Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. It will be apparent to those skilled in the art that the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, It is provided to let you know. Wherein like reference numerals refer to like elements throughout.

The lap joint welding apparatus according to the present invention includes a circulation unit 100 for circulating the supply region where the base material S is supplied and the welding region where welding is performed and the separation region where the welded base material S is separated in an endless track manner; A supply unit (200) located below the supply region and containing the base material (S); A take-out unit (300) disposed directly above the supply unit (200) to take out the different base materials (S) from the supply unit (200) by a magnetic force and sequentially seat them in the circulation unit (100) so as to overlap each other; A welding unit (400) arranged in the welding area to weld the welding part of the base material (S); And a separation unit 500 which is disposed in the separation area and separates the base materials S, which are welded by mechanical contact, from the circulation unit 100.

The region in which the circulation unit 100 circulates in an endless track manner can be largely divided into three regions: a supply region, a welding region, and a separation region. The circulating unit 100 circulates the three regions sequentially in an infinite orbit, thereby assisting in the work of welding the different parent materials S in a lap joint manner.

In the circulation unit 100, since the base material S is seated and circulates while drawing an endless track, it should not fall off from the circulation unit 100 while being circulated until the separation operation is performed. Preferably, the circulation unit 100 is provided with a magnet having magnetism and the like, and the base material S should also be made of a material such as a metal influenced by the magnetic force.

According to an embodiment of the present invention, a plurality of circulation means for circulating the respective regions with the base material S placed thereon can be provided, thereby improving the efficiency of the lap joint welding operation.

First, work must be done in which the different base material S to be welded is supplied to the circulation unit 100 in the supply region. This supply operation is performed by the organic operation of the supply unit 200 and the take-out unit 300.

The supply unit 200 exists on the outer side of the endless track and below the supply region. The base material S used for welding is stacked to serve as a plurality of base materials S from time to time.

The drawing unit 300 immediately above the feeding unit 200 sequentially draws the different parent materials S from the feeding unit 200 through an endless track through which the circulating unit 100 circulates, And supplies the base material S drawn out to the substrate 100.

At this time, the drawing operation is performed by the magnetic force. The base material S of the metal nature is taken out from the supply unit 200 by using a magnetic substance such as a magnet provided on the drawing means. By using the magnetic force as described above, the base material S having its own weight can be drawn out from the bottom to the top, and the work can be performed more efficiently than using the mechanical force. If the mechanical force is used, the equipment may be damaged due to dropping of the base material (S) during the drawing process.

According to this need, the drawing unit 300 and the feeding unit 200 must face each other with the endless track of the circulating unit 100 circulating therebetween so that the feeding and drawing operations can be performed smoothly. In addition, the circulation unit 100 must be stopped in the supply area until the supply operation is completed, while the circulation is stopped during the supply operation.

The different base materials S which are seated to overlap the circulation unit 100 by the operation of the drawing unit 300 and the supplying unit 200 move on the endless track and reach the welding area. In the welding area, the welding operation is performed at the overlapped portions of the different base materials S by the welding unit 400.

According to one embodiment of the present invention, welding is performed by spot welding, welding of welding electrodes having different electrodes sandwiching overlapped portions of different base materials S, and when current is passed through, The temperature rises sharply and the base material S melts and the overlapped portion of the base material S is welded by the pressure applied by the welding rod.

In order to perform the above-described operation, the welding electrodes having different electrodes must face each other with the endless track circulated by the circulation unit 100 facing each other. It is also clear that the circulation unit 100 must be stopped in the welding zone until the welding operation is completed, while the circulation is stopped during the welding operation.

When the welding operation is completed, the circulation unit 100 circulates again and reaches the separation area. In the separation region, an operation of separating the different base materials S, which have been welded to the circulation unit 100 by the separation unit 500, from the circulation unit 100 occurs. At the same time, a collection work for collecting the separated base material S is also performed.

Such a separation operation is performed through mechanical contact. Once the welded parent material S is separated from the circulation unit 100, recovery is automatically performed by its own weight, so that it is effective to use mechanical force. However, sufficient force must be applied to separate the base material S from the circulation unit 100. [

For this operation, the separating means and the recovering means must also face each other with the endless track in which the circulating unit 100 circulates. In addition, the circulation unit 100 should be stopped in the separation area until the separation operation is completed, while the circulation is stopped during the separation operation.

