[0063] The application will be further described below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are intended to be merely illustrative of the application and not in limitation thereof. It should also be understood that, for the purpose of clarity, only those structures of the application that are relevant to the present application have been shown in the drawings.
[0064] In the description of the present application, unless otherwise explicitly specified and limited, the terms "connected", "connected", "fixed" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0065] In the present application, unless otherwise explicitly specified and limited, the first feature "on" or "under" the second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, the first feature "on", "above" and "above" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "below" and "below" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.
[0066] In the description of the embodiments, the terms "upper", "lower", "left", "right", and the like, orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description and simplification of operation, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first" and "second" are only used to distinguish in the description, and have no special meaning.
[0067] The test system provided by the embodiment mainly detects the performance of image sensors and other light-sensitive parts. The image sensor converts the light image on the light-sensitive surface into an electric signal in a corresponding proportional relationship with the light image by using the photoelectric conversion function of the photoelectric device. Compared with the photoconductive camera tube, the image sensor has the characteristics of small size, light weight, high integration, high resolution, low power consumption, long service life, low price, and the like, and therefore is widely used in various industries.
[0068] In actual application, the light source device 100 required by the traditional test system is mostly of an integrated structure. The structures of the light source devices 100 corresponding to different types of test pieces 200 are different. When the test system switches the test piece 200, the entire light source device 100 needs to be replaced. Since the entire light source device 100 has a large volume, the replacement of the light source device 100 is very cumbersome.
[0069] In order to solve the problem of cumbersome replacement of the entire light source device 100 in the traditional test system, as shown in Figure 1 The test system provided by the embodiment includes a light source device 100. The light source device 100 includes a light source assembly 1, a light emitting assembly 2, and a quick release assembly 3. The light source assembly 1 provides a light source for the test piece 200. The light emitting assembly 2 is arranged on the light emitting side of the light source assembly 1. A light transmission passage is formed in the light emitting assembly 2. One end of the light transmission passage is opposite to the light source assembly 1. The test piece 200 covers the other end of the light transmission passage away from the light source assembly 1. The light source assembly 1 and the light emitting assembly 2 are detachably connected through the quick release assembly 3.
[0070] The light source device 100 is provided with the quick release assembly 3. For different types of test pieces 200, the light emitting assembly 2 matched with the test piece 200 can be quickly replaced. The light emitting assembly 2 has a smaller volume than the entire light source device 100, which is convenient for the replacement of the operator and can greatly simplify the replacement process of the light source device 100. In addition, when one of the light source assembly 1 or the light emitting assembly 2 fails, the failed part can be removed and replaced with the spare part on the normally operating part, which can greatly reduce the maintenance cost of the light source device 100. Specifically, the quick release assembly 3 can be a buckle structure or a clasp structure. The buckle structure and the clasp structure have the characteristics of simple structure and easy assembly.
[0071] In order to be able to more specifically describe the specific structure of the light source assembly 1, as shown in Figure 2 and Figure 3 The light source assembly 1 includes a first mounting structure 11, an LED lamp group 12, and a diffusion sheet 13. The first mounting structure 11 is provided on the light-in side of the light-out assembly 2, and a first mounting hole 111 is formed in the first mounting structure 11 and faces the light-transmitting passage. The LED lamp group 12 is provided on the side of the first mounting structure 11 away from the light-out assembly 2, and the LED lamp group 12 includes LED lamp beads 121. The LED lamp beads 121 are located at one end of the first mounting hole 111, and the diffusion sheet 13 is provided at the other end of the first mounting hole 111. The light emitted from the LED lamp beads 121 passes through the first mounting hole 111 and the diffusion sheet 13 in sequence and then reaches the incident end of the light-out assembly 2. Since the diffusion sheet 13 has a certain diffusion effect on light, it can uniformly transmit the light emitted by the LED lamp beads 121 after performing a fogging effect on the light, so that the light emitted from the diffusion sheet 13 is more uniformly distributed, and no shadow of a scattering point can be seen from the emission surface of the diffusion sheet 13, thereby providing a good test light source environment for the test piece 200.
