[0057] As described in the background art section of the specification, although the existing PCBA calibration fixture can achieve the calibration and alignment function, it does not consider functions such as anti-static, anti-fooling, convenient production turnover, and simple maintenance. The existing PCBA calibration fixture generally does not take any protective measures, making it easy for the detection of key calibration parts to shift, resulting in misjudgment of product calibration failure. In view of this technical status quo, referring to Figures 1 - 5 , an embodiment of the present application provides a calibration device, which includes: a calibration device body and a calibration device protective cover.

[0058] The calibration device body includes: a calibration test board 4, a calibration fixture 8, and a calibration test board baffle 3.

[0059] The calibration test board 4 is used to provide interfaces for the adjustable optical module PCBA to be calibrated, including calibration, communication, measurement (obtaining measurement data through data conversion), and power supply. The calibration test board 4 used in calibration is an important part of the calibration system, mainly including: power circuit, communication circuit, control circuit, switch switching circuit, etc. The power circuit supplies power to the entire calibration test board 4, and the PCBA to be calibrated is connected to the calibration test board 4 through the module electrical interface for calibration; all the indicators to be calibrated are connected to the module electrical interface, such as: FM, BM, PH, MZ, GAIN, SOA, BIAS_P, BIAS_N, etc., and the calibration sequence of these indicators is controlled through the switch switching circuit; the switch switching circuit is connected to the measurement interface, and is connected to the high-precision test source meter through the measurement interface to read the current or voltage feedback value of the indicator; one end of the control circuit is connected to the switch switching circuit, and the other end is connected to the communication circuit, and is connected to the computer through the USB interface, and the operation of the entire calibration program and method is controlled through the computer program.

[0060] The calibration fixture 8 is used to clamp and position the adjustable optical module PCBA to be calibrated for assisting calibration. The front end of the calibration fixture 8 ( Figure 1 the end where the front baffle 1 is located in the middle) has protruding calibration probes, and the calibration probes are very important and easily affected calibration components.

[0061] The calibration test board baffle 3 is arranged between the calibration fixture 8 and the calibration test board 4, and is used to fix the calibration test board 4, so that the calibration fixture 8 and the calibration test board 4 are integrated, thereby facilitating production turnover, customized management, and subsequent daily maintenance.

[0062] In view of the fact that existing PCBA calibration fixtures generally do not have any protective measures, making it easy for the detection of key calibration parts to shift, resulting in misjudgment of product calibration failure. An embodiment of the present application specifically sets up this calibration device protective cover, which can cover the calibration device body and provide protection functions including anti-static for the calibration device body. The shape of the calibration device protective cover is not limited, and it can be a box-shaped cuboid structure such as Figure 4 and Figure 5 Of course, it can also be a cylindrical structure, as long as it can cover the calibration device body and provide anti-static protection functions.

[0063] In the present application, the calibration fixture and the calibration test board are integrated through the calibration test board baffle, thereby facilitating production turnover. By covering the calibration device body with the calibration device protective cover, technical effects such as anti-static, anti-fooling, improving product yield and production efficiency can be achieved, and the probability of detection shift of key calibration parts and misjudgment of product calibration failure is reduced as much as possible.

[0064] For ease of manufacturing, in one embodiment, preferably, the calibration device protection cover is composed of five baffles having an overall plate-like structure, namely, a front baffle 1 , a left baffle 2 , a rear baffle 5 , a right baffle 7 and an upper baffle 6 .

[0065] The front baffle 1 is used to shield the front of the calibration fixture 8. In view of the fact that the calibration fixture 8 has a protruding calibration probe at the front end, and the calibration probe is a very important and easily affected calibration component, in one embodiment, preferably, a part of the front baffle 1 is designed to be convex, forming a front baffle protrusion 101, referring to Figure 3 The front baffle protrusion 101 can wrap around the protruding calibration probe to protect the calibration probe, thereby protecting important components while also taking into account the requirements of product miniaturization and lightweight.

[0066] In one embodiment, further preferably, in order to facilitate the operator to observe the stroke of the calibration probe, a front baffle opening 102 is dug out on the front baffle protrusion 101, for example, a plurality of (for example: 3) circular holes are dug out, so that the operator can observe the complete stroke of the calibration probe, so that the operator can better observe and grasp the calibration progress.

[0067] The left baffle plate 2 is used to cover the left side of the calibration fixture 8, and can be made into a complete plate-shaped surface. In one embodiment, preferably, a left baffle plate opening 201 is set on the left baffle plate 2, referring to Figure 3 , a position is reserved for the installation of a power indicator light, so that the operator can easily observe whether the calibration device is powered on or not.

[0068] The rear baffle 5 is used to cover the rear side of the calibration fixture 8 and the calibration test board 4, and can be made into a complete plate-shaped surface. In one embodiment, in order to reserve a position for the calibration test line to pass through, preferably, a rear baffle opening 501 is provided on the rear baffle 5. The setting of the rear baffle opening 501 facilitates the passage of the calibration test line and facilitates the operator to grasp the corresponding calibration process progress.

