Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be noted that the following examples are only illustrative of the present application, and do not limit the scope of the present application. Likewise, the following examples are only some examples and not all examples of the present application, and all other examples obtained by a person of ordinary skill in the art without any inventive work are within the scope of the present application.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

As used herein, an "electronic device" (or simply "terminal") includes, but is not limited to, an apparatus that is configured to receive/transmit communication signals via a wireline connection, such as via a Public Switched Telephone Network (PSTN), a Digital Subscriber Line (DSL), a digital cable, a direct cable connection, and/or another data connection/network, and/or via a wireless interface (e.g., for a cellular network, a Wireless Local Area Network (WLAN), a digital television network such as a DVB-H network, a satellite network, an AM-FM broadcast transmitter, and/or another communication terminal). A communication terminal arranged to communicate over a wireless interface may be referred to as a "wireless communication terminal", "wireless terminal" or "mobile terminal". Examples of mobile terminals include, but are not limited to, satellite or cellular telephones; a Personal Communications System (PCS) terminal that may combine a cellular radiotelephone with data processing, facsimile and data communications capabilities; PDAs that may include radiotelephones, pagers, internet/intranet access, Web browsers, notepads, calendars, and/or Global Positioning System (GPS) receivers; and conventional laptop and/or palmtop receivers or other electronic devices that include a radiotelephone transceiver. A cellular phone is an electronic device equipped with a cellular communication module.

It should be noted that the electronic device in the embodiment of the present application is mainly directed to an electronic device having a display screen with an opening and a camera structure under the display screen, such as a mobile phone with a hole-digging screen. In order to improve the screen ratio, the front camera of the mobile phone is arranged below the screen, and holes are formed in the position, corresponding to the front camera, of the display screen, so that the camera can be normally used.

In the related art, before assembling the front camera of the mobile phone, the front bracket is generally fixed at a corresponding position of a frame (e.g., a middle frame) of the mobile phone, and then the front camera is assembled on the front bracket. However, the applicant found in the research that the assembly mode is realized based on the alignment of the front support and the mobile phone frame, and is not directly aligned with the mobile phone opening position through the camera. After the assembly is completed, due to the existence of accumulated tolerance, the alignment of the camera and the opening position of the display screen can be deviated. In addition, after the front support is fixed with the mobile phone frame, when the front camera is assembled, assembly deviation may exist between the front support and the front camera, and deviation may further occur in alignment of the camera and the display screen opening position.

Based on this, the applicant found in the research that a direct alignment method is proposed to assemble the components so as to avoid the alignment deviation caused by the accumulated tolerance or the assembly tolerance.

Specifically, referring to fig. 1, fig. 1 is a schematic structural diagram of an electronic device in some embodiments of the present application, where the electronic device may be an electronic device having a hole-digging screen and a camera under the screen, such as a tablet computer, a mobile phone, a camera, a personal computer, a notebook computer, a vehicle-mounted device, and a wearable device. The electronic device 100 may generally include a middle frame assembly 10, a front assembly 20, and a rear cover 30, wherein the front assembly 20 is disposed between the middle frame assembly 10 and the rear cover 30. The middle frame assembly 10 and the rear cover 30 enclose an accommodating space 101, and the front assembly 20 is disposed in the accommodating space 101.

Specifically, referring to fig. 2, fig. 2 is a schematic diagram illustrating a structure of an electronic device in the embodiment of fig. 1 of the present application in a disassembled state, the middle frame assembly 10 may include a middle frame 11, a display module 12 and a cover plate 13, the display module 12 is located between the middle frame 11 and the cover plate 13, and the front assembly 20 may be located between the middle frame 11 and the rear cover 30. In the structural application of the electronic device 100, the middle frame 11 is generally used to carry or fix internal components of the electronic device 100, the cover plate 13 may be a glass cover plate, and the Display module 12 may be one of an OLED (Organic Light-Emitting Diode) Display screen, an LCD (Liquid Crystal Display), an LED (Light-Emitting Diode) Display screen, and the like. It will be appreciated that the front module 20 is fixedly attached to the center frame module 10 by a fixed mounting.

In view of the above, an embodiment of the present application provides a method for installing a front module 20, and specifically, please refer to fig. 3, where fig. 3 is a schematic flow chart of an installation method of the front module 20 in some embodiments of the present application, the installation method generally includes the following steps:

s301, providing a middle frame assembly 10, wherein the middle frame assembly 10 is provided with a mounting hole and a dispensing area.

