Description

Technical Field

[0001] This utility model belongs to the field of conveyor line technology, specifically relating to a vertical return assembly line. Background Technology

[0002] With the increasing demand for efficient circular transmission in automated production, transmission equipment has been upgraded from traditional linear conveyor belts to circular transmission systems, which are widely used in precision manufacturing, heavy industry and other fields.

[0003] Existing circulating conveyor systems generally use horizontal circulating equipment, which requires a large amount of floor space. In scenarios where the workshop has sufficient height but a compact floor plan, this results in a waste of floor space.

[0004] Modern factories often use multi-level production lines, such as upper-level assembly and lower-level testing. Existing horizontal circulation equipment requires additional vertical transmission equipment for cross-level transmission, which not only increases equipment costs but also causes jams at the connection points, making it impossible to meet the needs of continuous circulation transmission.

[0005] Traditional vertical conveying equipment can only achieve single-point vertical conveying and cannot form a vertical cycle. Furthermore, materials are prone to shifting due to gravity during vertical conveying, which cannot meet the vertical cycle requirements of precision materials. Utility Model Content

[0034] 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. The described embodiments are some, but not all, of the embodiments of this utility model.

[0035] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0036] To address the problems of low space utilization and bottlenecks at the connection between the additionally configured vertical transmission equipment and the horizontal circulation equipment in the prior art, which prevent the continuous circulation transmission requirement from being met, this utility model provides a vertical return assembly line.

[0037] like Figure 1-3 As shown, this embodiment discloses a vertical return assembly line, including: a product conveying mechanism 10, a fixture return mechanism 30, a first vertical conveying mechanism 40, and a second vertical conveying mechanism 50.

[0038] The product conveying mechanism 10 is used to transport materials 100 in the horizontal direction.

[0039] Specifically, such as Figure 4 As shown, the product conveying mechanism 10 includes a first frame 11 and a first track assembly 12 disposed on the first frame 11 along the length direction of the first frame 11. A plurality of fixture assemblies 20 are provided on the first track assembly 12 and are slidably connected to the first track assembly 12.

[0040] In this embodiment, it should be clarified that the material 100 to be transported is placed on the fixture assembly 20. The material 100 is loaded at the first end of the product conveying mechanism 10 and unloaded at the second end of the product conveying mechanism 10. When the material 100 is transported along the first track assembly 12 through the fixture assembly 20, it is driven by an external drive mechanism to drive the material 100 from the loading station to the unloading station along the first track assembly 12 through the fixture assembly 20.

[0041] The fixture return mechanism 30 is mounted on the first frame 11 and is located below the first track assembly 12 along the conveying direction of the product conveying mechanism 10, so as to realize the horizontal return of the empty fixture assembly 20.

[0042] The first vertical conveying mechanism 40 is disposed at the input end of the first frame 11 along the conveying direction of the product conveying mechanism 10. It can move up and down between the product conveying mechanism 10 and the fixture return mechanism 30 to alternately connect with the product conveying mechanism 10 and the fixture return mechanism 30, and move the fixture assembly 20 output by the fixture return mechanism 30 upward to the product conveying mechanism 10.

[0043] The second vertical conveying mechanism 50 is disposed at the output end of the first frame 11 along the conveying direction of the product conveying mechanism 10. It can move up and down between the product conveying mechanism 10 and the fixture return mechanism 30 to alternately connect with the product conveying mechanism 10 and the fixture return mechanism 30, and move the fixture assembly 20 output by the product conveying mechanism 10 downward to the fixture return mechanism 30.

[0044] That is, in this embodiment, the first vertical conveying mechanism 40 and the second vertical conveying mechanism 50 are respectively located at both ends of the first frame 11, and can be lifted and connected to the product conveying mechanism 10 and the fixture return mechanism 30 to complete the vertical circulation of the fixture assembly 20.

