Abstract
Description
Technical Field
[0001] This invention relates to the field of connector manufacturing equipment, and in particular to a double-sided automatic welding machine for high-speed cable connectors. Background Technology
[0002] High-speed cable connectors are key components for high-speed signal transmission in data centers, communication equipment, and high-performance computing systems. They typically contain precision terminal blocks consisting of active and shielding pins, as well as a metal housing for electromagnetic shielding. As signal transmission rates continue to increase to hundreds of Gbps, the manufacturing precision requirements for connectors are becoming increasingly stringent, especially the soldering quality between the housing and the terminal blocks, which directly affects the integrity of the shielding effect and the stability of signal transmission.
[0003] Currently, the production and processing of high-speed cable connectors, especially the welding of terminal strips with housings, typically employs semi-automatic or manual welding methods. In practice, operators first place the rolled terminal strips on a feeding rack, manually pull the strips through the welding station, then use simple clamps to hold and fix the strips, and finally operate the welding equipment to weld the housings on the terminal blocks sequentially. After welding, manual cutting or the activation of a winding mechanism is required to collect the finished strips, resulting in low efficiency. Therefore, this paper proposes a device for double-sided automatic welding of high-speed cable connectors. Summary of the Invention
[0004] To overcome the shortcomings of the prior art, the present invention provides a double-sided automatic welding machine for high-speed cable connectors.
[0005] The technical solution adopted by this invention to solve its technical problem is: This invention provides a double-sided automatic welding machine for high-speed cable connectors, including a frame, a feeding module and a welding device, and further including a feeding device and a receiving module. The feeding device is used to feed the terminal strip, which is provided with terminal blocks and an outer cover. The feeding module is used to transport the terminal blocks and the outer cover to the welding device for welding. The receiving module is used to rewind the material after welding. The frame is also equipped with a mold changing device, which includes a first pressing mold module for use with the welding device. The first pressing mold module is located between the feeding module and the receiving module. The first pressing mold module includes a first frame on the frame and a first driving member on the first frame. The first frame is also equipped with a bottom mold and a top mold. The bottom mold is fixedly mounted on the first frame, and the top mold is slidably mounted on the bottom mold or the first frame and located at the end of the bottom mold away from the first driving member. There is a clearance space between the bottom mold and the top mold for the terminal strip to flow through. The first driving member is used for the bottom mold and the top mold to move closer to or further away from each other.
[0006] Preferably, the mold changing device further includes a second mold module for use with the first mold module. The first and second mold modules are respectively provided with different bottom molds and top molds for pressing and limiting the front and back sides of the terminal block, and for welding the front and back sides in conjunction with the welding device. By adding a second mold module for use with the first mold module and configuring it with bottom molds and top molds for the different structural characteristics of the front and back sides of the terminal block, the mold changing device can quickly switch the mold state in the same equipment to adapt to the requirements of double-sided welding process. This not only ensures that the terminal strip can be accurately and appropriately pressed and limited during welding on both sides, effectively avoiding positioning deviations caused by strip flipping, but also greatly improves the flexibility of the equipment to handle multi-process processing, providing a reliable hardware foundation for the realization of fully automatic double-sided welding.
[0007] Preferably, the top mold is provided with a relief groove for the welding device to perform welding operations, and the top mold is also provided with a first groove connected to the relief groove. The first groove contains a first plate, which is used to abut against the cover. The first plate is provided with a latching protrusion, and the first plate is disposed on the top mold via the latching protrusion. The first plate is used to abut against the non-welding area of the cover so that it fits tightly against the terminal block. The top mold also features a second groove connected to the first groove. The second groove has a circular cross-section, with a diameter larger than the thickness of the first groove. An obstacle clearance groove and a detachable first plate are integrated into the top mold. The first plate precisely abuts against the non-welding area of the cover, achieving pre-compression of the cover before welding, ensuring a tight fit with the terminal block and guaranteeing precise contact and welding strength. Simultaneously, the obstacle clearance groove provides interference-free space for the welding device, ensuring a smooth welding path. Furthermore, the first plate is detachably mounted within the first groove via a latch, and the larger-diameter circular second groove connected to it simplifies the disassembly and maintenance of the first plate, while also providing space for heat dissipation or cleaning, thus improving the module's maintenance convenience.
[0008] Preferably, a first rod is fixedly provided at the end of the top mold near the first driving member, and a second plate is provided at the end of the first rod that slides through the bottom mold away from the top mold. The first driving member drives the top mold to move closer to or away from the bottom mold via the second plate and the first rod. Using the first rod and the second plate as transmission mediators, the driving force of the first driving member is smoothly and accurately transmitted to the top mold. The setting of the first rod sliding through the bottom mold creates a stable guiding structure, ensuring that the top mold maintains a highly linear motion as it moves closer to or away from the bottom mold, avoiding skewing or jamming. This not only ensures the smoothness of the pressing action, but also further improves the positioning accuracy of the terminal strip during the welding process by precisely controlling the pressing gap.
