Description

Technical Field

[0001] The invention belongs to the field of electrical component assembly, and in particular relates to a suction-type quick assembly device and an assembly method for a double-female connector. Background Art

[0002] In the context of information warfare, the integrated layers and signal transmission components in electronic equipment are becoming increasingly miniaturized and highly integrated, and the requirements for structural assembly in small and compact spaces are becoming increasingly higher. Among them, the double-female connector used to connect core components such as antennas, active sub-arrays, and T / R components is an important medium for airborne and missile-borne radar signal transmission. It is also developing in the direction of small size, large quantity, high density, and high installation accuracy. Its assembly quality is related to the signal transmission reliability and stability in the RF circuit, which in turn affects the detection performance of the radar.

[0003] The double-female connector is tiny in size, with an outer diameter of 2 mm at the minimum. The mating surface adopts a petal opening elastic structure. When plugging and unplugging the double-female connector, appropriate axial force must be applied, which adds a certain degree of difficulty to the clamping of the double-female connector. After installation, the connection must be reliable, and the insulation between the inner core and the outer shell must meet the requirements. Especially when blind plugging occurs, the double-female petals may be damaged if not done carefully. In addition, before assembly, it is necessary to check that both end surfaces are intact, which is a lot of work. The assembly surface (such as a printed circuit board) that is plugged into the double-female connector is tightly arranged, so certain tools must be used for batch installation.

[0004] The more reliable way is to use the mechanical installation tool that comes with the connector for manual installation, but there are still some shortcomings:

[0005] (1) The gold-plated double-female connector cannot be touched with bare hands. Manual installation requires one hand wearing a glove to grab the double-female connector, and the other hand to press the spring cover. Then put one end of the double-female connector into the mechanical clamp of the matching tool to lock it, and then use the tool to install the double-female connector into the installation surface, and finally remove the tool.

[0006] (2) The double-female connector is very small in size and is very difficult to grasp with gloves on. It will often fall off, affecting installation efficiency.

[0007] (3) If the opening of the jaws of the matching tool is too large, the double-female connector will not be able to be clamped. If the opening is too small, the end face of the double-female connector will be damaged. Only an intermediate value can be used, and a certain amount of force must be applied to clamp it. For a fully escaped base, the separation force after docking is large. After installation, the removal of the tool will cause a small amount of double-female petals to deform, increasing costs. For a non-escaped base, the double-female connector will be pulled out together with the tool when the tool is removed, resulting in multiple installations, affecting installation efficiency.

[0008] (4) When the double-female connector is inserted into the mating surface below, it is difficult for the supporting tool to ensure the perpendicularity during assembly. If the insertion is skewed, there is a risk of damaging the docking points on the assembly surface, rendering the entire assembly surface scrapped and causing economic losses.

[0009] (5) There are dimensional differences at both ends of some double-female connectors, and it is easy to confuse the directions during installation. When problems are discovered later, it causes a large area of rework, and the process of direction identification is also time-consuming and laborious.

[0010] In summary, due to the large number of double-female connectors, operators need to repeatedly check, pick up multiple times, and carefully press and assemble. Therefore, there are problems such as high labor intensity, very low work efficiency, and frequent quality problems. Summary of the Invention

[0011] To overcome the deficiencies in the prior art, the present invention proposes a suction-type rapid assembly device and assembly method for double-female connectors, which effectively solve the problems of low end-face inspection efficiency, slow feeding speed, risk of damage during installation, high installation labor intensity and low efficiency, etc. during the assembly process of double-female connectors, avoid the problem of interference between the assembly tool and the surrounding double-female connectors in the compact structure design and blind installation scenarios, ensure the perpendicular insertion of the double-female connector and the mating surface below, and make the operation more convenient.

[0012] A suction-type rapid assembly device for double-female connectors proposed by the present invention includes a double-female rapid shaping device and a semi-automatic pneumatic assembly device; the double-female rapid shaping device includes a screen-type shaping device for double-female connectors with symmetric ends and no need to distinguish the mating surface, and a funnel-type shaping device for double-female connectors with asymmetric ends and need to distinguish the mating surface.

[0013] The screen-type shaping device includes a round-hole vibrating disk, a leak-proof cover plate and a double-female mirror disk; there are several double-female shaping holes arranged in an annular array in the round-hole vibrating disk; the leak-proof cover plate is covered on the round-hole vibrating disk; the double-female mirror disk is clamped on the round-hole vibrating disk, and several mirror shaping holes corresponding to the double-female shaping holes are arranged on the double-female mirror disk.

