Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0047] like Figure 1 and Figure 2 As shown, the present application provides a material taking mechanism, including a frame 110, a clamping structure 120 and a material pocketing structure 130. The clamping structure 120 and the material pocketing structure 130 are arranged on the frame 110. The clamping structure 120 is used to clamp a workpiece, and the material pocketing structure 130 is used to clamp the workpiece clamped on the clamping structure 120 to prevent the workpiece from escaping from the clamping structure 120.

[0048] Furthermore, the clamping structure 120 is disposed on the frame 110 , and the clamping structure 120 can move along a first direction, and the clamping structure 120 is used to clamp a workpiece.

[0049] like Figure 1 As shown, the material pocket structure 130 includes a material pocket member 131, a transmission member 132 and a material pocket driving member 133. The material pocket member 131 is movably arranged on the frame 110 along the second direction, and the material pocket member 131 is used to support the workpiece clamped by the clamping structure 120, and the second direction is perpendicular to the first direction. One end of the transmission member 132 is rotatably connected to the material pocket driving member 133, and this end of the transmission member 132 can move along the first direction under the action of the material pocket driving member 133, and the other end of the transmission member 132 is rotatably connected to the material pocket member 131, and the transmission member 132 is tilted. Under the drive of the material pocket driving member 133, the transmission member 132 drives the material pocket member 131 to move along the second direction.

[0050] It can be understood that the pocket material driving member 133 is drivingly connected to the pocket material member 131 through the obliquely arranged transmission member 132, so when the pocket material driving member 133 drives one end of the transmission member 132 to move in the first direction, the pocket material member 131 can move in the second direction under the action of the transmission member 132. In other words, the transmission member 132 can convert the movement of the pocket material driving member 133 in the first direction into the movement of the pocket material member 131 in the second direction.

[0051] For example, when the clamping structure 120 moves along the first direction to grab the workpiece, the material pocket driving member 133 can drive the material pocket member 131 to move in the direction of the moving path away from the clamping structure 120 through the transmission member 132, so as to avoid interference between the clamping structure 120 and the material pocket member 131 during the movement of the clamping structure 120 along the first direction. After the clamping structure 120 clamps the workpiece and returns to the initial position, the material pocket driving member 133 can drive the material pocket member 131 to move to the bottom of the clamping structure 120 through the transmission member 132, so as to support the workpiece clamped by the clamping structure 120.

[0052] It can be seen that in the material picking mechanism 100 of the present application, the material pocket driving member 133 is driven and connected to the material pocket member 131 through an inclined transmission member 132, and the transmission member 132 can convert the movement of the material pocket driving member 133 along the first direction into the movement of the material pocket member 131 along the second direction. This driving method can not only make the material pocket member 131 move in the second direction, but also has a simple driving method, occupies less space, and is more durable.

[0053] In some embodiments, the first direction may be a vertical direction, and the second direction may be one of the horizontal directions.

[0054] For example, in some embodiments, when the material pocket driving member 133 moves in a vertical downward direction, the transmission member 132 can enable the material pocket member 131 to move in a horizontal direction away from the vertical moving path of the clamping structure 120; when the material pocket driving member 133 moves in a vertical upward direction, the transmission member 132 can enable the material pocket member 131 to move in a horizontal direction toward the vertical moving path of the clamping structure 120, so that the material pocket member 131 can move to the bottom of the clamping structure 120 to support the workpiece.

[0055] See also Figure 1 The material pocket structure 130 may further include a first guide member 134 , which is relatively disposed on the frame 110 , and both ends of the material pocket member 131 are respectively slidably disposed on the corresponding first guide member 134 .

[0056] Specifically, when the pocket material driving member 133 moves along the first direction, the transmission member 132 can drive the pocket material member 131 to move along the second direction on the first guide member 134 to ensure the stability of the movement of the pocket material member 131.

[0057] For example, the first guide members 134 may be disposed on opposite sides of the frame 110 near the bottom. The first guide members 134 may be guide rods.

