[0054] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0055] Please refer to Figures 1-4 This embodiment provides a chain retaining ring assembly device 100, which includes a workbench 110, a conveying mechanism 120, a retaining ring feeding mechanism 130, a retaining ring expansion mechanism 140, and a retaining ring assembly mechanism 150.

[0056] The workbench 110 is equipped with a slide rail 111 for the chain 200 to slide. The slide rail 111 extends along a first direction and is equipped with an installation point for installing the retaining ring onto the chain 200. The conveying mechanism 120, the retaining ring feeding mechanism 130, the retaining ring expansion mechanism 140, and the retaining ring assembly mechanism 150 are all connected to the workbench 110.

[0057] The conveying mechanism 120 is used to convey the chain 200 along the first direction so that the chain 200 passes sequentially through the mounting points on the slide rail 111; the retaining ring feeding mechanism 130 is used to convey the retaining ring toward the retaining ring expanding mechanism 140; the retaining ring expanding mechanism 140 is used to expand the received retaining ring; the retaining ring assembly mechanism 150 is used to transfer the expanded retaining ring and install it onto the pin 220 of the chain 200 at the mounting point.

[0058] It should be noted that this embodiment uses a ladder chain as an example for assembling the retaining ring. In other embodiments of this utility model, the assembled chain 200 can be other types of chains 200. Furthermore, arrow A in the figure points to the first direction, arrow B points to the second direction, and arrow C points to the third direction.

[0059] Please refer to Figures 1-4 The working principle of this chain retaining ring assembly device is as follows:

[0060] The chain retaining ring assembly device includes a workbench 110, a conveying mechanism 120, a retaining ring feeding mechanism 130, a retaining ring expansion mechanism 140, and a retaining ring assembly mechanism 150.

[0061] The workbench 110 is equipped with a slide rail 111 for sliding the ladder chain. The slide rail 111 extends along the first direction and is equipped with an installation point for installing the retaining ring to the ladder chain. The conveying mechanism 120, the retaining ring feeding mechanism 130, the retaining ring expansion mechanism 140 and the retaining ring assembly mechanism 150 are all connected to the workbench 110.

[0062] The conveying mechanism 120 is used to convey the ladder chain along the first direction so that the ladder chain passes through the installation points on the slide rail 111 in sequence. During the assembly of the retaining rings on the ladder chain, the ladder chain to be assembled can be conveyed through the conveying mechanism 120, and it can pass through the installation points section by section as it moves along the first direction. It should be noted that when the conveying mechanism 120 is configured, its function is to convey the ladder chain according to the assembly rhythm. That is, according to the assembly requirements of the retaining rings on the ladder chain, the conveying mechanism 120 can move one link of the ladder chain at a time when moving the ladder chain, and after a single movement, it will move to the next link in the same direction. The purpose of this setting is to ensure that each link of the ladder chain can pass through the installation points in sequence, pause briefly at the installation points to complete the installation of the retaining rings, and then move to the next link in the same direction to install the retaining rings.

[0063] The retaining ring feeding mechanism 130 is used to convey the retaining ring toward the retaining ring expansion mechanism 140; the retaining ring expansion mechanism 140 is used to expand the received retaining ring; the retaining ring assembly mechanism 150 is used to transfer the expanded retaining ring and install it onto the pin 220 of the ladder chain at the installation point; thus, with this arrangement, the retaining ring can be continuously fed into the retaining ring expansion mechanism 140 through the retaining ring feeding mechanism 130, and the retaining ring expansion mechanism 140 can expand the retaining ring by stretching it open by a certain amount, so that it can be subsequently transferred to the retaining ring assembly mechanism 150 and assembled onto the pin 220 on the ladder chain through the retaining ring assembly mechanism 150;

[0064] Therefore, as can be seen from the above, during the use of the chain retaining ring assembly device 100, the conveying mechanism 120 enables the ladder chain to be assembled with retaining rings to move continuously along the slide 111, and the movement is intermittent, with one chain link moving at a time. At the same time, the aforementioned retaining ring feeding mechanism 130 continuously feeds the retaining rings, the retaining ring expanding mechanism 140 continuously receives and expands the retaining rings, and the retaining ring assembly mechanism 150 can adapt to the movement of the ladder chain. Thus, when each chain link moves to the installation point, the retaining ring in the retaining ring expanding mechanism 140 can be transferred and assembled onto the pin 220 on the corresponding chain link of the ladder chain during the time it stays there.

