Abstract
Description
Technical Field
[0001] This utility model relates to the field of screw-in devices, and in particular to a screw-in device for loading wires into a screw-in connector. Background Technology
[0002] As a key frequency selection device, filters are used in modern electronic systems to selectively pass specific frequency signals and suppress irrelevant frequency bands. To ensure a reliable electrical connection between the filter and external wires, standardized screw holes are usually pre-made on both sides of the filter housing. In the production process, wire connectors need to be screwed into these screw holes of the filter housing by screwing in the screw head of the screw-in device to form the interface for wire insertion.
[0003] The screw-in head is currently moved by multiple motors, which are controlled by the PLC input port. However, at the moment the screw-in head is about to contact the hole, even if the PLC has been precisely positioned beforehand, changes occur during this brief calculation and control delay due to slight vibrations of the equipment itself and micro-expansion caused by temperature. This results in a radial deviation of 20-30 micrometers between the wire connector and the screw hole. Due to the existence of the radial deviation, the guide connector cannot be screwed into the screw hole, causing inconvenience in processing. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a screw-in device for screw-in connectors for loading wires, aiming to solve the technical problem that the radial deviation of 20-30 micrometers between the wire connector and the screw hole causes the guide connector to be unable to be screwed into the screw hole.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:
[0006] A screw-in device for loading screw-in connectors for wires includes a worktable. The top of the worktable is provided with a clamping mechanism for holding a filter housing, and a feeding mechanism for conveying the screw-in connector. The top of the worktable is also provided with a moving mechanism, and one side of the moving mechanism has a screw-in portion. The screw-in portion includes a connecting seat located on one side of the moving mechanism. A screw-in seat is rotatably connected to one side of the connecting seat. The screw-in seat has a movable cavity inside, and a mounting cylinder is located inside the movable cavity. One end of the mounting cylinder has a screw... The screw-in head protrudes from the outside of the movable cavity. A sliding convex ring is formed on the outside of the mounting cylinder. The outer diameter of the sliding convex ring matches the inner diameter of the movable cavity. The sliding convex ring slides into the movable cavity. The outer edge of the mounting cylinder is separated from the movable cavity to form a movable gap. A swing ring groove is formed inside the movable cavity. The swing ring groove is far away from the screw-in head. The inner diameter of the swing ring groove is larger than the inner diameter of the movable cavity, so that when the sliding convex ring slides into the swing ring groove, the sliding convex ring and the swing ring groove move into each other.
[0007] When the feeding mechanism delivers the screw-in connector to the screw-in head, the screw-in head loads the connector, causing it to be inserted into the screw hole of the filter housing by the moving mechanism. If there is a 20-30 micrometer positional deviation between the screw hole and the screw-in connector, the end of the screw-in connector cannot be precisely aligned with the center point of the screw hole inlet during the advancement process. The screw-in end of the connector will first contact the edge or side of the screw hole inlet. This contact generates a lateral force acting on the screw-in connector. As the screw-in connector advances, this lateral thrust is transmitted back to the mounting cylinder along the connector, thereby causing the sliding convex ring of the mounting cylinder to slide along the movable cavity. When the sliding ring is inserted into the oscillating ring groove, because the inner diameter of the oscillating ring groove is larger than the inner diameter of the movable cavity, the sliding convex ring loses its tight constraint with the inside of the movable cavity. The sliding convex ring moves with the oscillating ring groove, and because the outer edge of the mounting cylinder is separated from the movable cavity to form a movable gap, it provides a continuous guiding effect on the screw-in connector that has already contacted the edge of the screw hole. This allows the mounting cylinder to swing slightly along the movable gap. Under the guidance of the thread engagement force of the screw hole, the screw-in connector is smoothly pulled into the center of the screw hole, so that the axial screwing action of the screw-in connector can be carried out smoothly, completing a precise and reliable screw-in assembly. This eliminates the problem of screw-in connector assembly failure caused by radial deviation of 20-30 micrometers.
[0008] Furthermore, in this application, the connecting seat has a guide cylinder inside, and a rotating shaft is rotatably connected inside the guide cylinder. One end of the rotating shaft is provided with a connecting plate, which is connected to one side of the screw-in seat. The other end of the mounting cylinder is provided with a return spring, which is located inside the movable cavity. The movable cavity passes through one side of the screw-in seat, and one end of the return spring passes through the movable cavity, so that one end of the return spring is connected to the connecting plate.
