The pin module 210 is installed on the first upper plate 202 on the basis of the side position of the first work table and individually receives the pins 60 stacked inside the pin drop guide 213, And a pin insert block (214) for guiding the direction of the pin insertion hole to coincide with the pin hole of the shaft connecting pipe of the hinge body.

The pin insert block 214 is formed to have a block shaped body 214a fixed to the first upper plate 202 and through both side surfaces of the body 214a in front of the upper surface 214c of the body 214a. And a pin mounting groove 214b for opening the upper portion of the groove. Here, the pin mounting groove 214b has a U-shaped cross-sectional shape corresponding to the diameter of the fin 60. [ The height direction position and groove extending direction of the pin mounting groove 214b are designed to correspond to the position of the shaft connecting pipe of the hinge body and the direction of the pin hole. In addition, the upper surface 214c of the body 214a of the pin insert block 214 is made of a very smooth surface, such as a surface plate, so that it can be used as a sliding guide surface.

The pin insert block 214 includes a connecting seat portion 214d that protrudes upward from both rear positions of the upper surface 214c of its body 214a by the same height.

Here, the protruding height of the connecting seat portion 214d may be determined by the size of the pin 60 and the sliding movement of the pin 60 plus the clearance size based on the upper surface 214c.

That is, when the pins 60 stacked inside the pin drop guide 213 separate and stop on the upper surface 214c of the pin insert block 214, Drop guide 213 in a similar manner to the state shown in Fig.

The pin insert block 214 includes a cylinder mount 214e protruding in the back direction of the body 214a while maintaining the same level as the upper surface 214c of the body 214a.

The pin module 210 is installed and supported on the cylinder mount 214e of the pin insert block 214 and has a pin feed actuator 216 for reciprocating the pin coupled to the end of the actuating arm of the actuator .

Here, the pin movable plate 215 is provided with a pin fixing guide hole 215a having a cross section of the upper light beam cross section. According to the change of the position of the pin movable plate 215, the pin fixed position guide hole 215a can be positively positioned (for example, self-centering) at the lower portion of the pin drop guide 213. [ In this case, the pin 60 can move downward (e.g., drop) by its own weight.

The pin 60 dropped from the pin drop guide 213 can be positioned in the pinion position guide hole 215a of the pin plate 215 and the pin can be moved in correspondence with the movement (e.g., advancement) of the copper plate 215 To the upper portion of the pin mounting groove 214b of the pin insert block 214 and then to the pin mounting groove 214b by its own weight again.

The pin module 210 includes a pin insertion actuator 217 provided on the first upper plate 202 with reference to the extension direction of the pin attachment groove 214b, (218).

Here, the push block 218 protrudes along the operating direction of the pin inserting actuator 217 and is seated in the pin mounting recess 214b at the bottom middle position of the push block 218, and the pin 60 is inserted into the pin hole of the shaft connecting pipe of the hinge body A tip portion 218a is formed.

The cylinder body of the pin insertion actuator 217 can be fixed to the first upper plate 202 through the plurality of support plates 219. By adjusting the height of the support plate 219, The height of the tip portion 218a can be adjusted.

When the operation of the pin module 210 is started, the original pin 60 is transferred to the inside of the pin chute 212 and the pin drop guide 213 by the pin feeder 211. The pin 60 reaches the pinned position guide hole 215a of the moving plate 215 slidably disposed on the upper surface 214c of the pin insert block 214. [ In addition, according to the forward movement of the pin feed actuator 216, the moving plate 215 is moved forward, but the pin 60 is restricted by the pin position guide hole 215a and can not escape to another place. As a result, the pin 60 reaches the upper portion of the pin mounting groove 214b of the pin insert block 214 at the stopping point of the moving plate 215, and is loaded into the pin mounting groove 214b by its own weight .

Thereafter, when the pinion position guide hole 215a comes to coincide with the bottom surface exit of the pin drop guide 213 after the moving plate 215 is moved backward in accordance with the backward operation of the pin supply actuator 216, 215 is stopped. At this time, another pin (60) mounted on the pin drop guide (213) is again mounted on the pin fixed position guide hole (215a) of the moving plate (215).

