Description

Technical Field

[0001] This invention relates to the field of connector manufacturing technology, and in particular to an assembly system and method for connector manufacturing. Background Technology

[0002] A connector is a separable component mounted on a cable or device for electrical connection in a transmission line system. Among them, pin header connectors are widely used in electronics, electrical appliances, instrumentation, and other fields. They are primarily used on PCB circuit boards as bridges connecting circuits within or between circuits, responsible for transmitting current or signals. Pin header connectors are typically used with female headers to form board-to-board connections, or with electronic wire harness terminals to form board-to-wire connections, or can be used independently for board-to-board connections. With technological advancements, manufacturers are continuously adopting new technologies and equipment to improve production efficiency and product quality, meeting market demands for high-performance connectors.

[0003] The existing assembly system cannot effectively limit the needle strip to the conveyor channel during the needle strip conveying process. This causes the needle strip to move during the conveying process, resulting in wrinkles or accumulation on the conveyor channel. Furthermore, the looseness of the needle strip during the conveying process also affects the positioning accuracy of the subsequent needle strip cutting, making it easy to cut the needle strip in the wrong position during the cutting process. This leads to the need for frequent manual inspections, which increases the trouble for workers. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art where the pin header strip cannot be well positioned on the conveying channel, causing the pin header strip to move during the conveying process, resulting in wrinkles or accumulation on the conveying channel. Furthermore, the looseness of the pin header strip during the conveying process also affects the positioning accuracy of subsequent pin header strip cutting, making it easy to cut the pin header strip in the wrong position during the cutting process, which requires frequent manual inspection and increases the trouble for workers. Therefore, this invention proposes an assembly system and method for connector production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An assembly system for connector manufacturing includes a first conveyor table and a second conveyor table. Both the first and second conveyor tables are equipped with conveyor rollers. A first conveyor belt is driven to the first conveyor table via the conveyor rollers, and a second conveyor belt is driven to the second conveyor table via the conveyor rollers. A transition platform is provided between the first and second conveyor belts. The system also includes: a cutting assembly mounted above the first conveyor belt, used to cut the pin header material strip before assembly; and two sets of traction assemblies mounted above the first conveyor belt, with opposite traction directions, used to tension the pin header material strip before cutting it.

[0007] Preferably, the cutting assembly includes a bracket and a cutting blade. The cutting blade slides vertically on one side of the bracket via an electric slide table. A reinforcing plate is fixedly installed on one side of the bracket, and the electric slide table is symmetrically installed on one side of the reinforcing plate.

[0008] To prevent the tension of the conveyor belt from being insufficient to support the cutting force when the cutting blade cuts the needle strip, a pad is further provided on the inner bottom surface of the first conveyor belt, and support shafts are symmetrically arranged on both sides of the pad. The installation positions of the pad and the cutting blade are matched.

[0009] To enable the cutting blade to lift the pad while cutting, providing support rigidity during the cutting moment, an elastic connection assembly is further provided between the support shaft and the slider of the electric slide. The elastic connection assembly includes a connecting shaft and a gear fixedly installed on the end of the connecting shaft. A rack is installed on one side of the bracket, and the gear and rack mesh. An eccentric rod is fixedly connected to one side of the gear, and the eccentric rod is elastically connected to the support shaft through a tension spring.

[0010] Preferably, the traction assembly is provided in two sets, one set of the traction assembly is provided at the feed end of the first conveyor belt, and the other set of the traction assembly is provided on the side of the cutting blade. The traction assembly includes a top plate and a traction roller rotatably provided below the top plate. An adjustment assembly is provided between the top plate and the first conveyor table. The adjustment assembly includes a lead screw. A moving block is connected to the surface of the lead screw through an internal thread sleeve. A top rod is fixedly connected inside the moving block. The top end of the top rod is fixedly connected to the lower surface of the top plate.

