DETAILED DESCRIPTION

[0015] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0016] See also Figures 1 to 25 One embodiment of the present application provides an automated assembly device for a rotary lock pin shaft and automated assembly equipment for the rotary lock. The rotary lock comprises an outer cover, an inner seat, a spring, a shaft, and a pin. Specifically, the automated assembly equipment for the rotary lock is suitable for the automated assembly of the rotary lock (rotary telescopic positioning connection structure) disclosed in Publication No. CN222973300U. Furthermore, the automated assembly device for the rotary lock pin shaft is also suitable for the automated assembly of the shaft and pin of the rotary lock.

[0017] The automatic assembly equipment for the rotary lock includes an automatic assembly device for the rotary lock pin shaft, wherein the equipment platform 145 of the automatic assembly equipment for the rotary lock is equipped with a shaft installation station, a pin installation station, a pin punching station, a pin positioning station, and a pin riveting station around it to form an automatic assembly of the rotary lock pin shaft.

[0018] Automatic assembly equipment for twist locks: equipment table 145, outer cover installation assembly 1 located at the outer cover installation station, inner seat installation assembly 2 located at the inner seat installation station, spring installation assembly 3 located at the spring installation station, shaft installation assembly 4 located at the shaft installation station, pin installation assembly 5 located at the pin installation station, and pin riveting assembly 7 located at the pin riveting station.

[0019] The equipment platform 145 comprises a stationary equipment mounting plate 8 and a controllably driven carrier ring plate 9 that rotates around the exterior of the equipment mounting plate 8. The equipment platform 145 is circumferentially arranged with stations for outer cover installation, inner seat installation, spring installation, shaft installation, pin installation, pin punching, and pin riveting. The mounting plate is fixedly equipped with a pre-insertion punching mechanism 85 corresponding to the shaft installation station, and a pin insertion positioning mechanism 86 corresponding to the pin installation station. The carrier ring plate 9 is fixedly equipped with a plurality of circumferentially distributed fixed carriers 150 equipped with pre-insertion positioning rods 159.

[0020] The disc-shaped equipment table 145 includes a centrally fixed equipment mounting plate 8 and a rotating carrier ring 9 that can be driven by a servo motor or other device for stepwise rotation. Multiple identical fixed carriers 150 are evenly distributed along the circumference of the rotating carrier ring 9 to support the twist locks to be assembled. Around the perimeter of the equipment table 145, multiple workstations are arranged sequentially according to the assembly process flow, including: an outer cover installation station (corresponding to outer cover installation component 1), an inner seat installation station (corresponding to inner seat installation component 2), a spring installation station (corresponding to spring installation component 3), a shaft installation station (corresponding to shaft installation component 4), a pin installation station (corresponding to pin insertion component 5), a pin insertion station (corresponding to pin insertion component 6), and a pin riveting station (corresponding to pin riveting component 7).

[0021] See also Figures 7 to 9 The fixed carrier 150 is a key component for carrying and positioning the semi-finished rotary lock. It includes a carrier front wall 151 and a carrier rear wall 152 relative to each other, and a carrier side wall 155 connecting the two, which together form a carrier groove, and its internal shape matches the outer contour of the outer cover 101. A front wall hole 153 is provided on the carrier front wall 151, and its position corresponds to the pin hole 1011 of the outer cover 101. The pin hole 1011 of the outer cover 101 is a through hole so that the pin 105 can pass through. A rod seat sleeve 158 is fixedly installed on the carrier rear wall 152, and a pre-inserted positioning rod 159 can slide horizontally in this seat sleeve. The rod end of the pre-inserted positioning rod 159 is facing the front wall hole 153 to achieve precise alignment of the subsequent shaft 104 with the hole position of the outer cover 101. A square avoidance groove 154 is further defined on the front wall hole 153 and the rear wall 152 of the carrier to facilitate the clamping claws to clamp the outer cover 101 .

