Description

Technical Field

[0001] The present application relates to the field of connector processing, and in particular to a terminal plugging device. Background Art

[0002] In modern industry, connectors are core components for achieving circuit or signal connections. They transmit information or current through the contact between male and female terminals. For example, automotive connectors are used in a car's electrical system to transmit current and signals between various components, ensuring driving safety and stable performance.

[0003] Currently, connectors primarily consist of a housing and terminals. During assembly, the terminals are sequentially secured to a continuous strip of material. The strip is then transported to a cutting mechanism where it is cut to separate the terminals from the strip. The separated terminals are then plugged into the housing. Using strips to secure and transport the terminals allows for efficient and orderly terminal supply, significantly improving production efficiency.

[0004] However, this terminal delivery method also has significant drawbacks in practical applications. Specifically, when cutting the strip, some metal powder is inevitably generated. This metal powder easily adheres to the terminal surface, preventing the terminal from accurately mating with the housing. This significantly reduces the assembly security between the terminal and the housing, making the connector prone to loose connections after assembly, leading to problems such as poor circuit contact and signal transmission interruption, reducing the safety and reliability of the connector.

[0047] The following is combined with Figure 1-8 The present invention is described in further detail.

[0048] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0049] See also Figure 1-8 FIG2 shows a terminal plugging device, which includes a first bracket 7 and a second bracket 8. The first bracket 7 is provided with a first feeding mechanism 1, a cutting mechanism 3, and a plugging mechanism 4. The second bracket 8 is provided with a second feeding mechanism 2. A plurality of terminals are fixed on a material strip 100 at intervals. The first feeding mechanism 1 is used to convey the material strip 100, the second feeding mechanism 2 is used to convey a housing 101, the cutting mechanism 3 is used to cut the material strip 100, and the plugging mechanism 4 is used to plug the terminals into the housing 101.

[0050] In this embodiment, the conveying directions of the first feeding mechanism 1 and the second feeding mechanism 2 are parallel to each other, the first feeding mechanism 1 has a cutting station at the end of its feeding stroke, and the second feeding mechanism 2 has a splicing station at the end of its feeding stroke. The cutting station and the splicing station are arranged adjacent to each other, the cutting mechanism 3 is located at the cutting station and is provided with a blowing assembly 5, and the splicing mechanism 4 is located on the side of the cutting mechanism 3 away from the splicing station.

[0051] During plugging, the first feeding mechanism 1 conveys the material strip 100 to the cutting station, and the cutting mechanism 3 cuts the material strip 100. During cutting, the blowing component 5 can blow away the generated metal powder to prevent excessive metal powder from adhering to the terminal, thereby improving the plugging accuracy between the terminal and the shell 101; while the first feeding mechanism 1 conveys the material strip 100, the second feeding mechanism 2 conveys multiple shells 101 to the plugging station in turn, and then the plugging mechanism 4 plugs the cut terminals with the shells 101 of the plugging station relative to each other and assembles them into a connector; a belt conveyor is also connected to the end of the second feeding mechanism 2, and the plugged connector is output to the outside through the belt conveyor.

[0052] In this embodiment, combined with Figure 1-2 As shown, the terminal plugging device also includes a flattening mechanism 6, located on the side of the cutting station away from the first feeding mechanism 1. The flattening mechanism 6 comprises a third bracket 6c connected to the cutting mechanism 3, a flattening plate 6a mounted on the third bracket 6c and movable toward or away from the cutting station, and a first drive module 6b for driving the flattening plate 6a. The first drive module 6b is a pneumatic cylinder. The height of the flattening plate 6a is greater than the conveying height of the material strip 100. The flattening plate 6a has a flattening stroke opposite to the feeding direction of the first feeding mechanism 1, and a return stroke in the same direction as the feeding direction of the first feeding mechanism 1.

[0053] Since the material strip 100 is long and flexible, it is prone to bending during transportation. This bending of the material strip 100 will change the position of the terminals. Based on this, the present application provides a flattening mechanism 6. When the material strip 100 is output to the cutting station, the flattening plate 6a can move in the opposite direction of the material strip 100 and squeeze the upper side of the material strip 100 during the movement to flatten the bending of the material strip 100 during transportation, so that the terminals can be accurately docked with the housing 101. After the material strip 100 is moved into place, the flattening plate 6a is reset in a direction away from the cutting station to prevent the flattening plate 6a from interfering with the cutting of the cutting mechanism 3.

