Description

Riveting device and riveting method

The present invention relates to a rivet supply unit for supplying rivets to a rivet gun for riveting, and to a riveting device and a riveting method.

In general, riveting (riveting) is a method of fastening two or more mutually laminated plate materials using a rivet, and has an easy operation and excellent strength of the fastening part. Rivets are used in various forms. For example, in the case of a blind rivet, the head of the rivet body is riveted by inserting the rivet body into the rivet hole of the plate in a state in which a shank with a wide end is temporarily coupled to the tubular rivet body. If the shank is removed abruptly after being caught in the hole, the opposite end of the rivet body expands and the plate is fastened in such a way that the locking part is formed. Such a blind rivet is known as one of the rivets that can perform the riveting operation simply and efficiently. On the other hand, a rivet gun may be used for riveting the blind rivet to the plate. In this case, the operator loads the blind rivet into the rivet gun and then operates the rivet gun to rivet the blind rivet to the plate. However, according to the prior art, the operator has the inconvenience of having to pick up the blind rivets placed in various directions by hand and load them into the rivet gun to perform the riveting operation. Therefore, there is a need for a device capable of increasing work efficiency by automatically supplying blind rivets to the rivet gun.

1 is a schematic diagram illustrating a riveting device 10 including a rivet gun 100 and a rivet supply unit 200 according to an embodiment of the present invention.

Referring to FIG. 1 , the riveting device 10 includes a control unit 300 , a rivet gun 100 , and a rivet supply unit 200 . The rivet gun 100 and the rivet supply unit 200 are connected to each other, such as an electrical connection, so that driving can be interlocked. Of course, the connection is not limited to the electrical connection and may be connected to each other by various means for transmitting power. For example, power may be transmitted through the hydraulic pressure supply line 105 for the transmission of hydraulic pressure, and movement of a configuration such as a rivet (1 in FIG. 3 ) may be made. In addition, the rivet supply unit 200 may be connected to the control unit 300 , constrain various conditions for continuous riveting of the riveting device 10 , and control the rivet gun 100 and the rivet supply unit 200 under the conditions can do. A detailed description related to the control of the control unit 300 will be described later with reference to FIG. 8 , and the rivet gun 100 and the rivet supply unit 200 according to an embodiment of the present invention will be sequentially described below.

2 is an exploded perspective view of the rivet gun 100 according to an embodiment of the present invention.

Referring to FIG. 2 , the rivet gun 100 includes a finger unit 110 to which the rivet 1 discharged from the rivet supply unit 200 is delivered, a cylinder 130 for moving the finger unit 110 forward or backward, and a finger unit. a head portion 104a from which a rivet 1 is provided.

Specifically, the body side of the rivet gun 100 extends laterally from the head portion 104a, the first body portion 102 including the power generating portion for drawing out the shank of the rivet 1, and the first body portion 102 It may include a holding part 101 and a second body part 103 provided at one end of the holding part 101 . Here, the gripper 101 may be provided with a switch, which is operated by a user and when the switch is turned on, the shank of the rivet 1 is drawn out toward the first body portion 102 to perform the rivet 1 . can

On the other hand, the finger portion 110 is connected to the cylinder 130, is moved to the front side of the head portion 104a by the advancement of the cylinder 130, and the end of the head portion 104a by the retraction of the cylinder 130. It may be located on the rear side as a reference. The advancing and retracting of the cylinder 130 causes the overlapping guide 150 to unfold in a forward direction and to overlap again. Also, the sensor unit 140 may be moved by the forward and backward movement of the cylinder 130 . The sensor unit 140 may detect the forward and backward states by sensing a contact or sensing a distance. For example, the sensor unit 140 may be a proximity sensor, and by disposing a configuration that is sensed by the sensor unit 140 when moving forward or retreating, detects the forward or backward movement of the cylinder 130 according to whether the proximity is detected. it can be done

And, when the cylinder 130 is advanced, the rivet 1 discharged from the rivet supply unit 200 may be transferred to the finger unit 110 . The transfer here means transfer that is provided automatically and periodically. For example, the transfer may be a transfer in which the rivet 1 set in the rivet supply unit 200 is discharged as hydraulic pressure is generated. Of course, the present invention is not limited thereto. However, in this example, it will be explained through an example of discharge by the generation of pressure, and in this case, a flexible tube may be connected to the rivet supply unit 200 and the finger unit 110 to be transported within the tube.

