[0015] An assembly machine for an automatic relay coil snap-fit ​​device.

[0016] The beneficial effects of this invention are as follows: This invention addresses the shortcomings and deficiencies of existing technologies by independently developing and designing an automatic relay coil clamping and pressing device and its assembly machine that enables automatic rotation feeding of relay coils, adaptive elastic clamping and fixing, and simultaneous release of relay coils to improve feeding and releasing efficiency. Furthermore, it achieves Z-shaped path pressing through a single power drive, effectively avoiding motion interference.

[0017] This invention aims to provide a solution for the field of automatic relay assembly, enabling adaptive elastic clamping and swivel feeding of relay coils and Z-shaped path pressing, achieving automatic feeding, unloading, and pressing of relay coils, effectively improving relay coil assembly efficiency and saving assembly power consumption. Specifically, the invention includes an assembly platform, a transfer feeding mechanism, and a pressing mechanism. The assembly platform includes a fixture and a clamping and limiting component. A material slot on the fixture holds the relay hook to be assembled. When the clamping and limiting component, located on the side of the fixture, approaches the fixture, it engages with the positioning block of the fixture through a positioning groove on the inner wall of the positioning plate at the top of the limiting vertical plate, for positioning and clamping the limiting component. Simultaneously, the limiting groove at the outer end of the limiting plate on the limiting vertical plate nests into the outer wall of the relay coil to guide and limit the relay coil during the pressing assembly process. Simultaneously, clamping strips located on both sides of the limiting plate... Driven by the clamping cylinder, the clamping bar approaches the limiting plate from the outside. The clamping bar and the semi-circular groove of the limiting plate are joined to form a circular groove, which is then fitted onto the two insertion rods of the relay coil. This guides the insertion rods as they are snapped into the relay hook along with the relay coil. The insertion rods, passing through the circular groove, are inserted downwards into the positioning hole of the fixture seat. While guiding the insertion rods, this prevents them from being pushed against the fixture seat and deformed. The clamping and limiting components clamp and limit the relay coil and insertion rods, ensuring the positional accuracy of the relay coil and insertion rods during the pressing and snapping assembly process. They also help protect the insertion rods, preventing bending and deformation during the pressing process.

[0018] Furthermore, the present invention realizes the automatic receiving, feeding and releasing of relay coils through a transfer feeding mechanism. After the transfer feeding mechanism clamps and fixes the relay coil supplied by the external feeding mechanism, it drives the relay coil to rotate 180° to the top of the fixture and puts the relay coil into the relay hook on the fixture so that the subsequent pressing mechanism can press and fasten the relay coil into the relay hook. The unique feature is that the transfer feeding mechanism employs a combination of lifting and rotating motion to transport relay coils received from external feeding mechanisms and place them on the assembly platform. The transfer feeding mechanism uses a lifting cylinder to drive the lifting slide, providing vertical lifting power. A swing cylinder positioned above the support sleeve pushes a drive rack within the support sleeve, converting the vertical linear power into drive teeth that rotate the support shaft within the support sleeve, thereby rotating the connecting rotating seat and swing arm mounted on the support shaft. Through the meshing of the drive teeth and drive rack, the vertical power is converted into rotational power. This toothed drive method allows for precise control of the swing arm's rotation angle, ensuring accurate feeding. Furthermore, the outer end of the swing arm of the present invention is provided with a clamping head. The clamping head uses a clamping seat with a clamping groove that runs vertically through the interior as the receiving body of the relay coil. The clamping seat is connected and fixed to the outer end of the swing arm through a mating seat provided on the side. The clamping groove at the top of the clamping seat is provided with upward protruding mating protrusions on the left and right sides respectively. When the clamping seat is rotated to the top of the fixture by the swing arm, the mating protrusions are embedded in the mating hole of the fixture to position and fix the clamping seat, so as to ensure that the relay coil is accurately placed into the material groove of the fixture. Furthermore, clamping insertion holes are horizontally provided on the left and right sides of the clamping groove. The clamping insertion holes penetrate the side wall of the clamping seat and communicate with the clamping groove. A clamping block is slidably inserted into the clamping insertion hole. The cap of the outer end of the clamping block is connected to the outer seat set on the outside of the clamping seat through a horizontally set clamping spring. The clamping block is driven to move into the clamping groove by the elastic force of the clamping spring so as to elastically and adaptively clamp and fix the relay coil placed in the clamping groove. When the swing arm drives the clamping head to move above the fixture and puts the relay coil into the material groove of the fixture, the gap space between the clamping block of the clamping head and the clamping seat is nested in the positioning plate of the clamping limit component. As it descends, the positioning plate pushes the clamping block outward, so that the clamping block releases the relay coil while placing it.

[0019] Furthermore, the pressing mechanism of the present invention adopts a Z-shaped path pressing motion to press the relay coil on the fixture into the relay hook. This pressing method can effectively avoid motion interference with the transfer feeding mechanism during the pressing process. In particular, the pressing mechanism of the present invention drives the pressing plate to complete the pressing action of the relay coil in a Z-shaped path direction, which is achieved by a single vertical power drive output from the pressing cylinder. When the pressing cylinder drives the pressing slide to move downward, it drives the pressing support plate and the adjusting slide connected to it by the horizontal guide rail to descend synchronously. When the adjusting slide drives the pressing plate to move downward, the rollers are nested in the inclined guide groove opened on the side pressing guide plate and move along the inclined guide groove. The inclined guide groove extending along the Z-shape provides a reaction force to the adjusting slide through the rollers, so that the adjusting slide moves horizontally along the guide rail while moving vertically. Through the slidable connection between the adjusting slide and the guide rail, motion interference when the adjusting slide drives the pressing plate to press in a Z-shaped path is avoided.

