DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor also fall within the scope of the present application.

[0029] As Figures 1-8As shown, this embodiment discloses a fastener processing device, including a workbench 1, a conveyor plate 2 connected to a control module rotatably mounted on the workbench 1, a mold base 3 disposed on the periphery of the conveyor plate 2, and a fixing groove 4 with an opening on the outer edge of the mold base 3; it also includes a feeding station, an assembly pressing station, and a discharging station disposed on the workbench 1 and arranged sequentially along the rotation direction of the conveyor plate 2. The feeding station is connected to a first feeding mechanism 5, which can communicate with the fixing groove 4 through the opening on the mold base 3, and is used to feed a nut into the fixing groove 4; the assembly pressing station is provided with a pressing mechanism 7 that corresponds to the position of the fixing groove 4 and is located above the conveyor plate 2, and the pressing mechanism 7 is connected to a second feeding mechanism 6, which is used to feed a gasket into the fixing groove 4 and press it against the nut; the discharging station is provided with a discharging mechanism 8, which is used to discharge the material in the fixing groove 4 outward through the opening.

[0030] like Figure 1 As shown, it mainly consists of a workbench 1, a conveyor plate 2, a mold base 3, a feeding station, an assembly and pressing station, and a discharging station.

[0031] Workbench 1 serves as the foundational support platform for the entire device, upon which all other components are mounted. The conveyor plate 2 is rotatably mounted on workbench 1 via a rotating shaft, its rotation precisely controlled by a control module. The control module includes a controller and a servo motor connected to the controller. The servo motor is rotatably connected to the conveyor plate 2 via a rotating shaft, driving the conveyor plate 2 to rotate at a specific angle, thus conveying the material within the mold base 3. Multiple mold bases 3 are evenly distributed along the periphery of the conveyor plate 2. The mold bases 3 are fitted into slots on the edge of the conveyor plate 2, and each mold base 3 has a fixing groove 4 with an opening on its outer edge to accommodate and fix parts such as nuts and washers to be processed. Driven by the conveyor plate 2, the mold bases 3 sequentially pass through the feeding station, assembly and pressing station, and discharge station, thereby realizing the processing of fasteners.

[0032] The feeding station is positioned on the worktable 1 along the rotation direction of the conveyor plate 2. The feeding station is equipped with a first feeding mechanism 5, which consists of a vibratory feeder 51, a linear feeder, and a guide pipe 52. The vibratory feeder 51 generates vibrations at a specific frequency, arranging the nuts in an orderly manner and conveying them to the linear feeder. The linear feeder then pushes the nuts to the guide pipe 52 at a stable speed via its internal spiral track. The guide pipe 52 is precisely connected to the opening on the mold base 3, enabling accurate delivery of the nuts to the fixed slots 4 of the mold base 3, thus achieving precise nut placement. Each fixed slot 4 can only accommodate one nut; excess nuts are blocked at the opening of the worktable 1. Nuts will only continue to be conveyed forward after the next empty fixed slot 4 rotates to that position, effectively controlling the number of nuts conveyed.

[0033] When the first feeding mechanism 5 feeds the nut into the fixing groove 4 of the mold base 3, it is then conveyed to the assembly and pressing station, where it will be processed by the pressing mechanism 7.

[0034] like Figure 8 As shown, the pressing mechanism 7 includes a positioning rod assembly 71 located outside the conveyor plate 2 and at the opening of the fixed groove 4. The positioning rod assembly 71 is connected to a fourth telescopic cylinder 72, which can drive the positioning rod assembly 71 through the opening on the mold base 3 into the fixed groove 4. Specifically, the positioning rod assembly 71 consists of a set of hardened cylindrical rods, which are connected to the fourth telescopic cylinder 72 via a mounting plate. The fourth telescopic cylinder 72 is a model with fast response and high-precision positioning functions, which can accurately drive the positioning rod assembly 71 through the opening on the mold base 3 into the fixed groove 4 to accurately clamp and position the parts therein, thereby ensuring that the nut position will not shift during processing, and thus ensuring the accuracy of assembly pressing.

