Description

Technical Field

[0001] This invention relates to the field of electrode manufacturing technology, and in particular to an electrode manufacturing system. Background Technology

[0002] Hydrogen energy, as a highly efficient and environmentally friendly energy source, has received widespread attention worldwide. Water electrolysis is currently the most widely used method for producing hydrogen. Water electrolysis involves inserting electrode plates into an electrolyzer filled with electrolyte and passing a direct current through them. This ionizes hydrogen and oxygen ions. At the cathode, the hydrogen ions receive electrons and are then released as hydrogen gas.

[0003] In water electrolysis hydrogen production equipment, the electrode sheets, which play a crucial role, are typically made of nickel foam as a substrate. This foam is immersed in a dosing tank containing a precious metal solution, and the precious metal is attached to the substrate through in-situ growth. The substrate is then heated, drained, cleaned, and dried to obtain the electrode sheet. Because nickel foam is a porous material, it remains relatively fragile even after the precious metal is attached. Cleaning it requires extreme gentleness while ensuring thoroughness. Currently, the method involves clamping the electrode sheet with a high-pressure spray for cleaning. This method easily damages the clamping area, and high-pressure spraying is insufficient for thorough cleaning. Furthermore, current cleaning equipment is complex to operate, and the cleaning process is time-consuming and labor-intensive. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the purpose of the present invention is to provide an electrode sheet manufacturing system to solve the problems of easy damage and insufficient cleaning in the cleaning process during the electrode sheet manufacturing process in the prior art.

[0005] To achieve the above and other related objectives, the present invention provides a manufacturing system for an electrode sheet, comprising:

[0006] A cleaning tank, the cleaning tank having a hollow interior, with an inlet and an outlet on each side of the cleaning tank;

[0007] A conveyor belt passes through the inlet and the outlet, and transports goods from the inlet to the outlet. A sensor is installed in the hollow structure to sense the electrode plates on the conveyor belt and control the conveyor belt to stop transporting goods.

[0008] A flipping mechanism is located inside the cleaning tank and is used to flip the electrode plates.

[0009] A cleaning mechanism is used to clean the electrode sheet during the electrode sheet flipping process.

[0010] Optionally, the flipping mechanism includes a push shaft and a flipping shaft located on both sides of the conveyor belt, and a drive unit for driving the push shaft and the flipping shaft to reciprocate. The push shaft is provided with a push shaft track, and the push shaft reciprocates along the push shaft track. The flipping shaft is provided with a flipping shaft track, and the flipping shaft reciprocates along the flipping shaft track. The push shaft track and the flipping shaft track are both concentric semi-circular tracks. The radius of the push shaft track is smaller than the radius of the flipping shaft track, and the radius of the flipping shaft track is smaller than the width of the conveyor belt.

[0011] Optionally, the flipping mechanism includes a drive plate, which is slidably disposed within the cleaning tank in a direction perpendicular to the surface of the conveyor belt. The drive unit, the flipping shaft track, and the push shaft track are disposed on the drive plate.

[0012] Optionally, the drive plate is provided with conveyor rollers above the flip shaft track and the push shaft track, and the conveyor rollers are provided with conveyor chains, with the flip shaft and the push shaft disposed on the conveyor chains.

[0013] Optionally, the pusher track further includes extension sections at both ends of the semi-circular track arranged in the horizontal direction, and the driving part is a drive roller disposed between the two conveyor chains, the drive roller being connected to a drive motor.

[0014] Optionally, there are two push shafts, which are spaced apart, and the distance between the two push shafts is equal to the length of the extension section.

[0015] Optionally, a push block made of silicone material is fitted onto the push shaft, and the cross-section of the push block is rectangular; a flip block made of silicone material is fitted onto the flip shaft, and the cross-section of the flip block is triangular.

[0016] Optionally, the inner wall of the cleaning tank is provided with a sliding groove, the two ends of the drive plate are slidably connected in the sliding groove, the top of the cleaning tank is provided with an electromagnet, and the upper end of the drive plate is provided with a magnetic strip. When the electromagnet is energized, it attracts the magnetic strip, causing the drive plate to slide upward along the sliding groove.

[0017] Optionally, the electromagnet is connected to an electromagnetic switch, the conveyor belt is connected to a conveyor switch, and the sensor, the electromagnetic switch, and the conveyor switch are all electrically connected.

[0018] Optionally, the cleaning mechanism includes measuring tubes located on both sides of the flipping mechanism and a top tube located above the flipping mechanism. The measuring tubes are equipped with multiple high-pressure spray nozzles, and the lower end of the top tube is equipped with multiple water outlets. Both the measuring tubes and the top tube are connected to a water tank.

[0019] As described above, the manufacturing system of this invention is mainly used in the cleaning process during electrode sheet manufacturing. The electrode sheets, having undergone previous processing, are placed on a conveyor belt and transported to a cleaning chamber. A sensor detects the position of the electrode sheets, and the conveying stops when the electrode sheets are fully within the cleaning chamber.

