However, such equipment has its drawbacks: during the assembly process, multiple workstation switching operations are required to complete the positioning and assembly of screws and washers.

Summary of the Invention

[0011] In some embodiments, the second mounting position is a second stepped hole structure opened on the top surface of the second turntable.

The inner diameter of the third hole segment is adapted to the outer diameter of the gasket. The inner diameter of the fourth hole segment is smaller than the inner diameter of the third hole segment.
[0012] In some embodiments, the screw washer assembly apparatus further includes: The first feeding component is fixed to the frame and corresponds to the feeding side of the first turntable. The discharge port of the first feeding component faces the first mounting position and can feed the screw into the first mounting position that has been rotated to the feeding position. A first correction component is disposed on the frame and located on the working path between the discharge port of the first feeding component and the first mounting position. The first correction component includes a first correction block and a fourth driving member. The fourth driving member is connected to the first correction block and can drive the first correction block to move in a direction closer to or further away from the first mounting position.
[0013] In some embodiments, the screw washer assembly apparatus further includes: The second feeding component is located on the frame and corresponds to the feeding side of the second turntable. The second feeding component and the first feeding component are spaced apart along the circumference of the turntable. The discharge port of the second feeding component is adapted to the position of the second mounting position and can feed the pad into the second mounting position that has been rotated to the feeding position. The second correction component is disposed on the frame and located on the working path between the discharge port of the second feeding component and the second mounting position.

The first mounting position on the circumference of the first turntable and the second mounting position on the circumference of the second turntable correspond one-to-one along the radial direction of the turntable. During rotation, the screw in the first mounting position and the washer in the second mounting position can be simultaneously transported to the designated working area. After being transported to the position, a clamping mechanism located on the frame and movable radially along the turntable is activated to clamp the screw in the first mounting position and adjust its position by radial movement, so that the screw is accurately aligned with the washer in the corresponding second mounting position. Subsequently, the drive component of the assembly drive mechanism drives the working head to move. The working head contacts the screw clamped by the clamping mechanism and applies force to insert the screw into the washer in the corresponding second mounting position, completing the assembly operation of a set of screws and washers. Continuous assembly can be achieved by continuously rotating the turntable. This application achieves synchronous transport of screws and washers through the design of a double-layer turntable and radially corresponding mounting positions, which can complete the positioning of both without multiple workstation switching, greatly shortening the single assembly cycle.

[0022] Please refer to Figures 1 to 3 This application discloses a screw washer assembly device 100, comprising: Rack 10; Turntable 20 is rotatably mounted on frame 10. Turntable 20 includes a first turntable 21 and a second turntable 22 arranged at intervals along the vertical direction. The first turntable 21 is provided with a plurality of first mounting positions 211 for placing screws along the circumference. The second turntable 22 is provided with a plurality of second mounting positions 221 for placing washers along the circumference. The first mounting positions 211 and the second mounting positions 221 are arranged in a one-to-one correspondence along the radial direction of turntable 20. The clamping mechanism 30 is mounted on the frame 10 and is movably mounted radially along the turntable 20. The clamping mechanism 30 is used to clamp the screw in the first mounting position 211 and align the screw with the washer in the corresponding second mounting position 221. The assembly drive mechanism 40 includes a drive assembly 41 and a working head 42. The working head 42 is connected to the power output end of the drive assembly 41. The drive assembly 41 can drive the working head 42 to move so that the working head 42 contacts the screw held by the clamping mechanism 30 and inserts the screw into the washer in the corresponding second mounting position 221.
[0023] In this embodiment, the frame 10 serves as the basic support component of the entire equipment, undertaking the role of fixing and bearing all other functional components. It provides a stable installation reference for the turntable 20, the clamping mechanism 30, and the assembly drive mechanism 40, ensuring that each component maintains the accuracy of its relative position during operation and avoiding the impact of the frame 10's shaking or deformation on the assembly accuracy.
[0024] The turntable 20 is a component that enables synchronous conveying of screws and washers and station switching. It is rotatably mounted on the frame 10, and its rotation drives the first turntable 21 and the second turntable 22 to move synchronously. The first turntable 21 has several first mounting positions 211 arranged circumferentially to support the screws to be assembled, providing temporary placement and positioning space for the screws and ensuring that the screws do not shift or fall off during conveying. The second turntable 22 has several second mounting positions 221 arranged circumferentially to place the washers to be mated with the screws, which also serve to position and convey the washers.
[0025] Furthermore, the first mounting position 211 and the second mounting position 221 are arranged in a one-to-one correspondence along the radial direction of the turntable 20. This design ensures that during the rotation of the turntable 20, each screw in the first mounting position 211 can accurately correspond to a washer in the second mounting position 221, laying the foundation for subsequent alignment and assembly processes and realizing the synchronous delivery and precise matching of screws and washers.
[0026] The clamping mechanism 30 is used for clamping and aligning screws. It is radially movable on the frame 10 along the turntable 20 and can adjust its position according to the operation requirements. When the turntable 20 transports the first mounting position 211 and the corresponding second mounting position 221 to the working area of the clamping mechanism 30, the clamping mechanism 30 can move to the first mounting position 211 to stably clamp the screw therein, preventing the screw from shifting during the subsequent alignment process. Then, the clamping mechanism 30 drives the clamped screw to move radially along the turntable 20, so that the axis of the screw coincides with the axis of the washer in the corresponding second mounting position 221, realizing the precise alignment of the screw and the washer, providing positional assurance for the subsequent press-fit assembly process, and avoiding assembly failure or quality problems due to alignment deviation.