The rivet 1 transferred to the finger unit 110 may be gripped by the finger unit 110 . In a state in which the rivet 1 is gripped by the finger portion 110 , the center of the head portion 104a and the center of the rivet 1 (the insertion hole of the rivet shank) may be located on the same axis. As the cylinder 130 is retracted by this arrangement, the finger unit 110 is retracted and the rivet 1 can be supplied to the head unit 104a. Of course, the supply here may be in a direction such that the head of the rivet 1 is exposed to the outside of the head portion 104a and the shank is retracted into the head portion 104a.

In addition, the retracted state at the time of supplying the rivet 1 to the head part 104a is not the maximum retracted state during the movement section, but is retracted by a predetermined distance from the maximum advanced state, and the rivet 1 is moved to the head portion 104a. ) after supplying the finger portion 110 can be retracted to the maximum. In the process in which the finger unit 110 is retracted to the maximum, the spacer 120 may intervene to retract the finger unit 110 and space the detailed components of the finger unit 110 at the same time. More precisely, the finger part 110 may be moved in the retracting direction while being spread by the spacer part 120 . The head part 104a may be located in the space where the finger part 110 is widened when retracting to the maximum.

Riveting may be repeatedly performed through the above-described configuration, which means that a predetermined cycle is applied.

3 is a view showing the side of the finger part 110 according to an embodiment of the present invention. b) is a view showing a state in which the rivet 1 is supplied to the head portion 104a by the finger portion 110 .

Referring to FIG. 3( a ), the finger part 110 includes a first finger 111 , a second finger 112 , a position correction part 113 , an induction part 113a , a connection part 115 , a roller 116a, 117a) may include a first roller portion 116 and a second roller portion 117 and a supply pipe 119 each including. In order for the rivet 1 to be provided as the finger part 110 , the supply pipe 119 may be connected to a flexible pipe (not shown), which is an example described above. When the discharged rivet 1 is delivered to the finger unit 110 through the supply pipe 119 , the rivet 1 may be positioned at a position held by the finger unit 110 . Here, the gripped position is to be disposed between the first finger 111 and the second finger 112, and the first finger so that the disposed rivet 1 is positioned at the center of the head portion 104a on the extension line of the shank. A 111 and a second finger 112 may be positioned.

In addition, since the reciprocating rod 132 is withdrawn from the body 131 of the cylinder 130, the finger portion 110 connected to the reciprocating rod 132 may be in an advanced state according to the withdrawal of the reciprocating rod 132. , the advanced state may be a maximally advanced state.

Referring to FIG. 3(b), after the rivet 1 is delivered as described above, the finger part 110 may be retracted by a predetermined distance to supply the rivet 1 to the head part 104a. At this time, the cylinder 130 may retract the reciprocating rod 132 from the body 131 in order to retract the finger 110 by the predetermined distance. Here, the reciprocating rod 132 is advanced to provide the rivet 1 to the finger portion 110, and the reciprocating rod 132 is drawn in a predetermined distance to supply the received rivet 1 to the head portion 104a by a predetermined distance. The rivet supply to the head part 104a is made at a specific point in the process of repeatedly performing the maximally advanced state and the maximally retreated state, rather than having a separate moment of stopping in the retracted state.

4 is a view showing a state when the finger unit 110 is advanced and retracted according to an embodiment of the present invention. FIG. 4 (a) is a view showing a state in which the finger unit 110 is retracted 4(b) is a diagram illustrating a state in which the finger unit 110 is advanced.

Referring to Figures 4 (a) and 4 (b), the reciprocating rod 132 of the cylinder 130 is retracted to the maximum and shows the finger portion 110 in a state that is drawn into the body 131, the spaced portion The finger unit 110 may be in a state in which the first finger 111 and the second finger 112 are spaced apart from each other by reference numeral 120 .