[0009] When the screw-in head rotates, a guide cylinder is fixed inside the connector. Its core function is to provide precise axial support and a rotation track for the rotating shaft, thereby ensuring that the axis position of the screw-in head is strictly constrained and that there is no power deviation. When the screw-in head contacts the screw hole and produces a radial deviation (≤30μm), the thrust pushes the mounting cylinder, causing its external sliding convex ring to slide in the movable cavity, and the return spring thus contracts and stores energy. After the screw-in head screws the screw-in connector into the screw hole and leaves, the screw-in head is released from the contact force after the screwing is completed. The return spring extends and pushes the mounting cylinder back to its original position, and the sliding convex ring disengages from the swing ring groove, thereby facilitating the continuous screwing operation of the screw-in head.
[0010] Furthermore, in this application, the mounting cylinder has an internal mounting cavity, and the mounting cavity has a pneumatic finger. One end of the screw-in head has a limiting groove, which matches the shape of the screw-in connector. The limiting groove communicates with the mounting cavity. One end of the pneumatic finger has two finger-clamping ends, which are located inside the limiting groove. The pneumatic finger drives the two finger-clamping ends to open and close, so that the two finger-clamping ends abut against both sides of the mounting inner hole of the screw-in connector.
[0011] When the screw-in connector is inserted into the limiting groove, the pneumatic finger is activated to open the two clamping fingers, causing them to spread out and contact the two sides of the mounting inner hole of the screw-in connector. At the same time, because the shape of the limiting groove matches that of the screw-in connector, the screw-in connector is limited within the limiting groove, ensuring that the screw-in connector will not come out of the limiting groove when screwed into the screw hole.
[0012] Furthermore, in this application, guide grooves are provided on both sides of the mounting cylinder, and guide grooves communicating with the movable cavity are provided on both sides of the screw-in seat. A guide protrusion passes through the guide groove, so that the guide protrusion slides in cooperation with the adjacent guide groove. One end of the guide protrusion is spaced from the interior of the adjacent guide groove.
[0013] Furthermore, in this application, the moving mechanism includes a support frame disposed on the top of the workbench. A first moving frame is horizontally disposed on the top of the support frame. A first moving screw is rotatably connected inside the first moving frame. A first moving motor that drives the first moving screw to rotate is disposed inside the first moving frame. A first moving nut is sleeved on the outside of the first moving screw. A second moving frame is vertically disposed on one side of the first moving nut. A second moving screw is rotatably connected inside the second moving frame. A second moving motor that drives the second moving screw to rotate is disposed inside the second moving frame. A second moving nut is sleeved on the outside of the second moving screw. The connecting seat is disposed on one side of the second moving nut.
[0014] Furthermore, in this application, a lifting seat is provided on one side of the second movable nut, a supporting base plate is provided at the bottom of the lifting seat, a first rotating frame is rotatably connected to the bottom of the supporting base plate, a rotating motor is provided at the top of the supporting base plate, the rotating motor drives the first rotating frame to rotate, and the connecting seat is provided at the bottom of the first rotating frame.
[0015] Furthermore, in this application, a second rotating frame is rotatably connected to the bottom of the first rotating frame, a transmission motor is provided inside the first rotating frame, the transmission motor drives the second rotating frame to rotate, the connecting seat is provided on one side of the second rotating frame, and a screw-in motor is provided on the other side of the second rotating frame, the screw-in motor drives the rotating shaft to rotate.
[0016] Furthermore, in this application, the shaft end of the drive motor is provided with a first drive wheel, one side of the second rotating frame is provided with a second drive wheel, and a drive belt is sleeved on the outside of the first drive wheel and the second drive wheel.
[0017] Furthermore, in this application, the clamping mechanism includes a mounting base frame disposed on the top of the workbench, a mounting plate disposed on the top of the mounting base frame, a clamping plate disposed on the top of the mounting plate, a plurality of clamping cylinders disposed on the top of the clamping plate, a clamping block disposed at the piston rod end of the clamping cylinder, a clamping pressure block disposed at the bottom of the clamping block, and the clamping pressure block and the clamping plate being separated to form a clamping interval.
[0018] Furthermore, in this application, a rotating disk is rotatably connected to the top of the mounting plate, the clamping plate is disposed on the top of the rotating disk, the adjusting motor is disposed at the bottom of the mounting plate, and the adjusting motor drives the rotating disk to rotate.
