Description

Technical Field

[0001] This utility model relates to the field of electrical manufacturing technology, and in particular to a reversing device for refrigerator assembly. Background Technology

[0002] On a refrigerator assembly line, refrigerators typically undergo multiple assembly processes sequentially along a conveyor belt. In some assembly steps, due to limitations of upstream processes or structural installation requirements, the refrigerator needs a 90° directional adjustment before entering the next process to facilitate manual or automated assembly. Existing technologies often employ rotary reversing mechanisms for this adjustment, using a turntable or robotic arm to rotate the entire refrigerator to the target orientation. These devices are complex, have long operating cycles, and low reversing frequencies, making them unsuitable for continuous and efficient production line operation and easily becoming a bottleneck for improving assembly line efficiency.

[0003] Furthermore, existing rotary reversing mechanisms typically require a dedicated reversing station, occupying significant space. For workshops with fixed production line layouts, it's often difficult to easily modify the existing transport paths to install such mechanisms. Simultaneously, the independent setup of the reversing mechanism increases equipment purchase and maintenance costs, and reduces the overall system integration and stability. Therefore, there is an urgent need for a compact, adaptable refrigerator assembly reversing device capable of continuous reversing operations to improve production line efficiency and meet the flexible manufacturing demands of modern home appliance production.

[0004] Patent "A Reversing Mechanism for a Raw Material Conveying System" (Publication No. CN214298070U, hereinafter referred to as Prior Art 1) discloses a reversing mechanism. Prior Art 1 uses an "L"-shaped reversing system composed of lateral, steering, and longitudinal conveying mechanisms to avoid interference by utilizing height differences. The steering conveying mechanism (a turntable, rollers, and baffles driven by a motor) can rotate 90° to switch the raw material from lateral to longitudinal conveying, thereby extending the conveying path within a limited space. The baffle assembly prevents the raw material from falling during the steering process, achieving safe and efficient conveying direction conversion. However, the reversing mechanism in Prior Art 1 relies on height differences for direction conversion, which is difficult to implement on a refrigerator assembly line due to the large size and weight of refrigerators, making vertical movement difficult. Furthermore, the reversing mechanism in Prior Art 1 is not suitable for the continuous and efficient operation of an assembly line, and its reversing efficiency and system integration still need improvement.

[0028] Example 1

[0029] Please see Figure 1 This utility model provides a reversing device for refrigerator assembly; on a refrigerator assembly production line, the refrigerator completes multiple assembly processes sequentially along the conveyor line. In some assembly processes, due to limitations of upstream processes or structural installation requirements, the refrigerator must undergo a 90° directional adjustment before entering the next process to facilitate manual or automated assembly operations.

[0030] In existing technologies, rotary reversing mechanisms are typically used to adjust direction, that is, the refrigerator as a whole is rotated to the target direction by a turntable or rotary robotic arm. These devices have complex structures, long operation cycles, and low reversing frequencies, making it difficult to meet the needs of continuous and efficient production line operation, and easily becoming a bottleneck for improving production line efficiency. In addition, existing rotary reversing mechanisms usually require an additional dedicated reversing station, occupying a large space. For workshops with relatively fixed production line layouts, it is often not easy to modify the original conveyor path to install such mechanisms.

[0031] In this invention, by cutting off one end of the original conveyor line and setting it as the reversing device, it can be seamlessly connected with the original conveyor line without the need to set up a workstation in an additional area.

[0032] Please see Figure 1 In this embodiment, the reversing device includes a frame 100, a first conveying section 210, and a reversing section 300. The first conveying section 210 is used to convey refrigerators, and a parallel roller group 211 is provided on the first conveying section 210. The reversing section 300 is used to reverse the direction of the refrigerator on the first conveying section 210, and a reversing roller group 310 is provided on the reversing section 300 at an angle. The frame 100 has a reversing auxiliary wheel 112 on one side of one end of the reversing section 300. The first conveying section 210 is connected to the reversing section 300, and the rollers on the parallel roller group 211 and the reversing roller group 310 are connected in a transmission manner to each other. In actual use, the refrigerator is placed on a base for placing refrigerators.

