Description

Technical Field

[0001] The present invention relates to the technical field of transceiver assembly, in particular to a single-fiber bidirectional transceiver component assembly device. Background Art

[0002] A single-fiber bidirectional transceiver is a fiber optic communication device that can realize bidirectional data transmission on a single optical fiber. A single-fiber bidirectional transceiver is usually composed of a metal shell and a circuit board. During the assembly process of a single-fiber bidirectional transceiver, it is usually necessary to place a circuit board with four matrix-distributed threaded holes (see Figure 8 ) is fixed by screws to an L-shaped metal upper housing with four matrix-distributed threaded holes (see Figure 8 ), and then install the L-shaped metal shell with the circuit board installed on the lower shell to complete the assembly process of the single-fiber bidirectional transceiver.

[0003] At present, the processing of the single-fiber bidirectional transceiver is usually that after the L-shaped metal shell is fixed, the staff holds an electric screwdriver to tighten the screws at the corresponding threaded holes of the circuit board.

[0004] At present, the following problems exist in the processing of single-fiber bidirectional transceivers: 1. In the existing processing of single-fiber bidirectional transceivers, workers are required to place a circuit board on an L-shaped metal shell by holding it, and then use an electric screwdriver to fix multiple screws in the corresponding threaded holes after positioning the threaded holes on the circuit board. The method in which workers position the threaded holes by holding the circuit board easily causes the position of the threaded holes on the circuit board to deviate from the position of the threaded holes on the metal shell, thereby making it impossible for subsequent screws to be correctly installed in the corresponding positions. Secondly, the overall operation steps are cumbersome and the assembly efficiency is low.

[0005] 2. During the installation of screws, workers are usually required to locate the position of the threaded holes on the circuit board while pressing the circuit board against the metal shell. During the installation process, the position of the threaded holes on the circuit board may deviate from the position of the threaded holes on the metal shell due to the downward pressure on the circuit board, which may cause damage to the circuit board during the installation of the screws, shortening the service life of the single-fiber bidirectional transceiver.

[0035] like Figure 1 , Figure 2 and Figure 5 As shown, the positioning mechanism 7 includes a rotating rod 70, and the front section of the sliding plate 6 rotates through the rotating rod 70 with an axis extending from top to bottom. The rotating rod 70 is connected to an external motor 1 (not shown in the figure), and a rotating plate 1 71 is fixedly provided on the lower end surface of the rotating rod 70. Two symmetrically distributed electric screwdrivers 72 are fixedly provided on the lower end surface of the rotating plate 1 71.

The positioning mechanism 7 includes a guide group 75 for guiding the circuit board.

[0036] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the clamping mechanism 4 includes a driving shaft 40, and the upper end surface of the movable plate 3 is rotatably provided with a driving shaft 40 whose axis is colinear with the axis of the rotating rod 70, the driving shaft 40 is connected to an external motor 2 (not shown in the figure), and a clamping group 41 is commonly provided between the driving shaft 40 and the movable plate 3, and four matrix-distributed slide grooves 42 are provided on the bottom plate 1, and vertical bars 48 are slidably provided in the slide grooves 42, and a clamping plate 43 for clamping the horizontal section of the metal shell is fixedly provided on the upper end surface of the vertical bar 48, and a clamping group 2 44 is commonly provided between all the clamping plates 43 and the bottom plate 1, and a placement groove 45 located on the front side of the fixed column 2 is provided through the rear section of the bottom plate 1, and a transmission group 46 is commonly provided between the placement groove 45 and the movable plate 3.

