Description

Technical Field

[0001] This invention belongs to the field of terminal testing technology, specifically relating to a fixture, terminal testing equipment, and terminal testing method. Background Technology

[0002] With the development of society, users are coming into contact with more and more terminals, such as POS machines, PDAs, and mobile phones that people use in their daily lives. Moreover, in order to meet the needs of people's daily life and work, current terminals are usually equipped with cameras. The functions of the cameras include shooting and scanning functions, such as taking photos, recording videos, and recognizing QR codes, identification codes, and barcodes.

[0003] To facilitate the function of the camera, current terminals typically have a front camera on the front, i.e., the screen, and a rear camera on the back, i.e., the side opposite the screen. At the same time, such terminals need to undergo quality inspection before leaving the factory, and a crucial part of the inspection is the performance testing of the camera in the terminal.

[0004] Currently, with the rapid development of automation technology, automated testing equipment is also being applied to the quality inspection of terminals. For example, terminals are held in fixtures, and bionic mechanisms are used to test the touch performance of the screen. When using automated testing equipment to test terminals, it is necessary to hold the terminal to be tested. In order to test the touch performance of the screen of the terminal to be tested, it is necessary to hold the terminal to be tested from the back and sides. This means that the fixture holding the terminal to be tested is directly opposite the rear camera of the terminal. Therefore, how to test the rear camera of the terminal has become a problem.

[0005] Furthermore, given the multiple functions of cameras, finding a single automated detection device that can detect both the shooting and scanning functions of the rear camera is also a challenge. Summary of the Invention

[0006] The primary objective of this invention is to provide a fixture to address the aforementioned problems encountered when using automated inspection equipment to inspect the rear camera of a terminal under test. A second objective of this invention is to provide a terminal inspection device. A third objective of this invention is to provide a terminal inspection method.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] As a first aspect of the invention, a jig is proposed, comprising:

[0009] The fixture includes a clamping part for placing a terminal to be tested. The clamping part has a cavity and a first opening corresponding to the rear camera of the terminal to be tested placed on the clamping part. The area inside the cavity that the rear camera faces through the first opening is the shooting area.

[0010] A linear motion unit, which is connected to the clamp;

[0011] A signboard, which is connected to the linear motion unit, is driven by the linear motion unit to enter or exit the shooting area;

[0012] By setting a chamber on the clamp, and setting a first opening on the chamber corresponding to the position of the rear camera of the terminal to be tested, and setting a light-transmitting sheet in the first opening that is adapted to the size of the first opening, when the terminal to be tested is placed on the clamping part, the rear camera can take pictures of the interior of the chamber through the first opening, thereby providing space to set a first mark for testing the rear camera's shooting function or scanning function. The first mark can be an image and / or color swatch for testing the shooting function, or a barcode and / or QR code for testing the scanning function, etc., with specific information.

[0013] Furthermore, by using a linear motion unit to drive the label plate into the shooting area, a carrier for setting a second label that is different from the first label is provided, thus enabling the detection of the scanning or shooting function of the rear camera without moving the terminal to be tested.

[0014] In other words, the same testing equipment can detect both the shooting function of the rear camera of the terminal under test and the scanning function of the rear camera of the terminal under test.

[0015] Preferably, the fixture proposed in this invention further includes a supplementary light, which is disposed in the cavity.

[0016] Preferably, the clamping part includes a main body and an open box, the first opening is provided on the main body, the open box is provided below the main body and connected to the main body, and the interior of the open box is located within the shooting area.

[0017] Preferably, a second opening is provided at the connection between the open box and the main body, and the marking plate is driven by the linear motion unit to enter / exit the shooting area from the second opening;

[0018] By providing a second opening, the linear motion unit and / or the label plate can be installed more conveniently.

[0019] Preferably, the clamping part further includes a pressure ring, which is connected to the main body and is located above the main body.

[0020] Furthermore, the clamping part in the fixture proposed in this invention also includes a flexible member, which is disposed on the pressure ring and located between the pressure ring and the terminal to be tested.

