Description

Technical Field

[0001] This invention relates to the field of automated assembly equipment technology, and more specifically, to an automated assembly equipment for electrical connectors. Background Technology

[0002] Electrical connectors, as a fundamental and crucial electronic component, are widely used in various circuit boards, wire harnesses, and electronic devices to achieve stable connections and transmission of electrical signals. They are typically assembled from a base made of insulating material and conductive components such as hollow pins and springs made of metal. The base has sockets, while the hollow pins include connecting ends for crimping or soldering with wires, and insertion ends for securing them into the sockets of the base.

[0003] Currently, the process of assembling small components such as hollow pins into the base still largely relies on manual operation or semi-automatic equipment with low automation levels. Operators use simple tooling fixtures to fix the base, then hold the hollow pins and insert them into the sockets. This manual assembly method has significant drawbacks: First, it has low production efficiency, making it difficult to meet the needs of large-scale manufacturing; second, the inconsistent insertion depth and angle of the hollow pins easily lead to quality defects such as loose connections and insufficient insertion / removal force; third, the small size and large number of hollow pins make prolonged manual operation prone to visual fatigue, further affecting the stability of product quality.

[0004] Therefore, there is an urgent need in this field for a fully automated assembly equipment for electrical connectors that is highly automated, accurately positioned, capable of stably assembling multiple components such as hollow pins and even spring contacts, and can effectively prevent the base from shifting during the assembly process. Summary of the Invention

[0005] The present invention aims to provide an automated assembly equipment for electrical connectors, which realizes the precise and efficient insertion of hollow pins into the base during the fully automated assembly process of electrical connectors.

[0006] To achieve the above objectives, the present invention provides an automated assembly apparatus for an electrical connector, the electrical connector comprising a base having at least one socket and a hollow pin inserted into the socket, the hollow pin being configured such that a protruding portion of its portion exposed in the socket defines a mounting notch extending axially thereon; the automated assembly apparatus includes a frame, a turntable rotatably disposed on the frame, and a clamp positioned on the turntable, the clamp being adapted to hold the base; the automated assembly apparatus further includes a pin insertion mechanism, the pin insertion mechanism comprising: A support rod configured to extend along the axial direction of the socket; A push rod configured to move axially along the insertion hole to approach or move away from the base; and A driver configured to output linear motion to drive the push rod to produce axial movement; The front end of the push rod has a push-in portion that matches the mounting notch. The support rod is positioned below the push rod, and a positioning gap suitable for positioning the hollow pin is formed between the support rod and the push rod. The support rod and the push rod cooperate to move the hollow pin to the insertion hole, and the push rod pushes the hollow pin into the insertion hole by itself.

[0007] Furthermore, the support rod is configured to move axially along the insertion hole in a driven manner, such that, when the hollow pin is inserted, i. the distance between the front end face of the support rod and the outer end face of the insertion hole is less than 2 mm, or ii. the front end face of the support rod is inserted into the insertion hole.

[0008] By adopting the above technical solution, the relative position of the support rod and the outer end face of the socket can be precisely controlled. This ensures that the support rod stably supports the hollow pin during the pin insertion process and can cooperate with the socket at the appropriate time to guide and position the hollow pin for smooth insertion into the socket. This greatly improves the accuracy of pin and base insertion, avoids insertion failure or product damage caused by positional deviation, and improves assembly quality and product qualification rate.

[0009] Furthermore, the upper surface of the support rod is configured to be no lower than the lower edge of the socket, so that the hollow pin can be inserted into the socket along the upper surface of the support rod without being blocked by the lower edge of the socket.

[0010] By adopting the above technical solution, the obstruction of the lower edge of the socket to the insertion process of the hollow pin is eliminated, allowing the hollow pin to smoothly enter the socket under the guidance of the support rod. This reduces friction and resistance during the insertion process, which not only improves the insertion efficiency but also reduces the risk of deformation or damage to the hollow pin due to poor insertion, thus ensuring the stability and reliability of the electrical connector assembly process.

