Description

Technical Field

[0001] The invention relates to the technical field of annular part fastening, and in particular to an annular part feeding mechanism, an annular part fastening device and applications thereof. Background Art

[0002] In the field of ring-shaped parts manufacturing and assembly, the precise fastening of ring-shaped parts is an important step to achieve their functionality. For example, in the curtain manufacturing industry, curtain rings need to be firmly installed on both sides of the curtain through the fastening process to achieve the hanging and free movement of the curtain. The traditional fastening process of ring-shaped parts mostly relies on manual operation, including manually placing the ring-shaped parts, adjusting the position and completing the stamping. This operation process is not only inefficient and labor-intensive, but also difficult to meet the needs of efficient production.

[0003] With the continuous development of automation technology, belt-transmitted ring-jointing equipment has emerged, attempting to improve production efficiency through mechanized means. However, these devices have exposed the following problems during use: ring-jointed parts are prone to slipping or shifting during belt transmission due to unreasonable slideway design or insufficient friction, affecting the joint accuracy and stability of continuous operation; the belt transmission system is not only accompanied by high energy consumption, but also requires a large installation space, which is not conducive to promotion and application in the compact layout of production lines.

[0004] Therefore, the prior art needs to be further developed. Summary of the invention

[0005] The purpose of the present invention is to overcome the above-mentioned technical deficiencies and provide a ring-shaped part feeding mechanism, a ring-shaped part fastening device and its application, so as to solve the technical problems of low operating accuracy, high energy consumption and large space occupation in the process of ring-shaped part transmission and fastening in the related technology.

[0006] In order to achieve the above technical objectives, the present invention adopts the following technical solutions: a ring-shaped part feeding mechanism is provided, including a feeding device for storing ring-shaped parts and feeding the ring-shaped parts one by one, and a pushing device for pushing the ring-shaped parts supplied by the feeding device to the processing position one by one, wherein an activity space for the pushing device is reserved under the feeding device, and the ring-shaped parts stored in the feeding device move downward by gravity and enter the activity space one by one. When the ring-shaped part at the bottom of the feeding device moves to the activity space, the pushing device pushes the ring-shaped parts to the processing position.

[0007] Furthermore, the feeding device includes a feeding rod on which a ring is mounted, and the lower end of the feeding rod is arranged toward the activity space, so that the ring mounted on the feeding rod slides downward along the feeding rod under the action of gravity and enters the activity space one by one.

[0008] Furthermore, the feeding device includes a limiting mechanism arranged corresponding to the lower end of the feeding rod, and the limiting mechanism forms an activity space for the pushing device. Under the action of gravity, the annular parts on the feeding rod slide downward along the feeding rod, enter the limiting mechanism to queue up, and enter the activity space one by one.

[0009] Furthermore, the upper end of the feeding rod is suspended to realize the vertical setting of the feeding rod.

[0010] Furthermore, the limiting mechanism is a limiting frame arranged around the feeding rod, the lower end of the feeding rod is arranged in the limiting frame, and the bottom of the limiting frame forms an activity space for the pushing device. The annular parts on the feeding rod slide downward along the feeding rod under the action of gravity and enter the limiting frame, and enter the activity space one by one after being stacked in the limiting frame.

[0011] Furthermore, the pushing device includes a pushing plate and a power device for driving the pushing plate to move. Driven by the power device, the pushing plate reciprocates in the activity space below the feeding device, pushing the annular parts entering the activity space one by one to the processing position.

[0012] Furthermore, it also includes a material receiving mechanism arranged at the corresponding processing position, the material receiving mechanism includes a material receiving seat, a material trough for carrying the annular part is arranged on the material receiving seat, and an air hole connected to an external air pump is arranged on the trough surface. After the annular part is pushed to the material receiving seat by the pushing device, the annular part is adsorbed in the material trough of the material receiving seat by suction through the air hole.

[0013] Furthermore, the air holes are arranged in a plurality, and the plurality of air holes are arranged around the center of the trough, wherein the air holes are respectively distributed in the pushing direction of the pushing device and perpendicular to the pushing direction.

[0014] A ring-shaped member fastening device comprises the ring-shaped member feeding mechanism as described above.