[0021] Furthermore, the pressure ring is hinged to the main body, and the pressure ring is rotatable relative to the main body with the hinge point as the fulcrum.

[0022] As a second aspect of the invention, a terminal detection device is provided, comprising the fixture as described above, and a control unit electrically connected to the linear motion unit and the terminal to be detected placed on the clamping part.

[0023] As a third aspect of the present invention, a terminal detection method for a terminal detection device as described above is proposed, wherein a first mark is provided on the inner bottom surface of the chamber opposite to the first opening, and a second mark is provided on the mark plate. The mark plate is located outside the shooting area in a first state, and the second mark on the mark plate is located within the shooting area in a second state. The specific detection steps are as follows:

[0024] Step 1: Enter the first original information of the first identifier and the second original information of the second identifier into the control unit;

[0025] Step 2: In the first state, the control unit generates a first instruction and sends the first instruction to the terminal to be tested placed on the clamping part;

[0026] The terminal to be tested receives and executes a first instruction to control the rear camera to take a picture of the first identifier, generate first image information, and feed the first image information back to the control unit;

[0027] After receiving the first image information, the control unit compares the received first image information with the first original information. If they match, the detection result is qualified; otherwise, the detection result is unqualified.

[0028] Step 3: The control unit generates a second instruction and sends the second instruction to the linear motion unit. The linear motion unit receives and executes the second instruction, causing the second identifier to move from the first state to the second state.

[0029] Step 4: In the second state, the control unit generates a third instruction and sends the third instruction to the terminal to be tested placed on the clamping part;

[0030] The terminal to be tested receives and executes the third instruction, controls the rear camera to take a picture of the second identifier, generates second image information, and feeds back the second image information to the control unit;

[0031] After receiving the second image information, the control unit compares the received second image information with the second original information. If they match, the detection result is qualified; otherwise, the detection result is unqualified.

[0032] The present invention provides a fixture, a terminal testing device, and a terminal testing method, the advantages of which are: it enables the testing of different functions of the rear camera of the terminal to be tested, which is beneficial to improving integration and accuracy; specifically, it is reflected in:

[0033] First, by setting a chamber on the fixture and setting a first opening on the chamber corresponding to the position of the rear camera of the terminal to be tested, when the terminal to be tested is placed on the clamping part, the rear camera can capture images of the interior of the chamber through the first opening, thus providing space to set a first mark for detecting the rear camera's shooting or scanning functions. At the same time, a linear motion unit drives the mark plate into the shooting area, thus providing a carrier for setting a second mark that is different from the first mark, realizing the detection of the rear camera's scanning or shooting functions. By using the first mark set on the inner bottom surface of the chamber opposite to the first opening and the second mark set on the mark plate driven into or out of the shooting area by the linear motion unit, both the shooting function and the scanning function of the rear camera of the terminal to be tested can be detected on the same testing device. Furthermore, since the setting positions of the chamber and the first opening do not interfere with the bionic mechanism used to detect screen touch, audio, surface defects, or the button detection module used to detect side buttons, they can be integrated into the same terminal testing device, which is beneficial to improving the integration of the terminal testing device.

[0034] Secondly, and further still, by setting up supplementary lighting, different lighting environments can be provided to the cavity when detecting the rear camera, thereby enabling the detection of the rear camera's shooting and scanning functions under different lighting intensities.

[0035] Third, by setting a light-transmitting sheet inside the first opening, the chamber becomes a sealed space, which prevents dust from entering the chamber and contaminating the first or second mark, thereby improving the accuracy of the detection. Attached Figure Description

[0044] The present invention will be further described in detail below with reference to the accompanying drawings.

[0045] As the first aspect of this embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a fixture includes a clamp 1, a linear motion unit 3, and an identification plate 4. The clamp 1 has a clamping part 11 for placing a terminal 8 to be tested and a chamber 2 provided on the clamping part 11. The chamber 2 has a first opening 21 corresponding to the rear camera of the terminal 8 to be tested placed on the clamping part 11. The area inside the chamber 2 directly opposite to the rear camera through the first opening 21 is the shooting area. The linear motion unit 3 is connected to the clamp 1. The identification plate 4 is connected to the linear motion unit 3. The identification plate 4 is driven by the linear motion unit 3 to enter or exit the shooting area through the opening.

