Description

Technical Field

[0001] This invention belongs to the field of electrical connector processing technology, specifically a feeding device for electrical connector processing. Background Technology

[0002] Electrical connectors are key components in electrical systems used to connect and disconnect circuits. They are widely used in aerospace, new energy, automotive, and industrial control fields. Their core function is to establish a stable transmission channel for current and signals, while ensuring the reliability, sealing, and mating life of the connection. An electrical connector consists of two main parts: a male connector (plug / male terminal) and a female connector (socket / female terminal). The final product of an electrical connector is a complete connection system. The core purpose of manufacturing is not to produce individual male or female connectors, but to create an assembly that can be directly used for cable connection. Only by accurately mating and securing the male and female connectors can the pins and sockets form a stable electrical contact, enabling effective transmission of current and signals. If the mating is not completed, the product is just a disassembled part and cannot achieve its core function. In actual applications, electrical connectors need to withstand vibration, mating forces, and environmental loads. The mating process during manufacturing (such as thread tightening and snap locking) locks the male and female connectors into a whole through a mechanical linkage structure. This ensures that the male and female connectors will not loosen, fall off, or misalign during use, thereby guaranteeing the long-term stability and mechanical strength of the connection.

[0003] Traditional devices still have some shortcomings in the material handling of components required for electrical connector processing: 1. The existing equipment cannot achieve precise synchronous docking between the male and female seats. The male seat conveying and the female seat repositioning are not synchronized, which can easily lead to misalignment of the workstations and docking failure. At the same time, the lifting action is not stable during docking, and the thread tightening action is not triggered accurately, which can easily lead to problems such as dry tightening and misalignment. This results in low assembly efficiency and insufficient docking accuracy, which cannot meet the requirements of continuous and high-precision assembly. 2. Existing clamping mechanisms are mostly designed with fixed spacing, which cannot adapt to the clamping requirements of different specifications of male seats. Frequent tooling changes are required, increasing production costs. In addition, the lack of limit protection structure during clamping makes it easy for the jaws to open and close excessively, damaging the male seat. At the same time, the thread tightening action is easy to be accidentally triggered, further affecting the assembly integrity of the male and female seats. 3. The existing device lacks an effective protective structure. During the descent of the male seat, it is easy to deviate or tilt, affecting the clamping accuracy. Dust, iron filings and other impurities in the processing workshop can easily enter the internal transmission structure of the device, affecting the stability of the structure. In addition, the lifting and resetting actions of each linkage structure are not stable, which can easily cause structural wear, resulting in a shortened service life of the equipment and an increase in maintenance frequency and cost. Summary of the Invention

[0004] The purpose of this invention is to provide a feeding device for the processing of electrical connectors, so as to solve the problems mentioned in the background art.

[0005] The objective of this invention can be achieved through the following technical solutions: A feeding device for processing electrical connectors includes a frame, an outer cylinder mounted on the frame via a motor, a turntable fixedly mounted on the outside of the outer cylinder, multiple circumferentially arranged card holders on the turntable, triangular chucks inside the card holders for fixing the female connectors used in the connectors, a support plate fixedly mounted at the rear of the frame, a transfer box mounted on the support plate via a lifting part, a feeding port on one side of the upper end face of the transfer box, a transport frame rotatably mounted inside the transfer box, a limiting groove corresponding to each of the multiple card holders on the outer edge of the transport frame, a through opening on one side of the lower end face of the transfer box corresponding to one limiting groove, an operating box below the through opening, a central cylinder connected to the transfer box fixedly mounted at the center of the operating box, a clamping part inside the operating box, a rotating rod rotatably mounted on one side of the clamping part, a gear fixedly mounted on the outer side of the rotating rod located inside the operating box, and a drive part for controlling the rotation of the rotating rod slidably mounted at the bottom of the operating box.

