Description
Technical Field
[0001] The present application relates to the technical field of riveting devices, and in particular to a double-sided automatic riveting machine for HDMI terminals. Background Art
[0002] HDMI is a high-definition multimedia interface for fully digital image and audio transmission. It consists of an HDMI cable and an HDMI connector fixedly connected. When connecting the HDMI cable and the HDMI connector, the several transmission wire ends in the HDMI cable are first arranged into two groups according to technical requirements. The two groups of HDMI transmission wire ends are then overlapped with the pins on one side of the connector. However, the overlap is not secure, so the HDMI wire ends are generally soldered to the pins of the connector. However, the soldering process is cumbersome and affects signal transmission efficiency.
[0003] To this end, the relevant technology discloses a terminal riveting machine, which consists of a frame, a transmission device, a sliding assembly, and a fixed assembly. The frame includes an upper crossbeam, left and right columns and a base. The transmission device is installed on the frame. The transmission device includes a transmission shaft. The sliding assembly is mainly composed of a sliding block, an upper die base, and an upper die. The sliding block is arranged at the lower part of the transmission device and is connected to the transmission shaft of the transmission device. The sliding block is connected to the left and right columns in a sliding fit. The upper die base is fixed on the lower end face of the sliding block, and the upper die is arranged on the lower end face of the upper die base. The fixed assembly is mainly composed of a lower die base, a lower die, and a terminal positioning card. The lower die base is fixed on the upper end face of the base of the frame, and the lower die and the terminal positioning card are arranged on the upper end face of the lower die base.
[0004] Although the related technology improves the operating efficiency to a certain extent by placing the overlapped terminals into the terminal positioning card, and then riveting and removing them, the related technology still requires the transmission line heads to be arranged, which will result in redundant operating steps and it is difficult to improve overall work efficiency. Summary of the Invention
[0005] The purpose of the present invention is to provide an automatic double-sided riveting machine for HDMI terminals to solve the technical problem that the existing technology still needs to arrange the transmission line heads when riveting HDMI terminals, resulting in redundant operation steps and difficulty in improving overall work efficiency.
[0006] The present application provides an HDMI terminal double-sided automatic riveting machine comprising:
[0007] A rack, and components fixedly connected to the rack,
[0008] A clamping member, used for clamping and fixing the HDMI connector;
[0009] Support plates, there are two support plates, the two support plates are located between the two groups of thread ends for supporting the two groups of thread ends, and the support plates are provided with avoidance grooves;
[0010] Double-sided riveting assembly, used to rivet the wire ends to the pins of the HDMI connector;
[0011] An automatic alignment assembly is located between the frame and the double-sided riveting assembly, and the automatic alignment assembly can move along the length direction of the support plate;
[0012] In the process of the automatic arrangement and alignment component moving toward the rack, multiple thread ends can be pressed and combed.
[0013] By adopting the above technical solution, the clamping part ensures the stability of the HDMI connector during the riveting process and avoids the movement of the connector. The double support plate supports and separates the two groups of thread ends, effectively preventing the thread ends from interfering with each other during the riveting process, thereby ensuring that the thread ends are neatly arranged and accurately aligned. The double-sided riveting assembly can rivet both sides of the HDMI connector at the same time, eliminating the uneven force problem caused by single-sided riveting and improving the riveting efficiency. At the same time, the automatic arrangement and alignment assembly can automatically press and comb multiple thread ends during movement, realizing the automatic arrangement and alignment of the thread ends, reducing the arrangement operation steps and improving overall work efficiency.
[0014] Preferably, the automatic arrangement alignment component includes:
[0015] a first driving member, one end of which is fixedly connected to the frame;
[0016] a fixed plate, fixedly connected to the other end of the first driving member;
[0017] a first pressing roller, rotatably connected to the fixed plate, the first pressing roller being disposed close to and abutting against the terminal head;
[0018] The combing and aligning member is hinged to the first driving member and is located before the double-sided riveting assembly and the fixing plate. The combing and aligning member is used to comb multiple disordered thread ends and align them to the pins of the HDMI connector that matches them.
[0019] By adopting the above technical solution, the first pressing roller rotatably connected to the fixed plate approaches and abuts the wire ends, and the first pressing roller is driven to rotate by the driving member. The rotation of the first pressing roller can evenly arrange the wire ends, ensuring the smooth arrangement of subsequent wire ends and preventing the riveting quality affected by the uneven arrangement of the wire ends. The combing and alignment member is set between the double-sided riveting assembly and the fixed plate, which can effectively comb through multiple disordered wire ends and accurately align them to the pins of the matching HDMI connector, ensuring the accurate alignment of the wire ends and reducing the misalignment and riveting failure caused by the disorder of the wire ends.
