[0002] In the production process of push-button switches, continuous and stable feeding of the push-button handles is required to facilitate subsequent assembly processes. For this purpose, a feeding device is typically used to circulate the push-button handles.

[0065] This embodiment provides a feeding device, such as... Figures 1-4As shown, the feeding device includes a support frame, a conveying mechanism 200, and a lifting mechanism 300. The conveying mechanism 200 includes a first conveying component 210 and a second conveying component 220. The first conveying component 210 is disposed on the first layer of the frame 100, and the second conveying component 220 is disposed on the second layer of the frame 100 and located above the first conveying component 210. The conveying directions of the first conveying component 210 and the second conveying component 220 are opposite. The first layer of the frame 100 has a feeding station and a lifting station sequentially arranged along the conveying direction of the first conveying component 210. The second layer of the frame 100 has a discharging station and a stacking station sequentially arranged along the conveying direction of the second conveying component 220. The lifting mechanism 300 is disposed on the frame 100. Near the lifting station, the lifting end of the lifting mechanism 300 can move vertically between the lifting station and the discharge station. During feeding, multiple stacked trays 10 are placed at the feeding station manually or by a handling device. Each tray 10 contains multiple materials 20. The first conveying component 210 transports the stacked trays 10 from the feeding station to the lifting station. The lifting mechanism 300 transports the stacked trays 10 from the lifting station to the discharge station via the lifting end. The second conveying component 220 transports the empty trays in the stacked trays 10 to the stacking station. Through the above design, the trays 10 can be transported in an orderly cycle in the vertical space, making the overall structure more compact and the space utilization rate higher.

[0066] Optionally, such as Figure 5 , Figure 6 and Figure 7 As shown, the second conveying assembly 220 includes a handling assembly 221 and a second conveying line 222. The handling assembly 221 includes a linear drive 2211 and a robot arm 2212. Linear drives 2211 are respectively provided on both sides of the discharge station along the conveying direction of the second conveying assembly 220. Each linear drive 2211 has a robot arm 2212 at its output end. The two robots 2212 can respectively clamp onto both sides of the empty tray. The second conveying line 222 is located at the stacking station. The handling assembly 221 is used to convey the empty tray to the second conveying line 222, and the second conveying line 222 is used to convey the empty tray to the stacking station. Through this design, the empty tray is conveyed in two segments, which avoids interference between the second conveying assembly 220 and the multiple stacked trays 10 at the discharge station, improving the reliability of the conveying process.

[0067] Optionally, the linear drive 2211 can be a rodless cylinder. Rodless cylinders operate smoothly and move quickly, significantly improving the conveying efficiency of the empty material tray and ensuring the stability and positioning accuracy of the material tray 10 during handling. In other embodiments, the linear drive 2211 can also be a linear motor. Linear motors have high response speed and controllability, further improving handling accuracy and conveying efficiency, while adapting to different production cycles and process requirements.

[0068] Optionally, grooves 11 are provided on both sides of the material tray 10. The robot arm 2212 includes a gripper cylinder and a first gripper. The first gripper is connected to the piston rod of the gripper cylinder. The gripper cylinder can drive the first gripper to insert into the corresponding groove 11, thereby realizing reliable gripping and stable conveying of the material tray 10.

[0069] Optionally, such as Figure 7 As shown, the second conveyor line 222 includes multiple second rollers 2221, a second transmission belt, and a second conveying drive. The multiple second rollers 2221 are spaced apart at the stacking station along the conveying direction of the second conveying assembly 220. Adjacent second rollers 2221 are connected by the second transmission belt. One of the multiple second rollers 2221 is connected to the output end of the second conveying drive, thereby providing power input to the second conveyor line 222 and ensuring that the second conveyor line 222 stably conveys empty trays to the stacking station. Optionally, the second conveying drive can be a drive motor.