[0014] The funnel-type shaping device includes a long double-female dovetail-type guide rail base and a long double-female receiving drawer; a wedge-shaped feeding groove is arranged on the long double-female dovetail-type guide rail base; a vibrating notch for shaping and arranging double-female connectors is opened at the bottom of the wedge-shaped feeding groove; the long double-female receiving drawer is slidably arranged in the long double-female dovetail-type guide rail base, directly below the vibrating notch, and is used for receiving the double-female connectors after shaping and arranging.

[0015] The semi-automatic pneumatic assembly device is used to suck and assemble the double-female connector after shaping by the double-female quick shaping device, and includes a double-female matching head, a hollow mounting rod, a handle, a mounting rod adapter and an adjustable air supply device; one end of the double-female matching head is provided with a docking head adapted to the docking interface of the double-female connector for sucking the double-female connector; the hollow mounting rod is connected to the other end of the double-female matching head; the handle is mounted on the hollow mounting rod for easy grasping by the user; the mounting rod adapter is connected to the handle for externally connecting the adjustable air supply device.

[0016] The adjustable air supply device includes a lightweight air pipe, a micro air pump and an adjustable power supply; the lightweight air pipe is connected to the mounting rod adapter for guiding air and providing a moving distance for the double-female matching head; the micro air pump is connected to the lightweight air pipe for supplying air; the adjustable power supply is electrically connected to the micro air pump for controlling and adjusting the rotation speed of the micro air pump, thereby controlling the suction force on the double-female connector.

[0017] The spacing of the vibration notches is smaller than the diameter of the outer flange of the double-female connector, and the center of gravity offset and flange surface of the double-female connector's own structure are used to achieve positioning when shaking the long double-female dovetail guide base.

[0018] The assembly method of the sucking-type quick assembly device based on the double-female connector proposed by the present invention includes the following steps:

[0019] 1) Assemble the double-female matching head, the hollow mounting rod, the handle, the mounting rod adapter, the lightweight air pipe, the micro air pump and the adjustable power supply, and turn on the power; clean the wedge-shaped feeding groove, the vibration notches and the double-female matching head.

[0020] 2) Vibrationally shape a predetermined number of double-female connectors through the double-female quick shaping device, and check the end face of the double-female connectors.

[0021] 3) Turn on the adjustable power supply and adjust the suction force. Align the end face of the double-female matching head with the end of the double-female connector, and vertically suck it up to ensure that the flange surface of the double-female connector is aligned with the double-female matching head, without skew, and the suction is firm.

[0022] 4) Align the end of the sucked double-female connector with the printed board surface interface, insert the double-female connector, and after it is stable, remove the handle to complete the installation of the double-female connector.

[0023] If the double-female connector to be assembled is symmetric at both ends and there is no need to distinguish the mating surface, first select a round-hole vibrating disk that is compatible with the size of the double-female connector, as well as a leak-proof cover plate and a double-female mirror disk that are compatible with the size of the round-hole vibrating disk; pour a predetermined number of double-female connectors into the round-hole vibrating disk, cover the leak-proof cover plate on the round-hole vibrating disk, and shake it back and forth several times; open the leak-proof cover plate, and use a semi-automatic pneumatic assembly device to place the unshaped double-female connector into the double-female shaping hole; check the end face of the double-female connectors in the round-hole vibrating disk. If the end face is intact, proceed to the next step; if the end face is damaged, first use a semi-automatic pneumatic assembly device to remove the double-female connector with a damaged end face, and then proceed to the next step; cover the double-female mirror disk on the round-hole vibrating disk and turn it over so that the double-female mirror disk is placed below the round-hole vibrating disk. Open the round-hole vibrating disk and check the other end face of the double-female connectors in the double-female mirror disk. If the end face is intact, proceed to the next step. If the end face is damaged, first use a semi-automatic pneumatic double-female assembly device to remove the double-female connector with a damaged end face, and then proceed to the next step.