Compared to existing technologies, this solution, through the coordination of the cleaning chamber, conveyor belt, flipping mechanism, and cleaning mechanism, enables rapid and convenient thorough cleaning of the electrode sheets while preventing damage during the cleaning process.

[0032] Before describing the embodiments of the present invention in detail, the application environment of the present invention will be described first. The technology of the present invention is mainly applied to the electrode sheet manufacturing process in electrolyte hydrogen production equipment, especially to the cleaning process during electrode sheet manufacturing. The present invention solves the technical problem of incomplete cleaning of electrode sheets after precious metals have adhered to them.

[0033] The specific structure of the electrode sheet manufacturing system of this invention is described in conjunction with [reference needed]. Figure 1 and Figure 4 The electrode sheet manufacturing system includes:

[0034] The cleaning tank 10 has a hollow internal structure 11, and an inlet 12 and an outlet 13 are respectively provided on both sides of the cleaning tank 10.

[0035] A conveyor belt 20 passes through the inlet 12 and the outlet 13 and conveys along the inlet 12 to the outlet 13. A sensor 21 is installed in the hollow structure 11. The sensor 21 is used to sense the electrode plates on the conveyor belt 20 and control the conveyor belt 20 to stop conveying.

[0036] A flipping mechanism is located inside the cleaning tank 10 and is used to flip the electrode plates.

[0037] A cleaning mechanism is used to clean the electrode sheet during the electrode sheet flipping process.

[0038] The cleaning chamber 10 has openings on both sides to allow the conveyor belt 20 to pass through it. To distinguish between the end of the conveyor belt 20 that enters the cleaning chamber 10 and the end that exits, the point where the conveyor belt 20 enters the cleaning chamber 10 is called the inlet 12, and the point where the conveyor belt 20 exits the cleaning chamber 10 is called the outlet 13. The sensor 21 can be an infrared sensor used to sense the electrode plates on the conveyor belt 20. After sensing that all the electrode plates have entered the cleaning chamber 10, the sensor 21 transmits a signal to the server. The server can then control the conveyor belt 20 to stop moving, allowing the electrode plates to be cleaned inside the cleaning chamber 10.

[0039] Specifically, the flipping mechanism can flip the electrode sheet along the conveyor belt 20 or perpendicular to the conveyor direction. The flipping method can be achieved by clamping and pushing to flip the electrode sheet over. The cleaning mechanism cleans the electrode sheet during the flipping process by a combination of natural water flow and high-pressure spray.

[0040] In the specific implementation process, the electrode sheets that have completed the previous processing are placed on the conveyor belt 20, which transports the electrode sheets to the cleaning tank 10. The position of the electrode sheets is detected by the sensor 21, and the transport stops when the electrode sheets are completely within the cleaning tank 10. Then, the flipping mechanism is activated to flip the electrode sheets, and simultaneously, the cleaning mechanism is activated to clean the electrode sheets during the flipping process. Cleaning during the flipping process thoroughly cleans the electrode sheets, achieving the desired cleaning effect. In this solution, the cleaning of the electrode sheets is carried out via the conveyor belt 20 within the cleaning tank 10, making the operation simple, convenient, and labor-saving.

[0041] In some embodiments, the flipping mechanism includes a push shaft 35 and a flip shaft 32 located on both sides of the conveyor belt 20, and a drive unit that drives the push shaft 35 and the flip shaft 32 to reciprocate. The push shaft 35 is provided with a push shaft 35 track, and the push shaft 35 reciprocates along the push shaft 35 track. The flip shaft 32 is provided with a flip shaft track 34, and the flip shaft 32 reciprocates along the flip shaft track 34. The push shaft 35 track and the flip shaft track 34 are both concentric semi-circular tracks. The radius of the push shaft 35 track is smaller than the radius of the flip shaft track 34, and the radius of the flip shaft track 34 is smaller than the width of the conveyor belt 20.

[0042] In the specific implementation process, Figure 3As shown, the drive unit uses a drive motor 40 and a driven gear to drive the push shaft 35 and the flip shaft 32, causing the push shaft 35 to move along the push shaft 35 track and the flip shaft 32 to move along the flip shaft track 34. During the relative movement of the push shaft 35 and the flip shaft 32, they will approach each other and abut against the two ends of the electrode sheet, causing one end of the electrode sheet to be lifted and the other end to be pressed down to flip it. During the flipping process, the push shaft 35 and the flip shaft 32 continue to act on the electrode sheet, which enables the electrode sheet to be flipped smoothly.