[0022] The outer cover mounting assembly 1 is used to place the outer cover 101 within the fixed carrier 150; the inner seat mounting assembly 2, located at the inner seat mounting station, is used to place the inner seat 102 within the outer cover. The spring mounting assembly 3, located at the spring mounting station, is used to vertically insert the spring 103 into the axial hole of the inner seat 102. The shaft mounting assembly 4, located at the shaft mounting station, includes a shaft mounting mechanism and a shaft conveying mechanism 40 for conveying the shaft 104. The shaft mounting mechanism is used to vertically insert the conveyed shaft 104 into the spring 103; the pre-insertion punching mechanism 85 is used to push the pre-insertion positioning rod 159 through the shaft 104 and the outer cover 101 for pre-positioning when the shaft mounting mechanism inserts the shaft 104 into the hole and aligns it.

[0023] The pin installation assembly 5 located at the pin installation station includes a pin installation mechanism and a pin conveying mechanism 50 for conveying pins. The pin insertion and positioning mechanism 86 is used to press the shaft 104 downward to maintain its current position. The pin installation mechanism is used to horizontally insert the conveyed pin 105 through the shaft 104 and the housing 101 and partially retract the pre-insertion positioning rod 159. The pin riveting assembly 7 located at the pin riveting station is used to rivet and flange one end of the pin to form the finished twist lock.

[0024] To ensure that the pin 105 is inserted into place and to prevent the pre-insertion positioning rod 159 from being fully reset, which could prevent the product from being removed, a pin insertion station is provided on the equipment platform 145 between the pin installation station and the pin riveting station. A positioning mechanism 82 is fixedly provided on the fixed plate corresponding to the pin insertion station. The positioning mechanism 82 is used to press the shaft 104 downward to maintain its current position. The automatic assembly equipment for rotating locks also includes a pin insertion assembly 6 located at the pin insertion station, which is used to push the inserted pin into place and fully reset the pre-insertion positioning rod 159.

[0025] The conveying mechanisms of each part, such as the outer cover conveying mechanism 10, the inner seat conveying mechanism 20, the spring conveying mechanism 30, the shaft conveying mechanism 40 and the pin conveying mechanism 50, are preferably vibrating disk conveying mechanisms, which can organize the scattered parts into an orderly arrangement and convey them to the designated position to wait for the grippers of each workstation to grab them.

[0026] See Figure 13 The outer cover installation assembly 1 includes an outer cover installation mechanism and an outer cover conveying mechanism 10; the outer cover conveying mechanism 10 is used to convey the outer cover 101; the outer cover installation mechanism is used to place the conveyed outer cover 101 into the fixed carrier 150. The outer cover installation assembly 1 is mainly composed of a three-axis motion mechanism. The outer cover moving mechanism 11 is a horizontally arranged linear module that realizes reciprocating motion in the X-axis direction. A outer cover vertical movement mechanism 12 is installed on the slider of the outer cover moving mechanism 11, which is a vertically arranged linear module or cylinder that realizes lifting and lowering in the Z-axis direction. The end of the outer cover vertical movement mechanism 12 is connected to the outer cover conveying mechanism 13, on which is installed an outer cover electric clamp 14 and an outer cover rotating component (such as a rotating motor) for adjusting the posture.

[0027] Specifically, the cover installation mechanism includes: a cover moving mechanism 11, a cover vertical movement mechanism 12 disposed on the cover moving mechanism 11 for horizontal reciprocating movement, and a cover transport mechanism 13 disposed on the cover vertical movement mechanism 12 for vertical reciprocating movement. The cover transport mechanism 13 includes a cover rotating component and an electric cover clamp 14 connected below the cover rotating component. The electric cover clamp 14 is used to clamp the cover 101. The cover rotating component can rotate the electric cover clamp 14 about a vertical axis to rotate the feed material 90 degrees. Multiple cover vertical movement mechanisms 12 are disposed on the cover moving mechanism 11, and each cover vertical movement mechanism 12 is correspondingly provided with a cover transport mechanism 13.

