Description

Technical Field

[0001] This invention relates to the field of battery manufacturing technology, specifically to welding equipment. Background Technology

[0002] Hydrogen fuel cells utilize electrode meshes and plates, which typically form an "electrode mesh-plate-electrode mesh" structure. Adjacent electrode meshes and plates are connected by welding. In existing technologies, for structures requiring welding on both sides, welding equipment usually includes sequentially arranged front welding stations, flipping stations, and reverse welding stations. This results in large footprints and low welding efficiency for the welding equipment. Summary of the Invention

[0003] In view of this, the present invention provides a welding device to solve the problems of large footprint and low welding efficiency of existing welding devices.

[0004] This invention provides a welding device, comprising: a plurality of welding stations; a plurality of pressing mechanisms, each corresponding to one of the welding stations, the pressing mechanisms being adapted to be close to or away from the welding stations; a conveying mechanism adapted to convey workpieces to be welded to the plurality of welding stations and adapted to flip over single-sided welded workpieces that have been welded on one side at the welding stations; a temporary storage mechanism disposed on the pressing mechanisms, the temporary storage mechanism being adapted to receive the flipped single-sided welded workpieces and, driven by the pressing mechanisms, place the single-sided welded workpieces at the welding stations; and a welding mechanism movably disposed corresponding to the plurality of welding stations.

[0005] Beneficial effects: By setting up multiple welding stations, a conveyor mechanism can be used to feed materials to multiple stations in sequence, and a welding mechanism can be used to weld the parts to be welded at multiple welding stations in sequence. The conveyor mechanism can also flip single-sided welding parts and place the flipped single-sided welding parts at a temporary storage mechanism. Furthermore, while welding is being performed at one welding station, materials can be fed or flipped at another welding station at the same time. Therefore, welding efficiency can be improved, equipment utilization can be increased, and there is no need to set up a separate flipping station, saving space.

[0006] In one optional embodiment, the conveying mechanism includes a conveying drive structure, an installation structure, an electrode plate picking assembly, and an electrode mesh picking assembly. The conveying drive structure is connected to the installation structure in a transmission manner, and both the electrode plate picking assembly and the electrode mesh picking assembly are disposed on the installation structure. The conveying mechanism has an electrode plate picking state and an electrode mesh picking state. In the electrode plate picking state, the conveying mechanism picks up the electrode plate through the electrode plate picking assembly, and in the electrode mesh picking state, the conveying mechanism picks up the electrode mesh through the electrode mesh picking assembly.

[0007] Beneficial effects: When electrode plates need to be fed, the electrode plate picking assembly picks up the electrode plates, and the conveyor drive structure drives the installation structure, along with the electrode plates, to move synchronously to the welding station for feeding. When electrode mesh needs to be fed, the electrode mesh picking assembly picks up the electrode mesh, and the conveyor drive structure drives the installation structure, along with the electrode mesh, to move synchronously to the welding station for feeding. Therefore, the conveyor mechanism can feed both electrode plates and electrode mesh.

[0008] In one optional embodiment, the electrode plate picking assembly includes a first driving structure and an electrode plate suction structure. The first driving structure is disposed on the mounting structure and is adapted to drive the electrode plate suction structure to move. In the electrode plate picking state, the electrode plate suction structure protrudes from the side of the mounting structure facing the electrode plate.

[0009] Beneficial effects: When picking up material from the electrode plate, the first driving structure drives the electrode plate picking structure to move toward the electrode plate and protrude from the mounting structure, which facilitates the picking up of the electrode plate.

[0010] In one optional embodiment, the first driving structure includes a vertical driving part and a radial driving part, the radial driving part is disposed on the mounting structure, the vertical driving part is connected to the driving end of the radial driving part, and the driving end of the vertical driving part is connected to the electrode plate absorption structure.

[0011] Beneficial effects: The radial drive unit drives the vertical drive unit, together with the electrode plate suction structure, to move radially along the mounting structure, thereby adjusting the radial position of the electrode plate suction structure to match the size of the electrode plate to be suctioned; the vertical drive unit drives the electrode plate suction structure to move vertically, realizing the suction of the electrode plate and avoiding the electrode mesh material handling process.

[0012] In one optional embodiment, the electrode mesh material handling assembly includes a second driving structure, a electrode mesh picking structure, and an electrode mesh pressing structure. The second driving structure is disposed on the mounting structure and is adapted to drive the electrode mesh picking structure to move radially along the mounting structure. The picking end of the electrode mesh picking structure and the pressing end of the electrode mesh pressing structure are adapted to be disposed on opposite sides of the electrode mesh.