Specifically, the reciprocating rod 132 of the cylinder 130 may be directly connected to the connection part 115, and each of the first roller part 116 and the second roller part 117 through the connection part 115 is a reciprocating rod ( 132) can be connected. In addition, the first roller part 116 and the first finger 111 may be connected, and the second roller part 117 and the second finger 112 may be connected. That is, when the connecting portion 115 is advanced or retracted by the advance or retraction of the reciprocating rod 132, the finger portion 110 indirectly connected to the reciprocating rod 132 through the connecting portion 115 may be advanced or retracted. .

In addition, the first roller part 116 and the second roller part 117 may be connected to the connection part 115 so as to be able to rotate, and the first roller part 116 and the second roller part 117 are retracted by the reciprocating rod 132 . The roller parts 117 are spaced apart from each other and may rotate around a connection point connected to the connection part 115 . In this case, the rotating directions may be opposite to each other and spaced apart from each other. Here, by making the rotation directions of the first roller part 116 and the second roller part 117 opposite to be spaced apart from each other, it is a space formed between the first finger 111 and the second finger 112 and the head part 104a. can be located. For this reason, when retracting, the finger part 110 is located behind the head part 104a. Since the head portion 104a is located in front of the finger portion 110, it becomes easier to perform riveting toward the riveting object.

Furthermore, it is due to the spacer 120 that the rotation direction is made different from each other. Specifically, the spacer 120 includes a tip 121 protruding toward the direction in which the cylinder 130 is advanced. The tip portion 121 is matched to face the intermediate position between the first roller portion 116 and the second roller portion 117 so that the first roller portion 116 and the finger portion 110 are moved to the retracted state. The rollers 116a and 117a of the second roller part 117 may be divided into both sides by the tip part 121 and moved in a retracted direction. Accordingly, the first roller part 116 and the second roller part 117 may be spread apart by the thickness of the spaced part 120 from the tip part 121 in the retreating process. Since one end is fixedly connected to the connection part 115 so as to be rotatable and the other end is a free end that is not fixed, the connection point connected to the connection part 115 can be rotated to the center of rotation in the retraction process.

More specifically, in the process in which the finger part 110 is retracted, the first roller part 116 and the rollers 116a and 117a of the second roller part 117 come into contact with the tip part 121 side. Since the first finger 111 and the second finger 112 are not spaced apart, a state of gripping the provided rivet 1 may be maintained. That is, the first finger 111 and the second finger 112 are elastically in close contact with each other in opposite directions without the intervention of the spacer 120 to maintain the gripping force. Therefore, in the retreating process, the finger part 110 can supply the rivet 1 to the head part 104a until just before the gripping force is released by the spacer part 120, and the finger part 110 moves in the retreating direction to the supply point. Upon reaching, the rollers 116a and 117a may come into contact with the tip portion 121, and the first roller portion 116 and the second roller portion 117 may be spaced apart by rotation.

5 is a view showing the side of the first finger 111 and the second finger 112 on which the rivet 1 is seated according to an embodiment of the present invention. ) is a diagram showing the side side.

Referring to FIG. 5A , in the finger part 110 , the rivet 1 received through the supply pipe 119 may be seated between the first finger 111 and the second finger 112 . Here, the seating is performed on the position correcting unit 113 provided between the first finger 111 and the second finger 112 , and the position correcting unit 113 may be coupled to the second finger 112 side. The position correction unit 113 may be provided with an induction unit 113a for allowing the rivet 1 to be seated in a more effectively corrected position. The induction part 113a may have a structural configuration and may be configured to promote seating through an additional configuration.

For example, the structural configuration of the induction part 113a is provided with an intaglio shape corresponding to the seating surface on which the rivet 1 is seated, and the rivet 1 provided through the supply pipe 119 is positioned while falling (F). It is to be able to be seated in an effective position and state to be supplied to the head part 104a when the correction part 113 is reached. Here, an effective position and state is such that the head of the rivet 1 faces the front side of the rivet gun 100, the shank faces the head part 104a side, and the center of the head part 104a is positioned on the extension line of the shank. That is, the surface corresponding to the seating surface of the rivet 1 as a structural configuration for the above-described preferred position correction may be engraved.

