Description

Technical Field

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

[0002] In the later stages of refrigerator manufacturing, to prevent damage to the bottom structure during storage and transportation, the refrigerator must be assembled and secured to its protective base. This process is a crucial step in ensuring the quality of the refrigerator before it leaves the factory. Currently, the industry generally relies on segmented, semi-automated or manually assisted operation modes for the assembly of refrigerators and protective bases, and a complete automated assembly system has not yet been formed. In particular, there are significant technical shortcomings in the connection links of conveying, clamping, flipping, and docking assembly.

[0003] Specifically, existing assembly processes are typically divided into several independent steps:

[0004] First, the refrigerator is transported to the designated workstation via a simple conveyor roller. During this process, there is a lack of precise positioning and connection mechanisms, requiring manual assistance to adjust the refrigerator's position to ensure that subsequent clamping operations can be carried out. Subsequently, the refrigerator is fixed with the help of a small clamping device. These devices are mostly fixed structures and cannot achieve multi-angle flipping. If it is necessary to flip the refrigerator to an assembly angle that matches the protective base, the flipping action must be completed manually with the help of a lifting tool or auxiliary tool, which is not only cumbersome but also poses a safety hazard. At the same time, the protective base needs to be transported through another set of independent conveying equipment. After the protective base is transported to the assembly workstation, the relative positions of the refrigerator and the protective base need to be adjusted manually to ensure that they are aligned before fixed assembly.

[0005] In the aforementioned process, due to the lack of a continuous automated conveying and clamping mechanism, the conveying, clamping, flipping, and docking of the refrigerator with the protective base cannot be integrated into a unified operation. Each process requires manual intervention for connection, resulting in significant breaks in the assembly process. On the one hand, manual connection not only prolongs the assembly cycle and reduces overall production efficiency, but also easily leads to insufficient alignment accuracy between the refrigerator and the protective base due to human error, affecting the stability of assembly quality. On the other hand, the segmented operation mode prevents the production line from operating continuously. During process switching, problems such as equipment idleness and personnel waiting can easily occur, resulting in wasted production resources and further exacerbating the problem of poor production continuity, making it difficult to meet the demands of large-scale, high-efficiency refrigerator mass production. Utility Model Content

[0006] In view of this, the present invention provides an assembly device for a refrigerator and a protective base, which solves the technical problem in the prior art that the lack of a continuous automated conveying and clamping mechanism makes it impossible to realize the integrated operation of refrigerator conveying, clamping and flipping and docking with the protective base, resulting in a broken assembly process and poor production continuity.

[0037] Example 1

[0038] Please see Figure 1 This utility model embodiment provides an assembly device for a refrigerator and a protective base. In the later stages of refrigerator production, the bottom structure of the refrigerator 110 needs to be assembled and fixed with the protective base 120 to protect it. This process is crucial to the quality of the refrigerator 110 leaving the factory. However, at present, this assembly operation in the industry generally relies on segmented semi-automatic or manual assistance, and a complete automated assembly system has not yet been formed. In particular, there are obvious technical shortcomings in the connection links of conveying, clamping, flipping and docking assembly. The existing process is often divided into multiple independent steps: when the refrigerator 110 is sent to the work station by a simple conveyor roller, the position needs to be adjusted manually. After the refrigerator 110 is fixed with a fixed small clamping device, it still needs to be manually flipped to a suitable angle with the assistance of a hoist. The protective base 120 is conveyed by another independent device and needs to be manually adjusted to align with the refrigerator 110. Due to the lack of a continuous automated conveying and clamping mechanism, the various operations cannot be integrated and linked, and manual intervention is required to connect them, resulting in a broken assembly process. This not only prolongs the assembly cycle, reduces production efficiency, and affects the stability of assembly quality due to human error, but also makes it difficult for the production line to operate continuously, resulting in resource waste and making it difficult to meet the needs of large-scale and efficient mass production.

[0039] Please see Figure 1 This embodiment provides an assembly device for a refrigerator 110 and a protective base 120. The assembly device includes a rotating clamping mechanism 200 that clamps the refrigerator 110 and places it on the protective base 120. The rotating clamping mechanism 200 includes a pair of rotating bases 210 and a rotating seat 220 that rotates based on the pair of rotating bases 210. The rotating seat 220 is provided with a track plate 230 and a first clamping part 241 and a second clamping part 242 disposed on the track plate 230. The first clamping part 241 and the second clamping part 242 are connected by a clamping cylinder 243. A clamping space for the refrigerator 110 is provided between the first clamping part 241 and the second clamping part 242. The first clamping part 241 is fixedly disposed on the track plate 230. The second clamping part 242 can move towards or away from the first clamping part 241 through the clamping cylinder 243 and based on the track plate 230 to achieve clamping or releasing action of the refrigerator 110.

