Description

Technical Field

[0001] This utility model relates to the field of automated assembly equipment technology, and more specifically, to a pin feeding mechanism for an assembly machine. Background Technology

[0002] A spring pin is a common mechanical connector, usually made of metal. Its structure is an open tube, which relies on its own elastic deformation to achieve an interference fit with the hole. It is widely used in shaft and hole connection and positioning in the fields of automobiles, aerospace, and precision instruments. Among them, the pin is the core component of the spring pin, and its assembly quality directly affects the reliability and stability of the connection.

[0003] Currently, the feeding of flexible pins mostly uses a combination of vibratory feeders and linear vibratory feeding to sort and transport parts. The linear vibratory guide rail continuously vibrates, moving the arranged parts into a receiving slot within a steering disc. The steering disc then rotates to transfer the horizontal pins to a vertical position, where pneumatic grippers move them to a designated location. However, during the orientation and transfer of smooth, small pins, after the parts move from the vibratory guide rail into the receiving slot, the pins are prone to sliding or falling out when the steering disc rotates. This requires stopping the machine for adjustment, affecting the stability and production efficiency of continuous operation. Therefore, we have made improvements and proposed a pin feeding mechanism for assembly machines. Summary of the Invention

Multiple feeding components for transferring the parts to the carrier plates are installed on the upper end of the base. A control panel is fixedly installed on one side of the upper end of the base.

A toggle frame is fixedly connected to the outside of the rotating rod, and the toggle frame is located at the upper end of the linear vibration guide rail.

[0010] As a preferred technical solution of this application, the steering wheel has two symmetrically arranged sliding cavities. A set of springs is fixedly connected to the inner wall of each sliding cavity on the side away from the storage groove, and the springs are in pairs.

[0011] As a preferred technical solution of this application, a movable plate is slidably connected in both sliding cavities, and the two movable plates are respectively fixedly connected to the front ends of two sets of springs. A wedge block is fixedly connected to one side of each of the two movable plates. The two wedge blocks pass through the two sliding cavities respectively, and the two wedge blocks are slidably arranged in the storage groove.

[0012] As a preferred technical solution of this application, the feeding component includes a support frame, which is fixedly connected to the upper end of the base. An electric guide rail is fixedly connected to one side of the support frame, and a movable frame is slidably installed on the outside of the electric guide rail.

[0013] As a preferred technical solution of this application, a lifting cylinder is fixedly installed on the upper end of the mobile frame, the output end of the lifting cylinder is fixedly connected to the lifting frame, a slide rail is fixedly connected to one side of the mobile frame, the lifting frame is slidably connected to the outside of the slide rail, and a pneumatic gripper is fixedly installed on the lower end of the lifting frame.

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0020] As described in the background art, during the orientation and transfer of smooth, small pin parts, after the parts move from the linear guide rail to the receiving slot, the pins are prone to sliding or falling off in the receiving slot when the steering wheel rotates, requiring machine stoppage for adjustment, which affects the stability of continuous equipment operation and production efficiency.

[0021] To solve this technical problem, this utility model provides a pin feeding mechanism for an assembly machine, which is applied to the automated feeding of pins in a flexible pin assembly machine.

[0022] For details, please refer to Figures 1-5 The pin-feeding mechanism for the assembly machine specifically includes: The base 1 is used for support, the disc assembly 2 is used to drive the workpiece to rotate, and multiple workpiece placement plates 3 are used to place the workpiece. The disc assembly 2 is installed at the middle of the upper end of the base 1. Multiple workpiece placement plates 3 are arranged in a ring array on the upper end of the disc assembly 2. Multiple processing components 4 for orienting and sorting the parts are installed on the side wall of the base 1. Multiple loading components 5 for transferring the parts to the workpiece placement plates 3 are installed on the upper end of the base 1. A control panel 6 is fixedly installed on one side of the upper end of the base 1.

