Description

Technical Field

[0001] This application relates to the field of automotive component assembly equipment, and particularly to an automatic assembly device for automotive backrest motors. Background Art

[0002] In the context of the rapid development of the automotive manufacturing industry, the performance and comfort of automotive seats have become one of the core elements that consumers focus on. As an important part of enhancing seat functions, the assembly process of automotive backrest motors directly affects the overall quality of the seats and the user experience. In recent years, with the continuous growth of market demand and technological progress, the automotive industry has an increasingly urgent need for high-precision and efficient assembly equipment, which has promoted the research and application of related technologies, further improving production efficiency and product quality.

[0003] In the traditional manual assembly mode, in order to ensure the accurate installation of automotive backrest motors, manual alignment of holes is usually adopted, and positioning and locking operations are completed through bolts or other fixing parts. Specifically, common methods include using jigs for auxiliary positioning, manual adjustment, and visual inspection. In addition, there are semi-automatic means of preliminary fixation through simple mechanical devices, such as using pneumatic or hydraulic tools to apply pressure for temporary fixation. Although these methods can meet the basic assembly requirements to a certain extent, there are still many limitations in actual applications.

[0004] The main problems of the above traditional assembly methods are low efficiency and susceptibility to human factors. Especially in the face of mass production, it is easy to cause assembly errors or even part damage due to improper operation. Especially in the assembly process of automotive backrest motors, since multiple holes need to be accurately aligned, and the balance and stability on both sides need to be ensured at the same time, the traditional single-sided positioning or middle positioning methods often cannot completely avoid the risk of motor loosening or falling off, thus affecting the reliability and consistency of the final product. Therefore, how to improve assembly accuracy and reduce human errors has become an urgent technical problem to be solved. Summary of the Invention

[0036] Refer to Figure 7 , the printing assembly 6 includes a mounting frame 61 provided on the frame 1, a placement box 62 is provided on the mounting frame 61, and a printer 63 is provided in the placement box 62.

[0037] Refer to Figure 8 , the oil wiping assembly 7 includes an oil barrel 71 provided on the frame 1, a cover body 72 is provided at the top of the oil barrel 71, the cover body 72 and the oil barrel 71 are connected in a sealed manner, a knob switch 73 is mounted on the cover body 72, the knob switch 73 is communicated with the oil outlet channel inside the oil barrel 71, and by rotating the knob switch 73, the opening or closing of the oil outlet channel of the oil barrel 71 can be conveniently controlled.

[0038] Specifically, when performing the assembly operation of the automotive backrest motor: First, in the preparation stage, the operator moves the car backrest 8 to be assembled to the top of the central positioning component 2. At this time, all components are in the initial state, such as the cylinder piston rods are retracted, the slide rail slider is in the initial position, etc.

[0039] Next, the backrest positioning operation begins. The backrest 8 is gently placed on the base 21 of the neutral positioning assembly 2. The first drive cylinder 224, receiving instructions from the control system, begins operation. Its piston rod extends, pushing the first guide block 222 to slide along the first guide rail 221, driving the first mounting plate 223 and its upper components toward the backrest 8, achieving initial coarse lateral positioning. Simultaneously, the fourth drive cylinder 234 also operates synchronously, driving the fourth guide block 232 to slide along the fourth guide rail 231, driving the second fixing plate 233 to approach the backrest 8 from the other side, achieving coarse lateral positioning on the other side.

[0040] When both sides are approximately aligned, the second drive cylinder 228 is activated, pushing the second guide block 226 along the second guide rail 225. This allows the first locating pin 229 on the first fixing plate 227 to precisely insert into the corresponding locating hole on the vehicle backrest 8, completing the initial positioning. The first receiving seat 2210 then fits snugly against the corresponding portion of the vehicle backrest 8, providing stable support. Simultaneously, the second locating pin 235 on the second fixing plate 233, coordinated by the subsequent action of the fourth drive cylinder 234, also inserts into the corresponding locating hole, providing support from the second receiving seat 236. Finally, the second drive cylinder 228 is further actuated, driving the first fixing plate 227 toward the pressure plate 2212. Together with the pressure plate 2212, they securely clamp the vehicle backrest 8 from both sides, ensuring it remains stationary during subsequent assembly. Similarly, the fourth drive cylinder 234 drives the second fixing plate 233, which cooperates with the second cylinder mounting plate 237 to securely clamp the other side. The vehicle backrest 8 is now precisely and stably secured to the center positioning assembly 2.

[0041] Then, the motor installation phase begins. The secondary clamping assembly 3 begins to operate, and the fifth drive cylinder 34 is activated according to the preset program. The piston rod extends to push the first X-axis slider 32 to slide along the first X-axis slide rail 31, quickly adjusting the lateral position of the third mounting plate 33 so that it is close to the predetermined position on one side of the car backrest 8. Immediately afterwards, the sixth drive cylinder 38 works, driving the first Y-axis slider 36 to slide along the first Y-axis slide rail 35, driving the fourth mounting plate 37 to achieve longitudinal position adjustment, ensuring that the first feed rod 311 is aligned with the part to be clamped on one side of the car backrest 8. At this time, the seventh drive cylinder 310 is activated, and the piston rod extends to push the first feed rod 311 to move toward the car backrest 8. The rubber sleeve 313 first contacts the car backrest 8, which not only cushions the impact force to avoid damaging the backrest, but also provides sufficient friction, so that the first feed rod 311 firmly supports one side of the car backrest 8.

