However, due to the high integration of test items, this equipment has low output per hour (Units Per Hour, UPH) when performing single function testing on the camera; due to the large number of test resources on a single device, the efficiency of line change is low; and because this equipment has many unused test resources that are idle, it leads to a waste of space resources; in addition, this equipment has low flexibility and needs to be modified in batches when the test resources cannot meet the requirements.

[0082] In the disclosed embodiment, the test device may be a device for performing functional tests on electronic devices such as a camera module of a mobile phone. For example, the test device may perform dark state tests such as noise and color points, resolution tests, or whiteboard tests such as brightness, brightness uniformity, color, white balance, or stain tests on the camera module of a mobile phone before the mobile phone leaves the factory.

[0083] The base may be a carrier for carrying the movable module and the functional test module; the carrier may be a carrier for carrying the object to be tested.

[0085] The object to be tested may include but is not limited to a camera module of an electronic device; for example, the object to be tested may be a camera module of a mobile phone, or a camera module of a tablet computer, etc.

[0086] It should be noted that the specific type of the above-mentioned carrier can be set according to the actual application situation, and the embodiment of the present disclosure does not limit it. For example, the above-mentioned carrier can be a single-hole carrier, a double-hole carrier, or a three-hole carrier.

[0087] The movable module may be a component disposed on the base that enables the carrier to move between the first position and the second position; for example, the movable module may be an assembly line component that can drive the carrier to move to different test stations on the assembly line component. At least one of the carriers may be placed on the movable module; when multiple carriers are placed on the movable module at the same time, the test device may perform different functional tests on multiple objects to be tested at the same time.

[0088] The above-mentioned test station can be a fixed point position for performing functional testing on the above-mentioned object to be tested on the above-mentioned movable module; the above-mentioned functional testing module can be a component set up for performing functional tests such as resolution testing, dark state testing or whiteboard testing on the above-mentioned object to be tested.

[0089] It can be understood that each of the above-mentioned test stations is provided with one of the above-mentioned functional test modules; that is, when the above-mentioned movable module drives the above-mentioned object to be tested to move to different test stations, different functional test modules can perform different functional tests on the object to be tested.

[0090] It should be noted that the specific numbers of the above-mentioned test stations and the above-mentioned functional test modules can be set according to the actual application situation, as long as one of the above-mentioned functional test modules is set at one of the above-mentioned test stations, and the embodiments of the present disclosure do not impose any limitation thereto.

[0091] In some embodiments, Figure 3 As shown, the active module 13 may include:

[0092] A plurality of test lines 131 , each of the test lines 131 being provided with at least one carrier 12 ;

[0093] a seventh driving member 132 , fixedly connected to the test line 131 , and used for driving the movement of the carrier 12 on the test line 131 ;

[0095] In this way, by setting multiple test lines on the movable module, the testing device can perform functional tests on multiple objects to be tested at the same time, thereby better improving the efficiency of functional tests on the objects to be tested; at the same time, by setting the seventh drive member and the lifting mechanism, the movement of the carrier and the transfer of the carrier can be better realized.

[0096] Among them, the above-mentioned test line can be an assembly line for performing functional tests on the above-mentioned object to be tested; the above-mentioned seventh driving member can be a component that provides power for the movement of the carrier on the above-mentioned test line, such as a motor or a cylinder; the above-mentioned lifting mechanism can be a component that enables the above-mentioned carrier to detach from the above-mentioned test line.

[0097] Here, a plurality of the test lines may be arranged in parallel, that is, the corresponding position of each of the test stations on the test line may be the same, so that the objects to be tested on each of the test lines can be subjected to the same functional test at the test station at the same time.

[0098] In the disclosed embodiment, the seventh driving member can be controlled to drive the movement of the carrier on the test line. At the same time, after the carrier moves to the test station to complete the functional test, the carrier can be separated from the test line by the lifting mechanism. The lifting mechanism can complete the raising or lowering of the carrier by lifting and lowering the cylinder.

