[0028] Please refer to Figures 1 to 3 The embodiment of the present application provides an automatic pick-up device 100, including a workbench 10, and an adsorption mechanism 20 and a material-forming mechanism 30 arranged on the workbench 10. The adsorption mechanism 20 and the material-forming mechanism 30 are arranged on the same side of the processing device 200, and the adsorption mechanism 20 is located above the material-forming mechanism 30. The adsorption mechanism 20 is driven to move toward or away from the side of the processing device 200. The adsorption mechanism 20 is used to adsorb the workpiece 300 processed by the processing device 200, so as to transport the workpiece 300 to the unloading position C located in front of the material-forming mechanism 30. The adsorption mechanism 20 is also used to push the workpiece 300 located at the unloading position C into the material-forming mechanism 30, so that multiple workpieces 300 are stacked in sequence in the material-forming mechanism 30. The automatic pick-up device 100 can solve the problems of low unloading efficiency and high labor intensity in the blade processing process in the prior art.

[0029] It should be noted that if Figure 1 and Figure 2As shown, the automatic pick-up device 100 includes a workbench 10, on which an adsorption mechanism 20 and a material-forming mechanism 30 are respectively arranged, wherein the adsorption mechanism 20 and the material-forming mechanism 30 are arranged at intervals on the same side of the processing device 200, and the adsorption mechanism 20 is located above the material-forming mechanism 30. In the actual working process, the adsorption mechanism 20 is driven to move toward or away from the side of the processing device 200. In the above movement process, the adsorption mechanism 20 mainly plays two roles, one of which is to adsorb the workpiece 300 processed by the processing device 200 to transport the workpiece 300 to the unloading position C located in front of the material-forming mechanism 30, and the other role is to push the workpiece 300 located at the unloading position C into the material-forming mechanism 30, so that the multiple workpieces 300 adsorbed one by one by the adsorption mechanism 20 and transported to the unloading position C can be stacked in the material-forming mechanism 30 in sequence, so that it is convenient for workers to take out the multiple workpieces 300 neatly arranged in the material-forming mechanism 30 at one time.

[0030] like Figure 2 As shown, the adsorption mechanism 20 and the material-forming mechanism 30 are both arranged at intervals on the same side of the processing device 200, which means that in the horizontal direction, the adsorption mechanism 20 and the material-forming mechanism 30 are both arranged on the same side of the processing device 200, and the adsorption mechanism 20 and the material-forming mechanism 30 have a certain size of space with the processing device 200, so that the adsorption mechanism 20 and the material-forming mechanism 30 cooperate with each other to complete the adsorption and pushing actions; and the above-mentioned adsorption mechanism 20 is located above the material-forming mechanism 30, which means that in the vertical direction, the distance between the adsorption mechanism 20 and the workbench 10 is greater than the distance between the material-forming mechanism 30 and the workbench 10. Specifically, the actual height of the adsorption mechanism 20 in the vertical direction needs to be adapted to the actual height of the processing position A of the processing device 200 for placing the workpiece 300 for processing in the vertical direction, so that when the adsorption mechanism 20 moves to contact the processing device 200, the workpiece 300 that has been processed and is located at the processing position A can be successfully adsorbed by the adsorption mechanism 20.

[0031] In addition, regarding the specific way in which the adsorption mechanism 20 adsorbs the workpiece 300, those skilled in the art should be able to make reasonable selections and designs according to actual conditions, and no specific restrictions are made here. Optionally, in this embodiment, the movable plate 22 is magnetic, and the movable plate 22 is used to be fixed with the workpiece 300 by magnetic attraction, so that the plate surface of the movable plate 22 and the workpiece 300 are fixed by magnetic attraction. Of course, in other embodiments, a vacuum suction nozzle can also be provided on the movable plate 22, so that the vacuum suction nozzle on the movable plate 22 and the workpiece 300 are fixed by vacuum attraction.

[0032] Compared with the prior art, after the workpiece 300 is processed, the worker manually removes the processed workpiece 300 from the fixing fixture of the processing device 200 and places it in a packaging box for sorting and packaging. The automatic picking device 100 provided in the present application absorbs the workpiece 300 processed by the processing device 200 through the adsorption mechanism 20, so as to transport the workpiece 300 to the unloading position C located in front of the material sorting mechanism 30, and pushes the workpiece 300 located at the unloading position C into the material sorting mechanism 30 through the adsorption mechanism 20, so that multiple workpieces 300 can be stacked in the material sorting mechanism 30 in sequence. With the mutual cooperation of the adsorption mechanism 20 and the material sorting mechanism 30, the unloading efficiency can be effectively improved and the labor intensity can be reduced, thereby solving the problems of low unloading efficiency and high labor intensity in the blade processing process in the prior art.