[0037] During operation, the staff places the circuit board under the movable plate 3, and the external motor 2 drives the clamping group 1 41 to complete the clamping of the circuit board. Then the staff places the horizontal section of the L-shaped metal shell between the four clamping plates 1 43 on the bottom plate 1, and then the external hydraulic cylinder 1 drives the movable plate 3 to move downward. During the movement of the movable plate 3, the transmission group 46 is driven to work, and the clamping group 2 44 is driven by the transmission group 46 to drive the four clamping plates 1 43 to complete the centering clamping of the metal shell. The movable plate 3 continues to move downward and performs preliminary positioning of the circuit board and the metal shell through the guide group 75. At the same time, the external hydraulic cylinder 2 works to drive the two positioning rods 74 to move downward synchronously through the rotating plate 2 73, and the two positioning rods 74 pass downward through the corresponding threaded holes on the circuit board, so that each thread on the circuit board After the holes are all in the specified positions, the movable plate 3 drives the circuit board and the two positioning rods 74 to move downward, and the two positioning rods 74 pass through the corresponding threaded holes on the metal shell to complete the positioning of the circuit board and the metal shell, and then the screws are fixed to the corresponding positions on the circuit board and the metal shell by the electric screwdriver 72. Then, the external hydraulic cylinder 2 works to drive the positioning rods 74 and the electric screwdriver 72 to move upward, and then the external motor 1 works to drive the rotating rod 70 to drive the two electric screwdrivers 72 to rotate to the position where the screws are not installed, and then the external hydraulic cylinder 2 works to drive the two electric screwdrivers 72 to move downward and fix the screws to the corresponding positions on the circuit board and the metal shell, and then the external motor 2 works to drive the clamping group 1 41 to loosen the clamping of the circuit board, and the external hydraulic cylinder 1 works to drive the movable plate 3 to move upward and reset.

[0038] like Figure 2 and Figure 3 As shown, the clamping group 41 includes a gear 410, a gear 410 is fixedly sleeved on the driving shaft 40, four sliding bars 411 distributed in a matrix are slidably penetrated on the moving plate 3, each sliding bar 411 is fixedly provided with a rack 412 meshing with the gear 410 through a connecting block, and two adjacent racks 412 are staggered up and down, two sliding blocks 413 are slidingly provided on the moving plate 3, and the two sliding blocks 413 are respectively located on both sides of two sliding bars 411 opposite to each other, a spring 414 is fixedly provided between the sliding block 413 and the corresponding sliding bar 411, and a clamping plate 415 for clamping the circuit board is fixedly provided on the lower end surfaces of the left and right sliding bars 411 and the two sliding blocks 413.

[0039] During operation, the staff holds the circuit board and places it between the four clamping plates 2 415 under the moving plate 3. Then the external motor 2 works to drive the gear 1 410 to rotate through the driving shaft 40. The gear 1 410 is meshed with each rack 1 412 to make each rack 1 412 move toward the driving shaft 40. The two racks 1 412 opposite to each other drive the corresponding clamping plates 2 415 to approach each other through the sliding bar 411. The metal shell is clamped in the left and right directions by the two clamping plates 2 415 opposite to each other. The two racks 412 facing each other at the same time drive the corresponding sliding bars 411 to approach each other, and the sliding bars 411 drive the corresponding sliding blocks 413 to move synchronously through the springs 1 414. The sliding blocks 413 drive the corresponding clamping plates 2 415 to contact the circuit board, and then the clamping plates 2 415 stop moving, so that the springs 1 414 are stretched and deformed. The elastic force generated by the deformation of the two springs 1 414 acts on the circuit board through the corresponding clamping plates 2 415, thereby completing the clamping and limiting of the circuit board through the two clamping plates 2 415 facing each other at the front and back.

[0040] like Figure 2 and Figure 6 As shown, the transmission group 46 includes a second gear 460, and a transmission rod extending from left to right through the axis in the placement groove 45 is rotatably provided with the second gear 460, and a push plate 461 is slidably provided on the lower end surface of the rear section of the base plate 1, and a rack 2 462 meshing with the second gear 460 is fixedly provided on the rear end surface of the push plate 461, and a rack 3 463 meshing with the second gear 460 is fixedly provided on the lower end surface of the movable plate 3, and the rack 1 412 and the rack 2 462 are staggered with each other.

[0041] like Figure 6 As shown, the clamping group 2 44 includes a transmission shaft 440, and the lower end surface of the base plate 1 is rotatably provided with a transmission shaft 440 whose axis extends from top to bottom, and the axis of the transmission shaft 440 is colinear with the axis of the driving shaft 40, and a gear 3 441 is fixedly sleeved on the driving shaft 40, and the lower section of each vertical bar 48 is fixedly provided with a rack 442 meshing with the gear 3 441 through a connecting plate, and two adjacent racks 442 are staggered up and down.

