Description

Technical Field

[0001] The utility model relates to the technical field of automatic feeding, in particular to an automatic feeding device. Background Art

[0002] In the field of parts material processing, automatic loading devices are often used to achieve automatic loading in order to reduce labor intensity and improve work efficiency.

[0003] The Chinese utility model patent with the announcement number CN218464804U discloses an automatic arrangement conveying device, in which a conveying member conveys multiple workpieces in a predetermined direction, and guides the multiple workpieces on the conveying member through a guide assembly, and then a push mechanism pushes the guided workpiece to move to a first position, and finally a pull mechanism receives the workpiece at the first position and pushes the workpiece to move to an output position. In this way, the workpiece on the conveying member is guided by the guide assembly so that the workpiece maintains a preset direction and a preset spacing, and the push mechanism and the pull mechanism cooperate to realize the rapid output of the workpiece to the output position, and the workpieces output by the push mechanism and the pull mechanism are neatly arranged and accurately positioned, which is convenient for subsequent devices such as manipulators to grab, thereby improving the conveying efficiency.

[0004] The defect of the prior art is that a row of workpieces conveyed by the conveyor moves forward until they are in place. After the first row of workpieces is in place, they are grabbed by the robot, and then each workpiece in the first row is moved to the processing equipment of the next process. Since the first row of workpieces at the front end includes multiple workpieces, the robot needs to move horizontally to grab one workpiece at a time, which places high requirements on the robot. It is necessary to locate the station of each workpiece arranged horizontally at the front end of the conveyor device, and the robot needs to move horizontally one by one to pick up multiple workpieces in the first row in sequence. The robot needs to swing multiple times, and the control method is complicated. If there is a deviation when the robot swings, it is difficult to pick up the workpiece, and the probability of failure is high. Utility Model Content

[0005] The utility model aims to overcome the deficiencies of the prior art and provides a novel automatic loading device, wherein a laterally slidable linear guide rail is arranged on one side of a loading pallet, and a guide rail driving mechanism is used to drive the linear guide rail to cooperate with and separate from the loading pallet. When the guide rail driving mechanism drives the linear guide rail to cooperate with the loading pallet, the first push plate mechanism pushes the material toward the linear guide rail, and the linear guide rail carries a row of materials, and then the guide rail driving mechanism separates the linear guide rail from the loading pallet, so that the linear guide rail carries a row of materials and separates the materials on the loading pallet, and then the second push plate mechanism pushes a row of materials in the linear guide rail forward, so that the row of materials enters the discharging rack at the front end one by one, and the manipulator mechanism picks up the materials from the discharging rack to the loading platform each time. During the picking process, the manipulator mechanism only needs to move up and down, and does not need to swing horizontally, which is convenient for picking up materials, improves work efficiency, and reduces operation difficulty and the probability of failure.

[0050] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings. The same parts are represented by the same figure numbers. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0051] like Figure 1-3 , Figure 5-6 , Figure 8-9 and Fig.12 As shown, an automatic loading device provided by an embodiment of the utility model includes a bracket 1, a loading plate 2, a linear guide rail 3, a loading platform 4, a first pushing plate mechanism 5, a second pushing plate mechanism 6 and a manipulator mechanism 7.

[0052] The material loading pallet 2 is arranged on the bracket 1, and the linear guide rail 3 is slidably arranged on one side of the material loading pallet 2. The bracket 1 is provided with a guide rail driving mechanism 8 for driving the linear guide rail 3 to cooperate with and separate from the material loading pallet 2.

[0053] The front end of the linear guide rail 3 is provided with a discharging frame 33 with a top opening. The loading platform 4 is connected to the bracket 1 and is located at the front side of the discharging frame 33.

[0054] The first push plate mechanism 5 is connected to the bracket 1 and cooperates with the material loading pallet 2 . The first push plate mechanism 5 is used to push the multiple rows of materials 10 on the material loading pallet 2 toward the linear guide rail 3 in sequence.

[0055] The second push plate mechanism 6 is connected to the bracket 1 and cooperates with the linear guide rail 3 . The second push plate mechanism 6 is used to push a row of materials 10 on the linear guide rail 3 into the discharge rack 33 in sequence.

[0056] The manipulator mechanism 7 is connected to the bracket 1 and can cooperate with the discharge rack 33 and the loading platform 4 . The manipulator mechanism 7 is used to pick up a material 10 in the discharge rack 33 and put it on the loading platform 4 .

[0057] The automatic feeding device provided by the utility model is used for carrying materials 10, and the materials 10 are in block shape.

[0058] The automatic loading device comprises a bracket 1, a loading support plate 2, a linear guide rail 3, a loading platform 4, a first push plate mechanism 5, a second push plate mechanism 6, a manipulator mechanism 7 and a guide rail driving mechanism 8.