[0020] Preferably, the automatic arrangement alignment component further includes:
[0021] The second pressing roller is located between the first pressing roller and the frame, the second pressing roller is rotatably connected to the fixed plate, and the distance between the second pressing roller and the thread end is greater than the distance between the first pressing roller and the thread end.
[0022] By adopting the above technical solution and adding the design of a second pressing roller, the function of the automatic arrangement and alignment component is further optimized and improved. By pressing and combing the thread ends in sections, the disorder of the thread ends is gradually reduced, and the overall arrangement effect of the thread ends is improved. Specifically, the second pressing roller first performs preliminary pressing and combing on the thread ends, initially sorting out most of the disordered state of the thread ends, forming a relatively neat arrangement. Immediately afterwards, the first pressing roller further finely presses and arranges the already preliminarily sorted thread ends to ensure that the thread ends are completely flat and arranged.
[0023] The dual-pressing and combing process not only effectively reduces the degree of thread disorder during the automatic arrangement and alignment process, ensuring that each thread end is accurately aligned with the pins of the HDMI connector, avoiding riveting failures caused by misalignment, but also, by means of segmented pressing and combing, it reduces the pressure of a single pressing roller on the thread ends, preventing damage from excessive pressure and improving overall durability.
[0024] Preferably, the first driving member includes:
[0025] A hydraulic cylinder having an output shaft, wherein the output shaft is fixedly connected to the frame, and the hydraulic cylinder is fixedly connected to the fixing plate.
[0026] By employing this technical solution, the hydraulic cylinder provides a powerful driving force, stably and precisely moving the fixed plate, thereby driving the first pressing roller and the carding alignment member to arrange and align the thread ends. The high control accuracy and stability of the hydraulic system ensures accurate thread arrangement during the arrangement process, avoiding arrangement errors caused by unstable drive.
[0027] Preferably, the combing alignment member includes:
[0028] A plurality of combing blocks, the combing blocks are arranged in pairs, a combing gap is formed between each pair of the combing blocks, and the combing gap is larger than the diameter of the thread end;
[0029] A clamping member is connected to the plurality of combing blocks, and is used to drive the combing gap between each pair of combing blocks to gradually become smaller or larger, and the smaller combing gap can clamp the thread end.
[0030] By adopting the above technical solution, the design of the combing alignment member makes the arrangement of the thread ends more neat and stable. Multiple combing blocks are arranged in pairs, and a combing gap is formed between each pair of combing blocks. The combing gap is larger than the diameter of the thread ends, thereby allowing the thread ends to pass smoothly during the arrangement process and to be effectively combed. The paired arrangement and clamping function of the combing blocks can ensure the neatness and stability of the arrangement of the thread ends, and improve the accuracy of the alignment. The clamping member can adjust the combing gap between each pair of combing blocks. Specifically, when the combing is completed, the combing gap is reduced so that the combing blocks can clamp the thread ends, preventing the thread ends from being offset and reset under the influence of other forces, thereby facilitating subsequent riveting. The above solution is adopted, through precise combing and clamping, it is ensured that each thread end can be accurately aligned to the pins of the HDMI connector.
[0031] Preferably, each pair of the combing blocks is provided with a threaded hole, and the clamping member comprises:
[0032] Each pair of the combing blocks is provided with a threaded hole, and the clamping member comprises:
[0033] a bracket, the bracket being slidably connected to the carding block;
[0034] A connecting rod, one end of which is fixedly connected to the hydraulic cylinder and the other end of which is hinged to the bracket;
[0035] a clamping rod, the clamping rod being rotatably connected to the bracket, the clamping rod comprising a connecting section and a threaded section, the connecting section and the threaded section being spaced apart, the threaded section of the clamping rod passing through the threaded hole, and adjacent threaded sections having opposite thread directions;
[0036] The first servo motor has a rotation output shaft, the rotation output shaft is fixedly connected to the clamping rod, and the first servo motor is used to drive the clamping rod to rotate.