[0013] Beneficial effects: The electrode mesh is lifted along the radial direction by the electrode mesh lifting structure, and then the electrode mesh is pressed by the electrode mesh pressing structure, thereby achieving the clamping and fixing of the electrode mesh and ensuring the stability of electrode mesh material picking.

[0014] In one optional embodiment, the scooping mesh structure includes a connecting block, an extension plate, a vertical plate, and a hook end. The driving end of the second driving structure is connected to the connecting block. The first end of the extension plate is connected to the side of the connecting block away from the second driving structure. The upper end of the vertical plate is connected to the second end of the extension plate. The lower end of the vertical plate extends downward out of the mounting structure. The hook end is disposed at the lower end of the vertical plate and extends in a direction close to the mounting structure, forming the scooping end.

[0015] In one optional embodiment, the pressure plate structure includes a pressure block and a pressure block driving part, the pressure block driving part is disposed on the pressure plate structure, the pressure block driving part is adapted to drive the pressure block to move vertically, the pressure block passes through the extension plate and corresponds to the hook end.

[0016] Beneficial effects: By placing the pressure block drive unit on the electrode mesh structure and allowing the pressure block to penetrate through the extension plate, it is easier for the pressure block and the hook end to correspond and cooperate, thereby improving the stability of the electrode mesh material handling process.

[0017] In one optional embodiment, the conveying mechanism further includes a position detection unit electrically connected to the conveying drive structure, the position detection unit being adapted to detect the relative position of the electrode mesh structure and the electrode mesh.

[0018] Beneficial effect: When the position detection unit detects that the position of the pole-collecting mesh structure corresponds to the position of the pole mesh, it sends a signal to the conveying drive structure, causing the conveying drive structure to stop driving, thus ensuring the accuracy of the relative position of the pole-collecting mesh structure and the pole mesh.

[0019] In one optional embodiment, a plurality of electrode plate feeding assemblies are arranged at circumferential intervals along the mounting structure; and / or, a plurality of electrode mesh feeding assemblies are arranged at circumferential intervals along the mounting structure.

[0020] Beneficial effects: While further ensuring the stability of material feeding to the electrode plates and / or electrode mesh, it eliminates vertical unevenness during material feeding, keeping the electrode plates and / or electrode mesh horizontal.

[0021] In one optional embodiment, the temporary storage mechanism includes a third driving structure, a connecting structure, and a temporary storage adsorption structure. The third driving structure is disposed on the pressing mechanism. The connecting structure connects the driving end of the third driving structure and the temporary storage adsorption structure. The third driving structure is adapted to drive the connecting structure to rotate and drive the temporary storage adsorption structure to rotate. The temporary storage adsorption structure has an adsorption position and a clearance position. In the adsorption position, the temporary storage adsorption structure is not higher than the pressing surface of the pressing mechanism. In the clearance position, the temporary storage adsorption structure is located above the pressing mechanism.

[0022] Beneficial effects: When it is necessary to temporarily store a single-sided welded part, the connecting structure is driven to rotate by the third drive structure, so that the connecting structure moves the temporary storage adsorption structure to below the pressing surface of the pressing mechanism. This facilitates the temporary storage of the single-sided welded part below the pressing mechanism and makes it easier to place the single-sided welded part back on the welding station. When it is necessary to use the pressing mechanism to press the part to be welded, the connecting structure is driven to rotate by the third drive structure, so that the connecting structure moves the temporary storage adsorption structure to above the pressing mechanism. This avoids the temporary storage adsorption structure affecting the pressing mechanism and the welding mechanism.

[0023] In one optional embodiment, the connecting structure includes a lever and a connecting rod. One end of the lever is hinged to the driving end of the third driving structure, and the other end of the lever is connected to the temporary adsorption structure via the connecting rod. The lever and the fixing part of the third driving structure have a hinge point located between the two ends of the lever.

[0024] Beneficial effect: When one end of the lever is driven to rotate by the third drive structure, the lever rotates around the hinge point, thereby causing the other end of the lever to drive the connecting rod to rotate synchronously with the temporary adsorption structure.

[0025] In one alternative embodiment, a plurality of temporary storage mechanisms are provided at circumferential intervals along the pressing mechanism.

[0026] Beneficial effect: By setting several temporary storage mechanisms, the stability of adsorption on single-sided welded parts can be guaranteed.