[0009] Preferably, a fourth groove is provided on the bottom mold, and a first block is slidably accommodated within the fourth groove. A second driving component is also provided on the first frame. The second driving component is used to drive the first block closer to or away from the first plate. A protrusion is provided on the top of the first block, which is used to abut against the external plastic sealant at the bottom of the terminal block. The first plate is located on top of the terminal block, and the protrusion is used to cooperate with the first plate to clamp the front and back sides of the terminal block respectively. By setting a first block independently driven by the second driving component in the fourth groove of the bottom mold, and setting a protrusion on its top, active abutment against the external plastic sealant at the bottom of the terminal block is achieved. This structure, together with the first plate located on top of the terminal block, forms a clamping force that cooperates from top to bottom, thereby firmly clamping the terminal block and the cover. This clamping method acts directly on the solid part of the terminal block, rather than relying solely on the material strip for positioning. It can effectively absorb and resist the thermal and mechanical stress generated during the welding process, prevent the terminal block from warping and deforming, and significantly improve the stability of the welding quality.
[0010] Preferably, the output end of the second drive member is provided with a second rod member, which is slidably disposed with the bottom mold. The end of the second rod member away from the second drive member protrudes into the first block in the fourth groove. The first block is hollow and is provided with a third rod member. A fifth groove for accommodating part of the third rod member is opened on the second rod member. The fifth groove is located at the part where the second rod member and the first block cooperate. The fifth groove is S-shaped. The second drive member is used to drive the second rod member to reciprocate in a straight line. When the second rod member reciprocates in a straight line, it drives the first block to move closer to or away from the first plate member through the fifth groove and the third rod member. This transmission mechanism cleverly transforms the linear reciprocating motion of the second drive member into the smooth sliding of the first block in the fourth groove through the cooperation of the S-shaped fifth groove on the second rod member and the third rod member on the first block. The S-shaped groove design serves as a buffer and guide, smoothly decomposing the linear driving force into a longitudinal component that drives the first block closer to or away from the first plate. This not only enables the conversion of the movement direction within a limited space but also absorbs minor impacts during the movement, making the movement of the first block smoother and more precise, and avoiding damage to the terminal block caused by rigid impacts.
[0011] Preferably, the feeding device includes a first feeding module and a second feeding module. The first feeding module is used to provide terminal strips, and the second feeding module is used to provide shielding strips. The terminal block is formed by stamping and molding, and the shielding strip is provided with a cover formed by stamping. The frame is also provided with a conveying module, which is used to transfer the cover in the second feeding module to a predetermined welding area on the terminal block. The welding device is used to weld the cover to the terminal block. Several second feeding modules are provided, each supplying a cover with a different structure. The design, combining the first feeding module with multiple second feeding modules for independent material supply, enables the independent transport and supply of terminal strips and shielding cover strips with different structures. A handling module precisely picks up and transfers the appropriate cover to the designated welding area of the terminal block, achieving automatic material assembly and positioning. The configuration of multiple second feeding modules allows the equipment to flexibly utilize different models or specifications of covers without changing the entire roll of strip, greatly enhancing the equipment's compatibility with diverse products, reducing changeover time, and improving production flexibility and overall efficiency.
[0012] Preferably, the first plate has a protrusion at one end near the terminal block. This protrusion abuts against the cover, allowing the cover to contact the terminal block. A sixth groove is formed on the first plate, extending through the protrusion and the first plate along its protruding direction. A dedicated protrusion at the end of the first plate concentrates the holding force on a specific area of the cover, ensuring effective contact between the cover and the terminal block and avoiding poor contact or pressure dispersion that might occur with large-area pressing. Simultaneously, the sixth groove extending along the protrusion cleverly forms a welding channel or observation window, allowing the welding head or laser of the welding device to directly act on the pressed welding area through the groove. This "pressing as positioning, groove as channel" design allows the pressing and welding actions to be completed simultaneously at the same workstation height, ensuring welding accuracy while simplifying the equipment structure.
