Description

Technical Field

[0001] This invention relates to the field of machining fixture technology, and in particular to a welding carrier. Background Technology

[0002] A heat sink is a device used to dissipate heat from electronic components in electrical appliances. It typically takes the form of a plate, sheet, or multiple sheets. Generally, a layer of thermally conductive silicone grease is applied to the contact surface between the electronic component and the heat sink during use. This allows the heat generated by the component to be more effectively conducted to the heat sink, and then dissipated into the surrounding air.

[0003] Heat sinks are usually assembled by heat sink assembly equipment, which typically needs to have the function of welding copper mesh onto the surface of copper sheets. However, because copper mesh is relatively thin and soft, the welding precision between the copper sheets and the copper mesh is relatively low. Summary of the Invention

[0004] Therefore, it is necessary to provide a welding carrier that can ensure high-precision welding between copper sheets and copper mesh to address the problem of low welding accuracy between copper sheets and copper mesh.

[0005] A welding carrier, comprising:

[0006] The positioning plate has a positioning surface;

[0007] A first positioning device is disposed on the positioning plate. The first positioning device has multiple positioning ends, which are configured to retract below the positioning surface or protrude above the positioning surface in response to pressure. When the multiple positioning ends protrude above the positioning surface, they form a first fixed position on the positioning surface for positioning the first welding piece.

[0008] A second positioning device is disposed on the positioning surface to form a second fixed position for positioning the second welding piece;

[0009] The first fixing position is located within the orthographic projection of the second fixing position on the positioning surface.

[0010] By setting up the welding carrier described above, initially, the positioning end protrudes from the positioning surface to form a first fixed position, and the first welding piece is fixed in the first fixed position. Then, the second welding piece is placed in the second fixed position. Since the first fixed position is located within the second fixed position, that is, the positioning end is also located within the second fixed position. At the same time, the positioning end protrudes from the positioning surface, so the second welding piece is supported on the positioning end. After the second welding piece is positioned, pressure is applied to the second welding piece, and the corresponding positioning end will also be subjected to pressure and retract towards the positioning surface until the second welding piece contacts the fixed first welding piece. At this time, the second welding piece and the first welding piece that are in contact with each other can be welded.

[0011] In this way, the first welding piece and the second welding piece are positioned sequentially by the first positioning device and the second positioning device. Moreover, the positioned second welding piece can be pressed and come into contact with the first welding piece, thereby facilitating welding with the first welding piece. This effectively improves the welding accuracy between the first welding piece and the second welding piece and ensures the reliability of the welding.

[0012] In one embodiment, the first positioning device includes a plurality of elastic positioning elements disposed on the positioning plate, and the elastic positioning elements have the positioning end. The elastic positioning elements are configured to retract or extend the positioning end in response to pressure, so that the positioning end retracts toward the positioning surface or extends away from the positioning surface.

[0013] In one embodiment, the elastic positioning member includes an elastic plunger and a plunger head. The elastic plunger is disposed on the positioning plate, and the plunger head is retractably disposed on the elastic plunger in a direction perpendicular to the positioning surface. During the retraction and extension of the plunger head, the plunger head protrudes from the positioning surface, and the plunger head has the positioning end.

[0014] In one embodiment, the first positioning device further includes a first adjusting member disposed on the positioning plate, and at least one of the elastic positioning members is connected to the first adjusting member and is reciprocating along a first direction.

[0015] In one embodiment, the positioning surface has an adjustment hole extending longitudinally along the first direction, the adjustment hole passing through opposite sides of the positioning plate, the first adjustment member being disposed on the side surface of the positioning plate opposite to the positioning surface, and the elastic positioning member being connected to the first adjustment member and passing through the adjustment hole.

[0016] In one embodiment, the first positioning device further includes a second adjusting member disposed on the positioning plate, and at least one of the elastic positioning members is connected to the second adjusting member and is reciprocating along a second direction at an angle to the first direction.

