[0015] The utility model relates to an assembly machine for automatically buckling a relay coil into a pressing device.

[0016] The beneficial effects of the present invention are: In view of the defects and shortcomings of the existing technology, the present invention independently developed and designed a device that realizes automatic swing feeding of relay coils, adaptive elastic clamping and fixation, and releases the relay coils in conjunction with discharge, thereby improving feeding and discharge efficiency, and realizing Z-shaped path pressing through a single power drive mode, effectively avoiding motion interference, and automatically buckling the relay coils into the pressing device and its assembly machine.

[0017] The present invention aims to provide a device applied to the field of automatic assembly of relays, which realizes adaptive elastic clamping and swing-type feeding and Z-shaped path pressing of relay coils, realizes automatic feeding, unloading and buckling pressing of relay coils, effectively improves the assembly efficiency of relay coils, and saves assembly power consumption. Specifically, the present invention as a whole includes an assembly platform, a transfer feeding mechanism and a pressing mechanism. The assembly platform includes a jig and a clamping limit component. The relay hook to be assembled is placed in the material trough provided on the jig. When the clamping limit component provided on the side of the jig approaches the jig, it is engaged with the positioning block of the jig through the positioning groove provided on the inner wall of the positioning plate provided on the top of the limiting vertical plate, so as to position the clamping limit component. Simultaneously, the limiting groove on the outer end of the limiting plate provided on the limiting vertical plate is nested on the outer wall of the relay coil, so as to guide the limiting relay coil during the pressing assembly process. Simultaneously, the clamping strips on both sides of the limiting plate are engaged with the positioning block of the jig. Driven by the clamping cylinder, it approaches the limit plate from the outside, and the clamping strip and the semicircular groove of the limit plate are spliced together to form a circular groove body, and are sleeved on the two plug rods of the relay coil, so that the plug rod can guide the limit plug rod when it is buckled into the relay hook along with the relay coil. The plug rod passing through the circular groove body is inserted downward into the positioning hole of the jig seat, while guiding the plug rod, and preventing the plug rod from being pushed on the jig seat and deformed. The clamping and limiting guidance of the relay coil and the plug rod by the clamping and limiting assembly ensures the position accuracy of the relay coil and the plug rod during the press-fit assembly process, and can also assist in protecting the plug rod to avoid bending and deformation during the pressing process of the plug rod.

[0018] Furthermore, the present invention realizes automatic receiving, feeding and unloading 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 flip 180° to the top of the jig, and places the relay coil on the relay hook on the jig, so that the subsequent pressing mechanism can press the relay coil into the relay hook. The special feature is that the feeding method of the transfer feeding mechanism adopts a movement method that combines lifting and rotating motion, so as to transport the relay coil received from the external feeding mechanism and place it on the assembly platform; the transfer feeding mechanism drives the lifting slide to lift and lower through the lifting cylinder to provide lifting power in the vertical direction; the swing cylinder arranged above the support sleeve lifts and lowers in the support sleeve by pushing the driving rack, and converts the linear power in the vertical direction into the driving gear to drive the support shaft in the support sleeve to rotate through the gear connection, so as to drive the connecting swivel seat and the rocker arm arranged on the support shaft to rotate; the vertical power is converted into rotational power through the tooth meshing connection between the driving gear and the driving rack. This tooth connection drive method can accurately control the rotation angle of the rocker arm to ensure feeding accuracy. Furthermore, the outer end of the rocker arm of the present invention is provided with a clamping head, and the clamping head uses a clamping seat with a clamping groove running through the upper and lower parts as the material receiving body of the relay coil, and the clamping seat is connected and fixed to the outer end of the rocker arm through a docking seat provided on the side; the left and right sides of the clamping groove on the top of the clamping seat are respectively provided with upwardly protruding docking protrusions, and when the clamping seat is rotated to the top of the jig under the drive of the rocker arm, the docking protrusions are embedded in the docking holes of the jig to position and fix the clamping seat, thereby ensuring that the relay coil is accurately placed in the material groove of the jig. Furthermore, clamping holes are horizontally provided on the left and right sides of the clamping trough, which pass through the side walls of the clamping seat and are connected to the clamping trough. A clamping block is slidably inserted into the clamping hole, and the cap body at the outer end of the clamping block is connected to the external seat arranged on the outside of the clamping seat through a horizontally arranged clamping spring, and the clamping block is driven to move toward the clamping trough by the elastic force of the clamping spring so as to elastically and adaptively clamp the relay coil fixed in the clamping trough; when the rocker arm drives the clamping head to move above the jig and places the relay coil into the material trough of the jig, the gap space between the clamping block of the clamping head and the clamping seat is correspondingly nested in the positioning plate of the clamping limit assembly, and as it descends, the positioning plate pushes the clamping block outward, so that the clamping block places the relay coil and releases the relay coil at the same time.