[0070] Specifically, each second roller 2221 has a second groove 22211 at its first end. The second transmission belt is wound around the two second grooves 22211 of two adjacent second rollers 2221 and is tensioned to ensure reliable power transmission. In this embodiment, two adjacent second rollers 2221 are connected by at least two second transmission belts to ensure the stability and reliability of power transmission. In other embodiments, the number of second transmission belts can be flexibly set according to actual needs, and there is no specific limitation on the number of second transmission belts.

[0071] Optionally, such as Figure 5 and Figure 7 As shown, along the conveying direction of the second conveyor line 222, the end of the second conveyor line 222 is provided with a second free roller 2222. The second free roller 2222 can rotate around its own axis, thereby effectively buffering the motion inertia of the empty material tray, reducing the impact force on the material tray 10, and ensuring the stability and safety of the material tray 10 during the conveying process to the stacking station.

[0072] Optionally, the feeding device also includes a stacking mechanism 400, which is located at the stacking station. The stacking station has an outlet at the end away from the discharge station. Baffles 401 are provided at the end of the stacking station near the discharge station and on both sides of the stacking station to ensure that multiple empty trays are arranged neatly and orderly at the stacking station and to facilitate the removal of multiple stacked empty trays, thereby improving the convenience of operation.

[0073] Optionally, such as Figure 5 and Figure 8As shown, the feeding device also includes a stacking mechanism 400, which includes a support drive component 410, a mounting block 420, a support block 430, and an elastic component. Support drive components 410 are provided on both sides of the stacking station. Each support drive component 410 has a mounting block 420 at its output end. The bottom of the support block 430 is rotatably connected to the mounting block 420, and the top of the support block 430 is elastically connected to the mounting block 420 through the elastic component. From bottom to top, the support block 430 is inclined towards the inside of the stacking station. The lifting component 440 is used to lift the empty material tray upward onto the support block 430. Each time an empty pallet arrives, the lifting assembly 440 performs a lifting action, causing multiple empty pallets to stack on the support block 430. After a certain number are stacked, the support drive component 410 drives the mounting block 420 and the support block 430 to retract, and the lifting assembly 440 rises again, which can smoothly place the stack of empty pallets onto the second conveyor line 222. The second conveyor line 222 continues to transport the stack of empty pallets from the stacking station.

[0074] Optionally, the lower end of the baffle 401 is inclined toward the outside of the stacking station to form a flared structure, so as to avoid interference between the material tray 10 and the baffle 401 when it moves upward, thereby improving the reliability and smoothness of stacking empty material trays.

[0075] Optionally, the feeding device further includes a second stop assembly 520, which includes a second stop drive 521 and a second stop 522. The second stop drive 521 is disposed at one end of the second conveying assembly 220 near the stacking station. The second stop 522 is connected to the output end of the second stop drive 521. The second stop drive 521 drives the second stop 522 to move vertically, so that the second stop 522 stops the empty tray at the stacking station and is located above the lifting assembly 440, so that the lifting assembly 440 lifts the empty tray upward onto the support block 430. This design prevents the empty tray from detaching from the end of the second conveying line 222, improving the reliability of the conveying. In this embodiment, the second stop drive 521 is a stop cylinder, which operates smoothly, with low noise and high reliability.

[0076] Optionally, the lifting assembly 440 includes a lifting frame 442 and a lifting cylinder 441. The lifting frame 442 is located between the stacking station and the loading station, and the lifting frame 442 is connected to the output end of the lifting cylinder 441. By actuating the lifting cylinder 441, the empty material tray can be lifted onto the support block 430.

[0077] Optionally, the first conveying assembly 210 extends from the feeding station to the lifting station. The first conveying assembly 210 includes a plurality of first rollers 211, a first transmission belt, and a first conveying drive. The plurality of first rollers 211 are spaced apart along the conveying direction of the first conveying assembly 210. Adjacent first rollers 211 are connected by the first transmission belt. One of the plurality of first rollers 211 is connected to the output end of the first conveying drive, thereby providing power input to the first conveying assembly 210 and ensuring that the tray 10 carrying the material 20 moves from the feeding station to the lifting station.

