Description

Technical Field

[0001] This invention belongs to the field of assembly equipment technology, and particularly relates to a connector terminal insertion device. Background Technology

[0002] Connector terminal insertion equipment is essentially an automated assembly device that precisely inserts the metal terminals (pins / holes) of connectors into plastic housings or circuit boards. Common names include "pin insertion machine", "terminal insertion machine", and "pin and socket insertion equipment".

[0003] Existing connector terminal insertion equipment uses tubular carrier tape to support metal terminals. Using truncated tubular carrier tape affects processing continuity, while using complete tubular carrier tape requires stretching to ensure accurate alignment between the terminal and the housing due to the long-term winding and storage of the tubular carrier tape. This stretching requires sufficient space and a large footprint. On the other hand, using tubular carrier tape with insufficient support can prevent elastic bending after unfolding, but its limited support means that the terminal will drop due to gravity after extension, which can easily lead to inaccurate positioning during output and insertion. Summary of the Invention

Detailed Implementation

[0018] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] This invention provides a connector terminal insertion device, such as... Figure 1-10 As shown, the connector terminal insertion device includes: a support frame 1; an adjustment frame 2 installed on the inner wall of the support frame 1, the adjustment frame 2 having a threaded rod 3 internally threaded and an adjustment block externally threaded onto the threaded rod 3; a guide rail 4 fixed on the adjustment block, the guide rail 4 having an adjustment mechanism 5 for adjusting the position of the tubular carrier tape of the terminal externally threaded, the adjustment mechanism 5 having a housing 9 externally threaded; a clamping and limiting structure provided on the housing 9 for clamping and stabilizing the tubular carrier tape, the clamping and limiting structure also being used to assist in terminal insertion; a test box 6 installed on the support frame 1 for testing the angle of the tubular carrier tape; and a limiting shell 7 fixed on the support frame 1 for accommodating the terminal shell, the limiting shell 7 having a guide frame 8 for providing a feeding channel for the terminal shell.

[0020] In this embodiment, after the equipment is started, the tubular carrier tape extends into the housing 9. According to the installation requirements of the terminal housing, after the material is loaded, the operator tests the unfolding angle of the tubular carrier tape in the test box 6. If there is a deviation in the angle, it is dealt with in time. If there is no deviation, the tubular carrier tape is clamped and stabilized by the clamping and limiting structure. The adjusting block is driven to move along the guide rail 4 by rotating the threaded rod 3, thereby driving the housing 9 and the overall adjusting mechanism 5 to adjust their positions in the horizontal direction, and completing the insertion of the output end of the tubular carrier tape into the terminal housing. By coordinating the clamping and limiting structure with the adjustment mechanism 5, the problems of bending caused by long-term winding of traditional complete tubular carrier tape and the need for large space for stretching after unfolding are solved. The support force provided by the clamping and limiting structure is sufficient to overcome the terminal drop caused by gravity, thereby improving the positioning accuracy during output and insertion. The threaded rod 3 connected by the internal thread of the adjustment frame 2, together with the guide rail 4, realizes the stepless position adjustment of the outer shell 9. The terminal shell feeding channel formed by the limiting shell 7 and the guide frame 8 realizes the directional conveying and rapid positioning of materials.

[0021] In a further preferred embodiment of the present invention, the adjusting mechanism 5 includes a first motor 10 fixed inside the housing 9, two movable wheels 11 rotatably mounted inside the housing 9 and extending outside the housing 9, the movable wheels 11 contacting the outer wall of the guide rail 4, a third rubber belt for transmission between the two movable wheels 11, a first rotating shaft 14, a second rotating shaft, and a third rotating shaft rotatably mounted inside the housing 9, a first bevel gear 12 fixed on the third rotating shaft and any one of the movable wheels 11, the two first bevel gears 12 meshing with each other, a first rubber belt 13 disposed between the second rotating shaft and the third rotating shaft, a connecting mechanism disposed between the first rotating shaft 14 and the second rotating shaft for adjusting the transmission connection state, a plurality of fourth rotating shafts rotatably mounted on the outer wall of the housing 9, a plurality of second rotating shafts fixed on each of the plurality of fourth rotating shafts, the plurality of second rotating shafts meshing in pairs for transmission, and a first gear 15 fixed on the first rotating shaft 14 and meshing with any one of the second gears, the clamping and limiting structures being grouped on any two adjacent fourth rotating shafts.