[0006] Preferably, the lifting unit includes a positioning column mounted on a support plate, a slide rail slidably mounted on the positioning column, a spring sleeved on the outside of the positioning column below the slide rail, and a pressing part in the middle of the slide rail to control the lifting and lowering of the slide rail on the positioning column.

[0007] The extrusion section includes two symmetrically arranged hollow frames mounted on a carriage. A side frame is rotatably mounted between the two hollow frames. A cam contacts the top of the side frame. An extension rod is fixedly mounted on one side of the cam. The extension rod is rotatably connected to the support plate via a motor.

[0008] Preferably, an inner rod is vertically slidably installed in the inner cavity of the outer cylinder, and multiple circumferentially arranged slots are opened in the inner cavity of the outer cylinder. Each slot has a locking strip slidably installed in it, and the sides of the locking strips that are close to each other are fixedly connected to the inner rod. One side of the slide is rotatably connected to the round shaft at the top of the transport frame, and the other side of the slide is rotatably connected to the outside of the inner rod. Both the top of the inner rod and the round shaft at the top of the transport frame are equipped with pulleys, and a belt is installed between the two pulleys.

[0009] Preferably, the clamping part includes a tensioning gear ring located in the inner cavity of the operating box. An inner ring is rotatably mounted on the inner side of the tensioning gear ring. Multiple connecting plates are circumferentially mounted on the top of the inner ring. A gear ring rotatably connected in the inner cavity of the operating box is mounted between the multiple connecting plates. An electric push rod is provided on one side of the gear ring. A stop block is fixedly mounted on the telescopic end of the electric push rod.

[0010] Preferably, the tensioning gear ring has multiple circumferentially arranged arc-shaped grooves, a vertical rod is slidably installed in the arc-shaped grooves, and a sliding frame that slides on the upper part of the connecting plate is fixedly installed on the top of the vertical rod. Symmetrically arranged grippers are fixedly installed on the side of the multiple sliding frames that are close to each other.

[0011] Preferably, the drive unit includes a lifting plate that passes through and slides in the control box. A contact plate is fixedly installed at the bottom of the lifting plate. Symmetrical lifting rods are provided on both sides of the upper surface of the contact plate. The lifting rods pass through and slide along the side of the control box. A spring is also sleeved on the outside of the lifting rods to abut against the contact plate. An L-shaped top component is fixedly installed on one side of the top of the lifting plate.

[0012] Preferably, the drive unit further includes a positioning frame fixed to the control box. A crossbar is horizontally mounted on the positioning frame, and a bent slide member set at a right angle is slidably mounted on the crossbar. A toothed plate is fixedly mounted on one end of the bent slide member. A gear two fixed to the top of the rotating rod is meshed on the inner side of the toothed plate. A driven wedge block is fixedly mounted on the side of the toothed plate away from the gear two. An active wedge block is provided below the driven wedge block. The active wedge block is fixedly connected to the top component through a connecting rod.

[0013] Preferably, the inner cavity of the central cylinder is provided with a guide tube, the upper end face of which is fixed to the opening, so that the male seat on the opening can be vertically dropped into multiple grippers through the guide tube.

[0014] The beneficial effects of this invention are: 1. This invention improves assembly efficiency and precision through precise synchronous docking of the male and female seats. The outer cylinder and inner rod are slidably engaged by a locking strip and a locking groove, which not only allows the inner rod to rotate synchronously with the outer cylinder but also allows it to rise and fall axially. The slide is rotatably connected to the upper rotating shaft of the transport frame and the outer side of the inner rod, and is driven by pulleys and belts to synchronize the rotation speed and work position of the outer cylinder, turntable and transport frame, ensuring that the female seat on the locking frame and the male seat in the limiting groove are precisely aligned. At the same time, the spring on the outside of the positioning column in the lifting part is linked with the cam and the side frame to drive the slide to smoothly lift and lower the transfer box and the control box, so that the male and female seats are precisely docked and misalignment is avoided. After the contact plate contacts the locking frame, it links the lifting plate, connecting rod, wedge block group and toothed plate to trigger the rotation of the rotating rod, so as to achieve threaded fastening of the male and female seats. The entire linkage is smooth, which greatly improves the continuous assembly efficiency and docking accuracy.

