The embodiment of the present application further provides a deviation detecting method, which uses the jig 10 for deviation detection to perform deviation detection on a product, that is, a mobile phone display screen 1000, specifically, please refer to fig. 15 and fig. 16 in combination, and the deviation detecting method includes the following steps:
s101, positioning the jig, and abutting the jig 10 for deviation detection in the foregoing embodiment against the outline edge of the product to be detected, i.e. the outline edge of the mobile phone display screen 1000. Specifically, the baffle positioning surface 103 of the jig abuts against the outer edge of the cover glass 80 to position the jig 10;
s102, product crimping, namely, covering and pressing the detection plate 200 of the jig 10 on the product to be detected in deviation and the FPC60, specifically, crimping the detection part 202 of the detection plate and the FPC 60.
S103, confirming the deviation, namely confirming the deviation of the FPC60, which is a product to be detected, specifically, confirming whether the FPC60 deviates from the cover glass 80 according to the pressure contact between the detection portion 202 and the FPC.
Further, in step S103, confirming the misalignment of the FPC60 includes the steps of:
s1031, when the side of the FPC60 close to the first detection edge 2021 is far away from the first detection edge 2021 and the second detection edge 2022, the FPC60 is deviated from the over-range relative to the cover glass 80;
s1032 and FPC60 are not displaced beyond the range with respect to cover glass 80 when the side of FPC60 adjacent to first detection edge 2021 is between first detection edge 2021 and second detection edge 2022.
In the embodiment of the present application, when step S103 is executed, a visual method may be adopted to determine whether the FPC60 is offset with respect to the cover glass 80. Referring to fig. 17, it is visually confirmed whether the edge of the right side 601 of the FPC60 is located between the first detection edge 2021 and the second detection edge 2022 for corresponding confirmation.
Specifically, if the right side 601 is located between the first detection edge 2021 and the second detection edge 2022, the FPC60 is not displaced beyond the range with respect to the cover glass 80; if the right side 601 is not located between the first detection section 2021 and the second detection section 2022, the FPC60 is displaced out of the range with respect to the cover glass 80. The directional indication in the embodiment of the present application, for example, "right" in "right side" is merely used to explain the relative positional relationship between the respective members in the orientation shown in fig. 17, and if the specific posture is changed, the directional indication is changed accordingly.
In the embodiment of the present application, when step S103 is executed, a corresponding method can be adopted to confirm whether the FPC60 is offset with respect to the cover glass 80. Referring to fig. 18, when the jig 10 is covered and pressed on the FPC60, the FPC60 may correspond to three relative positions L1, L2, and L3 with respect to the jig 10, wherein the position LI is flush with the lower edge of the jig 10, the position L3 is flush with the upper edge of the jig 10, and the position L20 is flush with the gap offset of the jig 10. The method of confirming whether the FPC60 is misaligned with respect to the cover glass 80 by manually pulling up the FPC60 is to pull up the FPC60 from the top to the bottom and confirm whether the FPC60 can be stopped when pulled to a certain position.
Specifically, if the FPC60 is pulled up from the top, the portion below the position L1 can be pulled up, and the FPC60 is deviated beyond the range with respect to the cover glass 80, that is, the left deviation is often out of the limit; if the FPC60 is pulled up from top to bottom and can be stopped when pulled to the position L2, the deviation of the FPC60 with respect to the cover glass 80 does not exceed the range, that is, the FPC60 is located in the range of left and right deviation; if the FPC60 is pulled up from the top down, the FPC60 is not pulled up until the position L3 is stopped, that is, the position L3 or less, and the FPC60 is deviated from the cover glass beyond the range, that is, the right deviation is often out of the limit. It should be noted that the directional indications (up, down, left, and right …) in the embodiment of the present application, for example, "right" in "right side" is merely used to explain the relative positional relationship between the components in the orientation shown in fig. 18, and if the specific posture is changed, the directional indication is changed accordingly.
The above description is only a part of the embodiments of the present application, and not intended to limit the scope of the present application, and all equivalent devices or equivalent processes performed by the content of the present application and the attached drawings, or directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
