When the workpiece 4 is intermittently output from the discharge port 21b, by moving the conveyor belt 34 at a uniform speed or moving the conveyor belt 34 intermittently at the frequency at which the workpiece 4 is output from the discharge port 21b, the workpiece 4 falling onto the conveyor belt 34 can be automatically and neatly arranged on the conveyor belt 34 to facilitate subsequent operations of picking up the workpiece 4.

[0081] In some embodiments, the conveying assembly 3 is in the shape of an inclined plate, and the higher end of the conveying assembly 3 is located below the discharge port 21b.

[0083] In some embodiments, the number of guide rods 25 is one, and the peripheral wall of the guide rod 25 is shaped like the inner peripheral wall of the workpiece 4; in some embodiments, the number of guide rods 25 may also be multiple, and the peripheral wall of each guide rod 25 abuts against the inner peripheral wall or the outer peripheral wall of the workpiece 4 to limit the deflection of the workpiece 4 relative to the mounting member 24, and at the same time allow the workpiece 4 to slide relative to the guide rod 25; in some embodiments, the guide rod 25 is provided with a receiving groove along its own length direction (not shown in the figure), and several workpieces 4 are stacked in the receiving groove along the length direction of the guide rod 25, and the workpiece 4 slides with the receiving groove along the length direction of the guide rod 25 to improve the sliding stability of the workpiece 4.

[0084] Reference Figure 2 Specifically, in some embodiments, the storage chamber 21a is opened inside the storage seat 21, the length direction of the storage chamber 21a is arranged along the vertical direction X, and the upper end of the storage chamber 21a is open; when clamping the workpiece 4, the mounting member 24 can be turned over first, so that the length direction of the guide rod 25 is arranged along the horizontal direction or the end of the guide rod 25 away from the mounting member 24 is arranged upward, and then a plurality of workpieces 4 are sleeved on the guide rod 25, and then the storage seat 21 is sleeved on the guide rod 25 by the end of the guide rod 25 away from the mounting member 24, so that the workpiece 4 on the guide rod 25 can be clamped. Located in the storage chamber 21a; finally, adjust the angle of the storage seat 21 so that the storage seat 21 is in a state where the open end of the storage chamber 21a is set upward. At this time, the mounting member 24 abuts against the upper end wall of the storage seat 21, and the distance between the end wall of the guide rod 25 away from the mounting member 24 and the bottom wall of the storage chamber 21a is greater than or equal to the thickness of a single workpiece 4; the workpiece 4 in the storage chamber 21a automatically slides toward the bottom wall of the storage chamber 21a under the action of its own gravity, and the workpiece 4 located at the lowest position breaks away from the guide rod 25 and abuts against the bottom wall of the storage chamber 21a.

[0085] Furthermore, in some embodiments, the storage seat 21 is provided with a positioning groove 21c, and the positioning groove 21c is plugged and matched with the mounting member 24. Specifically, the positioning groove 21c is provided on the upper end wall of the storage seat 21, and the positioning groove 21c is communicated with the storage chamber 21a; the mounting member 24 is plugged into the positioning groove 21c, so that the peripheral wall of the mounting member 24 fits with the inner peripheral wall of the positioning groove 21c, which can limit the movement of the mounting member 24 relative to the storage seat 21 in the horizontal direction, thereby facilitating the positioning accuracy of the guide rod 25 relative to the inner wall of the storage chamber 21a, so that the workpiece 4 and the inner wall of the storage chamber 21a can be kept separated, thereby facilitating the workpiece 4 to automatically slide downward under the action of its own gravity.

[0086] In some embodiments, the blanking assembly 2 further includes a blanking drive 26, which is disposed on the storage seat 21 and is configured to provide a force to move the workpiece 4 toward the discharge port 21b along the vertical direction X. Specifically, the blanking drive 26 is a structure including a counterweight block, and the blanking drive 26 is sleeved on the guide rod 25, and the blanking drive 26 is located between the workpiece 4 and the mounting member 24; when the guide rod 25 is inserted into the storage chamber 21a, and the storage seat 21 is placed upright, the blanking drive 26 abuts against the side of the workpiece 4 located at the top layer away from the discharge port 21b under the action of its own gravity, so that the blanking drive 26 generates a downward force on the workpiece 4, thereby further reducing the probability of the workpiece 4 getting stuck in the storage chamber 21a.

[0087] In some embodiments, the blanking drive member 26 is a structure including a spring; one end of the blanking drive member 26 abuts against the mounting member 24, and the other end abuts against the side of the topmost workpiece 4 away from the discharge port 21b, and the blanking drive member 26 is in a compressed state to apply a force along the vertical direction X and toward the discharge port 21b to the workpiece 4.

