[0002] A connector is a detachable component installed on a cable or device for electrical connection of a transmission line system. Among them, pin header connectors are a type of connector widely used in electronics, electrical appliances, instruments and other fields. They are mainly used on PCB circuit boards as a bridge connecting the circuit inside or between circuits, responsible for transmitting current or signals. Pin header connectors are usually used in conjunction with female headers to form a board-to-board connection, or used in conjunction with electronic wiring harness terminals to form a board-to-wire connection, or can be used independently for board-to-board connection. With the development of technology, manufacturers continue to adopt new technologies and equipment to improve production efficiency and product quality to meet the market demand for high-performance connectors.

[0019] Compared with the prior art, the present invention provides an assembly system for connector production, which has the following beneficial effects:

[0020] 1. The assembly system for connector production is provided with a cutting assembly with a pad on the first conveyor belt. The downward movement of the cutting knife drives the gear and the rack to mesh and rotate.

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] Embodiment 1:

[0037] Reference Figure 1-Figure 7A connector production assembly system includes a first conveyor platform 1 and a second conveyor platform 2. Conveyor rollers 4 are provided in the first conveyor platform 1 and the second conveyor platform 2. A first conveyor belt 3 is connected to the first conveyor platform 1 through the conveyor rollers 4, and a second conveyor belt 10 is connected to the second conveyor platform 2 through the conveyor rollers 4.

[0038] In this embodiment, a first conveying platform 1 and a second conveying platform 2 are respectively provided. The first conveying platform 1 is used to convey the needle strip, and the second conveying platform 2 is used to convey the connecting seat. After being conveyed to the assembly station, the needle strip is pushed into the connecting seat.

[0039] It should be noted that a transition platform 6 is provided between the first conveyor belt 3 and the second conveyor belt 10 to provide support force for the needle row material belt during the pushing and assembling process.

[0040] It also includes: a cutting assembly mounted above the first conveyor belt 3, the cutting assembly is used to cut the needle strip before assembly; the cutting assembly includes a bracket 13 and a cutting knife 14, the cutting knife 14 slides vertically on one side of the bracket 13 through an electric slide 16, a reinforcing plate 15 is fixedly installed on one side of the bracket 13, and the electric slide 16 is symmetrically installed on one side of the reinforcing plate 15.

[0041] In this embodiment, a bracket 13 is provided on the first conveyor belt 3, and the cutting knife 14 slides vertically on one side of the bracket 13 through two sets of electric slides 16. The electric slides 16 are started to drive the cutting knife 14 to cut downwards and reset upwards.

[0042] Specifically, a reinforcing plate 15 is installed on one side of the bracket 13 , and an electric slide 16 is installed on one side of the reinforcing plate 15 to enhance the supporting force of the cutting blade 14 .

[0043] A pad 23 is provided on the inner bottom surface of the first conveyor belt 3 , and support shafts 22 are symmetrically provided on both sides of the pad 23 , and the installation positions of the pad 23 and the cutting knife 14 are matched.

[0044] In the present embodiment, in order to prevent the tension of the conveyor belt from being insufficient to support the cutting force when the cutting knife 14 cuts the needle row material belt, a pad 23 is provided at the bottom of the first conveyor belt 3, and a support shaft 22 is connected to the bottom of the pad 23.

[0045] An elastic connection component is arranged between the support shaft 22 and the slider of the electric slide 16, and the elastic connection component includes a connecting shaft 17 and a gear 18 fixedly installed on the shaft end of the connecting shaft 17. A rack 19 is installed on one side of the bracket 13, and the gear 18 and the rack 19 are meshed. An eccentric rod 20 is fixedly connected to one side of the gear 18, and the eccentric rod 20 is elastically connected to the support shaft 22 through a tension spring 21.

[0046] In this embodiment, an elastic connection assembly is provided between the support shaft 22 and the slider of the electric slide table 16. Specifically, it includes a connecting shaft 17. One end of the connecting shaft 17 is fixedly installed with a gear 18. The gear 18 meshes with a rack 19. After starting the electric slide table 16 and driving the cutting tool 14 to move downward for cutting, the connecting shaft 17 drives the gear 18 to move downward. The gear 18 meshes with the rack 19, and the gear 18 rotates, driving the eccentric rod 20 on one side of the gear 18 to rotate around the connecting shaft 17. During the rotation of the eccentric rod 20, the tension spring 21 is pulled, so as to drive the support shaft 22 to drive the backing plate 23 to float upward through pulling, enabling the cutting tool 14 to quickly cut off the pin strip.

[0047] It should be noted that the eccentric rod 20 is located at the lowest position of the gear 18 in the initial state. During the downward movement of the slider of the electric slide table 16, the gear 18 rotates half a turn, turning the eccentric rod 20 to the highest position of the gear 18 to complete the cutting; in this embodiment, the cutting tool 14 drives the backing plate 23 to float upward while cutting, providing the support stiffness at the moment of cutting.