[0035] At the same time, such as Figures 2-6 As shown, the pressing mechanism 7 includes a mounting bracket 73 disposed above the worktable 1, a material seat 74 disposed above the mold base 3 on the mounting bracket 73, the material seat 74 being hollow, having a placement groove 75 for placing a pad in the middle, and being able to slide up and down relative to the fixed groove 4, and being able to be inserted and engaged with the fixed groove 4; it also includes a feeding sleeve 76 fixedly disposed on the mounting bracket 73 and located above the material seat 74, the edge of the feeding sleeve 76 having a notch 77 communicating with the second feeding mechanism 6, the second feeding mechanism 6 allowing the pad to enter into the material seat 74 through the notch 77; it also includes a pressing plate 78 disposed above the material seat 74, the pressing plate 78 being able to slide up and down synchronously with the material seat 74 relative to the fixed groove 4 and being able to slide relative to the placement groove 75 of the material seat 74; both the pressing plate 78 and the material seat 74 are connected to the drive assembly.

[0036] Meanwhile, the support assembly 9 is arranged at one end of the placing groove 75 of the material seat 74 relative to the fixed groove 4, and is used to support the gasket in the placing groove 75 and remove the support to the gasket to make the gasket enter the nut when the material seat 74 moves into the fixed groove 4; the support assembly 9 comprises a ring groove 91 arranged at the side of the material seat 74, a limiting plate 92 is slidably arranged in the ring groove 91, the limiting plate 92 extends outwardly and is provided with a driving piece 93, the driving piece 93 is in a plate structure, a through groove is arranged in the middle of the driving piece 93, a driving surface 96 is arranged on the outer side inner wall of the through groove, the driving surface 96 is in abutting fit with the side edge of a control piece 94, meanwhile, the control piece 94 is arranged on the mold seat 3 and is opposite to the driving piece 93, the control piece 94 is in a rod structure and is relatively slidably arranged in the through groove, one end of the control piece 94 towards the material seat 74 is provided with an inclined surface 95, the inclined surface 95 is in abutting fit with the driving surface 96, and the limiting plate 92 can be driven to move away from the placing groove 75 by the driving piece 93; a reset piece 97 is further arranged between the driving piece 93 and the material seat 74, and the reset piece 97 is a reset spring.

[0037] The driving assembly comprises a first telescopic cylinder 10 arranged on the mounting bracket 73, an output shaft is arranged on the first telescopic cylinder 10, the head of the output shaft is connected with the material seat 74, the tail end of the output shaft is connected with a connecting frame 16 which moves synchronously with the material seat 74, and the connecting frame 16 is provided with a second telescopic cylinder 11 connected with the pressing plate 78.

[0038] Meanwhile, an insertion groove 13 is arranged at the end surface of the material seat 74 and is opposite to the position of the through groove, the insertion groove 13 is in plug-in fit with the control piece 94, and a sensor which can be triggered by the end of the control piece 94 is arranged in the insertion groove 13, and the sensor is electrically connected with the second telescopic cylinder 11.

