Description

Technical Field

[0001] The invention relates to the technical field of milk powder can assembly, and in particular to an automatic material taking device. Background Art

[0002] The milk powder cap is the lid of the milk powder can. The milk powder cap has an upper cover and a lower cover. When the milk powder cap is produced by injection molding, the upper and lower covers are not fastened together. In order to meet the requirements of the next assembly process, the upper and lower covers of the milk powder cap need to be fastened together. After fastening, the milk powder cap is installed as a whole on the milk powder can to form a whole milk powder can.

[0003] Due to the irregular shape of milk powder cans, such as Figure 1 As shown, the grippers used in the prior art are unable to effectively grasp the caps. Currently, manual assembly is often used to assemble the milk powder caps onto the cans, which is inefficient. A small amount of automated assembly equipment has also appeared on the market, but the grippers used by these devices often cause the caps to loosen after being removed from the cans, thus affecting the subsequent assembly process. The challenge we need to address is how to provide a device that can effectively grasp the caps and prevent them from loosening when moved to the assembly station. Summary of the Invention

[0004] The object of the present invention is to provide an automatic material taking device to solve the problem of unstable grabbing of milk powder caps in the prior art.

[0005] To achieve the above object, the present invention is implemented by adopting the following technical solutions:

In the first position, the pressing rod is located above the connecting seat to press the product sucked in the connecting seat. In the second position, the height of the pressing rod is lower than the height of the working end of the suction cup assembly.

[0011] Furthermore, the connecting seat includes at least two arc-shaped connecting blocks, and the multiple arc-shaped connecting blocks are on the same circular ring; the connecting surfaces of the arc-shaped connecting blocks are stepped.

[0017] Furthermore, a limiting rod is provided on the auxiliary connecting frame, and a limiting cylinder is connected to the mounting plate; in the first position, the output end of the limiting cylinder presses the limiting rod.

[0018] This design further ensures the pressing effect on the milk seal cap, prevents the problem of unstable suction of the milk powder cap caused by the failure of the rotating shaft and free rotation.

[0019] Furthermore, two symmetrical mounting plates are connected to the supporting main board, each mounting plate is connected to a material pressing mechanism and two symmetrical material suction mechanisms, and each material pressing mechanism is provided with two pressing rods.

[0020] The two mounting plates provide four suction mechanisms, which can suck and take out four milk powder caps at a time, thereby improving the efficiency of taking out materials.

[0021] Furthermore, the rotating shaft is rotatably connected to the bottom surface of the mounting plate via a connecting plate, and a servo motor for driving the rotating shaft to rotate is connected to the connecting plate on one side.

[0022] Furthermore, it also includes a limiting roller, which is located on one side of the connecting seat and is connected to the supporting main board through a telescopic cylinder.

[0037] In the present application, in order to ensure the effect of grabbing the milk powder cover, the suction disc assembly 32 is specially designed, which can better adapt to the milk powder cover than the conventional gripper, and the suction disc in the suction disc assembly 32 can suck the plane in the cover body of the milk powder cover, which can well suck the milk powder cover.

[0038] Further, the connecting seat 31 is designed on the outer periphery of the suction disc assembly 32, which can play a role in holding the outer periphery of the milk powder cover when the suction disc assembly sucks the milk powder cover. Specifically, the connecting surface on the inner side of the connecting seat 31 is designed in a stepped shape to adapt to the shape of the top surface of the milk powder cover and achieve the effect of holding the milk powder cover.
