Abstract
Description
Technical Field
[0001] The utility model relates to the field of optical communication, in particular to an adjustable-focus chip mounting jig applied in the manufacturing process of optical device packaging. Background Art
[0002] For many domestic chip eutectic devices, their CCDs cannot automatically focus and can only adjust the focal length through programs, which poses great difficulties for chip recognition. After the program of the mounting device is adjusted, the requirements for the consistency of the heights of the G-PACK box and the chip are very high. In actual production, on the one hand, it is difficult to meet this condition. Chips need to be poured into G-PACK boxes with a fixed height, and this process is likely to scratch the chips. On the other hand, even if the condition of height consistency is met, the production cost will increase significantly. Summary of the Utility Model
[0003] To solve the above problems, the utility model provides an adjustable-focus chip mounting jig: a special jig for placing the G-PACK box is installed on an adjustable-focus sliding table. When the CCD of the chip eutectic device cannot clearly identify the chip, manually rotate the rotating rod of the sliding table until the image on the CCD display is the clearest.
[0004] The technical solution adopted by the utility model to achieve the above purpose is: an adjustable-focus chip mounting jig, which is characterized by comprising a fixed sliding table, an adjustable sliding table and a jig for placing the G-PACK box that are detachably connected. A fixed sliding table threaded hole is opened on one side of the fixed sliding table. The jig for placing the G-PACK box includes a placing table and a connecting handle. A positioning groove for placing the G-PACK box is opened on the placing table. A threaded hole of the jig for placing the G-PACK box is opened on the connecting handle. The adjustable sliding table includes an adjustable sliding table screw rod, a fixed block, a movable block and a crossed roller guide rail. An adjustable sliding table threaded hole one for connecting the fixed sliding table is opened on the outside of the fixed block, and the movable block is connected to the fixed block through the crossed roller guide rail on the inside. The movable block is connected to the adjustable sliding table screw rod, and an adjustable sliding table threaded hole two for connecting the jig for placing the G-PACK box is opened on the outside of the movable block.
[0005] The fixed sliding table threaded hole and the adjustable sliding table threaded hole one are connected by a bolt one, and the threaded hole of the jig for placing the G-PACK box and the adjustable sliding table threaded hole two are connected by a bolt two.
[0006] The material of the jig for placing the G-PACK box is aluminum alloy.
[0007] Compared with the prior art, the utility model has the following advantages:
[0008] The focal length can be adjusted at any time without changing the program, making the image recognition clearer, reducing the operation difficulty and improving the accuracy of chip eutectic.
[0009] The requirement for the consistency of the height of the G-PACK box is reduced, and the chip does not need to be inverted, saving labor cost.
[0010] The chip does not need to be inverted in the G-PACK box, solving the problem of chip scratching. Brief Description of the Drawings

Detailed Description of the Invention
[0017] The following will combine the drawings and specific embodiments to illustrate the specific implementation manners of the present invention. Embodiment
[0018] As Figures 1-3 shown, an adjustable focus chip mounting jig includes a detachably connected fixed sliding table 1, an adjustable sliding table 6 and a placing G-PACK box jig 9. A fixed sliding table threaded hole 2 is opened on one side of the fixed sliding table 1. The placing G-PACK box jig 9 includes a placing table 91 and a connecting handle 92. A positioning groove 93 for placing the G-PACK box is opened on the placing table 91. A placing G-PACK box jig threaded hole 8 is opened on the connecting handle 92. The adjustable sliding table 6 includes an adjustable sliding table screw 10, a fixed block 62, a movable block 61, and a crossed roller guide 63. An adjustable sliding table threaded hole one 4 for connecting the fixed sliding table 1 is opened on the outside of the fixed block 62, and the movable block 61 is connected to the inside through the crossed roller guide 63. The movable block 61 is connected to the adjustable sliding table screw 10, and an adjustable sliding table threaded hole two 5 for connecting the placing G-PACK box jig 9 is opened on the outside of the movable block 61.
[0019] The fixed slide table threaded hole 2 and the adjustable slide table first threaded hole 4 are connected by a first bolt 3, and the G-PACK box placing fixture threaded hole 8 and the adjustable slide table second threaded hole 5 are connected by a second bolt 7.
[0020] The material of the G-PACK box placing fixture 9 is aluminum alloy.
[0021] As Figure 4 shown, when the utility model is in use, the fixed slide table threaded hole 2 and the adjustable slide table first threaded hole 4 are connected by a first bolt 3, so as to connect the adjustable slide table 6 and the fixed slide table 1. The G-PACK box placing fixture threaded hole 8 and the adjustable slide table second threaded hole 5 are connected by a second bolt 7, so as to connect the G-PACK box placing fixture 9 and the adjustable slide table 6.
[0022] As Figure 5 shown, when in use, the assembled fixture is installed on the eutectic equipment, the CCD lens 12 is aligned with the position of the positioning groove 93, and the G-PACK box containing the chip is placed on the positioning groove 93. When the picture displayed on the display 11 of the eutectic equipment is not clear, turn the adjustable slide table screw rod 10. When the screw rod is turned, it drives the movable block 61, so that the movable block 61 moves along the linear direction of the crossed roller guide 63, thereby driving the movement of the G-PACK box placing fixture 9. As the relative position between the G-PACK box and the CCD lens 12 changes, the image distance of the chip changes, so that the chip picture can be adjusted to the clearest.
