Detailed Description

Embodiments of the present application are described in detail below with reference to the accompanying drawings. It should be noted that the following description is merely exemplary in nature and is not intended to limit the present application. Further, in the following description, the same reference numbers will be used to refer to the same or like parts in different drawings. The different features in the different embodiments described below can be combined with each other to form further embodiments within the scope of the application.

Fig. 1 shows a schematic view of a vacuum suction device of a logistics object according to an embodiment of the present application. As shown in fig. 1, the vacuum chuck apparatus 100 may include a deformable frame 110, a central chuck 120, and a side chuck 130. The deformable frame 110 has a first posture and a second posture, and is deformable between the first posture and the second posture. Fig. 1 shows a first posture of the deformable frame 110. Figure 2 illustrates a schematic view of a vacuum chuck assembly with a deformable frame in a second position according to one embodiment of the present application. As shown in fig. 1 and 2, the central suction tool 120 is disposed at a central portion of the deformable frame 110, and the side suction tools 130 are installed at side portions of the deformable frame 110. The side suction tool 130 is movable with the deformation of the deformable frame 110 between the first posture shown in fig. 1 and the second posture shown in fig. 2. Since the frame of the vacuum chuck device is deformable and the side chucks can move with the deformation of the frame between two attitudes, the top of the physical distribution object can be adsorbed by the central chuck and the side of the physical distribution object can be adsorbed by the side chucks, thereby generating adsorption on the physical distribution object in multiple directions to improve adsorption strength and being capable of coping with physical distribution objects having non-planar surfaces or easily deformable surfaces.

The vacuum chuck apparatus 100 may include a plurality of side chucks 130 (two as shown in fig. 1 and 2), and the side chucks 130 are respectively located at both sides of the central chuck 120. In the first posture (as shown in fig. 1) of the deformable frame 110, the side suction cups 130 are located substantially on the same horizontal plane as the central suction cup 120, and the arrangement of the respective suction cups is such that the side suction cups 130 and the central suction cup 120 can each downwardly adsorb the top surface of the object of the flow to be adsorbed. This facilitates the simultaneous adsorption of larger sized objects of the stream by means of a plurality of suction tools, to improve the adsorption strength.

In the second posture of the deformable frame 110 (shown in fig. 2), the side suction tool 130 is located lower than the central suction tool 120. Also, the suction direction of the side suction tool 130 at this time is toward the lateral direction or the lateral downward direction, so that the side suction tool 130 can laterally suck the side surface of the object of the physical flow to be sucked in the second posture of the deformable frame 110. The central and lateral suction units may be standard modules such as suction cups, for example, bellows suction cups. Particularly, when the corrugated pipe sucking disc is adopted as the side suction tool, the adsorption surface of the suction tool can adaptively adjust the adsorption direction along with the angle of the surface of the logistics object to be adsorbed due to the flexibility of the corrugated pipe, and can flexibly stretch and retract, so that the adsorption strength of the logistics object is improved.

As shown in fig. 1 and 2, the deformable frame 110 may include a central top plate 111, a central bottom plate 112, side bottom plates 113, and side bars 114. The central top plate 111 is located at the top center position of the deformable frame 110, and the central bottom plate 112 is located at the bottom center position of the deformable frame 110. The central top plate 111 and the central bottom plate 112 are disposed parallel and opposite to each other, and the central top plate 111 and the central bottom plate 112 approach or move away from each other during the deformation of the deformable frame 110, but are always kept parallel. The central suction tool 120 can be disposed adjacent to the central base plate 112, e.g., can be mounted directly or indirectly via other components on the central base plate 112. The side bottom plates 113 may have two symmetrically arranged side bottom plates, are located at both sides of the central bottom plate 112 at the bottom of the deformable frame 110, and are rotatably connected with the central bottom plate 112 through a rotating shaft. For example, the ends of the side bottom plates 113 and the central bottom plate 112 connected to each other may be hinge bases at one end and hinge heads at the other end, and connected to each other by a rotation shaft. The side suction tool 130 may be mounted on the side base plate 113, for example, by screw fixing connection. The two side rods 114 may be symmetrically disposed and located at both sides of the deformable frame 110, and both ends of the side rods 114 are rotatably connected to the central top plate 111 and the side bottom plate 113 through a rotation shaft, respectively, in the same manner as the side bottom plate 113 and the central bottom plate 112. To reduce friction and wear, the connecting shafts of the deformable frame 110 may be sleeved with brass sleeves. With the above arrangement, the deformable frame 110 can be deformed between the first posture and the second posture when driven by an external force to achieve different suction states.

