Referring to fig. 1 and 2, an embodiment of the present invention provides a welding apparatus, which includes a turntable 10, an assembling mechanism 20, and a welding mechanism 30. The turntable 10 is controllably rotatable about its own axis. The assembling mechanism 20 includes a mounting frame 21 and a bearing assembly 22 mounted on the mounting frame 21. The carrier assembly 22 is for carrying a first component A1 and a second component. The mounting bracket 21 is mounted on the turntable 10 such that the mounting bracket 21 and the bearing assembly 22 on the mounting bracket 21 rotate together with the turntable 10. Specifically, the mounting frame 21 is driven by the turntable 10 to pass through the first feeding station, the second feeding station, the welding station and the blanking station. As the mounting frame 21 rotates through the first loading station, a first component A1 (see fig. 4 or 5) is loaded onto the carrier assembly 22. As the mounting frame 21 is rotated past the second loading station, the second component is loaded onto the carrier assembly 22. As the mounting frame 21 rotates past the welding station, the first and second members are welded. The first component A1 and the second component are loaded and unloaded from the carrier assembly 22 as the mounting frame 21 rotates past the loading station. It should be noted that, the feeding and discharging of the first element A1 and the second element may be implemented by manual feeding and discharging, automatic feeding and discharging by a manipulator, or automatic feeding and discharging implemented by other transfer mechanisms, which is not limited herein.

The welding mechanism 30 is disposed in correspondence with the welding station for welding the first component A1 and the second component on the carrier assembly 22 routed through the welding station.

In the actual welding operation process, the rotary table 10 is controlled to rotate, so that the mounting frame 21 and the bearing component 22 on the mounting frame 21 are driven to sequentially pass through the first feeding station, the second feeding station, the welding station and the discharging station. When the mounting frame 21 and the bearing component 22 rotate to pass through the first feeding station, the first element A1 is fed onto the bearing component 22; when the mounting frame 21 and the bearing component 22 rotate to pass through the second feeding station, feeding the second element onto the bearing component 22; the welding mechanism 30 welds the first component A1 to the second component on the carrier assembly 22 as the mounting frame 21 and carrier assembly 22 rotate through the welding station. When the mounting frame 21 and the bearing assembly 22 rotate to the blanking station, the first element A1 and the second element (at the moment, the first element A1 and the second element are welded into a whole) on the bearing assembly 22 are blanked.

In this manner, the first component A1 and the second component on the carrier assembly 22 are welded by the welding mechanism 30 during the rotation of the carrier assembly 22 through the welding station with the turntable 10. Because the assembly mechanism 20 makes rotary motion along with the carousel 10, and first component A1 and second component location are on bearing component 22, the orbit of bearing the weight of first component A1 and second component on bearing component 22 when passing through the welding station every time is unanimous, the position of the mechanism of welding keeps unanimous mutually, consequently need not to fix a position first component A1 and second component at the welding station again before welding at every turn, the time of stopping the waiting has been saved, the production beat has been shortened greatly, and the production efficiency is improved, and then can be better satisfy the production demand.

It should be noted that the first element A1 may be one of a cell and a current collecting tray, and the second element may be the other of the cell and the current collecting tray. Specifically, in the embodiment shown in the drawings, the first element A1 is a current collecting plate, and the second element is a battery cell. Of course, in other embodiments, the first component A1 and the second component may be other components that need to be welded, and are not limited herein.

In the embodiment, the welding mechanism 30 includes a support frame 31 and a welding assembly 32 disposed on the support frame 31, and the welding assembly 32 has a flying welding head for flying welding the first member A1 and the second member which are passed through. Like this, utilize the flight soldered connection of welding mechanism 30 to rotate the first component A1 and the flight welding of second component on the carrier assembly 22 of passing through the welding station, compare with the spot welding technology among the prior art, carrier assembly 22 accomplishes the welding to first component A1 and second component promptly following the pivoted in-process of carousel 10, need not to wait for, has shortened the production beat greatly, has improved production efficiency, can satisfy the production demand more.

Further, the welding assembly 32 can be controlled to move along a preset track relative to the support frame 31, so that the welding head welds the passing first element A1 and second element during the movement of the welding head relative to the first element A1 and second element along the preset track, that is, the first element A1 and second element are welded along the preset track (i.e., the welding seam).