[0011] Furthermore, the support rod is connected to the driver via at least one elastic transmission member, which is configured to transmit a driving force to the support rod to move axially along the insertion hole, and to undergo elastic deformation when the front end of the support rod abuts against the base and is obstructed, so that the support rod stops at a predetermined position adjacent to the insertion hole.

[0012] By adopting the above technical solution and utilizing the elastic characteristics of the elastic transmission component, when the front end of the support rod is blocked by the base, the elastic transmission component undergoes elastic deformation to buffer the impact force, avoiding damage to the equipment and base caused by hard collision. At the same time, it allows the support rod to accurately stop at the predetermined position, providing a stable and reliable position reference for the subsequent push rod to accurately push the hollow pin into the socket. This reflects the flexibility and intelligence of the equipment design and effectively improves the fault tolerance and stability of the assembly process.

[0013] Furthermore, when the support rod is obstructed and stops at the predetermined position, the driver continues to drive the push rod to move axially and push the hollow pin into the socket of the base.

[0014] By adopting the above technical solution, a clever coordination and division of labor between the support rod and the push rod is achieved. The support rod first reaches the predetermined position to complete the initial positioning and support of the hollow pin, and then the push rod independently completes the pin pushing action under the continuous drive of the driver. This step-by-step and coordinated working method ensures the accuracy and efficiency of the pin insertion process, avoids the interference and errors that may be caused by the simultaneous action of the two rods, and further improves the performance and reliability of the automated assembly equipment.

[0015] Furthermore, the push rod includes an abutment portion extending along the length direction of the push rod, the abutment portion abutting against the support rod, and the abutment portion having an abutment surface for abutting against the end face of the hollow pin on one side within the positioning gap.

[0016] By adopting the above technical solution, the abutting part of the push rod and the supporting rod abut against each other, forming a stable structural relationship. At the same time, the abutting surface precisely abuts against the end face of the hollow pin, providing a stable and uniform pushing force to the hollow pin. This design ensures that the hollow pin is subjected to uniform force during the pushing process, and will not shift or tilt due to uneven force, thereby ensuring that the hollow pin can be accurately inserted into the base socket, greatly improving the accuracy and success rate of insertion, and reflecting the refinement and innovation of the equipment design.

[0017] Furthermore, the electrical connector further includes a spring contact, the base is provided with a slot that mates with the spring contact, and the insertion mechanism further includes a spring contact insertion mechanism, which includes: A push rod, capable of linear motion relative to the clamp, moves closer to or further away from the clamp to push the spring piece into the slot; and A spring conveying track is used to convey and position the spring in a set posture to the end of the push rod; The length direction of the push rod is aligned with the length direction of the slot, and the push rod is configured to push the spring into the slot in its forward path.

[0018] By adopting the above technical solution, the hollow pin assembly and spring assembly functions are integrated into the same equipment. Through shared fixtures and coordinated actions, the automated one-stop assembly of the core components of the electrical connector is realized, which greatly reduces the material flow, repetitive positioning and equipment occupation between processes, and significantly improves the overall production efficiency.

[0019] Furthermore, the spring insert mechanism also includes a rotating rod disposed at the end of the spring conveying track and capable of unidirectional rotation. The rotating rod is configured to be non-rotatable in the direction in which the spring is inserted into the slot to apply a certain resistance to the spring, and to be freely rotatable in the opposite direction.

[0020] By adopting the above technical solution, the unidirectional rotating rod constitutes a clever unidirectional limiting mechanism. It provides resistance in the direction of spring insertion, ensuring that the spring can be stably stopped in the preparatory position before being pushed by the push rod, without falling or excessive forward movement; and when it is necessary to replenish or replace the spring, it can be easily filled in from the opposite direction, realizing stable "forward-backward" conveying.

[0021] Furthermore, the spring conveying track also includes a baffle for defining the end of the spring so that the spring is positioned at the end of the push rod.

