unit 50 includes a protective cover 500, a peep plate 501, a cover plate 502, a plurality of cooling fans 503, a butterfly hinge 504 and a bracket 505. The peep plate 501 is fixedly connected to the protective cover 500, and the protective cover 500 is fixedly connected to the bracket 505. The protective cover 500 closes the heat dissipation environment of the steering motor, and prevents the external environment from interfering with the heat dissipation environment, thereby improving the heat dissipation efficiency of the steering motor. The peep plate 501 provides a window for the operator to monitor the heat dissipation progress at any time, so that the operator can find problems in the heat dissipation process more promptly. The two ends of the butterfly hinge 504 are fixedly connected to the cover plate 502 and the protective cover 500, respectively, and a plurality of cooling fans 503 are fixedly connected to the cover plate 502. Using a plurality of cooling fans 503 to dissipate heat for the steering motor at the same time can improve the heat dissipation efficiency of the steering motor, reduce the duration of the cooling process, and thus improve the efficiency of the entire production process. The cover plate 502 can be opened at any time to deal with the steering motor with problems. Prevent the problem motor from flowing backwards and affecting the overall production quality.

[0043] The first temperature abnormal sound test module 6 is used to perform an abnormal sound test on the steering motor after cooling to determine whether it has abnormal sound or noise. By performing the abnormal sound test, it is possible to effectively detect whether the steering motor has an abnormal sound problem at normal temperature, thereby ensuring the quality and stability of the motor.

[0044] The first temperature abnormal sound test module 6 includes a noise testing mechanism 60 and a mounting platform 61. The noise testing mechanism 60 is fixedly connected to the mounting platform 61 and abuts against the steering motor. The noise testing mechanism 60 is used to test the abnormal sound or noise of the steering motor during rotation. To ensure its quietness and stability during operation. Bearing wear, internal friction of the motor, electromagnetic interference, etc. may all cause abnormal sound or noise of the motor. The noise testing mechanism 60 can timely discover and diagnose problems in the operation of the motor by performing strict noise tests on the steering motor. At the same time, noise testing can also provide data support for improving the motor to improve the performance and quality of the motor.

[0045] The noise testing mechanism 60 includes a double-hole lock block 1 600, two guide shafts 601, a double-hole lock block 2 602, a mounting plate 1 603, a cylinder 604, a baffle 605, a mounting plate 2 606 and a pressure sensor 607. The double-hole lock block 1 600 is fixedly connected to the mounting platform 61, and the two guide shafts 601 are both detachably connected to the double-hole lock block 1 600. The double-hole lock block 1 600 is used to fix the two guide shafts 601, and the diameter of the guide shaft 601 can be replaced as required. The double-hole lock block 2 602 is slidably connected to the two guide shafts 601. The double-hole lock block 2 602 can be adjusted up and down according to the position of the steering motor to adapt to more requirements. The mounting plate 1 603 is fixedly connected to the double-hole lock block 1 600. The mounting plate 1 603 can be adjusted up and down following the double-hole lock block 1 600. The cylinder 604 is fixedly connected to the mounting plate 1 603, and the mounting plate 2 606 is slidably connected to the cylinder 604. The cylinder 604 is used to adjust the lateral position of the second mounting plate 606, so that it can slide along the slide groove provided on the cylinder 604 to adjust the position of the second mounting plate 606. The baffle 605 is fixedly connected to the second mounting plate 606, and the pressure sensor 607 is fixedly connected to the baffle 605. The baffle 605 is used to fix the pressure sensor 607, which provides convenience for replacing the pressure sensor 607.

[0046] like Figure 9-10 As shown, multiple power-on test mechanisms 8 are used to perform power-on tests on the steering motor. Multiple power-on test mechanisms 8 are respectively located in multiple modules in the production line to complete the power-on tests on the steering motor in multiple modules. The test content includes various parameters such as the start, operation, and stop of the motor.

