Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pulley processing, and in particular to a mute pulley processing device for door and window production. BACKGROUND

[0002] Under the design concept of modern architectural aesthetics and functionality, the importance of doors and windows as the bridge between indoor and outdoor space is self-evident. Sliding doors and windows have become a popular choice in residential, office and commercial facilities due to their smooth opening operation and efficient space utilization. However, traditional sliding doors and windows often produce noise during operation, which not only erodes the peaceful environment of living and working, but also may become a source of noise pollution in the surrounding environment. In order to solve this long-standing problem in the industry, mute pulley technology has emerged. It significantly improves the sliding smoothness of doors and windows through innovative design, while greatly reducing noise generation, providing users with a more comfortable user experience.

[0003] The mainstream mute pulley design on the current market generally adopts a two-section structure, that is, the pulley body and the mounting bracket are connected stably through a precise riveting process. This process requires the pulley to be precisely assembled with the help of professional riveting equipment during installation to ensure that the pulley and the bracket have sufficient firmness and excellent mute effect. However, over time, the pulley body may wear out due to long-term use and needs to be replaced. However, due to the irreversible riveting connection between the pulley body and the mounting bracket in the two-section structure, it is extremely difficult to replace the pulley body alone, and often requires the entire pulley to be replaced, which undoubtedly increases maintenance costs and resource waste.

[0004] In order to solve this pain point, the patent application file with publication number CN215255496U discloses a mute door and window pulley. This pulley adopts a revolutionary three-section design, which ingeniously separates the pulley, connecting block and fixed block, retaining the performance advantages of mute and stability, greatly improving the convenience of disassembly and replacement, and also having the shock absorption performance that traditional two-section designs do not have. This innovative design completely breaks the limitations of traditional two-section structures. However, due to its unique structure, there is currently no automatic assembly equipment designed specifically for this type of pulley on the market, and manual assembly operations are still relied on. This not only limits production efficiency and increases labor intensity, but also makes it difficult to meet the current fast-paced production line requirements, and there is an urgent need to develop more efficient and automated assembly solutions.

The initial position of the first group of fixed seats 30 on the fixed guide base 23 corresponds to the position of the assembly station of the connecting guide base 22.

[0068] Specifically, the structure of the present application is reasonable, the degree of automation is high, and the preset assembly steps can be precisely followed to accurately assemble the silent pulley. The feeding and discharging processes are automatically executed, and the traditional manual assembly operation is completely replaced. The present application not only greatly improves the production efficiency, but also greatly reduces the physical burden of the operator. It precisely meets the urgent needs of modern production lines for speed and efficiency. Through the application of the present application, the assembly process of the silent pulley will become extremely smooth and accurate, and the use effect will be significantly enhanced. It provides solid technical support and driving force for the intelligent and automated production of door and window manufacturing industry.

[0069] Specifically, the rack 1 in the application is stably installed on the ground as the basic support structure of the whole processing device, and the material guiding mechanism 2 is ingeniously installed on the rack 1. The material guiding mechanism 2 is innovatively constructed in a three-section modular manner and is specially configured with three groups of guide seats for accurately placing and positioning three key components of the silent pulley. The three groups of guide seats are sequentially arranged in the vertical direction on the surface of the rack 1 according to the needs of the assembly process, and the length of each group of guide seats is designed to be increasing. This ingenious layout not only ensures that the silent pulley can smoothly follow the predetermined assembly process, but also efficiently utilizes the vertical space, greatly reduces the ground occupation, and exhibits excellent use efficiency. Among them, the wheel body guide seat 21 is located at the uppermost position, and its length is moderate, which is used for accurately placing and positioning the pulley 10. The connecting guide seat 22 is located below the wheel body guide seat 21, and its length is slightly longer, which is used for accurately placing and positioning the connecting seat 20 and ensuring smooth docking with the upper pulley 10. The fixing guide seat 23 is located at the lowermost position, and its length is the longest, which is used for accurately placing and positioning the fixing seat 30 and ensuring smooth docking with the upper connecting seat 20. Among them, the wheel body guide seat 21 tightly abuts the top of the connecting guide seat 22, and the connecting guide seat 22 and the fixing guide seat 23 are kept at a certain interval, which provides space for the step-by-step assembly of the silent pulley. The application also sets a driving mechanism 3, which integrates efficient automatic assembly function to realize the rapid and accurate assembly of the silent pulley. The driving mechanism 3 includes a wheel body blanking assembly mechanism 31, a connecting blanking assembly mechanism 32, a double feeding mechanism 33, an electric drive mechanism 34 and a controller 35. Through the close cooperation of the controller 35 and the electric drive mechanism 34, the intelligent control of the processing process is realized, the processing precision and the stability of the product quality are ensured, the wheel body blanking assembly mechanism 31, the connecting blanking assembly mechanism 32 and the double feeding mechanism 33 are triggered in sequence by the electric drive mechanism 34, so that the above mechanisms can accurately follow the preset assembly steps to accurately assemble the three-section silent pulley, and automatically execute the feeding and discharging process, fully replacing the traditional manual assembly operation. The application not only greatly improves the production efficiency, but also greatly reduces the physical burden of the operators, accurately meets the urgent needs of modern production lines for speed and efficiency, and has good use effect. Among them, the wheel body blanking assembly mechanism 31 is located at the top of the rack 1 and accurately corresponds to the assembly station of the wheel body guide seat 21. The wheel body blanking assembly mechanism 31 is responsible for pushing the pulley 10 to the assembly station and pressing it down after reaching the assembly station, so that it moves to the inside of the connecting seat 20 below, realizing the automatic assembly of the pulley 10 and the connecting seat 20. The connecting blanking assembly mechanism 32 is also located at the top of the rack 1, but it is for the connecting seat 20. The connecting blanking assembly mechanism 32 is responsible for pushing the connecting seat 20 with the assembled pulley 10 to the assembly station and pressing it down after reaching the assembly station. The pulley 10 descends synchronously to drive the connecting seat 20 to descend and move to the inside of the fixing seat 30 below, realizing the automatic assembly of the connecting seat 20 and the fixing seat 30. The double feeding mechanism 33 is arranged on the connecting guide seat 22 and the fixing guide seat 23, respectively.The automatic feeding of the connecting seat 20 and the fixing seat 30 is realized, and the production efficiency is improved. The electric drive mechanism 34 is arranged in the rack 1, and provides power for all the automatic assembly mechanisms. Through precise motor control, the coordinated operation of each part is realized. The controller 35 is installed on the surface of the rack 1, is connected with the electric drive mechanism 34 through a bus system, is responsible for issuing instructions and intelligent control of the whole processing process.

