Further, the light measuring device with good stability further includes a sleeve 60, one end of the sleeve 60 sequentially passes through one of the first assembly holes, the second assembly hole and the other second assembly hole, and the other end is located at the top of the connection block 352, and the light measuring device with good stability further includes a fastener 70, where the fastener 70 penetrates one of the connection portions and is in threaded connection with the sleeve 60, so as to define the position of the sleeve 60.
Wherein it will be appreciated by those skilled in the art that the stability of the sleeve 60 placed on the bracket assembly 30 is ensured by the above-described crossed arrangement of the first and third rotating frames 31 and 33 and the second and fourth rotating frames 32 and 35.
It should be noted that, in use, the positioning of the sleeve 60 is manually controlled, for example, from 6*4 sampling points, so that the sleeve 60 is manually moved to the point of 0, then 0,1, and so on up to the point of 5, 3. As shown in fig. 4, A, B, C are three points, so that two arms AB and BC can be set, a is the first steering engine 40, b is the third steering engine 34, and when the user manually adjusts the position of the sleeve 60, the rotation angle can be returned to the control circuit due to the closed-loop control of the steering engine. Assuming that the rotation angles of the steering engines a and b are θa and θb, respectively, and the lengths of the arm AB and the arm BC are L1 and L2, respectively, we can define a coordinate system as follows: a is located at the origin, the positive direction of the X axis is A to B, and the positive direction of the Y axis is A vertically upwards.
Since the rotation angle θa of the steering engine a determines the direction of the arm AB, the rotation angle θb of the steering engine b determines the direction of the arm BC with respect to AB. Assuming that thetaa and thetab are both measured clockwise from the positive X-axis, the coordinates of point B can be expressed as (L1X cos (thetaa), L1 sin (thetaa)), and the coordinates of point C, we need to consider the relative angles of AB and BC, that is thetaa + thetab. Therefore, the coordinates of C can be expressed as (L1 x cos (θa) +l2 x cos (θa+θb), L1 x sin (θa) +l2 x sin (θa+θb)), so that we can calculate the position of C, that is, the coordinates of the sleeve 60, and thus automatically obtain the actual sampling point coordinates corresponding to the current test point.
In addition, when in use, the device can rapidly switch different sampling point setting conditions, such as 5*3 or 10 x 6, according to the printing areas of different models. Since the coordinates of the point C are recorded during sampling, the compensation gray level map can be calculated according to the brightness of the cells on the acquired matrix after all the acquisition is completed.
In addition, a photoreceptor and a PLC circuit board are further disposed in the cavity 103, and the photoreceptor, the first steering engine 40, the second steering engine and the third steering engine 34 are all connected with the PLC circuit board, where the light measuring device with good stability further includes an optical fiber 80, one end of the optical fiber 80 is matched with the photoreceptor, and the other end is disposed in the sleeve 60, where we use a scheme of fixing the photoreceptor and using the optical fiber 80 to conduct light. Light propagates from the point of incidence to the photoreceptor by total reflection, rather than using a solution that moves the photoreceptor. In this way, on the one hand, the coordinates of the collection point can be obtained, on the other hand, after fixing, the movement of the C point depends on the movement of the bracket assembly 30, so that the vertical height uniformity of the collection point can be ensured, and as will be understood by those skilled in the art, the working principle of the projector is that the attenuation of the light intensity is in a quadratic relation with the distance, so that the influence of the height (projection distance) on the light intensity is very great, and thus, it is particularly critical to ensure the stability in the movement process of the sleeve 60.
In addition, the nixie tubes can display the rotation angle of the steering engine, namely, a user can install three nixie tubes outside the machine body 10, and the three nixie tubes are connected with the PLC circuit board.
In summary, the light measuring device with good stability according to the embodiment of the application is illustrated, which provides advantages of convenient use, convenient positioning, good stability and the like for the light measuring device with good stability.
It is worth mentioning that in the embodiment of the application, the light measuring device with good stability has simple structure, does not involve complex manufacturing process and expensive materials, and has higher economy. Meanwhile, for manufacturers, the photometry equipment with good stability is easy to produce, has low cost, is more beneficial to controlling the production cost, and is further beneficial to product popularization and use.
It will be appreciated by persons skilled in the art that the embodiments of the utility model described above and shown in the drawings are by way of example only and are not limiting. The objects of the present utility model have been fully and effectively achieved.
