Description

Technical Field

[0001] This application relates to the technical field of transmission equipment, and in particular to a double-layer conveying mechanism. Background Technology

[0002] Conveying mechanisms are a common type of automated transport equipment widely used in various assembly lines. They can automatically transport products to various assembly stations while processing various products, so as to complete the corresponding processing steps and improve production efficiency.

[0003] In related technologies, there is a conveying mechanism for processing transformer cover plates, which includes several support plates for supporting the transformer cover plates, a conveyor belt for conveying the support plates, and a rotary motor for controlling the rotation of the conveyor belt. When processing the transformer cover plates, the cover plates are first transported to the middle position of the conveyor belt via the support plates, and then the cover plates are removed from the support plates for processing. The empty support plates are then conveyed to the end of the conveyor belt.

[0004] However, during the processing of the above-mentioned conveying mechanism, workers need to manually move the support plate from the end of the conveyor belt to the front of the conveyor belt so that the support plate can be recycled, which is time-consuming, labor-intensive and has low transportation efficiency. Utility Model Content

[0005] To improve the transportation efficiency of the conveying mechanism, this application provides a double-layer conveying mechanism.

[0006] The double-layer conveying mechanism provided in this application adopts the following technical solution:

[0007] A double-layer conveying mechanism includes a frame, a support plate movably mounted on the frame for carrying a transformer cover plate, an upper conveying assembly and a lower conveying assembly for horizontally conveying the support plate, and two sets of lifting assemblies for vertically conveying the support plate. The upper conveying assembly is located above the lower conveying assembly, and their conveying directions are opposite. The two sets of lifting assemblies are respectively located on the side of the upper and lower conveying assemblies away from each other. Each lifting assembly includes a lifting slide rail fixedly mounted on the frame, a pallet slidably mounted on the lifting slide rail, and a transmission power component mounted on the frame. The pallet carries the support plate, and the transmission power component controls the pallet to move up and down along the lifting slide rail. The pallet at the output end of the upper conveying assembly is provided with a return assembly for conveying the support plate to the lower conveying assembly, and the pallet at the output end of the lower conveying assembly is provided with a transmission assembly for conveying the support plate to the upper conveying assembly.

[0008] By adopting the above technical solution, when the support plate is transferred to the output end of the upper conveying component, the pallet will move to a position flush with the upper conveying component under the action of the transmission power component. Then, the support plate will be transferred to the pallet by the upper conveying component. Subsequently, the transmission power component will move the pallet downward to a position flush with the lower conveying component, and under the action of the return component, the support plate will be moved to the lower conveying component. The lower conveying component will then move the support plate to the output end, and the transmission power component will move the support plate to the input end of the upper conveying component. Then, under the action of the transmission component, the support plate will be moved to the upper conveying component to continue the next transfer. By returning the support plate from the output end of the upper conveying component to the input end in this way, compared with manual transfer, manpower is saved and the transportation efficiency of the conveying mechanism is improved.

[0009] Optionally, the power transmission component includes a drive shaft, a transmission gear rotatably mounted on the drive shaft, a lifting gear located above the transmission gear, a cylinder chain meshing with the transmission gear and the lifting gear, and a transmission cylinder for controlling the vertical movement of the drive shaft. One end of the cylinder chain is fixedly connected to the frame, and the other end passes around the transmission gear and the lifting gear in sequence before being fixedly connected to the pallet.

[0010] By adopting the above technical solution, when the power transmission component controls the pallet to move up and down, the transmission cylinder is connected to the pallet through the cylinder chain. The cylinder chain makes the pallet's displacement more precise and controllable, and also makes the pallet more stable when moving. This allows the pallet to be accurately moved to a position flush with the upper or lower conveying component, which facilitates the transfer of the support plate onto the pallet and improves the stability of the lifting component when transferring the support plate.

[0011] Optionally, the return assembly includes a conveyor belt mounted on the pallet, two rotating shafts respectively passing through both ends of the conveyor belt, and a rotating motor for controlling the rotation of the rotating shafts. When the pallet moves upward, the conveying direction of the conveyor belt is the same as that of the upper conveying assembly, and when the pallet moves downward, the conveying direction of the conveyor belt is the same as that of the lower conveying assembly. The conveying assembly and the return assembly have the same structure.