[0022] By adopting the above technical solution, the baffle provides a precise mechanical limit for the conveying direction of the spring sheet. Working together with the rotating rod, it ensures that each spring sheet can be accurately conveyed to a fixed position in front of the push rod, laying a solid foundation for the push rod to perform stable and reliable insertion actions.

[0023] Furthermore, the fixture is also provided with a clearance groove that allows the shrapnel to pass through.

[0024] By adopting the above technical solution, the clearance groove provides an unobstructed insertion channel for the spring, allowing the push rod to directly and completely push the spring into the slot of the base located in the fixture, avoiding interference of the fixture itself with the assembly process and ensuring the smooth progress of the assembly action.

[0025] Furthermore, the two side walls of the clearance groove are connected with protruding ribs, which are configured to be located within the slot when the base is fixed by the clamp, so as to restrict the rotation of the base.

[0026] By adopting the above technical solution, the rib structure achieves an integrated design of anti-rotation and obstacle avoidance functions. When the base is fixed, the rib fits precisely into the slot of the base, forming an effective circumferential limit. This is a preferred solution that is parallel to or alternative to the slider anti-rotation, further enhancing the adaptability of the equipment to bases with different structures.

[0027] In summary, this application has at least one of the following beneficial technical effects: 1. Achieves high precision and high reliability in insertion: Through the precise positioning of the transmission mechanism, the surface contact between the push rod and the hollow pin, and the combined action of the support rod and the positioning gap, the hollow pin is ensured to be inserted without deflection or jamming, significantly improving the insertion success rate and product consistency.

[0028] 2. It has the capability of assembling multiple components in one piece: By integrating the spring insert mechanism and equipping it with positioning mechanisms such as baffles, the precise assembly of multiple components such as hollow pins and springs can be completed automatically on one machine, which greatly improves production efficiency and simplifies the production process.

[0029] 3. Multiple effective anti-rotation protections are provided: Through the mating of the slider and blind hole, and the engagement of the relief groove rib and slot, etc., the base is ensured to be firmly locked during the assembly process, which fundamentally solves the assembly accuracy problem caused by base displacement or rotation, and ensures the quality of the final product.

[0036] The technical solutions of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0037] Please see Figure 1 and Figure 2 The electrical connector 1 involved in this embodiment mainly consists of three parts: a base 11, a hollow pin 12, and a spring contact 13. The base 11 serves as the basic support structure for the entire connector and has a socket 112. The size, shape, and position of the socket 112 are precisely designed to ensure accurate mating with the hollow pin 12 to be inserted later. The hollow pin 12 includes a connecting end and a plugging end. The connecting end has an installation notch 121, which plays a crucial role in the assembly process. It is not only the part that directly contacts the assembly equipment but also an important interface ensuring a stable connection between the hollow pin 12 and the base 11. The plugging end is responsible for plugging and fixing with the socket 112 on the base 11. Its shape and size are strictly adapted to the socket 112 to achieve reliable electrical connection and mechanical fixation. The spring 13, as an elastic element in the electrical connector 1, plays multiple roles in circuit connection, such as buffering and conductivity. It cooperates with the slot 113 on the base 11 to complete the transmission and connection of electronic signals. The outer side of the base 11 has a blind hole 111 facing inward. This design provides a key structure for positioning and fixing in the subsequent assembly process.

[0038] Please see Figures 3-9 This embodiment discloses an assembly device for assembling the above-mentioned electrical connector 1. The main function of the device is to accurately insert the hollow pin 12 into the socket 112 of the base 11.

[0039] Please see Figure 3 The assembly equipment includes a frame and a rotatable turntable 7. The turntable 7 is equipped with a clamp 2 for fixing the base 11 of the electrical connector 1. A pin insertion mechanism 3 and a spring insertion mechanism 6 are arranged on the outer periphery of the turntable 7. The pin insertion mechanism 3 is connected to a transmission mechanism 4. A vibratory feeder 5 sequentially conveys hollow pins 12 in the same direction to the transmission mechanism 4. The transmission mechanism 4 delivers the hollow pins 12 one by one to the insertion station of the pin insertion mechanism 3 so that the hollow pins 12 can be inserted into the base 11 within the clamp 2.

