The pair of driving wheels 332 can drive the ribbon 390 to move along the first direction D1. The driving wheels 332 can sequentially convey the electrical components to a bending position, at which the ribbon body of the ribbon 390 is located in the limiting gap, and the component body is located outside the operation plane. The positioning member 342 can move along a second direction D2 and abut against the component body of each electrical component when the electrical component moves to the bending position, so that the component body is kept in a preset position after moving relative to the operation table 322 to achieve positioning. Thus, the distance from each component body of the electrical component reaching the bending position to the edge of the operation plane is equal. The bending member 352 is movably arranged on the first frame 310 along a third direction D3 and the opposite direction thereof perpendicular to the operation plane. The bending member 352 can abut against the pin 398 of the electrical component abutted by the positioning member 342 outside the operation plane along the third direction D3 and bend the pin 398 at the edge of the operation plane. The photoelectric component assembling substation can keep each electrical component in a preset position by the positioning member 342 before bending each electrical component, and can bend the pin 398 of the electrical component by the bending member 352 abutting against the operation plane, so that the bending positions of the pins 398 of each electrical component are equal, and the processing precision of the electrical component is improved.

[0117] Figure 4 Another state of the photoelectric component assembling substation is partially shown. Referring to Figure 3 and Figure 4 The photoelectric component assembling substation further comprises a clamping member 362 and a resilient member 364. The clamping member 362 is movably arranged on the bending member 352 along the third direction D3 and the opposite direction thereof. The resilient member 364 is a compression spring arranged along the third direction D3, and abuts against the bending member 352 and the clamping member 362 respectively. The resilient member 364 can drive the clamping member 362 to abut against the operation plane with the pin 398 of the electrical component during the process that the bending member 352 abuts against and bends the pin 398 of the electrical component. Thus, the position of the pin 398 during the bending process is further fixed, and the processing precision is improved.

[0118] Figure 5 This is a schematic diagram illustrating one possible implementation of a welding substation. Figure 6 for Figure 5 The diagram shows a partial structural schematic of the welding substation. (Refer to...) Figure 5 and Figure 6 The welding substation 400 includes a second frame 410, a turntable 420, two fixing mechanisms 430, and a second joint 440. The turntable 420 is rotatably connected to the second frame 410 about a rotation axis (as shown by the dotted line in the diagram). A fourth direction D4 is parallel to the rotation axis of the turntable 420. The two fixing mechanisms 430 are disposed on the turntable 420 and are evenly distributed about the rotation axis of the turntable 420. Each fixing mechanism 430 includes a fixing unit 431 and a first joint 432. Each fixing unit 431 includes a pair of clamping cylinders 4311, which can move relative to or away from each other along a direction perpendicular to the fourth direction D4. The clamping arms 4311 are used to clamp or release semi-finished products during the production process. The fixing units 431 of each fixing mechanism 430 can rotate with the turntable 420 to a loading / unloading station and a welding station of the welding substation, respectively. Figure 5 In the diagram, the lower left fixing unit 431 is located at the loading / unloading station, and the upper right fixing unit 431 is located at the welding station. Since the two fixing mechanisms 430 are evenly distributed around the rotation axis of the turntable 420, the two fixing units 431 interchange positions after the turntable 420 rotates 180 degrees. The second connector 440 can move relative to the turntable 420 in a direction parallel to the fourth direction D4 under the drive of a cylinder, to connect and disconnect from the first connector 432 corresponding to the fixing unit 431 that has moved to the loading / unloading station. This illustrative embodiment of the welding substation allows for convenient and efficient loading and unloading of components while welding. The detachable connection between the first connector 432 and the second connector 440 prevents the energy pipe / wire connected to the second connector 440 from becoming entangled in the second frame 410 as the turntable 420 rotates, thereby improving stability during use.

[0119] In the illustrative embodiment, the turntable 420 has two clearance openings 421 extending along the fourth direction D4. Each clearance opening 421 corresponds to a pair of clamping cylinders 4311 in the fourth direction D4, allowing the workpiece to pass through the clearance opening 421 along the fourth direction D4 and reach between the pair of clamping cylinders 4311. This allows semi-finished products to be loaded and unloaded from the clearance openings 421 in a direction parallel to the fourth direction D4. This structure helps save space.

[0120] Figure 7 This is a schematic diagram illustrating one possible implementation of a calibration substation. Figure 8 for Figure 7 The exploded view of a partial calibration station is shown. (Refer to...) Figure 7 andFigure 8 The calibration station comprises a fixed frame 510, a moving frame 520, an adapting unit 530, a sample fixing member 540, a positioning assembly 550, a pressing assembly 560, a loading turntable 570, and a plurality of clamps 580. The loading turntable 570 is rotatably arranged on the fixed frame 510. The plurality of clamps 580 are distributed around the rotation axis of the loading turntable 570 and are used for the semi-finished product in the production process. Each clamp 580 can be rotated to a calibration station of the calibration station. The moving frame 520 is movably connected to the fixed frame 510 along a fifth direction D5 and the opposite direction thereof, which is parallel to the rotation axis of the loading turntable 570. The adapting unit 530 comprises an adapting frame 531, a driving member 532, an elastic member, and a driving cylinder 534. The adapting frame 531 is movably connected to the moving frame 520 along a sixth direction D6 and the opposite direction thereof, which is perpendicular to the fifth direction D5, and is limited to move between a first position and a second position. The adapting frame 531 is movably connected to the moving frame 520, for example, through a slide rail structure, but is not limited thereto. The body of the driving cylinder 534 is fixedly connected to the moving frame 520, and the output end thereof is fixedly connected to the driving member 532 to drive the driving member 532 to move along the sixth direction D6 and the opposite direction thereof. The elastic member 33 applies force to the adapting frame 531 and the driving member 532. The driving member 532 can drive the adapting frame 531 to move from the first position to the second position along the sixth direction D6 through the elastic member. The sample fixing member 540 is connected to the adapting frame 531 and is used for fixedly connecting the optical sample. As shown in Figure 8 , the sample fixing member 540 comprises a rotating member 541 and two second bolts 543. The rotating member 541 is rotatably connected to the adapting frame 531 around an axis parallel to the fifth direction D5 and is used for fixedly connecting the optical sample. The two second bolts 543 are threadedly connected to the adapting frame 531 and define the relative rotation position of the rotating member 541 and the adapting frame 531 by abutting against the rotating member 541. The two second bolts 543 can adjust the relative rotation position of the rotating member 541 and the adapting frame 531 by moving relative to the adapting frame 531. The calibration station can adaptively adjust the position of the optical sample fixed to the sample fixing member 540 according to the actual position of the optical assembly of the semi-finished product, so that the optical sample can always abut against the optical assembly of the semi-finished product when calibrating different models of semi-finished products. In this way, the requirement of high-precision calibration is met.
