Description

Technical Field

[0001] This application relates to the field of automated assembly equipment technology, and in particular to quick pipe fitting assembly equipment. 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 quick-connect body has several (e.g., three) clamps on its outer circumference, and the movable sleeve has several slots on its inner wall that mate with the sidewalls of the clamps. During assembly, the clamps are first inserted into the corresponding clamps on the outer circumference of the quick-connect body, and the spring is simultaneously inserted into the movable sleeve. Then, the quick-connect body with the clamps is inserted into the movable sleeve with the spring, so that the spring is fitted over the clamps, and the movable sleeve is completely fitted over the quick-connect body and can slide within a certain range. Sliding compresses the spring. Finally, the nut is attached to the quick-connect body, completing the assembly of the quick-connect fitting.

[0003] The aforementioned quick-connect fittings have a large number of parts, and there are a series of assembly steps requiring precise control, such as orientation identification (e.g., the slots and grooves must correspond one-to-one) and positioning checks (e.g., whether the spring is in place and whether the movable sleeve is facing the correct direction). Furthermore, since multiple clamps and grooves are assembled, care must be taken to ensure that the previous clamp does not dislodge from its corresponding groove when assembling the next clamp; otherwise, defective products will be produced. Currently, the mainstream assembly method for quick-connect fittings still relies heavily on manual operation. During the assembly process, steps such as aligning the parts, inserting them one by one, and checking positioning are all done manually by visual inspection. This results in low assembly efficiency, high labor intensity, and poor assembly consistency, directly affecting the product's pass rate and reliability, making it difficult to meet the needs of large-scale, automated production.

[0004] Therefore, how to provide an automated assembly equipment that can automatically complete the rapid assembly of multi-part, multi-process pipe joints and also take into account the assembly quality inspection is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] The purpose of this invention is to provide an automated assembly equipment for quick-connect pipe fittings, so as to solve the technical problems of low efficiency, high labor intensity and poor assembly consistency caused by manual assembly of quick-connect pipe fittings in the prior art, and realize the automated feeding, alignment, assembly, inspection and transfer of quick-connect fitting body, clamp, spring, movable sleeve and fitting nut.

[0006] The quick pipe fitting assembly equipment provided in this application adopts the following technical solution: A quick-connect fitting assembly device includes: a body and clamp assembly unit for assembling several clamps into several grooves on the outer periphery of the quick-connect fitting body to form a semi-finished component one; a spring feeding unit for supplying springs; a spring and movable sleeve assembly unit for feeding the movable sleeve; a first transfer mechanism disposed between the spring feeding unit and the spring and movable sleeve assembly unit for grabbing the springs supplied by the spring feeding unit and placing the springs into the inner side of the movable sleeves obtained by the spring and movable sleeve assembly unit to form a semi-finished component two; and a transfer device disposed between the body and clamp assembly unit and the spring and movable sleeve assembly unit for grabbing the springs supplied by the spring feeding unit. The body and the clamp assembly unit form a semi-finished component one, and the semi-finished component one is inserted into the inner side of the semi-finished component two; the spring and movable assembly unit is also used to press the inserted semi-finished component one into the inner side of the semi-finished component two to form a semi-finished component three; the connector nut assembly unit is used to feed the connector nut and assemble the connector nut onto the quick connector body of the semi-finished component three to obtain a quick pipe connector finished product; the second transfer mechanism is set between the spring and movable assembly unit and the connector nut assembly unit to transfer the semi-finished component three from the spring and movable assembly unit to the connector nut assembly unit.

[0007] By adopting the above technical solution, the four major units of body and clamp assembly, spring feeding, spring and movable sleeve assembly, and connector nut assembly are organically connected through transfer device, first transfer mechanism and second transfer mechanism. This realizes the fully automated assembly of five parts, including quick connector body, clamp, spring, movable sleeve and connector nut, from material feeding to finished product. It gets rid of the existing technology that relies on manual assembly, significantly improves assembly efficiency, reduces labor intensity, and ensures the continuity and consistency of each process at the whole machine level.

[0008] Optionally, the body and the card head assembly unit, the spring feeding unit and the spring and the movable set assembly unit operate synchronously to complete the assembly of the semi-finished component one and the formation of the semi-finished component two in parallel. Then, the transfer device transfers the semi-finished component one and inserts it into the inside of the semi-finished component two for assembly. By adopting the above technical solution, the body and the chuck assembly unit, the spring feeding unit, and the spring and movable set assembly unit operate synchronously and produce semi-finished component one and semi-finished component two in parallel. This avoids the waiting time waste caused by the completely serial assembly of the chuck and the spring, effectively shortens the production cycle of the whole machine, and improves the output efficiency per unit time.

