Description

Technical Field

[0001] The invention belongs to the technical field of electrode spraying, in particular to an electrode spraying device. Background Art

[0002] Alkaline electrolyzer is a commonly used device for producing hydrogen by electrolysis of water, and one of its core components is the electrode. The main function of the electrode of the alkaline electrolyzer is to catalyze the decomposition of water molecules during the electrolysis process to produce hydrogen and oxygen. The electrode of the alkaline electrolyzer is usually made of nickel mesh. During the processing of the nickel mesh, an oxide coating or a catalyst coating needs to be sprayed on the nickel mesh through a spraying device to improve the efficiency of hydrogen production by electrolysis of water.

[0003] The patent with publication number CN117463519A discloses an automatic spraying device for a mesh electrode, including a base, a turntable, a mounting seat, and a mounting rod. The turntable is rotatably mounted on the base, and four groups of mounting seats are equiangularly mounted on the turntable. The mounting seat is provided with a mounting rod for limiting the mesh electrode body. The scheme places the mesh electrode body on the mounting seat and applies pressing force to limit the mesh electrode body on the mounting seat, thereby preventing the mesh electrode body from being blown over by airflow or even falling off the workbench. By driving the extrusion rod close to the end of the protrusion, the protrusion will be squeezed toward the outside of the first connecting groove until the protrusion is completely disengaged from the first connecting groove, and at this time, the fixed block will enter the fixed groove as the connecting rod moves, thereby releasing the fixation of the mounting plate, thereby facilitating the staff to replace the mesh electrode body.

[0004] In the above scheme, only one side of the mesh electrode body can be sprayed at a time. Single-sided spraying will cause the oxide or catalyst to be unevenly distributed on the entire electrode surface, thereby failing to ensure the performance consistency of the electrode. If both sides are sprayed, the mesh electrode body needs to be turned over. Before turning over, the previously sprayed surface needs to be dried, which will waste a lot of time and reduce the efficiency of electrode spraying. For this reason, the present invention provides an electrode spraying device. Summary of the invention

[0007] Preferably, the end of the drive shaft is covered with a rubber sleeve, and the rubber sleeve is tightly attached to a set of plates; By setting the rubber sleeve, direct contact between the drive shaft and the plate body and the rotating seat is avoided, thereby reducing wear between the drive shaft and the plate body and the rotating seat, and increasing the service life of the drive shaft, the plate body and the rotating seat.

[0008] Preferably, the chain plate assembly also includes a movable shaft, the movable shaft is plugged into the placement rod, a spring sleeved on the placement rod, four groups of fixing parts distributed at equal angles around the end of the movable shaft, four groups of avoidance holes are opened at equal angles on the placement rod, the four groups of fixing parts are respectively hinged to the four groups of avoidance holes, four groups of avoidance grooves are opened at equal angles on the end of the movable shaft, a rectangular groove is opened on the fixing part, one end of the fixing part is located in the avoidance groove, pins are arranged in the four groups of avoidance grooves, the pins are located in the rectangular grooves, a roller is rotatably installed at the other end of the movable shaft, a guide ring is arranged in the bracket, the two ends of the guide ring are respectively sleeved on the two groups of transmission shafts, the roller is rotatably connected to the inner ring of the guide ring, and the inner ring of the guide ring is composed of a first ring surface, a second ring surface, and an inclined surface; The movable shaft drives the four groups of pins to slide along the four groups of rectangular grooves respectively, so that the four groups of fixing parts rotate, and the fixing parts rotate out of the avoidance holes until the fixing parts squeeze the mesh electrode body, so that the mesh electrode body is clamped between the fixing parts and the supporting feet, and the mesh electrode body is fixed on the placement rod, thereby ensuring that the placement rod and the mesh electrode body rotate synchronously, so that the mesh electrode body is sprayed more evenly.

