Description

Technical Field

[0001] This application relates to the field of automated assembly equipment technology, and in particular to a quick-connect pipe fitting clamp assembly device. Background Technology

[0002] Quick-connect fittings are a common and crucial component in pipeline connections, such as those used for agricultural irrigation. One type of quick-connect fitting for agricultural irrigation typically comprises five parts: the quick-connect body, clamps, springs, a movable sleeve, and a nut. The assembly structure of the quick-connect body and clamps is as follows: the outer circumference of the quick-connect body has several (e.g., three) grooves, and the inner wall of the movable sleeve has several slots that mate with the sidewalls of the grooves. During assembly, the clamps are inserted into the corresponding grooves on the outer circumference of the quick-connect body.

[0003] Currently, the mainstream assembly method for quick-connect fittings still relies heavily on manual operation. Since multiple clamps and slots are involved in the assembly, operators need to install multiple clamps into their corresponding slots individually. Because the clamps are small and irregularly shaped, manual assembly is inefficient. Furthermore, since the clamps can still move freely after being installed in the slots, care must be taken to ensure the previous clamp does not dislodge from its slot before assembling the next one; otherwise, defective products will be produced. Manual assembly typically uses only simple tools, such as placing the quick-connect fitting body on a rotating platform. After installing one clamp, the platform is rotated to align the next empty slot with the intended assembly position before installation. During rotation, the assembled clamp may fall out of its slot due to movement, requiring reassembly. Throughout the assembly process, the alignment of parts, individual insertion, and position checks are all done manually by visual inspection, resulting in low assembly efficiency, high labor intensity, and poor assembly consistency. This directly affects the product's pass rate and reliability, making it difficult to meet the demands of large-scale, automated production.

[0004] Based on this, those skilled in the art have proposed a quick-connect fitting clamp assembly device, which provides a new solution to the above-mentioned technical problems. Summary of the Invention

[0005] To address the problems mentioned in the background art, this application provides a quick-connect pipe fitting clamp assembly device.

[0006] The quick-connect fitting clamp assembly equipment provided in this application adopts the following technical solution: A quick-connect fitting clamp assembly device for assembling the fitting body and clamp, including... Workbench; A transfer mechanism, installed on the workbench, includes a rotary drive and a transfer disk driven to rotate by the rotary drive. The outer edge of the transfer disk is provided with a plurality of transfer carriers along its circumference. Each of the transfer carriers is used to carry the connector body to be assembled. A fixing disk is provided above the transfer disk and the fixing disk is fixedly installed on the workbench. The main body feeding mechanism is located on the outer periphery of the transfer tray and is used to feed the connector body onto the transfer carrier; A number of card head feeding and assembly mechanisms are arranged sequentially along the outer periphery of the transfer disc downstream of the main body feeding mechanism. Each card head feeding and assembly mechanism is used to feed the card head and assemble the card head into the corresponding card slot of the connector body, and is used to press out a limiting groove on the side wall of the card slot to form a radial limit on the card head located in the card slot. The slot displacement mechanism is located between two adjacent card head feeding and assembly mechanisms. After each card head assembly is completed, it drives the corresponding transfer carrier to rotate relative to the transfer plate by a predetermined angle so that the next empty slot of the connector body is aligned with the preset assembly station.

[0007] By adopting the above technical solution, a transfer tray drives several transfer carriers to pass sequentially through the main body feeding mechanism and several clamp feeding and assembly mechanisms, realizing automatic feeding of the connector body and automatic one-by-one assembly of the clamps. At the same time, through the clamp slot displacement mechanism, the transfer carrier is displaced relative to the transfer tray after completing the assembly of one clamp, causing the next empty clamp slot to rotate to the assembly station. The assembled clamps rotate synchronously with the transfer carrier, avoiding the problem of assembled clamps falling out of the clamp slot due to rotating the connector body to find the next empty clamp slot in the existing manual assembly or simple rotating chassis assembly methods. This improves assembly efficiency and assembly qualification rate, and reduces manual labor intensity.

