Description

Technical Field

[0001] This application relates to the field of refrigerator component transportation technology, specifically to a tooling trolley for transporting the refrigerator shell after the VIP component is attached. Background Technology

[0002] With the rapid development of the refrigerator manufacturing industry over the past few decades, manufacturing plants need to overcome the challenge of improving product appearance and quality. This requires implementing standard technologies at every stage of product manufacturing and innovating to enhance the core value of the refrigerator user experience. In the refrigerator manufacturing process, the refrigerator shell is a crucial and visible part of product quality. Data on its appearance (dents, dents, flatness) is a key monitoring standard upon product warehousing, directly reflecting the user's experience with the appearance of high-end products. It is an important component of enhancing the brand image, taste, and quality of high-end refrigerators.

[0003] VIP (Vacuum Insulation Panel) technology, specifically designed to fit snugly into the refrigerator's casing, represents a significant technological breakthrough in the industry, meeting the demands for high energy efficiency. VIP technology refers to the use of vacuum insulation panels (VIPs) during refrigerator manufacturing, ensuring their tight adhesion to the interior of the refrigerator casing. VIP is a highly efficient insulation material that utilizes the principle of vacuum insulation to provide excellent insulation even with a relatively thin layer, thereby improving the refrigerator's energy efficiency and performance.

[0004] The refrigerator shell with VIP components attached is several times heavier (tens of kilograms) than a standalone refrigerator shell, and the cost also increases dramatically by 500-1000 yuan. However, during transportation, the stressed part is still the refrigerator shell with a wall thickness of 0.3-0.45mm, which makes the refrigerator extremely vulnerable to impacts and damage, resulting in significant economic losses.

[0005] How to achieve stable production and quality of refrigerator shells after fitting VIP components while meeting the requirements of high energy efficiency configuration has become a challenge for the refrigerator industry, and breakthroughs are urgently needed in tooling measures such as transportation protection.

[0006] Therefore, the traditional tooling trolleys used for transporting refrigerator shells are prone to bumping and damaging the refrigerator shells, which is a technical problem that urgently needs to be solved by those skilled in the art.

[0007] The information disclosed in the background section is only intended to enhance the understanding of the background of this application, and therefore may contain information that is not part of the prior art known to those skilled in the art. Utility Model Content

[0008] This application provides a tooling trolley for transporting refrigerator shells after the VIP component is attached, in order to solve the technical problem that traditional tooling trolleys for transporting refrigerator shells are prone to bumping and damaging the refrigerator shells.

[0009] This application provides a tooling trolley for transporting a refrigerator shell that conforms to a VIP component, including:

[0010] A rectangular car frame;

[0011] The trolley frame has an elastic support body and multiple rubber-coated bearing rollers. The top of the trolley frame is a rectangular upper fixing plate. Each of the bearing rollers is installed on the upper fixing plate at equal intervals. The elastic support body is attached to the upper fixing plate except for the bearing rollers.

[0012] Four nylon casters with brake pedals are respectively installed at the four corners of the bottom of the rectangular trolley frame, and the brake pedals of the nylon casters are located on the outside of the wheel body;

[0013] Two pairs of anti-tilt posts are provided, with each pair of anti-tilt posts installed at intervals along the bottom wide side of the rectangular trolley frame and located between the two nylon casters.

[0014] The embodiments of this application, by adopting the above technical solutions, have the following technical effects:

[0015] The tooling trolley for transporting refrigerator shells with VIP components according to this application embodiment is a high-performance tooling trolley, particularly suitable for transporting refrigerator shells with VIP components. The tooling trolley not only improves loading and unloading efficiency and reduces the possibility of bumping the refrigerator shell with VIP components by setting rubber-coated bearing rollers and attaching the elastic support body to the upper fixed plate (excluding the bearing rollers), but also offers high safety, practicality, and reliability, demonstrating good practical application value. This results in high quality stability during handling and transfer of the refrigerator shell with VIP components, leading to less damage, lower overall refrigerator cost, and greater competitiveness. Furthermore, the reasonable arrangement of the anti-tipping pillars and brake pedal position makes braking locking and unlocking operations more convenient and quick for operators, eliminating the need to bypass or pay special attention to the anti-tipping pillars, thereby improving the overall operating experience and work efficiency. In addition, the tooling trolley for transporting refrigerator shells with VIP components has a simple structure, low cost, and can be used in batches. Attached Figure Description

[0023] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0024] Example 1

[0025] like Figure 1 As shown in the embodiment of this application, the tooling trolley for transporting the refrigerator shell after attaching the VIP component includes:

[0026] A rectangular car frame;

[0027] The trolley frame has an elastic support body and multiple rubber-coated bearing rollers 6. The top of the trolley frame is a rectangular upper fixing plate 4. Each of the bearing rollers 6 is installed on the upper fixing plate 4 at equal intervals. The elastic support body is attached to the upper fixing plate except for the bearing rollers.

