Description

Technical Field

[0001] This utility model relates to the field of automotive massage seat technology, and more specifically, to a terminal block positioning device and assembly equipment. Background Technology

[0002] Terminal blocks are fundamental components widely used in electrical connections, typically consisting of a base, conductive inner core, spring, and pin. The most crucial and challenging step in assembling these terminals is precisely threading the pin through the elongated hole in the base and the pin hole in the inner core. Because the inner core is spring-supported and freely rotating after being inserted into the base, its pin hole is obscured by the base and cannot be directly observed. Operators must rely on experience and subtle tactile adjustments to repeatedly fine-tune the circumferential angle of the inner core, attempting to align the hidden pin hole with the visible elongated hole on the outer side of the base. This process has the following significant drawbacks: 1. Low assembly efficiency: It relies entirely on manual exploration and debugging by operators. The alignment process is time-consuming and labor-intensive, making it difficult to achieve rapid and continuous mass production, which becomes a bottleneck in the entire production process.

[0003] 2. Difficulty in guaranteeing product qualification rate: The instability of manual operation can easily lead to misalignment. If the pin is forced in before the pin hole is fully aligned, it can easily cause damage to the pin, inner core, or base structure, resulting in defective products.

[0004] 3. Difficulty in achieving automation: Due to the lack of reliable methods for locating the inner core angle, traditional automated feeding and assembly mechanisms such as vibratory feeders and standard robotic arms are difficult to apply directly, which restricts the improvement of the automation and intelligence level of the production line.

[0005] In existing technologies, there are some solutions that attempt to use specialized fixtures for assisted positioning. However, these solutions are often limited in function, typically only solving the problem of clamping a single type of terminal or positioning in a certain direction. Furthermore, they are difficult to be compatible with the different positioning and driving requirements of different stages in the assembly process (such as base fixing, inner core angle correction, and pin insertion), lacking versatility and flexibility. Utility Model Content

[0006] The present invention aims to provide a positioning device and assembly equipment for terminal blocks to improve assembly efficiency and pass rate.

[0007] To achieve the above objectives, in a first aspect, this utility model provides a terminal block positioning device for positioning and fixing components during terminal block assembly, thereby improving the convenience and accuracy of assembly operations. The terminal block includes a base, an inner core, a spring, and a pin. The base has an inner cavity, an axially extending elongated hole, and a first wiring hole. The inner core has a pin hole and a second wiring hole and is assembled in the inner cavity of the base. The spring is placed in the inner cavity, with its two ends abutting against the base and the inner core, respectively. The pin passes sequentially through the elongated hole of the base and the pin hole of the inner core, forming an axial sliding connection between the inner core and the base. The positioning device includes: Base; A clamp, slidably connected to the base, is used to clamp and fix the base; and A positioning component is used to ensure that the pin hole of the inner core is aligned with the elongated hole of the base during assembly, so that the pin can be smoothly inserted; the positioning component further includes: A positioning block, slidably connected to the base, is used to engage with the elongated hole and to define the circumferential position of the base by the shape and position of the elongated hole; The positioning pin is slidably connected to the base or positioning block and is used to pass through the elongated hole of the base and insert into the pin hole of the inner core after the inner core is placed into the inner cavity of the base, so that the direction of the pin hole is aligned with the elongated hole. The positioning block and positioning pin can be driven synchronously or independently, thereby adapting to the positioning requirements of different processes during assembly and enhancing the functional compatibility and operational flexibility of the positioning device.

[0008] By adopting the above technical solutions, a highly flexible and intelligent positioning system is constructed. Its selectable "synchronous / independent" drive mode allows the device to be perfectly compatible with different stages of the assembly process: for example, it can be driven synchronously to quickly complete initial positioning, or driven independently for step-by-step fine-tuning under complex working conditions. This dynamic adaptability greatly enhances the device's functional compatibility and process adaptability, laying a core foundation for building highly flexible automated production lines.

[0009] In some embodiments, the positioning block includes a first positioning part and a second positioning part, wherein the first positioning part is used to limit the circumferential direction of the base, and the second positioning part is used to limit the axial direction of the base.

[0010] By adopting the above technical solution, a single composite positioning block simultaneously achieves coordinated constraints on two key degrees of freedom (circumferential and axial) of the base. This integrated design replaces the traditional positioning task that requires multiple independent components and drive sources, not only simplifying the mechanical structure and reducing manufacturing costs and control complexity, but also fundamentally eliminating the cumulative errors that may occur in step-by-step positioning, significantly improving the systematic accuracy and overall efficiency of positioning.

