Detailed Description
Fig. 1 is a schematic view of a keyboard according to an embodiment of the invention, fig. 2 is a partially exploded schematic view of the keyboard of fig. 1, and fig. 3 is a schematic view of a key cap of the key of fig. 1. Referring to fig. 1, fig. 2 and fig. 3, the keyboard 100 includes a thin film circuit board 110 and a plurality of keys 120. The membrane circuit board 110 has a plurality of membrane switches 112, and the keys 120 are disposed corresponding to the membrane switches 112, and each key 120 includes a key cap 122 and a scissor-foot 124. The key cap 122 is used to be pressed to conduct the corresponding membrane switch 112, wherein the key cap 122 includes a cap body 125 and a reset piece 126, the cap body 125 and the reset piece 126 are integrally formed, and the scissors 124 are connected between the key cap 122 and the membrane circuit board 110.
Fig. 4 is a schematic view of the cap body 125. Referring to fig. 3 and 4, in the present embodiment, the cap body 125 has an assembling flange 127, and the restoring member 126 has an assembling groove 128, so that the cap body 125 and the restoring member 126 are integrally formed by assembling through the engagement of the assembling flange 127 and the assembling groove 128.
In another embodiment, the cap body 125 and the restoring member 126 may be molded as one body by injection molding or insert molding.
In particular, since the cap body 125 and the reset piece 126 are integrally formed in the present embodiment, the assembling method of the keyboard 100 of the present embodiment is also different from the prior art. Fig. 5 is a schematic diagram illustrating an assembly method of the keyboard 100 of fig. 1. Referring to fig. 2, fig. 3 and fig. 5, in detail, the assembling method of the keyboard 100 of the present embodiment at least includes the following steps: in step S110, a thin film circuit board 110 is provided, wherein the thin film circuit board 110 has a plurality of thin film switches 112; in step S120, a plurality of scissors pins 124 are provided, and the scissors pins 124 are disposed on the film circuit board 110 corresponding to the film switch 112; and step S130, providing a plurality of key caps 122, wherein each key cap 122 includes a cap body 125 and a reset piece 126 formed as a whole, and assembling the key cap 122 to the corresponding scissors 124 corresponding to the membrane switch 112.
In step S130, each key cap 122 includes a cap body 125 and a reset piece 126 which are integrally formed, and further in step S132, an assembling flange 127 is formed on an inner surface 125a of the cap body 125 in advance, an assembling groove 128 is formed on an outer edge of the reset piece 126, and the assembling flange 127 and the assembling groove 128 are engaged with each other to assemble the cap body 125 and the reset piece 126 into one body.
Alternatively, as shown in step S134, the cap body 125 and the reset member 126 are integrally formed by two-shot injection or insert molding.
Then, in step S140, a robot arm (not shown) is used to assemble the plurality of key caps 122 onto the corresponding scissor feet 124 synchronously.
Compared with the existing assembling method of the keyboard, because the reset piece and the scissors are arranged on the film circuit board, the keycap can be well assembled to the reset piece or the scissors after the keycap is aligned with the reset piece and the scissors, and the corresponding film switch can be switched on when the keycap is touched and pressed. If the keycap is aligned with the reset piece but not aligned with the scissors, the assembled keycap can feel the touch of the elastic deformation of the reset piece after being pressed and trigger the membrane switch, but the efficacy of enabling the reset piece to move smoothly and in a balanced manner provided by the scissors is lacked; otherwise, if the keycap is aligned with the scissor feet but not aligned with the resetting piece for assembly, the assembled keycap is pressed and cannot be restored to the original position by the elastic restoring force of the resetting piece. Therefore, it is very difficult for an assembler to assemble the key caps to the return piece and the scissor legs in an automated manner while taking a particular mental effort.
In contrast, the cap body 125 and the reset piece 126 of the present embodiment are already integrally formed, so that when the key cap 122 is assembled to the scissor legs 124, the cap body 125 and the scissor legs 124 only need to be aligned. Therefore, it is easy for an assembler to assemble the key cap 122 to the film wiring board 110. Furthermore, since the alignment assembly process is not complicated, the process can be designed to use a robot to perform an automated assembly process, so that all the key caps 122 of one keyboard 100 can be assembled to the film circuit board 110 simultaneously. Therefore, the assembling personnel can carry out other work which needs more manpower.
Fig. 6 is a schematic view of an electronic device according to the present invention. The aforementioned keyboard 100 is applied to an electronic device 400, wherein the electronic device 400 is, for example, a desktop computer, and the electronic device 400 includes a display 200, the keyboard 100 and a host 300, wherein the display 200 and the keyboard 100 are electrically connected to the host 300.
Fig. 7 is a schematic diagram of a keyboard applied to a notebook computer. Referring to fig. 7, the keyboard 100 may also be applied to a notebook computer. Because the existing notebook computer keyboard needs to be replaced by the whole group or even the whole computer if a single key is damaged, a great deal of cost is consumed for users; by using the keyboard 100 of the present embodiment, the user can replace the individual damaged keys 120. Alternatively, the individual keys 120 that are commonly used may be replaced with a type that meets the hand feeling requirements according to the user's usage requirements. Therefore, the keyboard 100 of the present invention can meet the requirements of the end user.
In addition, since the keyboard of the notebook computer is arranged closely, the key cap 122 can be removed with the aid of the hand tool 210.
In summary, in the assembling method of the keyboard of the present invention, the cap body of the key cap and the reset member are integrally formed and then assembled, so that all the key caps can be synchronously assembled to the scissor legs by using the mechanical arm in the same step. Compared with the prior art, the assembling process can be reduced, and the method is more suitable for automatic assembling.
In addition, in the keyboard and the electronic device using the keyboard, the cap body of the keycap and the reset piece are integrally formed, so that the broken keycap can be conveniently replaced at any time according to requirements, and convenience is brought to detection personnel or terminal users.
Although the present invention has been described with reference to the above embodiments, it should be understood that the invention is not limited to the embodiments, and various changes and modifications can be made by those skilled in the art without departing from the spirit and scope of the invention.