[0008] Optionally, it also includes a detection mechanism and a material handling mechanism. The detection mechanism is located downstream of the plurality of clamp head feeding and assembly mechanisms and is used to detect whether the clamp heads have been assembled in the plurality of clamp slots of the connector body. The material handling mechanism is located downstream of the detection mechanism and is used to remove the assembled connector body from the transfer carrier. By adopting the above technical solutions, automatic inspection and automatic unloading after assembly are achieved, further reducing manual intervention and improving the automation level of assembly equipment.

[0009] Optionally, the transfer vehicle includes: The mounting base is fixedly installed on the transfer tray; A transfer support fixture is slidably connected to the inner side of the mounting base. The outer periphery of the transfer support fixture is provided with a plurality of receiving grooves, and each of the receiving grooves corresponds one-to-one with a plurality of the slots of the connector body. A return spring is sleeved on the outside of the bottom of the transfer support fixture, and the two ends of the return spring abut against the bottom of the transfer plate and the bottom of the transfer support fixture, respectively. By adopting the above technical solution, the receiving groove provides clearance space for the part of the chuck located inside the connector body after assembly, avoiding interference between the chuck and the transfer support fixture during assembly; the return spring enables the transfer support fixture to have elastic return capability along the axial direction, which facilitates the automatic return of the transfer support fixture after axial displacement during the displacement process.

[0010] Optionally, the slot displacement mechanism includes: The mounting bracket is fixedly installed on the fixed plate; A downward-pressing cylinder is mounted on top of the mounting bracket; A pressure head, installed at the output end of the lower pressure cylinder, is used to press the top of the connector body to axially limit its movement; A lifting frame is slidably mounted on the workbench and is arranged vertically opposite to the pressure head; the transfer plate is located between the pressure head and the lifting frame. A lifting drive cylinder is installed on the workbench, and its output end is fixedly connected to the lifting frame for driving the lifting frame to lift. A rotary displacement drive cylinder is installed on the top of the lifting frame; A displacement drive block is installed at the output end of the rotary displacement drive cylinder, and a displacement retainer is provided on the displacement drive block; The bottom of the transfer support fixture is provided with a displacement drive groove, which is adapted to and engaged with the displacement clip; when the lifting drive cylinder drives the lifting frame to rise, the displacement clip is engaged into the corresponding displacement drive groove, and the rotating displacement drive cylinder drives the displacement drive block to rotate the transfer support fixture relative to the transfer plate by the predetermined angle. By adopting the above technical solution, when the lifting drive cylinder drives the lifting frame to rise, the displacement clip is inserted into the corresponding displacement drive groove. Rotating the displacement drive cylinder can drive the displacement drive block to drive the transfer support fixture to rotate relative to the transfer plate by a predetermined angle, realizing the automatic displacement of the connector body after completing the assembly of a clip. At the same time, the pressing cylinder uses the pressing head to axially limit the top of the connector body, ensuring that the connector body will not move axially during the displacement process, thus improving the displacement accuracy and reliability.

[0011] Optionally, the body feeding mechanism includes: The connector body vibration feeding mechanism is used for automatic feeding of the connector body; A centrifugal slot finding and alignment mechanism is located at the output end of the vibration feeding mechanism of the connector body, and is used to swing and adjust the slot position of the connector body after feeding to a preset position. The main body feeding and conveying mechanism is located on one side of the centrifugal grooving and straightening mechanism. It is used to transport the joint body from the joint body vibration feeding mechanism to the centrifugal grooving and straightening mechanism, and to transport the straightened joint body from the centrifugal grooving and straightening mechanism to the transfer carrier. By adopting the above technical solution, the initial angle position of the slot after the connector body is vibrated and fed is random. The centrifugal slot finding and straightening mechanism can automatically adjust the slot to a preset angle position that is convenient for subsequent clamp assembly, eliminating the need for manual alignment and improving feeding efficiency and assembly accuracy.

