Description

Technical Field

[0001] This invention belongs to the field of connector assembly technology, specifically relating to an automatic flattening and pin-installing device for tail-cut flattened contacts and its pin-installing method. Background Technology

[0002] Micro-rectangular wire bonding cup connectors are an important branch of the wire bonding cup connector series. The tail of the contact is flattened. Currently, these connectors are all assembled manually, and there are no successful cases of automated equipment. The reason is that the flattened tail of the contact is a smooth arc surface, and the arc surface is reflective. It is not possible to accurately identify the angle of the flattening by vision. Conventional vibratory feeders cannot adjust the posture of the contacts to be consistent, nor can they arrange the contacts to be discharged in an orderly manner, thus making automated assembly impossible. Summary of the Invention

[0003] The purpose of this invention is to solve the problems existing in the prior art and to provide an automatic flattening and pinning device and a pinning method for tail-cut flattened contact parts. This device can quickly and accurately identify the orientation angle of the tail-cut flattened surface of the contact part, ensuring stable and reliable identification, thereby realizing the automated assembly of tail-cut flattened contact parts.

[0004] To achieve the above objectives, one objective of the present invention is to provide an automatic flattening and needle-loading device for a tail-end flattening contact, comprising an automatic flattening and needle-loading mechanism; the automatic flattening and needle-loading mechanism comprises a flattening rotation component and an optical fiber sensing component;

[0005] The flattening rotary assembly includes a flattening rotary motor, a rotating shaft, a fixed base, an elastic element I, a floating shaft, and a contouring push rod. The rotating shaft is rotatably mounted on the fixed base. A floating cavity is formed along the axial direction of the rotating shaft. The tail end of the floating shaft is installed in the floating cavity. The two can move relative to each other along the axial direction but cannot rotate relative to each other. The tail end of the floating shaft abuts against the head end of the elastic element I in the floating cavity. The head end of the floating shaft extends outward from the floating cavity. The contouring push rod is installed at the head end of the floating shaft and is coaxial with it. The head end of the contouring push rod forms an abutting end face and a contouring mating surface for cooperating with the tail flattening contact element. The abutting end face is used to abut against the tail end face of the tail flattening contact element, and the contouring mating surface is used to mesh with the tail flattening surface of the tail flattening contact element.

[0006] The fiber optic sensing component includes a fiber optic sensing block and a fiber optic sensor. The fiber optic sensing block is disposed on the floating shaft, and the fiber optic sensor is disposed on one side of the floating shaft. The fiber optic sensor is used to determine the displacement of the fiber optic sensing block along the axial direction of the floating shaft by detecting changes in the state of the fiber optic sensing block blocking the light signal, and then to determine whether the contour mating surface and the tail end flattened surface are engaged.

[0007] As a preferred embodiment, when the contouring mating surface and the tail end flattening surface are in a meshing state, the flattening rotary motor drives the contouring push rod to rotate, causing the tail end flattening contact to rotate around its central axis, so that the tail end flattening surface faces a predetermined angle.

[0008] When the contouring mating surface and the tail end flattening surface are not in engagement, the flattening rotary motor drives the contouring push rod to rotate. When the contouring mating surface and the tail end flattening surface rotate to the engagement position, the elastic element I pushes the contouring push rod to undergo an axial position jump to automatically achieve engagement. Then, the flattening rotary motor continues to drive the contouring push rod to rotate, causing the tail end flattening contact to rotate around its central axis, so that the tail end flattening surface faces the predetermined angle.

[0009] As a preferred embodiment, the contact end face is perpendicular to the central axis of the contour push rod.

[0010] As a preferred embodiment, it also includes a pin loading punch; the pin loading punch is movable toward or away from the connector housing, and the pin loading punch has a through cavity for inserting the tail-cut flattened contact and the contour push rod; the pin loading punch includes a punch seat and a support seat for fixing the punch seat, and the punch seat is fixedly mounted on the pin loading sliding block by the support seat.

[0011] As a preferred embodiment, a guide cavity is provided on the top surface of one side of the tail end of the punch seat. An arc-shaped placement groove is formed at the bottom of the guide cavity for orienting the tail-end flattened contact. The arc-shaped placement groove corresponds to and is smoothly connected to the through cavity of the punch seat. A contour push rod is used to push the tail-end flattened contact in the arc-shaped placement groove into the through cavity. A mounting pin is formed on one side of the head end of the punch seat. The head end opening of the through cavity is located on the head end face of the mounting pin.

[0012] As a preferred embodiment, the device further includes a flattening movement assembly; the flattening movement assembly includes a flattening movement slider and a flattening movement motor for driving the flattening movement slider to move; a flattening rotation assembly is mounted on the flattening movement slider; the flattening movement slider is used to first drive the contour push rod to push the head end of the tail-cut flattened contact into the corresponding mounting hole of the connector housing, and then the flattening rotation assembly rotates the tail-cut flattened surface of the tail-cut flattened contact around the axis to a predetermined orientation angle, and finally drives the contour push rod to force the tail-cut flattened contact into place at the target depth of the mounting hole of the connector housing.

[0013] As a preferred embodiment, the assembly further includes a needle-loading moving component; the needle-loading moving component includes a needle-loading moving motor and a needle-loading moving slider, the needle-loading moving motor is used to drive the needle-loading moving slider to reciprocate along the needle-loading direction, and the needle-loading punch and the flattening moving component are mounted on the needle-loading moving slider.