[0040] Further, please see Figure 1 and Figure 2 A first conveying mechanism 300 for conveying the refrigerator 110 to a preset position is provided on one side of the rotating clamping mechanism 200.

[0041] During assembly, the refrigerator 110 to be assembled is placed horizontally with the door facing upwards and the bottom facing the rotating clamping mechanism 200. It is then conveyed on the first conveying mechanism 300, which uses the rotation of the transmission roller 311 to stably transport the refrigerator 110 to the preset clamping position. If no conveying mechanism is provided, the refrigerator 110 is manually placed in the preset clamping position according to the preset shape. At this time, the bottom of the refrigerator 110 and the clamping space of the rotating clamping mechanism 200 are in a suitable alignment state. When the refrigerator 110 arrives... After the preset position is reached, the clamping mechanism 200 is rotated to start the operation. The clamping cylinder 243 on its track plate 230 first extends to drive the second clamping part 242, causing the second clamping part 242 to move along the track plate 230 toward the fixedly set first clamping part 241, until the first clamping part 241 and the second clamping part 242 respectively fit against the outer walls of the two transverse sides of the refrigerator 110, forming a stable clamping space for the refrigerator 110. The clamping space is precisely matched with the transverse dimension of the refrigerator 110, avoiding displacement or damage to the refrigerator 110 during the clamping process. After clamping is completed, The rotating base 220, based on a pair of rotating bases 210, begins to rotate around a horizontal axis, causing the clamped refrigerator 110 to flip synchronously. During the flipping process, because the first clamping part 241 and the second clamping part 242 maintain a stable clamping force, the refrigerator 110 will not shake or fall off, until the rotating base 220 flips the refrigerator 110 to a preset angle, usually 90° or an angle that matches the placement posture of the protective base 120, ensuring that the bottom of the refrigerator 110 is aligned with the preset position of the protective base 120 below. When the refrigerator 110 is flipped to... After the target angle is aligned with the protective base 120, the clamping cylinder 243 retracts to drive the second clamping part 242 to move away from the first clamping part 241 along the track plate 230, releasing the clamping force on the refrigerator 110, allowing the refrigerator 110 to fall smoothly and be placed on the preset protective base 120, thus completing the assembly operation of the refrigerator 110 and the protective base 120. After the assembly is completed, the rotating seat 220 rotates in the opposite direction to reset, waiting to receive the refrigerator 110 conveyed by the first conveying mechanism 300 for the next time, and enters the next assembly cycle.

[0042] Further, please see Figure 1 and Figure 3On the clamping surfaces of the first clamping part 241 and the second clamping part 242 that are used to contact the outer wall of the refrigerator 110, a high-friction coefficient anti-slip layer is attached. The anti-slip layer is a rubber anti-slip pad with anti-slip texture. The anti-slip layer is tightly connected to the clamping surface by adhesive or bolt fixation. The rough texture of its surface can greatly increase the friction between the clamping surface and the outer wall of the refrigerator 110. When the clamping cylinder 243 drives the second clamping part 242 to move toward the first clamping part 241 and fit against the refrigerator 110, the anti-slip layer can effectively prevent the refrigerator 110 from sliding relative to the outside due to external force in the clamping state. This not only ensures the clamping stability, but also buffers the clamping force through the flexible anti-slip layer, preventing the hard clamping surface from directly contacting the outer wall of the refrigerator 110 and causing scratches or dents, thus protecting the appearance of the refrigerator 110.

