Description

Technical Field

[0001] This utility model belongs to the field of automobile manufacturing and assembly technology, specifically an automobile caliper error prevention assembly device. Background Technology

[0002] With the continuous development of automobile manufacturing technology, the braking system, as a core component of vehicle safety, faces increasingly higher requirements for assembly precision and reliability. As a critical actuator in the braking system, the automotive caliper's assembly process is highly susceptible to problems such as incorrect, missing, or reversed component installation, which can directly affect braking performance and even lead to serious driving safety hazards. Therefore, on automated or semi-automated caliper assembly lines, there is an urgent need for efficient and reliable error-proofing assembly equipment to ensure the accuracy and consistency of the assembly process.

[0003] A search revealed a patent for a mistake-proof assembly fixture, publication number CN107962366B, published on May 9, 2023. This patent relates to a mistake-proof assembly fixture for ball-pin type parts. It utilizes mechanical detection structures such as neck and thread probes, combined with a PLC control system, to automatically identify and prevent errors in part specifications. When the neck or thread dimensions of the ball pin are incorrect, the probes cannot pass smoothly, the sensor does not receive a signal, the system determines it as an incorrect assembly, and stops subsequent operations. This solution achieves the function of preventing mixed assembly of similar parts and possesses a certain degree of versatility and automation.

[0004] However, this technical solution has significant shortcomings when applied to automotive caliper assembly: First, its detection structure relies on the geometric features of specific parts (such as necks and threads) for matching and judgment. However, automotive calipers have complex structures, including multiple asymmetrical components such as pistons, liners, and brackets. A single probe-type detection method cannot cover multiple types and locations of assembly errors. Second, the device mainly targets the insertion direction and model identification of single shaft parts, lacking the ability to prevent sequential errors and verify positions in multi-station, multi-component collaborative assembly processes. Third, its mechanical probe structure is highly rigid, which can easily interfere with the caliper body during detection, posing a risk of scratching the surface of the parts and making it unsuitable for applications in precision assembly environments.

[0005] A search revealed a hub assembly error-proofing device with publication number CN110681599B, ​​published on November 22, 2024. This patent provides a semi-automatic inspection device based on a combination of a rotating pallet and an error-proofing baffle. By setting steps on the workpiece pallet corresponding to the hub assembly notch, and cooperating with error-proofing blocks on the upper gear sleeve error-proofing baffle, the device enables detection of the hub assembly in either direction. If the hub assembly is reversed, it cannot pass through the passage formed by the error-proofing baffle and is thus rejected by the guide rail. This device has a simple structure and is suitable for directional error-proofing inspection in mass production.

[0006] However, this solution also has significant limitations when applied to automotive caliper assembly: First, the device uses a physical blocking error prevention mechanism, which can only detect whether parts are reversed, and cannot identify complex assembly deviations such as incorrect liner models, improper piston installation, and missing fastening bolts that are common in caliper assembly; Second, its detection method is passive interception, and manual intervention is required to remove mis-assemblies, making it impossible to achieve real-time feedback and automatic correction during the assembly process, which is difficult to meet the requirements of modern intelligent manufacturing for closed-loop control; Third, the equipment is based on a rotating pallet layout, which is suitable for continuous flow inspection of small ring-shaped parts, while automotive calipers are large and heavy, and the assembly process involves multiple steps such as pressing, tightening, and inspection. This structure cannot integrate multiple functional modules, has poor scalability, and is difficult to adapt to the actual process flow of caliper assembly lines.

[0007] The aforementioned problems indicate that existing error-proofing assembly devices are mostly designed for specific types of parts, lacking versatility, employing limited detection methods, and lacking comprehensive judgment capabilities for complex assembly states. This makes it difficult to meet the error-proofing requirements of multi-component, high-precision, and high-safety products such as automotive calipers. Therefore, there is an urgent need for an integrated and intelligent error-proofing assembly device specifically designed for the structural characteristics of automotive calipers. This device should be able to achieve real-time monitoring and automatic intervention at multiple points and with multiple parameters during the assembly process, effectively preventing quality problems such as incorrect or missing assembly, and improving assembly efficiency and product consistency. This utility model aims to provide an automotive caliper error-proofing assembly device to overcome the shortcomings of existing technologies, such as narrow detection range, poor adaptability, and low automation, achieving precise error-proofing control throughout the entire caliper assembly process.

