DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] refer to Figure 1 and Figure 2 The camera test fixture in the embodiment of the utility model can be used to perform a silent test on a camera product. Specifically, the camera test fixture may include a test base 100 and a test adapter plate 200, wherein the test base 100 includes a test bottom plate 110 and a product placement carrier plate 120, and the test adapter plate 200 and the product placement carrier plate 120 are both installed on the test bottom plate 110.

[0024] The test adapter board 200 is provided with a plurality of test connection points 210, where the test connection points 210 can be understood as structures in the prior art that are directly in contact and connected with the test product 10, so that the test product 10 is connected to the test adapter board 200 through the test connection points 210. The product placement carrier board 120 is used to place the test product 10, and the product placement carrier board 120 is provided with a plurality of groups of test probe modules 300 corresponding to the plurality of test connection points 210, and each test connection point 210 can be connected to a group of test probe modules 300 through a transfer wire 600. The test adapter board 200 can also be connected to the test equipment through a data line to transmit data.

[0025] The number of the test probe modules 300 is the same as the number of the test connection points 210 , and the arrangement of the multiple groups of test probe modules 300 is the same as the arrangement of the multiple test connection points 210 , so that the test product 10 can be contacted and connected with the multiple groups of test probe modules 300 one by one.

[0026] Furthermore, if Figure 1 As shown, the product placement carrier 120 is also provided with a connection terminal 400 and a positioning module 500. The connection terminal 400 is connected to the test equipment. When the test product 10 is placed on the product placement carrier 120, the test product 10 can be connected to the connection terminal 400, so that the test product 10 is connected to the test equipment. At this time, the test product 10 can obtain power from the test equipment, so that it can be turned on for subsequent testing. The positioning module 500 can be used to position the test product 10 placed on the product placement carrier 120 to ensure that the test product 10 is placed in place, so that the test product 10 can be accurately connected to the multiple groups of test probe modules 300 and the connection terminal 400, and the accuracy of the test results of the test product 10 is ensured.

[0027] In some embodiments, reference is made to Figure 3 and Figure 4 The test probe module 300 may include a needle mold 310 and a test probe 320 installed on the needle mold 310. The product placement carrier 120 is provided with limiting grooves 121 corresponding to multiple groups of test probe modules 300. Each needle mold 310 is installed in the corresponding limiting groove 121. The limiting groove 121 can limit the limiting groove 121 to ensure that the needle mold 310 will not be displaced in the limiting groove 121.

[0028] There are one or more test probes 320 installed on each needle mold 310. In specific implementation, the number of test probes 320 can be designed according to the requirements of the test product 10. For example, the needle mold 310 can be provided with a probe hole 311 corresponding to the test probe 320. The probe hole 311 can penetrate the needle mold 310 along the depth direction of the limiting groove 121, and the test probe 320 is inserted into the probe hole 311. In addition, as mentioned above, the test connection point 210 on the test adapter board 200 is connected to the test probe module 300 through the adapter wire 600. A probe contact point can be set at the bottom of the limiting groove 121. The adapter wire 600 is connected to the probe contact point. When the needle mold 310 is placed in the limiting hole, one end of the test probe 320 can be connected to the probe contact point, thereby realizing the connection between the test probe 320 and the test connection point 210. The other end of the test probe 320 protrudes from the surface of the needle mold 310, so as to facilitate contact and connection with the test product 10.

[0029] In this embodiment, the test probe 320 is detachably connected to the needle mold 310. When the test probe 320 is damaged, the test probe 320 can be removed from the needle mold 310 and replaced with a new test probe 320, which can save costs. As an optional implementation scheme, the test probe 320 and the probe hole 311 are interference fit, which can be understood as when the test probe 320 is inserted into the probe hole 311, the test probe 320 and the probe hole 311 can remain relatively fixed without external interference. When the test probe 320 needs to be replaced, the test probe 320 can be pulled out of the probe hole 311 of the needle mold 310 using an installation tool, and then a new test probe 320 can be inserted into the probe hole 311.

[0030] In addition, the needle mold 310 and the limiting groove 121 are also detachably connected. When the probe needs to be replaced, the needle mold 310 and the test probe 320 are removed from the limiting groove 121, which is convenient for the operator to replace the test probe 320. The needle mold 310 and the limiting groove 121 can be installed in the limiting groove 121, for example, by locking screws to ensure that the needle mold 310 and the limiting groove 121 remain relatively fixed, so as to avoid the shaking of the needle mold 310 during multiple tests and affect the position of the test probe 320. When the needle mold 310 needs to be removed from the limiting groove 121, the locking screws are removed, and then the needle mold 310 is taken out, which is simple and easy to implement.