[0013] Preferably, the terminal block includes a working pin and a shielding pin, with a working pin provided between two adjacent shielding pins. The housing includes a top portion of the housing and a welding portion provided corresponding to the working pin and the shielding pin. The housing is made of a conductive material, and the welding portion is used to stop the shielding pin, thereby realizing an electrical connection between the housing and the shielding pin. A connecting part is provided between the top of the shell and the welded part. The top of the shell, the welded part and the connecting part are an integral structure. The top of the shell and the welded part are arranged parallel to each other. The connecting part is arranged at an angle relative to the top of the shell and the welded part. The width of the top of the shell is smaller than the distance between two adjacent welded parts. The protrusions fit snugly along the width of the housing, while the sixth groove is located at the welded section of the housing. Through meticulous design of the housing structure (top, welded section, and inclined connecting section), it precisely aligns with the functional pins and shielding pins on the terminal block. In particular, the welded section abuts against the shielding pin to achieve electrical connection, ensuring reliable shielding performance. The integrated structure guarantees the housing's mechanical strength and conductivity. The design of the top width being smaller than the distance between adjacent welded sections facilitates avoiding interference during assembly. In conjunction with this, the protrusions fit snugly along the width of the housing, and the sixth groove precisely corresponds to the welded section. This ensures that during clamping, pressure is applied precisely near the welding area, while the welding channel is aligned perfectly with the welded section, achieving a high degree of uniformity between clamping and welding space, significantly improving the accuracy and efficiency of welding operations.
[0014] Preferably, the feeding module further includes a bracket and a positioning component and a driving component disposed on the bracket. The positioning component is used to limit the terminal strip, and the driving component is used to drive the terminal strip to move along a preset direction. The positioning component includes a support platform and a fifth driving component mounted on the support platform. A second block is located at the end of the support platform away from the fifth driving component, and a fourth plate slides on the second block. An array of third positioning pins is located at the end of the fourth plate near the terminal strip. The fifth driving component drives the third positioning pins to move closer to or away from the terminal strip. The end of the terminal strip in the width direction has a pin groove for accommodating the positioning pins, and the third positioning pins abut against the pin groove arm. This feeding module, through the independent positioning component and the driving component working together, achieves high-precision intermittent feeding of the terminal strip. Specifically, the fifth driving component of the positioning component drives the fourth plate to slide, causing the array of third positioning pins to accurately insert into the pin groove at the end of the terminal strip and abut against the groove arm, achieving a "active insertion + groove arm abutment" positioning method. Compared to traditional friction or edge limiting, this fundamentally eliminates accumulated feeding errors, ensuring that the terminal strip at each station is accurately locked in the preset welding position. This high-precision positioning capability is key to ensuring consistent welding quality and effectively prevents welding misalignment or failure due to feeding deviations.
[0015] The beneficial effects of this invention are: Terminal strips are continuously supplied by the feeding device and precisely conveyed to the welding device by the feeding module. Stable welding is carried out with the cooperation of the first pressing module in the mold changing device. Finally, the take-up module automatically completes the winding. The mold changing device drives the top mold to move relative to the fixed bottom mold through the first drive component on the first frame, thereby precisely controlling the increase and decrease of the clearance space between the bottom mold and the top mold. This enables rapid positioning and pressing of the terminal strips and covers that pass through. This not only ensures the positional accuracy of the terminal strips during the welding process and improves the yield and consistency of double-sided welding, but also greatly reduces manual intervention through the automated feeding, feeding, pressing, and take-up process, significantly improving overall production efficiency and reducing the labor intensity of operators.

[0027] Reference Figures 1 to 18 A double-sided automatic welding machine for high-speed cable connectors includes a frame 1, a feeding module 2, and a welding device 3. It also includes a feeding device 6 and a receiving module 5. The feeding device 6 is used to unwind terminal strip 610, which is provided with terminal blocks 611 and an outer cover 621. The feeding module 2 is used to transport the terminal blocks 611 and the outer cover 621 to the welding device 3 for welding. The receiving module 5 is used to rewind the material after welding. The frame 1 is also provided with a mold changing device 7. The mold changing device 7 includes a first pressing mold module 71 for use with the welding device 3. The first pressing mold module 71 is located between the feeding module 2 and the receiving module 5. The first pressing mold module 71 is used in conjunction with the welding device 3. The first pressing mold module 71 includes a first frame 711 on the frame 1 and a first driving member 712 on the first frame 711. The first frame 711 is also provided with a bottom mold 713 and a top mold 714. The bottom mold 713 is fixedly installed on the first frame 711. The top mold 714 is slidably installed on the bottom mold 713 or the first frame 711 and is located at the end of the bottom mold 713 away from the first driving member 712. There is a clearance space between the bottom mold 713 and the top mold 714 for the terminal strip 610 to flow through. The first driving member 712 is used to drive the bottom mold 713 and the top mold 714 to move closer or further away from each other.