[0028] At this station, the housing conveying mechanism 10 (e.g., a vibrating plate) delivers the housing 101 to the unloading position. The housing electric gripper 14 descends and grabs the housing 101, which is then lifted by the housing vertical shifting mechanism 12. The housing moving mechanism 11 then translates horizontally to directly above the fixed carrier 150. If necessary, the housing rotation component rotates the housing 90 degrees horizontally to adjust its position. Finally, the housing vertical shifting mechanism 12 descends, precisely placing the housing 101 into the carrier slot.

[0029] See Figure 13 The inner seat mounting assembly 2 includes an inner seat mounting mechanism and an inner seat conveying mechanism 20. The inner seat conveying mechanism 20 is used to transport the inner seat 102; the inner seat mounting mechanism is used to place the transported inner seat 102 onto the outer cover 101 on the fixed carrier 150. The structure of the inner seat mounting assembly 2 is essentially the same as that of the outer cover mounting assembly 1. It also includes an inner seat moving mechanism 21 for horizontal movement, an inner seat vertical movement mechanism 22 for vertical lifting, and an inner seat transport mechanism 23 with an inner seat electric gripper 24 at its end.

[0030] Specifically, the inner seat installation mechanism includes: an inner seat moving mechanism 21, an inner seat vertical movement mechanism 22 that is horizontally reciprocatingly mounted on the inner seat moving mechanism 21, and an inner seat transport mechanism 23 that is vertically reciprocatingly mounted on the inner seat vertical movement mechanism 22. The inner seat transport mechanism 23 includes an inner seat rotating component (rotating motor) and an inner seat electric clamp 24 connected below the inner seat rotating component. The inner seat electric clamp 24 is used to clamp the inner seat 102. The inner seat rotating component can rotate the inner seat electric clamp 24 around a vertical axis to rotate the incoming material 90 degrees. Multiple inner seat vertical movement mechanisms 22 are mounted on the inner seat moving mechanism 21, and each inner seat vertical movement mechanism 22 is equipped with an inner seat transport mechanism 23.

[0031] At this station, after the carrier rotates to this station, the inner seat installation assembly 2 repeats the action similar to the outer cover installation. The inner seat electric gripper 24 grabs the inner seat 102 from the inner seat conveying mechanism 20, and after translation and lifting, accurately places it inside the already placed outer cover 101.

[0032] See Figure 14 The spring installation assembly 3 includes a spring installation mechanism and a spring conveying mechanism 30; the spring conveying mechanism 30 is used to convey the spring 103; the spring installation mechanism is used to vertically insert the conveyed spring 103 into the axial hole of the inner seat 102 of the fixed carrier 150.

[0033] Specifically, the spring installation mechanism includes: a spring rotation mechanism 34, a spring moving mechanism 31, a spring vertical movement mechanism 32 that can be horizontally reciprocated and arranged on the spring moving mechanism 31, and a spring conveying mechanism 38 that can be vertically reciprocated and arranged on the spring vertical movement mechanism 32; wherein, the spring conveying mechanism 38 is provided with a spring electric clamp 33; the spring electric clamp 33 is used to clamp the spring 103.

[0034] The spring mounting assembly 3 features a unique structural design to accommodate the spring's easily deformable nature. It comprises a spring handling mechanism 38 (consisting of a spring moving mechanism 31, a spring vertical displacement mechanism 32, and a spring electric gripper 33) for grasping the spring, and a spring rotating mechanism 34. The spring rotating mechanism 34 comprises a rotating disk rotatable about a horizontal axis, with a spring insert rod 35 (with a diameter slightly smaller than the spring's inner diameter) fixed to its side. The rotating disk, located below the spring handling mechanism 3, can be rotated 90 degrees to switch the spring insert rod 35 between a horizontal receiving position and a vertical feeding position.

[0035] At this station, the spring rotating mechanism 34 is in the horizontal receiving position, and the spring in the spring vibrating plate's conveying slide is inserted into the inner rod 35. Subsequently, the spring-loaded inner rod 35 is rotated 90 degrees, moving it to a vertical feeding position. The spring electric gripper 33 grabs a spring 103 from the inner rod 35. The spring transport mechanism 38 then rises, translates, and finally descends as a whole, inserting the spring 103 into the axial hole of the inner seat 102.