[0059] The material loading pallet 2 is a square pallet, which is fixedly mounted on the bracket 1 . The material loading pallet 2 is used to carry multiple rows, columns, and layers of materials 10 .

[0060] The linear guide 3 is located on one side of the loading pallet 2, and the linear guide 3 is used to carry or transport a row of materials 10. The direction in which the linear guide 3 extends is called the front-to-back direction, and the linear guide 3 is located on the left or right side of the loading pallet 2. A plurality of materials 10 arranged along the front-to-back direction are called a row of materials 10, and a plurality of materials 10 arranged along the left-to-right direction are called a row of materials 10. The linear guide 3 can slide laterally or left-to-right on one side of the loading pallet 2. The linear guide 3 and the bracket 1 can be connected by a slide rail. The guide rail drive mechanism 8 is connected between the bracket 1 and the linear guide 3, and is used to drive the linear guide 3 to move back and forth in a straight line. When the linear guide 3 is in the initial state, the linear guide 3 and the loading pallet 2 are separated by a certain distance. Under the action of the guide rail drive mechanism 8, the linear guide 3 can be brought into contact and cooperate with the loading pallet 2 to carry a row of materials on the loading pallet 2. Then, the guide rail driving mechanism 8 acts to separate the linear guide rail 3 from the material carrying plate 2, so that a row of materials on the linear guide rail 3 is separated from the materials on the material carrying plate 2 without affecting each other. The guide rail driving mechanism 8 can be a linear driving mechanism such as a cylinder, an oil cylinder, a motor screw, etc.

[0061] The first push plate mechanism 5 is connected to the bracket 1, and moves horizontally on the material carrying plate 2 or moves toward the linear guide rail 3 to push the multiple columns of materials 10 on the material carrying plate 2 toward the linear guide rail 3. When the column of materials 10 closest to the linear guide rail 3 enters the linear guide rail 3, the first push plate mechanism 5 stops pushing, and when the next column of materials 10 needs to be pushed, the first push plate mechanism 5 pushes again. After completely pushing the materials 10 on the material carrying plate 2, the first push plate mechanism 5 is reset.

[0062] The first push plate mechanism 5 can be any electric push plate mechanism that can push the material 10 on the material carrying plate 2 to move horizontally.

[0063] The front end of the linear guide rail 3 is provided with a discharge rack 33 , and the top of the discharge rack has an opening for the pick-up end of the manipulator mechanism 7 to enter and exit to clamp the material 10 .

[0064] The second push plate mechanism 6 is connected to the bracket 1 and is used to push a row of materials 10 in the linear guide rail 3 forward so that the row of materials 10 enter the front discharge rack 33 one by one. The first push plate mechanism 5 can select any electric push plate mechanism that can push the materials 10 in the linear guide rail 3 forward.

[0065] The second push plate mechanism 6 pushes one material 10 or a group of stacked materials 10 into the discharging rack 33 at a time. After the last material 10 or the last group of stacked materials 10 in all the linear guides 3 are pushed into the discharging rack 33, the second push plate mechanism 6 is reset.

[0066] The loading platform 4 is connected to the bracket 1, and the loading platform 4 is located in front of the unloading rack 33. The loading platform 4 is in the shape of an elongated strip, and extends in the front-to-back direction. Preferably, the loading platform 4 is connected to the front side of the bracket 1, and is located directly in front of the unloading rack 33. Preferably, the linear guide rail 3 is connected to the top surface of the bracket 1, and the loading platform 4 is connected to the front side of the bracket 1. The loading platform 4 is lower than the linear guide rail 3, and in the front-to-back direction, the loading platform 4 is aligned with the unloading rack 33. The loading platform 4 is used to position the material 10 to be loaded, so that the robot of the next process can pick it up, or directly supply it to the next process.

[0067] The manipulator mechanism 7 is connected to the bracket 1, and can pick up the material 10 from the discharge rack 33, and then place the material 10 on the loading platform 4. The manipulator mechanism 7 can select any pick-up-and-place mechanism that can pick up and put down the material.

[0068] The manipulator mechanism 7 picks up a piece of material 10 or a group of stacked materials 10 from the discharging rack 33 each time. During the picking process, the manipulator mechanism 7 only needs to move up and down without lateral swing, which is convenient for picking up materials 10, improves work efficiency, and reduces operation difficulty and the probability of failure.

[0069] The first push plate mechanism 5, the second push plate mechanism 6, the manipulator mechanism 7 and the guide rail driving mechanism 8 are connected to the control system signal of the automatic feeding device, and the control system controls the automatic operation of the first push plate mechanism 5, the second push plate mechanism 6, the manipulator mechanism 7 and the guide rail driving mechanism 8.

