Description

Technical Field

[0001] This invention relates to the field of connector manufacturing technology, and in particular to an automatic assembly machine for SMB connectors. Background Technology

[0002] The SMB (Sub-Miniature Version B) connector is a miniature push-lock interface widely used in RF design. It is favored for its compact and fast characteristics and is very suitable for applications that require high installation density and efficient insertion / removal, and operate in relatively stable environments.

[0003] In existing technologies, SMB connectors are mainly composed of components such as outer conductors, insulators, and center pins. However, due to the miniaturization of SMB connectors, the current assembly process is mostly done manually in semi-manual or semi-automatic assembly lines. Manually controlling product consistency relies heavily on worker skill and subjective judgment, which can easily cause visual fatigue and damage workers' eyesight. This makes it unsuitable for large-scale production. Furthermore, manual or semi-automatic assembly lines generally involve multiple handovers and shipments between processes, resulting in cumbersome product turnover and large fluctuations in yield. At the same time, there is a lack of intelligent monitoring and data traceability capabilities, making it impossible to collect parameters of each process in real time and provide feedback for optimization.

[0023] like Figures 1 to 12 As shown, an automatic assembly machine for SMB connectors includes: a four-station turntable mechanism 1, comprising a first turntable assembly 11 and a first feeding assembly 12 for feeding the outer conductor, a second feeding assembly 13 for feeding the insulator, and a first riveting assembly 14 for pressing the outer conductor and the insulator together; a two-station crimping mechanism 2, comprising a crimping assembly 21 for creating riveting points on the outside of the outer conductor, causing the inner wall of the outer conductor to be recessed inward to fix the insulator, and a pressing assembly 22 that cooperates with the crimping assembly 21; and an eight-station turntable mechanism 3, comprising a second turntable assembly 31 and a first feeding assembly 12 surrounding the second turntable. The turntable assembly 31 includes a first rejection assembly 32 for insulator detection and removal, a third feeding assembly 33 for feeding the center pin, a second riveting assembly 34 for pressing the center pin, a second rejection assembly 35 for detecting and removing the center pin, and a feeding assembly 36 for removing qualified finished products. The transfer mechanism 4 is located on one side of the dual-station crimping mechanism 2. The transfer mechanism 4 is equipped with a first gripping assembly 41 for transferring the assembled outer conductor and insulator to the dual-station crimping mechanism 2 for fixing, and a second gripping assembly 42 for transferring to the eight-station turntable mechanism 3 and linked with the first gripping assembly 41.

[0024] The above solution employs a dual-rotor continuous automated assembly architecture, integrating feeding, pressing, riveting, inspection, and unloading into a single machine. This enables automated assembly of outer conductors, insulators, and center pins, saving labor, reducing production costs, and significantly improving assembly efficiency and accuracy. It also supports real-time detection and removal of defective products, and optimizes the data through cloud storage and effective analysis, achieving intelligent monitoring and traceability management of product quality issues.

[0025] The automatic assembly machine of this embodiment is applicable to SMB elbow two-hole diamond-shaped socket RF connectors, specifically used in high-reliability wire harness manufacturing scenarios such as vehicle-mounted millimeter-wave radar wire harnesses for new energy vehicles, 5G base station RF module wire harnesses, optical camera module wire harnesses, high-flexibility wire harnesses for industrial robots, and aerospace microwave component wire harnesses. This SMB connector adopts a crimping structure and quick-lock docking design, mainly composed of outer conductors, insulators, and center pins, enabling automated and efficient assembly of individual components. The automatic assembly machine is equipped with a frame and a platform placed above the frame. The four-station turntable mechanism 1, the two-station crimping mechanism 2, and the eight-station turntable mechanism 3 are arranged horizontally above the platform, with the transfer mechanism 4 positioned between the four-station turntable mechanism 1 and the eight-station turntable mechanism 3. The first feeding component 12 and the second feeding component 13 sequentially feed the outer conductor... The conductor and insulator are transported to the first turntable assembly 11 for assembly, and then pressed into place by the first riveting assembly 14. Next, the first gripping assembly 41 transports the pressed outer conductor and insulating sleeve to the dual-station crimping mechanism 2, and through the cooperation of the crimping assembly 21 and the pressing assembly 22, riveting points are made on the outside of the outer conductor, so that the inner wall of the outer conductor is recessed inward to fix the insulator. Then, the second gripping assembly transports the fixed outer conductor and insulating sleeve to the eight-station turntable mechanism 3. The depth of the insulator is detected by the first rejection assembly 32, and defective products are removed. The center pin is assembled into the insulator by the third feeding assembly 33. First, the direction of the center pin is detected and defective products are removed. Then, the second riveting assembly 34 presses it into place, and then the depth and concentricity are detected and defective products are removed in sequence. Finally, the qualified products are removed by the unloading assembly 36.

