[0037] The following describes the implementation of the present invention through specific embodiments. People skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.
[0038] The present invention provides a clamping device for electrode sheet production, such as Figures 1 to 5 shown.
[0039] In an exemplary embodiment, a clamping device for producing an electrode sheet includes:
[0040] The bearing seat 3 is provided with a guide groove 10, and at least two clamping seats 11 are provided in the guide groove 10 for overlapping. The clamping seats 11 are provided with a support surface 1101 for supporting the foam nickel sheet 2, and the space between the clamping seats 11 is used for clamping the foam nickel sheet 2;
[0041] A first lifting mechanism, the output end of which is connected to the guide groove 10 and is used to drive the support surface 1101 on the vacant clamping seat 11 to be flush with the output of the conveying mechanism 1 for conveying the foam nickel sheet 2;
[0042] A magnetic attraction mechanism is installed in the supporting seat 3 and is used to guide the nickel foam sheet 2 to a preset position on the clamping seat 11;
[0043] When the nickel foam sheet 2 reaches the preset position in the clamping seat 11 , another empty clamping seat 11 is overlapped with the clamping seat 11 on the support surface 1101 with the nickel foam sheet 2 placed thereon to press the nickel foam sheet 2 .
[0044] During use, the first lifting mechanism is used to align the empty clamping seat 11 with the output of the conveying mechanism 1, so that the nickel foam sheet 2 driven by the conveying mechanism 1 is conveyed to the empty clamping seat 11, and then the nickel foam sheet 2 is adsorbed by the magnetic mechanism so that the nickel foam sheet 2 is moved to the corresponding position in the clamping seat 11 under the magnetic attraction of the magnetic mechanism, and then another empty clamping seat 11 is overlapped on the clamping seat 11 where the nickel foam sheet 2 is placed to compress the nickel foam sheet 2 and fix the nickel foam sheet 2. After placing the nickel foam sheet 2 in each empty clamping seat 11, each clamping seat 11 is fixed, and then the clamping seat 11 can be clamped as a whole to clamp multiple nickel foam sheets 2 to the next production process.
[0045] Exemplarily, the first lifting mechanism includes a fixed plate 8 and a plurality of cylinders 9 mounted on the fixed plate 8 , and output ends of the cylinders 9 are connected to the guide grooves 10 .
[0046] In an exemplary embodiment, the clamping device for electrode sheet production further includes a second lifting mechanism, and the second lifting mechanism includes:
[0047] Mounting Block 4,
[0048] The rotary drive mechanism 5 is mounted on the mounting base 4;
[0049] The first threaded column 6 is connected to the output end of the rotary drive mechanism 5 and is driven to rotate by the rotary drive mechanism 5;
[0050] The first threaded column 6 is used for threaded connection with the clamping seat 11 to fix the clamping seat 11 .
[0051] Exemplarily, the rotation drive mechanism 5 is a motor.
[0052] Exemplarily, four motors are provided on the mounting seat 4 , and the output ends of the four motors are respectively connected to the first threaded columns 6 . The clamping seat 11 is provided with threaded holes for connecting the four threaded columns, and the four threaded holes are distributed on both sides of the support surface 1101 .
[0053] Exemplarily, the second lifting mechanism is arranged directly above the supporting seat 3, and the first threaded column 6 is arranged toward the supporting seat 3 below the second lifting mechanism; the vacant clamping seat 11 is threadedly connected to the first threaded column 6 and overlapped on the first threaded column 6, suspended directly above the guide groove 10, with the bottom end of the first threaded column 6 close to the supporting seat 3 in the guide groove 10. After the nickel foam sheet 2 in the clamping seat 11 in the guide groove 10 is aligned, the rotary drive mechanism 5 rotates synchronously in the same direction, so that the vacant clamping seat 11 at the bottom end of the first threaded column 6 moves down along the first threaded column 6 to the clamping seat 11 in the guide groove 10 to press the nickel foam sheet 2. The first lifting mechanism is then controlled to move so that the support surface 1101 of the clamping seat 11 newly installed in the guide groove 10 is aligned with the output of the conveying mechanism 1, and the fixation of another nickel foam sheet 2 is continued.
[0054] It should be noted that when the clamping seat 11 is installed in the bearing seat 3, it can be achieved through the second lifting mechanism or manually by an operator.
[0055] For example, after the nickel foam sheets 2 to be clamped are all loaded into the corresponding clamping seats 11, the first lifting mechanism is controlled to move so that the guide groove 10 and the clamping seat 11 in the guide groove 10 rise, and at the same time, the rotation drive mechanism 5 in the second lifting mechanism is controlled to move so that the first threaded column 6 and the clamping seat 11 in the guide groove 10 are threadedly connected to achieve fixation between each clamping seat 11.