[0070] In use, the pulleys 10, connecting seats 20 and fixing seats 30 are respectively placed on the wheel body guide seat 21, the connecting guide seat 22 and the fixing guide seat 23, and it is necessary to note that the first group of pulleys 10 is initially placed at the left side of one work station at the assembly station in the wheel body guide seat 21, the first group of connecting seats 20 is initially placed at the left side of one work station at the assembly station in the connecting guide seat 22 and corresponds to the position of the assembly station in the wheel body guide seat 21, and the first group of fixing seats 30 is initially placed in the fixing guide seat 23 and corresponds to the position of the assembly station in the connecting guide seat 22, in use, the electric drive mechanism 34 receives the instructions issued by the controller 35 and operates according to the instructions, the electric drive mechanism 34 first contacts the wheel body blanking assembly mechanism 31 and triggers the wheel body blanking assembly mechanism 31 to operate, the wheel body blanking assembly mechanism 31 pushes the first group of pulleys 10 on the wheel body guide seat 21 to the assembly station on the wheel body guide seat 21, when the first group of pulleys 10 reaches the assembly station, the wheel body blanking assembly mechanism 31 presses the pulley 10 downward to make it move downward and directly enter the first group of connecting seats 20 on the connecting guide seat 22, when the first group of pulleys 10 enters the first group of connecting seats 20 and is clamped with the first group of connecting seats 20, the electric drive mechanism 34 is separated from the wheel body blanking assembly mechanism 31, after the electric drive mechanism 34 is separated from the wheel body blanking assembly mechanism 31, the wheel body blanking assembly mechanism 31 is automatically reset, and the electric drive mechanism 34 continues to operate, then contacts the connecting blanking assembly mechanism 32 and triggers the connecting blanking assembly mechanism 32 to operate, the connecting blanking assembly mechanism 32 pushes the first group of connecting seats 20 with the first group of pulleys 10 assembled to the assembly station in the connecting guide seat 22, when the first group of connecting seats 20 reaches the assembly station, the connecting blanking assembly mechanism 32 presses the pulley 10 downward, the pulley 10 drives the connecting seat 20 downward and moves to the first group of fixing seats 30 below, when the first group of connecting seats 20 enters the first group of fixing seats 30, the electric drive mechanism 34 is separated from the connecting blanking assembly mechanism 32, after the electric drive mechanism 34 is separated from the connecting blanking assembly mechanism 32, the connecting blanking assembly mechanism 32 is automatically reset, and the electric drive mechanism 34 continues to operate and contacts the double blanking mechanism 33 and triggers the double blanking mechanism 33 to operate, the double blanking mechanism 33 pushes the connecting seat 20 and the fixing seat 30 to move one station in the direction of the assembly station respectively to realize automatic blanking, and during the feeding of the fixing seat 30, the three-section silent pulley assembled is automatically moved outward under the pushing of the second group of fixing seats 30 to realize automatic blanking, and it is necessary to note that the pulley 10 can realize automatic feeding due to the internal structure of the wheel body guide seat 21, so it is not necessary to set a feeding mechanism to push.