[0042] Meanwhile, the washer pressing component 4 also works in coordination. The eighth driving cylinder 44 drives the second X-axis slider 42 to slide along the second X-axis slide rail 41, driving the fifth mounting plate 43 to adjust to a suitable lateral position, so that the second feeding rod 47 aligns with the motor mounting part on the other side of the car backrest 8. Subsequently, the ninth driving cylinder 46 is activated, pushing the second feeding rod 47 towards the car backrest 8. The external air source connected to the air pipe joint 48 provides stable air pressure, enabling the second feeding rod 47 to firmly press and install the motor 9 and the washer together onto the other side of the car backrest 8. With the close cooperation of the secondary pressing component 3 and the washer pressing component 4, the motor 9 is accurately and firmly installed on the car backrest 8, with uniform force on both sides, effectively avoiding the risk of the motor loosening or falling off.

[0043] After the motor installation is completed, the detection stage immediately begins. The slide cylinder 53 of the vision component 5 receives the instruction and starts, driving the camera 54 on the slide. Through the vertical adjustment range provided by the mounting column 52 and the horizontal movement ability of the slide cylinder 53 itself, the camera 54 can take pictures of the installation position of the motor 9 from all directions and at multiple angles. The captured images are transmitted to the control system in real time, and the image recognition algorithm is used to accurately analyze the position, angle, and cooperation with surrounding components of the motor 9 to determine whether the motor 9 is installed in place and whether there are any deviations. If a problem is detected, the control system will issue an alarm and prompt the operator to make adjustments or re-assemble, ensuring that each assembled car backrest motor meets the quality requirements, greatly improving the detection accuracy and efficiency, and avoiding the subjectivity and limitations of manual visual inspection.

[0044] Finally, after the motor 9 is assembled and passes the inspection, the printing component 6 comes into play. The printer 63 receives the printing instruction from the control system and prints out labels or reports containing key data such as assembly information (such as motor model, installer number, etc.), product batch, date, etc. The operator can paste or file these labels or reports, which is convenient for subsequent quality traceability, inventory management, and production process control, effectively improving the information management level of the entire production link.

[0045] During the entire assembly process, when lubrication and maintenance are required for some moving parts such as the transmission shaft on the car backrest 8, the operator only needs to gently rotate the knob switch 73 of the oiling component 7 to open the oil outlet channel of the oil barrel 71, and insert the transmission shaft into the oil barrel to apply the lubricant to the corresponding parts as needed. After the operation is completed, rotate the knob switch 73 again to close the oil outlet channel, simply and conveniently controlling the use of lubricating oil, ensuring good lubrication of the equipment, extending the service life of the equipment, and optimizing the assembly process.

[0046] Embodiment 2. In this embodiment, based on the above basic structure, the following new technical features are added: A piezoelectric ceramic sensor is embedded at the end of the first feeding rod 311 of the secondary pressing assembly 3 to monitor the pressure when the first feeding rod 311 contacts the car backrest 8 in real time. At the same time, a pressure sensor is installed at the air pipe joint 48 of the gasket pressing assembly 4 to monitor the air pressure exerted by the second feeding rod 47 on the motor 9 in real time, and thus indirectly reflect the pressing force on the motor 9 and the car backrest 8. A PID controller is set up, which can dynamically adjust the outputs of the seventh driving cylinder 310 and the ninth driving cylinder 46 according to the data fed back by the above two sensors (the seventh driving cylinder 310 adjusts the pressure of the first feeding rod 311, and the ninth driving cylinder 46 cooperates to adjust the air pressure of the air pipe joint 48). The output pressure of the seventh driving cylinder 310 can be flexibly adjusted between 0.5 - 5 MPa, and the air pressure of the air pipe joint 48 can be accurately controlled correspondingly by the cooperation of the ninth driving cylinder 46. In addition, the pressing force-related data collected by the two sensors are synchronously transmitted to the vision system. Combining with the images captured by the camera 54 in the vision system, a pressure distribution heat map is generated using a dedicated image processing algorithm.

[0047] During the specific operation process, when starting to install the motor 9, the first feeding rod 311 of the secondary pressing assembly 3 moves towards the car backrest 8. The second feeding rod 47 of the gasket pressing assembly 4 moves towards the motor 9 under the action of the external air source connected to the air pipe joint 48 and is ready to press it against the other side of the car backrest 8. At this time, the piezoelectric ceramic sensor at the end of the first feeding rod 311 immediately starts to work, senses the pressure when contacting the car backrest 8, and transmits the pressure signal to the PID controller in real time. At the same time, the pressure sensor at the air pipe joint 48 also synchronously collects the air pressure data, converts it into the corresponding pressing force data, and then transmits it to the PID controller.