In this manner, the supply, welding, separation, and recovery operations of the base material S are sequentially performed on the circulation unit 100 circulating in the endless track manner, whereby the efficiency of the work is increased and the worker's involvement is relatively large The incidence of safety accidents is significantly lower than before.

In addition, the welded portion is formed at a constant portion, and the degree of welding is constant, so that the data calculated thereby can be also accurate.

In one embodiment of the present invention, a welding operation is performed on a specimen, and a tensile test such as a shear tension evaluation is performed on a pair of welded specimens. Precise data calculation is required to perform such an evaluation. As described above, the welding can be performed at a predetermined portion through a series of operations such as supply, welding, separation and recovery, and precise data calculation becomes possible.

The technical idea of the present invention is to provide a means for circulating a certain section in an endless track manner and circulating the same to feed, weld, separate and recover the base material S used for lap joint welding, And to provide a lap joint welding apparatus which improves the efficiency of the work while improving the precision of the lap joint.

In the lap joint welding apparatus according to the present invention, the circulation unit (100) includes a conveyor (110) circulating in an endless track manner; And a magnet for fixing the base materials S placed in the seating groove 130 by magnetic force is built in the seating groove 130, And a plurality of assembly plates 120 fixed to the conveyor 110.

The conveyor 110 draws a closed curve to form an infinite orbit. On both sides of the endless track I of the conveyor 110, a rotating roller is formed and the conveyor 110 can move in an endless track manner. A driving motor is connected to the rotating roller so that the rotating roller can be automatically driven. In addition, the rotating rollers on both sides are connected to the supporting rods, respectively, so that the conveyor 110 can be operated while being spaced apart from the ground.

A plurality of assembly plates 120 may be disposed on the conveyor 110 and may be disposed apart from each other. The lower surface of the assembly plate 120 is connected to the upper surface of the conveyor 110 and the upper surface of the assembly plate 120 is formed with a seating groove 130 in which the base materials S are seated.

In the seating groove 130, portions of different base materials S are seated in a state of overlapping each other. The seating grooves 130 of the assembly plate 120 are in the open form and different base materials S are placed thereon. E Therefore, when the assembly plate 120 circulates on the conveyor 110, when the conveyor 110 comes to the bottom of the conveyor 110, the open seating groove 130 faces downward. Therefore, at this time, a separate means is required in which the deposited base materials S do not fall off.

Therefore, it is possible to fix the base material S made of a metal by magnetic force by incorporating a magnet in the assembly plate 120. Preferably, a magnet is provided on the bottom surface of the seating groove 130 of the assembly plate 120 to contact the base material S, thereby maximizing the fixing force.

The assembly plate 120 should be positioned so that the base material S is subjected to lap joint welding. In the seating groove 130, portions where different base materials S are seated are preferably formed to have a height difference. It is necessary to perform precise welding by maintaining the horizontal position at the time of welding.

The height difference should be formed by the thickness of the base material S supplied first. In this case, the non-overlapping lower surface of the base material S supplied later is supported and the different base materials S can be kept horizontal. As a result, it is possible to precisely weld the overlapped portions of the different base materials S to each other.

In one embodiment according to the present invention, the assembly plate 120 on the conveyor 110 is circulated in an infinite orbit, but must wait until each operation is completed in the respective areas of supply, welding and separation. This can be accomplished by controlling the rotation of the rotating roller to operate the conveyor 110. [

In the lap joint welding apparatus according to the present invention, the mounting groove 130 of the assembly plate 120 is provided with a first seating groove 132 on one side where the base material S to be supplied first is placed and a base material S The second seating groove 133 on the other side where the correction plate 140 with the thickness is provided is formed so that the different base materials S are overlapped and held horizontally.

The assembly board 120 should be seated in a form in which the different base materials S are located and overlapping portions are formed. If one base material S is placed first on the flat surface and the remaining base material S is placed on the top surface thereof, if the overlapping portions are smaller than the non-overlapping portion, the later-supplied base material S is supplied first The horizontal state on the upper surface of the base material S can not be maintained.

Accordingly, a precise welding operation performed at a predetermined position of the base material S, which has been achieved through the present invention, can not be achieved.

The seating groove 130 in which the different base material S is placed is divided into the first seating groove 132 and the second seating groove 133 according to the order of the supplied base material S and the second seating groove 133 The correction plate 140 having the same thickness as that of the base material S supplied to the first placement groove 132 is provided to replace the base material S to be supplied later with the base material S supplied first and the correction plate 140 So that it can be placed on the flat surface to be formed so as to be kept horizontal.