[0023] Specific implementation examples are given below.

[0024] This utility model relates to an automotive caliper error-proof assembly device, the overall structure of which is as follows: Figure 1 As shown in the figure; the equipment mainly includes an assembly platform 1, a positioning device 2, a detection component 7, a verification mechanism 14, a feedback component 21, a rejection mechanism 24, a recycling component 28, a recording module 31, and a support component 33; the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings;

At the same time, the pressure sensor 6 monitors the pressure on the elastic limit block 5 in real time and transmits the data to the control module.

[0026] The detection component 7 is positioned above the positioning device 2.

[0030] The rejection mechanism 24 is located at the bottom of the feedback component 21.

When the caliper is determined to be a defective product, the control module controls the cylinder 25 to start, and the push rod 26 pushes the push plate 27 to remove the defective product from the assembly platform.

[0031] The recycling assembly 28 is located on the side of the rejection mechanism 24. The recycling assembly 28 includes a recycling box 29, which is fixedly installed on the side of the assembly platform 1 by bolts.

The bottom of the recycling box 29 has a discharge port, and a baffle is fixedly connected inside the discharge port. The surface of the baffle is equipped with a handle to facilitate the operator to remove the defective products for subsequent processing.

[0032] The recording module 31 is located on top of the feedback component 21. The recording module 31 includes a memory 32, which is fixedly mounted on the top surface of the assembly platform 1 by bolts. The memory 32 is electrically connected to the control module via a data cable. The surface of the memory 32 is provided with a USB interface, which is electrically connected to an external device via a data cable. The control module stores the data of each test in the memory 32. The operator can export the data via the USB interface for easy quality traceability and data analysis.

[0033] The support assembly 33 is located at the bottom of the assembly platform 1. The support assembly 33 includes a support leg 34, which is fixedly installed at the bottom of the assembly platform 1 by welding. A shock-absorbing pad 35 is fixedly connected to the bottom end of the support leg 34, and the surface of the shock-absorbing pad 35 is provided with anti-slip texture. A reinforcing rib is fixedly connected to the side of the support leg 34, and the other end of the reinforcing rib is fixedly connected to the bottom of the assembly platform 1 to improve the overall stability of the equipment.

[0034] In practical applications, the operator first places the automotive caliper to be assembled into the positioning groove 4. The elastic limit block 5 initially fixes the caliper under the action of the return spring. At the same time, the pressure sensor 6 monitors the installation status of the caliper in real time and transmits the data to the control module. Subsequently, the drive unit 9 drives the lifting rod 10 to descend, so that the detection probe 12 contacts the caliper surface and acquires multi-point assembly information. The camera 13 captures an image of the caliper surface and transmits the data to the image processing module for analysis. Next, the slider 16 slides along the slide rail 15, driving the verification head 18 closer to the caliper. The magnetic sensing element 19 detects the installation status of the internal metal parts of the caliper, and the optical recognition element 2... The system identifies the assembly position of the non-metallic components on the outside of the caliper and transmits the test results to the control module for comprehensive judgment. If the caliper meets the assembly requirements, the control module does not issue an alarm, and the operator can continue to the next step. If the caliper does not meet the assembly requirements, the control module controls the alarm light 22 to issue an alarm, the display screen 23 displays the specific non-conforming information, the cylinder 25 is activated, and the push rod 26 pushes the push plate 27 to remove the non-conforming product from the assembly platform. The non-conforming product slides along the guide plate 30 into the recycling bin 29. The data from each test is stored in the memory 32, and the operator can export the data via the USB interface for easy quality traceability and data analysis. To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the operating principle and implementation steps of this equipment is provided in conjunction with a specific application scenario.

