The long side of the outer contour of the electronic device cover 20 is defined as a first direction X, and a second direction Y perpendicular to the first direction.

Referring to fig. 2 and 3, fig. 3 is a schematic structural diagram illustrating an installation structure of a cover 20 and a lens 50 of an electronic device according to an embodiment of the present application. Specifically, at least one first fitting hole 2110 is formed in the bezel 210, and at least one second fitting hole 510 corresponding to the first fitting hole 2110 is formed in the lens 50. The bezel 210 is used to mount the lens 50, and the first fitting holes 2110 on the bezel 210 correspond to the second fitting holes 510 of the lens 50. Here, in the present application, the number of the first fitting holes 2110 and the second fitting holes 510 is three. Referring to fig. 4, fig. 5 and fig. 6, fig. 4 is a partial schematic view of a state where the decorative ring 210 and the lens 50 are installed according to an embodiment of the present application, fig. 5 is a partial schematic view of another state where the decorative ring 210 and the lens 50 are installed, fig. 6 is a partial schematic view of another state where the decorative ring 210 and the lens 50 are installed, a center of a second matching hole 510 in the lens 50 in fig. 4 coincides with a center of a first matching hole 2110 in the decorative ring 210, a center of a second matching hole 510 in fig. 5 deviates from a center of a first matching hole 2110 in the decorative ring 210, and an included angle between a connecting line of centers of three second matching holes 510 and a connecting line of centers of three first matching holes 2110 is an acute angle. Fig. 6 is a partial schematic view of another state of mounting the bezel 210 and the lens 50, in which the line of centers of the three second fitting holes 510 is collinear with the line of centers of the three first fitting holes 2110, but the centers of the three second fitting holes 510 are offset from the centers of the three first fitting holes 2110 in the second direction. It is understood that, in other embodiments, the number of the first fitting holes 2110 and the second fitting holes 510 may also be 1, 2, or 4, and the like, which is not limited herein, and three are illustrated in the embodiments of the present application.

Referring to fig. 7, fig. 7 is a partial projection view of the bezel 210 and the electronic device cover 20. It can be understood that, for the principle between the two second fitting holes 510 of the lens is consistent with the principle of the two first fitting holes 2110 of the decorative ring 210, that is, a line connecting the centers of the two first fitting holes 2110 or the two second fitting holes 510 forms an included angle with the first direction or the second direction, corresponding to the included angle B, and the projection distance between the centers of the two centers of the circles in the first direction or the second direction is a1, it can be understood that the projection distance between the centers of the two first fitting holes 2110 or the two second fitting holes 510 in the first direction or the second direction corresponds to the distance between the electronic device cover 20 and the decorative ring 210 or the distance between the lens 50 and the electronic device cover 20.

Referring to fig. 8, fig. 8 is a schematic structural diagram of the first detecting element 410 detecting a viewing angle of the electronic device cover 20 according to an embodiment of the present disclosure. The detecting assembly 40 includes a first detecting member 410, the first detecting member 410 includes a first photographing assembly 4110, the first photographing assembly 4110 includes a first camera 4112 and a first light source element 4114, the first camera 4112 is disposed above the electronic device cover 20 and faces the electronic device cover 20; the first light source assembly is disposed below the electronic device cover 20 and faces the electronic device cover 20. When the electronic device cover 20 reaches the preset detection area, the first detection part 410 is required to detect the rotation angle of the bezel 210 on the electronic device cover 20 relative to the electronic device cover 20. Wherein, the connection line of the circle centers of the three first matching holes 2110 on the preset decoration ring 210 is parallel to the second direction and is perpendicular to the first direction, in an embodiment of the present application, an included angle between a connection line of circle centers of the three first matching holes 2110 of the bezel 210 and the second direction is a rotation angle of the bezel 210 relative to the electronic device cover 20, that is, the first light source element 4114 is turned on, the first photographing component 4110 obtains the first image, since light is emitted from the bottom of the bezel 210 to the top of the electronic device cover 20, so that the bezel 210, except for the first fitting hole 2110, is light-transmissive, and the other parts are dark, the first image obtained by the first photographing component 4110 corresponds to the image information of the three first matching holes 2110, and is connected to the circle centers of the three first matching holes 2110 to compare with the first direction or the second direction, so as to obtain the rotation angle of the bezel 210 on the electronic device cover 20 relative to the electronic device cover 20.

