[0069] Embodiment one

[0070] As Figures 1 to 4As shown, and based on the foregoing, the key 120 and the flat cable plate 130 can be assembled to the outside and the inside of the shell 110, respectively, and the assembly surface of the key 120 is parallel to the assembly surface of the flat cable plate 130. The flat cable plate 130 is provided with a mounting groove 131. The key 120 and the flat cable plate 130 are supported by a support (not shown in the figure). The support is provided with a protruding portion. The protruding portion of the support can extend into the mounting groove 131 and abut to the groove bottom of the mounting groove 131. That is, the support between the key 120 and the flat cable plate 130 can abut between the side of the key 120 facing the inside of the shell 110 and the groove bottom of the mounting groove 131. Due to the machining error in the manufacturing process, the distance between the assembly surface of the key 120 and the assembly surface of the flat cable plate 130, the size of the key 120, and / or the depth of the mounting groove 131 of the flat cable plate 130 on different shells 110 can be different, which can cause the distance between the key 120 and the flat cable plate 130 and the groove bottom of the mounting groove 131 assembled on different shells 110 along the arrangement direction of the key 120 and the flat cable plate to be different. If the size of the support assembled on different shells 110 is the same, the size of the support assembled on the shell 110 can be too large or too small. If the size of the support is too large, the assembled key 120 can protrude outwardly from the shell 110 and / or the flat cable plate 130 can protrude inwardly from the shell 110. If the size of the support is too small, there can be a gap between the key 120 and the support and / or between the flat cable plate 130 and the support after assembly, which can cause the key 120 and the flat cable plate 130 to be unable to be effectively supported. Therefore, a support with an appropriate size needs to be selected according to the distance between the key 120 and the flat cable plate 130 and the groove bottom of the mounting groove 131 along the arrangement direction of the key 120 and the flat cable plate.

[0071] To this end, please refer to Figure 5 The embodiment provides a selection method of a support assembled between the key 120 and the flat cable plate 130. The selection method of the support assembled between the key 120 and the flat cable plate 130 comprises the following steps.

[0072] Assembling the flat cable plate 130 to the inside of the shell 110. Selecting a first plane 112 parallel to the assembly surface of the key 120 on the outer wall of the shell 110. Detecting the distance between the first plane 112 and the groove bottom of the mounting groove 131 along the direction perpendicular to the first plane 112 and obtaining a first detection value.

[0073] Selecting a second plane 113 parallel to the assembly surface of the flat cable plate 130 on the inner wall of the shell 110. Detecting the distance between the first plane 112 and the second plane 113 along the direction perpendicular to the first plane 112 and obtaining a second detection value.

[0074] Assemble the key 120 to the shell 110, obtain the second plane 113 and the interval of the side of the key 120 facing the inside of the shell 110 along the direction perpendicular to the first plane 112, and obtain a third detection value;

[0075] Obtain the difference between the second detection value and the third detection value, subtract the difference from the first detection value, and obtain a target detection value;

[0076] According to the target detection value, set the size of the support, and select the support according to the set size.

[0077] In the embodiment, by obtaining the second detection value and the third detection value, the interval of the side of the key 120 facing the inside of the shell 110 along the direction perpendicular to the first plane 112 is obtained by calculating the difference between the second detection value and the third detection value. Then, by subtracting the difference from the first detection value, the interval of the side of the key 120 facing the inside of the shell 110 along the direction perpendicular to the first plane 112 and the interval of the bottom of the mounting groove 131 of the flat cable plate 130 along the direction perpendicular to the first plane 112 when the support is not assembled are obtained. Then, according to the interval, the support is selected, so that the selected support can abut between the side of the key 120 facing the inside of the shell 110 and the bottom of the mounting groove 131, i.e. there is no gap between the key 120 and the support and between the flat cable plate 130 and the support after assembly, so as to ensure that the key 120 and the flat cable plate 130 can be effectively supported, and at the same time, it can also be ensured that the support will not exert pressure on the key 120 and / or the flat cable plate 130 in a natural state, i.e. the key 120 will not protrude outwardly from the shell 110 after assembly, and the flat cable plate 130 will not protrude inwardly from the shell 110, thereby ensuring that the quality of the electronic product meets the requirements.

In order to detect the interval of the side of the key 120 facing the inside of the shell 110 along the direction perpendicular to the first plane 112 and the interval of the bottom of the mounting groove 131 of the flat cable plate 130 along the direction perpendicular to the first plane 112 when the support is not assembled, please refer to Figures 1 to 4 and Figures 6 to 17The embodiment also provides a detection device, which comprises the first detection device 310, the second detection device 320 and the third detection device 330.

The second probe 321 and the third probe 322 are used to detect the distance between the first plane 112 and the second plane 113 in a direction perpendicular to the first plane 112. The fourth probe 331 is used to detect the distance between the second plane 113 and the side of the key 120 facing the inside of the shell 110 in a direction perpendicular to the first plane 112, so as to detect the distance between the side of the key 120 assembled on the shell 110 and the bottom of the mounting groove 131 of the flat cable plate 130 assembled on the shell 110 in a direction perpendicular to the first plane 112 when the support is not assembled, and select the support according to the distance, so as to ensure that there is no gap between the key 120 and the support and between the flat cable plate 130 and the support after assembly, so as to ensure that the key 120 and the flat cable plate 130 can be effectively supported, and meanwhile, the support does not exert pressure on the key 120 and / or the flat cable plate 130 in a natural state, i.e., the key 120 does not protrude towards the outside of the shell 110 after assembly, and the flat cable plate 130 does not protrude towards the inside of the shell 110, thereby ensuring that the quality of the electronic product meets the requirements.