[0028] With the above-described structure, during use, the terminal strip 610 is continuously supplied via the feeding device 6 and precisely conveyed to the welding device 3 by the feeding module 2. Stable welding is performed with the cooperation of the first pressing module 71 in the mold changing device 7. Finally, the take-up module 5 automatically completes the winding. The mold changing device 7 drives the top mold 714 to move relative to the fixed bottom mold 713 via the first driving component 712 on the first frame 711. This precisely controls the increase and decrease of the clearance space between the bottom mold 713 and the top mold 714, realizing the rapid positioning and pressing of the terminal strip 610 and the cover 621. This not only ensures the positional accuracy of the terminal strip 610 during the welding process and improves the yield and consistency of double-sided welding, but also significantly reduces manual intervention and improves the overall production efficiency and reduces the labor intensity of operators through the automated feeding, feeding, pressing, and take-up process.
[0029] The feeding module, the handling module 4, and the welding module 3 can be completed using existing conventional technologies.
[0030] The top mold 714 is provided with a first positioning pin 7145, which is used to position or cancel the positioning of the terminal strip 610.
[0031] In this embodiment, the welding device 3 is preferably selected as a laser welding device.
[0032] The frame 1 is equipped with a central control device, and the frame 1 is equipped with a cooling fan for dissipating heat from the internal central control device. The first feeding module 61, the second feeding module 62 and the receiving module 5 are all equipped with control cabinets, and the control cabinets are communicatively connected to the central control device inside the frame 1.
[0033] The first feeding module 61, the second feeding module 62, and the receiving module 5 are all set on the external base surface. The frame 1 is equipped with a protective cabinet. The first feeding module 61, the second feeding module 62, and the receiving module 5 are used in conjunction with the various device modules on the frame 1 through the protective cabinet. In other embodiments, the first feeding module 61, the second feeding module 62, and the receiving module 5 can also be set on the frame 1.
[0034] Specifically, the mold changing device 7 also includes a second mold module 72 used in conjunction with the first mold module 71. The first mold module 71 and the second mold module 72 are respectively provided with different bottom molds 713 and top molds 714 for pressing and limiting the front and back sides of the terminal block 611, and for welding the front and back sides in conjunction with the welding device 3. By adding a second mold module 72 that works with the first mold module 71, and configuring it with bottom molds 713 and top molds 714 for the different structural characteristics of the front and back sides of the terminal block 611, the mold changing device 7 can quickly switch the mold state in the same equipment to adapt to the double-sided welding process requirements. This not only ensures that the terminal strip 610 can be accurately and appropriately pressed and limited during the welding of the front and back sides, effectively avoiding the positioning deviation caused by the strip flipping, but also greatly improves the flexibility of the equipment to cope with multi-process processing, providing a reliable hardware foundation for the realization of fully automatic double-sided welding.
[0035] Except for the bottom mold 713 and the top mold 714, the first molding module 71 and the second molding module 72 have the same technical features and basic principles, and can be understood accordingly. The reason for the difference in the top mold 714 of the first molding module 71 and the second molding module 72 is that the structure and position of the cover 621 on the front and back sides of the terminal block 611 are different. The bottom mold 713 has a cavity for accommodating the plastic sealant 63, which is intended to prevent the terminals on the terminal block 611 from being squeezed and deformed.
[0036] Preferably, the first molding module 71 and the second molding module 72 share the same reference positioning component. The reference positioning component includes a reference guide block and a reference positioning pin disposed on the frame 1. The first molding module 71 and the second molding module 72 are respectively provided with positioning holes that cooperate with the reference positioning pin. When switching molding modules, the two molding modules are guided by the reference guide block and inserted into the positioning hole by the positioning pin to achieve rapid locking and positioning of the two molding modules under the same spatial reference.
[0037] Preferably, the support plate 11 is provided with an origin sensor for detecting the position of the pressing mold module. The origin sensor is connected to the central control equipment for position calibration after the pressing mold module is switched, so as to ensure that the terminal block 611 uses the same welding reference when welding on both sides.
[0038] The above structural design avoids reference offset issues caused by mold switching, ensuring coaxiality and weld point consistency in double-sided welding.
[0039] A support plate 11 is slidably mounted on the frame 1. The frame 1 is also equipped with a limiting component for positioning and locking the support plate 11. The first pressing module 71 is mounted on the support plate 11. The displacement and locking of the first pressing module 71 can be achieved by an external drive motor or telescopic rod in conjunction with the limiting component. For example, the second pressing module 72 can be fixed relative to the first pressing module 71 to achieve the conversion of the pressing module by an external drive motor or telescopic rod. Of course, a disassembly and assembly method can also be adopted, and the first pressing module 71 or the second pressing module 72 can be mounted on the support plate 11 as required.