[0019] Furthermore, the pressing mechanism of the present invention adopts a movement method of pressing the material in the direction of a Z-shaped path so as to press the relay coil on the jig into the relay hook. This pressing method can effectively avoid interference with the movement of the transfer feeding mechanism during the pressing process; the special feature is that the pressing mechanism of the present invention drives the pressing piece to complete the pressing action of the relay coil in the direction of a Z-shaped path, which is achieved only by a single power drive in the vertical direction output by 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 thereto by the horizontal guide rail to descend synchronously. When the adjusting slide drives the pressing piece to move downward, it is nested in the inclined guide groove opened on the side pressing guide plate through the roller and moves along the inclined guide groove. The inclined guide groove extending along the Z shape provides a reaction force to the adjusting slide through the roller, so that the adjusting slide moves in the vertical direction while moving horizontally along the guide rail. The sliding connection between the adjusting slide and the guide rail is used to avoid interference in the movement when the adjusting slide drives the pressing piece to press in the Z-shaped path.

Example 2

[0055] As one embodiment of the present invention, the present invention discloses an assembly machine for automatically buckling a relay coil into a pressing device.

[0056] Furthermore, the present invention designs a relay coil automatic buckling and pressing device and its assembly machine that realizes automatic swing feeding of relay coils, adaptive elastic clamping and fixation, and simultaneous release of relay coils during discharge, thereby improving feeding and discharge efficiency. Furthermore, the device realizes Z-shaped pressing through a single power drive mode, effectively avoiding motion interference. The present invention aims to provide a relay coil automatic buckling and pressing device for the field of automatic relay assembly, realizing adaptive elastic clamping swing feeding and Z-shaped pressing of relay coils, realizing automatic feeding, discharge, and buckling and pressing of relay coils, effectively improving relay coil assembly efficiency and saving assembly power consumption. Specifically, the present invention as a whole includes an assembly platform, a transfer feeding mechanism and a pressing mechanism. The assembly platform includes a jig and a clamping limit component. The relay hook to be assembled is placed in the material trough provided on the jig. When the clamping limit component provided on the side of the jig is close to the jig, it is embedded in the positioning block of the jig through the positioning groove provided on the inner wall of the positioning plate provided on the top of the limiting vertical plate, which is used to position the clamping limit component; synchronously, the limiting groove at the outer end of the limiting plate provided on the limiting vertical plate is nested on the outer wall of the relay coil, so as to guide the limiting relay coil during the pressing assembly process; synchronously, the clamping strips located on both sides of the limiting plate are engaged in the positioning block of the jig; Driven by the clamping cylinder, it approaches the limit plate from the outside, and the clamping strip and the semicircular groove of the limit plate are spliced together to form a circular groove body, and are sleeved on the two plug rods of the relay coil, so that the plug rod can guide the limit plug rod when it is buckled into the relay hook along with the relay coil. The plug rod passing through the circular groove body is inserted downward into the positioning hole of the jig seat, while guiding the plug rod, and preventing the plug rod from being pushed on the jig seat and deformed. The clamping and limiting guidance of the relay coil and the plug rod by the clamping and limiting assembly ensures the position accuracy of the relay coil and the plug rod during the press-fit assembly process, and can also assist in protecting the plug rod to avoid bending and deformation during the pressing process of the plug rod.

