Description

Technical Field

[0001] This utility model relates to the field of parts processing, and in particular to an automatic detection system for preventing the misalignment of automotive parts. Background Technology

[0002] An automated inspection system for preventing vehicle component misalignment is used in automobile manufacturing and assembly processes to ensure that vehicle components do not shift during transport. It is primarily applied in industrial automation, particularly in quality control during automobile manufacturing. Misalignment can lead to assembly failures and other problems; misalignment prevention refers to using specific technologies to prevent components from shifting during production, transportation, or assembly. Automated inspection, based on sensors, machine vision, artificial intelligence, or other technologies, monitors, analyzes, and provides feedback on the status of target objects in real time. In the scenario of preventing vehicle component misalignment, this system can quickly identify whether the component's position is correct and issue alarms or take corrective measures when anomalies are detected.

[0003] The process of adjusting the position of parts is quite complex, and there is a method of simply pushing away parts that are in an abnormal position. However, for the parts on the conveyor belt to be stable, the conveyor belt needs to have a high coefficient of friction. This means that during the process of pushing away abnormal parts, the conveyor belt itself is affected, causing other parts to become abnormally positioned. Utility Model Content

[0005] To achieve the above objectives, this utility model provides an automatic detection system for preventing the misalignment of automotive parts, comprising: Base; A conveyor belt assembly is mounted on the base. The conveyor belt assembly includes a drive motor and a conveyor belt driven by the drive motor. The outer surface of the conveyor belt is provided with anti-slip texture. The screening component includes a longitudinal linear drive, a sliding seat, a first camera probe, and a transverse linear drive. The longitudinal linear drive is located at one end of the base in the width direction and along the length direction. The longitudinal linear drive extends and retracts to drive the sliding seat. The transverse linear drive is rotatably mounted on the sliding seat with an adjustable angle. The first camera probe is mounted on the sliding seat corresponding to the conveyor belt assembly. The first camera probe is positioned above the conveyor belt and downwards. The transverse linear drive is inclined and points downstream of the conveyor belt. The controller is electrically connected to the longitudinal linear drive, the first camera probe, and the transverse linear drive; The controller controls the operation of the longitudinal linear drive and the transverse linear drive according to the operation of the first camera probe.

[0006] Furthermore, a reflective first laser sensor is provided on the sliding seat corresponding to the conveyor belt assembly. The first laser sensor is located on the side of the conveyor belt and is horizontally positioned. The position of the first laser sensor in the length direction of the sliding seat is adjustable.

[0007] Furthermore, the position of the first laser sensor in the length direction of the slide block is adjustable.

[0009] Furthermore, a second camera probe is provided on the base corresponding to the conveyor belt assembly. The second camera probe is positioned above the conveyor belt and downwards, wherein the second camera probe is located downstream of the screening assembly in the length direction of the base.

[0020] Reference Figures 1 to 5 In one embodiment of this utility model, an automatic detection system for preventing the misalignment of automotive parts includes: Base 100; A conveyor belt assembly is mounted on the base 100. The conveyor belt assembly includes a drive motor and a conveyor belt 210 driven by the drive motor. The outer surface of the conveyor belt 210 is provided with anti-slip texture. The screening component 300 includes a longitudinal linear drive 310, a sliding seat 320, a first camera probe 330, and a transverse linear drive 340. The longitudinal linear drive 310 is disposed at one end of the base 100 in the width direction and along the length direction. The longitudinal linear drive 310 extends and retracts to drive the sliding seat 320. The transverse linear drive 340 is rotatably disposed on the sliding seat 320. The first camera probe 330 is disposed on the sliding seat 320 corresponding to the conveyor belt assembly. The first camera probe 330 is disposed above the conveyor belt 210 and downwards. The transverse linear drive 340 is inclined and points downstream of the conveyor belt 210. The controller is electrically connected to the longitudinal linear drive 310, the first camera probe 330, and the transverse linear drive 340; The controller controls the operation of the longitudinal linear drive 310 and the transverse linear drive 340 based on the operation of the first camera probe 330.