In this manner, each pin 60 can be repeatedly prepared to be individually loaded into the pin mounting groove 214b of the pin insert block 241. [

On the other hand, when one pin (60) is loaded in the pin mounting groove (214b) and the moving plate (215) is moved backward, the pin insertion actuator (217) becomes operable.

That is, even if the push block 218 of the pin insertion actuator 217 is moved, interference with the moving plate 215 in the backward state is prevented.

Further, the push block 218 and the tip portion 218a are advanced by the forward movement of the pin insertion actuator 217 to transfer the pushing force for the pin insertion to the pin 60. [

The pin 60 is inserted or assembled into the pinhole of the washer and the shaft connecting pipe of the hinge body which is finally positioned in the first work table while moving along the pin mounting groove 214b by the pushing force.

Further, when the pin insertion or pin assembly is completed, the reverse operation of the pin insertion actuator 217 is performed, and the push block 218 and the tip portion 218a are returned. That is, it does not interfere with advancement of the moving plate 215 for loading the new pin 60 into the pin mounting groove 214b.

The operation of this pin module 210 may be accomplished after each washer is positioned in the incision groove of the axially connecting tube of the hinged main body, respectively, after the hinge body is positioned in the first work table, as described below.

The pin module 210 provides the pin drop guide 213, the moving plate 215 and the pin fixed position guide hole 215a as the pin 60 moving and restricting means to restrict the movement to the power stopper or the supply object There is an advantage that it is not necessary to separately provide means for releasing or releasing.

Referring to FIG. 7, the hinge body module 230 serves to supply the hinge body 80 to the first work table 204 for assembling with the pin 60.

For example, the hinge main body module 230 is disposed in the upper space of the first upper plate 202 based on the position where the hinge body 80 is fed from the hinge body feed conveyor (not shown) of the transport apparatus, And a main chute 231 forming a supply path of the main chute 231.

The main chute 231 includes a tuck type connecting portion 231a which is bent in a vertical direction and bent at the other end which is downwardly extended from the one end side of the chute bottom side and both side wall surfaces in a downward slanting direction do.

Two stop holes 231b and 231c are formed on the floor of the chute, spaced along the extending direction of the chute floor, with respect to the upper position of the main chute 231.

The hinge body module 230 includes a body drop guide 232 for guiding the supply of the hinge body via the body chute 231.

The body drop guide 232 connects the upper portion of the drop guide to the single jaw connecting portion 231a of the main body chute 231 so that the inner space of the drop guide is aligned with the main body mounting groove 204b of the first work table 204 , And the bottom of the drop guide is connected to the upper surface of the first work table (204).

The hinge main body module 230 movably inserts the stopper heads 233a and 234a in the stop holes 231b and 231c on the bottom of the chute of the main body chute 231 and is stopped by the stopper brackets 233b and 234b And a first body stopper 233 and a second body stopper 234 which are supported on both side walls of the main body chute 231.

The control unit (not shown) controls supply or stop of the hinge body 80 by sequentially controlling the operation of the first body stopper 233 and the second body stopper 234 in accordance with the control or hinge body supply sequence Can be performed.

For example, the control unit selectively or sequentially controls the operation of the first body stopper 233 and the second body stopper 234 so that each of the stopper heads 233a and 234a is protruded or protruded from the stop holes 231b and 231c . In other words, the hinge main body 80 can be controlled so as not to be blocked by the stopper heads 233a and 234a protruding from the stop holes 231b and 231c.

The control unit controls the positions of the respective stopper heads 233a and 234a to maintain the same level with respect to the stop holes 231b and 231c so that the first and second main stoppers 233 and 234 do not protrude, The hinge main body 80 can be controlled to be supplied to the body drop guide 232 through each of the stop holes 231b and 231c.

The hinge main body module 230 movably inserts the stopper head 235a in the front opening portion 232a of the body drop guide 232 and the stopper brackets 233b and 235b are provided on both sides of the body drop guide 232 And a third body stopper 235 supported on the wall surface. Here, the front opening 232a is spatially connected to the inner space of the body drop guide 232. The inner space of the body drop guide 232 may be a space through which the hinge body 80 passes.