In addition, when the induction part 113a is configured to promote seating through the additional configuration, the additional configuration may be a magnetic material. The induction part 113a may guide and seat the rivet 1 falling (F) from the supply pipe 119 to a predetermined position on the position correction part 113 through magnetic force. Of course, this is a configuration possible when the rivet 1 is also a magnetic material, and can function more effectively when the finger part 110 is a non-magnetic material.

That is, the position correction unit 113 may include an induction unit 113a, and the induction unit 113a may be provided in one or more forms of the above-described structural configuration and additional configuration, preferably in a structural configuration and additional configuration. The configurations may be applied simultaneously.

Referring to FIG. 5(b), the rivet 1 provided to the supply pipe 119 may be supplied so that the head side of the rivet 1 is located in front of the supply direction. The supply pipe 119 may be disposed in a form in which the hollow portion of the supply pipe 119 is opened upward when the rivet gun 100 is disposed in the horizontal direction. Here, when the rivet gun 100 is arranged in the horizontal direction, it means that the first body part 102 is arranged in the horizontal direction, and the supply pipe 119 is spaced apart from the first body part 102 at an angle and the opening part 119a. ) may be in an upwardly open form. Here, upward means a form spaced upward from the horizontal direction including the vertical direction.

Since the head portion 104a of the rivet 1 is positioned on the front side of the supply direction in the structure of the supply pipe 119 described above, when it falls from the supply pipe 119 (F), the head part 104a is the rivet gun 100 ) may be located anteriorly. The dropped rivet 1 may be positioned in a predetermined position and shape by the position correction unit 113 as described above with reference to FIG. 5 (a). Also, the drop F from the supply pipe 119 may be made through the opening 119a formed in the supply pipe 119 . The opening 119a may be formed at the lower side of the supply pipe 119 . This is so that the rivet 1 provided to the finger part 110 can be dropped (F) by its own weight, and the portion located on the falling (F) trajectory is open. Of course, the first finger 111 also has a cutout formed as needed, like the open portion 119a, so that the fall F of the rivet 1 can be achieved.

The guide part 252 may be configured in the form of a pair of plates, and the rivets 1 may be arranged on an inclined surface. The arranged rivets 1 are moved downward by their own weight, and the alternating separation unit 255 blocks them, and the rivets 1 can be separated and discharged one by one at a predetermined time interval. The separated and discharged rivets 1 pass through the first bed 254 and the second bed 256 and are moved to the rivet transfer unit 230 along the ramp 253a of the inclined portion 253 and are riveted through hydraulic pressure. The ejection of (1) can be performed.

Specifically, the guide part 252 is provided with a guide gap 252a having a predetermined interval between the pair of plates, and the rivet 1 is inserted into the guide gap 252a with the shank of the rivet 1 inserted. ) may be moved along the inclined surface of the guide unit 252 . The alternating separation unit 255 is located on the rear side of the movement path on the guide unit 252, and the alternating separation unit 255 may block and pass the rivet 1 to be moved.

The alternating separating part 255 includes a first alternating separating part 255a and a second alternating separating part 255b. The first alternating portion may be located in front of the second alternating portion during the movement path of the rivet 1 on the guide portion 252 . In addition, the distance between the first alternating portion and the second alternating portion may be a distance equal to the diameter of the head of the rivet (1). In addition, the first alternating separating part 255a and the second alternating separating part 255b may be connected to the second bed 256 , and the second bed 256 may be connected to the reciprocating cylinder 257 . That is, as the second bed 256 is reciprocally moved in the reciprocating direction of the cylinder 130 by the reciprocation of the reciprocating cylinder 257, the first alternating separating part 255a and the second alternating separating part 255b are also reciprocating. can

In this process, in a state in which the blocking of the first alternating separating part 255a is released, the rivet 1 may move along the inclined part 253 and be blocked by the second alternating separating part 255b. Again, as the first alternating separating part (255a) intervenes on the movement path of the rivet (1), the blocking of the rivet (1) of the second alternating separating part (255b) is released and blocked by the second alternating separating part (255b). The rivet (1) is dropped (F). At the same time, the rivet (1) located on the rear side of the dropped rivet (1) may be blocked by the first alternating separation part (255a). This operation is repeated and the rivets (1) can be moved one by one by falling (F).