[0021] In the existing technology, there is a method of directly pushing away parts with abnormal positions. However, in order to keep the parts on the conveyor belt stable, the conveyor belt needs to have a high coefficient of friction. This means that in the process of pushing away abnormal parts, the conveyor belt itself is affected, which causes other parts to be abnormally positioned.

[0022] The automatic detection system for preventing displacement of automotive parts provided by this utility model includes: The base 100 serves as the installation foundation, supporting subsequent components.

[0023] The conveyor belt assembly is mounted on the base 100. The conveyor belt assembly includes a drive motor and a conveyor belt 210 that drives the drive motor. The type and structure of the drive motor are not the focus; the key is that it enables the conveyor belt assembly to function properly. The outer surface of the conveyor belt 210 is provided with anti-slip textures to reduce the possibility of part 010 experiencing abnormal positioning. The specific structure of the anti-slip textures is not the focus; various types of anti-slip structures are acceptable.

[0024] The screening component 300 includes a longitudinal linear drive 310, a sliding seat 320, a first camera probe 330, and a transverse linear drive 340. The longitudinal linear drive 310 is located at one end of the base 100 in the width direction and along its length. The longitudinal linear drive 310 extends and retracts to drive the sliding seat 320. The longitudinal linear drive 310 can be a linear motor or a pneumatic rod, etc., to achieve linear motion. The transverse linear drive 340 is rotatably mounted on the sliding seat 320. The angle between the transverse linear drive 340 and the conveyor belt assembly is adjustable to meet operational requirements. The first camera probe 330 is mounted on the sliding seat 320 corresponding to the conveyor belt assembly. The first camera probe 330 is positioned above the conveyor belt 210 and faces downwards. The first camera probe 330 monitors the position of part 010 on the conveyor belt 210, and the image recognition analysis by the backend controller determines whether the position of part 010 is correct.

[0025] When a part needs to be pushed away, the controller controls the longitudinal linear drive 310 to drive the sliding seat 320 at the working speed of the conveyor belt 210. At this time, the working time and smoothness of the transverse linear drive 340 are optimized. However, part 010 still has an effect along the length of the conveyor belt 210. The transverse linear drive 340 is tilted and positioned downstream of the conveyor belt 210. Therefore, during its operation, the transverse linear drive 340 not only pushes part 010 away laterally but also performs the action of conveying it downwards along with the conveyor belt 210. This minimizes the interaction between part 010 and the conveyor belt 210, avoids abnormal deformation of the conveyor belt 210, and reduces abnormal impact on other parts 010. The angle of the transverse linear drive 340 is adjusted to match the conveying speed of the conveyor belt 210.

[0026] The controller is electrically connected to the longitudinal linear drive 310, the first camera probe 330, and the transverse linear drive 340. The controller controls the operation of the longitudinal linear drive 310 and the transverse linear drive 340 according to the operation of the first camera probe 330. For example, if the first camera probe 330 receives an image signal from part 010 and the controller determines that the position is abnormal, it controls the transverse linear drive 340 to push part 010 away.

[0027] In summary, the controller controls the longitudinal linear drive 310 to drive the sliding seat 320 to move at the working speed of the conveyor belt 210, and the working time and smoothness of the transverse linear drive 340 are optimized. The angle between the transverse linear drive 340 and the conveyor belt assembly is adjustable, and the transverse linear drive 340 is tilted and set downstream of the conveyor belt 210. Therefore, during the operation of the transverse linear drive 340, it not only pushes the part 010 away in the transverse direction, but also performs the action of conveying it downward with the conveyor belt 210. The interaction between the part 010 and the conveyor belt 210 is minimized, abnormal deformation of the conveyor belt 210 is avoided, and abnormal impact on other parts 010 is reduced.

[0028] Reference Figure 1 In one embodiment, a reflective first laser sensor 350 is provided on the sliding seat 320 corresponding to the conveyor belt assembly. The first laser sensor 350 is disposed on the side of the conveyor belt 210 and is horizontally arranged. The position of the first laser sensor 350 in the length direction of the sliding seat 320 is adjustable.

