Description

Technical Field

[0001] This utility model relates to the field of coating technology, and in particular to an electrode coating device. Background Technology

[0002] Electrode coating devices are used to uniformly coat specific materials on the surface of electrodes to improve electrode performance. They are widely used in fuel cells, water electrolysis for hydrogen production, electrochemical sensors and other fields. Among them, ultrasonic coating spraying is a high-precision and high-uniformity coating preparation process that uses ultrasonic atomization technology. Liquid materials are atomized into micron-sized particles by an ultrasonic nozzle, and then uniformly deposited on the surface of the substrate by a carrier gas to form a coating.

[0003] The existing utility model patent with publication number CN220716299U discloses a glass carbon graphite electrode coating device. It describes a device that "places graphite electrodes between rotating rollers, drives the rollers to rotate via a motor, thereby rotating the graphite electrodes. A screw drive then drives the nozzle to reciprocate left and right inside the housing, achieving uniform coating." While this solves the problem of "uneven coating in existing glass carbon graphite electrode coating devices," the previous coating equipment required manual opening of the housing door after electrode coating to remove the electrodes and replace the substrate. Frequent opening of the door easily leads to a large influx of external dust into the coating environment, affecting the product. Furthermore, the manual electrode disassembly and assembly process is time-consuming and discontinuous. Therefore, this invention proposes an electrode coating device. Utility Model Content

[0004] Therefore, it is necessary to provide an electrode coating device to address the above-mentioned technical problems and ensure that the equipment can maintain good working condition even in harsh environments.

[0005] In order to solve the above-mentioned technical problems, the present invention solves the problem that frequent opening of doors can easily cause a large amount of external dust to enter the spraying environment through the following technical solution.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An electrode coating device comprising:

[0008] A coating spraying equipment box, wherein a hinged door is connected to the front of the coating spraying equipment box, an observation window is embedded in the surface of the door, an ultrasonic spraying device body is installed in the inner cavity of the coating spraying equipment box, and side holes are opened on both side walls of the coating spraying equipment box.

[0009] Multiple connecting plates are provided, with a material carrier plate between two adjacent connecting plates. A material discharge groove is provided at the top of the material carrier plate, and positioning plates are provided on both sides of the inner cavity of the material discharge groove. A bottom groove is provided at the bottom of the material carrier plate, and a bidirectional threaded rod is provided in the inner cavity of the bottom groove.

[0010] In a preferred embodiment of the electrode coating device provided by this utility model, a pair of movable holes are provided on both sides of the bottom end of the inner wall of the feeding trough, and a movable plate is movably inserted into the inner cavity of the movable hole.

[0011] In a preferred embodiment of the electrode coating device provided by this utility model, the top end of the movable plate is fixedly connected to the bottom end of the positioning plate on the same side, and a movable plate is fixedly connected to the bottom of the opposite surfaces of the two movable plates on the same side.

[0012] In a preferred embodiment of the electrode coating device provided by this utility model, one end of the bidirectional threaded rod is rotatably connected to one side of the inner wall of the bottom groove, and the other end of the bidirectional threaded rod rotatably passes through the other side of the inner wall of the bottom groove and is fixedly connected to a knob.

[0013] In a preferred embodiment of the electrode coating device provided by this utility model, the two movable plates are respectively threaded to the two ends of the bidirectional threaded rod, and the two movable plates are distributed on two opposite threads on the bidirectional threaded rod.

[0014] In a preferred embodiment of the electrode coating device provided by this utility model, a pair of fixing plates are fixedly connected between the two side walls of the material carrier plate and the two adjacent connecting plates.

[0015] In a preferred embodiment of the electrode coating device provided by this utility model, a handle is fixedly connected to one side wall of the outer connecting plate, and a stop block is fixedly connected to one side wall of the handle.

[0016] In a preferred embodiment of the electrode coating device provided by this utility model, the two side walls of the coating spraying equipment box are fixedly connected to support frames, and the two sides of the top of the support frames are fixedly connected to guide plates.

[0017] In a preferred embodiment of the electrode coating device provided by this utility model, the two guide plates are distributed on both sides of the side hole.

[0018] In a preferred embodiment of the electrode coating device provided by this utility model, the shape of the side hole is adapted to the connecting plate, the two material carrier plates are symmetrically distributed, and the number of connecting plates is three.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This utility model provides an electrode coating device with side holes. While the current electrode plate is being coated inside the coating spraying equipment box, the electrode plate to be replaced can be pre-placed on an external carrier plate. After the electrode plate is coated, the carrier frame, composed of a connecting plate, a carrier plate, and a fixing plate, is moved. The side holes allow for rapid replacement of the external electrode plate with the coated one, preventing large amounts of external dust from entering the device during electrode plate replacement. This achieves continuous and efficient spraying operations. During electrode plate coating, the connecting plate partially blocks the side holes, effectively preventing external dust from entering the equipment box and ensuring coating quality.