The movement of the welding unit 32 relative to the supporting frame 31 may be driven by a linear driving module such as a lead screw or an electric cylinder, but is not limited thereto.

The embodiment of the present invention provides an embodiment, first component A1 utilizes first carrier B1 to bear at the in-process of circulation, that is to say, first component A1 bears on first carrier B1, and first carrier B1 bearing first component A1 is loaded to bearing component 22 at first material loading station. The second element is carried by the second carrier B2 in the circulation process, that is, the second element is carried on the second carrier B2, and the second carrier B2 carrying the second element is loaded to the carrying assembly 22 at the second loading station.

Referring to fig. 4 to 5, in some embodiments, the assembling mechanism 20 further includes an absorbing assembly 23 and a jacking assembly 24 mounted on the mounting frame 21. The absorption component 23 is used for absorbing the first component A1 on the first carrier B1 on the carrying component 22. The jacking assembly 24 is used for pushing against a second element on the second carrier B2 on the bearing assembly 22 until the second element is attached to the first element A1 on the adsorption assembly 23, so as to weld the first element A1 and the second element attached to each other at a welding station.

In the embodiment, the mounting frame 21 is driven by the turntable 10 to pass through the suction station, the carrier blanking station and the jacking station. The first feeding station, the suction station, the carrier discharging station, the second feeding station, the jacking station, the welding station and the discharging station are sequentially arranged from upstream to downstream. When the mounting frame 21 rotates to pass through the suction station, the suction component 23 sucks the first element A1 on the first carrier B1 on the bearing component 22; when the mounting frame 21 rotates to pass through a carrier blanking station, blanking is carried out on a first carrier B1 on the bearing component 22, and at the moment, the first element A1 is adsorbed and fixed by the adsorption component 23; when the mounting frame 21 rotates to pass through the jacking station, the jacking assembly 24 pushes the second element on the second carrier B2 on the bearing assembly 22 until the second element is attached to the first element A1 on the adsorption assembly 23.

Thus, during actual operation, the mounting frame 21 follows the rotary table 10 to sequentially pass through the first feeding station, the suction station, the carrier discharging station, the second feeding station, the jacking station, the welding station and the discharging station. When the mounting frame 21 passes through the first loading station, loading the first carrier B1 carrying the first element A1 onto the carrier assembly 22; when the mounting frame 21 passes through the suction station, the suction component 23 sucks the first element A1 on the first carrier B1; when the mounting frame 21 passes through a carrier blanking station, blanking a first carrier B1 on the bearing component 22; when the mounting frame 21 passes through the second feeding station, feeding a second carrier B2 carrying a second element onto the carrying assembly 22; when the mounting frame 21 passes through the jacking station, the jacking assembly 24 pushes against a second element on the second carrier B2 on the bearing assembly 22 until the second element is attached to the first element A1 on the adsorption assembly 23; when the mounting frame 21 passes through the welding station, welding the first element A1 and the second element which are attached to each other by using the welding mechanism 30, removing the adsorption of the first element A1 by the adsorption component 23 after the welding is finished, and returning the jacking component 24 to the initial position to enable the first element A1 and the second element to fall back to the second carrier B2; when the mounting frame 21 passes through the blanking station, the second carrier B2 carrying the first element A1 and the second element is blanked.

In an embodiment, the suction assembly 23 and the carrying assembly 22 are sequentially arranged along the first direction X, and the suction assembly 23 is controllably movable between a first position and a second position relative to the mounting frame 21 along the first direction X. When the absorption component 23 moves to the first position, the first component A1 on the first carrier B1 on the bearing component 22 is absorbed. When the adsorption component 23 moves to the second position, the first element A1 and the first carrier B1 which are sucked are driven to separate, so that the first carrier B1 can be conveniently subjected to blanking in a subsequent step.