[0040] Please see Figure 4 and Figure 5The fixture 2 in the assembly equipment is an important component for fixing the base 11. It includes an upper mold 21 and a lower mold 22. When the upper mold 21 and the lower mold 22 are engaged, they form a fixing cavity 24. The shape and size of the fixing cavity 24 match the shape of the base 11, which can well accommodate and clamp the base 11, ensuring that the base 11 maintains a stable posture during assembly. A slider 23 is slidably connected to the fixture 2. The end of the slider 23 is provided with a mating surface 231. When the base 11 is accurately placed in the fixing cavity 24 of the fixture 2, the slider 23 can achieve a tight fit with the blind hole 111 on the outer side of the base 11 (see reference). Figure 1 This mating method effectively restricts the rotation of the base 11 during assembly, ensuring the accuracy and stability of the hollow pin insertion operation. To ensure that the slider 23 always maintains its mating state with the blind hole 111, the slider 23 is also connected to an elastic element via a connecting rod 25. This elastic element has a restoring force that keeps the slider 23 facing the fixed cavity 24, ensuring that the slider 23 aligns with the blind hole 111 promptly and accurately (see...). Figure 1 This provides reliable positioning and fixation for the entire assembly process.

[0041] Please see Figure 5 The clamp 2 is also provided with a clearance groove 221 that allows the spring clip 13 to pass through. The design of the clearance groove 221 not only provides the necessary space for the insertion of the spring clip 13, but also further optimizes the assembly process. The two side walls of the clearance groove 221 are connected with protruding ribs 222. When the base 11 is fixed by the clamp 2, the protruding ribs 222 can be accurately located in the slot 113. This structure further restricts the rotation of the base 11 during the assembly process. Together with the previous cooperation between the slider 23 and the blind hole 111, it constitutes a dual positioning and fixing mechanism (see Figure 1 This greatly improves the stability and reliability of the assembly process, ensuring the quality and efficiency of electrical connector assembly.

[0042] Please see Figures 6-9 The pin insertion mechanism 3 is one of the core components of the assembly equipment. It includes a transmission mechanism 4 and a push rod 31 capable of linear movement toward or away from the clamp 2. The end of the push rod 31 is carefully provided with a push portion 311 that adapts to the mounting notch 121 of the hollow pin 12 (see reference). Figure 2This design allows the push rod 31 to seamlessly engage with the hollow pin 12 during movement. The pin insertion mechanism 3 also includes a support rod 32 located below the push rod 31. A positioning gap 33 is formed between the support rod 32 and the push-in portion 311 of the push rod 31 to accommodate and limit the side wall of the hollow pin 12. The existence of this positioning gap 33 ensures that the hollow pin 12 will not shift or wobble during insertion, thereby guaranteeing the accuracy and quality of insertion. To facilitate the smooth entry of the hollow pin 12 into the base 11, the support rod 32 has a guide surface 321 on the side away from the push rod 31. The guide surface 321 is a bevel or arc surface to facilitate contact with the insertion hole 112, and can guide the hollow pin 12 to be accurately inserted into the insertion hole 112 of the base 11 along the upper surface of the support rod 32 (see...). Figure 2 This reduces assembly failures caused by positional deviations of the hollow pin 12.

[0043] The support rod 32 is configured to be driven to move axially along the insertion hole 112 so that, when the hollow pin 12 is inserted, i. the distance between the front end face of the support rod 32 and the outer end face of the insertion hole 112 is less than 2 mm, or ii. the front end face of the support rod 32 is inserted into the insertion hole 112. The upper surface of the support rod 32 is configured to be no lower than the lower edge of the insertion hole 112 so that the hollow pin 12 can be inserted into the insertion hole 112 along the upper surface of the support rod 32 without being obstructed by the lower edge of the insertion hole 112.

