Description

Technical Field

[0001] This invention relates to an automated assembly device for connector safety handles, belonging to the technical field of automated equipment. Background Technology

[0002] Automation technology is widely used in industry, agriculture, military, scientific research, transportation, commerce, medicine, services, and households. Adopting automation technology not only liberates people from heavy physical labor, some mental labor, and harsh and dangerous working environments, but also expands human organ functions, greatly improves labor productivity, and enhances humanity's ability to understand and transform the world.

[0003] There is currently a demand for assembling a safety handle for connectors. This safety handle is used in high-current elbow connectors and achieves locking and unlocking between two connectors through pivot displacement, thereby meeting the safety requirements of stable locking and conduction and safe insertion and removal. The safety handle requires a locking key design.

[0004] The connector safety handle is as follows Figures 17 to 20 As shown, the device includes a handle body and a locking key assembly. The mounting end face of the handle body has a mating groove. The locking key assembly includes a first locking key, a second locking key for locking or releasing the first locking key, and two spring bodies. The mating groove has a first end groove for sliding mating with the first locking key and a second end groove for sliding mating with the second locking key. The end face of the first locking key facing the second locking key has two limiting holes for correspondingly mounting the spring bodies. The second end groove has a mating end face facing the first locking key, and the mating end face has two limiting protrusions for passing through the spring bodies.

[0005] In traditional assembly operations, the handle body, second locking key, and two springs are first assembled. Then, the first locking key slides to engage, allowing the springs to be positioned by limiting slots and limiting protrusions. During this assembly process, the free ends of the springs may shift, easily leading to improper installation and loss of the first locking key's reset function. Furthermore, in automated workstation designs, the handle body is assembled separately for the second locking key and the two springs. Therefore, a flipping station is required. Whether the second locking key or both springs are assembled first, flipping during this process can easily cause materials to fall out.

[0006] To address this issue, semi-automated production lines have emerged. These lines utilize automated fixtures to mount the handle body, which features a top-facing first end groove. The handle body sequentially passes through stations for assembling the second locking key and the spring body, with a locking mechanism applied after the second locking key assembly. It then undergoes manual pre-assembly at the first locking key assembly station, and is finally assembled using a pressing method. However, the manual intervention at these stations makes precise guidance difficult and impacts automated assembly efficiency. Furthermore, the handle body's mounting orientation affects the assembly of the second locking key, easily causing it to slip off during loading. This significantly impacts the overall assembly pass rate and efficiency. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of the prior art. In view of the problems that the traditional automated assembly sequence and station design have defects that prevent the spring body from being automatically assembled in place and that cause parts to fall off, affecting the assembly qualification rate and assembly efficiency, an automated assembly device for connector safety handles is proposed.

[0059] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0060] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in the present application can be combined with each other.

[0061] This invention provides an automated assembly device for connector safety handles, such as... Figures 17 to 20 As shown, the connector safety handle includes a handle body 100 and a locking key assembly 200. The mounting end face 110 of the handle body 100 has a mating groove 120. The locking key assembly 200 includes a first locking key 210, a second locking key 220 for locking or releasing the first locking key, and two spring bodies 230. The mating groove 120 has a first end groove 1201 for sliding mating with the first locking key and a second end groove 1202 for sliding mating with the second locking key. The end face of the first locking key 210 facing the second locking key has two limiting holes 2101 for correspondingly mounting the spring bodies. The second end groove 1202 has a mating end face facing the first locking key, and the mating end face has two limiting protrusions 12021 for passing through the spring bodies.

[0062] During assembly, the first locking key 210 is required to slide and engage in the first end groove 1201, and the second locking key 220 is required to slide and engage in the second end groove 1202. The two ends of the spring body 230 are respectively positioned relative to the limiting protrusion 12021 and the limiting hole groove 2101. At the same time, the second locking key 220 is located between the engaging groove 120 and the first locking key 210.

[0063] Traditional assembly processes often cause the second locking key 220 and the spring body 230 to fall off frequently. At the same time, the spring body 230 requires manual guidance assembly, which affects the product assembly qualification rate and assembly efficiency.

[0064] In this case, the design and construction of automated assembly equipment provided a relatively reasonable and scientific adjustment of processes and workstations, and the positional accuracy and guiding and straightening design met the requirements for fully automated and efficient operation.

[0065] Specifically, such as Figures 1 to 16 As shown, the automated assembly equipment includes a rotating tray 10 with several material loading positions 1, a first locking key loading station 2, a spring body assembly station 3, a handle body loading station 4, a second locking key assembly station 5, and an assembly station 6 arranged sequentially along the rotation direction of the rotating tray 10.