[0035] During the actual assembly process, the operator first places the car caliper to be assembled into the positioning groove 4. At this time, the elastic limit block 5 slides along the guide post under the action of the return spring and applies a certain clamping force to the caliper, thereby achieving initial fixation. At the same time, the pressure sensor 6 embedded on the surface of the elastic limit block 5 monitors the contact pressure between the caliper and the elastic limit block 5 in real time and transmits the collected data to the control module. This process ensures that the caliper is correctly placed in the positioning groove 4 through the sensitive response of the pressure sensor 6, avoiding subsequent detection failure due to position deviation.

[0036] Subsequently, the drive unit 9 is activated, causing the lifting rod 10 to descend, bringing the detection head 11 closer to the caliper surface. The detection probe 12 is fixed in the mounting groove at the bottom of the detection head 11 via a threaded connection. After its tip contacts the caliper surface, it begins to acquire assembly information from multiple points. This information includes, but is not limited to, changes in the height of the caliper surface, hole depths, and bolt tightening status. Simultaneously, the camera 13 embedded in the surface of the detection probe 12 captures images of the caliper surface and transmits the image data to the image processing module for analysis. The image processing module extracts the edge contours and matches features from the captured images to identify whether there are scratches, missing parts, or incorrect installation orientation on the caliper surface. The above detection process, through a combination of mechanical probes and visual recognition, achieves comprehensive coverage of the caliper assembly status.

[0037] During the calibration phase, slider 16 slides along slide rail 15, moving calibration arm 17 above the caliper; calibration head 18 slides on the surface of calibration arm 17 via adjustment block to adapt to the testing requirements of different caliper models; the magnetic sensing element 19 inside calibration head 18 detects the installation status of internal metal parts of the caliper based on the principle of electromagnetic induction, such as whether the piston is in place or whether the liner is correctly assembled; optical recognition element 20 uses changes in reflected light intensity to identify the assembly position of external non-metallic parts of the caliper, such as whether the sealing ring is correctly installed; calibration mechanism 14 transmits the test results to control module, which comprehensively judges whether the caliper meets the assembly requirements;

[0038] If the test results indicate an assembly problem with the caliper, the feedback component 21 is activated; the alarm light 22 emits an alarm signal to alert the operator to the abnormal situation, and the display screen 23 displays specific non-conforming information, such as "piston not in place" or "bolt not tightened"; at the same time, the cylinder 25 in the rejection mechanism 24 is activated, and the push rod 26 pushes the push plate 27 to remove the non-conforming product from the assembly platform 1; the buffer pad on the surface of the push plate 27 effectively reduces the impact on the caliper surface and avoids secondary damage; the non-conforming product slides along the guide plate 30 into the recycling bin 29, completing the automatic rejection process;

[0039] Throughout the entire testing process, the recording module 31 records the data from each test completely through the memory 32. This data includes the readings of the pressure sensor 6, the images captured by the camera 13, and the test results of the calibration mechanism 14. Operators can export the data from the memory 32 via the USB interface for quality traceability and subsequent analysis. In addition, the support legs 34 and the shock-absorbing pads 35 in the support assembly 33 work together to provide stable support for the equipment and reduce the impact of external vibrations on the testing accuracy.

[0040] Through the above steps, this equipment achieves precise error prevention control throughout the entire assembly process of automotive calipers; the positioning device 2 ensures the stable placement of the calipers, the detection component 7 and the verification mechanism 14 conduct comprehensive inspections of the assembly status from mechanical and visual perspectives, respectively, and the feedback component 21 and the rejection mechanism 24 realize real-time feedback and automatic processing of the inspection results; the coordinated work of each component effectively eliminates problems such as incorrect assembly and omissions, and significantly improves assembly efficiency and product consistency.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
