Description

Technical Field

[0001] This utility model relates to the field of automotive parts inspection technology, specifically a visual inspection device for automotive parts production. Background Technology

[0002] The core principle of visual inspection technology is to simulate the human visual system, enabling machines to "see" the appearance of automotive parts and "judge" whether there are defects. In actual operation, a camera first acquires multi-angle, high-resolution images of the automotive parts, and then transmits the acquired images to a computer in the form of digital signals. However, traditional visual inspection equipment is not convenient for adjusting the clamping size of automotive parts of different sizes according to requirements, which can easily lead to positional shifts during clamping, affecting the applicability of the inspection equipment.

[0003] To overcome the aforementioned shortcomings, existing technology (Chinese Patent Publication No. CN113804695A, Publication Date: 2021-12-17) provides an automated visual inspection device for automotive parts. The technical problem this solution aims to solve is that existing automotive parts visual inspection equipment fixes the inspection area of ​​the parts during use, preventing simultaneous inspection of multiple areas and hindering the convenient photographic inspection of the interior of large parts, thus limiting its effectiveness. The proposed automated visual inspection device for automotive parts includes a support frame, a support plate, a visual inspection mechanism, and an electrically driven rotating base. The electrically driven rotating base is rotatably mounted at the bottom center of the support frame, and the support plate is fixedly connected to the upper center of the support frame. The visual inspection mechanism is mounted on the support plate, enabling inspection from different angles and positions, and allowing for inspection of deeper areas within the parts.

[0004] The aforementioned institutions can detect different positions and angles of parts by using detection components. However, in actual use, the position of the parts is prone to shift, which affects the stability of subsequent detection. Utility Model Content

[0005] The purpose of this utility model is to provide a visual inspection device for the production of automotive parts, so as to solve the problem mentioned in the background art that traditional visual inspection devices are not convenient to adjust the clamping size of automotive parts of different sizes according to the needs, which easily causes positional displacement during clamping and affects the applicability of the inspection device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a visual inspection device for automotive parts production, comprising a fixed base plate, a support frame installed at the middle position of the side of the fixed base plate, and a visual inspection component slidably connected to the top of the support frame; a worktable rotatably connected to the middle position of the top of the fixed base plate; clamping mechanisms for limiting the movement of parts are provided at both the front and rear ends of the top of the worktable, the clamping mechanism comprising a threaded rod, the threaded rod being provided at both the front and rear ends of the top of the worktable, movable blocks being threadedly connected to the left and right sides of the outer side of the threaded rod, and a mounting rod being provided at the front end of the movable block, with a clamping plate slidably connected to the inner side of the mounting rod; a drive motor is provided at the bottom end of the fixed base plate, and a rotation mechanism for adjusting the angle of the worktable is provided at the output end of the drive motor.

[0007] Furthermore, a connecting spring is installed at one end of the clamping plate near the movable block, and one end of the connecting spring is connected to the movable block. The clamping plate and the movable block form an elastic structure through the connecting spring.

[0008] Furthermore, the clamping plate has an L-shaped cross-section and is symmetrical about the vertical central axis of the worktable.

[0009] Furthermore, the rotating mechanism includes a drive gear, which is fixedly connected to the output end of the drive motor. The fixed base plate is rotatably connected to a driven gear that matches the drive gear, and the top end of the driven gear is connected to the bottom end of the worktable.

[0010] Furthermore, a dust removal mechanism for cleaning the surface of components is provided on the side of the bottom end of the fixed base plate. The dust removal mechanism includes an elastic airbag, and the elastic airbag is located on the side of the bottom end of the fixed base plate. An air jet is installed on the right side of the elastic airbag through a hose.

[0011] Furthermore, a cam is rotatably connected to the bottom end of the fixed base plate near the side of the elastic airbag, and the outer side of the cam is connected to the outer side of the driven gear through a sprocket transmission mechanism.

