Description

Technical Field

[0001] This utility model relates to the field of massage chair assembly technology, and more specifically to a massage chair assembly line. Background Technology

[0002] The massage chair assembly line integrates the necessary processes for massage chair production and assembly, such as manual assembly stations for various components, finished product inspection stations, and pallet recycling stations, through a conveyor belt. Currently, the existing massage chair assembly lines still have significant shortcomings.

[0003] On the one hand, existing assembly lines often use a fixed-cycle, single-direction conveyor belt design. When the operation time of a certain workstation is extended due to differences in process complexity, temporary equipment failure, or personnel operation delays, the subsequent massage chairs cannot be efficiently transferred and are very likely to accumulate at the front end of the bottleneck workstation, disrupting the overall production rhythm.

[0004] On the other hand, the layout of the final assembly line is not perfect, which makes the connection between various processes on the production line not smooth. For example, when a massage chair fails the test, it needs to be moved outside the final assembly line for repair. This repeated moving not only wastes a lot of manpower, but also greatly slows down the overall production efficiency. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0028] A massage chair assembly line, such as Figures 1 to 4 As shown, the system includes a conveyor belt with several pallets 13 for placing products. Along the conveying direction, the conveyor belt sequentially includes a first assembly section 1, a first handling section 3, a second assembly section 2, a finished product testing section 4, and a pallet 13 recovery section 5. The two ends of the pallet 13 recovery section 5 are connected to the finished product testing section 4 and the first assembly section 1, respectively. Massage chairs are placed on the pallets 13 and move along the conveyor belt through each workstation. After passing the product testing section, they are separated from the pallets 13 and stacked in the pallet 13 recovery section 5, awaiting replenishment back to the first assembly section 1.

[0029] The first transport section 3 is connected to a buffer section 6, which can be used to buffer some products when products are piled up in front. The product testing section is connected to a maintenance section, with its two ends connected to the input and output ends of the finished product testing section 4, respectively. Products that fail the test can be moved directly to the maintenance section, and after maintenance, they are returned directly to the input end of the product testing section for further testing.

[0030] The first assembly section 1 and the second assembly section 2 have opposite conveying directions. The output end of the first assembly section 1 and the input end of the second assembly section 2 are connected by the first transport section 3, which is perpendicular to the first assembly section 1. The buffer section 6 is arranged between the first assembly section 1 and the second assembly section 2 and is connected to the first transport section 3. The buffer section 6 can convey in both directions. Since the processes in the finished product testing section 4 take a long time, the products tend to accumulate in the second assembly section 2. Therefore, some of the subsequent products can be moved to the buffer section 6 to wait.

[0031] The first transport section 3 includes a transport conveyor belt. Lifting and transporting modules 302 are installed at both ends of the transport conveyor belt and at its connection with the buffer section 6. The lifting and transporting modules 302 are used to separate the pallet 13 from the conveyor belt and feed it into the transport conveyor belt. The lifting and transporting module 302 includes a separation conveyor belt 3021. A lifting cylinder 3022 is connected to the bottom of the separation conveyor belt 3021. When the pallet 13 moves above the separation conveyor belt 3021, the lifting cylinder 3022 lifts the separation conveyor belt 3021, thereby separating the pallet 13 from the conveyor belt. When the separation conveyor belt 3021 is aligned with the transport conveyor belt, it feeds the pallet 13 into the transport conveyor belt. Similarly, when the transport conveyor belt transports the pallet 13 to the separation conveyor belt 3021 at the second assembly section 2, the lifting cylinder 3022 controls the separation conveyor belt 3021 to descend below the conveyor belt, causing the pallet 13 to return to the conveyor belt.

[0032] The buffer section 6 can transport in both directions. When the products in the buffer section 6 need to be output, the conveyor belt of the buffer section 6 rotates in the direction of rotation, and the buffered products are transported back to the first transport section 3 through the lifting and handling module 302, and then transported to the second assembly section 2.

[0033] In this embodiment, the conveyor line adopts the existing technology of double-speed chain conveyor line. The two ends of the pallet 13 are attached to the conveyor line to realize the drive. The pallet 13 is conveyed in sections according to the rhythm. A stopper is set at each section of the conveying distance. The workers manually assemble the massage chair along the conveyor line in stages.

[0034] In this embodiment, the finished product testing section 4 is a silent testing room set up on the conveyor line, where staff members manually test the finished products.