[0072] Preferably, in order to improve the diffusion effect of the light source assembly 1 on the light source, at least two diffusion sheets 13 are provided in the first mounting hole 111. Compared with the scheme of providing one diffusion sheet 13, providing at least two diffusion sheets 13 can improve the uniformity of the emitted light distribution. In addition, the at least two diffusion sheets 13 are arranged in a spaced-apart manner along the axis direction of the first mounting hole 111. In this embodiment, the two adjacent diffusion sheets 13 are arranged in a spaced-apart manner. The light can be fully refracted and reflected in the two adjacent diffusion sheets 13, so that the diffusion effect of the light is more sufficient, and the uniformity of the emitted light is improved. The greater the spacing between the two adjacent diffusion sheets 13, the better the diffusion effect of the light, the more uniform the emitted light, and a better test light source environment can be provided for the test piece 200.
[0073] In order to further improve the diffusion effect on the light, a diffuse reflection protrusion is provided on the inner wall of the first mounting hole 111. The protrusion can be formed by sandblasting the inner wall of the first mounting hole 111. The light can be diffusely reflected, thereby improving the uniformity of the light after passing through the diffusion sheet 13.
[0074] The existing light source device 100 can only provide single-color uniform light. If it is necessary to switch to other light environments, the entire light source assembly 1 needs to be replaced, which increases the test cost. In order to reduce the test cost, as shown in Figure 2As shown, the first mounting structure 11 includes a first light barrel 112, a second light barrel 113 and a quick release part 114, the LED lamp group 12 is mounted on the first light barrel 112, the diffusion sheet 13 capable of realizing different functions is mounted on different second light barrels 113, the first light barrel 112 and the second light barrel 113 mounted with the diffusion sheet 13 of different functions are detachably connected through the quick release part 114, so as to realize the function of mounting the second light barrel 113 mounted with the diffusion sheet 13 of different functions to the first light barrel 112, so that the first mounting structure 11 realizes different functions to form different light environments, without replacing the whole light source assembly 1, saving the test cost. In addition, the first light barrel 112 mounted with different types of LED lamp groups 12 can also be replaced to form different light environments, without replacing the whole light source assembly 1, saving the test cost.
[0075] In addition, since the LED lamp group 12 or the diffusion sheet 13 may fail alone during use, if the first light barrel 112 and the second light barrel 113 are fixed as a whole, the whole light source assembly 1 will be replaced after the failure of the single LED lamp group 12 or the diffusion sheet 13, increasing the maintenance cost of the light source device 100. Since the first light barrel 112 and the second light barrel 113 are detachably connected through the quick release part 114, when one of the LED lamp group 12 or the diffusion sheet 13 fails, the failed part is detached and the replaced part is mounted, greatly reducing the maintenance cost of the light source device 100. Specifically, the quick release part 114 can be a buckle structure or a clasp structure, which has the characteristics of simple structure and easy assembly.
[0076] Now, the structure of the light emitting assembly 2 will be introduced. Figure 2 The second mounting structure 21 is connected with the light source assembly 1 through the quick release assembly 3, and the test head 22 is arranged on the second mounting structure 21 and faces the diffusion sheet 13. When the light source device 100 needs to switch the tested piece 200, the second mounting structure 21 is detached from the light source assembly 1 through the quick release assembly 3, the test head 22 matched with the tested piece 200 is replaced, and the second mounting structure 21 mounted with the matched test head 22 is reinstalled on the light source assembly 1, so as to complete the replacement of the light emitting assembly 2.
[0077] In order to realize the simultaneous detection of multiple groups of tested pieces 200 at one time, the light source device 100 includes a plurality of light source assemblies 1. Figure 2 As shown, the light emitting assembly 2 includes a plurality of test heads 22, and the test heads 22 are mounted on a test head mounting plate 211 and face the diffusion sheet 13.
[0078] In the actual detection process, the to-be-detected member 200 has certain requirements for the temperature of the light source environment. In order to meet the test temperature requirements of the to-be-detected member 200, as shown in Figure 2 The second mounting structure 21 includes a test head mounting plate 211 and a heating structure 212. The test head 22 is mounted on the test head mounting plate 211. The light emitting end of the test head 22 is located on both sides of the test head mounting plate 211 with the heating structure 212. Through the temperature adjustment of the heating structure 212, the appropriate temperature can be provided for the test head 22 to meet the temperature requirements of the to-be-detected member 200. Specifically, the heating structure 212 can be an electric heating plate or a fluid heating plate, which is not limited in the present application. Any heating structure 212 capable of adjusting the temperature can be applied in the present application.