[0023] The assembly machine pin-feeding mechanism provided by this utility model realizes automatic sorting, orientation and conveying of parts through processing component 4, improving feeding efficiency and consistency. Processing component 4 can change the posture of parts from horizontal conveying state to vertical placement state, preparing for subsequent gripping by feeding component 5. When changing the posture of parts, processing component 4 can stably and elastically clamp the parts, and the parts can be safely and reliably fixed in processing component 4 until they reach the feeding station, effectively preventing the parts from falling off during rotation. It realizes efficient, stable and non-destructive automated feeding and transfer of parts, significantly improving the reliability of equipment operation and production efficiency. Furthermore, feeding component 5 can quickly, stably and accurately grip the elastically clamped parts, and then transfer the parts and place them on the designated carrier plate 3 above the disc component 2. The whole process has a high degree of automation, accurate positioning and fast cycle time, directly ensuring the continuous and efficient operation of the equipment.

[0024] It is worth noting that both the disc assembly 2 and the control panel 6 are existing technologies. The disc assembly 2 is the core conveying system of the equipment, consisting of a precision divider, a drive motor, and a ring turntable. The ring turntable is hollow and its working principle is to receive PLC pulse signals through the divider to achieve precise intermittent indexing motion, driving the carrier plate 3 of the ring array to pass through each station in sequence. The control panel 6 integrates a PLC controller and a touch screen human-machine interface. Through programming, it coordinates the station switching of the divider, the action sequence of the processing component 4 and the feeding component 5, and the interaction of sensor signals to realize the automated cyclic control and parameter setting of the entire processing flow. In addition, the upper end of the base 1 is also equipped with processing components and stamping components for sequentially loading internal components such as nuts, which will not be described in detail here.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0026] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] Example 1, please refer to Figures 1-5A pin-feeding mechanism for an assembly machine includes a base 1 for support, a disc assembly 2 for rotating the workpiece, and multiple carrier plates 3 for placing the workpiece. The disc assembly 2 is installed at the middle of the upper end of the base 1. Multiple carrier plates 3 are arranged in a ring array on the upper end of the disc assembly 2. Multiple processing components 4 for orienting and sorting the parts are installed on the side wall of the base 1. Multiple feeding components 5 for transferring the parts to the carrier plates 3 are installed on the upper end of the base 1. A control panel 6 is fixedly installed on one side of the upper end of the base 1. The disc assembly 2 drives the ring carrier plates 3 to change work positions through intermittent rotation. After the processing components 4 automatically orient, sort, and arrange the parts, they detect the part positioning signal through photoelectric sensors and trigger the feeding components 5. The feeding components 5 then accurately grab the positioned parts and transfer them to the corresponding carrier plates 3 for placement. The entire process is centrally coordinated and controlled by the control panel 6, realizing the automated connection between the part processing and feeding processes. The sensor triggering mechanism ensures the precise synchronization of the action sequence, significantly improving the feeding accuracy, equipment operating cycle time, and production efficiency.

[0029] Furthermore, such as Figures 1-3 As shown, the processing component 4 includes a mounting frame 401, which is fixedly connected to one side of the base 1. A vibratory feeder 402 is fixedly installed at the center of the upper end of the base 1, and a linear vibration guide rail 403 is fixedly installed at the upper end of the base 1. The feed end of the linear vibration guide rail 403 is fixedly connected to the discharge end of the vibratory feeder 402. The vibratory feeder 402 automatically sorts and orients the disordered parts, and the linear vibration guide rail 403 continuously transports the ordered parts to the designated position, realizing the automation and continuity of parts supply, significantly improving the feeding efficiency and consistency. At the same time, the overall structure is firmly connected to the base 1 through the mounting frame 401, ensuring the stability and reliability during the vibration operation.

[0030] Furthermore, such as Figures 3-4 As shown, a vertical plate 404 is fixedly connected to the upper end of the base 1. A first motor 405 is fixedly installed on one side of the vertical plate 404. A steering wheel 406 is fixedly connected to the output end of the first motor 405. A storage slot 407 is provided on the outside of the steering wheel 406. The steering wheel 406 is driven to rotate by the first motor 405. The storage slot 407 on the outside of the steering wheel 406 is used to receive and transfer parts. The sensor set on the side wall of the steering wheel 406 can detect the position of the steering wheel 406 in real time. When a specific mark is detected on the side of the feeding component 5, a signal is sent to the control system, causing the first motor 405 to stop immediately. This ensures that the steering wheel 406 stops accurately at the specified angle, realizing the automated closed-loop control of part posture conversion and workstation positioning, which greatly improves the accuracy of the feeding position and the reliability of equipment operation.