[0009] Optionally, the body and clamp assembly unit includes a first turntable conveying mechanism, and a quick connector body feeding mechanism, several clamp feeding mechanisms, a switching mechanism, and a clamp assembly detection mechanism arranged around the outer edge of the first turntable conveying mechanism. The quick connector body feeding mechanism is used to feed the quick connector body and align the angles of several clamp slots on its outer periphery before placing it onto a first carrier on the first turntable conveying mechanism. Several clamp feeding mechanisms are arranged sequentially along the conveying path of the first turntable conveying mechanism to sequentially assemble clamps into the inner sides of different clamp slots on the outer periphery of the quick connector body. The switching mechanism is arranged between two adjacent clamp feeding mechanisms to drive the quick connector body to rotate by a preset angle to switch the clamp slot to be assembled. The clamp assembly detection mechanism is used to detect whether several clamps are assembled in place. By adopting the above technical solution, the loading and alignment of the quick connector body, the sequential assembly of multiple clamps, and the assembly quality inspection can be completed continuously on the same turntable station, reducing the number of material transfers and transfer errors between different stations, and improving the automation level and production stability of the clamp assembly process.

[0010] Optionally, the quick connector body feeding mechanism includes a quick connector vibration feeding assembly, a quick connector feeding and conveying assembly, and a first centrifugal alignment assembly arranged in sequence. The first centrifugal alignment assembly includes an alignment carrier, a centrifugal alignment rod rotatably disposed inside the alignment carrier, and a first rotary drive component that drives the alignment carrier to rotate. The first rotary drive component drives the alignment carrier to rotate, causing the centrifugal alignment rod to expand outward under centrifugal force and engage in the inner side of the slot, thereby rotating the quick connector body and aligning the angle position of several slots on the outer periphery of the quick connector body to a preset position. By adopting the above technical solution, the centrifugal straightening rod automatically expands and engages with the slot during rotation due to centrifugal force, driving it to rotate to a preset angle. This achieves automated, low-cost straightening of the slot angle position without visual recognition. Compared with methods that rely on visual positioning or manual straightening, this method has a simple structure, low cost, and high straightening efficiency, making it easier for the subsequent clamping head to be accurately aligned with the slot for assembly.

[0011] Optionally, the chuck loading mechanism includes a chuck vibration loading component and a chuck loading and conveying component. The chuck loading and conveying component includes a second rotary drive, a lifting drive, a second pneumatic gripper, and a chuck pushing assembly structure. The second rotary drive drives the lifting drive, the second pneumatic gripper, and the chuck pushing assembly structure to rotate by a preset angle, so that the lifting drive drives the second pneumatic gripper to descend and grab the chuck at the end of the chuck vibration loading component. Then, it rotates in the opposite direction by the preset angle to align the chuck with the chuck slot. After the lifting drive drives the second pneumatic gripper to move to the vicinity of the chuck slot, the chuck pushing assembly structure pushes the chuck into the corresponding chuck slot and presses out a limiting groove on the side wall of the chuck slot to form a radial limit on the chuck inside. A first positioning component is also provided at a position opposite to the chuck loading mechanism for clamping and positioning the quick connector body during the chuck assembly process. By adopting the above technical solution, on the one hand, the quick connector body is clamped by the first positioning component to prevent it from rotating during assembly, thus ensuring assembly accuracy; on the other hand, the chuck push assembly structure pushes the chuck into the slot while pressing out the limiting groove to form a radial limit on the chuck, eliminating the need for additional fixing processes or fixing parts. While realizing automated assembly, it directly improves the reliability of the chuck after assembly, prevents it from coming out of the slot later, greatly simplifies the process, and improves product quality.

[0012] Optionally, the spring feeding unit includes a second turntable conveyor mechanism, and an automatic spring feeding unit, a semi-automatic spring feeding unit, a spring detection mechanism, and a misaligned spring unloading mechanism arranged around the second turntable conveyor mechanism; the automatic spring feeding unit is used to automatically supply springs and transport them to a second carrier on the second turntable conveyor mechanism; the semi-automatic spring feeding unit is used to transport springs to the second carrier when the automatic spring feeding unit malfunctions, and the automatic spring feeding unit and the semi-automatic spring feeding unit do not operate simultaneously; the spring detection mechanism is used to detect whether the springs are placed in place, and misaligned springs that are not placed in place are removed by the misaligned spring unloading mechanism; the springs gripped by the first transfer mechanism come from the second carrier; By adopting the above technical solution, and by setting up two sets of feeding methods—an automatic spring feeding unit and a semi-automatic spring feeding unit—which serve as backups for each other and do not operate simultaneously, the equipment can continue to supply springs in a semi-automatic manner even when the automatic feeding component fails. This avoids the entire machine from shutting down due to a failure in a single feeding link, and significantly improves the continuity, reliability, and fault tolerance of the equipment operation.

[0013] Optionally, the spring detection mechanism includes a pressure detection cylinder and a detection sensor. The pressure detection cylinder presses down on the spring in the second carrier, and the detection sensor detects the descent distance at the output end of the pressure detection cylinder. When the descent distance is the same as a preset distance, it is determined that the spring is in place. When the descent distance is different from the preset distance, it is determined that the spring is misaligned. By adopting the above technical solution, the spring is determined to be in place by detecting whether the descent distance of the pressing detection cylinder is equal to the preset distance. The detection structure is simple, low-cost, and has a fast response speed. It can promptly remove misaligned springs, ensure the assembly quality of semi-finished component two, and avoid unqualified semi-finished products flowing into subsequent processes and causing waste.