[0015] The invention discloses an application of a ring-shaped fastening device, and an application of the ring-shaped fastening device in a curtain ring fastening device.

[0016] Beneficial effects: 1. The present invention uses gravity to achieve the natural downward movement of the annular parts through the feeding device, and cooperates with the limiting mechanism and the pushing device to complete the feeding and transmission of the annular parts one by one, avoiding the slipping or deviation problems caused by unreasonable slideway design or insufficient friction in the traditional belt transmission method, thereby improving the transmission stability and positioning accuracy of the annular parts.

[0017] 2. The present invention adopts the method of gravity transmission combined with a pushing device, which does not need to rely on a complex belt transmission system, significantly reduces the energy consumption during the operation of the equipment, and is in line with the concept of green manufacturing.

[0018] 3. Compared with the traditional belt transmission system which requires a larger installation space, the present invention reduces the space occupied by the overall equipment through the compact layout of the feeding device and the pushing device, and is more suitable for promotion and application in production lines, especially in working environments with limited space.

[0019] 4. Through the gravity sliding of the ring parts along the feeding rod, the orderly queuing of the limit frames, and the precise pushing of the pushing device, the present invention realizes a high degree of automation of the ring part transmission and feeding process, reduces manual intervention, improves the overall operation efficiency, and meets the needs of large-scale production.

[0022] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0023] According to an embodiment of the present invention, a ring-shaped part feeding mechanism is provided, comprising a feeding device for storing ring-shaped parts and feeding the ring-shaped parts one by one, and a pushing device for pushing the ring-shaped parts supplied by the feeding device to the processing position one by one, wherein an activity space for the pushing device is reserved below the feeding device, and the ring-shaped parts stored in the feeding device move downward by gravity and enter the activity space one by one, and when the ring-shaped parts at the bottom of the feeding device move to the activity space, the pushing device pushes the ring-shaped parts to the processing position. Compared with the traditional ring-shaped part feeding method based on belt transmission, the feeding device of this embodiment is designed to move downward by gravity, so that the ring-shaped parts can slide naturally to the activity space, and queue up to enter the pushing device in sequence, avoiding the problems of slipping and offset caused by insufficient friction of the slideway or too smooth surface, thereby greatly improving the stability of the feeding and transmission of the ring-shaped parts. The feeding device and the pushing device are compactly designed, and the transportation of the ring-shaped parts is completed by gravity, which abandons the high demand for installation space of the traditional belt transmission system, makes the overall structure of the equipment more compact, can adapt to the installation and production requirements in a limited space, and significantly reduces the volume occupied by the equipment. Since the feeding process relies on gravity, a complex belt drive device is no longer required. Combined with the streamlined power transmission of the pushing device, the energy consumption of the equipment during operation is effectively reduced, which is in line with the concept of green manufacturing and energy conservation and emission reduction.

[0024] In the annular member feeding mechanism of the present embodiment, the feeding device includes a feeding rod on which the annular member is sleeved, and the lower end of the feeding rod is arranged toward the activity space, so that the annular member sleeved on the feeding rod slides downward along the feeding rod under the action of gravity and enters the activity space one by one. The annular member slides downward along the feeding rod under the action of gravity, so that the annular member can enter the activity space one by one, thereby realizing the automation and orderliness of the feeding process, and avoiding the jamming problem caused by the annular member sliding poorly or piling up.

[0025] In the annular member feeding mechanism of the present embodiment, the feeding device includes a limiting mechanism corresponding to the lower end of the feeding rod, and the limiting mechanism forms the activity space of the pushing device. The annular members on the feeding rod slide downward along the feeding rod under the action of gravity, enter the limiting mechanism to line up, and enter the activity space one by one. The upper end of the feeding rod is suspended to realize the vertical setting of the feeding rod. The limiting mechanism is a limiting frame arranged around the feeding rod, and the lower end of the feeding rod is arranged in the limiting frame. The bottom of the limiting frame forms the activity space of the pushing device. The annular members on the feeding rod slide downward along the feeding rod under the action of gravity, enter the limiting frame 1, and enter the activity space one by one after being stacked in the limiting frame.

