Description

Technical Field

[0001] This invention relates to the field of automatic assembly of retaining rings, and more specifically to an automatic assembly unit for C-type retaining rings made of steel wire. Background Technology

[0002] Snap rings, also known as retaining rings or retaining rings, are common fasteners in mechanical assembly. They are installed in shaft grooves or hole grooves to prevent axial displacement of related parts. In many fields, such as pyrotechnic assembly, snap ring assembly is an important process. However, traditional pyrotechnic snap ring assembly is usually done manually. For small-sized products and snap rings, manual assembly is difficult and inefficient, unable to meet the needs of mass production, and also prone to safety hazards. Furthermore, the assembly method commonly used in the civilian industry, which involves using external support fixtures and pressure heads to assemble circlips, is not suitable for assembling small-sized products and circlips. For example, the steel wire C-type circlips commonly used in the pyrotechnics field are characterized by their small size, ultra-light weight, and ease of material connection. Existing assembly methods struggle to ensure accurate connection between small-sized pyrotechnics and small-sized steel wire C-type circlips. Moreover, due to the small size and ultra-light weight of these circlips, press-fitting or similar methods cannot be used during assembly. Additionally, existing assembly methods make it difficult to effectively separate these springs during circlip feeding. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic assembly unit for steel wire C-type retaining rings, which can achieve accurate docking and reliable assembly of small-sized pyrotechnic components and small-sized C-type retaining rings, while also ensuring effective separation when the C-type retaining rings are fed into the material.

The C-type retaining ring to be assembled is thrown out from the throwing port on the throwing cylinder and falls into the retaining ring dropping groove through the dropping hopper. The retaining ring cone sleeve positioning mechanism includes a retaining ring cone sleeve and upper and lower clamps that can be raised and lowered synchronously. The upper end of the retaining ring cone sleeve is connected by the upper and lower clamps. The C-shaped retaining ring in the retaining ring dropping groove is fed to the upper end of the retaining ring cone sleeve by the retaining ring transfer mechanism. Then, it falls to the upper side of the lower retaining ring by the upper clamping hand of the cone sleeve, and then falls to the expanded diameter part of the lower end of the retaining ring cone sleeve by the lower clamping hand of the cone sleeve. The retaining ring assembly mechanism includes an assembly lifting seat, and the assembly lifting seat is equipped with a guide wheel and a pressing claw that can move open and close. During assembly, the lower end of the retaining ring cone sleeve is held by the guide wheel and the pressing claw. The pyrotechnic product to be assembled is fed to the lower end of the retaining ring cone sleeve by the pyrotechnic product feeding system. Then, the C-shaped retaining ring at the lower end of the retaining ring cone sleeve is pressed into the retaining groove on the pyrotechnic product by the pressing claw.

[0005] The snap ring throwing mechanism includes a throwing cover and a throwing motor.

[0010] The pyrotechnic feeding system includes a pyrotechnic feeding mechanism, a pyrotechnic suction and release mechanism, and a station turntable mechanism. The pyrotechnic suction and release mechanism includes a suction pipe and an outlet lifting seat. The outlet lifting seat is equipped with a vacuum generator, a pyrotechnic outlet pipe, and a shielding cylinder. The input end of the suction pipe is connected to the pyrotechnic feeding mechanism, and the output end is located on the outlet lifting seat and aligned with the inlet of the pyrotechnic outlet pipe.

The station turntable mechanism includes a turntable, and multiple pyrotechnic clamping devices are arranged circumferentially on the turntable. During assembly, the pyrotechnics output from the pyrotechnic outlet pipe first fall into the corresponding pyrotechnic clamping device and are fixed, and then moved by the turntable to the pressing jaws of the snap ring assembly mechanism.

[0011] The pyrotechnic concentrator includes a concentrator support, on which an outlet lifting cylinder and a fixed base are provided.

[0013] The snap ring assembly mechanism is provided with a finished product unloading system on the side away from the pyrotechnics feeding system. The finished product unloading system includes a finished product pallet mechanism and a finished product unloading mechanism. The finished product pallet mechanism includes a movable finished product pallet, and the finished product unloading mechanism includes a movable unloading claw. After the finished parts assembled on the turntable are rotated to the unloading station, they are picked up by the unloading claw and sent to the finished product pallet.