[0009] Preferably, a stacking mechanism for placing the mesh electrode body is provided below the bracket, and the stacking mechanism includes two sets of fixed plates, which are symmetrically installed on both sides below the bracket, and a plurality of sets of rollers are rotatably installed inside the fixed plates, and a stacking barrel is provided below one end of the fixed plate, and a fixed seat is provided below the stacking barrel, and a material discharge port is formed between one ends of the two sets of fixed plates, and the stacking barrel is located directly below the material discharge port, and a guide groove is provided at the lower end of the stacking barrel, and a guide rail is provided on the fixed seat, and the guide rail is slidably connected to the guide groove; When the mesh electrode body moves to the discharge port, the mesh electrode body will fall into the stacking bucket through the discharge port. The above operation is repeated in a cycle, and the mesh electrode bodies will fall into the stacking bucket one by one, realizing automatic collection of the mesh electrode body, which not only improves the automation rate of the device, but also improves the efficiency of sorting the mesh electrode body.

Under the action of the spring rebound force, the movable shaft and the roller move toward the second annular surface, so that the roller contacts the second annular surface. At the same time, the movable shaft drives the four groups of pins to slide along the four groups of rectangular grooves respectively, so that the four groups of fixings rotate, and the fixings rotate out of the avoidance holes until the fixings squeeze the mesh electrode body, so that the mesh electrode body is clamped between the fixings and the supporting feet, so that the mesh electrode body is fixed on the placement rod, thereby ensuring that the placement rod and the mesh electrode body rotate synchronously, so that the mesh electrode body is sprayed more evenly.

[0012] 3. The mesh electrode body after spraying will enter the drying box for drying. During the movement of the mesh electrode body in the drying box, the roller will roll along the second annular surface, and the mesh electrode body will be clamped between the fixing part and the supporting foot. When the mesh electrode body moves out of the drying box, the roller will roll onto the inclined surface, and the roller will be squeezed by the inclined surface, so that the roller drives the movable shaft to compress the spring, so that the four sets of fixing parts return to the placement rod again, until the roller rolls to the first annular surface, the fixation of the mesh electrode body is released, and the mesh electrode body falls on the roller. At the same time, the placement rod drives the mesh electrode body to move along the roller toward the discharge port. When the mesh electrode body moves to the discharge port, the mesh electrode body will fall into the stacking bucket through the discharge port. The above operation is repeated in a cycle, and the mesh electrode body will fall into the stacking bucket one by one, realizing the automatic collection of the mesh electrode body, which not only improves the automation rate of the device, but also improves the efficiency of sorting the mesh electrode body.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0024] like Figures 1 to 3 As shown, an electrode spraying device described in an embodiment of the present invention includes a base 1 and two groups of chains 5, a bracket 2 is fixedly installed on the base 1, two groups of transmission shafts 3 are rotatably installed in the bracket 2, two groups of sprockets 4 are installed on each group of transmission shafts 3, each group of chains 5 meshes with two groups of sprockets 4, and a plurality of groups of chain plate assemblies 6 are distributed on the outer ring of the chain 5, a mounting frame 7 and a drying box 8 are fixedly installed on the bracket 2 in sequence, two groups of arc spraying guns 9 are fixedly installed on the bracket 2, and a driving shaft 10 is rotatably installed at one end of the bracket 2, the chain plate assembly 6 includes a plate body 601, two ends of the plate body 601 are fixedly connected to the two groups of chains 5, the driving shaft 10 is rollingly connected to the plate body 601, a rotating seat 602 rotatably installed on the plate body 601, a placement rod 603 fixedly installed on the rotating seat 602, and four groups of supporting feet 604 are installed at equal angles on the outer ring of the placement rod 603.