[0078] In this embodiment, each of the first rollers 211 has a first groove at its first end. The first transmission belt is wound around and tensioned within the two first grooves of two adjacent second rollers 2221 to ensure reliable power transmission. In this embodiment, two adjacent first rollers 211 are connected by at least two first transmission belts to ensure the stability and reliability of power transmission. In other embodiments, the number of first transmission belts can be flexibly set according to actual needs, and there is no specific limitation on the number of first transmission belts.

[0079] Optionally, along the conveying direction of the first conveying assembly 210, the starting end of the first conveying assembly 210 is provided with a first free roller 212, which can rotate around its own axis, thereby improving the convenience of feeding.

[0080] Optionally, the starting end of the first conveying assembly 210 is further provided with a first stop assembly 510. After multiple stacked trays 10 are placed at the feeding station, the first stop assembly 510 is used to prevent the multiple stacked trays 10 from detaching from the starting end of the first conveying assembly 210, thereby improving the safety of the conveying process. The structure of the first stop assembly 510 is the same as that of the second stop assembly 520, and will not be described in detail.

[0081] Optionally, such as Figure 9 As shown, the lifting mechanism 300 includes a first linear motion component 310 and a bracket 320. The first linear motion component 310 is vertically disposed at one end of the frame 100 near the lifting station. The bracket 320 is disposed on the moving end of the first linear motion component 310. The bracket 320 can pass through the first conveying component 210 and move to below the lifting station, thereby enabling the first conveying component 210 to convey multiple stacked material trays 10 to the lifting station. This avoids interference between the bracket 320 and the first conveying component 210 during the conveying process, ensuring the smooth operation of the lifting mechanism 300, improving the safety and stability of the material trays 10 during the transfer process, and making the spatial structure more compact, further improving the space utilization rate.

[0082] Optionally, the first linear motion component 310 includes a lead screw and nut assembly and a lifting motor. The input end of the lead screw and nut assembly is connected to the output end of the lifting motor, and the output end of the lead screw and nut assembly is provided with a bracket 320. In other embodiments, the first linear motion component 310 includes a gear and rack assembly and a lifting motor. The gear and rack assembly is arranged vertically, the output end of the lifting motor is connected to the input end of the gear and rack assembly, and the bracket 320 is connected to the output end of the gear and rack assembly. It should be noted that the lead screw and nut assembly and the gear and rack assembly are both prior art, and their specific structures will not be described in detail here.

[0083] Optionally, the bracket 320 includes a first mounting plate 321, a first side plate 322, a second side plate 323, and a plurality of rods 324. The first mounting plate 321 is connected to the moving end of the first linear motion assembly 310. The first side plate 322 and the second side plate 323 are disposed opposite to each other on the first mounting plate 321. The first side plate 322 and the second side plate 323 are respectively provided with a first clearance groove 3221 and a second clearance groove 3231 at positions corresponding to the first roller 211. The plurality of rods 324 are spaced apart on the bracket 320, and the two ends of each rod 324 are respectively connected to the first roller 211. One side plate 322 is connected to the second side plate 323 so that the rod 324 can pass through the gap between the two first rollers 211 and move to the bottom of the lifting station, ensuring the stability and reliability of the bracket 320 when lifting the material tray 10. At the same time, the setting of the first clearance groove 3221 and the second clearance groove 3231 further improves the fit between the bracket 320 and the first conveying component 210, making the structure more compact and reasonable. This not only improves the operating efficiency of the lifting mechanism 300, but also ensures the stability and safety of the entire feeding device during continuous operation.