[0014] The advantages and positive effects of this invention are as follows: 1. This invention utilizes a snap ring cone sleeve positioning mechanism to support the C-type snap ring to be assembled, and uses the snap ring cone sleeve to align with the pyrotechnic component. Then, the invention employs a guide wheel and a pressing gripper in the snap ring assembly mechanism to move and fit the C-type snap ring into the pyrotechnic component's slot. The guide wheel rolls along the snap ring cone sleeve and limits the position of the lower end of the snap ring cone sleeve to prevent it from shifting. The pressing gripper performs the pressing assembly work on the C-type snap ring. During the pressing assembly process, the gradually increasing diameter of the lower end of the snap ring cone sleeve allows the C-type snap ring to gradually open. Thus, when the C-type snap ring disengages from the expanding diameter section, it automatically closes and locks into the pyrotechnic component's slot. This invention, through the above structural design, achieves accurate docking and automated assembly of micro-sized pyrotechnic components and micro-sized C-type snap rings, improving the level of automation and assembly efficiency while ensuring assembly quality.

[0015] 2. This invention utilizes a circlip throwing mechanism to achieve effective separation during the feeding of C-type circlips. The rotating throwing cylinder in the circlip throwing mechanism throws the C-type circlips one by one into the hopper, thus achieving the first separation of the C-type circlips. Then, the lower outlet of the hopper outputs only one or a few C-type circlips at a time, thus achieving the second separation of the C-type circlips. At the same time, it also allows the C-type circlips to fall into the circlip dropping groove on the circlip dropping platform. This can meet the feeding needs of subsequent automatic assembly of individual C-type circlips and prevent the C-type circlips from getting stuck together.

[0016] 3. This invention utilizes a snap ring feeding platform mechanism and a snap ring transfer mechanism to meet the conveying needs of a single C-type snap ring. The snap ring feeding platform mechanism, through the movement of the snap ring feeding platform, can place the C-type snap rings output from the feeding hopper in a straight line in the snap ring feeding groove. Then, the snap ring transfer nozzle in the snap ring transfer mechanism, which has the freedom of movement and lifting, can pick up a single C-type snap ring from the snap ring feeding groove and send it to the snap ring cone sleeve. This realizes the automatic and continuous feeding of a single C-type snap ring.

[0017] 4. The present invention has a snap ring sorting vision camera on one side of the snap ring unloading platform mechanism. When the snap ring unloading platform moves to the bottom of the snap ring sorting vision camera, the snap ring sorting vision camera cooperates to detect whether the position of the C-type snap ring in the snap ring unloading groove meets the requirements, thereby ensuring that the snap ring transfer nozzle accurately picks up the C-type snap ring. At the same time, the upper end of the snap ring cone sleeve is provided with a snap ring guide plate with a snap ring guide hole, so that the C-type snap ring can pass through the snap ring guide hole and be accurately fitted onto the upper end of the snap ring cone sleeve. The above structural design further ensures the smooth feeding of individual C-type snap rings and avoids situations such as the C-type snap ring not being accurately fitted onto the upper end of the snap ring cone sleeve.

[0018] 5. In addition to the automatic continuous feeding of a single C-shaped retaining ring, the present invention can also achieve automatic continuous feeding of pyrotechnic items through a pyrotechnic item feeding system. The pyrotechnic item feeding system uses a suction pipe in the pyrotechnic item suction and release mechanism to suck in individual pyrotechnic items for feeding. A discharge baffle is provided between the connecting pipe at the output end of the suction pipe and the pyrotechnic item outlet pipe to ensure the output of pyrotechnic items one by one in accordance with the production rhythm. At the same time, this air suction feeding method is particularly suitable for the feeding needs of the small-sized and ultra-lightweight pyrotechnic items targeted by the present invention. The station turntable mechanism in the pyrotechnic item feeding system realizes the sequential transfer of each pyrotechnic item to the station through the rotation of the turntable, thereby further improving the automation level of the assembly of the present invention.

[0019] 6. The pyrotechnic feeding system of the present invention utilizes a material box tray with multiple degrees of freedom of movement in the pyrotechnic feeding mechanism in conjunction with a suction pipe to achieve feeding. Furthermore, the protective shell of the pyrotechnic feeding mechanism is equipped with a pyrotechnic sorting vision camera to detect the position of the pyrotechnics in real time to ensure accurate feeding. At the same time, the protective shell can also provide sufficient protection.