[0026] In the ring-shaped part feeding mechanism of the present embodiment, the pushing device includes a pushing plate and a power device for driving the pushing plate to move. Driven by the power device, the pushing plate moves back and forth in the activity space below the feeding device, pushing the ring-shaped parts entering the activity space one by one to the processing position, thereby realizing the transmission of the ring-shaped parts.

[0027] In the annular part feeding mechanism of this embodiment, a material receiving mechanism is also included, which is arranged at a corresponding processing position. The material receiving mechanism includes a material receiving seat, which is provided with a material trough for carrying the annular part, and the trough surface is provided with air holes connected to an external air pump. After the annular part is pushed to the material receiving seat by the pushing device, air is sucked through the air holes to adsorb the annular part in the material trough of the material receiving seat. There are multiple air holes, which are arranged around the center of the material trough, wherein the air holes are respectively distributed in the pushing direction of the pushing device and perpendicular to the pushing direction.

[0028] The annular part feeding mechanism of the present invention is not only suitable for the precise feeding of various single annular parts, but also supports the coordinated conveying of more than two annular components that need to be tightly connected. Single annular parts such as rubber sealing rings, O-rings, rubber gaskets, etc., are widely used in sealing and buffering in the automotive, machinery, electronics and other industries. Multiple annular parts that need to be engaged include upper and lower rings of curtains, hooks, flanges, clamps, annular inductors, annular bracelets, necklaces, earrings, etc. The present invention has relatively broad structural requirements for annular parts, as long as they meet the "hollow ring shape". The annular part can be a completely closed ring, or it can be a partial ring with an opening or a gap.

[0029] See also Figures 1 to 5 The ring-shaped member feeding mechanism of this embodiment takes the conveying of the upper ring 8 as an example: See also Figure 1 and Figure 2 The feeding mechanism for conveying the upper ring includes a first feeding rod 111 suspended vertically, a first pushing plate 211, and a movable space 3 for the first pushing plate 211 reserved below the first feeding rod 111. A first limiting frame 1211 is provided at the lower end of the first feeding rod 111, and a limiting groove 31 is provided on the first limiting frame 1211. The upper ring 8 sliding down from the first feeding rod 111 is regulated and limited by the first limiting frame 1211, so that the first pushing plate 211 can be sent out one by one from the limiting groove 31. The first feeding rod 111 is arranged vertically, and the gravity sliding method replaces the traditional belt transmission system, which greatly reduces the floor space and energy consumption of the equipment. The design of the limiting groove 31 ensures that the upper ring 8 can be sent out one by one and accurately, avoids mutual interference or accumulation between components, and effectively controls the entry into the processing position 4.

[0030] See also Figure 1 , Figure 2 and Figure 3The power device 22 for pushing the first push plate 211 to move is a cylinder, the first cylinder push rod 221 is connected to the first push plate 211, and the cylinder body is firmly installed on the support plate 241. In order to ensure that the first push plate 211 maintains a stable and accurate running track during the horizontal movement, a slide groove 242 is provided on the support plate 241, and a first support plate 245 is installed at intervals below the support plate 241. The first push plate 211 is connected to the first slide rail 244 and the first slider 243 installed on the first support plate 245 through the slide groove 242. The first slider 243 slides along the first slide rail 244, and combined with the guiding effect of the slide groove 242, a dual positioning and support is formed to ensure that the first push plate 211 will not tilt, shake or deviate when it moves back and forth horizontally under the drive of the cylinder push rod.

[0031] See also Figure 2 A clamping hole 2111 is provided on the first pushing plate 211, and the clamping hole 2111 runs through the first pushing plate 211, so that the upper ring 8 sliding down from the first feeding rod 111 can fall into the clamping hole 2111; with the horizontal movement of the first pushing plate 211, the clamping hole 2111 carries the upper ring 8 to the material receiving mechanism 5, and is transmitted to the processing position 4 by the material receiving mechanism 5.