[0066] Among them, such as Figures 4 to 8 As shown, the loading position 1 includes a handle carrier 11 and a first locking key carrier 12 arranged at intervals. The handle carrier 11 includes a handle loading position 111 for limiting the mounting of the handle body and making the mounting end face of the handle body face the top. The first locking key carrier 12 includes a first locking key loading position 121 for mounting the first locking key and making the limiting hole groove of the first locking key face the top, and a first locking mechanism 122 for loosening or locking the first locking key. An assembly space 7 is left on the side of the first locking key loading position away from the first locking mechanism.

[0067] The first locking key feeding station 2 includes a first locking key feeding device 20 for automatically feeding the first locking key carrier.

[0068] The spring body assembly station 3 includes a spring body supply device 31 and a spring body assembly device 32 for picking up the spring bodies discharged from the spring body supply device and assembling them into the limiting hole groove to form a first assembly 300.

[0069] The handle body feeding station 4 includes a handle body supply device 40 for automatically feeding the handle body to the handle carrier.

[0070] The second locking key assembly station 5 includes a second locking key supply device 51 and a second locking key assembly device 52 for picking up the second locking keys discharged from the second locking key supply device and assembling them onto the second end slide to form a second assembly 400.

[0071] The assembly station 6 includes a free end straightening guide device 61 for guiding the free end of the spring body on the first locking key, and a snap-fit ​​assembly device 62 for picking up the second assembly and snapping it onto the first assembly. The snap-fit ​​assembly device 62 is provided with a locking and picking mechanism 620 for locking the handle body and the second locking key together.

[0072] Detailed implementation process and principle explanation:

[0073] The rotating tray 10 sequentially switches between stations along the path of the first locking key loading station 2, the spring body assembly station 3, the handle body loading station 4, the second locking key assembly station 5, and the assembly integration station 6.

[0074] At the first locking key feeding station 2, the first locking key feeding device 20 provides the first locking key and loads it onto the first locking key carrier 12. The first locking key carrier 121 is used for precise positioning, and the first locking mechanism 122 is used for stable locking.

[0075] Switch to spring body assembly station 3. At this time, the spring body supply device 31 continuously supplies spring bodies, and the spring body assembly device 32 picks up the spring body and assembles it into the limiting hole groove of the first locking key to form the first assembly 300. It should be noted that at this time, the spring body is stably mounted in the limiting hole groove due to its own weight.

[0076] After the first assembly 300 is assembled, it switches to the handle body loading station 4. At this time, the handle body supply device 40 loads the handle body onto the handle carrier 11 and runs it to the second locking key assembly station 5.

[0077] The second locking key supply device 51 supplies the second locking key, which is then picked up by the second locking key assembly device 52 and assembled onto the second end slide groove of the handle body to form the second assembly 400.

[0078] Finally, the system switches to assembly station 6. At this point, the free end straightening guide device 61 straightens and positions the free end of the spring body. The locking and picking mechanism 620 picks up the second assembly 400 and presses it onto the first assembly to complete the assembly. After assembly, the connector safety handle is formed as a whole. It can then be moved and unloaded as the locking and picking mechanism 620 moves. It should be noted that the second assembly 400 does not have a relative locking structure after assembly. Therefore, when the locking and picking mechanism 620 picks up the second assembly, it meets the relative locking structure requirements of the two structures, forming a complete assembly after pressing.

[0079] The spring body guides and straightens the assembly to meet the relative position accuracy requirements. It should be noted that during the guiding process, the free end straightening guide device 61 will retract after pressing to a certain stroke to complete the alignment. This will not interfere with the assembly displacement. The locking and picking mechanism 620 uses the assembly space 7 to realize the assembly connection.

[0080] In one specific embodiment, such as Figure 17 As shown, the handle body includes a U-shaped structure body, which includes two parallel pivot walls 101 and a mounting connection wall 102 connecting the two pivot walls 101. The mounting end face is set on the mounting connection wall.

[0081] like Figure 5 and Figure 6 As shown, the handle loading position 111 includes a bearing pile 1110 for limiting the mounting of the U-shaped structure body, and a handle locking mechanism 8 provided on the bearing pile 1110 for locking the handle body.

[0082] That is, the handle locking mechanism 8 is used to achieve stable locking of the handle body, so as to meet the assembly relative position accuracy requirements of the second locking key at the rear end.

[0083] In one specific embodiment, such as Figure 5 and Figure 6 As shown, the handle locking mechanism 8 includes two outwardly expanding locking ends 81 with relative opening and closing displacement located between two pivot walls, and a pressing locking plate 82 with linear displacement for pressing and locking the end faces of the two pivot walls.