[0020] 7. The present invention has a finished product unloading system on the side of the snap ring assembly mechanism away from the pyrotechnics feeding system, and the finished product unloading system, together with the station turntable mechanism, can realize the automatic unloading of the assembled finished parts, thereby further improving the automation level of the present invention.

Detailed Implementation

[0023] The invention will now be described in further detail with reference to the accompanying drawings.

[0024] like Figures 1-24As shown, the present invention includes a snap ring throwing mechanism 1, a snap ring dropping platform mechanism 3, a snap ring transfer mechanism 7, a snap ring cone sleeve positioning mechanism 9, a pyrotechnics feeding system, and a snap ring assembly mechanism 10, wherein as... Figures 2-3 As shown, the snap ring throwing mechanism 1 includes a throwing cylinder 101 and a dropping hopper 103, as follows: Figure 5 As shown, the snap ring unloading platform mechanism 3 includes a snap ring unloading platform 302, which is provided with a snap ring unloading groove 303. The C-type snap ring 306 is thrown out from the throwing port 1011 on the throwing cylinder 101 and falls into the snap ring unloading groove 303 through the unloading hopper 103; Figures 13-16 As shown, the snap ring cone sleeve positioning mechanism 9 includes a snap ring cone sleeve 904 and an upper snap ring clamp 902 and a lower snap ring clamp 903 that can be raised and lowered synchronously. The upper end of the snap ring cone sleeve 904 is held by the upper snap ring clamp 902 and the lower snap ring clamp 903. The C-shaped snap ring 306 in the snap ring drop groove 303 is sent to the upper end of the snap ring cone sleeve 904 by the snap ring transfer mechanism 7. Then, the C-shaped snap ring 306 first slides along the upper end of the snap ring cone sleeve 904 and lands on the upper side of the lower snap ring clamp 903 through the opening and closing of the upper snap ring clamp 902. Then, it falls to the lower end of the snap ring cone sleeve 904 through the opening and closing of the lower snap ring clamp 903. In the above actions, since the upper snap ring clamp 902 and the lower snap ring clamp 903 open and close sequentially, the upper end of the snap ring cone sleeve 904 can always be kept in a clamped state, and the snap ring cone sleeve 904 will not fall off. Figures 17-19 As shown, the snap ring assembly mechanism 10 includes an assembly lifting seat 1007, and the assembly lifting seat 1007 is provided with a guide wheel 1003 for opening and closing movement and a pressing gripper 1005 for opening and closing movement, as shown. Figure 21 As shown, during assembly, the lower end of the snap ring cone sleeve 904 is held by the guide wheel 1003 and the pressing jaw 1005, and the pyrotechnic item 802 is fed to the bottom of the snap ring cone sleeve 904 through the pyrotechnic item feeding system. Then, the C-shaped snap ring 306 at the lower end of the snap ring cone sleeve 904 is pressed down and fitted into the slot on the pyrotechnic item 802 by the pressing jaw 1005.

[0025] like Figures 2-3As shown, in this embodiment, the snap ring throwing mechanism 1 includes a throwing shield 102 and a throwing motor 104. The throwing shield 102 is located at the upper inlet of the dropping hopper 103, and the lower outlet of the dropping hopper 103 is aligned with the snap ring dropping groove 303 on the snap ring dropping platform 302. The throwing motor 104 is mounted on the throwing shield 102, and the throwing cylinder 101 is located in the throwing shield 102 and is driven to rotate by the throwing motor 104. The end of the throwing cylinder 101 near the throwing motor 104 has multiple throwing ports 1011 along the circumferential direction. In operation, the C-type retaining ring 306 is stored in the throwing cylinder 101. The throwing motor 104 drives the throwing cylinder 101 to rotate in a pulse manner, thereby throwing individual C-type retaining rings 306 out of their corresponding throwing ports 1011 and into the discharge hopper 103, thus achieving one separation of the C-type retaining rings 306. During the throwing process, the throwing shield 102 can prevent the C-type retaining rings 306 from being thrown out and ensure they only fall into the discharge hopper 103. And as... Figure 3 As shown, the hopper 103 is generally a cone-shaped hopper that is wider at the top and narrower at the bottom. The lower outlet of the hopper 103 ensures that only one or a few C-type snap rings 306 are output and fall into the snap ring discharge groove 303 at a time, thereby realizing the secondary separation of the C-type snap rings 306.