[0027] The assembly drive mechanism 40, serving as the power output component for press-fitting screws and washers, consists of a drive assembly 41 and a working head 42. The drive assembly 41, as a power source, provides the driving force required for assembly. Its power output end is connected to the working head 42, driving it to move in a preset direction. The working head 42, acting directly on the screw, applies pressure to the screw held by the clamping mechanism 30 under the drive of the drive assembly 41. Once the screw and washer are aligned, the working head 42, driven by the drive assembly 41, contacts the screw and continuously applies pressure, smoothly and accurately pressing the screw into the washer in the corresponding second mounting position 221, creating a stable mating connection between the screw and washer, thus completing the entire assembly process.
[0028] When the screw washer assembly equipment 100 of this embodiment is working, the turntable 20 drives the first turntable 21 and the second turntable 22 to rotate synchronously, so that the first mounting position 211 and the second mounting position 221 distributed along the circumference arrive at the preset working position in sequence; with the help of the radial movement function of the clamping mechanism 30, the clamping and positioning alignment operation of the screw in the first mounting position 211 is completed; then the assembly drive mechanism 40 provides power, and the working head 42 presses the aligned screw into the washer in the second mounting position 221, forming an integrated assembly process, breaking the traditional multi-station switching operation mode, and realizing the continuity and efficiency of the assembly process.
[0029] Compared to traditional semi-automatic assembly equipment that requires multiple station switching to complete assembly, this application integrates the assembly process into a continuous action flow through synchronous rotary conveying of the turntable 20, radial alignment of the clamping mechanism 30, and direct pressing of the assembly drive mechanism 40. This eliminates the need for component transfer between multiple stations, significantly shortens the operation cycle of a single assembly, effectively improves the overall assembly efficiency of the equipment, and better meets the efficiency requirements of mass production scenarios.
[0030] Furthermore, the first mounting position 211 and the second mounting position 221 of the turntable 20 are arranged radially in a one-to-one correspondence, structurally ensuring the initial pairing accuracy of the screw and washer. On the other hand, the clamping mechanism 30 can move radially to achieve precise alignment of the screw and washer, avoiding the component misalignment problem that easily occurs during station switching in traditional equipment. At the same time, the assembly drive mechanism 40 applies a stable pressing force to the screw through the working head 42, ensuring that the screw can be smoothly installed into the washer, reducing the occurrence of quality problems such as missing washer and uneven tightening force, and improving the stability of assembly quality.
[0031] In this embodiment, the actions of each component are highly adjustable. For example, parameters such as the rotation speed of the turntable 20, the travel of the clamping mechanism 30, and the pressing force of the assembly drive mechanism 40 can all be adjusted according to different specifications of screws and washers. Without the need for large-scale modification of the overall equipment structure or re-adjustment of multiple station parameters, it is possible to adapt to the assembly operations of screws and washers of different specifications, effectively shortening the debugging time when switching specifications, improving the equipment's adaptability to flexible production lines, and meeting diverse production needs.
[0032] In some embodiments, the first mounting position 211 and the second mounting position 221 of each group are located on the same radial straight line passing through the rotation center of the turntable 20, and the projections of the first mounting position 211 and the second mounting position 221 in the vertical direction do not overlap.
[0033] In this embodiment, the distribution along the same radial straight line eliminates the need for a complex positioning and calibration mechanism on the turntable 20. This ensures that each set of screws and washers maintains a radial correspondence during rotational transport, further enhancing the turntable 20's ability to precisely match screws and washers. Furthermore, the non-overlapping vertical projections allow the turntable 20 to rationally allocate the vertical installation space for both the first and second turntables 21, avoiding structural interference caused by overlapping projections. This also provides a reasonable spatial layout for the subsequent clamping mechanism 30 and assembly drive mechanism 40, improving the overall structural compatibility and operational reliability of the turntable 20.
[0034] Since the vertical projections of the first mounting position 211 and the second mounting position 221 do not overlap, when the clamping mechanism 30 clamps the screw from the first mounting position 211 and moves radially to align with the inner washer of the second mounting position 221, it does not need to avoid the overlapping area of the two mounting positions in the vertical direction. It can move smoothly along the preset radial path, reducing the action avoidance steps of the clamping mechanism 30 and simplifying the motion control logic of the clamping mechanism 30. At the same time, it avoids the action jamming or position deviation that may be caused by the need to avoid the overlapping area, ensuring that the clamping mechanism 30 can complete the alignment operation of the screw and the washer more accurately and efficiently, further ensuring the alignment accuracy and operational stability.
[0035] The design of the first mounting position 211 and the second mounting position 221 in this embodiment, where their vertical projections do not overlap, structurally reduces the possibility of the clamping mechanism 30 colliding and interfering with the first turntable 21, the second turntable 22, or components within the mounting positions during the movement of the clamping screw. Compared to the potential problems of mechanism jamming and component wear that might occur if their projections overlap, this embodiment effectively protects the integrity of the clamping mechanism 30 and the turntable 20, reduces the risk of equipment failure caused by mechanism interference, and improves the safety and reliability of the equipment during operation.
[0036] Furthermore, since the first mounting position 211 and the second mounting position 221 of each group are always located on the same radial straight line, there is no need to perform real-time calibration and adjustment of their radial positions when the turntable 20 rotates. The clamping mechanism 30 only needs to move along a fixed radial path to complete the alignment of the screw and the washer. There is no need for complex multi-dimensional position compensation control, which simplifies the motion control program design of the equipment, reduces the computational load and debugging difficulty of the control system, reduces the action delay or error that may be caused by the complexity of the control logic, and further improves the stability and response speed of the equipment operation.