[0071] In one embodiment of the present application, as Figures 1-4As shown, the wheel body guide base 21 comprises a base body 211, a first L-shaped material groove 212, a first L-shaped guide groove 213 and a feeding guide frame 214. The base body 211 is fixedly connected to the surface of the rack 1. The first L-shaped material groove 212 is opened in the surface of the base body 211. The first L-shaped guide groove 213 is opened in the inner wall of the first L-shaped material groove 212. The feeding guide frame 214 is fixedly connected to the surface of the end of the base body 211 away from the wheel body discharging assembly mechanism 31 and corresponds to the position of the first L-shaped guide groove 213. The pulley 10 is located in the first L-shaped material groove 212. The limiting rod 101 on the pulley 10 is located in the first L-shaped guide groove 213 and is in sliding connection with the inner wall of the first L-shaped guide groove 213.

[0072] The first L-shaped guide groove 213 comprises a diagonal guide groove 2131, a variable-diameter guide groove 2132 and a vertical guide groove 2133. The diagonal guide groove 2131, the variable-diameter guide groove 2132 and the vertical guide groove 2133 are sequentially opened in the inner wall of the first L-shaped material groove 212 along the horizontal direction and are in communication. The opening angle of the diagonal guide groove 2131 is adapted to the installation angle of the feeding guide frame 214. The depth of the variable-diameter guide groove 2132 decreases in turn along the horizontal direction. The depth of the vertical guide groove 2133 is consistent with the depth dimension of the end of the variable-diameter guide groove 2132.

[0073] Specifically, the structure and connection relationship of the wheel body guide base 21 are further described. The wheel body guide base 21 is arranged to accurately place and position the pulley 10. In use, the pulley 10 is placed on the feeding guide frame 214. Since the feeding guide frame 214 and the inclined guide groove 2131 are both arranged to be inclined, under the action of gravity, the limiting rod 101 on the pulley 10 is attached to the inner wall of the feeding guide frame 214 and enters the inside of the inclined guide groove 2131 until it stops moving at the connection position of the inclined guide groove 2131 and the variable-diameter guide groove 2132. At this time, the pulley 10 moves to the right by one station and is positioned at the assembly station of the wheel body guide base 21. The reason for the stop of the pulley 10 is that the depth of the variable-diameter guide groove 2132 decreases along the horizontal direction. When the depth of the variable-diameter guide groove 2132 becomes shallow, it means that the inner wall of the variable-diameter guide groove 2132 will apply a certain extrusion force to the limiting rod 101. Under the action of the spring in the pulley 10, the limiting rod 101 will abut against the inner wall of the variable-diameter guide groove 2132, thereby achieving accurate positioning of the pulley 10. When the pulley 10 is moved to the assembly station by the wheel body unloading and assembling mechanism 31, the extrusion force from the inner wall of the variable-diameter guide groove 2132 will gradually increase. When the pulley 10 moves to the assembly station, although the bottom is not supported, under the abutting action of the limiting rod 101, it will hover at the assembly station. Then, the pulley 10 is pressed down by the wheel body unloading and assembling mechanism 31. After the pulley 10 is stressed, the limiting rod 101 will move downward along the inner wall of the vertical guide groove 2133 until it enters the inside of the connecting seat 20 and is fixed by the clamping hole arranged in the inner wall of the connecting seat 20. After the limiting rod 101 enters the inside of the clamping hole, one end thereof abuts against one end of the control rod 201. The above operation realizes assembly. When the first group of pulleys 10 is assembled, the second group of pulleys 10 is automatically moved to the connection position of the inclined guide groove 2131 and the variable-diameter guide groove 2132 under the action of gravity, thereby realizing automatic feeding.

[0074] In one embodiment of the present application, as Figures 5-7As shown, the connecting guide base 22 comprises an upper L-shaped guide base 221, a lower L-shaped guide base 222, a second L-shaped material groove 223, a second L-shaped guide groove 224, an elastic supporting plate 225 and a first ball 226. The upper L-shaped guide base 221 is fixedly connected to the surface of the rack 1 and abuttingly connected to the bottom of the base body 211. The lower L-shaped guide base 222 is fixedly connected to the surface of the rack 1 and located at one side of the bottom of the upper L-shaped guide base 221. The space inside the upper L-shaped guide base 221 and the lower L-shaped guide base 222 forms the second L-shaped material groove 223. The connecting base 20 is located inside the second L-shaped material groove 223 and slidingly connected to the inner wall of the second L-shaped material groove 223. The gap between the outer surfaces of the upper L-shaped guide base 221 and the lower L-shaped guide base 222 forms the second L-shaped guide groove 224. The control rod 201 on the connecting base 20 is located inside the second L-shaped guide groove 224 and slidingly connected to the inner wall of the second L-shaped guide groove 224. The inner wall of the upper L-shaped guide base 221 is provided with an opening groove 2211. The elastic supporting plate 225 is symmetrically and rotatably connected to the inner wall of the opening groove 2211 and provided with a reset torsion spring between the inner wall of the opening groove 2211. The first ball 226 is uniformly arranged on the inner wall of the lower L-shaped guide base 222. The connecting base 20 is slidingly connected to the surface of the first ball 226.