[0033] Alternatively, if Figure 1 and Figure 2 As shown, in this embodiment, the automatic pick-up device 100 further includes a driving mechanism 40, which is connected to the adsorption mechanism 20, and is used to drive the adsorption mechanism 20 to move toward or away from the processing device 200, so as to provide a driving action for the adsorption mechanism 20 through the driving mechanism 40, so that the adsorption mechanism 20 can move toward or away from the processing device 200 under the driving action of the driving mechanism 40. The driving mechanism 40 can be a linear motion mechanism capable of linear motion, such as a pneumatic cylinder, a hydraulic cylinder or a linear motor. For example, Figure 2 As shown, in this embodiment, the driving mechanism 40 includes a mounting seat 41 and a driving member 42 fixedly arranged on the mounting seat 41, and the output shaft 43 of the driving member 42 is connected to the adsorption mechanism 20, and the output shaft 43 of the driving member 42 can be extended and retracted. When the output shaft 43 of the driving member 42 is extended relative to the processing device 200, the adsorption mechanism 20 moves toward the side close to the processing device 200; when the output shaft 43 of the driving member 42 is retracted relative to the processing device 200, the adsorption mechanism 20 moves toward the side away from the processing device 200.

[0034] Alternatively, if Figure 2 and Figure 3As shown, in this embodiment, the adsorption mechanism 20 includes a fixed plate 21 and a movable plate 22, the fixed plate 21 is connected to the driving mechanism 40, and the movable plate 22 is hinged to the fixed plate 21, so that the movable plate 22 can swing relative to the fixed plate 21. In this way, when the adsorption mechanism 20 moves toward the side close to the processing device 200 to contact the processing device 200, the movable plate 22 can be swung relative to the fixed plate 21 until the movable plate 22 is in a vertical downward state, so that it can be ensured that the movable plate 22 can be in contact with the workpiece 300 that has been processed and is located at the processing position A, so that the movable plate 22 can reliably adsorb the workpiece 300; when the adsorption mechanism 20 moves toward the side close to the processing device 200 to the material discharge position C and the material discharge position C is placed with the workpiece 300 at this time, the movable plate 22 can be swung relative to the fixed plate 21 until the movable plate 22 is in a tilted backward state, so that it can be ensured that the workpiece 300 placed at the material discharge position C at this time will not interfere with the movable plate 22 continuing to move toward the side close to the processing device 200.

[0035] It should be noted that the above-mentioned workpiece 300 is transported to the unloading position C located in front of the material sorting mechanism 30, and the movable plate 22 is swung relative to the fixed plate 21 until the movable plate 22 is in a tilted backward state. The front and backward mentioned are for the sake of ease of understanding. The side where the processing device 200 is located is the front and the other side away from the processing device 200 is the rear. This is a simple explanation and does not serve as a limitation.

[0036] Alternatively, if Figure 3 As shown, in this embodiment, the adsorption mechanism 20 includes a hinge shaft 23 and a torsion spring 24, the fixed plate 21, the movable plate 22 and the torsion spring 24 are sleeved on the hinge shaft 23, and the opposite ends of the torsion spring 24 are respectively connected to the fixed plate 21 and the movable plate 22. When the movable plate 22 is not subjected to external force, the torsion spring 24 can limit the angle between the fixed plate 21 and the movable plate 22. For example, Figure 2 As shown, in this embodiment, during the process of the adsorption mechanism 20 moving toward the side away from the processing device 200 to the unloading position C, the movable plate 22 is not subjected to any external force. At this time, the angle between the fixed plate 21 and the movable plate 22 is always maintained at 90° under the action of the torsion spring 24.

[0037] Alternatively, if Figure 2As shown, in the present embodiment, the material-forming mechanism 30 includes two limiting walls 31 which are parallel and spaced apart, and an entrance 32 of the material-forming mechanism 30 is formed between the two limiting walls 31 at one end close to the processing device 200, and the material-discharging position C is located in front of the material-forming mechanism 30, that is, the material-discharging position C is located in front of the entrance 32 of the material-discharging mechanism 30, and the movement direction of the adsorption mechanism 20 is parallel to the extension direction of the limiting walls 31 to ensure that the workpiece 300 can be pushed straight into the material-forming mechanism 30, and the adsorption mechanism 20 is used to push the workpiece 300 located at the material-discharging position C through the entrance 32 of the material-discharging mechanism 30 into the material-discharging mechanism 30, thereby completing the adsorption and material-discharging actions of the adsorption mechanism 20.

[0038] Alternatively, if Figure 1 As shown, in this embodiment, the front ends of the two limiting walls 31 are provided with first stoppers 33, and the first stoppers 33 are used to collide with the workpiece 300 adsorbed by the adsorption mechanism 20, so that the workpiece 300 is separated from the adsorption mechanism 20 and falls to the material discharge position C. That is to say, after the adsorption mechanism 20 adsorbs the workpiece 300, it will move toward the side away from the processing device 200. When the workpiece 300 is moved to the point where it collides with the first stoppers 33, the workpiece 300 will be separated from the adsorption mechanism 20 and fall to the material discharge position C under the action of gravity, while the adsorption mechanism 20 continues to move toward the side away from the processing device 200. The position where the workpiece 300 collides with the first stoppers 33 is referred to as the material discharge position B.