Referring to fig. 9, fig. 9 is a schematic structural diagram of the second detecting element 420 detecting a viewing angle of the lens 50 according to an embodiment of the present disclosure. The detecting assembly 40 further includes a second detecting member 420, the second detecting member 420 includes a second photographing assembly 4210, the second photographing assembly 4210 includes a second camera 4212 and a second light source element 4214, and the second camera 4212 and the second light source element 4214 are both disposed below the electronic device cover 20 and face the lens 50. In an embodiment of the present application, the second detecting element 420 is used for detecting whether the assembling error of the lens 50 exceeds a threshold value. It can be understood that, when the lens 50 is installed on the lens installation assembly 30, the angles of the lens 50 captured are different, so that the deflection angle of the lens 50 compared with the electronic device cover 20 when captured needs to be detected, and further the deflection angle of the bezel 210 relative to the electronic device cover 20 is eliminated, so that the lens 50 and the bezel 210 can be accurately installed. The second light source assembly is opened, the second camera 4212 obtains a second image, and since the lens 50 is not transparent except the second matching hole 510, the second camera 4212 can obtain the size information of the three second matching holes 510, and further connect the circle centers of the three second matching holes 510 to obtain the deflection angles between the three second matching holes 510 and the electronic device cover body 20, and further control the manipulator for grabbing the lens 50 to deflect the corresponding angle to match with the decoration ring 210.

It is understood that, after the lens 50 is mounted on the bezel 210, the offset distance of the lens 50 on the battery cover assembly 310 relative to the electronic device cover 20 can be detected by the first detecting member 410. After the lens 50 and the bezel 210 are assembled, the mounted battery cover assembly 310 needs to be rechecked by using the first detecting element 410, specifically, the offset distance of the mounted lens 50 relative to the electronic device cover 20 is detected. By turning on the first light source element 4114, the size of the second fitting hole 510 of the lens 50 is smaller than that of the first fitting hole 2110 on the bezel 210, so when the first light source element 4114 is turned on, a light source passes through the second fitting hole 510 from the first fitting hole 2110, and the first camera 4112 can obtain complete size information of three second fitting holes 510 or complete size information of three second fitting holes 510 and size information of a part of the first fitting hole 2110. At this time, from the perspective of camera shooting, if the center of the first fitting hole 2110 is close to or the same as the center of the second fitting hole 510, so that the outer circumference of the first fitting hole 2110 is completely shielded by the lens 50 outside the first fitting hole 2110, the first camera 4112 obtains three complete pieces of size information of the second fitting hole 510; on the contrary, if the deviation of the lens 50 is large, so that the centers of the first matching hole 2110 and the second matching hole 510 are far apart, the first camera 4112 can obtain the size information of a part of the first matching hole 2110, but can obtain the full size information of the second matching hole 510. The center of the circle connecting the three second fitting holes 510 is opposite to the first direction or the second direction of the electronic device cover 20, so that the deflection angle of the lens 50 relative to the electronic device cover 20 can be obtained.

Referring to fig. 10 and 11, fig. 10 is a schematic structural view of a third detecting element 430 according to an embodiment of the present application, and fig. 11 is a schematic structural view of a point inspection jig 60 detected by the third detecting element 430 shown in fig. 6. The inspection jig 60 further includes a detection cover 610 having a size consistent with that of the cover 20 of the electronic device, and a detection ring 6110 having a size consistent with that of the outer periphery of the decorative ring 210, where the detection ring 6110 includes at least one detection hole 6112, and the detection hole 6112 corresponds to the second matching hole 510; wherein the size of the at least one detection hole 6112 is smaller than the size of the second mating hole 510. It can be understood that the spot inspection jig 60 is used for detecting the offset distance between the centers of the second fitting hole 510 on the lens 50 and the first fitting hole 2110 on the decorative ring 210 during the process of installing the decorative ring 210 on the lens 50. The dimensions of the detection cover 610 and the detection ring 6110 are consistent with those of the electronic device cover 20 and the decorative ring 210, so that other unnecessary errors caused by different jigs can be avoided. Among them, in an embodiment of the present application, the number of the detecting holes 6112 is three, which is consistent with the number of the first fitting holes 2110. And the detection hole 6112 in the middle has a size smaller than the first fitting hole 2110 in the middle.

