Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Such as Figures 1 to 10As shown in the figure, the present invention provides a nickel sheet mounting device for a bipolar plate flow channel groove in alkaline electrolyzed water hydrogen production, including a processing table 1. A conveying mechanism 4 is arranged inside the processing table 1. The conveying mechanism 4 includes a first conveying seat 401, a second conveying seat 402 and a bipolar plate main body 403. The first conveying seat 401 is movably connected inside the processing table 1, the second conveying seat 402 is movably connected inside the processing table 1, and the bipolar plate main body 403 is arranged inside the first conveying seat 401 and the second conveying seat 402.

[0035] With the above scheme: After clamping the bipolar plate main body 403 between the first conveying seat 401 and the second conveying seat 402, start the conveying rollers on the first conveying seat 401 and the second conveying seat 402 to move the bipolar plate main body 403 to the mounting position.

[0036] As Figures 1 to 10 shown in the figure, a mounting mechanism 5 is installed inside the processing table 1, a feeding mechanism 8 is installed inside the processing table 1, a cleaning mechanism 9 is arranged inside the processing table 1, support feet 2 are installed at the bottom end of the processing table 1, a cabinet door 3 is rotatably connected inside the processing table 1, a vibration motor 6 is fixed at the bottom end inside the processing table 1, a feeding box 7 is fixed at the top end of the vibration motor 6, there are four groups of support feet 2 symmetrically distributed about the central axis of the processing table 1, and there are two groups of cabinet doors 3 symmetrically distributed about the central axis of the processing table 1.

[0037] With the above scheme: By starting the vibration motor 6, the feeding box 7 can be vibrated, and then the nickel sheet patches 805 inside the feeding box 7 can be vibrated, so that when the electromagnetic box 804 moves here, it can suck the nickel sheet patches 805 that are vibrated and lifted, thus completing the feeding.

[0038] As Figures 1 to 10 shown in the figure, the mounting mechanism 5 includes a first servo motor 501, a first screw rod 502 and a support seat 503. The first servo motor 501 is fixed at the top end of the processing table 1, the output end of the first servo motor 501 is fixed with the first screw rod 502, the outer thread of the first screw rod 502 is threadedly connected with the support seat 503, the top end of the support seat 503 is fixed with a second servo motor 504, and the output end of the second servo motor 504 is fixed with a second screw rod 505. The outer thread of the second screw rod 505 is threadedly connected with a fitting assembly 506.

[0039] With the above scheme: By starting the first servo motor 501, the support seat 503 and the second servo motor 504 can be driven to move longitudinally. By starting the second servo motor 504, the fitting assembly 506 can be driven to move horizontally, so as to quickly adjust the position of the fitting assembly 506, so that after sucking the nickel sheet patches 805, it can move above the bipolar plate main body 403, and then start the cylinder inside the liquid storage box 806 to move the nickel sheet patches 805 down to contact the mounting position of the bipolar plate main body 403 and then heat to complete the mounting.

[0040] As Figures 1 to 10 shown, the feeding mechanism 8 includes a conveying cylinder 801, a third servo motor 802 and an engaged conveyor belt 803. The conveying cylinder 801 is movably connected inside the processing table 1. A third servo motor 802 is fixed to the outside of the conveying cylinder 801. An engaged conveyor belt 803 is sleeved on the outside of the conveying cylinder 801. An electromagnetic box 804 is fixed to the outside of the engaged conveyor belt 803. There are four groups of conveying cylinders 801, and the conveying cylinders 801 are symmetrically distributed about the central axis of the processing table 1. The third servo motor 802 is fixed at one end inside the processing table 1. There are several groups of electromagnetic boxes 804, and the electromagnetic boxes 804 are arranged at equal intervals.

[0041] As Figures 1 to 10 shown, a nickel patch 805 is arranged inside the electromagnetic box 804. A liquid storage box 806 is fixed inside the processing table 1. A delivery pump 807 is fixed to the outside of the liquid storage box 806. A delivery head 808 is installed at one end of the liquid storage box 806. Holes are formed on the surface of the engaged conveyor belt 803, and holes are formed at the bottom end of the electromagnetic box 804. The hole diameters of the engaged conveyor belt 803 and the electromagnetic box 804 are the same. The input end of the delivery pump 807 communicates with the liquid storage box 806, and the output end of the delivery pump 807 communicates with the delivery head 808.

[0042] As Figures 1 to 10 shown, it further includes a cleaning cylinder 809. A cleaning sleeve 810 is wrapped around the outer circumference of the cleaning cylinder 809. The cleaning sleeve 810 contacts the inner peripheral wall of the engaged conveyor belt 803. The cleaning cylinder 809 is arranged between adjacent conveying cylinders 801. The hole of the electromagnetic box 804 is a round hole. Defining the hole diameter of the electromagnetic box 804 as d and the diameter of the nickel patch 805 as D, then it satisfies: 0.5 < d / D < 0.8.

