[0024] Please refer to Figure 1 and Figure 2 , the embodiment of the present application provides a feeding device 100 for automatically providing workpieces 200, which can be block-shaped, plate-shaped or the like. The feeding device 100 comprises a bearing plate 10, a pushing assembly 30 and a supporting assembly 40.

[0025] Specifically, please refer to Figure 1 , Figure 2 and Figure 3 , the bearing plate 10 can be plate-shaped, and the lower side of the bearing plate 10 can be provided with a supporting leg 11 or the like to support the bearing plate 10.

[0026] The hopper 20 is connected to the bearing plate 10, and a discharge port 21 extending along the X-axis direction is arranged between the hopper 20 and the bearing plate 10. The hopper 20 is used to accommodate workpieces 200 stacked along the Z-axis direction, and the lower end of the hopper 20 is provided with a discharging port 22 communicating with the discharge port 21, so that the lowermost workpiece 200 in the hopper 20 can be moved to the discharge port 21.

[0027] The pushing assembly 30 comprises a driving member 31 connected to the bearing plate 10 and a pushing member 32 connected to the driving member 31. The pushing member 32 is slidingly arranged in the discharge port 21, and is provided with a first inclined surface 321. The driving member 31 can be a driving device such as a pneumatic cylinder, and the pushing member 32 can be plate-shaped. In this embodiment, the pushing member 32 is substantially isosceles trapezoidal, with the lower base used to push the workpiece 200 and the first inclined surface 321 being the waist of the pushing member 32. It can be understood that, in order to save space, the driving member 31 can be arranged on the side of the bearing plate 10 away from the hopper 20, and when the driving member 31 drives the pushing member 32 to move, the pushing member 32 does not extend outward beyond the bearing plate 10.

The supporting assembly 40 comprises a supporting member 41 and a resilient member 42. The supporting member 41 can slide along the Y-axis direction to the discharge port 21 and move to the lower side of the discharging port 22. The side of the supporting member 41 facing the discharge port 21 is provided with a second inclined surface 411 matching the first inclined surface 321, and the resilient member 42 is arranged on the side of the supporting member 41 away from the discharge port 21 and used to push the supporting member 41 to slide toward the discharge port 21. The supporting member 41 can be plate-shaped, and in this embodiment, the supporting member 41 is substantially right-angled trapezoidal, with the second inclined surface 411 being the waist of the supporting member 41, and the plane on which the second inclined surface 411 lies being parallel to the plane on which the first inclined surface 321 lies. The resilient member 42 can be a spring or the like. In order to improve the stability of the resilient member 42 in pushing the movement of the supporting member 41, the resilient member 42 can be provided with multiple, such as two, three or the like, resilient members 42, each arranged on the side of the supporting member 41 away from the discharge port 21.

[0029] The driving member 31 is configured to drive the pushing member 32 to move along the X-axis direction to move the lowermost workpiece 200 out of the discharge port 21, and the supporting member 41 is configured to move to the lower side of the discharge port 33 under the pushing of the elastic member 42 to support the workpiece 200 in the material bin 20. The driving member 31 is further configured to drive the pushing member 32 to move in the opposite direction of the X-axis direction, so that the first inclined surface 321 on the pushing member 32 pushes the second inclined surface 411 on the supporting member 41 to move the supporting member 41 away from the discharge port 21, and then the lowermost workpiece 200 in the material bin 20 falls into the discharge port 21.

[0030] In the embodiment, in order to improve the stability of the supporting member 41 when supporting the workpiece 200, two sets of supporting assemblies 40 can be arranged, and the two sets of supporting assemblies 40 are symmetrically arranged on both sides of the material bin 20 along the Y-axis direction. The first inclined surface 321 on the pushing member 32 is provided with two first inclined surfaces 321, and the two first inclined surfaces 321 are respectively arranged corresponding to the second inclined surfaces 411 of the two supporting members 41. In this way, when the pushing member 32 pushes the workpiece 200, the two ends of the lowermost workpiece 200 in the material bin 20 can be supported by the two supporting members 41, so as to improve the stability of the support.