[0075] It should be noted that the end of the lower L-shaped guide base 222 beyond the upper L-shaped guide base 221 is provided with a slope in this example. When the connecting base 20 moves to this position, it can move a certain distance in the direction of the assembly station under the action of gravity.

[0076] Specifically, the structure and connection relationship of the connecting guide base 22 for accurately placing and positioning the connecting base 20 are further described. In use, the connecting base 20 is placed on the lower L-shaped guide base 222. Since the first ball 226 is arranged on the lower L-shaped guide base 222, and the end wall of the lower L-shaped guide base 222 beyond the upper L-shaped guide base 221 has a set slope, when the connecting base 20 is placed on the lower L-shaped guide base 222 and the friction is reduced by the first ball 226, the connecting base 20 will automatically move a set distance in the direction of the assembly station under the action of gravity. Since the first ball 226 is only installed in the set area, when the connecting base 20 is separated from the first ball 226, the connecting base 20 will stop moving under the action of friction. At this time, the connecting base 20 has entered the second L-shaped material groove 223, and the control rod 201 has also entered the set position of the second L-shaped guide groove 224, so as to contact the double feeding mechanism 33 and drive it to move in the direction of the assembly station. Through the cooperation of the double feeding mechanism 33 and the connecting feeding and assembly mechanism 32, the automatic feeding operation of the connecting base 20 is realized. When the connecting base 20 moves to the assembly station, the bottom is supported by the elastic supporting plate 225. When the connecting feeding and assembly mechanism 32 presses down the connecting base 20, the elastic supporting plate 225 will retract into the opening groove 2211 under the action of force. When the connecting feeding and assembly mechanism 32 is separated from the pulley 10 on the connecting base 20 and returns to the original position, the elastic supporting plate 225 will pop up again to prepare for the next support.

[0077] In one embodiment of the present application, as shown in Figures 8-9 The fixed guide base 23 includes an upper feeding convex guide base 231, a limiting guide base 232, a lower feeding convex guide base 233, and a second ball 234. The upper feeding convex guide base 231, the limiting guide base 232, and the lower feeding convex guide base 233 are sequentially and fixedly connected in the horizontal direction on the surface of the rack 1 and located on one side of the bottom of the lower L-shaped guide base 222. The upper feeding convex guide base 231, the limiting guide base 232, and the lower feeding convex guide base 233 are integrally formed. The fixed seat 30 is slidingly connected to the surface of the upper feeding convex guide base 231, the inner wall of the limiting guide base 232, and the surface of the lower feeding convex guide base 233, respectively. The second ball 234 is uniformly arranged on the surface of the upper feeding convex guide base 231 and the inner wall of the limiting guide base 232, respectively. The fixed seat 30 is slidingly connected to the surface of the second ball 234.

[0078] It should be noted that the top of the upper feeding convex guide base 231 in this example is arranged at a predetermined slope. The fixed seat 30 installed on the upper feeding convex guide base 231 can enter the limiting guide base 232 under the action of gravity after the friction is reduced by the second ball 234.

[0079] Specifically, the structure and connection relationship of the fixed guide base 23 are further described. The fixed guide base 23 is arranged for accurate placement and positioning of the fixed seat 30. In use, the fixed seat 30 is placed on the upper feeding convex guide base 231. Since the second ball 234 is arranged on the upper feeding convex guide base 231, and the upper feeding convex guide base 231 has a set slope at the top, the fixed seat 30 can enter the limiting guide base 232 under the action of gravity with little friction. Since the limiting guide base 232 is also provided with the second ball 234, when the double upper feeding mechanism 33 pushes the fixed seat 30 to move forward by one station, the friction can be greatly reduced, facilitating smooth pushing operation. The second ball 234 in the limiting guide base 232 is arranged at the left side of the assembly station of the connecting guide base 22. When the second ball 234 is separated from the fixed seat 30, the fixed seat 30 is accurately stopped and corresponds to the assembly station of the connecting guide base 22 under the action of friction, facilitating subsequent assembly of the connecting seat 20 to the fixed seat 30, and having good use effect.

[0080] In one embodiment of the present application, as shown in Figures 10-13 The wheel body unloading assembly mechanism 31 includes a first passive mechanism 350, a first linkage gear 360, and a single-frame pushing mechanism 370. The first passive mechanism 350 is arranged at the top of the rack 1 and corresponds to the position of the assembly station of the wheel body guide base 21. The first passive mechanism 350 is used for assembling the pulley 10 at the assembly station into the connecting seat 20 on the connecting guide base 22. One end of the first passive mechanism 350 penetrates into the rack 1 and is engaged with the first linkage gear 360 rotatingly connected to the inner wall of the rack 1. The single-frame pushing mechanism 370 is arranged on the seat body 211 and is in contact with the pulley 10. The single-frame pushing mechanism 370 is used for pushing the pulley 10 on the seat body 211 to the assembly station of the wheel body guide base 21. One end of the single-frame pushing mechanism 370 penetrates into the rack 1 and is connected with the first linkage gear 360.