[0040] Specifically, the top mold 714 is provided with a relief groove 7140 for welding operation by the welding device 3. The top mold 714 is also provided with a first groove 7141 that communicates with the relief groove 7140. The first groove 7141 contains a first plate 7142. The first plate 7142 is used to abut against the cover 621. The first plate 7142 is provided with a latching protrusion. The first plate 7142 is provided on the top mold 714 via the latching protrusion. The first plate 7142 is used to abut against the non-welding area of the cover 621 so that it fits tightly against the terminal block 611. The top mold 714 is also provided with a second groove 71410 that communicates with the first groove 7141. The second groove 71410 has a circular cross-section, and its diameter is larger than the thickness of the first groove 7141. The top mold 714 integrates a clearance groove 7140 and a detachable first plate 7142. The first plate 7142 precisely abuts against the non-welding area of the cover 621, achieving pre-compression of the cover 621 before welding, making it tightly fit with the terminal block 611, thereby ensuring precise contact and welding strength at the welding point. At the same time, the clearance groove 7140 provides interference-free space for the operation of the welding device 3, ensuring unobstructed welding path. In addition, the first plate 7142 is detachably installed in the first groove 7141 by means of a snap-fit, and is connected to the second circular groove 71410 with a larger diameter. This not only simplifies the disassembly and maintenance process of the first plate 7142, but also reserves space for heat dissipation or cleaning needs, thus improving the maintenance convenience of the module.
[0041] A plurality of first grooves 7141 are provided, and similarly, second grooves 71410 are provided corresponding to the first grooves 7141. Each first groove 7141 corresponds to two second grooves 71410. The two second grooves 71410 are located at both ends of the length opening direction of the first groove 7141. The plurality of second grooves 71410 at the same end of the plurality of first grooves 7141 are not collinear.
[0042] The first plate 7142 of the second molding module 72 is provided with a chamfer or groove. The chamfer or groove is located at one end of the first plate 7142 near the terminal block 611. The chamfer or groove is used to prevent deformation of the cover 621 and the terminal block 611 while they are in contact, so as not to affect the welding effect.
[0043] The first plate 7142 is also equipped with reinforcing ribs to improve structural strength.
[0044] Specifically, a first rod 7143 is fixedly provided at one end of the top mold 714 near the first driving member 712, and a second plate 7144 is provided at the other end of the first rod 7143 away from the top mold 714, which slides through the bottom mold 713. The first driving member 712 drives the top mold 714 to move closer to or away from the bottom mold 713 via the second plate 7144 and the first rod 7143. The first rod 7143 and the second plate 7144 serve as transmission media to smoothly and accurately transmit the driving force of the first driving member 712 to the top mold 714. The sliding penetration of the first rod 7143 through the bottom mold 713 creates a stable guiding structure, ensuring that the top mold 714 maintains a highly linear motion as it moves closer to or away from the bottom mold 713, avoiding skewing or jamming. This not only ensures the smoothness of the pressing action but also further improves the positioning accuracy of the terminal strip 610 during the welding process by precisely controlling the pressing gap.
[0045] Specifically, a fourth groove 7132 is provided on the bottom mold 713, and a first block 717 is slidably accommodated in the fourth groove 7132. A second driving member 715 is also provided on the first frame 711. The second driving member 715 is used to drive the first block 717 to move closer to or away from the first plate 7142. A protrusion is provided on the top of the first block 717. The protrusion is used to stop the external plastic sealant 63 at the bottom of the terminal block 611. The first plate 7142 is located on the top of the terminal block 611. The protrusion is used to cooperate with the first plate 7142 to clamp the front and back sides of the terminal block 611 respectively. By setting a first block 717 independently driven by the second driving member 715 in the fourth groove 7132 of the bottom mold 713 and setting a protrusion on its top, active stopping of the external plastic sealant 63 at the bottom of the terminal block 611 is achieved. This structure, together with the first plate 7142 located on top of the terminal block 611, forms a clamping force that engages with the terminal block 611, thereby firmly clamping the terminal block 611 and the cover 621. This clamping method acts directly on the solid part of the terminal block 611, rather than relying solely on the strip for positioning. It can effectively absorb and resist the thermal and mechanical stresses generated during the welding process, prevent the terminal block 611 from warping and deforming, and significantly improve the stability of the welding quality.
[0046] The protrusion is mainly used to stop the injection-molded plastic seal 63 on the terminal block 611, while the first plate 7142 is mainly used to stop the cover 621 on the terminal block 611 that has been initially placed and limited.
