Description

Technical Field

[0001] This utility model relates to the field of decelerator production equipment, specifically to an automatic blade feeding and assembly device for decelerators. Background Technology

[0002] In daily life, the toilet, as an important part of sanitary facilities, receives much attention regarding its user experience. When people close the toilet, the toilet seat and lid fall rapidly in free fall, colliding with the toilet bowl and producing a loud bang. This impact also subjects both the toilet seat and the toilet itself to considerable force, significantly reducing their lifespan. Therefore, toilets often require a damper to cushion the fall of the toilet seat. The production process of a soft-close device involves the assembly of multiple parts, with the assembly of the housing and blades being a crucial step. The blades, as an important component of the soft-close device, are small in shape and have a unique structure, which presents numerous challenges for material loading and assembly.

[0003] In traditional production methods, due to the small size of the blades, it is difficult for robotic arms to accurately position and grasp them if they are laid flat on the feeding track, conveyor belt, or material tray. During the grasping process, the robotic arm may experience material leakage, meaning it may fail to successfully grasp the blades or the grasp may be unstable, causing the blades to fall. This not only affects production efficiency but also increases the scrap rate and production costs. To avoid this situation, the industry currently commonly uses manual labor to vertically insert a large number of blades into a material tray, and then the robotic arm picks up the blades from the tray one by one and inserts them into the corresponding slots in the corresponding housings.

[0004] While this semi-automatic feeding and assembly method has solved the problem of robotic arms directly grabbing and laying blades to some extent, the process of manually inserting blades requires a lot of time and manpower. Moreover, the speed and accuracy of manual operation are affected by the skill level and fatigue of the operators, making it difficult to guarantee stable production efficiency and meet the needs of large-scale, high-efficiency production.

[0005] In order to improve the efficiency of loading and assembling the decelerator blades, it is necessary to develop an automatic loading and assembly device for the decelerator blades. Utility Model Content

The limiting plate drive component is mounted on the frame and is connected to the limiting plate in a transmission manner. The limiting plate drive component is used to drive the limiting plate to move toward or away from the receiving rod.

[0020] During blade assembly, the limiting plate abuts against the end of the blade outside the limiting hole to restrict the blade to be set vertically.

[0021] Furthermore, the aforementioned limiting hole, feeding channel, and blade have the same cross-sectional shape and size. The top of the discharge end of the feeding channel is provided with a clearance opening, which is used to allow the end of the blade located outside the limiting hole to rotate into or out of the feeding channel.

[0022] Furthermore, the aforementioned automatic blade feeding and assembly device for the decelerator also includes a position sensor. The limiting hole is a through hole. The number of position sensors is the same as the number of limiting holes and they are set one-to-one.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] This utility model provides an automatic feeding and assembly device for decelerator blades, which is used to solve the problem of how to improve the feeding and assembly efficiency of decelerator blades 61.

[0043] See Figure 1 and Figure 2 As shown, Figure 1 The figure shows a perspective view of the automatic blade feeding and assembly device for the decelerator in the embodiment. The automatic blade feeding and assembly device for the decelerator includes a frame 1, a feeding mechanism 2, a receiving rod 3, a rotary drive mechanism 4, and an assembly mechanism 5.

[0044] The feeding mechanism 2 is mounted on the frame 1 and includes a feeding channel 21 for continuously conveying the blades 61 one by one.

[0045] The receiving rod 3 has a limiting hole 31, which is used to insert one end of the blade 61 and limit the blade 61. The rotary drive mechanism 4 is fixedly or slidably mounted on the frame 1 and is connected to the receiving rod 3 for transmission. The rotary drive mechanism 4 is used to drive the receiving rod 3 to rotate toward or away from the feeding channel 21.

[0046] The assembly mechanism 5 is mounted on the frame 1 and is used to transfer the blade 61 on the receiving rod 3 and insert it into the slot 621 of the housing 62.

[0047] When the blade 61 is fed, the limiting hole 31 is connected to the feeding channel 21 and located on the extension line of the feeding channel 21 to receive the blade 61 output by the feeding channel 21. When the blade 61 is assembled, the limiting hole 31 and the blade 61 therein are arranged vertically, and the end of the blade 61 outside the limiting hole 31 faces upward so that the assembly mechanism 5 can grip it.