In the lap joint welding apparatus according to the present invention, the correction plate 140 provided in the second seating groove 133 of the assembly plate 120 is adjustable in height and has the same height as the thickness of the base material S, The base material S to be supplied later may be horizontally positioned on the face formed by the base material S and the compensation plate 140 supplied first.

The correction plate 140 for forming the same height as the base material S supplied in the seating groove 130 can be designed to be adjustable in height. Preferably, a control bar connected to one side of the lower surface of the compensating plate 140 is formed, and the other side of the control bar may be vertically connected to the bottom of the second seating groove 133 of the assembling plate 120.

The height can be adjusted by the above-described method, so that even if the type of the base material S used for the lap joint welding is changed, it is possible to form the same height as the base material S to be supplied first. Therefore, it is possible to flexibly cope without any design change, and it is possible to enjoy a considerable economic effect in terms of time.

In the lap joint welding apparatus according to the present invention, the supply unit 200 has a receiving space formed therein so that the upper part thereof is opened and a plurality of base materials S are stacked, and the first and second seating grooves 132 and 133 So as to supply the different base materials S to the respective seating grooves 130. In this case,

A plurality of base materials S are stacked in the supply unit 200 to smoothly supply the base material S to the assembly plate 120. It also has a function of moving along the first and second seating grooves 132 and 133 to supply the base material S to the first seating groove 132 and the second seating groove 133 respectively.

The supply unit 200 according to an embodiment of the present invention may be configured such that the supply and reception supply container in which a plurality of base materials S are accommodated moves along the first seating groove 132 and the second seating groove 133, And a first cylinder for allowing the feed cylinder to move on the first movement axis.

A plurality of base materials (S) are stacked on the inside of the open upper part of the supply cylinder, and a plurality of base materials (S) are stacked on the upper surface of the support plate located inside the supply cylinder. A spring is provided between the bottom surface of the feed cylinder and the bottom surface of the support plate to keep the height of the base material S stacked at the top constant.

More preferably, a stopper for interrupting the withdrawal of the base material S positioned at the uppermost position may be formed in the open portion of the supply cylinder top portion. Accordingly, the best parent material S is normally interrupted by a stopper at the upper portion of the feed cylinder, and the stopper is operated only during the feeding operation to the assembly plate 120 to feed the parent materials S one by one.

A plurality of base materials S are sandwiched between the supply cylinders and friction force acts between the base materials S, so that it is difficult to draw out one base material S at a time of supplying work. In order to solve this difficulty, it is possible to smoothly draw out the base material S, which is stacked on top of the magnet at the edge of the open part of the upper part of the supply cylinder, by buoyancy formed by the magnetic force .

In the lap joint welding apparatus according to the present invention, the first and second seating grooves 132 and 133 of the assembly plate 120 are respectively formed with the outflow holes 150, The feed unit 200 is located in the endless track I of the conveyor 110 and moves together with the movement of the feed unit 200 at the upper portion of the feed cylinder. The base material S is pulled out from the holding groove 130 and the drawn base material S is seated in the seating groove 130. [

When the assembly plate 120 circulating the conveyor 110 is positioned in the supply region and the open seating groove 130 is directed downward, the assembly plate 120 temporarily stops the circulation, and when the feeding operation of the base material S is completed . In this process, the drawing unit 300 takes the role of pulling out the base material S from the feeding unit 200 positioned immediately below through the drawing hole 150 formed in the assembly plate 120. The drawing unit 300 and the feeding unit 200 move across the first mounting groove 132 and the second mounting groove 133 with the assembly plate 120 interposed therebetween. When the supply of the base material S to the first receiving groove 132 is completed, the first receiving groove 133 moves together with the second receiving groove 133 to supply the base material S to the second receiving groove 133.

In an embodiment according to the present invention, the draw-out unit 300 includes a draw-out plate that moves together with the movement of the supply unit 200, a second movement axis that forms a movement path of the draw- And a vertically movable withdrawal pin extending downward from the drawer plate.

The drawer plate is moved in conjunction with the movement of the supply unit 200. Accordingly, the base material S can be sequentially supplied to the first and second seating grooves 132 and 133. The withdrawing pin extending downward from the drawer plate is vertically movable and has a magnet at its end.