[0027] In one optional embodiment, the pressing mechanism includes a pressing drive structure and a pressure plate, the pressing drive structure being throttle-connected to the pressure plate, and the temporary storage mechanism being disposed on the pressure plate.

[0028] In one optional embodiment, the welding equipment further includes an electrode plate loading station, an electrode mesh loading station, and a finished product unloading station, and the conveying mechanism is movably configured to correspond to several of the welding stations, the electrode plate loading station, the electrode mesh loading station, and the finished product unloading station.

[0029] In one optional embodiment, a plurality of the welding stations, the electrode mesh loading station, the electrode plate loading station, and the finished product unloading station are arranged sequentially around the outer periphery of the conveying mechanism.

[0030] Beneficial effects: By setting up several welding stations, electrode mesh loading stations, electrode plate loading stations, and finished product unloading stations around the outer periphery of the conveying mechanism, it is easier for the conveying mechanism to load electrode plates and electrode meshes and unload finished products, optimize the movement path of the conveying mechanism, facilitate the flow of the conveying mechanism between various stations, and further improve processing efficiency.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] The following is combined Figures 1 to 7 The following describes embodiments of the present invention.

[0043] According to an embodiment of the present invention, a welding device is provided for welding a "grid-plate-grid" structure, including a welding station 1, a pressing mechanism 2, a conveying mechanism 3, a temporary storage mechanism 4, and a welding mechanism 5. Several welding stations 1 and several pressing mechanisms 2 are provided, each corresponding to one welding station 1. The pressing mechanisms 2 are adapted to be close to or away from the welding stations 1. The welding mechanisms 5 are movably arranged corresponding to the several welding stations 1. The conveying mechanism 3 is adapted to convey the workpieces to be welded to the several welding stations 1 and to flip over single-sided welded workpieces that have been welded on one side at the welding station 1. The temporary storage mechanism 4 is disposed on the pressing mechanism 2 and is adapted to receive the flipped single-sided welded workpieces and, driven by the pressing mechanism 2, place the single-sided welded workpieces at the welding station 1.

[0044] By setting up several welding stations 1, the conveying mechanism 3 can be used to feed materials to several stations in sequence, and the welding mechanism 5 can be used to weld the parts to be welded on several welding stations 1 in sequence. The conveying mechanism 3 can also flip the single-sided welding parts and set the flipped single-sided welding parts in the temporary storage mechanism 4. Furthermore, when welding is performed on one welding station 1, the other welding station 1 can be fed or flipped at the same time. Therefore, welding efficiency can be improved, equipment utilization can be increased, and there is no need to set up a separate flipping station, saving space.

[0045] It is worth noting that a single-sided welded part refers to a workpiece that has already completed the welding of an electrode mesh on one side of the electrode plate, but still needs to have an electrode mesh welded on the other side of the electrode plate.

[0046] It should be noted that the welding mechanism 5 is rotatable, so that the welding head of the welding mechanism 5 can swing and flow between several welding stations 1.

[0047] In one embodiment, such as Figure 1 and Figure 7 As shown, there are two welding stations 1, and correspondingly, there are also two pressing mechanisms 2, each positioned above one of the two welding stations 1. Each pressing mechanism 2 is equipped with a temporary storage mechanism 4. Furthermore, there is one conveying mechanism 3 and one welding mechanism 5. One conveying mechanism 3 can feed materials to both welding stations 1, and one welding mechanism 5 can weld the parts to be welded at both welding stations 1.

[0048] It is worth noting that when using the welding equipment of this embodiment, the conveying mechanism 3 first loads the electrode plate onto the first welding station 1, then the conveying mechanism 3 loads the electrode mesh onto the electrode plate. Next, the pressing mechanism 2 presses the mesh, and the welding mechanism 5 performs the welding. Simultaneously, the conveying mechanism 3 can load the material onto the second welding station 1 and press it using the corresponding pressing mechanism 2. After welding at the first welding station 1 is completed, the welding mechanism 5 moves to the second welding station 1 for welding. At the same time, the conveying mechanism 3 moves to the first welding station 1, flips the single-sided welded part on the first welding station 1, and places it in the temporary storage mechanism 4. The pressing mechanism 2 then drives the temporary storage mechanism 4 to... After the single-sided welded part is placed at the first welding station 1, it moves upward and away. The conveying mechanism 3 feeds the electrode mesh onto the single-sided welded part, and the pressing mechanism 2 presses it again. At this time, the welding mechanism 5 moves to the first welding station 1 to weld again. At the same time, the conveying mechanism 3 performs a flipping operation and electrode mesh feeding operation on the second welding station 1. After the welding mechanism 5 completes the double-sided welding at the first welding station 1, it moves to the second welding station 1 to weld. At this time, the conveying mechanism 3 can unload the double-sided welded part at the first welding station 1, and after unloading, it can load it again. Then the conveying mechanism 3 can move to the second welding station 1 to unload and load the double-sided welded part again.