[0012] Optionally, the centrifugal grooving and alignment mechanism includes: The mounting bracket is fixedly installed on the workbench; The slotting fixture is rotatably mounted on the mounting bracket; A drive rack and a transmission gear are provided, wherein the transmission gear is fixedly installed at the bottom of the grooving fixture, and the drive rack is meshed with the transmission gear. A centrifugal drive cylinder, mounted on the mounting bracket, has its output end connected to the drive rack, driving the drive rack to perform linear motion, thereby rotating the transmission gear and thus rotating the grooving fixture. The outer wall of the grooving fixture has several mounting slots, each containing a centrifugal swing rod. The centrifugal swing rod is L-shaped, with one end being a grooving protrusion and the other end being a centrifugal swing end. The grooving protrusion is located inside the mounting slot, and the centrifugal swing end is located outside the mounting slot. When the grooving fixture rotates, the centrifugal swing rod, under centrifugal force, causes the centrifugal swing end to swing downwards, and the grooving protrusion tends to open outwards. When the grooving protrusion rotates to correspond with the slot position of the connector body, the grooving protrusion engages in the slot, causing the connector body and the grooving fixture to rotate synchronously. By adopting the above technical solution, when the grooving fixture rotates, the centrifugal swing arm swings downward under the action of centrifugal force, and the grooving protrusion tends to open outward. When the grooving protrusion rotates to correspond to the slot position of the connector body, the grooving protrusion is inserted into the slot, which drives the connector body and the grooving fixture to rotate synchronously, thereby realizing the automatic positioning of the slot angle position of the connector body. The structure is simple and the operation is reliable.

[0013] Optionally, a pair of detection sensors are provided on both sides of the top of the mounting frame to detect the height position of the centrifugal swing end, so as to determine whether the groove-finding protrusion is engaged in the groove; if it is detected that the groove-finding protrusion is not engaged in the groove, the centrifugal drive cylinder drives the groove-finding fixture to reset and then drives the groove-finding fixture to rotate again. By adopting the above technical solution, when the grooving protrusion is not engaged in the slot, the position of the centrifugal swing end is higher; when the grooving protrusion is engaged in the slot, the position of the centrifugal swing end is lower. By detecting the position change of the centrifugal swing end by the detection sensor, it can be indirectly determined whether the grooving protrusion is engaged in the slot. If it is detected that the grooving protrusion is not engaged in the slot, the centrifugal drive cylinder drives the grooving fixture to reset and then drives the grooving fixture to rotate again, repeating the grooving action. This realizes the automatic detection of the grooving result and the automatic retry after the grooving failure, ensuring the reliability of the joint body angle adjustment.

[0014] Optionally, each of the said card head feeding and assembly mechanisms includes: A chuck vibration feeding mechanism is used for automatic feeding of the chuck. A cutting mechanism is located at the output end of the chuck vibration feeding mechanism and is used to cut and separate the chuck after feeding. The chuck loading and unloading mechanism is used to grab the cut chuck and transfer it to the alignment position near the chuck slot of the connector body; A pushing mechanism, located at the output end of the chuck loading and unloading mechanism, includes a pushing frame. The pushing frame is provided with a chuck pushing strip and a limiting protrusion pressing plate. The width of the chuck pushing strip is smaller than the width of the chuck groove, and it is used to push the chuck held by the chuck loading and unloading mechanism into the chuck groove. The limiting protrusion pressing plate is located at the bottom of the chuck pushing strip, and its width is larger than the width of the chuck groove, and it is used to press out the limiting groove on the side wall of the chuck groove after the chuck is pushed into the chuck groove. By adopting the above technical solution, a fully automated process is realized, including automatic feeding, cutting, gripping and transferring of the chuck head, and pushing it into the chuck slot for assembly. At the same time, the limiting protrusion extrusion plate is used to press out the limiting groove simultaneously after the chuck head is assembled in place. Assembly and limiting can be completed in one action, which improves assembly efficiency.