[0011] To prevent deformation of the needle strip under cutting pressure during cutting, a clamping assembly is further provided between the support shaft and the top plate. The clamping assembly includes a first connecting plate and a second connecting plate. The second connecting plate is fixedly connected to one side of the top plate. One end of the first connecting plate is rotatably connected to the support shaft, and the middle part of the first connecting plate is pinned to the second conveyor table through a support plate. Ear plates are fixedly installed at one end of both the first and second connecting plates, and the two sets of ear plates are pinned together by a pin shaft.

[0012] Preferably, a cylinder is provided on one side of the second conveyor table, and a push plate is fixedly installed on the output shaft end of the cylinder. A buffer plate is connected to one side of the push plate through a first spring. A first guide rod is symmetrically connected to the side of the buffer plate near the push plate. One end of the first guide rod is slidably connected inside the push plate, and the first guide rod passes through the first spring.

[0013] To further clean the surface of the needle strip before assembly, the traction roller near the cutting blade is configured as a hollow mandrel, and the surface of the traction roller is covered with a rubber sleeve.

[0014] While assembling using a cylinder, airflow is released through the mandrel to remove dust adhering to the surface of the needle strip. Furthermore, an air blowing assembly is provided between the push plate and the mandrel. The air blowing assembly includes a connecting frame, on which one side of the push plate is fixedly connected. A piston rod is fixedly connected to one side of the connecting frame. One end of the piston rod is slidably connected to one end of the mandrel. The end of the piston rod extending into the mandrel is rotatably connected to a piston plate. The piston plate is slidably and threadedly connected to the inside of the mandrel. Air holes are equidistantly spaced in annular pattern on the shaft walls of the mandrel and the rubber sleeve.

[0015] An assembly method for connector manufacturing includes the following steps:

[0016] Step 1: Convey the needle-pack material and the connecting seat separately;

[0017] Step 2: After the needle-pack material is conveyed to the assembly station, it is tensioned and then cut;

[0018] Step 3: Push the cut needle strip into the connector to complete the assembly.

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

[0020] 1. The assembly system for connector production uses a cutting assembly with a pad on a first conveyor belt. As the cutting blade moves downward, it drives the gear and rack to mesh and rotate. During the rotation of the eccentric rod, the tension spring is pulled, which in turn pulls the support shaft and causes the pad to float, allowing the cutting blade to quickly cut the needle strip. The cutting blade also causes the pad to float while cutting, providing support rigidity at the moment of cutting.

[0021] 2. The assembly system for connector production uses two sets of traction components on both sides of the cutting component. During the conveying process, the traction rollers rotate in the same direction to convey and pull different segments of the pin pack material strip, thereby avoiding the phenomenon of the pin pack material strip getting wrinkled or piling up on the conveying channel during the conveying process.

[0022] 3. The assembly system for connector production uses two sets of traction components on both sides of the cutting component. Before cutting, the pin strip is pressed and pressed together. The internal thread drive causes the traction roller to rotate in opposite directions at a certain angle. After the pin strip is flattened and pressed, the cutting blade moves down to cut the pin strip. This effectively avoids the pin strip being cut incorrectly during the cutting process and ensures cutting accuracy.

[0023] 4. The assembly system for connector production uses a set of traction rollers as a hollow mandrel. A piston rod and piston plate are installed inside the mandrel. The piston plate is driven to move inside the mandrel by the connecting frame at the output shaft of the cylinder. The airflow is blown through the air hole to the surface of the pin header strip to be assembled, instantly removing the dust attached to the surface of the pin header strip.