[0022] In this embodiment, after the first motor 10 is started, it drives two moving wheels 11 to roll on the outer wall of the guide rail 4, thereby driving the outer shell 9 to move along the guide rail 4 to adjust the output position of the tubular carrier belt. At the same time, the power of the first motor 10 is transmitted to the first rotating shaft 14 through the second rotating shaft, the third rotating shaft, the first bevel gear 12, the third rubber belt and the connecting mechanism (the path is first motor 10-moving wheel 11-first bevel gear 12-third rotating shaft-third rubber belt-second rotating shaft-connecting mechanism-first rotating shaft 14). The first rotating shaft 14 drives any one of the second gears to rotate through the first gear 15. Multiple second gears transmit power to each fourth rotating shaft in sequence through two-to-two meshing. Multiple clamping and limiting structures set in groups on adjacent fourth rotating shafts operate synchronously to perform multi-point clamping and limiting of the tubular carrier belt. By setting up a combined transmission of the first motor 10, the first bevel gear 12, the first rubber belt 13 and the moving wheel 11, not only is the smooth movement and positioning of the outer shell 9 on the guide rail 4 achieved, avoiding the problem of excessive floor space caused by the large space required for stretching the carrier belt in traditional equipment, but the closed state of the clamping and limiting structure can also be adjusted.

[0023] In a further preferred embodiment of the present invention, the clamping and limiting structure includes a connecting frame 16 fixed on the fourth rotating shaft, an abutment plate 17 fixed on the connecting frame 16, and a retaining sleeve 18 mounted on the abutment plate 17. Each of the two retaining sleeves 18 has a slot for accommodating the tubular carrier tape on one side close to each other. A pressure sensor is provided on the limiting shell 7. A contact plate is provided on the outer sleeve of the pressure sensor. The abutment plate 17 contacts the contact plate to limit the insertion depth of the terminal. A guide plate 19 for assisting in guiding and supporting the carrier tape is installed on either of the abutment plates 17.

[0024] In this embodiment, the fourth rotating shaft rotates under the drive of the adjusting mechanism 5, which drives the connecting frame 16 fixed on it to rotate synchronously. The abutment plate 17 on the connecting frame 16 moves to both sides of the tubular carrier tape. The clamping cylinder 18 on the abutment plate 17 accommodates the tubular carrier tape in the slot between the two clamping cylinders 18 in a relative posture, realizing the lateral clamping and limiting of the tubular carrier tape. When the terminal shell enters the limiting shell 7 through the guide frame 8 and completes the positioning, the metal terminal in the tubular carrier tape is output in a predetermined direction under the guidance of the clamping and limiting structure. The abutment plate 17 moves forward until the abutment plate 17 contacts the contact plate surface on the limiting shell 7. The contact plate feeds back the abutment force sensed by the pressure sensor to the control system. The control system determines that the terminal has reached the preset insertion depth and immediately stops the terminal output action, completing the insertion of a single terminal. By setting a slot on the clamping sleeve 18, a wrap-around clamping effect is formed on the tubular carrier tape, effectively eliminating the problem of gravity-induced sag caused by insufficient support force of the carrier tape. The terminal output trajectory remains stable at all times. The cooperation between the contact plate 17 and the contact plate on the limiting shell 7 constitutes a mechanical depth limiting mechanism. The pressure sensor is used to sense the contact force between the contact plate 17 and the contact plate in real time, changing the control of the terminal insertion depth from traditional stroke positioning to force feedback positioning, avoiding over-insertion or under-insertion caused by mechanical clearance or elastic deformation of the carrier tape.