[0033] In use, the refrigerator is smoothly conveyed to the reversing section 300 by the parallel roller group 211 of the first conveying section 210. As the refrigerator enters the reversing section 300 along with its base, the base is abutted by the reversing auxiliary wheel 112 before entering the conveying reversing section 300, thus restricting the movement of the side of the base in contact with the reversing auxiliary wheel 112. When the bottom of the base begins to contact the obliquely arranged reversing roller group 310, the oblique design of the reversing roller group 310 causes the other side of the base to gradually receive a force guiding its direction as the refrigerator continues to move forward. At the same time, the reversing auxiliary wheel 112 provides additional support and guidance on one side of the refrigerator, ensuring that the refrigerator remains stable during the reversing process, avoiding deviation or tipping, and also allowing the refrigerator to rotate against the reversing auxiliary wheel 112. As the base gradually moves forward with the reversing roller group 310, the reversing action is also gradually completed. Because the rollers on the parallel roller set 211 and the reversing roller set 310 are connected in pairs, the entire reversing process is smooth and synchronous, greatly shortening the operation cycle and improving the reversing efficiency. In this way, the refrigerator can quickly and accurately complete a 90° directional adjustment and continue to move along the predetermined conveying path to the next process.

[0034] Please see Figure 1 and Figure 3The frame 100 is further provided with an adjustable limiting plate 113 on the side of the reversing section 300 where the reversing auxiliary wheel 112 is located. The adjustable limiting plate 113 can be adaptively adjusted according to the width of the refrigerator, ensuring that the refrigerator can be effectively restricted and guided during the reversing process, regardless of its size. The design of the adjustable limiting plate 113 allows the operator to easily adjust its position according to actual needs, thereby closely fitting refrigerators of different widths and preventing unnecessary shaking or displacement of the refrigerator during the reversing process. This design further enhances the stability and applicability of the reversing device, making the entire reversing process more precise and efficient. By combining the functions of the reversing auxiliary wheel 112 and the adjustable limiting plate 113, the reversing device in this embodiment can ensure that the refrigerator maintains high stability and accuracy while rapidly reversing, meeting the high efficiency and automation requirements of the production line.

[0035] In use, the adjustable limit plate 113 is adjusted to a suitable position. When the refrigerator base moves from the reversing section 300 and completes the reversal, the rotational force may cause it to tip over to the side it is turning. Therefore, the adjustable limit plate 113 effectively prevents the refrigerator base from tipping over, ensuring the safety of the refrigerator during the reversal process. Simultaneously, the design of the adjustable limit plate 113 also considers the frictional force that may be generated when the refrigerator base reverses. By appropriately adjusting the position of the limit plate, the frictional force can be reduced, allowing the refrigerator base to complete the reversal more smoothly. This detailed design not only improves reversal efficiency but also extends the service life of the reversing device, providing a strong guarantee for the stable operation of the production line.

[0036] Further, please see Figure 1 In this embodiment, the reversing device further includes a second conveying section 220; the first conveying section 210 and the second conveying section 220 are respectively disposed at both ends of the reversing section 300, and are respectively used to send the refrigerator into and out of the reversing section 300.

[0037] In use, the refrigerator is first placed on the first conveyor section 210. As the first conveyor section 210 operates, the refrigerator moves smoothly to the reversing section 300. At the reversing section 300, the refrigerator undergoes the aforementioned reversing process, quickly and accurately completing its turn. After turning, the refrigerator is received by the second conveyor section 220 and smoothly delivered out of the reversing area into the assembly or working area. This design not only achieves continuous flow of refrigerators on the production line but also ensures seamless connection of the reversing process, greatly improving production efficiency. Simultaneously, the stable operation of the first and second conveyor sections 210 and 220 provides strong support for the reliability of the entire reversing device. The reversing auxiliary wheel 112 is mounted on the frame 100 via a mounting plate 111 and protrudes from within the frame 100. When the refrigerator is conveyed to the reversing auxiliary wheel 112 via the first conveyor section 210, the reversing auxiliary wheel 112 abuts against one side of the refrigerator.