[0012] Furthermore, the elastic airbag is provided with a return spring on both the left and right sides, and the return springs are symmetrical about the central axis of the vertical direction of the fixed base plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The motor output drives the sprocket transmission mechanism and the threaded rod to rotate. When the threaded rod rotates, it is threadedly connected to the movable block, allowing the movable block to move outside the threaded rod. When the movable block moves, it simultaneously drives the mounting rod to move. The mounting rod, in turn, drives the connecting spring to clamp and fix the parts. When the parts are large, the clamping plate will be pushed and move towards the movable block. The connecting spring will be simultaneously stressed and shorten its length, allowing the clamping plate to clamp and fix the parts from both ends, increasing the stability during clamping.

[0015] Furthermore, the clamping plate has an L-shaped cross-section, which allows it to keep the edges of the parts in contact and limit their movement when clamping them, thus increasing the stability of the parts when they are clamped.

[0016] Furthermore, during the rotation of the driven gear, the cam can be driven to rotate synchronously through the sprocket transmission mechanism. When the cam rotates, it will squeeze the side of the elastic airbag. When the elastic airbag is squeezed, the gas inside is output through the hose and delivered to the jet nozzle. The jet nozzle can be used to clean the dust from the parts on the workbench surface.

[0017] 2. The output of the drive motor can drive the drive gear to rotate. The drive gear and the driven gear mesh with each other, so that the driven gear will be driven to rotate by the drive gear. The number of teeth on the drive gear and the driven gear are different. Therefore, when the drive gear rotates one revolution, the driven gear deflects a certain angle, so that the worktable above is driven to deflect by the same angle. The parts on the top of the worktable are driven to rotate by the same angle, so that different angles of the parts can be detected by the vision inspection component, thereby ensuring the comprehensiveness of the parts inspection and increasing the applicability during use.

[0018] Furthermore, the sides of the worktable are slidably connected to the fixed base plate, which allows the worktable to rotate more smoothly when driven by the driven gear, thereby effectively preventing the parts from shifting position. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The technical solution shown addresses the problem that traditional vision inspection equipment is inconvenient for adjusting the clamping dimensions of automotive parts of different sizes according to requirements, leading to potential positional shifts during clamping. This vision inspection equipment for automotive parts production discloses a clamping mechanism, including a fixed base plate 1. A support frame 2 is installed at the middle position of the side of the fixed base plate 1, and a vision inspection component 3 is slidably connected to the top of the support frame 2. A worktable 4 is rotatably connected to the middle position of the top of the fixed base plate 1. Clamping devices for limiting the position of the parts are provided at both the front and rear ends of the top of the worktable 4. The clamping mechanism includes a threaded rod 8, which is located at the front and rear ends of the top of the worktable 4. Movable blocks 9 are threadedly connected to the left and right sides of the threaded rod 8. A mounting rod 10 is provided at the front end of the movable block 9. A clamping plate 12 is slidably connected to the inner side of the mounting rod 10. A connecting spring 11 is installed at one end of the clamping plate 12 near the movable block 9, and one end of the connecting spring 11 is connected to the movable block 9. The clamping plate 12 and the movable block 9 form an elastic structure through the connecting spring 11. The cross-section of the clamping plate 12 is L-shaped, and the clamping plate 12 is symmetrical about the vertical central axis of the worktable 4.

[0028] In this example, the parts to be inspected are placed on the surface of the workbench 4. The vision inspection component 3 and the top transmission component work together to inspect the parts on the workbench 4, thus accurately obtaining inspection data. The motor output drives the sprocket transmission mechanism and the threaded rod 8 to rotate. The threaded rod 8 is threadedly connected to the movable block 9 during rotation, allowing the movable block 9 to move outside the threaded rod 8. Simultaneously, the movable block 9 moves the mounting rod 10, which in turn drives the connecting spring 11 to clamp and fix the parts. When the parts are large, this will cause… The clamping plate 12 is pushed and moves towards the movable block 9. The connecting spring 11 is simultaneously stressed and shortens in length, so that the clamping plate 12 can clamp and fix the parts from both ends, increasing the stability during clamping. When the movable block 9 moves, it forms a sliding connection with the worktable 4. The threaded connection between the threaded rod 8 and the movable block 9 allows the movement of the movable block 9 to remain horizontal, preventing angular deviation during movement. The clamping plate 12 has an L-shaped cross-section, which allows it to keep the edges of the parts in contact and limit their movement when clamping them, increasing the stability of the parts during clamping.