[0069] The upper baffle 6 is used to cover the upper part of the calibration fixture 8, and can be made into a complete plate-shaped surface for complete coverage. However, in this case, the operation of the calibration fixture handle (a cylindrical component placed horizontally at the upper end of the calibration fixture 8) is inconvenient, and the upper baffle 6 needs to be opened frequently to operate the calibration fixture handle. In view of this, in one embodiment, preferably, in order to reserve an operating space for the calibration fixture handle, an upper baffle opening 601 is provided on the upper baffle 6, so that the calibration fixture 8 is protected from static electricity while taking into account the convenience of operating the calibration fixture handle.

[0070] The right baffle 7 is used to cover the right side portion of the calibration fixture 8, and can be made into a complete plate-shaped surface for complete coverage.

[0071] In one embodiment, preferably, the machining material of the calibration device protective cover is made of anti-static bakelite. This material has a low cost, good anti-static effect, and high cost performance.

[0072] Another embodiment of the present application provides a baffle, including: first to fourth baffles circumferentially arranged around the calibration device body of any one of the foregoing calibration devices, and a fifth baffle covering the end of the calibration device body. Preferably, the material of the baffle is anti-static bakelite.

[0073] The first baffle, referring to the front baffle 1 of the foregoing embodiment, includes a convex portion in a locally convex shape (referring to the front baffle convex 101 of the foregoing embodiment). The convex portion can wrap the calibration probe protruding on the calibration fixture of the calibration device body therein to provide a protection function. An observation hole (referring to the front baffle opening 102 of the foregoing embodiment) for facilitating the observation of the stroke of the calibration probe is provided on the convex portion.

[0074] The second baffle is provided with a hole for reserving the position of the power indicator light to facilitate observing whether the calibration device is powered on. Refer to the left baffle 2 of the foregoing embodiment.

[0075] The third baffle is provided with a hole for reserving the position for the calibration test line to pass through. Refer to the rear baffle 5 of the foregoing embodiment.

[0076] The fourth baffle is used to block the corresponding side of the calibration fixture 8. Refer to the right baffle 7 of the foregoing embodiment.

[0077] The fifth baffle is provided with a hole for reserving the operation space of the calibration fixture handle. Refer to the upper baffle 6 of the foregoing embodiment.

[0078] Through the anti-static effect of a baffle that can cover the calibration device body, the present application can achieve the technical effects of anti-static, anti-fooling, improving product yield and production efficiency, and reducing the probability of detection displacement of key calibration parts and misjudgment of product calibration failure as much as possible. The overall baffle of this embodiment can refer to the technical description of the calibration device protective cover part in the foregoing calibration device embodiment, and will not be elaborated here.

[0079] Installation steps of the calibration device:

[0080] Step 1. Installation of the front baffle 1: It is installed directly in front of the calibration fixture 8 to block the front part of the calibration fixture 8. More importantly, it first protects the calibration probe of the calibration fixture 8. Considering the miniaturization of the calibration fixture 8, the front baffle 1 is made in a forward convex shape to wrap the protruding calibration probe. At the same time, in order to facilitate the operator to observe the stroke of the probe, three round holes are dug in the forward convex part for the operator to observe the complete stroke.

[0081] Step 2, Installation of the calibration test board baffle 3: It is installed between the calibration fixture 8 and the calibration test board 4, used to fix the calibration test board 4, integrating the calibration test board 4 and the calibration fixture 8, so as to facilitate production turnover, customized management and subsequent daily maintenance.

[0082] Step 3, Installation of the calibration test board 4: It is installed behind the calibration test board baffle 3, used to supply power to the PCBA and conduct calibration tests, connect to the computer control terminal, perform IIC conversion, data conversion, etc.

[0083] Step 4, Installation of the left baffle 2: It is installed on the left side of the calibration fixture 8, with an opening reserved for the power indicator position to facilitate the operator to observe whether the calibration device is powered on.

[0084] Step 5, Installation of the rear baffle 5: It is installed on the rear side of the calibration fixture 8, used to block the rear part of the calibration fixture 8 and the calibration test board 4, and reserve holes for the calibration test lines.

[0085] Step 6, Installation of the right baffle 7: It is installed on the right side of the calibration fixture 8, used to block the right side of the calibration fixture 8.

[0086] Step 7, Installation of the upper baffle 6: It is installed above the calibration fixture 8, to reserve the operating space for the calibration fixture handle, and an upper baffle opening 601 is provided on the upper baffle 6.

[0087] Complete the installation of the calibration device according to the above steps. The materials of all baffles are made of anti-static bakelite, which can not only play the role of anti-static for wrapping the calibration test board and the PCBA to be calibrated, but also consider minimizing the weight of the fixture for the purpose of facilitating turnover. The production process using the calibration device including the baffles can produce products with highly consistent heights, and the frequency of tooling maintenance can be greatly reduced.
