Technical Field
[0001] This utility model relates to the field of metal bipolar plate processing technology, specifically to a precision etching processing equipment for metal bipolar plates. Background Technology
[0002] Metal bipolar plates are one of the core components in fuel cells (such as proton exchange membrane fuel cells) and electrolyzers. Their surfaces typically require precision-machined channels to uniformly distribute reactant gases and coolant. Traditional metal bipolar plate processing methods mainly include stamping, mechanical milling, and photochemical etching; laser etching / laser processing technology, due to its advantages such as high precision, non-contact operation, no tool wear, good flexibility, and clean and environmentally friendly characteristics, is widely used in the field of precision manufacturing. When laser technology is applied to the precision etching of metal bipolar plates, metal vapor and tiny particles are generated during the laser etching process. These contaminants can contaminate the worktable and also obstruct the inspection camera. Furthermore, there will be a lot of dust and tiny particles on the surface of the metal bipolar plate before and after etching, which may affect the etching accuracy. To address this, we propose a precision etching processing equipment for metal bipolar plates. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a precision etching processing equipment for metal bipolar plates. The equipment uses a dust-adhesive roller in conjunction with a cleaning nozzle to clean dust and other impurities from the surface of the metal bipolar plates to prevent the accumulation of impurities from affecting the etching accuracy. At the same time, a negative pressure suction pipe is connected to an external pump to collect, separate, and adsorb the dust and harmful substances generated during etching, so as to ensure the cleanliness of the workbench and the health of the personnel. This can effectively solve the problems in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a precision etching processing equipment for metal bipolar plates, comprising a platform and an etching unit; Platform: A cabinet is installed on the top surface of the platform, a support is provided on the rear side of the top surface of the platform, and a cleaning unit is provided on the top surface of the platform; Etching unit: includes a support frame, a first linear motor, a second linear motor, an electric push rod, and a laser etcher. The first linear motor is vertically arranged inside a groove on the top surface of the platform. The support frame is provided on the top surface of the first linear motor's moving part. The second linear motor is horizontally arranged inside the support frame. The electric push rod is fixed to the top surface of the bracket. The bottom end of the electric push rod is fixedly installed to the top surface of the laser etcher. The system also includes a placement plate and a controller. The placement plate is fixed to the top surface of the second linear motor actuator, and the controller is fixed to the front side of the platform. The input terminals of the first linear motor, the second linear motor, the electric push rod, and the laser etcher are electrically connected to the output terminal of the controller, and the input terminal of the controller is electrically connected to the output terminal of an external power supply.
[0005] Starting the first and second linear motors can drive the placement plate to adjust its position, and the electric push rod can adjust the height of the laser etcher to perform precision etching on the metal bipolar plate on the top surface of the placement plate.
[0006] Furthermore, the etching unit also includes a frame, an electric telescopic rod, an air pump, a motor, a base, a dust-adhesive roller, and a cleaning nozzle. The electric telescopic rod is fixed to the bottom surface of the platform. The bottom end of the electric telescopic rod is provided with a frame that is slidably installed in a slot on the top surface of the platform. The base is fixed to the right side of the frame, and a motor is installed on the surface of the base. The output shaft of the motor is connected to the end of the dust-adhesive roller that rotates inside the frame. Cleaning nozzles are installed on both the left and right sides inside the frame. The air inlet of the cleaning nozzle is connected to the air outlet on one side of the air pump. The air pump is fixed to the bottom surface of the frame. The input ends of the electric telescopic rod, the air pump, and the motor are electrically connected to the output end of the controller. Activating the electric telescopic rod drives the frame to rise and fall, and the motor drives the dust-adhesive roller to rotate to adhere and clean impurities on the surface of the metal bipolar plate. At the same time, the air pump sprays cleaning gas through the cleaning nozzle, which effectively improves the cleaning effect of the metal bipolar plate surface and prevents impurities from adhering and affecting the accuracy of subsequent etching.
[0007] Furthermore, the cleaning unit includes a conical collection trough, a filter screen, a processing box, an inclined mesh frame, an activated carbon box, and a negative pressure suction pipe. There are two conical collection troughs, each located on one side of the top surface of the platform. There are two processing boxes, each located on the bottom surface of the platform and corresponding to the positions of the conical collection troughs. The conical collection troughs are connected to the interior of the processing boxes. An inclined mesh frame, tilted to both sides, is fixed inside the processing box. A filter screen is snapped into the mesh groove on the surface of the inclined mesh frame. The activated carbon box is slidably installed inside the processing box. The negative pressure suction pipe is installed on the bottom surface of the processing box and is connected to an external negative pressure pump to draw the gas generated during etching into the processing box. The activated carbon box adsorbs the harmful substances contained therein. The conical collection troughs, in conjunction with the filter screen, can collect and separate the impurities that have fallen off during etching, making it convenient for personnel to clean.
[0008] Furthermore, the cleaning unit also includes a pneumatic push rod, a connecting frame, a baffle, a third linear motor, a transparent cover, and a rubber ring. The third linear motor is fixed inside the bracket, and a transparent cover is provided on the front side of the third linear motor's moving part. A rubber ring is installed on the bottom surface of the transparent cover. The pneumatic push rod is fixed to the rear side of the processing box, and the bottom end of the pneumatic push rod is connected to the middle of the top surface of the connecting frame. Both sides of the top surface of the connecting frame are provided with baffles that slide and fit against the sides of the processing box. The input ends of the pneumatic push rod and the third linear motor are electrically connected to the output end of the controller. Activating the third linear motor drives the transparent cover to cover the top surface of the platform to form a sealed environment, thereby isolating the laser etching process from the external environment and effectively preventing the diffusion of contaminants.
[0009] Furthermore, it also includes hydraulic rods and fixing frames. There are two hydraulic rods, which are respectively fixed inside two grooves on the top surface of the placement plate. The outer end of the hydraulic rod is fixed with a fixing frame that is slidably installed with the groove on the top surface of the placement plate. The input end of the hydraulic rod is electrically connected to the output end of the controller. When the hydraulic rod is activated, it drives the fixing frame to clamp and fix the metal bipolar plate on the top surface of the placement plate to prevent loosening from affecting the etching accuracy.
[0010] Furthermore, it also includes a frame and a detection camera. The frame is fixed to the front end of the bracket, and the detection camera is placed inside the frame. The input end of the detection camera is electrically connected to the output end of the controller. The detection camera inside the frame monitors the position of the metal bipolar plate in real time during the etching process, thereby improving the etching accuracy.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This precision etching equipment for metal bipolar plates has the following advantages: 1. By starting the first and second linear motors, the placement plate can be adjusted in position. The electric push rod adjusts the height of the laser etcher to perform precision etching on the metal bipolar plate on the top surface of the placement plate. The detection camera inside the frame monitors the position of the metal bipolar plate in real time during the etching process, thereby improving the etching accuracy.
[0012] 2. The frame is raised and lowered by starting the electric telescopic rod. The motor drives the dust-adhesive roller to rotate and adhere and clean the impurities on the surface of the metal bipolar plate. At the same time, the air pump sprays the cleaning gas through the cleaning nozzle. This effectively improves the cleaning effect of the metal bipolar plate surface and prevents the adhesion of impurities from affecting the accuracy of subsequent etching.
[0013] 3. The gas generated during etching is drawn into the processing chamber by connecting the negative pressure suction tube to an external negative pressure pump. The activated carbon box adsorbs the harmful substances contained therein, while the cone-shaped collection tank with a filter screen can collect and separate the impurities that fall off during etching.