[0036] See Figure 11 、 15, 16, 17, 18. The shaft installation mechanism includes a shaft moving mechanism 42, a shaft vertical movement mechanism 43 disposed horizontally and reciprocatingly on the shaft moving mechanism 42, a shaft transport mechanism 45 disposed vertically and reciprocatingly on the shaft vertical movement mechanism 43, and a hole-aligning rotation mechanism 48 located below the shaft transport mechanism 45. The shaft transport mechanism 45 has an electric shaft clamp at its lower end. The hole-aligning rotation mechanism 48 is used to rotate and align the pin hole 1041 on the shaft 104 with the pin hole 1011 on the housing 101 to facilitate the subsequent insertion of the pin 105. The pin hole 1041 on the shaft 104 is a through hole to facilitate the insertion of the pin 105.

[0037] The hole-aligning rotation mechanism 48 includes a hole-aligning support 483, a hole-aligning clamping unit 481, a hole-aligning rotation bracket 49, and an optical positioning part. The hole-aligning rotation bracket 49 can be driven to rotate around a vertical axis. The hole-aligning clamping unit 481 is arranged on the hole-aligning rotation bracket 49, and is provided with a hole-aligning clamping electric chuck 482. The hole-aligning support 483 is fixedly installed below the hole-aligning clamping electric chuck 482. The optical positioning part can detect the position of the pin hole of the shaft and control the hole-aligning clamping electric chuck 482 to clamp the shaft and rotate it so that the pin hole of the shaft rotates to the target position.

[0038] The upper end of the hole alignment support 483 is provided with a bearing slot 484; the bearing slot 484 is coaxially located directly below the hole alignment clamping electric chuck 482. The hole alignment rotating bracket 49 includes a plurality of circumferentially arranged hole alignment connecting posts 485 and a hole alignment bearing plate fixedly connected to the upper ends of the hole alignment connecting posts 485; the hole alignment clamping unit 481 is fixedly mounted on the hole alignment bearing plate.

[0039] Two shaft transporting mechanisms 45 are horizontally spaced apart and arranged on the shaft moving mechanism 42. One shaft transporting mechanism 45 is used to transport the shaft from the shaft conveying mechanism 40 to the hole-matching rotating mechanism 48; the other shaft transporting mechanism 45 is used to transport the shaft from the hole-matching rotating mechanism 48 to the fixed carrier 150. The hole-matching clamping electric chuck 482 releases the shaft after clamping the shaft by the other shaft transporting mechanism.

[0040] Among them, a light-through hole is provided on the hole-clamping electric chuck 482, and the light positioning part includes a light sensor (not shown) and a light emitter (not shown) that emits light toward the light-through hole. The light sensor and the light emitter can be fixed on the lower surface of the hole-clamping bearing plate or the hole-clamping connecting column 485, and their approximate positions can be respectively located on both sides of the hole-clamping electric chuck 482. The light emitter emits light, and the light sensor located on the other side of the hole-clamping electric chuck 482 senses the light. When the shaft 104 is located on the hole-clamping bearing seat 483, the height of the pin hole on the shaft 104 is the same as the height of the light position. When the hole-clamping electric chuck 482 rotates, the shaft 104 remains stationary, and the light sensor senses the light when the light passes through the pin hole. The controller of the optical positioning unit can control the hole clamping electric chuck 482 to clamp and fix the shaft 104, and rotate the pin hole 1041 of the shaft 104 to the target position until the other shaft transport mechanism clamps the shaft and then releases the shaft, to avoid premature release of the shaft 104 to cause loosening and displacement.

[0041] The pre-insertion punching mechanism 85 includes a first linear drive mechanism and a pre-insertion punching head 851 driven by the first linear drive mechanism to perform horizontal linear reciprocating punching; when the fixed carrier 150 rotates to the shaft installation position, the pre-insertion punching head 851 is horizontally facing the pre-insertion positioning rod 159.