[0048] The PID controller has pre-set the optimal pressing force parameters for different car backrest materials (for example, the fabric backrest is relatively soft, and the leather backrest is harder) and motor types. When receiving the real-time pressure feedback, the PID controller will quickly perform calculations and analyses. If it is found that there is a deviation between the actual pressure and the preset pressure, it will promptly adjust the outputs of the seventh driving cylinder 310 and the ninth driving cylinder 46. For example, for a soft fabric backrest, the PID controller will appropriately reduce the output pressure of the seventh driving cylinder 310 to avoid over-squeezing and damaging the backrest by the first feeding rod 311; at the same time, it will accurately adjust the ninth driving cylinder 46 correspondingly to control the air pressure of the air pipe joint 48, so that the second feeding rod 47 presses the motor 9 with an appropriate force. For a harder leather backrest, the output pressure of the fifth driving cylinder 34 will be increased, and at the same time, the air pressure of the air pipe joint 48 will be adjusted to ensure the firm installation of the motor 9, thus avoiding the problem of pressing failure caused by material differences.

[0049] Meanwhile, the data related to the pressing force collected by the two sensors is synchronously transmitted to the vision system. The vision system combines the received pressure data with the images captured by the camera 54 and generates a pressure distribution heat map through a dedicated image processing algorithm. In this heat map, different colors represent different pressure magnitudes, and the operator can intuitively see the distribution of the pressing force at various parts of the car backrest 8 and the motor 9 during the assembly process. By observing the heat map, the operator can promptly detect abnormal pressure areas, such as areas with excessively high or low local pressure, and take corresponding adjustment measures to further monitor and ensure the assembly quality. Through this intelligent pressure compensation pressing system, the qualified rate of motor installation is improved. At the same time, due to the precise control of the pressing force, the wear of the mold caused by improper pressure is reduced, the risk of mold wear is lowered, and the service life of the mold is extended, providing a strong guarantee for long-term stable production.

[0050] Example 3. In this example, an upgrade is made on the basis of the original device, and the new technical features are as follows: the vision component 5 is upgraded to an industrial camera (with a resolution of 5 million pixels) + a multi-spectral light source, and an edge computing module is added to the mounting base plate 51. Special algorithms are developed: ① motor installation position recognition based on CNN; ② detection of bearing vibration anomalies through FFT analysis; ③ OCR recognition of whether the motor code meets the model requirements.

[0051] When conducting the quality inspection of motor installation, first of all, with the assistance of the multi-spectral light source, the high-resolution industrial camera can capture clearer and more delicate image details of the motor 9 and its surrounding components. Compared with ordinary cameras, the image recognition rate is greatly improved. On the one hand, these image data are transmitted to the edge computing module on the mounting base plate 51, and the motor installation position recognition algorithm based on CNN is used to quickly and accurately judge whether the installation position of the motor 9 on the car backrest 8 is accurate, and it can identify assembly deviations at the 0.1 mm level (the prior art usually only detects cases where the position offset is ≥ 0.5 mm); on the other hand, through FFT analysis of the vibration signal collected during the operation of the motor 9, bearing vibration anomalies can be detected in a timely manner, and potential quality hazards can be warned in advance; at the same time, using OCR recognition technology, the code on the surface of the motor 9 is read and compared with the preset model requirements to ensure that the installed motor model is correct.

[0052] Example 4. In this example, the device structure is changed as follows: the frame 1 adopts a quick-release truss structure, and modules such as the median positioning component 2 and the secondary pressing component 3 are connected by magnetic pins. Standardized interfaces (including power supply / gas circuit / data bus) are configured, and no tools are required when replacing different functional modules, and the production line can be switched within 15 minutes.

[0053] When it is necessary to switch to the production of different components, for example, from the assembly of automotive seatback motors to the assembly of steering wheel adjustment motors, the operator only needs to first disconnect the connection between each module and external equipment, and then simply operate to pull out the magnetic pins to quickly disassemble the original modules such as the median positioning component 2 and the secondary pressing component 3. Then, the corresponding modules specially designed for the assembly of the steering wheel adjustment motor can be easily inserted and fixed on the frame 1 according to the identification of the standardized interface, connect the power supply, air circuit and data bus, and the entire production line can be switched within just 15 minutes. This modular quick-change assembly platform enables the same equipment to be compatible with the assembly of various components such as seat motors and steering wheel adjustment motors, improves the equipment utilization rate, is suitable for the production scenario of multiple varieties and small batches, effectively reduces the equipment investment cost of the enterprise, and improves the flexibility and adaptability of production.

[0054] Example 5. The new technical features added in this example are as follows: Absolute value encoders are installed at the key nodes of the frame 1 (such as guide rail sliders and cylinder piston rods), and the "full stroke calibration program" is automatically executed when the machine is first started. When the repeat positioning error exceeds the threshold, the system triggers an audible and visual alarm and records the fault code, and at the same time pushes a maintenance work order to the MES system.

[0055] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