[0045] Therefore, by placing the fixture return mechanism 30 directly below the product conveying mechanism 10, this embodiment reduces the overall space occupancy rate, making the assembly line suitable for scenarios with sufficient height but compact floor plan, such as cleanrooms for electronic components and multi-level automated warehouses. The first vertical conveying mechanism 40 and the second vertical conveying mechanism 50 are respectively located at both ends of the first frame 11, and can be lifted and connected to the product conveying mechanism 10 and the fixture return mechanism 30 to complete the vertical circulation of the fixture assembly 20. No additional independent vertical transmission equipment is required, which improves the equipment integration and connection accuracy and reduces the enterprise's equipment costs.

[0046] In this embodiment, the first vertical conveying mechanism 40 transfers the empty fixture assembly 20 returned by the lower fixture return mechanism 30 to the upper product conveying mechanism 10, and the second vertical conveying mechanism 50 transfers the empty fixture assembly 20 output by the upper product conveying mechanism 10 to the lower fixture return mechanism 30, forming a closed loop of product transfer and vertical return of empty fixture assembly 20, which improves the transfer efficiency and connection accuracy of the assembly line and eliminates positioning deviations caused by manual intervention.

[0047] In addition, the product conveying mechanism 10, the fixture return mechanism 30, the first vertical conveying mechanism 40 and the second vertical conveying mechanism 50 are controlled independently, which can adjust their respective transmission speeds according to actual needs and avoid material jamming and waiting.

[0048] This embodiment is a preferred embodiment, and the specific structure of the fixture return mechanism 30 has been optimized.

[0049] In this implementation, such as Figure 10-11 As shown, the fixture return mechanism 30 includes a second track assembly 31, a first conveying assembly 32 disposed on one side of the second track assembly 31, and a first drive motor 33 for driving the first conveying assembly 32 to move. The two ends of the first conveying assembly 32 extend to the first vertical conveying mechanism 40 and the second vertical conveying mechanism 50, respectively. The second track assembly 31 has the same structure as the first track assembly 12 and is located directly below the first track assembly 12.

[0050] Specifically, in this embodiment, the first drive motor 33 is respectively located at the first vertical conveying mechanism 40 and the second vertical conveying mechanism 50. The output end of the first drive motor 33 is provided with a drive wheel. The first conveying component 32 is wound around the two drive wheels and moves under the drive of the first drive motor 33.

[0051] In addition, the fixture return mechanism 30 also includes a number of first limiting guide plates. The number of first limiting guide plates are arranged on one side of the second track assembly 31 along the conveying direction of the first conveying assembly 32. The first conveying assembly 32 moves along the first limiting guide plates to limit the first conveying assembly 32.

[0052] In this embodiment, the first conveying component 32 may be a conveying belt or a conveying chain, and the drive wheel connected to the output end of the first drive motor 33 is matched with the conveying belt or the conveying chain.

[0053] Given that the first conveying component 32 of the jig return mechanism 30 in this embodiment is used to drive the empty jig assembly 20 to achieve horizontal return, the structure of the jig assembly 20 needs to cooperate with the first conveying component 32 and the second track assembly 31.

[0054] In this embodiment, the empty fixture assembly 20 slides along the second track assembly 31, optimizing its transmission offset to maintain consistent positioning accuracy with the product conveying mechanism 10, thus meeting the requirements for precision material transmission; and the first conveying assembly 32 is seamlessly connected to the first vertical conveying mechanism 40 and the second vertical conveying mechanism 50 without any gaps, optimizing its jamming rate.

[0055] The first drive motor 33 independently controls the speed of the first conveying component 32, and can dynamically adapt to the rhythm of the product conveying mechanism 10, avoiding the accumulation of empty fixture components 20 and improving overall production efficiency.

[0056] In this embodiment, as Figure 12-13 As shown, the jig assembly 20 includes a first jig 21 and a second jig 22 with identical structures, and the first jig 21 and the second jig 22 are connected by a connecting rod 23.

[0057] Specifically, the first fixture 21 has snap-fit ​​grooves at both ends, and the connecting rod 23 has snap-fit ​​parts at both ends. The connecting rod 23 is embedded in the snap-fit ​​grooves through the snap-fit ​​parts, thereby connecting the first fixture 21 and the second fixture 22 into one unit, so that the fixture assembly 20 can transport large materials 100.