[0058] Preferably, in order to facilitate the sliding of the pocket piece 131 on the guide rod, a sliding sleeve may be further provided on the guide rod, and the pocket piece 131 is connected to the sliding sleeve.

[0059] Furthermore, in some embodiments, in order to improve the stability of the pocket material piece 131 moving along the first direction, both ends of the pocket material piece 131 can be connected to a pocket material driving piece 133 through a transmission piece 132 respectively.

[0060] See also Figure 1 In some embodiments, in order to make the structure of the material picking mechanism 100 more compact, the material pocket driving member 133 can be arranged on the frame 110 above the material pocket member 131, so that the material pocket driving member 133 does not need to occupy the bottom space of the material picking mechanism 100.

[0061] Further, the pocket material driving member 133 can be located at the end side of the clamping structure 120. In this way, the pocket material driving member 133 can drive the pocket material member 131 to move, and the pocket material driving member 133 can also avoid interference with the clamping structure 120.

[0062] See also Figure 1 , the pocket material 131 can be provided with two groups.

[0063] In some embodiments, when two groups of clamping structures 120 are provided, each group of pocket material pieces 131 can respectively support a workpiece clamped by the corresponding clamping structure 120 .

[0064] In other embodiments, two groups of pocket members 131 can simultaneously support a workpiece clamped by a group of clamping structures 120 .

[0065] Furthermore, the two groups of pocket material pieces 131 may be arranged along the second direction, each group of pocket material pieces 131 is connected to the pocket material driving member 133 via a transmission member 132, and the inclination directions of the transmission members 132 connecting the two groups of pocket material pieces 131 are opposite.

[0066] In some embodiments, the transmission members 132 connected to the two groups of pocket material members 131 can be connected to the same pocket material driving member 133. In other embodiments, the transmission members 132 connected to the two groups of pocket material members 131 can be connected to one pocket material driving member 133 respectively.

[0067] In this way, when the pocket material driving member 133 moves along the first direction, the two groups of pocket material members 131 can move closer to each other or farther away from each other in the second direction, thereby realizing the opening and closing movement of the two groups of pocket material members 131.

[0068] For example, when the two groups of pocket pieces 131 move in a direction away from each other, the clamping structure 120 can move along the first direction to clamp the workpiece.

[0069] When the two groups of material pockets 131 move toward each other, the two groups of material pockets 131 can be moved to the bottom of the clamping structure 120 respectively to support the workpiece clamped by the clamping structure 120 .

[0070] In some embodiments, the material pocket driving member 133 can be a cylinder.

[0071] In some embodiments, a limiting groove may be provided on the material pocket 131 , and the limiting groove may accommodate the workpiece clamped by the clamping structure 120 to limit the workpiece.

[0072] See also Figure 1 and Figure 2 The clamping structures 120 may be provided with two groups, and the two groups of clamping structures 120 may be arranged along the second direction. The two groups of clamping structures 120 may respectively clamp the workpiece and take the material, thereby improving the efficiency of taking the material.

[0073] Furthermore, the material picking mechanism 100 may also include a lifting drive structure 140, and the lifting drive structure 140 drives the clamping structure 120 to move along the first direction.

[0074] Specifically, the lifting drive structure 140 may include a lifting drive member 141 and a driving connection member 142. The lifting drive member 141 may be disposed on the frame 110, and the lifting drive member 141 is connected to each group of clamping structures 120 through the driving connection member 142, so that the clamping structures 120 can move simultaneously along the first direction.

[0075] In some embodiments, the lifting drive member 141 may be driven by a screw rod 152 .

[0076] Furthermore, in order to improve the stability of the clamping structure 120 moving along the first direction.

[0077] A second guide member 143 may be provided on the frame 110 , and the driving connection member 142 is slidably connected to the second guide member 143 .

[0078] For example, a plurality of second guide members 143 may be provided. The second guide member 143 may be a guide rod. The driving connecting member 142 may be slidably disposed on the guide rod via a sliding sleeve.

