Description

Technical Field

[0001] This utility model relates to the field of automated production technology, specifically a workpiece separation device. Background Technology

[0002] With the rapid development of the automotive industry, the level of automated production of workpieces is becoming increasingly higher. In operations such as stacking and destacking stamped workpieces, robots (manipulators) and matching end effectors are usually required to pick up the workpieces. Because the stacked workpieces are tightly attached and not easily separated, the end effector often picks up the lower workpieces when picking up the upper workpieces. At this time, the machine needs to be stopped, and the operator has to manually remove the lower workpieces. This is not only time-consuming and labor-intensive, delaying production, but also poses a risk of material falling off the robot (manipulator) while it is moving the workpieces if the operator does not detect the problem in time, leading to operation failure. This is highly dangerous and affects the level of automated production. Utility Model Content

[0043] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be described in detail below with reference to the accompanying drawings. The described embodiments are merely a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort should fall within the protection scope of this application.

[0044] Example 1

[0045] like Figure 1 and Figure 2 As shown, a workpiece separation device includes a separation component 11, a first driving component 12, and a second driving component 13.

[0046] The separation assembly 11 includes a first separation member 111 and a second separation member 112. The first separation member 111 has an installation space for accommodating the second separation member 112. The second separation member 112 is located within the installation space and is capable of moving up and down relative to the first separation member 111. A first separation plate 113 extending to one side perpendicular to the first separation member 111 is provided at the lower end of the first separation member 111. A second separation plate 114 extending to one side perpendicular to the second separation member 112 is provided at the lower end of the second separation member 112, and the first separation plate 113 and the second separation plate 114 extend in the same direction.

[0047] The fixed side of the first driving member 12 is directly or indirectly connected to the end effector frame 2, and the moving side of the first driving member 12 is connected to the first separating member 111 of the separating assembly 11. When the first driving member 12 is activated, it can drive the separating assembly 11 away from or towards the workpiece 3. The separating assembly 11 can move away from or towards the workpiece 3 by swinging or translating.

[0048] The second driving member 13 is used to drive the second separating member 112 to move up and down relative to the first separating member 111. The thickness of the first separating plate 113 and the second separating plate 114 is less than the distance between the workpieces 3.

[0049] The first driving member 12 and the second driving member 13 are both linear driving members, which can be cylinders, hydraulic cylinders, or electric actuators. In one specific embodiment, both the first driving member 12 and the second driving member 13 in this embodiment are cylinders.

[0050] In one specific embodiment, the first separating member 111 in this embodiment includes a web 1111, and two wing plates 1112 extending perpendicularly to the web 1111 and towards the same side are respectively provided on both sides of the web 1111. The web 1111 and the wing plates 1112 together form a U-shaped structure with the opening facing one side. The first separating plate 113 is disposed at the lower end of the wing plate 1112, and the extending direction of the first separating plate 113 is the same as the opening direction of the first separating member 111. Preferably, the lower side surface of the first separating plate 113 is flush with the lower side surface of the wing plate 1112.

[0051] The second separating member 112 is located between the two wing plates 1112 of the first separating member 111. A pin 1113 is provided between the two wing plates 1112 on the side of the second separating member 112 facing away from the web plate 1111. The pin 1113 is located in the middle of the wing plate 1112, and both ends of the pin 1113 are respectively inserted into the wing plate 1112 and are detachably fixedly connected to the wing plate 1112. Here, the middle position is not necessarily the exact center of the wing plate 1112, but rather a position roughly in the middle, which can be a certain distance above or below the absolute center position.

[0052] The second driving member 13 is located above the first driving member 12, and the moving side of the second driving member 13 faces downward. The fixed side of the second driving member 13 is connected to the second separating member 112 via a mounting base. The mounting base includes a mounting plate 141 and a connecting rod 142 disposed at the center of the mounting plate 141 and extending upward perpendicularly to the mounting plate 141. The fixed side of the second driving member 13 is detachably fixedly connected to one end of the mounting plate 141, and the moving side of the second driving member 13 is detachably connected to the fixed side of the first driving member 12. The upper end of the second separating member 112 is hinged to an ear plate 1411 disposed at the other end of the mounting plate 141 via a hinge shaft 15.

[0053] When the first driving member 12 is activated, it can drive the separation assembly 11 to swing around the hinge axis 15, moving away from or towards the workpiece 3 to be picked up. The function of the pin 1113 is that when the first driving member 12 drives the separation assembly 11 to swing away from the workpiece 3, the pin 1113 can push the second separation member 112 to move, so that the second separation member 112 and the first separation member 111 swing synchronously.

[0054] The mounting base is detachably connected to the end effector frame 2. That is, in this embodiment, the fixed side of the first drive member 12 is indirectly connected to the end effector frame 2 through the second drive member 13.

[0055] In one specific embodiment, the first driving member 12 is located on the opening side of the first separating member 111. A first connecting plate 1114 is provided on the upper end of the first separating member 111 on the opening side, and the first connecting plate 1114 is fixedly connected to the two wing plates 1112 by welding. For example, the upper surface of the first connecting plate 1114 is flush with the upper surface of the wing plate 1112. The movable side of the first driving member 12 is detachably connected and fixed to the first connecting plate 1114.

