Description

Technical Field

[0001] This utility model belongs to the field of seat foam testing technology, and more specifically, it relates to a device for inspecting the appearance of automotive seat foam. Background Technology

[0002] In the automotive manufacturing industry, car seat foam is a core component of seats, and its quality directly affects the comfort, safety, and lifespan of the seats. As consumers' demands for the quality of car interiors continue to increase, the testing of car seat foam has become particularly important. Currently, the testing of car seat foam covers multiple aspects, including physical performance testing (such as density, hardness, compressive strength, etc.), chemical composition testing (such as harmful substance residues, flame retardant properties, etc.), and appearance quality testing. Among these, appearance quality testing is one of the key steps to ensure that the product meets the factory standards. Its purpose is to detect whether there are defects such as dents, bubbles, cracks, impurities, and uneven color on the foam surface. These defects not only affect the aesthetics of the product but may also indicate potential problems in the internal structure, thereby adversely affecting the overall performance of the seat.

[0003] However, current automotive seat foam appearance inspection processes primarily rely on manual methods. Inspectors need to hold the foam workpiece and rotate it back and forth, visually inspecting every surface of the foam to achieve a comprehensive inspection of its appearance. This manual inspection method has significant limitations: firstly, it is physically demanding for inspectors, and prolonged work can easily lead to visual fatigue, thus affecting the accuracy and efficiency of the inspection; secondly, manual inspection is greatly affected by subjective factors, as different inspectors have different judgment standards and levels of concentration, which may lead to some defects being missed or misjudged. In addition, for automotive seat foam with complex shapes and irregular structures, manual rotation inspection cannot ensure that every minute part is fully observed, making it difficult to effectively guarantee the comprehensiveness and reliability of the inspection. With the increasing scale and automation of automotive seat foam production, this traditional manual inspection method is gradually becoming unable to meet the needs of efficient and accurate inspection.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a car seat foam appearance inspection device in order to achieve a more practical purpose. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an automotive seat foam appearance inspection device, which is achieved by the following specific technical means:

[0006] An appearance inspection device for automotive seat foam includes seat foam. Two sets of first clamping plates and two sets of second clamping plates are respectively provided on the outer wall of the seat foam. The two sets of first clamping plates and two sets of second clamping plates are distributed at equal angles to each other. A clamping electric cylinder is installed at one end of each of the two sets of first clamping plates and two sets of second clamping plates. A first swing gear ring and a second swing gear ring are installed together in pairs of the four sets of clamping electric cylinders. The first swing gear ring and the second swing gear ring are slidably connected. A base is slidably installed on the outer wall of the first swing gear ring. A detection mechanism is provided on the side wall of the base.

[0007] Preferably, the detection mechanism includes a mounting bracket installed on the side wall of the base. The mounting bracket is C-shaped, and a detection camera is installed on the bottom side of one end of the mounting bracket.

[0008] Preferably, the side wall of the first swing gear ring is provided with a connecting protrusion, and the top of the base is provided with a mating groove that matches the connecting protrusion, and the connecting protrusion and the mating groove are slidably connected.

[0009] Preferably, the outer wall of the second swing gear ring is provided with a connecting strip, and the top side of the first swing gear ring is provided with a connecting groove that matches the connecting strip. The second swing gear ring is slidably connected to the first swing gear ring.

[0010] Preferably, a first gear and a second gear are respectively meshed on the bottom and top sides of the first and second swing gear rings, and motors are driven to the side walls of both the first and second gears. The outer walls of the two sets of motors are respectively fixedly connected to the side wall of the base and the side wall of the first swing gear ring.

[0011] Preferably, the clamping surface of the first clamping plate is provided with a flexible cushioning pad, which is made of silicone or polyurethane, and is used to absorb vibration during clamping and avoid indentation on the surface of the seat foam.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model uses a clamping electric cylinder to automatically clamp and fix seat foam, and uses a motor-driven gear to drive a swing gear ring, enabling the foam to perform precise multi-angle rotational movement. With the cooperation of the inspection camera fixed on the C-shaped mounting bracket, it can automatically and comprehensively capture images of all surfaces of the foam, completely replacing the traditional manual hand-held flipping and visual observation method. This significantly reduces the labor intensity of inspection personnel, greatly improves inspection efficiency and coverage, effectively reduces missed detections and misjudgments caused by visual fatigue, subjective factors or complex shapes, and ensures the accuracy and reliability of inspection results.