[0028] Four nylon casters 1 with brake pedals are respectively installed at the four corners of the bottom of the trolley frame, and the brake pedals of the nylon casters 1 are located on the outside of the wheel body of the nylon casters 1. Figure 1 The nylon caster wheel 1 is shown schematically, but the details of the brake pedal are not shown.

[0029] Two pairs of anti-tilt posts 2 are installed at intervals on the bottom wide side of the rectangular trolley frame and between the two nylon casters 1.

[0030] The tooling trolley for transporting the refrigerator shell after VIP assembly attachment in this embodiment has a rectangular trolley frame. Multiple rubber-coated bearing rollers are evenly spaced on an upper fixing plate. The refrigerator shell after VIP assembly attachment is placed on the bearing rollers 6 for transport. The bearing rollers provide uniform support points for the refrigerator shell after VIP assembly attachment, ensuring its stability during transport. Simultaneously, the rubber coating of the bearing rollers has good shock absorption performance, effectively reducing the impact on the refrigerator shell after VIP assembly attachment caused by uneven ground or vibration during movement.

[0031] When the rubber-coated bearing roller 6 comes into contact with the refrigerator shell 10 after the VIP components are attached, it can avoid scratches or damage caused by direct metal contact. It is especially suitable for the refrigerator shell 10 after the VIP components are attached, preventing the insulation material from falling off or the appearance of the refrigerator shell from being damaged due to external force, and improving the product transfer yield.

[0032] The bearing rollers can rotate freely under external force. The design of the bearing rollers allows them to rotate freely when subjected to external force. This means that when the refrigerator shell is placed on the tooling trolley after VIP assembly attachment, the bearing rollers can rotate along with the movement of the refrigerator shell. This low-friction motion greatly reduces resistance during handling, making operation easier and improving the overall efficiency of handling the refrigerator shell after VIP assembly attachment.

[0033] Because the bearing rollers can rotate freely, they can support and assist in the movement of the refrigerator shell after the VIP assembly is attached, without damaging it. This avoids surface scratches caused by direct dragging and ensures that product quality is not affected. In addition, the bearing roller structure allows the refrigerator shell to slide or be pushed easily on the tooling trolley after the VIP assembly is attached, reducing the difficulty of manual handling.

[0034] The elastic support body is attached to the upper fixed plate, except for the bearing roller. The cushioning effect of the elastic support body not only improves the loading and unloading efficiency, but also reduces the possibility of bumping the refrigerator shell after the VIP component is attached.

[0035] Four nylon casters with brake pedals are installed at the four corners of the bottom of the rectangular trolley frame, ensuring that the tooling trolley can move flexibly in different directions. The brake pedals of the nylon casters are located on the outside of the wheel body, that is, the brake pedals face outwards, which makes it convenient for the operator to step on the brake pedal to quickly position and lock the trolley, improving the convenience and safety of operation.

[0036] A pair of anti-tilt posts are installed at the bottom wide side of the rectangular trolley frame, between the two nylon casters. This effectively prevents the trolley from tilting during load transport, especially on uneven ground or during emergency braking. It avoids the refrigerator shell shifting and causing collisions due to sudden braking after it has come into contact with the VIP components, significantly improving safety and stability. Furthermore, an anti-tilt post and a nylon caster with a brake pedal are installed at each corner of the trolley frame's bottom, with the brake pedal facing outwards. The anti-tilt post is installed inside the caster, avoiding interference with the brake pedal. This prevents the operator from accidentally hitting the anti-tilt post while trying to press the brake pedal, thus avoiding unnecessary foot injuries. This ensures the effectiveness of the braking function while reducing unnecessary safety hazards. By rationally arranging the positional relationship between the anti-tilt pillars and the brake pedal, operators can perform brake locking or unlocking operations more conveniently and quickly, without having to go around or pay special attention to the presence of the anti-tilt pillars, thereby improving the overall operating experience and work efficiency.