[0065] In summary, through the above structural configuration, the conveying mechanism 120 can complete the conveying of the ladder chain, while the retaining ring feeding mechanism 130 continuously feeds the retaining rings, the retaining ring expansion mechanism 140 continuously receives and expands the retaining rings, and the retaining ring assembly mechanism 150 can adapt to the movement of the ladder chain to complete the retaining ring installation steps. Thus, the conveying action of the ladder chain, the feeding of the retaining rings, the expansion of the retaining rings, the transfer of the retaining rings, and the assembly of the retaining rings can be carried out in a step-by-step or synchronous manner. This allows the assembly of the retaining rings to be carried out continuously with the movement of the ladder chain, thereby improving the automated continuous assembly of the retaining rings, achieving efficient and precise retaining ring assembly, and improving the production quality and efficiency of the ladder chain.

[0066] Further, please refer to Figures 1-6 In this embodiment, as can be seen from the above, the function of the conveying mechanism 120 is to convey the ladder chain along the first direction, i.e., the extension direction of the slide 111. Moreover, when configuring the slide 111, the slide 111 has a shape adapted to the chain 200 being conveyed, so as to improve the smoothness and continuity of the conveying process. When configuring the implementation mechanism, the conveying mechanism 120 may include a first moving module 121, a second moving module 122, and a conveying chuck 123; the first moving module 121 is connected to the worktable 110, the second moving module 122 is connected to the first moving module 121, and the conveying chuck 123 is connected to the second moving module 122.

[0067] The second moving module 122 is used to drive the conveyor chuck 123 to move along the second direction, so that the conveyor chuck 123 engages with at least one sprocket 210 on the chain 200, and the second direction is perpendicular to the first direction; the first moving module 121 is used to drive the second moving module 122 and the conveyor chuck 123 to move along the first direction, and when the conveyor chuck 123 engages with the sprocket 210 on the chain 200, it drives the chain 200 to move relative to the slide rail 111.

[0068] Therefore, through the above structural arrangement, the position of the conveyor chuck 123 can be adjusted by setting the first moving module 121 and the second moving module 122. When the conveyor chuck 123 engages with one or more sprockets 210 on the ladder chain, the first moving module 121 drives the second moving module 122 and the conveyor chuck 123 to move along the first direction, thereby driving the ladder chain to move relative to the slide rail 111, and thus adjusting the position of the ladder chain relative to the slide rail 111. It should be noted that in this embodiment, when configuring the conveyor chuck 123, in order to improve its stability when driving the ladder chain, it is adopted to engage with two sprockets 210 simultaneously. Moreover, when the conveying mechanism 120 drives the ladder chain to move along the slide rail 111, the distance of its single movement is the distance of one chain link. In other embodiments of this utility model, it can also be other distances.

[0069] Based on this, please refer to Figures 1-6 The working steps of the conveying mechanism 120 are as follows:

[0070] When the initial position of the conveying mechanism 120 is when the conveying chuck 123 is not in contact with the sprocket 210, the pin 220 of one link of the ladder chain is in the installation point and has been installed, or at this time, after the ladder chain moves a distance of one link, the pin 220 of one link can be in the installation point.

[0071] Subsequently, the second moving module 122 drives the conveyor chuck 123 to engage with the sprocket 210 of the ladder chain. Then, the first moving module 121 drives the conveyor chuck 123 and the ladder chain to move a distance of one chain link and maintain that position.

[0072] After the retaining ring assembly mechanism 150 installs the retaining ring onto the pin 220, the second moving module 122 drives the conveyor chuck 123 to disengage from the sprocket 210, and then the first moving module 121 moves in the opposite direction to the distance of one chain link. That is, through the movement of the first moving module 121 and the second moving module 122, the reset of the conveyor chuck 123 in the first direction and the second direction is completed.

[0073] Repeat the above steps to complete the assembly of the retaining ring for the next link.

[0074] Please refer to Figures 1-6During the assembly of the retaining ring, the aforementioned conveying mechanism 120 ensures the accuracy and stability of the retaining ring's assembly position. Furthermore, to further improve the installation accuracy and stability, the chain retaining ring assembly device 100 also includes a positioning mechanism 160. The positioning mechanism 160 abuts against the chain 200 within the slide rail 111 to restrict its movement along the first direction. Moreover, the positioning mechanism 160 and the conveying mechanism 120 are positioned on both sides of the slide rail 111. This arrangement ensures that during retaining ring assembly, the conveying chuck 123 and the positioning mechanism 160 abut against the ladder chain from both sides, thereby improving the positional accuracy and stability during installation.

