Description

Technical Field

[0001] The invention relates to the technical field of welding, and in particular to a polar plate welding device for a water electrolysis hydrogen production electrolyzer. Background Art

[0002] The electrode plates of the electrolytic cell are composed of an electrode frame and a mastoid plate. The electrode frame is a circular ring structure, and the mastoid plates are circular structures. The inner diameter of the electrode frame is slightly larger than the inner diameter of the mastoid plate. When in use, the two need to be welded together.

[0003] In the traditional way, the welding of the two is generally done manually. As the size of electrolytic cells is getting bigger and bigger, the size of the plates is also greatly increased, which leads to a huge amount of manual welding work, which in turn easily leads to welding errors and eventually causes problems such as welding deformation.

[0004] In this regard, the use of automated welding is the development trend of the existing technology. For example, the Chinese patent with application number "CN202310964975.5" discloses "a welding system and method for hydrogen alkaline electrolyzers", and its technical solution is "a welding system and method for hydrogen alkaline electrolyzers, used for welding the pole frame and pole plate of hydrogen alkaline electrolyzers, the system includes a moving mechanism and a rotating platform, wherein the moving mechanism is provided with a welding head, a wire feeding assembly and a weld tracking assembly, the welding head is used for laser welding of the pole frame and the pole plate, the wire feeding assembly is used for synchronous wire feeding during laser welding, and the weld tracking assembly is used for weld tracking during laser welding; the rotating platform is provided with a tooling fixture, the tooling fixture is used to fix the pole frame and the pole plate, and the rotating platform drives the pole frame and the pole plate to rotate for welding during welding. The present invention improves the efficiency and quality of electrolytic cell welding processing and reduces heat input deformation".

[0005] Another example is the Chinese patent with application number "CN202410459397.4", which discloses "a welding device for the pole frame-pole plate or mastoid plate of an alkaline water hydrogen production electrolyzer", and its technical solution is "including a welding robot and auxiliary equipment all arranged on the ground, the auxiliary equipment including a rotary welding table, a shading device and a clamping device; a plurality of shading devices are arranged on the periphery of the rotary welding table; the rotary welding table includes a rotary table, a rotary frame, an inner positioning assembly and an outer positioning assembly, a rotary frame is arranged above the rotary table, and an inner positioning assembly and an outer positioning assembly are coaxially arranged inside and outside the rotary frame; the inner positioning assembly includes an inner support plate and a positioning block with a positioning bolt, and the outer positioning assembly includes an outer support plate, a pole frame limit block and a clamping unit; the shading device includes a base frame and a shading plate that can be lifted and lowered on the base frame, and the clamping device includes a lifting mechanism and a clamping mechanism controlled by the lifting mechanism. The present invention can fix and accurately position the pole frame, pole plate or mastoid plate to ensure the stability of the workpiece during rotary welding, thereby improving the quality of welding."

[0006] Although automated welding has greatly improved production speed and welding accuracy, it is limited by the size errors of the pole frame and mastoid plate. There will still be errors in the welding process, which will cause the weld to deform, and a certain degree of trimming is required. However, neither of the above two solutions provides a relevant solution. Summary of the invention

DETAILED DESCRIPTION

[0031] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0032] Example:

[0033] like Figure 1-9 As shown, a water electrolysis hydrogen production electrolytic cell plate welding device comprises a laser welding device 1, a support mechanism 2, a grinding mechanism 3 and a reversing transport mechanism, wherein the laser welding device 1, the grinding mechanism 3 and the reversing transport mechanism are all arranged around the support mechanism 2. When the device is in use, the frame and the mastoid plate are first placed on the support mechanism 2, and then the support mechanism 2 drives the frame and the mastoid plate to rotate, and at the same time the laser welding device 1 is started to weld the gap between the frame and the mastoid plate, and after the welding is completed, the defect points are recorded during the welding process, and after the weld is cooled, the grinding mechanism 3 is started to grind the recorded defect points in a targeted manner, and after the grinding is completed, the welded plate is removed by the reversing transport mechanism and sent to the stacking area.

[0034] The laser welding device 1 is a mature prior art, which consists of a multi-axis robot arm and a laser welding head, wherein a visual probe is installed on one side of the laser welding head for correcting the welding angle and recording welding defects. Since the laser welding mechanism is a mature technology and it is not the invention point of this solution, it will not be described in detail in this solution.

