Detailed implementation mode

[0028] Embodiment 1

[0029] As Figures 2 to 4 shown, an automatic feeding device includes a diversion plate 4 and a discharging member 5. The diversion plate 4 and the discharging member 5 are both located inside the main box body 1. The top of the main box body 1 is connected with a feeding box 2. The top of the feeding box 2 is provided with a funnel-shaped feeding port, and the bottom is connected with a discharge hopper 201. A partition board 3 is arranged inside the main box body 1. A cavity is formed by enclosing between the feeding box 2 and the partition board 3. A discharging member 5 and a driving assembly are arranged in the cavity.

[0030] As Figure 4 shown, the discharging member 5 is internally provided with a plurality of discharging grooves 501, and a plurality of pushing grooves 502 communicating with the discharging grooves 501 are arranged at the top. Among them, the discharging grooves 501 are used for stacking the workpieces 100; a pressing block 12 that can move up and down is arranged in the pushing grooves 502, and is used for pushing the workpieces 100 in the discharging grooves 501 out along the discharging grooves 501.

[0031] As Figures 3 to 6 shown, a diversion plate 4 is installed at the position of the main box body 1 corresponding to the discharging grooves 501, and a diversion groove 401 adapted to the discharging grooves 501 is arranged on the diversion plate 4. The diversion plate 4 is used for receiving the workpieces 100 falling from the feeding box 2 and driving the workpieces 100 to be clamped in the diversion grooves 401 through the vibration of the diversion plate 4, so that the workpieces 100 enter the discharging grooves 501 through the diversion grooves 401 to achieve vertical arrangement.

[0032] As Figure 5 shown, in this embodiment, the diversion plate 4 is vibrated by a vibration motor (not shown in the figure), and a first spring 403 is further arranged at the bottom of the diversion plate 4. In addition, in order to prevent the workpieces 100 falling from the feeding box 2 from directly entering the discharging grooves 501, a baffle 402 is installed at the position of the partition board 3 corresponding to the discharging grooves 501.

[0033] As Figure 2 、Figure 3 As shown in the figure, the driving assembly includes a first motor 6, a transmission assembly 7, a first screw rod 8, a first slider 9, a lifting plate 10, a connecting rod 11, and a pressing block 12.

[0034] The first motor 6 drives the first screw rod 8 to rotate through the transmission assembly 7. The transmission assembly 7 includes a transmission gear and a transmission rack. The first slider 9 is sleeved on the first screw rod 8. The lifting plate 10 is connected to the first slider 9. The lifting plate 10 is connected to the pressing block 12 through the connecting rod 11.

[0035] The first motor 6 drives the first screw rod 8 to rotate through the transmission assembly, causing the first slider 9 to move up and down along the first screw rod 8, driving the lifting plate 10, the connecting rod 11, and the pressing block 12 to move up and down. The workpiece 100 is pushed to fall along the discharge chute 501 by the downward movement of the pressing block 12.

[0036] As Figure 4 , Figure 7 As shown in the figure, a bottom plate 503 is connected to the bottom of the discharging member 5. A fixing block 504, a second spring 505, and a movable plate 506 are arranged inside the bottom plate 503. One end of the movable plate 506 is hinged to the side wall of the material pushing chute 502. The movable plate 506 is connected to the side wall of the bottom plate 503 through the second spring 505 and the fixing block 504.

[0037] Relying on the elastic force of the second spring 505 to provide a supporting force for the workpiece 100 in the material pushing chute 502. When the pressing block 12 pushes the workpiece 100 to move downward, the second spring 505 is compressed to drive the movable plate 506 to move, so that the workpiece 100 falls. The material tray 200 is placed below the bottom plate 503, and the workpiece 100 falling from the discharge chute 501 can be received.

[0038] It should be noted that the size of the diversion chute 401 is adapted to the workpiece 100, so that the workpiece 100 can be arranged in sequence in the diversion chute 401. The size of the discharge chute 501 is adapted to the workpiece 100 and the material tray 200, so that the workpiece 100 can be neatly stacked in the discharge chute 501, and the workpiece 100 can be neatly arranged in the material tray 200 when falling along the discharge chute 501.

[0039] Embodiment 2

[0040] As Figure 2 shown in the figure, the structure of this embodiment is basically the same as that in Embodiment 1. The difference is that: in this embodiment, two discharging members 5 are arranged in relative distribution. Correspondingly, there are two discharging hoppers 201 and two diversion plates 4. The discharging hopper 201 is located above the diversion plate 4.