[0017] In one embodiment, the first adjusting member includes a first connecting plate, a first elastic member, and a first mounting plate. The first connecting plate is connected to the positioning plate, and the first mounting plate is reciprocally connected to the first connecting plate along the first direction. The first elastic member is connected between the first connecting plate and the first mounting plate to provide an elastic force that causes the first mounting plate to move away from or closer to the first connecting plate along the first direction. The elastic positioning member is connected to the first mounting plate.

[0018] In one embodiment, the positioning surface is further provided with at least two positioning holes, and each positioning hole is provided with a corresponding elastic positioning element.

[0019] In one embodiment, the second positioning device includes a fixing block, at least two first positioning elements and at least two second positioning elements, wherein the fixing block, at least two first positioning elements and at least two second positioning elements are all disposed on the positioning surface to enclose and form the second fixing position.

[0020] In one embodiment, the second positioning device includes a third adjusting member and a fourth adjusting member, both of which are disposed on the positioning plate;

[0021] Part of the first positioning member is connected to the third adjusting member and can reciprocate along the third direction; another part of the first positioning member is connected to the fourth adjusting member and can reciprocate along a fourth direction at an angle to the third direction.

[0022] In one embodiment, the third adjusting member includes a third connecting plate and a third elastic member. The third connecting plate is disposed on the positioning surface. A portion of the first positioning member is reciprocally connected to the third connecting plate along the third direction. The third elastic member is connected between the third connecting plate and the first positioning member and is used to provide an elastic force that causes the first positioning member to move away from the third connecting plate along the third direction.

Unless otherwise stated, singular terms may include plural forms and should not be construed as having a quantity of one. It should be understood that although the terms "first," "second," etc., may be used herein to describe various elements, these elements should not be limited by these terms. These terms are used only to distinguish one element from another. For example, a first element may be referred to as a second element without departing from the scope of the invention, and similarly, a second element may be referred to as a first element.

[0033] like Figure 1 and Figure 2 As shown, a welding carrier provided in one embodiment of the present invention includes a positioning plate 12, a first positioning device, and a second positioning device.

[0034] The positioning plate 12 has a positioning surface 122.

[0035] The first positioning device is disposed on the positioning plate 12. The first positioning device has multiple positioning ends that protrude from the positioning surface 122 to form a first fixed position for positioning the first welding piece 200 on the positioning surface 122. The multiple positioning ends are configured to retract toward the positioning surface 122 under pressure.

[0036] The second positioning device is disposed on the positioning surface 122 and is used to form a second fixed position for positioning the second welding piece 300 on the positioning surface 122, and the first fixed position is located within the second fixed position.

[0037] Please also refer to Figure 3 and Figure 4 By setting up the welding carrier described above, initially ensuring that the positioning end protrudes from the positioning surface 122 to form a first fixed position, and fixing the first welding piece 200 in the first fixed position, then placing the second welding piece 300 in the second fixed position. Since the first fixed position is located within the second fixed position, that is, the positioning end is also located within the second fixed position, and since the positioning end protrudes from the positioning surface 122, the second welding piece 300 is supported on the positioning end. Figure 3 As shown. After the second welding piece 300 is positioned, pressure is applied to the second welding piece 300, and the corresponding positioning end will also be subjected to pressure and retract towards the positioning surface 122 until the second welding piece 300 contacts the fixed first welding piece 200, as shown. Figure 4 As shown, the second welding piece 300 and the first welding piece 200 that are in contact with each other can be welded at this time.

[0038] In this way, the first welding piece 200 and the second welding piece 300 are positioned sequentially by the first positioning device and the second positioning device. Moreover, the positioned second welding piece 300 can be pressed to contact the first welding piece 200, thereby facilitating welding with the first welding piece 200. This effectively improves the welding accuracy between the first welding piece 200 and the second welding piece 300 and ensures the reliability of the welding.

[0039] It should be noted that the first welding piece 200 is a copper mesh, and the second welding piece 300 is a copper sheet. The copper mesh is a very thin copper sheet with fine holes, while the second welding piece 300 does not have fine holes.