[0042] Specifically, the shaft mounting assembly 4 includes two parallel shaft transport mechanisms 45, both mounted on a mechanism synchronization frame 44. Driven by the shaft movement mechanism 41 and the shaft vertical displacement mechanism 43, they can perform three-dimensional motion. The shaft mounting assembly 4 comprises a hole-aligning rotation mechanism 48 and a pre-insertion punch mechanism 85 fixed to the equipment mounting plate 8 as primary functional components. The hole-aligning rotation mechanism 48 includes a base, which supports a hole-aligning rotation bracket 49 via a plurality of hole-aligning connecting columns 485. The bracket 49 is provided with a hole-aligning clamping unit 481, which primarily comprises a hole-aligning clamping electric chuck 482 that rotates with the hole-aligning rotation bracket 49. A hole-aligning bearing seat 483 with a bearing slot 484 is coaxially located below the hole-aligning clamping electric chuck 482 for initially positioning the positioning shaft 104. The pre-insertion punch mechanism 85 is a horizontally mounted linear drive mechanism (such as a cylinder) with a pre-insertion punch head 851 at its end.

[0043] When picking up materials and aligning holes, the first shaft transporting mechanism 45 grabs the shaft 104 from the shaft conveying mechanism 40 and places it in the bearing slot 484 of the hole-aligning rotating mechanism 48. The hole-aligning clamping electric chuck 482 descends to clamp the shaft 104. The optical positioning part detects the current angle of the pin hole on the shaft 104 and feeds back to the control system to control the rotation of the hole-aligning clamping electric chuck 482 until the pin hole is corrected to the target position. During transportation and installation, the second shaft transporting mechanism 45 moves to the top of the hole-aligning rotating mechanism 48, grabs the shaft 104 with the corrected posture, and transports it to the top of the fixed carrier 150, then descends vertically to insert the shaft into the spring 103. During pre-insertion positioning, after the shaft 104 is properly placed, the pre-insertion punching mechanism 85 is started, and its punching head 851 pushes the pre-insertion positioning rod 159. The pre-inserted positioning rod 159 passes through the front wall hole 153 of the carrier, the pin hole 1011 of the outer cover 101 and the calibrated pin hole 1041 on the shaft 104, thereby achieving precise temporary locking of the outer cover and the shaft.

[0044] See Figure 10 、 19 The pin installation assembly includes: a pin conveying mechanism 50, a pin moving mechanism 51, a pin vertical moving mechanism 52 that can be horizontally reciprocated and arranged on the pin moving mechanism 51, and a pin transporting mechanism 53 that can be vertically reciprocated and arranged on the pin vertical moving mechanism 52; wherein, the pin transporting mechanism 53 is provided with a pin electric clamp; the pin electric clamp is used to clamp the pin 105.

[0045] The pin conveying mechanism 50 includes a pin vibrating plate, a conveying trough 505, a pin handling base 57 disposed at the end of the conveying trough 505, and a pin detection unit 55 for detecting pins. The pin handling base 57 has a pin placement trough 571 and pin retrieval troughs 572 located on either side of the pin placement trough 571. It can move horizontally perpendicular to the conveying trough 505 to switch between a pin receiving position and a pin feeding position. The pin retrieval trough 572 is located near the pin head. When the pin handling base 57 is in the pin receiving position, the pin placement trough 571 is located directly in front of the conveying trough 505 and is connected. When the pin handling base 57 is in the pin feeding position, the pin retrieval trough 572 is located directly below the pin electric clamp.

[0046] The pin positioning mechanism 86 includes a pin bracket 861, a first pressing drive mechanism 862 installed on the pin bracket 861, and a first pressing head 863 driven by the first pressing drive mechanism 862 to perform vertical linear reciprocating movement; when the fixed carrier 150 rotates to the pin installation position, the first pressing head 863 is vertically facing the shaft 104.