[0037] In some embodiments, please refer to Figure 3 The clamping mechanism 30 includes: Clamping claw assembly 31, which is used to clamp the screw in the first mounting position 211; The first driving member 32 is disposed on the frame 10, and the power output end of the first driving member 32 is connected to the clamping claw assembly 31. The first driving member 32 can drive the clamping claw assembly 31 to move radially along the turntable 20.
[0038] In this embodiment, the clamping claw assembly 31, as the component of the clamping mechanism 30 that directly contacts the screw, is used to stably clamp the screw within the first mounting position 211. The structural design of the clamping claw assembly 31 must be adapted to the shape of the screw to ensure that it can closely fit the screw surface during clamping, preventing the screw from loosening, shifting, or being damaged while clamped. At the same time, the clamping claw assembly 31 must have an appropriate clamping force adjustment capability to ensure reliable clamping of the screw, preventing it from falling off during movement, and to avoid deformation or damage to the screw surface due to excessive clamping force, thus providing a good condition guarantee for the subsequent alignment and assembly of the screw.
[0039] The first driving component 32 serves as the power source for the clamping mechanism 30, driving the clamping claw assembly 31 to move precisely radially along the turntable 20. The first driving component 32 is fixedly mounted on the frame 10, and its power output end forms a stable connection with the clamping claw assembly 31, smoothly transmitting its output power to the clamping claw assembly 31. By controlling the first driving component 32, the moving speed, travel distance, and stop position of the clamping claw assembly 31 can be precisely adjusted, ensuring that when the clamping claw assembly 31 moves the screw, it accurately reaches the preset position aligned with the inner washer of the second mounting position 221. This avoids inaccurate screw-waist matching due to movement deviation, providing reliable power support for the clamping mechanism 30 to achieve precise screw alignment.
[0040] In this embodiment, the power provided by the first driving member 32 drives the clamping claw assembly 31 connected thereto to move radially and precisely along the turntable 20. When the turntable 20 transports the first mounting position 211 to the preset working position, the clamping claw assembly 31 can stably clamp the screw in the first mounting position 211. Then, driven by the first driving member 32, the clamping claw assembly 31 moves radially with the screw to the position aligned with the gasket in the corresponding second mounting position 221. This provides a precise position guarantee for the subsequent assembly drive mechanism 40 to press the screw into the gasket, so that the clamping and moving actions of the clamping mechanism 30 are coordinated, further improving the accuracy and stability of screw clamping and alignment.
[0041] In some embodiments, please refer to Figure 3 The clamping claw assembly 31 includes two clamping claws 311 arranged opposite to each other, and the two clamping claws 311 can be closed to form a clamping groove 312 that is adapted to the shape of the outer wall of the screw. The second driving member 33 is connected to at least one of the two clamping claws 311. The second driving member 33 can drive the clamping claw 311 connected to it to move closer to or further away from the other clamping claw 311.
[0042] In this embodiment, the two opposing clamping claws 311 are the core components that form the clamping groove 312 and directly contact and fix the screw. Their opposing inner sidewalls need to be adapted to the shape of the outer wall of common screws (such as cylindrical, hexagonal, etc.) to ensure that when the two are closed, they can form a clamping groove 312 that fits completely with the outer wall of the screw. The size of the clamping groove 312 needs to match the specification of the target screw to ensure that the screw can be stably wrapped during clamping, restricting the screw's displacement in the radial and circumferential directions, and avoiding the screw being unable to be put in smoothly or being damaged by excessive clamping due to the size deviation of the clamping groove 312.
[0043] The second drive unit 33 establishes a power connection with at least one clamping claw 311 and can output a driving force in the opposite direction according to the operation command: when a clamping command is received, the clamping claw 311 connected to it is driven to move closer to another clamping claw 311, so that the two are closed to form a clamping groove 312 and apply a stable clamping force to the screw; when a release command is received, the clamping claw 311 is driven to move away from the other clamping claw 311, so that the clamping groove 312 opens to release the constraint on the screw.
[0044] In this embodiment, the clamping groove 312 formed by the two clamping claws 311 fits the outer wall of the screw, which can form a wrapping fixation of the screw. Compared with the traditional single-point or single-side clamping method, it can effectively limit the circumferential rotation and radial displacement of the screw during the clamping process. Even if the clamping claws 311 encounter slight vibration during movement, the screw posture can be kept stable, reducing the risk of screw falling off or position deviation caused by unstable clamping, and further ensuring the accuracy of subsequent alignment and assembly processes.
[0045] Furthermore, in this embodiment, the opening and closing distance of the two clamping claws 311 can be adjusted by the second driving component 33, thereby changing the size of the clamping slot 312. This allows the same set of clamping claws 311 to accommodate screws of different diameters. Simultaneously, by replacing them with clamping claws 311 of different inner wall shapes (such as polygonal clamping claws 311 for hexagonal screws and arc-shaped clamping claws 311 for cylindrical screws), the clamping requirements of screws with different outer wall shapes can also be met. There is no need to design a separate clamping mechanism for each screw size, significantly improving the versatility of the clamping claw assembly 31 and reducing the modification costs when adapting the equipment to different production needs.
[0046] In some embodiments, please refer to Figure 2 The first mounting position 211 is a first stepped hole structure that penetrates the first turntable 21. The side wall of the first stepped hole structure has a first opening 212 that extends to the outer peripheral wall of the first turntable 21. The first stepped hole structure includes a first hole section 213 and a second hole section 214 that are coaxially arranged. The first hole section 213 is close to the top surface of the second turntable 22. The inner diameter of the first hole section 213 is adapted to the outer diameter of the screw nut. The inner diameter of the second hole section 214 is smaller than the inner diameter of the first hole section 213.