[0070] In one embodiment, if Figure 5-6 and Figure 8-9 As shown, the linear guide rail 3 includes a guide rail upright plate 31 and a guide rail bottom plate 32 connected to the lower end of the guide rail upright plate 31 and extending toward the side of the material loading support plate 2.

[0071] The guide rail driving mechanism 8 is connected to the guide rail vertical plate 31 and / or the guide rail bottom plate 32 .

[0072] When the guide rail driving mechanism 8 is in an initial state, a preset distance is spaced between the guide rail bottom plate 32 and the material loading support plate 2 .

[0073] In this embodiment, the linear guide rail 3 is L-shaped, and includes a guide rail base plate 32 and a guide rail vertical plate 31. The guide rail vertical plate 31 extends vertically, and the guide rail base plate 32 extends toward the side of the loading pallet 2 to receive a column of materials 10 pushed from the loading pallet 2.

[0074] The guide rail bottom plate 32 is slidably connected to the bracket 1 , and the guide rail bottom plate 32 or the guide rail vertical plate 31 is connected to the guide rail driving mechanism 8 .

[0075] When the guide rail drive mechanism 8 is in the initial state, there is a preset distance between the guide rail bottom plate 32 and the material loading pallet 2. When the first push plate mechanism 5 pushes the material 10 toward the side of the linear guide rail 3, the guide rail drive mechanism 8 starts to move, driving the linear guide rail 3 to move toward the side of the material loading pallet 2, actively receiving the material 10, and the guide rail vertical plate 31 and the first push plate 52 clamp all the materials 10 together. When a row of materials 10 are completely pushed onto the guide rail bottom plate 32, the guide rail drive mechanism 8 drives the linear guide rail 3 to reset, the guide rail bottom plate 32 leaves the material loading pallet 2, and the row of materials 10 on the guide rail bottom plate 32 is separated from the materials 10 on the material loading pallet 2. At this time, the second push plate mechanism 6 can push the materials 10 on the guide rail bottom plate 32.

[0076] In one embodiment, if Figure 1-2 As shown, the edges of the material carrying pallet 2 are connected with detachable pallet baffles 21. Before stacking the materials 10, the pallet baffles 21 are installed on the edges of the material carrying pallet 21 to facilitate stacking of the materials 10. After stacking the materials 10, the pallet baffles 21 are removed to avoid affecting the movement of the materials 10.

[0077] In one embodiment, if Figure 1-2 and Figure 4-7 As shown, the first push plate mechanism 5 includes a first driving member 51 connected to the bracket 1 and a first push plate 52 connected to the first driving member 51 .

[0078] The first push plate 52 is arranged in parallel with the linear guide rail 3 , and the first driving member 51 is used to drive the first push plate 52 to move toward the linear guide rail 3 .

[0079] When the first driving member 51 is in the initial state, the first push plate 52 and the linear guide rail 3 are located at opposite sides of the material carrying plate 2 .

[0080] In this embodiment, the first push plate mechanism 5 includes a first driving member 51 and a first push plate 52. The first driving member 51 is a linear pushing member, which can be a piston member or a motor screw member. The first driving member 51 is connected to the bracket 1, and its output end or movable part (for example, a piston rod, a screw nut) can move along the left and right direction of the material support plate 2. The first push plate 52 is connected to the output end or movable part of the first driving member 51. The first push plate 52 is arranged in parallel with the linear guide 3, and a preset gap is spaced between the lower end of the first push plate 52 and the material support plate 2, and the gap is less than the height of a piece of material 10. Of course, the lower end of the first push plate 52 can also be attached to the upper surface of the material support plate 2. When the first driving member 51 is in the initial state, its output end or movable part is reset, and the first push plate 52 and the linear guide 3 are on opposite sides of the material support plate 2, that is, the first push plate 52 and the linear guide 3 are on the left and right sides of the material support plate 2. When the first driving member 51 is in motion, its output end or movable part drives the first push plate 52 to move toward the linear guide rail 3, thereby pushing all the materials 10 on the material support plate 2 toward the linear guide rail 3. After the row of materials 10 closest to the linear guide rail 3 enters the linear guide rail 3, the first driving member 51 stops. When the next row of materials 10 needs to be pushed, the first driving member 51 is in motion again. After completely pushing the materials 10 on the material support plate 2, the first driving member 51 drives its output end or movable part to reset, thereby driving the first push plate 52 back to the initial position.

[0081] As required, a detection element, such as a sensor or a limit switch, may be configured in the linear guide 3 to determine whether there is material 10 in the linear guide 3. The detection element is connected to the control system signal of the automatic feeding device. When the detection element detects that there is a row of materials 10 in the linear guide 3, a signal is sent to the control system, and the control system controls the first driving member 51 to stop.