[0081] The connecting blank assembling mechanism 32 comprises a second passive mechanism 321, a second linkage gear 322 and a double-frame pushing mechanism 323. The second passive mechanism 321 is arranged on the top of the frame 1 and located on one side of the first passive mechanism 350. The second passive mechanism 321 is used for assembling the connecting seat 20, which has been assembled with the pulley 10 and located at the assembling station, into the fixed seat 30 in the fixed guide seat 23. One end of the second passive mechanism 321 penetrates into the frame 1 and is engaged with the second linkage gear 322 rotatingly connected to the inner wall of the frame 1. The double-frame pushing mechanism 323 is arranged on the upper L-shaped guide seat 221 and is in contact with the control rod 201 in the connecting seat 20. The double-frame pushing mechanism 323 is used for pushing the connecting seat 20, which has been assembled with the pulley 10, to the assembling station of the connecting guide seat 22. One end of the double-frame pushing mechanism 323 penetrates into the frame 1 and is connected with the second linkage gear 322.

[0082] The first passive mechanism 350 and the second passive mechanism 321 are respectively connected with the electric drive mechanism 34.

[0083] Specifically, the structure and connection relationship of the wheel body blanking assembly mechanism 31 and the connection blanking assembly mechanism 32 are further described. The wheel body blanking assembly mechanism 31 is used to drive the pulley 10 to move to the assembly station and then press down the pulley 10 to make it enter the inside of the lower connection seat 20, thereby completing the assembly between the pulley 10 and the connection seat 20. The connection blanking assembly mechanism 32 is used to drive the connection seat 20 with the assembled pulley 10 to move to the assembly station and then press down the pulley 10 and synchronously drive the connection seat 20 to descend, so as to enter the inside of the lower fixed seat 30, thereby completing the assembly between the connection seat 20 and the fixed seat 30. Specifically, in use, the electric drive mechanism 34 first contacts the first passive mechanism 350 and triggers the first passive mechanism 350 to operate. The first passive mechanism 350 operates to synchronously drive the single-frame pushing mechanism 370 to operate through the first linkage gear 360. The single-frame pushing mechanism 370 pushes the pulley 10 to the assembly station. When the pulley 10 is pushed to the assembly station, the first passive mechanism 350 presses down the pulley 10. After the pulley 10 is forced to descend, it enters the inside of the lower connection seat 20, thereby completing the automatic assembly between the pulley 10 and the connection seat 20. After the pulley 10 and the connection seat 20 are assembled, the first passive mechanism 350 is separated from the electric drive mechanism 34. After the first passive mechanism 350 is separated from the electric drive mechanism 34, the first passive mechanism 350 is automatically reset. In the resetting process of the first passive mechanism 350, the single-frame pushing mechanism 370 is reset synchronously through the first linkage gear 360, so as to facilitate the movement of the pulley 10 to the assembly station in the next time. Then, the electric drive mechanism 34 continues to operate and contacts the second passive mechanism 321 and triggers the second passive mechanism 321 to operate. The second passive mechanism 321 operates to synchronously drive the double-frame pushing mechanism 323 to operate through the second linkage gear 322. The double-frame pushing mechanism 323 moves the connection seat 20 with the assembled pulley 10 to the assembly station. When the connection seat 20 is pushed to the assembly station, the second passive mechanism 321 presses down the pulley 10. The pulley 10 descends synchronously to drive the connection seat 20 to descend. After the connection seat 20 is forced to descend, it enters the inside of the lower fixed seat 30, thereby completing the automatic assembly between the connection seat 20 and the fixed seat 30. After the electric drive mechanism 34 is separated from the second passive mechanism 321, the second passive mechanism 321 is automatically reset. In the resetting process of the second passive mechanism 321, the double-frame pushing mechanism 323 is reset synchronously through the second linkage gear 322, so as to facilitate the movement of the connection seat 20 with the assembled pulley 10 to the assembly station in the next time.

The surface of the second special-shaped block 327 is in abutting connection with the surface of the second roller 326. The second special-shaped block 327 corresponds to the position of the second linkage gear 322 and is connected through the second one-way transmission device 328.

[0088] The second limiting guide groove 3214 has the same structure as the first limiting guide groove 381. The first limiting guide groove 381 comprises a slope section 3811 and a horizontal section 3812. In the initial state, the first ball 379 is located in the slope section 3811.

[0089] The first one-way transmission device 375 and the second one-way transmission device 328 are the same in structure and transmission direction.

[0090] It should be noted that the bottom of the lifting pressure seat 353 is provided with an arc-shaped groove matched with the outer dimensions of the pulley 10.

