DETAILED DESCRIPTION

[0050] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the present invention will be briefly introduced below in combination with the drawings and the descriptions of the embodiments or the prior art. Obviously, the following descriptions of the structures of the drawings are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0051] The technical solution provided by the present invention will be described in detail below by way of embodiments with reference to the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0052] In some instances, some embodiments are not described or not described in detail because they belong to existing or conventional technologies.

[0053] In addition, the technical features recorded in this article, or the steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can also be combined in any suitable manner in one or more embodiments. For those skilled in the art, it is easy to understand that the steps or operation sequence of the methods related to the embodiments provided herein can also be changed. Any order in the drawings and embodiments is only for illustrative purposes and does not imply a requirement to follow a certain order unless it is explicitly stated that a certain order is required.

[0054] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, under reasonable circumstances (not constituting a self-contradiction), include direct and indirect connections (couplings).

[0055] Reference Figures 1 to 8 The material supply device of this embodiment includes:

[0056] The conveying part 1 has one end as a feeding end and the other end as a discharging end. The conveying part 1 is provided with a material trough 11 extending from the feeding end to the discharging end, and a material drop opening 12 is provided on the side wall of the material trough 11.

[0057] A direct vibration feeder 2, detachably connected to the conveying part 1;

[0058] The directional alignment part 3 is detachably connected to the conveying part 1 and is used for directional alignment and screening of the materials in the material trough 11 . Qualified materials continue to be conveyed along the material trough 11 , and unqualified materials are discharged through the discharge port 12 .

[0059] The direct vibration feeder 2 is a prior art, and the finished product can be directly purchased, so it will not be described in detail here.

[0060] The specific structure of the directional aligning part 3 is matched according to the specific material. Technical personnel in this field can also easily derive some specific structures of the directional aligning part 3 for screening specific materials in a limited number of experiments based on the screening structure of the spiral flow channel of the vibrating disk combined with the common knowledge and technical principles in this field. Moreover, the improvement of the present invention lies in the creative combination of the straight vibration feeder 2 with different conveying parts 1 and the directional aligning part 3 to complete the supply of different materials, rather than the specific structure of the directional aligning part 3. Therefore, the specific structure of the directional sorting part is not limited here.

[0061] In an optional embodiment of the material supply device of the present disclosure, the material supply device may further include:

[0062] The recovery conveyor 4 is used to convey the materials discharged from the drop port 12 to the feeding end of the conveying part 1 .

[0063] In this embodiment, the recovery conveyor 4 and the straight vibration feeder 2 are both fixed to the frame 9 .

[0064] The recovery conveyor 4 can be implemented by existing technologies such as a belt conveyor. In an optional embodiment of the material supply device disclosed in the present invention, the recovery conveyor 4 may include:

[0065] The belt conveyor 41 gradually tilts upward from the discharge end to the feed end, and the lower end of the belt conveyor 41 is connected to the drop port 12, and the upper end of the belt conveyor 41 is connected to the feed end. The belt conveyor 41 is tilted, which is conducive to the material falling freely into the lower end of the belt conveyor 41 directly by its gravity without adding an additional conveying mechanism, which is conducive to structural simplification and cost reduction. In this embodiment, the material falling out of the drop port 12 is guided to the lower end of the belt conveyor 41 by the material receiving sheet metal 42. Specifically, the material receiving sheet metal 42 is in a U-shape with an opening facing upward, and the upper end of the material receiving sheet metal 42 is located directly below the drop port 12, and the lower end of the material receiving sheet metal 42 is located directly above the lower end of the belt conveyor 41, so that the material slides into the belt conveyor 41 under the action of its own gravity. On one hand, the belt conveyor 41 can recover the materials dropped from the material drop port 12; on the other hand, it can also add materials into the material trough 11 at the beginning. Specifically, in this embodiment, baffles are fixed at the bottom and both sides of the belt conveyor 41 to prevent material leakage.

[0066] The upper end of the belt conveyor 41 can transfer the material to the material trough 11 at the feeding end in a manner similar to the above-mentioned material receiving sheet metal 42, or can transfer the material to the material trough 11 at the feeding end in a conveyor manner. In an optional embodiment of the material supply device disclosed in the present invention, the recovery conveyor 4 may also include:

[0067] The material tray 43 has a material inlet at one end and a material outlet at the other end, and the material outlet is located just above the material inlet end;

[0068] A straight feeder 44 is detachably connected below the feed tray 43;

[0069] A hopper 45 is located directly above the feed inlet;

[0070] The material receiving body 46 is in a U-shape with its opening facing upwards. One end of the material receiving body 46 is located directly above the hopper 45 , and the other end of the material receiving body 46 is located directly below the upper end of the belt conveyor 41 .

[0071] The straight feeder 44 is fixed to the frame 9 .

[0072] The belt conveyor 41 conveys the materials falling out of the material dropout port 12 and the artificially added materials to the upper end of the belt conveyor 41, and the materials fall into the material receiving body 46 under the action of their own weight. The materials in the material receiving body 46 fall into the inlet of the material tray 43 through the hopper 45 under the action of their own gravity. Under the vibration of the straight feeder 44, the materials at the inlet are conveyed to the outlet, and fall into the material trough 11 at the inlet end under the action of the material's own gravity. It should be noted that the straight feeder 44, i.e., the straight vibration feeder 2, is a prior art, and the finished product can be directly purchased, so it will not be described in detail here.

[0073] In an optional embodiment of the material supply device disclosed herein, the upper portions of the two side walls of the material trough 11 at the feed end are formed into a trumpet shape that is larger at the top and smaller at the bottom, thereby guiding the material. In the process of the material falling from the material tray 43 into the material trough 11, the risk of the material falling out of the material trough 11 is greatly reduced.