[0075] Specifically, when configuring the positioning mechanism 160, the positioning mechanism 160 includes a positioning seat 161, a third moving module 162, and a positioning chuck 163; the positioning seat 161 is connected to the worktable 110, the third moving module 162 is connected to the positioning seat 161, and is also connected to the positioning chuck 163; the third moving module 162 is used to drive the positioning chuck 163 to move along a second direction so as to abut against the sprocket 210 of the chain 200 at the installation point, and the second direction is perpendicular to the first direction.

[0076] After the ladder chain is conveyed to its position by the aforementioned conveying mechanism 120, the positioning chuck 163 can be driven to move by the third moving module 162, so that the conveying chuck 123 and the positioning chuck 163 can support the ladder chain on both sides, thereby improving the stability of the assembly process and thus improving the installation accuracy and quality.

[0077] Further, please refer to Figures 1-8 In this embodiment, when configuring the retaining ring feeding mechanism 130, the retaining ring feeding mechanism 130 includes a feeding frame 131, a first feeding plate 132, a conveyor belt 133, a detection unit 134, and a second feeding plate 135.

[0078] The unloading rack 131 is connected to the workbench 110. The first unloading tray 132, the conveyor belt 133 and the second unloading tray 135 are all connected to the unloading rack 131. The first unloading tray 132 is used to feed the retaining ring to the conveyor belt 133. The conveyor belt 133 is used to feed the received retaining ring toward the second unloading tray 135. The second unloading tray 135 is used to feed the retaining ring to the retaining ring expansion mechanism 140.

[0079] The detection unit 134 is connected to the conveyor belt 133 and is used to detect the retaining rings conveyed by the conveyor belt 133 from the first feed plate 132 to the second feed plate 135.

[0080] With the above-described structure, the retaining rings transferred from the outside can be received through the first unloading tray 132 and transported to the second unloading tray 135 via the conveyor belt 133. During the transfer of the retaining rings between the first and second unloading trays 135 via the aforementioned conveyor belt 133, they can be detected by the monitoring unit. The purpose of this unit is to perform quality inspection on the transported retaining rings. The detection method can be image detection, that is, the detection unit 134 can be configured as an image acquisition component and electrically connected to the detection and analysis system. Then, the quality of the retaining rings can be analyzed by analyzing the acquired images of the retaining rings, and the system can output a judgment on whether the retaining rings are qualified or unqualified. It should be noted that the configuration and working principle of the aforementioned detection unit 134 are the same as those in the prior art, so they will not be described again here.

[0081] As can be seen from the above, the quality of the retaining rings on the conveyor belt 133 can be detected by the detection unit 134. Based on this, in order to prevent the retaining rings that are judged to be unqualified from being assembled onto the ladder chain, the retaining ring feeding mechanism 130 also includes a pusher and a collection box connected to both sides of the conveyor belt 133. The pusher is used to push the retaining rings that are unqualified by the detection unit 134 on the conveyor belt 133 into the collection box for collection.

[0082] Specifically, the pusher is electrically connected to the detection unit 134 mentioned above, or to the control system of the chain retainer assembly device 100, so that when the retainer is found to be misaligned, it can be pushed into the collection box for collection, so as to prevent the unqualified retainer from being assembled onto the ladder chain and affecting the quality of the ladder chain.

[0083] Furthermore, as can be seen from the above, in order for the retaining ring to be assembled onto the pin 220, it needs to be expanded, that is, it is opened from the opening of the retaining ring so that it can be transferred and installed onto the pin 220. It should be noted that the principle of its expansion is to increase the size of the inner ring of the retaining ring, so that it can be easily fitted into the transfer structure in the retaining ring assembly mechanism 150, and can be easily fitted onto the pin 220, and after its expansion force disappears, it will engage with the pin 220.

[0084] For details, please refer to Figures 1-11 When configuring the retaining ring expansion mechanism 140, it may include an expansion seat 141, a guide rod 142, an expansion block 143, a fourth moving module 144, and a retaining block 145.

[0085] The expansion base 141 is provided with an expansion station, and the expansion station is provided with an expansion mold 146;

[0086] The guide rod 142 is connected to the expansion seat 141, with one end extending toward the expansion station and the other end extending toward the retaining ring feeding mechanism 130; the retaining ring output by the retaining ring feeding mechanism 130 is sleeved on the guide rod 142 and slides along the guide rod 142 into the expansion station.