[0048] Two sets of traction components are provided above the first conveyor belt 3. The traction directions of the two sets of traction components are opposite. Before cutting the pin strip, the two sets of traction components are used to tension the pin strip. Two sets of traction components are provided. One set of traction components is arranged at the feeding end of the first conveyor belt 3, and the other set of traction components is arranged on one side of the cutting tool 14. The traction component includes a top plate 12 and a traction roller 5 rotatably arranged below the top plate 12.

[0049] In this embodiment, two sets of traction components are provided, respectively on both sides of the cutting component, pressing and conveying the pin strip on the surface of the conveyor belt during the conveying process, so as to avoid the phenomenon that the pin strip generates wrinkles or accumulates on the conveying channel during the conveying process;

[0050] An adjustment assembly is provided between the top plate 12 and the first conveying table 1. The adjustment assembly includes a lead screw 7. The surface of the lead screw 7 is connected with a moving block 8 through an internal thread sleeve 9. A top rod 11 is fixedly connected inside the moving block 8, and the top end of the top rod 11 is fixedly connected to the lower surface of the top plate 12.

[0051] In this embodiment, an adjustment assembly is provided between the top plate 12 and the first conveying table 1. Since the moving block 8 is slidably installed on the side wall of the first conveying table 1 and the lead screw 7 rotates, and the internal thread sleeve 9 is rotatably connected inside the moving block 8, therefore, the moving block 8 can vertically move along the lead screw 7, rising or descending. The moving block 8 drives the top plate 12 and the traction roller 5 below the top plate 12 to move up and down through the top rod 11, enabling the two sets of traction rollers 5 to adapt to pin strips of different sizes.

[0052] A pressing component is arranged between the support shaft 22 and the top plate 12. The pressing component includes a first connecting plate 34 and a second connecting plate 35. The second connecting plate 35 is fixedly connected to one side of the top plate 12. One end of the first connecting plate 34 is rotatably connected to the support shaft 22, and the middle of the first connecting plate 34 is pinned to the second conveying table 2 through a support plate 36. Ear plates 38 are fixedly installed at one ends of the first connecting plate 34 and the second connecting plate 35, and the two groups of ear plates 38 are pinned through a pin shaft 37.

[0053] In this embodiment, a pressing component is arranged between the support shaft 22 and the top plate 12. When the support shaft 22 is lifted, the support shaft 22 drives the first connecting plate 34 to be lifted. Since the middle of the first connecting plate 34 is pinned to the second conveying table 2 by the support plate 36, the other end of the first connecting plate 34 is pressed down, and the second connecting plate 35 is pulled down by the two groups of ear plates 38 and the pin shaft 37, so as to drive the top plate 12 to drive the traction roller 5 to move downward, and the traction roller 5 is used to press the pin strip tightly against the first conveyor belt 3, effectively preventing the pin strip from deforming under the cutting pressure during cutting.

[0054] A cylinder 24 is arranged on one side of the second conveying table 2. A push plate 25 is fixedly installed at the output shaft end of the cylinder 24. One side of the push plate 25 is connected to a buffer plate 26 through a first spring 28. First guide rods 27 are symmetrically connected to the side of the buffer plate 26 close to the push plate 25. One end of the first guide rod 27 is slidably connected to the push plate 25, and the first guide rod 27 penetrates through the first spring 28.

[0055] In this embodiment, a cylinder 24 is arranged on one side of the first conveyor belt 3. The cylinder 24 is started to drive the buffer plate 26 to push the pin strip and load it into the connecting seat conveyed by the second conveyor belt 10.

[0056] It should be noted that the hardness of the pin strip is relatively low. A push plate 25 is connected to the output shaft end of the cylinder 24. The push plate 25 is connected to the buffer plate 26 through a first spring 28 to provide a pushing buffer for the pin strip and prevent the pin strip from being damaged under the condition of instantaneous impact during the assembly process.

[0057] It should be noted that an elastic connection component is arranged between the cylinder 24 and the second conveying table 2. The elastic connection component includes a bottom plate 39 and a second guide rod 41 slidably installed in the bottom plate 39. A second spring 40 is sleeved on the outer wall of the second guide rod 41. The top end of the bottom plate 39 is fixedly connected to the bottom of the cylinder 24. So that during the downward movement of the traction roller 5, the cylinder 24 can move synchronously without interference.

[0058] A first guide rod 27 is arranged on one side of the buffer plate 26. The first guide rod 27 is slidably connected to the push plate 25 to ensure that the direction of the thrust is always unified with the assembly direction of the pin strip, thereby ensuring the assembly accuracy.

[0059] A blowing component is arranged between the push plate 25 and the mandrel. The blowing component includes a connecting frame 29 which is fixedly connected to one side of the push plate 25. One side of the connecting frame 29 is fixedly connected with a piston rod 30. One end of the piston rod 30 is slidably connected to one end of the mandrel. One end of the piston rod 30 extending into the mandrel is rotatably connected with a piston plate 31. The piston plate 31 is slidably and threadedly connected inside the mandrel. The surface of the traction roller 5 is wrapped with a rubber sleeve 32. Air holes 33 are annularly and equidistantly formed in the axial walls of the mandrel and the rubber sleeve 32.