[0054] In this embodiment, combined with Figure 2-4 As shown, the cutting mechanism 3 includes a fourth bracket 3a upright mounted on one end of the first bracket 7 near the second loading mechanism 2, a liftable upper cutting seat 3b mounted on the upper end of the fourth bracket 3a, multiple cutting knives 3d mounted on the bottom of the upper cutting seat 3b, a seventh drive module 3k for driving the upper cutting seat 3b upward and downward, a liftable lower cutting seat 3c mounted on the lower end of the fourth bracket 3a, and a knife groove 3e defined at the top of the lower cutting seat 3c. The cutting station is located between the upper and lower cutting seats 3b, 3c. The seventh drive module 3k is a cylinder, and the upper cutting seat 3b is mounted on the piston rod of the cylinder.

[0055] When the strip 100 reaches the cutting station, the lower cutting seat 3c rises to carry the strip 100. The flattening plate 6a reaches above the lower cutting seat 3c and flattens the strip 100. The upper cutting seat 3b then descends and approaches the lower cutting seat 3c. The cutter 3d cooperates with the knife groove 3e to quickly cut the strip 100, effectively improving cutting accuracy and efficiency. As the cutter 3d cuts the strip 100, the air blowing assembly 5 blows the cut strip 100 and the generated metal powder directly into the knife groove 3e, facilitating subsequent cleaning of the strip 100 and the powder.

[0056] In this embodiment, combined with Figure 3-4 As shown, the bottom of the upper cutting seat 3b is provided with a mounting groove 3f, in which a binder block 3g is embedded. A plurality of cutters 3d are spaced apart at the bottom of the binder block 3g. The blowing assembly 5 includes an air inlet pipe 5a connected to the upper cutting seat 3b and communicating with the mounting groove 3f, and two air blowing channels 5b extending through the binder block 3g. The two air blowing channels 5b extend from the mounting groove 3f to the cutters 3d. The upper ends of the air blowing channels 5b communicate with the mounting groove 3f, and the lower ends form air outlets 5c. The two air outlets 5c are respectively located between two adjacent groups of cutters 3d. The air blowing pipe is connected to an external air source and is used to blow air into the mounting groove 3f. Compressed air is blown through the two air blowing channels 5b toward the space between the two adjacent groups of cutters 3d, thereby purging metal powder while the cutters 3d cut the material strip 100, effectively improving the cleaning effect of the metal powder.

[0057] In this embodiment, the multiple cutters 3d include a first cutter body 3d1 and multiple second cutter bodies 3d2. The first cutter body 3d1 is arranged close to the first loading mechanism 1, and is used to cut the material strip 100 input to the cutting station as a whole. The multiple second cutter bodies 3d2 are located on the side of the first cutter body 3d1 away from the first loading mechanism 1, and are used to cut several terminals on the material strip 100.

[0058] A plurality of first card slots 31 are provided at the bottom of the pressing block 3g. The arrangement direction of the plurality of first card slots 31 is perpendicular to the conveying direction of the first feeding mechanism 1. The first card slots 31 are used to press the terminal against the lower cutting seat 3c after the cutter 3d cuts the material strip 100 to prevent the terminal from falling.

[0059] In this embodiment, the lower cutting seat 3c is hollow, and its lower end is connected to a collection tube 3m. The collection tube 3m is connected to an air intake pipe 3n, which is connected to an external air source. When the cutter 3d cuts the material strip 100, the air intake pipe 3n cooperates with the air inlet pipe 5a to draw the cut material strip 100 and metal powder into the collection tube 3m.

[0060] In this embodiment, again combined Figure 2As shown, the cutting mechanism 3 also includes a horizontally movable transmission assembly 3h located below the first bracket 7, and a second drive module 3i for driving the transmission assembly 3h. The movement direction of the transmission assembly 3h is perpendicular to the conveying direction of the first loading mechanism 1. The second drive module 3i is a pneumatic cylinder. The transmission assembly 3h can be positioned to the side of the lower cutting seat 3c and drives the lower cutting seat 3c up and down during its translational travel, leaving sufficient space below the lower cutting seat 3c for accommodating the collection drum 3m.