[0026] like Figure 1 and Figure 2 As shown, in one specific embodiment of the improvement, both the first turntable assembly 11 and the second turntable assembly 31 include a base 111, a turntable 112 disposed above the base 111, and a disc 113 disposed above the turntable 112. The disc 113 is provided with a plurality of fixtures 114 along its outer edge for precisely fixing and limiting the outer conductor. Each fixture 114 is provided with at least two placement parts, and the disc 113 of the first turntable assembly 11 and the second turntable assembly 31 rotate counterclockwise and clockwise, respectively.

[0027] Specifically, the base 111 is detachably fixed to the platform. The turntable 112 is equipped with a servo motor that drives its rotation. The top of the turntable 112 is equipped with a cam with teeth-like features. The disc 113 has a circular hole with grooves around its bottom surface that engage with internal teeth. This allows the cam to be inserted into the circular hole, and the internal teeth to be embedded in the grooves, thus enabling the disc 113 to rotate. The top view area of ​​the disc 113 is larger than that of the turntable 112. The difference between the first turntable assembly 11 and the second turntable assembly 31 is that the first turntable assembly 11 is larger than the second turntable assembly 31. The disc 113 is equipped with four and eight fixtures 114 respectively. The fixtures 114 are detachably mounted onto the disc 113. For example, the inner side of the fixture 114 has a circular hole, and the disc 113 has screw holes, allowing for quick assembly and disassembly using screws. The detachable fixture structure supports rapid changeover, enabling flexible production and improving the adaptability of the equipment. Furthermore, each fixture 114 has two placement sections, the structure of which is adapted to the product, meaning each fixture 114 can be used simultaneously. The automated assembly production of two products, through synchronous operation at two workstations, can significantly improve automated assembly efficiency. Based on the first feeding component 12 being positioned on the front left side of the worktable, the second feeding component 13 being positioned on the left side of the worktable, and the first riveting component 14 being positioned on the right side of the second feeding component 13, the first feeding component 12 and the first riveting component 14 are arranged opposite each other. That is, the right side of the disc 113 of the first turntable assembly 11 corresponds precisely to the dual-station pressing mechanism 2. At this time, the disc 113 of the first turntable assembly 11 rotates counterclockwise. The process involves feeding the outer conductor, feeding and assembling the insulator, pressing the insulator into place inside the outer conductor, and finally having the first gripping component 41 transport the product to the dual-station crimping mechanism 2. In the eight-station turntable mechanism 3, the first rejection component 32 and the unloading component 36 are respectively located on the upper and lower sides of the rear end of the dual-station crimping mechanism 2, and the remaining components are arranged clockwise along the outer edge of the disc 113 of the second turntable component 31, so that the product can undergo multiple processes such as insulator depth detection and center pin assembly.

[0028] like Figure 1 and Figure 3 As shown, in one specific embodiment of the improvement, the first feeding assembly 12 includes a first vibrating plate 121, a first feeder 122 connected to the first vibrating plate 121, a positioning plate 123 placed at the front end of the first feeder 122, and a first driving member 124 disposed above the side of the positioning plate 123, so that the outer conductor is sequentially transferred between the first feeder 122, the positioning plate 123 and the first turntable assembly 11.