[0057] Furthermore, the present invention realizes automatic receiving, feeding and unloading 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 flip 180° to the top of the jig, and places the relay coil on the relay hook on the jig, so that the subsequent pressing mechanism can press the relay coil into the relay hook. The special feature is that the feeding method of the transfer feeding mechanism adopts a movement method that combines lifting and rotating motion, so as to transport the relay coil received from the external feeding mechanism and place it on the assembly platform; the transfer feeding mechanism drives the lifting slide to lift and lower through the lifting cylinder to provide lifting power in the vertical direction; the swing cylinder arranged above the support sleeve lifts and lowers in the support sleeve by pushing the driving rack, and converts the linear power in the vertical direction into the driving gear to drive the support shaft in the support sleeve to rotate through the gear connection, so as to drive the connecting swivel seat and the rocker arm arranged on the support shaft to rotate; the vertical power is converted into rotational power through the tooth meshing connection between the driving gear and the driving rack. This tooth connection drive method can accurately control the rotation angle of the rocker arm to ensure feeding accuracy. Furthermore, the outer end of the rocker arm of the present invention is provided with a clamping head, and the clamping head uses a clamping seat with a clamping groove running through the upper and lower parts as the material receiving body of the relay coil, and the clamping seat is connected and fixed to the outer end of the rocker arm through a docking seat provided on the side; the left and right sides of the clamping groove on the top of the clamping seat are respectively provided with upwardly protruding docking protrusions, and when the clamping seat is rotated to the top of the jig under the drive of the rocker arm, the docking protrusions are embedded in the docking holes of the jig to position and fix the clamping seat, thereby ensuring that the relay coil is accurately placed in the material groove of the jig. Furthermore, clamping holes are horizontally provided on the left and right sides of the clamping trough, which pass through the side walls of the clamping seat and are connected to the clamping trough. A clamping block is slidably inserted into the clamping hole, and the cap body at the outer end of the clamping block is connected to the external seat arranged on the outside of the clamping seat through a horizontally arranged clamping spring, and the clamping block is driven to move toward the clamping trough by the elastic force of the clamping spring so as to elastically and adaptively clamp the relay coil fixed in the clamping trough; when the rocker arm drives the clamping head to move above the jig and places the relay coil into the material trough of the jig, the gap space between the clamping block of the clamping head and the clamping seat is correspondingly nested in the positioning plate of the clamping limit assembly, and as it descends, the positioning plate pushes the clamping block outward, so that the clamping block places the relay coil and releases the relay coil at the same time.

[0058] Furthermore, the pressing mechanism of the present invention adopts a movement method of pressing the material in the direction of a Z-shaped path so as to press the relay coil on the jig into the relay hook. This pressing method can effectively avoid interference with the movement of the transfer feeding mechanism during the pressing process; the special feature is that the pressing mechanism of the present invention drives the pressing piece to complete the pressing action of the relay coil in the direction of a Z-shaped path, which is achieved only by a single power drive in the vertical direction output by 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 thereto by the horizontal guide rail to descend synchronously. When the adjusting slide drives the pressing piece to move downward, it is nested in the inclined guide groove opened on the side pressing guide plate through the roller and moves along the inclined guide groove. The inclined guide groove extending along the Z shape provides a reaction force to the adjusting slide through the roller, so that the adjusting slide moves in the vertical direction while moving horizontally along the guide rail. The sliding connection between the adjusting slide and the guide rail is used to avoid interference in the movement when the adjusting slide drives the pressing piece to press in the Z-shaped path.