Specifically, please refer to fig. 4, fig. 4 is a schematic structural diagram of the middle frame 11 according to some embodiments of the present application, in which the middle frame 11 is provided with a mounting hole 111 and a dispensing area 112. The mounting holes 111 penetrate through the dispensing region 112, and the dispensing region 112 is disposed on a side of the middle frame 11 away from the display module 12, i.e., the dispensing region 112 is disposed on a side of the middle frame 11 close to the front device 20, so as to fixedly connect the middle frame device 10 and the front device 20. In other words, the display module 12 is disposed on a side of the middle frame 11 away from the dispensing region 112, and the display module 12 is provided with a light hole 120 corresponding to the mounting hole 111, so that light can sequentially pass through the light hole 120 and the mounting hole 111 and irradiate the front module 20, and the camera of the front module 20 can be normally used.

It can be understood that the aperture of the mounting hole 111 is generally slightly larger than the aperture of the light hole 120, so that when the middle frame 11 and the display module 12 are assembled, the situation that the mounting hole 111 shields the light hole 120 due to assembly tolerance and process error is avoided, and then the image collected by the camera is lost. Of course, the aperture difference range between the aperture of the mounting hole 111 and the aperture of the light hole 120 can be flexibly set according to the camera image capturing viewing angle and the layout of the display module, which is not specifically limited in this application.

And S302, dispensing in the dispensing area 112. Specifically, the glue can be dispensed in the dispensing area 112 by dispensing glue, so that the glue is disposed around the outer periphery of the mounting hole 111.

For example, the Adhesive disposed in the dispensing region 112 may be a highly Adhesive such as UV (Ultraviolet ray curable) Adhesive, OCA (optical Clear Adhesive), double-sided Adhesive, or the like.

S303, moving the front module 20 to make the front bracket of the front module 20 abut against the dispensing area 112 and make the front camera of the front module 20 face the mounting hole 111.

Specifically, referring to fig. 5, fig. 5 is a schematic structural diagram of a front module 20 according to some embodiments of the present disclosure, where the front module 20 may generally include a front bracket 21 and a front camera 22. The front bracket 21 is used for connecting and fixing with an external structure when the front assembly 20 is installed, so as to position the front camera 22. The front camera 22 is disposed in the accommodating space 101, and in order to collect light for normal use, the front camera 22 generally faces the mounting hole 111 of the middle frame 11 to receive external light.

Furthermore, because the front-mounted bracket is mounted on the middle frame, and then the front-mounted camera is mounted on the front-mounted bracket, the accumulated tolerance and the alignment deviation are generated, and the product quality is influenced. In the embodiment of the present application, the front module 20 includes the front bracket 21 and the front camera 22 integrally, that is, during the process of installing the front module 20, the front camera 22 can be directly used for alignment, so as to avoid alignment deviation caused by accumulated tolerance or assembly tolerance.

S304, curing the glue in the glue dispensing region 112 to fix the front assembly 20 and the middle frame assembly 11. Specifically, in the process of moving the front module 20, when the front bracket 21 of the front module 20 abuts against the dispensing area 112 and the front camera 22 faces the mounting hole 111, it indicates that the front camera 22 has completed alignment, and at this time, the glue is cured, so that the front module 20 is fixedly connected with the middle frame module 11, alignment deviation caused by accumulated tolerance or assembly tolerance can be avoided, and the assembly accuracy of the front camera 22 is ensured.

It can be understood that when the glue body for dispensing is UV glue, the glue body can be cured by UV curing; when the dispensed glue is OCA optical glue, the glue can be cured at room temperature or medium temperature, and when the dispensed glue is double-sided glue, the curing is completed when the front support 21 abuts against the dispensing region 112.

Further, the installation method provided by the embodiment of the application can be completed through automatic equipment, for example, the middle frame assembly is placed on the horizontal production line and gradually moved to the dispensing position, dispensing is performed on the dispensing area corresponding to the middle frame assembly through the dispensing equipment, then the front-mounted assembly is moved through the suction or gripping device, when the front-mounted camera of the front-mounted assembly is right opposite to the installation hole of the middle frame assembly, the front-mounted assembly is further moved so that the front-mounted support is abutted against the dispensing area of the middle frame, and finally, glue in the dispensing area is cured, so that the front-mounted assembly is fixedly connected with the middle frame assembly.