[0048] When using the automatic blade feeding and assembly device of the decelerator described above, firstly, the rotary drive mechanism 4 drives the receiving rod 3 to rotate towards the feeding channel 21, so that the limiting hole 31 aligns with the feeding channel 21. Simultaneously, the feeding mechanism 2 continuously feeds blades 61 one by one through the feeding channel 21, precisely inserting one end of the last blade 61 into the aligned limiting hole 31. Then, the rotary drive mechanism 4 drives the receiving rod 3 to rotate away from the feeding channel 21, so that the limiting hole 31 and the blades 61 therein are vertically aligned, with the end of the blade 61 outside the limiting hole 31 facing upwards. Finally, the assembly mechanism 5 grips the end of the blade 61 outside the limiting hole 31, pulls the blade 61 out of the limiting hole 31, and accurately transfers it into the slot 621 of the housing 62, completing the automated assembly of the blades 61. As can be seen, this utility model can realize the automated feeding and assembly of the decelerator blades 61. The entire feeding and assembly process does not require manual intervention, effectively avoiding the inefficiency and error problems caused by individual differences, fatigue and other factors in manual operation, significantly improving the feeding and assembly efficiency of the blades 61, thereby effectively improving the overall production efficiency of the decelerator. At the same time, it reduces labor costs and improves the accuracy and consistency of assembly.

[0049] The aforementioned feeding mechanism 2 may also include a feeding mechanism such as a mechanical vibratory feeder 22, the discharge end of which is connected to one end of the feeding channel 21, for continuously supplying blades 61 to the feeding channel 21.

[0050] The aforementioned rotary drive mechanism 4 can use existing rotary cylinders or rotary motors-belt / gear transmission assemblies, etc.

[0051] See Figure 1 As shown, in one embodiment of the feeding mechanism 2 and the receiving rod 3, there are at least two feeding channels 21. The number of limiting holes 31 is not less than the number of feeding channels 21, and the limiting holes 31 are spaced apart along the extension direction of the receiving rod 3. Each feeding channel 21 corresponds to one limiting hole 31, ensuring that each blade 61 of each feeding channel 21 has a corresponding limiting hole 31 to receive it. In this way, the arrangement of multiple feeding channels 21 and limiting holes 31 allows for the simultaneous feeding of multiple blades 61, further improving feeding efficiency, meeting the needs of large-scale production of decelerators, and improving the overall production rhythm of decelerators.

[0052] See Figure 1 and Figure 2 As shown, Figure 2 This is a partial structural diagram of the frame, feeding mechanism, receiving rod, and rotary drive mechanism in the embodiment. Based on the above embodiment, the automatic blade feeding and assembly device for the decelerator also includes a switching mechanism 7. The rotary drive mechanism 4 is slidably mounted on the frame 1, and the switching mechanism 7 is mounted on the frame 1 by means of screwing or welding, and is connected to the rotary drive mechanism 4 in a transmission manner. The switching mechanism 7 is used to drive the rotary drive mechanism 4 and the receiving rod 3 to move along the extension direction of the receiving rod 3. In this way, the switching mechanism 7 can flexibly switch the feeding channel 21 to correspond to different limiting holes 31. This feature allows a single feeding channel 21 to supply blades 61 to multiple limiting holes 31 in an orderly manner, further improving feeding efficiency and flexibility.

[0053] The aforementioned switching mechanism 7 can use existing linear drive mechanisms such as telescopic cylinders, stepper motor-lead screw and nut linear modules, or servo motor linear modules.

[0054] See Figure 1 , Figure 2 and Figure 3 As shown, Figure 3 This is a partial left view of the frame, feeding mechanism, receiving rod, and rotary drive mechanism in the embodiment. Based on any of the above embodiments, the automatic feeding and assembly device for the decelerator blades further includes a limiting mechanism 8, which is mounted on the frame 1 and located on one side of the receiving rod 3. During blade assembly, the limiting mechanism 8 restricts the blades 61 on the receiving rod 3 to be vertically positioned. Thus, the limiting mechanism 8 can limit the blades 61 during the assembly stage, ensuring that the blades 61 are in a vertical state, providing a good foundation for the subsequent assembly mechanism 5 to accurately grasp and insert the blades 61, improving assembly accuracy, and reducing assembly errors caused by blade 61 positional deviations.