[0015] Optionally, the chuck loading and unloading mechanism includes a mounting frame, a rotary loading and unloading drive cylinder rotatably mounted on the mounting frame, a mounting plate mounted on the output end of the rotary loading and unloading drive cylinder, a chuck loading and unloading cylinder mounted on the mounting plate, and a chuck loading and unloading gripper mounted on the output end of the chuck loading and unloading cylinder; the pushing mechanism further includes a chuck assembly cylinder mounted on the chuck loading and unloading gripper, and the pushing frame is mounted on the output end of the chuck assembly cylinder; the rotary loading and unloading drive cylinder is used to drive the chuck loading and unloading gripper to rotate and switch between a vertical state and a horizontal state, so that the chuck loading and unloading gripper first grabs the chuck after cutting in a vertical state, and then rotates to a horizontal state and aligns with the chuck slot; By adopting the above technical solution, the rotary pick-and-place drive cylinder is used to drive the chuck pick-and-place gripper to rotate and switch between vertical and horizontal states, so that the chuck pick-and-place gripper first grabs the cut chuck in the vertical state, and then rotates to the horizontal state and aligns with the chuck slot, realizing the automatic conversion of the chuck from the vertical gripping posture to the horizontal assembly posture, adapting to the angular differences in the spatial arrangement of the cutting station and the assembly station.

[0016] Optionally, a positioning cylinder is installed on the fixed plate opposite to the pushing mechanism. A positioning gripper is installed at the output end of the positioning cylinder. A vertical limiting protrusion is provided at the end of the positioning gripper, and a pressure-bearing inclined surface is provided at the bottom of the vertical limiting protrusion. During the assembly of the clamping head, the two grippers of the positioning gripper clamp the side walls on both sides of the slot to be assembled with the connector body for circumferential positioning. At the same time, the two vertical limiting protrusions abut against the upper part of the side walls of the slot through the pressure-bearing inclined surface for axial positioning. By adopting the above technical solution, during the assembly of the chuck head, the two jaws of the positioning gripper clamp the side walls on both sides of the slot to be assembled with the connector body for circumferential positioning. At the same time, the two vertical limiting protrusions abut against the upper sides of the slot through the pressure-bearing inclined surfaces for axial positioning. This achieves dual circumferential and axial positioning of the connector body during the chuck head is pushed into the slot, ensuring the accuracy of the chuck head assembly position and avoiding assembly misalignment.

[0017] In summary, this application includes at least one of the following beneficial technical effects: This invention uses a transfer mechanism to drive several transfer carriers through a main body feeding mechanism, several clamp feeding and assembly mechanisms, a testing mechanism, and a material unloading and handling mechanism in sequence. This achieves fully automated assembly line operation of joint body feeding, clamp feeding and assembly, assembly testing, and finished product unloading. Compared with manual assembly, this invention greatly improves assembly efficiency and reduces labor intensity. This invention sets up a slot displacement mechanism between two adjacent card head feeding and assembly mechanisms, so that the connector body is displaced relative to the transfer plate after one card head is assembled, causing the next empty slot to rotate to the assembly station. Meanwhile, the assembled card head rotates synchronously with the transfer carrier without relative rotation, thus avoiding the phenomenon of assembled card heads falling out of the slot due to displacement, and improving assembly consistency and product qualification rate.

[0018] This invention utilizes a centrifugal slot-finding and alignment mechanism, which uses centrifugal force to drive a centrifugal pendulum to automatically find and engage with the slot of the connector body. This achieves automatic positioning of the slot angle of the connector body without the need for manual alignment, further improving the degree of automation and assembly accuracy.

[0035] To enable those skilled in the art to better understand the technical solution of the present invention, the following will be described in conjunction with the accompanying drawings. Figure 1-15 The present invention will now be described in further detail.

