For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0016] See also Figure 1 A manipulator material picking device includes a moving plate 10 connected to an external moving mechanism, two clamping plates 20 installed under the moving plate 10 for clamping objects, a first driving unit 30 connected to the two clamping plates 20 for driving the two clamping plates 20 to move closer to or away from each other, a support plate 50 installed on the side where the two clamping plates 20 are away from each other, and a second driving unit 40 connected to the support plate 50 for driving the support plate 50 to move to the bottom between the two clamping plates 20 and return from the bottom between the two clamping plates 20 to the side where the two clamping plates 20 are away from each other.

[0017] Specifically, in the present embodiment, when working, the external moving mechanism moves the moving plate 10 so that the object is located between the two clamping plates 20, and then the first driving unit 30 drives the two clamping plates 20 to approach each other and clamp the object. After the clamping is completed, the moving mechanism then moves the clamping plate 20 away from the storage table for placing the object through the moving plate 10. After moving a certain distance, the second driving unit 40 drives the support plate 50 to move to the bottom between the two clamping plates 20 to support the object and prevent the object from falling off from under the two clamping plates 20, thereby ensuring the stability of the object during transfer. When the object is about to move to the preset position, the second driving unit 40 drives the support plate 50 to reset first, and then the external moving mechanism continues to drive the clamping plate 20 to move to the final position through the moving plate 10, and then the first driving unit 30 drives the two clamping plates 20 away from each other, thereby releasing the object. At this time, the moving process of one object is completed.

[0018] The utility model relates to a manipulator material picking device, which prevents objects from falling off from under the two clamping plates 20 by arranging a moving plate 10, a clamping plate 20, a first drive unit 30, a second drive unit 40 and a support plate 50, thereby ensuring the stability of the objects during transfer, and is suitable for industrial applications.

[0019] In a specific embodiment, the first drive unit 30 includes a screw (not shown in the figure) and a servo motor 301; the screw is installed at the bottom of the moving plate 10, and the screw is provided with threaded sections at opposite ends; the two clamps 20 are respectively installed on the two threaded sections; the servo motor 301 is installed on the side of the moving plate 10 and is connected to the screw to drive the screw to rotate. In this embodiment, the servo motor 301 and the two reverse threads on the screw are set to effectively drive the two clamps 20 to move away from or close to each other as needed. Furthermore, the first drive unit 30 also includes a connecting block; a first mounting groove (not shown in the figure) is provided at the bottom of the moving plate 10; the screw is installed in the first mounting groove; the clamp 20 is connected to the screw through a connecting block (not shown in the figure).

[0020] In a specific embodiment, the second driving unit 40 includes a connecting plate 401, a power cylinder 402, a first connecting rod 403, a second connecting rod 404, a third connecting rod 405, a transmission gear 406, a first bevel gear 407 and a second bevel gear 408; the connecting plate 401 is installed on the side of the two clamping plates 20 away from each other; the power cylinder 402 is installed on the connecting plate 401; the first connecting rod 403 is vertically installed below the connecting plate 401 and is connected to the power cylinder 402; a second mounting groove 201 is provided on the side of the clamping plate 20 close to the first connecting rod 403; the second mounting groove A rack 202 is provided on the side wall of 201; the second connecting rod 404 is perpendicular to the first connecting rod 403, and one end thereof passes through the first connecting rod 403 and is located in the second mounting groove 201; the transmission gear 406 is installed in the second mounting groove 201, and is connected to the second connecting rod 404, and meshes with the rack 202; the third connecting rod 405 is rotatably installed on the lower end of the first connecting rod 403, and its bottom is connected to the support plate 50; the first bevel gear 407 is installed on the second connecting rod 404; the second bevel gear 408 is installed on the third connecting rod 405, and meshes with the first bevel gear 407.

[0021] Specifically, in this embodiment, when the support plate 50 needs to be moved to the lower part between the two clamping plates 20 during operation, the power cylinder 402 drives the first connecting rod 403 to move downward, thereby driving the second connecting rod 404 and the third connecting rod 405 connected to the first connecting rod 403 to move downward. When the second connecting rod 404 moves downward, the transmission gear 406 meshes with the rack 202, thereby driving the second connecting rod 404 to rotate, thereby driving the first bevel gear 407 to rotate, thereby driving the second bevel gear 408 to rotate, thereby driving the third connecting rod 405 to rotate, thereby driving the support plate 50 to rotate to the lower part between the two clamping plates 20; at the same time, since the first connecting rod 403 also drives the third connecting rod 405 to move downward, it can effectively avoid the interference between the support plate 50 and the clamping plates 20 when rotating. In this embodiment, through the setting of a power source, that is, the power cylinder 402, the lifting and rotation of the support plate 50 can be effectively driven, which greatly saves the device cost.

[0022] In a specific embodiment, a side of the clamping plate 20 is provided with a cushioning cotton. In this embodiment, the cushioning cotton can effectively reduce the damage to the object during clamping.

[0023] The utility model relates to a manipulator material picking device, which prevents objects from falling off from under the two clamping plates 20 by arranging a moving plate 10, a clamping plate 20, a first drive unit 30, a second drive unit 40 and a support plate 50, thereby ensuring the stability of the objects during transfer, and is suitable for industrial applications.

[0024] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