[0058] In this embodiment, the first fixture 21 includes a connecting plate 211 and two sets of rollers 212 disposed on the connecting plate 211. The two sets of rollers 212 are disposed on both sides of the first track assembly 12 and are slidably connected to the first track assembly 12. A limiting tooth 213 is provided on one side of the connecting plate 211, which can engage with the first conveying assembly 32.

[0059] Specifically, when the first conveying component 32 is a conveyor belt, a limiting slot that matches the limiting tooth 213 can be provided on the conveyor belt; when the first conveying component 32 is a conveyor chain, the limiting tooth 213 matches the slot of the conveyor chain.

[0060] When the second vertical conveying mechanism 50 moves the empty fixture assembly 20 output from the upper product conveying mechanism 10 downward, the limiting teeth 213 of the fixture assembly 20 directly engage with the first conveying assembly 32, and under the drive of the first drive motor 33, it moves along the second track assembly 31 to achieve return flow.

[0061] This embodiment is a preferred embodiment, and the specific structures of the first vertical conveying mechanism 40 and the second vertical conveying mechanism 50 have been optimized.

[0062] In this embodiment, as Figure 5-6 , Figure 8-9 As shown, the first vertical conveying mechanism 40 includes a first mounting frame 41, a first mounting platform 42, a first lifting component 43, and a first drive mechanism 44. The first lifting component 43 is mounted on the first mounting frame 41, and the output end of the first lifting component 43 is connected to the first mounting platform 42 to drive the first mounting platform 42 to move up and down along the first mounting frame 41. A third track component 45 with the same structure as the first track component 12 is provided on the first mounting platform 42. The first drive mechanism 44 is located on one side of the first mounting platform 42. When the third track component 45 is connected to the first track component 12, the first drive mechanism 44 conveys the fixture component 20 located on the third track component 45 to the first track component 12.

[0063] Preferably, the first drive mechanism 44 includes a second transmission component 441 and a second drive motor 442 that drives the second transmission component 441 to move. A first push block 443 is fixedly connected to the second transmission component 441. The first push block 443 can abut against the jig component 20 to push the jig component 20 located on the third track component 45 onto the first track component 12 during the transmission process of the second transmission component 441.

[0064] In this embodiment, the second conveying component 441 does not directly contact the fixture component 20. Instead, it abuts against the fixture component 20 through the first pusher 443 provided thereon, thereby transferring the fixture component 20 during the transmission process.

[0065] In addition, the first vertical conveying mechanism 40 also includes a first positioning member 46, which is disposed on the first mounting platform 42 and located outside the third track assembly 45. The first positioning member 46 is used to position the jig assembly 20 located on the third track assembly 45.

[0066] That is, when the jig assembly 20 is transferred to the third track assembly 45 by the first drive mechanism 44 and positioned by the first positioning member 46, it is transferred in the vertical direction by the first lifting assembly 43.

[0067] In this embodiment, the second conveying component 441 may be a conveying belt or a conveying chain, and the drive wheel connected to the output end of the second drive motor 442 is matched with the conveying belt or the conveying chain.

[0068] In this embodiment, the second vertical conveying mechanism 50 includes a second mounting frame, a second mounting platform, a second lifting assembly, and a second driving mechanism. The second lifting assembly is mounted on the second mounting frame, and the output end of the second lifting assembly is connected to the second mounting platform to drive the second mounting platform to move up and down along the second mounting frame. A fourth track assembly with the same structure as the first track assembly 12 is provided on the second mounting platform. The second driving mechanism is located on one side of the second mounting platform. When the fourth track assembly is connected to the first track assembly 12, the second driving mechanism conveys the jig assembly 20 located on the fourth track assembly to the first track assembly 12.

[0069] Preferably, the second drive mechanism includes a third transmission component and a third drive motor for driving the third transmission component to move. A second push block is fixedly connected to the third transmission component. The second push block can abut against the jig component 20 so as to transport the jig component 20 output along the first track component 12 to the fourth track component during the transmission process of the third transmission component.