Here, the first bed 254 part and the second bed 256 part located on the falling (F) trajectory so that the rivet 1 can be dropped (F) to the inclined part 253 can be formed with a long hole-type through hole. There is, while reciprocating by the reciprocating cylinder 257, it is possible to allow the fall (F) of the rivet 1 only at the time when each through-hole overlaps. Accordingly, each of the through-holes may overlap at the time when the blocking from the second alternating separation unit 255b is released. Specifically, since the first bed 254 is fixed and the second bed 256 is reciprocated by the reciprocating cylinder 257, the through hole of the second bed 256 is moved to overlap the through hole of the first bed 254. will be.

8 is a flowchart illustrating a process in which the rivet 1 is transferred to the head of the rivet gun 100 by the rivet supply unit 200 according to an embodiment of the present invention.

8, the riveting method through the riveting device 10 of an embodiment of the present invention is a rivet alignment step (S10), a rivet distribution step (S20), a rivet delivery step (S30), a finger part seating step (S40) ), the head portion supply step (S50), the finger portion retreat step (S60) and may include a riveting step (S70). Each of the above-described steps may be performed according to a preset command value. The preset command value may be a time interval (delay time). For example, the preset command value is at least a rivet distribution step (S20), a rivet delivery step (S30), a finger portion seating step (S40), a head portion supply step (S50), a finger portion retraction step (S60), and a rivet It may be performed at a preset time interval in one or more steps of the setting step (S70).

Specifically, in the rivet alignment step (S10), the rivets 1 randomly received by the rivet alignment unit 220 may be aligned. The aligned rivets 1 are delivered to the delay providing unit 250 side, and the delay providing unit 250 may perform a rivet distribution step S20 of distributing the rivets 1 . The rivet 1 transferred from the delay supply unit 250 to the rivet transfer unit 230 through the rivet distribution step S20 may be discharged by hydraulic pressure and provided to the finger unit 110 . The rivet 1 provided to the finger part 110 may be seated on the position correction part 113 through the finger part seating step (S40), and the reciprocating rod 132 is drawn into the body 131 of the cylinder 130. As the finger part 110 is retracted, the rivet 1 may be supplied to the head part 104a in this process. That is, the step of supplying the head ( S50 ) and the step of retracting the fingers ( S60 ) may be sequentially performed. Thereafter, the riveting step (S70) in which riveting is performed on the riveting object by the user may be performed.

When the sequence of each step is programmed and determined, the user can determine the time interval between the sequence of each step and the next step, that is, the delay time. The time interval (delay time) can be controlled by inputting a command value through the aforementioned manipulation unit 240 .

As a specific example, it is possible to determine whether each step is performed automatically or manually by a user, and a time interval after each step is performed and a delay until the next step is performed can be set. And, since the forward or retracted state of the finger unit 110 can be detected depending on whether the sensor unit 140 detects it, the waiting time for state change from the forward or retreated state to the retreated or forward state, rivet delivery through the flexible tube The time interval at which the rivet 1 is discharged from the unit 230 can be controlled.

The setting of such a time interval may be performed interlockingly. For example, if the speed at which the finger unit 110 is advanced by the cylinder 130 is slow, a sufficient time interval (time at which the advancement of the finger unit 110 is completed) is required before the rivet delivery step S30 is performed. do. Accordingly, when a sufficient time interval is set, the time it takes for the rivet 1 to fall again (F) in the rivet distribution step (S20) may be longer. Accordingly, the time intervals can be changed and adjusted in conjunction with each other.
