[0030] The clamping mechanism 11 includes a pushing part 132, a clamping plate 110 driven by a cylinder to move forward and backward, and two clamping pieces 112 slidably matched on the clamping plate 110. The clamping plate 110 is provided with a slideway 111, and the clamping piece 112 is provided with a slider 113 adapted to the slideway 111. The slider 113 and the clamping piece 112 are arranged in an integral structure. The pushing part 132 includes baffles 133 located at both ends of the workbench 13 and a push plate 134 located on the base 10. The push plate 134 is controlled by a cylinder to move forward and backward. A push rod 135 is provided on the push plate 134. A through hole 136 is provided on the baffle 133. The push rod 135 is inserted into the through hole 136 for sliding fit. The push rod 135 is arranged in an L shape. A cross block 137 is provided between the push rod 135 and the push plate 134. The push rod 135 and the push plate 134 are fixed to both ends of the cross block 137 by bolts. The workbench 13 is also provided with two through holes 131, and the through holes 131 are located on both sides of the notch 130. The base 10 is also provided with a limiting portion 15, and the limiting portion 15 includes a limiting shaft 150 driven by a cylinder to move up and down, and the limiting shaft 150 is connected to the output shaft on the cylinder, and the limiting shaft 150 is passed through the through hole 131.

[0031] During operation, the bridge wire forming mechanism 1 first operates on the semi-finished bridge wire, places the semi-finished bridge wire on the workbench 13, and the middle position of the semi-finished bridge wire is located at the notch 130. The positioning frame 120 on the positioning device 12 is driven by the cylinder to move toward the workbench 13, driving the positioning plate 121 to move to one side of the semi-finished bridge wire on the workbench 13, and the groove 123 on the positioning plate 121 corresponds to the position of the notch 130 on the workbench 13. The clamping plate 110 on the clamping mechanism 11 is driven by the cylinder to move toward the workbench 13, and the clip 112 is transported to the workbench 13. The clip 112 fixes the other side of the semi-finished bridge wire, and then the top plate 140 on the lifting part 14 is driven by the cylinder to move toward the top of the workbench 13, and the top block 141 is lifted toward the top of the notch 130 by the force of the top plate 140, and the middle part of the semi-finished bridge wire located at the notch 130 is arched, and the arched part is shaped by the groove 123 on the positioning plate 121. At this time, the cylinder on the pushing part 132 drives the pushing plate to move, and the pushing plate drives the push rod 135 to move toward the through hole 136. The end of the push rod 135 contacts the clip 112, and the push rod 135 applies force to push the clip 112 to move toward the middle part of the bridge wire. The clip 112 cooperates with the slide groove on the clamping plate 110 through the slider 113 to achieve movement. When the semi-finished bridge wire is lifted by the lifting block 141, the positions of the two ends of the bridge wire will move, and the clip 112 plays a role in assisting the end of the bridge wire to move toward the middle position, so that the quality of the finished bridge wire is higher. After the finished bridge wire is formed, it is transported to the next workstation by the robot grasping mechanism 2. Before the grasping clamp 20 is clamped, the limit shaft 150 on the limit part 15 is driven by the cylinder to move toward the opening 136 of the workbench 13, and the end of the limit shaft 150 conflicts with the lower end surface of the finished bridge wire. A limit plate 151 driven by the cylinder is arranged above the workbench 13. After the limit plate 151 descends, it contacts with the upper end surface of the finished bridge wire, which stabilizes the finished bridge wire. When clamping, the robot prevents the bridge wire from shifting and affecting the next process of the equipment.

Both the inner pressing block 331 and the outer pressing block 311 are provided with positioning grooves 312, and the opening of the positioning groove 312 is provided with a guide inclined surface 313. The positioning assembly also includes a positioning part 34, which includes a lifting plate 35 driven by a cylinder to move back and forth toward the assembly area 30 and a connecting plate 340 located on the lifting plate 35, the connecting plate 340 is provided with a positioning column 341, the positioning column 341 is movably fitted through the connecting plate 340, the end of the positioning column 341 is provided with a positioning end 342 made of rubber, the positioning column 341 is sleeved with a spring 343, one end of the spring 343 is in conflict with the connecting plate 340, and the other end is in conflict with the positioning end 342. The toggle assembly 36 includes a transverse movable part 360, a longitudinal movable part 361 and a crossbeam 362, and the crossbeam 362 is provided with two toggle rods 363.

[0033] While the bridge wire forming mechanism 1 is working, the assembly mechanism 3 is also working at the same time. The PCB board 6 to be connected on the LCD is located on the assembly area 30. The overall assembly mechanism 3 is controlled by a servo motor so that the lifting frame 32 moves toward the assembly area 30. The inner pressing portion 33 moves toward the assembly area 30 along with the movement of the lifting frame 32, so that the inner pressing block contacts the side of the assembly area 30, and the positioning groove 312 of the inner pressing block 331 clamps the assembly area 30 and the other side of the PCB board 6 inside. The horizontal plate 330 on the outer pressing portion 31 is driven by a cylinder to move toward the side of the assembly area 30, so that the outer pressing block 311 contacts the side of the assembly area 30, and the positioning groove 312 on the outer pressing block 311 clamps the side of the assembly area 30 and the PCB board 6 inside. At this time, the positions of both sides of the PCB board 6 are fixed, and the lifting plate 35 is driven by the cylinder to move toward the assembly area 30, driving the positioning column 341 to contact the PCB board 6 on the assembly area 30, playing the role of contacting and positioning the upper end surface of the PCB board 6. The positioning column 341 is sleeved with a structure composed of a spring 343 and a positioning end 342 made of rubber material, so that the positioning column 341 will not cause damage to the PCB board 6 when it contacts the surface of the PCB board 6. There is a piano cover 4 on both PCB boards 6 that need to be connected. The piano cover 4 includes two strip blocks and a cover sheet sliding between the two strip blocks, and a clamping groove is formed between the cover sheet and the panel of the PCB board 6. A CCD detection device 7 is also provided on the assembly device. The camera on the CCD detection device 7 takes a picture of the position of the PCB board, determines the position of the piano cover 4 on the PCB board 6, and the midpoint position on the PCB board 6 between the two piano covers 4, and transmits the information to the PLC controller at the main control end. The PLC controller controls the manipulator grasping mechanism 2 to adjust the position of the bridge wire based on the information, so that the midpoint position on the bridge wire is aligned with the midpoint position on the PCB board 6.

[0034] The manipulator grasping mechanism 2 inserts the two ends of the bridge wire between the two strip blocks, and the longitudinal movable part 361 on the toggle assembly 36 is driven by the cylinder to drive the movable block 365 to move, and the movable block 365 drives the cover plate 364 to slide, which plays the role of moving the crossbeam 362 toward the assembly area 30, so that the lever 363 moves to the cover plate of the piano cover 4, and then through the movement of the transverse movable part 360, the crossbeam 362 is driven to move forward, and the lever 363 will push the cover plate to move toward the bridge wire direction, which plays the role of clamping the two ends of the bridge wire between the cover plate and the PCB board 6, so that the bridge wire connects the two PCB boards 6. This production method realizes the automatic molding of the bridge wire and the automatic assembly of the bridge wire and the PCB board 6, with high work efficiency, saving manual labor, and at the same time improving the product yield rate, which is conducive to improving the work quality of the product.