In the embodiment, the jacking assembly 24 is located on a side of the carrying assembly 22 facing away from the adsorption assembly 23, and the jacking assembly 24 is controllably movable between a third position and a fourth position relative to the mounting frame 21 along the first direction X. When the jacking assembly 24 moves to the third position, it is disengaged from the second member on the carrier assembly 22. When the jacking assembly 24 moves to the fourth position, the second element on the second carrier B2 on the bearing assembly 22 is pushed to move towards the first element A1 on the adsorption assembly 23 until the second element and the first element A1 are attached to each other, so that the first element A1 and the second element can be welded in the following process.

With continued reference to fig. 1, 2, 3, and 5, in one embodiment, the welding apparatus further includes a drive mechanism (not shown) having a first guide channel 411 that each extend around the axis of rotation of the turntable 10. The suction assembly 23 is provided with a first guide wheel 233 (see fig. 5), and the first guide wheel 233 is roll-fitted in the first guide passage 411.

During the rotation of the mounting frame 21 following the rotating disc 10, the first guide wheel 233 rolls along the first guide channel 411, so that under the guiding action of the first guide channel 411, the first guide wheel 233 drives the adsorption assembly 23 to move between the first position and the second position. In this way, in the process of rotating along with the turntable 10, the adsorption component 23 is driven to move between the first position and the second position along the first direction X while rotating along with the turntable 10 by the guiding effect of the first guiding channel 411 on the first guiding wheel 233.

In particular embodiments, the drive mechanism also has a second guide channel 421 extending around the axis of rotation of the turntable 10. The jacking assembly 24 is provided with a second guide wheel 243 (see fig. 5), and the second guide wheel 243 is in rolling fit in the second guide channel 421.

During the rotation of the mounting frame 21 following the rotating disc 10, the second guide wheel 243 rolls along the second guide channel 421, so that under the guiding action of the second guide channel 421, the second guide wheel 243 drives the jacking assembly 24 to move between the third position and the fourth position. In this way, the jacking assembly 24 utilizes the guiding effect of the second guiding channel 421 on the second guiding wheel 243 in the process of rotating along with the rotating disc 10, so as to drive the jacking assembly 24 to move between the third position and the fourth position along the first direction X while rotating along with the rotating disc 10.

In one embodiment, the assembly mechanism 20 further includes a buffer assembly 25, and the buffer assembly 25 includes a first mounting block 251 and a buffer elastic member 252. The first mounting block 251 is movably coupled to the mounting frame 21 in the first direction X such that the first mounting block 251 can move in the first direction X while following the rotation of the turntable 10. The first mounting block 251 is located on a side of the suction assembly 23 facing away from the jacking assembly 24. The buffering elastic member 252 abuts between the first mounting block 251 and the suction assembly 23 to provide a pre-tightening force that makes the suction assembly 23 have a moving trend toward the jacking assembly 24. Wherein the width of the first guide passage 411 in the first direction X is greater than the diameter of the first guide wheel 233 so that the first guide wheel 233 can float in the first direction X within the first guide passage 411.

Further, the drive mechanism also has a third guide channel 412 extending around the rotational axis of the turntable 10. The first mounting block 251 is provided with a third guide wheel 253 which is in rolling engagement with the third guide passage 412. The third guide wheel 253 drives the buffer assembly 25 to move in the first direction X along with the adsorption assembly 23 during the process of rolling along the third guide channel 412, so that the buffer elastic member 252 is always in a state with a certain compression amount.

Like this, when mounting bracket 21 follows carousel 10 and rotates when passing through the jacking station, first component A1 adsorbs on adsorption component 23, and first carrier B1 has been accomplished the unloading. At this time, the jacking assembly 24 starts to push the second element on the second carrier B2 on the bearing assembly 22 to move toward the first element A1 until the second element and the first element A1 on the adsorption assembly 23 are attached to each other. In the process of contacting the second element with the first element A1, since the pushing force applied to the second element by the jacking assembly 24 is transmitted to the adsorption assembly 23 through the first element A1, the adsorption assembly 23 can move towards the buffer assembly 25 against the elastic force of the buffer elastic member 252 (meanwhile, the first guide wheel 233 on the adsorption assembly 23 floats in the first guide channel 411 in the first direction X), until the elastic force provided by the buffer elastic member 252 borne by the adsorption assembly 23, the pushing force provided by the jacking assembly 24, and the self gravity reach a balance in the first direction X. That is to say, the elastic buffer member 252 buffers the impact between the jacking assembly 24 and the adsorption assembly 23, so as to prevent the jacking assembly 24 from being pushed too much to cause the impact received by the first element A1 and the second element to be too large and damaged. Alternatively, the buffering elastic member 252 may employ a spring.