[0011] In some embodiments, the first positioning part and the second positioning part are fixedly connected or integrally formed so as to simultaneously limit the circumferential and axial positioning of the base when the positioning block slides.

[0012] By adopting the above technical solution, the two positioning parts are integrated into a rigid motion unit, which can achieve synchronous and precise positioning of two degrees of freedom through a single linear drive. This structure ensures the absolute synchronization of the determination of circumferential angle and axial position, completely avoiding the risk of part displacement or loss of positioning reference caused by time-sharing or step-by-step operation, thus ensuring the high consistency and reliability of each positioning action.

[0013] In some embodiments, a guiding component is also included, comprising a guide pin slidable relative to the base, the guide pin being disposed opposite to the positioning pin on both sides of the clamp.

[0014] By adopting the above technical solution, a balanced positioning force system is constructed, applying forces from both sides of the workpiece. This opposing arrangement uses guide pins to coarsely position the inner core, and then uses positioning pins to accurately position the inner core, providing a precise geometric channel for the smooth passage of the pin shaft in subsequent processes.

[0015] In some embodiments, the positioning component further includes a third positioning part disposed on the base for resisting the elastic force of the spring and axially abutting the inner core to define the axial position of the inner core.

[0016] By adopting the above technical solution, the preload force of the spring is actively overcome and utilized. Instead of passively adapting to the floating of the inner core, it actively presses and stabilizes it on a preset axial coordinate. This provides a stable and reliable target for the insertion of the locating pin and prevents the inner core from accidentally popping out due to spring force during subsequent operations, greatly improving the safety and controllability of the entire assembly process.

[0017] Secondly, this application provides a terminal block assembly device, including the terminal block positioning device of the first aspect.

[0018] By adopting the above technical solution, the aforementioned modular, high-precision dedicated positioning device is integrated into the assembly equipment as a core functional unit, achieving a systematic integration of the positioning function with other process modules such as loading / unloading and riveting. This integrated design automates and automates the entire assembly process, significantly improving production cycle time and product consistency, while reducing reliance on operator skills.

[0019] In some embodiments, a core feeding device is also included for placing the core into the base, the core feeding device comprising: A clamping assembly for clamping the inner core and placing it into the inner cavity of the base; A detection component for detecting the circumferential position of the inner core before it is placed into the inner cavity of the base; The clamping assembly first adjusts the axial direction of the inner core to be consistent with the axial direction of the base after clamping the inner core, then rotates the inner core. When a confirmation signal is received from the detection assembly, the rotation stops and the core is placed into the inner cavity of the base until the orientation of the pin hole is aligned with the length direction of the elongated hole.

[0020] By adopting the above technical solution, the most difficult problem of blind alignment of the inner cavity is transformed into an externally visualized "pre-alignment" operation. Before insertion, the inner core is adjusted to the correct angle within the open space using a detection and rotation mechanism, ensuring from the outset that the relative angle between the inner core and the base is close to the target state after insertion. This significantly reduces the workload and correction stroke of subsequent positioning components, making it a key upstream process for improving the overall system efficiency and first-time success rate.

[0021] In some embodiments, a riveting device is also included, comprising a riveting head that can slide relative to the base, wherein when the riveting head abuts against the pin and passes the pin through the pin hole, the pin pushes the locating pin out of the pin hole.

[0022] By adopting the above technical solution, an ingenious "functional relay" mechanism was designed. Utilizing the forward momentum of the assembly component (pin), the positioning tool (positioning pin) that has completed its guiding mission is automatically and accurately ejected from the narrow assembly space. This process requires no additional drive or control, achieving seamless handover and automatic retraction between the tool and the workpiece, simplifying the mechanical structure, avoiding spatial interference, and is the core design for achieving efficient, smooth, and continuous automated assembly.

[0023] In some embodiments, the pin is restricted from sliding after being pushed out of the pin hole by a predetermined distance, thereby defining the pin assembly position.

[0024] By adopting the above technical solution, the final assembly position of the pin is precisely mechanically positioned using a hard limit mechanism. This ensures the consistency of the pin's extension length or press-in depth across all products, a core measure for controlling key product dimensions and quality. It effectively avoids product malfunctions (such as poor sliding or loose connections) caused by excessively deep or shallow assembly, ensuring the reliability and uniformity of the final product's performance.

[0025] In some embodiments, a base feeding device is also included, which includes a base conveying assembly, a limiting assembly, and a base clamping assembly, wherein the limiting assembly is configured to convey bases one by one to the position of the base clamping assembly.