[0024] The parts of this device not described herein are the same as or can be implemented using existing technologies. This invention utilizes a cutting assembly with a pad on the first conveyor belt. During rotation of the eccentric rod, the spring is pulled, causing the support shaft to lift the pad, allowing the cutting blade to quickly cut the needle strip. Simultaneously, it provides instantaneous support stiffness to the needle strip. During conveying, the traction rollers rotate in the same direction, conveying and pulling the needle strip in different segments, thus preventing wrinkles or accumulation on the conveying channel. Before cutting, the needle strip is pressed tightly together and rotated a certain angle in the opposite direction. The electric slide is then activated, causing the cutting blade to move downwards to cut the needle strip, effectively preventing mis-cutting and ensuring cutting accuracy. The connecting bracket at the cylinder output shaft drives the piston plate to move within the mandrel, and airflow is blown through the air holes to the surface of the needle strip to be assembled, instantly removing dust adhering to the surface.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0036] Example 1:

[0037] Reference Figures 1-7An assembly system for connector production includes a first conveyor table 1 and a second conveyor table 2. Both the first conveyor table 1 and the second conveyor table 2 are provided with conveyor rollers 4. A first conveyor belt 3 is driven and connected to the first conveyor table 1 through the conveyor rollers 4, and a second conveyor belt 10 is driven and connected to the second conveyor table 2 through the conveyor rollers 4.

[0038] In this embodiment, a first conveyor 1 and a second conveyor 2 are respectively provided. The first conveyor 1 is used to convey the needle strip, and the second conveyor 2 is used to convey the connector. When the needle strip is conveyed to the assembly station, it is pushed into the connector.

[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 for the needle pack material during the assembly process.

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

[0041] In this embodiment, a support 13 is provided on the first conveyor belt 3. The cutting blade 14 slides vertically on one side of the support 13 via two sets of electric slide tables 16. When the electric slide tables 16 are activated, the cutting blade 14 is driven to cut downwards and then 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 support for the cutting blade 14.

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

[0044] In this embodiment, to prevent the tension of the conveyor belt from being insufficient to support the cutting force when the cutting blade 14 cuts the needle strip, 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 assembly is provided between the support shaft 22 and the slider of the electric slide table 16. The elastic connection assembly 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. The gear 18 and the rack 19 mesh. An eccentric rod 20 is fixedly connected to one side of the gear 18. The eccentric rod 20 is elastically connected to the support shaft 22 through a tension spring 21.

[0046] In this embodiment, an elastic connection component is provided between the support shaft 22 and the slider of the electric slide table 16. Specifically, it includes a connecting shaft 17, with a gear 18 fixedly installed at one end of the connecting shaft 17. The gear 18 meshes with the rack 19. When the electric slide table 16 is started and the cutting blade 14 is moved down to cut, the connecting shaft 17 drives the gear 18 to move down. The gear 18 meshes with the rack 19, and the gear 18 rotates, causing 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, thereby pulling the support shaft 22 to cause the pad 23 to float up, so that the cutting blade 14 can quickly cut the needle strip.

[0047] It should be noted that the eccentric rod 20 is initially located at the lowest position of the gear 18. During the downward movement of the slider of the electric slide table 16, the gear 18 rotates half a turn, rotating the eccentric rod 20 to the highest position of the gear 18 to complete the cutting. In this embodiment, the cutting blade 14 drives the pad 23 to float up while cutting, providing support rigidity at the moment of cutting.

[0048] Two sets of traction components are arranged above the first conveyor belt 3, with opposite traction directions. Before cutting the needle strip, the two sets of traction components are used to tension the needle strip. There are two sets of traction components, one set is located at the feed end of the first conveyor belt 3, and the other set is located on one side of the cutting blade 14. The traction components include 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 set on both sides of the cutting component to press the needle strip onto the surface of the conveyor belt during the conveying process, thereby avoiding the formation of wrinkles or accumulation of the needle strip on the conveying channel during the conveying process.

[0050] An adjustment assembly is provided between the top plate 12 and the first conveyor table 1. The adjustment assembly includes a lead screw 7. A moving block 8 is connected to the surface of the lead screw 7 through an internal threaded sleeve 9. A top rod 11 is fixedly connected inside the moving block 8. 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 conveyor table 1. Since the moving block 8 is slidably installed on the side wall of the first conveyor table 1, the lead screw 7 rotates, and the internal threaded sleeve 9 is rotatably connected to the moving block 8. Therefore, the moving block 8 can move vertically along the lead screw 7, rising or falling. 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, so that the two sets of traction rollers 5 can be adapted to different sizes of needle strips.