[0021] The present invention provides an electrode coating device, which, by setting a positioning plate, allows the bidirectional threaded rod to be rotated when the electrode material plate is placed in the feeding trough. This causes the movable plate to move relative to the two positioning plates via the moving plate, thereby clamping electrode material plates of different sizes and ensuring the stability of the electrode material plates during movement and spraying.

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention. Example

[0032] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 An electrode coating device includes a coating spraying equipment box 1. The front of the coating spraying equipment box 1 is hinged with a switch door 2. An observation window 3 is embedded on the surface of the switch door 2 to monitor the spraying process in real time and ensure the quality of the process. An ultrasonic spraying device body 4 is installed in the inner cavity of the coating spraying equipment box 1. Side holes 5 are opened on both sides of the coating spraying equipment box 1 to serve as the inlet and outlet channels of the material carrier plate 7, so as to realize the continuity of the spraying operation.

[0033] Multiple connecting plates 6 are provided, with a material carrier plate 7 between two adjacent connecting plates 6. The top of the material carrier plate 7 is provided with a material feeding groove 8 to provide a space for the electrode material plate and to be fixed in conjunction with the positioning plate 9. Positioning plates 9 are provided on both sides of the inner cavity of the material feeding groove 8. The electrode material plate is clamped by relative movement to accommodate different sizes and specifications. The bottom end of the material carrier plate 7 is provided with a bottom groove 10. The inner cavity of the bottom groove 10 is provided with a bidirectional threaded rod 13 to drive the positioning plate 9 to move and achieve rapid positioning. A pair of fixing plates 16 are fixedly connected between the two side walls of the material carrier plate 7 and the two adjacent connecting plates 6. A handle 17 is fixedly connected to one side wall of the outer connecting plate 6. The handle 17 is L-shaped and a stop block 18 is fixedly connected to one side wall of the handle 17. When the electrode material plate on the same side of the material carrier plate 7 is placed directly below the ultrasonic spraying device body 4, the stop block 18 is in contact with the surface of the coating spraying equipment box 1, which plays a limiting role.

[0034] Preferably, a pair of movable holes 11 are provided on both sides of the bottom end of the inner wall of the feeding trough 8. A movable plate 12 is movably inserted into the inner cavity of the movable hole 11. The movable hole 11 and the movable plate 12 play a role in limiting and guiding the positioning plate 9. The top end of the movable plate 12 is fixedly connected to the bottom end of the positioning plate 9 on the same side. Movable plates 15 are fixedly connected to the bottom of the opposite sides of the two movable plates 12 on the same side. One end of the bidirectional threaded rod 13 is rotatably connected to one side of the inner wall of the bottom groove 10. The other end of the bidirectional threaded rod 13 rotatably passes through the other side of the inner wall of the bottom groove 10 and is fixedly connected to a knob 14. The two movable plates 15 are respectively threaded to the two ends of the bidirectional threaded rod 13. The two movable plates 15 are distributed on two opposite threads on the bidirectional threaded rod 13. When the bidirectional threaded rod 13 rotates, the two movable plates 15 on it will cause the two positioning plates 9 to move relative to each other or in opposite directions, so as to realize the positioning of electrode plates of different sizes.

[0035] Preferably, support frames 19 are fixedly connected to both sides of the coating spraying equipment box 1, and guide plates 20 are fixedly connected to both sides of the top of the support frame 19. These guide plates 20 play a role in limiting, guiding and supporting the material rack composed of components such as connecting plate 6, material loading plate 7 and fixing plate 16. The two guide plates 20 are distributed on both sides of the side hole 5.

[0036] Preferably, the shape of the side hole 5 is adapted to the connecting plate 6, the two material carrier plates 7 are symmetrically distributed, and the number of connecting plates 6 is three.

[0037] The electrode coating device provided by this utility model is used as follows: First, when spraying the electrode material plate, the operator places the electrode material plate in the material feeding trough 8, and turns the knob 14 by hand, causing the bidirectional threaded rod 13 to rotate. The two movable plates 15 then cause the moving plate 12 to move relative to the two positioning plates 9 under the limiting action of the moving hole 11 until they come into contact with the electrode material plate, thus clamping it. The ultrasonic spraying device body 4 is used to spray the coating onto the electrode material plate. During the spraying process, the operator can place the electrode material plate on the external carrier plate 7, and then fix the electrode material plate by turning the knob 14 on the carrier plate 7, so that the coating can be sprayed. After the electrode plate inside the equipment box 1 has been coated, the operator can move the material carrier frame, which consists of connecting plate 6, material carrier plate 7 and fixing plate 16, so that the material carrier plate 7, which was originally placed on the outside, can replace the material carrier plate 7 inside through the side hole 5. When the abutment block 18 on one side of the original material carrier plate 7 comes into contact with the coating spraying equipment box 1, the electrode plate is replaced. At this time, the two connecting plates 6 are placed in the side hole 5 to prevent external dust from entering the interior of the coating spraying equipment box 1 through the side hole 5. Then, the operator can remove the coated electrode plate from the material carrier plate 7 by turning the knob 14, and then replace and fix the uncoated electrode plate. This cycle is repeated to achieve continuous operation.
