Detailed Implementation

[0028] Example 1

[0029] like Figures 2 to 4 As shown, an automatic feeding device includes a flow guide plate 4 and a discharge component 5. Both the flow guide plate 4 and the discharge component 5 are located inside a main housing 1. A feed box 2 is connected to the top of the main housing 1, with a bucket-shaped feed inlet at the top and a discharge hopper 201 connected to the bottom. A partition 3 is provided inside the main housing 1, forming a cavity between the feed box 2 and the partition 3. The discharge component 5 and a drive assembly are disposed within this cavity.

[0030] like Figure 4 As shown, the material discharge component 5 has multiple material discharge slots 501 inside, and multiple material pusher slots 502 connected to the material discharge slots 501 are opened on the top. Among them, the material discharge slots 501 are used for stacking workpieces 100; the material pusher slots 502 are equipped with pressing blocks 12 that can move up and down, which are used to push the workpieces 100 in the material discharge slots 501 out along the material discharge slots 501.

[0031] like Figures 3 to 6 As shown, a guide plate 4 is installed at the position of the main box 1 corresponding to the discharge trough 501. The guide plate 4 has a guide groove 401 adapted to the discharge trough 501. The guide plate 4 is used to receive the workpiece 100 falling from the feed box 2, and the vibration of the guide plate 4 drives the workpiece 100 to be clamped in the guide groove 401, so that the workpiece 100 enters the discharge trough 501 through the guide groove 401 to achieve vertical arrangement.

[0032] like Figure 5 As shown in the figure, in this embodiment, the vibration motor (not shown) drives the guide plate 4 to vibrate, and a spring 403 is also provided at the bottom of the guide plate 4. In addition, in order to prevent the workpiece 100 falling from the feed box 2 from directly entering the discharge chute 501, a baffle 402 is installed on the partition 3 at the position corresponding to the discharge chute 501.

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

[0034] Motor one 6 drives screw one 8 to rotate through transmission assembly 7, which includes transmission gears and transmission racks. Slider one 9 is sleeved on screw one 8, lifting plate 10 is connected with slider one 9, and lifting plate 10 is connected with pressing block 12 through connecting rod 11.

[0035] Motor one 6 drives screw one 8 to rotate through transmission assembly, so that slider one 9 moves up and down along screw one 8, driving lifting plate 10, connecting rod 11, and pressing block 12 to move up and down. Pressing block 12 moves downward to push workpiece 100 to fall along discharge chute 501.

[0036] As shown in Figure 4 , Figure 7 The bottom of discharge member 5 is connected with bottom plate 503, the inside of bottom plate 503 is configured with fixed block 504, spring two 505, and movable plate 506. One end of movable plate 506 is hinged with the sidewall of pushing chute 502, and movable plate 506 is connected with the sidewall of bottom plate 503 through spring two 505 and fixed block 504.

[0037] The elastic force of spring two 505 provides support force for workpiece 100 in pushing chute 502. When pressing block 12 pushes workpiece 100 to move downward, spring two 505 is compressed to drive movable plate 506 to move, so that workpiece 100 falls. Placing tray 200 below bottom plate 503 can receive workpiece 100 falling from discharge chute 501.

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

[0039] Example Two

[0040] As shown in Figure 2 The structure of the present embodiment is basically the same as that of example one, and the difference lies in that two discharge members 5 are arranged in the present embodiment, and correspondingly, two discharge hoppers 201 and two drainage plates 4 are arranged. Discharge hopper 201 is located above drainage plate 4.

[0041] In addition, the inside of the feeding box 2 is provided with a rotating rod 202 and stirring rods 203, the stirring rods 203 are installed on the rotating rod 202, the rotating rod 202 is connected with the screw rod 1, when the screw rod 1 rotates, the rotating rod 202 can be driven to rotate, so that the stirring rods 203 can push the workpieces 100 in the feeding box 2 to the discharge hopper 201. The number of the stirring rods 203 can control the falling speed of the workpieces 100 from the discharge hopper 201. As shown in Figure 2 The top of the rotating rod 202 is connected with a herringbone auxiliary block, which is used to guide the workpieces 100 entering the feeding box 2 from the feeding port to the two sides, so as to facilitate the stirring rods 203 to push the workpieces.