[0039] Specifically, the mounting bracket 73 is fixed on the workbench 1 by a nut, and the material seat 74 is slidably arranged on the mounting bracket 73. The material seat 74 is located above the mold seat 3 and is hollow, and has a placement slot 75 for placing the gasket. The material seat 74 can slide up and down relative to the fixed slot 4 and is inserted and matched with the fixed slot 4. Above the material seat 74, there is a feeding sleeve 76, and a notch 77 is formed in the edge of the feeding sleeve 76 and is communicated with the second feeding mechanism 6, so that the gasket can enter the material seat 74. The structure and working principle of the second feeding mechanism 6 are the same as those of the first feeding mechanism 5. In addition, the pressing plate 78 above the material seat 74 can slide up and down relative to the fixed slot 4 synchronously with the material seat 74, and can slide relative to the placement slot 75. The pressing plate 78 and the material seat 74 are connected with the driving assembly. One end of the placement slot 75 of the material seat 74 is provided with a supporting assembly 9, which includes a limiting plate 92 slidably arranged in a circumferential slot 91, a driving piece 93 extending outward from the limiting plate 92, and a control piece 94 correspondingly arranged on the mold seat 3. The control piece 94 can drive the limiting plate 92 to move away from the placement slot 75 through the driving piece 93. The driving piece 93 and the material seat 74 are further provided with a reset piece 97. The driving piece 93 has a plate-shaped structure, and a driving surface 96 is arranged on the outer side inner wall of the through slot in the middle. The control piece 94 has a rod shape, and an inclined surface 95 at one end abuts against the driving surface 96. The insertion slot 13 in the end surface of the material seat 74 corresponds in position to the through slot, and a sensor in the insertion slot 13 can be triggered by the end of the control piece 94 and is electrically connected with the second telescopic cylinder 11.

[0040] When the material seat 74 is inserted and matched with the fixed slot 4 under the action of the first telescopic cylinder 10 in the assembly and pressing station, the supporting assembly 9 can ensure the stability of the gasket in the placement slot 75. As the material seat 74 continues to move downward, the control piece 94 interacts with the driving piece 93 to drive the limiting plate 92 to move, thereby removing the support of the gasket and allowing the gasket to accurately fall into the nut. During this process, the inclined surface 95 of the control piece 94 closely matches the driving surface 96 of the driving piece 93, and the accurate action of the limiting plate 92 is realized through precise mechanical transmission. At the same time, after the sensor in the insertion slot 13 in the end surface of the material seat 74 is triggered by the end of the control piece 94, the second telescopic cylinder 11 is controlled to push the pressing plate 78 to press downward, thereby completing the pressing action. This precise triggering mechanism and orderly action cooperation ensure the accurate assembly and pressing of the gasket and the nut, thereby improving the quality and consistency of the product. At the same time, since the second telescopic cylinder 11 is arranged at the tail end of the first telescopic cylinder 10 through the connecting frame 16, the synchronous lifting of the pressing plate 78 and the material seat 74 can be realized, thereby ensuring that the distance between the pressing plate 78 and the material seat 74 remains unchanged and ensuring that the pressing plate 78 can smoothly enter the material seat 74.

[0041] Through the above technical solutions, the continuous and stable rotation of the conveying disc 2, combined with the efficient cooperative work of each station, reduces the downtime and waiting time in the production process. In particular, the pressing mechanism 7 can simultaneously complete the feeding, assembly and pressing of the gasket and the nut in one process, avoiding the conversion time between different processes, greatly shortening the processing cycle of a single part, and significantly improving the overall production efficiency.

[0042] And the accurate positioning of the positioning rod group 71 to the nut before assembly and pressing, as well as the accurate feeding of the feeding mechanism to the nut and the gasket, combined with the high-precision cooperation of the material seat 74, the pressing plate 78 and the linear guide and other components, effectively reduces the positional deviation and error of the parts during processing, greatly improves the assembly and pressing accuracy, and ensures that each completed fastener meets strict quality standards.

[0043] And the traditional mechanical arm grabbing and placing operation is cancelled in the present application, avoiding the adjustment of complex mechanical arm motion trajectory and grabbing force. The relative positions of the conveying disc 2, the mold seat 3, the feeding mechanism and the pressing mechanism 7 are fixed and reasonably designed, reducing the debugging work caused by improper position adjustment and cooperation, reducing the difficulty of equipment installation and maintenance, and saving a lot of debugging time and labor cost.

[0044] And the precise linkage of the sensor and the control member 94 enables the release and pressing action of the gasket to be performed at the right time, ensuring that the gasket accurately enters the nut and completes high-quality pressing. At the same time, the same mechanism realizes assembly and pressing, avoiding the problem of error accumulation and inconsistent cooperation between different mechanisms, improving the consistency and stability of the product, and effectively ensuring the assembly quality and reliability of each fastener.