[0042] During operation, after clamping the circuit board, the staff places the horizontal section of the L-shaped metal shell between the four clamping plates 1 43 on the bottom plate 1, and then the external hydraulic cylinder 1 drives the moving plate 3 to move downward, and the moving plate 3 drives the rack 3 463 to move downward synchronously, and the gear 2 460 is rotated by the meshing between the rack 3 463 and the gear 2 460, and the gear 2 460 is meshed with the rack 3 463 to move forward, and the rack 3 463 drives the push plate 461 to move forward synchronously, and the push plate 461 moves to push the rear vertical bar 48 to move forward. The gear three 441 rotates through the meshing between the gear three 441 and each rack four 442, and each rack four 442 moves through the meshing between the gear three 441 and each rack four 442. Each rack four 442 drives the corresponding vertical bar 48 to move toward the direction close to the drive shaft 40, and each vertical bar 48 drives the corresponding clamping plate one 43 to move synchronously to press the four circumferential surfaces of the metal shell, thereby completing the centering clamping of the metal shell, so that the metal shell is in the specified position on the base plate 1.

[0043] like Figure 6 and Figure 7 As shown, a locking group 47 is provided in the rear side slide groove 42, and the locking group 47 includes a locking groove 470. A locking groove 470 extending downward is provided between the inner wall of the rear side slide groove 42 and the bottom plate 1. A locking block 471 is provided in the locking groove 470 for sliding up and down. The locking block 471 is a right-angled trapezoid with an inclined surface facing the front side, and its inclined surface is inclined downward from front to back. The lower end surface of the locking block 471 is fixed together with the inner wall of the locking groove 470. A spring 2 472 is fixedly provided, and a U-shaped bar 473 is slidably provided on the bottom plate 1, which is located on the left side of the locking block 471 and has an opening facing downward. The two vertical sections of the U-shaped bar 473 extend downward to cooperate with the push plate 461, and a push block 474 for pushing the locking block 471 to move downward is fixedly provided on the right end face of the front section of the U-shaped bar 473. The push block 474 is a right-angled trapezoid with an inclined surface facing the rear side, and its inclined surface is inclined downward from front to back.

[0044] In the initial state, the locking block 471 is below the pushing block 474, and the spring 2 472 is compressed and deformed. When working, the pushing plate 461 pushes the vertical bar 48 to move forward. After the pushing plate 461 contacts the vertical section of the front side of the U-shaped bar 473, it pushes the U-shaped bar 473 to move forward synchronously. The U-shaped bar 473 drives the pushing block 474 to move forward synchronously. After the clamping plate 1 43 is close to the metal shell, the locking block 471 moves upward under the elastic force generated by the deformation of the spring 2 472 until the front end surface of the locking block 471 contacts the clamping plate 1 43, and the locking block 471 clamps the rear side The position of plate 1 43 is defined, and the position of the rear rack four 442 is defined by defining the position of the rear clamping plate 1 43. The position of each rack four 442 is defined by the cooperation between the rear rack four 442 and the gear three 441, thereby locking the position of each clamping plate 1 43. Through the cooperation between each clamping plate 143, the metal shell is located at the specified position of the upper end surface of the base plate 1. At this time, the inclined surface of the push block 474 is located above the locking block 471. In the subsequent resetting process, the locking block 471 is pushed downward by the inclined surface of the push block 474.

[0045] After all the screws are installed, the external hydraulic cylinder 1 drives the moving plate 3 to move upward, and the moving plate 3 drives the rack 3 463 to move upward synchronously, and the gear 2 460 is rotated by the meshing between the rack 3 463 and the gear 2 460. At the same time, the gear 2 460 is meshed with the rack 2 462 to move backward, and the rack 2 462 drives the push plate 461 to move backward synchronously. After the push plate 461 moves backward until it contacts the vertical section on the rear side of the U-shaped bar 473, the push plate 461 moves backward. The movable plate 461 pushes the U-shaped bar 473 to move backward, and the U-shaped bar 473 drives the pushing block 474 to move backward synchronously. During the backward movement of the pushing block 474, through the cooperation between the inclined surface of the pushing block 474 and the locking block 471, the pushing block 474 pushes the locking block 471 to move downward until the front end surface of the locking block 471 is out of contact with the clamping plate 43, thereby completing the unlocking of the clamping plate 43, and the locking block 471 moves downward to compress and deform the spring 2 472, thereby completing the resetting of the locking group 47.