[0037] In summary, the tooling trolley for transporting refrigerator shells with VIP components according to this application embodiment is a tooling trolley with excellent comprehensive performance, especially suitable for transporting refrigerator shells with VIP components. The tooling trolley not only improves loading and unloading efficiency and reduces the possibility of bumping the refrigerator shell with VIP components by setting rubber-coated bearing rollers and attaching the elastic support body to the upper fixed plate (excluding the bearing rollers), but also has high safety, practicality, and reliability, making it highly valuable in practical applications. This ensures high quality stability during handling and transfer of the refrigerator shell with VIP components, resulting in less damage to the refrigerator shell, lower overall refrigerator cost, and greater competitiveness. Furthermore, the reasonable layout of the anti-tipping pillars and brake pedal position makes it more convenient and faster for operators to perform brake locking or unlocking operations without needing to bypass or pay special attention to the anti-tipping pillars, thereby improving the overall operating experience and work efficiency. In addition, the tooling trolley for transporting refrigerator shells with VIP components has a simple structure, low cost, and can be used in batches.

[0038] During implementation, such as Figure 1 As shown, the portion of the upper fixing plate, excluding the bearing roller, is attached to the elastic support body slightly higher than the rubber-coated bearing roller 6, so that the elastic support body on the refrigerator shell above the bearing roller and the upper fixing plate can be evenly stressed after the VIP assembly is attached.

[0039] Because only the rubber-coated portion of the bearing roller provides elastic support, the compressibility of the elastic support is greater than that of the rubber-coated bearing roller. The portion of the upper fixing plate, excluding the bearing roller, is attached to the elastic support slightly higher than the rubber-coated bearing roller. This ensures that after the VIP assembly is transported and attached, the elastic support on the refrigerator shell above the bearing roller and the upper fixing plate can be evenly stressed.

[0040] During the movement of the tooling trolley, the elastic support on the upper fixed plate and the rubber-coated bearing rollers jointly bear part of the pressure from the refrigerator shell after the VIP components are attached, and distribute it to a larger area of ​​the upper fixed plate, thereby reducing the stress concentration problem caused by the point contact of the bearing rollers and minimizing the risk of bumping the refrigerator shell after the VIP components are attached.

[0041] like Figure 1 As shown in the embodiment of this application, the tooling trolley for transporting the refrigerator shell after attaching the VIP component further includes:

[0042] Two rubber-coated side guardrails are connected to the top of the two long sides of the rectangular trolley frame, and the space between the two side guardrails serves as the inlet and outlet of the refrigerator shell after the VIP assembly is attached.

[0043] Two side guardrails are set along the long side of the trolley frame, forming a channel for the refrigerator shell to enter and exit after the VIP assembly is attached. This can play a good guiding role in the process of the refrigerator shell entering or leaving the tooling trolley after the VIP assembly is attached, preventing deviation or misalignment, and improving loading efficiency and positioning accuracy.

[0044] The rubber-coated structure of the side guardrails has a soft and elastic surface, which effectively cushions any potential impact between the refrigerator shell and the side guardrails after the VIP components are applied, thus protecting the refrigerator shell. The side guardrails also provide physical restraint on both sides of the load-bearing area, effectively preventing the refrigerator from sliding laterally or falling off during the movement of the trolley after the VIP components are applied due to vibration, sudden stops, or tilting, thereby improving operational safety.

[0045] In summary, the rubber-coated side guardrails not only improve the guidance, safety, and adaptability of the tooling trolley for attaching VIP components to the refrigerator shell, but also enhance its practicality and reliability in actual production applications, providing strong support for efficient and damage-free material transfer.

[0046] During implementation, such as Figure 1 As shown, the side guardrail is a round tube side guardrail, and the side guardrail adopts a rounded corner structure.

[0047] The side guardrail adopts a round tube structure combined with a rounded corner design, which can effectively avoid the risk of scratches and bumps caused by sharp corners or edges when in contact with the refrigerator shell or operators after the VIP components are attached, thus protecting the surface quality of the refrigerator shell after the VIP components are attached.

[0048] Compared to square tubes or other irregular cross-section structures, the round tube structure of the side guardrail has higher bending and torsional resistance under stress, and can better withstand the impact and vibration during transportation, ensuring the long-term stable use of the side guardrail and extending the service life of the tooling trolley.

[0049] The rounded corners of the side railings make them more comfortable to hold when pushed or gripped manually, and the absence of sharp protrusions enhances ease of operation and ergonomics.

[0050] Alternatively, the two side guardrails are foldable and connected to the top of the two long sides of the rectangular vehicle frame, and the two side guardrails can be folded outwards.