[0026] In summary, this application has at least one of the following beneficial technical effects: 1. Achieved high-precision, high-success-rate automated assembly: Through the coordination of positioning blocks and positioning pins, and the pre-alignment of the inner core feeding device, the industry bottleneck of difficult alignment of hidden pin holes was systematically solved, and the assembly process was transformed from an uncertain operation that relied on manual feel to a precise and repeatable process guaranteed by equipment, which significantly improved the product qualification rate.

[0027] 2. A highly flexible and efficient production process has been constructed: the core positioning element has a selectable drive mode of "synchronous / independent", and the ingenious connection and automated collaboration of various functional modules (such as material picking, positioning, and riveting) enable the entire assembly equipment to adapt to high-speed, continuous batch production, greatly improve production efficiency, and have good process adaptability.

[0028] 3. The ingenious mechanical design ensures the reliability and safety of the process: designs such as the automatic ejection of the positioning pin, the third positioning part to counteract the spring force, and the hard limit of the pin assembly not only simplify the structure and control, but also proactively prevent common quality problems and safety risks such as jamming, parts splashing, and excessive assembly, thus ensuring the safety of equipment and personnel, as well as the stability of long-term operation.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0035] 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.

[0036] Example 1 Please see Figures 3-7 This embodiment provides a terminal block 100 positioning device 200, which is used to position and fix components during the assembly process of the terminal block 100, so as to improve the convenience and accuracy of the assembly operation.

[0037] Please see Figure 1 and Figure 2 The terminal block 100 includes a base 11, an inner core 12, a spring 14, and a pin 13. The base 11 has an inner cavity, an elongated hole 112 extending axially therefrom, and a first wiring hole 111. The inner core 12 has a pin hole 122 and a second wiring hole 121, and is fitted into the inner cavity of the base 11. The spring 14 is placed within the inner cavity, with its two ends abutting against the base 11 and the inner core 12 respectively, providing a restoring elastic force for the inner core 12. The pin 13 passes sequentially through the elongated hole 112 of the base 11 and the pin hole 122 of the inner core 12, sliding within the elongated hole 112, thereby connecting the inner core 12 and the base 11 to form the intended axial sliding connection.

[0038] Press down the inner core 12 to align the first wiring hole 111 and the second wiring hole 121, pass the wire through the first wiring hole 111 and the second wiring hole 121, release the inner core 12, and under the elastic force of the spring 14, the inner core 12 and the base 11 clamp and fix the wire, thus achieving connection.

[0039] See Figure 3 The positioning device 200 in this embodiment mainly includes a positioning fixture 21 and a guiding component 22, and the wiring terminal 100 is disposed in the positioning fixture 21 and clamped and fixed.

[0040] Please see Figures 4-6 The positioning fixture 21 includes a base 211, a clamp 212, and a positioning assembly. The base 211 serves as the mounting base and support frame for the positioning assembly. The clamp 212 is slidably connected to the base 211 via two jaws or similar structures. A cavity matching the shape of the base 11 can be formed between the two jaws to reliably clamp and fix the base 11 during assembly.

[0041] The positioning component is the core of this device. It is used to actively ensure that the pin hole 122 of the inner core 12 is precisely aligned with the elongated hole 112 of the base 11 during the assembly process, thus creating conditions for the smooth insertion of the pin 13. The positioning component includes a positioning block 214 and a positioning pin 2141.

[0042] The positioning block 214 is provided with a sliding groove 2144, and the base 211 is provided with a sliding shaft 216. The sliding shaft 216 connects the base 211 and the positioning block 214, and can slide relative to each other within the sliding groove 2144. The positioning block 214 is driven by a first drive source (such as a cylinder 222 or an electric cylinder) to slide relative to the base 211. The front end of the positioning block 214 is designed with a specific profile for engaging with the elongated hole 112 on one side of the base 11. When the positioning block 214 moves forward and engages with the elongated hole 112, it completes the circumferential positioning of the base 11, preventing it from rotating in the clamp 212.

[0043] The positioning pin 2141 is used for precise positioning of the inner core 12. The positioning pin 2141 passes through the positioning block 214 and forms a sliding connection with the positioning block 214 (in another embodiment, the positioning pin 2141 may be slidably connected to the base 211), and is driven by a first drive source or a second drive source. After the inner core 12 is placed into the base 11, the positioning pin 2141 can move forward in a controlled manner, its front end precisely inserting into the pin hole 122 of the inner core 12. This action directly corrects the circumferential angle of the inner core 12, aligning the axial direction of the pin hole 122 with the elongated hole 112.