[0037] By employing this technical solution, the threaded holes and clamping rods work together to precisely adjust the gap between the carding blocks, effectively clamping and releasing the thread ends. The design of the threaded segments, with their opposite orientations, allows the clamping positions of both carding blocks to be adjusted simultaneously when the first servo motor drives the clamping rod. This ensures symmetry and precision in adjustment, preventing thread ends from shifting due to other forces.
[0038] Preferably, the combing block is tapered, and the diameter of the combing block gradually decreases from a direction approaching the clamping rod to a direction away from the clamping rod.
[0039] By adopting this technical solution, the tapered carding block can reduce friction during the arrangement and alignment of the threads. As the diameter of the carding block gradually decreases, the contact area of the threads gradually decreases, reducing friction and allowing the threads to pass through the carding block more smoothly.
[0040] Preferably, the clamping member comprises:
[0041] A mounting rod fixedly connected to the frame;
[0042] A finger cylinder is installed on the mounting rod, and the finger cylinder is fixedly connected to the mounting rod. The finger cylinder has air claws, and the air claws are located on both sides of the HDMI connector. The air claws of the finger cylinder can move close to each other to clamp the HDMI connector or move away from each other to release the HDMI connector.
[0043] By adopting the above technical solution, the finger cylinder provides precise control and strong clamping force, which can firmly clamp the HDMI connector and prevent it from moving or offsetting during the riveting process. The air gripper can accurately adjust the clamping force as needed to ensure sufficient stability under different working conditions. In addition, the air gripper design of the finger cylinder can flexibly adapt to HDMI connectors of different specifications and sizes, and has good versatility. Regardless of the size of the connector, the air gripper can achieve reliable clamping through adjustment, reducing the time for equipment adjustment and replacement, and improving production efficiency. Finally, by moving the air grippers closer and farther away from each other, the HDMI connector can be quickly clamped and released, improving the flexibility and efficiency of the operation. After the riveting is completed, the air gripper can quickly release the connector, facilitating subsequent operation and processing, and reducing manual intervention.
[0044] Preferably, the double-sided riveting assembly includes:
[0045] There are two riveting blocks, which are arranged on both sides of the two groups of pins of the HDMI connector, and each riveting block has a guide through hole;
[0046] A guide rod slides through the guide hole, one end of the guide rod being fixedly connected to the frame;
[0047] The second driving member is fixedly connected to the frame, and is used to drive the riveting blocks to move closer to or away from each other.
[0048] By adopting the above technical solution, two relatively arranged riveting blocks are respectively located on both sides of the two groups of pins of the HDMI connector, so that the riveting blocks can rivet both sides of the HDMI connector at the same time, ensuring the uniform distribution of riveting pressure and avoiding the problem of uneven force caused by one-sided riveting, thereby improving the riveting quality and the firmness of the connection. Secondly, the guide rod slides through the guide through hole of the riveting block, and one end is fixedly connected to the frame, providing a stable guiding effect. The guide rod ensures that the riveting block maintains smooth and straight movement during movement, avoids tilting, and further ensures the accuracy of the riveting process. The second drive member cooperates with the riveting block to apply appropriate riveting pressure to firmly rivet the thread end to the pins of the HDMI connector. After the riveting is completed, the second drive member drives the riveting blocks to separate, making it easy to remove the processed HDMI connector, thereby improving the convenience of operation.
[0049] Preferably, a threaded through hole is provided on the riveting block, and the second driving member includes:
[0050] A screw rod having two sections of threads in opposite directions, the screw rod being arranged parallel to the guide rod, the screw rod passing through the threaded through hole and being threadedly connected to the two riveting blocks;
[0051] The second servo motor is fixedly connected to the screw rod, and the second servo motor is used to drive the screw rod to rotate.
[0052] By adopting this technical solution, threaded holes are provided in the rivet blocks, and precise movement of the rivet blocks is achieved through a screw drive system. The screws have opposite threads and are arranged parallel to the guide rods. A second servo motor drives the screws, and this drive controls the movement of the rivet blocks on both sides, thereby achieving precise riveting of the HDMI connector.