[0047] In this embodiment, the first stepped hole structure serves as the carrier of the first mounting position 211, providing precise positioning and accommodating space for the screw. Specifically, the overall stepped structure uses the size difference of different hole segments to doubly restrict the axial and radial positions of the screw, preventing the screw from axially shifting or radially deviating during the rotation of the turntable 20, ensuring that the screw is always in a preset position that is easy for the clamping mechanism 30 to hold, thus laying the positioning foundation for subsequent alignment and assembly processes.
[0048] The first opening 212 is located on the side wall of the first stepped hole structure and extends to the outer peripheral wall of the first turntable 21. It serves as a screw feeding channel and is also compatible with the operational requirements of the clamping claw assembly 31. During the feeding stage, the conveying component of the screw feeding mechanism can extend into or align with the first stepped hole structure through the first opening 212 to accurately feed the screw into the hole, ensuring that the screw enters the limiting space formed by the first hole section 213 and the second hole section 214 in a preset posture. In addition, when the turntable 20 rotates the first mounting position 211 to the working area of the clamping mechanism 30, the clamping claw assembly 31 can remove the screw from the first mounting position 211 through the first opening 212, achieving functional compatibility between feeding and clamping operations.
[0049] In this embodiment, the dimensions of the first hole segment 213 and the second hole segment 214 are adapted to the screw, nut and screw rod (or the bottom of the nut), respectively. Through the dual action of radial constraint and axial limit, the position and posture height of the screw in the first mounting position 211 are fixed, avoiding the screw from shifting or tilting due to centrifugal force or vibration during the rotation of the turntable 20, reducing the clamping error caused by the screw posture deviation, and further ensuring the smoothness of the assembly process.
[0050] Furthermore, the first opening 212 serves as a dedicated feeding channel, allowing the screw feeding mechanism to directly feed screws radially along the first turntable 21 through the first opening 212 without having to transport materials from the upper and lower end faces of the first turntable 21. This reduces spatial interference between the feeding mechanism and the upper and lower components of the turntable 20, and lowers the risk of screw jamming during the feeding process.
[0051] In some embodiments, please refer to Figure 4 and Figure 5 The screw washer assembly equipment 100 also includes a material blocking mechanism 50, which includes a third driving member 51 and a material blocking member 52. The third driving member 51 is fixed to the frame 10 and is arranged on the outer periphery of the first turntable 21. The material blocking member 52 is connected to the power output end of the third driving member 51. The third driving member 51 can drive the material blocking member 52 to move in a direction close to or away from the first opening 212 to block or open the first opening 212.
[0052] In this embodiment, the third driving component 51 serves as the power source for the material blocking mechanism 50, providing controllable power for the movement of the material blocking component 52. It is fixed to the frame 10 and is set on the outer periphery of the first turntable 21. It can accurately output driving force according to the operation process instructions of the equipment (such as the work position signal of the first installation position 211) to control the material blocking component 52 to move along a preset direction (closer to or further away from the first opening 212).
[0053] As an actuator that directly acts on the first opening 212, the stopper 52 achieves the blocking and opening of the first opening 212 through its own positional changes. When the third drive member 51 drives the stopper 52 to approach the first opening 212, the stopper 52 can conform to the outer peripheral wall of the first turntable 21 or be embedded in the edge of the first opening 212, forming a closed structure for the first opening 212, preventing the screw in the first stepped hole structure from coming out of the opening; when the third drive member 51 drives the stopper 52 away from the first opening 212, the stopper 52 is completely separated from the first opening 212, leaving sufficient space for the screw feeding operation and the removal of the clamping claw assembly 31.
[0054] In this embodiment, the third driving member 51 drives the movement of the stop member 52 to achieve targeted blocking and delayed opening of the first opening 212, thereby assisting the clamping mechanism 30 in stably clamping the screw. When the turntable 20 drives the first mounting position 211 to the assembly station, the third driving member 51 first drives the stop member 52 to approach and block the first opening 212, so that the screw in the first stepped hole structure is confined in a closed space, preventing the screw from shifting in the opening direction due to force when the clamping claw assembly 31 contacts the screw; after the clamping claw assembly 31 of the clamping mechanism 30 has completely clamped the screw, the third driving member 51 then drives the stop member 52 away to open the first opening 212, making room for the clamping claw assembly 31 to drive the screw to move radially and align with the washer.
[0055] During the clamping process, the stop 52 effectively restricts the lateral displacement of the screw by blocking the first opening 212, preventing problems such as clamping misalignment and gripping failure caused by the screw's force deviation when the clamping claw assembly 31 contacts the screw. Compared to the situation where the screw tends to slide towards the opening when clamped without a stop structure, the stop 52 provides stable lateral support for the screw, enabling the clamping claw assembly 31 to more accurately align with the screw's preset clamping position, reducing the clamping error rate and improving the stability and success rate of the clamping process.
[0056] Furthermore, the third drive unit 51 controls the opening and closing sequence of the stop 52 according to the action state of the clamping mechanism 30, so that the action of the stop 52 first blocking to assist clamping and then opening to cooperate with the movement is precisely connected with the action of the clamping claw assembly 31 first approaching to grab and then driving the movement. This avoids the situation where the stop 52 blocks the movement or opens too early, resulting in unstable clamping, thereby reducing the waiting time between processes, ensuring the continuity of clamping and subsequent alignment processes, and further improving the overall operating efficiency of the equipment.
[0057] In some embodiments, please refer to Figure 2 The second mounting position 221 is a second stepped hole structure opened on the top surface of the second turntable 22. The side wall of the second stepped hole structure has a second opening 222, which extends to the outer peripheral wall of the second turntable 22. The second stepped hole structure includes a third hole section 223 and a fourth hole section 224 arranged coaxially. The third hole section 223 is close to the top surface of the second turntable 22. The inner diameter of the third hole section 223 is adapted to the outer diameter of the gasket. The inner diameter of the fourth hole section 224 is smaller than the inner diameter of the third hole section 223.