[0014] Optionally, the spring and movable sleeve assembly unit includes a third turntable conveyor mechanism, and a movable sleeve vibrating feeding plate, a movable sleeve orientation detection component, a feeding and straightening component, a linear vibrating conveyor table, a movable sleeve feeding mechanism, a second centrifugal straightening component, and a spring assembly detection mechanism disposed on the outer periphery of the third turntable conveyor mechanism; the movable sleeve orientation detection component is used to detect the orientation of the movable sleeve at the output end of the movable sleeve vibrating feeding plate. When an incorrect orientation is detected, the feeding and straightening component flips the movable sleeve and then conveys it to the linear vibrating conveyor table; when a correct orientation is detected, the spring assembly is completed. The movable sleeve is directly conveyed to the vertical vibration conveyor table by the feeding and straightening assembly; the movable sleeve feeding mechanism is used to transport the movable sleeve on the vertical vibration conveyor table to the second centrifugal straightening assembly for straightening, and then place it on the third carrier on the third turntable conveyor mechanism; the first transfer mechanism places the spring inside the movable sleeve fed by the movable sleeve feeding mechanism to form the second semi-finished product assembly; the spring assembly and detection mechanism is used to press the first semi-finished product assembly after being inserted and placed by the transfer device into the inside of the second semi-finished product assembly to form the third semi-finished product assembly; By adopting the above technical solution, the combination of movable sleeve orientation detection and flipping and straightening solves the pain point of relying on manual visual correction in the existing technology, which is based on the uncertainty of the movable sleeve feeding direction, and improves the automation success rate and consistency of the overall assembly.

[0015] Optionally, the spring assembly detection mechanism includes a press-fit drive component and a press-fit completion detection sensor. The press-fit drive component is used to press the semi-finished component one into the inner side of the semi-finished component two. The press-fit completion detection sensor is used to detect the press-fit stroke of the press-fit drive component. When the press-fit stroke is the same as the preset stroke, it is determined that the press-fit is in place, forming a qualified semi-finished component three. When the press-fit stroke is different from the preset stroke, it is determined that the press-fit is not in place. By adopting the above technical solution, the spring assembly inspection mechanism can determine whether the pressing is in place by detecting the pressing stroke while completing the pressing action of semi-finished component one and semi-finished component two. There is no need to add an extra inspection station. The structure is simple and the inspection is timely, which avoids unqualified semi-finished products that are not pressed in place from flowing into subsequent processes.

[0016] Optionally, the second centrifugal alignment component has the same structure as the first centrifugal alignment component and is used to align the angular position of the slot inside the movable sleeve so that the angular position of the slot corresponds to the angular position of the slot on the outer periphery of the quick connector body. By adopting the above technical solution, since the second centrifugal alignment component and the first centrifugal alignment component adopt the same structure and alignment principle, on the one hand, the precise correspondence between the inner slot angle position of the movable sleeve and the quick connector body slot angle position is achieved, which ensures the smooth insertion and pressing of the semi-finished component one and the semi-finished component two; on the other hand, the two alignment mechanisms are universal in structure and can share the same design and parts, which reduces the design, development and maintenance costs of the equipment.

[0017] Optionally, the connector nut assembly unit includes a fourth turntable conveying mechanism, and a fourth carrier, a connector nut vibrating feeding plate, a nut feeding assembly mechanism, and a finished product unloading and conveying mechanism arranged around the fourth turntable conveying mechanism; the connector nut vibrating feeding plate is used to feed connector nuts; the nut feeding assembly mechanism is used to grab the connector nuts at the output end of the connector nut vibrating feeding plate and screw the connector nuts onto the quick connector body of the semi-finished component three on the fourth carrier to obtain the finished quick pipe connector; the finished product unloading and conveying mechanism is used to remove the finished quick pipe connector. By adopting the above technical solution, the feeding, tightening and assembly of the connector nuts and the unloading of the finished product are completed continuously on the same turntable station, which reduces the number of material transfers and improves the automation level and production cycle stability of the final assembly process.

[0018] Optionally, the nut feeding and assembly mechanism includes a third rotary drive and a third pneumatic gripper. The third pneumatic gripper is used to grab the connector nut at the output end of the connector nut vibrating feeding disc and transport it to the top of the semi-finished product assembly three. The third rotary drive is used to drive the third pneumatic gripper to rotate so as to screw the connector nut onto the outside of the quick connector body of the semi-finished product assembly three. By adopting the above technical solution, the automatic screwing assembly of the connector nut and the quick connector body threaded connection is realized through the gripping and handling of the third pneumatic gripper and the screwing action of the third rotary drive component. No manual tightening is required, which ensures the consistency of assembly torque and assembly quality.