[0029] Specifically, a support frame is provided below the first vibratory plate 121. This support frame is located on the left side of the front end of the platform. A mounting base plate is connected to the side of the support frame. A support structure consisting of ribs and fixing plates is installed on the top of the base plate. The first drive unit 124 is installed on this support structure, and the bottom of the first feeder 122 is also connected to this support structure. The first feeder 122 is an adjustable direct vibration feeder. A connecting plate connected to the first vibratory plate 121 is provided on the first feeder 122. The connecting plate has two parallel feeding tracks and two receiving slots for the outer conductors to stay at the front end of the connecting plate. The feeding tracks are connected to the receiving slots. Several outer conductors are arranged sequentially on the feeding tracks. A sensor is provided on one side of the receiving slot. When the outer conductors in the receiving slots are transported to the positioning plate 123, the outer conductors on the feeding tracks can be continuously replenished. The positioning plate 123 and the connecting plate can be an integral structure. The front end of the positioning plate 123 is provided with two holes for placing the outer conductors and a mating hole. The device includes a finger cylinder whose inner shape is adapted to the outer conductor, allowing for clamping and limiting of the outer conductor. The first drive unit 124 includes a connecting plate, a linear module mounted on the connecting plate and driven back and forth along the length of the first feeder 122, and two long plates spaced apart on the linear module. Each long plate has two downward-facing finger cylinders, enabling the transport of the outer conductor from the two receiving slots to the positioning plate 123, and then from the positioning plate 123 to the disc 113 fixture 114 of the first turntable assembly 11, thus completing the automated feeding of the outer conductor. It is worth noting that the distances between the two long plates with finger cylinders, the distance between the receiving slot and the central hole of the positioning plate 123, and the distance between the central hole of the positioning plate 123 and the fixture 114 must all be matched. Furthermore, the finger cylinders on the two long plates can be independently adjusted and extend and retract vertically, ensuring the continuity and linkage of the outer conductor transport.

[0030] like Figure 1 and Figure 4 As shown, in one specific embodiment of the improvement, the second feeding assembly 13 includes a second vibrating plate 131, a second feeder 132 connected to the second vibrating plate 131, and a second driving member 133 placed above the side of the second feeder 132, so that the insulator is transferred from the second feeder 132 to the first turntable assembly 11.

[0031] Specifically, a support frame is provided below the second vibrating plate 131. This support frame is located on the front left side of the platform. A mounting base plate is connected to the side of the support frame. A support structure consisting of ribs and fixing plates is installed on the top of the base plate. The second drive unit 133 is installed on this support structure, and the bottom of the second feeder 132 is also connected to this support structure. The second feeder 132 is an adjustable direct vibration feeder. A connecting plate connected to the second vibrating plate 131 is provided on the second feeder 132. The connecting plate has two parallel feeding tracks and two receiving slots for insulators to stay at the front end of the connecting plate. The feeding tracks are connected to the receiving slots. The feeding tracks accommodate [materials]. Several insulators are arranged in sequence. A sensor is set on one side of the receiving slot. When the insulator in the receiving slot is transported to the positioning plate 123, the insulator in the feeding track can be continuously replenished. The second driving component 133 is provided with a connecting plate, a linear module set on the connecting plate and driven back and forth along the length direction of the second feeder 132, and a long plate set on the linear module. Two finger cylinders are designed on the long plate facing downward. The inner shape of the clamping block of the finger cylinder is adapted to the insulator, so as to correspond to the transportation of the insulator in the two receiving slots, realizing the transportation of the insulator from the receiving slot to the disc 113 fixture 114 of the first turntable assembly 11, thereby completing the automated feeding of the insulator.

[0032] like Figure 1 and Figure 9 As shown, in one specific embodiment of the improvement, the third feeding assembly 33 includes a third vibrating plate 331, a third feeder 332 connected to the third vibrating plate 331, a rotating member 333 placed at the front end of the third feeder 332, and a third driving member 334 placed above the rotating member 333, so that the center needle is sequentially transferred between the third feeder 332, the rotating member 333, and the second turntable assembly 31.