Example 2

[0055] As an embodiment of the present invention, the present invention discloses an assembly machine for an automatic relay coil snap-fit ​​device.

[0056] Furthermore, this invention designs an automatic relay coil clamping and pressing device and its assembly machine that realizes automatic swing-type feeding of relay coils, adaptive elastic clamping and fixing, and simultaneous release and release of relay coils, thereby improving feeding and releasing efficiency. It also achieves Z-shaped path pressing through a single power drive, effectively avoiding motion interference. This invention aims to provide a solution for the field of automatic relay assembly, realizing adaptive elastic clamping swing-type feeding and Z-shaped path pressing of relay coils, achieving automatic feeding, releasing, and clamping pressing of relay coils, effectively improving relay coil assembly efficiency and saving assembly power consumption. Specifically, the invention comprises an assembly platform, a transfer feeding mechanism, and a pressing mechanism. The assembly platform includes a jig and a clamping and limiting component. A material groove on the jig holds a relay hook to be assembled. When the clamping and limiting component, located on the side of the jig, approaches the jig, it engages with the positioning block of the jig via a positioning groove on the inner wall of the positioning plate at the top of the limiting vertical plate, for positioning and clamping the limiting component. Simultaneously, a limiting groove at the outer end of the limiting plate on the limiting vertical plate nests on the outer wall of the relay coil to guide and limit the relay coil during the pressing assembly process. Simultaneously, clamping strips located on both sides of the limiting plate... Driven by the clamping cylinder, the clamping bar approaches the limiting plate from the outside. The clamping bar and the semi-circular groove of the limiting plate are joined to form a circular groove, which is then fitted onto the two insertion rods of the relay coil. This guides the insertion rods as they are snapped into the relay hook along with the relay coil. The insertion rods, passing through the circular groove, are inserted downwards into the positioning hole of the fixture seat. While guiding the insertion rods, this prevents them from being pushed against the fixture seat and deformed. The clamping and limiting components clamp and limit the relay coil and insertion rods, ensuring the positional accuracy of the relay coil and insertion rods during the pressing and snapping assembly process. They also help protect the insertion rods, preventing bending and deformation during the pressing process.

[0057] Furthermore, the present invention realizes the automatic receiving, feeding and releasing of relay coils through a transfer feeding mechanism. After the transfer feeding mechanism clamps and fixes the relay coil supplied by the external feeding mechanism, it drives the relay coil to rotate 180° to the top of the fixture and puts the relay coil into the relay hook on the fixture so that the subsequent pressing mechanism can press and fasten the relay coil into the relay hook. The unique feature is that the transfer feeding mechanism employs a combination of lifting and rotating motion to transport relay coils received from external feeding mechanisms and place them on the assembly platform. The transfer feeding mechanism uses a lifting cylinder to drive the lifting slide, providing vertical lifting power. A swing cylinder positioned above the support sleeve pushes a drive rack within the support sleeve, converting the vertical linear power into drive teeth that rotate the support shaft within the support sleeve, thereby rotating the connecting rotating seat and swing arm mounted on the support shaft. Through the meshing of the drive teeth and drive rack, the vertical power is converted into rotational power. This toothed drive method allows for precise control of the swing arm's rotation angle, ensuring accurate feeding. Furthermore, the outer end of the swing arm of the present invention is provided with a clamping head. The clamping head uses a clamping seat with a clamping groove that runs vertically through the interior as the receiving body of the relay coil. The clamping seat is connected and fixed to the outer end of the swing arm through a mating seat provided on the side. The clamping groove at the top of the clamping seat is provided with upward protruding mating protrusions on the left and right sides respectively. When the clamping seat is rotated to the top of the fixture by the swing arm, the mating protrusions are embedded in the mating hole of the fixture to position and fix the clamping seat, so as to ensure that the relay coil is accurately placed into the material groove of the fixture. Furthermore, clamping insertion holes are horizontally provided on the left and right sides of the clamping groove. The clamping insertion holes penetrate the side wall of the clamping seat and communicate with the clamping groove. A clamping block is slidably inserted into the clamping insertion hole. The cap of the outer end of the clamping block is connected to the outer seat set on the outside of the clamping seat through a horizontally set clamping spring. The clamping block is driven to move into the clamping groove by the elastic force of the clamping spring so as to elastically and adaptively clamp and fix the relay coil placed in the clamping groove. When the swing arm drives the clamping head to move above the fixture and puts the relay coil into the material groove of the fixture, the gap space between the clamping block of the clamping head and the clamping seat is nested in the positioning plate of the clamping limit component. As it descends, the positioning plate pushes the clamping block outward, so that the clamping block releases the relay coil while placing it.

[0058] Furthermore, the pressing mechanism of the present invention adopts a Z-shaped path pressing motion to press the relay coil on the fixture into the relay hook. This pressing method can effectively avoid motion interference with the transfer feeding mechanism during the pressing process. In particular, the pressing mechanism of the present invention drives the pressing plate to complete the pressing action of the relay coil in a Z-shaped path direction, which is achieved by a single vertical power drive output from the pressing cylinder. When the pressing cylinder drives the pressing slide to move downward, it drives the pressing support plate and the adjusting slide connected to it by the horizontal guide rail to descend synchronously. When the adjusting slide drives the pressing plate to move downward, the rollers are nested in the inclined guide groove opened on the side pressing guide plate and move along the inclined guide groove. The inclined guide groove extending along the Z-shape provides a reaction force to the adjusting slide through the rollers, so that the adjusting slide moves horizontally along the guide rail while moving vertically. Through the slidable connection between the adjusting slide and the guide rail, motion interference when the adjusting slide drives the pressing plate to press in a Z-shaped path is avoided.