[0040] Meanwhile, the retraction of the positioning end toward the positioning surface 122 does not precede the retraction of the positioning end to below the positioning surface. In actual use, the first welding piece 200 also has a certain thickness, and the positioning end is subjected to the pressure of the second welding piece 300. The second welding piece 300 contacts the first welding piece 200 and stops pressing down. Therefore, in actual use, it is not necessary to press the positioning end down to below the positioning surface 122.

[0041] In some embodiments, the first positioning device includes a plurality of elastic positioning elements 22 disposed on the positioning plate 12, and the elastic positioning elements 22 have positioning ends. The elastic positioning elements 22 are configured to retract or extend the positioning ends in response to pressure, so that the positioning ends retract toward the positioning surface 122 or extend away from the positioning surface 122.

[0042] As mentioned above, the positioning end does not necessarily have to retract below the positioning surface 122. Therefore, the positioning end can always protrude from the positioning surface 122 during the extension and retraction process, and the positioning end extends away from the positioning surface 122, that is, the positioning end extends upward towards the positioning surface.

[0043] Among them, the upper and lower parts of the positioning surface 122 are opposite each other, and the upper part of the positioning surface 122 is... Figure 2 Above the positioning plate 12 shown, and the positioning surface 122 serves as... Figure 2 The upper surface of the middle positioning plate 12, below the positioning surface 122 is Figure 2 The space at a height lower than the upper surface of the positioning plate 12.

[0044] Please see Figure 1 and Figure 5 Furthermore, the elastic positioning member 22 includes an elastic plunger 222 and a plunger head 224. The elastic plunger 222 is disposed on the positioning plate 12, and the plunger head 224 is retractably disposed on the elastic plunger 222 in a direction perpendicular to the positioning surface 122. During the retraction and extension, the plunger head 224 protrudes from the positioning surface 122, and the plunger head 224 has the aforementioned positioning end.

[0045] In practical applications, a spring is installed inside the elastic plunger 222. One end of the plunger head 224 is connected to the spring, and the other end protrudes from the elastic plunger 222. This allows the plunger head 224 to extend and retract in a direction perpendicular to the positioning surface 122 after the elastic plunger 222 is installed on the positioning plate 12. The positioning end is the other end of the plunger head 224 away from the spring. Of course, the plunger head 224 can also be connected to the elastic plunger 222 through other elastic structures, as long as the plunger head 224 can extend and retract in response to pressure.

[0046] In other embodiments, the plunger head 224 can be directly and retractably mounted 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.

[0047] The plunger head 224 is positioned on the elastic plunger 222, and the elastic plunger 222 is positioned on the positioning plate 12. This means that the elastic positioning element 22 can be manufactured separately and then installed on the positioning plate 12. However, if the plunger head 224 is directly positioned on the positioning plate 12, a structure similar to the elastic plunger 222 needs to be created on the positioning plate 12, which would increase the manufacturing difficulty of the positioning plate 12. Therefore, it is preferable to position the plunger head 224 on the elastic plunger 222 and then install the elastic plunger 222 on the positioning plate 12.

[0048] In some embodiments, the first positioning device further includes a first adjusting member 24, which is disposed on the positioning plate 12. At least one elastic positioning member 22 is connected to the first adjusting member 24 and is reciprocating along a first direction.

[0049] The elastic positioning member 22 is used to position the first welding piece 200. By setting the elastic positioning member 22 to move back and forth along the first direction, the size of the first fixed position can be adjusted, so as to facilitate the insertion or removal of the first welding piece 200. At the same time, the first fixed position can fix the first welding piece 200 of different sizes.

[0050] Furthermore, the first positioning device also includes a second adjusting member, which is disposed on the positioning plate 12. At least one elastic positioning member 22 is connected to the second adjusting member and can reciprocate along a second direction at an angle to the first direction.

