[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] In the production and preparation process of electronic devices, multiple production processes are required, such as battery assembly, camera assembly, display assembly, etc. Usually, when assembling components such as batteries and cameras, board-to-board connectors (BTB) are used for connection. This connection method has the characteristics of compact structure, strong transmission capacity, and stable signal transmission.

[0023] During the installation of this type of connector, there may be problems such as inadequate connection and unstable connection. These problems are mainly caused by the operator's failure to follow the standard operating procedures during manual operation, and such subjective problems are inevitable. After these problems occur, there is a great risk of failure in the later stage, and there will be display abnormalities, the camera cannot be turned on, etc. There is currently no good way to solve this type of problem. The only way is to standardize the employees' operating methods to reduce market quality risks.

[0024] Based on this, the inventor of the present application proposed a method for detecting electronic devices in the assembly process by means of X-ray irradiation, and determining the installation status of the camera, battery, etc. under the display screen for detection. However, there are some components in the electronic device, such as circuits, which are sensitive to X-rays and may be damaged under X-ray irradiation. Therefore, the inventor of the present application proposed an electronic device detection shielding device and, based on the electronic device detection shielding device, proposed a detection method for electronic devices. In order to at least partially improve the above-mentioned technical problems. The embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

[0025] See also Figure 1 , Figure 1 An electronic device 10 is shown, comprising a middle frame 20 and a display screen 40 , wherein the display screen 40 is assembled on the middle frame 20 .

[0026] Please also read Figure 1 and Figure 2The middle frame 20 includes a middle plate 21 and a frame 22, wherein the middle plate 21 is a roughly plate-shaped structure and is used to install various types of components, the frame 22 is surrounded by the middle plate 21 and connected to the middle plate 21, and the display screen 30 is installed on the frame 22 during assembly and is roughly spaced relative to the middle plate 21. The frame 22 is formed with a step facing inward, and the display screen 30 is assembled on the step.

[0027] In this embodiment, please continue to refer to Figure 1 The electronic device 10 is a mobile phone. The electronic device 10 has a length direction Y and a width direction X, and the length direction Y and the width direction X are perpendicular to each other. The frame 22 includes a first frame 26 and a second frame 27 that are arranged opposite to each other, and a third frame 28 and a fourth frame 29 that are arranged opposite to each other. The third frame 28 and the fourth frame 29 are connected between the first frame 26 and the second frame 27. The first frame 26 and the second frame 27 are extended along the width direction X, and the third frame 28 and the fourth frame 29 are extended along the length direction Y. When the user normally holds and uses the electronic device 10, the first frame 26 is located at the top of the electronic device 10, and the second frame 27 is located at the bottom of the electronic device 10. The second frame 27 is provided with a charging port 25, and the charging port 25 can be used for charging by inserting a charging cable.

[0028] Please refer again Figure 1 The electronic device 10 may further include components such as a battery 30, a camera (not shown), and a mainboard 50, wherein the battery 30 is disposed inside the middle frame 20 and connected to the mainboard 50 via a board-to-board connector 60. Similarly, the camera may also be disposed inside the middle frame 20 and connected to the mainboard 50 via a board-to-board connector 60. The mainboard 50, the camera, the battery 30, the board-to-board connector 60 (hereinafter referred to as the connector 60) and other components are all located below the display screen 40. After the display screen 40 is installed and fastened during the assembly process, the operator cannot visually see the connection status of the connector 60 from one side of the display screen 40, and thus cannot visually evaluate the connection status or operating status of components such as the camera and the battery 30, and can only rely on power-on detection. However, the power-on detection cannot detect the electronic device 10 with an unstable connection of the connector 60, which may easily cause after-sales problems in the later stage.

[0029] See also Figure 3As a more specific embodiment, the display screen assembly 40 includes a light-transmitting cover plate 43, a capacitive touch layer 42, a light-emitting layer 41, a pixel circuit layer 44 and a backlight module 45. The capacitive touch layer 42 is arranged on the surface of the light-transmitting cover plate 43, the light-emitting layer 41 is arranged on the surface of the capacitive touch layer 42 away from the light-transmitting cover plate 43, the pixel circuit layer 44 is arranged on the surface of the light-emitting layer 41 away from the capacitive touch layer 42, and the backlight module 45 is arranged on the side of the pixel circuit layer 44 away from the light-emitting layer 41. The working principle of the display screen assembly 40 is: the backlight module 45 emits light, which enters the light-emitting layer 41 through the pixel circuit layer 44, and the pixel circuit layer 44 modulates the liquid crystal in the light-emitting layer 41 in a predetermined manner to form image light.