The control unit also controls the operation of the third body stopper 235. [

The hinge main body 80 released from the stopper head of the second main body stopper 234 is moved to the main mounting groove 204b of the first work table 204 before being dropped or positively moved (For example, the stopper head 235a is moved back) in accordance with a predetermined timing after the stopper 235 of the main body stopper 235 is stopped (E.g., loaded) in the main body mounting groove 204b of the work table 204. [

That is, the sequential operation control of the plurality of main body stoppers 233, 234, and 235 sequentially controls the plurality of hinge bodies 80 along the main body chute 231 to individually attach the main body mounting grooves 204b of the first work table 204, Lt; / RTI >

The main body drop guide 232 includes front side end portions 232b spaced apart from each other with respect to the front opening portion 232a and side wall surfaces 232c extending toward the back side from the both side end portions 232b, And a back surface 232d connected to each other at the back of both side wall surfaces 232c.

The body drop guide 232 corresponds to the lower right corner of the body drop guide 232 so as to discharge the first assembly 80a (see FIG. 1) after assembly is completed in the lateral direction of the body drop guide 232 And includes a fitting portion 232e that is formed as a portion of the front side ends 232b, both side walls 232c,

That is, the segment portion 251 of the first ejector 250 may also be a component for holding and opening the hinge body having a Hangul diagonal cross-sectional shape formed corresponding to the height and cross-sectional shape of the fitting portion 232e.

For example, when the segment portion 251 is fitted to the fitting portion 232e of the body drop guide 232, the segment portion 251 can maintain the stop state based on the stopping force of the discharge actuator 254, The portion below the inner side surface of the segment portion 251 may be in surface contact with the outer side of the shaft connecting pipe of the hinge body 80 to generate a supporting force.

That is, the washer can be positively positioned in the cutting groove 83 of the shaft connecting tube of the hinge body 80 by the washer module described later. When the pin 60 is inserted into the pinhole of the shaft connecting pipe of the hinge body 80 having the washer by the pin module 210, the portion beneath the inner side of the segment 251, And is not pushed in the inserting direction of the pin 60 by the insertion force of the pin 60.

The main body drop guide 232 can be detachably coupled to the upper surface of the first work table 204 through a flange portion 232f protruding forward from the bottom of the front end portions 232b.

The inner space of the body drop guide 232 may be a space capable of moving the hinge body 80 in the vertical direction and the segment 251 of the first ejector 250 may be a space for moving the body drop guide 232, The hinge body 80 can be a space that can be restrained or supported so as not to move in the plane direction of the first upper plate 202 when the hinge body 80 is shaped and coupled to the fitting portion 232e of the first upper plate 202. [

The first work table 204 includes an assembly die 204a fixed to the first upper plate 202 and a pair of side plates 204b formed to penetrate both side surfaces of the assembly die 204a from the front side of the upper surface 204c of the assembly die 204a. And a main body mounting groove 204b which opens the upper portion of the groove. Here, the main body mounting groove 204b has a U-shaped cross-sectional shape corresponding to the outer diameter of the shaft connecting pipe of the hinge body 80. [ The height direction position and the groove extending direction of the main body mounting groove 204b can be determined in consideration of the pin or the above-mentioned pin module to be coupled to the shaft connecting pipe of the hinge body. For example, the axis of the main body mounting groove 204b of the first work table 204 is exactly aligned with the axis of the pin mounting groove 214b of the pin insert block 214 described above with reference to FIG.

The top surface 204c of the assembly die 204a of the first work table 204 is also very smooth or very smooth so that it can be used as the sliding guide surface of the segment 251 of the first ejector 250 Surface.

The first assembly 80a in a state of being away from the assembly chute 311 can be placed on the upper surface of the pair of inner rails 304a and at this time the end of the pusher portion 304b located between the inner rails 304a The side surface of the jaw portion 304c is brought into contact with the outside of the shaft connecting pipe 85 of the first assembly 80a.