[0031] Furthermore, such as Figure 3 and Figure 4As shown, a connecting plate 408 is fixedly connected to one side of the upright plate 404. A second motor 409 is fixedly installed on the side wall of the connecting plate 408. The output end of the second motor 409 passes through the connecting plate 408, and a rotating rod 410 is fixedly connected to the output end of the second motor 409. A toggle frame 411 is fixedly connected to the outside of the rotating rod 410. The toggle frame 411 is located at the upper end of the linear vibration guide rail 403. The second motor 409 drives the rotating rod 410 and the toggle frame 411 to rotate, accurately moving the parts at the end of the linear vibration guide rail 403 into the storage slot 407 of the steering wheel 406. Due to the transmission mechanism set on the side wall of the steering wheel 406... The sensor can detect the position of the steering wheel 406 in real time. Therefore, the second motor 409 will only operate when the receiving slot 407 is directly aligned with the vertical vibration guide rail 403, thereby ensuring precise synchronization between the material feeding action and the steering wheel 406 position. The second motor 409 receives pulse signals from the control system or performs closed-loop position feedback through the encoder, so that the output of the second motor 409 drives the shifting frame 411 to rotate one revolution each time a part is shifted. This design not only achieves high precision and zero interference in part transfer, but also effectively avoids mechanism collisions or parts missing during shifting, significantly improving the reliability and continuity of the feeding process.

[0032] Furthermore, such as Figure 5 As shown, the steering wheel 406 has two symmetrically arranged sliding cavities 412. A set of springs 413 is fixedly connected to the inner wall of each sliding cavity 412 on the side away from the storage groove 407. The springs 413 are in pairs. A movable plate 414 is slidably connected to each sliding cavity 412. The two movable plates 414 are respectively fixedly connected to the front ends of the two sets of springs 413. A wedge block 415 is fixedly connected to one side of each movable plate 414. The two wedge blocks 415 pass through the two sliding cavities 412 respectively, and are slidably positioned in the storage groove 407. During the process of inserting the part into the receiving slot 407, the side wall of the part will contact two wedge blocks 415. The wedge blocks 415 are pushed by the force, and the inclined surface of the wedge blocks 415 decomposes the force, causing the spring 413 to contract. The wedge blocks 415 contract a certain distance into the sliding cavity 412. After the part enters the receiving slot 407, the two wedge blocks 415 clamp the part located in the receiving slot 407 under the pre-pressure of the spring 413, so that when the steering wheel 406 rotates, the part can be safely and reliably fixed in the receiving slot 407 until it reaches the loading station.

[0033] Example 2 further optimizes the pin-feeding mechanism for the assembly machine provided in Example 1. Specifically, as follows: Figures 1-3As shown, the feeding assembly 5 includes a support frame 501, which is fixedly connected to the upper end of the base 1. An electric guide rail 502 is fixedly connected to one side of the support frame 501. A movable frame 503 is slidably mounted on the outside of the electric guide rail 502. A lifting cylinder 504 is fixedly mounted on the upper end of the movable frame 503. A lifting frame 505 is fixedly connected to the output end of the lifting cylinder 504. A slide rail 506 is fixedly connected to one side of the movable frame 503. The lifting frame 505 is slidably connected to the outside of the slide rail 506. A pneumatic gripper 507 is fixedly mounted on the lower end of the lifting frame 505. When the steering wheel 406 stops the storage slot 407 holding the vertically positioned part on the feeding assembly 5... When directly below, the electric guide rail 502 drives the moving frame 503 to move horizontally, so that the pneumatic gripper 507 at the end is precisely aligned with the part. Then, the lifting cylinder 504 works to push the lifting frame 505 to descend vertically along the slide rail 506 to ensure the stability of the movement. After the pneumatic gripper 507 descends to the preset position, the gripper closes and firmly grasps the part fixed by the wedge block 415. Then, the lifting cylinder 504 lifts the pneumatic gripper 507, and the electric guide rail 502 moves in the opposite direction to transport the part to the corresponding carrier plate 3 on the disc assembly 2. The whole process is highly automated, with accurate positioning and fast cycle time, which directly ensures the continuous and efficient operation of the equipment.