[0079] Since the light source assembly 1 is sensitive and fragile to temperature, in order to prevent the temperature generated by the heating structure 212 from damaging the light source assembly 1, as shown in Figure 2 The heating structure 212 includes a heating sheet 2121, a heating sheet cover plate 2122, and a heat insulation sheet 2123. The heating sheet 2121 is connected to the test head mounting plate 211. The heating sheet cover plate 2122 is located on both sides of the heating sheet 2121 with the test head mounting plate 211. The heat insulation sheet 2123 is arranged between the heating sheet cover plate 2122 and the light source assembly 1. The heat insulation sheet 2123 can effectively block the heat generated by the heating sheet 2121 from being transmitted to the light source assembly 1, avoiding damage to the light source assembly 1 by the heating sheet 2121, and ensuring the normal operation of the light source assembly 1. Specifically, the heat insulation sheet 2123 can be selected from mica, heat insulation foam, etc.
[0080] In the present embodiment, the heating sheet 2121 is a flat plate structure, which is simple in structure and convenient to install. In addition, the heating sheet 2121 can simultaneously heat the light passing through multiple test heads 22, which facilitates the provision of the required temperature for multiple to-be-detected members 200 at the same time, enables the heating sheet 2121 to control the temperature of multiple test heads 22 at the same time, and improves the test efficiency of the light source device 100.
[0081] Image sensors are commonly used in mobile phones for imaging functions in camera functions. Specifically, in order to realize the camera function of the mobile phone, the mobile phone includes a lens mechanism 222 and an image sensor. The external image passes through the lens mechanism 222 and is imaged by the image sensor, thereby forming a picture stored in the mobile phone. In order to provide a light environment similar to the use scene for the to-be-detected member 200, the present application is combined with Figures 2 to 4The specific structure of the test head 22 is described below. The test head 22 includes a lens mounting bracket 221 and a lens mechanism 222. The lens mounting bracket 221 has a light-transmitting hole 22122. The test piece 200 covers the light-transmitting hole 22122. The lens mounting bracket 221 is connected to the second mounting structure 21. The second mounting structure 21 has a second mounting hole 213. The lens mechanism 222 is set in the second mounting hole 213 and extends directly below the diffuser 13. The light-inlet end of the lens mechanism 222 is directly opposite to the light-outlet end of the light source assembly 1. This ensures that the light generated by the light source assembly 1 passes through the lens mechanism 222 and the light-transmitting hole 22122 and hits the test piece 200, thereby creating a light environment for the test piece 200 when the mobile phone is imaging. This makes the test results obtained under this light environment more consistent with the actual application scenario and makes the test results of the test piece 200 more accurate.
[0082] Furthermore, the lens mechanism 222 is detachably connected to the lens mounting bracket 221, thereby enabling the replacement of different models of lens mechanisms 222 to facilitate switching between different lens mechanisms 222 and changing the detection scenario. Figure 3 and Figure 5 As shown, the lens mechanism 222 includes a fixed lens 2221 and a lens adjustment seat 2222. The lens mounting bracket 221 includes a detachably connected lens cover plate 2211 and a lens mounting seat 2212. The lens mounting seat 2212 has a lens mounting cavity 22121, and the lens cover plate 2211 has a through hole 22112. The lens adjustment seat 2222 is disposed inside the lens mounting cavity 22121, and the lens 2221 extends out of the lens mounting bracket 221 through the through hole 22112. To achieve the detachable connection between the lens cover plate 2211 and the lens mounting seat 2212, the lens cover plate 2211 and the lens mounting seat 2212 are detachably connected by screws.
[0083] In order to ensure that the light emitted by the LED bead 121 is successfully projected onto the device under test 200, such as Figure 3 As shown, the lens adjustment base 2222 has through holes 22222 that are directly opposite to the lens 2221 and the light transmission hole 22122 and located between the lens 2221 and the light transmission hole 22122. The light emitted from the LED bead 121 passes through the first mounting hole 111, the diffuser 13, the second mounting hole 213, the lens 2221, the through hole 22222 and the light transmission hole 22122 in sequence, thereby shining the light onto the test piece 200.