[0038] The reversing auxiliary wheel 112 is disposed at the junction of the first conveying section 210 and the conveying reversing section 300, and is disposed at a position in the first conveying section 210 not exceeding the last parallel roller. This allows the base of the refrigerator to first contact the reversing auxiliary wheel 112 and be abutted by the reversing auxiliary wheel 112; and allows the other side of the base to first contact the reversing roller group 310, so that the other side rotates first and then drives the other side into the reversing section 300 for reversal.

[0039] The ingenious design of the reversing auxiliary wheel 112 lies in its dual optimization of position and function. First, its position is precisely set at the junction of the first conveyor section 210 and the reversing section 300, and not exceeding the last parallel roller. This ensures that the refrigerator's base contacts the reversing auxiliary wheel 112 before entering the reversing section 300. This contact not only guides and positions the refrigerator but also, through the abutting force of the reversing auxiliary wheel 112, allows one side of the refrigerator base to smoothly transition to the reversing section 300. Next, the other side of the refrigerator base contacts the reversing roller group 310. This design allows the refrigerator to make a slight rotation around one side as an axis during reversal, thereby driving the entire unit to complete the reversal smoothly and steadily. This design greatly reduces impact and friction during reversal, improving not only the accuracy and stability of reversal but also effectively protecting the refrigerator's appearance and structure, ensuring the continuity and efficiency of the production line.

[0040] Please see Figure 2The reversing roller assembly 310 has a first reversing roller 311 and a second reversing roller 312 at one end near the first conveying section 210. When the refrigerator is conveyed to the reversing section 300 via the first conveying section 210, the refrigerator sequentially contacts the first reversing roller 311, the second reversing roller 312, and the reversing roller assembly 310 to complete the reversing operation. The lengths of the first reversing roller 311, the second reversing roller 312, and the reversing roller assembly 310 increase progressively.

[0041] In operation, the refrigerator first contacts the first reversing roller 311. This roller is relatively short, primarily designed to guide the refrigerator in making minor angle adjustments, preparing for subsequent reversing actions. The refrigerator then continues moving, contacting the second reversing roller 312. The second reversing roller 312 is longer than the first reversing roller 311, further guiding the refrigerator in angle adjustments and gradually shifting the refrigerator's center of gravity to the reversing roller assembly 310. Finally, the refrigerator fully contacts the reversing roller assembly 310, which is the longest set of rollers, sufficient to support the refrigerator's overall weight and smoothly complete the reversing action. This incremental roller length design ensures the stability and continuity of the refrigerator during the reversing process, avoiding shocks and instability caused by sudden angle changes or weight transfers. Simultaneously, this design improves reversing efficiency, enabling the refrigerator to quickly and accurately complete the reversing process and proceed to the next step.

[0042] The second conveying section 220 is configured identically to the first conveying structure; and the first conveying section 210, the second conveying section 220, and the reversing section 300 are each driven by a drive motor; and the drive motors of the first conveying section 210, the second conveying section 220, and the reversing section 300 start or stop simultaneously. This configuration ensures a high degree of coordination and synchronization of the entire conveying system during operation. The first conveying section 210 and the second conveying section 220 employ the same conveying structure, meaning they have similar conveying capabilities and characteristics, enabling seamless connection and transfer of refrigerators, reducing potential conveying interruptions or malfunctions due to structural differences. Simultaneously, the unified drive of the first conveying section 210, the second conveying section 220, and the reversing section 300 by drive motors, and their simultaneous start or stop, further enhances the overall integrity and stability of the system. This design not only improves conveying efficiency but also simplifies the operation process, reduces maintenance costs, and makes the entire conveying system more reliable and efficient.

[0043] Limiting frames are also installed on both sides of the frame 100. Because the rotating rollers rotate at high speeds during transport, vibration or tipping may occur. Therefore, the limiting frames effectively position and secure the refrigerators, preventing them from tipping over due to vibration or excessive speed during transport. The use of limiting frames not only improves the safety and stability of the transport process but also further ensures the integrity of the refrigerators during transport, avoiding quality problems that may result from tipping or collisions. This meticulous design reflects strict control over every detail of the transport process, ensuring the efficient and reliable operation of the entire transport system.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