[0051] The elastic positioning elements 22 on the first adjusting member 24 and the second adjusting member can respectively abut against the adjacent sides of the first welding piece 200. In this way, the elastic positioning elements 22 used to fix the adjacent sides of the first welding piece 200 can be adjusted, further increasing the adjustment range of the first fixed position, thereby increasing the versatility of the first positioning device.

[0052] In practical applications, the first direction and the second direction are perpendicular to each other. Specifically... Figure 1 In the middle, the first direction is left and right, and the second direction is up and down.

[0053] Please see Figure 1 and Figure 6 In some embodiments, the first adjusting member 24 includes a first connecting plate 242, a first elastic member 244, and a first mounting plate 246. The first connecting plate 242 is connected to the positioning plate 12. The first mounting plate 246 is reciprocally connected to the first connecting plate 242 in a first direction. The first elastic member 244 is connected between the first connecting plate 242 and the first mounting plate 246 to provide an elastic force that causes the first mounting plate 246 to move away from or closer to the first connecting plate 242 in the first direction. The elastic positioning member 22 is connected to the first mounting plate 246.

[0054] Furthermore, the first mounting plate 246 is reciprocally connected to the first connecting plate 242 via a guide rod in a first direction, and the first mounting plate 246 is fixedly connected to the guide rod, while the guide rod is reciprocally connected to the first connecting plate 242 in a first direction.

[0055] It should be noted that the guide rod allows one structure to reciprocate along a straight line and connect to another structure, making the connection more stable. Other embodiments of the present invention may also use the guide rod for connection, which is not limited here.

[0056] In practical applications, the first elastic element 244 is a spring, which is sleeved on the guide rod. Since the first welded piece 200 is relatively thin and soft, a spring with a small spring constant can be selected to prevent the elastic positioning element 22 from deforming the first welded piece 200 due to the pressure provided by the spring. Of course, the selection of the spring needs to ensure that the elastic positioning element 22 will not deform the first welded piece 200 and that the elastic positioning element 22 can stably fix the first welded piece 200.

[0057] In some embodiments, two elastic positioning members 22 are mounted on the first mounting plate 246, that is, the two elastic positioning members 22 can abut against the same side of the first welding piece 200 to ensure stable fixation of the first welding piece 200.

[0058] It is understood that the first welding piece 200 is elongated. In order to ensure that the first welding piece 200 is stably fixed in the first fixed position, two or more elastic positioning elements 22 can be provided on the longitudinal side of the first welding piece 200. In this embodiment, the first welding piece 200 is longitudinally arranged along the second direction, and two elastic positioning elements 22 are provided on the longitudinal side of the first welding piece 200. In actual use, more elastic positioning elements 22 can be selected according to the needs.

[0059] In some embodiments, the second adjusting member includes a second connecting plate, a second elastic member, and a second mounting plate. The second connecting plate is connected to the positioning plate 12. The second mounting plate is reciprocally connected to the second connecting plate in a second direction. The second elastic member is connected between the second connecting plate and the second mounting plate to provide an elastic force that moves the second mounting plate away from or closer to the first connecting plate in the second direction. The elastic positioning member 22 is connected to the second mounting plate.

[0060] The structure of the second adjusting member is the same as that of the first adjusting member 24, and the mode of operation is also the same. Those skilled in the art can refer to the first adjusting member 24 to install the second adjusting member accordingly, which will not be described in detail here.

[0061] Please see Figure 1In some embodiments, the positioning surface 122 is provided with an adjustment hole 124 extending longitudinally along a first direction. The adjustment hole 124 penetrates through opposite sides of the positioning plate 12. The first adjustment member 24 is disposed on the side surface of the positioning plate 12 away from the positioning surface 122. The elastic positioning member 22 is connected to the first adjustment member 24 and passes through the adjustment hole 124.

[0062] The first adjusting member 24 is installed on the surface of the positioning plate 12 opposite to the positioning surface 122. The installation of the first adjusting member 24 will not affect the fixation of the second welding piece 300. It can also be understood that the size of the adjusting hole 124 can be determined according to the size of the elastic positioning member 22 and the travel of the elastic positioning member 22.