[0053] In summary, this application includes at least one of the following beneficial technical effects:
[0054] 1. By setting up the frame, clamping parts, support plate, double-sided riveting components and automatic arrangement and alignment components, the automatic pressing, combing and alignment of the thread ends are realized, which reduces the arrangement operation steps and improves the overall work efficiency;
[0055] 2. By setting up the first driving member, the fixed plate, the first pressing roller, the combing and aligning member and the second pressing roller, the thread ends are arranged flatly through the secondary pressing, and the combing and aligning member effectively combs out multiple disordered thread ends and accurately aligns them to the pins of the matching HDMI connector, ensuring the accurate alignment of the thread ends and reducing misalignment and riveting failure caused by disordered thread ends;
[0056] 3. By setting two riveting blocks, a guide rod and a second driving member, the riveting blocks can rivet both sides of the HDMI connector at the same time, ensuring uniform distribution of riveting pressure, avoiding the problems of uneven force and low efficiency caused by single-sided riveting, and thus improving the riveting quality and efficiency.

[0063] It should be noted that, in the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0064] The following is combined with Figure 1 -Attached Figure 5 , further details of this application are given.
[0065] Example, see Figure 1A double-sided automatic riveting machine for HDMI terminals includes a frame 1, a clamping member 2, a support plate 3, a double-sided riveting component 4 and an automatic arrangement and alignment component 5.
[0066] Reference Figure 1 Frame 1 serves as the basic support structure of the equipment, firmly connecting other components and ensuring the stability and reliable operation of the entire machine. Frame 1 is installed on the workbench in an L-shape, which can withstand the stress generated during the riveting process and ensure the stability of the equipment.
[0067] Reference Figure 1-Figure 3 The clamping member 2 includes a mounting rod 21 and a finger cylinder 22. The mounting rod 21 is fixedly connected to the frame 1, and the finger cylinder 22 is installed on the mounting rod 21 and fixedly connected thereto. The finger cylinder 22 is used to clamp the HDMI connector. The connector 6 to be riveted has 19 built-in pins. These 19 pins are arranged in parallel on the upper and lower sides of the HDMI connector with 9 pins and 10 pins respectively. The finger cylinder 22 has two air claws, which are arranged opposite to each other and located on both sides of the horizontal plane of the HDMI connector. The air claws are controlled to move closer to each other to clamp the HDMI connector, or to move away from each other to release the HDMI connector. By moving the air claws closer to and further away from each other, the HDMI connector can be quickly clamped and released, thereby improving the flexibility of operation.
[0068] Reference Figure 1 and Figure 3 , the finger cylinder 22 provides precise control and strong clamping force to ensure the stability of the HDMI connector during the riveting process and prevent it from moving or offsetting. The air claw can accurately adjust the clamping force as needed to ensure sufficient stability under different working conditions. In addition, the air claw design of the finger cylinder 22 can also flexibly adapt to HDMI connectors of different specifications and sizes, and has good versatility. Regardless of how the size of the connector changes, the air claw can achieve reliable clamping through adjustment, reducing the time for equipment adjustment and replacement, and improving production efficiency. In addition, after the riveting is completed, the air claw can quickly release the connector to facilitate subsequent operations.
[0069] Reference Figure 1The double-sided riveting assembly 4 includes a riveting block 41, a guide rod 42 and a second driving member 43. The two riveting blocks 41 are relatively arranged on the upper and lower sides of the two groups of pins of the HDMI connector. A plurality of extrusion protrusions (not shown in the figure) are provided on the side of the riveting block 41 close to the connector. By driving the riveting blocks 41 on both sides close to each other, each thread end is squeezed into the corresponding pin using a plurality of extrusion protrusions arranged in sequence. A guide through hole is provided on the riveting block 41. The guide rod 42 slides through the guide through hole. One end of the guide rod 42 is fixedly connected to the frame 1 to provide a stable guiding effect, ensuring that the riveting block 41 moves smoothly and linearly during movement to avoid tilting. The second driving member 43 is fixedly connected to the frame 1, and is used to drive the riveting blocks 41 to move closer or farther away from each other, thereby realizing double-sided synchronous riveting of the HDMI connector. The second driving member 43 cooperates with the riveting block 41 to apply appropriate riveting pressure to firmly rivet the thread end to the pin of the HDMI connector. After the riveting is completed, the second driving member 43 drives the riveting block 41 to separate, making it easier to remove the processed HDMI connector. The double-sided riveting assembly 4 can simultaneously rivet both sides of the HDMI connector, eliminating the uneven force problem caused by single-sided riveting and improving riveting efficiency.