[0049] In one embodiment, such as Figure 1 As shown, the welding equipment also includes a frame 9, and several pressing mechanisms 2 are all mounted on the frame 9.

[0050] It is worth noting that during welding, welding station 1 and pressing mechanism 2 rotate synchronously to enable welding mechanism 5 to complete the circumferential welding of the electrode plate and electrode mesh. Specifically, welding station 1 and pressing mechanism 2 can be synchronously driven by a motor and gear structure.

[0051] In one embodiment, such as Figures 1 to 4 As shown, the conveying mechanism 3 includes a conveying drive structure 301, an mounting structure 302, an electrode plate picking assembly 303, and an electrode mesh picking assembly 304. The conveying drive structure 301 is connected to the mounting structure 302 for transmission, and both the electrode plate picking assembly 303 and the electrode mesh picking assembly 304 are mounted on the mounting structure 302. The conveying mechanism 3 has an electrode plate picking state and an electrode mesh picking state. In the electrode plate picking state, the conveying mechanism 3 picks up the electrode plates through the electrode plate picking assembly 303; in the electrode mesh picking state, the conveying mechanism 3 picks up the electrode mesh through the electrode mesh picking assembly 304.

[0052] When electrode plates need to be fed, the electrode plate feeding assembly 303 feeds the electrode plates, and the conveying drive structure 301 drives the mounting structure 302, along with the electrode plates, to move synchronously to the welding station 1 for feeding. When electrode mesh needs to be fed, the electrode mesh feeding assembly 304 feeds the electrode mesh, and the conveying drive structure 301 drives the mounting structure 302, along with the electrode mesh, to move synchronously to the welding station 1 for feeding. Therefore, the conveying mechanism 3 can feed both electrode plates and electrode mesh.

[0053] In one embodiment, such as Figure 2 and Figure 3 As shown, the electrode plate picking assembly 303 includes a first driving structure 3031 and an electrode plate picking structure 3032. The first driving structure 3031 is disposed on the mounting structure 302 and is adapted to drive the electrode plate picking structure 3032 to move. In the electrode plate picking state, the electrode plate picking structure 3032 protrudes from the side of the mounting structure 302 facing the electrode plate.

[0054] When picking up the electrode plate, the first driving structure 3031 drives the electrode plate picking structure 3032 to move toward the electrode plate and protrude from the mounting structure 302, which facilitates the picking up of the electrode plate.

[0055] It is worth noting that when the electrode mesh is being picked up, the electrode plate suction structure 3032 is retracted by the first drive structure 3031, thereby avoiding the electrode mesh picking process.

[0056] In one embodiment, such as Figure 3 As shown, the first driving structure 3031 includes a vertical driving part 30311 and a radial driving part 30312. The radial driving part 30312 is disposed on the mounting structure 302. The vertical driving part 30311 is connected to the driving end of the radial driving part 30312. The driving end of the vertical driving part 30311 is connected to the electrode plate absorption structure 3032.

[0057] The radial drive unit 30312 drives the vertical drive unit 30311, together with the electrode plate suction structure 3032, to move radially along the mounting structure 302, thereby adjusting the radial position of the electrode plate suction structure 3032 to match the size of the electrode plate to be suctioned; the vertical drive unit 30311 drives the electrode plate suction structure 3032 to move vertically, thereby achieving the suction of the electrode plate and avoiding the electrode mesh material handling process.

[0058] It is worth noting that by setting the radial drive unit 30312, the welding equipment can be compatible with different product specifications with electrode diameters ranging from 1000mm to 2500mm.

[0059] It should be noted that, according to the diameter of the electrode plate to be welded, the electrode plate absorbing structure 3032 is adjusted to an appropriate position by the radial drive part 30312. During the welding process, there is no need to readjust the radial position of the electrode plate absorbing structure 3032 again; adjustment is only required after the change of shape.

[0060] In one embodiment, the vertical drive unit 30311 and the radial drive unit 30312 may be linear drive components such as cylinders.