[0036] Reference Figures 1 to 3 This application provides a quick-connect fitting clamp assembly device for assembling the fitting body 1 and the clamp 2 into a quick-connect fitting assembly.

[0037] The assembly equipment includes a workbench 90, and a transfer mechanism 80 for transferring the connector body 1 is mounted on the top of the workbench 90. The transfer mechanism 80 includes a rotary drive 803 mounted on the top of the workbench 90, and a transfer disk 801 mounted on the output end of the rotary drive 803. The rotary drive 803 drives the transfer disk 801 to circulate between various workstations. Several transfer carriers 810 are provided along the outer edge of the transfer disk 801, which are used as carriers during the assembly process of the connector body 1 and the clamp 2. The transfer carrier 810 includes a mounting base 811 fixedly mounted on the transfer disk 801, and a transfer support fixture 812 slidably connected to the inner side of the mounting base 811. Several receiving grooves 813 are provided on the outer periphery of the transfer support fixture 812. A return spring 814 is sleeved on the outer side of the bottom of the transfer support fixture 812, and the two ends of the return spring 814 abut against the bottom of the transfer disk 801 and the bottom of the transfer support fixture 812, respectively. A fixed plate 802 is provided above the transfer tray 801, and the fixed plate 802 is fixedly installed on the top of the workbench 90. The following workstations are arranged sequentially along the outer periphery of the transfer tray 801.

[0038] (a) Body loading station The main body feeding station is used to feed the connector body 1, including the connector body vibration feeding mechanism 10, the centrifugal groove finding and straightening mechanism 70 and the main body feeding and conveying mechanism 20.

[0039] Reference Figure 4 The connector body vibration feeding mechanism 10 is used to automatically feed the connector body 1. It includes a body vibration feeding plate assembly 101, a body cutting cylinder 103 installed at the output end of the body vibration feeding plate assembly 101, and a body cutting fixture 102 installed at the output end of the body cutting cylinder 103. The body cutting fixture 102 is slidably installed at the end of the body vibration feeding plate assembly 101. The body vibration feeding plate assembly 101 transports the connector body 1 to the inside of the body cutting fixture 102. Then, the body cutting cylinder 103 drives the body cutting fixture 102 to slide to complete the cutting work.

[0040] A centrifugal grooving and alignment mechanism 70 is located at the output end of the joint body vibration feeding mechanism 10, and is used to swing and adjust the joint body 1 to a preset position after feeding. (Refer to...) Figures 4 to 6The centrifugal slotting and alignment mechanism 70 includes a fifth mounting frame 701 fixedly mounted on the top of the workbench 90 and located on one side of the main cutting fixture 102. A slotting fixture 702 is rotatably mounted on the fifth mounting frame 701. A transmission gear 708 is fixed to the bottom of the slotting fixture 702. A drive rack 707 is meshed with one side of the transmission gear 708. A centrifugal drive cylinder 706 is mounted on the top side of the fifth mounting frame 701. The output end of the centrifugal drive cylinder 706 is connected to the drive rack 707. Several mounting slots 703 are formed on the outer wall of the slotting fixture 702. A centrifugal swing rod 704 is rotatably mounted on the inner side of each mounting slot 703. The centrifugal swing rod 704 is L-shaped in general. One end is a slotting protrusion 7041, which is set almost vertically inside the mounting slot 703. The other end is a centrifugal swing end 7042, which is set almost horizontally and freely. A pair of second detection sensors 705 are provided on both sides of the top of the fifth mounting bracket 701 to detect the horizontal height position of the centrifugal swing end 7042.