[0032] See also Figure 3 and Figure 4 , the lower end of the first feeding rod 111 is located in the first limiting frame 1211, and the distance H1 between its end and the first pushing plate 211 is greater than the thickness T1 of the upper ring 8. In this way, it can be ensured that the upper ring 8 is not stuck on the first feeding rod 111, so that it can slide into the mesh hole 2111 of the first pushing plate 211. This design not only makes the feeding process smoother, but also avoids the phenomenon of stuck or incomplete sliding of the workpiece to be processed due to too small space, and ensures the accurate delivery of the workpiece to be processed. The opening depth D1 of the limiting groove 31 in the first limiting frame 1211 satisfies: D1=(1~1.5)*T1. The range of the opening depth D1 is set to 1~1.5 times the thickness T1 of the workpiece to be processed, which can prevent more than two workpieces to be processed from moving out of the limiting groove during the transmission process, and avoid the phenomenon of stuck and unsmooth feeding due to the limiting groove being too shallow, thereby optimizing the feeding accuracy and efficiency. The setting of the first limit frame 1211 can effectively regularize and limit the workpieces to be processed. When the upper ring 8 slides off the first feeding rod 111, it will be guided into the limit groove 31 one by one after passing through the first limit frame 1211, thereby avoiding the stacking or confusion of the workpieces to be processed during the delivery process. This structure effectively guarantees the stable delivery of the workpieces to be processed, ensuring that each workpiece to be processed can be delivered in a predetermined order and with precision, thereby improving the stability and consistency of production.

[0033] See also Figure 3 and Figure 4, the height H2 of the first limiting frame 1211 satisfies: 2*T1 < H1 < H2, where H1 is the distance between the first feeding rod 111 and the first pushing plate 211 (it can also be the distance from the end of the first feeding rod 111 to the bottom of the first limiting frame 1211. Since the first pushing plate 211 carries the upper ring and clips the upper ring into the card hole 2111, the distance between the first pushing plate 211 and the bottom of the first limiting frame 1211 only needs to leave enough clearance for movement. Therefore, the height of the clearance is ignored here), and H2 is the height of the first limiting frame 1211. The distance H1 between the first feeding rod 111 and the first pushing plate 211 should be greater than the thickness of two upper rings 8 to ensure that at least one annular part can smoothly fall onto the first pushing plate 211, guaranteeing the continuity of the material conveying process and preventing the conveying from being interrupted due to the jamming of the workpieces to be processed. The first limiting frame 1211 adopts a cubic structure, and its internal width is slightly larger than the outer diameter of the workpiece to be processed, thus providing free space for the sliding material and avoiding excessive contact or friction with the inner wall of the frame. By setting H2 > H1, it is ensured that the workpieces to be processed that slide from the first feeding rod 111 and are not sent out by the conveying plate can be orderly temporarily restricted within the first limiting frame 1211. This design effectively avoids the disorder phenomenon of the workpieces to be processed during the sliding process. The reasonable relationship between H1 and H2 ensures that the workpieces to be processed arranged in a vertical stack can be smoothly conveyed one by one. The setting of 2*T1 < H1 < H2 can not only ensure that the workpieces to be processed that are not sent out by the pushing plate can be orderly temporarily restricted within the first limiting frame 1211; being greater than the thickness of 2 upper rings avoids the distance between the first feeding rod 111 and the first pushing plate 211 from being too small, thus avoiding material jamming and ensuring that the workpieces to be processed can only be conveyed one by one. The design of H2 appropriately reserves the internal space of the limiting frame, enabling the workpieces to be processed arranged in a vertical stack to be orderly sent out one by one without excessive material retention due to the too high limiting frame. During the whole process, the friction between the workpieces to be processed and the frame or the support rod is reduced, avoiding the abnormal accumulation or sliding of the material, thereby improving the smoothness and accuracy of the material transmission. This spacing design avoids unnecessary friction or irregular material flow, thereby improving the reliability of the system.