[0058] In this embodiment, the second stepped hole structure serves as the core carrier of the second mounting position 221, providing precise positioning and accommodating space for the gasket. The overall stepped structure, through the size difference of different hole segments, provides dual restriction on the axial position and radial displacement of the gasket, preventing the gasket from axially shifting or radially deviating during the rotation of the turntable 20, ensuring that the gasket is always in the preset position corresponding to the screw in the first mounting position 211, thus laying the positioning foundation for the precise assembly of the screw and the gasket.
[0059] The second opening 222 is located on the side wall of the second stepped hole structure and extends to the outer peripheral wall of the second turntable 22, providing a channel for gasket feeding, condition inspection, and assembly adaptation. During the feeding stage, the gasket feeding mechanism can accurately feed the gasket into the second stepped hole structure through the second opening 222, ensuring that the gasket enters the hole in a preset direction (e.g., flat surface facing upwards). During the condition inspection stage, the inspection component can observe or inspect whether there are any abnormalities such as missing or reversed gaskets through the second opening 222, facilitating timely troubleshooting. In addition, when the screw is pressed onto the gasket, the second opening 222 can accommodate the discharge of any trace amounts of gas or the cleaning of impurities, preventing the assembly quality from being affected by the pressure or impurities inside the hole, while not affecting the normal rotation of the turntable 20 or the operation of other stations.
[0060] The third hole segment 223 and the fourth hole segment 224 are coaxially arranged, and together they achieve precise positioning of the gasket. The third hole segment 223 is located near the top surface of the second turntable 22, and its inner diameter matches the outer diameter of the gasket, providing radial constraint on the outer periphery of the gasket and preventing radial wobble or displacement within the hole. The inner diameter of the fourth hole segment 224 is smaller than that of the third hole segment 223, and the junction of the two forms a stepped surface. This stepped surface provides axial support to the bottom surface of the gasket, limiting excessive movement of the gasket into the second turntable 22. This ensures that the gasket maintains a preset posture within the second mounting position 221 with its top surface facing upwards and its bottom surface conforming to the stepped surface, ensuring that the screw accurately acts on the preset position of the gasket (such as the center hole) during screw pressing, and preventing inaccurate screw-gasket mating due to gasket posture deviation.
[0061] In this embodiment, the dimensions of the third hole segment 223 and the fourth hole segment 224 are adapted to the outer diameter of the gasket and the bottom support requirements, respectively. Through the dual action of radial constraint and axial limit, the position and posture height of the gasket in the second mounting position 221 are fixed, avoiding the gasket from shifting or tilting due to centrifugal force or vibration during the rotation of the turntable 20. This ensures that the screw delivered by the clamping mechanism 30 can be accurately aligned with the gasket, reducing assembly failures caused by alignment deviations and further ensuring the assembly quality of the screw and gasket.
[0062] Moreover, the second opening 222 in this embodiment provides a convenient radial feeding channel for the gasket feeding mechanism. The feeding mechanism does not need to carry out complex material conveying from above or below the second turntable 22. It can directly feed the gaskets radially through the opening, reducing the risk of spatial interference and jamming during the feeding process. At the same time, the gasket status can be quickly detected through the second opening 222 without disassembling the second turntable 22 or stopping the equipment operation, which shortens the time for troubleshooting abnormalities. The operation process is optimized from the feeding and detection links, improving the overall operating efficiency of the equipment and making it more suitable for the continuous operation needs of mass production.
[0063] It should be understood that by adjusting the inner diameter and step height of the third hole section 223 and the fourth hole section 224, the second step hole structure can be adapted to gaskets with different outer diameters and thicknesses. If a change in production specifications is required, only the second turntable 22 with the corresponding size second step hole needs to be replaced. There is no need to carry out large-scale modifications to the overall structure of the turntable 20, the feeding mechanism, or the assembly drive mechanism 40. This reduces the difficulty and cost of equipment specification switching, enhances the equipment's adaptability to diverse production needs, and expands the equipment's application range.
[0064] In some embodiments, please refer to Figure 1 and Figure 7 The screw washer assembly equipment 100 also includes: The first feeding component 60 is fixed to the frame 10 and corresponds to the feeding side of the first turntable 21. The discharge port of the first feeding component 60 faces the first mounting position 211 and can feed screws into the first mounting position 211 that has been rotated to the feeding position. The first correction component 70 is disposed on the frame 10 and located on the working path between the discharge port of the first feeding component 60 and the first mounting position 211. The first correction component 70 includes a first correction block 71 and a fourth driving member 72. The fourth driving member 72 is connected to the first correction block 71 and can drive the first correction block 71 to move in a direction closer to or further away from the first mounting position 211.
[0065] In this embodiment, the first feeding component 60 is fixed to the frame 10 and corresponds to the feeding side of the first turntable 21, providing stable and directional feeding of screws to the first mounting position 211. The position and angle of the discharge port of the first feeding component 60 must be adapted to the first opening 212 of the first mounting position 211 to ensure that the screws can smoothly enter the first stepped hole structure along the preset path.
[0066] The fourth driving component 72 serves as the power source for the first correction assembly 70, driving the first correction block 71 to move towards or away from the first mounting position 211. The first correction block 71, acting directly on the screw, achieves attitude adjustment and position calibration through contact with the screw. When the fourth driving component 72 drives it closer to the first mounting position 211, it can apply a pushing force by contacting the screw surface, straightening tilted nuts and pushing screws that are not fully inserted into the hole into the first hole segment 213 of the first stepped hole structure, ensuring that the screw's attitude meets subsequent clamping requirements.