[0047] The power-on test mechanism 8 includes a power-on test end 80, an axial fixed end 81 and a bracket 2 82. The power-on test end 80 is fixedly connected to the bracket 2 82 and is used to perform a power-on test on the steering motor. When the steering motor needs to be tested on power, the probe seat on the power-on test end 80 will contact the terminal at the tail end of the steering motor, so that the pole piece probe in the probe seat contacts the pole piece probe in the steering motor, thereby powering on the steering motor to rotate. The axial fixed end 81 is used to fix the output shaft of the steering motor. The connecting block at the top of the axial fixed end 81 will be connected to the output shaft of the steering motor. The axial fixed end 81 has a cylinder telescopic function, which can control the lifting and lowering of the connecting block to ensure that the axial fixed end 81 is stably connected to the output shaft of the steering motor.

[0048] Multiple pallet lifting mechanisms 9 are used to control the lifting of pallets. Multiple pallet lifting mechanisms 9 are also installed in multiple modules in the production line to meet the lifting function of the pallets in the multiple modules.

[0049] The tray lifting mechanism 9 includes a lifting plate 90, four linear bearings 91, four guide shafts 92, a lifting module bottom plate 93, a pneumatic module 94 and two pressure plates 95. The four linear bearings 91 are fixedly connected to the lifting module bottom plate 93, the four guide shafts 92 are respectively slidably connected to the four linear bearings 91, and the lifting plate 90 is fixedly connected to the four guide shafts 92. The four guide shafts 92 are arranged at the four corners of the lifting plate 90, and the four linear bearings 91 will drive the guide shafts 92 to move longitudinally, thereby driving the lifting plate 90 to move longitudinally. The two pressure plates 95 are fixedly connected to both sides of the lifting module bottom plate 93. When the tray contacts the two pressure plates 95, the lifting plate 90 stops moving, so that the tray lifting mechanism 9 can limit the position of the tray. It is convenient for other components to test the steering motor. The pneumatic module 94 is detachably connected to the lifting module bottom plate 93, mainly providing a power source for the linear bearings 91.

[0050] The assembly and testing system of the front wheel steering motor also includes a small component installation module 001, a resistance welding module 002, an ion wind cleaning module 003, a shell installation gluing module 004, an airtightness test module 005 and a laser marking machine 006. The small component installation module 001 is used to install small components and glue the motor. When the tray reaches the preset position, the tray lifting mechanism 9 will drive the tray to rise to the specified position, and then manually place the steering motor at the specified position on the tray, read the RFID through the code scanning component, and match the batch information of the steering motor. Then the line body 7 drives the tray and the steering motor to the next station for small component installation. After the small component is installed, exit the grating, start the gluing unit, apply the heat dissipation glue through the three-axis robot arm, and use the camera to detect the gluing effect. Finally, the pressure mechanism is used to make the small component and the steering motor contact closely, and then the small component and the steering motor are tightened by screws and flow to the resistance welding module 002.

[0051] The resistance welding module 002 is located between the small component installation module 001 and the motor relative zero module 1, and is mainly used to weld the components on the steering motor. The steering motor flowing out of the small component installation module 001 enters the resistance welding module 002 for resistance welding. Resistance welding is a method that uses the resistance heat generated by the current passing through the weldment and the contact point as a heat source to locally heat the weldment and pressurize it for welding. Resistance welding does not require filler metal, has high productivity, and small deformation of the weldment.

[0052] The ion wind cleaning module 003 is located after the motor zero module 1, and is mainly used to remove the ion charge generated on the motor, thereby achieving the effect of removing the static electricity of the motor and preventing static electricity from damaging the steering motor. The ion wind mainly blows the small component part to take away the ion charge in the small component, and then the air is sucked out by the lower end vacuum cleaner to take the ion charge away from the ion wind cleaning module 003.

[0053] The shell installation glue coating module 004 is located behind the ion wind cleaning module 003 and is used for sealing and gluing the steering motor.

[0054] The airtightness test module 005 is located after the first temperature abnormal sound test module 6, and is mainly used to test the airtightness of the steering motor. The airtightness test module 005 includes a plugging module and a leak tester. The plugging module is in close contact with the lower end of the steering motor to seal the internal space of the steering motor, and then the airtightness of the steering motor is tested by the leak tester.