[0061] In one embodiment, such as Figure 2 As shown, several electrode plate feeding assemblies 303 are arranged at intervals along the circumference of the mounting structure 302.

[0062] In one embodiment, such as Figure 2 and Figure 4 As shown, the electrode mesh feeding assembly 304 includes a second drive structure 3041, an electrode mesh picking structure 3042, and an electrode mesh pressing structure 3043. The second drive structure 3041 is disposed on the mounting structure 302 and is adapted to drive the electrode mesh picking structure 3042 to move radially along the mounting structure 302. The picking end of the electrode mesh picking structure 3042 and the pressing end of the electrode mesh pressing structure 3043 are adapted to be respectively disposed on opposite sides of the electrode mesh.

[0063] The electrode mesh is lifted along the radial direction by the electrode mesh lifting structure 3042, and then the electrode mesh is pressed by the electrode mesh pressing structure 3043, thereby achieving clamping and fixing of the electrode mesh and ensuring the stability of electrode mesh material picking.

[0064] In one embodiment, such as Figure 4 As shown, the scooping mesh structure 3042 includes a connecting block 30421, an extension plate 30422, a vertical plate 30423, and a hook end 30424. The driving end of the second driving structure 3041 is connected to the connecting block 30421. The first end of the extension plate 30422 is connected to the side of the connecting block 30421 away from the second driving structure 3041. The upper end of the vertical plate 30423 is connected to the second end of the extension plate 30422. The lower end of the vertical plate 30423 extends downward to form an installation structure 302. The hook end 30424 is located at the lower end of the vertical plate 30423 and extends towards the installation structure 302, forming a scooping end.

[0065] In one embodiment, such as Figure 4 As shown, the electrode grid structure 3043 includes a pressing block 30431 and a pressing block driving part 30432. The pressing block driving part 30432 is disposed on the electrode grid structure 3042. The pressing block driving part 30432 is adapted to drive the pressing block 30431 to move vertically. The pressing block 30431 passes through the extension plate 30422 and corresponds to the hook end 30424.

[0066] The pressing block drive unit 30432 is set on the electrode mesh structure 3042, and the pressing block 30431 passes through the extension plate 30422, so that the pressing block 30431 and the hook end 30424 can be matched accordingly, thereby improving the stability of the electrode mesh material picking process.

[0067] In one embodiment, such as Figure 4 As shown, the conveying mechanism 3 also includes a position detection unit 305, which is electrically connected to the conveying drive structure 301. The position detection unit 305 is adapted to detect the relative position of the pole mesh structure 3042 and the pole mesh.

[0068] When the position detection unit 305 detects that the position of the pole-collecting mesh structure 3042 corresponds to that of the pole mesh, it sends a signal to the conveying drive structure 301 to stop the conveying drive structure 301, thus ensuring the accuracy of the relative position of the pole-collecting mesh structure 3042 and the pole mesh.

[0069] In one embodiment, the position detection unit 305 is an infrared proximity switch.

[0070] In one embodiment, such as Figure 2 As shown, several of the mesh material handling components 304 are arranged at circumferential intervals along the mounting structure 302.

[0071] It should be noted that by setting several electrode plate feeding components 303 and electrode mesh feeding components 304 at circumferential intervals along the mounting structure 302, the stability of feeding the electrode plate and electrode mesh is further ensured, while eliminating vertical unevenness during feeding, so that the electrode plate and electrode mesh remain horizontal.

[0072] In one embodiment, the conveying drive structure 301 is a robotic arm with three-dimensional visual positioning capabilities.

[0073] In one embodiment, such as Figure 5 and Figure 6 As shown, the temporary storage mechanism 4 includes a third driving structure 401, a connecting structure 402, and a temporary storage adsorption structure 403. The third driving structure 401 is disposed on the pressing mechanism 2. The connecting structure 402 connects the driving end of the third driving structure 401 and the temporary storage adsorption structure 403. The third driving structure 401 is adapted to drive the connecting structure 402 to rotate and drive the temporary storage adsorption structure 403 to rotate. The temporary storage adsorption structure 403 has an adsorption position and a clearance position. In the adsorption position, the temporary storage adsorption structure 403 is not higher than the pressing surface of the pressing mechanism 2. In the clearance position, the temporary storage adsorption structure 403 is located above the pressing mechanism 2.