[0029] Example 2: Figure 1 , Figure 2 , Figure 3 and Figure 6 The technical solution shown addresses the problem of difficulty in adjusting the inspection angle according to different needs during parts inspection: the visual inspection equipment for automotive parts production discloses a rotating mechanism. A drive motor 5 is installed at the bottom of the fixed base plate 1, and a rotating mechanism for adjusting the angle of the worktable 4 is installed at the output end of the drive motor 5. The rotating mechanism includes a drive gear 6, which is fixedly connected to the output end of the drive motor 5. A driven gear 7 that matches the drive gear 6 is rotatably connected to the fixed base plate 1, and the top of the driven gear 7 is connected to the bottom end of the worktable 4.

[0030] In this example, the output of the drive motor 5 drives the drive gear 6 to rotate. The drive gear 6 meshes with the driven gear 7, causing the driven gear 7 to rotate. The drive gear 6 and the driven gear 7 have different numbers of teeth, so when the drive gear 6 rotates one revolution, the driven gear 7 deflects at a certain angle, causing the worktable 4 above to deflect synchronously. The components at the top of the worktable 4 are also driven to rotate synchronously, allowing the vision inspection component 3 to detect different angles of the components, thus ensuring the comprehensiveness of component inspection and increasing applicability during use. The side of the worktable 4 is slidably connected to the fixed base plate 1, allowing the worktable 4 to rotate more smoothly when driven by the driven gear 7, thereby effectively preventing the components from shifting position.

[0031] Example 3: Figure 1 , Figure 2 , Figure 4 and Figure 6 The technical solution shown addresses the problem of dust residue on the surface of parts causing deviations in inspection data during the part inspection process. The visual inspection equipment for automotive parts production discloses a dust removal mechanism. A dust removal mechanism for cleaning the surface of parts is provided on the side of the bottom end of the fixed base plate 1. The dust removal mechanism includes an elastic airbag 14, which is located on the side of the bottom end of the fixed base plate 1. An air nozzle 16 is installed on the right side of the elastic airbag 14 via a hose. A cam 13 is rotatably connected to the bottom end of the fixed base plate 1 near the elastic airbag 14, and the outer side of the cam 13 is connected to the outer side of the driven gear 7 via a sprocket transmission mechanism. Return springs 15 are provided on both the left and right sides of the elastic airbag 14, and the return springs 15 are symmetrical about the vertical central axis of the fixed base plate 1.

[0032] In this example, the driven gear 7, during its rotation, synchronously drives the cam 13 to rotate via the sprocket transmission mechanism. When the cam 13 rotates, it squeezes the side of the elastic airbag 14. When the elastic airbag 14 is squeezed, the gas inside is output through the hose and delivered to the jet nozzle 16. The jet nozzle 16 can be used to clean the dust from the parts on the surface of the workbench 4. The bottom end of the elastic airbag 14 is provided with an air inlet, and a one-way valve is provided inside the air inlet. Therefore, when the elastic airbag 14 is squeezed to exhaust air, the gas will not be discharged from the air inlet. When the elastic airbag 14 returns to its original position and begins to inhale, the gas enters from the air inlet. At the same time, a one-way valve is provided in the hose connecting the jet nozzle 16 and the elastic airbag 14 to prevent dust from being sucked back from the jet nozzle 16 when the elastic airbag 14 is inhaling air.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