[0099] It should be noted that the specific number of the above test lines can be set according to the actual application situation, and the embodiment of the present disclosure does not limit it. For example, the above active module can be provided with two, three or four test lines.

[0100] Understandably, if Figure 3 As shown, the movable module 13 may further include a reflow line 134 arranged in parallel with the test line 131 for realizing reflow of a carrier that does not carry the object to be tested or a carrier that carries the object to be tested that needs to be retested.

[0102] The present disclosure provides a test device, which includes: a base; a carrier for carrying an object to be tested; a movable module located on the base and capable of driving the carrier to move between a first position and a second position; a plurality of test stations located between the first position and the second position and arranged at the movable module along the moving direction of the carrier; and a plurality of functional test modules, one of which is arranged at one of the test stations, for performing a functional test on the object to be tested on the carrier when the carrier moves to the position of the test station. Through the test device proposed in the present disclosure, the object to be tested is placed in the carrier on the movable module, and the carrier is driven to move between the first position and the second position by the movable module, so that the carrier can move to a plurality of test stations located between the first position and the second position, and a plurality of functional test modules on the plurality of test stations perform a functional test on the object to be tested, so that a plurality of functional tests can be performed on the object to be tested on one test device, so as to improve the efficiency of the functional test on the object to be tested, and the line change efficiency of the carrier can be improved by the movable module.

[0103] In some embodiments, in combination Figure 2 and Figure 3 As shown, the functional test module 20 may include at least one of the following:

[0104] A first testing module 21 is used to perform a resolution test on the object to be tested 10;

[0105] A second testing module 22, used for performing a dark state test on the object to be tested 10;

[0106] The third testing module 23 is used to perform a whiteboard test on the object to be tested 10 .

[0107] In this way, by setting the first test module, the second test module and the third test module, different functional tests can be performed on the test object at different test stations, so as to improve the efficiency of the functional test on the test object.

[0108] Among them, the above-mentioned first test module can be a module capable of performing a resolution test on the above-mentioned object to be tested; for example, the above-mentioned first test module can perform a far-focus or near-focus resolution test on the camera module. The above-mentioned second test module can be a module capable of performing a dark state test on the above-mentioned object to be tested; for example, the above-mentioned second test module can perform a dark state test such as noise and color dots on the camera module. The above-mentioned whiteboard test module can be a module capable of performing a whiteboard test on the above-mentioned object to be tested; for example, the above-mentioned third test module can perform a whiteboard test such as brightness, brightness uniformity, color, white balance or stain on the camera module.

[0110] In the disclosed embodiment, the first test module, the second test module and the third test module are all arranged at intervals, and the first test module is located between the second test module and the third test module. In this way, by arranging the first test module between the second test module and the third test module, the functional test effect of performing resolution test, dark state test or whiteboard test on the object to be tested can be better achieved.

[0111] Among them, Figure 3 As shown, the multiple test stations 14 may include: a first test station 141, a second test station 142 and a third test station 143; the first test module may be arranged opposite to the first test station 141, the second test module may be arranged opposite to the second test station 142, and the third test module may be arranged opposite to the third test station 143.

[0112] Here, the second test module and the third test module may be symmetrically arranged on both sides of the first test module; the initial heights of the second test module and the third test module may be flush, that is, both are on the same horizontal line.

[0113] It can be understood that the above-mentioned object to be tested can first undergo a dark state test at the second test station, then undergo a resolution test at the first test station, and finally undergo a white board test at the third test station; that is, the order in which the above-mentioned movable module drives the carrier to move to the test stations can be from the second test station to the first test station, and then from the first test station to the third test station.

[0114] It should be noted that the specific positions of the first test module, the second test module and the third test module can be set according to actual application conditions, as long as one functional test module is set at one test station, and the embodiments of the present disclosure do not limit this.

[0115] In one embodiment of the present disclosure, Figure 2 and Figure 3 As shown, the first test module 21 may include:

[0116] A light source movable assembly 211, located on the base 11;

[0117] The relay mirror movable assembly 212 is located on the base 11 , and is disposed between the light source movable assembly 211 and the base 11 , and is spaced apart from the light source movable assembly 211 .