[0019] Optionally, the transfer device includes a first handling component, a conveying component, and a second handling component. The conveying component includes a circulating conveyor and a plurality of transfer carriers disposed on the circulating conveyor. The first handling component is used to handle the semi-finished component one from the body and the clamp assembly unit and place it onto the transfer carrier on the circulating conveyor. The circulating conveyor is used to convey the transfer carrier carrying the semi-finished component one to the second handling component. The second handling component is used to remove the semi-finished component one from the transfer carrier and insert it into the inside of the semi-finished component two. The circulating conveyor is also used to convey the empty transfer carrier back to the first handling component to realize the recycling of the transfer carrier. By adopting the above technical solution, the first handling component, the circulating conveyor and the second handling component cooperate with each other to complete the transfer of the semi-finished component one from the body and the clamp assembly unit to the spring and the movable set assembly unit, and directly complete the assembly action of inserting the semi-finished component one into the inside of the semi-finished component two. The recycling of the transfer carrier further improves the transfer efficiency and reduces the space occupied by the equipment.

[0020] Optionally, the first transfer mechanism and / or the second transfer mechanism includes a horizontal drive, a lifting drive at the output end of the horizontal drive, and a pneumatic gripper at the output end of the lifting drive. The pneumatic gripper moves between a gripping position and a placing position under the drive of the horizontal drive and the lifting drive, so as to realize the gripping, transfer and placement of the corresponding material. By adopting the above technical solution, the horizontal drive component realizes the gripping, transfer and precise placement of corresponding materials between different workstations through a combination of horizontal displacement, lifting and lowering and gripper opening and closing actions. The structure is simple, the action is reliable, and it is easy to coordinate with the cycle of adjacent turntable workstations.

[0021] In summary, this application includes at least one of the following beneficial technical effects: This invention automates the entire process of quick connector assembly, from material feeding, alignment, assembly to inspection and transfer, by setting up four functional units: body and clamp assembly unit, spring feeding unit, spring and movable sleeve assembly unit, and connector nut assembly unit. These units are organically connected by a transfer device, a first transfer mechanism, and a second transfer mechanism. This eliminates the need for manual intervention in the main assembly processes, significantly improving the assembly efficiency of quick connectors and reducing labor intensity. The main body and the card head assembly unit of this invention operate synchronously with the spring and movable set assembly unit and the spring feeding unit, and independently complete the production of semi-finished component one and semi-finished component two, which are then assembled by the transfer device. Compared with serial processes, this can effectively shorten the production cycle of the whole machine and improve the overall production efficiency of the equipment. The spring feeding unit of this invention is equipped with two sets of feeding methods: an automatic spring feeding unit and a semi-automatic spring feeding unit, which are backups to each other and do not work simultaneously. When the automatic feeding unit fails, the semi-automatic feeding unit can promptly supplement the feeding, avoiding the shutdown of the entire machine due to the failure of a single feeding method, and improving the continuity and reliability of equipment operation. The combination of the movable sleeve orientation detection component and the feeding and aligning component in this invention can automatically identify and correct the feeding orientation of the movable sleeve, avoiding subsequent assembly failures due to incorrect movable sleeve orientation and improving the success rate of automated assembly.

[0022] The spring assembly and inspection mechanism, while completing the pressing action of semi-finished component one and semi-finished component two, determines whether the pressing is in place by detecting the pressing stroke. It has both assembly and inspection functions, and is compact in structure and timely in inspection. Attached Figure Description

[0044] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0045] It should be noted that the basic structure of the quick-connect pipe fitting 10 used for assembly in this invention belongs to the prior art, such as... Figure 1 , Figure 2 As shown, it includes a quick connector body 11, a locking head 12, a spring 14, a movable sleeve 13, and a connector nut 15. The quick connector body 11 has several locking grooves 111 on its outer periphery. In this application, the locking grooves 111 are preferably three. The inner wall of the movable sleeve 13 has slots 131 that are adapted to the locking grooves 111. The movable sleeve 13 has several actuating grooves 16 on its outer periphery.

[0046] like Figure 3 and Figure 4 As shown, the quick pipe fitting assembly equipment provided by the present invention includes a body and clamp assembly unit 100, a spring feeding unit 200, a spring and movable sleeve assembly unit 300, a fitting nut assembly unit 400, a transfer device 500, a first transfer mechanism 600, and a second transfer mechanism 700.