[0046] It should be noted that the linear motion unit 3 proposed in this embodiment refers to a structure that can convert electrical energy into linear motion, such as an electric cylinder, a linear module, or a cylinder driven by compressed air after being compressed by an air pump. In other words, the linear motion unit 3 proposed in this embodiment is existing known technology and will not be described in detail here.

[0047] In this design, a chamber 2 is provided on the clamp 1, and a first opening 21 is provided on the chamber 2 corresponding to the position of the rear camera of the terminal to be tested 8. When the terminal to be tested 8 is placed on the clamping part 11, the rear camera can capture images of the interior of the chamber 2 through the first opening 21, thereby providing space to set a first identifier 6 for detecting the rear camera's shooting function or scanning function. The first identifier 6 can be an image and / or color swatch for detecting the shooting function, or a barcode and / or QR code for detecting the scanning function, or an identifier code with specific information, such as a barcode and / or QR code.

[0048] Furthermore, the linear motion unit 3 drives the label plate 4 into or out of the shooting area, thus providing a carrier for setting the second label 7. This enables the detection of the scanning or shooting function of the rear camera without moving the terminal to be tested. When the first label 6 is an image for detecting the shooting function, the second label 7 can be a barcode and / or a QR code. When the first label 6 is a barcode and / or a QR code, the second label 7 can be an image for detecting the shooting function and / or a color swatch.

[0049] It should be further noted that, in this embodiment, the color plate can be divided into a single-color plate or a multi-color plate depending on the number of colors on the plate, and can also be divided into an active light-emitting plate and a non-light-emitting plate depending on whether it can actively emit light.

[0050] That is, on the same testing device, both the shooting function of the rear camera of the terminal under test 8 and the scanning function of the rear camera of the terminal under test 8 can be detected.

[0051] Furthermore, in this embodiment, the second identifier 7 can be an independent component connected to the identifier plate 4, or the identifier plate 4 can be the second identifier 7 itself. When the identifier plate 4 is the second identifier 7, the identifier plate 4 is preferably a monochrome plate.

[0052] Furthermore, such as Figure 3 As shown, the fixture proposed in this embodiment also includes a supplementary light 5, which is disposed in the chamber 2. By setting the supplementary light 5, it is also possible to detect the clarity of the images captured by the rear camera or the accuracy of reading the identification code under different brightness environments.

[0053] Furthermore, to ensure that the depth of chamber 2 is sufficient to guarantee the clarity of the rear camera image or the accuracy of reading the identification code, such as... Figures 1 to 5As shown, in this embodiment, to facilitate the replacement of the first identifier 6, the clamping part 11 includes a main body 111 and an open box 114. The first opening 21 is located on the main body 111, and the open box 114 is located below the main body 111 and connected to the main body 111. To facilitate the connection between the open box 114 and the clamping part 11, a connecting plate 12 can also be provided, with the clamping part 11 and the open box 114 respectively located on opposite sides of the connecting plate 12. The connecting plate 12 has a through hole 22 communicating with the first opening 21, and the opening of the open box 114 is connected to the first opening 21 through the through hole 22. To prevent dust from entering the chamber, a light-transmitting sheet (not shown) adapted to the size of the first opening 21 is provided inside the first opening 21. The light-transmitting sheet can be glass or light-transmitting plastic, etc. To make the fixture proposed in this embodiment more convenient and quick to use, a base plate 13 can also be provided. After the clamping part 11, the connecting plate 12 and the open box 114 are connected in sequence, the base plate 13 is connected through the connecting plate 12 and / or the open box 114. When using the fixture proposed in this embodiment, a snap-fit ​​groove matching the base plate 13 is provided in the terminal detection device, and the base plate 13 is directly snapped into the snap-fit ​​groove for quick engagement.