[0025] Specifically, a resistance wire heater 81 is installed on the drying box 8, and the resistance wire heater 81 can heat the inside of the drying box 8. When the mesh electrode body needs to be sprayed, the mesh electrode body is placed on an empty group of placement rods 603, and the four groups of support legs 604 on the group of placement rods 603 support the mesh electrode body, so that the mesh electrode body is placed on the chain plate assembly 6, and then a group of transmission shafts 3 are driven to rotate by a motor, and the motor used to drive the drive shaft 10 is in a power-off state, and the group of transmission shafts 3 drives the two groups of sprockets 4 to rotate, and the sprockets 4 drive the chains 5 and several groups of chain plate assemblies 6 to do circular motion, and the attached below Figure 2The direction indicated by the middle arrow is the direction of circular motion. The several groups of plates 601 that move at the same time drive the driving shaft 10 to rotate until the mesh electrode body moves to the bottom of the mounting bracket 7. At this time, the two groups of arc spray guns 9 are respectively pointed obliquely at the upper and lower surfaces of the mesh electrode body, and the outer ring of the driving shaft 10 is in contact with the rotating seat 602. Then, the motor driving the driving shaft 10 is energized, and the motor drives the driving shaft 10 to rotate. The rotating driving shaft 10 drives the rotating seat 602 together with the placement rod 603, the supporting foot 604, and the mesh electrode body to rotate. At the same time, the two groups of arc spray guns 9 are started to spray the upper and lower surfaces of the mesh electrode body, so as to realize the spraying of the upper and lower surfaces of the mesh electrode body. When the spraying of the mesh electrode body is completed, the arc spray gun 9 is suspended, and the driving The motor of the drive shaft 10 is powered off and continues to drive several groups of chain plate assemblies 6 to make circular motions until it is directly below the next group of mobile mounting frames 7. During this process, the sprayed mesh electrode body will be moved into the drying box 8. Since the drying box 8 is heated by the resistance wire heater 81, the sprayed material on the mesh electrode body is evaporated to achieve the drying of the mesh electrode body. The dried mesh electrode body moves in a circular motion with the chain plate assembly 6, and the mesh electrode body will automatically fall onto the base 1 to achieve the unloading of the mesh electrode body. Then the above operation is repeated in a cycle. Compared with the prior art, the mesh electrode body is sprayed by two groups of arc spray guns 9 and dried by the drying box 8, thereby improving the spraying efficiency of the mesh electrode body.

[0026] Furthermore, a rubber sleeve 11 is sleeved on the end of the driving shaft 10 , and the rubber sleeve 11 is tightly attached to a set of plates 601 .

[0027] Specifically, by setting the rubber sleeve 11, direct contact between the drive shaft 10 and the plate body 601 and the rotating seat 602 is avoided, thereby reducing wear between the drive shaft 10 and the plate body 601 and the rotating seat 602 and increasing the service life of the drive shaft 10 and the plate body 601 and the rotating seat 602.

[0028] like Figures 4 to 6As shown, the chain plate assembly 6 also includes a movable shaft 605, the movable shaft 605 is inserted into the placement rod 603, a spring 606 sleeved on the placement rod 603, four groups of fixing members 607 distributed at equal angles around the end of the movable shaft 605, four groups of avoidance holes 6031 are opened at equal angles on the placement rod 603, the four groups of fixing members 607 are respectively hinged to the four groups of avoidance holes 6031, four groups of avoidance grooves 6052 are opened at equal angles on the end of the movable shaft 605, a rectangular groove 6071 is opened on the fixing member 607, and the fixing member One end of 607 is located in the avoidance groove 6052, and a pin shaft 6053 is set in each of the four groups of avoidance grooves 6052. The pin shaft 6053 is located in the rectangular groove 6071. The other end of the movable shaft 605 is rotatably installed with a roller 6051. A guide ring 201 is set in the bracket 2. The two ends of the guide ring 201 are respectively mounted on two groups of transmission shafts 3. The roller 6051 is rotatably connected to the inner ring of the guide ring 201. The inner ring of the guide ring 201 is composed of a first ring surface 2011, a second ring surface 2012, and an inclined surface 2013.