The assembly supply module 310 is supported on the second upper plate 302 and connects the pusher portion 304b with an actuating arm so that the pusher portion 304b, the stepped portion 304c and the first assembly 80a, And an assembly loading actuator 315 for pushing and loading toward the stop block 351 of the actuator 350.

In this case, the door fastening plate and the paper stop plate portion of the first assembly 80a are fitted into the inner space of the stop block 351, while the shaft connecting pipe 84 of the first assembly 80a is inserted into the stop block 351, Exposed to the outside of the housing 351.

The first assembly 80a is restrained by the stop block 351 and the step portion 304c on the upper surface of the inner rail 304a of the second work table 304 so that the first assembly 80a can not be moved horizontally or vertically Or it may be in a positively positioned state.

The assembly supply module 310 also includes a pair of assembly moving guide plates (not shown) disposed outside the inner rail 304a (e.g., on the outer side of each inner rail) (316).

The assembly moving guide plate 316 is provided with an inclined guide surface 316a at an upper portion of the side surfaces facing each other on the basis of a position corresponding to the moving height of the first assembly 80a (for example, the height of the inner rail 304a) Respectively.

The first assembly 80a in motion can contact the inclined guide surface 316a of each of the assembly moving guide plates 316. [

Through the above contact, the assembly moving guide plate 316 serves not only to prevent the first assembly 80a from separating out of the inner rail 304a, but also to prevent the center of the first assembly 80a from moving to the inner rail And the center line MCL between the guide portions 304a and 304a.

Since the rivet supply module 320 is arranged to face the first assembly 80a at one side position and the other side position, the rivet supply module 320 will be described with reference to any one of the two rivet supply modules 320 for ease of explanation do. In addition, among the constituent elements described below, reference numerals for paired elements in the drawings can be understood to refer to a pair of corresponding constituent elements, even if they indicate only one of the constituent elements.

The rivet supply module 320 includes the rivet guide portion 321 shown in Figs. 13 and 14, the variable jig 324 shown in Fig. 15, the pushing shaft portion 328 and the rivet inserting actuator 327).

13, the rivet guide portion 321 serves to guide the supply of the rivets 50 so that the rivets 50 conveyed through the rivet chute are individually supplied along the vertical direction.

For example, the rivet guide portion 321 has a rivet guide (not shown) having a rivet supply path 321a of a shape corresponding to the end surface of the rivet 50 so that the rivet 50 delivered through the rivet chute falls vertically 321b. Here, the bottom of the rivet drop guide 321b is provided with a wing portion 321e which is a flange structure protruding outward from both sides of the rivet drop guide 321b and having a long hole to be engaged with the upper surface of the jig body of the variable jig by bolt fastening ).

The worker can easily adjust the mutual engagement position between the upper surface of the jig body of the variable jig and the rivet drop guide 321b by using the slots and bolts of the wing portion 321e.

The rivet supply path 321a may be a rivet moving path passing through the upper and lower surfaces of the rivet drop guide 321b along the vertical direction of the rivet drop guide 321b.

The side portions of the rivet supply path 321a facing each other in the respective rivet guide portions 321 are opened toward the first assembly.

The rivet guide portion 321 has a flange portion at a bottom portion thereof and is configured to be coupled to the upper surface of the variable jig 324. [

The rivet guide portion 321 has a first rivet stopper 322 and a second rivet stopper 323 provided on both outer wall surfaces of the rivet drop guide 321b.

Here, the first rivet stopper 322 and the second rivet stopper 323 each have an operation arm operated in a solenoid valve manner, and each of the operation arms has rivet stop pins 322a and 323a at the ends thereof.

Each of the first rivet stopper 322 and the second rivet stopper 323 includes a holder 322b and a holder 323b and may be installed and fixed to both outer wall surfaces of the rivet drop guide 321b.

In particular, the installation height of the first rivet stopper 322 and the second rivet stopper 323 is designed to be different on the outer wall surfaces of both sides of the rivet drop guide 321b with respect to the rivet drop guide 321b.

14, the installation height of the second rivet stopper 323 provided on the right outer wall surface of the rivet drop guide 321b is smaller than the installation height of the second rivet stopper 323 provided on the left outer wall surface of the rivet drop guide 321b, Is relatively high.