[0118] In this way, the relay lens movable assembly can be arranged between the base and the light source movable assembly, so that the resolution test of the object to be tested can be better achieved.

[0119] The above-mentioned light source movable assembly may be a component capable of providing a light source for performing a resolution test on an object to be tested; and the above-mentioned relay lens movable assembly may be a component capable of providing a lens for performing a resolution test on an object to be tested.

[0120] Here, both the light source movable assembly and the relay mirror movable assembly may be arranged opposite to the first test station, and the relay mirror movable assembly is located between the light source movable assembly and the first test station.

[0121] In the disclosed embodiment, during the resolution test of the object to be tested, the light source movable component can be controlled by a pre-set control program to automatically adjust according to the object to be tested, so that the object to be tested can complete the resolution test more accurately.

[0122] In some embodiments, Figure 3 and Figure 4 As shown, the light source movable component 211 may include:

[0123] The first light source body 213 is used to provide backlight for the test chart of the object to be tested 10; the test chart is a chart used for performing a resolution test on the object to be tested 10;

[0124] A first driving member 214, connected to the first light source body 213 and the base, and used for driving the first light source body 213 to move in a direction perpendicular to the base 11;

[0125] The second driving member 215 is fixedly disposed at the central axis of the first light source body 213 , and is used to drive the first light source body 213 to rotate relative to the central axis; wherein the central axis is parallel to the first driving member 214 .

[0126] In this way, the first driving member and the second driving member can be provided to respectively drive the movement of the first light source body, so that different resolution tests on the object to be tested can be more accurately implemented.

[0127] The first light source body may be a component having a double-sided light source. The first driving member may be a component capable of driving the first light source body to move linearly; the second driving member may be a component capable of driving the first light source body to rotate; for example, both the first driving member and the second driving member may be motors or cylinders.

[0128] Exemplarily, the first driving member may be a linear motor module that can directly convert electrical energy into linear motion mechanical energy without requiring any intermediate conversion mechanism. The linear motor module has the advantages of simple structure, convenient long stroke, high acceleration, fast response and high precision.

[0129] In the disclosed embodiment, two first driving members may be arranged on the same side of the first light source body, and the two first driving members may be controlled to operate or stop working simultaneously, so as to ensure the balance of the first light source body when the first light source body is driven to move perpendicularly to the direction of the base.

[0130] It should be noted that the specific type of the first driving member can be set according to the actual application scenario, and the embodiment of the present disclosure does not limit it.

[0131] In one embodiment of the present disclosure, Figure 3 and Figure 4 As shown, the light source movable component 211 may also include:

[0132] The adjusting member 216 is connected between the first driving member 214 and the first light source body 213 , and is used to adjust the first light source body 213 to be parallel to the base 11 when the first driving member 214 drives the first light source body 213 to move.

[0133] In this way, an adjustment member can be set between the first driving member and the first light source body, so that when the first driving member drives the first light source body to move perpendicular to the direction of the base, the parallelism of the first light source body and the base can be better ensured, thereby avoiding damage to the first light source body when the first driving member works asynchronously.

[0134] The above-mentioned centering joint may be a component capable of adjusting the movable space of the above-mentioned first light source body; for example, the above-mentioned adjusting component may be a centering bearing or a movable connecting rod.

[0135] That is to say, when the first driving member drives the first light source body to move in a direction perpendicular to the base, the movable space between the first light source body and the first driving member can be adjusted by the adjusting member so that the first light source body can be parallel to the base, thereby avoiding damage to the first light source body when the first driving member works asynchronously.

[0136] It should be noted that the specific number of the above-mentioned adjusting members can be set according to the actual application situation, as long as the number of the above-mentioned adjusting members is the same as the number of the above-mentioned first driving members, and the embodiment of the present disclosure does not limit it.