Therefore, the draw-out pin moves downward through the assembly plate 120 and passes through the draw-out hole 150 formed in the first seating groove 132. The penetrating lead pin contacts the base material S accommodated in the supply unit 200 and draws the base material S by a magnetic force. The drawing pin is moved upward while attaching the base material S to the end portion thereof so that the base material S is seated in the first seating groove 132 and fixed by the magnet built in the seating groove 130, And is removed from the drawing pin due to upward movement. Thereafter, the drawing plate and the feeding unit 200 are moved together to the second seating groove 133 side, and the above-described operation is repeated to complete the feeding operation.

In the lap joint welding apparatus according to the present invention, a welding hole 160 is formed in the seating groove 130 of the assembly plate 120 so as to vertically penetrate a portion where the different base materials S are stacked, Is composed of a monopole part 410 located in the upper part of the welding area and a pole part 420 located in the lower end of the monopole part 410 in the endless track I of the conveyor 110, Is moved downward and the other end portion 420 passes through the welding hole 160 by upward movement so that the welding is performed by contacting the upper and lower surfaces of the overlapped portions of the different parent materials S. [

When the assembly plate 120 circulating the conveyor 110 is located in the welding region after passing through the supply region and the open seating groove 130 is directed upward, the assembly plate 120 stops circulating, The welding operation is completed. The one pole portion 410 located at the upper portion of the welding region moves downward to contact the upper surface of the overlapped portion of the different parent materials S and the pole portion 420 positioned in the endless track inner portion I of the conveyor 110 is moved upward Passes through the weld hole 160 formed in the seating groove 130, and then comes into contact with the lower surface of the overlapped portion of the different parent material S.

Accordingly, the different parent materials S are welded by the heat generated by energizing the two electrodes with the overlapped portions of the different parent materials S interposed therebetween. In order to perform such an operation, the pole portion 420 should be positioned immediately under the pole portion 410. [ Preferably, the first pole portion 410 and the second pole portion 420 may be installed vertically movably, respectively, connected to the cylinder or the like.

A fixed plate 411 which is seamed simultaneously with the upper surfaces of the different base materials S placed so as to overlap in the seating groove 130 is formed in the monolithic portion 410 so that the different base materials S are fixed Welded to each other.

The fixed plate 411 is formed on the mono pole portion 410. The portion of the fixed plate 411 corresponding to the first mounting groove 132 is concurrently caulked with the upper surface of each of the different parent materials S, Is protruded by the thickness of the supplied base material (S).

If the base plate S is seamed to the fixing plate 411 by downward movement of the one pole portion 410 in a state where the assembly base plate 120 is seamed with the lower surface of the different base material S, So that it is possible to stably support the different base materials S, thereby improving the precision of welding. The portion protruding by the thickness of the base material S supplied later than the fixing plate 411 may be efficiently handled to other types of the base material S as long as the height can be adjusted as in the case of the compensation plate 140. [

In the lap joint welding apparatus according to the present invention, a separation hole 170 penetrating vertically is formed in the seating groove 130 of the assembly plate 120, and the separation unit 500 includes a collection unit 520 And a separating part 510 positioned directly above the collecting part 520 in the infinite orbit I of the conveyor 110. The collecting part 520 is made of a different parent material And the separating portion 510 is moved downward to penetrate the separating hole 170 to recover the different base materials S welded from the assembling plate 120 by mechanical contact (520) side.

When the assembly plate 120 circulating the conveyor 110 is located in the separation area after passing through the welding area and the open seating groove 130 is directed downward, the assembly plate 120 stops circulation temporarily, S is separated from the assembly plate 120 is completed. The lower part of the separating part 510 located between the conveyor 110 passes through the separating hole 170 provided in the assembling plate 120 and the mechanical force And is removed from the assembly plate 120. At this time, the removed base material S is recovered to the recovery unit 520 positioned immediately under the separation unit 510.

Preferably, the mechanical force applied to the base material S welded through the separation hole 170 should be stronger than the magnetic force of the magnet provided in the seating groove 130. Therefore, instantaneous up-and-down movement of the separation unit 510 can be efficient. The separation hole 170 may be provided in the seating groove 130 separately from the extraction hole 150 and the welding hole 160. The separation hole 170 may be replaced with the extraction hole 150 or the welding hole 160, have. This is because only the mechanical force can be transmitted through the assembly plate 120 to the different base materials S placed in the seating groove 130.

The base material S welded from the assembly plate 120 is dropped off by the separation unit 510 and is recovered to the recovery unit 520 so that the welded base material S is prevented from being damaged in the recovery process Additional means shall be provided.