[0019] This utility model has the following beneficial effects:
[0020] When the feeding mechanism delivers the screw-in connector to the screw-in head, the screw-in head loads the connector, causing it to be inserted into the screw hole of the filter housing by the moving mechanism. If there is a 20-30 micrometer positional deviation between the screw hole and the screw-in connector, the end of the screw-in connector cannot be precisely aligned with the center point of the screw hole inlet during the advancement process. The screw-in end of the connector will first contact the edge or side of the screw hole inlet. This contact generates a lateral force acting on the screw-in connector. As the screw-in connector advances, this lateral thrust is transmitted back to the mounting cylinder along the connector, thereby causing the sliding convex ring of the mounting cylinder to slide along the movable cavity. When the sliding ring is inserted into the oscillating ring groove, because the inner diameter of the oscillating ring groove is larger than the inner diameter of the movable cavity, the sliding convex ring loses its tight constraint with the inside of the movable cavity. The sliding convex ring moves with the oscillating ring groove, and because the outer edge of the mounting cylinder is separated from the movable cavity to form a movable gap, it provides a continuous guiding effect on the screw-in connector that has already contacted the edge of the screw hole. This allows the mounting cylinder to swing slightly along the movable gap. Under the guidance of the thread engagement force of the screw hole, the screw-in connector is smoothly pulled into the center of the screw hole, so that the axial screwing action of the screw-in connector can be carried out smoothly, completing a precise and reliable screw-in assembly. This eliminates the problem of screw-in connector assembly failure caused by radial deviation of 20-30 micrometers. Attached Figure Description

[0042] Reference Figures 1-16In some specific embodiments, a screw-in device for loading screw-in connectors for wires includes a worktable 100. The top of the worktable 100 is provided with a clamping mechanism 300 for clamping a filter housing 130. The top of the worktable 100 is also provided with a feeding mechanism 200 for conveying screw-in connectors 110. A moving mechanism 400 is located on the top of the worktable 100. A screw-in portion 500 is provided on one side of the moving mechanism 400. The screw-in portion 500 includes a connecting seat 516 located on one side of the moving mechanism 400. A screw-in seat 510 is rotatably connected to one side of the connecting seat 516. A movable cavity 512 is formed inside the screw-in seat 510, and a mounting cylinder 520 is located inside the movable cavity 512. One end of the mounting cylinder 520 is provided with a screw-in head 521, which protrudes from the outside of the movable cavity 512. The outer side of the mounting cylinder 520 is formed with a sliding protrusion ring 526, the outer diameter of which matches the inner diameter of the movable cavity 512. The sliding protrusion ring 526 and the movable cavity 512 are in sliding fit. The outer edge of the mounting cylinder 520 and the movable cavity 512 are separated to form a movable gap 5121. The movable cavity 512 is provided with a swing ring groove 513, which is far away from the screw-in head 521. The inner diameter of the swing ring groove 513 is larger than the inner diameter of the movable cavity 512, so that when the sliding protrusion ring 526 slides into the swing ring groove 513, the sliding protrusion ring 526 and the swing ring groove 513 are in movable fit.
[0043] Through the above technical solution, when the feeding mechanism 200 conveys the screw-in connector 110 to the screw-in head 521, the screw-in head 521 loads the screw-in connector 110, so that the screw-in head 521 loaded with the screw-in connector 110 is inserted into the screw hole of the filter housing 130 under the drive of the moving mechanism 400. If there is a positional deviation of 20-30 micrometers between the screw hole and the screw-in connector 110, the end of the screw-in connector 110 cannot be accurately aligned with the center point of the screw hole inlet during the advancement process. The screw-in end of the screw-in connector 110 will first contact the edge or side of the screw hole inlet. This contact generates a lateral force acting on the screw-in connector 110. As the screw-in connector 110 is advanced, this lateral thrust will be transmitted back to the mounting cylinder 520 along the screw-in connector 110, thereby driving the sliding convex ring 526 of the mounting cylinder 520 to slide along the movable cavity 512. When the sliding convex ring 526 slides into the swing ring groove 513, since the inner diameter of the swing ring groove 513 is larger than the inner diameter of the movable cavity 512, the sliding convex ring 526 loses its tight constraint with the inside of the movable cavity 512. The sliding convex ring 526 moves with the swing ring groove 513, and since the outer edge of the mounting cylinder 520 is separated from the movable cavity 512 to form a movable interval 5121, it has a continuous guiding effect on the screw-in connector 110 that has already contacted the edge of the screw hole, allowing the mounting cylinder 520 to swing slightly along the movable interval 5121. Under the guidance of the thread engagement force of the screw hole, the screw-in connector 110 is smoothly pulled into the center of the screw hole, so that the axial screw-in action of the screw-in connector 110 can be carried out smoothly, completing the precise and reliable screw-in assembly, thereby eliminating the problem of screw-in connector 110 assembly failure caused by radial deviation of 20-30 micrometers.
