Description

Technical Field

[0002] Hydrogen production equipment is a device used to produce hydrogen. It mainly decomposes water into hydrogen and oxygen through electrolysis. Hydrogen production equipment plays an important role in promoting the use of clean energy and sustainable development. With the continuous advancement of technology and the continuous expansion of application fields, the development prospects of hydrogen production equipment will be broader.

[0003] The electrode plate is one of the key components of the hydrogen production equipment. It mainly plays the role of conducting electrons and blocking the cathode alkali liquid and the anode alkali liquid. Structurally, in order to increase the current density and reduce the energy consumption of hydrogen production, the electrode plate is designed to be an inner plate and a pole frame, which needs to be assembled by laser welding. When the existing welding device is in use, the pole frame needs to be positioned, usually by pressing and positioning the top of the pole frame with bolts and pressure plates, but six bolts are required for multi-angle positioning. Each time it is installed, each bolt needs to be adjusted separately. When the height adjustment of the pressure plate on one of the bolts is inconsistent with the height of the other pressure plates, it is easy to cause the angle of the pole frame to be skewed, so that the welding gap between the pole frame and the inner plate increases, and the pole frame and the inner plate cannot be accurately welded, which reduces the production quality of the electrode plate.

[0032] The user places the pole frame 6 in the housing 2, and rotates the annular turntable 10, so that the annular turntable 10 pushes the slider 13 on the slide bar 12 through the arc groove 11 to move horizontally along the inner side of the support frame 19, so that the slider 13 drives the mounting block 14 to move through the telescopic rod 15, and the mounting block 14 drives the welding pressing block 9 to move along the groove on the top ring 8. At the same time, the welding pressing block 9 drives the two pulleys 17 on its outer side to move along the inclined groove 18 on the top ring 8, so that the welding pressing block 9 moves in a downward inclined direction while moving horizontally, and the welding pressing block 9 can contact the top of the pole frame 6, so that multiple welding pressing blocks 9 can synchronously press and position the pole frame 6, solve the problem that the existing welding device easily causes the pole frame 6 to be skewed, and facilitate the rapid assembly and welding of the pole frame 6 and the inner plate 7, thereby achieving the effect of rapid positioning welding.

[0033] See also Figure 3-Figure 7The position-correcting mechanism 4 shown in the figure includes a push rod 25 fixedly mounted on the end of the slide bar 12 away from the slider 13. The end of the push rod 25 away from the slide bar 12 is fixedly connected to a prismatic rod 26. A slide cylinder 27 is slidably sleeved on the outer side of the prismatic rod 26. A long groove for limiting the sliding of the push rod 25 is provided on the outer side of the slide cylinder 27. A push block 28 is fixedly connected to the top of the slide cylinder 27. The push block 28 is a cylindrical structure. The push block 28 contacts the inner circle of the pole frame 6 to facilitate the inner side of the pole frame 6 to correct the position of the pole frame 6. The end of the prismatic rod 26 away from the push rod 25 is fixedly connected to A moving block 29, the outer side of which is provided with a slide frame 30 fixedly mounted on the top of the device base 1, the inner side of the slide frame 30 is fixedly connected with two guide rods 31 slidingly penetrating the moving block 29, so as to facilitate the smooth movement of the prismatic rod 26, the top of the slide frame 30 is fixedly connected with two support plates 32 symmetrically distributed on both sides of the slide cylinder 27, the outer side of the slide cylinder 27 is rotatably mounted with two symmetrically distributed pulleys 33, the outer side of the support plate 32 is provided with an inclined groove 34 for the pulley 33 to limit the sliding, so that the slide cylinder 27 can be tilted downward or upward when moving horizontally;

[0034] When the welding pressing block 9 moves upwardly, the sliding rod 12 pulls the pushing rod 25 to move, and the pushing rod 25 drives the moving block 29 on the prismatic rod 26 to move along the guide rod 31 on the sliding frame 30, so that the prismatic rod 26 pulls the pushing block 28 to move synchronously through the sliding cylinder 27. At the same time, the two pulleys 33 on the sliding cylinder 27 move upwardly along the inclined groove 34 on the supporting plate 32, so that the pushing block 28 is in an inclined upward moving state, and the pushing block 28 can move toward the inner side of the pole frame 6, so that the six pushing blocks 28 can push the inner side of the pole frame 6 synchronously, and the position of the pole frame 6 can be corrected, so that the pole frame 6 is in the middle position in the shell 2, which is convenient for the inner plate 7 to quickly align with the inner frame of the pole frame 6. When the welding pressing block 9 moves downward, the pushing block 28 can move downwardly and away from the pole frame 6, preventing the pushing block 28 from causing obstruction to the inner plate 7, which is convenient for quickly welding between the pole frame 6 and the inner plate 7, thereby achieving the effect of improving the welding accuracy.