[0041] When the connector body 1 is placed on the grooving fixture 702, there may be an angular deviation between the position of the slot 11 on the connector body 1 and the position of the grooving protrusion 7041. At this time, the centrifugal drive cylinder 706 is activated, driving the drive rack 707 to move linearly. The drive rack 707 drives the transmission gear 708 to rotate, which in turn drives the grooving fixture 702 to rotate. When the grooving fixture 702 rotates, it rotates relative to the connector body 1. At the same time, the grooving fixture 702 drives the centrifugal swing rod 704 to rotate. Under the action of centrifugal force, the centrifugal swing end 7042 swings downward, and the grooving protrusion 7041 tends to open outward. When the grooving fixture 702 rotates until the position of the grooving protrusion 7041 corresponds to the position of the slot 11, the grooving protrusion 7041 is engaged in the slot 11 under the action of centrifugal force, thereby driving the connector body 1 and the grooving fixture 702 to rotate synchronously. When the drive rack 707 moves to the preset position, the slot 11 of the connector body 1 rotates to the preset position that facilitates the assembly of the clip 2.

[0042] It should be noted that when the grooving protrusion 7041 is not engaged in the slot 11, the centrifugal swing end 7042 is positioned higher; when the grooving protrusion 7041 is engaged in the slot 11, the centrifugal swing end 7042 is positioned lower. The position of the centrifugal swing end 7042 is detected by the second detection sensor 705 to determine whether the grooving protrusion 7041 has engaged in the slot 11. If the detection result indicates that it is not engaged in the slot 11, the centrifugal drive cylinder 706 drives the drive rack 707 to reset and then drives the grooving fixture 702 to rotate again, repeating the above grooving action until the grooving protrusion 7041 is engaged in the slot 11.

[0043] The main body loading and handling mechanism 20 is located on one side of the fifth mounting frame 701, including a first horizontal drive component 201, a first vertical drive component 202, and main body loading pneumatic grippers 203 installed at the output ends of the first horizontal drive component 201 and the first vertical drive component 202. There are two main body loading pneumatic grippers 203. The first horizontal drive component 201 and the first vertical drive component 202 cooperate to drive the main body loading pneumatic grippers 203 to perform horizontal and vertical displacement movements, so that the two main body loading pneumatic grippers 203 simultaneously grab the connector body 1 on the main body cutting fixture 102 and the slotting fixture 702, respectively, and place the connector body 1 on the main body cutting fixture 102 onto the slotting fixture 702. At the same time, the connector body 1, which was originally located on the slotting fixture 702 and has been aligned, is placed onto the transfer support fixture 812 of the transfer carrier 810. At this time, the plurality of receiving slots 813 on the transfer support fixture 812 correspond one-to-one with the plurality of slots 11 on the connector body 1. Since part of the chuck 2 will be located inside the connector body 1 after assembly, the receiving groove 813 is used to provide clearance space for it when assembling the chuck 2.

[0044] (ii) Card head loading and assembly station Reference Figures 7 to 9 Several clamping head feeding and assembly mechanisms 30 are provided along the outer periphery of the transfer tray 801. These mechanisms are used to feed clamping heads 2 and assemble them into the clamping slots 11 of the connector body 1. At the same time, limiting grooves are pressed out on the side wall of the clamping slots 11 to form a radial limit on the clamping heads 2 located inside the clamping slots 11. A clamping slot displacement mechanism 40 is provided between each two adjacent clamping head feeding and assembly mechanisms 30. This mechanism is used to displace the connector body 1 on the transfer carrier 810 after each clamping head 2 is assembled.

[0045] Each chuck loading assembly mechanism 30 includes a chuck vibrating loading tray assembly 301. A cutting mounting bracket 309 is provided at the end of the chuck vibrating loading tray assembly 301. A chuck cutting fixture 311 is slidably mounted on the inner side of the cutting mounting bracket 309 for cutting the loaded chucks 2. A chuck cutting cylinder 310 is mounted on one side of the cutting mounting bracket 309, and the output end of the chuck cutting cylinder 310 is connected to the chuck cutting fixture 311.