[0033] Specifically, a support frame is also provided below the third vibratory plate 331. This support frame is located on the front left side of the platform. A mounting base plate is connected to the side of the support frame. A support structure consisting of ribs and fixing plates is installed on the top of the base plate. The third drive unit 334 is installed on this support structure, and the bottom of the third feeder 332 is also connected to this support structure. The third feeder 332 is an adjustable direct vibration feeder. A connecting plate connected to the third vibratory plate 331 is provided on the third feeder 332. The connecting plate has two parallel feeding tracks and two receiving slots for the center needles to stop at the front end of the connecting plate. The feeding tracks are connected to the receiving slots. Several center needles are arranged sequentially on the feeding tracks. A sensor is provided on one side of the receiving slot. When the center needles in the receiving slots are transported to the rotating member 333, the center needles on the feeding tracks can be continuously replenished. The rotating member 333 and the connecting plate are separate structures. The top of the rotating member 333 is provided with two holes for placing center needles and a rotating cylinder with a mating hole. The rotary cylinder can rotate and limit the center pin, thereby adjusting the orientation of the center pin assembled into the insulator. The third drive unit 334 is provided with a connecting plate, a linear module mounted on the connecting plate and driven back and forth along the length of the third feeder 332, and two long plates spaced apart on the linear module. Each long plate is designed with two downward-facing finger cylinders. The inner shape of the clamping block of the finger cylinder is adapted to the center pin, thereby enabling the clamping and transport of the center pin in the two receiving slots, realizing the smooth transport of the center pin. The center pin is transported from the slot to the rotating component 333, and then from the rotating component 333 to the disc 113 fixture 114 of the second turntable assembly 31, thereby completing the automated feeding of the center pin. It is worth noting that the distance between the two long plates with finger cylinders, the distance between the receiving slot and the central hole of the rotating component 333, and the distance between the central hole of the rotating component 333 and the fixture 114 must all be matched, and the finger cylinders on the two long plates can be independently adjusted and extended and retracted, thereby achieving the continuity and linkage of the center pin transportation.

[0034] like Figure 1 and Figure 5 As shown, in one specific embodiment of the improvement, both the first riveting assembly 14 and the second riveting assembly 34 include a column 141, a mounting plate 142 disposed at the top of the column 141, and a plurality of riveting parts 143 mounted on the mounting plate 142 and disposed downwards, with a riveting pin 144 disposed at the bottom end of the riveting part 143.

[0035] Specifically, the column 141 has two supports and a base 111 mounted on the platform is connected to the bottom. The upper end of the column 141 is equipped with an adjustable locking block, which is detachably connected to the mounting plate 142. The height of the riveting component 143 can be adjusted by the locking block to improve the adaptability of production. The mounting plate 142 is an L-shaped fixed plate. The riveting component 143 includes a thin cylinder and a linear track mounted on the mounting plate 142, a slider slidably connected to the linear track, and a fixed block placed at the bottom of the slider. The top of the slider is connected to the thin cylinder. The riveting needle 144 is detachably mounted on the fixed block to improve the adaptability of rapid changeover production. The riveting needle 144 is a cylindrical needle with a diameter that decreases from top to bottom. The cylindrical needle at the end is adapted to the structure of the outer conductor or insulator, which can realize the automatic pressing of the insulator or center needle into place by the riveting needle 144. The pressing depth can be adjusted according to the products being produced.

[0036] like Figure 1 and Figure 6 As shown, in one specific embodiment of the improvement, the crimping assembly 21 includes a plurality of four-point crimping members 211 with a swing arm 212 and a sliding member 213 connected to the swing arm 212 and reciprocating back and forth.