[0047] The quick connector body and clamp assembly unit 100 is used to load and assemble the quick connector body 11 and clamps 12, respectively assembling the three clamps 12 into the three slots 111 on the outer periphery of the quick connector body 11 to form a semi-finished component one; the spring feeding unit 200 is used to load the spring 14; the spring and movable sleeve assembly unit 300 is used to load the movable sleeve 13; a transfer device 500 is provided between the body and clamp assembly unit 100 and the spring and movable sleeve assembly unit 300, which is used to grab and transfer the semi-finished component one from the body and clamp assembly unit 100 and insert it into the inner side of the semi-finished component two; a first transfer mechanism is provided between the spring feeding unit 200 and the spring and movable sleeve assembly unit 300. 600, the first transfer mechanism 600 is used to grab and transfer the spring 14 from the spring feeding unit 200 and place it inside the movable sleeve 13 obtained by the spring and movable sleeve assembly unit 300 to form the second semi-finished component; then the spring and movable sleeve assembly unit 300 presses the first semi-finished component after the transfer device 500 is inserted into the inside of the second semi-finished component to form the third semi-finished component; a second transfer mechanism 700 is set between the spring and movable sleeve assembly unit 300 and the connector nut assembly unit 400 to transport the third semi-finished component to the connector nut assembly unit 400, and then the connector nut assembly unit 400 feeds the connector nut 15 and assembles the connector nut 15 onto the third semi-finished component to obtain the finished quick pipe connector 10.

[0048] It should be noted that the body and the clamp assembly unit 100, the spring feeding unit 200 and the spring and movable sleeve assembly unit 300 operate synchronously. That is, the assembly of semi-finished component one and the feeding of movable sleeve 13 and the formation of semi-finished component two are carried out in parallel. Finally, semi-finished component one is inserted into the inside of semi-finished component two by the transfer device 500 and is pressed and joined at the spring and movable sleeve assembly unit 300, thereby improving the production cycle of the whole machine.

[0049] like Figure 5 and Figure 6 As shown, the body and card head assembly unit 100 is set on the first workbench 110, including a quick connector body feeding mechanism 130, three card head feeding mechanisms 140, a card head assembly detection mechanism 160, a first positioning component 1430 and a shifting mechanism 150 arranged around the outer edge of the first turntable conveying mechanism 120. The first positioning component 1430 is arranged at a position opposite to the card head feeding mechanism 140, and the shifting mechanism 150 is arranged between two adjacent card head feeding mechanisms 140.

[0050] The quick connector body feeding mechanism 130 includes a quick connector vibration feeding assembly 1310, a quick connector feeding and conveying assembly 1320, and a first centrifugal alignment assembly 1330 arranged sequentially. The quick connector vibration feeding assembly 1310 vibrates and feeds the quick connector body 11. The quick connector feeding and conveying assembly 1320 is equipped with two first pneumatic grippers 13201, which cooperate with the first centrifugal alignment assembly 1330 to transport the quick connector body 11 at the end of the quick connector vibration feeding assembly 1310 onto the alignment carrier 13301 on the first centrifugal alignment assembly 1330. At this time, the angular positions of the three outer peripheral slots 111 are uncertain. Figure 7As shown, the first centrifugal alignment assembly 1330 also includes centrifugal alignment rods 13302 and a first rotary drive 13303. The centrifugal alignment rods 13302 are rotatably disposed inside the alignment carrier 13301. When the quick connector body 11 is sleeved on the alignment carrier 13301, it is simultaneously sleeved on the outer side of the ends of several centrifugal alignment rods 13302. The first rotary drive 13303 drives the alignment carrier 13301 to rotate. During the rotation, since the quick connector body 11 is initially placed on the outer side of the alignment carrier 13301, the two are not completely fixed or snapped together. Therefore, the initial rotation speed of the alignment carrier 13301 will be greater than that of the quick connector. The rotational speed of the head body 11 causes the alignment carrier 13301 to rotate relative to the quick connector body 11. Subsequently, due to centrifugal force, the end of the centrifugal alignment rod 13302 located inside the quick connector body 11 expands outward and engages with the inside of the slot 111. At this time, the alignment carrier 13301 and the quick connector body 11 rotate synchronously. The first rotary drive 13303 drives the alignment carrier 13301 to rotate for a preset time, number of revolutions, or angle each time and then stops, so that the centrifugal alignment rod 13302 stops at a preset angle position each time. At this time, the three slots 111 also stop at the preset position, thus completing the automatic alignment of the quick connector body 11. Subsequently, the quick connector loading and conveying assembly 1320 transports the aligned quick connector body 11 to the first carrier 1210 on the first turntable conveying mechanism 120.

[0051] The first turntable conveyor mechanism 120 drives the quick connector body 11 to rotate one station, moving it to the position of the first clamping head feeding mechanism 140. At this position, the first positioning component 1430 clamps the quick connector body 11, positioning it and preventing it from rotating. Subsequently, the clamping head feeding mechanism 140 transports and assembles the clamping head 12 into the corresponding clamping slot 111.