[0091] It can be understood that all the special-shaped blocks in the present application are 6-shaped.

[0092] Specifically, the structure and connection relationship of the first passive mechanism 350, the second passive mechanism 321, the single-frame pushing mechanism 370 and the double-frame pushing mechanism 323 are further described. In use, the electric drive mechanism 34 operates according to the instruction. The electric drive mechanism 34 first contacts the triangular transmission block 356 in the first passive mechanism 350, extrudes the triangular transmission block 356 to move downward, and compresses the first spring 354. The downward movement of the triangular transmission block 356 synchronously drives the fixed vertical shaft 351, the connecting plate 352, the lifting pressure seat 353 and the convex shaft 355 to move downward. The downward movement of the convex shaft 355 cooperates with the spiral segment in the spiral guide groove 358 to synchronously drive the rotating drum 357 and the synchronous gear 359 to rotate. The rotation of the synchronous gear 359 synchronously drives the first linkage gear 360 to rotate in reverse. The rotation of the first linkage gear 360 synchronously drives the first special-shaped block 374 to rotate in reverse through the first one-way transmission device 375. The rotation of the first special-shaped block 374 extrudes the first roller 373 to move to one side. The movement of the first roller 373 synchronously drives the first drive rod 371 to move and compresses the second spring 372. The movement of the first drive rod 371 synchronously drives the single support 376 to move. The movement of the single support 376 synchronously drives the first lifting rod 377 to move. In the initial state, the first lifting rod 377 is located at the top of the second set of pulleys 10 on the left side of the assembly station. The movement of the first lifting rod 377 synchronously drives the first ball 379 and the drive seat 3771 to move. The first ball 379 moves along the inner wall of the first limiting guide groove 381 to one side of the assembly station. During the movement, it is extruded by the inner wall of the first limiting guide groove 381 and moves downward under the extrusion force. The downward movement of the first ball 379 synchronously drives the first lifting rod 377 and the drive seat 3771 to move downward and compresses the third spring 378. The downward movement of the first lifting rod 377 and the drive seat 3771 first moves obliquely from the top of the second set of pulleys 10 to between the second set of pulleys 10 and the first set of pulleys 10, and then moves horizontally. After the horizontally moving drive seat 3771 contacts the first set of pulleys 10, it synchronously drives the first set of pulleys 10 to move to the assembly station. When the drive seat 3771 moves to the maximum stroke, the pulley 10 is completely located at the assembly station, and the limiting rod 101 also moves to the connection between the variable-diameter guide groove 2132 and the vertical guide groove 2133. When the convex shaft 355 moves to the vertical segment in the spiral guide groove 358, the position of the drive seat 3771 remains unchanged. The fixed vertical shaft 351 continues to drive the connecting plate 352 and the lifting pressure seat 353 to move downward. When the lifting pressure seat 353 contacts the pulley 10, it drives the pulley 10 to move downward, and the limiting rod 101 also moves downward along the inner wall of the vertical guide groove 2133 until it enters the connecting seat 20 and is fixed with the clamping hole in the inner wall of the connecting seat 20. When the electric drive mechanism 34 separates from the triangular transmission block 356, the fixed vertical shaft 351, the connecting plate 352, the lifting pressure seat 353 and the convex shaft 355 are automatically reset under the elastic force of the second spring 372. The lifting pressure seat 353 is separated from the pulley 10 at the assembly station,When the convex shaft 355 moves from the vertical section to the inside of the spiral section, it drives the rotating drum 357 and the synchronous gear 359 to rotate, the synchronous gear 359 drives the first linkage gear 360 to rotate in the positive direction, the first linkage gear 360 and the first special-shaped block 374 are provided with the first one-way transmission device 375, so that the first linkage gear 360 cannot drive the first special-shaped block 374 to rotate, but the first special-shaped block 374 can still rotate in the positive direction with the first linkage gear 360 under the influence of the third spring 378, when the driving part of the first one-way transmission device 375 rotates in the positive direction, the driven part of the first one-way transmission device 375 always moves with the driving part and keeps meshing with the driving part under the influence of the elastic force of the third spring 378, the driven part drives the first special-shaped block 374 to rotate in the positive direction, after the first special-shaped block 374 rotates in the positive direction, the first driving rod 371, the first roller 373 and the single support 376 are automatically reset under the action of the second spring 372, the single support 376 drives the first lifting rod 377 and the first ball 379 to reset, and the first lifting rod 377 drives the driving seat 3771 to move above the second set of pulleys 10 on the left side of the assembly station during the resetting process, so as to facilitate the next pushing operation on the first set of pulleys 10 on the left side of the assembly station.