[0031] In the embodiment, a plurality of sets of material bins 20, pushing assemblies 30 and supporting assemblies 40, such as two sets, four sets, six sets, etc., can be arranged on the bearing plate 10 to simultaneously supply materials and improve the material supply speed. The plurality of sets of material bins 20, pushing assemblies 30 and supporting assemblies 40 can be arranged on the bearing plate 10 in a symmetrical manner or a parallel manner, and the specific number and position can be arranged according to actual production requirements, which is not limited herein.

[0032] The material supply device 100 provided by the embodiment of the present application is arranged with the workpieces 200 stacked in the material bin 20, and the workpieces 200 can move to the discharge port 21 below the material bin 20 by the gravity of the workpieces 200 themselves. The driving member 31 in the pushing assembly 30 can drive the pushing member 32 to push the workpiece 200 located in the discharge port 21 to move out of the discharge port 21. The elastic member 42 of the supporting assembly 40 can push the supporting member 41 to move to the discharge port 21 during the movement of the pushing member 32 out of the discharge port 21, so that the supporting member 41 can support other workpieces 200 in the material bin 20. When the driving member 31 drives the pushing member 32 to move to the discharge port 21, the pushing member 32 can push the supporting member 41 away from the discharge port 21, so that the workpieces 200 in the material bin 20 can move to the discharge port 21 for the next pushing. The above-mentioned material supply device 100 can automatically supply materials, and the pushing member 32 does not need to extend out of the bearing plate 10. The supporting member 41 can support the workpieces 200 in the material bin 20 during the pushing process, which reduces the space occupied by the material supply device 100 and is beneficial to improve the space utilization rate of the machining workshop.

[0033] In some embodiments, please refer toFigure 2 、 Figure 3 and Figure 4 The support assembly 40 further comprises a base 43, a cover plate 44 and a back cover 45. The base 43 is connected to the bearing plate 10 and is arranged close to the hopper 20 along the Y-axis direction. The base 43 is provided with a movable groove 431 extending along the Y-axis direction and communicating with the discharge port 21. The cover plate 44 is arranged on the side of the base 43 away from the bearing plate 10 and covers the movable groove 431. The back cover 45 is connected to the side of the base 43 away from the discharge port 21. The support piece 41 is slidingly arranged in the movable groove 431. The elastic piece 42 is arranged in the movable groove 431, and the two ends of the elastic piece 42 abut against the support piece 41 and the back cover 45, respectively. The base 43 is generally plate-shaped to support the support piece 41. The movable groove 431 provided in the base 43 allows the support piece 41 to move along the Y-axis direction. The cover plate 44 can be plate-shaped. By arranging the cover plate 44, the support piece 41 can be limited in the Z-axis direction to avoid deviation of the support piece 41 in the Z-axis direction, which causes the support piece 41 to be unable to move to the lower side of the workpiece 200. The back cover 45 can be block-shaped or plate-shaped. By arranging the back cover 45, the elastic piece 42 can be supported to push the support piece 41 to move towards the discharge port 21. It can be understood that the back cover 45 is detachably connected to the base 43, which facilitates inspection and replacement of the support piece 41 and the elastic piece 42.

[0034] In some embodiments, referring to Figure 4 The support piece 41 is provided with a strip-shaped hole 412 arranged along the Y-axis direction. The support assembly 40 further comprises a limiting pin 46 connected to the cover plate 44 and inserted into the strip-shaped hole 412. The limiting pin 46 cooperates with the strip-shaped hole 412 to limit the distance of movement of the support piece 41 along the Y-axis direction. In this way, by cooperation of the limiting pin 46 and the strip-shaped hole 412 on the support piece 41, the support piece 41 can be prevented from being pushed out of the movable groove 431 by the elastic piece 42.