Of course, in other embodiments, in the process of moving the front module, the front bracket may be abutted to the dispensing area of the middle frame, and then the front module is moved so that the front camera directly faces the mounting hole of the middle frame module.

It can be understood that in the process of curing the colloid, when the front support of the front component abuts against the dispensing area, the colloid can be preliminarily fixed. And after the alignment of the front camera is completed, secondary curing is performed on the colloid so as to ensure the connection stability of the front assembly and the middle frame assembly.

According to the mounting method of the front assembly, the front assembly is assembled by directly aligning the mounting holes of the front camera and the middle frame assembly, the influence of accumulated tolerance and assembly error on the assembly precision of the front camera is avoided, the assembly precision of the front assembly is improved, and the product quality and the generation efficiency are improved.

Referring to fig. 6, fig. 6 is a schematic view of a partial laminated structure of the electronic device 100 at a mounting hole position according to some embodiments of the present disclosure, in which the display module 12 generally includes a display layer 121 and an ink layer 122 that are laminated, the display layer 121 is disposed close to the middle frame 11, and the ink layer 122 is disposed far from the middle frame. In other words, the display layer 121 is disposed away from the cover plate 13, and the ink layer 122 is disposed close to the cover plate 13.

Further, the display layer 121 and the ink layer 122 are respectively opened with a first through hole 1211 and a second through hole 1222 facing the mounting hole 111. In other words, the display layer 121 has a first through hole 1211, and the ink layer 122 has a second through hole 1222. The first through hole 1211 and the second through hole 1222 are respectively disposed opposite to the mounting hole 111.

It can be understood that, to ensure the normal use of the front camera, the light of the light-transmitting middle frame assembly 10 should completely irradiate the front camera, and in order to avoid the error of the middle frame assembly 10 itself during the assembly, the corresponding hole is usually set. For example, the diameter of the mounting hole 111 is generally the largest, the diameter of the first through hole 1211 is the next largest, and the diameter of the second through hole 1222 is the smallest. The aperture of the lens 221 of the front camera 22 is generally smaller than that of the second through hole 1222, so as to achieve a better lens angle.

In some embodiments of the present application, the suction or gripping device of the front module 20 generally adjusts the state of the front module 20 before moving the front module 20 so that the front module 20 is in an optimal position before assembly.

It should be noted that the terms "first", "second" and "third" in the present application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of indicated technical features. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature.

Based on this, the installation method provided in some embodiments of the present application may further include, before step S303 (i.e., before moving the front assembly 20): the front module 20 is grasped and the angle of the front module 20 is adjusted so that the plane of the lens 221 of the front camera is parallel to the display module 12. Specifically, referring to fig. 7, fig. 7 is a flow chart illustrating a method for mounting the front module 20 according to some embodiments of the present application, the method generally includes the following steps:

s701, providing a middle frame assembly; this step may refer to step S301 of the previous embodiment.

S702, dispensing in a dispensing area of the middle frame assembly; this step may refer to step S302 of the foregoing embodiment.

S703, grabbing the front-mounted component and adjusting the angle of the front-mounted component so that the plane where the lens of the front-mounted camera is located is parallel to the display module.

Particularly, snatch leading subassembly through snatching equipment to the angle of adjusting leading subassembly, so that the camera lens of leading camera is parallel with display module assembly, in order to avoid at the in-process of installation leading subassembly, leading subassembly causes the impaired condition of display module assembly to take place owing to the slope.

S704, moving the front-mounted component; this step may refer to step S303 of the foregoing embodiment.

S705, solidifying the colloid in the dispensing area to fix the front-mounted component and the middle frame component; this step may refer to step S304 of the foregoing embodiment. It can be understood that, in the process of curing the glue in the glue dispensing area, it is generally necessary to maintain the state of the device for sucking or grabbing the front module, so as to avoid the assembly accuracy being affected by the misalignment between the front module and the middle frame module when the curing is not completed.

In other embodiments of the present application, a method of directly aligning a camera with a display module is used to achieve accurate positioning of the camera, specifically, please refer to fig. 8, where fig. 8 is a schematic flow chart of an installation method of a front module in other embodiments of the present application, where the installation method substantially includes the following steps:

s801, providing a middle frame assembly; this step may refer to step S301 of the previous embodiment.