[0012] By adopting the above technical solution, the conveyor belt conveying direction can be changed by using the forward and reverse rotation of the rotating motor, which makes it easier to move the support plate into or out of the tray without having to manually move the support plate into or out of the tray, thus improving the conveying efficiency of the return assembly and the conveying assembly.

[0013] Optionally, one of the two rotating shafts and the output shaft of the rotating motor are provided with a transmission gear, and the two transmission gears are provided with the same transmission chain that meshes with them.

[0014] By adopting the above technical solution, when the rotating motor drives the rotating shaft to rotate, the transmission chain and transmission gear cooperate to drive the rotating shaft to rotate. Compared with the rotating shaft being directly connected to the output shaft of the rotating motor, the rotating shaft is less likely to slip relative to the output shaft of the rotating motor, thereby making the transmission stability of the conveyor belt high and facilitating the transmission of the support plate.

[0015] Optionally, limiting plates are provided on both sides of the conveyor belt, and the distribution direction of the two limiting plates is perpendicular to the conveying direction of the conveyor belt.

[0016] By adopting the above technical solution, when the conveyor belt rotates, the limiting plates located on both sides of the conveyor belt can limit the conveyor belt, making it less likely to deviate when the conveyor belt rotates, thereby stabilizing the rotation trajectory of the conveyor belt. At the same time, it makes the return assembly and the conveying assembly highly stable and the transmission effect on the support plate good.

[0017] Optionally, the frame is provided with a micro switch for controlling the forward and reverse rotation of the rotating motor. The button of the micro switch is provided with a guide slope. When the tray moves up or down, it can abut against the guide slope to trigger the micro switch to control the forward and reverse rotation of the rotating motor.

[0018] By adopting the above technical solution, during the upward movement of the pallet, when the pallet touches the micro switch, it will press the button of the micro switch away from the pallet along the guide slope, thereby activating the micro switch to control the rotating motor to rotate forward. At this time, the conveyor belt's transmission direction is the same as that of the upper conveyor component. During the downward movement of the pallet, when the pallet touches the micro switch, it will activate the micro switch to control the rotating motor to rotate in reverse. At this time, the conveyor belt's transmission direction is the same as that of the lower conveyor component. By automatically controlling the forward and reverse rotation of the rotating motor by touching the micro switch when the pallet moves up and down, the forward and reverse rotation of the rotating motor is achieved without manual operation. This results in a high degree of automation in the conveying mechanism and facilitates the cyclical conveying and utilization of the support plate.

[0019] Optionally, both the upper and lower conveying components include a conveying motor mounted on the frame, a conveying shaft rotatably mounted on the frame, a conveying gear mounted on the conveying shaft, and a conveying chain meshing with the conveying gear. The support plate is placed on the conveying chain, and the conveying motor can control the rotation of the conveying shaft.

[0020] By adopting the above technical solution, when the upper and lower conveying components transport the support plate, the conveying motor first drives the conveying shaft to rotate, then the conveying shaft drives the conveying gear to rotate, the conveying gear then drives the conveying chain to rotate, and finally the conveying chain drives the support plate to move, so that the support plate can move from the input end of the upper or lower conveying component to the output end, ensuring the normal transportation of the support plate, and the chain is not easy to slip relative to the gear, making the transmission reliability of the conveying mechanism strong.

[0021] Optionally, a limiting groove is provided on the frame, and the conveyor chain is slidably disposed in the limiting groove.

[0022] By adopting the above technical solution, when the conveyor motor drives the conveyor chain to rotate, the groove wall of the limiting groove can limit the rotation direction of the conveyor chain, making it less likely for the rotation direction of the conveyor chain to deviate, thereby making the conveying effect of the conveyor chain on the support plate more stable.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The support plate is moved from the output end to the input end of the upper conveying component through the lower conveying component, lifting component, return component and conveying component, saving manpower and improving the transportation efficiency of the conveying mechanism;

[0025] 2. The conveyor cylinder drives the pallet to move up and down through the cylinder chain, which makes the conveyor cylinder occupy little space and saves production space;

[0026] 3. When the pallet moves up and down, a micro switch is triggered to control the forward and reverse rotation of the rotating motor, thereby changing the conveyor belt's direction of transport. This makes it easy to move the support plate into or out of the pallet, and the operation is convenient. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0036] This application discloses a double-layer conveying mechanism.