[0051] The side railings feature a foldable structure, allowing them to be opened outwards when needed to create an unobstructed passage and avoid the possibility of the refrigerator shell bumping into the side railings during loading or unloading after attaching the VIP components.

[0052] The foldable side guardrails can be flexibly adjusted to fit the refrigerator shell of different sizes of VIP components. It is not limited to the transportation of standard width boxes, but can also be used for temporary support of irregular or special-sized products, effectively improving the versatility and adaptability of the tooling cart.

[0053] When interfacing with conveyor lines, robotic arms, or other automated equipment, folding guardrails can provide more open operating space for automated handling devices, reduce the risk of interference, improve system integration and automation, and facilitate the realization of intelligent manufacturing processes.

[0054] During the normal movement of the tooling trolley, the side guardrails remain vertical, serving as a limit and protection to prevent the refrigerator shell from slipping off after being attached to the VIP components; when needed, they can be easily flipped outwards to open, balancing safety and operational flexibility, and avoiding the inconvenience or restrictions caused by traditional fixed guardrails.

[0055] Alternatively, the two side guardrails are welded to the top of the two long sides of the rectangular vehicle frame.

[0056] During the normal movement of the tooling trolley, the side guardrails serve to limit and protect the refrigerator shell from slipping off after the VIP components are attached.

[0057] Example 2

[0058] The tooling trolley for transporting the refrigerator shell after attaching the VIP component in this application embodiment has the following characteristics in addition to those in Embodiment 1.

[0059] like Figure 1 As shown in the embodiment of this application, the tooling trolley for transporting the refrigerator shell after attaching the VIP component includes:

[0060] The upper fixing plate 4;

[0061] The bottom fixing plate 3 and four vertical fixing square steels 7 are arranged in parallel with the top fixing plate 4 and the bottom fixing plate 3 and are respectively welded and fixed to the four vertical fixing square steels 7.

[0062] After the VIP components are attached, the finished refrigerator shell weighs tens of kilograms, which is quite heavy. The upper and lower fixing plates are vertically connected by four vertically fixed square steel bars, forming a stable three-dimensional frame structure. Therefore, it has good bending and torsional resistance, can effectively withstand the heavy weight of the refrigerator shell after the VIP components are attached, and ensures the overall structural stability of the tooling trolley during transportation and operation.

[0063] The upper and lower fixed plates, arranged in parallel, together with the vertical square steel, form a rigid support system, which makes the stress distribution more uniform, avoids local deformation or stress concentration, and thus extends the service life of the tooling trolley. It is suitable for frequent handling and heavy-duty working conditions.

[0064] The upper fixing plate, the bottom fixing plate and the vertical fixing square steel are fixed by welding, which not only ensures a firm connection between the structural components, but also enhances the overall frame's sealing and vibration resistance, making it suitable for long-term use in complex workshop environments.

[0065] In summary, the upper and lower fixing plates are vertically connected by four vertical fixing square steel bars, which not only improves the overall strength and load-bearing capacity of the tooling trolley, but also provides a stable and reliable installation platform for various functional components. This fully meets the safety, stability and compatibility requirements of the refrigerator shell during transportation after the VIP components are attached, and has good engineering application value and promotion prospects.

[0066] In practice, all the nylon casters are located below the bottom fixing plate and do not protrude from the bottom fixing plate;

[0067] The elastic support is also attached to the perimeter of the upper fixing plate;

[0068] The elastic support is also attached to the entire side of the vertically fixed square steel.

[0069] The elastic support is also attached to the perimeter of the bottom fixing plate;

[0070] The elastic support is also attached to the outside of the connector between the side guardrail and the trolley frame.

[0071] The nylon casters are all located below the bottom fixing plate and do not protrude from its edge, making the bottom shape of the entire tooling trolley regular and avoiding interference or jamming problems caused by the outward protrusion of the nylon casters. This improves the passability and compatibility in narrow passages, conveyor line docking areas and automated equipment.

[0072] The elastic support not only adheres to the area of ​​the upper fixed plate except for the bearing roller, but also further covers the perimeter of the upper fixed plate, the entire side of the vertical fixed square steel, the perimeter of the bottom fixed plate, and the outside of the side guardrail and frame connection, achieving multi-directional wrapping protection for the entire tooling trolley structure. This prevents the refrigerator shell from being bumped after the VIP component is attached. In addition, it can also effectively absorb vibrations and impacts from all directions during the movement of the tooling trolley, protecting the refrigerator shell from damage after the VIP component is attached.