[0037] Specifically, two of each of the four-point crimping component 211 and the sliding component 213 are provided and matched. The dual-station crimping mechanism 2 also includes a base 111, two parallel side support plates arranged above the base 111, and a fixed plate arranged above the support plates. The four-point crimping component 211 and the sliding component 213 are installed on the fixed plate. The four-point crimping component 211 includes a crimping positioning sleeve, a crimping claw seat arranged inside the crimping positioning sleeve, and a flange and an upper cover arranged sequentially above the crimping claw seat. The crimping claw seat is provided with four crimping claws in different positions and a reset pin arranged in conjunction with the crimping claws. The swing arm 212 is set on the crimping positioning sleeve and is an integral structure. The sliding component 213 includes a long guide block arranged on the outer side above the fixed plate, a short guide block arranged parallel to the long guide block, and a movable slide between the long guide block and the short guide block. The thin cylinder is located below the fixed block. The end of the thin cylinder is connected to the movable slider through a push block. The front end of the movable slider is connected to the swing arm 212. During operation, the thin cylinders on both sides below the fixed plate begin to retract and push the push block, thereby driving the movable slider to move horizontally forward along the guide rail. This causes the swing arm 212 to swing forward, so that the crimping positioning sleeve is subjected to a forward thrust and rotates. The internal wedge structure converts the axial thrust of the movable slider into a radial crimping force and drives the four crimping claws to retract towards the center at the same time, performing radial riveting on the outside of the outer conductor, so that the outer conductor and the insulator are tightly engaged and fixed. After the riveting is completed, the thin cylinder begins to move forward, the movable slider resets and drives the swing arm 212 to swing backward, the crimping positioning sleeve returns to the initial position, and the crimping claws are reset under the action of the reset pin.

[0038] like Figure 1 and Figure 6 As shown, in one specific embodiment of the improvement, the pressing component 22 includes a plurality of L-shaped pressing blocks 221 and a first driver connected to the pressing blocks 221 and capable of rotating and extending. The pressing blocks 221 have pressing columns 222 arranged with their front ends facing downwards, which cooperate with the four-point pressing members 211.

[0039] Specifically, the pressure block 221 is provided with two blocks, each corresponding to a four-point crimping component 211. The first driver includes a left-hand clamping cylinder and a right-hand clamping cylinder located below the fixed plate. The two pressure blocks 221 are respectively installed at the ends of the two cylinders, so that the pressure blocks 221 are positioned above the fixed plate. The structure of the pressure column 222 is adapted to the outer conductor. During operation, after the assembled outer conductor and insulator are placed in the crimping positioning sleeve and the radial and axial preliminary positioning is completed, the left-hand and right-hand clamping cylinders are activated and drive the pressure block 221 to rise, rotate 90 degrees, and fall. This causes the pressure column 222 to axially press the assembled outer conductor and insulator onto the crimping positioning sleeve, preventing jumps, offsets, or rotations during subsequent riveting, ensuring coaxiality, and improving product processing quality. After riveting is completed, the pressure block 221 rises, rotates 90 degrees in the opposite direction, and falls to achieve the reset of the pressure block 221.

[0040] like Figure 1 , Figure 7 and Figure 8 As shown, in one specific embodiment of the improvement, the first rejection component 32 includes a vertical plate 321, a second driver 322 disposed at the top of the vertical plate 321 and extending and retracting back and forth and up and down, a clamp 323 disposed at the front end of the second driver 322, and a depth detection component 324 disposed below the clamp 323.