[0035] See also Figure 3 and Figure 8The spring mechanism 5 shown in the figure includes a placement plate 35 arranged below the inner plate 7 for placing the inner plate 7. A telescopic rod 36 is fixedly connected between the bottom of the placement plate 35 and the device base 1. A placement ring 37 is fixedly installed on the outer side of the placement plate 35. The placement ring 37 is located below the pole frame 6 to provide support for the bottom of the pole frame 6 for easy welding. A sliding cavity 38 for limiting the sliding of the push block 28 is opened on the inner side of the placement ring 37. A gasket 39 is fixedly connected to the top of the placement ring 37. The top of the gasket 39 is fixedly connected to the top of the gasket 39. A plurality of anti-skid grooves equidistantly distributed in an annular shape are provided on the bottom of the placement ring 37, so as to prevent the position of the pole frame 6 from being offset when the push block 28 is away from the pole frame 6. A plurality of telescopic rods 3 40 equidistantly distributed in an annular shape are fixedly connected between the bottom of the placement ring 37 and the device base 1. A spring 2 41 is provided on the outer side of the telescopic rod 3 40. The spring 2 41 is fixedly installed between the placement ring 37 and the device base 1, so that when the welding pressing block 9 is pressed against the top of the pole frame 6, the spring 2 41 buffers the pressure on the placement ring 37.

[0036] When the welding pressing block 9 presses the pole frame 6 to position, the pressure of the welding pressing block 9 pushes the pole frame 6 to move downward, and the pole frame 6 pushes the placement ring 37 to move downward, so that the placement ring 37 and the placement plate 35 compress the spring 2 41, providing a buffer for the pressure of the welding pressing block 9, preventing the welding pressing block 9 from being pressed too hard, and improving the safety of positioning the pole frame 6. At the same time, the elasticity of the spring 2 41 can make the pole frame 6 close to the welding pressing block 9, and after the push block 28 corrects the position of the pole frame 6, the anti-slip groove on the gasket 39 can increase the friction between the gasket 39 and the bottom of the pole frame 6, preventing the position of the pole frame 6 from being offset. After the welding pressing block 9 is away from the pole frame 6, the rebound force of the spring 2 41 is used to pop the formed pole plate upward, which is convenient for quick discharge, thereby achieving the effect of safe positioning and easy discharge.

[0037] Working principle: First, the user places the pole frame 6 on the placement ring 37 and rotates the annular turntable 10. The annular turntable 10 pushes the slider 13 on the slide rod 12 to move horizontally along the inner side of the support frame 19 through the arc groove 11, so that the slider 13 drives the mounting block 14 to move through the telescopic rod 15, and the mounting block 14 drives the welding pressure block 9 to move along the groove on the top ring 8. The welding pressure block 9 drives the two pulleys 17 on its outer side to move along the inclined groove 18 on the top ring 8, so that the welding pressure block 9 moves to the top of the top ring 8. The push rod 25 moves in an upward inclined direction, so that the welding pressing block 9 is away from the pole frame 6. At the same time, the slide rod 12 pulls the push rod 25 to move synchronously, and the push rod 25 drives the moving block 29 on the prismatic rod 26 to move along the guide rod 31 on the slide frame 30, so that the prismatic rod 26 pulls the push block 28 to move synchronously through the slide cylinder 27. At the same time, the two pulleys 33 on the slide cylinder 27 move upward along the inclined groove 34 on the support plate 32, so that the push block 28 moves obliquely upward along the slide cavity 38 on the placement ring 37, and the push block 28 and the pole frame 6, so that the six push blocks 28 can push the inner side of the pole frame 6 synchronously, and the position of the pole frame 6 can be corrected so that the center of the pole frame 6 is aligned with the circle of the placement ring 37. Then, the user rotates the annular turntable 10 in the opposite direction, and the push block 28 can move downward and tilt away from the inner side of the pole frame 6. At the same time, the welding pressure block 9 moves downward and tilts to press and position the top of the pole frame 6. The spring 2 41 is used to provide a buffer for the movement of the welding pressure block 9 to prevent the pressure of the welding pressure block 9 from being too large. After the welding pressure block 9 is pressed against the pole frame 6, the user places the inner plate 7 on the placement plate 35 so that the inner plate 7 is in the inner circle position of the pole frame 6. Finally, the user welds the pole frame 6 and the inner plate 7. After the welding is completed, the user rotates the annular turntable 10 to make the pole plate formed by the welding pressure block 9, and the rebound force of the spring 2 41 is used to make the placement ring 37 and the placement plate 35 push the formed pole plate to be discharged, thereby achieving the effect of quickly assembling the pole frame 6 and the inner plate 7, and improving the accuracy and safety of welding.