[0030] The light-transmitting cover plate 43 is a generally flat plate structure, for example, it can be made of tempered glass, which can protect the light-emitting layer 41 and allow light to pass through. The light-emitting layer 41 can be LED, OLED, etc., which is not limited in this embodiment.

[0031] X-rays, also known as X-rays, are electromagnetic waves with extremely high frequency, extremely short wavelength and high energy. The frequency range of X-rays is between 30PHz and 30EHz, the wavelength is 0.01 to 10 nanometers, and the energy is 124 electron volts to 124 kiloelectron volts. X-rays are penetrating, and when they pass through the object being measured, different images can be obtained after imaging processing.

[0032] By using X-rays to irradiate electronic devices, the status of various connectors 60 under the display screen 40 can be accurately imaged to determine the status of the connectors. However, various driving circuits are provided on the capacitive touch layer 42 and the pixel circuit layer 44. When these driving circuits are irradiated by X-rays, the threshold voltage (VTH), source power supply voltage (VSS), etc. will be abnormal, resulting in abnormal display. Among them, the threshold voltage refers to the critical value that triggers the flip in the circuit, which is one of the most important parameters of the liquid crystal material. The source power supply voltage refers to the common ground terminal voltage of the circuit.

[0033] It should also be noted that the electronic device 10 in the present application can be a mobile phone or a smart phone (for example, a phone based on iPhone TM, an Android TM-based phone), a portable gaming device (for example, Nintendo DS TM, PlayStationPortable TM, Gameboy Advance TM, iPhone TM), a laptop, a PDA, a portable Internet device, a music player, and a data storage device, other handheld devices, and devices such as watches, headphones, pendants, earphones, etc. The electronic device 10 can also be other wearable devices (for example, head-mounted devices (HMD) such as electronic glasses, electronic clothes, electronic bracelets, electronic necklaces, electronic tattoos, electronic devices 10, or smart watches).

[0034] The electronic device 10 can also be any one of a plurality of electronic devices 10, including but not limited to cellular phones, smart phones, other wireless communication devices, personal digital assistants, audio players, other media players, music recorders, video recorders, cameras, other media recorders, radios, medical devices, vehicle transportation instruments, calculators, programmable remote controls, pagers, laptop computers, desktop computers, printers, netbook computers, personal digital assistants (PDAs), portable multimedia players (PMPs), Moving Picture Experts Group (MPEG-1 or MPEG-2) Audio Layer 3 (MP3) players, portable medical devices, and digital cameras and combinations thereof.

[0035] See also Figure 4 This embodiment provides an electronic device detection shielding device 100, which includes a metal shielding portion 110 that cooperates with a display screen 40. The metal shielding portion 110 may be a roughly plate-shaped structure that can produce a shielding effect on X-rays. In some embodiments, the metal shielding portion 110 may be a lead plate or other metal plate. These metals have a good reflection effect on X-rays, preventing X-rays from passing through the metal shielding portion 110 and irradiating objects below the metal shielding portion 110, protecting the circuits on the pixel circuit layer 44 of the display screen 40 of the electronic device 10, and preventing these circuits from failing or being damaged after being irradiated by X-rays.

[0036] The configuration of the metal shielding portion 110 can be configured to be the same as the configuration of the electronic device 10. For example, if the electronic device 10 is a roughly rectangular structure, the metal shielding portion 110 can be configured to be the same rectangular structure as the electronic device 10. Preferably, the metal shielding portion 110 can completely cover the display screen 40 and the middle frame 20 of the electronic device to prevent X-rays from irradiating sensitive components within the electronic device when the electronic device is irradiated by X-rays.

[0037] For example, in a more specific embodiment, the metal shielding portion 110 includes a first edge 111 and a second edge 112 opposite to each other and a third edge 113 and a fourth edge 114 opposite to each other, wherein the third edge 113 and the fourth edge 114 are connected between the first edge 111 and the second edge 112, and when in use, the first edge 111 corresponds to the first frame 26 of the electronic device, the second edge 112 corresponds to the second frame 27 of the electronic device, the third edge 113 corresponds to the third frame 28 of the electronic device, and the fourth edge 114 corresponds to the fourth frame 29 of the electronic device. That is, the metal shielding portion 110 also has a length direction Y and a width direction X, wherein the first edge 111 and the second edge 112 are arranged along the width direction X, and the third edge 113 and the fourth edge 114 are arranged along the length direction Y. The first edge 111 can protrude outward from the first frame 26, the second edge 112 can protrude outward from the second frame 27, the third edge 113 can protrude outward from the third frame 28, and the fourth edge 114 can protrude outward from the fourth frame 29. That is, the dimensions of the metal shielding portion 110 in all directions are larger than the dimensions of the electronic device 10 in all directions so as to completely cover the electronic device 10.

