The second positioning device is disposed on the positioning surface 122, and is used to form a second fixing position for positioning the second welding sheet 300 on the positioning surface 122, and the first fixing position is located in the second fixing position.

Referring to fig. 3 and 4, by providing the welding carrier, it is initially ensured that the positioning end protrudes from the positioning surface 122 to form a first fixing position, and the first welding piece 200 is fixed at the first fixing position, and then the second welding piece 300 is placed at the second fixing position, and since the first fixing position is located in the second fixing position, that is, the positioning end is also located in the second fixing position, and the positioning end protrudes from the positioning surface 122, the second welding piece 300 is supported on the positioning end, as shown in fig. 3. After the second welding piece 300 is positioned, pressure is applied to the second welding piece 300, and the corresponding positioning end is also pressed to retract to the positioning surface 122 until the second welding piece 300 is in contact with the fixed first welding piece 200, as shown in fig. 4, and at this time, the welding process can be performed on the second welding piece 300 and the first welding piece 200 which are in contact with each other.

So, first welding piece 200 loops through first positioner and second positioner with second welding piece 300 and fixes a position, and second welding piece 300 after the location can the pressurized contact with first welding piece 200 moreover to conveniently weld with first welding piece 200, improved welded precision between first welding piece 200 and the second welding piece 300 effectively, ensured the welded reliability.

Note that the first bonding pad 200 is a copper mesh, the second bonding pad 300 is a copper sheet, the copper mesh is a thin copper sheet with fine holes, and the second bonding pad 300 has no fine holes.

Meanwhile, the positioning end retracts towards the positioning surface 122 and does not retract below the positioning surface before the positioning end, and during actual use, the first welding sheet 200 also has a certain thickness, the positioning end is pressed by the second welding sheet 300, and the second welding sheet 300 is contacted with the first welding sheet 200 and stops pressing down, so that the positioning end does not need to be pressed down below the retracted positioning surface 122 during actual use.

In some embodiments, the first positioning device comprises a plurality of elastic positioning members 22, the plurality of elastic positioning members 22 are disposed on the positioning plate 12, and the elastic positioning members 22 have positioning ends, and the elastic positioning members 22 are configured to retract into or extend out of the positioning ends in response to a pressure force so that the positioning ends retract toward the positioning surface 122 or extend away from the positioning surface 122.

As mentioned above, the positioning end does not have to be retracted below the positioning surface 122, so the positioning end may always protrude from the positioning surface 122 during the telescoping process, and the positioning end extends away from the positioning surface 122, i.e. the positioning end extends upward of the positioning surface.

The upper side and the lower side of the positioning surface 122 are opposite, the upper side of the positioning surface 122 is the upper side of the positioning plate 12 shown in fig. 2, the positioning surface 122 is the upper side surface of the positioning plate 12 in fig. 2, and the lower side of the positioning surface 122 is the space lower than the upper side surface of the positioning plate 12 in fig. 2.

In practical applications, a spring is disposed inside the elastic plunger 222, and one end of the plunger head 224 is connected to the spring, and the other end protrudes out of the elastic plunger 222, so that after the elastic plunger 222 is installed on the positioning plate 12, the plunger head 224 can extend and retract along a direction perpendicular to the positioning surface 122, and the positioning end is the other end of the plunger head 224 away from the spring. Of course, the plunger head 224 may be connected to the elastic plunger 222 by other elastic structures as long as the plunger head 224 can be extended and retracted and can be extended and retracted in response to pressure.

In other embodiments, the plunger head 224 may be directly disposed on the positioning plate 12 in a direction perpendicular to the positioning surface 122, and the plunger head 224 protrudes from the positioning surface 122 during the extension and retraction process.

The plunger head 224 is disposed on the elastic plunger 222, and the elastic plunger 222 is disposed on the positioning plate 12, that is, the elastic positioning member 22 can be separately manufactured, and then the elastic positioning member 22 is mounted on the positioning plate 12. If the plunger head 224 is directly disposed on the positioning plate 12, a structure similar to the elastic plunger 222 needs to be disposed on the positioning plate 12, which increases the difficulty of manufacturing the positioning plate 12, so it is preferable to dispose the plunger head 224 on the elastic plunger 222 and dispose the elastic plunger 222 on the positioning plate 12.

In some embodiments, the first positioning device further includes a first adjusting member 24, the first adjusting member 24 is disposed on the positioning plate 12, and the at least one elastic positioning member 22 is connected to the first adjusting member 24 and is reciprocally movable along the first direction.

It should be noted that, the guide rod can make one structure connect to another structure in a reciprocating manner along a certain linear direction, and make the connection more stable, the present invention can also adopt the connection by way of the guide rod in other embodiments, and is not limited herein.