[0056] Preferably, both the first driving member 12 and the second driving member 13 are cylinders with guide rods. The cylinder with guide rods includes a cylinder body, a movable connecting plate, a piston rod, and guide posts. The rod end of the piston rod is connected to the movable connecting plate. Guide posts are respectively provided on both sides of the piston rod on the movable connecting plate. One end of each guide post is fixedly connected to the movable connecting plate, and the other end of each guide post is slidably engaged with a guide hole provided on the cylinder body. The movable connecting plate of the first driving member 12 is detachably connected and fixed to the first connecting plate 1114. A detachable second connecting plate 121 is fixedly provided on the fixed side of the first driving member 12 (i.e., on the cylinder body of the first driving member 12), and the movable connecting plate of the second driving member 13 is detachably connected and fixed to the second connecting plate 121.

[0057] like Figure 3 and Figure 4 As shown, in actual production, depending on the size of the workpiece 3, one or more workpiece 3 separation devices provided in this application can be connected to the end effector to jointly lift the workpiece 3. This application uses one workpiece 3 separation device as an example to illustrate its working process:

[0058] First, the end effector moves to the pickup position above the workpiece 3. The first drive member 12 pushes the separation assembly 11 to move away from the workpiece 3, so that the second separation plate 114 and the first separation plate 113 are outside the projection range of the horizontal plane where the workpiece 3 is located. Then, the end effector moves down, so that the first separation plate 113 and the second separation plate 114 of the separation assembly 11 are aligned with the positions of the two workpieces 3 to be separated. Then, the first drive member 12 pulls the separation assembly 11 to move closer to the workpiece 3, and with the fine adjustment of the second drive member 13, the first separation plate 113 and the second separation plate 114 are inserted between the two workpieces 3 to be separated. Then, the second drive member 13 pulls the first drive member 12 upward, thereby driving the first separation member 111 upward. At this time, the upper workpiece 3 is lifted by the first separation plate 113, and the lower workpiece 3 is pressed by the second separation plate 114, realizing the separation of the two workpieces 3.

[0059] Example 2

[0060] The difference between this embodiment and Embodiment 1 is that:

[0061] The second separating plate 114 is perpendicular to the second separating member 112 and extends away from the first driving member 12. The web plate is provided with a clearance slot for avoiding the second separating plate 114. The lower end of the web plate is provided with first separating plates 113 extending away from the first driving member 12 on both sides of the clearance slot.

[0062] During operation, firstly, the end effector moves to the pickup position above the workpiece 3, and the piston rod of the first drive member 12 retracts, thereby pulling the separation assembly 11 to move away from the workpiece 3, so that the second separation plate 114 and the first separation plate 113 are outside the projection range of the workpiece 3 in the horizontal plane; then the end effector moves down, so that the first separation plate 113 and the second separation plate 114 of the separation assembly 11 are aligned with the positions of the two workpieces 3 to be separated; then the piston rod of the first drive member 12 extends, thereby pushing the separation assembly 11 to move closer to the workpiece 3, and with the fine adjustment of the second drive member 13, the first separation plate 113 and the second separation plate 114 are inserted between the two workpieces 3 to be separated; then the second drive member 13 pulls the first drive member 12 upward, thereby driving the first separation member 111 upward. At this time, the upper workpiece 3 is lifted by the first separation plate 113, and the lower workpiece 3 is pressed by the second separation plate 114, realizing the separation of the two workpieces 3.

[0063] Example 3

[0064] The difference between this embodiment and Embodiment 1 is that:

[0065] like Figure 5 , Figure 6 and Figure 7 As shown, the first separating member 111 is sleeved on the outside of the second separating member 112, and the second separating member 112 is slidably connected to the first separating member 111. The second separating member 112 has only one degree of freedom to slide up and down relative to the first separating member 111.

[0066] In one specific embodiment, the first separating member 111 in this embodiment includes an outer cylinder 1115, and the second separating member 112 is located inside the outer cylinder 1115 and is slidably connected to the outer cylinder 1115 via a linear bearing 115. The second separating plate 114 is located at the lower end of the second separating member 112, and the second separating plate 114 extends through the side wall of the outer cylinder 1115 to the outside of the outer cylinder 1115. A first clearance notch 11151 for avoiding the second separating plate 114 is provided on the side wall of the lower end of the outer cylinder 1115. The first separating plate 113 is fixedly disposed at the lower end of the outer cylinder 1115, and the first separating plate 113 is provided with a second clearance notch 1131 for avoiding the second separating plate 114.

[0067] The movable side of the first driving member 12 is fixedly connected to the first separating member 111 in a detachable manner.

[0068] In one specific embodiment, the first connecting plate 1114 described in this embodiment is fixedly disposed on the upper end of the outer cylinder 1115 by welding.