[0038] The metal shielding portion 110 has one or more through holes 115, which pass through the metal shielding portion 110, and each through hole 115 corresponds to the position of the connector 60 under one or more display screens 40. That is, when the metal shielding portion 110 covers the top of the display screen 40, the position of the through hole 115 corresponds to the position of the connector 60 under one or more display screens 40. In this way, when X-ray irradiation is performed, the X-ray can pass through the through hole 115 and irradiate the display screen 40, and the image acquisition system 220 can capture the image of the connector 60 under the display screen 40, and then determine the connection status of the connector 60.

[0039] The cross section of each through hole 115 can be configured as a circle, a rectangle, a polygon, etc., which is not limited in this embodiment. The maximum aperture of the through hole 115 can be slightly larger than the maximum size of the corresponding connector 60, so that the X-ray camera passing through the through hole 115 can fully illuminate the connector 60 below. The opening position and number of the through hole 115 can be determined according to the position and number of the connector 60 below the electronic device 10. Figure 4 In the illustrated embodiment, the number of through holes 115 is 5, and the cross section of each through hole 115 is rectangular. It is understandable that in some other embodiments, the number of through holes 115 may also be other values.

[0040] The thickness of the metal shielding portion 110 can be set according to the amount of X-ray exposure. For example, in some embodiments, the thickness of the metal shielding portion 110 can be 1-5 mm. Of course, in some other embodiments, the thickness of the metal shielding portion 110 can also be other values, which is not limited in this embodiment.

[0041] When the electronic device detection shielding device 100 is used, the display screen 40 of the electronic device can be irradiated with X-rays. In order to avoid damaging other components of the electronic device, it is necessary to ensure that the electronic device detection shielding device 100 can be accurately aligned with the electronic device 10. In order to improve the positioning accuracy between the electronic device detection shielding device 100 and the electronic device 10. In one embodiment, refer to Figure 5 The electronic device detection shielding device 100 further includes a fixing portion 120, which is connected to the edge of the metal shielding portion 110 and protrudes toward one side of the metal shielding portion 110. Specifically, the fixing portion 120 can protrude along the side of the metal shielding portion 110 that faces the display screen 40. The advantage of this arrangement is that when in use, the electronic device detection shielding device 100 can be entirely covered on the electronic device 10, and the fixing portion 120 can play a role in positioning and fixing the electronic device 10, preventing the electronic device detection shielding device 100 from slipping relative to the electronic device 10 along the length direction Y or the width direction X of the electronic device 10, ensuring that the position of the through hole 115 always corresponds to the position of the connector 60 under the display screen 40 of the electronic device 10, and avoiding the through hole 115 being misaligned due to the slip of the electronic device detection shielding device 100 during the test, so that the X-rays irradiate other areas of the display screen 40 and damage other components of the electronic device 10.

[0042] The fixing portion 120 may be disposed only on one of the first edge 111, the second edge 112, the third edge 113, and the fourth edge 114 of the metal shielding portion 110, or may be disposed on more than one of the first edge 111, the second edge 112, the third edge 113, and the fourth edge 114 of the metal shielding portion 110, which is not limited in this embodiment. In particular, in a more specific embodiment, the fixing portion 120 is disposed on the first edge 111, the second edge 112, the third edge 113, and the fourth edge 114 at the same time, so that the fixing portion 120 can limit the metal shielding portion 110 in each direction, ensure the relative fixation between the metal shielding portion 110 and the electronic device, and ensure the position of the through hole 115 is fixed during the detection process.

[0043] During the testing process of the electronic device, other test items of the electronic device may be performed, such as the brightness test of the display screen 40. At this time, it is necessary to ensure that the battery of the electronic device has sufficient power. Therefore, during the testing process, it may be necessary to connect the power supply for charging. However, the fixing portion 120 disposed on the second edge 112 may block the charging port 25 of the electronic device 10. Therefore, see Figure 6 A socket 121 that cooperates with the charging port 25 of the electronic device 10 can be provided in the fixing portion 120 disposed on the second edge 112, so that the charging cable can be inserted from the socket 121 to charge the electronic device 10, thereby ensuring that the detection process of the electronic device 10 can proceed smoothly.