[0035] In some embodiments, referring to Figure 4 The support assembly 40 further comprises a plurality of rolling pieces 47. The plurality of rolling pieces 47 are each rotatably connected to the base 43 and arranged on the two sides of the movable groove 431 along the X-axis direction. Each rolling piece 47 abuts against the side wall of the support piece 41 along the X-axis direction. The rolling piece 47 can be a bearing, and the number of rolling pieces 47 can be eight, ten, twelve, etc. The rolling pieces 47 can be arranged in two groups, respectively opposite to the side walls of the support piece along the X-axis direction. The number of rolling pieces 47 in each group can be four, five, six, etc. By arranging the rolling pieces 47, the friction between the support piece 41 and the groove wall of the movable groove 431 can be reduced, the service life of the support piece 41 can be improved, and the smoothness of movement of the support piece 41 in the movable groove 431 can be improved.

[0036] In some embodiments, referring toFigure 4 The base 43 is further provided with a plurality of sliding grooves 432 extending along the Y-axis direction, and the plurality of sliding grooves 432 are arranged at the bottom of the movable groove 431 and communicate with the movable groove 431. The support piece 41 is provided with a plurality of protruding portions 413 extending along the Y-axis direction on the side of the bottom of the movable groove 431, and the plurality of protruding portions 413 correspond to the plurality of sliding grooves 432 and are slidingly arranged in the corresponding sliding grooves 432. The plurality of protruding portions 413 cooperate with the plurality of sliding grooves 432 to limit the movement direction of the support piece 41. In this way, the cooperation of the protruding portions 413 and the sliding grooves 432 can further limit the movement direction of the support piece 41, which is beneficial to further improve the accuracy of the movement of the support piece 41.

[0037] In some embodiments, referring to Figure 2 and Figure 3 The pushing piece 32 is provided with a profiling groove 322 on the side for pushing the workpiece 200, and the profiling groove 322 is matched with the structure of the workpiece 200 to limit the workpiece 200 when the pushing piece 32 pushes the workpiece 200. It can be understood that the structure of the profiling groove 322 is matched with the structure of the workpiece 200, for example, the side opposite to the pushing piece 32 of the workpiece 200 is arc-shaped, and the structure of the profiling groove 322 is corresponding arc-shaped, the side opposite to the pushing piece 32 of the workpiece 200 is straight, and the bottom of the profiling groove 322 is corresponding line, and the specific structure of the profiling groove 322 is consistent with the structure of the workpiece 200, which is not limited here.

[0038] In some embodiments, referring to Figure 2 , Figure 3 and Figure 4 The maximum distance between the support piece 41 and the bearing plate 10 along the Z-axis direction is less than the thickness of the workpiece 200 along the Z-axis direction, and greater than the maximum distance between the pushing piece 32 and the bearing plate 10 along the Z-axis direction, so that the pushing piece 32 can move to the lower side of the workpiece 200 in the hopper 20 when the pushing piece 32 pushes the workpiece 200 out of the discharge port 21, and the pushing piece 32 can move to the discharge port 21. In this way, when the pushing piece 32 pushes the lowermost workpiece 200 to move out of the discharge port 21, the support piece 41 moves towards the discharge port 21 and can extend to the second-to-last workpiece 200, and when the pushing piece 32 pushes the lowermost workpiece 200 to move out of the discharge port 21, the support piece 41 can support the workpiece 200 in the hopper 20. When the pushing piece 32 moves towards the discharge port 21, the pushing piece 32 can move below the workpiece 200 supported by the support piece 41, and then push the support piece 41 away from the discharge port 21 until the pushing piece 32 pushes the support piece 41 away from the lower side of the workpiece 200, so that the workpiece 200 falls into the discharge port 21.