[0052] like Figure 8As shown, the card head feeding mechanism 140 includes a card head vibration feeding assembly 1410 and a card head feeding and conveying assembly 1420. The card head feeding and conveying assembly 1420 includes a second rotary drive 14201, a lifting drive 14202, a second pneumatic gripper 14203, and a card head pushing assembly structure 14204. The specific assembly process is as follows: the second rotary drive 14201 drives the lifting drive 14202, the second pneumatic gripper 14203 and the chuck push assembly structure 14204 to rotate by a preset angle (e.g., 90 degrees), so that the second pneumatic gripper 14203 grabs the chuck head 12 at the end of the chuck head vibration feeding assembly 1410, and then rotates in the opposite direction by a preset angle so that the chuck head 12 is aligned with the position of the chuck slot 111. Subsequently, the lifting drive 14202 transports the second pneumatic gripper 14203 to the vicinity of the corresponding chuck slot 111. Then, the chuck head 12 is pushed into the inside of the chuck slot 111 by the chuck head push assembly structure 14204, and a limiting groove is pressed out on the side wall of the chuck slot 111 to form a radial limit on the chuck head 12 inside it. For example, a protruding extrusion rib is integrally provided at the pushing end of the card head pushing assembly structure 14204. When the card head pushing assembly structure 14204 pushes the card head 12 into the card slot 111, the extrusion rib presses against the side wall of the card slot 111 opposite to the card head pushing assembly structure 14204. As the card head pushing assembly structure 14204 pushes into place, the extrusion rib presses out a tiny limiting groove on the side wall. The edge of the limiting groove protrudes slightly into the inside of the card slot 111, thereby forming a radial limit on the card head 12 inside the card slot 111 and preventing it from subsequently coming out of the card slot 111.

[0053] After the first clamp head 12 is assembled, the first turntable conveyor 120 drives the quick connector body 11, which is equipped with the first clamp head 12, to rotate one station to reach the switching mechanism 150. The switching mechanism 150 drives the quick connector body 11 to rotate by a preset angle (e.g., 120 degrees) so that the second empty clamp slot 111 faces the next assembly position. Then, the first turntable conveyor 120 drives the quick connector body 11 to rotate one station to reach the position of the second clamp head feeding mechanism 140 to assemble the second clamp head 12. This cycle is repeated to complete the assembly of the third clamp head 12. After the three clamp heads 12 are assembled, a semi-finished component is formed.

[0054] The first turntable conveyor 120 drives the semi-finished component 1 to the clamp head assembly and inspection mechanism 160. The clamp head assembly and inspection mechanism 160 checks whether the clamp heads 12 are installed in place from three directions corresponding to the three clamp heads 12. After the inspection is completed, the first turntable conveyor 120 transports the semi-finished component 1 to the transfer device 500, which picks up and transfers it to the spring and movable set assembly unit 300. The semi-finished component 1 that is not installed in place can be removed by other unloading mechanisms or manually.

[0055] like Figure 9As shown, the transfer device 500 includes a first handling component 510, a conveying component 520, and a second handling component 530. The conveying component 520 includes a circulating conveyor 5201 and multiple transfer carriers 5202 disposed on the circulating conveyor 5201. The first handling component 510 transports semi-finished component one from the body and the clamp assembly unit 100 to the transfer carriers 5202 on the circulating conveyor 5201. The circulating conveyor 5201 then transports the transfer carriers 5202 carrying semi-finished component one to the second handling component 530, whereby the second handling component 530 removes semi-finished component one from the transfer carriers 5202 and inserts it into the inner side of semi-finished component two. Simultaneously, the circulating conveyor 5201 transports the empty transfer carriers 5202 back to the first handling component 510, thereby realizing the recycling of the transfer carriers 5202 and improving the transfer efficiency. It should be noted that the first conveying component 510 and the second conveying component 530 can both adopt the same combination structure of horizontal drive component, lifting drive component and pneumatic gripper as the first transfer mechanism 600 and the second transfer mechanism 700 described later to realize the gripping and placement of materials, which will not be elaborated further.

[0056] like Figures 10 to 12 As shown, the spring feeding unit 200 is disposed on the second workbench 210 and includes a second turntable conveying mechanism 220, an automatic spring feeding unit 230, a semi-automatic spring feeding unit 240, a spring detection mechanism 250, and a misaligned spring unloading mechanism 260 arranged around the second turntable conveying mechanism 220.

[0057] The automatic spring feeding unit 230 includes an automatic spring feeding mechanism 2310 and a first spring conveying assembly 2320. In an optional embodiment, the automatic spring feeding mechanism 2310 is a spring vibration feeding device. The first spring conveying assembly 2320 is used to transport the processed springs 14 onto the second carrier 2210 on the second turntable conveyor mechanism 220. Subsequently, the second turntable conveyor mechanism 220 drives the second carrier 2210 to rotate one station to the position of the semi-automatic spring feeding unit 240.

[0058] It should be noted that when the automatic spring feeding unit 230 is working normally, the semi-automatic spring feeding unit 240 does not participate in the assembly; the significance of the semi-automatic spring feeding unit 240 is that when the automatic spring feeding unit 230 malfunctions and cannot work normally, the semi-automatic spring feeding unit 240 can complete the semi-automatic feeding of the spring 14. The automatic spring feeding unit 230 and the semi-automatic spring feeding unit 240 do not work at the same time.