[0015] 2. This invention utilizes the linkage between the tensioning gear ring and the internal ring and connecting plate in the clamping part. After the electric push rod pushes the stop block to limit the gear ring, the tensioning gear ring rotates and slides with the vertical rod through the arc groove. The linkage sliding frame drives the gripper to synchronously contract or expand radially, which can accommodate different specifications of male seats without frequent tooling changes. At the same time, the rotation angle of the tensioning gear ring is limited by the electric push rod and the stop block, preventing excessive opening and closing of the gripper from damaging the male seat. The spring outside the lifting rod of the drive part is linked with the contact plate, which not only buffers the hard contact wear between the contact plate and the bracket, but also ensures accurate reset of the contact plate and avoids accidental triggering of the thread tightening action, further ensuring the integrity of the male and female seats during clamping and docking.

[0016] 3. The central cylinder and guide tube of this invention are linked, which not only provides vertical guidance for the male seat falling from the opening, ensuring that the male seat falls accurately into the gripper, but also forms a closed conveying space to prevent dust and iron filings from entering the control box. The transfer box semi-encloses the transport frame, and the linkage limiting groove prevents the male seat from falling or shifting during transportation, keeping the processing site clean. In addition, the sliding cooperation between the inner rod and the outer cylinder, along with the linkage strip and groove, protects the internal transmission structure and prevents impurities from affecting the rotation and sliding effect. The elasticity of the springs in each linkage structure ensures smooth lifting and resetting actions, reduces structural wear, extends the service life of the equipment, and reduces the maintenance frequency and cost caused by impurities and structural wear.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-9 As shown, the present invention is a feeding device for processing electrical connectors, including a frame 1, an outer cylinder 111 is rotatably mounted on the frame 1 via a motor, a turntable 10 is fixedly mounted on the outside of the outer cylinder 111, a plurality of circumferentially arranged card holders 11 are provided on the turntable 10, and triangular chucks are provided in the card holders 11 to fix the female sockets used by the connectors. A support plate 6 is fixedly mounted at the rear of the frame 1, and a transfer box 2 is mounted on the support plate 6 via a lifting part. A feeding port 20 is opened on one side of the upper end face of the transfer box 2, and a transport frame 201 is rotatably mounted in the inner cavity of the transfer box 2. A limiting groove 202 corresponding to the plurality of card holders 11 is opened on the outer edge of the transport frame 201, and a through-hole 203 corresponding to the limiting groove 202 is opened on one side of the lower end face of the transfer box 2. An operation box 3 is provided below the through-hole 203. The box structure of the transfer box 2 forms a semi-enclosed enclosure for the transport frame 201, preventing the material from falling due to centrifugal force or vibration during the flipping and transportation process, thus realizing closed management of materials and maintaining the cleanliness of the processing site. In the lifting unit, the spring sleeved on the outside of the positioning column 61 not only provides a buffer for the downward movement of the slide 62, reducing the impact force on the male and female seats when the operating box 3 moves down, and avoiding structural damage during docking; it can also accurately drive the slide 62, the transfer box 2, and the operating box 3 to reset after the cam 68 cancels the squeezing of the side frame 66, ensuring the consistency of each lifting action and guaranteeing the docking and fastening accuracy. In the drive unit, the crossbar 57 on the positioning frame 56 guides the bent slide 58, ensuring that the bent slide 58 drives the toothed plate 59 to slide smoothly, thereby ensuring the stable meshing of the toothed plate 59 and the gear 481 and avoiding transmission jamming; at the same time, the cooperation between the active wedge block 55 and the driven wedge block 590 converts the vertical movement of the lifting plate 52 into the lateral movement of the toothed plate 59, realizing the precise transmission of power and ensuring the smooth triggering of the thread tightening action; The guide tube 32 inside the central cylinder 31 is fixedly connected to the through port 203, which can provide vertical guidance for the male seat falling from the through port 203, prevent the male seat from deviating or tilting when falling, ensure that the male seat falls accurately between the multiple grippers 47 in the operating box 3, reduce clamping failure caused by misalignment of the male seat, improve feeding accuracy, and achieve the effect of accurate dropping of the male seat. The center of the control box 3 is fixedly installed with a central cylinder 31 connected to the transfer box 2. The inner cavity of the control box 3 is provided with a clamping part. A rotating rod 48 is rotatably installed on one side of the clamping part. A gear 480 located in the inner cavity of the control box 3 is fixedly installed on the outer side of the rotating rod 48. A drive part for controlling the rotation of the rotating rod 48 is slidably installed at the bottom of the control box 3.