[0025] In a further preferred embodiment of the present invention, the connecting mechanism includes a mounting bracket 31 fixed on the outer wall of the housing 9, a limiting block 25 fixed on the third rotating shaft, a transmission shaft rotatably mounted on the mounting bracket 31, a limiting cylinder 26 slidably sleeved on the transmission shaft, the limiting cylinder 26 being sleeved on the limiting block 25 for transmission, an electric telescopic rod 28 fixed on the housing 9, a connecting plate 29 fixed on the output rod of the electric telescopic rod 28, the connecting plate 29 being rotatably connected to the limiting cylinder 26, and a second rubber belt 27 disposed between the transmission shaft and the first rotating shaft 14 for transmission. A limiting rod 30 in contact with the outer wall of the limiting cylinder 26 is fixed on the mounting bracket 31.

[0026] In this embodiment, during power transmission, the second rotating shaft drives the limiting block 25 to rotate. When the connecting mechanism is in the transmission communication state, the electric telescopic rod 28 is in the retracted position, and the limiting cylinder 26 maintains the sleeve relationship with the limiting block 25. The second rotating shaft, in conjunction with the second rubber belt 27, transmits power to the first rotating shaft 14. When it is necessary to switch the transmission state, the electric telescopic rod 28 extends to push the connecting plate 29, causing the limiting cylinder 26 to slide along the transmission shaft axis and disengage from the sleeve range of the limiting block 25. The electric telescopic rod 28 drives the connecting plate 29 to push the limiting cylinder 26 to slide along the transmission shaft axially, thereby realizing the rapid switching of the transmission path between the first rotating shaft 14 and the third rotating shaft by disengaging from or engaging with the limiting block 25. When the limiting cylinder 26 disengages from the limiting block 25, the limiting rod 30 contacts the limiting cylinder 26 and applies continuous radial constraint to the outer wall of the limiting cylinder 26, stabilizing the clamping state after the power is disconnected.

[0027] In a further preferred embodiment of the present invention, a first cylinder 20 is fixed on the outer shell 9, and a cutting blade 21 for cutting the tubular carrier tape is installed on the output rod of the first cylinder 20. A second cylinder 22 is installed on the outer shell 9, and a clamping block 23 is fixed on the output rod of the second cylinder 22. The clamping block 23 cooperates with the outer shell 9 to clamp and stabilize the tubular carrier tape. A clamping opening for accommodating the tubular carrier tape is provided between the clamping block 23 and the outer shell 9.

[0028] In this embodiment, after the tubular carrier tape enters the housing 9 area, the second cylinder 22 drives the clamping block 23 to move towards the housing 9. The clamping opening between the clamping block 23 and the housing 9 gradually narrows, firmly clamping the tubular carrier tape between the two. The first cylinder 20 pushes the cutting blade 21 to extend along the direction of the tubular carrier tape, and the cutting blade 21 cuts off the tubular carrier tape segment. The first cylinder 20 drives the cutting blade 21 to cut the tubular carrier tape at a fixed point, so that each insertion consumes only a section of carrier tape. This avoids the problems of unfolding, bending and space occupation caused by the excessive length of the carrier tape when using a complete tubular carrier tape, and also avoids the processing interruption caused by the discontinuity of the interface of the cut carrier tape, thus realizing the continuity of carrier tape feeding. The second cylinder 22, together with the clamp formed by the outer shell 9, applies a controllable clamping force to the tubular carrier tape, which can provide lateral support to the carrier tape at the moment of terminal output.

[0029] In a further preferred embodiment of the present invention, an extension plate 24 for guiding the tubular carrier belt into the clamping opening is fixed on the clamping block 23 by a connecting rod. The distance between the extension plate 24 and the clamping block 23 is not less than 0.2 mm, and it is used to accommodate the cutting blade 21. Anti-slip pads for increasing the clamping contact friction are provided in both clamping openings.