[0054] Furthermore, in this embodiment, as Figures 1 to 5 As shown, the linear motion unit 3 is mounted on the connecting plate 12 in the fixture 1. Correspondingly, to facilitate the movement of the linear motion unit 3 to drive the second marker 7 into or out of the chamber 2 formed by the first opening 21, the through hole 22, and the open box 114, a second opening 23 is provided at the connection between the open box 114 and the main body 111. The marker 4 is driven by the linear motion unit 3 to enter / exit the shooting area from the second opening 23. By setting the second opening 23, the linear motion unit 8 and / or the marker 4 can be set up more conveniently.

[0055] The second opening 23, which allows the marking plate 4 to enter or exit the shooting area in the chamber 2, can be located at the connection between the clamping part 11 and the connecting plate 12, or it can be located at the connection between the connecting plate 12 and the open box 114. That is, the second opening 23 proposed in this embodiment is located between the bottom of the open box 114 and the first opening 21.

[0056] It should be noted that in this embodiment, the second opening 23 for the identification plate 4 to enter or exit the chamber 2 is described as being located between the bottom of the open box 114 and the first opening 21. In reality, the second opening 23 can also be located on the wall of the first opening 21, or on the wall of the through hole 22. That is, the purpose of setting the opening is to ensure that the linear motion unit 3 can drive the identification plate 4 into the chamber 2, or out of the chamber 2.

[0057] It should also be noted that in this embodiment, a second opening 23 is provided on the wall of the chamber 2. The linear motion unit 3 drives the marker plate 4 to enter or exit the shooting area through the second opening 23. In fact, when the chamber 2 is large enough, the linear motion unit 3 and the marker plate can be directly placed in the chamber 2, in which case there is no need to provide the second opening 23.

[0058] Furthermore, in this embodiment, in order to fix and clamp the terminal 8 to be tested, such as... Figures 1 to 5 As shown, the clamping part 11 also includes a pressure ring 112, wherein the pressure ring 112 is connected to the main body 111, and the pressure ring 112 is located above the main body 111. The connection method includes, but is not limited to, snap-fit, detachable connection, hinge, etc.

[0059] Furthermore, in this embodiment, to better protect the terminal 8 to be tested, the clamping part 11 also includes a flexible member 113. The flexible member 113 is disposed on the pressure ring 112 and located between the pressure ring 112 and the terminal 8 to be tested. The flexible member 113 is used to protect the screen side of the terminal 8 to be tested. Specifically, it can be a rubber member or a silicone member, etc. The flexible member 113 is fixedly connected to the pressure ring 112. In actual use, the terminal 8 to be tested is first placed on the main body 111, and then the terminal 8 to be tested is fixed by the pressure ring 112 and the flexible member 113.

[0060] Furthermore, in this embodiment, the pressure ring 112 and the main body 111 are preferably connected by a hinge, and the pressure ring 112 is rotatable relative to the main body 111 with the hinge as the fulcrum.

[0061] It should also be noted that in this embodiment, the clamping part 11 fixes the terminal to be tested 8 placed on the main body 111 by the pressure ring 112 and the flexible part 113. In fact, the terminal to be tested 8 can also be fixed by means such as adsorption. For example, adsorption holes are provided on the main body 111. After the terminal to be tested 8 is placed on the main body 111, negative pressure is applied to the adsorption holes to fix the terminal to be tested 8. That is, the function of the clamping part 11 proposed in this embodiment is to fix and clamp the terminal to be tested 8.

[0062] As a second aspect of the embodiment, a terminal detection device is proposed, including the fixture described above.

[0063] It also includes a control unit, which is electrically connected to the linear motion unit 3 and the terminal to be tested 8 placed on the clamping part 11.

[0064] It should be noted that in this embodiment, the control unit refers to a digital computing electronic system, also known as a programmable logic controller, such as a PLC, microcontroller, or industrial control computer. Therefore, the control unit described in this embodiment is existing known technology and will not be described in detail here.