[0042] Working principle: when the automatic feeding device is used, the workpieces 100 enter the feeding box 2 from the feeding port, and are guided to the two sides by the herringbone auxiliary block. The motor 6 drives the screw rod 1 and the rotating rod 202 to rotate through the transmission assembly 7, so that the stirring rods 203 on the rotating rod 202 push the workpieces 100 in the feeding box 2 to the discharge hopper 201, and then the workpieces 100 fall on the guide plate 4.

[0043] The workpieces 100 are arranged in the guide groove 401 by the vibration of the guide plate 4, and the workpieces 100 arranged in the guide groove 401 fall into the discharge groove 501 in sequence and are stacked by the guide plate 4 arranged in an inclined manner. At this time, the spring 2 provides support for the workpieces 100, so as to avoid the workpieces 100 from falling.

[0044] When the workpieces 100 are stacked to a certain height, the screw rod 1 rotates to drive the lifting plate 10 to move downward, the pressing block 12 pushes the workpieces 100 to compress the spring 2, so that the workpieces 100 can fall along the discharge groove 501 to the tray 200 below the bottom plate 503, and the tray 200 is loaded once.

[0045] Embodiment three

[0046] As shown in Figure 8 The structure of the embodiment is basically the same as that of the second embodiment, and the difference is that the embodiment is provided with a transmission assembly 1, a transmission assembly 2 and a screw rod 2. The transmission assembly 1 is used for the feeding transmission of the tray 200, and the transmission assembly 2 is used for the discharging transmission of the tray 200.

[0047] The screw rod 2 is sleeved with two sliding blocks 2, the screw rod 2 has opposite screw directions at two ends, and the two sliding blocks 2 can move relatively close to or relatively far away from each other when the screw rod 2 rotates with the motor 2. The two sliding blocks 2 are connected with two push plates 1 distributed oppositely, and the push plates 1 are located at the bottom of the discharge member 5 to limit the position of the tray 200. In addition, the sliding blocks 2 are installed with telescopic cylinders 9 for abutting against the tray 200 to realize positioning or for pushing the tray 200 to realize transfer.

[0048] As shown in Figure 9 The transmission assembly 17 includes a transmission belt 1701, side plates 1702 and limiting plates 1703. The side plates 1702 are installed on both sides of the transmission belt 1701, and the limiting plates 1703 are connected to the side plates 1702, which are used to define the movement track of the tray 200 on the transmission belt 1701, avoiding the tray 200 from being misaligned during movement. The structure of the transmission assembly 18 is the same as that of the transmission assembly 17, and will not be described here.

[0049] As shown in Figure 8 The empty tray 200 is transmitted to the lower side of the material arranging part 5 by the transmission assembly 17, and at this time, the push plate 16 and the telescopic cylinder 19 can define the position of the tray 200, so that the workpieces 100 in the material arranging part 5 can be arranged neatly and fall into the tray 200.

[0050] After the loading is completed, the screw rod 13 is driven to rotate by the motor 15, so that the two sliding blocks 14 move to the positions of the transmission assembly 18, and the tray 200 is pushed by the telescopic cylinder 19, so that the transmission assembly 18 can receive the tray 200 to realize the unloading transmission. During the movement of the tray 200, the push plate 16 can ensure the stability of the movement track of the tray 200.

[0051] After the transfer is completed, the screw rod 13 is reversed by the motor 15, so that the two sliding blocks 14 are reset to the lower side of the material arranging part 5.

[0052] Adjusting the transmission speed of the transmission assembly 17, the transmission speed of the transmission assembly 18, the rotation rate of the motor 15, the rotation rate of the motor 6, and the transmission ratio of the transmission assembly 7 can make the tray 200 loading, the workpieces 100 loading, and the tray 200 unloading time coordinated, reduce the time loss between operations, and realize the full-automatic and rapid loading of the workpieces 100.

[0053] The above only describes the preferred embodiments of the present application, and is not used to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacements to some technical features.