[0047] The moving part of the pin insertion assembly 5 is mainly composed of the pin moving mechanism 51, the pin vertical movement mechanism 52 and the pin transporting mechanism 53, and the end is the pin transporting electric clamp 54. The pin positioning mechanism 86 fixed to the equipment fixed plate 8 is a vertical drive mechanism with a first downward pressure head 863. During operation, the first downward pressure head 863 of the pin positioning mechanism 86 first descends and gently presses the top of the shaft 104 to prevent it from moving during pin insertion. The pin 105 transporting electric clamp 54 grabs a pin 105 from the material picking position of the pin conveying mechanism 50. Then, the clamp moves horizontally to the side of the fixed carrier 150, aligns the pin 105 with the free end of the pre-insertion positioning rod 159, and pushes it forward horizontally. The front end of the pin 105 smoothly pushes the pre-insertion positioning rod 159 partially out from the other end, completing the relative position replacement.

[0048] See Figure 20 、 21 The pin insertion assembly 6 includes a pin punching mechanism 61, which includes a second linear drive mechanism and a pin insertion punch head driven by the second linear drive mechanism to perform horizontal linear reciprocating punching; when the fixed carrier 150 rotates to the pin insertion position, the pin insertion punch head is horizontally facing the pin inserted by the pin installation mechanism.

[0049] The positioning mechanism 82 includes a positioning bracket 821, a second pressing drive mechanism 822 mounted on the positioning bracket 821, and a second pressing head driven by the second pressing drive mechanism 822 for vertical linear reciprocating motion. When the fixed carrier 150 rotates to the pin-positioning position, the second pressing head is vertically aligned with the shaft 104. The positioning mechanism 82 is similar to the pin-insertion positioning mechanism 86, and the overlapping details are not further described.

[0050] The pin insertion assembly 6 primarily comprises a horizontally mounted pin ejection mechanism 61 (e.g., a small pneumatic cylinder). Furthermore, a positioning mechanism 82, similar in structure to the pin insertion positioning mechanism 86, is installed on the fixed plate 8 at this station. During operation, when the carrier rotates to this position, the positioning mechanism 82 presses the shaft 104 downward to maintain its position. The pin ejection mechanism 61 activates quickly, delivering a short, forceful impact to the rear end of the inserted pin 105, ensuring full insertion, eliminating installation margin, and fully resetting the pre-insertion positioning rod 159.

[0051] See Figure 23 、 2425. The pin riveting assembly 7 includes a flanging mechanism 75, a lock body moving mechanism 71, a lock body vertical movement mechanism disposed horizontally and reciprocatably on the lock body moving mechanism 71, and a lock body transport mechanism 73 disposed vertically and reciprocatably on the lock body vertical movement mechanism. The lock body transport mechanism 73 includes a lock body rotating component (e.g., a rotary motor) and an electric lock body clamp 74 connected below the lock body rotating component. The electric lock body clamp 74 is used to clamp the outer cover of the rotary lock. The lock body rotating component can rotate the electric lock clamp 74 about a vertical axis to rotate the rotary lock 90 degrees before placing it into the flanging mechanism 75.

[0052] The flanging mechanism 75 includes a flanging carrier 755 and an impact mechanism 751 located on both sides of the flanging carrier 755; impact holes 756 are respectively provided on both sides of the flanging carrier 755; when the rotary lock is placed as a whole on the flanging carrier 755, the two ends of the pin are respectively facing the impact holes 756 on both sides; the impact mechanism 751 includes an impact driving mechanism and an impact rod 753 driven by the impact driving mechanism; the rod end of the impact rod 753 is provided with an impact head that can extend into the impact hole 756 to impact the pin to form a flanging.

[0053] The pin riveting assembly 7 also includes a finished product conveying mechanism 76 and a finished product conveying trough 78; the finished product conveying mechanism 76 and the lock body conveying mechanism 73 are jointly installed on the lock body vertical movement mechanism for synchronous movement; the finished product conveying mechanism 76 includes a finished product electric clamp 77 for clamping the shaft of the rotary lock; wherein, the lock body conveying mechanism 73 is used to rotate the rotary lock from the fixed carrier 150 and place it on the flanging carrier 755; the finished product conveying mechanism 76 is used to convey the rotary lock after flanging on the flanging carrier 755 to the finished product conveying trough 78.