[0088] In some embodiments, the automatic feeding device 1 further includes a sensing member 5 and a control member (not shown in the figure). The sensing member 5 is configured to sense the position of the topmost workpiece 4 in the storage chamber 21a. The sensing member 5 and the conveying assembly 3 are both controlled by the control member. Specifically, the sensing member 5 is a structure including a distance sensor. The sensing member 5 is connected to the mounting member 24, and the sensing end of the sensing member 5 is arranged toward the topmost workpiece 4 in the storage chamber 21a to sense the distance between the corresponding workpiece 4 and the sensing member 5; each time the distance between the topmost workpiece 4 and the sensing member 5 increases, it indicates that the pusher 22 pushes the material once. The control member is a structure including a PLC. Each time the pusher 22 pushes the material once, the control member causes the conveying assembly 3 to operate once, thereby achieving intermittent operation of the conveying assembly 3 at the frequency of the workpiece 4 output from the discharge port 21b, so that the workpiece 4 that falls to the conveying assembly 3 can be automatically and neatly arranged in the conveying assembly 3 to facilitate the subsequent operation of taking the workpiece 4. In the embodiment where the mounting member 24 is omitted, the sensing member 5 is mounted on the upper end of the storage seat 21 so that the sensing member 5 senses the position of the uppermost workpiece 4 in the storage chamber 21 a .

The size of the discharge port 21b along the vertical direction X is greater than the thickness of a single workpiece 4 and less than twice the thickness of a single workpiece 4, so that the discharge port 21b allows one workpiece 4 to pass through each time, so that the workpiece 4 at the bottom layer can be output from the discharge port 21b. A push hole 21d is provided on the outer side wall of the storage seat 21 on the side away from the discharge port 21b, and the push hole 21d is communicated with the storage chamber 21a, and the push hole 21d is aligned with the discharge port 21b.

In some embodiments, the thickness of the push plate 221 is equal to or greater than the thickness of the workpiece 4; when the thickness of the push plate 221 is greater than the thickness of the workpiece 4, a clearance groove can be opened at the bottom wall of the storage chamber 21a, so that the upper surface of the push plate 221 is lower than the upper surface of the lowest workpiece 4 in the storage chamber 21a, so that the push plate 221 only pushes the workpiece 4 at the lowest position.

[0091] In some embodiments, the connecting block 222 can be omitted, and the push plate 221 is directly connected to the push driving member 23, and the push plate 221 is slidably matched with the push hole 21d, so that the push driving member 23 drives the push plate 221 to move.

[0092] In some embodiments, the push drive 23 includes a cylinder, the cylinder body of the push drive 23 is fixedly connected to the storage seat 21, and the piston rod of the push drive 23 is connected to the push member 22 to drive the push member 22 to move back and forth.

In the embodiment containing the conveying component 3, the conveying component 3 is docked with the guide groove 21f to receive and transmit the workpiece 4 that slides out of the guide groove 21f.

Under the action of mutual resistance between adjacent workpieces 4, the workpiece 4 can be automatically arranged in sequence along the length direction of the extension groove 21e, so as to push the workpiece 4 into the guide groove 21f; similarly, the guide groove 21f and the workpiece 4 slide and cooperate, so that the workpiece 4 can be arranged in sequence in the guide groove 21f, and the workpiece 4 can be discharged from the lower end of the guide groove 21f. In some embodiments, the inclined section 212b is inclined upward so that the guide groove 21f is inclined upward relative to the extension groove 21e. In some embodiments, the guide groove 21f is inclined relative to the extension groove 21e in the horizontal direction to change the direction of movement of the workpiece 4.

[0096] The limiting portion 213 is covered on the upper surface of the extension portion 212, and the lower surface of the extension portion 212 is shaped like the upper surface of the extension portion 212, so that the extension portion 212 abuts against the workpiece 4 located in the extension groove 21e and the guide groove 21f, thereby limiting and guiding the workpiece 4, reducing the probability of stacking of the workpiece 4. Magnets 7 are embedded in the upper surface of the extension portion 212 and the lower surface of the limiting portion 213, and the magnets 7 attract each other, so that the limiting portion 213 and the extension portion 212 are stably connected to each other, and the limiting portion 213 is easy to disassemble and assemble. In some embodiments, the extension portion 212 can be omitted, and the effect of stable movement of the workpiece 4 in the extension groove 21e or the guide groove 21f can be achieved by controlling the moving speed of the workpiece 4, that is, controlling the pushing speed of the pusher 22.

[0097] In some embodiments, the extension groove 21e and the guide groove 21f can also be opened on the side wall of the extension portion 212, and the limiting portion 213 is covered on the extension groove 21e and the guide groove 21f; after the extension portion 212 is removed, the stuck workpiece 4 can be removed in the horizontal direction so that the workpiece 4 can slide stably in the extension groove 21e or the guide groove 21f.