[0030] In this embodiment, before the tubular carrier tape enters the clamping slot, it is first guided by the extension plate 24. The tubular carrier tape slides smoothly into the clamping slot between the clamping block 23 and the outer shell 9 along the guide surface formed by the extension plate 24. When the first cylinder 20 drives the cutting blade 21 to extend and cut the carrier tape, the cutting blade 21 passes through the gap between the extension plate 24 and the clamping block 23 and enters the clamping area to complete the cutting action. The extension plate 24 connects the feeding path of the tubular carrier belt with the clamping area of ​​the clamping block 23, so that the carrier belt completes the orientation correction before entering the clamping jaws, avoiding lateral offset and twisting caused by the unconstrained free end of the carrier belt. The gap between the extension plate 24 and the clamping block 23 is specially reserved for the movement channel of the cutting blade 21, so that the cutting action can be performed directly in the clamping state without first releasing the clamping before cutting. The anti-slip pads set in the clamping jaws increase the friction coefficient between the clamping block 23 and the tubular carrier belt, increasing the clamping stability.

[0031] In a further preferred embodiment of the present invention, the connecting frame 16 includes an outer cylinder 32 fixed on the fourth rotating shaft, a first spring 33 fixed inside the outer cylinder 32, and an inner rod 34 fixed on the first spring 33 and extending to the outside of the outer cylinder 32. The inner rod 34 is connected to the abutment plate 17. The first spring 33 is provided with a limiting telescopic rod for limiting the spring extension path.

[0032] In this embodiment, when the fourth rotating shaft rotates, it drives the outer cylinder 32 to rotate synchronously, so that the clamping tube 18 moves closer to the tubular carrier belt to complete the clamping. During the insertion of the terminal, the first spring 33 inside the outer cylinder 32 accumulates elastic potential energy on the inner rod 34. The abutment plate 17 abuts against the contact plate and retracts inward. The pressure sensor senses the abutment force through the contact plate and feeds it back to the control system to complete the depth determination. The elastic telescopic structure composed of the outer cylinder 32, the first spring 33 and the inner rod 34 enables the contact plate 17 to adapt to the pressure when it contacts the contact plate. The limiting telescopic rod constrains the telescopic path of the first spring 33, ensuring that the elastic restoring force always acts on the inner rod 34 along the axial direction.

[0033] In a further preferred embodiment of the present invention, a guide groove 35 is provided on the inner wall of the outer cylinder 32, and a guide block 36 is slidably installed in the guide groove 35. The guide block 36 is connected to the inner rod 34, and the guide groove 35 cooperates with the guide block 36 to limit the movement path of the inner rod 34.

[0034] In this embodiment, when the inner rod 34 extends and retracts towards the outer cylinder 32 under the elastic force of the first spring 33, the guide block 36 slides along the guide groove 35 on the inner wall of the outer cylinder 32. The guide groove 35 imposes a strict path constraint on the movement trajectory of the guide block 36, so that the inner rod 34 extends smoothly only along the axial direction defined by the guide groove 35, driving the contact plate 17 to advance synchronously. By setting up a sliding guide mechanism consisting of guide groove 35 and guide block 36, the inner rod 34 always moves along a single axis during the extension and retraction process, eliminating the radial swing and deflection of the inner rod 34 caused by elastic extension and retraction, and ensuring that the movement direction of the contact plate 17 is always consistent with the output direction of the tubular carrier belt.

[0035] In a further preferred embodiment of the present invention, the test box 6 is provided with a notch 37, and a camera 38 for capturing the terminal state of the tubular carrier tape is installed in the notch 37. The camera 38 is used to cooperate with an external visual analysis device to detect the angle of the tubular carrier tape.

[0036] In this embodiment, after the tubular carrier tape is output from the housing 9, it passes through the notch 37 area on the test box 6 along a predetermined path. The camera 38 installed in the notch 37 captures the arrangement of the terminals on the tubular carrier tape and the unfolding angle of the carrier tape in real time as the carrier tape passes through. The captured images are processed by an external visual analysis device. The analysis device compares the current angle of the carrier tape with a preset standard angle. If a deviation in the angle of the carrier tape is detected, the deviation signal is fed back to the control system for timely processing. The notch 37 and camera 38 work together to form a non-contact online angle detection unit. The camera 38 is embedded inside the notch 37 so that its field of view is not blocked or interfered with by other structures of the equipment. The tubular carrier belt remains naturally unfolded in the detection area. The detection result truly reflects the actual output angle of the carrier belt. The introduction of external visual analysis equipment enables the angle detection to have intelligent interpretation capabilities, and can comprehensively identify various abnormal forms such as carrier belt bending, twisting, and offset.