[0044] The transmission mechanism 4 also plays a crucial role in the assembly process. It is responsible for conveying and positioning the hollow pin 12 in a preset posture in front of the push rod 31, ensuring precise alignment between the mounting notch 121 of the hollow pin 12 and the push-in portion 311 of the push rod 31. This precise alignment is a key prerequisite for ensuring that the hollow pin 12 can be smoothly pushed by the push rod 31 and inserted into the socket 112 of the base 11. When the push rod 31 moves towards the clamp 2, the push-in portion 311 can smoothly and forcefully push the hollow pin 12 through the mounting notch 121, accurately inserting it into the socket 112 of the base 11 fixed by the clamp 2, thus completing the assembly process of the hollow pin 12 and the base 11 (see...). Figure 2 ).

[0045] Please see Figure 9 and Figure 10The support rod 32 is connected to the driver via at least one elastic transmission member 36. The driver drives the push rod 31 to slide via the rear slide plate 35. The support rod 32 is fixedly connected to the front slide plate 34, and the elastic transmission member 36 is disposed between the front slide plate 34 and the rear slide plate 35. While the driver drives the push rod 31 to slide via the rear slide plate 35, the rear slide plate 35 pushes the front slide plate 34 via the elastic transmission member 36, causing the support rod 32 to slide synchronously. The elastic transmission member 36 is configured to transmit a driving force to the support rod 32 to move axially along the insertion hole 112, and to undergo elastic deformation when the front end of the support rod 32 abuts against the base 11 and is obstructed, so that the support rod 32 stops at a predetermined position adjacent to the insertion hole 112. When the support rod 32 is obstructed and stops at the predetermined position, the driver continues to drive the push rod 31 to move axially and push the hollow pin 12 into the insertion hole 112 of the base 11.

[0046] Please see Figure 3 , Figure 11 , Figure 12 and Figure 13 In some more refined embodiments, the insertion mechanism is further enhanced by a spring insert mechanism 6. This component further enriches the functionality of the assembly equipment, enabling automated assembly of the spring 13 and the base 11. The spring insert mechanism 6 mainly includes a push rod 61 and a spring conveying track 62. The push rod 61 can move linearly closer to or further away from the clamp 2, and its main function is to accurately push the spring 13 into the slot on the base 11. The spring conveying track 62 is responsible for conveying the spring 13 according to a set posture and positioning it at the end of the push rod 61, ensuring that the push rod 61 can smoothly push the spring 13 during movement. The length direction of the push rod 61 is aligned with the length direction of the slot 113. This precise alignment ensures that the push rod 61 can accurately push the spring 13 into the slot 113 during its forward path, avoiding assembly problems caused by directional deviation (see...). Figure 2 ).

[0047] Please see Figure 11 To better control the movement of the spring piece 13 during insertion, the spring piece insertion mechanism 6 also includes a unidirectional rotating rod 63 located at the end of the spring piece conveying track 62. The rotating rod 63 is configured to be non-rotatable in the direction in which the spring piece 13 inserts into the slot 113, thereby applying a certain resistance to the spring piece 13. This resistance ensures that the spring piece 13 maintains a stable posture during insertion, avoiding problems such as deformation or incomplete insertion due to excessive insertion speed or uneven force. Conversely, the rotating rod 63 can rotate freely in the opposite direction, facilitating the removal of the spring piece 13 after assembly or other subsequent operations.

[0048] Please see Figure 12 and Figure 13The spring conveying track 62 is also equipped with a baffle 64. The main function of the baffle 64 is to limit the end of the spring 13, so that the spring 13 can be accurately positioned to the end of the push rod 61, providing a precise positioning guarantee for the push rod 61 to push the spring 13.

[0049] In summary, the automated assembly equipment for electrical connectors disclosed in this embodiment, through careful structural design and ingenious working principle, achieves efficient and precise assembly of electrical connectors, providing reliable technical support for the large-scale production of electrical connectors.