[0044] During the irradiation process, the X-ray passes through the through hole 115 and irradiates the electronic device for detection. The X-ray has a high degree of collimation, so the probability of deflection when passing through the through hole 115 is small. However, there is a possibility that the X-ray light source 230 is skewed or angularly deviated, resulting in the possibility that the X-ray is not incident perpendicular to the plane where the display screen 40 is located when passing through the through hole 115, which may cause the X-ray to irradiate other areas of the display screen 40 and damage components in other areas. In one embodiment, refer to Figure 7 The electronic device detection shielding device 100 further includes a fence portion 130, which is arranged around the edge of the metal shielding portion 110 adjacent to the through hole 115 and protrudes toward one side of the metal shielding portion 110. For example, the fence portion 130 may protrude toward the side of the metal shielding portion 110 away from the display screen 40, that is, the fence portion 130 and the fixing portion 120 are located on opposite sides of the metal shielding portion 110, and the fence portion 130 may be made of the same material as the metal shielding portion 110, for example, lead is used as the material of both the metal shielding portion 110 and the fence portion 130. The advantage of this arrangement is that when X-rays are not incident in a manner perpendicular to the plane where the display screen 40 is located, this part of the X-rays will be reflected on the fence portion 130 and will not be irradiated to the display screen 40, thereby avoiding damage to other components.

[0045] In another embodiment, see Figure 8 The fence portion 130 protrudes toward the side of the metal shielding portion 110 that faces the display screen 40, that is, the fence portion 130 and the fixing portion 120 are located on the same side of the metal shielding portion 110. In this arrangement, when in use, since the fence portion 130 is closer to the display screen 40, when X-rays are not incident in a manner perpendicular to the plane where the display screen 40 is located, a part of these X-rays will be directly reflected by the metal shielding portion 110 during propagation, and the other part will be reflected on the fence portion 130 even if it enters the through hole 115, which can better avoid damage to other components.

[0046] See also Fig. 9 This embodiment also provides an electronic device detection device 200, including the electronic device detection shielding device 100 ( Figure 4 ), an X-ray light source 230, an image acquisition system 220 and a control unit 210, the X-ray light source 230 and the image acquisition system 220 are electrically connected to the control unit 210, the control unit 210 can control the X-ray light source 230 to be turned on or off, the image acquisition system 220 is used to capture images of the electronic device under X-irradiation state, and the control unit 210 can determine the state of the connector 60 of the electronic device according to the image captured by the image acquisition system 220, and then determine whether the electronic device is qualified.

[0047] The control unit 210 may include a memory and a processor, and the processor may include one or more processing cores. The processor processes data by running or executing instructions, programs, code sets or instruction sets stored in the memory, and calling data stored in the memory. Optionally, the processor can be implemented in at least one hardware form of digital signal processing (DSP), field-programmable gate array (FPGA), and programmable logic array (PLA). The processor may integrate one or a combination of a central processing unit (CPU), a graphics processing unit (GPU), and a modem. Among them, the CPU mainly processes the operating system, user interface, and application programs; the GPU is responsible for rendering and drawing display content; and the modem is used to process wireless communications. It is understandable that the above-mentioned modem may not be integrated into the processor, but may be implemented separately through a communication chip.

[0048] The memory may include a random access memory (RAM) or a read-only memory (ROM). The memory may be used to store instructions, programs, codes, code sets or instruction sets. The memory may include a program storage area and a data storage area, wherein the program storage area may store instructions for implementing an operating system, instructions for implementing at least one function (such as an image acquisition function, etc.), instructions for implementing the following various method embodiments, etc. The data storage area may also store data created by the detection device during use, etc.

[0049] The electronic device detection device 200 can automatically collect and detect the status of the connector 60 of the electronic device to determine whether the electronic device is qualified, thereby preventing subsequent after-sales problems.

[0050] See also Fig.10 This embodiment further provides a method for detecting an electronic device, which is applied to the electronic device detection device 200 described above, and the method includes:

[0051] Step S110: using an electronic device detection shielding device to cover the display screen so that the connector below the display screen is exposed from the through hole.

[0052] Step S120: Turn on the X-ray light source, use X-rays to irradiate the display screen, and control the image acquisition system to acquire an image of the electronic device.

[0053] When the display screen is irradiated with X-rays, the X-rays can be controlled to be perpendicular or nearly perpendicular to the plane where the display screen is located.

[0054] Step S130: Determine the state of the connector according to the image.

[0055] By using the electronic equipment detection shielding device to detect electronic equipment during the assembly process, it is possible to avoid damage to the display screen or circuit during the detection process, and at the same time accurately detect electronic equipment with defects during the assembly process.