[0026] like Figure 2 As shown, in this embodiment, a fixing plate 105 is provided on one side of the hopper 103 to fix the snap ring throwing mechanism 1 on the corresponding frame, and a brush 106 is provided at the lower end of the hopper 103 to cooperate with the movement of the snap ring dropping platform 302 to clean the residual material in the snap ring dropping groove 303.

[0027] like Figure 5 As shown, in this embodiment, the snap ring unloading platform mechanism 3 includes a unloading platform moving module 301, and the snap ring unloading platform 302 is driven to move by the unloading platform moving module 301. The snap ring unloading platform 302 has snap ring cleaning ramps 304 at both ends and a snap ring receiving box 305 on one side, and the snap ring cleaning ramps 304 are connected to the snap ring unloading groove 303 and the snap ring receiving box 305. When cleaning up residual material, the snap ring unloading platform 302 moves and the remaining C-shaped snap rings 306 are swept into the snap ring cleaning ramps 304 on both sides by the brush 106 at the lower end of the unloading hopper 103. Then, the C-shaped snap rings 306 slide into the snap ring receiving box 305 along the snap ring cleaning ramps 304 under the action of gravity. In this embodiment, the material dropping platform moving module 301 can be a rodless cylinder, the snap ring material dropping platform 302 is fixedly connected to the slider on the rodless cylinder, and the snap ring receiving box 305 is detachably provided on the snap ring material dropping platform 302.

[0028] like Figures 10-11As shown, in this embodiment, the snap ring transfer mechanism 7 includes a snap ring transfer module 701, a snap ring lifting and transfer cylinder 703, and a snap ring transfer nozzle 702. The snap ring lifting and transfer cylinder 703 is driven to move by the snap ring transfer module 701, and the snap ring transfer nozzle 702 is driven to rise and fall by the snap ring lifting and transfer cylinder 703. When the invention is working, as... Figure 5 As shown, due to the movement and coordination of the snap ring unloading table 302, each C-shaped snap ring 306 can fall into the snap ring unloading groove 303 in a straight line. Thus, each time the snap ring transfer nozzle 702 moves and descends to the set position, it can accurately pick up a single C-shaped snap ring 306, and then rises and, through the movement of the snap ring transfer module 701, delivers the picked-up single C-shaped snap ring 306 to the upper end of the snap ring cone sleeve 904 of the snap ring cone sleeve positioning mechanism 9. Additionally, as... Figure 1 and Figure 8 As shown, the present invention includes a snap ring sorting vision camera 4 for real-time detection of the C-type snap rings 306 in the snap ring discharge groove 303. The snap ring transfer nozzle 702 only picks up the C-type snap ring 306 when the C-type snap ring 306 meets the suction conditions. Figure 24 As shown, in this embodiment, the snap ring sorting vision camera 4 is mounted on a camera mounting base 401. Additionally, in this embodiment, the snap ring transfer module 701 can be a rodless cylinder, and the snap ring lifting and transfer cylinder 703 is mounted on the slider of the rodless cylinder.

[0029] like Figures 13-16 As shown, in this embodiment, the snap ring cone sleeve positioning mechanism 9 includes a cone sleeve lifting module 901, and a cone sleeve lifting seat 905 is provided on the cone sleeve lifting module 901. An upper cone sleeve gripper 902 and a lower cone sleeve gripper 903 are both provided on the cone sleeve lifting seat 905; Figure 16 As shown, the upper end of the conical sleeve lifting seat 905 is provided with a snap ring guide plate 906, and the upper end of the snap ring conical sleeve 904 is a conical end 9041. The front end of the snap ring guide plate 906 is provided with a snap ring guide hole 9061 aligned with the conical end 9041. During operation, a single C-shaped snap ring 306 is delivered to the area above the snap ring guide hole 9061 via the snap ring transfer nozzle 702 in the snap ring transfer mechanism 7. Then, the conical sleeve lifting module 901 lifts the snap ring conical sleeve 904, allowing the conical end 9041 of the snap ring conical sleeve 904 to enter the hole of the snap ring transfer nozzle 702. Afterward, the snap ring transfer nozzle 702 releases the C-shaped snap ring 306. In this embodiment, the conical sleeve lifting module 901 can be a rodless cylinder or other suitable linear lifting drive device.