[0055] See Figure 1 , Figure 2 and Figure 3As shown, in one embodiment of the limiting mechanism 8, the limiting mechanism 8 includes a limiting plate 81 and a limiting plate driving member 82. The limiting plate driving member 82 is mounted on the frame 1 by means of screwing or welding, and is connected to the limiting plate 81 in a transmission manner. The limiting plate driving member 82 is used to drive the limiting plate 81 to move towards or away from the receiving rod 3. During the assembly of the blade 61, the limiting plate 81 abuts against the end of the blade 61 located outside the limiting hole 31 to restrict the blade 61 to a vertical position. Thus, the limiting plate driving member 82 drives the limiting plate 81 to move, and the abutment between the limiting plate 81 and the blade 61 achieves precise positioning of the blade 61. This limiting structure is simple and reliable, and can quickly and effectively ensure the vertical state of the blade 61, improving the stability and accuracy of the assembly process.

[0056] The aforementioned limit plate drive component 82 can use existing linear drive mechanisms such as telescopic cylinders and telescopic poles, and its output end is connected to the limit plate 81 by means of screwing or welding.

[0057] See Figure 1 As shown, based on any of the above embodiments, the cross-sectional shape and size of the limiting hole 31, the feeding channel 21, and the blade 61 are all the same. A clearance opening (not shown in the figure) is provided at the top of the discharge end of the feeding channel 21. The clearance opening allows the end of the blade 61 located outside the limiting hole 31 to rotate into or out of the feeding channel 21. Thus, the limiting hole 31, the feeding channel 21, and the blade 61 are all the same in shape and size, ensuring the smoothness of the blade 61 during conveying and receiving, and reducing problems such as jamming and wear caused by size mismatch. Furthermore, the clearance opening design allows the blade 61 to rotate with the receiving rod 3, preventing interference between the end of the blade 61 located outside the limiting hole 31 and the feeding channel 21.

[0058] See Figure 1 , Figure 2 and Figure 3 As shown, based on any of the above embodiments, the automatic blade feeding and assembly device for the decelerator further includes a position sensor 9. The limiting hole 31 is a through hole. The number of position sensors 9 is the same as the number of limiting holes 31, and they are arranged in a one-to-one correspondence. The position sensor 9 is installed on an open end face of the corresponding limiting hole 31 and is used to sense whether a blade 61 is inserted into the corresponding limiting hole 31. In this way, the position sensor 9 can accurately detect whether a blade 61 is inside the limiting hole 31, providing reliable signal feedback for subsequent assembly operations, avoiding the situation where a blade 61 is not inserted into the limiting hole 31, thus improving the reliability and stability of the entire automated production process and ensuring product quality.

[0059] The aforementioned position sensing device can be a position switch, proximity switch, or distance sensor, etc.

[0060] See Figure 1As shown, in one embodiment of the assembly mechanism 5, the assembly mechanism 5 includes a robot arm 51 and clamps 52. The number of clamps 52 is the same as the number of feeding channels 21, and they are arranged in a one-to-one correspondence. The clamps 52 are used to grip or release the blades 61. The robot arm 51 is mounted on the frame 1 by means of screwing or welding, and is connected to the clamps 52 in a transmission manner. The robot arm 51 is used to drive the clamps 52 to reciprocate between the receiving rod 3 and the housing fixture 63. Thus, the robot arm 51, in cooperation with the clamps 52, can simultaneously grasp and transfer several blades 61, transferring the blades 61 from the receiving rod 3 to the housing fixture 63 for insertion assembly, greatly improving assembly efficiency and ensuring the positional accuracy of the assembly.

[0061] The aforementioned robotic arm 51 can be an existing robotic arm 51, and the clamp 52 can be an existing clamping cylinder, which can be installed on the output end of the robotic arm 51 by means of screwing or welding.

[0062] See Figure 1 As shown, based on the above embodiment, the assembly mechanism 5 further includes a pressure block 53 and a pressure block drive member 54. The pressure block drive member 54 is mounted on the output end of the robot arm 51 by means of screwing or welding, and is connected to the pressure block 53 in a transmission manner. The pressure block drive member 54 is used to drive the pressure block 53 to move toward or away from the blade 61 on the housing fixture 63. Thus, after the blade 61 is inserted into the slot 621 of the housing 62, the pressure block drive member 54 drives the pressure block 53 to move toward the blade 61, which can further press the blade 61 to ensure that the blade 61 is inserted in place, thereby further ensuring the assembly quality of the blade 61.

[0063] The aforementioned pressure block drive component 54 can use existing linear drive mechanisms such as telescopic cylinders and telescopic poles, and its output end is connected to the pressure block 53 by means of screwing or welding.