[0014] As a preferred embodiment, a stop platform is formed inside the floating cavity, and a limit head is formed on the floating shaft. The limit head cooperates with the stop platform to stop and limit the movement of the floating shaft away from the floating cavity.

[0015] As a preferred embodiment, the system also includes a carrier drive mechanism, which includes a connector carrier and a carrier drive assembly for driving the connector carrier to move. The carrier drive assembly is used to drive the connector carrier to automatically move to the next mounting hole position after each connector housing mounting hole is installed, so that the mounting hole position corresponds to the through cavity of the punch seat.

[0016] As a preferred embodiment, the vehicle drive assembly includes a horizontal movement assembly and a vertical movement assembly. The horizontal movement assembly includes a base and a horizontal movement platform movably mounted on the base. The vertical movement assembly includes a vertical movement platform and a mounting bracket fixedly mounted on the vertical movement platform. The vertical movement platform is movably mounted on the horizontal movement platform, and the mounting bracket is used for detachably mounting the connector carrier.

[0017] As a preferred embodiment, it also includes a feeding mechanism; the feeding mechanism is used to supply the tail-end flattened contact parts and place them in the punch seat according to a specific arrangement order; the feeding mechanism includes an image recognition component and a needle-picking nozzle, the image recognition component is used to obtain the head-to-tail direction of the tail-end flattened contact parts, and the needle-picking nozzle is used to pick up the tail-end flattened contact parts and place them in the arc-shaped placement groove of the punch seat in the head-to-forward direction.

[0018] The second objective of this invention is to provide a needle loading method for the automatic flattening needle loading device using any of the above-mentioned tail-cutting contact components, comprising the following steps:

[0019] Step 1: The punch moves closer to the mounting hole on the connector housing, and the feeding mechanism grabs the tail-end flattened contact and initially distinguishes the head and tail ends of the tail-end flattened contact.

[0020] Step 2: Place the flattened tail contact with its head facing the connector housing into the guide cavity of the pin-loading punch. The flattened tail contact falls into the arc-shaped placement groove, with its head facing the through cavity. Driven by the flattening slider, the contouring push rod pushes the flattened tail contact into the through cavity of the pin-loading punch. After the head of the flattened tail contact enters the mounting hole of the connector housing by a predetermined length, the fiber optic sensing component determines whether the contouring mating surface and the flattened tail surface are engaged. If the fiber optic sensing component does not detect an engagement signal, the flattening rotary motor drives the contouring push rod to rotate around its axis. When the fiber optic sensing component captures the engagement signal between the contouring push rod and the flattened tail contact, the flattening rotary motor drives the contouring push rod to rotate, causing the flattened tail contact to rotate around its central axis, so that the flattened tail surface faces a predetermined angle. Then, driven by the flattening slider, the contouring push rod installs the flattened tail contact to the target depth of the mounting hole of the connector housing.

[0021] Step 3: After assembling one tail-flattened contact, the carrier drive assembly moves the connector carrier to the next mounting hole, so that the next mounting hole corresponds to the tail-flattened contact in the through cavity, thereby realizing the installation of the tail-flattened contacts in sequence.

[0022] As a preferred embodiment, in step two, the contouring push rod includes an initial position, an engagement judgment position, and a forced installation position; after the contouring push rod moves axially from the initial position to the engagement judgment position, the tail flattened contact's tail end flattened surface rotates around the axis to a predetermined orientation angle; the contouring push rod continues to push the tail flattened contact into the connector housing mounting hole to the target depth, at which point it is the contouring push rod forced installation position;

[0023] The contouring push rod and the tail flattened contact member have two contact working states at the engagement judgment position:

[0024] In the first working state, the contouring push rod abuts against the tail end of the tail-cut flattening contact, and the contouring mating surface directly meshes with the tail-cut flattening surface of the tail-cut flattening contact. The flattening rotary motor drives the contouring push rod to rotate, causing the tail-cut flattening contact to rotate around its central axis, so that the tail-cut flattening surface faces the predetermined angle.

[0025] In the second working state, the contouring push rod abuts against the tail end of the tail-cutting contact. When the abutting end face is in contact with the tail end face of the tail-cutting contact, the flattening rotary motor drives the contouring push rod to rotate through the rotating shaft. When the contouring mating surface is aligned with the tail-cutting flattening surface, the elastic element I pushes the contouring push rod to mesh with the tail-cutting flattening surface. Then, the flattening rotary motor drives the contouring push rod to rotate, causing the tail-cutting contact to rotate around its central axis, so that the tail-cutting flattening surface faces the predetermined angle.

[0026] Beneficial effects

[0027] Firstly, this solution provides an automatic flattening and pinning device for tail-cut flattened contact parts. Through structural improvements, it utilizes the principle that when the flattened surface of the contact part's tail end engages with the conformal mating surface of the conformal push rod, the axial displacement of the conformal push rod will change abruptly. After this abrupt axial displacement, the flattened surface of the contact part's tail end engages with the conformal mating surface of the conformal push rod, accurately finding the orientation angle of the flattened surface of the contact part's tail end. Then, by rotating the conformal push rod by a certain angle, the orientation of the flattened surfaces of all tail-cut flattened contact parts is ensured to be consistent. At this point, the conformal push rod moves forward axially, thereby achieving automatic assembly of the tail-cut flattened contact parts. This mechanical automatic flattening mechanism is accurate and efficient. Using the pinning device of this invention, the problem of automatic assembly of tail-cut flattened contact parts can be effectively solved.