[0043] Meanwhile, pressure sensors or contact sensors are embedded at the edges of the clamping surfaces of the first clamping part 241 and the second clamping part 242, respectively. These sensors are electrically connected to the control system of the assembly equipment. When the second clamping part 242 moves toward the first clamping part 241 and gradually clamps the refrigerator 110, as the clamping force increases, the pressure sensor will detect the contact pressure between the clamping surface and the outer wall of the refrigerator 110 in real time and transmit the pressure signal to the control system. When the detected pressure value reaches the preset threshold, the control system determines that the refrigerator 110 has been clamped in place and then sends a stop drive signal to the clamping cylinder 243 to avoid damage to the refrigerator 110 due to excessive clamping force. If the sensor does not detect the preset pressure value, the control system will issue an alarm signal to remind the staff to check the problem, effectively preventing the refrigerator 110 from falling off during the flipping or moving process due to improper clamping, further improving the safety and reliability of the assembly operation, and ensuring the accuracy of subsequent flipping, alignment, and lowering assembly processes.

[0044] Further, please see Figure 2 The first conveying mechanism 300 includes a frame 310 and a plurality of transmission rollers 311 spaced apart on the frame 310, and the transmission rollers 311 are connected in transmission between each other; the transmission rollers 311 at one end of the frame 310 are driven by a motor 320.

[0045] Furthermore, in actual use, we noticed a phenomenon that refrigerators 110 of different sizes often have a certain distance difference from the rotating clamping mechanism 200 when they are transported to the clamping position by the first conveying mechanism 300.

[0046] This is because the positions of the first conveying mechanism 300 and the rotating clamping mechanism 200 in the equipment layout are fixed and cannot be flexibly adjusted according to the specific size of the refrigerator 110.

[0047] To solve this problem and ensure that the refrigerator 110 can accurately reach the position suitable for the rotating clamping mechanism 200 to operate, an auxiliary mechanism needs to be introduced to accomplish this task.

[0048] Therefore, please see Figure 1 and Figure 4 In this embodiment, a dedicated lifting and conveying mechanism 500 is added between the first conveying mechanism 300 and the rotating clamping mechanism 200. The main function of this lifting and conveying mechanism 500 is to lift the refrigerator 110 from a preset position and then precisely convey it to the clamping position, thereby compensating for the positional deviation caused by the size difference of the refrigerator 110 and ensuring that the entire transportation and clamping process is more efficient and accurate.

[0049] The lifting and conveying mechanism 500 includes a lifting part 510 and a conveying part 520 that can perform lifting operations based on the lifting part 510; the conveying part 520 is disposed on the lifting part 510 via a pair of slide rails and a slider and can perform lifting operations through the cooperation of the slider and the slide rails.

[0050] The lifting unit 510 is configured to be driven by a lead screw, a pneumatic cylinder, or a hydraulic cylinder.

[0051] In use, when the refrigerator 110 to be assembled is transported laterally to the preset position, i.e., when the first conveying mechanism 300 is close to the end position of the rotating clamping mechanism 200, the lifting conveying mechanism 500 starts operation. First, based on the height difference between the bottom of the refrigerator 110 and the clamping space of the rotating clamping mechanism 200, the lifting part 510 drives the conveying part 520 to rise and fall along the cooperation structure of the slide rail and the slider: if a cylinder is used for driving, the cylinder piston rod extends to push the conveying part 520 to rise along the slide rail; if a screw is used for driving, the motor 320 drives the screw to rotate, and through the screw nut, the conveying part 520 is driven to rise and fall smoothly until the conveying part 520 reaches its maximum height. The feeder is placed against the bottom of the refrigerator 110, and the refrigerator 110 is raised to a position that matches the height of the clamping space of the rotating clamping mechanism 200. Then, the conveying unit 520 is started, and the raised refrigerator 110 is horizontally conveyed towards the rotating clamping mechanism 200, and accurately pushed to a better clamping position of the rotating clamping mechanism 200. After the refrigerator 110 reaches this position, the conveying unit 520 stops operating, and the lifting unit 510 drives the conveying unit 520 to descend and reset, returning to the initial height to wait for the next conveying operation. At this time, the rotating clamping mechanism 200 starts the clamping cylinder 243 again, driving the second clamping part 242 to move towards the first clamping part 241, completing the stable clamping of the refrigerator 110.