[0067] In addition, the first correction block 71 can also physically block the screws to be conveyed after the discharge port of the first feeding component 60, preventing the subsequent screws from entering the working path at an inappropriate time, and preventing multiple screws from stacking and blocking the first opening 212 or interfering with the correction of the previous screw; after the previous screw has completed the correction and stably entered the first mounting position 211, the fourth driving component 72 drives the first correction block 71 away, releasing the obstruction of the subsequent screws and allowing the next screw to enter the conveying path.
[0068] The first correction component 70 in this embodiment can effectively solve the problem of abnormal screw posture caused by conveying vibration and path deviation during the feeding process. Through the precise pushing of the first correction block 71, the offset screw is adjusted to the preset posture and ensures that it is fully inserted into the first mounting position 211, avoiding the situation where the clamping mechanism 30 cannot accurately clamp the screw due to tilting or misalignment. Moreover, the material blocking function of the first correction block 71 can effectively avoid the problem of screw stacking caused by the continuous feeding of the first feeding component 60. When the previous screw has not been corrected or positioned, the first correction block 71 physically blocks the subsequent screw from entering, preventing multiple screws from accumulating in the first opening 212 or the first stepped hole structure to form a blockage, reducing production interruptions caused by blockage, and further ensuring the continuity of equipment operation.
[0069] In some embodiments, please refer to Figure 6 The screw washer assembly equipment 100 also includes: The second feeding component 80 is located on the frame 10 and corresponds to the feeding side of the second turntable 22. The second feeding component 80 and the first feeding component 60 are arranged circumferentially on the turntable 20. The discharge port of the second feeding component 80 is adapted to the position of the second mounting position 221 and can feed the pad into the second mounting position 221 that has been rotated to the feeding position. The second correction component 90 is disposed on the frame 10 and located on the working path between the discharge port of the second feeding component 80 and the second mounting position 221. The second correction component 90 includes a second correction block 91 and a fifth driving member 92. The fifth driving member 92 is connected to the second correction block 91 and can drive the second correction block 91 to move in a direction closer to or away from the second mounting position 221.
[0070] In this embodiment, the second feeding component 80 is located on the frame 10 and corresponds to the feeding side of the second turntable 22, providing stable and directional feeding of the pads to the second mounting position 221. The outlet position and angle of the second feeding component 80 are adapted to the second opening 222 of the second mounting position 221, ensuring that the pads can smoothly enter the second stepped hole structure along a preset path.
[0071] The fifth driving component 92, as the power source of the second alignment assembly 90, drives the second alignment block 91 to move in a direction closer to or further away from the second mounting position 221. The second alignment block 91, as an actuator that directly acts on the shim, achieves attitude adjustment and position calibration through contact with the shim. When the fifth driving component 92 drives it closer to the second mounting position 221, it can apply a pushing force by contacting the shim surface, leveling any tilted shims and pushing shims that are not fully inserted into the hole into the third hole segment 223 of the second stepped hole structure, ensuring that the shim's attitude meets the requirements for subsequent screw pressing.
[0072] In addition, the second correction block 91 can also physically block the subsequent pads to be conveyed at the outlet of the second feeding component 80, preventing the subsequent pads from entering the working path at an inappropriate time, and preventing multiple pads from stacking and blocking the second opening or interfering with the correction of the previous pad; after the previous pad has completed the correction and stably entered the second mounting position 221, the fifth driving component 92 drives the second correction block 91 away, releasing the obstruction of the subsequent pads and allowing the next pad to enter the conveying path.
[0073] The second correction component 90 in this embodiment can effectively solve the problem of abnormal posture of the gasket caused by conveying vibration and path deviation during the feeding process. Through the precise pushing of the second correction block 91, the offset gasket is adjusted to the preset posture and ensures that it is fully inserted into the second mounting position 221, avoiding the situation where the screw is offset, missing, or cannot be fully embedded in the center hole of the gasket due to the posture deviation of the gasket. Moreover, the material blocking function of the second correction block 91 can effectively avoid the problem of gasket stacking caused by the continuous feeding of the second feeding component 80. When the previous gasket has not been corrected or positioned, the second correction block 91 prevents the subsequent gasket from entering by physically blocking it, preventing multiple gaskets from accumulating in the second opening 222 or the second stepped hole structure to form a blockage, reducing the production interruption caused by the blockage, and further ensuring the continuity of equipment operation.
[0074] Preferably, both the first feeding component 60 and the second feeding component 80 can adopt a vibratory feeder structure. Utilizing the high-frequency vibration of the vibratory feeder and its internal guide rail design, automated sorting, directional conveying, and stable-speed feeding of screws and washers are achieved. Specifically, the vibratory feeder of the first feeding component 60 can sort disordered screws according to a preset posture and then accurately convey them through the discharge port to the first mounting position 211, which has rotated to the feeding position. The vibratory feeder of the second feeding component 80 can sort disordered washers according to a preset posture (flat surface facing upwards, center hole and second step hole coaxial) and then accurately feed them through the discharge port adapted to the second mounting position 221. The vibration frequencies of both components can be matched with the rotation rhythm of the turntable 20, ensuring coordinated feeding rate and station switching rate. Furthermore, the structural characteristics of the vibratory feeder can accommodate screws and washers of different specifications. Material specification switching can be achieved by adjusting the internal guide rail, without requiring large-scale modifications to the overall structure of the feeding components. This ensures both the stability and accuracy of the feeding process and enhances the equipment's adaptability to diverse production needs.