At this time, the vertical distance between the rivet stop pins 322a and 323a may be equal to the sum of the rivet clearance and the diameter of the rivet stop pin 322a.

The stop pin holes 321c and 321d are formed in the rivet 50 so as to pass through the rivet supply path 321a with reference to positions corresponding to the first rivet stopper 322 and the second rivet stopper 323, And is formed on both outer walls of the rivet drop guide 321b corresponding to the portion where the shaft portion passes.

Each of the rivet stop pins 322a and 323a passes through each of the stop pin holes 321c and 321d and is driven by a forward force or a backward force transmitted from the operation arm of the first rivet stopper 322 or the second rivet stopper 323 And is inserted movably in each of the stop pin holes 321c and 321d.

The control unit (not shown) controls the operation of the first rivet stopper 322 and the second rivet stopper 323 in accordance with the sequential control or rivet supply sequence so that each rivet stop pin 322a, It is possible to perform the supply control or the stop control of the rivet 50 in response to the protruding and retracting operation of the rivet 321c and 321d.

In particular, the rivet 50 comprises a rivet head portion having a relatively large diameter and a rivet shaft portion protruding from the center of the rivet head portion. Therefore, along the longitudinal direction of the rivet 50, the shapes of the rivet shaft portion and the rivet head portion are asymmetric with respect to each other. Therefore, when feeding or feeding such a rivet 50, careful supply control is required so that the rivets 50 do not tangle.

The present embodiment performs the supply control of the rivet 50 individually or sequentially using the first rivet stopper 322 and the second rivet stopper 323 so that the rivet 50 stacked along the rivet supply path 321a Can be safely dropped into the guide tunnel of the jig body of the variable jig to be described later individually without being tangled with each other.

15, the rivet supply module 320 may have a elliptical shape with respect to the direction in which the first assembly 80a is supplied (e.g., Y-axis direction) with respect to the second work table 304 of the rivet assembler 300 And a variable jig 324 installed on the second upper plate 302 so as to be disposed along the direction (for example, the X-axis direction).

The variable jig 324 has a jig body 324a fixed to the second upper plate 302 and a jig body 324b fixed to the second upper plate 302 in the rivet inserting direction A guide tunnel 324c formed on the upper portion of the jig body 324a along the X-axis direction of the jig body 324a and an upper portion of the front side of the jig body 324a facing the axial coupling pipe of the first assembly 80a And a hinge portion 324b that forms a T-shaped space with a planar reference with the guide tunnel 324c.

12 or 17, the pushing shaft portion 328 has a cross section corresponding to the guide tunnel 324c of the jig body 324a, and is movably inserted in the guide tunnel 324c.

The pushing shaft portion 328 has a head seating portion 328b which is formed on the front end of the pushing shaft portion 328 to seat the rivet head portion of the rivet 50 and a head seating portion 328b relatively to the head seating portion 328b And a triangular end portion 328a formed at the lower end of the front end of the pushing shaft portion 328 with a rounded curved surface.

The rear end of the pushing shaft portion 328 is connected to the operation arm of the rivet insertion actuator 327.

The pushing shaft portion 328 can be moved within the guide tunnel 324c of the jig body 324a by movement (e.g., forward or backward) of the actuating arm of the rivet inserting actuator 327. [

The rivet insertion actuator 327 is installed on the second upper plate 102 and generates a force necessary for moving the pushing shaft portion 328.

The variable jig 324 includes a pair of movable pieces 325 that are hinged to the hinge portion 324b and return to their original positions after being rotated by the restoring spring 326 as a double door type door structure.

A spring installation space 325d for installing a restoration spring 326 is formed in each movable piece 325. A hinge hole through which the hinge bolt 329 can be fastened is formed at the upper and lower portions of the spring installation space 325d Respectively.

The hinge hole of each movable piece 325 is formed to coincide with the hinge hole of the hinge portion 324b of the jig body 324a.

Each restoring spring 326 is engaged to enclose the hinge bolt 329 in a state of being located in the spring installation space 325d of each movable piece 325.