Referring again to fig. 1 and 2, the vacuum chuck apparatus 100 may further include a central guide bar 140 and a linear actuator 150. The linear actuator 150 is an active mechanism of the entire apparatus 100, outputs linear motion, provides driving force for the movement of the suckers 120, 130 and the deformation of the deformable frame 110, and may employ a cylinder, a linear motor, a combination of a motor and a lead screw nut, and the like. The linear actuator 150 may be mounted on the central top plate 111 and may have an extension rod 151 that can be extended and retracted downward. According to one embodiment, the linear actuator also has an actuator body 152. As shown in fig. 1, the driver body 152 may be mounted on the center top plate 111. For example, the lower end of the driver body 152 and the central top plate 111 have pin holes corresponding to each other and are connected by screws. In this way, the mounting position of the protruding rod 151 can also be ensured to be accurate. Referring again to fig. 1 and 2, a boss 111A may be provided in a central region of an upper surface of the central top plate 111, a lower end of the driver body 152 may be attached to the boss 111A, and pin holes of the boss 111A and pin holes of the lower end of the driver body may correspond to each other and be coupled by screws.

A connector 153 (shown in fig. 1) may be disposed at an upper end of the driver body 152, and the connector 153 may be screwed with a control mechanism (e.g., a robot, a robotic arm, etc.), so that the control mechanism may control the entire apparatus 100.

Fig. 3 shows a schematic view of a vacuum chuck device with a protruding rod protruding downward according to an embodiment of the present application. Figure 4 illustrates a top view of a center floor and side floors according to one embodiment of the present application. In fig. 2 and 3, the driver body 152 is not shown in order to clearly illustrate the operation of the protruding rod 151. For clarity of the driver body 152, the protruding rod 151 is also not shown in fig. 1. The protruding rod 151 may pass through a first fitting hole (not shown) of the center top plate 111 and a second fitting hole 112A of the center bottom plate 112 to be screw-coupled with the center guide rod 140 to drive the center guide rod 140 to move in a vertical direction. The central suction tool 120 may be installed at the lower end of the central guide bar 140 so as to be movable together with the central guide bar 140. According to one embodiment, the protruding rod 151 may be a square rod. Accordingly, the first engagement hole of the center top plate 111 may be a square hole to be engaged with the protrusion rod 151 through a shaft hole, and this arrangement prevents the protrusion rod 151 from rotating relative to the transformable frame 110. In the first posture of the transformable frame 110 as shown in fig. 1, the central guide bar 140 and the second fitting hole 112A of the central base plate 112 may be shaft-hole fitted. The central guide bar 140 may have a chamfer and a radiused transition (as shown in fig. 3) at its upper end to facilitate axial hole mating with the second mating hole 112A.

The center guide bar 140 may have a lower end flange 141 at a lower end thereof, the lower end flange 141 being positioned below the center base plate 112, and the lower end flange 141 being larger in size than the second coupling hole 112A of the center base plate 112. Thus, as the central guide rod 140 ascends, the lower flange 141 abuts against the lower surface of the central base plate 112, and pushes the central base plate 112 to ascend together. In addition, the central suction tool 120 may be mounted on the lower end flange 141 and move in unison with the central guide rod 140.

As shown in fig. 3, the vacuum chuck apparatus 100 may further include a stopper 160. A plurality of fixing holes 142 having different heights may be provided on a side surface of the central guide bar 140, and a stopper 160 may be detachably mounted (e.g., by a screw) to one of the plurality of fixing holes 142 to define a relative position of the central guide bar 140 to the central base plate 112. When the limiting block 160 is not installed, and the central guide rod 140 is driven by the extension rod 151 of the driver 150 to ascend, the lower flange 141 of the central guide rod 140 abuts against the lower surface of the central base plate 112 to drive the central base plate 112 to move upwards; when the stop block 160 is installed, the stop block 160 abuts against the lower surface of the central base plate 112 and drives the central base plate 112 to move upward. Since the fixing holes 142 can be fixed to different ones, the position adjustment of the stopper 160 on the central guide bar 140 can change the final posture of the deformable frame, thereby changing the position and angle of the side suction tool 130 to achieve the adaptive adjustment for different objects to be adsorbed.

