Description

Technical Field

[0001] The utility model relates to the technical field of computer keyboard part production, in particular to an automatic cutting device for the surplus material of a keycap bracket. Background Technique

[0002] The keycap bracket is a supporting part under the keyboard keycap, which is used to help the keycap perform a stable rotary motion. The existing keycap brackets are all composed of two parts, an outer bracket and an inner bracket. Among them, rotation holes are arranged in the middle of both sides of the outer bracket, and rotating shafts are arranged in the middle of both sides of the inner bracket. The rotating shafts are installed in the rotation holes so that the inner and outer brackets can rotate relative to each other.

[0003] Both the outer bracket and the inner bracket of the keycap bracket are formed by plastic injection molding. During injection molding, in order to improve production efficiency, usually each mold contains multiple cavities. The injection liquid first enters the main runner, and then enters each cavity through the branch runners on both sides respectively. Therefore, the blank parts obtained after injection molding are a whole. Each whole blank part contains multiple workpieces, and the surplus material (generated by the main runner and the branch runners) of each whole blank part needs to be removed manually. After removal, the obtained outer brackets and inner brackets are assembled manually to form the keycap bracket.

[0004] In the related technology, the application number: CN 216885029 U, discloses a device for cutting off the surplus material of the keycap bracket. The device drives the screw to rotate through the operation of the motor. Since the screw is threadedly connected to the screw hole at the upper end of the traction frame, and the sliders at the front and rear ends of the bottom surface of the cutter are respectively slidably connected to the corresponding sliding grooves on the same side of the inner bottom surface of the pressure plate, it can drive the cutter to move leftward to cut off the sprue surplus material on the keycap bracket that is higher than the inner bottom surface of the pressure plate, and quickly and effectively complete the work of cutting off the surplus material. However, during the use of this device, it is not convenient to disassemble the keycap bracket storage tray, which is time-consuming and laborious, resulting in the staff directly operating at the bottom of the cutter, greatly reducing the danger of the device, and the operation space is relatively narrow, which greatly affects the production efficiency of the keycap bracket.