[0054] The pin riveting assembly 7 is the core of the finished product process. It includes a lock body moving mechanism 71 for handling, a riveting and vertical shifting mechanism 72, a lock body transport mechanism 73 (with a lock body electric clamp 74), and a finished product transport mechanism 76 (with a finished product electric clamp 77). The core device is the flanging mechanism 75, which includes a flanging carrier 755 with grooves matching the shape of the twist lock. Impact holes 756 are opened on both sides of the carrier, and impact mechanisms 751 are located on the outer sides of the holes. Each impact mechanism 751 consists of an impact drive mechanism (such as a powerful cylinder) and an impact rod 753 that drives the impact movement.

[0055] For the pin riveting station, when the material is taken out and placed, the electric clamp 74 of the lock body descends, clamps the semi-finished rotary lock in the fixed carrier 150, then lifts and rotates 90 degrees, and accurately places it on the flanging carrier 755. At this time, the two ends of the pin 105 are facing the impact through holes 756 on both sides. When the flanging riveting is performed, the impact mechanism 751 on both sides is activated, and the impact rod 753 extends at high speed. Its front end strongly impacts the two ends of the pin, causing the material at the end of the pin to plastically deform and form a flanging, thereby permanently fixing the pin. When the finished product is unloaded, after the riveting is completed, the finished product electric clamp 77 of the finished product handling mechanism 76 descends, clamps the completed rotary lock product, takes it out of the flanging carrier 755, and places it in the finished product conveying trough 78, completing a complete automated assembly cycle.

[0056] Combine Figures 1 to 25 As shown, the working process of this embodiment is described in detail below to better understand the present invention.

[0057] After the equipment is started, the carrier rotating ring disk 9 rotates step by step, and the empty fixed carriers 150 are sequentially delivered to each station to complete the corresponding assembly task.

[0058] The cover installation station: The cover installation assembly 1 is responsible for loading the cover 101 onto the fixed carrier 150. The cover conveying mechanism 10 delivers the cover to the unloading position. The electric cover gripper 14 on the cover transport mechanism 13 descends to grasp the cover 101, which is then lifted by the cover vertical movement mechanism 12 and then translated by the cover movement mechanism 11 to directly above the fixed carrier 150. If necessary, the cover rotation unit can rotate the cover 101 90 degrees to adjust its position. Finally, it descends to precisely place the cover 101 into the carrier slot.

[0059] Inner seat installation station: This station is similar in structure and operation to the outer cover installation station. The inner seat electric gripper 24 of the inner seat installation assembly 2 picks up the material from the inner seat conveying mechanism 20 and, through translational and vertical motion, accurately places the inner seat 102 inside the already placed outer cover 101.

[0060] Spring installation station: see Figure 14 The design of the spring mounting assembly 3 is quite unique. The spring rotating mechanism 34 is positioned horizontally for receiving the material. The spring 103 within the spring vibrating plate's conveyor slide is inserted into the inner rod 35. Subsequently, the inner rod 35, carrying the spring 103, is rotated 90 degrees, moving it into a vertical feeding position. The spring electric gripper 33 then grabs a spring 103 from the inner rod 35. The spring transport mechanism 38 then rises, translates, and finally descends as a whole, inserting the spring 103 into the axial hole of the inner seat 102.

[0061] Shaft installation station: see Figure 11 、 15, 16, 17 and 18, specifically comprising the following steps: Axis alignment and handling: The axle mounting assembly 4 includes two axle handling mechanisms 45. The first handling mechanism grabs the axle 104 from the axle conveying mechanism 40 and places it on the axle alignment bearing seat 483 of the alignment rotation mechanism 48.

[0062] Hole-alignment rotation mechanism 48: This mechanism is central to ensuring pin hole alignment. Shaft 104 is placed within bearing slot 484 and clamped by an electric hole-alignment clamping chuck 482 above. An optical positioning unit detects the current angle of the pin hole on shaft 104 and controls the rotation of the hole-alignment rotation bracket 49 until the pin hole reaches the preset target position.