[0087] The fourth moving module 144 is connected to the expansion seat 141 and is used to drive the expansion block 143 to move, so that the expansion block 143 abuts against the retaining ring or the expansion mold 146 located in the expansion station, and drives the retaining ring to move relative to the expansion mold 146, or drives the expansion mold 146 to move relative to the retaining ring, so that the opening of the retaining ring expands; the stop block 145 is connected to the expansion seat 141 and abuts against the retaining ring located in the expansion station, so as to restrict the movement of the retaining ring in the direction of moving away from the expansion station.

[0088] As can be seen from the above, when the guide rod 142 is configured, only a part is shown in the figure. Its function is to receive the retaining ring output by the second feed plate 135. When receiving the retaining ring, its structure can adjust and guide the position of the retaining ring so that the retaining ring can adjust its position during the process of being conveyed to the expansion station.

[0089] Then, the retaining ring, which is conveyed to the expansion station by the guide rod 142, can drive the expansion block 143 to move when the fourth moving module 144 is working. This causes the expansion block 143 to abut against the retaining ring or the expansion mold 146 located in the expansion station, and drives the retaining ring to move relative to the expansion mold 146, or drives the expansion mold 146 to move relative to the retaining ring, so that the opening of the retaining ring expands. That is, through the aforementioned structural arrangement, relative movement can occur between the retaining ring and the expansion mold 146 in the expansion station, thereby allowing the retaining ring to be expanded. In this embodiment, the fourth moving module 144 drives the expansion block 143 to move, so that the expansion block 143 abuts against the retaining ring located in the expansion station, and drives the retaining ring to move relative to the expansion mold 146, so that the opening of the retaining ring expands. Moreover, during the movement of the retaining ring, it can also abut against it through the stop block 145 to restrict the movement of the retaining ring in the direction of leaving the expansion station.

[0090] It should be noted that, in order to enable the retaining ring to expand when it moves relative to the expansion mold 146, the expansion mold 146 is provided with a flaring structure that matches the opening of the retaining ring, and the flaring structure gradually increases in size along the direction of movement of the retaining ring, thereby enabling the opening of the retaining ring to be opened.

[0091] Based on the above structure, please refer to Figures 1-12 The retaining ring assembly mechanism 150 includes a mounting bracket 151, a movable component 152, a pressing seat 153, a pressing rod 154, and a pressing head 155.

[0092] Mounting bracket 151 is connected to workbench 110, pressing seat 153 is movably connected to mounting bracket 151 in at least two directions via movable component 152; pressing rod 154 is connected to pressing seat 153, pressing head 155 is movably connected to pressing rod 154, and a portion of pressing head 155 extends out of pressing rod 154.

[0093] The movable component 152 is used to drive the pressing seat 153 to move relative to the mounting bracket 151, so that the part of the pressing head 155 extending out of the pressing rod 154 moves into the expansion position of the expansion seat 141 and passes through the retaining ring. After the retaining ring is separated from the expansion mold 146, it is clamped in the pressing head 155.

[0094] The movable component 152 is also used to drive the pressing seat 153 to move relative to the mounting bracket 151, so that the pressing head 155 moves above the chain 200 at the mounting point and abuts against the pin 220, and then drives the pressing rod 154 to move toward the chain 200, and causes the retaining ring to disengage from the pressing head 155 and engage with the pin 220.

[0095] Therefore, through the above structural arrangement, during the assembly of the retaining ring, the movable component 152 drives the pressing seat 153 to move, thereby causing the pressing rod 154 and pressing head 155 on the pressing seat 153 to change positions between the installation point and the expansion station. When it moves to the expansion station under the action of the movable module, its pressing head 155 can pass through the retaining ring, which is now the expanded retaining ring. After the pressing head 155 passes through the retaining ring, the fourth movable module 144 can drive the expansion mold 146 and the expansion block 143 to move in the opposite direction, so that the expansion mold 146 disengages from the expanded retaining ring, thereby causing the expansion mold 146 to align with the retaining ring. The expansion effect of the retaining ring disappears, allowing the retaining ring to be clamped in the pressure head 155. That is, after the pressure head 155 moves to the expansion station and is conveyed to the retaining ring, the expansion effect of the expansion mold 146 on the retaining ring can be eliminated by causing the retaining ring to disengage from the expansion mold 146, thereby allowing the retaining ring to be clamped in the pressure head 155. The aforementioned method is achieved by the fourth moving module 144 driving the expansion mold 146 and the expansion block 143 to move in opposite directions. In other embodiments of this utility model, the pressure head 155 can also drive the retaining ring to move under the action of the moving component 152, thereby causing the retaining ring to disengage from the expansion mold 146.