[0055] Laser marking machine 006 is used to burn the product logo onto the surface of the steering motor by laser burning. The dust generated by burning is extracted by a vacuum cleaner.

[0056] Working principle: The present invention provides an assembly and testing system for a front wheel steering motor. When in use, the steering motor is first placed manually in a small component installation module 001 to apply heat dissipation glue and install the small component. Then the tray and the steering motor flow into the resistance welding module 002 through the wire body 7, and the components on the steering motor are resistance welded. After welding, the steering motor will enter the motor zeroing module 1, and the output shaft of the steering motor will be zeroed to improve the stability of the steering motor. Further, the steering motor flows into the first temperature test module 2 for performing a first temperature power-on test on the steering motor processed by the motor zeroing module 1 at room temperature. After the test, the steering motor will flow into the ion wind cleaning module 003, and the small component part will be blown by the ion wind to take away the ion charge in the small component, and then the air will be drawn by the lower end vacuum cleaner to take the ion charge away from the ion wind cleaning module 003, thereby achieving the effect of removing the static electricity of the motor and preventing static electricity from damaging the steering motor. Then the shell installation glue coating module 004 seals and glues the steering motor. After the glue coating is completed, the steering motor will enter the second temperature module 3, which will evenly heat the steering motor, and then flow to the second temperature test module 4. The second temperature test module 4 will supplement the heating of the steering motor whose temperature drops to below 80°C, and then test the motor under high temperature conditions. The steering motor that passes the high temperature test will flow to the cooling module 5, and the steering motor will be cooled down to room temperature, and then flow into the first temperature abnormal sound test module 6. The first temperature abnormal sound test module 6 performs a power-on test on the steering motor at room temperature, and at the same time detects the noise it generates, promptly discovers and diagnoses problems during the operation of the motor, so as to improve the performance and quality of the motor. Subsequently, the steering motor flows into the airtight test module 005, and the plugging module is in close contact with the lower end of the steering motor, closing the internal space of the steering motor, and then the airtightness of the steering motor is tested by a leak meter. Finally, the product logo is burned onto the surface of the steering motor by laser burning through the laser marking machine 006.

[0057] Embodiment 2:

[0058] Different from the first embodiment, this embodiment provides a processing system for the small components in the first embodiment. It includes:

[0059] The aluminum base glue coating module is used to apply heat dissipation glue to the aluminum base in the small component. The aluminum base glue coating module includes a glue scraping and glue head centering mechanism, a glue dispensing and visual inspection mechanism. When the tray reaches the specified position, the tray lifting mechanism 9 drives the tray to rise, and the code scanning component scans the tray QR code. Then the aluminum base is loaded and scanned manually. Then the glue dispensing and visual inspection mechanism is started to apply heat dissipation glue to the aluminum base, and the glue dispensing effect is tested.

[0060] Three-board test and installation module, three-board loading is done manually, and then manual horizontal movement is performed. The three boards include a position sensor board, a power board, and a control board. The test is further started, and the three boards are removed after the test, and then the control board is burned in and tested. After the three-board test, the tray flows into the installation station, and the three boards are loaded manually. The tray flows into the M3 screw lock position and rises, and the installation mechanism presses the power board and tightens the screws. Then the tray flows into the M4 screw position, and the installation mechanism grabs the plug for installation, then flips the semi-finished product over, and then continues the installation.

[0061] The cooling and cleaning module includes two cooling lines, a product cleaning mechanism and an XYZ clamping mechanism. The two cooling lines are located on both sides of the product cleaning mechanism and are used to cool the small components before and after cleaning. The product cleaning mechanism is used to clean the small components. The XYZ clamping mechanism is used to flip the small components when cleaning them, so that the dust on the small components can be removed more thoroughly.

[0062] AOI inspection modules are used to detect defects in PCB boards and other electronic components in small assemblies. The core of AOI inspection technology lies in its high speed and high precision, which can quickly detect a large number of electronic components while providing non-contact inspection to avoid damage to the objects being tested. AOI inspection equipment can automatically identify and analyze the inspection results, reduce the interference of human factors, and ensure the stability and accuracy of the inspection results.