[0063] Pre-insertion Positioning: The second shaft transport mechanism grabs the corrected shaft 104 from the hole-aligning rotation mechanism 48 and inserts it vertically into the spring 103 of the fixed carrier 150. At this point, the pre-insertion punch mechanism 85 (e.g., a pneumatic or electric cylinder) fixed to the device's fixed plate 8 is activated, and its punch pushes the pre-insertion positioning rod 159 on the fixed carrier 150. The pre-insertion positioning rod 159 passes through the carrier front wall hole 153, the pin hole 1011 of the outer cover 101, and the pin hole 1041 of the shaft 104, thereby precisely and temporarily locking the outer cover 101 and shaft 104, preparing for the subsequent pin insertion.

[0064] Pin installation station: the carrier rotates to this station. The first downward pressure head of the pin positioning mechanism 86 fixed on the fixed plate 8 of the equipment is started, and the top of the shaft 104 is lightly pressed downward to prevent it from floating during the pin insertion process. The pin electric clamp 54 on the pin transporting mechanism 53 of the pin insertion assembly 5 takes the material from the pin conveying mechanism 50. Subsequently, the pin transporting mechanism 53 moves horizontally, aligns the pin 105 with the position of the pre-inserted positioning rod 159, and inserts it horizontally. During the insertion process, the front end of the pin 105 smoothly pushes the pre-inserted positioning rod 159 out from the other end, completing the "replacement" of the pre-inserted positioning rod 159 by the pin 105, thereby ensuring the precise implantation of the pin 105.

[0065] Pin positioning station: To ensure that the pin 105 is fully in place, the equipment is set up with this station. Figure 19 When the carrier rotates to this point, the second pressing head of the positioning mechanism 82 (similar in structure to the pin positioning mechanism 86) fixed to the equipment fixed plate 8 presses down on the fixed shaft 104. The pin ejection mechanism 61 (e.g., a small punching cylinder) of the pin insertion assembly 6 located outside the workstation is activated, and its positioning ejection head quickly impacts the tail of the pin 105, ensuring that the pin is fully inserted and fully resets the pre-insertion positioning rod 159.

[0066] Pin riveting station: This is the last step in the process of forming the final product. Figures 21 to 23 .

[0067] Material collection and placement: The lock body electric clamp 74 of the lock body transport mechanism 73 descends, clamps the semi-finished rotary lock product in the fixed carrier 150 (clamping the outer cover 101 part), then lifts it, rotates it 90 degrees, and places it on the flanging carrier 755 in the flanging mechanism 75 of the pin riveting assembly 7.

[0068] Flanging and riveting: Impact holes 756 are formed on both sides of the flange carrier 755. When the twist lock is in place, the ends of its pin 105 are exposed in these impact holes 756. The impact mechanisms 751 on both sides (driven by impact drive rods 753) are activated simultaneously or sequentially. The impact heads of the impact rods 753 extend into the holes and impact the ends of the pin, causing plastic deformation and forming flanges. This securely locks the pin to the shaft 104 and housing 101, completing the twist lock 100.

[0069] Finished product unloading: After riveting is completed, the finished product transport mechanism 76, which moves synchronously with the lock body transport mechanism 73, is started, and its finished product electric clamp 77 descends to clamp the shaft 104 part of the finished product, removes it from the flanging carrier 755, and places it in the finished product transport trough 78, completing a complete production cycle.

[0070] In this embodiment, the automated assembly equipment for twistlocks utilizes a rotating equipment platform 145 and multiple automated functional stations distributed around it, achieving fully automated assembly from component loading to finished product riveting. The coordinated operation of each station results in a tight cycle, significantly improving production efficiency. In particular, the provision of a pre-insertion positioning rod 159 and a pre-insertion ejection mechanism 85 cleverly solves the problem of precise positioning of the shaft and housing. The pin installation assembly 5 then performs replacement installation, ensuring accurate pin insertion. This automated assembly equipment for twistlocks achieves efficient, precise, and fully automated assembly of twistlocks.
