Description

Technical Field

[0001] The invention belongs to the technical field of electrolytic cell assembly, and in particular relates to an electrolytic cell automatic hydraulic assembly device and method. Background Art

[0002] Electrolyzer assembly is the process of stacking the individual components of the electrolyzer layer by layer according to the design drawings and process requirements, ensuring that the electrodes and diaphragms between each battery are aligned, and then applying uniform pressure through pressing equipment to form a whole. During the pressing process, it is necessary to ensure that the various components do not shift to avoid uneven stress that affects the stability of the electrolyzer.

[0003] A Chinese patent application document with application publication number CN118186433A discloses an anti-skid device for an electrolytic cell, comprising: an electrolytic cell and an anti-skid device, wherein the electrolytic cell comprises a lower end plate, a lower insulating plate, a lower current collecting plate, a bipolar plate, an upper current collecting plate, an upper insulating plate and an upper end plate; the anti-skid device comprises a base, a support column, an outer positioning plate and an inner movable rod, wherein the support column is arranged on the base, and the outer positioning plate is arranged on the support column; the electrolytic cell is arranged on the base, and the inner movable rod passes through the electrolytic cell and is fixed on the base. The invention mainly utilizes local fixation during the assembly process to limit the relative sliding between the plates, expands the restriction on the number of bipolar plates in the electrolytic cell, and thus plays a role in avoiding deformation of the electrolytic cell caused by sliding of the plates in a high-power electrolytic cell.

[0004] When assembling a high-power electrolyzer, the number of bipolar plates may be as high as hundreds. The electrolyzer is usually equipped with clamps to fix and compress the various components of the electrolyzer. Therefore, the existing electrolyzer assembly equipment uses external positioning plates to provide side support for the electrolyzer during press-fitting. When the external positioning plate is at the clamp, it will be blocked by the clamp, making it impossible for the external positioning plate to provide effective support for the bipolar plate, causing the bipolar plate at this location to shift sideways during press-fitting, thereby generating uneven stress and affecting the stability and sealing of the electrolyzer. Summary of the invention

[0005] The object of the present invention is to provide an electrolytic cell automated hydraulic assembly device and method, aiming to solve the problem in the prior art that the outer positioning plate of the electrolytic cell assembly device will be blocked by the clamp when it is at the clamp, so that the outer positioning plate cannot provide effective support for the bipolar plate, causing the bipolar plate at this location to shift sideways during press assembly.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an electrolytic cell automated hydraulic assembly device comprises a base, a press-fitting device and a positioning and supporting device located on the base, a chamber is provided in the base, and first slide grooves extending in the left and right directions are provided on both sides of the top of the base, the positioning and supporting device comprises a positioning mechanism, a supporting mechanism and a lifting mechanism located in the chamber, and the lifting mechanism drives the positioning mechanism and the supporting mechanism to lift and lower.

[0007] The positioning mechanism comprises a vertically arranged positioning rod, the top of which slides through the base to position the electrolytic cell accessories when the electrolytic cell is assembled.

[0008] The supporting mechanism includes a supporting plate symmetrically arranged on the left and right, a supporting block located on the middle side of the supporting plate close to the base, a connecting rod and a telescopic member driving the supporting plate to move left and right. The top end of the supporting plate slides through a first sliding groove. There are multiple supporting blocks and they are stacked in a vertical direction. One end of the connecting rod is fixedly connected to the supporting block, and the other end of the connecting rod is slidably sleeved in the supporting plate. An elastic member sleeved on the connecting rod is provided between the supporting plate and the supporting block.

[0009] The lifting mechanism comprises a lifting plate and a driving assembly for driving the lifting plate to lift and lower. The positioning rod and the supporting plate are both installed on the lifting plate.

[0010] The effect is that it can support the side walls of the electrolytic cell when the electrolytic cell is pressed, and it can also support the bipolar plates at the clamps, avoiding the bipolar plates at the clamps from not being able to obtain effective support, causing the bipolar plates at this location to shift sideways during press-fitting, thereby generating uneven stress and affecting the stability and sealing of the electrolytic cell.

[0011] An air cavity is provided inside the support plate, and a plurality of support grooves are provided on one side of the air cavity close to the support block. The plurality of support grooves correspond to the plurality of support blocks respectively, and a piston block is slidably sleeved in the support groove. One end of the connecting rod extends into the support groove and is fixedly connected to the piston block.

[0012] The top and bottom of the support block are provided with storage grooves, and the side of the storage groove away from the support plate passes through the support block. A movable plate is slidably sleeved up and down in the storage groove, and a spring is provided between the movable plate and the storage groove. The side of the movable plate close to the support plate is an inclined surface, and the end of the inclined surface close to the spring is inclined toward the direction close to the support plate.