[0074] In an optional embodiment of the material supply device disclosed in the present invention, the bottom surface of the material trough 11 is inclined relative to the horizontal plane, and the side wall located on the high side of the bottom of the material trough 11 is provided with the drop opening 12, and the drop opening 12 is opened to the bottom surface of the material trough 11. By setting the inclined bottom surface of the trough, the material moves toward the low side of the bottom of the trough under its own gravity, thereby reducing the amount of material with the correct posture falling out of the drop opening 12.

[0075] In an optional embodiment of the material supply device of the present disclosure, a dislocation mechanism 5 may be further included, and the dislocation mechanism 5 may include:

[0076] The docking portion 51 is provided with a docking groove 5111 for docking with the material discharging end. The docking portion 51 has an original position and a moving position. The docking portion 51 slides back and forth between the original position and the moving position. The sliding direction of the docking portion 51 is perpendicular to the opening direction of the material slot 11.

[0077] The material blocking body 52 is fixed to one side of the docking portion 51 close to the origin;

[0078] The linear motion driving unit 53 drives the docking portion 51 to slide back and forth.

[0079] By providing the misalignment mechanism 5, a whole row of materials can be misaligned into individual materials, making it convenient for other mechanisms to grab the materials.

[0080] When the docking portion 51 leaves the material discharging end, the material blocking body 52 is used to block the opening of the material trough 11 to prevent the material from falling.

[0081] The linear motion drive unit 53 can be implemented by using existing technologies such as a crank slider mechanism, an electric cylinder, and a single-axis robot. In this embodiment, the linear motion drive unit 53 is implemented by using a pneumatic slide, which can be purchased as a finished product and will not be described in detail. The linear motion drive unit 53 is fixed to the frame 9.

[0082] In an optional embodiment of the material supply device of the present disclosure, the material supply device may further include:

[0083] The material channel 6 is arranged in parallel with the conveying part 1, and the material channel 6 is provided with a through conveying groove 61, and the opening direction of the conveying groove 61 is parallel to the opening direction of the material trough 11, and one end of the conveying groove 61 is connected with the docking part 51 at the moving point;

[0084] A linear vibrating feeder 7 is connected to the material channel 6;

[0085] The material-dispensing mechanism 8 conveys the material in the docking groove 5111 of the docking portion 51 at the moving point to the conveying groove 61 .

[0086] The linear vibration feeder 7, namely the straight vibration feeder 2, is a prior art and can be directly purchased as a finished product, so it will not be described in detail here.

[0087] By setting a material channel 6 parallel to the conveying part 1 and setting a material-dispensing mechanism 8, the material in the docking groove 5111 is transferred to the conveying groove 61. Since the conveying groove 61 delivers the material from the end away from the lower end of the belt conveyor 41, that is, the end of the material supply device docking with other mechanisms is away from the lower end of the belt conveyor 41, that is, away from the end of manual feeding, the manual activity space is increased, and it is convenient to add materials to the belt conveyor 41.

[0088] The linear vibrating feeder 7 is fixed to the frame 9.

[0089] In an optional embodiment of the material supply device of the present disclosure, the docking portion 51 may include:

[0090] The docking body 511 is provided with the docking groove 5111;

[0091] The rotary motion driving unit drives the docking body 511 to rotate back and forth. The rotation axis of the docking body 511 is parallel to the opening direction of the docking groove 5111 . The rotary motion driving unit is connected to the linear motion driving unit 53 .

[0092] By setting a rotary motion drive unit to drive the docking body 511 to rotate, the height of the docking groove 5111 can be changed, that is, the docking height of the conveying groove 61 can be changed, so that there is a height difference between the material channel 6 and the conveying part 1, which is convenient for the installation of other components between the material channel 6 and the conveying part 1.

[0093] The rotary motion drive unit can be implemented by existing technologies such as gear rack mechanism, motor, pneumatic motor, etc. In the present embodiment, the rotary motion drive unit includes a bracket 516 fixed to the pneumatic slide, a servo motor 512 fixed to the bracket 516, an active bevel gear 513 fixed to the output end of the servo motor 512, a driven bevel gear 514 meshing with the active bevel gear 513, and a rotating shaft 515 rotatably supported on the bracket 516; the rotation axis of the rotating shaft 515 is parallel to the opening direction of the material trough 11 and perpendicular to the sliding direction of the docking part 51; the driven bevel gear 514 and the docking body 511 are both fixedly connected to the rotating shaft 515.

[0094] In an optional embodiment of the material supply device disclosed in the present invention, the material feeding mechanism 8 may include:

[0095] The material-moving rod 81 is arranged to slide back and forth along the opening direction of the conveying groove 61;

[0096] A linear driving member 83 drives the material moving rod 81 to slide back and forth;

[0097] The side wall of the docking groove 5111 and the side wall of the conveying groove 61 are both provided with an avoidance groove for avoiding the material removing rod 81 .

[0098] The linear drive member 83 can be realized by using existing technologies such as oil cylinders. In this embodiment, the linear drive member 83 is realized by using a cylinder. Specifically, the cylinder body of the cylinder is fixed to the frame 9, and the piston rod of the cylinder is fixedly connected to the material-moving rod 81. In order to guide the movement direction of the material-moving rod 81, in this embodiment, a linear rolling guide 82 is provided between the material-moving rod 81 and the frame 9. Specifically, the guide rail of the linear rolling guide 82 is fixed to the frame 9, and the slider of the linear rolling guide 82 is fixedly connected to the material-moving rod 81.

[0099] The present invention is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present invention.