[0037] Example 1

[0038] Reference Figure 1 and Figure 2 A double-layer conveying mechanism includes a frame 1, an upper conveying assembly 2 and a lower conveying assembly 3 mounted on the frame 1, two sets of lifting assemblies 4 respectively mounted at the input and output ends of the upper conveying assembly 2, and a support plate 7 placed on the upper conveying assembly 2 to support a transformer cover plate. Fixing plates 11 are provided on both sides of the support plate 7 on the frame 1 to restrict the movement direction of the support plate 7, reducing the possibility of the support plate 7 accidentally falling. The upper conveying assembly 2 and the lower conveying assembly 3 have opposite conveying directions and are arranged vertically, with the upper conveying assembly 2 located directly above the lower conveying assembly 3. The output end of the upper conveying assembly 2 is provided with a return assembly 5 for transferring the support plate 7 to the lower conveying assembly 3, and the input end of the upper conveying assembly 2 is provided with a conveying assembly 6 for transferring the support plate 7 to the upper conveying assembly 2.

[0039] Reference Figure 2 Both the upper conveying assembly 2 and the lower conveying assembly 3 include a conveying motor 21 mounted on the frame 1, two conveying shafts 22 rotatably mounted on the frame 1, conveying gears 23 fixed at both ends of the conveying shafts 22, and two conveying chains 24 mounted on the conveying gears 23. The two ends of the conveying chains 24 are respectively fitted onto the conveying gears 23 at both ends of the different conveying shafts 22, and the conveying chains 24 and the conveying gears 23 mesh with each other. The frame 1 is provided with a limiting groove 12 for the conveying chains 24 to be movably mounted therein.

[0040] Reference Figure 2In this embodiment, both the upper conveying assembly 2 and the lower conveying assembly 3 have one conveying motor 21. In other cases, the specific number of conveying motors 21 can be selected according to customer needs. A reducer is connected to the output shaft of the conveying motor 21, and the conveying motor 21 is connected to one of the conveying shafts 22 through the reducer to control the rotation of the conveying shaft 22. The two ends of the support plate 7 are respectively placed on different conveying chains 24. During operation, the conveying motor 21 drives the conveying shaft 22 and the conveying gear 23 to rotate, and the conveying gear 23 drives the conveying chain 24 to rotate. The groove wall of the limiting groove 12 can limit the conveying chain 24, resulting in good transport efficiency.

[0041] Reference Figure 3 The lifting assembly 4 includes a lifting slide rail 41 fixedly mounted on the frame 1 and located on the front and rear sides of the pallet 42, a pallet 42 slidably mounted on the lifting slide rail 41, and a transmission power component 43 mounted on the pallet 42. The pallet 42 has sliding portions 421 on both sides near the lifting slide rail 41. The sliding portions 421 have mounting grooves 422 for the lifting slide rail 41 to extend into. The lifting slide rail 41 slides in conjunction with the mounting grooves 422. The pallet 42 is used to support the support plate 7. The transmission power component 43 is used to control the pallet 42 to move up and down along the lifting slide rail 41.

[0042] Reference Figure 3 and Figure 4 The transmission power component 43 includes a transmission cylinder 431, a transmission shaft 432 fixed on the piston rod of the transmission cylinder 431, transmission gears 433 rotatably mounted at both ends of the transmission shaft 432, and a cylinder chain 434 meshing with the transmission gears 433. A lifting gear 13, higher than the transmission gears 433, is rotatably mounted on the frame 1. The cylinder chain 434 is wound around the transmission gears 433 and the lifting gear 13 and meshes with the lifting gear 13. One end of the cylinder chain 434 is fixed to the sliding part 421, and the other end passes over the lifting gear 13 and the transmission gear 433 and is fixed to the frame 1. With the above configuration, the lifting assembly 4 can move the support plate 7 to a position flush with the transmission gears 23 of the upper conveying assembly 2 and the lower conveying assembly 3, thereby facilitating the transmission of the support plate 7 and improving the transportation efficiency of the conveying mechanism.