The vacuum chuck apparatus 100 may further include a guide bar 170 and a spring 180. The guide bar 170 has upper and lower ends, and the lower end of the guide bar 170 is screw-coupled to a mounting hole 112B (shown in fig. 4) of the center base plate 112 to fix the lower end of the guide bar 170 to the center base plate 112. The upper end of the guide bar 170 passes through a third fitting hole (not shown) of the center top plate 111, and the guide bar 170 can move upward through the third fitting hole. A stopper 171 is provided at an upper end of the guide bar 170, and the stopper 171 has a size larger than that of the third engagement hole of the center top plate 111. For example, when the boss 111A is provided in the central region of the upper surface of the center top plate 111, the stopper 171 of the guide bar 170 may be fitted to the boss 111A. Therefore, the limiting table 171 may function as a limiting function such that the tip of the guide bar 170 is kept above the center top plate 111 and not lower than the center top plate 111. Since the stem 170 is substantially rigid, the maximum distance between the central top panel 111 and the central bottom panel 112 of the deformable frame 110 is substantially equal to the length of the stem 170 (i.e., as shown in fig. 1). The spring 180 is fitted over the outer surface of the guide bar 170 and has upper and lower ends. The upper end of the spring 180 abuts against the lower surface of the center top plate 111, and the lower end of the spring 180 abuts against the upper surface of the center bottom plate 112.

In the first posture of the deformable frame 110 shown in fig. 1, the spring 180 is in a relaxed state or a compressed state. At this time, since the lower ends of the guide rods 170 are fixedly coupled to the center bottom plate 112, the upper ends of the guide rods 170 pass through the center top plate 111, and the stopper 171 of the guide rods 170 abuts on the upper surface of the center top plate 111, so that the center top plate 111 and the center bottom plate 112 do not move away from each other any more. When the central base plate 112 is raised relative to the central top plate 111 by the linear actuator 150, the upper ends of the guide rods 170 are raised through the third fitting holes of the central top plate 111 until the second posture of the deformable frame 110 (shown in fig. 2) is reached, at which time the springs 180 are in a compressed state. When the linear actuator 150 drives the central guide rod 140 back to the position shown in fig. 1, the central base plate 112 will be lowered under spring tension relative to the central top plate 111, thereby returning the deformable frame 110 to the first attitude.

The operation of the vacuum chuck apparatus 100 for adsorbing the material flow object will be described with reference to the drawings.

As shown in fig. 1, in the initial state of the apparatus 100, the deformable frame 110 may be in the first posture, in which the extension bars 151 of the linear actuator 150 (the extension bars 151 are connected to the central guide bar 140) may extend downward from the central top plate 111 by a distance such that the central suction tool 120 and the side suction tools 130 are in a substantially flush position. At this time, the side bottom plates 113 are substantially parallel to the center bottom plate 112, and the lower surface of the center bottom plate 112 is attached to the upper surface of the lower end flange 141 of the stopper 160 or the center guide bar 140. The apparatus 100 shown in fig. 1 can be adapted to adsorb a material flow object having a large top surface because the central suction tool 120 and the side suction tools 130 are substantially at the same level, and a plurality of suction tools can be simultaneously adsorbed on the top surface of the material flow object to generate a stronger adsorption force.

However, when the top surface of the object of the material flow to be adsorbed is small or stacked in a narrow space and thus it is not easy to adopt the posture shown in fig. 1 for adsorption, as shown in fig. 3, the central guide bar 140 may be moved downward by the driving of the extension bar 151 so that the central suction tool 120 is lower than the side suction tools 130, and thus, the central suction tool 120 may be extended downward from the deformable frame 110 to independently adsorb the object of the material flow. In this state, only the central suction tool 120 is extended, and the side suction tools 130 maintain the initial position. If the object to be adsorbed is light and not fragile, the device 100 can be directly controlled to carry the object; otherwise, it is necessary to retract the extension rod 151 of the linear actuator 150, pulling the central suction tool 120 and the object of the stream to be adsorbed to rise.