[0046] like Figure 2 , Figure 3 and Figure 7 As shown, a guide group 75 is commonly provided between the clamping plate 1 43 and the clamping plate 2 415, and the guide group 75 includes a guide rod 750, and the lower end surfaces of the two front and rear opposite clamping plates 2 415 are fixedly provided with a guide rod 750 with an axis extending from top to bottom, and the front and rear opposite clamping plates 1 43 are each provided with a guide groove 751 with an axis extending from top to bottom, and the guide groove 751 is divided into two sections from top to bottom, the upper section of the guide groove 751 is a truncated cone section with a large diameter section located on the upper side, and the lower section of the guide groove 751 is a cylindrical section.

[0047] During operation, after completing the clamping of the metal shell, the movable plate 3 continues to move downward until the two guide rods 750 contact the guide grooves 751. In the process of the clamping group 1 41 driving the circuit board to move downward, the shape of the conical section of the guide groove 751 and the corresponding guide rod 750 is matched, so that the two front and rear opposite clamping plates 2 415 move to adjust the position of the threaded hole on the circuit board until the guide rod 750 moves to match the cylindrical section of the corresponding guide groove 751, completing the preliminary limiting of the threaded hole on the circuit board, so that the position of the threaded hole on the circuit board corresponds to the position of the threaded hole on the metal shell.

[0048] like Figure 2 , Figure 3 and Figure 5 As shown, a positioning group 76 is commonly provided between the vertical column 5 and the rotating rod 70, and the positioning group 76 includes a rectangular plate 760, a rectangular plate 760 is slidably sleeved on the vertical column 5, and a circular plate located on the lower side of the rectangular plate is fixedly sleeved on the vertical column 5, and a spring 761 sleeved on the vertical column is commonly fixedly provided between the rectangular plate 760 and the circular plate, and the upper end portion of the rotating rod 70 is fixedly sleeved with a limiting cylinder 762 located on the lower side of the sliding plate 6, and the rear section of the limiting cylinder 762 is provided with a U-shaped limiting groove 763 with an opening facing upward, and a positioning strip 764 cooperating with the limiting groove 763 is fixedly provided on the front end surface of the rectangular plate 760.

[0049] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a limit stop group 77 is commonly set between the rotating rod 70 and the movable plate 3, and the limit stop group 77 includes a moving block 770, and a moving block 770 is slidably arranged on the lower section of the rotating rod 70 up and down, and a spiral spring 771 is commonly fixedly arranged between the moving block 770 and the rotating plate 2 73 and is sleeved on the rotating rod 70; the end surface of the middle section of the rotating plate 1 71 away from the vertical column 5 is fixedly provided with a vertical rod 772 with an axis extending from top to bottom through a horizontal plate; a lower pressing plate 773 is slidably sleeved on the vertical rod 772 for pressing down the rotating plate 2 73; a blocking plate 774 is fixedly arranged on the lower end surface of the lower pressing plate 773 for blocking the rotating plate 2 73 from rotating; a spring 4 775 sleeved on the vertical rod 772 is commonly fixedly arranged between the lower pressing plate 773 and the horizontal plate; and a blocking rod 776 is fixedly arranged on the upper end surface of the movable plate 3 with an axis extending from top to bottom and used to block the rotating plate 2 73 from continuing to rotate.

[0050] When the cam 720 is in a closed position, the spring 771 is in a closed position, and the spring 772 is in a closed position, the cam 720 is in a closed position, and the cam 720 is in a closed position, the cam 720 is in a closed position, the cam 720 is in a closed position, the cam 720 is in a closed position, the cam 720 is in a closed position, the cam 720 is in a closed position, the cam 720 is in a closed position, the cam 720 is in a closed position, the cam 720 is in a closed position, the cam 720 is in a closed position, the cam 720 is in a closed position, the cam 720 is in a closed position, the cam 720 is in a closed position, the cam 720 is in a closed position, the cam 720 is in a closed position, the cam 720 is in a closed position, the cam 720 is in a closed position, the cam 720 is in a closed position, When it is in the specified position and moves downward, the sliding plate 6 drives the positioning bar 764 to move downward synchronously by pushing the rectangular plate 760. The movement of the rectangular plate 760 causes the spring three 761 to be compressed and deformed. At the same time, the rotating plate one 71 drives the vertical rod 772 to move downward synchronously through the horizontal plate. The force generated by the deformation of the spring four 775 acts on the rotating plate two 73 through the lower pressure plate 773, so that the rotating plate two 73 moves downward synchronously with the rotating plate. At the same time, the elastic force generated by the deformation of the spiral spring 771 acts on the rotating plate two 73, so that the rotating plate two 73 rotates to be close to the blocking plate 774, so that the rotating plate two 73 drives the two positioning rods 74 to move downward at a specified angle.