[0031] It can be understood that in this embodiment, the test product 10 is connected to the test adapter board 200 by connecting to the test probe 320, so as to facilitate the subsequent silent test. Since the test probe 320 is for professional testing and has a long service life, it can ensure stable signal transmission during the test, thereby improving the test efficiency and the accuracy of the test results.

[0032] Continue to refer Figure 1 and Figure 2 The positioning module 500 includes a plurality of positioning blocks 510, a plurality of positioning columns 520, a limit block 530 and a fixing clamp 540. The plurality of positioning blocks 510 are distributed at intervals along the circumferential direction of the shape contour of the test product 10. For example, the test product 10 in this embodiment is a circular camera, and the plurality of positioning blocks 510 are distributed along the circumferential direction. The plurality of positioning blocks 510 can be enclosed to form a positioning area, and the positioning area is used to place the test product 10. When the test product 10 is placed in the positioning area, each positioning block 510 contacts the side of the test product 10 respectively, thereby pre-positioning the test product 10. The positioning block 510 is an arc-shaped structure to ensure that when the positioning block 510 contacts the surface of the test product 10, the positioning block 510 can fit the surface of the test product 10, thereby ensuring the positioning effect.

[0033] The plurality of positioning posts 520 are located in the positioning area surrounded by the plurality of positioning blocks 510, and the plurality of positioning posts 520 may also be distributed at intervals along the circumference of the test product 10. When the test product 10 is placed in the positioning area, each positioning post 520 may extend into the positioning hole provided in the test product 10, thereby achieving accurate positioning of the test product 10.

[0034] The limit block 530 is located in the positioning area surrounded by the plurality of positioning blocks 510, and a slot is provided on the side of the test product 10, and the opening of the slot is located at the bottom of the test product 10. When the test product 10 is placed in the positioning area, the limit block 530 can extend into the slot from the bottom of the slot and abut against the bottom of the slot. At this time, the limit block 530 and the slot are relatively fixed, and the test product 10 can be further accurately positioned.

[0035] The fixing clamp 540 is installed on the product placement carrier 120. A pressing block 541 is provided at one end of the fixing clamp 540. The fixing clamp 540 can rotate relative to the product placement carrier 120 to drive the pressing block 541 to rotate. When the test product 10 is placed on the product placement carrier 120, the fixing clamp 540 can be rotated so that the pressing block 541 is pressed against the side surface of the test product 10 away from the product placement carrier 120, thereby limiting the position of the test product 10. When the test is completed, the fixing clamp 540 is rotated again so that the pressing block 541 is separated from the side surface of the test product 10 away from the product placement carrier 120, so as to facilitate the removal of the test product 10.

[0036] In this embodiment, the positioning block 510, the positioning column 520 and the limiting block 530 can cooperate to limit the test product 10 in the horizontal direction, and the fixing clamp 540 can be used to limit the test product 10 in the vertical direction. Through the limiting effect of the above structures, it can ensure that the test product 10 is accurately positioned before the test, and ensure that the test product 10 remains stationary during the test, thereby ensuring the stability of signal transmission and improving the accuracy of the test results.

[0037] Based on the same design concept, the embodiment of the utility model can also provide a camera testing system, which may include a testing device, a barcode reading device and a camera testing fixture as described in the above embodiment, wherein the testing device may be, for example, a computer. The barcode reading device may be, for example, a barcode gun, which can be used to read the barcode of the test product 10 and enter the barcode into a computer or a cloud server to facilitate the traceability of the product later. The test adapter board 200 of the camera testing fixture is connected to the testing device to transmit the signal data obtained from the test product 10 to the testing device, and the testing device performs a test based on the obtained data to determine whether the performance of the test product 10 is good. The testing device can also power the test product 10 through the connection terminal 400 on the product placement carrier 120 to ensure that the test product 10 can be powered on for testing.

[0038] Based on the camera test fixture and camera test system introduced in the above embodiments, when performing a silent test on a camera, the following steps may be referred to:

[0039] Step 1: Place the test product 10 on the product placement carrier 120 and rotate the fixing clip 540 so that the fixing clip 540 is pressed against the test product 10;

[0040] Step 2: After the test product 10 contacts the connection terminal 400, it is automatically powered on and connected to the test equipment. The barcode on the test product 10 is read by a barcode reader, and then the test software on the test equipment is clicked to start the test;

[0041] Step 3: The test software controls the test product 10 to complete various tests;

[0042] Step 4: Remove the tested product 10. At this point, the test is completed.

[0043] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
