Technical Field

[0001] The present invention relates to the technical field of keyboards, and in particular to a method for manufacturing keyboard keys. Background Art

[0002] The keyboard is an input device used with a computer. In a laptop computer with a built-in keyboard, it is usually impossible to set a sufficient number of keys while pursuing the diversification of key functions due to the limitation of the overall size. Therefore, a function switch key (such as Capslook, etc.) is set for function keys such as uppercase and lowercase English keys, so that one key can achieve multiple different functions. In order to distinguish whether the function key has switched its function, an LED light is usually designed under the function key, and the switch of the LED light is used to confirm whether the function switch is completed. In the prior art, the function key, that is, the light key with LED, needs to open two sets of molds of different colors during processing to realize the processing and manufacturing of the light key and the ordinary key. Therefore, the light key needs to be produced by a separate mold, which increases the cost of purchasing the mold and prolongs the production cycle, thereby increasing the overall production cost.

[0003] Therefore, how to optimize the production process of light keys and reduce production costs has become a problem that needs to be urgently solved in the industry. Summary of the invention

[0008] According to another embodiment of the present invention, the glue dispensing process is performed on the keyboard key based on the formed part, which specifically includes the steps of: determining whether the keyboard key is a light key; and performing a glue dispensing process on the light key.

[0009] According to another embodiment of the present invention, the glue dispensing process for the light key specifically includes the steps of: confirming the opening position and the number of openings of the light key; and performing a glue dispensing process at the opening position.

[0010] According to another embodiment of the present invention, the opening of the light key is located at an edge of the light key, and the opening is arranged vertically corresponding to the light source, and a cross-sectional shape of the opening covers a cross-sectional shape of the light source.

[0011] According to another embodiment of the present invention, the number of openings on a single light key is 1-10.

[0012] According to another embodiment of the present invention, the design and production of a monochrome keyboard key mold specifically includes the steps of: generating a design model of a keyboard key shape; generating a plurality of continuous bending fitting lines of an outer contour surface of the monochrome keyboard key mold based on the design model of the keyboard key; and forming a model of the monochrome keyboard key mold according to the bending fitting lines;

[0024] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0025] In the description of the present invention, it is to be understood that a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] In order to illustrate the manufacturing method of the keyboard keys provided in the present application, a detailed description is given below in combination with the drawings in the specification and the text description of the embodiments.

[0028] Reference below Figure 1-Figure 5 A method for manufacturing a keyboard key according to an embodiment of the present invention is described as follows: Figure 1 As shown, the method for manufacturing a keyboard key comprises the steps of:

[0029] S100: Design and produce single-color keyboard key molds;

[0030] S200: Injection molding in a single-color keyboard key mold to complete the molding of multiple keyboard keys;

[0031] It should be noted that the parameters and shapes of multiple keyboard keys can be the same or different. For example, multiple keyboard keys can be square letter, number or function keys, or can be long strip enter keys. Alternatively, the long strip keys can be keys of different lengths, such as enter keys and shift keys of different lengths.

[0032] S300: Glue dispensing process based on some keyboard keys after molding.

[0033] It should be noted that by performing glue dispensing on some keyboard keys, it is possible to perform hole opening processing on some keys. For example, a light key needs to have a hole on it to enable the emission of light.

[0034] It can be seen that by processing all the keyboard keys through the same mold, and then processing them separately according to whether the keys need holes, it is possible to use a set of molds for ordinary keyboard keys and light keys at the same time, which can improve production efficiency and reduce production costs.

[0035] According to one embodiment of the present invention, Figure 2 As shown, step S200: injection molding in a single-color keyboard key mold to complete the molding of multiple keyboard keys, specifically including the steps of:

[0036] S210: placing plastic inside the single-color keyboard key mold and heating the plastic;

[0037] S220: Plastic flows inside the single-color keyboard key mold and covers its inner area;

[0038] S230: Cooling until the keyboard keys are formed.