[0060] In this embodiment, in order to clean the surface of the pin strip before assembly, the traction roller 5 near the cutting knife 14 is set as a mandrel with a hollow structure. During assembly, the air cylinder 24 is started, and the push plate 25 at the output shaft end of the air cylinder 24 moves forward. The push plate 25 drives the piston rod 30 to move forward through the connecting frame 29. The piston rod 30 drives the piston plate 31 to perform a piston motion inside the mandrel. During the movement of the piston plate 31, the air inside the mandrel is blown to the surface of the pin strip to be assembled through the air holes 33 by the air flow, instantly removing the dust attached to the surface of the pin strip.

[0061] It should be noted that since the mandrel is always in a rotating state during use, in order to ensure that the air flow effectively blows the pin strip, air holes 33 are annularly and equidistantly formed in the mandrel and the rubber sleeve 32 wrapped around the outer wall of the mandrel.

[0062] It should be noted that when the air cylinder 24 is started to drive the piston plate 31 to move forward, a threaded drive is generated between the piston plate 31 and the inner wall of the traction roller 5, so that the traction roller 5 rotates in the reverse direction during the movement of the piston plate 31. While pressing the pin strip, the pin strip is pulled, and the pin strip is flattened, effectively avoiding the misalignment of the position of the pin strip during the instant of cutting and ensuring the cutting accuracy.

[0063] In the present invention, the pin strip is placed on the first conveyor table 1, and the connecting seat is placed on the second conveyor table 2. The first conveyor table 1 and the second conveyor table 2 are started to drive the pin strip and the connecting seat to move forward to prepare for assembly;

[0064] Both groups of traction rollers 5 are drivingly connected with servo motors. During the conveying process, the two groups of traction rollers 5 rotate in the same direction to convey and traction different sections of the pin strip, thereby avoiding the phenomenon that the pin strip generates wrinkles or accumulates on the conveying channel during the conveying process;

[0065] Before cutting, the pin strip is closely pressed and rotated in opposite directions by a certain angle. The electric sliding table 16 is started to drive the cutting knife 14 to move down for cutting the pin strip, effectively avoiding the misalignment of the position of the pin strip during the cutting process and ensuring the cutting accuracy;

[0066] When starting the electric slide table 16 to drive the cutting tool 14 to move downward for cutting, the connecting shaft 17 drives the gear 18 to move downward. The gear 18 meshes with the rack 19, and the gear 18 rotates, driving the eccentric rod 20 on one side of the gear 18 to rotate around the connecting shaft 17. During the rotation of the eccentric rod 20, the tension spring 21 is pulled, so that the supporting shaft 22 is pulled to drive the backing plate 23 to float upward, enabling the cutting tool 14 to quickly cut off the pin strip;

[0067] A push plate 25 is connected to the output shaft end of the air cylinder 24. The push plate 25 is connected to the buffer plate 26 through the first spring 28, providing push buffering for the pin strip to prevent damage to the pin strip during the instant impact in the assembly process;

[0068] In order to clean the surface of the pin strip before assembly, the traction roller 5 on the side close to the cutting tool 14 is set as a mandrel with a hollow structure. When assembling the pin strip, the air cylinder 24 is started. The push plate 25 at the output shaft end of the air cylinder 24 moves forward. The push plate 25 drives the piston rod 30 to move forward through the connecting frame 29. The piston rod 30 drives the piston plate 31 to perform a piston movement in the mandrel. During the movement of the piston plate 31, the air in the mandrel is blown to the surface of the pin strip to be assembled through the air holes 33 via the air flow, instantly removing the dust attached to the surface of the pin strip.

[0069] Embodiment 2:

[0070] Refer to Figure 1-Figure 8 , in this embodiment, air holes 33 are no longer opened on the rubber sleeve 32, and only a threaded structure is opened on the inner wall. A guiding frame 42 is fixedly connected to the top of the transition table 6 to guide the cut pin strip to be inserted into the connector. And in the guiding cavity of the guiding frame 42, a first floating groove 43 with a gradually increasing height in the moving direction is opened below. A plurality of buoyancy tubes 45 are arranged equidistantly in the first floating groove 43. Each buoyancy tube 45 is communicated through a shunt tube 44, and the shunt tube is communicated with the piston rod 30. When the piston plate 31 compresses the gas inside the rubber sleeve 32, the gas is blown out from the buoyancy tubes 45 through the shunt tube 44, so that the stepped pin strip passing through is in a suspended state, ensuring its transition between the two conveying platforms and accurate insertion into the holes of the connector. And a second floating groove 46 with an arc-shaped structure is opened at the top of the cavity of the guiding frame 42, which can guide the dissipated air flow to blow towards the pin strip from the top to prevent the pin strip from tilting too high. By this method, not only is the pin strip accurately stretched and cut, but also the subsequent assembly is ensured to be more accurate.

[0071] An assembly method for producing a connector includes the following steps:

[0072] Step 1: Convey the pin strip and the connector housing respectively;

[0073] Step 2: After the pin strip is conveyed to the assembly station, it is tensioned and then cut.

[0074] Step 3: Push the cut pin strip into the connector housing to complete the assembly.

[0075] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