[0041] Specifically, the bottom of the upright plate 321 is provided with an adjustment block installed on the platform. The second actuator 322 consists of a magnetically coupled rodless cylinder, a connecting block, and a sliding cylinder. The magnetically coupled rodless cylinder extends and retracts, and the sliding cylinder moves up and down. The clamp 323 is provided with two finger cylinders, which are used to clamp the upper outer end of the outer conductor. The depth detection component 324 includes a fixed plate fixed above the platform and vertically arranged, a sliding cylinder that moves up and down on the fixed plate, an L-shaped fixed block installed at the top of the sliding cylinder, and a detection component installed on the fixed block and vertically upward. It mainly consists of a pneumatic contact displacement sensor 3241 and a mounting frame for mounting the displacement sensor 3241. The displacement sensor 3241 has a probe at its end, with the center of the probe aligned with the lower center of the outer conductor. During operation, the finger cylinder first clamps the outer conductor in the fixture 114. After the slide cylinder starts, it drives the mounting frame to rise until the top surface of the mounting frame is against the bottom surface of the fixture 114. At this point, the probe is inserted into the outer conductor, with a depth range of 4.56-4.86 mm from the insulator to the top surface of the outer shell. The total height of the insulator and the acceptable range are then... The difference between the height of the outer conductor and the height of the insulator is used as the acceptable length for probe displacement detection. For example, if the height of the outer conductor is 300mm and the height of the insulator is 240mm, the maximum distance is 4.86mm. In this case, the acceptable length for probe displacement is 55.14-55.44mm. After the probe touches the insulator, the controller of the assembly machine analyzes the signal to determine whether the depth is acceptable. After the detection is completed, the second driver 322 runs to retrieve the product from the fixture 323 into the defective product box at the side and rear. It is worth noting that: the fixture 114 protrudes outward from the outer edge of the disc 113. The placement part is located on the outer side of the fixture 114, so that when the outer conductor is placed in the placement part, the bottom surface of the outer conductor is flush with the bottom surface of the fixture 114. However, the thickness of the outer side of the fixture 114 is less than the thickness of the inner side to accommodate the height of the outer conductor. In addition, since the probe is inserted for detection from bottom to top, if the above-mentioned qualified length is set exactly, there is a risk of collision with the fixture 114. Therefore, it can be increased by 2-5mm. In this case, the initial height of the probe should also be reduced by 2-5mm, and the qualified length should also be increased by 2-5mm.

[0042] like Figure 1 , Figure 10 and Figure 11 As shown, in one specific embodiment of the improvement, the second rejection component 35 includes a direction detection component 351, a depth detection component 352 and a concentricity detection component 353 arranged in sequence to detect and remove defective products by center pin. The direction detection component 351 and the concentricity detection component 353 are respectively provided with a lens barrel 3511 and a lens 3531.

[0043] Specifically, the orientation detection component 351, depth detection component 352, and concentricity detection component 353 are all composed of a detection unit and a defective product removal unit. For the orientation detection component 351, the defective product removal unit is located below and inside the detection unit. The detection unit includes a fixing column, a light source plate and a camera plate installed in the middle and upper parts of the fixing column. The light source plate and camera plate are fixed by an adjustable locking block. The end of the light source plate has a downward-facing light source, and the end of the camera plate has a camera. The end of the camera is designed to face downwards and be aimed at the lens barrel 3511 for product imaging. The light source is located below the lens barrel 3511, and the lens 3... The center of 531 and the center of the light source are coaxially arranged in the vertical direction. The defective product removal part includes a magnetically coupled rodless cylinder that moves back and forth, a slide cylinder that is set at the end of the magnetically coupled rodless cylinder and moves up and down, and a finger cylinder that is set at the end of the slide cylinder. During operation, after the fixture 114 reaches the designated position, the light source is turned on to provide supplementary lighting, and the lens barrel 3511 of the camera takes a picture. If the camera captures the center needle image and the controller of the assembly machine finds that the direction is incorrect, the magnetically coupled rodless cylinder and the slide cylinder are activated in sequence, and the product is picked up by the finger cylinder and transported to the defective product box on the side below.

[0044] In addition, the detection section and defective product removal section in the depth detection component 352 of the center pin are similar or similar in structure to the first rejection component 32 of the insulator, and will not be described in detail here. The only difference is that the acceptable depth range of the center pin is 0.21-0.51mm from the center pin to the top surface of the outer shell. The acceptable length of the probe displacement and the setting height can be adjusted according to this acceptable range.

