In order to avoid the pin end 52 from being bent and formed in a non-proper position, the supporting block 345 can be used to adjust the bending radian position and the limiting leg, so that when the pin end 52 is too long, the bending deformation is prevented from being formed in a non-proper position (i.e. the supporting block 345 and the adjusting rod 344 are adjusted to be matched with each other, the adjusting rod 344 is adjusted upwards or downwards to determine the bending position, and the adjusting piece is adjusted to ensure the whole height of the device). Stopper 339 is fixed in spacing seat 341, and stopper 339 and pin lower locating piece 337 contact each other, and stop screw 336 and spacing seat 341 are connected, through adjusting stop screw 336, can realize prescribing a limit to the position of location cutter 331.

It should be noted that, the fixed block 222 is driven to move forward along the slide rail 227 (i.e. move toward the right side in fig. 2) by the extension of the push rod of the air cylinder 212 in the driving mechanism, and the first push block 224 and the second push block 226 are driven to move forward together, so as to push the base 311 of the mounting component in the driven mechanism, and the cutter 331 and the limiting component in the driven mechanism move forward, the cutter 331 cuts the pin end of the optical module assembly passing through the cutting hole 3111, and due to the movement of the cutter 331 and the pressing block 321 and the pin adjusting component 322 of the limiting component in the driven mechanism, the pin end 52 is bent while the pin end 52 is cut, so as to achieve the cutting and bending of the pin end 52. Before the pin end 52 is cut, bent and formed, the adjustment screw 319 may be adjusted, for example, the extension length of the adjustment screw 319 is adjusted, so that the curvature of the bent pin end 52 is smaller, or the curvature of the bent pin end 52 is larger, so as to adjust the curvature of the bent pin end 52, and the depth of the pin adjustment block and the height of the adjustment rod 344 are adjusted, so as to determine the overall height and the bending position of the device, and then the pin end 52 is cut, bent and formed after being adjusted. When the pin terminals 52 of different types of OSA optical module devices need to be cut, the OSA optical module devices mainly comprise a TOSA, a ROSA and a BOSA, and the difference between the TOSA and the ROSA is mainly that the overall height after bending and cutting is different from the diameter of the tube body, so that the device with different sizes and specifications can be met by designing the diameter and the depth of the inner groove (i.e. the space for placing the optical port end) of the pin adjusting piece 322 matched with the pressing block 321 to be matched and debugged, and the pin terminals 52 of the different types of OSA optical module devices can be cut. For BOSA, the shape of the inner groove in the pin adjuster 322 may be changed from a round groove to a square groove, and other adjusting manners may be unchanged. In order to prevent the tube legs (i.e., the cut portions of the pin ends 52) from splashing and being unrecoverable due to the cut pin ends 52 (i.e., the pins), the curved cutting pin fixture applied to the optical module assembly provided by the embodiment of the invention further comprises a storage box 4, wherein the storage box 4 is detachably connected with the base 1, and the cutting member is positioned between the storage box 4 and the base 1. That is, by placing the storage box 4 in the bottom of the stopper seat 341 (that is, by providing a space for accommodating the storage box 4 in the stopper seat 341, the open surface of the storage box 4 faces the pin end 52, so that the cut pin end 52 falls into the storage box 4), the tube legs are not splashed by restricting the periphery of the storage box 4, and the tube legs can be recovered. As shown in fig. 5, the storage box 4 has a small volume, does not occupy the operating table, and can achieve the pin splashing fool-proof effect.

With continued reference to fig. 8 (marked a in fig. 8 is a dimension a, B is a dimension B, and E is an dimension E) and fig. 10 (marked C in fig. 10 is a dimension C), in a specific operation, first, the determination method for the dimension a (i.e., the total height of the device after bending cutting) and the dimension B (i.e., the measured height of the device) may be the theoretical length, and the dimensions a and B of the OSA device may be determined according to the manufacturer's drawing. The actual length can be determined according to the a size and the B size determined by actual measurement, and when the a size and the B size are set by the actual pin adjusting element 322, the actual length needs to be determined, and the theoretical length is only used as a reference before adjustment. Secondly, the E size is a fixed value of the tool and is constant all the time, and the measured value of the tool is 6.5 mm. Then, the D size was confirmed by: the empirical formula is currently determined by summarizing the initial values as D ═ a-B-1-0.8-solder length (1.2)) ÷ 2+1+0.8, but while ensuring that the solder land length of the PCB is 2.4mm, in order to ensure good contact of the device pins on the PCB, it is recommended that the D dimension range from 2.65mm to 3.8mm, according to practical experience. Since the upper limit of the dimension D is 5.3mm, it is actually necessary to be less than 5.2mm to ensure the safety of the jig, and it should be noted that the distance from the end face of the device insulator to the orifice plate is equal to a-B-D, and the larger the dimension value, the more labor-saving the pressing of the pressing block 321 is, and the recommended value is more than 2 mm. Then, the C size (the amount of reshaping) is determined by theoretically determining the center vertical distance between the device and the PCB when they are mounted on the base 311, and this calculated value can be used as a reference for the initial setting, and the C size of the currently commonly used device is set to be in the range of 1.5mm to 1.7 mm. The actual shaping amount C is determined based on the effect of the bending and cutting, and can be adjusted by increasing or decreasing a spacer of 0.1mm or 0.2 mm. Finally, in actual operation, the device is inserted into the orifice plate without being pressed, and is required to be normally placed in the orifice plate and pressed by the pressing block 321.
