Description

Technical Field

[0001] The utility model belongs to the technical field of image storage, and in particular relates to a boost adapter plate used for camera module testing. Background Art

[0002] The camera module needs to be calibrated and tested during the production process, and the calibration data must be burned into the storage space inside the camera module. During the calibration process, external power is required for normal testing.

[0003] During the testing process, the camera module needs to be connected to the image acquisition card using an adapter board, connecting belt, etc., and the power required by the camera module is provided externally. This external power supply is generally provided by the image acquisition card. However, since the sensors used in some camera modules require an external power supply whose voltage exceeds the upper limit that the existing image acquisition card can output, it is necessary to boost the corresponding power supply on the adapter board to meet the testing requirements of the camera module, so as to avoid adding additional external power supplies (such as ordinary voltage-stabilized power supplies) or developing and introducing new test boxes, so as to save costs and facilitate the maintenance of test fixtures.

[0004] However, the image acquisition cards currently used sometimes cannot provide the voltage required for normal testing of camera modules. Developing and importing image acquisition cards that meet the requirements requires a long period of time and high costs.

[0005] In addition, adding an additional external voltage regulator also requires higher costs and increases the difficulty of maintaining the production line.

[0006] In view of this, the present utility model is proposed. Utility Model Content

[0007] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a boost adapter plate for camera module testing, thereby solving the problems raised in the above-mentioned background technology.

[0008] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0009] A boost adapter plate for camera module testing comprises: an adapter box, a box cover is provided on the top of the adapter box, a base plate is provided on the bottom of the adapter box, support blocks are fixedly connected to the four corners of the adapter box, an adapter plate is provided on the top of the support block, an acquisition card is plugged into one side of the top of the adapter plate, one end of the acquisition card is connected to the side wall of the adapter box through a data interface, two wire pulling openings are opened on the surface of the base plate, and a push plate is installed inside the wire pulling opening.

[0010] Preferably, a rotating shaft is installed through one end of the base plate, a hook is fixedly connected to the other end of the base plate, and a socket is provided at the bottom of the adapter box at a position corresponding to the hook.

[0011] Preferably, mounting blocks are fixedly connected to the four corners of the top of the adapter box, and mounting screw holes are provided at the center positions of the mounting blocks and the four supporting blocks.

[0012] Preferably, a heat dissipation port is provided on the side wall of the adapter box near the acquisition card area, a heat dissipation fan is installed inside the heat dissipation port, and a ventilation port is provided on the side wall area opposite to the heat dissipation port.

[0013] Preferably, a control software interface is provided on the side wall of the adapter box in an area between the heat dissipation opening and the ventilation opening.

[0014] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described below at the same time:

[0015] 1. The boost adapter board used in the camera module test meets the test requirements of the camera module by extending the output voltage of the existing image acquisition card. By switching back and forth between 2.8V and 4.2V voltages, there is no need to develop and import additional image acquisition cards and external voltage regulators, and it can also meet the higher voltage requirements of some camera modules.

[0016] 2. The boost adapter board used in the camera module test avoids the increase in equipment cost and maintenance difficulty caused by adding an additional voltage-stabilized power supply.

DETAILED DESCRIPTION

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] See also Figure 1-6 As shown, in this embodiment, a boost adapter plate for camera module testing is provided, including an adapter box 1, wherein a box cover 9 is provided on the top of the adapter box 1, a base plate 11 is provided at the bottom of the adapter box 1, support blocks 16 are fixedly connected to the four corners inside the adapter box 1, an adapter plate 2 is provided on the top of the support block 16, an acquisition card 3 is plugged into one side of the top of the adapter plate 2, one end of the acquisition card 3 is connected to the side wall of the adapter box 1 through a data interface 4, two wire pulling openings 14 are opened on the surface of the base plate 11, and a push plate 15 is installed inside the wire pulling opening 14.