[0047] Specifically, the output end of the second driving member 715 is provided with a second rod member 716, which is slidably disposed with the bottom mold 713. The end of the second rod member 716 away from the second driving member 715 protrudes into the first block 717 in the fourth groove 7132. The first block 717 is hollow and is provided with a third rod member 7171. The second rod member 716 is provided with a fifth groove 7161 for accommodating part of the third rod member 7171. The fifth groove 7161 is located at the part where the second rod member 716 mates with the first block 717. The body 7161 is S-shaped. The second driving member 715 drives the second rod member 716 to reciprocate in a straight line. When the second rod member 716 reciprocates in a straight line, it drives the first block 717 to move closer to or away from the first plate member 7142 via the fifth groove 7161 and the third rod member 7171. This transmission mechanism cleverly transforms the linear reciprocating motion of the second driving member 715 into a smooth sliding motion of the first block 717 within the fourth groove 7132 through the cooperation of the S-shaped fifth groove 7161 on the second rod member 716 and the third rod member 7171 on the first block 717. The design of the S-shaped groove plays a role in buffering and guiding, and can smoothly decompose the linear driving force into a longitudinal component that drives the first block 717 to move closer to or away from the first plate member 7142. This not only realizes the conversion of the motion direction within a limited space, but also absorbs the small impacts during the motion process, making the movement of the first block 717 more gentle and precise, and avoiding damage to the terminal block 611 caused by rigid impacts.
[0048] Preferably, the outer periphery of the third rod 7171 is provided with a wear-resistant kit, which slides in contact with the groove wall of the fifth groove 7161 to reduce sliding friction resistance.
[0049] In a further preferred embodiment, the second rod 716 and the third rod 7171 are made of heat-treated high-hardness alloy steel, and the surface of the fifth groove 7161 is provided with a wear-resistant coating.
[0050] Preferably, the bottom of the fifth groove 7161 is provided with a lubricating oil groove or a solid lubricating insert to reduce wear during long-term reciprocating motion.
[0051] The above structural design can significantly improve the service life of the S-type transmission mechanism and avoid clamping stroke errors or jamming caused by wear.
[0052] In other embodiments, a third groove 7131 may also be provided on the bottom mold 713. The third groove 7131 is strip-shaped and its length direction is parallel to the movement direction of the first block 717 and the third rod 7171.
[0053] Specifically, the feeding device 6 includes a first feeding module 61 and a second feeding module 62. The first feeding module 61 is used to provide terminal strip 610, and the second feeding module 62 is used to provide shielding strip 620. The terminal block 611 is formed by stamping and molding, and the shielding strip 620 is provided with a cover 621 formed by stamping. The frame 1 is also provided with a conveying module 4, which is used to transfer the cover 621 in the second feeding module 62 to a predetermined welding area on the terminal block 611. The welding device 3 is used to weld the cover 621 to the terminal block 611. Several second feeding modules 62 are provided, each supplying a housing 621 with a different structure. This separate feeding design of the first feeding module 61 and multiple second feeding modules 62 enables independent conveying and supply of terminal strips 610 and shielding cover strips 620 with different structures. The handling module 4 is responsible for precisely gripping and transferring the appropriate housing 621 to the predetermined welding area of the terminal block 611, achieving automatic assembly and positioning of materials. The configuration of multiple second feeding modules 62 allows the equipment to flexibly utilize different models or specifications of housings 621 without changing the entire roll of strip, greatly enhancing the equipment's compatibility with diverse products, reducing changeover time, and improving production flexibility and overall efficiency.
[0054] The second feeding module 62 is also equipped with a cutting mold, which is used to cut and separate the cover 621 from the shielding cover strip 620, and then transport it through the transport module.
[0055] It is worth noting that the terminal strip 610 is provided with a terminal block 611 and an outer cover 621 located on the terminal block 611. The outer cover 621 is transported and cut by the second feeding module 62 and then transported to the terminal block 611 and then fed by the feeding module 2.
[0056] The feeding module 2 includes a bracket 20, on which an opening and closing assembly 25 is provided. The opening and closing assembly 25 includes a cover 251 and a sixth driving member 252 for driving the cover 251 to move. The sixth driving member 252 is used to drive the cover 251 to move when the transport module transports the cover 621 to the terminal block 611, so as to form a space for opening and closing the working path of the transport module. At the same time, the bracket 20 is also provided with a support assembly 26, which is used to abut the bottom of the terminal block 611 in conjunction with the transport module to ensure that the cover 621 is installed firmly.
[0057] The support assembly 26 includes a support member 261 and a fourth drive member 263 disposed on the bracket 20. The fourth drive member 263 is used to drive the support member 261 to move closer to or away from the terminal block 611.
[0058] The support member 261 is also provided with a second positioning pin 262. The end of the second positioning pin 262 protrudes out of the free end of the support member 261. The second positioning pin 262 is engaged with the support member 261. There are at least two second positioning pins 262.
[0059] The feeding module 2 includes a first plate 201 disposed on the bracket 20 and a second plate 202 disposed on the first plate 201. There is a gap between the first plate 201 and the second plate 202 for accommodating the edge of the terminal strip 610. The edge of the terminal strip 610 is provided with an array of holes. Similarly, the first plate 201 and the second plate 202 are provided with corresponding arrays of holes for the insertion of positioning pins.