[0082] As required, the distance pushed by the first push plate 52 each time can be set to be the width of the material 10 along the left and right direction. After pushing once, a row of materials 10 closest to the linear guide rail 3 enters the linear guide rail 3, and the first driving member 51 stops.

[0083] In one embodiment, if Figure 1-2 and Figure 7 As shown, the first push plate mechanism 5 includes a connecting frame 53 and a slide rail 54 . The slide rail 54 and the first driving member 51 are connected to opposite sides of the bracket 1 , and the slide rail 54 is slidably connected to the bracket 1 .

[0084] The connecting frame 53 is connected between the slide rail 54 and the first driving member 51 , and the first push plate 52 is connected to the connecting frame 53 .

[0085] In this embodiment, the first push plate mechanism 5 also includes a connecting frame 53 and a slide rail 54. The slide rail 54 is arranged opposite to the first driving member 51. The first driving member 51 is connected to the rear side of the bracket 1, and the slide rail 54 is connected to the front side of the bracket 1. The slide rail 54 is slidably connected to the bracket 1 and can slide relative to the bracket 1. The connecting frame 53 is a U-shaped bracket, one end of the connecting frame 53 is connected to the slide rail 54, and the other end is connected to the output end or movable part of the first driving member 51. The first push plate 52 is connected to the connecting frame 53, and the first push plate 52 is connected to the inner side of the U-shaped bracket, which improves the connection stability of the first push plate 52 and the stability of driving the first push plate 52 to move.

[0086] In one embodiment, if Figure 1-2 , Figure 4-6 and Figure 8-9 As shown, the second push plate mechanism 6 includes a second driving member 61 connected to the bracket 1 and a second push plate 62 connected to the second driving member 61 , and the second driving member 61 is used to drive the second push plate 62 to move toward the discharge rack 33 side.

[0087] When the second driving member 61 is in the initial state, the second push plate 62 and the unloading rack 33 are located at opposite ends of the linear guide rail 3 .

[0088] In this embodiment, the second push plate mechanism 6 includes a second drive member 61 and a second push plate 62. The second drive member 61 is a linear push member, which can be a piston member or a motor screw member. The second drive member 61 is connected to the bracket 1, and its output end or movable part (for example, a piston rod, a screw nut) can move along the front and rear direction. The second push plate 62 is connected to the output end or movable part of the second drive member 61. The second push plate 62 can be connected to the output end or movable part of the second drive member 61 through a connecting plate 63.

[0089] The second push plate 62 is in the linear guide 3, and there is a preset gap between the lower end of the second push plate 62 and the bottom plate of the linear guide 3, which is smaller than the height of a piece of material 10. Of course, the lower end of the second push plate 62 can also be attached to the bottom plate of the linear guide 3. When the second driving member 61 is in the initial state, its output end or movable part is reset, and the second push plate 62 and the discharge rack 33 are at opposite ends of the linear guide 3, that is, the second push plate 62 is at the rear end of the linear guide 3. When the second driving member 61 is actuated, its output end or movable part drives the second push plate 62 to move forward, and then pushes all the materials 10 on the linear guide 3 forward. After the frontmost piece of material 10 enters the discharge rack 33, the second driving member 61 stops. When it is necessary to push the next piece or a group of materials 10, the second driving member 61 is actuated again. After completely pushing the materials 10 on the linear guide 3, the second driving member 61 drives its output end or movable part to reset, and then drives the second push plate 62 back to the initial position.

[0090] As required, a detection element, such as a sensor or a limit switch, may be configured in the discharge rack 33 to determine whether there is material 10 in the discharge rack 33. The detection element is connected to the control system signal of the automatic feeding device. When the detection element detects that there is a row of materials 10 in the discharge rack 33, a signal is sent to the control system, and the control system controls the second driving member 61 to stop.

[0091] As required, the distance pushed by the second push plate 62 each time can be set to be the length of the material 10 along the front-rear direction. After pushing once, the frontmost material 10 enters the discharge rack 33, and the second driving member 61 stops.

[0092] In one embodiment, if Figure 1-2 , Figure 4-5 and Figure 10-11 As shown, the manipulator mechanism 7 includes a clamp 71 for clamping the material 10 , a lifting drive component 72 for driving the clamp 71 to move up and down, and a third drive component 73 for driving the lifting drive component 72 to reciprocate along the loading platform 4 .

[0093] The third driving member 73 is connected to the bracket 1 , the lifting driving member 72 is connected to the third driving member 73 , and the clamp 71 is connected to the lifting driving member 72 .

[0094] In this embodiment, the manipulator mechanism 7 includes a clamp 71, a lifting drive component 72 and a third drive component 73.