[0024] If the double-female connector to be assembled is asymmetric at both ends and the mating surface needs to be distinguished, first select a wedge-shaped feeding groove and a vibrating slot that are compatible with the size of the double-female connector; pour a predetermined number of double-female connectors onto the wedge-shaped feeding groove and slide them along the side wall of the wedge-shaped feeding groove to above the vibrating slot; shake the long double-female dovetail guide rail base back and forth along the long side direction of the vibrating slot until the double-females are uniformly arranged vertically along the long side of the vibrating slot; push the arranged double-female connectors to one side of the vibrating slot, continue to pour a predetermined number of double-female connectors onto the wedge-shaped feeding groove, and repeat the above operation until the vibrating slot is full; check the end face of the double-female connectors. If the end face is intact, proceed to the next step. If the end face is damaged, first use a semi-automatic pneumatic assembly device to remove the double-female connector with a damaged end face, and then proceed to the next step.

[0025] The round-hole vibrating disk can select a disk body with a compatible diameter according to the one-time assembly quantity, and the vibrating slot can select a compatible slot length according to the one-time operation quantity.

[0026] The beneficial effects of the present invention are as follows

[0027] (1) According to the guiding angle, aperture, hole depth and other parameters of the round-hole vibrating disk and the vibrating slot, the optimal size is determined. Only slight shaking is needed to shape the double-female connector, solving the problem of slow batch feeding, avoiding irregular scattering during incoming materials, and saving the time for batch inspection of the installation surface of the double-female connector.

[0028] (2) Solve the problems of difficult picking and easy dropping of double-female connectors, and save the picking time of double-female connectors.

[0029] (3) The clamping method using a hollow mounting rod and a double-female connector matching head combination, along with the negative pressure suction method, is adopted instead of the clamping method for installation, ensuring that the double-female connector is stably picked up vertically, which helps to ensure a vertical posture during mating insertion, avoid damage to the petals and the lower mounting surface caused by posture deviation during mating insertion, and save the product scrapping cost and rework cost.

[0030] (4) A semi-automatic pneumatic assembly device is adopted, which avoids the situation that the double-female connector is taken away due to excessive clamping force when the tool is withdrawn at the end of assembly, saving the time cost of repeated installation.

[0031] (5) The matching head is small in volume, and its diameter is basically the same as the size of the double-female connector. It will not interfere with the surrounding structural parts during assembly, and can complete the plugging and unplugging operations of the double-female connector within components with a compact space layout and in blind insertion scenarios.

[0032] (6) The original two-handed operation is optimized to one-handed operation, greatly reducing the labor intensity and workload, improving the installation quality, avoiding the situation where the quality is difficult to control due to manual operation, and at the same time avoiding hand contact with the double-female connector.

[0033] (7) It realizes convenient counting and standardized operation of the double-female connector, avoiding the assembly inconsistency caused by the change of the spring of the clamping tool due to individual strength variation.

[0034] (8) It can meet the assembly operations of double-female connectors with small dimensions, as well as installations at various special angles and in narrow spaces, effectively making up for the deficiencies of mechanical equipment and conventional tool use, and having a wide applicability.

Specific implementation mode

[0043] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0044] As Figures 1 - 4 shown, the sucking-type rapid assembly device for double female connectors includes a double female connector rapid shaping device and a semi-automatic pneumatic assembly device. The double female connector rapid shaping device includes a screen-type shaping device for rapidly shaping double female connectors with symmetric ends and indistinguishable mating surfaces, as Figure 1 shown, and a funnel-type shaping device for rapidly shaping double female connectors with asymmetric ends and distinguishable mating surfaces, as Figure 2 shown.

[0045] The screen-type shaping device includes a round hole vibrating disk 1, an anti-leakage cover plate 2 and a double female mirror disk 3. Specifically, a number of double female shaping holes are arranged in the round hole vibrating disk 1 in an annular array. The anti-leakage cover plate 2 is covered on the round hole vibrating disk 1 and is used to cooperate with the round hole vibrating disk 1 to arrange the double female connectors by vibration shaping. The double female mirror disk 3 is clamped on the round hole vibrating disk 1, and a number of mirror shaping holes corresponding to the double female shaping holes are arranged on the double female mirror disk 3 for flipping the double female to check the other end face.

[0046] The funnel-type shaping device includes a long double female dovetail guide rail base 4 and a long double female storage drawer 7. Specifically, a wedge-shaped feeding groove 5 for the double female connector to slide is arranged on the long double female dovetail guide rail base 4. A vibrating notch 6 for shaping and arranging the double female connector is opened at the bottom of the wedge-shaped feeding groove 5. The long double female storage drawer 7 is slidably arranged in the long double female dovetail guide rail base 4 and is located directly below the vibrating notch 6 for storing the shaped and arranged double females.