[0038] Example 2: Please refer to Figure 2-Figure 5 , this embodiment further explains Example 1, the adjustment component 20 shown in the figure includes six pull plates 21 fixedly installed on the outside of the annular turntable 10 in an annular shape and equidistant therefrom, a sliding groove for the pull plates 21 to limit the sliding movement is provided on the outside of the outer shell 2, a handle 22 is fixedly installed on the end of the pull plate 21 away from the annular turntable 10, for the convenience of rotating the annular turntable 10, six positioning plates 23 distributed in an annular shape and equidistant therefrom are provided on the top and bottom of the annular turntable 10, the positioning plates 23 are fixedly installed on the inner side of the outer shell 2 to provide positioning for the annular turntable 10, a grip tube 24 is rotatably installed on the outside of the handle 22 to improve the convenience of pulling the handle 22, a plurality of balls 42 distributed in an annular shape and equidistant therefrom are rotatably installed on the outside of the annular turntable 10, a moving groove for the balls 42 to limit the sliding movement is provided on the side of the positioning plate 23 close to the annular turntable 10, for the convenience of rotating the annular turntable 10.

[0039] In this embodiment: the user can hold the grip 24 and pull the handle 22 to move, so that the handle 22 drives the annular turntable 10 to rotate along the outer side of the positioning plate 23 through the pull plate 21, and the ball 42 on the annular turntable 10 moves along the moving groove on the positioning plate 23, which is convenient for the user to quickly press and position the pole frame 6, thereby improving the convenience of installing the pole frame 6.

[0040] Example 3: Please refer to Figure 3-Figure 6 This embodiment further illustrates other embodiments. The outer side of the slide bar 12 in the figure is rotatably installed with two positioning shafts 43 symmetrically distributed at the top and bottom of the annular turntable 10, which is convenient for the slide bar 12 to move smoothly on the inner side of the arc groove 11. The bottom of the welding block 9 is fixedly installed with an anti-skid plate 44 to prevent the welding block 9 from slipping when it contacts the pole frame 6. The inclination angle of the second inclined groove 34 is smaller than the inclination angle of the first inclined groove 18, which is convenient for the push block 28 to quickly move away from the pole frame 6. A U-shaped plate 45 for the placement ring 37 to move and contact is fixedly connected between the tops of the two support plates 32, providing a limit support for the downward movement of the placement ring 37.

[0041] In this embodiment: when the welding block 9 presses the pole frame 6 to move downward, the anti-slip plate 44 at the bottom of the welding block 9 can improve the stability of pressing the pole frame 6, and the pole frame 6 pushes the placement ring 37 to move downward. The U-shaped plate 45 on the support plate 32 can provide a limit and support for the movement of the placement ring 37, preventing the user from pressing the pole frame 6 during welding, causing the pole frame 6 to move excessively downward, thereby improving the safety during welding. Moreover, since the inclination angle of the second inclined groove 34 is smaller than the inclination angle of the first inclined groove 18, when the welding block 9 moves, the push block 28 can quickly move away from the inner side of the pole frame 6, and when the slide bar 12 moves, it can move smoothly along the inner side of the arc groove 11 through the positioning shaft 43 to prevent skewing.