[0060] A third plate 203 is also provided on the first plate 201 or the second plate 202. The first plate 201 and the second plate 202 are each provided with two sets of matching plates. The two sets of first plates 201 and second plates 202 are respectively provided at both ends in the width direction of the terminal strip 610. The third plate 203 is located between the two sets of first plates 201 and second plates 202 and above the terminal strip 610 to limit the cover 621 placed on the terminal block 611.
[0061] The bottom of the third plate 203 is provided with a protruding strip. A beveled groove is provided on the side of the protruding strip for the terminal material strip 610 to flow in. The cutting direction of the beveled groove is inclined in the longitudinal direction and also in the horizontal direction, for extruding the guide cover 621. There are multiple third plates 203, and different third plates 203 are set with different covers 621. For example, the bottom protruding strip of the first third plate 203 is provided with a beveled groove for guiding the first cover 621. The bottom of the second third plate 203 is provided with at least two protruding strips. One of the protruding strips is provided with a beveled groove for guiding the second cover 621, and the other protruding strip does not need to be provided with a beveled groove.
[0062] Specifically, the first plate 7142 has a protrusion 71421 at one end near the terminal block 611. The protrusion 71421 is used to abut against the cover 621, so that the cover 621 contacts the terminal block 611. A sixth groove 71422 is formed on the first plate 7142. The sixth groove 71422 penetrates the protrusion 71421 and the first plate 7142 along the protruding direction of the protrusion 71421. The dedicated protrusion 71421 at the end of the first plate 7142 concentrates the holding force in a specific area of the cover 621, ensuring effective contact between the cover 621 and the terminal block 611 and avoiding poor contact or pressure dispersion that may be caused by large-area pressing. At the same time, the sixth groove 71422, which penetrates along the protrusion direction, cleverly forms a welding channel or observation window, allowing the welding head or laser of the welding device 3 to pass through the groove and directly act on the pressed welding part. This "pressing and positioning, tank as channel" design allows the pressing and welding actions to be completed simultaneously at the same workstation height, ensuring welding accuracy while simplifying the equipment structure.
[0063] The sixth groove 71422 is square in shape, and the diameter of the sixth groove 71422 is equal to the width of the shielding pin 613. Of course, the diameter of the sixth groove 71422 can also be appropriately larger or smaller than the width of the shielding pin 613, but it should not affect the working pin 612 during welding.
[0064] Specifically, the terminal block 611 includes a function pin 612 and a shielding pin 613. A function pin 612 is provided between two adjacent shielding pins 613. The cover 621 includes a top 622 and a welding part 623 corresponding to the function pin 612 and the shielding pin 613. The cover 621 is made of conductive material. The welding part 623 is used to stop the shielding pin 613, so as to realize the electrical connection between the cover 621 and the shielding pin 613. A connecting part 624 is provided between the top of the shell 622 and the welding part 623. The top of the shell 622, the welding part 623 and the connecting part 624 are an integral structure. The top of the shell 622 and the welding part 623 are arranged in parallel. The connecting part 624 is inclined relative to the top of the shell 622 and the welding part 623. The width of the top of the shell 622 is smaller than the distance between two adjacent welding parts 623. The protrusion 71421 is adapted to fit the housing 621 along its width direction. The sixth groove 71422 is located at the welded portion 623 of the housing 621. Through refined design of the structure of the housing 621 (top 622, welded portion 623, inclined connecting portion 624), it precisely corresponds to the functional pins 612 and shielding pins 613 on the terminal block 611. In particular, the welded portion 623 abuts against the shielding pin 613 to achieve electrical connection, ensuring the reliability of the shielding effect. The integrated structure ensures the mechanical strength and conductivity of the housing 621. The design of the width of the top 622 being smaller than the spacing between adjacent welded portions 623 facilitates avoiding interference during assembly. In conjunction with this, the protrusion 71421 is adapted to press along the width of the cover, and the sixth groove 71422 is precisely opened to correspond to the welding part 623. This ensures that during the pressing process, the pressure is applied precisely to the vicinity of the welding area, and the welding channel is precisely aligned with the welding part 623 that needs to be welded. This achieves a high degree of uniformity between the pressing and welding space, greatly improving the accuracy and efficiency of the welding operation.
[0065] Terminal block 611 is provided with molding compound 63, molding compound 63 is provided with positioning protrusion 631 for positioning guide cover 621, positioning protrusion 631 is trapezoidal, cover 621 is provided with groove 625, groove 625 is provided between welding part 623 and connecting part 624, and extends to top of cover 622, groove 625 is used to accommodate positioning protrusion 631, the width of the area of molding compound 63 on the actuating pin 612 is smaller than the width of the area of molding compound 63 not used for molding compound 63.