[0046] A second mounting bracket 302 is provided on one side of the cutting mounting bracket 309. A rotary material handling drive cylinder 303 is mounted on the second mounting bracket 302. A first mounting plate 304 is mounted on the output end of the rotary material handling drive cylinder 303. A chuck material handling cylinder 305 is mounted on the first mounting plate 304. A chuck material handling gripper 306 is mounted on the chuck material handling gripper 305. A chuck assembly cylinder 307 is mounted on the output end of the chuck assembly cylinder 306. A pusher frame 308 is mounted on the output end of the chuck assembly cylinder 307. The pusher frame 308 includes a chuck pusher bar 3081 and a limiting protrusion extrusion plate 3082. The width of the chuck pusher bar 3081 is slightly smaller than the width of the chuck groove 11. It is used to push the chuck 2, which is gripped by the chuck pick-and-place pneumatic gripper 306, into the chuck groove 11 for assembly. The width of the end of the limiting protrusion extrusion plate 3082 is slightly larger than the width of the chuck groove 11. It is used to press out a limiting groove on the side wall of the chuck groove 11 after the chuck 2 is pushed into the chuck groove 11, so as to form a radial limit on the chuck 2 located inside the chuck groove 11.

[0047] Reference Figures 10 to 12 A positioning cylinder 312 is installed on the fixed plate 802, opposite to the pusher frame 308. A positioning gripper 313 is installed at the output end of the positioning cylinder 312, used to position the connector body 1 during the assembly of the clamping head 2. The end of the positioning gripper 313 is provided with a vertical limiting protrusion 314, and the bottom of the vertical limiting protrusion 314 is inclined with a pressure-bearing slope 315. When positioning the connector body 1, the two positioning grippers 313 clamp the two side walls of the mounting slot 11 for circumferential positioning; simultaneously, the two vertical limiting protrusions 314 abut against the upper sides of the two side walls of the slot 11 through the pressure-bearing slope 315 for axial positioning.

[0048] After the main body loading and conveying mechanism 20 loads the connector body 1 onto the transfer carrier 810, the transfer mechanism 80 starts and transfers the connector body 1 to the corresponding station of the first clamping head loading and assembly mechanism 30. At this time, the positioning cylinder 312 starts, driving the two positioning claws 313 to clamp the two side walls of the clamping slot 11 for positioning; at the same time, the clamping head cutting cylinder 310 starts, pushing the clamping head cutting fixture 311 to push the clamping head 2 located inside it forward and complete the cutting. Then the rotation picking and unloading driving cylinder 303 starts, driving the first mounting plate 304 to rotate 90 degrees, so that the clamping head picking and unloading claw 306 is in a vertical state; then the clamping head picking and unloading cylinder 305 starts, driving the clamping head picking and unloading claw 306 to descend and grab the clamping head 2 located inside the clamping head cutting fixture 311. At this time, the clamping head push bar 3081 is located above the clamping head 2. Then, the rotary loading and unloading drive cylinder 303 drives the chuck loading and unloading cylinder 305, the chuck loading and unloading gripper 306, and the chuck assembly cylinder 307 to rotate 90 degrees as a whole, so that the chuck loading and unloading gripper 306 is turned to a horizontal position and aligned with the slot 11 of the connector body 1. Then, the chuck loading and unloading cylinder 305 is activated, driving the chuck loading and unloading gripper 306 to move towards the slot 11, so that the chuck 2 moves to the alignment position near the slot 11. Then, the chuck assembly cylinder 307 is activated, driving the pusher 308 to move forward, and the chuck pusher bar 3081 pushes the chuck 2 held by the chuck loading and unloading gripper 306 into the corresponding slot 11. At the same time, the limiting protrusion pressing plate 3082 presses out a limiting groove on the side wall of the slot 11 to form a radial limit on the chuck 2, completing the assembly of the first chuck 2.