[0056] In an exemplary embodiment, the magnetic mechanism includes a first magnetic component 7, a second magnetic component 12, and a transverse movement component 13 for driving the second magnetic component 12 to move from the output end of the conveying mechanism 1 to the clamping seat 11. The first magnetic component 7 is arranged on the side of the supporting seat 3 away from the conveying mechanism 1.
[0057] In this embodiment, the second magnetic assembly 12 is used to attract the nickel foam sheet 2 in the clamping seat 11 toward one side of the clamping seat 11, and the movement of the second magnetic assembly 12 drives the nickel foam sheet 2 to move. The first magnetic assembly 7 is configured to cause the nickel foam sheet 2 in the clamping seat 11 to move toward the end of the clamping seat 11 away from the conveying mechanism 1, thereby achieving compression of the nickel foam sheet 2 in the supporting seat 3.
[0058] For example, the traverse assembly 13 includes a motor, a second threaded post, and a slider. The second magnetic assembly 12 is installed in the slider. By controlling the rotation of the motor, the second threaded post rotates, thereby achieving the movement of the slider. The movement of the slider guides the movement of the nickel foam sheet 2.
[0059] In an exemplary embodiment, the first magnetic attraction component 7 and the second magnetic attraction component 12 both include electromagnets.
[0060] It should be noted that in addition to electromagnets, the first magnetic attraction component 7 and the second magnetic attraction component 12 in the present application can also be made of permanent magnets. However, in order to achieve control of the magnetic attraction time, etc., the first magnetic attraction component 7 and the second magnetic attraction component 12 in this solution both include electromagnets. The magnetic attraction time of the first magnetic attraction component 7 and the second magnetic attraction component 12 and the magnetic attraction direction of the second magnetic attraction component 12 can be controlled by controlling the power on and off of the electromagnets.
[0061] It should also be noted that, since the nickel foam sheet 2 is porous, it cannot be stably adsorbed by negative pressure adsorption or the like, and therefore the nickel foam sheet 2 is adsorbed by magnetic attraction.
[0062] Exemplarily, the second magnetic component 12 is first moved to the end of the clamping seat 11 close to the conveying mechanism 1 by the transverse movement component 13, and then the electromagnet in the second magnetic component 12 is controlled to be energized, so that the foam nickel sheet 2 moves toward the side where the second magnetic component 12 is located, and then the second magnetic component 12 is controlled to move toward the end away from the conveying mechanism 1, so that the end of the foam nickel sheet 2 abuts against the guide groove 10. When the foam nickel sheet 2 is close to the end of the clamping seat 11 away from the conveying mechanism 1, the electromagnet in the first magnetic component 7 is controlled to be energized to increase the adsorption effect on the foam nickel sheet 2. When a piece of foam nickel sheet 2 reaches the corresponding position, the second magnetic component 12 stops working, and the second magnetic component 12 is moved to the end of the clamping seat 11 close to the conveying mechanism 1, so as to facilitate the adsorption and guidance of the next foam nickel sheet 2.
[0063] In an exemplary embodiment, the clamping seat 11 has a first surface and a second surface in the thickness direction, a clamping groove is provided on the first surface, and connecting platforms 1102 are provided on both sides of the clamping groove for the first threaded column 6 to pass through, the supporting surface 1101 is located in the clamping groove, and a boss 1103 is protruded on the second surface for pressing the foam nickel sheet 2.
[0064] In this embodiment, the nickel foam sheet 2 and the clamping seat 11 can be directly immersed in the electrodeposition solution for catalyst deposition. However, considering that catalyst deposition needs to be achieved on the surface of the nickel foam, the structure of the boss 1103 needs to be specially designed. In this solution, the boss 1103 is positioned at the three side edges of the clamping groove away from the conveyor mechanism 1 to ensure stable clamping of the nickel foam sheet 2 while reducing the coverage of the boss 1103 on the nickel foam sheet 2.
[0065] It should also be noted that the nickel foam sheet 2 and the clamping seat 11 can also be directly immersed in the electroplating solution to increase the connection stability between the clamping seat 11. In this case, a through hole can be opened on the side wall of the guide groove 10 to allow the electroplating solution to enter and exit.
[0066] For example, in order to further reduce the coverage area of the boss 1103 on the nickel foam sheet 2 , a flow channel may be provided on the side of the boss 1103 in contact with the nickel foam sheet 2 to facilitate entry of the electrodeposition solution.