[0075] In some embodiments, the working head 42 has a positioning groove at the end away from the drive assembly 41, and the positioning groove is adapted to the shape of the screw and nut; and / or, Drive assembly 41 includes a linear drive unit 411 and a rotary drive unit 412. The linear drive unit 411 can drive the working head 42 to move vertically to achieve screw pressing, and the rotary drive unit 412 can drive the working head 42 to rotate around its own axis to insert the screw into the washer by rotary pressing; and / or, The screw washer assembly equipment 100 also includes a feeding assembly 101, which is located on the frame 10 and corresponds to the discharge side of the second turntable 22. The feeding assembly 101 includes a sixth drive member 102, a pusher plate 103, and a receiving member 104. The receiving member 104 is fixed to the frame 10 and located outside the second turntable 22. The pusher plate 103 is connected to the power output end of the sixth drive member 102. The sixth drive member 102 can drive the pusher plate 103 to move in a direction close to the second mounting position 221 to push the screw-wafer assembly in the second mounting position 221 into the receiving member 104.
[0076] In this embodiment, the working head 42 serves as the execution component of the assembly drive mechanism 40. Its positioning groove at the end furthest from the drive assembly 41 is used to achieve precise positioning and posture constraint of the screws and nuts. Specifically, the shape of the positioning groove is adapted to the shape of the screws and nuts (such as hexagonal, circular, square, etc.) to ensure a tight fit when in contact with the nuts, limiting the nut's circumferential rotation tendency and preventing screw thread damage or press-fit misalignment caused by screw rotation during the pressing process.
[0077] When the working head 42 contacts the screw, the positioning groove can form a wrapping positioning for the screw and nut, restricting the circumferential rotation and radial displacement of the screw during the pressing process. When the drive assembly 41 drives the working head 42 to move towards the screw held by the clamping mechanism 30, the positioning groove first precisely fits with the screw and nut to establish a stable positioning relationship before applying the pressing force. This ensures that the screw is smoothly pressed into the washer in the second mounting position 221 along the preset axial direction, avoiding assembly deviation caused by the screw's posture shift during the pressing process, and further improving the accuracy and stability of the screw and washer pressing.
[0078] Please refer to Figure 1 and Figure 8 The linear drive unit 411 serves as the axial power source for the drive assembly 41, driving the working head 42 to move precisely in the vertical direction and providing axial pressure for screw pressing. It can control the moving speed and stroke of the working head 42 according to the assembly process instructions: during the positioning stage, the drive working head 42 slowly approaches the screw to ensure that the positioning groove and the nut fit smoothly and avoid the screw's posture deviation due to impact; during the pressing stage, it outputs stable axial pressure, which, in conjunction with the rotation of the rotary drive unit 412, pushes the screw to gradually screw into the washer. The pressure can be adjusted according to the material characteristics of the screw and the washer (such as metal hardness and washer elasticity) to avoid the screw not being fully inserted due to insufficient pressure, or the washer being damaged or the screw being deformed due to excessive pressure.
[0079] The rotary drive unit 412 serves as the circumferential power source for the drive assembly 41, driving the working head 42 to rotate around its own axis and providing circumferential rotational force for screwing the screw into the washer. Its action timing can be precisely matched with that of the linear drive unit 411: rotation is started after the positioning groove and the nut are in contact, avoiding premature rotation that could cause misalignment between the positioning groove and the nut; the rotation speed and direction need to be adapted according to the screw's thread direction (left-hand or right-hand) and pitch to ensure that the screw can be smoothly screwed in along the thread trajectory (or preset guide channel) of the washer's central hole, reducing jamming and wear during thread engagement.
[0080] The rotational force provided by the rotary drive unit 412 in this embodiment enables a screw-on assembly between the screw and the washer, converting the sliding friction of axial pressing into rolling friction (or guiding friction) between the threads, thus reducing assembly resistance. Especially for screw and washer combinations with threads, or in scenarios with hard materials and high precision requirements, rotary pressing can avoid component damage caused by forced pressing, ensure that the screw is stably embedded in the washer, improve the smoothness of the assembly process, and reduce equipment jamming caused by excessive resistance.
[0081] The sixth driving component 102 serves as the power source for the unloading assembly 101, providing a stable and controllable driving force for the pusher plate 103 to achieve precise control of the pushing action. It can be linked with the rotation rhythm of the turntable 20 and the station detection signal to ensure that the drive is started only after the second mounting position 221 reaches the unloading position and the assembly is confirmed to be qualified. During the driving process, the moving speed and stroke of the pusher plate 103 can be precisely controlled: in the initial stage, it moves slowly to avoid the pusher plate 103 impacting the component and causing the component to shift; in the pushing stage, it maintains a uniform speed to ensure that the component smoothly leaves the second mounting position 221; after reaching the position, it promptly reverses the drive to reset the pusher plate 103, reserving space for the next unloading.
[0082] The pusher plate 103 acts directly on the screw-washer assembly, smoothly pushing the assembly out of the second mounting position 221. The receiving part 104 is fixed to the frame 10 and located outside the second turntable 22. It is used to receive the screw-washer assembly pushed out from the second mounting position 221 and guide the assembly into subsequent material flow links (such as conveyor lines, inspection stations).
[0083] When the turntable 20 rotates the second mounting position 221, which contains the assembled screw-washer assembly, to the unloading position, the sixth drive unit 102 receives the station signal and drives the pusher plate 103 to move in the direction close to the second mounting position 221. After the pusher plate 103 contacts the screw-washer assembly, it applies a pushing force to push it out of the second mounting position 221. The pushed screw-washer assembly moves along a preset path under the action of the pushing force and finally falls into the receiving member 104 fixed on the outside of the second turntable 22, completing the collection and transfer of materials, avoiding efficiency loss and material damage caused by manual unloading, and further improving the closed loop of automated operation of the equipment.