[0070] The second vertical conveying mechanism 50 also includes a second positioning member, which is disposed on the second mounting platform and located outside the fourth track assembly. The second positioning member is used to position the jig assembly 20 located on the fourth track assembly.

[0071] In this embodiment, since the second vertical conveying mechanism 50 has the same structure as the first vertical conveying mechanism 40, the description of the second vertical conveying mechanism 50 is omitted.

[0072] This embodiment is a preferred embodiment, and the vertical return assembly line also includes a loading mechanism 60 and a unloading mechanism 70.

[0073] The feeding mechanism 60 is located between the product conveying mechanism 10 and the first vertical conveying mechanism 40. The first driving mechanism 44 extends to the opposite end of the feeding mechanism 60 to the product conveying mechanism 10. The fixture assembly 20 located on the third track assembly 45 is driven to the feeding mechanism 60 by the first driving mechanism 44.

[0074] The unloading mechanism 70 is disposed between the product conveying mechanism 10 and the second vertical conveying mechanism 50. The second drive mechanism extends to the opposite end of the unloading mechanism 70 to the product conveying mechanism 10. The fixture assembly 20 located on the unloading mechanism 70 is driven to the fourth track assembly by the second drive mechanism.

[0075] The fixture return mechanism 30 passes sequentially from the location of the first vertical conveying mechanism 40 through the loading mechanism 60, the product conveying mechanism 10, and the unloading mechanism 70 to the location of the second vertical conveying mechanism 50.

[0076] In this embodiment, as Figure 7 As shown, the feeding mechanism 60 includes a second frame 61, and the first track assembly 12 extends to the opposite end of the second frame 61 to the first vertical conveying mechanism 40; a plurality of second limiting guide plates 62 are provided on the second frame 61, and the plurality of second limiting guide plates 62 are arranged on one side of the first track assembly 12 along the length direction of the first track assembly 12, and the first driving mechanism 44 moves along the second limiting guide plates 62.

[0077] Given that the first drive mechanism 44 includes a second conveying component 441 and a second drive motor 442 for driving the second conveying component 441, and that the first drive mechanism 44 extends to the end of the loading mechanism 60 opposite to the product conveying mechanism 10, the second conveying component 441 extends from the location of the first vertical conveying mechanism 40 to the end of the loading mechanism 60 opposite to the first vertical conveying mechanism 40. The second conveying component 441 moves along the second limiting guide plate 62 under the drive of the first drive mechanism 44.

[0078] In this embodiment, two second drive motors 442 can be configured, and the two second drive motors 442 are respectively mounted on the first mounting bracket 41 and the second frame 61.

[0079] In some alternative implementations, the second drive motor 442 can be configured as one, with the second drive motor 442 mounted on the first mounting bracket 41, and a driven wheel 444 cooperating with the drive wheel of the second drive motor 442 disposed on the second frame 61.

[0080] In addition, the feeding mechanism 60 also includes a third positioning element 63, which is disposed on the second frame 61 and located outside the first track assembly 12. The third positioning element 63 is used to position the fixture assembly 20 located on the feeding mechanism 60. When the fixture assembly 20 is driven onto the feeding mechanism 60 by the first drive mechanism 44, it is positioned by the third positioning element 63 to ensure the feeding accuracy of the material 100.

[0081] The unloading mechanism 70 includes a third frame, and the first track assembly 12 extends to the end of the third frame opposite to the second vertical conveying mechanism 50. A plurality of third limiting guide plates are provided on the third frame, and the plurality of third limiting guide plates are arranged on one side of the first track assembly 12 along the length direction of the first track assembly 12. The second drive mechanism moves along the third limiting guide plates.

[0082] The unloading mechanism 70 also includes a fourth positioning element, which is disposed on the third frame and located outside the first track assembly 12. The fourth positioning element is used to position the fixture assembly 20 located on the unloading mechanism 70.

[0083] In this embodiment, since the unloading mechanism 70 and the loading mechanism 60 have the same structure, the description of the unloading mechanism 70 is omitted.

[0084] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0085] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0086] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
