Description

Technical Field

[0001] The utility model relates to the field of sheet metal processing, in particular to a picker for sheet metal parts. Background Art

[0002] Sheet metal parts are products formed by sheet metal processing technology. Existing sheet metal parts often include two types: blanks and molded parts. Among them, blanks are roughly in the shape of sheets and are easier to grab; molded parts often have different shapes due to different actual needs.

[0003] Existing sheet metal pickers often include a rectangular mounting frame and a plurality of vacuum suction cups arranged on the mounting frame. The vacuum suction cups in this sheet metal picker are dispersedly arranged, which can easily pick up the sheet metal. However, for molded parts of various shapes, such as drawer-shaped molded parts, the vacuum suction cups of the sheet metal picker are not only difficult to extend to the bottom of the molded part to adsorb the molded part, but the dispersed arrangement also makes it difficult to extend the vacuum suction cups into the molded part. The number of vacuum suction cups that can be inserted into the molded part is small, making it difficult to stably pick up the molded part.

[0004] Therefore, this field needs a new technical solution to solve the above problems. Summary of the invention

[0005] In order to improve or solve the technical problem that sheet metal pickers in the prior art are difficult to stably pick up molded parts, the utility model provides a picker for sheet metal parts. The picker includes: a mounting frame, suitable for mounting on a robot, and including a first side and a second side opposite to each other; a first adsorption assembly, arranged on the first side, and including a plurality of first suction cups that are dispersed and arranged and facing away from the first side; a second adsorption assembly, arranged on the second side, and including a plurality of extension rods mounted on the second side, and a plurality of second suction cups mounted on the extension rods; the second suction cups are mounted on the end of the extension rod away from the second side, and close to the middle position of the mounting frame.

[0006] In the picker for sheet metal parts of the utility model, a mounting frame, a first adsorption assembly and a second adsorption assembly are included. The mounting frame includes a first side surface and a second side surface opposite to each other, the first adsorption assembly is arranged on the first side surface, and the second adsorption assembly is arranged on the second side surface; the first adsorption assembly includes a plurality of dispersedly arranged first suction cups, which can conveniently pick up the sheet metal; the second adsorption assembly includes a plurality of extension rods and a plurality of second suction cups, one end of the extension rod is away from the second side surface, and the second suction cup is installed on the end of the extension rod away from the second side surface, so that the second suction cup can better extend into the interior of the molded part, adsorb the bottom of the molded part, and conveniently pick up the molded part; at the same time, the plurality of second suction cups are close to the middle position of the mounting frame, so that the second suction cups are arranged more densely, and more second suction cups can be extended into the molded part, so that the molded part can be picked up more stably. When it is necessary to pick up the sheet metal, the first side surface of the mounting frame is facing the sheet metal, that is, the first adsorption assembly is used to pick up the sheet metal; when it is necessary to pick up the molded part, the second side surface of the mounting frame is facing the molded part, that is, the second adsorption assembly is used to pick up the molded part. Through the above arrangement, the picker for sheet metal parts of the utility model can not only pick up the material pieces more conveniently, but also pick up the formed parts more conveniently and stably, thus better meeting the production requirements of automatic loading and unloading of sheet metal parts.

[0007] In the preferred technical solution of the picker for sheet metal parts, the extension rod extends obliquely in a direction away from the second side surface and toward the middle position of the mounting frame. Through the above arrangement, the obliquely extended extension rod can make the second suction cups gather toward the middle position of the mounting frame, so that more second suction cups extend into the molded part, thereby improving the picking stability of the molded part.

[0008] In the preferred technical solution of the picker for sheet metal parts, the mounting frame includes: a connecting seat, suitable for connecting with the robot; a first support, fixedly connected with the connecting seat, and the first side is located on the first support; a second support, fixedly connected with the connecting seat, and arranged side by side with the first support, and the second side is located on the second support. Through the above arrangement, the first support and the second support are arranged side by side, so that the first adsorption component on the first support and the second adsorption component on the second support do not affect each other, the positions of the first suction cup and the second suction cup can be freely arranged, and it is possible to realize the picking of multiple varieties and models of sheets and molded parts, thereby improving the scope of application of the picker.

[0009] In the preferred technical solution of the picker for sheet metal parts, a fixing member is arranged between the first support and the second support to fix the two. Through the above arrangement, the fixing member can not only improve the connection stability between the first support and the second support, but also improve the overall stability of the mounting frame, thereby preventing the first support and the second support from shaking significantly during the movement of the mounting frame.

[0010] In the preferred technical solution of the picker for sheet metal parts, the second support includes a second main pipe, a second fixing seat connecting the second main pipe and the connecting seat, and a second branch pipe fixed to the second main pipe; the second branch pipe and the second main pipe are arranged alternately. Through the above arrangement, the second main pipe and the second branch pipe are arranged alternately, which can simplify the structure of the second support, reduce the weight of the second support, and reduce the energy loss required for the movement of the mounting frame.

Through the above arrangement, the transfer block is sleeved on the outside of the second branch pipe, so that the transfer block can slide along the length direction of the second branch pipe and rotate along the circumference of the second branch pipe, so as to facilitate the adjustment of the position of the second suction cup to use different varieties and models of molded parts.

[0012] In the preferred technical solution of the above-mentioned picker for sheet metal parts, a bus valve island is arranged on the mounting frame, and the bus valve island is connected to any of the first suction cups and any of the second suction cups, and is configured to independently control the suction state of any of the first suction cups and any of the second suction cups. Through the above-mentioned setting, the bus valve island can independently control the suction state of any of the first suction cups and the second suction cups, so that the picker can freely control the suction state of the corresponding suction cups according to the structural size of the sheet or the molded part, avoid empty suction, and reduce energy loss.

[0013] In the preferred technical solution of the picker for sheet metal parts, pressure sensors are arranged on the first suction cup and the second suction cup. Through the above arrangement, the pressure sensors can detect whether the suction cup picks up the sheet metal part, thereby ensuring the accuracy and effectiveness of picking up.

[0014] In the preferred technical solution of the picker for sheet metal parts, an oil injector is also arranged on the mounting frame. Through the above arrangement, the oil injection of the sheet metal parts can be realized by adjusting the position and angle of the mounting frame, making the oil injection process more flexible.

[0015] In the preferred technical solution of the picker for sheet metal parts, an oil injection fixing seat is arranged between the oil injector and the mounting frame, and the oil injection fixing seat is adjustably mounted on the mounting frame. Through the above arrangement, the oil injection fixing seat can adjust the angle and position of the oil injector, so as to facilitate oil injection on the workpiece.