[0070] Reference Figure 1 In this embodiment, a threaded through hole is provided on the riveting block 41, and the second driving member 43 includes a screw rod 431 and a second servo motor 432. The screw rod 431 is provided with two sections of threads with opposite directions. The screw rod 431 is arranged parallel to the guide rod 42. The screw rod 431 passes through the threaded through hole and is threadedly connected to the two riveting blocks 41. The rotating shaft of the second servo motor 432 is fixedly connected to the screw rod 431, and the second servo motor 432 is used to drive the screw rod 431 to rotate. The screw rod 431 is driven to rotate by the second servo motor 432, and the transmission of the screw rod 431 can realize the movement control of the riveting blocks 41 on both sides, so that the riveting blocks 41 on both sides are close to or away from each other, thereby achieving the effect of precise riveting of the HDMI connector. It should be noted that in this embodiment, for the convenience of demonstration, Figure 1 The distance between the upper and lower rows of thread ends is larger than the actual operating distance.
[0071] Reference Figure 1 There are two support plates 3, one located between the two groups of thread ends, used to support and separate the two groups of thread ends. The support plates 3 can provide support during the automatic arrangement and alignment of the thread ends. At the same time, a clearance groove 31 for the riveting block 41 is opened in the middle area of the support plate 3, near the bottom of the riveting block 41, to prevent the thread ends from being disturbed by the support plate 3 during the riveting process.
[0072] Reference Figure 1, the automatic arrangement and alignment component 5 is located between the frame 1 and the double-sided riveting component 4, and the automatic arrangement and alignment component 5 can move along the length direction of the support plate 3. The automatic arrangement and alignment component 5 includes a first driving member 51, a fixed plate 52, a first pressing roller 53, a combing and alignment member 54 and a second pressing roller 55. One end of the first driving member 51 is fixedly connected to the frame 1, and the other end is fixedly connected to the fixed plate 52. The first pressing roller 53 is rotatably connected to the fixed plate 52, close to and abutting against the wire ends, and the first pressing roller 53 is driven to rotate by the first driving member 51 to arrange the wire ends flatly. The combing and alignment member 54 is located between the double-sided riveting component 4 and the fixed plate 52, and is used to comb multiple disordered wire ends and accurately align them to the pins of the HDMI connector.
[0073] Reference Figure 1 In this embodiment, the first drive element 51 is a hydraulic cylinder (illustrated only). The hydraulic cylinder has an output shaft fixedly connected to the frame 1 and is fixedly connected to the fixed plate 52. The hydraulic cylinder provides driving force, stably and accurately driving the fixed plate 52 to move, driving the first pressing roller 53 and the carding and aligning member 54 to arrange and align the thread ends. The hydraulic system has high control precision and stability, ensuring accurate arrangement of the thread ends and avoiding arrangement errors caused by unstable drive.
[0074] Reference Figure 1 and Figure 5 The second pressing roller 55 is located between the first pressing roller 53 and the frame 1 and is rotatably connected to the fixed plate 52. The distance between the second pressing roller 55 and the thread end is greater than the distance between the first pressing roller 53 and the thread end. The design of adding the second pressing roller 55 further optimizes and improves the function of the automatic arrangement and alignment component 5. Specifically, the second pressing roller 55 first performs a preliminary pressing on the thread end, and preliminarily arranges most of the disordered state of the thread end to form a relatively neat arrangement. Immediately thereafter, the first pressing roller 53 further finely presses and arranges the preliminarily arranged thread ends to ensure that the thread ends are completely arranged flatly.
[0075] Reference Figure 1 and Figure 5The combing alignment member 54 is hinged to the first driving member 51 and includes a plurality of combing blocks 541 arranged in pairs. A combing gap is formed between each pair of combing blocks 541. The combing gap is larger than the diameter of the thread end, allowing the thread end to pass smoothly and be effectively combed. The multiple combing blocks 541 are arranged in two rows. The combing blocks 541 are located on the left side of the first pressing roller 53. The combing blocks 541 are used to comb the thread ends after pressing them flat. By pressing and combing the thread ends in sections, the disorder of the thread ends is gradually reduced, and the overall arrangement effect of the thread ends is improved. Double pressing and combing can not only effectively reduce the degree of disorder of the thread ends during the automatic arrangement and alignment process, but also ensure that each thread end can be accurately aligned to the pins of the HDMI connector, thereby avoiding riveting failure caused by inaccurate alignment.