S802, dispensing in a dispensing area of the middle frame assembly; this step may refer to step S302 of the foregoing embodiment.

And S803, acquiring the position coordinate of the first through hole, capturing the position coordinate of the lens of the front camera, confirming the offset of the position coordinate of the lens relative to the position coordinate of the first through hole, and moving the front assembly according to the offset.

Particularly, through the position coordinate who snatchs the camera lens and the position coordinate of first through-hole to can remove leading subassembly according to the position coordinate of camera lens and the offset of the position coordinate of first through-hole, and then realize the accurate location of camera lens through the mode that camera lens and first through-hole directly counterpoint, avoid accumulative total tolerance or assembly tolerance and the counterpoint deviation that causes, promote the precision of leading camera assembly, and then promote product quality and production efficiency.

S804, moving the front-mounted component; this step may refer to step S303 of the foregoing embodiment.

S805, solidifying the colloid in the dispensing area to fix the front-end assembly and the middle frame assembly; this step may refer to step S304 of the foregoing embodiment.

In the embodiment of the application, the step S803 is added before the front device is moved, so that the lens is accurately positioned, and alignment deviation caused by accumulated tolerance or assembly tolerance is avoided, thereby improving the product quality and the production efficiency.

It is understood that in actual production, after the front assembly is assembled, the position of the camera is usually measured to confirm whether the lens is concentric with respect to the first through hole of the display layer, or further confirm whether the eccentric distance of the lens with respect to the first through hole meets the preset eccentric value.

Specifically, in the center frame assembly equipped with the front assembly, the position coordinates of the relevant part are acquired by an image-capturing device such as a CCD camera, and it is determined whether or not the eccentric distance of the lens with respect to the first through hole meets a preset eccentric value by a corresponding calculation. Based on this, the purpose of detection is achieved by grasping the position coordinates of the relevant parts in steps.

First, when the middle frame component is not assembled with the front component, it may be understood that the position coordinates of the first through hole and the second through hole are acquired by the image capture apparatus either in step S803 or before step S804 (S303).

Specifically, referring to fig. 9, fig. 9 is a schematic diagram of a position coordinate capturing method in some embodiments of the present application, where the position coordinate capturing method is implemented on a side of the middle frame 11 away from the display module 12. That is, the first position coordinates of the first through hole 1211 and the second position coordinates of the second through hole 1222 are obtained at the side of the middle frame 11 away from the display module 12. The first position coordinate is at least the center coordinates (X1, Y1) of the first through hole 1211, and the second position coordinate is at least the center coordinates (X2, Y2) of the second through hole 1222.

For example, a picture is taken in the m direction shown in fig. 9 by a CCD camera, the first through hole 1211 and the second through hole 1222 are grasped, and the coordinates of the center of the first through hole 1211 (X1, Y1) and the coordinates of the center of the second through hole 1222 (X2, Y2) are stored in a device having a storage function. It should be noted that all the directional indicators (such as upper, lower, left, right, front and rear … …) in the embodiment of the present application are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicator is changed accordingly.

Further, a first eccentric coordinate of the first through hole 1211 with respect to the second through hole 1222 is obtained according to the first position coordinate and the second position coordinate. It can be understood that, in the manufacturing process of the display module 12, there is a certain eccentricity tolerance between the first through hole 1211 of the display layer 121 and the second through hole 1222 of the ink layer 122, that is, there is a non-concentricity, i.e., an eccentricity, between the first through hole 1211 and the center of the second through hole 1222. The embodiment of the present application first obtains the eccentric distance of the first through hole 1211 relative to the second through hole 1222 before confirming whether the eccentric distance of the lens relative to the first through hole satisfies the preset eccentric value, and further obtains the eccentric distance of the lens relative to the first through hole after calculating according to the eccentric distance of the lens relative to the second through hole 1222.

Since it is difficult to simultaneously obtain the position coordinates of the first through hole 1211 and the second through hole 1222 in the m direction shown in fig. 9 after the front assembly is assembled, the embodiment of the present application obtains the position coordinates of the first through hole 1211 and the second through hole 1222 before the front assembly is assembled, and thus obtains the eccentric distance of the first through hole 1211 with respect to the second through hole 1222.