[0052] The core advantage of this setup is that it effectively solves the problem of distance / height differences between refrigerators 110 of different sizes and the fixed-position rotating clamping mechanism 200. Through the height adjustment of the lifting part 510 and the horizontal conveying of the conveying part 520, it can adapt to refrigerators 110 of various heights and widths, breaking the limitations of the original fixed mechanism on the size of the refrigerator 110 and improving the versatility of the equipment. Compared with directly relying on the first conveying mechanism 300 to convey to the clamping position, the lifting conveying mechanism 500 can accurately push the refrigerator 110 to the clamping center area, avoiding uneven force or incomplete clamping of the first clamping part 241 and the second clamping part 242 due to the offset of the refrigerator 110, significantly improving the clamping stability of the rotating clamping mechanism 200 and the subsequent flipping alignment accuracy. Moreover, no manual intervention is required in the entire lifting and conveying process, and it is fully automated with the first conveying mechanism 300 and the rotating clamping mechanism 200. This avoids the tedious operation of manually adjusting the position of the refrigerator 110 and eliminates the errors that may be caused by manual adjustment, further ensuring the continuity and automation of the assembly process, and indirectly improving the overall production efficiency.

[0053] Furthermore, a second conveying mechanism 400 for conveying the assembled refrigerator 110 and protective base 120 is provided on one side of the rotating clamping mechanism 200; the second conveying mechanism 400 has the same structure as the first conveying mechanism 300.

[0054] Further, please see Figure 5 and Figure 6 The second conveying mechanism 400 is further provided with a feeding mechanism 600 for feeding the protective base 120 on the side away from the rotating clamping mechanism 200; the feeding mechanism 600 includes a feeding part 610 and a feeding part 630; the feeding part 610 includes a pair of limiting plates 611 and a conveying roller 612 disposed between the pair of limiting plates 611; the feeding part 630 includes a cylinder seat 631 and a pushing cylinder 632 disposed on the cylinder seat 631, and a pair of guide rods 633 that can be extended and retracted based on the cylinder seat 631 are provided on both sides of the cylinder seat 631, and a pushing plate 634 is provided at the end of the pair of guide rods 633, and an isolation plate 635 is provided at the top of the pushing plate 634.

[0055] Furthermore, the feeding section 610 is also provided with a limiting frame, in which a plurality of protective bases 120 are stacked. The feeding section 630 is used to push the protective bases 120 in the limiting frame, thereby moving the protective bases 120 from the feeding section 610 to the second conveying mechanism 400 for assembly with the refrigerator 110.

[0056] During assembly, for the feeding stage of the protective base 120, workers pre-stack several protective bases 120 into the limiting frame of the feeding section 610 of the feeding mechanism 600. The limiting frame can circumferentially limit the stacked protective bases 120 to prevent them from tipping over or shifting. When it is necessary to feed the protective base 120 to the second conveying mechanism 400, the feeding section 630 starts operation; the push cylinder 632 on the cylinder seat 631 extends, driving the guide rods 633 on both sides to extend synchronously. The push plate 634 at the end of the guide rod 633 moves towards the limiting frame. The isolation plate 635 on the top of the push plate 634 can contact the upper protective base 120 during the pushing process. 0 forms an isolation, applying a thrust only to the single protective base 120 at the bottom of the limit frame, ensuring that only one protective base 120 is pushed at a time; under the continuous thrust of the push cylinder 632, the bottom protective base 120 disengages from the limit frame and enters the conveyor roller 612 between a pair of limit plates 611 in the feeding section 610. The limit plates 611 can limit the lateral displacement of the protective base 120 during the conveying process. The conveyor roller 612 starts and accurately conveys the protective base 120 to the designated assembly position of the second conveying mechanism 400. Then, the push cylinder 632 of the feeding section 630 retracts, driving the push plate 634 and guide rod 633 to reset, waiting for the next pushing operation.

[0057] Once the rotating clamping mechanism 200 completes the flipping of the refrigerator 110 and the protective base 120, which has been pre-transported to the assembly position on the second conveying mechanism 400, is stably placed on the refrigerator 110, the initial assembly of the refrigerator 110 and the protective base 120 is completed. At this time, the second conveying mechanism 400 is activated. Since the second conveying mechanism 400 has the same structure as the first conveying mechanism 300, it also includes a frame 310, spaced transmission rollers 311, and a drive motor 320. The transmission rollers 311 rotate under the drive of the motor 320, which drives the assembled refrigerator 110 and the protective base 120 to be transported away from the rotating clamping mechanism 200. This can not only avoid the accumulation of finished products at the assembly station, but also transport the finished products to the subsequent fixing, testing, or packaging processes, realizing the connection of the entire process from feeding the protective base 120 and assembling it with the refrigerator 110 to the output of the finished product, and further improving the automated assembly system.

[0058] 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. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