[0051] The rotating plate 2 73 drives the two positioning rods 74 to move downward through the corresponding positioning slots 8 and then continue to move downward. The two positioning rods 74 move downward through the two threaded holes at corresponding positions on the circuit board and the metal shell to limit the positions of the four threaded holes on the circuit board. The rotating plate 1 71 drives the two electric screwdrivers 72 to move downward to the working position and fix the corresponding positions of the circuit board and the metal shell with two screws.

[0052] After the screws at two positions on the circuit board and the metal shell are installed, the two installed screws at the diagonal positions cooperate with the metal shell and the circuit board to fix the circuit board, so that the circuit board is located at a specified position on the metal shell, and then the two uninstalled threaded holes on the circuit board are located at specified positions. The external hydraulic cylinder 2 drives the rotating plate 1 71 and the rotating plate 2 73 to move upward through the sliding plate 6. The elastic force generated by the deformation of the spring 3 761 acts on the rectangular plate 760 and pushes the positioning bar 764 to move upward synchronously through the rectangular plate 760. After the positioning bar 764 moves upward and stops moving after the spring three 761 is reset, the sliding plate 6 continues to move upward until the positioning bar 764 is out of contact with the rear vertical section of the limiting groove 763, and the sliding plate 6 stops moving. Then the external motor 1 works to drive the rotating rod 70 to rotate until the positioning bar 764 contacts the front inner wall of the limiting groove 763, and the rotating rod 70 drives the rotating plate 1 71 and the rotating plate 2 73 to rotate synchronously. During the rotation process, the rotating plate 2 73 rotates until it contacts the blocking rod 776, and then the rotating plate 2 73 stops rotating, and the rotating rod 70 continues to rotate to make the spiral roll The spring 771 is continuously stretched and deformed, and the rotating plate 1 71 drives the two electric screwdrivers 72 to rotate above the corresponding threaded holes where the screws are not installed. Then, the external hydraulic cylinder 2 works to drive the two electric screwdrivers 72 to move downward through the rotating plate 1 71. Through the shape matching between the positioning bar 764 and the vertical section on the front side of the limiting groove 763, the rotating plate 1 71 drives the two electric screwdrivers 72 to move downward at the specified position. The two electric screwdrivers 72 continue to move downward to the working position and fix the corresponding positions of the circuit board and the metal shell through two screws. The two electric screwdrivers 72 are fixedly connected, and the rotating plate 71 drives the two electric screwdrivers 72 to move downward. At the same time, the rotating plate 73 moves downward synchronously, and the two positioning rods 74 are prevented from moving downward by the moving plate 3, so that relative movement is generated between the rotating plate 2 73 and the rotating plate 1 71. The spring four 775 is continuously stretched and deformed through the relative movement between the rotating plate 2 73 and the rotating plate 1 71. In the subsequent resetting process, the elastic force of the spring four 775 acts on the rotating plate 2 73 through the lower pressure plate 773, so that the rotating plate 2 73 moves to be close to the rotating plate 1 71.

[0053] After completing the installation of screws at all positions, the external hydraulic cylinder 2 drives the rotating plate 1 71 and the rotating plate 2 73 to move upward and reset through the sliding plate 6. After the sliding plate 6 moves to the initial position, the external motor 1 drives the rotating plate 1 71 and the rotating plate 2 73 to rotate to the initial position through the rotating rod 70. Then the external motor 2 drives the clamping group 1 41 to loosen the clamping of the circuit board, and the external hydraulic cylinder 1 drives the moving plate 3 to move upward and reset.