[0045] For the concentricity inspection part 353, the defective product removal part is placed above the inspection part, so that the fixture 114 is placed between the inspection part and the defective product inspection part. The inspection part includes an L-shaped connecting block, a linear module installed on the connecting block and moving up and down, a fixing block installed on the upper part of the linear module, and a camera installed on the fixing block. The camera is designed with an upward-facing lens 3531, and the lens 3531 extends out after passing through the platform. Above the lens 3531 is an upward-facing circular light source. The center of the lens 3531 and the center of the light source are coaxially arranged in the vertical direction. The defective product removal part has a similar or identical structure to the defective product removal part of the inspection part 351 mentioned above, and will not be described in detail here. During operation, after the fixture 114 reaches the designated position, the light source is turned on to provide supplementary lighting. The camera takes pictures through the lens 3531. The controller of the assembly machine analyzes the images. If the concentricity deviation does not exceed 0.1mm, it is judged as a defective product and removed through the defective product removal process, and transported to the defective product box on the side below.

[0046] like Figure 1 As shown, in one specific embodiment of the improvement, the feeding assembly 36 includes a third driver 361 that extends forward and backward and vertically, and a storage frame 362 disposed below the third driver 361.

[0047] Specifically, the structure of the third actuator 361 is similar to or the same as that of the second actuator 322. Both consist of a magnetically coupled rodless cylinder that moves back and forth, a connecting block, and a slide cylinder that moves up and down. Similarly, two clamps 323 are designed at the end of the slide cylinder. The clamps 323 are finger cylinders used to grip the products. It is worth noting that the products flowing into the unloading component 36 are all qualified products after several inspection processes. Therefore, the qualified products can be directly transported to the storage box 362.

[0048] like Figure 1 and Figure 12 As shown, in one specific embodiment of the improvement, the transfer mechanism 4 further includes a fourth driver 43 for lateral movement and a linkage frame 44 disposed on the side of the fourth driver 43, and the first gripping component 41 and the second gripping component 42 are both mounted on the linkage frame 44.

[0049] Specifically, the fourth drive 43 is a linear module with a cable chain. The linear module has a fixed frame, and two fixed blocks are installed on the lower part of the fixed frame. The first gripping component 41 and the second gripping component 42 are respectively installed on the two fixed blocks. The first gripping component 41 and the second gripping component 42 each include a slide cylinder that moves up and down and two finger cylinders designed on the slide cylinder for gripping products. This allows the first gripping component and the second gripping component to move together in the horizontal direction, but can be raised and lowered separately in the vertical direction to grip, thus improving the adaptability of production.

[0050] Workflow: The operator adds the corresponding materials (outer conductor, insulator, and center pin) to the first, second, and third vibratory feeders in the prescribed quantities. After the materials are added, the assembly machine adjusts the data and starts. The first turntable assembly 11 of the four-station turntable mechanism 1 rotates counterclockwise and passes sequentially through the first feeding assembly 12, the second feeding assembly 13, the first riveting assembly 14, and the first gripping assembly 41, so that the outer conductor is fixed in place in the fixture 114, and the insulator is transferred to the inside of the outer conductor. Then, the assembled outer conductor and insulator are pressed into place. Next, the assembled semi-finished product is transferred from the first turntable assembly 11 to the crimping assembly 21. The crimping assembly 21 and the pressing assembly 22 work together to create riveting points on the outside of the outer conductor, causing the inner wall of the outer conductor to be concave inward. The insulator is fixed in place, and then the riveted semi-finished product is transferred to the fixture 114 of the second turntable assembly 31 in the eight-station turntable mechanism 3 by the second gripping assembly 42. At this time, the second turntable assembly 31 rotates clockwise and passes through the first rejection assembly 32, the third feeding assembly 33, the second riveting assembly 34, the second rejection assembly 35, and the unloading assembly 36 in sequence. The process includes insulator depth detection and defective product removal, assembly of the center pin with the riveted semi-finished product, center pin direction detection and defective product removal, pressing the center pin into place in the riveted semi-finished product, center pin depth detection and defective product removal, center pin concentricity detection and defective product removal, and finally, the qualified product is transported to the storage box 362 by the unloading assembly 36. This achieves automated production and saves production labor.

[0051] Finally, it should be noted that the above description is only an implementation method of this application and does not limit the patent scope of this application. Any equivalent structural or procedural changes made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