Referring to fig. 12, 13 to 14, fig. 12 is a front view of the point inspection jig 60, fig. 13 is an exploded structural schematic view of the point inspection jig 60 and the lens 50, and fig. 14 is a structural schematic view of the point inspection jig 60 and the lens 50 after being mounted. It can be derived that the detecting assembly 40 further includes a third detecting element 430, the third detecting element 430 includes a third photographing element 4310, the third photographing element 4310 includes a third camera 4312, a third light source element 4314 and a fourth light source element 4316, the third camera 4312 and the third light source element 4314 are disposed above the point inspection jig 60 and are disposed toward the point inspection jig 60, and the fourth light source element 4316 is disposed below the point inspection jig 60 and is disposed toward the point inspection jig 60. It can be understood that the third detecting member 430 is used for detecting the assembling deviation of the lens 50 and the detecting ring 6110. Specifically, when the third light source is turned on and the fourth light source is turned off, the image information that the third camera 4312 can obtain is the size information of the three second fitting holes 510 and the size information of the detection hole 6112 in the middle. When the fourth light source is turned on and the third light source is turned off, the third camera 4312 may obtain the size information of the second matching hole 510 located at both sides and the detection hole 6112 located in the middle, and further may obtain the distance between the circle centers of the second matching hole 510 located in the middle and the detection hole 6112 located in the middle. It is understood that three corresponding detection rings 6110 are illustrated, and the size of the detection ring 6110 in the middle is smaller than the size of the second matching hole 510 in the middle of the installed lens 50, so that when the third light source element 4314 and the fourth light source element 4316 are turned on alternately and the third camera 4312 obtains the fourth image and the fifth image information, the offset distance between the centers of the detection rings 6110 in the middle and the second matching hole 510 can be obtained without turning over the detection cover 610. In other embodiments, two or three of the reduced detection rings 6110 may be provided, which is not limited herein.

It is understood that the third sensing member 430 may also be used to sense when the number of the first and second fitting holes 2110 and 510 is two. That is, the distance between the projections of the centers of the two first engaging holes 2110 and the second engaging holes 510 in the first direction and the second direction is the same as the above principle, and the using principle is not described herein again. When the number of the first matching holes 2110 and the second matching holes 510 is more than three, for example, four, please refer to fig. 15 and 16, 4 detection holes 6112 may be correspondingly disposed, so that the size of the detection holes 6112 is smaller than that of the second matching holes 510, and further the third camera 4312 may obtain the size information of the detection holes 6112 and the second matching holes 510, and further obtain the offset distance between the circle centers of the detection holes 6112 and the second matching holes 510 according to the obtained image. I.e., the offset distance a2 of the two centers in the first direction. It is understood that the projection of the center of each two second fitting holes 510 in the first direction or the second direction can be used to obtain the offset distance.

The lens lies in decorating before the circle assembly, need transport the lens to decorating the circle next door through the manipulator, but because in the lens transportation, the position of self second mating hole is uncertain, so before cooperating with decorating the circle, need the manipulator to change certain angle, make the second mating hole of lens and decorate the first mating hole position of circle corresponding. That is, the offset distance of the lens on the battery cover assembly relative to the electronic device cover needs to be detected. In an embodiment of the application, the first light source assembly may be turned on, the first camera obtains a third image, and then an offset distance of the lens on the battery cover assembly relative to the electronic device cover is obtained through the third image, please refer to fig. 21, for example, an included angle between a connection line between any two circle centers of the lens and the first direction is C, and before the assembly with the decoration ring, the manipulator corresponds to the rotation angle C, so that the connection line between the two circle centers of the lens is collinear with the first direction, and thus, the manipulator may correspond to the position of the second matching hole of the decoration ring. It will be appreciated that for products in which the bezel is angled with respect to the cover of the electronic device, the angle of deflection of the manipulator needs to be eliminated prior to engagement with the bezel when the lens is engaged with the product.

Referring to fig. 22 and 23, fig. 22 is a flowchart of a method for detecting an assembly deviation between the lens and the detection ring shown in fig. 17, and fig. 23 is a partial schematic view of the lens and the detection ring.

Wherein the content of the first and second substances,

s410: transporting the electronic equipment cover body with the decorative ring to a detection area;

s420: grabbing the lens and installing the lens at the decorative ring to form a battery cover assembly;

s430: and detecting the assembly error of the lens and the detection ring.

In an embodiment of the present application, a connection line between any two detection holes on the detection ring is aligned with the first direction, so that for an assembly deviation of the detection lens and the detection ring, the third light source element can be turned on, the fourth light source element can be turned off, and the third camera obtains a fourth image of the detection hole. And turning on the fourth light source element, turning off the third light source element, obtaining a fifth image of the detection hole and the lens by the third camera, and comparing the fourth image with the fifth image to obtain the assembly deviation of the lens and the detection ring. Referring to fig. 23, since the size of the middle detecting hole is smaller than the size of the second matching hole, the center of the circle connecting any two second matching holes is connected, and the included angle a4 between the detecting connecting line and the first direction corresponds to the offset distance between the lens and the detecting ring. In the embodiment of the present application, the center of the middle detecting hole and the center of the middle second matching hole are concentric, please refer to fig. 24, and fig. 24 is a partial structural schematic view of another embodiment between the lens and the detecting ring shown in fig. 22. It can be understood that the deflection angle of the lens can be obtained according to the included angle between the connection line of the circle centers of any two detection holes and the first direction, and then the assembly error between the second matching hole of the lens and the detection hole can be obtained according to the projection distance a6 in the first direction and the projection distance a7 in the second direction between the circle center of the middle detection hole and the circle center of the middle second matching hole respectively.