[0022] First, the female connectors required for the electrical connector are clamped sequentially by the triangular chuck on 11. The male connectors required for the electrical connector are placed from 20 onto 202 directly below 20. As 201 rotates, multiple 202s rotate and reposition the male connectors placed in 20 sequentially. After the male connectors are rotated into 203, due to gravity, the male connectors in 203 fall into the clamping part. After the male connectors are clamped by the clamping part, the motor is turned on to drive 111 to rotate. When 111 rotates, it drives 10 to rotate. When 10 rotates, the female connectors clamped on multiple 11s are rotated sequentially to directly below 3, so that the male connectors in 3 can be continuously connected and installed with the female connectors that rotated below. When any of the female seats is directly below the operating box 3, the motor on the support plate 6 is turned on. The motor drives the extension rod 67 to rotate. When the extension rod 67 rotates, it drives the cam 68 to rotate. When the cam 68 rotates to press against the side frame 66, the side frame 66 drives the hollow frame 65 and the slide 62 to move downward after pressing the spring on the positioning post 61. When the slide 62 moves downward, it simultaneously drives the transfer box 2 and the operating box 3 to move downward. When the operating box 3 moves downward, it drives the male seat to engage with the female seat below. At the same time, when the slide 62 moves downward, the inner rod 112 also moves downward. At this time, the retaining strip 113 at the bottom of the inner rod 112 is in the retaining groove 114. As the operating box 3 moves downwards to engage with the female seat, the contact plate 51 on the operating box 3 contacts the bracket 11. The contact plate 51 then moves upwards due to the resistance force of the bracket 11. During this upward movement, the contact plate 51 simultaneously drives the lifting plate 52 to slide upwards within the operating box 3. As the lifting plate 52 slides upwards, it simultaneously drives the top component 53 and connecting rod 54 to move upwards. As the connecting rod 54 moves upwards, it drives the active wedge block 55 to move upwards, thereby pressing against the driven wedge block 590. The driven wedge block 590 moves towards the central cylinder 31. During this movement, the driven wedge block 59 simultaneously drives the toothed plate 59 to press against the spring on the crossbar 57. After sliding, when the toothed plate 59 moves, it drives the second gear 481 to rotate, which in turn drives the rotating rod 48 to rotate. When the rotating rod 48 rotates, it synchronously drives the first gear 480 to rotate. When the first gear 480 rotates, it drives the tensioning gear ring 4 to rotate. When the tensioning gear ring 4 rotates, it synchronously drives the male seat that is connected to the female seat to rotate. At this time, the male seat twists spirally inside the female seat, thereby completing the threaded fastening with the female seat. After the male seat and female seat are connected, the extension rod 67 rotates, driving the cam 68 to release the pressure on the side frame 66. Under the action of the spring outside the positioning column 61, it pushes the slide 62 to move upward along the positioning column 61 to reset. When 62 moves upward, it drives the operating box 3 to move upward, thereby canceling the clamping of the male seat. At the same time as the operating box 3 moves upward, the inner rod 112 also moves upward in the outer cylinder 111. By keeping the inner rod 112 and the operating box 3 rising and falling at the same time, the two pulleys 63 can always be in the same transmission plane. Then, the motor is turned on and drives the outer cylinder 111 to rotate. When the female seats clamped in the multiple brackets 11 on the turntable 10 are rotated to the position directly below the operating box 3, the transport frame 201 also rotates, causing the male seats in the multiple limiting slots 202 to rotate sequentially into the through port 203, thereby completing the continuous mating and docking operation between multiple male seats and multiple female seats. The lifting unit includes a positioning column 61 mounted on a support plate 6, a slide 62 slidably mounted on the positioning column 61, a spring sleeved on the outside of the positioning column 61 at the bottom of the slide 62, and a pressing part in the middle of the slide 62 to control the lifting of the slide 62 on the positioning column 61.