Referring to fig. 1 to 3, in the embodiment, the driving mechanism includes a first guide seat 41 disposed coaxially with the turntable 10. The first guide holder 41 has a first guide passage 411 and a third guide passage 412, both extending circumferentially around the first guide holder. In this way, the first guide channel 411 and the first guide wheel 233 are used to guide the movement of the adsorption component 23 in the first direction X, so that the adsorption component 23 can accurately move between the first position and the second position in the process of rotating along with the turntable 10, thereby sucking the first element A1 on the first carrier B1. In addition, the movement of the buffering component 25 in the first direction X is guided by the rolling fit of the third guiding channel 412 and the third guiding wheel 253, so that the buffering component 25 and the adsorbing component 23 move synchronously in the first direction X when not receiving an external force (i.e., not receiving a pushing force provided by the jacking component 24), and the pushing force of the jacking component 24 can be buffered by the buffering elastic component 252 when receiving the pushing force provided by the jacking component 24.

Further, the driving mechanism further includes a second guide seat 42 disposed coaxially with the turntable 10. The first guide seat 41 has a second guide passage 421 extending circumferentially therearound. Thus, the movement of the jacking assembly 24 in the first direction X is guided by the rolling fit of the second guide channel 421 and the second guide wheel 243, so that the jacking assembly 24 can accurately move between the third position and the fourth position in the process of rotating along with the turntable 10, and the second element on the second carrier B2 on the bearing assembly 22 is pushed towards the first element A1 on the adsorption assembly 23 until the second element and the first element A1 are attached to each other.

Referring to fig. 4 and 5, in an embodiment, the supporting assembly 22 includes a supporting base 221 fixedly connected to the mounting frame 21, and the supporting base 221 has a first supporting position 223 and a second supporting position 222. The first loading station 223 is used for receiving a first carrier B1 at a first loading station, and a first component A1 is positioned on the first carrier B1. The second loading station 222 is used for receiving a second carrier B2 at a second loading station, and a second element is positioned on the second carrier B2.

The first bearing positions 223 and the second bearing positions 222 are arranged at intervals along the first direction X, the first bearing positions 223 are arranged close to the adsorption component 23, and the second bearing positions 222 are arranged close to the jacking component 24, so that the adsorption component 23 can be close to or far away from the first element A1 on the first carrier B1 in the process of moving along the first direction X, and further the first element A1 on the first carrier B1 is sucked; in addition, the jacking assembly 24 can push the second element on the second carrier B2 against the first element A1 on the adsorption assembly 23 in the process of moving along the first direction X close to the bearing assembly 22 until the two elements are attached to each other.

In one embodiment, the suction assembly 23 includes a second mounting block 231 and a suction member 232. The second mounting block 231 is movably coupled to the mounting frame 21 in the first direction X. The suction member 232 is mounted on the second mounting block 231 such that the suction member 232 can move in the first direction X along with the second mounting block 231. One side of the adsorbing member 232 facing the first bearing position 223 is provided with an adsorbing hole 2321 (see fig. 6) communicated with an external negative pressure source, so that when the adsorbing member 232 moves to contact with the first element A1 on the first carrier B1 facing the first bearing position 223 along with the second mounting block 231, the first element A1 is vacuum-adsorbed by the negative pressure formed by the adsorbing hole 2321. Further, the buffering elastic member 252 abuts between the first mounting block 251 and the second mounting block 231. The first guide wheel 233 is rotatably coupled to the second mounting block 231.

Optionally, the mounting frame 21 is provided with a first slide rail 211 extending lengthwise along the first direction X, and the second mounting block 231 is provided with a second slide block 234, wherein the second slide block 234 is slidably engaged with the first slide rail 211. In this way, the movement of the second mounting block 231 relative to the mounting frame 21 along the first direction X is guided by the movement of the second slider 234 along the first slide rail 211, so that the movement of the suction member 232 is more stable and reliable, and the first element A1 can be accurately sucked.

