Abstract: A shielding assembly includes a frame including a main body, the main body defining at least one retaining hole; and a cover including a main board, the main panel including retaining elements and rims. The number of the retaining elements is the same as the number of the retaining holes, each rim protruding outwardly from a distal end of one of retaining elements. Each retaining element passes through one of the retaining holes, and each rim is latched with the portions of the frame surrounding the retaining holes.

Abstract: An exemplary film-removing device for removing a protecting film from a workpiece includes a main body and a film-removing mechanism. The film-removing mechanism includes a suspending arm and a roller. The suspending arm has a first end rotatably connected to the main body. The roller is rotatably connected to a second end, opposite to the first end, of the suspending arm. The roller is driven to rotate by movement of the workpiece.

Abstract: An exemplary punch die (30) includes a lower die (40) and an upper die (50). The lower die includes a die core (45), a blank holder (417), and a cylinder (413) disposed in the lower die. The blank holder is disposed on a periphery of the die core. The cylinder is connected to the blank holder and provides a constant force to the blank holder. The upper die includes a punch core corresponding to the die core. A punch machine using the present punch die is also provided.

Abstract: An exemplary flipping apparatus includes a slider, a flipping member and a holding table. The slider is slanted relative to the horizon. A first end of the flipping member is connected to the slider. The flipping member includes a first flipping plate and a second flipping plate facing the first flipping plate. The first flipping plate and the second flipping plate are contoured to define a workplace groove to receive a workpiece to be flipped. An angle defined by the slider and an end section of the first flipping plate opposite to the slider is less than an angle between the slider and the horizon. The holding table is connected to a second end of the flipping member, and the second end is opposite to that of the first end of the flipping member.

Abstract: A transport arm of the present disclosure includes a pneumatic cylinder and an acting arm. The pneumatic cylinder includes a main body, a piston rod, a piston and a guiding pin. A chamber is defined in the main body. The piston rod is partially received in the chamber of the main body. The piston rod defines a guiding groove therein, and a section of the guiding groove is slanted relative to an axis of the piston rod. The piston is fixed to the piston rod and partitions the chamber of the main body into two chambers. The guiding pin is fixed to the main body, and an end of the guiding pin adjacent to the guiding groove of the piston rod moveably engages in the guiding groove. The acting arm is fixed to an end of the piston rod opposite to the piston.

Abstract: An exemplary automatic materials sorting device (100) includes an input belt (11) for transporting materials, a materials sorting mechanism (12), and a control system. The materials sorting mechanism is connected to the input belt, and includes two output belts (121, 122). The input belt and the output belts are configured to transport materials. The control system includes two acting mechanisms (14, 15) and a controller (16). The controller is configured to control the acting mechanisms. The acting mechanisms are capable of creating a force to push the materials to the output belts.