[0023] The extrusion section includes two symmetrically arranged hollow frames 65 mounted on the carriage 62. A side frame 66 is rotatably mounted between the two hollow frames 65. A cam 68 is in contact above the side frame 66. An extension rod 67 is fixedly mounted on one side of the cam 68. The extension rod 67 is rotatably connected to the support plate 6 via a motor.

[0024] An inner rod 112 is vertically slidably installed in the inner cavity of the outer cylinder 111. Multiple circumferentially arranged slots 114 are provided within the inner cavity of the outer cylinder 111. Each slot 114 contains a sliding retaining bar 113. The adjacent sides of the retaining bars 113 are fixedly connected to the inner rod 112. One side of the slide 62 is rotatably connected to the upper shaft of the transport frame 201, and the other side of the slide 62 is rotatably connected to the outside of the inner rod 112. Pulleys 63 are installed on both the upper end of the inner rod 112 and the upper shaft of the transport frame 201. A belt 6 is installed between two pulleys 63. 4. The sliding fit between the inner rod 112 and the outer cylinder 111, as well as the sliding of the retaining strip 113 in the retaining groove 114, can protect the internal transmission structure and prevent external impurities from entering and affecting the sliding and rotation effects. At the same time, the slide 62 is rotatably connected to the upper shaft of the transport frame 201 and the outer part of the inner rod 112, respectively. With the transmission of the two pulleys 63 and the belt 64, the rotation speed and work position of the outer cylinder 111, the turntable 10 and the transport frame 201 are synchronized, ensuring that the female seat changing and the male seat conveying are accurately synchronized, and further improving the coordination of continuous operation.

[0025] The clamping part includes a tensioning gear ring 4 located inside the operating box 3. An inner ring 41 is rotatably mounted on the inner side of the tensioning gear ring 4. Multiple connecting plates 42 are circumferentially mounted on the top of the inner ring 41. A gear ring 43 rotatably connected inside the operating box 3 is mounted between the multiple connecting plates 42. An electric push rod 49 is provided on one side of the gear ring 43. A stop block 490 is fixedly mounted on the telescopic end of the electric push rod 49. The electric push rod 49 on one side of the gear ring 43 cooperates with the stop block 490 to limit the rotation angle of the gear ring 43, thereby limiting the rotation range of the tensioning gear ring 4 and preventing the gripper 47 from excessively opening and closing, causing damage to the male seat or structural overload. At the same time, in conjunction with the related spring structure of the drive part, the gripper 47 can be driven to reset after clamping is completed, preparing for the next clamping of the male seat. When the electric push rod 49 is opened and pushed forward, it drives the stop block 490 to move towards the tension ring 4 until it stops the tension ring 4. When the tension ring 4 is rotating, the inner ring 41 and the tooth ring 43 remain relatively fixed. At this time, multiple arc grooves 44 squeeze the vertical rods 45 inside them respectively. The multiple vertical rods 45 drive the corresponding sliding frame 46 and the gripper 47 to move closer or further away from each other, so as to complete the clamping operation of the multiple grippers 47 on the male seat. In the clamping part, the arc-shaped groove 44 on the tensioning gear ring 4 slides with the vertical rod 45. When the tensioning gear ring 4 rotates, it can drive the vertical rod 45 to slide along the arc-shaped groove 44, thereby driving the sliding frame 46 to move synchronously and adjust the distance between the multiple jaws 47. This can not only adapt to clamping male seats of different specifications and sizes, but also avoid damage to the male seat due to excessive clamping or detachment due to excessive clamping by adjusting the clamping force.