Each of the restoring springs 326 is a kind of torsion spring and one end of each of the end portions of the restoring spring 326 is connected to the end seating groove 325c of each movable piece 325, May be supported on the surface of the jig body 324a. A spring insertion hole (not shown) is formed on the surface of the jig body 324a in the vicinity of the hinge portion 324b for holding the other end of the restoring spring 326 therebetween .

The variable jigs 324 are formed at the upper corner of the end of each of the movable pieces 325 with respect to a position where the movable pieces 325 are opposed to each other and have a curved seating portion 325b for supporting the rivet shaft portion of the rivet 50 ).

The variable jig 324 includes a sliding contact surface 325a formed at a lower corner of the end of each of the movable pieces 325 with reference to a lower position of each curved seating portion 325b.

Here, the sliding contact surface 325a of each movable piece 325 is in contact with the triangular end portion 328a of the pushing shaft portion 328 (see Fig. 12).

The triangular end portion 328a is in a sliding-acting relationship with respect to the sliding contact surface 325a.

16, the rivet inserting actuator 327 performs the advancing operation so that the rivet 50 will not fall downward from the movable piece 325 due to the own weight of the rivet 50 Thereby advancing the pushing shaft portion 328 at a high speed.

The pushing shaft portion 328 having the triangular end portion 328a is quickly advanced by the rivet inserting actuator 327 to linearly move (e.g., advance) along the guide tunnel 324c of the jig body 324a do.

In this process, the triangular end portion 328a of the pushing shaft portion 328 is brought into contact with the sliding contact surface 325a of the movable piece 325 before the rivet 50. The triangular end portion 328a of the pushing shaft portion 328 can push out the sliding contact surface 325a of the movable piece 325 in accordance with the advancement of the pushing shaft portion 328. As a result, The movable piece 325 in the hinged state can be opened while being rotated.

The rotational opening angle at which the two movable pieces 325 simultaneously rotate away from each other is such that the rivet head of the relatively large rivet 50 is not in contact with the curved seating portion 325b of the movable piece 325 Can be determined within the range of rotation.

Since a part of the surface of the curved seating portion 325b of the movable piece 325 can be brought into contact with the lower surface of the rivet shaft portion of the rivet 50 when the pair of movable pieces 325 are partially opened at the same time as the rotation The insertion direction of the rivet 50 can be guided by the curved seating portion 325b of the movable piece 325. [

The rivet shaft portion of the rivet 50 is not brought into contact with the curved seating portion 325b of the movable piece 325 or the rivet head portion of the rivet 50 is not brought into contact with the curved seating portion 325b It may be instantaneously in a state in which it is not in contact with the first electrode 325b. However, since the rivet 50 receives the inertial force resulting from the advancement of the pushing shaft portion 328, it can be moved directly toward the pinhole of the shaft coupling pipe of the first assembly. That is, the insertion force generated by the forward movement of the pushing shaft portion 328 is transmitted to the rivet 50, and the rivet shaft portion of the rivet 50 which receives this insertion force is eventually inserted into the pin hole of the shaft coupling pipe of the first assembly .

At this time, the diameter of the rivet shaft portion of the rivet 50 is relatively larger than the inner diameter of the pin hole of the shaft connecting pipe of the first assembly, so that the rivet shaft portion and the shaft connecting pipe can be physically fixed.

On the other hand, when the pushing shaft portion 328 is retracted and retracted, the opened movable piece 325 is reversely rotated by the elastic force of the restoring spring 326 to return to its original position (e.g., closed) (I.e., return to the initial state).

Referring to FIG. 16, as described above, the two movable pieces 325 facing each other can stably support the rivet 50 through the curved seating portion 325b.

For example, in the rivet 50, the rivet shaft portion and the rivet head portion have different diameters. At this time, the circumferential surface of the rivet shaft portion of the rivet (50) is seated in the curved seating portion (325b) of the movable piece (325).