[0047] In actual use, a quick shaping device is provided to automatically and uniformly vertically arrange double-female connectors to meet the quick shaping requirements of double-females of different sizes. For double-female connectors with symmetric ends and indistinguishable mating surfaces, a screen-type shaping device is provided with a round-hole vibrating disk 1 adapted to the size of the double-female. A certain number of double-female connectors are poured into the round-hole vibrating disk 1, and a leak-proof cover plate 2 is covered. The vibration generated by repeated shaking causes the double-female connectors to automatically fall into the double-female shaping holes in the round-hole vibrating disk 1, so that the double-female connectors are finally uniformly and vertically arranged. At the same time, a double-female mirror disk 3 is provided, which can introduce the double-female connectors that have been shaped and inspected into the double-female mirror disk 3 to realize the inspection of the other end face of the double-female. For double-female connectors with asymmetric ends and distinguishable mating surfaces, a funnel-type shaping device is designed with a long double-female dovetail rail base body 4 with a wedge-shaped feeding groove 5, which can make the double-female connectors automatically slide down into the lower vibration slot opening 6 through the wedge-shaped feeding groove 5. The width of the vibration slot opening 6 is smaller than the diameter of the outermost flange of the double-female connector. After the double-female connectors slide down, they are all placed above the vibration slot opening 6 in a lying or tilted posture. The long double-female dovetail rail base body 4 is shaken back and forth along the long side direction of the vibration slot opening 6. The generated vibration cooperates with the center-of-gravity offset of the double-female connector's own structure and the double-female flange surface to realize positioning, so that the double-female connectors are finally uniformly and vertically arranged along the long side of the vibration slot opening 6 for subsequent picking. According to the width of the vibration slot opening 6, the number of double-females poured into the feeding groove at one time can be appropriately selected. After the double-female connectors in the vibration slot opening 6 are uniformly vertical, this row of double-female connectors can be pushed out of the area below the wedge-shaped feeding groove 5, and the above operations are repeated.

[0048] The quick shaping device can automatically vertically arrange different types of double-females to meet the quick shaping and inspection requirements of different double-female sizes. Among them, the double-female shaping holes and mirror shaping holes need to match the structural dimensions of the double-female connectors. The double-female connectors fall into the double-female shaping holes of the round-hole vibrating disk 1 through random vibration and maintain a natural vertical state, which can greatly improve the efficiency of the feeding preparation work; the double-female mirror disk 3 can introduce the double-female connectors that have been shaped and inspected in the round-hole vibrating disk 1 to realize the quick inspection of the other end face of the double-female connectors, greatly improving the inspection time and inspection quality of the double-female connectors; the vibration slot opening 6 needs to match the structural dimensions of the double-female connectors. The double-female connectors automatically slide into the vibration slot opening 6 through the wedge-shaped feeding groove 5, and use the double-female flange surface to realize positioning, so that the double-female connectors are kept in a vertical state, greatly improving the efficiency of the double-female feeding preparation work.

[0049] As Figures 3 - 4 shown, a semi-automatic pneumatic assembly device is used to suck and assemble the double-female connectors shaped by the quick shaping device. It includes a double-female matching head 8, a hollow mounting rod 9, a handle 10, a mounting rod adapter 11, a lightweight air pipe 12, a micro air pump 13 and an adjustable power supply 14. The lightweight air pipe 12, the micro air pump 13 and the adjustable power supply 14 constitute an adjustable air supply device.

[0050] Among them, one end of the double-female matching head 8 is provided with a docking head adapted to the docking interface of the double-female connector for sucking the double-female connector. The hollow mounting rod 9 is connected to the end of the double-female matching head 8 away from the docking head. The handle 10 is mounted on the hollow mounting rod 9 for the user to grip. The mounting rod adapter 11 is connected to the handle 10 for externally connecting an adjustable air supply device. The lightweight air pipe 12 is connected to the mounting rod adapter 11 for guiding air and providing a predetermined moving distance for the double-female matching head 8. The micro air pump 13 is connected to the lightweight air pipe 12 for supplying air. The adjustable power supply 14 is electrically connected to the micro air pump 13 for controlling and adjusting the rotation speed of the micro air pump 13, thereby controlling the suction force on the double-female.