[0059] like Figure 13As shown, the semi-automatic spring feeding unit 240 includes a manual spring feeding mechanism 2410 and a second spring conveying assembly 2420. The manual spring feeding mechanism 2410 includes several preparation rods 24101 mounted in a circumferential matrix on a rotatable drive structure. The operator places several springs 14 onto the preparation rods 24101. During semi-automatic feeding, the spring lifting assembly 24102 pushes all the springs 14 on the opposite preparation rods 24101 from the bottom, causing them to gradually move upwards by one spring 14 at a time. The second spring conveying assembly 2420 grabs the spring 14 located at the top and places it on the spring preparation rack 24103, while simultaneously conveying the spring 14 originally located on the spring preparation rack 24103 to the corresponding second carrier 2210, thereby completing the semi-automatic feeding.

[0060] Subsequently, the second turntable conveyor 220 rotates the second carrier 2210, which carries the spring 14, one station to the position of the spring detection mechanism 250. The spring detection mechanism 250 includes a pressure detection cylinder 2501 and a detection sensor 2502. The pressure detection cylinder 2501 presses down to detect whether the spring 14 is placed in the correct position on the second carrier 2210. The correct position is when the spring 14 is placed at the bottom inner side of the second carrier 2210, with the top of the spring 14 approximately flush with the top of the second carrier 2210. If the spring 14 is defective during production, or if it is misplaced when placed inside the second carrier 2210, its top will be higher than the top of the second carrier 2210 and tilted. In this case, when the pressure detection cylinder 2501 presses down, the spring 14 is prone to interference with the top of the second carrier 2210, preventing the pressure detection cylinder 2501 from descending to the height corresponding to the correct position of the spring 14; that is, its descent distance differs from the preset distance when the spring 14 is correctly placed. The descent distance of the pressure detection cylinder 2501 is detected by the detection sensor 2502. When the descent distance is the same as the preset distance, it is determined that the spring 14 is correctly placed; otherwise, it is determined that the spring is misplaced.

[0061] After the judgment is completed, the second turntable conveyor 220 drives the spring 14 to move forward one station to one end of the first transfer mechanism 600. The first transfer mechanism 600 grabs the spring 14 from the second carrier 2210 and transfers it. If it is determined to be a misaligned spring, the second turntable conveyor 220 moves forward two stations to the misaligned spring unloading mechanism 260, and removes it through the misaligned spring unloading mechanism 260.

[0062] like Figures 14 to 16As shown, the spring and movable sleeve assembly unit 300 is located on one side of the second workbench 210, including a third turntable conveyor mechanism 310, a third carrier 320, a movable sleeve vibrating feeding plate 330, a movable sleeve orientation detection component 340, a linear vibration conveyor 370, a feeding and aligning component 350, a movable sleeve feeding mechanism 360, a second centrifugal aligning component 3610, and a spring assembly detection mechanism 380 arranged around the third turntable conveyor mechanism 310.

[0063] The vibrating feeder 330 vibrates and feeds the movable sleeve 13. The movable sleeve 13 at its end is located at the movable sleeve orientation detection component 340. The movable sleeve orientation detection component 340 detects the distance from the movable sleeve 13 to the movable sleeve orientation detection component 340 from multiple directions: when the head of the movable sleeve 13 is facing upward, that is, when the actuating groove 16 on its outer periphery is below the output end of the movable sleeve orientation detection component 340, it is judged that the orientation is normal and does not need to be flipped; otherwise, it is judged that it needs to be flipped.

[0064] When flipping is required, the feeding and aligning assembly 350 transports the movable sleeve 13, which faces the detection assembly 340, onto the vertical vibration conveyor 370. During the transport process, the flipping assembly 3501 on the feeding and aligning assembly 350 flips the movable sleeve 13 vertically to ensure that all movable sleeves 13 on the vertical vibration conveyor 370 are in an upward-facing state. When flipping is not required, the feeding and aligning assembly 350 directly transports the movable sleeve 13, which faces the detection assembly 340, onto the vertical vibration conveyor 370. Subsequently, the vertical vibration conveyor 370 transports the movable sleeve 13 to its end, and the movable sleeve feeding mechanism 360 transports the movable sleeve 13 at the end of the vertical vibration conveyor 370 onto the second centrifugal aligning assembly 3610. At the same time, the movable sleeve 13 originally on the second centrifugal aligning assembly 3610 is transported onto the third carrier 320, completing the feeding of the movable sleeve 13. The second centrifugal alignment component 3610 has the same structure as the first centrifugal alignment component 1330. It is used to align the position of the slot 131 inside the movable sleeve 13 so that it corresponds to the position of the slot 111 on the outer periphery of the quick connector body 11, which facilitates subsequent insertion.