[0028] Secondly, this solution optimizes the pinning method for the tail-end flattened contact. By organically combining it with the aforementioned pinning device, the contact is first roughly positioned using vacuum suction under visual guidance to distinguish the orientation of its head and tail. Then, the contact is placed into the automatic flattening and pinning device. Utilizing the principle that the displacement of the contouring pusher jumps when the tail-end flattened surface of the contact engages with the contouring mating surface of the contact, the orientation angle of the tail-end flattened surface can be accurately found, thus achieving automatic assembly of the tail-end flattened contact. By capturing the axial jump signal of the contouring pusher through a fiber optic sensor head, the flattened orientation angle can be accurately found. At this point, rotating the contouring pusher causes the tail-end flattened surface of the contact to align in a specific direction, maintaining consistency. The contouring pusher then pushes the contact to the target depth of the connector housing, completing the contact assembly. Attached Figure Description

[0070] The present invention will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0071] It should be noted that, unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains. The terms "a," "an," or "the," and similar words used in the specification and claims of this patent application do not express a limitation of quantity, but rather indicate the presence of at least one. Terms such as "comprising" or "including" indicate that the elements or objects preceding "comprising" encompass the elements or objects listed following "comprising" or "including" and their equivalents, but do not exclude other elements or objects having the same function.

[0072] Before introducing the present invention, the structure of the tail-end flattened contact 10 and the connector housing 20 will be described first. The tail-end flattened contact 10 has a cylindrical structure. Its head end has a flat port with a flush surface. Its tail end port is obliquely cut to one side to form a tail-end flattened surface 101. The tail-end flattened surface 101 has an arc surface structure. The tail end without oblique cutting has a flat tail end face 102. In this solution, when the tail-end flattened contact 10 is installed into the corresponding mounting hole of the connector housing 20, the tail-end flattened surface 101 needs to be rotated about an axis to face the same rotation angle to achieve automated assembly (so that the orientation angle of the tail-end flattened surface 101 of all tail-end flattened contacts 10 is consistent). This rotation about an axis refers to rotation about the central axis of the tail-end flattened surface 101. In this invention, for ease of explanation, the end with the tail-end flattened surface 101 is referred to as the tail end of the tail-end flattened contact 10. The connector housing 20 is part of the connector, and after the tail flattened contact 10 mentioned above is installed, the complete product is formed.

[0073] As shown in the figure, this embodiment provides an automatic flattening and pinning device for tail-cut flattened contact parts, including a feeding mechanism 2 and an automatic flattening and pinning mechanism 1. The feeding mechanism 2 provides a continuous supply of tail-cut flattened contact parts 10 to the automatic flattening and pinning mechanism 1, and places the tail-cut flattened contact parts 10 in a head-forward (towards the installation direction) arrangement at the pinning punch 11 of the automatic flattening and pinning mechanism 1. The automatic flattening and pinning mechanism includes a pinning punch 11, a flattening moving component 12, a flattening rotating component 13, a pinning moving component 14, and an optical fiber sensing component 15.

[0074] In this embodiment, the flattening moving assembly 12 includes a flattening moving motor 121, a flattening moving slider 122, and a translation driver I 123. The flattening moving motor 121 drives the flattening moving slider 122 to move via the translation driver I 123. In this design, the translation driver I 123 is a single-axis driver. The flattening moving motor 121 is fixedly mounted on the needle loading moving slider 142, and the flattening moving slider 122 is slidably mounted on the needle loading moving slider 142. The flattening rotating assembly 13 is mounted on the flattening moving slider 122. The flattening moving slider 122 can move towards or away from the punch seat 112 to achieve axial movement of the contour push rod 137. The flattening moving assembly 12 has the following functions: The flattening moving motor 121 drives the flattening moving slider 122 to move through the translation driver I 123, and drives the contouring push rod 137 to push the tail-end flattening contact 10 through the through cavity 113 of the punch seat 112 axially, so that the head end of the tail-end flattening contact 10 enters the corresponding mounting hole of the connector housing 20 to a certain depth. At this time, the tail-end flattening contact 10 is subjected to a certain installation resistance, the elastic element I 135 is compressed, and the contact point between the tail-end flattening contact 10 and the contouring push rod 137 is located in the through cavity 113. In this state, the flattening rotating assembly 13 and the fiber optic sensing assembly 15 cooperate to determine the contour. Whether the push rod 137 and the tail-end flattened contact 10 are in an engaged state. If they are not in an engaged state, the flattening rotary assembly 13 needs to adjust the contour push rod 137 and the tail-end flattened contact 10 to an engaged state. Then, the flattening rotary assembly 13 drives the tail-end flattened contact 10 to rotate around its axis (around the central axis of the tail-end flattened contact 10), thereby adjusting it to have the same orientation angle as the tail-end flattened surface 101. Finally, the flattening moving motor 121 continues to push the flattening moving slider 122, thereby driving the contour push rod 137 to forcefully push the tail-end flattened contact 10 into the mounting hole of the connector housing 20 at a predetermined target depth along the axial direction. In this invention, the flattening rotary motor 131, the flattening moving motor 121, and the pin mounting moving motor 141 are all servo motors.