[0029] Specifically, when the driving shaft 10 drives the rotating seat 602 to rotate together with the placement rod 603, the support foot 604, and the mesh electrode body, the rotation of the mesh electrode body is achieved by the friction between the support foot 604 and the mesh electrode body. However, the friction between the support foot 604 and the mesh electrode body is limited, resulting in the inability to synchronize the rotation between the placement rod 603 and the mesh electrode body, which results in uneven spraying of the mesh electrode body. Therefore, after the mesh electrode body is placed on the chain plate assembly 6, the spring 606 in the chain plate assembly 6 is in a compressed state, and the roller 6051 on the chain plate assembly 6 is on the first annular surface 2011. When a plurality of groups of chain plate assemblies 6 are driven to make circular motions, the roller 6051 will be moved by the first annular surface 2011. 2011 rolls toward the second annular surface 2012, and under the action of the rebound force of the spring 606, the movable shaft 605 together with the roller 6051 moves toward the second annular surface 2012, so that the roller 6051 contacts the second annular surface 2012, and at the same time, the movable shaft 605 drives the four groups of pins 6053 to slide along the four groups of rectangular grooves 6071 respectively, so that the four groups of fixing parts 607 rotate, and the fixing parts 607 rotate out of the avoidance holes 6031 until the fixing parts 607 are squeezed onto the mesh electrode body, so that the mesh electrode body is clamped between the fixing parts 607 and the supporting feet 604, so that the mesh electrode body is fixed on the placement rod 603, thereby ensuring that the placement rod 603 and the mesh electrode body rotate synchronously, so that the mesh electrode body is sprayed more evenly. Embodiment 2

[0030] like Figure 7 and Figure 8As shown, compared with Example 1, another embodiment of the present invention is: a stacking mechanism 12 for placing the mesh electrode body is arranged below the bracket 2, and the stacking mechanism 12 includes two groups of fixed plates 121, and the two groups of fixed plates 121 are symmetrically installed on both sides below the bracket 2, and a plurality of groups of rollers 122 are rotatably installed on the inner side of the fixed plate 121, a stacking barrel 123 is arranged below one end of the fixed plate 121, and a fixed seat 124 is arranged below the stacking barrel 123, and a discharge port 125 is synthesized between one ends of the two groups of fixed plates 121, the stacking barrel 123 is located directly below the discharge port 125, and a guide groove 126 is opened at the lower end of the stacking barrel 123, and a guide rail 127 is arranged on the fixed seat 124, and the guide rail 127 is slidably connected to the guide groove 126.

[0031] Specifically, the mesh electrode body after spraying will fall onto the base 1, and the staff will need to sort it out before proceeding to the next step. Since the position of the mesh electrode body that falls on the base 1 is not fixed, it is troublesome for the staff to collect it, which affects the staff's sorting efficiency. Therefore, the mesh electrode body after spraying will enter the drying box 8 for drying. During the movement of the mesh electrode body in the drying box 8, the roller 6051 will roll along the second annular surface 2012, and the mesh electrode body will be clamped between the fixing piece 607 and the supporting foot 604. When the mesh electrode body moves out of the drying box 8, the roller 6051 will roll onto the inclined surface 2013, and the roller 6051 will be affected by the inclined surface 2013. The roller 6051 is squeezed to drive the movable shaft 605 to compress the spring 606, so that the four sets of fixing parts 607 return to the placement rod 603 again, until the roller 6051 rolls onto the first annular surface 2011, thereby releasing the fixation of the mesh electrode body and allowing the mesh electrode body to fall onto the roller 122. At the same time, the placement rod 603 drives the mesh electrode body to move along the roller 122 toward the discharge port 125. When the mesh electrode body moves to the discharge port 125, the mesh electrode body will fall into the stacking bucket 123 through the discharge port 125. The above operation is repeated in a cycle, and the mesh electrode bodies will fall into the stacking bucket 123 one by one, thereby realizing automatic collection of the mesh electrode bodies. This not only improves the automation rate of the device, but also improves the efficiency of sorting the mesh electrode bodies.