[0067] For example, in order to further reduce the coverage of the boss 1103 on the nickel foam sheet 2, in addition to setting a flow channel on the side where the boss 1103 contacts the nickel foam sheet 2, a pin for inserting the nickel foam sheet 2 can also be set on the side where the boss 1130 contacts the nickel foam sheet 2.
[0068] In an exemplary embodiment, a plurality of first through holes 1104 are defined on the support surface 1101 , and the first through holes 1104 penetrate the support surface 1101 and the second surface.
[0069] It should be noted that the first through hole 1104 is provided to facilitate the entry of the electroplating liquid and the like into the clamping seats 11 .
[0070] In an exemplary embodiment, a second through hole 1105 is defined at one end of the connecting platform 1102 close to the supporting surface 1101 .
[0071] It should be noted that the second through hole 1105 is provided to facilitate the entry of the electroplating liquid and the like into the clamping seats 11 .
[0072] In an exemplary embodiment, the first threaded column 6 is detachably connected to the rotary drive mechanism 5 , and the output end of the first lifting mechanism is detachably connected to the guide groove 10 . The first threaded column 6 is also used to pass through the clamping seat 11 and then be threadedly connected to the guide groove 10 .
[0073] In this embodiment, the first threaded column 6 and the rotary drive mechanism 5 can be detachably connected by means of snap-fitting or the like, and the output end of the first lifting mechanism and the guide groove 10 can be detachably connected by means of snap-fitting or the like, and the clamping seat 11 and the like can be separated from the mounting seat 4 and the rotary drive mechanism 5 and the like, so as to facilitate the clamping of the clamping seat 11 and the like fixed by the first threaded column 6 into the electroplating liquid.
[0074] It should be noted that the first threaded column 6 is not only threadedly connected to the clamping seat 11 , but also threadedly connected to the guide groove 10 , so as to increase the connection stability between the clamping seat 11 and further increase the clamping stability of the nickel foam sheet 2 .
[0075] In an exemplary embodiment, the clamping device for electrode sheet production further includes a third lifting mechanism, and an output end of the third lifting mechanism is fixed to the mounting seat 4 .
[0076] It should be noted that after being clamped, the nickel foam sheet 2 can be placed in the electrodeposition solution in a horizontal position, or it can be switched to a vertical position by a flip mechanism according to on-site requirements. When it is necessary to place the nickel foam sheet 2 in the electrodeposition solution horizontally, the second lifting mechanism and the clamping base 11 can be moved upward by the third lifting mechanism, and the clamping base 11 can be moved into the electrodeposition solution by a separate transverse movement mechanism.
[0077] In accordance with the above-mentioned clamping device for electrode sheet production, a clamping method for electrode sheet production is also provided, the method comprising:
[0078] Step S100, controlling the first lifting mechanism to move so that the empty clamping seat 11 is flush with the output of the conveying mechanism 1, and conveying the nickel foam sheet 2 to the supporting surface 1101 of the empty clamping seat 11;
[0079] Step S200, controlling the magnetic attraction mechanism to attract the nickel foam sheet 2 to a preset position in the clamping seat 11;
[0080] Step S300, installing another empty clamping seat 11 in the guide groove 10, so that the empty clamping seat 11 overlaps with the clamping seat 11 containing the nickel foam sheet 2, and pressing the nickel foam sheet 2 in the clamping seat 11;
[0081] Step S400 : After the nickel foam sheet 2 is clamped in the clamping seat 11 , the clamping seats 11 are fixed to each other and the clamping seats 11 are clamped.
[0082] In this solution, the nickel foam sheet 2 in the clamping seat 11 is shaped by magnetic attraction, so that the nickel foam sheet 2 is regularized to the required position in the clamping seat 11, so that the nickel foam can be stably fixed when another controlled clamping seat 11 is installed.
[0083] Since the nickel foam is compressed by the two clamping seats 11 , when the two clamping seats 11 are overlapped, the compression of the nickel foam can be achieved by the gravity of the upper clamping seat 11 itself.
[0084] Since the nickel foam sheet 2 is porous, it cannot be stably fixed by negative pressure adsorption or the like, so it is fixed by clamping.
[0085] The clamping device for electrode sheet production provided in the above embodiment and the clamping method for electrode sheet production provided in the above embodiment belong to the same concept. The clamping method for electrode sheet production is described in detail in the embodiment of the clamping device for electrode sheet production and will not be repeated here.
[0086] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