[0043] Reference Figure 2 , Figure 3 and Figure 5The return assembly 5 is mounted on the tray 42 at the output end of the upper conveying assembly 2, and the conveying assembly 6 is mounted on the tray 42 at the output end of the lower conveying assembly 3. Both the return assembly 5 and the conveying assembly 6 include two conveyor belts 51 mounted on the tray 42, two rotating shafts 52 passing through both ends of each conveyor belt 51, a rotating motor 53 connected to one of the rotating shafts 52, transmission gears 54 fixed to the output shafts of one of the rotating shafts 52 and the rotating motor 53, and transmission chains 55 meshing with the two transmission gears 54. The tray 42 includes a mounting part 423, on which the rotating shafts 52 and the rotating motor 53 are mounted. The rotating motor 53 changes the conveying direction of the conveyor belts 51 by rotating forward and backward to convey the support plate 7 in different directions.

[0044] The implementation principle of a double-layer conveying mechanism according to an embodiment of this application is as follows: When the support plate 7 reaches the output end of the upper conveying component 2, the pallet 42 at the output end of the upper conveying component 2 will move upward under the action of the transmission power component 43. At this time, the transport direction of the conveyor belt 51 is consistent with that of the upper conveying component 2. After the support plate 7 is transferred to the pallet 42, the pallet 42 will move down to a position level with the conveyor chain 24 in the lower conveying component 3. Then, the rotating motor 53 reverses, so that the transport direction of the conveyor belt 51 is consistent with that of the lower conveying component 3, so as to transport the support plate 7 to the conveyor chain 24 of the lower conveying component 3. The lower conveying component 3 transfers the support plate 7 to the pallet 42 at the output end, and under the action of the transmission power component 43, moves it to the conveyor chain 24 of the upper conveying component 2 in the same way for the next transfer. By moving the support plate 7 from the output end to the input end of the upper conveying component 2 in the above manner, both manpower is saved and the conveying efficiency of the conveying mechanism is improved.

[0045] Example 2

[0046] Reference Figure 6 The difference between this embodiment and Embodiment 1 is that: the conveyor belt 51 is provided with limiting plates 56 on both sides perpendicular to its conveying direction, and the limiting plates 56 are fixedly mounted on the mounting part 423. The two limiting plates 56 can limit the movement direction of the conveyor belt 51, so that the operation of the conveyor belt 51 is stable, thereby improving the transportation effect of the support plate 7.

[0047] Reference Figure 6Microswitches 14 are provided on the two side walls of the frame 1 away from the upper conveying component 2. The microswitches 14 are located on the side of the frame 1 near the tray 42. The microswitches 14 are used to control the forward and reverse rotation of the rotating motor 53. The button of the microswitches 14 is provided with a guide slope 141. When the tray 42 moves up or down along the lifting slide rail 41, it can press against the guide slope 141, thereby squeezing the button away from the tray 42, triggering the microswitches 14, and controlling the forward and reverse rotation of the rotating motor 53.

[0048] The implementation principle of a double-layer conveying mechanism in this application embodiment is as follows: When the pallet 42 moves upward and triggers the micro switch 14, the rotating motor 53 rotates forward, and the conveying direction of the conveyor belt 51 is the same as that of the upper conveying component 2, which facilitates the support plate 7 to move from the upper conveying component 2 to the pallet 42 or from the pallet 42 to the upper conveying component 2; when the pallet 42 moves downward and triggers the micro switch 14, the rotating motor 53 reverses, and the conveying direction of the conveyor belt 51 is the same as that of the lower conveying component 3, which facilitates the support plate 7 to move from the lower conveying component 3 to the pallet 42 or from the pallet 42 to the lower conveying component 3, thereby improving the conveying efficiency of the conveying mechanism.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