[0137] It can be understood that during the resolution test of the above-mentioned object to be tested, the above-mentioned first driving member and the above-mentioned second driving member can be controlled by a pre-set control program to automatically adjust the first light source body to adapt to the position of the above-mentioned object to be tested, thereby being able to complete the resolution test of the above-mentioned object to be tested more accurately.

[0138] It should be noted that the light source and the test chart used for the far-focus test or the near-focus test of the above-mentioned object to be tested are not the same; that is, in the present disclosure, the light source and the test chart used when performing different resolution tests on the object to be tested can be changed by the above-mentioned first driving member and the above-mentioned second driving member.

[0139] For example, when performing a far focus test on the object to be tested, the far focus test can be performed on the object to be tested through the first light source board of the first light source body; when performing a near focus test on the object to be tested, the near focus test can be performed on the object to be tested through the second light source board of the first light source body; and so on.

[0140] Specifically, in one embodiment of the present disclosure, Figure 3 and Figure 5 As shown, the first light source body 213 may include:

[0141] The box body 2131 is fixedly connected to the first driving member 214 and the second driving member 215;

[0142] A first light source plate 2132 is located on a surface of the box body 2131 facing the base 11;

[0143] A second light source plate 2133 is located on a surface of the box body 2131 away from the base 11;

[0144] When the first driving motor 215 drives the first light source body 213 to rotate, the second light source plate 2133 faces the base 11 .

[0145] In this way, by respectively arranging the first light source board and the second light source board on two opposite surfaces of the box body, it is possible to better adapt to different resolution tests on the object to be tested.

[0146] Among them, the above-mentioned box body can be a substrate for setting the above-mentioned first light source board and the above-mentioned second light source board; the above-mentioned first light source board can be a light source used for performing a far-focus test on the above-mentioned object to be tested; the above-mentioned second light source board can be a light source used for performing a near-focus test on the above-mentioned object to be tested.

[0147] Here, the size of the first light source board and the size of the second light source board may be the same, and the surfaces of the first light source board and the second light source board contacting the box body may overlap, so as to ensure the overall beauty of the first light source body.

[0148] It should be noted that the specific order of performing a far focus test or a near focus test on the above-mentioned object to be tested can also be set according to the actual application scenario, and the embodiments of the present disclosure are not limited. For example, in the present disclosure, the above-mentioned object to be tested can be subjected to a far focus test first, and then a near focus test. At this time, the initial position of the above-mentioned first light source board can be on the surface of the above-mentioned box body facing the above-mentioned base, and the initial position of the above-mentioned second light source board can be on the surface of the above-mentioned box body away from the above-mentioned base; or, in the present disclosure, the above-mentioned object to be tested can be subjected to a near focus test first, and then a far focus test. At this time, the initial position of the above-mentioned first light source board can be on the surface of the above-mentioned box body away from the above-mentioned base, and the initial position of the above-mentioned second light source board can be on the surface of the above-mentioned box body facing the above-mentioned base.

[0149] In one embodiment of the present disclosure, Figure 3 and Figure 5 As shown, the light source movable component 211 may also include:

[0150] A first transparent cover plate 2134 is movably connected to one side of the box body 2131 and can cover the first light source plate 2132;

[0151] A first test chart 2135, located between the first transparent cover plate 2134 and the first light source plate 2132;

[0152] A second transparent cover plate 2136 is movably connected to the other side of the box body 2131 and can cover the second light source plate 2133;

[0153] A second test chart 2137, located between the second transparent cover plate 2136 and the second light source plate 2133;

[0154] The moving direction of the first transparent cover plate 2134 is opposite to the moving direction of the second transparent cover plate 2136 .

[0155] In this way, by setting a first test chart between the first transparent cover plate and the first light source board, and setting a second test chart between the second transparent cover plate and the second light source board, different test charts can be replaced more cleverly when performing different resolution tests on the test object.