[0051] The hollow mounting rod 9 is a machined steel hollow pipe with a certain strength. When paired with the double-female matching head 8 designed according to the sizes of different double-female adapters, it can achieve air circulation, enabling the generated suction force to act on the flange surface of the double-female connector, thereby realizing the quick and accurate grasping of the double-female connector. The mounting rod adapter 11 is used to connect the hollow mounting rod 9 and lightweight air pipes 12 of different models, achieving the functions of air circulation and sealing. Since the air pipe needs to continuously move its position during the operation, for labor-saving and convenience, the lightweight air pipe 12 is selected as a hose with a light weight. The handle 10 is designed according to ergonomics, making it more convenient and labor-saving for the operator to assemble the double-female. The adjustable power supply 14 can adjust the magnitude of the current and control the rotation speed of the micro air pump 13, thereby controlling the magnitude of the air pressure and realizing the control of the suction force magnitude on the double-female.

[0052] In addition, during the assembly process, after the double-female connector is vertically and stably inserted into the lower assembly surface through the semi-automatic pneumatic assembly device, the air pressure released in the double-female matching head 8 is far from sufficient to pull out the double-female again, and the next double-female assembly work can be carried out smoothly, which has the advantages of continuous work and high efficiency. At the same time, the double-female matching head 8 needs to match the size of the docking interface of the double-female connector. When sucking the double-female connector, the end face of the double-female matching head 8 needs to fit the flange surface of the double-female connector to ensure the stable and reliable picking up of the double-female connector. This device is small in size and light in weight, and each component of the device is detachable and can be carried around, facilitating sharing and use in multiple factory areas or outdoor fields.

[0053] By designing a quick shaping device adapted to double-female connectors with different structural sizes, the present invention can achieve the automatic, unified, and uniform vertical arrangement of double-female connectors, greatly improving the inspection and grasping speed of the end faces of double-female connectors. The hollow mounting rod 9 and the double-female matching head 8 are used to directly apply the acting force to the flange of the double-female connector. By using the micro air pump 13 to extract air, the automatic suction of a single double-female connector is realized. The acting force is directly and evenly applied to the flange surface through the hollow mounting rod 9, realizing the reliable installation of the double-female connector and the base. Finally, a man-machine collaborative installation mode for double-female connectors is achieved, greatly improving the production efficiency and assembly quality.

[0054] Based on the sucking type quick assembly device with a double female connector, the present invention also proposes an assembly method for the double female connector, which specifically includes the following steps:

[0055] Step 1. Operation preparation: Assemble the double female matching head 8, hollow mounting rod 9, handle 10, mounting rod adapter 11, lightweight air pipe 12, micro air pump 13 and adjustable power supply 14 as required, turn on the power supply, check that the air pressure is good during the trial, check that the end face of the double female matching head 8 is intact and without damage, and clean the wedge-shaped feeding groove 5, vibration notch 6 and double female matching head 8.

[0056] Step 2. Double female shaping and inspection: Pour a predetermined number of double females into the double female quick shaping device, perform vibration shaping, and check the end face of the double female connector.

[0057] Step 3. Double female sucking: Turn on the adjustable power supply 14 and adjust the suction force. Align the end face of the double female matching head 8 with the end of the double female connector, and vertically suck it up to ensure that the flange face is aligned with the double female matching head 8 without skew and the suction is stable.

[0058] Step 4. Double female installation: Align the end of the sucked double female connector with the interface of the printed circuit board for butt insertion, insert the double female with appropriate force, remove the handle 10, and the installation is completed.

[0059] Among them, Step 2 further includes the following specific steps according to the types of double female connectors:

[0060] If the double female connector to be assembled has symmetric ends and the butt insertion surfaces do not need to be distinguished, then:

[0061] 1. First, select a round hole vibrating disk 1 adapted to the size of the double female connector, and a leak-proof cover plate 2 and a double female mirror disk 3 adapted to the size of the round hole vibrating disk 1.

[0062] 2. Pour a predetermined number of double female connectors into the round hole vibrating disk 1, cover the leak-proof cover plate 2 on the round hole vibrating disk 1, and shake it back and forth several times.

[0063] 3. Open the leak-proof cover plate 2, and use a semi-automatic pneumatic assembly device to place the unshaped double female into the double female shaping hole in the round hole vibrating disk 1.