[0098] In some embodiments, the workpiece 4 is placed horizontally in the extension groove 21e and the guide groove 21f, that is, the length direction of the workpiece 4 is arranged along the width direction of the extension groove 21e or the guide groove 21f; the width of the extension groove 21e and the guide groove 21f is equal to the length of the workpiece 4 or slightly less than the length of the workpiece 4, so that there is friction between the workpiece 4 and the inner wall of the extension groove 21e or the guide groove 21f, reducing the probability of the workpiece 4 deflecting or tilting in the extension groove 21e or the guide groove 21f, so that the workpiece 4 can be automatically and neatly arranged in the extension groove 21e or the guide groove 21f. In some embodiments, the width of the guide groove 21f is greater than the length of the workpiece 4, so that the workpiece 4 moved from the extension groove 21e to the guide groove 21f can automatically slide out to the designated station along the guide groove 21f.

[0099] Reference Figure 6 and Figure 7 In some embodiments, the blanking assembly 2 further includes an abutment member 27 and an elastic member 28; the abutment member 27 is provided with an inclined guide surface 27a, and the elastic member 28 is configured to provide an elastic force for moving the abutment member 27 toward the workpiece 4, so that the guide surface 27a abuts against a side of the workpiece 4 corresponding to the discharge port 21b that is away from the pusher 22. Further, the moving direction of the abutment member 27 is perpendicular to the moving direction of the pusher 22.

[0100] Further, the abutting member 27 includes an abutting rod 271 and a connecting member 272, the abutting rod 271 is connected to the connecting member 272, and the guide surface 27a is located on the abutting rod 271; the outer wall of the storage seat 21 is provided with a mounting hole 21g, the bottom wall of the mounting hole 21g is provided with a sliding hole 21h communicating with the storage chamber 21a, the connecting member 272 is located in the mounting hole 21g, and the abutting rod 271 and the sliding hole 21h are slidably matched; the storage seat 21 is provided with a blocking member 6 for blocking the mounting hole 21g; the elastic member 28 is located in the mounting hole 21g, and one end of the elastic member 28 abuts against the connecting member 272, and the other end abuts against the blocking member 6. Specifically, the guide surface 27a is an arc surface, and the guide surface 27a is provided on the end wall of the abutting rod 271 away from the connecting member 272. In some embodiments, the connecting member 272 is slidably matched with the mounting hole 21 g to allow the abutment rod 271 to slide relative to the storage seat 21 .

[0101] Specifically, the mounting hole 21g is a circular hole, and the inner wall of the mounting hole 21g away from the sliding hole 21h is provided with an internal thread; the sliding hole 21h is a rectangular hole. The blocking member 6 is cylindrical, and the peripheral wall of the blocking member 6 is provided with an external thread, and the blocking member 6 is threadedly connected to the inner wall of the mounting hole 21g away from the sliding hole 21h to block the mounting hole 21g. The elastic member 28 includes a spring, and the elastic member 28 is in a compressed state, so that the elastic member 28 has an elastic force toward the direction of the workpiece 4 on the abutment rod 271 through the connecting member 272, so that the guide surface 27a and the workpiece 4 can be kept in abutment; in the process of the pusher 22 pushing the workpiece 4, the corresponding workpiece 4 and the pusher 22 can always be kept in abutment through the friction between the guide surface 27a and the workpiece 4, which is conducive to keeping the state of the workpiece 4 constant and reducing the probability of the workpiece 4 being skewed and causing the workpiece 4 to be stuck. In some embodiments, the blocking member 6 is plate-shaped, and is fixed to the outer wall of the storage seat 21 by screws so that the blocking member 6 blocks the installation hole 21g.

[0102] When the pushing member 22 pushes the workpiece 4, under the action of the guide surface 27a, the abutment rod 271 moves toward the blocking member 6, so that the guide surface 27a abuts against the side wall of the workpiece 4 on the side close to the sliding hole 21h, thereby allowing the workpiece 4 to continue to move toward the discharge port 21b; when the workpiece 4 moves to the point where the guide surface 27a abuts against the side of the workpiece 4 close to the pushing member 22, the pushing member 22 retreats, and the abutment rod 271 moves away from the blocking member 6, so that the abutment rod 271 abuts against the next workpiece 4 to be pushed by the pushing member 22.

[0103] The automatic feeding device 1 provided in the present application drives the pushing member 22 to move through the pushing driving member 23, so that the pushing member 22 pushes the workpieces 4 located in the storage chamber 21a out of the discharge port 21b one by one, thereby realizing automatic feeding of the workpieces 4; compared with using a vibration plate or other feeding mechanisms, the automatic feeding device 1 provided in the present application has a simple structure and lower cost.

[0104] The above are only specific implementation methods of the present application, but the protection scope of the present application is not limited thereto, and any changes or substitutions within the technical scope disclosed in the present application should be included in the disclosure scope of the present application.