With the retraction of the extended rod 151 of the linear actuator 150, the vacuum chuck device 100 will return to the state shown in fig. 1. At this time, the transformable frame 110 is in the first posture, and the stopper 160 or the lower end flange 141 of the center guide bar 140 is in contact with the lower surface of the center base plate 112. As the extension rod 151 continues to retract, the deformable frame will deform from the first posture to the second posture (as shown in fig. 2). In the process of deforming the deformable frame 110 from the first posture to the second posture, the central guide bar 140 is driven by the extension bar 151 to ascend, so that the lower end flange 141 or the stopper 160 mounted on the fixing hole 142 of the central guide bar 140 abuts against the lower surface of the central base plate 112 and drives the central base plate 112 and the central suction tool 120 to ascend together. The rising of the central bottom plate 112 causes the side bottom plates 113 and the side bars 114 to turn inward so that the side suction tools 130 can laterally suck the side of the object of the material flow to be adsorbed in the second posture of the deformable frame 110. At this time, the vacuum suction apparatus 100 has a high adsorption strength to the physical distribution object, so that it can be automatically transported.

When the physical distribution object has been carried to a specified position by the vacuum chuck apparatus 100 and needs to be released, the side chucks 130 may be released, and the deformable frame 110 is deformed from the second posture to the first posture, and the central chuck 120 is released, so that the physical distribution object is released from the adsorption of the vacuum chuck apparatus 100. During the process of deforming the deformable frame 110 from the second posture to the first posture, the central guide bar 140 is driven to descend by the extension bar 151, so as to drive the central suction tool 120 to descend together. The central bottom plate 112 moves downward away from the central top plate 111 under the tension of the spring 180. The lower surface of the central base plate 112 abuts against the lower end flange 141 or the stopper 160 mounted on the fixing hole 142 of the central guide bar 140. The lowering of the central floor 112 causes the side floors 113 and the side bars 114 to pivot outwardly until the first attitude of the deformable frame 110.

The vacuum chuck device 100 may further include a buffer sheet 190. A buffer sheet 190 is provided on the lower surface of the center top plate 111 to buffer the upward collision of the tip of the center guide bar 140 and to limit the rising highest position of the center guide bar 140. The central guide bar 140 is continuously raised while the deformable frame is deformed from the first posture to the second posture, and the raising may be stopped when a designated position is reached or when the object of the stream has been sucked by the central suction tool 120 and the side suction tool 130 together. Alternatively, the lift may be stopped when the tip of the center guide bar 140 collides with the buffer piece 190. Therefore, the buffer sheet 190 plays a role of buffering the collision of the center guide bar 140 against the center top plate 111 and can play a role of a stopper.

Referring again to fig. 4, the side bottom plate 113 is provided with a plurality of suction tool mounting holes 113A for mounting the side suction tools 130. The side suction tool 130 can be installed at a suitable installation hole 113A according to the size of the object of the material flow to be adsorbed. A pneumatic connector (not shown) may be provided at the upper end of the side suction tool 130 for connecting a negative pressure air source.

According to one embodiment, the central suction unit 120 may include a gas distribution member 121 and a suction cup 122. The gas distribution member 121 may have an upper end flange 121A at an upper end, and the upper end flange 121A is fixedly coupled (e.g., coupled by screws) to a lower end flange 141 of the center guide bar 140. The upper end flange 121A may have a slot hole therein so that the installation angle can be adjusted. The gas distributing member 121 has an internal gas path and a pneumatic connector communicating with the internal gas path, and the pneumatic connector can be connected to a negative pressure gas source. The suction cup 122 is installed below the air distribution member 121 and is communicated with an internal air passage of the air distribution member 121. For example, the suction cup 122 may be a bellows suction cup, which has good adaptability and can be a main suction cup for sucking the material flow.

Although the above description includes many specific arrangements and parameters, it should be noted that these specific arrangements and parameters are merely illustrative of one embodiment of the present application. This should not be taken as limiting the scope of the application. Those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the application. Accordingly, the scope of the application should be construed based on the claims.