[0156] The first transparent cover plate may be a component for fixing the first test chart; the second transparent cover plate may be a component for fixing the second test chart; for example, both the first transparent cover plate and the second transparent cover plate may be glass cover plates or plastic transparent cover plates. The first test chart may be a chart used for performing a far focus test on the object to be tested; the second test chart may be a chart used for performing a near focus test on the object to be tested.

[0157] It can be understood that the moving direction of the first transparent cover plate is set to be opposite to the moving direction of the second transparent cover plate. When the second driving member drives the first light source body to rotate so that the first light source board or the second light source board is located on the surface of the box body away from the base, the user can more conveniently replace the first test card or the second test card through the moving direction of the first transparent cover plate or the second transparent cover plate, so as to better realize different resolution tests on the test object.

[0158] It should be noted that the size of the first test chart can be smaller than or equal to the size of the first light source board; similarly, the size of the second test chart can also be smaller than or equal to the size of the second light source board. The size of the first test chart can be the same as or different from the size of the second test chart, which can be set according to the actual application scenario and is not limited in the embodiments of the present disclosure.

[0159] In addition, the content of the first test chart and the content of the second test chart may be the same or different, and may be set according to the actual application scenario, which is not limited by the embodiments of the present disclosure. For example, the first test chart may have n*n black and white grids, and the second test chart may also have n*n black and white grids.

[0160] In the present disclosure, Figure 5As shown, the light source movable assembly 211 may further include: a support rod 2111, connected between the first transparent cover plate 2134 and the box body 2131 and between the second transparent cover plate 2136 and the box body 2131, and used to fix the opening angle of the first transparent cover plate 2134 and the second transparent cover plate 2136; a hinge 2112, fixedly connecting the first transparent cover plate 2134 and the box body 2131 and the second transparent cover plate 2136 and the box body 2131, and used to realize the opening and closing of the first transparent cover plate 2134 and the second transparent cover plate 2136; The limiting member 2113 is arranged on a side of the box body 2131 opposite to the hinge 2112, and is used to mark the placement direction of the first test card 2135 and the second test card 2137 to prevent the first test card 2135 and the second test card 2137 from being installed reversely; the tower buckle 2114 is arranged on the box body 2131, and is spaced apart from the support rod 2111, and is not located on the same side of the box body 2131 as the hinge 2112 and the limiting member 2113, and is used to buckle the first transparent cover plate 2134 and the second transparent cover plate 2136.

[0161] The position-limiting member may be an anti-stuck pin, which can prevent the first test chart card installed between the first light source board and the first transparent cover from being installed upside down, and can also prevent the second test chart card installed between the second light source board and the second transparent cover from being installed upside down.

[0162] It should be noted that the specific numbers of the above-mentioned support rods, hinges, limiters and tower buckles can be set according to the actual application scenario, and the embodiments of the present disclosure are not limited thereto.

[0163] In some embodiments, Figure 2 and Figure 6 As shown, the relay mirror movable assembly 212 may include:

[0164] A first bracket 2121 is fixedly connected to the base 11 and is provided with a first sliding groove 2127 in a first direction F1;

[0165] The first sliding member 2122 is at least partially located in the first sliding groove 2127 and is slidably connected to the first sliding groove 2127; the first sliding member 2122 is provided with a second sliding groove 2128 in a second direction F2;

[0166] The second sliding member 2123 is at least partially located in the second sliding groove 2128 and is slidably connected to the second sliding groove 2128;

[0167] The relay mirror body 2124 is disposed on the second sliding member 2123;

[0168] A third driving member 2125 is fixedly connected to the first sliding member 2122 and is used to drive the relay mirror body 2124 to move in the first direction F1;

[0169] a fourth driving member 2126, fixedly connected to the second sliding member 2123, and configured to drive the relay mirror body 2124 to move in the second direction F2;

[0170] The first direction F1 is perpendicular to the second direction F2 , and both the first direction F1 and the second direction F2 are parallel to the base 11 .