[0084] Preferably, such as Figure 3 As shown, the LED bead 121, diffuser 13, lens mechanism 222, and light-transmitting hole 22122 are coaxially arranged, which can ensure that the light generated by the LED bead 121 is bright in the middle and dark at the edges when it reaches the test piece 200, thereby meeting the requirements of the light source environment required by the test piece 200.
[0085] However, the light source device 100 is difficult to ensure that the lens mechanism 222 is standard installed on the lens mounting frame 221 due to assembly error and other reasons during installation, and it is difficult to ensure the coaxial arrangement of the LED lamp bead 121, the diffusion sheet 13, the lens mechanism 222 and the light transmission hole 22122. In order to solve the above problems, as shown in Figure 4 and Figure 5 The test head 22 also includes an adjusting mechanism 223, which is arranged between the lens mounting frame 221 and the lens mechanism 222. The adjusting mechanism 223 is used to adjust the relative position of the lens mechanism 222 and the lens mounting frame 221, so as to ensure that the lens mechanism 222 is standard installed on the lens mounting frame 221. When the lens mechanism 222 deviates, the adjusting mechanism 223 can be used for fine adjustment, so as to ensure the coaxial arrangement of the LED lamp bead 121, the diffusion sheet 13, the lens mechanism 222 and the light transmission hole 22122.
[0086] Specifically, as shown in Figure 5 The adjusting mechanism 223 includes a first adjusting structure 2231 and a second adjusting structure 2232. The first adjusting structure 2231 is used to adjust the relative position of the lens mechanism 222 along the X direction relative to the lens mounting frame 221. The second adjusting structure 2232 is used to adjust the relative position of the lens mechanism 222 along the Y direction relative to the lens mounting frame 221. The adjusting range of the lens mechanism 222 in the horizontal plane of the lens mounting frame 221 can be ensured, and the adjustment is more convenient.
[0087] In order to more clearly describe the specific adjusting process of the first adjusting structure 2231, as shown in Figure 5 The first adjusting structure 2231 includes a first adjusting screw 22311, a first spring 22312 and a second adjusting screw 22313. The first adjusting screw 22311 is screwed on the lens mounting frame 221. The end of the first adjusting screw 22311 opposite to the lens mechanism 222 is connected with the lens mechanism 222 through the first spring 22312. The second adjusting screw 22313 is screwed on the lens mounting frame 221. The first adjusting screw 22311 and the second adjusting screw 22313 are located on both sides of the lens mechanism 222 along the X direction. When it is necessary to adjust the position of the lens mechanism 222 along the X direction relative to the lens mounting frame 221, the second adjusting screw 22313 is rotated. The first spring 22312 is stretched or released under the action of the first adjusting screw 22311 and the second adjusting screw 22313, so as to change the position of the lens mechanism 222 along the X direction relative to the lens mounting frame 221.
[0088] In order to more clearly describe the specific adjusting process of the second adjusting structure 2232, as shown in Figure 5As shown, the second adjusting structure 2232 comprises a third adjusting screw 22321, a second spring 22322 and a fourth adjusting screw 22323, the third adjusting screw 22321 is screwed on the lens mounting frame 221, the end of the third adjusting screw 22321 opposite to the lens mechanism 222 is connected with the lens mechanism 222 through the second spring 22322, the fourth adjusting screw 22323 is screwed on the lens mounting frame 221, the third adjusting screw 22321 and the fourth adjusting screw 22323 are located on both sides of the lens mechanism 222 along the Y direction. When it is needed to adjust the position of the lens mechanism 222 relative to the lens mounting frame 221 along the Y direction, the fourth adjusting screw 22323 is rotated, the second spring 22322 is stretched or released under the action of the third adjusting screw 22321 and the fourth adjusting screw 22323, thereby changing the position of the lens mechanism 222 relative to the lens mounting frame 221 along the Y direction.
[0089] In order to avoid the friction between the lens mechanism 222 and the lens mounting frame 221 during the adjustment process, thereby causing damage to the lens mechanism 222, the adjusting mechanism 223 further comprises a floating structure 2233.