[0039] Regardless of whether the movable plate 22 realizes a fixed adsorption mode with the workpiece 300 through magnetic adsorption or a fixed adsorption mode with the workpiece 300 through vacuum adsorption, the above-mentioned unloading mode in which the first stop block 33 contacts the workpiece 300 adsorbed by the adsorption mechanism 20 to separate the workpiece 300 from the adsorption mechanism 20 and drop it to the unloading position C requires ensuring that the adsorption force between the adsorption mechanism 20 and the workpiece 300 is smaller than the stopping force of the first stop block 33 on the workpiece 300 to avoid damage to the workpiece 300.

[0040] Alternatively, if Figure 2As shown, in this embodiment, a second stopper 11 is provided on the workbench 10, and the second stopper 11 is spaced apart from the entrance 32 of the material-forming mechanism 30, and a material discharge position C is formed between the second stopper 11 and the entrance 32 of the material-forming mechanism 30, and the second stopper 11 is used to interfere with the workpiece 300 located at the material discharge position C to limit the workpiece 300. When the adsorption mechanism 20 moves to the unloading position C toward the side close to the processing device 200 and the unloading position C has the workpiece 300 placed thereon, the movable plate 22 will come into conflict with the workpiece 300 placed thereon. Thus, under the action of the workpiece 300, the movable plate 22 will swing relative to the fixed plate 21 until the movable plate 22 is in a tilted backward state. In order to prevent the reaction force of the movable plate 22 on the workpiece 300 from pushing the workpiece 300 from the unloading position C toward the side close to the processing device 200, a second stop block 11 is further provided on the workbench 10. In this way, the second stop block 11 can strengthen the force of the side where the workpiece 300 is located on the movable plate 22, thereby preventing the workpiece 300 placed at the unloading position C from being displaced.

[0041] Alternatively, if Figure 2 As shown, in the present embodiment, the height of the second stopper 11 is less than or equal to the distance between the movable plate 22 and the workbench 10, so as to avoid the second stopper 11 interfering with the movable plate 22 when it passes over the workpiece 300 at the unloading position C and continues to move toward the side close to the processing device 200. The distance between the movable plate 22 and the workbench 10 is less than the height of the workpiece 300, so as to ensure that when the adsorption mechanism 20 moves toward the side away from the processing device 200 and passes through the unloading position C, the workpiece 300 placed at the unloading position C can be pushed into the material sorting mechanism 30 toward the side away from the processing device 200 through the bottom of the movable plate 22.

[0042] Alternatively, if Figure 1 As shown, in this embodiment, along the connecting line direction of the two limiting walls 31 , the distance between the two limiting walls 31 is equal to the length of the workpiece 300 , so that the two limiting walls 31 can limit the opposite ends of the workpiece 300 in the length direction of the workpiece 300 .

[0043] In summary, the working process of the automatic picking device 100 is as follows: in the initial state, the material discharge position C is in an empty state, and the adsorption mechanism 20 moves toward the side close to the processing device 200 under the driving action of the driving mechanism 40 until it contacts with the workpiece 300 located at the processing position A, and after the movable plate 22 and the workpiece 300 located at the processing position A are adsorbed, the adsorption mechanism 20 moves toward the side away from the processing device 200 to the material discharge position B under the driving action of the driving mechanism 40, at this time, the workpiece 300 adsorbed by the movable plate 22 collides with the first stopper 33, so that the workpiece 300 can be separated from the movable plate 22 and fall to the material discharge position C under the action of gravity, and the adsorption mechanism 20 continues to move toward the side away from the processing device 200; continue to pick up the workpiece 300, at this time, the material discharge position C is filled with the workpiece 300, and the adsorption mechanism 20 moves toward the side close to the processing device 200 again under the driving action of the driving mechanism 40 until it contacts with the place. The movable plate 22 contacts the workpiece 300 placed at the material discharge position C, which can make the movable plate 22 swing relative to the fixed plate 21 until the movable plate 22 is in a tilted backward state, so that the movable plate 22 can return to the vertical downward state only after it passes over the workpiece 300 placed at the material discharge position C, and continue to move toward the side close to the processing device 200 until it contacts the workpiece 300 located at the processing position A. After the movable plate 22 and the workpiece 300 located at the processing position A are adsorbed, the adsorption mechanism 20, under the driving action of the driving mechanism 40, moves toward the side away from the processing device 200 until it is about to reach the material discharge position B. The bottom of the movable plate 22 will first contact the workpiece 300 placed at the material discharge position C, and push the workpiece 300 placed at the material discharge position C into the material coding position D in the material sorting mechanism 30, and then move to the material discharge position B. At this time, the workpiece 300 adsorbed by the movable plate 22 conflicts with the first stopper 33, and falls on the material discharge position C that has just been vacated, and so on.

[0044] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.

[0045] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.