[0026] The tensioning gear ring 4 has multiple circumferentially arranged arc-shaped grooves 44. Vertical rods 45 are slidably installed within these grooves. A sliding frame 46, located on the upper part of the connecting plate 42, is fixedly installed on the top of each vertical rod 45. Symmetrically arranged grippers 47 are fixedly installed on the sides of the multiple sliding frames 46 that are close to each other. Through the sliding engagement between the arc-shaped grooves 44 and the vertical rods 45, when the tensioning gear ring 4 rotates, it can drive multiple sets of grippers 47 to simultaneously retract or expand radially. Compared to traditional fixed-pitch grippers, this design can accommodate male connectors of different diameters and specifications within a certain size range, significantly improving the versatility of the device and eliminating the need for frequent mold changes for different models.

[0027] The drive unit includes a lifting plate 52 that passes through and slides in the control box 3. A contact plate 51 is fixedly installed at the bottom of the lifting plate 52. Symmetrical lifting rods 5 are provided on both sides of the upper end face of the contact plate 51. The lifting rods 5 pass through and slide along the side of the control box 3. A spring is also sleeved on the outside of the lifting rods 5 to abut against the contact plate 51. An L-shaped top component 53 is fixedly installed on one side of the top of the lifting plate 52. In the drive unit, the springs sleeved on the outside of the lifting rods 5 on both sides of the upper end face of the contact plate 51 can buffer the abutting force on the contact plate 51, avoiding structural wear caused by hard contact between the contact plate 51 and the card holder 11. At the same time, the elastic force of the spring can ensure that the contact plate 51 maintains its initial position when it is not subjected to abutting force, ensuring the stability of triggering the lifting plate 52, connecting rod 54, etc., and avoiding accidental triggering of the threaded fastening action.

[0028] The drive unit also includes a positioning frame 56 fixed to the operation box 3. A crossbar 57 is horizontally mounted on the positioning frame 56. A bent slide 58 set at a right angle is slidably mounted on the crossbar 57. A toothed plate 59 is fixedly mounted on one end of the bent slide 58. A gear 481 fixed to the top of the rotating rod 48 is meshed on the inner side of the toothed plate 59. A driven wedge block 590 is fixedly mounted on the side of the toothed plate 59 away from the gear 481. An active wedge block 55 is provided below the driven wedge block 590. The active wedge block 55 is fixedly connected to the top component 53 through a connecting rod 54.

[0029] The inner cavity of the central cylinder 31 is equipped with a guide tube 32, the upper end of which is fixed to the opening 203. The guide tube 32 facilitates the vertical drop of the male connector on the opening 203 into the multiple grippers 47. The central cylinder 31 not only connects the transfer box 2 and the operating box 3, but also protects the clamping and driving structures within the operating box 3, preventing debris and dust from entering during processing and affecting the stability of the grippers 47 and gear transmission. The enclosed structure of the transfer box 2 prevents the male connector from falling or shifting during transport, further ensuring the stability of loading and processing. The central cylinder 31, as the vertical connection channel between the transfer box 2 and the operating box 3, together with the internal guide tube 32, forms a closed vertical conveying space. This design effectively isolates dust, iron filings, and oil from the processing workshop from entering the grippers 47 and gear transmission mechanism inside the operating box 3, ensuring the lubrication and operational accuracy of the precision transmission pair and reducing equipment maintenance frequency.