[0073] The elastic support covers the outside of the side guardrail and the frame connection, preventing metal parts from being directly exposed, reducing the risk of bumps or scratches to operators during handling or adjustment, while also improving the overall appearance and enhancing the user experience.

[0074] The all-around design of the elastic support organically combines functional protection with structural layout, enabling the elastic support to perform functions such as shock absorption, buffering, and anti-slip while also playing a certain role in structural reinforcement and aesthetic enhancement, thereby improving the overall functional integrity and industrial design level of the tooling trolley.

[0075] In summary, this technical solution, through the rational arrangement of the nylon casters and the comprehensive application of elastic supports to multiple key structural parts, achieves systematic optimization of the structure, function, and safety of the tooling trolley. It significantly enhances the stability, adaptability, and reliability of the trolley during the transportation and attachment of the VIP components to the refrigerator shell, demonstrating good engineering application value and promising prospects for promotion.

[0076] Specifically, the elastic support body uses a high-density sponge block, and the thickness of the high-density sponge block is greater than or equal to 5 mm and less than or equal to 10 mm.

[0077] In practice, the gap between the bottom of the anti-tilting column 2 and the nylon caster 1 is greater than or equal to 10mm and less than or equal to 20mm.

[0078] The interval between the anti-tilting column 2 and the nylon caster 1 installed at the same position is greater than or equal to 50 mm and less than or equal to 100 mm.

[0079] A gap of 10mm to 20mm is maintained between the anti-tilt column and the bottom of the nylon caster, ensuring that the gap between the anti-tilt column and the bottom surface is greater than or equal to 10mm and less than or equal to 20mm. This effectively prevents the risk of forward tilting or tipping over due to uneven ground or emergency braking, while maintaining the normal movement and turning flexibility of the tooling trolley. This gap avoids interference between the anti-tilt column and the nylon caster, and provides support in critical moments, enhancing the safety and stability of equipment operation.

[0080] The lateral spacing between the anti-tilt column and the nylon caster is controlled within the range of 50mm to 100mm to ensure that the two will not collide or rub against each other under stress, while the anti-tilt column can effectively constrain the overall center of gravity of the trolley.

[0081] In practice, the length of the bearing roller 6 is greater than or equal to 1000 mm and less than or equal to 1200 mm.

[0082] The interval between the bearing rollers 6 is greater than or equal to 5 mm and less than or equal to 30 mm.

[0083] In practice, the distance between the upper fixing plate 4 and the bottom of the nylon caster 1 is greater than or equal to 450mm and less than or equal to 550mm.

[0084] The height of the side guardrail 5 is greater than or equal to 100mm and less than or equal to 300mm.

[0085] The bearing roller length is set in the range of 1000mm to 1200mm, which can effectively support the refrigerator shell of the current mainstream specifications, especially the refrigerator shell after the VIP component is attached, to ensure that the bottom of the refrigerator shell is evenly stressed and the load is stable, adapting to the transportation needs of various models of products and enhancing the compatibility and applicability of the tooling trolley.

[0086] The bearing rollers are of moderate length, ensuring sufficient support area while avoiding structural redundancy caused by excessive length. This helps to distribute the weight of the refrigerator shell after the VIP components are attached reasonably across multiple bearing rollers, reducing single-point pressure and preventing the refrigerator shell from being bumped due to uneven force, thus improving safety during transportation.

[0087] A gap of 5mm to 30mm is set between the bearing rollers to ensure smooth sliding of the refrigerator shell on the bearing rollers after the VIP assembly is attached. This gap design avoids friction interference caused by overly dense bearing rollers, achieving an organic combination of smooth rolling and flexible support.

[0088] like Figure 1 and Figure 2As shown, in the two embodiments of this utility model, the tooling trolley for transporting the refrigerator shell after attaching the VIP component needs to be transferred to the chain conveyor 11 for subsequent processes after transporting the refrigerator shell after attaching the VIP component to a preset position. Therefore, the upper surface of the bearing roller 6 of the tooling trolley for transporting the refrigerator shell after attaching the VIP component is flush with the upper surface of the chain conveyor 11 to achieve smooth transfer of the refrigerator shell after attaching the VIP component.

[0089] This utility model presents two embodiments of a tooling trolley for transporting refrigerator shells with VIP components attached, solving the problem of reliable transport quality for such trolleys. For each refrigerator shell transported with VIP components attached, waste can be reduced by approximately 500-1000 yuan, ultimately improving transport quality and reliability issues such as waste.