[0065] After the movable sleeve 13 is loaded, the third turntable conveyor 310 rotates it one station to one end of the first transfer mechanism 600. At this time, the first transfer mechanism 600 places the spring 14, which is gripped from the second carrier 2210 of the spring feeding unit 200, into the inside of the movable sleeve 13, forming the second semi-finished component. Then, the third turntable conveyor 310 moves the second semi-finished component into the second handling component 530 of the transfer device 500. The second handling component 530 removes the first semi-finished component from the transfer carrier 5202 and places it into the inside of the second semi-finished component. Subsequently, the third turntable conveyor 310 drives the semi-finished component two, after insertion, to move one station to the spring assembly and inspection mechanism 380. The spring assembly and inspection mechanism 380 includes a pressing drive 3801 and a pressing position detection sensor 3802. The pressing drive 3801 presses the semi-finished component one into the inner side of the semi-finished component two, so that the spring 14 inside the semi-finished component two is fitted onto the outer side of the three clips 12, and the side wall of the slot 111 on the outer periphery of the quick connector body 11 is inserted into the inner side of the slot 131 inside the movable sleeve 13, and the movable sleeve 13 is completely fitted onto the outer side of the quick connector body 11, forming the semi-finished component three. The pressing position detection sensor 3802 synchronously detects the pressing stroke of the pressing drive 3801. When the pressing stroke is the same as the preset stroke, it is determined that the pressing is in place, forming a qualified semi-finished component three. When the pressing stroke is different from the preset stroke, it is determined that the pressing is not in place. The unqualified semi-finished component three can be removed manually or by a specially set unloading mechanism. Afterwards, the third turntable conveyor 310 drives the qualified semi-finished components to move one station to one end of the second transfer mechanism 700 for standby.

[0066] like Figures 17 to 19 As shown, the connector nut assembly unit 400 is located on one side of the second workbench 210 and includes a fourth turntable conveyor mechanism 410, a fourth carrier 4110, a connector nut vibrating feeding plate 420, a nut feeding assembly mechanism 430, and a finished product unloading and conveying mechanism 440 arranged around the fourth turntable conveyor mechanism 410.

[0067] The second transfer mechanism 700 transports the semi-finished component three and places it onto the fourth carrier 4110 on the fourth turntable conveyor 410. Then, the fourth turntable conveyor 410 rotates the semi-finished component three one station to the nut loading and assembly mechanism 430. The joint nut vibrating loading plate 420 vibrates and loads the joint nut 15. For example... Figure 20As shown, the nut loading and assembly mechanism 430 includes a third rotary drive 4310 and a third pneumatic gripper 4320. The third pneumatic gripper 4320 picks up the connector nut 15 from the output end of the connector nut vibrating loading plate 420 and transports it above the semi-finished product assembly three. The third rotary drive 4310 drives the third pneumatic gripper 4320 to rotate, so as to rotate and screw the connector nut 15 onto the top outer side of the quick connector body 11 of the semi-finished product assembly three, completing the assembly and obtaining the quick connector 10 finished product. After the assembly is completed, the quick connector 10 finished product is removed by the finished product unloading and conveying mechanism 440.

[0068] It should be noted that the first transfer mechanism 600 and the second transfer mechanism 700 can both be implemented using the same gripping and transfer structure. For example, both include a horizontal drive component, a lifting drive component located at the output end of the horizontal drive component, and a pneumatic gripper located at the output end of the lifting drive component. The pneumatic gripper moves between the gripping position and the placement position under the drive of the horizontal drive component and the lifting drive component to realize the gripping, transfer and placement of the corresponding material. The horizontal drive component drives the lifting drive component to move above the gripping position. The lifting drive component drives the pneumatic gripper to descend and grips the corresponding material (spring 14 or semi-finished component three) through the pneumatic gripper. Then, the lifting drive component drives the pneumatic gripper to rise. The horizontal drive component drives the lifting drive component to move in the opposite direction to above the placement position. The lifting drive component drives the pneumatic gripper to descend again, placing the material in the corresponding workstation (inside the movable sleeve 13 or the fourth carrier 4110) and then releasing the pneumatic gripper to complete one gripping, transfer and placement action. The gripping, transporting and placing structures of the first transport component 510 and the second transport component 530 are the same as those of the first transport mechanism 600 and the second transport mechanism 700 mentioned above. They realize the transporting and insertion of the semi-finished component one through a combination of horizontal displacement, lifting and lowering and gripping actions.

[0069] It should be noted that the number of slots 111 and slots 12 in the body and slot assembly unit 100 is not limited to three. They can be set to two, four or more depending on the actual structure of the quick connector body 11. Correspondingly, the number of slot feeding mechanism 140, first positioning component 1430 and shifting mechanism 150 and the angle at which the shifting mechanism 150 drives the quick connector body 11 to rotate each time can also be adjusted accordingly. The switching between the spring automatic feeding unit 230 and the spring semi-automatic feeding unit 240 can be automatically judged and triggered by the control system according to the operating status of the spring automatic feeding mechanism 2310, or it can be triggered by manual intervention. The specific handling methods of the transfer device 500, the first transfer mechanism 600 and the second transfer mechanism 700 (such as cylinder linear handling, multi-axis handling by robotic arm, etc.) can be flexibly selected according to the actual production rhythm and factory layout.

[0070] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention should be included in the scope of the present invention.