[0035] The feed end of the rework section 7 is connected to the discharge end of the finished product testing section 4 via the second conveying section 8, and the discharge end of the rework section 7 is connected to the feed end of the finished product testing section 4 via the third conveying section 9. When the product passes the test, it continues to be conveyed forward along the conveyor belt. When it fails the test, the product is separated from the conveyor belt by the second conveying section 8 and sent into the rework section 7.

[0036] The discharge end of the rework section 7 is connected to the first assembly section 1 by a fourth transport section 10. When too much material accumulates in the rework section 7 and cannot be repaired in time, or when minor repairs cannot be completed, the product can be transported to the outside through the fourth transport section 10 to facilitate the removal of the product by the staff.

[0037] The feeding end of the pallet 13 recycling section 5 is connected to the discharge end of the finished product testing section 4 via the fifth transport section 11, and the discharge end of the pallet 13 recycling section 5 is connected to the first assembly section 1 via the sixth transport section 12. After the qualified products are output from the finished product testing section 4, the staff removes the massage chair from the pallet 13, and the pallet 13 is then transported to the pallet 13 recycling section 5 via the fifth transport section 11. Empty pallets 13 stored in the pallet 13 recycling section 5 can also be transported to the first assembly section 1, and the entire assembly line forms a rectangular loop.

[0038] In this embodiment, the second transport section 8, the third transport section 9, the fourth transport section 10, the fifth transport section 11 and the sixth transport section 12 all refer to the first transport section 3, and their structural principles will not be repeated. They all include a transport conveyor belt and a lifting transport module 302.

[0039] The pallet 13 recycling section 5 includes a recycling conveyor belt 501. Several stacker cranes 502 are arranged on one side of the recycling conveyor belt 501. Lifting and transporting modules 302 are respectively arranged between the inlet of the recycling conveyor belt 501 and the inlet of the stacker cranes 502. One of the lifting and transporting modules 302 is connected to the input end of the first assembly section 1 through the sixth transport section 12. The recycling conveyor belt 501 can transport in both directions.

[0040] like Figures 5 to 7As shown, the stacker crane 502 includes a loading component and a lifting component. The lifting component includes a lifting drive 5021, two sets of lifting chains 5022, and several support members 5023. The lifting drive 5021 simultaneously drives the two sets of lifting chains 5022 to rotate. Each set of lifting chains 5022 includes at least two lifting chains 5022. Each set of lifting chains 5022 is provided with multiple support members 5023 at intervals. The support members 5023 of the two sets of lifting chains 5022 are respectively provided one-to-one. The loading component is connected to the lifting and transporting module 302. The loading component loads the pallet 13 onto the support members 5023. The pallet 13 is placed on the support members 5023 on both sides. As the support members 5023 rise and fall, the pallet 13 is driven to rise and fall.

[0041] The lifting assembly also includes a transmission rod 5024 and two rotating rods 5025. The rotating rods 5025 are engaged with the two ends of the transmission rod 5024. The lifting chain 5022 is sleeved on the rotating rods 5025. The lifting drive 5021 drives the transmission rod 5024 to rotate, and the transmission rod 5024 drives the rotating rods 5025 to rotate, thereby driving the lifting chain 5022 to rotate in the vertical direction.

[0042] The feeding assembly includes a feeding drive 5026 and a feeding chain 5027. The feeding chain 5027 and the support member 5023 are arranged parallel to each other. The feeding drive 5026 drives the feeding chain 5027 to rotate, thereby driving the pallet 13 into the support member 5023. In this embodiment, both the lifting drive 5021 and the feeding drive 5026 are motors, and the output shaft of the motor meshes with the transmission member through gears.

[0043] The working process of this utility model is as follows:

[0044] The pallet 13 moves along the conveyor line from the first assembly section 1. Workers manually assemble the massage chair components at each stage. After passing through the first assembly section 1 and the second assembly section 2, the massage chair is assembled. It then enters the finished product testing section 4 for inspection. Massage chairs that pass inspection are conveyed out and separated from the pallet 13 for unloading. The pallet 13 is then conveyed to the pallet 13 recycling section 5. Massage chairs that fail inspection are conveyed through the second handling section 8 to the rework section 7 for manual repair, and then transported back to the input end of the finished product testing section 4 via the third handling section 9 for re-inspection. When a large number of massage chairs accumulate in the second assembly section 2, subsequent massage chairs from the first assembly section 1 can be stored in the buffer section 6 and conveyed to the second assembly section 2 only after the process is complete.
