Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; the two elements may be directly connected or indirectly connected through an intermediate medium, or may be communicated with each other inside the two elements, or may be wirelessly connected or wired connected. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
The embodiment of the invention discloses a water gap hot cutting process of keyboard keys, which comprises the following steps as shown in figures 1 and 2:
step S101, mounting a prefabricated integrated keyboard key 2 on a hot cutting die 1;
step S102, heating a hot cutting head 3 for hot cutting the integrated keyboard keys 2 to a preset temperature;
step S103, performing hot cutting on the integrated keyboard keys 2 for a preset time through the hot cutting head 3 to obtain the independent keyboard keys 2.
It should be noted that in the gate hot cutting process of the keyboard key disclosed in the embodiment of the present invention, the prefabricated integrated keyboard key 2 is installed on the hot cutting mold 1; heating a hot cutting head 3 for hot cutting the integrated keyboard keys 2 to a preset temperature; and carrying out hot cutting on the integrated keyboard keys 2 for preset time through the hot cutting head 3 to obtain independent keyboard keys. Compared with the prior art, the method can quickly acquire the independent keyboard keys, avoids secondary processing of the keyboard keys, and further improves the production efficiency of the keyboard.
In an alternative embodiment, the integrated keyboard key 2 is integrally formed by injection molding. Through the integrated into one piece that moulds plastics, processing out the keyboard button that can be quick improves the production efficiency of keyboard.
In an alternative embodiment, the preset temperature is 60-80 ℃. In this embodiment, through suitable temperature of predetermineeing, make integrative keyboard button 2 soften, make things convenient for hot crop 3 to carry out hot cutting to the mouth of a river of keyboard button 2.
In an optional embodiment, the preset time is 1.5-3 s. It should be noted that the hot cutting time of the hot cutting head 3 is too long, so that the hot cutting head 3 may damage the keyboard keys 2; the hot cutting time of the hot cutting head 3 is too short, so that the softening degree of the hot cutting head 3 to the keyboard is insufficient, the punching of the hot cutting head 3 is influenced, and the product yield of the keyboard keys 2 is further influenced. Because the preset time is 1.5-3 s, the keyboard can be conveniently and rapidly hot-cut by the hot cutting head 3, and the production efficiency and the product yield of the keyboard are improved.
In an alternative embodiment, the distance between the hot cutting head 3 and the glue inlet of the integrated keyboard key 2 is less than or equal to 0.06 mm. The smaller the distance between the hot cutting head 3 and the glue inlet of the integrated keyboard key 2 is, the more easily the water inlet of the keyboard key 2 is cut off by the hot cutting head, and the hot cutting efficiency of the hot cutting head 3 is improved.
In an alternative embodiment, the hot cutting head is provided with hot cutting power by an air cylinder. It should be noted that the hot cutting head 3 is driven by the cylinder to contact the keyboard, and then the key water gap is hot cut.
In an alternative embodiment, the hot-cutting pressure of the air cylinder is 0.4-0.8 MPa. It should be noted that, because the hot-cutting pressure of the cylinder is 0.4-0.8 MPa, the cylinder can conveniently and stably control the hot-cutting head 3 to move, and the hot-cutting head is driven to perform hot-cutting on the water gap of the keyboard key 2.
The working principle is as follows: the embodiment of the invention discloses a water gap hot cutting process of keyboard keys, which is characterized in that a prefabricated integrated keyboard key 2 is arranged on a hot cutting die 1; heating a hot cutting head 3 for hot cutting the integrated keyboard keys 2 to a preset temperature; and carrying out hot cutting on the integrated keyboard keys 2 for preset time through the hot cutting head 3 to obtain the independent keyboard keys 2. Compared with the prior art, the method can quickly acquire the independent keyboard keys, avoids secondary processing of the keyboard keys, and further improves the production efficiency of the keyboard.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments.