[0076] Reference Figure 1 and Figure 5 The clamping member 542 is used to adjust the size of the combing gap. After combing is completed, the combing gap is reduced to clamp the thread ends and prevent them from deflecting. In this embodiment, the combing block 541 is conical, and its diameter gradually decreases from the direction close to the clamping rod 5423 to the direction away from the clamping rod 5423. The conical design reduces friction during the arrangement and alignment of the thread ends, allowing the thread ends to pass through the combing blocks 541 smoothly and be combed quickly. The combing blocks 541 are arranged in two rows, and a threaded hole is provided on the top of each pair of adjacent combing blocks 541. The clamping member 542 includes a bracket 5421, a connecting rod 5422, a clamping rod 5423 and a first servo motor 5424. The bracket 5421 is provided with a slide groove, and the combing block 541 is slidably connected in the slide groove. The clamping rod 5423 is divided into multiple connecting sections and multiple threaded sections, and the threaded sections and the connecting sections are spaced apart. Mounting holes are provided at both ends of the bracket 5421, and the clamping rod 5423 rotates through the mounting holes. The right end of the connecting rod 5422 is fixedly connected to the hydraulic cylinder, and the right end of the bracket 5421 is hinged to the left end of the connecting rod 5422. A torsion spring is installed at the hinge. When there are too many threads on the left side and they are bunched up and difficult to comb, the combing block 541 drives the bracket 5421 and the torsion spring to rotate, thereby tilting the combing block 541 to avoid interference.
[0077] Furthermore, the clamping rod 5423 passes through the threaded holes of the combing blocks 541, with adjacent thread segments running in opposite directions. The first servo motor 5424 drives the clamping rod 5423 to rotate, driving adjacent combing blocks 541 toward or away from each other, thereby clamping and releasing each thread end. It should be noted that the threads clamped by the combing blocks 541 in the first row and the second row are staggered. This arrangement ensures that all threads in each row are clamped, preventing any threads from being missed.
[0078] Reference Figure 1 and Figure 5, the clamping member 542 can adjust the combing gap between each pair of combing blocks 541. Specifically, after combing is completed, the combing gap is reduced so that the combing blocks 541 can clamp the thread ends, preventing the thread ends from deflecting and resetting under the influence of other forces, thereby facilitating subsequent riveting and preventing the thread ends from deflecting or falling due to gravity. Through the cooperation of the threaded hole and the clamping rod 5423, the gap size between the combing blocks 541 can be accurately adjusted to achieve the clamping and release of the thread ends. The design of the thread segments in opposite directions makes it possible to simultaneously adjust the clamping state of the combing blocks 541 on both sides when the first servo motor 5424 drives the clamping rod 5423 to rotate, thereby ensuring the symmetry and accuracy of the adjustment and preventing the thread ends from deflecting under the influence of other forces.
[0079] The implementation principle of the embodiment of this application:
[0080] First, the HDMI connector is placed in the clamp 2 and held in place by the pneumatic grippers of the finger cylinder 22, ensuring stability during the riveting process. An external clamping device (not shown) is then provided to hold the left-hand thread end. The support plate 3 supports and separates the thread end from its upper and lower sides to prevent interference during the riveting process. The automatic riveting alignment assembly 5 is then activated. A hydraulic cylinder drives the fixed plate 52 along the length of the support plate 3, moving from the left to the right of the thread end. This drives the first pressing roller 53 and the second pressing roller 55 to sequentially press the thread end in sections. Simultaneously, the left-hand combing alignment member 54 combs the disordered thread ends one by one and accurately aligns them to the pins of the HDMI connector, ensuring neat alignment. Next, the double-sided riveting assembly 4 is activated. The second servo motor 432 drives the screw 431 to rotate, driving the two riveting blocks 41 toward each other, firmly riveting the thread ends to the pins of the HDMI connector. The guide rod 42 ensures that the riveting blocks 41 maintain smooth, straight movement during movement, preventing tilt. After riveting is complete, the second drive member 43 drives the riveting block 41 apart, facilitating the removal of the finished HDMI connector. After the finished HDMI connector is removed, the excess thread ends on the right side of the clamping block 541 are trimmed. The double-sided riveting design of the present application eliminates the uneven force problem caused by single-sided riveting, while also avoiding the complex, one-by-one arrangement of thread ends and stitches in traditional methods, thereby improving riveting efficiency.
[0081] It should be noted that the servo motor, finger cylinder 22 and hydraulic cylinder in this embodiment are all equipment purchased on the market, and the models can be selected or customized according to actual needs. In this application, we only use them and do not improve their structure and function. For technical personnel in this field, their setting method, installation method and electrical connection method only need to be debugged according to the requirements of their instruction manual, and will not be described in detail here.
[0082] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