[0039] In some embodiments, referring to Figure 2 and Figure 3The bearing plate 10 is provided with a position-avoiding groove 12 arranged along the X-axis direction. The pushing assembly 30 further comprises a connecting piece 33. The driving part is arranged on the side of the bearing plate 10 away from the material bin 20. The connecting piece 33 is slidingly arranged in the position-avoiding groove 12, and the connecting piece 33 is connected with the driving part 31 and the pushing piece 32 respectively. The connecting piece 33 can be a special-shaped mechanism. The driving part 31 is arranged on the side of the bearing part away from the material bin 20, so that the space can be effectively utilized. The position-avoiding groove 12 is arranged, so that the connecting piece 33 can be avoided when the driving part 31 drives the pushing piece 32 to move along the X-axis direction. Thus, the connecting piece 33 can move in the space occupied by the bearing plate 10 to drive the pushing piece 32 to move, so that the space occupied by the feeding device 100 can be further saved.

[0040] In the embodiment, the pushing piece 32 is arranged spaced apart from the bearing plate 10 along the Z-axis direction. It can be understood that the connecting piece 33 can be arranged above the bearing plate 10 to make the pushing piece 32 not in contact with the bearing plate 10, so as to reduce the friction between the pushing piece 32 and the bearing plate 10 and improve the service life of the pushing piece 32.

[0041] In some embodiments, referring to Figure 2 and Figure 3 The side of the bearing plate 10 for bearing the workpiece 200 is further provided with a limiting groove 13 arranged along the movement path of the pushing piece 32. The width of the limiting groove 13 along the Y-axis direction is matched with the length of the workpiece 200 along the Y-axis direction. The limiting groove 13 is used for limiting the workpiece 200 in the Y-axis direction when the pushing piece 32 pushes the workpiece 200 to move. The limiting groove 13 can improve the stability of the workpiece 200 in the Y-axis direction when the pushing piece 32 pushes the workpiece 200 to move.

[0042] In some embodiments, referring to Figure 2 and Figure 3 The bearing plate 10 is further provided with a positioning piece 14 arranged in the limiting groove 13. The positioning piece 14 is used for stopping the workpiece 200 moved by the pushing piece 32 along the X-axis direction, so as to position the workpiece 200. The positioning piece 14 can be a columnar structure. The positioning piece 14 can stop the workpiece 200 after the pushing piece 32 moves the workpiece 200 from the discharge port 21 to the preset position, so as to position the workpiece 200 and facilitate the external material taking device (not shown) to take the material.

[0043] The working process of the feeding device 100 provided by the embodiment is as follows:

[0044] Firstly, a plurality of workpieces 200 are placed in the hopper 20 in a stacked manner, and the lowermost workpiece 200 is moved from the discharge port 22 of the hopper 20 to abut against the carrier plate 10, at this time, the lowermost workpiece 200 is located at the discharge port 21. Then the driving member 31 drives the pushing member 32 to move along the X-axis direction, and then pushes the workpiece 200 located at the discharge port 21 to move along the X-axis direction. At the same time, the elastic member 42 pushes the supporting member 41 to move into the discharge port 21, and before the pushing member 32 pushes the lowermost workpiece 200 to separate from the second lowermost workpiece 200, the supporting member 41 moves into the discharge port 21 to support the remaining workpieces 200 in the hopper 20. The pushing member 32 continues to move along the X-axis direction, and then pushes the workpiece 200 to the preset position.

[0045] When resetting, the driving member 31 drives the pushing member 32 to move along the reverse direction of the X-axis direction, and then moves the pushing member 32 into the discharge port 21, when the pushing member 32 abuts against the supporting member 41, the first inclined surface 321 pushes the second inclined surface 411, and then the supporting member 41 moves away from the discharge port 21, until the supporting member 41 moves away from the workpiece 200, at this time, the pushing member 32 also moves away from the discharge port 22, the pushing member 32 still abuts against the supporting member 41, and the workpiece 200 falls into the discharge port 21 from the discharge port 22. Then the pushing member 32 moves along the X-axis direction again, and the above discharge step is repeated.