[0037] In a further preferred embodiment of the present invention, the support frame 1 is provided with a conveyor belt 39 for conveying the assembled terminal, the conveyor belt 39 is located at the bottom of the limiting shell 7, and the limiting shell 7 is provided with a third cylinder for clamping and stabilizing the terminal shell.

[0038] In this embodiment, after the terminal shell slides into the limiting shell 7 via the guide 8, the third cylinder inside the limiting shell 7 is activated to firmly clamp the terminal shell inside the limiting shell 7, so that it remains stable and does not shift during the insertion process. After the insertion assembly is completed, the third cylinder releases the terminal shell, and the assembled connector terminal assembly falls from the bottom of the limiting shell 7 onto the conveyor belt 39 located below it. The conveyor belt 39 continues to run to transport the finished product to the next process area, completing the complete process from insertion assembly to finished product output. By setting up the conveyor belt 39, a seamless connection channel between the plug-in assembly and the finished product output is formed. The assembled connector terminals can fall directly into the conveyor belt 39 without manual handling, realizing continuous flow from the plug-in station to the output station. The third cylinder inside the limiting shell 7 actively clamps and fixes the terminal shell, so that the terminal shell is not disturbed by external force at the moment of terminal insertion, and the plug-in positioning accuracy is reliably guaranteed, avoiding the problem of plug-in misalignment or missing plug-in caused by loose terminal shell.

[0039] To further improve the performance of this device, in addition to the above-mentioned solutions, this solution also includes the following embodiments: In another embodiment of the present invention, two support shafts 40 are rotatably mounted on the support frame 1, and a tubular carrier roller 41 is detachably mounted between the two support shafts 40. A pressure plate 42 is mounted on the support frame 1 to contact the tubular carrier roller 41 and to prevent the tubular carrier roller 41 from rotating. A second motor 43 is fixed on the support frame 1. A fourth gear 45 and a third gear 44 are respectively mounted on the second motor 43 and any one of the support shafts 40. A U-shaped plate 46 is slidably mounted on the support frame 1. A transmission gear 47 that meshes with both the third gear 44 and the fourth gear 45 is rotatably mounted on the U-shaped plate 46. A fourth cylinder is fixed on the support frame 1, and the output rod of the fourth cylinder is connected to the U-shaped plate 46.

[0040] In this embodiment, after the tubular carrier roller 41 is installed between the two support shafts 40, the pressure plate 42 presses against the outer wall of the tubular carrier roller 41 to prevent the carrier belt from getting tangled or loose due to inertial rotation during the feeding process. When it is necessary to feed the tubular carrier belt to the clamping and limiting structure, the fourth cylinder drives the U-shaped plate 46 to slide along the support frame 1. The transmission gear 47 on the U-shaped plate 46 simultaneously engages with the third gear 44 and the fourth gear 45, transmitting power to the support shaft 40. The support shaft 40 drives the tubular carrier roller 41 to rotate and release the tubular carrier belt. Driven by the fourth cylinder, the U-shaped plate 46 can quickly engage and disengage the transmission gear 47 and the gear set, allowing the feeding function of the tubular carrier roller 41 to be started and stopped as needed. The continuous pressing of the pressure plate 42 on the tubular carrier roller 41 eliminates the problem of carrier belt slack or over-spreading caused by the free rotation of the carrier roller. The support shaft 40 is detachably connected to the tubular carrier roller 41, making it easy to replace tubular carrier rollers 41 of different specifications.