[0061] Specifically, the transmission assembly 3h comprises a transmission block 3h1 and two transmission plates 3h2, one located on either side of the end of the transmission block 3h1 near the insertion station. Both transmission plates 3h2 are arranged upright and perpendicular to the direction of movement of the transmission assembly 3h. Each transmission plate 3h2 defines a first transmission slot 3h3, which curves downward toward the insertion station. The cutting mechanism 3 also comprises a mating assembly 3j, which comprises a mating block 3j1 connected to the lower end of the lower cutting seat 3c and two mating rods 3j2, one located on either side of the lower end of the mating block 3j1. The two mating rods 3j2 are slidably inserted into the two first transmission slots 3h3.

[0062] The two transmission plates 3h2 are supported on the bottom of the lower cutting seat 3c through the first transmission groove 3h3. When the transmission block 3h1 moves toward the direction close to the plug-in station, the matching rod 3j2 gradually moves upward in the first transmission groove 3h3 and drives the lower cutting seat 3c to rise; when the transmission block 3h1 moves toward the direction away from the plug-in station, the matching rod 3j2 gradually moves downward in the first transmission groove 3h3 and drives the lower cutting seat 3c to descend.

[0063] A first sensor 3o is further provided on one side of the upper cutting seat 3b close to the first feeding mechanism 1. The first sensor 3o is a proximity sensor, which is used to detect whether the material strip 100 is in place. Only when it is in place can the cutting mechanism 3 cut the material strip 100.

[0064] In this embodiment, combined with Figure 5As shown, the plug-in mechanism 4 includes a plug-in seat 4a disposed on the upper portion of the first bracket 7 and movable in the direction from the cutting station to the plug-in station, a third drive module 4b for driving the plug-in seat 4a to move, and a clamping assembly 4c disposed on the plug-in seat 4a. The clamping assembly 4c includes two clamping plates 4c1 arranged vertically, the two clamping plates 4c1 being respectively movable, and a plurality of second clamping grooves 4c2 for relative engagement with the terminals are also defined on the inner front ends of the two clamping plates 4c1. The third drive module 4b is a pneumatic cylinder. The fourth bracket 3a is disposed between the first bracket 7 and the cutting station and is provided with a first opening 3p for the clamping assembly 4c to pass through. The two clamping plates 4c1 are respectively driven to move upward and downward by a ninth drive module 4c3 to clamp the terminals and relative engage the terminals with the housing 101 during the movement of the plug-in seat 4a. The ninth drive module 4c3 is a pneumatic cylinder.

[0065] In this embodiment, combined with Figure 6 As shown, the first feeding mechanism 1 includes a first feeding seat 1a disposed on the upper portion of the first bracket 7, a first feeding trough 1b provided on the first feeding seat 1a, a first material moving rack 1c that can be raised and lowered and translated along the extension direction of the first feeding trough 1b, and a fourth driving module 1d for driving the movement of the first material moving rack 1c. The first material moving rack 1c is located above the first feeding trough 1b, and two first material moving rods 1g are further provided at the bottom of the first material moving rack 1c. The fourth driving module 1d is composed of two cylinders for driving the translation and raising and lowering of the first material moving rack 1c, respectively.

[0066] When conveying the material belt 100, the first material moving rack 1c descends, and the two first material moving rods 1g are inserted into the material belt 100, and then the first material moving rack 1c moves forward along the extension direction of the first loading trough 1b, and the first material moving rod 1g drives the material belt 100 to move forward; after the material belt 100 moves into place, the first material moving rack 1c rises, and the two first material moving rods 1g are separated from the material belt 100, and then the first material moving rack 1c resets backward. After the cutting of the material belt 100 at the cutting station is completed, the first material moving rack 1c descends again and the two first material moving rods 1g are inserted into the material belt 100, and then the first material moving rack 1c moves forward again, thereby realizing continuous conveying of the material belt 100.

[0067] In this embodiment, the first loading chute 1b is covered with a cover plate 1e, which defines a slot 1f extending along the length of the first loading chute 1b. A first material transfer rod 1g is slidably inserted into the slot 1f. The cover plate 1e acts as a barrier against the material strip 100, preventing it from tilting upward during transport. Furthermore, the slot 1f limits the travel of the first material transfer rack 1c, ensuring that the length of the material strip 100 that can be transferred in a single pass matches the number of terminals to be connected. The specific length of the slot 1f can be flexibly adjusted based on the connector specifications.