In conjunction with the above, the first position coordinates of the first through hole 1211 and the second position coordinates of the second through hole 1222 are obtained by using an image capturing device such as a CCD camera, and the first eccentric coordinates of the first through hole 1211 with respect to the second through hole 1222 are obtained from the first position coordinates and the second position coordinates. In the embodiment of the present application, a circle center coordinate is taken as an example to describe an obtaining manner of the first eccentric coordinate.

Specifically, the specific way of obtaining the first eccentric coordinates (P1, Q1) according to the center coordinates (X1, Y1) of the first through hole 1211 and the center coordinates (X2, Y2) of the second through hole 1222 is as follows: p1 ═ X1-X2, Q1 ═ Y1-Y2. Namely, the first eccentric coordinates are (X1-X2, Y1-Y2).

After the front assembly is assembled, as shown in fig. 6, since the side of the lens 221 of the front camera 22 facing away from the cover plate 13 is generally opaque, the third position coordinate of the lens 221 and the fourth position coordinate of the second through hole 1222 of the ink layer 122 can only be obtained at the side of the middle frame 11 close to the display module 12. Similarly, the third position coordinate and the fourth position coordinate are illustrated by taking the center coordinate as an example. Based on this, in the embodiment of the present application, the third position coordinate is at least the center coordinates (X3, Y3) of the lens 221, and the fourth position coordinate is at least the center coordinates (X4, Y4) of the second through hole 1222.

For example, a photograph is taken in the n direction shown in fig. 6 by a CCD camera, the lens 221 and the second through hole 1222 are grasped, and the center coordinates (X3, Y3) of the lens 221 and the center coordinates (X4, Y4) of the second through hole 1222 are stored in a device having a memory function.

Further, a second eccentric coordinate of the lens 221 with respect to the second through hole 1222 is acquired according to the third position coordinate and the fourth position coordinate. It is understood that after the front assembly 20 is mounted, there may be an eccentric tolerance between the lens 221 and the first through hole 1211 of the display layer 121, and the lens 221 and the first through hole 1211 cannot be directly and simultaneously captured. Therefore, in the embodiment of the present application, the eccentric distance of the lens 221 with respect to the first through hole 1211 is obtained in a manner of grabbing the position coordinates of the second through hole 1222 of the ink layer 122.

Specifically, in the embodiment of the present application, before confirming whether the eccentric distance of the lens 221 with respect to the first through hole 1211 meets the preset eccentric value, the eccentric distance of the lens 221 with respect to the second through hole 1222 is further obtained, and the eccentric distance of the lens 221 with respect to the first through hole 1211 is calculated according to the eccentric distance of the first through hole 1211 with respect to the second through hole 1222.

Based on this, in the embodiment of the present application, after the front assembly 20 is assembled, the position coordinates of the lens 221 and the second through hole 1222 are obtained, and thus the eccentric distance of the lens 221 with respect to the second through hole 1222 is obtained. In conjunction with the above-mentioned image capture device such as a CCD camera, the third positional coordinate of the lens 221 and the fourth positional coordinate of the second through hole 1222 are obtained at the side of the middle frame 11 close to the display module 12 (i.e., in the n direction shown in fig. 6), and the second eccentric coordinate of the lens 221 with respect to the second through hole 1222 is obtained according to the third positional coordinate and the fourth positional coordinate. In the embodiment of the present application, a circle center coordinate is taken as an example to describe an obtaining manner of the second eccentric coordinate.

Specifically, the specific way of obtaining the second eccentric coordinates (P2, Q2) according to the center coordinates (X3, Y3) of the lens 221 and the center coordinates (X4, Y4) of the second through hole 1222 is as follows: p2 ═ X3-X4, Q2 ═ Y3-Y4. I.e., the second eccentric coordinates are (X3-X4, Y3-Y4).

Further, the eccentric coordinates (P0, Q0) of the lens 221 with respect to the first through hole 1211 may be acquired according to the first eccentric coordinates (P1, Q1) and the second eccentric coordinates (P2, Q2). The specific way of acquiring the eccentric coordinates (P0, Q0) according to the first eccentric coordinates (P1, Q1) and the second eccentric coordinates (P2, Q2) is as follows: P0-P2-P1, Q0-Q2-Q1. That is, the eccentric coordinates of the lens 221 with respect to the first through hole 1211 are (P2-P1, Q2-Q1), and the eccentric coordinates of the lens 221 with respect to the first through hole 1211 are further calculated as ((X3-X4) - (X1-X2), (Y3-Y4) - (Y1-Y2)).