In practical applications, the first elastic member 244 is a spring, and the spring is sleeved on the guide rod, and since the first welding piece 200 is relatively thin and soft, the spring with a smaller stiffness coefficient can be selected to avoid the pressure provided by the spring to make the elastic positioning member 22 press and deform the first welding piece 200. Of course, the selection of the spring is required to ensure that the elastic positioning member 22 does not press the first welding piece 200 to deform and the elastic positioning member 22 can stably fix the first welding piece 200.

In some embodiments, the first mounting plate 246 is mounted on two elastic positioning members 22, that is, the two elastic positioning members 22 can abut against the same side of the first welding piece 200, so as to ensure stable fixing of the first welding piece 200.

So, accessible first locating piece 32 is along the reciprocating motion of third direction, realizes conveniently putting into or taking off second welding piece 300 to the regulation of the fixed position of second, also makes the second fixed position can fix the second welding piece 300 of equidimension not simultaneously.

Meanwhile, it can be determined that the size of the second welding sheet 300 is larger than that of the first welding sheet 200, and therefore, even though the sizes of the second fixing position and the first fixing position are both adjustable, after the first welding sheet 200 and the second welding sheet 300 are actually fixed, the first fixing position is still located in the orthographic projection of the second fixing position on the positioning surface 122.

It should be explained that the first adjusting member 24 is disposed on a side surface of the positioning plate 12 away from the positioning surface 122, which does not affect the fixing of the second welding sheet 300, and since the size of the second welding sheet 300 is larger than that of the first welding sheet 200, the size of the second fixing position for fixing the second welding sheet 300 is larger than that of the first fixing position for fixing the first welding sheet 200, and therefore the third adjusting member 36 can be directly disposed on the positioning surface 122.

In practical application, the third elastic member 364 is a spring, and the spring can be used for adjusting the elastic force more conveniently, that is, the spring with a proper stiffness coefficient is selected, so that the second welding sheet 300 is prevented from being deformed due to too large elastic force or being unstably fixed due to too small elastic force.

Of course, in other embodiments, when the second elastic member is the fourth elastic member 384, the first driving member may be in driving connection with the first connecting plate 242 for driving the first adjusting member 24 to reciprocate along the first direction, and correspondingly the fourth driving member is in driving connection with the fourth connecting plate 382 for driving the fourth adjusting member 38 to reciprocate along the second direction, and the third driving member is in driving connection with the third connecting plate 362 for driving the third adjusting member 36 to reciprocate along the first direction.

It will be appreciated that the springs in the first, third and

fourth adjustment members

24, 36, 38 are now used to provide a damping action during the driving of the driving member towards the first or second weld tab.

Taking the first adjusting member 24 as an example, after the first welding piece 200 is placed in the first fixing position, the first driving member 24 pushes the first adjusting member 24 to move toward the first welding piece 200 until the elastic positioning member 22 on the first adjusting member 24 abuts against one side of the first welding piece 200, and the first elastic member 244 enters a compressed state.

In order to facilitate understanding of the technical solution of the present invention, the working method of the welding carrier in the above embodiment is described here:

the first positioning element 32 on the first mounting plate 246 and the fourth adjusting element 38 is pushed by the first driving element and the fourth driving element initially, the first fixing position is opened, meanwhile, the copper wire is conveyed to the first fixing position by a manipulator or other carrying mechanism, then the first driving element and the fourth driving element are reset, the first mounting plate 246 and the corresponding first positioning element 32 can also move towards the copper wire under the action of the first elastic element 244 and the fourth elastic element when the driving elements are restored, and finally, the elastic positioning element 22 is abutted to the fixed copper wire.

After the copper mesh is fixed, the third driving part pushes the first positioning part 32, the second fixing position is opened, meanwhile, the copper sheet is conveyed to the second fixing position through the mechanical arm or other conveying mechanisms and guided by the positioning part 322 of the first positioning part 32 to be supported on the positioning end of the elastic positioning part 22, then the third driving part is slowly recovered, and similarly, the first positioning part 32 on the third adjusting part 36 is pushed by the spring to move towards the copper sheet and finally abut against the fixed copper sheet.

After the copper sheet is fixed, a pressing device is used for pressing the side, away from the copper mesh, of the copper sheet, so that the copper sheet moves towards the copper mesh and is in contact with the copper mesh, then the copper mesh and the copper sheet which are in contact are welded, after the welding is completed, the pressing device is slowly removed, the copper sheet can slowly rise under the pushing of the elastic positioning piece 22, the copper mesh welded with the copper sheet can also rise along with the copper sheet, and finally the copper sheet is taken down.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