[0044] Specifically, the positioning block 214 and the positioning pin 2141 can be driven synchronously by a coordinated drive mechanism to achieve rapid initial positioning; or they can be driven separately by their own independent drive sources to adapt to step-by-step fine-tuning under complex working conditions. This flexible drive mode greatly enhances the functional compatibility and operational flexibility of the device, and can adapt to different assembly process cycles and precision requirements.

[0045] Please see Figure 5 and Figure 6 Furthermore, the positioning block 214 can be designed as a composite structure including a first positioning part 2142 and a second positioning part 2143. The first positioning part 2142 is the part mentioned above used to engage with the elongated hole 112 and perform circumferential positioning. The second positioning part 2143 is a boss fixedly connected to the first positioning part 2142. When the positioning block 214 moves forward into position, the second positioning part 2143 can abut against the end face or a specific step of the base 11, thereby simultaneously limiting the axial position of the base 11.

[0046] In this embodiment, the first positioning part 2142 and the second positioning part 2143 are integrally formed on the positioning block 214. This allows the circumferential and axial positioning of the base 11 to be completed simultaneously in one sliding stroke of the positioning block 214, simplifying the parts and actions, and improving positioning efficiency and accuracy.

[0047] In addition, the positioning assembly also includes a third positioning part 213 disposed on the base 211. This third positioning part 213 is a stop fixed to the positioning block 214. Its function is to resist the spring force of the spring 14 and axially abut against the inner core 12 from above after the inner core 12 is inserted into the base 11, stabilizing it in a preset axial position and preventing it from loosening or popping out, thus providing a stable and reliable target for the subsequent insertion of the positioning pin 2141. In another embodiment, the third positioning part 213 can be slidably connected to the base 211 and driven by a third drive source to achieve independent operation and meet more operational needs.

[0048] Please see Figure 2 , Figure 3 and Figure 7 When the inner core 12 is placed into the base 11, there will be a slight angle deflection. To ensure the accuracy of the position between the inner core 12 and the base 11, this device also includes a guide assembly 22. The guide assembly 22 includes a guide pin 221 that can slide relative to the base 211. The guide pin 221 and the aforementioned positioning pin 2141 are disposed on both sides of the clamp 212. When the inner core 12 needs to be pressed, the guide pin 221 is inserted into the pin hole 122 under the drive of the cylinder 222. The head of the guide pin 221 is tapered, which can guide the pin hole 122. Then, the positioning pin 2141 moves towards the pin hole 122 and inserts into the pin hole 122, clamping or guiding the inner core 12 from both sides, ensuring that the pin shaft 13 can pass smoothly through the elongated hole 112 and the pin hole 122, and be smoothly inserted into the position to achieve reliable positioning.

[0049] Example 2 Please see Figure 2 , Figure 5 as well as Figures 8-13 This embodiment provides a terminal block 100 assembly device, which includes the terminal block 100 positioning device 200 described in Embodiment 1, thereby possessing high-precision positioning capability.

[0050] Based on this, the equipment also integrates a base feeding device 300 for placing the base 11 into the positioning fixture 21, a spring feeding device 400 for placing the spring 14 into the base 11, an inner core feeding device 500 for automatically placing the inner core 12 into the base 11, a pin feeding device 600 for inserting the pin 13 into the terminal block 100, and a riveting device 700 for pressing the pin 13 into a set position.

[0051] Please see Figure 9 The base feeding device 300 includes a base conveying assembly 31, a limiting assembly 32, and a base clamping assembly 33. To improve placement accuracy, it also includes a detection assembly (not shown in the figure), which is a photoelectric element. The base conveying assembly 31 sequentially conveys the bases 11 to the limiting assembly 32. The limiting assembly 32 conveys the bases 11 one by one to the position of the base clamping assembly 33. The base clamping assembly 33 clamps the base 11 and rotates. When the detection assembly detects that the orientation and position of the base 11 are correct, the base clamping assembly 33 stops rotating and places the base 11 into the positioning fixture 21.

[0052] Specifically, the detection component identifies the circumferential features of the base 11 using a non-contact detection method to determine whether its orientation is correct. In practical applications, any of the following implementation methods or combinations thereof can be used: Please see Figure 2 The detection scheme based on the elongated aperture 112 involves precisely arranging a set of through-beam photoelectric sensors on both radially sides of the rotation path of the base 11, ensuring that the beam propagation path passes precisely through the ideal rotation trajectory of the base 11. When the base 11 rotates, if its elongated aperture 112 rotates to a specific angle parallel to the beam, the beam will be able to penetrate the elongated aperture 112 and be detected by the receiver on the opposite side, thereby generating a characteristic pulse signal. When the control system recognizes this signal, it can determine that the base 11 has rotated to the target angle.