[0044] It should be noted that if the deviation between the screw hole and the screw-in connector 110 is greater than 30 micrometers, although the lateral force generated by the screw-in connector 110 contacting the edge of the screw hole will push the mounting cylinder 520 and the sliding convex ring 526 to perform radial translation within the movable cavity 512, when the sliding convex ring 526 slides to the swing ring groove 513, the small radial translation stroke allowed by the swing ring groove 513 will be quickly exhausted. At this time, due to the insufficient swing amplitude of the mounting cylinder 520, the screw-in connector 110 cannot be screwed into the screw hole. Even if a larger swing ring groove 513 is provided, if the swing angle of the mounting cylinder 520 is too large, it will cause the screw-in connector 110 to tilt and screw into the screw hole, resulting in the screw-in connector 110 not being centered after screwing in, which seriously affects subsequent use. Therefore, the above technical solution can only be used when the deviation between the screw hole and the screw-in connector is 20-30 micrometers.
[0045] Reference Figures 6-13In some specific embodiments, a guide cylinder 515 is provided inside the connecting seat 516, and a rotating shaft 511 is rotatably connected inside the guide cylinder 515. One end of the rotating shaft 511 is provided with a connecting plate 517, which is connected to one side of the screw-in seat 510. The other end of the mounting cylinder 520 is provided with a return spring 540, which is located inside the movable cavity 512. The movable cavity 512 passes through one side of the screw-in seat 510, and one end of the return spring 540 passes through the movable cavity 512, so that one end of the return spring 540 is connected to the connecting plate 517.
[0046] Through the above technical solution, when the screw-in head 521 rotates, the guide cylinder 515 is fixed inside the connecting seat 516. Its core function is to provide precise axial support and rotation track for the rotating shaft 511, thereby ensuring that the axial position of the screw-in head 521 is strictly constrained and that there is no deviation in power. When the screw-in head 521 contacts the screw hole and produces a radial deviation (≤30μm), the thrust pushes the mounting cylinder 520, causing the sliding convex ring 526 on its outside to slide in the movable cavity 512. The return spring 540 thus contracts and stores energy. After the screw-in head 521 screws the screw-in connector 110 into the screw hole and leaves, the screw-in head 521 is released from the contact force after the screwing is completed. The return spring 540 extends and pushes the mounting cylinder 520 back to its original position. The sliding convex ring 526 disengages from the swing ring groove 513, so that the screw-in head 521 can continue to perform screwing work.
[0047] Reference Figures 1-13 In some specific embodiments, the mounting cylinder 520 has an mounting cavity 527 inside, and a pneumatic finger 522 is provided inside the mounting cavity 527. One end of the screw-in head 521 has a limiting groove 524, which matches the shape of the screw-in connector 110. The limiting groove 524 is connected to the mounting cavity 527. One end of the pneumatic finger 522 has two finger-clamping ends 523, which are located inside the limiting groove 524. The pneumatic finger 522 drives the two finger-clamping ends 523 to open and close, so that the two finger-clamping ends 523 abut against both sides of the mounting inner hole 120 of the screw-in connector 110.
[0048] With the above technical solution, when the screw-in connector 110 is inserted into the limiting groove 524, the pneumatic finger 522 is activated to drive the two clamping finger ends 523 to unfold (the pneumatic finger 522 is existing technology and will not be discussed in detail). This causes the two clamping finger ends 523 to unfold and abut against both sides of the mounting inner hole 120 of the screw-in connector 110. At the same time, since the shape of the limiting groove 524 matches that of the screw-in connector 110, the screw-in connector 110 is limited within the limiting groove 524, ensuring that the screw-in connector 110 will not come out of the limiting groove 524 when it is screwed into the screw hole.
[0049] Reference Figures 6-8In some specific embodiments, guide grooves 531 are provided on both sides of the mounting cylinder 520, and guide setting grooves 530 communicating with the movable cavity 512 are provided on both sides of the screw-in seat 510. A guide sliding protrusion 532 is provided inside the guide setting groove 530, so that the guide sliding protrusion 532 slides and engages with the adjacent guide groove 531. One end of the guide sliding protrusion 532 is spaced from the interior of the adjacent guide groove 531.
[0050] With the above technical solution, when the mounting cylinder 520 is displaced in the movable cavity 512 due to radial deviation, the guide slide 532 slides with the adjacent guide slide groove 531, thereby facilitating the guidance of the sliding direction of the mounting cylinder 520. In order to facilitate the swinging of the mounting cylinder 520, there is a gap between the guide slide 532 and the adjacent guide slide groove 531, so that the guide slide 532 can make the mounting cylinder 520 swing while the guide slide groove 531 slides.