[0075] The following describes a typical embodiment of the flattening rotary assembly 13: The flattening rotary assembly 13 includes a flattening rotary motor 131, a rotating shaft 132, a fixed base 133, an elastic element I 135, a floating shaft 136, a contouring push rod 137, and a plug head 138. The power output shaft of the flattening rotary motor 131 is connected to the rotating shaft 132 via a coupling 139. The rotating shaft 132 is rotatably mounted in the mounting shaft hole of the fixed base 133. For example, the rotating shaft 132 can be mounted in the shaft hole of the fixed base 133 via a bearing. The rotating shaft 132 has a floating cavity 134 formed along its axial direction. The elastic element I 135 is disposed in the floating cavity 134. The tail end of the floating shaft 136 is connected to the elastic element I 135. The head end of component I 135 abuts against the floating shaft 136, and the head end of the floating shaft 136 extends outward from the floating cavity 134. The floating shaft 136 is fixedly connected to the contour push rod 137 located at its head end and is coaxially arranged. The tail end of the elastic component I 135 abuts against the plug head 138. The plug head 138 is screwed into the internal thread of the tail end face of the floating cavity 134. After the elastic component I 135 and the floating shaft 136 are installed into the floating cavity 134 from the tail end, the plug head 138 seals the elastic component I 135 and the floating shaft 136 in the floating cavity 134 from the tail end. By adjusting the axial position of the plug head 138 in the floating cavity 134, it can be used to press against the tail end of the elastic component I 135 (spring) and adjust the spring force. The outer surface of the floating shaft 136 has a side plane 1362 arranged along the axial direction, and the inner wall of the floating cavity 134 has an anti-rotation surface 1342. The side plane 1362 and the anti-rotation surface 1342 are correspondingly matched, thereby restricting the floating shaft 136 to only move along the axial direction in the floating cavity 134 and not to rotate relative to it. At the same time, when the rotating shaft 132 rotates, the floating shaft 136 will rotate synchronously with the rotating shaft 132 to achieve the purpose of driving the contour push rod 137 to rotate around the axis. The elastic element I135 is a spring. The head end of the contour push rod 137 has a contour mating surface 1371 that mates with the tail end flattened surface 101 of the tail end flattened contact element 10, and an abutting end surface 1372 that abuts with the tail end face 102. Preferably, the abutting end surface 1372 is a planar structure and is perpendicular to the central axis of the contour push rod 137. When the contour mating surface 1371 and the tail end flattened surface 101 are adapted to mesh (refer to...), Figure 13 As shown at point A), the contouring push rod 137 drives the tail-end flattened contact member 10 to rotate, and the two rotate synchronously without relative rotation; when the abutting end face 1372 abuts against the tail end face 102 of the tail-end flattened contact member 10 (refer to... Figure 14As shown at point B in the middle, the two can rotate relative to each other to find the engagement point. When the two rotate to the state corresponding to the engagement point, the compressed elastic element I 135 will push the contouring push rod 137 to engage with the tail flattening contact element 10 (the contouring mating surface 1371 engages with the tail flattening surface 101). The purpose of setting the elastic element I 135 is as follows: when the flattening moving slider 122 moves forward from the initial position to a predetermined distance, firstly, the elastic element I 135 is compressed to a certain extent, and the compressed elastic element I 135 will push the contouring push rod 137 to engage with the tail flattening contact element 10 along the axial direction. Secondly, the elastic element I 135 cooperates with the fiber optic sensing component 15. The elastic element I 135 pushes the contouring push rod 137 to undergo an axial position transition. Based on the axial position transition signal collected by the fiber optic sensing component 15, it is determined whether the contouring push rod 137 and the tail flattening contact 10 are properly engaged. The flattening rotary motor 131 is a servo motor, which obtains the rotation angle of the contouring push rod 137 around the axis at this time. Thus, it is possible to obtain the rotation angle of the tail flattening surface 101 of the tail flattening contact 10 around the axis. Based on this, the tail flattening contact 10 is rotated around the axis for the next step, so that the tail flattening contact 10 is finally rotated around the axis until the tail flattening surface 101 faces the same direction.

[0076] In this design, a stop platform 1341 is formed near the head end of the floating cavity 134, and a limit head 1361 is provided at the tail end of the floating shaft 136. The stop platform 1341 cooperates with the limit head 1361 to prevent the floating shaft 136 from coming out of the floating cavity 134. An optical fiber sensing block 151 is fixedly installed on the head end port of the floating shaft 136, and an optical fiber sensor 152 is provided on one side of the floating shaft 136. The optical fiber sensor 152 is used to detect the optical fiber sensing block 151 to determine the axial position of the floating shaft 136. Since the optical fiber sensing block 151 will undergo a positional jump along the axial direction with the floating shaft 136, if the light signal of the optical fiber sensor 152 is no longer blocked by the optical fiber sensing block 151 (e.g., ...), ... Figure 13 The sensor 152 determines that the contouring mating surface 1371 of the contouring push rod 137 engages with the tail end flattening surface 101 of the tail flattening contact 10, and transmits this signal.