[0084] The specific working process of the screw washer assembly equipment 100 in this application is as follows: Turntable 20 starts and drives the first turntable 21 and the second turntable 22 to rotate synchronously. When a set of corresponding first mounting positions 211 and second mounting positions 221 reach their respective feeding positions, turntable 20 pauses. The first feeding component 60 conveys disordered screws through the first opening 212 of the first mounting position 211 into the first stepped hole structure; at the same time, the fourth driving component 72 of the first correction component 70 drives the first correction block 71 to approach the first mounting position 211, and pushes and calibrates the screws that may have posture deviation during the conveying process to ensure that the screws fall completely into the limiting space formed by the first hole section 213 and the second hole section 214, and the first correction block 71 simultaneously blocks the subsequent screws from entering to avoid stacking; Simultaneously, the second feeding component 80 conveys the disordered pads through the second opening 222 of the second mounting position 221 into the second stepped hole structure; the fifth driving component 92 of the second correction component 90 drives the second correction block 91 to approach the second mounting position 221, correcting the attitude of the offset or inverted pads, ensuring that the pads fall smoothly into the limiting space formed by the third hole section 223 and the fourth hole section 224, completing the precise positioning of the pads. After feeding and correction are completed, the first correction block 71 and the second correction block 91 are reset under the drive of their respective driving components, releasing the obstruction to subsequent materials, and the turntable 20 starts again, driving the first mounting position 211 and the second mounting position 221, which are equipped with screws and pads, to rotate synchronously to the next station.
[0085] When the first mounting position 211 with the screw rotates to the clamping position, the turntable 20 pauses. The third drive member 51 of the stop mechanism 50 drives the stop member 52 to approach the first turntable 21, completely blocking the first opening 212 of the first mounting position 211, thus providing lateral support for the screw in the first stepped hole. Subsequently, the first drive member 32 of the clamping mechanism 30 drives the clamping claw assembly 31 to move radially along the turntable 20 above the first mounting position 211, and the second drive member 33 drives the two opposing clamping claws 311 to approach, stably clamping the screw portion through the clamping groove 312 formed by their encirclement. After clamping, the third drive member 51 drives the stop member 52 away from the opening, making room for subsequent screw movement.
[0086] After the clamping claw assembly 31 stably clamps the screw, the first driving member 32 continues to drive the clamping claw assembly 31 to move radially along the turntable 20, approaching the corresponding second mounting position 221. During this process, the turntable 20 remains stationary, ensuring that the first mounting position 211 and the second mounting position 221 are always on the same radial straight line. Since the projections of the first mounting position 211 and the second mounting position 221 in the vertical direction do not coincide, the clamping claw assembly 31 will not interfere with the first turntable 21 and the second turntable 22 when it drives the screw to move. Finally, the axis of the screw is precisely aligned with the axis of the center hole of the inner washer of the second mounting position 221, completing the alignment action.
[0087] After alignment, the assembly drive mechanism 40 is activated: the linear drive unit 411 drives the working head 42 to move downwards in the vertical direction, so that the positioning groove at the end of the working head 42 away from the drive component 41 precisely fits with the screw and nut, forming a dual positioning in the circumferential and radial directions; then, the rotary drive unit 412 drives the working head 42 to rotate around its own axis, while the linear drive unit 411 continuously applies stable axial pressure. Under the combined action of rotational force and axial pressure, the screw is smoothly screwed into the gasket along the thread trajectory (or preset channel) of the gasket's central hole; when the working head 42 moves to the preset pressing depth and the torque of the rotary drive unit 412 reaches the preset threshold, it is determined that the assembly is in place, the rotary drive unit 412 stops rotating, and the linear drive unit 411 drives the working head 42 to return to its original position.
[0088] After assembly, the second drive unit 33 of the clamping mechanism 30 drives the clamping claw assembly 31 to open, releasing the clamp on the screw. The first drive unit 32 drives the clamping claw assembly 31 to reset to the initial area. The turntable 20 starts again, driving the second mounting position 221 with the screw washer assembly to rotate to the unloading station, and at the same time driving the empty first mounting position 211 to rotate to the feeding position, entering the next round of feeding process. When the second mounting position 221 of the unloading station reaches the preset position, the turntable 20 pauses. The sixth drive component 102 of the unloading component 101 drives the pusher plate 103 to move in the direction close to the second mounting position 221. The pusher plate 103 adheres to the surface of the screw washer component and applies a pushing force to push the component out of the second mounting position 221. The pushed component falls into the receiving component 104 fixed on the outside of the second turntable 22 along the preset path and enters the subsequent circulation process through the guide channel of the receiving component 104. The pusher plate 103 is reset under the drive of the sixth drive component 102, and the turntable 20 continues to rotate, entering the continuous cycle assembly process.
[0089] It should be understood that the screw washer assembly equipment 100 of this application embodiment can realize the simultaneous completion of feeding, assembly and unloading. Specifically, after the screw washer assembly equipment 100 completes the initial calibration, reset of each mechanism and debugging of the feeding component before starting, the turntable 20 continuously drives the first turntable 21 and the second turntable 22 to rotate. During this process, one set of installation positions simultaneously completes the feeding and correction of screws and washers, while another set of installation positions that have completed feeding simultaneously carries out the assembly operations of screw clamping, alignment and rotation pressing. At the same time, the assembled screw washer assembly is simultaneously pushed into the receiving part 104 by the pusher plate 103 at the unloading station. The actions of each station are seamlessly connected with the rotation of the turntable 20, forming a continuous synchronous closed-loop operation mode.