[0052] A clamping assembly is provided between the support shaft 22 and the top plate 12. The clamping assembly 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 part of the first connecting plate 34 is pinned to the second conveyor table 2 through the support plate 36. Ear plates 38 are fixedly installed at one end of both the first connecting plate 34 and the second connecting plate 35. The two sets of ear plates 38 are pinned together by the pin shaft 37.

[0053] In this embodiment, a clamping assembly is provided 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 part of the first connecting plate 34 is pinned to the second conveyor table 2 by the support plate 36, the other end of the first connecting plate 34 is pressed down. The two sets of ear plates 38 and the pin shaft 37 pull down the second connecting plate 35, thereby pulling the top plate 12 to drive the traction roller 5 to move downward. The traction roller 5 presses down the needle strip and the first conveyor belt 3 to fit tightly together, effectively preventing the needle strip from deforming under the cutting pressure during cutting.

[0054] A cylinder 24 is provided on one side of the second conveyor table 2. A push plate 25 is fixedly installed on the output shaft end of the cylinder 24. A buffer plate 26 is connected to one side of the push plate 25 through a first spring 28. A first guide rod 27 is symmetrically connected to the side of the buffer plate 26 near the push plate 25. One end of the first guide rod 27 is slidably connected inside the push plate 25, and the first guide rod 27 passes through the first spring 28.

[0055] In this embodiment, a cylinder 24 is provided on one side of the first conveyor belt 3. When the cylinder 24 is activated, the buffer plate 26 pushes the needle strip to load it into the connecting seat conveyed on the second conveyor belt 10.

[0056] It should be noted that the needle strip has low hardness. A push plate 25 is connected to the output shaft end of the cylinder 24. The push plate 25 is connected to the first spring 28 and the buffer plate 26 to provide pushing and buffering for the needle strip, preventing damage to the needle strip under instantaneous impact during assembly.

[0057] It should be noted that an elastic connecting assembly is provided between the cylinder 24 and the second conveyor table 2. The elastic connecting assembly includes a base plate 39 and a second guide rod 41 slidably installed within the base plate 39. A second spring 40 is sleeved on the outer wall of the second guide rod 41. The top of the base plate 39 is fixedly connected to the bottom of the cylinder 24. This ensures that the cylinder 24 can move synchronously without interference during the downward movement of the traction roller 5.

[0058] A first guide rod 27 is provided 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 pushing force is always consistent with the assembly direction of the needle strip, thereby ensuring the assembly accuracy.

[0059] An air blowing assembly is provided between the push plate 25 and the spindle. The air blowing assembly includes a connecting frame 29, which is fixedly connected to one side of the push plate 25. A piston rod 30 is fixedly connected to one side of the connecting frame 29. One end of the piston rod 30 is slidably connected to one end of the spindle. The end of the piston rod 30 extending into the spindle is rotatably connected to a piston plate 31. The piston plate 31 is slidably and threadedly connected to the spindle. The surface of the traction roller 5 is covered with a rubber sleeve 32. Air holes 33 are equidistantly opened in the annular shape inside the shaft wall of the spindle and the rubber sleeve 32.

[0060] In this embodiment, in order to clean the surface of the needle strip before assembly, the traction roller 5 near the cutting blade 14 is set as a hollow mandrel. During assembly, the cylinder 24 is activated, and the push plate 25 at the output shaft end of the 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 make piston movement inside the mandrel. During the movement of the piston plate 31, the air inside the mandrel is blown to the surface of the needle strip to be assembled through the airflow via the air hole 33, instantly removing the dust attached to the surface of the needle strip.