[0013] The effect is that, by providing the receiving groove and the movable plate, when the clamp is just between the two support blocks, the movable plate can support the bipolar plate at the clamp, thereby avoiding the bipolar plate at the clamp not being able to obtain effective support, causing the bipolar plate at this location to shift sideways during press installation.

[0014] There are four support plates and four first slide grooves, which are symmetrically arranged on the front and rear sides of the top ends of the base. There are four telescopic members, which correspond to the four support plates respectively. The front and rear sides of the outer walls of the support plates are provided with connecting slide grooves extending up and down. A connecting block is provided at the telescopic end of the telescopic member, which is slidably connected to the support plate through the connecting slide groove. A connecting part is provided at the bottom of the support plate, and a card slot is provided on the connecting part for slidingly sleeved with the lifting plate in the left and right directions.

[0015] The positioning mechanism also includes a slider installed on the lifting plate and a guide sleeve installed on the top of the base. The positioning rod is slidably sleeved in the guide sleeve. The position of the electrolytic cell accessories is positioned when the electrolytic cell is assembled. The positioning rod includes a movable rod, a fixed rod and a supporting telescopic rod. There are four movable rods and they are evenly distributed along the circumference of the fixed rod. A mounting groove is opened on the top of the slider. The bottom end of the fixed rod is fixedly connected to the middle of the mounting groove. The bottom end of the movable rod extends into the mounting groove and is slidably connected thereto. There are multiple supporting telescopic rods and they are evenly distributed on the four side walls of the fixed rod in the vertical direction. The telescopic end of the supporting telescopic rod is fixedly connected to the movable rod.

[0016] The effect is that the diameter of the positioning rod can be adjusted so that the positioning rod just matches the size of the slot or hole selected for positioning on the electrolytic cell part, so that the present invention can be applied to the assembly of electrolytic cells of various sizes.

[0017] A second slide groove pointing to the center of the top of the base is opened on the top of the base, and an installation slide groove corresponding to the second slide groove is opened on the top of the lifting plate. The number of positioning rods, guide sleeves, second slide grooves and installation slide grooves is four and they are evenly distributed along the circumference of the base. The four guide sleeves are respectively slidably connected in the four second slide grooves, and the four sliders are respectively slidably connected in the four installation slide grooves.

[0018] The effect is that the positioning rod is pushed to slide along the installation slide groove, thereby adjusting the spacing between the four positioning rods so that the four positioning rods just correspond to the positions of the slots or holes selected for positioning on the electrolytic cell parts to be assembled, so that the positioning rods can accurately position the electrolytic cell.

[0019] The driving assembly includes a motor, a limit column with an axis extending in the up and down directions, and a lead screw. The lead screw is rotatably installed in the middle of the bottom end of the chamber, the motor is located at the top end of the chamber, the output shaft of the motor is transmission-connected to the top of the lead screw, the lifting plate is threadedly connected to the outer wall of the lead screw, the limit column is fixedly installed at the bottom end of the chamber, and the lifting plate is slidably sleeved on the limit column.

[0020] The effect is that the lifting mechanism drives the positioning mechanism and the supporting mechanism to rise, so that the height of the positioning rod can be gradually increased as the assembly proceeds, avoiding the positioning rod being too high at the beginning, which makes it difficult to assemble the electrolytic cell parts in the initial stage.

[0021] The pressing device includes a top plate, a hydraulic mechanism connecting part and a pressing plate. The support rod is located between the top plate and the base. The number of support rods is and they are respectively located at the four corners of the top plate. The hydraulic mechanism is installed in the middle of the top of the top plate. The pressing plate is located between the top plate and the base. The telescopic end of the hydraulic mechanism slides through the top plate and is connected to the pressing plate through the connecting part.

[0022] The present invention also includes an automated hydraulic assembly method for an electrolytic cell, the specific method of which is as follows:

[0023] First, the lifting mechanism is controlled to drive the positioning mechanism and the supporting mechanism to rise, and then the accessories of the electrolytic cell are hoisted to the top of the base by the manipulator, and the accessories of the electrolytic cell are assembled one by one through the cooperation of the positioning rod. As the number of electrolytic cell accessories gradually increases, the lifting mechanism drives the positioning mechanism and the supporting mechanism to gradually rise, so that the top of the positioning rod is always located above the electrolytic cell. After the hoisting is completed, the telescopic end of the telescopic part is pushed out and pushes the support plate toward the hoisted electrolytic cell, so that the support block is in conflict with the side wall of the electrolytic cell, and finally the pressing device is started to press the assembled electrolytic cells.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] It can support the side wall of the electrolytic cell when the electrolytic cell is pressed, and can also support the bipolar plate at the clamp, avoiding the bipolar plate at the clamp not being able to obtain effective support, causing the bipolar plate at this location to shift sideways during press-fitting, thereby generating uneven stress and affecting the stability and sealing of the electrolytic cell.