[0171] In this way, through the sliding connection between the first sliding member and the first sliding groove and the sliding connection between the second sliding member and the second sliding groove, it can be achieved that the third driving member can drive the relay lens body to move in the first direction, and the fourth driving member can drive the relay lens body to move in the second direction, so as to better adapt to different resolution tests on the test object.

[0172] The first bracket may be a component supporting the relay mirror body; the first sliding member and the second sliding member may be components connected between the first bracket and the relay mirror body and capable of moving. The third driving member and the fourth driving member may be components capable of driving the relay mirror body to move; for example, the third driving member and the fourth driving member may be motors or cylinders.

[0173] Here, the relay lens body can be a relay lens. The relay lens usually consists of two groups of lenses installed in a lens barrel. The lenses can be ordinary spherical lenses or aspherical lenses. The two groups of lenses are composed of at least two paired lenses or two paired lens groups. Although it is called a relay lens, it is not a lens.

[0174] Exemplarily, taking the plane where the base is located as the XY plane, the first direction may be the X-axis direction, the second direction may be the Y-axis direction, the second drive motor may be an X-axis lead screw motor, and the third drive motor may be a Y-axis linear motor.

[0175] In the embodiment of the present disclosure, when a far-focus test is performed on the object to be tested, the relay mirror body is arranged relative to the test station under the driving action of the third driving member and the fourth driving member; when a near-focus test is performed on the object to be tested, the relay mirror body can be offset from the test station under the driving action of the third driving member and the fourth driving member.

[0176] It can be understood that, in the case of performing a far focus test on the above-mentioned object to be tested, the above-mentioned third driving member and the above-mentioned fourth driving member can be used to drive the above-mentioned relay mirror body to be aligned with the above-mentioned object to be tested located at the first testing station, so that the far focus test can be performed on the object to be tested through the above-mentioned first light source board and the above-mentioned relay mirror body; in the case of performing a near focus test on the above-mentioned object to be tested, the above-mentioned third driving member and the above-mentioned fourth driving member can be used to drive the above-mentioned relay mirror body away from the above-mentioned object to be tested located at the first testing station, so that the near focus test can be performed on the object to be tested only through the above-mentioned second light source board.

[0177] It should be noted that if Figure 6 As shown, a relay lens adapter plate 2129 may also be provided on the second sliding member 2123. The relay lens adapter plate 2129 is spaced apart from the relay lens body 2124 so as to be able to replace relay lenses of different focal lengths, thereby better adapting to different camera modules.

[0178] In one embodiment of the present disclosure, Figure 2 , Figure 3 and Figure 7 As shown, the second test module 22 may include:

[0179] A second bracket 221, fixedly connected to the base 11;

[0180] A test substrate 222, disposed on the second bracket 221, for performing a dark state test on the object to be tested 10;

[0181] The fifth driving member 223 is fixedly connected to the second bracket 221 , and is used for driving the testing substrate 222 to move in a direction perpendicular to the base 11 .

[0182] In this way, the fifth driving member can be provided to adjust the movement of the test substrate in a direction perpendicular to the base, so as to adjust the distance between the test substrate and the object to be tested to a suitable distance, thereby more accurately implementing dark state testing of the object to be tested.

[0183] Among them, the above-mentioned second bracket can be a component supporting the above-mentioned test substrate; the above-mentioned test substrate can be a component for performing dark-state testing on the test object, for example, a black rough plastic plate, etc.; the above-mentioned fifth driving member can be a linear motor module that can directly convert electrical energy into linear motion mechanical energy.

[0184] Here, the specific material of the test substrate can be set according to the actual application scenario, and the embodiment of the present disclosure does not limit it. For example, the material of the test substrate can be dark sheet metal or other diffuse reflective materials.

[0185] It can be understood that when a plurality of test lines are provided in the movable module, a plurality of test substrates may be provided on the second bracket, so that a dark state test can be performed on the test object at the second test station at each test line.

[0186] Further, in the embodiments of the present disclosure, if Figure 3 and Figure 7 As shown, the second test module 22 may further include:

[0187] The diffuse reflection substrate 224 is disposed on the surface of the test substrate 222 facing the base 11 ; the diffuse reflection substrate 224 is made of a light absorbing material.