[0049] (III) Card slot displacement station After the first clamp head 2 is assembled, it is located inside the corresponding receiving slot 813. At this time, when the transfer support fixture 812 rotates, the connector body 1 will rotate synchronously. The transfer mechanism 80 drives the transfer carrier 810 to rotate one station, reaching the first clamp slot positioning mechanism 40. (Refer to...) Figure 10 and Figure 11 The slot displacement mechanism 40 includes a third mounting bracket 401 mounted on a fixed plate 802. A pressing cylinder 402 is mounted on the top of the third mounting bracket 401, and a pressing head 403 is provided at the output end of the pressing cylinder 402. A lifting frame 404 is slidably mounted on the worktable 90, opposite to the lower part of the pressing head 403. The transfer plate 801 is located between the pressing head 403 and the lifting frame 404. A rotary displacement drive cylinder 406 is mounted on the top of the lifting frame 404. A displacement drive block 407 is mounted on the output end of the rotary displacement drive cylinder 406. A displacement locking strip 408 is provided on the displacement drive block 407. A displacement drive groove 815 adapted to engage with the displacement locking strip 408 is provided at the bottom of the transfer support fixture 812. A lifting drive cylinder 405 is mounted on the worktable 90, and the output end of the lifting drive cylinder 405 is fixedly connected to the lifting frame 404.

[0050] When the connector body 1, after the first clamp 2 has been assembled, moves to below the pressure head 403, the pressing cylinder 402 is activated, pressing the top of the connector body 1 against the pressure head 403 to axially limit its movement. The lifting drive cylinder 405 is activated, driving the lifting frame 404 to rise as a whole, causing the positioning clamp 408 to engage in the positioning drive groove 815. Subsequently, the rotational positioning drive cylinder 406 is activated, driving the positioning drive block 407, together with the transfer support fixture 812, to rotate by a predetermined angle (e.g., 120 degrees), so that the next empty clamp slot 11 on the connector body 1 corresponds to the position where the next clamp 2 will be assembled. After the positioning is completed, the lifting drive cylinder 405 and the pressing cylinder 402 are reset, causing the positioning clamp 408 and the pressure head 403 to disengage from the transfer carrier 810.

[0051] Subsequently, the transfer mechanism 80 drives the displaced connector body 1 to rotate one station and reach the second clamping head assembly mechanism 30 to assemble the second clamping head 2. After the second clamping head 2 is assembled, it passes through the next clamping slot displacement mechanism 40 to displace again and reaches the third clamping head assembly mechanism 30 to assemble the third clamping head 2.

[0052] (iv) Testing station Reference Figure 13 and Figure 14 After all three clips 2 are assembled, the transfer mechanism 80 drives the connector body 1 to rotate one station and reach the detection mechanism 50. The detection mechanism 50 includes a fourth mounting bracket 501 mounted on a fixed plate 802. Three first detection sensors 502 are mounted on the fourth mounting bracket 501. The output ends of the three first detection sensors 502 correspond to the positions of the three slots 11, respectively. The three first detection sensors 502 can detect whether the clips 2 are all assembled in the three slots 11.

[0053] (v) Material unloading station After inspection, the transfer mechanism 80 moves the connector body 1 one station to the unloading and handling mechanism 60. The unloading and handling mechanism 60 includes a second horizontal drive assembly 601, a second vertical drive assembly 602, and an unloading pneumatic gripper 603. Through the cooperation of the second horizontal drive assembly 601 and the second vertical drive assembly 602, the unloading pneumatic gripper 603 is driven to move, removing the inspected finished connector assembly from the transfer carrier 810, completing the unloading process. (Refer to...) Figure 15 The figure shows the changes in the state of the connector body 1 and the clamp 2 before and after assembly. After assembly, each clamp 2 is securely contained in the corresponding slot 11 and will not come out due to the rotation of the transfer carrier 810.

[0054] It should be noted that the horizontal and vertical drive components and other transfer structures are structures that should be well known to those skilled in the art, such as cylinder linear drive, multi-axis drive of robotic arms, motor drive belt linear drive, electric cylinder linear drive, etc.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