[0053] The detection scheme based on the first wiring hole 111 involves using a diffuse reflection photoelectric sensor or a vision sensor, aligned with the area where the first wiring hole 111 is located on the base 11. When the base 11 rotates, causing the opening or internal reflective surface of the first wiring hole 111 to enter the sensor's detection field of view, the sensor will detect a reflection signal characteristic different from that of the physical part. By identifying the point of change of this characteristic signal, the control system can accurately determine whether the base 11 has reached the preset circumferential position.

[0054] Please see Figure 10 The inner core feeding device 500 mainly includes an inner core conveying assembly 51, an inner core gripping assembly 52, and a detection assembly. The inner core conveying assembly 51 transports the inner cores 12 in a uniform orientation to the gripping assembly station. The gripping assembly, using a pneumatic finger or servo-driven gripper, grips the inner cores 12 from the feeding area and transfers and places them into the inner cavity of the base 11. The detection assembly, using a vision camera, fiber optic sensor, or proximity switch, is arranged along the picking path to detect the circumferential position of the inner core 12 in real time before it is placed into the inner cavity of the base 11. Specifically, it identifies the orientation of its pin hole 122; for details, please refer to the principle of the detection assembly in the base 11.

[0055] The workflow is as follows: After the gripping assembly grips the inner core 12, it first adjusts the axial direction of the inner core 12 to align it with the axial direction of the base 11. Then, the gripping assembly (which typically has its own rotation function) begins to rotate the gripped inner core 12. During this process, the detection assembly continuously monitors the circumferential angle of the inner core 12. When it detects that the pin hole 122 of the inner core 12 is aligned with the target angle (i.e., aligned with the length direction of the elongated hole 112 on the base 11), it immediately sends a confirmation signal. Upon receiving this signal, the gripping assembly stops rotating and then performs a lowering action, precisely placing the inner core 12 into the inner cavity of the base 11. This "pre-alignment" process significantly improves the alignment success rate of the inner core 12 after its first placement.

[0056] Example 3 This embodiment further integrates a riveting device 700 based on the assembly equipment provided in Embodiment 2.

[0057] Please see Figures 11-13 The riveting device 700 includes a riveting head 71 and a pushing assembly 72. The riveting head 71 can be driven by the same driving source through a linkage mechanism, or it can be driven by independent driving sources to realize the riveting of the wiring terminal 100 inside the positioning fixture 21.

[0058] Please see Figure 13 Before the riveting joint 71 is activated, both the pin 13 and the locating pin 2141 are partially inserted into the inner core 12 to position both ends of the inner core 12, reducing the chance of the inner core 12 rotating or deviating. After the riveting joint 71 is activated, the pin 13 is pushed into the inner core 12 while the locating pin 2141 is pushed out of the inner core 12. The locating pin 2141 can be equipped with a limiting structure to limit the movement distance of the locating pin 2141. When the locating pin 2141 retracts to a set distance, the locating pin 2141 cannot move backward, thus limiting the movement of the pin 13 and ensuring the consistency of the position of the pin 13 in the inner core 12. At the same time, the rivet joint 71 can also be used to rivet the pin 13, reducing the risk of the pin 13 coming out.

[0059] The working process is as follows: When it is necessary to assemble the pin 13, the riveting head 71 advances, abuts against the end of the pin 13 pre-installed in the inner core 12, and presses it in. As the pin 13 passes through the pin hole 122 of the inner core 12 under the drive of the riveting head 71, the advancing pin 13 will contact the end of the positioning pin 2141 located on the other side of the pin hole 122. As the riveting head 71 continues to apply pressure, the pin 13 smoothly pushes the positioning pin 2141, which has completed its positioning mission, out of the pin hole 122, and then limits and rivets the pin 13.

[0060] This design enables automatic handover and retraction between the tool and the workpiece, eliminating the need for an additional drive mechanism to retrieve the positioning pin 2141, simplifying the structure and avoiding motion interference. Furthermore, the riveting device 700 or the fixture 212 is equipped with a limiting structure (such as a mechanical stop or position control via a servo motor) that restricts the pin 13 from sliding further after it has been pushed out of the pin hole 122 by a set distance, thereby precisely defining the final assembly position of the pin 13 and ensuring product consistency.

The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