[0031] In this embodiment, the box cover 9 and the bottom plate 11 are located at the upper and lower ends of the adapter box 1 to close the adapter box 1, and the entire adapter board 2 is placed in the adapter box 1, with the four corners suspended on the support blocks 16 to prevent the metal wiring on the adapter board 2 from contacting the adapter box 1 and causing a short circuit. The card slot at the top edge is inserted into the acquisition card 3, and the corresponding acquisition card 3 output signal interface is fitted with the data interface 4. The external line is used to output the acquisition card 3 signal, and the corresponding push plate 15 is embedded in the pull wire opening 14 through the side horizontal groove of the pull wire opening 14. The pull wire opening 14 is opened or closed by pushing the push plate 15. The adapter board 2 is connected to the external structure through the pull wire opening 14, and the other end is connected to the adapter board 2. The connecting line passes through the gap between the adapter board 2 and the side wall of the adapter box 1. There are two sets of chips on the adapter board 2 to switch the voltage required by the module.

[0032] A rotating shaft is installed through one end of the bottom plate 11 , and a hanging buckle 12 is fixedly connected to the other end of the bottom plate 11 . A socket 13 is provided at the bottom of the adapter box 1 at a position corresponding to the hanging buckle 12 .

[0033] In this embodiment, the shaft is fixed to the bottom of the adapter box 1, so that the bottom plate 11 rotates around the shaft to open or close the bottom of the adapter box 1. The hook 12 on the bottom plate 11 is inserted into the socket 13 to fix the bottom plate 11 to prevent it from detaching. The adapter plate 2 can be placed into the adapter box 1 from the bottom of the adapter box 1 at the offset support block 16, or the box cover 9 can be opened to directly place the adapter plate 2. The installation is relatively convenient.

[0034] The four corners of the top of the adapter box 1 are fixedly connected with mounting blocks 10 , and the center positions of the mounting blocks 10 and the four supporting blocks 16 are all provided with mounting screw holes.

[0035] In this embodiment, the box cover 9 is screwed into and fixed on the adapter box 1 to be closed, and the adapter plate 2 is screwed into the support block 16 to be fixed in the adapter box 1 by screws.

[0036] A heat dissipation vent 5 is provided on the side wall of the adapter box 1 near the acquisition card 3 , a heat dissipation fan 6 is installed inside the heat dissipation vent 5 , and a ventilation vent 7 is provided on the side wall opposite the heat dissipation vent 5 .

[0037] In this embodiment, the acquisition card 3 generates a lot of heat when working. The accumulated heat accumulates in the adapter box 1, causing the temperature to rise and damaging the internal components. The cooling fan 6 rotates to blow the external air into the interior of the adapter box 1 through the heat dissipation port 5 and finally blows it out from the vent 7, thereby dissipating the heat inside the adapter box 1.

[0038] A control software interface 8 is provided on the side wall of the adapter box 1 in an area between the heat dissipation opening 5 and the ventilation opening 7 .

[0039] In this embodiment, the voltage is switched by controlling the external wiring of the software interface 8 .

[0040] Working Principle: The module supplies an AVDD voltage of 2.8V when lighting up and 4.2V when programming, performing multiple cycles of rapid voltage switching between step-up and step-down. This product primarily consists of an LDO (MP20051) + Switch + STG3680 switcher + core components. When the module requires 2.8V and 4.2V voltage step-up / step-down switching during software programming, the VPP voltage is input to the two LDOs (MP20051), which then output 4.2V and 2.8V voltages to the STG3680 switcher. Software then controls the high and low levels of the AFVDD / POW pin, enabling the STG3680 to instantly output 2.8V and 4.2V to supply the module with step-up / step-down operations.

[0041] The present invention is not limited to the above-described embodiments. Any structural changes made under the guidance of the present invention should be understood by anyone. Any technical solution that is the same or similar to the present invention falls within the scope of protection of the present invention. The technology, shape, and structure not described in detail in the present invention are all known technologies.