[0030] like Figure 16As shown, the cone sleeve lifting seat 905 is equipped with an upper clamping jaw opening and closing cylinder and a lower clamping jaw opening and closing cylinder. The upper clamping jaw 902 of the cone sleeve is driven to open and close by the upper clamping jaw opening and closing cylinder, and the lower clamping jaw 903 of the cone sleeve is driven to open and close by the lower clamping jaw opening and closing cylinder. The inner shapes of the upper clamping jaw 902 and the lower clamping jaw 903 of the cone sleeve need to be designed to match the shape of the tapered end 9041 at the upper end of the snap ring cone sleeve 904 to ensure reliable clamping of the tapered end 9041. In operation, after the C-type retaining ring 306 is released by the retaining ring transfer nozzle 702, the C-type retaining ring 306 is first fitted onto the conical end 9041 and falls along the conical end 9041 onto the upper side of the upper clamp 902 of the conical sleeve. Then, the upper clamp 902 of the conical sleeve opens to allow the C-type retaining ring 306 to continue moving and fall onto the lower clamp 903 of the conical sleeve. After the C-type retaining ring 306 has passed, the upper clamp 902 of the conical sleeve closes to ensure the clamping of the conical end 9041. Then, the lower clamp 903 of the conical sleeve opens to allow the C-type retaining ring 306 to pass and continue moving along the retaining ring conical sleeve 904 until it falls onto the lower end of the retaining ring conical sleeve 904. The lower clamp 903 of the conical sleeve also closes after the C-type retaining ring 306 has passed to ensure the clamping of the conical end 9041. Additionally, as... Figure 9 As shown, the present invention includes a circlip blanking vision camera 6 for real-time detection of whether the C-type circlip 306 is accurately fitted onto the circlip cone sleeve 904, thereby ensuring smooth assembly. The circlip blanking vision camera 6 is a commercially available product and is installed on a corresponding frame.

[0031] like Figure 15 and Figure 21 As shown, in this embodiment, the lower end of the snap ring cone sleeve 904 is provided with an enlarged diameter portion 9042 with a gradually increasing diameter. The C-type snap ring 306 moves along the snap ring cone sleeve 904 and falls onto the enlarged diameter portion 9042. The enlarged diameter portion 9042 needs to have a sufficient diameter so that the C-type snap ring 306 will not fall off. On the other hand, the diameter should not be too large so that the pressing claw 1005 in the snap ring assembly mechanism 10 can press down the C-type snap ring 306 to move along the enlarged diameter portion 9042 and finally be locked into the slot on the pyrotechnic item 802.

[0032] like Figures 17-19As shown, in this embodiment, the snap ring assembly mechanism 10 includes an assembly mounting plate 1004, and an assembly lifting module 1001 is provided on the upper side of the assembly mounting plate 1004. The assembly lifting seat 1007 is driven to lift and lower through the assembly lifting module 1001. In addition, the snap ring cone sleeve lifting module 901 in the snap ring cone sleeve positioning mechanism 9 is also provided on the assembly mounting plate 1004 and is located on one side of the assembly lifting module 1001. In this way, the snap ring cone sleeve 904 driven to lift and lower through the cone sleeve lifting module 901, as well as the guide wheel 1003 and the pressing jaw 1005 driven to lift and lower through the assembly lifting module 1001, can cooperate to adjust the height to ensure that the guide wheel 1003 and the pressing jaw 1005 can accurately and reliably clamp the lower end of the snap ring cone sleeve 904 at the assembly station. In this embodiment, the assembly lifting module 1001 can also be a rodless cylinder or other suitable linear lifting drive device.