[0034] Refer to Figure 5, the upper ring receiving mechanism of this embodiment adopts negative pressure adsorption to realize the operation of grabbing the upper ring 8. The receiving mechanism 5 includes a receiving seat 51, a first material trough 521 for accommodating the workpiece to be processed, and a first air hole 531 for sucking gas from the outside. The receiving seat 51 is provided with a first suction cup 511, and the first suction cup 511 includes a suction cup cover 5111 and an adsorption plate 5114. The suction cup cover 5111 and the adsorption plate 5114 are tightly connected, and the first air hole 531 and the first material trough 521 are both arranged on the first adsorption plate 5114. The shape of the first material trough 521 matches the structure of the upper ring 8, so as to realize close fitting adsorption. A first negative pressure chamber 5113 is arranged inside the suction cup cover 5111, and a plurality of air extraction holes 5112 are arranged at intervals on the cover body, which are connected to the suction cup cover 5111 through the air pipe connected to the negative pressure equipment via the air pipe connecting hole 5115. When working, the negative pressure device extracts the gas in the first negative pressure chamber 5113 through the air pipe, and the external gas enters through the first air hole 531, thereby forming a stable negative pressure area at the adsorption plate 5114, realizing the adsorption function of the upper ring 8.

[0035] See also Figure 5 , the upper ring receiving mechanism of this embodiment is used in combination with the stamping assembly 7. The stamping cylinder 71 causes the cylinder push rod to extend and retract to drive the receiving seat 51 to move to another component for stamping and buckling. In order to avoid mechanical interference or collision between the retraction action of the first push plate 211 and the downward movement of the stamping assembly 7 after the first suction cup 511 absorbs the upper ring 8, a avoidance groove 5211 is specially designed on the side of the adsorption plate 5114 close to the first push plate 211. The position and shape of the avoidance groove 5211 are adapted to the contour of the first push plate 211, thereby ensuring that the first push plate 211 can pass smoothly during the retraction process without affecting the normal operation of the stamping assembly 7. After the first suction cup 511 successfully absorbs the upper ring 8, the first cylinder push rod 221 drives the first push plate 211 to retract synchronously, and at the same time, the stamping assembly 7 moves downward in the vertical direction to complete the subsequent stamping operation of the upper ring 8. The reasonable design of the avoidance groove 5211 ensures that the two sets of actions can be carried out synchronously and efficiently without interference, further improving the working efficiency of the equipment and achieving high-efficiency buckling operation. The avoidance groove 5211 effectively eliminates the possibility of interference between the first push plate 211 and the punch assembly 7 in relative motion, protecting the operating safety of key components.

[0036] See also Figure 1 and Figure 3 A first protective cover 23 is provided on the first support plate 245 to prevent dust from being applied to the feeding mechanism of the upper ring and to protect the operators. A plurality of first covers 231 are provided on the first protective cover 23. The first covers 231 can be opened to observe the internal conditions in time.

[0037] See also Figures 6 to 9The ring-shaped member feeding mechanism of this embodiment takes the conveying of the lower ring 9 as an example: See also Figure 6 The feeding mechanism for conveying the lower ring includes a second feeding rod 112 suspended vertically, a second pushing plate 212, and a limiting gap 32 of the second pushing plate 212 reserved below the second feeding rod 112. A second limiting frame 1212 is provided at the lower end of the second feeding rod 112, and a support block 261 is installed at the lower end of the second limiting frame 1212. The support block 261 is arranged near the processing position 4 to support and guide the extension of the second pushing plate 212, thereby forming a dual positioning and support for the second pushing plate 212. The movable space between the second limiting frame 1212 and the support block 261 forms a limiting gap 32. The lower ring 9 that slides down from the second feeding rod 112 is regulated and limited by the second limiting frame 1212 and falls on the support block 261. The second pushing plate 212 pushes the lower ring 9 from one side to move on the support block 261, so that it is sent out one by one from the limiting gap 32. The lower ring 9 adopts the gravity sliding mode to replace the traditional belt transmission system, which greatly reduces the floor space and energy consumption of the equipment.

[0038] See also Figure 6 and Figure 7 The power device 22 for pushing the second push plate 212 to move horizontally is also a cylinder. The second cylinder push rod 222 is connected to the second push plate 212, and the cylinder body is installed on the second support plate 265. Similarly, in order to ensure that the second push plate 212 maintains a stable and accurate running track during the horizontal movement, the feeding mechanism of the lower ring is also provided with a stabilizing device. A slide rail fixing plate 264 is provided on the second support plate 265, and a second slide rail 263 is installed on the slide rail fixing plate 264. The second push plate 212 is connected to a second slider 262. The second cylinder push rod 222 drives the second push plate 212 to move horizontally and telescopically, and the second slider 262 slides on the second slide rail 263.