[0035] In the present embodiment, the grinding mechanism 3 includes a limit frame 31, which is located on one side of the support mechanism 2. An extrusion shell 32 is installed on the limit frame 31, and the extrusion shell 32 includes an upper shell 321 and a lower shell 322 distributed up and down, and the bottom of the upper shell 321 is rotatably connected to the top of the lower shell 322. In the present embodiment, the weight of the lower shell 322 is extremely large, and its purpose is to fix the mastoid plate to prevent it from shifting and causing the weld to deviate. In the present embodiment, in order to prevent the lower shell 322 from hindering the support mechanism 2 from driving the mastoid plate to rotate, the lower shell 322 needs to rotate synchronously with the support mechanism 2. In order to avoid obstruction by the upper shell 321, the upper shell 321 is rotatably connected to the lower shell 322.

[0036] In order to facilitate the up and down movement of the extrusion shell 32, a first support arm 33 and a support column 34 are installed on the top of the upper shell 321. The first support arm 33 is located between the upper shell 321 and the limit frame 31. The first support arm 33 can move on the limit frame 31. At this time, the extrusion shell 32 will follow the first support arm 33 to move up and down. In order to facilitate the grinding of the weld, a second support arm 341 is installed on one side of the support column 34. A grinding roller 342 is hoisted at one end of the second support arm 341 away from the support column 34. A first motor 345 is installed on one side of the grinding roller 342. The grinding roller 342 is located above the weld, and the side wall of the grinding roller 342 contacts the weld. At this time, the first motor 345 is started, and the first motor 345 drives the grinding roller 342 to rotate, thereby achieving the grinding of the weld defect points.

[0037] In order to facilitate the grinding of the weld, we need to control the distance between the weld and the grinding roller 342. For this purpose, the support column 34 is located between the central area of ​​the upper shell 321 and the side edge of the upper shell 321. A first telescopic cylinder 343 is provided between the grinding roller 342 and the second support arm 341. A splash-proof shell 344 is provided between the grinding roller 342 and the first telescopic cylinder 343. The splash-proof shell 344 is arranged around the grinding roller 342, and the grinding roller 342 is rotatably connected to the splash-proof shell 344. The first motor 345 is installed at one end of the splash-proof shell 344, and the telescopic end of the first telescopic cylinder 343 is connected to the outer wall of the splash-proof shell 344. The distance between the grinding roller 342 and the weld is adjusted by driving the grinding roller 342 to move up and down through the first telescopic cylinder 343.

[0038] In order to facilitate multi-directional grinding of the weld, a second motor 346 is installed at one end of the second support arm 341 away from the support column 34, and the power end of the second motor 346 is connected to one end of the first telescopic cylinder 343 away from the grinding roller 342. The second motor 346 can drive the grinding roller 342 to rotate by driving the first telescopic cylinder 343 to rotate, thereby achieving multi-directional grinding of the weld by the grinding roller 342.

[0039] like Figure 3 As shown, in order to facilitate multi-angle grinding of welds, the end of the second support arm 341 away from the support column 34 is hinged to the third support arm 347, the second motor 346 is located at the end of the third support arm 347 away from the second support arm 341, and a second telescopic cylinder 349 is arranged between the second support arm 341 and the first telescopic cylinder 343. One end of the second telescopic cylinder 349 is hinged to the second support arm 341, and the end of the second telescopic cylinder 349 away from the second support arm 341 is hinged to the adapter shell 348, and the first telescopic cylinder 343 is rotatably arranged in the adapter shell 348. The second telescopic cylinder 349 pushes and pulls the adapter shell 348 by telescoping. Since the third support arm 347 is hinged to the second support arm 341, the second telescopic cylinder 349 can adjust the angle between the second support arm 341 and the third support arm 347 during operation, thereby adjusting the inclination angle of the grinding roller 342. In addition, in the above scheme, the first telescopic cylinder 343 can adjust the grinding roller 342 to move up and down, and the second motor 346 can drive the grinding roller 342 body to rotate, so that the grinding roller 342 can grind the weld at multiple angles and directions. In order to prevent the second telescopic cylinder 349 from hindering the second motor 346 from hindering the rotation of the first telescopic cylinder 343, the present scheme introduces the adapter shell 348, and the first telescopic cylinder 343 is installed in the adapter shell 348, and the two are rotatably connected.