Optionally, a first slider 254 is disposed on the first mounting block 251, and the first slider 254 is slidably engaged with the first slide rail 211. In this way, the first slider 254 moves along the first slide rail 211 to guide the movement of the first mounting block 251 relative to the mounting frame 21 along the first direction X, so that the movement of the first mounting block 251 is more stable and reliable, and the buffering elastic member 252 can achieve a better buffering effect.

Optionally, the adsorbing member 232 is further provided with a through-hole 2322 (see fig. 6) penetrating through opposite sides thereof, and the through-hole 2322 is used for exposing the adsorbed member 232 to adsorb the first element A1, so that the flying welding head of the welding assembly 32 can weld the passed first element A1 and second element through the through-hole 2322 at the welding station.

In one embodiment, the jacking assembly 24 further includes a third mounting block 241 and a top bar 242. The third mounting block 241 is movably connected to the mounting frame 21 along the first direction X, and one end of the push rod 242 is connected to the third mounting block 241, so that the push rod 242 can move along with the third mounting block 241 along the first direction X. The other end of the push rod 242 extends toward the second bearing position 222 of the bearing assembly 22, so that when the push rod 242 moves along the first direction X toward the bearing assembly 22 along with the third mounting block 241, the push rod 242 can pass through the second carrier B2 to push the second element until the second element is pushed to be attached to the first element A1. Alternatively, the second guide wheel 243 may be rotatably mounted on the third mounting block 241.

It should be further noted that the first component A1 and the second component need to be welded for multiple times, for example, four times, and each welding is performed along a different weld, so as to ensure that the connection between the first component A1 and the second component meets the process requirements. In one embodiment, a plurality of welding stations are arranged between the jacking station and the blanking station, and the mounting frame 21 passes through the welding stations in sequence during rotation of the turntable 10. The welding mechanisms 30 are also provided in a plurality of corresponding welding stations, so that the first element A1 and the second element can be welded when the mounting frame 21 passes through each welding station.

The operation flow of the welding device of the present invention is described below with reference to the accompanying drawings:

the control rotary table 10 rotates around the axis of the control rotary table, so that the mounting frame 21 is driven to sequentially and circularly pass through the first feeding station, the suction station, the carrier discharging station, the second feeding station, the jacking station, each welding station and the discharging station.

When the mounting frame 21 passes through the first loading station, the first carrier B1 carrying the first component A1 is loaded onto the first loading station 223.

When the mounting frame 21 passes through the suction station, under the guiding action of the first guiding channel 411, the first guiding wheel 233 drives the second mounting block 231 and the suction member 232 to move downward until the suction member 232 sucks the first element A1 on the first carrier B1. Then, under the guiding action of the first guiding channel 411, the first guiding wheel 233 drives the second mounting block 231 and the absorbing member 232 to move upward, so that the first element A1 on the absorbing member 232 is separated from the first carrier B1.

When the mounting frame 21 passes through the carrier blanking station, the first carrier B1 at the first bearing station 223 is blanked.

When the mounting frame 21 passes through the second loading station, the second carrier B2 carrying the second element is loaded onto the second loading position 222.

When the mounting frame 21 passes through the jacking station, under the guiding action of the second guiding channel 421, the second guiding wheel 243 drives the third mounting block 241 and the ejector rod 242 to move upward, so that the ejector rod 242 passes through the second carrier B2 on the second bearing position 222 and pushes against the second element on the second bearing position 222 to move upward until the second element is attached to the first element A1 on the adsorption assembly 23.

The first member A1 and the second member attached to each other are welded a plurality of times by the respective welding mechanisms 30 while the mounting frame 21 passes through the respective welding stations. After the welding is completed, the adsorption member 232 releases the adsorption of the first element A1, and the third mounting block 241 and the ejector rod 242 move downward to the initial position under the guiding action of the second guiding channel 421, so that the first element A1 and the second element fall back onto the second carrier B2.

When the mounting frame 21 passes through a blanking station, blanking is performed on the second carrier B2 carrying the first element A1 and the second element, namely, one-time welding operation is completed.
