Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0025] Please refer to Figures 1 to 4 The utility model provides a technical scheme: multi-channel intensity modulator photoelectric test tool, including control machine box body 1, the front of control machine box body 1 is installed with test assembly 200, the front of control machine box body 1 is installed with placing assembly 300, through the cooperation between test assembly 200 and placing assembly 300 of the outside of control machine box body 1, can conveniently distinguish and place test workpiece, so that the test workpiece in each area can be separated, also can utilize longitudinal space simultaneously, prevent the article placed on the table top to be more, influence the placement of other tools, thereby facilitating the test work of staff, improve the convenience of test process, thereby effectively improve the practicability of multi-channel intensity modulator photoelectric test tool.
[0026] The placing assembly 300 in the embodiment is a structure for facilitating test workpiece placement.
[0027] As Figure 1 , Figure 2And Figure 3 As shown in FIG. 1, the placing assembly 300 comprises eight fixed cylinders 301 fixed on the front of the control cabinet body 1, adjusting rods 302 slidingly connected to the inner side of the fixed cylinders 301, placing plates 303 fixed between the front ends of the corresponding two adjusting rods 302, limiting frames 304 fixed on the front of the placing plates 303, anti-skid pads 305 adhered to the front of the placing plates 303 and located inside the limiting frames 304, threaded rods 306 threaded through and connected to the outer side of the fixed cylinders 301, fixed blocks 307 fixed on the side of the threaded rods 306 away from the corresponding fixed cylinders 301, and handles 308 fixed on the side of the fixed blocks 307 away from the corresponding fixed cylinders 301.
[0028] It should be noted that the front of the fixed cylinder 301 is provided with an opening, and the corresponding two fixed cylinders 301 are symmetrically distributed left and right, so that the adjusting rod 302 can normally slide inside the corresponding fixed cylinder 301, and the corresponding two placing plates 303 are symmetrically distributed up and down, so that the positions of the placing plates 303 can be staggered, so that the space on the front of the control cabinet body 1 is not excessively blocked, and at the same time, when not working, the placing plates 303 can be moved to the position closest to the front of the control cabinet body 1, facilitating the storage and placement of the whole test tool.
[0029] In addition, the end of the threaded rod 306 abuts against the outer side of the corresponding adjusting rod 302, at this time, the fixed block 307 abuts against the outer side of the corresponding fixed cylinder 301, so that the threaded rod 306 can abut and limit the outer side of the adjusting rod 302, and the end of the threaded rod 306 and the outer side of the adjusting rod 302 are both rough surfaces, which can improve the friction and facilitate stable abutting and limiting, and the two handles 308 on the back of the same placing plate 303 are symmetrically distributed left and right, the handle 308 is in a strip shape, and the outer side is in an arc shape, facilitating the staff to hold and rotate.
[0030] The test assembly 200 in this embodiment is a structure for providing a plurality of test channels for testing workpieces.
[0031] As shown in FIG. 1, Figure 1 And Figure 2 As shown in FIG. 1, the test assembly 200 comprises a plurality of intensity modulator bias control boards 201 integrally installed on the front of the control cabinet body 1, a plurality of laser driver control boards 202 integrally installed on the front of the control cabinet body 1, a plurality of external laser bodies 203 integrally installed on the front of the control cabinet body 1, a plurality of terminal post bodies 204 integrally installed on the top of the control cabinet body 1, and a terminal panel 205 integrally installed on the bottom of the control cabinet body 1.
[0032] It should be noted that the main control circuit board is integrated inside the control chassis 1, which can play the role of overall signal transmission and delivery. The photoelectric detector is integrated inside the wiring panel 205, which facilitates testing after connecting to the test workpiece through cables.
[0033] In addition, an intensity modulator bias control board body 201, a laser driver control board body 202, and an externally modulated laser body 203 can form a test group. The number of test groups is eight, so that the eight test groups installed on the front of the same control chassis body 1 can simultaneously test multiple test workpieces. The working principles of the above test elements are all existing publicly available technologies, so they will not be described in detail.
[0034] The working principle of the above embodiments is as follows:
[0035] When testing the workpiece, rotating the handle 308 causes the fixed block 307 to rotate the threaded rod 306. This, in turn, causes the threaded rod 306 to move away from the corresponding adjusting rod 302 due to the external threaded connection, thus removing the limiting contact of the threaded rod 306. This moves the placement plate 303 to a height convenient for the operator to place and hold. Rotating the handle 308 in the opposite direction locks the height of the placement plate 303 through the limiting contact between the threaded rod 306 and the adjusting rod 302. The workpiece to be tested is then placed on top of the anti-slip mat 305. Connecting cables to the intensity modulator bias control board 201, the laser driver control board 202, the externally modulated laser 203, and the wiring panel 205 facilitates various testing tasks without occupying horizontal space on the table, ensuring efficient testing.
[0036] Compared with existing technologies, this multi-channel intensity modulator photoelectric testing fixture, through the coordinated use of the testing component 200 and the placement component 300 on the outside of the control chassis 1, can facilitate the differentiation and placement of test workpieces, allowing test workpieces in different areas to be separated. At the same time, it can utilize the vertical space to prevent the placement of too many objects on the table from affecting the placement of other tools, thereby facilitating the testing work of the staff and improving the convenience of the testing process. This effectively enhances the practicality of the multi-channel intensity modulator photoelectric testing fixture and solves the problem that existing multi-channel intensity modulator photoelectric testing fixtures tend to place too many test workpieces at once, occupying a large amount of table space during actual use.
[0037] All electrical components mentioned in this article are electrically connected to the main controller and power supply. The provision of power supply is common knowledge in the field. The main controller can be a conventional known device that controls computers, etc. It can be implemented by a person skilled in the art through simple programming. All of these are existing publicly available power connection technologies, which will not be described in detail in this article.
[0038] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