[0034] It is worth noting that both the electric guide rail 502 and the pneumatic gripper 507 are existing technologies. The electric guide rail 502 drives a precision lead screw or synchronous belt through a drive device to realize the linear reciprocating motion of the moving frame 503, providing high-precision horizontal positioning. The pneumatic gripper 507 is controlled by a solenoid valve to open and close the gripper fingers, realizing the gripping and release of parts. The loading component 5 mainly relies on the control panel 6 and the PLC system to coordinate the stroke of the electric guide rail 502, the lifting timing of the lifting cylinder 504, and the action logic of the pneumatic gripper 507 through programming. At the same time, it receives the station positioning signal from the disc component 2 to ensure that the loading action and the station conversion are completely synchronized, thereby realizing the reliable transfer of parts.

[0035] Example 3 further optimizes the pin-feeding mechanism for the assembly machine provided in Example 1. Specifically, as follows: Figure 1 and Figure 2 As shown, casters 7 are fixedly connected to the four corners of the lower end of the base 1, and electric lifting feet 8 are fixedly connected to the four corners of the lower end of the base 1. The casters 7 enable flexible movement and position adjustment of the equipment. The electric lifting feet 8 support and level the equipment base 1 after positioning. The casters 7 provide flexibility of movement, while the electric lifting feet 8 ensure that the bottom of the feet is firmly in contact with the ground and bears the weight of the equipment. This not only ensures the convenience of moving the equipment, but also ensures the stability and shock absorption requirements of the equipment during operation through electric leveling, effectively avoiding precision deviations caused by vibration during processing. The lower end of the mounting frame 401 is also fixedly installed with electric lifting feet 8.

[0036] Furthermore, such as Figure 5 As shown, the wedge block 415 has an anti-slip pad 9 on its side wall. The anti-slip pad 9 is made of rubber. The rubber anti-slip pad 9 on the side wall of the wedge block 415 increases the friction of the contact surface and buffers the clamping force when clamping parts. This effectively prevents smooth parts from sliding or falling off during the rotation of the steering wheel 406, and also avoids scratches or indentations on the surface of parts caused by rigid clamping. This significantly improves the reliability of clamping and the protection of the product.

[0037] The usage process of the pin-feeding mechanism for the assembly machine provided by this utility model is as follows: The pin parts are poured into the vibratory feeder 402. The vibratory feeder 402 automatically arranges the parts into a uniform posture and then sends them out onto the linear vibration guide rail 403. The linear vibration guide rail 403 continuously transports the oriented parts forward to the edge of the steering disc 406 through linear vibration. Then, the second motor 409 is started, driving the rotating rod 410 and the actuating frame 411 on it to rotate. During the rotation, the actuating frame 411 accurately moves individual parts into the storage slots 407 on the steering disc 406. During the process of moving the parts into the storage slots 407, the sidewalls of the parts will contact two wedge blocks 415. The wedge blocks 415 are pushed by a force. The inclined surface of block 415 decomposes the thrust, causing spring 413 to contract. Wedge block 415 contracts a distance into sliding cavity 412. When the part enters storage groove 407, the two wedge blocks 415 clamp the part in storage groove 407 under the pre-pressure of spring 413, so that when steering wheel 406 rotates, the part can be safely and reliably fixed in storage groove 407 until it reaches the loading station. Then the first motor 405 starts and drives the entire steering wheel 406 to rotate a specific angle, changing the posture of the part from horizontal conveying state to vertical placement state, which is ready for the subsequent loading component 5 to grab. When the steering wheel 406 stops the storage slot 407 holding the vertically positioned part directly below the loading assembly 5, the electric guide rail 502 drives the moving frame 503 to move horizontally, so that the pneumatic gripper 507 at the end is precisely aligned with the part. Then, the lifting cylinder 504 works, pushing the lifting frame 505 to descend vertically along the slide rail 506 to ensure the stability of the movement. After the pneumatic gripper 507 descends to the preset position, the gripper closes, firmly grasping the part fixed by the wedge block 415. Then, the lifting cylinder 504 lifts the pneumatic gripper 507, and the electric guide rail 502 moves in the opposite direction to transport the part to the corresponding carrying plate 3 on the disc assembly 2. The whole process is highly automated, with precise positioning and fast cycle time, which directly ensures the continuous and efficient operation of the equipment.