[0064] 4. Check the end face of the double female in the round hole vibrating disk 1. If the end face is intact, proceed to the following steps. If the end face is damaged, first use a semi-automatic pneumatic assembly device to take out the double female with a damaged end face, and then proceed to the following steps.

[0065] V. Cover the double-female mirror disk 3 on the round-hole vibrating disk 1 and turn it over so that the double-female mirror disk 3 is placed below the round-hole vibrating disk 1. Then turn on the round-hole vibrating disk 1 to check the other end face of the double-female connector in the double-female mirror disk 3. If the end face is intact, proceed to the subsequent steps. If the end face is damaged, first use a semi-automatic pneumatic assembly device to remove the double-female with a damaged end face, and then proceed to the subsequent steps.

[0066] Embodiment 1

[0067] As Figures 5 - 7 shown, taking the dense arrangement and assembly of a micro double-female connector with a length of 3.9 mm and a diameter of 2.2 mm as an example, the distance between each double-female connector does not exceed 2 mm. It is difficult for general assembly tools for double-female connectors to assemble quickly and with high quality. The double-female structure is symmetric at both ends as shown in Figure 5 (a), and it can be inserted directly without distinguishing the two end faces. According to the double-female structure dimensions, a fast shaping device that can make the double-females automatically arranged vertically is designed, and a round-hole vibrating disk 1 as shown in Figure 6 (b) is designed. The disk diameter is 90 mm, the single-hole diameter is 2.7 mm, and the leak-proof cover plate 2 and the double-female mirror disk 3 are sized to match the round-hole vibrating disk 1. At the same time, the round-hole vibrating disk 1 can appropriately expand and contract the disk body diameter according to the one-time assembly quantity. Figure 6 (b). The disk diameter is 90 mm, the single-hole diameter is 2.7 mm, and the leak-proof cover plate 2 and the double-female mirror disk 3 are sized to match the round-hole vibrating disk 1. At the same time, the round-hole vibrating disk 1 can appropriately expand and contract the disk body diameter according to the one-time assembly quantity.

[0068] In this embodiment, the semi-automatic pneumatic assembly device is composed of a double-female matching head 8, a hollow mounting rod 9, a handle 10, a mounting rod adapter 11, a lightweight air pipe 12, a micro air pump 13, and a 12V adjustable power supply 14. Among them, the double-female matching head 8 is designed in the form of a boss with an inner diameter of 1.7 mm and an outer diameter of 2.3 mm according to the double-female size. As shown in Figure 6 (a), when sucking the double-female, the end face of the double-female matching head 8 is the flange surface in contact with the double-female. The handle 10 is designed according to ergonomics to make it more convenient and labor-saving for the operator to assemble the double-female.

[0069] The specific operation steps of this embodiment are as follows:

[0070] 1. Operation preparation: Assemble the double-female matching head 8, the hollow mounting rod 9, the handle 10, the mounting rod adapter 11, the lightweight air pipe 12, the micro air pump 13, and the adjustable power supply 14 as required, connect the power supply, check that the air pressure is good during the trial, check that the end face of the double-female matching head 8 is intact and without damage, and clean the round-hole vibrating disk 1, the middle hole of the double-female mirror disk 3, and the double-female matching head 8.

[0071] 2. Double-female shaping and inspection: Pour a certain amount of double-female connectors directly into the round-hole vibrating tray 1, cover it with the leak-proof cover plate 2, randomly shake the round-hole vibrating tray 1 by hand for about 5 - 10 seconds, open the leak-proof cover plate 2, remove the excess double-female connectors that have not fallen into the holes, and then the double-female connectors can be automatically vertically arranged. Visually inspect the state of the double-female end face to be intact, cover the double-female mirror tray 3, and introduce the double-female connectors that have been shaped and inspected into the double-female mirror tray 3 to check the state of the other end face of the double-female connectors.

[0072] 3. Double-female picking: By adjusting the pressure of the adjustable power supply 14, align the end face of the double-female matching head 8 with the double-female connectors in the double-female mirror tray 3, and vertically pick them up to ensure that the flange surface is aligned with the double-female matching head 8.

[0073] 4. Double-female installation: Align the double-female connectors with the interface on the printed circuit board surface, insert the double-female connectors with appropriate force, and then remove the double-female matching head 8 to complete the installation.

[0074] If the double-female to be assembled is asymmetric at both ends and the mating surface needs to be distinguished, then:

[0075] I. First, select the wedge-shaped feeding groove 5 and the vibrating notch 6 that are adapted to the size of the double-female connectors.