[0058] The implementation principle of the embodiment of the present invention is:

[0059] When assembling the electrolytic cell, firstly start the motor of the lifting mechanism 33 to drive the lead screw 334 to rotate, so that the lifting plate 331 drives the positioning mechanism 31 and the supporting mechanism 32 to rise to a certain height, and then push the positioning rod to slide along the installation slide groove 332, so as to adjust the spacing between the four positioning rods, so that the four positioning rods just correspond to the positions of the slots or holes selected for positioning on the electrolytic cell parts to be assembled, and start the supporting telescopic rod 315 to extend its telescopic section, so as to drive the movable rod 311 to slide along the installation slot 3131 and away from the fixed rod 312. When the telescopic section is retracted, it drives the movable rod 311 to slide along the installation slot 3131 and away from the fixed rod 312. 11 slides along the installation groove 3131 and approaches the fixing rod 312, thereby adjusting the diameter of the positioning rod so that the positioning rod just matches the size of the groove or hole selected for positioning on the electrolytic cell parts, and then the electrolytic cell parts are installed on the positioning rod in sequence by the manipulator. When the height of the electrolytic cell is flush with the top of the positioning rod, the motor of the lifting mechanism 33 is started again, so that the lifting mechanism 33 drives the positioning mechanism 31 and the supporting mechanism 32 to rise, so that the height of the positioning rod can be gradually increased as the assembly proceeds, avoiding the situation where the height of the positioning rod is too high at the beginning, making it difficult to assemble the electrolytic cell parts at the beginning of lifting.

[0060] After the electrolytic cell is hoisted, the telescopic member 328 is started to push out its telescopic end and drive the support plate 321 to move toward the electrolytic cell after hoisting. When the support block 324 contacts the side wall of the electrolytic cell (such as Fig. 9As shown in the figure, the hoop 42 on the side wall of the electrolytic cell pushes the support block 324 in contact with it toward the support plate 321, so that the elastic member 326 between the support block 324 and the support plate 321 is compressed, and at the same time, the piston block 327 is driven to slide toward the air cavity 3211 through the connecting rod 325. At this time, the pressure in the air cavity 3211 increases, and drives the remaining piston blocks 327 to slide toward the support block 324. At the same time, the support block 324 is pressed against the side wall of the bipolar plate 41 of the electrolytic cell through the connecting rod 325. When the hoop 42 is just between the two support blocks 324, both support blocks 324 will be pushed toward the support plate 321. At this time, the support block 324 pushed toward the support plate 321 is opposite to the support block 324 The movable plates 3242 on the remaining adjacent support blocks 324 are pressed out of the receiving grooves 3241 by the springs and come into contact with the upper and lower surfaces of the clamp 42, thereby pressing the bipolar plates 41 corresponding to the support blocks 324 that are pushed toward the support plates 321, so that the bipolar plates 41 adjacent to the clamp 42 can also be pressed by the support blocks 324, thereby supporting the side walls of the electrolytic cell when the electrolytic cell is press-assembled, and also supporting the bipolar plates 41 at the clamp 42, thereby avoiding the bipolar plates 41 at the clamp 42 from being unable to obtain effective support, causing the bipolar plates 41 at that location to shift sideways during press-assembly, thereby generating uneven stress and affecting the stability and sealing of the electrolytic cell.

[0061] refer to Figure 1-Figure 10 As shown, the present invention also includes an automated hydraulic assembly method for an electrolytic cell, and the specific method is as follows:

[0062] First, the lifting mechanism 33 is controlled to drive the positioning mechanism 31 and the supporting mechanism 32 to rise, and then the accessories of the electrolytic cell are hoisted to the top of the base 1 by the manipulator, and the accessories of the electrolytic cell are assembled together one by one through the cooperation of the positioning rod. As the number of accessories of the electrolytic cell gradually increases, the lifting mechanism 33 drives the positioning mechanism 31 and the supporting mechanism 32 to gradually rise, so that the top of the positioning rod is always located above the electrolytic cell. After the hoisting is completed, the telescopic end of the telescopic member 328 is pushed out and pushes the support plate 321 toward the hoisted electrolytic cell, so that the support block 324 is in conflict with the side wall of the electrolytic cell, and finally the pressing device 2 is started to press the assembled electrolytic cells.

[0063] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