[0041] In another embodiment of the present invention, a first connecting shaft 50 and a second connecting shaft 48 are rotatably mounted inside the support frame 1. The second connecting shaft 48 extends outside the support frame 1. A fifth gear 49 is fixed on the second connecting shaft 48. The transmission gear 47 meshes with the fourth gear 45 and the fifth gear 49 simultaneously for transmission. A second bevel gear 51 is mounted on both the first connecting shaft 50 and the second connecting shaft 48. The two second bevel gears 51 mesh with each other. The threaded rod 3 and the first connecting shaft 50 are arranged in groups. A first transmission block 521 is fixed on each of the two first connecting shafts 50. The two first transmission blocks 521 are covered with the same first transmission belt 522. A second transmission block 531 is fixed on each of the two threaded rods 3 and the two first connecting shafts 50. Any two second transmission blocks 531 located on the threaded rod 3 and the first connecting shaft 50 respectively are covered with a second transmission belt 532.

[0042] In this embodiment, when the second motor 43 drives the third gear 44 to rotate, the power is transmitted to the fifth gear 49 via the transmission gear 47, and then to the second connecting shaft 48. Since the second bevel gear 51 on the second connecting shaft 48 meshes with the second bevel gear 51 on the first connecting shaft 50, the rotational motion is transmitted to the first connecting shaft 50. The first transmission block 521 on the first connecting shaft 50 drives another set of first connecting shafts 50 to rotate synchronously via the first transmission belt 522. The second transmission blocks 531 on the two sets of first connecting shafts 50 transmit the power to the two threaded rods 3 respectively via the second transmission belt 532. The two threaded rods 3 rotate synchronously to drive the guide rail 4 to move, thereby realizing the insertion of the terminal. The second connecting shaft 48 and the first connecting shaft 50 are connected by the meshing of the second bevel gear 51, extending the transmission path from the outside of the support frame 1 to the inside. This allows the power of a single second motor 43 to simultaneously drive the two mechanisms of feeding the tubular carrier roller 41 and adjusting the displacement of the outer shell 9 to operate independently. The first transmission belt 522 and the second transmission belt 532 respectively provide synchronous transmission to the first connecting shaft 50 group and the threaded rod 3 group, ensuring that the speed and direction of the two threaded rods 3 are always consistent.

[0043] In another embodiment of the present invention, a base 54 is fixed on the support frame 1, a bracket 55 is fixed on the top of the base 54, a second spring 56 is installed on the inner wall of the top of the bracket 55, a slide 57 is installed on the bottom of the second spring 56, and a clamping roller 58 is rotatably installed on both the slide 57 and the bracket 55. The two clamping rollers 58 cooperate to convey a tubular carrier belt. A third motor 60 is provided on the slide 57 for driving the clamping rollers 58 to rotate. The output shaft of the third motor 60 is connected to the flange of the clamping roller 58 located on the slide 57. The third motor 60 is covered with a protective shell. A guide rod 59 is provided inside the second spring 56 for limiting the spring extension path. The guide rod 59 extends to the top of the bracket 55.

[0044] In this embodiment, after the tubular carrier belt is fed in from the upstream station, it passes through the conveying channel between the two clamping rollers 58 at the top of the clamp 55. The third motor 60 drives the clamping rollers 58 located on the slide 57 to rotate, thereby driving the tubular carrier belt to be conveyed downstream. By setting a clamp 55 and a slide 57 on the base 54, an elastic floating conveying structure is formed, which enables the clamping roller 58 to have adaptive height adjustment capability when conveying tubular carrier belt. When the thickness of the carrier belt changes due to uneven stretching or process fluctuations, the second spring 56 automatically compensates for the gap between the carrier belt and the clamping roller 58, and always maintains a stable clamping contact force, thus avoiding the problem of jamming or slippage caused by the thickness deviation of the carrier belt in the rigid conveying mechanism.

[0045] In summary, compared with related technologies, this device, by setting up an adjustment frame 2, in conjunction with a threaded rod 3 and a guide rail 4, achieves stepless horizontal displacement adjustment of the housing 9, facilitating terminal insertion. By setting up an adjustment mechanism 5, the relative position of the terminal carrier tape and the terminal housing can be adjusted to ensure accurate docking. By setting up a clamping and limiting structure, the extended carrier tape can be supported and limited. In conjunction with a pressure sensor, force feedback insertion depth control can also be achieved to avoid over-insertion or under-insertion and improve the insertion quality.