[0077] In this embodiment, the pin-loading moving assembly 14 includes a base 143, a pin-loading moving motor 141 mounted on the base 143, a pin-loading moving slider 142, and a translation driver II 144. The pin-loading moving motor 141 drives the pin-loading moving slider 142 to move relative to the base 143 via the translation driver II 144. The pin-loading moving slider 142 is also provided with a pin-loading punch 11. By driving the pin-loading punch 11 to move axially, the pin-loading punch 11 is aligned with the mounting hole of the connector housing 20 and maintains a certain distance from the opening of the mounting hole, thereby facilitating the smooth insertion of the tail-cutting contact 10, which has completed the flattening orientation, into the connector housing 20. The pin-loading moving slider 142 is also provided with a flattening moving assembly 12, thereby driving the flattening moving assembly 12 and the flattening rotating assembly 13 to move synchronously as a whole. The needle loading slider 142 is mounted on the translation driver II 144, which is a single-axis driver. The driving force is input to the translation driver II 144 through the needle loading motor 141.

[0078] In a typical embodiment of the present invention, the pin loading punch 11 includes a support base 111 and a punch seat 112 mounted on the support base 111. The support base 111 is mounted on the pin loading sliding block 142. The punch seat 112 has a through cavity 113 for accommodating the tail-end flattened contact 10 and the contour push rod 137. The through cavity 113 provides peripheral restriction for the relative rotation of the tail-end flattened contact 10 and the contour push rod 137, so that they can maintain the consistency of their axial direction during relative rotation or synchronous rotation. The support base 111 is fixedly mounted on the pin loading moving assembly 14, which can drive the support base 111 to translate axially, thereby moving the punch seat 112 away from or towards the mounting hole of the connector housing 20.

[0079] In this invention, a V-shaped guide cavity 114 for placing the tail-end flattened contact 10 is provided on the top of the punch base 112 near the tail end. A mounting pin 116 is integrally provided around the periphery of the through cavity 113 at the other end of the punch base 112. The mounting pin 116 is designed to correspond to the mounting holes of the connector housing 20 and to avoid interference between the mounting mechanism and adjacent tail-end flattened contacts 10 that have already been installed in the connector housing 20. The two sides of the guide cavity 114 are inclined planes. The tail-end flattened contact 10, placed in the guide cavity 114, can slide down the inclined plane to the bottom. An arc-shaped placement groove 115 is formed at the bottom of the guide cavity 114. The connection between the arc-shaped placement groove 115 and the through cavity 113 is a smooth transition and the two correspond to each other. The arc-shaped placement groove 115 plays a preliminary role in correcting the position orientation of the tail-end flattened contact 10. The arc-shaped placement groove 115 is formed by extending the side wall of the through cavity 113 so that the tail-end flattened contact 10 located in the arc-shaped placement groove 115 can be pushed into the through cavity 113 without additional obstruction.

[0080] In this scheme, after the feeding mechanism 2 places the tail-flattened contact 10 into the guide cavity 114, the tail-flattened contact 10 will automatically correct its direction and enter the arc-shaped placement groove 115 to achieve automatic correction of its placement direction, so that its head end is facing the through cavity 113. The contour push rod 137 pushes the tail end of the tail-flattened contact 10, so that the head end of the tail-flattened contact 10 passes through the through cavity 113 and enters the mounting hole of the connector housing 20 for a predetermined distance (at this time, the tail-flattened contact 10 is subject to a certain installation resistance from the mounting hole of the connector housing 20, but no rotational constraint is formed around its central axis, and it has rotational freedom around its central axis). The elastic element I 135 will be compressed to a certain extent, and the contact point between the contour push rod 137 and the tail-flattened contact 10 (this contact point refers to the contact position of the two parts) is located in the through cavity 113. If it is determined that the contouring push rod 137 and the tail flattening contact 10 are in a meshing state (there is still a certain possibility that the contouring push rod 137 and the tail flattening contact 10 may mesh perfectly), then the flattening rotary motor 131 will directly drive the contouring push rod 137 to rotate, so that the tail flattening contact 10 rotates around the axis to a specific orientation angle position, so that all the installed tail flattening contact 10 have the same overall orientation angle. At this time, if it is determined that the contouring push rod 137 and the tail flattening contact 10 are not meshing... In the engaged state (when the contouring push rod 137 contacts the tail flattened contact 10, but they are not in the directly opposite meshing position, and the abutting end face 1372 abuts against the tail end face 102 of the tail flattened contact 10), the flattening rotary motor 131 will drive the contouring push rod 137 to rotate. When the contouring push rod 137 rotates to the position directly opposite the tail flattened contact 10, the elastic force stored in the elastic element I 135 will push the contouring push rod 137 to move axially, thereby making the contouring push rod 137 mesh with the tail flattened contact 10. Then the flattening rotary motor 131 will drive the contouring push rod 137 to rotate, so as to move the tail flattened contact 10 to a specific orientation position, so that the overall orientation angle of all installed tail flattened contact 10s is consistent.