[0068] The cover plate 1e also has a limit opening 1h, into which a limit block 1i is inserted. This contact contacts the upper portion of the material strip 100 to limit the position of the material strip 100 and prevent it from shifting during transport. A second sensor 1j is also located at the front end of the cover plate 1e. This proximity sensor detects the position of the material strip 100, enabling the first transport rack 1c to accurately transport the material strip 100.

[0069] In this embodiment, a support seat 1k is further provided at the front end of the first loading mechanism 1. A pressure block 11 is provided on the support seat 1k. The front end of the material strip 100 is supported on the support seat 1k, and the pressure block 11 contacts the upper portion of the material strip 100. This prevents the front end of the material strip 100 from drooping downward during the loading process, thereby preventing the material strip 100 from shifting during transportation within the first loading mechanism 1.

[0070] In this embodiment, combined with Figure 7-8 As shown, the second bracket 8 includes a plurality of frames 8a arranged at intervals along the conveying direction of the second loading mechanism 2, the second loading mechanism 2 includes a second loading seat 2a supported on the upper ends of the plurality of frames 8a, a second loading trough 2b opened on the second loading seat 2a, a second transmission groove 2c opened through the bottom of the second loading trough 2b, a second moving rack 2d arranged to be slidable along the length direction of the second transmission groove 2c, and a fifth driving module 2e for driving the second moving rack 2d to move, the notch of the second loading trough 2b is arranged toward the first loading mechanism 1, the second moving rack 2d is located below the second transmission groove 2c and extends along the length direction of the second transmission groove 2c, the plurality of frames 8a are respectively provided with second openings 8b for the second moving rack 2d to pass through, and a plurality of second moving rods 2f are arranged at intervals along the moving direction of the second moving rack 2d, and the plurality of second moving rods 2f are slidably arranged in the second transmission groove 2c along the extension direction of the second transmission groove 2c, and the fifth driving module 2e is a cylinder.

[0071] When conveying the shell 101, multiple shells 101 are respectively accommodated in the second loading trough 2b, and multiple second moving rods 2f are respectively inserted into the second loading trough 2b through the second transmission groove 2c. The multiple second moving rods 2f are respectively in contact with the multiple shells 101. Then, during the movement of the second moving rack 2d, the multiple second moving rods 2f can move the multiple shells 101 forward in turn, effectively improving the loading efficiency and loading stability of the shell 101; at the same time, the notch of the second loading trough 2b is facing the first loading mechanism 1, so that the plug-in mechanism 4 can conveniently plug the terminal and the shell 101 relative to each other.

[0072] In this embodiment, the second loading seat 2a is provided with a positioning port 2g that communicates with the second loading trough 2b. The positioning port 2g is located at the plug-in station. The second loading mechanism 2 also includes a first positioning assembly 2h. The first positioning assembly 2h is located on the side of the second loading seat 2a away from the cutting station. The first positioning assembly 2h includes a fifth bracket 2h3, a first positioning block 2h1 that is movable along a direction toward or away from the positioning port 2g and is provided on the fifth bracket 2h3. A sixth drive module 2h2 is used to drive the movement of the first positioning block 2h1. The sixth drive module 2h2 is a cylinder. The movement direction of the first positioning block 2h1 is perpendicular to the conveying direction of the second loading mechanism 2. The first positioning block 2h1 can be inserted into the positioning port 2g during its movement. When the housing 101 reaches the plug-in station, the first positioning block 2h1 can extend into the positioning port 2g and plug relative to the housing 101 to position the housing 101 at the plug-in station. In this way, the plug-in mechanism 4 can accurately insert the terminal into the housing 101.

[0073] Below the first positioning assembly 2h is a second positioning assembly 2i. This assembly comprises a sixth bracket 2i1, a second positioning block 2i2 that is liftable and mounted on the bracket 2i1, a positioning slot 2i3 formed at the top of the second positioning block 2i2, and an eighth drive module 2i4 for driving the second positioning block 2i2 upward and downward. The eighth drive module 2i4 is a pneumatic cylinder. The second positioning block 2i2, located below the first positioning block 2h1, engages the piston rod of the sixth drive module 2h2 through the positioning slot 2i3 after the first positioning block 2h1 extends, preventing the first positioning block 2h1 from accidentally moving and affecting the terminal insertion process.