[0066] Specifically, the feeding module 2 also includes a bracket 20 and a positioning component 22 and a driving component 23 disposed on the bracket 20. The positioning component 22 is used to limit the terminal strip 610, and the driving component 23 is used to drive the terminal strip 610 to move along a preset direction. The positioning component 22 includes a support platform 221 and a fifth driving member 229 disposed on the support platform 221. A second block 222 is disposed at one end of the support platform 221 away from the fifth driving member 229. A fourth plate 223 is slidably disposed on the second block 222. An array of third positioning pins 224 is disposed at one end of the fourth plate 223 near the terminal strip 610. The fifth driving member 229 is used to drive the third positioning pins 224 to approach or move away from the terminal strip 610. The end of the terminal strip 610 in the width direction is provided with a pin groove for accommodating the positioning pins. The third positioning pins 224 are used to abut against the pin groove arm. The feeding module 2 works in cooperation with the driving component 23 through the independent positioning component 22 to achieve high-precision intermittent feeding of the terminal strip 610. In this process, the fifth driving component 229 of the positioning component 22 drives the fourth plate 223 to slide, so that the third positioning pin 224 set in the array is precisely inserted into the pin groove at the end of the terminal strip 610 and abuts against the groove arm, realizing the positioning method of "active insertion + groove arm abutment". Compared with the traditional friction or edge limit, it can fundamentally eliminate the cumulative feeding error and ensure that the terminal strip 610 at each station can be accurately locked in the preset welding position. This high-precision positioning capability is the key to ensuring the consistency of subsequent welding quality and effectively prevents welding misalignment or failure caused by feeding deviation.
[0067] Preferably, the output end of the drive component 23 is provided with a positioning component 22, and the drive component 23 moves back and forth along the moving direction of the terminal strip 610 via the drive positioning component 22, so as to realize the rhythmic movement of the terminal strip 610.
[0068] The output end of the fifth driving member 229 is provided with a fifth plate 226, which slides through the second block 222. The fifth plate 226 is provided with an S-shaped groove 227. The fourth plate 223 is provided with a fourth rod 225 for partially accommodating in the groove 227. The fifth driving member 229 drives the fifth plate 226 to move linearly, thereby causing the fourth rod 225 to slide in the groove 227. This allows the fourth plate 223 and the third positioning pin 224 provided on the fourth plate 223 to move closer to or further away from the terminal strip 610. The third positioning pin 224 then controls whether the terminal strip 610 is positioned.
[0069] The second block 222 is also provided with a cover plate 228, which is used to facilitate the disassembly and maintenance of the fifth block 226 or other components.
[0070] The second plate 202 has a clearance groove 2021 for the third positioning pin 224 of the positioning component 22 to pass through, so as to limit or cancel the limit of the terminal strip 610. The third positioning pin 224 includes a first pin part and a second pin part. The second pin part is used for the initial insertion into the positioning hole opened on the terminal strip 610, and the first pin part is used for the secondary insertion into the positioning hole opened on the terminal strip 610. Both the first pin part and the second pin part are columnar. The free end of the second pin part is tapered. The diameter of the first pin part is larger than the diameter of the second pin part. An arc-shaped transition part is provided between the first pin part and the second pin part for the transition when inserting the terminal strip 610. The length of the second pin part is between one-quarter and one-half of the length of the first pin part. Of course, the other positioning pins are constructed in the same way as the third positioning pin 224.
[0071] The support 20 has a tornado assembly 21 at each end along its length. The tornado assembly 21 includes a tornado gun head and an external drive rod for driving the tornado gun head to approach or move away from the terminal strip 610. The support 20 also has a material collection hopper at its bottom.
[0072] The bottom of the bracket 20 is also provided with a third driving component 24, which is used to drive the two sets of first plates 201 to move closer or further apart, thereby driving the two sets of second plates 202 to move closer or further apart.
[0073] In actual use, only one set of first plates 201 is slidably set relative to the frame 1, which can be driven by the third drive component 24. The drive component 23 and its positioning component 22 are both set corresponding to the first plates 201 fixed relative to the frame 1. Correspondingly, only the second plates 202 fixed relative to the frame 1 have clearance grooves 2021.
[0074] Preferably, the bottom mold 713 and the top mold 714 are provided with cooling channels, which are connected to an external circulating cooling system for temperature control of the mold during the welding process.
[0075] Preferably, the frame 1, the feeding module 2 and the mold changing device 7 are all equipped with a grounding structure, and the grounding structure is connected to the factory grounding system.
[0076] More preferably, the contact parts between the feeding module 2 and the mold changing device 7 are provided with an antistatic coating or are made of antistatic material.
[0077] The above structural design prevents static electricity buildup from damaging the internal terminals of high-speed cable connectors, thus improving product reliability.