[0188] In this way, the accuracy of dark-state testing of the object to be tested can be improved by arranging a diffuse reflection substrate on the surface of the test substrate facing the base.

[0189] In the disclosed embodiment, the diffuse reflection substrate may be an object with diffuse reflection properties; for example, the diffuse reflection substrate may be black velvet. Diffuse reflection is a phenomenon in which light projected on a rough surface can be reflected in all directions. The diffuse reflection phenomenon can be used to more accurately perform dark state testing on a test object such as a camera module.

[0190] In some embodiments, Figure 2 , Figure 3 and Figure 7 As shown, the third test module 23 includes:

[0191] A third bracket 231 is fixedly connected to the base 11;

[0192] A second light source body 232 is disposed on the third bracket 231 and is used to perform a whiteboard test on the object to be tested 10;

[0193] The sixth driving member 233 is fixedly connected to the third bracket 231 , and is used for driving the second light source body 232 to move in a direction perpendicular to the base 11 .

[0194] Thus, the sixth driving member can be provided to adjust the movement of the second light source body in a direction perpendicular to the base, so that the distance between the second light source body and the object to be tested can be adjusted to a suitable distance, thereby more accurately implementing whiteboard testing of the object to be tested.

[0195] Among them, the above-mentioned third bracket can be a component supporting the above-mentioned second light source body; the above-mentioned second light source body can be a component for performing a whiteboard test on the test object; the above-mentioned sixth driving component can be a linear motor module that can directly convert electrical energy into linear motion mechanical energy.

[0196] Here, the specific type of the second light source body can be set according to the actual application scenario, and the embodiment of the present disclosure does not limit it. For example, the second light source body can be a whiteboard light source, etc.

[0197] It can be understood that when a plurality of test lines are provided in the movable module, a plurality of second light source bodies may be provided on the third bracket, so that a whiteboard test can be performed on the test object at the third test station at each test line.

[0198] It should be noted that the sixth driving member and the fifth driving member may be the same or different, and the initial position of the second light source body relative to the base controlled by the sixth driving member and the initial position of the dark state substrate relative to the base controlled by the fifth driving member may also be the same or different, and the embodiments of the present disclosure do not impose any restrictions thereon.

[0199] Exemplarily, in an embodiment of the present disclosure, after the camera module of the object to be tested, such as a mobile phone, is placed in the carrier, the movable module can drive the carrier to move so as to move the camera module to the location of the second test station. At this time, the distance between the camera module and the test substrate can be adjusted by the lifting mechanism of the movable module and the fifth driving member of the second test module to perform a dark-state test on the camera module; after completing the dark-state test on the camera module, the lifting mechanism can lower the carrier to the test line of the movable module, and then move the carrier to the location of the first test station through the movable module. At this time, the distance between the camera module and the relay mirror body can be adjusted by the lifting mechanism and the third driving member and the fourth driving member in the relay mirror movable assembly, and at the same time, the first light source board in the light source movable assembly is arranged relative to the camera module to perform a telefocus test on the camera module; after completing the dark-state test on the camera module After the far-focus test of the group, the second driving member in the light source movable assembly can drive the first light source body to rotate, so that the second light source board can be arranged opposite to the camera module, and then the relay lens body is moved away by the third driving member and the fourth driving member to make the relay lens body away from the camera module. At this time, the camera module can be tested for near focus; after completing the near-focus test of the camera module, the lifting mechanism can lower the carrier to the test line of the movable module, and then move the carrier to the location of the third test station through the movable module. At this time, the distance between the camera module and the second light source body can be adjusted by the lifting mechanism and the third driving member of the whiteboard test module to perform a whiteboard test on the camera module, thereby completing three different functional tests of the camera module in the test device disclosed in the present invention, so as to improve the efficiency of functional testing of the camera module, and the line changing efficiency of the carrier can be improved through the movable module.