In some embodiments of the present application, the eccentric distance L of the lens 221 with respect to the first through hole 1211 can be acquired by acquiring the eccentric coordinates (P0, Q0) of the lens 221 with respect to the first through hole 1211, that is, the eccentric distance L of the lens 221 with respect to the first through hole 1211 is acquired from the eccentric coordinates (P0, Q0). The specific way of acquiring the eccentric distance L of the lens 221 relative to the first through hole 1211 according to the eccentric coordinates (P0, Q0) is as follows:

further, the eccentric distance L of the lens 221 relative to the first through hole 1211 is obtained, and whether the eccentric distance L of the lens 221 relative to the first through hole 1211 meets the preset eccentric value L0 is determined. It can be understood that, in the assembly process of the electronic device, whether the electronic device is a high-quality product is usually determined by presetting some standard values, and then comparing the detected value with the standard values in the process of detecting the product, so as to draw a conclusion whether the product meets the production quality. Based on this, the embodiment of the present application compares the obtained eccentric distance L of the lens 221 relative to the first through hole 1211 with the preset eccentric value L0, and when the eccentric distance L of the lens 221 relative to the first through hole 1211 does not exceed the preset eccentric value L0 (i.e., L ≦ L0), it is determined that the assembling accuracy of the lens 211 meets the product quality requirement. In the embodiment of the present application, the preset eccentricity L0 is generally 0.05-0.20mm, for example, the preset eccentricity L0 may be 0.05mm, 0.10mm, 0.15mm, 0.20mm, or the like.

In some embodiments of the present application, before moving the front module, the movement stroke of the front module generally needs to be obtained in advance, that is, after the lens is aligned with the display module, the moving distance of the lens needs to be obtained, so that the lens can be accurately positioned and the front bracket can be stably connected with the middle frame.

Referring to fig. 10, fig. 10 is a schematic flow chart illustrating a method for mounting a front module according to another embodiment of the present application, the method generally includes the following steps:

s1001, providing a middle frame assembly; this step may refer to step S301 of the previous embodiment.

S1002, dispensing in a dispensing area of the middle frame assembly; this step may refer to step S302 of the foregoing embodiment.

S1003, acquiring the position coordinate of the cover plate, confirming the height difference of the position coordinate of the lens relative to the position coordinate of the cover plate, and moving the front assembly according to the height difference.

Specifically, the position coordinates of the cover plate with respect to the system origin are acquired by a height measuring device such as a laser device, and the position coordinates of the lens are acquired with reference to the manner of acquiring the position coordinates of the lens described in the foregoing embodiments. And then the height difference of the position coordinate of the lens relative to the position coordinate of the cover plate can be confirmed and acquired according to the height coordinate of the cover plate and the position coordinate of the lens, so that the movement stroke of the front assembly can be determined. In other words, after the height difference between the lens and the cover plate is obtained, when the front module is moved, the front module can be moved by referring to the height difference, and the phenomenon that the moving stroke of the moving module is too long or too short to influence the assembly precision and the assembly stability is avoided.

It is understood that the height of the surface of the cover plate and the surface of the lens can be measured in the n direction shown in fig. 6 by using a laser height measuring device, so as to obtain a distance value between the lens and the cover plate. Generally speaking, the distance between camera lens and the apron is advanced excessively or the shooting effect of camera can all be influenced too far away, consequently in actual production, can set up the preset distance that accords with product quality requirement between camera lens and the apron generally to carry out the comparison with the detected value in the testing process, more quick acquisition product quality information. Furthermore, the preset distance between the lens and the cover plate is generally 0.10-0.30mm, and within the distance range, the shooting effect of the camera cannot be greatly influenced.

Specifically, in actual production, the preset distance between the lens and the cover plate can be set to be 0.10-0.20mm, so that the fluctuation range of the distance between the lens and the cover plate is small, and the consistency of product quality is favorably realized.

The embodiment of the application compares the distance between the lens and the cover plate with the preset distance to obtain a product meeting the quality requirement. Meanwhile, the consistency of the product quality can be improved by setting the range of the preset distance.