[0069] The mounting plate 141 of the mounting base is detachably fixed to the fixed side of the first driving member 12, and the connecting rod 142 of the mounting base is parallel to the sliding direction of the second separating member 112 relative to the first separating member 111. That is, in this embodiment, the first driving member 12 is directly connected to the end effector frame 2.

[0070] Here, the mounting base can be disposed above or below the fixed side of the first driving member 12. In one specific embodiment, the mounting base is detachably fixed above the fixed side of the first driving member 12.

[0071] The second driving member 13 is located above the separation component 11. The fixed side of the second driving member 13 is detachably fixedly connected to the first separation component 111, and the movable side of the second driving member 13 is detachably connected to the second separation component 112.

[0072] In one specific embodiment, the upper end of the outer cylinder 1115 is fixedly provided with a third connecting plate 1116 by welding. The second driving member 13 is a common cylinder (i.e., a cylinder without a guide rod). The fixed side (i.e., the cylinder body) of the second driving member 13 is fixedly connected to the third connecting plate 1116 in a detachable manner. The moving side (i.e., the rod end of the piston rod) of the second driving member 13 passes downward through the third connecting plate 1116 and is fixedly connected to the upper end face of the second separating member 112 in a detachable manner. The third connecting plate 1116 is provided with a clearance hole for avoiding the moving side of the second driving member 13.

[0073] Furthermore, the upper end face of the first connecting plate 1114 is attached to the lower side face of the third connecting plate 1116 and is connected and fixed by welding.

[0074] In one specific embodiment, the first driving member 12 described in this embodiment is located on the side of the outer cylinder 1115 where the first clearance notch 11151 is provided.

[0075] like Figure 8 and Figure 9 As shown, its working process is as follows:

[0076] First, the end effector moves to the pickup position above the workpiece 3. The first drive member 12 pushes the separation assembly 11 to move away from the workpiece 3 in a translational manner, so that the second separation plate 114 and the first separation plate 113 are outside the projection range of the workpiece 3 in the horizontal plane. Then, the end effector moves down, so that the first separation plate 113 and the second separation plate 114 of the separation assembly 11 are aligned with the positions of the two workpieces 3 to be separated. Then, the first drive member 12 pulls the separation assembly 11 to move closer to the workpiece 3 in a translational manner, so that the first separation plate 113 and the second separation plate 114 are inserted between the two workpieces 3 to be separated. Then, the second drive member 13 pulls the second separation member 112 upward. At this time, the upper workpiece 3 is lifted by the second separation plate 114, and the lower workpiece 3 is pressed by the first separation plate 113, thus realizing the separation of the two workpieces 3.

[0077] Example 4

[0078] The difference between this embodiment and Embodiment 3 is as follows:

[0079] The first driving member 12 is located on the side of the outer cylinder 1115 opposite to the first clearance notch 11151.

[0080] During operation, firstly, the end effector moves to the pickup position above the workpiece 3, and the piston rod of the first drive member 12 retracts, thereby pulling the separation assembly 11 to move away from the workpiece 3 in a translational manner, so that the second separation plate 114 and the first separation plate 113 are outside the projection range of the workpiece 3 in the horizontal plane; then the end effector moves down, so that the first separation plate 113 and the second separation plate 114 of the separation assembly 11 are aligned with the positions of the two workpieces 3 to be separated; then the piston rod of the first drive member 12 extends, thereby pushing the separation assembly 11 to move closer to the workpiece 3 in a translational manner, so that the first separation plate 113 and the second separation plate 114 are inserted between the two workpieces 3 to be separated; then the second drive member 13 pulls the second separation member 112 upward, at which time the upper workpiece 3 is lifted by the second separation plate 114, and the lower workpiece 3 is pressed by the first separation plate 113, realizing the separation of the two workpieces 3.

[0081] Example 5

[0082] The difference between this embodiment and Embodiment 3 is as follows:

[0083] like Figure 10 As shown, the mounting plate 141 of the mounting base is detachably fixed to the side of the first driving member 12, and the sliding direction of the connecting rod 142 and the second separating member 112 relative to the first separating member 111 is perpendicular. The lower end plate of the first connecting plate 1114 is fixedly connected to the outer cylinder 1115 and the third connecting plate 1116 by welding, and the upper end surface of the first connecting plate 1114 is located above the third connecting plate 1116.

[0084] Its working process is as follows Figure 11 and Figure 12 As shown, and the same as in Example 3, it will not be described again here.

[0085] Example 6

[0086] The difference between this embodiment and embodiment four is that:

[0087] The mounting plate 141 of the mounting base is detachably fixed to the side of the first driving member 12, and the sliding direction of the connecting rod 142 and the second separating member 112 relative to the first separating member 111 is perpendicular. The lower end plate of the first connecting plate 1114 is fixedly connected to the outer cylinder 1115 and the third connecting plate 1116 by welding, and the upper end surface of the first connecting plate 1114 is located above the third connecting plate 1116.

[0088] Its working process is the same as that in Example 4, and will not be described again here.