[0084] Specifically, when locking the handle body, the two outwardly expanding locking ends 81 are relatively separated and abut against the inner wall of the pivot wall 101 to meet certain locking requirements, while the pressing locking plate 82 plays a secondary pressing locking role, thus meeting the relative assembly stability requirements and ensuring its positional accuracy.

[0085] It should be noted that because the main body of the handle needs to be rotated and assembled at assembly station 6, its positional accuracy requirements are very high, which is quite different from the requirements of traditional switching stations. The assembly of the second assembly at the rear end will be subject to pressure, while the rotation and picking positioning need to be accurate. Only in this way can the requirements for assembly stability and reliability be met.

[0086] In one specific embodiment, such as Figure 7 and Figure 8 As shown, the first locking key position 121 includes a limiting support groove 1210 for limiting and supporting the first locking key, and the first locking mechanism includes two clamping locking posts 1220 with relative opening and closing displacement.

[0087] This satisfies the precise positioning requirements of the first locking key, while also meeting the relative stability requirements of the first and second assemblies in the backend assembly, thus significantly improving the product assembly qualification rate.

[0088] In one specific embodiment, such as Figure 9 As shown, the first locking key feeding device 20 includes a first locking key feeding mechanism 21, a first locking key position calibration mechanism 22, and a first locking key turnover mechanism 23 with turnover displacement. The first locking key turnover mechanism is provided with a first locking key picking part.

[0089] Specifically, the first locking key feeding device 20 can adopt methods such as vibrating chamber feeding, conveyor belt conveying, and pallet supply. Any mechanism that needs to meet the automatic supply of the first locking key is within the protection scope of this case.

[0090] In this embodiment, a vibrating chamber feeding scheme is adopted, and a visual guidance mechanism is set on the top of the vibrating chamber to meet the identification requirements of the front and back sides. The first locking key position calibration mechanism 22 is a secondary calibration structure. That is, after the first locking key turnover mechanism 23 picks up the material, it is placed on the first locking key position calibration mechanism 22 for secondary calibration, and then picked up again before feeding. This can ensure its position accuracy.

[0091] like Figure 9 As shown, the first locking key position calibration mechanism 22 in this embodiment also has a flipping function, which satisfies the steering and correction requirements of the reverse material discharged from the vibration chamber.

[0092] The first locking key pickup unit is described below. Generally, a pickup mechanism such as a clamp or negative pressure pickup is used. In this embodiment, a clamp is used, which meets the requirements for transfer positioning accuracy.

[0093] In one specific embodiment, such as Figure 3 and Figure 10As shown, the spring body supply device 31 has a spring body feeding mechanism 310 at the discharge end. The spring body feeding mechanism includes a horizontal feeding platform 311. The horizontal feeding platform has two spring body horizontal loading slots 312 that are spaced apart and a pick-up clearance slot 313 that passes through any of the spring body horizontal loading slots.

[0094] The spring body assembly 32 includes a pickup platform 321 with linear circumferential displacement and lifting displacement, a steering seat 322 with rotational displacement on the pickup platform, and a spring body pickup part 323 on the steering seat.

[0095] Specifically, the spring body supply device 31 generally adopts a combination of a vibrating chamber and a direct vibration supply, and the spring body it discharges is generally supplied horizontally, making it difficult to achieve vertical supply.

[0096] Therefore, a horizontal feeding platform 311 was designed, and a horizontal loading groove 312 for the spring body was used to meet the requirements for docking with the direct vibration and the accuracy of the guiding position. The design of the pick-up clearance groove 313 can provide the picking space for the spring body picking part 323, thereby meeting its requirements for picking space and relative position accuracy.

[0097] When picking up the spring body, the spring body is horizontally clamped by the spring body picking unit 323, and the steering carrier 322 is used to turn the spring body to meet the requirements of adjusting the assembly direction.

[0098] In one specific embodiment, such as Figure 11 As shown, the handle body supply device 40 includes a handle body feeding mechanism 41 and a handle body turnover mechanism 42 for feeding and turnover. The handle body turnover mechanism is provided with a handle body picking-up part 420.

[0099] The handle body feeding device 40 generally uses a vibratory feeder, but a tray feeding can also be used. When a vibratory feeder is used, a visual guidance mechanism needs to be set up.

[0100] The handle body picking unit 420 is generally a clamp. The handle body turnover mechanism 42 picks up and loads materials, and a robotic arm can be used for turnover.

[0101] It should be noted that when a vibratory feeder is used, a reverse adjustment mechanism is added. That is, after picking up the material, it is placed on the reverse adjustment mechanism for reverse flipping and feeding, thus meeting the adjustment requirements of the gripping position and direction.