[0029] In this embodiment, the position of the part is detected by a first laser sensor 350 installed on the sliding seat 320, which provides a reference for the working time of the transverse linear drive 340.

[0030] In one embodiment, the position of the first laser sensor 350 is adjustable along the length of the slide block 320.

[0031] In this embodiment, the first laser sensor 350 is configured to be position-adjustable, thereby improving the system's operational flexibility and adaptability.

[0032] Reference Figure 1 In one embodiment, a through-beam second laser sensor 110 is disposed upstream of the screening component 300 along the length direction of the base 100.

[0033] In this embodiment, considering that the first laser sensor 350 is disposed on the sliding seat 320, there is a situation where movement occurs, and it is impossible to monitor the position between each part 010 on the base 100. Therefore, a second laser sensor 110 is disposed on the base 100 to monitor the distance between each part 010.

[0034] In one embodiment, a second camera probe is provided on the base 100 corresponding to the conveyor belt assembly. The second camera probe is positioned above the conveyor belt 210 and downwards, wherein the second camera probe is located downstream of the screening assembly 300 in the length direction of the base 100.

[0035] In this embodiment, the operation of the second camera probe is used to detect whether the screening component 300 has malfunctioned. When the second camera probe detects an abnormal position of part 010, a corresponding alarm is issued.

[0036] In one embodiment, the lateral linear drive 340 is hinged to the slide seat 320.

[0037] In this embodiment, the transverse linear drive 340 is hinged to the sliding seat 320, thereby achieving angle adjustment within the plane. For example, a planar bearing is provided on the sliding seat 320, and the transverse linear drive 340 is mounted on the planar bearing to achieve the hinge effect. Correspondingly, a locking structure is provided on the transverse linear drive 340 so that after the angle is adjusted to the correct position, the angle is fixed by the operation of the locking structure.

[0038] In one embodiment, the lateral linear drive 340 is powered by pneumatic drive or electric motor drive.

[0039] In this embodiment, most workshop environments are equipped with compressed air circuits, so it is convenient to set the transverse linear drive 340 as pneumatic drive; while limiting the power of the transverse linear drive 340 to motor drive, it is only necessary to connect voltage to complete the work.

[0040] In one embodiment, the longitudinal linear drive 310 is a linear motor.

[0041] In this embodiment, the drive motor is set as a linear motor, so that both speed and displacement can be precisely controlled to adapt to the working speed of the conveyor belt assembly.

[0042] In one embodiment, a side conveyor belt assembly is also provided at the other end of the base 100 in the width direction.

[0043] In this embodiment, the side conveyor belt assembly and the conveyor belt assembly are arranged side by side. The part 010 rejected by the screening assembly 300 from the conveyor belt assembly is driven to the side conveyor belt assembly by the transverse linear drive 340 and transferred thereto, thereby avoiding the part 010 from being stuck on the base 100.

[0044] In one embodiment, the anti-slip texture is a stripe structure and / or a raised dot structure.

[0045] In this embodiment, the anti-slip texture is a raised or recessed stripe structure, a raised dot structure, etc., and the size of the raised or recessed texture can be between 0.5 and 2 mm, thereby achieving an anti-slip effect.

[0046] In summary, the automatic detection system for preventing displacement of automotive parts provided by this utility model optimizes the working time and smoothness of the transverse linear drive 340 by controlling the longitudinal linear drive 310 to drive the sliding seat 320 at the working speed of the conveyor belt 210. The angle between the transverse linear drive 340 and the conveyor belt assembly is adjustable, and the transverse linear drive 340 is tilted and positioned downstream of the conveyor belt 210. During the operation of the transverse linear drive 340, it not only pushes the part 010 away in the transverse direction, but also performs the action of conveying it downward with the conveyor belt 210. The interaction between the part 010 and the conveyor belt 210 is minimized, avoiding abnormal deformation of the conveyor belt 210 and reducing abnormal impact on other parts 010.