[0041] In addition, a rotating rod 202 and a stirring rod 203 are installed inside the feeding box 2. The stirring rod 203 is installed on the rotating rod 202, and the rotating rod 202 is connected to the first screw 8. When the first screw 8 rotates, it can drive the rotating rod 202 to rotate, so that the stirring rod 203 can dial the workpiece 100 in the feeding box 2 to the discharge hopper 201 and drop it. Adjusting the number of the stirring rods 203 can control the falling rate of the workpiece 100 from the discharge hopper 201. As Figure 2 shown, a chevron-shaped auxiliary block is connected to the top of the rotating rod 202, which is used to divert the workpiece 100 entering the feeding box 2 from the feeding port to both sides, facilitating the stirring rod 203 to dial the material.

[0042] Working principle: For this automatic feeding device, when in use, the workpiece 100 enters the feeding box 2 from the feeding port, and the chevron-shaped auxiliary block diverts the workpiece 100 to both sides. The first motor 6 drives the first screw 8 and the rotating rod 202 to rotate through the transmission assembly 7, so that the stirring rod 203 on the rotating rod 202 dials the workpiece 100 in the feeding box 2 to the discharge hopper 201, and it falls onto the diversion plate 4 through the discharge hopper 201.

[0043] The diversion plate 4 vibrates to make the workpiece 100 neatly arranged in the diversion groove 401, and the inclined diversion plate 4 enables the neatly arranged workpiece 100 to fall into the discharge groove 501 in sequence and stack. At this time, the second spring 505 supports the movable plate 506 to provide a supporting force for the workpiece 100 to prevent the workpiece 100 from falling.

[0044] When the workpiece 100 is stacked to a certain height, when the first screw 8 rotates and drives the lifting plate 10 to move downward, the pressing block 12 pushes the workpiece 100 to compress the second spring 505, so that the workpiece 100 can fall along the discharge groove 501 into the tray 200 below the bottom plate 503, realizing the one-time feeding of the tray 200.

[0045] Embodiment III

[0046] As Figure 8 shown, the structure of this embodiment is basically the same as that in Embodiment II, and the difference lies in that: in this embodiment, a first transmission assembly 17, a second transmission assembly 18 and a second screw 13 are provided. The first transmission assembly 17 is used for the feeding transmission of the tray 200, and the second transmission assembly 18 is used for the discharging transmission of the tray 200.

[0047] Two sliders 14 are sleeved on the second screw 13. The thread directions at both ends of the second screw 13 are opposite. When the second screw 13 rotates with the second motor 15, the two sliders 14 can move relatively closer or relatively farther away. Among them, two relatively distributed push plates 16 are connected to the slider 14. When the push plates 16 are located at the bottom of the discharging member 5, they are used to limit the position of the tray 200. In addition, a telescopic cylinder 19 is installed on the slider 14, which is used to abut against the tray 200 for positioning or to push the tray 200 for transportation.

[0048] As Figure 9 shown, the first transfer component 17 includes a conveyor belt 1701, side plates 1702 and a limit plate 1703. Side plates 1702 are installed on both sides of the conveyor belt 1701, and a limit plate 1703 is connected to the side plates 1702. The limit plate 1703 is used to define the movement trajectory of the tray 200 on the conveyor belt 1701 to prevent the tray 200 from being misaligned during movement. Among them, the structure of the second transfer component 18 is the same as that of the first transfer component 17, and will not be elaborated here.

[0049] As Figure 8 shown, the empty tray 200 is transferred by the first transfer component 17 to the lower part of the discharging member 5. At this time, the pushing plate 16 and the telescopic cylinder 19 can limit the position of the tray 200, so that the workpieces 100 in the discharging member 5 can fall into the tray 200 neatly arranged.

[0050] After the loading is completed, the second motor 15 drives the second screw 13 to rotate, so that the two second sliders 14 move to both sides to the position of the second transfer component 18 respectively. The telescopic cylinder 19 pushes the tray 200, so that the second transfer component 18 can receive the tray 200 to realize discharging and transferring. Among them, when the pushing plate 16 moves the tray 200, it can ensure the stability of the movement trajectory of the tray 200.

[0051] After the transfer is completed, the second motor 15 drives the second screw 13 to reverse, and the two second sliders 14 can be reset to the lower part of the discharging member 5.

[0052] Adjusting the transfer speed of the first transfer component 17, the transfer speed of the second transfer component 18, the rotation speed of the second motor 15, the rotation speed of the first motor 6, and the transmission ratio of the transmission component 7 can make the feeding time of the tray 200, the loading time of the workpiece 100, and the discharging time of the tray 200 cooperate with each other, reduce the time loss between operations, and realize the fully automatic and fast feeding of the workpiece 100.

[0053] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