[0081] This solution also includes a feeding mechanism 2 and a vibratory feeder mechanism 5. The feeding mechanism 2 is used to feed the tail-end flattened contact parts 10 and place them at the needle loading punch 11 of the automatic flattening needle loading mechanism 1 in a head-forward arrangement. The feeding mechanism 2 includes a needle-picking nozzle 21, an image recognition component 22, and a needle-picking robot 23. The vibratory feeder mechanism 5 is a flexible vibratory feeder, including a feeding tray 51 and a holding tray 52. ​​The holding tray 52 is used to hold the tail-end flattened contact parts 10 and vibrates them apart to facilitate the suction and pickup by the needle-picking nozzle 21. The needle-picking nozzle 21 can be vacuum suction. The bottom of the holding tray 52 is backlit to facilitate the image recognition component 22 in acquiring image information of the tail-end flattened contact parts 10. The feeding tray 51 can be used to intermittently feed the holding tray 52. ​​The image recognition component 22 can be a CCD camera, used to take pictures of the tail-cut flattened contact 10 placed inside the holding tray 52. ​​Based on the different structures at both ends of the component, the head end and tail end of the tail-cut flattened contact 10 are initially distinguished. The needle-retrieving nozzle 21 is used to adsorb the middle part of the tail-cut flattened contact 10. The needle-retrieving robot 23 is used to transport the adsorbed tail-cut flattened contact 10 to the punch seat 112 and place it into the guide cavity 114 of the punch seat 112 according to the direction of the head end and tail end of the tail-cut flattened contact 10 (with the tail end of the tail-cut flattened contact 10 facing the contour push rod 137).

[0082] In a typical embodiment of the present invention, an optical fiber sensing component 15 is further included. The optical fiber sensing component 15 includes an optical fiber sensing block 151 and an optical fiber sensor 152. The optical fiber sensing block 151 is fixedly mounted on the floating shaft 136 and can move axially with the floating shaft 136. The optical fiber sensor 152 is mounted on a mounting base on one side of the floating shaft 136. The mounting base is fixed on the flattening moving slider 122. The optical fiber sensor 152 is used to detect the position of the optical fiber sensing block 151 to determine whether the tail flattening contact 10 and the contouring push rod 137 are in an engaged state. It is also used to capture the transition signal of the contouring push rod 137 along the axial position to send a signal to the control mechanism that the tail flattening contact 10 and the contouring push rod 137 are not in an engaged state, thereby driving the flattening rotation component 13 to achieve further flattening angle orientation adjustment.

[0083] In this embodiment, the carrier drive mechanism 3 includes a connector carrier 33 and a carrier drive assembly for moving the connector carrier 33. The carrier drive assembly is used to drive the connector carrier 33 to automatically move to the next mounting hole after each mounting hole of the connector housing 20 is installed, so that the mounting hole corresponds to the flattened contact 10 to be installed in the through cavity 113. The carrier drive assembly includes a horizontal moving assembly 31 and a vertical moving assembly 32. The horizontal moving assembly 31 includes a base 311, a horizontal moving motor 312, a horizontal moving shaft 314, and a horizontal moving platform 313. The vertical moving assembly is disposed on the horizontal moving platform 313. The vertical moving assembly 32 includes a mounting base 321, a vertical moving motor 322, a vertical moving shaft 324, and a vertical moving platform 323. The mounting base 321 is fixedly installed on the vertical moving platform 323. A slot 3211 is provided on the end face of the mounting base 321. The slot 3211 is used to install the connector carrier 33. The slot 3211 has a dovetail groove structure. The connection structure of the connector carrier 33 is adapted to the structure of the slot 3211. The connector carrier 33 is installed in the slot 3211 and fixed by the fastener 3212. The connector carrier 33 includes a carrier body 331 and a pressure block locking assembly provided on the carrier body 331. The carrier body 331 is provided with a mounting position for the connector housing 20. The edge of the carrier body 331 forms a fixing groove 332. The fastener 3212 on the slot 321 can be screwed into the fixing groove 332 to tighten and fix the connector carrier 33, preventing the carrier from shifting during assembly. Fastener 3212 uses a tightening screw. The pressure block locking assembly includes an elastic element II 333, a cam knob 334, and a pressure block 335. The pressure block 335 is disposed in a groove 336 of the carrier body 331. The elastic element II 333 is disposed between the side wall of the groove 336 and the pressure block 335. A groove is formed on one side of the pressure block 335 to accommodate the end of the elastic element II 333. Preferably, the elastic element II 333 is a spring and two springs are arranged in parallel. The elastic element II 333 is used to push the pressure block 335 to press the connector housing 2. 0 and fix it. The cam knob 334 is provided with an elliptical cam block. When the long diameter end of the cam knob 334 is turned to be consistent with the clamping force direction of the elastic element II 333, the cam knob 334 is used to lift the pressure block 335 and compress the elastic element II 333 to unlock the connector housing 20. When the short diameter end of the cam knob 334 is turned to be consistent with the clamping force direction of the elastic element II 333, the elastic element II 333 will push the pressure block 335 down to the tail end surface of the connector housing 20 to lock it.

[0084] In this design, the carrier drive mechanism 3 achieves the alignment of the connector carrier 33 with the installation position through the movement of the horizontal moving platform 313 and the vertical moving platform 323. By cooperating with the horizontal moving component 31 and the vertical moving component 32, the connector housing 20 can be moved to a position directly opposite the through cavity 113 of the pin insertion punch 11. At this time, the pin insertion moving motor 141 drives the translation driver II 144 and moves the punch seat 112, causing the mounting pin 116 of the punch seat 112 to align with the mounting hole of the connector housing 20, thus smoothly inserting the tail-cut flattened contact 10, which has completed its flattening and orientation, into the connector housing 20.