[0096] When the retaining ring is clamped in the pressure head 155, it can be driven by the movable component 152 to move to the position directly above the pin 220 of the corresponding link of the ladder chain at the installation point. At this time, the positioning mechanism 160 and the conveying mechanism 120 can position the ladder chain to ensure its positional stability, thereby improving the installation accuracy and quality of the retaining ring. When the retaining ring clamped in the pressure head 155 is released onto the pin 220, the movable component 152 drives the pressure rod 154 to move towards the chain 200. Since the pressure head 155 is supported by the pin 220, the movement of the pressure rod 154 will cause the pressure head 155 to extend into the pressure rod 154, thereby causing the pressure rod 154 to abut against the retaining ring. With the movement of the pressure rod 154, the retaining ring is pushed onto the pin 220 and engaged with the pin 220, thus completing the assembly of the retaining ring.

[0097] Based on the above, the function of the movable component 152 is to drive the pressing seat 153, the pressing rod 154, and the pressing head 155 to move, so as to complete the assembly of the retaining ring. Based on this, the movable component 152 includes a fifth moving module 156 and a sixth moving module 157. The fifth moving module 156 is connected to the mounting bracket 151 and the sixth moving module 157, and the pressing seat 153 is connected to the sixth moving module 157. The fifth moving module 156 is used to drive the sixth moving module 157 and the pressing seat 153 to move along the second direction, and the sixth moving module 157 is used to drive the pressing seat 153 to move along the third direction. The first direction, the second direction, and the third direction are perpendicular to each other, and the expansion station and the installation point are spaced apart along the second direction.

[0098] That is, with the initial position of the pressing seat 153 being far away from the installation point and the expansion station, the steps for assembling the retaining ring are as follows:

[0099] First, the fifth moving module 156 drives the sixth moving module 157 and the pressing seat 153 to move along the second direction to directly above the expansion station. Then, the sixth moving module 157 drives the pressing seat 153 to move along the third direction, that is, it drives the pressing head 155 to move to the expansion station and pass through the retaining ring.

[0100] After the retaining ring is clamped in the pressure head 155, the sixth moving module 157 drives the pressing seat 153 to move along the third direction to directly above the expansion station, and then the fifth moving module 156 drives the sixth moving module 157 and the pressing seat 153 to move along the second direction to directly above the installation point.

[0101] Then the sixth moving module 157 drives the pressing seat 153 to move in the third direction, that is, to move the pressing rod 154 and the pressing head 155 to directly above the installation point. Then, they move in the same direction, so that the pressing head 155 is supported by the pin 220, and continue to move in the same direction, so that the retaining ring is pushed onto the pin 220 through the relative movement between the pressing rod 154 and the pressing head 155, thus completing the installation.

[0102] Reset;

[0103] Repeat the steps above.

[0104] After the aforementioned retaining ring is assembled, in order to inspect its assembly quality, the chain retaining ring assembly device 100 also includes an inspection mechanism 170. The inspection mechanism 170 is used to inspect the installation status of the retaining ring on the chain 200. It should be noted that the inspection method of the inspection mechanism 170 can be an image inspection method. That is, the inspection mechanism 170 can be configured as an image acquisition component and electrically connected to the inspection and analysis system. Then, the installation quality of the retaining ring can be analyzed by analyzing the acquired installation image of the retaining ring, and a judgment on whether the installation status of the retaining ring is qualified or unqualified can be output. It should be noted that the setting and working principle of the aforementioned inspection mechanism 170 are the same as those of the prior art, so they will not be described again here.

[0105] It should also be noted that the above-mentioned first moving module 121, second moving module 122, third moving module 162, fourth moving module 144, fifth moving module 156, sixth moving module 157 and pusher can be any of the linear slide rail motion mechanism, cylinder moving mechanism and lead screw motion mechanism in the prior art, and their structure will not be described in detail here.

[0106] In addition, the chain retaining ring assembly device 100 also includes a housing 180, a control system, and a display system. All of the above structures are housed within the housing 180. The control system and display system can both utilize existing technologies. The control system is used to electrically connect with the various mechanisms and units mentioned above to achieve control, continuity, and automation of the retaining ring assembly, and can receive various detection data to collect and analyze the overall working data. The display system includes real-time data display, abnormal situation display, and alarm. It can display data and issue alarms through a display screen and alarm lights. The specific structural setup will not be described in detail here.

[0107] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