[0093] Since the first passive mechanism 350 and the second passive mechanism 321 have the same structure, the pushing and assembling operations of the connecting seat 20 are almost the same as those of the pulley 10, and the applicant will not make redundant description here, and only the working principle of the double-frame pushing mechanism 323 will be briefly described, the electric drive mechanism 34 is separated from the first passive mechanism 350 and contacts the second passive mechanism 321, the second passive mechanism 321 drives the double-frame pushing mechanism 323 to run through the second linkage gear 322, the second linkage gear 322 drives the second special-shaped block 327 to rotate through the second one-way transmission device 328, the second special-shaped block 327 rotates to synchronously extrude the second roller 326, the second driving rod 324 and the double support 329 to move to one side and compress the fourth spring 325, the double support 329 drives the second lifting rod 3210 and the second ball 3212 to move, the second ball 3212 moves in the second limiting guide groove 3214, under the influence of the extrusion force of the inner wall of the second limiting guide groove 3214, the second lifting rod 3210 first moves obliquely downward, moves to the left side of the control rod 201 of the connecting seat 20, and then moves horizontally, pushes the control rod 201 and the connecting seat 20 to move to the assembly station, when the connecting seat 20 moves to the assembly station, the elastic supporting plate 225 supports the bottom of the connecting seat 20, then the second passive mechanism 321 presses the pulley 10 on the connecting seat 20 and drives the connecting seat 20 to enter the fixed seat 30 in the fixed guide seat 23, and the assembly operation between the connecting seat 20 and the fixed seat 30 is completed.

[0094] In one embodiment of the application, as shown inFigure 10 、 Figures 15-16 As shown in FIG. 17, the double feeding mechanism 33 includes an upper pushing mechanism 331, a lower pushing mechanism 332, a transmission shaft 333 and a driving gear 334. The upper pushing mechanism 331 and the lower pushing mechanism 332 are respectively arranged at the top of the upper L-shaped guide base 221 and the limiting guide base 232. The transmission shaft 333 is rotatably connected to the inner wall of the rack 1. The top and bottom of the transmission shaft 333 are respectively connected to the upper pushing mechanism 331 and the lower pushing mechanism 332. The driving gear 334 is fixedly connected to the surface of the transmission shaft 333 and connected to the electric driving mechanism 34.

[0095] The upper pushing mechanism 331 is the same as the double-rack pushing mechanism 323 in structure and transmission direction.

[0096] The lower pushing mechanism 332 includes a double pushing rack 3321, a groove 3322, a pushing grab 3323, a sixth spring 3324, a third driving rod 3325, a seventh spring 3326, a third roller 3327, a third special-shaped block 3328 and a third one-way transmission device 3329. The double pushing rack 3321 is horizontally and slidingly connected to the top of the limiting guide base 232. A strip-shaped through groove 2321 is formed in the surface of the limiting guide base 232 corresponding to the position of the mounting hole 301 in the surface of the fixed base 30. The groove 3322 is formed in the surface of the double pushing rack 3321 corresponding to the position of the strip-shaped through groove 2321. The pushing grab 3323 is rotatably connected to the inner wall of the groove 3322 and fixedly connected with the sixth spring 3324 between the inner wall of the groove 3322. One end of the pushing grab 3323 penetrates into the inside of the mounting hole 301 through the strip-shaped through groove 2321. The third driving rod 3325 is rotatably connected to the inner wall of the rack 1 and fixedly connected with the seventh spring 3326 between the inner wall of the rack 1. One end of the third driving rod 3325 is rotatably connected with the third roller 3327. The other end of the third driving rod 3325 is fixedly connected with one end penetrating into the inside of the rack 1 of the double pushing rack 3321. The third special-shaped block 3328 is rotatably connected to the inner wall of the rack 1 and located at one side of the third roller 3327. The surface of the third special-shaped block 3328 is in abutting connection with the surface of the third roller 3327. The third special-shaped block 3328 is connected with the transmission shaft 333 through the third one-way transmission device 3329.

[0097] The second one-way transmission device 328, the third one-way transmission device 3329 and the first one-way transmission device 375 in the upper pushing mechanism 331 and the double-rack pushing mechanism 323 are the same in structure and transmission direction.

[0098] Specifically, the structure and connection relationship of the double feeding mechanism 33 are further described. The double feeding mechanism 33 is arranged on the connecting guide base 22 and the fixed guide base 23, respectively, to realize automatic feeding of the connecting base 20 and the fixed base 30, and improve production efficiency. Specifically, in use, the electric drive mechanism 34 drives the driving gear 334 to rotate, which synchronously drives the transmission shaft 333 to rotate, and the transmission shaft 333 drives the upward pushing mechanism 331 and the downward pushing mechanism 332 to operate, respectively. The upward pushing mechanism 331 is used to push the connecting base 20 forward by one station, and the downward pushing mechanism 332 is used to push the fixed base 30 forward by one station, so as to realize automatic feeding and automatic discharging of the assembled mute pulley.