[0065] As a third aspect of this embodiment, a terminal detection method for the terminal detection device described above is proposed, wherein a first mark 6 is provided on the inner bottom surface of the chamber 2 opposite to the first opening 21, and a second mark 7 is provided on the mark plate 4. The mark plate 4 is located outside the shooting area in a first state, and the second mark 7 on the mark plate 4 is located within the shooting area in a second state. The specific detection steps are as follows:

[0066] Step 1: Enter the first original information of the first identifier 6 and the second original information of the second identifier 7 into the control unit;

[0067] Step 2: In the first state, the control unit generates a first instruction and sends the first instruction to the terminal to be tested 8 placed on the clamping part 11;

[0068] The terminal to be tested 8 receives and executes the first instruction, controls the rear camera to take a picture of the first identifier 6, generates the first image information, and feeds the first image information back to the control unit;

[0069] After receiving the first image information, the control unit compares the received first image information with the first original information. If they match, the detection result is qualified; otherwise, the detection result is unqualified.

[0070] Step 3: The control unit generates a second instruction and sends the second instruction to the linear motion unit 3. The linear motion unit 3 receives and executes the second instruction, causing the second identifier 7 to move from the first state to the second state.

[0071] Step 4: In the second state, the control unit generates a third instruction and sends the third instruction to the terminal to be tested 8 placed on the clamping part 11;

[0072] The terminal to be tested 8 receives and executes the third instruction, controls the rear camera to take a picture of the second identifier 7, generates second image information, and feeds back the second image information to the control unit;

[0073] After receiving the second image information, the control unit compares the received second image information with the second original information. If they match, the detection result is qualified; otherwise, the detection result is unqualified.

[0074] It should be noted that when the first identifier 6 is an active luminous identifier, the detection in step 2 should be understood as the rear camera taking a picture to generate the first image information only when the active luminous identifier is luminous; correspondingly, when the second identifier 7 is an active luminous identifier, the detection in step 4 should be understood as the rear camera taking a picture to generate the second image information only when the active luminous identifier is luminous.

[0075] From the above, it is clear that the fixture, terminal testing equipment, and terminal testing method proposed in this embodiment have the following advantages: they enable the testing of different functions of the rear camera of the terminal 8 to be tested, which is beneficial to improving integration and has high accuracy; specifically, they are reflected in:

[0076] First, by setting a chamber 2 on the fixture 1, and setting a first opening 21 in the chamber 2 corresponding to the position of the rear camera of the terminal to be tested 8, space is provided for setting a first mark 6 for detecting the shooting function or scanning function of the rear camera; at the same time, the linear motion unit 3 drives the mark plate 4 into the shooting area, thus providing a carrier for setting a second mark 7 that is different from the first mark 6, realizing the detection of the scanning function or shooting function of the rear camera; by using the first mark 6 set on the inner bottom surface of the chamber 2 opposite to the first opening 21 and the second mark 7 on the mark plate 4 driven by the linear motion unit 3 to enter or exit the shooting area, the same testing device can detect both the shooting function and the scanning function of the rear camera of the terminal to be tested 8; furthermore, since the setting positions of the chamber 2 and the first opening 21 will not interfere with the bionic mechanism used to detect screen touch, audio, surface defects, or the button detection module used to detect side buttons, they can be integrated into the same terminal testing device, which is conducive to improving the integration of the terminal testing device.

[0077] Secondly, and further, by setting up a supplementary light 5, different lighting environments can be provided to the chamber 2 when detecting the rear camera, thereby also detecting the shooting and scanning functions of the rear camera under different lighting intensities.

[0078] Third, by setting a light-transmitting sheet inside the first opening 21, the chamber 2 becomes a sealed space, which prevents dust from entering the chamber 2 and contaminating the first mark 6 or the second mark 7, thereby improving the accuracy of the detection.

[0079] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0081] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0082] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features.

Step 4: In the second state, the control unit generates a third instruction and sends the third instruction to the terminal to be tested placed on the clamping part; The terminal to be detected receives and executes the third instruction, controls the rear camera to identify and photograph the second identifier, generates second image information, and feeds back the second image information to the control unit; After receiving the second image information, the control unit compares the received second image information with the second original information. If they match, the detection result is qualified; otherwise, the detection result is unqualified.