[0043] In some embodiments, the flipping mechanism includes a drive plate 30, which is slidably disposed within the cleaning tank 10 in a direction perpendicular to the surface of the conveyor belt 20. The drive unit, the flipping shaft track 34, and the push shaft 35 are mounted on the drive plate 30. For example, Figure 3 As shown, in order to facilitate the setting of push shaft 35, push shaft 35 track, flip shaft 32 and flip shaft track 34, a drive plate 30 can be set above the cleaning tank 10. In order for the drive plate 30 to cooperate with the use of push shaft 35 and flip shaft 32, the drive plate 30 can be slidably set along the cleaning tank 10. When the flipping mechanism is in use, the drive plate 30 can slide down onto the conveyor belt 20. When the flipping mechanism is not in use, the drive plate 30 can slide up away from the conveyor belt 20, so that the conveyor belt 20 can transport the electrode sheet.

[0044] In some embodiments, the drive plate 30 is provided with conveyor rollers 42 above the tilting shaft track 34 and the push shaft 35 track, and the conveyor rollers 42 are provided with a conveyor chain 43, with the tilting shaft 32 and the push shaft 35 disposed on the conveyor chain 43. For example, Figure 4 As shown, in order to make the push shaft 35 slide along the push shaft 35 track and the flip shaft 32 move along the flip shaft track 34, multiple conveying rollers 42 are rotatably arranged on the drive plate 30 above the flip shaft track 34 and the push shaft 35 track. The conveying rollers 42 are equipped with conveying chains 43. The conveying rollers 42 of the push shaft 35 track are equipped with one conveying chain 43, and the conveying rollers 42 of the flip shaft track 34 are equipped with one conveying chain 43. The conveying chain 43 can be engaged with the conveying rollers 42 to realize the conveying of the conveying chain 43. In order to enable the conveying chain 43 to fully convey, the lengths of both ends of the conveying chain 43 are much longer than the lengths of the corresponding tracks.

[0045] In some embodiments, the push shaft 35 track further includes horizontally extending sections 38 at both ends of the semi-circular track, and the driving unit is a drive roller 41 disposed between two conveyor chains 43, the drive roller 41 being connected to a drive motor 40. For example, Figure 3 As shown, the extension section 38 of the push shaft 35 track facilitates the pushing of the electrode sheet, and also facilitates the asynchronous upward movement of the push shaft 35 and the flip shaft 32, which facilitates the flipping of the electrode sheet.

[0046] In some embodiments, there are two push shafts 35, spaced apart, with the distance between the two push shafts 35 equal to the length of the extension segment 38. For example, Figure 3 As shown, the two push shafts 35 can provide good support for the electrode sheet during the flipping process, preventing the electrode sheet from falling and being damaged during the flipping process.

[0047] In some embodiments, a push block 36 made of silicone material is fitted onto the push shaft 35, and the push block 36 has a rectangular cross-section; a flip block 33 made of silicone material is fitted onto the flip shaft 32, and the flip block 33 has a triangular cross-section. For example, Figure 3 As shown, the push block 36 and flip block 33 made of silicone material can better push the electrode sheet and avoid damaging the electrode sheet by applying force. The shape of the push block 36 and flip block 33 makes it easier to push and flip the electrode sheet.

[0048] In some embodiments, the inner wall of the cleaning tank 10 is provided with a sliding groove 14, and both ends of the drive plate 30 are slidably connected within the sliding groove 14. An electromagnet 15 is provided at the top of the cleaning tank 10, and a magnetic strip 31 is provided at the upper end of the drive plate 30. When the electromagnet 15 is energized, it attracts the magnetic strip 31, causing the drive plate 30 to slide upwards along the sliding groove 14. For example, Figure 3 , Figure 4 As shown, the arrangement of electromagnet 15 and magnetic strip 31 makes it easier to control the up and down sliding of drive board 30, further making the operation of this system more convenient.

[0049] In some embodiments, the electromagnet 15 is connected to an electromagnetic switch, the conveyor belt 20 is connected to a conveyor switch, and the sensor 21 is electrically connected to both the electromagnetic switch and the conveyor switch. After the conveyor belt 20 stops conveying, the electrode plates will be flipped and cleaned. At this time, the electromagnetic switch can be used to control the electromagnet 15 to be de-energized, causing the drive plate 30 to slide down under its own gravity and begin the flipping action on the electrode plates.

[0050] In some embodiments, the cleaning mechanism includes side tubes located on both sides of the tilting mechanism and a top tube 53 located above the tilting mechanism. The side tubes are equipped with multiple high-pressure spray nozzles 52, and the lower end of the top tube 53 is equipped with multiple water outlets. Both the side tubes and the top tube 53 are connected to a water tank 50. For example, Figure 3 , Figure 4 As shown, the high-pressure spray from the measuring tube can clean the electrode plates from both sides during the flipping process, and can repeatedly clean both sides of the electrode plates twice to ensure that the electrode plates are clean. The top tube 53 directly outputs water from the outlet, and the flowing water without high pressure cleans the electrode plates, thus cleaning them thoroughly without damaging them.

[0051] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can 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 those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