[0099] The specific working principle is as follows: the transmission shaft 333 rotates to synchronously drive the second special-shaped block 327 to rotate through the second one-way transmission device 328 in the upward pushing mechanism 331. The second special-shaped block 327 rotates to synchronously extrude the second roller 326, the second driving rod 324 and the double bracket 329 to move to one side and compress the fourth spring 325. The double bracket 329 moves to synchronously drive the second lifting rod 3210 and the second ball 3212 to move. During the movement of the second ball 3212 in the inner wall of the second limiting guide groove 3214, the second ball 3212 is extruded by the inner wall of the second limiting guide groove 3214, and the second lifting rod 3210 is first inclined downward and then moves horizontally to push the connecting base 20 to move to the direction of the assembly station. The transmission shaft 333 rotates to drive the third special-shaped block 3328 to rotate through the third one-way transmission device 3329, and the third special-shaped block 3328 rotates to synchronously drive the double pushing bracket 3321, the third driving rod 3325 and the third roller 3327 to move to one side and compress the seventh spring 3326. During the movement of the double pushing bracket 3321, the pushing catch 3323 is synchronously driven to move. Since one end of the pushing catch 3323 penetrates into the installation port 301 through the strip-shaped through groove 2321, the movement of the pushing catch 3323 synchronously drives the fixed base 30 to move through the installation port 301, so as to realize the feeding operation of the fixed base 30. When the pushing catch 3323 retreats, it moves out of the installation port 301 and abuts against the surface of the fixed base 30. When it moves to the position of the next installation port 301, it automatically enters the installation port 301 under the elastic force of the sixth spring 3324, so as to drive the next fixed base 30 to move.

[0100] In one embodiment of the present application, as Figure 10 and Figure 17As shown, the electric drive mechanism 34 comprises a double-shaft motor 341, an encoder 342, a first reciprocating screw rod 343, a connecting shaft 344, a second reciprocating screw rod 345, a first drive sliding seat 346, a second drive sliding seat 347, and a drive gear rod 348. The double-shaft motor 341 is fixedly connected to the inner wall of the rack 1. The encoder 342 is fixedly connected to the surface of the double-shaft motor 341.

The first reciprocating screw rod 343 and the second reciprocating screw rod 345 are respectively rotationally connected to the inner wall of the rack 1 and located outside the double-shaft motor 341. One end of the double-shaft motor 341 is fixedly connected to one end of the first reciprocating screw rod 343. The other end of the double-shaft motor 341 is fixedly connected to one end of the second reciprocating screw rod 345 through the connecting shaft 344. The first drive sliding seat 346 is threadedly connected to the outer surface of the first reciprocating screw rod 343 and is horizontally slidingly connected to the inner wall of the rack 1. The first drive sliding seat 346 is slidingly connected to the surface of the triangular transmission block 356 in the first passive mechanism 350 and the second passive mechanism 321, respectively. The second drive sliding seat 347 is threadedly connected to the outer surface of the second reciprocating screw rod 345 and is horizontally slidingly connected to the inner wall of the rack 1. The drive gear rod 348 is fixedly connected to the surface of the second drive sliding seat 347 and is located on one side of the drive gear 334. The drive gear 334 is meshingly connected to the teeth on the surface of the drive gear rod 348.

[0101] Specifically, the structure and connection relationship of the electric drive mechanism 34 are further described. The double-shaft motor 341 and the encoder 342 operate according to instructions. The double-shaft motor 341 operates to drive the first reciprocating lead screw 343 and the connecting shaft 344 to rotate. The connecting shaft 344 rotates to drive the second reciprocating lead screw 345 to rotate. The first reciprocating lead screw 343 and the second reciprocating lead screw 345 rotate to drive the first drive sliding seat 346 and the second drive sliding seat 347 to move horizontally outward, respectively. During the outward movement of the first drive sliding seat 346, the first drive sliding seat 346 successively contacts the triangular transmission block 356 of the wheel body blank assembly mechanism 31 and the connecting blank assembly mechanism 32, and triggers the wheel body blank assembly mechanism 31 and the connecting blank assembly mechanism 32 to operate successively. The drive gear rod 348 on the second drive sliding seat 347 does not trigger the double blanking mechanism 33 to operate during the outward movement. When the first drive sliding seat 346 and the second drive sliding seat 347 respectively reach the maximum stroke at one end of the first reciprocating lead screw 343 and the second reciprocating lead screw 345, they will automatically reset. During the resetting process, the first drive sliding seat 346 does not trigger the wheel body blank assembly mechanism 31 and the connecting blank assembly mechanism 32 to operate, while the drive gear rod 348 on the second drive sliding seat 347 triggers the double blanking mechanism 33 to operate, thereby pushing the connecting seat 20 and the fixed seat 30 to automatically blank and driving the assembled silent pulley to automatically blank. The encoder 342 is used to detect the number of rotations of the double-shaft motor 341 in real time, and sends data to the controller 35. The controller 35 determines the positions of the first drive sliding seat 346 and the second drive sliding seat 347 according to the number of rotations.