[0079] See also Figure 2The material taking mechanism 100 may further include a position adjustment structure 150, which is drivingly connected to the clamping structure 120 so that the clamping structure 120 can move along the second direction relative to the driving connection member 142. In this way, the position of the clamping structure 120 can be adjusted in the second direction, so that the clamping structure 120 can accurately clamp the workpiece when moving along the first direction.

[0080] Of course, when there are two groups of clamping structures 120, the position adjustment structure 150 can simultaneously drive the two groups of clamping structures 120 to move along the second direction. For example, in some embodiments, the position adjustment structure 150 can drive the two groups of clamping structures 120 to move closer to or farther from each other in the second direction. In other embodiments, the position adjustment structure 150 can drive the two groups of clamping structures 120 to move in the same direction in the second direction.

[0081] Specifically, in some embodiments, the position adjustment structure 150 may include an adjustment driving member 151 , a screw rod 152 , a first screw rod 152 nut, and a second screw rod 152 nut.

[0082] The clamping structures 120 are slidably disposed on the driving connectors 142 and can move along the second direction.

[0083] The screw rod 152 is rotatably arranged on the first driving connection, and the position adjustment driving member 151 is drivingly connected to the screw rod 152 so that the screw rod 152 can rotate. Further, the screw rod 152 may include a first screw rod 152 portion and a second screw rod 152 portion, wherein one group of clamping structures 120 is threadedly connected to the first screw rod 152 portion through the first screw rod 152 nut, and the other group of clamping structures 120 is threadedly connected to the second screw rod 152 portion through the second screw rod 152 nut. In this way, when the screw rod 152 rotates, the two groups of clamping structures 120 can move under the action of the first screw rod 152 nut and the second screw rod 152 nut respectively.

[0084] Optionally, the thread directions of the first screw rod 152 and the second screw rod 152 are opposite. In this way, when the screw rod 152 rotates, the two groups of clamping structures 120 can move closer to or farther from each other in the second direction.

[0085] In some embodiments, the position adjustment drive 151 may be a hand-cranked wheel.

[0086] See also Figure 2 The clamping structure 120 may include a base 121 and a plurality of clamping jaws 122, the base 121 is connected to the driven connecting member 142, and the plurality of clamping jaws 122 are arranged and distributed on the base 121 along a third direction, and the third direction is perpendicular to the first direction and the second direction respectively. This method enables the clamping structure 120 to clamp multiple workpieces at the same time, thereby improving the efficiency of the material taking mechanism 100 in taking materials.

[0087] See also Figure 3 The present application also provides an overhead travelling crane, comprising a base 200, a displacement driving mechanism 300 and the material taking mechanism 100 in the above embodiment. The frame 110 is movably arranged on the base 200, and the displacement driving mechanism 300 drives the frame 110 to move on the base 200, thereby enabling the material taking mechanism 100 to move on the base 200.

[0088] Further, the displacement driving mechanism 300 may include a displacement driving member 310, a gear 320 and a rack 330. The rack 330 is disposed on the base 200, the gear 320 is rotatably disposed on the frame 110 and meshes with the rack 330, and the displacement driving member 310 is drivingly connected to the gear 320 to rotate the gear 320.

[0089] Specifically, when the displacement driving member 310 drives the gear 320 to rotate, the gear 320 can move in the length direction of the rack 330, thereby enabling the frame 110 to move along the length direction of the rack 330, thereby realizing the movement of the material picking mechanism 100.

[0090] For example, in some embodiments, the rack 330 may extend along the third direction, so that the material taking mechanism 100 can move along the third direction.

[0091] Furthermore, in order to facilitate the installation of the displacement driving member 310 and enable the position driving member to simultaneously drive at least two gears 320 to rotate, the displacement driving mechanism 300 further includes a rotating shaft 340, which is rotatably disposed on the frame 110, the gear 320 is connected to the rotating shaft 340, and the displacement driving member 310 drives the rotating shaft 340 to rotate. Among them, a plurality of gears 320 may be disposed on the rotating shaft 340, for example, two gears may be disposed.