[0033] like Figures 17-19 As shown, in this embodiment, the assembly lifting seat 1007 is equipped with a guide wheel opening and closing cylinder 1002 and a pressing gripper cylinder 1006. Two guide wheels 1003 are driven to open and close by the guide wheel opening and closing cylinder 1002, and two pressing grippers 1005 are driven to open and close by the pressing gripper cylinder 1006. Furthermore, during assembly, the two guide wheels 1003 clamp the main body of the snap ring cone sleeve 904 and can roll along the snap ring cone sleeve 904. Figure 21 As shown, two pressing jaws 1005 clamp the expanded diameter portion 9042 and drive the C-shaped retaining spring 306 downward along the expanded diameter portion 9042. Since the diameter of the expanded diameter portion 9042 gradually increases, the C-shaped retaining spring 306 will open during the pressing process. When the C-shaped retaining spring 306 enters the slot at the upper end of the pyrotechnic item 802, it automatically closes and fits into the slot because it has disengaged from the expanded diameter portion 9042. The inner side of the pressing jaws 1005 needs to be designed to match the shape of the expanded diameter portion 9042.

A discharge baffle 2031 is provided between the output end of the suction pipe 201 and the inlet of the pyrotechnic outlet pipe 205, and the discharge baffle 2031 is moved by the shielding cylinder 203. Figure 9 and Figures 18-19 As shown, the workstation turntable mechanism 8 includes a turntable 801, and multiple pyrotechnic clamping devices 803 are arranged along the circumferential direction on the turntable 801. The pyrotechnic 802 output from the pyrotechnic outlet pipe 205 first falls into the corresponding pyrotechnic clamping device 803 and is fixed, and then is moved by the turntable 801 to below the pressing claw 1005 of the snap ring assembly mechanism 10. In this embodiment, the pyrotechnic clamping device 803 can be fixed by a claw cylinder. In addition, the turntable 801 is located on the lower side of the mounting plate 1004 of the snap ring assembly mechanism 10 and is driven to rotate by a servo motor.

When the present invention is in operation, the material box tray 503 first extends to a set position outside the protective housing 501, and then the pyrotechnic material box 802 containing the pyrotechnic material 802 is placed on the material box tray 503. Then the material box tray 503 retracts into the protective housing 501 and moves to the loading station. The pyrotechnic material sorting vision camera 505 identifies whether the position of the pyrotechnic material 802 is aligned with the connecting pipe opening. After alignment, the suction pipe 201 is activated to suck in one pyrotechnic material 802. Then the material box tray 503 moves in coordination to align the next pyrotechnic material 802 with the connecting pipe opening.

[0038] like Figure 7 As shown, in this embodiment, the protective housing 501 internally houses a pyrotechnic Y-axis module 507, a pyrotechnic X-axis module 508, and a telescopic cylinder 506.

[0039] like Figure 1 As shown, the snap ring assembly mechanism 10 has a finished product unloading system on the side away from the pyrotechnics loading system. In this embodiment, the finished product unloading system includes a finished product tray mechanism 11 and a finished product unloading mechanism 13, wherein... Figure 22 As shown, the finished product pallet mechanism 11 includes a movable finished product pallet 1102, and the finished product pallet 1102 is provided with a receiving groove for accommodating the assembled finished product component 1101, such as... Figure 23As shown, the finished product unloading mechanism 13 includes a movable unloading gripper 1302, and the finished product component 1101 on the station turntable mechanism 8 is picked up by the unloading gripper 1302 and sent to the finished product tray 1102. In addition, when the present invention is working, after the pyrotechnic component 802 on the pyrotechnic component clamping device 803 corresponding to the lower end of the stencil assembly mechanism 10 in the station turntable mechanism 8 completes the assembly of the C-type stencil 306 to form the finished product component 1101, the turntable 801 rotates to rotate the finished product component 1101 to the unloading station on the other side, and then the unloading gripper 1302 picks up the finished product component 1101 and sends it to the finished product tray 1102.

[0040] like Figure 22 As shown, in this embodiment, the finished product pallet mechanism 11 includes a lower cylinder 1106, a lower slide plate 1104, an upper cylinder 1103, and an upper slide plate 1107.

The movable seat is equipped with an unloading gripper cylinder, and the unloading gripper 1302 is driven to open and close by the unloading gripper cylinder.