[0084] Optionally, a carrier (not shown) is provided near the discharge station on the frame 100. The feeding device also includes a feeding mechanism 600, which includes a second linear motion component 610 and a handling gripper 620. The second linear motion component 610 is located at the top of the frame 100 and above the discharge station. The handling gripper 620 is connected to the moving end of the second linear motion component 610. The second linear motion component 610 drives the handling gripper 620 to transport the material 20 in the tray 10 at the discharge station to the carrier. Through the above design, manual handling operations are avoided, which not only reduces labor intensity and labor costs, but also improves the efficiency and stability of the handling process. At the same time, the handling gripper 620 runs smoothly under the drive of the second linear motion component 610, which can ensure the accuracy and consistency of material 20 transfer, thereby further improving the automation level of the entire feeding device and the continuous operation capability of the production line.

[0085] Optionally, the second linear motion assembly 610 includes a second motor 611, a driving wheel 612, a driven wheel 613, and a belt 614. The driving wheel 612 and the driven wheel 613 are spaced apart along a second direction. The belt 614 is wound around the outer periphery of the driving wheel 612 and the driven wheel 613 and is tensioned. The second motor 611 is connected to the driving wheel 612 in a transmission connection. The handling gripper 620 is fixed on the belt 614. With the above design, the second linear motion assembly 610 uses the second motor 611 to drive the driving wheel 612 to rotate, thereby driving the belt 614 to circulate between the driving wheel 612 and the driven wheel 613. The handling gripper 620 fixed on the belt 614 can then reciprocate along the second direction, realizing the rapid and precise handling of the material 20 in the material tray 10 at the discharge station.

[0086] Optionally, the handling gripper 620 includes a second cylinder 621, the piston rod of the second cylinder 621 is arranged vertically downward, and multiple second grippers 622 are fixed on the piston rod, which can handle multiple materials 20 at one time, thereby improving handling efficiency.

[0087] Optionally, the feeding device also includes a protective box 700, which is installed outside the frame 100 to prevent operators from accidentally entering the work area during equipment operation and causing accidents, thus significantly improving the safety of the feeding device. At the same time, the protective box 700 can also protect the key components inside the equipment from dust, extend the service life of the components, and ensure the stability and reliability of the feeding device in long-term operation.

[0088] Specifically, the feeding process of the feeding device provided in this embodiment is roughly as follows:

[0089] First, multiple stacked trays 10 are placed at the feeding station. Each tray 10 contains multiple materials 20, which are arranged in an array within the tray 10.

[0090] Then, the first conveying component 210 moves to transport the stacked trays 10 to the lifting station. The first linear motion component 310 of the lifting mechanism 300 drives the bracket 320 to move in the vertical direction, lifting the stacked trays 10 upward to the discharge station. The second linear motion component 610 uses the second motor 611 to drive the drive wheel 612 to rotate, thereby driving the belt 614 to circulate between the drive wheel 612 and the driven wheel 613. The handling gripper 620 fixed on the belt 614 can then reciprocate along the second direction, realizing the rapid and accurate handling of the material 20 in the tray 10 at the discharge station.

[0091] When the topmost tray 10 among the stacked trays 10 is empty (i.e., the tray 10 is called an empty tray), the lifting mechanism 300 drives the bracket 320 to move downwards, so that the height of the empty tray is the same as the height of the robotic arms 2212 on the conveying assembly 221. The two robotic arms 2212 are inserted into the grooves 11 on both sides of the empty tray to clamp the tray 10. Then the conveying assembly 221 moves to transport the empty tray to the second conveyor line 222. The second conveyor line 222 moves to transport the empty tray to the stacking station. The second stop 522 stops the empty tray at the stacking station and is located above the lifting assembly 440.

[0092] Finally, the lifting component 440 moves to lift the empty material tray upwards onto the support block 430, completing the stacking of a single empty material tray. Repeating the above steps allows the empty material trays to be stacked on the stacking mechanism 400. After a certain number are stacked, the support drive component 410 drives the mounting block 420 and the support block 430 to retract, and the lifting component 440 rises again, which can smoothly place the stack of empty material trays onto the second conveyor line 222.