[0045] Among them, the sensor can be a proximity switch, which is connected with the PLC control board in the controller, and the controller is connected with the motor and the telescopic cylinder in the present application, so as to realize the control of the equipment.

[0046] As shown in Figure 6 The discharging mechanism 8 includes a third telescopic cylinder 12 arranged on the workbench 1 and corresponding to the opening position on the mold seat 3, and a friction wheel 14 connected to the output end of the third telescopic cylinder 12 through a connecting rod, the friction wheel 14 being rotationally arranged on the connecting rod and driven by a motor; and a discharging channel 15 arranged on the workbench 1 and corresponding to the opening position, the friction wheel 14 being capable of feeding the nut from the fixed groove 4 into the discharging channel 15.

[0047] When the assembled and pressed die holder 3 is rotated to the discharging station, the third telescopic cylinder 12 is actuated to push the connecting rod to make the friction wheel 14 close to the fixed groove 4. The motor drives the friction wheel 14 to rotate, and the friction wheel 14 contacts the nut to generate friction force, thereby pushing the nut out of the fixed groove 4. The nut moves in a specific direction under the action of friction force, and finally enters the discharging channel 15 corresponding to the position.

[0048] Among them, on the side of the friction wheel 14, an upper rubber layer can be provided to increase the friction force while avoiding damage to the fastener; through the above carefully designed structure action, an efficient and automated discharging process is realized. Without manual tedious operation, the discharging efficiency and automation level are greatly improved. Stable and continuous discharging action ensures that the products can be discharged in an orderly manner, providing great convenience for subsequent processing links, effectively ensuring the continuity and efficiency of the entire production process, and effectively avoiding production interruption due to poor or delayed discharging links.

[0049] Working principle:

[0050] The servo motor in the control module drives the conveying disc 2 to rotate at a constant speed on the workbench 1 through the rotating shaft. The die holder 3 on the edge of the conveying disc 2 rotates with it, first reaching the feeding station.

[0051] At the feeding station, the vibration disc 51 of the first feeding mechanism 5 arranges and conveys the nuts in an orderly manner through vibration of a specific frequency. The linear feeder uses the internal spiral track to push the nuts to the guide pipe 52 at a stable speed. The guide pipe 52 is precisely connected with the opening on the die holder 3 to accurately send the nuts into the fixed groove 4. Each fixed groove 4 can only accommodate one nut at a time, and the excess nuts will be blocked and wait, thereby effectively controlling the number of nut conveying.

[0052] The die holder 3 loaded with nuts is then rotated to the assembly and pressing station. At this station, the fourth telescopic cylinder 72 drives the positioning rod group 71 to pass through the opening of the die holder 3 into the fixed groove 4 to accurately position the nut.

[0053] At the same time, the second feeding mechanism 6 conveys the gasket to the feeding sleeve 76, and the gasket enters the placement groove 75 of the material holder 74 through the gap 77. The first telescopic cylinder 10 pushes the material holder 74 to move downward and insert with the fixed groove 4, and the support assembly 9 initially supports the gasket. As the material holder 74 continues to move downward, the control member 94 on the die holder 3 interacts with the driving member 93, the driving limiting plate 92 moves, the support of the gasket is released, and the gasket falls into the nut. When the sensor in the end face insertion slot 13 of the material holder 74 is triggered by the end of the control member 94, the second telescopic cylinder 11 pushes the pressing plate 78 to press downward, and the pressing of the gasket and the nut is completed.

[0054] The die holder 3 is finally rotated to the discharging station after the assembly and pressing are completed. At this time, the third telescopic cylinder 12 is actuated to push the connecting rod so that the friction wheel 14 approaches the fixed groove 4. The motor drives the friction wheel 14 to rotate, the friction wheel 14 contacts the nut to generate a friction force, the nut is pushed out of the fixed groove 4, and the nut moves in a specific direction under the action of the friction force and finally enters the discharging channel 15, thereby achieving automatic discharging.

[0055] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. within the design concept of the present application shall be included in the protection scope of the present application.