[0051] Reference Figures 1-4 In some specific embodiments, the moving mechanism 400 includes a support frame 410 disposed on the top of the workbench 100. A first moving frame 420 is horizontally disposed on the top of the support frame 410. A first moving screw 421 is rotatably connected inside the first moving frame 420. A first moving motor 422 is disposed inside the first moving frame 420 to drive the first moving screw 421 to rotate. A first moving nut 423 is sleeved on the outside of the first moving screw 421. A second moving frame 430 is vertically disposed on one side of the first moving nut 423. A second moving screw 431 is rotatably connected inside the second moving frame 430. A second moving motor 432 is disposed inside the second moving frame 430 to drive the second moving screw 431 to rotate. A second moving nut 433 is sleeved on the outside of the second moving screw 431. A connecting seat 516 is disposed on one side of the second moving nut 433.
[0052] With the above technical solution, when there are multiple screw holes to be screwed in at different heights, the first moving motor 422 drives the first moving screw 421 to rotate, thereby causing the first moving nut 423 to move laterally, which in turn causes the second moving frame 430 to adjust its lateral position so that the screw-in head 521 can move laterally to the corresponding screw hole; the second moving motor 432 drives the second moving screw 431 to rotate, thereby causing the second moving nut 433 to move vertically, which in turn causes the connecting seat 516 to adjust its vertical position so that the screw-in head 521 can move vertically to the corresponding screw hole, thus adapting to screw holes of different heights.
[0053] It should be noted that the first moving nut 423 moves in the width direction of the worktable 100, and the second moving nut 433 moves in the height direction of the worktable 100.
[0054] Reference Figures 1-4 In some specific embodiments, a lifting seat 434 is provided on one side of the second movable nut 433, a support base plate 440 is provided at the bottom of the lifting seat 434, a first rotating frame 441 is rotatably connected to the bottom of the support base plate 440, a rotating motor 442 is provided at the top of the support base plate 440, the rotating motor 442 drives the first rotating frame 441 to rotate, and a connecting seat 516 is provided at the bottom of the first rotating frame 441.
[0055] With the above technical solution, when the screw hole to be screwed in is located on a different side of the filter housing 130, the rotating motor 442 drives the first rotating frame 441 to rotate, so that the screw head 521 can rotate to the corresponding side of the filter housing 130, so as to screw in the screw-in connector 110 on that side.
[0056] Reference Figures 1-4 In some specific embodiments, a second rotating frame 450 is rotatably connected to the bottom of the first rotating frame 441. A drive motor 443 is provided inside the first rotating frame 441, which drives the second rotating frame 450 to rotate. A connecting seat 516 is provided on one side of the second rotating frame 450, and a screw-in motor 514 is provided on the other side of the second rotating frame 450, which drives the rotating shaft 511 to rotate.
[0057] With the above technical solution, when the screw hole to be screwed in is located on the top surface of the filter housing 130, the drive motor 443 drives the second rotating frame 450 to rotate, so that the screw-in head 521 can rotate to the top surface of the filter housing 130, so as to screw in the screw-in connector 110 to the top surface.
[0058] It should be noted that the rotation axis of the first rotating frame 441 is perpendicular to the length direction of the worktable 100, and the rotation axis of the second rotating frame 450 is parallel to the width direction of the worktable 100.

[0062] With the above technical solution, when the filter housing 130 is placed in the clamping interval 333, the clamping cylinder 330 drives the clamping block 331 to move downward. The clamping block 331 drives the clamping pressure block 332 to abut against the filter housing 130, so that the clamping block 331 and the clamping plate 321 clamp the filter housing, thereby preventing the filter housing 130 from being displaced when it is screwed into the screw-in connector 110.
[0063] Reference Figures 14-16 In some specific embodiments, a rotating disk 320 is rotatably connected to the top of the mounting plate 311, a clamping plate 321 is disposed on the top of the rotating disk 320, and an adjusting motor 312 is disposed at the bottom of the mounting plate 311, the adjusting motor 312 drives the rotating disk 320 to rotate.
[0064] With the above technical solution, when each side of the filter housing 130 has a screw hole, the adjusting motor 312 drives the rotating disk 320 to rotate, so that the side of the filter housing 130 to be processed is aligned with the screw head 521, so that the screw head 521 can screw the screw-in connector 110 into the screw hole on the side.