[0061] It should be noted that, since the mandrel is always rotating during use, in order to ensure that the airflow effectively blows air onto the needle strip, air holes 33 are equidistantly arranged in annular pattern inside the mandrel and the rubber sleeve 32 that wraps the outer wall of the mandrel.

[0062] It should be noted that when the starting cylinder 24 drives the piston plate 31 to move forward, the piston plate 31 and the inner wall of the traction roller 5 generate a thread drive, causing the traction roller 5 to rotate in the opposite direction during the movement of the piston plate 31. While pressing the needle strip, it also pulls the needle strip and flattens it, effectively avoiding the mis-cut position of the needle strip at the moment of cutting and ensuring cutting accuracy.

[0063] In this invention, the needle strip is placed on the first conveyor table 1, the connecting seat is placed on the second conveyor table 2, and the first conveyor table 1 and the second conveyor table 2 are started to move the needle strip and the connecting seat forward in preparation for assembly.

[0064] Both sets of traction rollers 5 are connected to servo motors. During the conveying process, the two sets of traction rollers 5 rotate in the same direction to convey and pull different sections of the needle strip, thereby avoiding the phenomenon of the needle strip getting wrinkled or piling up on the conveying channel during the conveying process.

[0065] Before cutting, the needle strip is pressed tightly together and rotated at a certain angle in the opposite direction. The electric slide table 16 is started to drive the cutting blade 14 to move down to cut the needle strip. This effectively avoids the needle strip being cut in the wrong position during the cutting process and ensures the cutting accuracy.

[0066] When the electric slide table 16 is started and the cutting blade 14 moves down to cut, the connecting shaft 17 drives the gear 18 to move down. The gear 18 and the rack 19 mesh, and the gear 18 rotates, which drives 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, which in turn pulls the support shaft 22 to drive the pad 23 to float up, so that the cutting blade 14 can quickly cut the needle strip.

[0067] A push plate 25 is connected to the output shaft end of the cylinder 24. The push plate 25 is connected to the first spring 28 and the buffer plate 26 to provide pushing buffer for the needle strip and prevent the needle strip from being damaged by instantaneous impact during the assembly process.

[0068] To clean the surface of the needle strip before assembly, the traction roller 5 near the cutting blade 14 is set as a hollow mandrel. When assembling the needle strip, the cylinder 24 is activated, and the push plate 25 at the output shaft end of the 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 make piston movement inside the mandrel. During the movement of the piston plate 31, the air inside the mandrel is blown to the surface of the needle strip to be assembled through the airflow via the air hole 33, instantly removing the dust attached to the surface of the needle strip.

[0069] Example 2:

[0070] Reference Figures 1-8 In this embodiment, the rubber sleeve 32 does not have air holes 33, but only a threaded structure on the inner wall. A guide frame 42 is fixedly connected to the top of the transition platform 6 to guide the cut needle strip into the connector. In the guide cavity of the guide frame 42, a first floating groove 43 with a gradually rising direction of movement is opened below it. Multiple sets of buoyancy tubes 45 are arranged at equal intervals in the first floating groove 43. Each buoyancy tube 45 is connected through a diverter tube 44, which is connected to the piston rod 30. When the piston plate 31 compresses the rubber... When the gas inside the sleeve 32 is being pumped out, it passes through the diversion pipe 44 and is blown out through the buoyancy pipe 45, thus keeping the stepped pin pack material in a suspended state. This ensures the transition between the two conveyor tables and the precise insertion into the connector holes. Furthermore, a second floating groove 46 with an arc-shaped structure is provided at the top of the cavity of the guide frame 42, which can guide the escaping airflow from the top to blow onto the pin pack material, preventing the pin pack material from tilting too high. This method not only ensures that the pin pack material is precisely stretched and cut, but also ensures more accurate subsequent assembly.

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

[0072] Step 1: Convey the needle-pack material and the connecting seat separately;

[0073] Step 2: After the needle-pack material is conveyed to the assembly station, it is tensioned and then cut;

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

[0075] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