[0074] When it is necessary to temporarily store a single-sided welded part, the third drive structure 401 drives the connecting structure 402 to rotate, so that the connecting structure 402 moves the temporary storage adsorption structure 403 to below the pressing surface of the pressing mechanism 2, thereby facilitating the temporary storage of the single-sided welded part under the pressing mechanism 2 and making it easy to place the single-sided welded part back on the welding station 1. When it is necessary to use the pressing mechanism 2 to press the part to be welded, the third drive structure 401 drives the connecting structure 402 to rotate, so that the connecting structure 402 moves the temporary storage adsorption structure 403 to above the pressing mechanism 2, avoiding the temporary storage adsorption structure 403 from affecting the pressing of the pressing mechanism 2 and the welding of the welding mechanism 5.

[0075] It is worth noting that both the electrode plate suction structure 3032 and the temporary adsorption structure 403 are electromagnetic chucks. When the coil of the electromagnetic chuck is energized, the electromagnetic chuck can generate a suction force, thereby picking up and fixing the electrode plate or the single-sided welded part.

[0076] In one embodiment, such as Figure 6 As shown, the connecting structure 402 includes a lever 4021 and a connecting rod 4022. One end of the lever 4021 is hinged to the driving end of the third driving structure 401, and the other end of the lever 4021 is connected to the temporary adsorption structure 403 through the connecting rod 4022. The lever 4021 and the fixed part of the third driving structure 401 have a hinge point, which is located between the two ends of the lever 4021.

[0077] When one end of the lever 4021 is driven to rotate by the third drive structure 401, the lever 4021 rotates around the hinge point, thereby causing the other end of the lever 4021 to drive the connecting rod 4022 and the temporary adsorption structure 403 to rotate synchronously.

[0078] In one embodiment, the third drive structure 401 is a cylinder, and the drive end of the third drive structure 401 is extendable.

[0079] It is worth noting that the fixing part of the third drive structure 401 mentioned above can be the outer shell of the third drive structure 401, or it can be an additional fixing block or other structure.

[0080] In one embodiment, such as Figure 5 As shown, several temporary storage mechanisms 4 are arranged at circumferential intervals along the pressing mechanism 2. Therefore, the stability of adsorption on single-sided welded parts can be guaranteed.

[0081] In one embodiment, such as Figure 5 As shown, the pressing mechanism 2 includes a pressing drive structure 201 and a pressure plate 202. The pressing drive structure 201 is connected to the pressure plate 202 in a transmission manner, and the temporary storage mechanism 4 is disposed on the pressure plate 202.

[0082] In one embodiment, such as Figure 1 and Figure 7 As shown, the welding equipment also includes a plate loading station 6, a wire mesh loading station 7, and a finished product unloading station 8. The conveying mechanism 3 is movable and can be set up to correspond to several welding stations 1, plate loading stations 6, wire mesh loading stations 7, and finished product unloading stations 8.

[0083] It is worth noting that electrode plate loading station 6 is used to stack electrode plates, electrode mesh loading station 7 is used to stack electrode mesh, and finished product unloading station 8 is used to stack double-sided welded parts that have been welded.

[0084] In one embodiment, such as Figure 1 and Figure 7 As shown, several welding stations 1, electrode mesh loading stations 7, electrode plate loading stations 6, and finished product unloading stations 8 are arranged sequentially around the outer periphery of the conveying mechanism 3. Therefore, it facilitates the loading of electrode plates and electrode meshes and the unloading of finished products by the conveying mechanism 3, optimizes the movement path of the conveying mechanism 3, facilitates the flow of the conveying mechanism 3 between various stations, and further improves processing efficiency.

[0085] It should be noted that you should refer to [link / reference]. Figure 7 Two welding stations 1, as well as electrode wire feeding station 7, electrode plate feeding station 6, and finished product unloading station 8, are arranged in a counterclockwise direction around the outer periphery of the conveying mechanism 3, thus forming a "five-ring" arrangement.

At this time, the robot moves to the first welding station 1, picks up the single-sided welded part and moves it to the free space to rotate 180° to flip it over. The robot transports the flipped single-sided welded part to the temporary storage mechanism 4. The third drive structure 401 drives the connecting structure 402 and drives the temporary storage adsorption structure 403 to rotate to the bottom of the pressing mechanism 2 to adsorb and temporarily store the single-sided welded part. The robot moves towards the electrode mesh loading station 7 to pick up the material. The pressing mechanism 2 drives the single-sided welded part to move downward and places the single-sided welded part on the electrode mesh loading station 7. At the corresponding welding station 1, the third drive structure 401 drives the connecting structure 402 to rotate the temporary adsorption structure 403 to above the pressing mechanism 2.