[0042] In addition, the present invention can set the number of pyrotechnic suction and release mechanism 2, pyrotechnic feeding mechanism 5 and finished product tray mechanism 11 according to actual needs to further improve work efficiency. In this embodiment, the number of pyrotechnic suction and release mechanism 2, pyrotechnic feeding mechanism 5 and finished product tray mechanism 11 are all set to two sets, so that the system can be operated continuously without stopping. When one set needs to stop to replenish materials or for maintenance, the other set can continue to work.

[0043] The working principle of this invention is as follows: The present invention includes the following steps in operation: Step 1: The circlip throwing mechanism 1 rotates to output C-type circlips one by one, and the output C-type circlips 306 fall into the circlip dropping groove 303 of the circlip dropping table 302 through the dropping hopper 103.

[0044] Step 2: The circlip transfer nozzle 702 in the circlip transfer mechanism 7 moves to the suction station and picks up a single C-shaped circlip 306 that meets the suction requirements in the circlip drop groove 303.

[0045] Step 3: The circlip transfer nozzle 702 in the circlip transfer mechanism 7 moves and delivers the picked-up single C-shaped circlip 306 to the circlip cone sleeve 904 in the circlip cone sleeve positioning mechanism 9. Then, the cone sleeve lifting module 901 lifts the circlip cone sleeve 904 so that the tapered end 9041 at the upper end of the circlip cone sleeve 904 enters the hole of the circlip transfer nozzle 702. Then, the circlip transfer nozzle 702 releases the C-shaped circlip 306. The C-shaped circlip 306 passes through the circlip guide hole 9061 at the front end of the circlip guide plate 906 and is fitted onto the tapered end 9041 at the upper end of the circlip cone sleeve 904.

[0046] Step 4: The upper clamp 902 of the cone sleeve in the snap ring cone sleeve positioning mechanism 9 first opens to allow the C-shaped snap ring 306 to pass through and land on the upper side of the lower clamp 903 of the cone sleeve. Then, the upper clamp 902 closes to continue clamping the upper end of the snap ring cone sleeve 904. Then, the lower clamp 903 opens to allow the C-shaped snap ring 306 to pass through. The C-shaped snap ring 306 moves along the snap ring cone sleeve 904 under the action of gravity until it lands on the expanded diameter portion 9042 at the lower end of the snap ring cone sleeve 904. After the C-shaped snap ring 306 passes through, the lower clamp 903 closes to continue clamping the upper end of the snap ring cone sleeve 904.

[0047] Step 5: The pyrotechnic component 802 is fed to the assembly station below the snap ring assembly mechanism 10 through the pyrotechnic component feeding system. Then, the snap ring cone sleeve 904 descends and passes between the two guide wheels 1003 and the two pressing claws 1005 of the snap ring assembly mechanism 10 to align with the upper end of the pyrotechnic component 802 on the assembly station.

[0048] Step Six: Both guide wheels 1003 and two pressing jaws 1005 close and clamp the lower end of the snap ring cone sleeve 904. The two guide wheels 1003 clamp the main body of the snap ring cone sleeve 904 to limit its position, while the two pressing jaws 1005 clamp the expanded diameter portion 9042 at the lower end of the snap ring cone sleeve 904 but do not clamp it tightly, so as to ensure that the C-type snap ring 306 can be pressed down to complete the assembly.

[0049] Step 7: The cone sleeve lifting seat 905 in the snap ring assembly mechanism 10 drives the guide wheel 1003 and the pressing jaw 1005 to descend synchronously. The upper guide wheel 1003 ensures that the lower end of the snap ring cone sleeve 904 does not move. The pressing jaw 1005 presses down on the C-shaped snap ring 306 on the expanded diameter part 9042 to complete the assembly. Since the diameter of the expanded diameter part 9042 gradually increases, the C-shaped snap ring 306 will open during the pressing process. When the C-shaped snap ring 306 disengages from the expanded diameter part 9042 and enters the slot on the pyrotechnic item 802, the C-shaped snap ring 306 automatically closes and locks in the slot, thus completing the assembly.

[0050] Step 8: The finished component 1101 formed by installing the C-type retaining ring 306 on the pyrotechnic product 802 is sent to the unloading station on the other side through the station turntable mechanism 8 in the pyrotechnic product feeding system. Then, the unloading claw 1302 in the finished product unloading mechanism 13 sends the finished component 1101 to the finished product tray 1102 of the finished product tray mechanism 11 to complete the unloading.