[0040] In order to facilitate the placement of the pole frame and the mastoid plate, we need to move the extrusion shell 32 up and down. To this end, a third motor 311 is provided at the top of the limit frame 31, and the power end of the third motor 311 is connected to the first screw rod 312, and the first screw rod 312 extends toward the bottom of the limit frame 31. A first slide bar 313 is provided on one side of the first screw rod 312, and the first slide bar 313 is parallel to the first screw rod 312. The end of the first support arm 33 away from the upper shell 321 is respectively threadedly connected to the first screw rod 312 and slidably connected to the first slide bar 313. The third motor 311 drives the first screw rod 312 to rotate. Since the first screw rod 312 is threadedly connected to the first support arm 33, and the first slide bar 313 limits the first support arm 33, the first support arm 33 will move up and down with the forward and reverse rotation of the first screw rod 312, and at this time, it can drive the extrusion plate to move up and down.

[0041] In order to facilitate the identification of weld defects, a visual acquisition head 340 is provided on one side of the third support arm 347. The visual acquisition head 340 will work together with the visual probe of the laser welding device 1, and the processing system will compare the images captured by the two to accurately locate the weld defects.

[0042] During the grinding process, the grinding roller 342 will produce debris. In order to prevent the debris from accumulating on the plate, we can send the debris to the outside of the plate through high-speed airflow. To this end, a plurality of air outlets 323 are provided on the outer wall of the lower shell 322, and an air pump 325 is installed on the top of the limit frame 31. A first pipe 324 is provided between the air pump 325 and the air outlet 323. The air pump 325 sends the high-speed airflow to the air outlet 323 through the first pipe 324. When the high-speed airflow flows, the debris generated during the grinding and welding processes will be blown to the outside.

[0043] Preferably, an annular air pipe 326 is provided in the lower shell 322 , the air outlet 323 is communicated with the annular air pipe 326 , and one end of the first pipeline 324 away from the air pump 325 is communicated with the annular air pipe 326 .

[0044] In this solution, the lower shell 322 will rotate with the mastoid plate, while the upper shell 321 and the grinding roller 342 on the upper shell 321 will not rotate with the lower shell 322. For this reason, the outer contour size of the upper shell 321 is smaller than the outer contour size of the lower shell 322. A slot is provided at the top of the lower shell 322, and a base 327 is provided at the bottom of the upper shell 321. The slot is provided around the base 327, and a support ring groove 35 is provided at the bottom of the slot. The support ring groove 35 includes an inner ring body 352 and an outer ring body 351. A plurality of balls 353 are provided between the inner ring body 352 and the outer ring body 351, and a partial area of ​​the balls 353 is in contact with the bottom of the base 327.

[0045] The existing laser welding technology is generally double-sided welding, that is, welding one side of the plate, and then welding the other side of the plate. However, due to power fluctuations and external temperature, the probability of defects in the weld on the other side of the plate is greatly increased. Therefore, we need to flip the plate and grind the weld on the other side. Figure 1 , 5As shown, the reverse transport mechanism includes a first clamping assembly 41 and a second clamping assembly 42, and the support mechanism 2 is located between the first clamping assembly 41 and the second clamping assembly 42. The structure of the first clamping assembly 41 is the same as that of the second clamping assembly 42. The first clamping assembly 41 includes a horizontally arranged limited track 411, a movable seat 412 is installed in the limited track 411, and a fixed column 413 is installed on the top of the movable seat 412. The fixed column 413 is vertically provided with a fixed groove 414 on one side of the support mechanism 2, and a fixed groove 414 is vertically provided in the fixed groove 414. There are a second screw rod 415, a second sliding rod and a clamping arm 417. A fourth motor 416 is installed on the top of the fixed column 413. The power end of the fourth motor 416 is connected to one end of the second screw rod 415. The other end of the second screw rod 415 is rotatably connected to the bottom of the fixed groove 414. The second screw rod 415 is threadedly connected to the clamping arm 417. The second sliding rod is slidably connected to the clamping arm 417. A clamping hand 418 is installed at one end of the clamping arm 417 facing the support mechanism 2, and a fifth motor 419 is installed between the clamping hand 418 and the clamping arm 417.