[0063] Furthermore, the positioning surface 122 is also provided with an adjustment groove 126, and the elastic positioning member 22 connected to the second adjustment member passes through the adjustment groove 126.

[0064] In some embodiments, the positioning surface 122 is further provided with at least two positioning holes, and an elastic positioning member 22 is provided in each positioning hole. Further, the at least two are divided into two groups, and the two groups of positioning holes are opened on adjacent sides of the first welding piece 200, that is, the elastic positioning member 22 provided in the positioning hole will abut against the adjacent sides of the first welding piece 200.

[0065] In practical applications, one set of positioning holes is set opposite to the adjustment hole 124 in the first direction, and another set of positioning holes is set opposite to the adjustment groove 126 in the second direction. That is, the elastic positioning member 22 in the positioning hole can abut against the adjacent two sides of the first welding piece 200, while the elastic positioning member 22 on the first adjustment member 24 and the second adjustment member abut against the other two sides of the first welding piece 200, thereby fixing the first welding piece 200.

[0066] Similarly, it is understandable that two or more positioning holes can be opened on the longitudinal side of the first welding piece 200 to ensure more stable positioning of the first welding piece 200.

[0067] Please see Figure 1 and Figure 2 In some embodiments, the second positioning device includes a fixing block 31, at least two first positioning elements 32 and at least two second positioning elements 34. The fixing block 31, at least two first positioning elements 32 and at least two second positioning elements 34 are all disposed on the positioning surface 122 for enclosing and forming a second fixed position.

[0068] In some embodiments, the second positioning device includes a third adjusting member 36, which is disposed on the positioning plate 12. A portion of the first positioning member 32 is connected to the third adjusting member 36 and is reciprocating along a third direction. Thus, the second fixed position can be adjusted by the reciprocating movement of the first positioning member 32 along a third direction, facilitating the insertion or removal of the second welding piece 300, and also allowing the second fixed position to fix second welding pieces 300 of different sizes.

[0069] It can also be determined that the size of the second welding piece 300 is larger than the size of the first welding piece 200. Therefore, even though the sizes of the second fixing position and the first fixing position can be adjusted, after the first welding piece 200 and the second welding piece 300 are actually fixed, the first fixing position is still located within the orthographic projection of the second fixing position on the positioning surface 122.

[0070] It should be explained that the first adjusting member 24 is set on the side of the positioning plate 12 away from the positioning surface 122 so as not to affect the fixing of the second welding piece 300. Since the size of the second welding piece 300 is larger than the size of the first welding piece 200, the size of the second fixing position for fixing the second welding piece 300 is larger than the size of the first fixing position for fixing the first welding piece 200. Therefore, the third adjusting member 36 can be directly set on the positioning surface 122.

[0071] Furthermore, the third adjusting member 36 includes a third connecting plate 362 and a third elastic member 364. The third connecting plate 362 is disposed on the positioning surface 122. The first positioning member 32 is reciprocally connected to the third connecting plate 362 in a third direction. The third elastic member 364 is connected between the third connecting plate 362 and the first positioning member 32 and is used to provide an elastic force that causes the first positioning member 32 to move away from the third connecting plate 362 in a third direction.

[0072] Combining the above embodiments and Figure 6 It should be explained that the first adjusting member 24 is disposed on the side surface of the positioning plate 12 opposite to the positioning surface 122, and the first adjusting member 24 will not affect the fixation of the second welding piece 300. To enable the first elastic member 244 to drive the first mounting plate 246 to move in the same direction, the first connecting plate 242 can be disposed on the inner side, i.e. Figure 6 On the left side of the first mounting plate 246, the first elastic element 244 pulls the first mounting plate 246 closer to the first connecting plate 242 to fix the first welding piece 200; alternatively, the first connecting plate 242 can be positioned on the outside, i.e., as shown in the image. Figure 6 As shown, at this time, the first elastic member 244 pushes the first mounting plate 246 away from the first connecting plate 242, which can also achieve the fixation of the first welding piece 200.