[0039] It can be seen that by processing multiple buttons simultaneously in a designed mold, processing time can be saved and production efficiency can be improved.

[0040] According to one embodiment of the present invention, the interior of a monochrome keyboard key mold includes at least two molding areas of different shapes. For example, according to the keys required for a set of keyboards, seven keys with different parameters such as lengths or shapes are designed. That is to say, by setting different molding areas inside the monochrome keyboard key mold, different types of keys can be processed simultaneously in a set of monochrome keyboard key molds, thereby increasing the production efficiency of the mold.

[0041] According to one embodiment of the present invention, Figure 3 As shown, step S300: performing glue dispensing processing based on some of the keyboard keys after molding, specifically including the steps of:

[0042] S310: Determine whether the keyboard key is a light key;

[0043] It should be noted that the light key refers to a key that is used in conjunction with a light source, that is, the key is a key that can emit light and is light-transmissive.

[0044] S320: Perform glue dispensing process on the light key.

[0045] It should be noted that when it is determined that some of the keys are light keys used in conjunction with a light source, the light keys of this part are subjected to a glue dispensing process so as to open a hole on the key to achieve a light-transmitting effect.

[0046] It can be seen that by distinguishing between ordinary buttons and light keys based on whether holes need to be opened after completing the injection molding process, and then further processing the light keys, it is possible to better process them according to actual needs and improve production efficiency.

[0047] According to one embodiment of the present invention, the opening position of the light key is located at the edge of the light key, and the opening corresponds to the light source setting in the vertical direction, and the cross-sectional pattern of the opening covers the cross-sectional pattern of the light source, that is, the opening on the light key should be able to allow the light source to pass through, therefore, the opening corresponds to the light source setting in the vertical direction, and at the same time, the pattern of the opening in the vertical direction is larger than the pattern of the light source.

[0048] According to one embodiment of the present invention, the number of openings on a single light key is 1-10. For example, only one opening may be set on a single light key, and the opening is set opposite the light source. Alternatively, two openings are set on a single light key and two light sources are set correspondingly at the same time. In this case, one opening corresponds to one light source, so that each light source can transmit light through each opening.

[0049] According to one embodiment of the present invention, Figure 4 As shown, step S100: designing and making a monochrome keyboard key mold, specifically including the steps of:

[0050] S110: Generate a design model of the keyboard key shape;

[0051] S120: generating a plurality of continuous bending fitting lines of the outer contour surface of the monochrome keyboard key mold based on the design model of the keyboard key;

[0052] S130: forming a model of a monochrome keyboard key mold according to the bending fitting line.

[0053] It can be seen that by standardizing the design of the monochrome keyboard key mold model generation method, the design process can be parameterized, normalized and standardized, which greatly improves the efficiency of early mold development and shortens the entire production cycle.

[0054] According to one embodiment of the present invention, Figure 5As shown, step S110: generating a design model of the keyboard key shape, specifically comprising the steps of:

[0055] S111: Based on a preset keyboard key parameterization template, a design model of a mold is generated according to the shape and size of the input keyboard keys.

[0056] It can be seen that the final fit of the mold can be improved by standardizing the design of a monochrome keyboard key mold model generation method based on the keyboard key parameters that need to be produced.

[0057] According to one embodiment of the present invention, the shape and size of the keyboard keys include: key cross-sectional shape, key straight side length and key thickness. That is, by limiting the shape and size of the keyboard keys, a suitable mold can be designed.

[0058] The above-mentioned method for manufacturing keyboard keys provided in the present application is a preferred embodiment and should not be construed as limiting the scope of protection of the present application. Those skilled in the art should be aware that various improvements or replacements may be made without departing from the concept of the present application, and all improvements or replacements should be within the scope of protection of the present application, that is, the scope of protection of the present application should be based on the claims.

[0059] In the absence of conflict, the above embodiments and features in the embodiments may be combined with each other.