[0039] See also Figure 7 and Figure 8, the height D2 of the limit gap 32 satisfies: D2=(1~1.5)*T2, where T2 is the thickness of the lower ring, which prevents the second lower ring 9 from moving out of the limit gap 32. The height D2 of the limit gap effectively prevents multiple workpieces from being stacked or chaotically sliding out, ensuring that the conveyor plate can accurately and stably convey the workpieces to be processed one by one to the subsequent processing position. The lower end of the second feed rod 112 is located in the second limit frame 1212, and the distance H3 between the end of the second feed rod 112 and the support block 261 is greater than the thickness T2 of the two lower rings, thereby ensuring that one lower ring 9 smoothly falls to the support block 261 and is pushed by the second push plate 212, avoiding interruption of transmission due to material jamming. The height H4 of the second limit frame 1212 satisfies: 2*T2<H3<H4, so that the workpieces to be processed that slide off the second feed rod 112 and are not sent out by the conveyor plate can be stacked in order and temporarily limited in the second limit frame 1212. After the workpiece slides off the second feeding rod 112, the second limit frame 1212 is used to regulate the workpiece, ensuring that it enters the limit gap 32 one by one. According to the thickness of the ring, the reasonable control of D2, H3 and H4 avoids the material retention or abnormal accumulation caused by improper height setting, and further improves the operating reliability of the system. Similar to the structure of the first limit frame 1211, the width of the second limit frame 1212 is slightly larger than the outer diameter of the lower ring 9, so that the lower ring can slide into the frame to avoid friction.

[0040] See also Fig. 9 An arc-shaped groove 2121 is provided at the end of the second pushing plate 212. The lower ring 9 sliding down from the second feeding rod 112 falls onto the supporting block 261. As the second pushing plate 212 moves horizontally, it abuts against the arc-shaped groove 2121, thereby pushing the lower ring 9 to the processing position 4.

[0041] See also Figure 6 , Figure 7 and Fig. 9 , the lower ring receiving mechanism of this embodiment also adopts negative pressure adsorption to realize the grasping operation. A second suction cup 512, a second material trough 522 for accommodating the workpiece to be processed, and a second air hole 532 for sucking gas from the outside are arranged on the processing position 4, and a second negative pressure chamber 5121 is arranged in the second suction cup 512. The negative pressure device sucks the external gas through the second air hole 532 through the air pipe, and enters the second negative pressure chamber 5121 to form a stable negative pressure area outside the second suction cup 512, so as to realize the adsorption and positioning function of the lower ring 9. The shape of the second material trough 522 matches the structure of the lower ring 9 for better adsorption.

[0042] See also Fig. 9In this embodiment, the feeding mechanism for conveying the lower ring adopts four second air holes 532 arranged at intervals. The four second air holes are divided into two groups, each group includes two second air holes arranged oppositely, and each group of second air holes is connected to form a straight line, wherein the straight line formed by the first group of air holes is parallel to the horizontal moving direction of the second push plate 212 in the vertical direction, and the straight line formed by the second group of air holes is perpendicular to the horizontal moving direction of the second push plate 212, thereby ensuring that the lower ring 9 can be firmly adsorbed and accurately positioned. The four-point adsorption structure forms a mechanical constraint plane to ensure that the posture of the workpiece to be processed remains flat during the adsorption process. The first group of air holes provides a stable adsorption force consistent with the moving direction of the second push plate 212 to prevent the workpiece to be processed from being displaced; the second group of air holes provides an adsorption force perpendicular to the moving direction, which is used to limit the lateral displacement of the workpiece to be processed and enhance the lateral stability. This cross layout effectively distributes the adsorption force evenly around the workpiece to be processed, forming a symmetrical and stable adsorption state, and avoiding the warping or displacement of the workpiece to be processed due to single-point adsorption. The two-dimensional arrangement of the air holes realizes precise positioning on the plane of the workpiece to be processed.