[0046] In the above scheme, the movable seat 412 drives the fixed column 413 to slide to the specified position in the limiting track 411, and then the fourth motor 416 drives the clamping arm 417 to a suitable position through the second screw rod 415, and then the clamping hand 418 clamps the welded plate, and then the fourth motor 416 drives the clamping arm 417 to a certain height through the second screw rod 415 to prevent other mechanisms from hindering the flipping of the plate. Finally, the fifth motor 419 drives the clamping hand 418 to rotate, and after the flipping is completed, the fourth motor 416 drives the clamping arm 417 to descend, and the clamping hand 418 places the plate on the support mechanism 2 again.

[0047] In order to conveniently control the distance between the clamping hand 418 and the electrode plate, the clamping arm 417 is a telescopic cylinder.

[0048] The gripper 418 in this solution is also an existing mature technology such as a hydraulic gripper 418, an electric gripper 418, etc., so no further elaboration is given.

[0049] like Figure 6-9As shown, in order to facilitate the support mechanism 2 to drive the plate to rotate, the support mechanism 2 includes a base 21 and a positioning seat 22, one end of the positioning seat 22 is rotatably set in the base 21, and the positioning seat 22 is sequentially provided with a support platform 221, a positioning shell 222 and a positioning platform 223 from top to bottom, a plurality of electric telescopic cylinders 224 are installed between the support platform 221 and the positioning shell 222, and a gear mechanism 225 is arranged on the side wall of the positioning shell 222; the base 21 has an internal positioning groove 212 and a plurality of power motors 211, and the positioning platform 223 is rotatably set in the positioning groove 212, and a power rod 213 is installed at the power end of the power motor 211, and a power gear 214 meshing with the gear mechanism 225 is installed on the power rod 213. The power motor 211 drives the power gear 214 to drive the gear mechanism 225 to rotate, and at this time, the positioning seat 22 will rotate with the power gear 214, so the plate on the support platform 221 will also rotate with it.

[0050] The electric telescopic cylinder 224 in this solution drives the support platform 221 to move up and down, and its purpose is to assist the flipping transport mechanism to flip the plate. Of course, this design can also fine-tune the position of the plate according to the thickness of the plate to facilitate welding and grinding.

[0051] In order to facilitate the support platform 221 to rotate along with the positioning shell 222 , a limiting protrusion 226 is provided on the side wall of the support platform 221 , and a limiting groove 227 cooperating with the limiting protrusion 226 is provided on the inner wall of the positioning shell 222 .

[0052] In order to facilitate clamping and fixing the pole frame, the support platform 221 includes a first platform 23, a second platform 24 and a third platform 25. The first platform 23 and the third platform 25 are symmetrically arranged with respect to the second platform 24. The tops of the first platform 23 and the third platform 25 are provided with a plurality of L-shaped clamping platforms 26 and clamping grooves 27 matched with the clamping platforms 26. A third screw rod 261 and a third slide rod 262 arranged in parallel are installed in the clamping groove 27. A sixth motor 263 is installed at one end of the third screw rod 261 away from the second platform 24. A fixing block 264 is installed at one end of the third screw rod 261 facing the second platform 24. Both ends of the third slide rod 262 are provided with fixing blocks 264. The third screw rod 261 is threadedly connected to the bottom of the clamping platform 26, and the third slide rod 262 is slidably connected to the bottom of the clamping platform 26. A connecting arm is provided between the second platform 24 and the first and third platforms 23 and 25. The pole frame will be placed on the L-shaped clamping platform 26, and the multiple clamping platforms 26 will move toward the second platform 24. At this time, the multiple clamping platforms 26 will clamp the pole frame, thereby completing the fixation of the pole frame. At the same time, this design can also clamp pole frames of different sizes, expanding the application range of the entire device.

[0053] There is an escape area between the first platform 23 and the second platform 24 to facilitate the gripper 418 to grip the electrode plate.

[0054] In order to prevent the pole frame from deflecting after clamping, the clamping platforms 26 are arranged around the same circle.

[0055] In summary, this solution has the following advantages: First, after the laser welding equipment 1 completes welding, the grinding roller 342 can grind the weld defects. Second, through the mutual linkage of the second motor 346, the first telescopic cylinder 343, the second telescopic cylinder 349 and the third support arm 347, the grinding roller 342 can grind the weld defects in multiple directions and angles. Third, the flipping and transporting mechanism cooperates with the support platform 221 that moves up and down, which facilitates the flipping of the plate, so that the weld on the other side of the plate can also be polished.

[0056] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by ordinary technicians in this field based on the above-mentioned concepts without creative work are all within the protection scope of the present invention.