[0073] As for the third adjusting member 36, the third connecting plate 362 is located on the inner side, that is, the third connecting plate 362 is located in the first fixed position or the second fixed position, which will affect the installation of the first welding piece 200 and / or the second welding piece 300. Therefore, the third connecting plate 362 needs to be located on the outer side, and the third elastic member 364 drives the first positioning member 32 away from the third connecting plate 362 to fix the second welding piece 300.

[0074] In practical applications, the third elastic element 364 is a spring. Using a spring makes it easier to adjust the elastic force. That is, you can choose a spring with a suitable stiffness coefficient to avoid the second welding piece 300 being deformed due to excessive elastic force or the fixation being unstable due to insufficient elastic force.

[0075] In some embodiments, the second positioning device further includes a fourth adjusting member 38, which is disposed on the positioning plate 12, and another part of the first positioning member 32 is connected to the fourth adjusting member 38 and can reciprocate along a fourth direction at an angle to the third direction.

[0076] The first positioning member 32 on the third adjusting member 36 and the first positioning member 32 on the fourth adjusting member 38 can respectively abut against the adjacent two sides of the second welding piece 300.

[0077] It is understandable that the third adjusting member 36 and the fourth adjusting member 38 have the same function as the first adjusting member 24 and the second adjusting member, which can make the first positioning member 32 on both sides of the second welding piece 300 adjustable, further increasing the adjustment range of the second fixed position, thereby increasing the versatility of the second positioning device.

[0078] Furthermore, the structure of the fourth adjusting member 38 is the same as that of the third adjusting member 36, and will not be described in detail here.

[0079] In practical applications, the third direction is perpendicular to the fourth direction. Specifically, the third direction is the same as the first direction, which is... Figure 1 The left and right directions are the same as the second and fourth directions. Figure 1 The up and down directions in the middle.

[0080] In some embodiments, the first positioning member 32 is a positioning block or clamping plate, and the second positioning member 34 is a positioning pin. In practical applications, the third adjusting member 36 is provided with a clamping plate, and a plurality of positioning pins are provided on the opposite side of the third adjusting member 36 so as to abut against the clamping plate on the opposite sides of the second welding piece 300 along the third direction, while the fourth adjusting member 38 is provided with a positioning block.

[0081] Furthermore, the fixing block 31 is disposed on the positioning surface 122 and is disposed opposite to the fourth adjusting member 38 in the fourth direction. The positioning block on the fourth adjusting block and the fixing block 31 fixed on the positioning surface 122 respectively abut against the opposite sides of the second welding piece 300 along the fourth direction.

[0082] In other embodiments, the third direction is the first direction, the fourth direction is the second direction, and the second adjusting member and the fourth adjusting member 38 are of the same structure, that is, the second adjusting member is the fourth adjusting member 38. The fourth adjusting member 38 is disposed in the adjusting groove 126, and at least one elastic positioning member 22 and another part of the first positioning member 32 are connected to the fourth adjusting member 38.

[0083] Furthermore, the fourth adjusting member 38 includes a fourth connecting plate 382 and a fourth elastic member 384. The fourth connecting plate 382 is disposed within the adjusting groove 126. The first positioning member 32 on the fourth adjusting member 38 is reciprocally connected to the fourth connecting plate 382 along the second direction. The fourth elastic member 384 is connected between the first positioning member 32 and the fourth connecting plate 382, ​​and is used to push the first positioning member 32 away from the fourth connecting plate 382. The elastic positioning member 22 is disposed on the first positioning member 32.

[0084] In practical applications, the first positioning member 32 connected to the fourth elastic member 384 is a positioning block. The positioning block includes a positioning part 322 and a protrusion 324. The positioning part 322 is reciprocally connected to the fourth connecting plate 382 along the second direction. The protrusion 324 is connected to the side of the positioning part 322 away from the fourth connecting plate 382. The elastic positioning member 22 is disposed on the protrusion 324.