[0032] Working principle: the mesh electrode body is placed on an empty group of placement rods 603, and the four groups of support feet 604 on the group of placement rods 603 support the mesh electrode body, so that the mesh electrode body is placed on the chain plate assembly 6, and then a group of transmission shafts 3 are driven to rotate by a motor, and the motor used to drive the drive shaft 10 is in a power-off state. The group of transmission shafts 3 drives two groups of sprockets 4 to rotate, and the sprockets 4 drive the chains 5 and several groups of chain plate assemblies 6 to make circular motions. At the same time, the moving groups of plates 601 drive the drive shaft 10 to rotate until the mesh electrode body moves to the bottom of the mounting frame 7. At this time, the two groups of arc spray guns 9 are respectively pointed obliquely at the upper and lower surfaces of the mesh electrode body, and the outer ring of the drive shaft 10 contacts the rotating seat 602. Then the motor driving the drive shaft 10 is energized, and the motor drives the drive shaft 10 to rotate, and the rotating drive shaft 10 drives the rotating seat 602 rotates together with the placement rod 603, the support foot 604, and the mesh electrode body, and two groups of arc spray guns 9 are started at the same time to spray the upper and lower surfaces of the mesh electrode body, so as to realize the spraying of the upper and lower surfaces of the mesh electrode body. When the mesh electrode body is sprayed, the arc spray gun 9 is suspended, and the motor driving the drive shaft 10 is powered off, and several groups of chain plate assemblies 6 are continued to be driven to make circular motions until the next group of mobile mounting frames 7 are directly below. In this process, the sprayed mesh electrode body will be moved into the drying box 8. Since the drying box 8 is heated by the resistance wire heater 81, the spray on the mesh electrode body is evaporated to dry the mesh electrode body. After drying, the mesh electrode body moves in a circle with the chain plate assembly 6, and the mesh electrode body will automatically fall onto the base 1 to realize the unloading of the mesh electrode body, and then the above operation is repeated in a cycle; After the mesh electrode body is placed on the chain plate assembly 6, the spring 606 in the chain plate assembly 6 is in a compressed state, and the roller 6051 on the chain plate assembly 6 is on the first ring surface 2011. When a plurality of groups of chain plate assemblies 6 are driven to make circular motions, the roller 6051 will roll from the first ring surface 2011 to the second ring surface 2012. Under the rebound force of the spring 606, the movable shaft 605 together with the roller 6051 moves toward the second ring surface 2012, so that the roller 6051 contacts the first ring surface 2011. When the second annular surface 2012 is touched, the movable shaft 605 drives the four groups of pins 6053 to slide along the four groups of rectangular grooves 6071 respectively, so that the four groups of fixing members 607 rotate, and the fixing members 607 rotate out of the avoidance holes 6031, until the fixing members 607 squeeze the mesh electrode body, so that the mesh electrode body is clamped between the fixing members 607 and the supporting legs 604, so that the mesh electrode body is fixed on the placement rod 603, thereby ensuring that the placement rod 603 and the mesh electrode body rotate synchronously; The mesh electrode body after spraying will enter the drying box 8 for drying. When the mesh electrode body moves in the drying box 8, the roller 6051 will roll along the second annular surface 2012, and the mesh electrode body will be clamped between the fixing member 607 and the supporting foot 604. When the mesh electrode body moves out of the drying box 8, the roller 6051 will roll onto the inclined surface 2013, and the roller 6051 will be squeezed by the inclined surface 2013, so that the roller 6051 drives the movable shaft 605 to compress the spring 606, so that the four sets of fixing members 607 are again Return to the placement rod 603 until the roller 6051 rolls onto the first annular surface 2011, release the fixation of the mesh electrode body, and allow the mesh electrode body to fall onto the roller 122. At the same time, the placement rod 603 drives the mesh electrode body to move along the roller 122 toward the discharge port 125. When the mesh electrode body moves to the discharge port 125, the mesh electrode body will fall into the stacking bucket 123 through the discharge port 125. Repeat the above operation in a cycle, and the mesh electrode bodies will fall into the stacking bucket 123 one by one, thereby realizing automatic collection of the mesh electrode bodies.