[0102] In one specific embodiment, such as Figure 12 As shown, the second locking key assembly station also includes a second locking key position calibration mechanism 53.

[0103] The second locking key supply device 51 includes a second locking key feeding mechanism and a second locking key picking visual guide mechanism disposed on the top of the second locking key feeding mechanism.

[0104] The second locking key assembly device 52 includes a second locking key turnover mechanism. The second locking key turnover mechanism has turnover displacement between the second locking key feeding mechanism and the second locking key position calibration mechanism, and between the second locking key position calibration mechanism and the handle carrier. The second locking key turnover mechanism is provided with a second locking key picking-up part 520.

[0105] Specifically, the second locking key feeding mechanism generally adopts a vibratory feeder, and the second locking key position calibration mechanism 53 is used for material flipping and hand changing and secondary position correction.

[0106] The second locking key pickup unit 520 is a pickup fixture, and all pickup mechanisms that ensure the high-precision position of the second locking key are within the protection scope of this case.

[0107] It should be noted that when assembling the second locking key, the material is transferred through the second locking key pick-up part 520 and then aligned and pressed. In a specific embodiment, the second locking key turnover mechanism also includes a smoothing end for switching displacement with the second locking key pick-up part 520. After the second locking key is pressed and assembled, a smoothing operation is performed through the smoothing end to meet the assembly relative accuracy requirements of the second assembly.

[0108] In one specific embodiment, such as Figures 12 to 16 As shown, the free end straightening guide device 61 includes a straightening slide 611 having a horizontal linear displacement toward the first locking key, and a second displacement slide 612 disposed on the straightening slide having a horizontal linear displacement toward the first locking key.

[0109] The straightening slide 611 is provided with two guide clamping parts 6110 with relative opening and closing displacement for clamping the spring body, and the second displacement slide 612 is provided with a straightening top rod 6120 located between the two guide clamping parts.

[0110] The second locking key is provided with a stepped structure, and the locking and picking mechanism 620 includes a first gripper and a second gripper with relative opening and closing displacement. The second gripper is provided with a contour positioning part 6200 that conforms to the stepped structure.

[0111] Detailed implementation process and principle explanation:

[0112] When the free end of the spring body is straightened and guided, the straightening slide 611 is displaced so that the free end is located between the two guide clamping parts 6110. At this time, the two guide clamping parts 6110 clamp the spring body. After clamping, the spring body is linearly displaced in the opposite direction to adjust the tilt direction of the spring body. Then, the second displacement slide 612 is displaced so that the straightening push rod 6120 pushes out the spring body. The correction position of the push-out is relatively fixed, thereby straightening the tilted and pulled spring body. At this time, the position of the free end of the spring body is fixed.

[0113] During the assembly process, the second assembly moves downwards. After the free end enters the limiting protrusion 12021, there is still a fitting gap. At this time, the free end straightening guide device 61 exits, and the second assembly continues to move downwards for assembly.

[0114] When transferring the second assembly, there is no tight fit between the handle body and the second locking key. At this time, the contour positioning part 6200 on the second gripper is used for positioning and clamping, so that the two are tightly fitted, while meeting the requirements for stable and precise positioning of the second assembly and ensuring the accuracy of the relative position of the assembly.

[0115] In one specific embodiment, the assembly station also includes a secondary pressing pile platform located on the turnover path of the locking and picking mechanism, and the secondary pressing pile platform is provided with a floating top rod for supporting the first locking key.

[0116] The attached diagram omits the illustration of the secondary pressing platform. After the first and second assemblies complete their relative pressing assembly, the connector mounting handle assembly is formed. This secondary pressing platform design enables secondary pressing assembly; the locking and picking mechanism 620 picks up the pressed connector mounting handle and moves it to the secondary pressing platform for secondary pressing, ensuring the product is properly assembled. Furthermore, the floating top rod is connected to a pressure sensor, which can also perform detection during the secondary pressing process. This makes the assembly operation more reliable and eliminates the need for cost-effective testing procedures and equipment.

[0117] The above description demonstrates that the automated assembly requirements for connector safety handles are met. By using spring-loaded alignment to maintain assembly precision, the product assembly pass rate is significantly improved. The process and station design, which involves assembling the first and second assemblies separately before merging them, accommodates the requirements for rotating workstations, resulting in smooth, efficient, stable, and reliable assembly operations. The compact equipment layout reduces space requirements. Precise positioning, stable locking, and relative positional accuracy protection for each workpiece ensure a high yield rate.

However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments.