[0085] The pin-finding and pin-loading mechanism of the present invention includes a pin-loading punch 11, a pin-finding moving assembly 12, a pin-finding rotating assembly 13, a pin-loading moving assembly 14, and an optical fiber sensing assembly 15. The pin-loading moving assembly 14 drives the pin-loading punch 11, the pin-finding moving assembly 12, the pin-finding rotating assembly 13, and the optical fiber sensing assembly 15 to move as a whole, and cooperates with the carrier drive mechanism 3 to achieve the proximity and alignment of the pin-loading punch 11 with the mounting hole of the connector housing 20. The pin-finding moving assembly 12 first initially pushes the contour push rod 137 to achieve a small amount of entry of the tail-cut flattened contact 10 into the connector housing 20. Then, the pin-finding rotating assembly 13 utilizes the tail-cut flattening feature of the tail-cut flattened contact 10 to move the pin-loading punch 11 closer to and aligned with the mounting hole of the connector housing 20. When the tail-end flattened surface 101 of the tail-end flattened contact 10 engages, the elastic element I 135 pushes the axial position of the contour push rod 137 to change abruptly. The fiber optic sensing component 15 captures this position change and can accurately find the orientation angle of the tail-end flattened surface 101. Based on this information, the contour push rod 137 is rotated, causing the tail-end flattened surface 101 of the tail-end flattened contact 10 to face a specific direction. At this time, the flattening moving component 12 pushes the tail-end flattened contact 10 to the target depth of the connector housing 20 through the contour push rod 137, thus completing the assembly of the tail-end flattened contact 10. This mechanical flattening structure is accurate and efficient, and can effectively solve the problem of automatic flattening assembly of the tail-end flattened contact 10.

[0086] The flattening and pinning method of the present invention, under visual guidance and using vacuum suction, first roughly positions the tail-end flattening contact 10, distinguishes the head and tail directions of the tail-end flattening contact 10, and then places the tail-end flattening contact 10 into the automatic flattening and pinning device. Utilizing the principle that when the tail-end flattening surface 101 of the tail-end flattening contact 10 engages with the contouring mating surface 1371 of the contouring push rod 137, the displacement of the contouring push rod 137 will change abruptly, the orientation angle of the tail-end flattening surface 101 can be accurately found, thereby realizing the automatic assembly of the tail-end flattening contact 10.

[0087] This embodiment also provides an automatic flattening and pin-installing method for tail-cut flattened contact components, which employs the aforementioned automatic flattening and pin-installing device for tail-cut flattened contact components and includes the following steps:

[0088] Step 1: The needle punch 11 moves close to the mounting hole of the connector housing 20 on the connector carrier 33, and the feeding mechanism 2 grabs the tail flattened contact 10 and initially distinguishes the head and tail ends of the tail flattened contact 10.

[0089] Specifically, the carrier drive mechanism 3 moves the target pin hole of the connector housing 20 and the through cavity 113 of the pin punch 11 to the same axial position, and then the pin moving motor 141 drives the pin punch 11 to move closer to the target pin hole on the connector carrier 33 to a certain distance and then stops.

[0090] First, the image recognition component 22 is used to take a picture of the tail-end flattened contact 10 in the feeding tray 51 to obtain an image of the tail-end flattened contact 10, so as to initially distinguish the head and tail ends of the tail-end flattened contact 10. Then, the needle suction nozzle 21 is used to pick up the middle section of the tail-end flattened contact 10, and the tail-end flattened surface 101 of the tail-end flattened contact 10 is oriented towards the contour push rod 137, so as to put the tail-end flattened contact 10 into the V-shaped guide cavity 114.

[0091] Step 2: Place the tail-end flattened contact 10 with its head end facing the connector housing 20 into the guide cavity 114 of the pin-loading punch 11. The contouring push rod 137, driven by the flattening slider 122, pushes the tail-end flattened contact 10 into the pin-loading punch 11. When the axial movement position is reached, if the fiber optic sensing component 15 does not detect the engagement signal, the flattening rotary motor 131 continues to rotate until the engagement signal is captured. When the contouring push rod 137 captures the axial displacement jump signal, the flattening rotary motor 131 then rotates the tail-end flattened surface 101 of the tail-end flattened contact 10 to a specific direction. At this time, the contouring push rod 137, driven by the flattening slider 122, forcibly installs the tail-end flattened contact 10 into the target depth.