[0043] Adopting the above solution: By starting the third servo motor 802, the meshing conveyor belt 803 is driven to move. Then, the nickel chip patch 805 vibrated by the vibration motor 6 inside the feeding box 7 is sucked up by the magnetic force of the electromagnetic box 804 and conveyed upward, and is mounted after reaching the top. Since the flux is sprayed by the delivery pump 807, the flux will inevitably be sprayed onto the inner peripheral wall of the meshing conveyor belt 803. By setting the cleaning cylinder 809, the cleaning sleeve 810 of the cleaning cylinder 809 is brought into contact with the inner peripheral wall of the meshing conveyor belt 803. When the meshing conveyor belt 803 is operating, the residual flux will be cleaned in time, avoiding the flux from polluting the working environment and equipment. After the cleaning sleeve 810 is used for a period of time, it is also convenient to replace, ensuring the cleaning effect of the flux. By setting the ratio relationship between the hole of the electromagnetic box 804 and the diameter of the nickel chip patch 805, that is, the position where the flux is sprayed on the nickel chip patch 805 is limited. If too little flux is sprayed, the welding firmness of the nickel chip patch 805 will be affected. If too much flux is sprayed, on the one hand, the flux is wasted, and secondly, the excess flux needs to be cleaned additionally, increasing the cleaning process and cost. Moreover, the residual flux may pollute the working environment and equipment.

[0044] As Figures 1 to 10 shown, the cleaning mechanism 9 includes a connecting block 901, a cleaning rod 902 and a mounting seat 903. The connecting block 901 is movably connected inside the processing table 1. A cleaning rod 902 is rotatably connected inside the connecting block 901. A mounting seat 903 is fixed to the outside of the cleaning rod 902. A first limiting rod 904 is fixed to the outside of the mounting seat 903. A first limiting disk 905 is fixed to the outside of the first limiting rod 904. A second limiting disk 906 is sleeved on the outside of the first limiting rod 904. The connecting block 901 is slidably connected to the processing table 1. A plurality of groups of cleaning hairs are provided on the outer wall of the cleaning rod 902. The diameter of the first limiting disk 905 is smaller than the diameter of the second limiting disk 906. The second limiting disk 906 is slidably connected to the first limiting rod 904.

[0045] As Figures 1 to 10 shown, a second limiting rod 907 is movably connected inside the processing table 1. A return spring 908 is sleeved on the outside of the second limiting rod 907. A limiting block 909 is fixed to the outside of the second limiting rod 907. The outer wall of the second limiting rod 907 is close to the inner wall of the processing table 1. The second limiting rod 907 is slidably connected to the processing table 1. The return spring 908 is used to squeeze the second limiting rod 907 and keep it in a tendency to move outward.

[0046] Adopting the above solution: By pressing the connecting block 901, when the second limiting disc 906 contacts the limiting block 909, the limiting block 909 and the second limiting rod 907 are squeezed. After passing through the limiting block 909, the return spring 908 resets the limiting block 909, causing the limiting block 909 to lift the second limiting disc 906 to contact the first limiting disc 905. At this time, pulling the connecting block 901 can take out the whole cleaning rod 902 for replacement. During installation, press the connecting block 901. When the first limiting disc 905 contacts the limiting block 909, the limiting block 909 is squeezed. The limiting block 909 and the second limiting rod 907 contract, and after the first limiting disc 905 passes, the return spring 908 resets the limiting block 909 and the second limiting rod 907, thereby limiting the cleaning rod 902. At this time, the cleaning rod 902 can rotate.

[0047] The working principle and usage process of the present invention: After clamping the bipolar plate body 403 between the first conveying seat 401 and the second conveying seat 402, start the conveying rollers on the first conveying seat 401 and the second conveying seat 402 to move the bipolar plate body 403 to the mounting position. And start the third servo motor 802 to drive the meshing conveyor belt 803 to move. Then, the nickel patch 805 vibrated by the vibration motor 6 inside the feeding box 7 is sucked up by the magnetic force of the electromagnetic box 804 and conveyed upward. After reaching the top, it is mounted. When conveying the nickel patch 805, start the transfer pump 807 to spray the flux inside the liquid storage box 806 through the transfer head 808, the holes of the meshing conveyor belt 803 and the electromagnetic box 804 onto the welding surface of the nickel patch 805, so that when the fitting assembly 506 sucks up the nickel patch 805 for mounting, it can be more firm. And when the nickel patch 805 moves and is conveyed through the meshing conveyor belt 803, after the nickel patch 805 contacts the cleaning rod 902, the cleaning rod 902 cleans the dust and impurities adhered to the surface of the nickel patch 805, avoiding the phenomenon that the fitting assembly 506 detaches after sucking up the nickel patch 805. By pressing the connecting block 901, when the second limiting disc 906 contacts the limiting block 909, the limiting block 909 and the second limiting rod 907 are squeezed. After passing through the limiting block 909, the return spring 908 resets the limiting block 909, causing the limiting block 909 to lift the second limiting disc 906 to contact the first limiting disc 905. At this time, pulling the connecting block 901 can take out the whole cleaning rod 902 for replacement. During installation, press the connecting block 901. When the first limiting disc 905 contacts the limiting block 909, the limiting block 909 is squeezed. The limiting block 909 and the second limiting rod 907 contract, and after the first limiting disc 905 passes, the return spring 908 resets the limiting block 909 and the second limiting rod 907, thereby limiting the cleaning rod 902. At this time, the cleaning rod 902 can rotate.