[0080] Example 2

[0081] As Figure 7 shown, taking the assembly of a double-female connector with a length of 22.8 mm and a diameter of 5.5 mm as an example, this double-female connector is asymmetric at both ends and the mating surface needs to be distinguished, and it is relatively large in size. According to Figure 7 (a) The double-female structure design enables a fast shaping device for automatic vertical arrangement of double-females. Among them, the size of the wedge-shaped feeding groove 5 is as Figure 7(As shown in (b), the inclination angle of the wedge-shaped feeding chute 5 is 45°, the upper width of the opening is 6 mm, the lower width is 8 mm, the opening of the vibrating chute 6 is 4.7 mm, and the length is 200 mm. At the same time, the length of the vibrating chute 6 can be extended or shortened according to the amount of one operation.)

[0082] In this embodiment, the semi-automatic pneumatic assembly device is composed of a double-female matching head 8, a hollow mounting rod 9, a handle 10, a mounting rod adapter 11, a lightweight air pipe 12, a micro air pump 13, and a 12V adjustable power supply 14. Among them, the double-female matching head 8 is designed in the form of a boss with an inner diameter of 4.1 mm and an outer diameter of 6.1 mm according to the double-female size. As Figure 7 (As shown in (a) when sucking the double-female, the end face of the double-female matching head 8 contacts the flange surface of the double-female. The handle 10 is designed according to ergonomics, making it more convenient and labor-saving for the operator to assemble the double-female.)

[0083] The specific operation steps of this embodiment are as follows:

[0084] 1. Operation preparation: Assemble the double-female matching head 8, hollow mounting rod 9, handle 10, mounting rod adapter 11, lightweight air pipe 12, micro air pump 13, and adjustable power supply 14 as required, turn on the power supply, check that the air pressure is good, check that the end face of the double-female matching head 8 is intact without damage, and clean the wedge-shaped feeding chute 5, vibrating chute 6, and double-female matching head 8.)

[0085] 2. Double-female shaping and inspection: Pour a certain amount of double-female connectors directly into the wedge-shaped feeding chute 5. After the double-female connectors slide down along the side wall of the wedge-shaped feeding chute 5, they are all placed above the vibrating chute 6 in a lying or tilted posture. Shake the long double-female dovetail guide base 4 back and forth along the long side direction of the vibrating chute 6 by hand. Use the center-of-gravity offset of the double-female connector's own structure and the double-female flange surface to achieve positioning, so that the double-females finally uniformly maintain a vertical arrangement along the side of the vibrating chute 6. Gently push the arranged double-females out of the area below the wedge-shaped feeding chute 5 by hand, and continue to pour a certain amount into the wedge-shaped feeding chute 5 and repeat the above operation until the vibrating chute 6 is basically full, and visually check that the end face state of the double-females is intact.)

[0086] 3. Double-female sucking: Adjust the pressure of the adjustable power supply 14, align the end face of the double-female matching head 8 with the double-female connectors in the vibrating chute 6, and vertically suck them up to ensure that the double-female flange surface is aligned with the double-female matching head 8 without skew and the sucking is stable.)

[0087] 4. Double-female installation: Align the double-female with the interface of the printed circuit board for insertion, insert the double-female connector with appropriate force, and remove the double-female matching head 8 to complete the installation.)

[0088] The sucking-type rapid assembly device and assembly method of the double-female connector proposed by the present invention can effectively solve the problems in the double-female assembly process, such as low inspection efficiency of the double-female end face, slow feeding speed, risk of damaging the double-female and the assembly surface during installation, and high installation labor intensity and low efficiency. It avoids the problem of interference of the assembly tool with the surrounding double-females in the compact structure design and blind installation scenarios, ensures the vertical insertion of the double-female into the lower assembly surface, and makes the operation more convenient.

[0089] In the above-listed embodiments, the methods of double-female shaping include but are not limited to structural forms such as the round-hole vibrating bowl 1 and the vibrating notch 6. The purpose of double-female shaping is to arrange the double-females regularly, facilitate subsequent direct sucking by the double-female matching head 8, and improve the assembly efficiency.

[0090] The present invention is not limited to the above specific implementation manners, and the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made to the above implementation manners based on the technical essence of the present invention shall be included in the protection scope of the present invention.