The rivet head portion of the rivet 50 is seated in the head seating portion 328b of the pushing shaft portion 328 to be positioned in the space on the back side of the curved seating portion 325b of the movable piece 325. [

Particularly, since the triangular end portion 328a is positioned farther forward than the position of the head seating portion 328b along the longitudinal direction (e.g., the X-axis direction) of the pushing shaft portion 328, the triangular end portion 328a, The rivet head portion of the rivet 50 seated on the head seating portion 328b does not contact the movable piece 325 even if it moves together with the pushing shaft portion 328 And may be supplied only toward the pinhole of the shaft connector of the first assembly 80a located in the second workbench 304. [

Referring to FIGS. 11 and 12, the rivet supply module 320 symmetrically arranged as opposed to the first assembly 80a faces the first assembly 80a at the same time, (For example, a rivet inserting operation) such that it is inserted into the shaft connecting pipe of the motor.

At this time, the doorframes of the first assembly 80a and the stationary plate stopper portions are fitted in the inner space of the stop block 351. After the advancing operation of the assembly loading actuator 315, the assembly loading actuator 315 pushes the pusher portion 304b and the step portion 304c remain stationary. As a result, the door fastening plate and the door top plate portion of the first assembly 80a can be temporarily held by the step portion 304c and the stop block 351.

Therefore, the rivet shaft portion of the rivet 50 is rigidly and precisely assembled as if it is stuck in the shaft connecting pipe of the first assembly 80a, so that it is finally made into the second assembly 80b.

11 and 12, the second ejector 350 is installed on the second upper plate 302 at a position opposite to where the assembly supply module 310 is located in the Y axis direction with respect to the second work table 304 do. The second ejector 350 serves to separate the second assembly 80b (see FIG. 1) from the second workbench 304 and take it out of the second drop hole 303 of the riveting machine 300 I am responsible.

At this time, the second ejector 350 may use an adhesive force (e.g., magnetic force by the second electromagnet).

For example, the second ejector 350 includes two outer rails 352 installed on the second top plate 302 with respect to the periphery of the second drop hole 303.

The second ejector 350 also has a sliding wing 351a slidably coupled between the outer rails 352 and is mounted on the outer rail 352 after the first assembly 80a or rivet 50 is assembled And a stop block 351 having a seating space capable of receiving a door stopper plate and a door stop plate of the second assembly 80b and having a second electromagnet 351b above the seating space.

The second ejector 350 connects the actuating arm to the stop block 351 and the second ejection actuator 353 supported by the second upper plate 302 corresponding to the periphery of the second drop hole 303 .

The stop block 351 of the second ejector 350 is not only a means for positively positioning the first assembly 80a during the assembly of the rivets 50 but also allows the rivets 50 to be assembled to the second assembly 80a, When the second assembly 80b (see Fig. 1) is made and the second electromagnet 351b applies a magnetic force to the second assembly 80b and then the second ejection actuator 353 is operated backward, The assembly 80b may be separated from the second work table 304 and moved to an upper position of the second drop hole 303. [

When the power applied to the second electromagnet 351b is cut off, the second assembly 80b is separated from the stop block 351 and discharged toward the second drop hole 303. [

The second assembly 80b thus discharged can be conveyed or supplied to the press separator 400 shown in FIG. 1 by the second conveyor belt 92 for unloading. Here, the second conveyor belt 92 for unloading may extend to a press-mold insertion port (not shown) for forming a slit of the press separator 400.

In the hinge manufacturing apparatus according to the present invention, the connecting bar is integrally formed between the shaft connecting pipes on the door frame fixing plate, and the two shaft connecting pipes of the door frame fixing plate are fixed with respect to the one shaft connecting pipe of the door fixing plate It is possible to produce a durable product that does not spread outwardly in the direction of being separated from each other through an automated process.

In the hinge manufacturing apparatus according to the present invention, a slit is further formed by a press separator without separately manufacturing a door frame fixing plate and a door upper plate, and the door fixing plate and the door upper plate are rotatably separated to be a hinged product Therefore, it is possible to reduce the manufacturing cost and manufacturing time by omitting the process of assembling and assembling the door frame fixing plate and the door fixing plate in the existing technology, and it is possible to reduce the manufacturing cost and the rotation time between the door frame fixing plate and the door fixing plate It is possible to mass-produce high-quality hinge products that can be easily and precisely matched.