[0092] Specifically, the contouring push rod 137 then pushes the tail-end flattened contact 10 forward a certain distance. At this time, the contact point between the contouring push rod 137 and the tail-end flattened contact 10 is located inside the through cavity 113 (at this time, the head end of the tail-end flattened contact 10 extends into the mounting hole of the connector housing 20, while the tail end remains inside the through cavity 113). Since the tail-end flattened contact 10 requires a certain amount of force to be installed into the connector housing 20, the contouring push rod 137 is subjected to the tail-end flattened contact... The installation resistance of contact 10 will compress elastic element I 135. If fiber optic sensing block 151 is sensed by fiber optic sensor 152, the contouring push rod 137 and the tail-end flattened contact 10 will not engage. Rotating the rotating shaft 132 will cause the floating shaft 136 to rotate synchronously with the rotating shaft 132. During rotation, when the contouring mating surface 1371 of the contouring push rod 137 and the tail-end flattened surface 101 of the tail-end flattened contact 10 find the engagement point, the floating shaft 136 will... Under the action of the elastic force of the elastic element I135, the fiber optic sensing block 151 will move axially. The fiber optic sensing block 151 will change axially along the floating shaft 136. The light signal of the fiber optic sensor 152 will no longer be blocked by the fiber optic sensing block 151. After the fiber optic sensor 152 transmits this transition signal, it is determined that the contouring mating surface 1371 of the contouring push rod 137 is engaged with the tail end flattened surface 101 of the tail flattened contact 10. That is, the orientation of the tail end flattened surface 101 of the tail flattened contact 10 is found. Then, based on this information, the orientation angle of the tail flattened contact 10 is rotated to a specific direction by the flattening rotary motor 131. This ensures that the orientation angle of the tail end flattened surface 101 of the tail flattened contact 10 is consistent. The flattening moving motor 121 can continue to translate by driving the contouring push rod 137, thereby forcibly installing the tail flattened contact 10 into the mounting hole of the connector housing 20 until the target depth. Thus, the assembly of a tail flattened contact 10 is completed.

[0093] Step 3: After the assembly of a tail-flattened contact 10 is completed, the carrier drive assembly drives the connector carrier 33 to move to the next hole position, so that the next hole position corresponds to the installation position of the tail-flattened contact 10.

[0094] Specifically, after assembling one tail-flattened contact 10, the connector housing 20 is moved according to the position of the next hole, using the horizontal moving component 31 and / or the vertical moving component 32. The flattening moving motor 121 drives the flattening rotating component 13 to translate and reset. Then, the feeding mechanism 2 places the next tail-flattened contact 10 into the guide cavity 114. The above steps are repeated to ensure that the mounting holes of the connector housing 20 correspond precisely to the tail-flattened contacts 10 in the pin-loading punch 11, thereby achieving the sequential installation of the tail-flattened contacts 10.

Step 2: Place the tail-flattened contact (10) with its head facing the connector housing (20) into the guide cavity (114) of the pin-loading punch (11). The tail-flattened contact (10) falls into the arc-shaped placement groove (115), and the head of the tail-flattened contact (10) is directly facing the through cavity (113). Under the action of the flattening slider (122), the contouring push rod (137) pushes the tail-flattened contact (10) into the through cavity (113) of the pin-loading punch (11). After the head of the tail-flattened contact (10) enters the mounting hole of the connector housing (20) by a predetermined length, the fiber optic sensing component (15) determines the conformal mating surface (1371) and the tail-flattened contact. Whether the face (101) is engaged, if the fiber optic sensing component (15) does not detect the engagement signal, the flattening rotary motor (131) drives the contour push rod (137) to rotate around the axis. When the fiber optic sensing component (15) captures the engagement signal between the contour push rod (137) and the tail flattening contact (10), the flattening rotary motor (131) drives the contour push rod (137) to rotate, causing the tail flattening contact (10) to rotate around its central axis, so that the tail flattening face (101) faces the predetermined angle. Then, under the drive of the flattening moving slider (122), the contour push rod (137) installs the tail flattening contact (10) into the target depth of the mounting hole of the connector housing (20). Step 3: After the assembly of one tail-flattened contact (10) is completed, the carrier drive assembly drives the connector carrier (33) to move to the next mounting hole position, so that the next mounting hole position corresponds to the tail-flattened contact (10) in the through cavity (113), thereby realizing the installation of the tail-flattened contact (10) in sequence.

13. The needle loading method of the automatic flattening needle loading device for the tail-end flattening contact element according to claim 12, characterized in that: In step two, the contour push rod (137) includes an initial position, an engagement judgment position, and a forced installation position. After the contour push rod (137) moves axially from the initial position to the engagement judgment position, the tail flattened surface (101) of the tail flattened contact (10) rotates around the axis to the predetermined orientation angle. The contour push rod (137) continues to push the tail flattened contact (10) into the mounting hole of the connector housing (20) to the target depth. At this time, it is the forced installation position of the contour push rod (137). The contouring push rod (137) and the tail-end flattened contact member (10) have two contact working states at the engagement judgment position: In the first working state, the contour push rod (137) abuts against the tail end of the tail flattening contact (10), and the contour mating surface (1371) directly meshes with the tail end flattening surface (101) of the tail flattening contact (10). The flattening rotary motor (131) drives the contour push rod (137) to rotate, causing the tail flattening contact (10) to rotate around its central axis, so that the tail end flattening surface (101) faces the predetermined angle. In the second working state, the contour push rod (137) abuts against the tail end of the tail flattening contact (10). When the abutting end face (1372) abuts against the tail end face (102) of the tail flattening contact (10), the flattening rotary motor (131) drives the contour push rod (137) to rotate through the rotating shaft (132). When the contour mating surface (1371) and the tail flattening surface (101) are aligned, the elastic element I (135) pushes the contour push rod (137) to mesh with the tail flattening surface (101). Then the flattening rotary motor (131) drives the contour push rod (137) to rotate, causing the tail flattening contact (10) to rotate around its central axis, so that the tail flattening surface (101) faces the predetermined angle.