[0085] It should be noted that, in order to ensure that the first welding piece 200 is located below the second welding piece 300 during positioning, the height of the protrusion 324 is lower than the height of the positioning part 322. At the same time, the top of the positioning part 322 is chamfered to enclose the side forming the second fixing position, so as to guide the insertion of the second welding piece 300 and facilitate the insertion of the second welding piece 300 into the second fixing position.

[0086] In some embodiments, the welding carrier further includes a first driving member, which is tractively connected to the first mounting plate 246 and drives the first mounting plate 246 to move closer to or away from the first connecting plate 242 against the elastic force of the first elastic member 244. Thus, the first driving member drives the elastic positioning member 22 to move and open the first fixed position, facilitating the insertion or removal of the first welding piece 200.

[0087] Furthermore, the welding carrier also includes a second drive member, a third drive member, and a fourth drive member. The second drive member is drivenly connected to the second mounting plate, the third drive member is drivenly connected to the first positioning member 32 disposed on the third adjusting member 36, and the fourth drive member is drivenly connected to the first positioning member 32 disposed on the fourth adjusting member 38.

[0088] It is understandable that the second, third, and fourth driving components have the same function as the first driving component: to open the first or second fixed position, thereby facilitating the insertion or removal of the first welding piece 200 or the second welding piece 300. This will not be elaborated upon here.

[0089] Furthermore, when the second elastic element is the fourth elastic element 384, the second driving element and the fourth driving element are the same driving element.

[0090] Of course, in other embodiments, when the second elastic member is the fourth elastic member 384, the first driving member can be driven to the first connecting plate 242 to drive the first adjusting member 24 to reciprocate along the first direction, the corresponding fourth driving member is driven to the fourth connecting plate 382 to drive the fourth adjusting member 38 to reciprocate along the second direction, and the third driving member is driven to the third connecting plate 362 to drive the third adjusting member 36 to reciprocate along the first direction.

[0091] Understandably, at this time, the springs in the first adjusting member 24, the third adjusting member 36, and the fourth adjusting member 38 are used to buffer the movement of the driving member toward the first welding piece or the second welding piece.

[0092] Taking the first adjusting member 24 as an example, after the first welding piece 200 is placed in the first fixed 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 the compressed state.

[0093] To facilitate understanding of the technical solution of the present invention, the working method of the welding carrier in the above embodiments is described below:

[0094] Initially, the first and fourth driving components push the first mounting plate 246 and the first positioning component 32 on the fourth adjusting component 38 to open the first fixed position. At the same time, the copper mesh is transported to the first fixed position by a robot or other handling mechanism. Then, the first and fourth driving components reset. As the driving components return to their original positions, the first mounting plate 246 and the corresponding first positioning component 32 will also move towards the copper mesh under the action of the first elastic component 244 and the fourth elastic component, so that the elastic positioning component 22 abuts against and fixes the copper mesh.

[0095] After the copper mesh is fixed, the first positioning member 32 is pushed by the third driving member to open the second fixed position. At the same time, the copper sheet is transported to the second fixed position by a robot or other handling mechanism, and guided by the positioning part 322 of the first positioning member 32 to be supported on the positioning end of the elastic positioning member 22. Then the third driving member slowly returns to its original position. Similarly, the first positioning member 32 on the third adjusting member 36 will be pushed by the spring to move toward the copper sheet and finally abut against and fix the copper sheet.

[0096] After the copper sheet is fixed, pressure is applied to the side of the copper sheet away from the copper mesh using a pressure device, causing the copper sheet to move toward the copper mesh and come into contact with it. Next, the copper mesh and the copper sheet that are in contact are welded. After the welding is completed, the pressure device is slowly removed. The copper sheet will slowly rise under the push of the elastic positioning member 22, and the copper mesh welded to the copper sheet will also rise accordingly. Finally, the copper sheet can be removed.

[0097] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0098] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