[0014] 2. This utility model uses alternating clamping control (the second clamping plate is released when the first clamping plate clamps, and vice versa) to ensure that the foam area covered by the current clamping plate is dynamically released during the inspection process. Combined with the rotational movement of the foam, the inspection camera can scan the corresponding surface area without obstruction under different clamping states, completely solving the problem of blind spots caused by clamping tools. The four sets of clamping plates distributed at equal angles always provide symmetrical support force, maintaining clamping stability during alternating switching. The flexible buffer pad design simultaneously avoids indentation on the foam surface during clamping switching, ensuring efficient inspection of the workpiece with zero damage while eliminating blind spots.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example:

[0022] As attached Figure 1 To be continued Figure 3 As shown:

[0023] This utility model provides an appearance inspection device for automotive seat foam, including seat foam 1. The outer wall of seat foam 1 is provided with two sets of first clamping plates 8 and two sets of second clamping plates 16, which are distributed at equal angles to each other. One end of each set of first clamping plates 8 and two sets of second clamping plates 16 is equipped with a clamping electric cylinder 7. The four sets of clamping electric cylinders 7 are jointly equipped with a first swing gear ring 5 and a second swing gear ring 6. The first swing gear ring 5 and the second swing gear ring 6 are slidably connected. A base 2 is slidably installed on the outer wall of the first swing gear ring 5, and an inspection mechanism is provided on the side wall of the base 2.

[0024] The testing mechanism includes a mounting bracket 3 installed on the side wall of the base 2. The mounting bracket 3 is C-shaped, and a testing camera 4 is installed on the bottom side of one end of the mounting bracket 3. The C-shaped mounting bracket 3 design allows the testing camera 4 to flexibly adjust the shooting angle, ensuring full coverage of the surface of the seat foam 1, including the sides and top, avoiding blind spots in manual testing, and improving the integrity of image acquisition and testing efficiency.

[0025] The first swing gear ring 5 has a connecting protrusion 12 on its side wall, and the top of the base 2 has a mating groove 13 that matches the connecting protrusion 12. The connecting protrusion 12 and the mating groove 13 are slidably connected. Through the sliding engagement between the connecting protrusion 12 and the mating groove 13 on the base 2, the first swing gear ring 5 can rotate stably in the horizontal direction, ensuring that the seat foam 1 rotates smoothly during the detection process, reducing image blurring caused by mechanical vibration, and improving detection accuracy.

[0026] The outer wall of the second swing gear ring 6 is provided with a connecting strip 14, and the top side of the first swing gear ring 5 is provided with a connecting groove 15 that matches the connecting strip 14. The second swing gear ring 6 is slidably connected to the first swing gear ring 5. The second swing gear ring 6 slides with the connecting groove 15 of the first swing gear ring 5 through the connecting strip 14, so as to realize multi-angle adjustment in the vertical direction, so that the seat foam 1 can complete compound movements such as pitching and flipping, and completely eliminate the surface obstruction problem caused by fixed clamping in traditional testing.

[0027] The first swing gear ring 5 and the second swing gear ring 6 are respectively fitted with a first gear 9 and a second gear 10 on their bottom and top sides. The side walls of the first gear 9 and the second gear 10 are connected to motors 11. The outer walls of the two sets of motors 11 are fixedly connected to the side walls of the base 2 and the side walls of the first swing gear ring 5. The first gear 9 and the second gear 10 are driven by independent motors 11 to realize synchronous or step-by-step control of the first swing gear ring 5 and the second swing gear ring 6, ensuring that the rotation angle is accurately adjustable, meeting the multi-dimensional detection needs of complex-shaped foams, and improving the flexibility of automated detection.

[0028] The clamping surface of the first clamping plate 8 is provided with a flexible buffer pad. The flexible buffer pad is made of silicone or polyurethane and is used to absorb vibration during clamping and avoid indentation on the surface of the seat foam 1. The flexible buffer pad made of silicone or polyurethane absorbs mechanical impact during clamping and avoids indentation or scratches on the surface of the seat foam 1 by the clamping plate 8. At the same time, it provides stable clamping force, taking into account both protection and fixation reliability, and ensuring zero damage during the testing process.

[0029] The working principle of this embodiment is as follows: Symmetrical clamping: The seat foam 1 is placed between four sets of equal-angled first clamping plates 8 and second clamping plates 16. The clamping plates are synchronously clamped by the clamping electric cylinder 7. The flexible buffer pad made of silicone / polyurethane absorbs vibration and avoids indentation.

[0030] Alternating clamping control: During the detection process, when the first clamping plate 8 clamps, the second clamping plate 16 is released, and vice versa, dynamically releasing the area covered by the clamping plates to eliminate visual obstruction.

[0031] Composite rotary drive:

[0032] Motor 11 drives the first gear 9 and the second gear 10, which in turn causes the first oscillating gear ring 5 and the second oscillating gear ring 6 to rotate around mutually perpendicular axes.

[0033] Horizontal rotation: The first swing gear ring 5 slides through the mating groove 13 connecting the protrusion 12 and the base 2;

[0034] Vertical rotation: The second swing gear ring 6 is achieved by sliding with the connecting groove 15 of the first swing gear ring 5 through the connecting strip 14;

[0035] No blind spots in inspection: When the foam undergoes multiple complex movements such as pitching, flipping, and circumferential movement, the inspection camera 4 continuously captures surface images, covering the blind spots of traditional manual inspection;

[0036] Image processing: Images captured by camera 4 are transmitted to the control system in real time, and defects such as dents, bubbles, and cracks are automatically identified through algorithms such as edge detection and defect feature matching;

[0037] Results generation: The system outputs an inspection report, marking the location and type of defects. After the inspection is completed, the clamping plate automatically releases, and the workpiece enters the next process.

[0038] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
